[0003] A group of charging piles are designed in the related technology, and the charging cables connecting the electric guns and the charging piles are placed randomly. When taking and storing the charging guns, the charging cables rub against the ground, causing wear on the charging cables and reducing the service life of the charging cables. Therefore, there is room for improvement. Summary of the invention

[0006] By adopting the above technical solution, after the user parks the car next to the cabinet, he uses the control panel on the cabinet to operate, first disengage the charging gun from the interface on the cabinet, and then control the telescopic component to work. The telescopic component drives the secondary board to slide on the primary board while the tertiary board slides on the secondary board, so that the primary board, the secondary board and the tertiary board gradually unfold, driving the guide wheel on the tertiary board to gradually move away from the cabinet. The telescopic component works and the retractable component works at the same time. The retractable component drives the clamping roller to rotate, and the clamping roller uses friction to gradually release the charging line in the line storage box, so that the charging gun can gradually move away from the cabinet under the guide wheel. When the charging gun moves to the position where charging is required, the telescopic component is controlled to stop working; after charging is completed, the telescopic component drives the primary board, the secondary board and the tertiary board to retract, and the retractable component retracts the charging line into the line storage box. During the whole process, the charging line is located on the primary board, the secondary board and the tertiary board, and the charging gun hangs below the guide wheel to avoid damage to the charging line due to friction with the ground, thereby protecting the charging line and extending the service life of the charging line.

While the secondary plate slides, since the chain is fixed to the positioning block, the chain is subjected to tension, and the chain will be transmitted on the sprocket, thereby driving the sprocket to rotate. While the chain is transmitting, the linkage block is subjected to force, driving the tertiary plate to slide on the secondary plate along its length direction, so that the second plate can be controlled to slide on the primary plate while the tertiary plate slides on the secondary plate only by the first motor, which effectively expands the retracting and extending distance of the charging gun, and is easy to control and low in cost.

[0012] By adopting the above technical solution, when the charging cable is recovered into the cable storage box, the counterweight block drives the abutment wheel to abut against the charging cable. Due to the large weight of the counterweight block, the counterweight block continues to descend on the guide rod under the action of gravity. The configuration block arranges the charging cable in a "V" shape in the cable storage box, automatically and quickly arranging the recovered charging cable, reducing the phenomenon of disorderly arrangement of the charging cable in the cable storage box, and orderly recovering and storing the charging cable, which is conducive to further extending the service life of the charging cable.

[0013] Preferably, an oil filling hole is provided on the surface of the counterweight block.

[0014] By adopting the above technical solution, lubricating oil can be injected into the space between the configuration block and the guide rod through the oil filling hole, thereby reducing the friction between the configuration block and the guide rod, ensuring that the configuration block can have a good pressing and organizing effect on the charging cable, and facilitating maintenance of the equipment.

The second motor is used to drive the second screw rod to rotate, and the wire storage box is guided by the transverse rod. The wire storage box can slide horizontally on the transverse rod. The sliding assembly is used to change the position of the wire storage box on the mounting frame. The telescopic assembly can further expand the displacement position of the charging gun, which is convenient for charging different models of cars and improves the applicability of the charging pile.

[0018] Preferably, a bearing is provided at one end of the wire storage box facing the cabinet, the outer ring of the bearing is fixed to the cabinet, the charging wire passes through the bearing, and the charging wire and the inner ring of the bearing are fixed to each other; a support cylinder is rotatably provided on the side wall of the wire storage box and located above the bearing, the charging wire passes through the support cylinder, and a bending rod is fixedly provided on the top of the cabinet to resist the support cylinder, and the bending rod is high in the middle and low at both ends.

[0019] By adopting the above technical scheme, since the connection between the charging cable and the cabinet is located at the center of the top of the cabinet, when the sliding assembly drives the wire storage box to slide horizontally on the transverse rod, the bearing rotates, so that the charging cable can adapt to different positions on the wire storage box, and at the same time, the bending rod and the support tube are abutted, the bending rod is higher in the middle and lower at both ends, and the support tube slides on the bending rod. When the wire storage box is close to the middle of the cabinet, the support tube rotates and rises, and when the wire storage box is close to both ends of the cabinet, the support tube rotates and descends, so that the charging cable between the cabinet and the wire storage box remains taut, the charging cable is sorted, the charging cable is further protected, and the phenomenon of accidental contact of the charging cable is reduced.

The telescopic component drives the secondary board to slide on the primary board while the tertiary board slides on the secondary board. At the same time, the retractable component drives the clamping roller to rotate. The clamping roller gradually releases the charging line in the line storage box, so that the charging gun can gradually move away from the cabinet under the guide wheel. When the charging gun moves to the position where charging is required, the telescopic component is controlled to stop working. During the whole process, the charging line is located on the primary board, the secondary board and the tertiary board, and the charging gun hangs under the guide wheel to avoid damage to the charging line due to friction with the ground, thereby protecting the charging line and extending the service life of the charging line. 2.

A charging gun 31 is provided at the end of the charging cable 3, and an interface 311 for the charging gun 31 to be inserted and fixed is provided on the cabinet 1. When the charging pile is not in use, the charging gun 31 is inserted into the interface 311.

[0029] Reference Figures 1 to 4 A group of clamping rollers 4 are symmetrically arranged in the wire storage box 11 for rotation. The surface of the clamping rollers 4 is made of flexible rubber material. The charging line 3 passes through the two clamping rollers 4, and the clamping rollers 4 are against the charging line 3. A retractable assembly is arranged on the wire storage box 11. After the user parks the car next to the cabinet 1, he uses the control panel on the side wall of the cabinet 1 to operate. First, the charging gun 31 and the interface 311 on the cabinet 1 are separated from each other. Then, the user can control the telescopic assembly to work through the mobile phone while holding the charging gun 31 with one hand. The telescopic assembly drives the secondary board 22 to slide on the primary board 21 while the tertiary board 23 slides on the secondary board 22, so that the primary board 21, the secondary board 22 and the tertiary board 23 gradually expand, driving the guide wheel 231 on the tertiary board 23 to gradually move away from the cabinet 1. The telescopic assembly works while the retractable assembly works. The retractable assembly brings The dynamic clamping roller 4 rotates, and the clamping roller 4 uses friction to gradually release the charging line 3 in the line storage box 11, so that the charging gun 31 can gradually move away from the cabinet 1 under the guide wheel 231, and the telescopic component is controlled to stop working when the charging gun 31 moves to the position where charging is required; after charging is completed, the telescopic component drives the primary board 21, the secondary board 22 and the tertiary board 23 to retract, and at the same time, the retractable component retracts the charging line 3 into the line storage box 11. During the whole process, the charging line 3 is located on the primary board 21, the secondary board 22 and the tertiary board 23, and the charging gun 31 is hung below the guide wheel 231 for use, so as to avoid the charging line 3 being damaged by friction with the ground.

[0030] Reference Figure 3 The telescopic assembly includes a first motor 51, a first screw rod 52, a sprocket 53, a chain 54, a positioning block 55 and a linkage block 56. The first motor 51 is fixedly arranged on the outer wall of the wire storage box 11 by bolts, the first screw rod 52 is rotatably arranged on the primary plate 21, the length direction of the first screw rod 52 is arranged along the length direction of the primary plate 21, the driving shaft of the first motor 51 is connected to the first screw rod 52, and the secondary plate 22 is threadedly connected to the first screw rod 52. Two sprocket wheels 53 are symmetrically rotatably arranged at both ends of the secondary plate 22, the chain 54 is jointly sleeved and meshed on the two sprocket wheels 53, the positioning block 55 is fixedly arranged on the primary plate 21 and one end away from the cabinet 1, the positioning block 55 and one side of the chain 54 are fixed to each other, the linkage block 56 is fixedly arranged on the tertiary plate 23 and one end close to the cabinet 1, the linkage block 56 and the other side of the chain 54 are fixed to each other, and the positioning block 55 is located above the linkage block 56. After the charging gun 31 is disconnected from the interface 311, the user controls the first motor 51 to work, and uses the first motor 51 to drive the first screw rod 52 to rotate. The secondary plate 22 is guided and slides on the primary plate 21 along its length direction. While the secondary plate 22 slides, since the chain 54 is fixed to the positioning block 55, the chain 54 is subjected to tension, and the chain 54 will be transmitted on the sprocket 53, thereby driving the sprocket 53 to rotate. While the chain 54 is transmitting, the linkage block 56 is subjected to force, driving the tertiary plate 23 to slide on the secondary plate 22 along its length direction. Therefore, the second plate 22 can be controlled to slide on the primary plate 21 while the tertiary plate 23 slides on the secondary plate 22 only by the first motor 51, which effectively expands the retractable distance of the charging gun 31, makes the control convenient and quick, and effectively utilizes the space.

[0031] Reference Figure 3 and Figure 4 The retractable assembly includes a worm wheel 61 and a worm 62. The worm 62 is connected to the drive shaft of the first motor 51. The worm 62 is arranged on the surface of the first screw 52 and is coaxially arranged. The worm 62 is coaxially arranged with the first screw 52. The worm wheel 61 is connected to the end wall of one of the clamping rollers 4. The worm wheel 61 is coaxially arranged with the clamping roller 4 connected to it. The worm wheel 61 penetrates the wire storage box 11 and meshes with the worm 62. When the first motor 51 drives the screw to rotate to control the telescopic assembly to work, the first motor 51 drives the worm 62 to rotate, the worm 62 and the worm wheel 61 are against each other, and drive one of the clamping rollers 4 to rotate. The clamping roller 4 uses friction to drive the charging line 3 to retract and release. In this way, the clamping roller 4 is automatically driven to rotate while controlling the telescopic assembly to work, so that synchronous work is achieved and the device cost is saved.

An abutment wheel 72 is rotatably arranged on the counterweight block 71, and the abutment wheel 72 abuts against the charging line 3. When the charging line 3 is recovered into the wire storage box 11, the counterweight block 71 drives the abutment wheel 72 to abut against the charging line 3. Due to the large weight of the counterweight block 71, the counterweight block 71 continuously descends on the guide rod 7 under the action of gravity, and the configuration block arranges the charging line 3 in a "V" shape in the wire storage box 11, automatically and quickly arranges the recovered charging line 3, reduces the phenomenon of the charging line 3 being arranged in a disorderly manner in the wire storage box 11, and orderly recycles and stores the charging line 3, which is conducive to further extending the service life of the charging line 3.

The wire storage box 11 is threadedly connected with the second screw rod 92, and the driving shaft of the second motor 91 is connected with the second screw rod 92. When the user parks at the charging pile, he may reverse or drive directly into the parking space. Therefore, the position required for connection with the car charging is not fixed. The second motor 91 is used to drive the second screw rod 92 to rotate, and the wire storage box 11 is guided by the transverse rod 81. The wire storage box 11 can slide horizontally on the transverse rod 81. The sliding assembly is used to change the position of the wire storage box 11 on the mounting frame 8. The telescopic assembly can further expand the displacement position of the charging gun 31, which is convenient for charging different models of cars and improves the applicability of the charging pile.

[0034] Reference Figure 1 and Figure 4A bearing 111 is provided at one end of the wire storage box 11 facing the cabinet 1. The outer ring of the bearing 111 is welded and fixed to the cabinet 1. The charging line 3 passes through the bearing 111. The charging line 3 and the inner ring of the bearing 111 are bonded and fixed to each other. A support cylinder 12 is provided on the side wall of the wire storage box 11 above the bearing 111 and is rotated by a hinge. The support cylinder 12 can be rotated away from the cabinet 1, and the charging line 3 passes through the support cylinder 12.

The length direction of the bending rod 10 is arranged along the width direction of the cabinet 1, and the bending rod 10 is arranged to be high in the middle and low at both ends. Since the connection between the charging cable 3 and the cabinet 1 is located at the center of the top of the cabinet 1, when the sliding assembly drives the wire storage box 11 to slide horizontally on the transverse rod 81, the bearing 111 rotates, so that the charging cable 3 can adapt to different positions on the wire storage box 11, and at the same time, the bending rod 10 is against the support tube 12, and the support tube 12 slides on the bending rod 10.

At the same time, it is beneficial to appearance and low cost.

[0035] The implementation principle of a new energy vehicle charging pile in the embodiment of the present application is as follows: after the user parks the electric car next to the cabinet 1, the user uses the control panel on the side wall of the cabinet 1 to operate, first disengages the charging gun 31 from the interface 311 on the cabinet 1, and uses a mobile phone to scan the code to control the first motor 51 to work.

While the chain is transmitting, the linkage block 56 is subjected to force , driving the tertiary plate 23 to slide on the secondary plate 22 along its length direction, so that the primary plate 21, the secondary plate 22 and the tertiary plate 23 are gradually unfolded, driving the guide wheel 231 on the tertiary plate 23 to gradually move away from the cabinet 1; at the same time, the first motor 51 drives the worm 62 to abut against the worm wheel 61, and controls one of the clamping rollers 4 to rotate. The clamping roller 4 uses friction to gradually release the charging line 3 in the line storage box 11, so that the charging gun 31 can gradually move away from the cabinet 1 under the guide wheel 231. When the charging gun 31 moves to the position where charging is required, the telescopic assembly is controlled to stop working. At this time, the suspended charging gun 31 is connected to the charging port on the car. After charging is completed, the telescopic component drives the primary plate 21, the secondary plate 22 and the tertiary plate 23 to retract, and at the same time the retractable component retracts the charging cable 3 into the cable storage box 11.
