[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0025] Reference Figures 1-6

[0026] The switch body 1 of the automobile seat heating control switch is a core component that integrates multiple key components to achieve precise control of the seat heating function. It serves as a precise command center that coordinates the work of various parts to ensure the stable and reliable operation of the seat heating system.

[0027] The key 3 is the interface for users to directly interact with the seat heating controller, designed with ergonomics for easy pressing or releasing. When users perform these operations, it is like issuing clear instructions to the controller, triggering the corresponding control process to turn on, adjust, or turn off the seat heating function.

[0028] The action of the key 3 is not just a simple mechanical movement, but also closely connected with other components, triggering a series of chain reactions. When the key 3 is pressed down by external force, it will drive the subsequent components to work together to turn on the circuit and power on the seat heating device.

[0029] The contact 8 plays a crucial role in the circuit conduction. When the key 3 is pressed down by external force, it will accurately press the contact 8 to adhere to the gold layer on the PCB 9. This adhesion action is like opening the "switch" of the circuit, allowing the current to flow smoothly, realizing the connection of the circuit, and thus controlling the power-on of the seat heating device.

[0030] After the external force disappears, it can quickly reset, which is the key to ensuring the repeatability and stability of the controller's operation. After resetting, the controller can continue to work and accurately display the current gear state, providing continuous feedback to the user. This allows users to know the heating status of the seat at any time, whether during vehicle startup or driving, ensuring the stable operation of the seat heating function.

[0031] The PCB 9 is the core circuit carrier of the controller, carefully arranged with 2 gear signal lamp beads (red light source), a backlight lamp bead (white light source), and 2 gold contact rings. These lamp beads are not just simple light-emitting elements, but have multiple important functions. The backlight lamp bead turns on at the same time when the vehicle is powered on, providing clear visual feedback to the user. Even in a relatively dark environment, users can easily find the location of the seat heating controller and understand whether it is in the power-on state. The gear signal lamp bead displays different colors according to different working states, allowing users to intuitively understand the current gear of the seat heating, and thus adjust it according to their needs.

[0032] In addition to the lamp beads, the PCB board 9 also carries complex circuits responsible for distributing electrical current to various components and enabling signal transmission and processing. It connects with the vehicle's electrical system through the connector 10, ensuring that the controller can receive power supply from the vehicle and transmit control signals to the seat heating device. In this process, the PCB board 9 acts as a bridge, closely linking the vehicle's power supply and control signals with the seat heating device, enabling the entire system to work in harmony.

[0033] The connector 10 is used to connect the controller with the external wiring harness, and is the key link for signal and power transmission. It serves as a link that tightly connects the PCB board 9 with the vehicle's electrical system. During vehicle operation, the connector 10 can stably transmit electrical current and control signals, ensuring that the seat heating controller can normally receive power supply from the vehicle and accurately transmit user's operation instructions to the seat heating device, achieving precise control of the seat heating function.

[0034] The light guide block 2 is installed on the key 3 and is responsible for transmitting the light of the corresponding gear indicator light to the surface of the key 3. It serves as a light guide, accurately transmitting the light emitted by the gear signal lamp beads on the PCB board 9 to the surface of the key 3, allowing users to clearly see the gear status of the seat heating.

[0035] The connection between the light guide block 2 and the key 3 is achieved through the first buckle 12 and the first card slot. This connection method has many advantages. First, it ensures the stable installation of the light guide block 2, which can be firmly fixed on the key 3 during vehicle driving, even under vibration and jolt, and will not easily loosen or fall off, ensuring the stability of light transmission. Second, this buckle connection method is easy to disassemble and replace, which can quickly and conveniently install the light guide block 2 on the key 3 during production, improving production efficiency; and when repairing, if the light guide block 2 is damaged or fails, maintenance personnel can easily disassemble and replace it, reducing maintenance cost and difficulty.

[0036] The mounting ring 4 is located below the key 3 and is connected with the key 3 through the second buckle 13 and the second card slot. This connection method not only ensures the close combination between the mounting ring 4 and the key 3, but also makes them form a whole in structure and work together.

[0037] The installation ring 4 can play multiple important roles. First, it can fix the position of the button 3, ensuring that the button 3 does not shift or wobble during operation, improving the accuracy and stability of the button 3 operation. Second, the installation ring 4 can have the function of enhancing the stability of the button 3, through reasonable structural design, it can share the external force received by the button 3, reduce the possibility of deformation or damage of the button 3 due to long-term use. In addition, the installation ring 4 can also provide a certain sealing effect to prevent dust, moisture and other impurities from entering the inside of the button 3. In the use environment of the vehicle, dust and moisture are common pollutants, which may affect the normal operation of the button 3, even cause circuit short circuit and other faults. The sealing effect of the installation ring 4 can effectively block these impurities, protect the electronic components inside the button 3, prolong the service life of the button 3, and ensure the reliability and stability of the seat heating controller.

[0038] The rubber pad 5 is located between the installation ring 4 and the button 3 slider 6, which is in a key position of the button 3 structure. When the user presses the button 3, the rubber pad 5 can absorb part of the impact force. During the operation of the button 3, the external force applied by the user will be transmitted to the rubber pad 5 through the button 3, and the rubber pad 5 can convert this part of the impact force into elastic deformation by virtue of its own elastic properties, thereby reducing the collision and wear between the button 3 and other components. At the same time, the rubber pad 5 can also reduce the noise generated during the operation of the button 3, providing users with a more quiet and comfortable use experience. In the quiet driving environment of the vehicle, reducing unnecessary noise is crucial to improving user satisfaction, and the shock-absorbing and noise-reducing function of the rubber pad 5 meets this demand well.

[0039] The button 3 slider 6 is a circularly designed component, which has certain advantages. The circular periphery is uniformly stressed, and when cooperating with the structure inside the shell 7, it can realize smoother sliding, reducing the possibility of friction resistance and jamming. The button 3 slider 6 is internally provided with three cavities, which correspond to the light sources of three lamp beads respectively, and they play a key role in light transmission and button 3 operation.

[0040] The button 3 slider 6 is placed inside the shell 7, and the slide grooves on its two sides are in contact with the 2 sets of protruding tracks inside the shell 7. This track and slide groove cooperation structure realizes the directional reciprocating sliding of the button 3 slider 6. During the operation of the button 3, the button 3 slider 6 can slide accurately along the track without deviating from the track or wobbling, ensuring the accuracy and stability of the button 3 operation.

[0041] The shell 7 serves as the outer shell of the entire switch body 1, and is an important barrier for protecting the internal components. The shell 7 not only has a protective effect, but also provides a mounting and supporting structure for the key 3 slider 6, rubber pad 5, mounting ring 4 and other components. Its internal design is matched with the shapes and sizes of various components, so that these components can be accurately mounted inside the shell 7 and maintain a relatively stable position. Through reasonable structural layout, the shell 7 can ensure the structural stability and sealing of the entire switch body 1, and ensure smooth cooperation between various components.

[0042] The connector cover 11 is arranged outside the connector 10, and its main function is to protect the connector 10 from the external environment. It can effectively block the entry of external impurities, ensure the cleanliness and dryness of the connector 10, and ensure the reliability of signal and power transmission.

[0043] In use of the utility model, after the vehicle is ignited and powered on, the current is transmitted to the PCB board 9 through the connector 10. At this time, the backlight lamp beads (white light source) on the PCB board 9 are lit at the same time, providing backlight illumination for the key 3, so that the user can clearly see the position and state of the seat heating controller. At the same time, the gear signal lamp beads (red light source) on the PCB board 9 are in standby state, ready to display according to the actual working state of the seat heating. When the user presses the key 3, the key 3 is forced to move downward, driving the key 3 slider 6 to move downward along the inside of the shell 7. In this process, the contact 8 below the key 3 slider 6 also moves downward, and when the conductive silicone contact below the contact 8 contacts the gold contact ring on the PCB board 9, the switch is turned on, the circuit is connected, and the seat heating device starts to work.

[0044] The light guide block 2 conducts the light of the gear signal lamp beads to the surface of the key 3, so that the user can intuitively see the gear state of the seat heating. At the same time, the laser-engraved seat heating LOGO on the surface of the key 3 will also light up due to the light conduction of the backlight lamp beads, increasing the beauty and recognition of the product.

[0045] When the user releases the key 3, the external force disappears, the contact 8 rebounds by its own elasticity, driving the key 3 slider 6 and the key 3 to return to the initial position, and the switch resets.

[0046] At this time, the controller continues to work and displays the corresponding gear state according to the current running state of the seat heating device, waiting for the next operation of the user. Various components work together to realize efficient and stable operation of the automobile seat heating control switch, and provide users with comfortable and convenient seat heating control experience.

[0047] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
