The specific embodiment
According to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 and shown in Figure 8, the utility model is at original underframe 1, the pulley bracket 2 that fixes with underframe, double-deck transmission bracket 3, the heelpiece supporting base 4 of two bar transmissions is by powered support 8, on the basis of the actuating unit 5 that power rail 18 and motor 9 are formed, the utility model particularly end of transmission bracket 3 is hinged on the transmission support 6 of underframe 1, heelpiece support 7 on the transmission bracket 3 is hinged on forward portion in the heelpiece supporting base 4, the front end of described transmission bracket 3 has the motor 9 in electric machine support 10 and the actuating unit 5 to be hinged, and the powered support 8 and the heelpiece supporting base 4 of actuating unit 5 are hinged.
More than underframe 1 described in the utility model be double-deck rectangular frame support, be fixed with pulley bracket 2 in the frame of its rectangular frame bracket of lower floor, it is suitable with transmission bracket 3 that the middle part of the rectangular frame bracket in upper strata is provided with transmission support 6.
Above-described pulley bracket 2 comprises front wheel portion 11 and rear wheel portion 12, is connected by toggle between front wheel portion 11 and the rear wheel portion 12, and the roller arm of rear wheel portion 12 is provided with rotatable 90 ° spanner 13, and spanner 13 middle parts are provided with fixture block 14; The pulley both sides of front wheel portion 11 are hinged with two inboards, front portion at the rectangular frame bracket of lower floor of underframe 1 respectively, and rear wheel portion 12 pulley both sides are hinged with two inboards, rear portion at the rectangular frame bracket of lower floor of underframe 1 respectively.
Pulley bracket can be by regulating spanner, thereby make pulley lift away from ground or fall to touching mutually with ground, make underframe so that seat support integral body is located ground or built on stilts, make seat be moved easily, concrete operations are as follows: spanner is adjusted to state perpendicular to the ground, fixture block is lived the rear wheel bar with kayser, the rear wheel bar overturn forward and drove rear wheel and routs up forward this moment, make rear wheel turn to forward with ground and contact from lifting away from the state of ground, rear portion with underframe is lifted away from ground then, simultaneously, under the effect of toggle, front wheel bar and rear wheel bar be upset forward together, up to toggle the front wheel masthead is lived, at this moment front wheel is along with the front wheel bar overturns forward, finally turn to contact with ground and the underframe front portion is lifted away from ground; After seat is moved to desired location, only need be with moving 90 ° of spanner counter rotation, this moment, the rear wheel bar did not have obstacle to drive rear wheel immediately to contrary direction upset, make rear wheel lift away from ground, under the effect of toggle, the front wheel bar also along with the upset of rear wheel bar, also makes front wheel lift away from ground, form the seat underframe at last and be seated on the ground, seat then can not at will move.
The heelpiece supporting base 4 of above-described pair of bar transmission comprises cushion rack 15, back bracket 16 and seat fore-stock 17, and wherein the front end of cushion rack 15 is hinged with a fore-stock 17, and cushion rack 15 rear ends are hinged with back bracket 16.Described cushion rack 15 is by supporting plate and be arranged on the inboard cradling piece with the supporting plate balance of supporting plate and form, and wherein cradling piece and powered support 8 fix.Described seat fore-stock 17 is a W type parallel double rods bracket supports pressure pin foremost, wherein the preceding fixed bar in the W type parallel double rods support is hinged on the supporting plate front end, back power rail proximal end place is hinged on the supporting plate, and the position-limitting pin that has power rail on supporting plate, the power rail end then is hinged on cradling piece foremost.Described back bracket 16 is made up of the frame sheet that five build tails link to each other, its middle and upper part is the power rack sheet, the cradling piece end of power rack sheet front end and cushion rack 15 is hinged, the locating rack sheet of bottom then is hinged with supporting plate, and the position-limitting pin that on supporting plate, has the locating rack sheet, have and transition frame sheet that the locating rack sheet is hinged and power rack sheet between be provided with back rest sheet group.
The utility model integral power derives from motor, overall operation is controlled by actuating unit, total event original state such as Fig. 1, transmission bracket is folded in directly over the underframe, the heelpiece supporting base that is hinged on the transmission bracket both sides is contracted on the transmission bracket, the back bracket of heelpiece supporting base and seat fore-stock also are contracted in heelpiece supporting base rear end and front end respectively, powered support hinged end in the actuating unit rests on the positive middle part of power rail, lead to motor at electric current, the motor backwards rotation is also released the powered support hinged end along the power rail end direction gradually, at this moment, cushion rack integral body is to rising, the cradling piece that fixes with powered support is then promoting, and makes the seat fore-stock extend forward, and the W type parallel double rods support edge of seat fore-stock rotates forward the hinged place on cushion rack separately, the maximum anglec of rotation is 85 degree, meanwhile, the power rack sheet of back bracket is promoted rearward to release by cradling piece, makes back bracket integral body backward; When powered support is pushed into nearly power rail proximal end by motor, back bracket at the power rack sheet simultaneously by back thrust influence, the limited pin of locating rack sheet withstands, thereby backrest is rearward rotated, the maximum anglec of rotation is 130 degree.
Only need be with the running of motor forward, aforesaid operations then can be reversed, and after powered support returned back to the positive middle part of power rail, total event was replied original state.
If continue to allow motor forward running, powered support is moved to motor drive direction along power rail, then can make the transmission bracket extension that makes progress, the heelpiece supporting base is vertically upwards lifted.
