[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.
[0021] Please see Figure 1-6 This utility model provides a technical solution: a multi-layer lamp cover structure for automotive LED headlights, including a housing 1, a snap-fit seat 2 fixedly installed on the upper outer side of the housing 1, an inner lamp cover 5 fixedly installed on the upper end of the housing 1, and the snap-fit seat 2 located on the outer side of the inner lamp cover 5, a mounting component 3 provided directly above the snap-fit seat 2, an outer lamp cover 4 fixedly installed on the upper end of the mounting component 3, a snap-fit mechanism provided between the snap-fit seat 2 and the mounting component 3, and a heat dissipation mechanism provided in the middle of the outer side of the housing 1.
[0022] In this embodiment, a snap-fit seat 2 is provided at the upper end of the outer casing 1, and an mounting component 3 is provided directly above the snap-fit seat 2. An outer lamp cover 4 is fixedly installed on the outer side of the upper end of the mounting component 3. At the same time, a snap-fit mechanism is provided between the snap-fit seat 2 and the mounting component 3. Under the action of the snap-fit mechanism, the mounting component 3 can be snapped onto the upper end of the snap-fit seat 2 in a convenient and quick manner, and it is also easy to disassemble. Thus, the outer lamp cover 4 is fitted on the outside of the inner lamp cover 5, and the outer lamp cover 4 provides protection for the inner lamp cover 5. Through the setting of multiple lamp covers, the protection performance of the automotive LED headlights is increased.
[0023] Specifically, the snap-fit mechanism includes an annular insertion groove 21 formed on the bottom inner side of the snap-fit base 2. Limiting grooves 24 are formed on both sides of the snap-fit base 2, and the limiting grooves 24 are located above and to the side of the annular insertion groove 21. An annular insertion block 32 is fixedly installed at the lower end of the mounting component 3. The annular insertion block 32 corresponds to and fits the annular insertion groove 21. Limiting blocks 31 are movably provided on both outer surfaces of the mounting component 3. The limiting blocks 31 correspond to and fit the limiting grooves 24. Inner cavities 33 are formed on both sides of the mounting component 3. One end of the limiting block 31 is movably inserted into the inner cavity 33. A movable block 332 is fixedly installed at the end of the limiting block 31 located inside the inner cavity 33. The movable block 332 is movably disposed inside the inner cavity 33. Several springs 331 are disposed inside the inner cavity 33. The two ends of the springs 331 are fixedly connected to the movable block 332 and the inner wall of the inner cavity 33, respectively. The lower side of the end of the limiting block 31 located outside the inner cavity 33 is provided with an inclined surface 211. The inner side of the upper frame of the snap-fit seat 2 is provided with an inclined surface 23. Both the inclined surface 23 and the inclined surface 311 are at a 45-degree angle to the horizontal. The lower end of the annular insertion block 32 is fitted with an annular magnet 321. The bottom of the annular insertion groove 21 is fitted with an annular magnet 22. The positions of the annular magnet 321 and the annular magnet 22 are corresponding and compatible.
[0024] In this embodiment, a snap-fit mechanism is provided between the snap-fit base 2 and the mounting component 3. Under the action of the snap-fit mechanism, when the outer lampshade 4 needs to be fitted onto the outside of the inner lampshade 5, the mounting component 3 and the outer lampshade 4 are first placed above the snap-fit base 2. Then, the annular insertion block 32 provided at the lower end of the mounting component 3 is first inserted into the inner side of the annular insertion groove 21. When the annular insertion block 32 is gradually inserted into the inside of the annular insertion groove 21, the limiting blocks 31 movably provided on both sides of the mounting component 3 begin to contact the snap-fit base 2. One end of the limiting block 31 and the inner side of the upper frame of the snap-fit base 2 are respectively provided with an inclined surface 211 and an inclined surface 23. The inclined surface 211 and the inclined surface 23 are both at a 45-degree angle to the horizontal. When the two are in contact, the limiting block 31 moves inward. When the limiting block 31 reaches the position of the limiting groove 24, Under the action of the spring 331 set inside the inner cavity 33, the limiting block 31 will be locked inside the limiting groove 24, thus completing the locking. At this time, the lower end of the annular plug 32 contacts the bottom of the annular plug groove 21. The annular magnet 321 set at the lower end of the annular plug 32 and the annular magnet 22 embedded at the bottom of the annular plug groove 21 can attract each other, which can further increase the stability of the locking seat 2 and the mounting part 3 when locking. At the same time, the lower end of the mounting part 3 is fixedly installed with the annular plug 32. The position of the annular plug 32 corresponds to and matches the annular plug groove 21. The annular plug 32 is inserted into the annular plug groove 21, and the two form a sealing relationship to achieve waterproofing. Meanwhile, the inner lamp cover 5 is directly fixedly installed on the outer shell 1 to further achieve the purpose of waterproofing.
[0025] Specifically, the inner lampshade 5 is a transparent optical plastic component, the outer lampshade 4 is a high-strength polycarbonate component, and the outer surface of the outer lampshade 4 is provided with a nano-coating.
[0026] In this embodiment, the outer lampshade 4 is a high-strength polycarbonate component, and a nano-coating is provided on the outer side of the outer lampshade 4. The nano-coating has good wear resistance, impact resistance and self-cleaning properties, which can effectively resist damage to the lampshade from external factors such as stone impact and wind and sand erosion. At the same time, the self-cleaning properties of the nano-coating can make it easier to remove dirt such as dust and water stains on the surface of the lampshade, and maintain the light transmittance of the lampshade.
[0027] Specifically, the heat dissipation mechanism includes an air inlet 11 and an air outlet 12 located at the middle of both sides of the outer casing 1, and the air inlet 11 and the air outlet 12 are symmetrically distributed. A cooling fan 13 is installed inside the air inlet 11.
[0028] In this embodiment, by setting heat dissipation mechanisms on both sides of the middle position of the outer casing 1, a large amount of heat will be generated when the LED light inside the outer casing 1 works for a long time under the action of the heat dissipation mechanism. The setting of the air inlet 11, the air outlet 12 and the heat dissipation fan 13 can achieve efficient heat dissipation, ensure the stable operation of the LED light source, extend the service life of the LED light source and reduce maintenance costs.
[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
