Description

Technical Field

[0001] The present application relates to the field of charging pile protection design, and in particular to a protective shell for a new energy vehicle charging pile. Background Art

[0002] Charging piles refer to charging equipment that provides charging services for new energy electric vehicles. They are mainly divided into floor-standing charging piles and wall-mounted charging piles. They are installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. Their input end is directly connected to the AC power grid, and the output end is equipped with a charging plug. They can charge various models of electric vehicles according to different voltage levels.

[0003] The protective shell of the charging pile is an important part of the charging pile, which plays a vital role in the safe operation of the charging pile and the safe use of users. It needs to have a series of characteristics such as moisture resistance, fire resistance, collision resistance and corrosion resistance. In the related art, the Chinese patent application publication number CN117382456A discloses a charging pile protection device, in which the charging cable connected to the charging plug is wound by a winding mechanism. After the winding is completed, the charging cable will be wound into a coil in the winding drum, which plays the role of cable management.

[0004] However, when the car is charged on a rainy day and the owner plugs the charging plug back into the charging pile, rainwater will be attached to the surface of the charging cable; if the charging cable is directly rolled into a winding drum and wound into a roll, the attached rainwater will be difficult to evaporate and remove, and the cable surface will be in a wet state for a long time, which will cause the service life to be reduced; what's more, if the charging pile is built in the northern region and the weather is cold in winter, if there is still rainwater on the surface of the charging cable and it is stored in the winding drum, the rainwater may solidify and cause local adhesion and curing of the charging cable. It is difficult to pull the cured charging cable out of the winding drum, which affects the normal use of the charging pile and needs to be improved. Summary of the invention

[0005] Based on this, the present application provides a protective casing for a new energy vehicle charging pile, which can quickly dry rainwater attached to the surface of the charging cable, thereby maintaining a good service life of the charging cable.

[0006] The protective shell of a new energy vehicle charging pile provided in this application adopts the following technical solution:

[0007] A protective shell for a new energy vehicle charging pile comprises a shell body and a storage cover arranged on the front of the shell body, a storage chamber for storing charging cables is formed between the storage cover and the shell body, and a plurality of rotating rollers and a plurality of sliding rollers are arranged inside the storage chamber;

[0008] The rotating roller is rotatably mounted on the shell body, and the sliding roller is slidably connected to the shell body; each sliding roller is located between two adjacent rotating rollers, and each sliding roller is normally arranged side by side with each rotating roller, and the charging cable is alternately wound around each rotating roller and each sliding roller in turn, and a heat drying device for blowing hot air is provided inside the storage chamber;

[0009] The shell body is separated by a partition to form a control room, one end of the sliding roller is inserted into the control room and connected to a connecting seat, a hook is movably mounted on the connecting seat, and a first spring is arranged between the hook and the connecting seat, and the first spring is used to force the hook to move outward normally;

[0010] A driving mechanism is fixed inside the control room, and the movable end of the driving mechanism is connected to a limiting component. When the charging pile is in the initial state, the limiting component is outside the moving path of the connecting seat; when the charging pile is in use, the driving mechanism forces the limiting component to move to the moving path of the connecting seat, and the hook can cooperate with the limiting component to hook and limit.

[0011] By adopting the above technical solution, when the user uses the charging pile of the present application to charge the car on a rainy day, the driving mechanism drives the limiting member to move to the moving path of the connecting seat. At this time, after the user pulls the charging cable outward, the hook of the connecting seat can cooperate with the limiting member to hook, so that the charging cable remains in the state of being pulled out, which is convenient for the user to charge the car. When charging is completed, the charging plug is re-inserted into the charging pile to change the state of the driving mechanism. At this time, the limiting member moves out of the moving path of the connecting seat, and the hook and the limiting member are separated from each other; by resetting each sliding roller to a position arranged side by side with each rotating roller, the charging cable can be in a spread state in the storage room, and the local sections of the charging cable do not contact each other; by controlling the operation of the heat drying device to blow hot air into the storage room, the rainwater attached to the surface of the charging cable can be quickly dried and evaporated, which is conducive to improving the problem of reduced cable skin life and maintaining a good service life of the charging cable.

[0012] Optionally, a plurality of sliding grooves are provided on the front side of the outer shell body, and each sliding roller is slidably installed in the corresponding sliding groove, and each sliding roller is arranged to rotate freely; a plurality of anti-rotation grooves are provided on the inner side surface of the outer shell body, and each anti-rotation groove is arranged to overlap with each sliding groove and is correspondingly connected, the connecting seat is partially located in the anti-rotation groove, and the two opposite side surfaces of the connecting seat are respectively abutted against the two opposite inner walls of the anti-rotation groove.

[0013] By adopting the above-mentioned technical solution, the setting of the sliding groove can enable the sliding roller to move in the storage chamber, and since the connecting seat is slidably set in the anti-rotation groove, the two opposite side walls of the connecting seat are respectively abutted against the two opposite inner walls of the anti-rotation groove, which can limit the rotation of the connecting seat, so that after the connecting seat moves, the hook part can smoothly hook and limit the position with the limiting component.

[0014] Optionally, a track plate frame is fixed to the inner wall of the control chamber, the track plate frame has a first slide and a second slide that are connected to each other, and the second slide is inclined toward the direction close to the storage chamber; a sliding block is fixed to the end of the limiting member, and the sliding block is slidably set between the first slide and the second slide; the driving mechanism is set as an electric push rod, the fixed end of the electric push rod is rotatably connected to the inner wall of the control chamber, the movable end of the electric push rod is fixed with a ring, and the limiting member is partially penetrated by the ring and is freely rotatable.

[0015] By adopting the above-mentioned technical solution, when the electric push rod is in the initial state, the sliding block stays inside the first slide, and at this time the limiting member can remain outside the moving path of the sliding roller; when the user pays the fee at the charging pile, the state of the electric push rod changes, and its movable end retracts inward, which can drive the sliding block to enter the second slide, and at this time the limiting member can be located on the moving connection of the sliding roller, and then after the user pulls the charging cable outward and moves the sliding roller toward the direction close to the rotating roller, the hook can smoothly cooperate with the limiting member to hook and limit, and at this time the charging cable can remain in a state of being pulled outward, so that the user can charge the car.

[0016] Optionally, multiple groups of reset mechanisms are provided inside the control room, and each group of reset mechanisms is arranged opposite to each sliding roller; wherein the reset mechanism includes a spring seat fixed to the outer shell body, a push block movably connected to the spring seat, and a second spring arranged between the push block and the spring seat, and the second spring normally forces the push block to move away from the spring seat; when the hook and the limiting member are hooked, the connecting seat partially abuts against the push block and forces the second spring to be in a compressed state.

[0017] By adopting the above-mentioned technical solution, after the user completes charging the car and plugs the charging plug back into the charging pile, the state of the driving mechanism changes so that the hook part disengages from the limiting component. At this time, the sliding roller can automatically move along the sliding groove away from the rotating roller under the elastic force of the second spring, thereby facilitating the reset movement of the sliding roller, which is beneficial for keeping the charging cable inside the storage chamber in an extended state.

[0018] Optionally, multiple groups of sealing structures are provided inside the control room, and each group of sealing structures is arranged corresponding to each anti-rotation groove; wherein the sealing structure includes two flexible sealing strips, the two flexible sealing strips are respectively bonded to the inner side surface of the outer shell body, and the two flexible sealing strips jointly cover the anti-rotation groove.

[0019] By adopting the above-mentioned technical solution and setting a flexible sealing strip to cover the anti-rotation groove, the possibility of moisture inside the storage chamber entering the shell body can be reduced, so that the interior of the charging pile remains dry and electrical safety is ensured, while the various driving parts inside the control room maintain a good mechanical life.

[0020] Optionally, a wiring hole for the charging cable to pass through is provided on the side of the storage cover, and the sliding roller closest to the wiring hole among all the sliding rollers is set as the main sliding roller, and the main sliding roller forces the charging cable to be in a spread state by its own gravity;

[0021] The remaining sliding rollers are set as secondary sliding rollers, and a plurality of groups of holding mechanisms are arranged inside the control room. Each group of holding mechanisms is respectively arranged at each secondary sliding roller, so as to keep the secondary sliding roller in position in the initial state; when the sliding roller is in a state where the hook part and the limiting member are hooked together, the connecting seat can force the adjacent holding mechanism to disengage from the secondary sliding roller to realize the sequential sliding of each sliding roller.

[0022] By adopting the above-mentioned technical solution, the setting of the holding mechanism can limit the movement of the secondary sliding roller in the sliding groove. When the user makes a payment at the charging pile and pulls the charging cable outward, the main sliding roller is first moved in the direction close to the rotating roller; after the main sliding roller moves to the hook and the limiting member to cooperate and hook, the main sliding roller can force the adjacent holding mechanism to disengage from the corresponding secondary sliding roller, so that the user can continue to pull the charging cable outward, which is conducive to improving the smoothness of pulling the charging cable and reducing the possibility of accidental damage to the charging cable due to violent pulling.

[0023] Optionally, the holding mechanism includes a special-shaped component slidably arranged inside the control chamber and a third spring arranged between the special-shaped component and the housing body, the third spring normally forces the special-shaped component to abut against the corresponding sliding roller, and when the charging pile is in the initial state, the sliding roller stays at the end of the sliding groove away from the rotating roller;

[0024] A guide groove is partially provided on the special-shaped component, and a guide piece is partially fixed on the connecting seat on the sliding roller adjacent to the special-shaped component. The guide piece is arranged along the sliding path of the sliding roller and opposite to the guide groove. When the sliding roller moves to the point where the hook piece cooperates with the limiting component to hook, the guide piece enters the guide groove and forces the special-shaped component to move in a direction close to the sliding roller.

[0025] By adopting the above-mentioned technical solution, when the user pulls the charging cable outward, the sliding roller will be subjected to force and move along the extension direction of the sliding groove; when the sliding roller moves to a position away from the rotating roller, the guide member can enter the guide groove and force the special-shaped component to move in the direction close to the sliding roller. At this time, the special-shaped component leaves the corresponding sliding roller, so that when the user continues to pull the charging cable, the next sliding roller can continue to be subjected to force and move along the sliding groove where it is located, thereby improving the smoothness of the user pulling the charging cable.

[0026] Optionally, the inner wall of the guide groove on one side close to the wiring hole is set as a first inclined guide surface, and the guide member has a second inclined guide surface abutting against the first inclined guide surface, so as to enable the guide member to smoothly force the special-shaped component to move when entering the guide groove; the inner wall of the guide groove on one side away from the wiring hole is set as a vertical surface.

[0027] By adopting the above technical solution, when the guide member enters the guide groove, the abutment between the first inclined guide surface and the second inclined guide surface can gradually force the special-shaped component to move toward the wiring hole, thereby smoothly making the special-shaped component leave the corresponding sliding roller.

[0028] Optionally, the holding mechanism also includes a rocker member rotatably arranged inside the control chamber, the rocker member is located on the side of the special-shaped component close to the wiring hole; a linear pushing mechanism is provided inside the control chamber, the linear pushing mechanism includes a screw member rotatably mounted inside the control chamber and a driving motor for driving the screw member to rotate, and a pushing seat is provided on the threaded sleeve of the screw member. When the driving motor is operating, the pushing seat can abut against each rocker member in turn along the direction close to the wiring hole to force the corresponding special-shaped component to return to its initial position.

[0029] By adopting the above technical solution, when the user completes charging the car and plugs the charging plug back into the charging pile, the state of the driving mechanism is first changed, so that the hook member is disengaged from the limiting member, and then the driving motor is operated to move the push seat along the axial direction of the screw member. The push seat can be pressed against each rocker member in turn along the direction close to the wiring hole, thereby using the lever principle to force the special-shaped member to return to the initial position and press against the sliding roller in the sliding groove; based on this, each sliding roller can be reset in sequence, so that the charging cable can be automatically reset to the extended state smoothly.

[0030] Optionally, the outer side of the storage cover is provided with a water shield covering the wiring hole, the bottom of the water shield is open and a guide roller is rotatably mounted, and the charging cable passes around the bottom of the guide roller.

[0031] By adopting the above-mentioned technical solution, the setting of the water barrier can reduce the possibility of rainwater entering the storage room through the wiring hole on rainy days, thereby ensuring that the internal environment of the storage room is dry; in addition, by setting a guide roller, the charging cable bypasses the bottom of the guide roller, which can improve the scratching between the surface of the charging cable and the inner wall of the wiring hole, which is beneficial to maintain a good service life of the charging cable.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. By setting the rotating roller and the sliding roller, the sliding rollers of the charging pile are reset to the position arranged side by side with the rotating rollers in the initial state, so that the charging cable can be spread out in the storage room; by controlling the hot drying device to blow hot air into the storage room, the rainwater attached to the surface of the charging cable can be quickly dried and evaporated, which is conducive to maintaining a good service life of the charging cable;

[0050] The following is combined with Figure 1-11 This application is described in further detail.

[0051] The embodiment of the present application discloses a protective casing for a new energy vehicle charging pile.

[0052] Reference Figure 1A protective shell for a new energy vehicle charging pile includes a shell body 1 and a storage cover 2 fixed to the front of the shell body 1. A storage chamber 21 for storing a charging cable 3 can be formed between the storage cover 2 and the shell body 1. One end of the charging cable 3 is inserted into the shell body 1 and connected to a power supply device; a wiring hole 22 is provided on one side of the storage cover 2, and the other end of the charging cable 3 passes through the wiring hole 22 and is exposed to the shell body 1, and the exposed end of the charging cable 3 is fixedly connected to a charging plug 31 for power supply, and a power socket 19 for plugging and placing the charging plug 31 is provided on the side of the shell body 1.

[0053] Reference Figure 2 A water shield 23 is provided on the outer side of the storage cover 2, and the water shield 23 is provided on the wiring hole 22, and the water shield 23 and the storage cover 2 are integrally formed; the bottom of the water shield 23 is open, and a guide roller 24 is provided on the open side rotation frame of the water shield 23. After the charging cable 3 passes through the wiring hole 22, it can bypass the bottom of the guide roller 24, which is used to reduce the scratching and wear between the surface of the charging cable 3 and the inner wall of the wiring hole 22, which is beneficial to maintain a good service life of the charging cable 3.

[0054] Back to Figure 1 , a plurality of rotating rollers 4 and a plurality of sliding rollers 5 are arranged inside the storage chamber 21, wherein each rotating roller 4 is rotatably connected to the front of the shell body 1, and all the rotating rollers 4 are arranged equidistantly in the horizontal direction. A plurality of sliding grooves 12 are also arranged on the front of the shell body 1. In this embodiment, the sliding grooves 12 penetrate the inner and outer sides of the shell body 1, and the extension direction of the sliding grooves 12 is the same as the vertical direction, and each sliding groove 12 is located between two adjacent rotating rollers 4. The number of sliding rollers 5 is equal to the number of sliding grooves 12, and each sliding roller 5 is slidably installed in the corresponding sliding groove 12, and the cross-sectional shape of each sliding roller 5 is circular, so that the sliding roller 5 can freely rotate around its own central axis while moving in the sliding groove 12.

[0055] The charging cable 3 is alternately wound around each rotating roller 4 and each sliding roller 5 in sequence. When the charging pile is in the initial state, the sliding roller 5 can move along the sliding groove 12 to the position farthest from the rotating roller 4. At this time, each sliding roller 5 can be arranged side by side with each rotating roller 4 and staggered, so that the charging cable 3 is in a spread state, and the sections of the charging cable 3 do not contact each other. A heat drying device 14 is provided inside the storage chamber 21. The heat drying device 14 is fixed on the top of the storage chamber 21. By controlling the operation of the heat drying device 14, hot air can be blown into the storage chamber 21. Then, when the weather is cold and rainy, after the user completes charging and the charging cable 3 is re-stored in the storage chamber 21, the heat on the surface of the charging cable 3 can be quickly evaporated by heat drying, which is conducive to maintaining a good service life of the charging cable 3. A heat dissipation structure can be provided on the outer side of the storage cover 2 to allow the water vapor evaporated by heat to leave the storage chamber 21.

[0056] It should be noted here that the initial state mentioned above is the state when the charging pile is not in use and is in standby mode; if the user pays the fee on the charging pile, the charging pile will switch to the use state.

[0057] Reference Figure 3 A partition 11 is provided inside the shell body 1, and each side of the partition 11 is fixed to the inner wall of the shell body 1, so as to separate the inside of the shell body 1 into a control room 111. Figure 4 One end of the sliding roller 5 is inserted into the control chamber 111 and is rotatably connected to a connecting seat 51, and the cross-sectional shape of the connecting seat 51 is rectangular. A plurality of anti-rotation grooves 13 are provided on the inner side of the housing body 1, and the number of the anti-rotation grooves 13 is equal to the number of the sliding grooves 12, and each anti-rotation groove 13 is respectively arranged to overlap with each sliding groove 12 and is correspondingly connected; in this embodiment, the groove width of the anti-rotation groove 13 is set equal to the width of the connecting seat 51, that is, the two opposite side surfaces of the connecting seat 51 can respectively abut against the two opposite inner side walls of the anti-rotation groove 13, so as to limit the rotation of the connecting seat 51.

[0058] In addition, multiple groups of sealing structures 15 are provided inside the control room 111. The number of sealing structures 15 is equal to the number of anti-rotation grooves 13, and each group of sealing structures 15 is respectively provided corresponding to each anti-rotation groove 13. Specifically, the sealing structure 15 includes two flexible sealing strips 151, which can be made of silicone or rubber material; the two flexible sealing strips 151 are respectively bonded to the inner side of the shell body 1, and the two flexible sealing strips 151 extend toward each other and cover the anti-rotation groove 13 together, which can reduce the possibility of moisture inside the storage room 21 entering the inside of the shell body 1, so that the inside of the charging pile remains dry and ensures electrical safety.

[0059] Reference Figure 5A first movable groove 511 is opened on the side of the connecting seat 51 away from the sliding roller 5, and the opening direction of the first movable groove 511 is the same as the horizontal direction; a hook member 52 is movably installed inside the first movable groove 511, and a first spring 53 is installed between the hook member 52 and the inner end wall of the first movable groove 511, and the first spring 53 can always generate an elastic force acting on the hook member 52, thereby normally forcing the hook member 52 to be exposed from the connecting seat 51; in addition, a blocking member 512 for preventing the hook member 52 from escaping from the first movable groove 511 is also provided at the notch end of the first movable groove 511.

[0060] Back to Figure 4 A driving mechanism is provided inside the control room 111. The driving mechanism in this embodiment is configured as an electric push rod 16. The fixed end of the electric push rod 16 is rotatably connected to the inner wall of the control room 111. The movable end of the electric push rod 16 is connected to the limiting member 6. The specific connection method is as follows: a sleeve 161 is fixed to the movable end of the electric push rod 16, and a round rod segment 61 is fixed to the end in the extension direction of the limiting member 6. The round rod segment 61 can be matched and inserted into the inside of the sleeve 161, and the round rod segment 61 can rotate circumferentially around its own central axis.

[0061] Reference Figure 6 , the inner wall of the control room 111 is fixed with a track frame 17, and the track frame 17 has a first slide 171 and a second slide 172 that are interconnected, wherein the first slide 171 is vertically arranged, and the second slide 172 is inclined toward the direction close to the storage room 21. The end of the limiting member 6 is fixed with a sliding block 62, and the sliding block 62 is slidably arranged between the first slide 171 and the second slide 172. It should be noted here that the shape of the sliding block 62 in this embodiment is a parallelogram. When the sliding block 62 is located inside the first slide 171, the two opposite sides of the sliding block 62 can respectively abut against the two inner side walls of the first slide 171; and when the sliding block 62 enters the second slide, the other two opposite sides of the sliding block 62 can respectively abut against the two inner side walls of the second slide 172, so as to keep the direction of the limiting member 6 unchanged.

[0062] When the charging pile is in the initial state, the sliding block 62 is located inside the first slideway 171, and the limiting member 6 can be located outside the moving path of the connecting seat 51. When the charging pile is in use, the electric push rod 16 moves and forces the sliding block 62 to enter the second sliding interior, and the limiting member 6 moves to the moving path of the connecting seat 51, so that the hook 52 can cooperate with the limiting member 6 to hook and limit.

[0063] Specifically, back to Figure 5The side surface of the hook member 52 away from the first spring 53 is set as an inclined surface. When the hook member 52 moves toward the direction close to the limiting member 6, the inclined surface can first abut against the limiting member 6 and force the hook member 52 to move inward; after the hook member 52 moves to above the limiting member 6, the hook member 52 is reset outward under the elastic force of the first spring 53, so that the bottom surface of the hook member 52 can cooperate with the limiting member 6 to abut and limit, thereby realizing the position maintenance of the sliding roller 5.

[0064] Back to Figure 4 , a plurality of reset mechanisms 7 are arranged inside the control room 111, and each reset mechanism 7 is arranged opposite to each sliding roller 5; Figure 7 The reset mechanism 7 includes a spring seat 71, a push block 72 and a second spring 73. The spring seat 71 is fixed to the inner side of the housing body 1. The side of the spring seat 71 close to the sliding roller 5 is provided with a second movable groove 711. The push block 72 is movably installed inside the second movable groove 711. The second spring 73 is installed between the push block 72 and the inner bottom wall of the second movable groove 711. The second spring 73 can always generate an elastic force acting on the push block 72, thereby normally forcing the push block 72 to move in a direction away from the spring seat 71.

[0065] It should be noted here that when the sliding roller 5 moves upward along the sliding groove 12 and the hooking member 52 is hooked with the limiting member 6, the connecting seat 51 can abut against the pushing block 72 and force the pushing block 72 to move upward. At this time, the second spring 73 is in a compressed state; when the user completes charging the car and reinserts the charging plug 31 back into the power socket 19 of the charging pile, the electric push rod 16 resets and drives the sliding block 62 back to the first slideway 171, which can make the limiting member 6 and each hooking member 52 disengage from each other. At this time, the sliding roller 5 can automatically reset and move in the direction away from the rotating roller 4 under the elastic force of the corresponding second spring 73.

[0066] Reference Figure 8 In this embodiment, the sliding roller 5 closest to the wiring hole 22 among all the sliding rollers 5 is set as the main sliding roller 54. The connecting seat 51 on the main sliding roller 54 is fixedly connected with a counterweight block, which can increase the overall weight of the main sliding roller 54 so that the main sliding roller 54 can force the charging cable 3 to be in a spread state by its own gravity. The remaining sliding rollers 5 are set as secondary sliding rollers 55. A plurality of groups of holding mechanisms 8 are arranged inside the control room 111. The specific number of the holding mechanisms 8 is equal to the number of the secondary sliding rollers 55. Each group of holding mechanisms 8 is respectively arranged corresponding to each secondary sliding roller 55, which can keep the secondary sliding roller 55 in position in the initial state and stay at the end of the sliding groove 12 away from the rotating roller 4.

[0067] Specific reference Fig. 9The holding mechanism 8 includes a special-shaped member 81, a third spring 82 and a rocker member 83. A crossbar 18 is fixedly mounted on the inner side of the housing body 1. A guide seat 815 is fixed on the side of the special-shaped member 81. The guide seat 815 is provided with a plug hole for the crossbar 18 to pass through. The plug hole and the crossbar 18 cooperate to enable the special-shaped member 81 to move along the crossbar 18, thereby realizing the movement of the special-shaped member 81 inside the control room 111. It should be noted here that the sliding direction of the special-shaped member 81 is the same as the horizontal direction.

[0068] Also refer to Figure 8 , a ring plate seat 181 is partially fixed to the cross bar 18, and the ring plate seat 181 is located on the side of the special-shaped component 81 close to the wiring hole 22. The third spring 82 is sleeved on the cross bar 18, one end of the third spring 82 abuts against the ring plate seat 181, and the other end of the third spring 82 is connected to the special-shaped component 81; the third spring 82 can always generate an elastic force acting on the special-shaped component 81, thereby forcing the special-shaped component 81 to move away from the wiring hole 22, and making the special-shaped component 81 normally abut against the corresponding sliding roller 5. It should be noted here that when the charging pile is in the initial state, the bottom of the special-shaped component 81 can abut against the connecting seat 51 of the secondary sliding roller 55, and make the sliding roller 5 stay at the end of the sliding groove 12 away from the rotating roller 4.

[0069] Reference Fig.10 The side of the special-shaped component 81 has an extension portion 811 extending toward the storage chamber 21, and the extension portion 811 is provided with a guide groove 812; wherein the inner wall of the guide groove 812 on one side close to the wiring hole 22 is inclined and is set as a first inclined guide surface 813, and the inner wall of the guide groove 812 on one side away from the wiring hole 22 is set as a vertical surface 814. The sliding roller 5 located in the direction close to the wiring hole 22 and adjacent to the special-shaped component 81 is provided with a guide member 56 (such as Figure 5 As shown in the figure, the guide member 56 is fixedly connected to the connecting seat 51; the guide member 56 is arranged along the sliding path of the sliding roller 5 and opposite to the guide groove 812, and the guide member 56 has a second inclined guide surface 561 that abuts against the first inclined guide surface 813.

[0070] Back to Figure 8Taking the main sliding roller 54 as an example, when the main sliding roller 54 moves upward along the sliding groove 12, the second inclined guide surface 561 of the guide member 56 can firstly contact with the first inclined guide surface 813 of the guide groove 812, and then during the movement of the sliding roller 5, the guide member 56 can gradually force the special-shaped component 81 to move in the direction close to the wiring hole 22, so that the special-shaped component 81 gradually leaves the corresponding secondary sliding roller 55; when the main sliding roller 54 moves to the position where the hook member 52 cooperates with the limiting member 6 to hook, the special-shaped component 81 can completely separate from the secondary sliding roller 55, and at this time, the secondary sliding roller 55 can slide vertically along the sliding groove 12 where it is located. The other secondary sliding rollers 55 are similar, based on this, the sliding of each sliding roller 5 can be realized in sequence.

[0071] Back to Fig. 9 A rotating shaft 831 is fixed in the middle of the rocker member 83, and the rocker member 83 can be rotatably connected to the partition 11 through the rotating shaft 831, and the rocker member 83 of each group of retaining mechanisms 8 is arranged on the side of the special-shaped component 81 close to the wiring hole 22; a torsion spring 832 is also arranged between the rocker member 83 and the shell body 1, and the torsion spring 832 can always generate an elastic force acting on the rocker member 83, so that the bottom end of the rocker member 83 can be against the special-shaped component 81 under normal conditions.

[0072] Reference Fig.11 A linear push mechanism 9 is arranged inside the control room 111, and the linear push mechanism 9 includes a screw member 91, a drive motor 92 and a push seat 93; wherein, the screw member 91 is rotatably mounted on the inner top surface of the partition 11, and the axial direction of the screw member 91 is the same as the horizontal direction; the drive motor 92 is fixed to the inner top surface of the partition 11, and the output end of the drive motor 92 is coaxially connected to the screw member 91, so that the drive motor 92 can drive the screw member 91 to rotate when it is running.

[0073] A through thread groove is provided in the middle of the push seat 93, and the push seat 93 is threadedly sleeved on the screw member 91 through the thread groove, and one side surface of the push seat 93 can be pressed against the inner top surface of the partition 11, thereby limiting the rotation of the push seat 93, so that the push seat 93 can move along the axial direction of the screw member 91 when the drive motor 92 is running. It should be noted here that the push seat 93 and the special-shaped component 81 are respectively arranged on the upper and lower sides of the rotating shaft 831, and the top end of each rocker member 83 is located on the moving path of the push seat 93; in the initial state, the push seat 93 will be located at the end of the screw member 91 away from the wiring hole 22.

[0074] Also refer to Figure 8When the user finishes charging the car and re-inserts the charging plug 31 into the power socket 19 of the charging pile, the electric push rod 16 is reset so that each hook member 52 is separated from the limiting member 6, and the sliding roller 5 can move downward along the sliding groove 12 under the elastic force of the corresponding second spring 73, so that the guide member 56 smoothly leaves the guide groove 812 via the vertical surface 814; then the driving motor 92 is turned on and moves the push seat 93 toward the direction close to the wiring hole 22, and the push seat 93 can be against each rocker member 83 in turn. The lever principle can be used to make the rocker member 83 push the corresponding special-shaped member 81 back to the initial position, that is, the special-shaped member 81 returns to the position of the bottom end against the sliding roller 5, which can limit the movement of the sliding roller 5 in the sliding groove 12 and make the charging cable 3 in the spreading state again.

[0075] It is understandable that the order of resetting the sliding rollers 5 is from the sliding rollers 5 far away from the wiring hole 22 to the sliding rollers 5 close to the wiring hole 22, which can facilitate the smooth resetting of the charging cable 3 to the extended state.

[0076] The implementation principle of a protective shell of a new energy vehicle charging pile in the present application embodiment is:

[0077] When a user uses the charging pile of the present application to charge a car, he pulls the charging cable 3 outward after paying the fee. Each sliding roller 5 can be moved upward, so that the hook 52 of the connecting seat 51 cooperates with the limiting member 6 to hook and limit. At this time, the charging cable 3 can remain pulled out as a whole, which is convenient for the user to charge the car.

[0078] When charging is completed and the user reinserts the charging plug 31 into the power socket 19 of the charging pile, the electric push rod 16 is reset so that each hook member 52 is disengaged from the limiting member 6, and the sliding roller 5 can be reset downward under the elastic force of the corresponding second spring 73; then the driving motor 92 is operated to drive each sliding roller 5 to reset in sequence, so that the charging cable 3 can be automatically reset to the spread state, and the local sections of the charging cable 3 do not contact each other; at this time, the heat drying device 14 is controlled to operate, so that the rainwater attached to the surface of the charging cable 3 on rainy days can be quickly dried and evaporated, which is beneficial to improve the problem of reduced life of the cable surface and keep the charging cable 3 in a good service life.

[0079] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
