Description

Technical Field

[0001] This utility model relates to the field of automotive headlight protection, specifically an anti-scattering light shield for automotive headlights. Background Technology

[0002] Car headlight visors are components installed in front of or behind car headlights. Their main function is to block part of the light, ensuring that the light emitted by the headlights has a reasonable direction and range of illumination, avoiding glare caused by light scattering, and improving driving safety at night or in bad weather. They are made of light-blocking materials, which can effectively control the angle of light scattering, making the light more concentrated, illuminating the road ahead while reducing interference to oncoming vehicles and pedestrians. The design of the visor also takes into account aerodynamic factors, which helps to reduce wind resistance and improve vehicle driving stability. It is an important accessory for improving driving safety and enhancing lighting effects.

[0003] Referring to the Chinese patent CN204943347U for an anti-glare structure for LED automotive lights, it includes a grid cover with light reflection function and a diffuser cover with light diffusion function. The grid cover is honeycomb-shaped, and the inner surface of the light-emitting surface of the diffuser cover is provided with a plurality of light diffusion protrusions. Both the diffuser cover and the grid cover are circular. In this application, the grid cover is honeycomb-shaped, with a large number of reflective surfaces and a large reflective area, which can diffuse the light emitted by the LED light source, increase the illumination area, make the light softer, reduce the glare effect, and play an anti-glare role. The diffuser cover is provided with light diffusion protrusions, which can diffuse the light outward, increase the light illumination angle, increase the light illumination area, and scatter the light emitted by the automotive lights in all directions, making them easier for people to see and reducing the probability of traffic accidents.

[0004] In actual use, the aforementioned patented anti-glare structure for LED automotive lights has weak heat dissipation capacity. Prolonged continuous use will cause the anti-glare structure for LED automotive lights to maintain a high temperature, affecting the service life of the anti-glare structure for LED automotive lights.

[0005] Further reference is made to Chinese Patent No. CN223137674U, which discloses a heat dissipation structure for an automotive lamp, including a cooling fan. The blades are movably connected to the inner side of the air guide cover via bearings. Cavities are provided on both the left and right sides of the heat dissipation cover, and sliding rods are fixedly installed on the outer side of the top of each cavity. Airflow is generated by the cooling fan, and the heat inside the lamp body is dissipated outward through the ventilation holes, the air guide cover, and the blades. Since the cooling fan is inside the heat dissipation cover, it does not obstruct the light-transmitting lamp cover and does not affect the light transmission effect of the light-transmitting lamp cover. It is easy to disassemble the heat dissipation cover to clean the dust inside the heat dissipation cover and the light-transmitting lamp cover, thereby improving the heat dissipation effect of the cooling fan and improving the overall practicality.

[0006] However, during the heat dissipation process of the aforementioned patented heat dissipation structure, the area covered by the sunshade is not in a sealed state while actively driving airflow to expel heat. In this unsealed state, the light-emitting area of ​​the car headlights is easily invaded by moisture, which can easily cause dust accumulation and is also prone to corrosion. Utility Model Content

[0007] The purpose of this invention is to provide a car headlight anti-scattering light shield. Direct start of the fan can draw in external gas. After the external gas is gathered through the connecting frame, it is transported in the heat pipe. The gas transported in the heat pipe will directly contact and transfer heat to the heat pipe. Heat dissipation can be achieved at the light-emitting position of the car headlight while sealing the car headlight. It can efficiently cool the area around the light-emitting position of the car headlight and solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a car headlight anti-scattering sunshade, including a front sunshade, a rear sunshade is provided at the rear end of the car headlight, a shielding ring is provided around the rear sunshade and the front sunshade, the shielding ring is welded and fixed to the rear sunshade by a connecting ring, and the rear sunshade, the connecting ring and the shielding ring are welded and fixed in sequence, a heat-conducting pipe is provided inside the connecting ring, and a grille cover is provided at the front end inside the front sunshade.

[0009] Preferably, the four corners of the rear and front sunshades are fixedly connected by bolts.

[0010] Preferably, a pre-drilled hole is provided at the middle position of the shielding ring.

[0011] Preferably, one end of the heat pipe is provided with a connecting frame, and the other end of the heat pipe passes through the rear light shield and extends to the upper end of the rear light shield.

[0012] Preferably, the connecting frame is located at the lower end of the rear sunshade.

[0013] Preferably, a fan is provided at one end of the connecting frame.

[0014] Preferably, a second bracket is provided between the lower end of the outer side of the connecting frame and the outer wall of the rear sunshade, and the two ends of the second bracket are welded and fixed to the connecting frame and the front sunshade, respectively.

[0015] Preferably, the outer wall of the fan is fixedly connected to the connecting frame by bolts.

[0016] Preferably, connecting frames are provided on both sides of the rear end of the rear sunshade, and the connecting frames are fixedly connected to the rear sunshade by bolts.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the application of this invention to automotive headlights, the front and rear ends of the headlight are respectively enclosed by a front sunshade and a rear sunshade. Heat is absorbed by the surrounding heat-conducting pipes. For heat dissipation around the headlight, the direct activation of a fan draws in external gas. This gas, after being collected by the connecting frame, is then transported within the heat-conducting pipes. The gas transported within the heat-conducting pipes directly contacts and transfers heat to the pipes. This allows for heat dissipation of the headlight's luminous area even when the headlight is sealed, efficiently cooling the area around the luminous area. This design allows for long-term use at high temperatures and improves the safety of the headlight during operation. Attached Figure Description

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] like Figure 1 As shown in the figure, an anti-scattering sunshade for a car headlight in this embodiment includes a front sunshade 1, with a car headlight disposed at the rear end of the front sunshade 1, and a rear sunshade 2 disposed at the rear end outside the car headlight. The rear sunshade 2 and the front sunshade 1 can cover and protect the car headlight. The four corners of the rear sunshade 2 and the front sunshade 1 are fixedly connected by bolts. The bolts pass through the four corners of the rear sunshade 2 and the front sunshade 1, and the nuts are rotated to the outside of the bolts to complete the fixation. The rear sunshade 2 and the front sunshade 1 can be fixed together, and the car headlight in the middle position can be covered and protected by the rear sunshade 2 and the front sunshade 1.

[0027] To dissipate heat from the vehicle headlights enclosed by the rear sun visor 2 and the front sun visor 1, a shielding ring 9 is provided around the area between the rear sun visor 2 and the front sun visor 1. The shielding ring 9 is welded to the rear sun visor 2 via a connecting ring 8. The rear sun visor 2, the connecting ring 8, and the shielding ring 9 are welded together in sequence. The connection via the connecting ring 8 facilitates the shielding ring 9 to enclose the vehicle headlights, collecting and dissipating the heat generated by the vehicle headlights without obstructing their illumination.

[0028] Furthermore, a reserved hole 12 is provided in the middle of the shielding ring 9. The reserved hole 12 makes it easy to expose the car headlights, so that the car headlights can produce light after being powered on.

[0029] It is worth mentioning that, such as Figure 3 and Figure 4 As shown, a heat-conducting pipe 6 is arranged around the inside of the connecting ring 8. The heat wrapped by the connecting ring 8 can be directly transferred to the heat-conducting pipe 6, which facilitates cooling from the heat-conducting pipe 6.

[0030] In this embodiment, a connecting frame 5 is provided at one end of the heat pipe 6, and the other end of the heat pipe 6 passes through the rear light shield 2 and extends to the upper end of the rear light shield 2. The connecting frame 5 is located at the lower end of the rear light shield 2. After the air for heat dissipation is sent into the interior of the heat pipe 6 through the connecting frame 5, the heat transferred to the interior of the heat pipe 6 can be discharged from the heat pipe 6 at the upper end of the rear light shield 2.

[0031] To provide gas flow for active heat dissipation, such as Figure 2 As shown, a fan 4 is provided at one end of the connecting frame 5. The start of the fan 4 can draw in external gas, so that the gas can be actively sent into the heat pipe 6, so that the gas actively enters the heat pipe 6, carries heat, and is discharged from the other end of the heat pipe 6.

[0032] To improve the stability of the fan 4 during installation, a second bracket 13 is provided between the lower end of the connecting frame 5 and the outer wall of the rear light shield 2. The two ends of the second bracket 13 are welded and fixed to the connecting frame 5 and the front light shield 1, respectively. The support of the second bracket 13 can facilitate the stability of the fan 4 after connection. The outer wall of the fan 4 and the connecting frame 5 are fixedly connected by bolts. The fan 4 can be fixed by passing the bolts through the fan 4 and the connecting frame 5 in sequence. This can maintain a stable gas flow inside the heat pipe 6 and achieve efficient heat dissipation at the location wrapped by the connecting ring 8.

[0033] To assist in heat dissipation of the area enclosed by the front sunshade 1 and the rear sunshade 2, a heat sink 11 is provided horizontally on the outer wall of the rear sunshade 2, and the heat sink 11 is welded and fixed to the rear sunshade 2. After the heat is conducted through the rear sunshade 2 and the heat sink 11, the heat sink 11 can directly dissipate the heat to the outside, thereby achieving heat dissipation assistance.

[0034] To facilitate the connection of the front sunshade 1 and the rear sunshade 2 enclosure structure, connecting brackets 3 are provided on both sides of the rear end of the rear sunshade 2, and the connecting brackets 3 are fixedly connected to the rear sunshade 2 by bolts. The extended connecting brackets 3 facilitate the fixing of bolts and make it easy to fix the entire structure in the required position.

[0035] To prevent car headlights from scattering light, such as Figure 5 As shown, a grille cover 7 is provided at the front end of the interior of the front sunshade 1. The grille cover 7 has a honeycomb structure inside, with a large number of reflective surfaces and a large reflective area, which can diffuse the light emitted by the light source, increase the illumination area, make the light softer, and reduce glare. Referring to the Chinese patent for anti-glare structure for LED automotive lights with publication number CN204943347U, the grille cover 7 is described in detail in that application. That application is equivalent to the prior art in this application, so the structure of the grille cover 7 is not described in detail in this application.

[0036] To facilitate the connection between the rear sunshade 2 and the car headlight in the middle position, a first bracket 10 is provided at each of the four corners inside the front sunshade 1. One end of the first bracket 10 is welded and fixed to the inner wall of the rear sunshade 2, and the other end of the first bracket 10 is connected to the four corners of the car headlight through slots. The first bracket 10 and the car headlight are fixedly connected by bolts. The first bracket 10 can be used to support and connect the car headlight. While supporting and connecting, the rear end of the car headlight can be suspended to facilitate heat dissipation.

[0037] Working principle: When using light shields to cover and protect the light-emitting position, the front light shield 1 and the rear light shield 2 cover and protect the front and rear ends of the light-emitting position. The four corners of the front light shield 1 are fixedly connected by bolts. The heat generated at the rear light-emitting position is transferred through the air and comes into contact with the heat-conducting pipe 6. The fan 4 supported by the second bracket 13 is started. The fan 4 draws in the external gas and gathers the gas through the connecting frame 5 and transfers it in the heat-conducting pipe 6. The gas is transferred through the heat-conducting pipe 6 and discharged directly from one end of the heat-conducting pipe 6. During the high-speed flow of the gas in the heat-conducting pipe 6, the heat transferred to the heat-conducting pipe 6 is directly discharged, realizing heat dissipation of the light-emitting position under the sealed state of the front light shield 1 and the rear light shield 2.
