Abstract

The utility model provides a man-power tricycle which can be driven by hand power or foot power, and can make a driver and passengers seat side by side. The utility model is characterized in that two cranks are installed on a crank shaft at the rear lower end of a middle beam frame, and rear chain wheels are connected with a front chain wheel by chains simultaneously; the two cranks are respectively connected with a connection rod, the front ends of the connection rods are connected with a driving rod and the top ends are sheathed with handlebars. A steering pull rope which is connected with a steering handlebar is fixed to an inner cavity of each handlebar, and the inner sides of the two connection rods are provided with pedals. The right side of a tricycle frame is connected with a side tricycle frame which can be folded or extended through a hinge frame of the side tricycle frame, and a side base which can be folded is arranged between the side tricycle frame and the tricycle frame by the way that the support plate of the side base supports the side base to be connected with the hinge frame.

Description

A kind of manual tricycle

The utility model relates to human-powered vehicle, the especially a kind of manual tricycle that can use the reinforcing simultaneously of hand, pin to drive.

Existing manual tricycle, its type of drive remains traditional and makes circular movement with the pedal stretcher, and sprocket wheel advances by the trailing wheel that chain drives a back sprocket wheel and a side before driving.This type of drive can only be leaned on the strength of shank, and the strength of human arm just can't be utilized.In addition, existing manual tricycle, no matter be loading or holding, its form all be the person for driving a car be not preceding be exactly after vertical arrangement, this to carried no matter be people or goods, all be not easy to look after, when especially manned, both sides exchange just very inconvenient, the existing major defect of this just current available man-power three-wheel vehicle.

The purpose of this utility model is exactly at existing weak point in the prior art, makes hand, the pin powered vehicle of all can exerting oneself and provide a kind of, and is the manual tricycle technical scheme that the parallel arranged of side seat is arranged in the person for driving a car side.

For clearly demonstrating the technical characterstic of this programme, now by a specific embodiment, and in conjunction with its accompanying drawing, the technical characterictic to this programme is described in detail.

Description of drawings is as follows:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the schematic top plan view of Fig. 1.

As can be seen from Figure, the manual tricycle of this programme has a vehicle frame 18, it has middle roof beam structure 4 in the middle part longitudinally, the front end of roof beam structure 4 turns to 2 and front-wheel 1 in this, be fixed with the crank axle sleeve 16 that inner chamber is connected with crank shaft in the posterior end of middle roof beam structure 4, and on the crank shaft of its both sides, respectively adorn a crank 17, sprocket wheel 15 before on a side crank shaft, also being equipped with simultaneously, before sprocket wheel 15 link to each other with back sprocket wheel 11 on being contained in rear axle 12 by chain 14, described rear axle 12 is contained in the rear axle housing 13 that is fixed in vehicle frame 18 rear end lower, and trailing wheel 10 is housed in its left side, on described two cranks 17, respectively connect a connecting rod 20, connect separately tubular drive spindle 6 with hinge respectively at the front end of connecting rod 20, drive spindle 6 again be fixed in swinging mounting 5 on the roof beam structure 4 captive joint, be set with the handgrip 7 that can move at its axis of drive spindle 6 upper edges on the top of drive spindle 6, be fixed with at the inner chamber of handgrip 7 and turn to stay cord 3, this turns to stay cord 3 by drive spindle 6 and pass its sidewall and captive joint with turning to the both sides 2 respectively, at the rear portion of described vehicle frame 18 end face seat shape vehicle seat 8 is housed then, a stretcher 19 is respectively adorned in the inboard of two connecting rods 20 before vehicle seat 8, and handlebar 21 extremely also is housed on the dextral carriage 18 of vehicle seat 8; Connect one on the right side of vehicle frame 18 by sidecar frame hinge mount 22 and can make it the sidecar frame 26 that closes up or stretch out; right side rear wheel 10 is equipped with in the rear end lower outside at sidecar frame 26; and between sidecar frame 26 and vehicle frame 18, connect hinge mount 23 by side seat support plate 25 support-side seats the side seat 24 that can turn up is housed.Minimum angle between described two cranks 17 is 90 degree angles.In addition, a stretcher 19 also is equipped with on the right side on right side connecting rod 20.On the vehicle frame 18 at described vehicle seat 8 rear portions, container 9 is housed also.

Because the preceding sprocket wheel in this programme rotates by crank, connecting rod, stretcher and drive spindle are housed on connecting rod, no matter this be with foot-operated stretcher, still move drive spindle with hand, sprocket rotation before all can driving by connecting rod and crank, therefore, solve all can the exert oneself problem of powered vehicle of hand, pin, also changed the drive form of traditional double-legged circular movement simultaneously.Angle between two cranks is 90 degree, does not have the dead angle before can making during sprocket rotation, promptly when the moment maximum of a connecting rod moment another connecting rod when being zero, so its stable drive is laborsaving.In this programme, a side seat that can close up and can stretch out expansion also is equipped with on the right side of vehicle seat, solved the problem that person for driving a car and rider can not sit side by side, the rider also can be in other power-assisted simultaneously, and when taking, nobody also the side seat can be closed up, reduce occupation of land and account for the road, also very convenient to going out, go into kissing gate.In addition, the turning to of car in this programme is to be realized by moving of handgrip on two drive spindles, so can not influence under the situation that both hands exert oneself, drives by the pulling handgrip and turns to the stay cord pulling to turn to making Vehicular turn.This shows that the utility model has compared with prior art solved the existing in prior technology deficiency, its effect is conspicuous.

Embodiment illustrates in technical scheme, so no longer repeat.
