[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] The present invention will be described in further detail below with reference to the accompanying drawings.

[0027] Example 1: Please refer to Figure 1-5The utility model provides a charging pile with a retractable charging gun line. In order to improve the convenience and neatness of the charging pile, a cable storage mechanism 2 is provided on the charging pile body 1, including the charging pile body 1, a charging gun 11, a charging cable 12, and the cable storage mechanism 2. The charging pile body 1 is provided with a gun groove 13 for placing the charging gun 11, and the gun groove 13 is arranged close to the cable storage mechanism 2. The cable storage mechanism 2 includes a box body 21 and a retractor 22. The retractor 22 is installed inside the box body 21. The retractor 22 is used to retract the charging cable 12 inside the box body 21. One end of the charging cable 12 extending from the box body 21 is connected to the charging gun 11, and the end of the charging cable 12 is connected to the inside of the charging pile body 1. The charging cable 12 extends from the outer wall of the charging pile body 1 and is stored through the retractor 22. The retractor 22 includes a rotating shaft 221 and a winding spring 222. The two ends of 21 are installed in the box body 21 through bearings. The partition plates 223 are symmetrically provided on the rotating shaft 221. The partition plates 223 divide the rotating shaft 221 into three areas. The three areas of the rotating shaft 221 from left to right are respectively used to install the coil spring 222, the charging line 12 and the locking member 3 for locking the rotating shaft 221. When in use, the charging gun 11 is taken out of the gun slot 13, and then the charging line 12 is pulled until the charging gun 11 is inserted into the vehicle charging station. The rotating shaft 221 is limited and locked by the locking member 3 to prevent the rotating shaft 221 from rotating. When charging is completed, the restriction on the rotating shaft 221 is released by controlling the locking member 3, and the rotating shaft 221 is driven to rotate under the action of the winding spring 222 to realize automatic reeling of the charging cable 12. There is no need for manual reeling, thereby improving work efficiency. When the reeling is completed, the locking member 3 is controlled to lock and fix the rotating shaft 221, and then the charging gun 11 is inserted into the gun slot 13 to complete the entire operation.

[0028] In this embodiment, a cable storage mechanism 2 is provided on the charging pile body 1, so that the user can store the charging cable 12 into the cable storage mechanism 2 after charging is completed. By storing the charging cable 12, the convenience and neatness of the charging pile can be improved, and the problem of the charging gun 11 cable being placed in a disorderly manner can be avoided. The retractor 22 and the locking member 3 provided in the cable storage mechanism 2 can be controlled by the locking member 3 to reel and lock the retractor 22, so that after the use of the charging cable 12 is completed, the control mechanism 4 in the locking member 3 can be operated to realize the automatic storage function of the charging cable 12, reducing the trouble of the user manually arranging the charging gun 11 cable and improving the charging efficiency. Furthermore, by storing the charging cable 12, it is avoided that it is exposed to the sun and rain for a long time, which is beneficial to increasing the service life of the charging cable 12. At the same time, it also avoids the charging cable 12 being exposed to the ground for a long time, causing the charging cable 12 to be dirty, dirtying the user's hands and affecting the user's experience.

[0029] Example 2: Based on Example 1, in this example, Figure 2-5 As shown, a limit cover 224 is further provided between the partition and the inner wall of the box body 21, and a clamping fixing groove 225 is opened at one end of the rotating shaft 221 connected to the coil spring 222. The starting end of the coil spring 222 is clamped and fixed with the fixing groove 225. The coil spring 222 is coiled in the limit cover 224. A through groove 226 is provided on the area of the rotating shaft 221 for winding the charging line 12. The charging line 12 passes through the through groove 226, and the rotating shaft 221 is rotated to The charging cable 12 of the extended charging pile body 1 is wound between the two partitions. By setting a limit cover 224 at both ends of the rotating shaft 221, the coil spring 222 or the locking member 3 can be installed inside it, which can not only limit the coil spring 222 and the locking member 3, but also avoid affecting the operation of the coil spring 222 and the locking member 3 during winding. A fixing groove 225 and a through groove 226 are set on the rotating shaft 221 to facilitate the coil spring 222 and the charging cable 12 to rotate with the rotating shaft 221.

[0030] The box body 21 is further provided with a plurality of auxiliary rollers 23, which are rotatably mounted between the inner walls of the box body 21. The auxiliary rollers 23 are staggered, and the charging line 12 extending out of the partition is S-shaped and passes around each of the auxiliary rollers 23 in turn. The box body 21 is provided with a wire outlet 24, and the end of the charging line 12 passes through the wire outlet 24 and is connected to the charging gun 11. By arranging a plurality of auxiliary rollers 23 inside the box body 21, the stability of the charging line 12 can be increased, and the twisting and rupture of the charging line 12 during the winding process can be reduced. At the same time, by allowing the charging cable 12 to move between multiple auxiliary rollers 23 in an interlaced manner, an S-shaped path is formed, thereby effectively dispersing the tension of the charging cable 12, making it smoother and more orderly when reeling. The S-shaped path design makes the charging cable 12 more uniform when reeling, avoiding the inefficiency caused by local over-tightening or over-loosening, thereby improving the overall reeling speed and efficiency. Through the design of staggered auxiliary rollers 23, the cable can move more smoothly during the reeling process, reducing the wear and damage caused by direct friction with the reel, and extending the service life of the charging cable 12.

[0031] The locking member 3 includes a ratchet 31, a pawl 32, and an elastic pressing piece 33. The ratchet 31 is fixedly connected to the end of the rotating shaft 221. The pawl 32 is movably mounted on the inner wall of the box body 21 through a pin. The elastic pressing piece 33 is rotatably mounted on the inner wall of the box body 21 on the side opposite to the pawl 32. The end of the elastic pressing piece 33 presses the pawl 32. The box body 21 is also provided with a control mechanism 4 for unlocking the pawl 32. When the rotating shaft 221 rotates, the ratchet connected to the end of the rotating shaft 221 31 follows the rotation. When the shaft 221 stops rotating, the pawl 32 limits and fixes the ratchet 31 in the direction opposite to the rotation direction of the shaft 221, and presses against the wheel groove of the ratchet 31. At this time, the elastic pressing piece 33 presses against the pawl 32. When it is necessary to release the restriction on the ratchet 31, the control mechanism 4 pushes one end of the pawl 32 downward to disengage the pawl 32 from the wheel groove of the ratchet 31, thereby releasing the restriction on the ratchet 31. The winding spring 222 drives the shaft 221 to rotate, thereby realizing automatic reeling of the charging cable 12 and improving the reeling efficiency.

[0032] Example 3: Based on Example 1, in this example, Figure 3-5 As shown, the control mechanism 4 includes a telescopic column 41 and a limit plate 42. The limit plate 42 is installed at the end of the rotating shaft 221 and is not fixedly connected to the outer wall of the bearing connected to the end of the rotating shaft 221. The limit plate 42 is provided with a limit groove 43 for limiting one end of the pawl 32. The telescopic column 41 is arranged above the limit groove 43, and the top end of the telescopic column 41 extends out of the top of the box body 21.

[0033] The telescopic column 41 includes a hollow sleeve 411 and a movable column 412. The hollow sleeve 411 and the movable column 412 are socketed together. The outer wall of the movable column 412 is provided with a guide column 413. The outer wall of the hollow sleeve 411 is provided with an arc-shaped sliding groove 414 that cooperates with the guide column 413. The hollow sleeve 411 is rotatably installed on the top of the box body 21 and is not separated from the box body 21. The movable column 412 is controlled to extend and retract on the hollow sleeve 411 by rotating the hollow sleeve 411. The movable column 412 is arranged above one end of the pawl 32.

[0034] A limiting ring 416 is provided on the outer wall of the hollow sleeve 411, and a handle 415 is provided on the top of the hollow sleeve 411. The handle 415 is fitted with the top of the box body 21, and a pointing arrow is provided on the top of the handle 415. The top of the box body 21 is provided with unlocking and locking letter logos that match the arrows and are located on both sides of the handle 415. The limiting ring 416 and the handle 415 are pressed against the inner and outer walls of the top of the box body 21 for limiting the position. The limiting ring 416 is provided with a through hole for the movable column 412 to pass through.

[0035] When in use, when the charging cable 12 is pulled outward, the ratchet 31 is not restricted by the clamping claw. When the charging cable 12 needs to be retracted, the hollow sleeve 411 is rotated to make the movable column 412 move along the slide groove 414 on the hollow sleeve 411 under the action of its guide column 413, thereby pushing the movable column 412 to move in the direction of the limit groove 43 until it moves to the guide column 413 and the end of the slide groove 414 is tightly pressed. At this time, the movable column 412 has pushed the end of the ratchet 32 that is not in contact with the ratchet 31 downward to rotate around the axis, so that the end of the ratchet 32 that is engaged with the ratchet 31 is disengaged from the ratchet 31, thereby releasing the restriction on the ratchet 31 and facilitating the recycling of the charging cable 12. In this embodiment, the user is prompted by the pointing arrow on the handle 415 and the unlocking and locking marks on the box body 21, so that the user can adjust the hollow sleeve 411 to unlock and lock the ratchet 31.

[0036] The above description of the present invention is illustrative in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
