Abstract

The utility model discloses a battery bag, comprising a housing, an electric battery group, an upper plate and a lower plate arranged in the inner cavity of the housing. The electric battery group is clamped between the upper plate and the lower plate and is contained in the housing. An elastic cushion is provided between the housing and the upper plate or between the housing and the lower plate. The electric battery group is tightly maintained in the housing through the elastic deformation of the elastic cushion to prevent the failure of the connection point resulting from the swinging of the electric battery group.

Description

Power brick

Technical field

The utility model relates to a kind of power brick, refers to a kind of power brick that prevents that battery pack from rocking in the enclosure especially.

Background technology

Existing power brick generally is made of last plastic casing, following plastic casing, train wheel bridge, lower plate, imbibition pad and battery pack, battery pack is sandwiched between between the upper and lower clamping plate, wherein, be provided with the imbibition pad between lower plate and the battery pack, to draw the liquid that battery pack spills, train wheel bridge, battery pack, imbibition pad, lower plate integral body are contained in the plastic casing.The height of receiving space is greater than the height summation of clamping plate and battery pack in the general housing, doing something in disregard of obstacles when preventing to install relates to, yet this existence that surplus is installed teetertotters battery easily in the enclosure, thereby may cause the fracture of contact place, power brick was lost efficacy.

Summary of the invention

The purpose of this utility model is to provide a kind of power brick that prevents that battery from rocking in the enclosure, to improve the use reliability of power brick.

The purpose of this utility model is achieved in that a kind of power brick, comprise shell, battery pack, be arranged at train wheel bridge and lower plate in the shell inner cavity, described battery pack is folded between train wheel bridge and the lower plate, it also comprises at least one cushion, and described cushion is arranged between shell and the lower plate or between shell and the train wheel bridge.

The utility model compared with prior art has following advantage: alleviate even eliminate battery pack rocking in power brick, prevent that the contact place from damaging, and improves the security reliability of power brick greatly.
