Description

Technical Field

[0001] This utility model relates to the technical field of automotive lighting, and in particular to a snap-on type automotive LED headlight that is easy to install. Background Technology

[0002] In the automotive lighting field, LED headlights are gradually becoming the mainstream choice due to their advantages such as high brightness, low energy consumption, and long lifespan. However, existing automotive LED headlights still have significant shortcomings in terms of installation methods and heat dissipation performance. Traditional headlight connection methods are usually cumbersome, requiring specialized tools or trips to auto repair shops for assembly, which not only increases user costs but also reduces installation efficiency. Furthermore, some automotive LED headlights, due to their high power, generate a large amount of heat during operation. If heat dissipation is not timely, the internal temperature of the headlight will rise, affecting its lifespan and performance stability. While some heat dissipation designs exist in existing technologies, they are often structurally complex and struggle to simultaneously meet the requirements of efficient heat dissipation and convenient installation. Therefore, developing an automotive LED headlight that can achieve both rapid installation and effective heat dissipation has become a pressing technical challenge. Utility Model Content

[0003] The purpose of this invention is to provide a snap-on type automotive LED headlight that is easy to install, in order to overcome the shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-install snap-on automotive LED headlight includes a plug base, a light-emitting component, a heat dissipation system, and an electrical connection design, wherein: The plug base is a cylindrical structure with its bottom extending to the middle to form a plane. A top block is provided on this plane, and the top block cooperates with the plug base through a radial moving mechanism. When the plug base is rotated and inserted into the car mounting part, the top block moves radially outward and engages with the corresponding slot in the car mounting part, thus fixing the lamp.

[0005] Furthermore, the light-emitting component includes a left lamp body and a right lamp body, which are fixedly connected by multiple screws to form an internal accommodating chamber. A stepless adapter plate, a driver plate, and a copper plate assembly for LED beads are sequentially arranged within the accommodating chamber. These components are fixed to the inner wall of the accommodating chamber by screws or clips. The copper plate assembly for LED beads is located in the middle of the left and right lamp bodies and scatters light through a light-transmitting part. The light-transmitting part is made of a high-transmittance optical material, and its surface is treated with an anti-glare coating to improve the uniformity and safety of the light.

[0006] Specifically, the heat dissipation system includes a fan and a fan adapter plate, with the fan electrically connected to the driver board via the adapter plate. The fan is mounted near the top of the left and right lamp bodies, with its air inlet communicating with the outside air and its outlet pointing towards the heat dissipation area of ​​the LED copper plate assembly. The fan adapter plate is fixed to the inner wall of the left and right lamp bodies with screws and electrically connected to the driver board via wires. When the fan is running, airflow enters through the air inlet and is blown towards the LED copper plate assembly through the air outlet, thereby carrying away heat and preventing heat accumulation.

[0007] Furthermore, the electrical connection design includes the electrical connections between the stepless adapter board, the driver board, the LED copper plate assembly, and the fan. The stepless adapter board makes contact with the positive and negative terminals of the plug base via metal spring contacts to achieve power input. The stepless adapter board is connected to the driver board via wires, and the driver board further supplies power to the LED copper plate assembly and the fan via wires. The aforementioned wires are wrapped with heat-shrink tubing to ensure the insulation and stability of the electrical connection.

[0008] The modular design is reflected in the connection methods between the components. The left and right lamp bodies are fixedly connected by screws, forming a compact housing chamber. The stepless adapter plate, driver plate, and lamp bead copper plate assembly are all fixed to the inner wall of the housing chamber by screws or clips, facilitating assembly and maintenance. The fan is connected to the driver plate through a fan adapter plate, which is fixed to the inner wall of the left and right lamp bodies by screws, ensuring the stability and reliability of the fan.

[0009] Furthermore, the specific implementation of the snap-fit ​​connector structure is as follows: the top block is connected to the planar portion of the plug base via a spring mechanism. The elastic force of the spring mechanism keeps the top block in a contracted state when not subjected to external force. When the plug base is rotated into the automotive mounting part, the top block is squeezed by the inner wall of the automotive mounting part and moves radially inward, compressing the spring mechanism. When the plug base is rotated into place, the top block loses its compression and moves radially outward under the action of the elastic force of the spring mechanism, finally snapping into the slot of the automotive mounting part, thus completing the fixing of the lamp.

[0010] Specifically, the arrangement of the LED bead copper plate assembly is as follows: the LED bead copper plate assembly contacts the inner walls of the left and right lamp bodies via thermally conductive silicone pads. The thickness of the thermally conductive silicone pads is 1mm to 2mm, used to fill the gap between the LED bead copper plate assembly and the inner wall of the lamp body, improving heat conduction efficiency. Multiple LED beads are welded to the surface of the LED bead copper plate assembly, and the LED beads are arranged in a matrix to ensure uniform light distribution.

[0011] Furthermore, the fan's operation control method is as follows: the driver board has a built-in temperature sensor that monitors the temperature of the LED copper plate assembly in real time. When the temperature sensor detects that the temperature of the LED copper plate assembly exceeds a preset threshold, the driver board sends a start signal to the fan, and the fan starts running. When the temperature sensor detects that the temperature of the LED copper plate assembly is lower than the preset threshold, the driver board sends a stop signal to the fan, and the fan stops running. The temperature sensor is fixed to the driver board by soldering and is electrically connected to the driver board via wires.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The snap-fit ​​connection simplifies the installation process, allowing users to install and remove the lights without specialized tools. A built-in fan and optimized heat dissipation design effectively dissipate heat generated during operation, preventing heat buildup and significantly extending the lifespan of the lights. The modular design ensures a rational layout of components, resulting in a compact and easy-to-maintain overall structure. Optimized electrical connections guarantee stable power transmission, enhancing the reliability of the lights.

[0013] Specifically, this invention achieves rapid installation and disassembly of the lamp through the cooperation of the top block and spring mechanism, while ensuring that the lamp will not loosen due to vibration during use. The synergistic effect of the thermally conductive silicone pad and the fan improves the lamp's heat dissipation efficiency and extends its service life. The modular design ensures simple and reliable connections between components, facilitating assembly and maintenance, and reducing production costs and maintenance difficulty.

[0014] Furthermore, this invention achieves stable power input by ensuring contact between the positive and negative terminals of the stepless adapter plate and the plug base. The stepless adapter plate is connected to the drive board via wires, and the drive board further supplies power to the lamp bead copper plate assembly and the fan via wires, ensuring the normal operation of the lamp. The above electrical connection design improves the insulation and reliability of the electrical connection by wrapping the wires with heat shrink tubing.

[0015] In summary, this utility model, through its innovative structural design and efficient heat dissipation system, solves the problems of complex installation and insufficient heat dissipation in existing technologies, providing users with a convenient and reliable automotive LED headlight solution.

[0018] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings: like Figure 1-3 As shown in the figure, this embodiment provides a specific implementation of a snap-on automotive LED headlight that is easy to install. The headlight includes a plug base 1, a left lamp body 2, a right lamp body 3, a fan 4, a fan adapter plate 5, a lamp bead copper plate assembly 6, a stepless adapter plate 7, a driver board 8, screws 9, and a top block 10. These components, through reasonable structural design and electrical connections, achieve rapid installation, efficient heat dissipation, and stable operation of the lamp.

[0019] The plug base 1 is a cylindrical structure with a flat surface extending from its bottom to the middle, where a top block 10 is located. The top block 10 engages with the plug base 1 via a spring mechanism. When the plug base 1 is rotated into the automotive mounting part, the top block 10 moves radially outward and engages with the corresponding slot in the automotive mounting part. The top block 10 is made of an elastic material, ensuring it remains in a contracted state when not under external force, while being able to move radially when compressed. After the plug base 1 is rotated into place, the top block 10 releases the compression and moves radially outward under the elastic force of the spring mechanism, ultimately securing the lamp. This snap-fit ​​connection structure simplifies the lamp installation process, allowing users to install and remove the lamp without the need for specialized tools.

[0020] The light-emitting component consists of a left lamp body 2 and a right lamp body 3, which are fixedly connected by multiple screws 9 to form an internal accommodating chamber. A stepless adapter plate 7, a driver plate 8, and an LED bead copper plate assembly 6 are arranged sequentially within the accommodating chamber. These components are fixed to the inner wall of the accommodating chamber by screws or clips to ensure the stability of each component. The LED bead copper plate assembly 6 is located in the middle of the left lamp body 2 and the right lamp body 3, and scatters light through a light-transmitting part. The light-transmitting part is made of a high-transmittance optical material, and its surface is treated with anti-glare to improve the uniformity and safety of the light. Multiple LED beads are welded to the surface of the LED bead copper plate assembly 6 in a matrix arrangement to ensure uniform light distribution.

[0021] The heat dissipation system includes a fan 4 and a fan adapter plate 5. The fan 4 is electrically connected to the driver board 8 via the fan adapter plate 5. The fan 4 is installed near the top of the left lamp body 2 and the right lamp body 3. The air inlet of the fan 4 is open to the outside air, while the air outlet points towards the heat dissipation area of ​​the LED copper plate assembly 6. When the fan 4 is running, airflow enters through the air inlet and blows onto the LED copper plate assembly 6 through the air outlet, thereby carrying away heat and preventing heat accumulation. The operation control method of the fan 4 is as follows: the driver board 8 has a built-in temperature sensor that monitors the temperature of the LED copper plate assembly 6 in real time. When the temperature sensor detects that the temperature of the LED copper plate assembly 6 exceeds a preset threshold, the driver board 8 sends a start signal to the fan 4, and the fan 4 starts running. When the temperature sensor detects that the temperature of the LED copper plate assembly 6 is lower than the preset threshold, the driver board 8 sends a stop signal to the fan 4, and the fan 4 stops running. The temperature sensor is fixed to the driver board 8 by soldering and is electrically connected to the driver board 8 via wires.

[0022] The electrical connection design includes the electrical connections between the stepless adapter board 7, the driver board 8, the LED copper plate assembly 6, and the fan 4. The stepless adapter board 7 connects to the positive and negative terminals of the plug base 1 via metal spring contacts, enabling power input. The stepless adapter board 7 is connected to the driver board 8 via wires, and the driver board 8 further supplies power to the LED copper plate assembly 6 and the fan 4 via wires. These wires are wrapped with heat-shrink tubing to ensure the insulation and stability of the electrical connection. The design of the stepless adapter board 7 makes power transmission more stable and reduces the risk of failure due to poor contact.

[0023] The modular design is reflected in the connection methods between the components. The left lamp body 2 and the right lamp body 3 are fixedly connected by screws 9, forming a compact housing chamber. The stepless adapter plate 7, the drive plate 8, and the lamp bead copper plate assembly 6 are all fixed to the inner wall of the housing chamber by screws or clips, facilitating assembly and maintenance. The fan 4 is connected to the drive plate 8 through a fan adapter plate 5, which is fixed to the inner wall of the left lamp body 2 and the right lamp body 3 by screws, ensuring the stability and reliability of the fan 4. The modular design not only improves assembly efficiency but also reduces production costs and maintenance difficulty.

[0024] The arrangement of the LED bead copper plate assembly 6 is as follows: the LED bead copper plate assembly 6 contacts the inner walls of the left lamp body 2 and the right lamp body 3 through thermally conductive silicone pads. The thickness of the thermally conductive silicone pads is 1mm to 2mm, used to fill the gap between the LED bead copper plate assembly 6 and the inner wall of the lamp body, improving heat conduction efficiency. Multiple LED beads are welded to the surface of the LED bead copper plate assembly 6, and the LED beads are arranged in a matrix to ensure uniform light distribution. The selection of the thermally conductive silicone pads takes into account their thermal conductivity and flexibility, enabling them to accommodate certain assembly errors while ensuring good heat conduction.

[0025] The operating principle of this utility model is as follows: S1 The plug base 1 is inserted into the car mounting part and rotated. The top block 10 moves radially and snaps into the slot of the car mounting part, completing the fixation of the lamp; S2 The stepless adapter plate 7 contacts the positive and negative terminals of the plug base 1 through metal springs to realize power input; S3 The stepless adapter plate 7 transmits power to the drive board 8 through wires. The drive board 8 further supplies power to the lamp bead copper plate assembly 6 and the fan 4 through wires respectively; S4 The LED beads on the lamp bead copper plate assembly 6 are lit, emitting uniform light; S5 The temperature sensor built into the drive board 8 monitors the temperature of the lamp bead copper plate assembly 6 in real time. When the temperature exceeds the preset threshold, the drive board 8 sends a start signal to the fan 4, and the fan 4 starts running to remove heat; S6 When the temperature is lower than the preset threshold, the drive board 8 sends a stop signal to the fan 4, and the fan 4 stops running. The above steps ensure that the lamp can achieve rapid installation, efficient heat dissipation and stable operation during use.

[0026] The practical applications of this utility model include, but are not limited to, automotive headlights, taillights, and fog lights. In actual use, users only need to insert the plug base 1 into the car's mounting part and rotate it to complete the installation of the lamp. When the lamp is working, the LED beads on the lamp bead copper plate assembly 6 are lit, emitting uniform light. At the same time, the fan 4 automatically starts and stops based on feedback from the temperature sensor to ensure the lamp's heat dissipation effect. The modular design makes the layout of each component reasonable, the overall structure compact and easy to maintain, significantly improving the user experience.

[0027] In summary, this utility model, through its innovative structural design and efficient heat dissipation system, solves the problems of complex installation and insufficient heat dissipation in existing technologies, providing users with a convenient and reliable automotive LED headlight solution.

[0028] The technical features of the above embodiments can be combined arbitrarily.

However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification. For those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
