Description

Technical Field

[0001] This application relates to the field of charging device technology, and more particularly to a charging pile. Background Technology

[0002] New energy vehicles, such as electric vehicles, have a relatively smaller environmental impact compared to traditional gasoline-powered vehicles, leading to their widespread adoption. As the number of electric vehicles increases, the demand for charging stations to power them also grows. A charging station typically includes a charging cable that connects to the charging head and a cable for connecting to an external power source. When not in use, the charging head is usually hung outside the charging station, while the charging cable remains exposed to the external environment, making it susceptible to damage and affecting the lifespan of the charging station.

[0003] Charging stations capable of retracting cables have appeared on the market. When not in use, a motor drives a winding reel to wind up the cable, thus protecting it. However, because of the inclusion of a motor, belt, and other components, and the need for space between the motor and the winding reel, these charging stations are relatively large. Summary of the Invention

[0004] The purpose of this application is to provide a charging pile that, through the movable cooperation between the winding reel and the housing, reduces the size of the charging pile while the rotation of the winding reel can store the charging cable in the winding reel. By setting an electric slip ring connected to the winding reel, the cable is electrically connected to the electronic control component through the wiring part. Even when the cable is externally powered, the winding reel can be easily rotated to store the charging cable in the winding reel, regardless of the state of the cable.

[0005] Therefore, this application provides a charging pile, including:

[0006] The shell has an enclosed cavity and two through holes are provided along the transverse or longitudinal direction of the shell.

[0007] A winding spool, at least a portion of which is rotatably disposed in the inner cavity along the axial direction of the through hole, and an accommodating space is formed inside the winding spool;

[0008] An electronic control component is disposed in the accommodating space and can rotate with the winding reel;

[0009] A charging gun, which has a charging head and a charging cable, one end of which is electrically connected to the electronic control component and the other end is connected to the charging head. The rotation of the winding reel can store the charging cable in the winding reel.

[0010] An electric slip ring, which is coaxial with the winding reel; the electric slip ring includes a mating part and a connecting part that can rotate relative to each other, the mating part is connected to the winding reel and can rotate with the winding reel, and the connecting part can rotate relative to the mating part;

[0011] The cable is connected to the connector at one end and to a plug at the other end.

[0012] According to the charging pile provided in this application embodiment, when a user needs to charge, they can directly pull the charging cable of the charging gun out of the charging pile housing. At this time, the winding reel can rotate under the action of external force, allowing the charging cable stored in the winding reel to be led out. The user can then move the charging gun to the charging port position on the new energy vehicle body. The winding reel is rotatably arranged in the inner cavity of the housing along the axial direction of the through hole. When charging is completed, simply drive the winding reel to rotate in the opposite direction of the charging cable lead-out direction to wind and store the charging cable exposed outside the charging pile housing in the winding groove. This charging pile, through the movable cooperation between the winding reel and the housing, the cooperation between the winding reel, the slip ring, and the cable, and the design of the position of the electronic control components in the accommodating space, reduces the overall size of the charging pile while meeting the charging cable storage requirements.

[0013] Meanwhile, during the rotation of the winding reel to store or unsend the reel, the electric slip ring acts as a guide. By connecting the electric slip ring to the winding reel, the cable is electrically connected to the electronic control component through the wiring section. Whether the cable is externally powered, stored, or disconnected from the wiring section of the electric slip ring, the winding reel can be easily rotated to store the charging cable, unaffected by the cable's condition.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] See Figures 1 to 3 This application provides a charging pile for supplying power to new energy vehicles. The charging pile includes a housing 1, which encloses an inner cavity 14 and has two through holes 15 along its transverse or longitudinal direction; a winding reel 2, at least a portion of which is rotatably disposed axially along the through holes 15 within the inner cavity 14, and an accommodating space 24 is formed inside the winding reel 2; an electronic control component 5, disposed within the accommodating space 24 and rotatable with the winding reel 2; and a charging gun 4, which has a charging head 41 and a charging cable 42, one end of which is electrically connected to the electronic control component 5, and the other end connected to the charging head 41. Rotation of the winding reel 2 allows the charging cable 42 to be stored within it. The electric slip ring 7 is coaxial with the winding reel 2. The electric slip ring 7 includes a mating part 71 and a wiring part 72 that can rotate relative to each other. The mating part 71 is connected to the winding reel 2 and can rotate with the winding reel 2. The wiring part 72 can rotate relative to the mating part 71. The cable 8 is connected to the wiring part 72, and the other end is connected to the plug 81. The plug 81 is used to connect to an external power source.

[0037] When charging is needed, the user connects the charging station to mains power and then pulls the charging cable 42 of the charging gun 4 outward. At this time, the winding reel 2 rotates clockwise or counterclockwise under external force, allowing the charging cable 42 stored in the winding reel 2 to be smoothly extended. The user can then move the charging gun 4 to the charging port location of the new energy vehicle for charging. During this process, mains power, such as 220V AC, is transmitted to the electronic control component 5 through the external plug 81 and cable 8. The electronic control component 5 converts the 220V mains power into DC power compatible with the new energy vehicle. The DC power is then transmitted to the new energy vehicle being charged through the charging gun 4. When charging is complete, simply drive the winding reel 2 in the opposite direction of the rotation when the charging cable 42 was extended to rewind and store the exposed charging cable 42 back into the winding reel 2. Meanwhile, during the rotation of the winding reel 2 to receive or extend it, the external AC power cable 8 is electrically connected to the electronic control component 5 via the slip ring 7, supplying power to the electronic control component 5. Simultaneously, the slip ring 7 rotates through the mating part 71 and the wiring part 72, causing the winding reel 2 to rotate as the charging cable 42 is received or extended. The cable 8 connected to the wiring part 72 does not rotate with the winding reel 2. Whether the cable 8 is connected to AC power, in a received state, or disconnected from the wiring part 72 of the slip ring 7, the winding reel 2 can be easily rotated to receive the charging cable 42, unaffected by the state of the cable 8.

[0038] In an alternative embodiment, see Figures 2 to 8 The winding reel 2 includes a first connecting part 21 and a second connecting part 22, which are movably connected to the housing 1 at positions corresponding to the two through holes 15. The first connecting part 21 and the second connecting part 22 cooperate to form a winding groove 23 for storing the charging cable 42. By setting the winding reel 2 with the first connecting part 21 and the second connecting part 22 in a relatively cooperating manner, the first connecting part 21 and the second connecting part 22 are rotatably connected to the housing 1 at the through holes 15 on opposite sides of the housing 1. There is no need to set up an additional driving device (such as a motor) to drive the winding reel 2 to rotate. Ordinary users can rotate the winding reel 2 relative to the housing 1 by hand, thereby completing the storage or delivery of the charging cable 42.

[0039] Furthermore, the first connecting portion 21 includes a first connecting member 211 and a first end plate 212, and the second connecting portion 22 includes a second connecting member 221; the first connecting portion 21 also includes an annular wall 211a disposed around the center point of the first connecting member 211, the annular wall 211a extending perpendicularly relative to the first connecting member 211, and the second connecting portion 22 also includes an annular wall 211a disposed around the center point of the second connecting member 221, the annular wall 211a extending perpendicularly relative to the second connecting member 221; the two annular walls 211a are disposed opposite to each other to form an accommodating space 24, and the first connecting member 211, the second connecting member 221 and the two annular walls 211a together restrict the winding groove 23 on the outer ring of the accommodating space 24.

[0040] The first connector 211 and / or the second connector 221 are provided with slots 222. One end of the charging cable 42 passes through the annular wall 211a and connects to the electronic control component 5 in the accommodating space 24. The charging cable 42 is provided with a locking block 421, and the slot 222 engages with the locking block 421. While electrically connecting the charging cable 42 to the electronic control component 5 in the accommodating space 24, the matching slots 222 and locking blocks 421 prevent the charging cable 42 from disconnecting from the electronic control component 5 when pulled by external force, ensuring the stability of the connection between the charging cable 42 and the electronic control component 5. Furthermore, the matching of the slots 222 and locking blocks 421 facilitates the assembly of the charging pile and improves assembly efficiency.

[0041] Optionally, the cross-sectional shape of the annular wall 211a can be circular, square, rectangular, triangular, or other irregular shapes. The shape and size of the annular wall 211a can be appropriately selected according to the size and shape of the internal electronic control component 5. In this embodiment, a circular cross-section is preferred for the annular wall 211a. The circular annular wall 211a is more convenient to set up the snap-fit ​​structure, and the outer side of the annular wall 211a serves as the inner core of the accommodating space 24. When the two annular walls 211a are engaged, the cylindrical annular wall 211a is easy to store and saves effort.

[0042] The first connecting part 21 and the second connecting part 22 partially cooperate with each other on the outer side wall of the inner cavity 14 to form a winding groove 23 for storing the charging cable 42. The inner side wall encloses a receiving space 24 for installing and fixing the electronic control component 5. This charging pile reduces the overall volume of the charging pile while meeting the storage requirements of the charging cable 42 through the movable cooperation between the winding disc 2 and the housing 1, the structural connection of the first connecting part 21 and the second connecting part 22, and the design of placing the electronic control component 5 in the receiving space 24.

[0043] Optionally, the mating part 71 is fixedly connected to the second connecting part 22, and the mating part 71 at least partially extends into the receiving space 24 to be electrically connected to the electronic control component 5. The wiring part 72 includes a contact 721, which extends out of the mating part 71 to the side away from the receiving space 24. The cable 8 is fixedly connected to the contact 721. The mating part 71, fixedly connected to the second connecting part 22, enables the electrical connection between the slip ring 7 and the electronic control component 5, allowing the connected cable 8 to be used for external AC power. While the electronic control component 5 rotates with the winding reel 2, the cable 8 connected through the slip ring 7 is electrically connected to the electronic control component 5 without being affected by the rotation of the electronic control component 5, thus achieving the goal that whether the charging cable 42 is retracted or not does not affect the cable 8.

[0044] In an alternative embodiment, see Figures 2 to 8 The first connecting part 21 includes a first connecting member 211 and a first end plate 212, and the second connecting part 22 includes a second connecting member 221. The housing 1 includes a first side wall 121 and a second side wall 131 that are penetrated by a through hole 15. The first connecting member 211 is disposed near the first side wall 121 in the inner cavity 14, and the first end plate 212 is disposed near the first side wall 121 outside the inner cavity 14. The second connecting member 221 is disposed near the second side wall 131 in the inner cavity 14. A through frame 223 for setting an electric slip ring 7 is provided on the second connecting member 221, and at least part of the outer diameter of the electric slip ring 7 is fixed on the inner circumference of the through frame 223.

[0045] The first connector 211 and the first end plate 212, which are disposed along the axial direction H on the first side wall 121, cooperate with each other, and the second connector 221 cooperates with the inner wall of the second side wall 131, to achieve a movable connection between the connecting part and the housing 1, without the need for additional auxiliary driving components to drive the winding disc 2 to rotate. The first connector 211 and the first end plate 212, which are disposed on the inner and outer sides of the inner cavity 14, facilitate assembly. The first end plate 212 extends vertically toward the first connector 211 to form an annular extension piece 215. A snap-fit ​​groove 214 is provided at the end of the extension piece 215. The first connector 211 is provided with a clip 213 at the position of the annular snap-fit ​​groove 214. The first connector 211 and the first end plate 212 are snapped together by the clip 213 and the snap-fit ​​groove 214, and the first side wall 121 and the extension piece 215 are movablely engaged. Alternatively, the first connector 211 can extend vertically toward the first end plate 212 to form an annular extension piece 215. To improve the strength of the connection between the two, the first end plate 212 may be provided with annularly arranged screw holes, and the two can be detachably connected by the cooperation of screws and screw holes.

[0046] The through frame 223 on the second connector 221 is used to accommodate the slip ring 7, so that at least a portion of the outer diameter of the slip ring 7 can be fixedly connected to the inner circumference of the through frame 223. The through frame 223 facilitates the installation and fixation of the slip ring 7. At the same time, it allows the slip ring 7 to indirectly connect the electrical control component 5 in the accommodating space 24 to the external cable 8, so that the electrical control component 5 can be connected to the mains power through the cable 8.

[0047] It is understood that the slip ring 7 includes a rotatably connected mating part 71 and a wiring part 72. The outer wall of the mating part 71 is fixedly connected to the inner circumference of the through frame 223. The contact 721 on the wiring part 72 is used to connect the cable 8. The contact 721 can be, for example, a protrusion in the wiring part 72 that protrudes away from the receiving space 24. The size, shape, etc. of the contact 721 can be adapted to the specific situation of the cable 8 being connected, and no specific limitation is made here.

[0048] In one specific embodiment, the two through holes 15 are defined as a first through hole 151 located on the first sidewall 121 and a second through hole 152 located on the second sidewall 131, respectively. A first annular flange 121a extends vertically along the center line of the first through hole 151 from the inner side of the first sidewall 121. A first end plate 212 is disposed at the first through hole 151, and the outer surface of the first end plate 212 is substantially horizontal with the outer surface of the first sidewall 121. The first flange 121a restricts the first end plate 212 from moving toward the inner cavity 14. The connection point 721 between the first connector 211 and the first end plate 212 is in clearance fit with the first flange 121a. A rotating member 10 is disposed in the clearance. For example, the rotating member 10 can be a plurality of balls 101 arranged at intervals in the clearance to facilitate the rotation of the winding disc 2. The periphery of the first end plate 212 is provided with a plurality of ball grooves 102 corresponding to the balls 101 to facilitate the rotational connection between the winding disc 2 and the housing 1.

[0049] Optionally, an annular second flange extends vertically from the inner side of the second sidewall 131 along the centerline of the second through hole 152, and the second flange is opposite to the first flange 121a along the centerline of the second through hole 152. The second flange is located between the second connector 221 and the second side plate. Furthermore, there is a fitting gap between the second connector 221 and the second flange, and multiple balls 101 spaced apart within the fitting gap are provided to facilitate the rotation of the winding disc 2. A plurality of ball grooves 102 are provided on the periphery of the second flange corresponding to the balls 101, further ensuring the smoothness and stability of the rotational connection between the winding disc 2 and the housing 1.

[0050] It is understood that the ball groove 102 is used to restrict the balls 101 to prevent them from deviating from the preset motion trajectory, and also to prevent the balls 101 from accumulating in a localized area and affecting the rotation of the winding reel 2. It is also understood that the rotating component 10 can be configured as other structures that enable the winding reel 2 to rotate relative to the housing 11, and no specific limitation is made here.

[0051] More specifically, on the first connecting portion 21, numerous connecting points form an annular extension piece 215. A gap is formed between the extension piece 215 and the first flange 121a. The upper part of the ball bearing 101 disposed in the gap abuts against the first flange 121a, and the lower part abuts against the extension piece 215, so that there is a positional restriction between the first sidewall 121 and the first connecting portion 21, and the first connecting portion 21 can rotate relative to the first sidewall 121. The first connecting portion 21 is circular, and its diameter is larger than the diameter of the first through hole 151. It fits against the inner side of the first sidewall 121. The first end plate 212 is also circular, and its diameter is slightly smaller than the diameter of the through hole 15. The first flange 121a restricts the first end plate 212 from moving into the inner cavity 14. The snap-fit ​​connection between the first end plate 212 and the first connector 211 restricts the first end plate 212 from disengaging from the first connector 211 and moving away from the inner cavity 14. Of course, the cooperation relationship between the second connecting part 22 and the second side wall 131 is the same as that between the first connecting part 21 and the first side wall 121. The only difference is that an extension piece 215 with numerous connection points forming a ring is formed on the side wall of the second connecting member 221 to realize the connection between the second connecting member 221 and the second side wall 131.

[0052] Of course, for the first end plate 212, the outer ring of the side wall around the first through hole 151 can be removed at the original position of the first through hole 151 to increase the diameter of the outer ring of the first through hole 151, while the diameter of the inner ring of the first through hole 151 (the side closer to the inner cavity 14) remains unchanged, thereby restricting the first end plate 212 to the position of the outer ring of the first through hole 151 outside the inner cavity 14.

[0053] The outer surface of the first end plate 212 and the outer surface of the first side wall 121 are basically horizontal, that is, they are basically on the same plane, ensuring the aesthetics and integrity of the overall appearance.

[0054] In an alternative embodiment, see Figure 4 , Figure 5 and Figure 8The charging pile also includes a fastener 9, which seals the second through hole 152. The fastener 9 contacts and engages with the mating part 71 and the wiring part 72 respectively to restrict the movement of the mating part 71 and the wiring part 72 in the axial direction H. The fastener 9 has an opening 91, and a contact 721 extends from the opening 91 to connect the cable 8. By sealing the second through hole 152 with the fastener 9, the movement of the slip ring 7 in the axial direction H of the second through hole 152 is further restricted, preventing the slip ring 7 set in the through frame 223 from easily dislodging from the housing 1 under the action of external force, thereby improving the service life of the charging pile.

[0055] Specifically, the fastener 9 includes a sealing plate 93, an extension plate 94, and a baffle 92. The sealing plate 93 seals the second through hole 152, the extension plate 94 extends from the outer ring of the sealing plate 93 outwards from the second sidewall 131, and the baffle 92 is connected to the end face of the extension plate 94 and covers the second through hole 152. The fastener 9 can be configured as an inwardly recessed disc-shaped structure, with the sealing plate 93 forming the bottom surface of the inward recess for sealing the second through hole 152. The sealing plate 93 is located on the inner side of the second sidewall 131, and the baffle 92 extends to the outer side of the second sidewall 131 via the connected extension plate 94, allowing the fastener 9 to completely cover the second through hole 152.

[0056] When the fastener 9 seals the second through hole 152, the mating part 71 has a radially extending abutment surface 711 at one end facing the second side wall 131, and along the axial direction H, a portion of the wiring part 72 extends out of the mating part 71 towards the second side wall 131, and the extended portion has an annular surface. The sealing plate 93 abuts against the abutment surface 711 to restrict the fastener 9 from continuing to move in the direction of the inner cavity 14, and the opening 91 contacts or gap-fits the annular surface. The sealing plate 93 and the extension plate 94 enclose a clearance space 95, and the contact point 721 and part of the cable 8 are located within the clearance space 95 to ensure that the cable 8 can extend to the outside for external connection to mains power.

[0057] Understandably, the diameter of the first through hole 151 is larger than the diameter of the second through hole 152, so that they can respectively adapt to the connection of the first end plate 212 and the fastener 9.

[0058] Optionally, the diameter of the sealing plate 93 is smaller than the diameter of the second through hole 152, and the outer diameter of the baffle 92 is larger than the diameter of the second through hole 152. This allows the sealing plate 93 to easily extend into the second through hole 152 when the fastener 9 is assembled with the second sidewall 131, while the baffle 92 restricts its further movement into the inner cavity 14, facilitating installation and positioning and ensuring a better sealing effect.

[0059] In an alternative embodiment, see Figure 2 , Figure 5 , Figure 6 , Figure 8 and Figure 9 The charging station also includes a storage tray 6, which covers the fastener 9 and is fixedly connected to the second side wall 131 together with the baffle 92. The storage tray 6 and the second side wall 131 together define a storage space 61 for storing the cable 8. With the storage tray 6, when the charging station is not in use, the cable 8 can be stored in the storage space 61 to prevent the cable 8 from being exposed to the outside and easily damaged. In this mating structure, whether the cable 8 is stored in the storage space 61 or not, it is unrelated to the action of storing the charging cable 42 or leading it out from the winding tray 2, and there is no interference between the two. However, when the cable 8 is connected to the external mains power, it does not affect the charging gun 4 charging the car.

[0060] Optionally, the storage tray 6 includes a tray body and an annular sidewall 62 extending along one side. The annular sidewall 62 is coaxial with the tray body, and its diameter is larger than that of the extension plate 94. The annular sidewall 62 and the baffle 92 are respectively provided with corresponding screw holes 921. The annular sidewall 62 and the baffle 92 are in contact and fitted together and are fixedly connected to the second sidewall 131 by bolts passing through the screw holes 921. The annular sidewall 62, the second sidewall 131, and the tray body enclose a storage space 61 for storing the cable 8. The extension plate 94 has a notch 911, through which the cable 8 passes in a nearly perpendicular state to the connector 721. Alternatively, the notch 911 extends to the annular sidewall 62 so that the cable 8 can be easily wound around the annular sidewall 62.

[0061] Optionally, the second sidewall 131 is provided with a slot 131a for receiving the plug 81. This allows the plug 81 to be received in the slot 131a when the cable 8 is received in the storage space 61.

[0062] The housing 1 can be integrally formed, or it can include a first housing 12 and a second housing 13 that are detachably connected. The first housing 12 has a first sidewall 121, and the second housing 13 has a second sidewall 131, to facilitate the processing and assembly of the winding spool 2 within the inner cavity 14 of the housing 1. Regarding the specific detachable connection of the first housing 12 and the second housing 13, in this embodiment, to ensure the stability of the overall structure, the first housing 12 and the second housing 13 are fixed with screws, which also makes replacement very convenient.

[0063] By setting fixing posts around the electronic control component 5 in the accommodating space 24, the electronic control component 5 is fixed in the accommodating space 24 so that it rotates synchronously with the winding disc 2. This also avoids the impact of bumping the electronic control component 5 and the entanglement of the wire during rotation.

[0064] In an alternative embodiment, see Figure 7 and Figure 9The charging station also includes a control panel, which is located on the outer surface of the first end plate 212 and electrically connected to the electronic control component 5. The control panel can rotate synchronously with the first end plate 212. The control panel includes a display screen 51 and buttons 52. Button 52 is a touch button that can adjust the scheduled charging and the flashing charging color prompts. The display screen 51 can display the charging current, such as 32A, 40A, etc., and the charging time. The scheduled charging method involves connecting to the mains power and the new energy vehicle charging port, and then selecting to start charging after half an hour, two hours, etc.

[0065] Optionally, a handle 212a is vertically connected to the outer surface of the first end plate 212, and the handle 212a is located near the outer edge of the first end plate 212. The handle 212a allows the user to manually rotate the winding reel 2 after using the charging station, enabling the charging cable 42 to be retracted into the winding groove 23. The handle 212a is positioned further away from the center point, increasing the distance between the handle 212a and the center point, thus increasing torque and reducing effort, making it easier for the user to operate.

[0066] Optional, see Figure 10 The housing 1 has an outlet 17 on either side away from the two through holes 15 for the charging cable 42 to extend out. Two opposing rotating cylinders 18 are located at the outlet 17, and the charging cable 42 extends from between the two rotating cylinders 18. At least one rotating cylinder 18 rotates as the charging cable 42 extends. The housing 1 also has a charging slot 16 for holding the charging head 41, positioned above the outlet 17. In the non-use state, the charging head 41 is engaged in the charging slot 16, and the charging cable 42 is stored in the winding groove 23. When charging is needed, the user simply removes the charging head 41 and moves it, putting the charging cable 42 under tension. Under this tension, the winding disc 2 rotates relative to the housing 1, allowing the charging cable 42 to exit from the winding groove 23. At the same time, the rotating drum 18 rotates as the charging cable 42 extends. The rotating drum 18 makes the charging cable 42 smoother when it is pulled out and can prevent the charging cable 42 from being damaged due to friction with the cable outlet 17.

[0067] In an alternative embodiment, see Figure 1 , Figure 2 and Figure 7The top of the housing 1 is provided with a handle 11, which is fixedly connected to the housing 1 or is an integral structure with the housing 1. It can be moved and placed in any position for charging according to the user's needs. Alternatively, the handle 11 can also extend and retract relative to the housing 1 in the height direction. The housing 1 corresponding to the position of the handle 11 is provided with a handle avoidance recess 111. Under no external force, the handle 11 is accommodated in the avoidance recess 111. When an external force is applied upward to the handle 11, the handle 11 is pulled out from the avoidance recess 111, reducing the overall volume of the charging pile and preventing the handle 11 from being easily damaged by collision when it extends out of the housing 1.

[0068] In an alternative embodiment, see Figure 7 The outer side of the housing 1 is provided with a mounting component 3, which includes a mounting piece 31 fixedly connected to the housing 1 and a connecting piece 32 hinged to the mounting piece 31. It is understood that the mounting piece 31 can be a flat sheet structure installed only on one side wall of the housing 1, or it can be an L-shaped structure fixed to both the side wall and bottom wall of the housing 1 respectively, to provide structural stability for the fixed connection. When the charging pile does not need to be moved, the connecting piece 32 can be used to fix it to the charging pile or a wall. The hinged connection between the mounting piece 31 and the connecting piece 32 allows for appropriate adjustment of the position and angle of the charging pile under fixed conditions, maximizing the docking with the new energy vehicle.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
