Abstract

Provided is an electrically propelled wheelchair capable of going upstairs and downstairs. The inventor considers the particularity of users, safety and practicality are emphasized since the beginning of design, importance is paid to the function of regulating the upper limbs, and large wheels are controlled through hand-operated brake handles to go upstairs and downstairs, so that not only is arm power enhanced, but also safety is guaranteed. Although the wheelchair is provided with nine wheels, when the wheelchair operates, only three wheels make contact with the ground to support a seat with the very low center of gravity; whether the wheelchair operates on the flat ground or goes upstairs and downstairs, the safety accidents that the wheelchair falls forwards, backwards and sideways cannot occur, and namely the wheelchair is safe. Only if a user has healthy arms, the user can go upstairs and downstairs easily by operating the wheelchair according to regulations. In addition, pedal plates are also safety plates and guard plates, it does not matter that the feet of the user are not good, even if the user feels tired when going upstairs on the half way, the user has no fear and can have a rest on the spot, the pedal plates will automatically play a protecting role to enable the wheelchair to be stopped between stairs, and the key point of the electrically propelled wheelchair capable of going upstairs and downstairs lies in this.

Description

Can go up electric wheelchair downstairs

Technical field

Disabled people group's walking-replacing tool " electric wheelchair " its feature be volume little, can go up downstairs, safe and practical, the room of can arbitrarily coming in and going out.As long as upper limb is healthy, just can use safely.It is disabled people scholar's desirable walking-replacing tool.

Background technology

Disabled people person is the most worried, has lower limb not go, and life is limited to, and does not go out room, be unable to do without bed, just like the frog in well.Though have now wheelchair miscellaneous, can't resolve severely disabled people person's problem of riding instead of walk.Social development now, scientific and technological progress, also this is through with the life of severely disabled people person well frog, can go up electric wheelchair downstairs and can help them, improves their quality of life, and directly wheelchair is gone downstairs, is had a walk from the bed, outing do not worry.

Summary of the invention

Electric wheelchair can be gone up downstairs, and primary problem is safety.This is the problem that inventor solves emphatically, so this wheelchair is peculiarly shaped, and structure is special.By 8 steamboats, form two bull wheels.Bull wheel inclined shaft, two-wheeled becomes eight shapes, additional motor traction wheel, three-wheel becomes A-frame, is holding in the palm the very low seat of center of gravity, so just can effectively prevent slip, layback and rollover.Level land operation steamboat, upper downstairs with bull wheel, sitting case both sides has lift stand, first that the steamboat picking-up of two, front is unsettled before operation, allows its three-wheel land, and reduces ground drag, turns to flexibly.

Respectively there is the brake lever of controlling bull wheel wheelchair both sides, and brake lever respectively has two locks up and down, tooth lock and hole lock.With tooth lock, the handle that operates a switch backward, often pulls position of 90 ° four little rotations upstairs, and upper level step is just pulled continuously above continuously, if rest, pedal blocks at once, prevents that wheelchair from not rolling down.Pedal as required height is adjustable, and downstairs, with hole lock, the handle that operates a switch forward, goes downstairs step by step.Attention: preferably someone assists!

Below in conjunction with accompanying drawing, be described further

Accompanying drawing 1 is clambing wheel chair side view up and down, and sided configuration is identical

Accompanying drawing 2 can upper and lower clambing wheel chair rearview, the three-wheel shape that lands while mainly showing two bull wheel eight shapes and operation

Accompanying drawing 3 is clambing wheel chair internal anatomy up and down, lays down a side bull wheel, each parts usage and function of going downstairs on displaying wheelchair

The specific embodiment

The upper and lower clambing wheel chair of energy, level land is steamboat 2 for operation, upper going downstairs with bull wheel 4, before operation, first front steamboat is lifted with brake lever 3, hold (accompanying drawing 3 has mark) make it unsettled liftoff with lift stand 8, rear two-wheeled operation is drawn in motor wheel 1 holder, can reduce ground drag like this, turn to flexibly.Turn direction upstairs, after forward, backward after the previous dynasty, brake lever pins tooth lock 5 and pulls backward, bull wheel turns 90 ° of steamboat upper level steps, pedal is also caught up with one-level step protection wheelchair and is not rolled down, pulls continuously, just upper continuously, pedal is also followed continuously.Downstairs brake lever lockhole lock 6 is pulled forward, goes downstairs step by step.Note: downstairs must someone nurse.

Claims

1. wheelchair bilateral bull wheel is respectively comprised of four steamboats, and cross structure is controlled and rotated by brake lever, has upper function downstairs.
