Detailed description of the invention

One, critical piece.

As shown in Figure 4, this utility model includes mounting 1, road wheel 2, bracing frame 3.

1, mounting.

As shown in Figure 1 and Figure 2, described mounting 1 is rectangular, and added is seat board 11, lower for munnion 13, its mount structure be upper, Being fixed with vertical tube between lower two square single frames being fixed connection by longitudinal and transverse bar two ends, the height of munnion 13, to be layered in mounting Height required for placing two overlaps road wheel 2 together and determine, the corresponding upper and lower end both sides, both sides of munnion 13 are respectively Being provided with rotation adaptor 14, holding firmware 15, adaptor includes rotating shaft 141 and transposase 11 42 or connecting rod 143 and sleeve pipe 144, holding firmware Including snib 151 and hole clipping 152 or button fasten 153 with Button Block 154, the road wheel 2 because being placed in munnion have nexine, outer layer it Point, the adaptor of both sides, holding firmware upper-lower position are the most different, are placed on the road wheel side frame 21 of nexine and the munnion 13 of homonymy, on End both sides set adaptor 14, and both sides, lower end set holding firmware 15, put road wheel side frame and the munnion of homonymy of outer layer, and both sides, upper end set Holding firmware, both sides, lower end set adaptor, and the side frame 21 of nexine, outer layer parallel storing respectively with both sides munnion 13 intersection is exactly The nest point of adaptor 14, is provided with bullet support spring at adaptor, road wheel can automatically open up vertically under elastic force effect, and road wheel erects Time straight, the distance of seat board both sides to ground is equal, and when folding storing, the distance between seat board and innner and outer layer road wheel is suitable, perpendicular Leaving opening 131 before frame, the road wheel front-wheel 24 for nexine exposes frame external, is provided with gear at the holding firmware of munnion 13 both sides Plate 16, is easy to fix for limiting the vertical angles of road wheel, to keep vertical with seat board 11.

As shown in Figure 1, Figure 2, Figure 4 shows, described seat board 11 rear end thereof connects backboard 12, its backboard and seat board geomery phase Correspondence, backboard both sides are provided with card article 121, corresponding with the slotted collar 252 of handrail 25 rear end, and backboard also can with seat board activity even Connecing, separable seat board is placed in before and after munnion lower end in the clip slot on frame limit, and such mounting two sides is that tabular boxlike is the same more Beautiful.

2, road wheel.

As shown in Figure 1, Figure 2, Figure 3, Figure 4, road wheel 2 includes side frame 21, front-wheel 24, trailing wheel 23, and described side frame is by fixing The cross bar that connects, the single frame of montant composition, be in its upper end of side frame 21 that nexine puts and set adaptor 14 lower end and set holding firmware 15, Being in its lower end of side frame that outer layer puts and set adaptor, upper end sets holding firmware, corresponding with the adaptor of munnion, holding firmware, side In the middle of frame, bottom be fixed with cross bar, the sleeve pipe 144 of portable plate 22 upper and lower end overlaps respectively and is through on two cross bars and horizontally slidable, Portable plate lower end is fixedly connected with vertical axostylus axostyle 221, and axostylus axostyle is rotationally connected with trailing wheel 23, and the diameter of trailing wheel is less than seat board 11 Length, when side frame 21 folds, portable plate 22 moves in the middle of frame cross bar, and trailing wheel 23 is built in base frame, when side frame 21 is opened live Moving on to frame limit after dynamic plate 22 and fix, front and rear wheel distance is pulled open.

On front side of side frame as described in Figure 1, lower end is fixing connects boom, and the tube connecting universal front-wheel fixed by its bar, front-wheel Bottom flushes with the bottom of trailing wheel.

3, bracing frame.

As shown in Figure 1, Figure 3, being provided with bracing frame 3 between two side frames 13, it includes folding rod 31, pedal 32, described Folding rod one end connects side, mounting bottom surface, is provided with the hinge of band baffle plate in bar, can limit folding rod and make the folding of 180 degree, separately One end is rotationally connected side frame 21 lower end over there, and when side frame is vertical with seat board, folding rod folding is straight, when side frame is parallel with seat board 11 Folding rod closes, and described pedal is that the boom that two side frame front ends are connected with front-wheel is provided with pedal, and its one end rotates even Connecing a boom, centre is provided with the hinge of band baffle plate, and other end headband catching groove can be buckled on opposite side boom.

Two, mounting and the annexation of side frame.

In general, time in front-wheel 24 and the closest and built-in mounting 1 of trailing wheel 23, its volume is minimum, during expansion, after band The portable plate 22 of wheel moves to the rearmost end of side frame, and when pulling open certain distance with front-wheel the most surely, such wheel-chair just can be stablized not Easily rollover, therefore, case above to be considered during design.

As shown in Figure 1 and Figure 2, rotating shaft 141 and the mounting on its both sides, top of side frame 21 being placed on munnion 13 endonexine are folded The transposase 11 42 on both sides, side munnion 21 upper end is rotationally connected, when side frame is vertical, and the snib 151 on the middle both sides of side frame and mounting Hole clipping 152 phase on both sides, munnion 21 lower end fixes；Folding is placed on its middle sleeve pipe 144 of side frame of munnion outer layer and wears present On the connecting rod 143 of munnion lower end, frame side, when side frame is vertical, the Button Block 154 phase card of the buckle bolt 153 on its top and munnion upper end Gu, vertical side frame upper end flushes with seat board, and both sides seat board is equal to patch length, or the road wheel of both sides is parallel to base plate and divides Stratification is placed in munnion.

As it is shown in figure 1, the handrail 25 that the side frame upper end montant mouth of pipe intubates built with band, armrest rear end is provided with band slotted collar 252, corresponding with the card article 121 on backboard 12 both sides, when side frame 21 is vertical, the middle snap ring alignment of opening of armrest rear end holds up backboard two The card article termination of side, above carries handrail, and slotted collar wears on card article, and open card, at the narrow boards that card article is connected with backboard, is held up Hands rises to correct position and fixes.

Described wheel-chair or be provided with In-wheel-motor driving and control system, battery is arranged on mounting, and front-wheel is equipped with and can control The card handle in direction.
