Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a photovoltaic-powered charging pile. Background Technology

[0002] With the global energy structure transformation, solar energy has become a key development direction due to its clean and renewable characteristics. The maturity of photovoltaic power generation technology and its continuous cost reduction provide a technological foundation for charging piles. Photovoltaic-powered charging piles use photovoltaics as their core, integrating energy storage, power electronics, and intelligent control to solve the problems of energy sustainability and grid flexibility in electric vehicle charging.

[0003] Existing photovoltaic charging piles typically have photovoltaic panels fixedly mounted on top of the charging pile to obtain the best lighting conditions. Most photovoltaic panels are directly installed on top of the charging pile through brackets, forming a "solar canopy" structure. This method saves space and is suitable for places such as urban streets and small parking lots.

[0004] However, when this type of fixed photovoltaic charging pile is used in the southern coastal areas, there are more typhoons and strong winds. The photovoltaic panels installed are easily blown off or even broken by strong winds, resulting in significant losses to the photovoltaic charging pile. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the fact that the traditional photovoltaic panel installation method is not suitable for the southern coastal areas, this invention is proposed.

[0007] Therefore, the purpose of this invention is to provide a photovoltaic-powered charging pile.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a photovoltaic power supply charging pile, comprising a charging pile, a charging head installed on the outside of the charging pile, and a photovoltaic module installed on the top of the charging pile; A bending connecting frame is connected to the bottom of the charging pile and the side without the charging head.

A rectangular block is installed on the outer wall of the connecting rod. A hinge is provided on the top of the rectangular block. The hinge is fixedly connected to the bottom of the photovoltaic module.

[0009] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, wherein: a movable block is installed at the bottom of the hinge piece, an internal thread block is installed at the bottom of the movable block, the movable block is embedded inside the rectangular block, a rotating shaft is installed on the bottom wall of the rectangular block, a threaded shaft is installed on the top of the rotating shaft, and the threaded shaft is embedded in the internal thread block to achieve thread engagement.

[0010] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, a gear is installed at the bottom of the rotating shaft, and a toothed block is installed on one side of the top position of the bent connecting frame, with the toothed block located on one side of the movement path of the gear.

[0011] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, the top of the bending connecting frame is equipped with a front-end support block, the top of the charging pile is equipped with a rear-end support frame, and the top of the front-end support block and the rear-end support frame are provided with airtight soft pads for contacting the bottom of the photovoltaic module.

[0012] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, a negative pressure block is installed at the top end of the bent connecting frame, a partition plate is installed inside the negative pressure block, and a connecting pipe is provided inside the partition area of ​​the partition plate, which connects the rear support frame and the front support block respectively.

[0013] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, the inner bottom wall of the partition plate is provided with a sealing block by a spring, the sealing block blocks the opening at the bottom of the partition plate, a bent pressure rod is mounted at the bottom of the sealing block, a sealing plate is installed on the inner wall of the negative pressure block, and the sealing plate and the bottom bent section of the bent pressure rod are connected by a connecting rope.

[0014] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, wherein: a rotating pull block is installed on one side of the outer wall of the negative pressure block, one side of the rotating pull block is located on one side of the sealing plate and is movably connected by a telescopic pull rod and a pin, the rotating pull block is located on one side of the center position of the sealing plate, and both sides of the rotating pull block are movably mounted on the negative pressure block by a shaft.

[0015] As a preferred embodiment of the photovoltaic power supply charging pile of the present invention, the rotating block has transmission teeth at both ends of its shaft, and the transmission teeth are embedded in the interior of the negative pressure block sidewall, and the outer wall of the rectangular block is equipped with an embedded transmission plate.

[0017] Beneficial effects The technical solution provided by this invention has the following advantages compared with the known prior art: 1. During typhoon weather, the output motor can move the photovoltaic modules and eventually move them along the bent connecting frame to the back of the charging pile, changing them from "horizontally positioned on top" to "vertically attached to the wall". This significantly reduces the windward area and wind pressure torque, reduces the instantaneous wind load impact by more than 50%, and fundamentally prevents the photovoltaic panels from being overturned or broken, achieving non-destructive protection in high-wind areas and effectively protecting the photovoltaic panels. 2. After the photovoltaic module is moved to the working position, the gear-tooth block meshing immediately triggers the threaded shaft to press down, making the photovoltaic panel tightly fit the airtight soft pads on the front and rear support blocks; then, the embedded transmission plate meshes with the transmission teeth, driving the sealing plate inside the negative pressure block to draw in suction, forming a negative pressure adsorption between the front support block, the rear support frame, and the photovoltaic panel. The dual fixation of mechanical locking and vacuum adsorption means that no manual fixing is required when the photovoltaic module is reset, and the automatic fixing effect is reliable.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

[0030] Example Reference Figures 1-6 This is one embodiment of the present invention. This embodiment provides a photovoltaic power supply charging pile 1, including a charging pile 1, a charging head 11 installed on the outside of the charging pile 1, and a photovoltaic module 12 installed on the top of the charging pile 1. A bending connecting frame 2 is connected to the bottom of the charging pile 1 and the side not connected to the charging head 11. An output motor 21 is installed on the outer wall of the bending connecting frame 2, and a chain assembly 22 is installed at the output end of the output motor 21. A connecting rod 23 is slidably connected inside the bending connecting frame 2, and the end of the connecting rod 23 is connected to the chain assembly 22. A rectangular block 24 is installed on the outer wall of the connecting rod 23, and a hinge piece 25 is provided on the top of the rectangular block 24. The hinge piece 25 is fixedly connected to the bottom of the photovoltaic module 12. The output motor 21 drives the connecting rod 23 through the chain assembly 22, so that the rectangular block 24 drives the hinge piece 25, thereby realizing the bending of the photovoltaic module 12 from the top of the charging pile 1 to the back. The movement of the connecting frame 2 is designed to cope with typhoon weather. When a typhoon is imminent, the output motor 21 drives the chain assembly 22 to rotate. The chain assembly 22 drives the connecting rod 23 to move. The movement of the connecting rod 23 drives the rectangular block 24 to move. The rectangular block 24 drives the hinge 25 connected to the top side by the pin to move. The hinge 25 drives the photovoltaic module 12 at the top to move. The photovoltaic module 12 gradually moves to the non-charging head 11 side of the charging pile 1, and finally moves along the bent connecting frame 2 to the back of the charging pile 1, so that the photovoltaic module 12 stands on one side of the charging pile 1. This reduces the stress on the photovoltaic panel during typhoon weather and effectively protects the photovoltaic panel.

[0031] Specifically, a movable block 3 is installed at the bottom of the hinge piece 25, and an internal threaded block 31 is installed at the bottom of the movable block 3. The movable block 3 is embedded inside the rectangular block 24. A rotating shaft 32 is installed on the bottom wall of the rectangular block 24, and a threaded shaft 34 is installed on the top of the rotating shaft 32. The threaded shaft 34 is embedded in the internal threaded block 31 to achieve thread engagement. When the photovoltaic module 12 moves to the end position, the gear 33 engages with the toothed block 35 to drive the rotating shaft 32 to rotate. The rotation of the threaded shaft 34 causes the internal threaded block 31 to move downward, applying a downward pulling force to the hinge piece 25 to ensure that the bottom of the photovoltaic module 12 is tightly fitted with the support structure.

[0032] Furthermore, a gear 33 is installed at the bottom of the rotating shaft 32, and a toothed block 35 is installed on one side of the top position of the bending connecting frame 2. The toothed block 35 is located on the side of the movement path of the gear 33. When the gear 33 moves with the photovoltaic module 12 to the position of the toothed block 35, the two mesh and trigger the rotating shaft 32 to rotate, providing power to the threaded shaft 34, so as to achieve precise downward pressing and fixing of the photovoltaic module 12. When the photovoltaic module 12 moves closer to the end position, its gear 33 moves to the side of the toothed block 35. At this time, the toothed block 35 drives the gear 33 to rotate. The rotation of the gear 33 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the threaded shaft 34 to rotate. The rotation of the threaded shaft 34 drives the internal threaded block 31 to move. The internal threaded block 31 moves downward and applies a downward pulling force to the hinge piece 25, thereby applying a downward pulling force to the photovoltaic module 12, so that the bottom of the photovoltaic module 12 is completely in contact with the top of the front support block 4 and the rear support frame 41.

[0033] Furthermore, a front support block 4 is installed on the top of the bending connection frame 2, and a rear support frame 41 is installed on the top of the charging pile 1. The top of the front support block 4 and the rear support frame 41 are provided with airtight soft pads for contacting the bottom of the photovoltaic module 12. When the photovoltaic module 12 is reset, the airtight soft pads are tightly attached to its bottom, and with the subsequent negative pressure adsorption, a sealed support surface is formed to enhance the fixation stability.

[0034] Furthermore, a negative pressure block 5 is installed at the top end of the bending connecting frame 2. A partition plate 52 is installed inside the negative pressure block 5. A connecting pipe 51 is provided inside the partition area of ​​the partition plate 52. The connecting pipe 51 connects the rear support frame 41 and the front support block 4 respectively. The movement of the sealing plate 55 causes negative pressure to be generated in the area of ​​the partition plate 52. The negative pressure is conducted to the top of the support block through the connecting pipe 51, which adsorbs and fixes the photovoltaic module 12 and moves the module.

[0035] Furthermore, the inner bottom wall of the partition plate 52 is provided with a sealing block 53 via a spring. The sealing block 53 blocks the opening at the bottom of the partition plate 52. A bent pressure rod 54 is mounted at the bottom of the sealing block 53. A sealing plate 55 is installed on the inner wall of the negative pressure block 5. The sealing plate 55 is connected to the bottom bent section of the bent pressure rod 54 via a connecting rope 56. The movement of the sealing plate 55 pulls the bent pressure rod 54 via the taut connecting rope 56, causing its raised end to lift the sealing block 53, opening the negative pressure channel and triggering the adsorption and fixation function.

[0036] Furthermore, a rotating pull block 57 is installed on one side of the outer wall of the negative pressure block 5. One side of the rotating pull block 57 is located on one side of the sealing plate 55 and is movably connected by a telescopic pull rod and a pin. The rotating pull block 57 is located on one side of the center position of the sealing plate 55. Both sides of the rotating pull block 57 are movably mounted on the negative pressure block 5 through shafts. The rotating pull block 57 rotates under the drive of the transmission gear 58 and pulls the sealing plate 55 to move through the telescopic pull rod, providing power for negative pressure adsorption and ensuring the accurate stroke of the sealing plate 55.

[0037] Furthermore, both ends of the shaft of the rotating pull block 57 are provided with transmission teeth 58, and the transmission teeth 58 are embedded in the interior of the side wall of the negative pressure block 5. The outer wall of the rectangular block 24 is equipped with an embedded transmission plate 59. When the embedded transmission plate 59 moves to the end with the rectangular block 24, it meshes with the transmission teeth 58, drives the rotating pull block 57 to rotate, and converts the linear motion of the rectangular block 24 into the movement of the sealing plate 55, triggering the negative pressure fixing.

[0038] Furthermore, when the embedded transmission plate 59 moves to the bottom end position of the bent connecting frame 2, the embedded transmission plate 59 can be embedded into the rectangular block 24, and the toothed groove at the bottom of the embedded transmission plate 59 can mesh with the transmission teeth 58. This causes the transmission teeth 58 to rotate. The meshing of the embedded transmission plate 59 and the transmission teeth 58 is the key to triggering the negative pressure fixing system, ensuring that the photovoltaic module 12 automatically starts adsorption fixing after being moved into place, without the need for an additional power source. When the rectangular block 24 approaches the end, its embedded transmission plate 59 contacts the transmission teeth 58 and drives the transmission teeth 58 to rotate. The rotation of the transmission teeth 58 drives the rotating pull block. Rotating the rotating block 57 causes the sealing plate 55 to move. The movement of the sealing plate 55 gradually creates negative pressure on one side. After the sealing plate 55 is in place, it pulls the bent contact rod 54 through the taut connecting rope 56. One end of the bent contact rod 54 tilts upward, and the tilted end of the bent contact rod 54 lifts the sealing block 53. This causes the negative pressure of the partition plate 52 to be transmitted through the connecting pipe 51 to the top area of ​​the front support block 4 and the rear support frame 41. As a result, the photovoltaic module 12 is attracted to the top of the front support block 4 and the rear support frame 41 by the negative pressure, thus completing the automatic fixation of the photovoltaic module 12.

[0039] Operation process: The photovoltaic panel is located on top of the charging pile 1, supported by the front support block 4 and the rear support frame 41. The rectangular block 24 and hinge 25 connected by the chain assembly 22 guide and position the photovoltaic module 12. When facing typhoon weather, the output motor 21 drives the chain assembly 22 to rotate. The chain assembly 22 drives the connecting rod 23 to move. The movement of the connecting rod 23 drives the rectangular block 24 to move. The rectangular block 24 drives the hinge 25 connected by the pin on the top side to move. The hinge 25 drives the photovoltaic module 12 on the top to move. The photovoltaic module 12 gradually moves towards the non-charging head 11 side of the charging pile 1, and finally moves along the bend. The connecting frame 2 moves to the back of the charging pile 1, causing the photovoltaic module 12 to stand upright on one side of the charging pile 1. This reduces the stress on the photovoltaic panel during typhoons and effectively protects it. When it needs to be put back into use, the output motor 21 drives the chain assembly 22 to move back to its original position. The movement of the chain assembly 22 lifts the photovoltaic module 12 upwards again, ultimately allowing it to be supported by the front support block 4 and the rear support frame 41. As the photovoltaic module 12 moves closer to its end position, its gear 33 moves to the side of the tooth block 35. At this time, the tooth block 35 drives the gear 33 to rotate, which in turn drives the rotating shaft 32 to rotate. The rotating shaft 32 then drives the threaded... The rotation of shaft 34 causes the internal thread block 31 to move. The downward movement of the internal thread block 31 applies a downward pulling force to the hinge plate 25, thereby applying a downward pulling force to the photovoltaic module 12. This causes the bottom of the photovoltaic module 12 to completely contact the top of the front support block 4 and the rear support frame 41. When the rectangular block 24 approaches the end, its embedded transmission plate 59 contacts the transmission gear 58, causing the transmission gear 58 to rotate. The rotation of the transmission gear 58 causes the rotating pull block 57 to rotate, which in turn causes the sealing plate 55 to move. The movement of the sealing plate 55 gradually creates negative pressure on one side of the sealing plate 55. After the sealing plate 55 moves into position, the seal... The plate 55 pulls the bent contact rod 54 through the taut connecting rope 56. One end of the bent contact rod 54 tilts upward, and the tilted end of the bent contact rod 54 pushes up the sealing block 53. This allows the negative pressure of the partition plate 52 to be transmitted through the connecting pipe 51 to the top area of ​​the front support block 4 and the rear support frame 41. As a result, the photovoltaic module 12 is attracted to the top of the front support block 4 and the rear support frame 41 by the negative pressure, thus completing the automatic fixation of the photovoltaic module 12. Through this structure, the top of the photovoltaic module 12 can be quickly moved to the side, which is convenient for maintenance and cleaning, and also reduces the impact on the photovoltaic module 12 during typhoon weather, effectively improving the performance.
