[0015] The present invention provides a charging pile with a self-winding function, having the following beneficial effects: (1) In this invention, when the charging cable needs to be wound up, the motor starts to wind up the charging cable. At the same time, the motor starts to drive the ratchet to rotate. The limiting rod contacts the ratchet to limit the reverse rotation of the ratchet, preventing the charging cable from being damaged due to excessive external tension when the charging cable is wound up, increasing the use cost. When the charging cable is wound up and charging is needed again, press the start button. The T-shaped rod squeezes the limiting rod downward, and the limiting rod no longer limits the ratchet. At the same time, the charging cable can be pulled out to charge the car. When the charging cable is wound up again, the ratchet rotates to squeeze the block. The block moves upward under the squeezing force. At the same time, the limiting rod is reset by the elastic force of the first spring to limit the ratchet, improving the winding efficiency of the charging pile body and the applicability of the charging pile body.

[0016] (2) In this invention, the reciprocating thread groove drives the first ring to move up and down, so that the charging cable can be evenly wound around the circumferential surface of the winding wheel, reducing the wear of the charging cable, preventing the charging cable from being wound together and knotted during winding, affecting the use of the charging pile body. At the same time, when the charging cable is wound up, the collar squeezes the sliding rod, so that the long rod squeezes the switch to cut off the power, preventing over-winding, resulting in the charging cable breaking, affecting the use of the charging pile body and increasing the cost.

[0017] (3) In this invention, when the charging cable is being wound up, the scraping plate cleans the charging cable to prevent dirt from adhering to the surface of the charging cable, which may form a conductive path in a humid environment, increasing the risk of electric leakage. At the same time, it prevents the dirt from corroding the surface of the charging cable and affecting the use of the charging pile body. Meanwhile, the pry bar drives the scraping rod to move, so that when the charging cable is being wound up, the surface of the charging cable is cleaned. When the charging cable is being pulled outwards, the scraping rod moves upwards and disengages from the charging cable, improving the convenience of the charging pile body.

Among them, the limiting device includes a ratchet wheel 61, a first cylindrical rod 62, a second cylindrical rod 63, a fixing plate 64, a limiting rod 65, a start button 66, a T-shaped rod 67 and a support rod 68. The ratchet wheel 61 is fixedly installed on the circumferential surface of the transmission shaft 3. The first cylindrical rod 62 is fixedly installed at the bottom of the inner wall of the charging pile body 1. The second cylindrical rod 63 is fixedly installed at the bottom of the inner wall of the charging pile body 1. The fixing plate 64 is fixedly installed on the circumferential surface of the first cylindrical rod 62. The limiting rod 65 is rotatably installed on the circumferential surface of the first cylindrical rod 62. The start button 66 slidably penetrates through the inner and outer walls of the charging pile body 1. The support rod 68 is fixedly installed at the bottom of the inner wall of the charging pile body 1. The T-shaped rod 67 is slidably installed on the side of the support rod 68 close to the limiting rod 65. By limiting the ratchet wheel 61, it is possible to prevent the charging cable 5 from being subjected to an external pulling force during winding, resulting in damage to the charging cable 5 and the equipment, reducing work efficiency, increasing costs, and at the same time, the limit on the ratchet wheel 61 can be released through the start button 66 and the T-shaped rod 67, enabling the charging cable 5 to be extended outward, improving the applicability of the charging pile body 1.

[0022] The limiting device further includes a connecting rod 69, a first elastic telescopic rod 610 and a clamping block 611. The connecting rod 69 is fixedly installed on the side of the T-shaped rod 67 close to the transmission shaft 3. The first elastic telescopic rod 610 is fixedly installed on the side of the connecting rod 69 close to the transmission shaft 3. The clamping block 611 is fixedly connected to the output end of the first elastic telescopic rod 610. When it is necessary to wind the charging cable 5 again, the clamping block 611 moves upward to release the limit on the limiting rod 65, enabling the limiting rod 65 to limit the ratchet wheel 61 again, improving the convenience of the charging pile body 1.

[0023] A first spring is provided between the second cylindrical rod 63 and the limiting rod 65. The side of the T-shaped rod 67 close to the limiting rod 65 is an inclined surface. The limiting rod 65 contacts the ratchet wheel 61, which facilitates the reset of the limiting rod 65 and facilitates the T-shaped rod 67 to squeeze the limiting rod 65.

[0024] During the operation of this embodiment: When it is necessary to wind up the charging cable 5, the motor 2 is started. The start of the motor 2 drives the transmission shaft 3 to rotate. The rotation of the transmission shaft 3 drives the winding wheel 4 to rotate, winding up the charging cable 5. The rotation of the transmission shaft 3 drives the ratchet wheel 61 to rotate. The limiting rod 65 contacts the ratchet wheel 61 and limits the reverse rotation of the ratchet wheel 61, preventing the charging cable 5 from being damaged by external tensile force during winding, which may damage the charging cable 5 and the device, affect the use of the charging pile body 1, increase the cost. When it is necessary to use the charging pile body 1 again, manually press the start button 66. The start button 66 moves towards the transmission shaft 3 under pressure. The start button 66 moves towards the transmission shaft 3 and contacts and presses the T-shaped rod 67. The T-shaped rod 67 moves downward under the extrusion force. The downward movement of the T-shaped rod 67 drives the connecting rod 69 to move downward. The downward movement of the connecting rod 69 drives the first elastic telescopic rod 610 to move downward. The downward movement of the first elastic telescopic rod 610 drives the block 611 to move downward. The block 611 moves downward and contacts the ratchet wheel 61. At the same time, the T-shaped rod 67 moves downward and contacts and presses the limiting rod 65. The limiting rod 65 moves away from the ratchet wheel 61 under the extrusion force, thus releasing the limit on the ratchet wheel 61. After the ratchet wheel 61 is released from the limit, it can rotate in the reverse direction. The reverse rotation of the ratchet wheel 61 allows the charging cable 5 to be pulled outwards to charge the vehicle. At the same time, when winding up the charging cable 5 again, the transmission shaft 3 drives the ratchet wheel 61 to rotate. The ratchet wheel 61 rotates and contacts and presses the block 611. The block 611 moves upward under the extrusion force. The upward movement of the block 611 drives the connecting rod 69 to move upward. The upward movement of the connecting rod 69 drives the T-shaped rod 67 to move upward. The upward movement of the T-shaped rod 67 releases the limit on the limiting rod 65. After the limiting rod 65 is released from the limit, it is reset by the elastic force of the first spring to limit the ratchet wheel 61, improving the winding efficiency of the charging pile body 1 and at the same time improving the applicability of the charging pile body 1.

When the charging cable 5 is pulled out, the scraper 810 is separated from the contact with the charging cable 5 by the elastic force of the No. 3 elastic telescopic rod 89, thereby improving the convenience of the charging pile body 1.

[0030] The circumferential surface of the rotating shaft 72 is provided with a one-way thread groove. The second ring 81 is threadedly connected to the rotating shaft 72. The pry bar 86 does not contact the third ring 87. The side of the U-shaped plate 84 close to the pry bar 86 is an inclined surface, which facilitates the up and down movement of the second ring 81 and facilitates the extrusion of the pry bar 86.

[0031] When this embodiment works: When the charging cable 5 is wound up, the transmission shaft 3 rotates to drive the first gear 71 to rotate. The first gear 71 rotates to drive the second gear 73 to rotate. The second gear 73 rotates to drive the rotating shaft 72 to rotate. The rotating shaft 72 rotates to drive the first ring 74 to move up and down through the reciprocating thread groove. The up and down movement of the first ring 74 drives the up and down movement of the charging cable 5, so that the charging cable 5 can be evenly wound around the circumferential surface of the winding wheel 4, reducing the wear of the charging cable 5 and avoiding knotting and stretching of the charging cable 5. At the same time, when the charging cable 5 is almost fully wound up, the collar 77 contacts and presses the sliding plate 76.

The switch 710 cuts off the power supply to the motor 2 under the pressing force to prevent over-winding, resulting in the breakage and damage of the charging cable 5, affecting the use of the charging pile body 1 and reducing the working efficiency of the charging pile body 1.

[0032] When the charging cable 5 is wound up, the rotating shaft 72 rotates to drive the second ring 81 to move upward through the one-way thread groove. The upward movement of the second ring 81 drives the upward movement of the short rod 811. The upward movement of the short rod 811 drives the upward movement of the first L-shaped rod 82. The upward movement of the first L-shaped rod 82 drives the upward movement of the pull rod 83.

The movement of the U-shaped plate 84 contacts the pry bar 86 and extrudes the pry bar 86. The pry bar 86 is extruded to make the scraping plates 810 move towards each other to clean the surface of the charging cable 5, preventing dirt from adhering to the surface of the charging cable 5, which may form a conductive path in a humid environment and increase the risk of electric leakage. At the same time, it prevents the dirt from corroding the surface of the charging cable 5, affecting the use of the charging pile body 1. At the same time, when the charging cable 5 is pulled out for charging, the rotating shaft 72 rotates in the reverse direction to drive the second ring 81 to move downward through the one-way thread groove. The downward movement of the second ring 81 drives the downward movement of the short rod 811. The downward movement of the short rod 811 drives the downward movement of the first L-shaped rod 82. The downward movement of the first L-shaped rod 82 drives the downward movement of the pull rod 83. The downward movement of the pull rod 83 pulls the U-shaped plate 84 to move away from the pry bar 86. The U-shaped plate 84 moves away from the pry bar 86 and disengages from the contact with the pry bar 86. At the same time, the elastic force of the third elastic telescopic rod 89 makes the scraping plates 810 move away from each other and disengage from the contact with the charging cable 5, improving the convenience of the charging pile body 1.
