Technical Field

[0001] This utility model belongs to the technical field of electric vehicles, and relates to a photovoltaic range extender system for electric vehicles and an electric vehicle. Background Technology

[0002] As a green mode of transportation, the driving range of electric vehicles has always been a core concern for users. Currently, the main ways to increase driving range are to increase battery capacity or build more charging stations, but both methods have limitations such as high cost and large infrastructure investment. Solar energy, as a clean and readily available energy source, has been explored for application in the electric vehicle field, for example, by fixing solar panels to the vehicle body. However, traditional rigid solar panels have problems such as being heavy, inflexible, affecting the aesthetics of the vehicle, and being easily damaged. On the other hand, directly laying flexible solar panels has problems such as not being able to store them when not in use, being prone to aging due to long-term exposure to sun and rain, and being easily stolen or damaged while in use.

[0003] Chinese utility model patent CN208264453U (publication date: 2018-12-21) discloses a solar-powered electric vehicle, including an electric vehicle body. A battery box is located inside the bottom of the electric vehicle body, and a storage box is slidably installed inside the battery box. A storage box is located on one side of the top of the electric vehicle body. From left to right, a first electric telescopic rod, a photovoltaic inverter, a PLC controller, and a second electric telescopic rod are sequentially installed inside the bottom of the storage box. A rectangular frame is fixedly installed at the top output end of the first and second electric telescopic rods. A photovoltaic power generation panel is located inside the rectangular frame. The rectangular frame is rotatably connected to a rotating shaft that passes through the interior of the photovoltaic panel. A motor is welded to the top of the rectangular frame. The output shaft of the motor is connected to the internal input shaft of the reducer. The output shaft of the reducer is meshed with the top of the rotating shaft. A photoelectric sensor is fixedly installed on one side of the top of the rectangular frame. The output end of the photovoltaic panel is electrically connected to the input end of the battery and the photovoltaic inverter via wires. The output ends of the photoelectric sensor, the battery, and the photovoltaic inverter are electrically connected to the input end of the PLC controller via wires. The output end of the PLC controller is electrically connected to the input ends of the motor and the electric vehicle body via wires respectively.

[0004] The aforementioned solar-powered electric vehicles are complex, costly, and space-consuming, requiring dedicated storage space. Furthermore, the additional mechanical structure reduces the overall reliability of the vehicle. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a photovoltaic range extender system and electric vehicle, which can effectively utilize parking time to generate photovoltaic power and extend the driving range of electric vehicles.

[0006] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution: A photovoltaic range extender system for an electric vehicle includes a seat bucket and a seat cushion hinged to the rear of the seat bucket. The seat bucket contains a battery compartment for installing a rechargeable battery. The rechargeable battery is electrically connected to a photovoltaic module via a photovoltaic controller. The photovoltaic module includes a flexible solar panel. The seat bucket contains a storage box for storing the flexible solar panel. The flexible solar panel is wound on a spool in the storage box. A traction member is provided at the free end of the flexible solar panel. The traction member can pull the flexible solar panel out of the storage box and lay it flat to cover the upper surface of the seat cushion. After being laid, the flexible solar panel is fixed to the seat cushion by the traction member.

[0007] In the aforementioned photovoltaic range extender system for an electric vehicle, the traction component is an elastic pull ring, which is used to fix a flexible solar panel by being fitted onto the rear end of the seat cushion.

[0008] Alternatively, in one of the photovoltaic range extender systems for electric vehicles described above, the traction component consists of two or more elastic pull ropes, the ends of which are provided with hooks that are hooked onto the bottom of the seat or onto the frame on both sides of the seat.

[0009] In the aforementioned photovoltaic range extender system for an electric vehicle, the storage box is located at the front of the battery compartment, and the photovoltaic controller is fixedly installed inside the storage box. The input terminal of the photovoltaic controller is electrically connected to the power output terminal of the flexible solar panel via a wire, and its output terminal passes through the storage box via a wire and is electrically connected to the power input terminal of the rechargeable battery, thus forming a charging circuit.

[0010] In the aforementioned photovoltaic range extender system for an electric vehicle, the fixed end of the flexible solar panel is connected to a reel via a flexible connector. During storage, the flexible connector and the flexible solar panel are wound sequentially onto the reel. Preferably, the length of the flexible connector is configured such that when the flexible solar panel is fully extended, the flexible connector still has spare length.

[0011] In the aforementioned photovoltaic range extender system for an electric vehicle, a notch is provided at the bottom front end of the seat cushion. When the seat cushion is fastened and locked, the flexible connector is accommodated within the notch to avoid interfering with the normal locking of the seat cushion.

[0012] Another objective of this invention is to provide an electric vehicle equipped with any of the aforementioned photovoltaic range extender systems.

[0013] Compared with the prior art, this utility model has the following advantages: This invention provides a photovoltaic range extender system for electric vehicles. It cleverly utilizes the surface area of ​​the seat exposed to sunlight when the vehicle is parked to install photovoltaic panels, converting solar energy into electrical energy for storage, effectively extending the driving range and making full use of idle resources. Furthermore, the design of the roll and storage box allows the flexible solar panels to be easily pulled out and retracted like a measuring tape, simplifying operation and solving the problem of daily storage and carrying of flexible solar panels. Moreover, the entire system is integrated inside the seat compartment, requiring no additional space in the vehicle and maintaining the original structure and aesthetics of the electric vehicle.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-3 : A photovoltaic range extender system for an electric vehicle includes a seat bucket 1 and a seat cushion 2 hinged to the rear side of the seat bucket 1. The seat bucket 1 has a battery compartment 3 for installing a rechargeable battery. The rechargeable battery is electrically connected to a photovoltaic module via a photovoltaic controller 4. The photovoltaic module includes a flexible solar panel 5. The seat bucket 1 has a storage box 6 for storing the flexible solar panel 5. The flexible solar panel 5 is wound on a roller 7 of the storage box 6. The free end of the flexible solar panel 5 is provided with a traction member 8. The traction member 8 can pull the flexible solar panel 5 out of the storage box 6 and lay it flat to cover the upper surface of the seat cushion 2. After being laid, the flexible solar panel 5 is fixed to the seat cushion 2 by the traction member 8.

[0016] This embodiment integrates a photovoltaic range extender system into a traditional electric vehicle. When not in use, the flexible solar panel 5 is completely retracted into the storage box 6 within the seat compartment 1, thus not interfering with the rider and maintaining the original appearance and handling of the electric vehicle. When charging is needed, the user parks the electric vehicle in a sunny location, flips up the seat cushion 2, and uses the traction component 8 located at the free end of the flexible solar panel 5 to pull it completely out of the storage box 6. The seat cushion 2 is then re-fastened and locked. Next, the pulled-out flexible solar panel 5 is laid flat on the upper surface of the seat cushion 2 to ensure it receives ample sunlight, and is secured to the seat cushion 2 using the traction component 8 or indirectly via the vehicle body. Photovoltaic charging then begins. The photovoltaic charging process in this embodiment is the same as in existing technologies; this photovoltaic range extender system utilizes parking time to assist in charging the battery. Calculations show that under typical sunlight conditions, the daily electricity generated can provide the electric vehicle with approximately 3 kilometers of additional range. While the range-extending effect is limited, it effectively alleviates users' range anxiety, especially suitable for solving the "last mile" travel problem. In addition, the flexible solar panel 5 laid on the surface of the seat cushion 2 also functions as a sunshade, preventing direct sunlight and thus protecting the surface of the leather or plastic seat cushion 2, effectively delaying its aging, fading and cracking caused by ultraviolet radiation.

[0017] In this embodiment, referring to the attached... Figure 1 The traction component 8 is an elastic pull ring, which fixes the flexible solar panel 5 by being fitted onto the rear end of the seat cushion 2. The flexible solar panel 5 can be easily pulled out by the elastic pull ring, and at the same time, the elastic pull ring can also be fitted into the rear end of the seat cushion 2 by its elasticity, thereby fixing the flexible solar panel 5.

[0018] Furthermore, refer to the appendix Figure 3 The storage box 6 is located on the front side of the battery compartment 3. The photovoltaic controller 4 is fixedly installed inside the storage box 6. The input end of the photovoltaic controller 4 is electrically connected to the power output end of the flexible solar panel 5 through a wire. Its output end passes through the storage box 6 through a wire and is electrically connected to the power input end of the rechargeable battery to form a charging circuit.

[0019] Preferred, see attached Figure 2 The fixed end of the flexible solar panel 5 is connected to the roller 7 via a flexible connector 9. When stored, the flexible connector 9 and the flexible solar panel 5 are wound sequentially onto the roller 7. Preferably, the length of the flexible connector 9 is configured such that when the flexible solar panel 5 is fully pulled out, the flexible connector 9 still has a spare length, that is, the length of the flexible connector 9 is much longer than the stroke required for the flexible solar panel 5 to be fully unfolded.

[0020] Preferably, the bottom front end of the seat cushion 2 is provided with a notch 10. When the seat cushion 2 is fastened and locked, the flexible connector 9 is accommodated in the notch 10 to avoid interfering with the normal locking of the seat cushion 2.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
