Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically to a heat dissipation testing device for automotive lamp covers. Background Technology

[0002] Automotive headlight thermal protection refers to the protective measures taken when the heat generated by the headlights during operation exceeds a set threshold, in order to prevent abnormal operation or malfunction. Automotive headlight covers are protective devices installed on the outside of automotive headlights, primarily used to protect them from damage by the external environment while also enhancing the vehicle's aesthetic appearance.

[0003] Most existing automotive lamp covers are used to protect the internal structure and have a certain heat dissipation performance. They are used in conjunction with thermal protection measures to protect the internal lamp structure from heat dissipation. However, the heat dissipation performance testing process for existing lamp covers is time-consuming, requires manual operation and internal measurement, and has low testing efficiency.

[0004] Therefore, it is necessary to design a heat dissipation testing device for automotive lamp covers that is both practical and allows for rapid testing. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation testing device for automotive lamp covers, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat dissipation testing device for automotive lamp covers, comprising a base, a slide rail above the base, a conveyor above the slide rail, an elevator above the base, a controller slidably connected to the inner side of the elevator, an operating chamber fixedly installed inside the controller, a first cylinder above the operating chamber, an adsorber at the rod end of the first cylinder, and a car lamp adsorbed at the suction cup of the adsorber.

[0007] According to the above technical solution, a first heater is provided on the front side of the adsorber, a second cylinder is provided at the bottom of the operating chamber, and a detector is provided at the end of the cylinder rod.

[0008] According to the above technical solution, a support frame is fixedly installed on the top of the base, a telescopic device is fixedly installed on the front side of the support frame, and a surrounding ring is fixedly installed on the extended end of the telescopic device.

[0009] According to the above technical solution, a heat insulation cover is provided on the inner side of the surrounding ring, and a support connecting plate is provided on the outer side of the support frame. The front of the support connecting plate is connected to the surrounding ring by bearings.

[0010] According to the above technical solution, a support plate is provided on the inner side of the support frame, a guide rail is provided above the support plate, a displacement device is slidably connected above the guide rail, a fan is fixedly installed above the displacement device, and a second heater is provided on the rear side of the fan.

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0012] (1) By setting an adsorber, the first cylinder is equipped with an adsorber at the rod end, and the adsorber adsorbs the car lamp cover at the suction cup. The conveyor can automatically and simply fix the car lamp cover and transport it through the slide rail. After reaching the designated area, the first cylinder extends the rod to drive the adsorber to move forward and adsorb the back of the car lamp cover through the suction cup. Then the conveyor releases the car lamp cover, and then the lifter drives the controller to rise, thereby driving the operating chamber to rise until the car lamp cover is raised to the designated area for inspection, thus realizing automatic transportation and repositioning.

[0013] (2) By setting up a detector, when waiting for detection, the first heater will spray hot air into the inside of the headlight cover to simulate the heat generated when the headlight is turned on, thereby accelerating the internal temperature rise. At the same time, the second cylinder at the bottom extends the rod to drive the detector forward, which can detect the internal temperature change in real time. The detection is divided into four modes: the first mode is the internal temperature rise rate, and the heat dissipation efficiency is judged by the difference between the actual temperature rise rate and the theoretical rate; the second mode is the cooling rate in normal static state, and the heat dissipation efficiency is judged; the third mode is the cooling rate in simulated driving, and the heat dissipation efficiency is judged; the fourth mode is the cooling rate in simulated harsh hot environment driving, and the heat dissipation efficiency is judged by multiple situations and multiple directions.

[0014] (3) By setting up a surrounding ring, the support plate can support the extended surrounding ring to prevent it from falling off. At the same time, the heat insulation cover can isolate the external environment and keep the internal temperature at the system preset value. It also protects the flow direction of hot air and improves detection efficiency. After the fan is turned on, it can blow air to simulate the driving process. At the same time, the distance can be changed to realize different wind speeds for different vehicle speeds. In the fourth mode, the second heater is turned on to transfer heat energy to the fan so that it can blow out hot air. Attached Figure Description
