Description

Technical Field

[0001] This application relates to the technical field of lighting equipment, and particularly to a push switch structure and a vehicle lamp. Background Art

[0002] In existing portable lamps, a switch structure is usually used to control the turning on or off of the light. The form of the switch structure can be a toggle type or a push type. Currently, a push switch is usually used for switch control. The light is turned on by pressing the switch structure, or the light mode is adjusted by pressing the switch structure multiple times.

[0003] The existing push switch structure usually uses a button micro switch for power-on control. A plastic push cap is connected to the housing, and the button micro switch is pressed by the push cap to realize the light switch function. However, when directly using the push cap to press the button micro switch, during the pressing process, only the extrusion of the button micro switch causes the push cap to return to its original position after being pressed, resulting in very small deformation amplitudes for both the pressing and returning of the push cap. The user's pressing feeling feedback is not obvious, leading to the problem of inconvenient use for the user.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Utility Model

[0005] In view of the above deficiencies of the existing technology, the purpose of this application is to provide a push switch structure, which solves the problem in the existing technology that the deformation amplitudes of both the pressing and returning of the push cap are very small, the user's pressing feeling feedback is not obvious, and the user's use is inconvenient.

[0014] Optionally, the bending part further includes: a U-shaped plate, one end of the U-shaped plate is connected to the arc-shaped plate, and the other end is fixed to the inner side of the bottom shell;

[0015] The opening side of the U-shaped plate faces away from the key switch.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] To make the purpose, technical solutions and advantages of the present application clearer and more definite, the following further elaborates on the present application with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] Embodiment 1

[0036] As Figure 1, Figure 2 As shown, this embodiment provides a push switch structure for being disposed on the bottom case 100. Specifically, the push switch structure can be disposed at the rear end of the bottom case 100. Pressing the push switch structure forward can achieve circuit connection and disconnection. A key hole 110 is formed in the bottom case 100. The bottom case 100 is divided into an inner side and an outer side. The inner side is inside the lamp body. A key switch 120 is fixedly disposed on the inner side of the bottom case 100. The key switch 120 faces the key hole 110. The key switch 120 adopts a side-press tactile micro switch. When the key hole 110 is formed on the side of the bottom case 100, the key position of the side-press tactile micro switch is located at the position of the key hole 110. By pressing the key switch 120, the lighting and turning off of the vehicle lamp can be controlled.

[0037] As Figure 1 , Figure 2 , Figure 3 As shown, the push switch structure of this embodiment mainly includes: a waterproof button part 200 and a resilient plate part 300. The waterproof button part 200 is inserted into the key hole 110 and seals the key hole 110. In a specific structure, the waterproof button part 200 has a certain elasticity and can be installed in the key hole 110. The waterproof button part 200 is deformed by the extrusion of the key hole 110 and fills the key hole 110, which can achieve the plugging of the key hole 110 and has a certain waterproof function. The resilient plate part 300 is located between the waterproof button part 200 and the key switch 120, and the resilient plate part 300 has a certain elasticity. Specifically, the resilient plate part 300 is located on the front side of the waterproof button part 200, and the key switch 120 is located on the front side of the movable end 310 of the resilient plate part 300. When a user presses the waterproof button part 200 forward, the waterproof button part 200 is deformed forward and extrudes the movable end 310 of the resilient plate part 300, so that the movable end 310 of the resilient plate part 300 generates elastic deformation through the extrusion of the waterproof button part 200 and touches the key switch 120, thereby realizing the on / off control of the lamp.

[0038] A push-button switch structure in this embodiment, by arranging a waterproof button part 200 in the button hole 110 of the bottom shell 100, while sealing the button hole 110, can be deformed inward under the external pressing force. One end of the inner return spring plate 300 is fixed and the other end is movable. The waterproof button part 200 deformed inward by the force abuts against and squeezes the return spring plate 300, so that the movable end 310 of the return spring plate 300 is squeezed to produce elastic deformation and moves inward, thus abutting against and squeezing the button switch 120 located inside the bottom shell 100. The button switch 120 is triggered to generate a control signal to realize the control of the vehicle lamp. When the lamp is turned on and the user no longer applies force to the waterproof button part 200, under the action of the return force of the return spring plate 300, the movable end 310 returns to its original position and pushes the waterproof button part 200 back to its original position. In this process, with the auxiliary action of the elastic deformation of the return spring plate 300, the pressing and returning amplitudes are large, increasing the user's pressing feel and making the user's feedback on the pressing process more obvious, optimizing the structure of the push-button switch and facilitating the user's use.

[0039] As Figure 1 , Figure 2 , Figure 3 shown, further, the return spring plate 300 in this embodiment specifically includes: a bending part 320. One end of the bending part 320 is fixedly located inside the bottom shell 100. A fixing bracket 130 is fixed inside the bottom shell 100. The fixing bracket 130 is used to fix the light-emitting device, so that the front end of the bending part 320 is fixedly connected to the fixing bracket 130, and the bending part 320 can be stably fixed inside the bottom shell 100. The rear end of the bending part 320 is connected to the movable end 310, so that the movable end 310 is suspended between the waterproof button part 200 and the button switch 120. When the waterproof button part 200 presses the movable end 310 forward, the suspended movable end 310 is pressed to cause the bending part 320 to produce elastic deformation, so that the movable end 310 can move forward with a certain return force, enabling the user to more obviously feel the pressing feeling of the button, thus optimizing the structure of the push-button switch.

[0040] As Figure 1 , Figure 2 , Figure 3As shown in the figure, further, the bending part 320 in this embodiment specifically includes: an arc-shaped plate 321. The lower end of the arc-shaped plate 321 is connected to the movable end 310, and the other end of the arc-shaped plate 321 bends in a direction away from the waterproof button part 200. For example, the arc-shaped plate 321 is located above the movable end 310. After the arc-shaped plate 321 extends upward, it bends forward to form an arc-shaped structure. The movable end 310 specifically includes a pressure-bearing flat plate 311, and the pressure-bearing flat plate 311 is connected to the lower end of the arc-shaped plate 321. The width of the pressure-bearing flat plate 311 is greater than the width of the arc-shaped plate 321. When the pressure-bearing flat plate 311 is squeezed by the waterproof button part 200, it has a larger force-bearing surface, and when pressing the key switch 120 forward, the force is dispersed and better contacts the key switch 120. After the pressure-bearing flat plate 311 is squeezed by the waterproof button part 200, due to the arc-shaped structure of the arc-shaped plate 321, the arc-shaped plate 321 is more likely to produce elastic deformation. The arc-shaped plate 321 has a smaller width, which also makes the arc-shaped plate 321 more sensitive to deformation after being stressed. Thus, the arc-shaped plate 321 provides a stable elastic force to the pressure-bearing flat plate 311, playing a role in improving the pressing feeling of the key.

[0041] As Figure 1 , Figure 2 , Figure 3 As shown in the figure, further, the bending part 320 in this embodiment further includes: a U-shaped plate 322. One end of the U-shaped plate 322 is connected to the arc-shaped plate 321, and the other end is fixed to the inner side of the bottom shell 100. The opening side of the U-shaped plate 322 faces away from the key switch 120. In the specific structure, the front end of the U-shaped plate 322 is fixedly connected to the fixing bracket 130 and is spaced a certain distance from the fixing bracket 130, which is beneficial to increasing the elasticity of the U-shaped plate 322. The rear end of the U-shaped plate 322 is fixedly connected to the upper end of the arc-shaped plate 321, so that the entire U-shaped plate 322 is located above the key switch 120, facilitating the space above the key switch 120, enabling the U-shaped plate 322 to have a larger opening side, and the longer length of the U-shaped plate 322 is beneficial to the U-shaped plate 322 to produce elastic deformation.

[0042] The fixing bracket 130, the U-shaped plate 322, the arc-shaped plate 321, and the pressure-bearing flat plate 311 in this embodiment are integrally formed. The integrally formed structure enables the entire rebounding plate member 300 to be more stably fixed to the fixing bracket 130, so that the rebounding plate member 300 is more stably arranged inside the bottom shell 100.

[0043] As Figure 1 , Figure 2 , Figure 3As shown, further, the waterproof button part 200 in this embodiment specifically includes: a flexible cap part 210 and a rigid part 220. The flexible cap part 210 is inserted into the key hole 110. The flexible cap part 210 can be made of a silicone cap. Since the flexible cap part 210 made of silicone is relatively soft, when the flexible cap part 210 is squeezed by the user, it is easy to deform and be pressed. And when the flexible cap part 210 made of silicone is installed in the key hole 110, it can also seal the key hole 110 and play a certain waterproof role. The rigid part 220 is embedded in the flexible cap part 210 and protrudes from the end face of the flexible cap part 210 facing the key switch 120. When the flexible cap part 210 is squeezed by the user, the rigid part 220 moves forward, and the relatively hard rigid part 220 squeezes the rebound plate 300. The rigid part 220 is used for force transmission, making it easier for the rebound plate 300 to be deformed by force, thereby further enhancing the key feel and facilitating the user to use. In addition, during the installation process, the relatively soft flexible cap part 210 is first compressed and shrunk and squeezed into the key hole 110 to realize the installation of the flexible cap part 210, and then the rigid part 220 is inserted into the flexible cap part 210, so that the middle of the waterproof button part 200 has a greater hardness and the flexible cap part 210 on the outside is not easy to shrink greatly, so that the waterproof button part 200 is stably installed in the key hole 110 and is not easy to come out.

[0044] As Figure 1 , Figure 2 , Figure 3 As shown, further, the flexible cap part 210 in this embodiment specifically includes: an outer sealing platform 211, a connecting platform 214, and an inner anti-withdrawal platform 215. The outer diameter of the outer sealing platform 211 is larger than the outer diameter of the connecting platform 214, the outer diameter of the inner anti-withdrawal platform 215 is larger than the outer diameter of the connecting platform 214, and the outer sealing platform 211, the connecting platform 214, and the inner anti-withdrawal platform 215 are integrally formed. After the flexible cap part 210 is installed in the key hole 110, the outer sealing platform 211 is arranged in the sink 111 outside the key hole 110, the connecting platform 214 is connected to the outer sealing platform 211 and is inserted into the key hole 110, and the inner anti-withdrawal platform 215 is connected to the connecting platform 214 and is located inside the bottom shell 100 to abut against the inner wall of the bottom shell 100. The outer sealing platform 211 and the inner anti-withdrawal platform 215 with larger outer diameters are used to limit the inner and outer sides of the bottom shell 100 respectively. After the outer sealing platform 211 is matched and limited in the sink 111, the flexible cap part 210 is stably fixed on the bottom shell 100.

[0045] As Figure 1 , Figure 2 , Figure 3As shown, further, a key sealing protrusion 212 is provided on the outer wall of the outer plugging platform 211 in this embodiment. The key sealing protrusion 212 is embedded in the sink 111 by extrusion. The key sealing protrusion 212 can be a semi-circular structure and is integrally formed with the outer plugging platform 211. The key sealing protrusion 212 is equivalent to a sealing ring. After the outer plugging platform 211 is clamped in the sink 111, since the key sealing protrusion 212 protrudes from the outer circular surface of the outer plugging platform 211, the key sealing protrusion 212 is more tightly pressed against the inner wall of the sink 111, basically preventing water from entering and improving the waterproof level.

[0046] As Figure 1 , Figure 2 , Figure 3 As shown, further, a first material-reducing groove 213 is formed on the end surface of the outer plugging platform 211 in this embodiment facing the inner anti-retreat platform 215. The first material-reducing groove 213 surrounds the connecting platform 214. The first material-reducing groove 213 is located on the front end surface of the outer plugging platform 211, so that the radial thickness at this position becomes smaller. Then, the front end of the outer plugging platform 211 is easily deformed. When the outer plugging platform 211 is clamped into the sink, the front end is deformed and is more easily squeezed into the sink, making the assembly process easier.

[0047] A second material-reducing groove 216 is formed on the end surface of the inner anti-retreat platform 215 in this embodiment facing the outer plugging platform 211. The second material-reducing groove 216 surrounds the connecting platform 214. The second material-reducing groove 216 is located on the rear end surface of the inner anti-retreat platform 215, so that the radial thickness of the inner anti-retreat platform 215 becomes smaller. Then, the front end of the inner anti-retreat platform 215 is easily deformed. During the installation process of the inner anti-retreat platform 215, the inner anti-retreat platform 215 is more easily deformed and shrunk. The shrunk inner anti-retreat platform 215 is more easily passed through the key hole 110 and rebounds and expands after completely entering the inside of the bottom case 100, so that the assembly process of the inner anti-retreat platform 215 is easier.

[0048] As Figure 1 , Figure 2 , Figure 3 As shown, further, the rigid part 220 in this embodiment specifically includes: a plugging rod 221, a connecting disk 222, and a top platform 223. The plugging rod 221 is embedded in the flexible cap part 210. The plugging rod 221 has a certain length in the front-rear direction, which is convenient for inserting into the flexible cap part 210 and plays a role of not being easily detached. In addition, it can also enhance the hardness at the center of the flexible cap part 210, so that the installed flexible cap part 210 is not easily deformed and detached. The connecting disk 222 is connected to the plugging rod 221 and is connected to the inner end surface of the flexible cap part 210. The top platform 223 is connected to the connecting disk 222, and the top platform 223 protrudes toward the movable end 310 of the rebounding plate member 300. The plugging rod 221, the connecting disk 222, and the top platform 223 are integrally formed, making the structure more stable.
