[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0033] Referring to Figure 1 and Figure 2 , an embodiment of the present application discloses a high waterproof door opening switch assembly with a status indicator for automobiles, which includes an outer shell 11 for mounting on the outside door handle of the vehicle. The outer shell 11 is in a hollow cylindrical shape, and the following are sequentially arranged in the outer shell 11 from the bottom to the top:

[0034] A base 12, mounted at the bottom of the outer shell 11;

[0035] A circuit board 2, mounted on the base 12, on which a light-emitting component 21 and a microswitch 22 are provided. The light-emitting component 21 can be an LED lamp; specifically, a groove 122 is opened at the bottom of the base 12, and the circuit board 2 is mounted in the groove 122; through holes 123 for components such as the light-emitting component 21 and the microswitch 22 to pass through are opened on the bottom wall of the groove 122;

[0036] The button 3 is provided at the top of the housing 11 and is used to trigger the micro switch 22, and it has a light-transmitting lighting area 31 thereon;

[0037] The soft rubber sleeve 4 is provided at the gap between the button 3 and the housing 11, and its outer ring side is fixedly connected to the housing 11 and its inner ring side is fixedly connected to the button 3; and

[0038] The connecting component is provided between the button 3 and the base 12 and is used to achieve a stable pressing effect of the button 3.

[0039] After such a setting, by providing the lighting area 31 on the button 3 and providing the light-emitting element 21 on the circuit board 2, it is possible to automatically light up the light-emitting element 21 after the vehicle is powered on. That is, after the vehicle is unlocked, the lighting area 31 of the button 3 on the door handle is lit, which can enable the user to quickly find the position of the door handle and greatly improve the convenience during use. Moreover, since the soft rubber sleeve 4 is provided between the button 3 and the housing 11, the waterproof effect of the switch assembly of the present application is greatly improved, so that even when the switch assembly of the present application is installed outside the vehicle door, a long and effective service life can be ensured.

[0040] Specifically, referring to Figure 2 and Figure 3 , a light guide column 5 is provided between the circuit board 2 and the button 3. One end of the light guide column 5 is aligned with the lighting area and the other end is aligned with the light-emitting element 21, and the outer diameter of the light guide column 5 near the button 3 end is larger than the outer diameter of its other end. Specifically, the upper part of the light guide column 5 is in the shape of an isosceles trapezoid and the lower part is in the shape of a rectangle. The lower base of its isosceles trapezoid corresponds to the long strip-shaped lighting area and the rectangular head end corresponds to the light-emitting element 21.

[0041] The connecting component includes:

[0042] The slider 6 is slidably arranged on the inner wall of the housing 11. The slider 6 has a light-transmitting hole 61 through which the smaller-diameter end of the light guide column 5 passes, and the hole wall of the light-transmitting hole 61 is slidably adapted to the rectangular part of the light guide column 5;

[0043] The column 62 is fixedly connected to the side of the slider 6 close to the circuit board 2, and the column 62 is arranged corresponding to the micro switch 22;

[0044] A guiding structure is provided between the slider 6 and the inner wall of the housing 11.

[0045] Among them, the guiding structure includes a plurality of guiding ribs 111 fixedly connected to the inner wall of the housing 11 and a plurality of guiding grooves 63 provided on the outer peripheral side wall of the slider 6. The plurality of guiding ribs 111 are slidably adapted to the plurality of guiding ribs 111 one by one, and the guiding ribs 111 are arranged along the arrangement direction of the button 3 and the circuit board 2. In this embodiment, four guiding ribs 111 are spaced apart on the inner wall of the housing 11.

[0046] After such a setting, when the button 3 is pressed, the button 3 moves downward and pushes the light guide column 5 to move in the direction close to the circuit board 2. Since the light guide column 5 is clamped in the light-transmitting hole 61 on the slider 6 at this time, the slider 6 can move downward together with the button 3. Through the sliding fit of the plurality of guiding ribs 111 around the slider 6 and the guiding groove 63 on the housing 11, the sliding movement of the button 3 after being pressed is smoother and more stable. At the same time, the pressing feedback is obvious and the feel is better. Moreover, the setting of the light guide column 5 can not only drive the slider 6 to move together, but also improve the uniformity of the light emitted by the light-emitting component 21, so that the illumination brightness of the lighting area on the button 3 is good in consistency.

[0047] Furthermore, if a reflective paint is coated on the outer wall of the light guide column 5, it can further brighten the lighting area on the button 3 and further improve the night visibility.

[0048] And in order to further improve the waterproof performance of the switch assembly of the present application, referring to Figure 2 and Figure 3 , there is a waterproof soft rubber cover 121 on the base 12 that completely covers the circuit board 2. The waterproof soft rubber cover 121 is transparent, that is, it does not affect the emission of the light from the light-emitting component 21, and can provide relatively comprehensive waterproof protection for the components on the surface of the circuit board 2; and a potting layer is provided on the side of the base 12 facing away from the circuit board 2. The potting layer can completely encapsulate the circuit board 2 in the groove 122 to avoid the possibility of rainwater or water vapor leaking onto the circuit board 2.

[0049] In addition, a water-blocking edge 64 is fixedly connected to the side of the slider 6 facing away from the circuit board 2. The button 3 is sleeved outside the water-blocking edge 64. The fixed connection part of the soft rubber sleeve 4 and the button 3 is located between the outer edge of the button 3 sleeve and the water-blocking edge 64; an installation groove 112 is provided on the housing 11 and is arranged around its contour. A convex edge 41 that is snap-fitted with the installation groove 112 is integrally formed on the soft rubber sleeve 4.

[0050] In this way, the waterproof effect of the soft rubber sleeve 4 on the gap between the button 3 and the housing 11 can be significantly improved, and the convenience of assembling the soft rubber sleeve 4 can be ensured.

[0051] The implementation principle of the door opening switch assembly with a high waterproof performance and a status indicator for an automobile in the embodiment of the present application is as follows:

[0052] By setting a lighting area 31 on the button 3 and a light-emitting component 21 on the circuit board 2, it can be realized that the light-emitting component 21 is automatically lit after the vehicle is powered on, that is, after the vehicle is unlocked, the lighting area 31 of the button 3 on the door handle is lit, which can enable the user to quickly find the position of the door handle and can greatly improve the convenience during use. Moreover, since a soft rubber sleeve 4 is provided between the button 3 and the housing 11, the waterproof effect of the switch assembly of the present application is greatly improved, so that even when the switch assembly of the present application is installed outside the vehicle door, a long and effective service life can be ensured.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
