[0046] To fully understand this utility model, the following specific embodiments, in conjunction with the accompanying drawings, provide a detailed description. Those skilled in the art can understand the purpose, features, and effects of this utility model from the content disclosed in this specification. It should be noted that this utility model can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of this utility model. The following embodiments will further describe the relevant technical content of this utility model in detail, but the disclosed content is not intended to limit the scope of the patent application of this utility model. The explanation is as follows:

[0047] like Figure 1 and Figure 2As shown, the dual-axis pivot 100 with locking function in this embodiment of the present invention includes a first rotating member 1, a second rotating member 2, a driving member 3 and a slider member 4.

[0048] The first rotating component 1 includes a first rotating shaft 11 and a first rotating arm 12. The second rotating component 2 is arranged parallel to the first rotating component 1 and includes a second rotating shaft 21 and a second rotating arm 22. The first rotating component 1 and the second rotating component 2 are generally symmetrical in structure. The first rotating arm 12 and the second rotating arm 22 are respectively mounted on the base and the top cover of the device (e.g., a laptop or a foldable mobile phone). When the user opens and closes the base and the top cover relative to each other, the first rotating arm 12 and the second rotating arm 22 mounted on the base and the top cover respectively also rotate relative to each other.

[0049] The following explains how to make the other rotating arm rotate synchronously when only one of the first rotating arm 12 and the second rotating arm 22 is rotated.

[0050] like Figure 3B , Figure 4B , Figure 5B As shown, 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.

[0051] The driving component 3 is disposed between the first rotating shaft 11 and the second rotating shaft 21 and engages with the first thread 111 and the second thread 211. Specifically, in this embodiment, the driving component 3 is in the form of an idler wheel 31, the periphery of which has a tooth 311 that engages with the first thread 111 and the second thread 211. Rotation of either the first rotating arm 12 or the second rotating arm 22 directly drives the first rotating shaft 11 /

[0052] The second rotating shaft 21 rotates around its axis. When either the first rotating shaft 11 or the second rotating shaft 21 rotates, it drives the component 3 (idler wheel 31) to rotate via the first thread 111 or the second thread 211. This component 3 (idler wheel 31) then drives the other of the first rotating shaft 11 and the second rotating shaft 21 to rotate. Therefore, by moving either the first rotating arm 12 or the second rotating arm 22, the other will also rotate accordingly.

[0053] To increase the locking force at a specific angle, the slider component 4 includes an elastic element 42 and a pushing slider 41. The elastic element 42 is, for example, a spring or other element capable of storing elastic potential energy; in this embodiment, it is a compression spring. The elastic element 42 abuts against the pushing slider 41, and the preload of the elastic element continuously pushes the pushing slider 41 toward the driving member 3. Correspondingly, the driving member 3 also has a receiving portion 313, which is provided in the notch of the toothed portion 311 and recessed inward (towards the 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 and interferes with the driving member 3.

[0054] like Figure 3A and Figure 3B As shown, in this embodiment, when the angle between the first rotating arm 12 and the second rotating arm 22 is 0 degrees (base and top cover closed), the receiving part 313 is directly opposite the push slider 41. Therefore, the push slider 41 enters the receiving part 313, causing the member 3 to interfere. In this state, a greater force is required to push the push slider 41 out of the receiving part 313. Therefore, at 0 degrees, a greater locking force can be provided compared to other angles.

[0055] like Figure 4A and Figure 4B As shown, when the external force overcomes the force applied by the push slider 41 and the elastic element 42, the receiving part 313 no longer faces the push slider 41, causing the component 3 to rotate smoothly.

[0056] like Figure 5A and Figure 5B As shown, from 90 degrees to 180 degrees, there was no interference between the push slider 41 and the receiving part 313.

[0057] In summary, by setting the position, range, and number of the receiving parts 313, the function of requiring more force to continue rotating at a specific angle can be achieved. For example, in this embodiment, the receiving parts 313 are positioned at a 0-degree angle corresponding to the two rotating arms, which prevents the device from opening unexpectedly. However, they can also be positioned at 90 degrees or 180 degrees to fix the device at a specific angle; or, multiple receiving parts 313 can be provided to provide locking force at different angles.

[0058] Furthermore, the receiving part 313 in this embodiment is shaped such that interference with the push slider 41 can be released by applying an external force in the same direction as the operation. However, the present invention is not limited to this; the receiving part may also be shaped such that it enters a locked state once interference occurs (it cannot be released by applying an external force in the same direction as the operation), and can only be released by disassembly or triggering a specific release mechanism.

[0059] Furthermore, in this embodiment, the dual-axis pivot 100 with locking function also includes a fixing frame 5, to which the first rotating shaft 11, the second rotating shaft 21, and the elastic element 42 abut. 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.

[0060] Furthermore, the slider component 4 also includes an adjusting screw 43, which is disposed on the fixed frame 5. The elastic element 42 indirectly abuts against the fixed frame 5 through the adjusting screw 43. In detail, one end of the elastic element 42 abuts against the push slider 41, and the other end abuts against the adjusting screw 43. By adjusting the position of the elastic element 42 on the fixed frame 5 along the axial direction of the first rotating shaft 11 and the second rotating shaft 21 through the adjusting screw 43, the degree of compression of the elastic element 42 can be changed, thereby adjusting the force exerted on the push slider 41.

[0061] Furthermore, in this embodiment, the driving member 3 is in the form of an idler wheel 31, and the receiving portion 313 is provided in the notch of the toothed portion 311 and is recessed inward from the periphery of the driving member 3. However, the present invention is not limited to this; the receiving portion 313 may be provided in other positions, and the driving member 3 may also be in other structural forms. Any mechanism that can transmit power from the first rotating shaft 11 to the second rotating shaft 21 can serve as the driving member 3.

[0062] Other examples Figure 1 and Figure 2 As shown, the driving component may further include a housing 32 to support the idler wheel 31.

[0063] Furthermore, in this embodiment, the first rotating member 1 further includes a first spring plate 13, which is sleeved on the first rotating shaft 11; the second rotating member 2 further includes a second spring plate 23, which is sleeved on the second rotating shaft 21. The first spring plate 13 and the second spring plate 23 can provide frictional force to maintain a specific angle during the rotation of the first rotating member 1 and the second rotating member 2.

It should be noted that all variations and substitutions equivalent to these examples should be considered within the scope of this utility model. Therefore, the protection scope of this utility model should be determined by the claims.
