Description
Technical field
This utility model relates to a kind of can creeping in the vehicle of taking of stair, particularly relates to a kind of electric stairs-climbing wheelchair.
Background technology
Because physical handicap or disease need be taken people with disability and the old people's One's name is legion that wheelchair is gone out.When they lived in the building that does not have electric elevator installation, stair activity had become difficult thing.Five-pointed star of the prior art is wheeled, the track type climbing-building wheelchair can solve the problem of taking advantage of wheelchair-bound people together upward to go downstairs together with wheelchair substantially, but there are some defectives: need the people to try hard to recommend, draw when going downstairs on the wheeled stair-climbing wheel chair of five-pointed star, thereby poor stability, safety coefficient is low; Need the nursing staff to shift wheelchair onto the stairs port place when going downstairs on the track type climbing-building wheelchair, operate again motor, the motion of control crawler belt.Track type climbing-building wheelchair volume is large and heavy, and manufacturing cost is high, and the nursing staff need to be through certain training ability skilled operation.
Summary of the invention
This utility model provides a kind of cost of manufacture not high, simple to operate, the electric stairs-climbing wheelchair of safe ready for the shortcoming that prior art exists.
This utility model electric stairs-climbing wheelchair, its structure comprise chair body, planetary gear set, driving mechanism and seat governor motion four parts.Wherein,
The chair bodily form such as armchair comprise seat, chair lower limb, the chair back and handrail.The occupant towards side meaning before the side, side after occupant's side meaning dorsad;
One group of planetary gear set each side is set below seat, about two planetary gear set connected as one by a power transmission shaft; Planetary gear set is made of wheel disk rack and planetary gear, and wheel disk rack is for supporting plate or the post of planetary gear, and the both ends that the wheel disk rack central part is embedded in power transmission shaft are fixedly connected with, wheel disk rack distal end installing planetary gear; Each planetary gear set comprises 3-5 planetary gear, is evenly arranged at same plane at the wheel disk rack periphery, and size, the thickness of each planetary gear are identical, and each planetary gear equates that with the distance at wheel disk rack center the distance between the adjacent lines star-wheel equates;
Plate shape wheel disk rack is the geometric form of rule, and the corner number that it has is identical with the quantity of planetary gear, and a planetary gear is set up at the position at each angle of plate.That is, wheel disk rack is the equilateral triangle plate when using 3 planetary gears, and wheel disk rack is square plate when using 4 planetary gears, and wheel disk rack is the regular pentagon plate when using 5 planetary gears.The cylindricality wheel disc is put up radial plan, and the quantity of post is identical with the quantity of planetary gear, and the distal end section of each post sets up a planetary gear, and the height of each post is identical, and the angle between the adjacent pillars equates.
Driving mechanism is set below seat.Driving mechanism comprises motor, battery and controller.Motor is connected with transmission shaft driven, and motor is by wire and controller, battery control connection;
Below seat, also be provided with the seat governor motion.The main body of seat governor motion is the rectangular frame structure, and front and back are arranged under seat, and the rear end of rectangular frame is articulated in the rear portion of chair frame, and the middle front part of rectangular frame is hinged by push-pull bar and chair frame.Flexible rectangular frame and the seat of making of push-pull bar done fan-shaped opening and closing campaign, thereby regulates seat together with chair body inclination angle in the horizontal direction.Use this utility model electric stairs-climbing wheelchair to go upstairs or go downstairs, the occupant is the low layer towards stair, and push-pull bar promotes rectangular frame and opens, rectangular frame arrives to stairway step, make seat remain substantially horizontal level, move after making the center of gravity of whole wheelchair, improve stability and safety.
The rectangular frame that consists of the seat governor motion can be H shape framework, and the horizontal connecting rod of 1-3 bar is set between two montants.H shape framework two montant rear ends and chair frame rear portion are hinged, and the lower end of push-pull bar is with laterally connecting rod is hinged.The montant of H shape framework intermittently or continuously contacts stairway step downstairs the time.
As the optimization of seat governor motion, its rectangular frame is made into track structure.About two crawler belts be equivalent to the two perpendicular of H, the horizontal connecting rod of 1-3 bar is set between two crawler belts.Two crawler belt rear ends and chair frame rear portion are hinged, and the lower end of push-pull bar is with laterally connecting rod is hinged.Electric stairs-climbing wheelchair crawler belt downstairs time of installing crawler type seat governor motion rolls at stairway step and advances, and is more stable and smooth and easy than H shape framework.
Push-pull bar in the seat governor motion is Collapsible structure, and the upper end is articulated on the chair frame under the seat, and the lower end is articulated in the middle front part of rectangular frame.The power set of push-pull bar can be motor drive mechanism, pneumatic mechanism, any in surge mechanism or the hand-operated transmission.
As optimization, braking nail hole is set respectively in wheel disk rack and planetary gear corresponding section, will brake nail and insert braking nail Kong Houke and stop planetary gear to rotate, in order to raising in the non-stability of whole electric stairs-climbing wheelchair when climbing the building state.
As optimization, the chair back of chair body is designed to the sectional type structure, the section with section between be connected by fixed connecting piece, can dismantle at upper sections.Screw on and lengthen the backrest sections, the occupant is more comfortable; Screw off the lengthening backrest when climbing the building, the decentralization of adjustable wheel chair prevents the chair trunk bending backwards.
This utility model electric stairs-climbing wheelchair structure is relatively simple, easy to operate, operates steadily, and is safe and reliable.
