Center of gravity shifting forward and backward, speed control and seat rotating electric bicycle

Abstract

A gravity center front-back offset type speed controllable electric bicycle with a rotary saddle comprises axles, driving gears arranged on the axles and installing seats. Connecting plates are arranged at the bottom of the rear installing seat, foot rest plates are arranged on the outer sides of the lower ends of the connecting plates, driven gears are rotatably arranged on the installing seats, central shafts of the driven gears are rotatably connected to the installing seats, the connecting plates are provided with long slotted holes in the front-back directions, controllers are arranged in the long slotted holes, the inner ends of the central shafts are connected with angle sensors located in the long slotted holes, and the driven gears are meshed with the driving gears. A support arranged on the rear installing seat, the saddle located above the rear driving wheel is arranged on the support, a lithium battery is arranged at the bottom of the saddle, and a damp-supporting mechanism is arranged between a bicycle beam and the upper portion of the front side of the support. The gravity center front-back offset type speed controllable electric bicycle is good in flexibility, easy to operate, high in stability, good in safety and reliability and small in size and has a good control effect. A design structure of controlling the advancing speed based on gravity center is adopted, and the damp-supporting mechanism ensures that the saddle moves back and forth at a certain inclination angle and the bicycle does not fall over due to power loss.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to an electric bicycle with center of gravity offset front and rear, speed control and seat rotation. 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 no...

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
