The electrical box is electrically connected to the battery boxes. The lifting mechanism is mounted on the chassis, with part of the lifting mechanism positioned between the battery boxes and the electrical box, and part positioned on the side of the battery box away from the electrical box. This application optimizes the layout of the lifting mechanism by positioning part of it between the battery boxes and the electrical box and part of it on the side of the battery box away from the electrical box.

Description

Technical Field

[0001] This application relates to the field of charging technology, and in particular to a charging device and charging system. Background Technology

[0002] With the rapid development of new energy technologies, the application of electric vehicles, electric construction machinery, and other equipment is becoming increasingly widespread, and the demand for supporting charging equipment is also continuously growing. To meet the needs of outdoor operations, emergency power supply, and mobile charging scenarios, small mobile charging equipment has emerged. These devices typically need to be transported to the target location by vehicle, offering the advantage of flexible deployment. In related technologies, the lifting mechanism in the structural design of portable charging equipment is often concentrated at the end or edge of the chassis to adjust the chassis height to match the frame height of the transport vehicle, enabling the loading and unloading of the equipment. However, this layout has obvious drawbacks: Firstly, if the lifting mechanism is located at the end of the chassis on the side where the battery box is located, it will interfere with the positions of the charging and discharging guns on the battery box. When inserting or removing the guns, one must avoid the structural components of the lifting mechanism, which limits the operating space, reduces the efficiency of insertion and removal, and is prone to damage to the guns or the lifting mechanism due to improper operation. Secondly, some lifting mechanisms are large in size to ensure support stability, and the edge arrangement will occupy the effective space around the chassis, resulting in insufficient compactness of the battery box and the charging box, affecting the overall size optimization of the equipment and hindering the flexible transportation and storage of the equipment. In addition, the structural layout of existing charging equipment often fails to balance lifting function and ease of use. While pursuing support stability, it neglects the convenience of daily operation, making it difficult to meet the high-efficiency use needs in outdoor high-frequency charging scenarios.

[0018] It should be noted that these figures and text descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the invention, but are not intended to limit the scope of the invention.

[0020] In the description of the invention, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0021] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the invention based on the specific circumstances.

[0022] Example 1 like Figures 1 to 12As shown in the figure, this application embodiment provides a charging device 100, including: a chassis 1, multiple battery boxes 2, an electrical box 5, and a lifting mechanism. Each of the battery boxes 2 is disposed on the chassis 1. The electrical box 5 is disposed on the chassis 1, located on one side of each battery box 2 along the extending direction of the chassis 1. The electrical box 5 is electrically connected to the battery boxes 2 and is used for charging and / or discharging the battery boxes 2. The electrical box 5 is connected to a charging port, which is used to connect to an external device to charge the external device or to charge the battery box 2. The charging port and the body of the electrical box 5 can be plugged in and unplugged to fix the charging port and prevent it from falling off. The lifting mechanism is disposed on the chassis 1, partly between the battery boxes 2 and the electrical box 5, and partly on the side of the battery box 2 opposite to the electrical box 5. The lifting mechanism moves up and down, adjusting the height of the chassis 1.

[0023] This application optimizes the layout of the lifting mechanism, placing part of it between the battery box 2 and the electrical box 5, and part of it on the side of the battery box 2 away from the electrical box 5. This eliminates the previous method of centrally arranging the lifting mechanism at the end and head of the chassis 1, effectively avoiding the insertion and removal area of ​​the electrical box 5's plug-in gun. This provides ample space for plug-in gun operation, allowing operators to complete plug-in and removal without having to avoid the lifting mechanism components. This significantly improves the convenience and efficiency of charging and discharging operations, while reducing the risk of collision damage to the plug-in gun and lifting mechanism during operation, and extending the service life of the equipment.

[0024] In this application, the distributed layout of the lifting mechanism makes full use of the unused space between the battery box 2 and the electrical box 5, avoiding excessive occupation of the edge space of the chassis 1, and making the layout of the battery box 2, electrical box 5 and the lifting mechanism more compact and reasonable. Under the premise of ensuring the normal functioning of each component, the overall size of the equipment can be further optimized, while reducing the space occupied when the equipment is stored.

[0025] In some possible implementations, the electrical box 5 can be any of a charger, a discharger, or a charge-discharge integrated unit. The electrical box 5 facilitates the charging of electric machinery, which can be new energy vehicles such as heavy-duty trucks and mining trucks. Alternatively, the electrical box 5 can facilitate connection to a power source (charging station) to charge the battery box 2.

[0026] In some possible implementations, the charging device 100 includes a plurality of side-moving arms 3, and the lifting mechanism includes a plurality of lifting columns 4. Some of the side-moving arms 3 are disposed on the chassis 1 between the battery box 2 and the electrical box 5, and some of the side-moving arms 3 are disposed on the chassis 1 on the side of the battery box 2 opposite to the electrical box 5. The side-moving arms 3 are capable of telescopic movement along the width direction of the chassis 1. The lifting columns 4 are at least partially located above the chassis 1 and are disposed on the side-moving arms 3. The lifting columns 4 are capable of extending downward toward the chassis 1 or retracting upward toward the side of the chassis 1.

[0027] The chassis 1 of the charging device 100 of this application can be narrower than the frame 210 of the vehicle 200. When the charging device 100 needs to be transported, its side sliding arm 3 and lifting column 4 are both in an extended state. The distance between the lifting columns 4 on both sides of the chassis 1 along the width direction is large, so that the frame 210 of the vehicle 200 can smoothly enter under the chassis 1. Then the lifting column 4 retracts, the chassis 1 is supported on the frame 210, and the side sliding arm 3 retracts so that the entire charging device 100 is located inside the upper surface of the frame 210 and does not protrude from the frame 210, which meets the safety transportation requirements of the vehicle 200 and does not require an overweight transportation permit. When the vehicle 200 transports the small charging device 100, it has good passability and high safety.

[0028] In some possible implementations, the lifting column 4 includes a fixed cylinder 41 and a movable support leg 42. The fixed cylinder 41 is located on the upper side of the chassis 1, and the bottom of the fixed cylinder 41 is connected to the side shift arm 3. The movable support leg 42 is slidably connected to the fixed cylinder 41 and can extend downward or retract into the fixed cylinder 41.

[0029] The fixed cylinder 41 can be perpendicular to the side-shifting arm 3. The bottom of the fixed cylinder 41 is connected to the side-shifting arm 3. The movable support leg 42 is slidably connected to the fixed cylinder 41. The movable support leg 42 can extend towards the bottom side of the fixed cylinder 41 or retract towards the fixed cylinder 41. In the transportation state, the movable support leg 42 of the charging device located on the frame retracts upward, and the distance between the movable support leg 42 and the ground is large, avoiding interference with the outside environment. Furthermore, in the transportation state, when the side-shifting arm 3 retracts, it moves the entire lifting column 4 to the inside of the upper surface of the frame 210. The bottom of the movable support leg 42 is higher than the frame 210, so it will not interfere with the frame 210 or protrude from the frame boundary, improving safety.

[0030] In some possible implementations, the charging device 100 includes a telescopic tank 12 disposed on the chassis 1 and extending along the width direction of the chassis 1. The side-moving arm 3 includes a telescopic cylinder 31 and two main arms 32, both of which are slidably disposed on the telescopic tank 12. The telescopic cylinder 31 is located inside the telescopic tank 12 and between the two main arms 32. The two ends of the telescopic cylinder 31 are respectively connected to the two main arms 32. The telescopic cylinder 31 can extend or retract, thereby driving the two main arms 32 to extend or retract from the telescopic tank 12.

[0031] The chassis 1 includes a chassis body 11. A telescopic storage tank 12 is located on the side of the chassis 1 where the battery box 2 is located, i.e., on the top of the chassis 1. A side-moving arm 3 is telescopically mounted on the telescopic storage tank 12. The telescopic storage tank 12 being located on the top of the chassis 1 helps to increase the height of the side-moving arm 3, ensuring that after the movable outrigger 42 retracts to its limit position, the lower edge of the entire lifting column 4 is not lower than the chassis 1. After the side-moving arm 3 retracts, the bottom of the lifting column 4 will not interfere with the frame 210. The telescopic storage tank 12 can be used to mount the side-moving arm 3 and also serves as the main crossbeam of the chassis 1, thereby enhancing the structural strength of the chassis 1.

[0032] In some possible implementations, the telescopic cylinder 31 includes a cylinder barrel and a movable rod, the movable rod being slidably connected to the cylinder barrel, and the movable rod and the cylinder barrel being respectively connected to the two main arms 32.

[0033] In this application, the telescopic cylinder 31 can be a floating cylinder. The telescopic movement of one floating cylinder can simultaneously drive the two main arms 32 to extend or retract from the chassis 1. One floating cylinder can replace two ordinary cylinders, simplifying the structure and reducing costs.

[0034] This application optimizes the side-shift drive structure to further reduce costs and increase efficiency: by adopting a floating cylinder as the telescopic cylinder 31, and with the structural design of "cylinder + movable rod", one floating cylinder can drive two main booms 32 to extend and retract simultaneously. There is no need to configure a separate ordinary cylinder for each main boom 32. This not only reduces the number of components such as cylinders, pipelines, and control valves, simplifying the overall structure of the side-shift drive system and reducing the cost of component procurement and assembly, but also reduces the complexity of pipeline layout, reduces the risk of hydraulic system leakage and failure, improves the reliability of the side-shift mechanism, and reduces the workload and cost of later maintenance.

[0035] In some possible implementations, such as Figure 5 As shown, the inner wall of the telescopic barrel 12 is provided with a first slider group 122, and the outer wall of the main arm 32 of the side-moving arm 3 is provided with a second slider group 321. The first slider group 122 and the outer surface of the main arm 32 are slidably engaged, and the second slider group 321 and the inner wall of the telescopic barrel 12 are slidably engaged.

[0036] In some possible implementations, the main boom 32 has a cavity and an operating port 323 communicating with the cavity. A connecting seat 324 is provided inside the main boom 32, the connecting seat 324 being exposed to the operating port 323. A cylinder or movable rod extends into the cavity and is connected to the connecting seat 324.

[0037] In this implementation scheme, by opening an operating port 323 on the main boom 32, the assembly of the telescopic cylinder 31 and the connecting seat 324 can be facilitated. For example, as Figure 5 and Figure 6As shown, the connecting seat 324 may include two plates spaced apart. The two plates are arranged in sequence at intervals along the opening direction of the operating port 323. One end of the telescopic cylinder 31 can be inserted between the two plates, and then a connecting piece (such as a bolt or pin) can be used to connect and fix the telescopic cylinder 31 and the two plates.

[0038] In some possible implementations, such as Figure 5 As shown, a limiting member 123 is provided on the telescopic barrel 12, protruding into the telescopic barrel. Two limiting fitting members 322 are provided on the main arm 32, spaced apart along the length of the main arm 32. The limiting member 123 is located between the two limiting fitting members 322. When the telescopic cylinder 31 extends to its limit state, one limiting fitting member 322 abuts against the limiting member 123. When the telescopic cylinder 31 retracts to its limit state, the other limiting fitting member 322 abuts against the limiting member 123. The extension range of the main arm 32 can be limited by the two limiting members 123.

[0039] In some possible implementations, such as Figure 4 , Figure 7 and Figure 9 As shown, the charging device 100 includes a hydraulic pump station 6 and an auxiliary power supply 7. The hydraulic pump station 6 and the auxiliary power supply 7 are mounted on the chassis 1 and located on the side of the battery box 2 away from the battery box 5. The hydraulic pump station 6 is connected to the lifting mechanism through hydraulic pipelines, such as to the lifting column 4, or to the telescopic cylinder 31, to provide the movement power for the lifting column 4 and the telescopic cylinder 31. The auxiliary power supply 7 is electrically connected to the hydraulic pump station 6.

[0040] In some possible implementations, the hydraulic pump station 6 and auxiliary power supply 7 can be installed on top of the telescopic container 12, reducing the space occupied by the chassis body 11. A connecting beam 19 can be provided around the top edge of the chassis body 11, encompassing the web and flanges located on the upper and lower sides of the web. The bottom flanges are fitted and connected to the top wall of the telescopic container 12, and the hydraulic pump station 6 and auxiliary power supply 7 are connected to the top flanges via fasteners. The connecting beam 19 forms the top flanges, facilitating the support and fixation of the hydraulic pump station 6 and auxiliary power supply 7.

[0041] In some possible implementations, the electrical box 5 includes an electrical box body and a plug gun disposed on the electrical box body. The electrical box body is connected to the chassis 1, and the plug gun is disposed on the side of the electrical box body away from the side facing the battery box 2, which facilitates the operator to pick up and put down the plug gun and avoids the action of picking up and putting down the plug gun being affected by the battery box 2.

[0042] In some possible implementations, the charging device 100 includes at least two battery boxes 2 and at least two electrical boxes 5. The battery boxes 2 are arranged sequentially along the length of the chassis 1, while the electrical boxes 5 are located at one end of each of the battery boxes 2 and extend along the width of the chassis 1. Two side arms 3 are respectively located at opposite ends of the battery boxes 2 along their arrangement direction. One side arm 3 is located between the battery box 2 and the electrical box 5, and the other side arm 3 is located on the side of the battery box 2 facing away from the electrical box 5. The electrical boxes 5 are smaller than the battery boxes 2; therefore, the electrical boxes 5 can be arranged sequentially along the width of the chassis 1, making full use of the space on the chassis 1.

[0043] like Figure 7 As shown, a fixing seat 14 is provided along the edge of the chassis 1. The fixing seat 14 is used to connect and fix the chassis 1 to the frame 210 of the vehicle 200 when the chassis 1 is supported on the frame 210. For example, the fixing seat 14 forms a sleeve hole, through which a connector can pass to connect to the frame 210 and fix the chassis 1. Multiple fixing seats 14 are provided on both sides of the chassis 1 along the width direction, and the fixing seats 14 are arranged sequentially at intervals along the length direction of the chassis 1.

[0044] In some possible implementations, such as Figure 4 As shown, the chassis body 11 has a clearance notch 111 along its edge, and the bottom end of the lifting column 4 has a support leg 421. When the side arm 3 and the lifting column 4 are both retracted to their limit positions, the support leg 421 is located at the clearance notch 111. The support leg 421 does not protrude from the two sides of the chassis body 11 along its width direction. In the transport state, the entire lifting column 4 is located inside the frame 210 of the vehicle 200 and does not extend out of the frame 210.

[0045] In some possible implementations, such as Figure 7 and Figure 8 As shown, the chassis 1 includes a frame, a bottom guard plate 15, and a step plate 16. The bottom guard plate 15 and the step plate 16 are respectively disposed on both sides of the frame along the thickness direction. At least one of the bottom guard plate 15 and the step plate 16 is detachably connected to the frame, and a pipeline cavity 17 is formed between the bottom guard plate 15 and the step plate 16. The battery base and the electrical box 5 are both disposed on the frame. The battery base is connected to the electrical box 5 via a cable, and the cable is located in the pipeline cavity 17.

[0046] The charging device 100 of this application hides the cable connecting the battery base and the power box 5 inside the chassis 1, avoiding cable exposure and protecting the cable. It also makes the various structural components on the chassis 1 neat and orderly, improving product quality.

[0047] Example 2 like Figures 1 to 12As shown in the illustration, this application provides a mobile charging device 100, including: a chassis 1, a battery box 2, an electrical box 5, and multiple rotary locking assemblies 8. Each rotary locking assembly 8 is disposed on the chassis 1, and each rotary locking assembly 8 includes a rotary locking member and a handle 84. The rotary locking member is rotatably connected to the chassis 1, and the handle 84 is connected to the rotary locking member. When the battery box 2 is supported on the chassis 1, rotating the handle 84 can drive the rotary locking member to rotate, thereby locking or unlocking the battery box 2. The electrical box 5 is disposed on the chassis 1 and electrically connected to the battery box 2. The electrical box 5 is used for charging and / or discharging the battery box 2.

[0048] The electrical box 5 is connected to a charging port, which is used to connect to external devices for charging or to charge the battery box 2. The charging port and the main body of the electrical box 5 are pluggable and detachable to secure the charging port and prevent it from falling out.

[0049] This application uses a manual rotary lock assembly 8 to replace the electric drive locking mechanism, eliminating the need for components such as motors and control circuits. This reduces the number of parts, shrinks the size and weight of the equipment, saves on the procurement and assembly costs of the electric drive assembly, significantly reduces the production cost of the equipment, and facilitates the market promotion of the product. The manual locking mechanism is less affected by environmental factors and is less prone to failure in harsh environments such as low temperature and humidity. Moreover, it is simple to operate and can smoothly complete the disassembly and replacement of the battery box 2.

[0050] In some possible implementations, the rotary lock assembly 8 further includes a fixing body 81 disposed on the top of the chassis 1. The fixing body 81 has a rotating groove. The rotary lock includes a rotating shaft 82 and a locking tongue 83. The rotating shaft 82 is rotatably disposed in the rotating groove and can move along the axis of the rotating groove. The locking tongue 83 is disposed on the rotating shaft 82. A handle 84 is connected to the rotating shaft 82. Rotating the handle 84 can drive the rotating shaft 82 to rotate, thereby locking or unlocking the battery box 2 with the locking tongue 83.

[0051] The end of the fixing body 81 is provided with a locking limiting notch, which connects to the rotating groove. When the latch 83 is locking the battery compartment 2, the rotating shaft 82 rotates until the latch 83 engages with the locking limiting notch. When the latch 83 is unlocking the battery compartment 2, the rotating shaft 82 rotates until the latch 83 disengages from the locking limiting notch. Specifically, when locking the battery compartment 2, a person holding the handle 84 applies upward force to disengage the latch 83 from the locking limiting notch, and then rotating the handle 84 disengages the latch 83 from the battery compartment 2.

[0052] The end of the fixed body 81 may also be provided with an unlocking limit notch. The unlocking limit notch is connected to the rotating groove. When the lock tongue 83 unlocks the battery box 2, the rotating shaft 82 rotates until the lock tongue 83 is engaged in the unlocking limit notch, thus preventing the rotating shaft 82 from rotating accidentally.

[0053] In some possible implementations, a support plate 811 is provided on the outer wall of the fixing body 81, and the support plate 811 elastically contacts the battery box 2 when the battery box 2 is seated on the chassis 1.

[0054] A bottom beam is provided on the inner wall of the bottom opening of the battery box 2. When the rotary lock locks the battery box 2, its locking tongue 83 rotates to be limited to the upper surface of the bottom beam. At the same time, the support plate 811 elastically abuts against the bottom beam, thereby eliminating the play between the battery box 2 and the fixed body 81, so that the battery box 2 and the rotary lock assembly 8 fit tightly together, avoiding or reducing the shaking of the battery box 2.

[0055] In some possible implementations, an observation port 2a is provided on the skin of the battery box 2, which is connected to the inner cavity at the bottom of the battery box 2, so that the state of the locking tongue 83 can be directly observed, and it is convenient to determine whether the locking tongue is locked or unlocked.

[0056] In some possible implementations, the chassis 1 has an inner cavity, the fixing body 81 and the locking tongue 83 are located on the top of the chassis 1, and the handle 84 is located in the inner cavity. The handle 84 is hidden in the inner cavity to avoid being exposed to the outside, which would make it easy to interfere with the external structure or be misoperated, thus improving safety.

[0057] This application designs the chassis 1 as a structure with an inner cavity, hiding the handle 84 inside the inner cavity. The rotary locking component is at least partially located on the top of the chassis 1, which can effectively prevent the handle 84 from being exposed to the outside and interfering with the external structure. At the same time, it prevents accidental operation from causing abnormal locking status, further enhancing the safety and stability of the equipment during use and adapting to the usage needs of complex outdoor operation scenarios.

[0058] In some possible implementations, such as Figure 2 and Figure 3 As shown, side openings 113 are provided on the end faces of both sides of the chassis 1 along the width direction. The side openings 113 communicate with the inner cavity, and part of the handle 84 of the rotary locking assembly 8 is exposed in the side openings 113. The side openings 113 facilitate the operator to reach into the inner cavity to grasp and operate the handle 84.

[0059] In this application, the chassis 1 is equipped with an inner cavity and side openings 113, balancing safety and convenience while optimizing the user experience. The handle 84 is concealed within the inner cavity of the chassis 1, physically preventing interference and misoperation issues caused by the exposed handle 84, thus improving safety. Simultaneously, side openings 113 connecting to the inner cavity are provided on both ends of the chassis 1 in the width direction, partially exposing the handle 84. This allows operators to quickly reach and grasp the handle 84 to complete operations without additional disassembly, balancing safety and ease of operation, and meeting the needs of efficient outdoor operations. The combination of the concealed handle 84 and side openings 113 allows for adjustments to the position and size of the side openings 113 and the number of rotary locking components 8 to suit different battery box specifications 2 and outdoor operating scenarios, further expanding the application range of the equipment.

[0060] In some possible implementations, the chassis 1 includes a frame, a bottom guard plate 15, and a step plate 16, the bottom guard plate 15 and the step plate 16 being disposed on both sides of the frame along the thickness direction, the step plate 16 being detachably connected to the frame, and the inner cavity being formed between the bottom guard plate 15 and the step plate 16.

[0061] For handles 84 that are not exposed in the side opening 113, the inner cavity can be partially exposed by removing the foot plate 16 at the corresponding position, making it easier to insert the arm into the inner cavity and rotate the corresponding handle 84.

[0062] In some possible implementations, such as Figure 10 As shown, the frame includes multiple crisscrossing beams, each beam enclosing multiple partitioned areas 114. Each step plate 16 covers a corresponding partitioned area 114. The step plates 16 are designed for workers to step on, facilitating movement during maintenance. Supporting ribs 18 are provided on some beams, and the step plates 16 are supported on these ribs. The upper surfaces of the beams and step plates 16 can be approximately on the same plane to avoid creating obstacles and facilitate movement of maintenance personnel on the chassis 1.

[0063] In some possible implementations, the step plate 16 has a front panel 161 and an edge plate 162. The edge plate 162 is located at the edge of the front panel 161 and extends along the thickness direction of the front panel 161. A bent edge 1621 is provided at the end of the edge plate 162 away from the front panel 161. The bent edge 1621 has a connecting hole 16211 and is fitted to the support rib plate 18. Fasteners pass through the support rib plate 18 and the connecting hole 16211 to fix the bent edge 1621 to the support rib plate 18. A threaded groove may be provided on the support rib plate 18. The fastener may be a screw, with the stud of the screw threaded into the threaded groove through the connecting hole 16211. The nut at the end of the screw is confined to the bent edge 1621.

[0064] In some possible implementations, the panel 161 is provided with a disassembly hole 1611, and the projection of the connecting hole 16211 onto the panel 161 falls into the disassembly hole 1611. An operator can use a disassembly tool to pass through the disassembly hole 1611 and apply it to the nut; rotating the tool will loosen the nut, thus performing the disassembly / reassembly operation of the footplate 16. The disassembly tool can be a screwdriver.

[0065] In some possible implementations, the chassis 1 is provided with multiple guide posts 20, and the battery box 2 is provided with guide mating holes. When the battery box 2 is installed on the chassis 1, the guide posts 20 pass through the guide mating holes. The guide posts 20 have the function of guiding and positioning the battery box 2, assisting the battery box 2 to be accurately seated on the chassis 1.

[0066] In some possible implementations, the mobile charging device 100 includes a plurality of pads 21, each of which is disposed on the upper surface of the chassis 1. When the battery box 2 is seated on the chassis 1, the battery box 2 is supported on each of the pads 21. The pads 21 serve to support the battery box 2 and prevent the battery box 2 from directly contacting the chassis 1.

[0067] In some possible implementations, the top of the chassis 1 has a clearance opening 112 communicating with the inner cavity of the chassis 1. With the battery box 2 seated on the chassis 1, the battery box 2 covers the clearance opening 112. The battery box 2 and the electrical box 5 are connected by a cable, with part of the cable located in the inner cavity and part extending out of the clearance opening 112 to connect with the battery box 2. In this application, it is not necessary to provide an electrical connector on the chassis 1 to achieve the transfer between the electrical box 5 and the battery box 2; instead, the cable is directly connected to the bottom of the battery box 2 to achieve the electrical connection between the battery box 2 and the electrical box 5, simplifying the connection structure.

[0068] Example 3 In some possible implementations, embodiments of this application provide a charging system including: a vehicle 200 and the aforementioned charging device 100. The vehicle 200 has a frame 210 and a front end connected to the frame 210. With the charging device 100 mounted on the frame 210, the electrical box 5 is located at the end of the battery box 2 facing away from the front end. The electrical box 5 is located at the rear of the vehicle 200, facilitating the insertion and removal of the charging plug. The charging system may include at least two of the aforementioned charging devices 100 and at least one vehicle 200, and the number of vehicles 200 may be less than the number of charging devices 100. The vehicle 200 has a frame 210. In the transport preparation state, the vehicle 200 can drive to a position where the frame 210 is located at the bottom of the chassis 1 of the charging device 100. In the transport state, the movable support leg 42 retracts, the side sliding arm 3 retracts, the chassis 1 of the charging device 100 is supported on the frame 210, and the lifting column 4 is entirely located on top of the frame 210. During the transportation of the charging equipment 100 by vehicle 200, the rising column 4 will not interfere with the external structure, thus improving the passability and safety of vehicle 200.

[0069] The number of vehicles 200 is less than the number of charging devices 100. After transporting the charging device 100 to the target location, the vehicle 200 can unload the charging device 100. One vehicle 200 can correspond to multiple charging devices 100. The vehicle 200 can sequentially transport different charging devices 100 according to actual needs. This one-to-many cooperation method helps to save the number of vehicles 200 and reduce operating costs. After the vehicle 200 transports the charging device 100 to the target location, the side arm 3 of the charging device 100 can be extended, and the lifting column 4 can be extended to support the ground, so that the chassis 1 is higher than the frame 210 of the vehicle 200. At this time, the vehicle 200 can drive out of the charging device 100 to continue to perform other tasks, and the charging device 100 can be temporarily placed at the target location for charging services for a period of time.
