[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] One embodiment of this utility model, such as Figure 1-9 As shown, a switch button structure includes: Button 1, the top surface of button 1 is provided with light-transmitting area 11 and light-transmitting area 12; A light shield 2 is located at the lower end of button 1. The light shield 2 has a light guide groove 1 21 and a light guide groove 22. A light guide 5 is located in the light guide groove 22. Silicone button 3 is positioned between light shield 2 and PCB assembly 4; PCB assembly 4 is located below light shield 2. PCB assembly 4 is provided with indicator light 1 41 and indicator light 2 42. The light-transmitting area 11 of indicator light 1 41 is located at both ends of light guide groove 21. Indicator light 2 42 and the light-transmitting area 12 are located at both ends of light guide groove 22. The lower end of button 1 is provided with an extension plate 141 extending into the light shield 2, and the extension plate 141 is engaged with the inner cavity of the light shield 2.

[0020] In this embodiment, indicator light 41 and indicator light 42 are the backlight and function light, respectively. Light-transmitting area 11 and light-transmitting area 2 are the backlight light transmission area and function light transmission area, respectively. However, this is not a limitation, and the switching of both types of indicator lights is applicable.

[0021] The button is integrally formed through a two-stage injection molding process. Specifically, button 1 includes an outer upper shell 13 and an inner upper shell 14. The outer upper shell 13 covers the outside of the inner upper shell 14. Light-transmitting area one 11 and light-transmitting area two 12 are connected to the inner upper shell 14 and integrally formed with the main body of the inner upper shell 14 through a single injection molding process. The outer upper shell 13 is integrally formed with the inner upper shell 14 through a two-stage injection molding process. The upper ends of light-transmitting area one 11 and light-transmitting area two 12 protrude from the inner upper shell 14 and are embedded in the outer upper shell 13.

[0022] In the above structure, the first light-transmitting area 11 and the second light-transmitting area 12 are connected to the inner upper shell 14, and the first light-transmitting area 11, the second light-transmitting area 12 and the inner upper shell 14 are integrally formed by one injection molding. The first light-transmitting area 11, the second light-transmitting area 12 and the inner upper shell 14 are made of light-colored light-transmitting material. In this embodiment, in some embodiments, the first light-transmitting area 11, the second light-transmitting area 12 and the inner upper shell 14 are made of the same gray light-transmitting material. When both indicator lights 1 41 and 2 42 are not lit, the first light-transmitting area 11 and the second light-transmitting area 2 12 have the same color. When both indicator lights 1 41 and 2 42 are lit, they present different brightness effects due to the large difference in brightness.

[0023] The outer upper shell 13 is made of dark-colored light-blocking plastic material. In some embodiments, the outer upper shell 13 is made of black light-blocking material. The outer upper shell 13 is integrally formed with the inner upper shell 14 through secondary injection molding. Light-transmitting area one 11 and light-transmitting area two 12 protrude from the inner upper shell 14 and are embedded in the outer upper shell 13. Light-transmitting area one 11 and light-transmitting area two 12 are integrally formed from the same material, and the outer upper shell 13 and inner upper shell 14 of the button 1 are integrally formed through secondary injection molding, which simplifies the mold structure and button molding process, reduces the unit cost by 15%, saves costs, and improves production efficiency and production quality.

[0024] like Figure 3 , 7 As shown, the light-shielding body 2 is also made of dark-colored light-blocking material and is fixedly connected to the button 1. An extension plate 141 is located at the bottom of the inner upper shell 14, and a slot 142 is provided on the extension plate 141. Inside the light-shielding body 2, a buckle 23 is provided corresponding to the slot 142, and the buckle 23 engages with the slot 142. In this embodiment, the buckle 23 is a boss structure with a beveled surface. This engagement structure ensures a stable connection between the button 1 and the light-shielding body 2, resulting in good motion linkage when pressed, thereby improving the overall stability and waterproof performance of the switch.

[0025] In one embodiment of this utility model, a light guide body 5 is provided in the second light guide groove 22, while no light guide component is provided in the first light guide groove 21. Furthermore, there is light isolation between the first light guide groove 21 and the second light guide groove 22, thereby achieving a high brightness difference effect between the first indicator light 41 and the second indicator light 42, and ensuring that the lights of the two do not interfere with each other. Additionally, the first light-transmitting area 11 and the second light-transmitting area 12 are made of the same material and integrally molded. The outer upper shell 13 and inner upper shell 14 of the button 1 are integrally molded using 2K (secondary) injection molding, simplifying the mold structure and button molding process, reducing the unit cost by 15%, saving costs, and improving production efficiency and quality. In one embodiment of this utility model, as... Figure 1 , 3 As shown in Figure 8, the two ends of the light guide are respectively positioned opposite to indicator light 42 and light-transmitting area 22. The light guide 5 is fixedly connected to the light shield 2. Specifically, the light guide 5 has multiple positioning protrusions 51 on its exterior. The positioning protrusions 51 abut against the inner wall of the light guide groove 22. The positioning protrusions 51 have guide slopes. The lower end of the light guide 5 also has a positioning protrusion 52. The lower end of the light guide groove 22 has a positioning step 27. The middle of the positioning protrusion 52 has a guide groove that matches the positioning step 27, and the top of the positioning protrusion 52 abuts against one side of the positioning step 52. When installing the light guide 5, the light guide 5 is inserted into the light guide groove 22. The positioning protrusions 51 and 52 limit the position of the light guide 5 in the light guide groove 22. Then, the light guide 5 is fixedly connected to the light shield 2 by means of bonding or other methods.

[0026] The top of the outer shell 13 is arc-shaped for easy pressing. A micro switch is provided on the PCB assembly. The silicone button 3 is located between the light shield 2 and the PCB assembly. When the button 1 pushes the light shield 2 down a certain distance, it will trigger the micro switch. The triggering of the micro switch controls the on / off state of the circuit on the PCB assembly. When force is applied to the button 1, the button 1, the light shield 2, and the light guide 5 move downward together, triggering the micro switch and turning on the second indicator light 42, which is the function light, illuminating the second light-transmitting area 12. The light shield 31 of the silicone button 3 can provide a rebound force to drive the upward movement. After the external force disappears, it pushes the light guide 5, the light shield 2, and the button 1 to reset. Pressing the button again can turn off the second indicator light 42. The first indicator light 41 is the backlight, which is in a constant-on mode after the car is powered on.

[0027] In one embodiment of this utility model, such as Figure 3 , 4As shown, an isolation mechanism 6 is provided between the bottom of the light shield 2 and the silicone button 3. Specifically, the isolation mechanism 6 includes a light shield 31, which is disposed on the silicone button 3 and covers the outside of the indicator light 41. The top of the light shield 31 abuts against the bottom of the light shield 2. In addition, the light shield 31 is made of an elastic material, such as silicone. Since the light shield 31 abuts against the light shield 2, the light shield 31 can provide a rebound force to drive the light shield 2 to move upward.

[0028] In the above structure, the light shield 31 includes an inner light shield 311 and an outer light shield 312. The inner light shield 311 is a cylindrical structure, and the outer light shield 312 is located outside the inner light shield 311 and is an arc-shaped shield coaxially arranged with the inner light shield 311. The lower end of the outer light shield 312 is connected to the main body of the silicone button 3, and the upper end is connected to the upper end of the inner light shield 311. The upper end of the inner light shield 311 abuts against the bottom of the light shield 2, and the inner cavity of the inner light shield 311 is connected to the light guide groove 21. Because the upper end of the light shield 31 abuts against the light shield 2 and the lower end connects to the silicone button 3, the silicone button 3, the light shield 31, and the light guide groove 21 form a side-closed cavity. The light emitted by the indicator light 41 can only propagate within the light shield 31 and the light guide groove 21, which improves the light isolation effect. Simultaneously, an inner light shield 311 and an outer light shield 312 are provided. The inner light shield 311 is located within the cavity of the outer light shield 312, with its top end connected to the top of the outer light shield 312. The bottom end of the inner light shield 311 extends downwards into the cavity of the outer light shield 312. The inner light shield 311 will... The indicator light 41 is covered with a cylindrical cover. On the one hand, some of the light emitted by the indicator light 41 will be reflected multiple times in the inner cavity of the inner light shield 311, consuming some of the light energy. On the other hand, some of the light emitted by the indicator light 41 will be more difficult to reflect into the light guide groove 21 after entering the outer light shield 312 due to the obstruction of the inner light shield 311. Therefore, the arrangement of the inner light shield 311 and the outer light shield 312 can reduce the brightness of the light in the light guide groove 21, thereby achieving a high brightness difference between the backlight light guide area and the functional light guide area.

[0029] When button 1 is pressed down, the light shield 2 will press down the light shield 31, causing the light shield 31 to undergo elastic deformation. When the micro switch is activated, the indicator light 42 will light up. When button 1 is released, the light shield 31 will push the light shield 2 and button 1 back to their original positions under the action of elastic restoring force.

[0030] In one embodiment of this utility model, the isolation mechanism 6 further includes a light shield 32, which is disposed on the silicone button 3 and covers the outside of the indicator light 42. The upper end of the light shield 32 protrudes from the main body of the silicone button 3 and extends into the interior of the light guide groove 22. The lower end of the light guide 5 is inserted into the inner cavity of the light shield 32. The light shield 32 is made of elastic material.

[0031] Indicator light 22 is set inside the light shield 32 to further prevent light leakage. When the light guide 5 is inserted into the inner cavity of the light shield 32, the light emitted by indicator light 42 inside the light shield 32 will be guided by the light guide 5 to the light transmission area 12, thus preventing the light from indicator light 42 from being consumed in the light guide groove. This not only improves the light guiding effect of the light guide 5, but also improves the anti-light leakage effect at the lower end of the light guide groove 22.

[0032] In one embodiment of this utility model, an isolation mechanism 2 7 is provided between the top of the light shield 2 and the button 1. Specifically, the isolation mechanism 2 7 includes an isolation plate 1 24 and a light-blocking protrusion 1 131. The isolation plate 1 24 is located between the light guide groove 1 21 and the light guide groove 2 22. The isolation plate 1 24 is mounted on the light shield 2, and its upper end protrudes from the main body of the light shield 2 and extends into the interior of the inner upper shell 14. The light-blocking protrusion 1 131 protrudes from the bottom surface of the main body of the outer upper shell 13 and is adjacent to the isolation plate 1 24. The light-blocking protrusion 1 131 extends into the interior of the light guide groove 2 22. The top of the main body of the light shield 2 abuts against the bottom surface of the main body of the inner upper shell 14. The bottom surface of the main body of the inner upper shell 14 has an extension portion 143 extending into the light guide groove 1 21, and the shape of the extension portion 143 is adapted to the shape of the light guide groove. In this embodiment, the main body of the outer upper shell 13 is an arc-shaped plate at the upper end, and the main body of the inner upper shell 14 is an arc-shaped plate that overlaps with the main body of the outer upper shell 13. As can be seen from the above, the isolation plate 24 and the light-blocking protrusion 131 are both light-blocking materials, thereby isolating the light guide groove 21 and the upper end of the light guide groove 22 through the isolation mechanism 26, and preventing light leakage at the upper end.

[0033] In one embodiment of this utility model, such as Figure 1 , 4 As shown, there are multiple indicator lights 42, multiple light guide grooves 22 corresponding to the indicator lights 42 are provided on the light shield 2, multiple light shields 32 corresponding to the indicator lights 42 are provided on the silicone button 3, and an isolation mechanism 3 is provided between adjacent light guide grooves 22.

[0034] Specifically, such as Figure 1 , 4As shown in Figure 7, the isolation mechanism 3 includes an isolation plate 26 and a light-blocking protrusion 132. Isolation plates 26 are provided between adjacent light guide grooves 22. Multiple light-blocking protrusions 132 are provided on the bottom surface of the main body of the outer upper shell 13. Each light-blocking protrusion 123 corresponds to one of the isolation plates 26. The bottom end of each isolation plate 26 is connected to the inner wall of the corresponding light guide groove 22, and the top end of each isolation plate 26 extends upwards to abut against the corresponding light-blocking protrusion 132. That is, the inner walls between adjacent light guide grooves extend upwards to abut against the bottom end of the inner upper shell. In this embodiment, the light-blocking protrusion 132 is T-shaped, including a horizontal portion and a vertical portion. The horizontal portion of the light-blocking protrusion 132 overlaps with the isolation plate 26 and abuts against the top surface of the isolation plate 26. The vertical portion of the light-blocking protrusion 132 abuts against the top surface of the outer wall of the light-shielding body 2. With the setting of isolation mechanism three, there must be no light leakage between each indicator light 42 and between indicator light 42 and indicator light 41.

[0035] With the setting of isolation mechanism 1 6, isolation mechanism 2 7, and isolation mechanism 3, the light between light guide groove 1 21 and light guide groove 2 22 is isolated, preventing light leakage between light transmission area 1 11 and light transmission area 2 12, and there should be no light leakage between each indicator light 2 42 and between indicator light 2 42 and indicator light 1 41.

[0036] In one embodiment of this utility model, such as Figure 1 , 3 As shown in Figure 4, the switch button structure also includes a housing 8 and a base 9. The silicone button 3 and PCB assembly 4 are fixed on the base 9. The housing 8 covers the base 9 and the light shield 2, and the upper end of the housing 8 is inserted into the button 1. The housing 8 and the base 9 can protect the internal components of the switch and are dustproof and waterproof.

[0037] like Figure 3-4 As shown in Figures 9 and 1, the housing 8 has at least one slider 81 inside. The slider 81 is connected to the inner wall of the housing 8 via a connecting rib 82, resulting in a stable structure. The light-shielding body 2 has a groove 28 on its exterior that corresponds to the slider 81. The slider 81 and the groove 28 guide the up-and-down movement of the light-shielding body 2, making the operation more stable and smooth. In addition, the groove 28 is tapered, wider at the top and narrower at the bottom. The slider 82 and the groove 28 are compatible in shape, making it easier to align the slider 81 with the groove 28 during installation, improving installation convenience, and guiding the up-and-down movement of the light-shielding body 2, thereby ensuring stable switch triggering.

[0038] In one embodiment of this utility model, to facilitate the disassembly and assembly of the push-button switch, such as... Figure 1 , 3As shown in Figure 4, the outer shell 8 and the base 9 are connected by a snap-fit. The lower end of the outer shell 8 is provided with a snap-fit ​​plate 83. The snap-fit ​​plate 83 has openings and slots on both sides, so that there is elasticity between the snap-fit ​​plate 83 and the main body of the outer shell 8, making it easy for the snap-fit ​​91 to snap into the slot 83. The snap-fit ​​plate 83 has a slot 84 in the middle, and the outer side of the base 9 is provided with a snap-fit ​​91 that engages with the slot 84. In this embodiment, the snap-fit ​​91 is also a boss structure with a beveled surface.

[0039] like Figure 4 , 9 As shown, the housing 8 also has at least one positioning rod 85 inside. The positioning rod 85 is connected to the inner wall of the housing 8 via a connecting rib 86. The silicone button 3, PCB assembly 4, and base 9 are provided with through positioning holes. The positioning rod 85 cooperates with the positioning holes to guide the connection between the housing 8 and the base 9. In addition, the slider 81 located on the same inner wall of the housing 8 is arranged along the same straight line as the positioning rod 85, and the connecting rib 82 on the same inner wall is connected to the connecting rib 86, making the connection between the slider 81 and the positioning rod 85 more stable.
