Especially in the new energy vehicle market, high energy density and lithium battery modules have become key requirements, and the types of batteries are becoming increasingly diverse, including lithium batteries, hydrogen batteries, alkaline batteries, acid batteries, etc. Among them, lithium batteries have been widely used in many fields due to their advantages such as high energy density and long cycle life.

[0003] The prior art patent document with publication number CN220627996U provides a lithium battery module, which utilizes a combination of three components: a support component, a fixing component, and a heat dissipation component, and is matched with a support base plate. The limiting groove on the top of the support base plate controls and fixes the battery cell, and the battery cell cooperates with the heat dissipation component to work.

[0004] Although the lithium battery has many beneficial effects, the following problems still exist: the lithium battery is used to work inside various machines and will experience vibrations during the working process. Since the lithium battery is not fixed enough, the lithium battery will be misplaced or offset during the internal vibration, resulting in abnormal use and poor stability. In addition, the lithium battery will generate heat inside when in use, and there is no heat dissipation device inside. Because the lithium batteries are close together, the heat is too high. The high heat will make the overall use unstable and unsafe. Utility Model Content

The side fixing plate 120 and the top plate 130 support the entire lithium battery, and can also prevent some debris and rainwater from entering the interior.

[0032] The fixing assembly 200 includes a battery cell 210 disposed on the inner wall of the limiting groove 111 , and a clamping ring 220 is disposed on the circumferential outer wall of the battery cell 210 .
