Description
Technical Field
[0001] This utility model relates to the field of automotive switch technology, and in particular to an automotive switch structure. Background Technology
[0002] As an indispensable means of transportation in modern cities, cars have entered thousands of households. With the gradual maturation of automotive-related technologies, people's requirements for cars are no longer limited to transportation. They have put forward higher requirements for comfort, convenience, and safety, and their requirements for the interior appearance of cars are also getting higher and higher. For example, car interior switches will integrate multiple function switches together.
[0003] Existing automotive switches include a base, a circuit board, a cover, and several buttons. The circuit board is located inside the base, and the buttons are located on the cover and can slide relative to the cover to trigger the switch on the circuit board, thereby achieving the corresponding function. Figure 1 As shown, area A of the cover is provided with button a, button b and panel. The panel is fixedly installed. The existing buttons require gaps around them to achieve the pressing function. Therefore, there are gaps between button a, button b and panel 100, and there are also gaps between button a and button b. This button structure is outdated, resulting in a large number of parts and poor aesthetics of the car switch, which does not meet customer needs. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects of the prior art by providing an automotive switch structure with an integrated operating component, reducing the number of parts. The operating component is also provided with an elastic deformation zone to reduce gaps and make it more aesthetically pleasing.
[0005] The technical solution of this utility model is as follows: A car switch structure includes a base, a circuit board, and a cover. The circuit board is disposed inside the base, and the cover is detachably disposed on the base. The cover has at least one operating area, and the operating area has a first operating component that can slide axially relative to the cover. The circuit board has a first switch and a first LED light corresponding to the position of the first operating component. The base has a first light guide channel corresponding to the position of the first LED light. The first operating component includes an integrally formed mounting part, a connecting part, a first pressing part, and a second pressing part. The mounting part is mounted on the base on both sides through connecting shafts. The first pressing part and the second pressing part are disposed at one end of the mounting part and are integrally disposed with the mounting part through the connecting part. There is a gap between the first pressing part and the second pressing part. When the pressing part is pressed down, the connecting part can elastically deform relative to the mounting part. The base has a movable space for the elastic deformation of the connecting part.
[0006] By adopting the above technical solution, the first operating component is integrally formed, and the mounting part at the rear end of the first operating component is fixed on the base. The connecting part can elastically deform relative to the mounting part, so that there is no need to set gaps between the pressing part and the connecting part. The pressing part can also be pressed down and spring back to reset. This can reduce gaps on the operating component and reduce the number of parts, making the overall switch structure more beautiful. At the same time, it can also reduce mold costs and save processing costs.

When the pressing part is pressed down, the connecting part 42 can elastically deform relative to the mounting part 41. The base 1 has a movable space for the elastic deformation of the connecting part 42. The first operating member 4 is integrally formed. The mounting part 41 at the rear end of the first operating member 4 is fixed on the base 1.

The second operating component 6 can swing relative to the base 1 to realize different functions. Triggering different second switches 23 can light up different second LED lights 24, and the current operation is indicated by the second LED lights 24.
[0027] The base 1 is also provided with a waterproof cover 7, which covers the circuit board 2. The waterproof cover 7 is provided with elastic protrusions 71 and through grooves 72.
