Description

A kind of vehicle-mounted Wheelchair Accessible
Technical field
The utility model relates to a kind of vehicle-mounted Wheelchair Accessibles, increase a set of stretch to vehicle particular by Machine Design Contracting Wheelchair Accessible belongs to vehicle chassis technology field.
Background technique
As vehicle enters huge numbers of families, vehicle is brought convenience to people's lives.
But existing vehicle structure can not meet the trip requirements of a part of disabled person, either automobile is still now There is certain differences in height for the vehicles such as train, floor and ground, and the people handicapped for disabled person etc., there are also one A little heavier devices etc., get on or off the bus more troublesome.
The multipurpose of automobile also proposes requirement to the structure of current automobile, and traditional automobile mechanism is no longer satisfied one The use demand of partial mass.Currently there is partial automobile to be equipped with the accessible push plate got on or off the bus now, the push plate is independent Be placed in vehicle, be not carried out the inside for being folded in vehicle chassis, taken out when to be needed, main usage mode still according to It stretches and lifts by manpower, be inconvenient, the lesser crowd of strength can not operate, and the device is unable to free extension, occupy The use space of vehicle, causes transport power to waste.
Utility model content
In order to solve existing vehicle chassis can not facilitate meet it is accessible up and down vehicle requirement, the utility model provide A kind of vehicle-mounted Wheelchair Accessible, the channel may be mounted inside vehicle chassis, and when use is stretched out, and make vehicle floor and road Face is connected by gentle slope, is got on or off the bus for wheelchair or other wheeled devices and is provided free pathway, is recovered to after use Inside vehicle chassis, vehicle space is saved.And this mechanism has used electric drive, and it is time saving and energy saving to have the characteristics that.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of vehicle-mounted Wheelchair Accessible mechanism, is mounted between automobile chassis and automotive floor panel;Including two pieces of backplates, power Mechanism, sprocket wheel chain transmission mechanism, guide holder, carrying trolley, upper face, lower face and attachment strap;Wherein:
Two pieces of backplates, power mechanism, guide holders, are separately mounted on automobile chassis, and two pieces of backplates are arranged parallel, And guide holder is located between two pieces of backplates;Sprocket wheel chain transmission mechanism arranges along guide holder, and sprocket wheel chain transmission mechanism The connection of the power output end of power intake and power mechanism, and the power output end of sprocket wheel chain transmission mechanism is then small with carrying Vehicle connection;
It carries and is capable of forming first movement pair between the bottom and guide holder of trolley;
One end of upper face and automotive floor panel between two pieces of backplates are hinged, other end activity setting;
Lower face one end and carrying trolley are hinged, and the other end is then hinged with attachment strap;
Sprocket wheel chain transmission mechanism can drive lower face by carrying trolley under the positive power driving of power mechanism Automobile chassis is skidded off along guide holder, until one end of attachment strap and ground face contact;
Sprocket wheel chain transmission mechanism can drive lower face by carrying trolley under the reverse power driving of power mechanism Automobile chassis is slid into along guide holder, until lower face is slid completely into automobile chassis, the protrusion and automobile bottom at the attachment strap back side at this time Disk is collided, and promotes articulated position rotation of the attachment strap between lower face, until attachment strap is perpendicular to lower face;At this point, upper plate A rectangle frame is surrounded between face, two pieces of backplates, attachment strap and automobile chassis, automotive floor panel, lower face is in rectangle frame, and position In the lower section of upper face.
The second prismatic pair is capable of forming between the upper face and lower face as a further improvement of the utility model, Wherein:
The guide holder, including one piece or more of right angled triangle floor;The right-angle side and automobile of each floor The supporting beam of plate is mutually leaned on, and another right-angle side is fixed on automobile chassis;
The first movement pair, including track and can be along the idler wheel a of tracks travel;Idler wheel a is mounted on carrying The bottom surface of trolley, track are arranged along floor bevel edge;
Second prismatic pair includes the idler wheel b that is oriented to slope and can slide along guiding slope;Slope setting is oriented to exist Lower face, and idler wheel b is installed on upper face;
When idler wheel a is slided along track decline, lower face is driven gradually to skid off the freedom of automobile chassis, drive upper face It slides along the decline on guiding slope by idler wheel b in end;
When idler wheel a is slided along track rising, lower face is driven gradually to slide into the freedom of automobile chassis, drive upper face End is lifted by idler wheel b along the up-slip on guiding slope.
The sprocket wheel chain transmission mechanism includes transmission belt, driving wheel, pressure as a further improvement of the utility model, Bearing up pulley, driven wheel;The side wall of driving wheel, contact roller, driven wheel location and installation in one piece of intermediate floor in each floor, passes Dynamic band is looped around the periphery of driving wheel, contact roller, driven wheel, and is tensioned by contact roller;
Carrying trolley is fixed with transmission belt.
The floor has three pieces as a further improvement of the utility model, and each floor is evenly arranged in two pieces of shields Between plate.
The power mechanism is driving motor as a further improvement of the utility model,;The power of driving motor is defeated Outlet is connect by gear-box with sprocket wheel chain transmission mechanism, and driving motor is set between two pieces of backplates.
The power mechanism further includes hand control box as a further improvement of the utility model,;Gear-box power The power output end of one end of input shaft and driving motor connects, the other end of gear-box power input shaft then with hand control box Power output end connection;Hand control box is mounted on the automobile chassis on the outside of backplate.
