In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0028] Embodiment 1:

[0029] This embodiment provides a waterproof door and window switch, including:

[0030] A housing 1, wherein a communicating accommodation cavity 5 is provided in the housing 1, and a positioning convex ring 6 is provided on the inner peripheral wall of the housing 1;

[0031] The elastic button 2 is arranged in the accommodating cavity 5. The bottom of the outer peripheral wall of the elastic button 2 is provided with a first convex ring 7 and a second convex ring 8 in sequence from top to bottom. A positioning ring groove 9 is formed between the first convex ring 7 and the second convex ring 8 and is clamped in the positioning convex ring 6. The bottom of the elastic button 2 is provided with an avoidance ring groove 10.

[0032] The base 3 is arranged at the bottom of the housing 1. A sealing convex ring 11 is arranged on the upper surface of the base 3. A receiving groove 12 is formed in the center of the sealing convex ring 11. A circuit board 13 is arranged in the receiving groove 12. The top of the sealing convex ring 11 abuts against the bottom of the second convex ring 8.

[0033] The switch assembly 4 is electrically connected to the upper surface of the circuit board 13 . The switch assembly 4 includes two first switches and two second switches facing away from the two first switches. The bottom of the elastic button 2 abuts against the upper surfaces of the two first switches and the two second switches.

[0034] In the present technical solution, the shell 1 and the base 3 may be made of plastic, and the shell 1 may be a cylindrical structure.

[0035] The elastic button 2 can be made of elastic silicone material, which has the advantages of being soft, wear-resistant, waterproof and anti-aging.

[0036] During installation, since the elastic button 2 is elastic, the elastic button 2 is first clamped on the positioning convex ring 6 on the housing 1 through the positioning ring groove 9 to be fixed, which can seal the inner wall of the housing 1 and the elastic button 2 to prevent liquid from penetrating into the receiving groove 12. The switch assembly 4 can be welded on the circuit board 13, and then the circuit board 13 welded with the switch assembly 4 is installed in the receiving groove 12 of the base 3, and then the base 3 is fixed to the bottom of the housing 1, so that the top of the sealing convex ring 11 contacts the bottom of the second convex ring 8, thereby achieving a seal between the inner wall of the housing 1 and the elastic button 2, and preventing liquid from penetrating into the receiving groove 12 to cause a short circuit between the switch assembly 4 and the circuit board 13.

[0037] The first switch and the second switch can both be existing micro switches. Pressing the two first switches simultaneously can be used to control the vehicle window glass to rise, and pressing the two second switches simultaneously can be used to control the vehicle window glass to fall.

[0038] An escape ring groove 10 is provided at the bottom of the elastic button 2. When the elastic button 2 is pressed, the outer periphery of the escape ring groove 10 is elastically deformed, which saves effort when pressing.

[0039] like Figure 1 As shown, when the elastic button 2 is not pressed, the two first switches and the two second switches are not triggered, and the car door window is in the original state.

[0040] When the car window glass needs to be raised, you can press and hold the right side of the top of the elastic button 2 with your finger. At this time, the pressure on the right side of the elastic button 2 is greater than the pressure on the left side. The right side of the elastic button 2 applies pressure to the two first switches on the right side at the same time, triggering the two first switches at the same time to raise the car window glass. Release your finger and the car window glass stops rising.

[0041] When the car window glass needs to be lowered, you can press and hold the left side of the top of the elastic button 2 with your finger. At this time, the pressure on the left side of the elastic button 2 is greater than the pressure on the right side. The left side of the elastic button 2 applies pressure to the two first switches on the left side at the same time, triggering the two first switches at the same time to lower the car window glass. Release your finger and the car window glass stops lowering.

[0042] When the elastic button 2 is used for too long or is accidentally damaged, the base 3 can be removed, the old elastic button 2 can be taken out, and a new elastic button 2 can be replaced, so as to achieve the reuse of the switch and reduce the maintenance and replacement costs.

[0043] Embodiment 2:

[0044] This embodiment provides a waterproof door and window switch, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0045] A button cap 14 is disposed on the top of the elastic button 2 .

[0046] In this technical solution, the button cap 14 can be made of hard plastic material. The button cap 14 can be pasted on the top of the elastic button 2.

[0047] The button cap 14 can protect the elastic button 2 and prevent the elastic button 2 from being scratched or damaged. In addition, since the button cap 14 has hardness, when the right side or the left side is pressed, the two first switches or the two second switches are subjected to more uniform force.

[0048] Embodiment 3:

[0049] This embodiment provides a waterproof door and window switch, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] The button cap 14 is symmetrically provided with hinge rods 15 on both sides of the Y axis, and the housing 1 is symmetrically provided with hinge grooves on both sides of the Y axis, and the ends of the hinge rods 15 are hinged in the hinge grooves.

[0051] In this technical solution, if Figures 1 to 3 As shown, the hinge rod 15 can be cylindrical, and the hinge groove can be a cylindrical shallow groove, so that the hinge rod 15 is stuck in the hinge groove, so that the button cap 14 is hinged on the top of the housing 1 and rotates. When pressed, the button cap 14 tilts to the left or to the right, which can ensure that the first switch for raising the window glass or the second switch for lowering the window glass is accurately pressed.

[0052] Embodiment 4:

[0053] This embodiment provides a waterproof door and window switch, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] First limit blocks 17 are respectively arranged on both sides of the X-axis in the shell 1, and second limit blocks 18 are respectively arranged on both sides of the X-axis outside the button cap 14. The second limit blocks 18 are located above the first limit blocks 17, and a gap is formed between the second limit blocks 18 and the first limit blocks 17.

[0055] In the present technical solution, the first limiting block 17 can be integrally formed with the housing 1 by using a mold, and the second limiting block 18 can be integrally formed with the button cap 14 by using a mold.

[0056] like Figure 1 As shown, after the button cap is hinged to the top of the housing 1, when the left side of the button cap 14 is pressed, the button cap 14 tilts to the left, and the second limit block 18 on the left side abuts against the first limit block 17. When the left side is pressed, the button cap 14 is limited to avoid excessive pressing to damage the elastic button 2 and the second switch. When the right side of the button cap 14 is pressed, the button cap 14 tilts to the right, and the second limit block 18 on the right side abuts against the first limit block 17. When the right side is pressed, the button cap 14 is limited to avoid excessive pressing to damage the elastic button 2 and the first switch.

[0059] The top surface of the sealing convex ring 11 is a curved surface.

[0060] In the present technical solution, the top surface of the sealing convex ring 11 is a curved surface, which can prevent the bottom of the elastic button 2 from being squeezed by the sealing convex ring 11 for a long time and causing rupture, thereby improving the sealing between the sealing convex ring 11 and the bottom of the elastic button 2, and extending the service life of the elastic button 2.

[0061] Embodiment 6:

[0062] This embodiment provides a waterproof door and window switch, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0063] The top surface of the avoidance ring groove 10 is a curved surface.

[0064] In this technical solution, stress concentration can be avoided to cause the elastic button 2 to crack from the top of the sealing convex ring 11 after long-term use. Therefore, the curved surface of the top of the sealing convex ring 11 can extend the service life of the elastic button 2.

[0065] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
