The specific embodiment

Below, by reference to the accompanying drawings and the specific embodiment, the present invention is described further:

As shown in Figure 1,2,3, 4, for a kind of new type foldable of the present invention mechanism, it comprises vehicle frame 10, support beam 20, two driven units and transmission component, wherein, vehicle frame 10 includes two side plates 11 of arranging and being oppositely arranged at its Width, between biside plate 11, form an accommodation space, this biside plate 11 has formed the base portion of vehicle frame 10, between the top ends of biside plate 11, be fixedly connected with, accommodation space at least has the fluting that miscellaneous part can be snapped in rear side and the bottom of biside plate 11.The upper end of support beam 20 is articulated on vehicle frame 10 by a pivot 21 extending along vehicle frame 10 Widths, concrete is, this pivot 21 is arranged between the rear side top ends of biside plate 11, support beam 20 can around pivot 21 one the collapsed position in accommodation space and between the expanded position of accommodation space outside, rotate, that is to say, at folded bicycle during in folding state, support beam 20 turns to vertical state around pivot 21, it is finally placed in accommodation space, now, the biside plate 11 of vehicle frame 10 can not interfere with support beam 20, that is to say, distance between biside plate 11 is greater than the width of support beam 20, at folded bicycle during in deployed condition, support beam 20 turns to vertical state and is an angle around pivot 21, it is positioned at beyond accommodation space, the bottom of support beam 20 is provided with wheel 30.Two above-mentioned driven units are placed in respectively on biside plate 11, this driven unit comprises that one is articulated in external toothing 41 on side plate 11, be articulated in the driven gear 44 meshing with external toothing 41 on side plate 11, synchronously be connected in the drive sprocket 45 on driven gear 44, be articulated in the driven sprocket 47 on pivot 21, and by drive sprocket 45 and the synchronous driving chain 46 connecting of driven sprocket 47, the periphery of external toothing 41 is articulated with stretcher 43, stretcher 43 on two driven units mutually staggers on the circumferencial direction of the pivot center of external toothing 41, when trampling two stretchers 43, two driven units can be synchronous rotation, finally make two driven sprockets 47 synchronously rotate.For the ease of installing, can on side plate 11, offer a circular open 111, in this opening 111, be fixed with a lasso 13, on external toothing 41, having one is embedded in lasso 13 and the portion that sets that can rotate with respect to lasso 13, that is to say, lasso 13 and the portion of setting form a structure that is similar to bearing, lasso 13 is for being regarded as the outer ring of bearing, the portion of setting is regarded as the inner ring of bearing, this structure is external toothing 41 to be articulated in to opening 111 inside of side plate 11, set and in portion, be fixed with a swivel becket 42, the periphery of this swivel becket 42 has an extension extending radially outwardly 421, stretcher 43 is articulated in the outboard end of extension 421, extension 421 can increase the moment that stretcher 43 makes external toothing 41 rotate when pressurized, at the medial surface of side plate 11, this is fixed with an adapter plate 12, driving chain 46, drive sprocket 45, driven gear 44 and driven sprocket 47 are all placed between adapter plate 12 and side plate 11, thereby avoid support beam 20 after being folded among accommodation space, interfere with driving chain 46, drive sprocket 45, driven gear 44 and driven sprocket 47.

In the present invention, above-mentioned external toothing 41 and driven gear 44 engagements, simultaneously, driven gear 44 is by chain drive outputting power and pass to transmission component, is rotated, so by transmission component band motor car wheel 30, can, when trampling two stretchers 43, wheel 30 be rotated.Yet, as long as the power of stretcher 43 can be passed to transmission component via driven unit, therefore, in the present invention, can adopt other the rotatable parts that are articulated on side plate 11 to substitute above-mentioned external toothing 41, adopt other another rotatable parts that are articulated on pivot 21 to substitute above-mentioned driven sprocket 47, between these two rotatable parts, can adopt gear cluster synchronously to connect, can be also to adopt other synchronous draw bail to coordinate.

Above-mentioned transmission component comprises the drive link 51 that is built in support beam 20 and extends along the short transverse of support beam 20, be articulated in and on pivot 21 and with driven sprocket 47, synchronize the transmission shaft 52 connecting, synchronously be connected in the first bevel gear 53 on transmission shaft 52, the second bevel gear 54 that is synchronously connected in drive link 51 upper ends and meshes with the first bevel gear 53, synchronously be connected in the 3rd bevel gear 55 of drive link 51 bottoms, and be synchronously connected on the wheel shaft 31 of wheel 30 and with the 4th bevel gear 56 of the 3rd bevel gear 55 engagements, transmission shaft 52 cross-under are in pivot 21, its the two central axes, two above-mentioned driven sprockets 47 respectively key are connected in the both ends of transmission shaft 52, because two driven sprockets 47 are synchronous rotations, therefore, in the situation that two driven sprockets 47 rotate, its the two common transmission shaft 52 that drives rotates, the rotational power of transmission shaft 52 passes to drive link 51 by the first bevel gear 53 and coordinating of the second bevel gear 54, the rotational power of drive link 51 passes to the wheel shaft 31 of wheel 30 by the cooperation of the 3rd bevel gear 55 and the 4th bevel gear 56, finally make wheel 30 rotate.

In the present invention, owing to adopting driven unit on vehicle frame 10, at the built-in installation transmission component of support beam 20, because support beam 20 is to rotate with respect to vehicle frame 10 around pivot 21, and the power of driven unit output end (being driven sprocket 47) is on the transmission shaft 52 on pivot 21 with transmission component cohesive position just, therefore, in the process of folding folded bicycle, can there is not any interference with driven unit and transmission component in support beam 20, the driving device of folded bicycle can not be affected, this is in conjunction with coordinating two driven units to be arranged at respectively the ingenious structure on biside plate 11, make support beam 20 just can be placed between biside plate 11 when folding state, thereby utilized the inner space of vehicle frame 10, dwindled the volume of folded bicycle folding state, simultaneously, as above-mentioned, describe, due to the central axes of pivot 21 with transmission shaft 52, at support beam 20 during in folding state, wheel 30 can normal rotation, folded bicycle can normally be ridden even.

To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the claims in the present invention.
