[0031] like Figure 1 and Figure 7As shown, the wire storage and access assembly 10 includes a wire winding rod 101 fixedly connected to the front of the movable block 7, one end of the wire winding rod 101 is fixedly connected to a first fixed plate 102, the first fixed plate 102 is movably connected to a first movable rod 103, one end of the first movable rod 103 is fixedly connected to a driving motor 104, the other end of the first movable rod 103 is rotatably connected to a second movable rod 105, the outer surface of the second movable rod 105 is movably connected to a second fixed plate 106, the outer surface of the first movable rod 103 near the second movable rod 105 is fixedly connected to a driving shaft 107, the outer surface of the driving shaft 107 is fixedly connected to a linkage block, and the outer surface of the driven shaft 108 is fixedly connected to two linkage blocks. The linkage block is provided with a linkage groove, and the linkage rod abuts against the linkage groove. The outer surface of one end of the second movable rod 105 close to the first movable rod 103 is fixedly connected with a driven shaft 108, and one end of the second movable rod 105 is fixedly connected with a motor switch assembly 109, and one end of the motor switch assembly 109 is fixedly connected with a limit plate 110. When the user needs to use the charging gun 4, the charging gun 4 is first pulled out from the inside of the gun holder 3, and then the charging gun 4 is used to drag the charging line 5 to move outward. As the charging line 5 moves outward, the charging line 5 will squeeze the limit plate 110, and the limit plate 110 will synchronously apply force to the third cylinder 1095, and the third cylinder 1095 will synchronously apply force to the second cylinder 1095. The column 1092 applies a force, and the second cylinder 1092 will synchronously apply a force to the extrusion block 1093, and the extrusion block 1093 will squeeze the second spring telescopic rod 1097. The second spring telescopic rod 1097 drives the extrusion block 1093 to separate from the magnet 1096, and drives the extrusion block 1093 to move along the inside of the first cylinder 1091. The movement of the first cylinder 1091 drives the second cylinder 1092, the third cylinder 1095 and the limit plate 110 to move synchronously. As the extrusion block 1093 moves slowly, the extrusion block 1093 drives the extrusion rod to contact and squeeze the pressure-sensitive starter 1094, and the pressure-sensitive starter 1094 triggers the start-up drive motor 104 to rotate at the output end. In one circle, the output end of the driving motor 104 rotates to drive the first movable rod 103 to rotate synchronously inside the first fixed plate 102. The first movable rod 103 rotates to drive the driving shaft 107 to rotate synchronously. Since the driving shaft 107 rotates one circle, it will drive the driven shaft 108 to rotate half a circle. The driven shaft 108 rotates to drive the second movable rod 105 to rotate synchronously inside the second fixed plate 106. The second fixed plate 106 rotates to drive the first cylinder 1091 to rotate synchronously. The first cylinder 1091 rotates to drive the extrusion block 1093 to rotate synchronously. The extrusion block 1093 rotates to drive the second cylinder 1092 to rotate synchronously. The second cylinder 1092 rotates to drive the third cylinder 1095 to rotate synchronously.The rotation of the third cylinder 1095 drives the limit plate 110 to rotate synchronously, so that the limit plate 110 rotates half a circle. After the limit plate 110 rotates, the top point of the limit plate 110 and the top point of the winding rod 101 are located on the same horizontal line. Since the charging cable 5 is no longer limited by the limit plate 110, the charging cable 5 falls along the surface of the winding rod 101 under the drive of the charging gun 4, and the charging cable 5 can be quickly removed from the surface of the winding rod 101, effectively avoiding the inconvenience caused by manual winding and pulling of the charging cable 5, thereby significantly improving the efficiency and convenience of the charging experience.

[0032] like Figure 1 and Figure 6 As shown, a moving rod 12 is fixedly connected to the top of the slider 9, and the moving rod 12 is movably connected to the inside of the pile body 1. A partition 13 is fixedly connected to the top of the moving rod 12, and the outer surface of the partition 13 is movably connected to the inside of the pile body 1. A rubber pad 14 is bonded to the top of the partition 13. When the charging wire 5 is removed, the surface of the winding rod 101 is no longer subjected to the gravity of the charging wire 5, and the gravity of the movable block 7 decreases. Under the elastic force of the first spring telescopic rod 8, the movable block 7 is driven to move upward. The movement of the movable block 7 drives the slider 9 to slide synchronously inside the pile body 1. The movement of the movable block 7 drives the moving rod 12 to move synchronously. The movement of the moving rod 12 drives the partition 13 to move synchronously inside the slide groove. The movement of the partition 13 drives the rubber pad 14 to move synchronously. When the rubber pad 14 is in compression contact with the outer surface of the pile body 1, the partition 13 stops moving. The partition 13 can isolate and protect the gun seat 3 in an outdoor environment.

[0033] like Figure 1 and Figure 8As shown, the wire management detection assembly 11 includes a fixed block 111 fixedly connected to the back of the movable block 7, one end of the fixed block 111 is fixedly connected to the first movable plate 112, the back of the fixed block 111 is movably connected to the second movable plate 113 through a pin shaft, one end of the first movable plate 112 is movably connected to the third movable plate 114 through a pin shaft, one end of the third movable plate 114 is movably connected to the extrusion plate 115 through a pin shaft, one end of the second movable plate 113 is movably connected to the outer surface of the extrusion plate 115 through a pin shaft, and the inside of the second movable plate 113 is movably connected to the fourth movable plate 116 through a pin shaft One end of the fourth movable plate 116 is movably connected to a positioning block 117 through a pin shaft, one end of the positioning block 117 is fixedly connected to the inside of the pile body 1, the outer surface of the extrusion plate 115 is fixedly connected to a displacement block 118, the outer surface of the displacement block 118 is slidably connected to a slide rail 119, one end of the slide rail 119 is fixedly connected to the inside of the pile body 1, and pressure switches 120 are fixedly installed at both ends of the extrusion plate 115 inside the pile body 1. The pressure switch 120 is electrically connected to the control unit inside the pile body 1. When the user uses the charging gun 4 to charge the electric car, first, the charging line 5 is overlapped on the outside of the winding rod 101 The surface of the winding rod 101 is subjected to the gravity of the charging line 5, which will apply a force to the movable block 7, so that the movable block 7 squeezes the first spring telescopic rod 8 and drives the movable block 7 to move downward along the movable groove 6. The downward movement of the movable block 7 will drive the fixed block 111 to move synchronously, and the movement of the fixed block 111 will drive the first movable plate 112 to move synchronously. As the first movable plate 112 and the fixed block 111 move slowly, the second movable plate 113 and the third movable plate 114 will rotate through the pin shaft, and the rotation of the second movable plate 113 will drive the fourth movable plate 116 to rotate synchronously through the pin shaft. As the second movable plate 113 and the third movable plate 114 rotate, the squeezing plate 115 will move in the horizontal direction. The movement of the squeezing plate 115 will drive the displacement block 118 to slide synchronously inside the slide rail 119. When the squeezing plate 115 contacts the pressure switch 120 at one end, the charging gun 4 can be returned. This can avoid the phenomenon of randomly throwing away the charging gun 4, and can also prevent some users from placing the charging cable 5 at will, thereby improving the aesthetics of the environment around the charging pile, greatly reducing safety hazards, and effectively improving the cleanliness and safety of the charging pile equipment and the public environment.

[0034] like Figure 1 and Fig. 9 As shown, the shape of the extrusion plate 115 is an I-shape, and both ends of the extrusion plate 115 are located on the same horizontal line as the pressure switch 120, ensuring that the extrusion plate 115 can contact and trigger the pressure switch 120 when moving in the horizontal direction, ensuring that the extrusion plate 115 can be used normally.

[0035] like Figure 1 and Fig.11As shown, the motor switch assembly 109 includes a first cylinder 1091 fixedly connected to one end of the second movable rod 105, a second cylinder 1092 is movably connected inside the first cylinder 1091, an extrusion block 1093 is fixedly connected to one end of the second cylinder 1092, a magnet 1096 is fixedly connected to the first cylinder 1091 at a position above the extrusion block 1093, the extrusion block 1093 is made of iron, the extrusion block 1093 is attached to the outer surface of the magnet 1096, and the second cylinder 1092 is fixedly connected to one end of the second cylinder 1092. A pressure-sensitive starter 1094 is fixedly connected to one end of the extrusion block 1093, and an extrusion rod is fixedly connected to one end of the extrusion block 1093 near the pressure-sensitive starter 1094. A second spring telescopic rod 1097 is fixedly connected to one end of the extrusion block 1093 below the extrusion rod. One end of the second spring telescopic rod 1097 is fixedly connected to the inside of the first cylinder 1091, and one end of the second cylinder 1092 is fixedly connected to the third cylinder 1095. When the charging cable 5 is dragged outward by the charging gun 4, The charging cable 5 is dragged outward by the charging gun 4. As the charging cable 5 moves outward, the charging cable 5 squeezes the limit plate 110. The limit plate 110 simultaneously applies a force to the third cylinder 1095. The third cylinder 1095 simultaneously applies a force to the second cylinder 1092. The second cylinder 1092 simultaneously applies a force to the squeezing block 1093. The squeezing block 1093 squeezes the second spring telescopic rod 1097. The second spring telescopic rod 1097 drives the squeezing block 1093 and the magnet 1097. 96 are separated, driving the extrusion block 1093 to move along the inside of the first cylinder 1091. The movement of the first cylinder 1091 drives the second cylinder 1092, the third cylinder 1095 and the limit plate 110 to move synchronously. As the extrusion block 1093 moves slowly, the extrusion block 1093 will drive the extrusion rod to contact and squeeze the pressure-sensitive starter 1094. The pressure-sensitive starter 1094 triggers the output end of the start drive motor 104 to rotate one circle, which can realize the automatic start of the drive motor 104 and simplify the operation process.

[0036] like Figure 1 and Fig.10 As shown, the third cylinder 1095 is fixedly connected to a position slightly below the center of the limiting disk 110, and the bottom end of the wire winding rod 101 and the bottom end of the limiting disk 110 are located on the same horizontal line, ensuring that when the limiting disk 110 rotates half a circle, the top end of the wire winding rod 101 and the top end of the limiting disk 110 are located on the same horizontal line, thereby achieving the purpose of facilitating the removal of the charging cable 5.

[0037] like Figure 1 and Figure 3 As shown, slide grooves are provided inside the pile body 1 at both sides of the gun seat 3, and the outer surface of the partition 13 is slidably connected to the inside of the slide groove, so that the partition 13 can move stably along the slide groove, thereby improving the stability and reliability of the movement of the partition 13.

[0038] like Figure 1 and Figure 2 As shown, the horizontal distance between the two slide grooves is equal to the width of the partition 13, the top of the rubber pad 14 fits with the outer surface of the pile body 1, and the partition 13 and the rubber pad 14 can form a closed space with the outer surface of the pile body 1, ensuring that the gun seat 3 is not damaged by wind and rain in the outdoor environment, effectively improving the service life of the gun seat 3.

[0039] Working principle: During actual use of the device, when the user needs to use the charging gun 4, he first pulls the charging gun 4 out of the gun holder 3, and then uses the charging gun 4 to drag the charging cable 5 to move outward. As the charging cable 5 moves outward, the charging cable 5 will squeeze the limit plate 110, and the limit plate 110 will synchronously apply a force to the third cylinder 1095, and the third cylinder 1095 will synchronously apply a force to the second cylinder 1092, and the second cylinder 1092 will synchronously apply a force to the extrusion block 1093, and the extrusion block 1093 will squeeze the second spring telescopic rod 1097, and the second spring telescopic rod 1097 drives the extrusion block 1093 to separate from the magnet 1096, and drives the extrusion block 1093 to move along the inside of the first cylinder 1091, and the movement of the first cylinder 1091 drives the second cylinder 1092, the third cylinder 1095 and the limit plate 110 to move synchronously. The squeezing block 1093 moves slowly, and the squeezing block 1093 drives the squeezing rod to contact and squeeze the pressure-sensitive starter 1094. The pressure-sensitive starter 1094 triggers the start of the output end of the driving motor 104 to rotate one circle. The output end of the driving motor 104 rotates to drive the first movable rod 103 to rotate synchronously inside the first fixed plate 102. The first movable rod 103 rotates to drive the driving shaft 107 to rotate synchronously. Since the driving shaft 107 rotates one circle, it will drive the driven shaft 108 to rotate half a circle. The driven shaft 108 rotates to drive the second movable rod 105 to rotate synchronously inside the second fixed plate 106. The rotation of the second fixed plate 106 drives the first cylinder 1091 to rotate synchronously. The rotation of the first cylinder 1091 drives the squeezing block 1093 to rotate synchronously. The rotation of the squeezing block 1093 drives the second cylinder 1092 to rotate synchronously. The rotation of the second cylinder 1092 drives the third cylinder 1095 to rotate synchronously.The rotation of the third cylinder 1095 drives the limit plate 110 to rotate synchronously, so that the limit plate 110 rotates half a circle. After the rotation of the limit plate 110 is completed, the top point of the limit plate 110 and the top point of the winding rod 101 are located on the same horizontal line. Since the charging cable 5 is no longer limited by the limit plate 110, the charging cable 5 falls along the surface of the winding rod 101 driven by the charging gun 4. At this time, since the surface of the winding rod 101 no longer bears the gravity of the charging cable 5, the gravity of the movable block 7 decreases, and the elastic force of the first spring telescopic rod 8 drives the movable block 7 to move upward. The movement of the movable block 7 drives the slider 9 to slide synchronously inside the pile body 1. The movement of the movable block 7 drives the movable rod 12 to move synchronously. The movement of the movable rod 12 drives the partition 13 to move synchronously inside the slide groove. The movement of the partition 13 drives the rubber pad 14 to move synchronously. When the rubber pad 14 is squeezed and contacted with the outer surface of the pile body 1, the partition 13 stops moving. The partition 13 can isolate and protect the gun holder 3 in an outdoor environment. At this time, the charging gun 4 can be used to charge the electric vehicle. Then, because the charging line 5 no longer applies force to the limit plate 110, the elastic force of the second spring telescopic rod 1097 drives the extrusion block 1093 to move outward. When the extrusion block 1093 reaches the position below the magnet 1096, the extrusion block 1093 adheres to the surface of the magnet 1096. At this time, the extrusion block 1093 drives the second cylinder 1092, the third cylinder 1095 and the limit plate 110 to reset, and the charging line 5 can be quickly removed from the surface of the winding rod 101, effectively avoiding the inconvenience caused by manual winding and pulling of the charging line 5, thereby significantly improving the efficiency and convenience of the charging experience, making the charging process more automated, simple and fast, and can also isolate and protect the gun holder 3, thereby increasing the service life of the gun holder 3;

[0040] Then, when the user uses the charging gun 4 to charge the electric car, the charging line 5 is first overlapped on the outer surface of the winding rod 101. Since the surface of the winding rod 101 bears the gravity of the charging line 5, a force is applied to the movable block 7, so that the movable block 7 squeezes the first spring telescopic rod 8 and drives the movable block 7 to move downward along the movable groove 6. The downward movement of the movable block 7 drives the fixed block 111 to move synchronously, and the movement of the fixed block 111 drives the first movable plate 112 to move synchronously. As the first movable plate 112 and the fixed block 111 move slowly, the second movable plate 113 and the third movable plate 114 will rotate through the pin shaft, and the second movable plate 113 The rotation will drive the fourth movable plate 116 to rotate synchronously through the pin shaft. As the second movable plate 113 and the third movable plate 114 rotate, the extrusion plate 115 will move in the horizontal direction. The movement of the extrusion plate 115 will drive the displacement block 118 to slide synchronously inside the slide rail 119. When the extrusion plate 115 contacts the pressure switch 120 at one end, the charging gun 4 can be returned, which can avoid the phenomenon of the charging gun 4 being thrown away or placed randomly, and can also prevent some users from placing the charging cable 5 at will, thereby improving the aesthetics of the environment around the charging pile, greatly reducing safety hazards, and effectively improving the cleanliness and safety of the charging pile equipment and the public environment.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
