Abstract

The utility model provides a two-purpose tricycle for the field of the transportation vehicle, which is characterized in that a front drawing mechanism adopts a single vehicle such as a bicycle or a electric power assistant vehicle or a motorcycle; the front fork part of the single vehicle is fastened with a Y-shaped frame buckled with a reverse Y-shaped frame of a vehicle copper; the shaft extending end of the driving chain wheel of the single vehicle is provided with a clutch and an gap bridge chain wheel driving a chain wheel of the vehicle copper. The two-purpose tricycle can be formed by combining the single vehicle serving as the front drawing mechanism with the vehicle copper; the back wheel of the single vehicle is away from land and does not rotate when the two-purpose tricycle is used; the single vehicle can be conveniently separated from the vehicle copper when the two-purpose tricycle is not used; as a result, the independent driving of the single vehicle is not affected, and the functions of the single vehicle are fully exerted bringing convenience for the living and the production of people.

Description

Dual-purpose tricycle

Technical field

The utility model belongs to the transportation and communication field, relates to three-wheel vehicle, is specifically related to a kind of dual-purpose tricycle.

Background technology

Existing three-wheel vehicle, step on three-wheel vehicle as preceding transporting persons or goods by cart, before draw electro-tricycle, preceding Rameau holder three-wheel vehicle, comprise and draw a mechanism before taking turns, the cart bucket, one draws before taking turns the wheel fork of mechanism is connected with " people " shape frame one on the wagon box wheel shaft, and preceding drawing is connected the chain sprocket drive of the drive sprocket in the mechanism with the wagon box wheel shaft.Draw three-wheel vehicle to bring convenience for people's short-distance transportation a small amount of article before existing, brought into play vital function.But, when not using, precedingly draw a mechanism can not work as bicycle to ride usefulness, cause resources idle not make full use of; And existing bicycle, as bicycle, Moped Scooter, motor bike as running vehicle, can not with the wagon box adapted, cause bicycle can not fully play effect.

The utility model content

The designer in daily life, before use is existing, draw in the practice of three-wheel vehicle and bicycle, find to draw three-wheel vehicle and bicycle to exist above-mentioned defective before existing, through res, the careful observation, update, purpose is to provide a kind of dual-purpose tricycle, and this dual-purpose tricycle can be with bicycle as preceding drawing a mechanism, with existing before draw the three-wheel vehicle wagon box to match to be combined into three-wheel vehicle, can separate does not again influence bicycle and rides usefulness, offers convenience for people's productive life.

Technical solution adopted in the utility model is a kind of dual-purpose tricycle of design, its structure comprises: the cart bucket, before draw a mechanism, wherein before draw mechanism is adopted bicycle (as bicycle or Moped Scooter, motor bike), at the front fork part both sides of bicycle fastening " Y " shape frame, interlock to hang with " people " shape frame on the wagon box wheel shaft and be connected, the trailing wheel of bicycle props up and is placed on " Y " shape frame, at bicycle drive sprocket axle external part power-transfer clutch is set, between power-transfer clutch and wagon box sprocket wheel, the gap bridge driving chain wheel is set.

The utility model is taked technique scheme and measure, to drawing three-wheel vehicle to be improved before existing, designed dual-purpose tricycle, owing on bicycle, set up " Y " shape frame that can interlock and hang with wagon box " people " shape frame, so bicycle is as bicycle or Moped Scooter, motor bike can be as drawing three-wheel vehicle to use before drawing a mechanism and wagon box assembly to be combined into before the three-wheel vehicle; The bicycle trailing wheel can prop up and be placed on " Y " shape frame, and the bicycle trailing wheel is not landed, and reduces resistance; Owing to set up power-transfer clutch and gap bridge driving chain wheel, during use, the bicycle trailing wheel no longer rotates, and does not change wagon box structure and chain wheel location, is more suitable for bicycle and wagon box adapted.When not using, can easily " Y " shape frame that is fastened on the bicycle front fork be disassembled from bicycle together with power-transfer clutch, gap bridge driving chain wheel, and thread off with " people " shape frame of wagon box and to separate, do not influence bicycle and independently ride usefulness, offer convenience for people's life, production, given full play to the effect of bicycle.

Description of drawings

Fig. 1 represents the structural upright scheme drawing of the utility model dual-purpose tricycle.

The specific embodiment

In conjunction with the accompanying drawings and embodiments, further specify the concrete structure of the utility model dual-purpose tricycle, its feature and advantage are clearer.

The embodiment 1 of the utility model dual-purpose tricycle, referring to Fig. 1, its structure comprises: cart bucket 1, bicycle 2 adopts bicycle, as preceding drawing a mechanism, tighten connection " Y " shape frame 3 in the front fork both sides of bicycle, be connected with buckleing to hang by pin between " people " shape frame 7 on wagon box 1 wheel shaft, the trailing wheel of bicycle is raised in " U " shape stull 5 that is carried on " Y " shape frame 3, drive sprocket axle external part at bicycle is provided with power-transfer clutch 4, between the sprocket wheel on power-transfer clutch 4 and the wagon box wheel shaft, gap bridge driving chain wheel 6 is set, 6 of power-transfer clutch 4 and gap bridge driving chain wheels are located on " Y " shape frame 3, the power transmission that bicycle 2 can be produced is moved thereby drive wagon box 1 to wagon box 1 wheel shaft.During use, suitably adjust the height or the angle of bike saddle, make seat ride comfortable handled easily, also the trailing wheel of bicycle can be landed and ride usefulness; When not using, " Y " shape frame 3 is disassembled from bicycle front fork respectively together with power-transfer clutch 4, gap bridge sprocket wheel 6, and thread off with " people " shape frame 7 of wagon box and to separate, do not influence bicycle and ride usefulness separately.

The embodiment 2 of the utility model dual-purpose tricycle, referring to Fig. 1, its structure comprises: in the structure of embodiment 1, bicycle 2 can adopt Moped Scooter as before drawing a mechanism.

The embodiment 3 of the utility model dual-purpose tricycle, referring to Fig. 1, its structure comprises: in the structure of embodiment 1, bicycle 2 can adopt two-wheeled motorcycle as before drawing a mechanism, only needs the two-wheeled motorcycle seat is changed into the sliding seat of adjustment height and angle.

Claims

1, a kind of dual-purpose tricycle, comprise the cart bucket, before draw a mechanism, draw before it is characterized in that mechanism is adopted bicycle, interlock to hang at the front fork part both sides of bicycle fastening " Y " shape frame and " people " shape frame on the wagon box wheel shaft and be connected, the trailing wheel of bicycle props up and is placed on " Y " shape frame, at bicycle drive sprocket axle external part power-transfer clutch is set, and limit bridge driving chain wheel is set between power-transfer clutch and wagon box sprocket wheel.
