Description

[0001] Wireless Signal Transmitter-Receiver [0002]

The present invention relates to a radio signal transceiver. And more particularly, to a wireless signal transceiver capable of selectively minimizing a reach of a wireless signal transmitted from a wireless signal transceiver to a display device by selectively reflecting a wireless signal according to an installation position of a display device and a wireless signal transceiver.

The display device is connected to a wired broadcast, a VHS, a DVD, or an audio system to receive a video signal or an audio signal, and provides video and sound to a user.

In this way, the display device is connected to a VHS, a DVD, or an AUDIO system in a wired manner in order to receive a video signal or an audio signal in connection with a cable broadcasting, a VHS, a DVD or an AUDIO system and provide an image and sound to a user.

Therefore, in order to connect with various external devices, a number of cables connected to the external devices must be connected to the display device.

However, a method of wirelessly connecting an external device and a display device has been introduced. That is, a technique of wirelessly transmitting a video signal from an external device to a display device is used.

That is, various external devices are connected to one radio signal transceiver through wired / wireless lines, and the radio signal transceiver can wirelessly transmit / receive signals to / from the display device.

The IEEE 802.11n or UWB scheme is used as a method for enabling such wireless transmission. The IEEE 802.11n scheme or the UWB scheme is a scheme in which a reception distance is long (about 20 m) due to the generation of a radial wave, There is a disadvantage that high capacity data transmission is not possible in order to provide a full HD image like a full high definition display device.

In order to overcome the limitations of the conventional radio system described above, it has become possible to transmit and receive high capacity data by using radio waves having a high frequency of 60 GHz. Using high-bandwidth frequencies of 60 GHz, video signal transmission and other high-capacity data transmission for full high definition (HD) imaging is possible.

However, due to the characteristics of the high-frequency frequency, there is a limitation in the reception area due to the disadvantage that the directivity of the radio wave having the high-band frequency and the reaching distance of the radio new Hong are less than about 100 meters (m).

In particular, a radio signal transceiver may be located at a lower portion of the display device than in a case where the radio signal transceiver and the display device are disposed at positions facing each other. For example, in many cases, a display device is installed on one side wall of a living room or the like, and various external devices including a wireless signal transceiver are installed around the periphery (for example, a lower portion of the display device).

That is, a receiving module equipped with a transmitting / receiving chip of a wireless signal is mounted on the front surface of a display device, and a wireless signal transmitted from the wireless signal transceiver will reach the wireless signal receiving chip in such a way that the wireless signal is reflected on the opposite wall surface or the like.

However, as described above, due to the nature of the high-frequency frequency, the range of arrival of the radio wave is short, so that a display device is installed on one side wall and various external devices including a radio signal transceiver are installed around the periphery There is a need for a method for solving the problems of transmission and reception of radio waves that can occur when the radio wave is reached through a process of reflection on the opposite wall surface (reaching distance of 10 meters or more in total).

The present invention reduces the arrival distance of a wireless signal of a wireless signal transceiver that transmits a signal provided from various external devices to a display device using a wireless signal having a high band frequency and reduces the sensitivity of the wireless signal received by a display device or the like The present invention provides a radio signal transceiver capable of improving the communication quality of a radio signal.

According to an aspect of the present invention, there is provided a wireless signal transmitting / receiving chip for receiving a radio signal transmitted in a front direction of the housing or a front direction of the housing, And a reflection plate that is selectively displaced from the front surface of the radio signal transmitting / receiving chip so as to reflect the radio signal transmitted from the radio signal transmitting / receiving chip in a direction other than the front direction of the housing .

In this case, the reflection plate may be rotatably mounted on the housing.

The reflector may be selectively inserted into an insertion groove formed in the housing, and the lever may be rotatably coupled to a side surface of the housing by a hinge shaft.

Here, a handle may be further provided at the other end of the lever.

The insertion groove may be an opening formed in a front surface of the housing and a side surface of the housing coupled with the lever, and a space formed inside the opening.

In this case, the space for forming the insertion groove may be formed in the horizontal direction.

The reflection plate may be selectively inserted into the housing or may be retractably mounted on the housing to be drawn out of the housing.

Here, a support member for connecting the housing and the reflector may be further provided, and the support member may be hinged to the reflector.

In addition, the reflection plate and the support member may be inserted or withdrawn from below the radio signal transmission / reception chip, and the reflection plate may be hinged so as to be rotated in the front direction of the radio signal transmission / reception chip after being drawn out.

In this case, the reflection plate may be inserted into or pulled out of the housing in an inclined state.

Here, the reflection plate may be made of metal, or the reflection plate may be coated with a metal material.

The wireless signal transmitting / receiving chip may transmit or receive a wireless signal including image information having a frequency band of 50 GHz to 70 GHz.

The wireless signal transceiver according to the present invention can shorten the reach of a wireless signal of a wireless signal transceiver that transmits a signal provided from various external devices to a display device using a wireless signal having a high band frequency.

In addition, according to the wireless signal transceiver according to the present invention, the sensitivity of a wireless signal received by a display device or the like can be improved.

In addition, according to the radio signal transceiver according to the present invention, it is possible to limit the installation position of the radio signal transceiver and the display device.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments disclosed herein are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Like reference numerals designate like elements throughout the specification.

1 is a perspective view of a wireless signal transceiver 100 and a display device 300 according to the present invention. The display device 300 includes a panel 320 on which an image is displayed, a housing 310 that houses the panel 320, a wireless signal transmitter 320 mounted in the housing 310, And a circuit board 220 on which a receiving chip 210 for receiving a signal is mounted. The circuit board 220 on which the wireless signal receiving chip 210 for receiving the wireless signal is mounted may be composed of one receiving module 200. That is, the display device 300 may be provided as a module for receiving a radio signal separately from the main circuit board of the display device 300.

The wireless signal receiving chip 210 mounted on the display device 300 may be mounted inside the front housing 310 of the display device 300. The front housing 310 may be generally constructed of a plastic material. A radio wave used for wireless transmission of a signal in the display device 300 may be a high-band radio wave having a frequency of about 50 Ghz to 70 Ghz (for example, 60 Ghz).

These high frequency frequencies have the following transmission characteristics. The transmittance of the radio wave having the high frequency is determined according to the incident angle of the glass material, and in the case of the wood, it is reflected or transmitted according to the moisture content contained therein.

In addition, the radio wave having the high-band frequency is characterized by being reflected without being transmitted in the case of a metal material.

On the other hand, plastics can penetrate and reflect on the paint painted on plastic.

Accordingly, if the housing 310 of the display device 300 enclosing the panel 320 shown in FIG. 1 is provided with plastic, the radio signal transmitted from the radio signal transceiver 100 is transmitted through the housing 310 And can reach the wireless signal receiving chip 210 located inside the housing 310.

Of course, an opening may be formed in the housing 310 of the display device 300 so that the receiving chip 210 is exposed to expose the receiving chip 210. However, when the aesthetic finish of the housing 310 is considered The receiving chip 210 may be embedded in the housing 310.

The plastic housing 310 may penetrate through the plastic housing 310 to reach the radio signal receiving chip 210 according to the radio wave characteristics having the high frequency band described above. However, as described above, the high frequency frequency is shortened , The reaching range of radio waves is limited.

The display device 300 receives and displays a video signal transmitted from the wireless signal transceiver 100 according to the present invention.

The wireless signal transceiver 100 may be connected to various external devices capable of providing video signals.

The wireless signal transceiver 100 may convert a video signal received from the external device into a wireless signal and transmit the wireless signal, or may receive a wireless signal. The wireless signal transmitted from the wireless signal transceiver 100 is propagated from the wireless signal transmitting / receiving chip 310 of the display device. As described above, the wireless signal transmitted from the wireless signal transceiver 100 is transmitted to the high- For example, a radio wave having a frequency of 60 GHz may be used.

The radio signal transceiver 100 according to the present invention selectively transmits a radio signal transmitted from the radio signal transmitting and receiving chip 110 to a front side of the radio signal transmitting and receiving chip 110 And a reflective plate 120 that is displaced in a spaced apart state.

The reflection plate serves to reduce a reaching distance of a radio signal transmitted from the radio signal transmitting / receiving chip 110 to reach the display device 300.

FIG. 2 is a conceptual diagram illustrating a process of reflecting a radio signal between the wireless signal transceiver 100 and the display device 300 according to the present invention.

The wireless signal transmitted from the wireless signal transceiver 100 is reflected on the opposite wall surface or the like so that the wireless signal transceiver 100 does not face the display device 300, And reaches device 300.

However, the radio signal transmitted from the radio signal transceiver may not reach the display device 300 due to the directivity of the radio wave and the short distance of the radio wave.

3, when the display device 300 is provided above or below the wireless signal transceiver 100, the wireless signal transceiver 100 reflects the wireless signal transmitted from the wireless signal transceiver 100, And a reflector 120 for shortening the distance.

The reflection plate 120 is selectively displaced from the front surface of the wireless signal transmission / reception chip 110 so as to reflect the wireless signal transmitted from the wireless signal transmission / reception chip 110 in a direction other than the front direction of the housing .

2, the reflection plate is selectively disposed on the front surface of the wireless signal transmitting / receiving chip 110 so as to reflect the wireless signal transmitted from the wireless signal transmitting / receiving chip 110 in a direction other than the front direction of the housing. The method of displacing the reflector 120 in a spaced apart state is a method of rotatably mounting the reflector 120 on the housing of the wireless signal transceiver 100.

A lever 130 is provided at one end of the reflection plate 120. The reflection plate 120 is selectively inserted into an insertion groove 150 formed in the housing and the lever 130 is hinged to a side of the housing. And is rotatably coupled by an axis 135.

Therefore, the lever 130 rotatably transmits the radio signal transmitted from the RF signal transmitting and receiving chip 110 to the wireless signal transmitting and receiving unit 100 of the display device 300, To the direction of the wireless signal receiving module 200 equipped with the signal receiving chip.

The lever 130 is rotatably coupled to the hinge shaft 135 so that the reflection plate 120 reflects the radio signal transmitted from the radio signal transmitting and receiving chip 110 upward or downward of the radio signal transmitter- .

3 is a perspective view illustrating a rotation state of the reflection plate 120 of the wireless signal transceiver 100 according to the present invention.

3 (a) shows a state where the reflection plate 120 is inserted into an insertion groove 150 formed in a housing of the radio signal transceiver 100, and FIG. 3 (b) Receiving chip 110 to selectively reflect a radio signal transmitted from the radio signal transmitting and receiving chip 110 in a direction other than the front direction of the housing.

In the embodiment shown in FIG. 3 (b), the reflection plate 120 may be rotated at various angles, and the rotation angle may be variously changed according to the position of the display device.

The insertion groove 150 includes a front surface 101 of the housing of the wireless signal transceiver 100 and openings 101a and 102a formed in a side surface 102 of the housing coupled with the hinge shaft 135, And the insertion groove 150 may be formed in a substantially horizontal direction.

One end of the lever 130 is connected to a side surface of the reflector 120 and a handle 140 is formed at the other end connected to the hinge shaft 135. Further, the hinge shaft 135 may be provided with a friction ring (not shown) or the like so that a frictional force is applied to the hinge shaft 135 so that the angle of rotation of the reflection plate 120 is adjusted and the adjusted angle is maintained.

The frictional force by the friction ring may be such that the angle of the reflection plate 120 is adjusted after the angle of the reflection plate 120 is maintained, so that no frictional force should be provided so as to make it difficult to adjust the angle of rotation.

The frictional force can be controlled by adjusting the fastening strength of the hinge shaft 135.

The reflection plate 120 reflects a high-band radio signal transmitted from the radio signal transmitting / receiving chip 110.

The reflection plate 120 may be made of a metal material to prevent the radio waves having the high frequency band from being transmitted. If the reflection member 230 is made of a plastic material, the reflection member 230 may be coated with a metallic material capable of reflecting the high frequency band.

Figure 4 illustrates another embodiment of a wireless signal transceiver 100 in accordance with the present invention. 4, a reflector 120 for reflecting a radio signal transmitted from the radio signal transmitting / receiving chip 110 is inserted into the housing of the radio signal transceiver 100, And can be movably mounted to the housing in a retractable manner.

As shown in FIG. 4, the reflection plate 120 is movably mounted in the housing of the radio signal transceiver 100. The reflection plate 120 is mounted to be rotatable in a state of being drawn out from the housing of the radio signal transceiver 100.

4 (a) shows a state in which the reflection plate 120 is inserted into the housing, and FIG. 4 (b) shows a state in which the reflection plate 120 is rotated in a drawn state.

The reflection plate 120 may be hinged to a separate support member 125. The insertion groove 150a may be a space formed horizontally inward from an opening formed in the front surface of the housing.

When the reflection plate 120 is inserted into the insertion groove 150a formed in the housing, the reflection plate 120 can be inserted or drawn out while being horizontally expanded with respect to the support member 125. [

The reflection plate 120 and the support member 125 are rotatably coupled to each other by a hinge 123 and the range of the reflection plate 120 and the hinge 123 are extended out from the insertion groove 150a. It is preferable to be drawn out to such an extent that it can be exposed.

This is because the reflection plate 120 and the hinge 123 must be exposed to the outside so that the reflection plate 120 can rotate the hinge 123 about the support member 125 with the rotation axis.

The support member 125 may be slidable in the insertion groove 150a but not separated from the housing. Therefore, the support member 125 may be provided with a locking protrusion (not shown) so as not to be separated from the insertion groove 150a.

A ring handle 140b or the like may be provided on the reflection plate 120 to facilitate the drawing of the reflection plate. The shape of the handle can be varied.

Figure 5 illustrates another embodiment of a wireless signal transceiver 100 in accordance with the present invention.

The reflection plate 120 of the embodiment shown in FIG. 5 is similar to the embodiment shown in FIG. 4 in that it is inserted or withdrawn from the insertion groove 150b formed in the housing so as to be movable back and forth, Are inclined at a constant inclination.

As shown in FIG. 5 (b), when the part of the reflection plate 120 is pulled out from the inclined insertion groove 150b, it is inclined to the front face of the wireless signal transmitting / receiving chip 110. [ The wireless signal transmitted from the wireless signal transmitting and receiving chip 110 is reflected by a reflection plate 120 disposed on the front surface of the wireless signal transmitting and receiving chip 110 and is then displayed on a display device So that the reaching distance of the radio signal can be reduced.

In addition, in the embodiment shown in FIG. 5, the ring handle 140b for facilitating the pulling-out of the reflection plate 120 may be provided is the same as the embodiment shown in FIG.

In the embodiment shown in FIGS. 3 to 5, if the reflection plate 120 is not rotated or drawn, the radio signal transmitted from the radio signal transceiver will advance in the front direction of the radio signal transceiver.

However, if a reflector is used that is selectively displaced in a state of being spaced apart from the front face of the radio signal transmitting / receiving chip so as to reflect the radio signal transmitted from the radio signal transmitting / receiving chip in a direction other than the front direction of the housing, It is possible to reflect the wireless signal to the display device in which the wireless communication device is located, thereby shortening the reach distance of the wireless signal.

The reflection plate 120 can be selectively displaced so as to be positioned in front of the radio signal transmitting / receiving chip 110. Thus, the user rotates or draws the reflection plate 120 according to the position of the display device and the radio signal transceiver, Or the reflection plate 120 may be inserted into the insertion groove.

While the present invention has been particularly shown and described with reference to preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims. .
