[0002] Solar energy comes from celestial bodies outside the Earth. It is the enormous energy released by the fusion of hydrogen nuclei in the sun at extremely high temperatures. Most of the energy needed by mankind comes directly or indirectly from the sun. With the increasing scarcity of resources, solar power generation devices are being used more and more in various aspects of people's lives.

[0003] A search revealed an existing patent (publication number: CN114567243A) disclosing a small portable solar power generation device, relating to the field of solar power generation devices. This small portable solar power generation device includes a power generation device housing, a movable storage mechanism, a top cover, and a battery body. Fixed solar panels are fixedly connected to the four sides of the power generation device housing, and movable solar panels are also fixedly installed around the four sides of the power generation device housing. The movable storage mechanism is located between the movable solar panels and the power generation device housing. This small portable solar power generation device utilizes the movable storage mechanism to control the opening or closing of the movable solar panels. When the movable solar panels are opened, the light-receiving area can be increased simultaneously by utilizing both the fixed and movable solar panels, enhancing the power generation speed of the solar power generation device. When the movable solar panels are closed, the overall footprint of the device is significantly reduced. During the development of this application, the inventors discovered the following problems with the existing technology: Most existing portable solar energy devices are laid at a fixed angle or require manual adjustment of orientation, making it impossible to face the sun directly in real time.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example 1 As attached Figures 1 to 8The portable tracking solar power generation device shown includes a protective housing 1. A lifting frame 2 is installed inside the protective housing 1. Screws 3 are connected to both sides of the bottom inner wall of the protective housing 1 via bearings. The screws 3 are threadedly connected to the edges of the lifting frame 2. Lifting motors 301 are embedded in the bottom inner walls of both sides of the protective housing 1. Two sets of lifting motors 301 are provided, and the output ends of the two sets of lifting motors 301 are fixedly connected to the corresponding screws 3 via couplings. A rotating platform 4 is installed on the top of the lifting frame 2, and a fixed connection is made to the center of the rotating platform 4. A battery box 5 is connected to a rotating platform 4. An auxiliary frame 6 is fixedly connected to one side surface of the rotating platform 4. A rotating rod 7 is connected to the top of the auxiliary frame 6 through a bearing. A support plate 8 is fixedly connected to the top outer wall of the rotating rod 7. A solar photovoltaic panel 9 is connected to the top of the support plate 8. An electric push rod 10 is provided on one side of the auxiliary frame 6. A slide groove 11 is provided on the bottom side of the support plate 8. A slider 12 is slidably connected inside the slide groove 11. The top of the electric push rod 10 and the slider 12 are hinged together. Side photovoltaic panels 14 are hinged to the four edges of the solar photovoltaic panel 9 through damping hinges 13.

[0021] The protective housing 1 serves a protective function, preventing the device from being bumped and affecting power generation during transport. When not in use, the entire power generation unit is housed within the protective housing 1. During operation, the lifting motor 301 is activated. A synchronous controller is installed between the two lifting motors 301, and the two lifting motors 301 are electrically connected to the synchronous controller. The two lifting motors 301 synchronously drive the two screws 3 to rotate synchronously, causing the lifting frame 2 to rise smoothly from the protective housing 1, increasing the overall height to avoid obstruction. The rotating platform 4 can rotate horizontally on the surface of the lifting frame 2. The extension and retraction of the electric push rod 10 is achieved by pushing the slider 12 to slide within the slide groove 11, forcing the support plate 8... Rotating around the rotating rod 7 allows for adjustment of the pitch angle of the solar photovoltaic panel 9. The four side photovoltaic panels 14 can be unfolded via the damping hinge 13 to increase the total light-receiving area. The damping hinge 13 has a limiting effect, allowing only right-angle rotation. The protective housing 1 provides comprehensive protection during transportation and when not in use. The horizontal rotation combined with the pitch adjustment ensures that the solar photovoltaic panel 9 can always maintain the optimal angle of sunlight, achieving tracking adjustment of the sun and significantly improving power generation efficiency. The side photovoltaic panels 14 are designed to fold to reduce volume when stored and unfold to greatly increase the power generation area when in operation, cleverly balancing portability and power output.

[0022] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details: In a preferred embodiment, a drive shaft 401 is fixedly connected to the center of the bottom end of the rotary table 4. The bottom end of the drive shaft 401 is connected to the lifting frame 2 via a bearing. A rotary motor 402 is provided on the outer wall of the bottom end of the lifting frame 2. The output end of the rotary motor 402 is connected to the drive shaft 401. An auxiliary ball bearing 403 is provided between the lifting frame 2 and the edge of the rotary table 4. When horizontal tracking is required, the rotary motor 402 is started, and the drive shaft 401 drives the entire rotary table 4 and all its components to rotate smoothly relative to the lifting frame 2, thereby realizing the horizontal rotation adjustment of the solar photovoltaic panel 9 and the side photovoltaic panel 14. The auxiliary ball bearing 403 provides support at the contact edge between the rotary table 4 and the lifting frame 2, changing sliding friction into rolling friction. The setting of the auxiliary ball bearing 403 greatly reduces the frictional resistance and energy loss during the rotation process, making the rotation easier, reducing the motor load, and improving the mechanical efficiency and long-term operational reliability of the entire system.

[0023] In a preferred embodiment, a battery pack 501 is installed inside the battery box 5. A charge / discharge controller 502 is installed on one side of the battery pack 501, and an inverter 503 is installed on one side of the charge / discharge controller 502. The electrical energy generated by the solar photovoltaic panel 9 and the side photovoltaic panel 14 can be transmitted to the charge / discharge controller 502 through wires. The charge / discharge controller 502 optimizes the management of electrical energy, charges the battery pack 501, and controls the discharge of electrical equipment. The inverter 503 converts the DC power output from the battery pack 501 into AC power to drive conventional household appliances. The battery pack 501 stores energy to ensure power supply at night or on cloudy days. The charge / discharge controller 502 maximizes the power generation efficiency of the solar panels and provides charge / discharge protection for the batteries, extending their lifespan.

[0024] In a preferred embodiment, a first bevel gear 15 is connected to the outer wall of the middle part of the rotating rod 7. A linkage rod 16 is connected to the top side of the battery box 5 via a bearing. A second bevel gear 17 is fixedly connected to the top of the linkage rod 16. The second bevel gear 17 meshes with the first bevel gear 15. A cam 18 is provided on the bottom side of the linkage rod 16. When the electric push rod 10 pushes the support plate 8 to adjust the pitch angle around the rotating rod 7, the rotating rod 7 rotates accordingly, and drives the first bevel gear 15 fixed on it to rotate. The first bevel gear 15 drives the second bevel gear 17 that meshes with it, thereby driving the linkage rod 16 to rotate, and finally causing the cam 18 fixed at the bottom of the linkage rod 16 to rotate.

[0025] In a preferred embodiment, air intake grilles 19 are provided on both outer walls of the battery box 5, and air intake holes 191 are provided on the outer wall of the battery box 5 adjacent to the air intake grilles 19. Air vanes 20 are provided on the outer walls of both sets of air intake grilles 19. The air vanes 20 are slidably connected to the outer wall of the battery box 5. Air grooves 21 are arranged on the surface of the air vanes 20, and the air grooves 21 match the air intake grilles 19. The air intake grilles 19 and the air intake holes 191 both serve to dissipate heat. The air vanes 20 can slide relative to the outer wall of the battery box 5, and the outer wall of the battery box 5 is provided with a track. The air vanes 20 can only slide linearly along the track. When the air vanes 20 slide, the air grooves 21 on their surface are relatively displaced from the air intake grilles 19 and the air intake holes 191 on the battery box 5, thereby changing the effective opening area of ​​the ventilation opening, so as to realize dynamic management of ventilation volume according to heat dissipation requirements.

[0026] In a preferred embodiment, the tops of the two sets of air deflectors 20 are connected by a movable strip 22, which is located on the top of the battery box 5. An arc-shaped plate 23 is fixedly connected to one outer wall of the movable strip 22, and the outer wall of the arc-shaped plate 23 abuts against the cam 18. A fixed stop block 24 is fixedly connected to one side of the top of the battery box 5. A spring 25 is provided on the outer wall of the fixed stop block 24 near the movable strip 22. Multiple springs 25 are arranged at equal intervals, and the end of the spring 25 away from the fixed stop block 24 is connected to the movable strip 22. During rotation, the cam 18 periodically pushes or releases the arc-shaped plate 23 it contacts. The movement of the arc-shaped plate 23 causes the movable strip 22 to move horizontally in a straight line, and the movable strip 22 simultaneously pulls the air deflectors 20 on both sides to slide together. By changing the opening of the air intake grille 19, the spring 25 always applies an elastic force to the moving strip 22, causing the air deflector 20 to tend to close. When the panel is close to horizontal at noon, the cam 18 rotates to the large radius part to push the arc plate 23, overcoming the elastic force of the spring 25, opening the air intake grille 19, increasing the air intake volume, and enhancing heat dissipation. When the panel is close to vertical in the morning or evening, the cam 18 turns to the small radius part, and the elastic force of the spring 25 pulls the moving strip 22 to reset, causing the air intake grille 19 to close or reduce its opening, thereby reducing internal heat loss, keeping the battery operating at a suitable temperature, ensuring that the opening of the air intake grille 19 matches the solar intensity, and using existing tracking motion drive without additional energy consumption. Moreover, the cam 18 has a single-sided protruding structure, and the radius of the cam 18 can be fully changed within a limited angle of 90 degrees.

[0027] In a preferred embodiment, the edge frame of the side photovoltaic panel 14 is provided with a toothed groove 26, and a cleaning box 27 is fixedly connected to each of the four edges of the protective housing 1. A cleaning rod 28 is connected to the inner wall of the middle part of the cleaning box 27 via a bearing. A linkage gear 29 is fixedly connected to the edge of the cleaning rod 28, and the linkage gear 29 matches the toothed groove 26. A brush rod 30 is movably connected to the inner wall of the cleaning box 27 via a bearing. Multiple sets of brush rods 30 are provided and arranged at equal intervals. A cleaning brush 31 is fixedly connected to the outer wall of the brush rod 30. The cleaning brush 31 is close to the side photovoltaic panel 14. When the lifting frame 2 rises or falls, the side photovoltaic panel 14 moves accordingly. When passing through the cleaning box 27, the toothed grooves 26 on the edge of the side photovoltaic panel 14 will mesh with the linkage gear 29 inside the cleaning box 27. The vertical movement of the side photovoltaic panel 14 drives the linkage gear 29 to rotate, thereby driving the cleaning rod 28 to rotate. At the same time, the side photovoltaic panel 14 comes into contact with the cleaning brush 31 during the movement, thereby performing a certain degree of cleaning. Before and after each use, the side photovoltaic panel 14 can be automatically cleaned during the lifting process, effectively scraping off the dust and debris on the surface, maintaining the high-efficiency power generation capacity of the side photovoltaic panel 14, realizing fully automatic maintenance-free cleaning. Only the solar photovoltaic panel 9 in the middle needs to be manually cleaned, reducing the burden of cleaning the power generation device.

[0028] In a preferred embodiment, a first helical gear 32 is fixedly connected to the outer wall of the cleaning rod 28. Multiple sets of first helical gears 32 are provided, and their positions match those of the brush rod 30. A second helical gear 33 is fixedly connected to the end of the brush rod 30. The second helical gear 33 meshes with the first helical gear 32. When the cleaning rod 28 is driven to rotate by the linkage gear 29, the multiple first helical gears 32 fixed on it rotate synchronously. Each first helical gear 32 drives the second helical gear 33 that meshes with it, thereby driving the corresponding brush rod 30 and its cleaning brush 31 to rotate, performing large-area and high-efficiency brushing on the surface of the side photovoltaic panel 14, significantly improving the cleaning effect.

[0029] In a preferred embodiment, a photoresistor array 34 is provided on the surface of the solar photovoltaic panel 9, a gyroscope 35 is provided on the bottom of the solar photovoltaic panel 9, a control unit 36 ​​is provided on one side of the inner wall of the battery box 5, and an auxiliary roller 37 is provided at the bottom edge of the protective shell 1. The photoresistor array 34 detects the light intensity in different directions in real time and transmits the signal to the control unit 36. The gyroscope 35 detects the current attitude angle of the solar photovoltaic panel 9. The control unit 36 ​​integrates the light and attitude information, calculates the optimal angle of the sun through an algorithm, and then issues a command to control the rotary motor 402 and the electric push rod 10 to achieve precise dual-axis tracking. The auxiliary roller 37 facilitates the movement of the entire device.

[0030] The working process of this application is as follows: First, during operation, the lifting motor 301 starts, driving the two screws 3 to rotate synchronously, causing the lifting frame 2 to rise smoothly from the protective housing 1, increasing the overall height to avoid obstruction. The rotating platform 4 can rotate horizontally on the surface of the lifting frame 2. The extension and retraction of the electric push rod 10 is achieved by pushing the slider 12 to slide within the slide groove 11, forcing the support plate 8 to rotate around the rotating rod 7, thereby adjusting the pitch angle of the solar photovoltaic panel 9. The four side photovoltaic panels 14 can be unfolded through the damping hinge 13 to increase the total light-receiving area. The photoresistor array 34 detects the light intensity in different directions in real time and transmits the signal to the control unit 36. The gyroscope 35 detects the current attitude angle of the solar photovoltaic panel 9. The control unit 36 ​​integrates the light and attitude information, calculates the optimal angle of the sun through an algorithm, and then issues commands to control the rotating motor 402 and the electric push rod 10 to achieve… Precise dual-axis tracking: When the electric push rod 10 pushes the support plate 8 to adjust the pitch angle around the rotating rod 7, the rotating rod 7 rotates accordingly, driving the first bevel gear 15 fixed on it to rotate. The first bevel gear 15 drives the second bevel gear 17 meshing with it, which in turn drives the linkage rod 16 to rotate, ultimately causing the cam 18 fixed at the bottom of the linkage rod 16 to rotate. When the panel is close to horizontal at noon, the cam 18 rotates to the large radius part to push the arc plate 23, overcoming the elastic force of the spring 25, opening the air intake grille 19, increasing the air intake volume, and enhancing heat dissipation. When the panel is close to vertical in the morning or evening, the cam 18 turns to the small radius part, and the elastic force of the spring 25 pulls the moving strip 22 to reset, causing the air intake grille 19 to close or reduce its opening, thereby reducing internal heat loss, keeping the battery operating at a suitable temperature, ensuring that the opening of the air intake grille 19 matches the solar intensity, and utilizing the existing tracking motion drive without additional energy consumption. When the lifting frame 2 rises or falls, the side photovoltaic panel 14 moves accordingly. When it passes the cleaning box 27, the toothed groove 26 on the edge of the side photovoltaic panel 14 meshes with the linkage gear 29 inside the cleaning box 27. The vertical movement of the side photovoltaic panel 14 drives the linkage gear 29 to rotate, thereby driving the cleaning rod 28 to rotate. At the same time, the side photovoltaic panel 14 comes into contact with the cleaning brush 31 during the movement, thereby cleaning to a certain extent. Before and after each use, the side photovoltaic panel 14 can be automatically cleaned during the lifting process, effectively scraping off the dust and debris on the surface, maintaining the high-efficiency power generation capacity of the side photovoltaic panel 14, and realizing fully automatic maintenance-free cleaning. Only the solar photovoltaic panel 9 in the middle needs to be manually cleaned, reducing the burden of cleaning the power generation device.
