Abstract

The invention aims to provide a portable three-wheeled telescopic folding electric vehicle. The vehicle body is designed to have two front steering vehicle wheels and a back driving vehicle wheel. When the electric vehicle is used, two feet of the driver separately step on pedals on the left side and right side of the back driving vehicle wheel, the driver extends two hands to hold a direction handle and drive the electric vehicle in a standing posture; when the electric vehicle turns a corner or the road surface is uneven on the left and right, the direction handle and the two front wheels can move side to side along with the changes of the centre of gravity of the driver; when the traffic is heavy, the vehicle body of the invention can shrink to the half of the overall length to drive slowly; when the vehicle body shrinks and the direction handle is folded in the vehicle body, the electric vehicle can be freely dragged to move; and when the vehicle body and the direction handle are completely folded, the entire electric vehicle has the similar shape and size of a miniature trunk, thus the electric vehicle can be carried with the user. The invention provides a brand new portable and practical means of transport for the travelings of many users.

Description

Three-wheel telescopic folding battery-driven car

Affiliated technical field

The present invention relates to a kind of three-wheeled electric vehicle, especially car body is two preceding steered wheels, a rear drive wheel design, left and right sides stretcher lays respectively at the rear wheel left and right sides, car body can be elastic, the direction handgrip is between two front-wheels, collapsible, flexible, but and the interlock two front vehicle wheels Full Vehicle System that tilts, rotate.

Background technology

Along with improving constantly of people's living standard, also more and more urgent for the energy-saving and environmental protection of the vehicle, light, variety, complementary requirement.At present all huger as main short distance traffic instrument bicycle, the motor bike bodily form, can't realize carrying, with getting with usefulness.

The present invention is as a kind of vehicle, shrinks volume after folding and has only size as the small-sized baggage container, can easily begin a new line or tow, and the individual can carry during trip, with getting with usefulness.

Have data to show both at home and abroad, have Segway Human Transporter and the present invention similar, but their stretcher between front and back wheel, and because be subjected to the restriction of self structure, front and back wheel is all very little, traffic potential is poor, can't use as the main vehicle.

Summary of the invention

The object of the present invention is to provide a kind of portable three-wheel telescopic folding battery-driven car, its car body is two preceding steered wheels, a rear drive wheel design, left and right sides stretcher lays respectively at the rear drive wheel left and right sides, and the direction handgrip is above between two front-wheels, as shown in Figure 1; During use, driver's both feet are stepped on respectively in the rear wheel left and right sides, and both hands protract and hold in the driving of standing of direction handgrip, shown in Fig. 2 A; Turn to when travelling or the road surface about not at ordinary times, direction handgrip and two front-wheels can swing with driver's center of gravity, shown in Fig. 2 B; When crowded traffic, car body of the present invention is retracted to half size before and after can be at any time and slowly travels, shown in Fig. 2 C; When the car body contraction, when the direction handgrip is folded in the car body, this vehicle can arbitrarily tow, shown in Fig. 2 D; When car body, direction handgrip shrink when folding fully, this vehicle appearance has only shape size as the small-sized baggage container, can realize carrying, as shown in Figure 3.The present invention provides a kind of brand new to carry for users' trip, with getting with using the vehicle.

Its mechanical relation is: the connecting pin 49 on the front left wheel assembly 45 is hinged with the connecting bore 50 on the bodywork assembly 53; Connecting pin 48 on the right front wheel assembly 44 is hinged with the connecting bore 52 on the bodywork assembly 53; Connecting pin 47 on the front left wheel assembly 45 is hinged with the connecting bore 40 on the inclination strut bar 41; Connecting pin 46 on the right front wheel assembly 44 is hinged with the connecting bore 43 on the inclination strut bar 41; Connecting pin 55 on the handgrip assembly 54 is hinged with the connecting bore 51 on the bodywork assembly 53; Connecting pin 56 on the handgrip assembly 54 is hinged with the connecting bore 42 on the inclination strut bar 41; Wherein: connecting pin 47 on the front left wheel assembly 45 and the wheelbase between the connecting pin 49, the connecting pin 46 on the right front wheel assembly 44 and the wheelbase between the connecting pin 48, the connecting pin 55 on the handgrip assembly 54 and the wheelbase three equal in length between the connecting pin 56; The two equates vehicle wheel base length between wheelbase between connecting bore 50 on the bodywork assembly 53 and the connecting bore 52, the connecting bore 40 on the inclination strut bar 41 and the connecting bore 43; Connecting bore 50 on the bodywork assembly 53 and the wheelbase between the connecting bore 51, the connecting bore 40 on the inclination strut bar 41 and the two equal in length of wheelbase between the connecting bore 42.Shown in Fig. 7 A.

Principle of work:

Form two transverse supporting rods up and down by bodywork assembly 53, inclination strut bar 41, form three vertical strut bars by handgrip assembly 54, front left wheel assembly 45, right front wheel assembly 44, being hinged is combined into movable parallelogram sturcutre; When handgrip assembly 54 is tilted to the left, drive front left wheel assembly 45 simultaneously, right front wheel assembly 44 is tilted to the left, shown in Fig. 7 B; In like manner, when handgrip assembly 54 is tilted to the right, drive front left wheel assembly 45 simultaneously, right front wheel assembly 44 is tilted to the right.

3. car body telescopic folding mechanism

Car body telescopic folding mechanism exploded drawings is as shown in Figure 8: by front vehicle body assembly 67, aftercarriage assembly 73, go up direction handgrip 60, major parts such as direction handgrip 61 are formed down.

Its mechanical relation is: left side fork core 70, the right side fork core 69 that is fixed on the front vehicle body assembly 67 that be parallel to each other inserts respectively to be parallel to each other and is fixed in aftercarriage assembly 73 left sleeves 72, the right sleeve 71, goes into mutual coaxial front and back slip cooperating relationship; Being parallel to each other is fixed in left slide bar 63, right slide bar 62 on the direction handgrip 60 and inserts respectively to be parallel to each other and be fixed in down in left sliding sleeve 64 on the direction handgrip 61, the right sliding sleeve 65, goes into mutual coaxial slip cooperating relationship; The rotating shaft 66 of following direction handgrip 61 belows is hinged with the pivoted housing 68 in front vehicle body assembly 67 the place aheads, shown in Fig. 9 A.

Principle of work:

When vehicle of the present invention need shrink when folding, aftercarriage assembly 73 front vehicle body assembly 67 forwards slides and draws close, shown in Fig. 9 B, the last direction handgrip 60 of following direction handgrip 61 drives is that bodywork assembly 67 directions are folding forward in the axle center with the rotating shaft 66 of below, shown in Fig. 9 C, last direction handgrip 60 slides fully and is retracted to down in the direction handgrip 61, and this vehicle shrinks folding finishing, shown in Fig. 9 D; When vehicle of the present invention such as needs stretched, reverse operation got final product.
