Abstract

The utility model relates to a special vehicle for disabled people, which comprises a vehicle frame, a driven walking device and so on, wherein, two power rear wheels are connected with the vehicle frame by a rotating shaft, the rotating shaft is connected with a reducer motor by a chain, two guide front wheels are respectively connected with the front forks which are arranged at the lower ends of the two guide columns, a horizontal pull rod connects the lower ends of the two guide columns, the guide columns are connected with the vehicle frame by column sleeves, and a steering handle which is arranged at the upper end of one guide column is further provided with a hand brake, a brake master cylinder and a Hall handle. The vehicle makes use of the horizontal pull rod to connect the lower ends of the two guide columns together, the guide columns and the vehicle frame have the rotatable bearing connections, so the steering control is simple and easy; at the same time, the power of the vehicle is only driven by one reducer motor, the speed of the vehicle is controlled by the Hall handle, the current direction is changed by using a switch, so as to easily realize the going forward or backward of the vehicle, the structure is simple, the cost is low, the operation is easy, the getting on and off by the disabled people are convenient, the utility model is safe and smooth; in addition, the utility model is provided with the safe brake device, so the utility model is especially applicable to the needs of the disabled people with only one hand.

Description

A kind of special cycle for disabled people

This utility model relates to a kind of special cycle for disabled people.

Existing people with disability's car, for the benefit of control turning to of car, major part all adopts the tricycle form, but the tricycle shortcoming of this form is: its seat front all has some objects to form obstruction, the especially inconvenience of this car falls on the people with disability, the disabled people who relies on double walking sticks to walk of some both legs particularly, it is then essential that others embraces or assists and could realize falling car, and this car can only advance and can not retreat simultaneously; In addition, owing to have only three wheels to land, the carriage that does not just have four-wheel to land can stand stable like that on the ground relatively, when running into obstacle especially in advancing, is easy to overturning, and is for the originally bad people with disability of balance, dangerous especially.The special cycle for disabled people that now also occurs a kind of four-wheel on the market, it is to make power wheel with two trailing wheels, each trailing wheel is respectively by a driven by motor, the stall of each motor, clockwise or reverse and to control by the program of computer controling box, cooperate the running of hand switch again with regard to the may command motor, thereby realize advancing, retreat or turning to of car, as advance, two motors are just clockwise simultaneously or reverse when retreating, when turning to then on one side motor then another motor stop.Car is convenient though fall on this carriage, but its shortcoming is: because complex structure, the shift knob of computer control is more, for the inflexible people of brains, and particularly some apoplexy disabled person or old peoples, accidentally easily push the wrong, even cause the accident, dangerous, the more important thing is this car fare lattice costliness, to most people with disabilitys are sky-high prices, and basic consumption does not rise.

The purpose of this utility model be for overcome above-mentioned shortcoming provide a kind of simple in structure, cost is low, can conveniently control turning to, moving forward and backward of car, on the fall special cycle for disabled people of four-wheel of the convenient and safety and steady of car.

The purpose of this utility model can be achieved as follows: this special cycle for disabled people, mainly by vehicle frame, the driving running gear is formed, it is characterized in that: in the described driving running gear, two power trailing wheel is flexible connection by rotating shaft with both sides, vehicle frame rear portion, sprocket wheel is arranged in the rotating shaft, sprocket wheel is connected with sprocket wheel on the reducing motor through chain, two guide front wheel respectively with the front fork of two lead lower ends for flexibly connecting, two lead lower ends are connected with drag link at the front fork place simultaneously, two leads respectively through column sleeve and with the vehicle frame front part sides for flexibly connecting, wherein the steering handle of the upper end of a lead is provided with that the brake hands that is used to control brake disc in the rotating shaft is pulled and master cylinder and the Hall handgrip that is used to control reducing motor.

This utility model is owing to utilized drag link that the front fork of two leads is connected together, two leads are rotatable flexible connection by bearing and vehicle frame, as long as the steering handle of swing lead upper end just can make two front-wheels rotate arbitrarily toward certain direction simultaneously, what make car turns to control simple.Simultaneously, the power of this car only needs a reducing motor to drive, by the Hall handgrip can stepless control car speed, the sense of current that changes motor by switch can be realized advancing of car or retreat.Contrast the four-wheel car for disabled persons of existing computer control, this car only needs a motor to be used as power, and is simple in structure, the low 3-5 of cost doubly, easy operating contrasts existing tricycle simultaneously, and this car that falls on the people with disability is convenient, safety and steady, this car can easily be realized advancing, retreat and turn to again, is provided with safe brake gear, and the Hall handgrip of this car and brake gear can be installed in either direction last, therefore, even be particularly suitable for having only the individuals with disabilities's of a hands needs.

Below in conjunction with accompanying drawing this utility model is described in further detail:

Fig. 1 is this utility model special cycle for disabled people structural representation.

In Fig. 1, the top of vehicle frame 1 is used to install the seat (not shown), respectively is provided with 14, two power trailing wheels 2 of bearing block in the both sides, rear portion of vehicle frame 1 and is fixed in the rotating shaft, and power trailing wheel 2 is connected for bearing with vehicle frame 1 with bearing block 14 by rotating shaft.The rotating shaft medium position is provided with sprocket wheel, and this sprocket wheel is connected with sprocket wheel on the reducing motor 4 through chain 3.Respectively install and fix a piped column sleeve 9 in vehicle frame 1 front part sides, require and repeatedly repeatedly practise test according to the kinetics of car, column sleeve 9 has about 70 °-80 ° an of angle with horizontal direction, and preferably 75 °, so that the front-wheel of car more helps its walking.Two guide front wheels 5 are installed in respectively on the front fork 7 of two lead 6 lower ends, be that guide front wheel 5 is connected for bearing with front fork 7, front fork 7 places at two leads 6 are connected and fixed together with the lower end of drag link 8 with two leads 6, so that the close look at the swing of two guide front wheels 5.Two leads 6 pass the column sleeve 9 of vehicle frame front end respectively, and the upper and lower side of each column sleeve 9 respectively has a bearing to be used to connect corresponding lead 6, and lead just can be free to rotate with respect to vehicle frame 1 like this, and this similar is in the design that turns to of bicycle.Be equipped with steering handle 10 in the upper end of two leads 6, be used to swing lead.Here, wherein in fact the steering handle 10 of a lead upper end is set as Hall handgrip 13, Hall handgrip 13 is used to control the supplied amount of current of reducing motor 4, just be used to control the gait of march size of car, also be provided with the brake hands simultaneously on this steering handle 10 and pull 11 and master cylinder 12, be connected with the brake disc in the rotating shaft, it is normal establishing that hand that these devices depend on the people with disability on that root lead.Also be provided with the current switching and the reversing switch of control reducing motor 4 in the front portion of vehicle frame 1, also be provided with the pedal that is used to put foot simultaneously.
