Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a protective structure of a lithium battery pack. Background Art

[0002] With the continuous advancement of technology, there are more and more electronic devices. Nowadays, electronic devices are gradually becoming mobile. In order to achieve mobile use, lithium batteries are needed for power supply. For some devices with high power requirements, lithium battery packs are needed. In order to make the lithium battery pack stable, a protective structure is needed to fix it, so a special lithium battery pack protective structure is used;

[0003] The existing lithium battery pack protection structure often only has a protective shell on the outside of the lithium battery pack to protect the lithium battery pack from damage caused by external impact. However, when the protective shell is impacted, the lithium battery pack inside it will still be affected by the force generated by the impact, which may cause the battery core to heat up uncontrollably, or even catch fire and explode, causing very serious safety hazards. Therefore, we propose a protection structure for a lithium battery pack. Utility Model Content

The existing lithium battery pack protection structure often only has a protective shell on the periphery of the lithium battery pack to protect the lithium battery pack from damage caused by external impact. However, when the protective shell is impacted, the lithium battery pack inside it will still be affected by the force generated by the impact, which may cause the battery core to heat up uncontrollably, or even catch fire and explode, causing very serious safety hazards.

[0010] The technical effect of adopting the above further solution is that the entire structure can be made more stable through the fixed connection.

[0011] As a preferred solution of the present utility model, the buffer pad is made of sponge material.

[0012] The technical effect of adopting the above further solution is that the buffer pad made of sponge material has extremely high deformation ability and can effectively relieve the force generated by the impact.

[0013] As a preferred solution of the present invention, the bottom plate, top plate and side plates are all made of rubber material.

[0029] like Figure 1-3 As shown, a handle 102 is provided at the top of the shell cover 101, and an active lock 103 is provided between the front of the shell cover 101 and the protective shell 1.
