DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0023] See also Figure 1 - Figure 6In the present embodiment, a cable protection device for a charging pile is provided, which is specifically used to protect charging cables in electric vehicle charging stations, and specifically comprises: a storage bin 1, wherein the inner cavity of the storage bin 1 is provided with a winding component 2 for winding the cable in the storage bin 1, wherein the winding component 2 comprises a winding core 21 rotatably arranged in the storage bin 1, wherein the winding core 21 is adapted to be equipped with a driving motor 22 for driving the winding core 21 to rotate, a traction rope 23 is fixed to the side of the winding core 21, an opening 11 is provided at the bottom of the storage bin 1, and a grabbing component 3 for fixing the cable is installed at one end of the traction rope 23.

[0024] Specifically, in this embodiment, when used for the first time, the traction rope 23 is located in the storage bin 1 and is wound around the winding component 2. The driving motor 22 drives the winding core 21 to rotate (forward), so that the traction rope 23 is gradually released and extends out of the opening 11 below the storage bin 1 under the action of gravity of the grabbing component 3. The cable is then bent and put on the grabbing component 3. The motor 22 is driven again to drive the winding core 21 to rotate (reverse). The traction rope 23 retracts to the storage bin 1, and the grabbing component 3 winds the cable around the winding core 21 together, completing the initialization preparation of the device.

[0025] When the user needs to use the cable for charging, the drive motor 22 is started to drive the winding core 21 to rotate (forward), and the cable extends from the opening 11. A charging gun is connected to one end of the cable. When the cable is extended, the user can use the charging gun to charge. The cable is mounted on the grabbing component 3, and the other end of the cable is connected to the charging pile. The user can drag the cable through the charging gun so that a section of the cable connected to the charging pile also slides along the grabbing component 3 toward the side close to the charging gun, so that the entire cable is stretched and away from the ground. The protective device of the utility model needs to be installed in a position away from the ground, and the cable does not contact the ground when it is extended from the storage bin 1. After charging is completed, the drive motor 22 is started (reverse) to retract the cable again. Through the coordinated implementation of the above-mentioned structure, participants Figure 6 In this embodiment, the winding component 2 can be used to wind the cable in the storage compartment 1 when not in use, thereby avoiding wear and tear of the cable caused by dragging on the ground for a long time, significantly extending the service life of the cable, and avoiding tripping accidents that may be caused by the cable, thereby improving the safety of the charging pile.

[0026] See also Figure 4 - Figure 5The grabbing component 3 includes a pin 31 fixed to the end of the traction rope 23 and a lifting ring 32 hinged by the pin 31. When the cable is installed through the grabbing component 3, the cable is first placed horizontally on one side of the traction rope 23, and the lifting ring 32 is pushed upward so that the cable is clamped between the traction rope 23 and the lifting ring 32. The grabbing component 3 also includes a lock 33, one end of which is provided with two locking tongues 332, and one end of the lifting ring 32 is provided with a notch 321 adapted to the locking tongue 332. The side of the lock 33 close to the locking tongue 332 is pushed toward the traction rope 23, and the lock 33 is pressed downward, and the locking tongue 332 is aligned with the notch 321 of the lifting ring 32 and buckled, so that the lock 33 is sleeved on the traction rope 23 to complete the preliminary fixation. A through hole 331 is opened at one end of the lock 33, and a locking bolt 34 is passed through the through hole 331, and the locking bolt 34 is threadedly connected with the lifting ring 32. The lock buckle 33 in this embodiment is provided with two through holes 331 , and the lifting ring 32 is provided with two threaded holes 322 . The locking bolt 34 passes through the through holes 331 of the lock buckle 33 and is connected and fixed to the lifting ring 32 through the threaded holes 322 , thereby completing the locking operation of the lifting ring 32 .

[0027] The lifting ring 32 is provided with support blocks 323 at the top and bottom, and the support blocks 323 are provided with arc grooves adapted to the outer diameter of the cable. When the cable is fixed, the bent end of the cable is further stretched so that the outer contour of the cable fits with the arc groove and then fixed, ensuring that the cable can fit closely with the arc groove inside the lifting ring 32 when fixed, thereby providing stable support and reducing the wear of the cable during use.

[0028] A circular stop plate 211 is provided at the end of the winding core 21. The winding core 21 is rotatably connected to the storage bin 1, and circular stop plates 211 are provided at both ends of the winding core 21. The circular contour of the circular stop plate 211 is close to the circular inner wall surface of the storage bin 1. When the winding core 21 rotates to wind the cable, the circular stop plate 211 can prevent the cable from detaching from the winding core 21. At the same time, the setting of the circular stop plate 211 can prevent the cable from directly contacting the inner wall of the storage bin 1 during the rotation of the winding core 21, thereby further reducing the wear of the cable.

[0029] A mounting seat 4 is fixed to the rear side of the storage bin 1. The mounting seat 4 is designed with a cylindrical hollow structure. The inner wall surface of the mounting seat 4 away from the storage bin 1 is evenly provided with mounting holes 41 in the circumferential direction, and the side wall surface of the mounting seat 4 is evenly provided with notches 42 in the circumferential direction. In this embodiment, the storage bin 1 is installed on the outside of the charging pile by means of the mounting seat 4, and is specifically connected and fixed to the charging pile by bolts passing through the mounting holes 41. The mounting seat 4 is designed with a cylindrical hollow structure, which helps to reduce the overall weight. The notch 42 is provided to facilitate the tightening force of the bolts by a wrench during installation. A cover plate 5 is provided on the front side of the storage bin 1, and the cover plate 5 is connected to the storage bin 1 in a snap-fit ​​manner for easy maintenance.

[0030] The above contents described in this specification are merely examples of the present utility model. Those skilled in the art of the present utility model may make various modifications or additions to the specific embodiments described, or replace them in similar ways, as long as they do not deviate from the contents of the present utility model specification or exceed the scope defined in the claims, they shall all fall within the protection scope of the present utility model.
