Summary of the invention
The utility model is exactly the deficiency that exists in the prior art for solving, and a kind of bicycle folding sunshade that is fixed on the car after poppet is provided.
The technical solution of the utility model is: be connected by Double pin hinge between the middle upper ledge of sunshade and the middle lower frame, be connected by flexible hinge between middle lower frame and the lower frame and between upper ledge and the middle upper ledge; Be provided with in the intersection of upper ledge and last montant and turn to hinge and hinge spring; In the intersection of two bars and middle montant also be provided with and turn to hinge and cut with scissors spring; Between sheer pole and following pair bar,, also be provided with between cross tube and the last montant and turn to hinge and hinge spring through turning to hinge to be connected with the retractable support connecting rod.
The further technical solution of the utility model is:
The cross-under on one side of the frame linking of said flexible hinge is in the blank pipe of a side, and the another side cross-under is in elongated slot.
Said Double pin hinge be two near blank pipe, middle upper ledge and middle lower frame and in the termination of two bars insert in the blank pipe.
The said blank pipe of hinge one side and the blank pipe of opposite side of turning to is 90 ° mutually.
Sunshade is connected with connection-peg through shank, and the bracing frame and the car body back rest of the four-bar linkage that is made up of frame, arc frame, connecting rod, strut are fixed, and outside whole sunshade, are coated with one deck canopy cloth.
Can find out through above technical scheme owing to have novel structure design, make this sunshade at the hinge spring, turn to the combined action of hinge, flexible hinge, Double pin hinge can freely fold perhaps down to strut.Can block strong exposure in sunshine or rainwater drenches for rider after strutting, volume after folding is less, conveniently deposits.Main is good stability, can guarantee the traffic safety of rider.The utility model is fit to vehicle to be used in leisure or slow low speed driving.

Fig. 1 is the integral structure scheme drawing of the utility model.
Fig. 2 is the local structure for amplifying scheme drawing in the A place of Fig. 1.
Fig. 3 is the structural representation of folding support stand.
Fig. 4 is sunshade and folding support stand bonded assembly structural representation.
The specific embodiment
As shown in Figure 1, the utility model mainly is by upper ledge 4, middle upper ledge 3, middle lower frame 1, lower frame 13, Double pin hinge 2, flexible hinge 8, turns to hinge 9 and 10, cross tube 14, middle cross bar 15, sheer pole 16 and several to constitute with the hinge spring that turns to hinge 9,10 to cooperate 5,7.Wherein, Be equipped with flexible hinge 8 (referring to Fig. 2) between upper ledge 4 and the middle upper ledge 3 and between middle lower frame 1 and the lower frame 13; And be provided with Double pin hinge 2 between middle upper ledge 3 and the middle lower frame 1; All insert in the Double pin hinge 2 with the termination of middle lower frame 1 with an end and the middle upper ledge 3 of two bars 20 in middle montant 18 pivotallys attached, also insert in the Double pin hinge 2 termination of following pair bar 17 and lower frame 13.Last montant 6 with between two bars 21, between montant 6 and the cross tube 14, in be connected by turning to hinge 9,10 and cutting with scissors spring 5,7 between two bars 20 and the middle montant 18, to realize being mutually 90 ° amount to.Middle montant 18 extends shank 12.Between sheer pole 19 and middle montant 18, be provided with retractable support connecting rod 11.Said each be coated with one deck above the parts and constitute a whole sunshade by the canopy cloth 16 of rainproof material.
Referring to Fig. 2; Said flexible hinge 8 is made up of two parts; Flexibly connect through a square or rectangular frame linking 22 between two parts; The top of frame linking 22 is through in the blank pipe of flexible hinge 8, and the bottom of frame linking 22 is through in the elongated slot 23 of flexible hinge 8 and can up-and-down movement, with the function that realizes stretching.All insert in the blank pipe of flexible hinge 8 termination of upper ledge 4, middle upper ledge 3 and upward two bars 21, and can rotate.
Fig. 3 has shown the structure that supports the folding support stand of sunshade.On the back rest 24 perhaps electronic with battery-driven car, bicycle, that manpower driving leisure bicycle is fixing, be connected with frame 31; One end of frame 31 is connected with the shaft pertaining of arc frame 30; The two ends of connecting rod 29 are connected with 25 of back rest 24 and struts respectively; The centre of connecting rod 29 is connected with 30 of arc frames again, all component set-up one folding support stand.In arc frame 30, designed the chute 27 of arc, the axle 28 of strut 25 is positioned at chute 27 and slides, and is provided with a maintenance filler ring 26 in another termination of arc frame 30.The termination of strut 25 is connected with fulcrum 32.
Because the relation of four-bar linkage, the axle 28 in the folding support stand on the strut 25 can slide front and back in the chute 27 of arc frame 30.When axle 28 gets into the recess of maintenance filler ring 26 bottoms, will be held, realize the location, the fulcrum 32 of this moment is in the extreme higher position.Lift the recess that strut 25 makes axle 28 break away from maintenance filler ring 26 bottoms during gathering, just can realize along chute 27 impeller-hubs 28 again.
