[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention facilitates the unfolding and folding of the photovoltaic cell sheet by arranging the coordination of structures such as teeth and the first gear. The push rod inside the cylinder moves toward the direction close to the side cover, which drives the first photovoltaic panel to move through the slider, so that the end of the first photovoltaic panel away from the slider squeezes the inclined surface of the side cover, and the two side covers are rotated toward the two sides of the main shell by squeezing the inclined surface, so that the first photovoltaic panel is moved out from between the two side covers. When the first gear at the bottom of the first photovoltaic panel moves to the teeth in the second slide groove and meshes with it, the movement of the slider causes the first gear to rotate under the action of the teeth, so that the first photovoltaic panel drives the second photovoltaic panel to rotate and unfold on the bracket.

The elastic force and the air pressure in the sealing groove support the side cover, and indirectly support the first photovoltaic panel, so as to improve the stability of the first photovoltaic panel during its unfolding, and avoid the first photovoltaic panel from bending backward due to strong wind force on the side of the first photovoltaic panel close to the photovoltaic cell sheet. At the same time, a restoring force can be provided to the side cover during folding, so that autonomous unfolding and folding can be realized, and the device can be transported after being folded. When the device is not in operation or during transportation, the device can be folded, which can significantly reduce the floor space, facilitate transportation and storage, and also reduce maintenance costs. The device can also be folded in bad weather, thereby reducing maintenance costs and increasing the service life of the device. The present invention improves the stability of the unfolding of the first photovoltaic panel and the second photovoltaic panel by setting the cooperation of structures such as the support plate and the limit plate. During the unfolding of the first photovoltaic panel, the tooth groove at the top of the slider will mesh with the second gear, and the movement of the slider will drive the second gear to rotate. The rotation of the second gear will drive the support plate to rotate in the direction close to the first photovoltaic panel, and the second photovoltaic panel is applied with a force on the second photovoltaic panel through the rotation of the support plate to rotate the second photovoltaic panel around the first photovoltaic panel. When the first photovoltaic panel is fully unfolded, the support plate will squeeze the second photovoltaic panel to a vertical position, completing the unfolding of the photovoltaic panel mechanism, and the rotation of the second gear will drive the third gear to rotate in the opposite direction, so that the limit plate is rotated out of the groove and moves in the direction close to the top cover until it is against the top cover, supporting the second photovoltaic panel and the top cover, and cooperating with the support plate to fix the position of the second photovoltaic panel, thereby preventing the first photovoltaic panel from bending backward due to the strong wind force on the side of the second photovoltaic panel close to the photovoltaic cell, thereby protecting the structure.

The side of the top cover 109 away from the cylinder 105 is against the side of the second photovoltaic panel 307 away from the photovoltaic cell 305. The first photovoltaic panel 303 is provided with a third slide groove 202, and the fourth slide groove 306 and the tooth groove 308 are both located below the groove 107. The slider 301 is slidably connected to the first slide groove 102, the first gear 304 is slidably connected to the second slide groove 103, the first gear 304 is meshed with the tooth 104, and the end of the slider 301 away from the bracket 302 is slidably connected to the push rod 106.

[0026] The above scheme is adopted: when the side cover 201 is pushed to the two sides of the side cover 201 by the first photovoltaic panel 303, the side of the side cover 201 away from the first photovoltaic panel 303 is against the limit block 110, so that the piston rod 203 squeezes the spring 204 and the gas inside the sealing groove 108, and the side cover 201 is supported by the elastic force of the spring 204 and the air pressure in the sealing groove 108, and the first photovoltaic panel 303 is indirectly supported, so as to improve the stability of the first photovoltaic panel 303 during the unfolding process, and avoid the first photovoltaic panel 303 from bending backward due to the strong wind force on the side of the first photovoltaic panel 303 close to the photovoltaic cell 305, and at the same time, it can provide a restoring force to the side cover 201 when folding, so as to facilitate the transportation of the device after the device is folded.

[0027] like Figures 6 to 9 As shown, the support mechanism 4 includes two second gears 401 , and the sides of the two second gears 401 away from each other are fixedly connected to a support plate 402 , and the top of the second gear 401 is meshed with a third gear 403 , and the third gear 403 is fixedly connected to a limiting plate 404 .

[0028] The support plate 402 has an arc shape. The bottom of the second gear 401 passes through the inner wall of the main shell 101 and extends to the inside of the first slide groove 102. The third gear 403 and the second gear 401 are both rotatably connected to the inner wall of the main shell 101.

The two support plates 402 pass through the inner wall of the main shell 101 and extend to both sides of the main shell 101. The limit plate 404 is away from the third gear 403. One end of the gear 403 is abutted against the side of the top cover 109 away from the second photovoltaic panel 307, and the end of the support plate 402 away from the second gear 401 passes through the third slide groove 202 and extends to the side of the second photovoltaic panel 307 away from the top cover 109.

[0029] The above scheme is adopted: by setting the cooperation of structures such as the support plate 402 and the limit plate 404, the stability of the first photovoltaic panel 303 and the second photovoltaic panel 307 is improved. During the unfolding of the first photovoltaic panel 303, the tooth groove 308 at the top of the slider 301 will mesh with the second gear 401, and the movement of the slider 301 will drive the second gear 401 to rotate. The rotation of the second gear 401 will drive the support plate 402 to rotate in the direction close to the first photovoltaic panel 303. The rotation of the support plate 402 will successively pass through the two third slide grooves 202 on the side cover 201 and the first photovoltaic panel 303, and will abut against the side of the second photovoltaic panel 307 close to the photovoltaic cell 305. The rotation of the support plate 402 applies a force to the second photovoltaic panel 307, so that the second photovoltaic panel 307 rotates on the first photovoltaic panel 303. When 303 is fully unfolded, the support plate 402 will squeeze the second photovoltaic panel 307 to a vertical position, completing the unfolding of the photovoltaic panel mechanism 3. During this process, the side of the second photovoltaic panel 307 away from the photovoltaic cell 305 will squeeze the top cover 109, causing the top cover 109 to rotate on the top of the main shell 101, and the rotation of the second gear 401 will drive the third gear 403 to rotate in the opposite direction, so that the limit plate 404 is rotated out of the groove 107 and moves towards the top cover 109 until it is against the top cover 109, supporting the second photovoltaic panel 307 and the top cover 109, and cooperating with the support plate 402 to fix the position of the second photovoltaic panel 307, so as to prevent the first photovoltaic panel 303 from bending backwards due to the strong wind force on the side of the second photovoltaic panel 307 close to the photovoltaic cell 305, thereby protecting the structure.

[0030] The working principle and use process of the present invention are as follows: first, after the main shell 101 is installed, the photoelectric sensor on the main shell 101 senses sunlight. When sunlight is sensed, an electrical signal is sent to control the push rod 106 inside the cylinder 105 to move in the direction close to the side cover 201, and the first photovoltaic panel 303 is driven to move by the slider 301, so that the end of the first photovoltaic panel 303 away from the slider 301 squeezes the inclined surface of the side cover 201, and the two side covers 201 are rotated to the two sides of the main shell 101 by squeezing the inclined surface, so that the first photovoltaic panel 303 is moved out from between the two side covers 201. When the first gear 304 at the bottom of the first photovoltaic panel 303 moves to the teeth 104 in the second slide groove 103 and meshes with it, the movement of the slider 301 causes the first gear 304 to rotate under the action of the teeth 104, so that the first photovoltaic panel 303 drives the second photovoltaic panel 307 on the bracket 3 02 rotates and unfolds, and when the first gear 304 and the inner wall of the second slide groove 103 on the side away from the cylinder 105 are against each other, the two first photovoltaic panels 303 are fully unfolded, and at this time, the side cover 201 is pushed to the two sides of the side cover 201 by the first photovoltaic panel 303, so that the side of the side cover 201 away from the first photovoltaic panel 303 is against the limit block 110, so that the piston rod 203 squeezes the spring 204 and the gas inside the sealing groove 108, and the side cover 201 is supported by the elastic force of the spring 204 and the air pressure in the sealing groove 108, and the first photovoltaic panel 303 is indirectly supported, so as to improve the stability of the first photovoltaic panel 303 during the unfolding process, and avoid the first photovoltaic panel 303 from bending backward due to the strong wind force on the side of the first photovoltaic panel 303 close to the photovoltaic cell 305, and at the same time, it can provide a restoring force for the side cover 201 when folding; At the same time, during the unfolding of the first photovoltaic panel 303, the tooth groove 308 at the top of the slider 301 will mesh with the second gear 401, and the movement of the slider 301 will drive the second gear 401 to rotate, and the rotation of the second gear 401 will drive the support plate 402 to rotate in the direction close to the first photovoltaic panel 303, and the rotation of the support plate 402 will successively pass through the two third slide grooves 202 on the side cover 201 and the first photovoltaic panel 303, and abut against the side of the second photovoltaic panel 307 close to the photovoltaic cell 305, and a force is applied to the second photovoltaic panel 307 through the rotation of the support plate 402, so that the second photovoltaic panel 307 rotates on the first photovoltaic panel 303, and when the first photovoltaic panel 303 is fully unfolded, the support plate 402 will squeeze the second photovoltaic panel 307 to a vertical position, completing the unfolding of the photovoltaic panel mechanism 3, and in this process, the side of the second photovoltaic panel 307 away from the photovoltaic cell 305 will squeeze the top cover 109, so that the top cover 109 rotates on the top of the main shell 101; The rotation of the second gear 401 will drive the third gear 403 to rotate in the opposite direction, so that the limit plate 404 is rotated out of the groove 107 and moves towards the top cover 109 until it is against the top cover 109, supporting the second photovoltaic panel 307 and the top cover 109, and cooperating with the support plate 402 to fix the position of the second photovoltaic panel 307, so as to prevent the side of the second photovoltaic panel 307 close to the photovoltaic cell 305 from bending backward due to strong wind force, and the device can be folded in the non-working state or during transportation, which can significantly reduce the floor space occupied, facilitate transportation and storage, and also reduce maintenance costs.
