Description

Technical Field

[0001] This solution relates to the field of touch button technology, and in particular to a touch button. Background Technology

[0002] In existing technologies, most buttons are mechanical in structure. These mechanical buttons have several drawbacks. Firstly, their size is often limited by the mechanical structure, making further miniaturization difficult while maintaining functionality. The heat sink requires significant space, and the limited installation space makes installing mechanical buttons extremely difficult. Secondly, mechanical buttons are prone to malfunction during long-term use due to frequent contact and friction between mechanical parts, leading to a shortened lifespan. Furthermore, the installation of mechanical buttons requires a relatively complex mechanical assembly process, increasing production and maintenance costs.

[0003] Therefore, there is an urgent need for a button that is easier to install and takes up less space. Summary of the Invention

[0004] To address the aforementioned issues, this solution provides a touch-sensitive button.

[0005] To achieve the above objectives, the technical solution adopted in this solution is: a touch button, including a button body, the button body including a touch terminal and a cavity, the button body sealing the cavity with potting glue, and the cavity being provided with a PCB board, a light guide plate and a light shielding film from the outside to the inside.

[0006] Furthermore, the cavity and the touch terminal are integrally formed, forming an waist-shaped structure with symmetrical buckles on the sides.

[0007] Furthermore, the latch forms an obtuse angle on the outside of the cavity, and the side of the latch near the touch terminal includes an anti-slip structure.

[0008] Furthermore, the light-shielding film, light guide plate, and PCB board are fixed inside the cavity with epoxy adhesive.

[0009] Furthermore, the touch terminal has a circular structure with a silicone pad embedded in the middle.

[0010] Furthermore, the silicone pad is made of highly transparent silicone material.

[0011] Furthermore, the silicone pad corresponds to the PCB board below it.

[0012] Furthermore, the PCB board is located above the light guide plate, and the PCB board integrates a touch module, including a touch sensor and related control circuitry.

[0013] Furthermore, the light guide plate is disposed above the light-shielding film, and the light guide plate is made of acrylic material.

[0014] Furthermore, the light-shielding film is located in the innermost layer of the button body cavity, and is made of black PET material with a thickness between 0.05-0.2mm.

[0015] In summary, this solution has the following advantages:

[0028] The present solution will be further described below with reference to the accompanying drawings and embodiments:

[0029] Example 1:

[0030] A touch-sensitive button for connecting to and adjusting the fan speed includes a button body 1, such as... Figure 1 and Figure 2 As shown, the button body 1 is sealed with a PCB board 2, a light guide plate 3, and a light shielding film 4 within a potting cavity 12.

[0031] The button body 1 includes a touch terminal 11 and a cavity 12. Pressing the touch terminal 11 through the through hole adjusts the fan speed and status.

[0032] The touch terminal 11 has a circular structure and is integrally formed with the cavity 12. A silicone pad 111 is embedded in the middle, which can provide obvious touch feedback and has good insulation performance, effectively avoiding the risk of short circuit.

[0033] The silicone pad 111 is made of highly transparent silicone material to ensure that the light from the internal light-emitting element can pass through clearly without affecting the logo display effect.

[0034] The touch sensor on the PCB board 2 below the touch terminal 11 adopts capacitive or pressure sensing technology, which is highly sensitive and responds quickly. It can quickly convert touch signals into electrical signals, and after analysis by the control circuit, accurately control the device.

[0035] The cavity 12 has an overall waist-shaped structure with symmetrically arranged buckles 121 on its sides. The buckles 121 form an obtuse angle on the outer side of the cavity 12. This obtuse angle design allows the buckles 121 to smoothly guide and self-position themselves when inserted into the pre-set slots on the edge of the contoured holes in the heat sink panel, thanks to their tilt angle. The side of the buckle 121 near the touch terminal 11 includes an anti-slip structure 1211, which better serves to limit the movement.

[0036] The cavity 12 structure of the button body 1 can precisely fit the contoured holes on the heat sink panel, effectively avoiding any shaking or displacement that may occur during installation. During assembly, simply push the cavity 12 into place along the specific direction of the contoured holes to quickly complete the installation, significantly improving assembly efficiency and reducing time wasted due to installation difficulties. Furthermore, the waist-shaped design provides significant error-proofing. When the button body 1 is installed on the heat sink panel, its logo orientation remains correct, avoiding misalignment caused by incorrect installation.

[0037] The cavity includes a PCB board 2, a light guide plate 3 and a light-shielding film 4 from the outside to the inside, and the light-shielding film 4 is close to the touch terminal 11.

[0038] The PCB board 2, serving as the core circuit carrier for the button, is located above the light guide plate 3. The PCB board 2 integrates a touch module, including a touch sensor and related control circuitry. The touch sensor detects user touch operations; when the user touches the button surface, the touch sensor quickly converts the touch signal into an electrical signal, which is then processed and transmitted by the control circuitry to control devices such as the heat sink. Simultaneously, the PCB board 2 also integrates a driving circuit for the light-emitting element, used to control the brightness and color changes of the light-emitting element to indicate whether the button is on, off, or in different operating modes.

[0039] The light guide plate 3 is positioned above the light-shielding film 4. The main function of the light guide plate 3 is to uniformly scatter and guide the light from the light-emitting elements on the PCB board 2. Through the action of the light guide plate 3, the light emitted from the PCB board 2 can more evenly illuminate the logo area on the front of the button, further enhancing the logo's display effect and giving the button surface a uniform and soft luminous effect, thus improving the product's visual appeal and user experience. The light guide plate 3 is typically made of acrylic material.

[0040] The light-shielding film 4 is located at the innermost layer inside the cavity 12 of the button body 1, ensuring that the logo is clearly displayed on the front of the button. When the light-emitting element on the PCB board 2 emits light, the light-shielding film 4 effectively blocks stray light except that passing through the logo area, allowing light to pass through only the specific logo area on the front of the button body 1. This ensures that the logo is clearly and prominently displayed on the touch terminal 11 on the front of the button, greatly enhancing product recognition and brand display.

[0041] The light-blocking film 4 is made of black PET material with good light-blocking performance and has a thickness between 0.05-0.2mm, which can ensure good light-blocking effect without taking up too much internal space.

[0042] In the structural design of this solution, the light-shielding film 4 and the light guide plate 3 are designed in tandem to effectively improve the display performance of the logo on the front of the button, making the logo display clearer and more eye-catching.

[0043] In this embodiment, the light-shielding film 4, light guide plate 3, and PCB board 2 within the cavity 12 are fixed with epoxy adhesive. Epoxy adhesive has excellent insulation properties, effectively avoiding the risk of short circuits in the internal circuitry and ensuring stable button operation. In addition, epoxy adhesive has good weather resistance, maintaining stable performance under different temperature and humidity conditions, and can play a certain role in waterproofing and dustproofing, improving the button's environmental adaptability and reliability.

[0044] In summary, the touch button provided in this application has a compact internal structure and high space utilization. Its internal component layout and waist-shaped design are more suitable for installation on heat sink panels with limited space, meeting the miniaturization and integration requirements of heat sinks and other equipment.

[0045] The button body provided in this application has a waist-shaped cavity with symmetrical buckles on the sides, which can achieve smooth guidance and self-positioning. The cavity can be precisely adapted to the contour hole, and installation can be completed by gently pushing in a specific direction, which improves assembly efficiency. In addition, the waist-shaped design has a foolproof function to ensure that the logo is in the correct direction during installation.

[0046] The internal light-shielding film and light guide plate design provided in this application effectively improve the luminous indication performance of the button, making the light clearer and more uniform; at the same time, the touch-sensitive design avoids wear and tear on mechanical parts, greatly improving the button's service life and reliability.
