Title:
FRAME OF ELECTRIC BICYCLE
Document Type and Number:
WIPO Patent Application WO/2018/099483
Kind Code:
A1
Abstract:
A frame of an electric bicycle, comprising a seat tube (12), a head tube (10), a top tube (9), a down tube (1), a bottom bracket shell (3), chain stays (7), a cylindrical battery (2), and a charging and discharging wire (5). The bottom bracket shell (3) is installed at the joint of the seat tube (12), the down tube (1), and the chain stays (7), and is provided with a battery mounting and removal opening (4) consistent and in communication with an inner hole of the down tube (1). The battery mounting and removal opening (4) is provided at and passes through a central axis through-hole (13) of the bottom bracket shell (3). The cylindrical battery (2) can be mounted or removed via the battery mounting and removal opening (4). A stopper block (6) is provided at an opening of the down tube (1) to limit the position of the cylindrical battery (2) in an axial and radial direction. The charging and discharging wire (5) has one end connected to both electrodes of the battery (2), and the other end led out via the battery mounting and removal opening (4) to be connected to a bicycle controller and a motor. An opening is provided at an upper portion of the down tube (1) to be a charging socket mounting opening (8). By designing a battery of an electric bicycle to have a cylindrical shape, and mounting the battery inside a down tube, the present invention optimally integrates the battery and a bicycle frame, enables easy mounting and removal of the battery, and simplifies a manufacturing process.
