[0042] The following describes in detail the overall structure, working principle, and technical effects of the battery transfer system 030 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0043] Please refer to Figures 1-3 The battery transfer system 030 provided by this utility model is used to replace the battery 020 and can be applied in scenarios such as ports and ships 010.

[0044] Please refer to Figures 1-3 The present invention proposes a battery transfer system 030, comprising:

[0045] The battery swapping box 100 is installed on the deck 011 of the ship 010. The battery swapping box 100 includes two support parts 110. A battery compartment 012 is provided below the deck 011. The two support parts 110 are located on both sides of the extension direction of the battery compartment 012. The battery compartment 012 is provided with multiple individually provided battery positions 013 for placing batteries 020.

[0046] The traveling component 200 has two ends that are slidably connected to the top of two support parts 110 respectively, and the traveling component 200 is provided with a lifting component 230.

[0047] The battery lifting device 300 is used to hook the battery 020. The battery lifting device 300 is connected to the lifting component 230, which is used to drive the battery lifting device 300 to move up and down.

[0048] Understandably, by placing the battery compartment 012 at the bottom of the deck 011, each battery 020 can be isolated individually by the battery position 013 within the battery compartment 012, facilitating independent fire protection. The fire protection system can meet the thermal runaway management requirements of all batteries 020, making it safer than the existing battery transfer system 030. By setting up the battery swapping box 100, the trolley assembly 200, and the battery hoist 300, this application only needs to move in two directions to achieve battery swapping, which is one less direction of movement compared to the existing battery transfer system 030. The battery swapping time is reduced from 30 minutes to less than 20 minutes, improving the transfer efficiency of the batteries 020. At the same time, the battery transfer system 030 with this configuration has a simple structure and small size, leaving ample walking space on the deck 011.

[0049] In this application, the movement can be understood in two directions: 1. The vehicle assembly 200 moves horizontally along the two support parts 110; 2. The battery hoist 300 moves vertically relative to the vehicle assembly 200.

[0050] In this embodiment, the battery transfer system 030 battery 020 includes a battery swapping box 100.

[0051] The battery swapping box 100 is installed on the deck 011 of the ship 010. The battery swapping box 100 includes two support parts 110. The battery swapping box 100 can provide protection for the battery 020 and other equipment. The two support parts 110 can be used to support the trolley assembly 200 to work.

[0052] In this embodiment, please refer to Figure 3 The battery transfer system 030 includes a battery swapping box 100, which includes a frame structure 021 and a roof 120. The frame structure 021 is provided with side panels on the left, right and rear sides, and a baffle is provided on the front side of the frame structure 021. The roof 120 is located on the top of the frame structure 021. The left and right sides of the frame structure 021 form a support part 110.

[0053] Please refer to Figure 4 Each of the two support portions 110 is provided with a guide rail 130 at its top; the guide rail 130 is arranged along the extending direction of the support portion 110. The guide rail 130 can provide guidance for the traveling component 200, guiding the traveling component 200 to travel along a predetermined route, ensuring that the traveling component 200 does not deviate from the track, thereby ensuring travel safety.

[0054] Please refer to Figures 3-4 Limiting stops 140 are provided at the front end of the two guide rails 130 and at the rear of the frame 021 structure. The limiting stops 140 can ensure that the traveling component 200 moves within a safe range.

[0055] In this embodiment, please refer to Figures 1-2 Below the deck 011 is a battery compartment 012, and two support parts 110 are located on both sides of the extension direction of the battery compartment 012. The battery compartment 012 has multiple individually set battery positions 013, which are used to place batteries 020.

[0056] Each battery 020 is equipped with a frame 021 on its top, which is used by the battery lifting device 300 to hook the battery 020.

[0057] In this embodiment, a buffer position for buffering battery 020 is provided on the deck 011. The buffer position is located inside the battery swapping box 100. The buffer position and multiple battery positions 013 are arranged sequentially along the extension direction of the support 110. The buffer position is located at the front end of the battery swapping box 100, and the battery compartment 012 is located at the rear end of the battery swapping box 100.

[0058] Please refer to Figure 2 The cache bits include a first cache bit 014 and a second cache bit 015 arranged in sequence. The first cache bit 014 is used to cache a fully charged battery 020, and the second cache bit 015 is used to cache a low-charged battery 020.

[0059] In this embodiment, please refer to Figure 2 The battery compartment 012 is equipped with multiple sequentially arranged partitions 0121, which divide the battery compartment 012 into multiple individually configured chambers, with the battery compartment 013 individually located within each chamber. The battery compartment 012 is also equipped with a water injection hole for injecting fire-fighting water into the battery compartment 012.

[0060] The separator 0121 separates each battery 020, so that if one battery 020 experiences thermal runaway, it will not affect the other batteries 020.

[0061] Understandably, when battery 020 experiences thermal runaway, the fire hydrant inlet opens, allowing fire hydrant water to be injected into battery compartment 012 to extinguish the fire in battery 020. Battery compartment 012 can hold the fire hydrant water to submerge the thermally runaway battery 020, thus playing a role in extinguishing the fire.

[0062] In this embodiment, please refer to Figures 1-3A power distribution room 016 is installed on deck 011, located near support 110. The power distribution room 016 is connected to batteries 020 in battery compartment 012 and is used to distribute and control the electrical energy output from batteries 020. Specifically, the power distribution room 016 can distribute electrical energy to various electrical devices. Different regions and different electrical devices have different power demands. The power distribution room 016, after converting electrical energy, distributes it to various users and areas through equipment such as power distribution cabinets. The power distribution room 016 can also control electrical energy; the switching equipment within it can control the on / off state of the circuit, thereby controlling the circuit's operating state and ensuring stable circuit operation.

[0063] In this embodiment, the battery transfer system 030 includes a vehicle assembly 200.

[0064] The two ends of the traveling component 200 are slidably connected to the top of the two support parts 110 respectively, and the traveling component 200 is provided with a lifting component 230.

[0065] In this embodiment, please refer to Figures 6-7 The traveling assembly 200 includes a traveling body 210 and a drive structure 220. At least two rollers 211 are provided at intervals at both ends of the traveling body 210. The drive structure 220 is disposed on the traveling body 210 and is used to drive the traveling body 210 to move along the guide rail 130.

[0066] In this embodiment, please refer to Figure 4 and Figure 8 The drive structure 220 includes a second drive member 221 and a drive shaft 222. The drive shaft 222 passes through both ends of the vehicle body 210 and is rotatably connected to the vehicle body 210. Gears 223 are provided at both ends of the drive shaft 222. The output end of the second drive member 221 is connected to the drive shaft 222 for transmission. Racks 224 are provided on the top of both support parts 110. The two gears 223 are respectively meshed with the racks 224.

[0067] Among them, rack 224 is located inside guide rail 130.

[0068] Of course, in some alternative embodiments, the drive structure 220 is not limited to the structure described above, and can also adopt a drive wheel scheme, chain scheme, belt scheme, etc. to realize the horizontal movement of the vehicle component 200.

[0069] In this embodiment, please refer to Figure 5 The vehicle assembly 200 is equipped with a proximity switch, and the top of the inner wall of the two support parts 110 is provided with multiple proximity switch sensors 150. Each battery position 013 is provided with three proximity switch sensors 150.

[0070] Understandably, when the positioning proximity switch on the vehicle assembly 200 senses the first proximity switch sensor, the vehicle assembly 200 decelerates; when the positioning proximity switch on the vehicle assembly 200 senses the second sensor, the vehicle assembly 200 has an accurate position relative to the battery 020, which facilitates the vehicle assembly 200 to lower the battery hanger 300 to grab the battery 020; the third sensor is used for deceleration during the return trip.

[0071] In this embodiment, the vehicle assembly 200 is provided with a positioning electric cylinder, and the inner wall of the roof 120 of the battery swapping box 100 is provided with a plurality of positioning holes spaced apart. The positioning electric cylinder and the positioning holes are located on the same horizontal line.

[0072] When the crane assembly 200 is not in use, the positioning electric cylinder is inserted into the positioning hole to ensure the crane assembly 200 is fixed.

[0073] In this embodiment, the battery transfer system 030 includes a battery hoist 300.

[0074] Among them, the battery lifting device 300 is used to hook the battery 020, and the battery lifting device 300 is connected to the lifting component 230, which is used to drive the battery lifting device 300 to move up and down.

[0075] In this embodiment, please refer to Figures 6-7 The crane body 210 is equipped with a lifting assembly 230, which includes a first drive member 231, four lifting drums 232 and four ropes 233. The output end of the first drive member 231 is connected to two lifting drums 232 on both sides respectively.

[0076] Furthermore, the battery lifting device 300 includes a lifting device body 310 and four lifting rollers 320. The four lifting rollers 320 are arranged at equal angles on the lifting device body 310 with the midpoint of the four lifting drums 232 as the center. The fixed ends of the four ropes 233 are fixed on the trolley body 210, and the movable ends of the four ropes 233 pass through the four lifting rollers 320 in sequence and are connected to the four lifting drums 232.

[0077] Understandably, the first drive unit 231 drives the four lifting drums 232 to rotate, and the four lifting drums 232 simultaneously wind the four ropes 233 so that the four ropes 233 drive the battery hoist 300 to move up and down simultaneously through the four lifting rollers 320.

[0078] Furthermore, the top of the lifting body 310 of the battery lifting device 300 is provided with at least two pins, and the bottom of the vehicle body 210 of the vehicle assembly 200 is provided with at least two mating sleeves. The at least two pins and the at least two mating sleeves are arranged opposite to each other and are connected in a mating manner.

[0079] Among them, at least two pins and at least two mating sleeves are connected to prevent the battery 020 from swinging during driving.

[0080] In this embodiment, the battery lifting device 300 further includes a first hook 330 and a second hook 340 disposed at the bottom of the lifting device body 310. The first hook 330 and the second hook 340 are provided in two sets, and the two sets of the first hook 330 and the second hook 340 are respectively located at both ends of the lifting device body 310. The first hook 330 and the second hook 340 can rotate and hook the frame 021 structure of the battery 020.

[0081] In this embodiment, the battery lifting device 300 further includes a third driving member, a moving rod, a first rotating rod, and a second rotating rod. The first rotating rod and the second rotating rod are rotatably mounted on the lifting device body 310 and vertically penetrate the lifting device body 310. The bottom of the first rotating rod is connected to the first hook 330, and the top of the first rotating rod is eccentrically connected to one end of the moving rod. The bottom of the second rotating rod is connected to the second hook 340, and the top of the second rotating rod is eccentrically connected to both ends of the moving rod. The third driving member is disposed on the top of the lifting device body, and the output shaft of the third driving member is rotatably connected to the moving rod. The third driving member is used to drive the first hook 330 and the second hook 340 to rotate.

[0082] The first hook 330 and the second hook 340 are initially facing the left or right side of the lifting device body 310, and the first hook 330 and the second hook 340 are parallel; the first hook 330 is in the open state facing the front side of the lifting device body 310; the second hook 340 is in the open state facing the rear side of the lifting device body 310.

[0083] The third driving component is equipped with a connecting rod, which is hinged to the output shaft of the third driving component.

[0084] Understandably, the third driving component extends the output shaft, which drives the first and second rotating rods to rotate eccentrically simultaneously. The eccentric rotation of the first rotating rod causes the first hook 330 to rotate from its initial state to face the front of the lifting device body 310; the eccentric rotation of the second rotating rod causes the second hook 340 to rotate from its initial state to face the rear of the lifting device body 310. Simultaneously, the eccentric rotation of the first and second rotating rods causes the first hook 330 and the second hook 340 to hook onto different upper beams of the battery 020's frame 021, thus achieving reliable hooking and positioning with the battery 020. Conversely, when the driving component retracts the output shaft, the first hook 330 and the second hook 340 retract, achieving reliable separation of the battery lifting device 300 from the upper frame 021 of the battery 020, allowing the battery lifting device 300 to detach from the battery 020.

[0085] In this embodiment, please refer to Figure 7 The bottom of the lifting device body 310 is provided with guide blocks 350. The guide blocks 350 have an arc-shaped structure and an outward-facing guide surface. It can be understood that, through the guide surface of the arc-shaped structure, the guide blocks 350 ensure that when the body is close to the battery 020, the guide surfaces of multiple guide blocks 350 correspond to and guide the upper frame 021 of the battery 020. This allows the battery lifting device 300 to be inserted into the top frame 021 of the battery 020 when there is a certain deviation between the positions of the vehicle assembly 200 and the battery 020, thus ensuring the precise positioning of the battery lifting device 300 and the battery 020.

[0086] In this embodiment, a positioning detection switch is provided on the top of the lifting device body 310. The positioning detection switch is used to detect whether the first hook 330 and the second hook 340 are in the open state. A contact rod is provided on the top of the first rotating rod and / or the second rotating rod. When the first hook 330 and the second hook 340 are in the open state, the contact rod contacts the positioning detection switch. By contacting the positioning detection switch with the contact rod, it can be determined whether the first hook 330 and the second hook 340 are fully opened.

[0087] The working principle and process of the battery transfer system 030 provided in this embodiment of the present invention are as follows:

[0088] Remove the undercharged battery 020 from the battery compartment 012: The lifting assembly 230 lowers the battery hoist 300 to the position, the battery hoist 300 opens the first hook 330 and the second hook 340 to hook the battery 020 from the battery compartment 012, the lifting assembly 230 raises the battery hoist 300 to the position, and the driving assembly 200 moves the battery hoist 300 and the battery 020 laterally to the first buffer position 014.

[0089] Replace with a fully charged battery 020: The driving component 200 moves the battery hoist 300 and battery 020 laterally to the second buffer position 015. The lifting component 230 lowers the battery hoist 300 into position. The battery hoist 300 opens the first hook 330 and the second hook 340 to hook the fully charged battery 020 on the second buffer position 015. The lifting component 230 raises the battery hoist 300 into position. The driving component 200 moves the battery hoist 300 and battery 020 laterally to the battery position 013 in the battery compartment 012.

[0090] In summary, the battery transfer system 030 provided by this utility model embodiment, by setting the battery compartment 012 at the bottom of the deck 011, can isolate each battery 020 individually in the battery position 013 set separately in the battery compartment 012, which facilitates independent fire protection. The fire protection system can meet the thermal runaway management of all batteries 020, making it safer than the existing battery transfer system 030. By setting up the battery swapping box 100, the trolley assembly 200 and the battery hoist 300, this application only needs to move in two directions to achieve battery swapping, which is one less direction of movement compared to the existing battery transfer system 030. The battery swapping time is reduced from 30 minutes to less than 20 minutes, improving the transfer efficiency of batteries 020. At the same time, the battery transfer system 030 with this setting has a simple structure and small size, leaving ample walking space on the deck 011.

[0091] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
