Description

Technical Field

[0001] This utility model belongs to the technical field of license plate testing equipment, specifically relating to a high and low temperature testing device for license plates. Background Technology

[0002] A license plate, also known as a vehicle registration plate, is a plate that is hung on the front and rear of a vehicle and engraved with the vehicle's registration number, registration area, or other relevant information. Its main function is to indicate the region where the vehicle belongs and to find the owner and registration information of the vehicle through the license plate.

[0003] After production, license plates need to undergo high and low temperature tests to assess the effectiveness of reflective markings under extreme temperatures, the weather resistance of the license plate material, and the stability and reliability of the material at different temperatures. This allows for timely identification and adjustment of problems, ensuring that the product meets relevant temperature resistance testing standards, such as the temperature resistance test mentioned in GA36-2018, thereby improving product quality. However, in existing technologies, license plates are often placed flat in the high and low temperature environment (e.g., inside a high and low temperature test chamber). But placing the license plate flat directly obstructs air circulation, resulting in uneven temperature distribution during the test and affecting the accuracy of the test results.

[0004] Based on this, the applicant is considering designing a high and low temperature test device for license plates that can improve the accuracy of the experiment. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is: how to provide a license plate high and low temperature test device that can improve the accuracy of the experiment.

[0010] The working principle and advantages of the high and low temperature testing device for license plates in this technical solution are as follows:

[0011] During the experiment, the clamping and driving components are installed in a high-temperature or low-temperature testing environment. The two ends of the license plate to be tested are clamped and fixed by the clamping frame to ensure the stability of the license plate during the test. Then, the driving unit is turned on to rotate the driving part. Since the clamping frame is located on the movement trajectory of the driving part, the rotation of the driving part can drive the rotating clamping frame to rotate, thereby causing the license plate inside the clamping frame to rotate. This ensures that all parts of the license plate can be evenly exposed to the ambient temperature in the high-temperature or low-temperature environment, avoiding airflow obstruction and uneven temperature distribution caused by flat placement. This improves the accuracy and reliability of the test results, reduces repeated tests due to uneven temperature, and improves experimental efficiency.

[0013] Furthermore, the clamping member also includes a fixed base, and the clamping frame is rotatably mounted on the fixed base; the first clamping block extends into the fixed base and is connected to its bearing.

[0014] Furthermore, the drive unit includes a drive rod fixedly connected to the output shaft of the drive unit.

[0015] Furthermore, the driving component also includes a mounting base, the driving unit is fixedly installed in the mounting base, and a power supply unit for supplying power to the driving unit is also installed in the mounting base.

[0016] Furthermore, it also includes a mounting bracket, which includes at least two spaced-apart contact plates, with the clamping member and the driving member respectively mounted on the two contact plates on opposite sides of the two contact plates.

[0017] Furthermore, the mounting frame also includes a telescopic component, the two ends of which are fixedly connected to the two contact plates respectively.

[0018] Furthermore, the telescopic component is an elastic telescopic rod, which includes a sleeve and a sleeve. The two ends of the sleeve are slidably connected inside the sleeve, and a compression spring is provided inside the sleeve.

[0019] Furthermore, the clamping member and the driving member are detachably connected to the contact plate, the contact plate is provided with a magnetic attraction part, the magnetic attraction part is magnetically connected to the fixing seat and the mounting seat; the contact plate is provided with a positioning ring for the mounting seat or the fixing seat to be embedded in.

[0037] Refer to together Figures 1-10 This embodiment provides a high and low temperature test device for license plates, which includes a clamping member 200 and a driving member 300 installed opposite to each other;

[0038] The clamping member 200 includes a rotatably mounted clamping frame for clamping both ends of the license plate 10;

[0039] The drive unit 300 includes a drive section and a drive unit 311 that drives it to rotate, and the clamping frame is located on the motion trajectory of the drive unit 300.

[0040] In this embodiment, during the experiment, the clamping component 200 and the driving component 300 are installed in a high-temperature or low-temperature test environment, and the two ends of the license plate 10 to be tested are clamped and fixed by the clamping frame to ensure the stability of the license plate 10 during the test. Then, the driving unit 311 is turned on to make the driving part rotate. Since the clamping frame is located on the movement trajectory of the driving component 300, the rotation of the driving part can drive the rotating clamping frame to rotate, thereby driving the license plate 10 inside the clamping frame to rotate. This ensures that all parts of the license plate 10 can be evenly contacted with the ambient temperature in the high-temperature or low-temperature environment, avoiding the problems of airflow obstruction and uneven temperature distribution caused by flat placement, thereby improving the accuracy and reliability of the test results, reducing repeated tests caused by uneven temperature, and improving experimental efficiency.
