Detailed description of the invention

It is referred to accompanying drawing Fig. 1～Figure 14 below and word content understands present disclosure And the distinctive points between the present invention and prior art.Hereafter by accompanying drawing and enumerate the present invention The mode of some alternative embodiments, to technical scheme (including optimal technical scheme) It is described in further detail.It should be understood that any technical characteristic in the present embodiment, Any technical scheme be all the one in the technical characteristic of plurality of optional or optional technical scheme or Several, in order to describe succinct need in presents cannot the exhaustive present invention all alternatively Technical characteristic and alternative technical scheme, be also not easy to the embodiment of each technical characteristic All emphasize that it is one of optional numerous embodiments, so those skilled in the art should know: Any two arbitrary technological means that the present invention provides can being replaced or the present invention being provided Individual or more technological means or technical characteristic are combined mutually and obtain new technical scheme. Any technical characteristic in the present embodiment and any technical scheme are all not intended to the protection of the present invention Scope, protection scope of the present invention should include that those skilled in the art do not pay creative work Thinkable any alternate embodiments and those skilled in the art appointing that the present invention is provided The new technology that two or more technological means of anticipating or technical characteristic are combined mutually and obtain Scheme.

Embodiments provide a kind of simple in construction, it is simple to fold, be difficult to the baby of tong Vehicle carriage.

The technical scheme provided the present invention below in conjunction with Fig. 1～Figure 14 is carried out in more detail Illustrate.

As shown in Fig. 1～Figure 14, the stroller frame that the embodiment of the present invention is provided, including One support body the 1, second support body 2 and support member 3, wherein:

Rotating junction 31 and slide contact part 32 it is provided with on support member 3.

First support body 1 is flexibly connected with the second support body 2, the first support body 1 and the second support body 2 liang One of them rotating junction 31 with support member 3 of person is rotatably connected, the first support body 1 and Both two support bodys 2 wherein another slide contact part 32 with support member 3 is slidably connected.

First support body 1 relative to the second support body 2 when stowed position moves to expanded position, One support body 1 and the second support body 2 can drive support member 3, make the rotating junction 31 of support member 3 Turn to expanded position around pivot center from stowed position, make the slide contact part 32 of support member 3 Expansion is slid into along the glide direction preset from stowed position in the width range of stroller frame Position.The width that glide direction is described stroller frame preset (can be managed in Fig. 3 Solve as left and right directions) or be the width of described stroller frame and described stroller frame Direction (default glide direction does not include length direction) between length direction；

First support body 1 relative to the second support body 2 when expanded position moves to stowed position, One support body 1 and the second support body 2 can drive support member 3, make the rotating junction 31 of support member 3 Turn to stowed position around pivot center from expanded position, make the slide contact part 32 of support member 3 In the width range of stroller frame, the opposite direction along the glide direction preset is sliding from expanded position Move to stowed position.

In the stroller frame that the embodiment of the present invention provides support member 3 adjusted to expanded position can To realize support to first support body the 1, second support body 2, support member 3 and the first support body 1, the The mode being connected by being slidably connected with being rotationally connected between two support bodys 2 is connected, and connects knot Structure is simple, compact, and support member 3 can link in company with first support body the 1, second support body 2, it is not necessary to Individually apply external force and drive support member 3, more convenient folding, additionally, support member 3 in the present invention Slide contact part 32 can in the width range of stroller frame along preset glide direction (width of such as stroller frame) slides into stowed position from expanded position, fully profit With the idle space in stroller frame width range, the limit on stroller frame width Along position (between the most left pulling handle rod and left underframe bar and right pulling handle rod and right underframe bar it Between) it is difficult to that tong gap occurs, occur that the probability of tong phenomenon is relatively low, make folding further more For convenience, safety is more preferable.

As the further optimization of the arbitrary technical scheme of the present invention, stroller frame also includes arranging Between support member 3 and the first support body 1 or be arranged between support member 3 and the second support body 2 Latch-up structure 4, wherein:

First support body 1, was locked relative to the second support body 2 when stowed position moves to expanded position Support member 3 can be locked on the first support body 1 and/or the second support body 2 by fixed structure 4.Release (lock Fixed structure 4 is to support member 3) locking, the first support body 1 can be relative to the second support body 2 from exhibition Open position is moved to stowed position.

The stroller frame that latch-up structure 4 can make the present invention provide is reliable, be firmly in exhibition Open state, and then be used for putting into baby and article.

As the further optimization of the arbitrary technical scheme of the present invention, latch-up structure 4 includes draw-in groove 41, spring element 42, hook 43 and unblock driving means 44, wherein:
