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 the 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, in related technologies, the docking operation between the charging equipment and the power supply is difficult and lacks precision, making docking prone to failure, resulting in low charging efficiency and potential damage to the docking structure. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a charging device that reduces the difficulty of charging connection and the risk of failure.

[0004] A charging device according to an embodiment of the present invention includes: a charging plug-in assembly, the charging plug-in assembly including a movable module and a plug-in module, the plug-in module being provided with a charging connector, the plug-in module being disposed on the movable module, the movable module being used to drive the charging connector on the plug-in module to cooperate with a charging port on an external device to charge the external device; and a movable platform, the charging plug-in assembly being mounted on the movable platform, the external device having a seating position, and the movable platform being movable relative to the seating position to move closer to and further away from the external device.

[0005] According to the charging device of this utility model embodiment, the charging plug assembly is moved relative to the seating position of the external device by the moving platform to achieve the initial positioning of the charging plug assembly and the external device. The charging connector of the plug module is moved by the movable module of the charging plug assembly to achieve the further positioning of the charging connector and the charging port of the external device. This enables the charging connector and the charging port to achieve more precise positioning and matching, reduces the difficulty of docking, reduces the risk of plugging and unplugging failure, improves charging efficiency, and reduces the risk of damage to the docking structure of the charging connector and the charging port.

[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 mobile platform has a first position and a second position arranged along a first direction, the first position being farther away from the seating position of the external device relative to the second position, and the mobile platform being located at the first position when there is no external device at the seating position.

[0007] In the above technical solution, the distance between the mobile station in the first position and the sitting position is greater. When there is no external device in the sitting position, the mobile station is in the first position, which makes the space near the sitting position larger. When placing external devices in the sitting position, it is not easy for them to interfere with or collide with the mobile station, thus improving the convenience of sitting.

[0008] According to some embodiments of the present invention, the charging device further includes a second position positioning structure, which is triggered to operate when the mobile platform is in the second position.

[0009] In the above technical solution, by setting a second positioning structure, the second positioning structure can detect the initial positioning state of the mobile station and the external device, so that it can be triggered and take corresponding measures when the initial positioning is completed, such as controlling the mobile station to stop moving when the initial positioning is completed.

[0010] According to some embodiments of the present invention, the external device is a box-type power supply, the mobile platform is located at the end of the box-type power supply along the first direction, the mobile platform moves closer to and further away from the box-type power supply along the first direction, the first direction being the length direction of the box-type power supply.

[0011] In the above technical solution, the moving platform moves along the length of the box-type power supply, enabling the charging plug-in assembly to move along the length of the box-type power supply. The moving path of the moving platform is more regular and better matched to the box-type structure of the box-type power supply, which is more conducive to improving the initial positioning effect of the charging plug-in assembly relative to the box-type power supply.

[0012] According to some embodiments of the present invention, the charging device further includes a charging base, the charging base having a movable guide rail, the movable platform being mounted on the charging base and movable along the movable guide rail, and the charging base being immovable relative to the seating position.

[0013] In the above technical solution, the charging base and the moving guide rail provide support and guidance for the movement of the mobile platform and the components on it, making the movement of the mobile platform more stable, which is beneficial to improving positioning accuracy and reducing the likelihood of jamming during movement. Furthermore, since the charging base is immovable relative to the seating position, the distance the mobile platform moves along the moving guide rail is the same as the distance it moves relative to the seating position, making the movement control of the mobile platform simpler and the positioning accuracy higher.

[0014] According to some embodiments of the present invention, a positioning part is provided at one end of the mobile platform facing the external device, and a positioning component is connected to the charging base. When the mobile platform is in the second position, the positioning component and the positioning part cooperate with each other.

[0015] In the above technical solution, the positioning component and positioning part can play a positioning role in the movement of the mobile station, so that when the mobile station moves to the second position, the position relative to the sitting position and the external device located at the sitting position is more accurate.

[0016] According to some embodiments of the present invention, the movable platform is provided with supporting rollers, which are rotatably supported on the upper surface of the movable guide rail.

[0017] In the above technical solution, by cooperating with the support roller and the moving guide rail, rolling friction can be formed between the moving stage and the moving guide rail, which can effectively reduce the resistance of the moving stage, thereby improving the accuracy of the moving stage stroke control and improving the moving efficiency.

[0018] According to some embodiments of the present invention, the movable guide rails are two and spaced apart along the axial direction of the supporting rollers. The outer peripheral surface of the supporting rollers includes a conical surface, which contacts and engages with the upper surface of the movable guide rails. In the two movable guide rails corresponding to the supporting rollers, the small ends of the conical surfaces are close to each other and the large ends are far apart.

[0019] In the above technical solution, the cooperation between the mobile platform and two moving guide rails makes the support of the charging base on the mobile platform more stable, and the mobile platform is less likely to tip over. By having the conical surface of the support rollers contact and cooperate with the moving guide rails, the support rollers can be subjected to a force close to the center of the mobile platform in the axial direction of the support rollers during rolling. Thus, the support rollers on the two moving guide rails cooperate to level the mobile platform, making it less likely to tilt or tip over.

[0020] According to some embodiments of the present invention, the outer peripheral surface of the support roller is provided with a limiting flange, and in the axial direction of the support roller, the limiting flange is located on the side of the moving guide rail away from the center of the moving platform.

[0021] In the above technical solution, when the moving stage deviates in the axial direction of the supporting roller, the limiting flange can cooperate with the side of the moving guide rail to limit the movement, preventing the moving stage from deviating or the deviation size from being too large and affecting the positioning of the charging plug-in assembly and the external device. This helps to improve the positioning accuracy and reduce the risk of the moving stage derailing.

[0022] According to some embodiments of the present invention, the movable platform is provided with guide rollers, the axis of the guide rollers is parallel to the vertical direction, and the guide rollers are in rolling cooperation with the side of the movable guide rail away from the center of the movable platform.

[0023] In the above technical solution, by cooperating with the side of the guide roller opposite to the center of the moving platform, the guide roller and the moving platform can interfere in the direction perpendicular to the moving direction, thereby restricting the moving platform from moving in the direction perpendicular to the moving direction, so that the moving platform can move stably along the moving platform and improve the initial positioning effect of the charging plug-in assembly and the external device.

[0024] According to some embodiments of the present invention, the moving platform is provided with a scraper, and the scraper is in clearance fit with the surface of the moving guide rail.

[0025] In the above technical solution, by setting a scraper that can move with the moving table relative to the moving guide rail, the scraper can scrape off mud and other attachments on the surface of the moving guide rail, thereby improving the stability of the support rollers and guide rollers rolling along the moving guide rail.

[0026] According to some embodiments of the present invention, the scraper is provided with a downward-opening scraping groove, the scraping groove extends through the scraper along the extending direction of the moving guide rail, and at least the upper part of the moving guide rail is located within the scraping groove.

[0027] In the above technical solution, the scraper groove can scrape off the attachments on the upper surface and sides of the moving guide rail, so that the support roller can stably cooperate with the upper surface of the moving guide rail, and the guide roller can stably cooperate with the side surface of the moving guide rail. The scraper groove has a more comprehensive cleaning effect on the attachments on the moving guide rail.

[0028] According to some embodiments of the present invention, the mobile platform includes multiple crossbeams, multiple longitudinal beams, and a sealing plate. The longitudinal beams extend along the moving direction of the mobile platform, the crossbeams intersect with the extending direction of the longitudinal beams and are connected to the longitudinal beams, and the sealing plate is disposed in the area enclosed by the crossbeams and the longitudinal beams.

[0029] In the above technical solution, the overall structural strength of the mobile platform can be improved by the cross-connection and cooperation of the crossbeams and longitudinal beams. By setting the sealing plate in the area enclosed by the crossbeams and longitudinal beams, the hollow area on the mobile platform is reduced, which can provide more installation positions for the installation of components such as the charging plug-in assembly, support rollers, guide rollers, and scrapers on the mobile platform. It also plays a shielding role, reducing the risk of dust, rainwater and other substances entering the storage space from the bottom of the mobile platform.

[0030] According to some embodiments of the present invention, the charging device further includes a first driving component, the first driving component including a first driving member, a first fixing member and a first moving member, the first fixing member being immovable relative to the seating position in the moving direction of the moving platform, the first moving member being connected to the moving platform, and the first driving member being configured to drive the first moving member to move relative to the first fixing member, so as to drive the moving platform to move along the moving guide rail.

[0031] In the above technical solution, by setting the first driving component, the automatic driving of the mobile station and the positioning of the external equipment can be realized, thereby improving the automation level of the charging device, reducing labor costs, and improving charging efficiency.

[0032] According to some embodiments of the present invention, the active module includes a first moving module, which is movably mounted on the mobile platform along a first direction. The plug-in module is disposed on the first moving module and is movable relative to the mobile platform along the first direction with the first moving module. The charging connector is plugged into the charging port along the first direction, where the first direction is the length direction of the external device.

[0033] In the above technical solution, the first moving module drives the plugging and unplugging module to move relative to the moving platform along the first direction, thereby realizing the plugging and unplugging of the charging connector and the charging port, realizing automatic plugging and unplugging charging, and improving charging automation and charging efficiency.

[0034] According to some embodiments of the present invention, the active module further includes a second moving module, which is movably mounted on the first moving module along a second direction. The plug-in module is disposed on the second moving module and is movable relative to the moving platform along the first direction and the second direction with the first moving module and the second moving module. The second direction is the width direction of the external device.

[0035] In the above technical solution, the second moving module drives the plug-in module to move along the second direction, allowing the charging connector to adjust its relative position to the charging port before plugging and unplugging for charging. For example, the position of the plug-in module in the second direction can be adjusted slightly to more accurately align the charging connector with the charging port, improving the plugging accuracy; alternatively, the position of the plug-in module in the second direction can be adjusted significantly to allow the same plug-in module to alternately plug into multiple charging ports on multiple charging panels of external devices, enabling charging of multiple external devices.

[0036] According to some embodiments of the present invention, the external device includes a plurality of charging panels, which are arranged sequentially along the second direction at one end of the external device facing the charging plug assembly. The charging plug assembly includes one unit, which is movable relative to the external device along the second direction to engage with any one of the plurality of charging panels.

[0037] In the above technical solution, a single charging plug assembly can meet the charging needs of external devices with multiple charging panels, reducing the cost of the charging device and improving its applicability.

[0038] According to some embodiments of the present invention, the active module further includes a third moving module, which is movably mounted on the second moving module along a third direction. The plug-in module is disposed on the third moving module. The plug-in module is movable relative to the charging base along the first moving module, the second moving module, and the third moving module along the first direction F1, the second direction F2, and the third direction F3, where the third direction is the height direction of the external device.

[0039] In the above technical solution, the first moving module, the second moving module and the third moving module enable the plug-in module to have the freedom of movement along the first direction, the second direction and the third direction. The plug-in module can be controlled to move along the first direction, the second direction and the third direction to adjust the position of the plug-in module, so that the charging connector of the plug-in module is more accurately aligned with the charging port, thereby improving the plugging accuracy of the charging connector and the charging port.

[0040] According to some embodiments of the present invention, the charging device further includes a protective cover, which is installed on the mobile platform and has a receiving space. The charging plug assembly is located in the receiving space. The protective cover is provided with a mating interface, and the movable module can drive the charging connector to extend from the mating interface to cooperate with the charging port on the external device.

[0041] In the above technical solution, by setting a protective cover, the charging plug assembly can be shielded and protected, achieving protection functions such as rainproof, snowproof, hailproof, dustproof, and sunproof. This helps to improve the service life of the charging plug assembly and enhance the reliability of the charging connection between the charging plug assembly and external devices.

[0042] According to some embodiments of the present invention, a shielding member is provided at the interface, the shielding member extends along the edge of the interface and is used to contact and cooperate with the outer wall of the external device.

[0043] In the above technical solution, the shielding component blocks the gap between the edge of the interface and the outer wall of the external device, so that the electrical connection between the charging connector and the charging port is not easily exposed to rain or ultraviolet radiation, which greatly reduces the risk of water ingress and aging, and improves the service life of the charging plug assembly.

[0044] According to some embodiments of the present invention, the protective cover is further provided with a protective curtain, which is located at the interface and is used to cover and open the interface.

[0045] In the above technical solution, by setting a protective curtain, the protective curtain can block the interface when the protective cover is not in conjunction with an external device, thus improving the protective effect of the protective cover when it is not charging. When charging is required, the protective cover is in conjunction with an external device, and the protective curtain can open the interface to facilitate the connection and charging of the charging assembly with the external device.

[0046] Another objective of this invention is to provide a charging system having the aforementioned charging device.

[0047] The charging system according to an embodiment of the present invention includes a seating frame and the charging device described above. The seating frame is connected to the charging device and is used to place the external device.

[0048] The above technical solutions can reduce the difficulty of docking, reduce the risk of plugging and unplugging failure, improve charging efficiency, and at the same time reduce the risk of damage to the docking structure between the plugging and unplugging module and external devices.

[0049] According to some embodiments of the present invention, the charging system is used to charge a box-type power supply, which is a replaceable power supply for electric ships.

[0050] The above technical solutions enable electric vessels to swap batteries, reducing charging and swapping waiting time; and the box-type power supply can utilize the charging system for shore charging, which is not limited by the location of the electric vessel, making charging time more flexible, and improving the docking accuracy between the charging system and the box-type power supply.

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.

[0060] In this utility model, "multiple" refers to two or more (including two).

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] In related technologies, the charging connector of the charging device and the charging port of the box-type power supply 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 charging port.

[0067] Based on this, this application proposes a charging device, including a charging plug-in assembly and a mobile platform. The charging plug-in assembly includes a movable module and a plug-in module. The plug-in module is provided with a charging connector. The plug-in module is located on the movable module. The movable module is used to drive the charging connector on the plug-in module to cooperate with the charging port on an external device to charge the external device. The charging plug-in assembly is mounted on the mobile platform. The external device has a seating position. The mobile platform is movable relative to the seating position to move closer to and further away from the external device.

[0068] In the embodiments of this application, when charging an external device is required, the charging plug-in assembly can be moved closer to the external device by a moving stage for initial positioning. Then, the degrees of freedom of the movable module are used for further positioning and plug-in charging. This helps improve the docking accuracy between the charging connector and the charging port, reduces the docking failure rate, improves charging efficiency, and reduces the risk of damage to the charging connector and the charging port. After charging is completed, the charging plug-in assembly can be moved away from its seated position by the moving stage to provide sufficient operating space for the transfer of the external device.

[0069] The charging device in this embodiment is used in a charging system, which can be used to charge external devices such as box-type power supplies. The external devices can be, but are not limited to, energy storage systems for electric ships, spacecraft, etc., where spacecraft can include airplanes, rockets, space shuttles, and spacecraft.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] The charging device 2 and charging system 1 according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0074] Reference Figures 4-8 As shown, Figure 5 This is a bottom view of the cooperative structure of the charging base 10 and the moving platform 40 according to an embodiment of the present utility model; Figure 6 This is a partial structural side view of the charging device 2 according to an embodiment of the present utility model; Figure 7 This is a schematic diagram of the cooperation structure between the charging base 10 and the moving platform 40 according to an embodiment of the present utility model; Figure 8 yes Figure 7 The enlarged structural diagram at point A is shown in the center circle. According to an embodiment of the present invention, the charging device 2 is used to charge external devices. The charging device 2 may include: a charging plug-in assembly 30 and a moving platform 40.

[0075] Specifically, the charging and plugging assembly 30 includes a movable module 301 and a plugging module 35. The plugging module 35 is provided with a charging connector 351. The plugging module 35 is located on the movable module 301. The movable module 301 is used to drive the charging connector 351 on the plugging module 35 to cooperate with the charging port on the external device to charge the external device. The charging and plugging assembly 30 is mounted on a mobile platform 40. The external device has a seating position. The mobile platform 40 is movable relative to the seating position to move closer to and away from the external device.

[0076] Charging plugging and unplugging refers to the process of inserting or unplugging the charging port of an external device during the charging process. For example, inserting or unplugging the charging connector 351 of the plugging and unplugging module 35 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 mechanism, and is one of the operations of device charging.

[0077] The charging plug-in assembly 30 refers to a component that can charge external devices through charging plug-in. The plug-in module 35 is a component that directly connects to external devices. The moving module 301 is a component used to drive the charging connector 351 on the plug-in module 35 to move relative to the moving stage 40. The movement includes, but is not limited to, linear movement, curved movement, and rotation in at least one direction.

[0078] By driving the charging connector 351 on the plug-in module 35 to move via the active module 301, the charging plug-in assembly 30 can achieve free-degree positioning, enabling the adjustment of the position of the charging connector 351 relative to the charging port. In some embodiments, the angle of the charging connector 351 relative to the charging port can also be adjusted. After adjustment, the active module 301 can also drive the charging connector 351 to plug into the charging port for charging. After charging is completed, the active module 301 can also drive the charging connector 351 to separate from the charging port. Thus, the plug-in charging process is completed.

[0079] 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.

[0080] For example, the charging plug-in 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 activity module 301 can control the charging connector 351 on the plug-in module 35 to adjust its posture according to the identification result of the identification component.

[0081] The seating position refers to the charging station used to place external equipment during the charging process. The seating position can be a fixed area on the ground or a fixed position on a tool (such as the seating frame 20) placed on the ground.

[0082] The charging plug 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 a guide rail or other structure. As long as the movement of the mobile platform 40 can move the charging plug assembly 30 relative to the seat position.

[0083] The moving platform 40 can move along a straight or curved path relative to the seating position, as long as the movement changes the distance between the moving platform 40 and the external device. For example, the seating position of the external device can be located on one side of the charging base 10 in the first direction F1. The moving platform 40 can move back and forth in a straight line along the first direction F1 to move the charging plug assembly 30 on the moving platform 40 closer to and away from the external device. The moving platform 40 moves the charging plug assembly 30 closer to the external device, making the distance between the charging plug assembly 30 and the external device closer, so that the relative position and relative angle between the charging connector 351 and the charging port of the external device can be adjusted more accurately by the movable module 301, thereby improving the charging plug efficiency and accuracy. After charging is completed, the moving platform 40 moves the charging plug assembly 30 away from the external device to avoid interfering with the transfer of the external device.

[0084] According to the embodiment of the present invention, the charging device 2 moves the charging plug assembly 30 relative to the seating position of the external device via the moving platform 40 to achieve initial positioning of the charging plug assembly 30 with the external device. The moving module 301 of the charging plug assembly 30 moves the charging connector 351 of the plug module 35 to achieve further positioning of the charging connector 351 with the charging port of the external device. This enables the charging connector 351 and the charging port to achieve more precise positioning and matching, reducing docking difficulty, reducing the risk of plugging failure, improving charging efficiency, and reducing the risk of damage to the docking structure of the charging connector 351 and the charging port.

[0085] According to some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the mobile station 40 has a first position and a second position arranged along a first direction F1. The first position is a seating position that is far away from the external device relative to the second position. When there is no external device at the seating position, the mobile station 40 is located in the first position.

[0086] When the mobile station 40 is in the first position, the distance between it and the seating position is greater. When there are no external devices at the seating position, the mobile station 40 is in the first position, which makes the space near the seating position larger. When placing external devices at the seating position, it is less likely to interfere with or collide with the mobile station 40, thus improving the convenience of seating.

[0087] In the embodiments of this application, the movement control method for the mobile stage 40 to move between the first position and the second position can be flexibly set. Optionally, the mobile stage 40 can be driven to move a fixed distance by a driving structure (such as the first driving component 46) to achieve switching between the first position and the second position; the charging device 2 may also include a limiting structure disposed at the first position and the second position, and the mobile stage 40 automatically stops moving when it moves to the first position or the second position and abuts against the limiting structure; the charging device 2 may also include a detection structure that detects that the mobile stage 40 has moved to the correct position when it moves to the first position or the second position and controls the mobile stage 40 to stop moving, etc.

[0088] In some embodiments, such as Figure 4 As shown, the charging device 2 also includes a second position positioning structure 56, which is triggered to operate when the mobile stage 40 is in the second position.

[0089] The specific structure and detection method of the second position positioning structure 56 can be flexibly set according to the actual situation. For example, the second position positioning structure 56 can detect whether the moving stage 40 has moved into place by infrared detection, contact detection, ultrasonic detection and other methods.

[0090] In some embodiments, such as Figure 4 As shown, the second position positioning structure 56 includes a probe. When the moving stage 40 approaches the external device and moves to the second position, the probe comes into contact with the outer wall of the external device, triggering the second position positioning structure 56. Detecting whether the device has moved to the second position by contacting the probe with the outer wall of the external device provides higher accuracy and is unaffected by factors such as weather.

[0091] By setting a second positioning structure 56, the second positioning structure 56 can detect the initial positioning status of the mobile station 40 and the external device, so that it can be triggered and take corresponding measures when the initial positioning is completed, such as controlling the mobile station 40 to stop moving when the initial positioning is completed.

[0092] In some specific embodiments, such as Figure 3 and Figure 4 The charging device 2 shown includes a protective cover 50, which includes a cover body 51, a shielding member 52 disposed on the cover body 51, and a protective curtain 55. A second position positioning structure 56 can be disposed on the cover body 51. When the moving platform 40 approaches the external device and moves to the second position, it indicates that the shielding member 52 is in contact with the outer wall of the external device. At this time, the second position positioning structure 56 is triggered, and the protective curtain 55 is configured to open the interface 512 of the cover body 51 when the second position positioning structure 56 is triggered. By setting the second position positioning structure 56, water can be prevented from entering the interface 512 when the protective curtain 55 opens it when the shielding member 52 is not properly engaged with the outer wall of the external device, thus effectively improving the rainproof effect.

[0093] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the external device is a box-type power supply 90, and the moving platform 40 is located at the end of the box-type power supply 90 along the first direction F1. The moving platform 40 moves closer to and further away from the box-type power supply 90 along the first direction F1, where the first direction F1 is the length direction of the box-type power supply 90.

[0094] The moving stage 40 moves along the length of the box-type power supply 90, enabling the charging plug-in assembly 30 to move along the length of the box-type power supply 90. The moving path of the moving stage 40 is more regular and better matched to the box-type structure of the box-type power supply 90, which is more conducive to improving the initial positioning effect of the charging plug-in assembly 30 relative to the box-type power supply 90.

[0095] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the charging device 2 also includes a charging base 10, which has a movable guide rail 11. The movable platform 40 is mounted on the charging base 10 and can move along the movable guide rail 11. The charging base 10 is not movable relative to the seated position.

[0096] 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 that are arranged crosswise and connected.

[0097] The movable guide rail 11 can extend along a straight or curved path, requiring only that the movable guide rail 11 has one end close to the seating position and one end far from the seating position. For example, the movable guide rail 11 can extend along a straight line in the first direction F1.

[0098] The charging base 10 can be connected to a structure with a seating position (such as a seating frame 20) (e.g., by fasteners, welding, etc.) so that the charging base 10 is immovable relative to the seating position; or, the charging base 10 and the structure with the seating position can be fixedly installed on the ground respectively so that the charging base 10 is immovable relative to the seating position.

[0099] The charging base 10 and the movable guide rail 11 on the charging base 10 provide support and guidance for the movement of the moving stage 40 and the components on the moving stage 40, making the movement of the moving stage 40 more stable, which is beneficial to improving positioning accuracy and reducing the likelihood of jamming during movement. Furthermore, since the charging base 10 is immovable relative to the seating position, the distance the moving stage 40 moves along the movable guide rail 11 is the same as the distance it moves relative to the seating position, making the movement control of the moving stage 40 simpler and the positioning accuracy higher.

[0100] According to some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the mobile station 40 has a positioning part 41 at one end facing the external device, and the charging base 10 is connected to a positioning member 22. When the mobile station 40 is in the second position, the positioning member 22 and the positioning part 41 cooperate with each other.

[0101] The specific structure and engagement method of the positioning element 22 and the positioning part 41 can be flexibly set. For example, the positioning part 41 can be a positioning notch, and when the moving stage 40 is in the second position, the positioning element 22 is located within the positioning notch.

[0102] A positioning notch refers to an area formed on one edge of the moving platform 40 and recessed away from the seating position. The shape of the positioning notch includes, but is not limited to, square, semi-circular, etc. The positioning element 22 can be in contact with or clearance fit the edge of the positioning notch.

[0103] The positioning component 22 can be an integral structure formed on the charging base 10, or it can be a component connected to the charging base 10. For example, in some embodiments, the seating frame 20 for placing external devices is connected to the charging base 10. The seating frame 20 is provided with a guide component 21 for guiding and limiting the external devices. Some guide components 21 can be used as positioning components 22 to cooperate with the moving platform 40 to play a positioning role, and to make the positioning notch 41 play a avoidance role, so as to prevent the moving platform 40 from interfering with the seating frame 20 during the movement. The guide component 21 is functionally integrated and has a compact structure.

[0104] The positioning element 22 and the positioning part 41 can position the movement of the mobile stage 40, making the position of the mobile stage 40 relative to the seating position and the external device located at the seating position more accurate when it moves to the second position. For example, if the positioning part 412 is a positioning notch, the distance that the mobile stage 40 moves along the first direction F1 towards the seating position will not be too large and will not damage the external device or other components. In addition, the mobile stage 40 is less likely to deviate from the first direction F1 (such as along the second direction F2) and reduce the initial positioning accuracy.

[0105] According to some embodiments of this utility model, such as Figures 6-9 As shown, Figure 9 This is a schematic diagram of the structure at the interface between the support roller 42 and the movable guide rail 11 according to an embodiment of the present invention. The movable table 40 is provided with the support roller 42, which is rotatably supported on the upper surface of the movable guide rail 11.

[0106] 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.

[0107] 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.

[0108] 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 to the movement of the moving table 40, thereby improving the accuracy of the movement stroke control of the moving table 40 and improving the movement efficiency.

[0109] In some embodiments, such as Figure 7 As shown, there are two movable guide rails 11, which are spaced apart along the axial direction of the support roller 42 (e.g., the second direction F2). The outer peripheral surface of the support roller 42 includes a conical surface 421, which contacts and engages with the upper surface of the movable guide rail 11. In the two movable guide rails 11 corresponding to the support roller 42, the smaller ends of the conical surfaces 421 are close to each other, while the larger ends are far apart.

[0110] The movable platform 40, in conjunction with the two movable guide rails 11, provides more stable support for the movable platform 40 from the charging base 10, making it less prone to tipping over. The conical surface 421 of the support roller 42 contacts and engages with the movable guide rails 11, ensuring that the support roller 42 experiences a force close to the center of the movable platform 40 along its axial direction during rotation. This, in turn, allows the support rollers 42 on the two movable guide rails 11 to level the movable platform 40, preventing it from tilting or tipping over.

[0111] In some specific embodiments, the taper of the conical surface 421 is 1° to 2°.

[0112] The taper of the conical surface 421 refers to the angle between the conical surface 421 and the axis of the supporting roller 42, i.e., 1°≤α≤2°. In some specific embodiments, the taper of the conical surface 421 can be 1°, 1.2°, 1.5°, 1.7°, and 2°, etc.

[0113] If the taper of the conical surface 421 is too large, it will cause point or line contact between the conical surface 421 and the moving guide rail 11, resulting in high stress, reducing the lifespan of the support roller 42 and the moving guide rail 11, and reducing the stability of the moving table 40. If the taper of the conical surface 421 is too small, it will reduce the leveling effect. Within the above-mentioned taper range, the goals of improving the leveling effect and reducing stress are balanced.

[0114] In some embodiments, such as Figures 7-9 As shown, the outer peripheral surface of the support roller 42 is provided with a limiting flange 422. In the axial direction of the support roller 42, the limiting flange 422 is located on the side of the moving guide rail 11 away from the center of the moving table 40.

[0115] In the radial direction of the support roller 42, the limiting flange 422 protrudes from the outer peripheral surface of the support roller 42. The limiting flange 422 can be an annular protrusion integrally formed on the support roller 42, or it can be a flange or the like connected to the support roller 42.

[0116] It should be noted that during the movement of the moving stage 40, the limiting flange 422 can contact and cooperate with the moving guide rail 11 to improve the limiting effect. The limiting flange 422 can also be spaced apart from the moving guide rail 11 by a certain gap, so as to reduce the rotational resistance of the supporting roller 42 while ensuring that the offset dimension of the moving stage 40 is within the allowable range.

[0117] With the outer circumferential surface of the support roller 42 supported by the moving guide rail 11, the limiting flange 422 can be located on the side of the moving guide rail 11 away from the center of the moving stage 40. When the moving stage 40 deviates in the axial direction of the support roller 42, the limiting flange 422 can cooperate with the side of the moving guide rail 11 to limit the movement, preventing the moving stage 40 from deviating or from deviating too much, which would affect the positioning of the charging plug-in assembly 30 and the external device. This helps to improve positioning accuracy and reduce the risk of the moving stage 40 derailing.

[0118] According to some embodiments of this utility model, such as Figure 7 , Figure 8 and Figure 10 As shown, Figure 10 This is a schematic diagram of the structure at the interface between the guide roller 43 and the movable guide rail 11 according to an embodiment of the present invention. The movable table 40 is provided with a guide roller 43, the axis of which is parallel to the vertical direction, and the guide roller 43 rolls in contact with the side of the movable guide rail 11 away from the center of the movable table 40.

[0119] The guide roller 43 can be made of corrosion-resistant and high-strength materials such as nylon and stainless steel, which can provide good guidance for the movement of the moving platform 40 and are not easily corroded or damaged by contact with rainwater, mud, etc.

[0120] The number of guide rollers 43 can be flexibly set according to the actual situation. Specifically, there can be one or more guide rollers 43, and each moving guide rail 11 can cooperate with one or more guide rollers 43. The multiple guide rollers 43 corresponding to the same moving guide rail 11 are spaced apart along the extension direction of the moving guide rail 11.

[0121] For example, in an embodiment that includes two movable guide rails 11, such as Figure 7 As shown, the movable guide rail 11 extends along the first direction F1 and the two movable guide rails 11 are spaced apart along the second direction F2. Each movable guide rail 11 is equipped with a plurality of guide rollers 43 and the plurality of guide rollers 43 are spaced apart along the extension direction of the movable guide rail 11. The guide rollers 43 on the two movable guide rails 11 are located on opposite sides of the two movable guide rails 11.

[0122] By cooperating with the side of the guide roller 43 opposite to the center of the moving platform 40 of the moving guide rail 11, the guide roller 43 and the moving guide rail 11 can interfere in a direction perpendicular to the moving direction (in the second direction F2) to limit the movement of the moving platform 40 in a direction perpendicular to the moving direction, so that the moving platform 40 can move stably along the moving guide rail 11 and improve the initial positioning effect of the charging plug-in assembly 30 and the external device.

[0123] According to some embodiments of this utility model, such as Figure 7 , Figure 8 and Figure 11 As shown, Figure 11 This is a schematic diagram of the structure at the interface between the scraper 44 and the moving guide rail 11 according to an embodiment of the present invention. The moving table 40 is provided with a scraper 44, and the scraper 44 and the moving guide rail 11 are in clearance fit.

[0124] The charging device 2 can be used in outdoor environments such as riverbanks, where rainwater and mud easily accumulate on the moving guide rail 11. If not cleaned in time, this will affect the movement of the moving platform 40 and reduce the support and guiding reliability of the support rollers 42 and guide rollers 43. By providing a scraper 44, which can move with the moving platform 40 relative to the moving guide rail 11, the scraper 44 can remove mud and other deposits adhering to the surface of the moving guide rail 11, thereby improving the stability of the support rollers 42 and guide rollers 43 as they roll along the moving guide rail 11.

[0125] In some embodiments, such as Figure 11 As shown, the scraper 44 is provided with a downward-opening scraper groove 441, which extends through the scraper 44 along the extension direction of the moving guide rail 11, and at least the upper part of the moving guide rail 11 is located in the scraper groove 441.

[0126] The downward-opening scraper groove 441 has a bottom surface located above the moving guide rail 11 and two side surfaces located on both sides of the moving guide rail 11. With at least the upper part of the moving guide rail 11 located within the scraper groove 441, the bottom surface of the scraper groove 441 can scrape away deposits from the upper surface of the moving guide rail 11, and the side surfaces of the scraper groove 441 can scrape away deposits from the sides of the moving guide rail 11. This allows the support roller 42 to stably engage with the upper surface of the moving guide rail 11, and the guide roller 43 to stably engage with the side surfaces of the moving guide rail 11. The scraper groove 441 provides a more comprehensive cleaning effect on the deposits on the moving guide rail 11.

[0127] The shape of the scraper groove 441 can be adapted to the shape of the moving guide rail 11 to improve the scraping effect of the attached material. In some specific embodiments, refer to... Figure 11As shown, the cross-section of the moving guide rail 11 perpendicular to the extension direction includes a first extension segment 111, a second extension segment 112, and a third extension segment 113. The first extension segment 111 is located above and spaced apart from the second extension segment 112, and the third extension segment 113 connects the middle of the first extension segment 111 and the middle of the second extension segment 112. The cross-section of the scraper groove 441 perpendicular to the extension direction of the moving guide rail 11 includes a first groove 442 and a second groove 443. The second groove 443 extends in the vertical direction, is located below the first groove 442, and communicates with the middle of the first groove 442. In other words, the cross-section of the moving guide rail 11 is generally I-shaped, and the cross-section of the scraper groove 441 is generally T-shaped.

[0128] The support roller 42 rolls on the first extension 111, allowing a sufficiently large contact area between the support roller 42 and the first extension 111 to improve support stability. The roller rolls laterally with the first extension 111, ensuring stable guidance while minimizing the contact area between the guide roller 43 and the first extension 111 to reduce movement resistance. The first extension 111 is located in the first groove 442, the third extension 113 is located in the second groove 443, and the second extension 112 is located outside the scraper groove 441 and connected to the moving platform 40. This ensures that the shape of the scraper groove 441 matches the shape of the moving guide rail 11, improving the removal of deposits from different areas of the moving guide rail 11.

[0129] The support rollers 42, guide rollers 43, and scraper 44 can be directly mounted to the moving table 40, or they can be mounted to the moving table 40 through other structures. For example... Figures 7-11 As shown, the moving platform 40 is provided with a first bracket 471, a second bracket 472 and a third bracket 473. The supporting roller 42 is rotatably mounted on the first bracket 471, the guide roller 43 is rotatably mounted on the second bracket 472, and the scraper 44 is provided on the third bracket 473. Here, the scraper 44 and the third bracket 473 can be integrally formed or connected together by welding, fasteners or other means.

[0130] According to some embodiments of this utility model, such as Figure 5 As shown, the moving platform 40 includes multiple crossbeams 451, multiple longitudinal beams 452, and a sealing plate 453. The longitudinal beams 452 extend along the moving direction of the moving platform 40. The crossbeams 451 intersect with the extending direction of the longitudinal beams 452 and are connected to the longitudinal beams 452. The sealing plate 453 is located in the area enclosed by the crossbeams 451 and the longitudinal beams 452.

[0131] The extension directions of the crossbeams 451 and the longitudinal beams 452 can be perpendicular to each other or at a certain angle. The crossbeams 451 and longitudinal beams 452 are connected to form a frame structure. It is worth noting that the number of crossbeams 451 can be two or more, and the total number can be two or more. Each crossbeam 451 can be connected to one or more longitudinal beams 452, and each longitudinal beam 452 can be connected to one or more crossbeams 451. The area enclosed by the crossbeams 451 and longitudinal beams 452 can be one or more, and the shape of the enclosed area can be, but is not limited to, square, circular, or irregular shapes. In embodiments where the crossbeams 451 and longitudinal beams 452 enclose multiple areas, the sealing plates 453 at the multiple areas can be separate components or a single piece.

[0132] By connecting the crossbeams 451 and 452, the overall structural strength of the mobile platform 40 can be improved. By setting the sealing plate 453 in the area enclosed by the crossbeams 451 and 452, the hollow area on the mobile platform 40 is reduced, which can provide more installation positions for the charging plug-in assembly 30, support rollers 42, guide rollers 43, scraper 44 and other components on the mobile platform 40. It also plays a shielding role, reducing the risk of dust, rainwater and other pollutants entering the accommodating space 511 from the bottom of the mobile platform 40.

[0133] According to some embodiments of this utility model, such as Figures 4-7 As shown, the charging device 2 also includes a first driving assembly 46, which includes a first driving member 461, a first fixing member 462, and a first moving member 463. The first fixing member 462 is immovable relative to the seating position in the moving direction of the moving platform 40. For example, the first fixing member 462 can be connected to the charging base 10 so that it is immovable relative to the seating position in the first direction F1. The first moving member 463 is connected to the moving platform 40, and the first driving member 461 is configured to drive the first moving member 463 to move relative to the first fixing member 462, thereby causing the moving platform 40 to move relative to the seating position.

[0134] The first fixing member 462 is immovable relative to the seating position in the moving direction of the moving table 40, 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 first direction F1. This application does not limit this.

[0135] The first moving part 463 is a component that can move with the moving table 40 relative to the seated position. Of course, the first moving part 463 may or may not have other forms of motion during the movement process, such as rotation with the rotation axis parallel to the first direction F1. This application does not limit this.

[0136] The first driving component 461 can be, but is not limited to, an electric cylinder, a servo motor, etc.

[0137] The first 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 first 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 in the direction of approaching and moving away from the seat position. Taking the first direction F1 as an example. Alternatively, the first driving member 461 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 463 includes a sleeve and a nut. The nut is located inside the sleeve. The nut is fixed relative to the sleeve in the first direction F1 and can rotate relative to the sleeve. The nut has an internal thread and engages with the external thread of the first fixed member 462. The first driving member 461 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 in the first direction F1.

[0138] 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.

[0139] By setting the first drive component 46, the mobile station 40 can be automatically driven to position itself with external equipment, thereby improving the automation level of the charging device 2, reducing labor costs, and increasing charging efficiency.

[0140] In some embodiments, such as Figure 4 and Figure 6 As shown, the activity module 301 includes a first moving module 31, which is movably mounted on the mobile platform 40 along a first direction F1. A plug-in module 35 is disposed on the first moving module 31. The plug-in module 35 moves relative to the mobile platform 40 along the first direction F1 with the first moving module 31. A charging connector 351 is plugged into the charging port along the first direction F1. The first direction F1 is the length direction of the external device.

[0141] The first moving module 31 moves relative to the moving platform 40 along the first direction F1, thereby driving the plugging and unplugging module 35 to move relative to the moving platform 40 along the first direction F1, thereby realizing the plugging and unplugging cooperation between the charging connector 351 and the charging port, realizing automatic plugging and unplugging charging, and improving charging automation and charging efficiency.

[0142] In some embodiments, such as Figure 4 and Figure 6As shown, the activity module 301 also includes a second moving module 32, which is movably mounted on the first moving module 31 along the second direction F2. The plug-in module 35 is disposed on the second moving module 32. The plug-in module 35 is movable relative to the moving platform 40 along the first moving module 31 and the second moving module 32 along the first direction F1 and the second direction F2. The second direction F2 is the width direction of the external device.

[0143] The first moving module 31 drives the plug-in module 35 to move along the first direction F1, and the second moving module 32 drives the plug-in module 35 to move along the second direction F2, giving the charging connector 351 degrees of freedom in both directions F1 and F2. This allows the relative position of the charging connector 351 and the charging port to be adjusted before plugging and unplugging for charging. For example, the position of the plug-in module 35 in the second direction F2 can be adjusted slightly to make the charging connector 351 more precisely aligned with the charging port of the charging panel 91, improving the plugging accuracy between the charging connector 351 and the charging port in the charging panel 91. Alternatively, the position of the plug-in module 35 in the second direction F2 can be adjusted significantly to allow the same plug-in module 35 to alternately plug into the charging ports on multiple charging panels 91 of external devices, enabling charging of multiple external devices.

[0144] In some specific embodiments, such as Figures 1-4 and Figure 6 As shown, the external device includes a plurality of charging panels 91, which are arranged sequentially along a second direction F2 at one end of the external device facing the charging plug assembly 30. The charging plug assembly 30 includes one unit that is movable relative to the external device along the second direction F2 to engage with any one of the plurality of charging panels 91.

[0145] For example, the second moving module 32 can drive the plug-in module 35 to move between multiple positions arranged sequentially along the second direction F2, so that the plug-in module 35 can be directly opposite one of the multiple charging panels 91 at any position. At this time, the first moving module 31 can drive the charging connector 351 to plug into the charging port on the charging panel 91 to charge the circuit corresponding to the charging panel 91. After the circuit is charged, the second moving module 32 can drive the plug-in module 35 to move in the second direction F2 to be directly opposite other charging panels 91 at other positions, and plug into the charging port on the currently directly opposite charging panel 91. In this way, the charging of multiple circuits corresponding to multiple charging panels 91 can be realized.

[0146] Therefore, a single charging plug assembly 30 can meet the charging needs of external devices with multiple charging panels 91, reducing the cost of the charging device 2 and improving its applicability.

[0147] In some embodiments, such as Figure 4 and Figure 6 As shown, the activity module 301 includes a third moving module 33, which is movably mounted on the second moving module 32 along a third direction F3. A plug-in module 35 is disposed on the third moving module 33. The plug-in module 35 is movable relative to the mobile stage 40 along the first direction F1, the second direction F2 and the third direction F3 of the first moving module 31, the second moving module 32 and the third moving module 33. The third direction F3 is the height direction of the external device 90.

[0148] In the above embodiments, the first mobile module 31 can be directly or indirectly disposed on the mobile station 40, the second mobile module 32 can be directly or indirectly installed on the first mobile module 31, the third mobile module 33 can be directly or indirectly installed on the second mobile module 32, and the pluggable module 35 can be directly or indirectly disposed on the third mobile module 33. For example Figure 4 The 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.

[0149] The first moving module 31, the second moving module 32, and the third moving module 33 enable the plug-in module 35 to have degrees of freedom of movement along the first direction F1, the second direction F2, and the third direction F3. This allows the plug-in module 35 to be moved along the first direction F1, the second direction F2, and the third direction F3 to adjust its position, thereby making the charging connector 351 of the plug-in module 35 more accurately aligned with the charging port and improving the plugging accuracy of the charging connector 351 and the charging port.

[0150] The first moving module 31, the second moving module 32, the third moving module 33, and the plug-in module 35 can each be one, two, or more. The position of the same plug-in module 35 can be adjusted so that it can alternately plug into 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 plug-in module 35 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 one third moving module 33, and each third moving module 33 has a plug-in module 35, so that the plug-in modules 35 on the two third moving modules 33 can be plugged into two charging panels 91 respectively, achieving charging of the dual-loop external device.

[0151] By using the first moving module 31, the second moving module 32, and the third moving module 33, the control accuracy of the displacement of the plug-in module 35 along the first direction F1, the second direction F2, and the third direction F3 can be improved, thereby improving the control accuracy of the position of the plug-in module 35. This allows the plug-in module 35 to be accurately electrically connected to the corresponding charging panel 91. The plug-in accuracy and success rate of the same plug-in module 35 when plugged into one charging panel 91 or alternately plugged into multiple charging panels 91 are higher, and it is also beneficial to realize automatic plug-in charging.

[0152] In some specific embodiments, the charging plug-in assembly 30 further includes a second drive assembly, a third drive assembly, and a fourth drive assembly. The second drive assembly drives the first moving module 31 to move relative to the moving platform 40, the third drive assembly drives the second moving module 32 to move relative to the first moving module 31, and the fourth drive assembly drives the third moving module 33 to move relative to the second moving module 32. The specific structures of the second, third, and fourth drive assemblies can be the same as or different from the first drive assembly 46. For example, the fixing member and the moving member can be connected by threads, or by rack and pinion, etc. This application does not impose any special limitations in this regard.

[0153] 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, the first moving module 31, the second moving module 32, and the third moving module 33 enable the plug-in module 35 to move along the first direction F1, the second direction F2, and the third direction F3 with high precision. This improves the plug-in accuracy between the plug-in module 35 and the corresponding charging panel 91, and also facilitates the alternating plugging of the same plug-in module 35 with different charging panels 91 of the external device, meeting the charging needs of different circuits in the external device, and achieving high plug-in accuracy.

[0154] According to some embodiments of this utility model, as shown in Figure - Figure 4 As shown, the charging device 2 also includes a protective cover 50. The protective cover 50 is mounted on the mobile platform 40 and has a receiving space 511, within which the charging plug-in assembly 30 is located. The protective cover 50 is provided with a docking interface 512, from which the movable module 301 can drive the charging connector 351 to extend and engage with a charging port on an external device.

[0155] The protective cover 50 and the mobile stage 40 can be connected by fasteners, connectors, etc. For example, the protective cover 50 and the mobile stage 40 can be connected by multiple connectors spaced apart along the circumference of the mobile stage 40. The connectors are bent plates, a part of which is connected to the cover 51 of the protective cover 50 by fasteners, and the other part of which is connected to the mobile stage 40 by fasteners.

[0156] The protective cover 50 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 of the protective cover 50 may include a top wall and a peripheral wall. The upper ends of the top wall and the peripheral wall are 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 can be cylindrical or a prismatic shape composed of multiple flat side walls. The material of the cover 51 can be, but is not limited to, high-strength low-carbon steel, aluminum alloy, stainless steel, composite materials (such as aluminum and insulation layer), etc.

[0157] Interface 512 refers to an opening provided on the protective cover 50. Interface 512 can penetrate the protective cover 50 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 protective cover 50, for example... Figure 3 and Figure 4 As shown, the cover 51 of the protective cover 50 includes multiple sidewalls, one of which faces the external equipment and has a connection interface 512.

[0158] The protective cover 50 may have one or more connection interfaces 512, wherein the multiple connection interfaces 512 may be located on the same wall surface of the protective cover 50 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 simultaneously through multiple connection interfaces 512.

[0159] By setting up a protective cover 50, the charging plug assembly 30 can be shielded and protected, achieving protection functions such as rainproof, snowproof, hailproof, dustproof, and sunproof. This helps to improve the service life of the charging plug assembly 30 and enhance the reliability of the charging connection between the charging plug assembly 30 and external devices.

[0160] In some embodiments, continue to refer to Figure 3 and Figure 4 As shown, a shielding member 52 is provided at the interface 512. The shielding member 52 extends along the edge of the interface 512 and is used to contact and cooperate with the outer wall of the external device.

[0161] The fixing method of the shielding member 52 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 interface 512. Here, the shielding member 52 can extend along the periphery of the interface 512 in a non-complete ring shape (for example, the shielding member 52 is provided on the peripheral wall of the cover 51, and the bottom of the shielding member 52 is a ring-shaped break), or it can extend into a complete ring shape. Here, the ring shape can be, but is not limited to, a circular ring and a square ring.

[0162] 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.

[0163] 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 of the external device for charging. During charging, the shield 52 covers the gap between the protective cover 50 and the outer wall of the external device, specifically covering the gap between the edge of the interface 512 and the charging panel 91. This prevents the electrical connection between the charging connector 351 and the charging port 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.

[0164] According to some embodiments of this utility model, such as Figure 4 As shown, the shielding member 52 is provided with a water guiding channel 53. The water guiding channel 53 includes a first channel segment, which is disposed on the top of the shielding member 52 and extends along a second direction F2, which intersects with the first direction F1. At least one end of the first channel segment in the second direction F2 extends to the edge of the shielding member 52.

[0165] 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 along the first direction F1 and the gap is blocked by the shielding member 52.

[0166] The water guide channel 53 can guide water flow during rain and snow to reduce the risk of water flowing to external equipment or between the enclosure 51 and the shield 52, further reducing the risk of water ingress. Specifically, the first channel section is located at the top of the shield 52. When rainwater falls onto the shield 52, it can enter the first channel section at the top and flow along the first channel section 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 enclosure 51 and the shield 52, effectively improving the waterproof effect.

[0167] In some embodiments, the water guide channel 53 further includes a second channel segment, which is located on the side of the shield 52 and extends in a vertical direction, and the second channel segment communicates with the first channel segment. The second channel segment extends in a vertical direction, and here the second channel segment can be perpendicular to the vertical direction or at a certain angle to the vertical direction.

[0168] In embodiments where one end of the first channel extends to the edge of the shield 52 and the other end does not, the water channel 53 may include a second channel that communicates with the end of the first channel located at the edge of the shield 52. In some embodiments where both ends of the first channel extend to the edge of the shield 52, the water channel 53 may include a second channel that communicates with one end of the first channel. The water channel 53 may also include two second channels that communicate with the two ends of the first channel, respectively.

[0169] The water flowing in the first channel can flow downwards into the second channel for drainage. The first and second channels can restrict the flow path of the water, thus improving the waterproofing effect.

[0170] In some specific embodiments, the water guide channel 53 is composed of a first channel segment and two second channel segments, forming an n-shaped channel; in other specific embodiments, the water guide channel 53 is composed of a first channel segment, two second channel segments and a third channel segment, the third channel segment extends along the second direction F2 and its two ends are respectively connected to the lower ends of the second channel segments, the water guide channel 53 is formed into a U-shaped channel, and 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.

[0171] According to some embodiments of the present invention, as shown in the figures and... Figure 4 As shown, the protective cover 50 is also provided with a protective curtain 55, which is located at the interface 512 and is used to cover and open the interface 512.

[0172] 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 and cover the interface 512.

[0173] By setting up the protective curtain 55, when the protective cover 50 is not connected to an external device, 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 connected to an external device, and the protective curtain 55 can open the interface 512 to facilitate the connection and charging of the charging plug-in assembly 30 with the external device.

[0174] In some embodiments, the cover 51 may be provided with multiple interfaces 512, and the protective curtains 55 at at least two interfaces 512 are integral pieces. Thus, the integral protective curtains 55 can be driven to open and close 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.

[0175] like Figures 1-4 As shown, the charging system 1 according to an embodiment of the present invention includes a seating frame 20 and a charging device 2 according to an embodiment of the present invention. The seating frame 20 is connected to the charging device 2, for example, to the 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 above-mentioned beneficial technical effects, the charging system 1 according to an embodiment of the present invention moves the charging plug assembly 30 relative to the seating position of the external device by the moving platform 40 to achieve initial positioning of the charging plug assembly 30 with the external device. Furthermore, the charging connector 351 of the plug module 35 is moved by the movable module 301 of the charging plug assembly 30 to achieve further positioning of the charging connector 351 with the charging port of the external device. This allows the charging connector 351 and the charging port to achieve more precise positioning and matching, reducing docking difficulty, reducing the risk of plugging failure, improving charging efficiency, and reducing the risk of damage to the docking structure of the charging connector 351 and the charging port.

[0176] 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.

[0177] The mounting frame 20 of this application defines the mounting position of the external equipment. That is, by placing the 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 provides high charging efficiency for the external equipment and eliminates the need to build other devices for placing the external equipment in the battery swapping station, reducing the construction cycle and allowing for rapid commissioning.

[0178] In some embodiments, such as Figures 3-4 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 in the seating position.

[0179] 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.

[0180] In some embodiments, such as Figure 1 and Figure 2 As shown, the charging system 1 is used to charge the box-type power supply 90, which is a replaceable power source for electric vessels. This enables electric vessels to swap batteries, reducing charging and swapping waiting time. Furthermore, the box-type power supply 90 can be charged on shore using the charging system 1, without being restricted by the location of the electric vessel, making charging time more flexible and improving the docking accuracy between the charging system 1 and the box-type power supply 90.

[0181] 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.

[0182] like Figures 1-11 As shown, the charging system 1 according to a specific embodiment of the present invention includes a seating frame 20 and a charging device 2. The seating frame 20 is connected to the charging device 2 and is used to place external devices. The external devices have 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.

[0183] 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 third direction F3 are perpendicular to each other, and the third direction F3 is the vertical direction.

[0184] 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. Guide rollers 43 engage with the side of the moving guide rail 11 for guidance and to prevent deviation. A scraper 44 engages with the moving guide rail 11 to remove mud and dirt, improving the smoothness of the moving platform 40's movement. The first drive assembly 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 is hinged to the charging base 10. The extension and retraction of the electric cylinder drives the entire moving platform 40 to move linearly along the moving guide rail 11.

[0185] The protective cover 50 has a cover body 51 that covers the moving platform 40 and is fixedly connected to the moving platform 40 via connectors. The protective cover 50 has two square access ports 512 on its side wall facing the seating frame 20 in the first direction F1, and the two access ports 512 are spaced apart along the second direction F2. A second position positioning structure 56 is provided between the two access ports 512. A protective curtain 55 is provided inside the cover body 51. The protective curtain 55 is a roller shutter and is movable along the third direction F3 to open and cover the access ports 512. At the access ports 512, a blocking member 52 is fixedly connected to the cover body 51 via pressure strips and fasteners, and the blocking member 52 is used to contact and engage with the charging panel 91 of an external device.

[0186] 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 external devices for charging. A power transmission cable 61 is electrically connected to the charging plug-in assembly 30 to supply power to it. The power transmission cable 61 is supported by the casters of the first support assembly 62 on the walking surface and is further 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.

[0187] 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 guide rail and a slider. The second moving module 32 is movably mounted on the first moving module 31 along a second direction F2 via a 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 guide rail and a slider. The tilting module 34 is located between the third moving module 33 and the plugging module 35, and the tilting module 34 can adjust the angle of the plugging module 35.

[0188] When charging of an external device is required, the external device can be placed on the seating frame 20 using a hoisting device and guided by the guide assembly 21, so that the charging panel 91 of the external device and the interface 512 of the protective cover 50 are aligned as much as possible. The moving platform 40 moves closer to the external device along the moving guide rail 11 of the charging base 10 in the first direction F1, and drives the protective cover 50 and the charging plug-in assembly 30 closer to the external device until the second position positioning structure 56 comes into contact with the external device, at which point the moving platform 40 is in the second position, completing the initial positioning. At this time, the shielding member 52 of the protective cover 50 contacts and engages with the outer wall of the external device, the moving platform 40 stops moving, and the protective curtain... 55. Open the interface 512; the charging plug assembly 30 is close to the external device, and the accuracy of the 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, D vision feature hole positioning, etc., with the help of the identification component; according to the identification result, the charging plug 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 of 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 external device 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 panel 91 corresponding to another interface 512. By readjusting the relative position and angle, the first moving module 31 moves closer to the external device along the first direction F1 to connect the charging connector 351 to the charging port of the charging panel 91 for charging.

[0189] After charging is complete, the charging connector 351 is separated from the charging port by moving the first moving module 31 away from the external device in the first direction F1. The protective cover 50 is separated from the external device by moving the moving platform 40 away from the external device in the first direction F1. The protective curtain 55 covers and seals the interface 512. At this time, the external device can be transferred by hoisting.

[0190] In the above embodiments, the mobile platform 40 moves along the charging base 10 to achieve initial engagement and positioning of the charging plug-in assembly 30 and the protective cover 50 relative to the external equipment, providing conditions for improving the accuracy of subsequent relative position and relative angle recognition. The charging plug-in assembly 30 can actively adjust its charging posture with multiple degrees of freedom, enabling dual-circuit automatic plug-in charging. The charging connector 351 is highly aligned with the charging port of the charging panel 91, resulting in a high success rate of plugging and unplugging. The guide post of the plug-in module 35 and the pin of the charging port experience less wear, leading to a longer equipment lifespan and more stable and reliable performance. The modular design, with the seating frame 20 as one module and the charging device 2 as another, allows for quick connection of these two modules on-site using fasteners, eliminating the need for on-site alignment, facilitating installation, rapid deployment, reducing the construction cycle, and enabling rapid operation. The shielding component 52 of the protective cover 50 first engages with the external equipment, and then the protective curtain 55 opens the interface 512 before the charging connector 351 extends to engage with the charging port of the charging panel 91. This provides good protection, eliminating the risk of leakage and short circuits, physically isolating the device from rain and snow, and ensuring safe and reliable outdoor use. The identification component uses laser ranging to measure the distance and angle of the charging panel 91 area of ​​the external device. The charging device 2 aligns the connector panel with the charging connector 351 with the charging panel 91, and then uses D-image acquisition to locate the feature hole position, achieving high positioning accuracy. The secondary tapered guide post on the insertion 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 accuracy and a high success rate.

[0191] 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.
