The jack horse is in moveable connection with a vehicle body, wherein the so-called moveable connection here does not mean that the jack horse is combined with the vehicle body fixedly or unchangeably, but means that the jack horse is moveable relative to the vehicle body but not separated from the vehicle. The moveable connection is not on the premise of an implementation way.
Description
One, technical field:
The invention belongs to a field of aids for the disabled,
Two, background technology:
The drive slip control way has been revised by the recent year's anecdotes central government, and wherein cheering is to have relaxed the physical qualification that the people with disabilitys such as two lower limb are admitted to driving license, and so a lot of people with disabilitys just can drive motor vehicles legally." opened illegal vehicle capable black road " age of told without the road by wrongful treatment was expected to be finished in the past.But recollectedly think to can't be happy again because these people generally want the roller chair to ride instead of walk, though open car have many-sided benefit will with wheelchair particularly electric wheelchair to bring up to car almost be impossible concerning them.Does the meaning of driving so car if can not wheelchair go out have again how much? because car can only travel and is parked on the parking lot and can not enters indoor public places at car lane.Although some automobile is equipped with wheelchair lifting tables, these cars are generally larger, do not allow simultaneously the people with disability to use such car also must others to assist and can get on the bus even do not belong to people with disability's standard type of driving, and lost so again the motility of certainly advocating peace.Simultaneously automobile of the prior art the weak point such as uses with wheelchair lifting tables ubiquity complex structure, the excessive inconvenience of volume at kart and combustion-motor-driven wheelchairs.How to allow the people with disability be sitting on the wheelchair again can be independently to fall on like a cork just the problem to be solved in the present invention of special cycle for disabled people that car drives car or other types.
Application number is that two applications for a patent for invention of 2008101660658 and 2010100025528 have disclosed two technical schemes that can allow user for oneself wheelchair be loaded onto car, has all used special vehicle frame to solve the horizontal direction orientation problem of wheelchair in these two technical schemes.The some of these vehicle frames yes this car, its particularity make these two schemes not the carriage of very suitable car class use, its scope of application just has certain limitation like this.Can design the more convenient device of the larger usefulness of a kind of scope of application and assist the various vehicles that fall on the wheelchair, starting point of the present invention that Here it is.
Three, summary of the invention:
Illustrate: tricycle (such as the car of three wheels such as combustion-motor-driven wheelchairs), carriage (car is the small-sized passenger car of automatic transmission for example) are referred to as special-purpose vehicle.Manpower wheelchair and electric wheelchair are referred to as wheelchair.Special-purpose vehicle vehicle frame and special-purpose vehicle vehicle body are referred to as car body.Above abbreviation uses in the application's file, except indicating especially.
Allow the people with disability of lower limb disability can be sitting on the wheelchair and band is driven special-purpose vehicle with the wheelchair special-purpose vehicle that easily falls on independently together, what at first will solve is how wheelchair and its user to be sent into special-purpose vehicle together but also will be positioned on driver's the position with settling at one go, user can directly be sitting in once getting on the bus drive special-purpose vehicle on the wheelchair.So believing very narrow same poverty-stricken of parking space of adding in space in the special-purpose vehicle as you know wants wheelchair directly to open special-purpose vehicle to be impossible, to have adopted a distinguished technical scheme for head it off the present invention designs.General knowledge tells that we will be an object localization in the local time that particularly vertical height be also different somewhere, and mobile this object in vertical direction again when we should move this object in the horizontal direction can be positioned at it the place of appointment.In like manner will the wheelchair that carries on the ground user be positioned at driver position on the special-purpose vehicle just need satisfy simultaneously vertical direction move wheelchair and horizontal direction move this two large condition of wheelchair could success.We have arranged a mechanical lifting gear and a stand between special-purpose vehicle and wheelchair in the technical program in order to satisfy above-mentioned two large conditions, this stand and application number are that the movable carriage of using in 2010100025528 the application for a patent for invention is different, it is not the some of car body, just for mobile wheelchair in the horizontal direction, do not want again to change original vehicle frame and increase and install, it and mechanical lifting gear equally are " go-betweens " between wheelchair and the special-purpose vehicle.Directly or indirectly the wheelchair that carries user is risen to predetermined height with mechanical lifting gear, directly or indirectly locate with the place that this wheelchair horizontal direction that carries user moves to appointment with stand again.This place can be that driver's position also can be the member position of non-driving, the normal position that this position makes again stand reset.This is basic ideas and method that the present invention is used to overcome the above problems.The normal position that so-called stand resets refers to get back to long its place of parking after stand is finished the work of picking wheelchair, and this place just is defined as the normal position that stand resets.Be not difficult to find out that the wheelchair positioning table that the present invention is contained on the special-purpose vehicle does not have special specification requirement to vehicle with to the position of installing, when it is installed in the avris of position of driver, just can be positioned at wheelchair the below of position of driver.For example when copilot or recoil passenger's avris, it also can be positioned at wheelchair the below of the position of non-driver when it is contained in the avris of non-driver position, and at this moment the normal position that resets of stand has also become the below of the position of non-driver.
The technical scheme that can reach above-mentioned effect is very many, mainly is stand with composition mechanical lifting gear different and to some extent difference different from the horizontal anomalous movement mode of connection of car body in these technical schemes.For example stand uses guide rail, pulley to cooperate the mode and the direct horizontal anomalous movement of car body that are installed on the car body to link together as shown in figures 1 and 3; Stand is hinged on the car body, links together such as Fig. 7, shown in Figure 8 with hinged mode and the direct horizontal anomalous movement of car body.Stand can also be hinged on the mechanical lifting gear and link together by mechanical lifting gear and the indirect horizontal anomalous movement of car body.Mechanical lifting gear is by the indirect lifting wheelchair of stand such as Fig. 9 and shown in Figure 10 etc.No matter how realize that it all is to allow stand can make the horizontal anomalous movement of certain rule with respect to car body that horizontal anomalous movement links final purpose, and by the horizontal anomalous movement of stand the wheelchair that carries user be positioned on the position of horizontal direction appointment.Certain horizontal anomalous movement is not only limited to the straight line horizontal movement and also comprises arc line shaped horizontal anomalous movement or other shaped form horizontal anomalous movement.The vertical direction of wheelchair location is transferred to mechanical lifting gear and is gone to finish, and mechanical lifting gear refers to that here main purpose is used for the combination of machine components that direct or indirect lifting carries the wheelchair of user.So not have again special requirement to be adapted at mechanical lifting gear used herein to lowering or hoisting gear many for the weight of the wheelchair of user and not bery heavy and this lifting platform owing to being seated, the mechanical lifting gear of nearly all form can use.For example manually and electric screw, manual and electric hydraulic, direct-lifting and hoistable platform formula etc.Mechanical lifting gear can be contained on the stand and also can directly be contained on the car body, and its variation is diversified equally.Stand can use different mechanical lifting gears from each horizontal anomalous movement mode of connection of car body simultaneously.
Being that direct or indirect horizontal anomalous movement links between stand and the car body, is direct or indirect flexible connection between wheelchair and the stand.It is not changeless combination that so-called horizontal anomalous movement is attached at the combination that refers to stand and car body here, and their combination is that stand can be made relative horizontal anomalous movement with respect to car body but the combination that can not separate.So link not in the mode that realizes as prerequisite owing to can realize very many this horizontal anomalous movements of mode that this horizontal anomalous movement links, be exactly the horizontal anomalous movement link that the present invention proposes as long as stand meets stand with respect to making relative horizontal anomalous movement between the car body with the combination of car body.The flexible connection that so-called wheelchair activities is connected on the stand here is for the permanent or semipermanent connection of various welding, bolt connection etc., between wheelchair and the stand neither forever be connected and neither semipermanently connect.Here said flexible connection refers to that can directly or indirectly load onto easily stand to wheelchair goes temporarily to combine, and can unload down like a cork with it again and separate.
Be not identical such as Figure 13, Figure 14 and shown in Figure 15 in the shape of different horizontal anomalous movement mode of connection, different installation site and different lifting form lower stage, also being difficult to specify it is any pattern, and it must cooperate the environment of installing and change.Even so but it a very large feature is arranged is exactly that stand can be done relative horizontal movement with the special-purpose vehicle car body, it can both move and be positioned at the place of appointment directly or indirectly on which type of position of which type of car as horizontal direction with the wheelchair that is parked in the special-purpose vehicle outside no matter it installs to simultaneously, the opposite wheelchair that it enough will be positioned at again in the special-purpose vehicle is sent outside the special-purpose vehicle, that is to say that the horizontal movement scope of stand can be by the special-purpose vehicle inner face to the special-purpose vehicle outside.
Wheelchair is service object of the present invention, no matter it to be Manual-pushing or electric power promote wheelchair as long as its volume energy by special-purpose vehicle accept to be equipped with it simultaneously for the positioner that can be flexibly connected with the present invention such as locating hole 25, wheelchair under locating hole on the wheelchair 24, the wheelchair after the present invention such as lock hole 26, wheelchair prelocalization pin 27 and bearing 29 can both be positioned at it the place of appointment.The left side that is installed in wheelchair that these device bases have under the different installation site of different vehicles, the right that is installed in wheelchair that has, this and wheelchair itself have nothing to do.Should use the application of the comparatively suitable institute of electric wheelchair from purpose of the present invention is as example with electric wheelchair.

Its work process is that the user of wheelchair is being opened wheelchair 23 and from special-purpose vehicle rear flank of the present invention face approaching special-purpose vehicle is housed, open electric traction device that car door and starting is comprised of traction electric machine 34 grades by remote control unit and drive stand 4 and stretch out car and stop to the stop of setting outward, at this moment further approaching stand 4 is as shown in Figure 1 for wheelchair.Then user can be by small size movable stand 4 about the remote control electric traction apparatus, the walking function of roller chair slightly moves forward and backward wheelchair 23, makes that upper ferrum 17 on the elevating lever 6 that is contained on the stand 4 colludes, lower ferrum colludes on 18 wheelchairs of aiming on the wheelchairs 23 locating hole 25 under locating hole 24, the wheelchair.And then elevating lever 6 is moved up to catch on wheelchair together to rising as shown in Figure 2 with hand shaking.At this moment the bearing 29 that is contained in the wheelchair side touches baffle plate 42, slides at baffle plate 42 at the process middle (center) bearing 29 that rises and has effectively prevented wheelchair the rocking of horizontal direction in uphill process.When wheelchair rises to user when being higher than the car flooring starts the electric traction device again by remote controller traction electric machine 34 counter-rotatings, by traction screw 30 stand 4 is retracted while closed door in the car together with wheelchair 23, at this moment this wheelchair 23 of carrying user just is positioned in driver's position, and at this moment the position at stand 4 places is exactly the position that normally resets.Further fixing wheelchair 23 rear user by mounted in a vehicle clamp device more just can drive to set out on a journey.Arrived and repeated above-mentioned anti-process after the destination and wheelchair 23 is put back in the special-purpose vehicle car fallen to the ground, wheelchair 23 just can break away from special-purpose vehicle and freely loosed this moment.
This routine horizontal anomalous movement mode of connection can be used on the tricycle as shown in Figure 3, and the operation principle that is used on the tricycle is substantially the same with operation principle on being used in carriage, does not do here to state more.Different place shown in Figure 3 and shown in Figure 1 is that its mechanical lifting gear has changed the motor machine lowering or hoisting gear into by the armstrong's patent lowering or hoisting gear, and the operation principle of motor machine lowering or hoisting gear all is the same on structure or operation principle with aforesaid electric traction device.It is comprised of lifting motor 14, electric screw 36, gear mesh 38 etc. and is installed on the support 35 more logical support 35 and is installed on the stand 4.Gear mesh 38 is a pair of meshing gear together equally, and the power output shaft of lifting motor 14 is fixedly mounted on one of them gear, and electric screw 36 sides are fixedly mounted on another gear.The power of lifting motor 14 passes to electric screw 36 by gear mesh 38, and electric screw 36 and female elevating lever 6 Screw assemblies of processing are together.When user rotates with remote control unit control control lifting motor 14, rotate by gear mesh 38 driving electric screw rods 36, the rotation direction that elevating lever 6 is being followed electric screw 36 under the effect of screw thread is moved up or down, so because wheelchair 23 is that this motion of colluding on elevating lever 6 has also driven wheelchair one lifting, reached the purpose of electric up-down wheelchair.
This routine horizontal anomalous movement mode of connection can also use another kind of lowering or hoisting gear such as Fig. 4, Fig. 5, shown in Figure 6.Stand remains by pulley and guide rail horizontal anomalous movement and is attached on the car body, and the part of the structure of stand such as mounting guide rail and pulley is with shown in Figure 13 identical, and different just up-down modes change indirectly lifting platform mode into by direct lifting.One side of platform 21 is hinged on the stand 4 by table-hinges 12, and another side can swing up and down around table-hinges 12.The motor machine lowering or hoisting gear is comprised of support 35, elevating lever 6, electric screw 36, gear mesh 38, lifting motor 14 etc. and installs on the stand 4 by support 35.One end of elevating lever 6 is hinged on the platform by lifting table-hinges 33, the other end be processed with female thread and with electric screw 36 Screw assemblies together.Gear mesh 38 is a pair of meshing gears together, the other end of electric screw 36 is fixedly mounted on one of them gear of gear mesh 38, the output shaft of lifting motor 14 is fixedly mounted on another gear of gear mesh 38 and both is fixedly mounted on the vehicle frame by support 35, (this point all motor machine lowering or hoisting gear in this paper is all the same).When lifting motor 14 rotated by gear mesh 38 driving electric screw rods 36, elevating lever 6 and platform 21 followed the rotation direction of lifting motor 14 to move up and down as shown in Figure 4 together under the effect of screw thread.
Its work process is that wheelchair 23 can be opened upper mounting plate 21 when platform puts down.The front stop pin 27 of wheelchair is equipped with in the wheelchair front lower place, lower hole 26 is locked referring to Figure 11, shown in Figure 12 after having wheelchair in the back lower place.Be equipped with on the platform 21 that front ferrum colludes 15, location-plate 32, rear ferrum collude 16 and draw fly 19 etc. referring to shown in Figure 5.Location-plate 32 is iron plates that are processed with V-shaped groove, and front ferrum colludes 15 and is hinged on above the location-plate 32 and by spring and pulls on one side, and front ferrum colludes 15 and is connected to wheelchair release lever 20 by stay cord 19.Pulling wheelchair release lever 20 can open front ferrum by stay cord and collude 15 chairs and discharge 23.The prelocalization pin 27 of wheelchair 23 is aimed at the V-shaped groove of location-plates 32 when wheelchair is opened upper mounting plate, can advance according to the guiding of location-plate 32V shape groove so the front-wheel of wheelchair is the prelocalization pin 27 of universal wheel wheelchair.The prelocalization pin 27 of wheelchair 23 is just colluded 15 by front ferrum and catches on when continuing forward.So behind the wheelchair behind the aperture ratio of lock hole 26 ferrum collude behind the 16 large wheelchairs lock hole 26 and be easy to be colluded 16 by the rear ferrum on the platform 21 and catch on.Then user is drawn high with the wheelchair 23 that carries user together by remote control unit startup lifting motor 14 turning handle platforms 21.After reaching predetermined altitude, close lifting motor 14, start the position that traction electric machine 34 retracts together the car middle position of the interior or tricycle of car to stand 4, platform 21, the wheelchair 23 that carries user and is positioned at the driver, at this moment stand 4 residing positions are exactly so-called resetting in positive normal position.
Applicable this routine mechanical lifting gear also has hydraulic machinery lifting device etc.Oil cylinder 40, company 43 are hinged between stand 4 and the platform 21 in the original place that mechanical lifting gear is installed as long as remove original mechanical lifting gear, also can be installed in oil cylinder 40, company 43 between stand 4 and the elevating lever 6.Then connected pipes, oil pump and valve get final product.The flexible lifting that can realize wheelchair by oil pump and valve control link.
Though what remark additionally is that this example has installed a retractable universal wheel 39 additional such as Fig. 5, shown in Figure 6 at stand 4 for avoiding because centre-of gravity shift produces rollover when being applied on the tricycle especially.This universal wheel will be opened at stand 4 and manually is lowered on the ground by user in advance before stretching out, in the process that stand 4 is opened by universal wheel increase to stand 4 to support, make car load can keep balance.Treated on the wheelchair platform and risen to predetermined altitude such as Fig. 4, shown in Figure 6, perhaps wheelchair has directly been risen to predetermined altitude such as Fig. 3, packed up again after stand 4 horizontal resets have arrived the normal position.
Example 2, stand 4 are hinged on the car body 1 by frame hinge 13, link together with car body 1 direct horizontal anomalous movement, and wheelchair 23 directly is movably connected on the stand 4.
The horizontal anomalous movement of stand and car body links also can be realized as shown in Figure 7 and Figure 8 with hinged method.Stand 4 has become 1 font (overlooking) by the T font of example 1 in this example, its first half rectangular latter half of be a triangle as shown in figure 14, mechanical lifting gear remains and is contained in platform and adds.Stand 4 is to be hinged on the car body 1 by frame hinge 13, so stand can rotate around frame hinge 13.Its structure of motor machine lowering or hoisting gear, operation principle and dash number are housed employed the same with example 1 on the stand 4.The electric traction device that this example is used and example 1 employed its structure, operation principle are all the same with dash number, more than different from example 1 is between motor machine lowering or hoisting gear and stand 4 draw bar 22.One end of draw bar 22 be hinged on the stand 4 other end be processed with female thread and with traction screw 30 Screw assemblies together, the electric traction device is hingedly mounted on the car body.When traction electric machine 34 drives traction screw 30 rotation by gear mesh 38, draw bar 22 can push-and-pull stands 4 be made horizontal direction around frame hinge 13 and is rotated and open and close under the effect of screw thread, moves horizontally the horizontal location that just is used on wheelchair 23 in the opening and closing process.
Its work process is that the user of wheelchair is being opened wheelchair and from special-purpose vehicle rear flank of the present invention face approaching special-purpose vehicle is housed and opens car door by remote control unit and start traction electric machine 34 and drive traction screws 30 by gear mesh 38 and rotate, and draw bar 22 promotes stands 4 and rotates and stretch out that the stop to setting stops outside the car under the effect of screw thread.At this moment wheelchair further approaching stand 4 see Fig. 7 and shown in Figure 8.At this moment swing slightly about user can be controlled stand 4 and does by remote controller that the walking function that cooperates wheelchair moves forward and backward slightly that wheelchair 23 can make that upper ferrum colludes 17, lower ferrum colludes on the wheelchair of aiming in addition on the wheelchair 23 in 18 minutes under locating hole 24, the wheelchair locating hole 25 and opens then that lifting motor 14 catches on wheelchair and up promote.The bearing 29 that is contained in the wheelchair side in this process touches baffle plate 42, and slides at baffle plate 42, and it can prevent effectively that wheelchair from producing rocking of horizontal direction in uphill process.The wheelchair 23 that user is restarted electric traction device counter-rotation pulling stand 4 by remote closing lifting motor 14 and carried user when wheelchair rises to predetermined altitude horizontally rotates to the direction in the car resets in the normal position stand, and at this moment user just can drive to set out on a journey after clamp device on the special-purpose vehicle further tightens up admittedly good wheelchair 23 with being contained in.Arrived and repeated above-mentioned anti-process after the destination and wheelchair 23 is put back in the special-purpose vehicle fallen to the ground, wheelchair 23 just can break away from special-purpose vehicle and freely loosed this moment.
Can be used for this routine mechanical lifting gear and also have hydraulic machinery lifting device etc.Oil cylinder 40, company 43 are installed between stand 4 and the elevating lever 6 in the original place that the motor machine lowering or hoisting gear is installed as long as remove original motor machine lowering or hoisting gear, then connected pipes, oil pump and valve get final product.The flexible lifting that can realize wheelchair by oil pump and valve control link 43.Also can change the motor machine lowering or hoisting gear of original installation into the armstrong's patent lowering or hoisting gear as removing original motor machine lowering or hoisting gear, between elevating lever 6 and stand 4, load onto hand screw 10 and load onto crank 11 at hand screw 10 and get final product.
This example is same as Example 1, has installed a retractable universal wheel 39 additional as shown in Figure 7 at stand 4 for avoiding especially because centre-of gravity shift produces rollover when the present invention is contained on the tricycle.This universal wheel is put down on the ground by the user manual unlocking when the stand 4 at wheelchair, in the process that wheelchair is raised by universal wheel increase to stand 4 to support, make car load can keep balance.After resetting to the normal position with wheelchair 23, manually packed up by user again by stand 4.
Example 3, stand 4 are hinged on the mechanical lifting gear by frame hinge 13, and mechanical lifting gear is contained on the car body 1, stand 4 by mechanical lifting gear indirectly and car body 1 horizontal anomalous movement link together, wheelchair 23 directly is movably connected on the stand 4.
This example is that stand is attached on the car body by the mechanical lifting gear horizontal anomalous movement, and this is that an indirect horizontal anomalous movement links referring to Fig. 9, shown in Figure 10.This example and the different places of above-mentioned two examples are that mechanical lifting gear is not to be contained on the stand but to be contained between car 1 body and the platform 4, the shape of stand 4 is similar but also different to the shape of example 2 employed stands, thus this routine stand 4 do not fill upper ferrum that lowering or hoisting gear is used for catching on wheelchair collude 17 and lower ferrum collude 18 and change into and being welded on the stand 4 as shown in figure 15.This routine employed tool lowering or hoisting gear mainly is comprised of riser guide 28, lifting pulley 7, pulley bracket 41, oil cylinder 40, connecting rod 43 etc.Riser guide 28 is comprised of two steel pipes and is fixedly mounted on the car body 1, and two lifting pulleys 7 of riser guide sandwich are up and down distribution, and the face of cylinder of lifting pulley 7 is processed with arcuate groove and can be combined together well with riser guide 28.Frame hinge 13 is housed on the pulley bracket 41, stand 4 is hinged on the pulley bracket 41 by frame hinge 13, pulley bracket 41 is installed on the axis of lifting pulley 7, and therefore lifting pulley 7 can slide up and down platform in the riser guide 28 and add 4 and also can follow the oscilaltion campaign as shown in Figure 9.Oil cylinder 40 is fixedly mounted on that connecting rod 43 is fixedly mounted on the pulley bracket 41 on the car body.When making stretching motion under the driving of connecting rod 43 at oil pump, also move up and down with pulley bracket 41, lifting pulley 7, frame hinge 13, stand 4 etc.Stand 4 can horizontally rotate around frame hinge 13.This example also can move both vertically when having a special feature stand 4 both can move horizontally, and the draw bar 22 that therefore promotes its opening and closing should bear to horizontally rotate and bear again vertical rotation.In order not adopt simple hinged between this needs draw bar 22 of satisfying it and the stand 4 but adopt spherical plain bearing rod end to be connected.This bearing can bear and also can bear certain vertical rotation when horizontally rotating just as a joint.One end of draw bar 22 links together by spherical plain bearing rod end 31 and stand 4, traction screw 30 Screw assemblies that the other end is processed with female thread and electric traction device together, same employing spherical plain bearing rod end is connected between electric traction device and the car body.Stand 4 just can be like a cork even is side by side done to horizontally rotate and elevating movement like this.
