The two rear wheel lifting mechanisms 24 are respectively slidably disposed on the guide rails 110 on the top of the two first movable bases 12. The two driving members 23 are respectively disposed on the two second movable bases 22 and are used to drive the rear wheel lifting mechanisms 24 to move along the guide rails 110. The two rear wheel brackets 25 are respectively disposed on the opposite inner side of the two rear wheel lifting mechanisms 24 and can move up and down under the drive of the rear wheel lifting mechanisms 24.

[0039] For ease of understanding and explanation, an XY rectangular coordinate system is established in the figure, where the X-axis is the first direction, which is the width direction of the vehicle; and the Y-axis is the second direction, which is the length direction of the vehicle.

[0040] In this embodiment, the vehicle lift slides two rear wheel lifting mechanisms 24 onto guide rails 110 on the top of two second movable bases 22, and drives the rear wheel lifting mechanisms 24 to move along the guide rails 110 via a drive member 23, thereby adjusting the distance between the two rear wheel lifting mechanisms 24 and the two front wheel lifting mechanisms 13 in the second direction to accommodate vehicles with different wheelbases.

[0041] In use, the distance between the two rear wheel lifting mechanisms 24 and the two front wheel lifting mechanisms 13 in the second direction is first adjusted according to the wheelbase of the vehicle to be lifted, then the two front wheel lifting mechanisms 13 are moved in opposite directions on the two sets of first ground rails 11, and the two rear wheel lifting mechanisms 24 are moved in opposite directions on the two sets of second ground rails 21, leaving an area for the vehicle to enter, then the vehicle is driven into the area between the two front wheel brackets 14 and the two rear wheel brackets 25, then the two front wheel lifting mechanisms 13 are moved relative to each other, and the two front wheel brackets 14 are inserted under the two front wheels respectively, at the same time, the two rear wheel lifting mechanisms 24 are moved relative to each other, and the two rear wheel brackets 25 are inserted under the two rear wheels respectively, and the two front wheel lifting mechanisms 13 and the two rear wheel lifting mechanisms 24 are controlled to act simultaneously, and the vehicle is lifted to a certain height by the front wheel brackets 14 and the rear wheel brackets 25. The use of the vehicle lifting machine can lift vehicles of different wheelbases and track widths, and has a wide range of applications.

[0042] In an embodiment, as shown in Figures 1-4 The first moving base 12 and the second moving base 22 are the same in structure, each including a seat body 100 and a walking mechanism 200 arranged at the bottom of the seat body 100. The walking mechanism 200 includes a walking motor (not shown in the figure) arranged on the seat body 100, a walking wheel (not shown in the figure) connected to the output shaft of the walking motor, and a guide wheel (not shown in the figure) arranged on the seat body 100. The walking wheel is in contact with the ground, and the guide wheel is rolling arranged on the first ground rail 11 / second ground rail 21.

[0043] Each set of first ground rails 11 and each set of second ground rails 21 has two parallel ground rails, and the guide wheel has two rows, which are rolling arranged on the two ground rails respectively.

[0044] The working principle of the walking mechanism 200 is as follows: the walking motor outputs power to the walking wheel, which rolls on the ground to drive the seat body 100 to move along the ground rail. The walking wheel is used for guiding.

[0045] In an embodiment, as shown in Figures 1-4 The front wheel lifting mechanism 13 and the rear wheel lifting mechanism 24 are the same in structure, each including a frame body 300 and an oil cylinder (located inside the frame body 300, not shown in the figure) arranged on the frame body 300. The cylinder body of the oil cylinder is fixed to the upper end of the frame body 300, the piston rod of the oil cylinder is vertically downward, and the front wheel bracket 14 / rear wheel bracket 25 is fixedly connected with the piston rod of the oil cylinder.

[0046] The oil cylinder is vertically downward arranged on the frame body 300, so that the front wheel bracket 14 / rear wheel bracket 25 can be lowered to be close to the ground, and can be better sent under the tire.

[0047] Specifically, the lower end of the frame 300 in the front wheel lifting mechanism 13 is fixed on the top of the first moving base 12, and the lower end of the frame 300 in the rear wheel lifting mechanism 24 is slidably arranged on the guide rail 110 on the top of the second moving base 22 through a sliding block.

[0048] Further, to improve the stability of the lifting of the front wheel bracket 14 / rear wheel bracket 25, a vertical guide rail can be arranged on the inner side of the frame 300, and a guide block slidably connected with the guide rail can be fixed on the front wheel bracket 14 / rear wheel bracket 25.

[0049] In an embodiment, as shown in Figures 1-5 the front wheel bracket 14 and the rear wheel bracket 25 are identical in structure, and each includes a mounting plate 400 and two bracket arms 500 fixed on the mounting plate 400 and arranged in the second direction, the two bracket arms 500 being capable of being inserted into the front and rear sides below the tire and supporting the tire.

[0050] Specifically, the side of the mounting plate 400 on the front wheel bracket 14 away from the two bracket arms 500 is connected with the lifting end of the front wheel lifting mechanism 13, and the side of the mounting plate 400 on the rear wheel bracket 25 away from the two bracket arms 500 is connected with the lifting end of the rear wheel lifting mechanism 24.

[0051] It can be understood that the distance between the two bracket arms 500 in the second direction is greater than the radius of the tire and less than the diameter of the tire, so as to ensure that the two bracket arms 500 can be inserted into the front and rear sides below the tire and support the tire.

[0052] Further, the opposite inner sides of the two bracket arms 500 are each provided with an upwardly inclined slope, which can increase the contact area with the tire and improve the stability of the tire on the two bracket arms 500.

[0053] In an embodiment, as shown in Figure 4 the top of the second moving base 22 is fixed with two guide rails 110 side by side, and the bottom of the rear wheel lifting mechanism 24 is fixed with two rows of sliding blocks (not shown in the figure), and the two rows of sliding blocks are slidably arranged on the two guide rails 110, respectively. By this arrangement, the stability of the movement of the rear wheel lifting mechanism 24 on the second moving base 22 is improved.

[0054] In an embodiment, as shown in Figures 3-4 the driving member 23 includes a driving oil cylinder, which is located at one end of the guide rail 110 in the length direction, and the axial direction of the driving oil cylinder is parallel to the length direction of the guide rail 110, the cylinder body of the driving oil cylinder is arranged on the top of the second moving base 22 through a mounting seat, the piston rod of the driving oil cylinder is connected with the lower end of the rear wheel lifting mechanism 24 through a hinged seat, and the driving oil cylinder adjusts the position of the rear wheel lifting mechanism 24 on the second moving base 22 by controlling the forward and backward extension of the piston rod.

[0055] It can be understood that in other embodiments, the driving member 23 can also be an electric cylinder, a pneumatic cylinder or other linear driving member 23.

[0056] Further, the two driving members 23 act synchronously to improve the adjustment efficiency.

[0057] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be considered within the scope of the present disclosure.

[0058] The above embodiments only express several implementation manners of the present application, and the description is specific and detailed, but it shall not be understood as a limitation on the scope of the application. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
