Problems solved by technology

[0003] Due to the compact structure of the battery packs currently on the market, the size of the adapter part is usually made relatively small due to the limited space layout of the battery pack, and the connection between the battery pack and the electric tool or charger is not stable enough. It is easy to cause the connection to fail

Abstract

The present invention relates to a battery pack, which comprises: a battery pack case; and a battery cell group which is arranged in the battery pack case and comprises a plurality of electrically connected battery cells; the battery pack further comprises an adaptation part used for being connected with external equipment in the sliding direction, the adaptation part is arranged on the side portion of the battery pack case and comprises a pair of sliding rails or sliding grooves extending in parallel in the sliding direction, and the distance between the pair of sliding rails or sliding grooves is defined as a first width; the outermost boundary of the side portion has a second width perpendicular to the sliding direction, and the ratio of the first width to the second width is between 0.47 and 0.52. The battery pack has the beneficial effects that the size of the battery pack adaptation part is proportionally coordinated with the size of the battery pack, so that the requirement of small overall size of the battery pack can be met, and the stable connection between the battery pack and external equipment can be ensured.

Description

technical field [0001] The invention relates to a battery pack. Background technique [0002] The battery pack is generally detachably connected to the electric tool or the charger. The battery pack has an adapter that matches the electric tool or the charger. The adapter is used to mechanically and electrically connect the battery pack to the electric tool or the charger. The locking structure locks the battery pack on the electric tool. [0003] Due to the compact structure of the battery packs currently on the market, the size of the adapter part is usually made relatively small due to the limited space layout of the battery pack, and the connection between the battery pack and the electric tool or charger is not stable enough. It is easy to cause connection failure. Contents of the invention [0004] In order to overcome the defects of the prior art, the problem to be solved by the present invention is to provide a battery pack with a compact structure and a stable c...
