Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to a waterproof automotive fog light with adjustable light output height. Background Technology

[0002] Car fog lights are auxiliary lighting devices installed at the front and rear of a car, specifically designed for low-visibility weather conditions such as fog, rain, and snow. Their core function is to enhance road lighting effects through a highly penetrating light source, helping drivers clearly identify road conditions and obstacles ahead, while also improving the vehicle's own road visibility, reducing driving safety hazards in adverse weather conditions, and ensuring the vehicle's visual warning and lighting needs during driving.

[0003] Existing automotive fog lights suffer from the drawback of not being able to adjust the beam height, resulting in a fixed beam angle. This fails to provide optimal illumination for different road conditions and driving needs, easily leading to blind spots or glare that can interfere with other road users. Even though some fog lights have added beam height adjustment components, these components are usually located at the rear of the fog light and need to extend into the lamp housing. This structural design easily compromises the lamp's seal, allowing moisture to seep into the lamp housing, causing short circuits, light source failure, fogging of the outer casing, and other malfunctions, severely affecting the fog light's waterproof performance and lifespan.

[0004] Therefore, this application urgently requires the design of a waterproof automotive fog light with adjustable beam height. This fog light should be able to flexibly adjust its beam height according to actual road conditions and driving needs to achieve optimal illumination, effectively eliminate blind spots, avoid glare interference, and improve driving safety in adverse weather conditions.

[0023] Existing automotive fog lights suffer from the drawback of not being able to adjust the beam height, resulting in a fixed beam angle. This fails to provide optimal illumination for different road conditions and driving needs, easily leading to blind spots or glare that can interfere with other road users. Even though some fog lights have added beam height adjustment components, these components are usually located at the rear of the fog light and need to extend into the lamp housing. This structural design easily compromises the lamp's seal, allowing moisture to seep into the lamp housing, causing short circuits, light source failure, fogging of the outer casing, and other malfunctions, severely affecting the fog light's waterproof performance and lifespan.

[0024] To address the aforementioned issues, this application provides a waterproof automotive fog light with adjustable light emission height. This allows for flexible adjustment of the fog light's light emission height based on actual road conditions and driving needs, achieving optimal illumination, effectively eliminating blind spots, preventing glare interference, and improving driving safety in adverse weather conditions. Simultaneously, it effectively maintains the lamp's sealing integrity, preventing moisture infiltration and subsequent malfunctions, effectively extending the fog light's lifespan, and further enhancing its practicality and reliability.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings. Example

[0026] Please see Figures 1-7The waterproof automotive fog light with adjustable light emission height disclosed in this application includes a light source assembly 1, a lamp housing 2, a mounting bracket 3, a pivot shaft 4, and a light emission height adjustment component 5. The light source assembly 1 is disposed within the lamp housing 2 and is used to emit illumination light, providing auxiliary lighting for the vehicle in inclement weather. The lamp housing 2 is waterproof, effectively preventing moisture ingress and protecting the internal light source assembly 1 from damage. The mounting bracket 3 is fitted onto the lamp housing 2 and is used to fix the fog light to the vehicle body, ensuring the stability and reliability of the entire fog light installation. The pivot shaft 4 is symmetrically arranged on both sides of the lamp housing 2, with one end abutting against the lamp housing 2 and the other end passing through the mounting bracket 3, allowing the lamp housing 2 to rotate at a certain angle relative to the mounting bracket 3 around the pivot shaft 4, providing a basis for subsequent light emission height adjustment. The light emission height adjustment component 5 is disposed on the lamp housing 2 and located at the rear end of the pivot shaft 4, and is used to adjust the light emission height.

[0027] Specifically, the lamp housing 2 includes an upper housing 23, a lower housing 24, and a fixing plate 25. The upper housing 23 and the lower housing 24 are fixedly connected by screws, and a receiving cavity is formed between the upper housing 23 and the lower housing 24. The receiving cavity is used to accommodate the light source assembly 1 and provide it with a safe and sealed installation environment. The front end of the lower housing 24 is provided with a light-transmitting opening 26, which communicates with the receiving cavity to ensure that the light emitted by the light source assembly 1 can be smoothly emitted to provide illumination for the vehicle. The fixing plate 25 is disposed in the receiving cavity and located between the upper housing 23 and the lower housing 24, and is used to fix and support the light source assembly 1 to ensure that the light source assembly 1 does not shake or shift within the lamp housing 2. Furthermore, in order to provide a relatively sealed environment for the light source assembly 1, the waterproof automotive fog light with adjustable light emission height also includes a face shield 6. The face shield 6 is disposed at the front end of the lamp housing 2 and covers the light-transmitting opening 26. The face shield 6 is made of a transparent waterproof material to prevent moisture and dust from entering the lamp, protect the light source assembly 1 from damage, and allow the light emitted by the light source assembly 1 to be smoothly emitted from the face shield 6.

[0028] The light emission height adjustment assembly 5 includes a screw 51 and a nut 52. The nut 52 is sleeved on the screw 51 and fixedly connected to the lamp housing 2. Specifically, to facilitate the installation of the light emission height adjustment assembly 5, the lamp housing 2 is also provided with a first slot 21 and a second slot 22. The first slot 21 and the second slot 22 are arranged sequentially from top to bottom on one side of the lamp housing 2. The first slot 21 is frame-shaped, and its size is adapted to the nut 52 to install and fix the nut 52. That is, the nut 52 is inserted into the first slot 21 and engaged with the first slot 21 to ensure that the nut 52 will not fall off or shift during adjustment. The second slot 22 is semi-circular and is used to limit the screw 51 to prevent the screw 51 from shaking during adjustment. More specifically, the screw 51 passes through the second slot 22 and the nut 52 sequentially from bottom to top, extends upward, and can move up and down relative to the nut 52.

[0029] Furthermore, to facilitate adjustment of the light emission height, the lower part of the screw 51 is also provided with a mounting sleeve 53, an elastic shaft plate 54, and a disc gear 55. The mounting sleeve 53 is fitted onto the lower end of the screw 51 and is fixedly connected to the screw 51. The top end of the elastic shaft plate 54 is set on the mounting sleeve 53 and is integrally formed with the mounting sleeve 53, while the bottom end extends outward, playing a buffering and shock-absorbing role, reducing the vibration and noise generated by the screw 51 during adjustment. The disc gear 55 is fitted onto the bottom end of the mounting sleeve 53 and is integrally formed with the mounting sleeve 53. When it is necessary to adjust the light emission height, simply rotate the disc gear 55 to drive the screw 51 to rotate, and the screw 51 will move up and down, thereby adjusting the center of gravity of the rear end of the lamp, so that the lamp housing 2 can use the fulcrum shaft 4 as a fulcrum and the lever principle to drive the front end of the lamp to move up and down in the opposite direction, thereby realizing the adjustment of the light emission height. It should be noted that the rotation of the disc gear 55 can be manually operated or driven by an external drive device to achieve automated adjustment of the light output height, thereby improving the convenience and accuracy of adjustment. In actual use, the driver can quickly adjust the fog light illumination angle by simple operation according to changes in road conditions, and obtain the best lighting effect in special road conditions such as curves and slopes.

[0030] The light source assembly 1 includes a light source 11, a light source mounting plate 12, a reflector 13, and a lens 14. Specifically, the light source 11 is mounted on the light source mounting plate 12, and the light emission direction of the light source 11 faces the reflector 13. The light source mounting plate 12 is disposed on and connected to the fixing plate 25 to ensure the stability and reliability of the installation of the light source 11. The reflector 13 covers the top and rear end of the light source 11 and is connected to the fixing plate 25, used to reflect and focus the light emitted by the light source 11, improving the utilization rate of light and the lighting effect. The lens 14 is disposed in front of the light outlet of the reflector 13 and adjacent to the light-transmitting opening 26, used to further refract and scatter the light, so that the light is more evenly illuminating the road and avoiding glare or blind spots.

[0031] Furthermore, to dissipate the heat emitted by the light source assembly 1 in a timely manner, the waterproof automotive fog light with adjustable light emission height also includes heat dissipation fins 7; several heat dissipation fins 7 are disposed on the lamp housing 2 and located at the rear end of the lamp housing 2 to increase the heat dissipation area and improve heat exchange efficiency, thereby enhancing heat dissipation efficiency. A heat dissipation gap is provided between two adjacent heat dissipation fins 7 to form a natural convection channel. Furthermore, to improve heat dissipation efficiency and construct a composite heat dissipation system combining active and passive heat dissipation, the waterproof automotive fog light with adjustable light emission height also includes a cooling fan 8; the cooling fan 8 is fixed on the heat dissipation fins 7 and connected to the heat dissipation gap, thereby accelerating airflow and quickly carrying away the heat generated inside the lamp, ensuring that the fog light maintains stable performance even under long-term operation, and effectively extending the service life of the light source assembly 1.

[0032] Working principle: Installation steps: First, install the light source 11 on the light source mounting plate 12, then fix the light source mounting plate 12 on the fixing plate 25. Place the reflector 13 over the light source 11 and at its rear end, connecting it to the fixing plate 25. Next, fix the lens 14 in front of the light outlet of the reflector 13 and near the light-transmitting opening 26. Then, insert the nut 52 into the first slot 21 on the lamp housing 2, securing it in place. Next, pass the screw 51 from bottom to top through the second slot 22 and the nut 52, completing the installation of the light-emitting height adjustment assembly 5. Finally, install the face shield 6 at the front end of the lamp housing 2, covering the light-transmitting opening 26 to provide a relatively sealed environment for the light source assembly 1. Finally, the mounting bracket 3 is securely fitted onto the lamp housing 2, and then the mounting bracket 3 is fixed to the vehicle body, thereby firmly fixing the entire fog light to the vehicle body and ensuring that the fog light will not shake or fall off during vehicle operation.

[0033] Light emission height adjustment and waterproof principle: After the lamp is installed, taking the light emission direction as parallel to the horizontal plane as an example, the center of gravity of the lamp is located in the middle of the lamp housing 2. When it is necessary to adjust the light emission height, rotate the disc gear 55 counterclockwise, so that the screw 51 rotates counterclockwise synchronously. At this time, since the nut 52 is fixed in the first slot 21 of the lamp housing 2, the screw 51 can move downward relative to the nut 52. In this process, the center of gravity of the rear end of the lamp will change, that is, the center of gravity of the rear end of the lamp will drop, so that the rear end of the lamp will move downward. According to the lever principle, and with the fulcrum shaft 4 as the fulcrum, when the center of gravity of the rear end of the lamp drops, the front end of the lamp will move upward, thereby adjusting the light emission direction upward; conversely, rotating the disc gear 55 clockwise raises the center of gravity of the rear end of the lamp, and the front end of the lamp will move downward, so that the light emission direction moves downward, thereby realizing flexible adjustment of the light emission height. In actual driving, when faced with different road conditions, such as curves and slopes, drivers can quickly adjust the fog light's beam angle according to actual needs, eliminating blind spots and preventing glare from interfering with other road users, effectively improving driving safety in adverse weather conditions. Moreover, whether manually rotating the disc gear 55 or automatically adjusting via an external drive device, the beam height can be precisely controlled to meet diverse driving scenario requirements. Furthermore, because the beam height adjustment component 5 is located on the lamp housing 2 and on its outer side, it does not require insertion into the lamp housing for operation, greatly maintaining the lamp's sealing integrity. This ensures that moisture does not seep into the lamp housing, preventing short circuits, light source 11 failure, and fogging caused by moisture, improving the overall waterproof performance of the fog light, extending its lifespan, and further enhancing its practicality and reliability.

[0034] In this embodiment, the waterproof automotive fog light with adjustable light emission height of this application includes a light source assembly, a lamp housing, a mounting bracket, a pivot shaft, and a light emission height adjustment assembly. By setting the pivot shaft, the lamp housing and the mounting bracket form a rotatable connection, providing a flexible rotational basis for adjusting the light emission height. By setting a screw, a nut, and a disc gear, and through their interaction, the user can easily and precisely control the screw to move up and down relative to the nut manually or electrically, thereby changing the center of gravity position of the lamp's rear end. This allows the lamp's front end to move up and down in the opposite direction, using the pivot shaft as a fulcrum and lever principle, achieving flexible and precise adjustment of the light emission height. This not only meets the lighting requirements under different road conditions and driving needs, effectively eliminates blind spots, avoids glare interference with other road users, but also greatly improves driving safety in adverse weather conditions. Meanwhile, by setting the light emission height adjustment component on the lamp housing and placing it on the outside of the lamp housing, it eliminates the need to extend into the lamp housing for operation. This greatly maintains the sealing integrity of the lamp, ensuring that moisture does not seep into the lamp housing. It avoids malfunctions such as short circuits, light source failure, and fogging of the outer casing caused by moisture, significantly improving the overall waterproof performance of the fog light, extending its service life, and further enhancing the practicality and reliability of the fog light.
