Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0031] Please see Figure 1-6 A portable solar cell module includes a base plate 1 with casters 22 at each of the four corners of its lower surface. A support plate 2 is fixedly connected to the upper surface of the base plate 1. A rotating plate 3 is rotatably connected to the inner wall of the support plate 2 via an angle adjustment mechanism. Battery modules are mounted on both sides of the rotating plate 3. The battery modules include:

[0032] The first photovoltaic panel 4 has a first connecting shaft 6 fixedly connected to the side of the front and rear ends of the first photovoltaic panel 4 that is close to the rotating plate 3. The first photovoltaic panel 4 is rotatably connected to the rotating plate 3 through the first connecting shaft 6. The side of the front and rear ends of the first photovoltaic panel 4 that is far away from the rotating plate 3 is fixedly connected to the second connecting shaft 8.

[0033] The second photovoltaic panel 5 has a third connecting shaft 10 fixedly connected to both the front and rear ends of the second photovoltaic panel 5 on the side closest to the first photovoltaic panel 4.

[0034] L-shaped rod 9, which is rotatably connected to the outer wall of the second connecting shaft 8 and the third connecting shaft 10 on the front side;

[0035] The first connecting rod 7 is rotatably connected to the outer wall of the rotating plate 3, and the other end of the first connecting rod 7 is rotatably connected to the L-shaped rod 9.

[0036] The first gear 11 is fixedly connected to the outer wall of the rear second coupling 8;

[0037] The second gear 12 is fixedly connected to the outer wall of the rear third shaft 10, and the first gear 11 and the second gear 12 are meshed together.

[0038] In this embodiment: the first photovoltaic panel 4 rotates downward along the first connecting shaft 6, and the first photovoltaic panel 4 further drives the second photovoltaic panel 5 to rotate upward along the second connecting shaft 8 through the L-shaped rod 9 and the first connecting rod 7. While the first photovoltaic panel 4 rotates downward, the first gear 11 and the second gear 12 further drive the second photovoltaic panel 5 to rotate upward along the third connecting shaft 10, thereby folding the first photovoltaic panel 4 and the second photovoltaic panel 5, reducing the space occupied, and making it easy to carry.

[0039] As a technical optimization of this utility model, the front ends of the two first connecting shafts 6 on the front side extend to the outside of the rotating plate 3 and are fixedly connected to the third gear 13. The front end face of the rotating plate 3 is rotatably connected to the first threaded rod 14 through the ear plate. The outer wall of the first threaded rod 14 is threadedly connected to the first slider 15. The left and right end faces of the first slider 15 are fixedly connected to the first straight rack 16. The two first straight racks 16 are respectively meshed with the two third gears 13.

[0040] In this embodiment: Rotating the first threaded rod 14 causes the first slider 15 to move upward, which in turn causes the two first straight racks 16 to move upward. The first straight racks 16 further drive the third gear 13 to rotate, which in turn drives the first connecting shaft 6 to rotate, thereby causing the first photovoltaic panel 4 to rotate downward, making it easier to fold the first photovoltaic panel 4 and the second photovoltaic panel 5. Reversely rotating the first threaded rod 14 causes the first slider 15 to move downward, thereby causing the first photovoltaic panel 4 to rotate upward, making it easier to unfold the first photovoltaic panel 4 and the second photovoltaic panel 5.

[0041] As a technical optimization of this utility model, the angle adjustment mechanism includes two fourth shafts 17 fixedly connected to the front and rear end faces of the rotating plate 3. The front end of the fourth shaft 17 extends to the outside of the support plate 2 and is fixedly connected to a fourth gear 18. The front end face of the support plate 2 is rotatably connected to a second threaded rod 19 through an ear plate. The outer wall of the second threaded rod 19 is threadedly connected to a second slider 20. The outer wall of the second slider 20 is fixedly connected to a second spur rack 21 that meshes with the fourth gear 18.

[0042] In this embodiment: rotating the second threaded rod 19 causes the second slider 20 to move up and down, which in turn causes the second rack 21 to move up and down. The second rack 21 further drives the fourth gear 18 to rotate, which in turn drives the rotating plate 3 to rotate, thereby adjusting the angle of the battery assembly. This method is highly practical.

[0043] As a technical optimization of this utility model, the outer wall of the base plate 1 is connected by four symmetrically distributed threaded nails 23.

[0044] In this embodiment: rotating the threaded nail 23 causes the threaded nail 23 to drill downwards into the ground, thereby facilitating the fixing of the base plate 1 and thus fixing the device to the ground.

[0045] As a technical optimization of this utility model, the rear end face of the first slider 15 abuts against the front end face of the rotating plate 3.

[0046] In this embodiment: by abutting the rear end face of the first slider 15 against the front end face of the rotating plate 3, the first slider 15 is easily limited and prevented from rotating.

[0047] As a technical optimization of this utility model, the rear end face of the second slider 20 abuts against the front end face of the support plate 2.

[0048] In this embodiment: by abutting the rear end face of the second slider 20 against the front end face of the support plate 2, the second slider 20 is easily limited and prevented from rotating.

[0049] As a technical optimization of this utility model, a second connecting rod 24 is rotatably connected to the outer wall of the second connecting shaft 8 and the third connecting shaft 10 located on the rear side.

[0050] In this embodiment, the second connecting rod 24 facilitates the rear connection and limiting of the first photovoltaic panel 4 and the second photovoltaic panel 5, thereby stabilizing the rotation of the second photovoltaic panel 5.

[0051] The working principle and usage process of this utility model are as follows: During the folding process, rotating the first threaded rod 14 causes the first slider 15 to move upward, which in turn causes the two first straight racks 16 to move upward. The first straight racks 16 further drive the third gear 13 to rotate, which in turn drives the first connecting shaft 6 to rotate, thereby causing the first photovoltaic panel 4 to rotate downward. The first photovoltaic panel 4 further drives the second photovoltaic panel 5 to rotate upward along the second connecting shaft 8 through the L-shaped rod 9 and the first connecting rod 7. At the same time as the first photovoltaic panel 4 rotates downward, the first gear 11 and the second gear 12 further drive the second photovoltaic panel 5 to rotate upward along the third connecting shaft 10. The device rotates to fold the first photovoltaic panel 4 and the second photovoltaic panel 5, reducing space occupation and making it easy to carry. When unfolding the device, the first threaded rod 14 is rotated in the opposite direction, which in turn drives the first slider 15 to move downward, thereby driving the first photovoltaic panel 4 to rotate upward, making it easy to unfold the first photovoltaic panel 4 and the second photovoltaic panel 5. When adjusting the angle of the battery assembly, the second threaded rod 19 is rotated, which drives the second slider 20 to move up and down, which in turn drives the second rack 21 to move up and down. The second rack 21 further drives the fourth gear 18 to rotate, which in turn drives the rotating plate 3 to rotate, thereby adjusting the angle of the battery assembly. It is highly practical.
