Description

Electronic die set for the wheelchair use

Technical field

This utility model relates to a kind of electronic die set, particularly a kind of electronic die set for the wheelchair use.

Background technology

For general handicapped person, for making its shift position smoothly, wheelchair is a utensil quite easily.With the design of wheelchair now, probably can divide into manual wheelchair and electric wheelchair two classes, wherein, the advantage of manual wheelchair is that simple structure, cost are more cheap, and carry easily, but needing to be promoted or rotated wheel body by user itself with both hands and advance by other people, get off easily to make user tired or need be taken care of with side by another people for a long time, is this class manual wheelchair inconvenience part; On the contrary, the design of electric wheelchair is to utilize motor to drive wheel body to advance, and the rotating speed that user only need be controlled motor gets final product, so can exempt the inconvenience that user need rotate wheel body, does not also need another people to take care of on the side, and this is the advantage place of electric wheelchair.But general electric wheelchair all must cooperate its proprietary drives structure to do holistic design, thus the electric wheelchair structure of each producer be not quite similar, and with general manual wheelchair can't be general, and cost also to exceed manual wheelchair many.Therefore, select manual wheelchair when the user initial stage because of the demand on using or because of the factor on the price, in the time of then need being replaced by electric wheelchair because of the demand change again, because manual wheelchair is different with the electric wheelchair structural design, can not be directly by manual wheelchair repacking upgrading to electric wheelchair, cause user to abandon or to keep old manual wheelchair and buy brand-new electric wheelchair and use, cost thereby increase.

Summary of the invention

The purpose of this utility model provides a kind of can directly being installed on the general manual wheelchair, and manual wheelchair is possessed the electronic die set of driven by power function.

The technical solution of the utility model is: a kind of electronic die set for the wheelchair use, and it comprises:

At least two driving devices, described each driving device comprise that a motor and connects the actuated element group of motor;

One power supply device is an accumulator, is connected to described two driving devices;

One control device is to link to each other with described motor.

The utlity model has two includes a motor and and connects the driving device of this motor with the actuated element group of transferring power, can be individually fixed in the both sides of wheelchair chair frame and make this actuated element group drive corresponding wheel body and rotate, and has a power supply device that an accumulator is constituted, can be placed on the chair frame of wheelchair so that required electric power to be provided, user can utilize one be positioned on the chair frame control device with control motor rotary speed, so can not need revise the structure of original manual wheelchair, and directly install said apparatus additional and upgrade to electric wheelchair, reach the purpose of saving expenditure.

This utility model comprises at least two driving devices, a power supply device and a control device, this driving device includes a motor and and connects the actuated element group of this motor with transferring power, can be individually fixed in the both sides of chair frame and make the actuated element group drive corresponding wheel body and rotate, power supply device then can place on the chair frame, and be connected to two driving devices with the supply driving device the motor required electric power, again by control device in order to control the motor rotary speed of each driving device.

Below in conjunction with specific embodiment this utility model is described further.
