Power battery pack device convenient for changing installation position

Abstract

The invention provides a power battery pack device with facilitation of changing installation direction and position. The power battery pack device comprises a main body (1) and a suspension assembly arranged on the back surface of the main body (1). The suspension assembly comprises a fixed seat (2) fixedly connected with a vehicle frame, a coupled seat (3) and a locking device (5) mounted on the coupled seat (3). The coupled seat (3) is provided with a fixed seat engagement part (31) which is detachably connected with the fixed seat and a main body slicing part (32) which is connected with the main body (1). The installation direction and position of the main body (1) can be changed by determining the fixing position of the fixed seat (2) on the vehicle frame. The locking device (5) is used to lock the main body (1) on the suspension assembly. The installation direction and position of the power battery pack device are easy to change according to the requirement. The power battery pack device is widely used in powder devices such as electric bicycles.

Description

technical field [0001] The invention relates to a power supply device, in particular to an installation structure of a battery pack device for powering an electric bicycle. Background technique [0002] Most of the power battery packs of existing electric bicycles are installed on the front beam of the bicycle or the rear standpipe of the vehicle frame. For example, some are obliquely fixed on the rear standpipe of the vehicle frame. After the power battery is assembled, the battery pack and the box-type device are fixedly connected together with screws from the bottom of the box-type device; Finally, fix the battery pack with screws from the bottom of the frame. The above installation structure of the battery pack limits the installation position of the battery pack, so that it can only be installed on a fixed position of the vehicle frame such as the rear riser, and the installation of the battery pack at this position not only takes up the limited space between the vehic...
