Description

Technical Field

[0001] The utility model relates to the technical field of new energy charging piles, in particular to an automatic retractable device for charging pile cables. Background Art

[0002] A charging pile refers to a charging device that provides energy for electric vehicles. Its function is similar to that of a gas pump in a gas station. It can be fixed on the ground or on a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels. Such convenient service equipment also needs to be as convenient as possible during use. Therefore, the charging cable at the upper end is generally reeled in by an automatic reeling device at the upper end to reduce the user's operation time.

[0003] In view of this, Chinese patent number CN216403455U proposes an automatic cable retracting charging pile. When charging is completed, unplug the plug, and under the elastic action of the first torsion spring, the first winding roller is rotated in the opposite direction to retract the pulled cable, thereby achieving the function of automatic retraction. The operation is simple, and the problem of complex structure and inconvenience for staff to operate is solved. However, the outer skin of the charging cable will be damaged during frequent pulling and pulling. Therefore, after using it for a period of time, it is necessary to remove it and replace the outer skin or replace the entire cable. When the existing automatic cable reeling device reels the cable, it is usually fixed inside the charging pile, making it difficult to disassemble the cable, increasing the operation time and energy of the maintenance workers, and reducing the convenience of using the device.

When the winding shaft 8 is installed, it contacts with the anti-slip pad 6, so that when the winding wheel 3 rotates, the winding shaft 8 will not rotate relative to it.

[0025] The outer walls of the other ends of the two buckles 10 are sleeved with springs 11, and one end of the two springs 11 is fixedly connected to one side of the two first arc-shaped brackets 4 respectively, and one end of the buckle 10 is in an arc shape. When the snap ring 7 is inserted into the slot 9, it directly squeezes the buckle 10 to make it insert into the slot 9, and then under the action of the spring 11, it is inserted into the snap ring 7;

[0026] Furthermore, the cable winding guide mechanism with wiping and drying function includes two protective bases 13 fixed on one side of the charging pile base 1 and one side of the charging pile cover 2, and both ends of the inner walls of the two protective bases 13 are rotatably provided with traction guide wheels 14.

[0027] An electric telescopic rod 15 is fixedly provided on one side of the inner wall of the two protective bases 13, and a cleaning sponge 16 is fixedly provided on the output end of the two electric telescopic rods 15. A through groove 17 is provided on one side of the inner wall of one of the protective bases 13, and a protective net 18 is fixedly provided on the inner wall of the through groove 17. When the two cleaning sponges 16 are pushed to contact the wrapped cables, the normal pulling and retracting of the cables is not affected, and the traction guide wheel 14 not only makes the pulling and retracting of the cables smoother, but also reduces the wear between the cables and the charging pile.

[0028] Furthermore, a motor 12 is fixedly provided at the upper end of one side of the charging pile base 1, and one end of one of the winding wheels 3 is fixedly connected to the output end of the motor 12, connecting rings 19 are fixedly provided on both sides of the outer wall of the charging pile base 1 and both sides of the outer wall of the charging pile cover 2, and two screws are inserted through the inner walls of the four connecting rings 19, and the outer wall of the winding shaft 8 is sleeved with a charging cable 20, and the outer walls of the charging cable 20 are respectively inserted and connected with the inner walls of the two protective bases 13, and the connecting rings 19 at the upper ends of the charging pile base 1 and the charging pile cover 2 can be locked by a locking connection, or they can be connected and fixed by a screw, so that the interior of the cable is in a closed state when it is not replaced and maintained.

[0029] A switch panel is fixedly provided on the outer wall of the charging pile base 1, and the motor 12 and the electric telescopic rod 15 are electrically connected to an external power source through the switch panel.

[0030] Working principle: When using the automatic cable retracting device for charging piles in the present design, it is first necessary to install the reel 8 at the upper end of the device between the two reel wheels 3. When retracting and releasing the charging cable 20, start the motor 12 to rotate one of the reel wheels 3, and drive the reel wheels 3 and the reel shaft 8 at both ends to rotate together through the connection of the reel shaft 8, so that the charging cable 20 can be retracted and released. When the cable is pulled for a long time and its outer skin is worn out or the cable is old, open the upper cover 2 of the charging pile, pull the buckles 10 on one side of the two first arc-shaped brackets 4 to disengage them from the clamping of the clamping ring 7, so that the two second arc-shaped brackets 5 can rotate at the upper end of the first arc-shaped bracket 4, and release the fixation of the two ends of the reel shaft 8, so that the reel shaft 8 and the charging cable 20 can be removed together for replacement. When disassembling, one end of the charging cable 20 needs to be unplugged from the upper end of the charging pile base 1. After replacement, the cable is reeled in by the reel shaft 8, and its two ends are clamped in the two first arc-shaped brackets 4. At the upper end, cover the second arc-shaped bracket 5 so that the clamping ring 7 at its upper end is clamped into the clamping groove 9 and the clamping buckle 10 is squeezed. Under the action of the spring 11, the clamping buckle 10 clamps the clamping ring 7 again, and the charging cable 20 can be retracted and released by rotating the reeling wheel 3 to rotate the reeling shaft 8, thereby improving the convenience of using the device. In the process of using the charging cable 20, when encountering rainy and snowy weather causing a large number of water droplets to adhere to its surface, in the process of retracting the cable through the retracting structure, the cable passes through the inside of the protective base 13 and is pulled by the traction guide wheel 14 therein so that the direction of insertion is consistent and not easy to deviate. The electric telescopic rods 15 in the two protective bases 13 are started so that the two cleaning sponges 16 wrap the two sides of the cable. During the retracting and releasing process, the water droplets and snowflakes on the upper end of the cable are wiped off, so that its surface remains dry to a certain extent, avoiding the accumulation of water inside the charging pile base 1 due to the accumulation of water droplets on the cable surface, causing a short circuit in the equipment, and the wiped and dripped water droplets are discharged through the through groove 17, thereby improving the safety of using the device.
