[0029] As shown in Figures 1 to 4, the battery rack of this embodiment includes a frame 1 and a cable tie 3. The frame 1 is configured to support the battery pack. The cable tie 3 is detachably connected to the frame 1. The cable tie 3 includes a base 31 and at least two cable ties 32. The base 31 is detachably connected to the frame 1. All the cable ties 32 are spaced apart on the base 31 along a first direction (the X direction shown in the figure) and all the cable ties 32 extend along a second direction (the Y direction shown in the figure). The cable ties 32 are configured as connecting lines to the battery pack. The first direction and the second direction are set at an angle. The connecting lines of the battery pack include charging control lines, positive and negative terminal connecting lines, temperature control lines, and communication lines, etc., which are wires connected to external mechanisms. When a cable tie 3 is provided on each layer of the battery rack corresponding to a tray 2, the first direction is parallel to the vertical direction. When a cable tie 3 is provided on the top of the cable rack, the first direction and the second direction are perpendicular to the vertical direction.

[0030] By installing a wire-tying component 3 with a wire-tying rod 32 on the battery rack, the connecting wires of each battery pack can be connected to the wire-tying rod 32 and arranged along the length of the wire-tying rod 32, making the multiple connecting wires orderly and neatly arranged, facilitating later maintenance and easy locating; by setting multiple wire-tying rods 32 at intervals, different connecting wires can be connected to different wire-tying rods 32 at intervals, reducing interference between different connecting wires; by making the wire-tying component 3 detachable from the frame 1, it is easy to disassemble and assemble, and allows operators to select the number of wire-tying components 3 according to actual needs, reducing waste of wire-tying components 3, and also facilitating later maintenance, replacement or reuse.

[0031] As shown in Figure 4, each end of the binding rod 32 along the second direction is provided with a base 31, and the binding rod 32 and the base 31 are detachably connected. By detachably connecting the binding rod 32 and the base 31, the binding component 3 can be disassembled into two independent parts for production and then reassembled, reducing the production difficulty of the binding component 3 and reducing the maintenance cost when replacing the base 31 or binding rod 32 later. In this embodiment, two bases 31 are provided along the second direction, and the two bases 31 are respectively adjacent to the two ends of the binding rod 32 along the second direction to ensure the connection strength of the binding rod 32 and reduce the shaking of the end of the binding rod 32. One, two or more bases 31 are also provided between the two bases 31 to strengthen the support strength of the middle position of the binding rod 32.

[0032] As shown in Figure 5, the base 31 includes a main body 311, a snap-fit ​​portion 312, and a limiting portion 313. At least three snap-fit ​​portions 312 are spaced apart along a first direction on the main body 311. A snap-fit ​​groove 314 is formed between adjacent snap-fit ​​portions 312, and the cable tie 32 snaps into the snap-fit ​​groove 314. At least one of the two adjacent sides of two snap-fit ​​portions 312 protrudes and is provided with a limiting portion 313, which is configured to prevent the cable tie 32 from disengaging from the snap-fit ​​groove 314. The snap-fit ​​portions 312 form multiple snap-fit ​​grooves 314, allowing the cable tie 32 to be directly snapped into the snap-fit ​​grooves 314, which is convenient, quick, and easy to assemble and disassemble. By setting the limiting part 313, the wire tie rod 32 that is engaged in the engaging groove 314 can be effectively stopped, preventing the wire tie rod 32 from detaching from the engaging groove 314 and improving the installation stability of the wire tie rod 32; the base 31 has a simple structure, is easy to form in one piece, and is convenient to produce.

[0033] The spacing between two adjacent wire tying rods 32 is greater than 30mm. If the spacing is too small, it can easily cause interference between different connecting wires connected to the two wire tying rods 32. This spacing is reasonable, ensuring sufficient space for the connecting wires to be installed on the adjacent wire tying rods 32 and reducing interference between the connecting wires. In other embodiments, the wire tying rod 32 has a through hole, and the base 31 has a threaded hole. A bolt can be screwed through the through hole into the threaded hole, allowing for a detachable connection between the wire tying rod 32 and the base 31. The threaded connection is stable and easy to install and remove. Alternatively, the wire tying rod 32 can be directly welded to the base 31 to ensure the connection strength between the wire tying rod 32 and the base 31. In this embodiment, the base 31 has a slotted hole, and the frame 1 has a threaded hole. A bolt is passed through the slotted hole and screwed into the threaded hole to connect the base 31 and the frame 1, thus achieving a detachable connection between the wire tie 3 and the frame 1. The slotted hole facilitates adjustment of the base 31's position, and the threaded connection provides a secure connection and convenient assembly / disassembly. Alternatively, the base 31 can also be connected to the frame 1 using snap-fit ​​or other methods.

[0034] As shown in Figures 4, 5, and 6, the base 31 also includes a positioning part 315. The bottom of the snap-fit ​​groove 314 is provided with a protruding positioning part 315, and the outer periphery of the tie rod 32 is provided with a positioning hole 321. The positioning part 315 is inserted into the positioning hole 321. Through the cooperation of the positioning part 315 and the positioning hole 321, on the one hand, the installation position accuracy of the tie rod 32 can be improved, avoiding uneven lengths of each tie rod 32 protruding from the base 31, and improving the coordination and aesthetics of the overall structure of the tie member 3; on the other hand, the tie rod 32 can be a cylindrical rod, the snap-fit ​​groove 314 can be an arc-shaped groove, and the positioning part 315 inserted into the positioning hole 321 can effectively restrict the rotation of the tie rod 32, improving the connection stability of the tie rod 32. Of course, in other embodiments, it is not limited to setting the positioning part 315 on the main body part 311 and setting the positioning hole 321 on the outer periphery of the wire tying rod 32. Alternatively, the positioning part 315 can be set on the outer periphery of the wire tying rod 32, and the positioning hole 321 can be set on the main body part 311 and located between two adjacent snap-fit ​​parts 312.

[0035] As shown in Figure 6, the positioning hole 321 includes a guide hole 3211 and a connecting hole 3212. The guide hole 3211 is recessed on the outer periphery of the tying rod 32. The diameter of the guide hole 3211 gradually decreases along its depth direction. The connecting hole 3212 is opened at the bottom of the guide hole 3211, and the positioning part 315 is inserted into the connecting hole 3212. The guide hole 3211 guides the insertion of the positioning part 315, improving the connection between the positioning part 315 and the connecting hole 3212 and avoiding alignment difficulties, insertion difficulties, or even structural damage.

[0036] In some embodiments, as shown in Figures 1, 2, and 3, the battery rack further includes a tray 2 and a surrounding plate 4 detachably connected to the frame 1. Multiple trays 2 are spaced vertically on the frame 1, and multiple surrounding plates 4 are provided around the outer periphery of each tray 2. All the surrounding plates 4 around the outer periphery of each tray 2 enclose a mounting groove 5 for limiting the battery pack. The detachable connection of the surrounding plates 4 to the battery rack facilitates the installation and removal of the surrounding plates 4. At least one surrounding plate 4 should be installed with the battery rack after the battery pack is placed on the tray 2 to facilitate battery pack placement and reduce impact between the battery pack and the tray 2. The surrounding plates 4 have through holes, and the frame 1 has threaded holes. Bolts are passed through the through holes and screwed into the threaded holes to connect the surrounding plates 4 to the frame 1. This threaded connection method provides stable connection and convenient installation and removal. Alternatively, the surrounding plates 4 can be equipped with buckles, and the frame 1 can be equipped with slots, with the buckles engaging with the slots. Understandably, the enclosure 4 effectively protects and blocks the battery pack placed on the tray 2, preventing damage from external structural impacts or the battery pack from slipping off the tray 2, thus improving the safety of the battery pack on the tray 2.

[0037] As shown in Figure 2, the enclosure 4 includes a fixing part 41 and a stopping part 42. The fixing part 41 is detachably connected to the frame 1. The stopping part 42 protrudes from the fixing part 41 toward the battery pack side and is designed to prevent the battery pack from detaching from the mounting groove 5. By setting the stopping part 42, the top side of the battery pack can be effectively stopped, reducing the jumping of the battery pack and improving the installation stability of the battery pack.

[0038] In other embodiments, as shown in Figure 1, the battery rack includes at least two frames 1 and connectors. Adjacent frames 1 are detachably connected via the connectors. The connectors allow for the splicing of multiple frames 1 to form battery racks with different battery capacities, thus meeting the needs of different scenarios and improving the versatility of the battery racks. In this embodiment, the frames 1 have multiple threaded expansion holes spaced apart. The connectors have at least two rows of through holes. Bolts are passed through the through holes and screwed into the expansion holes to connect the connectors to the frames 1. The connectors connect adjacent frames 1 to complete the battery rack capacity expansion.

[0039] For example, as shown in Figure 1, the battery rack includes two frames 1. The edges of the two frames 1 are aligned. The connector includes a connecting piece, which connects to the expansion holes of the frames 1 to complete the installation of the battery rack consisting of the two frames 1. Furthermore, as shown in Figure 7, when the battery rack includes four frames 1, the connector includes a connecting piece, a connecting block 6, and a reinforcing connecting post 7. The four frames 1 are first divided into two frame groups, each frame group including two frames 1. The two frames 1 in each frame group are connected by the connecting piece. The two frame groups are spaced apart and opposite each other. The two frame groups are connected at the outermost edge of the frames 1 by the connecting block 6. A reinforcing connecting post 7 is provided in the spaced area between the two frame groups. The reinforcing connecting post 7 connects to the frame 1 in each frame group adjacent to the reinforcing connecting post 7 to strengthen the connection between the two frame groups. Of course, in other embodiments, depending on the actual application requirements, the battery rack can also include six, eight, or more frames 1.

[0040] The battery rack also includes a partition 8, which is detachably connected to the rack 1 and is located between two adjacent racks 1. By setting up the partition 8, the battery packs on two adjacent racks 1 can be effectively isolated, preventing the spread of flames in the event of a battery pack fire and improving the safety of the battery rack. Therefore, the partition can be made of a highly flame-retardant insulating board.

[0041] The tray 2 is equipped with a liquid cooling channel, which is connected to the external circulation mechanism via an inlet pipe and an outlet pipe. The inlet pipe and outlet pipe are tied to the cable tie 32. By integrating the liquid cooling structure into the tray 2, the structure not only supports the battery pack but also provides liquid cooling for it, reducing the need for traditional liquid cooling plates and thus minimizing their space occupation, effectively improving the space utilization of the battery rack. For example, the external circulation mechanism transfers coolant to the liquid cooling channel through the inlet pipe for heat exchange. After heat exchange, the coolant, having reached a certain temperature, is returned to the external circulation mechanism through the outlet pipe for further liquid cooling, thereby achieving continuous liquid cooling of the liquid cooling plate and ensuring the effective liquid cooling of the battery pack.

[0042] The battery rack also includes cable tie seats, with multiple cable tie seats spaced apart along the length of the cable tie rod 32. The cable tie seats facilitate fixed-point bundling of the connecting wires; that is, the connector can be secured to the cable tie seats using cable ties, reducing slippage of the cable ties and ensuring the stability of the connection position between the connecting wire and the cable tie rod 32. Alternatively, the connecting wire can be directly bundled to the cable tie rod 32 using cable ties to complete the connection. Furthermore, the connecting wire can be directly wrapped around the outer circumference of the cable tie rod 32.

[0043] The length of the wire tie rod 32 extends along the length direction of the connecting wire. The wire tie rod 32 guides the connecting wire along its length, making the layout of the connecting wires more organized and reducing clutter.
