[0027] It should be noted that for the device shown in Figs 1 and 2, the two lifting arms in the front of the vehicle are two lifting arms near the front wheels, and the two lifting arms in the rear of the vehicle are two lifting arms near the rear wheels. The lifting arms are bilaterally symmetrical. The floating mechanisms and the floating mechanisms are also disposed symmetrically. The device shown in Figs. 3 and 4 is merely a preferred embodiment. The quantities and setting manners of the adjustment structures 1 and the floating mechanisms 2 are not limited thereto. For example, the adjustment structures 1 are respectively disposed on the two lifting arms in the rear of the vehicle, and the floating mechanisms 2 are respectively disposed on the two lifting arms in the front of the vehicle.

[0028] In some examples, as shown in Fig. 3, the adjustment mechanism 1 comprises a driving portion 11, a linear movement portion 12, and a first bottom mounting plate 13, wherein the driving portion 11 and the first bottom mounting plate 13 are disposed on the lifting arms 3, and the linear movement portion 12 is disposed on the first bottom mounting plate 13 and is connected to the driving portion 11; the driving portion 11 is used to drive the linear movement portion 12 to move forward or backward in a linear direction; and The linear movement portion 12 is used to drive the corresponding support point to move forward or backward in the linear direction.

[0029] As shown in Fig. 4, the linear movement portion 12 comprises a driving plate 121, a linear guide rail 122, a linear slider 123, a lead screw nut 124, and a lead screw 125, wherein the driving plate 121 is connected to the linear slider 123 and the lead screw nut 124, the lead screw 125 and the linear guide rail 122 are disposed on the first bottom mounting plate 13, and the lead screw 125 is connected to the driving portion 11.

[0030] The driving portion 11 drives the lead screw 125 to rotate, the lead screw 125 pushes the lead screw nut 124 to move back and forth, and the lead screw nut 124 drives the driving plate 121 to move back and forth, so as to drive the corresponding support point of the vehicle to move back and forth. Preferably, the lead screw 125 and the driving portion 11 are connected to by means of a coupling 14, and the lead screw 125 is disposed on a corresponding bearing block 15 and is then mounted on the first bottom mounting plate 13.

[0031] During the position adjustment of the vehicle, the driving portion 11 drives the lead screw 125 to rotate, the lead screw 125 pushes the lead screw nut 124 to move back and forth, the lead screw nut 124 drives the driving plate 121 to move back and forth, and the linear slider 123 moves along the linear guide rail, so as to adjust the position of the vehicle in the X-axis direction.

[0032] The adjustment mechanism 1 further comprises a control module (not shown in the figure) for communicating with the driving portion 11 to output a corresponding position adjustment instruction to the driving portion 11.
the control module comprises: a photographing unit, a computing unit, and a fine adjustment unit, wherein the photographing unit is used to photograph a positioning hole of a vehicle body and a positioning pin of a battery swap trolley to obtain photographic data; the computing unit is used to compute a current position deviation of the vehicle relative to a preset position according to the photographic data, the preset position being a preset battery swap position where the vehicle should be located; and the fine adjustment unit is used to output a corresponding position adjustment instruction to the driving portion 11 according to the obtained position deviation of the vehicle.

[0033] The adjustment mechanism 1 shown in Fig. 1 and Fig. 2 is used to illustrate the adjustment process by example. The preset position is used as a reference, and it is assumed that two adjustment mechanisms 1 in the front of the vehicle are respectively a left-side adjustment mechanism and a right-side adjustment mechanism. The photographing unit photographs the vehicle body positioning hole and the positioning pin of the battery swap trolley to obtain photographic data. The computing unit computes the current position deviation of the vehicle with respect to the preset position according to the photographic data, and determines that the vehicle body inclines towards the left-side adjustment mechanism with respect to the preset position. The fine adjustment unit sends a forward-push instruction to a left-side driving portion, and at the same time sends a backward-push instruction to a right-side driving portion, such that the left-side driving portion uses a left-side lead screw nut to drive a left-side driving plate to move forward, and the right-side driving portion uses a right-side lead screw nut to drive a right-side driving plate to move backward. The left-side driving plate drives a left-side support point to move forward. The right-side driving plate drives a right-side support point to move backward. The floating mechanism 2 floats along with the vehicle in the horizontal plane, so as to enable the vehicle body to rotate to the right with respect to the X-axis direction, so as to align the position of the vehicle body. Similarly, if the position of the vehicle is slightly ahead or behind relative to the preset position in the X-axis direction, the leftside adjustment mechanism and the right-side adjustment mechanism are controlled to move forward or backward at the same time to adjust the position of the vehicle. This will be no longer described herein.

[0034] In some examples, the driving portion 11 comprises a servo motor.

[0035] As shown in Fig. 3, the floating mechanism 2 comprises a floating portion 21, a support portion 22, and a restoring portion 23, wherein the floating portion 21 is in rolling contact with the support portion 22 by means of universal balls 24, such that the floating portion 21 is supported by the support portion 22 to float in the horizontal plane relative to the support portion 22; The universal ball 24 can not only limit the degree of freedom of the floating portion 21 in a vertical direction, but also implement floating of the floating portion 21 in a horizontal direction; and The restoring portion 23 is connected to the floating portion 21 for restoring the floating portion 21.

[0036] As shown in Figs. 5 and 6, the floating portion 21 comprises a connecting post 211, and a first floating plate 212 and a second floating plate 213 which are respectively connected to two ends of the connecting post 211 and are parallel to each other. The connecting post 211 can limit the floating range of the floating portion 21 and limit the degree of freedom of the floating portion 21 in the vertical direction. Preferably, the connecting post 211 and the first floating plate 212 are of an integrated structure. The connecting post 211 and the second floating plate 213 are fixedly connected, such that the first floating plate 212 and the second floating plate 213 are also fixedly connected, such as being connected through a screw 214. The screw 214 passes through the second floating plate 213 and enters the connecting post 211 to fixedly connect the second floating plate 213 and the connecting post 211. The use of the screw 214 to connect the second floating plate 213 and the connecting post 211 is merely a preferred embodiment. Other method that can fixedly connect the two is also applicable.

[0037] The support portion 22 is provided with a through hole 221 for the connecting post 211 to pass through. The first floating plate 212 and the second floating plate 213 are respectively located outside the through hole 221 and is in rolling contact with the support portion 22 by means of the universal ball 24. A floating gap 25 is provided between the connecting post 211 and a through-hole wall 222. At least one of the first floating plate 212 and the second floating plate 213 is provided with the restoring portion 23. In some examples, the connecting post 211 is of a cylindrical structure.

[0038] The floating mechanism 2 further comprises a second bottom mounting plate 26, the support portion 22 is fixedly connected to the second bottom mounting plate 26, and one end of the restoring portion 23 is connected to the second bottom mounting plate 26, and the other end thereof is connected to the second floating plate 213. Preferably, three or more restoring portions 23 are disposed on the second floating plate 213 in a circumferential direction, and are uniformly disposed in the circumferential direction of the second floating plate 213. When the position of the vehicle body is adjusted, the adjustment mechanism 1 drives the vehicle body to move, and the vehicle body drives the first floating plate 212 to float. Because the first floating plate 212 is fixedly connected to the second floating plate 213, the second floating plate 213 also floats in the horizontal plane. In this case, the restoring portion 23 is stretched or compressed as the second floating plate 213 floats. After the vehicle body leaves the first floating plate 212, the floating mechanism 2 has no load. All the restoring portions 23 automatically restore, drive the second floating plate 213 to restore in the central position, and can ensure that the floating mechanism 2 has an amount of floating for repeatable positioning.

[0040] In some examples, the second floating plate 213 is respectively provided with a catching hole 28 at the front, rear, left, and right in the circumferential direction, and the second bottom mounting plate 26 is provided with four corresponding catching pins 27 in the circumferential direction of the second floating plate 213.

[0041] Preferably, the restoring portion 23 is a tension spring. The tension spring is merely a preferred embodiment, but the invention is not limited thereto. Other elastic part that can enable the first floating plate 212 and the second floating plate 213 to restore in the central position may be used herein. The parameters, such as the elasticity coefficient and the length of the tension spring, are set according to the factors such as the bearing capacity of the floating mechanism and the size of the floating mechanism 2.

[0042] The floating mechanism 2 further comprises a locking portion 29, which is disposed between the first floating plate 212 and the second bottom mounting plate 26 for tightly locking the floating mechanism 2.

[0043] In the embodiment shown in Figs. 5 and 6, the locking portion 29 comprises an electromagnetic brake attraction plate 291 and an attraction plate control portion 292. An upper surface of the electromagnetic brake attraction plate 291 is attracted to or released from the first floating plate 212. The second bottom mounting plate 26 is connected to the attraction plate control portion 292. The attraction plate control portion 292 is powered on or off to enable the electromagnetic brake attraction plate 291 to tightly attract or release the first floating plate 212, so as to lock or release the floating mechanism 2. The structure of the locking portion 29 mentioned above is merely a preferred embodiment, but the invention is not limited thereto. Other locking portions that can fasten the floating mechanism 2 after the position of the vehicle body is adjusted and render the floating portion 21 temporarily unmovable are all applicable.

[0044] By means of providing the floating mechanism 2, the number of driving mechanisms 1 can be reduced, the number of the driving portions 21 is thus reduced, the number of electric motors is reduced, and four-point synchronism and coordination are improved. The floating mechanism 2 has a large amount of floating, can bear a heavy load, is restorable, can be locked in position, and can be combined with the adjustment mechanism 1 to adjust the position of the vehicle so as to improve the positioning precision.

[0045] In the embodiment of the invention, all positions can be controlled by means of limit switches.

[0046] In some examples, a small support surface is further disposed on the driving plate 121 and the first floating plate 212. For example, a support circular surface 4 is configured to support the support points of the vehicle. As such, the contact area can be reduced, and the positioning precision can be improved.

[0047] The invention further provides a battery swap system comprising the foregoing vehicle positioning adjustment device. The foregoing vehicle positioning adjustment device is used to adjust a vehicle to an accurate battery swap position.

[0048] The embodiments of the invention provide a vehicle positioning adjustment device and a battery swap system comprising the vehicle positioning adjustment device. The device has a simple structure and is easy and convenient to operate. The device can precisely adjust an X-axis position of a vehicle and correct an oblique position of the vehicle body so as to implement automatic battery swap of the battery swap system.
