Specific embodiment
With reference to the accompanying drawing and the utility model is described in detail in specific embodiment.
The utility model provides a kind of stair-climbing wheel chair, as shown in Figure 1 to Figure 3, the wheelchair frame 1 including cube, wheelchair
The top of frame 1 is provided with seat 2, and the bottom of seat 2 is provided with obliquity sensor 17, starts supporting mechanism to judge whether,
Wheelchair frame 1 and seat 2 are connected with damper 11, and the upper front end of wheelchair frame 1 is fixedly connected with pedal support 12, pedal support 12
Bottom be provided with foot pedal 13, the top side of wheelchair frame 1 is further fixedly arranged on handrail 14, is provided with controller on handrail 14
15, driving wheel 4, Athey wheel 5, the first electric pushrod 7 or the second electric pushrod 9, the rear end of wheelchair frame 1 are controlled by controller 15
Top is provided with handle holder 16, and pedrail mechanism is provided in wheelchair frame 1, and pedrail mechanism includes two Athey wheels 5 being set side by side,
Two Athey wheels 5 are front and back setting and are driven by driving motor, are fixedly connected with cube between two Athey wheels 5
Connection frame 6, is connected with switching mechanism between pedrail mechanism and the top of wheelchair frame 1, switching mechanism includes being fixed on connection frame 6
On four the first electric pushrods 7, four the first electric pushrods 7 are located at the two sides of 6 rear and front end of connection frame, four first
The other end of electric pushrod 7 is connected to the top of wheelchair frame 1, and supporting mechanism, supporting mechanism packet are also connected on pedrail mechanism
The bracket 8 for being rotatably connected on 6 rear and front end bottom of connection frame is included, inclination is respectively connected between bracket 8 and the bottom of connection frame 6
The second electric pushrod 9, the bottom of bracket 8 is respectively connected with support wheel 10, and the bottom four corners of wheelchair frame 1 are provided with idler wheel, bottom
The idler wheel of portion front end two corners is universal wheel 3, and the idler wheel of 1 bottom rear end two corners of wheelchair frame is driving wheel 4, and driving wheel 4 is logical
It overdrives motor driven.
The universal wheel 3 of the utility model may be implemented to flexibly turn in the movement of level land, convenient movement on level land and
Turning, plays a supporting role simultaneously；Driving wheel 4 is driven by driving motor, is generally had electromagnetic clutch, can be completed hand
Dynamic and electric model mutual conversion, when electromagnetic clutch is in powered version, wheelchair can walk under motor driven, when
When clutch is in manual form, manpower can push walking by guarding frame 16；By the first electric pushrod 7 of control come complete
At the conversion of mode, since the top of pedrail mechanism and wheelchair frame 1 is fixed, when the elongation of the first electric pushrod 7, connection frame is pushed
6 move downward, so that pedrail mechanism decline lands, continue to extend, and wheelchair frame 1 is lifted, and completes wheelchair traveling mode
Conversion.Conversely, the switching that caterpillar drive is moved to level land then may be implemented, switching under the control of the first electric pushrod 7 quickly,
Steadily, stair climbing wheelchair can be allowed to realize free switching in different use environments；Supporting mechanism can be wheelchair in center of gravity
One new supporting point is provided when changing greatly, improves safety of the wheelchair on stair in motion process, stability, comfortable
Property, when electric wheel chair for climbing stairs since stair inclined-plane to when top levels transition, the movement of rear end supporting mechanism, second is electronic
Push rod 9 extends, and pushes the bracket 8 of rear end to decline and contacts to earth, is supported on it on platform, with moving forward for wheelchair, after
The bracket 8 at end gradually lifts under the action of the second electric pushrod 9, and wheelchair is helped smoothly to complete stair inclined-plane to platform
Transient process.When stair climbing wheelchair is gone downstairs, when from top platform to stair chamfered transition, front support mechanism action, second
Electric pushrod 9 extends, and pushes the decline of bracket 8 and the horizontal face contact of second level step of front end, then cooperates with the work of the bracket 8 of rear end
With allowing wheelchair position to be adjusted to the position parallel with stair inclined-plane, with moving forward for wheelchair, center of gravity is slowly transitioned into
On inclined-plane, the bracket 8 of front end is slowly packed up under the action of the second electric pushrod 9, makes wheelchair from level land to stair inclined-plane
Transition is steadily completed.
By the above-mentioned means, a kind of stair-climbing wheel chair of the utility model, by the pedrail mechanism being arranged inside wheelchair frame 1 and cuts
It changes planes structure, wheelchair can be made both can also to carry out stair climbing movement in flat overground locomotion, to solving the elderly and limbs are residual
The trip problem of disease personage is of great significance.
