[0028] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0029] like Figure 1-3As shown, an electric transport vehicle simulation detection device includes a positioning mechanism 1 and a lifting mechanism 2.

[0030] The electric transport vehicle includes a frame, a driving wheel group located on the frame, and a battery pack. The driving wheel group includes a front wheel group and a rear wheel group. In order to simulate the electric transport vehicle passing through an uneven road section, the front wheel group and the rear wheel group need to be randomly lifted.

[0031] In this embodiment, the positioning mechanism 1 includes a support assembly 11, and the support assembly 11 includes a support bar. The support platform 111 is used to place the electric transport vehicle. The lifting mechanism 2 includes a front top assembly 21, a first rear top assembly 22 and a drive assembly 24. The front top assembly 21 and the first rear top assembly 22 are both arranged on the support platform 111 so as to be liftable through the drive assembly 24. The front top assembly 21 can abut against the front wheel group and be used to drive the wheel body in the front wheel group to perform lifting and lowering movements. The first rear top assembly 22 can abut against the rear wheel group and be used to drive the wheel body in the rear wheel group to perform lifting and lowering movements. The wheel bodies in the front wheel group and the rear wheel group are randomly driven to be lifted to simulate the uneven road surface, and the service life of the electric transport vehicle can be judged according to the duration that the electric transport vehicle can last on the road.

[0032] In order to increase the applicability of the simulation detection equipment, it also includes a second rear top assembly 23 and a third rear top assembly. The front top assembly 21, the first rear top assembly 22, the second rear top assembly 23 and the third rear top assembly are arranged on the support platform 111 along the length direction of the support platform 111, the second rear top assembly 23 is located between the front top assembly 21 and the first rear top assembly 22, and the third rear top assembly is located between the first rear top assembly 22 and the second rear top assembly 23. That is, when the front wheel assembly remains stationary, if a different vehicle model is replaced, its rear wheel assembly can be placed on the first rear top assembly 22 or the second rear top assembly 23 or the third rear top assembly according to the actual position, thereby increasing its applicability. At the same time, a fourth rear top assembly and a fifth rear top assembly, etc. can also be added, which can be set according to actual needs.

[0033] Specifically, the front wheel group includes a driving wheel and auxiliary wheels on both sides of the driving wheel. The driving wheel is installed at the bottom of the front end of the frame, and the two auxiliary wheels are symmetrically arranged on both sides of the driving wheel. The driving wheel is used to drive the overall displacement of the electric transport vehicle, and the two auxiliary wheels are used to prevent it from tipping over. Usually, the height of the auxiliary wheels is higher than that of the driving wheels, and when passing through uneven roads, the auxiliary wheels will also abut against the protrusions. The rear wheel group includes two driven wheels, and the two driven wheels are installed on both sides of the bottom of the rear end of the frame to support the rear end of the frame.

[0034] Correspondingly, the front top assembly 21 includes at least three front top blocks 211 arranged on the support platform 111 at intervals along the width direction of the support platform 111, each front top block 211 corresponds to a driving wheel or an auxiliary wheel, and the driving assembly 24 includes multiple lifting cylinders 241, each front top block 211 is raised and lowered on the support platform 111 by a lifting cylinder 241, and any front top block 211 can be abutted against the driving wheel or the auxiliary wheel. During the detection process, the multiple lifting cylinders 241 move randomly and randomly drive the three front top blocks 211 to rise or fall individually, simulating uneven road conditions.

[0035] Similarly, the first rear top assembly 22 includes at least two first rear top blocks 221 arranged on the support platform 111 at intervals along the width direction of the support platform 111. Each first rear top block 221 is liftably disposed on the support platform 111 by a lifting cylinder 241, and the first rear top block 221 can abut against the bottom of the driven wheel. When the rear wheel group is placed on the first rear top assembly 22, the two driven wheels can be driven to rise and fall individually by the two first rear top blocks 221 to simulate the rear wheel group passing through an uneven road surface.

[0036] Similarly, the second rear top assembly 23 includes at least two second rear top blocks 231 arranged on the support platform 111 at intervals along the width direction of the support platform 111. Each second rear top block 231 is liftably set on the support platform 111 by a lifting cylinder 241, and the second rear top block 231 can abut against the bottom of the driven wheel. When the rear wheel group is placed on the second rear top assembly 23, the two second rear top blocks 231 can independently drive the two driven wheels to perform random lifting and lowering movements.

[0037] In order to prevent the frame from tipping over, the positioning mechanism 1 also includes a first anti-tipping assembly 12. The first anti-tipping assembly 12 includes two groups of first guide wheels 121 symmetrically arranged on the top of the support platform 111. The two groups of first guide wheels 121 can respectively abut against two symmetrical sides of the frame. When the frame tips over, the first guide wheels 121 can abut against one side of the frame to limit its further tipping over and improve safety performance.

[0038] At the same time, the electric transport vehicle also includes a body, which is installed on the frame. In order to prevent the body from tipping over, the positioning mechanism 1 also includes a second anti-tipping assembly 13. The second anti-tipping assembly 13 includes two groups of second guide wheels 131 symmetrically arranged on the top of the support platform 111. The two groups of second guide wheels 131 can respectively abut against the two symmetrical sides of the body, and the height of the second guide wheel 131 is higher than the height of the first guide wheel 121. Similarly, when the body tips over, the second guide wheel 131 can abut against one side of the body to prevent it from continuing to tilt, that is, limiting the anti-rollover effect is performed simultaneously up and down.

[0039] In order to prevent the electric transport vehicle from detaching from the front top assembly 21 and the first rear top assembly 22 or the second rear top assembly 23, the positioning mechanism 1 also includes a limit assembly 14, which includes a plurality of limit wheels 141 arranged at the rear of the support platform 111. The limit wheels 141 can abut against the rear end of the vehicle body to limit the overall movement of the electric transport vehicle along the length direction of the support platform 111.
