Detailed Description

For a thorough understanding of the present utility model, the present utility model will be described in detail with reference to the following specific examples, and the accompanying drawings. The objects, features and effects of the present utility model will be apparent to those skilled in the art from the disclosure of the present specification. It is to be understood that the utility model may be practiced or carried out in other embodiments and that various modifications and alterations may be made in the details of the description herein without departing from the spirit or scope of the utility model. The following embodiments will further illustrate the related art of the present utility model in detail, but the disclosure is not intended to limit the scope of the present utility model as claimed. The description is as follows:

As shown in fig. 1 and 2, the dual-axis hinge 100 with locking function according to the embodiment of the utility model includes a first rotating member 1, a second rotating member 2, a driving member 3 and a slider member 4.

The first rotating member 1 includes a first rotating shaft 11 and a first rotating arm 12, the second rotating member 2 is disposed parallel to the first rotating member 1, and the second rotating member 2 includes a second rotating shaft 21 and a second rotating arm 22. The first rotating member 1 and the second rotating member 2 are substantially symmetrical in structure. The first rotating arm 12 and the second rotating arm 22 are respectively disposed on a base and an upper cover of a device (such as a notebook computer or a folding mobile phone), and when the base and the upper cover are opened and closed by a user, the first rotating arm 12 and the second rotating arm 22 respectively disposed on the base and the upper cover also rotate relatively.

Next, it will be described how, when only one of the first and second rotating arms 12, 22 is rotated, the other is rotated in synchronization.

As shown in fig. 3B, 4B, and 5B, the surface of the first rotating shaft 11 is provided with a first thread 111, and one end of the first rotating arm 12 is connected to the first rotating shaft 11. The surface of the second rotating shaft 21 is provided with a second thread 211, and one end of the second rotating arm 22 is connected to the second rotating shaft 21.

The driving member 3 is disposed between the first rotating shaft 11 and the second rotating shaft 21 and engaged with the first thread 111 and the second thread 211. In detail, in the present embodiment, the driving member 3 is in the form of an idler 31, and a tooth portion 311 engaged with the first thread 111 and the second thread 211 is disposed on the periphery of the idler 31. The first rotating arm 12 and the second rotating arm 22 are rotated to directly drive the first rotating shaft 11 +

The second shaft 21 rotates around the axis, and the first shaft 11 and the second shaft 21 rotate through the first thread 111 or the second thread 211 to drive the member 3 (idler 31) to rotate, and the member 3 (idler 31) drives the other of the first shaft 11 and the second shaft 21 to rotate. Therefore, when one of the first pivot arm 12 and the second pivot arm 22 is pulled, the other is correspondingly rotated.

In order to increase the locking force under a specific angle, the slider member 4 includes an elastic element 42 and a pushing slider 41. The elastic element 42 is, for example, a spring or the like capable of storing elastic potential energy, and is a compression spring in this embodiment. The elastic element 42 abuts against the pushing slider 41, and the pushing slider 41 is continuously pushed toward the driving member 3 by the pre-compression of the elastic element. Correspondingly, the driving member 3 further has a receiving portion 313, and the receiving portion 313 is disposed in the notch of the tooth portion 311 and is recessed inward (rotation center) from the periphery of the driving member 3. When the driving member 3 rotates to a predetermined angle, the pushing slider 41 enters the receiving portion 313 from the periphery of the driving member 3 to interfere with the driving member 3.

As shown in fig. 3A and 3B, in the present embodiment, when the included angle between the first rotating arm 12 and the second rotating arm 22 is 0 degrees (the base and the upper cover are closed), the receiving portion 313 faces the pushing slider 41, so that the pushing slider 41 enters the receiving portion 313 to drive the component 3 to interfere. In this state, a larger force is required to push the pushing slider 41 out of the receiving portion 313, so that a larger locking force can be provided at 0 degrees than at other angles.

As shown in fig. 4A and 4B, when the external force overcomes the urging force of the pushing slider 41 and the elastic element 42, the receiving portion 313 no longer faces the pushing slider 41, and the driving member 3 rotates smoothly.

As shown in fig. 5A and 5B, the pushing slider 41 and the receiving portion 313 do not interfere at the stage from 90 degrees to 180 degrees.

In summary, the position, the range, and the number of the receiving portions 313 can be set to achieve the function that more force must be applied to continue the rotation at a specific angle. For example, in the present embodiment, the receiving portion 313 is located at a position corresponding to an angle of 0 degrees between the two rotating arms, so as to prevent the device from being opened unexpectedly. However, it may be provided at a position of 90 degrees or 180 degrees instead so that the device can be fixed at a specific angle, or a plurality of receiving portions 313 may be provided to provide locking force at different angles.

In addition, the receiving portion 313 of the present embodiment is shaped so as to be free from interference with the pushing slider 41 by increasing the external force in the same operation direction. However, the present invention is not limited thereto, and the receiving portion may be provided in a shape that can be released only by detaching or triggering a specific release mechanism when the receiving portion enters a locked state (cannot be released by increasing an external force in the same operation direction) upon occurrence of interference.

Further, in the present embodiment, the dual-axis hinge 100 with locking function further includes a fixing frame 5, and the first rotating shaft 11, the second rotating shaft 21 and the elastic element 42 are abutted against the fixing frame 5. The fixing frame 5 serves as an anchor point for fixing the first rotating shaft 11, the second rotating shaft 21 and the elastic element 42.

Further, the slider member 4 further includes an adjusting screw 43 disposed on the fixing frame 5, and the elastic element 42 is indirectly abutted to the fixing frame 5 through the adjusting screw 43. Specifically, one end of the elastic element 42 abuts against the pushing slider 41, and the other end abuts against the adjusting screw 43, and the adjusting screw 43 adjusts the position of the fixing frame 5 along the axial direction of the first shaft 11 and the second shaft 21, so that the compression degree of the elastic element 42 can be changed, and the stacking force of the pushing slider 41 can be adjusted.

Further, in the present embodiment, the driving member 3 is in the form of an idler 31, and the receiving portion 313 is disposed at the notch of the tooth portion 311 and is recessed inward from the periphery of the driving member 3. However, the present invention is not limited thereto, and the receiving portion 313 may be disposed at other positions, and the driving member 3 may be in other structures. Any mechanism that can be driven from the first shaft 11 to the second shaft 21 can be used as the driving member 3.

As shown in fig. 1 and 2, the driving member may further include a housing 32 for carrying the idler wheel 31.

Further, in the present embodiment, the first rotating member 1 further includes a first elastic piece 13 sleeved on the first rotating shaft 11, and the second rotating member 2 further includes a second elastic piece 23 sleeved on the second rotating shaft 21. The first spring plate 13 and the second spring plate 23 can provide friction force for maintaining a specific angle during the rotation of the first rotating member 1 and the second rotating member 2.

The present utility model has been disclosed in the foregoing with reference to examples, which, however, should be understood by those skilled in the art to be merely illustrative of the present utility model and should not be construed as limiting the scope of the present utility model. It should be noted that all changes and substitutions equivalent to the embodiment are intended to be included in the scope of the present utility model. Accordingly, the scope of the utility model is defined by the claims.
