Abstract

An electric cart changed from a walking stick comprises a cart frame, wheels, a motor, a battery, an operation rod and a cloth stool. The cart can be detached and rapidly assembled into the walking stick, and the walking stick can be detached and rapidly assembled into the cart. The cart frame is the lower framework part of a walking stick framework. The cloth stool forms the upper framework part of the walking stick after being folded. The cloth stool is composed of a stool frame shell, seat cloth and a foot stand, and the foot stand is fixed to the cart frame. The operation rod of the cart is a foot pipe of the walking stick. The rear wheels of the cart are installed at the ends of two telescopic rods pulled out from a lifting handle, and the front wheel of the cart is installed under a connecting pipe. The motor drives the cart to move. When the cart is changed into the walking stick, the motor, the battery, the cloth stool, the wheels, the foot pipe and a handle are taken down, and the telescopic rods are pressed back. The cloth stool is folded, and foot strips are inserted into foot strip boxes and locked. The wheels are hung below the stool frame shell. The foot pipe is screwed on the connecting pipe, and then the walking stick is formed. When a user walks too far by means of the walking stick and has difficulty, the walking stick can be changed into the cart, and then the user can drive the cart to go home. The cart is convenient to store and carry after being changed into the walking stick.

Description

The motor-driven carrier that crutch becomes

Technical field

The invention belongs to the motor-driven carrier that dolly field, particularly crutch become.

Background technology

The dolly that the personnel that now legs and feet have deformity or wound go out all is framework than larger.Passenger will be got off During walking, carriage walking will be also push.When the personnel for leaning on crutch ride, should get on the bus with crutch, will get off and lean on crutch step During row, and also very important person pushes dolly and walks.Particularly much with the rehabilitation personnel in crutch walking, walk far, return and very laborious, Think that by bus some sections often no car brings very big difficulty to the people in rehabilitation.

The content of the invention

It is an object of the invention to provide a kind of Simple small that can be become with crutch, ribbon supply crutch personnel go out tired after the walk , when having walked far to go home difficulty, crutch be quickly assembled into motor-driven carrier, drive to hurry on a journey.

What the present invention was realized in：The motor-driven carrier that crutch becomes, including vehicle frame, wheel, motor, battery, action bars, Cloth stool.Dolly is taken apart and can quickly be assembled into crutch, and crutch is taken apart and can quickly be assembled into dolly.The lower frame connected by carrying handle and two ends Frame, foot barrel, connecting leg constitute the lower frame of crutch framework.The vehicle frame of dolly is made up of the lower frame of crutch framework.Cloth stool It is made up of stool frame shell, seat cloth, foot rest.Cloth stool constitutes the upper frame of crutch framework.The foot rest of cloth stool is fixed in car frame. The action bars of dolly is made up of the foot tube of crutch.Motor is connected with front-wheel.Battery is placed with vehicle frame.Foot is mounted with underframe Barrel, is mounted with knob on foot barrel.Two expansion links that two wheels at dolly rear are pulled out in being arranged on the housing of carrying handle Termination, the wheel in front of dolly are arranged on below connecting leg.After dolly becomes crutch, battery, motor are mounted in bag by entourage Withdraw.After dolly becomes crutch, crutch is made up of upper frame, lower frame, foot tube, seat cloth, end socket.Dolly becomes crutch When, two groups of foot bars of cloth stool are inserted in foot barrel, are locked with knob.After dolly becomes crutch, wheel is hung over below stool frame shell.Stool Frame shell is provided with buckle below.

The motor-driven carrier that crutch becomes, hereinafter referred to as dolly.Dolly is it is necessary to have vehicle frame, wheel, seat stool, can just be called Car.Here what is described is electric motor car, must also action bars, handle etc..The all constituents of dolly, are torn open crutch with one completely Open composition.It is a framework above crutch, framework hereinafter referred to as is crutch top frame.Framework upper end is a bracer, is used for Support is in user oxter assisted walk.Crutch bottom is a foot tube.The seat stool of dolly is a folding cloth stool.Cloth stool is folded It is an ingredient of crutch after gathering, that is, constitutes the upper part of crutch framework.Underframe that carrying handle and two ends are connected, foot Barrel, connecting leg constitute the lower frame of crutch framework.The vehicle frame of dolly is constituted with the lower frame of crutch framework.Have above cloth stool Two horizontal mouldings, i.e. stool frame shell.Seat cloth two ends are connected on stool frame shell.During cloth stool folding, seat cloth is folded and is positioned over stool In frame shell.The foot rest of cloth stool is made up of four foot bars.Be connected below every stool frame shell two foot bars.Wherein one stool frame shell The foot bar connected below two is just put between two foot bars below another stool frame shell.Two adjacent foot bar pins Nail, i.e., rivet is hinged together, and is one group of foot bar.After cloth stool folding, per group of two foot bars can be drawn close side by side.Foot bar is pulled open i.e. Into cloth stool.Foot bar lower end mode connects for screw is in car frame.

Two foot barrels are fixed with the underframe of crutch, the knob of locking action on foot barrel, has been mounted with.Cloth stool is received After folding, two groups of foot bars are separately inserted in foot barrel, twisting knob locking.At this moment, two stool frame shells have been drawn close.Stool frame shell is following Buckle is installed, two stool frame shells are fastened together, this is just into the bracer of crutch framework upper end.

Carrying handle is a hollow pipe, and two expansion links are provided with pipe, and expansion link can be pulled out to carrying handle two ends. There is the shaft part and thread segment for installing wheel expansion link outer end.Two wheels of dolly back are arranged on two expansion link outer ends, use Nut screwing clamping.Crutch lower end is foot tube, and crutch framework is connected together with one section of connecting leg with foot tube.Wheel in front of dolly is arranged on In wheel fork, wheel fork is arranged on connecting leg.Connecting leg is passed through above wheel fork, is linked together with the foot tube lower end of crutch, just into behaviour Make bar.Handle is placed with foot tube.Foot tube upper vertical is provided with through hole.The handle in foot tube is taken out, by handle through in foot tube Through hole, handle on action bars.Handle slightly taper, pushes away in foot tube through hole and fixes.

Cloth stool, wheel, foot tube, handle are removed, expansion link is pushed back.Folding cloth stool, is separately inserted two groups of foot bars of cloth stool Lock in foot barrel.Wheel is hung over below stool frame shell i.e. bracer, and fixed.Handle is put into foot tube, and foot tube is screwed on connecting leg, that is, become For a crutch.

Motor, battery, wheel fork, electric machine support are placed in bag and are withdrawn by entourage.

It is an advantage of the current invention that：1st, motor-driven carrier can be changed into crutch, and crutch can be changed into motor-driven carrier, turn outer to band The people for going out bring great convenience.Turn people and walk far when leaning on, when returning highly difficult, motor-driven carrier can be become with crutch, oneself is driven Car is returned.2nd, the inconvenient people of legs and feet will go out to handle affairs, and can drive to run errands.3rd, after dolly becomes crutch, storage, carrying are very It is convenient.
