Description

Technical Field

[0001] The utility model belongs to the field of automobiles, and in particular relates to a sunroof sunshade droop detection system. Background Art

[0002] With the rapid development of the automobile industry, consumers have higher and higher requirements for automobile comfort, prompting automobile manufacturers to make improving vehicle comfort an important direction for automobile technology research and development. The car sunroof is an important component to increase the comfort of the car. The car sunroof includes a sunshade. The droop of the sunshade is an important indicator for judging the performance of the sunshade. Specifically, when the droop of the sunshade is too large, it will occupy the interior space of the vehicle on the one hand, and affect the beauty of the interior on the other hand; when the droop of the sunshade is too small, it means that the sunshade is in a tight state, which may cause the sunshade to tear and create a safety hazard.

[0003] In the research and development of automobile sunroofs, it is necessary to test the droop of the sunshade so as to control the droop of the sunshade within a reasonable range and ensure the performance of the sunshade.

[0004] The current method for detecting the droop of the sunshade is to install the skylight on a test fixture and use a distance detector to detect the droop of the sunshade. This method has the following disadvantages:

[0005] 1. The inspection fixture can only inspect skylights of one size and cannot inspect skylights of different sizes.

[0006] 2. The use of a fixture to test the sunshade simulates the environment of the vehicle body, not the actual environment of the vehicle body, and cannot simulate the actual working conditions of the sunroof installed on the vehicle body. Therefore, there is a discrepancy with the actual result, that is, a sunshade that passes the inspection of the fixture cannot guarantee that it will also pass the inspection when installed on the vehicle body. In addition, the fixture cannot participate in the sunroof development experiment.

[0007] 3. Using a testing fixture to test the skylight cannot simulate working conditions of -20℃ to 90℃.

[0008] 4. Unable to record test data in real time. Summary of the invention

[0009] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a sunroof sunshade droop detection system. In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
