For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0032] In the first aspect, an embodiment of the present utility model provides a switch structure as Figures 1 to 3As shown in the figure, it includes a base 1, a circuit board 2, and a pressing frame 3. The circuit board 2 is installed on the upper part of the base 1. The upper surface of the circuit board 2 has a switch element 21, and the switch element 21 can adopt existing switch structures such as a micro switch or a tactile switch. The pressing frame 3 is arranged above the circuit board 2 and fixedly connected to the base 1, and the pressing frame 3 can play a role in resisting and limiting the circuit board 2. The circuit board 2 needs to be connected to an external circuit through a wire. In this embodiment, a notch 11 penetrating in the up and down direction is provided on the side edge of the base 1, and a retaining edge 31 protruding downward into the notch 11 is provided on the pressing frame 3. A wire passing hole A is formed inside the notch 11 on the inner side of the retaining edge 31. During assembly, the circuit board 2 is installed on the base 1, the wire connected to the circuit board 2 is placed into the notch 11, and then the pressing frame 3 is installed on the base 1. The retaining edge 31 on the pressing frame 3 extends into the outside of the notch 11, and the wire is limited in the wire passing hole A inside it by the retaining edge 31. This not only facilitates the threading of the wire, but also makes the assembly convenient, and the cooperation between the retaining edge 3 on the pressing frame 3 and the notch 11 on the base 1 also has an anti-mistake function to prevent the pressing frame 3 from being installed in the wrong direction.

[0033] As Figure 2 shown, an inner cavity 12 communicating with the notch is provided on the upper part of the base 1. The circuit board 2 is installed in the inner cavity 12. A support platform 13 for upwardly supporting the circuit board 2 is provided in the inner cavity 12. A gap B is formed below the circuit board 2 in the inner cavity 12. The existence of this gap B can not only be used to accommodate the electronic components on the bottom surface of the circuit board 2, but also for wire laying, and the wire can also pass through the gap B.

[0034] To enhance the dust-proof performance of the upper surface of the circuit board 2 and the switch element 21, a rubber sleeve 4 is also provided. The rubber sleeve 4 covers the upper part of the circuit board 2. The peripheral edge of the rubber sleeve 4 has a wrapping part 41 wrapped around the outer peripheral edge of the circuit board 2. The rubber sleeve 4 can be installed on the circuit board 2 by sleeving the wrapping part 41 with the outer peripheral edge of the circuit board 2, and the pressing frame 3 is pressed on the upper part of the wrapping part 41.

[0035] As Figure 2 shown, the rubber sleeve 4 is provided with an upward raised part 42. A cavity is formed inside the raised part 42, and the switch element 21 is located in the cavity. A relief hole 32 is formed at a position corresponding to the raised part 42 on the pressing frame 3, and the raised part 42 passes through the relief hole 32.

[0036] To facilitate pressing and triggering the switch element 21, a key cap 5 is sleeved on the raised part 42. The inner cavity shape of the key cap 5 matches the outer wall shape of the raised part 42, and the switch element 21 can be triggered by pressing the key cap 5.

[0037] In some embodiments, an anti-fooling structure is provided between the key cap 5 and the raised portion 42. The anti-fooling structure can indicate the installation direction of the key cap 5 to ensure that the installation angle of the key cap 5 is not deviated. Exemplarily, the anti-fooling structure includes a plug platform provided on the inner wall of the key cap 5 and a slot provided on the raised portion 42. When the key cap 5 is sleeved, the key cap 5 can be smoothly sleeved on the raised portion 42 only when the plug platform is aligned with the slot. On the contrary, the interference between the plug platform and the raised portion 42 can prevent the key cap 5 from being installed in place.

[0038] In some embodiments, a convex edge 51 protruding outward is provided on the peripheral edge of the bottom of the key cap 5. When installed, the key cap 5 is inserted into the key hole of the switch housing, and the convex edge 51 abuts against the inner edge of the key hole to limit the key cap 5 to prevent the key cap 5 from falling off.

[0039] In order to facilitate the assembly of the pressing frame 3 and the base 1, the pressing frame 3 is snap-connected to the base 1 through a snap structure. Exemplarily, the snap structure includes a snap hole provided on the side wall of the cavity 11 of the base 1 and a snap table provided on the outer edge of the pressing frame 3. The pressing block 3 is fixed inside the base 1 by snap-connecting the snap table and the snap hole; in actual operation, the positions of the snap table and the snap hole can also be interchanged.

[0040] In some embodiments, a fixing frame 14 is provided on the base 1, and the fixing frame 14 is fixed to a fixing component with screws to fixedly install the switch. As a variant, a buckle can also be provided on the base 1, and then the switch can be installed by snapping through the buckle.

[0041] In a second aspect, the present invention provides a vehicle handle switch, including the switch described in any of the above embodiments. The switch can be used for function switches such as a lighting switch, a warning switch, and a grip heating switch. Since the vehicle handle switch uses the switch structure in the above embodiments, the vehicle handle switch has all the advantages of the switch in the above embodiments, and details are not described herein.

[0042] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
