The rotation and lifting vehicle frame
Technical field
The invention belongs to a technical field in the vehicle.
Background technology
The combination of wheelchair and special cycle for disabled people makes the disabled person be sitting in and drives special cycle for disabled people on wheelchair, can farthest enlarge lower limb disability people's autonomic activities scope.In prior art, the technical scheme for this respect of all kinds is arranged.But total some blemish in an otherwise perfect thing of these technical schemes, as some use to bother, operation easier is large, certain structures is complicated, with high costs etc.Can find so a kind of method simple and reasonable, easy to operate, with low cost.This programme is exactly to carry out in this respect the further result of discussion.
Summary of the invention
For the combination of giving wheelchair and special cycle for disabled people is provided convenience, this programme has been taked following technical measures: vehicle frame is divided into fixedly vehicle frame and movable carriage, wheelchair carrying platform is installed on moveable cart, and movable carriage is hinged on fixedly on vehicle frame by hinge, and hinge is not orthogonal to ground; Be stressed that the present invention only limits to provide for the combination of wheelchair and special cycle for disabled people the convenience of a little, rather than for wheelchair be combined with special cycle for disabled people whole.The technical measures of taking only limit to vehicle frame, and the prior art beyond vehicle frame for example drives vehicle frame and opens and closes, wheelchair is fixed on that wheelchair carrying platform is first-class a prior art, is not the problem that the application will solve.So ask the inspector when considering the essential features of the application's claim 1, should be noted that consideration the statement here.
It is simple in structure that the benefit of this programme is mainly located, and its maximum characteristics are hinge out of plumb ground.Because hinge is not orthogonal to ground, the plane of rotation and the ground that are contained in the wheelchair carrying platform on movable carriage are intersected.Also just say, movable carriage is in the process of hinge rotation, and an end that is contained in the wheelchair carrying platform above it not only has the variation of level attitude, and the vertical just variation of degree is arranged, and intersects with ground.These change vertical lift and the horizontal location that just in time is used in wheelchair and special cycle for disabled people cohesive process.It makes wheelchair and special cycle for disabled people cohesive process become simple and convenient, has also simplified complete vehicle structure simultaneously.

The specific embodiment
The present invention is mainly by fixedly vehicle frame 1, hinge 2, movable carriage 3 and wheelchair carrying platform 4 form.Movable carriage 3 and fixedly vehicle frame 1 is hinged by hinge 2.Wheelchair carrying platform 4 is fixedly mounted on movable carriage 3, than axle 2 out of plumb ground, as shown in Figure 1.Due to than axle 2 out of plumb ground, with wheelchair carrying platform 4 during around hinge 2 rotation, its plane of rotation must intersect with ground in movable carriage 3.That is to say due to hinge 2 out of plumb ground, rotate to an angle when opening in movable carriage 3, the rear end that is contained in the wheelchair carrying platform 4 on movable carriage will be intersected with ground, as shown in Figure 2.This state just is being used on the wheelchair carrying platform 4 that falls on wheelchair.When wheelchair is opened upper wheelchair carrying platform 4, when movable carriage 3 was closed under actuating device or Manual-pushing, wheelchair carrying platform also just in time returned to the original place.In this process, the rear end of wheelchair carrying platform has generally produced the lifting that horizontal displacement has also produced vertical dimension.Wheelchair also just in time is positioned on the position of chaufeur in car, the disabled person can be sitting in drive special cycle for disabled people on wheelchair; As long as fixedly between vehicle frame 1 and movable carriage 3, actuating device being installed, just can drive the opening and closing of movable carriage.The operable actuating device of this vehicle frame is a lot, such as using fluid pressure type, screw, steel wire rope type and worm-and-wheel etc.These actuating devices can be manual can be also electronic, actuating device is prior art, is not the problem that the application will solve, also not in the scope of asking for protection.
