Background technology
Wheelchair is the important tool of rehabilitation, and it is not only the walking-replacing tool of limbs the disabled, the more important thing is and makes them by means of wheelchair, carry out physical exercise and participate in social activity.All there is a critical problem in most stair climbing wheelchair in the market, and existing exactly wheelchair Zai Pa can not realize the adjusting of center of gravity while changing pacifically in building, or for mechanism's complexity of center-of-gravity regulating, poor operability.
Summary of the invention
This utility model for current stair climbing wheelchair in level walking functional position stair functional position when conversion up and down, because tilting to make the wheelchair seat, wheelchair tilts, the problem that causes the rider's body unbalance, provide a kind of and can realize the adjusting of seat self-balancing, guarantee that user is at wheelchair during in different conditions, sitting posture remains the seat self-balancing governor motion of balance and stability.
The technical solution of the utility model is: a kind of wheelchair seat self-balancing governor motion comprises the seat 1 that is installed on the wheelchair frame, damping spring 2, gripper shoe 3, heavily puts 4, roller 5, arc track 6, spacer pin 7, axle 8, movable disk 9, positioning disk 10, guide finger 11, support bar 12, strut pin 13, locking latch 14, return spring 15.Between seat 1 and gripper shoe 3, shock-absorbing spring 2 is installed, be welded with balance weight on gripper shoe 3, axle 8 is through balance weight, axle 8 lower ends connect heavily puts 4, heavily put 4 and be arranged on concentric arcs track 6, heavily put that 4 lower ends are provided with roller 5, its side is provided with spacer pin 7, seat 1 chair back is hinged by strut pin 13 and support bar 12, the other end of support bar 12 is equipped with guide finger 11, and guide finger 11 can snap in the cannelure of arc track 6.
The described positioning disk 10 be connected with axle 8, be fixed on movable disk 9, damping spring 2, the locking latch 14 on the wheelchair frame and be enclosed within return spring on locking latch 14 15 and form the axle retaining mechanisms, they can be locked at correct position by seat 1.
Described heavy pendulum 4 is fan-shaped heavy pendulum.
The seat self-balancing governor motion that this utility model provides a kind of stair activity wheelchair to keep its seat level when stair activity, can make the occupant when wheelchair tilts, sitting posture keeps balance and does not tilt with wheelchair, can effectively improve the security and the comfort of user.
Operation principle of the present utility model is: open locking latch 14 when the wheelchair center of gravity changes, the moment of seat 1 front and back end changes, when the moment of rear end is greater than front end, seat 1 front end is upwards steeved, drive the axle 8 on gripper shoe 3, axle 8 is passed to moment of torsion heavily to put 4, heavily put 4 and be subject to the effect of moment of torsion to front slide, effect due to arc track 6, seat 1 is swung by certain radian, while swinging to proper angle, locking seat 1 in the jack of locking latch 14 dependence return spring 15 elastic force insertion respective angles, allow seat 1 keep stable.When wheelchair is got back to horizontal level, open locking latch 14, seat 1 relies on equilibrant to get back to horizontal level, and locking latch 14 relies on return spring 15 elastic force to insert in corresponding horizontal level jack, locking seat 1.
The beneficial effects of the utility model are: no matter wheelchair is walked under what road conditions, allow all the time the seat center of gravity keep balance and reliable and stable, allow user all the time in level, operate wheelchair under state stably.Comfort level and the safety of wheelchair have been improved.
