Abstract

The utility model provides a rocking-in type wheelchair, which comprises a chair, a driven wheel, two driving wheels and two driving mechanisms which respectively correspond to the two driving wheels,the chair is arranged above a support, the driving wheels and the driven wheel are connected on the bottom of the support in a triangle mode. Two sides of the chair are further respectively connectedwith an armrest frame, and any one of the driving mechanisms is respectively and correspondingly connected on one of the armrest frames and the driving wheels. The wheelchair is operated through an operating rod by hand, and the wheelchair is energy-saving, is convenient to steer, and has convenient and rapid operation and low cost through the mechanical structure.

Description

Shake into formula wheelchair

[technical field]

This utility model relates to a kind of people with disability or patient's walking-replacing tool, particularly a kind of manually operated into formula wheelchair that shakes.

[background technology]

Wheelchair is broadly divided into three kinds of electrodynamic type, intellectual and manual types, and the electrodynamic type wheelchair is higher because of cost, need expend power supply, and relatively heavier, and its speed controlling is difficult to make the user of wheelchair to grasp, and is difficult to promote on market; But intelligent wheel chair Based Intelligent Control, walking automatically, but mainly be in development now, and cost an arm and a leg, be not easy to obtain patient's acceptance; And the manual type wheelchair is because of in light weight, and advantages such as easy to carry and low price make utilization rate higher, but the manual type wheelchair normally directly drives advancing of wheelchair with the wheel figure of hand propelled wheelchair at present, this type of drive is taken strength very much, and turn to inconvenience, speed is slow, and efficiency is lower.Learn that after deliberation it is less that the joystick manipulation wheelchair more directly promotes the handwheel physiological stress.

[utility model content]

The technical problems to be solved in the utility model is to provide a kind of into formula wheelchair that shakes, manual operation, by frame for movement reach laborsaving, be convenient to turn to, simple operation and cost be low.

This utility model is achieved in that a kind of into formula wheelchair that shakes, comprise a seat, a driven pulley, two driving wheels and two corresponding with this two driving wheel respectively driving mechanisms, described seat is located at the top of a support, and described driving wheel and driven pulley are connected the bottom of described support in leg-of-mutton mode; The both sides of described seat also are respectively equipped with an arm-rest frame, and arbitrary described driving mechanism is connected respectively on a described arm-rest frame and the driving wheel accordingly.

Wherein:

Arbitrary described driving mechanism comprises a rocking bar and a connecting rod, the middle part of described rocking bar rotatably is connected on the described arm-rest frame by a rotating shaft, one end of described connecting rod articulates by the rear end of a movable axis and described rocking bar, the other end rotatably is connected on the described driving wheel by second rotating shaft, and there is certain distance at the center that this second rotating shaft departs from described driving wheel.

Arbitrary described driving mechanism also comprises the leader, and this handle is upright to the front end that is connected described rocking bar.

Described driven pulley is connected on the described support by a universal wheel.

The backrest of described seat is to adjust axle by one to be connected with medicated cushion.

Advantage of the present utility model is: by stick manual control wheelchair, the utilization crank and rocker mechanism reaches the driving of wheelchair, the speed difference that utilizes two arms that crank rocker is driven reaches and turns to, can reach laborsaving, simple operation by frame for movement, be convenient to turn to, improve the sport efficiency of user, and cost is low.

Fig. 3 be Fig. 1 along B to structural representation.

Fig. 4 a to Fig. 4 c is the operating state sketch map of driving wheel and driving mechanism thereof.

[specific embodiment]

See also Fig. 1 and shown in Figure 3, the into formula wheelchair that shakes of the present utility model, comprise a seat 1, a driven pulley 2, two driving wheels 3 and two corresponding with this two driving wheel 3 respectively driving mechanisms 4, described seat 1 is located at the top of a support 5, and described driving wheel 3 and driven pulley 2 are connected the bottom of described support 5 in leg-of-mutton mode; The both sides of described seat 1 also are respectively equipped with an arm-rest frame 11, and arbitrary described driving mechanism 4 is connected respectively on a described arm-rest frame 11 and the driving wheel 3 accordingly.

Wherein, described driven pulley 2 is connected on the described support 5 by a universal wheel 22.Described seat 1 also comprises a backrest 13, a medicated cushion 14 and a pedal 15, and described backrest 13 is to adjust axle 12 by one to be connected with medicated cushion 14, can adjust the angle of backrest 13 and medicated cushion 14 by this adjustment axle 12.

Arbitrary described driving mechanism 4 comprises a rocking bar 41, a connecting rod 42 and leader 43, and described handle 43 stands to the front end that is connected described rocking bar 41; The middle part of described rocking bar 41 rotatably is connected on the described arm-rest frame 11 by a rotating shaft 44; One end of described connecting rod 42 articulates by the rear end of a movable axis 45 and described rocking bar 41, and the other end rotatably is connected on the described driving wheel 3 by second rotating shaft 46, and there is certain distance at the center that this second rotating shaft 46 departs from described driving wheel.

Again in conjunction with shown in Fig. 4 a to Fig. 4 c, when the user described handle 43 of holding with a firm grip, and elbow joint is placed on the described rocking bar 41, when wanting wheelchair to advance, only need handle 43 to be mentioned continuously and press down, firmly can make described rocking bar 41 clockwise or counter-clockwise swings in conjunction with elbow joint, further drivening rod 42 promotes or presses down, sail described driving wheel 3 rotations thereby drive, wheelchair can advance.At this moment, the two line 48 of the line 47 at described rocking bar 41, connecting rod 42, second rotating shaft 46 and the center of described driving wheel 3 and the center of described driving wheel 3 and described rotating shaft 44 constitutes a four-bar mechanism, and its action form is forms of motion a kind of anticaustic of existing crank and rocker mechanism.

When turning to, user can utilize two arms that formation one speed difference of controlling of two driving mechanisms 4 is reached the purpose that turns to: during left-hand rotation, only need the operation of the right hand faster than left hand; During right-hand rotation, only need left-handed operation to get final product faster than the right hand.

In sum, the utility model makes up a four-bar mechanism as driving mechanism, anticaustic existing crank The forms of motion of endplay device has been broken through the wheelchair concept of existing conventional design, and disappears in conjunction with the disabled person The person's of expense physilogical characteristics are designed brand-new hommization wheelchair in conjunction with Human Engineering Principle, by machinery That structure reaches is laborsaving, simple operation, be convenient to turn to, improve user's sport efficiency, and cost is low.
