Problems solved by technology

[0002] In the prior art, a bicycle includes a frame body, a first wheel arranged at the lower part of the frame body, a saddle arranged at the upper part of the frame body, and is used to drive the first wheel to rotate The driving mechanism of this single-wheeled bicycle constitutes a single-wheeled bicycle. Since only the first wheel of this single-wheeled bicycle is in contact with the ground surface, when a person rides on this single-wheeled bicycle, the bicycle and the human body may fall forward at the same time. It is possible to fall backwards, to the left, or to the right, so this kind of single-wheeled bicycle is difficult and not safe enough to ride

Embodiment Construction

[0015] As attached figure 1 As shown, a bicycle includes a frame body 1, a first wheel 2 arranged on the lower part of the frame body 1, a saddle 3 arranged on the upper part of the frame body 1, and used for driving the The driving mechanism 5 for rotating the first wheel 2 further includes a wheel assembly 8 arranged at the lower part of the frame body 1, and the wheel assembly 8 is located in front of the first wheel 2. As attached figure 2 As shown, the wheel assembly 8 includes a wheel joint 7 rotatably arranged at the lower part of the frame body 1 through a first rotating shaft 9 and a wheel joint 7 rotatably arranged at the lower part of the frame body 1 through a second rotating shaft 10. For the second wheel 6 on the 7th, the axis of rotation of the second wheel 6 is spatially perpendicular to the axis of rotation of the wheel joint 7. The axis of rotation of the second wheel 6 is parallel to the horizontal plane. The axis of rotation of the wheel joint 7 extends substa...

Abstract

The invention discloses a bicycle, which comprises a frame, the first wheel at the lower part of frame, a bicycle saddle at the upper part of frame, the driving device for rotating the first, and the wheels at the lower part of frame. Wherein, the wheels at the front of the first wheel; the wheels comprises a wheel connector rotationally mounted at the lower part of frame and the second wheel rotationally mounted at the wheel connector, whose axle of rotation axle is vertical to the axle of rotation axle of wheel connector. Since the second and first wheels are mounted at the front and back of frame, and they are all contacted with the ground, it can avoid driver incline, and the second wheel can be rotated left or right via the wheel connector, only when people controls the gravity center rightwards or leftwards, therefore, people can drive the bicycle stably.

Description

Technical field [0001] The invention relates to a bicycle. Background technique [0002] In the prior art, a bicycle includes a frame body, a first wheel arranged on the lower part of the frame body, a saddle arranged on the upper part of the frame body, and used to drive the first wheel to rotate. The driving mechanism of the single-wheeled bicycle constitutes a single-wheeled bicycle. Since this single-wheeled bicycle only has the first wheel in contact with the ground surface, when a person rides on this single-wheeled bicycle, the bicycle and the human body may fall forward at the same time. It is possible to fall backward, fall to the left, or fall to the right. Therefore, this kind of unicycle is difficult and not safe enough to ride. Summary of the invention [0003] The purpose of the present invention is to provide a bicycle that is easier to ride and relatively safe. [0004] The technical solution of the present invention is: a bicycle comprising a frame body, a first...
