DETAILED DESCRIPTION OF THE INVENTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-8 As shown, this embodiment provides a solar car cover, which includes a mounting plate 1. The mounting plate 1 is detachably mounted on the frame at the top of the vehicle. A protection box 2 is mounted on the top of the mounting plate 1. A storage cavity is opened at the bottom of the protection box 2. The mounting plate 1 can block the opening of the storage cavity at the bottom of the protection box 2, making the storage cavity a relatively closed storage space. In actual design, both the mounting plate 1 and the protection box 2 are provided with rounded corners. At the same time, a soft protection pad is connected to the bottom of the protection box 2; two electric push rods 3 for driving the protection box 2 to lift and lower on the mounting plate 1 are mounted on the mounting plate 1. The two electric push rods 3 are mounted at the middle positions on both sides of the top of the mounting plate 1. When driving the protection box 2 to lift and lower, the stability of the protection box 2 during lifting and lowering can be ensured. A winding shaft 4 is rotatably mounted between the mounting plate 1 and the protection box 2. A motor 21 is fixedly mounted at the bottom of the mounting plate 1. A wire is connected between the motor 21 and the battery on the vehicle. The output shaft of the motor 21 passes through the mounting plate 1 and is fixedly connected to the bottom end of the winding shaft 4.

[0031] A sleeve 5 is sleeved on the winding shaft 4. A flexible solar car cover structure is sleeved on the sleeve 5. The flexible solar car cover structure is a cloth-like structure that can cover the vehicle. The flexible solar car cover structure includes a protection cloth 7 and a flexible solar panel car cover 8. The flexible solar panel car cover 8 is formed by splicing multiple small-area solar panels, forming a structure such as Figure 5 、 Figure 6The grid shape shown has the grid printed in a radially diffused pattern; when winding, the flexible solar panel car cover 8 can be folded along the imprint at the splicing joint for winding, which plays a protective role for the flexible solar panel car cover 8; the inner circle of the protective cloth 7 is fixedly connected to the outer circumference of the ferrule 5. In actual operation, when the entire flexible solar car cover structure is wound around the winding shaft 4, the deeper the crease is at the position closer to the inner circle of the winding shaft 4, and this position is more likely to be damaged. By setting the protective cloth 7 at the innermost circle position, the damage caused by the crease of the cloth to the cloth is very small, which can reduce the situation where the flexible solar panel car cover 8 is damaged due to too deep creases. The outer circumference of the protective cloth 7 is sewn to the inner circle of the flexible solar panel car cover 8; there is an electric wire connected between the flexible solar panel car cover 8 and the automotive battery. The flexible solar car cover structure also includes an elastic collar 9, and the elastic collar 9 is also made of cloth, with a rubber band sewn to the outermost circle; the inner circle of the elastic collar 9 is sewn to the outer circumference of the flexible solar panel car cover 8. The elastic collar 9 is directly looped around the vertical surface at the bottom of the car. Due to the elastic effect of the elastic collar 9, it is buckled at the bottom of the vehicle, thus ensuring the stability of the entire flexible solar car cover structure and reducing the situation of being blown up by the wind; the flexible solar car cover structure can be wound around the winding shaft 4 and stored in the storage cavity, and the flexible solar car cover structure can also cover the vehicle.

[0032] It should be noted that the mounting plate 1 is located below the protective box 2, which can ensure that when the flexible solar car cover structure is stored or unfolded, it will not rub against the inner wall of the opening of the storage cavity of the protective box 2, reducing the damage caused by rubbing.

[0033] When opening the entire flexible solar car cover structure, in actual operation, first the electric push rod 3 works to drive the protective box 2 to rise, so that there is a gap between the bottom of the protective box 2 and the top surface of the mounting plate 1. Then the motor 21 works to drive the winding shaft 4 to rotate, and the flexible solar car cover structure wound around the winding shaft 4 is unfolded. When the wound flexible solar car cover structure is unfolded, it will spread out and leak through the gap between the protective box 2 and the mounting plate 1. The vehicle owner can grab the flexible solar car cover structure leaking out of the storage cavity and unfold it, and cover the flexible solar car cover structure on the vehicle.

[0034] When winding the entire flexible solar car cover structure, the motor 21 can work to drive the winding shaft 4 to rotate, and wind the entire flexible solar car cover structure around the winding shaft 4 (first the protective cloth 7 is wound around the winding shaft 4, where the crease is the deepest, then the middle flexible solar panel car cover 8 is wound up, and finally the elastic collar 9 is wound up), and store it in the storage cavity. Then the electric push rod 3 works to drive the protective box 2 to descend to cover the wound flexible solar car cover structure in the storage cavity for protection and storage.

[0035] Such asFigure 5 , Figure 6 As shown in Figure 6 , a slit is provided in the flexible solar car cover structure. The position of the slit is on both sides of the vehicle. The slit is used to avoid the electric push rod 3. A zipper is sewn at the slit. The electric push rod 3 can be placed in the slits on both sides of the flexible solar car cover structure, and then the slit is zipped up, so that the flexible solar car cover structure can completely cover the vehicle.

[0036] A first rigid solar panel 6 is fixedly installed on the top of the protection box 2. In practice, the conversion efficiency of the first rigid solar panel 6 on the top of the protection box 2 is higher than that of the flexible solar panel, and the area on the top of the protection box 2 can be fully utilized.

[0037] Receiving grooves are provided on both sides of the protection box 2, and the receiving grooves are not communicated with the storage cavity; a second rigid solar panel 10 is slidably installed in the receiving groove, and an electric wire is also connected between the second rigid solar panel 10 and the vehicle battery; a transmission structure is provided between the winding shaft 4 and the second rigid solar panel 10; when the winding shaft 4 rotates, the second rigid solar panel 10 is driven to extend and retract in the receiving groove through the transmission structure. When the winding shaft 4 unfolds the flexible solar car cover structure, the rotational movement of the winding shaft 4 is transmitted to the second rigid solar panel 10 to extend out of the receiving groove through the transmission structure, and solar power generation can be carried out; when the winding shaft 4 winds up the flexible solar car cover structure, the winding shaft 4 rotates in the reverse direction and drives the second rigid solar panel 10 to be received into the receiving groove through the transmission structure, playing a role in protecting and storing the second rigid solar panel 10.

[0038] The transmission structure includes a drive shaft 11, a main gear 12, a transmission gear 13, an internal gear 14, a swing rod 15 and a lifting connection assembly; a working cavity is formed in the protection box 2, and the drive shaft 11, the main gear 12, the transmission gear 13 and the internal gear 14 are all located in the working cavity. The drive shaft 11 is rotatably installed in the protection box 2. The bottom end of the drive shaft 11 is axially connected to the winding shaft 4 through the lifting connection assembly, and the drive shaft 11 can move up and down at the top end of the winding shaft 4 through the lifting connection assembly; the main gear 12 is sleeved on the drive shaft 11, the transmission gear 13 is rotatably installed in the protection box 2, and the transmission gear 13 meshes with the main gear 12. The internal gear 14 is rotatably installed in the protection box 2, and the inner ring of the internal gear 14 meshes with the transmission gear 13. The number of swing rods 15 is two, and the two swing rods 15 are symmetrically connected to the outer periphery of the internal gear 14. One ends of the two swing rods 15 away from the internal gear 14 are respectively slidably connected to one side of the second rigid solar panel 10; a sliding shaft 16 is fixedly connected to the end of the swing rod 15, and a linear sliding groove 17 that slidably cooperates with the sliding shaft 16 is formed in the second rigid solar panel 10; when the winding shaft 4 rotates, the winding shaft 4 drives the lifting connection assembly and the drive shaft 11 to rotate synchronously, and then the drive shaft 11 drives the main gear 12 to rotate, and then the main gear 12 drives the transmission gear 13 to rotate, and then the transmission gear 13 drives the internal gear 14 to rotate in the working cavity. The rotating internal gear 14 drives the two swing rods 15 to swing. When the swing rod 15 swings, since the end of the swing rod 15 is slidably fitted with the side surface of the second rigid solar panel 10 through the sliding shaft 16, the sliding shaft 16 drives the second rigid solar panel 10 to perform telescopic movement in the storage groove, so as to control the position of the second rigid solar panel 10; in actual use, when the winding shaft 4 releases or winds up the flexible solar car cover structure, it needs to rotate multiple circles to complete. However, the second rigid solar panel 10 can be ejected from the storage groove only by rotating the swing rod 15 by 90°. Through the rotational speed reduction of the main gear 12, the transmission gear 13 and the internal gear 14, there is a speed difference between the rotational speed of the internal gear 14 and the rotational speed of the winding shaft 4, so that the internal gear 14 needs to rotate multiple circles to make the internal gear 14 rotate 90°, thereby ensuring the speed of the second rigid solar panel 10 when extending or retracting into the storage groove and ensuring the stability of the movement of the second rigid solar panel 10.

[0039] The lifting connection assembly includes a telescopic rod 18 and a hexagonal block 19; one end of the telescopic rod 18 is fixedly connected to the bottom end of the driving shaft 11, and a telescopic hole that slides with the telescopic rod 18 is opened at the top of the winding shaft 4. The hexagonal block 19 is fixedly connected to the bottom end of the telescopic rod 18. The winding shaft 4 is provided with a hexagonal slide that slides with the hexagonal block 19. A spring 20 is arranged on the telescopic rod 18 in the hexagonal slide. The two ends of the spring 20 respectively abut against the top surface of the hexagonal block 19 and the top inner wall of the hexagonal slide. When the electric push rod 3 pushes the protective box 2 to rise or fall, the hexagonal block 19 can be lifted and lowered in the hexagonal slide. At the same time, the telescopic rod 18 connects the hexagonal block 19 and the driving shaft 11 to ensure that the telescopic rod 18 will not detach from the top of the winding shaft 4, thereby ensuring the normal lifting operation of the protective box 2.

[0040] When the No. 2 rigid solar panel 10 is extended out of the storage slot, the projection of the two No. 2 rigid solar panels 10 and the protective box 2 on the ground coincides with the projection of the protective cloth 7 on the ground when it is unfolded. In actual use, when the No. 2 rigid solar panel 10 is extended out of the storage slot, the sun directly shines on the No. 1 rigid solar panel 6, the two No. 2 rigid solar panels 10 and the flexible solar panel cover 8, thereby reasonably utilizing the space and better ensuring the conversion efficiency of solar energy.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
