Description

Technical Field

[0001] This invention relates to the field of charging equipment technology, specifically a new energy charging pile with an automatic cable winding and anti-crushing structure. Background Technology

[0002] New energy charging piles are dedicated charging infrastructures that provide power replenishment for new energy electric vehicles. They can be divided into various types such as AC charging piles and DC charging piles, and are widely deployed in scenarios such as civilian garages, public parking lots, highway service areas, and dedicated charging stations. They have core functions such as power conversion, charging management and control, and safety protection. They are an important part of the supporting system of the new energy vehicle industry. With the continuous increase in the number of new energy vehicles, the frequency of use of charging piles is constantly increasing, and the application scenarios are becoming increasingly complex. The industry has put forward higher standards for their cable management capabilities, usage safety, and long-term durability.

[0003] There is still room for improvement in the cable management and guidance of existing new energy charging piles. During the cable exit and rewinding process, the cables are prone to disordered arrangement. Long-term repeated use can easily lead to problems such as cable knotting, surface wear, and misalignment. In some usage scenarios, the cables are prone to drooping and being laid on the ground, posing a potential risk of being run over by passing vehicles. To a certain extent, this restricts the safety performance and overall service life of the charging piles and makes it difficult to fully adapt to the long-term stable operation requirements in high-frequency and complex environments. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing new energy charging piles in terms of cable management and guidance. These shortcomings include the tendency for cables to become disorganized during the cable routing and winding process, leading to problems such as cable tangling, surface wear, and misalignment after prolonged use. Furthermore, in some scenarios, cables may droop and fall to the ground, posing a potential risk of being run over by passing vehicles. These issues restrict the safety performance and overall lifespan of charging piles, making it difficult to fully meet the long-term stable operation requirements in high-frequency and complex environments. Therefore, this invention provides a new energy charging pile with an automatic cable winding and anti-crushing structure.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a new energy charging pile with an automatic cable winding and anti-crushing structure, comprising: a charging pile body, a winding component fixedly connected to the side end of the charging pile body, a cable electrically connected to the side end of the charging pile body, one end of the cable passing through the winding component and electrically connected to a charging gun, a driving component provided on the side end of the winding component, and a limiting component provided on the side end of the driving component;

[0006] The winding component includes a fixed cylinder fixedly connected to the side end of the charging pile body, a winding cylinder rotatably connected to the end of the fixed cylinder away from the charging pile body, a winding box fixedly connected to the outer circular surface of the winding cylinder, a guide plate fixedly connected to the inner wall of the winding box, and a limit groove provided on the guide plate.

[0007] The driving component includes a housing fixedly connected to the side end of the take-up box. The take-up drum passes through the take-up box at one end facing the housing and is fixedly connected to a rotating shaft. The rotating shaft passes through the housing. A connecting block one is fixedly connected to the outer circular surface of the housing. A spiral spring is fixedly connected to the end of the connecting block one away from the rotating shaft. A connecting block two is fixedly connected to the outermost end of the spiral spring. One end of the connecting block two is fixedly connected to the inner wall of the side end of the housing.

[0008] The limiting component includes an outer box fixedly connected to the side end of the outer shell, a synchronous shaft fixedly connected to one end of the rotating shaft facing the outer box, the synchronous shaft passing through the outer box and rotatably connected to the outer box, a ratchet fixedly connected to the outer circular surface of the synchronous shaft, an installation rod fixedly connected inside the outer box, and an abutment rod rotatably connected to the outer circular surface of the installation rod.

[0009] As a further embodiment of the present invention: the guide plate is provided in ten sets, evenly distributed in five columns around the center of the winding box, with two sets of guide plates in each column symmetrically distributed on both sides inside the winding box, and multiple sets of limiting grooves are provided on each set of guide plates. The limiting grooves are provided on the corresponding surfaces of every two sets of symmetrically distributed guide plates, and the number, size and position of the limiting grooves on the two sets of symmetrically distributed guide plates are the same. The limiting grooves on the five columns of guide plates are distributed in a threaded manner.

[0010] As a further embodiment of the present invention: the fixed cylinder is connected to the winding cylinder, the outer circular surface of the winding cylinder is provided with a through hole, and the top of the winding box is provided with a through groove for wire exit.

[0011] As a further embodiment of the present invention: the cable passes through the bottom end of the fixed cylinder, extends into the winding box through the connecting hole, and is spirally wound around the outer surface of the winding cylinder through the limiting groove on the guide plate, and finally passes through the cable exit groove.

[0012] As a further embodiment of the present invention: a support plate is fixedly connected to the top of the winding box, and a baffle is fixedly connected to the top of the support plate. The baffle is herringbone shaped and fully covers the cable outlet groove.

[0013] As a further aspect of the present invention: the cross-section of the outer shell is U-shaped, and the opening of the U-shaped outer shell faces the winding box.

[0014] As a further embodiment of the present invention: the top of the outer box is provided with a clearance hole, and the top of the abutment rod is fixedly connected to a pull rod, wherein the diameter of the clearance hole is larger than the diameter of the pull rod.

[0015] As a further embodiment of the present invention: after the top of the pull rod passes through the clearance hole, a lifting block is fixedly connected. The lifting block is T-shaped. The abutment rod falls due to gravity and gets stuck between the teeth of the ratchet, so that the ratchet can only rotate in one direction and cannot rotate in the opposite direction. By lifting the lifting block, the abutment rod is driven to rotate around the mounting rod until the abutment rod leaves the rotation range of the ratchet, thus releasing the restriction of the abutment rod on the ratchet.

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

[0017] 1. In this invention, the cable is neatly stored and guided and protected throughout the entire process by the winding component. It can maintain the orderly arrangement of the cable during the entire process of cable exit and winding, effectively avoiding cable knots, wear and misalignment. At the same time, the top protective structure blocks the intrusion of external debris and rainwater, extending the service life of the cable and internal structure. In the stored state, the cable is completely placed inside the shell, eliminating the risk of the cable being run over by a vehicle when it falls to the ground, and significantly improving the safety and durability of the charging pile.

[0018] 2. In this invention, a driving component provides stable elastic power for automatic cable winding, achieving automatic cable winding without the need for an external power supply or additional electric drive device. The overall structure is compact and easy to install and deploy, with uniform and smooth power output, adaptable to the winding needs of cables of different lengths and specifications. The mechanism has a low failure rate and low daily maintenance cost, effectively ensuring the long-term stable operation of the automatic winding function, and is suitable for various installation and use scenarios of new energy charging piles.

[0019] 3. In this invention, a limiting component is used to achieve one-way automatic locking after the cable is pulled out. The cable can be automatically positioned and fixed when the user pulls it to any length. During the charging process, the cable remains taut and will not retract on its own. At the same time, the unlocking operation is simple and quick, which greatly improves the convenience of charging for users. In the locked state, the cable can be prevented from slack and falling to the ground, further enhancing the actual effect of preventing crushing and fully ensuring the safety of charging operations.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0031] Reference Figure 1 In this embodiment of the invention, a new energy charging pile with an automatic cable winding and anti-crushing structure includes: a charging pile body 1, a winding member 4 fixedly connected to the side end of the charging pile body 1, a cable 2 electrically connected to the side end of the charging pile body 1, one end of the cable 2 passing through the winding member 4 and electrically connected to a charging gun 3, a driving member 5 provided on the side end of the winding member 4, and a limiting member 6 provided on the side end of the driving member 5.

[0032] Reference Figures 2 to 5The winding component 4 includes a fixed cylinder 41 fixedly connected to the side end of the charging pile body 1. A winding drum 42 is rotatably connected to the end of the fixed cylinder 41 away from the charging pile body 1, and the fixed cylinder 41 and the winding drum 42 are in communication. A through hole 43 is provided through the outer circular surface of the winding drum 42. A winding box 44 is fixedly connected to the outer circular surface of the winding drum 42. A cable outlet groove 45 is provided through the top of the winding box 44. A guide plate 46 is fixedly connected to the inner wall of the winding box 44. A limiting groove 47 is provided on the guide plate 46. The cable 2 passes through the bottom end of the fixed cylinder 41 and extends into the winding box 44 through the through hole 43. It is spirally wound around the outer circular surface of the winding drum 42 through the limiting groove 47 on the guide plate 46. Finally, the cable exit trough 45 is traversed. Ten sets of guide plates 46 are provided, evenly distributed in five columns around the center of the winding box 44. Two sets of guide plates 46 in each column are symmetrically distributed on both sides inside the winding box 44. Each set of guide plates 46 has multiple sets of limiting grooves 47. The limiting grooves 47 are opened on the corresponding surfaces of every two sets of symmetrically distributed guide plates 46. The number, size and position of the limiting grooves 47 on the two sets of symmetrically distributed guide plates 46 are the same. The limiting grooves 47 on the five columns of guide plates 46 are distributed in a threaded manner. A support plate 48 is fixedly connected to the top of the winding box 44. A baffle 49 is fixedly connected to the top of the support plate 48. The baffle 49 is herringbone shaped and fully covers the cable exit trough 45.

[0033] The above solution is adopted: the winding drum 42 of the winding component 4 works with the winding box 44 to store the cable 2. The guide plate 46 has a threaded distribution of limiting grooves 47 to guide the cable 2 to spiral and wind neatly, avoiding misalignment and stacking of the cable 2 and mutual squeezing and wear during winding and exiting. At the same time, the herringbone baffle 49 fully covers the exit groove 45, which can prevent external debris and rainwater from entering the inside of the winding box 44, protecting the surface and internal rotating structure of the cable 2, and ensuring stable and smooth winding action.

[0034] Reference Figure 6 The driving component 5 includes a housing 51 fixedly connected to the side end of the take-up box 44. The housing 51 has a U-shaped cross section, and the opening of the U-shaped housing 51 faces the take-up box 44. The take-up drum 42 passes through the take-up box 44 at one end facing the housing 51 and is fixedly connected to a rotating shaft 52. The rotating shaft 52 passes through the housing 51. A connecting block 1 53 is fixedly connected to the outer circular surface of the housing 51. A spiral spring 54 is fixedly connected to the end of the connecting block 1 53 away from the rotating shaft 52. A connecting block 2 55 is fixedly connected to the outermost end of the spiral spring 54. One end of the connecting block 2 55 is fixedly connected to the inner wall of the side end of the housing 51.

[0035] The above solution is adopted: the spiral spring 54 of the drive component 5 is linked with the rotating shaft 52 through the connecting block 53. When the cable 2 is pulled out, the spiral spring 54 stores elastic potential energy at the same time. After the external force is removed, the torque can be released to drive the winding drum 42 to rotate, so as to realize the automatic winding of the cable 2. No additional power device is required. The overall structure is compact and small, easy to install and maintain, and the winding power is continuous and stable, which can adapt to the recycling needs of cables 2 of different lengths.

[0036] Reference Figures 7 to 8 The limiting component 6 includes an outer box 61 fixedly connected to the side end of the outer casing 51. A synchronous shaft 62 is fixedly connected to the end of the rotating shaft 52 facing the outer box 61. The synchronous shaft 62 passes through the outer box 61 and is rotatably connected to the outer box 61. A ratchet 63 is fixedly connected to the outer surface of the synchronous shaft 62. An installation rod 64 is fixedly connected inside the outer box 61. An abutment rod 65 is rotatably connected to the outer surface of the installation rod 64. The abutment rod 65 falls due to gravity and engages between the teeth of the ratchet 63, so that the ratchet 63 can only move in one direction. The ratchet can only rotate in one direction and cannot rotate in the other. The top of the outer box 61 has a through hole 66. The top of the abutment rod 65 is fixedly connected to a pull rod 68. The diameter of the through hole 66 is larger than the diameter of the pull rod 68. After the top of the pull rod 68 passes through the through hole 66, a lifting block 69 is fixedly connected. The lifting block 69 is T-shaped. By lifting the lifting block 69, the abutment rod 65 is driven to rotate around the mounting rod 64 until the abutment rod 65 leaves the rotation range of the ratchet 63, thus releasing the restriction of the abutment rod 65 on the ratchet 63.

[0037] The above solution is adopted: the ratchet 63 of the limiting component 6 and the abutment rod 65 cooperate with gravity to achieve one-way rotation locking. After the cable 2 is pulled out to any length, it can be automatically limited to prevent the cable 2 from retracting on its own. No additional fixation is required when charging. Lifting the lifting block 69 can quickly release the lock and complete the winding. The operation is simple and reliable, effectively improving the convenience and safety of charging.

[0038] The working principle of this invention is as follows: In the standby state, the main body of the cable 2 is spirally wound around the outer surface of the winding drum 42 and stored inside the winding box 44. The charging gun 3 is positioned at the corresponding gun position on the side of the charging pile main body 1. The fixing cylinder 41 provides stable rotation support for the winding drum 42 while ensuring that the cable 2 smoothly passes through the winding drum 42 from inside the charging pile main body 1. At this time, the spiral spring 54 is in the initial energy storage state, and the abutment rod 65 in the limiting member 6 falls naturally under the action of gravity. Its end is locked into the tooth gap of the ratchet 63, restricting the ratchet 63 from rotating in the opposite direction. The whole mechanism is in a locked and ready state.

[0039] When the user needs to charge, the user pulls the charging gun 3 outward at a constant speed. The cable 2, under tension, extends outward along the cable outlet 45, causing the winding drum 42 to rotate forward around the fixed drum 41. During the rotation of the winding drum 42, the rotating shaft 52 at its end rotates synchronously. The rotating shaft 52, through the connecting block 53, pulls the inner end of the spiral spring 54 to rotate synchronously, causing the spiral spring 54 to gradually tighten and its elastic potential energy to continuously accumulate. Simultaneously, the synchronous shaft 62 at the end of the rotating shaft 52 drives the ratchet 63 to rotate synchronously in the forward direction. The beveled surface of the tooth 3 continuously lifts the end of the abutment rod 65, causing the abutment rod 65 to swing back and forth slightly around the mounting rod 64. This does not obstruct the forward rotation of the ratchet 63, ensuring that the cable 2 can be pulled out smoothly. During the cable exit process, multiple sets of guide plates 46 inside the winding box 44 continuously guide the cable 2 through the limiting grooves 47. The limiting grooves 47, which are distributed in a threaded manner, guide the cable 2 to leave the winding drum 42 layer by layer in an orderly manner, preventing the cable 2 from moving, knotting, or misaligning and getting stuck in the winding box 44, and maintaining a smooth and stable cable exit action.

[0040] When cable 2 is pulled out to the required length for vehicle charging, the user releases the pull. At this time, the rebound torque of the spiral spring 54 will cause the winding drum 42 to rotate in the opposite direction. The synchronous shaft 62 and ratchet 63 will also rotate in the opposite direction. The abutment rod 65 falls quickly under its own weight, and its end gets into the tooth gap of the ratchet 63 and abuts against the right angle edge of the tooth surface, preventing the ratchet 63 from rotating in the opposite direction. Then, the synchronous shaft 62 and the rotating shaft 52 lock the rotation state of the winding drum 42, so that cable 2 maintains the current pulled-out length and will not retract on its own due to the spring rebound.

[0041] During the charging operation, the cable 2 is kept taut by the ratchet 63, preventing it from slacking, sagging, or lying flat on the ground. This prevents the cable 2 from being run over by vehicles. At the same time, the herringbone baffle 49 at the top of the rewind box 44 completely covers the cable outlet 45, preventing rainwater, dust, and debris from falling into the rewind box 44. This protects the insulation layer of the cable 2 and the internal rotating mechanism from corrosion, extending the service life of the mechanism.

[0042] After charging is complete, the user pulls the charging gun 3 out of the vehicle charging port, holds the end of the cable 2 and pulls it outward slightly to eliminate the clamping force on the tooth surface, and then pulls the lifting block 69 upward. The lifting block 69 drives the pull rod 68 to move upward along the clearance hole 66. The bottom end of the pull rod 68 pulls the abutment rod 65 to rotate upward around the mounting rod 64, so that the end of the abutment rod 65 is completely out of the rotation range of the ratchet 63, and completely releases the reverse locking restriction on the ratchet 63.

[0043] After the lock is released, the spiral spring 54 smoothly releases the stored elastic potential energy, which drives the rotating shaft 52 to rotate in the opposite direction at a uniform speed through the connecting block 53. The rotating shaft 52 synchronously drives the winding drum 42 to rotate in the opposite direction, winding the cable 2 layer by layer to the outer surface of the winding drum 42. During the winding process, the limiting groove 47 of the guide plate 46 continuously guides the cable 2 to arrange it, so that the cable 2 is evenly wound on the surface of the winding drum 42 along the spiral trajectory, avoiding the stacking, misalignment and mutual compression of the cable 2, and ensuring that the winding process is smooth and without jamming.

[0044] As the winding drum 42 continues to rotate, the exposed cable 2 length gradually shortens and is eventually fully retracted into the winding box 44. Finally, the charging gun 3 returns to its parking position at the side of the charging pile body 1, completing the entire automatic winding process. After the cable 2 is fully retracted, external vehicles cannot contact the cable 2 body, eliminating the risk of the cable 2 being crushed from the root. After winding is completed, the user releases the lifting block 69, and the abutment rod 65 naturally falls back around the mounting rod 64 under the action of gravity, re-engaging into the tooth gap of the ratchet 63, restoring the one-way locking state, and preparing for the next charging use.

[0045] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
