Because steel has high strength, rigidity and durability, it can withstand large loads and working pressures, thereby improving the strength of car window lifters. In car window lifter manufacturers, when mass-producing car window lifters, it is necessary to sample several car window lifters for durability testing to determine whether the produced car window lifters are qualified, so as to evaluate the reliability, durability, safety performance and service life of the car window lifters during use, thereby ensuring the factory quality of the car window lifters. Durability testing equipment is needed when conducting durability tests on car window lifters.

[0032] In this embodiment, limiting grooves are provided on the inner walls on both sides of the mounting groove 7, and limiting blocks are fixedly installed on both sides of the slide 8. The two limiting blocks are respectively slidably installed in the corresponding limiting grooves, and are used to limit the sliding stroke of the slide 8 and to guide the sliding direction of the slide 8, so that the slide 8 maintains vertical sliding in the mounting groove 7.

[0033] In this embodiment, a transverse guide rod 21 is fixedly installed in the drive box 17, and the drive seat 19 is slidably sleeved on the transverse guide rod 21 to guide the moving direction of the drive seat 19 so that the drive seat 19 moves smoothly in the drive box 17.

[0036] In this embodiment, the length of the impact column 29 is greater than the length of the clamping seat 9, so as to ensure that the automobile window lifter can effectively perform a collision test with the impact column 29.

[0037] In the present embodiment, it should be noted that the vibration motor 14, the electric telescopic rod 18, the first electric hydraulic cylinder 27 and the second electric hydraulic cylinder 28 can all be purchased on the market. The vibration motor 14, the electric telescopic rod 18, the first electric hydraulic cylinder 27 and the second electric hydraulic cylinder 28 are equipped with a power supply, and their line connection and control methods are mature technologies in this field, so they are not described in detail herein. In addition, a test fixture (not shown herein) for controlling the power-on operation of the automobile window lifter is also installed on the test bench 1. By connecting the automobile window lifter and the test fixture with a wire, the operation of the automobile window lifter can be controlled.

[0038] Through the above structure, the automobile window lifter durability testing device provided by the present application can test the durability of the automobile window lifter when it is subjected to vibration force, can test the durability of the automobile window lifter when it is subjected to bumps, and can also test the durability of the automobile window lifter when it is subjected to collision force, thereby achieving a more realistic dynamic simulation test of the durability of the automobile window lifter and improving the accuracy of the test results. During the specific operation, the automobile window lifter is vertically placed on the clamping seat 9, and the bottom of the automobile window lifter is located between the multiple abutment plates 12 in the clamping groove 10, and then the multiple rotary handles 13 are rotated clockwise in sequence, and the rotary handles 13 drive the screw rod 11 and the abutment plate 12 to rotate clockwise, so that the abutment plate 1 2 gradually moves in the direction close to the automobile window lifter. When the plurality of abutment plates 12 are tightly against the bottom outer wall of the automobile window lifter, the automobile window lifter is firmly and stably clamped and fixed on the clamping seat 9. Then, the automobile window lifter can be electrically connected to the test fixture using a wire, and the automobile window lifter can be controlled to be powered on and run. Then, the vibration motor 14 is turned on and runs. By utilizing the elastic force of the plurality of springs 15 and cooperating with the vibration force generated when the vibration motor 14 runs, the slide seat 8 can be controlled to drive the clamping mechanism and the firmly clamped automobile window lifter to vibrate, so as to simulate the automobile window lifter being subjected to vibration force during driving, and to test its durability when the automobile window lifter is subjected to vibration force. The electric telescopic rod 18 can be turned on to extend and retract reciprocatingly for many times, thereby controlling the driving seat 19 and the rack 20 to reciprocate horizontally, and the rack 20 will drive the gear 16 and the rotating shaft 4 to reciprocate, thereby making the connecting seat 5, the sliding seat 8, the vibration mechanism, the clamping mechanism and the clamped automobile window lifter swing left and right with the rotating shaft 4 as the center, so as to simulate the bumping of the automobile window lifter during the driving of the automobile on the uneven road, and to test the durability of the automobile window lifter under the condition that the automobile is bumped, and by controlling the operation of the two first electric hydraulic cylinders 27, the corresponding rectangular lifting seat 25, the second electric hydraulic cylinder 28 and the impact column 29 can be pushed to move vertically, and the two impact columns 29 can be moved When the window lifter reaches a suitable height, the two first electric hydraulic cylinders 27 are stopped, and the two second electric hydraulic cylinders 28 are controlled to extend, so that the two impact columns 29 can be controlled to move horizontally and linearly, so that the automobile window lifter swinging left and right can collide with the two impact columns 29, and the two second electric hydraulic cylinders 28 are stopped. At this time, the situation in which the automobile window lifter is subjected to a collision force can be simulated, and its durability performance can be tested when the automobile window lifter is subjected to a collision force. After the test is completed, the electric telescopic rod 18 is stopped, the vibration motor 14 is stopped, and the two first electric hydraulic cylinders 27 and the two second electric hydraulic cylinders 28 are controlled to retract and return to their positions, and then the plurality of rotary handles 13 are rotated counterclockwise in sequence to release the clamping fixation of the automobile window lifter.Then you can remove the tested car window regulator and continue to perform durability testing on another car window regulator according to the above steps.
