Therefore, the lying board car and the cart are simultaneously applied in traditional worker repair. Therefore, it is of great practical significance to improve a multifunctional lying board car to improve the repair work efficiency and provide convenience for automobile repair workers. UTILITY MODEL CONTENT

[0004] The utility model aims to integrate the lying board car and the small cart into one, provide better convenience for automobile repair workers under the premise of portability and light weight, and improve the repair efficiency.

[0005] To achieve the above-mentioned purpose in the future, the technical scheme of the utility model is as follows:

[0006] A multifunctional folding lying board car, comprising a telescopic pull rod unit, a turnover main plate unit, a movement unit and a hard mounting plate. The telescopic pull rod unit is located on both sides of the turnover main plate unit and comprises a compression spring, a spring pull rod, a buckle type fixing disc, a telescopic rod and a telescopic control switch, which are used to control the movement of the lying board strategy. The turnover main plate unit is located at the center of the lying board car and comprises a soft plastic shell, a central pull rod, a card shaft, a support rod and a steel rope, which are used to carry people and goods. The movement unit is located at the bottom of the support rod of the turnover main plate unit and comprises a universal wheel, which is used for the translation of the lying board. The hard mounting plate is located directly above the turnover main plate unit and is used for carrying objects.

[0007] As an improvement, the telescopic pull rod unit is provided with a compression spring, a spring pull rod and a buckle type fixing disc. Six pin holes are punched on the buckle type fixing disc, each with an interval of 30°. The spring pull rod can adjust the angle of the telescopic rod to adapt to people of different heights.

[0008] As a further improvement, the telescopic pull rod unit is provided with a telescopic rod, and the telescopic control switch is arranged on the top of the telescopic rod, so that the telescopic length of the telescopic rod can be adjusted to adapt to people of different heights.

[0009] As an improvement, the turnover main plate unit is provided with a central main shaft, which is located at the horizontal center of the soft plastic shell and can manually rotate the soft plastic shell to rotate the turnover main plate unit by 180 degrees.

[0010] As a further improvement, the turnover main plate unit is provided with a central pull rod located at the right center of the soft plastic shell, and the auxiliary workpiece is arranged on the central pull rod, which is a steel rope, a compression spring and a plug shaft. The first section of the steel rope is fixed on the central pull rod, and the tail end is fixed on the inside center of the plug shaft. The inside end of the compression spring is fixed on the soft plastic shell, and the outside is fixed on the inside of the plug shaft. The plug shaft is installed on the pin hole of the soft plastic shell.

[0011] As a further improvement, the auxiliary workpiece is driven by the central pull rod, which pulls the steel rope and the plug shaft inward, and the compression spring between the plug shaft and the soft plastic shell is compressed, so that the plug shaft is separated from the plug hole in the support rod, and the turnover main plate unit is unlocked, providing 180 degrees of horizontal freedom for the turnover main plate unit.

[0012] As a further improvement, the soft plastic shell is provided with a hard mounting plate located above the soft plastic shell, and the length and width dimensions are equal to those of the soft plastic shell, which provides effective bending resistance for the turnover main plate unit.

[0013] As a further improvement, the turnover main plate unit has a soft plastic shell on one side and a hard steel plate on the other side. Therefore, when the mechanic needs to drill into the bottom of the car for repair, the soft plastic shell side can be used, and when the goods need to be transported, the hard mounting plate side can be used.

[0014] As described above, the present application combines the functions of the lying board and the trolley by combining the pull rod telescopic unit with the turnover main plate unit, so that the structure becomes more compact, the use is more convenient, and the efficiency is improved.

[0022] Example 1

[0023] like Figure 1 As shown, this multifunctional folding reclining cart includes a telescopic lever unit 10, a flip-top main board unit 20, and a motion unit 30. The telescopic lever unit 10 is located on the left and right sides of the flip-top main board unit 20 and is used to switch to cart mode and adjust the cart's direction of movement; the flip-top main board unit 20 is located at the center of the main body and is used to carry people and goods; the motion unit 30 is located at the bottom of the flip-top main board unit 20 and is used to drive the reclining cart to slide.

[0024] like Figure 2 , Figure 3 , Figure 4 As shown, the telescopic rod unit 10 is located at the bottom of the flip mainboard unit 20. The telescopic rod unit 10 includes a compression spring 101, a spring bar 102, and a snap-fit ​​fixing plate 103. The compression spring 101 is compressed by default, causing the spring bar 102 to snap into the pin hole of the snap-fit ​​fixing plate 103, thus fixing the telescopic rod unit 10. The snap-fit ​​fixing plate 103 has 6 pin holes spaced 30° apart. When the telescopic rod unit 10 rotates, it can be adjusted to different angles to accommodate people of different heights and provide a fixing function. The telescopic rod unit 10 includes a telescopic rod 104, which includes a telescopic control switch 106. When the user needs to adjust the height of the telescopic rod 104, they can adjust the height by pressing the telescopic control switch 106 to accommodate people of different heights and increase the comfort of using this utility model.

[0025] like Figure 5As shown, the flip-up mainboard unit 20 includes a soft plastic shell 201, a central pull rod 202, a retaining shaft 203, a compression spring 204, a support rod 206, and a steel cable 207. The central pull rod 202 is located at the right central axis of the soft plastic shell 201 and can be pulled back and forth. The retaining shaft 203 is located in the mounting through hole of the soft plastic shell 201 and can move inward and outward with the steel cable 207. The compression spring 204 is located between the retaining shaft 203 and the soft plastic shell 201, and the inner side of the compression spring 204 is fixed to the soft plastic shell 201. The outer side is fixed to the inner surface of the retaining rod 203; the first end of the steel rope 207 is fixed to the central pull rod 202, and the last end is fixed to the center of the inner surface of the pull rod 203; the entire flip main board unit 20 is in a locked state by default. Pulling the central pull rod 202 outward causes the central pull rod 202 to drive the steel rope 207, which in turn drives the retaining rod 203 to press the compression spring 204, causing the retaining rod 203 to leave the internal pin hole of the support rod 206, thus unlocking the flip main board unit 20; releasing the central pull rod 202 causes the flip main board unit 20 to return to its locked position.

[0026] like Figure 6 As shown, the flip motherboard unit 20 includes a central spindle 205 and a rigid mounting plate 40 is mounted on it. When the internal device of the flip motherboard unit 20 is unlocked, the flip motherboard unit 20 can rotate 180° so that either the rigid mounting plate 40 or the soft plastic shell 201 faces upward. When a flatbed cart is needed, the flip motherboard unit 20 can be rotated 180° so that the soft plastic shell 201 faces upward, providing a comfortable backrest for maintenance personnel. When a flatbed cart is needed, it can be rotated 180° in the opposite direction so that the rigid mounting plate 40 faces upward, providing a solid chassis for transporting goods.
