Description

Technical Field

[0001] This invention pertains to transportation vehicles, specifically a pure electric cold-region agricultural freight vehicle with automatic photovoltaic panel charging. Background Technology

[0002] In recent years, with the gradual depletion of non-renewable oil reserves, coupled with the impact of vehicle emissions from gasoline, diesel, and kerosene on the atmospheric environment and human health, humanity has begun to shift towards the research and development of new energy vehicles, among which electric vehicles are one. These vehicles have experienced rapid development due to their advantages such as low noise, no environmental pollution, and no harm to human health. However, due to structural design deficiencies, existing pure electric vehicles lack self-charging structures and functions. When the battery runs out of power, the vehicle must be parked and charged using charging stations, increasing both operating costs and reducing operational efficiency. These problems are even more pronounced in pure electric freight and agricultural vehicles used in cold northern regions. The battery loss and consumption of freight vehicles in high-altitude and cold regions are greater than those of similar models in warmer regions. Therefore, the rapid battery depletion, high charging frequency, and high operating costs of freight vehicles in high-altitude and cold regions are urgent technical problems that need to be addressed. Furthermore, charging stations are scarce in rural areas, making charging extremely inconvenient. Summary of the Invention

[0003] The purpose of this invention is to address the problems existing in the prior art and, in combination with the actual needs of pure electric freight vehicles in high-altitude and cold regions, to develop and design a photovoltaic-panel-automatic-charging pure electric agricultural freight vehicle for cold regions. This aims to achieve the goals of photovoltaic panels automatically charging the pure electric freight vehicle in real time, reducing the frequency of external charging, lowering operating costs, and improving vehicle operating efficiency.

[0004] The purpose of this invention is achieved as follows: A stepped telescopic frame is configured above the floor of the truck bed. The front end of the stepped telescopic frame is hinged to the truck frame assembly. A photovoltaic panel is fixedly mounted on the stepped telescopic frame. A locking hook is swayably hinged on the truck frame assembly above the hinge point between the stepped telescopic frame and the truck frame assembly. The locking hook is in a snap-fit ​​engagement with the stepped telescopic frame or is not in a snap-fit ​​engagement with it. A voltage converter is installed on the truck frame assembly. Wires connect the voltage converter to the photovoltaic panel and the battery respectively. This constitutes a photovoltaic panel-automatic charging pure electric cold-region agricultural freight truck.

[0005] This invention utilizes a photovoltaic panel structure mounted on a pure electric agricultural freight vehicle used in high-altitude and cold regions. This allows the vehicle to automatically replenish its battery in real time while in operation or at rest, reducing the frequency of charging stops, lowering charging costs, and improving operating efficiency. The structure is simple and reasonable, with low manufacturing costs and easy and convenient operation, making it particularly suitable for use with pure electric agricultural freight vehicles in high-altitude and cold regions.

[0011] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. A photovoltaic panel-equipped, self-charging, pure electric cold-region agricultural freight vehicle comprises a drive motor 2, a coaxial clutch connector 3, and a gearbox 4, sequentially mounted from front to back on the lower front side of the truck frame assembly 1. The coaxial clutch connector 3 connects the drive motor 2 to the gearbox 4. A battery 5 is installed on the lower middle part of the truck frame assembly 1, and electrical wires connect the battery 5 to the drive motor 2. A truck body 7 is fixed to the upper side of the truck frame assembly 1. A stepped telescopic frame 6 is configured above the bottom plate of the truck body 7. The front end of the stepped telescopic frame 6 is hinged to the truck frame assembly 1. A photovoltaic panel 10 is fixedly mounted on the stepped telescopic frame 6. A locking hook 8 is pivotally mounted on the truck frame assembly 1 at a position above the hinge point between the stepped telescopic frame 6 and the truck frame assembly 1. The locking hook 8 is in a snap-fit ​​engagement with the stepped telescopic frame 6 or is not in a snap-fit ​​engagement with it. A voltage converter 9 is mounted on the truck frame assembly 1. Wires connect the voltage converter 9 to the photovoltaic panel 10 and the battery 5, respectively.

[0012] When in operation, if the agricultural freight vehicle is empty or parked without cargo, the stepped telescopic frame 6 is extended and unfolded on the floor of the truck bed 7. Sunlight shines on the photovoltaic panel 10, and the electricity generated by the photovoltaic panel 10 is input into the battery 5 through the voltage converter 9, completing the real-time charging and replenishment operation. When the freight vehicle is fully loaded, the stepped telescopic frame 6 is pushed back and then lifted forward and upward into an upright position. The stepped telescopic frame 6 is locked vertically by the locking hook 8, at which point the replenishment of electricity to the battery 5 stops. The extension area of ​​the stepped telescopic frame 6 can be adjusted according to the area occupied by the cargo in the truck bed 7, thereby changing the amount of electricity replenished, making it highly adaptable.
