[0002] With the transformation of the global energy structure and the deepening of the concept of sustainable development, the application of clean energy is becoming increasingly widespread. As a clean energy source that is inexhaustible and renewable, the development and utilization of solar energy have attracted much attention.

[0003] Traditional photovoltaic power generation systems have limitations such as large volume and difficulty in moving after being installed and fixed, and it is difficult to meet the electricity demand in scenarios such as outdoor activities, emergency rescue, and power supply in remote areas. Summary of the Invention

[0004] The purpose of the present invention is to provide a mobile and portable photovoltaic power generation device with a simple structure and reasonable design to solve the above problems.

[0005] The present invention achieves the above purpose through the following technical solutions:

[0006] A mobile and portable photovoltaic power generation device includes two parallel rectangular sliding tubes. Both ends of the rectangular sliding tubes are slidably connected with sliding rods. Above the rectangular sliding tubes, there are multiple photovoltaic panels with backplates installed on their lower surfaces. Adjacent two of the backplates are rotatably connected through hinges. At the end of the backplate, two connecting rods are arranged in a staggered manner. The middle section of the connecting rod is rotatably connected with the end of the backplate. The corresponding ends of the connecting rods arranged on adjacent two backplates are rotatably connected through a rotating shaft, so that the connecting rods between adjacent backplates enclose a rhombus-shaped frame structure. At the lower surface of the backplates on the left and right sides, support rods are rotatably connected. The bottom end of the support rod is slidably sleeved with a support sleeve. One end of the support sleeve away from the support rod is fixed to the end of the sliding rod outside the rectangular sliding tube. On the upper surfaces of the two rectangular sliding tubes, protective frames are installed. On the protective frames, a driving device for driving the sliding rod to slide along the length direction of the rectangular sliding tube is horizontally installed. A support plate is fixedly connected between the two rectangular sliding tubes. On the upper surface of the support plate, a power storage device electrically connected to the photovoltaic panel is arranged.

[0007] As a further optimized solution of the present invention, a mounting plate is fixedly connected between the two sliding rods at the same end of the rectangular sliding tube. A driving wheel is rotatably connected to the bottom of one of the mounting plates. A driving motor for driving the driving wheel to rotate is installed on the mounting plate above the driving wheel.

[0008] As a further optimized solution of the present invention, universal wheels are rotatably connected to both ends of the bottom of the other mounting plate. The bottom height of the universal wheels is flush with the bottom height of the driving wheel.

[0009] As a further optimized solution of the present invention, ear plates are fixedly connected to the sides of the bottoms of the two back plates on the left and right sides that are away from each other. The top end of the support rod is arranged in a dislocation manner with the ear plate, and the top end of the support rod is rotatably connected to the ear plate through a connecting shaft.

[0010] As a further optimized solution of the present invention, the driving device is an electric telescopic rod fixedly installed on the protective frame. The output end of the electric telescopic rod is fixed to the support sleeve, and the telescopic length of the electric telescopic rod is less than the length of the section where the sliding rod is accommodated in the rectangular sliding tube when the electric telescopic rod is in a contracted state.

[0011] As a further optimized solution of the present invention, the power storage device includes a power supply box fixedly installed on the upper surface of the support plate. A storage battery is installed in the power supply box, and a micro-inverter electrically connected to the storage battery is installed on one of the power supply boxes.

[0012] As a further optimized solution of the present invention, the top heights of the power supply box and the protective frame are lower than the bottom height of the back plate when the photovoltaic panel is in a folded state.

[0013] As a further optimized solution of the present invention, a push handle in a U-shaped structure is arranged between the two support sleeves at one end of the rectangular sliding tube. The two ends of the push handle are respectively fixed to the middle sections of the two support sleeves, and anti-slip lines are provided on the middle section of the push handle.

[0014] The beneficial effects of the present invention are as follows: The setting of the driving motor and the driving wheel can assist the user in moving the overall device, making it more labor-saving for the user to move. The electric telescopic rod pushes the sliding rod to slide along the length direction of the rectangular sliding tube through telescoping, and cooperates with the support rod to slide along the height direction of the support sleeve, which can drive the connecting rod between adjacent back plates to enclose and form a rhombus frame-like structure deformation, so as to drive the back plate to rotate around the hinge connection position, and unfold or fold the photovoltaic panel installed on the back plate, and as much as possible avoid the limitations of the traditional photovoltaic power generation system such as large volume and difficulty in moving after installation and fixation.

Specific embodiments

[0021] The present application will be further described in detail below with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Embodiment

[0023] As Figure 1 - Figure 5 shown, a mobile portable photovoltaic power generation device includes two parallel rectangular sliding tubes 1. Both ends of the rectangular sliding tube 1 are slidably connected with sliding rods 2. The length of the rectangular sliding tube 1 is greater than the total length of the two sliding rods 2 installed at both ends of the rectangular sliding tube 1, so that the two sliding rods 2 at both ends of the rectangular sliding tube 1 can be slid to be completely accommodated in the rectangular sliding tube 1;

[0024] A mounting plate 3 is fixedly connected between the two sliding rods 2 at the same end of the rectangular sliding tube 1. A driving wheel 4 is rotatably connected to the bottom of one of the mounting plates 3, and a driving motor 6 for driving the driving wheel 4 to rotate is installed on the mounting plate 3 above the driving wheel 4. When the driving motor 6 is started, the driving motor 6 can drive the driving wheel 4 to rotate and roll along the ground, thereby driving the whole device to move, making it more labor-saving and convenient for users to move the whole photovoltaic power generation device;

[0025] Both ends of the bottom of the other mounting plate 3 are rotatably connected with universal wheels 5. The bottom height of the universal wheels 5 is flush with the bottom height of the driving wheel 4. The universal wheels 5 are provided to change the moving direction of the whole photovoltaic power generation device through the rotation of the universal wheels 5. At the same time, through the cooperation of the universal wheels 5 and the driving wheel 4 to support from both ends, the sliding rods 2 and the rectangular sliding tube 1 are supported to be separated from the ground. When the length of the section of the sliding rod 2 outside the rectangular sliding tube 1 is adjusted by sliding the sliding rod 2, the friction between the sliding rod 2 and the ground can be reduced through the universal wheels 5 and the driving wheel 4, facilitating the adjustment of the length of the section of the sliding rod 2 outside the rectangular sliding tube 1;

[0026] Above the rectangular sliding tube 1, there are multiple photovoltaic panels 8 with backplates 7 mounted on their lower surfaces. Adjacent two backplates 7 are rotatably connected by hinges 9. At the end of the backplate 7, two connecting rods 10 are arranged in a staggered manner. The middle section of the connecting rod 10 is rotatably connected to the end of the backplate 7. The corresponding ends of the connecting rods 10 arranged on adjacent two backplates 7 are rotatably connected by a rotating shaft 11, so that the connecting rods 10 between adjacent backplates 7 enclose a rhombus-shaped frame structure. When the left and right sides of the rhombus-shaped frame structure are pressed, due to the corresponding ends of the connecting rods 10 arranged on adjacent two backplates 7 being rotatably connected by a rotating shaft 11, the rhombus-shaped frame structure can drive the backplate 7 to rotate around the hinge 9 through deformation, folding multiple photovoltaic panels 8. When the left and right sides of the rhombus-shaped frame structure are subjected to tensile force, the rhombus-shaped frame structure can deform in the reverse direction, driving the backplate 7 to rotate around the hinge 9 and unfolding multiple photovoltaic panels 8;

[0027] On the far sides of the bottoms of the two backplates 7 located on the left and right sides, ear plates 12 are fixedly connected. On one side of the ear plate 12, a support rod 13 is arranged in a staggered manner. The top end of the support rod 13 is rotatably connected to the ear plate 12 through a connecting shaft. The bottom end of the support rod 13 is slidably sleeved with a support sleeve 14. The end of the support sleeve 14 away from the support rod 13 is fixed to the end of the sliding rod 2 outside the rectangular sliding tube 1. When the photovoltaic panel 8 is folded or unfolded, the support rod 13 can slide along the height direction of the support sleeve 14, and cooperate with the sliding rod 2 to slide along the length direction of the rectangular sliding tube 1 to adapt to the rotation path of the backplate 7, and try to avoid forming movement interference during the folding or unfolding of the photovoltaic panel 8;

[0028] On the upper surfaces of the two rectangular sliding tubes 1, protective frames 15 are installed. On the protective frame 15, a driving device for driving the sliding rod 2 to slide along the length direction of the rectangular sliding tube 1 is horizontally installed. The driving device is an electric telescopic rod 16 fixedly installed on the protective frame 15. The output end of the electric telescopic rod 16 is fixed to the support sleeve 14, and the telescopic length of the electric telescopic rod 16 is less than the length of the section of the sliding rod 2 accommodated in the rectangular sliding tube 1 when the electric telescopic rod 16 is in a contracted state. When it is necessary to unfold or fold the photovoltaic panel 8, the electric telescopic rod 16 can be started. During the telescopic process of the electric telescopic rod 16, it can push the support sleeve 14 to drive the sliding rod 2 to slide along the length direction of the rectangular sliding tube 1, and cooperate with the support rod 13 to slide up and down along the height direction of the support sleeve 14, realizing the electric control of the unfolding and folding of the photovoltaic panel 8, making it more convenient and labor-saving for users to use;

[0029] A support plate 17 is fixedly connected between the two rectangular slide tubes 1. A power storage device electrically connected to the photovoltaic panel 8 is arranged on the upper surface of the support plate 17. The power storage device includes a power box 18 fixedly installed on the upper surface of the support plate 17. A battery 19 is installed in the power box 18. One of the power boxes 18 is equipped with a micro inverter 20 electrically connected to the battery 19. The power box 18 is provided to cooperate with the protective frames 15 on both sides to protect the battery 19, so as to avoid the battery 19 from being damaged by external impact when the overall photovoltaic power generation device is transferred. The micro inverter 20 is provided to convert the DC power stored in the battery 19 into AC power, so as to facilitate the power supply to external electrical equipment through the battery 19;

[0030] The top height of the power box 18 and the protective frame 15 is lower than the bottom height of the back plate 7 when the photovoltaic panel 8 is in the folded state, which can avoid the problem that the back plate 7 rotates and collides with the upper surface of the power box 18 during the folding process of the photovoltaic panel 8, which may easily cause damage to the photovoltaic panel 8 and the battery 19;

[0031] A U-shaped push handle 21 is provided between the two supporting sleeves 14 at one end of the rectangular sliding tube 1. The two ends of the push handle 21 are respectively fixed to the middle sections of the two supporting sleeves 14. The middle section of the push handle 21 is provided with anti-slip grooves. When the entire photovoltaic power generation device needs to be moved, the user can push and pull the entire device through the push handle 21, cooperate with the drive motor 6 to drive the drive wheel 4 to rotate and the universal wheel 5 to steer, so as to facilitate moving the entire photovoltaic power generation device to a suitable position.

[0032] It should be noted that for this mobile portable photovoltaic power generation device, during use, the entire device is pushed and pulled through the push handle 21. In cooperation with the driving motor 6 driving the driving wheel 4 to rotate and the steering of the universal wheel 5, after moving the entire photovoltaic power generation device to a suitable position, the electric telescopic rod 16 can be activated to extend. During the extension of the electric telescopic rod 16, the sliding rods 2 at both ends of the rectangular sliding tube 1 are pushed to slide outwards through the support sleeve 14, pulling the adjacent back plates 7 to form a rhombic frame structure surrounded by the connecting rods 10. Since the corresponding ends of the connecting rods 10 provided on the adjacent two back plates 7 are rotatably connected through the rotating shafts 11, when the left and right sides of the rhombic frame structure are subjected to tensile forces, the rhombic frame structure can drive the back plates 7 to rotate around the hinges 9 through deformation, and unfold multiple photovoltaic panels 8. At this time, the photovoltaic panels 8 can receive light to generate electric energy, and the electric energy is stored in the storage battery 19. When it is necessary to move the position of the entire photovoltaic power generation device, the electric telescopic rod 16 can be activated to contract. During the contraction of the electric telescopic rod 16, the sliding rods 2 at both ends of the rectangular sliding tube 1 are driven to slide into the rectangular sliding tube 1, thereby squeezing the rhombic frame structure formed by the adjacent back plates 7 surrounded by the connecting rods 10 to deform in the reverse direction. At the same time, in cooperation with the sliding of the support rod 13 along the height direction of the support sleeve 14, multiple photovoltaic panels 8 are folded to reduce the floor area of the entire photovoltaic power generation device. Then, the push handle 21 is used to push and pull the entire device, and in cooperation with the driving motor 6 driving the driving wheel 4 to rotate and the steering of the universal wheel 5, the entire photovoltaic power generation device can be moved again, which is convenient for users to use.

[0033] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
