Technical Field

[0001] This utility model relates to the field of lithium battery assembly rack technology, specifically a low-temperature resistant lithium battery assembly rack. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Currently, lithium batteries need to be installed on lithium battery racks during use, so people usually stack multiple lithium batteries together using racks.

[0003] Chinese Patent Publication No. CN209607800U discloses a lithium battery assembly rack, including a base frame and an extension frame slidably connected inside the base frame. The base frame has symmetrically arranged sliding grooves inside, and the extension frame is placed in a cavity between two of the sliding grooves. The extension frame and the sliding grooves are slidably connected by a slider. A lithium battery mounting plate is fixed to the upper surface of both the base frame and the extension frame. The lithium battery assembly rack consists of a base frame and an extension frame, with the extension frame housed inside the base frame. When it is necessary to increase the discharge power of the lithium battery pack, the extension frame is pulled out of the base frame by sliding the slider on the sliding grooves, and lithium batteries are installed on the lithium battery mounting plate of the extension frame, increasing the specifications of the lithium battery pack and thus improving the discharge power. The extension frame's pulling length can be adjusted according to usage needs to install different numbers of lithium batteries, reducing the time and cost investment in custom-made lithium battery racks.

[0004] Most existing technical solutions have the following drawbacks: they do not have good heat preservation function for the lithium battery body, resulting in poor low-temperature resistance of the lithium battery body. At the same time, the installation stability of the lithium battery body is poor, making it prone to loosening. Therefore, this utility model provides a low-temperature resistant lithium battery assembly frame to solve the above-mentioned problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a technical solution: a low-temperature resistant lithium battery assembly frame, including a mounting base 1, a support frame 2 fixedly installed on the outer side of the lower end of the mounting base 1, and a lithium battery body 4 placed inside the mounting base 1. It also includes baffles 3 for separation that are fixedly installed at equal intervals inside the mounting base 1, and a first heat insulation plate 5 located below the lithium battery body 4 is provided at the lower end of the interior of the mounting base 1. Fixing plates 6 are installed on the outer sides of both the front and rear ends of the mounting base 1 by screws, and support blocks 7 located inside the mounting base 1 are fixedly installed on the outer side of the fixing plates 6. Prefabricated through slots 8 adapted to the support blocks 7 are opened through the interior of both the front and rear ends of the mounting base 1. Simultaneously, the mounting column 9 is integrated and fixedly installed at the top corner of the mounting base 1, and a fixing bolt 10 is provided inside the upper end of the mounting column 9. A fixed top plate 11 is provided on the upper outer side of the lithium battery body 4, located above the mounting base 1. A positioning column 12 is fixedly installed at the lower top corner of the fixed top plate 11. A second insulation board 13 is pasted on the inner side of the fixed top plate 11, and a limiting block 14, also located on the inner side of the fixed top plate 11, is provided on the outer side of the second insulation board 13. Threaded holes 15 that are compatible with the fixing bolt 10 are opened inside the mounting column 9 and the fixing bolt 10. Together, they form a low-temperature resistant lithium battery assembly frame.

[0018] When using this low-temperature resistant lithium battery assembly rack, specific details are as follows: Figure 1 and Figure 2 As shown, firstly, the mounting base 1 is stably placed on the designated plane using the support frame 2, and the position of the support frame 2 is fixed with screws. Then, the lithium battery body 4 is placed into the space between the mounting base 1 and the baffle 3, combined with... Figure 4 As shown in the figure, at this time, the lower end of the lithium battery body 4 is in contact with the support block 7 which is fixedly installed in the mounting base 1 by the fixing plate 6 and screws, so that the support block 7 is distributed at the lower corner of the lithium battery body 4. At this time, the support block 7 has a good supporting effect on the lithium battery body 4. Similarly, the remaining lithium battery bodies 4 are assembled and installed in the mounting base 1 according to the above steps. Specific examples Figure 1 and Figure 3As shown, since the positioning post 12 and the mounting post 9 are arranged in a one-to-one correspondence and are connected by a plug-in method, after installation, the fixing top plate 11 is installed on the upper outer side of the lithium battery body 4. At this time, the positioning post 12 is inserted into the interior of the mounting post 9. Then, the positioning post 12 is rotated and inserted into the interior of the mounting post 9 and the positioning post 12 in sequence, so that the fixing bolt 10 can be threadedly connected and fixed to the mounting post 9 and the positioning post 12 through the threaded hole 15 respectively. This makes it easy to fix the fixing top plate 11 on the upper outer side of the lithium battery body 4. Since the upper side of the lithium battery body 4 is connected to the limiting block 14, and the longitudinal section of the lithium battery body 4 is an "L" shaped structure, the limiting block 14 can be connected to the side of the lithium battery body 4 under the action of the fixing top plate 11. This makes the limiting block 14 improve the installation stability of the lithium battery body 4 and prevent it from loosening. Combination Figure 5 As shown, the second insulation plate 13 can be located directly above the lithium battery body 4, so that the first insulation plate 5 and the second insulation plate 13 have a good heat preservation function for the lithium battery body 4, which helps to improve the low temperature resistance of the lithium battery body 4. This is the usage method of the low temperature resistant lithium battery assembly frame.
