Description

a handheld device

technical field

The utility model relates to the technical field of mobile terminals, in particular to a handheld device.

Background technique

In order to save space and make the structure more compact, existing handheld devices (such as mobile phones and tablet computers) generally only have one Universal Serial Bus (USB) interface. However, there is only one USB interface, so that the handheld device cannot meet the needs of users in certain application scenarios, and the user experience is not good. For example, when the mobile phone is connected to a USB slave device (such as a U disk) to read and write data through this USB interface, it cannot be charged at the same time, and the USB interface can only be used for charging after the data transmission operation is completed. For another example, when the mobile phone is connected to a USB external device through the USB interface and needs to be connected to another external device for use together, since the USB interface is already occupied, it cannot meet the user's use requirements in this application scenario. It can be seen from the above that the existing handheld devices have poor user experience.

Utility model content

In order to achieve the above object, the technical solution of the utility model is achieved in that:

The utility model provides a handheld device, which includes: a micro control unit, and two or more universal serial bus USB female connectors electrically connected to the micro control unit;

Micro control unit for controlling the operation of the handheld device;

The USB female connector is used to perform signal interaction with the external device according to the signal instruction of the micro control unit when connected to the external device through the USB cable.

Preferably, the number of USB female connectors is two.

Preferably, the two USB female connectors are of the same or different types.

Preferably, when the two USB female connectors are of the same type, both USB female connectors are USB Type-C female connectors.

Preferably, when the two USB connectors are of different types, one of the USB female connectors is a Micro USB female connector, and the other USB female connector is a USB Type-C female connector.

The beneficial effects of the utility model are: the technical scheme of the utility model is provided with two or more USB female connectors on the handheld device, and the two USB female connectors are connected to the micro control unit of the handheld device, And according to the control command of the micro-control unit, the signal interaction with the connected peripherals is carried out, which ensures that the data transmission operation and the charging operation can be carried out at the same time, and ensures that two external devices can be connected at the same time to cooperate with the handheld device, which satisfies the needs of users. The use requirements have improved the user experience.

detailed description

The core idea of the utility model is: in the prior art, only one USB interface is provided on the handheld device for the sake of saving space and cost, and this leads to the fact that the handheld device cannot meet the user's need to connect multiple USB devices in some scenarios. demand, poor user experience. To solve this problem, the embodiment of the present invention provides a handheld device, which is provided with two or more USB interfaces, which is convenient for users to use and optimizes user experience.

Fig. 1 is a structural schematic diagram of a handheld device according to an embodiment of the present invention. Referring to Fig. 1, the handheld device 10 includes: a first USB female connector 101 and a second USB female connector 102, and the first USB female connector Both the connector 101 and the second USB female connector 102 are electrically connected to the microcontroller unit 103 . When the handheld device is connected to an external device through a USB cable inserted into the first USB female connector 101 and/or the second USB female connector 102, the handheld device can be connected to the external device through the first USB female connector 101 or the second USB female connector 101. The USB female connector 102 performs signal interaction with external devices. The interactive signals here include: data signals and current signals.

In this embodiment, the two USB female connectors are of the same type. For example, both are USB Type-C female connectors. When the two USB female connectors are both USB Type-C, connect to an external device through a USB data cable compatible with the USB female connector.

In another embodiment, the types of the two USB connectors of the handheld device of the present invention are different, for example, one of the USB female connectors is a Micro USB female connector, and the other USB female connector is a Micro USB female connector. The type is a USB Type-C female connector. If the types of the two USB interfaces are different, the handheld device needs to be connected to the external device through the corresponding USB data cable. Micro USB is a portable version of the USB 2.0 standard. Micro USB is formulated by the USB Standardization Organization (USB Implementers Forum, USB-IF). In the case of personal computer PC), data transmission can also be directly realized between handheld devices installed with MicroUSB, and it is compatible with USB1.1 and USB2.0, especially suitable for high-speed or higher-speed data transmission. The USB Type-C interface standard is one of the USB3.1 standards. The Type-C interface has four pairs of differential signal lines, two pairs of uplink/downlink, full-duplex communication, and supports USB male plug double-sided insertion.

In addition, the USB Type-C interface also supports converting the USB Type-C cable into Display Port (DP) alternate mode, that is, it can convert some or all of the differential signal channels in the USB Type-C signal line into DP signals channel, which enables the handheld device installed with the Type-C interface to realize high-speed data transmission and video output through a USB Type-C interface in this embodiment.

Based on this, a preferred application scenario of the handheld device of this embodiment is the scenario of playing mobile games. For example, the user connects the handheld device to a smart TV through the USB Type-C interface of the handheld device, and displays the game on the smart TV screen. Interface, and connect an external device, such as a gamepad, through another USB interface (can be a non-USB Type-C interface) on the handheld device. This greatly improves the user experience, and if the existing handheld device is used, there is only one USB interface, and the user may not be able to connect to a smart TV or a gamepad, so the user's experience is not good.

It should be noted that the USB female connector in the embodiment of the present invention can adopt the USB connector products in the prior art, and there is no limitation on the structure of the USB female connector. And the installation position of the USB female connector on the handheld device is not specifically limited, for example, it can be arranged at the side end of the handheld device or at the bottom end of the handheld device.

In summary, the technical solution of the present utility model is provided with two or more USB female connectors on the handheld device, and the two USB female connectors are connected to the micro control unit of the handheld device, and according to the micro The control command of the control unit interacts with the connected peripherals to realize the simultaneous operation of data transmission and charging, and it can realize the simultaneous connection of two external devices for use with handheld devices, which meets the needs of users and improves the User experience.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. And the use of the nouns first and second in the specification does not indicate any order, and these nouns can be interpreted as names.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. All modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model are included in the protection scope of the present utility model.
