Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clear, complete description, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work The every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig.1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.A kind of bicycle with Multifunctional real seat, structure include: a vehicle list First 2, one hollow stem 3, an inner shaft 4, a back seat 5 and a rotation axis 6.

The vehicle unit 2 includes fixing piece 23 after fixing piece 22 and one before a cushion 21, one.

The hollow stem 3 includes a built-in space 31 and two shrinkage pools 32.The bottom of the hollow stem 3 be connected to it is described after On fixing piece 23.

The inner shaft 4 is located at the built-in space 31 of the hollow stem 3, is equipped with a flexible fastening piece in the inner shaft 4 41.The top of the inner shaft 4 is connected to the back seat 5.

The back seat 5 includes a pedestal 51, a supporting element 52 and a hinge connector 53, and the pedestal 51 is equipped with two Groove 511, a groove 512 and a fixing piece 513, the hinge connector 53 are located in groove 512,52 liang of the supporting element Side is respectively provided with a shrinkage pool 521 and a convex block 522, and one end of the convex block 522 is located on groove 511, the hinge connector 53 one end connect the rotation axis 6, and the other end of hinge connector 53 connects the side of the pedestal 51, and the supporting element 52 connects It connects in the bottom end of pedestal 51.

The side of back seat 5 described in one end Jie of the rotation axis 6, it is solid before the other end connection of the rotation axis 6 is described Determine part 22.

Referring to Fig.1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.When the inner shaft 4 is displaced to the another of hollow stem 3 from built-in space 31 When end, the inner shaft 4 elongates the other end for arriving hollow stem 3, it will promotes the flexible fastening piece 41 to pop up, is stuck in hollow stem It is fixed at two shrinkage pools 32 of 3 other ends.At this point, the back seat 5 will be that one first rotation fortune is made in axle center with the rotation axis 6 Dynamic 71, make back seat 5 and cushion 21 at an angle 73, provides the back seat 5 at a support body back for rider.

When to release the fixation of the hollow stem 3 and inner shaft 4, user must press inward against flexible fastening piece 41 simultaneously The inner shaft 4, which is pressed down, to be made the flexible fastening piece 41 leave two shrinkage pools, 32 position and no longer fixes, then, the inside Bar 4 will move on to one end of the hollow stem 3 from the other end of the hollow stem 3.At this point, the back seat 5 will be with the rotation axis 6 Make one second rotary motion 72 for axle center, back seat 5 and cushion 21 is made substantially in parastate, one can be carried on the back seat 5 Object or a passenger.
