[0035] Example

[0036] Reference Figures 1 to 3 In order to solve the technical problem that the above-mentioned lying board tool for automobile maintenance assistance has potential safety hazards, the utility model provides an automobile maintenance auxiliary tool, including: a U-shaped flatbed 1, two protection mechanisms 2 and a lying mechanism 3. A mounting block 4 is fixedly provided at one end of the U-shaped flatbed 1, and a handle 5 is hinged on the mounting block 4, so that the U-shaped flatbed 1 can be dragged and moved by the rotatable handle 5. The two protection mechanisms 2 are arranged on both sides of the top of the U-shaped flatbed 1, so that the weight of the falling vehicle can be borne by the two protection mechanisms 2, so as to avoid the vehicle directly falling on the maintenance personnel, and increase the protection effect of the tool. The lying mechanism 3 is arranged below and between the two protection mechanisms 2, and the lying mechanism 3 is respectively connected to the two protection mechanisms 2 so as to provide a lying space for the maintenance personnel through the lying mechanism 3, and by arranging the lying mechanism 3 below and between the two protection mechanisms 2, there can be a height difference between the lying mechanism 3 and the two protection mechanisms 2, and the maintenance personnel are within this height difference, so that the falling vehicle can fall on the protection mechanism 2, thereby avoiding contact between the vehicle and the maintenance personnel in the lying mechanism 3, thereby achieving the effect of increasing the safety of the tool.

[0037] For further information, please refer to Figure 1 to Figure 2 As shown, in this embodiment, in order to facilitate the description of the two protection mechanisms 2, one of the protection mechanisms 2 is used as an example for description. The protection mechanism 2 includes: a hydraulic cylinder 21, a support plate 22 and an extension plate 23. At least two hydraulic cylinders 21 are embedded on both sides of the top of the U-shaped flatbed 1. The support plate 22 is arranged at one end of the piston rod of the hydraulic cylinder 21, and one end of the piston rod of the hydraulic cylinder 21 passes through the bottom of the support plate 22, so that the support plate 22 can be pushed up and down by the hydraulic cylinder 21, thereby the height of the lying mechanism 3 can be adjusted synchronously to adapt to different annular car maintenance work; it should be supplemented that a filling steel plate 24 is fixedly arranged on the top of the support plate 22, so that the anti-collision ability of the overall support plate 22 is increased by installing the filling steel plate 24, which greatly increases the safety of the tool, and a buffer spring 25 is fixedly arranged between the bottom of the filling steel plate 24 and one end of the piston rod of the hydraulic cylinder 21, so that the impact force of the car falling can be slowed down by the buffer spring 25, thereby ensuring the life safety of the maintenance personnel in the lying mechanism 3. The extension plate 23 is fixedly arranged on one side of the top of the support plate 22, so as to increase the bearing area of ​​the top surface of the support plate 22 by installing the extension plate 23, thereby increasing the contact area with the car and buffering the impact force, thereby achieving the effect of increasing the safety of the tool.

[0038] In a feasible embodiment, in order to ensure that the extension plate 23 will not be deformed when the car falls, a reinforcement frame 26 is fixedly provided at the bottom of the extension plate 23, and one end of the reinforcement frame 26 is connected to the support plate 22.

[0039] For further information, please refer to Figure 1 and Figure 3 As shown, in this embodiment, the lying mechanism 3 includes: a support frame 31, a lying board 32 and a tool cabinet 33. One end of at least two support frames 31 is fixedly arranged on one side of the support plate 22. The lying board 32 is fixedly arranged on the top of the support frame 31, so that the maintenance personnel can lie on the lying board 32 to repair the car, and the support frame 31 can support and protect the lying board 32. The tool cabinet 33 is fixedly arranged on one side of the top of the lying board 32, and the tool cabinet 33 is designed to store tools, so that the user can store and use tools conveniently.

[0040] It should be explained separately that there is a height difference between the top of the lying board 32 in the lying mechanism 3 and the top of the supporting board 22, and the lying board 32 can rise and fall along with the supporting board 22. If the supporting board 22 falls due to a collision, the lying board 32 will also fall together, and the maintenance personnel on the lying board 32 are in a safe space with a height difference, so they will not be oppressed by the car and are thus protected.

[0041] In a feasible embodiment, in order to provide a comfortable maintenance environment for maintenance personnel during maintenance, a non-slip cushion 34 is laid on the top of the lying board 32 .

[0042] How it works

[0043] When using the tool to repair a car, the U-shaped cart can be pushed under the car by turning the handle 5. According to the height difference between the bottom of the car and the ground, the height of the lying board 32 between the two supporting boards 22 can be adjusted by the hydraulic cylinder 21 pushing the supporting board 22 up. After the adjustment is completed, the maintenance personnel can lie on the lying board 32 to repair the car. In an emergency, if the car suddenly falls, the car will first contact the supporting board 22. After the supporting board 22 is hit by the top, the buffer spring 25 inside it will buffer part of the impact force. When the supporting board 22 falls due to the weight of the car, the lying board 32 will also fall. There is a height difference between the lying board 32 and the supporting board 22. The maintenance personnel at this height difference will not be oppressed by the car, thereby ensuring the life safety of the maintenance personnel.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
