Swing type tricycle

Abstract

The invention relates to a swing type tricycle. The tricycle body is provided with a tricycle frame, two first wheels movably connected to the front end of the tricycle frame and a second wheel movably connected to the rear end of the tricycle frame, wherein a swing mechanism is arranged between the two first wheels, and when the tricycle body is in an inclined state, the two first wheels are hinged to the tricycle frame; the second connecting rod of the swing mechanism plays a role in supporting and driving the first wheel to deflect, the first connecting rod located above the second connecting rod can restrain the upper portion of the first wheel as well, the first connecting rod and the first wheel are matched to equivalently form a parallelogram structure, deflection is more stable, and angle change is linear; the situation that a large angle is suddenly changed is avoided; besides, due to the design that the first connecting rod and the second connecting rod are restrained on the frame, stress of the two connecting rods can be distributed to the frame to be borne together during deflection, due to the fact that the frame has higher strength, the defect that the strength of the connecting rods is insufficient can be overcome through the design, and the service life of the whole vehicle is prolonged.

Description

technical field [0001] The invention relates to a tricycle, in particular to a swing tricycle whose front two wheels can swing. Background technique [0002] Tricycles, mopeds and recreational vehicles usually have a different model structure from traditional two-wheeled bicycles. Such bicycles are often provided with buckets, compartments, etc. on the front or rear side of the riding position to meet the load-carrying requirements. For example, there is a kind of inverted three-wheel recreational vehicle, the handlebar controls the two wheels on the front side, and the body is also fixed between the two wheels on the front side. Objects or children can be placed in the body, which is convenient for the rider to look after. [0003] For traditional inverted tricycles, during use, the body cannot be tilted, and the two wheels on the front side must fall on the ground together (otherwise it is easy to rollover), and in order to ensure the space of the vehicle body, the distanc...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned tricycle reduces the radius of the tricycle when turning through the inclination of the wheel body, its swing and inclination involves two components, the support frame and the swing control rod, and only the lower support frame and the load-bearing shaft of the car body are produced. In this way, although the tilting of the tricycle is achieved when turning, but due to the lack of connection between the swing control lever and the load-bearing shaft, the restraint of the support frame on the tilting of the vehicle body is insufficient, which is reflected in the abrupt swing of the vehicle body, lack of integrity and It is very uncoordinated; on the other hand, only relying on the support frame as a swing support, when the vehicle body is in a tilted state, the center of gravity completely falls on the support frame, which will make the force distribution of the support frame and its adjacent parts uneven, and long-term use will cause Security risks

Simultaneously, the shock absorber in this patent also can not be adapted on the above-mentioned inverted tricycle

[0006] In addition, the tilt locking mechanism of the tricycle is only set at the joints, which lacks the limit force, and it is easy to cause unnecessary tilt of the body due to accidental touch during daily use
