A vertical motion battery latching mechanism for a power equipment having a removable battery can include a central lever, a latch button and a vertically pushed button. The central lever can be configured to rotate about an axis. The latch button can be vertically movable by rotation of the central lever and configured to selectively secure and release the battery with respect to the power equipment. The latch button can be biased toward securing the battery onto the power equipment. The vertically pushed button can rotate about a second axis different from the first axis and be configured to contact the central lever to rotate the central lever about the first axis and release the battery from the power equipment by moving the latch button vertically.

A locking mechanism for a battery pack. The locking mechanism comprises a fixing piece, the fixing piece being provided with a locking space. When the battery pack is placed relative to the bracket, the locking mechanism is used to lock a connecting rod on the battery pack. The locking mechanism is provided facing the battery pack on a side of the locking space and is close to an opening of the battery pack in the vertical direction so that the connecting rod enters the opening along the vertical direction facing the bottom wall of the bracket and moves into the locking space. Thus, the complexity process of installing and fixing a battery pack are effectively reduced, and the reliability of fixation is also ensured. Also provided are a bracket assembly, an electric vehicle and a locking method for a battery pack.

Embodiments are described providing efficient ways for housing batteries in electrically driven vehicles. In particular, a vehicle chassis is described comprising an internal cavity for holding one or more batteries. The batteries can be mounted within the chassis cavity and held on rails, allowing the batteries to extend out of the chassis cavity on the rails for servicing and removal/replacement. In various embodiments, the chassis cavity can be separated into sub-compartments by one or more partition walls running lengthwise along the chassis inside the cavity. Each sub-compartment can hold a separate battery similarly mounted on rails, allowing each battery to extend out of the chassis cavity individually.
