Description

Technical Field

[0001] This application relates to the field of batteries, specifically to a charging system. Background Technology

[0002] After a ship with a depleted battery docks, the dock's tower cranes lift the power supply from the electric ship onto a container truck at the shore and transport it to a battery swapping station for charging. The charging process at the battery swapping station is all done manually, which is time-consuming, inefficient, and has low reliability. Utility Model Content

[0003] In view of the above problems, this application provides a charging system that can improve the low reliability of charging external devices.

[0004] This application provides a charging system, including: a charging base with a charging plug assembly on it; and a seating frame, which is disposed at one end of the charging base and connected to it. The seating frame is used to place an external device, and the charging plug assembly is movably coupled with the external device to charge the external device.

[0005] In the technical solution of this application embodiment, under the action of the charging base and the mounting bracket, there is no need for manual secondary alignment. While saving labor costs, it not only reduces the difficulty of placing external devices, but also improves the placement accuracy of external devices. It is convenient for external devices to cooperate with the charging plug assembly on the charging base for charging. This can reduce the wear problem caused by additional lateral forces on the charging point, and also reduce the probability of poor contact. The mounting bracket can also protect external devices, extend the service life of external devices, and improve the charging reliability of the entire charging system.

[0006] In some embodiments, the seating stand and the charging base are arranged along the length of the external device.

[0007] In the above technical solution, the seating frame and charging base are arranged along the length of the external device. This not only facilitates the external device and the charging assembly, but also avoids lateral expansion, reduces the footprint of the entire system in the width direction, and is suitable for narrow spaces.

[0008] In some embodiments, the charging base and the mounting frame are fixedly connected. In the above technical solution, by fixing the charging base and the mounting frame together, the stability of the entire charging system is improved, facilitating the charging of external devices with the charging plug-in assembly on the charging base. Furthermore, the mounting frame and the charging base can be manufactured separately and then fixedly connected on-site, simplifying the manufacturing process and improving assembly efficiency.

[0009] In some embodiments, a positioning part and a connecting part are provided between the charging base and the seating frame. The two are positioned by the positioning part and fixedly connected by the connecting part. In the above technical solution, the relative positions of the charging base and the seating frame can be determined, which facilitates further fixed connection between the charging base and the seating frame, improves assembly efficiency, and improves the fitting accuracy between external devices and the charging plug-in assembly.

[0010] In some embodiments, the charging base has a mounting protrusion at one end near the seating frame, and the seating frame has two guide structures at one end near the charging base. The two guide structures are spaced apart and define a positioning groove between them, and the mounting protrusion is adapted to extend into the positioning groove. In the above technical solution, the relative positions of the charging base and the seating frame can be determined, which facilitates further fixed connection between the charging base and the seating frame, improves assembly efficiency, and also improves the fitting accuracy between the external device and the charging plug-in assembly.

[0011] In some embodiments, the charging base includes a charging frame, the mounting protrusion is disposed on a first side beam of the charging frame, and the first side beam is provided with a first limiting hole. The guide structure is provided with a second limiting hole. The charging base and the seating frame are connected by fasteners passing through the first limiting hole and the second limiting hole. In the above technical solution, by using fasteners passing through the first and second limiting holes, the guide structure and the first side beam are fixedly connected, realizing the fixed connection between the seating frame and the charging base, which improves the stability of the entire charging system, facilitates the charging of external devices with the charging plug-in assembly on the charging base, and the seating frame and the charging base can be manufactured separately and then fixedly connected on site, simplifying the manufacturing process. The fastener connection method allows for quick connection on site. The cooperation of the mounting protrusion and the positioning groove eliminates the need for a complex alignment process on site, facilitating installation and improving assembly efficiency.

[0012] In some embodiments, the charging frame further includes two second side beams, which are arranged opposite to and connected to the first side beam at both ends. A portion of the second side beam is close to the seating frame relative to the first side beam, and the end of the second side beam abuts against the outer periphery of the seating frame. In the above technical solution, the cooperation between the second side beams and the seating frame can both position the charging base and the seating frame during assembly and improve the stability of the charging base and the seating frame after connection, thereby improving the reliability of the entire charging system.

[0013] In some embodiments, the seating frame includes a support body with a support portion for supporting the external device. In this solution, the weight of the external device can be transferred to the support body via the support portion, reducing the probability of damage to the support body. The support portion can be detached and installed from the support body, allowing for replacement even if damaged, thus reducing maintenance costs.

[0014] In some embodiments, the support body further includes multiple buffer pads, which are arranged circumferentially around the support body. The buffer pads are spaced apart from the support portion, and their height is greater than that of the support portion. In the above technical solution, the buffer pads compress and absorb impact kinetic energy, thus buffering external equipment. This prevents damage to the external equipment and also prevents excessive impact damage to the support portion or affecting its service life. After the buffer pads are compressed, the external equipment contacts the rigid support surface, locking its position.

[0015] In some embodiments, the seating frame further includes a guide structure. The guide structure has an outer periphery of the support body, and its upper part has a guide surface that extends obliquely downwards towards the support body. In the above technical solution, by providing a guide structure with a guide surface, the placement of external devices can be guided, further reducing the difficulty of placing external devices, improving the efficiency of external device placement, and simultaneously improving the placement accuracy of external devices, facilitating the connection between external devices and the charging plug-in assembly.

[0016] In some embodiments, the seating frame further includes a trigger mechanism disposed on the support body. The trigger mechanism includes a trigger switch and a trigger element. The trigger switch is fixed on the support body to determine whether the external device is installed correctly. The trigger element is movable between a first position and a second position. When the external device is placed on the support body, it can drive the trigger element to move from the first position to the second position, so that the trigger element cooperates with the trigger switch. In the above technical solution, by setting a trigger mechanism, a safety protection function can be achieved. The trigger mechanism sends a signal to the charging system indicating whether the external device is installed correctly, so that the charging system can charge the external device after confirming that it is installed correctly, avoiding risks such as charging failure caused by loose connection or floating.

[0017] In some embodiments, the charging system is provided with at least two triggering mechanisms, which are arranged symmetrically around the center of the bracket body. In the above technical solution, by providing multiple triggering mechanisms, the accuracy of determining the correct installation position of external devices can be improved. Furthermore, if one side cannot be properly positioned, the position of the external device can be adjusted, or uneven compression of the buffer pad or deformation of the bracket body can be detected in advance, thereby enabling timely maintenance and improving reliability.

[0018] In some embodiments, the charging plug-in assembly includes a plug-in module having multiple charging connectors for corresponding connections to multiple charging ports on the external device. In the above technical solution, the cooperation of the charging connectors and charging ports enables rapid charging of the external device, making charging convenient.

[0019] In some embodiments, the plug-in module is provided with a connector panel, and the plurality of charging connectors are all disposed on the same connector panel. In the above technical solution, the plurality of charging connectors are arranged on a connector panel, which facilitates the synchronous movement of the plurality of charging connectors through the movement of the connector panel, thereby improving the cooperation efficiency between the plug-in module and the external device before charging.

[0020] In some embodiments, the plug-in module is provided with positioning pins or positioning holes to engage with the corresponding positioning holes or positioning pins on the external device. In the above technical solution, when the external device moves towards the charging plug-in assembly, the positioning pins first insert into the corresponding positioning holes, converging the positional deviation of the external device relative to the charging plug-in assembly. This ensures that the subsequent charging connector completes insertion in a predetermined alignment state, achieving zero lateral force connection, reducing the probability of charging connector damage, improving charging reliability, and extending the service life of the charging plug-in assembly.

[0021] In some embodiments, the charging plug-in assembly includes one module that is movable relative to the external device for engaging with any one of a plurality of charging panels on the plurality of external devices. In the above technical solution, by employing a single plug-in module of a charging plug-in assembly to alternately plug into multiple charging panels, charging of multiple charging circuits can be achieved without increasing the number of plug-in modules, thus reducing the overall size of the charging plug-in assembly and lowering manufacturing costs.

[0022] In some embodiments, the charging plug-in assembly includes a moving module and a tilting module. The moving module is disposed on the charging base and is connected to the tilting module to drive the tilting module to move. The tilting module is connected to the plug-in module to drive the plug-in module to tilt. In the above technical solution, by driving the plug-in module to move through the moving module and the tilting module, high-precision plug-in charging is achieved without the need for manual alignment and switching of the charging gun, thus saving labor costs and improving charging efficiency.

[0023] In some embodiments, the external device includes multiple charging panels, and the charging plug-in assembly includes a moving module and multiple oscillating modules. The moving module is connected to the multiple oscillating modules to drive the movement of the multiple oscillating modules. Multiple plug-in modules are included, and the multiple oscillating modules are connected one-to-one with the multiple plug-in modules. The multiple plug-in modules are adapted to cooperate with the multiple charging panels under the drive of the moving module and the oscillating modules. In the above technical solution, by driving the movement of multiple plug-in modules through the moving module and the multiple oscillating modules, charging efficiency can be further improved while achieving high-precision plug-in charging.

[0024] In some embodiments, the external device includes multiple charging panels, and the charging plug-in assembly includes multiple components, with each of the multiple charging plug-in assemblies corresponding one-to-one with a single charging panel. This technical solution improves the docking accuracy between each plug-in module and the charging panel, thereby increasing the plug-in success rate and charging success rate.

[0025] In some embodiments, the charging plug-in assembly includes a plug-in module with a charging connector for plugging into a charging port on an external device. The moving module includes a first moving module movably mounted on the charging base along a first direction. The plug-in module is mounted on the first moving module and moves relative to the charging base along the first direction with the first moving module. The charging connector plugs into the charging port along the first direction, where the first direction is the length direction of the external device. In this technical solution, the first moving module enables the plug-in module to move along the first direction with high precision, facilitating the plug-in connection between the charging connector and the charging panel of the external device. This results in high plug-in accuracy and a high charging success rate. Furthermore, it eliminates the need for manual alignment and switching of the charging gun, saving labor costs and improving charging efficiency.

[0026] In some embodiments, the moving 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 charging base along the first and second directions with the first and second moving modules, respectively. The second direction is the width direction of the external device. In the above technical solution, the first and second moving modules enable the plug-in module to move along the first and second directions with high precision, facilitating the connection between the charging connector and the charging panel of the external device. This ensures high plug-in accuracy and a high charging success rate. Furthermore, it eliminates the need for manual alignment and switching of the charging gun, saving labor costs and improving charging efficiency.

[0027] In some embodiments, the external device includes a plurality of charging panels arranged sequentially along the second direction at one end of the external device facing the charging plug assembly. The charging plug assembly includes one assembly that is movable relative to the external device along the second direction to engage with any one of the plurality of charging panels.

[0028] In some embodiments, the moving module further includes a third moving module, which is movably mounted on the second moving module along a third direction. A plug-in module is disposed on the third moving module, and the plug-in module is movable relative to the charging base along the first, second, and third directions, where the third direction is the height direction of the external device. In the above technical solution, the first, second, and third moving modules enable the plug-in module to move along the first, second, and third directions with high precision, facilitating the connection between the charging connector and the charging panel of the external device. This ensures high plug-in accuracy and a high charging success rate. Furthermore, it eliminates the need for manual alignment and switching of the charging gun, saving labor costs and improving charging efficiency.

[0029] In some embodiments, a mobile platform is further included, which is mounted on the charging base and movable relative to the charging base in a first direction, the charging plug-in assembly is mounted on the mobile platform, and the mobile platform is movable relative to the seating frame to move the mobile platform closer to and away from the seating frame.

[0030] In the above technical solution, 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. This facilitates more precise positioning and cooperation between the charging plug assembly and the external device, reduces docking difficulty, reduces the risk of plugging failure, improves charging efficiency, and reduces the risk of damage to the docking structure between the charging plug assembly and the external device.

[0031] In some embodiments, the mobile station 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 station being located at the first position when the external device is not present at the seating position.

[0032] 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.

[0033] In some embodiments, the charging device further includes a protective cover mounted on the mobile platform and having a receiving space, the charging plug assembly being located within the receiving space, the protective cover having a mating interface, and the movable module being able to drive the charging connector to extend from the mating interface to engage with a charging port on the external device.

[0034] 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.

[0035] In some embodiments, a shielding member is provided at the interface, the shielding member extending along the edge of the interface and used to contact and engage with the outer wall of the external device.

[0036] 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.

[0037] The above description is only an overview of the technical solution of this application. In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, rather than to describe a specific order or hierarchy.

[0042] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0043] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0045] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0046] In this application, "multiple" means two or more (including two).

[0047] In related technologies, external devices are usually placed directly on the ground or on a simple roller tray, and then manually pushed and pulled to connect with the charging base. Since there is no rigid positioning reference, manual re-alignment is required after each placement, which takes a long time and makes it difficult to implement automated battery swapping. At the same time, due to the heavy weight of the external devices, the random insertion and removal path when the ground is uneven or the rollers are misaligned causes the charging interface to be subjected to additional lateral forces, making the charging connector prone to wear.

[0048] Therefore, this application proposes a charging system, including: a charging base, on which a charging plug assembly is provided; a seating frame, one end of which is disposed, for placing an external device, and the charging plug assembly is movably coupled with the external device to charge the external device.

[0049] According to the charging system of the present application embodiment, the charging base and the mounting bracket reduce the difficulty of placing external devices and improve the placement accuracy of external devices. This facilitates the external devices to cooperate with the charging plug assembly on the charging base for charging. It can reduce wear caused by additional lateral forces on the charging point and reduce the probability of poor contact. The mounting bracket can also protect the external devices, extend their service life, and improve the reliability of the entire charging system.

[0050] like Figures 1-19 As shown in the embodiment of this application, the charging system 1 can be used to charge the external device 90 of the electrical equipment. The external device 90 can be a box-type power supply, which is an integrated and modular power device that integrates power modules, control systems, protection units, fire protection facilities, etc., into a protective box. It has the characteristics of flexible deployment, strong environmental adaptability, and safety and reliability. The electrical equipment can be, but is not limited to, box-type substations, ships, outdoor work equipment, laboratories, mobile emergency power supply equipment, communication base stations, etc.

[0051] The charging system 1 according to an embodiment of this application is described below with reference to the accompanying drawings.

[0052] Reference Figures 1-6 As shown, the charging system 1 according to an embodiment of this application includes: a charging base 10 and a seating frame 20. The charging base 10 is provided with a charging plug assembly 30. The seating frame 20 is disposed at one end of the charging base 10 and is used to place an external device 90. The charging plug assembly 30 is movably engaged with the external device 90 to charge the external device 90.

[0053] The charging base 10 supports the charging plug assembly 30. The charging base 10 can be partially buried underground. The charging plug assembly 30 can be directly installed on the charging base 10 or indirectly installed on the charging base 10 through other components. The charging plug assembly 30 can be movable relative to the charging base 10 or it can be fixed.

[0054] like Figure 6 As shown, the charging base 10 includes a charging frame 12 and two tracks 11 disposed on the charging frame 12. The charging frame 12 includes two first side beams 121 opposite each other along a first direction F1 and two second side beams 122 opposite each other along a second direction F2. Adjacent first side beams 121 are connected to second side beams 122, and the two tracks 11 are respectively disposed on the two second side beams 122.

[0055] The charging base 10 also includes a movable platform 40 and a protective cover 50. The movable platform 40 is movably mounted on the track 11 of the charging base 10 along the first direction F1 via movable wheels 41. The protective cover 50 is mounted on the movable platform 40 and can enclose the charging plug assembly 30 on the movable platform 40 to achieve a rainproof effect.

[0056] The charging plug assembly 30 is used to connect to an external device 90 to charge the external device 90 via the charging plug assembly 30.

[0057] The charging and plugging assembly 30 may include 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 is provided with a charging connector 351. The first moving module 31 is movably disposed on the moving platform 40 and then on the charging base 10 along a first direction F1. The second moving module 32 is movably mounted on the first moving module 31 along a second direction F2. The third moving module 33 is movably mounted on the second moving module 32 along a third direction F3. The tilting module 34 is disposed between the third moving module 33 and the plugging module 35, and the tilting module 34 can drive the plugging module 35 to rotate relative to the third moving module 33. The position and angle of the plugging module 35 can be adjusted by the tilting module 34. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other.

[0058] Using the above-mentioned charging plug-in assembly 30, during the charging process, the charging connector 351 is inserted into or pulled out of the charging port 911 of the external device 90 to establish or disconnect the charging connection. During the charging process, it has mechanical connection, electrical on / off, communication interaction and safety protection mechanisms. At the same time, with the help of the moving module and the swaying module 34, automated charging can be realized, replacing manual connection and disconnection operations, improving charging efficiency, reducing manual intervention and realizing unmanned operation.

[0059] The mounting bracket 20 provides support for the external device 90. The mounting bracket 20 can be partially pre-buried underground to fix the mounting bracket 20. After the external device 90 is placed on the mounting bracket 20, the external device 90 can be opposite the charging plug assembly 30 along the first direction F1. The mounting bracket 20 can position the external device 90, reduce the probability of the external device 90 tilting and shaking, and protect the external device 90 from physical damage to the ground, thus extending its service life. The external device 90 is placed on the mounting bracket 20, which can also improve the contact alignment accuracy of the charging connector 351 and reduce the probability of poor contact. In addition, a monitoring module can be integrated on the mounting bracket 20 for automatic power on and off.

[0060] The seating frame 20 is provided with a guide structure 22, which has a guide surface 2221 that extends inclinedly from top to bottom into the seating frame 20. During the process of placing the external device 90 on the seating frame 20, the guide surface 2221 guides the external device 90, which helps to reduce the difficulty of placing the external device 90 and improve the placement accuracy of the external device 90.

[0061] According to the charging system 1 of this application embodiment, under the action of the charging base 10 and the mounting bracket 20, no manual secondary alignment is required. While saving labor costs, it not only reduces the difficulty of placing the external device 90, but also improves the placement accuracy of the external device 90. This facilitates the external device 90 to cooperate with the charging plug-in assembly 30 on the charging base 10 for charging. It can reduce the wear problem caused by the additional lateral force on the charging point, and also reduce the probability of poor contact. The mounting bracket 20 can also protect the external device 90, which can extend the service life of the external device 90 and improve the charging reliability of the entire charging system 1.

[0062] like Figure 1 As shown, in some embodiments, the seating stand 20 and the charging base 10 are arranged along the length of the external device 90.

[0063] like Figure 1 As shown, the external device 90 has a cuboid structure, with its length direction being the direction of its maximum dimension. The length direction of the external device 90 is the first direction F1. The charging base 10 is arranged on one side of the seating frame 20 in the first direction F1. The charging panel 91 of the external device 90 can be arranged at one end of the external device 90 in the length direction. The overall size of the docking end of the external device 90 and the charging plug assembly 30 is small, and the probability of misalignment is small, which can improve the success rate of plugging. The size or range of motion of the charging plug assembly 30 is correspondingly reduced, which can reduce the size of the charging base 10 in the second direction F2. The width of the charging base 10 in the second direction F2 can be approximately the same as the width of the seating frame 20. Thus, while achieving docking charging, there is no need to increase the space occupied by the charging system 1 in the second direction F2.

[0064] In the above technical solution, the seating frame 20 and the charging base 10 are arranged along the length of the external device 90. This not only facilitates the external device 90 and the charging plug-in assembly 30, but also avoids lateral expansion, reduces the footprint of the entire system in the width direction, and is suitable for narrow spaces.

[0065] like Figures 6-8 As shown, in some embodiments, the charging base 10 and the seating stand 20 are fixedly connected.

[0066] The seating frame 20 is fixedly connected to the charging base 10. The seating frame 20 and the charging base 10 can be manufactured in modules and then connected to the charging base 10. The two can be detachably connected by fasteners such as bolts or by welding, thereby improving the stability of the overall structure.

[0067] In the above technical solution, by fixing the charging base 10 and the mounting frame 20 together, the stability of the entire charging system 1 is improved, and it is convenient for the external device 90 to cooperate with the charging plug-in assembly 30 on the charging base 10 for charging. Furthermore, the mounting frame 20 and the charging base 10 can be manufactured separately and then fixedly connected on site, which simplifies the manufacturing process and improves assembly efficiency.

[0068] In some embodiments, a positioning part and a connecting part are provided between the charging base 10 and the seating frame 20. The two are positioned by the positioning part and fixedly connected by the connecting part.

[0069] like Figure 7 and Figure 8 As shown, in some embodiments, the positioning part includes a positioning protrusion 1201 and a positioning groove 2202. Specifically, the end of the charging base 10 near the seat frame 20 has a mounting protrusion 1201, and the end of the seat frame 20 near the charging base 10 has two guide structures 22. The two guide structures 22 are arranged at intervals, and a positioning groove 2202 is defined between the two guide structures 22. The mounting protrusion 1201 is adapted to extend into the positioning groove 2202.

[0070] like Figures 6-8 As shown, in the first direction F1, a mounting protrusion 1201 is provided at one end of the charging base 10. The mounting protrusion 1201 can extend into the positioning groove 2202 of the seating frame 20 to achieve pre-positioning of the charging base 10 and the seating frame 20, reduce the probability of misalignment between the charging base 10 and the seating frame 20, and facilitate the fixed connection of the charging base 10 and the seating frame 20 at the usage site, thereby improving organizational efficiency.

[0071] like Figures 6-8 As shown, the width of the mounting protrusion 1201 in the second direction F2 can be the same as or slightly smaller than the width of the positioning groove 2202 in the second direction F2, to facilitate the mating and insertion of the two. In some examples, the connecting part may include a first mating part and a second mating part. Specifically, the end of the charging base 10 near the seat frame 20 has a first mating part, and the end of the seat frame 20 near the charging base 10 has a second mating part, and the first mating part and the second mating part are fixedly connected.

[0072] The first mating part and the second mating part are fixedly connected, so that the relative position of the seat 20 and the charging base 10 can be locked, thereby reducing the probability of the relative position of the charging base 10 and the seat 20 changing after the external device 90 is placed on the seat. At the same time, the impact force generated by the placement of the external device 90 on the seat 20 can be absorbed by the seat 20 and the charging base 10 as a whole. The seat 20 and the charging base 10 have a common vibration mode, avoiding fretting wear. In addition, the unchanged relative position of the seat 20 and the charging base 10 can also improve the mating accuracy between the external device 90 and the charging plug assembly 30.

[0073] In the above technical solution, the relative positions of the charging base 10 and the mounting bracket 20 can be determined, which facilitates the further fixed connection of the charging base 10 and the mounting bracket 20, improves assembly efficiency, and also improves the fitting accuracy between the external device 90 and the charging plug-in assembly 30.

[0074] like Figure 6 As shown, in some embodiments, the charging base 10 includes a charging frame 12, a mounting protrusion 1201 is provided on the first side beam 121 of the charging frame 12, and the first side beam 121 is provided with a first limiting hole 1211, the guide structure 22 is provided with a second limiting hole 2201, and the charging base 10 and the seating frame 20 are connected by fasteners passing through the first limiting hole 1211 and the second limiting hole 2201.

[0075] like Figure 6 As shown, the first side beam 121 forms a first mating part, and the guide structure 22 forms a second mating part 202. The first side beam 121 at one end of the charging frame 12 in the first direction F1 is provided with a first limiting hole 1211, and the guide structure 22 at one end of the seating frame 20 in the first direction F1 is provided with a second limiting hole 2201. The first side beam 121 is provided with an outwardly protruding mounting protrusion 1201. After the mounting protrusion 1201 extends into the positioning groove 2202, the first side beam 121 can move to a position that abuts against the guide structure 22, and the positions of the first limiting hole 1211 and the second limiting hole 2201 correspond, so that fasteners can be inserted for connection.

[0076] In the above technical solution, the guide structure 22 and the first side beam 121 are fixedly connected by fasteners passing through the first limiting hole 1211 and the second limiting hole 2201, thereby realizing the fixed connection between the seat frame 20 and the charging base 10. This improves the stability of the entire charging system 1 and facilitates the charging of the external device 90 with the charging plug-in assembly 30 on the charging base 10. Furthermore, the seat frame 20 and the charging base 10 can be manufactured separately and then fixedly connected on site, simplifying the manufacturing process. The fastener connection method allows for quick connection on site. With the cooperation of the mounting protrusion 1201 and the positioning groove 2202, there is no need for a complex alignment process on site, which facilitates installation and improves assembly efficiency.

[0077] like Figure 6 As shown, in some embodiments, the charging frame 12 further includes two second side beams 122, which are arranged opposite to the two ends of the first side beam 121 and connected to the first side beam 121. A portion of the second side beam 122 is close to the seat frame 20 relative to the first side beam 121, and the end of the second side beam 122 abuts against the outer periphery of the seat frame 20.

[0078] like Figure 6 As shown, the entire charging frame 12 is formed by two second side beams 122 and multiple first side beams 121, ensuring the stability of the charging frame 12. In the first direction F1, one end of the second side beam 122 abuts against the outer periphery of the seat frame 20. The second side beam 122 can play an auxiliary positioning role. The mounting protrusion 1201 and the first limiting hole 1211 are located in the middle of the first side beam 121, and the second side beam 122 is located at the end of the first side beam 121. With the joint cooperation of the mounting protrusion 1201, the first side beam 121 and the second side beam 122, in the second direction F2, the contact surface between the charging base 10 and the seat frame 20 is increased, improving the reliability of the connection between the charging base 10 and the seat frame 20.

[0079] In the above technical solution, the cooperation between the second side beam 122 and the seat frame 20 can not only play a positioning role in the assembly of the charging base 10 and the seat frame 20, but also improve the stability of the charging base 10 and the seat frame 20 after connection, thereby improving the reliability of the entire charging system 1.

[0080] like Figure 3 and Figure 4 As shown, in some embodiments, the seating frame 20 includes a support body 21, on which a support portion 2101 is provided, which is used to support an external device 90.

[0081] The support part 2101 is located on the upper surface of the bracket body 21. The support part 2101 can be multiple small support structures or a large integral support structure. The external device 90 is supported on the support part 2101. Thus, the weight of the external device 90 can be transferred to the bracket body 21 through the support part 2101, reducing the probability of damage to the bracket body 21. The support part 2101 can be disassembled and installed from the bracket body 21, so that it can be replaced even if it is damaged, reducing maintenance costs.

[0082] like Figure 3 As shown, in some embodiments, the support body 21 also has a plurality of buffer pads 213, which are arranged at intervals along the circumference of the support body 21. The buffer pads 213 are arranged at intervals with the support portion 2101, and the height of the buffer pads 213 is higher than the height of the support portion 2101.

[0083] like Figure 3 As shown, multiple buffer pads 213 are provided on the bracket body 21. The buffer pads 213 can be made of elastic compressible materials such as polyurethane. The buffer pads 213 and the support part 2101 are located on the upper surface of the bracket body 21. In the free state, the height of the buffer pads 213 is higher than the height of the support part 2101. When the external device 90 is placed, the external device 90 will first contact the buffer pads 213 after falling. Thus, the buffer pads 213 are compressed and absorb the impact kinetic energy, which can buffer the external device 90. This can prevent the external device 90 from being damaged and prevent the support part 2101 from being damaged by excessive impact or affecting its service life. After the buffer pads 213 are pressed to be flush with the support part 2101 (or slightly lower than the upper surface of the support part 2101), the external device 90 contacts the rigid support surface and completes the position locking.

[0084] Multiple buffer pads 213 are evenly distributed along the circumference of the bracket body 21, which can increase the contact area with the external equipment 90, reduce the probability of the external equipment 90 swaying, and avoid the probability of the external equipment 90 being scratched and damaged by the support part 2101.

[0085] The buffer pad 213 can be installed on the bracket body 21 by fasteners, which can be bolts. In this case, the upper part of the buffer pad 213 can be provided with a downward recessed groove, and the end of the bolt is accommodated in the groove to prevent the fastener from protruding from the buffer pad 213 and scratching the external equipment 90.

[0086] like Figures 3-5 As shown, in some embodiments, the seating frame 20 further includes a guide structure 22, which is disposed on the outer periphery of the support body 21. The upper part of the guide structure 22 has a guide surface 2221, which extends obliquely from top to bottom toward the support body 21.

[0087] There can be multiple guide structures 22, which are arranged at intervals on the outer periphery of the support body 21; the guide structure 22 can also be a large integral guide structure 22, for example, forming a ring, with a large integral guide surface 2221 on its upper surface, the guide surface 2221 forming a ring, and its upper surface can also have multiple guide surfaces 2221 arranged at intervals.

[0088] The guide structure 22 can guide the external device 90 through the guide surface 2221 during the placement of the external device 90 on the seating frame 20. Even if there is an initial positional deviation between the external device 90 and the support body 21, the external device 90 can be automatically aligned by the sliding correction of the guide surface 2221, which significantly reduces the difficulty of placement, improves the seating efficiency, improves the placement accuracy of the external device 90, reduces the probability of misalignment between the external device 90 and the charging plug-in assembly 30, and improves the success rate of plugging in.

[0089] In the above technical solution, by setting a guide structure 22 with a guide surface 2221, the placement of the external device 90 can be guided, further reducing the difficulty of placing the external device 90, improving the placement efficiency of the external device 90, and further improving the placement accuracy of the external device 90, making it easier for the external device 90 to be plugged into the charging plug assembly 30.

[0090] like Figure 4 , Figures 9-11 As shown, in some embodiments, the seating frame 20 further includes a trigger mechanism 23, which is disposed on the support body 21. The trigger mechanism 23 includes a trigger switch 231 and a trigger element 232. The trigger switch 231 is fixed on the support body 21 to determine whether the external device 90 is installed in place. The trigger element 232 is movable between a first position and a second position. When the external device 90 is placed on the support body 21, it can drive the trigger element 232 to move from the first position to the second position, so that the trigger element 232 cooperates with the trigger switch 231.

[0091] like Figure 4 As shown, the seating frame 20 is provided with two triggering mechanisms 23. Of course, one or more can also be provided. Each triggering mechanism 23 includes a trigger switch 231 and a trigger element 232. The trigger switch 231 can be a contact switch or a non-contact switch. For example, the trigger switch 231 can be a micro switch, photoelectric switch, Hall switch, pressure switch, proximity switch, etc. The trigger element 232 can be driven when the external device 90 is seated. When the external device 90 is not placed on the seating frame 20, the trigger element 232 is in the first position. When the external device 90 is seated, the trigger element 232 can be moved to the second position, and the trigger element 232 only cooperates with the trigger switch 231 in the second position, thereby closing the trigger switch 231.

[0092] The trigger switch 231 can be electrically connected to the power supply of the entire charging system 1, so that when the trigger switch 231 is closed, the external device 90 is completed and the structure on the charging base 10 can be activated, or the charging connector 351 of the charging plug assembly 30 can be energized so that the charging connector 351 can charge the external device 90.

[0093] As long as the external device 90 does not fall to the bottom, the buffer pad 213 is not flattened, and the external device 90 is not in contact with the support 2101, the trigger 232 cannot move to the second position, and the trigger switch 231 remains open, thereby preventing risks such as charging failure caused by poor connection or floating.

[0094] In the above technical solution, by setting a trigger mechanism 23, a safety protection function can be achieved. The trigger mechanism 23 sends a signal to the charging system 1 to indicate whether the external device 90 is installed in place, so that the charging system 1 can charge the external device 90 after confirming that it is installed in place, thereby avoiding risks such as charging failure caused by loose connection or floating discharge.

[0095] like Figure 4 As shown, in some embodiments, the seating frame 20 is provided with at least two triggering mechanisms 23, and the at least two triggering mechanisms 23 are arranged in a centrally symmetrical manner along the center of the support body 21.

[0096] like Figure 4 As shown, two triggering mechanisms 23 are arranged on the mounting frame 20. The action of either triggering mechanism 23 does not mean that the device is in place. Both triggering mechanisms 23 must close simultaneously to determine that the external device 90 is in place. The two triggering mechanisms 23 are symmetrical about the center of the bracket body 20 and are roughly arranged near the diagonal of the bracket body 21, thereby improving the accuracy of the judgment.

[0097] In the above technical solution, by setting multiple triggering mechanisms 23, the accuracy of judging the installation position of external equipment 90 can be improved. At the same time, when one side cannot be in place, the position of external equipment 90 can be adjusted, or uneven compression of buffer pad 213 or deformation of bracket body 21 can be detected in advance, so that timely maintenance can be carried out and the reliability of use can be improved.

[0098] like Figure 16 and Figure 17 As shown, in some embodiments, the charging plug-in assembly 30 includes a plug-in module 35, which has a plurality of charging connectors 351 for corresponding connection to a plurality of charging ports 911 on an external device 90.

[0099] External device 90 has at least one charging panel 91, and each charging panel 91 is provided with at least one charging port 911, such as Figure 16 and Figure 17 As shown, the external device 90 is provided with two charging panels 91. Each charging panel 91 has multiple charging ports 911. The plug-in module 35 of the charging plug-in assembly 30 can be one or multiple. Each plug-in module 35 has multiple charging connectors 351.

[0100] like Figure 13 As shown, the charging connector 351 is electrically connected to the cable 61, which can also be electrically connected to a charging station or other electrical storage device to charge the external device 90 via the cable 61 and the charging plug assembly 30.

[0101] For example, in some examples, when the external device 90 is charging, multiple charging connectors 351 engage with multiple charging ports 911. One end of a cable 61 is electrically connected to the charging connector 351, and the other end of the cable 61 can be electrically connected to the charging station, so that the power from the charging station can be transferred to the charging connector 351 and then to the external device 90 through the cable 61, thereby enabling power supply to the external device 90.

[0102] In the above technical solution, the plug-in module 35 and the charging panel 91 work together to achieve fast charging of the external device 90, making charging convenient.

[0103] like Figure 14 As shown, in some embodiments, the plug-in module 35 is provided with a connector panel 354, and multiple charging connectors 351 are all disposed on the same connector panel 354.

[0104] like Figure 14 As shown, the connector panel 354 is provided with multiple charging connectors 351. The connector panel 354 moves toward the external device 90, which drives the multiple charging connectors 351 to move, so that the multiple charging connectors 351 can cooperate with multiple charging ports 911 at the same time, thereby improving the cooperation efficiency.

[0105] In the above technical solution, multiple charging connectors 351 are arranged on a connector panel 354, which facilitates the synchronous movement of multiple charging connectors 351 through the movement of the connector panel 354, thereby improving the cooperation efficiency between the charging pre-plug module 35 and the external device 90.

[0106] like Figures 14-17 As shown, in some embodiments, one of the plug-in modules 35 is provided with a positioning pin 352 or a positioning hole 912 to be plugged into and engaged with a positioning hole 912 or a positioning pin 352 adapted on the external device 90.

[0107] like Figure 14 and Figure 17 As shown, the charging panel 91 is provided with multiple positioning holes 912, and the plug-in module 35 is provided with multiple positioning pins 352. The positioning pins 352 are inserted and engaged with the positioning holes 912, thereby positioning the charging panel 91 and the plug-in module 35, thus achieving synchronous positioning of the charging port 911, ensuring that the charging connector 351 and the charging port 911 are in the same position, and then the charging connector 351 and the charging port 911 are plugged in, avoiding wear of the charging connector 351 and improving the service life of the charging plug-in assembly 30.

[0108] Of course, the positioning pin 352 can also be set on the charging panel 91, and the positioning hole 912 can be set on the plug-in module 35, or both the charging panel 91 and the plug-in module 35 can be equipped with positioning pins 352 and positioning holes 912. By cooperating with multiple positioning pins 352 and positioning holes 912, the positioning accuracy can be improved.

[0109] In the above technical solution, when the external device 90 moves toward the charging plug assembly 30, the positioning pin 352 first inserts into the corresponding positioning hole 912 to converge the positional deviation of the external device 90 relative to the charging plug assembly 30, so that the subsequent charging connector 351 completes the insertion in the predetermined alignment state, thereby achieving zero lateral force docking, reducing the probability of damage to the charging connector 351, improving the reliability of charging and the service life of the charging plug assembly 30.

[0110] like Figures 1-17 As shown, in some embodiments, the charging plug-in assembly 30 includes one that is movable relative to the external device 90 for engaging with any of a plurality of charging panels 91 on the external device 90.

[0111] like Figures 1-17 As shown, the charging system 1 includes a charging plug-in assembly 30, which has a plug-in module 35, such as Figure 1 As shown, the external device has two charging panels 91 on its end face, forming two charging circuits. The two charging panels 91 are respectively arranged on one end face of the external device 90, and the two charging panels 91 are arranged at intervals. The charging plug-in assembly 30 moves to the first charging panel 91 and plugs into it to realize the charging of the first charging circuit. After the first charging circuit is fully charged, the charging plug-in assembly 30 is unplugged and moved to the second charging panel 91 to realize the charging of the second charging circuit.

[0112] In the above technical solution, by using a plug-in module 35 of a charging plug-in assembly 30 to alternately plug into multiple charging panels 91, multiple charging circuits can be charged without increasing the number of plug-in modules 35, which helps to reduce the size of the entire charging plug-in assembly 30 and reduce manufacturing costs.

[0113] In some embodiments, the charging plug-in assembly 30 includes a moving module and a swaying module 34. The moving module is disposed on the charging base 10 and is connected to the swaying module 34 to drive the multiple swaying modules 34 to move. The swaying module 34 is connected to the plug-in module 35 to drive the plug-in module 35 to sway.

[0114] Specifically, the moving module can drive the yaw module 34 to move along the first direction F1, the second direction F2, and the third direction F3, thereby driving the plug-in module 35 to move along the first direction F1, the second direction F2, and the third direction F3. The yaw module 34 can drive the plug-in module 35 to yaw and rotate, thereby enabling the plug-in module 35 to correspond to the position of the charging panel 91. The charging connector 351 and the charging port 911 have high matching accuracy, enabling the plug-in module 35 to be accurately electrically connected to the corresponding charging panel 91, resulting in higher plug-in accuracy and a higher plug-in success rate.

[0115] The moving module can be a linear slider guide mechanism or a C-groove and bolt-type composite roller mechanism.

[0116] In the above technical solution, the plug-in module 35 is driven to move by the moving module and the swaying module. While achieving high-precision plug-in charging, it eliminates the need for manual adjustment of the charging gun for alignment and switching, thus saving labor costs and improving charging efficiency.

[0117] like Figure 18 As shown, in some embodiments, the external device 90 includes a plurality of charging panels 91, the charging plug-in assembly 30 includes a moving module and a plurality of oscillating modules 34, the moving module is connected to the plurality of oscillating modules 34 to drive the plurality of oscillating modules 34 to move, the plug-in module 35 includes a plurality of modules, the plurality of oscillating modules 34 are connected one-to-one with the plurality of plug-in modules 35, and the plurality of plug-in modules 35 are adapted to cooperate with the plurality of charging panels 91 under the drive of the moving module and the oscillating modules 34.

[0118] In other words, the moving module can drive multiple oscillating modules 34 to move simultaneously along the first direction F1 (front and back), the second direction F2 (left and right), and the third direction F3 (up and down). As a result, the multiple oscillating modules 34 can drive multiple plug-in modules 35 to oscillate and rotate, so that the multiple plug-in modules 35 can correspond to the positions of multiple charging panels 91, realize the charging of multiple charging circuits, and improve charging efficiency.

[0119] In the above technical solution, multiple plug-in modules 35 are driven to move by a moving module and multiple oscillating modules, which can further improve charging efficiency while achieving high-precision plug-in charging.

[0120] like Figure 19 As shown, in some embodiments, the external device 90 includes a plurality of charging panels 91, and the charging plug-in assembly 30 includes a plurality of charging panels 91, with each of the plurality of charging plug-in assemblies 30 corresponding to one of the plurality of charging panels 91.

[0121] Each charging plug-in assembly 30 includes a moving module, a swaying module 34, and a plug-in module 35. Multiple charging plug-in assemblies 30 are independent of each other and do not interfere with each other. This helps to improve the docking accuracy between each plug-in module 35 and the charging panel 91, and improve the plug-in success rate and charging success rate.

[0122] like Figure 13 As shown, in some embodiments, the charging plug-in assembly 30 includes a plug-in module 35, which is provided with a charging connector 351 for plugging into the charging port 911 on the external device 90; the charging plug-in assembly 30 includes a moving module, which includes a first moving module 31, which is movably disposed on the charging base 10 along a first direction F1; the plug-in module 35 is movable relative to the charging base 10 along the first direction F1 with the first moving module 31; the charging connector 351 is plugged into the charging port 911 along the first direction F1, where the first direction F1 is the length direction of the external device 90.

[0123] By setting the first moving module 31, the plug-in module 35 can move along the first direction F1, thereby cooperating with the charging panel 91 at one end of the external device 90 to charge the external device 90.

[0124] In the above technical solution, the first moving module 31 enables the plugging and unplugging module 35 to move along the first direction F1 with high precision, so that the charging connector 351 can be plugged into the charging panel 91 of the external device 90 with high plugging and unplugging precision and high charging success rate; at the same time, there is no need for manual removal of the charging gun for alignment and switching, which saves labor costs and improves charging efficiency.

[0125] like Figure 13 As shown, in some embodiments, the mobile module further includes a second mobile module 32, which is movably mounted on the first mobile module 31 along the second direction F2. The plug-in module 35 is disposed on the second mobile module 32, and the plug-in module 35 is movable relative to the charging base 10 along the first direction F1 and the second direction F2 with the first mobile module 31 and the second mobile module 32. The second direction F2 is the width direction of the external device 90.

[0126] By setting a second moving module 32 on the first moving module 31, the plug-in module 35 can move along both the first direction F1 and the second direction F2, thereby cooperating with the charging panel 91 at one end of the external device 90 to charge the external device 90. At the same time, it can move in the second direction F2 to improve the fitting accuracy and facilitate cooperation with multiple charging panels 91.

[0127] In the above technical solution, the first moving module 31 and the second moving module 32 enable the plug-in module 35 to move along the first direction F1 and the second direction F2 with high moving accuracy, so that the charging connector 351 can be plugged into the charging panel 91 of the external device 90 with high plug-in accuracy and high charging success rate; at the same time, there is no need for manual removal of the charging gun for charging alignment and switching, which saves labor costs and improves charging efficiency.

[0128] like Figure 16 As shown, in some embodiments, the external device 90 includes a plurality of charging panels 91 arranged sequentially along a second direction F2 at one end of the external device 90 facing the charging plug assembly 30. The charging plug assembly 30 includes one unit that is movable relative to the external device 90 along the second direction F2 to engage with any one of the plurality of charging panels 91.

[0129] like Figure 1 , Figure 12 and Figure 16 As shown, the charging system 1 includes a charging plug-in assembly 30, which has a plug-in module 35, such as Figure 16 As shown, the end face of the external device has two charging panels 91. The two charging panels 91 are arranged at intervals along the second direction F2 on one end face of the external device 90. The charging plug-in assembly 30 moves to the first charging panel 91 and plugs into the charging panel 91 to realize the charging of the first charging circuit. After the first charging circuit is fully charged, the charging plug-in assembly 30 is pulled out and moves along the second direction F2 to the second charging panel 91 to realize the charging of the second charging circuit.

[0130] In the above technical solution, by using a plug-in module 35 of a charging plug-in assembly 30 to alternately plug into multiple charging panels 91, multiple charging circuits can be charged without increasing the number of plug-in modules 35, which helps to reduce the size of the entire charging plug-in assembly 30 and reduce manufacturing costs.

[0131] like Figure 13 As shown, in some embodiments, the mobile module further includes a third mobile module 33, which is movably mounted on the second mobile module 32 along a third direction. A plug-in module 35 is disposed on the third mobile module 33. The plug-in module 35 is movable relative to the charging base 10 along the first mobile module 31, the second mobile module 32, and the third mobile module 33 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 90.

[0132] 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 controlled to move along the first direction F1, the second direction F2, and the third direction F3 to adjust the position of the charging connector 351, so that the charging connector 351 can be plugged into multiple charging panels 91 of the external device 90 to achieve charging of the multi-circuit external device 90.

[0133] Furthermore, through 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, enabling the plug-in module 35 to be accurately electrically connected to the corresponding charging panel 91. The plug-in accuracy and plug-in success rate of the plug-in module 35 when plugged into multiple charging panels 91 are higher.

[0134] In the above technical solution, 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 moving accuracy, so that the charging connector 351 can be plugged into the charging panel 91 of the external device 90 with high plugging accuracy and charging success rate; at the same time, there is no need for manual removal of the charging gun for alignment and switching, which saves labor costs and improves charging efficiency.

[0135] In some embodiments, the charging system 1 further includes a mobile platform 40, which is mounted on the charging base 10 and movable relative to the charging base 10 in a first direction F1. A charging plug-in assembly 30 is mounted on the mobile platform 40, and the mobile platform 40 is movable relative to the seating frame 20 to move the mobile platform 40 closer to and away from the seating frame 20.

[0136] 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.

[0137] 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.

[0138] In the above technical solution, the moving stage 40 drives the charging plug-in assembly 30 to move relative to the seating position of the external device, so as to achieve the initial positioning of the charging plug-in assembly 30 and the external device. The moving module 301 of the charging plug-in assembly 30 drives the charging connector 351 of the plug-in module 35 to move, so as to achieve the further positioning of the charging connector 351 and the charging port of the external device. This allows the charging connector 351 and the charging port to achieve more precise positioning and cooperation, 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 of the charging connector 351 and the charging port.

[0139] In some embodiments, the mobile station 40 has a first position and a second position arranged along a first direction F1, the first position being a seating position away from the external device relative to the second position, and the mobile station 40 being located at the first position when there is no external device at the seating position.

[0140] 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.

[0141] 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 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.

[0142] like Figures 1-3 As shown, in some embodiments, the charging device 2 further includes a protective cover 50. The protective cover 50 is mounted on the mobile platform 40 and has a receiving space 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 the charging port 911 on the external device 90.

[0143] The protective cover 50 and the moving platform 40 can be connected by fasteners, connectors, or other means. For example, the protective cover 50 and the moving platform 40 can be connected by multiple connectors spaced apart along the circumference of the moving platform 40. The connectors are bent plates, one part of which is connected to the cover of the protective cover 50 by fasteners, and the other part of which is connected to the moving platform 40 by fasteners.

[0144] 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 of the protective cover 50 may include a top wall and a peripheral wall, with the upper ends of the top wall and the peripheral wall connected to define an accommodating space. The bottom of the accommodating space has an opening to allow the cover to cover the charging plug-in assembly 30. The peripheral wall may be cylindrical or a prismatic shape composed of multiple flat side walls. The material of the cover may be, but is not limited to, high-strength low-carbon steel, aluminum alloy, stainless steel, composite materials (such as aluminum and insulation layers), etc.

[0145] Interface 512 refers to an opening provided on the protective cover 50. Interface 512 can penetrate the protective cover 50 along its wall thickness direction, allowing components within the receiving space to be inserted into or removed from components outside the receiving space. Interface 512 can be located at least at one location on the top wall and peripheral wall of the protective cover 50, for example... Figure 3 As shown, the protective cover 50 includes multiple sidewalls, one of which faces the external equipment and has an interface 512.

[0146] 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.

[0147] 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.

[0148] In some embodiments, continue to refer to Figure 3 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 90.

[0149] 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, 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.

[0150] 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.

[0151] The shield 52 is used to contact and engage with the outer wall of the external device 90. Therefore, when charging the external device 90 is required, the shield 52 of the protective cover 50 can first contact and engage with the outer wall of the external device 90, and then the charging connector 351 extends from the interface 512 and plugs into the charging port 911 of the external device 90 for charging. During charging, the shield 52 covers the gap between the protective cover 50 and the outer wall of the external device 90, 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 911 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.

[0152] 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, which is a replaceable power source for the electric vessel. That is, the box-type power supply acts as an external device, thereby enabling the electric vessel to swap batteries, reducing the waiting time for charging and swapping; and the box-type power supply can be charged on shore using the charging system 1, without being restricted by the location of the electric vessel, making the charging time more flexible, and also helping to improve the docking accuracy between the charging system 1 and the box-type power supply.

[0153] A charging system 1 according to a specific embodiment of this application is described below with reference to the accompanying drawings. It is to be understood that the following description is merely illustrative and should not be construed as limiting the application.

[0154] like Figures 1-17As shown, a charging system 1 according to a specific embodiment of this application includes a seating frame 20 and a charging device 2. The charging device 2 includes a charging base 10, a moving platform 40, a protective cover 50 and a charging plug-in assembly 30. The seating frame 20 is used to place an external device 90, and the external device 90 has two charging panels 91.

[0155] The seating frame 20 includes a support body 21, multiple guide structures 22, and two triggering mechanisms 23. The support body 21 is provided with multiple support parts 2101, which are located on the upper surface of the support body 21 and are used to support the external device 90. The support body 21 includes two first supports 211 and multiple second supports 212. Each first support 211 extends along the length direction of the external device 90. The two first supports 211 are arranged at intervals, and the multiple second supports 212 are connected between the two first supports 211. The first supports 211 and the second supports 212 are provided with support parts 2101.

[0156] The support body 21 also has multiple buffer pads 213, which are arranged at intervals along the circumference of the support body 21. The buffer pads 213 are arranged at intervals with the support part 2101, and the height of the buffer pads 213 is higher than the height of the support part 2101. When the external equipment 90 is placed, the external equipment 90 will first contact the buffer pads 213 after falling. Thus, the buffer pads 213 are compressed and absorb the impact kinetic energy, which can buffer the external equipment 90. This can prevent the external equipment 90 from being damaged and prevent the support part 2101 from being damaged by excessive impact or affecting its service life. After the buffer pads 213 are pressed to be flush with the support part 2101 (or slightly lower than the upper surface of the support part 2101), the external equipment 90 contacts the rigid support surface and completes the position locking.

[0157] Multiple guide structures 22 are spaced apart on the outer periphery of the support body 21. Each guide structure 22 includes a guide bracket 221 and a guide pad 222. The guide bracket 221 is connected to the outer periphery of the support body 21. A connecting piece 223 is provided on the outer periphery of the guide bracket 221. The connecting piece 223, the guide bracket 221 and the support body 21 are connected to each other.

[0158] The guide bracket 221 protrudes from the upper surface of the bracket body 21. The guide pad 222 is detachably provided on the guide bracket 221, and the guide pad 222 has a guide surface 2221. The guide surface 2221 extends obliquely from top to bottom and toward the bracket body 21. The guide structure 22 can guide the external device 90 through the guide surface 2221 during the process of placing the external device 90 on the seating frame 20.

[0159] Two triggering mechanisms 23 are symmetrical about the center of the bracket body 20. Both triggering mechanisms 23 must close simultaneously to determine that the external device 90 is installed correctly. Each triggering mechanism 23 includes a trigger switch 231, a trigger element 232, a guide element 233, and a reset element 234. The trigger element 232 is mounted on the guide element 233, and the upper end of the guide element 233 has a rollable ball 2334. The trigger switch 231 is fixed to the bracket body 21 and is used to determine whether the external device 90 is installed correctly. The external device 90 is supported on the guide element... When the external device 90 is placed on the guide 233, it comes into contact with the ball 2334. During the descent of the external device 90, the external device 90 will be displaced relative to the guide 233, thereby driving the trigger 232 to move. When the external device 90 is not placed on the seat 20, the trigger 232 is in the first position. When the external device 90 is seated in place, the trigger 232 can be moved to the second position. The trigger 232 only cooperates with the trigger switch 231 in the second position, thereby causing the trigger switch 231 to close.

[0160] In some specific examples, the bracket body 21 forms a mounting cavity 2102, and the trigger switch 231 is located in the mounting cavity 2102, thereby protecting the trigger switch 231 and extending the service life of the trigger switch 231.

[0161] The triggering mechanism 23 also includes a trigger seat 235, which is installed in the mounting cavity 2102 and connected to the bracket body 21. The trigger seat 235 defines a receiving cavity 2351. The upper surface of the bracket body 21 has a first through hole 2103 communicating with the receiving cavity 2351. A part of the guide member 233 and the reset member 234 are provided in the receiving cavity 2351. A part of the guide member 233 extends out of the receiving groove through the first through hole 2103. The receiving cavity 2351 can both protect the guide member 233 and limit its movement, ensuring that the guide member 233 moves in a predetermined direction, thereby ensuring the reliability of the triggering mechanism 23.

[0162] The guide member 233 includes a first guide section 2331 and a second guide section 2332 connected in sequence. The first guide section 2331 extends out of the receiving cavity 2351 through the first through hole 2103. The second guide section 2332 is disposed in the receiving cavity 2351, and the cross-sectional dimension of the second guide section 2332 is larger than that of the first guide section 2331. The second guide section 2332 can abut against the bracket body 21 to limit the trigger member 232 to the first position. The reset member 234 is located between the second guide section 2332 and the trigger seat 235.

[0163] The guide member 233 also includes a third guide segment 2333, which is connected to the end of the second guide segment 2332 away from the first guide segment 2331. The cross-sectional dimension of the third guide segment 2333 is smaller than that of the second guide segment 2332. The reset member 234 is sleeved on the outer periphery of the third guide segment 2333. The two ends of the reset member 234 abut against the bottom of the second guide segment 2332 and the trigger seat 235, respectively, thereby limiting the position of the reset member 234.

[0164] The trigger seat 235 has a second through hole 2352 at the end away from the first through hole 2103. The third guide section 2333 can pass through the second through hole 2352. Through the cooperation of the third guide section 2333 and the second through hole 2352, the movement of the guide member 233 is further limited, ensuring that the guide member 233 moves in a predetermined direction, thereby ensuring the reliability of the trigger mechanism 23.

[0165] The trigger seat 235 has a clearance groove 2353, which communicates with the receiving cavity 2351. The clearance groove 2353 is arranged opposite to the trigger switch 231. A part of the guide member 233 can extend out of the receiving cavity 2351 through the clearance groove 2353. The trigger member 232 is provided on the guide member 233 and can slide along the extension direction of the clearance groove 2353, thereby facilitating the cooperation between the trigger member 232 and the trigger switch 231.

[0166] The charging plug assembly 30 is used to connect to an external device 90 to charge the external device 90 via the charging plug assembly 30. A cable 61 is electrically connected to the charging plug assembly 30 to supply power to the charging plug assembly 30 via the cable 61.

[0167] The charging base 10 includes a charging frame 12 and two tracks 11 disposed on the charging frame 12. The charging frame 12 includes two first side beams 121 opposite each other along a first direction F1 and two second side beams 122 opposite each other along a second direction F2. Adjacent first side beams 121 are connected to second side beams 122, and the two tracks 11 are respectively disposed on the two second side beams 122.

[0168] The mobile platform 40 is movably mounted on the track 11 of the charging base 10 along the first direction F1 via movable wheels 41. A protective cover 50 is provided on the mobile platform 40 and encloses the charging plug assembly 30 on the mobile platform 40 to achieve a rainproof effect. The charging plug assembly 30 is movably mounted on the mobile platform 40.

[0169] The charging plug-in assembly 30 includes an active module and a plug-in module 35. The active module 301 includes a moving module and a swaying module 34. The moving module includes a first moving module 31, a second moving module 32, and a third moving module 33.

[0170] The first moving module 31 is movably disposed on the moving platform 40 and then on the charging base 10 along the first direction F1. The second moving module 32 is movably mounted on the first moving module 31 along the second direction F2. The third moving module 33 is movably mounted on the second moving module 32 along the third direction F3. The tilting module 34 is disposed between the third moving module 33 and the plug-in module 35. The tilting module 34 can drive the plug-in module 35 to rotate relative to the third moving module 33. The position and angle of the plug-in module 35 can be adjusted by the tilting module 34. The first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other.

[0171] The yaw module 34 includes a yaw drive 343 and a yaw table 341. The end of the yaw drive 343 is rotatably connected to the yaw table 341 via a ball joint 344.

[0172] The plug-in module 35 includes a connector panel 354 and a charging connector 351 and a positioning pin 352 disposed on the connector panel 354. A buffer structure 36 is disposed between the connector panel 354 and the tilting stage 341. One end of the positioning pin 352 has a positioning connector 3521, and the cross-sectional dimensions of the positioning connector 3521 gradually increase along the direction closer to the other end of the positioning pin 352.

[0173] The end face of the positioning socket 912 can be provided with a flared opening, thereby forming a positioning bevel 9121. The inclination angle of the positioning bevel 9121 is the same as the inclination angle of the bevel on the outer periphery of the positioning connector 3521. Thus, the positioning bevel 9121 can guide the positioning connector 3521, further improving the smoothness of the insertion of the positioning connector 3521 and improving the reliability of the charging plug-in assembly 30.

[0174] A plurality of limiting posts 353 are provided on one side of the connector panel 354. The plurality of limiting posts 353 are arranged at intervals along the circumference of the connector panel 354. The deflecting platform 341 has a limiting hole 342. The limiting posts 353 pass through the limiting hole 342. Through the sliding engagement of the limiting posts 353 and the limiting hole 342, the buffer structure 36 is sleeved on the outer periphery of the limiting posts 353. The buffer structure 36 is constructed to be deformable when the charging connector 351 is engaged with the charging port 911.

[0175] The plug-in module 35 is also equipped with an identification component 37, which includes a rangefinder 371, an image acquisition device 372, and an illumination device 373.

[0176] When it is necessary to charge the external device 90, the external device 90 is placed on the seat 20. The external device 90 drives the trigger 232 to move to the second position, the trigger switch 231 is closed, the moving platform 40 and the active component 301 are powered on and can be moved, and the identification component 37 is working.

[0177] Multiple rangefinders 371 detect the distance between the connector panel 354 of the plug-in module 35 and the charging panel 91. When the distance is too large, the movable module 301 moves to drive the plug-in module 35 to adjust the distance value to a predetermined range. When the distances detected by the multiple rangefinders 371 are different, it is found that the connector panel 354 has an angle with the charging panel 91 (i.e., the connector panel 354 and the charging panel 91 are not parallel). The movable module 301 moves to drive the plug-in module 35 to adjust the connector panel 354 to a position parallel to the charging panel 91. At this time, the connector panel 354 and the charging panel 91 are arranged approximately opposite each other in the first direction F1.

[0178] The image acquisition device 372 obtains the offset between the center of the positioning pin 352 and the center of the positioning hole 912 on the external device 90 by taking pictures and comparing. When the offset is greater than a certain value, the recognition component 37 transmits the offset to the activity module 301 in real time. The activity module 301 performs an activity to adjust the position of the plug-in module 35 until the acquired offset is zero. At this time, the center of the positioning pin 352 coincides with the center of the positioning hole 912 or is within the centering error range.

[0179] Therefore, by using vision and distance measurement, the charging posture of the plug-in module 35 is actively adjusted. At this time, the moving module 301 is further controlled to move along the first direction F1 to perform the insertion and engagement of the positioning pin 352 and the positioning hole 912. A part of the positioning connector 3521 can extend into the positioning hole 912. As the moving module 301 drives the plug-in module 35 to continue moving forward along the first direction F1, the inclined surface of the positioning connector 3521 can slide relative to the end face of the positioning hole 912 through the cooperation of the end face of the positioning hole 912 and the positioning connector 3521. At this time, the second moving drive 3... When 21 and the third moving drive 331 stop working, the positioning connector 3521 can drive the positioning pin 352, the connector panel 354 and the charging connector 351 to move along the second direction F2 and the third direction F3 until the outer periphery of the positioning connector 3521 is fully inserted into the positioning hole 912. At this time, the center of the positioning pin 352 coincides with the center of the positioning hole 912, thereby ensuring that the charging connector 351 corresponds to the position of the charging port 911. The moving module 301 drives the insertion and removal module 35 to continue to move forward along the first direction F1 until the charging connector 351 is inserted into the charging port 911.

[0180] As the plug-in module 35 moves, the length of the portion of the charging connector 351 extending into the charging port 911 gradually increases until the length of the portion of the charging connector 351 extending into the charging port 911 is consistent with the depth inside the charging port 911. When the movable module 301 drives the plug-in module 35 to continue moving, the buffer structure 36 can deform, giving the plug-in module 35 floating space. This allows the charging connector 351 and the charging port 911 to make flexible contact, thereby preventing the charging connector 351 from continuing to extend into the charging port 911 and causing collision damage between the charging connector 351 and the charging port 911, reducing the failure rate and increasing the service life. At the same time, through the deformation of the buffer structure 36, the charging connector 351 can maintain a predetermined pressure, thereby improving the reliability of the cooperation between the charging connector 351 and the charging port 911, and thus enabling stable charging of the external device 90.
