The solutions of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

In the following description, for purposes of illustration rather than limitation, specific details, such as specific system architectures, interfaces, and techniques, are set forth in order to provide a thorough understanding of the present application.

In addition, the character "/" in this article generally indicates that the contextual objects are an "or" relationship. In addition, "many" herein means two or more than two. In addition, the term "at least one" herein means any one of a variety or any combination of at least two of the more, for example, including at least one of A, B, and C, which may mean including from A, Any one or more elements selected from the set formed by B and C.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of the first structure of an embodiment of the locking mechanism of the present application. Specifically, as shown in FIG. 1 , the locking mechanism 10 includes a first component 100 , a second component 200 and a locking member 300 .

Wherein, the first component 100 includes an accommodating chamber 110 having an opening. The locking member 300 is used to move between a first position and a second position in the accommodating cavity 110 .

When the locking member 300 is at the first position, the locking member 300 can lock the second assembly 200 protruding from the opening into the accommodating cavity 110 at a preset position. And, when the locking member 300 is in the second position, the locking member 300 can unlock the second component 200 so that the second component 200 can move out of the accommodating cavity 110 from the opening.

Specifically, when the second assembly 200 extends into the accommodating chamber 110 from the opening, the second assembly drives the locking member 300 to move from the first position toward the second position, so that the second assembly 200 can be inserted into the accommodating chamber 110 . And when the second assembly 200 reaches the preset position of the accommodating cavity 110 , the locking member 300 turns to move toward the first position, and when the locking member 300 returns to the first position, the locking member 300 locks the second assembly 200 .

Wherein, the preset position may be a position where the second component 200 can no longer drive the locking member 300 to move from the first position to the second position, so that the locking member 300 turns to move toward the first position. In some disclosed embodiments, the preset position may be a position where the second component 200 cannot move toward the bottom of the accommodating cavity 110 due to structural factors between the first component 100 and the second component 200 . For example, the preset position may be a position where the top of the second component 200 abuts against the bottom of the accommodating cavity 110 . It cannot move toward the bottom of the accommodation cavity 110 any more. Of course, the preset position can also be that other positions of the second component 200 abut against other positions at the opening of the accommodating cavity 110 (for example, the structural position at the opening), so that the second component 200 can no longer drive the locking member 300 from The first position moves toward the second position.

Wherein, locking means that the second component 200 cannot be moved out of the accommodating cavity 110 of the first component 100 without external force.

And, in the locked state, when the second assembly 200 needs to be removed from the accommodating chamber 110 of the first assembly 100, the locking member 300 moves from the first position to the second position, so that the second assembly 200 can be removed from the opening of the accommodating chamber 110 move out. Specifically, when the locking member 300 is driven to the second position, the locking member 300 can contact the locking of the second component 200 so that the second component 200 can move out of the accommodating cavity 110 from the opening.

In the above scheme, the locking and unlocking of the first assembly 100 and the second assembly 200 is realized by changing the position of the locking member 300, compared with adding a latch in the first assembly 100, the connection between the first assembly 100 and the second assembly 200 is realized. In terms of locking, the unlocking of the first assembly 100 and the second assembly 200 is more convenient.

In some disclosed embodiments, the first component 100 is a knob cap, and the second component 200 is a knob switch. Among them, the rotary switch can be used to connect with the device. Wherein, when the knob switch is locked in the knob cap, the knob switch can be driven to rotate by rotating the knob cap, thereby controlling the state of the device. In some application scenarios, the rotary switch is connected to the walkie-talkie. Specifically, rotating the rotary switch can control the intercom to switch channels or adjust the playback volume and so on. For example, the rotary switch is connected to the circuit for switching channels, and the switching of the intercom channel can be controlled by the rotation of the rotary switch. Or, the rotary switch is connected with the sound adjustment circuit, then the switching of the intercom sound can be controlled by the rotation of the rotary switch. In some other disclosed embodiments, the rotary switch can also be connected with equipment such as speakers and fans.

Wherein, the orthographic projection of the inner wall and/or outer wall of the accommodating cavity 110 on a plane parallel to the bottom of the accommodating cavity 110 is a circle. In some specific application scenarios, when the first component 100 is a knob cap, threads are engraved on the outer wall of the accommodating cavity 110 . By engraving threads on the outer wall of the accommodating cavity 110 , the frictional force of the outer wall can be increased, so as to reduce the situation of relative sliding when the user twists the knob cap. Of course, in some disclosed embodiments, due to production and processing errors, there are some protrusions or depressions on the inner wall or the outer wall, or the projection is an ellipse, which is fine.

Further, the number of concave structures is 2, and each concave structure may have multiple forms, for example, the concave surface may be a hemispherical surface or a curved surface with other proportions, or may be composed of a plane with at least one slope and connecting slopes. Wherein, when the concave surface of the concave structure is a hemispherical surface, in order to cooperate with the concave structure, the convex surface of the convex structure may also be correspondingly set as a hemispherical surface. Wherein, when the concave surface of the concave structure is formed by at least one slope, the convex surface of the convex structure can be provided with at least one slope correspondingly, so that when the first locking part 211 cooperates with the second locking part 310, the first locking part 211 The slope abuts against the slope of the second locking portion 310 .
