Description

Technical Field

[0001] This invention relates to an electrical connection device with a correction function, as well as ships and charging / swapping stations incorporating the same. Background Technology

[0002] To promote the strategy of converting oil-to-electricity transportation, the approach has been extended from land transportation to sea transportation. Since inland river ports lack the basic conditions for building charging stations, battery swapping has become the main technical route, with charging stations built about 3 kilometers away from the port, and vehicles used for short-distance delivery.

[0003] When ships use battery swapping for power replenishment, the high range of battery requirements due to the ship's navigation in water necessitates the installation of ultra-large battery boxes. Furthermore, to enable rapid battery swapping, the battery boxes are typically locked to the ship's deck, placing them in the open. This makes the battery boxes highly susceptible to external factors, such as the ship's movement in water and water currents washing over the ship's interior or the battery boxes. Additionally, because the battery boxes are containerized and hoisted onto the ship for rapid swapping, some gaps inevitably exist between the battery box and the ship's connection devices during installation, preventing a seamless connection. These factors pose significant challenges to the reliability and safety of electrical connections in ship battery swapping. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the problems of unreliable and unsafe electrical connections in ship battery swapping, and to provide an electrical connection device with a correction function, as well as a ship and a charging and swapping station containing the device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] An electrical connection device with a correction function, characterized in that the electrical connection device comprises:

[0007] Base;

[0008] A base that can be movably mounted on the base;

[0009] A floating plate is connected to the base, and an electrical connector for electrical connection with an external battery box is installed on the floating plate. The floating plate can move relative to the base with the base to make electrical connection with the battery box. The floating plate is connected to the base along the length and width directions of the floating plate so that the floating plate can move in its plane, thereby adjusting the electrical connector to a position for electrical connection with the battery box. An elastic element is also provided between the floating plate and the base so that the electrical connector can move toward or away from the base to always maintain a contact state when electrically connected to the battery box.

[0010] The electrical connection device has an electrical connector that connects to an external battery box. The connector moves under the drive of the base. A floating plate set relative to the base allows the connector to float in a direction perpendicular to the connection direction. This allows the connector to mitigate the alignment error when the connector is not aligned with the component to be connected on the external battery box, ensuring that the connector can reliably complete the connection.

[0011] Meanwhile, the elastic element between the floating plate and the base can alleviate the movement error of the base relative to the base, keep the electrical connector aligned with the external battery box, and make the connection between the two more secure through the reaction force of the elastic element.

[0012] This design ensures that the electrical connection between the battery box and the battery box remains tightly connected even if the ship shakes during operation.

[0013] Preferably, the electrical connection device further includes a first floating assembly, which includes a plurality of first elastic elements that connect the two ends of the floating plate along the width direction to the base respectively.

[0014] In this technical solution, the first elastic element can make the floating plate float and adjust at both ends in the width direction. When there is a deviation in the width direction, when the electrical connector needs to be adjusted in position during docking with the battery box, the floating plate compresses the first elastic element located on the side of the deviation direction to alleviate the alignment error and realize docking with the charging port.

[0015] Preferably, the plurality of first elastic elements located at both ends of the floating plate in the width direction are evenly spaced along the length direction.

[0016] In this technical solution, the uniformly arranged first elastic element can ensure that the force in the width direction on both sides of the connecting plate in the length direction remains balanced, and will not cause tilting on both sides.

[0017] Preferably, a plurality of the first elastic elements are disposed at least at the end corners of the floating plate.

[0018] In this technical solution, by setting the first elastic element at the corner of the floating plate, the floating plate is subjected to uniform force, thereby improving the ability of the first elastic element to compensate for positional deviations.

[0019] Preferably, the electrical connection device further includes a second floating assembly, which includes a plurality of second elastic elements that connect the two ends of the floating plate along the length direction to the base respectively.

[0020] In this technical solution, the second elastic element can make the floating plate float and adjust at both ends of the length direction. When there is a deviation in the length direction, when the electrical connector needs to be adjusted in position during docking with the battery box, the floating plate compresses the second elastic element located on the side of the deviation direction to alleviate the alignment error and realize docking with the charging port.

[0021] Preferably, a plurality of the second elastic elements are disposed at least at the midpoint of both ends of the floating plate along the length direction.

[0022] In this technical solution, the second elastic element located in the middle position can ensure that the forces in the length direction on both ends of the connecting plate remain balanced and will not cause tilting on both sides.

[0023] Preferably, the floating plate includes a floating panel and a connecting plate fixed to the floating panel. The electrical connector is mounted on the floating panel. The connecting plate is connected to the base through the first elastic member and the second elastic member. The connecting plate is configured to be adjustable in position relative to the floating panel along the width direction so that the first elastic members at both ends along the width direction are subjected to balanced forces and the electrical connector can be held in a preset position to facilitate electrical connection between the electrical connector and the battery box.

[0024] In this technical solution, the connecting plate can move relative to the floating panel while being connected. Therefore, with the initial relative positions of the connecting plate and the base fixed, the electrical connector on the floating panel can be kept in its preset position by adjusting the position of the floating panel relative to the connecting plate.

[0025] Specifically, the floating plate adjusts its position in the width direction by setting a connecting plate, so that the first elastic element located on the upper and lower sides is subjected to balanced force, so that the tension of the first elastic element can be fully contributed to the floating, and so that the floating plate and the electrical connector can be kept in the center position, so as to facilitate reliable electrical connection between the electrical connector and the external battery box.

[0026] Preferably, the floating plate further includes a connecting component to connect the connecting plate and the floating panel. The connecting plate and the floating panel are respectively provided with a first mounting hole and a second mounting hole for the connecting component to pass through and be fixed. One of the first mounting hole and the second mounting hole is a round hole and the other is an oblong hole. The long axis of the oblong hole corresponds to the width direction.

[0027] In this technical solution, the relative position of the connecting plate and the floating panel can be adjusted by the movement of the connecting component in the waist-shaped hole, thereby guiding and ensuring that the connecting plate moves along the long axis direction of the predetermined waist-shaped hole, that is, the width direction, to achieve the corresponding adjustment.

[0028] Preferably, the floating plate further includes adjustment components, at least two of which abut against both ends of the connecting plate along the width direction to adjust the position of the connecting plate relative to the floating panel.

[0029] In this technical solution, the adjustment components at both ends can push the connecting plate to move in opposite directions, thereby realizing bidirectional adjustment of the connecting plate in the width direction.

[0030] Meanwhile, the adjusted side adjustment components can press against the two side surfaces of the connecting plate, so that the position of the connecting plate relative to the floating panel in the width direction remains fixed, and the adjustment position is more accurate.

[0031] Preferably, the adjustment assembly includes a fixing part disposed on the floating panel and an adjustment part passing through the fixing part. One end of the adjustment part abuts against the end face of the connecting plate, and the other end of the adjustment part is configured to be force-applied so that the adjustment part can move relative to the fixing part to adjust the position of the connecting plate relative to the floating panel.

[0032] In this technical solution, the position of the connecting plate can be adjusted by applying force to the adjusting part, simplifying the adjustment operation. At the same time, it avoids contact with other parts such as the floating panel and the connecting plate, enabling adjustment within a confined internal space.

[0033] Preferably, the electrical connection device further includes a guide shaft, a first end of which is connected to the floating plate, and a second end of which is configured to pass through the elastic member and pass through the base;

[0034] When the floating plate is compressed during the electrical connection process, the floating plate and the guide shaft can move towards the base, causing the elastic element to be compressed, and the electrical connector can always remain in contact with the battery box when electrically connected.

[0035] In this technical solution, a guide shaft is set to limit the elastic element, so that the elastic element is kept extending or retracting in the direction of approaching or moving away from the base.

[0036] Preferably, the first end of the guide shaft passes through the floating plate with a clearance fit, so that the floating plate is tilted relative to the first end of the guide shaft.

[0037] In this technical solution, the gap between the floating plate and the guide shaft allows the floating plate to have a certain tilt angle, thereby enabling the floating plate to adapt to the battery box in terms of tilt angle and ensuring reliable connection between the electrical connector and the battery box, further enhancing the adaptability.

[0038] Preferably, the electrical connection device further includes a limiting sleeve, which is sleeved outside the elastic member and the guide shaft, and located between the floating plate and the base.

[0039] By setting a limiting sleeve, the floating amount of the floating plate is limited, preventing the floating plate and guide shaft from moving excessively backward unreasonably; at the same time, it also protects the elastic element and guide shaft, preventing other objects from entering the position of the elastic element and guide shaft and affecting the extension and contraction of the elastic element.

[0040] Preferably, the end of the limiting sleeve adjacent to the base has an extension that extends outward and / or inward along the plane of the floating plate.

[0041] The above structural design increases the contact area with the base, facilitating stress distribution and preventing stress concentration.

[0042] Preferably, a sensor is also provided on the base, the sensor being disposed corresponding to the second end of the guide shaft, and used to detect the displacement of the second end of the guide shaft relative to the base to confirm that the electrical connector is properly connected to the battery box.

[0043] By setting a sensor on the base to detect the relative position of the second end of the guide shaft, when the electrical connection device is electrically connected to the battery box, the base moves along the direction of electrical connection with the floating plate. The floating plate abuts against the battery box and is pressed, so that the floating plate and the guide shaft can move relative to the base in a direction opposite to the direction of electrical connection. By setting a sensor to detect the displacement of the guide shaft at the second end, the relative displacement is used to determine whether the electrical connector and the battery box are properly connected.

[0044] Preferably, the electrical connection device further includes at least one guide member disposed on the floating plate near the electrical connector, the guide member being used to cooperate with a positioning hole disposed on the battery box to drive the floating plate to adjust its position.

[0045] In this solution, the electrical connection device is aligned with the battery box by means of guide members and positioning holes, and the floating plate enables the electrical connector to quickly reach the electrical connection position and align with the corresponding electrical connector, thereby improving alignment efficiency and accuracy.

[0046] Preferably, there are two guide members, which are respectively disposed at a predetermined distance between the two sides of the electrical connector, so that a sealing ring for sealing the electrical connector can be accommodated between the electrical connector and the guide member.

[0047] In this design, when the two guide members are inserted into their corresponding positioning holes, the corresponding electrical connectors used for electrical connection can be accurately aligned, improving alignment accuracy. The sealing ring prevents water from entering the electrical connector location, avoiding leakage and improving safety.

[0048] The electrical connection device further includes a protective cover, which covers the base and the floating plate and moves with the base. The protective cover is slidably connected to the base. When the protective cover abuts against the battery box, the base moves further toward the battery box by causing the floating plate to slide relative to the protective cover, so that the electrical connector is electrically connected to the battery box.

[0049] This electrical connection assembly features a protective cover that moves with the base, providing rain and water protection while ensuring the electrical connector remains covered during movement, thus meeting the connector's waterproof requirements. Furthermore, because the protective cover is slidable relative to the base, it prevents the cover from pressing against the battery box surface and affecting reliable connection between the connector and the battery box as the connector moves towards the battery box with the base.

[0050] The protective shield includes:

[0051] The first cover unit is disposed on the base;

[0052] The second cover unit is movable with the base;

[0053] And a third cover unit, the two ends of which are respectively connected to the first cover unit and the second cover unit, and the third cover unit can be stretched or contracted as the base moves.

[0054] The protective cover has a three-section structure, with the first and second cover units located at both ends on the base and pedestal respectively. This ensures that the base in this area is always covered by the protective cover. At the same time, since the third cover unit can extend and retract with the movement of the pedestal, the protective cover keeps covering the entire electrical connector and pedestal during the movement of the electrical connector. This prevents external environmental factors such as rain from affecting the normal operation of the moving mechanism and improves the operational reliability of the electrical connection device.

[0055] The electrical connection device further includes a tension spring and a sliding assembly. The two ends of the tension spring are respectively connected to the second cover unit and the base, and the tension spring is preset with a corresponding tension force so that the second cover unit moves when the base moves. The sliding assembly has a first end and a second end that can slide relative to each other along the electrical connection direction. The first end of the sliding assembly is fixed to the outer surface of the base, and the second end of the sliding assembly is fixed to the inner surface of the second cover unit.

[0056] By incorporating a tension spring with a certain amount of tension, the second cover unit can move along with the electrical connection part, preventing the second cover unit from sliding when it is not in contact with the battery box. This ensures that the second cover unit maintains its position covering the electrical connector and base under normal circumstances, improving rain protection. Simultaneously, the sliding component allows the electrical connection part to continue moving to maintain electrical connection with the battery box after the cover is in contact with it. This ensures rain protection for the electrical connection part in this state while also limiting the displacement of the cover relative to the base. The structure is simple and highly reliable. Furthermore, the sliding component is hidden inside the cover, preventing rainwater from affecting normal sliding.

[0057] The electrical connection device includes a guide mechanism that limits the movement of the base relative to the subbase along the electrical connection direction, the guide mechanism comprising:

[0058] A slide rail is provided on the base along the electrical connection direction;

[0059] At least two sliders are disposed on the slide rail and respectively connected to the base, with each slider located below the base.

[0060] Multiple slide rails are placed below the base to facilitate the slide rails and sliders to bear the weight of the electrical connection parts. At the same time, the base and rain cover are used to protect against rain and prevent rainwater from seeping into the slider and affecting the normal operation of the guiding mechanism.

[0061] The electrical connection device includes a drive unit that drives the base to move toward the battery box, and the drive unit further includes:

[0062] A lead screw is disposed on the base along the guiding direction of the guide mechanism, and the rotation shaft of the motor of the drive unit is connected to the lead screw;

[0063] A nut, which is sleeved on the lead screw and disposed on the base.

[0064] By using a lead screw to drive the nut to move horizontally, the base is driven and thus the electrical connector moves. This drive scheme has a large torque output, runs smoothly, and is effectively adapted to ensure smooth docking of the electrical connector with external components to be connected.

[0065] A swappable battery vessel includes the aforementioned electrical connection device with a correction function, the electrical connection device being electrically connected to the vessel's battery box to provide a power source for the vessel.

[0066] This battery-swappable vessel utilizes floating plates positioned relative to its base, enabling the electrical connectors to move along the connection direction and float perpendicular to it. This allows for alignment errors between the connectors and the components to be connected on the vessel's battery box, mitigating the misalignment and ensuring reliable connection. Furthermore, even during vessel movement, the electrical connection remains firmly attached to the battery box, with the elastic reaction force further enhancing the bond.

[0067] This structural design ensures that even if the ship shakes during navigation, the electrical connection between the battery box and the battery box remains secure, preventing the risk of power outages due to ship movement.

[0068] A charging and battery swapping station for a ship's fast-swap battery includes the aforementioned electrical connection device with a correction function, wherein the electrical connection device is electrically connected to the ship's fast-swap battery to charge the ship's fast-swap battery.

[0069] This charging and battery swapping station for ships uses a floating plate positioned relative to the base to enable the electrical connector to move along the insertion direction and float in a direction perpendicular to the insertion direction. This allows the electrical connector to mitigate the alignment error when it is not aligned with the component to be connected on the ship's fast-swap battery, ensuring that the electrical connector can reliably complete the connection. Furthermore, the reaction force of the elastic element makes the connection between the two more secure.

[0070] The positive and progressive effects of this invention are as follows:

[0071] This electrical connection device with correction function, along with the ship and charging / swapping station containing it, allows the electrical connector, which connects to the external battery box, to move under the drive of the base. A floating plate positioned relative to the base enables the connector to float in a direction perpendicular to the connection direction. This allows the connector to mitigate alignment errors when misalignment occurs between the connector and the components to be connected on the external battery box, ensuring reliable docking. Simultaneously, an elastic element between the floating plate and the base mitigates movement errors of the base relative to the base, maintaining docking between the connector and the external battery box, and the reaction force of the elastic element further strengthens the connection.

[0072] This structural design ensures that the electrical connection between the battery box and the battery box remains tight even if the ship shakes during operation, thus avoiding the risk of power outage due to the ship's movement. Attached Figure Description

[0119] The present invention will be described more clearly and completely below with reference to a preferred embodiment and the accompanying drawings.

[0120] This embodiment discloses an electrical connection device 1000 with a correction function, wherein, as shown in the example... Figures 1-5 As shown, the electrical connection device 1000 of this embodiment includes a base 300, a base 500, a floating plate 100, an electrical connector 200, and a protective cover 800. The base 500 is disposed on the base 300 and moves along the front-rear direction Z under the drive of the drive unit 910. The electrical connector 200 is mounted on the floating plate 100 for electrical connection. The floating plate 100 is connected to the base 500 along its length direction X and width direction Y via a first floating component 41 and a second floating component 42, respectively, so that the floating plate 100 can float in its plane (i.e., the plane perpendicular to the front-rear direction Z), thereby adjusting the electrical connector 200 to allow connection with an external battery box. Figure 1 (As shown in the middle) The position for electrical connection is provided to alleviate the alignment error of the electrical connector 200 relative to the battery box. In addition, an elastic element 390 is provided between the floating plate 100 and the base 500. The elastic element 390 allows the floating plate 100 and the electrical connector 200 to float in the direction of approaching or moving away from the base 500 (i.e., the front-to-back direction Z), so that the electrical connector 200 can always maintain a contact state when electrically connected to the battery box.

[0121] The protective cover 800 is positioned above the base 500, the floating plate 100, and the electrical connector 200, and also wraps around the floating plate 100 and the electrical connector 200 from both sides in the length direction X, so as to improve the rainproof and waterproof effect on precision components such as the electrical connector 200 when the electrical connection device 1000 is installed outdoors.

[0122] Among them, from Figure 2 As can be seen, the end of the protective cover 800 covers the entire electrical connector 200, and the electrical connector 200 does not protrude from the protective cover 800, so that the protective cover 800 can provide reliable protection for the electrical connector 200 when not docked. When the base 500, floating plate 100 and electrical connector 200 move toward the battery box under the drive of the drive unit 910, the protective cover 800 will first abut against the surface of the battery box. At this time, since the protective cover 800 is movable relative to the base 500, the drive unit 910 can continue to drive the base 500, floating plate 100 and electrical connector 200 toward the battery box while the protective cover 800 is abutting against the surface of the battery box, so that the electrical connector 200 is docked with the battery box.

[0123] The electrical connector 200 of the electrical connection device 1000, which connects to the external battery box, is realized by the drive unit 910 driving the base 500 to move forward. By setting a first floating component 41 and a second floating component 42 between the base 500 and the floating plate 100, the electrical connector 200 can float along a direction perpendicular to the insertion direction (i.e., the length direction X and the width direction Y). In case of misalignment between the electrical connector 200 and the component to be connected on the external battery box, the relative floating of the floating plate 100 can alleviate the alignment error and ensure that the electrical connector 200 can reliably complete the connection.

[0124] Meanwhile, the elastic element 390 is provided between the floating plate 100 and the base 500, which can alleviate the movement error of the base 500 relative to the base 300, keep the electrical connector 200 connected to the external battery box, and make the connection between the two more tight by the reaction force of the elastic element.

[0125] In this embodiment, the length direction X and width direction Y are located in a plane perpendicular to the docking direction of the electrical connector 200. The front-to-back direction Z is parallel to the docking direction of the electrical connector 200. The first floating component 41, the second floating component 42, and the elastic element 390 can be various mechanisms capable of floating or elastically moving in response to changes in force.

[0126] In this embodiment, the floating plate 100 can move within its plane through the synergistic effect of the first floating component 41 and the second floating component 42. Furthermore, by providing the elastic element 390, the floating plate 100 can also move in the forward-backward (Z) direction. This allows the electrical connector 200 and the floating plate 100 to float together in all directions, adapting to any deviation between the electrical connector 200 and the charging port of the battery box, thus avoiding damage caused by a rigid connection between the electrical connector 200 and the charging port. The forward-backward (Z) floating motion ensures a tighter connection between the electrical connector 200 and the charging port. Moreover, the adjustment process of the electrical connector 200 is automatically achieved during the insertion process, without the need for control equipment, making it simple and quick.

[0127] like Figure 3 and Figure 5 As shown, the electrical connection device 1000 also includes two guide members 700 positioned near the electrical connector 200 and fixed to the floating plate 100. These guide members 700 are distributed along the length X on both sides of the floating plate 100. Each guide member 700 engages with a positioning hole on the battery box to adjust the position of the floating plate 100. By engaging the guide members 700 with the positioning holes on the battery box, the alignment reliability between the electrical connection device 1000 and the battery box is ensured. Furthermore, the floating of the floating plate 100 allows the electrical connector 200 to quickly reach its electrical connection position and align with the corresponding electrical connector, improving alignment efficiency and accuracy. Two guide members 700 are positioned at a certain interval on both sides of the electrical connector 200, allowing a sealing ring for sealing the electrical connector 200 to be accommodated between the electrical connector 200 and the guide members 700. This structural arrangement provides sufficient space between the guide members 700 and the electrical connector 200 for the sealing ring, preventing water from entering the electrical connector 200, avoiding leakage, and improving safety. A conical surface 710 is provided at the end of the guide member 700 facing the battery box (see...). Figure 5 This reduces the difficulty of alignment when the guide 700 mates with the positioning hole on the battery box.

[0128] like Figure 6 As shown, the electrical connector 200 extends into the base 500 via multiple connector cables 210 on the side near the base 500, and then exits via a cable chain 930 (see...). Figure 3 This allows for connection to external power supply equipment or electrical appliances. Simultaneously, as the electrical connector 200 and the floating plate 100 move together, the connector cable 210 moves accordingly, and the space within the base 500 ensures that the connector cable 210 can extend, retract, and move internally.

[0129] like Figure 4As shown, in this embodiment, the first floating component 41 includes a plurality of first elastic elements 410, which connect the two ends of the floating plate 100 to the base 500 along the width direction Y. The first elastic elements 410 enable the floating plate 100 to float and be adjustable in the width direction Y. When there is a deviation in the width direction, and the electrical connector 200 needs to be adjusted in position during docking with the battery box, the floating plate 100 compresses the first elastic element 410 located on the side of the deviation direction to alleviate the alignment error.

[0130] Specifically, at both ends of the floating plate 100 in the width direction Y, these first elastic elements 410 are evenly spaced along the length direction X to ensure that the force exerted by each first elastic element 410 on the floating plate 100 is uniform and distributed, and will not cause tilting on both sides due to uneven force.

[0131] like Figure 4 As shown, there are four first elastic elements 410 in this embodiment, and the ends of the first elastic elements 410 connected to the floating plate 100 correspond to the four corner positions of the floating plate 100. By placing the first elastic elements 410 at the corner positions of the floating plate 100, the floating plate 100 is subjected to uniform force, thereby improving the ability of the first elastic elements 410 to compensate for positional deviations.

[0132] like Figure 4 As shown, the second floating assembly 42 includes multiple second elastic elements 420, which connect the two ends of the floating plate 100 along the length direction X to the base 500. The second elastic elements 420 enable the floating plate 100 to float and be adjustable in the length direction X. When there is a deviation in the length direction, and the electrical connector 200 needs to be adjusted in position during docking with the battery box, the floating plate 100 compresses the second elastic element 420 located on the side of the deviation direction to alleviate the alignment error.

[0133] Specifically, there are two second elastic members 420, which are respectively disposed at the middle positions of both ends of the floating plate 100 along the length direction X. This ensures that the ends of the second elastic members 420 are connected to the middle positions of the floating plate 100, so that the force from the second elastic members on both ends of the entire floating plate 100 along the length direction X can remain balanced and will not tilt.

[0134] Of course, in other embodiments, the first elastic element 410 and the second elastic element 420 can also be set and arranged in various ways.

[0135] In this embodiment, both the first elastic element 410 and the second elastic element 420 are springs, specifically tension springs. Of course, in other embodiments, the first floating assembly 41 of the first elastic element 410 and the second elastic element 420 may not be limited to springs, but may adopt other structures capable of floating, such as pneumatic rods, hydraulic rods, rubber parts, and other elastic restoring elements that can deform and provide restoring force.

[0136] like Figure 5 and Figure 6 As shown, in this embodiment, there are four elastic elements 390, evenly distributed at the four corner positions of the floating plate 100. To facilitate the demonstration of the internal structure, [details omitted]. Figure 5 A limiting sleeve 370 is concealed within the structure, exposing the elastic element 390 corresponding to the sleeve 370, while the other three elastic elements 390 are covered by three other limiting sleeves 370. These elastic elements 390 are positioned between the floating plate 100 and the base 500, providing the floating plate 100 with a forward and backward Z-direction floating capability.

[0137] In this embodiment, the electrical connection device 1000 further includes a guide shaft 310, the first end of the guide shaft 310 (i.e. Figure 5 The right end of the guide shaft 310 is connected to the floating plate 100, and the second end 310b of the guide shaft 310 (i.e. Figure 5 The left end of the guide shaft 310 is configured to pass through the elastic member 390 and be installed in the base 500, so that when the floating plate 100 is compressed during the electrical connection process, the floating plate 100 and the guide shaft 310 can move in the direction of the base 500 (i.e., the front-back direction Z) so that the elastic member 390 is compressed and the electrical connector 200 can always remain in contact with the battery box when electrically connected.

[0138] The limiting sleeve 370 is sleeved outside the elastic element 390 and the guide shaft 310, and is located between the floating plate 100 and the base 500. The limiting sleeve limits the floating amount of the floating plate 100, preventing the floating plate 100 and the guide shaft 310 from excessively moving backward. At the same time, the limiting sleeve 370 also protects the floating plate 100 and the guide shaft 310, preventing other objects from entering the positions of the elastic element 390 and the guide shaft 310 and affecting the sliding of the guide shaft 310 and the extension and retraction of the elastic element 390.

[0139] The limiting sleeve 370 has an extension at the end adjacent to the base 500, which extends outward and / or inward along the plane of the floating plate 100, increasing the contact area with the base 500, facilitating force distribution and avoiding stress concentration.

[0140] like Figure 5 and Figure 6As shown, the first end of the guide shaft 310 passes through the floating plate 100 and is clearance-fitted relative to the floating plate 100, causing the floating plate 100 to tilt relative to the first end of the guide shaft 310. The gap between the floating plate 100 and the guide shaft 310 allows the floating plate 100 to have a certain tilt angle, thereby enabling the electrical connector 200 to adapt to the charging port in terms of tilt angle, further enhancing its adaptability. In other embodiments, the first end of the guide shaft 310 may also be connected to the floating plate 100 in other ways, such as by directly fixing them together.

[0141] like Figure 6 As shown, in a further preferred embodiment, the electrical connection device 1000 further includes a sensor (not shown in the figure). The sensor is mounted inside the base 500 via a sensor support 320 and is positioned opposite to the end of the second end 310b of the guide shaft 310, with a predetermined distance between them. When the electrical connection device 1000 is electrically connected to the battery box, the base 500, carrying the floating plate 100, moves along the electrical connection direction (i.e., the front-to-back direction Z). The floating plate 100 abuts against the battery box and is pressed. The floating plate 100 and the guide shaft 310 can move a predetermined distance toward the base 500 so that the sensor detects the approaching movement of the second end 310b of the guide shaft 310, thereby confirming that the electrical connector 200 is properly aligned with the battery box.

[0142] In addition, such as Figure 6 As shown, when the electrical connection device 1000 is connected to an external device, the guide shaft 310 drives the floating plate 100 to move towards the base 500. The sensor detects the end of the second end of the guide shaft 310, indicating that the electrical connector 200 and the battery box are properly connected. The drive motor 913 of the control drive unit 910 stops operating. Simultaneously, the elastic element 390 is continuously compressed, generating a reaction force that keeps the electrical connector 200 in contact with the battery box. In this embodiment, sensors are respectively installed on opposite sides of the second ends of the two diagonally opposite guide shafts 310. During the connection process, as long as one sensor detects the end of the second end 310b of the guide shaft 310, it can be determined that the electrical connector 200 and the battery box are properly connected. Furthermore, using two sensors increases the recognition rate.

[0143] like Figure 4 and Figure 7As shown, the floating plate 100 includes a floating panel 110 and a connecting plate 120 fixed to the floating panel 110. An electrical connector 200 is mounted on the floating panel 110. The connecting plate 120 is connected to the base 500 via first elastic members 410 and second elastic members 420. Specifically, multiple first elastic members 410 connect the two ends of the connecting plate 120 along the width direction Y to the base 500, and multiple second elastic members 420 connect the two ends of the connecting plate 120 along the length direction X to the base 500. The connecting plate 120 is configured to be adjustable relative to the floating panel 110 along the width direction Y, ensuring that the first elastic members 410 at both ends along the width direction Y are subjected to balanced force and that the electrical connector 200 is held in a preset position for electrical connection with the battery box. The connecting plate 120 can also move relative to the floating panel 110 while connected to it. Therefore, with the initial relative positions of the connecting plate 120 and the base 500 fixed, the position of the floating panel 110 relative to the connecting plate 120 can be adjusted to keep the electrical connector 200 on the floating panel 110 in its preset position for docking with the battery box. Furthermore, since the forces on each of the first elastic members 410 at both ends along the width direction Y are balanced, the amount of floating of the first elastic members 410 in the width direction Y can be provided to the floating panel 110, eliminating the need to correct their own position before floating.

[0144] Specifically, such as Figure 7 and Figure 8 As shown, in this embodiment, the floating plate 100 further includes a connecting component 130 for connecting the connecting plate 120 and the floating panel 110. The connecting plate 120 and the floating panel 110 are respectively provided with a first mounting hole and a second mounting hole for the connecting component 130 to pass through and be fixed. Specifically, in this embodiment, the first mounting hole on the connecting plate 120 is an oblong hole 122, with its major axis corresponding to the width direction Y. The second mounting hole on the floating panel 110 is a round hole. In other embodiments, the first mounting hole on the connecting plate 120 may be a round hole, and the second mounting hole on the floating panel 110 may be an oblong hole. The connecting component 130 connects the connecting plate 120 and the floating panel 110 and allows them to move relative to each other, making the relative position of the connecting plate 120 and the floating panel 110 adjustable. Simultaneously, the oblong hole 122 guides the connecting component 130 and the floating panel 110, i.e., guides them along the width direction Y. In this embodiment, the connecting component 130 uses bolts and nuts. Of course, in other embodiments, other components that can slide and be fixed can also be used, such as sliders or other fasteners that are fixed to the connecting plate 120 or the floating panel 110 and can slide relative to the waist-shaped hole 122.

[0145] like Figure 7As shown, the floating plate 100 also includes adjustment components 600. There are at least two adjustment components 600, which abut against both ends of the connecting plate 120 along the width direction Y to adjust the position of the connecting plate 120 relative to the floating panel 110. The adjustment components 600 simplify operation, allowing adjustment of the floating panel 110 simply by operating them. Each of the two adjustment components 600 can push the connecting plate 120 in a mutual direction, thus achieving bidirectional adjustment of the connecting plate 120 in the width direction Y. Simultaneously, the adjusted side adjustment components 600 press against both sides of the connecting plate 120, keeping the position of the connecting plate 120 relative to the floating panel 110 fixed in the width direction Y.

[0146] like Figure 7 As shown, the adjustment assembly 600 includes a fixing part 610 and an adjustment part 620. The fixing part 610 is disposed on the floating panel 110, and the adjustment part 620 passes through the fixing part 610. One end of the adjustment part 620 abuts against the end face of the connecting plate 120, and the other end of the adjustment part 620 is configured to be force-applied, allowing the adjustment part 620 to move relative to the fixing part 610 to adjust the position of the connecting plate 120 relative to the floating panel 110. The position of the connecting plate 120 can be adjusted by applying force to the adjustment part 620, simplifying the adjustment operation. Figure 12 As shown, the adjustment part 620 can be seen through the gap between the floating panel 110 and the base 500. When the adjustment part 620 is further configured as a bolt or other tool-adjustable component, a tool such as a screwdriver can be inserted into the interior while avoiding contact with other positions such as the floating panel 110 and the connecting plate 120. The adjustment bolt can be rotated using a tool such as a screwdriver to achieve adjustment in the narrow internal space.

[0147] like Figure 7 and Figure 8 As shown, the connecting plate 120 has a bent plate 121 extending into the receiving groove. The other ends of the first elastic member 410 and the second elastic member 420 are respectively connected to corresponding positions on the bent plate 121, such that the two ends of the first elastic member 410 and the two ends of the second elastic member 420 remain in the same plane. This ensures that the force direction of the first elastic member 410 and the second elastic member 420 is parallel to the plane of the floating plate 100, thereby avoiding affecting the position of the floating plate 100 in other directions.

[0148] In a preferred embodiment, four connecting components 130 and four adjusting components 600 are provided. The floating panel 110 has two electrical connectors 200 arranged along the width direction Y. Four connecting components 130 are provided in the area between the two electrical connectors 200. The connecting components 130 are also arranged in an inverted trapezoidal shape along the width direction Y. The adjusting parts 620 of the adjusting components 600 abut against the bent plates 121 on both sides along the width direction Y. Specifically, when it is necessary to adjust the position of the floating panel 110 relative to the connecting plate 120, the bolts and nuts can be loosened to allow the floating panel 110 and the connecting plate 120 to move relative to each other. The adjusting parts 620 are then turned to move the connecting plate 120 relative to the floating panel 110 in the width direction Y until the adjustment is in place. The adjusting parts 620 are then tightened to ensure that each adjusting part 620 abuts against the connecting plate 120. Finally, the bolts and nuts are tightened to ensure that the position of the floating panel 110 relative to the connecting plate 120 is fixed. By adjusting the relative positions of the floating panel 110 and the connecting plate 120, the force on each of the first elastic elements 410 on both sides along the length direction X is balanced, so as to ensure that the floating amount of the first elastic element 410 in the width direction Y is given to the floating panel 110, without needing to correct its own position first during the floating process.

[0149] Specifically, such as Figure 9 As shown, the protective cover 800 in this embodiment specifically includes: a first cover unit 810, a second cover unit 820 and a third cover unit 830.

[0150] The first cover unit 810 is mounted on the base 300 through its fixed end 810a, achieving a stable connection with the base 300. The second cover unit 820 is connected to the base 500 through the mounting hole 820a located on the inner surface of the cover, achieving a follow-up movement relative to the base 500. The two ends of the third cover unit 830 are respectively connected to the first cover unit 810 and the second cover unit 820. In this embodiment, the third cover unit 830 is a bellows cover with a telescopic function. Therefore, it can be stretched or contracted synchronously with the horizontal movement of the base 500 relative to the base 300, maintaining the function of protecting other components in the electrical connection device 1000 from rain.

[0151] The protective cover 800, through the aforementioned three-section structure, places the first cover unit 810 and the second cover unit 820 at both ends on the base 300 and the base 500 respectively, so that the base 300 in this area is always covered by the protective cover. At the same time, since the third cover unit 830 can extend and retract with the movement of the electrical connection part, the protective cover 800 keeps covering the entire base 500 during the movement of the base 500, avoiding the impact of external environmental factors such as rain on the normal operation of the base 500 and the moving mechanism, thus improving the operational reliability of the electrical connection device 1000.

[0152] In addition, the protective cover 800 also includes guide support rods 840. Both sets of guide support rods 840 are located on the inner top of the third cover unit 830 and are arranged along the sides of the third cover unit 830 along its extension and retraction direction. The specific locations are as follows: Figure 10 As shown, in Figure 10 With the third cover unit 830 concealed, it can be seen that two sets of guide support rods 840 are positioned between the first cover unit 810 and the second cover unit 820. Specifically, one end of each guide support rod 840 is fixed to the end of the third cover unit 830 near the second cover unit 820, and the other end extends to the first cover unit 810 and is movable or retractable relative to the first cover unit 810. This restricts the movement freedom of the second cover unit 820 to a range of Z-direction movement. Furthermore, the outer surface 2010 of the guide support rod 840 contacts the inner surface 2010 of the third cover unit 830, allowing these two sets of guide support rods 840 to support the third cover unit 830 and prevent the flexible third cover unit 830 from collapsing in the middle.

[0153] The specific structure of the guide support rod 840 is as follows: Figure 11 As shown, Figure 11 This is a schematic diagram showing the partial concealment of the first cover unit 810. It can be seen that the guide support rod 840 specifically includes a guide rod 841 connected to the second cover unit 820 and a positioning seat 842 fixed to the first cover unit 810. The positioning seat 842 has a through hole for accommodating the guide rod 841, allowing the guide rod 841 to slide relative to the positioning seat 842. This allows the second cover unit 820 to move with the base 500, thereby enabling the third cover unit 830 to slide and be guided relative to the first cover unit 810. By placing two sets of guide support rods 840 on both sides of the protective cover 800, the second cover unit 820 and the third cover unit 830 can smoothly extend and retract relative to the first cover unit 810.

[0154] By setting the guide support rod 840, the position of the first cover unit 810 relative to the second cover unit 820 can be realized, thereby improving the rigidity of the protective cover 800 itself and preventing the protective cover 800 from deforming over a long period of time.

[0155] In this embodiment, as Figure 12 and Figure 13 As shown, the electrical connection device 1000 also includes a tension spring 860, a limiting rod 870, and a sliding assembly 850. The second cover unit 820 of the protective cover 800 is connected to the base 500 through the tension spring 860 and the sliding assembly 850, and is limited relative to the base 500 through the limiting rod 870.

[0156] The specific connection relationships are as follows: Figure 12As shown, the second cover unit 820 of the protective cover 800 has a first end face 820b that is away from the battery box 2000. A tension spring 860 is provided between the base 500 and the first end face 820b of the second cover unit 820 to realize the elastic connection between the base 500 and the second cover unit 820. The tension spring 860 is preset with a corresponding tension force so that when the base 500 moves in the front-back direction Z, the second cover unit 820 can move together with the base 500 under the action of the tension spring 860.

[0157] By setting a tension spring 860 with a certain tension, the second cover unit 820 can move with the base 500, preventing the second cover unit 820 of the protective cover 800 from sliding when it is not in contact with the battery box 2000. This allows the second cover unit 820 to maintain the state of covering the base 500 under normal circumstances, thus improving the rainproof effect.

[0158] In addition, such as Figure 12 As shown, one end of the limiting rod 870 is fixed to the first end face 820b, and the other end of the limiting rod 870 extends toward the base 500. Under the tension of the tension spring 860, if the second cover unit 820 is not against the battery box 2000, the other end of the limiting rod 870 abuts against the base 500, thereby limiting the second cover unit 820 relative to the base 500.

[0159] In addition, such as Figure 12 As shown, sliding components 850 are also provided on both sides of the base 500. The sliding component 850 has a first end 851 and a second end 852 that can slide relative to each other (see...). Figure 13 The first end 851 of the sliding component 850 is fixed to the outer surface of the base 500, and the second end 852 of the sliding component 850 is fixed to the mounting hole 820a of the second cover unit 820 by screws. When the second cover unit 820 of the protective cover 800 abuts against the side surface of the battery box 2000, the base 500 can continue to move relative to the protective cover 800 in the front-back direction Z, so as to move further toward the battery box 2000, thereby realizing the purpose of electrical connection between the electrical connector 200 and the battery box 2000.

[0160] Therefore, the relative movement relationship between the base 500 and the second cover unit 820 of the protective cover 800 is as follows: Figure 14 and Figure 15 As shown. First, driven by the drive unit 910, the base 500 moves the protective cover 800 toward the battery box 2000. At this time, under the action of the tension spring 860 and the limit rod 870, the protective cover 800 remains as shown. Figure 10 The relative position of the center to the base 500 is used to shield the base 500 and achieve the purpose of rain protection.

[0161] Because the second cover unit 820 protrudes more, it will first abut against the side surface 2010 of the battery box 2000. At this time, under the continuous drive of the drive unit 910, the base 500 continues to move forward in the front-rear direction Z. Specifically... Figure 11 As shown, the second cover unit 820 has already abutted against the side surface 2010 of the battery box 2000 and cannot move forward any further. Therefore, by the stretching of the tension spring 860 and the guidance of the sliding component 850, the second cover unit 820 moves relative to the base 500 in a direction opposite to the front-rear direction Z while remaining abutted against the battery box 2000, so that the electrical connector 200 is docked with the battery box 2000.

[0162] After the charging operation is completed, the drive unit 910 drives the base 500 to retract relative to the battery box 2000. During the retraction process, the tension force output by the tension spring 860 keeps the second cover unit 820 against the battery box 2000 until the end of the limit rod 870 abuts against the first end 1a of the base 500. After that, the second cover unit 820 and the base 500 move together and retract as a whole. When the electrical connector 200 is disconnected from the battery box 2000 and resets, the limit rod 870 limits the retraction of the electrical connector 200 and the base 500 to prevent excessive retraction of the base 500 from affecting other components or causing damage.

[0163] The structure of the drive unit 910 in this embodiment is as follows: Figure 16 As shown, the system includes a lead screw 911, a nut 912, and a drive motor 913. The drive motor 913 is mounted on the base 300, and its rotation shaft is connected to the lead screw 911, driving the lead screw 911 to rotate. The nut 912 is threaded onto the lead screw 911 and connected to it, and is also connected to the lower surface of the base 500. Under the operation of the drive motor 913, the nut 912 moves along the extension direction of the lead screw 911, causing the base 500 to move in the forward-backward direction Z. By setting up the lead screw 911 and nut 912, and using the motor to drive the lead screw 911 to rotate, the nut 912 moves horizontally, achieving the purpose of moving the base 500. This drive scheme has a large torque output, smooth operation, and is effectively adapted to ensure smooth docking of the base 500 and the battery box 2000.

[0164] Additionally, the electrical connection device 1000 in this embodiment further includes a guide mechanism 920 for limiting the movement of the base 500 relative to the base 300 to movement in the front-rear direction Z, such as... Figure 16 As shown, there are two sets of guide mechanisms 920 in this embodiment, which are distributed on both sides of the drive unit 910 and are respectively connected to the base 500 for moving and guiding. They are evenly stressed and have good stability.

[0165] In this embodiment, each guide mechanism 920 includes a slide rail 921 and two sliders 922. The slide rail 921 is disposed on the upper surface of the base 300 along the front-rear direction Z. The two sliders 922 are sequentially disposed on the slide rail 921. The upper surfaces of the sliders 922 are respectively connected to the lower surface of the base 500, and both sliders 922 are disposed below the base 500. This structural arrangement, with the slide rail 921 disposed below the base 500, facilitates the slide rail 921 and sliders 922 in bearing the weight of the base 500. At the same time, the base 500 and the protective cover 800 provide rain protection, preventing rainwater from seeping into the sliders 922 and affecting the normal operation of the guide mechanism 920.

[0166] In addition, such as Figure 3 As shown, the base 500 and the base 300 are connected by two parallel cable chains 930. The two cable chains 930 are of different sizes to accommodate cables of different specifications, guiding power cords and other cables connected to the base 500 and preventing bending of the cables during horizontal movement of the base 500. This is in the case where the protective cover 800 is installed on the base 300 (see...). Figure 1 and Figure 2 The first cover unit 810 of the protective cover 800 can cover the cable chain 930 to prevent rainwater from dripping onto the cables inside, thereby further improving the rainproof function.

[0167] This embodiment also discloses a battery-swappable vessel, which includes a battery box and an electrical connection device 1000. The electrical connection device 1000 is electrically connected to the battery box to provide a power source for the battery-swappable vessel. This structural arrangement of the electrical connection device 1000 ensures that the battery box remains tightly connected to the battery box even if the vessel shakes during operation, avoiding the risk of power outage due to the vessel's movement.

[0168] This embodiment also discloses a charging and battery swapping station for a ship's fast-swap battery, which has an electrical connection device 1000 that is electrically connected to the ship's fast-swap battery to charge the fast-swap battery.
