[0048] See Figures 1 to 6As shown in the figure, this application provides a novel battery swapping system, including: a lower frame 1, a main frame 2, a lifting and mounting frame 4, a water-cooling unit 5, and multiple battery packs 3. A guide fitting is provided on the lower frame 1. The main frame 2 is located on top of the lower frame 1. The main frame 2 has multiple battery chambers and disassembly / removal ports 25 communicating with the battery chambers. The orientation of each disassembly / removal port 25 is perpendicular to the arrangement direction of the lower frame 1 and the main frame 2. Each battery pack 3 can be inserted into or removed from its corresponding battery chamber through its corresponding disassembly / removal port 25. The battery pack 3 is detachably connected to the main frame 2. The lifting and mounting frame 4 is connected to the main frame 2 and is located on the side of the main frame 2 opposite to the lower frame 1. The water-cooling unit 5 is disposed within the lower frame 1.

[0049] The battery system of this application supports quick installation and removal, enabling rapid power replenishment by replacing the battery system. A guide fitting part is provided on the lower frame 1, which can cooperate with the guide part on the battery base during transfer to the battery holder to achieve precise placement. The guide fitting part may include a base body and a guide groove provided on the base body. The guide part may be a guide post provided on the battery base. During the movement of the battery system from top to bottom, the guide post can be inserted into the guide groove, thereby guiding the battery system to accurately place on the battery base.

[0050] The battery swapping system of this application includes multiple battery packs 3, and multiple disassembly ports 25 are provided on the main frame 2. The opening of each disassembly port 25 is parallel to the horizontal plane, which makes it easy to install each battery pack 3 into the corresponding battery box through the disassembly port 25 or to remove the battery pack 3 from the battery cavity. Individual battery packs 3 are easy to disassemble and install, and convenient for maintenance and replacement.

[0051] Electrical connectors 6 are provided on the lower frame 1 of the novel battery swapping system. These connectors are electrically connected to each battery pack 3, and electrical connectors are also provided on the battery base. When the battery system is installed on the battery base, the two electrical connectors are electrically connected. A water-cooling unit 5 is at least partially disposed within the lower cavity of the lower frame 1, and is connected to the cooling pipes within the battery packs 3. The battery box of this application places the water-cooling unit 5 within the lower cavity, making full use of the space in the lower frame 1. An integrated PDU can be installed on the lower frame 1, and the electrical connectors 6 can be integrated onto the integrated PDU.

[0052] The electrical connector 6 is located in the middle of the lower frame 1. The water-cooled unit 5 typically includes a condenser, water pump, compressor, etc. In this application, the various components of the water-cooled unit 5 are distributed in the lower cavity, and each component is located on both sides of the electrical connector 6. This makes full use of the space on both sides of the electrical connector 6 and avoids the problem of occupying a large space by placing the water-cooled unit 5 on the top of the main frame 2. This results in a smaller overall height and volume of the battery box, a reasonable and compact distribution of the various modules of the entire battery system, and good structural stability of the battery system.

[0053] In some possible implementations, the main frame 2 includes two first side panels 23, two frame bodies 21, and multiple support plates 22. The two frame bodies 21 are spaced apart and arranged in parallel. Each support plate 22 is disposed between the two frame bodies 21. The support plates 22 are arranged sequentially at intervals along the height direction of the frame bodies 21. Each support plate 22 is connected to the two frame bodies 21. The two first side panels 23 cover the two frame bodies 21 respectively. The battery cavity and the disassembly / removal port 25 are formed between two adjacent support plates 22 and two first side panels 23.

[0054] The main frame 2 has multiple disassembly ports 25 on its opposite sides, through which each battery pack 3 is inserted into or removed from its corresponding battery cavity. The battery pack 3 can be installed into its respective battery cavity using a side-push method. This application employs a distributed water-cooled unit 5 and a side-push pack assembly structure, ensuring a compact system layout while also facilitating after-sales maintenance.

[0055] In some possible implementations, the main frame 2 includes two second side panels 24, which are detachably connected to the frame body 21 to respectively close or open a plurality of disassembly ports 25 on the corresponding side of the main frame 2. The two second side panels 24 are easy to assemble and disassemble, and after the second side panels 24 are disassembled, each disassembly port 25 is directly exposed, making it convenient to remove or install the battery pack 3.

[0056] In some possible implementations, the second side panel 24 is provided with a connecting hole, and the frame body 21 has a threaded hole. The stud of the bolt passes through the connecting hole and is threaded into the corresponding threaded hole, and the bolt head is confined to the second side panel 24. A rivet nut with a threaded hole can be provided on the column 211 at the end of the frame body 21 for easy connection of the bolt.

[0057] In some possible implementations, the frame 21 includes a plurality of columns 211, with crossbeams 212 connecting adjacent columns 211. The battery pack 3 is connected to an adapter 31, which extends to the crossbeams 212 when the battery pack 3 is installed in the battery cavity. The adapter 31 and the crossbeams 212 are detachably connected by fasteners.

[0058] Each battery pack 3 is connected to the corresponding crossbeam 212 by fasteners passing through the adapter 31. When disassembling the battery pack 3, only the fasteners need to be removed to take out the battery pack 3.

[0059] In some possible implementations, the adapter 31 is located on the side of the crossbeam 212 away from the lower frame 1. The fastener includes a screw and a cap disposed on the screw. The crossbeam 212 is provided with a threaded hole. The screw of the fastener passes through the adapter 31 and is threadedly connected to the crossbeam 212. The cap of the fastener is confined within the adapter 31.

[0060] The cap is positioned at the top of the adapter 31, and the fasteners are installed on the crossbeam 212 from top to bottom to secure the adapter 31 to the crossbeam 212. When it is necessary to remove the battery pack 3, the fasteners are rotated in the opposite direction to unscrew them upwards, thereby disengaging the battery pack 3 from the crossbeam 212.

[0061] See Figure 6 As shown, the adapter 31 may include a strip beam 311 and a plurality of extension pieces 312 located on the strip beam 311. Each extension piece 312 is arranged sequentially at intervals along the length direction of the strip beam 311. The strip beam 311 can be connected to the battery pack 3 by fasteners. Each extension piece 312 can extend to the crossbeam 212 respectively. Each extension piece 312 may be provided with a connection hole, so that one end of the fastener can pass through and be threadedly connected to the crossbeam 212.

[0062] In some possible implementations, the crossbeam 212 has an upper plate 2121, a lower plate 2122, and a connecting plate connecting the upper plate 2121 and the lower plate 2122. The upper plate 2121 and the lower plate 2122 are spaced apart. The support frame 22 includes multiple central support beams 221, with both ends of each central support beam 221 inserted between the upper plate 2121 and the lower plate 2122 of the corresponding crossbeam 212. This enhances the structural strength of the crossbeam 212.

[0063] In some possible implementations, the support frame 22 includes end support beams 222, which are located at both ends of each of the middle support beams 221. The two ends of the end support beams 222 are respectively connected to the two frame bodies 21. Weight reduction grooves 2221 are provided on the end support beams 222, thereby achieving lightweight design while meeting the structural strength requirements.

[0064] In some possible implementations, the end support beam 222 is provided with a restraint hole 2222, the restraint member has a collar and a connector for connecting the collar, the connector is inserted into the restraint hole 2222, and the collar is sleeved on the cable or cooling water pipe connecting the battery pack 3.

[0065] The hoisting support frame 4 is connected to the top of the main frame 2 and can be used to cooperate with hoisting equipment to provide hoisting points and facilitate connection with the hoisting equipment's lifting gear.

[0066] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
