Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a lithium battery pack with shock absorption performance. Background Art

[0002] Lithium battery is a primary battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. It is different from rechargeable lithium ion battery and lithium ion polymer battery. Due to the very active chemical properties of lithium metal, the rapid development of microelectronics technology at the end of the 20th century has led to an increasing number of miniaturized devices, which has put forward high requirements for power sources. Lithium batteries have entered a large-scale practical stage. Lithium ion batteries are a type of rechargeable battery, usually used in portable electronic products and electric vehicles. When lithium batteries are used in large electrical appliances, they usually appear in the form of lithium battery packs. At that time, lithium battery packs usually need to be moved with the electrical appliances during use, and are often affected by external vibrations. In severe cases, the lithium battery packs may be damaged and cannot be used normally.

[0003] In the prior art, the existing lithium battery packs are mostly directly installed in a box or a box body during use. Such lithium battery packs usually have no anti-protection device and have poor shock absorption performance. When impacted by the outside, the lithium battery pack is easily damaged and cannot work normally. Some lithium battery packs are provided with shock absorption devices, but they are usually fixed together with the lithium battery pack. When the lithium battery needs to be repaired and maintained, it needs to be disassembled as a whole and a large number of bolts need to be removed, which is a cumbersome process.

[0023] The shock absorbing assembly includes a shock absorbing plate 2, a damper 10, a second spring 11, a support pad 8, and a first spring 9. The shock absorbing plate 2 is arranged directly below the lithium battery pack box 1. The damper 10 is fixedly installed between the clamping member 7 and the shock absorbing plate 2. The upper end of the damper 10 is fixedly connected to the lower surface of the clamping member 7, and the lower end of the damper 10 is fixedly connected to the upper surface of the shock absorbing plate 2. The second spring 11 is sleeved on the outside of the damper 10, and the upper and lower ends of the second spring 11 are respectively fixedly connected to the clamping member 7 and the shock absorbing plate 2. The support pad 8 is arranged directly above the shock absorbing plate 2, and the upper surface of the support pad 8 is in contact with the lower surface of the lithium battery pack box 1. The first spring 9 is fixedly connected between the support pad 8 and the shock absorbing plate 2.

[0024] In this embodiment, by arranging a shock-absorbing component at the bottom of the lithium battery pack box 1, with the mutual cooperation of the shock-absorbing plate 2, the damper 10, and the second spring 11 of the shock-absorbing component, when the lithium battery pack box 1 is vibrated due to external influence, the damper 10 and the second spring 11 cooperate with each other to buffer and damp the external vibration, thereby reducing the influence on the lithium battery pack box 1, and further increasing the shock-absorbing performance of the overall device. The support backing plate 8 and the first spring 9 in the shock-absorbing component cooperate with the shock-absorbing plate 2, the damper 10, and the second spring 11 to further buffer and damp the lithium battery pack box 1, thereby further increasing the shock-absorbing performance of the overall device. By opening a clamping groove 101 on the outer surface of the lithium battery pack box 1 and clamping and fixing it through the clamping member 7, and at the same time setting the screw sleeve 3, the first bolt 4, and the second bolt 5 to freely change the distance between the two clamping members 7, it is convenient to clamp and fix or disassemble the lithium battery pack box 1, which not only increases the stability during clamping but also increases the convenience during the disassembly and assembly of the lithium battery pack box 1.

[0025] Specifically, a layer of rubber film 701 is adhesively connected to the inner surface of each clamping member 7.

[0026] Specifically, the clamping member 7 is in a "C" shape.

At this time, place the lithium battery pack box 1 between the clamping members 7, and at the same time, the lower surface of the lithium battery pack box 1 contacts the support backing plate 8, and make the positions of the clamping members 7 and the clamping groove 101 correspond. Then, rotate the screw sleeve 3 in the reverse direction to continuously reduce the distance between the two clamping members 7 until the lithium battery pack box 1 is stably clamped and fixed. When the lithium battery pack box 1 is vibrated due to external influence, with the mutual cooperation of the shock-absorbing plate 2, the damper 10, the second spring 11, the support backing plate 8, and the first spring 9 in the shock-absorbing component, the lithium battery pack box 1 can be effectively buffered and damped.
