Description

Technical Field

[0001] This utility model relates to the field of automotive rearview mirror blind spot light technology, specifically a heat dissipation structure for automotive blind spot lights. Background Technology

[0002] Car rearview mirrors typically use a slightly curved mirror surface, usually located on both sides of the front of the vehicle. Drivers can see the traffic and road conditions behind the car through the mirror. However, due to varying degrees of blind spots and insufficient field of vision, drivers often have to lean forward or turn their heads left and right to spot obstacles when turning, changing lanes, overtaking, or being overtaken, posing a potential safety hazard. A small light on the rearview mirror is part of the blind spot monitoring and warning system. This light illuminates when a moving obstacle is approaching or moving away from the side or rear of the vehicle, alerting the driver to the presence of vehicles or pedestrians in the blind spot and prompting caution when changing lanes or turning to avoid traffic accidents caused by blind spots. While the structure of traditional blind spot lights on car rearview mirrors generally meets basic user needs, certain problems still exist.

[0003] The authorized patent with announcement number CN218033040U discloses a structure for a blind spot light for a car rearview mirror, relating to the field of blind spot light technology for car rearview mirrors. It includes a car rearview mirror body, a BSD connector body, a heating element terminal, and a heating element terminal. The car rearview mirror body has an internal mounting groove, and the BSD connector body is installed inside the mounting groove. The heating element terminal is also installed inside the car rearview mirror body, and connecting wires are arranged horizontally inside the car rearview mirror body. However, because the above device lacks a heat dissipation structure, the blind spot light will generate a large amount of heat after prolonged use. If heat dissipation is not carried out, it may cause a short circuit in the blind spot light, rendering it unusable and reducing safety performance.

[0004] Therefore, a heat dissipation structure for automotive blind spot lights is proposed here. Utility Model Content

[0005] The purpose of this utility model is to provide a heat dissipation structure for automotive blind spot lights, so as to solve the problem mentioned in the background art that if heat dissipation is not carried out, the blind spot lights may short circuit.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation structure for automotive blind spot lights, comprising a rearview mirror body and a mounting box, wherein the mounting box is fixedly connected to the inner side of the rearview mirror body, a BSD connector body is fixedly connected to the inner side of the rearview mirror body, a connecting wire is fixedly connected to the outer side of the BSD connector body, an air intake pipe is fixedly connected to the inner side of the rearview mirror body and arranged sequentially from left to right, the air intake pipe penetrates the inner cavity of the rearview mirror body and extends to the outer side of the rearview mirror body, a long corrugated plate is fixedly connected to the inner side of the air intake pipe, and an air outlet pipe is fixedly connected to the inner side of the rearview mirror body and arranged sequentially from top to bottom, the air outlet pipe penetrates the inner cavity of the rearview mirror body and extends to the outer side of the rearview mirror body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The heat dissipation structure of this automotive blind spot light allows outside air to enter the mounting box through the intake pipe when the car is moving. Under the guidance of the deflector, the air flows along the inside of the mounting box, carrying away the heat generated by the blind spot light body through the exhaust pipe. When the vehicle speed is too high, the long corrugated plate can block and slow down the incoming air. In conjunction with the waterproof mesh, rainwater can be blocked. Even if rainwater manages to enter, it can be intercepted inside the intake pipe by the long corrugated plate. The movement of the vehicle can drive outside air to dissipate heat from the blind spot light body, thus improving the heat dissipation performance.

[0015] 2. The blind spot light uses a heat dissipation structure. After prolonged use, the blind spot light body will generate a lot of heat. Through the cooperation of the heat sink and heat dissipation ring, the generated heat can be absorbed and evenly distributed. The heat is then introduced into the outside air through the air intake pipe, and the heat dissipated by the heat sink and heat dissipation ring is carried out through the air outlet pipe, which improves the heat dissipation efficiency and enhances safety.

The heat is then introduced into the outside air through the air inlet pipe 120, and the heat dissipated by the heat sink 212 and the heat dissipation ring 220 is carried out through the air outlet pipe 130, thereby improving the heat dissipation efficiency and enhancing safety.

[0036] In practical use, when the car is in motion, outside air enters the mounting box 200 through the intake pipe 120 and flows inside the mounting box 200 under the guidance of the deflector 231. The heat generated by the blind spot lamp body 210 is carried away through the exhaust pipe 130. When the vehicle speed is too high, the long corrugated plate 121 can block and slow down the incoming air. In conjunction with the waterproof mesh 132, rainwater can be blocked. Even if rainwater manages to enter, it can be intercepted inside the intake pipe 120 by the long corrugated plate 121. The movement of the vehicle can drive outside air to dissipate heat from the blind spot lamp body 210. After prolonged use, the blind spot lamp body 210 will generate a lot of heat. Through the cooperation of the heat sink 212 and the heat dissipation ring 220, the generated heat can be absorbed and evenly dispersed. Outside air is introduced through the intake pipe 120, and the heat emitted by the heat sink 212 and the heat dissipation ring 220 is carried out through the exhaust pipe 130, thereby improving the heat dissipation efficiency.

[0037] It should be noted that the BSD connector body 110 and blind spot light body 210 mentioned in the article are both existing technologies. The principle of the BSD connector body 110 is as follows: the car BSD uses millimeter-wave radar to detect blind spots on both sides of the rear of the vehicle. When other vehicles enter the blind spot range, it will provide the driver with light prompts and a buzzer alarm in the rearview mirror or a designated location to inform the driver of the best time to close the lane and avoid traffic accidents caused by merging. The principle of the blind spot light body 210 is as follows: it detects objects around the vehicle through radar, cameras, ultrasonic sensors, etc., and the electronic control unit (ECU) analyzes and processes the data to identify objects in the blind spot and then reminds the driver through a warning mechanism.
