Abstract
The present invention relates to a bicycle which comprises a bicycle frame body, a first wheel arranged on the lower part of the bicycle frame body, a bicycle saddle arranged on the upper part of the bicycle frame body, a drive mechanism used for driving the first wheel to rotate, and a wheel component arranged on the lower part of the bicycle frame body, wherein the wheel component is positioned in the front of the first wheel; the wheel component comprises a wheel joint arranged on the lower part of the bicycle frame body in a rotating mode, and a second wheel arranged on the wheel joint in a rotating mode; the rotating axial lead of the second wheel is vertical to the rotating axial lead of the wheel joint in a space mode. Because the front and the back parts of the lower part of the bicycle frame body are provided with the second wheel and the first wheel, the first wheel and the second wheel both contact the ground, and that a person falls down forwards or backwards when riding the bicycle is avoided. At the time of riding, as long as a human body controls the own gravity center left or right, the second wheel rotates left or right under the action of the wheel joint, and the person can smoothly, easily and safely ride the bicycle.
Description
Technical field
The present invention relates to a kind of bicycle.
Background technology
In the prior art, bicycle, comprise the vehicle frame body, be arranged on first wheel of described vehicle frame body bottom, be arranged on the saddle of described vehicle frame upper part of body, be used to drive the driver train of described first wheel, thereby formation unicycle, because this unicycle has only first wheel to contact with ground surface, when the people rides when sailing on this unicycle, bicycle and human body might fall down forward simultaneously, might fall down backward, might fall down left, also might fall down to the right, thereby this unicycle is ridden when sailing difficult, safety inadequately.
Summary of the invention
The object of the invention provides bicycle, sails and comparatively safe than being easier to ride.
Technical scheme of the present invention is: a kind of bicycle, comprise the vehicle frame body, be arranged on first wheel of described vehicle frame body bottom, be arranged on the saddle on described vehicle frame body top, be used to drive the driver train of described first wheel, also comprise the wheel assembly that is arranged on described vehicle frame body bottom, be arranged on the grab rail on the described vehicle frame body, described wheel assembly is positioned at the place ahead of described first wheel, described wheel assembly comprises the wheel joint that is arranged on described vehicle frame body bottom by first turning cylinder rotationally, be arranged on described second wheel of taking turns on the joint rotationally, the rotational axis line of described second wheel is vertical with described rotational axis line phase space of taking turns joint, by control human body self center of gravity, under the described effect of taking turns joint, make described second wheel rotate to the left or to the right.
Described grab rail is positioned at the place ahead of described saddle.
The top of described grab rail is provided with handlebar.
Described second wheel has two, and described two second wheels are arranged on described both sides of taking turns joint respectively rotationally.
Have tube chamber on described vehicle frame body, the described parts of taking turns in two parts of joint, and being inserted in rotationally in the described tube chamber to small part of another parts.
The wheel diameter of described second wheel is less than the wheel diameter of described first wheel.
The rotational axis line of described second wheel parallels with horizontal surface.
The present invention compared with prior art, has following advantage: owing to tandem second wheel and first wheel of being provided with in the bottom of described vehicle frame body, first wheel all contacts with ground surface with second wheel, fall down forward or fall down backward when having avoided the people to ride sailing on vehicle, ride when sailing, human body only need be controlled self center of gravity to the left or to the right, under the described effect of taking turns joint, make described second wheel rotate to the left or to the right, thereby the people just can ride reposefully and sail bicycle, rides when sailing that ratio is easier to and comparatively safe.

The specific embodiment
As shown in Figure 1, a kind of bicycle, comprise vehicle frame body 1, be arranged on described vehicle frame body 1 bottom first wheel 2, be arranged on described vehicle frame body 1 top saddle 3, be used to drive the driver train 5 that described first wheel 2 rotates, also comprise the wheel assembly 8 that is arranged on described vehicle frame body 1 bottom, described wheel assembly 8 is positioned at the place ahead of described first wheel 2.As shown in Figure 2, described wheel assembly 8 comprise by first turning cylinder 9 be arranged on rotationally described vehicle frame body 1 bottom wheel joint 7, be arranged on described second wheel 6 of taking turns on the joint 7 rotationally by second turning cylinder 10, the rotational axis line of described second wheel 6 is vertical with described rotational axis line phase space of taking turns joint 7.The rotational axis line of described second wheel 6 parallels with horizontal surface.Described rotational axis line of taking turns joint 7 haply along upper and lower to extension.
Described vehicle frame body 1 is provided with grab rail 4, and described grab rail 4 is positioned at the place ahead of described saddle 3.The top of described grab rail 4 is provided with handlebar.
Do not have diagram, described second wheel 6 has two, and described two second wheels 6 are arranged on described both sides of taking turns joint 7 respectively rotationally.Described second wheel 6 also can have only one, and this second wheel 6 is provided with rotatedly with wheel joint 7.
As shown in Figure 2, have tube chamber 11 on described vehicle frame body 1, the described parts of taking turns in 7 two parts of joint, and being inserted in rotationally in the described tube chamber 11 to small part of another parts.
As shown in Figure 1, the wheel diameter of described second wheel 6 is less than the wheel diameter of described first wheel 2.
Ride when sailing, as gravity center of human body during to right avertence, the described joint 7 of taking turns is that the axle center clockwise rotates motion with described first turning cylinder 9 from top to bottom, thereby second wheel, 6 turning clockwises travel, as gravity center of human body during to left avertence, the described joint 7 of taking turns is that the axle center rotates counterclockwise motion with described first turning cylinder 9 from top to bottom, thereby second wheel 6 turns left and travels.
As shown in Figure 1, described second wheel 6 is located at the preceding bottom of described vehicle frame body 1, and described first wheel 2 is positioned at the rear lower of described vehicle frame body 1.
