Detailed Description

In order to make the technical field person understand the scheme of the present invention better, the following will combine the drawings in the embodiments of the present invention to clearly and completely describe the technical scheme in the embodiments of the present invention. It is to be understood that the embodiments described are merely exemplary of the invention, and that no limitations are intended to the details of construction or design herein shown. The present invention may be embodied in many different forms and is not limited to the embodiments described herein, which are provided for the purpose of providing a more thorough understanding of the present disclosure.

Referring to fig. 1-3, the automobile controller key structure with high waterproof and dustproof performance comprises an upper cover plate 1, wherein an assembly groove 5 for installing a key is formed in the upper cover plate 1, the key comprises a key body 2 and a key cap 3 assembled at the top end of the key body 2, and the assembly mode of each component of the key can adopt conventional riveting, screwing, buckling connection or interference fit and is selected according to actual requirements; the edge of the assembly groove 5 is convexly provided with a blocking bone 4, the inner side of the assembly groove 5 is further provided with a guide groove 6, a guide rib 7 is arranged at a position, corresponding to the guide groove 6, of the key body 2, the guide rib 7 is assembled in the guide groove 6 in a sliding mode, the bottom of the key body 2 is connected with a membrane switch and a PCB sub-assembly, key control is achieved by pressing the key cap 3 and moving the key body 2 up and down, the blocking bone 4 can prevent partial dust and water drops from flowing into the matching position of the key body 2 and the assembly groove 5, and when dust and water drops enter the controller along the gap between the upper cover and the keys, the dust and the water drops fall outside the blocking bone 4 and are blocked by the blocking bone 4.
