Description
Technical field
The present invention relates to a kind of direction movement shifter for electric wheel-chair vehicle, be particularly well-suited to the electric wheel-chair vehicle of a kind of rear wheel drive.
Background technology
Along with China's aged tendency of population is unexpected with other, there is limbs disturbance in crowd more and more, it is necessary to use wheel-chair as walking-replacing tool. And in wheel-chair, more and more user tend to use electric wheel-chair vehicle. Electric wheel-chair vehicle has laborsaving, comfortable feature, but have to a certain extent and turn to inconvenience, it is difficult to the problems such as translation and shifted laterally, once occur such as dead battery, it is stuck in when being difficult to the situations such as the position outputed, position user and wheelchair being transferred to safety suitable is very difficult, it is difficult to a people realizes. And still do not have a electric wheel-chair vehicle to have the scheme that can rationally solve the problems referred to above both at home and abroad so far.
Summary of the invention
The present invention is to solve that electric wheel-chair vehicle in particular cases shifts the problem of inconvenience at some, and provide a kind of electric wheelchair direction movement shifter, this mechanism can easily realize the electronic conversion moving to direction movement of electric wheel-chair vehicle.
To achieve these goals, the technical scheme is that a kind of electric wheelchair direction movement shifter, including turning axis fixing plate, universal BOGEY WHEEL installed part, universal BOGEY WHEEL, mounting cylinder, strut, pedal, jacking block, rotating shaft, it is characterized in: two pieces turn axis fixing plate and two mounting cylinders are respectively fixedly connected with on the base of electric wheel-chair vehicle, rotating shaft is through turning axis fixing plate, rotating shaft two ends are respectively fixedly connected with pedal, mounting cylinder upper end is provided with jacking block, and jacking block is fixedly connected in rotating shaft, strut is connected by spring in mounting cylinder, strut lower end is connected through mounting cylinder and universal BOGEY WHEEL installed part are fixing, strut upper surface contacts connection with jacking block, universal BOGEY WHEEL installed part universal BOGEY WHEEL installed below.
When stepping on pedal, jacking block rotates pressure strut to fixing point, and is parked in fixing point position, and electric wheelchair back wheels of vehicle levers up unsettled, and keeps four universal wheels of electric wheel-chair vehicle to land.
When being lifted up pedal, jacking block rotates backward, and strut under the action of the spring, moves up, and makes universal BOGEY WHEEL pack up, and electric wheelchair back wheels of vehicle lands.
The invention has the beneficial effects as follows:
Step on the pedal of the present invention, driving axis of rotation thus driving jacking block to rotate, depressing strut, owing to lever principle and body biomechanics need the power stepped on little, until the dead point that jacking block rotates, thus accomplishing that levering up electric wheel-chair vehicle reaches the effect that trailing wheel is unsettled. After trailing wheel is unsettled, the relation owing to having reached jacking block and strut has reached the principle at cam mechanism dead point, and no matter strut still can be parked in current location by many jacking blocks energetically, keeps four universal wheels of electric wheel-chair vehicle to land. As long as now mentioning pedal with foot, will destroying the dead point balance of jacking block, under the gravity of wheel-chair and the effect of mounting cylinder inner spring elastic force, jacking block is original position also, packs up universal BOGEY WHEEL, puts down electric wheelchair back wheels of vehicle.
The present invention can easily realize the electronic conversion moving to direction movement of electric wheel-chair vehicle.

Detailed description of the invention
With embodiment, the present invention is made a step below in conjunction with accompanying drawing to illustrate:
Such as Fig. 1, shown in 4, a kind of electric wheelchair direction movement shifter, including turning the parts such as axis fixing plate 1, universal BOGEY WHEEL installed part 2, universal BOGEY WHEEL 3, mounting cylinder 4, strut 5, pedal 6, jacking block 7, rotating shaft 8, spring 9.
Two pieces turn axis fixing plate 1 and two mounting cylinders 4 are respectively fixedly connected with on the base of electric wheel-chair vehicle, rotating shaft 8 is through turning axis fixing plate 1, rotating shaft 8 two ends are respectively fixedly connected with pedal 6, mounting cylinder 4 upper end is provided with jacking block 7, and jacking block 7 is fixedly connected in rotating shaft 8, connecting strut 5 by spring 9 in mounting cylinder 4, strut 5 lower end is connected through mounting cylinder 4 is fixing with universal BOGEY WHEEL installed part 2, strut 5 upper surface contacts connection with jacking block 7, universal BOGEY WHEEL installed part 2 universal BOGEY WHEEL 3 installed below.
User passes through foot-treadle 6, drive rotating shaft) rotate thus driving jacking block 7 to rotate, pressure strut 5 is until the relation of jacking block 7 and strut 5 arrives its dead point (fixing point), and universal BOGEY WHEEL has beared down on one electric wheel-chair vehicle for 3 times thus accomplishing that levering up electric wheel-chair vehicle reaches the effect that trailing wheel is unsettled. After trailing wheel is unsettled, owing to the relation of jacking block 7 with strut 5 has reached the principle at cam mechanism dead point as shown in Figure 4, jacking block 7 is parked in current location, keeps four universal wheels of electric wheel-chair vehicle to land, as shown in Figure 2.
As long as mentioning pedal 6 with foot, will destroying the dead point balance of jacking block 7, under the gravity of wheel-chair and the effect of mounting cylinder 4 inner spring elastic force, jacking block 7 goes back original position, packs up universal BOGEY WHEEL 3, puts down electric wheelchair back wheels of vehicle. Electric wheel-chair vehicle replys originally electronic state as shown in Figure 3.
