Abstract

The invention provides a battery pack, which comprises a bare cell, a support member positioned at the top of the bare cell and a top case that covers the support member. In the battery pack, a protruding portion is formed in an end of the support member, and a receiving portion is formed at a position corresponding to the protruding portion in the top case. Accordingly, the protruding portion is inserted into the receiving portion, so that it is possible to provide the battery pack to be stronger against external impact.

Description

technical field [0001] One aspect of the invention relates to a battery pack. Background technique [0002] Recently, battery packs have been variously used as power sources of portable electronic devices. As portable electronic devices are used in various fields, demands for battery packs are rapidly increasing. The battery pack is capable of being charged / discharged many times, and thus is economically and environmentally efficient. Therefore, the use of battery packs is encouraged. [0003] As the use of smartphones increases, battery packs are developed to increase the capacity of the battery pack. The increase in the capacity of the battery pack is linked to the increase in the weight of the battery pack, which causes problems including damage to the case, denting of the battery pack, and the like. Contents of the invention [0004] The embodiment provides a battery pack that is highly resistant to external impacts by adopting a new structure. [0005] According ...
