Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile with protective functions. Background Technology

[0002] Charging piles, also known as electric vehicle charging stations or electric vehicle power supply equipment, are devices that provide electrical energy to electric vehicles, enabling them to store enough electricity to support their operation. The input end of a charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. To prevent the charging cable from being scattered around the charging pile after use and to facilitate subsequent use by other users, an automatic cable retraction mechanism is usually installed to retrieve the charging cable.

[0003] A search revealed Chinese Patent Publication No. CN214028246U, which discloses an automatic retractable charging pile, comprising: a base; a pile body disposed at the top of the base; a lifting mechanism disposed at the bottom of the inner cavity of the pile body and fixedly connected to the left side of the inner wall of the pile body; a charging device disposed at the top of the lifting mechanism; a warning light disposed at the top of the pile body; a display screen embedded in the top right side of the pile body and electrically connected to the charging device; and a pulley that rotates in the front-back direction via a pin. The automatic retractable charging pile, connected to the bottom right side of the pile body, solves the problem that charging cables easily detach after charging and scatter into parking spaces and roads, easily being run over and damaged by passing cars, causing economic losses, as well as the situation where the charging pile is damaged due to a collision between a car and the charging pile. In this utility model, when retracting or extending the charging cable, it is also necessary to push the charging equipment to lift and lower. However, the movement range of the charging equipment inside the charging pile is limited, which limits the extension length of the charging cable. In summary, this application proposes a charging pile with protective function to effectively protect the charging cable during retraction. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This embodiment of a charging pile with protective function includes a charging pile body 1, a rain shelter 2 fixed on the upper surface of the charging pile body 1, a placement cavity 3 opened at the left end of the front of the charging pile body 1, a cable retraction protection mechanism 4 for automatic cable retraction is provided at the right end of the bottom wall of the placement cavity 3, a slot is opened at the right end of the front of the charging pile body 1, a charging gun 5 is provided in the inner cavity of the slot, and a rainproof mechanism 6 for preventing rainwater from entering the slot is provided on the front of the charging pile body 1 and above the slot.

[0023] The lower surface of the charging pile body 1 is fixed with a waterproof platform. The length and width of the inner cavity of the rain shelter 2 are both greater than the length and width of the charging pile body 1. The left side of the placement cavity 3 is hinged to a repair door through a hinge seat. The inner bottom wall of the placement cavity 3 and the rear side of the turntable 405 are equipped with a charging device. One end of the charging device is connected to the charging cable, and the other end of the charging cable is connected to the charging gun 5.

[0024] Please see Figures 2 to 3To automatically retract the charging cable into the charging pile body 1, the cable retraction protection mechanism 4 in this embodiment includes a protective box 401 fixed to the right end of the bottom wall of the placement cavity 3. A drive motor 402 is fixed to the inner bottom wall of the protective box 401. A rotating rod 403 is rotatably connected to the middle of the bottom wall of the placement cavity 3 via a bearing. Rotating gears 404 are fixed to the outer surface of the rotating rod 403 and the outer surface of the output shaft of the drive motor 402. The two rotating gears 404 are meshed together. The start of the drive motor 402 causes the rotating gear 404 fixed to its output shaft surface to drive the other rotating gear 404 to rotate. The rotation of the two rotating gears 404 can drive the rotating rod 403 to rotate. A turntable is fixed to the upper surface of the rotating rod 403. 405. Both ends of the upper surface of the turntable 405 are fixed with take-up rods 406. A through hole is opened between the side of the placement cavity 3 and the opposite side of the slot. Support frames 407 are fixed at the upper and lower ends of the opposite side of the front and rear side walls of the through hole. A guide pulley 408 is rotatably connected between the opposite side of the front and rear side walls of the inner cavity of the support frame 407 through a bearing. The rotation of the rotating rod 403 causes the turntable 405 and the two take-up rods 406 to rotate. Then, under the rotation of the two take-up rods 406, the charging cable can be extended with the charging gun 5 under the guidance of the two guide pulleys 408 until one end of the charging gun 5 is inserted into the charging port of the car that needs to be charged. The charging cable control button can be pressed again to stop the drive motor 402 from rotating.

[0025] Among them, a semi-annular plate is fixed to the rear end of the opposite side of the left and right side walls of the inner cavity of the placement cavity 3. An annular groove is opened in the middle of the outer surface of the turntable 405. The turntable 405 makes horizontal circular motion in the inner cavity of the semi-annular plate to limit the rotation of the turntable 405 so that it can rotate horizontally.

[0026] Understandably, the cable retraction protection mechanism 4 allows the user to retract the charging cable through the slot onto the outer surface of the two cable retraction rods 406 by pressing the charging cable control button on the surface of the charging gun 5 after use, thus enabling the charging cable to be wound up again. This makes it more convenient to use and is suitable for retracting longer charging cables.

[0027] Please see Figure 4To prevent water from entering and damaging the charging gun 5, the rainproof mechanism 6 in this embodiment includes a connecting frame 601 fixed to the front of the charging pile body 1 and located above the slot. A rainproof baffle 602 is provided on the front side of the slot. The upper surface of the rainproof baffle 602 is rotatably connected to the opposite side of the left and right side walls of the inner cavity of the connecting frame 601 via bearings. A limiting plate 603 is fixed to the lower surface of the rainproof baffle 602. Both the left and right ends of the inner cavity of the limiting plate 603 are provided with compression plates 604. Compression springs 605 are fixed to the upper and lower ends of the opposite side of the two compression plates 604. The compression springs 605 at the left and right ends are opposite to each other. Movable plates 606 are fixed on one side. Pressing the two movable plates 606 causes the compression springs 605 at the upper and lower ends to be compressed, which in turn causes the movable plates 606 to move closer to the pressing plate 604. Limiting blocks 607 are fixed on the opposite sides of the two movable plates 606. The limiting plate 603 is lifted upward to move out of the inner cavity of the limiting groove and the two movable plates 606 are released. The rotation of the limiting plate 603 drives the rainproof baffle 602 to rotate. When the rainproof baffle 602 rotates to a state perpendicular to the charging pile body 1, the charging gun 5 can be pulled out from the slot.

[0028] In this embodiment, the length and width of the inner cavity of the rainproof baffle 602 are both greater than the length and width of the slot. A soft pad is fixed in the inner cavity of the slot. Guide holes are provided at both ends of the front of the limiting plate 603. The front of the movable plate 606 passes through the guide hole and extends to the front side of the guide hole, making it convenient for the user to move the two movable plates 606 relative to each other, thereby squeezing the compression spring 605. A slot is provided on the opposite side of the left and right side walls of the inner cavity of the limiting slot. The size of the limiting block 607 is adapted to the size of the slot cavity. The cross-sectional shape of the limiting plate 603 is L-shaped. The movement of the movable plate 606 causes the limiting block 607 to move out of the slot cavity into the inner cavity of the limiting plate 603, thereby releasing the limiting plate 603. Then the limiting plate 603 is lifted upwards to move out of the inner cavity of the limiting slot.

[0029] The upper and lower sides of the inner top and bottom walls of the limiting plate 603 are provided with sliding grooves. The upper and lower sides of the extrusion plate 604 are fixed with sliders. The sliders move horizontally in the inner cavity of the sliding groove. The front of the charging pile body 1 and the rear side of the limiting plate 603 are provided with a limiting groove. The size of the inner cavity of the limiting groove is adapted to the size of the limiting plate 603.

[0030] Understandably, the rainproof baffle 602 can protect the inner cavity of the slot and the charging gun 5 in rainy weather, preventing water from entering the charging gun 5 and causing damage, thus protecting the service life of the charging gun 5. It can also limit the movement of the rainproof baffle 602, thereby improving its protective capability.

[0031] All electrical components mentioned in this document are electrically connected to the main controller and power supply, and all electrical components mentioned in this document are conventional and known devices. This application will not elaborate further. The main controller can be a conventional and known device such as a computer that performs control. The control circuit of the main controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this application is mainly used to protect mechanical devices, so this application will not explain the control method and circuit connection in detail.

[0032] The working principle of the above embodiments is as follows:

[0033] (1) When charging the charging pile body 1, first open the rainproof baffle 602 and squeeze the two movable plates 606 on the left and right. The movement of the movable plate 606 causes the compression springs 605 at the upper and lower ends to be squeezed, which in turn causes the movable plate 606 to move closer to the squeezing plate 604. The movement of the movable plate 606 drives the limiting block 607 to move out of the inner cavity of the slot to the inner cavity of the limiting plate 603, thereby releasing the limiting plate 603. Then lift the limiting plate 603 upward so that it moves out of the inner cavity of the limiting slot and release the two movable plates 606. The rotation of the limiting plate 603 drives the rainproof baffle 602 to rotate. Then, when the rainproof baffle 602 rotates to a state perpendicular to the charging pile body 1, the charging gun 5 can be pulled out from the slot.

[0034] (2) Pressing the charging cable control button on the charging gun 5 at this time will start the drive motor 402. The start of the drive motor 402 will cause the rotating gear 404 fixed on its output shaft surface to drive the rotation of another rotating gear 404. The rotation of the two rotating gears 404 will drive the rotating rod 403 to rotate. The rotation of the rotating rod 403 will cause the turntable 405 and the two take-up rods 406 to rotate. Then, under the rotation of the two take-up rods 406, the charging cable can be extended with the charging gun 5 under the guidance of the two guide pulleys 408 until one end of the charging gun 5 is inserted into the charging port of the car that needs to be charged. Press the charging cable control button again to stop the drive motor 402 from rotating. After charging, the charging cable can be retracted to the outer surface of the two take-up rods 406 by pressing the charging cable control button.
