[0036] Furthermore, four universal wheels 13 are symmetrically arranged on the surface of the lying board 1 facing away from the mesh pad 4. The universal wheels 13 are connected to the lying board 1 through hinges 14. One end of the universal wheel 13 is installed on the hinge 14, and the other end of the universal wheel 13 moves closer to or away from the lying board 1 as the hinge 14 rotates. Two universal wheels 13 are respectively arranged on the first support plate 2 and the second support plate 3.

A movable plate 16 is movably provided on the mounting box 15, and a positioning rod 161 is provided on the movable plate 16. The positioning rod 161 is located in the arc-shaped guide groove 152. When the positioning rod 161 moves along the arc-shaped guide groove 152, it drives the connecting rod 151 to rotate, and the rotation of the connecting rod 151 drives the rotating shaft of the hinge 14 to rotate.

[0038] Furthermore, a wedge block 162 is provided on the side of the movable plate 16 facing away from the positioning rod 161, and a fixed block 18 cooperating with the wedge block 162 is provided on the side of the lying plate 1 facing away from the mesh pad 4, and a spring 17 abutting against the movable plate 16 is provided in the installation box 15; in the process of the lying plate 1 changing from the unfolded state to the folded state, the fixed block 18 abuts against the inclined surface of the wedge block 162, so that the movable plate 16 moves toward the universal wheel, and the spring 17 is changed from the normal state to the stretched state by the action of the movable plate 16.

[0039] Furthermore, a slide groove 24 is provided on the first support plate 2, and the mounting seat 21 is movably arranged in the slide groove 24. The headrest 23 moves along the setting direction of the slide groove 24 with the mounting seat 21.

[0040] Furthermore, a first power source 61 for supplying power to the illuminating lamp 6 is disposed on the side surface of the first supporting plate 2 , and the illuminating lamp 6 is connected to the first power source 61 via a serpentine metal tube 62 .

[0041] Furthermore, LED light strips 7 are disposed on the side surfaces of the first support plate 2 and the second support plate 3 .

[0042] Furthermore, a second power source 27 and a socket 28 connected to the second power source 27 are provided on a side of the first support plate 2 facing away from the mesh pad 4 .

[0043] In a specific embodiment, Figures 1 to 9As shown, a car maintenance lying plate vehicle proposed in the present application is mainly used in the working situation that maintenance personnel need to enter the bottom of the car chassis for maintenance. The lying plate 1 is composed of a first support plate 2 and a second support plate 3, and the two are movably connected by a rotating rod 11. Specifically, two first fixing seats 25 are fixedly installed on both sides of the bottom of the first support plate 2, and correspondingly, two second fixing seats 31 are provided on both sides of the bottom of the second support plate 3. Each of the first fixing seat 25 and the second fixing seat 31 is provided with a through hole, and the positions of these four through holes are in a straight line and are all passed through by the rotating rod 11. This design enables the first support plate 2 and the second support plate 3 to move along the axial direction of the rotating rod 11 to unfold or fold the lying plate 1. Specifically, the end of the first support plate 2 and the second support plate 3 away from the rotating rod 11 can move with the rotation of the rotating rod 11, and the lying plate 1 is in a folded state when the first support plate 2 and the second support plate 3 move close to each other to the maximum distance. A first limit block is provided on the side of the first support plate 2 facing away from the first fixing seat 25, and a second limit block is provided on the side of the second support plate 3 facing away from the second fixing seat 31. When the first support plate 2 and the second support plate 3 move away from each other and become parallel to each other, the first limit block abuts against the second limit block to prevent the first support plate 2 and the second support plate 3 from over-turning, so that the first support plate 2 and the second support plate 3 are parallel to each other to form a plane, and the lying plate 1 is in the unfolded state. This design makes the lying plate 1 compact in structure in the folded state, occupies less space, and is convenient for storage and transportation; when the lying plate 1 is in the unfolded state, the first support plate 2 and the second support plate 3 together form a plane, so that maintenance personnel can lie steadily on this plane to perform maintenance work on the car.

[0044] Here, a first positioning plate 26 is provided on the side of the first support plate 2 facing away from the mesh pad 4, and a positioning hole is provided on the first positioning plate 26. A second positioning plate 32 is provided on the side of the second support plate 3 facing away from the mesh pad 4, and a positioning column 33 is movably installed on the second positioning plate 32, and the size and number of the positioning column 33 and the positioning hole are consistent. When the lying board 1 is in a folded state, the first support plate 2 and the second support plate 3 are close to each other. At this time, the positioning column 33 on the second positioning plate 32 and the positioning hole on the first positioning plate 26 are in the same plane. By inserting the positioning column 33 into the positioning hole, the first support plate 2 and the second support plate 3 can be locked together to ensure that the lying board 1 remains in a folded state. This design effectively prevents the lying board 1 from accidentally unfolding due to external forces (such as shaking) during storage or transportation of the present application, thereby improving the overall stability and safety. When it is necessary to use the automobile repair flatbed cart proposed in the present application to repair an automobile, the maintenance personnel first pull out the positioning column 33 from the positioning hole, and then rotate the first support plate 2 and the second support plate 3 to change the flatbed 1 from a folded state to an unfolded state for use.

[0045] It should be noted that four universal wheels 13 are arranged on the side of the lying board 1 facing away from the mesh pad 4, and these universal wheels 13 are connected to the lying board 1 through hinges 14. Specifically, one end of the universal wheel 13 is fixed on the hinge 14, and the other end can move closer to or away from the lying board 1 as the hinge 14 rotates. When the lying board 1 is in a folded state not in use, the design of the hinge 14 connection enables the universal wheel 13 to be close to the lying board 1 so as to be conveniently stored, effectively saving space, while also avoiding potential interference or collision of the universal wheel 13 by the surrounding environment, playing a protective role. Two universal wheels 13 are respectively installed on the first support plate 2 and the second support plate 3. These four universal wheels 13 are symmetrically designed to ensure the balance and stability of the overall structure. When the lying board 1 is in the unfolded state, under the action of the universal wheels 13, the maintenance personnel can easily move the lying board 1, which enables the present application to move freely under the bottom of the car, so that the maintenance personnel on the lying board 1 can quickly move to the position at the bottom of the car that needs to be repaired.

[0046] It should be noted that a mounting box 15 is arranged next to each universal wheel 13, and a connecting rod 151 connected to the rotating shaft of the hinge 14 is arranged in the mounting box 15, and an arc-shaped guide groove 152 is arranged on the connecting rod 151. A movable plate 16 is movably arranged on the mounting box 15, and a positioning rod 161 is arranged on the movable plate 16. The positioning rod 161 is embedded in the arc-shaped guide groove 152. When the positioning rod 161 moves along the arc-shaped guide groove 152, it drives the connecting rod 151 to rotate, and the rotation of the connecting rod 151 drives the rotating shaft of the hinge 14 to rotate. In order to ensure that the movable plate 16 can drive the connecting rod 151 to rotate, guide grooves are also set on both sides of the installation box 15, and protrusions are set on both sides of the movable plate 16. The protrusions are embedded in the guide grooves, so that the movable block can only move linearly along the setting direction of the guide groove, ensuring that the positioning rod 161 moves linearly in the arc-shaped guide groove 152 of the connecting rod 151 with the movement of the movable block, and the arc-shaped design of the arc-shaped guide groove 152 drives the connecting rod 151 to rotate. This design allows the hinge 14 to rotate with the movement of the movable plate 16, so that the universal wheel 13 is close to or away from the lying plate 1. A wedge block 162 is provided on the side of the movable plate 16 facing away from the positioning rod 161, a fixed block 18 cooperating with the wedge block 162 is provided on the side of the lying plate 1 facing away from the mesh pad 4, a spring 17 is provided inside the installation box 15 to abut against the movable plate 16, one end of the spring 17 is fixed to the end of the installation box 15 away from the connecting rod 151, and the other end of the spring 17 is fixed to the end of the movable plate 16 close to the positioning rod 161. Since two universal wheels 13 are respectively provided on the first support plate 2 and the second support plate 3, two fixed blocks 18 are also provided on the first support plate 2 and the second support plate 3 accordingly. When the lying plate 1 is in the folded state, the fixed block 18 on the first support plate 2 contacts the movable plate 16 next to the universal wheel 13 on the second support plate 3, and the fixed block 18 on the second support plate 3 contacts the movable plate 16 next to the universal wheel 13 on the first support plate 2. Specifically, when the lying board 1 is transformed from the unfolded state to the folded state, the fixed block 18 gradually contacts the inclined surface of the wedge block 162 and exerts a force on the wedge block 162, forcing the movable board 16 to move toward the universal wheel 13. In this process, the spring 17 is squeezed by the movable board 16 and changes from a normal state to a stretched state, and the hinge 14 rotates with the movement of the movable board 16, and the universal wheel 13 installed on the hinge 14 is then close to the lying board 1, so that the universal wheel 13 can be automatically stored as the lying board 1 enters the folded state.During the transition of the lying board 1 from the folded state to the unfolded state, the fixed block 18 and the wedge block 162 are gradually separated. At this time, the spring 17 is restored to the normal state from the stretched state, and the movable plate 16 moves in the direction away from the universal wheel 13 under the elastic force of the spring 17, driving the hinge 14 to rotate in the opposite direction. The universal wheel 13 installed on the hinge 14 gradually moves away from the lying board 1 and is finally fully unfolded to contact the ground, so that the universal wheel 13 can automatically unfold as the lying board 1 enters the unfolded state, ensuring that the lying board 1 can be moved by the universal wheel 13 in the unfolded state.

[0047] Here, a mesh pad 4 is also provided on the lying board 1. Specifically, the first support board 2 and the second support board 3 are both provided with a mesh pad 4 for supporting the back and waist of the maintenance personnel on the side facing away from the universal wheel. This is because when the maintenance personnel perform maintenance work on the bottom of the car on the lying board 1, maintaining the same posture for a long time is often prone to muscle fatigue, thereby affecting the maintenance operation. The design of the mesh pad 4 effectively relieves the muscle pressure on the back and waist of the maintenance personnel, promotes local blood circulation, and thus reduces the discomfort caused by long-term work. In addition, the supporting function of the mesh pad 4 also helps the maintenance personnel maintain a more natural body posture, reduces potential injuries that may be caused by improper posture, and further improves work efficiency and work safety. In addition, a plurality of cooling fans 12 are also provided in the first support board 2 and the second support board 3, and the air outlets of these cooling fans 12 are arranged upward to blow air to the mesh pad 4. This design further enhances the air permeability of the mesh pad 4. The cooling fan 12 allows the air on the surface of the mesh pad 4 to circulate continuously, effectively alleviating the stuffiness felt by maintenance personnel when they work on the lying board 1 for a long time, thereby creating a more comfortable working environment for maintenance personnel.

[0048] Among them, a slide groove 24 is provided on the upper surface of the end of the first support plate 2 away from the rotating rod 11, and a mounting seat 21 is movably provided in the slide groove 24. The mounting seat 21 can move smoothly in the slide groove 24, and a universal ball 22 is installed above the mounting seat 21, and the headrest 23 is installed on the universal ball 22. Due to the spherical structure of the universal ball 22, the headrest 23 can not only move with the movement of the mounting seat 21 in the slide groove 24 to adapt to the change of the head position of the maintenance personnel by connecting with the universal ball; at the same time, the headrest 23 can also rotate and tilt on the universal ball 22, further meeting the maintenance personnel's needs for head and neck support in different postures. This design allows the maintenance personnel to adjust the headrest 23 to a position that always provides support for the head and neck when performing maintenance work at the bottom of the car, no matter how their body moves or how their posture changes. This not only greatly alleviates the neck and head fatigue caused by long hours of work for maintenance personnel, but also effectively prevents occupational diseases that may be caused by improper posture, further improves the comfort of the maintenance environment, and thus improves work efficiency.

[0049] Tool boxes 5 are also provided on both sides of the lying board 1. Specifically, the tool boxes 5 are provided on both sides of the second support board 3. This is because when the maintenance personnel lies on the lying board 1, their heads are located on the headrest 23 of the first support board 2, their backs are located on the mesh pad 4 of the first support board 2, and their hands are located on the mesh pad 4 of the second support board 3. Since the maintenance personnel cannot stand up due to the small space when performing maintenance under the car, the tool boxes 5 are provided on the second support board 3 near the hands of the maintenance personnel, so that the maintenance personnel can use the tools while lying down, and do not need to get out from the bottom of the car to look for the tools, thus saving the maintenance personnel time in looking for the tools during maintenance work. There are multiple detachable partitions 51 in the tool box 5. By adjusting the positions of the partitions 51 or completely removing the partitions 51, the tool box 5 can flexibly adapt to maintenance tools of different sizes, which can ensure the classified management of small tools and provide storage space for larger tools. And because tool boxes 5 are arranged on both sides of the second support plate 3, there are two tool boxes 5 in total, and a partition 51 can be arranged in one tool box 5 for classifying and storing small tools, while the other tool box 5 remains without the partition 51 and is specially used for storing bulky tools. Maintenance personnel can choose whether to use the partition 51 according to actual conditions. And the tool box 5 is movably mounted on the side of the second support plate 3 through the hinge 52. When the lying plate 1 enters the folded state, the tool box 5 can also move toward the second support plate 3 under the action of the hinge 52, thereby reducing the floor space and facilitating storage.

[0050] Among them, on the side of the first support plate 2, on one side of the headrest 23, a lighting lamp 6 is provided. A first power supply 61 for powering the lighting lamp 6 is installed on the side of the first support plate 2, and the lighting lamp 6 is connected to the first power supply 61 through a serpentine metal tube 62. There is a skeleton composed of metal sheets inside the serpentine metal tube 62, so that the serpentine metal tube 62 can be bent arbitrarily and maintained in a desired shape, so that the lighting lamp 6 can be adjusted to different angles and directions, and the irradiation area can be adjusted according to the actual needs of the maintenance personnel, and the maintenance area can be illuminated. Here, LED light strips 7 are arranged on the side edges of the first support plate 2 and the second support plate 3. When the maintenance personnel use a car maintenance lying flat car proposed in this application to enter the bottom of the car for maintenance work, the LED light strip 7 is turned on to make the LED light strip 7 emit light. This design can not only provide auxiliary lighting effect for the maintenance personnel, but more importantly, it plays an important warning role. The lighting of the LED light strip 7 clearly conveys the information of "someone under the car" to the surrounding personnel and passing vehicles, avoids the occurrence of accidental collisions or injuries, and improves the safety during maintenance work.

[0051] In addition, a second power source 27 and a socket 28 connected to the second power source 27 are provided on the side of the first support plate 2 facing away from the mesh pad 4. This design is intended to solve the power supply problem of the electric-driven maintenance tools in the maintenance work, and improve the work efficiency and convenience. The second power source 27 is a dual-purpose design of storage type and plug-in type. In other embodiments, the number of sockets 28 can also be arranged according to actual needs to ensure that the power supply needs of multiple power tools can be met simultaneously during the maintenance process. When multiple power tools need to be used at the same time, the maintenance personnel only need to power the second power source 27 through a power line (whether in storage mode or plug-in mode), so that all power tools can operate stably without worrying about the problem of insufficient power. This design avoids the problem of line confusion caused by the variety of power tools used in traditional maintenance operations, avoids the potential safety hazards caused by the interlacing and confusion of lines, and also improves the cleanliness and safety of the maintenance environment.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
