After one charge is completed, the power cord 5 can be automatically reeled in by the reeling mechanism, and the dirt and impurities on the surface of the power cord 5 can be cleaned by the cleaning mechanism, thereby improving the service life of the power cord 5. Through the action of the charging pile in the present invention, the power cord 5 is placed inside the cavity 3, which can avoid the problem that the power cord 5 in the prior art is scattered on the ground and exposed to direct sunlight, resulting in a reduction in its service life.

When the winding wheel 4 rotates following the pulling of the power cord 5, the winding wheel 4 will simultaneously drive the limiting tooth plate 11 to rotate. When the limiting tooth plate 11 rotates, it will squeeze the limiting bevel gear 10 on one side and make the limiting bevel gear 10 rotate. After the power cord 5 is pulled to a suitable position, the limiting bevel gear 10 again limits the limiting tooth plate 11, so that the winding wheel 4 can be fixed, ensuring that the charging head 6 is tightly stuck in the charging position of the vehicle, avoiding the problem of reversal and recovery of the winding wheel 4 when the power cord 5 is subjected to external tension, which is beneficial to the normal charging of the vehicle.

[0028] The driving unit comprises: a round rod 18, which is slidably arranged inside the cavity 3, and a spring is arranged at the contact position between the round rod 18 and the inner wall of the cavity 3; a spiral groove 19, which is opened on the outer circumferential surface of the round rod 18; a limit head 20, which is installed on the groove wall of the annular groove 17, and the shape of the limit head 20 is adapted to the shape of the spiral groove 19; an inclined plate 21, which is slidably arranged inside the cavity 3, and the outer wall of the power cord 5 is connected to the side wall of the inclined plate 21 through a soft rope, and the inclined surface of the inclined plate 21 is in contact with the end of the round rod 18; During operation, when the power cord 5 is pulled out, the power cord 5 will simultaneously pull the inclined plate 21 upward, and then the inclined surface of the inclined plate 21 will squeeze the end of the round rod 18, so that the round rod 18 moves to the side close to the annular groove 17. At this time, the round rod 18 moves horizontally and stretches the spring in contact with it; since the outer circumferential surface of the round rod 18 is provided with a spiral groove 19, the limit head 20 is located inside the spiral groove 19, and during the horizontal movement of the round rod 18, under the limitation of the spiral groove 19 on the limit head 20, the limit head 20 can move along the trajectory of the spiral groove 19, that is, the gear integrated with the limit head 20 16 will rotate at a certain angle, so the gear 16 drives the gear ring 15 to rotate, so that the gear ring 15 can drive the cleaning ring 14 to rotate and clean the power cord 5; when the power cord 5 is retracted, that is, when the inclined plate 21 is away from the end of the round rod 18, the round rod 18 can be restored to its initial position under the recovery of the spring on the surface of the round rod 18, that is, the gear 16 and the gear ring 15 will reverse, so that the power cord 5 can be further cleaned, avoiding the problem of too much dirt adhering to the power cord 5, which causes corrosion to the power cord 5 body and reduces the service life under long-term use, which is beneficial to the normal use of the present charging pile.

[0029] The cavity 3 has a limit groove inside which matches the round rod 18, and the round rod 18 is slidably arranged in the limit groove through a limit support rod. The limit groove is provided to facilitate the round rod 18 to move along the inside of the annular groove 17, thereby facilitating its driving the gear 16 to rotate.

[0031] Working principle: when the charging pile is not in use, the power cord 5 is wound around the outer circumference of the winding wheel 4; when the vehicle needs to be charged, the driver first pulls out the charging head 6 from the surface of the display screen seat 2, and then pulls the power cord 5 out from the cavity 3, and then the vehicle can be charged through the charging head 6. After one charge is completed, the power cord 5 can be automatically wound up by the winding mechanism, and the dirt and impurities on the surface of the power cord 5 can be cleaned by the cleaning mechanism to improve the service life of the power cord 5. Through the function of the charging pile in the present invention, the power cord 5 is placed inside the cavity 3, which can avoid the problem that the power cord 5 is scattered on the ground in the prior art and is exposed to direct sunlight, resulting in a reduction in its service life; In the initial state, the limiting bevel gear 10 is located between a pair of ratchet teeth on the surface of the limiting tooth plate 11. When the winding wheel 4 rotates following the pulling of the power cord 5, the winding wheel 4 will simultaneously drive the limiting tooth plate 11 to rotate. When the limiting tooth plate 11 rotates, it will squeeze the limiting bevel gear 10 on one side and make the limiting bevel gear 10 rotate. After the power cord 5 is pulled to a suitable position, the limiting bevel gear 10 limits the limiting tooth plate 11 again, which can fix the winding wheel 4 and ensure that the charging head 6 is tightly stuck in the vehicle charging position to avoid the power cord 5 being subjected to external tension, which will cause The problem of reverse recovery of the winding wheel 4 is conducive to the normal charging of the vehicle; when the vehicle is charged, the control knob on the surface of the display screen seat 2 and the controller are used to control the electric telescopic rod 901 to move, so that the telescopic end of the electric telescopic rod 901 drives the limiting cone tooth 10 away from the limiting tooth plate 11, and then the power cord 5 can be quickly retracted under the elastic force recovery of the torsion spring 7, and the subsequent use is convenient, avoiding the problem of the power cord 5 being scattered on the ground in the prior art, which not only ensures the neatness of the arrangement of the power cord 5, but also improves the service life of the power cord 5; When the power cord 5 is pulled, it will simultaneously drive the gear 16 to rotate through the driving unit, the gear 16 will drive the gear ring 15 to rotate, and the gear ring 15 will drive the cleaning ring 14 to rotate, and then when the power cord 5 is retracted, the cleaning ring 14 will rotate at the same time, and then it can treat different dirt and impurities on the surface of the power cord 5, thereby improving the treatment effect of the power cord 5 and increasing the service life of the power cord 5; when the power cord 5 is pulled out, the power cord 5 will simultaneously pull the inclined plate 21 upward, and then the inclined surface of the inclined plate 21 will squeeze the end of the round rod 18, so that the round rod 18 moves to the side close to the annular groove 17. At this time, the round rod 18 moves horizontally and stretches the spring in contact with it; because the outer circumferential surface of the round rod 18 is provided with a spiral groove 19, the limit head 20 is located inside the spiral groove 19, and the round rod 1 During the horizontal movement, the limit head 20 is limited by the spiral groove 19, so that the limit head 20 can move along the trajectory of the spiral groove 19, that is, the gear 16 installed integrally with the limit head 20 will rotate at a certain angle, so the gear 16 drives the gear ring 15 to rotate, so that the gear ring 15 can drive the cleaning ring 14 to rotate and clean the power cord 5; when the power cord 5 is retracted, that is, when the inclined plate 21 is away from the end of the round rod 18, the round rod 18 can be restored to its initial position under the recovery of the spring on the surface of the round rod 18, that is, the gear 16 and the gear ring 15 will reverse, so that the power cord 5 can be further cleaned to avoid the problem of too much dirt adhering to the power cord 5, which causes corrosion to the power cord 5 body and reduces the service life under long-term use, which is beneficial to the normal use of the charging pile.

[0032] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
