Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-9 One embodiment of the present invention is a portable expandable solar power generation device.

[0022] It includes a motherboard 1, a round rod 101 fixedly mounted on the side of the motherboard 1, a rotating shaft 102 fixedly mounted on the inner wall of the motherboard 1, and also includes an expansion device, an outer leg support device and an inner leg support device. The expansion device includes a fixing plate 2, which is rotatably mounted on the circumferential surface of a round rod 101. A rotating shaft 201 is rotatably mounted on the side of the fixing plate 2. A fixing plate 202 is rotatably mounted on the circumferential surface of the rotating shaft 201. A round rod 203 is rotatably mounted on the end of the fixing plate 202 away from the rotating shaft 201. A rotating shaft 304 is rotatably mounted through the side of the fixing plate 2. A photovoltaic panel 205 is fixedly mounted on the side of the rotating shaft 304. A rotating shaft 406 is fixedly mounted on the side of the photovoltaic panel 205. A roller 207 is rotatably mounted on the end of the rotating shaft 406 away from the photovoltaic panel 205. A fixing component 208 is fixedly mounted on the side of the photovoltaic panel 205. A short rod 209 is rotatably mounted on the circumferential surface of the fixing component 208. A photovoltaic panel 210 is fixedly mounted on the side of the short rod 209. A rotating shaft 511 is fixedly mounted on the photovoltaic panel 210. A rotating shaft 511 is rotatably mounted on the end of the rotating shaft 511 away from the photovoltaic panel 210. A roller 212 is rotatably mounted on the circumference of a rotating shaft 102. Another long plate 214 is rotatably mounted on the circumference of a rotating shaft 102. A block 215 is fixedly mounted on the long plate 213. Short nails 216 slide through the surface of the block 215. A fixing block 217 is fixedly mounted on the side of the long plate 214. When the long plates 213 and 214 are opened to be on the same plane as the main board 1, the track of the main board 1 is aligned with the long plate 212. 3. Track misalignment: To prevent jamming during opening, the second long plate 214 also pulls the right side of the second photovoltaic panel 210 from the right side, causing the second photovoltaic panel 210 to move to the right. When opening, pulling the second photovoltaic panel 210 drives the rotation shaft 5 211, roller 212, short rod 209, fixing part 208, first photovoltaic panel 205, fourth rotation shaft 206, first roller 207, etc., to rotate the first photovoltaic panel 205 and the second photovoltaic panel 210 from vertical to horizontal.

[0023] Main board 1, long plate 1 213 and long plate 2 214 are all equipped with tracks on their sides, and the tracks between main board 1 and long plate 1 213 and long plate 2 214 are misaligned. Long plate 1 213 is slightly longer than long plate 2 214. Rotating shaft 5 211 drives roller 2 212 to slide in the track. Photovoltaic panel 2 210 drives short rod 209 to move to the right. Short rod 209 drives fixing part 208 to move to the right. Fixing part 208 drives photovoltaic panel 1 205 to move to the right, which drives fixing plate 1 2, rotating shaft 201, fixing plate 2 202, round rod 203 and other components to move. Long plate 1 213 and long plate 2 214 open to the same plane as main board 1 and the track misalignment prevents jamming. When storing, lift round rod 203 to return the components to their original path. Long plate 2 214 rotates 90 degrees clockwise.

[0024] Roller 1 207 and roller 212 are set inside the track. A spring 1 is set between short nail 216 and block 1 215. Photovoltaic panel 1 205 drives rotating shaft 4 206 to move to the right. Rotating shaft 4 206 drives roller 1 207 to move to the right. During the movement, photovoltaic panel 210 rotates around rotating shaft 5 211 as the center, driving short rod 209 to rotate clockwise. It is fixed by short nail 216 and fixing block 217. The overall linkage is strong, the operation is convenient, the opening and storage process is smooth, and the structural design is compact and reasonable.

[0025] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, In this embodiment, during operation: Long plate 1 213 and long plate 214 are opened to be on the same plane as the main board 1. The track of the main board 1 is misaligned with the track of long plate 1 213. To prevent jamming during opening, long plate 214 is similarly opened by pulling the right side of photovoltaic panel 210 from the right. Photovoltaic panel 210 moves to the right, causing rotating shaft 5 211 to move to the right. Rotating shaft 5 211 causes roller 212 to slide within the track. Photovoltaic panel 210 then drives short rod 20... 9 moves to the right, short rod 209 drives fixed part 208 to move to the right, fixed part 208 drives photovoltaic panel 205 to move to the right, photovoltaic panel 205 drives rotating shaft 206 to move to the right, rotating shaft 206 drives roller 207 to move to the right. During the movement, photovoltaic panel 210 rotates around rotating shaft 211, driving short rod 209 to rotate clockwise, short rod 209 drives fixed part 208 to rotate counterclockwise, fixed part 208 drives photovoltaic panel 205 to rotate clockwise, and roller 207 to move counterclockwise. Rotating shaft 4 206 rotates counterclockwise around its center. The two photovoltaic panels 1 205 and 2 210 gradually change from their original vertical orientation to a horizontal orientation. Photovoltaic panel 1 205 drives rotating shaft 3 204 to move to the right and rotate around rotating shaft 4 206. Rotating shaft 3 204 drives fixed plate 1 2 to rotate counterclockwise around rod 1 101. Fixed plate 1 2 drives rotating shaft 2 201 to rotate counterclockwise. Rotating shaft 2 201 drives fixed plate 2 202 to rotate around rotating shaft 2 201. As the center rotates, the fixed plate 202 drives the round rod 203 downwards, opening the device. To retract the device, simply pull the round rod 203 upwards, and the photovoltaic panel 1 205 and photovoltaic panel 210 will return to their original positions. First, rotate the axis of the long plate 214 clockwise by 90 degrees, then rotate the long plate 1 213 counterclockwise by 90 degrees. The length of the long plate 1 213 is slightly greater than that of the long plate 214. Then, pull the short nail 216 upwards and push it into the round hole of the fixed block 217 to complete the retraction.

[0026] The outer leg support device includes an L-shaped rod 3, which is slidably mounted on the side of the track of the long plate 214. A square plate 301 is fixedly mounted on the side of the L-shaped rod 3, and an elastic plate 302 is fixedly mounted on the side of the L-shaped rod 3. A square plate 303 is fixedly mounted on the top of the square plate 215. A gear 304 is rotatably mounted on the side of the long plate 214, and a T-shaped rod 305 is fixedly mounted on the circumference of the gear 304. A square plate 306 is fixedly mounted on the side of the long plate 214, and a square rod 307 is installed through the surface of the square plate 306. A square plate 308 is fixedly mounted on the side of the square rod 307. A square plate 309 is fixedly installed on the side of the long plate 214. When the rotating shaft 5 211 moves to the right, it will abut against the square plate 301, pushing the square plate 301 to move to the right. The square plate 301 pushes the L-shaped rod 3 to move to the right. When the L-shaped rod 3 moves to the right, it drives the meshing gear 304 to rotate counterclockwise. The rotating shaft 5 211 moves to the right and abuts against the square plate 301, pushing the L-shaped rod 3 to move to the right, driving the gear 304 to rotate counterclockwise and the T-shaped rod 305 to rotate. At the same time, the L-shaped rod 3 pushes the elastic plate 302 to move to the right, and its inclined surface contacts the square plate 308, causing the spring 2 to deform.

[0027] The side of the elastic plate 302 closest to the square piece 308 is set as an inclined surface. A spring 2 is set between the L-shaped rod 3 and the square piece 303. A toothed block 1 is set below the L-shaped rod 3, and the toothed block 1 meshes with the gear 304. A spring 3 is set between the square rod 307 and the square piece 309. The gear 304 drives the T-shaped rod 305 to rotate counterclockwise around the gear 304. When the T-shaped rod 305 rotates 90 degrees counterclockwise, the L-shaped rod 3 drives the elastic plate 302 to move to the right. During the movement of the elastic plate 302 to the right, its inclined surface will contact the square piece 308. The spring 2 is deformed by the pressure of the L-shaped rod 3. The elastic plate 302 bends and makes a sound to indicate that it is stuck, which makes it easy to control and stop the pulling force. The outer leg support structure can cope with the change of center of gravity after the photovoltaic panel 205 and the photovoltaic panel 210 are unfolded.

[0028] The inner leg support device includes gear 2 4, a fixing rod 1 401 fixedly mounted on the circumference of gear 2 4, a fixing rod 2 402 fixedly mounted on the circumference of gear 2 4, a wheel 403 rotatably mounted on the side of fixing rod 2 402, a transmission rod 1 404 slidably mounted on the circumference of rotating shaft 4 206, a triangular block 1 405 fixedly mounted on the track, an L-shaped rod 2 406 slidably mounted on the track, an elastic plate 2 407 fixedly mounted on the side of L-shaped rod 2 406, a rectangular block 408 slidably mounted on the side of L-shaped rod 2 406, a triangular block 2 409 fixedly mounted below the rectangular block 408, and a baffle 410 fixedly mounted below the rectangular block 408. A stop block 411 is fixedly installed on the side of the rectangular block 408, and a square piece 412 is fixedly installed on the side of the square rod 307. When the rotating shaft 206 moves to the right, it will drive the transmission rod 404 to move to the right. The transmission rod 404 moves to the right and drives the meshing gear 4 to rotate clockwise. The gear 4 drives the fixed rod 401 and the fixed rod 402 to rotate clockwise. The rotating shaft 206 moves to the right and drives the transmission rod 404 and the gear 4 to rotate, so that the fixed rod 401 and the fixed rod 402 change direction and the roller 403 becomes the support of the fixed rod 401, preventing movement after unfolding. The rotating shaft 211 moves to the right and contacts the triangular block 409.

[0029] The transmission rod 404 has a sliding groove, and a toothed block 2 is provided below the transmission rod 404. The toothed block 2 meshes with the gear 4. The fixed rod 402 changes from the original vertical direction to the horizontal direction, and the fixed rod 401 changes from the horizontal direction to the vertical direction. The entire device changes from the original roller 403 used for movement to the fixed rod 401 used for support, which drives the rectangular block 408 to move upward. The rotating shaft 211 is located between the triangular block 409 and the baffle 410, pushing the baffle 410 to move the rectangular block 408, the L-shaped rod 406, and the elastic plate 407 to the right.

[0030] The rectangular block 408 has a sliding groove 2. The side of the elastic plate 2 407 near the square piece 5 412 is set as an inclined surface. This is to prevent the device from moving after unfolding. At the same time, when the rotating shaft 5 211 moves to the right, it will contact the triangular block 2 409. After being pushed by the rotating shaft 5 211, the triangular block 2 409 slides upward a short distance and then falls down. The upward movement of the triangular block 2 409 drives the rectangular block 408 to move upward. The sound of the elastic plate 2 407 and the square piece 5 412 locking together makes it easy to control. The triangular block 2 409 and the baffle 410 limit the device to prevent it from tilting. When storing, press the square rod 307 to disengage the square piece 5 412 from the elastic plate 2 407.

[0031] In this embodiment, during the movement of the rotating shaft 211 to the right, it will abut against the square piece 301, pushing the square piece 301 to the right. The square piece 301 pushes the L-shaped rod 3 to the right. During the movement of the L-shaped rod 3 to the right, it drives the meshing gear 304 to rotate counterclockwise. The gear 304 drives the T-shaped rod 305 to rotate counterclockwise around the gear 304. When the T-shaped rod 305 rotates 90 degrees counterclockwise, the L-shaped rod 3 drives the elastic plate 302 to move to the right. During the movement of the elastic plate 302 to the right, its inclined surface will contact the square piece 308. The spring 2 is subjected to the force of the L-shaped rod 3. The pressure deformation is such that a sound is heard after the elastic plate 302 bends, indicating that the elastic plate 302 and the square plate 308 are stuck. At this time, the pulling force on the photovoltaic panel 210 is stopped. Since the center of gravity of the entire device will change after the photovoltaic panels 205 and 210 are unfolded, the outer leg support structure is used to prevent damage to the long plates 213 and 214. When it is necessary to store it, press the square rod 307. The square rod 307 drives the square plate 308 to move downward. After the square plate 308 is separated from the elastic plate 302, the elastic plate 302 rebounds and resets under the action of the spring force.

[0032] In this embodiment, during operation: when the rotating shaft 206 moves to the right, it drives the transmission rod 404 to move to the right. The transmission rod 404 moves to the right, causing the meshing gear 4 to rotate clockwise. The gear 4 drives the fixed rods 401 and 402 to rotate clockwise. The fixed rod 402 gradually rotates from its original vertical direction. At this time, the fixed rod 401 rotates synchronously and contacts the ground. At this time, the wheel 403 and the fixed rod 401 simultaneously contact the ground and support the equipment, preventing the equipment from moving after unfolding. Meanwhile, during the movement of the rotating shaft 211 to the right, it contacts the triangular block 409. After being pushed by the rotating shaft 211, the triangular block 409 slides upward a short distance and then falls. The upward movement of the triangular block 409 drives the rectangular block 408 to move upward. At this time, the rotating shaft 211 will be between the triangular block 409 and the baffle 410. Subsequently, the rotating shaft 211 continues to move to the right, pushing the baffle 410. The baffle 410 moves the rectangular block 408 to the right, which in turn moves the L-shaped rod 406 to the right. The L-shaped rod 406 then moves the elastic plate 407 to the right. The elastic plate 407 moves to the right and contacts the square piece 412. A sound indicates that the elastic plate 407 and the square piece 412 are stuck, stopping the movement of the photovoltaic panel 210. The rotating shaft 211 is locked between the triangular block 409 and the baffle 410, acting as a limit and preventing the rotating shaft 211 from moving. After the moving shaft drives gear 4 to rotate, the device tilts. When storing, pressing the square rod 307 causes the square piece 412 to disengage from the elastic plate 407. When the rectangular block 408 resets, the stop block 411 contacts the triangular block 405 and drives the rectangular block 408 to move upward. At this time, the rotating shaft 211 continues to move to the left, and the rectangular block 408 stops moving, which will not affect storage. After being supported by the original fixed rod 401, it is now supported by the fixed rod 402 and the wheel 403, which facilitates movement.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
