A jack 208 is mounted on the longitudinal beam 206, and a support plate 2081 is mounted on the power end of the jack 208. A universal joint is positioned between the jack 208 and the support plate 2081. The vertical plate assembly includes a vertical plate 205 mounted on the crossbeam 204. Reinforcement ribs 2051 are mounted on the front and rear sides of the vertical plate 205. The vertical plate 205 is provided with threaded holes 2052.

The positioning reinforcement assembly 206 includes a reinforcement positioning rod 207 provided on one side of the longitudinal beam 206 , and a positioning pin 2071 is provided on the reinforcement positioning rod 207 .

[0029] In this embodiment, the mobile testing mechanism 3 includes a tailgate mounting and limiting seat 301 mounted on the support mechanism 2. A supporting platform 304 is mounted on the tailgate mounting and limiting seat 301. A connecting assembly is mounted above the supporting platform 304. First lifting hydraulic cylinders 305 are mounted on the front and rear sides of the supporting platform 304. A telescopic rod 308 is mounted on the supporting platform 304. A counterweight mounting plate 311 is mounted on the telescopic rod 308. A second connecting shaft 309 is disposed between the telescopic rod 308 and the supporting platform 304. Second lifting hydraulic cylinders 310 are mounted on both sides of the telescopic rod 308. A limiting assembly is mounted on the counterweight mounting plate 311. A counterweight block 312 made of a soft rubber material is mounted on the outer surface of the limiting assembly. A first connecting shaft 303 is disposed between the tailgate mounting and limiting seat 301 and the supporting platform 304. The connecting assembly includes a square block 306 mounted above the supporting platform 304. A connecting mounting plate 307 is mounted on the outer surface of the square block 306.

[0030] Working principle: When in use, first, according to the design parameters of the tailgate, start the jack 208 to push the support plate 2081 to adjust the bearing platform 304 to the required angle, and by adjusting the position of the longitudinal beam 206 on the vertical plate 205, the position of the jack 208 and the support plate 2081 can be adjusted, and the tailgate is placed on the bearing platform 304 through the square block 306 and the connecting mounting plate 307. Start the first lifting hydraulic cylinder 305 to push the bearing platform 304 and the telescopic rod 308 to extend and retract to a certain length, and then stop after extending to a certain length. Start the second lifting hydraulic cylinder 310 to drive the counterweight mounting plate 311 and the counterweight block 312 to extend and retract for a second time, and then lift the tailgate to the maximum height. The high limit position means that the tailgate is not compressed at this time. According to the center of gravity position and mass of the tailgate design, the telescopic length of the second lifting hydraulic cylinder 310 and the number and mass of the counterweight blocks 312 on the counterweight mounting plate 311 are adjusted to change the experimental weight. After adjustment, the counterweight mounting plate 311 and the counterweight blocks 312 can be extended and retracted through the operation of the second lifting hydraulic cylinder 310, and the jack 208 cooperates with the support plate 2081 to complete the action of the tailgate rising to open or falling to close, thereby completing the parameters of the entire tailgate. All can be achieved stepless speed regulation on the adjustable tailgate test bench of this device, so it can be applied to tailgates with different design parameters to simulate the opening and closing effects of the tailgate, and the control effect of the controller.
