DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] See Figures 1 to 4 As shown, an interior light switch assembly includes a base 1 and a button 2, a return spring is arranged between the button and the base, and a PCB board with a button is arranged in the base. In this embodiment, the return spring and the PCB board are conventional structures of the prior art, so they are not described in detail.

[0030] The button is matched with the button position, and a button cavity 3 is arranged in the middle of the top surface of the base, and a button channel 4 is opened at the bottom of the button cavity; the bottom wall of the button cavity is integrally formed with a limiting convex edge 5, and the limiting convex edge is located at the edge of the top surface of the button channel; in this embodiment, the button channel is square in shape, and can specifically be rectangular or square.

[0031] The inner wall of the key channel is provided with a plurality of guide vertical grooves 6; the lower part of the inner wall of the key channel is formed with a plurality of limiting protrusions 7; in this embodiment, the top of the inner wall of the guide vertical groove is an inclined introduction surface 12, and the opening of the guide vertical groove is larger than the width of the guide vertical groove. The guide vertical groove is located on the inner wall of the key channel and is open at the top, mainly used for the guide convex strip of the key to insert and limit, to prevent tilting, displacement or falling off; in actual application, the outer wall of the key is formed with a guide convex strip 8 that matches the guide vertical groove; the lower part of the outer wall of the key is provided with a vertical limiting groove 9; during installation, the guide convex strip can be raised and lowered in the guide vertical groove; the limiting protrusion can be raised and lowered in the vertical limiting groove, and the limiting protrusion is limited by the top wall and bottom wall of the vertical limiting groove when it is raised and lowered in the vertical limiting groove. In this embodiment, the base and the key are both insulating plastic structures. During installation, through the deformable properties of the plastic, when the external force is large, the limiting protrusion will squeeze the inner wall of the guide vertical groove and move downward into the vertical limiting groove, and then the plastic will deform and reset, and a practical snap-on connection can not only improve the stability and reliability of the connection, but also is not easy to loosen.

[0032] In actual application, the bottom edge of the button is provided with a position-avoiding groove 10 that matches the position-limiting convex edge; an n-shaped sealing strip is provided in the position-avoiding groove; the position-limiting convex edge can be raised and lowered in the recessed area of ​​the n-shaped sealing strip. Through the above structure, the sealing between the button and the position-limiting convex edge can be improved by providing the n-shaped sealing strip, and at the same time, the width of the recessed area of ​​the n-shaped sealing strip is greater than the thickness of the position-limiting convex edge, so that the n-shaped sealing strip does not affect the lifting and lowering action of the position-limiting convex strip in the position-avoiding groove, and the practicality is strong.

[0033] In actual application, there are four vertical guide grooves respectively arranged in the middle of the four sides of the key channel. The outer wall of the base is integrally formed with a mounting buckle 11 for mounting on the vehicle body. The height of the vertical limit groove is twice the height of the limit protrusion. This embodiment improves the convenience of bottom installation and is highly practical.

[0034] The utility model has positive effects: the structure of the utility model is reasonably arranged, a plurality of guide vertical grooves are arranged on the inner wall of the key channel, and a plurality of guide convex strips are arranged on the outer wall of the key. The plurality of guide convex strips cooperate with the guide vertical grooves to ensure stability during operation and prevent loosening or displacement. At the same time, the vertical limit groove cooperates with the limit convex block to limit the position after pressing, which is beneficial to improving the stability and reliability of use, and is also convenient for disassembly, assembly and maintenance operations, and has strong applicability and good practicality.

[0035] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
