Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp covers, in particular to a wide-angle vehicle high-beam lamp cover. Background Art

[0002] The high beam on a car is a lighting device that is usually used to improve the driver's vision and ensure driving safety when driving at night. The high beam is relatively strong and can illuminate the road far ahead. It is an indispensable safety tool for people when driving on the road.

[0003] In Chinese Patent 202223215714.3, the present application discloses an automobile lampshade, which relates to the field of lampshade technology. The present application includes an outer lampshade and an inner lampshade, wherein the inner side of the outer lampshade is constructed with a fixing block fixed to the front of the automobile by bolts, a sealing gasket is laid along the bottom edge of the outer lampshade, and a connecting block is also provided on the inner side of the outer lampshade. The present application can improve the sealing of the overall automobile lampshade by setting the sealing gasket, thereby preventing rainwater and dust from entering the automobile lampshade, thereby reducing the source of fog inside the automobile lampshade, and thereby reducing the fogging phenomenon inside the automobile lampshade. The setting of the air inlet and the air outlet allows the air to circulate inside and outside, thereby reducing the temperature difference between inside and outside, and thereby reducing the occurrence of fogging inside the automobile lampshade. The setting of the waterproof air inlet membrane can intercept the rainwater entering the filter, so that it cannot enter the interior of the automobile lampshade, thereby reducing the number of fogging inside the automobile lampshade.

[0004] The existing automobile high beam lampshade has a waterproof air inlet membrane at the position of the air inlet hole to prevent external water vapor from entering the interior of the lampshade. However, the waterproof air inlet membrane is usually thin and fragile. During the car washing process, if it is impacted by high-pressure water flow, it is very easy to be damaged. In addition, the waterproof air inlet membrane in the existing lampshade is directly fixed inside the air inlet hole and cannot be disassembled and replaced. When a problem occurs with one of the air inlet membranes, the waterproofness of the entire lampshade will have problems, and the entire lampshade needs to be disassembled and replaced, which has a high maintenance cost. In addition, the existing exhaust hole is arranged in a U shape, and it is equally difficult for the outside air to enter the lampshade and the air inside the lampshade to be discharged. Therefore, the outside air may still enter the lampshade from the exhaust hole, and at the same time bring some water vapor into the lampshade from the air outlet, causing the problem of fogging inside the lampshade.

[0005] Therefore, in view of the above problems, a wide-angle automobile high-beam lampshade is proposed. Utility Model Content

[0006] In order to make up for the shortcomings of the prior art, a waterproof air intake membrane is provided at the position of the air intake hole of the existing automobile high beam lampshade to prevent external water vapor from entering the interior of the lampshade. However, the waterproof air intake membrane is usually thin and fragile. During the car washing process, if it is impacted by high-pressure water flow, it is very easy to be damaged. In addition, the waterproof air intake membrane in the existing lampshade is directly fixed inside the air intake hole and cannot be disassembled and replaced. When a problem occurs with one of the air intake membranes, the waterproofness of the entire lampshade will have problems. The entire lampshade needs to be disassembled and replaced, and the maintenance cost is high. In addition, the existing exhaust hole is arranged in a U shape, and the difficulty for external air to enter the lampshade is equal to the difficulty for the air inside the lampshade to be discharged. Therefore, external air may still enter the lampshade from the exhaust hole, and at the same time bring some water vapor into the lampshade from the air outlet, causing the problem of fogging inside the lampshade.

When blocked or damaged, the damaged one can be replaced, which does not affect the use of the entire lampshade, and is convenient for saving maintenance costs;

[0016] 2. The utility model is provided with a lampshade exhaust hole assembly. When the air pressure inside the lampshade is greater than the external air pressure, the airflow can push open the blocking cover and flow out under the action of the air pressure. However, the ring opening of the blocking cover is larger than the aperture of the exhaust hole. That is to say, the external airflow cannot push open the blocking cover and enter the interior of the lampshade, so as to prevent the water vapor carried by the airflow from entering the lampshade through the exhaust hole and causing fogging inside the lampshade.

[0029] See also Figure 3 and Figure 4As shown, a wide-angle automobile high-beam lampshade, the lampshade air inlet hole assembly 2 is used to allow outside air to enter the interior of the lampshade to form an airflow to remove heat, the heat dissipation air inlet hole 204 is shaped as a trumpet, and the heat dissipation air inlet hole 204 forms a threaded detachable structure with a threaded joint 203 and a threaded ring 202, and the threaded ring 202 is arranged at equal intervals with respect to the inside of the air inlet hole support plate 201, and a sealing gasket is arranged at the place where the heat dissipation air inlet hole 204 is connected to the automobile lampshade body 1, and when the heat dissipation air inlet hole 204 is tightened and fixed, a squeezing force will be generated on the sealing gasket, thereby preventing heat dissipation. There is a gap between the air intake hole 204 and the automobile lampshade body 1, and the heat dissipation air intake hole 204 is arranged in a trumpet shape, which makes it easier for outside air to flow into the interior of the automobile lampshade body 1 during driving of the automobile, thereby forming a circulating airflow inside the automobile lampshade body 1, and taking out the heat from the automobile lampshade body 1. Each heat dissipation air intake hole 204 is fixed to the lampshade by a separate threaded ring 202 and a threaded joint 203, and can be disassembled and replaced separately. When blockage or damage occurs, the damaged one can be replaced without affecting the use of the entire lampshade, which is convenient for saving maintenance costs.

[0030] See also Figure 6 As shown, a wide-angle automobile high-beam lampshade, the lampshade exhaust hole assembly 4 includes an exhaust hole 401, the exhaust hole 401 is fixedly connected with a fastening spring 402 inside, and the top of the fastening spring 402 is fixedly connected with a sealing pad 403, and the outside of the sealing pad 403 is integrally connected with a blocking cover 404, the blocking cover 404 forms an elastic structure with the exhaust hole 401 through the fastening spring 402, and the blocking cover 404 forms a sealing structure with the exhaust hole 401 through the sealing pad 403, when the air pressure inside the lampshade is greater than the external air pressure, under the action of the air pressure, the airflow can push open the blocking cover 404 and flow out, however, the circle of the blocking cover 404 is larger than the aperture of the exhaust hole 401, that is, the external airflow cannot push open the blocking cover 404 inward to enter the interior of the lampshade, so as to prevent the water vapor carried in the airflow from entering the lampshade from the exhaust hole and causing fogging inside the lampshade.

[0031] See also Figure 5As shown, a wide-angle automobile high-beam lampshade, an air inlet protection component 3 includes a slide groove 301, a protective baffle 302 is slidably connected inside the slide groove 301, and a push block 303 is fixedly connected to the end of the protective baffle 302, the protective baffle 302 forms a sliding structure with the automobile lampshade body 1 through the slide groove 301, and two slide grooves 301 are symmetrically arranged about the horizontal center axis of the automobile lampshade body 1, and the slide groove 301 and the automobile lampshade body 1 are integrated.

When the car is driving forward, the outside air will enter the interior of the automobile lampshade body 1 from the heat dissipation air intake hole 204, and the heat dissipation air intake hole 204 is trumpet-shaped. The airflow will gradually be contracted during the entry process, thereby increasing the flow rate. When the outside airflow enters the interior of the automobile lampshade body 1, or the temperature inside the automobile lampshade body 1 increases due to the use of the high beam, the gas expands and the internal air pressure increases, the airflow inside the automobile lampshade body 1 will push open the blocking cover 404 under the action of the air pressure, and then be discharged from the blocking cover 404, and the air circulates from the inside of the automobile lampshade body 1 to take out the heat inside the automobile lampshade body 1;

[0033] When using a flushing gun to clean the car, the protective baffle 302 can be slid between the two slide grooves 301. At this time, the protective baffle 302 just blocks the outside of the heat dissipation air intake hole 204, so that the high-pressure water flow cannot directly impact the waterproof air intake membrane 205. If the waterproof air intake membrane 205 is still damaged or blocked after long-term use, the lampshade can be removed first, and then the damaged waterproof air intake membrane 205 can be found, and the corresponding threaded joint 203 can be unscrewed, so that the heat dissipation air intake hole 204 can be removed, and then the new heat dissipation air intake hole 204 and the waterproof air intake membrane 205 can be replaced.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
