Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamp testing, in particular to a vehicle lamp testing device. Background Art

[0002] During the testing of car lights, engineers need to build a test environment. This process involves connecting the car lights, debugging tools, and CAN bus to the electronic control unit (ECU), and using the built test environment to test whether the car lights function normally. This test method includes but is not limited to testing whether the car lights can be lit and whether they work normally according to design requirements. In this setting, the CAN bus is used to transmit control commands and feedback signals, and the debugging tool is used to monitor and modify the ECU parameter settings in real time. The tester sends instructions to the ECU or directly controls it through the debugging tool to observe whether the car lights can light up, change brightness or function mode in response to the correct signals. The integrity of the test environment and the effectiveness of the debugging tool are key factors to ensure that the car lights can work normally in actual use. To this end, we need to provide car light testing equipment.

[0003] Currently, headlights are tested on a test bench, with testers directly observing the lighting status of the headlights. This direct exposure to strong headlight light can easily damage the tester's eyes. In particular, prolonged staring at high-brightness headlights can cause eye fatigue, stinging, or even impaired vision. This not only affects the health and safety of the tester, but also the accuracy and efficiency of the headlight testing process. Utility Model Content

[0011] Furthermore, the system further comprises a first installation box, wherein the first installation box is installed in the box body, and the headlight ECU is placed in the first installation box, thereby ensuring that the headlight ECU remains stable, facilitating subsequent testing operations of the headlight.

[0012] Furthermore, the vehicle light ECU is provided with a temperature sensor.

[0013] Furthermore, it also includes: an interface, and the control terminal is connected to the vehicle light ECU through the interface.

[0014] Furthermore, the system further comprises a second installation box installed in the box body. Thus, the headlight and the headlight ECU are connected via a wiring harness, and redundant wiring harnesses are located in the second installation box to avoid wiring harness clutter.

[0027] like Figures 1 to 4 As shown, it is the optimal embodiment of the present utility model. The headlight testing device of this embodiment includes: a box body 1, a fixing seat 2, a headlight ECU3 and a sunshade 5. The box body 1 is provided with a box door 101, the fixing seat 2 is installed in the box body 1, the fixing seat 2 is used to carry the lamp, the headlight ECU3 is installed in the box body 1, the headlight ECU3 is connected to the control terminal 4, the control terminal 4 tests the lamp through the headlight ECU3, and the sunshade 5 is installed on the top of the box body 1; wherein: during the test, the box body 1 is in a closed state, and the light emitted by the lamp is irradiated through the sunshade 5. Therefore, during the test, the light emitted by the lamp is blocked by the sunshade 5. Compared with the existing bench-type direct light testing method, this method has a simple structure and is easy to operate. The tester does not need to look directly at the light emitted by the lamp. On the one hand, it can avoid the strong light of the car lamp directly hitting the tester and causing damage to the tester's eyes. On the other hand, it can avoid the tester from looking directly at the high-brightness car lamp for a long time, causing eye fatigue, stinging and even vision damage to the tester, thereby ensuring the safety of the entire test process. At the same time, it can also improve the test accuracy and test efficiency.

[0028] For example, the model of the main control MCU of the headlight ECU 3 is Z20K144M; the sunshade 5 is made of black resin.

[0029] In this embodiment, the device further includes a carrier plate 6 and a fixing plate 13. The carrier plate 6 is mounted within the housing 1 and connected to a fixing base 2. The fixing plate 13 is mounted within the housing 1 and connected to the carrier plate 6 and the fixing base 13. Specifically, the fixing base 2 is used to securely secure the vehicle lamp to the carrier plate 6, ensuring that the vehicle lamp does not move during testing.

[0030] In this embodiment, the system further includes a cooling fan 7, cooling holes 8, and heat sink 9. The cooling fan 7 is mounted on one side wall of the housing 1, the cooling holes 8 are formed on another side wall of the housing 1, and the heat sink 9 is mounted within the housing 1. The heat sink 9 is located on a side of the carrier 6 away from the fixing base 2 and is connected to the heat sink 9. The cooling fan 7 is connected to the headlight ECU 3, and the heat sink 9 is connected to the headlight ECU 3. Therefore, during the headlight test, if the headlight temperature is too high, the cooling fan 7 and heat sink 9 are activated to cool the headlight together, thereby preventing the headlight from overheating due to long-term operation or high-power operation, thereby extending the life of the headlight. At the same time, the performance of the headlight is not affected, and the risk of a decrease in headlight brightness due to overheating, or even failure or damage to the headlight, is avoided.

[0031] This embodiment also includes a first mounting box 10 and a second mounting box 12. The first mounting box 10 is mounted on the housing 1, the headlight ECU 3 is located within the first mounting box 10, and the second mounting box 12 is located within the housing 1. This ensures that the headlight ECU 3 remains stable, facilitating subsequent headlight testing. The headlight and headlight ECU 3 are connected via a wiring harness, with excess wiring located in the second mounting box 12 to avoid wiring clutter.

[0032] In this embodiment, the vehicle lamp ECU 3 is provided with a temperature sensor 301 .

[0033] In this embodiment, the system further includes an interface 11 , through which the control terminal 4 is connected to the vehicle light ECU 3 .

[0034] In this embodiment, it further includes: a power supply 14, to which the vehicle lamp, the vehicle lamp ECU 3, the cooling fan 7 and the heat sink 9 are all connected. The power supply 14 provides power for the operation of the entire vehicle lamp testing device.

[0035] The testing process of the headlight of the present invention is: first, open the box door 101, install the headlight to be tested on the fixing seat 2, and place the headlight ECU3 in the first installation box 10; then, connect the headlight and the headlight ECU3 through the wiring harness, and place the excess wiring harness in the second installation box 12; then, close the box door 101; then, insert the CAN line into the interface 11 to connect the headlight ECU3 with the control terminal 4; finally, start the power supply 14, and control the headlight ECU3 through the control terminal 4 to light up the headlight, change the brightness or test the functional mode. The tester observes the test results of the headlight through the sun visor 5. At the same time, if the temperature sensor 301 detects that the temperature of the headlight is too high, the temperature sensor 301 sends a signal that the headlight temperature is too high to the headlight ECU3, and the headlight ECU3 sends a signal to the cooling fan 7 and the heat sink 9 to control the cooling fan 7 and the heat sink 9 to start and cool down the headlight with too high temperature.

[0036] To sum up, during testing, the present invention blocks the light emitted by the lamp through the sunshade 5. Compared with the existing bench-type direct light testing method, this method has a simple structure and is easy to operate. The tester does not need to look directly at the light emitted by the lamp. On the one hand, it can avoid the strong light of the car lamp directly hitting the tester and causing damage to the tester's eyes. On the other hand, it can avoid the tester from looking directly at the high-brightness car lamp for a long time, causing eye fatigue, stinging and even vision damage to the tester, thereby ensuring the safety of the entire test process. At the same time, it can also improve the test accuracy and test efficiency.
