[0038] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0039] A switch is a commonly used electronic device that can control the on and off of a circuit or allow current to flow to other circuits. A push switch cuts off and closes a circuit by pressing, and is widely used in the field of electronic devices. The push switch includes a panel and a push cover plate. The panel is provided with a mounting groove, and the push cover plate is pressed in the mounting groove to turn the circuit on and off. Because the push cover plate needs to move relative to the inner wall of the mounting groove, a gap is left between the push cover plate and the inner wall of the mounting groove to prevent the inner wall of the groove from hindering the movement of the push cover plate. When the switch was subjected to a water pouring experiment, it was found that water would flow along the gap between the push cover plate and the inner wall of the groove into the live parts inside the switch, causing a short circuit or other circuit failure. In this way, in daily life, when water splashes on the surface of the switch, there is a risk of leakage. Therefore, the waterproof function of the switch is very important.

[0040] In the related art, a method of covering the surface of a push cover with a waterproof film is provided, specifically, a layer of waterproof film is covered on the push cover of the push switch, and the waterproof film can cover the mounting groove, thereby preventing water on the panel surface from flowing into the switch along the mounting groove. However, covering the outer surface of the push cover with a waterproof film will affect the pressing of the switch, thereby affecting the normal use of the switch.

[0041] Combination Figure 1-5 As shown, the embodiment of the present disclosure provides a push switch which is waterproof and does not affect the pressing action of the switch.

[0042] Optionally, combined Figure 1 and Figure 2 As shown, the push switch includes a panel 10, a switch body 20, a push cover plate 30 and a sealing plate 40. The panel 10 is provided with a mounting groove 12; the switch body 20 is arranged in the mounting groove 12; the push cover plate 30 is arranged in the mounting groove 12, and is arranged on the side of the switch body 20 facing the panel 10; the sealing plate 40 is arranged between the push cover plate 30 and the switch body 20, and there is a gap between the push cover plate 30, so as to form a guide groove 41 with the push cover plate 30.

[0043] Optionally, combined Figure 3 As shown, the pressing cover plate 30 includes a cover plate body 31 and a column 32, wherein the cover plate body 31 is perpendicular to the column 32 and connected to the column 32. The sealing plate 40 is connected to the column 32 and has a gap with the cover plate body 31, and a guide groove 41 is formed between the sealing plate 40 and the cover plate body 31.

[0044] Optionally, the sealing plate 40 and the column 32 are integrally formed or non-integrally formed.

[0045] When the sealing plate 40 and the column 32 are not integrally formed, the sealing plate 40 and the column 32 are connected by welding, gluing, etc. Alternatively, the sealing plate 40 and the column 32 are interference fit. This ensures that there is no gap between the sealing plate 40 and the column 32, preventing water on the surface of the panel 10 from flowing into the switch body 20 along the gap between the sealing plate 40 and the pressing cover plate 30.

[0046] Optionally, the cover body 31 is parallel to the panel 10 , the cover body 31 is higher than the plane where the panel 10 is located, or the cover body 31 is flush with the plane where the panel 10 is located.

[0047] Optionally, the sealing plate 40 is parallel or non-parallel to the cover plate body 31. The shape of the sealing plate 40 can be changed according to the structure of the mounting groove 12 and the column 32.

[0048] In the disclosed embodiment, the sealing plate 40 is parallel to the cover plate body 31 .

[0049] When the switch is in use, the cover plate 30 needs to be pressed to switch the power on and off. Since the sealing plate 40 is connected to the column 32, when the cover plate 30 is pressed and moves toward the switch body 20, the sealing plate 40 will be driven to move. The sealing plate 40 is set to be parallel to the cover body 31, and there is a gap between the sealing plate 40 and the cover body 31. When the cover plate 30 is pressed and moves downward, it will not be blocked by the sealing plate 40, and the normal use of the switch will not be affected.

[0050] With the disclosed embodiment, when water flows through the mounting groove 12 on the surface of the panel 10, the water will flow into the guide groove 41 along the gap between the inner wall 121 of the mounting groove 12 and the pressing cover plate 30, thereby preventing the water from flowing along the mounting groove 12 to the switch body 20, thereby achieving the waterproof effect of the press switch.

[0051] In addition, the sealing plate 40 is arranged between the cover body 31 and the switch body 20, and there is a gap between the cover body 31. When the cover 30 is pressed, the sealing plate 40 will not be squeezed, thereby avoiding the sealing plate 40 hindering the pressing of the push switch and ensuring the normal use of the push switch.

[0052] Optionally, the sealing plate 40 surrounds the pressing cover plate 30 , so that the guide groove 41 surrounds the pressing cover plate 30 .

[0053] Optionally, the sealing plate 40 is arranged opposite to the pressing cover plate 30 .

[0054] The guide groove 41 surrounds the pressing cover plate 30 , so that water from all directions can flow into the guide groove 41 , thereby preventing water from flowing into the switch body 20 in all directions.

[0055] Optionally, the sealing plate 40 is interference fit with the inner wall 121 of the installation groove 12. The inner wall 121 of the installation groove 12, the sealing plate 40 and the pressing cover plate 30 together define a guide groove 41.

[0056] When water flows through the mounting groove 12 on the surface of the panel 10, the water will flow into the mounting groove 12 along the groove inner wall 121. The sealing plate 40 is interference fit with the groove inner wall 121, that is, one end of the sealing plate 40 facing the groove inner wall 121 is in close contact with the groove inner wall 121, so that when the water flows along the groove inner wall 121, it is blocked by the sealing plate 40, thereby preventing the water from continuing to flow into the switch body 20 along the groove inner wall 121.

[0057] Optionally, the sealing plate 40 is made of soft sealing material.

[0058] Exemplarily, the sealing plate 40 is a rubber plate or sealing foam.

[0059] During the operation of the push switch, the push cover plate 30 needs to be pressed to move it toward the switch body 20 or away from the switch body 20 to switch the current on and off. The sealing plate 40 is connected to the column 32. When the push cover plate 30 moves toward the switch body 20 or away from the switch body 20, the sealing plate 40 will be driven to move toward the switch body 20 or away from the switch body 20 at the same time. Because the sealing plate 40 and the inner wall 121 of the groove have an interference fit, while the sealing plate 40 fully exerts its waterproof function, the inner wall 121 of the groove has a greater obstruction effect on the sealing plate 40, which is not conducive to the movement of the sealing plate 40, and thus is not conducive to the pressing or resetting of the push cover plate 30.

[0060] The sealing plate 40 is designed to be a soft sealing material to reduce the movement resistance of the groove inner wall 121 to the sealing plate 40, so that the sealing plate 40 can smoothly follow the movement of the pressing cover plate 30 to ensure that the pressing and resetting work of the pressing cover plate 30 is smoothly realized.

[0061] Optionally, combined Figure 4 As shown, the push switch further includes a sealing member 50 , which is disposed between the sealing plate 40 and the inner wall 121 of the mounting groove 12 , so that the sealing plate 40 is interference-fitted with the inner wall 121 of the mounting groove 12 through the sealing member 50 .

[0062] Optionally, the sealing member 50 is made of soft sealing material.

[0063] When the sealing plate 40 is made of a harder material, a sealing member 50 is provided on the side of the sealing plate 40 facing the inner wall 121 of the groove, and the sealing member 50 is made of a soft sealing material, so that the sealing plate 40 can follow the movement of the pressing cover plate 30 relative to the inner wall 121 of the installation groove 12 .

[0064] The sealing plate 40 is made of a relatively hard material to ensure the strength of the sealing plate 40 and prevent the sealing plate 40 from deforming and affecting the sealing function when the number of times the push switch is pressed increases. A sealing member 50 is provided at the edge of the sealing plate 40, and the sealing member 50 is made of a soft sealing material, so that while ensuring the strength of the sealing plate 40, the sealing plate 40 can be moved along the inner wall 121 of the groove to avoid affecting the pressing action of the switch.

[0065] Exemplarily, the sealing member 50 is a rubber plate or sealing foam.

[0066] Optionally, combined Figure 1 As shown, the panel 10 is provided with an opening 11 , and the opening 11 is communicated with the guide groove 41 , so that water in the guide groove 41 flows out of the panel 10 along the opening 11 .

[0067] The panel 10 is provided with an opening 11, which is connected to the guide groove 41, so that water in the guide groove 41 flows out of the panel 10 from the opening 11. This prevents too much water from accumulating in the guide groove 41 to affect the sealing performance of the sealing plate 40 or corrode other components.

[0068] Optionally, the opening 11 is disposed on an inner wall 121 of the mounting groove 12 .

[0069] The opening 11 is provided on the inner wall 121 of the mounting groove 12, communicated with the guide groove 41, and provided corresponding to the guide groove 41, so that water can flow from the guide groove 41 into the opening 11, and flow out of the panel 10 from the opening 11. The inner wall 121 of the groove, the sealing plate 40, and the pressing cover plate 30 define the guide groove 41, and the opening 11 is provided on the inner wall 121 of the groove. When the water in the guide groove 41 flows out from the opening 11, the outflow stroke is reduced, so as to prevent the water from penetrating into the switch body 20 from other gaps.

[0070] Optionally, combined Figure 5 As shown, the inner wall 121 of the mounting groove 12 includes a top wall 1211 and a bottom wall 1212 , and the top wall 1211 and the bottom wall 1212 are arranged opposite to each other; water in the guide groove 41 flows in a direction from the top wall 1211 to the bottom wall 1212 ; wherein the opening 11 is arranged on the bottom wall 1212 .

[0071] The inner wall 121 of the mounting groove 12 further includes a side wall 1213 . The side wall 1213 is disposed between the top wall 1211 and the bottom wall 1212 .

[0072] The pressing cover plate 30, the sealing plate 40 and the inner wall 121 of the groove form a guide groove 41, wherein the side wall 1213, the sealing plate 40 and the pressing cover plate 30 form a side guide groove, the top wall 1211, the sealing plate 40 and the pressing cover plate 30 form a top guide groove, and the bottom wall 1212, the sealing plate 40 and the pressing cover plate 30 form a bottom guide groove.

[0073] like Figure 5 As shown, when the push cover 30 of the push switch is set toward the user, the top guide groove is set at the top and the bottom guide groove is set at the bottom. The opening 11 is set on the bottom wall 1212 and connected to the bottom guide groove. The water in the top guide groove and the side guide groove will be gathered in the bottom guide groove by its own gravity and flow out along the opening 11, so as to drain the water in the guide groove 41.

[0074] Optionally, combined Figure 2 and Figure 4 As shown, the pressing cover plate 30 can move relative to the panel 10 in a direction toward or away from the switch body 20. The switch body 20 includes a base 21, the base 21 is provided with a connecting plate 211, and the base 21 is connected to the panel 10 through the connecting plate 211; there is a travel gap 2111 between the sealing plate 40 and the connecting plate 211, so that when the pressing cover plate 30 moves, the sealing plate 40 is driven to move in the travel gap 2111.

[0075] Optionally, the pressing cover plate 30 is connected to the base 21 .

[0076] Optionally, combined Figure 3 As shown, one of the base 21 and the pressing cover plate 30 is provided with a limiting groove 212, and the other is provided with a limiting protrusion 33, the limiting protrusion 33 is clamped in the limiting groove 212, and can move relative to the limiting groove 212 along the length direction of the limiting groove 212. When the pressing cover plate 30 moves in a direction toward the switch body 20 or away from the switch body 20, the limiting protrusion 33 slides in the limiting groove 212 in the up and down direction.

[0077] The limiting protrusion 33 and the limiting groove 212 are provided to limit the pressing cover plate 30 to prevent the pressing cover plate 30 from being disconnected from the base 21 when rebounding.

[0078] There is a gap between the sealing plate 40 and the connecting plate 211, which is a travel gap 2111. By reserving the travel gap 2111, when the pressing cover plate 30 is pressed in the direction of the switch body 20, the pressing cover plate 30 drives the sealing plate 40 to move in the direction of the switch body 20. Since there is a travel gap 2111 between the sealing plate 40 and the connecting plate 211, the sealing plate 40 can move in the direction of the connecting plate 211, thereby preventing the pressing cover plate 30 from being unable to be pressed due to the connecting plate 211 blocking the movement of the sealing plate 40, thereby affecting the normal use of the switch.

[0079] Optionally, combined Figure 4As shown, the switch body 20 also includes a button core 22, which is connected to the pressing cover plate 30 and is provided with a first contact 221; the base 21 is provided with a second contact 222, and when the pressing cover plate 30 moves toward or away from the switch body 20, it drives the button core 22 to move, so that the first contact 221 and the second contact 222 are in contact or out of contact; wherein, the distance between the first contact 221 and the second contact 222 is smaller than the travel gap 2111.

[0080] The button core 22 is provided with a first contact 221, and a second contact 222 is provided on the side of the bottom of the base 21 facing the button core 22. When the first contact 221 and the second contact 222 are in contact, the switch can be powered on, and when the first contact 221 and the second contact 222 are out of contact, the switch can be powered off. The button core 22 is connected to the pressing cover plate 30. When the pressing cover plate 30 moves toward the switch body 20, the button core 22 is driven to move toward the base 21, so that the first contact 221 and the second contact 222 are in contact. When the pressing cover plate 30 rebounds, the first contact 221 and the second contact 222 are out of contact.

[0081] Optionally, the push switch also includes a first elastic member 60, which corresponds to the first contact 221. When the pressing cover 30 is pressed downward, the first elastic member 60 is compressed to generate an elastic force, and the first contact 221 is brought into contact with the second contact 222 through the elastic force.

[0082] Optionally, the first elastic member 60 is a spring.

[0083] The distance between the first contact 221 and the second contact 222 is the contact gap 2221. The travel gap 2111 is larger than the contact gap 2221, so that when the cover plate 30 is pressed downward, the first contact 221 and the second contact 222 can be fully contacted, preventing the first contact 221 and the second contact 222 from failing to contact due to the travel gap 2111 being too small.

[0084] Optionally, the travel gap 2111 is greater than the travel of the first elastic member 60 .

[0085] The first elastic member 60 is compressed to generate elastic force, under the action of which the first contact 221 and the second contact 222 are in close contact. When the travel gap 2111 is greater than the travel of the first elastic member 60, the first elastic member 60 can be fully compressed to generate sufficient elastic force to make the first contact 221 and the second contact 222 contact.

[0086] Optionally, the push switch further includes a second elastic member 70 , and the second elastic member 70 is disposed between the button core 22 and the base 21 .

[0087] When the pressing cover plate 30 is pressed to move toward the bottom of the base 21, the pressing cover plate 30 drives the button core 22 to move toward the base 21, thereby squeezing the second elastic member 70, causing the second elastic member 70 to generate elastic force, so that the pressing cover plate 30 rebounds through the elastic force of the second elastic member 70.

[0088] Optionally, combined Figure 4 As shown, the push switch further includes a lock hook 80 , which is disposed at the bottom of the base 21 and corresponds to the second elastic member 70 .

[0089] When the pressing cover plate 30 is pressed to move toward the bottom of the base 21, the pressing cover plate 30 drives the button core 22 to move toward the bottom of the base 21, thereby squeezing the second elastic member 70 and the first elastic member 60, and locking the second elastic member 70 with the locking hook 80, so that the second elastic member 70 remains in a compressed state, thereby keeping the first elastic member 60 in a compressed state, and keeping the first contact 221 and the second contact 222 in contact. The pressing cover plate 30 is pressed again to continue to move toward the bottom of the base 21, and the locking hook 80 releases the second elastic member 70, so that the second elastic member 70 rebounds, thereby driving the first elastic member 60 to rebound, and the first contact 221 and the second contact 222 are out of contact, and the pressing cover plate 30 is reset.

[0090] The push switch provided in the embodiments of the present disclosure can achieve the following technical effects:

[0091] The pressing cover plate 30, the switch body 20 and the sealing plate 40 are all arranged in the installation groove 12. The pressing cover plate 30 is arranged on the side of the switch body 20 facing the panel 10. The sealing plate 40 is arranged between the pressing cover plate 30 and the switch body 20, and there is a gap between the pressing cover plate 30 and the pressing cover plate 30, so as to form a guide groove 41 with the pressing cover plate 30. When water flows through the installation groove 12 on the surface of the panel 10, the water will flow into the guide groove 41 along the gap between the inner wall 121 of the installation groove 12 and the pressing cover plate 30, so as to avoid water flowing into the switch body 20. There are gaps between the sealing plate 40, the pressing cover plate 30 and the switch body 20, so that during the switch pressing process, the pressing action of the pressing cover plate 30 is not affected by the setting of the sealing plate 40, thereby avoiding affecting the use of the switch.
