Description

A kind of novel plug-type three-wheel vehicle

Technical field

The utility model relates to the vehicle technology field, provides a kind of novel plug-type three-wheel vehicle specifically.

Background technology

At present ride instead of walk the three-wheel vehicle of usefulness of disabled person, the elderly mainly has two kinds of type of drive: a kind of is that hand chain-type drives, a kind of is the plug-type driving of rocking bar, its shortcoming is: the driver train of dual mode all is located at the car body middle part, people's health or two arms will lean forward all the time and hold crank and handlebar when advancing, time has grown the back and arm is ached especially, influence healthy more, and the body part in the middle of also will hiding when getting on or off the bus, very inconvenient concerning inflexible disabled person of legs and feet and the elderly.

Summary of the invention

The purpose of this utility model is intended to improve above-mentioned weak point of the prior art, and a kind of novelty simple in structure is provided, and drives convenient, flexible novel plug-type three-wheel vehicle.

The purpose of this utility model realizes by following proposal: a kind of novel plug-type three-wheel vehicle, it has vehicle frame, handlebar, front-wheel, stretcher, seat cushion, handrail, backrest are installed on vehicle frame, trailing wheel is fixed on the vehicle frame by the trailing wheel axle sleeve, be characterized in, survey face at car body is provided with driver train, driver train comprises handle, the end of handle connects fulcrum shaft, fulcrum shaft is fixed on the vehicle frame, and the other end of fulcrum shaft is connected with rocking bar, and the rocking bar lower end is provided with connecting rod, the other end of connecting rod is provided with crank, and crank is fixed on the hind axle of trailing wheel axle sleeve one end.

The utility model is arranged on the side of car body with driver train, and during use, one holds handlebar grasps direction, the another arm is placed on can be held handle drives and advance on the handrail, health need not lean forward, and not only convenient but also comfortable, the back is difficult for aching, no longer be provided with any parts in the middle of the fwd stretcher, smooth accessible, disabled person, the elderly get on or off the bus extremely convenient, and driver train is reasonable in design, it is convenient and strength-saving to operate, and is a kind of very desirable plug-type three-wheel vehicle.

Below in conjunction with drawings and Examples the utility model is at length explained.

Description of drawings:

Fig. 1-structural representation of the present utility model;

The structural representation of Fig. 2-the utility model drive part;

The structural representation of Fig. 3-the utility model trailing wheel axle sleeve.

The explanation of accompanying drawing drawing:

1 hind axle, 2 cranks, 3 connecting rods, 4 rocking bars, 5 fulcrum shafts, 6 handles, 7 trailing wheels, 8 trailing wheel axle sleeves, 9 bowls, 10 steel balls, 11 grades, 12 vehicle frame pipes.

Embodiment

Referring to Fig. 1, Fig. 2, whole vehicle frame adopts steel pipe manufacturing, handlebar is installed on vehicle frame, front-wheel, stretcher, seat cushion, handrail, backrest, on the hind axle 1 of two trailing wheels 7, trailing wheel axle sleeve 8 is installed respectively, crank 2 is installed on trailing wheel axle sleeve 8 tops on the right side, crank 2 is fixed on the hind axle 1, captive joint one connecting rod 3 on crank 2, the other end fixed installation rocking bar 4 of connecting rod 3, fixed installation one fulcrum shaft 5 on rocking bar 4, fulcrum shaft 5 is fixedly welded on the vehicle frame, end captive joint handle 6 at fulcrum shaft 5, two trailing wheel axle sleeves 8 are welded on respectively on the vehicle frame pipe 12 at vehicle frame rear portion, trailing wheel 7 just is fixedly mounted on the vehicle frame, and the whole erection process is finished.

During use, the people is sitting on the seat cushion, and left hand is held handlebar and grasped direction, and right arm is placed on the handrail, holds handle 6 front and back push-and-pulls, and connecting rod 3 seesaws, and drives hind axle 1 by crank 2 and rotates, and vehicle can be advanced forward backward.Whole Rocker Driving Mechanism operates both convenient, and laborsaving flexibly again, arm can rest on the handrail, is difficult for aching, and because on the middle stretcher any body part is set no longer, does not have obstacle, and it is very convenient to get on or off the bus.

Can not adopt bearing arrangement of the prior art in the trailing wheel axle sleeve 8 of the present utility model, but the fixed installation of the two ends in trailing wheel axle sleeve 8 axle bowl 9, be provided with shelves 11 in the axle bowl 9, shelves 11 fixed covers are on hind axle 1, between shelves 11 and axle bowl 9, be provided with steel ball 10, referring to shown in Figure 3, the axis shelves bowl structure of the similar bicycle of total, its advantage is to rotate flexibly, and cost is more much lower than bearing arrangement.

The utility model can need arbitrarily to install driver train (for example according to disabled person's specific (special) requirements according to the client, driver train can be installed in a left side surveys), driving mechanism structure is simple, easy to maintenance, being arranged on vehicle body side not only operates nimble, and relative to existing technologies, a lot of parts have been saved, cost reduces greatly, and Vehicular body front can be made into movable detachable structure and (adopt grafting as the vehicle frame pipe, be screwed), after handlebar, front-wheel partly unload, can use as common wheelchair.
