Description

Technical Field

[0001] The present invention relates to the technical field of vehicle charging piles, and more particularly to a new energy vehicle charging pile. Background Art

[0002] Currently, the charging pile is similar in function to the fuel dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings and parking lots or charging stations in residential communities, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles.

[0003] In the related art, there is a group of charging piles, and the charging cables connecting the charging guns to the charging piles are randomly placed. When taking and storing the charging guns, the charging cables rub against the ground, causing wear to the charging cables and reducing the service life of the charging cables. Therefore, improvement is needed. Summary of the Invention

[0004] In order to reduce the friction between the charging cable and the ground when the charging gun is in use and extend the service life of the charging cable, the present application provides a new energy vehicle charging pile.

[0005] A new energy vehicle charging pile provided by the present application adopts the following technical solutions:

[0006] A new energy vehicle charging pile includes a cabinet for power supply. A wire storage box is provided on the cabinet. A first-level plate is fixedly provided on the side wall of the wire storage box. A second-level plate is slidably provided on the side wall of the first-level plate. A third-level plate is slidably provided on the side wall of the second-level plate. The length directions of the first-level plate, the second-level plate, and the third-level plate are parallel to each other. A telescopic assembly is provided on the wire storage box. The telescopic assembly is used to drive the second-level plate to slide on the first-level plate while the third-level plate slides on the second-level plate. A charging cable is provided at the top of the cabinet. A guide wheel is rotatably provided at the end of the third-level plate. The charging cable passes through the wire storage box and is wound around the guide wheel. A charging gun is provided at the end of the charging cable. An interface for inserting and fixing the charging gun is provided on the cabinet. A group of clamping rollers are symmetrically and rotatably provided in the wire storage box. The charging cable passes through the two clamping rollers, and the clamping rollers are in contact with the charging cable. A winding and unwinding assembly is provided on the wire storage box. The winding and unwinding assembly is used to drive one of the clamping rollers to rotate when the telescopic assembly works.

[0007] By adopting the above technical solution, after the user parks the vehicle beside the cabinet, the user operates through the control panel on the cabinet. First, the charging gun is disengaged from the interface on the cabinet, and then the telescopic assembly is controlled to work. While the telescopic assembly drives the secondary plate to slide on the primary plate, the tertiary plate slides on the secondary plate, causing the primary plate, secondary plate, and tertiary plate to gradually unfold, driving the guide wheels on the tertiary plate to gradually move away from the cabinet. While the telescopic assembly is working, the retracting and releasing assembly works, driving the clamping rollers to rotate. The clamping rollers use friction to gradually release the charging cable in the cable storage box. Thus, the charging gun can gradually move away from the cabinet under the guide wheels. When the charging gun moves to the position where charging is required, the telescopic assembly is controlled to stop working; after charging is completed, the telescopic assembly drives the primary plate, secondary plate, and tertiary plate to retract, and at the same time, the retracting and releasing assembly retracts the charging cable into the cable storage box. During the whole process, the charging cable is located on the primary plate, secondary plate, and tertiary plate, and the charging gun hangs under the guide wheels, avoiding the situation where the charging cable is damaged by rubbing against the ground, thereby protecting the charging cable and being beneficial to extending the service life of the charging cable.

[0008] Preferably, the telescopic assembly includes a first motor, a first lead screw, sprockets, a chain, a positioning block, and a linkage block. The first motor is fixedly arranged on the outer wall of the cable storage box. The first lead screw is rotatably arranged on the primary plate. The drive shaft of the first motor is connected to the first lead screw. The secondary plate is threadedly connected to the first lead screw. Two sprockets are symmetrically arranged at both ends of the secondary plate. The chain is jointly sleeved and meshed on the two sprockets. The positioning block is fixedly arranged on the primary plate and is fixed to one side of the chain. The linkage block is fixedly arranged on the tertiary plate and is fixed to the other side of the chain.

[0009] By adopting the above technical solution, after the charging gun is disengaged from the interface, the first motor is used to drive the first lead screw to rotate. The secondary plate is guided to slide along its length direction on the primary plate. While the secondary plate is sliding, since the chain is fixed to the positioning block, the chain is subjected to a tensile force and will drive on the sprockets, thereby driving the sprockets to rotate. While the chain is driving, the linkage block is stressed, driving the tertiary plate to slide along its length direction on the secondary plate. Thus, only by the first motor, it is possible to control the secondary plate to slide on the primary plate while the tertiary plate slides on the secondary plate, effectively expanding the retracting and releasing distance of the charging gun, with convenient control and low implementation cost.

[0010] Preferably, the retracting and releasing assembly includes a worm gear and a worm. The worm is arranged on the first lead screw and coaxially arranged. The worm gear is connected to the end wall of one of the clamping rollers. The worm gear and the clamping roller connected thereto are coaxially arranged. The worm gear penetrates through the cable storage box and meshes with the worm.

[0011] By adopting the above technical solution, when the first motor drives the lead screw to rotate to control the telescopic component to work, the first motor drives the worm to rotate. The worm abuts against the worm wheel, driving one of the clamping rollers to rotate. The clamping roller drives the charging cable to wind and unwind by using friction. In this way, while controlling the telescopic component to work, the clamping roller is automatically driven to rotate, which is convenient to control and saves the device cost.

[0012] Preferably, a guide rod is inclinedly arranged in the cable storage box. A counterweight block is sleeved on the guide rod. A contact wheel is rotatably arranged on the counterweight block. The contact wheel abuts against the charging cable.

[0013] By adopting the above technical solution, when the charging cable is recycled into the cable storage box, the counterweight block drives the contact wheel to abut against the charging cable. Due to the large weight of the counterweight block, under the action of gravity, the counterweight block continuously descends on the guide rod. The counterweight block makes the charging cable arranged in a "V" shape in the cable storage box, automatically and quickly sorting the recycled charging cable, reducing the phenomenon of the charging cable being randomly arranged in the cable storage box, and storing the charging cable in an orderly manner, which is beneficial to further extending the service life of the charging cable.

[0014] Preferably, an oil injection hole is formed on the surface of the counterweight block.

[0015] By adopting the above technical solution, lubricating oil can be injected between the counterweight block and the guide rod through the oil injection hole, reducing the friction between the counterweight block and the guide rod, ensuring that the counterweight block can have a good pressing and sorting effect on the charging cable, and facilitating the maintenance of the equipment.

[0016] Preferably, an installation frame is arranged on the cable storage box. A cross-moving rod is fixedly arranged between the installation frames. The cable storage box is slidably arranged on the cross-moving rod. A sliding component is arranged on the cable storage box. The sliding component is used to drive the cable storage box to slide on the cross-moving rod.

[0017] Preferably, the sliding component includes a second motor and a second lead screw. The second motor is fixedly arranged on the installation frame. The second lead screw is rotatably arranged on the installation frame. The length direction of the second lead screw is parallel to the length direction of the cross-moving rod. The cable storage box is in threaded connection with the second lead screw. The driving shaft of the second motor is connected to the second lead screw.

[0018] By adopting the above technical solution, when the user parks at the charging pile, they may reverse or drive directly into the parking space. By using the second motor to drive the second lead screw to rotate, and the cable storage box is guided by the cross-moving rod, the cable storage box can horizontally slide on the cross-moving rod. By using the sliding component to change the position of the cable storage box on the installation frame, and cooperating with the telescopic component, the displacement position of the charging gun can be further enlarged, which is convenient for charging different models of cars and improves the applicability of the charging pile.

[0019] Preferably, a bearing is provided at one end of the wire storage box facing the cabinet body. The outer ring of the bearing is fixed to the cabinet body, and the charging wire passes through the bearing and is fixed to the inner ring of the bearing. A support cylinder is rotatably provided on the side wall of the wire storage box and above the bearing. The charging wire passes through the support cylinder. A bent rod abutted against the support cylinder is fixedly provided at the top end of the cabinet body, and the middle of the bent rod is high while the two ends are low.

[0020] By adopting the above technical solution, since the connection part between the charging wire and the cabinet body is located at the center of the top end of the cabinet body, when the sliding component drives the wire storage box to horizontally slide on the crosswise rod, the bearing rotates, enabling the charging wire to adapt to different positions on the wire storage box. At the same time, the bent rod abuts against the support cylinder, and the middle of the bent rod is high while the two ends are low. The support cylinder slides on the bent rod. When the wire storage box approaches the middle of the cabinet body, the support cylinder rotates and rises. When the wire storage box approaches the two ends of the cabinet body, the support cylinder rotates and descends, keeping the charging wire between the cabinet body and the wire storage box in a taut state, sorting the charging wire, further protecting the charging wire, reducing the phenomenon of accidental contact of the charging wire, being beneficial to aesthetics, and achieving low cost.

[0021] In summary, the present application includes at least one of the following beneficial technical effects:

[0022] 1. By providing the cabinet body, the wire storage box, the first-level plate, the second-level plate, the third-level plate, the telescopic component, the charging wire, the guide wheel, the charging gun, the interface, the clamping roller and the winding and unwinding component, after the user parks the car beside the cabinet body, first disconnect the charging gun from the interface on the cabinet body, and then control the telescopic component to work. While the telescopic component drives the second-level plate to slide on the first-level plate, the third-level plate slides on the second-level plate. At the same time, the winding and unwinding component drives the clamping roller to rotate, and the clamping roller gradually releases the charging wire in the wire storage box, so that the charging gun can gradually move away from the cabinet body below the guide wheel. When the charging gun moves to the position where charging is required, control the telescopic component to stop working. During the whole process, the charging wire is located on the first-level plate, the second-level plate and the third-level plate, and the charging gun hangs below the guide wheel, avoiding the situation that the charging wire is damaged by friction with the ground, thereby protecting the charging wire and being beneficial to extending the service life of the charging wire;

[0023] 2. By providing the first motor, the first lead screw, the sprocket, the chain, the positioning block and the linkage block, after disconnecting the charging gun from the interface, use the first motor to drive the first lead screw to rotate. The second-level plate is guided and slides on the first-level plate along its length direction. While the second-level plate slides, since the chain is fixed to the positioning block, the chain is subjected to a pulling force and will drive on the sprocket, thereby driving the sprocket to rotate. While the chain drives, the linkage block is stressed and drives the third-level plate to slide on the second-level plate along its length direction. Thus, only by the first motor can the second-level plate be controlled to slide on the first-level plate while the third-level plate slides on the second-level plate, effectively expanding the retracting and extending distance of the charging gun, being convenient to control, and achieving low cost;

[0024] 3. By setting a worm gear, a worm, a guide rod, a configuration block and a contact wheel, when the first motor drives the lead screw to rotate to control the telescopic assembly to work, the first motor drives the worm to rotate. The worm abuts against the worm gear, driving one of the clamping rollers to rotate. The clamping roller drives the charging cable to wind and unwind by using friction. In this way, while controlling the telescopic assembly to work, the clamping roller is automatically driven to rotate. The counterweight drives the contact wheel to abut against the charging cable. Due to the large weight of the counterweight, under the action of gravity, the counterweight continuously descends on the guide rod. The configuration block arranges the charging cable in a "V" shape in the cable storage box, automatically and quickly sorting the recycled charging cable, reducing the phenomenon of the charging cable being randomly arranged in the cable storage box, and storing the charging cable in an orderly manner, which is beneficial to further extending the service life of the charging cable.

Detailed Embodiment

[0030] The following Figures 1-4 further elaborates on the present application in detail.

[0031] An embodiment of the present application discloses a new energy vehicle charging pile. Refer to Figures 1 to 3, which includes a cabinet body 1 for power supply. The cabinet body 1 is fixed on the ground. A wire storage box 11 is arranged on the cabinet body 1, and the wire storage box 11 is used for storing charging cables 3. A first-level plate 21 is fixedly arranged on the side wall of the wire storage box 11. The length direction of the first-level plate 21 is arranged along the width direction of the cabinet body 1. A second-level plate 22 is slidably arranged on the side wall of the first-level plate 21, and a third-level plate 23 is slidably arranged on the side wall of the second-level plate 22. The length directions of the first-level plate 21, the second-level plate 22, and the third-level plate 23 are parallel to each other. A telescopic assembly is arranged on the wire storage box 11. After the first-level plate 21, the second-level plate 22, and the third-level plate 23 are slidably unfolded by using the telescopic assembly, the distance between the end of the third-level plate 23 and the cabinet body 1 will increase. After the first-level plate 21, the second-level plate 22, and the third-level plate 23 are slidably contracted, the first-level plate 21, the second-level plate 22, and the third-level plate 23 will overlap to reduce the occupied space.

[0032] Referring to Figure 1 and Figure 2 , a charging cable 3 is arranged at the top end of the cabinet body 1. The connection position between the charging cable 3 and the cabinet body 1 is located at the middle position of the top end of the cabinet body 1. A guide wheel 231 is rotatably arranged at the end of the third-level plate 23. The charging cable 3 passes through the wire storage box 11 and is wound around the guide wheel 231. A charging gun 31 is arranged at the end of the charging cable 3. An interface 311 for inserting and fixing the charging gun 31 is arranged on the cabinet body 1. When the charging pile is not in use, the charging gun 31 is inserted into the interface 311.

[0033] Referring to Figures 1 to 4 , a group of clamping rollers 4 are symmetrically and rotatably arranged in the wire storage box 11. The surface of the clamping rollers 4 is made of flexible rubber material. The charging cable 3 passes through the two clamping rollers 4, and the clamping rollers 4 are in contact with the charging cable 3. A winding and unwinding assembly is arranged on the wire storage box 11. After the user parks the car beside the cabinet body 1, the user operates through the control panel on the side wall of the cabinet body 1. First, the charging gun 31 is separated from the interface 311 on the cabinet body 1. Then, when the user holds the charging gun 31 with one hand, the user can control the telescopic assembly to work through the mobile phone. While the telescopic assembly drives the second-level plate 22 to slide on the first-level plate 21, the third-level plate 23 slides on the second-level plate 22, so that the first-level plate 21, the second-level plate 22, and the third-level plate 23 are gradually unfolded, driving the guide wheel 231 on the third-level plate 23 to gradually move away from the cabinet body 1. While the telescopic assembly works, the winding and unwinding assembly works, and the winding and unwinding assembly drives the clamping rollers 4 to rotate. The clamping rollers 4 use friction to gradually release the charging cable 3 in the wire storage box 11, so that the charging gun 31 can gradually move away from the cabinet body 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; after charging is completed, the telescopic assembly drives the first-level plate 21, the second-level plate 22, and the third-level plate 23 to retract, and at the same time the winding and unwinding assembly recovers the charging cable 3 into the wire storage box 11. During the whole process, the charging cable 3 is located on the first-level plate 21, the second-level plate 22, and the third-level plate 23, and the charging gun 31 hangs under the guide wheel 231 for use, avoiding the situation that the charging cable 3 is damaged by friction with the ground.

[0034] Referring to Figure 3 Figure 3 , the telescopic assembly includes a first motor 51, a first lead screw 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 lead screw 52 is rotatably arranged on the first-stage plate 21. The length direction of the first lead screw 52 is arranged along the length direction of the first-stage plate 21. The drive shaft of the first motor 51 is connected to the first lead screw 52. The second-stage plate 22 is threadedly connected to the first lead screw 52. Two sprockets 53 are symmetrically and rotatably arranged at both ends of the second-stage plate 22. The chain 54 is jointly sleeved and meshed on the two sprockets 53. The positioning block 55 is fixedly arranged at one end of the first-stage plate 21 away from the cabinet body 1. The positioning block 55 is fixedly connected to one side of the chain 54. The linkage block 56 is fixedly arranged at one end of the third-stage plate 23 close to the cabinet body 1. The linkage block 56 is fixedly connected to the other side of the chain 54. The positioning block 55 is located above the linkage block 56. After the charging gun 31 is separated from the interface 311, the user controls the first motor 51 to work. The first motor 51 drives the first lead screw 52 to rotate. The second-stage plate 22 is guided to slide along its length direction on the first-stage plate 21. While the second-stage plate 22 slides, since the chain 54 is fixed to the positioning block 55, the chain 54 is subjected to a pulling force and will drive on the sprocket 53, thereby driving the sprocket 53 to rotate. While the chain 54 drives, the linkage block 56 is stressed and drives the third-stage plate 23 to slide along its length direction on the second-stage plate 22. Thus, only by the first motor 51, it is possible to control the second-stage plate 22 to slide on the first-stage plate 21 while the third-stage plate 23 slides on the second-stage plate 22, effectively expanding the retracting and extending distance of the charging gun 31, with convenient and fast control and effective utilization of space.

[0035] Referring to Figure 3 and Figure 4 Figure 4 , the retracting and extending assembly includes a worm gear 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 lead screw 52 and coaxially arranged. The worm 62 and the first lead screw 52 are coaxially arranged. The worm gear 61 is connected to the end wall of one of the clamping rollers 4. The worm gear 61 and the clamping roller 4 connected thereto are coaxially arranged. The worm gear 61 penetrates through the wire storage box 11 and meshes with the worm 62. When the first motor 51 drives the lead screw to rotate to control the telescopic assembly to work, the first motor 51 drives the worm 62 to rotate. The worm 62 abuts against the worm gear 61 and drives one of the clamping rollers 4 to rotate. The clamping roller 4 drives the charging wire 3 to retract and extend by means of friction. In this way, while controlling the telescopic assembly to work, the clamping roller 4 is automatically driven to rotate, achieving synchronous work and saving the device cost.

[0036] Referring to Figure 4, a guide rod 7 is inclined in the wire storage box 11. The highest end of the guide rod 7 is close to the clamping roller 4. A counterweight block 71 is sleeved on the guide rod 7. An oil injection hole 711 is formed on the surface of the counterweight block 71. The configuration block can slide on the guide rod 7 along the length direction of the guide rod 7. A contact wheel 72 is rotatably arranged on the counterweight block 71, and the contact wheel 72 abuts against the charging cable 3. When the charging cable 3 is retracted into the wire storage box 11, the counterweight block 71 drives the contact wheel 72 to abut against the charging cable 3. Due to the large weight of the counterweight block 71, under the action of gravity, the counterweight block 71 continuously descends on the guide rod 7. The configuration block arranges the charging cable 3 in a "V" shape in the wire storage box 11, automatically and quickly sorting the retracted charging cable 3, reducing the phenomenon of the charging cable 3 being randomly arranged in the wire storage box 11, and storing the charging cable 3 in an orderly manner, which is beneficial to further extending the service life of the charging cable 3.

[0037] Refer to Figure 1 , an installation frame 8 is arranged on the wire storage box 11. A cross-moving rod 81 is fixedly arranged between the installation frames 8. The length direction of the cross-moving rod 81 is arranged along the length direction of the installation frame 8. The wire storage box 11 is slidably arranged on the cross-moving rod 81. A sliding component is arranged on the wire storage box 11. The sliding component includes a second motor 91 and a second lead screw 92. The second motor 91 is fixedly arranged on the installation frame 8. The second lead screw 92 is rotatably arranged on the installation frame 8. The length direction of the second lead screw 92 is parallel to that of the cross-moving rod 81. The wire storage box 11 is threadedly connected to the second lead screw 92, and the drive shaft of the second motor 91 is connected to the second lead screw 92. When the user parks at the charging pile, they may reverse or drive directly into the parking space. Therefore, the position for connecting to the vehicle charging is not necessarily fixed. By driving the second lead screw 92 to rotate with the second motor 91, the wire storage box 11 is guided by the cross-moving rod 81, and the wire storage box 11 can horizontally slide on the cross-moving rod 81. By using the sliding component to change the position of the wire storage box 11 on the installation frame 8, and cooperating with the telescopic component, the displacement position of the charging gun 31 can be further expanded, which is convenient for charging different models of vehicles and improves the applicability of the charging pile.

[0038] Refer to Figure 1 and Figure 4, one end of the wire storage box 11 facing the cabinet body 1 is provided with a bearing 111. The outer ring of the bearing 111 is fixedly welded to the cabinet body 1. The charging wire 3 passes through the bearing 111, and the charging wire 3 is fixedly bonded to the inner ring of the bearing 111. A support cylinder 12 is rotatably arranged on the side wall of the wire storage box 11 above the bearing 111 through a hinge. The support cylinder 12 can rotate away from the cabinet body 1, and the charging wire 3 passes through the support cylinder 12. A bending rod 10 that abuts against the lower end of the support cylinder 12 is fixedly arranged at the top end of the cabinet body 1. The length direction of the bending rod 10 is arranged along the width direction of the cabinet body 1, and the bending rod 10 is set with a higher middle and lower ends. Since the connection part of the charging wire 3 and the cabinet body 1 is located at the center of the top end of the cabinet body 1, when the sliding component drives the wire storage box 11 to horizontally slide on the transverse moving rod 81, the bearing 111 rotates, enabling the charging wire 3 to adapt to different positions on the wire storage box 11. At the same time, the bending rod 10 abuts against the support cylinder 12, and the support cylinder 12 slides on the bending rod 10. When the wire storage box 11 approaches the middle of the cabinet body 1, the support cylinder 12 rotates and rises. When the wire storage box 11 approaches both ends of the cabinet body 1, the support cylinder 12 rotates and descends, keeping the charging wire 3 between the cabinet body 1 and the wire storage box 11 in a taut state, sorting the charging wire 3, further protecting the charging wire 3, reducing the phenomenon of accidental contact of the charging wire 3, being beneficial to aesthetics at the same time, and achieving low cost.

[0039] The implementation principle of a new energy vehicle charging pile in an embodiment of this application is as follows: After the user parks the electric vehicle beside the cabinet 1, the user operates using the control panel on the side wall of the cabinet 1. First, the charging gun 31 is detached from the interface 311 on the cabinet 1. The user controls the operation of the first motor 51 by scanning the code with the mobile phone. One hand holds the charging gun 31 and the other hand controls the operation of the first motor 51 through the mobile phone. The first motor 51 drives the first lead screw 52 to rotate, controls the secondary plate 22 to slide on the primary plate 21. The chain 54 is subjected to a tensile force, and the chain 54 will drive on the sprocket 53, thereby driving the sprocket 53 to rotate. While the chain is driving, the linkage block 56 is stressed, driving the tertiary plate 23 to slide along its length direction on the secondary plate 22, 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 gear 61, controls one of the clamping rollers 4 to rotate, and the clamping roller 4 uses friction to gradually release the charging cable 3 in the cable 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 vehicle. After charging is completed, the telescopic assembly drives the primary plate 21, the secondary plate 22, and the tertiary plate 23 to retract. At the same time, the cable winding and unwinding assembly retracts the charging cable 3 into the cable storage box 11. During the whole process, the charging cable 3 is located on the primary plate 21, the secondary plate 22, and the tertiary plate 23, and the charging gun 31 hangs under the guide wheel 231 for use, avoiding the situation that the charging cable 3 is damaged by friction with the ground, effectively extending the service life of the charging cable 3. At the same time, the device has a low implementation cost, convenient and fast control, a wide range of applications, and can adapt to different charging scenarios.

[0040] The above are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
