Below in conjunction with accompanying drawing and embodiment of the present utility model, the draw gear to the utility model happiness car is described in further detail.
Consult Fig. 1 to Fig. 2, the preferred embodiment of the utility model provides a kind of draw gear of happiness car, its compartment 11 being arranged on happiness car 10 is interior for the wheelchair be positioned at outside compartment 11 20 being pulled traction to compartment 11, or is lowered into outside compartment 11 by the wheelchair 20 being positioned at compartment 11.
Consult Fig. 2 to Fig. 4, in the present embodiment, the draw gear of happiness car of the present utility model includes seat board 100, motor 200, control unit 300, at least one 400, one transmission device 500 of usheing to seat, correspondence are usherd to seat 400 leader tape 600, stop mechanism 700 and a shell 800.
In the present embodiment, seat board 100 is for locking compartment 11 inwall to be fixedly installed in compartment 11 by draw gear.Motor 200 is fixedly installed on seat board 100, and motor 200 is electrically connected control unit 300, and therefore control unit 300 can CD-ROM drive motor 200 operate, and can control turning to and rotating speed of motor 200.
Usher to seat and 400 to be fixedly installed on seat board 100, and usher to seat and 400 there is a tape feed roller 410 that can rotate along its longitudinal axis.
Transmission device 500 power connecting motor 200 and tape feed roller 410, in this enforcement, transmission device 500 comprises the worm gear (not shown) that a worm screw (not shown) of power connecting motor 200 and power connect tape feed roller 410, and worm mesh worm gear and make motor 200 tape feed roller 410 can be driven to rotate through transmission device 500.
Consult Fig. 3 to Fig. 5, one end of leader tape 600 is a winding end 601 and the other end of leader tape 600 is a traction end 602, and winding end 601 is wound in tape feed roller 410.Traction end 602 is provided with a fastener 610 in order to snapping wheelchair 20.In this enforcement, wheelchair 20 is preferably provided with a restraining 30, and restraining 30 has another corresponding fastener 31.
Consult Fig. 4 and Fig. 5, in the present embodiment, usher to seat on 400 and can be provided with at least one pin 421/422, leader tape 600 is wound on the part of tape feed roller 410 between pin 421/422 and tape feed roller 410.Therefore, when tape feed roller 410 furls leader tape 600, pin 421/422 can prevent leader tape 600 from getting rid of de-from tape feed roller 410.Can have multiple different form in the present embodiment central stop lever 421/422, such as a part of pin 421 is for being parallel to the pattern of the straight-bar of tape feed roller 410 configuration; The pin 422 of another part is the pattern of curved bar, and it surrounds tape feed roller 410 at least partially.
Consult Fig. 4, stop mechanism 700 includes ratchet 710, ratchet 720 and an actuator 730, ratchet 710 be hubbed on usher to seat on 400 and also with tape feed roller 410 and axle configure and can rotate by interlock, ratchet 720 is hubbed on corresponding to ratchet 710 and ushers to seat on 400 and can put start by pivot.Ratchet 720 along ratchet 710 single hand of rotation engagement locking ratchet 710 and ratchet 710 cannot be rotated, but ratchet 710 can rotate along its another hand of rotation, and ratchet 710 can be departed from when the start of ratchet 720 pivot pendulum and make ratchet 710 can bidirectional rotation.Actuator 730 is electrically connected control unit 300 and interlock ratchet 720, and therefore control unit 300 can control ratchet 720 pivot pendulum with locking or release ratchet 710.
Consult Fig. 2 to Fig. 4, shell 800 is arranged at seat board 100, and shell 800 shields motor 200, ushers to seat 400, transmission device 500 and stop mechanism 700.Shell 800 offers an opening 801, and opening 801 correspondence is usherd to seat 400 configurations, and the traction end 602 of leader tape 600 passes shell 800 by opening 801.
Consult Fig. 2 to Fig. 4, the draw gear of happiness car of the present utility model more comprises a positioning guide wheel 910, and in the present embodiment, positioning guide wheel 910 preferably corresponding opening 801 is configured at outside shell 800, and leader tape 600 is around on positioning guide wheel 910 after passing shell 800.Positioning guide wheel 910, in order to be located through the part of the leader tape 600 of opening 801, moves in process at traction wheel chair 20 by this, avoids leader tape 600 deflection to rub opening 801 and damaged.
The draw gear of happiness car of the present utility model can configure one in addition depending on the directional selectivity ground of opening 801 and turn to guide wheel 920, guide wheel 920 is turned to be configured at outside shell 800, and opening 801, positioning guide wheel 910 and turn to guide wheel 920 preferably not co-linear configuration, leader tape 600 is around in after walking around positioning guide wheel 910 and turns on guide wheel 920.
Consult Fig. 4 to Fig. 7, in the present embodiment, control unit 300 can be operated through M/C or the mode of wireless remote control, control motor 200 by this to operate, when motor 200 operates, can furl or roll up through transmission device 500 drives tape feed roller 410 to rotate the traction end 602 putting leader tape 600.Wheelchair 20 can be pulled traction in compartment 11 when draw gear retracting leader tape 600 of the present utility model, the wheelchair 20 being positioned at compartment 11 can be lowered into outside compartment 11 when draw gear volume of the present utility model puts leader tape 600.
Moreover in the present embodiment, ratchet 720 preferably puts the hand of rotation monodirectional locking ratchet 710 of leader tape 600 along volume.When ratchet 720 mesh ratchet gear 710, ratchet 710 still can rotate along the hand of rotation of retracting leader tape 600.When ratchet 720 departs from ratchet 710, ratchet 710 can be put the hand of rotation rotation of leader tape 600 along volume or rotate along the hand of rotation of retracting leader tape 600.
When control unit 300 CD-ROM drive motor 200 operates and furls leader tape 600, control unit 300 also controls actuator 730 simultaneously and discharges ratchet 720 and make ratchet 720 mesh ratchet gear 710.Once power failure, motor 200 cannot hold wheelchair 20, but the hand of rotation monodirectional locking ratchet 710 that ratchet 720 puts leader tape 600 along volume can make outside the unlikely landing car of wheelchair 20.
When control unit 300 CD-ROM drive motor 200 operate and roll up put leader tape 600 time, control unit 300 simultaneously also controls actuator 730 start and drives ratchet 720 to depart from ratchet 710, tape feed roller 410 can be rolled up by motor 200 driven rotary and put leader tape 600.Once power failure, motor 200 cannot hold wheelchair 20, but actuator 730 power-off and ratchet 720 is resetted mesh ratchet gear 710, the hand of rotation monodirectional locking ratchet 710 that ratchet 720 puts leader tape 600 along volume can make outside the unlikely landing car of wheelchair 20.
Therefore the wheelchair 20 be positioned at outside compartment 11 can be pulled traction to compartment 11 by motor 200 by draw gear of the present utility model expediently, or is lowered into outside compartment 11 by the wheelchair 20 being positioned at compartment 11.Further, by stop mechanism 700 when power-off monodirectional locking leader tape 600 to prevent wheelchair 20 landing.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
