Description

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 depleted electric power supply from the vessel onto a transport vehicle on the shore and transports it to a battery swapping station. A front-end crane then lifts the depleted power supply from the transport vehicle and places it in the charging position for charging. However, the charging equipment in this technology does not meet rainproof requirements and cannot be used at shore charging stations or battery swapping stations. Utility Model Content

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one objective of the present invention is to provide a charging device that can provide rain and sun protection for the charging plug assembly, thereby meeting the needs of shore-based charging.

[0004] The charging device according to an embodiment of the present invention is used to charge an external device. The charging device includes: a charging plug assembly, the charging plug assembly including a charging connector for plugging into a charging port on the external device; and a protective cover including a cover wall defining an accommodating space, within which the charging plug assembly is at least partially accommodated; wherein the cover wall has a mating interface, from which the charging connector can extend for plugging into the charging port.

[0005] According to the embodiments of the present invention, the charging device can protect the charging plug assembly by means of a protective cover, thereby achieving protection functions such as rain and sun protection, which is beneficial to improving the service life of the charging plug assembly and improving the reliability of the charging connection between the charging plug assembly and external devices.

[0006] 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 protective cover further includes: a shielding member, the shielding member being disposed on the cover wall and extending along the edge of the mating interface, the shielding member being used to contact and cooperate with the outer wall of the external device.

[0007] In the above technical solution, the shielding component can block the gap between the cover wall and the outer wall of the external equipment, which makes it easier for the electrical connection between the charging connector and the charging port to be less likely to be wetted by rain or exposed to ultraviolet rays, thus greatly reducing the risk of water ingress and aging.

[0008] According to some embodiments of the present invention, the shielding member protrudes from the outer wall surface of the cover.

[0009] In the above technical solution, the protruding part of the shield can contact the outer wall of the external equipment, so that the external equipment does not need to extend into the inside of the shield wall, which helps to reduce the risk of interference and impact, and prevents the external equipment from bringing rainwater into the containment space.

[0010] According to some embodiments of the present invention, the shielding member includes a first flange, a second flange, and a connecting portion. The first flange extends along the edge of the interface and is connected to the cover wall. The second flange is spaced apart from the first flange in the through direction of the interface and is used to contact and cooperate with the external device. The connecting portion connects the first flange and the second flange so that the first flange, the second flange, and the connecting portion cooperate to define a water guide groove. The water guide groove is located on the side of the connecting portion opposite to the center of the interface.

[0011] In the above technical solution, the water guide channel can guide the water flow between the cover wall and the external equipment during rainy or snowy weather, thereby reducing the risk of water flowing between the external equipment and the shield, or between the cover wall and the shield, and further reducing the risk of water ingress.

[0012] According to some embodiments of the present invention, the protective cover further includes a pressure strip, the first flange is sandwiched between the pressure strip and the cover wall, and fasteners are passed through the pressure strip, the first flange and the cover wall to connect the pressure strip, the first flange and the cover wall.

[0013] In the above technical solution, fasteners can be used to lock the first flange and the cover wall, thereby increasing the force between the first flange and the cover wall and improving the waterproof effect. The pressure strips can reduce the wear of the fasteners on the first flange, increase the service life of the first flange, and reduce the risk of water entering between the shield and the cover wall.

[0014] According to some embodiments of the present invention, the edge of the mating interface is provided with an outward flange perpendicular to the through direction of the mating interface. The outward flange is located on the side of the shielding member close to the center of the mating interface. The outward flange bends and extends in a direction away from the cover wall and then towards the shielding member.

[0015] In the above technical solution, by setting an outer flange, a bending path is formed from the gap between the first flange and the cover wall to the charging port. Even if a gap is formed between the first flange and the cover wall, causing water to flow from the gap between the first flange and the cover wall to the charging port, it needs to cross the outer flange to flow to the charging port, which further reduces the risk of water entering the charging port.

[0016] According to some embodiments of the present invention, the protective cover further includes a protective curtain, which is disposed at the interface and is used to cover and open the interface.

[0017] In the above technical solution, by setting up a protective curtain, when the protective cover is not in contact with external equipment, the curtain can block the charging port, preventing rainwater and other fluids from directly entering the containment space through the charging port, and also preventing sunlight from directly shining into the containment space through the charging port, thus improving the protective effect of the protective cover when not charging. When charging is required, the protective cover cooperates with external equipment, and the protective curtain can open the charging port to facilitate the connection and charging of the charging plug-in assembly with the external equipment.

[0018] According to some embodiments of the present invention, the cover wall is provided with a plurality of the said interfaces, and the protective curtains at at least two of the said interfaces are integral pieces.

[0019] In the above technical solution, the integrated protective curtain can be opened and closed by the same drive structure, realizing the simultaneous opening and closing of multiple charging ports, improving operating efficiency and reducing the number of drive structures, thereby reducing costs and weight.

[0020] According to some embodiments of the present invention, the protective cover further includes a positioning structure, which is disposed on the cover wall and used to detect the engagement state between the protective cover and the external device. The protective curtain is configured to open the interface when the protective cover and the external device are in place.

[0021] In the above technical solution, the positioning structure detects whether the protective cover and the external equipment are properly matched, and the charging port is opened when the protective cover and the external equipment are properly matched. This can prevent water from entering the charging port when the protective cover and the external equipment are not properly matched, thus further improving the protection effect.

[0022] According to some embodiments of the present invention, the positioning structure includes a probe, and the protective curtain is configured to open the interface when the probe is in contact with the external device.

[0023] In the above technical solution, the contact detection between the probe and the external device is used to check whether the contact and fit are in place, which has higher detection accuracy and is not affected by factors such as weather.

[0024] According to some embodiments of the present invention, the cover wall is provided with a plurality of the said interfaces, the positioning structure is located between two adjacent said interfaces, and the protective curtain is provided with a clearance notch for avoiding the positioning structure.

[0025] In the above technical solution, the avoidance gap can prevent the positioning structure from interfering with the movement of the protective curtain, and the area of ​​the protective curtain can be larger to improve the shielding effect on the charging port.

[0026] According to some embodiments of the present invention, the cover wall includes a support frame, a top plate and a plurality of side plates. The top plate is disposed on the upper side of the support frame and connected to the support frame, and the plurality of side plates are disposed on a plurality of sides of the support frame and connected to the support frame.

[0027] In the above technical solution, the overall structure of the cover wall has high strength, and it is connected to the support frame from the top and sides by the top plate and multiple side plates respectively, so that the bottom of the cover wall can be opened, that is, the accommodating space has a bottom opening, so that the cover wall can be placed on the charging plug assembly through the bottom opening, avoiding interference and making assembly easier.

[0028] According to some embodiments of the present invention, the charging device further includes a charging base and a mobile platform. The mobile platform is movably mounted on the charging base, the charging plug assembly is mounted on the mobile platform, and the protective cover is mounted on the mobile platform. The mobile platform is movable along a first direction to move the protective cover and the charging plug assembly closer to and away from the external device.

[0029] In the above technical solution, by setting up a charging base and a moving platform, the protective cover can be initially matched with the external device before the charging plug assembly is plugged in for charging to achieve protection, which is more effective in reducing water ingress into the charging plug structure, and the protective cover is easy to match with the external device.

[0030] According to some embodiments of the present invention, the cover wall is provided with two interfaces, the two interfaces are arranged along a second direction, the second direction intersects with the first direction, and the charging connector has a first position and a second position switchable along the second direction on the mobile platform, the first position corresponds to one of the two interfaces, and the second position corresponds to the other of the two interfaces.

[0031] In the above technical solution, by switching the charging connector between a first position and a second position, the charging connector can selectively extend from two mating interfaces, thereby interlocking with different charging ports of external devices to charge different circuits of the external devices. Thus, the charging device can meet the multi-circuit charging needs of external devices.

[0032] According to some embodiments of the present invention, the mobile platform is provided with a second direction translation guide rail, and the charging plug-in assembly moves on the second direction translation guide rail to switch the charging connector between the first position and the second position.

[0033] In the above technical solution, the charging plug-in assembly cooperates with the second direction translation guide rail and moves along the second direction translation guide rail, which can realize movement in the second direction, and the position switching control of the charging connector is more flexible.

[0034] According to some embodiments of the present invention, the charging plug-in assembly includes a first moving module and a second moving module. The first moving module is disposed on the moving platform, and the charging connector is disposed on the second moving module. The second moving module is movably mounted on the first moving module along the second direction so that the charging connector can switch between the first position and the second position.

[0035] In the above technical solution, the position switching of the charging connector has no effect on the movement of the charging plug assembly relative to the moving platform, making the position and installation structure design of the charging plug assembly relative to the moving platform more flexible, which is conducive to more reliable installation and more flexible position adjustment.

[0036] According to some embodiments of the present invention, the mobile platform includes a first-direction translational guide rail, and the charging plug-in assembly moves on the first-direction translational guide rail to realize the plugging and unplugging of the charging connector and the charging port.

[0037] In the above technical solution, the charging plug-in assembly cooperates with the first-direction translational guide rail and moves along the first-direction translational guide rail, thus realizing movement in the first direction. After adjusting the position of the charging connector in the second direction, the charging connector is plugged in and unplugged from the charging port through translation in the first direction, resulting in better centering.

[0038] Another objective of this invention is to provide a charging system having the aforementioned charging device.

[0051] In the embodiments of this utility model, 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 utility model shown in the 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 utility model.

[0052] In this utility model, "multiple" refers to two or more (including two).

[0053] 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.

[0054] The box-type power supply mentioned in this application refers to an integrated and modular power equipment, which typically integrates power modules, control systems, heat dissipation devices, protection units, fire protection facilities, etc. into a protective box. It has the characteristics of flexible deployment, strong environmental adaptability, and safety and reliability. For example, box-type power supplies may include containerized battery power supplies, boxed UPS power supplies, trolley box-type energy storage mobile power supplies, and box-type intelligent power supplies.

[0055] 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.

[0056] 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.

[0057] The charging system is used to charge the energy storage system. Taking the charging scenario of electric ships as an example, the shore-based charging system charges the energy storage system (such as a box-type power supply) of the electric ship. The charging system can be a fixed device, and the box-type power supply can be a mobile device. The box-type power supply is detachable. After the ship docks, the box-type power supply can be disassembled by hoisting and then transported to the battery swapping station for charging by the charging system.

[0058] The charging systems in the relevant technologies do not have the protection capabilities of rain and sun protection, and require the construction of indoor work sites to place the charging system and the box-type power supply to be charged in the work site. This results in a large space occupation, difficulty in hoisting and operating the box-type power supply, or the need for outdoor charging, which limits the charging time. Especially in coastal areas with more rain and stronger ultraviolet radiation, the charging of box-type power supplies on ships has many limitations and is prone to aging.

[0059] Based on this, this application proposes a charging device, including a protective cover and a charging plug-in assembly. The charging plug-in assembly includes a charging connector for plugging into a charging port on an external device. The protective cover includes a cover wall defining a receiving space, within which the charging plug-in assembly is at least partially received. The cover wall has a mating interface from which the charging connector can extend for plugging into the charging port.

[0060] In the embodiments of this application, the protective cover can shield and protect the charging plug assembly, achieving protection functions such as rainproof, snowproof, hailproof, dustproof, and sunproof, which helps to improve the service life of the charging plug assembly and improve the reliability of the charging connection between the charging plug assembly and external devices.

[0061] The charging device in this embodiment is used for charging equipment, 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 equipment such as ships and spacecraft. Spacecraft can include aircraft, rockets, space shuttles, and spacecraft.

[0062] For ease of explanation, the following embodiments use an external device as a box-type power supply for electric ships. For the purpose of explanation, the charging device of the charging system can be used to charge the box-type power supply of the electric ship.

[0063] Reference Figures 1-4 , Figure 1 and Figure 2 This is a schematic diagram showing the matching structure of the charging system 1 and the box-type power supply 90 at different angles in some embodiments of this utility model. Figure 3 This is a schematic diagram of the charging system 1 according to an embodiment of the present utility model; Figure 4 This is a partial cross-sectional view of the charging system 1 according to an embodiment of the present utility model. The electric ship has a box-type power supply 90, which is used to supply power to the electric ship. For example, the box-type power supply 90 can serve as the driving power supply, operating power supply, and living power supply for the electric ship, such as for the power needs of the electric ship during startup, navigation, and navigation, as well as for living needs.

[0064] In the embodiments of this application, such as Figures 1-2 As shown, the box-type power supply 90 is an integrated independent power system that highly integrates a power generation unit, an energy storage unit, an energy management system, a temperature control system, a fire protection system, and a power distribution unit into a standardized, modular, and movable protective enclosure. The box-type power supply 90 typically has one or more charging panels 91, each equipped with a charging port. Each charging panel 91 is electrically connected to an electrical circuit within the box-type power supply 90. The charging system 1 can be electrically connected to charging stations, battery swapping stations, smart charging piles, or other energy storage devices, enabling the charging system 1 and the charging ports of the charging panels 91 to connect to the electrical circuits within the box-type power supply 90 for charging. The charging system 1, electrically connected to one or more charging panels 91, can charge one or more electrical circuits within the box-type power supply 90.

[0065] The charging device 2 and charging system 1 according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0066] Reference Figures 4-7 and Figures 9-10 As shown, Figure 5 This is a partial structural schematic diagram of a charging device according to an embodiment of the present utility model; Figure 6 and Figure 7 These are structural schematic diagrams of the protective cover 50 at different angles according to some embodiments of the present utility model; Figure 9 and Figure 10 This is a structural schematic diagram of the protective cover 50 according to other embodiments of the present invention. The charging device 2 according to embodiments of the present invention is used to charge external devices, and the charging device 2 may include a charging plug assembly 30 and a protective cover 50.

[0067] Specifically, the charging plug-in assembly 30 includes a charging connector 351 for mating with a charging port on an external device. The protective cover includes a cover wall 51 defining a receiving space 511 within which the charging plug-in assembly 30 is at least partially housed. The cover wall 51 has a mating interface 512 from which the charging connector 351 extends for mating with a charging port on an external device.

[0068] Charging plugging and unplugging refers to the process of inserting or unplugging the charging port of an external device during charging, such as inserting or unplugging the charging connector 351 into or out of the charging port of an external device to establish or disconnect the charging connection. This process involves mechanical connection, electrical connection and disconnection, communication interaction and safety protection mechanisms, and is one of the operations of device charging. Charging plugging and unplugging assembly 30 refers to the component that enables charging of external devices through charging plugging and unplugging.

[0069] The charging plug-in assembly 30 refers to a component that enables charging of external devices through charging plug-in. The charging connector 351 is a component that directly connects mechanically to the charging port of an external device and transmits electricity.

[0070] In some embodiments, the charging plug-in assembly 30 can achieve automatic plugging and unplugging, that is, the technology of using automated equipment to replace manual operation in connecting and disconnecting the charging connector 351 from the charging port. This technology can be applied to charging stations, battery swapping stations, smart charging piles, and other scenarios, which can improve charging efficiency, reduce manual intervention, and achieve unmanned operation.

[0071] For example, the charging plug assembly 30 may include an identification component that can identify the position of the charging connector 351 relative to the charging port of an external device, and further identify the relative angle, so that the charging plug assembly 30 can adjust the attitude of the charging connector 351 according to the identification result of the identification component.

[0072] The cover 51 refers to a main structure or component with covering, protection, and shielding functions. Its specific shape and material can be flexibly set according to actual conditions. Optionally, the cover 51 may include a top wall and a peripheral wall, with the upper ends of the top wall and the peripheral wall connected to define an accommodating space 511. The bottom of the accommodating space 511 has an opening so that the cover 51 can cover the charging plug assembly 30. The peripheral wall may be cylindrical or a prismatic shape composed of multiple flat side walls. Optionally, the cover 51 may also include a bottom wall, with the lower ends of the bottom wall connected to the peripheral wall to define the accommodating space 511. The charging plug assembly 30 may be supported by the bottom wall or installed on the top wall or the peripheral wall. The material of the cover 51 may be, but is not limited to, high-strength low-carbon steel, aluminum alloy, stainless steel, composite materials (such as aluminum and insulation layer), etc.

[0073] Interface 512 refers to an opening provided on the cover wall 51. Interface 512 can penetrate through the cover wall 51 along the wall thickness direction, so that components inside the receiving space 511 and components outside the receiving space 511 can be inserted or removed through interface 512. Interface 512 can be provided at least at one location on the top wall and peripheral wall of the cover wall 51, for example... Figure 6 and Figure 7 As shown, the enclosure 51 includes multiple sidewalls, one of which faces an external device and has an interface 512.

[0074] The cover wall 51 may have one or more connection interfaces 512, wherein the multiple connection interfaces 512 may be located on the same wall surface of the cover wall 51 or on different wall surfaces. Furthermore, in embodiments with multiple connection interfaces 512, the charging plug-in assembly 30 may charge external devices sequentially through the connection interfaces 512 or charge external devices simultaneously through multiple connection interfaces 512.

[0075] When charging an external device is required, the protective cover 50 can be aligned with the external device so that the interface 512 is directly opposite the charging port. Then, the charging connector 351 extends from the interface 512 and is plugged into the charging port for charging. During charging, the protective cover 50 can shield the electrical connection between the charging plug assembly 30, the charging connector 351, and the charging port, making it less susceptible to rain or ultraviolet radiation, greatly reducing the risk of water ingress and aging, and improving the service life of the charging plug assembly 30. According to the charging device 2 of this utility model embodiment, the protective cover 50 can shield and protect the charging plug assembly 30, achieving protection against rain, snow, hail, dust, and sun, which helps to improve the service life of the charging plug assembly 30 and the reliability of the charging connection between the charging plug assembly 30 and the external device.

[0076] According to some embodiments of this utility model, such as Figures 6-13 As shown, the protective cover 50 also includes a shield 52, which is disposed on the cover wall 51 and extends along the edge of the interface 512. The shield 52 is used to contact and cooperate with the outer wall of the external equipment.

[0077] The shielding member 52 is disposed on the cover wall 51. The connection method between the shielding member 52 and the cover wall 51 can be, but is not limited to, adhesive bonding, fastener connection, snap-fit ​​connection, etc. The shielding member 52 extends along the edge of the mating interface 512. Here, the shielding member 52 can extend along the edge of the mating interface 512 in a non-complete ring shape (e.g., Figures 6-8 As shown, Figure 8 for Figure 7 The enlarged structural diagram at point A in the middle circle shows that the shielding member 52 is located on the peripheral wall of the cover wall 51, and the bottom of the shielding member 52 is an annular break. It can also be extended into a complete ring (e.g., Figures 9-11 As shown, where Figure 11for Figure 10 (The middle circle shows an enlarged structural diagram at point B). Here, the ring can be, but is not limited to, a circular ring or a square ring.

[0078] Optionally, the shielding member 52 can be made of an elastic material to improve the contact effect, such as, but not limited to, rubber, silicone, etc.; Optionally, the shielding member 52 can be made of a shape with a certain deformability to improve the contact effect, for example, the cross-sectional shape of the shielding member 52 parallel to the contact direction can be circular, U-shaped, etc.

[0079] The shield 52 is used to contact and engage with the outer wall of the external device. Therefore, when charging the external device is required, the shield 52 of the protective cover 50 first contacts and engages with the outer wall of the external device, and then the charging connector 351 extends from the interface 512 and plugs into the charging port on the external device. During charging, the shield 52 blocks the gap between the cover 51 and the outer wall of the external device; specifically, it blocks the gap between the edge of the interface 512 and the charging panel 91. This makes it easier for the electrical connection between the charging connector 351 and the charging port to be protected from rain or ultraviolet radiation, greatly reducing the risk of water ingress and aging, and improving the service life of the charging plug assembly 30.

[0080] In some embodiments, such as Figure 9 and Figure 12 As shown, Figure 12 This is a top view of the protective cover 50 according to other embodiments of the present invention, wherein the shielding member 52 protrudes from the outer wall surface of the cover wall 51. In other words, the shielding member 52 is at least partially located on the side of the cover wall 51 facing away from the receiving space 511. This allows the protruding portion of the shielding member 52 to contact the outer wall of the external device, eliminating the need for the external device to extend into the cover wall 51. This helps reduce the risk of interference and impact, and prevents the external device from bringing rainwater into the receiving space 511.

[0081] According to some embodiments of this utility model, such as Figures 6-8 and Figures 10-13 As shown, Figure 13 yes Figure 12 In the cross-sectional view along the direction shown by line CC, the shield 52 is provided with a water guide channel 53. The water guide channel 53 can guide the water flow between the cover wall 51 and the external equipment in rainy or snowy weather, so as to reduce the risk of water flow between the external equipment and the shield 52, and between the cover wall 51 and the shield 52, and further reduce the risk of water ingress.

[0082] In some embodiments, such as Figures 6-8 and Figures 10-13As shown, the interface 512 is located on the side wall of the cover 51 on the side of the first direction F1. The water guide channel 53 includes a first channel segment 531, which is located on the top of the shield 52 and extends along the second direction F2, which intersects with the first direction F1. At least one end of the first channel segment 531 in the second direction F2 extends to the edge of the shield 52.

[0083] The first direction F1 and the second direction F2 can be horizontal or non-vertical directions forming a certain angle with the horizontal direction. The first direction F1 and the second direction F2 can be perpendicular to each other or form a certain angle. For example, the first direction F1 can be a front-back direction, and the second direction F2 can be a left-right direction. The interface 512 is provided on the side wall of the cover 51 on the side of the first direction F1, so that the cover 51 and the external equipment can be arranged and sealed together along the first direction F1.

[0084] Specifically, the first groove 531 is located at the top of the shield 52. When rainwater falls down onto the shield 52, it can enter the first groove 531 at the top and flow along the first groove 531 in the second direction F2 to the edge of the shield 52, making it difficult for water to flow to external equipment or between the cover 51 and the shield 52, thus effectively improving the waterproof effect.

[0085] In some embodiments, continue to refer to Figures 6-8 and Figures 10-13 The water guide channel 53 also includes a second channel segment 532, which is located on the side of the shield 52 and extends in the vertical direction. The second channel segment 532 is connected to the first channel segment 531.

[0086] The second groove segment 532 extends in the vertical direction. Here, the second groove segment 532 can be perpendicular to the vertical direction or at a certain angle to the vertical direction.

[0087] In embodiments where one end of the first channel segment 531 extends to the edge of the shielding member 52 and the other end does not extend to the edge of the shielding member 52, the water guide channel 53 may include a second channel segment 532, which may communicate with the end of the first channel segment 531 located at the edge of the shielding member 52. In some embodiments where both ends of the first channel segment 531 extend to the edge of the shielding member 52, the water guide channel 53 may include a second channel segment 532 and the second channel segment 532 communicates with one end of the first channel segment 531. The water guide channel 53 may also include two second channel segments 532, each communicating with one end of the first channel segment 531.

[0088] The water flow received by the first channel 531 can flow downwards along the second channel 532 for drainage. The first channel 531 and the second channel 532 can restrict the water flow path and improve the waterproofing effect.

[0089] In some specific embodiments, such as Figure 7 and Figure 8 As shown, the water guide channel 53 is composed of a first channel segment 531 and two second channel segments 532, forming an n-shaped channel; in other specific embodiments, such as Figures 10-13 As shown, the water guide channel 53 is composed of a first channel segment 531, two second channel segments 532 and a third channel segment 533. The third channel segment 533 extends along the second direction F2 and its two ends are respectively connected to the lower ends of the second channel segments 532. The water guide channel 53 is formed into a U-shaped channel. The shielding member 52 can be formed into a ring along the periphery of the interface 512, which has a better shielding effect on the charging connection.

[0090] According to some embodiments of this utility model, such as Figure 8 , Figure 11 and Figure 13 As shown, the shielding member 52 includes a first flange 521, a second flange 522, and a connecting portion 523. The first flange 521 extends along the edge of the interface 512 and connects to the cover wall 51. The second flange 522 is spaced apart from the first flange 521 in the through direction of the interface 512 (such as the first direction F1), and the second flange 522 is used for sealing contact with external equipment. The connecting portion 523 connects the first flange 521 and the second flange 522. The first flange 521, the second flange 522, and the connecting portion 523 cooperate to define a water guide groove 53, which is located on the side of the connecting portion 523 facing away from the center of the interface 512.

[0091] A flange (such as the first flange 521 and the second flange 522) refers to a flange that extends along the edge of the interface 512 and has a certain width perpendicular to its own extension direction and perpendicular to the penetration direction of the interface 512, so that the flange can form a mating surface with a certain area, and the mating surface can contact the cover wall 51 or external equipment.

[0092] The connection between the first flange 521 and the cover wall 51 increases the sealing area between the shielding member 52 and the cover wall 51; the contact and cooperation between the second flange 522 and the external equipment increases the sealing area between the shielding member 52 and the external equipment, thereby improving the shielding effect of the shielding member 52.

[0093] Furthermore, the connecting part 523 connects the first flange 521 and the second flange 522, so that the opposing surfaces of the first flange 521 and the second flange 522, and the side of the connecting part 523 facing away from the center of the interface 512, form the wall of the water guide groove 53, thus defining the water guide groove 53. The structure of the water guide groove 53 is simple.

[0094] In some embodiments, such as Figures 6-13As shown, the protective cover 50 also includes a pressure strip 54, and a first flange 521 is sandwiched between the pressure strip 54 and the cover wall 51. Fasteners are inserted through the pressure strip 54, the first flange 521 and the cover wall 51 to connect the pressure strip 54, the first flange 521 and the cover wall 51.

[0095] The pressure strip 54 can be made of, but is not limited to, stainless steel, aluminum alloy, etc. Fasteners can be, but are not limited to, bolts, screws, clips, etc. By setting fasteners, the first flange 521 and the cover wall 51 can be locked together, increasing the force between the first flange 521 and the cover wall 51 and improving the sealing effect. The pressure strip 54 can reduce wear on the first flange 521 caused by fasteners, increasing the service life of the first flange 521 and reducing the risk of water ingress between the shield 52 and the cover wall 51.

[0096] According to some embodiments of this utility model, such as Figure 8 and Figure 11 As shown, the edge of the interface 512 is provided with an outward flange 513, which is perpendicular to the through direction of the interface 512 (i.e., perpendicular to the first direction F1). The outward flange 513 is located on the side of the shield 52 near the center of the interface 512.

[0097] The outer flange 513 refers to a structure that protrudes relative to the interface 512 toward the direction of the external device, such that at least part of the outer flange 513 is located within the space enclosed by the shield 52.

[0098] By setting the outer flange 513, a bending path is formed from the gap between the first flange 521 and the cover wall 51 to the interface 512. Even if a gap is formed between the first flange 521 and the cover wall 51, causing water to flow from the first flange 521 and the cover wall 51 to the interface 512, it needs to cross the outer flange 513 to flow to the interface 512, further reducing the risk of water ingress at the interface 512.

[0099] The shape of the outward flange 513 can be flexibly set, for example, in some specific embodiments, such as... Figure 8 As shown, the outer flange 513 bends and extends backward toward the shielding member 52 in a direction away from the cover wall 51. In other words, the outer flange 513 is formed as an L-shaped flange.

[0100] The L-shaped outer flange 513 has a better blocking effect on water flow, making it less likely for water leaking between the first flange 521 and the cover wall 51 to cross the outer flange 513 and flow to the joint 512, thus further improving the waterproof effect.

[0101] According to some embodiments of this utility model, such as Figure 7 and Figures 9-10As shown, the protective cover 50 also includes a protective curtain 55, which is located at the interface 512 and is used to cover and open the interface 512.

[0102] The protective curtain 55 can be, but is not limited to, roller shutters, waterproof cloth, sliding doors, etc. It can not only serve as a shield, but also move by rolling or moving to open the interface 512.

[0103] By setting up the protective curtain 55, when the protective cover 50 is not connected to external equipment, the protective curtain 55 can block the interface 512, preventing rainwater and other fluids from directly entering the receiving space 511 through the interface 512, and also preventing sunlight from directly shining into the receiving space 511 through the interface 512, thus improving the protective effect of the protective cover 50 when not charging. When charging is required, the protective cover 50 is sealed to the outer wall of the external equipment, and the protective curtain 55 can be opened to allow the interface 512 to be connected to the external equipment for charging.

[0104] In some embodiments, continue to refer to Figure 7 , Figures 9-10 As shown, the cover wall 51 may be provided with multiple interfaces 512, and the protective curtains 55 at at least two interfaces 512 are integral pieces.

[0105] Therefore, the integrated protective curtain 55 can be opened and closed by the same drive structure, realizing the simultaneous opening and closing of multiple interfaces 512, improving operating efficiency and reducing the number of drive structures, thereby reducing costs and weight.

[0106] In some specific embodiments, such as Figure 9 As shown, the cover wall 51 is provided with a clearance opening 514, which is recessed or penetrates in the direction away from external equipment. The protective curtain 55 is also used to open and close the clearance opening 514.

[0107] The clearance opening 514 can be used to avoid interference between the protective curtain 55 and the upper structure of the component used to place the external device (such as the seating frame 20), so as to prevent the protective curtain 55 from interfering with the aforementioned structure and affecting the fit between the protective cover 50 and the external device. For example, the seating frame 20 may be provided with a guide component 21, which is used to guide and position the external device during the placement process and to limit the external device after placement. The clearance opening 514 can avoid the guide component 21, so that the charging panel 91 of the external device can make sealed contact with the shielding member 52 of the protective cover 50.

[0108] In addition, the protective curtain 55 is also used to open and cover the clearance opening 514 so that when the protective cover 50 is not in contact with external equipment, the protective curtain 55 can block the clearance opening 514 to prevent water from entering the receiving space 511 through the clearance opening 514, and can open the clearance opening 514 when the protective cover 50 needs to be in contact with external equipment to avoid interference with the guide assembly 21.

[0109] It should be noted that the protective curtain 55 used to open and cover the clearance opening 514 and the protective curtain 55 used to open and cover the mating interface 512 can be an integral part or separate parts.

[0110] In some embodiments of this utility model, such as Figures 9-10 and Figures 12-13 As shown, the protective cover 50 also includes a positioning structure 56, which is disposed on the cover wall 51 and is used to detect the engagement status between the protective cover 50 and the external equipment. The protective curtain 55 is configured to open the interface 512 when the protective cover 50 and the external equipment are in the correct engagement position.

[0111] For example, in embodiments including the shield 52, the shield 52 being in contact with the external device indicates that the protective cover 50 is properly engaged with the external device. In embodiments without the shield 52, the protective cover 50 being properly engaged with the external device is indicated by the distance between the cover wall 51 and the outer wall of the external device being less than or equal to a set distance.

[0112] The positioning structure 56 detects whether the protective cover 50 and the external equipment are properly matched, and ensures that the protective curtain 55 opens the interface 512 when the protective cover 50 and the external equipment are properly matched. This prevents water from entering the interface 512 when the protective curtain 55 opens the interface 512 when the protective cover 50 and the external equipment are not properly matched, thus further improving the rainproof effect.

[0113] The specific structure and detection method of the positioning structure 56 can be flexibly set according to the actual situation. For example, the positioning structure 56 can detect whether the protective cover 50 and the external equipment are properly matched by infrared detection, contact detection, ultrasonic detection and other methods.

[0114] In some embodiments, such as Figure 10 and Figure 13 As shown, the positioning structure 56 includes a probe 561, and the protective curtain 55 is configured to open the interface 512 when the probe 561 is in contact with an external device. In other words, when the probe 561 is in contact with the external device, it indicates that the protective cover 50 is properly engaged with the external device. Detecting the engagement through contact between the probe 561 and the external device provides higher accuracy and is unaffected by factors such as weather.

[0115] In some specific embodiments, the cover wall 51 is provided with a mounting base 562, and the positioning structure 56 is mounted on the mounting base 562 and is communicatively connected to the protective curtain 55 (wired or wireless connection). When the probe 561 comes into contact with an external device, the probe 561 is squeezed, which triggers the positioning structure 56, and the protective curtain 55 opens the interface 512 when the positioning structure 56 is triggered.

[0116] In some embodiments, such as Figure 9 and Figure 10 As shown, the cover wall 51 is provided with multiple interfaces 512, the positioning structure 56 is located between two adjacent interfaces 512, and the protective curtain 55 is provided with a clearance notch 551 for avoiding the positioning structure 56.

[0117] During the movement of the protective curtain 55, the positioning structure 56 can move relative to the clearance gap 551 to close the interface 512, and the positioning structure 56 can also move relative to the outside of the clearance gap 551 to open the interface 512. This prevents the positioning structure 56 from interfering with the movement of the protective curtain 55, and the protective curtain 55 can also provide shielding around the interface 512 and the positioning structure 56. The area of ​​the protective curtain 55 can be larger to improve the shielding effect on the interface 512.

[0118] In addition, there are multiple interfaces 512, and the positioning structure 56 is located between two adjacent interfaces 512. This allows the positioning structure 56 to detect the sealing condition at the two interfaces 512, improving the detection accuracy and making the components on the cover wall 51 more compact.

[0119] According to some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the cover wall 51 includes a support frame 515, a top plate 516, and multiple side plates 517. The top plate 516 is located on the upper side of the support frame 515 and connected to the support frame 515, and the multiple side plates 517 are located on multiple sides of the support frame 515 and connected to the support frame 515.

[0120] The support frame 515 refers to a frame structure formed by connecting multiple beams. These beams can be interconnected to improve the stability of the support frame 515. The top plate 516 and side plates 517 can be made of materials such as stainless steel or aluminum alloy to block the open areas on the support frame 515, thereby achieving the shielding and protection effect of the enclosure wall 51 on the components inside the accommodating space 511.

[0121] In addition, the top plate 516 and multiple side plates 517 are connected to the support frame 515 from the top and sides respectively, so that the bottom of the cover wall 51 can be opened, that is, the receiving space 511 has a lower opening, so that the cover wall 51 can be covered on the charging plug assembly 30 through the lower opening, avoiding interference and making assembly easier.

[0122] In some embodiments of this utility model, such as Figure 6 and Figure 7 As shown, the enclosure 51 may be provided with at least one inspection door 57. By opening and closing the inspection door 57, maintenance personnel can enter the housing space 511 to facilitate the inspection and maintenance of internal components such as the charging plug-in assembly 30.

[0123] In some specific embodiments, such as Figure 6 and Figure 7 As shown, the side walls of the cover 51 along the second direction F2 are respectively provided with inspection doors 57, so that inspection can be carried out through different inspection doors 57 according to the fault area, making the inspection operation more convenient.

[0124] In some embodiments of this utility model, such as Figure 10 and Figure 12 As shown, the protective cover 50 also includes an alarm 518, which can issue an alarm message when components such as the charging plug-in assembly 30 malfunction. For example, the alarm 518 can issue an alarm message through at least one of the following methods: light, voice, etc.

[0125] In some embodiments of this utility model, such as Figure 7 As shown, the protective cover 50 also includes an electrical control box 58, which is located within the receiving space 511 and connected to the cover wall 51. On the one hand, this facilitates the connection of the electrical control box 58 with other components of the charging device 2 and makes maintenance of the electrical control box 58 easier; on the other hand, during the production process, the electrical control box 58 can be installed into the cover wall 51 first, and the charging plug assembly 30 can be assembled before the protective cover 50 is placed over the charging plug assembly 30, making the production of the charging device 2 easier.

[0126] In some embodiments of this utility model, such as Figures 3-5 As shown, the charging device 2 also includes a charging base 10 and a moving platform 40. The moving platform 40 is movably mounted on the charging base 10, the charging plug assembly 30 is mounted on the moving platform 40, and the protective cover 50 is mounted on the moving platform 40. The moving platform 40 is movable along the first direction F1 to move the protective cover 50 and the charging plug assembly 30 closer to and away from the external device.

[0127] The charging plug-in assembly 30 can be fixedly installed on the mobile platform 40 by fasteners, welding, or other means, or it can be movably installed on the mobile platform 40 by means of guide rails or other structures. The protective cover 50 and the mobile platform 40 can be connected by fasteners, connectors 59, etc. For example, the protective cover 50 and the mobile platform 40 can be connected by multiple connectors 59 spaced apart along the circumference of the mobile platform 40. The connectors 59 are bent plates, one part of which is connected to the cover wall 51 of the protective cover 50 by fasteners, and the other part of which is connected to the mobile platform 40 by fasteners.

[0128] The charging base 10 provides support and guidance for the movement of the mobile platform 40 and its components. For example, the charging base 10 may be equipped with a guide rail, and the mobile platform 40 may move along the guide rail along a straight or curved path. Specifically, the external device can be positioned on one side of the charging base 10 in the first direction F1. When the external device is positioned, the mobile platform 40 can move in the first direction F1 to move the protective cover 50 and the charging plug assembly 30 closer to and away from the external device. The mobile platform 40 moves the protective cover 50 and the charging plug assembly 30 closer to the external device, allowing the shield 52 of the protective cover 50 to contact and engage with the external device. The interface 512 can be directly opposite the charging panel 91 of the external device, and the charging connector 351 of the charging plug assembly 30 can pass through the interface 512 and be plugged into the charging port on the charging panel 91 for charging. After charging is completed, the mobile platform 40 moves the protective cover 50 and the charging plug assembly 30 away from the external device to avoid interfering with the movement of the external device.

[0129] By setting up the charging base 10 and the moving platform 40, the protective cover 50 can initially cooperate with the external device to achieve shielding and protection before the charging plug assembly 30 is plugged into the external device for charging. This reduces the effect of water ingress into the charging plug structure and makes it easier for the protective cover 50 to cooperate with the external device.

[0130] In some embodiments, such as Figures 4-8 and Figures 10-11 As shown, the cover wall 51 is provided with two docking ports 512, which are arranged along a second direction F2, intersecting with the first direction F1. The charging connector 351 has a first position and a second position on the moving platform 40 that can be switched along the second direction F2. The first position corresponds to one of the two docking ports 512, and the second position corresponds to the other of the two docking ports 512.

[0131] For example, the two interfaces 512 are the first pair of interfaces and the second pair of interfaces, respectively. The first position corresponds to the first pair of interfaces, and the second position corresponds to the second pair of interfaces. The charging connector 351 can extend from the first pair of interfaces in the first position and be plugged into the charging port corresponding to the first pair of interfaces on the external device for charging. After the charging connector 351 moves to the second position, it can extend from the second pair of interfaces and be plugged into the charging port corresponding to the second pair of interfaces on the external device for charging.

[0132] In some related technologies, external devices typically employ dual-circuit charging. After one power source is fully charged, the charging gun needs to be manually unplugged and plugged into the charging socket of the other power source, which is time-consuming and laborious. In this application, by switching the charging connector 351 between a first position and a second position, the charging connector 351 can selectively extend from two mating interfaces 512, thereby mating with different charging ports of the external device and charging different circuits of the external device. Therefore, the charging device 2 can meet the multi-circuit charging needs of external devices.

[0133] Furthermore, during use, the mobile platform 40 can first move the protective cover 50 and the charging plug assembly 30 along the first direction F1 to approach the external device, so that the two docking ports 512 on the protective cover 50 are respectively aligned with the two charging panels 91 of the external device; then, after the charging connector 351 has finished charging by plugging into the charging port on one charging panel 91 at the first position, it can be moved to the second position to plug into the charging port on the other charging panel 91. During the process of switching the charging ports, there is no need to move the protective cover 50 again, which is conducive to improving charging efficiency and protection effect.

[0134] The switching method of the charging connector 351 between the first and second positions can be flexibly set. For example, the switching can be achieved by moving the entire charging plug assembly 30 relative to the moving platform 40, or by moving a part of the charging plug assembly 30 relative to another part.

[0135] Specifically, in some embodiments, the mobile stage 40 is provided with a second direction translation guide rail, and the charging plug-in assembly 30 moves on the second direction translation guide rail to switch the charging connector 351 between a first position and a second position.

[0136] The second-direction translation guide rail extends along the second direction F2. The charging plug-in assembly 30 cooperates with the second-direction translation guide rail and can move along the second-direction translation guide rail to achieve movement in the second direction F2, making the position switching control of the charging connector 351 more flexible.

[0137] In other embodiments, such as Figure 4 and Figure 5As shown, the charging plug-in assembly 30 includes a first moving module 31 and a second moving module 32. The first moving module 31 is disposed on the moving platform 40, and the charging connector 351 is disposed on the second moving module 32. The second moving module 32 is movably mounted on the first moving module 31 along the second direction F2, so that the charging connector 351 can switch between a first position and a second position.

[0138] The position switching of the charging connector 351 has no impact on the movement of the charging plug assembly 30 relative to the moving platform 40, making the position and installation structure design of the charging plug assembly 30 relative to the moving platform 40 more flexible, which is conducive to more reliable installation and more flexible position adjustment.

[0139] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the mobile stage 40 includes a first-direction translational guide rail 41, and the charging plug-in assembly 30 moves on the first-direction translational guide rail 41 to realize the plugging and unplugging of the charging connector 351 and the charging port. In some specific embodiments, such as Figure 5 As shown, the first moving module 31 cooperates with the first direction translation guide rail 41.

[0140] The first-direction translation guide rail 41 extends along the first direction F1. The charging plug-in assembly 30 cooperates with the first-direction translation guide rail 41 and is movable along the first-direction translation guide rail 41 to achieve movement in the first direction F1. After adjusting the position of the charging connector 351 in the second direction F2, the charging connector 351 is plugged into and unplugged from the charging port by translating in the first direction F1, which improves the centering.

[0141] In some embodiments, such as Figure 4 and Figure 5 As shown, the charging plug-in assembly 30 includes a first moving module 31, a second moving module 32, and a third moving module 33. The first moving module 31 is movably mounted on the moving platform 40 along a first direction F1, the second moving module 32 is movably mounted on the first moving module 31 along a second direction F2, and the third moving module 33 is movably mounted on the second moving module 32 along a third direction F3. The charging connector 351 is disposed on the third moving module 33. The first direction F1, the second direction F2, and the third direction F3 intersect each other.

[0142] The first mobile module 31 can be directly or indirectly mounted on the mobile station 40, the second mobile module 32 can be directly or indirectly mounted on the first mobile module 31, the third mobile module 33 can be directly or indirectly mounted on the second mobile module 32, and the charging connector 351 can be directly or indirectly mounted on the third mobile module 33. For example... Figure 4 and Figure 5The plug-in module 35 shown includes a charging connector 351, and the plug-in module 35 is indirectly mounted to the third moving module 33 through the oscillation module 34.

[0143] 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 third 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 external devices, enabling charging of multiple external devices.

[0144] 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-loop external device. 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-loop external device. 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 charging connector 351, allowing the charging connectors 351 on the two third moving modules 33 to connect to two charging panels 91 respectively, thus achieving charging of the dual-loop external device.

[0145] By using the first moving module 31, the second moving module 32, and the third moving module 33, the control accuracy of the movement displacement of the charging connector 351 along the first direction F1, the second direction F2, and the third direction F3 can be improved. This enhances the control accuracy of the position of the charging connector 351, enabling it to accurately connect to the corresponding charging panel 91. The insertion and removal accuracy of the same charging connector 351 with one charging panel 91 or alternating with multiple charging panels 91 is higher, and the success rate is higher, facilitating automatic plug-and-play charging. It also allows the same charging connector 351 to be alternately plugged into different charging panels 91 of external devices, meeting the charging needs of different circuits in external devices.

[0146] like Figures 1-4As 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, for example, to a charging base 10. The seating frame 20 is used to place external devices. Since the charging device 2 according to an embodiment of the present invention has the aforementioned beneficial technical effects, the charging system 1 according to an embodiment of the present invention can provide protection for the charging plug assembly 30, achieving protection functions such as rain and sun protection, which is beneficial to improving the service life of the charging plug assembly 30 and improving the reliability of the charging connection between the charging plug assembly 30 and the external device.

[0147] In some related technologies, tower cranes are typically used to hoist external equipment to the charging equipment. However, this requires repeated adjustments of the external equipment's position by the tower crane to align it with the charging equipment before lowering it down. This results in excessively long hoisting times, long on-site alignment times (aligning the external equipment with the charging equipment), and low charging efficiency for the external equipment.

[0148] The mounting frame 20 of this application restricts the mounting position of external equipment. That is, by placing external equipment on the mounting frame 20, the external equipment can be quickly hoisted onto the mounting frame 20 without repeatedly adjusting the position of the external equipment before putting it down. This shortens the on-site alignment time, facilitates installation, and enables the external equipment to be quickly placed in the battery swapping station. It also ensures high charging efficiency for the external equipment and eliminates the need to build other devices for placing external equipment in the battery swapping station, reducing the construction cycle and allowing for rapid commissioning.

[0149] 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 external device through the guide slope during the process of placing the external device on the seating frame 20, so that the external device 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 external device and improve the placement accuracy of the external device.

[0150] like Figures 1-4 As shown, the charging system 1 according to an embodiment of the present invention includes a charging device 2 according to an embodiment of the present invention, and the external device is a box-type power supply 90, which is a replaceable power supply for electric vessels. This enables electric vessels to swap batteries, reducing charging and battery swapping waiting time; and 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.

[0151] The charging system 1 according to some specific embodiments of the present invention is described in detail below with reference to the accompanying drawings. It is worth understanding that the following description is merely illustrative and should not be construed as limiting the present invention.

[0152] like Figures 1-8 As shown, the charging system 1 according to the first specific embodiment of this utility model is used for charging an external device, which is a box-type power supply 90 for an electric ship. The charging system 1 includes a seating frame 20 and a charging device 2. The seating frame 20 is connected to the charging device 2 and is used to place the box-type power supply 90. The box-type power supply 90 has two charging panels 91, and each charging panel 91 has a charging port. The charging device 2 includes a charging base 10, a moving platform 40, a charging plug-in assembly 30, a power transmission cable 61, and a protective cover 50.

[0153] The charging base 10 includes a charging frame and two guide rails. The guide rails extend along a first direction F1, and the two guide rails are spaced apart along a second direction F2 and placed on the charging frame. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other, and the third direction F3 is the vertical direction.

[0154] The mobile platform 40 is movably mounted on the guide rail of the charging base 10 along the first direction F1 via rollers. The cover wall 51 of the protective cover 50 covers the mobile platform 40 and is fixedly connected to the mobile platform 40 via a connector 59. The protective cover 50 has two square mating interfaces 512 on the side wall facing the seating frame 20 in the first direction F1, and the two mating interfaces 512 are spaced apart along the second direction F2. A positioning structure 56 is provided between the two mating interfaces 512. A protective curtain 55 is provided inside the cover wall 51. The protective curtain 55 is a roller shutter door and is movable along the third direction F3 to open and cover the mating interfaces 512. At each mating interface 512, the cover wall 51 forms an outward flange 513, and a blocking member 52 extends along the edge of the mating interface 512 and is arranged around the outward flange 513. The shield 52 has an N-shaped structure with its opening facing downwards. The first flange 521 of the shield 52 is fixedly connected to the cover wall 51 by a pressure strip 54 and fasteners. The second flange 522 of the shield 52 is used to contact and cooperate with the charging panel 91 of the box-type power supply 90. The shield 52 forms a water guide channel 53, which consists of a first channel section 531 and two second channel sections 532, used to guide rainwater and other water flow downwards, reducing the risk of water entering between the cover wall 51 and the shield 52, and between the box-type power supply 90 and the shield 52. The cover wall 51 has two opposite side walls in the second direction F2, respectively, with an inspection door 57. An electrical control box 58 is installed inside the cover wall 51, and an alarm 518 is installed on the top of the cover wall 51.

[0155] The charging plug-in assembly 30 is located within the receiving space 511 of the protective cover 50. The charging plug-in assembly 30 is movably mounted on the mobile platform 40 and used to connect to the box-type power supply 90 for charging the box-type power supply 90. A power transmission cable 61 is electrically connected to the charging plug-in assembly 30 to supply power to the charging plug-in assembly 30. The power transmission cable 61 is supported by the casters of the first support assembly 62 on the walking surface and is also supported by the rollers and rotating rods of the second support assembly 63 on the charging plug-in assembly 30 to accommodate the movement of the power transmission cable 61 during plugging / unplugging and attitude adjustment processes.

[0156] 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 plugging module 35 has a charging connector 351 on its connector panel. The first moving module 31 is movably mounted on the moving platform 40 along a first direction F1 via a first direction translation guide rail 41 and a slider. The second moving module 32 is movably mounted on the first moving module 31 along a second direction F2 via a second direction translation guide rail and a slider. The third moving module 33 is movably mounted on the second moving module 32 along a third direction F3 via a third direction translation guide rail and a slider. The tilting module 34 is located between the third moving module 33 and the plugging module 35, and can adjust the angle of the connector panel of the plugging module 35.

[0157] 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 512 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 positioning structure 56 abuts against the box-type power supply 90, completing the initial positioning. At this time, the shielding part 52 of the protective cover 50 contacts and engages with the box-type power supply 90, the moving platform 40 stops moving, and the protective curtain 55 opens the interface. 512; The charging plug-in assembly 30 is close to the external device, and the accuracy of relative position and relative angle detection is higher. Therefore, the relative position and relative angle between the charging connector 351 and the charging port can be identified by means of point laser ranging, 2D visual feature hole positioning, etc., with the help of the identification component. According to the identification result, 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 charging connector 351 is accurately aligned with the charging port on the corresponding charging panel 91 through one of the interfaces 512 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 charging connector 351 from the charging port. The second moving module 32 moves along the second direction F2 to align the charging connector 351 with the charging port on the charging panel 91 corresponding to another interface 512. 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 connect the charging connector 351 to the charging port for charging.

[0158] After charging is complete, the charging connector 351 is separated from the charging port 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. The protective curtain 55 covers and seals the interface 512. At this time, the box-type power supply 90 can be transferred by hoisting.

[0159] In the above embodiments, the charging plug-in module 35 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 pins of the charging panel 91 experience less wear, leading to a longer equipment lifespan and more stable and reliable performance. The modular design, with the seating frame 20 as one module and the charging device 2 as another, allows for quick on-site connection via fasteners, eliminating the need for on-site alignment. This facilitates installation, rapid deployment, and reduces the construction cycle, enabling rapid operation. The protective cover 50's shielding component 52 first contacts and engages with the box-type power supply 90, and then the protective curtain 55 opens the interface 512, allowing the charging connector 351 to extend and plug into the charging port of the charging panel 91. This provides excellent rain protection, eliminates the risk of leakage and short circuits, physically isolates the device from rain and snow, and ensures 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 connector panel 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 insertion / removal 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 the charging connector 351 within 0.3mm on one side, resulting in high insertion / removal accuracy and a high success rate.

[0160] like Figures 9-13 As shown, the charging system 1 according to the second specific embodiment of the present invention differs from the charging system 1 of the first specific embodiment in that the shielding member 52 on the protective cover 50 is U-shaped, and the water guide channel 53 is composed of a first channel segment 531, two second channel segments 532 and a third channel segment 533, which better prevents water from entering the interface 512.

[0161] Other configurations and operations of the charging system 1 according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
