Description

Technical Field

[0001] This utility model relates to the field of buttons, and in particular to a multi-color gradient character structure and button. Background Technology

[0002] Currently, the way to achieve color gradient effects in electronic products on the market is to print characters with gradient effects on the parts of the electronic product where the gradient effect is needed. Light shines through the characters to create a color gradient light visual effect. However, this method is only suitable for larger electronic products (such as large audio equipment). It is very difficult to print color gradient characters on smaller electronic products, such as remote control buttons and switch panel buttons.

[0003] This invention enables the buttons on smaller electronic devices to display a color gradient effect (i.e., pressing the button activates a light switch), providing users with a novel visual experience. Utility Model Content

[0004] Therefore, it is necessary to provide a multi-color gradient character structure and keypad to address the problems in the existing technology.

[0005] A multi-color gradient character structure, characterized in that it includes a PCB board, at least two LED beads are provided on the upper side of the PCB board, adjacent LED beads are spaced apart, light-guiding silicone is provided on the upper side of the LED beads, the light-guiding silicone is provided with a spacer groove, the spacer groove divides the light-guiding silicone into light-guiding parts corresponding to the LED beads, a light-shielding structure is provided at the spacer groove position to separate adjacent guide rail parts, a light-guiding button is provided on the upper side of the light-guiding silicone, the upper surface of the light-guiding button is provided with opaque paint, and light-transmitting characters are formed by partially removing the paint, the light-transmitting characters covering multiple light-guiding parts.

[0006] In one embodiment, the light-shielding structure is an opaque paint applied to the sidewalls and bottom of the spacer groove.

[0007] In one embodiment, the light-shielding structure is a light-shielding baffle inserted into the spacer slot.

[0008] In one embodiment, there are two LED beads arranged in a straight line, and there are two light guides, which are correspondingly positioned on the upper side of the LED beads.

[0009] In one embodiment, there are three LED beads arranged in a triangular pattern, including a left LED bead, a middle LED bead, and a right LED bead, and there are three light guides, each corresponding to one of the three LED beads.

[0010] In one embodiment, the light guide portion includes a left light guide portion, a middle light guide portion, and a right light guide portion corresponding to the left light bead, the middle light bead, and the right light bead, and the lower side of the middle light guide portion extends to the right of the lower light guide portion between the left light guide portion and the right light guide portion.

[0011] In one embodiment, the spacer includes a first spacer between the left light guide and the middle light guide, and a second spacer between the right light guide and the middle light guide. The first spacer has a first dividing section between the left light guide and the middle light guide, and two first branch sections that are respectively attached to two adjacent sides of the left light guide and the middle light guide. The second spacer has a second dividing section between the right light guide and the middle light guide, and two second branch sections that are respectively attached to two adjacent sides of the right light guide and the middle light guide.

[0012] In one embodiment, the light-guiding silicone is an integral structure, and the thickness of the light-guiding silicone at the bottom of the spacer groove is 0.2mm-0.4mm.

[0013] In one embodiment, the lamp bead is an RGB LED lamp bead.

[0014] A keypad characterized by employing the aforementioned multi-color gradient character structure.

[0015] The aforementioned multi-color gradient character structure and buttons separate different light-guiding parts through a light-shielding structure. This ensures that the LEDs at the bottom can only transmit light to the light-guiding button positions through their corresponding light-guiding parts. Consequently, the light-guiding buttons corresponding to the interval slots can only transmit light through adjacent light-guiding buttons, resulting in a lighter color for the corresponding translucent characters. Since the interval slots are located between two light-guiding pillars, the color of the translucent characters on the surface of the light-guiding buttons varies from dark to light to dark, thus forming gradient characters. By controlling the color of the LEDs, various gradient color effects can be created, without being limited by printing effects. Attached Figure Description

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0018] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] like Figures 1 to 3 As shown, a multi-color gradient character structure is characterized by comprising a PCB board 1, with at least two LED beads 11 on the upper side of the PCB board 1, adjacent LED beads 11 being spaced apart, a light-guiding silicone 2 on the upper side of the LED beads 11, the light-guiding silicone 2 having a spacer groove 21, the spacer groove 21 dividing the light-guiding silicone 2 into light-guiding portions 22 corresponding to the LED beads 11, a light-shielding structure being provided at the position of the spacer groove 21 for separating adjacent guide portions, a light-guiding button 3 on the upper side of the light-guiding silicone 2, the upper surface of the light-guiding button 3 having an opaque paint, which is partially removed to form a light-transmitting character 31, the light-transmitting character 31 covering multiple light-guiding portions 22.

[0021] By separating the different light guides 22 through the light-shielding structure, the LED 11 at the bottom can only transmit light to the light guide button 3 through the corresponding light guide 22. As a result, the light guide button 3 corresponding to the interval slot 21 can only transmit light through the adjacent light guide button 3, and the corresponding light-transmitting character 31 displays a lighter color. Since the interval slot 21 is located between two light guide pillars, the color of the light-transmitting character 31 on the surface of the light guide button 3 changes from dark to light to dark, thus forming a gradient color character. By controlling the color of the LED 11, a variety of gradient color effects can be formed, which is not limited by the printing effect.

[0022] The light-shielding structure at the interval slot 21 is used to block the adjacent light guide part 22 from the side, preventing the light guide part 22 from guiding light from the side. In this embodiment, the light-shielding structure is an opaque paint coated on the side wall and bottom of the interval slot 21. Specifically, black paint is used to coat the bottom and side wall of the interval slot 21. Light can only be transmitted to the light guide button 3 through the guide post, preventing light from passing through the side of the light guide post. In this way, it can be ensured that the light guide button 3 and the light-transmitting character 31 corresponding to the interval slot 21 can only transmit weak light through the top of the light guide post, and cannot be transmitted through the interval slot 21, thus forming a gradient color effect.

[0023] In another embodiment, the light-shielding structure is a light-shielding baffle inserted into the spacer slot 21. In this case, in order to avoid affecting the deformation of the light guide 22 during the pressing process, the light-shielding baffle is also made of an elastic material, such as a silicone device. Black silicone can be used, or the surface of the silicone can be coated with black paint. This can prevent light from being transmitted at the spacer slot 21 without affecting the deformation of the light guide 22.

[0024] To create a gradient color effect, at least two LED beads 11 are required, and these two LED beads 11 need to be spaced apart. Specifically, in one embodiment, two LED beads 11 are provided, arranged in a straight line, and two light guide parts 22 are provided, correspondingly positioned above the LED beads 11. In this case, with two LED beads 11 and the spacing groove 21 located between the two LED beads 11, a gradient color effect with varying shades can be created.

[0025] In one embodiment, there are three LED beads 11 arranged in a triangular pattern, including a left LED bead 111, a middle LED bead 112, and a right LED bead 113. The light guide section 22 also has three LED beads 11, distributed corresponding to the three LED beads 11. This triangular arrangement increases the overall width of the LED beads 11, thus better accommodating the larger light guide button 3. The light guide button 3 can change color both horizontally and vertically, creating a gradient color effect with varying shades.

[0026] When setting three LED beads 11, such as Figure 2and Figure 3 As shown, specifically, the light guide portion 22 includes a left light guide portion 221, a middle light guide portion 222, and a right light guide portion 22 corresponding to the left light bead 111, the middle light bead 112, and the right light bead 113. The lower light guide portion 22 of the middle light guide portion 222 extends to the right side of the lower light guide portion 221 between the left light guide portion 221 and the right light guide portion 22. At this time, the number and position distribution of the light guides 22 correspond to the lamp beads 11, and the main body of the light guides 22 is located on the upper side of the lamp beads 11. In order to form a variety of color-changing effects, the middle light guide 222 in the middle position is provided with a lower light guide 22 extending between the left light guide 221 and the right light guide 22. At this time, the lamp bead 11 corresponding to the middle light guide 222 is located on the upper main body position, and the lower light guide 22 is located on the lower side of the corresponding lamp bead 11. In this way, the light of the lower light guide 22 is slightly weaker than that of the main body of the middle light guide 222, so that a gradient color effect of light and dark can be formed on the lower side of the light guide button 3.

[0027] In order to achieve a better shielding effect through the spacer slot 21, in this embodiment, the spacer slot 21 includes a first spacer slot 23 between the left light guide 221 and the middle light guide 222, and a second spacer slot 24 between the right light guide 22 and the middle light guide 222. The first spacer slot 23 is provided with a first dividing segment 231 between the left light guide 221 and the middle light guide 222, and two first branch segments 232 respectively attached to two adjacent sides of the left light guide 221 and the middle light guide 222. The second spacer slot 24 is provided with a second dividing segment 241 between the right light guide 22 and the middle light guide 222, and two second branch segments 242 respectively attached to two adjacent sides of the right light guide 22 and the middle light guide 222. The first dividing segment 231 is used to separate the two adjacent left light guides 221 and the middle light guide 222. However, at this time, the left light guide 221 and the middle light guide 222 still have two sides that are close to each other. If the two sides are not separated, light transmission will also be affected. Therefore, the left light guide 221, the middle light guide 222, and the right light guide 22 are separated by the first branch segment 232 and the second branch segment 242. At this time, the first branch segment 232 and the second branch segment 242 are each provided with two side branches, that is, the left light guide 221, the middle light guide 222, and the right light guide 22 are completely separated by the first interval groove 23 and the second interval groove 24.

[0028] The light-guiding silicone 2 is formed by multiple light-guiding parts 22. To ensure that the light-guiding silicone 2 is an integral structure during the pressing of the light-guiding button 3, the thickness of the light-guiding silicone 2 at the bottom of the spacing groove 21 is 0.2mm-0.4mm. Specifically, the thickness of the light-guiding silicone 2 at the bottom of the spacing groove 21 is 0.25mm. That is, the thickness at the bottom of the spacing groove 21 is relatively small, and when all the light-guiding pillars are connected together, the impact on color bleeding is small.

[0029] To achieve different display effects, in this embodiment, the LED bead 11 is an RGB LED bead 11. Thus, different colors of the LED bead 11 create different gradient color display effects during the display process.

[0030] In another embodiment, a button is included, characterized by employing the multi-color gradient character structure described in the above embodiments. In this case, the button can be used as a remote control or switch button, thereby forming a remote control or switch with a gradient color display effect. Of course, when the gradient character structure is applied to the button, other structures of the button adopt existing technical solutions, and therefore will not be described in detail here.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
