[0026] The following will further describe the present utility model in conjunction with the Figures 1-5 accompanying drawings.

[0027] In order to solve the problems existing in the background art, the present application proposes the following technical solution: a charging cable retracting and extending device for a charging pile.

[0028] In the specific technical solution, it includes a box body 1 and an anti-twist assembly 4;

[0029] As Figures 1-5 shown, mounting grooves 2 are symmetrically formed on the side walls of the box body 1, and a power-on rod 3 is installed at the central part of the mounting groove 2. The mounting groove 2 can facilitate the installation of the power-on rod 3, and the power-on rod 3 can facilitate the connection with the power-on head 402 and supply power to the power-on head 402; the anti-twist assembly 4 is inserted into the mounting groove 2 and is used to prevent the electric wire from being twisted off. The anti-twist assembly 4 includes two fixing structures. The fixing structures are symmetrically installed in the mounting groove 2 and are clamping plates 401 sleeved outside the power-on rod 3 and a power-on head 402 inserted into the power-on rod 3. The clamping plates 401 can clamp and fix the cable body 405, and the power-on head 402 can transmit the current received from the power-on rod 3 to the cable body 405. The clamping plates 401 are sleeved outside the power-on head 402, and bolts 403 are symmetrically penetrated through the side walls. The bolts 403 can connect the two clamping plates 401. Nuts 404 are threadedly connected to the bolts 403, and the nuts 404 can fix the bolts 403 on the clamping plates 401, enabling the connection between the two clamping plates 401 to be more reliable. A cable body 405 penetrating through the clamping plates 401 is fixedly installed on the power-on head 402. The cable body 405 can supply electric energy to the charging gun 406. A charging gun 406 is fixedly installed at one end of the cable body 405 away from the power-on head 402, and the charging gun 406 can charge the vehicle.

[0030] First, insert the energizing head 402 into the energizing rod 3. Then, clamp two clamping plates 401 outside the energizing rod 3 and the energizing head 402. Stretch the cable body 405, and then clamp the two clamping plates 401 outside the cable body 405. Pass the bolt 403 through the side walls of the two clamping plates 401 in sequence, and then screw the nut 404 onto the bolt 403. The nut 404 is fixed to the bolt 403, and the nut 404 and the bolt 403 can drive the two clamping plates 401 to be fixed. The two clamping plates 401 can be fixedly sleeved outside the energizing rod 3, and the two clamping plates 401 can fix the energizing head 402 inside the energizing rod 3. When the cable body 405 is retracted and released, the clamping plate 401 rotates to drive the cable body 405 wound outside the clamping plate 401 to rotate. A section of the cable body 405 connected to the charging gun 406 can be retracted and released, and a section of the cable body 405 connected to the energizing head 402 is fixed by the clamping plate 401 and rotates with the clamping plate 401. The energizing head 402 rotates with the cable body 405 and the clamping plate 401, which can prevent a section of the cable body 405 connected to the energizing head 402 from being twisted off. At the same time, the energizing head 402 is always in contact with the energizing rod 3, which is convenient for the energizing rod 3 to supply electric energy to the energizing head 402.

[0031] As Figure 1 and Figures 3-5 shown, a power assembly 5 is installed on the side wall of the box body 1. The power assembly 5 is used to drive the anti-twist assembly 4 to rotate. The power assembly 5 includes two power structures. The power structure includes a motor one 501 fixedly installed on the side wall of the box body 1 and a storage box 502. The motor one 501 can drive the gear 503 to rotate. The storage box 502 can conveniently store the cable body 405. A gear 503 located inside the storage box 502 is fixedly installed on the output shaft of the motor one 501. The gear 503 can conveniently drive the turntable 504 to rotate through the tooth groove 7. The storage box 502 is sleeved outside the cable body 405 and a turntable 504 located on one side of the cable body 405 is installed inside. The turntable 504 can drive the clamping plate 401 to rotate through the through hole 6. A through hole 6 sleeved outside the clamping plate 401 is opened at the central part of the turntable 504 and a tooth groove 7 meshing with the gear 503 is opened on the side wall. The through hole 6 can be connected to the clamping plate 401, and the tooth groove 7 can mesh with the gear 503.

[0032] By starting the motor one 501 to drive the gear 503 to rotate, the gear 503 drives the tooth groove 7 to rotate, the tooth groove 7 drives the turntable 504 to rotate, the turntable 504 drives the through hole 6 to rotate, and the through hole 6 drives the clamping plate 401 to rotate. The clamping plate 401 can wind up and release the cable body 405.

[0033] As Figure 4As shown in the figure, a driven shaft 8 and a second motor 9 are fixedly installed in the storage box 502. The driven shaft 8 can limit the cable body 405, and the second motor 9 can drive the driving shaft 10 to rotate. A driving shaft 10 located in the storage box 502 is fixedly installed on the output shaft of the second motor 9. The driving shaft 10 can apply a pulling force to the cable body 405. The cable body 405 is threaded between the driven shaft 8 and the driving shaft 10.

[0034] When the cable body 405 is deflected, the end of the cable body 405 close to the charging gun 406 extends out of the storage box 502. At the same time, the second motor 9 is started to drive the driving shaft 10 to rotate. The driven shaft 8 and the driving shaft 10 squeeze both sides of the cable body 405. When the driving shaft 10 rotates, it applies a downward pulling force to the side wall of the cable body 405. The cable body 405 slides downward and drives the driven shaft 8 to rotate at the same time. The driven shaft 8 and the driving shaft 10 cooperate to stretch the cable body 405 downward, preventing the cable body 405 wound around the clamping plate 401 from accumulating in the storage box 502.

[0035] As Figure 1 shown, a display screen 11 is fixedly installed on the side wall of the box body 1. Charging information can be displayed on the display screen 11.

[0036] As Figure 1 shown, indicator lights 12 are symmetrically installed on both sides of the display screen 11 on the box body 1. The indicator lights 12 can display the charging status.

[0037] As Figure 1 shown, reminder boards 13 are symmetrically installed on the box body 1. The reminder boards 13 can remind the charging ports on the corresponding sides.

[0038] All the standard parts used in the present utility model can be purchased from the market.
