[0001] The present invention belongs to the technical field of photovoltaic panels, and specifically relates to a bracket for a distributed photovoltaic panel that can be autonomously deployed and folded. Background Art

[0002] With the development and progress of society, the sustainable development of the environment and resources has received increasing attention, and the utilization of new energy has become increasingly important. The process of solar photovoltaic power generation is simple, without mechanical rotating parts, does not consume fuel, does not emit any substances including greenhouse gases, is noise-free and pollution-free, and solar energy resources are widely distributed and inexhaustible. Therefore, compared with new power generation technologies such as wind power generation, biomass power generation, and nuclear power generation, photovoltaic power generation is a renewable energy power generation technology with the most ideal characteristics of sustainable development.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] Through the cooperation of structures such as the teeth and the first gear, the present invention facilitates the unfolding and folding of the photovoltaic cells. When the push rod inside the cylinder moves towards the side cover, it drives the first photovoltaic panel to move through the slider, causing the end of the first photovoltaic panel away from the slider to squeeze the inclined surface of the side cover. By squeezing the inclined surface, the two side covers rotate towards both sides of the main body housing, enabling the first photovoltaic panel to move 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 chute and meshes with them, the movement of the slider causes the first gear to rotate under the action of the teeth, driving the first photovoltaic panel to drive the second photovoltaic panel to rotate and unfold on the bracket. At this time, the piston rod squeezes the gas inside the spring and the sealing groove. The elastic force of the spring and the air pressure inside the sealing groove support the side cover, indirectly supporting the first photovoltaic panel, improving the stability of the unfolding of the first photovoltaic panel during the unfolding process of the first photovoltaic panel, and preventing the situation where the side of the first photovoltaic panel close to the photovoltaic cells is bent backward due to strong wind. At the same time, it can provide a restoring force for the side cover during folding, enabling autonomous unfolding and folding, facilitating the transportation of the device after folding. In the non-working state or during transportation, folding the device can significantly reduce the floor area, facilitate transportation and storage, and also reduce the maintenance cost. Moreover, the device can be folded in bad weather, thereby reducing the maintenance cost and increasing the service life of the device;

[0018] Through the cooperation of structures such as the support plate and the limit plate, the present invention improves the stability of the deployment of the first photovoltaic panel and the second photovoltaic panel. During the deployment of the first photovoltaic panel, the tooth groove at the top of the slider will engage with the second gear. The rotation of the second gear is driven by the movement of the slider, and the rotation of the second gear will drive the support plate to rotate towards the first photovoltaic panel. By the rotation of the support plate, a force is exerted on the second photovoltaic panel, causing the second photovoltaic panel to rotate when the first photovoltaic panel rotates. When the first photovoltaic panel is fully deployed, the support plate will squeeze the second photovoltaic panel to a vertical position, completing the deployment of the photovoltaic panel mechanism. The rotation of the second gear will drive the third gear to rotate in the opposite direction, causing the limit plate to rotate out of the groove and move towards the top cover until it abuts 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, avoiding the situation where the side of the second photovoltaic panel close to the photovoltaic cell is bent backward due to strong wind, and protecting the structure.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1 to 9 shown, the present invention provides a bracket for a distributed photovoltaic panel that can be autonomously unfolded and folded, including a main body mechanism 1, a buffer mechanism 2 is arranged on the main body mechanism 1, a photovoltaic panel mechanism 3 is arranged inside the main body mechanism 1, a support mechanism 4 is arranged inside the main body mechanism 1, and the support mechanism 4 is located above the photovoltaic panel mechanism 3;

[0031] The main body mechanism 1 includes a main body housing 101, a first chute 102 is opened inside the main body housing 101, a second chute 103 is opened at the bottom of the inner wall of the first chute 102, several teeth 104 are fixedly connected to both sides of the inner wall of the second chute 103, a cylinder 105 is fixedly connected to the rear of the main body housing 101, a push rod 106 is slidably connected to the side of the cylinder 105 close to the main body housing 101, two grooves 107 are opened at the top of the main body housing 101, two sealing grooves 108 are opened inside the main body housing 101, a top cover 109 is rotatably connected to the top of the main body housing 101, and limit blocks 110 are fixedly connected to both sides of the main body housing 101.

[0032] The two sealing grooves 108 are respectively located between the two limiting blocks 110. The top cover 109 is located on the side of the groove 107 away from the cylinder 105. The top cover 109 is located above the tooth teeth 104. The groove 107 is located above the second chute 103. The push rod 106 penetrates through the surface of the main body housing 101 and extends into the first chute 102. The sealing groove 108 is located below the second chute 103.

[0033] The buffer mechanism 2 includes two side covers 201. Third chutes 202 are provided on both of the two side covers 201. A piston rod 203 is fixedly connected to the side cover 201. A spring 204 is fixedly connected to the side of the piston rod 203 away from the side cover 201. The outer shape of the side cover 201 is in an "L" shape. The outer shape of the piston rod 203 is in an arc shape. The third chute 202 is located above the piston rod 203. An inclined surface is provided inside the side cover 201.

[0034] The photovoltaic panel mechanism 3 includes a slider 301. A bracket 302 is fixedly connected to the slider 301. Two first photovoltaic panels 303 are rotatably connected to the side of the bracket 302 away from the slider 301. A first gear 304 is fixedly connected to the bottom of the first photovoltaic panel 303. A photovoltaic cell 305 is fixedly connected to the side of the first photovoltaic panel 303 away from the bracket 302. A fourth chute 306 is provided on the top of the first photovoltaic panel 303. A second photovoltaic panel 307 is rotatably connected to the top of the first photovoltaic panel 303. A plurality of tooth grooves 308 are evenly provided on the top of the slider 301.

[0035] Adopting the above solution: By setting up the cooperation of structures such as the teeth 104 and the first gear 304, it is convenient to unfold and fold the photovoltaic cell 305. The photoelectric inductor on the main body housing 101 senses sunlight. When sunlight is sensed, an electrical signal is sent to control the movement of the push rod 106 inside the cylinder 105 in the direction approaching the side cover 201. The first photovoltaic panel 303 is driven by the slider 301 to move, and the end of the first photovoltaic panel 303 away from the slider 301 presses against the inclined surface of the side cover 201. By pressing the inclined surface, the two side covers 201 rotate towards both sides of the main body housing 101, and 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 chute 103 and meshes with them, the movement of the slider 301 causes the first gear 304 to rotate under the action of the teeth 104, driving the second photovoltaic panel 307 to rotate and unfold on the bracket 302. When the first gear 304 abuts against the inner wall of the second chute 103 on the side away from the cylinder 105, the two first photovoltaic panels 303 are fully unfolded, enabling autonomous unfolding. In the non-working state or during transportation, the device can be folded, which can significantly reduce the floor area, facilitate transportation and storage, and at the same time reduce the maintenance cost. Also, in bad weather, the device can be folded, thereby reducing the maintenance cost and increasing the service life of the device.

[0036] As Figures 3 to 7 shown, one end of the side cover 201 away from the inclined surface is rotatably connected to the main body housing 101. The side cover 201 is located below the top cover 109. The piston rod 203 passes through the limit block 110 and the side of the main body housing 101 and extends into the sealing groove 108. The piston rod 203 is slidably connected to the sealing groove 108. The piston rod 203 is elastically connected to the inner wall of the sealing groove 108 through the spring 204.

[0037] One side of the second photovoltaic panel 307 away from the bracket 302 is fixedly connected with a photovoltaic cell 305. The two second photovoltaic panels 307 are located between the two first photovoltaic panels 303. One side of the top cover 109 away from the cylinder 105 abuts against one side of the second photovoltaic panel 307 away from the photovoltaic cell 305. A third chute 202 is provided on the first photovoltaic panel 303. The fourth chute 306 and the tooth groove 308 are both located below the groove 107. The slider 301 is slidably connected to the first chute 102. The first gear 304 is slidably connected to the second chute 103. The first gear 304 meshes with the teeth 104. One end of the slider 301 away from the bracket 302 is slidably connected to the push rod 106.

[0038] Adopting the above solution: When the side cover 201 is pushed to both 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 abuts against the limit block 110, so that the piston rod 203 squeezes the gas inside the spring 204 and the sealing groove 108. The side cover 201 is supported by the elastic force of the spring 204 and the air pressure in the sealing groove 108, indirectly supporting the first photovoltaic panel 303, improving the stability of the unfolding of the first photovoltaic panel 303 during the unfolding process of the first photovoltaic panel 303, and avoiding the situation that the side of the first photovoltaic panel 303 close to the photovoltaic cell 305 is bent backward due to strong wind. At the same time, a restoring force can be provided for the side cover 201 during folding, facilitating the transportation of the device after folding the device.

[0039] As Figures 6 to 9 shown, the support mechanism 4 includes two second gears 401. One side of each of the two second gears 401 away from each other is fixedly connected with a support plate 402. A third gear 403 is meshed with the top of the second gear 401, and a limit plate 404 is fixedly connected to the third gear 403.

[0040] The outer shape of the support plate 402 is arc-shaped. The bottom of the second gear 401 penetrates through the inner wall of the main body housing 101 and extends into the first chute 102. Both the third gear 403 and the second gear 401 are rotatably connected to the inner wall of the main body housing 101. The third gear 403 penetrates through the inner wall of the main body housing 101 and extends into the groove 107. Both of the two support plates 402 penetrate through the inner wall of the main body housing 101 and extend to both sides of the main body housing 101. One end of the limit plate 404 away from the third gear 403 abuts against the side of the top cover 109 away from the second photovoltaic panel 307. One end of the support plate 402 away from the second gear 401 penetrates through the third chute 202 and extends to the side of the second photovoltaic panel 307 away from the top cover 109. One end of the support plate 402 away from the second gear 401 abuts against the end of the second photovoltaic panel 307 away from the top cover 109. The bottom of the second gear 401 is meshed with the tooth groove 308, and a part of the second gear 401 is slidably connected with the fourth chute 306.

[0041] Adopting the above solution: By setting up the cooperation of structures such as the support plate 402 and the limit plate 404, the stability of the deployment of the first photovoltaic panel 303 and the second photovoltaic panel 307 is improved. During the deployment of the first photovoltaic panel 303, the tooth groove 308 at the top of the slider 301 will engage with the second gear 401. The rotation of the second gear 401 is driven by the movement of the slider 301. The rotation of the second gear 401 will drive the support plate 402 to rotate towards the first photovoltaic panel 303. The support plate 402 will successively pass through the two third chutes 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. By the rotation of the support plate 402, a force is exerted on the second photovoltaic panel 307, causing the second photovoltaic panel 307 to rotate when the first photovoltaic panel 303 rotates. When the first photovoltaic panel 303 is fully deployed, the support plate 402 will squeeze the second photovoltaic panel 307 into a vertical position, completing the deployment 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 body housing 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 rotates out of the groove 107 and moves towards the top cover 109 until it abuts 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, preventing the situation that the side of the second photovoltaic panel 307 close to the photovoltaic cell 305 causes the first photovoltaic panel 303 to bend backward due to strong wind, and protecting the structure.

[0042] Working principle and usage process of the present invention: First, after installing the main body housing 101, the photoelectric inductor on the main body housing 101 senses sunlight. When sunlight is sensed, an electrical signal is sent to control the push rod 106 inside the cylinder 105 to move towards the side cover 201. The slider 301 drives the first photovoltaic panel 303 to move, causing the end of the first photovoltaic panel 303 away from the slider 301 to press against the inclined surface of the side cover 201. By pressing the inclined surface, the two side covers 201 rotate towards both sides of the main body housing 101, so that the first photovoltaic panel 303 moves out from between the two side covers 201. When the first gear 304 at the bottom of the first photovoltaic panel 303 moves to and meshes with the tooth 104 in the second chute 103, the movement of the slider 301 causes the first gear 304 to rotate under the action of the tooth 104, making the first photovoltaic panel 303 drive the second photovoltaic panel 307 to rotate and unfold on the bracket 302. When the first gear 304 abuts against the inner wall of the second chute 103 on the side away from the cylinder 105, the two first photovoltaic panels 303 are fully unfolded. At this time, the side cover 201 is pushed by the first photovoltaic panel 303 to both sides of the side cover 201, so that the side of the side cover 201 away from the first photovoltaic panel 303 abuts against the limit block 110, causing the piston rod 203 to squeeze the gas inside the spring 204 and the sealing groove 108. The elastic force of the spring 204 and the air pressure in the sealing groove 108 support the side cover 201, indirectly supporting the first photovoltaic panel 303, improving the stability of the unfolding of the first photovoltaic panel 303 during the unfolding process of the first photovoltaic panel 303, and preventing the situation that the side of the first photovoltaic panel 303 close to the photovoltaic cell 305 is bent backward due to strong wind. At the same time, a restoring force can be provided to the side cover 201 during folding;

[0043] At the same time, during the unfolding process of the first photovoltaic panel 303, the tooth groove 308 on the top of the slider 301 will mesh with the second gear 401. The movement of the slider 301 drives the second gear 401 to rotate. The rotation of the second gear 401 drives the support plate 402 to rotate towards the first photovoltaic panel 303. The rotation of the support plate 402 will successively pass through the two third chutes 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. By the rotation of the support plate 402, a force is applied to the second photovoltaic panel 307, causing the second photovoltaic panel 307 to rotate when the first photovoltaic panel 303 rotates. 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. 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 body housing 101;

[0044] When the second gear 401 rotates, it will drive the third gear 403 to rotate in the opposite direction, so that the limiting plate 404 rotates out of the groove 107 and moves towards the top cover 109 until it abuts 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, avoiding the situation that the side of the second photovoltaic panel 307 close to the photovoltaic cell 305 is bent backward due to strong wind. In the non-working state or during transportation, the device can be folded, which can significantly reduce the floor area, facilitate transportation and storage, and at the same time reduce the maintenance cost. Also, in bad weather, the device can be folded, thus reducing the maintenance cost and increasing the service life of the device.
