AI Technical Summary
Technical Problem
Existing battery packs are prone to damage or explosion and combustion when subjected to external forces or impacts, posing a safety hazard.
Method used
A protective device is designed, including a protective box, a collection compartment, and a buffer mechanism. It utilizes first and second elastic elements, a buffer plate, and a buffer strip to provide elastic buffering in multiple directions. The protective box has a buffer space to reduce the impact of collisions on the battery pack.
Benefits of technology
It effectively prevents the battery pack from being damaged or exploded under impact or external force, improving safety, and the battery pack can be easily picked up and put down through the limiting mechanism.

Abstract
This application discloses a protective device and a battery module, solving the technical problem in the prior art where valuable items are easily damaged when subjected to external forces or impacts. The protective device includes a protective box, a collection compartment, and a buffer mechanism. The protective box has a protective cavity; the collection compartment is movably disposed within the protective cavity and has several mounting slots for placing objects; the buffer mechanism is movably installed within the protective box and includes a first elastic member, a second elastic member, buffer strips, and a buffer plate. The first elastic member acts on the buffer plate to provide elastic buffering in a first direction; two or more buffer strips are located on the upper and lower sides of the collection compartment and are slidably connected to the collection compartment in a second direction perpendicular to the first direction; the second elastic member acts on the buffer strips to provide elastic buffering in a third direction perpendicular to both the first and second directions. This application uses a buffer mechanism to cushion the protective box, reducing the force on the collection compartment.
