Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to an energy storage DC charging pile with multi-source coordinated power supply. Background Technology

[0002] With the popularization of new energy vehicles, traditional DC charging piles draw power directly from the grid, resulting in high instantaneous power. This can easily cause overload and voltage fluctuations during peak electricity consumption and in areas with limited grid capacity, affecting grid stability. However, energy storage DC charging piles can store electricity during off-peak hours and discharge during peak hours, effectively shaving off peaks and filling valleys and alleviating grid pressure, and are gradually becoming the mainstream solution.

[0003] Existing charging pile cables are often exposed and suspended, making them susceptible to sun and rain, dust and water intrusion, which accelerates cable aging. After charging, the cables are often left on the ground haphazardly, making them easy to be crushed or scratched, posing safety hazards such as leakage and short circuits. Furthermore, the cables cannot be stored in an orderly manner and are easily tangled and pulled, resulting in a high equipment failure rate and maintenance costs. Summary of the Invention

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Example 1, referring to Figure 1 - Figure 2 The first embodiment of the present invention provides an energy storage DC charging pile with multi-source coordinated power supply. The device includes: a charging pile 1, a shrinking unit 2 fixedly installed inside the charging pile 1 for storing and organizing the charging unit 4, a guide unit 3 rotatably installed on the shrinking unit 2 for guiding the shrinking of the charging unit 4 in conjunction with the shrinking unit 2, and a charging unit 4 fixedly installed on the charging pile 1; the guide unit 3 is rotatably connected to the charging pile 1 to ensure normal charging.

[0032] The retraction unit 2 includes a retraction component 21 fixedly installed on the inner wall of the charging pile 1 for adjusting and storing the electric gun assembly 41; the guide unit 3 includes a guide component 31 rotatably installed on the inner wall of the charging pile 1 and cooperating with the retraction component 21 to transport the electric gun assembly 41; the charging unit 4 includes an electric gun assembly 41 slidably installed on the charging pile 1 and a closure 42 fixedly installed on the charging pile 1 and cooperating with the retraction component 21 to allow the electric gun assembly 41 to be stretched and charged normally.

[0033] In use, first open charging station 1 by scanning a code or other means. At this time, the closing member 42 unlocks. Pull the closing member 42 upward to remove the electric gun assembly 41 and pull it outward. During the pulling process, the pulling force of the electric gun assembly 41 will cause the retracting component 21 to squeeze and rotate. The guide component 31 also moves synchronously with the rotation of the retracting component 21, coordinating with the movement of the electric gun assembly 41 to complete the charging operation. At the same time, the retracting component 21 can limit the extension length of the electric gun assembly 41, effectively preventing wear and tear on the ground due to excessive extension. After charging is completed, the owner pulls out the electric gun assembly 41 and pulls it again to release the retracting component 21 from the squeezed state, and then rotates in the opposite direction to begin retracting the electric gun assembly 41. The guide component 31 also rotates synchronously with the rotation of the retracting component 21, arranging the electric gun assembly 41's wiring during the retraction process to prevent tangling. After the retracting component 21 has been completely retracted and the electric gun assembly 41 has returned entirely inside charging station 1, close the closing member 42 to complete the entire charging process.

[0034] By retracting and concealing the electric gun assembly 41 inside the charging pile 1, the aging problems caused by long-term exposure of cables to sunlight and rain, as well as the intrusion of dust and water, can be avoided. This also eliminates the safety hazards such as leakage and short circuits caused by cables being crushed or scratched when placed on the ground. At the same time, it prevents cable tangling, pulling, and knotting, reducing equipment failure rate and subsequent maintenance costs, improving the operational stability and service life of the charging pile. The overall structure is simple and reliable, easy to operate, and effectively enhances the safety and durability of the equipment.

[0035] Example 2, refer to Figure 1 - Figure 8 This is the second embodiment of the present invention, which differs from the first embodiment in that: the shrinking assembly 21 includes a support member 211 fixedly installed on the inner wall of the charging pile 1, which is used to connect the charging pile 1 and support the shrinking assembly 21 as a whole; a mounting groove 212 fixedly installed on the outer wall of the support member 211, which is used to be fixedly connected to the spiral spring 213; a half gear 218 fixedly installed on the outer wall of the support member 211, which cooperates with the buckle 217 on the blocking ring 216 to achieve rotational limitation; and a rotating column 215 fixedly installed at the other end of the mounting groove 212, which is rotatably connected to the support member 211 and is used to wind up and store the cable 412.

[0036] Compared to Embodiment 1, a further improvement is that: a top block 218-1 is fixedly installed on the half gear 218 for adjusting the limiting state of the buckle 217; a locking plate 214 is fixedly installed on the inner wall of the rotating column 215, which is fixedly connected to the worm spring 213, so as to realize the connection between the worm spring 213 and the rotating column 215, and also to allow the rotating column 215 to rotate freely.

[0037] Furthermore, a blocking ring 216 is fixedly installed on the outer wall of the support member 211 to cooperate with the rotation of the rotating column 215; a buckle 217 is rotatably installed on the blocking ring 216, which is slidably connected and engaged with the half gear 218 to limit the rotation of the blocking ring 216.

[0038] Furthermore, a cable guide ring 219 is fixedly installed on the outer wall of the rotating column 215. The cable guide ring 219 is rotatably connected to the blocking ring 216 and is used to limit and guide the cable 412.

[0039] Furthermore, the electric gun assembly 41 includes an output end 411 fixedly mounted on the charging pile 1 for outputting current; a cable 412 fixedly mounted on the output end 411 for transmitting current; an electric gun 413 fixedly mounted on the other end of the cable 412; and a mounting plate 414 slidably mounted on the electric gun 413, which is fixedly connected to the charging pile 1; meanwhile, the cable 412 is slidably connected to both the retraction assembly 21 and the guide assembly 31 for transmitting current to the vehicle to achieve normal charging.

[0040] During use, the owner first unlocks the charging station 1 by scanning the code, causing the closing part 42 to move upward. Then, the owner takes out the electric gun 413 and pulls it outward. The movement of the cable 412 causes the rotating column 215 to rotate, which in turn compresses the internal spiral spring 213. The blocking ring 216 rotates synchronously, and the buckle 217 on its outer wall moves along the half gear 218 to limit the blocking ring 216 and the rotating column 215, ensuring that the cable 412 will not retract when pulled. Then, charging can begin.

[0041] After charging is complete, the owner pulls the cable 412 again, causing the rotating column 215 and the blocking ring 216 to rotate. The buckle 217 on the blocking ring 216 moves along the outer wall of the half gear 218 to the top block 218-1, changing the angle and releasing the engagement limit with the half gear 218. After the blocking ring 216 and the rotating column 215 are no longer limited, the locking plate 214 inside the rotating column 215 moves in the opposite direction under the action of the worm spring 213, causing the rotating column 215 to rotate in the opposite direction, thereby winding and retrieving the cable 412. After the cable is retracted, the owner inserts the electric gun 413 back into the mounting plate 414 to complete the entire charging process. This eliminates the need for manual cable handling, avoids aging problems caused by long-term exposure of the charging pile cable to sun and rain, and dust and water intrusion. It also prevents the safety hazards of leakage and short circuit caused by the cable being crushed or scratched when placed on the ground, and prevents the cable from getting tangled, pulled, or knotted.

[0042] The remaining structure is the same as that in Example 1.

[0043] Example 3, referring to Figure 1 - Figure 11This is the third embodiment of the present invention, which differs from the second embodiment in that: the guide assembly 31 includes a driving gear 311, a synchronous toothed belt 312, and a driven gear 313. The driving gear 311 is fixedly installed on the outer wall of the blocking ring 216 and is used to drive the synchronous toothed belt 312 to rotate. The synchronous toothed belt 312 is meshed on the driving gear 311. The driven gear 313 is meshed on the other end of the synchronous toothed belt 312. The driving gear 311 is rotatably connected to the support member 211 and can drive the driven gear 313 to rotate through the synchronous toothed belt 312.

[0044] Compared to Embodiment 2, this embodiment further includes a reciprocating screw 314 fixedly installed inside the driven gear 313, and the reciprocating screw 314 is rotatably connected to the charging pile 1. When the driven gear 313 rotates, it can drive the reciprocating screw 314 to rotate synchronously.

[0045] Furthermore, a movable component 316 is slidably mounted on the outer wall of the reciprocating screw 314. The movable component 316 can reciprocate in coordination with the rotation of the reciprocating screw 314. A limiting component 317 is fixedly mounted on the movable component 316 for guiding the movement of the cable 412. A conveying roller 318 is rotatably mounted on the inner wall of the limiting component 317 for correcting and conveying the cable 412. A guide plate 319 is also fixedly mounted on the inner wall of the limiting component 317 for guiding the cable 412. A limiting ring 315 is fixedly mounted on the outer wall of the reciprocating screw 314 to cooperate with the reciprocating movement of the movable component 316 on the reciprocating screw 314.

[0046] During use, when the electric gun 413 is pulled to charge, the pulling of the electric gun 413 will cause the retraction component 21 to rotate, and the drive gear 311 will rotate synchronously with the blocking ring 216. The rotation of the drive gear 311 will drive the synchronous toothed belt 312 and the driven gear 313 to rotate synchronously, and the driven gear 313 will then drive the reciprocating screw 314 to rotate inside the charging pile 1. The moving part 316 will move back and forth along the outer wall of the reciprocating screw 314, and the limiting part 317 will move synchronously with the moving part 316. The guide plate 319 inside the limiting part 317 will guide the cable 412 that passes through, and the conveying roller 318 will cooperate with the guide plate 319 to synchronously correct the cable 412, thereby improving the stability of the cable 412 when it moves and unfolds.

[0047] After charging is complete, the owner can pull the cable 412 again to release the limit of the retraction component 21, causing the retraction component 21 to move in the opposite direction. The drive gear 311 then drives the synchronous toothed belt 312 and the driven gear 313 to rotate in the opposite direction. The moving part 316 on the reciprocating screw 314 begins to move back to its original position, cooperating with the rotating column 215 to complete the winding operation of the cable 412. Through the cooperation of the conveying roller 318 inside the limit component 317 and the guide plate 319, the cable 412 can be prevented from knotting or overlapping during winding, and the cable can be prevented from dragging and wearing on the ground. After charging is completed, the cable is automatically retracted and returned to its original position without manual handling, and the charging pile cable can also be prevented from aging due to long-term exposure to sun and rain and the intrusion of dust and water.

[0048] The remaining structure is the same as that in Example 2.
