Description

Technical Field

[0001] This utility model relates to the field of switch technology, and in particular to a push-button switch. Background Technology

[0002] Switches are used in many places nowadays; for example, various push-button switches are used in automobiles. Push-button switches generally have indicator lights, typically two different types: a backlight and a function light. The backlight primarily indicates the button's position, while the function light indicates whether the button is in the "on" state. Due to their different functions, the brightness of the backlight and function light differs significantly; the function light reaches a brightness of 1300 cd / m². 2 It is about 220 times brighter than a backlight.

[0003] In existing technologies, the light-transmitting areas of indicator lights one and two are typically made using two different light-transmitting materials, along with a substrate to support these areas. This requires the use of a 3K injection molding process when manufacturing the buttons. This manufacturing process is costly and inefficient.

[0004] Furthermore, existing technologies for preventing light leakage are ineffective, and light leakage can occur in situations with high brightness. Since there is a significant brightness difference between the backlight and function lights' light-transmitting areas, a design to prevent light leakage between the two types of lights is necessary to prevent interference and malfunctions.

[0044] 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.

[0045] In one embodiment of this utility model, such as Figure 1-9 As shown, a push-button switch includes:

[0046] Button 1, with a light-transmitting area 11 and a light-transmitting area 12 on its top surface; light shield 2, located at the lower end of button 1, with a light guide groove 21 and a light guide groove 22 inside, and a light guide 5 inside the light guide groove 22; silicone button 3, located between the light shield 2 and PCB assembly 4; PCB assembly 4, located below the light shield 2, with an indicator light 41 and an indicator light 42 on the PCB assembly 4, the indicator light 41 corresponding to the light-transmitting area 11 at both ends of the light guide groove 21, and the indicator light 42 corresponding to the light-transmitting area 212 at both ends of the light guide groove 22;

[0047] The silicone button 3 is provided with an isolation mechanism 6, which is at least partially located between indicator light 41 and indicator light 42 to achieve light isolation between indicator light 41 and indicator light 42.

[0048] In some embodiments of this utility model, indicator light 1 41 and indicator light 2 42 are respectively a backlight and a function light, and light-transmitting area 1 11 and light-transmitting area 2 12 are respectively the light-transmitting area of ​​the backlight and the light-transmitting area of ​​the function light, but it is not limited to this, and the switching of both types of indicator lights is applicable.

[0049] In one embodiment of this utility model, a light guide 5 is provided in the second light guide groove 22, while no light guide is provided in the first light guide groove 21. When the first indicator light 41 and the second indicator light 42 are lit, the light emitted by the first indicator light 41 is guided to the first light-transmitting area 11 through the first light guide groove 21, and the light emitted by the second indicator light 42 is guided to the first light-transmitting area 11 through the second light guide groove 22 and the light guide 5. The first indicator light 41 will be reflected in the first light guide groove 21, and part of the light from the first indicator light 41 cannot be guided to the first light-transmitting area 11. The second light guide groove 22 is provided with a light guide 5. The light guide 5 guides most of the optics of indicator light 42 to the light-transmitting area 12. Therefore, there will be a difference in brightness between the light-transmitting area 11 and the light-transmitting area 12. The brightness of the light-transmitting area 12 will be significantly higher than that of the light-transmitting area 12. This satisfies the brightness difference between the backlight light-transmitting area and the function light light-transmitting area. The light guide groove 121 and the light guide groove 22 are light-isolated by the isolation mechanism 6, thereby achieving a high brightness difference effect between indicator light 41 and indicator light 42, and the lights of the two do not affect each other.

[0050] In one embodiment of this application, such as Figure 1 , 3 As shown in Figure 6, 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 and is fixedly connected to the inner upper shell 14.

[0051] Specifically, 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 all made of light-transmitting plastic material. 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 the first indicator light 41 and the second indicator light 42 are not lit, the first light-transmitting area 11 and the second light-transmitting area 12 have the same color. When the first indicator light 41 and the second indicator light 42 are lit, due to the large difference in brightness, the first light-transmitting area 11 and the second light-transmitting area 12 exhibit different brightness.

[0052] 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.

[0053] In one embodiment of this utility model, such as 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. The lower end of the inner upper shell 14 has an extension plate 141 extending into the light-shielding body 2. The extension plate 141 has a slot 142. Inside the light-shielding body 2, there is a buckle 23 corresponding to the slot 142, which engages with the slot 142. In this embodiment, the buckle 23 is a boss structure with a beveled surface. The engagement of the buckle 23 and the slot 142 improves the overall stability and waterproof performance of the switch.

[0054] 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, i.e., the function light, thus illuminating the second silicone button in the light-transmitting area 12. The light shield 31 of the silicone button 3 can provide a rebound force to drive 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. The first indicator light, i.e., the backlight, is in a constant-on mode after the car is powered on.

[0055] In one embodiment of this utility model, such as Figure 3-4 As shown, the isolation mechanism 6 includes a light shield 31, which is mounted 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. Furthermore, the light shield 31 is made of an elastic material, such as silicone. Because the light shield 31 abuts against the light shield 2, it provides a rebound force that drives the light shield 2 to move upwards.

[0056] 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. The outer light shield 312 is an arc-shaped cover 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 by 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 blocked by the inner light shield 311 after entering the outer light shield 312, making it more difficult to reflect into the light guide groove 21. 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.

[0057] 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.

[0058] 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.

[0059] Indicator light 2 42 is set in the inner cavity of light shield 32, which can further prevent light leakage. When light guide 5 is inserted into the inner cavity of light shield 2 32, the light emitted by indicator light 2 42 will be guided by light guide 5 to light transmission area 2 12 inside light shield 2 32, thus preventing the light of indicator light 2 42 from being consumed in light guide groove 2 22. While improving the light guiding effect of light guide 5, it can also improve the anti-light leakage effect at the lower end of light guide groove 2 22.

[0060] In one embodiment of this utility model, such as Figure 3 As shown, an isolation mechanism 2 7 is provided between the top of the light shield 2 and the button 1. 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 set on the light shield 2, and the upper end of the isolation plate 1 24 protrudes out of 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 arranged 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 143 extending into the light guide groove 1 21, and the shape of the extension 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. Since the isolation plate 24 and the light-blocking protrusion 131 are both light-blocking materials, the upper end of the light guide groove 21 and the upper end of the light guide groove 22 are isolated by the isolation mechanism 6, thus preventing light leakage at the upper end.

[0061] 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.

[0062] like Figure 1 , 4As shown in Figure 7, the isolation mechanism three includes an isolation plate 26 and a light-blocking protrusion 132. An isolation plate 26 is 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. Multiple light-blocking protrusions 123 are correspondingly arranged with 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 upward to abut against the corresponding light-blocking protrusion 132. 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 shield 2. Through the arrangement of the isolation mechanism three, there should be no light leakage between the indicator lights 2 42 and between the indicator lights 2 42 and the indicator lights 1 41.

[0063] In one embodiment of this utility model, such as Figure 1 , 3 As shown in Figure 8, the light guide 5 is fixedly connected to the light shield 2. The light guide 5 has multiple positioning protrusions 51 on its exterior. Each positioning protrusion 51 abuts against the inner wall of the light guide groove 22. Each positioning protrusion 51 has an inclined guide surface. 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 adapted to the positioning step 27, and the top of the positioning protrusion 52 abuts against one side of the positioning step 27. During installation, 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 within the light guide groove 22. The light guide 5 is then fixedly connected to the light shield 2 by means of bonding or other methods.

[0064] In one embodiment of this utility model, such as Figure 1 , 3 As shown in Figure 4, the aforementioned push button switch also includes a housing 8 and a base 9. The silicone button 3 and the 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.

[0065] In one embodiment of this utility model, as follows: Figure 3-4As shown in Figures 9 and 1, the outer casing 8 has at least one slider 81 inside. The slider 81 is connected to the inner wall of the outer casing 8 via a connecting rib 82, resulting in a stable structure. The light-shielding body 2 has a sliding groove 28 on its exterior, corresponding to the slider 81. The slider 81 and the sliding groove 28 guide the up-and-down movement of the light-shielding body 2, making the operation more stable and smooth. In addition, the sliding groove 28 is tapered, wider at the top and narrower at the bottom. The slider 82 and the sliding groove 28 are compatible in shape, making it easier to align the slider 81 with the sliding 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.

[0066] To facilitate the installation and removal of push-button switches, such as Figure 1 , 3 As 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.

[0067] In one embodiment of this utility model, as follows: 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 have 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.
