Abstract
The invention relates to an operating arm, in particular to an electric wheelchair operating arm. Forward-backward movement control and steering control of the novel operating rod are separated, so that operating stability is improved, operating difficulty is lowered, and more convenience is brought to weak old people and the disabled to use. An elongated hole is formed at one end of a handle, the lower end of a manual operating rod penetrates the elongated hole and is connected with a shaft end cap fixed at the bottom of the handle through a shaft, a position, close to the bottom end face of the handle, of the manual operating rod is fixed at the bottom of the handle through a first centering spring, the first centering spring is arranged along the length direction of the elongated hole, the other end of the handle is movably connected with a handle centering mechanism, the top end face of a handle shaft is fixedly connected with the bottom end face of the handle, a sleeve and a nylon plug are sequentially sleeved on the outer side of the handle shaft, the handle shaft is connected with a cylindrical pin, two ends of the cylindrical pin are connected with a shell through a second centering spring, and the shell is sleeved on a wheelchair frame. The electric wheelchair operating arm is used on an electric wheelchair.
Description
Technical field
What the present invention relates to is a kind of action bars, and what be specifically related to is a kind of electric wheelchair action bars.
Background technology
Wheelchair is the important tool of rehabilitation, that user is able to a kind of important tool that life activity is taken care of oneself, it is not only the walking-replacing tool of limbs the disabled, the more important thing is and make them by means of wheelchair, carry out physical exercise and participate in social activity, so the use amount of electric wheelchair is very large.Action bars is the indispensable device that wheel chair sport is controlled, traditional action bars adopts joystick structure, seesaws to control to concentrate on a short and small action bars with turning to control, and manual dexterity, operant skill is had relatively high expectations, be not easy to the weak elderly and the disabled and use.
Summary of the invention
For the deficiency existing in prior art, the present invention proposes by seesawing, to control the Novel operating separated with turning to control, has improved the stationarity operating, has reduced operation easier, and the weak elderly and the disabled that is more convenient for uses.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of electric wheelchair action bars mainly consists of handle centering body, handle and hands behaviour bar, and one end of handle has strip hole, and the lower end of hands behaviour bar is connected by axle through strip hole and with the hubcap that is fixed on handle bottom, hands behaviour bar is fixed on the bottom of handle near the position of handle bottom face by the first centralizing spring, on the length direction of the first centralizing spring prolongation cylindrical void, arrange, the other end of handle is flexibly connected with handle centering body, handle centering body is mainly by the second centralizing spring, nylon plug, sleeve, straight pin, Handle axis and shell form, Handle axis top end face is fixedly connected with handle bottom face, there are sleeve and nylon plug in Handle axis outside successively cover, Handle axis is connected with straight pin, the two ends of straight pin are connected by the second centralizing spring with shell, casing is on wheelchair frame.
Forward-reverse motion sensor is housed in hubcap.Divertical motion sensor is installed in the bottom of handle centering body.Seesawing to control with turning to control is separated, and both are separate, and operational stability is good.
The first centralizing spring adopting and the second centralizing spring are two Compress Springs, and its centering is good, compact conformation.
Handle of the present invention and hands behaviour bar have respectively automatic centering mechanism, automatic centering while making handle and hands behaviour bar not be subject to external force.When the present invention realizes direction and speed controlling flexibly by electric wheelchair action bars, seesaw and control and turn to control separated, more meet people's operating habit, smooth operation is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric wheelchair action bars of the present invention; Fig. 2 is electric wheelchair action bars hands behaviour bar automatic centering mechanism structural representation of the present invention; Fig. 3 is the radial section schematic diagram of electric wheelchair action bars handle centering body of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail
Referring to Fig. 1,2 and 3, a kind of electric wheelchair action bars mainly consists of handle centering body 2, handle 3 and hands behaviour bar 5, and one end of handle 3 has strip hole, and the lower end of hands behaviour bar 5 is passed strip hole and is connected by axle with the hubcap 4 that is fixed on handle 3 bottoms, hands behaviour bar 5 is fixed on the bottom of handle 3 near the position of handle 3 bottom faces by the first centralizing spring 6, on the length direction of the first centralizing spring 6 prolongation cylindrical voids, arrange, the other end of handle 3 is flexibly connected with handle centering body 2, handle centering body 2 is mainly by centralizing spring 7, nylon plug 8, sleeve 9, straight pin 10, Handle axis 11 and shell 12 form, Handle axis 11 top end faces are fixedly connected with handle 3 bottom faces, Handle axis 11 outsides are overlapped successively sleeve 9 and nylon plug, Handle axis 11 is connected with straight pin 10, the two ends of straight pin 10 are connected by the second centralizing spring 7 with shell 12, shell 12 is enclosed within on wheelchair frame 1.
Wherein, described the first centralizing spring 6 is two Compress Springs.Described the second centralizing spring 7 is two Compress Springs.
On a upper scheme basis, forward-reverse motion sensor is housed in hubcap 4.
On such scheme basis, divertical motion sensor is installed in the bottom of handle automatic centering mechanism 2.
Shown in Fig. 2, hands behaviour bar 5 is realized automatic centering by the first centralizing spring 6, guarantees that hands behaviour bar 5 automatically restores to initial position when not being subject to external force.
Shown in Fig. 3, handle automatic centering mechanism 2 is comprised of the second centralizing spring 7, handle nylon plug 8, handle jacket 9, straight pin 10, Handle axis 11, cabinet 12.Handle 3 is not only realized the axial location of its Handle axis 11 by straight pin 10 and the second centralizing spring 7, also can automatic centering.
Before electric wheelchair starts and while stopping, handle 3 and hands behaviour's bar 5 centering under the effect of automatic centering mechanism, the control of grasping bar 5 and handle 3 by opponent during electric wheelchair operation can realize to be advanced, retreat, turns to, accelerates and slows down.It is simple in structure, easy to operate, and security performance is high.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the knowledge of describing in above-described embodiment and description illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention has appending claims and equivalent thereof to define.
