Description

Skeleton structure of baby carriage

technical field

The utility model relates to a skeleton structure of a stroller.

Background technique

Generally, a stroller for carrying a baby is usually in the shape of a connecting rod with the rods pivoted to each other, and a joint group arranged between the rods is controlled by a release mechanism, and the lock mechanism in the joint group is released and locked. The buckle has an expanded use position that can be carried and a baby can be carried and a folded position that can be folded and placed, such as U.S.PAT. The rod combination is quite complicated, not only is it quite difficult to assemble and the procedure is very complicated, but also because there are quite a lot of rods, the weight of the overall skeleton is relatively increased, and the user is more cumbersome when moving, and The effect of interlocking movement during folding is not good, and it is easy to cause the problem that the skeleton is not smooth when folding.

Contents of the invention

Therefore, in order to solve the problem that the above-mentioned known stroller skeleton structure has complicated components and the skeleton is not folded smoothly, the utility model provides a skeleton structure of the stroller, which at least includes: a front wheel bracket, which is connected to The front wheel of the stroller; a rear wheel bracket connected to the rear wheel of the stroller; a handle tube; a frame including a front seat post and a rear seat post pivotally connected to each other, and the seat frame is respectively pivotally connected to the front wheels Bracket and rear wheel bracket; it is characterized in that a fastening seat is provided between the two ends of the rear wheel bracket; a connecting assembly is pivotally connected between the two ends of the handle tube, and the connecting assembly can be used as the two ends of the stroller. The armrest supported by the side, and the other end of the connection component is pivotally connected with the front wheel bracket and the rear wheel bracket, and one end of the handle pipe is buckled with the buckle seat in a releasable manner; and a linkage Two ends of which are respectively pivotally connected between the handle pipe and the rear wheel bracket; a driving part is slidably installed on the rear seat post, and the driving part is connected with the linkage. And the driving part is driven and slid by the linking part when the frame is folded, so that the rear seat post is pressed by the driving part so that the seat frame is folded, and then drives the front wheel bracket and the rear wheel The bracket moves closer or unfolds towards the middle, so that the utility model can achieve a relatively smooth folding effect.

Other purposes and further applicable scope of the present utility model can be clearly understood from the following detailed description. However, these detailed descriptions and mentioned embodiments are only for illustration, because various changes and modifications made in the spirit and scope of the present utility model are sufficient for professionals in this industry. It is clearly known from these detailed descriptions and drawings, but these detailed descriptions and drawings are for illustration purposes only, and should not limit the utility model.

Detailed ways

For the technical content disclosed in the utility model, please refer to Fig. 1 and Fig. 2. The skeleton 90 structure of the stroller of the utility model is mainly composed of a front wheel bracket 1, a rear wheel bracket 2, and a linkage 3. , buckle seat 4, a handle pipe 5, seat frame 6, connecting assembly 7 and driver 8 are pivotally connected to each other, and it has an unfolded state, as shown in Figure 1, and a folded state, as shown in Figure 1 4.

Wherein the front wheel bracket 1, its lower end is connected with the front wheel 10 of the stroller, and its upper end is pivotally connected with the connecting assembly 7. The rear wheel support 2 is connected to the rear wheel 20 of the stroller at its lower end, and is pivotally connected with the connecting assembly 7 at the upper end. In addition, a buckle seat 4 is arranged between its two ends, and the buckle seat 4 is connected with the handle The buckling of the tube 5 keeps the frame 90 in the unfolded state.

The handle pipe 5 is used to push the stroller, and a connecting assembly 7 is pivotally connected between the two ends as the armrest of the stroller. The other end of the connecting assembly 7 is pivotally connected to the front wheel bracket 1 and the rear wheel bracket 2 respectively. ; In addition, the lower end of the handle pipe 5 is equipped with a catch piece 51, which is buckled with the buckle seat in a releasable manner by the catch piece 51, so as to generate or release a lock that occurs in the rear wheel bracket 2, The interlocking state between the connecting component 7 and the handle tube 5: in this embodiment, the locking member 51 mainly uses a release mechanism 52 to control the movement of the locking member 51, and the releasing mechanism 52 can Such as Taiwan Patent Publication No. 515423 or US Patent No. 6443479.

One end of the linkage 3 is pivotally connected to the lower end of the handle pipe 5, and the other end is pivotally connected to the middle section of the rear wheel bracket 2. The seat frame 6 includes a front seat post 61 and a rear seat post 62 that are pivotally connected to each other, wherein the front seat post 61 is pivotally connected to the front wheel support 1, and the rear seat post 62 is pivotally connected to the rear wheel support 62, by The unfolding and folding of the seat frame 6 further drives the unfolding and folding of the front wheel bracket 1 and the rear wheel bracket 2 . The driving part 8 is slidably installed on the seatpost 62 behind the seat frame 6, and the driving part 8 is connected with the linking part 3, so that the driving part 8 can be driven by the rotation of the linking part 3 to move .

With the above-mentioned components, when the framework 90 is unfolded, it is mainly fixed by the locking part 51 at the lower end of the handle pipe 5 and the buckle seat 4 fixed on the rear wheel bracket 2, so that each rod can form a It is deadlocked and unable to rotate, so as to provide the use of carrying infants and children; and when the skeleton is to be folded, the latch 51 is released, the operation pushes the handle tube 5 forward, and the linkage 3 is driven by the handle tube 5 The rotation, and because the drive member 8 is pivotally connected with the linkage member 3 . Therefore, when the linking part 3 rotates, it can drive the driving part 8 to move at the same time, and then the rear seat frame 62 and the front seat post 61 are folded in an inverted "V" shape, so that the folding of the seat frame 6 can Make the front wheel bracket 1 and the rear wheel bracket 2 close to each other, and then achieve the purpose of folding the baby carriage frame.
