Description

Technical Field

[0001] This utility model relates to the field of automotive sunshade components, specifically an automotive sunshade component with ventilation and heat dissipation functions. Background Technology

[0002] Direct stimulation from sunlight and strong nighttime lights causes a lot of visual fatigue and interference for car drivers. Although there are sunshades and some extension covers on the market that can help drivers reduce the stimulation of strong light;

[0003] Chinese Patent Publication No. CN206155103U discloses a car sunshade and a car. The first objective of this invention is to provide a car sunshade comprising a light-transmitting cover, a storage compartment, and a power unit. When driving at night, if an oncoming vehicle's driver has not turned off their high beams, the cover within the storage compartment can be unfolded via the power unit to block or reduce the intensity of the oncoming vehicle's high beams without affecting visibility, thus preventing glare and ensuring driving safety. After passing the oncoming vehicle, the cover can be retracted into the storage compartment by controlling the power unit, allowing for normal driving. This invention also provides a car including the aforementioned car sunshade. The car sunshade provides increased safety during nighttime driving, reducing the likelihood of accidents.

[0004] After prolonged use, the sunshade of the aforementioned patent is continuously illuminated by the headlights of the vehicle, which causes the light energy to be converted into heat energy and conducted to the sunshade, resulting in an increase in the surface temperature of the sunshade. Traditional sunshades lack a heat dissipation structure. Utility Model Content

[0005] The purpose of this invention is to provide a car sunshade assembly with ventilation and heat dissipation functions. A rectangular groove is formed on the inner wall of the sunshade, and a reflective baffle is installed within the rectangular groove. A ventilation groove is formed between the reflective baffles, and ventilation holes are formed on the reflective baffles, penetrating both the reflective baffles and the sunshade. A sunshade plate is installed on the outer surface of the sunshade at a corresponding position in the rectangular groove, and the sunshade plate is connected to the sunshade by bolts. When the sunshade is installed on the headlight assembly, the airflow during vehicle operation is forced into the ventilation holes by wind resistance. The airflow then enters the ventilation groove between the reflective baffles, impacts the reflective baffle surface, and disperses within the sunshade, reducing the temperature inside the sunshade and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a car sunshade assembly with ventilation and heat dissipation function, including a sunshade cover, a rectangular groove on the sunshade cover, a reflective baffle disposed in the rectangular groove, a ventilation groove between the reflective baffles, and a first ventilation hole on the reflective baffle. The first ventilation hole is disposed on the reflective baffle. The sunshade cover has a second ventilation hole at a corresponding position on the rectangular groove. A sunshade plate is disposed on the outer surface of the sunshade cover, a second bolt hole is disposed on the sunshade plate, and a first bolt hole is disposed on the outer surface of the sunshade cover at a corresponding position on the second bolt hole.

[0007] Preferably, the light shield has a mounting groove, and the mounting groove is integrally formed with the light shield.

[0008] Preferably, a connecting base is provided at the bottom end of the inner wall of the mounting groove.

[0009] Preferably, the connecting base is provided with a wiring conduit, which is welded to the connecting base.

[0010] Preferably, the inner wall of the conduit is provided with connecting threads.

[0011] Preferably, the wiring conduit has an interface.

[0012] Preferably, the light shield has a wiring hole.

[0013] Preferably, a connecting rod is provided on the outer surface of the light shield, and the connecting rod is welded to the light shield.

[0014] Preferably, the connecting rod has an installation groove on the end away from the sunshade.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention features a rectangular groove on the inner wall of a sunshade, within which reflective baffles are installed. Ventilation slots are formed between the reflective baffles, and ventilation holes are formed on the reflective baffles, penetrating both the reflective baffles and the sunshade. A sunshade plate is positioned on the outer surface of the sunshade at a corresponding position within the rectangular groove, and the sunshade plate is connected to the sunshade by bolts. When the sunshade is installed on the vehicle headlight assembly, airflow is forced into the ventilation holes by wind resistance during vehicle operation. The airflow then enters the ventilation slots between the reflective baffles, impacts the reflective baffle surfaces, and disperses within the sunshade, reducing the temperature inside the sunshade. This effectively avoids the problem of existing sunshades, which, after prolonged use, are constantly exposed to vehicle headlights, causing light energy to be converted into heat energy and conducted to the sunshade surface, leading to an increase in surface temperature. Traditional sunshades lack a heat dissipation structure. Attached Figure Description
