[0002] In recent years, with the development of my country's automobile industry and the continuous updating of products, higher requirements have been put forward for the comfort of automobiles. Among them, the functional requirements for seat armrests are also getting higher and higher. In the durability test of the seat armrest mechanism, the armrest is required to be adjusted from the closed position to the use position, and then the specified load is applied to the use position, and finally adjusted to the closed position of the armrest. This is a cycle, which is run for the specified number of cycles and finally the relevant performance parameters are tested.

[0003] This test can only be conducted manually, that is, the test personnel adjust the seat and count manually, which not only has high labor intensity and is time-consuming for the test personnel, but also has low reliability of test parameters due to differences among different test personnel, and does not meet the test requirements. In this regard, Chinese patent No. CN207133037U discloses a durability test device for adjusting the armrest of a rear seat of an automobile, which is composed of a frame, a pressure mechanism, a pressure sensor, a rotating shaft seat, a rocker mechanism, a servo motor, a reducer, and an angle sensor; the pressure mechanism is mounted on a stand on the rear side of the frame and loads pressure downward, the pressure sensor is mounted on the pressure mechanism, the two rotating shaft seats are symmetrically mounted on the bottom frame on the left and right sides of the frame, the two sides of the rocker mechanism are mounted between the two rotating shaft seats through a rotating shaft, the angle sensor is mounted on the rotating shaft on one side, the servo motor and the reducer are coaxially mounted on the rotating shaft on the other side in sequence, and under the drive of the servo motor, the rotating shaft drives the rocker mechanism to swing up and down below the pressure mechanism.

[0004] The device is installed on the roller through the seat armrest, and the seat hinged to the seat armrest needs to be fixed and installed. The general method is to install and fix it through multiple bolts. This method is cumbersome to disassemble and assemble, and it is easy to cause wear to the seat mounting frame. For this reason, we propose a car rear armrest durability detection fixture to solve the above problem. Utility Model Content
