Description

Technical Field

[0001] The utility model relates to the technical field of automobile testing, in particular to a fixture for testing an automobile tailgate. Background Art

[0002] Automobile testing is an inspection to determine the technical condition or working ability of an automobile. During the use of an automobile, as the service time extends (or the driving mileage increases), its parts gradually wear, corrode, deform, age, and the lubricating oil deteriorates, etc., resulting in an increase in the clearance of the mating pair, causing looseness in movement, vibration, rattling, air leakage, water leakage, oil leakage, etc., and causing a decline in the technical performance of the automobile. The core of automobile maintenance work (or automobile maintenance work) is to "maintain" the good condition of the automobile technical condition. After the automobile is processed and assembled, it is necessary to conduct a tensile test on the automobile tailgate to judge the stability after the tailgate is closed.

[0003] In the prior art, a test bench for an electric strut of an automobile tailgate with the application number 202020729873.7 is used to test the electric strut. The test bench for the electric strut of the automobile tailgate includes: a main frame, including a lock catch for connecting to a tailgate lock; a movable frame, one end of which is hinged to the main frame, and the other end is connected to the tailgate lock facing the main frame, and the electric strut is connected between the main frame and the movable frame to push and pull the movable frame to rotate relative to the main frame; a top support mechanism, arranged on the main frame, for supporting the movable frame. The above-mentioned test bench for the electric strut of the automobile tailgate is provided with a top support mechanism on the main frame. When the tailgate lock is unlocked and the lock tongue of the tailgate lock retracts, the top support mechanism extends to support the movable frame so that the tailgate lock is disengaged from the lock catch. When the lock tongue is reset, it will no longer be connected to the lock catch of the main frame. In this way, the electric strut can pull the movable frame to rotate away from the main frame, simulating the working condition of the electric strut of the automobile tailgate. However, it is not convenient to detect the magnitude of the tensile force borne by the test automobile tailgate when it is closed, and the tailgate suddenly opens during driving, affecting the driving safety.
