Detailed description of the invention
As shown in Figure 3-Figure 5, the present embodiment comprises the folding controlling organization of fore-stock 16, after-poppet 5, front and back support seat 20 and wheelchair frame, wherein:
Described fore-stock 16 and after-poppet 5 upper end thereof are present on rebasing seat 29, and described after-poppet 5 lower end is hinged on described front and back support seat 20, and described front and back support seat 20 is fixed on vehicle frame 26
nullSuch as Fig. 6、Shown in Fig. 7，The lower half of described fore-stock 16 is fork configuration，Described fork configuration is by a left side、Right forks piece 40、41 are constituted，Described fork configuration is across on described front and back support seat 20，It is provided with catch means between described fore-stock 16 and described front and back support seat 20，Described catch means comprises stage clip 17、Alignment pin 18、Slip elongated slot 36、Folding lock-bit groove 22 and stretching, extension lock-bit groove 21，Described slip elongated slot 36 is located at a left side、Right forks piece 40、On 41，Described stage clip 17 is arranged on the cross-point locations of described fork configuration，Described stage clip 17 outer end couples described alignment pin 18，Described alignment pin 18 two ends are arranged on a left side、On right described slip elongated slot 36，Described folding lock-bit groove 22 is located on described front and back support seat 20 corresponding when folding with described fore-stock 16 (see Fig. 4)，Described stretching, extension lock-bit groove 21 is located on described front and back support seat 20 corresponding when stretching with described fore-stock 16 (see Fig. 4)，Described stretching, extension lock-bit groove 21 adopts step notch，Formed by the step outer surface being located on described front and back support seat 20，When making seat machine frame stretching, extension open，Alignment pin 18 can be quick、Find the position stretching lock-bit neatly.
nullFor another example Fig. 3、Shown in Fig. 4，The folding controlling organization of described wheelchair frame comprises button 32、Button seat 30、Foldable linkage bar 19、Three foot clutch 34、Upper linkage piece 33、Lower linkage piece 35、Upper push-rod 28、Lower push-rod 27、Chain 23 and extension spring 24，Described button seat 30 is connected with vehicle frame 26，Described three foot clutch 34 are connected in a described left side、Right forks piece 40、Between 41，Described Foldable linkage bar 19 one end couples described button 32，Described Foldable linkage bar 19 other end couples described three foot clutch 34 first feet，Described three foot clutch 34 crus secundas couple described upper linkage piece 33 one end，Described upper linkage piece 33 other end couples described upper push-rod 28 one end，Described upper push-rod 28 other end withstands on described alignment pin 18 through described stretching, extension lock-bit groove 21，Described three foot clutch 34 the 3rd feet couple described upper linkage piece 35 one end，Described lower linkage piece 35 other end couples described lower push-rod 27 one end，Described lower push-rod 27 other end withstands on described alignment pin 18 through described folding lock-bit groove 22，Described chain 23 one end is connected in the lower end of described fore-stock 16，Described chain 23 other end couples described extension spring 24 one end，Described extension spring 24 other end is connected on described vehicle frame 26.Described extension spring 24 carries out transition with described fore-stock 16 lower end by chain 23 and couples, and solves the location conflicts problem between extension spring and vehicle frame.
When frame is in extended position (shown in Fig. 1, Fig. 3), when needing frame to be carried out folding, button press 32, three foot clutch 34 are pulled to rotate by folding connecting rod 19, in drive, linkage piece 33 and upper push-rod 28 push out, also pull lower linkage piece 35 to be displaced outwardly with lower push-rod 27 simultaneously, upper push-rod 28 overcomes the stretching, extension lock-bit groove 21 that the pressure of stage clip 17 ejects alignment pin 18 on front and back support seat 20, release the lock-bit to fore-stock 16, now fore-stock 16 and after-poppet 5 can be moved up and down, it is achieved folding frame.
When frame is moved downwardly to folding position (shown in Fig. 2, Fig. 5), namely when alignment pin 18 arrives the correspondence position of folding lock-bit groove 22, alignment pin 18 is under the effect of stage clip 17 elastic force, and alignment pin 18, by the folding lock-bit groove 22 of jacking, makes frame be in foldable locking state.Meanwhile, under the effect of stage clip 17 elastic force, alignment pin 18 promotes lower push-rod 27 to move inward, and promotes three foot clutch 34 to rotate counterclockwise by lower linkage piece 35, thus driving button 32 and upper push-rod 28 to reset.
Moving downward in folding process in frame, fore-stock 16 rotates clockwise, and fore-stock 16 is elongated by 23 extension springs 24 of chain, makes extension spring 24 be in tension state (shown in Fig. 5).Once open seat machine frame, button press 32 again, when alignment pin 18 is ejected folding lock-bit groove 22, now under the effect of extension spring 24 pulling force, seat machine frame just automatically opens up, alignment pin 18 can find quickly, neatly and stretch the position that lock-bit groove 21 aligns, and alignment pin 18 is stretched lock-bit groove 21 by stage clip 17 jacking again, makes frame be in and opens lock-out state.
In sum, the present invention compared with prior art, has the advantages that
1, fold, launch conveniently.
2, rapid operation, has greatly facilitated user and has used wheelchair.
3, location is stretched quickly, flexibly.
4, folding volume is little, brings convenience to the vanning of wheelchair so that it is very easily load automobile trunk.
