Chair frame, loading plate mainly are welded by hollow section, and be simple in structure, solid and reliable, light and handy, occupies little space.
Two, this utility model operation principle:
Fig. 2, lower limb plate elevating function principle
The lower limb plate adopts rotating bearing pin to connect with podical plate, and the lower limb plate rotates around rotating bearing pin centrage.The lower limb pan motor also all adopts rotating bearing pin to connect with podical plate and lower limb plate.When patient needs changing position, can directly use the rising or the decline button of the lower limb plate on the hand-held control box, flicking the corresponding button, lower limb plate rise or descend.Release button then stops voluntarily, and the lower limb plate also remains on position when stopping.Press the rising button of lower limb plate, low-voltage direct controller driving leg pan motor, lower limb pan motor push rod stroke is elongated, connect rotation thereby promote the lower limb plate around the rotating bearing pin that connects with podical plate, and beginning is risen slowly.Unclamp the rising button, the lower limb plate quits work.The lower limb plate remains on this position.Press the decline button of lower limb plate, low-voltage direct controller driving leg pan motor, lower limb pan motor push rod stroke shortens, thus pulling lower limb plate connects rotation around the rotating bearing pin that connects with podical plate, and beginning slowly descends.Unclamp the decline button, the lower limb plate quits work.The lower limb plate remains on this position.
Fig. 3, podical plate elevating function principle;
As Fig. 3, crane adopts rotating bearing pin to connect with pony sill, and crane can rotate around this bearing pin centrage, and crane adopts rotating bearing pin to connect with carrier base, and crane can rotate around the bearing pin centrage.When patient needs changing position, can directly use the rising or the decline button of the podical plate on the hand-held control box, flicking the corresponding button, podical plate rise or descend.Release button then stops voluntarily, and remains on the position when stopping.Press the rising button of podical plate, the low-voltage direct controller drives the buttocks pan motor, and buttocks pan motor push rod stroke is elongated, thereby promotes crane around connect rotation with pony sill.Crane is slowly become vertically by inclination, thereby the buttocks plate height that is connected on the mounting is raise.Unclamp the rising button, the buttocks pan motor quits work, and podical plate remains on this position.Press the decline button of podical plate, the low-voltage direct controller drives the buttocks pan motor, and buttocks pan motor push rod stroke shortens, thereby the pulling crane rotates around the axle that connects with pony sill, and beginning is connected in the buttocks plate height decline of propping up on the mounting slowly by vertically becoming inclination thereby make.Unclamp the decline button, the buttocks pan motor quits work, and podical plate remains on this position.
Fig. 4, backboard elevating function principle
As shown in Figure 4, backboard and podical plate adopt rotating bearing pin to connect with a mounting, and backboard and podical plate can rotate around the bearing pin centrage.A podical plate lever and a mounting lever also adopt rotating bearing pin to connect with catch bar, and the three can relatively rotate.When patient needs changing position, can directly use the backboard on the hand-held control box to rise or the decline button, flicking the corresponding button, backboard rise or descend, meanwhile podical plate rotates around the bearing pin centrage that connects with a mounting, and direction is consistent with the backboard direction of rotation.Release button then stops voluntarily, and remains on the position when stopping.Press the rising button of backboard, the low-voltage direct controller drives the backboard motor, and backboard motor stroke is elongated, rotates around the bearing pin that connects with a mounting thereby promote backboard.Backboard is risen.Meanwhile, catch bar promotes a podical plate lever and a mounting lever, thereby podical plate is rotated around the rotating bearing pin that connects with a mounting, and direction is consistent with the backboard direction of rotation.Unclamp the rising button, the backboard motor quits work, and backboard, podical plate remain on this position.Press the decline button of backboard, the low-voltage direct controller drives the backboard motor, and backboard motor stroke shortens, thereby the pulling backboard rotates around the bearing pin that connects with a mounting.Backboard is descended.Meanwhile, catch bar promotes a podical plate lever and a mounting lever, thereby podical plate is rotated around the rotating bearing pin that connects with a mounting, and direction is consistent with the backboard direction of rotation.Unclamp the decline button, the backboard motor quits work, and backboard, podical plate remain on this position.
Be converted into chair shape principle of work and power (as Fig. 2, Fig. 4)
When patient needed changing position, flicking was converted into chair shape button, and the low-voltage direct controller drives the backboard motor, and buttocks pan motor stroke is elongated, rotated around the bearing pin that connects with a mounting thereby promote backboard.Backboard is risen.Meanwhile, catch bar promotes a podical plate lever and a mounting lever, thereby podical plate is rotated around the rotating bearing pin that connects with a mounting, and direction is consistent with the backboard direction of rotation.Meanwhile, low-voltage direct controller driving leg pan motor, lower limb pan motor stroke shortens, thereby pulling lower limb plate rotates around the rotating bearing pin that connects with podical plate, and beginning slowly descends, unclamp and be converted into chair shape button, backboard motor, lower limb pan motor quit work, and backboard, podical plate, backboard also remain on this position.Be converted into chair shape button as pin always, the backboard of electrically propelled chair can rise to extreme position, and the lower limb plate will drop to extreme position and become the seat shape.Release button, backboard, podical plate, backboard also remain on this position.
Shock bit function principle (as Fig. 2, Fig. 4)
When patient need be transformed to the shock position, flicking shock position button, low-voltage direct controller driving leg pan motor, lower limb pan motor stroke is elongated, rotate around the rotating bearing pin that connects with podical plate thereby promote the lower limb plate, and beginning is slowly risen, meanwhile, the low-voltage direct controller drives the backboard motor, and backboard motor stroke shortens, thereby the pulling backboard connects rotation around the bearing pin with a mounting.Backboard is descended.Simultaneously, catch bar promotes a podical plate lever and a mounting lever, thereby podical plate was rotated around rotating movable connection that connects with a mounting, and direction is consistent with the backboard direction of rotation.Unclamp shock position button, backboard motor, lower limb pan motor quit work, and backboard, podical plate, backboard also remain on this position.As pin shock position button always, the backboard of electrically propelled chair can drop to extreme position, and the lower limb plate will rise to extreme position.Release button, backboard, podical plate, backboard also remain on this position.
Three, electric control theory
Electronic control circuit divides three parts, motor of each part control, and the circuit of three parts and components and parts and parameter are identical.Below be illustrated with a part of control circuit wherein: when supposition actuating motor worm screw mediated the optional position, this moment, ascending, descending position limit switch all was in closure state.If press the rising button of hand held controller, motor just changes, and the turbine bar rotates push rod is risen, and when push rod arrived highest order, the raise-position limit switch disconnected, and motor quits work immediately.If by the decline button, the motor counter-rotating, the turbine bar rotates push rod is descended, and when push rod arrives lowest order, falls a limit switch and disconnects, and motor quits work immediately.When push rod mediated the optional position, limit switch all was in opening, and by the rising button, push rod rises; By the decline button, push rod descends.
