Description

Technical Field

[0001] The present invention relates to the technical field of automobile sunroof durability testing, and more specifically to an automobile sunroof durability testing device and a testing method. Background Art

[0002] The automobile sunroof durability test device is a device used to test the durability of automobile sunroofs. The common automobile sunroof durability test device is mainly composed of a bracket, a base, a moving mechanism, a driving device, a data statistics mechanism, a power supply device, and a control system. The specific process of the automobile sunroof durability test device for the automobile sunroof durability test is as follows: during operation, under the action of the power supply device and the control system, the driving device controls the automobile sunroof to slide inside the test frame, and the data statistics mechanism counts the sliding times of the sunroof in real time, as well as the changes in the sunroof data during the sliding process;

[0003] The bracket and the base are used to limit and fix the experimental device. During the use of the experimental device, the driving device applies a pulling force to the experimental device, and the external force is transmitted to the surface of the bracket, thereby causing the bracket and the experimental device to fall off. As a result, data errors occur in the durability test of the automobile sunroof, which in turn causes the invalidity of the experiment and causes certain economic losses. At the same time, during the sunroof durability test, the pressure resistance of the sunroof needs to be tested in real time, and the sunroof pressure resistance test requires a brand-new experimental equipment, which reduces the overall experimental efficiency and increases the overall experimental cost, thereby causing certain economic losses.

3. The test method of the vehicle sunroof durability test device according to claim 2, characterized in that: The following methods are included: Step 1: During operation, the first servo motor (103) inputs current to generate a rotational force to drive the transmission screw (104) to perform a synchronous rotation operation. The transmission screw (104) in a rotating state drives the first slider (105) to slide on the inner wall of the slide rail (102). The slide rail (102) drives the limiting mechanism (2) to move toward the test frame (106). The limiting mechanism (2) performs a limiting and fixing operation on the sunroof glass (107) to facilitate the automobile sunroof durability test. Step 2: Before the vehicle sunroof is tested, the first servo motor (103) drives the transmission screw (104) to rotate, thereby driving the first slider (105) and the two sets of support frames (201) to move to the position of the test frame (106). When the support frames (201) reach the position of the test frame (106), the second servo motor (204) inputs current to drive the transmission screw (205) to rotate, thereby driving the two sets of second sliders (206) to move to the specified position. After the two sets of second sliders (206) move to the specified position, the limiting device (208) starts to supply current, thereby limiting the test frame (106), so that the test mechanism (3) drives the sunroof glass (107) to perform the test. When a set of limiting devices (208) is in an abnormal state for limiting the experimental frame (106), the experimental frame (106) drives the sensing plate (209) to contact the first pressure monitor (212), and the first pressure monitor (212) generates real-time first pressure data L and transmits it to the early warning system (4). The early warning system (4) determines the limiting state of the limiting device (208) for the experimental frame (106) according to the change of the real-time first pressure data L. When the limiting state of the experimental frame (106) is in an abnormal state, the early warning system (4) controls the first electric hydraulic column (211) to drive the sensing plate (209) to contact the surface of the experimental frame (106), thereby playing a role of temporary support and preventing the experimental frame (106) from being in a tilted state; Step 3: During operation, the second electric hydraulic column (301) and the third electric hydraulic column (303) input corresponding currents to drive the card slot plate (304) and the negative pressure adsorption device (306) to contact the surface of the skylight glass (107) to perform an adsorption and fixing operation. Under the action of the third electric hydraulic column (303), the skylight glass (107) is driven to perform a moving experimental operation. The electric control moving device drives the card slot plate (304) and the negative pressure adsorption device (306) to apply pressure to the skylight glass (107), so as to perform a pressure monitoring experiment on the skylight glass (107). The monitoring process During the process, the skylight glass (107) drives the negative pressure adsorption device (306) to contact the second pressure monitor (308) to generate second pressure data M. The early warning system (4) determines whether the skylight glass (107) is damaged according to the change of the second pressure data M. When the skylight glass (107) is subjected to the pressure test, the electric control moving device drives the protective net (310) to contact the bottom of the test frame (106) so as to recover the broken skylight glass (107) and avoid the broken skylight glass (107) from causing certain impact on the environment on site.
