Abstract
The invention discloses a single-hand operation disabled tricycle which comprises a frame, brake pads, a driving mechanism and two driven rear wheels, wherein the frame comprises a front fork connected with a wheel, a rear fork and a seat; the front fork is rotatablely connected with the frame; the single-hand operation disabled tricycle is characterized in that the driving mechanism is a crank-link mechanism formed by the front fork, a steering lever, a rocker, a crank disc and a connecting rod, wherein the steering lever is fixedly connected with the front fork; the upper end of the rocker is provided with a handle, and the lower end of the rocker is articulated with a vertical surface of the steering lever; the crank disc is connected with the front wheel in a coaxial way; the two ends of the connecting rod are respectively articulated with the peripheral part of the crank disc and the middle part of the rocker; the diameter of the front wheel is larger than those of the rear wheels; and the brake pads are respectively arranged at the two sides of the front fork and the rear fork. The single-hand operation disabled tricycle overcomes the defect that the traditional disabled tricycle can not be driven, steered and braked by a single hand.
Description
Technical field
The invention belongs to the technical field of vehicle for disabled person.
Background technology
At present, China's disabled person's quantity has surpassed 8,000 ten thousand, much all is only hand or people with one-handed activities ability among these people, although manpower car type class for disabled persons is a lot of at present, but all be to realize operation by both hands greatly, just can not use these cars for above-mentioned disabled person.
Summary of the invention
The invention discloses a kind of one-handed performance disabled person three-wheel vehicle, this invention can one-handed performance, realizes driving, brake and turning function, has remedied the deficiency of traditional disabled person's three-wheel vehicle.
For solving the problems of the technologies described above, the invention provides following technical scheme: a kind of one-handed performance disabled person three-wheel vehicle, comprise vehicle frame, brake facing, driver train and two driven trailing wheels, wherein, vehicle frame comprises the front fork that is connected with wheel, back vent and seat, front fork and vehicle frame are rotationally connected, described driver train is by front fork, deflecting bar, rocking bar, the piston crank mechanism that crank disc and connecting rod consist of, wherein, deflecting bar is captiveed joint with front fork, it is hinged that the upper end of rocking bar is provided with handle and lower end and deflecting bar vertical surface, crank disc is connected with front-wheel is coaxial, the two ends of connecting rod are hinged with the middle part of crank disc perimembranous and rocking bar respectively, and front wheel diameter is greater than rear wheel diameter, front fork, brake facing is equipped with respectively in the back vent both sides.
Compared with prior art, the invention has the advantages that: adopt three wheel mechanisms, a front-wheel, two trailing wheels, and the radius of front-wheel is greater than the radius of trailing wheel, so that improve the speed of a motor vehicle; Front-wheel adopts piston crank mechanism to drive, and the forward-reverse by rocking bar control car and turning to makes things convenient for the people of one-handed activities ability to use; Compare traditional car for disabled persons, brake facing is equipped with respectively in this disabled person tricycle front fork, back vent both sides, and making in case of necessity, the speed of car can in time reduce.
Further, rocking bar is connected with rod slide by movable sleeve, and movable sleeve is locked on the operating handle by eccentric wheel, if car just runs into two dead center positions of quadric linkage when starting, can mobile movable sleeve, change the position on operating handle, break away from the constraint of dead center position.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of one-handed performance disabled person three-wheel vehicle;
Fig. 2 is the upward view of a kind of embodiment of one-handed performance disabled person three-wheel vehicle.
The specific embodiment
As depicted in figs. 1 and 2, a kind of one-handed performance disabled person of this mechanism three-wheel vehicle, comprise vehicle frame 1, rear wheel brake sheet 2, driver train and two driven trailing wheels 3, wherein, vehicle frame 1 comprises the front fork 4 that is connected with wheel, back vent 5 and seat 6, front fork 4 is rotationally connected with vehicle frame 1, driver train is by front fork 4, deflecting bar 7, rocking bar 8, crank disc 9, the piston crank mechanism that connecting rod 10 consists of, deflecting bar 7 is captiveed joint with front fork 4, it is hinged at vertical guide that the upper end of rocking bar 8 is provided with handle and lower end and deflecting bar 7, crank disc 9 is connected with front-wheel is coaxial, and the two ends of connecting rod 10 are hinged with the middle part of crank disc 9 perimembranous and rocking bar 8 respectively, and front wheel diameter is greater than rear wheel diameter.The rocking bar 8 that rocks back and forth, rocking bar 8 drivening rods 10 rotate crank disc 9, and crank disc 9 drives that front-wheels 10 advance or goes afterwards; Axle head is inserted in the vehicle frame 1 fork cover foremost on the front fork 4, rocking bar 8 rocks from side to side, thereby drive deflecting bar 7 and order about wheel steering, brake facing 11 is installed in front fork 4 both sides, brake facing 11 is equipped with respectively in two back vent both sides, when needs slow down, the brake on the pulling rocking bar 8,11 pairs of car brakeings of brake facing.Rocking bar 8 is by movable sleeve and connecting rod 10 sliding block joints, movable sleeve is locked on the rocking bar 8 by eccentric wheel, if car just runs into two dead center positions of quadric linkage when starting, and can mobile movable sleeve, the constraint of dead center position is broken away from the position of change on rocking bar 8.
For a person skilled in the art, under the prerequisite that does not break away from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
