The embodiment of the invention provides a connecting mechanism, which comprises: a main body 20 and a detachable member 10 detachably connected to the main body 20.

The main body 20 includes a housing 21 and a connection assembly disposed in the housing 21, and the housing 21 is provided with a plugging hole 22 for plugging the detachable member 10.

The connection assembly includes a sliding member 30, the sliding member 30 is slidably connected to the housing 21, and the sliding member 30 is provided with an access hole 31 and an oblong hole 32 penetrating the access hole 31.

The detachable member 10 includes a plug member.

The sliding member 30 slides from the first position to the second position, the access hole 31 is opposite to the insertion hole 22, and the insertion member of the detachable member 10 protrudes into the access hole 31 through the insertion hole 22.

The sliding member 30 is slid from the second position to the first position, and the plug of the detachable member 10 enters the oblong hole 32 from the access hole 31, so that the sliding member 30 locks the detachable member 10 through the oblong hole 32.

According to the technical scheme provided by the embodiment of the invention, the detachable piece 10 and the main body 20 are disassembled and assembled through the operation of the sliding part 30. The mounting process as described above, the process of removing the detachable member 10 from the main body 20 is similar to the mounting process. The sliding part 30 is slid from the first position to the second position, the plug-in piece of the detachable piece 10 enters the access hole 31 from the oblong hole 32, the access hole 31 is opposite to the plug-in hole 22, and the plug-in piece of the detachable piece 10 is pulled out, so that the detachment of the detachable piece 10 from the main body 20 is completed. By operating the sliding member 30, the detachable member 10 can be flexibly replaced on the main body 20, and the operation is simple so as to satisfy different wearing requirements.

The following describes the connection mechanism provided in the embodiment of the present invention in further detail.

Referring to fig. 3 and 4, the sliding member 30 is provided with a spring 34 having a protrusion 33. The housing 21 is provided with a locking groove 23 and a loosening groove 24. The sliding component 30 slides from the first position to the second position, and the sliding component 30 drives the elastic sheet 34 to extend into the loosening groove 24 through the protruding structure 33. The sliding component 30 slides from the second position to the first position, the sliding component 30 drives the elastic sheet 34 to extend into the locking groove 23 through the protruding structure 33, and the sliding component 30 can be limited to move through the locking groove 23. The state that the elastic sheet 34 enters the locking groove 23 through the protruding structure 33 can be seen in fig. 5.

By the protruding structure 33 on the elastic sheet 34 entering the locking groove 23 and the loosening groove 24 respectively, it can be said that the sliding component 30 is locked at the first position or the second position, the sliding component 30 is prevented from moving back and forth, the connection stability between the detachable piece 10 and the main body 20 is affected, and meanwhile, a prompting effect is also achieved, for example, when the protruding structure 33 of the elastic sheet 34 enters or leaves the locking groove 23 or the loosening groove 24, a click sound is generated, and a user also feels a click feeling when pushing the sliding component 30, which means that the elastic sheet 34 of the sliding component 30 has entered/exited the locking groove 23/the loosening groove 24 through the protruding structure 33. After the protruding structure 33 of the spring plate 34 enters the locking groove 23/loosening groove 24, the locking groove 23/loosening groove 24 can limit the protruding structure 33 to move, and the protruding structure 33 cannot be separated from the locking groove 23/loosening groove 24 under the action of external force. Meanwhile, in order to ensure that the protruding structure 33 of the elastic sheet 34 can smoothly enter/leave the locking groove 23/loosening groove 24, the friction force between the protruding structure 33 and the locking groove 23/loosening groove 24 is reduced, and the contact surface of the locking groove 23/loosening groove 24 and the protruding structure 33 is a smooth curved surface.

In the embodiment of the present invention, after the detachable member 10 is connected to the main body 20, electrical connection can be further achieved. One implementation, referring to fig. 2, the connection assembly further includes an electrical connector 40, the electrical connector 40 being located between the sliding member 30 and the housing 21. The plug-in connector of the detachable member 10 is electrically conductive, and when the plug-in connector of the detachable member 10 is inserted into the access hole 31 through the plug-in hole 22, it is connected with the electrical connector 40 so as to electrically connect the detachable member 10 with the main body 20. Specifically, two hole-shaped electric connection parts are provided on the electric connector 40, the exposed copper is attached to the surface of the contact part of the electric connection parts, and the two electric connection parts are respectively connected with the positive and negative electrodes of the electric signal. The surface of the plug of the detachable member 10 is plated with metal, such as copper plating, which can make the plug of the detachable member 10 more wear-resistant, less prone to rust and can enhance electrical conductivity. The plug-in connector of the detachable piece 10 is contacted and connected with the electric connection part when passing through the electric connection part. In this way, positive and negative signals from the body 20 can be transmitted to the detachable member 10. The plug connector of the detachable piece 10 is electrically conductive in a mode of directly contacting with the exposed copper of the electric connection part, so that electric connection parts can be saved, and the design space is reduced.
