Description

Technical Field

[0001] The utility model relates to the technical field of automobile modification, in particular to a flap assisting device for a hidden tailgate. Background Art

[0002] A tail lift is a lifting and loading equipment installed at the rear of a vehicle. It can greatly improve the efficiency of transportation and loading and unloading. It is an essential equipment for modern logistics and transportation. It is widely used in logistics, finance, petrochemicals, tobacco, commerce, manufacturing and other industries.

[0003] The traditional hidden tailgate relies entirely on manual flipping during use, which is time-consuming and labor-intensive. It is not only inconvenient, but also cannot be designed too large in terms of design due to the limitation of manual flipping. Otherwise, the flipping action cannot be completed by manpower, which greatly limits the application scenarios of this type of tailgate. To this end, we propose a flipping assist device for the hidden tailgate. Utility Model Content

[0004] In view of the problems existing in the above-mentioned existing flap assisting device of the under-hidden tailgate, the present utility model is proposed.

[0005] Therefore, the purpose of the utility model is to provide a flap-assisting device for an under-hidden tailgate, which solves the problem that the traditional under-hidden tailgate completely relies on manual flipping of the board during use, which is time-consuming and labor-intensive, not only inconvenient, but also in terms of design, the size of the board cannot be designed to be too large due to the limitation of manual flipping, otherwise the flipping action cannot be completed by manpower, which greatly limits the problem of the application scenarios of this type of tailgate.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A flap assisting device for a hidden tailgate comprises a frame assembly, a follower frame assembly, a lifting arm assembly, a crank arm and a lifting cylinder, wherein the frame assembly and the follower frame assembly are connected and fixed by a shaft, the lifting arm assembly and the frame assembly are connected and fixed by a shaft, one end of the lifting cylinder is connected and fixed to the frame assembly by a shaft, and the other end of the lifting cylinder is connected and fixed to the lifting arm assembly by a shaft.

[0008] Preferably, the lifting arm assembly is provided with a large plate welding support, the large plate welding support is provided with a pin shaft, the crank arm is assembled on the pin shaft and fixed with a flat washer and a hexagonal nut, and the large plate welding support is provided with a triangular limiting plate.

[0009] Preferably, a connecting plate is welded on the lifting arm assembly, a connecting rod is fixedly connected to the connecting plate via a nut, a spring is provided on the connecting rod, and the other end of the spring is connected to the crank arm.

[0010] Preferably, a guide wheel is welded on an outer wall of one side of the frame assembly.

[0011] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0012] When the utility model is in use, the lifting cylinder pushes the lifting arm down, and the large board is lifted up by the guide wheel. When the board surface is lifted up to nearly vertical, the board surface is manually turned flat, and the large board is now fully opened. When closing the large board, the lifting cylinder moves the large board to a horizontal position. At this time, the spring applies a counterclockwise torque to the crank arm to assist manpower in turning the large board over and returning the large board to its original position, and the large board is now fully retracted. Through the above-mentioned structural arrangement, the turning of the bottom-hidden folding tail board is easier and simpler, and the use is convenient and fast, the structure is compact and reasonable, the production cost is low, and it is suitable for mass production. In addition, the depth and breadth of the design are improved, so that the application prospects of this type of tail board are more extensive. BRIEF DESCRIPTION OF THE DRAWINGS
