Abstract

The utility model discloses a wheel chair capable of climbing stairs. The wheel chair capable of climbing the stairs comprises a front planetary wheel set, a back planetary wheel set, a clutch and a seat adjusting mechanism. The back planetary wheel set is a driving wheel set, a hand-operated handrail drives a chain drive mechanism, the chain drive mechanism drives the back planetary wheel set, and the back planetary wheel set transmits motive power to the front planetary wheel set through a chassis. The front planetary wheel set and the back planetary wheel set are connected with the clutch. The seat adjusting mechanism is installed on the bottom of a seat. A handle controls the seat adjusting mechanism. The seat can rotate by a certain angle under the control of the handle and the seat adjusting mechanism. A hand pushing frame is installed on the chassis. The wheel chair capable of climbing the stairs is simple to operate, safe and reliable and overcomes the defects that an existing wheel chair cannot climb the stairs.

Description

Climbing stairs ladder type wheelchair
Technical field
This utility model relates to a kind of climbing stairs ladder type wheelchair, belongs to field of mechanical technique.
Background technology
How the people of a lower limb disability thirsts for the freedom of movement as the ordinary people.Although the appearance of wheelchair, crutch provides a lot of convenience to them.Still can not satisfy their requirement in a lot of occasions.Particularly to live in the people of building more and more along with the raising of people's living standard, and stair activity has brought very big inconvenience for their life.In addition, a lot of lower limb disability people also wish to increase the activity space of oneself.Go to the park to stroll the leisure, but a lot of road surfaces are all rugged and rough in the park, this has brought a lot of troubles to them.Common wheelchair can't be walked at stair, also is very difficult in rugged road surface walking.
The utility model content
This utility model provides a kind of climbing stairs ladder type wheelchair, this wheelchair can stair climbing, also can be in rugged road surface walking as the level land, the adjustable angle joint of its seat, therefore can adapt to the comfortableness of human body according to the angle of actual road surface situation rotary seat, it is simple to operate, by manually realizing, for saving a kind of wheelchair of cost and the energy.
For solving above technical problem, this utility model provides following technical scheme: a kind of climbing stairs ladder type wheelchair, described wheelchair comprises seat, hand handrail, chassis, handle and chain-drive mechanism, two cover planetary gear set, clutch and seat regulators before and after described wheelchair also comprises; Described back planetary gear set is the active drive wheels, and hand handrail takes chain-drive mechanism to, and chain-drive mechanism drives the back planetary gear set, and back planetary gear set is given preceding planetary gear set by the chassis transferring power; Described planetary gear set comprises the vehicle wheel frame of four gears and three wheels and three wheels, and a gear is in the center, and other three gears are in the central gear excircle and mesh with central gear; The gear shaft of central gear also is the center of rotation of vehicle wheel frame, and three wheels evenly are connected on three angles of vehicle wheel frame; Three wheels and three gear opposite face places that are in excircle have the end face tooth; Front and back two planetary gear set connect clutch; Described seat regulator is installed on seat bottom, handle control seat regulator, and seat has the rotation of certain angle under the control of handle and seat regulator; The hand push frame is installed on the described chassis.
Further, described seat regulator comprises that handle, angle modulation frame and seat support, be hinged between described seat support and the seat, the seat support fixation is in the middle part, chassis, the angle modulation frame is articulated in the backrest end of seat, handle is provided with chute, and handle rotates by chute control angle modulation frame along runner movement.
Further, described angle modulation frame comprises and is three poles that hexagonal angle distributes, the hinged seat bottom of pole, and the hinged domain of pole, the chute on the 3rd pole and the handle is for being slidingly connected.
This climbing stairs ladder type wheelchair that this utility model relates to, simple to operate, overcome the defective of prior art, make people with disability's car can be by self strength, imposing external force again can easily make wheelchair climb up stair.
Description of drawings
Fig. 1 is this utility model climbing stairs ladder type Wheelchair structure sketch map;
Fig. 2 is chair angle modulation mechanism structure schematic diagram;
Fig. 3 is clutch and planetary gear set syndeton sketch map;
Fig. 4 is hand handrail driving principle figure;
The specific embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, this wheelchair comprises seat 1, hand handrail 2, chassis 3, preceding planetary gear set, back planetary gear set 4, angle modulation frame 5, handle 7, seat support 8, chute 71, clutch 9, hand push frame 10.Wherein, back planetary gear set 4 comprises planetary gear 41, gear 42, central shaft 43, planetary wheel carrier 44 and central gear 45.
As shown in Figure 4, since the driving force of wheelchair from wheelchair-bound people shake handle by gear drive and chain drive transfer to trailing wheel.When level walking, have only two rear wheel drives.And before the stair activity Clutch Control handle is pulled on.Can as offroad vehicle, be designed to four-wheel drive.Because wheelchair is in the process of stair climbing, roll down from stair easily, perhaps people's strength is difficult to overcome self gravitation and climbs the building, therefore should design hand push frame 10 on the chassis 3 of wheelchair, and people from next door can promote wheelchair, namely climbs up stair smoothly by outer devote every effort to help wheelchair.
As shown in Figure 2, because wheelchair wants stair activity people's health to tilt, can feel very uncomfortable in the above.Designed a kind of seat that can adjust gradient in order to overcome this shortcoming.When stair activity, just can sit comfortably in the top very much as long as regulate a lower handle 7 like this.The structure of the hand-operated brake on the similar automobile of handle 7.At this moment when being in the state of locking, handle 7 want to regulate the gradient of chair as long as a little button will unlock on by lower handle.Up-down adjustment handle 7 just can make seat rotate around the fixing point of support then.So just the gradient of seat can have been regulated.
The brake unit particular importance of wheelchair, otherwise will dangerously take place during stair activity.Owing to drive the front and back wheel upset by handle during the stair activity of wheelchair.Therefore as long as handle does not fall, the runner chair just can oneself not retreat or slide.But the people will have a rest when considering upstairs, can be in the brake unit of a ratchet of rear axle design, and it can make wheelchair be parked in any position of stair.Can adorn the brake gear of a common tricycle when going downstairs at rear axle, the joystick of brake gear is placed on shaking under the handle of wheelchair, handling like this will be very convenient.
The specific embodiment described in the utility model does not constitute the restriction to the application's scope; every within the spirit and principle of this utility model design, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the present utility model.
