Abstract

An electro-tricycle for the disabled is provided. The electro-tricycle is provided with two front wheels (12); a smaller steering/driving wheel (9) is disposed at the rear part of the vehicle body; steering is realized by steering handles (1) through intermediate connection members which transmit swing to a rear wheel fork (7); the intermediate connection members can be connecting rods, stay cables or hydraulic elements; the rotation axis of the steering handles can be horizontal or vertical; the front wheels are equipped with brake apparatuses (4); and braking is realized through brake cranks (2) on the steering handles. The electro-tricycle for the disabled is suitable for running on the road because the diameter of the front wheels is large, and is also suitable for being used indoors and in the yard because the vehicle body is small.

Description

People with disability's electro-tricycle

Affiliated technical field

This utility model relates to a kind of small-sized electric tricycle, particularly people with disability's electro-tricycle.

Background technology

Existing people with disability's electro-tricycle front portion is a deflecting roller, and trailing wheel is a driving wheel, and its volume is bigger, handles inconvenience, is not suitable for using at indoor and garden; And trailing wheel mostly is monolateral driving, and driving force is unbalanced, can increase cost and weight and adopt two-wheel to drive.

The purpose of this utility model is the deficiency that overcomes existing people with disability's electro-tricycle, provide a kind of handiness, volume less, can use the people with disability's electro-tricycle that suits again at road driving at indoor and garden.

Summary of the invention

This utility model is achieved in that there are two bigger front-wheels this carriage frame front portion, and there is a less driving wheel that turns at the rear portion, and seat is arranged on the vehicle frame, and under-seat has battery; There is the steering tiller that can swing the vehicle frame both sides, and steering tiller is rocked to rear wheel fork by the intermediate connector transmission and turns to realization; Intermediate connector can be connecting rod, can also be drag-line or Hydraulic Elements; The rotation axis of steering tiller can be a level, also can be vertical; Left and right wheels has brake gear, brakes by the brake lever on the steering tiller.

Therefore this utility model is adapted at road driving because two preceding wheel diameters are bigger, again because car body is less, also suits to use at indoor and garden.

The specific embodiment

Below in conjunction with embodiment and accompanying drawing it is described further.

See Fig. 1, Fig. 2, Fig. 3, on this carriage frame 5 seat 15 is arranged, the vehicle frame front end has 12, one less driving wheels 9 that turn to of two front-wheels to be positioned at rear vehicle, turns round with realization by back vent 7 and pivot 10 to turn in vehicle frame central siphon 19; The car body left and right sides have respectively can around with the steering tiller 1 of left and right sides wheel shaft 8 co-axial pivot swingings, brake is arranged 2 and speed control crank 3 on the steering tiller, brake gear 4 can be arranged on the vehicle frame, also can be located on the handle; The steering tiller lower end is fixed with intermediate connector drag-line 13, drag-line 13 rear ends are connected with rear wheel fork 7, swing by left and right sides steering tiller swings trailing wheel and realizes turning to, and left and right sides drag-line can connect at Vehicular body front, turns to thereby one steering tiller also can be controlled; Spring 6 is arranged, so that the handle position relative fixed between handle 1 and vehicle frame; Vehicular body front has foot rest 11, and foot rest 11 can pass through toggle link 16 folding and unfoldings, contacts with ground when foot rest is packed up, and can play the effect of stopping brake.Under-seat can be established damping device 14, and battery 17 can be located at under-seat, and trailing wheel also can be established brake gear, or electronic energy feedback brake, and thing frame or storing basket 18 can be set on it.

See Fig. 4, the pivot 24 of steering tiller is on vehicle frame, and its axis is parallel with left and right sides wheel shaft, and rear wheel fork is connected with vehicle frame by damping device 28, can establish sleeve pipe 21 outside the drag-line 13, so that drag-line can be crooked; Left and right sides front-wheel 12 links to each other with vehicle frame by independent damping device 20.Can establish safety wheel 23 on the foot rest 11, so that vehicle unlikely toppling when leaning forward; Rear vehicle also can be established safety wheel 22, makes the unlikely rollover of vehicle.

See Fig. 5, rear vehicle has seat 29 and pedal 30, and steering tiller both can place seat 15 both sides as shown in Figure 1, also can place seat 15 rear portions, is handled by the occupant on the seat 29.

See Fig. 6, left and right wheels has ratchet 33, and ratchet 31 is arranged on the steering tiller, and drag-line 13 is fixed on the overcoat 32, and overcoat 32 and steering tiller can rotate around wheel shaft 8, and driving control device 34 can make that ratchet engages with ratchet when manual actuation, while handle and overcoat disengaging; When needs fall back or then opposite during electronic travelling, left and right sides handle can be simultaneously by a control device control.

See Fig. 4, there is sprocket wheel 27 steering tiller 1 lower end, drives flywheel 25 driving front-wheels by chain 26 and advances.Also can establish driving control device on handle 1 lower end and the flywheel 25.

See Fig. 7, Fig. 8, Fig. 9, Figure 10, the pivot 24 of steering tiller 1 is vertical with left and right sides wheel shaft, pivot 24 or and drive rod 35 lower ends of pivot one and left and right wheels between ratchet mechanism is arranged, turn to and drive operation like this owing in one plane not being independent of each other.

See Figure 11, Figure 12, Figure 13, Figure 14, two ends, vehicle frame 5 left and right sides are hinged by parallelogram lindage 36 and left and right sides wheel shaft 8, drag-line 37 is connected with connecting rod, motor 39 can drive rolling wheel 38 coiling drag-lines 37 by worm and wormwheel, make the parallelogram lindage alteration of form and make left and right wheels, to adapt to the needs of different occasions the left and right wheels distance apart from change.Can set restriction, motor only just can be opened when automobile low-speed moves, can establish damping device 40 and pulley 41 on the four-bar mechanism 36.

See Figure 15, between vehicle frame rear portion and the steering tube 19 parallelogram lindage 42 is also arranged, thereby also can change after making front tread, drag-line 43 extends to the vehicle frame front portion, is reeled by rolling wheel.

See Figure 16, Figure 17, Figure 19, the drag-line 37 of controlling anterior parallelogram lindage 36 extends to the vehicle frame rear portion by pulley 44, together is directed to the rear wheel fork place with the drag-line 43 of rear portion parallelogram lindage 42, is reeled by reel 52; With co-axial gear 49 of trailing wheel and gear 48 engagements, gear 48 drives reel 52 by worm and wormwheel 50.Gear 49 can engage with trailing wheel by arrangement of clutch, and arrangement of clutch is handled by drag-line 51 or electronic installation.

See Figure 18, parallelogram lindage 36 is by hydraulic cylinder 47 actions, and hydraulic cylinder 47 is connected with motor-driven hydraulic pump 46 by pipe 45.

See Figure 20, hydraulic pump 53 is coaxial with trailing wheel, is connected with trailing wheel by arrangement of clutch, and fluid is by managing 45 to each hydraulic cylinder.
