The sliding grooves can be kidney-shaped holes, the number of the sliding grooves corresponds to the number of the pressing pieces 31, and when only one pressing piece 31 is arranged on the first pressing rod 32 or the second pressing rod 33 respectively, only one sliding groove is arranged on the first pressing rod 32 or the second pressing rod 33 respectively; when the first pressing rod 32 or the second pressing rod 33 is provided with two pressing members 31, the first pressing rod 32 or the second pressing rod 33 is provided with two sliding grooves, and the two sliding grooves are arranged in front of and behind each other. Of course, a plurality of pressing members 31 may share a single sliding groove.

Specifically, the pressing member 31 includes a pressing head 311, a pressing rod 312, an upper fastening member 313, and a lower fastening member 314, the pressing head 311 being for contact pressing with the pedal 53; the pressing rod 312 is used for adjusting the height of the pressing head 311; the upper fastening member 313 and the lower fastening member 314 serve to fix the pressing rod 312. When the device is installed, the pressing rod 312 passes through the fixing hole 34 or the sliding groove in a manner that the pressing head 311 faces downwards, then the height of the pressing rod 312 in the fixing hole 34 or the sliding groove is adjusted, the pressing depth is controlled, the position of the pressing piece 31 is fixed by the upper fastening piece 313, and finally the pressing rod 312 is locked by the lower fastening piece 314. The pressing rod 312 can be a bolt, the upper fastening piece 313 and the lower fastening piece 314 are nuts, and standard pieces are adopted, so that the cost can be greatly reduced, and the height adjustment of the pressing head 311 is facilitated. Preferably, the upper fastening member 313 can employ two nuts, the purpose of which is: the two nuts are adopted to have the functions of stopping and preventing looseness, and the nuts below can be prevented from loosening by utilizing the nuts above, so that the pressing force of the pressing rod is prevented from changing in the long-time detection process. The pressing head 311 can be made of soft material such as a silica gel sleeve or a cloth sleeve, and is sleeved on one end of the bolt, so that the surface of the pedal 53 is prevented from being damaged when the pressing head 311 contacts with the pedal 53.

The pressing assembly 3 can be driven by an electric motor to approach the balance vehicle 5, and can also be driven by a manual motor.

The second pressing rod 33 is connected to the bracket 1 in the same manner.

Because the pressing component 3 is rotatably connected with the bracket 1, under the condition of no power source, the pressing component presses the pedal 53 of the balance car 5 by means of the self weight, the balance car 5 may float up and down in the test process, and in order to reduce the weight of the whole test device and facilitate the movement of the pressing component 3, the weight of the pressing component 3 is not too large, and the pressing component 3 cannot press the balance car 5 or the pedal 53 thereon easily affected by the balance car 5. Therefore, it is necessary to provide the supporting member 4 so that the pressing member 3 is fixed at a set position and the pressing member 31 can continuously press the balance car 5 or the pedal 53 thereon. The supporting component 4 can be a motor, and is connected with the rotating shaft 36 of the pressing component 3 to keep the pressing component 3 at a fixed angle; alternatively, the support assembly 4 may be a mechanical structure, and the pressing assembly 3 is locked by a latch or a snap-fit structure to continuously press the pedal 53. In a specific embodiment, the supporting component 4 is located at the rear end of the pressing component 3, and is close to the rotating structure, at this time, the supporting component 4 may be a rotating rod (not shown) fixed on the cross frame 14 of the stand 1, one end of the rotating rod is rotatably connected with the cross frame 14, the other end of the rotating rod is detachably and fixedly connected with the first pressing rod 32 or the second pressing rod 33, the rear end of the first pressing rod 32 or the second pressing rod 33 is provided with a plurality of adjusting holes, during testing, the pressing component 3 presses on the pedal 53 of the balance car 5, and the rotating rod is rotated to fix the fastener at one end of the rotating rod with one of the adjusting holes, so as to fix the angle of the pressing component 3.

In another embodiment, as shown in fig. 5, the support member 4 is located at the front end of the pressing member 3, away from the rotating structure. At this time, the pressing assembly 3 includes a front cross bar 371; the supporting component 4 comprises a supporting rod 41 and an adjusting head 42, the adjusting head 42 is movably sleeved on one end of the supporting rod 41, and the other end of the supporting rod 41 is rotatably connected with the bracket 1; the front cross bar 371 is provided with an adjusting groove 372, the adjusting groove 372 is an open groove, and the length is larger than the diameter of the supporting rod 41, so that the supporting rod 41 can be still clamped in the adjusting groove 372 even if the pressing component 3 rotates for a certain angle; when the pressing assembly 3 is at the set position, the supporting rod 41 is inserted into the adjusting groove 372, and the adjusting head 42 is located above the adjusting groove 372 and applies a downward force to the pressing assembly 3.

Concretely, adjust first 42 and bracing piece 41 threaded connection, can reciprocate on bracing piece 41, after bracing piece 41 inserts the adjustment groove 372 after rotatory, adjust first 42 butt on the exterior structure of adjustment groove 372, through adjusting the upper and lower position of adjusting first 42, adjust the pivoted range from top to bottom of subassembly 3 of exerting pressure, thereby adjust the dynamics of pressing balance car 5, because subassembly 3 of exerting pressure is rotatory on support 1, so the whole function that also has some 5 gradients of regulation balance car of subassembly 3 of exerting pressure, can use with the cooperation of pressing 31 under the pressing of regulation head 42, reach the regulating action.
