[specific embodiment]
Effect for enabling to be easier to understand structure of the present invention and can reach cooperates graphic being described as follows now:
At first, see also shown in Fig. 2,3, electric wheelchair 2 of the present invention has a seat 3, a support unit 4 and a vehicle frame 5 at least.
Seat 3, the tool chair cushion 31 and the chair back 32, be provided with handrail 33 by chair cushion 31 rears along the chair back 32 2 sides, wherein, forward and backward two ends in chair cushion 31 bottoms are installed with first connector 34 and second connector 35, and these first connector, 34 central authorities are provided with a sleeve pipe 341, and this sleeve pipe 341 is provided with screw thread 3411 in the inside at proximal end place, can make locking screw 43 be arranged on the sleeve pipe 341 whereby, and this sleeve pipe 341 is to be vertical setting with seat 3; These second connector, 35 central authorities are provided with an axostylus axostyle 351, and this axostylus axostyle 351 is to be horizontally set with seat 3.
Support unit 4 includes first pole 41 and second pole 42;
Please cooperate shown in Figure 3 again, vehicle frame 5 is the support bodys in order to supporting chair 3, these vehicle frame 5 front and back are respectively equipped with first and adjust the pipe 51 and second adjustment pipe 52, this first adjustment pipe 51 is to give sheathed for first pole 41, and these first adjustment pipe, 51 perforation 511 that are provided with corresponding to the screw 411 of first pole 41 can utilize bolting element S that first pole 42 is locked in first whereby and adjust on the pipe 51; Second to adjust pipe 52 be to give sheathedly for second pole 42 for this, and this second adjusts pipe 52 perforation 521 that are provided with corresponding to the screw 421 of second pole 42, can utilize bolting element S that second pole 42 is locked in second whereby and adjust on the pipe 52.
The present invention is when implementing, be earlier first pole 41 of support unit 4 and second pole 42 are arranged in first on the vehicle frame 5 adjust pipe 51 and second adjust manage 52 after, S locks it with bolting element, then the axostylus axostyle 351 of second connector 35 of chair cushion 31 belows is inserted in the guidance part 422 along the guide channel 423 of second pole 42, because guide channel 423 upper surfaces are to be an inclined-plane, therefore axostylus axostyle 351 is slipped in the guidance part 422, as Fig. 7 A, shown in the 7B, again the sleeve pipe 341 of first connector 34 is placed on the groove 413 of first pole, 41 placing parts 412 afterwards, and pass sleeve pipe 341 with locking screw 43 spiral shells, the end that locking screw 43 spiral shells pass sleeve pipe 341 just can penetrate in the fixing hole 415 of barricade 414 of placing part 412, the front end of locking screw 43 hole 415 that can be fixed is limited and can't be moved again, as Fig. 6 A, 6B, 7A, shown in the 7B, the front and back of seat 3 are promptly respectively by axostylus axostyle 351 and guidance part 422, and lockhole 415 restrictions of locking screw 43 and placing part 412, simultaneously because locking screw 43 is to advance to second connector, 35 direction spiral shells, and can force axostylus axostyle 351 more to recline to the rear end of guidance part 422, can make seat 3 on vehicle frame, obtain stable location whereby, can finish combining of seat 3 of the present invention and vehicle frame 5 by above-mentioned action.When desire is done maintenance to the miscellaneous part of seat 3 belows, only need to rotate locking screw 43, make locking screw 43 in sleeve pipe 341 to outer back-out, and make locking screw 43 former ends that penetrate lockhole 415 withdraw from, this moment, limited in locking screw 43 hole 415 that no longer is fixed, whereby, because the axostylus axostyle 351 of 3 surplus rear ends of seat and the restriction of guidance part 422, and because effects such as the chair back 32, make the center of gravity of seat 3 in the rear end, therefore no longer be fixed hole 415 when limiting when locking screw 43, seat 3 is pivot point with axostylus axostyle 351 with guidance part 422, and seat 3 can be automatically to layback, and then can make seat 3 raise automatically, reach the convenience of maintenance miscellaneous part, after seat 3 is raised automatically, can pull by the top of top supporting part 424, the angle of avoiding seat 3 to raise is excessive.
See also again shown in Fig. 8,9, electric wheelchair 2 of the present invention is when adjusting the high and low position of seat 3, only need bolting element S is taken off, this moment, first pole 41 and second pole 42 can be adjusted the action of carrying out lifting in the pipe 52 by the first adjustment pipe 51 and second on vehicle frame 5, with seat 3 liftings to desired location, with bolting element S it is locked again, can reach the purpose of adjusting seat 3 high and low positions.
Effect of the present invention is to have a placing part 412 by these first pole, 41 tops, and this placing part 412 is provided with groove 413 and fixing hole 415, can be ccontaining for the sleeve pipe 341 of first connector 34 of chair cushion 31, relend that to wear lock by locking screw 43 fixing; And the guidance part 42 of these second pole, 42 tops, this guidance part 422 is provided with a guide channel 423, this guide channel 423 can make the axostylus axostyle 351 of second connector 35 enter smoothly in the guidance part 422, and by the locking screw 43 that rotates first connector 34, make locking screw 43 hole 415 that no longer is fixed limit, axostylus axostyle 351 that promptly can second connector 35 is a pivot point, can easily seat 3 be raised, this moment, the top supporting part 424 at these second pole, 42 guidance parts, 422 rears can be resisted against chair cushion 31, and can avoid the reclining angle of seat 3 excessive, can conveniently change the action of battery or maintenance.
Of the present invention time an effect is, is to be an inclined-plane by guide channel 423 upper surfaces, when seat 3 desire groups stand on the vehicle frame 5, can make axostylus axostyle 351 slip into easily in the guidance part 422, can improve 2 groups of upright conveniences of electric wheelchair.
In sum, the present invention really can effectively improve the disappearance of known electric wheelchair seat by above-mentioned structure, has not comparatively commonly used the person and has promoted effect.
