[0002] For plug-and-play devices, such as plugs and sockets, some portable electronic products use locking mechanisms to improve connection reliability. These locking mechanisms in portable electronic products typically work by pushing open the latches and automatically locking them upon insertion, and then pressing them open to remove the plug. However, portable electronic products are generally not very large, and their plug-and-play mechanisms are usually quite small, such as the sockets and plugs on VR glasses. In such cases, the two latches may not coordinate well, making it difficult to ensure they disengage simultaneously, resulting in a poor user experience when removing the plug. Utility Model Content

[0023] Referring to the accompanying drawings, this utility model provides a locking and unlocking latch for use in plug-in connection devices on portable electronic devices, such as sockets on portable electronic devices, to lock the inserted plug. The portable electronic device is, for example, VR glasses.

[0024] The latch includes a left latch 1 and a right latch 2, with a return spring 3 between the left latch 1 and the right latch 2. The left latch and the right latch 2 are respectively provided with hooks 10 and 20, and the counterpart of the hook can be a hole or a slot (in this embodiment, the counterpart is provided on the plug that mates with the socket). The left latch 1 and the right latch 2 are also respectively provided with action parts 101 and 201 that accept pressure to open the hooks 10 and 20 of the left latch 1 and the right latch 2. The action parts can be the chamfered front end face of the hook. A synchronous reverse movement connecting mechanism is provided between the left latch 1 and the right latch 2, so that the left latch 1 and the right latch 2 can move synchronously in opposite directions.

[0025] The left buckle 1 and the right buckle 2 are also provided with pressing parts 11 and 21 respectively for operating the left buckle 1 and the right buckle 2 to unlock.

[0026] The left latch 1 and right latch 2 also have horizontal portions 12 and 22, respectively. The hooks 10 and 20 and the pressing parts 11 and 21 are located at both ends of the horizontal portions 12 and 22, respectively, so that the pressing part 11 of the left latch 1 is located on the right side of the latch, and the pressing part 11 of the right latch 2 is located on the left side of the latch. The horizontal portions 12 and 22 can be used to connect the synchronous reverse motion connecting mechanism, and the sides of the horizontal portions 12 and 22 can be fully utilized to connect the synchronous reverse motion connecting mechanism, which improves the applicability in the confined space of portable electronic products while ensuring structural strength. In addition, the spring 3 can also be located between the horizontal portions 12 and 22, and the horizontal portions 12 and 22 are respectively provided with spring connecting seats 121 and 221.

[0027] The horizontal portions 12 and 22 of the left latch 1 and right latch 2 are stacked vertically, and this stacking relationship can be used to set a guide engagement structure for horizontal relative sliding between them. In this embodiment, the lower horizontal portion 12 is provided with a guide rail 14, and the upper horizontal portion 22 is provided with a guide groove that mates with the guide rail 14.

[0028] The latch is provided with a mounting base 4 and a cover plate 5. The cover plate 5 is provided with a through hole 51. The through hole 51 can make way for the upper structure in the synchronous reverse motion connecting mechanism on the upper horizontal part 22, so that this upper and lower overlapping relationship can make a new contribution to the structural compactness.

[0029] The cover plate 5 and the mounting base 4 can be connected by screws. The horizontal portions 12 and 22 of the left buckle 1 and the right buckle 2 are located between the cover plate 5 and the mounting base 4. The left buckle 1 and the right buckle 2 are also provided with vertical portions 13 and 23. The vertical portion 13 of the left buckle 1 is connected to its horizontal portion 12, and the vertical portion 23 of the right buckle 2 is connected to its horizontal portion 22. The vertical portions 13 and 23 are located outside the mounting base 4. The hooks 10 and 20 are located at the ends of the vertical portions 13 and 23. Thus, the hooks 10 and 20 are located below the mounting base 4. The mounting base 4 can limit the resetting of the left buckle 1 and the right buckle 2. In addition, the mounting base 4 can be provided with a guide groove 41 for the horizontal sliding of the horizontal portion 12 located below. Combined with the guide of the horizontal portion 12 to the horizontal portion 22, a superimposed guide system is formed, which saves more space.

[0030] This embodiment provides a synchronous reverse motion connection mechanism with a simpler structure that better utilizes the compact structure of this utility model. It includes a first toothed plate 61 and a second toothed plate 62, with a gear 63 positioned between them. The first toothed plate 61 and the second toothed plate 62 are respectively connected to the transverse portion 12 of the left latch 1 and the transverse portion 22 of the right latch 2. The mounting base 4 has an upwardly opening gear shaft mounting groove 42 for inserting a gear shaft 64 from above. The gear shaft 64 is fixed to the gear shaft mounting groove 42 by the cover plate 5.

[0031] In addition, cam mechanisms can also be used for synchronous reverse motion connection mechanisms.
