Detailed Description
As shown in fig. 1 to 6, the frame of the stroller of the present invention can be switched between an unfolded state and a folded state, the frame includes a push handle 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4, a front leg 5, and a rear leg 6, the upper sides of the first connecting rod 2 and the second connecting rod 3 are rotatably connected to the push handle 1 and connected to different positions of the push handle 1, the lower sides of the first connecting rod 2 and the second connecting rod 3 are rotatably connected to the third connecting rod 4 and connected to different positions of the third connecting rod 4, and the push handle 1, the first connecting rod 2, the second connecting rod 3, and the third connecting rod 4 are formed into a four-bar structure; the rear side of the front foot 5 is rotationally connected with the first connecting rod 2 or the third connecting rod 4, or the rear side of the front foot 5 is coaxially and rotationally connected with the first connecting rod 2 and the third connecting rod 4; the front side of the rear foot 6 is rotatably connected with the front foot 5, and the second connecting rod 3 is also rotatably connected with the rear foot 6.
In the present embodiment, the third link 4 is rotatably connected to the first link 2 at the upper side and rotatably connected to the second link 3 at the lower side.
The second connecting rod 3 is in cross rotating connection with the rear foot 6, and two sides of the second connecting rod 3 are respectively in rotating connection with the push handle 1 and the third connecting rod 4.
The rear side of the front foot 5 is rotatably connected with the first link 2 or the third link 4 around a first rotating shaft, or the rear side of the front foot 5, the first link 2 and the third link 4 are coaxially and rotatably connected through a first rotating shaft 51; the rear leg 6 is connected to the front leg 5 at a front side thereof so as to be rotatable about a second pivot 52, and the first pivot 51 is located at a rear side of the second pivot 52 when the stroller frame is in the unfolded state. In this way, during the folding process of the frame, the front leg 5 can rotate relative to the rear leg 6 by using the second rotating shaft 52 as a rotating shaft. Preferably, the first rotating shaft 51 is located at the rear upper side of the second rotating shaft 52.
Preferably, in this embodiment, the rear side of the front foot 5, the lower side of the first link 2, and the front side of the third link 4 are coaxially and rotatably connected through the first rotating shaft 51, so that the assembly is more convenient, and the overall frame is simpler.
The second link 3 is connected to the rear leg 6 in a rotatable manner about a third pivot axis 31, and the second pivot axis 52 is located on the front side of the third pivot axis 31 when the stroller frame is in the unfolded state. The lower side of the third link 4 is connected to the lower side of the second link 3 in a manner of rotating around a fourth rotating shaft 32, and the fourth rotating shaft 32 is positioned at the lower side of the third rotating shaft 31 when the baby carriage frame is in the unfolding state. With such an arrangement, when the second link 3 rotates backward and downward, the lower side thereof can drive the lower side of the third link 4 to rotate backward, so that the upper side of the third link 4 can rotate forward, and further the lower side of the front foot 5 is driven to rotate backward by using the second rotating shaft 52 as a rotating shaft.
The upper side of the first connecting rod 2 is connected with the push handle 1 in a rotating way around a fifth rotating shaft 11, the upper side of the second connecting rod 3 is connected with the push handle 1 in a rotating way around a sixth rotating shaft 12, and when the frame of the baby carriage is in an unfolded state, the fifth rotating shaft 11 is positioned on the upper side of the sixth rotating shaft 12. The third rotating shaft 31 is located between the fourth rotating shaft 32 and the sixth rotating shaft 12.
When the rear side of the front leg 5, the first link 2 and the third link 4 are rotatably connected together by the first rotating shaft 51, the first rotating shaft 51 is located on the upper side of the fourth rotating shaft 32 when the stroller frame is in the unfolded state. When the rear side of the front leg 5 is not connected with the first link 2 and the third link 4 in a rotating manner, the upper side of the third link 4 is connected with the lower side of the first link 2 in a rotating manner around a seventh rotating shaft, preferably, the seventh rotating shaft is located on the upper side of the fourth rotating shaft 32 when the frame of the baby carriage is in the unfolded state. With the arrangement, the push handle 1, the first connecting rod 2, the second connecting rod 3 and the third connecting rod 4 can form a four-connecting-rod structure, and the four-connecting-rod structure can be better connected with the front foot 5 and the rear foot 6, so that the frame is more compact.
When the stroller frame is in the unfolded state, the sixth rotating shaft 12 is located on the upper side of the third rotating shaft 31.
Because the utility model discloses bassinet frame adopts as above-mentioned structure to when folding the utility model discloses bassinet frame, only need to make push away the direction rotary motion that 1 downside is close to back foot 6 to the lower backward, and make simultaneously push away 1 upside and rotate forward, because the characteristic of four-bar linkage, first connecting rod 2 and 3 upside can be driven easily and close to the direction rotary motion of back foot 6 to the lower backward, thus first connecting rod 2 downside can promote the relative forward rotation of front foot 5 upside (use first pivot 51 as the rotation axis when front foot 5 rotates), so, front foot 5 downside then rotates backward and is close to back foot 6; when the upper side of the second connecting rod 3 rotates backwards and downwards, the lower side of the second connecting rod drives the lower side of the third connecting rod 4 to rotate backwards, so that the upper side of the third connecting rod 4 can rotate forwards relatively, and thus, the third connecting rod 4 can also push the upper side of the front foot 5 to rotate forwards, namely, the lower side of the front foot 5 rotates backwards to be close to the rear foot 6 (shown in figures 3 and 4), so that the front foot 5 can also be driven to rotate easily; until the push handle 1, the first connecting rod 2, the second connecting rod 3, the third connecting rod 4, the front foot 5 and the rear foot 6 are relatively close to each other, the frame is completely folded (as shown in figures 5 and 6). Therefore, when the frame is folded, only the lower side of the push handle 1 is required to rotate and move towards the direction of approaching the rear foot 6 towards the rear lower side, and simultaneously the upper side of the push handle 1 is required to rotate forwards, other components of the frame can be linked and rotated very easily and smoothly to approach each other, so that the folding operation is very labor-saving, and the vehicle folding burden of parents embracing a child can be reduced; moreover, because the frame is completely folded, all components of the frame are relatively close to each other, the whole volume of the folded frame is very small, and the folded frame is convenient to store and carry.
The front lower part of the front foot 5 is connected with a front wheel 7, and the rear lower part of the rear foot 6 is connected with a rear wheel 8.
The utility model also provides a bassinet, it includes above-mentioned bassinet frame. Because the bassinet frame has above-mentioned beneficial technological effect, the utility model discloses the bassinet also has above-mentioned beneficial technological effect.
In the above description of the orientation, the front wheel 7 is located at the front, the rear wheel 8 is located at the rear, the push handle 1 is located at the upper position, and the front wheel 7 and the rear wheel 8 are located at the lower position.
