Description

Technical Field

[0001] This invention relates to a housing assembly for an electrical connection device, an electrical connection equipment, and a marine battery swapping system. Background Technology

[0002] Powering large transport equipment often requires a significant amount of electrical energy, resulting in larger battery volumes; for example, powering ships may necessitate batteries the size of shipping containers. Since inland river ports lack the infrastructure for building charging stations, battery swapping has become the primary technological approach. Charging stations are typically built approximately 3 kilometers from the port, and batteries are then delivered by vehicle and hoisted onto the vessel. Generally, ships are fully loaded with cargo during transport, requiring the battery boxes to be easily installed and removed without encroaching on cargo space; therefore, the ship's deck is the optimal location for battery box installation. This design exposes the battery boxes to an open outdoor environment, and the electrical connections between the ship and the battery boxes also operate outdoors, placing high demands on the waterproofing and protection capabilities of these connections. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to solve the waterproofing problem of electrical connection equipment, and to provide an electrical connection device housing assembly, electrical connection equipment and marine battery swapping system.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A housing assembly for an electrical connection device is provided for covering an electrical connection device that can be electrically connected to a battery box. The electrical connection device has a movable electrical connection assembly. The housing assembly includes a fixed part and a follower part connected to each other. The follower part is used to connect to the electrical connection assembly so that the follower part is kept covered outside the electrical connection assembly.

[0006] In this design, the follower part of the housing assembly can move together with the electrical connection assembly, so that the housing assembly can always cover the electrical connection assembly to meet the protection requirements of the movable electrical connection assembly and improve the reliability of the electrical connection.

[0007] Preferably, the fixing part includes a fixed cover, the following part includes a movable cover, the movable cover is located at one end of the cover assembly that is oriented in the same direction as the electrical connection direction, the movable cover is sleeved and connected to the fixed cover, and the movable cover can move relative to the fixed cover as the electrical connection assembly moves.

[0008] In this design, the movable cover and the fixed cover are fitted together, ensuring that the movable cover provides protection along the length of the cover assembly when it extends or retracts relative to the fixed cover, preventing gaps that could lead to protection failure. Furthermore, a sealing ring can be installed between the movable and fixed covers to seal any gaps between them. The electrical connection direction refers to the direction in which the electrical connection assembly moves towards the battery box to make electrical connection with it.

[0009] Preferably, the fixing part includes a fixed cover, and the following part includes a movable cover and a telescopic cover. The movable cover is located at one end of the cover assembly that is oriented in the same direction as the electrical connection direction. The movable cover can move relative to the fixed cover as the electrical connection assembly moves. The two ends of the telescopic cover are respectively connected to the fixed cover and the movable cover, and can extend and retract as the movable cover moves.

[0010] In this design, a telescopic cover is further installed between the movable and fixed housings to cover the gap between them in the direction of movement of the electrical connection assembly. This creates a unified protective structure, preventing rainwater and other contaminants from entering the housing assembly through the gap between the movable and fixed housings. With this structure, the movable and fixed housings can be separated without the need for additional sealing rings or other sealing structures, resulting in smoother movement of the movable housing.

[0011] Preferably, the telescopic cover is a cover formed of a flexible, continuous thin layer.

[0012] In this design, flexibility refers to deformability or stretchability, and continuous thin layer refers to a continuous thin-layer structure that is at least waterproof within the area covered by the telescopic cover. The telescopic cover can extend or shorten as the distance between its two ends changes. The telescopic cover can be a flexible, deformable and / or stretchable continuous film cover, accordion cover, corrugated cover, etc.

[0013] Preferably, a first frame is fitted onto the movable cover, a second frame is fitted onto the fixed cover, the two ends of the telescopic cover are respectively connected to the first frame and the second frame, and the telescopic cover at least partially covers the movable cover.

[0014] In this solution, the telescopic cover is connected to the first frame of the movable cover and the second frame of the fixed cover, thereby realizing the connection between the space between the fixed part and the movable cover, so that the fixed part and the movable cover form a whole to protect the electrical connection assembly.

[0015] Preferably, the second frame is disposed on the end of the fixed housing facing the same direction as the electrical connection direction, and within the range of movement of the electrical connection assembly, the second frame remains sleeved outside the movable housing;

[0016] And / or, the telescopic cover is provided with connecting frames at both ends, and the first frame and the second frame are respectively attached to and fixedly connected to the connecting frames at both ends of the telescopic cover.

[0017] In this design, the second frame is located at the end of the fixed housing facing the same direction as the electrical connection, thus facilitating the installation of the telescopic cover. The second frame remains fitted outside the movable housing within the range of motion of the electrical connection assembly, ensuring good rigidity of the housing assembly along its length during movement and improving protective performance.

[0018] Preferably, the housing assembly further includes a guide support mechanism, which includes a guide support rod that can extend and retract between the two ends of the telescopic housing, the guide support rod being used to support and guide the telescopic housing.

[0019] In this solution, the telescopic cover can be supported by a guide support mechanism to prevent the flexible telescopic cover from collapsing and deforming, thus hindering the extension and retraction of the movable cover.

[0020] Preferably, the guide support rod is a rigid rod, and the guide support mechanism further includes a guide seat. The guide seat is fixedly disposed relative to the fixed cover or the movable cover. The rigid rod passes through the guide seat, and the first end of the guide support rod is fixed relative to the end of the telescopic cover that is in the same direction as the electrical connection direction. The second end of the guide support rod extends in the opposite direction to the electrical connection direction and extends into the fixed cover, and can move along the axial direction of the guide support rod within the fixed cover.

[0021] Alternatively, the guide support rod may be a telescopic rod, with both ends of the telescopic rod fixed relative to the two ends of the telescopic cover.

[0022] In this solution, the guide support rod and guide seat can support and guide the telescopic cover, preventing it from collapsing or tilting during the telescopic cover's extension and retraction, thus improving the stability of the telescopic cover's extension and retraction process and avoiding interference with the relative movement between the fixed cover and the movable cover.

[0023] Preferably, the telescopic cover has multiple sequentially connected cover surfaces, the straight line at the connection point of two adjacent cover surfaces is parallel to the straight line of the electrical connection direction, and the support mechanism is disposed at the connection point of two adjacent cover surfaces inside the telescopic cover.

[0024] In this design, the support mechanism is located at the connection between the covers of the telescopic cover, thereby supporting the cover and creating an internal space for the cover.

[0025] Preferably, when the guide support rod is a rigid rod, the housing assembly further includes a first support frame and a second support frame, the first support frame and the second support frame being spaced apart in the electrical connection direction and being simultaneously disposed on the movable housing or simultaneously disposed on the fixed housing;

[0026] A mounting plate is connected between the first support frame and the second support frame, and the guide seat is disposed on the mounting plate. The first support frame and / or the second support frame are provided with avoidance holes for avoiding the guide support rod.

[0027] Preferably, both ends of the mounting plate are connected to the first support frame and the second support frame respectively via adjustment components, the adjustment components being used to adjust the position of the mounting plate so that the guide seat is coaxial with the rigid rod.

[0028] Preferably, the adjustment assembly includes an adjustment plate, an adjustment mechanism, and a locking mechanism;

[0029] The adjustment plate is disposed at the end of the mounting plate and has a connecting portion for connecting the first support frame or the second support frame, and an adjustment portion that interacts with the adjustment mechanism.

[0030] The adjustment mechanism includes a fixed seat disposed on the first support frame or the second support frame, an adjustment rod passing through the fixed seat and acting on the adjustment part at one end, and an adjustment nut for fixing the adjustment rod on the fixed seat.

[0031] The locking mechanism includes a fastening screw that passes through the connecting part and the first support frame or the second support frame, and a fastening nut for fastening the fastening screw. The connecting part is provided with an adjustment hole through which the fastening screw passes.

[0032] Preferably, the first support frame and the second support frame are simultaneously supported within the fixed cover, and the second support frame is located at one end of the fixed cover that is oriented in the same direction as the electrical connection direction, while the telescopic cover is connected to the second support frame at one end that is opposite to the electrical connection direction.

[0033] In this design, the first support frame and the second support frame are simultaneously supported within the fixed housing, which is relatively fixed. This makes the support of the first support frame and the second support frame for the guide support mechanism more stable. In addition, the second support frame can be reused, which can effectively utilize the space within the fixed housing and make the structure more compact.

[0034] An electrical connection device, characterized in that the electrical connection device includes an electrical connection means for electrical connection with a battery box and a housing assembly as described above;

[0035] The electrical connection device has a movable electrical connection assembly, the housing assembly including a fixed part and a follower part connected to each other, the follower part being connected to the electrical connection assembly so that the follower part is kept covered outside the electrical connection assembly.

[0036] In this solution, when the electrical connection assembly moves, it can drive the follower to move, so that the follower can make closer contact with the surface to be sealed, thereby improving the sealing performance.

[0037] Preferably, the electrical connection device further includes a connection mechanism, the connection mechanism including an elastic member connected between the electrical connection assembly and the follower, the elastic member being elastically deformable in the electrical connection direction to drive the follower to move along the electrical connection direction with the electrical connection assembly until the follower is stopped from moving.

[0038] In this design, the elastic element allows the follower part to move with the electrical connection assembly, ensuring close contact between the follower part and the surface to be sealed. When the follower part reaches a point of close contact with the surface and is stopped from moving further, the electrical connection assembly can continue to move forward, extending from the follower part to establish an electrical connection with the battery box. When the electrical connection is disconnected, the electrical connection assembly moves in the opposite direction of the connection. Due to the elastic force of the elastic element, the follower cover remains in contact with the battery box until the electrical connection assembly retracts to the follower part, sealing the interface.

[0039] Preferably, the connection mechanism further includes a reset member, which is used to apply a force opposite to the electrical connection direction to the follower when the electrical connection assembly moves in the opposite direction to the electrical connection direction.

[0040] In this design, after the electrical connection is disconnected and the electrical connection assembly is retracted into the follower section, the electrical connection assembly can apply a force opposite to the direction of the electrical connection to the follower section via the reset rod, thereby causing the follower section to reset. The presence of the reset rod limits the relative position of the follower cover to the electrical connection assembly on the straight line of the electrical connection direction during reset, ensuring that the follower cover always remains outside the electrical connection assembly.

[0041] Preferably, the electrical connection device further includes a guide assembly, the guide assembly including at least one guide mechanism disposed between the follower and the electrical connection assembly, the guide mechanism having a first sliding portion and a second sliding portion that are slidable relative to each other, the first sliding portion being disposed on the inner side of the follower and the second sliding portion being disposed on the outer side of the electrical connection assembly corresponding to the first sliding portion.

[0042] In this solution, the smoothness and guidance of relative movement can be improved by using guide components.

[0043] Preferably, the first sliding part and the second sliding part form a telescopic slide rail that can extend and retract along the straight line of the electrical connection direction;

[0044] And / or, the guiding assembly includes two guiding mechanisms, and the two guiding mechanisms are arranged opposite to each other.

[0045] Preferably, the electrical connection device further includes a chassis assembly and a drive unit disposed on the chassis assembly. The electrical connection assembly is movably disposed on the chassis assembly. The drive unit is drivenly connected to the electrical connection assembly to drive the electrical connection assembly to move. The fixing part is fixedly connected to the chassis assembly.

[0046] In this design, the fixing part can be fixedly connected to the chassis assembly, thereby enabling the chassis assembly to bear the weight of the cover assembly; it can also protect the chassis assembly and other components mounted on the chassis assembly through the cover assembly.

[0047] A shipboard battery swapping system includes a battery box for supplying power to the ship and electrical connection equipment as described above.

[0048] The positive and progressive effects of the present invention are that the follower part of the housing assembly can move together with the electrical connection assembly, so that the housing assembly can always cover the electrical connection assembly to meet the protection requirements of the movable electrical connection assembly and improve the reliability of the electrical connection.

[0104] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0105] This invention provides a housing assembly 1000 for an electrical connection device 100, such as... Figures 1-3As shown, the cover is used to cover the electrical connection device 100 that can be electrically connected to the battery box 20. The electrical connection device 100 has a movable electrical connection assembly 2000. The cover assembly 1000 includes a fixed part and a follower part 1200 connected to each other. The follower part 1200 is used to connect to the electrical connection assembly 2000 so that the follower part 1200 is kept covered outside the electrical connection assembly 2000.

[0106] In specific implementation, such as Figure 9 As shown, the electrical connection assembly 2000 is movable and electrically connected to the battery box 20. The electrical connection assembly 2000 is located inside the housing assembly 1000, and the follower part 1200 can move with the electrical connection assembly 2000. This allows the housing assembly 1000 to cover the outside of the electrical connection assembly 2000 before, during, and after the electrical connection between the electrical connection assembly 2000 and the battery box 20, in order to meet the protection requirements of the movable electrical connection assembly 2000 and improve the reliability of the electrical connection.

[0107] In a preferred embodiment, the fixing part includes a fixing cover 1110, and the following part 1200 includes a movable cover 1210. The movable cover 1210 is located at one end of the cover assembly 1000 that is oriented in the same direction as the electrical connection direction. The movable cover 1210 is sleeved and connected to the fixing cover 1110, and the movable cover 1210 can move relative to the fixing cover 1110 as the electrical connection assembly 2000 moves.

[0108] Here, the electrical connection direction refers to the direction in which the electrical connection assembly 2000 moves toward the battery box 20 to make an electrical connection with the battery box 20, that is... Figure 9 The direction indicated by the middle arrow x. In specific implementation, such as... Figure 3 As shown, in the initial state, i.e., when the electrical connection assembly 2000 is not electrically connected to the battery box 20, the cover assembly 1000 covers the electrical connection assembly 2000, and the end of the cover assembly 1000 facing the battery box 20 is located outside the electrical connection end of the electrical connection assembly 2000, thus in the electrical connection direction, i.e., the length direction of the cover assembly 1000. During the process of electrical connection between the electrical connection assembly 2000 and the battery box 20, the movable cover 1210 can move with the movement of the electrical connection assembly 2000, so that the cover assembly 1000 can also provide protection for the electrical connection assembly 2000 during the electrical connection process. This avoids gaps that could lead to protection failure. Furthermore, as... Figure 2As shown, after the end of the movable cover 1210 facing the battery box 20 contacts the battery box 20, the electrical connection assembly 2000 continues to move towards the battery box 20. The movable cover 1210, as the electrical connection assembly 2000 moves, fits tightly against the battery box 20, improving the sealing effect between the end face of the movable cover 1210 and the battery box 20. Furthermore, the portion where the movable cover 1210 and the fixed cover 1110 interlock ensures that even after the movable cover 1210 moves relative to the fixed cover 1110, the length of the cover assembly 1000 still provides protection. A sealing ring can also be provided between the movable cover 1210 and the fixed cover 1110 to seal the gap between them.

[0109] As another preferred implementation, such as Figures 1-3 As shown, the fixing part includes a fixed cover 1110, and the following part 1200 includes a movable cover 1210 and a telescopic cover 1220. The movable cover 1210 is located at one end of the cover assembly 1000 that is in the same direction as the electrical connection direction. The movable cover 1210 can move relative to the fixed cover 1110 as the electrical connection assembly 2000 moves. The two ends of the telescopic cover 1220 are connected to the fixed cover 1110 and the movable cover 1210 respectively, and can extend and retract as the movable cover 1210 moves.

[0110] like Figure 1 As shown, a telescopic cover 1220 is further provided between the movable cover 1210 and the fixed cover 1110. This telescopic cover 1220 covers the gap between the movable cover 1210 and the fixed cover 1110 in the moving direction of the electrical connection assembly 2000, making the movable cover 1210 and the fixed cover 1110 form a protective unit, preventing rainwater and other contaminants from entering the interior of the cover assembly 1000 from between the movable cover 1210 and the fixed cover 1110. With this structure, the movable cover 1210 and the fixed cover 1110 can be separated without the need for additional sealing structures such as sealing rings between them, resulting in smoother movement of the movable cover 1210.

[0111] In a preferred embodiment, the telescopic cover 1220 is a cover formed of a flexible, continuous thin layer.

[0112] Here, "flexible" refers to being deformable or stretchable, and "continuous thin layer" refers to a continuous thin-layer structure that is at least waterproof within the area covered by the telescopic cover 1220. The telescopic cover 1220 can extend or shorten as the distance between its two ends changes. The telescopic cover 1220 can be a flexible, deformable, and / or stretchable continuous film cover, accordion cover, corrugated cover, or other similar cover.

[0113] In the above embodiments, the fixed cover 1110 and the follower cover can be fitted together. Specifically, the fixed cover 1110 can be fitted over the follower cover, or the follower cover can be fitted over the fixed cover 1110. In practice, the corresponding settings can be made according to specific needs.

[0114] As a preferred implementation method, such as Figures 2-5 As shown, a first frame 1230 is fitted on the movable cover 1210, a second frame 1120 is provided on the fixed cover 1110, and the two ends of the telescopic cover 1220 are connected to the first frame 1230 and the second frame 1120 respectively, and the telescopic cover 1220 covers at least part of the movable cover 1210.

[0115] In specific implementation, such as Figure 2 As shown, taking the fixed cover 1110 fitted over the movable cover 1210 as an example, the outer side wall of the movable cover 1210 can be fitted with a first frame 1230, and the inner side wall of the fixed cover 1110 can be fitted with a second frame 1120. The second frame 1120 is disposed at one end of the fixed cover 1110 that is oriented in the same direction as the electrical connection direction. The first frame 1230 and the second frame 1120 can be used to connect the two ends of the telescopic cover 1220, thereby realizing the spatial connection between the fixed part and the movable cover 1210, so that the fixed part and the movable cover 1210 form an integral whole to protect the electrical connection assembly 2000. In other embodiments, the movable cover 1210 can be fitted over the fixed cover 1110, the first frame 1230 can be disposed on the inner side wall of the movable cover 1210, the second frame 1120 can be disposed on the outer side wall of the fixed cover 1110, and the telescopic cover 1220 can at least cover part of the fixed cover 1110.

[0116] In a preferred embodiment, the second frame 1120 is disposed on the end of the fixed cover 1110 that is oriented in the same direction as the electrical connection direction, and within the moving range of the electrical connection assembly 2000, the second frame 1120 remains sleeved on the movable cover 1210.

[0117] And / or, the telescopic cover 1220 is provided with connecting frames 1221 at both ends, and the first frame 1230 and the second frame 1120 are respectively attached to and fixedly connected to the connecting frames 1221 at both ends of the telescopic cover 1220.

[0118] In specific implementation, such as Figure 2 and Figure 3As shown, taking the fixed cover 1110 fitted over the movable cover 1210 as an example, the second frame 1120 is located at the end of the fixed cover 1110 facing the same direction as the electrical connection, and the first frame 1230 can be located on the side close to the battery box 20, thereby facilitating the installation of the telescopic cover 1220. The second frame 1120 can remain fitted over the movable cover 1210 within the moving range of the electrical connection assembly 2000, so that the cover assembly 1000 has good rigidity in the length direction during the movement of the electrical connection assembly 2000, thus improving the protective performance.

[0119] like Figure 8 As shown, the telescopic cover 1220 can be provided with connecting frames 1221 at both ends of the flexible body 1222, and connected to the first frame 1230 and the second frame 1120 through the connecting frames 1221, which facilitates the connection of the telescopic cover 1220 to the first frame 1230 and the second frame 1120. In specific implementation, the connecting frame 1221 is preferably fixed to the first frame 1230 or the second frame 1120 by bolts, forming a flange-type connection structure.

[0120] like Figure 1 and Figure 5 As shown, the electrical connection assembly 2000 is located on the chassis assembly 3000 of the electrical connection device 100. The housing assembly 1000 may have four covering surfaces other than the end facing the battery box 20 and the end facing the chassis assembly 3000, thereby avoiding space for the connection between the electrical connection assembly 2000 and the battery box 20, and also avoiding space for the connection between the electrical connection assembly 2000 and the chassis assembly 3000. Accordingly, depending on the actual protection requirements, partial covering surfaces may also be provided at the ends facing the battery box 20 and the chassis assembly 3000 to improve the protection effect on the electrical connection assembly 2000 and the chassis assembly 3000. Accordingly, as Figure 5 As shown, the first frame 1230 and the second frame 1120 can be U-shaped frame structures; wherein, as Figure 2 As shown, the second frame 1120, connected to the fixed housing 1110, can be fixedly connected to the chassis assembly 3000 to secure the fixed housing 1110 relative to the chassis assembly 3000. Specifically, as... Figure 5 As shown, the bottoms of the first frame 1230 and the second frame 1120 are fixedly connected to the chassis assembly 3000 via L-shaped bending plates.

[0121] As a preferred implementation method, such as Figures 2-5 As shown, the housing assembly 1000 also includes a guide support mechanism 1300, which includes a guide support rod 1310 that can extend and retract between the two ends of the telescopic cover 1220. The guide support rod 1310 is used to support and guide the telescopic cover 1220.

[0122] like Figure 2 As shown, the guide support mechanism 1300 is located inside the telescopic cover 1220. The guide support rod 1310 can extend along the electrical connection direction. The guide support rod 1310 can support the telescopic cover 1220, preventing the flexible telescopic cover 1220 from collapsing and deforming, thus hindering the extension and retraction of the movable cover 1210.

[0123] In practical implementation, the guide support mechanism 1300 can adopt various structural forms. Some feasible implementation methods will be given below.

[0124] In a preferred embodiment, the guide support rod 1310 is a rigid rod, and the guide support mechanism 1300 further includes a guide seat 1320. The guide seat 1320 is fixedly disposed relative to the fixed cover 1110 or the movable cover 1210. The rigid rod passes through the guide seat 1320, and the first end 1311 of the guide support rod 1310 is fixed relative to the end of the telescopic cover 1220 that is in the same direction as the electrical connection direction. The second end 1312 of the guide support rod 1310 extends in the opposite direction to the electrical connection direction and extends into the fixed cover 1110, and can move along the axial direction of the guide support rod 1310 within the fixed cover 1110.

[0125] like Figure 4 and Figure 5 As shown, the guide seat 1320 is fixedly disposed relative to the fixed cover 1110, and the guide support rod 1310 passes through the guide seat 1320. The first end 1311 of the guide support rod 1310 is fixed relative to the end of the telescopic cover 1220 that is in the same direction as the electrical connection direction. When the electrical connection assembly 2000 moves, it can drive the guide support rod 1310 to move within the guide seat 1320, thereby providing support for the telescopic cover 1220.

[0126] In another preferred embodiment, the guide support rod 1310 is a telescopic rod, with both ends of the telescopic rod fixed relative to the two ends of the telescopic cover 1220 shell.

[0127] In the above embodiments, the guide support rod 1310 and the guide seat 1320 can support and guide the telescopic cover 1220, preventing it from collapsing or tilting during the telescopic cover 1220's extension and retraction, thus improving the stability of the telescopic cover 1220's extension and retraction process and preventing interference with the relative movement between the fixed cover 1110 and the movable cover 1210.

[0128] As a preferred implementation method, such as Figure 1 As shown, the telescopic cover 1220 has multiple cover surfaces connected in sequence. The straight line where the connection point of two adjacent cover surfaces is located is parallel to the straight line where the electrical connection direction is located. The guide support mechanism 1300 is disposed at the connection point of two adjacent cover surfaces inside the telescopic cover 1220.

[0129] In specific implementation, such as Figure 1 As shown, the housing assembly 1000 may have four covering surfaces, excluding the end facing the battery box 20 and the end facing the chassis assembly 3000. The telescopic cover 1220, located between the movable cover 1210 and the fixed cover 1110, may have three covering surfaces, located above the top plate of the movable cover 1210 and outside the two side plates, respectively. Guide support mechanisms 1300 may be provided on both sides above the movable cover 1210, and the guide support rods 1310 may extend along the electrical connection direction and be located at the connection between two adjacent covering surfaces of the telescopic cover 1220. Thus, the guide support rods 1310 can support the telescopic cover 1220, providing an internal covering space; the telescopic cover 1220 can also protect the guide support mechanisms 1300.

[0130] In a preferred embodiment, when the guide support rod 1310 is a rigid rod, the housing assembly 1000 further includes a first support frame 1410 and a second support frame 1420. The first support frame 1410 and the second support frame 1420 are spaced apart in the electrical connection direction and are simultaneously disposed on the movable housing 1210 or simultaneously disposed on the fixed housing 1110.

[0131] A mounting plate 1430 is connected between the first support frame 1410 and the second support frame 1420. A guide seat 1320 is disposed on the mounting plate 1430. The first support frame 1410 and / or the second support frame 1420 are provided with clearance holes for avoiding the guide support rod 1310.

[0132] As a preferred implementation method, such as Figure 4 and Figure 5 As shown, the first support frame 1410 and the second support frame 1420 are simultaneously supported inside the fixed cover 1110, and the second support frame 1420 is located at one end of the fixed cover 1110 that is in the same direction as the electrical connection direction, and the end of the telescopic cover 1220 that is opposite to the electrical connection direction is connected to the second support frame 1420.

[0133] In specific implementation, such as Figure 4 and Figure 5 As shown, in a specific implementation, the first support frame 1410 and the second support frame 1420 can be spaced apart and arranged on the inner sidewall of the fixed cover 1110. The mounting plate 1430 is connected to the first support frame 1410 and the second support frame 1420, and thus the mounting plate 1430 can be connected to and disposed within the fixed cover 1110, which can be relatively fixed, thereby making the support of the first support frame 1410 and the second support frame 1420 for the guide support mechanism 1300 more stable. Figure 4 and Figure 5As shown, the second support frame 1420 can reuse the second frame 1120, which can effectively utilize the space inside the fixed cover 1110, making the structure more compact.

[0134] Furthermore, one end of the telescopic cover 1220 oriented in the same direction as the electrical connection can be fixed to the first frame 1230, and the first end 1311 of the guide support rod 1310 can be fixed to the first frame 1230, thereby allowing the first end 1311 of the guide support rod 1310 to be fixed relative to the end of the telescopic cover 1220 oriented in the same direction as the electrical connection. Additionally, the fixed housing 1110 can be fixedly connected to the chassis assembly 3000, the first end 1311 of the guide support rod 1310 is fixedly connected to the first frame 1230, and the guide seat 1320 is mounted on the fixed housing 1110. Thus, the fixed cover 1110 is relatively fixed, for example, fixed to the chassis assembly 3000. The guide seat 1320 is connected to the fixed cover 1110 through the mounting plate 1430. The guide support rod 1310 passes through the guide seat 1320 and is fixedly connected to the movable cover 1210. The guide support rod 1310 can not only support the telescopic cover 1220, but also support the movable cover 1210. Furthermore, the guide seat 1320 can bear the weight of the guide support rod 1310, the telescopic cover 1220, and the movable cover 1210. The guide seat 1320 is also connected to the fixed cover 1110, which can provide support for it, so that the movable cover 1210 can move with the movement of the electrical connection assembly 2000.

[0135] In a preferred embodiment, the two ends of the mounting plate 1430 are connected to the first support frame 1410 and the second support frame 1420 respectively via the adjustment assembly 1500. The adjustment assembly 1500 is used to adjust the position of the mounting plate 1430 so that the guide seat 1320 is coaxial with the rigid rod.

[0136] In specific implementation, such as Figure 6 and Figure 7 As shown, the adjustment component 1500 can be disposed below the mounting plate 1430 and the mounting plate 1430 can be adjusted vertically to adjust the vertical position of the guide seat 1320 so that the guide seat 1320 is coaxial with the rigid rod.

[0137] As a preferred implementation method, such as Figure 6 and Figure 7 As shown, the adjustment assembly 1500 includes an adjustment plate 1510, an adjustment mechanism 1520, and a locking mechanism 1530;

[0138] The adjustment plate 1510 is disposed at the end of the mounting plate 1430, and has a connecting portion 1511 for connecting the first support frame 1410 or the second support frame 1420, and an adjustment portion 1512 that interacts with the adjustment mechanism 1520.

[0139] The adjustment mechanism 1520 includes a fixed base 1521 disposed on the first support frame 1410 or the second support frame 1420, an adjustment rod 1522 passing through the fixed base 1521 and acting on the adjustment part 1512 at one end, and an adjustment nut 1523 for fixing the adjustment rod 1522 to the fixed base 1521.

[0140] The locking mechanism 1530 includes a fastening screw 1531 that passes through the connecting part 1511 and the first support frame 1410 or the second support frame 1420, and a fastening nut 1532 for fastening the fastening screw 1531. The connecting part 1511 is provided with an adjustment hole 1533 through which the fastening screw 1531 passes.

[0141] In specific implementation, such as Figure 6 and Figure 7 As shown, the end of the mounting plate 1430 has a connecting portion 1511, which fits against the first support frame 1410 or the second support frame 1420. The adjusting hole 1533 can be an oblong hole, which extends along the adjusting direction of the adjusting mechanism 1520, for example, it can extend vertically. The locking mechanism 1530 is connected to the oblong hole, and the connecting portion 1511 can move along the adjusting direction under the action of the adjusting mechanism 1520. The end of the mounting plate 1430 also has an adjusting portion 1512. The adjusting rod 1522 of the adjusting mechanism 1520 acts on the adjusting portion 1512, thereby driving the mounting plate 1430 to move in the adjusting direction.

[0142] like Figure 6 As shown, the connecting part 1511 is provided on the end face of the mounting plate 1430 facing the first support frame 1410 and the second support frame 1420, and the adjusting part 1512 is provided below the mounting plate 1430 and is connected to the mounting plate 1430 through the bending part 1513. In other embodiments, the adjusting rod 1522 may also act directly on the mounting plate 1430.

[0143] This invention also provides an electrical connection device 10, such as... Figure 9 As shown, the electrical connection device 10 includes an electrical connection device 100 that can be electrically connected to the battery box 20 and a housing assembly 1000 as described above.

[0144] The electrical connection device 100 has a movable electrical connection assembly 2000. The housing assembly 1000 includes a fixed part and a follower part 1200 connected to each other. The follower part 1200 is connected to the electrical connection assembly 2000 so that the follower part 1200 is kept covered outside the electrical connection assembly 2000.

[0145] Therefore, when the electrical connection assembly 2000 moves, it can drive the follower 1200 to move, so that the follower 1200 can make closer contact with the surface to be sealed, thereby improving the sealing performance.

[0146] As a preferred implementation method, such as Figure 2 and Figure 3 As shown, the electrical connection device 10 also includes a connection mechanism, which includes an elastic member 4100 connected between the electrical connection assembly 2000 and the follower 1200. The elastic member 4100 can be elastically deformed in the electrical connection direction to drive the follower 1200 to move along the electrical connection direction with the electrical connection assembly 2000 until the follower 1200 is stopped from moving.

[0147] Thus, the elastic element 4100 enables the follower portion 1200 to move with the electrical connection assembly 2000, ensuring close contact between the follower portion 1200 and the surface to be sealed. When the follower portion 1200 reaches a point of close contact with the surface and is prevented from moving further, the electrical connection assembly 2000 can continue to move forward, extending from the follower portion 1200 to establish an electrical connection with the battery box 20. When the electrical connection is disconnected, the electrical connection assembly 2000 moves in the opposite direction of the electrical connection. Due to the elastic force of the elastic element 4100, the follower cover remains in contact with the battery box 20 until the electrical connection assembly 2000 retracts to the follower portion 1200, sealing the interface.

[0148] As a preferred implementation method, such as Figure 2 and Figure 3 As shown, the connection mechanism also includes a reset member 4200, which is used to apply a force in the opposite direction to the electrical connection direction to the follower 1200 when the electrical connection assembly 2000 moves in the opposite direction to the electrical connection direction.

[0149] Therefore, after the electrical connection is disconnected and the electrical connection assembly 2000 is retracted into the follower part 1200, the electrical connection assembly 2000 can apply a force opposite to the direction of the electrical connection to the follower part 1200 via the reset rod, thereby causing the follower part 1200 to reset. The presence of the reset rod can limit the relative position of the follower cover with respect to the electrical connection assembly 2000 on the straight line of the electrical connection direction during reset, so that the follower cover always remains outside the electrical connection assembly 2000.

[0150] As a preferred implementation method, such as Figure 10As shown, the electrical connection device 10 also includes a guide assembly 4300. The guide assembly 4300 includes at least one guide mechanism disposed between the follower portion 1200 and the electrical connection assembly 2000. The guide mechanism has a first sliding portion 4310 and a second sliding portion 4320 that can slide relative to each other. The first sliding portion 4310 is disposed on the inner side of the follower portion 1200, and the second sliding portion 4320 is disposed on the outer side of the electrical connection assembly 2000 corresponding to the first sliding portion 4310.

[0151] Thus, the smoothness and guidance of relative movement can be improved by the guide component 4300.

[0152] As a preferred implementation method, such as Figure 10 As shown, the first sliding part 4310 and the second sliding part 4320 form a telescopic slide rail that can extend and retract along the straight line of the electrical connection direction;

[0153] And / or, the guide assembly 4300 includes two guide mechanisms, which are arranged opposite to each other.

[0154] As a preferred implementation method, such as Figure 2 As shown, the electrical connection device 100 also includes a chassis assembly 3000 and a drive unit 3100 disposed on the chassis assembly 3000. The electrical connection assembly 2000 is movably disposed on the chassis assembly 3000. The drive unit 3100 is connected to the electrical connection assembly 2000 in a transmission connection to drive the electrical connection assembly 2000 to move. The fixing part is fixedly connected to the chassis assembly 3000.

[0155] This allows the chassis assembly 3000 to bear the weight of the housing assembly 1000; it also allows the housing assembly 1000 to protect the chassis assembly 3000 and other components mounted on the chassis assembly 3000.

[0156] In specific implementation, such as Figure 2 and Figure 3 As shown, the end of the housing assembly 1000 facing the electrical connection direction may also be provided with a protective door 4400. In the initial state, the protective door 4400 falls down, thereby protecting the electrical connection assembly 2000 located inside the housing assembly 1000. When the electrical connection device 100 docks with the battery box 20, the protective door 4400 opens upward to avoid the docking space of the electrical connection assembly 2000. In addition, the end of the housing assembly 1000 facing the electrical connection direction may also be provided with a sealing part 4500. After the movable housing 1210 contacts the battery box 20, when the electrical connection assembly 2000 moves further in the electrical connection direction, the movable housing 1210 also moves accordingly, and the sealing part 4500 can be squeezed to improve the sealing effect and also prevent deformation due to rigid contact between the movable housing 1210 and the battery box 20.

[0157] This invention also provides a ship battery swapping system 1, such as... Figure 9 As shown, it includes a battery box 20 for supplying power to the ship and an electrical connection device 10 as described above.

[0158] While specific embodiments of the present invention have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of the present invention is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but all such changes and modifications fall within the scope of protection of the present invention.
