[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1-4 As shown, this embodiment discloses a car tailgate switch, which includes a shell 1 with a cavity 3 and a button 2 sealed with the shell 1 and used to close the cavity 3. The button 2 is rotatably connected to the shell 1, and the connection structure between the button 2 and the shell 1 is the same as the structure disclosed in Patent No. CN201721286855.0; this application is an improvement made on the basis of it.

[0018] A touch switch 4 cooperating with the button 2 is arranged in the cavity 3. When the user presses the button 2, the button 2 triggers the touch switch 4, thereby opening the trunk of the car. When the user releases the button 2, the button 2 will automatically reset.

[0019] like Figure 2-3 As shown, the button 2 includes a fixed portion 21 and a pressing portion 22. The fixed portion 21 is connected to the housing 1 through an elastic seal 23. The edge of the elastic seal 23 covers the edge of the housing 1 and is snap-fitted with the housing 1. The fixed portion 21 and the elastic seal 23 are integrally formed with rubber. A connecting port 24 is provided in the middle of the fixed portion 21. The pressing portion 22 is rotatably connected to the concave cavity 3 of the housing 1 through the connecting port 24. At the same time, the pressing portion 22 and the fixed portion 21 are sealed and connected through a connecting structure and the connecting port 24 is closed.

[0020] like Figure 3-4As shown, the connection structure includes a card slot 25 arranged on the outer surface of the fixing portion 21 and around the edge of the connecting port 24, and a plug plate 26 arranged on the bottom edge of the pressing portion 22 and plugged with the card slot 25; two groups of limiting strips 27 are symmetrically arranged on both sides of the inner wall of the card slot 25, and the two groups of limiting strips 27 are vertically distributed on the inner wall of the card slot 25, and a limiting groove 28 is formed between the two adjacent groups of limiting strips 27, and connecting strips 29 that are plugged with the limiting groove 28 are arranged on both sides of the plug plate 26 relative to the card slot 25. When the staff inserts the plug plate 26 into the card slot 25, the limiting strip 27 can be deformed and bent due to its rubber material, so the limiting strip 27 will be squeezed and deformed under the action of the connecting strip 29 made of plastic, so that the connecting strip 29 can smoothly enter the limiting groove 28 to achieve plugging with the limiting groove 28.

[0021] At the same time, since the side of the limit strip 27 relative to the plug plate 26 is provided with a guide angle 7 inclined from top to bottom in the direction of the plug plate 26, the connecting strip 29 can be inserted more smoothly, and when it is pulled out, the limit strip 27 is difficult to be pulled out due to the absence of the guide angle 7, so that the connection between the pressing portion 22 and the fixing portion 21 is more stable and firm; at the same time, a filling groove 5 connecting the two limit grooves 28 is provided in the card slot 25, and a casting hole 6 connecting the filling groove 5 with the outside is provided on the fixing portion 21. When the staff connects the pressing portion 22 with the fixing portion After the connection is made between the plug plate 26 and the card slot 25, the glue can be filled into the limiting groove 28 through the pouring hole 6 and filled into the card slot 25 through the filling groove 5, so as to realize the bonding and fixing between the plug plate 26 and the card slot 25, thereby improving the connection strength and the sealing effect, and ensuring that the connection between the connecting part and the fixing part 21 will not be cracked or damaged after the pressing part 22 is subjected to stress for a long time; and filling the glue into the card slot 25 can realize the sealing protection of the glue, avoid the glue being exposed to the outside to absorb moisture or being exposed to the sun for a long time, which may reduce the viscosity, and improve the service life of the glue.

[0022] The staff of the pouring hole 6 can seal the pouring hole 6 by melting the rubber strip.

[0023] The width of the limit strip 27 gradually narrows from the bottom of the slot 25 to the outside; the width of the connecting strips 29 gradually widens from the bottom of the slot 25 to the outside, so that when the plug board 26 is inserted into the slot 25, the connecting strip 29 will only contact the matching limit strip 27, and the obstruction of the limit strip 27 only needs to be overcome once, thereby making the insertion process of the plug board 26 more labor-saving.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
