TECHNICAL FIELD
[0001] The present application relates to the technical field of charging piles, in particular to a charging pile. BACKGROUND
[0002] With the gradual increase of electric vehicles, many public areas also install charging piles for electric vehicle charging, for example, a plurality of charging piles are installed in public parking lots, residential parking lots or specially set charging stations.
[0003] At present, the standard charging pile is provided with a charging wire and a charging gun, and the length of the charging wire is 3-4 meters. Since the charging pile does not have the function of automatically winding the wire, the wire is prone to disorder when being retracted and extended, which not only affects the appearance but also seriously entangles the wire, which is not easy to pull out for use again. Long-time pulling of the wire causes the friction resistance to increase, thereby causing the damage of the insulating skin outside the wire and the decrease of the service life of the wire. Since the wire belongs to non-safety voltage, once the insulation is damaged, safety hazards such as insulation abnormality will occur, and if not timely discovered, electric shock and other accidents will occur. SUMMARY

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Please see Figures 1-7 This invention provides a technical solution: a charging pile, comprising: a housing 1, wherein the housing 1 is divided into a first chamber 3 and a second chamber 4 by a partition 2; the first chamber 3 is equipped with a cable retracting device 31 capable of bidirectional telescopic cable retraction; the second chamber 4 is equipped with a first motor 32 capable of driving the cable retracting device 31 to rotate 0-180 degrees; the two telescopic ends of the cable retracting device 31 are equipped with rolling clamping mechanisms 7; one end of the charging cable passes through the two rolling clamping mechanisms 7 and a drive mechanism 51 embedded in the side wall of the housing 1 and is connected to the charging gun; the drive mechanism 51 can clean the outer wall of the charging cable by abrasion; at the same time, a plug-in component 42 capable of vertical sliding and movably plugging into the charging gun is equipped on one side of the housing 1.
[0032] In some embodiments of the present invention, the take-up device 31 includes a rotating shaft 311. One end of the rotating shaft 311 extends through the partition 2 to the second chamber 4 and is connected to the output end of the first motor 32. The other end of the rotating shaft 311 extends into the first chamber 3 and is connected to a rotating column 312 disposed at one end of the rotating shaft 311. Two symmetrical arc-shaped grooves 313 are provided on the side wall of the rotating column 312 near the rotating shaft 311. A rotating ring 314 is sleeved on the end of the rotating shaft 311 near the first chamber 3. Two insert rods 315 are symmetrically disposed on the rotating ring 314, and the two insert rods 315 are respectively inserted into the arc-shaped grooves 313. The rotation of the first motor 32 drives the rotating shaft 311 to rotate, which in turn drives the rotating column 312 and the insert rods 315 to rotate together. The insert rods 315 are inserted into the arc-shaped grooves 313. The connection between the rotating shaft 311 and the rotating column 312 is more stable and compact by using the insert rods 315, which is beneficial to the rotation of the rotating column 312.
[0033] In some embodiments of the present invention, the rotating column 312 is provided with a through hole 3121, and an electric telescopic rod 3122 is symmetrically arranged along the axis of the through hole 3121. The output end of the electric telescopic rod 3122 extends laterally and extends beyond one side of the end of the rotating column 312. A slide rail 3123 is provided on the side wall of the rotating column 312 near the partition 2, and a sliding rod 3124 is provided on the slide rail 3123 to slide with it. By using the electric telescopic rod 3122, the charging cable can be wound up and unwound using the length of the rod, which is beneficial for storing the charging cable in the housing 1 of the charging pile. With the cooperation of the slide rail 3123 and the sliding rod 3124, when the electric telescopic rod 3122 extends outward, it drives the sliding rod 3124 to slide outward as well, thereby making the connection between the rolling clamping mechanism 7 mentioned below and the electric telescopic rod 3122 and the sliding rod 3124 more stable, which is beneficial for winding up the charging cable. For example, the first motor 32 rotates the electric telescopic rod 3122 counterclockwise, thereby using the rolling clamping mechanism 7 of the electric telescopic rod 3122 to pull the wire with the charging gun end into the housing 1, thus retracting the excess wire outside the housing 1 into the housing 1. For example, after the electric telescopic rod 3122 is fully extended, rotating it counterclockwise by 45° can retract one meter of the charging wire outside the housing 1 inward, and rotating it counterclockwise by 90° can retract two meters of the charging wire outside the housing 1 inward. This wire retraction method is simple in structure and easy to operate. The angle can be adjusted as needed to retract the charging wire into the housing 1. Conversely, when charging is needed, the first motor 32 is rotated in the opposite direction to release the charging wire. The operator only needs to pull the wire outward. The structure is compact, the operation is simple, and the practicality is strong.
[0034] In some embodiments of the present invention, the rolling clamping mechanism 7 includes a connecting block 71. The connecting block 71 has an inner groove 72 arranged vertically within it. One side wall of the connecting block 71 is connected to the output end of the electric telescopic rod 3122, and the adjacent side wall of the connecting block 71 is connected to the slide rod 3124. Two symmetrically placed wire clamping rings 73 are provided inside the inner groove 72 of the connecting block 71. A rotating shaft 74 passes through the axis of each wire clamping ring 73, and both ends of the rotating shaft 74 are connected to the side wall of the connecting block 71. By using the two wire clamping rings 73, the charging cable passes between them. The concave surface of the wire clamping ring 73 matches the arc shape of the charging cable, making it easy to pull and reducing friction between them. This allows for convenient clamping of the wire, preventing excessive wear during movement and shortening its service life.
[0035] In some embodiments of the present invention, a first slot 5 is provided outside the first chamber 3 of the housing 1, and the drive mechanism 51 is embedded in the first slot 5. The drive mechanism 51 includes a horizontal plate 511 installed in the first slot 5. A second motor 512 is provided on the horizontal plate 511. The output end of the second motor 512 is connected to a first rotating rod 513. One end of the first rotating rod 513 passes through the horizontal plate 511, and a first gear is sleeved on the bottom end of the first rotating rod 513 located on the horizontal plate 511. 514, both sides of the first gear 514 are meshed with second gears 515, and the shafts of the two second gears 515 are provided with second rotating rods 517. The bottom of the second rotating rods 517 is connected to a sector block 516. The bottom of the sector block 516 is fixedly connected to the inner bottom of the first slot 5. The bottom of the second rotating rods 517 is inserted into the top of the sector block 516. Each of the two second rotating rods 517 is fitted with a sleeve 518. The sleeve 518 is uniformly fitted with brushes that can clean the outside of the charging cable. The rotation of the second motor 512 drives the rotation of the first gear 514, which in turn drives the rotation of the second gears 515 on both sides. This, in turn, causes the sleeves 518 and brushes on the second rotating rod 517 to rotate. The rotation of the brushes, along with the electric telescopic rod 3122 pulling the charging cable into the housing 1, cleans the outside of the charging cable, which is threaded between the two sleeves 518, removing rainwater and dust. This prevents rainwater from being brought into the housing 1 and making cleaning difficult. The fan-shaped block 516 allows the cleaned rainwater and dust to slide quickly off its curved surface and fall to the ground, preventing accumulation.
[0036] In some embodiments of the present invention, a second slot 41 is provided outside the second chamber 4 of the housing 1, and the plug-in assembly 42 is fitted inside the second slot 41. The plug-in assembly 42 includes a support plate 421, a third motor 422 is provided on the support plate 421, the output end of the third motor 422 passes through the support plate 421, and the output end of the third motor 422 is connected to a threaded rod 423. The other end of the threaded rod 423 is connected to the inner bottom of the second slot 41. A slider 424 is mounted on the threaded rod 423, and a socket 427 for placing a charging gun is provided on the slider 424. The internal thread of the slider 424 engages with the external thread of the threaded rod 423. Protrusions 425 are provided on both sides of the slider 424, and a sliding groove 426 is provided on the inner wall of the second slot 41. The protrusions 425 are inserted into the sliding groove 426 and slide in cooperation with the sliding groove 426. The rotation of the third motor 422 drives the rotation of the threaded rod 423. The threaded engagement between the slider 424 and the threaded rod 423 facilitates the movement of the socket 427 up and down within the second slot 41, allowing different people to easily insert the charging gun into the socket 427. Specifically, since charging stations are typically placed outdoors, to prevent accidental operation by children when unattended, a safety feature is implemented. After charging, the charging gun can be inserted into the socket 427, and the third motor 422 can be started to rotate counter-clockwise, moving the slider 424 and the charging gun upwards away from the ground. During use, the third motor 422 can be started to rotate clockwise, moving the slider 424 and the charging gun downwards for easy retrieval.
[0037] In some embodiments of the present invention, the first slot 5 and the second slot 41 are located on the same side wall of the housing 1, and the distance between the first slot 5 and the top of the housing 1 is less than the distance between the first motor 32 and the top of the housing 1. By setting the first slot 5 and the second slot 41 on the same side, the distance can be shortened, reducing the amount of charging cable exposed outside the housing 1 at the bottom of the charging gun head, thus allowing more charging cables to be collected inside the housing 1.
[0038] In some embodiments of the present invention, the two electric telescopic rods 3122 extend in opposite directions, and the length of the two electric telescopic rods 3122 after lateral extension is less than the lateral length of the housing 1. By ensuring that the fully extended length of the electric telescopic rods 3122 is less than the length of the housing 1, it is possible to avoid the inner sidewall of the housing 1 obstructing the electric telescopic rods 3122 during rotation, which would be detrimental to the rotation of the electric telescopic rods 3122.
[0039] In some embodiments of the present invention, the first slot 5 is connected to the first chamber 3. A plurality of vertically distributed heat dissipation holes 9 are provided on one side wall of the housing 1 opposite to the second slot 41. The heat dissipation holes 9 facilitate heat dissipation for the electronic components inside the housing 1.
[0040] The above description is only 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.
