Description

Technical Field

[0001] The utility model relates to the field of a control switch on a car, in particular to a door-controlled lock switch. Background Art

[0002] Door control lock switches are mainly used on car doors to control the locking and unlocking of car doors. During the use of existing general door control locks, the assembly quality and design are unreasonable. The buttons may become loose during the pressing process. In addition, the positioning of the switch during installation is unreliable, which affects the efficiency of assembly. At the same time, it will also cause the switch to become loose, making the operation feel extremely poor. The switch is basically exposed on the car door, and rain or liquid can easily enter the switch, affecting the physical properties of the circuit board in the switch, causing damage to the circuit board and the switch cannot be used. Therefore, a more optimized design of the switch is needed. Utility Model Content

[0014] The present invention is specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the protection scope of the present invention.

[0015] like Figure 1 — Figure 4As shown, this embodiment discloses a door-controlled lock switch, including a base 1, a circuit board 2, a socket 3, a shell 4 and a button assembly 5. The circuit board 2 is provided with an elastic contact corresponding to the button assembly 5, and the bottom of the button assembly 5 is close to the elastic contact. The circuit board 2 is covered with a rubber waterproof diaphragm 10. The circuit board 2 is connected to the socket 3 through a wire. The circuit board 2 is positioned on the base 1. The shell 4 is snap-fitted on the base 1 and covers the circuit board 2. The button assembly 5 includes a locking button 51 and an unlocking button 52. The structures of the locking button 51 and the unlocking button 52 are the same. The shell 4 is convexly provided with two square ring-shaped guide grooves 41, a locking button 51 is vertically guided and inserted into one of the guide grooves 41, and an unlocking button 52 is vertically guided and inserted into the other guide groove 41, a limiting square opening 6 is respectively provided on the locking button 51 and the unlocking button 52, a limiting convex point 410 is provided on the side wall of the guide groove 41, and the limiting square opening 6 is placed in the limiting convex point 410, and end covers 7 are respectively provided on the upper ends of the locking button 51 and the unlocking button 52, and the end covers 7 surround and cover the outer wall of the guide groove 41, and a positioning component 8 is also provided at one end of the housing 4.

[0016] The outer walls of the locking button 51 and the unlocking button 52 are respectively provided with three straight guide grooves 50 arranged along their heights, that is, the three straight guide grooves 50 are distributed on different side walls, and the inner wall of the guide through groove 41 is provided with guide convex strips 411 which correspond to and match the straight guide grooves 50 one by one, and the cross section of the guide convex strips 411 is "T" shaped, and the guide convex strips 411 are placed in the straight guide grooves 50. This structure can make the locking button 51 and the unlocking button 52 press and rebound more smoothly and compactly without looseness.

[0017] The positioning assembly 8 comprises a block-shaped boss 81, and a cylindrical positioning boss 82 is also provided on the upper end surface of the boss 81. The overall positioning can be achieved by plugging the structure with the installation position of the switch in a concave and convex manner.

[0018] The limiting square opening 6 is in the shape of a prism. With this structure, the limiting square opening 6 can be more conveniently slidably inserted into the limiting convex point 410 of the guide through groove 41 along its peripheral wall, making assembly more convenient.

[0019] By adopting the above technical scheme, after the door control lock switch is assembled, it can be positioned and matched with the installation position through the positioning component 8, which can effectively improve the overall positioning. The characteristics of the rubber waterproof diaphragm and the end cover 7 surrounding and covering the outer wall of the guide groove 41 can effectively improve the waterproof performance. At the same time, the locking button 51 and the unlocking button 52 are pressed and rebounded to guide reliably and stably, thus achieving a technical effect of good waterproofness and a more reasonable and reliable structure, ensuring that the pressing operation is more reliable.

[0020] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model.
