As shown in fig. 1 to 12, the present application provides a synchronous function, including: a housing 1, a driving member and a driven member; the side wall of the shell 1 is provided with a plurality of through holes 11; the driving part is rotatably fixed on the shell 1; the driving piece can rotate along a first direction and a second direction, and the first direction is opposite to the second direction; the driven component is positioned in the shell 1 and comprises at least two driven pieces, and each driven piece is assembled on the driving piece; the follower is provided with functional parts 62 which are arranged opposite to the through holes 11 one by one; when the driving member rotates along the first direction, each driven member can be driven to move to the first position, and the functional part 62 is exposed out of the casing 1 through the through hole 11; when the driving member rotates in the second direction, each driven member can be driven to move to the second position, so that the functional portion 62 is hidden in the housing 1.

Specifically, in the present embodiment, by at least two followers assembled on the driving member, the driving member can simultaneously drive the plurality of followers to move to the first position along the predetermined direction when rotating along the first direction (refer to fig. 4), at this time, the functional portion 62 located on each follower is exposed from the through hole 11 of the housing 1 to the housing 1, so as to achieve the connection or action (which can be understood as the working state) with the external components, and achieve the purpose of achieving the plurality of functions in one operation step. When the driving member rotates along the second direction (refer to fig. 7), the driving member can simultaneously drive the driven members to move to the second position along the predetermined direction, and at this time, the kinetic energy portions on the driven members can retract from the through holes 11 of the housing 1 into the housing 1, so as to achieve the purpose of hiding, save the arrangement space outside the housing 1, and protect the functional portion 62 from being damaged in the non-working state.

In the above structure, the first position or the second position of each follower is relative to the first position, that is, the first position of each follower may be a different position, and the second position of each follower may be a different position, referring to fig. 4 and 7. The specific orientations of the first position and the second position can be designed according to the connection requirement of the synchronous functional piece and the external part.

Further, in the above-described structure, the driving relationship between the driving member and the driven member may be realized by a mechanical structure such as a gear transmission or the like, referring to fig. 2, or may be realized in an electronically controlled manner.

The rack structure 6 is used as a driven piece, and the transmission teeth 61 meshed with the gear structure 4 are used for realizing the movement of the rack structure 6, so that the other end of the rack structure 6, namely the functional part 62, is driven to extend out of the shell 1 or retract into the shell 1. The gear transmission form is high in reliability, the transmission ratio can be set according to actual requirements, the moving stroke and distance of the functional part 62 can be controlled conveniently, and the accuracy of the function part 62 and external parts is improved.

If the arrangement positions of the components connected or acting externally to the functional parts 62 are not uniformly arranged, the functional parts 62 can be arranged according to the positions of the components by adjusting the lengths of the parts at the bending positions, thereby improving the flexibility of the design of the synchronous functional parts.

Optionally, a limiting groove 2 is further arranged in the shell 1, and the number and the shape of the limiting groove 2 and the shape of the rack structure 6 are mutually matched; the rack structures 6 are in one-to-one correspondence and movably arranged in the limiting grooves 2, and the limiting grooves 2 are used for guiding movement of the rack structures 6.
