Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular to a new energy vehicle charging pile. Background Art

[0002] The working principle of pure electric vehicles and plug-in hybrid vehicles mainly relies on electric drive. Their core components include motors and battery packs, so battery packs are extremely important components in new energy vehicles. The battery packs need to be charged by charging piles. 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. A cable is installed between the charging plug and the charging pile. When the charging pile is in use, the new energy vehicle needs to unplug the charging gun from the charging pile and cause the cable to rub against the ground. Most of the time, the cables are placed on the ground at random, causing the cables to age and be damaged after rubbing against the ground for a long time. At the same time, the cables dragged on the ground will be crushed by the reversing vehicle entering the charging station, causing the cables to break. Cable breakage will lead to The leakage phenomenon is very likely to cause safety hazards, so the patent application with patent publication number CN117162836B provides a new energy vehicle intelligent charging pile. By starting the motor in the charging pile body, the output end of the motor starts to rotate with the reel, and the reel drives the charging cable to start recycling, thereby well protecting the charging cable and the charging pile body. Of course, the charging pile generally provides two charging methods: conventional charging and fast charging. For fast charging piles, their power is much greater than that of conventional charging piles, which makes conventional cables unable to withstand it. Therefore, the cable connected to the fast charging pile will be thicker. For this type of cable, curling will occur when it is wound, and long-term curling will seriously affect the service life of the cable, resulting in increased subsequent maintenance costs of the new energy vehicle charging pile.

[0003] Therefore, a new energy vehicle charging pile is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a new energy vehicle charging pile to solve the problem that the long-term curling of the cable of a conventional charging pile will seriously affect the service life of the cable and increase the subsequent maintenance cost of the new energy vehicle charging pile.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A new energy vehicle charging pile includes a charging pile shell, a cable is fixedly installed on one side of the charging pile shell, one end of the cable is connected to an electrical component in the charging pile shell, and a charging gun is fixedly installed on the other end of the cable. A plurality of protective covers are provided on the cable, and both ends of the protective covers are provided with rounded corners. The plurality of protective covers are evenly distributed on the cable. A pulling assembly for pulling the plurality of protective covers to move is installed on the charging pile shell, and the plurality of protective covers are divided into multiple groups, and a deflection piece is provided between each two adjacent groups of protective covers.

[0007] After the vehicle leaves, the pulling component is operated, and the pulling component pulls multiple protective covers together, so that the cable bent and placed on the parking space can swing to one side and move to one side of the charging pile, to avoid the cable remaining in the parking space and causing the next car ready to charge to collide and squeeze it. Therefore, the cable is straightened by the pulling component to keep it away from the parking space to avoid the cable being squeezed by the vehicle and causing the cable to break, and to avoid long-term curling and metal fatigue, thereby ensuring the later maintenance cost of the new energy vehicle charging pile. At the same time, the deflection part deflects the connection direction of the two adjacent sets of protective covers, so that the straight cable pulled to one side by the pulling component is bent, reducing the space occupied by the cable and reducing the space occupied by the new energy vehicle charging pile when in use.

[0008] Preferably, the pulling assembly includes a winch, a drive motor, a steel wire rope, and a round block. The capstan is rotatably connected in the charging pile shell, and the drive motor is fixedly installed in the charging pile shell. The output shaft of the drive motor is fixedly installed on the winch. A steel wire rope is wound on the winch, and the steel wire rope is provided with two strands. Two symmetrical through holes are provided on the protective cover, and the two strands of the steel wire rope pass through the through holes. One end of the steel wire rope close to the charging gun is fixedly installed on the protective cover. After the protective cover is closed, a reference plane is formed between the two strands of the steel wire rope and is perpendicular to the ground. The other end of the steel wire rope is fixedly installed on the protective cover on the side away from the charging pile shell. A round block is fixedly installed on the steel wire rope, and an abutment is provided in the protective cover. When the steel wire rope pulls the round block to move, the round block abuts against the abutment, and the abutment pushes the multiple protective covers to move.

[0009] The steel wire rope fixed on it is wound by the forward rotation of the winch, so that the steel wire rope is continuously wrapped around it. Because the steel wire rope is stretched into the charging pile in large quantities, multiple protective covers will continue to move closer to the charging pile, so that the protective covers are close together to form a straight protection channel on one side to protect the cable in the middle. At the same time, the straight protection channel will be close to the side wall of the charging pile, so that the cable will also be placed straight on one side of the charging pile moved under the guidance of the protective cover. The cable is straightened by pulling the steel wire rope to move it away from the parking space to avoid the cable being squeezed by the vehicle and causing the cable to break, thereby ensuring the later maintenance cost of the new energy vehicle charging pile.

[0010] Preferably, the deflection member includes a first guide sleeve, a second guide sleeve, a limit bar, a fixed block, and a cylinder. A first guide sleeve and a second guide sleeve are provided in the middle of the two groups of protective sleeves. The first guide sleeve is fixedly installed on the protective sleeve on one side, and the second guide sleeve is fixedly installed on the protective sleeve on the other side. When the first guide sleeve and the second guide sleeve are closed, the bent cable forms a 160° angle. A plurality of fixed blocks are fixedly installed on the first guide sleeve, and a limit bar is rotatably installed on the fixed block. A limit slot is provided on the second guide sleeve, and the limit bar is slidably connected in the limit slot. Cylinders are slidably connected to the side walls on both sides of the limit slot, and one end of the cylinder is fixedly installed to the limit bar. When the first guide sleeve and the second guide sleeve are closed together, the limit bar and the fixed block enter the limit slot.

[0011] When the steel wire rope pulls the protective sleeve to move to one side, the protective sleeve pushes the first guide sleeve to move to one side, and the moving first guide sleeve pushes the limit bar to continuously enter the limit groove. After a period of time, the parallel surfaces on the first guide sleeve and the second guide sleeve abut against each other, so that the first guide sleeve and the second guide sleeve are inclined to each other. At the same time, the limit bar and the fixed block will also enter the limit groove. The inclined setting of the first guide sleeve and the second guide sleeve will also cause the cable sleeved therein to be bent, and the space occupied by the cable is reduced by bending back and forth. At the same time, after the steel wire rope pulls the cable to move to the specified position, the steel wire rope is relaxed to release the torque generated when the cable is bent, thereby preventing the cable from being damaged due to long-term stress and bending, thereby ensuring the later maintenance cost of the new energy vehicle charging pile.

[0012] Preferably, a plurality of grooves are provided on the outer wall of the protective sleeve, and the plurality of grooves are distributed in a ring shape on the side wall of the protective sleeve. Steel balls are rollingly connected in the grooves, and two-thirds of the volume of the steel balls enters the grooves. A plurality of silicone rings are fixedly installed on the protective sleeve, and the silicone rings are arranged on the outside of the grooves, and the silicone rings abut against the surface of the steel balls.

[0013] By installing multiple balls on the outer wall of the protective cover, the protective cover can be easily moved on the ground. At the same time, two-thirds of the volume of the steel balls enters the groove, so that the steel balls will always be placed in the groove and will not fall off. Of course, because the steel balls will roll on the ground for a long time, dirt will adhere to the balls. The silicone ring set on the outside of the groove can scrape off the dirt on the balls to prevent it from affecting the normal operation of the balls.

[0014] Preferably, the abutment includes a pushing column, a lifting plate, a first compression spring, a locking column, and a locking block, the protective cover is provided with a mounting groove connected to the through hole, the mounting groove is slidably connected to the pushing column, one end of the pushing column is fixedly installed with a lifting plate, the mounting groove is provided with a first compression spring, the first compression spring is sleeved on the pushing column, one end of the first compression spring abuts against the inner wall of the mounting groove, and the other end abuts against the lifting plate, a locking column is fixedly installed on one side of the lifting plate, and when the steel wire rope pulls the round block to move, the round block abuts against the pushing column, and a locking block is fixedly installed on one end of the protective cover, and a locking groove cooperating with the locking column is provided on the locking block. After unfolding, the distance between two adjacent protective covers in each group is different, and the distance between the protective covers away from the charging pile shell gradually increases.

[0015] The steel wire rope will drive the round block fixed on it to move at the same time. Because the round block is in contact with the pushing column, the round block can drive the pushing column to move at the same time when it moves, and of course it also drives the protective cover to move, so that each protective cover can be stressed and moved to the specified position. Because each protective cover needs to be pushed to move each section of the steel wire to avoid local stress concentration of the steel wire rope, reduce wear and fatigue damage, thereby extending the service life of the steel wire rope and evenly stressing it. Of course, after the protective cover on one side is driven by the round block to move to the specified position, the locking column in the installation groove is pushed into the locking groove of the locking block. At this time, multiple locking columns are pushed into the locking groove, so that each protective cover can be stressed at the same time and moved to the specified position, and each group of two adjacent protective covers The distances between the protective covers are different. The closer the protective covers are to the outer shell of the charging pile, the smaller the distance between them is. The protective covers close to the outer shell of the charging pile are closed first, so that the subsequent protective covers can be closed in sequence. Closing in sequence can gradually fix the various parts of the protective covers. Because the steel wire rope cannot ensure that the protective covers are in the specified position after pulling multiple protective covers together, the protective cover fixed on the outer shell of the charging pile needs to be connected to the adjacent protective cover to ensure the position of the cable after closing. Pulling the entire cable and the connected protective cover to move the whole requires not only great pulling force, but also the last two protective covers can easily fail to be pulled and misaligned when closing, resulting in the cable being unable to move to the specified position, so that the protective cover can protect the cable stably for a long time.

[0016] Preferably, a linear protrusion is fixedly mounted on the outer sheath of the cable. The protrusion is made of the same material as the outer sheath of the cable. The protrusion is arranged along the length direction of the cable, and the protective cover is provided with a long through groove for the line to pass through.

[0017] During the closing process of the protective cover, the cable can be driven to flip over, and the cable that has been rotated a small number of times can be twisted back to its original position, thereby avoiding damage to the cable caused by long-term twisting, further improving the protection of the cable and preventing damage to the cable.

[0018] Preferably, a semicircular groove is provided on one side of the protective cover, a deep groove is provided on the top of the semicircular groove, an arc-shaped plate is slidably connected in the semicircular groove, and the arc-shaped plate can move forward, backward, left and right in the semicircular groove, a second compression spring is placed in the semicircular groove to abut against the arc-shaped plate, a short column is fixedly installed on the arc-shaped plate, a strip plate is fixedly installed on one side of the semicircular groove, a short groove is provided on the other side of the protective cover, and one end of the arc-shaped plate is hinged in the short groove.

[0019] The two protective covers are connected to each other through the arc plate, and at the same time, one side of the arc plate slides in the deep groove through a short column, so that one side of the arc plate can be universally adjusted to a certain angle, and at the same time, the other side of the arc plate is hinged in the short groove through a hinge column, so the other side of the arc plate can be universally adjusted relative to the protective cover on the other side. Of course, because the protective covers on both sides can be retracted together, the arc plate can enter the semicircular groove and the deep groove, so that the protective covers on both sides can be close together. The arc plate can make the protective cover flipped at a certain angle, but it cannot rotate indefinitely, so as to avoid the cables twisting and entangled due to long-term use, and prevent the twisted cables from being unable to move through the protective cover and being crushed by the vehicle, thereby indirectly ensuring the later maintenance cost of the new energy vehicle charging pile.

[0020] Preferably, a support frame is fixedly installed on the cable, a sliding plate is slidably connected to the support frame, one side of the sliding plate is fixedly installed with the wire rope, and a third compression spring is fixedly installed between the other side of the sliding plate and the support frame. By using the third compression spring, the protective cover close to the gun head can return to its original position faster than other protective covers, so that the charging gun head can quickly put into use.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. After the vehicle leaves, the pulling component is operated. The pulling component pulls multiple protective covers together through steel wire ropes, so that the cables bent and placed on the parking space can swing to one side and move to the side of the charging pile to avoid the cables being squeezed by the vehicle and broken during the movement. At the same time, because the cables are dragged to one side of the charging pile, the need for winding during recycling is avoided, so that the cables can be avoided from being wound while being recycled and sorted, thereby reducing the later maintenance costs of the new energy vehicle charging pile.

[0023] 2. After the round block drives the protective cover on one side to move to the specified position, the locking column in the installation groove will be pushed into the locking groove of the locking block, so that each protective cover can be stressed and moved to the specified position. Because each section of the steel wire needs to exert force when pushing each protective cover to move, the steel wire rope can be evenly stressed, which increases the service life of the steel wire rope and reduces the tension required to pull the steel wire rope. By ensuring the service life of the steel wire rope, the cable is indirectly protected, and the later maintenance cost of the new energy vehicle charging pile is reduced.

[0024] 3. The inclined setting of the first guide sleeve and the second guide sleeve allows the cable sleeved therein to be bent, and the space occupied by the cable is reduced by bending back and forth. Of course, because the bending position is only where the direction changes, the wire rope is released after bending, avoiding damage caused by the wire rope pulling the cable for a long time, thereby ensuring the later maintenance cost of the new energy vehicle charging pile.

[0034] See also Figures 1 to 8 The present invention provides a new energy vehicle charging pile, and the technical solution is as follows:

[0035] A new energy vehicle charging pile includes a charging pile shell 1, a cable 2 is fixedly installed on one side of the charging pile shell 1, one end of the cable 2 is connected to the electrical components in the charging pile shell 1, and a charging gun 3 is fixedly installed on the other end of the cable 2. It is characterized in that a plurality of protective covers 4 are provided on the cable 2, both ends of the protective covers 4 are provided with rounded corners, and the plurality of protective covers 4 are evenly distributed on the cable 2. A pulling component for pulling the plurality of protective covers 4 to move is installed on the charging pile shell 1, and the plurality of protective covers 4 are divided into multiple groups, and a deflection piece is provided between each two adjacent groups of protective covers 4.

[0036] When charging, the vehicle is parked in the parking space corresponding to the new energy vehicle charging pile, the charging gun 3 is removed from the charging pile, and it is inserted into the charging port of the vehicle. After a period of time, the charging gun 3 is inserted into the charging pile shell 1 before the vehicle leaves. After the vehicle leaves, the pulling component is operated, and the pulling component pulls multiple protective covers 4 together, so that the cable 2 bent and placed on the parking space can swing to one side and move to one side of the charging pile to avoid the cable 2 remaining in the parking space and causing the next car to be charged to collide and squeeze it. Therefore, the cable 2 is straightened by the pulling component to keep it away from the parking space to avoid the cable 2 being squeezed by the vehicle and causing the cable to break, and to avoid its long-term curling and metal fatigue, thereby ensuring the later maintenance cost of the new energy vehicle charging pile. At the same time, the deflection member deflects the connection direction of the two adjacent sets of protective covers 4, so that the straight cable pulled to one side by the pulling component is bent, reducing the space occupied by the cable and reducing the space occupied by the new energy vehicle charging pile when in use.

[0037] The pulling assembly includes a winch 5, a drive motor 6, a wire rope 15, and a round block 29. The winch 5 is rotatably connected in the charging pile shell 1, and the drive motor 6 is fixedly installed in the charging pile shell 1. The output shaft of the drive motor 6 is fixedly installed on the winch 5. The wire rope 15 is wound on the winch 5. The wire rope 15 has two strands. The protective cover 4 has two symmetrical through holes 31. The two strands of wire rope 15 pass through the through holes 31. One end of the wire rope 15 close to the charging gun 3 is fixed to the protective cover 4. After the protective cover 4 is closed, a reference plane is formed between the two strands of wire rope 15 and is perpendicular to the ground. The other end of the wire rope 15 is fixed to the protective cover 4 on the side away from the charging pile shell 1. A round block 29 is fixedly installed on the wire rope 15, and an abutment is provided in the protective cover 4. When the wire rope 15 pulls the round block 29 to move, the round block 29 abuts against the abutment and pushes multiple protective covers 4 to move through the abutment.

[0038] The pulling assembly pulls the cable 2 to one side and swings it back to the side of the charging pile to wait for use, so as to avoid damage to the cable 2 caused by the vehicle driving on it. When it is used specifically, the driving motor 6 in the charging pile starts to operate after the vehicle leaves, and the output shaft of the driving motor 6 drives the winch 5 to rotate forward, and the steel wire rope 15 fixed thereon is wound around it through the forward rotation of the winch 5, so that the steel wire rope 15 is continuously wound around it. Because the steel wire rope 15 is stretched into the charging pile in large quantities, the multiple protective covers 4 will continuously move closer to the charging pile, so that the protective covers 4 are close together to form a straight protection channel on one side, which is used for the cable 2 in the middle. The protective cover 4 is provided to protect the charging pile, and a straight protective channel is formed to close to the side wall of the charging pile, so that the cable 2 is also moved under the guidance of the protective cover 4 and placed straight on one side of the charging pile. Of course, the reference plane formed between the two steel wire ropes 15 is perpendicular to the ground. This is to ensure that when the cable 2 is subsequently bent and placed, the two steel wires pull the protective cover 4 to move at the same length, so as to avoid the steel wire ropes 15 on both sides moving at different speeds when the cable 2 is bent and placed. The cable 2 is straightened by pulling the steel wire rope 15 to keep it away from the parking space, so as to avoid the cable 2 being squeezed by the vehicle and causing the cable to break, thereby ensuring the later maintenance cost of the new energy vehicle charging pile.

[0039] The deflection member includes a first guide sleeve 7, a second guide sleeve 8, a limit strip 13, a fixed block 12, and a cylinder 36. A first guide sleeve 7 and a second guide sleeve 8 are provided in the middle of the two groups of protective sleeves 4. The first guide sleeve 7 is fixedly installed on one side of the protective sleeve 4, and the second guide sleeve 8 is fixedly installed on the other side of the protective sleeve 4. When the first guide sleeve 7 and the second guide sleeve 8 are closed, the bent cable 2 forms a 160° angle. A plurality of fixed blocks 12 are fixedly installed on the first guide sleeve 7, and the limit strip 13 is rotatably installed on the fixed block 12. A limit groove 14 is provided on the second guide sleeve 8, and the limit strip 13 is slidably connected in the limit groove 14. Cylinders 36 are slidably connected on the side walls on both sides of the limit groove 14. One end of the cylinder 36 is fixedly installed with the limit strip 13. When the first guide sleeve 7 and the second guide sleeve 8 are closed together, the limit strip 13 and the fixed block 12 enter the limit groove 14.

[0040] It should be noted that, because the straight protective channel will be close to the side wall of the charging pile, the cable 2 will also be moved to one side of the charging pile under the guidance of the protective sleeve 4 and placed straight. At the same time, the length of the cable 2 is fixed, and once the cable 2 is swung straight to one side of the charging pile, the space occupied will be very large, resulting in a reduction in the space utilization rate of the charging pile. Therefore, it is necessary to reduce the overall length of the cable 2 after it is straightened to avoid the cable 2 occupying too much space. Specifically, when the wire rope 15 pulls the protective sleeve 4 to move to one side, the protective sleeve 4 pushes the first guide sleeve 7 to move to one side, and the moving first guide sleeve 7 pushes the limit bar 13 to continuously enter the limit groove 14. After a period of time, the approaching surfaces on the first guide sleeve 7 and the second guide sleeve 8 abut against each other, so that the first guide sleeve 7 and the second guide sleeve 8 are inclined to each other. At the same time, the limit bar 13 and the fixed block 12 will also enter the limit groove 14, through the inclination of the first guide sleeve 7 and the second guide sleeve 8. The oblique setting causes the cable 2 sheathed therein to be bent as well, and the space occupied by the cable 2 is reduced by bending back and forth. At the same time, after the steel wire rope 15 pulls the cable 2 to move to the specified position, the steel wire rope 15 is relaxed, releasing the torque generated when pulling the cable 2 to bend, thereby preventing the cable 2 from being damaged due to long-term stress and bending, and ensuring the later maintenance cost of the new energy vehicle charging pile. Under normal circumstances, the bending angle of the cable should not be too large. The specific restrictions vary depending on the type and purpose of the cable, but generally speaking, in order to ensure the structural integrity and performance stability of the cable, the bending angle should be avoided as much as possible to exceed 90 degrees. In the present invention, the bending angle formed by the cable is 160°. When the bending angle is less than 160°, the cable will be subjected to excessive bending stress, thereby damaging the cable structure. When it is greater than 180°, the cable will form a straight line. The inability to bend will cause the overall space occupied by the cable to be unable to be reduced, that is, the space occupied by the charging pile installation becomes larger.

[0041] There are multiple grooves on the outer wall of the protective cover 4, and the multiple grooves are distributed in a ring shape on the side wall of the protective cover 4. Steel balls 26 are rollingly connected in the grooves, and two-thirds of the volume of the steel balls 26 enters the grooves. Multiple silicone rings 27 are fixedly installed on the protective cover 4. The silicone rings 27 are arranged on the outside of the grooves, and the silicone rings 27 abut against the surface of the steel balls 26.

[0042] Because the cable 2 will also be moved to one side of the charging pile for placement under the guidance of the protective cover 4, the steel wire rope 15 will exert a greater force to pull the cable 2 as a whole to move. At the same time, the friction generated between the protective cover 4 and the ground will also cause wear on the protective cover 4. Long-term wear will make the protective cover 4 unusable, so by installing multiple balls on the outer wall of the protective cover 4, the protective cover 4 can be easily moved on the ground. At the same time, two-thirds of the volume of the steel ball 26 enters the groove, so that the steel ball 26 will always be placed in the groove without falling. Of course, because the steel ball 26 will roll on the ground for a long time, dirt will adhere to the ball, and the silicone ring 27 set on the outside of the groove can scrape off the dirt on the ball to prevent it from affecting the normal operation of the ball.

[0043] When the locking plate 35 is unlocked, the locking post 33 is locked and the locking block 33 is unlocked, and the locking block 33 is unlocked, so that the locking block 33 can be unlocked.

[0044] It should be noted that under normal conditions, the movement order of the steel wire rope 15 protective cover 4 needs to make the protective cover 4 closest to the farthest end of the gun head move first, and the subsequent multiple protective covers 4 are pulled and dragged together by the first protective cover 4, so that the pulling force when the cable 2 pulls the protective cover 4 together is uneven, and a great pulling force is required to drag the protective cover 4 together. Long-term frequent uneven pulling will seriously affect the overall quality of the protective cover 4. Therefore, when the winch 5 pulls the steel wire rope 15 to move, the steel wire rope 15 will drive the protective cover fixed on it. The round block 29 moves at the same time. Because the round block 29 abuts against the push column 30, the round block 29 can drive the push column 30 to move at the same time when it moves, and of course it drives the protective cover 4 to move, so that each protective cover 4 can be stressed and moved to the specified position. Because each section of the wire rope 15 is required to exert force when pushing each protective cover 4 to move, it avoids local stress concentration of the wire rope 15, reduces wear and fatigue damage, and thus extends the service life of the wire rope 15. Of course, the uniform force is exerted because the protective cover on one side is driven by the round block 29. After the sleeve 4 moves to the designated position, the locking column 33 in the installation groove 28 is pushed into the locking groove 34 of the locking block 16. At this time, multiple locking columns 33 are pushed into the locking groove 34, so that each protective sleeve 4 can be forced at the same time and moved to the designated position. The distance between two adjacent protective sleeves 4 in each group is different. The closer the protective sleeves 4 are to the charging pile shell 1, the smaller the distance between them. The protective sleeves 4 close to the charging pile shell 1 are closed first, so that the subsequent protective sleeves 4 can be closed in sequence. Closing in sequence can gradually fix each protective sleeve 4. Partly, because the steel wire rope 15 cannot ensure that the protective covers 4 are in the specified position after pulling the multiple protective covers 4 together, the protective covers 4 fixed on the charging pile housing 1 need to be connected with the adjacent protective covers 4 to ensure the position of the cable 2 after closing. Pulling the entire cable 2 and the connected protective covers 4 as a whole to move not only requires a huge pulling force, but also the last two protective covers 4 are easily unable to be pulled and misaligned and unable to be closed together when closing, resulting in the cable 2 being unable to move to the specified position, so that the protective cover 4 can protect the cable 2 for a long time.

[0045] A linear protrusion 19 is fixedly mounted on the outer skin of the cable 2. The protrusion 19 is made of the same material as the outer skin of the cable 2 and is arranged along the length direction of the cable 2. The protective cover 4 is provided with a long through groove 20 for the line to pass through.

[0046] By providing linear protrusions 19, the cross-sectional direction of the cable 2 and the relative position of the protective cover 4 are kept fixed, so that when the cable 2 rotates, it can drive the following protective cover 4 to rotate at the same time, so that after the protective covers 4 are separated, a gap can be generated between the two protective covers 4, and the cable 2 and the protrusions 19 thereon can be twisted through the gap. When the protective covers 4 are close to each other, the protrusions 19 and the surface of the cable 2 will fully abut against the protective cover 4. The mutual closing of the protective covers 4 will make the cable 2 unable to move through the gap, and the mutual closing of the protective covers 4 will twist the cable 2 that has rotated a small number of circles back to its original position, avoiding long-term twisting of the cable 2 and causing damage to the cable 2, further improving the protection of the cable 2 and preventing the cable 2 from being damaged.

[0047] A semicircular groove 22 is provided on one side of the protective cover 4, and a deep groove 21 is provided on the top of the semicircular groove 22. An arc-shaped plate 17 is slidably connected to the semicircular groove 22, and the arc-shaped plate 17 can move forward, backward, left and right in the semicircular groove 22. A second compression spring 25 is placed in the semicircular groove 22 to abut against the arc-shaped plate 17. A short column 23 is fixedly mounted on the arc-shaped plate 17. A strip plate 24 is fixedly mounted on one side of the semicircular groove 22. A short groove 18 is provided on the other side of the protective cover 4, and one end of the arc-shaped plate 17 is hinged in the short groove 18.

[0048] When the charging personnel use the cable to charge, they will constantly pull and rotate the cable 2, causing the cable 2 to rotate and tangle multiple times after long-term use, making it impossible for the wire rope 15 to be pulled and causing damage to the cable 2. Therefore, the two protective covers 4 are connected to each other through the arc plate 17. At the same time, one side of the arc plate 17 slides in the deep groove 21 through the short column 23, so that one side of the arc plate 17 can be universally adjusted to a certain angle. At the same time, the other side of the arc plate 17 is hinged in the short groove 18 through the intersection column, so the other side of the arc plate 17 is relatively stable. The protective cover 4 on the other side can be universally adjusted. Of course, because the protective covers 4 on both sides can be retracted together, the arc plate 17 can enter the semicircular groove 22 and the deep groove 21, so that the protective covers 4 on both sides can be close together. The arc plate 17 can make the protective cover 4 flip over at a certain angle, but it cannot rotate without restriction, so as to prevent the cables 2 from twisting and entangled due to long-term use, and prevent the twisted cables 2 from being unable to move through the protective cover 4 and being crushed by the vehicle, thereby indirectly ensuring the later maintenance cost of the new energy vehicle charging pile.

[0049] A support frame 9 is fixedly installed on the cable 2 , and a sliding plate 10 is slidably connected to the support frame 9 . One side of the sliding plate 10 is fixedly installed with the wire rope 15 , and a third compression spring 11 is fixedly installed between the other side of the sliding plate 10 and the support frame 9 .

[0050] Because the protective covers 4 are pulled to a position close to each other and the protective cover 4 close to the gun head needs to be able to return to its original position quickly after the wire rope 15 is loosened, it is necessary to use the third compression spring 11 to allow the protective cover 4 close to the gun head to return to its original position faster than other protective covers 4, so that the charging gun 3 can be quickly put into use.

[0051] During use, after the new energy vehicle is fully charged, the charging gun 3 is inserted into the charging pile housing 1, and the vehicle is driven out of the parking space. After the vehicle is driven out, the component is pulled to run, and the drive motor 6 in the charging pile is operated. The output shaft of the drive motor 6 drives the winch 5 to rotate forward, and the steel wire rope 15 fixed thereon is wound through the forward rotation of the winch 5, so that the steel wire rope 15 is continuously wound thereon. Because the steel wire rope 15 is stretched into the charging pile in large quantities, the multiple protective covers 4 will continue to move closer to the charging pile.

[0052] The steel wire rope 15 will drive the round block 29 fixed thereon to move at the same time. Because the round block 29 abuts against the pushing post 30, the round block 29 can drive the pushing post 30 to move at the same time when it moves, and of course it also drives the protective cover 4 to move, so that the multiple protective covers 4 can be evenly stressed and quickly closed together. Of course, because after the round block 29 drives the protective cover 4 on one side to move to the specified position, the locking post 33 in the installation groove 28 is pushed into the locking groove 34 of the locking block 16. At this time, multiple locking posts 33 are pushed into the locking groove 34, so that each protective cover 4 can be stressed at the same time and moved to the specified position, and the distance between each group of adjacent two protective covers 4 is different. The closer the distance between the protective covers 4 is to the charging pile housing 1, the smaller the distance between them, so that the protective covers 4 close to the charging pile housing 1 are closed first, so that the subsequent protective covers 4 can be closed in turn, making it more convenient for the protective covers 4 to close and push the cable 2 to move to the specified position.

[0053] The friction generated between the protective cover 4 and the ground will also cause wear on the protective cover 4. Long-term wear will make the protective cover 4 unusable. Therefore, by installing multiple balls on the outer wall of the protective cover 4, the protective cover 4 can be easily moved on the ground. At the same time, two-thirds of the volume of the steel ball 26 enters the groove, so that the steel ball 26 will always be placed in the groove and will not fall off. Of course, because the steel ball 26 will roll on the ground for a long time, dirt will adhere to the ball. The silicone ring 27 set on the outside of the groove can scrape off the dirt on the ball to prevent it from affecting the normal operation of the ball.

[0054] The two protective covers 4 are connected to each other through the curved plate 17, and at the same time, one side of the curved plate 17 slides in the deep groove 21 through the short column 23, so that one side of the curved plate 17 can be universally adjusted to a certain angle. At the same time, the other side of the curved plate 17 is hinged in the short groove 18 through the connecting column, so the other side of the curved plate 17 can be universally adjusted relative to the protective cover 4 on the other side. Of course, because the protective covers 4 on both sides can be retracted together, the curved plate 17 can enter the semicircular groove 22 and the deep groove 21, so that the protective covers 4 on both sides can be close together. The curved plate 17 can enable the protective cover 4 to be flipped at a certain angle, and a linear protrusion 19 is provided to keep the cross-sectional direction of the cable 2 and the relative position of the protective cover 4 fixed, so that when the cable 2 rotates, it can drive the following protective cover 4 to rotate at the same time. Of course, the cable 2 can be flipped during the closing process of the protective cover 4, but it cannot be rotated without restriction, to prevent the cable 2 from twisting and entangled due to long-term use.

[0055] When the next car is charging, it parks the vehicle in the parking space corresponding to the new energy vehicle charging pile, removes the charging gun 3 from the charging pile, and the drive motor 6 runs at this time, driving the winch 5 to rotate in the opposite direction to loosen the wire rope 15. At this time, the second compression spring 25 and the third compression spring 11 will return the protective shell to its original position. At this time, the cable 2 can be dragged as a whole to flip and move so that it can be inserted into the charging port of the vehicle to continue charging the new energy vehicle.

For those skilled in the art, various changes, modifications, substitutions, and variations to these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
