BATTERY PACK AND DEVICE USING BATTERY PACK

The embodiments of this disclosure provides a battery pack and a device using the battery pack. The battery pack includes: a battery module, including a plurality of secondary batteries and a module frame disposed on an outer periphery of the plurality of secondary batteries, wherein a lug is provided on a surface of the module frame away from the secondary batteries; and a fixing casing, comprising two fixing beams which are spaced apart and a limiting space which is located between the two fixing beams and used to accommodate the battery module, wherein a plurality of limiting holes which are spaced apart is provided on at least one of the fixing beams, and a clamping mechanism is disposed within the limiting hole to fix the lug between the clamping mechanism and the fixing beam. When the battery module is located within the limiting space, the lug on the module frame is fixed by a plurality of clamping mechanisms, and the plurality of clamping mechanisms are spaced apart, so the clamping operations among the plurality of clamping mechanisms will not be affected each other, facilitating the plurality of clamping mechanisms to fix different positions of the lug respectively; therefore the fixing effect of the clamping mechanism can be effectively improved, and the structural strength of the entire battery pack can be improved.
