Abstract
The invention provides a folding three-wheel recumbent bicycle. One end of a main girder is foldably connected with a central frame through a main girder folding buckle; two folding arm cradles are arranged in front of the central frame; each folding arm cradle is in axial connection with a folding arm respectively through a rotating shaft, and the folding arms can be folded towards the rear part of the central frame by taking the rotating shaft as an axis; when the folding arms are completely unfolded, the folding arms can be fixed on the folding arm cradles through a fixing device; the far end of each folding arm is provided with a front wheel and a handlebar; three shock-absorption fixing seats are arranged above the central frame, and front shock absorbers on the left side and the right side and a middle rear shock absorber are connected to the shock-absorption fixing seats side by side. According to the folding three-wheel recumbent bicycle disclosed by the invention, the size of each component of the three-wheel recumbent bicycle is reduced, so that the recumbent bicycle is easier to machine and manufacture, and the precision can be well guaranteed. Meanwhile, due to the additional arrangement of the shock absorption mechanisms, the rigid connection of bicycle components is changed into flexible connection, so that the requirement on the rigidity of the bicycle material is reduced and the production cost is lowered.
Description
Technical field
The present patent application relates to a kind of three-wheel recumbent bicycle, especially a kind of folding three-wheel recumbent bicycle, and more specifically one has shock-damping structure, and can carry out the three-wheel recumbent bicycle folding, be convenient to storage.
Background technology
Recumbent bicycle is the new cycle racing form starting in recent years to occur at home, especially three-wheel recumbent bicycle, and three-wheel recumbent bicycle is the three-wheel vehicle operated of can lying down, and this three-wheel vehicle is comfortable, is particularly suitable for the people ridden for a long time.Three-wheel recumbent bicycle, in traveling comfort, stability, safety etc., is obtained for the accreditation of cycling enthusiast, but three-wheel recumbent bicycle volume is comparatively large, and floor area is large, is not easy to pass in and out door, receives also inconvenient at ordinary times.
In addition, the damping performance of three-wheel recumbent bicycle is on the market not good at present, comparatively jolts, has had a strong impact on the traveling comfort of riding, limit applying of three-wheel recumbent bicycle in riding.
Summary of the invention
Namely the present patent application is the above-mentioned shortcoming for three-wheel recumbent bicycle existence on the market at present, provides one to be convenient to fold, and has the three-wheel recumbent bicycle of fine damping effect.
The design of this damping three-wheeled collapsible recumbent bicycle, object will enable three-wheel recumbent bicycle carry very easily, store, park and pass in and out door exactly.It has simplification body construction, makes processing and manufacturing easier; Between body part, use elasticity to connect, reduce the requirement to material stiffness.
Specifically, folding three-wheeled recumbent bicycle described in the present patent application, comprise center am rest, girder, two front-wheels, a trailing wheel, vehicle seat and handlebar, wherein, one end of girder connects center am rest by girder folding fastener, the other end of girder is provided with chain wheel and rides, the top of center am rest is provided with vehicle seat, the rear portion of center am rest connects trailing wheel by rear fork assemblies, the front portion of center am rest is provided with two folding arm reel cages, each folding arm reel cage connects respectively by rotating shaft and a folding arm axle, and folding arm can rotating shaft be that axle center is folding to center am rest rear portion, when folding arm launches completely, can be fixed on folding arm reel cage by anchor fitting, the far-end of folding arm is provided with front-wheel and handlebar.
Further, described anchor fitting is folding arm pin, and folding arm pin, through folding arm, is fixed on folding arm reel cage.It should be understood that described anchor fitting can also comprise other device playing fixation or structures.
Further, the top of described center am rest is provided with three damping permanent seats, left and right sides front shock absorber and middle rear shock absorber are connected on damping permanent seat side by side, and the other end of rear shock absorber is connected on rear fork assemblies, and the other end of front shock absorber is connected on folding arm reel cage.
Further, described front shock absorber and rear shock absorber comprise one or both of spring damper, resistance glue bumper, pneumatic bumper or oil pressure damper.
Further, described vehicle seat comprises cushion and backrest, and described cushion and backrest are integral type or split type.
Further, described cushion and backrest are folding.
The method for folding of the folding three-wheeled recumbent bicycle described in the present patent application: upwards turned over by cushion parallel with backrest, opens girder folding fastener, and girder is upwards folding near backrest, opens anchor fitting, turns round folding arm to parallel with trailing wheel.
Folding three-wheeled recumbent bicycle described in the present patent application, when front-wheel is because of road bump heave and set, the folding arm be connected with wheel is by changing stressed direction with the folding arm reel cage that center am rest is connected, thus damping effect is played in compression or the front damping that stretches; When trailing wheel is because of road bump heave and set, the rear fork assemblies be connected with wheel is by compress or damping effect is played in the rear damping be connected with center am rest that stretches.Because the folding arm reel cage being installed on center am rest both sides is non-interference, form independent suspension, more can adapt to complicated road conditions.Folding arm and folding arm reel cage use folding arm pin to fix, and the angle that folding arm is opened is fixed as design angle, and no matter how to jolt also can not modification for road conditions, improves the stability travelled.
Folding three-wheeled recumbent bicycle described in the present patent application, on the basis not changing the original traveling comfort of three-wheel recumbent bicycle, stability and safety, increases fold mechanism and damping.Car load can distinguish processing and manufacturing, and recombinant together, reduces the size of three-wheel recumbent bicycle all parts, and make processing and manufacturing easier, precision also can better ensure.Simultaneously owing to adding damping, becoming being rigidly connected as flexibly connecting of body part, reducing the rigid requirements to car body materials, reducing productive costs.
