Abstract
Description
Technical Field
[0001] This utility model belongs to the field of button technology, and specifically relates to a light-emitting button. Background Technology
[0002] An illuminated button is a push-button switch with an LED light that typically illuminates or flashes when pressed or released. Backlit buttons can be made to reflect the effect of the light on the button. Backlit buttons have a wide range of applications, such as computer keyboards, electric vehicle buttons, and game consoles. The purpose of backlit buttons is not only aesthetics but, more importantly, to provide a convenient user experience. Whether at night or in dimly lit environments, users can easily identify and use the buttons, improving their quality of life and work. The working principle of an illuminated button is to embed an LED light inside the button. When the button is pressed, the LED light illuminates; when the button is released, the LED light may turn off or continue to flash to indicate the button's status or provide other information.
[0003] However, illuminated buttons typically use one or several symmetrically arranged LEDs on a circuit board to provide light to the button. When using a single LED, because the LED is positioned around the button and doesn't directly illuminate it, the light distribution on the button's surface becomes uneven. Using multiple symmetrical LEDs, on the other hand, wastes light. While light intensity can be enhanced by reflecting the light from the LEDs through a light guide channel, this intensity remains relatively weak in very dim environments. Utility Model Content
[0004] This utility model discloses a light-emitting button, which aims to solve the technical problem in the prior art where the light intensity provided by a single LED is weak.
[0005] To solve the aforementioned technical problems, the present invention adopts the following technical solution:
[0006] A backlit button includes a light-transmitting keycap and a circuit board connected to a switch and an LED. The LED is disposed on the side wall of the switch. The switch is provided with a light intensity amplification device that cooperates with the LED. The light intensity amplification device includes a light-collecting element disposed on the switch to collect the light emitted by the LED. The light-collecting element is provided with a light-collecting device. The light-collecting element is inclined to the switch. The light emitted by the LED is focused by the light-collecting element and enters the keycap to provide backlighting for the keycap.
[0007] With this technical solution, the switch soldered onto the circuit board includes a pressing structure and a base, with the LED bead positioned on the side wall of the switch. A light-collecting component is installed on the switch on the circuit board, positioned parallel to the switch and the LED bead, and tilted relative to the switch. This allows the light-collecting component to be at a certain angle to the LED bead. When the LED bead starts emitting light, the light emitted by the LED bead forms a certain incident angle with the light-collecting device of the light-collecting component. The light diffracts within the light-collecting device, and the diffracted exit direction is towards the backlight surface of the keycap, providing a backlight source for the keycap. Because the light from the LED bead is collected, compared to the traditional method of directly providing a light source for the keycap through the scattered light of the LED bead, this device enhances the light intensity, making the keycap brighter. Even with a single LED bead, a stable and bright light source can be provided.
[0008] The light-collecting component is disposed on the pressing part of the switch, and the light-collecting device includes a convex structure disposed on the light-collecting component. The protrusion of the convex structure is disposed away from the circuit board. When the pressing part of the switch is pressed, the light emitted by the LED bead is diffracted by the convex structure and enters the keycap.
[0009] With this technical solution, the light-collecting component and the switch are tilted, so that the convex structure on the light-collecting component can also form a certain angle with the LED bead. This allows most of the light emitted by the LED bead to enter the convex structure at certain incident angles and be diffracted into the keycap, providing a backlight source for the keycap. The convex structure itself has the function of collecting light, which can have a better light-gathering effect and make the button reminder effect better.
[0010] The switch is fitted with a flexible protective sleeve, the shape and size of which match the shape and size of the switch, and the light-collecting component is located on the side of the flexible protective sleeve away from the circuit board.
[0011] By adopting this technical solution, the flexible protective sleeve can protect the switch, extend its lifespan, reduce costs, and improve the tactile feel when pressed. Furthermore, by placing the light-collecting component on the side of the flexible protective sleeve furthest from the circuit board, the component, connected to the flexible protective sleeve, moves closer to the LED beads vertically after the switch is pressed, collecting more light from the LEDs and resulting in brighter, more easily identifiable backlighting on the keycaps.
[0012] The light intensity enhancement device further includes a mounting ring sleeved on the top of the switch, and the light collecting component is provided with a retaining ring that cooperates with the mounting ring.
[0013] After adopting this technical solution, the installation ring and retaining ring simplify the connection between the switch and the light intensity enhancement device, making the connection between the switch and the light intensity enhancement device easier and the production operation simpler.
[0014] The keycap is provided with a trigger element, the trigger key is located at the center of the keycap, and the keycap is also provided with a first sleeve, which is sleeved on the outside of the trigger element, and the trigger element is in contact with the switch.
[0015] After adopting this technical solution, the setting of the first sleeve and the trigger can not only enable the keycap to cooperate with other structures, such as being set on other devices through brackets and housings, such as the handlebars of electric vehicles, so that the keycap has the feel of contacting the switch when pressed down, but also enable the light source to provide light to the keycap through the gap between the trigger and the first sleeve, so that the keycap can achieve a backlight effect.
[0016] The trigger is a light guide post, which has a cross structure, and the gap between the light guide post and the inner wall of the first sleeve is a light guide groove.
[0017] With this technical solution, the light from the LED can reach the keycap surface through the gap between the light guide post and the first sleeve, softening the light source and improving the visual effect of the illuminated button.
[0018] The keycap is also connected to a light guide ring, which is made of a semi-transparent material and has a through hole that mates with the first sleeve. The light guide ring and the keycap are detachably connected.
[0019] With this technical solution, the light guide ring can be used in two ways: firstly, it can work with other supports to provide pressing space for the keycaps; secondly, it can work with the keycaps to create a light ring between the keycaps and the side wall of the light guide ring, making the boundary of the illuminated button easier to identify, thereby improving the comfort of using the illuminated button.
[0020] The through hole is provided with a connecting block, the outer wall of the first sleeve is provided with a connecting groove that mates with the through hole, the inner wall of the through hole is also provided with an elastic element, the outer wall of the first sleeve is provided with an elastic groove that mates with the elastic element, and the top of the light guide ring is also provided with an annular groove that allows the keycap to slide.
[0021] By adopting this technical solution, the connecting block, connecting groove, and elastic components not only make the connection between the keycap and the light guide ring more stable, improving the stability of the device during use, but also improve the feel of the keycap when pressed, thus enhancing the user experience.
[0022] The keycaps are made of a semi-transparent material, and the top surface of the keycaps is provided with a spray-painted laser engraving layer. The keycaps are also provided with characters and a halo.
[0023] With this technical solution, the keycaps are made of semi-transparent material, with a spray-painted laser engraving layer and characters. Under the premise of more uniform keycap illumination, the characters and halo make the buttons more visible and easier to identify in dark environments.
[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0025] (1) By using light-collecting components, the light emitted by the LED beads is concentrated, making the light reflected to the keycap stronger, thus making the light-emitting button more obvious. One LED bead can also achieve a strong light-emitting effect, saving costs.
[0026] (2) Using silicone protective sleeves, etc., not only protects the switch and extends its service life, but also causes the silicone protective sleeve to deform naturally when the switch is pressed, so that the distance between the light collector and the lamp bead is closer and more light is collected, making the light effect of the button more obvious.
[0027] (3) By using light guide pillars, light guide grooves, etc., the light from the LED beads can reach the surface of the keycap through the gap between the light guide pillars and the first sleeve, softening the light source and improving the visual effect of the illuminated button.
[0028] (4) Using light guide rings, etc., can be used in conjunction with other brackets to provide pressing space for keycaps. On the other hand, it can be used in conjunction with keycaps to create a light ring between the keycaps and the side wall of the light guide ring, making the boundary of the illuminated button easier to identify, thereby improving the comfort of using the illuminated button.
[0029] (5) By using spray paint and laser engraving layers, the keycaps are illuminated more evenly, and the characters and halos make the buttons more visible and easier to identify in the dark. Attached Figure Description

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0039] The following is combined Figures 1-4 This utility model will be described in detail. Example 1
[0040] A type of illuminated button, such as Figures 1-4 As shown, the keycap 1 is light-transmitting and the circuit board 9 is connected to the switch 6 and the LED 8. The LED 8 is disposed on the side wall of the switch 6. The switch 6 is provided with a light intensity amplification device that cooperates with the LED 8. The light intensity amplification device includes a light-collecting element 7 disposed on the switch 6 to collect the light emitted by the LED 8. The light-collecting element 7 is provided with a light-collecting device. The light-collecting element 7 is inclined to the switch 6. The light emitted by the LED 8 is focused by the light-collecting element 7 and enters the keycap 1 to provide backlight to the keycap 1.
[0041] In this embodiment, the circuit board 9 is a PCB circuit board 9, and the lamp bead 8 is an LED surface mount packaged lamp bead 8.
[0042] In this embodiment, the LED bead 8 is disposed on the side wall of the switch 6, and the vertical distance between the LED bead 8 and the side of the base of the switch 6 is 5mm.
[0043] In this embodiment, the LED bead 8 is a diffused light LED bead 8. While the luminous intensity of the diffused light LED bead 8 is relatively low, its beam angle is large, reaching over 120 degrees, resulting in a wide illumination range and uniform light emission. Using a diffused light LED bead 8 ensures uniform illumination of the illuminated button.
[0044] In this embodiment, the keycap 1 is made of a light-transmitting material such as ABS. ABS is a commonly used material for light-transmitting keycaps 1 due to its high transparency and gloss. The ABS keycap 1 allows the light from the LED beads 8 to pass through the keycap 1 without obstruction, resulting in a better indicator effect.
[0045] In this embodiment, the light-collecting component 7 is a transparent plastic sheet with a light-collecting device. The plastic sheet has good toughness and flexibility, allowing it to bend at a certain angle. Initially, the light-collecting component 7 is tilted relative to the switch 6, so that the transparent plastic sheet forms an angle with the light emitted by the LED bead 8, collecting the scattered light. Tilting the light-collecting component 7 does not affect the contact between the switch 6 and the keycap 1. In other embodiments, the light-collecting device may not be necessary on the light-collecting component 7; it is sufficient to ensure that the incident angle between the light emitted by the LED bead 8 and the light-collecting component 7 meets the diffraction requirements, allowing the light to be diffracted so that its direction is parallel to the direction of the keycap 1. In other embodiments, a microcurrent can be initially provided to the LED bead 8, causing it to emit a faint glow, making the device more easily identifiable in dark environments. As the switch 6 is gradually pressed down, the distance between the light-collecting component 7 and the LED bead 8 decreases, collecting more and more light, causing the device to brighten beyond its initial faint glow, alerting the user that the button has been pressed.
[0046] The switch 6, soldered onto the circuit board 9, includes a pressing structure and a base. LED beads 8 are disposed on the side wall of the switch 6. A light-collecting component 7 is mounted on the switch 6 on the circuit board 9, positioned parallel to the switch 6 and LED beads 8, and tilted relative to the switch 6. This allows the light-collecting component 7 to maintain an angle with the LED beads 8. When the LED beads 8 begin to emit light, the light emitted by the LED beads 8 forms a certain incident angle with the light-collecting device of the light-collecting component 7. The light diffracts within the light-collecting device, and the diffracted exit direction is towards the backlight surface of the keycap 1, providing a backlight source for the keycap 1. Because the light from the LED beads 8 is collected, compared to the traditional method of directly providing a light source to the keycap 1 through the scattered light of the LED beads 8, this device enhances the light intensity, making the keycap 1 brighter. Even a single LED bead 8 can provide a stable and bright light source.
[0047] In this embodiment, the light-collecting component 7 is disposed on the pressing part of the switch 6, and the light-collecting device includes a convex structure disposed on the light-collecting component 7. The protrusion of the convex structure is disposed away from the circuit board 9. When the pressing part of the switch 6 is pressed, the light emitted by the LED bead 8 enters the keycap 1 after being diffracted by the convex structure.
[0048] In this embodiment, the light-collecting component 7 and the switch 6 are inclined, so that the convex structure on the light-collecting component 7 can also form a certain angle with the LED bead 8. This allows most of the light emitted by the LED bead 8 to enter the convex structure at certain incident angles and be diffracted into the keycap 1, providing a backlight source for the keycap 1. The convex structure itself has a light-collecting function, which can have a better light-gathering effect and improve the button's reminder effect. In other embodiments, the housing device can be configured as several cavities within the light-collecting component 7. Through this cavity structure, the light-collecting component 7 becomes a planar structure with concave and convex structures, which can further increase the light-gathering effect.
[0049] In this embodiment, a flexible protective sleeve 5 is provided on the switch 6. The shape and size of the flexible protective sleeve 5 are matched with the shape and size of the switch 6. The light-collecting component 7 is disposed on the side of the flexible protective sleeve 5 away from the circuit board 9.
[0050] In this embodiment, the flexible protective sleeve is made of silicone. Silicone has a certain hardness and a certain softness, which can deform when the switch 6 is pressed. After the switch 6 is reset, the deformation disappears, so that it can cooperate with the light collector 7, so that the light collector 7 can rotate around the connection point with the silicone sleeve within a certain range. This allows the light collector 7 to change the angle and relative position between itself and the lamp bead 8 during the process of the switch 6 being pressed, so as to collect the light emitted by the lamp bead 8.
[0051] In this embodiment, the distance between the light-collecting component 7 and the top of the flexible protective sleeve 5 is 2mm.
[0052] In this embodiment, the silicone protective sleeve includes a prism ring that mates with the base. A hollow frustum is provided on the top of the prism ring. The larger diameter side of the hollow frustum is connected to the prism ring. The hollow frustum communicates with the prism ring. A cylinder that mates with the pressing structure of switch 6 is provided inside the hollow frustum.
[0053] In this embodiment, the flexible protective sleeve 5 protects the switch 6, extends its service life, reduces costs, and improves the tactile feel when pressed. By placing the light-collecting component 7 on the side of the flexible protective sleeve 5 away from the circuit board 9, after the switch 6 is pressed, the light-collecting component 7 connected to the flexible protective sleeve 5 is positioned closer to the LED beads 8 in the vertical direction, collecting more light from the LED beads 8, making the backlight of the keycap 1 brighter and easier to identify.
[0054] In this embodiment, a trigger element 4 is provided on the keycap 1, the trigger key is located at the center of the keycap 1, and a first sleeve 3 is also provided on the keycap 1. The first sleeve 3 is sleeved on the outside of the trigger element 4, and the trigger element 4 is in contact with the switch 6.
[0055] In this embodiment, both the keycap 1 and the first sleeve 3 are made of a semi-transparent material, such as PET. PET has high light transmittance, impact resistance, and weather resistance, with overall performance between acrylic and PC. PET light guide plates perform well in terms of display effect and impact resistance, and are relatively inexpensive. Alternatively, a semi-transparent film can be attached to ABS material to achieve a softer light from the illuminated buttons.
[0056] The first sleeve 3 and the trigger 4 are designed to allow the keycap 1 to work with other structures, such as mounting it on other devices, like the handlebars of an electric vehicle, through a bracket or housing, so that the keycap 1 can be pressed down to make contact with the switch 6. On the other hand, the first sleeve 3 and the trigger 4 are designed to allow the light source to provide light to the keycap 1 through the gap between the trigger 4 and the first sleeve 3, so that the keycap 1 can achieve a backlight effect.
[0057] In this embodiment, the trigger 4 is a light guide post with a cross structure, and the gap between the light guide post and the inner wall of the first sleeve 3 is a light guide groove.
[0058] In this embodiment, the light-collecting element 7 is disposed on the side wall of the flexible protective sleeve 5. Furthermore, the light-collecting element 7 is inclined to the flexible protective sleeve 5. Therefore, the light-collecting element 7 does not affect the contact between the trigger key 4 and the switch 6, and because the light-collecting element 7 itself has a curved structure, the trigger key 4 will not contact the surface of the light-collecting element 7 when it contacts the switch 6. Therefore, the trigger key 4 and the first sleeve 3 will not affect the use of the light-collecting element 7.
[0059] In this embodiment, the light guide post is made of PC material, which has high transparency, high toughness, and good heat resistance. Setting the trigger element 4 as a cross structure increases the number of light reflections in the light guide groove, resulting in more light reaching the keycap 1, making the light denser and the luminous effect of the keycap 1 softer.
[0060] The light from the LED bead 8 can reach the surface of the keycap 1 through the gap between the light guide post and the first sleeve 3, softening the light source and improving the visual effect of the illuminated button.
[0061] In this embodiment, the keycap 1 is made of a semi-transparent material, the top surface of the keycap 1 is provided with a spray-painted laser engraving layer, and the keycap 1 is provided with characters 101 and a halo 102.
[0062] In this embodiment, both the character 101 and the halo 102 are formed using laser technology.
[0063] The keycap 1 uses a semi-transparent material, a spray-painted laser engraving layer, and laser-engraved characters 101. With the keycap 1 having more uniform illumination, the laser-engraved characters 101 and laser halo 102 make the button more visible and easier to identify in the dark.
[0064] In this embodiment, the keycap 1 is also connected to a light guide ring 2. The light guide ring 2 is made of a semi-transparent material and has a through hole that cooperates with the first sleeve 3. The light guide ring 2 and the keycap 1 are detachably connected.
[0065] In this embodiment, the light guide ring 2 is also made of PET material.
[0066] In this embodiment, the light guide ring 2 can be used with electric vehicle panels, electrical appliance panels, etc., and the light guide ring 2 and keycap 1 can be installed on the surface of these devices by means of adhesion, threaded connection, or snap-fit followed by adhesion.
[0067] In this embodiment, the through hole is integrally formed with the light guide ring 2, the light guide ring 2 is disposed below the keycap 1, and a gap of 0.1mm is left between the light guide ring 2 and the keycap 1.
[0068] The light guide ring 2 serves two purposes: firstly, it can cooperate with other supports to provide pressing space for the keycap 1; secondly, it can cooperate with the keycap 1 to create a light ring between the keycap 1 and the side wall of the light guide ring 2, making the boundary of the illuminated button easier to identify, thereby improving the user comfort of the illuminated button. In other embodiments, three through holes can be directly set on the light guide ring 2 to cooperate with three buttons.
[0069] In this embodiment, a connecting block 2021 is provided inside the through hole, a connecting groove 301 that mates with the through hole is provided on the outer side wall of the first sleeve 3, an elastic element is also provided on the inner side wall of the through hole, an elastic groove 302 that mates with the elastic element is provided on the outer side wall of the first sleeve 3, and an annular groove 201 that allows the keycap 1 to slide is also provided on the top of the light guide ring 2.
[0070] In this embodiment, a second sleeve 202 is provided inside the through hole. The second sleeve 202 is sleeved on the outer wall of the first sleeve 3. The length of the connecting block 2021 is equal to the length of the first sleeve 3. The length of the connecting groove 301 is equal to the length of the first sleeve 3.
[0071] In this embodiment, the height of the second sleeve 202 is 1 cm higher than the top surface of the light guide ring 2.
[0072] In this embodiment, the elastic element includes wedge-shaped blocks symmetrically disposed on both sides of the through hole. A wedge-shaped groove is provided within the through hole to accommodate the wedge-shaped blocks, and the wedge-shaped groove and the wedge-shaped blocks are connected by a spring. The cooperation between the wedge-shaped blocks and the elastic groove 302 is well-known technology and will not be elaborated upon here.
[0073] The connecting block 2021, connecting groove 301, and elastic components not only make the connection between the keycap 1 and the light guide ring 2 more stable, improving the stability of the device during use, but also improve the feel of the keycap 1 when pressed, enhancing the user experience.
[0074] The specific method of using this utility model is as follows:
[0075] Reference Figures 1-4 When using this device, first install all components so that the keycap 1, light guide ring 2, switch 6, and circuit board 9 are in a vertical position, and then supply power to the circuit board 9.
[0076] Then, pressing the keycap 1 causes the trigger 4 inside the key slot to contact the pressing part of the switch 6. Pressing the pressing part of the switch 6 connects the circuit and supplies power to the LED bead 8, causing the LED bead 8 to emit light. The light-collecting component 7 on the flexible protective sleeve is a thin transparent plastic sheet with a convex structure. The convex structure is far from the circuit board 9, so it can collect the light emitted by the LED bead 8. When the LED bead 8 starts to emit light, the light emitted by the LED bead 8 can form a certain incident angle with the light-collecting device of the light-collecting component 7. The light diffracts in the light-collecting device, and the diffracted exit direction is the backlight surface of the keycap 1, providing a backlight source for the keycap 1. At the same time, in conjunction with the light guide post and light guide groove, since the keycap 1, the first sleeve 3, and the light guide ring 2 are all semi-transparent devices, the surface of the keycap 1 and the area between the light guide ring 2 and the keycap 1 can all emit light, serving as a prompt. Meanwhile, because keycap 1 also has a spray-painted laser engraving layer, laser-engraved characters 101 and laser-engraved halo 102, only the characters 101, halo 102 and side gaps on keycap 1 are illuminated, serving as a reminder. Example 2
[0077] This embodiment is basically the same as embodiment 1, except that: in this embodiment, the light intensity enhancement device further includes a mounting ring sleeved on the top of the switch 6, and the light collecting component 7 is provided with a retaining ring that cooperates with the mounting ring.
[0078] In this embodiment, the mounting ring is a silicone ring, and the mounting ring is interference-fitted with the pressing structure of the switch 6. When in use, the mounting ring can be directly sleeved onto the pressing structure.
[0079] In this embodiment, a collar is attached to the mounting ring, and the collar is perpendicular to the retaining ring. The collar and the retaining ring allow the light-collecting component 7 to rotate around the collar.
[0080] The installation ring and retaining ring simplify the connection between switch 6 and the light intensity enhancement device, making the connection between switch 6 and the light intensity enhancement device easier and simplifying production operations.
