When a vehicle needs to be charged, the electrical energy in the energy storage battery is processed by the circuit inside the pile body, and the charging voltage and current adapted to the vehicle are output to charge the vehicle.

[0004] In the process of implementing this application, it was found that there are at least the following problems in this technology: regardless of whether it is sunny or cloudy, the photovoltaic panels are exposed to the outside all day long, and on cloudy days, the photovoltaic panels cannot collect energy, and cloudy days may be accompanied by harsh environmental conditions, such as rain, snow and even hail, which can easily cause damage to the photovoltaic panels and affect the service life of the charging piles. Summary of the invention

[0005] In order to facilitate the folding of photovoltaic panels, prevent bad weather from damaging the photovoltaic panels, and extend the service life of the charging pile, the present application provides a charging pile with photovoltaic energy storage.

[0006] The present application provides a charging pile with photovoltaic energy storage using the following technical solution: A charging pile with photovoltaic energy storage, comprising a pile body, a storage box with a top opening fixed on the pile body, a sliding bracket slidably arranged in the vertical direction in the storage box, a sliding mechanism for driving the sliding bracket to slide in the storage box, a cover plate fixedly arranged on the top of the sliding bracket, the cover plate can close the opening of the storage box; a group of support rods extending downward are symmetrically and fixedly arranged on the cover plate, and a movable pin is fixedly arranged at the bottom of the support rod in the horizontal direction; a sliding bracket is slidably arranged in the vertical direction in the storage box There is a movable block, on which a group of rotating supports are symmetrically and fixedly arranged, the rotating supports correspond to the support rods one by one, and a mounting plate frame is jointly arranged on the rotating support and the support rod, on which a photovoltaic panel is fixedly installed, and one end of the two mounting plate frames close to each other is rotatably connected to the support, and a sliding groove is opened on the side wall of the mounting plate frame, and the movable pin rotates and slides in the sliding groove; a locking mechanism is arranged in the storage box, and the locking mechanism is used to lock the movable block to prevent the movable block from approaching the bottom of the storage box.

[0007] By adopting the above technical solution, on sunny days, the sliding bracket is first driven upward by the sliding mechanism, thereby driving the cover plate to move upward. At this time, the movable pin and the rotating support are separated from each other in the height direction, and the movable pin slides and rotates in the slide groove, so that the mounting plate frame and the photovoltaic panel on the mounting plate frame rotate around the rotating support, and the mounting plate frame tends to be in a vertical state; then, the locking mechanism releases the lock on the movable block, and the movable block is allowed to move downward and close to the bottom of the storage box; then, the sliding bracket is driven downward by the sliding mechanism, and the cover plate and the movable block move downward together. Therefore, the mounting plate frame and the photovoltaic panel on the mounting plate frame remain in a vertical state and enter the storage box, so that the photovoltaic panel can be folded up, prevent bad weather from damaging the photovoltaic panel, and extend the service life of the charging pile. On sunny days, the sliding mechanism is used to drive the sliding bracket upward, thereby driving the cover plate upward, and the movable pin pulls the top of the vertical slide slot, and the mounting plate frame and the movable block at the bottom of the mounting plate frame move upward accordingly, so that the mounting plate frame tending to be in a vertical state is separated from the storage box; then, the locking mechanism is used to lock the movable block to limit the downward movement of the movable block; then, the sliding mechanism is used to drive the sliding bracket downward, and at this time, the movable pin and the rotating support are close to each other in the height direction, so that the mounting plate frame rotates around the rotating support, and the mounting plate frame tends to be in a horizontal state, so that the photovoltaic panel is unfolded. In this way, it is easy to realize the unfolding and storage of the photovoltaic panel.

[0008] Preferably, the sliding mechanism includes a motor and a screw, the screw is vertically and rotatably arranged in a storage box, the sliding bracket is threadedly engaged with the screw, the motor is fixedly arranged in the storage box, and the driving shaft of the motor is coaxially connected to the screw.

[0009] By adopting the above technical solution, when the motor is working, the driving shaft of the motor drives the screw to rotate, and the screw is threadedly engaged with the sliding bracket, so that the rotation of the screw is converted into the vertical sliding movement of the sliding bracket, thereby realizing the stable lifting and self-locking of the sliding bracket.

[0010] Preferably, a light sensor is fixedly mounted on the top of the cover plate, and the light sensor is electrically connected to the motor.

[0011] By adopting the above technical solution, the light sensor can detect the external light intensity in real time and transmit the detected signal to the motor. When the light intensity is lower than the set value, the motor starts and the photovoltaic panel is folded; when the light intensity is higher than the set value, the motor starts again and the photovoltaic panel is unfolded. In this way, the folding and unfolding of the photovoltaic panel is automatically controlled according to the light conditions, which improves the intelligence and convenience of the charging pile.

[0012] Preferably, a return spring is provided in the storage box, the top end of the return spring is fixedly connected to the bottom of the movable block, the bottom end of the return spring is fixedly connected to the inner bottom wall of the storage box, and the return spring drives the movable block close to the bottom of the storage box.

[0013] By adopting the above technical solution, when the locking mechanism releases the lock on the movable block, the return spring provides assistance for the movable block to move downward, making the storage action of the photovoltaic panel smoother and preventing the movable block from getting stuck when sliding downward.

[0014] Preferably, the locking mechanism includes a block, a connecting frame, a flip shaft, a return plate, and a flip assembly, the block is fixedly arranged on the side wall of the movable block, the connecting frame is fixedly connected to the storage box, the flip shaft is arranged in the horizontal direction and rotates on the connecting frame, the return plate is fixedly connected to the flip shaft, the top of the return plate on the side facing the movable block is abutted against the bottom of the block, and the return plate 54 is provided with a passing groove in the vertical direction on the side away from the movable block for the block to pass through, and the flip assembly is used to drive the flip shaft to rotate and lock the flip shaft.

[0015] By adopting the above technical solution, when the lock needs to be released, the flip assembly drives the flip shaft to rotate 180 degrees, driving the anti-return plate to flip, so that the through slot of the anti-return plate faces the movable block, and the block can move down through the through slot. When the movable block needs to be locked, the flip assembly drives the flip shaft to rotate again, so that the through slot of the anti-return plate is away from the movable block, and the anti-return plate abuts against the bottom of the block to prevent the movable block from moving down. In this way, the locking and unlocking actions of the movable block are quickly achieved.

[0016] Preferably, the flip assembly includes a rotating disk, a ratchet, a propulsion pawl, a first torsion spring, a check piece, and a driving piece. The ratchet is coaxial with the flip axis and fixedly connected, the rotating disk is coaxial with the flip axis and rotatably connected, the propulsion pawl is rotatably arranged on the end face of the rotating disk, the first torsion spring is arranged between the propulsion pawl and the rotating disk, the first torsion spring drives the propulsion pawl to abut against the ratchet teeth of the ratchet, the driving piece is used to drive the rotating disk to rotate, and the check piece is used to prevent the ratchet from pushing the rotating disk to rotate.

[0017] By adopting the above technical solution, the push pawl is against the ratchet wheel under the action of the first torsion spring. When the flip shaft needs to be driven to rotate, the driving member drives the rotating disk to rotate, and the push pawl rotates with the rotating disk and pushes the ratchet wheel to rotate, thereby driving the flip shaft to rotate and realizing the flipping of the anti-return plate. The anti-return member prevents the ratchet wheel from pushing the rotating disk to rotate in the opposite direction through the push pawl, ensuring the one-way flipping action and ensuring the accuracy and stability of the locking and unlocking operations.

[0018] Preferably, the driving member includes a rack and a gear, the rack is vertically and fixedly arranged on the side wall of the sliding bracket close to the bottom, the gear is fixedly connected to the rotating disk, and the rack can mesh with the gear.

[0019] By adopting the above technical solution, in the process of unfolding the photovoltaic panel, the sliding bracket moves up, and the rack moves up accordingly. The sliding bracket pulls the movable block up, and after the block passes over the passing groove of the return plate, the sliding bracket continues to move up, and the rack and gear enter into meshing and drive the rotating disk to rotate in one direction. At this time, the pushing pawl does not push the ratchet to rotate; and when the sliding bracket moves down, the rack and gear mesh and drive the rotating disk to rotate in another direction. At this time, the pushing pawl pushes the ratchet to rotate, and the ratchet drives the return plate to rotate 180 degrees through the flip shaft, so that the passing groove moves away from the movable block. During the process of storing the photovoltaic panels, the sliding bracket moves up and the rack moves up accordingly. When the mounting plate rack tends to be vertical, the sliding bracket begins to pull the movable block up, and the rack and gear mesh again and drive the rotating disk to rotate in one direction. At this time, the advancing pawl does not push the ratchet to rotate; and when the sliding bracket moves down, the rack and gear mesh and drive the rotating disk to rotate in another direction. At this time, the advancing pawl pushes the ratchet to rotate, and the ratchet drives the return plate to rotate 180 degrees through the flip shaft, so that the through slot faces the movable block.

[0020] Preferably, the non-return member includes a non-return pawl and a second torsion spring. The non-return pawl is rotatably arranged on the connecting frame. The second torsion spring is arranged between the connecting frame and the non-return pawl. The second torsion spring drives the non-return pawl to abut against the ratchet teeth of the ratchet wheel.

[0021] By adopting the above technical solution, the non-return pawl contacts the ratchet teeth of the ratchet wheel under the action of the second torsion spring, preventing the ratchet wheel from rotating in the opposite direction, thereby ensuring that the ratchet wheel can only rotate in one direction under the push of the thrust pawl, further ensuring the accuracy and stability of the flipping action of the anti-return plate.

[0022] Preferably, a brush plate is fixedly mounted on the cover plate, and bristles are arranged on the bottom of the brush plate, and the bristles are against the surface of the photovoltaic panel.

[0023] By adopting the above technical solution, when the cover plate drives the movable pin to slide in the slide groove, the photovoltaic panel and the bristles of the brush plate come into contact and move relative to each other. At this time, the bristles can clean the surface of the photovoltaic panel, remove dust, debris, etc., keep the surface of the photovoltaic panel clean, and improve the degree of exposure of the photovoltaic panel.

[0024] Preferably, a mounting groove is provided at the bottom of the cover plate, the brush plate is inserted in the mounting groove, a locking pin is slidably provided in a horizontal direction on the side wall of the cover plate and extends into the mounting groove, and a lock groove for inserting the locking pin is provided on the side wall of the mounting groove.

[0025] By adopting the above technical solution, when the brush plate needs to be installed, the brush plate is inserted into the installation slot, and then the locking pin is pushed to insert the locking pin into the locking slot, thereby achieving fixed installation of the brush plate. When the brush plate needs to be replaced or repaired, the locking pin is slid in the opposite direction to disengage the locking slot, and the brush plate can be taken out of the installation slot. This facilitates the disassembly and assembly of the brush plate, and is conducive to the regular replacement of the brush plate.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The present application embodiment discloses a charging pile with photovoltaic energy storage. Figures 1 to 3 The invention comprises a pile body 1, on which a storage box 2 with an opening at the top is fixedly arranged. A sliding bracket 21 is arranged in the storage box 2 for sliding along the vertical direction, and a sliding mechanism 3 for driving the sliding bracket 21 to slide is arranged in the storage box 2. A cover plate 22 is fixedly arranged on the top of the sliding bracket 21, and the cover plate 22 can close the opening of the storage box 2. A group of support rods 222 extending downward are symmetrically and fixedly arranged on the cover plate 22, and a movable pin 2221 is fixedly arranged at the bottom of the support rods 222 along the horizontal direction.

[0035] Reference Figure 1 and Figure 3A movable block 23 is provided in the storage box 2 for sliding in the vertical direction. A set of rotating supports 232 are symmetrically and fixedly provided on the top of the movable block 23. The rotating supports 232 correspond to the support rods 222 one by one. A mounting plate frame 4 is provided on the rotating supports 232 and the support rods 222. The mounting plate frame 4 is parallel to the horizontal plane. A photovoltaic panel 41 is fixedly installed on the mounting plate frame 4. The photovoltaic panel 41 is located on the upper surface of the mounting plate frame 4. The ends of the two mounting plate frames 4 that are close to each other are rotatably connected to the support. A slide groove 42 is provided on the side wall of the mounting plate frame 4 in the horizontal direction. The movable pin 2221 rotates and slides in the slide groove 42. A locking mechanism 5 is provided on the inner wall at the top of the storage box 2. The locking mechanism 5 is used to lock the movable block 23 to prevent the movable block 23 from approaching the bottom of the storage box 2. A return spring 231 is provided in the storage box 2 , the top of the return spring 231 is fixedly connected to the bottom of the movable block 23 , and the bottom of the return spring 231 is fixedly connected to the inner bottom wall of the storage box 2 , and the return spring 231 drives the movable block 23 close to the bottom of the storage box 2 .

[0036] In order to realize the automatic folding of the photovoltaic panel 41 on cloudy days and the unfolding on sunny days, refer to Figure 2 The sliding mechanism 3 includes a motor 31 and a screw rod 32. The screw rod 32 is vertically and rotatably arranged in the storage box 2. The sliding bracket 21 is threadedly engaged with the screw rod 32. The motor 31 is fixedly arranged in the storage box 2. The driving shaft of the motor 31 is coaxially connected with the screw rod 32. A light sensor 221 is fixedly mounted on the top of the cover plate 22. The light sensor 221 is electrically connected to the motor 31 through a processor. The processor can be a PLC controller, and the motor 31 is a servo motor.

[0037] Reference Figures 1 to 3, the light sensor 221 detects the external light intensity in real time. When the light intensity drops below the set value, it is considered that the external light changes from sunny to cloudy. At this time, the processor controls the motor 31 to retract the photovoltaic panel 41. The motor 31 drives the screw rod 32 to rotate in the forward direction, and the screw rod 32 engages the sliding bracket 21 and drives the sliding bracket 21 to move up, thereby driving the cover plate 22 and the movable pin 2221 to move up. When the movable pin 2221 moves up, it moves away from the rotating support 232 in the height direction. The movable pin 2221 slides and rotates in the slide groove 42, so that the mounting plate frame 4 and the photovoltaic panel 41 rotate around the rotating support 232 until the movable pin 2221 moves to the end of the slide groove 42 away from the rotating support 232. At this moment, the slide groove 42 and the mounting plate frame 4 tend to be vertical. Then, the locking mechanism 5 releases the lock on the movable block 23, and the movable block 23 is allowed to move down. Finally, the motor 31 drives the screw rod 32 to rotate in the opposite direction, and the screw rod 32 drives the sliding bracket 21 and the cover plate 22 to move downward, and the movable pin 2221 moves downward accordingly and loosens the end of the slide groove 42. Under the action of the reset spring 231, the mounting plate frame 4 and the movable block 23 move downward together with the cover plate 22. Therefore, the mounting plate frame 4 and the photovoltaic panel 41 remain in a vertical state and are stored in the storage box 2 until the cover plate 22 abuts against the top of the storage box 2, thereby closing the opening of the storage box 2. In this way, the photovoltaic panel 41 is put away to prevent the photovoltaic panel 41 from being damaged by bad weather, thereby extending the service life of the charging pile.

[0038] Reference Figures 1 to 3 When the light intensity rises to a value higher than the set value, it means that the outside world changes from a cloudy day to a sunny day. At this time, the processor controls the motor 31 to unfold the photovoltaic panel 41. The motor 31 drives the screw rod 32 to rotate in the forward direction, and the screw rod 32 drives the sliding bracket 21 to move up, thereby driving the cover plate 22 and the movable pin 2221 to move up. The movable pin 2221 pulls the end of the vertical slide 42. At this time, the cover plate 22, the mounting plate frame 4, and the movable block 23 move up together, so that the mounting plate frame 4 that is kept in a vertical state leaves the storage box 2. Then, the locking mechanism 5 locks the movable block 23, and the movable block 23 cannot move down. Finally, the motor 31 drives the screw rod 32 to rotate in the opposite direction, driving the sliding bracket 21 and the cover plate 22 to move down, the movable pin 2221 moves down and approaches each other with the rotating support 232 in the height direction, and the movable pin 2221 slides and rotates in the slide 42, and the mounting plate frame 4 tends to be horizontal, thereby unfolding the photovoltaic panel 41.

[0039] In order to facilitate locking of the movable block 23, refer to Figures 1 to 4The locking mechanism 5 includes a stopper 51, a connecting frame 52, a flip shaft 53, a return plate 54, and a flip assembly 55. The stopper 51 is fixedly arranged on the side wall of the movable block 23. The connecting frame 52 is fixedly connected to the storage box 2, and the flip shaft 53 is arranged in the horizontal direction and rotates on the connecting frame 52. The return plate 54 is fixedly connected to the flip shaft 53, and the top of the return plate 54 facing the movable block 23 is against the bottom of the stopper 51, and the side of the return plate 54 away from the movable block 23 is provided with a through groove 541 in the vertical direction for the stopper 51 to pass through in the vertical direction. The flip assembly 55 is used to drive the flip shaft 53 to rotate and lock the flip shaft 53.

[0040] In order to automatically drive the flip shaft 53 to rotate and lock the flip shaft 53, refer to Figures 2 to 4 The flip assembly 55 includes a rotating disk 551, a ratchet 552, a propulsion pawl 553, a first torsion spring 554, a check piece 555, and a driving piece 556. The ratchet 552 is coaxial with and fixedly connected to the flip shaft 53, and the rotating disk 551 is coaxial with and rotatably connected to the flip shaft 53. The propulsion pawl 553 is rotatably arranged on the end surface of the rotating disk 551, and the first torsion spring 554 is arranged between the propulsion pawl 553 and the rotating disk 551. The first torsion spring 554 drives the propulsion pawl 553 to abut against the ratchet teeth of the ratchet 552. The driving piece 556 is used to drive the rotating disk 551 to rotate, and the check piece 555 is used to prevent the ratchet 552 from pushing the rotating disk 551 to rotate.

[0041] Reference Figures 2 to 4 The driving member 556 includes a rack 5561 and a gear 5562. The rack 5561 is vertically and fixedly arranged on the side wall of the sliding bracket 21 near the bottom. The gear 5562 is integrally formed with the rotating disk 551. The rack 5561 can mesh with the gear 5562. The non-return member 555 includes a non-return pawl 5551 and a second torsion spring 5552. The non-return pawl 5551 is rotatably arranged on the connecting frame 52 ( Figure 3 It is shown in Figure 4 The second torsion spring 5552 is disposed between the connecting frame 52 and the non-return pawl 5551, and the second torsion spring 5552 drives the non-return pawl 5551 to abut against the ratchet teeth of the ratchet wheel 552. In addition, in this embodiment, a stabilizing pressing block 225 is fixedly disposed at the bottom of the cover plate 22, and when the photovoltaic panel 41 is in the unfolded state, the stabilizing pressing block 225 abuts against the top of the movable block 23.

[0042] Reference Figures 2 to 4In the process of storing the photovoltaic panel 41, the sliding bracket 21 first drives the rack 5561 to move upward. When the mounting plate frame 4 tends to be vertical (i.e., the movable pin 2221 is located at the end of the slide slot 42 away from the rotating support 232), the rack 5561 begins to contact the gear 5562. Then, the sliding bracket 21 continues to move upward, and the movable pin 2221 pulls the mounting plate frame 4 and the movable block 23 to move upward for a distance, providing a movable space for the return plate 54. At the same time, the rack 5561 meshes with the gear 5562 and drives the rotating disk 551 to rotate forward, and the ratchet 553 is pushed to not drive the ratchet 552 to rotate. Then the sliding bracket 21 is driven to move downward, the rack 5561 meshes with the gear 5562 and drives the rotating disk 551 to rotate in the opposite direction, pushing the pawl 553 to push the ratchet 552 to rotate, and the ratchet 552 drives the return plate 54 to rotate 180 degrees through the flip shaft 53, so that the through slot 541 faces the movable block 23, and the stop block 51 passes over the return plate 54 through the through slot 541.

[0043] Reference Figures 2 to 4 In the process of unfolding the photovoltaic panel 41, the sliding bracket 21 first drives the rack 5561 to move upward, and the sliding bracket 21 pulls the movable block 23 to move upward. After the block 51 passes over the through slot 541 of the anti-return plate 54, the sliding bracket 21 continues to move upward, the rack 5561 and the gear 5562 enter into meshing and drive the rotating disk 551 to rotate forward, and the advancing pawl 553 does not push the ratchet 552 to rotate. Then, the sliding bracket 21 is driven to move downward, the rack 5561 and the gear 5562 are meshed and drive the rotating disk 551 to rotate in the opposite direction, and the advancing pawl 553 pushes the ratchet 552 to rotate, and the ratchet 552 drives the anti-return plate 54 to rotate 180 degrees again through the flip shaft 53, and then the gear 5562 and the rack 5561 are disengaged, so that the through slot 541 is away from the movable block 23. The sliding bracket 21 continues to move downward, and the anti-return plate 54 abuts against the bottom of the block 51 to prevent the movable block 23 from moving downward. The movable pin 2221 is close to the rotating support 232, and the mounting plate frame 4 tends to be horizontal. At this time, the photovoltaic panel 41 is unfolded, and the stabilizing block 225 moves to abut against the top of the movable block 23. The bottom of the movable block 23 is constrained by the return plate 54, and the top is constrained by the stabilizing block 225. Before the sliding bracket 21 slides, the movable block 23 cannot slide, further ensuring the stability of the photovoltaic panel 41. In summary, the flip shaft 53 is automatically driven to rotate and the flip shaft 53 is locked.

[0044] To keep the surface of the photovoltaic panel 41 clean, refer to Figure 2A brush plate 224 is fixedly mounted on the cover plate 22, and bristles 2244 are arranged at the bottom of the brush plate 224, and the bristles 2244 abut against the surface of the photovoltaic panel 41. When the cover plate 22 drives the movable pin 2221 to slide in the slide groove 42, the photovoltaic panel 41 contacts and moves relatively with the bristles 2244 of the brush plate 224, and the bristles 2244 can clean the surface of the photovoltaic panel 41, remove dust, debris, etc., keep the surface of the photovoltaic panel 41 clean, and improve the degree of exposure of the photovoltaic panel 41.

[0045] Reference Figure 2 and Figure 5 , a mounting groove 223 is provided at the bottom of the cover plate 22, and the brush plate 224 is inserted into the mounting groove 223. A lock pin 2241 is provided on the side wall of the cover plate 22 to slide in the horizontal direction and extend into the mounting groove 223. A lock groove 2242 for inserting the lock pin 2241 is provided on the side wall of the mounting groove 223. An insertion spring 2243 is also provided on the lock pin 2241, and the insertion spring 2243 drives the lock pin 2241 to approach the lock groove 2242. When the brush plate 224 needs to be installed, the lock pin 2241 is moved away from the lock groove 2242, the brush plate 224 is inserted into the mounting groove 223, and then the lock pin 2241 is released. Under the action of the insertion spring 2243, the lock pin 2241 is reset and automatically inserted into the lock groove 2242, and the lock pin 2241 fixes the brush plate 224. It is convenient to install or replace the brush plate 224, and ensure the cleanliness of the bristles 2244.

[0046] The implementation principle of a charging pile with photovoltaic energy storage in the embodiment of the present application is as follows: the light sensor 221 detects the light intensity of the outside world in real time. When the light intensity drops below the set value, it means that the outside world changes from sunny to cloudy. At this time, the processor controls the motor 31 to move to retract the photovoltaic panel 41. The motor 31 first causes the screw rod 32 to rotate in the positive direction, driving the sliding bracket 21, the cover plate 22, and the movable pin 2221 to move up. When the movable pin 2221 moves up, it moves away from the rotating support 232 in the height direction until the movable pin 2221 moves to the end of the slide 42 away from the rotating support 232. At this time, the mounting plate frame 4 tends to be vertical, and in this process, the photovoltaic panel 41 contacts and moves relative to the bristles 2244, and the bristles 2244 clean the surface of the photovoltaic panel 41. The sliding bracket 21 continues to move upward, and the movable pin 2221 pulls the mounting plate frame 4 and the movable block 23 to move upward for a distance, providing a movable space for the flipping of the anti-return plate 54. In this process, the rack 5561 meshes with the gear 5562 and drives the rotating disk 551 to rotate forward, and the advancing pawl 553 does not push the ratchet 552 to rotate. Then, the motor 31 drives the sliding bracket 21 to move downward, the rack 5561 meshes with the gear 5562 and drives the rotating disk 551 to rotate in the opposite direction, and the advancing pawl 553 pushes the ratchet 552 to rotate, and the ratchet 552 drives the anti-return plate 54 to rotate 180 degrees through the flip shaft 53, and the through slot 541 of the anti-return plate 54 faces the movable block 23. At the same time, the movable pin 2221 moves downward and relaxes the end of the slide slot 42. Under the action of the reset spring 231, the cover plate 22, the mounting plate frame 4, and the movable block 23 move downward together, and the stopper 51 can pass over the anti-return plate 54 through the through slot 541. Therefore, the mounting frame 4 and the photovoltaic panel 41 are kept in a vertical state and gradually enter the storage box 2 until the cover plate 22 closes the opening of the storage box 2. When it is not sunny, the photovoltaic panel 41 cannot absorb light energy and generate electricity, so the photovoltaic panel 41 is put away to prevent the photovoltaic panel 41 from being damaged by bad weather and extend the service life of the charging pile.

[0047] When the light intensity rises to a value higher than the set value, it means that the external light changes from a cloudy day to a sunny day. At this time, the processor controls the motor 31 to unfold the photovoltaic panel 41. The motor 31 drives the sliding bracket 21, the cover plate 22 and the movable pin 2221 to move upward, and the movable pin 2221 pulls the end of the slide groove 42 in a vertical state. At this time, the cover plate 22, the mounting plate frame 4, and the movable block 23 move upward together, so that the mounting plate frame 4 that remains in a vertical state leaves the storage box 2. After the block 51 passes over the through slot 541 of the return plate 54, the sliding bracket 21 continues to move upward, the rack 5561 and the gear 5562 enter into meshing and drive the rotating disk 551 to rotate forward, and the advancing pawl 553 does not drive the ratchet 552 to rotate. Next, the motor 31 drives the sliding bracket 21 to move downward, the rack 5561 meshes with the gear 5562 and drives the rotating disk 551 to rotate in the opposite direction, pushing the pawl 553 to push the ratchet 552 to rotate, and the ratchet 552 drives the return plate 54 to rotate 180 degrees again through the flip shaft 53, and then the gear 5562 disengages from the rack 5561, so that the groove 541 is away from the movable block 23. The sliding bracket 21 continues to move downward, and the return plate 54 abuts against the bottom of the stop block 51, preventing the movable block 23 from moving downward. The movable pin 2221 continues to move downward and approaches the rotating support 232 in the height direction. The movable pin 2221 slides and rotates in the slide slot 42, and the mounting plate frame 4 tends to be horizontal, thereby unfolding the photovoltaic panel 41. The stabilizing pressing block 225 moves to abut against the top of the movable block 23 , and the movable block 23 is constrained between the stabilizing pressing block 225 and the anti-return plate 54 , so that the movable block 23 cannot slide, thereby ensuring the stability of the unfolding of the photovoltaic panel 41 .

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
