[0028] Reference Figure 1 As shown, the utility model provides a technical solution: an electric drive bridge test bench stand device, including a table plate 2, a plurality of support legs 1 are fixedly installed on the lower surface of the table plate 2, an electric drive bridge body 3 is detachably installed on the upper surface of the table plate 2, a covering structure 4 is provided on the surface of the table plate 2, and a rotating structure 5 is provided on the lower surface of the table plate 2.

[0029] The specific configuration and function of the capping structure 4 and the rotating structure 5 will be described in detail below.

[0030] Reference Figure 1-Figure 3As shown, in this embodiment, the cover structure 4 includes a connecting frame 403 fixedly connected to the surface of the platform 2. A slat 402 is slidably connected to the interior of the connecting frame 403. Two limit bars 405 are slidably connected to the interior of the slat 402. The lower ends of the two limit bars 405 are fixedly connected to an acrylic cover 401. The provision of the cover structure 4, by flexibly covering the electric drive bridge body 3, not only reduces the noise during the operation of the electric drive bridge body 3, but also allows personnel to observe the operating status of the electric drive bridge body 3 from the surface of the acrylic cover 401, thereby improving the performance of the electric drive bridge test bench device to a certain extent. The side walls of the slat 402 are evenly arranged with a plurality of sockets 408. A positioning block 407 is fixedly connected to the surface of the connecting frame 403. A latch 409 is slidably connected to the interior of the positioning block 407. The size of the latch 409 matches the size of the socket 408. Release latch 409 and insert it into the corresponding socket 408 on slat 402 to lock the rear acrylic cover 401. A stopper 410 is fixedly attached to the sidewall of latch 409. A spring 411 is sheathed on the surface of latch 409, with its ends fixedly connected to stopper 410 and positioning block 407, respectively. The spring 411's elastic force between stopper 410 and positioning block 407 forces latch 409 into the inner side of socket 408, enhancing the stability of locking the rear slat 402. Screw 406 is internally threaded and connected to the interior of acrylic cover 401. Rotating screw 406 drives acrylic cover 401 downward. A sealing gasket 404 is glued to the lower end of acrylic cover 401. During the downward movement of the acrylic cover 401 , the sealing gasket 404 is pushed to closely adhere to the surface of the table plate 2 , thereby further improving the tightness of the acrylic cover 401 covering the surface of the table plate 2 .

[0031] Reference Figure 1-Figure 2 and Figure 4As shown, the rotating structure 5 specifically includes a connecting post 51 fixedly connected to the lower surface of the platform 2. A limiting post 53 is slidably connected to the interior of the connecting post 51. A positioning plate 54 is fixedly connected to the lower end of the limiting post 53. A chassis 52 is rotatably mounted on the lower surface of the positioning plate 54. A fixing block 57 is fixedly connected to the side wall of the connecting post 51. A screw 55 is threadedly connected to the interior of the fixing block 57. The screw 55 is rotatably connected to the interior of the positioning plate 54. Rotating the screw 55 drives the positioning plate 54 to move. The limiting post 53 slides within the connecting post 51, limiting the movement direction of the chassis 52. Once the chassis 52 is positioned against the ground and the multiple support legs 1 are lifted, the platform 2 can be rotated on the ground, facilitating adjustment of the display angle of the electric drive axle test bench. A circular rubber ring 56 is bonded to the lower surface of the chassis 52. By providing the rubber ring 56 , the friction between the chassis 52 and the ground is increased, thereby improving the stability of the rotation of the electric drive axle test bench device.

[0032] Working principle: before testing the electric drive bridge body 3, pull the latch 409 first. At this time, the acrylic cover 401 will fall under its own gravity. At this time, the preliminary covering work of the electric drive bridge body 3 above the platform 2 can be achieved. Release the latch 409 and insert the latch 409 into the inner side of the corresponding hole 408 on the slat 402 to lock the acrylic cover 401 after covering. The latch 409 will be inserted into the inner side of the hole 408 by the elastic force of the spring 411 between the stopper 410 and the positioning block 407, thereby improving the stability of locking the slat 402 after movement. At this time, rotate the screw rod 406, and the screw rod 406 will drive the acrylic cover 401 to continue to move downward. The setting of the limit bar 405 plays a role in limiting the moving direction of the acrylic cover 401. During the downward movement, the acrylic cover 401 will push the sealing gasket 404 to fit tightly against the platform. 2, thereby further improving the tightness of the acrylic cover 401 covering the surface of the platform 2. At this time, during the inspection of the electric drive bridge body 3, not only the noise during the operation of the electric drive bridge body 3 is reduced, but also personnel can approach the surface of the acrylic cover 401 to observe the operating status of the electric drive bridge body 3, thereby further improving the test effect of the electric drive bridge body 3. After the test, the acrylic cover 401 can be flexibly lifted and supported, which is convenient for the subsequent disassembly and assembly of the stopped electric drive bridge body 3. By setting the covering structure 4 and flexibly covering the electric drive bridge body 3, not only the noise during the operation of the electric drive bridge body 3 is reduced, but also personnel can approach the surface of the acrylic cover 401 to observe the operating status of the electric drive bridge body 3, which improves the performance of the electric drive bridge test bench device to a certain extent.

[0033] When it is necessary to adjust the display angle of the electric drive bridge test bench device, first rotate the screw 55, and the screw 55 will drive the positioning plate 54 to move, wherein the limit column 53 slides inside the connecting column 51 to limit the moving direction of the chassis 52. Until the chassis 52 moves to a position close to the ground surface and the multiple support legs 1 are lifted, the table 2 can be rotated on the ground, thereby facilitating the adjustment of the display angle of the electric drive bridge test bench device. By providing the rubber ring 56, the friction between the chassis 52 and the ground is increased, and the stability of the rotation of the electric drive bridge test bench device is improved. By providing the rotating structure 5, the flexible twisting of the electric drive bridge test bench device after lifting is facilitated, and the multi-angle display of the electric drive bridge test bench device is facilitated, which further improves the performance of the electric drive bridge test bench device.
