Problems solved by technology

However, the structure of the bicycle frame is slightly complicated, and the folded model is still not compact and neat enough. Although the folded bicycle is greatly reduced in size, it cannot be pushed, and it still needs manpower to carry or carry it on the back, which cannot further reduce the rider's carrying. burden

Embodiment 1

[0049] Such as Figure 1 to Figure 4 A bicycle that can be promoted after the shown a small wheel diameter is vertically folded includes a front wheel 5, a front fork 4, a front fork riser 3, a handlebar frame, a vehicle frame, a rear wheel 19, a rear fork 14, a rear fork stand Pipe 15, vehicle seat and the drive mechanism that drives the wheel to rotate, wherein, the wheel diameter of front wheel 5, rear wheel 19 is identical, is 6 inch wheel, and front wheel 5 is installed in the front fork 4, and rear wheel 19 is installed in rear fork In 14, the handlebar frame includes a cross tube 1 and a stem tube 2, and the handlebar frame is connected by inserting the standpipe 2 into the front fork riser 3 for movable positioning, the height of the handlebar frame can be adjusted, the front fork 4, the front fork The fork stem 3 and the handle stem 2 are arranged from bottom to top, the front fork 4 is fixedly connected to the front fork stem 3, the front fork stem 3 is connected to ...

Embodiment 2

[0067] Such as Figure 5 to Figure 6 The shown pushable and liftable electric bicycle with a small wheel diameter that can be folded vertically is different from the first embodiment in that the driving mechanism is a combination of the pedal driving mechanism 18 and the motor driving mechanism, and the rear wheel 19 is replaced with an integrated motor. Wheel 26, increase the motor drive mechanism, the pedal drive mechanism 18 is installed in the middle part of the rear tube 12 of the vehicle frame, the pedal drive mechanism 18 is connected with the hub of the rear wheel 19 through the sprocket wheel; the motor drive mechanism includes a motor and power supply and control to the motor The battery and controller assembly 27 of the motor operation, the battery and the controller assembly 27 are installed on the rear fork standpipe 15, and the motor integrated wheel 26 is a built-in motor type rear wheel. The specific structure of the rear wheel is: the motor is installed on the ...

Embodiment 3

[0070] Such as Figure 7 to Figure 9 The pushable and liftable electric two-wheeled vehicle with small wheel diameter that can be folded vertically is different from embodiment two in that it does not use the pedal drive mechanism 18 and becomes a purely motor-driven electric vehicle.

[0071] The drive mechanism is a motor drive mechanism, and the motor drive mechanism includes a motor and a battery and a controller assembly 27 that supply power to the motor and control the operation of the motor. , for the built-in motor type rear wheel, the specific structure of the rear wheel is: the motor is installed in the inner diameter of the rear wheel tire and forms a whole with the rear wheel, the tire is installed on the motor rotor shell, and the motor directly drives the rear wheel tire to rotate. The front end of the front tube 10 of the vehicle frame is provided with two pedals 28 in total near the locking pin 23, which are used for placing both feet of the user when riding. ...

Abstract

The invention discloses a small wheel diameter pushable and liftable bicycle capable of being vertically folded. The bicycle comprises a front wheel, a rear wheel, a front fork, a rear fork, a front fork stand pipe, a handlebar rack, a bicycle frame, a saddle tube, a saddle seat and a driving mechanism, wherein the bicycle is integrally H-shaped; the front fork stand pipe and a handlebar vertical pipe are vertical, and the saddle tube is also vertical; a bicycle frame front tube and a bicycle frame rear tube are horizontally and transversely arranged to form one transverse line of the H-shaped bicycle; the bicycle frame front tube and the bicycle frame rear tube are hinged through a unidirectional rotation hinged joint positioned in the middle; the unidirectional rotation hinged joint rotates and is folded under the acting force of lifting; the bicycle is rectangle-shaped after being folded; after the bicycle is folded, the bicycle frame front tube and the bicycle frame rear tube are vertical, and the front wheel and the rear wheel are closed up and are positioned on the same straight line; after the bicycle is folded, the connecting line between the hinged shaft of the unidirectional rotation hinged joint and a front wheel axle and the connecting line between the hinged shaft of the unidirectional rotation hinged joint and a rear wheel axle form the two waists of an upright isosceles triangle. According to the bicycle, the structure of the overall bicycle can be simplified to the maximum extent, and the weight of the overall bicycle is reduced to the maximum limit.

Description

technical field [0001] The invention relates to a folding bicycle, in particular to a bicycle with a small wheel diameter that can be pushed after being folded vertically. Background technique [0002] Bicycle is an energy-saving and environment-friendly means of transportation. It used to be one of the main means of transportation in urban and rural areas of our country. At present, with the development of economy and technology, four-wheel motor vehicles and rail transit have already become the main means of transportation for people to go out in the city. Start getting people's favor. [0003] However, due to the increasing population density and the acceleration of the pace of life in cities, people prefer bicycles that are small in size and easy to carry. In addition to being suitable for short-distance driving, this bicycle is especially suitable for bicycles that cannot be covered by public transportation. For example, when traveling between a subway station or bus ...
