Detailed Description
As shown in fig. 1, 2 and 3, the child stroller of the present invention comprises a frame 100 having a collapsed state and an expanded state, wherein the frame 100 comprises a rider 1, a first connecting rod 2, a second connecting rod 3, a third connecting rod 4, a fourth connecting rod 5, a fifth connecting rod 6, a front foot 7 and a rear foot 8; the upper end of the first connecting rod 2 is pivoted to a rider through a first pivot 11, the rear end of the second connecting rod 3 is pivoted to the rider 1 through a second pivot 12, and the first pivot 11 is positioned on the upper side of the second pivot 12; the third connecting rod 4 is pivoted with the first connecting rod 2 in a crossing manner, the upper end of the third connecting rod 4 is pivoted with the second connecting rod 3, and the lower end of the third connecting rod is pivoted with the front foot 7 or/and the rear foot 8; the front end of the fourth connecting rod 5 is pivoted to the lower end of the first connecting rod 2, and the rear end of the fourth connecting rod is pivoted to the rear foot 8; the front end of the fifth connecting rod 6 is pivoted with the front foot 7, and the rear end of the fifth connecting rod is pivoted with the fourth connecting rod 5; the rear side of the front foot 7 is pivoted with the front side of the rear foot 8.
When the child cart is folded, the rider 1 is moved back and downward, and simultaneously the rider 1 is rotated forward, so that the rear ends of the first connecting rod 2 and the second connecting rod 3 are driven to rotate back and downward; when the rear end of the first connecting rod 2 rotates backwards and downwards, the front end of the first connecting rod rotates forwards and upwards relatively, so that the front end of the fourth connecting rod 5 is pulled to rotate upwards, the rear foot 8 is driven by the fourth connecting rod 5 to rotate forwards and approach the front foot 7, and the upper end of the fifth connecting rod 6 is pulled by the fourth connecting rod 5 to rotate upwards; in the process that the rear ends of the first link 2 and the second link 3 are both rotated and moved downward and rearward, the third link 4 is pulled by the second link 3 and rotated downward and rearward (as shown in fig. 2), that is, the components of the frame 100 are smoothly linked until the front foot 7, the rear foot 8, the rider 1 and the first link 2 are rotated and folded toward each other, the second link 3 is substantially parallel to the first link 2, the third link 4 is also substantially parallel to the second link 3, that is, the second link 3 and the third link 4 are in a substantially straight line state, and the fourth link 5 and the fifth link 6 are also in a folded and folded state (as shown in fig. 3) which is rotated and folded toward the front foot 7 and the rear foot 8, so that the overall volume of the folded frame 100 is small.
The lower end of the third connecting rod 4 is pivoted to the front foot 7 or/and the rear foot 8, that is, the lower end of the third connecting rod 4 may be pivoted to the front foot 7 or the rear foot 8, or the lower end of the third connecting rod 4 is pivoted to the front foot 7 or the rear foot 8 through the same pivot. In this embodiment, preferably, the lower end of the third link 4 is pivotally connected to the upper side of the rear leg 8, so that the third link 4 can more conveniently rotate backward, and the rotated third link can more parallel to the rear leg 8 and also more in the same straight line state with the second link 3, so that the volume of the folded frame 100 is smaller.
In this embodiment, the upper end of the third link 4 is pivotally connected to the second link 3 through a third pivot 41, and the third pivot 41 is located at the front side of the second pivot 12.
The rear end of the front foot 7 is pivoted with the front end of the rear foot 8 through a fourth pivot 71, the rear end of the fourth connecting rod 5 is pivoted with the rear foot 8 through a fifth pivot 81, and the fifth pivot 81 is positioned at the lower side of the fourth pivot 71. So set up for when receipts, under the pulling of fourth connecting rod 5, front foot 7 and rear foot 8 can be close to as far as possible, and fourth connecting rod 5 can also have enough big rotational space moreover, also can be close to with the parallel state of rear foot 8 as far as possible, thereby make the frame 100 after receipts to wholly tend to be flatter, even make frame 100 receipts back volume littleer.
The front end of the fifth link 6 is pivotally connected to the front foot 7 through a sixth pivot 51, and the sixth pivot 51 is also located below the fourth pivot 71. By this arrangement, the fifth link 6 also has enough space to rotate closer to the front foot 7 during folding, and does not interfere with the approach of the front foot 7 to the rear foot 8, thereby reducing the volume of the folded frame 100.
Preferably, the lower ends of the first connecting rods 2 are parallel to the front sides of the front feet 7 when the frame 100 is in the unfolded state, so that the frame 100 is more compact in structure as a whole, and the front feet 7 can provide supporting force when the first connecting rods 2 are pressed downwards in the unfolded state of the frame 100, so that the frame 100 is more stable. The frame 100 further comprises a connecting piece 9, the lower end of the second connecting rod 3 is pivotally connected to the upper end of the connecting piece 9, the front end of the fourth connecting rod 5 is pivotally connected to the lower end of the connecting piece 9 (as shown in fig. 2 and 5), and the purpose that the lower end of the first connecting rod 2 is parallel to the front side of the front foot 7 is achieved through the arrangement of the connecting piece 9.
In this embodiment, the front leg 7 and the upper end of the rear leg 8 are preferably integrally formed in a downward arc shape when the frame 100 is in the unfolded state. By the arrangement, the whole frame 100 is more compact and attractive in appearance, and more importantly, when the frame 100 is folded, the front foot 7 and the rear foot 8 can be closer to each other except the upper ends, so that the volume of the folded frame is further reduced.
The stroller further comprises a front wheel 200 arranged at the front lower part of the frame 100 and a rear wheel 300 arranged at the rear lower part of the frame 100.
As shown in fig. 4, 5, 6 and 7, the frame 100 includes left and right side brackets 10 and lateral links connecting the side brackets 10, each of which includes the rider 1, the first link 2, the second link 3, the third link 4, the fourth link 5, the fifth link 6, the front foot 7 and the rear foot 8.
The transverse connecting rod comprises a rear connecting rod 101 with left and right ends respectively connected with the rear legs 8 of the left and right brackets or/and a front connecting rod 102 with left and right ends respectively connected with the front legs 7 of the left and right brackets.
In this embodiment, the left and right ends of the front link 102 are respectively connected to the lower ends of the left and right side support front legs 7, the front wheels 200 are provided with two wheels respectively disposed on the left and right sides of the front link 102, and the rear wheels 300 are provided with two wheels respectively disposed on the lower sides of the left and right side support rear legs 8.
