Description
Technical Field
The invention relates to a tricycle, in particular to a swing type tricycle with front two wheels capable of swinging.
Background
Tricycles, mopeds and recreational vehicles generally have a different model structure than conventional bicycles with two wheels, and such bicycles are often provided with a hopper, a compartment and the like at the front side or the rear side of the riding position to meet the load bearing requirement. For example, there is a tricycle with two wheels, the front wheels are controlled by the handle bar, the hopper is fixed between the two wheels, and the hopper can be used for placing articles or for children to sit on, so that the rider can look after the hopper.
For a traditional inverted tricycle, in the use process, a bicycle body cannot be inclined, two wheels on the front side must be lifted to fall on the ground (otherwise, the bicycle is easy to turn over), and in order to ensure the space of a bicycle hopper, the distance between the two wheels on the front side cannot be too small. Especially, when the bicycle is turned greatly (for example, the bicycle is turned by 90 degrees or more to the left/right), the centrifugal effect caused by turning can not be compensated by the inclination of the bicycle body like the traditional bicycle, so that the turning radius of the bicycle is generally larger, and when a heavy object is loaded on the hopper, the turning radius is even larger, and the accident of side turning is easy to happen due to carelessness and is not safe enough. In order to ensure safety, when a rider needs to make a large turn, the rider often pushes the rider to get off the bicycle, so that the existing recreational vehicle is inconvenient to use in practice.
For this chinese patent with patent number CN200720011505.3 (publication number CN201023610Y) just discloses a novel tricycle, this tricycle includes automobile body, wheel bumper shock absorber, rotatable coupling is made with swing control lever both ends on the bumper shock absorber upper portion of back wheel, swing control lever middle part is equipped with the control shaft, rotatable coupling is made with the support frame both ends in the middle part of the bumper shock absorber of back wheel, the middle part of support frame be equipped with the automobile body to the horizontally bearing axle before to, rotatable coupling is done with the support frame to the bearing axle, rotatable coupling is done with the automobile body to the control shaft, the bearing axle is fixed on the automobile body. It should be noted that the shock absorber in this patent is applied to a common tricycle with two wheels on the rear side, not to the inverted tricycle described above. The two rear wheel shock absorbers, the support frame and the swing control rod form a four-bar linkage mechanism, so that the two rear wheels of the tricycle always contact the ground when the tricycle turns, and the purpose of preventing side turning is achieved.
Although the tricycle reduces the radius of the tricycle during turning through the wheel body tilting mode, the swinging tilting of the tricycle relates to two parts, namely the support frame and the swinging control rod, and only the support frame below is associated with the bearing shaft of the tricycle body, so that the tilting of the tricycle during turning is realized, but the lack of the association between the swinging control rod and the bearing shaft leads to insufficient restriction of the support frame on the inclination of the tricycle body, and the tricycle is reflected in that the tricycle body swings suddenly and lacks integrity and is quite uncoordinated; on the other hand only leans on the support frame as wobbling support, when the automobile body is in the tilt state, the focus falls on the support frame completely, can make support frame and adjacent partial atress distribute unevenly, and long-term use can cause the potential safety hazard. Also, the shock absorber of this patent is not adaptable to the inverted tricycle described above.
In addition, the tilt locking mechanism of the tricycle is only arranged at the joint, the limit force is lacked, and the tricycle is easy to tilt unnecessarily due to mistaken touch in daily use.

Generally, a handlebar 112 is provided on the frame 11, and the steering of the vehicle body 1 is realized by the steering mechanism 7. Specifically, the steering mechanism 7 in the present embodiment includes a steering seat 71 and two steering rods 72, a power input end of the steering seat 71 is connected to an output end of the handlebar 112 and can rotate synchronously with the handlebar 112, one end of each steering rod 72 is connected to a corresponding side of the steering seat 71, the other end of each steering rod 72 is connected to a rear side of a corresponding first wheel 13, and under the rotation action of the steering seat 71, the steering rod 72 drives the first wheel 13 to deflect towards the rotation side, and the deflection axis of the first wheel 13 extends vertically. The steering mechanism is a conventional configuration of a tricycle and will not be described herein.
During steering, the yaw and tilt of the vehicle body 1 is realized by a swing mechanism R, which is arranged between two first wheels 13 and specifically comprises a first connecting rod 2 and a second connecting rod 3, wherein the middle part of the first connecting rod 2 is rotatably constrained on the vehicle frame 11, the rotation axis of the first connecting rod 2 is consistent with the extending direction of the vehicle frame 11, and two ends of the first connecting rod are respectively connected with the first wheels 13 in a manner of being capable of deflecting towards the left side or the right side relative to the first wheels 13; the second connecting rod 3 is arranged below the frame 11, the middle part of the second connecting rod 3 can be rotationally constrained on the frame 11, the rotating axis of the second connecting rod 3 and the rotating axis of the first connecting rod 2 are arranged in parallel up and down and can move in a staggered mode left and right, two ends of the second connecting rod 3 can be respectively connected with the first wheels 13 in a manner of deflecting towards the left side or the right side relative to the first wheels 13, and two ends of the second connecting rod 3 are always located below two ends of the first connecting rod 2.
