[0047] In this application, "multiple" means two or more (including two).

[0048] 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.

[0049] The external equipment mentioned in the embodiments of 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 enclosure. It has the characteristics of flexible deployment, strong environmental adaptability, and safety and reliability. For example, external equipment may include containerized battery power supplies, box-type UPS power supplies, trolley case-type energy storage mobile power supplies, and electrical box-type intelligent power supplies.

[0050] 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.

[0051] External equipment 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, external equipment can provide power input to ensure normal operation or act as a backup power source to guarantee the ship's endurance and emergency response capabilities. In power systems, it can improve the reliability and stability of the power grid, ensuring the continuity of power supply.

[0052] 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, and the external device can be a mobile device. The external device is detachable. After the ship docks, the external device can be disassembled by hoisting and then transported to the battery swapping station for charging by the charging system.

[0053] In related technologies, the charging connector of the charging device and the socket of the external device have a large gap during the docking process, and the relative position and relative angle are not easy to control. This makes the docking operation difficult and inaccurate, and docking failure is easy to occur, resulting in low charging efficiency and damage to the docking structure such as the charging connector and socket.

[0054] Based on this, this application proposes a charging device for charging external devices. The charging device includes: a base assembly, a charging plug assembly, and a charging movable base. The charging plug assembly is provided with a charging connector for plugging and unplugging with a charging port on an external device to charge the external device. The charging plug assembly is mounted on the charging movable base, which is mounted on the base assembly and movable along a first direction to drive the charging connector to plug and unplug with the charging port along the first direction. The charging movable base is provided with a charging position switching guide rail, and the charging plug assembly is mounted on the charging movable base and movable along the charging position switching guide rail in a second direction to cooperate with multiple sets of charging ports on the external device. The second direction intersects the first direction.

[0055] In the charging device described above, when charging an external device is required, the charging plug assembly can move along the charging position switching guide in the second direction, switching between different charging positions to achieve accurate pairing with different sets of charging ports on the external device. The charging movable seat drives the charging plug assembly to move along the first direction, enabling the charging plug assembly to connect and charge with the charging port of the external device. After charging is completed, it switches to the next charging position under the action of the charging position switching guide, allowing the charging plug assembly to pair and connect with another set of charging ports on the external device. This solution enables mechanized docking and charging of multiple charging and discharging circuits of the external device, improving charging efficiency, reducing docking failure rates compared to manual methods, and enhancing charging reliability.

[0056] The charging device in this embodiment is used in a charging system, which can be used to charge an energy storage system such as a box-type power supply. The energy storage system can be, but is not limited to, ships, spacecraft, etc., wherein the spacecraft can include airplanes, rockets, space shuttles, and spacecraft.

The specific structure of the base assembly 3 is not limited. For example, the base assembly 3 can be composed of multiple side beams connected end to end, or the base assembly 3 can be composed of multiple beams that are arranged crosswise and connected, or it can be a flat plate structure, etc.

[0063] The charging mobile base 70 can be composed of multiple side beams connected end to end, or it can be composed of multiple beams that are arranged crosswise and connected, or it can be a flat plate structure, etc. The charging mobile base 70 moves along a first direction F1, which can be, but is not limited to, a straight line, a curve, or other path.

[0064] The charging position switching guide rail 80 is a guide rail component installed on the charging moving base 70. It can provide guidance for the movement of the charging plug-in assembly 30. The charging position switching guide rail 80 can extend along straight or curved paths. The charging position switching guide rail 80 can make the charging plug-in assembly 30 correspond and match one by one with the multiple charging ports 911 of the external device 90.

[0065] The charging plug-in assembly 30 refers to a component that can charge an external device 90 through charging plug-in. Charging plug-in refers to the process of inserting or removing the charging port 911 of the external device 90 during the charging process. For example, the charging connector 351 of the charging plug-in assembly 30 is inserted into or removed from the socket of the external device 90 to establish or disconnect the charging connection. This process involves mechanical connection, electrical connection and disconnection, communication interaction and safety protection mechanism, and is one of the operations of device charging.

[0066] The charging plug-in assembly 30 is movable along the charging position switching guide 80 in a second direction F2, which can be, but is not limited to, a straight line, a curve, or other path. For example, the second direction F2 and the first direction F1 can be arranged at an angle, such as the second direction F2 and the first direction F1 being arranged perpendicular to each other.

[0067] Reference Figure 1 The external device 90 can be a cuboid structure, with its length being the direction of its maximum dimension. The length direction of the external device 90 is defined as the first direction F1. A charging panel 91 can be arranged at one end of the external device 90 along its length. Multiple charging panels 91 can be provided on the external device 90. Each charging panel 91 can have a set of charging ports 911. The number of charging ports 911 in a set can be multiple. Each charging panel 91 is connected to a charging / discharging circuit inside the external device 90; that is, multiple charging panels 91 correspond to multiple charging / discharging circuits. The charging plug-in assembly 30 can be plugged into and cooperate with multiple charging ports 911 of one set of multiple sets of charging panels 91 in the external device 90. For example, refer to... Figure 1 The external device 90 is equipped with two charging panels 91, each charging panel 91 is equipped with multiple charging ports 911, and each charging panel 91 is connected to a charging and discharging circuit inside the external device 90. Thus, the external device 90 has dual channels. The charging plug-in assembly 30 can move on the charging moving base 70 to switch charging positions under the action of the charging position switching guide rail 80, thereby realizing the switching charging of dual channels.

[0068] 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 socket. 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.

[0069] According to the charging device 2 of this application embodiment, when an external device 90 needs to be charged, the charging plug-in assembly 30 can move along the charging position switching guide 80 in the second direction F2, switching between different charging positions to achieve accurate matching with multiple charging ports 911 of the external device 90. The charging movable seat 70 drives the charging plug-in assembly 30 to move along the first direction F1, enabling the charging plug-in assembly 30 to connect and charge with multiple charging ports 911 of the external device 90. After charging is completed, it switches to the next charging position under the action of the charging position switching guide 80, allowing the charging plug-in assembly 30 to pair and connect with another charging port 911 of the external device 90 for charging. This solution enables mechanized docking and charging of multiple charging ports 911 of the external device 90, improving charging efficiency, reducing docking failure rates compared to manual methods, and enhancing charging reliability.

[0070] In some embodiments of this application, reference is made to Figure 4 and Figure 5 The charging and plugging assembly 30 includes a moving module 301 and a plugging module 35. The moving module 301 is located on the charging moving base 70, and the plugging module 35 is located on the moving module 301. The moving module 301 can move along the charging position switching guide rail 80, and can form multiple charging positions in the second direction F2. The multiple charging positions are set to correspond one-to-one with the multiple sets of charging ports 911 of the external device 90.

[0071] The moving module 301 is a component used to drive the plug-in module 35 to move relative to the charging moving base 70. The movement includes, but is not limited to, linear movement, curved movement, and rotation along at least one direction. The plug-in module 35 can be a component that is directly connected to an external device 90.

[0072] When the plug-in module 35 moves to the vicinity of the charging port 911 of the external device 90, there may be a positional deviation between the plug-in module 35 and the charging port 911. Directly inserting the plug-in module 35 into the charging port 911 could easily damage the charging port 911. The moving module 301 can adjust the position between the plug-in module 35 and the charging port 911, ensuring that the plug-in module 35 and the charging port 911 are directly aligned and properly engaged, reducing the risk of damage to both. In other words, the moving module 301 can more precisely adjust the relative position of the plug-in module 35 and the external device 90, thereby allowing for more flexible adjustment of their relative orientation. This improves charging plug-in efficiency and accuracy, further reduces docking difficulty, lowers the risk of plug-in failure, and increases charging efficiency. It also reduces the risk of damage to the docking structure between the plug-in module 35 and the external device 90.

[0073] Furthermore, the moving module 301 can drive the plug-in module 35 to move along the charging position switching guide rail 80, thereby forming multiple charging positions in the second direction F2, providing power for the plug-in module 35 and one of the multiple charging ports 911 of the external device 90 to find and match, so that the plug-in module 35 can be plugged into and charged with the multiple charging ports 911 of the external device 90.

[0074] In the above technical solution, the moving module 301 can adjust the relative position of the plug-in module 35 and the external device 90, improving the alignment accuracy between the plug-in module 35 and the corresponding set of charging ports 911, thereby ensuring that the plug-in module 35 is directly facing the charging port 911. This improves the docking success rate between the charging plug-in assembly 30 and the charging port 911, and enhances the charging reliability of the charging device 2. The moving module 301 can also drive the plug-in module 35 to move along the charging position switching guide rail 80 to switch between different charging positions, allowing the plug-in module 35 to cooperate with different sets of charging ports 911. This enables the charging plug-in assembly 30 to be plugged into and charged through multiple sets of charging ports 911 of the external device 90, thereby improving charging efficiency.

[0075] In some embodiments of this application, reference is made to Figures 1 to 4 , Figure 6 and Figure 7 The charging device 2 includes a protective cover 50, which is mounted on the base assembly 3 and has a receiving space 511. The charging plug-in assembly 30 is located in the receiving space 511. The protective cover 50 is provided with multiple charging ports 512, and the multiple charging ports 512 and multiple charging positions correspond one-to-one, so that the plug-in module 35 passes through the charging port 512 and plugs into the charging port 911 of the external device 90 for charging.

[0076] The protective cover 50 can refer to a shell-shaped structural component that can serve a waterproof function, and can be made of, but is not limited to, plastic, metal, or composite materials.

[0077] The charging port 512 can refer to an opening on the protective cover 50 that communicates with the receiving space 511, allowing the plug-in module 35 to extend out and engage with the charging panel 91. The charging port 512 can penetrate the protective cover 50 along its wall thickness, enabling plugging and unplugging operations between components inside and outside the receiving space 511. The charging port 512 can be located at least at one location on the top wall and peripheral wall of the cover 51, for example... Figure 6 and Figure 7 As shown, the protective cover 50 includes multiple sidewalls, one of which, facing the external device 90, is provided with a charging port 512. The number of charging ports 512 corresponds to the number of charging positions, allowing the plug-in module 35 to extend through the corresponding charging port 512 when in the corresponding charging position. The shape of the charging port 512 can be, but is not limited to, rectangular, circular, or elliptical shapes, etc., and no specific limitations are imposed here.

[0078] In the above technical solution, the charging plug-in assembly 30 is located within the receiving space 511 formed inside the protective cover 50. Therefore, the protective cover 50 can protect the charging plug-in assembly 30, reducing the probability of short circuits or other malfunctions caused by contact with external rainwater, dust, etc., and also reducing the risk of damage from impacts. This improves the reliability of the charging plug-in assembly 30 and extends its service life. Multiple charging ports 512 allow the plug-in module 35 to extend and engage with the charging panel 91 after moving to the corresponding charging position, ensuring smooth plug-in charging. While ensuring that the plug-in module 35 can engage with multiple charging panels 91 for charging, this method also simplifies the structure of the protective cover 50 and reduces manufacturing difficulty.

[0079] In some embodiments of this application, the protective cover 50 includes a cover body 51 and a seal 52. The cover body 51 has a receiving space 511 and a charging port 512. The seal 52 is disposed on the cover body 51 and extends along the periphery of the charging port 512. The seal 52 is used for sealing and engaging with an external device 90.

[0080] The enclosure 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 enclosure 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 to allow the enclosure 51 to cover the charging plug assembly 30. The peripheral wall may be cylindrical or a prismatic shape composed of multiple flat side walls. Optionally, the enclosure 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 enclosure 51 may be, but is not limited to, high-strength low-carbon steel, aluminum alloy, stainless steel, composite materials (such as aluminum and insulation layers), etc.

[0081] The housing 51 may have one or more charging ports 512, which may be located on the same wall or on different walls. In embodiments with multiple charging ports 512, the charging plug-in assembly 30 may charge the external device 90 sequentially through the charging ports 512 or simultaneously through multiple charging ports 512.

[0082] A seal 52 is disposed on the cover 51. The connection method between the seal 52 and the cover 51 can be, but is not limited to, adhesive bonding, fastener connection, snap-fit ​​connection, etc. The seal 52 extends along the periphery of the charging port 512. Here, the seal 52 can extend along the periphery of the charging port 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 B shows that the seal 52 is located on the peripheral wall of the cover 51, and the bottom of the seal 52 is an annular fracture. It can also extend into a complete ring (e.g., Figures 8-10 As shown, where Figure 10 for Figure 9 (See the enlarged structural diagram at point C). Here, the ring can be, but is not limited to, a circular ring or a square ring.

[0083] Optionally, the seal 52 can be made of an elastic material to improve the sealing effect, such as, but not limited to, rubber, silicone, etc.; Optionally, the seal 52 can be made of a shape with a certain deformability to improve the sealing effect, for example, the cross-sectional shape of the seal 52 parallel to the contact direction can be circular, U-shaped, etc.

[0084] The seal 52 is used for a sealed fit with the external device 90. Therefore, when charging the external device 90 is required, the seal 52 of the protective cover 50 can first seal with the external device 90, and then the charging plug assembly 30 extends from the charging port 512 and plugs into the charging panel 91 of the external device 90 for charging. During charging, the seal 52 seals the gap between the cover 51 and the external device 90, specifically sealing the gap between the periphery of the charging port 512 and the charging panel 91. This prevents the electrical connection between the charging plug assembly 30 and the charging panel 91 from being exposed 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.

[0085] In the above technical solution, the cover 51 can shield and protect the charging plug assembly 30, achieving rain and sun protection functions. The seal 52 can improve the sealing between the charging panel 91 of the external device 90 and the cover 51, reducing the probability of rainwater, dust and other particles entering the interior of the cover 51. This can reduce the risk of failure of the charging plug assembly 30, which is conducive 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 90.

[0086] In some embodiments of this application, reference is made to Figures 6 to 13 The sealing element 52 is provided with a water guide groove 53, which includes a first groove segment 531 and a second groove segment 532. The first groove segment 531 is located on the top of the sealing element 52 and extends along the second direction F2. The second groove segment 532 is located on the side of the sealing element 52 and extends along the vertical direction F3. The second groove segment 532 is connected to the first groove segment 531. The vertical direction F3, the first direction F1, and the second direction F2 intersect each other.

[0087] The first direction F1 and the second direction F2 can be horizontal or non-vertical directions forming an angle with the horizontal. The first direction F1 and the second direction F2 can be perpendicular to each other or form an 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 charging port 512 is located on the side wall of the cover 51 on the side of the first direction F1, allowing the cover 51 and the external device 90 to be arranged and sealed together along the first direction F1. The vertical direction F3, the second direction F2, and the first direction F1 can be arranged at an angle to each other; for example, the vertical direction F3, the second direction F2, and the first direction F1 can be perpendicular to each other.

[0088] The water guide channel 53 can guide water flow during rain and snow to reduce the risk of water flowing to external equipment 90 or between the cover 51 and the seal 52, further reducing the risk of water ingress. Specifically, the first channel section 531 is located at the top of the seal 52. When rainwater falls onto the seal 52, it can enter the first channel section 531 at the top and flow along the first channel section 531 in the second direction F2 to the edge of the seal 52, making it difficult for water to flow to external equipment 90 or between the cover 51 and the seal 52, effectively improving the waterproof effect.

[0089] In some embodiments, continue to refer to Figure 6 , Figure 11 and Figure 13 The water guide channel 53 also includes a second channel segment 532, which is located on the side of the seal 52 and extends in the vertical direction. The second channel segment 532 is connected to the first channel segment 531.

[0090] 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.

[0091] In embodiments where one end of the first groove segment 531 extends to the edge of the seal 52 and the other end does not extend to the edge of the seal 52, the water guide channel 53 may include a second groove segment 532 that communicates with the end of the first groove segment 531 located at the edge of the seal 52. In some embodiments where both ends of the first groove segment 531 extend to the edge of the seal 52, the water guide channel 53 may include a second groove segment 532 that communicates with one end of the first groove segment 531. The water guide channel 53 may also include two second groove segments 532 that communicate with the two ends of the first groove segment 531, respectively.

[0092] 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.

[0093] In the above-mentioned technical solution, rainwater and other liquids around the seal 52 can be discharged through the water guide groove 53, which can reduce the risk of rainwater and other liquids remaining in the location of the seal 52 for a long time and causing the seal to fail. This is beneficial to improving the sealing reliability between the cover 51 and the charging panel 91, thereby improving the charging reliability of the charging device 2 to the external device 90.

[0094] In some embodiments of this application, reference is made to Figures 6 to 9 and Figure 13 The protective cover 50 includes a shield 55, which is closable and located at the charging port 512.

[0095] The shield 55 can be, but is not limited to, a roller shutter, waterproof cloth, sliding door, etc., which can not only serve as a shield, but also move by means of rolling or moving to open the charging port 512.

[0096] In the above technical solution, by setting up the shielding component 55, when the protective cover 50 is not sealed with the external device 90, the shielding component 55 can block the charging port 512, preventing rainwater and other fluids from directly entering the receiving space 511 through the charging port 512, and also preventing sunlight from directly shining into the receiving space 511 through the charging port 512, thus improving the rain and sun protection effect of the protective cover 50 when not charging. When charging is required, the protective cover 50 is sealed with the external device 90, and the shielding component 55 can open the charging port 512 to facilitate the connection and charging of the charging plug-in assembly 30 with the external device 90.

[0097] In some embodiments of this application, at least two of the multiple charging ports 512 have integrated shielding members 55. In the above technical solution, the integrated shielding members 55 can be driven to open and close by the same driving structure, realizing the simultaneous opening and closing of multiple charging ports 512, improving operating efficiency and reducing the number of driving structures, thereby reducing costs and weight.

[0098] In some embodiments of this application, reference is made to Figure 1 , Figure 2 and Figure 5 The base assembly 3 includes a charging base 10 and a moving platform 40. The charging base 10 has a moving guide rail 11. The moving platform 40 is mounted on the charging base 10 and moves along the moving guide rail 11 to approach or move away from the external device 90. The moving platform 40 has a plug-in rail 48. The plug-in rail 48 and the moving guide rail 11 extend along a first direction F1. The charging moving base 70 is mounted on the moving platform 40 and is movable along the plug-in rail 48.

[0099] The charging base 10 provides support and guidance for the movement of the moving platform 40 and the components on the moving platform 40. The specific structure of the charging base 10 is not limited. For example, the charging base 10 can be composed of multiple side beams connected end to end, or the charging base 10 can be composed of multiple beams arranged crosswise and connected, or it can be a flat plate structure, etc.

[0100] The movable guide rail 11 can extend along a straight or curved path, requiring only one end close to the charging station of the external device 90 and one end away from the charging station of the external device 90. For example, the external device 90 can be placed on one side of the charging base 10 in the first direction F1, and the movable guide rail 11 can extend along the first direction F1, allowing the moving stage 40 to reciprocate along the movable guide rail 11 in the first direction F1, thereby driving the charging plug-in assembly 30 on the moving stage 40 to move closer to and away from the external device 90.

[0101] The movable platform 40 provides support for the movement of the charging movable base 70. The specific structures of the movable platform 40 and the charging movable base 70 are not limited. They can be composed of multiple side beams connected end-to-end, or multiple beams arranged and connected in a cross pattern, or even a flat plate structure. The structures of the movable platform 40 and the charging movable base 70 can be the same or different. The plug-in rail 48 provides guidance for the movement of the charging movable base 70 on the movable platform 40. The plug-in rail 48 can extend along a straight or curved path. The plug-in rail 48 enables the charging movable base 70 to connect the charging plug-in assembly 30 to the external device 90 for charging, or to disconnect the charging plug-in assembly 30 from the external device 90.

[0102] In the above technical solution, when the charging plug-in assembly 30 is plugged into the charging panel 91 of the external device 90 for charging, the moving stage 40 can move along the first direction F1 on the charging base 10 via the moving guide rail 11, driving the charging moving base 70 and the charging plug-in assembly 30 to quickly move to the charging station close to the external device 90. During this process, the charging plug-in assembly 30 and the charging panel 91 on the external device 90 do not engage in plugging and matching, but rather achieve rapid positioning (i.e., coarse positioning) through the movement of the moving stage 40, which saves time. The charging moving base 70 can continue to move along the first direction F1 on the moving stage 40 via the plug-in rail 48, driving the charging plug-in assembly 30 to gradually engage and match with the charging port 911 on the charging panel 91 of the external device 90. This process allows the charging plug-in assembly 30 to slowly engage with the charging port 911, performing precise plugging and unplugging operations, thereby achieving plugging in for charging or unplugging for power disconnection. The above solution enables two-level movement and positioning of the charging plug-in assembly 30 and the external device 90, which is beneficial for more precise plug-in charging operations.

[0103] 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 socket. 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.

[0104] For example, the charging plug-in assembly 30 may include an identification component that can identify the position of the plug-in module 35 relative to the charging panel 91 of the external device 90, and further identify the relative angle so that the movement module 301 can control the plug-in module 35 to adjust its posture according to the identification result of the identification component.

[0105] In the above technical solution, the moving platform 40 drives the charging moving base 70 and the charging plug-in assembly 30 to move along the moving guide rail 11 of the charging base 10 to achieve initial positioning of the charging plug-in assembly 30 and the external device 90. The charging moving base 70 drives the charging plug-in assembly 30 to move along the plug-in track 48 of the moving platform 40 to achieve further positioning of the charging plug-in assembly 30 and the external device 90. This allows the plugging and unplugging of the charging plug-in assembly 30 and the external device 90 to achieve two-stage movement, which is conducive to more precise positioning operations, reduces docking difficulty, reduces the risk of plugging and unplugging failure, improves charging efficiency, and reduces the risk of damage to the docking structure between the charging plug-in assembly 30 and the external device 90, thereby improving the reliability of the plugging and unplugging operation between the charging device 2 and the external device 90.

[0106] In some embodiments of this application, reference is made to Figure 4 and Figure 5 The moving module 301 includes a first moving module 31, which is configured to drive the charging moving base 70 to move along the insertion / removal track 48, so that the insertion / removal module 35 can be inserted / removed into the charging port 911 of the external device 90 along a first direction F1. In the above technical solution, the first moving module 31 can drive the charging moving base 70 to move on the moving platform 40 along the first direction F1, so as to realize the insertion / removal of the charging connector 351 into the charging port 911 of the external device 90.

[0107] In some embodiments of this application, reference is made to Figure 14 The first mobile module 31 includes a first driving member 311, which is retractable along a first direction F1. One end of the first driving member 311 is connected to the mobile platform 40, and the other end is connected to the charging mobile base 70.

[0108] The first driving component 311 can be a part capable of moving in the first direction F1. The first driving component 311 can be, but is not limited to, a linear module, a cylinder, a hydraulic rod, an electric actuator, etc. Optionally, the first driving component 311 can include a cylinder body and a piston rod, with the piston rod disposed in the cylinder body. In the first direction F1, the size of the charging moving seat 70 is smaller than the size of the cylinder body, thereby giving the first driving component 311 a larger extension stroke, which can increase the moving distance of the charging moving seat 70.

[0109] In the above technical solution, the first driving component 311 is a telescopic component, which can drive the charging mobile base 70 to move along the plug-in track 48 on the mobile platform 40 through telescopic means. The driving method is simple and helps to improve the reliability of operation.

[0110] In some embodiments of this application, reference is made to Figure 14The first mobile module 31 includes a first movable connector 312 and a second movable connector 313. One end of the first drive member 311 is connected to the mobile station 40 through the first movable connector 312, and the other end is connected to the charging mobile base 70 through the second movable connector 313.

[0111] The first movable connector 312 and the second movable connector 313 can be components that enable movable connection, and can be, but are not limited to, hinge seats, ball joint seats, or universal joints, etc.

[0112] In the above technical solution, the first driving component 311 can be flexibly connected to the mobile platform 40 and the charging mobile base 70 through the first movable connector 312 and the second movable connector 313, which reduces the installation requirements and helps to reduce the risk of the first driving component 311 getting stuck in the driving process due to small installation errors, so that the first driving component 311 can better drive the charging mobile base 70 to move on the mobile platform 40.

[0113] In some embodiments of this application, reference is made to Figure 14 The mobile module 301 includes a second mobile module 32, which includes a second mobile base 322 and a second driving member 321. The second mobile base 322 is located on the charging mobile base 70 and is movable along the charging position switching guide rail 80. The second driving member 321 drives the second mobile base 322 to move. The plug-in module 35 is installed on the charging mobile base 70 through the second mobile base 322.

[0114] The second driving component 321 can refer to a mechanism or component that can drive the second movable seat 322 to move along the charging position switching guide rail 80 on the charging movable seat 70. The second driving component 321 can be, but is not limited to, a linear module, cylinder, electric actuator, hydraulic rod, or other mechanism capable of outputting linear motion. The number of the charging position switching guide rail 80 and the second driving component 321 can be, but is not limited to, one, two, three, four, etc.

[0115] The second movable seat 322 can be, but is not limited to, a plate-shaped component, a planar frame structure composed of multiple beams or columns, or a frame structure composed of multiple beams that are arranged and connected at intersections, or a frame structure composed of multiple connected plates.

[0116] In the above technical solution, the plug-in module 35 can not only move along the first direction F1 under the action of the first moving module 31 to achieve positional accuracy adjustment of the plug-in module 35 in the first direction F1, but also, through the interaction of the charging position switching guide rail 80, the second moving seat 322 and the second driving member 321, the second moving module 32 can drive the plug-in module 35 to move in the second direction F2, thereby adjusting the positional accuracy of the plug-in module 35 and the charging port 911 of the external device 90 in the second direction F2. This can improve the positioning accuracy between the plug-in module 35 and the external device 90, further improve the docking success rate, reduce the risk of plugging and unplugging failure, and improve charging reliability.

[0117] In some embodiments of the application, reference is made to Figure 14 The second driving component 321 includes a rack 3211, a gear 3212 and a motor 3213. The rack 3211 is disposed on the charging movable seat 70 and extends along the second direction F2. The gear 3212 meshes with the rack 3211. The motor 3213 is connected to the gear 3212 and is mounted on the second movable seat 322.

[0118] When the charging moving base 70 needs to adjust the plug-in module 35 and the external device 90 in the second direction F2, the motor 3213 drives the gear 3212 to rotate. The gear 3212, through meshing with the rack 3211, can move along the charging position switching guide rail 80, thereby realizing the position adjustment of the plug-in module 35 in the second direction F2. The motor 3213 can be, but is not limited to, a servo motor, a stepper motor, etc. The second drive component 321 with the above structure is simple in structure, provides relatively stable drive, and reduces costs. The motor-driven method also enables higher precision control and improves positioning accuracy.

[0119] In some embodiments of this application, reference is made to Figure 14 The second movable seat 322 is provided with a third guide rail 801, which extends along the vertical direction F3 and intersects with the second direction F2 and the first direction F1. The movable module 301 includes a third movable module 33, which includes a third movable seat 332 and a third driving member 331. The third movable seat 332 is located on the second movable seat 322 and is movable along the third guide rail 801. The third driving member 331 drives the third movable seat 332 to move. The plug-in module 35 is installed on the second movable seat 322 through the third movable seat 332.

[0120] The number of third guide rails 801 can be, but is not limited to, one, two, three, four, etc. The first direction F1, the second direction F2, and the up and down direction F3 can be set at an angle to each other, and the angle between them can be non-zero degrees or 180 degrees. For example, the first direction F1, the second direction F2, and the up and down direction F3 can be perpendicular to each other.

[0121] The third movable seat 332 can be composed of multiple side beams connected end to end, or it can be composed of multiple beams arranged crosswise and connected, or it can be a flat plate structure, etc. (Reference) Figure 14 The third movable seat 332 can be a single-layer beam structure consisting of frame ends connected and internally connected intersecting beams. The third driving component 331 can be a component that can drive the third movable seat 332 to move on the second movable seat 322. The third driving component 331 can be, but is not limited to, a linear module, a cylinder, a hydraulic cylinder, or an electric actuator, etc.

[0122] In the above technical solution, through the interaction of the third guide rail 801, the third moving seat 332 and the third driving component 331, the third moving module 33 can drive the plug-in module 35 to move in the vertical F3 direction. This can adjust the positional accuracy of the plug-in module 35 and the charging port 911 of the external device 90 in the vertical direction. Under the joint action of the first moving module 31, the second moving module 32 and the third moving module 33, the plug-in module 35 can achieve positional adjustment in the first direction F1, the second direction F2 and the vertical direction F3, thereby improving the positioning accuracy between the plug-in module 35 and the external device 90, further improving the docking success rate, reducing the risk of plugging and unplugging failure, and improving charging reliability.

[0123] In the above technical solution, optionally, the third movable seat 332 can be directly slidably connected to the third guide rail 801. Optionally, refer to... Figure 14 and Figure 15 The third movable seat 332 and the third guide rail 801 can also be slidably connected by sliding blocks 802, so that the third movable seat 332 can move relative to the second movable seat 322 in the vertical direction F3. Optionally, each third guide rail 801 is provided with at least two sliding blocks 802. Optionally, the third guide rail 801 is provided with at least two along the second direction F2.

[0124] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The charging plug-in assembly 30 includes a swing module 34. The plug-in module 35 is disposed on the moving module 301 via the swing module 34. The swing module 34 drives the plug-in module 35 to swing relative to the charging moving base 70 to adjust the angle of the plug-in module 35 relative to the charging port 911.

[0125] The yaw module 34 can be a component used to drive the plug-in module 35 to adjust its angle. The adjustment angle can be one or more, for example, it can include yaw adjustment to both sides in the second direction F2 and both sides in the up and down direction F3. When the plug-in module 35 moves to the vicinity of the charging port 911 of the external device 90, there may be an angular deviation between the plug-in module 35 and the charging port 911. Directly inserting the plug-in module 35 into the charging port 911 can easily damage the charging port 911. Therefore, the yaw module 34 can further adjust the angle between the plug-in module 35 and the charging port 911, so that the plug-in module 35 can be directly connected to the charging port 911, which can reduce the risk of damage to the plug-in module 35 and the charging port 911.

[0126] In the above technical solution, the oscillation module 34 can drive the plug-in module 35 to swing relative to the moving module 301. This allows for more precise angle adjustment of the plug-in module 35, enabling accurate adjustment of the angle between the charging connector 351 of the plug-in module 35 and the charging port 911 of the external device 90. This makes the relative position angle between the plug-in module 35 and the charging port 911 more accurate, which is beneficial to further improve the success rate of docking between the plug-in module 35 and the charging port 911. This allows for more flexible adjustment of the relative posture between the plug-in module 35 and the external device 90, which is beneficial to improve the charging plug-in efficiency and accuracy, further reduce docking difficulty, reduce the risk of plug-in failure, improve charging efficiency, and also further reduce the risk of damage to the docking structure between the plug-in module 35 and the external device 90.

[0127] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The yaw module 34 includes a yaw stage 341 and multiple yaw drive units 342. The multiple yaw drive units 342 drive the yaw stage 341 to swing relative to the moving module 301. The plug-in module 35 is disposed on the yaw stage 341.

[0128] The yaw stage 341 can be a component that provides mounting support for the plug-in module 35, and can be composed of multiple side beams connected end to end, or multiple beams arranged crosswise and connected, or a flat plate structure, etc. The yaw drive unit 342 can refer to a component that provides driving force.

[0129] In the above technical solution, the oscillation stage 341 is driven to swing relative to the moving module 301 by the coordinated action of multiple oscillation drive units 342. This allows the multiple oscillation drive units 342 to perform more precise adjustment operations, and can accurately adjust the oscillation angle of the oscillation stage 341. This makes the relative position angle of the plug-in module 35 and the charging port 911 more accurate, which is conducive to further improving the docking success rate of the plug-in module 35 and the charging port 911.

[0130] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The plurality of yaw drive units 342 include a first yaw drive unit, which is disposed on at least one side of the second direction F2 of the yaw stage 341 to drive the yaw stage 341 to yaw relative to the moving module 301 to both sides of the second direction F2.

[0131] The swaying stage 341 and the moving module 301 can be provided with a swaying drive unit 342 on one side of the second direction F2, or the swaying drive unit 342 can be provided on both sides of the second direction F2. Whether the swaying drive unit 342 is provided on one side or both sides, it can drive the swaying stage 341 to swing relative to the moving module 301 on the upper and lower sides of the second direction F2.

[0132] It is understood that the yaw stage 341 and the moving module 301 can be provided with a yaw drive unit 342 on one side of the second direction F2, or the yaw drive unit 342 can be provided on both sides of the second direction F2. Regardless of whether the yaw drive unit 342 is provided on one side or both sides, it can drive the yaw stage 341 to swing relative to the moving module 301 on the upper and lower sides of the second direction F2. For example, referring to… Figure 15 The swaying stage 341 and the moving module 301 may be provided with swaying drive units 342 on both sides of the second direction F2.

[0133] In the above technical solution, the first sway drive unit can drive the sway stage 341 to sway relative to the moving module 301 to both sides in the second direction F2, thereby adjusting the angle of the charging connector 351 of the plug-in module 35 and the charging port 911 of the external device 90 in the second direction F2, which is beneficial to improve the docking success rate and reduce the risk of damage to the charging connector 351 due to docking failure.

[0134] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The plurality of yaw drive units 342 include a second yaw drive unit, which is disposed on at least one side of the yaw stage 341 in the vertical direction F3 to drive the yaw stage 341 to yaw relative to the moving module 301 in the vertical direction F3.

[0135] The yaw stage 341 and the moving module 301 can have a yaw drive unit 342 on one side of the vertical direction F3, or they can both have a yaw drive unit 342 on both sides of the vertical direction F3. Regardless of whether the yaw drive unit 342 is on one side or both sides, it can drive the yaw stage 341 to swing relative to the moving module 301 on the vertical direction F3. For example, refer to... Figure 15 The swaying stage 341 and the moving module 301 may be provided with swaying drive units 342 on the upper side of the vertical direction F3 and on both sides of the second direction F2.

[0136] In the above technical solution, the first yaw drive unit can drive the yaw platform 341 to yaw relative to the moving module 301 to both sides in the second direction F2. Based on this, the second yaw drive unit can drive the yaw platform 341 to yaw relative to the moving module 301 to both sides in the up-down direction, thereby adjusting the angle of the charging connector 351 of the plug-in module 35 and the charging port 911 of the external device 90 in the up-down direction F3. Thus, the yaw platform 341 can achieve yaw to both sides in the second direction F2 and both sides in the up-down direction F3. The yaw platform 341 has a higher degree of yaw freedom, which can further improve the docking success rate and reduce the risk of damage to the charging plug due to docking failure. In some embodiments of this application, refer to... Figure 14 and Figure 15 The yaw drive unit 342 includes a yaw drive member 3421 and a first universal joint 3422. The yaw drive member 3421 is disposed on the moving module 301 and is movable along the first direction F1. The moving end of the yaw drive member 3421 is connected to the yaw table 341 through the first universal joint 3422.

[0137] The yaw drive component 3421 can be, but is not limited to, a cylinder, a hydraulic cylinder, an electric actuator, etc. The first universal joint 3422 can be, but is not limited to, a ball joint, a universal joint, etc.

[0138] In the above technical solution, the yaw drive component 3421 can extend or shorten along the first direction F1, thereby causing one side of the yaw stage 341 to yaw relative to the moving module 301. The yaw drive component 3421 and the yaw stage 341 can be movably connected through the first universal joint 3422. Thus, when one or more yaw drive components 3421 move, the remaining yaw drive components 3421 perform adaptive movements under the action of the corresponding first universal joint 3422. In this way, multiple yaw drive components 342 can cooperate to adjust the yaw angle.

[0139] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The yaw module 34 includes a support column 343 and a second universal joint 344. The support column 343 extends along the first direction F1 and is fixed to the moving module 301, and is connected to the yaw table 341 through the second universal joint 344. Multiple yaw drive components 3421 are arranged circumferentially around the support column 343.

[0140] The support column 343 can be a solid column or a hollow column, or it can be a frame structure composed of multiple side frames connected end to end, or a frame structure composed of multiple side frames and intersecting beams, etc. The second universal joint 344 can be, but is not limited to, a ball joint or universal joint, etc.

[0141] In the above technical solution, multiple yaw drive units 342 can drive the yaw table 341 to yaw around the support column 343 through the second universal joint 344. That is, the support column 343 can provide support for the yaw motion of the yaw table 341, which is beneficial to improving the stability and reliability of the yaw table 341 in the process of yaw adjustment.

[0142] In some embodiments of this application, the yaw drive 3421 is hingedly connected to the moving module 301. For example, see reference... Figure 14 and Figure 15 The yaw drive 3421 can be connected to the third movable seat 332 of the moving module 301 via the hinge component 803. In the above technical solution, the yaw drive 3421 can be movably connected to the moving module 301, thereby reducing the risk of jamming during the movement adjustment process of the yaw drive 3421 by swinging relative to the moving module 301, which can improve the reliability of the yaw drive 3421 during the yaw angle adjustment process.

[0143] In some embodiments of this application, reference is made to Figure 4 , Figure 5 and Figure 14 The charging plug-in assembly 30 includes a buffer structure 36, which is located between the plug-in module 35 and the yaw module 34. The buffer structure 36 is configured to be deformable in cooperation with the plug-in module 35 and the external device 90 to drive the plug-in module 35 to move.

[0144] The buffer structure 36 is an elastically deformable structure. When the plug-in module 35 is engaged with the charging port 911, the buffer structure 36 can deform. The buffer structure 36 can be a disc spring, a wave spring, or a polyurethane block, etc. Through the deformation of the buffer structure 36, the plug-in module 35 is moved relative to the moving module 301, thereby making the plug-in module 35 a floating structural component.

[0145] When the plug-in module 35 engages with the charging port 911, the plug-in module 35 moves towards the external device 90 under the drive of the moving module 301. As the plug-in module 35 moves, the length of the portion of the plug-in module 35 extending into the charging port 911 gradually increases until the length of the portion of the plug-in module 35 extending into the charging port 911 is consistent with the depth inside the charging port 911. When the moving module 301 drives the plug-in module 35 to continue moving, the buffer structure 36 can deform, giving the plug-in module 35 floating space. This allows the plug-in module 35 to make flexible contact with the charging port 911, thereby preventing the plug-in module 35 from continuing to extend into the charging port 911 and causing collision damage between the plug-in module 35 and the charging port 911, reducing the failure rate and increasing the service life. At the same time, through the deformation of the buffer structure 36, the plug-in module 35 can maintain a predetermined pressure, thereby improving the reliability of the engagement between the plug-in module 35 and the charging port 911, and thus enabling stable charging of the external device 90.

[0146] It should be noted that when the buffer structure 36 deforms, the plug-in module 35 can float along the extension direction of the charging connector 351 (i.e. the plugging and unplugging direction of the charging connector 351). In addition, the plug-in module 35 can also generate a slight oscillation to ensure that the plug-in module 35 is coaxial with the charging port 911.

[0147] During the insertion of the plug-in module 35, the buffer structure 36 deforms to store energy, and releases the energy of the buffer structure 36 when it is pulled out. Under the action of the buffer structure 36, the force exerted by the moving module 301 on the plug-in module 35 can also be reduced, thereby reducing the system energy consumption.

[0148] In the above technical solution, by setting the buffer structure 36, the plug-in module 35 can have a floating space, so that the plug-in module 35 can be flexibly plugged and unplugged with the external device 90, which to a certain extent avoids wear caused by rigid collision between the plug-in module 35 and the charging port 911, and improves the service life of the assembly; at the same time, it is beneficial to maintain the plug-in module 35 under a predetermined pressure to cooperate with the charging port 911, thereby improving the charging reliability.

[0149] In some embodiments of this application, reference is made to Figure 14 One of the plug-in module 35 and the yaw module 34 has a limiting post 353, and the other of the plug-in module 35 and the yaw platform 341 has a limiting hole 345. The limiting post 353 passes through the limiting hole 345 and can slide with the limiting hole 345. The buffer structure 36 is a spring sleeved on the outer periphery of the limiting post 353, and the buffer structure 36 abuts against the yaw platform 341.

[0150] The plug-in module 35 has multiple limiting posts 353 on one side, which are spaced apart circumferentially along the plug-in module 35. The tilting platform 341 has limiting holes 345 through which the limiting posts 353 pass. Through the sliding engagement of the limiting posts 353 and the limiting holes 345, the movement direction of the plug-in module 35 can be limited, preventing the plug-in module 35 from shaking significantly when the buffer structure 36 deforms, thus affecting the engagement between the plug-in module 35 and the charging port 911. Of course, the limiting posts 353 can also be provided on the tilting platform 341, and the limiting holes 345 can be provided on the connector panel 354.

[0151] The buffer structure 36 is a spring, which can be a square spring or a round spring. Each limiting post 353 is fitted with a spring.

[0152] In the above technical solution, by setting the sliding fit limiting post 353 and limiting hole 345, the movement of the plug-in module 35 can be guided, thereby improving the reliability of the fit between the plug-in module 35 and the charging port 911 and reducing the probability of damage caused by the shaking of the plug-in module 35 and the hard plugging and unplugging of the charging port 911. By sleeved the buffer structure 36 on the limiting post 353, the deformation direction of the spring can be guided, reducing the probability of the buffer structure 36 shaking or shifting in other directions or getting stuck, thus ensuring the effectiveness of the spring's deformation energy storage function and improving the service life of the spring.

[0153] In some embodiments, refer to Figure 14 and Figure 15 The outer periphery of the limiting post 353 is provided with a limiting protrusion 3531, and the other end of the buffer structure 36 abuts against the limiting protrusion 3531. That is to say, the two ends of the buffer structure 36 abut against the limiting protrusion 3531 and the tilting platform 341 respectively. This can appropriately increase the distance between the plug-in module 35 and the tilting platform 341, so as to facilitate the installation of components on the plug-in module 35. At the same time, there is no need to increase the size of the buffer structure 36, thereby avoiding problems such as compression instability caused by the buffer structure 36 being too long.

[0154] In some embodiments of this application, reference is made to Figure 14 and Figure 15 The plug-in module 35 includes a connector panel 354, a positioning pin 352, and a charging connector 351. The positioning pin 352 and the limiting pin 353 are connected to opposite sides of the connector panel 354 and are located on the same side of the connector panel 354 as the charging connector 351. The positioning pin 352 is adapted to be plugged into the positioning hole 912 of the external device 90, and the charging connector 351 is adapted to be connected to the charging port 911 of the external device 90 to charge the external device 90.

[0155] Reference Figure 1The external device 90 is equipped with a charging panel 91, which has multiple positioning holes 912. The connector panel 354 has multiple positioning pins 352. The positioning pins 352 are inserted into the positioning holes 912 to position the charging panel 91 and the plug-in module 35. This enables synchronous positioning of the charging port 911, ensuring that the charging connector 351 and the charging port 911 are in the same position before plugging the charging connector 351 into the charging port 911. This avoids wear on the charging connector 351 and improves the service life of the charging plug-in assembly 30.

[0156] In the above technical solution, when the external device 90 moves toward the charging plug assembly 30, the positioning pin 352 first inserts into the corresponding positioning hole 912 to converge the positional deviation of the external device 90 relative to the charging plug assembly 30, so that the subsequent charging connector 351 completes the insertion in the predetermined alignment state, so as to achieve zero lateral force docking, which can further improve the positioning accuracy of docking, reduce the probability of damage to the charging connector 351, improve the reliability of charging and the service life of the charging plug assembly 30.

[0157] In some embodiments of this application, reference is made to Figure 15 One end of the positioning pin 352 has a positioning connector 3521. The cross-sectional dimensions of the positioning connector 3521 gradually increase along the direction close to the other end of the positioning pin 352. The height of the positioning pin 352 protruding from the connector panel 354 is greater than the height of the charging connector 351 protruding from the connector panel 354.

[0158] The positioning connector 3521 at the end of the positioning pin 352 forms a frustum or cone structure. The positioning connector 3521 has a large tolerance range. During the process of the external device 90 and the charging plug-in assembly 30 moving towards each other, the positioning connector 3521 contacts the positioning hole 912 first to converge the initial position error of the external device 90 relative to the plug-in module 35, so as to achieve accurate positioning in the last segment before the insertion stroke, thereby ensuring that the subsequent charging connector 351 cooperates with the charging socket 911 in a state of zero lateral force.

[0159] In some specific examples, when the identification component on the charging plug-in assembly 30 or other means aligns the plug-in module 35 with the charging panel 91 of the external device 90, there may be a certain deviation between the center of the positioning pin 352 and the center of the positioning hole 912. By appropriately limiting the size and tilt angle of the positioning connector 3521, a portion of the positioning connector 3521 can extend into the positioning hole 912 even with the aforementioned deviation. As the moving module 301 drives the plug-in module 35 to continue moving forward along the first direction F1, the end face of the positioning hole 912 and the positioning pin 3522... With the cooperation of the positioning connector 3521, the inclined surface of the positioning connector 3521 can slide relative to the end face of the positioning hole 912, thereby driving the positioning pin 352, the connector panel 354 and the charging connector 351 to move along the second direction F2 and the up and down direction F3 until the outer periphery of the positioning connector 3521 is completely inserted into the positioning hole 912. At this time, the center of the positioning pin 352 coincides with the center of the positioning hole 912, thereby ensuring that the charging connector 351 corresponds to the charging port 911. The charging connector 351 can be inserted into the charging port 911 and is not easily damaged by collision.

[0160] Reference Figure 14 On the surface of the protruding connector panel 354, the extension direction of the positioning pin 352 is the same as the extension direction of the charging connector 351, such as the first direction F1. The positioning pin 352 is longer than the charging connector 351. Therefore, the insertion action of the plug-in module 35 and the external device 90 includes a two-stage stroke, that is, the positioning pin 352 and the positioning hole 912 are positioned first, and then the charging connector 351 and the charging port 911 are powered.

[0161] Therefore, after the positioning pin 352 and the positioning hole 912 are fully aligned, the charging connector 351 and the charging socket 911 are fully aligned, resulting in a high success rate of insertion and removal. At the same time, it can protect the charging connector 351, reduce the risk of scratches between the charging connector 351 and the charging socket 911, and improve the reliability and service life of the charging connector 351.

[0162] In the above technical solution, by setting a positioning connector 3521 at the end of the positioning pin 352, it is beneficial to absorb the centering error during insertion and removal, reduce the shearing force between the positioning hole 912 and the positioning pin 352, reduce wear and insertion thrust, and improve service life; at the same time, it can improve the matching accuracy between the positioning pin 352 and the positioning hole 912, thereby improving the matching accuracy between the charging connector 351 and the charging socket 911, improving the insertion and removal success rate, and improving the reliability of charging.

[0163] In some embodiments of this application, reference is made to Figure 4 The moving platform 40 is provided with support rollers 42, which are rotatably supported on the upper surface of the moving guide rail 11.

[0164] The support rollers 42 can be made of corrosion-resistant and high-strength materials such as nylon and stainless steel, which can stably support the moving platform 40 and the charging plug assembly 30, and are not easily corroded or damaged by contact with rainwater, mud, etc.

[0165] There can be multiple support rollers 42, and each moving guide rail 11 can cooperate with multiple support rollers 42. The multiple support rollers 42 corresponding to the same moving guide rail 11 are spaced apart along the extension direction of the moving guide rail 11.

[0166] In the above technical solution, by cooperating with the support roller 42 and the moving guide rail 11, rolling friction can be formed between the moving table 40 and the moving guide rail 11, which effectively reduces the resistance of the moving table 40, thereby improving the accuracy of the moving stroke control of the moving table 40 and improving the moving efficiency.

[0167] In some embodiments of this application, the base assembly 3 is provided with a wire hole, and the charging device 2 includes a cable 61. Part of the cable 61 is located on the lower side of the base assembly 3, and the other part passes through the wire hole and is electrically connected to the charging plug assembly 30 to supply power to the charging plug assembly 30.

[0168] Reference Figure 15 The base assembly 3 may include a charging base 10 and a moving platform 40. The cable passage may include a second cable passage 10a and a third cable passage 40a. The charging base 10 is provided with a second cable passage 10a, and the moving platform 40 is provided with a third cable passage 40a. Part of the cable 61 is located on the lower side of the charging base 10, and the other part passes through the second cable passage 10a and the third cable passage 40a and is electrically connected to the charging plug assembly 30 to supply power to the charging plug assembly 30.

[0169] The charging base 10 can be a plate-shaped component, and the second wire-passing hole 10a can be a hole structure opened in the plate-shaped component; the charging base 10 can also be a base structure composed of a frame connected end to end and multiple beams connected at intersection, and the second wire-passing hole 10a can be a hollow structure formed between the frame and the beams. Similarly, the moving platform 40 can be a plate-shaped component, and the third wire-passing hole 40a can be a hole structure opened in the plate-shaped component; the moving platform 40 can also be a base structure composed of a frame connected end to end and multiple beams connected at intersection, and the third wire-passing hole 40a can be a hollow structure formed between the frame and the beams.

[0170] Optionally, the second wire hole 10a can be an elongated hole extending along the first direction F1, thereby enabling the cable 61 to move along the moving table 40 as it moves along the moving guide rail 11.

[0171] In the above technical solution, the cable 61 can pass through the cable hole to the base assembly 3. This helps to reduce the length of the cable 61, save materials, and also improves the overall structural compactness of the charging device 2, saving space. The above solution also protects the cable 61, reducing the risk of the cable 61 being located outside the base assembly 3, thereby reducing the risk of the cable 61 being scratched or damaged during long-term use and improving the reliability of the cable 61.

[0172] In some embodiments of this application, referring to the figures, the charging device 2 includes a support assembly 62, which is disposed on the lower side of the base assembly 3 and includes a support member 621 and a support wheel 622. A cable 61 is mounted on the support member 621, and the support wheel 622 is disposed on the support member 621 and is used to support walking on the walking surface. The support wheel 622 is configured to be able to walk at least in the second direction F2.

[0173] There can be one, two, three, four or more support components 62 to meet the support requirements of cables 61 of different sizes. For example, there can be four support components 62. In each support component 62, there can be one, two or more support members 621 and support wheels 622. For example, in each support component 62, there is one support member 621 and two support wheels 622.

[0174] In the above technical solution, by supporting the cable 61 with the support component 62, the resistance encountered by the cable 61 and the charging plug assembly 30 during movement can be reduced, and the cable 61 does not need to be dragged by manpower, saving manpower. Specifically, by using the support component 621 to stably install the cable 61, the possibility of the cable 61 slipping off the support component 62 can be reduced, and the support stability of the support component 62 for the cable 61 can be improved.

[0175] In some embodiments of this application, the support wheel 622 is a swivel wheel. In this technical solution, the support wheel 622 is a swivel wheel, which can move in multiple directions and can flexibly adapt to the movement direction of the cable 61, thereby improving the flexibility of supporting the cable 61.

[0176] In some embodiments of this application, reference is made to Figure 16 The charging device 2 also includes a first driving component 46, which includes a fourth driving member 461, a first fixing member 462 and a first moving member 463. The first fixing member 462 is connected to the charging base 10, and the first moving member 463 is connected to the moving platform 40. The fourth driving member 461 is configured to drive the first moving member 463 to move relative to the first fixing member 462, so as to drive the moving platform 40 to move along the moving guide rail 11.

[0177] The first fixing member 462 is a component that does not move relative to the charging base 10 in the extending direction of the moving guide rail 11, but the first fixing member 462 can rotate, for example, the first fixing member 462 can be a rotatable lead screw, and the rotation axis of the lead screw is parallel to the extending direction of the moving guide rail 11. This application does not limit this.

[0178] The first moving part 463 is a component that can move relative to the charging base 10 in the extension direction of the moving guide rail 11. Of course, the first moving part 463 may not have other forms of movement during the movement process, or it may have other forms of movement, such as rotation with the rotation axis parallel to the extension direction of the moving guide rail 11. This application does not limit this.

[0179] The fourth drive component 461 can be, but is not limited to, an electric cylinder, a servo motor, etc.

[0180] The fourth driving member 461 can be connected to the first fixed member 462. By driving the first fixed member 462 to move, the first moving member 463 moves relative to the first fixed member 462. For example, the first fixed member 462 can be a lead screw. The fourth driving member 461 is connected to the lead screw and drives the lead screw to rotate. The first moving member 463 is connected to the lead screw by a thread. During the rotation of the lead screw, the first moving member 463 moves along the extension direction of the moving guide rail 11. Alternatively, the first driving member can be connected to the first moving member 463. By driving the first moving member 463 to move, the first moving member 463 moves relative to the first fixed member 462. For example, the first moving member includes a sleeve and a nut. The nut is located inside the sleeve. The nut is fixed relative to the sleeve and rotatable relative to the sleeve in the extension direction of the moving guide rail 11. The nut has an internal thread and engages with the external thread of the first fixed member. The first driving member drives the nut to rotate, so that the nut moves along the first fixed member 462 and drives the sleeve to move along the first fixed member 462, thereby driving the moving table 40 to move along the extension direction of the moving guide rail 11.

[0181] Of course, the specific structure of the first drive component 46 is not limited to this, as long as it can automatically drive the moving stage 40 to move along the moving guide rail 11.

[0182] In the above technical solution, by setting the first driving component 46, the automatic driving of the mobile platform 40 and the external device 90 can be positioned, thereby improving the automation level of the charging device 2, reducing labor costs, and improving charging efficiency.

[0183] This application also provides a charging system 1, including a seating frame 20 and a charging device 2 as described in any of the preceding embodiments. The seating frame 20 is connected to the charging base 10 and is used to place an external device 90.

[0184] The mounting bracket 20 provides support for the external device 90. The mounting bracket 20 can be partially pre-buried underground to fix it in place. After the external device 90 is placed on the mounting bracket 20, the external device 90 can be aligned with the charging plug assembly 30 along the first direction F1. The mounting bracket 20 can position the external device 90, reducing the probability of the external device 90 tilting or swaying, while protecting the external device 90 from physical damage to the ground and extending its service life. The mounting bracket 20 can also improve the contact alignment accuracy of the charging connector 351 and reduce the probability of poor contact. In addition, a monitoring module can be integrated on the mounting bracket 20 for automatic power on / off.

[0185] Since the charging device 2 according to the embodiments of this application has the above-mentioned beneficial technical effects, the charging system 1 according to the embodiments of this application can precisely position the external device 90 through the seating frame 20, fix the position of the external device 90, and then drive the charging plug assembly 30 to move along the second direction F2 to the charging position through the charging position switching guide rail 80, so that the charging plug assembly 30 and the multiple sets of charging ports 911 of the external device 90 can be accurately matched. Then, the charging moving seat 70 drives the charging plug assembly 30 to move along the first direction F1, so that the charging plug assembly 30 and the charging port 911 of the external device 90 can be plugged in for charging. After the charging is completed, it is switched to the next charging position by the charging position switching guide rail 80, so that the charging plug assembly 30 and the other set of charging ports 911 of the external device 90 can be matched and plugged in for charging. Thus, the charging system 1 can perform mechanical docking charging of the multiple sets of charging ports 911 of the external device 90, which can improve the charging efficiency, replace manual docking and reduce the docking failure rate, and also help improve the charging reliability.

[0186] In some related technologies, tower cranes are typically used to hoist external equipment to the charging equipment. However, this requires repeated adjustments to the position of the external equipment by the tower crane to align it with the charging equipment before lowering it. This results in excessive hoisting time, long on-site alignment time (aligning the external equipment with the charging equipment), and low charging efficiency for the external equipment. This application, however, uses a mounting frame 20 to place the external equipment 90, enabling rapid hoisting of the external equipment 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 external equipment 90 at the battery swapping station. It also ensures high charging efficiency for the external equipment 90 and eliminates the need for additional facilities at the battery swapping station to house it, reducing the construction cycle and allowing for rapid operation.

[0187] In some embodiments, refer to Figures 1-4The seating frame 20 is provided with a guide component 21, which has a guide slope extending from top to bottom and inward. The guide slope guides the external device 90 during the process of placing the external device 90 on the seating frame 20, so that the external device 90 is opposite to the charging device 2 along the first direction F1 after being placed on the seating frame 20. This helps to reduce the difficulty of placing the external device 90 and improve the placement accuracy of the external device 90.

[0188] In some embodiments where the charging base 10 is connected to the positioning element 22, the guide component 21 on the seat frame 20 near the end of the charging base 10 can be used as the positioning element 22. On the one hand, it plays a positioning role, and on the other hand, it plays a avoidance role, preventing the guide component 21 from interfering with the movement of the moving platform 40.

[0189] In some embodiments of this application, the charging system 1 is used to charge a box-type power supply, which is a replaceable power source for electric ships. In this technical solution, the charging system 1 can be applied to scenarios involving charging electric ships. The external device 90 can be a replaceable power source for the electric ship; that is, the external device 90 can be a box-type power supply. The box-type power supply can be detached from the electric ship and placed on the mounting frame 20. The charging device 2 enables plug-and-play charging of the box-type power supply, which can improve the success rate of docking with the box-type power supply and increase charging efficiency.

[0190] like Figures 1-11 As shown, the charging system 1 according to the first specific embodiment of this application 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 a box-type power supply. The box-type power supply has two charging panels 91, which are connected to two charging and discharging circuits inside the box-type power supply. Each charging panel 91 is provided with a set of charging ports 911, and the number of charging ports 911 in each set is multiple. The charging device 2 includes a charging base 10, a moving platform 40, a charging moving base 70, a charging plug-in assembly 30, and a cable 61.

[0191] The charging base 10 includes a charging frame and two movable guide rails 11. The movable guide rails 11 extend along a first direction F1, and the two movable guide rails 11 are spaced apart along a second direction F2 and placed on the charging frame. The first direction F1, the second direction F2, and the vertical direction F3 are perpendicular to each other, with the vertical direction F3 being the vertical direction.

[0192] The moving platform 40 is movably mounted on the moving guide rail 11 of the charging base 10 along the first direction F1 via support rollers 42. The first drive component 46 is an electric cylinder. One end of the electric cylinder is hinged to the lower end of the moving platform 40 via a pin, and the other end of the electric cylinder is hinged to the charging base 10. The electric cylinder extends and retracts to drive the entire moving platform 40 to perform linear movement on the moving guide rail 11.

[0193] The charging mobile base 70 is movably mounted on the plug-in track 48 of the mobile platform 40 via a slider.

[0194] The charging plug-in assembly 30 is movably mounted on the charging mobile base 70 in the second direction F2 via the charging position switching guide 80, and is used to connect to the box-type power supply for charging the box-type power supply through the charging plug-in assembly 30. Cable 61 is electrically connected to the charging plug-in assembly 30 to supply power to the charging plug-in assembly 30. Cable 61 is supported by casters on the support assembly 62 for movement on the walking surface, accommodating the movement of cable 61 during plugging / unplugging and attitude adjustment.

[0195] 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 first moving module 31 is an electric cylinder. One end of the electric cylinder is hinged to the lower end of the charging moving base 70 via a pin, and the other end of the electric cylinder is hinged to the moving platform 40 via a pin. The extension and retraction of the electric cylinder drives the entire charging moving base 70 to move linearly on the plugging and plugging track 48. The second moving module 32 includes a second moving base 322 and a second driving member 321. The second moving base 322 is a moving frame. The bottom of the moving frame is slidably connected to the charging position switching guide rail 80 on the charging moving base 70 along the second direction F2 via a slider. The second driving member 321 includes a rack 3211, a gear 3212 and a motor 3213. The rack 3211 is fixed on the charging moving base 70 and extends along the second direction F2. The gear 3212 and the rack 3211 mesh and are connected to the motor shaft of the motor 3213. The motor 3213 is fixed to the bottom of the moving frame. The motor 3213 drives the gear 3212 to rotate, which can drive the moving frame to move along the second direction F2 on the charging moving base 70. The third moving module 33 includes a third moving base 332 and a third driving component 331. The third moving base 332 is a hollow moving plate and is slidably mounted on the guide rail of the moving frame in the vertical direction F3 via a slider. The third driving component 331 is an electric cylinder that extends and retracts in the vertical direction. One end of the electric cylinder is hinged to the upper part of the moving plate via a pin, and the other end of the electric cylinder is hinged to the lower part of the moving frame via a pin, so as to drive the moving plate to move relative to the moving frame 2 in the vertical direction F3.

[0196] The yaw module 34 includes a yaw platform 341, three yaw drive units 342, a support column 343, and a second universal joint 344. The yaw platform 341 and the moving plate are spaced apart along the first direction F1 and connected by the three yaw drive units 342. The yaw platform 341 and the moving plate have yaw drive units 342 on their upper sides in the vertical direction F3. The yaw platform 341 and the moving plate each have a yaw drive unit 342 on their respective sides in the second direction F2. The plug-in module 35 is located on the yaw platform 341. The yaw drive unit 342 includes a yaw drive component 3421 and a first universal joint 3422. The yaw drive component 3421 is an electric cylinder and is telescopic along the first direction F1. One end of the electric cylinder is connected to the yaw platform 341 through the first universal joint 3422, and the other end is hinged to the moving plate through a pin. The support column 343 extends along the first direction F1 and is fixed to the movable plate, and is connected to the oscillating platform 341 through the second universal joint 344. Three oscillating drive components 3421 are arranged around the support column 343 in a circumferential manner.

[0197] The plug-in module 35 includes a connector panel 354, a positioning pin 352, and a charging connector 351. The positioning pin 352 and the limiting pin 353 are connected to opposite sides of the connector panel 354 and are located on the same side of the connector panel 354 as the charging connector 351. The positioning pin 352 is adapted to be plugged into the box-type power supply, and the charging connector 351 is adapted to be connected to the charging port 911 of the box-type power supply to charge the box-type power supply 90.

[0198] When charging the box-type power supply is required, it can be placed on the seating frame 20 using a hoisting device and guided by the guide assembly 21. The charging plug-in assembly 30 first moves along the charging position switching guide rail 80 in the second direction F2 to the charging position, directly facing one of the charging panels 91 of the box-type power supply. Then, the moving stage 40 moves along the moving guide rail 11 of the charging base 10 towards the box-type power supply in the first direction F1, bringing the charging moving base 70 and the charging plug-in assembly 30 closer to the box-type power supply until the detector comes into contact with the box-type power supply, completing the initial positioning. At this point, the moving stage 40 stops moving. The charging plug-in assembly 30 is relatively close to the box-type power supply, resulting in higher accuracy in relative position and relative angle detection. Therefore, it can be used with the aid of the recognition component through point laser ranging and D vision. The relative position and angle between the plug-in module 35 and the charging panel 91 are identified by means of feature hole positioning, etc. According to the identification results, 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. The first moving module 31 drives the charging moving base 70 to move along the first direction F1 to slowly adjust the precise position of the plug-in module 35 and the charging panel 91 in the first direction F1. Then, the second moving module 32 and the third moving module 33 achieve precise adjustment in the second direction F2 and the up and down direction F3. The relative angle is adjusted by the yaw module 34 so that the plug-in module 35 is accurately aligned with the corresponding charging panel 91 through one of the charging connectors 351 and plugged in for charging.

[0199] After the corresponding circuit of the charging panel 91 is fully charged, the first moving module 31 drives the charging moving base 70 to move away from the box power supply along the first direction F1, so that the plug-in module 35 is separated from the charging panel 91. The second moving module 32 drives the plug-in module 35 to move along the second direction F2 to another charging position under the action of the charging position switching guide rail 80, so that it is opposite to the corresponding charging panel 91. By readjusting the relative position and relative angle, the first moving module 31 moves closer to the box power supply along the first direction F1 so that the plug-in module 35 is plugged into the charging panel 91 for charging. This realizes the second channel plug-in charging of the plug-in module 35 and the box power supply.

[0200] 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 along the first direction F1. At this time, the box-type power supply can be moved by hoisting.

[0201] In the above embodiments, the plug-in module 35 can switch between two charging positions under the action of the charging position switching guide rail 80, thereby enabling the charging device 2 to plug in and charge the two charging panels 91 of the dual-channel box power supply. The moving stage 40 moves along the charging base 10 to achieve initial engagement and positioning of the charging moving seat 70 and the charging plug-in assembly 30 relative to the box power supply, providing conditions for improving the accuracy of subsequent relative position and angle recognition. The charging moving seat 70 can then drive the plug-in module 35 to plug in and charge or unplug it from the charging panel 91 to disconnect power. The charging plug-in assembly 30 can actively adjust its charging posture with multiple degrees of freedom, enabling automatic plug-in and unplugging charging in a dual-circuit manner. The charging connector 351 and the socket of the charging panel 91 are aligned at a high height, resulting in a high success rate of plugging and unplugging. The guide post of the plug-in module 35 and the pin of the socket experience less wear, leading to a longer lifespan and more stable and reliable performance.

[0202] The charging system 1 of this application features a modular design. The charging station of the mounting frame 20 is one module, and the charging device 2 is 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 identification component uses laser ranging to measure the distance and angle of the charging panel 91 area of ​​the box-type power supply. The charging device 2 aligns the plug-in module 35 with the charging panel 91 and then uses 3D 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 socket and charging connector 351 within 0.3mm on each side, resulting in high plug-in accuracy and a high success rate.
