Detailed Description

As shown in fig. 1 to 6, the stroller frame a of the present invention can be converted between an unfolded state and a folded state, the stroller frame a includes a front leg 1, a rear leg 2, a first connecting member 3, and a second connecting member 4, the first connecting member 3 is pivoted to the rear leg 2 in a crossed manner, a rear side of the front leg 1 is pivoted to the first connecting member 3, one side of the second connecting member 4 is pivoted to the front leg 1, the other side is pivoted to the rear leg 2, and the front leg 1, the rear leg 2, the first connecting member 3, and the second connecting member 4 form a four-bar linkage structure.

In the present embodiment, the front side of the second connecting element 4 is pivoted to the front leg 1, and the rear side is pivoted to the front side of the rear leg 2. Preferably, the front lower side of the second connecting element 4 is pivotally connected to the front leg 1, and the rear upper side is pivotally connected to the front side of the rear leg 2.

The first connecting piece 3 is pivoted with the rear leg 2 through a first rotating shaft 31, the rear side of the front leg 1 is pivoted with the first connecting piece 3 through a second rotating shaft 11, and the second connecting piece 4 is pivoted with the rear leg 2 through a third rotating shaft 41 and pivoted with the front leg 1 through a fourth rotating shaft 42.

When the stroller frame a is in the unfolded state, the fourth rotating shaft 42 is located at the front side of the first rotating shaft 31, and the second rotating shaft 11 and the fourth rotating shaft 42 are located at the same side of the rear leg 2. Preferably, the fourth rotating shaft 42 is located at the front side of the second rotating shaft 11. So that the front foot 1 can rotate about the fourth axis of rotation 42.

In this embodiment, preferably, when the stroller frame a is in the unfolded state, the second pivot 11 is located between the first pivot 31 and the fourth pivot 42. Therefore, the whole baby carriage bracket A is simpler in structure.

In the present embodiment, when the stroller frame a is in the unfolded state, the third rotating shaft 41 is located at the front side of the first rotating shaft 31; specifically, the third rotating shaft 41 is located at the front upper side of the first rotating shaft 31.

When the stroller frame a is in the unfolded state, the third rotating shaft 41 is located at the rear upper side of the fourth rotating shaft 42.

Due to the adoption of the structure, when the baby carriage support A is folded, the lower side of the first connecting piece 3 can rotate upwards only by rotating the upper side of the first connecting piece 3 backwards and downwards, and the rear side of the front leg 1 can be driven by the lower side of the first connecting piece 3 to rotate upwards together, so that the front side of the front leg 1 can rotate towards the rear leg 2 and the second connecting piece 4 can also be pulled to rotate towards the rear leg 2 (as shown in figures 3 and 4); until the components can not rotate relatively to approach each other, the baby carriage support A is folded, and at the moment, the front foot 1, the first connecting piece 3 and the second connecting piece 4 are close to the rear foot 2 relatively (as shown in figures 5 and 6), so that the baby carriage support A has small integral volume after being folded, and is convenient to carry and store.

As described above, because each component of the stroller bracket a of the present invention forms a four-bar linkage structure, due to the characteristics of the four-bar linkage structure, each component is very smoothly linked when being folded, so that the folding operation is very labor-saving, and each component is relatively closed after being folded, so that the size is small, and the stroller bracket a is convenient to carry and store; in addition, the relative relationship of the specific pivoting positions of the components of the baby carriage support A, namely the first connecting piece 3 and the rear leg 2 are in cross pivoting, the second rotating shaft 11 connecting the rear side of the front leg 1 and the first connecting piece 3 is positioned at the front side of the rear leg 2, so that relative to the pivoting positions of the first connecting piece 3 and the rear leg 2, two ends of the first connecting piece 3 form two ends of a seesaw to form a lever principle, and the relative pivoting positions of the second connecting piece 4, the front leg 1 and the rear leg 2 are combined, so that when the upper side of the first connecting piece 3 rotates backwards and downwards, the lower side of the first connecting piece can easily drive other components of the support to rotate and move, and the folding operation of the baby carriage support A is more labor-saving.

Preferably, the length of the first connecting element 3 from the upper end to the position pivoted to the rear leg 2 is greater than the length of the first connecting element from the position pivoted to the rear leg 2 to the position pivoted to the rear side of the front leg 1, that is, the length of the first connecting element 3 from the upper end to the position of the first rotating shaft 31 is greater than the length of the first rotating shaft 31 to the position of the second rotating shaft 11. With such an arrangement, the power arm is longer, and the first connecting piece 3 is rotated backwards and downwards to drive other components of the support to rotate, so that labor is saved, and the folding operation of the baby carriage support A is further more labor-saving.

The front lower part of the front foot 1 is connected with a front wheel 5, and the rear lower part of the rear foot 2 is connected with a rear wheel 6. When the baby carriage support A is in the unfolding state, the front wheels 5 and the rear wheels 6 are supported on the ground.

The invention also discloses a baby carriage frame which can be switched between an unfolded state and a folded state, the baby carriage frame comprises the baby carriage support A, a push handle 7 and a third connecting piece 8, the upper sides of the first connecting piece 3 and the third connecting piece 8 are respectively pivoted at different positions of the push handle 7, the lower side of the third connecting piece 8 is pivoted at the rear foot 2, and the lower sides of the first connecting piece 3 and the third connecting piece 8 are respectively pivoted at different positions of the rear foot 2, so that the push handle 7, the first connecting piece 3, the third connecting piece 8 and the rear foot 2 form a four-link structure.

The lower side of the third connecting member 8 is pivotally connected to the rear leg 2 via a fifth shaft 81, in this embodiment, the fifth shaft 81 is located at the rear side of the first shaft 31.

Correspondingly, the upper side of the first connecting member 3 is pivotally connected to the handle 7 through a sixth rotating shaft 31, the upper side of the third connecting member 8 is pivotally connected to the handle 7 through a seventh pivot 82, and when the stroller frame is in the unfolded state, the seventh pivot 82 is located at the lower side of the sixth rotating shaft 32.

When the stroller frame of the present invention is to be folded, only the lower side of the push handle 7 is rotated backward and downward and the upper side of the push handle 7 is rotated forward at the same time, the upper sides of the first connecting member 3 and the third connecting member 8 are both driven to rotate backward and downward to approach the rear leg 2 (as shown in fig. 3 and 4), and the upper side of the first connecting member 3 is rotated backward and downward to drive the other components of the stroller frame a to rotate and approach each other as described above until the components of the stroller frame of the present invention can not rotate and approach each other any more, because of the characteristics of the four-bar linkage mechanism, after the stroller frame of the present invention is folded, the push handle 7, the first connecting member 3, the third connecting member 8 and the rear leg 2 are also drawn together, and the front leg 1, the rear leg 2, the first connecting member 3 and the second connecting member 4 which form another four-bar linkage structure are also drawn together, so that all the components of the baby carriage frame are close to each other. Moreover, because the rear foot 2, the first two connecting pieces, the front foot 1 and the second connecting piece 4 of the baby carriage frame are formed into a four-steel structure, and the push handle 7 and the third connecting piece 8 are also formed into a four-bar structure, due to the characteristics of the four-bar structure and the first connecting piece 3 and the rear foot 2 shared by the two four-bar structures, when the baby carriage frame is folded again, the linkage of all components of the baby carriage frame is very smooth, namely the folding operation of the baby carriage frame is very labor-saving.

In the above description of the front-rear vertical orientation, the push handle 7 is located at the upper position and the front and rear wheels 5, 6 are located at the lower position, with the front wheel 5 located at the front and the rear wheel 6 located at the rear.
