Abstract

The invention discloses a second-generation foldable tricycle. A tricycle body comprises connected quadrangles; the quadrangles are converted into triangles for fixing the tricycle body in various ways by a method; and favorable conditions are created for developing new tricycle types. The method of folding the tricycle body is changed by locking different rotary directions of hinge pieces. The invention adopts the following scheme: a front face, a main beam, a chassis, a pull rod, a seat beam and a backrest are hinged into two connected quadrangles, and the tricycle body is folded or unfolded through the mobility of the quadrangles. In the quadrangles of the tricycle body, any two hinged pieces are locked in one or two directions, so that the unfolded tricycle body is fixed and can safely run.

Description

Two generation folding tricycle

Affiliated field:

The present invention relates to a kind of three-wheel vehicle, particularly folding tricycle.

Background technology:

At present, though the folding three-wheeled vehicle carriage of an existing generation adopts quadrilateral structure, but only hang a kind of method of girder with the hook of seat beam front end and fix car body, certain limitation is arranged, only be fit to the single short vehicle body vehicle of taking, be unfavorable for that the double long vehicle body vehicle of taking is folding, limited the exploitation of new model.

Summary of the invention:

The present invention seeks to: a kind of folding tricycle is provided, can makes the three-wheel car body of quadrilateral structure be converted into triangular structure in a variety of forms, realize the fixing of car body, make it more can be fit to folding than the long vehicle body.

The technical scheme that the present invention deals with problems is: in tricycle frame, preceding face, girder, chassis, pull bar, seat beam, backrest link into the quadrangle of two disjunctors.Preceding face and girder hinge joint, girder and chassis intersect hinge joint, chassis and pull bar hinge joint, quadrangle before pull bar and the hinge joint of preceding face form, girder and seat beam hinge joint, seat beam and backrest hinge joint, backrest and chassis hinge joint form the back quadrangle, because the quadrangle articulated structure of hinge joint has avidity, so tricycle frame just can freely fold and launch.

Be fit to the human body driving condition when car body launches to reach, car body need be fixed.Any two adjacent parts locking in the quadrilateral structure is become one, quadrilateral structure just is converted into triangular structure, has stability, according to this method, constituting in former and later two quadrangles of three-wheel car body has several groups of adjacent limits that the form of several fixedly car bodies is just arranged, can open up wide space for creating new model according to the optimal one group of adjacent side of the length variable locking of car body.The method that adopts is: as long as any two parts of hinge joint each other in former and later two quadrangles of locking, it is stopped with the cardan axle is that the center of circle relatively rotates, the three-wheel vehicle car body of quadrilateral structure just is converted into triangular structure, and leg-of-mutton stability realizes the fixing of three-wheel car body.

Constitute in the quadrangle of three-wheel car body, along with car body folding exhibition motion, each group two parts of hinge joint each other is that the center of circle is made hour hands and rotated and rotate counterclockwise with the cardan axle.When car body launches to reach suitable human body driving condition, two parts locking on the same cardan axle is become one, its cw and anticlockwise direction are relatively rotated all to be stopped, it is exactly two-way locking, quadrilateral structure car body omnirange after the locking is converted into triangular structure, car body is fixed, in case locking is to fold without the release car body.Set spacing, folk prescription launches to drive relatively rotating of two parts to stoping because of car body, making car body launch motion stops, but do not stop and be prevented from parts and rotate round about, Here it is folk prescription is to locking, and locking back quadrilateral structure car body is in half way around and turns to the triangle state, and car body is subjected to expansion power (seat is stressed) to make the time spent car body to fix, car body is subjected to folding masterpiece time spent car body still to have avidity, and it is namely collapsible to need not release.

With the double folding tricycle of taking this scheme is specified.Double to take the folding tricycle vehicle body longer, should adopt the mode that relatively rotates on locking girder and chassis, and fixedly car body is more reasonable.When car body is done to launch motion, middle part, relative chassis, girder rear portion clockwise rotates, establish platform at the middle part, chassis, girder is pressed on the platform when being fit to human body and driving when car body is deployed into, and platform stops car body to continue to launch to the girder antagonistic force, and platform can only stop girder to clockwise rotate, but can not stop girder to rotate counterclockwise, Here it is monodirectional locking, car body is launched the power effect and is presented stabilized conditions, and folding power effect car body is still collapsible when being subjected to.At the girder rear portion hook is set, aft hook tangles the chassis on the platform when girder is pressed in, and girder cw, conter clockwise all can not be rotated, two-way locking that Here it is, and not opening the hook car body can not fold.For folding needs, driver's seat and the hinge joint of car body middle part, the top that folding back seat seat is positioned at car body is other parts slot milling.For face welding forks arm before the folding needs, forks arm and pedal hinge joint, pedal and connecting rod hinge joint connect and do and the seat beam hinge joint, realize that pedal folds with car body.

Beneficial effect of the present invention: the three-wheel car body with after fixing expansion of a kind of method realization various ways has solved the folding difficult problem of long vehicle body three-wheel vehicle.The methods of adjacent two parts in two kinds of locking quadrilateral structures are provided, bring different influences for the folding operation of car body, the perfect folding of three-wheel vehicle.
