[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1 to 4As shown, this embodiment provides a self-generating device for a commercial vehicle, which includes: a photovoltaic power generation assembly 1 and a power supply control system. The photovoltaic power generation assembly 1 includes a photovoltaic panel 101 and a top cover 102. The top cover 102 is mounted on the vehicle body and is made of a transparent material. The photovoltaic panel 101 is mounted inside the top cover 102 and can receive sunlight through the top cover 102. The power supply control system is connected between the photovoltaic panel 101 and the vehicle body floor wiring harness 2, which is used to connect to the vehicle's electrical equipment. In this arrangement, based on the principle of photovoltaic power generation, part of the solar energy irradiated on the vehicle body is converted into electrical energy through the photovoltaic panel 101 and transmitted to the vehicle body floor wiring harness 2 through the power supply control system to provide power for the vehicle's electrical equipment, reducing engine load and fuel consumption, effectively improving the energy utilization rate of the commercial vehicle, saving vehicle operating costs, and reducing carbon emissions. At the same time, photovoltaic power supply can completely replace engine idling, reduce noise and exhaust pollution, and achieve zero-emission operation. Especially for new energy commercial vehicles, photovoltaic power generation can supplement charging, extend battery life, and reduce charging frequency.

[0040] Optionally, in order to ensure a good sealing effect of the photovoltaic panel 101, prevent the photovoltaic panel 101 from being exposed to rain, and extend the service life of the photovoltaic panel 101, the photovoltaic power generation component 1 also includes a limiter 103, the top cover 102 is provided with a accommodating cavity, and an installation opening connected to the accommodating cavity, the photovoltaic panel 101 is arranged in the accommodating cavity, and the limiter 103 can open or close the installation opening.

[0041] In this embodiment, in order to facilitate the installation and removal of the photovoltaic panel 101, the photovoltaic power generation assembly 1 further includes a first guide rail 104 and a second guide rail 105. The first guide rail 104 and the second guide rail 105 are opposite to each other and are spaced apart from each other on the top cover 102. One side of the photovoltaic panel 101 can slide with the first guide rail 104, and the other side of the photovoltaic panel 101 can slide with the second guide rail 105. With this arrangement, the photovoltaic panel 101 can be installed at the center of the top cover 102 by using the first guide rail 104 and the second guide rail 105. The photovoltaic panel 101 is then fixed by closing the installation opening with the stopper 103. When the photovoltaic panel 101 needs to be removed, the stopper 103 is removed, and the photovoltaic panel 101 can be quickly removed and replaced by using the first guide rail 104 and the second guide rail 105.

[0042] Optionally, the commercial vehicle includes a cab, and the photovoltaic power generation assembly 1 is arranged directly above the cab.

[0043] Optionally, to further accommodate lightweight, curved surface installation scenarios, photovoltaic panels 101 can be made of a flexible material. This arrangement allows the flexible photovoltaic panels 101 to be placed within the housing cavity within the roof 102, allowing the cab to maintain its original streamlined shape and seal, ensuring ease and accuracy of installation. The flexible streamlined shape of the roof 102 also maintains the original cab's wind resistance. It should be noted that the entire vehicle body can be constructed using the flexible photovoltaic panels 101 structure, or replaced with a vehicle body material that automatically absorbs sunlight.

[0044] Optionally, the power supply control system includes an energy storage control unit 3 and an inverter 4. The energy storage control unit 3 is arranged above the right rear side of the vehicle body, and the energy storage control unit 3 includes a conversion controller and a battery. The input end of the conversion controller is connected to the photovoltaic panel 101, and the output end of the conversion controller is connected to the battery. The input end of the inverter 4 is connected to the battery, and the output end of the inverter 4 is connected to the vehicle body floor wiring harness 2.

[0045] Alternatively, the input of the conversion controller is connected to the photovoltaic panel 101, the output of the conversion controller is connected to the input of the inverter 4, and the output of the inverter 4 is connected to the vehicle floor harness 2. This configuration separates the power supply control system into a separate module, allowing the connection position with the vehicle floor harness 2 to be freely adjusted to suit different cabs, ensuring versatility and adaptability. Furthermore, the integrated configuration of the conversion controller and battery saves layout space and effectively improves vehicle installation space utilization.

[0046] Optionally, in order to improve the connection stability and reliability of the energy storage control unit 3, the commercial vehicle self-generating device further includes a first fixing bracket, which is fixedly connected between the energy storage control unit 3 and the vehicle body.

[0047] Optionally, in order to improve the connection stability and reliability of the inverter 4 , the commercial vehicle self-generating device further includes a second fixing bracket, which is fixedly connected to the inverter 4 and the vehicle body tool box.

[0048] Please refer to Figure 5 As shown, this embodiment also provides a commercial vehicle self-generation method, which is implemented by the commercial vehicle self-generation device in the above solution. The commercial vehicle self-generation method includes:

[0049] S100: Photovoltaic panel 101 receives sunlight and converts light energy into electrical energy;

[0050] S200: The conversion controller monitors the conversion current of the photovoltaic panel 101 in real time and controls the output power according to demand;

[0051] S300: The battery stores unused electrical energy when the vehicle's electrical equipment is not in operation;

[0052] S400: The inverter 4 receives the DC power converted by the photovoltaic panel 101 and converts it into AC power;

[0053] S500: The vehicle body floor wiring harness 2 transmits AC power to the vehicle's electrical equipment.

[0054] It should be noted that this method takes into account the particularity of the commercial vehicle circuit harness structure and does not directly connect the wires to the on-board electrical equipment. Instead, it adopts the method of docking with the vehicle body floor harness 2. The advantage of this wiring method is that it does not add new pin interfaces for on-board electrical equipment.
