The force-bearing mechanism 2 includes a counterweight 21, a rubber protective plate 22 is provided on one side of the counterweight 21 and is connected by a snap-fit, limit plates 23 are provided at both ends of the counterweight 21 and are connected by screws, two sliding mechanisms 24 are provided between the two limit plates 23, a transmission rack 25 is fixedly provided on the other side of the counterweight 21, and limit slide bars 26 are provided on both sides of the transmission rack 25, and the limit slide bars 26 are connected to the counterweight 21 by screws.
[0022] The collection mechanism 3 includes two mounting blocks 31, which are connected to the mounting plate 1 by screws. A motor 32 is embedded inside one of the mounting blocks 31 and connected by screws. A transmission gear 33 is fixed to the output end of the motor 32. The transmission gear 33 is located between the two mounting blocks 31. The transmission gear 33 is fastened to the output end of the motor 32 by screws. The output end of the motor 32 is connected to the other mounting block 31 by a rotating shaft. The transmission rack 25 is meshed with the transmission gear 33. When the transmission gear 33 rotates, it drives the motor 32 to generate electricity in reverse. The time when the motor output current reaches a fixed power is detected by an external device to calculate and compare the kinetic energy.
[0023] The two mounting blocks 31 are also provided with rubber protective plates 22 on their sides and connected by buckles. Slide sleeves 34 are fixedly provided on the inner sides of the two mounting blocks 31. The limiting slide bar 26 is located on the inner side of the sliding sleeve 34. A top plate 35 is provided above the two mounting blocks 31. The top plate 35 and the two mounting blocks 31 are connected by screws. A limiting block 36 is fixedly provided below the top plate 35. The limiting block 36 is located between the two mounting blocks 31. The limiting block 36 is slidably connected to the transmission gear 33. The rubber protective plate 22 can prevent the force-bearing mechanism 2 from directly hitting the collection mechanism 3 and causing damage. The top plate 35 and the limiting block 36 can limit the height position of the transmission rack 25.
[0024] The sliding mechanism 24 includes two pulley mounting blocks 27 arranged opposite to each other. The two pulley mounting blocks 27 are respectively located at the upper and lower sides of the mounting plate 1. A plurality of arc grooves 271 are arranged on the inner sides of the two pulley mounting blocks 27. A sliding roller 272 is arranged in the arc groove 271. The sliding roller 272 is connected to the pulley mounting block 27 through a rotating shaft. A rotating shaft stopper 273 is arranged at both ends of the sliding roller 272. The rotating shaft stopper 273 is connected to the pulley mounting block 27 through screws. The sliding roller 272 is in contact with the mounting plate 1.

A limit plate 23 is located between the guide plate 11 and the mounting plate 1 to facilitate limiting the displacement direction of the limit plate 23.
[0026] Working principle: When the utility model is in use, the test vehicle hits the counterweight block, causing the counterweight block to slide rapidly along the direction of the mounting plate, and the sliding connection with the mounting plate through the sliding roller reduces the friction, thereby preventing the speed of the force-bearing mechanism from decreasing and affecting the kinetic energy collection effect. The counterweight block pushes the transmission rack to move rapidly and drives the meshing gear to rotate. When the transmission gear rotates, it drives the motor to generate electricity in the reverse direction. The time it takes for the motor output current to reach a fixed power is detected by an external device to calculate and compare the kinetic energy.
