Description

Technical Field

[0001] The utility model relates to the technical field of rolling curtain structures for rear hopper boxes, and specifically relates to a rolling curtain for a flexible rear hopper box. Background Technique

[0002] The rear hopper box is an important structure on a freight truck and is used to load goods. A rolling curtain is often provided on the rear hopper box to play a role in shielding and protection. However, there are still some defects when the rolling curtain for the rear hopper box is specifically used.

[0003] The rolling curtain for the rear hopper box is often an integrated metal or rigid plastic structure, with poor softness and difficult folding operation. Moreover, it is integrally fixed and difficult to achieve the function of modular assembly, which makes the device difficult to transport or maintain. Secondly, the rolling curtain structure for the rear hopper box often does not have a bird repelling structure and a solar energy utilization structure installed, which causes the device to be easily damaged and polluted by small animals such as birds, and it is also not easy to fully absorb and utilize solar energy to supplement the electric energy of the freight truck, and the functionality is not high. Based on this, we propose a new type of rolling curtain for a flexible rear hopper box to provide better use effects and achieve the advantages of multiple functions. Content of the Utility Model

On the other hand, by providing a metal mesh reinforcement layer inside the side wall of the flexible composite curtain cloth, and the material of the metal mesh reinforcement layer is aluminum alloy, the structural strength of the flexible composite curtain cloth is optimized. And by providing a fireproof fiber cloth layer on the side of the flexible composite curtain cloth close to the first arc-shaped support rib, and the material of the fireproof fiber cloth layer is asbestos fiber, the fireproof and flame-retardant performance of the inner side of the flexible composite curtain cloth is improved.

[0016] (3) The rolling curtain for the flexible rear trunk uses components such as a flexible photovoltaic panel. When the rolling curtain structure is specifically operated, the flexible photovoltaic panel can absorb solar energy from the external environment when the flexible composite curtain cloth is unfolded, and convert the solar energy into electrical energy through a photovoltaic controller and store it in a rechargeable lithium battery for the truck to use. This enables the device to use solar energy to supplement the electrical energy of the truck where the rear trunk is located, achieving the advantage of energy conservation and strong practicality. Moreover, by using the sonic bird repeller installed on the outer wall of the battery box, it can emit sound waves to drive small animals such as birds away and prevent them from perching on the device and causing damage by gnawing.
