Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The present application embodiment discloses a highly waterproof push button switch with a night vision mark. Figure 1 and Figure 2, Highly waterproof push button switch with night vision marking includes:

[0046] A housing 1, a circuit board 2 placed in the housing 1, a button 3 and a rubber sleeve 4. A switch is provided at a position on the circuit board 2 corresponding to the button 3. In the specific setting, the switch can be a micro switch. Considering the frequency of use, the switch can further be a high-durability micro switch.

[0047] The housing 1 is provided with:

[0048] The waterproof cover 5 is located on a side of the circuit board 2 close to the button 3 and is configured to wrap the circuit board 2;

[0050] Thus, on the one hand, since the button 3 is provided with a fluorescent mark 31, the situation that the button 3 cannot be accurately found at night or in a weak light environment can be effectively improved, thereby improving the convenience of the present application when in use. On the other hand, since a waterproof cover 5 is also provided for wrapping the circuit board 2, even if the rubber cover 4 is damaged, the waterproof cover 5 can still effectively waterproof the circuit board 2 and the electronic components thereon, thereby greatly improving the waterproof performance of the present application.

[0051] In order to ensure the high waterproof performance of the waterproof cover 5, refer to Figure 2 , Figure 3 and Figure 4 , the housing 1 is also provided with:

[0052] The sink 11 is arranged on the side of the housing 1 away from the button 3, and the waterproof cover 5 and the circuit board 2 are inserted and adapted to the sink 11;

[0053] The base 9 is disposed on a side of the circuit board 2 facing away from the waterproof cover 5 , and is configured to press the circuit board 2 and the waterproof cover 5 onto the sink 11 .

[0054] In some embodiments, the base 9 is threadedly connected to the housing 1 , and the circuit board 2 and the waterproof cover 5 can be pressed onto the sink 11 by rotating the base 9 .

[0055] In some embodiments, the base 9 is snap-connected to the outer shell 1. When the base 9 is snap-fitted to the outer shell 1, the circuit board 2 and the waterproof cover 5 are pressed onto the sink 11. For example, a plurality of slots 14 are provided on the inner wall of the outer shell 1. The base 9 has a plurality of card blocks 91 corresponding to the plurality of card slots 14. The card block 91 has a guiding slope on a side close to the circuit board 2. By pushing the base 9 so that the card block 91 is embedded in the card slot 14, the circuit board 2 and the waterproof cover 5 can be pressed while the base 9 is fixed.

[0056] In addition, the waterproof cover 5 comprises:

[0057] The skirt 51 is arranged in close contact with the circuit board 2, and a sealing ring 53 is arranged on the side of the skirt 51 facing away from the circuit board 2;

Specifically, the cover portion 52 and the skirt 51 are integrally formed, and the cover portion 52 covers the outer periphery of the switch on the circuit board 2 .

[0059] In this way, the circuit board 2 and the waterproof cover 5 are pressed against the sink 11 by means of the base 9, and the sealing ring 53 is squeezed, thereby improving the tightness of the fit between the waterproof cover 5 and the circuit board 2, and can significantly improve the sealing and waterproof performance between the housing 1 and the circuit board 2; and the setting of the cover part 52 can make the waterproof cover 5 adapt to the shape of the switch on the circuit board 2, thereby facilitating the triggering of the switch on the circuit board 2.

[0060] In addition, refer to Figure 1 and Figure 2 The aforementioned fluorescent mark 31 may cover the entire width or part of the button 3, or may be provided with a button 3 mark on the side of the button 3 away from the circuit board 2, and the fluorescent mark 31 is located in the button 3 mark. When setting it specifically, it can be flexibly designed according to actual needs. In this embodiment, the fluorescent mark 31 is selected to be set in the button 3 mark to clearly display the button 3 function pattern.

[0061] In order to facilitate the assembly of the button 3 and the rubber sleeve 4, refer to Figure 2 and Figure 3 , this application also provides:

[0062] The button seat 6 and the button 3 are mounted on the button seat 6, and the rubber sleeve 4 seals and connects the button seat 6 and the housing 1. Specifically, the rubber sleeve 4 is formed by connecting two rubber sleeves of different diameters in one piece, and there is a folding portion between the two rubber sleeves for connecting the two in one piece, the large-diameter rubber sleeve is connected to the housing 1, and the small-diameter rubber sleeve is connected to the button seat 6; thus, when the button seat 6 moves in the housing 1, the rubber sleeve 4 can not only seal and waterproof the button seat 6 and the housing 1, but also the folding portion on the rubber sleeve 4 can adapt to the frequent movement of the button seat 6. In order to reduce the probability of damage to the folding portion on the rubber sleeve 4, the folding portion can be shielded after the button 3 is assembled on the button seat 6.

[0063] The slider 7 is slidably disposed in the housing 1, and the button seat 6 is buckled and mounted on the slider 7. The side of the slider 7 close to the circuit board 2 has a docking portion corresponding to the switch on the circuit board 2;

[0064] When the button 3 is pressed, the button seat 6 pushes the slider 7 to press the switch on the circuit board 2 .

[0065] And, refer to Figure 3 and Figure 4 A plurality of ribs 71 arranged along the sliding direction are fixedly connected to the outer peripheral wall of the slider 7, and a plurality of rib grooves 13 slidingly matched with the ribs 71 are opened on the inner wall of the housing 1. The plurality of ribs 71 and the plurality of rib grooves 13 are arranged in a one-to-one correspondence.

[0066] And in another embodiment, referring to Figure 4 The rib groove 13 is closed at one end close to the button seat 6 to limit the upward travel of the slider 7, so that after the button seat 6 is assembled to the slider 7 and the button 3 is assembled to the button seat 6, the three can be prevented from falling out of the housing 1.

[0067] In this way, the slider 7 slides with the help of the ribs 71 thereon and the rib grooves 13 on the housing 1, which can control the movement direction of the button 3 and the button seat 6, and also provide a smooth feel for the button seat 6 and the button 3 when being pressed.

[0068] In addition, as some accessories, refer to Figure 1 , this application also provides:

[0069] The wire harness component 8 includes electric wires 81 connected to the circuit board 2 , and terminals and connectors 82 connected to the electric wires 81 .

[0070] The implementation principle of a highly waterproof push button switch with night vision marking in the embodiment of the present application is as follows:
