Technical Field

The invention relates to the technical field of bicycles, in particular to a fishbone type bicycle.

Background

The bicycle is used as a common vehicle in daily life, and is a common transportation tool for people. However, bicycles on the market generally have the problems of easy toppling during turning, inflexible turning, large turning radius, incapability of turning on narrow roads or in narrow spaces, and the like. In addition, the rear wheel of a common bicycle is a driving wheel, the front wheel of the common bicycle is a driven wheel, and when the rear wheel sinks into or is clamped into a gap, a user must get off the bicycle to lift the rear wheel out, so that the bicycle is very inconvenient.

Disclosure of Invention

The invention aims to at least solve the technical problems in the prior art, and particularly provides a fishbone bicycle which is driven forwards and backwards, is flexible in steering and can quickly avoid obstacles or steer.

In order to achieve the above purpose, the invention provides a fishbone type bicycle, which comprises a main body frame connected with two wheels, wherein the main body frame is made of flexible materials, the left side and the right side of the main body frame are sequentially and vertically provided with reinforcing ribs in a concave manner from front to back, so that the main body frame can generate certain deformation to realize steering when being twisted, a head support rod is vertically arranged on the fish head of the main body frame, handles are arranged on two sides of the top end of the head support rod, when the handles are twisted, the joint of the fish head and the fish body of the main body frame rotates along with the rotation direction of the handles, a saddle support rod is vertically arranged at the back of the main body frame, a saddle is fixed at the top end of the saddle support rod, a driving wheel is arranged in the middle of the main body frame, pedals are arranged on two sides of the driving wheel, and the driving wheel drives the two, a channel for the driving wheel to pass through is formed in the main body frame.

In the scheme, the method comprises the following steps: the grooves on the main body frame are distributed on the front side and the rear side of the driving wheel. Part of the main frame at the driving wheel is not easy to deform, and the driving wheel is ensured to normally rotate.

In the scheme, the method comprises the following steps: the rotation center of the driving wheel is higher than that of the wheel. The synchronous belt can be effectively driven, and the synchronous belt is prevented from being separated.

In the scheme, the method comprises the following steps: the driving wheel is a chain wheel, and the synchronous belt is a chain.

In the scheme, the method comprises the following steps: the main body frame is in an arch shape with the middle part bending upwards. The supporting strength is increased, and the supporting stability is improved.

In the scheme, the method comprises the following steps: the pedal comprises a foot sleeve for the foot to extend into, and the bottom of the pedal is connected with a crank of the driving wheel through a rotating shaft. Is convenient for riding and prevents feet from separating from the pedal.

In the scheme, the method comprises the following steps: the pedal is in a triangular shape with a narrow upper part and a wide lower part. The supporting area of the foot bottom is increased, and the efficiency and the comfort degree of the foot pedal are improved.

In the scheme, the method comprises the following steps: the top end of the seat support rod inclines forwards. The center of gravity is moved forward, and the stability is improved.

In the scheme, the method comprises the following steps: the main body frame is made of nylon or high-density polyethylene. The material is easy to obtain and the cost is reasonable.

In the scheme, the method comprises the following steps: the channel that supplies two hold-in range to pass sets up the main part carriage respectively on the fishbone of left and right sides.

In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that: set up to the fish bone type, turn more nimble, can avoid the barrier fast or turn to, compact structure is light and handy, and the appearance is pleasing to the eye, and required turning radius is less, even also can turn fast on comparatively constrictive road or space. When not in use, the main frame can be bent, and the storage space is saved. Moreover, the gravity center position is easy to change when the folding chair is folded, and the folding chair is not easy to topple. Being equipped with the hold-in range alone, can effectively preventing the influence between two front and back wheels, the front and back is driven together, and it is more convenient to ride.
