When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0056] Cotton pickers, silage machines, various harvesting machines, and various mining machinery need to be tested on the field after they come off the production line. Large agricultural machinery and mining machinery are huge in size, and the field running test requires a large area of ​​site. The running test of large machinery makes a lot of noise, causing serious noise pollution to surrounding companies. Some products will have grease spillage, causing site pollution. The field running test of large machinery will also cause damage to the road surface. Large machinery will also cause certain traffic obstructions during the running process, and the risk of causing traffic accidents is also relatively high.

[0057] In order to solve the technical problem that the existing sports car test occupies a large area of ​​the site, the present application proposes an in-situ sports car test equipment for a vehicle, including a basic platform, a rotating support roller group, a roller locking device and a traction limiting device; the rotating support roller group includes a plurality of roller bodies, which are rotatably arranged on the basic platform, and the roller bodies are used to support the wheel bodies of the test vehicle; the roller locking device is connected to each roller body, and the roller locking device is used to lock each roller body; the traction limiting device is arranged on the basic platform, and the output end of the traction limiting device is used to connect with the test vehicle, and the traction limiting device is configured to tow the test vehicle to limit the wheel body of the test vehicle from driving out of the rotating support roller group.

[0058] When using the in-situ sports car test equipment for the vehicle of the present application, firstly, each roller of the rotating support roller group is locked by the roller locking device to prevent the roller from rotating, so as to facilitate the test vehicle to drive onto the rotating support roller group. Then, the test vehicle is driven onto the rotating support roller group on the basic platform so that each wheel of the test vehicle is located on the rotating support roller group. Then, the test vehicle is towed by the traction limiting device to limit the movement of the test vehicle and prevent the wheel of the test vehicle from driving out of the rotating support roller group. Finally, each roller is unlocked by the roller locking device, and the test vehicle can perform the in-situ sports car test on the in-situ sports car test equipment for the vehicle of the present application. The rotating support roller group enables the rotation support of the equipment to be tested when it is driving in-situ at different speeds. The rotation support of the rotating support roller group ensures that the equipment to be tested can simulate driving in-situ at different speeds on the device. The test vehicle is towed by the traction limiting device to limit the movement of the test vehicle and prevent the wheel of the test vehicle from driving out of the rotating support roller group.

[0059] As a result, the on-site sports car test equipment for the vehicle of the present application does not require a large site, greatly reducing the site requirements, solving the technical problem of the large site area occupied by existing sports car tests, and avoiding damage to the road surface by the test vehicle. The on-site sports car test equipment for the vehicle of the present application is equipped with a closed factory building, which can effectively reduce the noise pollution caused by the sports car test.

[0060] The following specific embodiments are combined with the accompanying drawings to describe the technical solution of the application in detail. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

It should be noted that, in order to facilitate observation of the accompanying drawings, Figure 1 A lateral traction mechanism is omitted at the front wheel body.

[0062] In the embodiments of this application, refer to Figures 1 to 3 As shown, an embodiment of the present application provides an in-situ running car test equipment for a vehicle, comprising a basic platform 100, a rotating support roller group 200, a roller locking device 400 and a traction limiting device 500; the rotating support roller group 200 comprises a plurality of roller bodies 210, the roller bodies 210 are rotatably arranged on the basic platform 100, and the roller bodies 210 are used to support the wheel bodies 310 of the test vehicle 300; the roller locking device 400 is connected to each roller body 210, and the roller locking device 400 is used to lock each roller body 210; the traction limiting device 500 is arranged on the basic platform 100, and the output end of the traction limiting device 500 is used to connect with the test vehicle 300, and the traction limiting device 500 is configured to tow the test vehicle 300 to limit the wheel body 310 of the test vehicle 300 from driving out of the rotating support roller group 200.

[0063] A rotating support roller group 200 is arranged on the base platform 100 of the in-situ sports car test equipment of the vehicle of the present application. The rotating support roller group 200 is composed of a plurality of roller bodies 210. The roller bodies 210 are rotatably arranged on the base platform 100. The roller bodies 210 can be rotatably arranged on the base platform 100 through roller bearing seats 1800. The roller bodies 210 are used to support the wheel bodies 310 of the test vehicle 300. The rotating support roller group 200 enables the test vehicle 300 to be rotationally supported when traveling at different speeds in-situ. The rotating support of the rotating support roller group 200 ensures that the test vehicle 300 can simulate traveling in-situ at different speeds on the present application.

[0064] The roller locking device 400 is connected to each roller body 210, and the roller locking device 400 is used to lock each roller body 210. When the roller locking device 400 locks each roller body 210, the roller body 210 cannot rotate, which facilitates the test vehicle 300 to drive onto the rotating support roller group 200, and prevents the test vehicle 300 from slipping due to the rotation of the roller body 210, making it impossible for the test vehicle 300 to drive onto the rotating support roller group 200.

[0065] When using the in-situ sports car test equipment for vehicles of the present application, firstly, each roller body 210 of the rotating support roller group 200 is locked by the roller locking device 400 to prevent the roller body 210 from rotating, so as to facilitate the test vehicle 300 to drive onto the rotating support roller group 200, and then the test vehicle 300 is driven onto the rotating support roller group 200 on the base platform 100, so that each wheel body 310 of the test vehicle 300 is located on the rotating support roller group 200, and then the test vehicle 300 is towed by the traction limiting device 500 to limit the movement of the test vehicle 300 and prevent the wheel body 310 of the test vehicle 300 from driving out of the rotating support roller group 200. The roller group 200 is finally unlocked by the roller locking device 400, and the test vehicle 300 can perform an in-situ sports car test on the in-situ sports car test equipment of the vehicle of the present application. The rotating support roller group 200 allows the test vehicle 300 to be rotationally supported when it is traveling in-situ at different speeds. The rotating support of the rotating support roller group 200 ensures that the test vehicle 300 can simulate traveling in-situ at different speeds on the device. The test vehicle 300 is towed by the traction limiting device 500 to limit the movement of the test vehicle 300 and prevent the wheel body 310 of the test vehicle 300 from driving out of the rotating support roller group 200.

[0066] As a result, the on-site sports car test equipment for the vehicle of the present application does not require a large area of ​​site, greatly reducing the site demand, solving the technical problem of the large site area occupied by the existing sports car test, and avoiding the test vehicle 300 from damaging the road surface. The on-site sports car test equipment for the vehicle of the present application is equipped with a closed factory building, which can effectively reduce the noise pollution caused by the sports car test.

[0067] In another embodiment, referring to Figures 5 to 7 As shown, the roller locking device 400 includes at least one stick locking assembly 410, and the stick locking assembly 410 includes a guide rail 411, a sliding seat 412, a plurality of locking blocks 413 and a sliding drive member 414; the guide rail 411 is arranged on the base platform 100, the sliding seat 412 is slidably connected to the guide rail 411, a plurality of locking blocks 413 are arranged on the sliding seat 412, and the locking blocks 413 are arranged corresponding to the roller body 210, the locking blocks 413 are provided with grooves, and the roller body 210 is provided with bosses matching the grooves; the sliding drive member 414 is connected to the sliding seat 412, and the sliding drive member 414 is configured to drive the sliding seat 412 to move on the guide rail 411 so that the grooves of each locking block 413 correspond one by one to clamp the bosses of each roller body 210.

[0068] In this embodiment, the roller body 210 is locked or unlocked by at least one stick locking assembly 410, because the sliding seat 412 is slidably connected to the guide rail 411, and the sliding seat 412 can move on the guide rail 411 through the sliding driving member 414, and a plurality of locking blocks 413 are provided on the sliding seat 412, and the number of the locking blocks 413 is the same as the number of the roller body 210, and the locking blocks 413 are provided with grooves, and the roller body 210 is provided with a groove matching the groove. The sliding drive member 414 drives the sliding seat 412 to move on the guide rail 411, so that the grooves of each locking block 413 correspond to each other and clamp the bosses of each roller body 210, thereby locking each roller body 210. When unlocking is required, the sliding drive member 414 drives the sliding seat 412 to move in the opposite direction on the guide rail 411, so that the bosses of each roller body 210 are disengaged from the grooves of each locking block 413, thereby unlocking and each roller body 210 can rotate.

[0069] In other embodiments, flanges 600 are provided at both ends of the roller body 210, and bosses are provided on the flanges 600; there are two stick locking assemblies 410, and the stick locking assemblies 410 correspond one to one to the bosses.

[0070] Specifically, each locking block 413 of one stick locking assembly 410 is clamped one-to-one with the boss of the flange 600 at one end of each roller body 210 through a groove, and each locking block 413 of the other stick locking assembly 410 is clamped one-to-one with the boss of the flange 600 at the other end of each roller body 210 through a groove.

[0071] In this embodiment, flanges 600 are provided at both ends of the roller body 210, and bosses are provided on the flanges 600. The locking blocks 413 of one stick locking assembly 410 are clamped one-to-one with the bosses of the flange 600 at one end of each roller body 210 through grooves, thereby locking one end of each roller body 210. The locking blocks 413 of the other stick locking assembly 410 are clamped one-to-one with the bosses of the flange 600 at the other end of each roller body 210 through grooves, thereby locking each roller body 210. The locking of the other end of the roller body 210, that is, both ends of each roller body 210 are locked, so that each roller body 210 is locked more firmly to prevent each roller body 210 from loosening, and because a stick locking assembly 410 is provided at both ends of each roller body 210, each roller body 210 is subjected to uniform force when locked, thereby preventing the roller body 210 from deflecting or bending due to uneven force, thereby improving the stability of the rotating support roller group 200 and ensuring the accuracy of the test.

[0072] In one embodiment, referring to Figures 1 to 3 As shown, the traction limiting device 500 includes at least one transverse traction mechanism 510, the transverse traction mechanism 510 includes two transverse traction components, the transverse traction component includes a transverse drive component and a transverse traction rope 5111, the transverse drive component is arranged on the base platform 100, one end of the transverse traction rope 5111 is connected to the output end of the transverse drive component, and the other end of the transverse traction rope 5111 is connected to the wheel body 310 for corresponding rotation, and the transverse drive component is configured to tighten the transverse traction rope 5111 to limit the wheel body 310 from moving along the axis direction of the wheel body 310.

[0073] Specifically, the transverse traction rope 5111 of one transverse traction component of the transverse traction mechanism 510 is used to be rotatably connected to the wheel body 310 on the left side of the test vehicle 300 to limit the wheel body 310 on the left side of the test vehicle 300 from moving to the right; the transverse traction rope 5111 of another transverse traction component of the transverse traction mechanism 510 is used to be rotatably connected to the wheel body 310 on the opposite right side of the test vehicle 300 to limit the wheel body 310 on the right side of the test vehicle 300 from moving to the left.

[0074] In this embodiment, the lateral traction mechanism 510 is used to limit the left-right swing of the test vehicle 300. In order to adapt to different test vehicles to match the traction and ensure the stability and accuracy of the traction, the traction position is set on the wheel body 310 of the test vehicle 300 in this embodiment.
