Description

Technical Field

[0001] The present invention belongs to the technical field of transportation means, and particularly relates to an electric vehicle provided with a solar cell. Background Art

[0002] With the increasingly serious environmental pollution, only through environmental protection innovation can sustainable development be achieved. Nowadays, the development trend of automobiles has also shifted to new energy technologies of electrification. However, current electric vehicles use lithium batteries as the power source, and each full charge can only provide a cruising range of several hundred kilometers. Moreover, it is easily affected by factors such as driving habits and often fails to reach the nominal cruising range. At the same time, the construction of charging pile facilities lags behind, thus causing people to have "range anxiety" and worry about running out of power and breaking down. In order to increase the cruising range, some current electric vehicles use range extender engines to supplement electric energy to the battery pack to increase the cruising range, but this also causes problems of exhaust emissions.

[0003] In order to achieve zero-emission electric vehicles to promote environmental protection, the traditional thinking should be broken and the car shape should be redesigned to form a large area where solar cells can be set, replacing the range extender engine to supplement electric energy to the battery pack, achieving a certain cruising range in a short time, which can be used to find a charging pile to avoid running out of power and breaking down, solving the "range anxiety" problem. Moreover, the combination of the solar cell and the electric vehicle can utilize its battery pack to form a photovoltaic energy storage device, improving the practicality of the electric vehicle and further promoting environmental protection. Summary of the Invention

[0004] The purpose of the present invention is to solve the defects of the above-mentioned prior art, and provide an electric vehicle provided with a solar cell, which uses a solar cell to replace the range extender engine to achieve zero emission and solve the "range anxiety" problem, and forms a photovoltaic energy storage device by combining the electric vehicle and the solar cell to further promote environmental protection.

[0005] The technical solution of the present invention is: an electric vehicle provided with a solar cell, including an electric vehicle body and a solar cell provided on the electric vehicle. The electric vehicle is composed of a vehicle head and a carriage. The A-pillar is arranged in a forward inclination in the carriage, and a windshield is provided between the A-pillars on both sides of the vehicle body. The carriage roof is formed into an arc-shaped structure extended above the vehicle head to expand the interior space of the vehicle, and the area of the solar cell is increased to improve the power generation. The center to the periphery of the windshield is formed into a curved surface with different radian values, promoting the formation of a streamlined shape with the carriage roof and the vehicle body to reduce wind resistance.

[0006] Furthermore, the vehicle head and the carriage are fixedly connected through a trapezoidal frame, and their outer shells are independently arranged.

The electric vehicle charges through the solar cell or together with the retractable solar cell to increase the endurance, and constitutes a photovoltaic energy storage device to supply power to the outside.

[0007] Furthermore, the vehicle head is a low-profile streamline structure, and the overall lengthened size increases the area of the solar cell to improve the power generation. The left and right sides of the vehicle head are provided with fenders, which cover the lower end of the A-pillar and are connected to the outer shell of the carriage. The vehicle head cover is provided with a ventilation opening below the lower border of the windshield. A diversion channel is arranged inside the ventilation opening, which runs through the chassis and leads to the ground, promoting the flow of oncoming air and reducing wind resistance.

[0008] Furthermore, a front apron is provided below the windshield and is fixed on the trapezoidal frame. The middle part of the front apron forms a diversion channel that slopes forward, and its inclination is the same as or greater than that of the windshield. The left and right sides of the front apron protrude in the vehicle head to form a footrest area for the front row seats. A B-pillar and a C-pillar are arranged in the middle of the carriage. A pair of opening doors are arranged between the B-pillar and the C-pillar. The pair of opening doors are provided with a linkage switch to control the movement of the front row seats, constituting a seat welcome function. A rearview mirror and a reinforcing rib are arranged in the middle of the A-pillar. The reinforcing rib is fixedly connected to the middle of the B-pillar. A console is arranged between the reinforcing ribs on both sides of the vehicle body to connect the front apron, and the lower ends of the A-pillar and the B-pillar are merged and fixedly connected to the trapezoidal frame to jointly strengthen the structural stiffness of the carriage.

[0009] The beneficial effects of the present invention are as follows: The present invention adopts a forward-tilted A-pillar to form a large roof and is provided with a sandwich layer that can install more solar cells to supplement electric energy, solving the "endurance anxiety" problem of electric vehicles, and constituting a photovoltaic energy storage device to improve the practicality.

[0014] The following is a specific description in conjunction with the accompanying drawings in the embodiments of the present invention.

[0015] As Figure 1 shown, an electric vehicle equipped with a solar cell includes an electric vehicle body and solar cells disposed on the roof and the front hood of the electric vehicle. The electric vehicle is formed by integrally connecting a front end and a carriage through an air suspension to a trapezoidal vehicle 3, and the outer shells of the front end and the carriage are independently provided. The air suspension can lower the front end and raise the rear end, making the solar cell tilt towards the sun to improve the power generation efficiency. The front half of the front hood and the rear half of the roof of the carriage are respectively provided with a sandwich layer on the inner side, and a retractable solar cell 4 is provided in the sandwich layer. The retractable solar cell 4 can be manually pulled out by manpower when the electric vehicle is parked, and is fixed by support rods respectively disposed at the front end and the rear end of the vehicle. The support rods are of a telescopic rod structure, and the appropriate length is manually pulled out to adjust the tilt angle of the retractable solar cell 4 towards the sun for power generation. The solar cells on the front hood and the roof of the carriage together with the retractable solar cell 4 can increase the charging power. For example, for a medium and large-sized vehicle with a body length of 5 meters and a roof width of 1.6 meters, at least 10 square meters of solar cells can be provided on the roof plus the part extending above the front end of the vehicle. Plus, there are at least 5 square meters for the retractable solar cell 4. Referring to the photoelectric conversion efficiency of the solar cell being between 15% and 20%, therefore, the power generation per hour of 15 square meters of solar cells is about 2 - 3 kilowatts. Referring to the power consumption per 100 kilometers of the electric vehicle being between 15 - 20 kWh (under normal sunlight conditions, the solar cells on the roof are constantly charging, and the actual power consumption is lower than this reference value), it can provide a 10-km endurance for half an hour to find a charging pile to solve the "endurance anxiety" problem, or a photovoltaic energy storage device of 20 - 30 degrees of electricity can be formed according to the 10-hour sunlight condition throughout the day.

[0016] As Figure 1 、 Figure 2 shown, the front end is a streamlined structure with a low profile, and the overall lengthened size increases the area of the solar cell to improve the power generation. The front side is provided with an anti-collision beam connecting the trapezoidal frame 3, and the outer shells on both sides form fenders 6. The rear half of the fenders 6 covers the lower end of the A-pillar 1 of the carriage and is connected to the outer shell of the carriage. The front hood is provided with a ventilation opening below the lower border of the windshield 2, and a diversion channel 5 is provided inside the ventilation opening, which runs through the chassis to the ground to promote the oncoming air flow and reduce the wind resistance.

[0017] As Figure 1 、 Figure 2 、 Figure 3As shown in the figure, the carriage is tilted forward with an A-pillar 1. There is a windshield 2 between the A-pillars 1 on both sides of the vehicle body. The carriage roof is formed into an arc structure and extended above the vehicle head to expand the interior space, and the area of the solar panels is increased to improve power generation. The part of the carriage roof extending above the vehicle head has a certain height from the vehicle top cover to ensure a wide forward view. The center of the windshield 2 forms a curved surface with different curvatures from the center to the periphery, and is integrally connected with the carriage roof and the vehicle body on both sides to form a streamlined shape to promote wind resistance reduction. Below the windshield 2, there is a front apron fixed on the trapezoidal frame 3. The middle part of the front apron forms a diversion channel 5 that slopes forward, and its inclination is the same as that of the windshield 2. The left and right sides of the front apron protrude in front of the vehicle head to form the footrest area of the front row seats.

[0018] As Figure 1 , Figure 3 As shown in the figure, there is a B-pillar 7 and a C-pillar 8 in the middle of the carriage. There is a pair of opening doors between the B-pillar 7 and the C-pillar 8. Since the B-pillar 7 is arranged on the front edge of the front row seats, blocking the access for getting on and off the vehicle, the seat can only be moved backward close to the door to open the passage. To improve convenience, the pair of opening doors is provided with a linkage switch to control the movement of the front row seats. When the pair of opening doors is opened and closed, the linkage switch automatically controls the forward and backward movement of the seats to form a seat welcome function. In the middle of the A-pillar 1, there are left and right rearview mirrors and a reinforcing rib 9. The other end of the reinforcing rib 9 is connected to the middle of the B-pillar 7. There is a center console connecting the front apron between the reinforcing ribs 9 on both sides of the vehicle body, and the lower end of the A-pillar 1 and the lower end of the B-pillar 7 are combined and fixedly connected to the trapezoidal frame 3 to jointly strengthen the structural stiffness of the carriage.

[0019] The above are only embodiments of the present invention. The protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention.
