[0036] The technical solution of the utility model is further described in conjunction with the following embodiments.
[0037] Example 1
[0038] A vehicle rolling device for testing a charging pile connector, such as Figures 2 to 4 As shown, a tire assembly 100, a load frame 200, a vertical moving assembly 300 for moving the tire assembly 100 up and down, a horizontal moving assembly 400 for driving the tire assembly 100 to move horizontally, and a main body 600 are provided. The tire assembly 100 is assembled with the load frame 200, the load frame 200 is slidably assembled with the vertical moving assembly 300, the vertical moving assembly 300 is slidably assembled with the horizontal moving assembly 400, and the horizontal moving assembly 400 is assembled with the main body 600.
[0039] It should be noted that the horizontal moving assembly 400 of the vehicle rolling device for testing the charging pile connector of the utility model is used to drive the tire assembly 100, the load frame 200 and the vertical moving assembly 300 to move forward and backward in the horizontal direction as a whole, thereby simulating the scene of the vehicle moving forward or backward. The vertical moving assembly 300 of the utility model is used to drive the tire assembly 100 and the load frame 200 to move vertically perpendicular to the horizontal direction as a whole. The vertical moving assembly 300 can simulate the up and down movement process caused by the bumps and vibrations caused by the vehicle rolling over foreign objects (such as the charging pile connector) during driving.
[0040] The vertical moving assembly 300 is provided with a pair of slide rails 310 and multiple pairs of sliders 320. The pair of slide rails 310 are respectively vertically assembled on the horizontal moving assembly 400, and the multiple pairs of sliders 320 are respectively fixed on the load frame 200, and the sliders 320 are evenly distributed on the slide rails 310 and slidably connected with the slide rails 310.
[0041] The horizontal moving assembly 400 is provided with a driving transmission part 410, a guide rail 420 and a guide wheel 430. The guide wheel 430 is assembled with the vertical moving assembly 300. The guide wheel 430 is rollingly connected with the guide rail 420. The guide rail 420 is fixedly assembled on the main body 600. The driving transmission part 410 is fixedly connected with the load frame 200.
[0042] The driving transmission part 410 is provided with a motor 411, an active ratchet 412, a transmission ratchet 413 and a chain 414. The motor 411 is fixedly assembled on the main body 600, and the transmission shaft of the motor 411 is transmission-connected with the active ratchet 412. The transmission ratchet 413 is rotatably assembled on the main body 600. The chain 414 is transmission-connected with the active ratchet 412 and the transmission ratchet 413 respectively, and the chain 414 is also fixedly connected to the load frame 200.
[0043] The guide wheel 430 is a conical guide wheel 430. Figure 5 The cross-sectional shape of the guide rail 420 is an isosceles triangle, as shown in FIG. Figure 6 shown.
[0044] It should be noted that the conical guide wheel 430 mentioned in the present invention is specifically a conical guide wheel 430 formed by the top surfaces of two truncated cones being attached to each other, as shown in the figure. The cross-sectional shape of the guide rail 420 is an isosceles triangle, so the conical guide wheel 430 is basically attached to the guide rail 420, thereby increasing the support area and meeting the new standard requirement of using an overall load of 11000N for testing.

The tire assembly 100 is located below the support plate 220. Figure 7 shown.
[0046] The number and weight of the weights 240 of the utility model can be adjusted according to test requirements.
[0047] In the vehicle rolling device for testing the charging pile connector of the utility model, the two ends of the rolling plate 500 are respectively fixedly connected to the main body 600.
[0048] Example 2
[0049] A vehicle rolling device for testing a charging pile connector, the other features of which are the same as those of Example 1, and further have the following features: a tire assembly 100 is provided with a wheel body 110 and a deviation correction and damping assembly 120 for offsetting deflection and damping when the wheel body 110 rotates, a rotation axis 111 of the tire passes through the deviation correction and damping assembly 120, and the deviation correction and damping assembly 120 is fixedly connected to a load frame 200, such as Figure 7 .
[0050] The deviation correction and damping assembly 120 is provided with a bearing seat 121 and a plurality of automatic centering mechanisms 122 for enabling the rotating shaft 111 to continue to rotate in the case of deviation. The plurality of automatic centering mechanisms 122 are respectively mounted inside the bearing seat 121, and the plurality of automatic centering mechanisms 122 are distributed at both ends of the bearing seat 121. One end of the rotating shaft 111 is sequentially mounted inside the plurality of automatic centering mechanisms 122 and protrudes from the bearing seat 121. The bearing seat 121 is fixedly connected to the load frame 200. Fig. 9 and Fig.10 shown.
[0051] Because the load-bearing capacity of the present invention can reach 11000N or even higher, and the test sample often causes the tire assembly 100 to bump and move up and down during the test, if ordinary linear bearings are used alone, the wheel body 110 is very likely to lock in actual use. The present invention connects the wheel body 110 and the load frame 200 through an automatic centering mechanism 122, and corrects the up and down movement during the shock absorption process of the vertical moving assembly 300, thereby maintaining the concentricity of the wheel body 110 during movement, and allowing the wheel body 110 to continue to rotate freely under heavy loads.
[0052] It should be noted that the function of the automatic self-aligning mechanism 122 is to offset the deflection and reduce shock when the wheel body 110 rotates, such as an automatic self-aligning bearing, etc. Mechanisms with such functions are common mechanisms in industrial production, and the automatic self-aligning mechanism 122 with such functions can all be used as the automatic self-aligning mechanism 122 of the utility model, and the structure and working principle of the automatic self-aligning mechanism 122 will not be described in detail here.
[0053] Compared with Example 1, the vehicle crushing device for testing the charging pile connector of this embodiment has higher operating stability, so that the vehicle crushing device for testing the charging pile connector of this embodiment better meets the standard requirements of load-bearing tests of 11000N or above.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
