Description

Technical Field

[0001] This utility model relates to the field of electric vehicles, specifically to an electric vehicle with a curved photovoltaic roof. Background Technology

[0002] With the continuous improvement of rural roads and the gradual increase in farmers' income, electric tricycles and four-wheeled vehicles are increasingly appearing in people's lives due to their advantages of being environmentally friendly, energy-saving, convenient, and practical. Photovoltaic new energy tricycles are a new type of transportation that utilizes solar photovoltaic technology. They can collect solar energy through solar panels, convert it into electricity, and drive the vehicle.

[0003] Chinese utility model patent CN211942981U discloses a solar-powered electric tricycle. The tricycle includes a body with a driver's cab at the front and a cargo box at the rear. The cargo box has a front support column at the front and a retractable rear support column at the rear. A first sunshade is installed on the top of the cargo box, and a second sunshade is installed on the top of the driver's cab. Solar photovoltaic panels are fixedly installed on the first sunshade. However, in actual use, it has been found that installing the photovoltaic panels on the top of the cargo box disrupts the overall design of the vehicle, affecting aesthetics and energy consumption. There is also a risk of the photovoltaic panels falling off due to insecure installation or in the event of an accident.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of photovoltaic panels being mounted on the roof of a vehicle via supports, affecting the vehicle's aesthetics and energy consumption, this utility model provides an electric vehicle with a curved photovoltaic roof. The electric vehicle with a curved photovoltaic roof includes: a frame, on which a windshield is mounted, and a battery is mounted at the bottom of the frame; a roof, mounted on the frame; the roof includes a curved glass forming a sealed connection with the frame, and a photovoltaic panel fixedly mounted below the curved glass; the curved glass is in contact with the windshield; the photovoltaic panel is electrically connected to the battery, and a power-off controller is provided between the photovoltaic panel and the battery.

[0006] This invention relates to an electric vehicle with a curved photovoltaic roof, comprising a frame and a roof. The frame is used to mount various structures. The roof includes curved glass and photovoltaic panels. The curved glass serves as the roof and connects to the windshield, ensuring the vehicle maintains a streamlined overall shape, reducing wind resistance, and enhancing the vehicle's aesthetics and practicality. The photovoltaic panels are positioned below the curved glass, protecting them and reducing the probability of them detaching. The photovoltaic panels are electrically connected to a battery, converting solar energy into electrical energy, which is stored within the battery. A power-off controller protects the battery, improving the safety and stability of the photovoltaic system. Through these features, this invention, an electric vehicle with a curved photovoltaic roof, replaces the traditional roof with curved glass that connects to the windshield, ensuring the vehicle maintains a streamlined overall shape, enhancing its aesthetics and practicality; placing the photovoltaic panels below the curved glass protects them, strengthens the overall structural integrity of the vehicle, and reduces the probability of accidents.

[0007] Furthermore, the vehicle frame includes a first side frame and a second side frame arranged opposite to each other, and a first support plate for supporting the curved glass is fixed on the first side frame and the second side frame. Through the above arrangement, the arrangement of the first support plate facilitates the installation of the curved glass on the vehicle frame, ensuring the connection stability between the vehicle frame and the curved glass.

[0008] Furthermore, the vehicle frame also includes a first connecting beam connecting the first side frame and the second side frame; the first connecting beam supports the curved glass, and a second support plate supporting the windshield is provided on the first connecting beam. Through the above arrangement, the first connecting beam and the second support plate facilitate the connection between the windshield and the curved glass, ensuring a streamlined body shape, reducing wind resistance, and enhancing aesthetics and practicality.

[0009] Furthermore, the curved glass includes an arcuate portion that abuts against the first connecting beam and an arcuate portion that abuts against the first support plate; the arcuate portion is in contact with the windshield.

[0010] Furthermore, the angle range of the arc-shaped surface is 42°-46°; the angle range of the curved surface is 8°-10°.

[0011] Furthermore, a second connecting beam supporting the curved glass is provided between the first side frame and the second side frame. Through this arrangement, the second connecting beam enhances the structural strength of the vehicle frame and supports the curved glass, thereby improving the overall structural stability of the vehicle.

[0012] Furthermore, a rear wing is fixed to the vehicle frame, and a support platform for supporting the curved glass is recessed in the rear wing. Through the above configuration, the rear wing can further create a streamlined vehicle body, enhancing both aesthetics and practicality; the support platform facilitates the installation and fixation of the curved glass.

Exemplarily, the first support plate 16 is generally L-shaped, with one arm fixed to the first side frame 11 and the second side frame 12 by welding, and the other arm extending horizontally to support the curved glass. Furthermore, a first connecting beam 17 is provided between the first side frame 11 and the second side frame 12, and the first connecting beam 17 is arranged at the forward and downward bend of the first side frame 11 and the second side frame 12. Specifically, a second support plate 19 is fixed in front of the first connecting beam 17.

Furthermore, a rear spoiler 3 is fixed at the rear of the frame 1, and a support platform 31 for supporting the curved glass is recessed in the rear spoiler 3.

[0029] Figure 4 This is a schematic diagram of an embodiment of the roof of an electric vehicle with a curved photovoltaic roof according to the present invention. Figure 4 In the image, the top view is the front view of roof 2, and the bottom view is the left view of roof 2. (See image below.) Figure 1 , Figure 2 and Figure 4 As shown, the roof 2 and the base are arranged opposite to each other. In one or more embodiments, the roof 2 includes curved glass that forms a sealed connection with the frame 1, and a photovoltaic panel fixedly installed below the curved glass. Specifically, the thickness of the curved glass is approximately 5 mm, and the thickness of the photovoltaic panel is approximately 1 mm. The photovoltaic panel is fixed to the underside of the curved glass by adhesive bonding. Furthermore, a wire connected to the battery 5 is provided on the photovoltaic panel to store the electrical energy converted by the photovoltaic panel into the battery 5. Specifically, two wires are provided and arranged diagonally on the photovoltaic panel. A power-off controller 6 is provided between the photovoltaic panel and the battery 5, and the wires extend from the photovoltaic panel to the power-off controller 6 and then from the power-off controller 6 to the battery 5.

Specifically, the angle range of the curved surface 21 is 42°-46°, and the angle range of the curved surface 22 is 8°-10°. It is understandable that, compared to flat glass, curved glass is more prone to breakage during manufacturing due to angle issues, making it difficult to produce finished products. Through stress analysis and actual experiments, it has been found that when the angle of the curved glass is within the above range, its stability is better, it is less prone to breakage, and the yield is higher. For example, the angle of the curved surface 21 is 44°, and the angle of the curved surface 22 is 9°. The total length of the curved glass is 1100mm, and the maximum width is 920mm. The angle range of the curved surface 21 refers to its downward and forward curvature. The angle range of the curved surface 22 refers to its upward convex curvature. The center of the curved surface 22 convexes upward, with an angle of 9° in the left-right direction and also 9° in the front-back direction.
