The first support plate 14 and the second support plate 15 are both slidably connected to the base 11 along the Y direction, the first support plate 14 is arranged outside the first movable member 12, and the second support plate 15 is arranged outside the second movable member 13.

[0038] The vehicle is driven onto the positioning platform, and the left and right wheels are supported on the first support plate 14 and the second support plate 15 respectively. The distances between the two movable parts and the two adjacent wheels are different, and there is a deviation. Exemplarily, the distance between the first movable part 12 and the left wheel is smaller than the distance between the second movable part 13 and the right wheel. The driving device drives the first movable part 12 and / or the second movable part 13 to move. Through the connecting rod device, the first movable part 12 drives the second movable part 13 to move in the opposite direction synchronously, and / or the second movable part 13 drives the first movable part 12 to move in the opposite direction synchronously, and the first movable part 12 and the second movable part 13 move in the Y direction The distance is the same. The first movable part 12 contacts the left wheel first, and the driving device continues to drive the first movable part 12 and / or the second movable part 13 to move. The first movable part 12 applies force to the left wheel, and the left wheel drives the first support plate 14 to slide, and the second movable part 13 moves in the opposite direction synchronously for the same distance until the second movable part 13 contacts the right wheel. When the initial positions of the first movable member 12 and the second movable member 13 are symmetrically arranged at the Y-direction center of the positioning platform, the first movable member 12 and the second movable member 13 move synchronously in opposite directions. During the movement, the first movable member 12 and the second movable member 13 remain symmetrically arranged at the Y-direction center of the positioning platform. When the first movable member 12 contacts the left wheel and the second movable member 13 contacts the right wheel, the left wheel and the right wheel are symmetrically arranged at the Y-direction center of the positioning platform, thereby realizing the centering adjustment of the vehicle body. The adjustment process is simple and fast, and the centering position is accurate.

[0039] In one embodiment, Figure 4 As shown, the first movable member 12 and the second movable member 13 each include a top plate 121 and two side plates 122 respectively connected to the two ends of the top plate 121 in the X direction, each of the side plates 122 has a flange, and a first slider 123 is provided at the bottom of each flange; the first support plate 14 and the second support plate 15 are respectively arranged below the top plate 121 of the first movable member 12 and the second movable member 13, and are located between the two side plates 122; the second slider 141 is provided at the two ends of the X direction of the first support plate 14 and the second support plate 15; the base 11 is provided with a first slide rail 111 and a second slide rail 112 extending along the Y direction and respectively adapted to the first slider 123 and the second slider 141, the first slider 123 is slidably connected to the first slide rail 111, and the second slider 141 is slidably connected to the second slide rail 112, so that the first movable member 12 and the second movable member 13 are slidably connected to the first slide rail 111, and the first support plate 14 and the second support plate 15 are slidably connected to the second slide rail 112.

[0040] The first slide rail 111 and the second slide rail 112 can be set as slide rails with the same specifications, and the first slider 123 and the second slider 141 can be set as the same slider. In order to support stability, a slide rail can be provided with multiple matching sliders. In order to prevent each slider from sliding out of the slide rail, a blocking component can be set at the end of each slide rail, for example, a step structure or a blocking block can be set at the base 11. The output end of the driving device can be connected to the flange of the first movable member 12 or the second movable member 13, and the driving device pushes the flange to push the first movable member 12 and the second movable member 13 to move. The first movable member 12 and the second movable member 13 then push the first support plate 14 and the second support plate 15 to move by pushing the wheel. The friction is small during movement, the sliding is smooth, and the driving force required is small. In order to prevent damage to the wheel, a cylindrical push rod 124 can be set on the outside of the top plate 121, and the push rod 124 contacts the wheel. In order to reduce weight and reduce the demand for driving force, the top plate 121, the first support plate 14 and the second support plate 15 can be provided with a hollow tube support extending along the X direction or the Y direction at the bottom of the flat structure, and the second slider 141 can be provided at the bottom of the hollow tube.

[0041] In one embodiment, reference Figure 2 and Figure 3 As shown, the connecting rod device includes a first connecting rod 171, a second connecting rod 172, a third connecting rod 173 and a first shaft 174, the two ends of the first connecting rod 171 are respectively hinged to one end of the first movable member 12 and one end of the second connecting rod 172, the two ends of the third connecting rod 173 are respectively hinged to one end of the second movable member 13 and the other end of the second connecting rod 172; the first shaft 174 is fixedly connected to the base 11, and the middle part of the second connecting rod 172 is rotatably connected to the first shaft 174; the first connecting rod 171 and the third connecting rod 173 are symmetrically arranged on the first shaft 174.

[0042] When the first movable member 12 moves to the left by a distance L, the first connecting rod 171 is pulled to move accordingly, and the end of the first connecting rod 171 connected to the first movable member 12 moves to the left by a distance L, and the first connecting rod 171 pulls the second connecting rod 172 to rotate around the first axis 174, and the second connecting rod 172 pushes the end of the third connecting rod 173 connected to the second movable member 13 to move to the right by a distance L, and the third connecting rod 173 pushes the second movable member 13 to move to the right by a distance L, then the connecting rod device drives the first movable member 12 and the second movable member 13 to move synchronously by the same distance in the opposite direction along the Y direction. The driving device and the connecting rod device are arranged between the first movable member 12 and the second movable member 13, and a cover plate can be arranged above the driving device and the connecting rod device for protection, and at the same time, the outer surface of the positioning platform can be made flat.

[0043] Preferably, the driving device includes two driving components, and the output ends of the two driving components are arranged opposite to each other and are respectively connected to the first movable member 12 and the second movable member 13. One driving component pushes the first movable member 12 to move to the left, and at the same time, the first movable member 12 pushes the second movable member 13 to move to the right through the connecting rod device; the other driving component pushes the second movable member 13 to move to the right, and at the same time, the second movable member 13 pushes the first movable member 12 to move to the left through the connecting rod device. The two driving components jointly drive the first movable member 12 and the second movable member 13 to move synchronously in opposite directions, which can provide a greater driving force for the first movable member 12 and the second movable member 13, and the driving force applied to the first movable member 12 and the second movable member 13 is more balanced.

[0044] The driving component can be connected to the first movable member 12 and the second movable member 13 through an articulated seat to achieve a flexible connection and protect the driving component. The driving component can use a cylinder 16, a linear motor, etc. The pressure of the cylinder 16 and the power of the linear motor can be set as needed, so that the driving component can push the wheel to make the corresponding support plate slide along the base 11 without damaging the wheel. For example, when the pressure of the cylinder 16 is set to 6-7 bar, the maximum load weight can reach 6.0T.

[0045] The positioning platform includes a front centering mechanism 101 and a rear centering mechanism 102. The front centering mechanism 101 is arranged at the front of the positioning platform, and the rear centering mechanism 102 is arranged at the rear of the positioning platform. The Y-direction center line of the first movable part 12 and the second movable part 13 of the front centering mechanism 101 is collinear with the Y-direction center line of the first movable part 12 and the second movable part 13 of the rear centering mechanism 102.

[0046] The front centering mechanism 101 and the rear centering mechanism 102 adjust the centering of the front wheels and the rear wheels of the vehicle respectively. The first movable member 12 and the second movable member 13 of the front centering mechanism 101 move synchronously in opposite directions to contact the left front wheel and the right front wheel respectively. The first movable member 12 and the second movable member 13 of the rear centering mechanism 102 move synchronously in opposite directions to contact the left rear wheel and the right rear wheel respectively. The Y-direction distance between the left front wheel and the right front wheel and the Y-direction center line of the first movable member 12 and the second movable member 13 of the front centering mechanism 101 is the same, and the Y-direction distance between the left rear wheel and the right rear wheel and the Y-direction center line of the first movable member 12 and the second movable member 13 of the rear centering mechanism 102 is the same. The Y-direction distances of the center lines are the same, the Y-direction center lines of the first movable part 12 and the second movable part 13 of the front centering mechanism 101 are collinear with the Y-direction center lines of the first movable part 12 and the second movable part 13 of the rear centering mechanism 102, then the Y-direction center lines of the first movable part 12 and the second movable part 13 of the front centering mechanism 101, the Y-direction center lines of the first movable part 12 and the second movable part 13 of the rear centering mechanism 102, the Y-direction center lines of the left front wheel and the right front wheel and the Y-direction center lines of the left rear wheel and the right rear wheel are collinear, thereby realizing rapid centering and positioning of each wheel of the vehicle, that is, realizing rapid centering and positioning of the vehicle body.

[0047] The positioning platform has a certain height, and there is a certain distance between the front centering mechanism 101 and the rear centering mechanism 102. In order to facilitate the vehicle to drive onto the positioning platform, an intermediate platform 200 is arranged between the front centering mechanism 101 and the rear centering mechanism 102, and a tail platform 300 and a ramp platform 400 are arranged in sequence at the end of the rear centering mechanism 102 away from the intermediate platform 200. The ramp platform 400 has an inclination angle of about 5-15° with the ground, and the vehicle can easily drive onto the positioning platform. The vehicle passes through the ramp platform 400, the tail platform 300, the rear centering mechanism 102, and the intermediate platform 200 in sequence and then enters the front centering mechanism 101.

[0048] In one embodiment, the first support plate 14 and the second support plate 15 of the front centering mechanism 101 are both provided with two positioning rods 142 arranged in parallel along the Y direction, and the two positioning rods 142 form a positioning groove, which can limit the front wheels of the vehicle. The two positioning rods 142 of the two support plates extend along the same straight line respectively. When the two front wheels of the vehicle are simultaneously stuck in the positioning groove, it indicates that the vehicle is in place in the X direction, which can improve the positioning accuracy of the vehicle in the X direction. The cross section of the positioning rod 142 can be set to a triangle, an inverted V shape, etc., which is conducive to the wheel falling into the positioning groove for limiting. Of course, the cross section of the positioning rod 142 can also be set to a circle, a semicircle, etc., which can position the front wheels of the vehicle, and is not limited here.

[0049] In one embodiment, the length of the first support plate 14 and the second support plate 15 of the rear centering mechanism 102 in the X direction is greater than the length of the first support plate 14 and the second support plate 15 of the front centering mechanism 101 in the X direction. In the X direction, the rear wheels of the vehicle can be parked at different positions of the first support plate 14 and the second support plate 15, which can adapt to vehicles with different wheelbases.

[0050] In one embodiment, the positioning platform includes a plurality of guide rods 21 arranged at both ends of the positioning platform in the Y direction. Each guide rod 21 can guide when the vehicle enters the positioning platform, limit the direction of the vehicle entering, reduce the distance between the wheel and the first movable member 12 and the second movable member 13, and shorten the centering adjustment time. Specifically, the guide rods 21 arranged at both ends of the centering mechanism can be fixedly connected to the base 11 through a fixed plate 22, and the first support plate 14 and the second support plate 15 are respectively located below the two fixed plates 22. When the first support plate 14 and the second support plate 15 move, they can move below the fixed plate 22 to avoid interference. The guide rods 21 arranged on the middle platform 200, the tail platform 300 and the ramp platform 400 can be fixedly arranged on each platform. The guide rods 21 arranged on the outside of the centering mechanism, the middle platform 200 and the tail platform 300 can extend in the X direction in a colinear manner, and the guide rods 21 arranged on the ramp platform 400 can extend in a trumpet shape to facilitate the vehicle to enter the positioning platform. In order to facilitate the vehicle to drive roughly in a straight line from the rear centering mechanism 102 to the front centering mechanism 101, a guide rod 21 may be provided on the inner side of the middle platform 200 to further limit the forward direction of the vehicle.
