[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a motor vehicle safety performance testing platform.

[0026] The utility model provides Figure 1-3 A motor vehicle safety performance test bench shown in the figure comprises a test bench 1 and a groove opened on the top of the test bench 1, a plurality of support plates 2 are contacted with the inner wall of the groove, two symmetrically arranged driving rollers 3 are rotatably arranged between two adjacent support plates 2, a first guide block 4 and a second guide block 5 are respectively fixedly arranged on the side away from each other of the two adjacent support plates 2, a plurality of guide holes are opened on the side wall of the groove, the first guide block 4 and the second guide block 5 are both slidably arranged in the guide holes, the longitudinal sections of the first guide block 4 and the second guide block 5 are both rectangular, a motor 6 is fixedly arranged on the outer wall of the first guide block 4, the output end of the motor 6 passes through the first guide block 4 and is fixedly connected to the driving roller 3, and a telescopic plate 17 is fixedly arranged between the plurality of support plates 2;

[0027] The side walls of the two second guide blocks 5 are fixed with connecting blocks 7, and a lateral adjustment mechanism is provided between two adjacent connecting blocks 7. The lateral adjustment mechanism includes two symmetrically arranged connecting plates 8, and the two connecting plates 8 are fixedly connected to the outer wall of the inspection table 1. Adjusting screws 9 are rotatably provided inside the two connecting plates 8. The adjusting screws 9 are threaded in the connecting blocks 7, and a rotating block 10 is fixedly provided at one end of the two adjusting screws 9 close to each other.

[0028] Before conducting a safety performance test on a motor vehicle, the distance between the front and rear wheels of the motor vehicle to be tested is determined, and the two adjusting screws 9 are rotated by the rotating block 10, so that the adjusting screws 9 drive the two connecting blocks 7 to move laterally during the rotation. At this time, under the sliding cooperation of the first guide block 4, the second guide block 5 and the guide hole, the distance between the driving rollers 3 on both sides can be adjusted, and when the distance between the driving rollers 3 on both sides is the same as the distance between the front and rear wheels of the motor vehicle, the position of the rotating block 10 is fixed, and then the motor vehicle is moved onto the multiple driving rollers 3 and supported by the telescopic plate 17, and then the motor 6 on either side is started, so that the motor 6 drives the driving roller 3 to rotate, and the wheels of the motor vehicle begin to rotate, so that the braking performance of the motor vehicle can be effectively tested.

[0029] In order to be able to fix the positions of the adjusting screw 9 and the driving roller 3 before and after the adjusting screw 9 is rotated, as shown in FIG. Figure 1-3 As shown, a connecting ring 11 is sleeved on the outer side of the adjusting screw 9, and the connecting ring 11 is fixedly connected to the inspection table 1. A positioning bolt 12 is passed through the internal thread of the connecting ring 11, and a plurality of thread grooves 13 are arranged symmetrically around the side wall of the rotating block 10 and are plugged into the positioning bolt 12.

[0030] Before rotating the adjusting screw 9, the positioning bolt 12 can be pulled out from the thread groove 13, and the rotating block 10 can be started to be rotated, so that the rotating block 10 drives the adjusting screw 9 to rotate. When the position of the driving roller 3 is determined, the positioning bolt 12 can be inserted into the thread groove 13 again to determine the position of the adjusting screw 9 relative to the driving roller 3.

[0031] In order to enable the motor vehicle to be stably moved onto the inspection platform 1, Figure 1-2 As shown, a rotation groove is provided at the upper ends of both sides of the inspection table 1, a fixing rod 14 is fixed in the rotation groove, a side plate 15 is rotatably sleeved on the rod wall of the fixing rod 14, a fixing bolt 16 is threadedly passed through between the inspection table 1 and the side plate 15, and a plurality of threaded holes for connecting with the fixing bolts 16 are provided on the side wall of the inspection table 1.

[0032] When inspecting a motor vehicle, the motor vehicle can be stably moved onto the inspection platform 1 by the side panels 15 on both sides. Then, with the support of the fixing rods 14, the side panels 15 can be rotated to a vertical position, and the fixing bolts 16 can be inserted into the upper threaded holes to determine the position of the side panels 15. The motor vehicle is limited during the inspection process to avoid deviation of the motor vehicle as much as possible.
