Description
Technical field
This utility model relates to a kind of wheelchair drive mechanism, particularly relates to a kind ofly having quick detach clamping structure, and has and can make wheelchair front wheel unsettled and reach and prevent the wheelchair drive mechanism of jolting when wheelchair is advanced.
Background technology
The propelling wheelchair that existing electric wheelchair can allow wheelchair user work hard, and can solve the difficult problem of going up a slope.Yet electric wheelchair is bulky, gross weight is between 30 to 50 kilograms, and difficult long journey goes out to carry, so just there is on the market a kind of wheelchair tractor of pull-type; Known tractor is installed in wheelchair the place ahead in plug-in mode, and user needs only starter, and just interlock wheelchair is advanced easily, and removable separate design, and user is easy to go out to carry, and gross weight is between 15 to 25 kilograms.
Yet, existing wheelchair tractor and wheelchair integrated structure are complicated, though be removably design, but be all the design of spiral shell group or plug-in unit insert group, sometimes need on wheelchair, install the extra accessory such as cross bar additional and cause the weight still cannot lightweight, and mounting-dismounting programme is complicated, time and effort consuming be not portable, some even causes wheelchair cannot close up folding, loses the function that it is taken in.
In view of the disappearance of prior art, this utility model improve existing mounting-dismounting programme complicated with weight and take in inconvenient shortcoming, facilitate body barrier or handicapped person.
Utility model content
Main purpose of the present utility model is to improve existing wheelchair tractor volume heaviness, complex structure, the difficult shortcoming of its dismounting, and for reaching above-mentioned purpose, concrete content of the present utility model is:
One control unit, comprises a tap and connects a standpipe, and these tap two ends are respectively provided with leader; Above-mentioned standpipe group connects a front fork; Be located at leading v brake structure for two; One is located at starting switch and a gauge tap of grip, and this starting switch and this gauge tap and main control system are electrically connected;
One driver element, comprises the motor that a battery and is located at the wheel shaft place of a wheel, and this wheel and this motor are hubbed in the front fork of above-mentioned control unit;
One fixed cell, comprises at least one fixed mount, and this fixed mount is provided with at least one movable joint; One spiral shell group is in the clip structure at these fixed mount two ends, and this clip structure is pulled portion, one first buckle portion and one second buckle portion by a fit portion, and formed; This portion of pulling connects the first buckle portion, and this pulls portion's mat 1 the 3rd pivot and this fit portion is articulated, and this first buckle portion mat one first pivot and this fit portion are articulated, and this second buckle portion mat one second pivot and this fit portion are articulated; This first buckle portion and this second buckle portion can be interlocked; And
One adjusts and to stick up unit, the ratchet structure that comprises the standpipe place that is located at described control unit, the fixed mount of this ratchet structure and the above-mentioned fixed cell group that is nested; This ratchet structure has a forward switch and a reversal switch, and this forward switch and this reversal switch can be controlled the ratchet forward or reverse in ratchet structure.
The concrete effect of this utility model is when user wish is moved running wheel chair with this utility model, user can be opened the clip structure of fixed cell, and the fit portion of clip structure is sleeved on to the support body of wheelchair, allot again afterwards after the first buckle portion and the second buckle portion make it to be interlocked, user again switching this pull portion, making the first buckle portion and the first pivot take the 3rd pivot is fulcrum, towards the displacement of switching direction, make the second buckle portion towards the closing of fit portion, lever principle by this, user is can be easily effortless to be closely buckled in clip structure on the support body of wheelchair.
After clip structure is clamped on the support body of wheelchair, user first sticks up tune the forward switch opens of unit, make ratchet structure be forward state, pass again afterwards the handle of control unit, tap is hastened forward, and the fixed mount of interlock fixed cell pushes away support by the support body of wheelchair, make the front-wheel of wheelchair be suspention shape.
Mat is adjusted and is stuck up unit by the suspended on front wheel of wheelchair, and after the bolt that is locked, user just can start the starting switch of control unit, order about motor start and advance, and the member such as tap, gauge tap and brake structure that can mat control unit is controlled the actions such as advancing, retreat, turn, accelerate, slow down and stop of wheelchair.The front-wheel of wheelchair is suspention shape, is the state that three-wheel contacts to earth after this utility model is combined with wheelchair, is difficult for having the situation of serious vibrations to occur while making to advance.
When user is wanted to unload this utility model, first turn-off ratchet gim peg, the reversal switch that then tune is stuck up to unit is opened, and makes ratchet structure be inverted status, and then the front-wheel of wheelchair is contacted to earth, and is returned to five of script and takes turns the state contacting to earth; Light dialling pulled portion afterwards, can make the first pivot take the 3rd pivot as axle center towards the direction displacement of being stirred, and then the first buckle portion and the second buckle portion are got loose, and dismantles easy and light.
This utility model replaces the assembling modes such as known spiral shell group and plug-in unit with clip structure, to tear group program open simple with wheelchair, and dismounting almost all can complete in ten seconds, and adjustable fixed mount design, can be compatible with the specification of commercially available more than 90% wheelchair, moreover wheelchair can fix with this utility model without additionally installing any accessory additional again, very easy in use.
