The embodiment provides a foldable baby carriage frame, when the baby carriage frame is unfolded, a seat matched with the baby carriage frame can be assembled to form a baby carriage for children to sit, and after the baby carriage frame is folded, the occupied space can be reduced, and the baby carriage frame is suitable for being stored.

Referring to fig. 1, the frame of the stroller comprises a base 1, a front wheel rod 2, a rear wheel rod 3, a push rod 4, a seat rod 5 and a folding mechanism 6. The front wheel rod 2, the rear wheel rod 3 and the push rod 4 are all pivoted on the base body 1, wherein the front wheel rod 2 and the rear wheel rod 3 are respectively positioned at the front side and the rear side of the frame of the baby carriage and are respectively used for installing the front wheel 21 and the rear wheel 31 of the baby carriage, and the push rod 4 extends towards the rear side of the frame of the baby carriage so as to be suitable for parents to support and push the frame of the baby carriage to advance. The front wheel rod 2, the rear wheel rod 3 and the push rod 4 are preferably coaxially pivoted to the base body 1 so as to be capable of rotating around the base body 1 when the stroller frame is folded or unfolded, so that the base body 1 is formed as a folding center of the stroller frame and is allowed to be substantially formed into a shaft-like structure with small volume. The seat post 5 is movably connected to the base 1, and can be provided with a slot and other structures for assembling a seat.

The folding mechanism 6 is in transmission connection with the front wheel rod 2, the rear wheel rod 3, the push rod 4 and the seat rod 5, so that when the folding mechanism is driven by external force, the front wheel rod 2, the rear wheel rod 3, the push rod 4 and the seat rod 5 can be pulled in a linkage manner, the front wheel rod 2, the rear wheel rod 3, the push rod 4 and the seat rod 5 can move simultaneously and gather to a folding position in opposite directions, or the front wheel rod 2, the rear wheel rod 3, the push rod 4 and the seat rod 5 can move reversely to an unfolding position simultaneously, so that the folding state and the unfolding state of the baby carriage frame are corresponding.

Typically, the external forces for collapsing the frame of the stroller are derived from the pushing/pulling force exerted by the household upon the push rod 4 or other component in driving connection with the collapsing mechanism 6. In order to replace the parent to apply the external force to avoid the trouble of manually folding the frame of the stroller, the frame of the stroller further comprises at least one elastic member 7, the elastic member 7 is disposed between the base 1 and the seat rod 5, and when the seat rod 5 is in the unfolded position, the elastic member 7 can generate elastic deformation so that the seat rod 5 has a movement tendency toward the folded position. That is, when the frame of the stroller is in the unfolded state, the elastic member 7 can be elastically deformed to obtain elastic potential energy, and when the unfolded state of the frame of the stroller is released, the elastic member 7 can be restored to be deformed, so that the external force is applied to the folding mechanism 6 by the seat rod 5, and the folding mechanism 6 is driven to pull the front wheel rod 2, the rear wheel rod 3 and the push rod 4 to move, so that the frame of the stroller is switched to the folded state.

Illustratively, the folding mechanism 6 includes a first link 61, a second link 62 and a third link 63 pivotally connected in series, wherein an end of the first link 61 facing away from the second link 62 is pivotally connected to the first pivot 10 on the front wheel bar 2, a middle section of the second link 62 is pivotally connected to the second pivot 20 on the rear wheel bar 3 and the third pivot 30 on the seat bar 5, respectively, and the third link 63 is pivotally connected to the fourth pivot 40 on the push rod 4.

As shown in fig. 1 to 4, in this embodiment, the pivot joint of the rear wheel lever 3 and the second link 62 is located at one side of the pivot joint of the seat lever 5 and the second link 62, which is close to the first link 61. When the elastic member 7 applies an external force to the seat post 5, the seat post 5 will move to the lower right in fig. 1 and be pulled by the seat post 5, the second link 62 will be driven by the seat post 5 to rotate clockwise around the second pivot 20 from the state shown in fig. 1, so as to pull the front wheel post 2 and the rear wheel post 3 to rotate around the base 1 in opposite directions, and at the same time, pull the push rod 4 and the rear wheel post 3 to rotate in opposite directions, and according to the folding process of the stroller frame, the stroller frame will take the states shown in fig. 2 and 3 in sequence and finally take the folding state shown in fig. 4.

Illustratively, the elastic element 7 is a tension spring, one end of which is hooked to the first mounting rod 11 fixedly disposed on the base 1, and the other end of which is hooked to the second mounting rod 51 fixedly disposed at one end of the seat post 5 departing from the second link 62. When the stroller frame is in the unfolded state of fig. 1, the tension spring is pulled and stretched by the second mounting rod 51, causing elastic deformation as described above. When the tension spring is deformed again, the tension spring pulls the second mounting lever 51 in the reverse direction, thereby moving the seat lever 5 to the lower right in fig. 1. Preferably, the base body 1 is formed with a sliding sleeve 12, and the seat post 5 is slidably connected to the sliding sleeve 12 and can slide relative to the sliding sleeve 12 to obtain a stable linear moving path, so as to effectively pull the second connecting rod 62 to move according to the stable path.

Alternatively, the elastic element 7 may be a compression spring, one end of which is connected to the base body 1, and the other end of which is connected to the end of the seat lever 5 close to the second link 62, so as to achieve the same traction effect as the above-mentioned compression spring.

It will be understood that in order to keep the stroller frame in the unfolded position, the stroller frame should be provided with a locking mechanism (not shown) which keeps the tension spring in a stretched state, i.e. the seat post 5 in the unfolded position described above, against the elastic force of the elastic member 7 returning to its deformation.

As shown in fig. 1 and 5, in the present embodiment, the push rod 4, the rear wheel bar 3, the portion of the second link 62 between the second pivot 20 and the third link 63, and the fourth link 63 form a four-bar linkage mechanism, and when there is no foreign object stop between the four links, any two of the four links can rotate relatively to each other, so as to unfold or fold the stroller frame. After the second link 62 and the third link 63 are locked, the second link 62 and the third link 63 cannot rotate relatively to be regarded as a whole, and at this time, the four links form a stable triangular structure.

Based on this, the lock mechanism is used to lock the first link 61 and the second link 62 when the stroller frame is in the unfolded state, so that the push rod 4, the rear wheel lever 3, the second link 62, and the third link 63 are locked. In association, since the second link 62 is locked, the front wheel lever 2, the rear wheel lever 3, the first link 61, and the portion of the second link 62 interposed between the first link 61 and the second pivot 20 will also constitute a stable triangular mechanism, so that the front wheel lever 2 is locked. Furthermore, the seat post 5, constrained by the second link 62 and the base 1, will also be locked together, thus keeping the entire stroller frame in a stable unfolded state, ensuring the safety of the stroller in parking and pushing forward.

In this embodiment, when the seat lever 5 is switched from the unfolded position to the folded position, the locking mechanism can be switched from the unlocked state to the locked state. The locking mechanism may be an elastic locking pin, a quick buckle, a wedge-shaped locking sleeve, etc. commonly used in infant carriers, and the structure of the locking mechanism is not shown in the drawings, and is not an improvement point of the present application, and therefore, detailed description and limitation are not given here.

In other embodiments, the pivot joint of the rear wheel lever 3 and the second link 62 can also be arranged to be located on one side of the pivot joint of the seat lever 5 and the second link 62 near the third link 63. At this time, the seat rod 5 can drive the second connecting rod 62 in a manner opposite to the unfolding and folding actions in this embodiment, and accordingly, the elastic element 7 also drives the seat rod 5 to move in an opposite force application direction, which is not described herein again.

In addition, in order to further fold the frame of the stroller, the portion of the push rod 4 above the fourth pivot 40 can be configured to be able to be retracted, and the supporting plate 8, the grab bar 9, etc. connected to the seat bar 5 for supporting the legs of the child can also be configured to be rotatable, foldable, retractable, etc. these structures can be implemented according to similar prior art, and will not be described herein again.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, adaptations and substitutions will occur to those skilled in the art without departing from the scope of the utility model. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
