Technical Field

[0001] This utility model relates to the field of charging system technology, and more specifically, to a charging device and a charging system. Background Technology

[0002] After a vessel with a depleted battery docks, the dock's tower crane lifts the power supply unit from the electric vessel onto a transport vehicle on the shore and transports it to the battery swapping station. A front-end crane then lifts the power supply unit from the transport vehicle and places it at the charging station for charging. During charging, the thick and heavy charging cable needs to be manually dragged and inserted into the charging station. Due to the weight of the cable, two people are required to insert and remove the charging cable together.

[0003] In related technologies, during the process of dragging the gun wire, the gun wire rubs against the ground, resulting in high resistance, making dragging difficult, and easily causing wear and tear on the gun wire. Utility Model Content

Therefore, one objective of this invention is to provide a charging device and charging system, wherein the charging device can transform the sliding friction between the power transmission cable and the ground into rolling friction, reducing the resistance experienced by the power transmission cable, reducing the difficulty of movement of the power transmission cable, and also helping to reduce the wear and tear on the power transmission cable and extend its service life.

[0005] A charging device according to an embodiment of the present invention includes: a charging plug assembly, the charging plug assembly including a charging connector for plugging into the charging port of an external device; a power transmission cable, the tail end of the charging connector being connected to the power transmission cable; and a first support assembly, the first support assembly including a support member and a support wheel, the power transmission cable being mounted on the support member, and the support wheel being disposed on the support member and used for supporting movement on a walking surface.

[0006] According to the charging device of this utility model embodiment, the power transmission cable is stably supported by the support member in the first support assembly, and the sliding friction between the power transmission cable and the running surface is transformed into rolling friction by the support wheel in the first support assembly. This helps to reduce the resistance encountered by the power transmission cable and the charging plug assembly during movement, which can both accelerate the movement speed of the power transmission cable and the charging plug assembly and improve the movement accuracy of the charging plug assembly. This improves the charging efficiency and charging accuracy of the charging device for external devices such as box-type power supplies, and also helps to reduce the wear of the power transmission cable to extend its service life, thereby improving the service life of the charging device. It is also economical.

[0007] In addition, the charging device according to the above embodiments of the present invention may also have the following additional technical features: According to some embodiments of the present invention, the charging plug assembly includes a plurality of charging connectors, the plurality of charging connectors are connected to a plurality of power transmission cables, the support member includes a plurality of support portions, the plurality of power transmission cables are connected to the plurality of support portions, and the plurality of support portions are integrally connected.

[0008] In the above technical solution, multiple support parts are connected as a whole, which facilitates the unified movement of multiple power transmission cables and makes it less likely for multiple power transmission cables to interfere with each other, such as entanglement or friction. This helps to improve the working reliability, stability and safety of multiple power transmission cables, and also facilitates the subsequent maintenance and repair of multiple power transmission cables.

[0009] According to some embodiments of the present invention, the first support component includes at least two support wheels, and a plurality of support parts are integrally connected to at least two support wheels.

[0010] In the above technical solution, by connecting multiple support parts into one unit through at least two support wheels, the load of multiple support parts can be distributed to form a more stable support structure, making the movement of multiple support parts more stable and less prone to shaking or even tipping over, which is conducive to improving the working stability of multiple power transmission cables on multiple support parts.

[0011] According to some embodiments of the present invention, the charging connector is inserted into the charging port along a first direction, a plurality of power transmission cables are arranged along a second direction, the second direction intersects with the first direction, and a plurality of support portions of the same first support component are arranged at intervals along the second direction.

[0012] In the above technical solution, by arranging multiple power transmission cables along the second direction and arranging multiple support parts of the same first support component at intervals along the second direction, the structural compactness of the charging device can be improved and the risk of mutual interference between multiple power transmission cables can be reduced. It also reduces the assembly difficulty of the first support component and makes installation convenient.

[0013] According to some embodiments of the present invention, the support member further includes a base plate, the support wheel is disposed on the lower side of the base plate, and a plurality of the support parts are disposed on the upper side of the base plate.

[0014] In the above technical solution, the base plate can raise the power transmission cable, completely separating the power transmission cable from the walking surface, reducing the possibility of wear caused by friction between the power transmission cable and the walking surface, which helps to protect the power transmission cable and extend its service life.

[0015] According to some embodiments of the present invention, the support portion includes a first fastening portion and a second fastening portion. The first fastening portion is disposed on the base plate, and the second fastening portion fastens with the first fastening portion and defines a through hole for passing through the power transmission cable.

[0016] In the above technical solution, the assembly difficulty of the support part and the installation difficulty of the power transmission cable at the support part can be reduced by the first fastening part and the second fastening part, which facilitates assembly.

[0017] According to some embodiments of the present invention, there are multiple first support components, and the multiple first support components are spaced apart along the extension direction of the power transmission cable.

[0018] In the above technical solution, by arranging multiple first support components spaced apart along the extension direction of the power transmission cable, different areas of the power transmission cable can be stably kept apart from the running surface. In particular, it can meet the support and running requirements of long power transmission cables, and can also improve the movement flexibility of different parts of the power transmission cable supported on multiple first support components. This helps to reduce the resistance encountered by the power transmission cable and the charging plug assembly during movement, thereby improving the charging efficiency and charging accuracy of the charging device for the box-type power supply.

[0019] According to some embodiments of the present invention, the charging device further includes a charging base, the charging plug assembly is movably mounted on the charging base, the power transmission cable includes a first segment, a second segment and a third segment, the first segment is located on the lower side of the charging base and supported on the walking surface by the first support component, the second segment is located on the upper side of the charging base and mounted on the charging plug assembly, and the third segment is bent and extended to connect the first segment and the second segment.

[0020] In the above technical solution, the deformation of the third segment can accommodate the relative movement of the first and second segments in any direction in three-dimensional space, thereby reducing the resistance encountered by the power transmission cable and the charging plug assembly during movement, reducing the overall movement amplitude of the power transmission cable, and improving the stability of the charging device.

[0021] According to some embodiments of the present invention, the charging device further includes: a second support component, the second support component being mounted on the charging plug assembly, and the second support component including a first rolling element, the first rolling element rotatably supporting the power transmission cable, the power transmission cable extending sequentially along the arrangement direction of the first support component, the second support component and the charging connector.

[0022] In the above technical solution, the first rolling element rolls and supports the power transmission cable, which can reduce the sliding friction between the power transmission cable and the charging plug assembly by rotating the rolling friction. This helps to reduce the resistance encountered when the power transmission cable and the charging plug assembly move relative to each other. It can both accelerate the movement speed of the power transmission cable and the charging plug assembly and improve the movement accuracy of the charging plug assembly, thereby improving the charging efficiency and accuracy of the charging device for the box-type power supply. It also helps to reduce the wear of the power transmission cable and extend its service life, thereby improving the service life of the charging device. It is economical.

[0023] According to some embodiments of the present invention, the second support component further includes a second rolling element, which is arranged at a distance from the first rolling element. The power transmission cable is movably located between the first rolling element and the second rolling element, and the second rolling element rolls in cooperation with the power transmission cable.

[0024] In the above technical solution, the first and second rolling elements can limit the power transmission cable, making it difficult for the power transmission cable to separate from the charging plug assembly. The limiting effect is good. Furthermore, the second rolling element is rolled to the power transmission cable, which helps to reduce the resistance encountered by the power transmission cable when it moves relative to the charging plug assembly, thereby improving the charging efficiency and charging accuracy of the charging device for the box-type power supply.

[0025] According to some embodiments of the present invention, in at least one of the second support components, one of the first rolling element and the second rolling element is a roller, and the outer peripheral surface of the roller is provided with an annular groove extending circumferentially along the roller, and the power transmission cable is located in the annular groove.

[0026] In the above technical solution, the annular groove can limit the movement of the power transmission cable, preventing it from moving significantly along the rolling axis of the roller. This allows the power transmission cable to move as far as possible along its own extension direction at the second support component, reducing relative movement between the power transmission cable and its output charging connector, thus improving the connection stability between the power transmission cable and the charging connector. It also facilitates the connection of the power transmission cable to the power supply via the charging connector of the charging assembly, reducing the risk of misalignment between the charging connector at the power transmission cable's output end and the charging panel of the power supply, thereby improving the charging accuracy of the charging device for the power supply.

[0027] According to some embodiments of the present invention, there are multiple power transmission cables, multiple rollers that correspond one-to-one with the multiple power transmission cables, and the second support component further includes a support shaft and a spacer. The multiple rollers and the spacer are all sleeved on the support shaft, and adjacent rollers are abutted and limited by the spacer.

[0028] In the above technical solution, the spacers between multiple rollers and adjacent rollers can prevent the rollers from interfering with each other, which helps to reduce the possibility of interference such as entanglement and friction between different power transmission cables, thus extending the service life of the power transmission cables and improving their operational reliability, stability and safety.

[0029] According to some embodiments of the present invention, in at least one of the second support components, the first rolling element and the other of the second rolling element are rotating rods, and there are multiple rollers. The outer peripheral surface of the rotating rod stops at the groove of the annular groove of the multiple rollers.

[0030] In the above technical solution, the rotating rod can limit the power transmission cable within the annular groove, reducing the risk of the power transmission cable coming off the second support component. The rotating rod and the roller work together to prevent the power transmission cable from coming off, which helps to improve the stability of the connection between the power transmission cable and the charging plug assembly.

[0031] According to some embodiments of the present invention, the charging device further includes a charging base, and the charging plug-in assembly includes a first moving module. The first moving module is movably disposed on the charging base along a first direction. The first moving module is used to drive the charging connector to move relative to the charging base along the first direction to engage with the charging port. The first rolling element and the support wheel are movable along the first direction to allow the power transmission cable to move along the first direction.

[0032] In the above technical solution, during the process of the charging connector moving relative to the charging base along the first direction to engage with the charging port, the sliding friction between the power transmission cable and the running surface can be transformed into rolling friction, and the sliding friction between the power transmission cable and the charging plug assembly can be transformed into rolling friction. This helps to reduce the frictional resistance experienced by the charging connector and the power transmission cable during their movement, improves the efficiency of the charging connector engaging with the charging port, and thus improves the charging efficiency of the charging device for the box-type power supply.

[0033] According to some embodiments of the present invention, the charging plug assembly includes a second moving module, which is movably disposed on the first moving module along a second direction. The second moving module is used to drive the charging connector to move relative to the first moving module along the second direction, the second direction intersecting the first direction. At least one second support component is disposed on the second moving module and can move with the second moving module along the second direction. The support wheel can roll along the second direction.

[0034] In the above technical solution, the control accuracy of the moving displacement of the charging connector along the first and second directions can be improved by the first moving module and the second moving module, so as to improve the control accuracy of the position of the charging connector, so that the charging connector can be accurately electrically connected to the corresponding charging panel. The insertion and removal accuracy of the same charging connector with one charging panel or alternating with multiple charging panels is higher and the insertion and removal success rate is higher.

[0035] According to some embodiments of the present invention, the external device includes a plurality of charging panels, which are arranged sequentially along the second direction at one end of the external device facing the charging plug assembly. The charging plug assembly includes one unit, which is movable relative to the external device along the second direction to engage with any one of the plurality of charging panels.

[0036] In the above technical solution, a single charging plug assembly can meet the charging needs of external devices with multiple charging panels, reducing the cost of the charging device and improving its applicability.

[0037] According to some embodiments of the present invention, the charging plug-in assembly includes a third moving module, which is movably disposed on the second moving module in the vertical direction. The third moving module is used to drive the charging connector to move relative to the second moving module in the vertical direction. The first direction, the second direction, and the vertical direction intersect each other. At least one second support component is disposed on the third moving module and can move with the third moving module in the vertical direction.

[0038] In the above technical solution, the first, second, and third moving modules enable the charging connector to move along the first, second, and vertical directions with high precision. This improves the insertion accuracy between the charging connector and the corresponding charging panel, and also facilitates the alternating insertion of the same charging connector with different charging panels of the box-type power supply, meeting the charging needs of different circuits in the box-type power supply. Furthermore, both the second and third moving modules are equipped with at least one second support component, ensuring the cable moves stably with the second and third moving modules without slipping or violently shaking, thus improving the stability of the charging connector's movement along the first, second, and vertical directions.

[0039] According to some embodiments of the present invention, the second support assembly further includes a second rolling element, and the power transmission cable is movably located between the first rolling element and the second rolling element. In the second support assembly of the second moving module, one of the first rolling element and the second rolling element is a roller and the other is a rotating rod; in the second support assembly of the third moving module, both the first rolling element and the second rolling element are rotating rods.

[0040] In the above technical solution, the rollers and rotating rods of the second support component at the second moving module can limit the power transmission cable in the direction of the roller's rolling axis extension, such as the second direction, and in the arrangement direction of the first and second rolling elements, such as the up-down direction. The two rotating rods of the second support component at the third moving module can limit the power transmission cable in the arrangement direction of the first and second rolling elements, such as the up-down direction. The limiting effect on different parts of the power transmission cable is good.

[0041] According to some embodiments of this utility model, the support wheel is a swivel wheel.

[0042] In the above technical solution, by designing the support wheel as a swivel wheel, the movement flexibility of the support wheel can be improved, so as to realize the smooth movement of the power transmission cable in any direction at the swivel wheel. Moreover, the swivel wheel can turn freely in a limited space and can quickly respond to the movement of the power transmission cable. This helps to further reduce the resistance encountered by the power transmission cable and the charging plug assembly during the movement, thereby improving the charging efficiency and charging accuracy of the charging device for the box power supply.

[0043] Another objective of this invention is to provide a charging system having the aforementioned charging device.

[0044] A charging system according to an embodiment of the present invention includes a seating frame and a charging device according to an embodiment of the present invention, wherein the seating frame is connected to the charging device and the seating frame is used to place the external device.

[0045] In the above technical solution, the power transmission cable is stably supported by the support member in the first support assembly, and the sliding friction between the power transmission cable and the running surface is transformed into rolling friction by the support wheel in the first support assembly. This reduces the resistance encountered by the power transmission cable and the charging plug assembly during movement, which can both accelerate the movement speed of the power transmission cable and the charging plug assembly and improve the movement accuracy of the charging plug assembly. This improves the charging efficiency and accuracy of the charging device for the box-type power supply, and also reduces the wear of the power transmission cable, thus extending its service life and improving the service life of the charging device. It is also economical. Placing the box-type power supply on the seating frame shortens the time required to adjust its position, allowing for quick placement of the box-type power supply for charging by the charging device, thereby improving the charging efficiency of the box-type power supply.

[0046] According to some embodiments of the present invention, the charging system is used to charge a box-type power supply, which is a replaceable power supply for electric ships.

[0047] The above technical solutions enable electric vessels to swap batteries, reducing charging and swapping waiting time; and the box-type power supply can utilize the charging system for shore charging, which is not limited by the location of the electric vessel, making charging time more flexible, and improving the docking accuracy between the charging system and the box-type power supply.

[0056] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0057] In this application, "multiple" means two or more (including two).

[0058] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in aerospace and other fields. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0059] The box-type power supply mentioned in the embodiments of this application refers to a power supply device that integrates power-related equipment into a box. For example, the box-type power supply may include a containerized battery power supply, a boxed UPS power supply, a trolley box-type energy storage mobile power supply, an electrical box-type intelligent power supply, etc.

[0060] Containerized battery power refers to an energy storage system that integrates batteries within a container. It typically includes multiple battery modules, a battery management system (BMS), an energy conversion system, and related control and protection equipment. It boasts advantages such as modular design, high scalability, high energy density, and long lifespan, and is widely used in power systems, microgrids, and renewable energy generation systems.

[0061] Box-type power supplies can serve as an important component of backup power, peak-shaving power, or distributed energy systems, improving energy efficiency, reducing dependence on traditional energy sources, and mitigating environmental pollution. For example, in electric ships, box-type power supplies can provide power input to ensure normal navigation or serve as backup power to guarantee the ship's endurance and emergency response capabilities. In power systems, they can improve the reliability and stability of the power grid, ensuring the continuity of power supply.

[0062] The charging system is used to charge the energy storage system. Taking the ship charging scenario as an example, the shore-based charging system charges the ship's energy storage system (such as a box-type power supply). The charging system can be a fixed device, while the box-type power supply can be a mobile device. The box-type power supply is detachable, and after the ship docks, it can be disassembled by hoisting and then transported to the battery swapping station for charging by the charging system.

[0063] In related technologies, when using a charging system to charge a box-type power supply, the charging gun wire of the charging system is electrically connected to the box-type power supply to be charged. This requires manual dragging of the thick and heavy gun wire for manual charging. However, during the process of dragging the gun wire, the gun wire will slide and rub against the ground, which results in excessive resistance to the gun wire, making it too difficult to drag and easily causing wear and tear on the gun wire.

[0064] Based on this, this application proposes a charging device for a charging system. The charging device includes a charging plug assembly, a power transmission cable, and a first support assembly. The charging plug assembly includes a charging connector for plugging into the charging port of an external device, and the tail end of the charging connector is connected to the power transmission cable. The first support assembly includes a support member and a support wheel. The power transmission cable is mounted on the support member, and the support wheel is located on the support member and is used to support movement on a walking surface.

[0065] In the above embodiment, the power transmission cable is stably supported by the support member in the first support assembly, and the sliding friction between the power transmission cable and the running surface such as the ground is transformed into rolling friction by the support wheel in the first support assembly. This helps to reduce the resistance encountered by the power transmission cable and the charging plug assembly during movement, which can both accelerate the movement speed of the power transmission cable and the charging plug assembly and improve the movement accuracy of the charging plug assembly, thereby improving the charging efficiency and charging accuracy of the charging device for external devices. It also helps to reduce the wear of the power transmission cable and extend its service life, thereby improving the service life of the charging device, and has good economic benefits.

[0066] The charging device in this embodiment is used in a charging system, which can be used to charge external devices such as box-type power supplies. The external devices can be, but are not limited to, energy storage systems for electric ships, spacecraft, etc., where spacecraft can include airplanes, rockets, space shuttles, and spacecraft.

[0067] For ease of explanation, the following embodiments use an external device as a box-type power supply for electric ships as an example. The charging device of the charging system can be used to charge the box-type power supply of the electric ship.

[0068] Reference Figures 1-2 , Figure 1 and Figure 2 The diagram shows the charging system 1 and the box-type power supply 90 at different angles in some embodiments of this utility model. The electric ship has a box-type power supply 90, which is used to supply power to the electric ship.

The tail end of the charging connector 351 is connected to a power transmission cable 61 to supply power to the charging plug-in assembly 30 through the power transmission cable 61. For example, the charging connector 351 has two ends, the head end of the charging connector 351 is plugged into the charging port of the box-type power supply 90, and the tail end of the charging connector 351 is electrically connected to the power transmission cable 61.

The power transmission cable 61 is mounted on the support member 621, and the support wheel 622 is located on the support member 621 and is used to support the vehicle's movement on the walking surface.

[0072] The power transmission cable 61 is electrically connected to the charging connector 351 of the charging plug assembly 30. The power transmission cable 61 can also be electrically connected to a charging station, battery swapping station, smart charging pile, or other electrical storage device to charge the box-type power supply 90 via the power transmission cable 61 and the charging connector 351 of the charging plug assembly 30. For example, in some embodiments, such as... Figures 1-7 As shown, Figure 3 and Figure 4 This is a schematic diagram of the structure of the charging system 1 according to some embodiments of the present invention.

The output end of the power transmission cable 61 is electrically connected to the charging connectors 351, and the input end of the power transmission cable 61 can be electrically connected to the charging station to transmit the power from the charging station to the charging connectors 351 and then to the box-type power supply 90.

[0073] The power transmission cable 61 can be one, two, three, or more to meet the high-power charging requirements of the box-type power supply 90, for example... Figures 1-5 Three power transmission cables 61 are shown. The charging plug assembly 30 is used to organize one or more power transmission cables 61 together to allow one or more power transmission cables 61 to be simultaneously and detachably electrically connected to the box-type power supply 90. In some embodiments, such as Figures 1-7 As shown, the charging plug-in assembly 30 can also move to move the charging connector 351 along the first direction F1, the second direction F2, and the vertical direction F3 to change the position of the charging connector 351. This allows for more precise alignment of the charging connector 351 with the charging port of the charging panel 91, improving the insertion accuracy of the charging connector 351 with the charging port of the charging panel 91. It also facilitates significant adjustments to the position of the charging connector 351, allowing it to alternately connect with different charging panels 91 of the box power supply 90 to meet the charging needs of different circuits in the box power supply 90. The first direction F1, the second direction F2, and the vertical direction F3 intersect each other, and the vertical direction F3 can be parallel to the vertical direction or at a certain angle relative to the vertical direction.

[0074] During the connection process between the charging plug assembly 30 and the power supply box 90, the charging plug assembly 30 needs to be close to the power supply box 90; during the separation process, the charging plug assembly 30 needs to move away from the power supply box 90. Therefore, the charging plug assembly 30 and the power supply box 90 will move relative to each other, which in turn will cause the power transmission cable 61 to move relative to the power supply box 90. During the charging process of the power supply box 90, the power supply box 90 is usually kept stationary relative to the running surface such as the ground, and the charging plug assembly 30 is moved to move closer to or away from the power supply box 90. Therefore, the power transmission cable 61 will move relative to the running surface. However, the power transmission cable 61 is usually heavy. When the power transmission cable 61 is placed on the walking surface, the contact area with the walking surface is large. During the movement of the power transmission cable 61, sliding friction will occur with the walking surface, which will increase the movement resistance. The movement resistance of the charging plug assembly 30 will also increase, making it difficult for the charging plug assembly 30 to approach or move away from the box power supply 90. In addition, the power transmission cable 61 is easy to wear or even wear out, resulting in poor economic efficiency.

[0075] However, this application uses the first support component 62 to support the power transmission cable 61, which reduces the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during movement, and eliminates the need for manual dragging of the power transmission cable 61, saving manpower. Specifically, by using the support component 621 to stably install the power transmission cable 61, the possibility of the power transmission cable 61 slipping off the first support component 62 can be reduced, improving the support stability of the first support component 62 for the power transmission cable 61.

[0076] The support wheel 622 transforms the sliding friction between the power transmission cable 61 and the running surface into rolling friction, reducing the frictional force between the power transmission cable 61 and the running surface during movement. This reduces the resistance experienced by the power transmission cable 61 and the charging plug assembly 30 during movement, making it easier for the charging plug assembly 30 to approach or move away from the box-type power supply 90, thus improving the charging efficiency of the charging device 2 for the box-type power supply 90. The reduced movement resistance of the charging plug assembly 30 also facilitates precise control of its movement, such as displacement and angle, improving the accuracy of position adjustment. This allows the charging connector 351 of the charging plug assembly 30 to precisely connect to one charging panel 91 of the box-type power supply 90 or alternately connect to multiple charging panels 91, improving the charging accuracy of the charging device 2 for single-circuit and multi-circuit box-type power supplies 90. The sliding friction between the power transmission cable 61 and the running surface is transformed into rolling friction, which helps to reduce the risk of wear or even damage to the power transmission cable 61, extend the service life of the power transmission cable 61, and has better economic benefits.

[0077] The first support component 62 can be one, two, three, four, or more to meet the support requirements of power transmission cables 61 of different sizes. For example... Figures 7-11 The first support assembly 62 shown consists of four components. In each first support assembly 62, there can be one, two, or more support members 621 and support wheels 622, for example... Figures 7-11 In each of the first support components 62 shown, there is one support member 621 and two support wheels 622. Figure 8 , Figure 9 and Figure 10 This is a schematic diagram of a portion of the structure of the charging device 2 in some embodiments of the present invention. Figure 11 for Figure 10 A sectional view.

[0078] Thus, according to the embodiment of the present invention, the charging device 2 stably supports the power transmission cable 61 through the support member 621 in the first support component 62, and transforms the sliding friction between the power transmission cable 61 and the traveling surface into rolling friction through the support wheel 622 in the first support component 62. This helps to reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during movement, which can both accelerate the movement speed of the power transmission cable 61 and the charging plug assembly 30 and improve the movement accuracy of the charging plug assembly 30. This improves the charging efficiency and charging accuracy of the charging device 2 for external devices such as the box-type power supply 90, and also helps to reduce the wear of the power transmission cable 61 to extend its service life, thereby improving the service life of the charging device 2. It is also economical.

[0079] In some embodiments of this utility model, such as Figures 4-11 As shown, the charging plug-in assembly 30 includes a plurality of charging connectors 351, which are connected to a plurality of power transmission cables 61. Each charging connector 351 can be connected to one or more power transmission cables 61, and each power transmission cable 61 can be connected to one or more charging connectors 351. The support member 621 includes a plurality of support portions 6212, to which the plurality of power transmission cables 61 are connected. Each power transmission cable 61 can be connected to one or more support portions 6212, and each support portion 6212 can be connected to one or more power transmission cables 61. For example, in some embodiments, such as Figures 7-11 As shown, the charging plug-in assembly 30 includes three charging connectors 351, each charging connector 351 being connected to a power transmission cable 61, thus connecting the three charging connectors 351 to the three power transmission cables 61. At each first support assembly 62, the support member 621 includes three support portions 6212, each power transmission cable 61 being connected to one support portion 6212, thus connecting the three power transmission cables 61 to the three support portions 6212.

[0080] Multiple support parts 6212 are integrally connected, so that the multiple support parts 6212 at each first support component 62 are connected as a whole, so that the multiple power transmission cables 61 supported by the multiple support parts 6212 can be fixed as a whole. This integral connection of the multiple support parts 6212 facilitates the unified movement of the multiple power transmission cables 61, reduces interference between the multiple power transmission cables 61 (such as tangling or friction), improves the operational reliability, stability, and safety of the multiple power transmission cables 61, and also facilitates subsequent maintenance and repair of the multiple power transmission cables 61.

[0081] In some embodiments, such as Figures 7-11 As shown, the first support assembly 62 includes at least two support wheels 622, and multiple support parts 6212 are integrally connected to the at least two support wheels 622. By connecting the multiple support parts 6212 into one unit through at least two support wheels 622, the load of the multiple support parts 6212 can be distributed to form a more stable support structure, making the movement of the multiple support parts 6212 more stable and less prone to shaking or even tipping over, which is beneficial to improving the working stability of the multiple power transmission cables 61 on the multiple support parts 6212.

[0082] Multiple power transmission cables 61 may extend in a horizontal direction or in an oblique direction intersecting the horizontal direction. For example, in some embodiments, such as Figures 1-11 As shown, the charging connector 351 is plugged into the charging port along the first direction F1, and multiple power transmission cables 61 are arranged along the second direction F2. The second direction F2 intersects the first direction F1 (for example, the angle between the first direction F1 and the second direction F2 is an acute angle, a right angle, or an obtuse angle), making the multiple power transmission cables 61 arranged along the second direction F2 more compact, occupying less space, and easy to install.

[0083] Multiple support portions 6212 of the same first support component 62 are arranged at intervals along the second direction F2, which can increase the spacing between the power transmission cables 61 on adjacent support portions 6212, making the separation effect of adjacent power transmission cables 61 better, making adjacent power transmission cables 61 less likely to affect each other, and making it easier to install as there is less interference between adjacent support portions 6212 during the assembly of the first support component 62.

[0084] Therefore, by arranging multiple power transmission cables 61 along the second direction F2 and arranging multiple support parts 6212 of the same first support component 62 at intervals along the second direction F2, the structural compactness of the charging device 2 can be improved and the risk of mutual interference between multiple power transmission cables 61 can be reduced. It also reduces the assembly difficulty of the first support component 62 and makes installation convenient.

[0085] In some embodiments of this utility model, such as Figures 7-11As shown, the support member 621 also includes a base plate 6211, support wheels 622 are disposed on the lower side of the base plate 6211, and multiple support parts 6212 are disposed on the upper side of the base plate 6211. The base plate 6211 elevates the power transmission cable 61, completely separating it from the walking surface, reducing the possibility of wear caused by friction between the power transmission cable 61 and the walking surface. For example, in embodiments with multiple first support components 62, it reduces the risk of power transmission cables 61 between adjacent first support components 62 drooping onto the walking surface, thus protecting the power transmission cable 61 and extending its service life. In embodiments with multiple first support components 62, the number of first support components 62 can also be adjusted to adjust the spacing between adjacent first support components 62, making it less likely for power transmission cables 61 between adjacent first support components 62 to come into contact with the walking surface.

[0086] Multiple power transmission cables 61 can be fixed to multiple support parts 6212 one by one, so that the multiple power transmission cables 61 are less likely to interfere with each other, such as tangling or friction, which helps to improve the working reliability, stability and safety of the multiple power transmission cables 61, and also facilitates the subsequent maintenance and repair of the multiple power transmission cables 61.

[0087] Therefore, the base plate 6211 can raise the power transmission cable 61, completely separating the power transmission cable 61 from the running surface, reducing the possibility of wear caused by friction between the power transmission cable 61 and the running surface, which helps to protect the power transmission cable 61 and extend its service life.

[0088] In some embodiments, such as Figures 7-11 As shown, the support portion 6212 includes a first fastening portion 6213 and a second fastening portion 6214. The first fastening portion 6213 is disposed on the base plate 6211, and the second fastening portion 6214 is fastened to the first fastening portion 6213, defining a through hole for passing through the power transmission cable 61. The first fastening portion 6213 and the second fastening portion 6214 can be connected by bolts or other means. Through the through hole defined by the first fastening portion 6213 and the second fastening portion 6214, the first fastening portion 6213 and the second fastening portion 6214 can be fastened after the power transmission cable 61 is passed through the through hole position of the first fastening portion 6213. The installation of the first fastening portion 6213 and the second fastening portion 6214 is convenient and also facilitates the installation of the power transmission cable 61.

[0089] Therefore, by means of the first fastening part 6213 and the second fastening part 6214, the assembly difficulty of the support part 6212 and the installation difficulty of the power transmission cable 61 at the support part 6212 can be reduced, making assembly easier.

[0090] The power transmission cable 61 and the through hole can have a clearance fit, transition fit, interference fit, or other fits. For example, in some embodiments, such as... Figure 11 As shown, the interference fit between the power transmission cable 61 and the through hole can fix the power transmission cable 61 at the through hole, so that the power transmission cable 61 and the support part 6212 can move synchronously. This reduces the risk of sliding friction between the power transmission cable 61 and the support part 6212 due to relative movement, which helps to improve the reliability of the first support component 62 moving with the power transmission cable 61 and reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during movement.

[0091] In some embodiments of this utility model, such as Figures 7-11 As shown, there are multiple first support components 62, which are spaced apart along the extension direction of the power transmission cable 61. These multiple first support components 62 can support different portions of the power transmission cable 61 along its extension direction, ensuring that different areas of the power transmission cable 61 are stably separated from the running surface. This is particularly beneficial for supporting and navigating longer power transmission cables 61. Furthermore, the first support components 62 allow different portions of the power transmission cable 61 to move relative to the running surface, improving the flexibility of movement and reducing the resistance experienced by the power transmission cable 61 and the charging plug assembly 30 during movement. This enhances the charging efficiency and accuracy of the charging device 2 for the box-type power supply 90.

[0092] Therefore, by having multiple first support components 62 spaced apart along the extension direction of the power transmission cable 61, different areas of the power transmission cable 61 can be stably kept apart from the running surface. In particular, this can meet the support and running requirements of long power transmission cables 61, and also improve the movement flexibility of different parts of the power transmission cable 61 supported on multiple first support components 62. This helps to reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during movement, thereby improving the charging efficiency and charging accuracy of the charging device 2 for the box-type power supply 90.

[0093] In some embodiments, such as Figures 1-7 As shown, the charging device 2 also includes a charging base 10, on which the charging plug assembly 30 is movably mounted. The charging plug assembly 30 can be directly mounted to the charging base 10, reducing the number of components in the charging device 2 and thus achieving miniaturization. Alternatively, the charging plug assembly 30 can be indirectly mounted to the charging base 10 to meet other requirements. For example… Figures 1-7As shown, the charging device 2 also includes a movable platform 40 and a protective cover 50. For example, the protective cover 50 can protect against rain, sun, and dust. The charging plug assembly 30 is movably mounted on the movable platform 40 along the first direction F1. The movable platform 40 is movably mounted on the charging base 10 along the first direction F1. The protective cover 50 is mounted on the movable platform 40 and encloses the charging plug assembly 30. The protective cover 50 has two openable and closable interfaces, and a shield is provided at the interface. The shield can be made of rubber or other materials. The movable platform 40 moves along the first direction F1 closer to the box-type power supply 90 until the shield engages with the box-type power supply 90. Then, the charging plug assembly 30 moves along the first direction F1 closer to the box-type power supply 90, so that the charging connector 351 of the charging plug assembly 30 extends from either interface to be plugged into the corresponding charging panel 91 of the box-type power supply 90, thus meeting the rain protection requirements of the box-type power supply 90 during the charging process.

[0094] The power transmission cable 61 includes a first segment 611, a second segment 612, and a third segment 613. The first segment 611 is located on the lower side of the charging base 10 and is supported on the walking surface by the first support component 62. The second segment 612 is located on the upper side of the charging base 10 and is installed on the charging plug assembly 30. The third segment 613 is bent and extended to connect the first segment 611 and the second segment 612. The first segment 611, the second segment 612, and the third segment 613 refer to the fact that the overall shape of the power transmission cable 61 generally forms a U-shape and has the aforementioned positional arrangement with other structures of the charging device 2. During the movement of the charging plug assembly 30, the bending position of the power transmission cable 61 will change because the power transmission cable 61 needs to adapt to the movement of the charging plug assembly 30. That is, the position of the third segment 613 on the overall power transmission cable 61 will change rather than be fixed.

[0095] During the movement of the charging plug-in assembly 30, relative movement occurs between the first segment 611 and the second segment 612 of the power transmission cable 61. The bending deformation of the third segment 613 can accommodate this relative movement, thereby reducing the resistance experienced by the power transmission cable 61 during its movement and thus reducing the resistance experienced by the charging plug-in assembly 30. For example, as the first segment 611 and the second segment 612 move away from each other, the degree of bending of the third segment 613 decreases to approach straightness; as the first segment 611 and the second segment move closer to each other, the degree of bending of the third segment 613 increases.

[0096] Therefore, by deforming the third segment 613, it can adapt to the relative movement of the first segment 611 and the second segment 612 in any direction in three-dimensional space, so as to reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during the movement, reduce the overall movement amplitude of the power transmission cable 61, and improve the stability of the charging device 2.

[0097] In some embodiments of this utility model, such as Figures 5-11 As shown, the charging device 2 also includes a second support assembly 63, which is mounted on the charging plug assembly 30. The second support assembly 63 includes a first rolling element 631, which rolls and supports the power transmission cable 61, i.e., the first rolling element 631 is located below the power transmission cable 61. The power transmission cable 61 extends sequentially along the arrangement direction of the first support assembly 62, the second support assembly 63, and the charging connector 351, i.e., the power transmission cable 61 extends from the first support assembly 62 to the second support assembly 63, and from the second support assembly 63 to the charging connector 351.

[0098] During the movement of the charging plug assembly 30, the power transmission cable 61 will move accordingly. The first rolling element 631 rolls and supports the power transmission cable 61, so that the power transmission cable 61 is rolled and connected to the charging plug assembly 30, which helps to reduce the mutual interference between the charging plug assembly 30 and the power transmission cable 61.

[0099] Specifically, the first rolling element 631 transforms the sliding friction between the power transmission cable 61 and the charging plug assembly 30 into rolling friction, reducing the friction between the power transmission cable 61 and the charging plug assembly 30 during movement. This reduces the resistance experienced by the power transmission cable 61 and the charging plug assembly 30 during relative movement, making it easier for the charging plug assembly 30 to move closer to or further away from the power supply box 90, thus improving the charging efficiency of the charging device 2 for the power supply box 90. The reduced resistance to movement of the charging plug assembly 30 also facilitates precise control of its movement, such as displacement and angle, improving the accuracy of position adjustment. This allows the charging plug assembly 30 to precisely connect to one charging panel 91 of the power supply box 90 or alternately connect to multiple charging panels 91, improving the charging accuracy of the charging device 2 for multi-circuit power supply box 90. The sliding friction between the power transmission cable 61 and the charging plug assembly 30 is transformed into rolling friction, which helps to reduce the risk of wear or even damage to the power transmission cable 61, extend the service life of the power transmission cable 61, and has better economic benefits.

[0100] Therefore, by using the first rolling element 631 to support the power transmission cable 61, the sliding friction between the power transmission cable 61 and the charging plug assembly 30 can be shifted to rolling friction. This helps reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 when they move relative to each other. This can both increase the movement speed of the power transmission cable 61 and the charging plug assembly 30 and improve the movement accuracy of the charging plug assembly 30, thereby improving the charging efficiency and accuracy of the charging device 2 for the box-type power supply 90. It also helps reduce the wear of the power transmission cable 61 and extend its service life, thus improving the service life of the charging device 2. This method is economical.

[0101] In some embodiments, such as Figures 5-11 As shown, the second support assembly 63 also includes a second rolling element 632, which is spaced apart from the first rolling element 631. The power transmission cable 61 is movably located between the first rolling element 631 and the second rolling element 632, and the second rolling element 632 rolls in cooperation with the power transmission cable 61. For example, if the first rolling element 631 and the second rolling element 632 are arranged spaced apart along the vertical direction F3, then the second rolling element 632 is located on the upper side of the power transmission cable 61, and the first rolling element 631 and the second rolling element 632 can limit the power transmission cable 61 along the vertical direction F3.

[0102] During the movement of the charging plug-in assembly 30, the power transmission cable 61 moves accordingly. The first rolling element 631 and the second rolling element 632 can limit the movement of the power transmission cable 61, reducing the risk of it detaching from the second support component 63 and improving the stability of the connection between the power transmission cable 61 and the charging plug-in assembly 30. Furthermore, the rolling connection between the power transmission cable 61 and the second rolling element 632 reduces the friction between them, thus reducing the resistance experienced by the power transmission cable 61. This, in turn, reduces the resistance experienced by the power transmission cable 61 when it moves relative to the charging plug-in assembly 30, which helps improve the charging efficiency and accuracy of the charging device 2 for the box-type power supply 90.

[0103] Therefore, the first rolling element 631 and the second rolling element 632 can limit the power transmission cable 61, making it difficult for the power transmission cable 61 to separate from the charging plug assembly 30. The limiting effect is good. In addition, the second rolling element 632 is rolled to the power transmission cable 61, which helps to reduce the resistance encountered by the power transmission cable 61 when it moves relative to the charging plug assembly 30, thereby improving the charging efficiency and charging accuracy of the charging device 2 for the box-type power supply 90.

[0104] In some embodiments, such as Figures 5-11As shown, in at least one second support assembly 63, one of the first rolling element 631 and the second rolling element 632 is a roller 633. The outer circumferential surface of the roller 633 is provided with an annular groove 6331 extending circumferentially along the roller 633. The power transmission cable 61 is located within the annular groove 6331. The annular groove 6331 can limit the movement of the power transmission cable 61, making it less likely for the power transmission cable 61 to move significantly in the direction of the rolling axis of the roller 633. This allows the power transmission cable 61 to move as far as possible along its own extension direction at the second support assembly 63, which helps to reduce the relative movement between the power transmission cable 61 and the charging connector 351 at its output end, thereby improving the connection stability between the power transmission cable 61 and the charging connector 351. It also facilitates the connection of the power transmission cable 61 to the box-type power supply 90 via the charging connector 351 of the charging plug assembly 30 along its own extension direction, reducing the risk of misalignment between the charging connector 351 at the output end of the power transmission cable 61 and the charging panel 91 of the box-type power supply 90, thus preventing normal connection and improving the charging accuracy of the charging device 2 to the box-type power supply 90.

[0105] In some embodiments, such as Figures 5-11 As shown, there are multiple power transmission cables 61 and multiple rollers 633, each corresponding to one of the power transmission cables 61. The multiple power transmission cables 61 are located in the annular grooves 6331 of the multiple rollers 633, which makes it less likely for the multiple power transmission cables 61 to interfere with each other, which helps to improve the reliability, stability and safety of the multiple power transmission cables 61, and also facilitates subsequent maintenance and repair.

[0106] The second support assembly 63 also includes a support shaft 634 and a spacer 635, with multiple rollers 633 and spacers 635 all fitted onto the support shaft 634. Each roller 633 and spacer 635 can be fixedly connected to or rotatably connected to the support shaft 634, and the support shaft 634 can be fixedly connected to or rotatably connected to the charging plug-in assembly 30.

[0107] Adjacent rollers 633 are abutted and limited by spacers 635, making it difficult for multiple rollers 633 to move relative to each other, such as moving closer or further apart, and ensuring the stable position of the multiple rollers 633. The spacers 635 also space the multiple rollers 633 apart, increasing the spacing between the power transmission cables 61 on adjacent rollers 633, making it less likely for adjacent power transmission cables 61 to interfere with each other. Furthermore, during the assembly of the second support assembly 63, it is less likely for adjacent rollers 633 to interfere with each other, facilitating installation.

[0108] Therefore, by using multiple rollers 633 and spacers 635 between adjacent rollers 633, the multiple rollers 633 are less likely to interfere with each other, which helps to reduce the possibility of interference such as entanglement and friction between different power transmission cables 61, which helps to extend the service life of the power transmission cables 61 and improve the working reliability, stability and safety of the power transmission cables 61.

[0109] In some embodiments, such as Figures 5-11 As shown, in at least one second support assembly 63, the other of the first rolling element 631 and the second rolling element 632 is a rotating rod 636, and there are multiple rollers 633. The outer peripheral surface of the rotating rod 636 stops at the groove of the annular groove 6331 of the multiple rollers 633. The rotating rod 636 can limit the power transmission cable 61 within the annular groove 6331, reducing the risk of the power transmission cable 61 coming off the second support assembly 63. The rotating rod 636 and the rollers 633 cooperate to achieve the anti-detachment function for the power transmission cable 61, which helps to improve the stability of the connection between the power transmission cable 61 and the charging plug assembly 30.

[0110] In some embodiments of this utility model, such as Figures 1-11 As shown, the charging plug-in assembly 30 includes a first moving module 31, which is movably disposed on the charging base 10 along a first direction F1. The first moving module 31 can be directly or indirectly disposed on the charging base 10. The first moving module 31 can be movably disposed on the charging base 10 through the cooperation of the guide rail 301 and the slider 302, the cooperation of the piston and the cylinder, the lead screw and nut structure, or other structures. The first direction F1 can be the length direction of the external device, such as the box-type power supply 90, or at a certain angle to the length direction of the box-type power supply 90.

[0111] For example, in some embodiments, such as Figures 1-7 As shown, the first direction F1 is the length direction of the box-type power supply 90, and the first moving module 31 is indirectly mounted on the charging base 10 through the moving platform 40. The first moving module 31 is mounted on the moving platform 40 through the cooperation of the guide rail 301 and the slider 302, and the moving platform 40 is mounted on the charging base 10 through the cooperation of the guide rail 301 and the slider 302.

[0112] The first moving module 31 is used to drive the charging connector 351 to move relative to the charging base 10 along the first direction F1 to engage with the charging port. For example, the first moving module 31 drives the charging connector 351 to move closer to the charging port along the first direction F1 to engage with the charging port, or the first moving module 31 drives the charging connector 351 to move away from the charging port along the first direction F1 to disengage from the charging port.

[0113] The first moving module 31 is movable relative to the charging base 10 along the first direction F1. The first moving module 31 enables the charging connector 351 to have a degree of freedom of movement along the first direction F1, facilitating control of the charging connector 351's movement along the first direction F1 to adjust its position. Adjusting the position of the charging connector 351 in the first direction F1 allows for more precise alignment of the charging connector 351 with the charging port of the charging panel 91, improving the insertion accuracy of the charging connector 351 and the charging port in the charging panel 91.

[0114] The first rolling element 631 and the support wheel 622 can roll along the first direction F1 to allow the power transmission cable 61 to move along the first direction F1. By supporting the power transmission cable 61 with the rolling of the support wheel 622 and the first rolling element 631, during the process of the charging connector 351 moving relative to the charging base 10 along the first direction F1 to engage with the charging port, the sliding friction between the power transmission cable 61 and the running surface can be converted into rolling friction, and the sliding friction between the power transmission cable 61 and the charging connector assembly 30 can be converted into rolling friction. This helps to reduce the frictional resistance experienced by the charging connector 351 and the power transmission cable 61 during movement, improves the efficiency of the charging connector 351 engaging with the charging port, and thus improves the charging efficiency of the charging device 2 for the box-type power supply 90.

[0115] In some embodiments, such as Figures 1-11 As shown, the charging plug-in assembly 30 includes a second moving module 32, which is movably disposed on the first moving module 31 along a second direction F2. The second moving module 32 can be directly or indirectly disposed on the first moving module 31. The second moving module 32 can be movably disposed on the first moving module 31 through the cooperation of a guide rail 301 and a slider 302, the cooperation of a piston and a cylinder, a lead screw and nut structure, or other structures. The second direction F2 can be the width direction of an external device such as a box-type power supply 90, or at a certain angle to the width direction of the box-type power supply 90. For example, in some embodiments, such as... Figures 1-7 As shown, the second direction F2 is the width direction of the box-type power supply 90, and the second moving module 32 is directly mounted on the first moving module 31 through the cooperation of the guide rail 301 and the slider 302.

[0116] The second moving module 32 is used to drive the charging connector 351 to move relative to the first moving module 31 along the second direction F2, which intersects with the first direction F1. At least one second support component 63 is disposed on the second moving module 32. The second support component 63 disposed on the second moving module 32 can move along the second direction F2 with the second moving module 32, so that the second support component 63 and the power transmission cable 61 at the second moving module 32 can move along the second direction F2 and the first direction F1 with the second moving module 32. The power transmission cable 61 can move stably with the second moving module 32 without easily slipping or violently shaking, which helps to improve the stability of the charging connector 351 moving along the first direction F1 and the second direction F2.

[0117] The second moving module 32 is movable relative to the first moving module 31 along the second direction F2. This allows the charging connector 351 to have a degree of freedom of movement along the second direction F2, facilitating control of the charging connector 351's movement to adjust its position. Small adjustments to the position of the charging connector 351 in the first and second directions F1 can more precisely align it with the charging port of the charging panel 91, improving the insertion accuracy. Large adjustments can also be made to the position of the charging connector 351 in the first and second directions F2, allowing the same charging connector 351 to alternately connect to the charging ports of multiple charging panels 91 of the box-type power supply 90, enabling charging of multiple circuit box-type power supplies 90.

[0118] The first moving module 31, the second moving module 32, and the connector panel with charging connector 351 can each be one, two, or more. The position of the same connector panel can be adjusted so that the charging connector 351 of the same connector panel can alternately plug into the charging ports of multiple charging panels 91 of the multi-circuit box-type power supply 90. Alternatively, the number of the first moving module 31, the second moving module 32, and the connector panels can be adjusted to achieve charging of the multi-circuit box-type power supply 90. For example, in some embodiments, there are two second moving modules 32, spaced apart from the first moving module 31 along the second direction F2. Each second moving module 32 has a connector panel, allowing the charging connectors 351 of the two connector panels to plug into the charging ports of the two charging panels 91 respectively, thereby achieving charging of the dual-circuit box-type power supply 90.

[0119] By using the first moving module 31 and the second moving module 32, the control accuracy of the moving displacement of the charging connector 351 along the first direction F1 and the second direction F2 can be improved, thereby improving the control accuracy of the position of the charging connector 351. This allows the charging connector 351 to be accurately electrically connected to the corresponding charging panel 91, resulting in higher insertion and removal accuracy and a higher success rate when the same charging connector 351 is inserted into one charging panel 91 or alternately into multiple charging panels 91.

[0120] The support wheel 622 can roll along the second direction F2, allowing the power transmission cable 61 to move along the second direction F2. By supporting the power transmission cable 61 by the rolling of the support wheel 622, the sliding friction between the power transmission cable 61 and the traveling surface can be converted into rolling friction during the movement of the charging connector 351 relative to the first moving module 31 along the second direction F2. This helps to reduce the frictional resistance experienced by the charging connector 351 and the power transmission cable 61 during their movement, improves the efficiency of the plugging and unplugging of the charging connector 351 and the charging port, and thus improves the charging efficiency of the charging device 2 for the box-type power supply 90.

[0121] In some embodiments, such as Figures 1-11 As shown, the external device includes a plurality of charging panels 91, which are arranged sequentially along a second direction F2 at one end of the external device facing the charging plug assembly 30. The charging plug assembly 30 includes one unit that is movable relative to the external device along the second direction F2 to engage with any one of the plurality of charging panels 91.

[0122] For example, the second moving module 32 can drive the charging connector 351 to move between multiple positions arranged sequentially along the second direction F2, so that the charging connector 351 can be directly opposite one of the multiple charging panels 91 at any position. At this time, the first moving module 31 can drive the charging connector 351 to plug and cooperate with the charging port on the charging panel 91 to charge the circuit corresponding to the charging panel 91. After the circuit is charged, the second moving module 32 can drive the charging connector 351 to move in the second direction F2 to be directly opposite other charging panels 91 at other positions, and plug and cooperate with the charging port on the currently directly opposite charging panel 91. In this way, the charging of multiple circuits corresponding to multiple charging panels 91 can be realized.

[0123] Therefore, a single charging plug assembly 30 can meet the charging needs of external devices with multiple charging panels 91, reducing the cost of the charging device 2 and improving its applicability.

[0124] In some embodiments, such as Figures 1-11As shown, the charging plug-in assembly 30 includes a third moving module 33, which is movably disposed on the second moving module 32 along the vertical direction F3. A charging connector 351 is disposed on the third moving module 33, and can be directly or indirectly disposed on the third moving module 33. The third moving module 33 can be directly or indirectly disposed on the second moving module 32, and can be movably disposed on the second moving module 32 through the cooperation of guide rail 301 and slider 302, piston and cylinder cooperation, lead screw and nut structure, or other structures. The vertical direction F3 can be the height direction of an external device such as a box-type power supply 90, or at a certain angle to the height direction of the box-type power supply 90. For example, in some embodiments, such as... Figures 1-7 As shown, the vertical direction F3 is the height direction of the box-type power supply 90. The third moving module 33 is directly mounted on the second moving module 32 through the cooperation of the guide rail 301 and the slider 302.

[0125] The third moving module 33 drives the charging connector 351 to move relative to the second moving module 32 along the vertical direction F3, where the first direction F1, the second direction F2, and the vertical direction F3 intersect each other. At least one second support component 63 is disposed in the third moving module 33, and the second support component 63 disposed in the third moving module 33 can move with the third moving module 33 along the vertical direction F3. The third moving module 33 is movable relative to the second moving module 32 along the vertical direction F3, enabling the charging connector 351 to have a degree of freedom of movement along the vertical direction F3, thus facilitating the control of the charging connector 351's movement along the vertical direction F3 to adjust its position.

[0126] The first moving module 31, the second moving module 32, and the third moving module 33 enable the charging connector 351 to have degrees of freedom of movement along the first direction F1, the second direction F2, and the up-down direction F3. This allows control over the movement of the charging connector 351 along these directions to adjust its position. Small adjustments can be made to more precisely align the charging connector 351 with the charging port of the charging panel 91, improving the insertion accuracy. Large adjustments can also be made to allow the same charging connector 351 to be alternately inserted into multiple charging panels 91 of the box-type power supply 90, enabling charging of the multi-circuit box-type power supply 90.

[0127] The first moving module 31, the second moving module 32, the third moving module 33, and the charging connector 351 can each be one, two, or more. The position of the same charging connector 351 can be adjusted so that it can alternately connect to multiple charging panels 91 of the multi-circuit box-type power supply 90. Alternatively, the number of each of the first moving module 31, the second moving module 32, the third moving module 33, and the charging connector 351 can be adjusted to achieve charging of the multi-circuit box-type power supply 90. For example, in some embodiments, there are two second moving modules 32, spaced apart from the first moving module 31 along the second direction F2. Each second moving module 32 has a third moving module 33, and each third moving module 33 has a connector panel, allowing the charging connectors 351 of the two connector panels to connect to the charging ports of the two charging panels 91 respectively, thus charging the dual-circuit box-type power supply 90.

[0128] By using the first moving module 31, the second moving module 32, and the third moving module 33, the control accuracy of the moving displacement of the charging connector 351 along the first direction F1, the second direction F2, and the up and down direction F3 can be improved, thereby improving the control accuracy of the position of the charging connector 351. This allows the charging connector 351 to be accurately electrically connected to the corresponding charging panel 91, resulting in higher insertion and removal accuracy and a higher success rate when the same charging connector 351 is inserted into one charging panel 91 or alternately into multiple charging panels 91.

[0129] There are multiple second support components 63, with at least one second support component 63 disposed on the second moving module 32, enabling the second support component 63 and the power transmission cable 61 at the second moving module 32 to move along the second direction F2 and the first direction F1 with the second moving module 32. At least one second support component 63 is disposed on the third moving module 33, enabling the second support component 63 and the power transmission cable 61 at the third moving module 33 to move along the vertical direction F3, the second direction F2, and the first direction F1 with the third moving module 33.

[0130] In some related technologies, box-type power supplies typically employ dual-circuit charging. After one power supply is fully charged, the charging gun needs to be manually unplugged and plugged into the charging socket of the other power supply, which is time-consuming and laborious. In this application, the first moving module 31, the second moving module 32, and the third moving module 33 enable the charging connector 351 to move along the first direction F1, the second direction F2, and the up-down direction F3 with high precision. This improves the insertion accuracy of the charging connector 351 and the corresponding charging panel 91, and also facilitates the alternating insertion of the same charging connector 351 with different charging panels 91 of the box-type power supply 90, meeting the charging needs of different circuits in the box-type power supply 90 with high insertion and removal precision. Furthermore, both the second moving module 32 and the third moving module 33 are equipped with at least one second support component 63, ensuring that the power transmission cable 61 can move stably with the second moving module 32 and the third moving module 33 without slipping or violently shaking, thus improving the stability of the charging connector 351 moving along the first direction F1, the second direction F2, and the up-down direction F3.

[0131] In some embodiments, such as Figures 5-11 As shown, the second support assembly 63 also includes a second rolling element 632, and the power transmission cable 61 is movably located between the first rolling element 631 and the second rolling element 632. In the second support assembly 63 of the second moving module 32, one of the first rolling element 631 and the second rolling element 632 is a roller 633 and the other is a rotating rod 636. In the same second support assembly 63 of the second moving module 32, the roller 633 and the rotating rod 636 are arranged at intervals, and the power transmission cable 61 is movably located between the roller 633 and the rotating rod 636. This reduces resistance through the rolling friction between the roller 633 and the rotating rod 636 and the power transmission cable 61, and also through the annular groove 6331 of the roller 633 extending along the rolling axis of the roller 633 (e.g., ...). Figures 5-11 The power transmission cable 61 is limited in the second direction (F2) shown, and can also be limited by the roller 633 and the rotating rod 636 in the arrangement direction of the first rolling element 631 and the second rolling element 632 (e.g., Figures 5-11 The power transmission cable 61 is limited in the up-down direction (F3) shown, which has a better limiting effect on the power transmission cable 61 and makes the power transmission cable 61 more stable as it moves with the second moving module 32.

[0132] In the second support assembly 63 of the third moving module 33, both the first rolling element 631 and the second rolling element 632 are rotating rods 636. By arranging the two rotating rods 636 at intervals within the same second support assembly 63 of the third moving module 33, the power transmission cable 61 is movably located between the two rotating rods 636. This reduces resistance through the rolling friction between each of the two rotating rods 636 and the power transmission cable 61, and also improves the arrangement direction of the two rotating rods 636 in the first rolling element 631 and the second rolling element 632 (e.g., ...). Figures 5-11 The power transmission cable 61 is limited in the up-down direction (F3) shown, which improves the stability of the power transmission cable 61 as it moves with the third moving module 33. Furthermore, the second support component 63 at the second moving module 32 satisfies the limitation requirement of the power transmission cable 61 in the direction of the roller 633's rolling axis extension. Therefore, at the third moving module 33, two relatively simple moving rods can satisfy the limitation requirement of the power transmission cable 61 in the arrangement direction of the first rolling element 631 and the second rolling element 632, making it less likely for the power transmission cable 61 to detach. In embodiments where there are multiple power transmission cables 61, different power transmission cables 61 are less likely to interfere with each other, resulting in better stability of the power transmission cable 61 as it moves with the charging plug-in assembly 30.

[0133] Therefore, through the roller 633 and rotating rod 636 of the second support component 63 at the second moving module 32, it is possible to extend the roller 633 along its rolling axis (e.g., Figures 5-11 The power transmission cable 61 is limited in the second direction F2 shown, and in the arrangement direction of the first rolling element 631 and the second rolling element 632 (as shown in the figure). Figures 5-11 The power transmission cable 61 is limited in the up-down direction (F3) shown. Through the two rotating rods 636 of the second support assembly 63 at the third moving module 33, the arrangement direction of the first rolling element 631 and the second rolling element 632 (as shown) can be adjusted. Figures 5-11 The power transmission cable 61 is limited in the up-down direction (F3) as shown, and the limiting effect on different parts of the power transmission cable 61 is good.

[0134] In some embodiments, such as Figures 5-11 As shown, the second moving module 32 is provided with two second support components 63. In one second support component 63, the rotating rod 636 is located above the roller 633, and in the other second support component 63, the rolling rod is located below the roller 633. The rotating rod 636 and the roller 633 in the two second support components 63 of the second moving module 32 are in opposite positions, which provides a better limiting effect on the power transmission cable 61.

[0135] In some embodiments of this utility model, such as Figures 7-11As shown, the support wheel 622 is a swivel wheel. The swivel wheel can move smoothly in any direction, allowing the support wheel 622 to adapt to the movement of the power transmission cable 61 in any direction. Therefore, by designing the support wheel 622 as a swivel wheel, the movement flexibility of the support wheel 622 can be improved, enabling the power transmission cable 61 to move smoothly in any direction at the swivel wheel. Furthermore, the swivel wheel can freely turn within a limited space, quickly responding to the movement of the power transmission cable 61. This further reduces the resistance experienced by the power transmission cable 61 and the charging plug assembly 30 during movement, thereby improving the charging efficiency and accuracy of the charging device 2 for the box-type power supply 90.

[0136] like Figures 1-4 As shown, the charging system 1 according to an embodiment of the present invention includes a seating frame 20 and a charging device 2 according to an embodiment of the present invention. The seating frame 20 is connected to the charging device 2 and is used to place external devices such as box-type power supplies 90.

[0137] In some related technologies, tower cranes are typically used to hoist the box-type power supply to the charging device. However, this requires repeated adjustments of the box-type power supply's position by the tower crane to align it with the charging device before lowering it. This results in excessive hoisting time and long on-site alignment time (aligning the box-type power supply and the charging device), leading to low charging efficiency. This application, however, uses a mounting frame 20 to place the box-type power supply 90, enabling rapid hoisting of the box-type power supply 90 onto the mounting frame 20 without the need for repeated adjustments. This shortens on-site alignment time, facilitates installation, and allows for rapid placement of the box-type power supply 90 at the battery swapping station. It also ensures high charging efficiency and eliminates the need for additional facilities at the battery swapping station to house the box-type power supply 90, reducing the construction cycle and allowing for rapid operation.

[0138] Because the charging device 2 according to the present invention has the above-mentioned beneficial technical effects, the charging system 1 according to the present invention stabilizes the power transmission cable 61 through the support member 621 in the first support component 62, and transforms the sliding friction between the power transmission cable 61 and the traveling surface into rolling friction through the support wheel 622 in the first support component 62. This helps to reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during movement, which can both accelerate the movement speed of the power transmission cable 61 and the charging plug assembly 30 and improve the movement accuracy of the charging plug assembly 30. This improves the charging efficiency and charging accuracy of the charging device 2 for external devices such as the box-type power supply 90, and also helps to reduce the wear of the power transmission cable 61 to extend its service life, thereby improving the service life of the charging device 2 and making it more economical. By placing the box-type power supply 90 on the seating frame 20, the time for adjusting the position of the box-type power supply 90 is shortened, and the box-type power supply 90 can be quickly placed for charging by the charging device 2, thus improving the charging efficiency of the box-type power supply 90.

[0139] In some embodiments, such as Figures 1-4 As shown, the seating frame 20 is provided with a guide component 21. The guide component 21 has a guide slope extending from top to bottom and inward, so as to guide the box-type power supply 90 through the guide slope during the process of placing the box-type power supply 90 on the seating frame 20, so that the box-type power supply 90 is opposite to the charging device 2 along the first direction F1 after being placed on the seating frame 20, which helps to reduce the difficulty of placing the box-type power supply 90 and improve the placement accuracy of the box-type power supply 90.

[0140] In some embodiments, such as Figures 1-2 As shown, the charging system 1 is used to charge the box-type power supply 90, which is a replaceable power source for electric vessels. This enables electric vessels to swap batteries, reducing charging and swapping waiting time. Furthermore, the box-type power supply 90 can be charged on shore using the charging system 1, without being restricted by the location of the electric vessel, making charging time more flexible and improving the docking accuracy between the charging system 1 and the box-type power supply 90.

[0141] The following describes in detail a charging system 1 according to a specific embodiment of the present invention with reference to the accompanying drawings. It is to be understood that the following description is merely illustrative and should not be construed as limiting the present invention.

[0142] like Figures 1-11 As shown, a charging system 1 according to a specific embodiment of the present invention includes a seating frame 20 and a charging device 2. The seating frame 20 is connected to the charging device 2. The seating frame 20 is used to place external equipment, which is a box-type power supply 90. The charging device 2 is used to charge the box-type power supply 90, which is a replaceable power supply for electric ships.

[0143] The charging device 2 includes a charging base 10, a charging plug-in assembly 30, a moving platform 40, a protective cover 50, a power transmission cable 61, a first support assembly 62, and a second support assembly 63. The charging base 10 includes a charging frame 12 and two moving guide rails 11. The moving guide rails 11 extend along a first direction F1, and the two moving guide rails 11 are spaced apart along a second direction F2 and positioned on the charging frame 12. The first direction F1, the second direction F2, and the vertical direction F3 are perpendicular to each other.

[0144] The box-type power supply 90 has two charging panels 91, each with three charging ports. The two charging panels 91 are arranged sequentially along the second direction F2 at one end of the box-type power supply 90 facing the charging plug assembly 30. The charging plug assembly 30 is a single assembly, which is movable relative to the box-type power supply 90 along the second direction F2 to engage with either of the two charging panels 91.

[0145] The moving platform 40 is movably mounted on the moving guide rail 11 of the charging base 10 along the first direction F1 via supporting rollers 41. The protective cover 50 covers the moving platform 40 and is fixedly connected to the moving platform 40. The protective cover 50 has two square mating interfaces on the side wall facing the seating frame 20 in the first direction F1, and the two mating interfaces are spaced apart along the second direction F2. A detector is provided between the two mating interfaces. A protective curtain is provided inside the cover. The protective curtain is a roller shutter door and is movable in the vertical direction F3 to open and close the mating interfaces. The cover has an outward flange at each mating interface, and a blocking member extends circumferentially along the mating interface and is arranged around the outward flange. The blocking member has an N-shaped structure with the opening facing downward. The first flange of the blocking member is fixedly connected to the cover by a pressure strip and fasteners, and the second flange of the blocking member is used to contact and cooperate with the charging panel 91 of the box-type power supply 90. The shielding component has a water-guiding channel, which consists of a first channel section and two second channel sections. This channel is used to guide rainwater and other water flow downwards, reducing the risk of water ingress between the enclosure and the shielding component, and between the box-type power supply 90 and the shielding component. The enclosure has inspection doors on its two opposite side walls in the second direction F2. An electrical control box is located inside the enclosure, and an alarm is located on the top of the enclosure.

[0146] The charging plug-in assembly 30 is located within the receiving space of the protective cover 50 and is movably mounted on the mobile platform 40. The charging plug-in assembly 30 includes a charging connector 351 for plugging into the charging port of the box-type power supply 90 along the first direction F1, and the tail end of the charging connector 351 is connected to the power transmission cable 61.

[0147] Three power transmission cables 61 are arranged along the second direction F2, and four first support components 62 are spaced apart along the extension direction of the power transmission cables 61, i.e., the first direction F1. Each first support component 62 includes a support member 621 and two support wheels 622. The support member 621 includes a base plate 6211 and three support parts 6212 spaced apart along the second direction F2. The support wheels 622 are casters, located on the lower side of the base plate 6211, and the multiple support parts 6212 are located on the upper side of the base plate 6211. The three power transmission cables 61 are connected one-to-one to the three support parts 6212, and the three support parts 6212 are integrally connected to the two support wheels 622.

[0148] The support portion 6212 includes a first fastening portion 6213 and a second fastening portion 6214. The first fastening portion 6213 is disposed on the base plate 6211, and the second fastening portion 6214 fastens with the first fastening portion 6213 and defines a through hole for passing through the power transmission cable 61.

[0149] The power transmission cable 61 is mounted on the support member 621, and the support wheel 622 is located on the support member 621 and is used to support the cable on the walking surface. The power transmission cable 61 is supported by the support wheel 622 of the first support member 62 for rolling on the walking surface, and is also supported by the rollers 633 and the rotating rod 636 of the second support member 63 on the charging plug-in assembly 30 for rolling movement, so as to adapt to the movement of the power transmission cable 61 during the plugging and unplugging process and the posture adjustment process.

[0150] The power transmission cable 61 includes a first segment 611, a second segment 612 and a third segment 613. The first segment 611 is located on the lower side of the charging base 10 and is supported on the walking surface by the first support component 62. The second segment 612 is located on the upper side of the charging base 10 and is installed on the charging plug assembly 30. The third segment 613 is bent and extended to connect the first segment 611 and the second segment 612.

[0151] The charging and plugging assembly 30 includes a first moving module 31, a second moving module 32, a third moving module 33, a tilting module 34, and a plugging module 35. The connector panel of the plugging module 35 is provided with three charging connectors 351. The tail ends of the three charging connectors 351 are connected to three power transmission cables 61 in a one-to-one correspondence. The connector panel can be alternately plugged and plugged into two charging panels 91. Specifically, the head ends of the three charging connectors 351 on the connector panel are plugged and plugged into the three charging ports of the corresponding charging panels 91 in a one-to-one correspondence.

[0152] The first moving module 31 is movably mounted on the moving platform 40 along the first direction F1 via the guide rail 301 and the slider 302. The second moving module 32 is movably mounted on the first moving module 31 along the second direction F2 via the guide rail 301 and the slider 302. The third moving module 33 is movably mounted on the second moving module 32 along the up-down direction F3 via the guide rail 301 and the slider 302. The tilting module 34 is located between the third moving module 33 and the plug-in module 35, and the tilting module 34 can adjust the angle of the plug-in module 35.

[0153] The second support assembly 63 is mounted on the charging plug assembly 30, and the second support assembly 63 includes a first rolling element 631, which can roll along a first direction F1. The first rolling element 631 rolls and supports the power transmission cable 61, which extends sequentially along the arrangement direction of the first support assembly 62, the second support assembly 63, and the charging connector 351. The second support assembly 63 also includes a second rolling element 632, which is spaced apart from the first rolling element 631. The power transmission cable 61 is movably located between the first rolling element 631 and the second rolling element 632, and the second rolling element 632 rolls in cooperation with the power transmission cable 61.

[0154] There are three second support components 63: two second support components 63 are located in the second moving module 32, and one second support component 63 is located in the third moving module 33.

[0155] In the two second support components 63 of the second moving module 32, for the second support component 63 further away from the third moving module 33 along the first direction F1, the first rolling element 631 is a roller 633. The outer circumferential surface of the roller 633 is provided with an annular groove 6331 extending circumferentially along the roller 633, and the power transmission cable 61 is located in the annular groove 6331. There are three rollers 633, each corresponding to one of the three power transmission cables 61. The second support component 63 also includes a support shaft 634 and a spacer 635. The three rollers 633 and the spacer 635 are all sleeved on the support shaft 634, and adjacent two rollers 633 are abutted and limited by the spacer 635. The second rolling element 632 is a rotating rod 636. There are three rollers 633, and the outer circumferential surface of the rotating rod 636 stops at the groove opening of the annular groove 6331 of the three rollers 633.

[0156] In the two second support components 63 of the second moving module 32, for the second support component 63 closer to the third moving module 33 along the first direction F1, the second rolling element 632 is a roller 633. The outer circumferential surface of the roller 633 is provided with an annular groove 6331 extending circumferentially along the roller 633, and the power transmission cable 61 is located in the annular groove 6331. There are three rollers 633, which correspond one-to-one with the three power transmission cables 61. The second support component 63 also includes a support shaft 634 and a spacer 635. The three rollers 633 and the spacer 635 are all sleeved on the support shaft 634, and the adjacent two rollers 633 are abutted and limited by the spacer 635. The first rolling element 631 is a rotating rod 636, and there are three rollers 633. The outer circumferential surface of the rotating rod 636 stops at the groove opening of the annular groove 6331 of the three rollers 633.

[0157] In the second support component 63 of the third moving module 33, both the first rolling element 631 and the second rolling element 632 are rotating rods 636.

[0158] When the box-type power supply 90 needs to be charged, it can be placed on the base frame 20 by a hoisting device and guided by the guide assembly 21, so that the charging panel 91 of the box-type power supply 90 is as directly aligned as possible with the interface of the protective cover 50; the moving platform 40 moves along the charging base 10 in the first direction F1 towards the box-type power supply 90, and drives the protective cover 50 and the charging plug-in assembly 30 towards the box-type power supply 90 until the detector comes into contact with the box-type power supply 90, at which point the shielding part of the protective cover 50 contacts the box-type power supply 90. When the mobile platform 40 stops moving, the protective curtain opens the interface. Then, the identification component identifies the relative position and angle between the plug-in module 35 and the charging panel 91 through point laser ranging and 2D visual feature hole positioning. The charging plug-in assembly 30 adjusts the relative position through the first moving module 31, the second moving module 32, and the third moving module 33, and adjusts the relative angle through the yaw module 34, so that the plug-in module 35 is accurately aligned with the corresponding charging panel 91 through one of the interfaces and plugged in for charging. After the corresponding circuit of the charging panel 91 is fully charged, the first moving module 31 moves away from the box power supply 90 along the first direction F1 to separate the plug-in module 35 from the charging panel 91. The second moving module 32 moves along the second direction F2 to align the plug-in module 35 with the charging panel 91 corresponding to the other interface. By readjusting the relative position and angle, the first moving module 31 moves closer to the box power supply 90 along the first direction F1 to plug the plug-in module 35 into the charging panel 91 for charging.

[0159] After charging is complete, the plug-in module 35 is separated from the charging panel 91 by moving the first moving module 31 away from the box-type power supply 90 in the first direction F1. The protective cover 50 is separated from the box-type power supply 90 by moving the moving platform 40 away from the box-type power supply 90 in the first direction F1, and the protective curtain closes the interface. At this time, the box-type power supply 90 can be moved by hoisting.

[0160] In the above embodiments, the charging plug-in module 30 can actively adjust its charging posture with multiple degrees of freedom, enabling dual-circuit automatic plug-in charging. The charging connector 351 is highly aligned with the charging port of the charging panel 91, resulting in a high success rate for plugging and unplugging. The guide post of the plug-in module 35 and the pin of the charging port experience less wear, leading to a longer equipment lifespan and more stable and reliable performance. The modular design allows the charging station of the mounting frame 20 to be considered as one module, and the charging device 2 as another. These two modules can be quickly connected on-site using fasteners, eliminating the need for on-site alignment, facilitating installation, rapid deployment, reducing the construction cycle, and enabling quick operation. The protective cover 50's shielding component first engages with the box-type power supply 90, and then the protective curtain opens the interface before the plug-in module 35 extends to connect with the charging port of the charging panel 91. This provides excellent protection, eliminating the risk of leakage and short circuits, physically isolating the device from rain and snow, and ensuring safe and reliable outdoor use. The identification component uses laser ranging to measure the distance and angle of the charging panel 91 area of ​​the box-type power supply 90. The charging device 2 aligns the plug-in module 35 with the charging panel 91 and then uses 2D image acquisition to locate the feature hole position, achieving high positioning accuracy. The secondary tapered guide post on the plug-in module 35 aligns with the guide hole on the charging panel 91. The secondary tapered tolerance range is large, and the guide controls the alignment accuracy of the charging port and charging connector 351 within 0.3mm on one side, resulting in high plug-in accuracy and a high plug-in success rate.

[0161] The first support component 62 separates the power transmission cable 61 from the running surface, transforming the sliding friction between the power transmission cable 61 and the running surface into rolling friction. This reduces the frictional resistance between the power transmission cable 61 and the running surface, thereby reducing the resistance experienced by the power transmission cable 61 and the charging plug assembly 30 during movement. This facilitates the movement of the charging plug assembly 30, improving the insertion accuracy of the charging connector 351 and the corresponding charging panel 91, and also facilitates the alternating electrical connection of the charging connector 351 with the two charging panels 91 of the box-type power supply 90. The second support component 63 mounts the power transmission cable 61 onto the charging plug assembly, and both the roller 633 and the rotating rod 636 of the second support component 63 are in rolling contact with the power transmission cable 61, further reducing the frictional resistance experienced by the power transmission cable 61. With the cooperation of the second support component 63 on the second moving module 32 and the third moving module 33, the power transmission cable 61 can be limited along the second direction F2 and the up and down direction F3, so that the power transmission cable 61 is not easy to come out of the charging plug assembly 30, and different power transmission cables 61 are not easy to get tangled, rub or interfere with each other, which helps to improve the working reliability, stability and safety of the power transmission cable 61 and extend the service life of the power transmission cable 61.

[0162] Therefore, the first support component 62 and the second support component 63 can reduce the resistance encountered by the power transmission cable 61 and the charging plug assembly 30 during movement, which helps to accelerate the movement speed of the power transmission cable 61 and the charging plug assembly 30 and improve the movement accuracy of the charging plug assembly 30, thereby improving the charging efficiency and charging accuracy of the charging device 2 for the box-type power supply 90. The first support component 62 and the second support component 63 can also reduce the wear of the power transmission cable 61, thereby extending the service life of the power transmission cable 61 and improving the service life of the charging device 2, resulting in better economic efficiency.
