[0031] Wherein, the lifting mechanism 20 includes a rectangular cylinder 201, a second hinge 202 and a first hydraulic push rod 203, the inner wall of the rectangular cylinder 201 is attached to the surface of the support plate 4, the bottom of the rectangular cylinder 201 is fixedly connected with the upper surface of the second hinge 202, the bottom of the second hinge 202 is fixedly connected with the upper surface of the first hydraulic push rod 203, the bottom of the first hydraulic push rod 203 is fixedly connected with the upper surface of the bottom plate 1.

[0033] It needs to be explained that through the cooperation of the annular groove 10 and the circular ring 11, the second threaded cylinder 12 cannot move left and right on the rotating shaft 9, the spring 18 makes the hemispherical block 14 and the arc-shaped groove 13 in close contact, and through the cooperation of the second rectangular hole 16 and the connecting column 17, the rotating shaft 9 can drive the hollow circular plate 15 to rotate, when the hollow circular plate 15 rotates, through the cooperation of the hemispherical block 14 and the arc-shaped groove 13, the second threaded cylinder 12 can rotate with the hollow circular plate 15, and through the cooperation of the second threaded cylinder 12 and the first threaded cylinder 7, the L-shaped clamping wheel rod 6 can move left or right, when the L-shaped clamping wheel rod 6 on one side is in contact with the wheel, since the L-shaped clamping wheel rod 6 cannot continue to move, the rotating shaft 9 will make the hemispherical block 14 slide out of the arc-shaped groove 13, and the second threaded cylinder 12 will not rotate any more, at the same time, the rotating shaft 9 continues to rotate, which makes the L-shaped clamping wheel rod 6 on the other side continue to move to the side close to the wheel, until the L-shaped clamping wheel rod 6 on the other side also comes into contact with the wheel, when the four L-shaped clamping wheel rods 6 are in contact with the corresponding wheels, through the L-shaped clamping wheel rod 6, the support plate 4 can be inclined without causing the vehicle to roll over.
[0034] Through the cooperation of the support column 2, the first hinge 3, the rectangular cylinder 201 and the second hinge 202, when the first hydraulic push rod 203 is elongated, the support plate 4 will rotate counterclockwise, when the first hydraulic push rod 203 is shortened, the support plate 4 will rotate clockwise, through the triangular cushion block 21, the vehicle can be more easily driven onto the support plate 4.
[0035] As shown in Figures 1 to 12 The upper surface of the support plate 4 is fixedly connected with a second U-shaped plate 24, the left and right sides of the inner wall of the second U-shaped plate 24 are fixedly connected with cylinders 25, the surface of the cylinder 25 is rotatably connected with a hollow block 26, the back surface of the hollow block 26 and the upper surface of the support plate 4 are fixedly connected with L-shaped elastic sheets 27, the upper surface of the hollow block 26 is fixedly connected with a stand 28, the upper surface of the stand 28 is fixedly connected with a vertical plate 29, and the front surface of the vertical plate 29 is fixedly connected with a signboard 30.
[0036] It needs to be explained that the stand 28, the vertical plate 29 and the signboard 30 are made of light plastic, the elastic force of the L-shaped elastic sheet 27 is greater than the weight sum of the stand 28, the vertical plate 29 and the signboard 30, through the L-shaped elastic sheet 27, the vertical plate 29 can maintain a vertical state when not impacted, when the vehicle is reversed onto the support plate 4, by observing the size of the signboard 30 in the rearview mirror, it can be directly judged whether the wheels are aligned with the L-shaped clamping wheel rod 6, thereby enabling the user to quickly and directly judge whether the wheels are aligned with the L-shaped clamping wheel rod 6 when parking the vehicle on the support plate 4, at the same time, when the vehicle collides with the vertical plate 29, since the vertical plate 29 can rotate around the cylinder 25 after being impacted, the vertical plate 29 and the vehicle will not be damaged due to the impact.
[0037] The working principle of the utility model is as follows: first, the vehicle is inverted on the support plate 4 by reversing, then, the size of the indicator 30 in the rearview mirror is observed, whether the wheel is aligned with the L-shaped wheel clamping rod 6 can be judged directly, when the wheel is aligned with the L-shaped wheel clamping rod 6, the vehicle is stopped, the hand brake is pulled up, then, the driving motor 8 drives the rotating shaft 9 to rotate, at this time, since the L-shaped wheel clamping rod 6 does not contact the wheel, the resistance of the second threaded cylinder 12 is small when rotating, the hollow circular plate 15 does not slide out of the arc-shaped groove 13 when rotating, at this time, the rotating shaft 9 drives the second threaded cylinder 12 to rotate through the cooperation of the hemisphere block 14 and the arc-shaped groove 13, and the L-shaped wheel clamping rod 6 moves to the side close to the wheel through the cooperation of the second threaded column and the first threaded cylinder 7.
[0038] When one side of the L-shaped wheel clamping rod 6 contacts the inner contour of the wheel, since the resistance of the second threaded cylinder 12 is large when rotating, the hollow circular plate 15 slides out of the arc-shaped groove 13 when rotating, at this time, the rotating shaft 9 does not drive the second threaded cylinder 12 to rotate, then, the driving motor 8 continues to drive the rotating shaft 9 to rotate, and the other side of the L-shaped wheel clamping rod 6 moves to the side close to the wheel through the rotating rotating shaft 9, until the other side of the L-shaped wheel clamping rod 6 also contacts the inner contour of the wheel, when the four L-shaped wheel clamping rods 6 all contact the corresponding wheels, the driving motor 8 stops driving the rotating shaft 9 to rotate, and the position of the L-shaped wheel clamping rod 6 cannot be changed through the self-locking property between the second threaded cylinder 12 and the first threaded cylinder 7, at this time, the support plate 4 does not roll over when tilting through the L-shaped wheel clamping rod 6.
[0039] When the vehicle on the support plate 4 needs to be tilted, the angle between the support plate 4 and the horizontal plane can be changed by changing the length of the first hydraulic push rod 203, when the first hydraulic push rod 203 is elongated, the support plate 4 rotates counterclockwise, when the first hydraulic push rod 203 is shortened, the support plate 4 rotates clockwise.
[0040] When the vehicle is repaired, the support plate 4 returns to the horizontal state through the first hydraulic push rod 203, and the rotating shaft 9 rotates through the driving motor 8, at this time, since the resistance of the second threaded cylinder 12 is small when rotating, the hemisphere block 14 does not slide out of the arc-shaped groove 13 when the hollow circular plate 15 rotates, at this time, the rotating shaft 9 drives the second threaded cylinder 12 to rotate through the cooperation of the hemisphere block 14 and the arc-shaped groove 13, and the L-shaped wheel clamping rod 6 moves to the side away from the wheel through the cooperation of the second threaded column and the first threaded cylinder 7, when the four L-shaped wheel clamping rods 6 are all separated from the wheels, the vehicle can be removed from the support plate 4.
[0041] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application. Structures, devices and operation methods not specifically described and explained in the present application are implemented according to conventional means in the art, unless otherwise specified and limited.
