AI Technical Summary

Technical Problem

Existing electric tarpaulin mechanisms are difficult to achieve the flipping action of the tarpaulin, which can easily obstruct the cargo box during loading and unloading, affecting loading and unloading efficiency. In addition, the mechanism structure is fixed and cannot adapt to the needs of cargo boxes of trucks with different heights.

Method used

By adjusting the height of the lifting main frame, combined with the tarpaulin positioning top frame and the flipping control component, the automatic linkage of the tarpaulin's shrinking, lifting, flipping and resetting actions is realized. Multiple drive methods are adopted to adapt to different load and precision requirements.

Benefits of technology

It achieves fully automated operation of tarpaulins, breaking through the single-function limitations of existing technologies, adapting to different truck cargo box heights, and improving loading and unloading efficiency and adaptability.

Abstract

The application provides a truck electric canopy automatic folding and turning structure, and relates to the technical field of truck electric canopy folding and unfolding. The truck electric canopy automatic folding and turning structure comprises a lifting main frame, a canopy positioning top frame and a turning control assembly. The lifting main frame is provided with a side lifting frame on each side. The lifting main frame comprises a frame bottom frame, a U-shaped buckle frame, a guide edge pipe, a first screw rod seat, a first long screw rod, a fourth bevel gear, a first motor, a second bevel gear, a third bevel gear, a control rod and a first bevel gear. The turning control assembly comprises a swing type support pipe and a rear support guide pipe. The technical key points are as follows: the height of the lifting main frame is adjusted, the canopy covering the top of the canopy positioning top frame is driven to adjust the size of the two sides under the cooperation of the side lifting frame, and the canopy positioning top frame is controlled to turn from the top to the side edge between the lifting main frame and the canopy positioning top frame by the turning control assembly, so that full-process automation linkage can be realized, and the limitation of single function of the prior art is broken through.
