An electric bicycle whose speed is controlled by the position of the center of gravity

Abstract

An electric bicycle with the running speed controlled through the centre-of-gravity position comprises an axle, a driving gear arranged on the axle, and an installation base; a connection plate is arranged on the bottom of the installation base, pedals are arranged on the outer side of the lower end of the connection plate, the installation base is provided with a driven gear, and a center shaft of the driven gear is connected to the installation base in a rotating mode; a long slotted hole is formed in the front-back direction of the connection plate, a controller is arranged inside the long slotted hole, and the inner end of the center shaft is connected to an angle sensor located inside the long slotted hole; the driven gear and the driving gear are meshed; the installation base is provided with a support, a saddle located above a driving wheel is arranged on the support, a lithium battery is arranged on the bottom of the saddle, and a damping supporting mechanism is arranged between a bicycle beam and the upper part of the front side of the support. The electric bicycle has the advantages that the flexibility is good, the operation is easy, the stability is high, the safe reliability is high, the size is small and the control effect is good; by adopting the design structure of controlling the running speed through the centre of gravity, the damping supporting mechanism can guarantee that the saddle can move by a certain inclination angle in the front-back direction and cannot be tumbled because of power loss.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to an electric bicycle whose driving speed is controlled by the position of the center of gravity. Background technique [0002] In recent years, electric bicycles have become an indispensable means of transportation for ordinary people in our country. However, due to the relatively large size of electric bicycles and the lack of flexible steering, it is difficult to use them in places with dense crowds, traffic or narrow spaces. Ride normally. In recent years, with the continuous improvement of the urban public transport system, many people have begun to consider using this light electric vehicle for short-distance transportation from home to the bus station and transfer transportation in the public transportation system. There are many self-balancing electric vehicles on the market, but the structure of the existing self-balancing electric vehicles is relatively complicated, and it is not v...

Problems solved by technology

There are many self-balancing electric vehicles on the market, but the structure of the existing self-balancing electric vehicles is relatively complicated, and it is not very easy to operate when driving, and most of them can only be operated standing up. Driving for a long time will be tiring
