Title:
BATTERY PACK, AND ELECTRIC APPARATUS USING BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2019/106932
Kind Code:
A1
Abstract:
Provided is a battery pack that has an efficient arrangement of latch mechanisms provided on both the left and right sides by changing the arrangement direction of battery cells relative to a rail direction. A battery pack 30 has two parallel rails 38a, 38b provided in the front-rear direction in an upper case, the battery pack being attached/detached by being guided by rail grooves formed in an electric apparatus main body, and accommodating battery cells 56-58 inside a case such that the longitudinal axes of the battery cells match with a slide direction. Two latch buttons 60, 70 are provided on both the left and right sides of the upper case 31 and move in a direction that intersects with the slide direction. A height HL occupied by operation parts 62, 72 of the latch buttons 60, 70 is configured to partially overlap a height HB occupied by the battery cells 56-58 at a position in the up-down direction, thereby realizing a compact battery pack with a reduced total height H while keeping the size of the operation parts 62, 72 the same as conventional battery packs.
