As the automotive industry rapidly develops towards lightweight, electrified and intelligent driving, the market has placed higher requirements on the accuracy, durability and dynamic response characteristics of shock absorbers.

[0003] The detection device commonly used in the market currently uses a motor to drive a rotating disk to rotate, and a connecting rod is eccentrically rotated on the rotating disk. The rotation of the rotating disk drives the connecting rod to move up and down, thereby repeatedly pulling the automobile shock absorber, thereby testing the service life of the automobile shock absorber; However, in the prior art, the pulling amplitude of the device that repeatedly pulls in the above manner is consistent, resulting in the detection device using a constant-amplitude pulling method to simulate the repeated compression and extension process of the shock absorber. However, this simplified simulation method cannot accurately reflect the complex road conditions and variable vibration frequencies encountered by the car during actual driving, resulting in the inability to simulate real working conditions and the limitation of the detection data.

[0024] In a further embodiment, referring to Figure 1 - Figure 10 , a stamping assembly 8 is fitted and installed at the bottom of the installation box 101. The stamping assembly 8 includes a mounting plate 801 and a connecting frame 806. A plurality of connecting frames 806 are evenly distributed on the rear side of the bottom surface of the installation box 101. An installation cylinder 804 is fixedly provided on the connecting frame 806. A first connecting cylinder 805 is installed on the top surface of the installation cylinder 804. The first connecting cylinder 805 penetrates through the bottom of the installation box 101 and extends into the inner cavity of the installation box 101. A plugging column 803 is slidably installed in the installation cylinder 804. The top of the plugging column 803 is connected with a rubber column 815.

One ends of the plurality of second springs 802 away from the installation cylinder 804 are connected with the mounting plate 801, and the mounting plate 801 is connected with the plugging column 803; A plurality of arc-shaped frames 808 are evenly distributed on the top surface of the first connecting cylinder 805. A connecting frame 806 is provided between the top surfaces of the plurality of arc-shaped frames 808. A third spring 809 is installed on the bottom surface of the connecting frame 806. One side of the third spring 809 away from the circular plate 816 is connected with a first sealing bead 810; An air inlet cylinder 807 is installed on the side wall of the installation cylinder 804.

The rubber post 815 and the plug post 803 will rapidly pressurize the gas in the mounting cylinder 804 and press the first sealing bead 810 upward, so that the gas in the mounting cylinder 804 rapidly fills the space between the mounting box 101 and the sliding plate 109. Subsequently, the sliding plate 109, the support column 108, and the bearing plate 107 are rapidly lifted, thereby lifting the stones on the top of the bearing plate 107 upward to collide with the vehicle shock absorber. During the reset process, with the pulling of the plug post 803 and the rubber post 815, the air pressure in the mounting cylinder 804 will decrease.

[0025] In a further embodiment, referring to Figure 1 、 Figure 2 and Figure 9 On the outer walls on the left and right sides of the detection box 1, limiting components 3 are respectively installed.

The telescopic end of the cylinder 301 penetrates through the side wall of the detection box 1 and extends into the inner cavity of the detection box 1. An installation frame 302 is installed on the telescopic end of the cylinder 301. On the inner side wall of the inner cavity of the installation frame 302, a first spring 303 is symmetrically installed. On the front and rear inner walls of the installation frame 302, limiting blocks 304 are respectively installed; A support block 305 is slidably installed in the installation frame 302. The side wall of the support block 305 is connected to the first spring 303. On the front and rear sides of the support block 305, sliding grooves 306 are respectively opened. The limiting blocks 304 slide in the inner cavities of the sliding grooves 306. The lower part of the support block 305 is designed in an arc shape, and the top surface of the support block 305 is designed in a flat shape; Among them, the design of the sliding grooves 306 and the limiting blocks 304 prevents the support block 305 from detaching from the installation frame 302. The bottom surface of the support block 305 is designed in an arc shape, and the end surface is designed in a flat shape. Thus, when the mounting plate 801 moves from bottom to top, it is convenient for the mounting plate 801 to break through the support block 305. After the mounting plate 801 breaks through the support block 305, it can be supported by the support block 305.

[0026] In a further embodiment, referring to Figure 1 - Figure 2 The lifting component 2 includes a limiting rod 201 and a hydraulic telescopic rod 202. The limiting rods 201 symmetrically penetrate through the top surface of the detection box 1 in a sliding manner. Between the ends of the two limiting rods 201 located in the inner cavity of the detection box 1, an installation frame one 204 is installed. A bolt one 203 is installed on the bottom surface of the installation frame one 204. A hydraulic telescopic rod 202 is installed on the top surface of the detection box 1. The telescopic end of the hydraulic telescopic rod 202 is connected to the installation frame one 204; Among them, the hydraulic telescopic rod 202 drives the first mounting bracket 204 and the first bolt 203 to move up and down to adapt to shock absorbers of different lengths for automobiles.

[0027] The working principle of the present invention is as follows: When the device is in use, first, the electrical equipment in the device is powered on. Subsequently, the shock absorber for the automobile is placed between the first mounting bracket 204 and the second mounting bracket 12, and the first bolt 203 and the second bolt 14 are used to position the shock absorber for the automobile. Subsequently, stones are laid on the surface of the bearing plate 107. Then, the closing door 5 is closed. By using the bearing plate 107, the closing door 5, the observation glass 6, and the detection box 1, a sealed space is formed. Then, the first motor 403 is started to drive the second connecting shaft 406, the first rotating disc 407, and the second rotating disc 410 to rotate. Since the positions of the first rotating disc 407 and the second rotating disc 410 are relatively stationary, the distance from the sliding rod 15 inside the moving groove 408 and the arc-shaped groove 411 to the center position of the first rotating disc 407 or the second rotating disc 410 is constant. Therefore, when the first rotating disc 407 and the second rotating disc 410 rotate, the sliding rod 15 drives the push rod 11 to swing up and down with the same amplitude. During the use process, the third motor 413 is started to drive the worm 414, the third connecting cylinder 416, and the second rotating disc 410 to rotate. When the second rotating disc 410 rotates, the arc-shaped groove 411 will squeeze the sliding rod 15 and drive the sliding rod 15 to move in the moving groove 408, thereby adjusting the up-and-down swing amplitude of the push rod 11, achieving the effect that the up-and-down pulling amplitude of the push rod 11 can be changed during the detection process, and thus accurately simulating and restoring complex road conditions. During the rotation of the first rotating disc 407, the moving groove 408 abuts against the mounting plate 801 and moves it upward. During the rapid upward movement of the mounting plate 801, the mounting plate 801 squeezes the plug post 803 and the rubber post 815 to move upward rapidly. The rubber post 815 and the plug post 803 will quickly pressurize the gas in the mounting cylinder 804 and press the first sealing bead 810 upward, so that the gas in the mounting cylinder 804 quickly fills the space between the mounting box 101 and the sliding plate 109. Subsequently, the sliding plate 109, the support column 108, and the bearing plate 107 are quickly lifted, so that the stones on the top of the bearing plate 107 are lifted upward and collide with the shock absorber for the automobile, achieving the effect that the scenario of stones colliding with the shock absorber for the automobile can be simulated during the detection process. This irregular vibration can better evaluate the performance of the shock absorber under various working conditions and provide more accurate data support for improvement and optimization. During the upward movement of the mounting plate 801, the mounting plate 801 will squeeze the support block 305 and squeeze the support block 305 into the mounting frame 302. When the mounting plate 801 moves above the support block 305, under the action of the first spring 303, the support block 305 will reset, and the top surface of the support block 305 will support the mounting plate 801 to prevent the mounting plate 801 from resetting under the action of the second spring 802. Subsequently, when the sliding plate 109 moves upward to the position of the pressure relief groove 16, the airflow between the sliding plate 109 and the mounting box 101 will be discharged along the pressure relief groove 16. At this time, under the action of the fifth spring 104, the sliding plate 109 will drive the support column 108 and the receiving plate 107 to reset. When the reset is completed, the cylinder 301 is started to drive the mounting frame 302 and the support block 305 to quickly contract and extend. At this time, under the action of the second spring 802, the mounting plate 801 and the insertion column 803 will quickly reset. During the reset process, as the insertion column 803 and the rubber column 815 are pulled, the air pressure in the mounting cylinder 804 will become smaller. Under the action of the atmospheric pressure, the second sealing bead 817 will move downward to allow air to enter the mounting cylinder 804; Repeat the above operations, so that after the receiving plate 107, the support column 108, and the sliding plate 109 rise, the mounting plate 801 is limited at the highest position by the receiving assembly 10, giving the receiving plate 107, the support column 108, and the sliding plate 109 time to reset, so as to ensure the amplitude of the next lift of the stones by the receiving plate 107. A stable detection rhythm helps to reduce error accumulation, achieving the effect of ensuring that each shock absorber can be evenly and accurately tested.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
