[0021] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] This utility model provides a charging touch switch structure with vibrant ambient lighting, integrating three main functions: charging, touch control, and ambient lighting. See also... Figure 1-2The structure mainly consists of three parts: the outer shell 100, the circuit board 200, and the base 300. The outer shell 100 integrates the panel, charging port, light guide, and decorative elements; the circuit board 200 adopts a functional separation and heat source partitioning design, separating the charging circuit and the touch circuit on different circuit boards, and also partitioning high-heat-generating components (such as inductors and power ICs) and low-heat-generating components (such as the main control MCU and sensor circuits); the base 300 mainly serves for structural fixation and protection. Its innovation lies in the integration of ambient lighting into the TYPE-C charging port 120, allowing the charging port to not only have high-power charging capabilities but also become part of the ambient lighting system.
[0023] Install the TYPE-C charging port 120 module with ambient lighting into the designated position on the panel component 110. Then, install multiple circuit boards designed according to the concept of "functional separation and heat source partitioning" and complete the electrical connection. Finally, install the aluminum alloy base 300 onto the panel, enclosing the entire circuit board component 200 within it, completing the structural encapsulation.
[0024] This device integrates high-power charging, touch switching, and ambient lighting into one unit, meeting the combined demands of modern automobiles, smart homes, and other scenarios for multifunctionality, aesthetics, and a high-tech feel. The circuit board's "functional separation and heat source partitioning" design physically isolates the high-frequency, high-current charging circuit from the high-sensitivity touch detection circuit, effectively preventing electromagnetic interference and significantly improving the accuracy of touch control and the overall system stability. High-heat-generating components are concentrated in the area in contact with the 300mm heat dissipation surface of the base, laying the foundation for efficient heat dissipation and solving the heat generation problem caused by high-power charging.
[0025] In one embodiment, the panel component 110 comprises, from the outside to the inside: a panel, a sensor bonded to the back of the panel by optical adhesive, a diffuser bonded to the back of the sensor, and a light-blocking cotton bonded to the back of the diffuser.
[0026] When assembling panel component 110, the capacitive touch sensor is first precisely attached to the touch sensing area on the inside of the panel using high-transmittance OCA optical adhesive. Then, a diffuser (such as a microstructured frosted PC sheet) is attached to the back of the sensor, and finally, black light-blocking cotton (such as black PET foam) is attached to the back of the diffuser.
[0027] Optical adhesive fills the air gap between the panel and the sensor, reducing light refraction and signal loss, making touch signals more sensitive. A diffuser disperses point or strip-shaped LED light sources, forming a uniform surface light source, eliminating "glare," and enhancing visual effects and a premium feel. Light-blocking material prevents internal light from leaking out of non-display areas, ensuring light only shines through the designed light guides or display areas, resulting in high contrast and a pure visual effect.
[0028] In one embodiment, the TYPE-C charging port 120 includes an 18W and a 60W charging port, both of which have built-in ambient lights and are integrated inside the housing.
[0029] Two adjacent mounting positions are reserved on the outer casing to embed 18W (suitable for fast charging of conventional devices such as mobile phones) and 60W (suitable for high-power devices such as laptops) TYPE-C charging female connector modules, respectively. Each female connector module is surrounded by surface-mount LEDs as ambient lighting.
[0030] It offers two different charging power options to meet the charging needs of various devices, from mobile phones to laptops, making it highly versatile. Each charging port has its own ambient light, allowing users to clearly identify the port's location. Changes in light color or mode can also indicate the charging status (such as standby, charging, fully charged, fault, etc.), providing a user-friendly interface. The integrated indicator light and charging port design saves internal space and simplifies the structure.
[0031] In one embodiment, the outer casing has a reflective layer on its surface or body.
[0032] The outer shell is directly injection molded from porcelain-white PC+ABS material, utilizing the material's inherent porcelain-white high-reflectivity to form a reflective layer. Another implementation involves coating the inner surface of a regular plastic shell with a highly reflective white or mirror-silver coating.
[0033] The reflective layer reflects the light emitted by the light guide and ambient light towards the panel as much as possible, reducing light absorption and loss within the housing. This results in higher and more uniform final light output, while also reducing the LED drive current and achieving energy savings. It also prevents dark areas or shadows from forming inside the housing due to light exposure, ensuring the purity and sophistication of the ambient lighting effect.
[0034] In one embodiment, the decorative frame and the outer shell are connected by a combination of mounting bracket snap-fit and thermal riveting.
[0035] During assembly, the clips on the decorative frame are first snapped into the four mounting brackets on the outer shell for initial positioning and pre-fixation. Then, a hot riveting head is used to heat and flatten the ten pre-drilled plastic posts on the decorative frame, melting them to form rivet heads that securely lock them to the outer shell. The snap-fit provides quick positioning and initial fixation, while the hot riveting provides permanent mechanical locking. The combination of these two methods ensures that the decorative frame will not loosen or produce abnormal noises even under vibration. This eliminates the need for screws and other metal fasteners, simplifying material management, reducing costs, and resulting in a cleaner, more aesthetically pleasing appearance without screw holes. The snap-fit and hot riveting process is suitable for automated production, making the assembly process simple and fast.
[0036] In one embodiment, the circuit board component 200 consists of four circuit boards, including two 4-layer boards and two double-sided boards.
[0037] The circuitry responsible for 60W high-power fast charging, complex wiring, and high interference resistance is designed on a 4-layer board; touch detection and LED driver circuitry are designed on two other double-sided boards. These are interconnected via board-to-board connectors or flexible circuit boards. The use of 4-layer and double-sided boards is differentiated based on circuit complexity and signal integrity requirements. Low-cost double-sided boards are used for simple circuits, while higher-performance 4-layer boards are used for complex, high-speed circuits, achieving an optimal balance between cost and performance. Using multiple small boards instead of a single large board naturally achieves an architectural design of "functional separation" and "heat source partitioning."
[0038] In one embodiment, the base 300 is in direct contact with the heat-generating components for heat dissipation.
[0039] An aluminum alloy base 300 is used. During assembly, thermal grease is applied to the top of the main heat-generating components (such as power inductors and MOSFETs) on the circuit board, and then the circuit board is mounted onto the base 300, ensuring that these components are in close contact with the inner wall of the aluminum alloy base 300 through the thermal grease.
[0040] The heat generated by the components is directly conducted to the metal base 300. The base 300 acts as a large heat sink, dissipating the heat into the surrounding air through natural convection and radiation, significantly reducing the operating temperature of high-power components. This effectively controls the temperature rise of core components, preventing performance degradation or damage caused by overheating, and greatly improving the long-term reliability and service life of the product.
[0041] In one embodiment, the specific functional application of the switch structure is to control the refrigerator's locking / unlocking, the second-row screen switch, the second-row seat heating, the second-row seat ventilation, and the refrigerator's cooling and heating functions.
[0042] In the firmware of the touch function circuit board, different touch button areas are defined and mapped to the four functions mentioned above. After the user touches the corresponding area, the main control MCU will send instructions to the corresponding control unit of the vehicle (such as the seat ECU or the entertainment system host) via the CAN bus to execute the corresponding operation.
[0043] Integrating multiple disparate control functions within a single area onto a visually advanced panel simplifies automotive interior design and optimizes the user experience. It also clarifies the control panel's suitability for the second-row seating area, identifying specific and advantageous application scenarios and enhancing its practicality for the industry.
[0044] In one embodiment, the ambient light is located around the TYPE-C charging port 120, and the light emitted from it is guided to the panel component 110 through a light guide column, thereby creating a dazzling ambient effect.
[0045] Multi-colored LEDs (such as RGB LEDs) are used as ambient lighting and arranged around the charging port module. Specific light guide pillars are designed with their light-incident ends aligned with these LEDs. Through total internal reflection within the pillars and the microstructure design of the surface, the light is conducted and evenly projected onto the sides of the panel or specific light-transmitting areas.
[0046] Transforming the charging port, a practical functional area, into a soft light source achieves a perfect combination of function and aesthetics, creating a cool, technological atmosphere. Precise control of the light path through light guide columns ensures that the light reaches the intended display area, avoiding stray light and resulting in clean, crisp lighting effects.
[0047] In one embodiment, the light guide column is installed inside the housing and located between the ambient light and the panel component 110, and its core function is to evenly disperse the light.
[0048] The light guide column is usually made of high-transmittance PMMA or PC material and is fixed inside the housing by a slot. The side facing the LED is designed as the light-incident surface, while the side facing the panel is designed with various dots, V-grooves or frosted textures as the light-outceasing surface. These structures break total internal reflection and "squeeze" the light out evenly.
[0049] This is a key component for eliminating "point-like" light sources. It can transform the intense light from a few LEDs into uniform, soft, flat light without bright or dark stripes, greatly improving the visual effect and product texture. As a bridge connecting the light source and the display interface, it tightly integrates the lighting system inside the housing, resulting in a compact structure and high reliability.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
