Carriage protection awning device with folding and unfolding functions for automobile freight

Abstract

The invention discloses a carriage protection awning device with folding and unfolding functions for automobile freight. The carriage protection awning device comprises a installation rail, a front-end moving block and a middle moving block. The device has the beneficial effects that the front-end moving block, a driving motor, a driving wheel and a photovoltaic panel are adopted. When a tarpaulin is opened, the driving motor drives the driving wheels to move in the installation rails. Therefore, the front-end moving block is driven to move towards the rear portion of the compartment, the tarpaulin is driven to move, and the tarpaulin moves to drive the moving wheel of the middle moving block to roll; Thus, the tarpaulin between the middle moving block is driven to open in turn, so as to fully open the tarpaulina. The driving motor supplies power through electric energy which is generated by a photovoltaic panel and stored in a storage battery, the trouble of pulling an electric wire and refitting a circuit is omitted, installation and use are more convenient, the tarpaulin is opened in the mode that the driving motor drives a driving wheel to rotate. The trouble of installation a driving chain is omitted, and the overall installation and use are further facilitated, so that the installation and dismounting efficiency is greatly improved, and the use convenience is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle transportation, in particular to a protective canopy device for a car compartment with a retractable function for automobile freight. Background technique [0002] In the road cargo transportation of bulk trucks, in order to prevent the goods from being rained, wind blown, bumped and dropped, etc., it is necessary to cover the goods with tarpaulins. Most of the tarpaulins covered by semi-trailers are manually retracted, which is very troublesome to use. At the same time, due to the particularity of the semi-trailer, the car is surrounded by a fence that can be opened sideways, and the traditional automatic tarpaulin installed on the muck truck needs to be refitted when the circuit is installed, and the drive chain needs to be installed. Disassembly is very troublesome. Because the traditional automatic tarpaulin installed on the muck truck has a single specification and strong integrity, it is inc...

Problems solved by technology

[0002] In the road cargo transportation of bulk trucks, in order to prevent the goods from being rained, wind blown, bumped and dropped, etc., it is necessary to cover the goods with tarpaulins. Most of the tarpaulins covered by semi-trailers are manually retracted, which is very troublesome to use. At the same time, due to the particularity of the semi-trailer, the car is surrounded by a fence that can be opened sideways, and the traditional automatic tarpaulin installed on the muck truck needs to be refitted when the circuit is installed, and the drive chain needs to be installed. Disassembly is very troublesome. Because the traditional automatic tarpaulin installed on the muck truck has a single specification and strong integrity, it is inconvenient to adjust according to the length of the car. Therefore, the automatic tarpaulin used on the muck truck cannot be installed on a semi On the trailer compartment, further improvements can be made to make it easy to install and use on the semi-trailer compartment
