Description

Technical Field

[0001] This application relates to the field of photovoltaic system technology, and more specifically, to a vehicle-mounted photovoltaic system. Background Technology

[0002] Currently, traditional vehicle air conditioning systems rely on the car engine to drive the compressor or directly consume the vehicle battery's power. When the car is parked, if the air conditioning needs to be used, it usually requires starting the engine (resulting in energy waste and exhaust pollution) or directly using the vehicle battery's power (which can easily lead to battery depletion and affect the car's starting).

[0003] With the development of new energy vehicles, the energy consumption problem of parking air conditioners has become more prominent. In the existing technology of solar-powered vehicle air conditioning systems, rigid solar panels that are fixedly installed on the roof are mostly used. These panels have problems such as complicated installation, affecting the appearance of the vehicle, easy theft, and inconvenient folding and storage, making them difficult to widely apply. Summary of the Invention

[0004] In view of this, this application provides a vehicle-mounted photovoltaic system to solve the technical problems of complex installation and poor anti-theft performance in existing solar vehicle-mounted air conditioning systems that use rigid solar panels.

The flexible solar cell unit can be detachably fixed to at least one of the following locations: the inside of the front windshield, the inside of the rear windshield, and the inside of the side door windows of the vehicle. The flexible solar cell unit, the energy storage unit, and the vehicle air conditioning module are all electrically connected to the control unit.

[0006] Furthermore, the number of flexible solar cell units is four. The four flexible solar cell units are respectively arranged on the inside of the front windshield, the inside of the rear windshield, and both sides of the width direction of the vehicle interior. The flexible solar cell units arranged on both sides of the width direction of the vehicle interior cover the entire windshield on the corresponding side of the width direction of the vehicle interior.

[0010] Furthermore, the fixing structure is a buckle that can engage with the inner structure of the vehicle; or, the fixing structure is a vacuum suction cup that can adhere to the windshield and rear windshield of the vehicle.

[0011] Furthermore, the vehicle-mounted photovoltaic system includes multiple sets of bending and shaping components arranged sequentially at intervals along the length direction of the flexible solar cell unit. Each set of bending and shaping components includes a first bending and shaping structure and a second bending and shaping structure. The first bending and shaping structure and the second bending and shaping structure are located at the edge of the flexible solar cell unit in the width direction and are respectively connected to both sides of the flexible solar cell unit in the thickness direction. The first bending and shaping structure and the second bending and shaping structure can be bent at an equal angle toward the side of the second bending and shaping structure away from the first bending and shaping structure and fixed in a bent state, so that the position of the flexible solar cell unit corresponding to the first bending and shaping structure is bent and shaped toward the side of the second bending and shaping structure away from the first bending and shaping structure.

[0012] Furthermore, each set of bending and shaping components includes a multi-stage telescopic rod connected to the second bending and shaping structure. The multi-stage telescopic rod is capable of telescopic movement. One end of the multi-stage telescopic rod is connected to the second bending and shaping structure.

[0013] Further, the first bending and shaping structure includes a first connecting block and a second connecting block hinged to each other via a first hinge axis, and the second bending and shaping structure includes a third connecting block and a fourth connecting block hinged to each other via a second hinge axis. The first hinge axis and the second hinge axis are parallel to each other, and the axes of the first hinge axis and the second hinge axis are both aligned with the width direction of the flexible solar cell unit. The first connecting block and the second connecting block are both connected to one side of the thickness direction of the flexible solar cell unit, and the third connecting block and the fourth connecting block are connected to the other side of the thickness direction of the flexible solar cell unit. The bending and shaping assembly also includes a first movable locking rod, a second movable locking rod, a first locking screw, and a second locking screw. The first movable locking rod has a bidirectional through-hole along the width direction of the flexible solar cell unit. The first threaded hole and the second movable locking rod have a second threaded hole that extends bidirectionally along the width direction of the flexible solar cell unit. One end of the first movable locking rod is rotatably connected to the first connecting block via a first rotating shaft, and one end of the second movable locking rod is rotatably connected to the second connecting block via a second rotating shaft. Both the first and second rotating shafts are parallel to the first hinge shaft. The end face of the third connecting block has a first locking groove, and the end face of the fourth connecting block has a second locking groove. Both the first and second locking grooves extend along the length direction of the flexible solar cell unit. The first locking screw can pass through the first threaded hole and be pressed and locked at any position in the first locking groove, and the second locking screw can pass through the second threaded hole and be pressed and locked at any position in the second locking groove.

[0014] Furthermore, the flexible solar cell unit is a perovskite flexible thin-film battery.
