Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, two road lock systems of doll carriage of the present invention and doll carriage are further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Referring to figs. 1 through Figure 11, doll carriage one embodiment of the present invention comprises the vehicle frame with expanded position and folding position, be arranged on the front component 1 of front portion at the bottom of vehicle frame, be arranged on the wheel assembly 9 at rear portion at the bottom of vehicle frame, vehicle frame comprises bracing frame 10 at the bottom of front-wheel support 3, rear wheel support 6, push rod (not shown), mounting pipe 11, X-shaped, folding rear support assembly 8 and folding backrest module 4, front-wheel seat 2 on front component is connected with front-wheel support 3, and the rear wheel seat 7 on wheel assembly 9 is connected with rear wheel support 6.
Push rod is connected by joint pivotable with front-wheel support 3, mounting pipe 11 is set between front-wheel support 3 and rear wheel support 6, mounting pipe 11 connects front-wheel support 3 and rear wheel support 6 respectively, mounting pipe 11 is provided with backrest module 4, backrest module 4 is connected with two mounting pipes 11 with the second back support bar 42 respectively by the first back support bar 41.
Two road lock systems 5 are arranged on vehicle frame, two road lock systems 5 comprise the first connecting panel 51, second connecting panel 52 and elastic component, the first end (the first pivoted hole 511 place) of the first connecting panel 51 is articulated in first side (left side) of described vehicle frame, is articulated in the first back support bar 41; Second end (the second pivoted hole 514 place) of the first connecting panel 51 is connected by pivot 55 pivotable with second end (the 3rd pivoted hole 521 place) of the second connecting panel 52, the first end (the 4th pivoted hole 523 place) of the second connecting panel 52 is articulated in second side (right side) of described vehicle frame, is articulated in the second back support bar 42; First connecting panel 51 and the second connecting panel 52 are made up of plastics or metallic material, preferred rigidity band iron.
The shape of the first connecting panel 51 is dihedral, and the end being provided with the second end of the second pivoted hole 514, first connecting panel 51 near the dihedral bending part of the first connecting panel 51 arranges lug boss 512; Wherein, the angle of the first connecting panel 51 bending part is 165 ° ± 10 °, preferably 170 °; The ratio that first connecting panel 51 is bent into two segment length of dihedral is 2.5 ~ 3.0.Circumference is provided with the cylinder of circular groove to lug boss 512 or cross section is T-shaped cylinder, the line of centers of lug boss 512 and the centerline parallel of pivot 55.
One end of elastic component is fixed on the first connecting panel 51 or the second connecting panel 52, and the other end is arranged on described vehicle frame, and preferably, the other end of elastic component is connected in the first back support bar 41 or in the second back support bar 42;
When vehicle frame is in described expanded position, lug boss 512 stops that the second connecting panel 52, first connecting panel 51 and the second connecting panel 52 are locked;
When vehicle frame is in described folding position, the first connecting panel 51 and the second connecting panel 52 are folded into X-shaped.
Two road lock systems 5 also comprise unblock pedal 53, unlock pedal 53 to be made up of plastics or rubber, unlock pedal 53 be arranged on the end of the first end (right-hand member) of the second connecting panel 52 and extend to outside vehicle frame, when unlocking pedal 52 and declining by external force F, lug boss 512 no longer contacts with the second connecting panel 52, and the first connecting panel 51 and the second connecting panel 52 unlock.
More preferably, as a kind of embodiment, elastic component is extension spring or torsion spring, elastic component is two, be respectively the first elastic component 56 and the second elastic component 54, one end of first elastic component 56 connects the first connecting panel 51 by the first spring eye 513, and the other end connects the first back support bar 41 in backrest module 4; One end of second elastic component 54 connects the second connecting panel 52 by the second spring eye 522, and the other end connects the second back support bar 42 in backrest module 4.The stress balance being arranged so that two road lock systems of two elastic components.
More preferably, as a kind of embodiment, the articulated section (the first pivoted hole 511) of the first end (left end) of the first connecting panel 51 is identical to the distance of pivot 55 with the articulated section (the 4th pivoted hole 523) of the first end of the second connecting panel 52 to the distance of pivot 55.Namely the distance of the first pivoted hole 511 to the second pivoted hole 514 is identical with the distance of the 3rd pivoted hole 521 to the four pivoted hole 522, and wherein the second pivoted hole 514 and the 3rd pivoted hole 521 are for running through pivot 55.Pivot 55 is arranged at the middle part of vehicle frame, synchronous with vehicle frame folding during two road lock systems fold, convenient folding.
The first connecting panel 51 in two road lock systems 5 and the second connecting panel 52 are rigidity band iron, when baby gravity G is applied on seat, front-wheel support 3, rear wheel support 6 there will be to frame inside depression trend by the effect of gravity G, owing to having the support of rear support assembly 8, the distance between two rear wheel supports 6 can not change, simultaneously, the front end of mounting pipe 11 also there will be to frame inside depression trend, as shown in figure 12, joint in the middle part of front-wheel support 3 there will be the trend caved in along the direction of arrow in figure to dotted portion, namely the front-wheel support 3 meeting slope trend to the right on the left of doll carriage, front-wheel support 3 on the right side of doll carriage can be tilted to the left trend, but owing to being provided with two road lock systems 5, two road lock systems 5 will support the first back support bar 41 when locking, second back support bar 42 and mounting pipe 11 do not cave in frame inside, thus ensure that the distance between two front-wheel supports 3 there will not be significant change, even if it is also slight change that the distance between two mounting pipes 11 changes, front-wheel support 3 and mounting pipe 11 can not be made to frame inside depression too much, thus actv. solves the problem caved in toward frame inside in front-wheel support 3 center knuckle place, wider space is had when allowing baby be sitting in seat, overcome seat space to diminish, the hand activities space of baby is little, the problem of limitation of activity.
The nouns of locality such as front, rear, left and right involved above define under stroller frame is in expanded position, and the position at front component place is anterior, and the position at wheel assembly place is rear portion.
Doll carriage in above-described embodiment, its two road lock system architecture is simple, easy to operate, only can need be folded by Xia Cai bis-road lock pedal; Fixing vehicle frame can be realized without the need to operating two road lock systems when vehicle frame launches.The doll carriage applying two road lock systems has higher reliability and safety, causes unlocking the safety misadventure caused when avoiding implementation because of the maloperation to lockout mechanism; Meanwhile, two roads lock systems are set at baby carriage back rest assembly, efficiently solve the problem that front-wheel support center knuckle place and mounting pipe cave in frame inside, ensure that infant seat has wider space.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
