Description

The portable multi-purpose electric wheelchair

Affiliated technical field: common manual wheelchair and electric wheelchair.

Background technology: common various common manual wheelchairs, electric wheelchair.The common manual Wheelchair structure is simple, and is easy to use, economical and practical, is widely used.But user is older, muscle power or arm strength is not good then needs the entourage to carry out.It is laborsaving that the electric wheelchair user uses, owing to cost an arm and a leg, heavy inconvenience use such as is carried and limited to.

Summary of the invention: portable multi-purpose electric wheelchair (DYW type) is to adopt the chair body structure of common push-chairs to be reequiped, repacking does not change the former chair body structure of common manual wheelchair substantially, makes the common manual wheelchair increase the major function of electric wheelchair by repacking.

Portable multi-purpose electric wheelchair (DYW type) is to install mounting bracket additional on two heel post main axle positions of common push-chairs (being suitable for the common push-chairs of many moneys), mounting bracket is fixed with a plurality of clips, mounting bracket of installing on a heel post and battery bracket are used for installing driven main wheel and battery, the mounting bracket of installing on the opposite side column is used for installing driving device, driving device is made up of direct current generator and worm reduction gear, directly drive initiatively main wheel of opposite side, direct current generator is joined worm reduction gear, can provide bigger moment of torsion and stable rotating speed, for wheelchair provides driving power.Worm reduction gear is furnished with arrangement of clutch, by clutch handle control, makes things convenient for function conversion, can travel and manpower is changed between carrying out electronic.Between the column of the front and back of wheelchair, respectively install a folding support bar additional, played and strengthened the stable and intensity of wheelchair chair when using, fix two main wheels and two directive wheels between spacing, improved stablizing when wheelchair travels, accurately and safety, the two ends of folding support bar are connected and fixed with the front and back column of clip and wheelchair, there is folding joint the two ends and the centre of folding support bar, the folding intermediary folding joint of support bar has sheath, to guarantee folding support bar stable and reliable when the holding state, it is collapsible to open the folding intermediary sheath of support bar when wheelchair need be packed up.On a side directive wheel (any side is decided by the requirement of user) of wheelchair, install steering tiller additional, Electric Machine Control handle and state switch are housed on the handle, control travelling, advance and retreating of wheelchair.On two front jockey wheels, install folding steering link additional, control two unanimities that directive wheel turns to, steady when wheelchair is travelled, reliable and accurate, the two ends of steering link and middle the same have folding joint and sheath with folding support bar, it is collapsible to open the intermediary sheath of directive wheel folding connecting rod when wheelchair need be packed up.Carrying out also can selecting to install motor control switch on the handle, when carrying out, can select manpower to carry out or electric boosted implementation, to save the manpower of carrying out the people.

Above-mentioned repacking is suitable for the common push-chairs of many moneys, and is simple in structure, applied widely, and its key is the frame for movement design.

Through several partial reequippings of wheelchair, make common push-chairs have the multiple function of push-chairs and electric wheelchair: to take, manually power-assisted is travelled, electronicly travelled, manpower is carried out, folding carry etc.The occupant can advance, retreat or stop by the electronic speed of travelling of the gauge tap on the steering tiller control during use, by the clutch of clutch handle control reductor, selects that manual power-assisted is travelled, manpower is carried out or electronic travelling.Push away the optional gauge tap of carrying out on the handle by control (choosing dress) of selecting of passerby during implementation and use electric boosted implementation or manpower to carry out, several parts of wheelchair repacking have taken into full account occupant's easy to use and safety.The manual electric wheelchair of portable multi-purpose is characterized in: simple in structure, repacking is convenient, widely applicable, be suitable for the common push-chairs of many moneys, the original chair body structure and the function of use that have kept general common push-chairs, increased simultaneously the major function of electric wheelchair again, for the user of wheelchair provides more how easy to use, the labor intensity when having reduced entourage and entourage and carrying out.
