Problems solved by technology
This technical solution still has the following problems: 1. When unfolding, the front frame, the side rod and the push rod frame are unfolded into a straight line, and the locking mechanism locks the car body by squeezing the push rod frame and the side rod. It is necessary to push the push rod frame to rotate to form a lever to fold, which is not only inconvenient to fold, but also requires a lot of force, and the force is concentrated, which is easy to damage the push rod frame; 2. The push rod frame adopts two-stage telescopic, and the length is still long Long, the front frame cannot be folded and the length is too long, so that the frame is still bulky after being folded; 3. If you need to fold the rear wheels together to make the frame smaller, you need to squat down first and then fold it After the rear wheels are put away by the frame, the two side supports are then folded. The operation is inconvenient, the process is unreasonable, and the requirements for the use skills are too high; , it is inconvenient to collect and use; 5. The locking mechanism and multiple joint mechanisms are exposed, which is easy to cause harm to children and affect the safety of use
This solution adopts the chassis seat structure. In order to ensure the stability of the frame, the chassis seat is bulky and cannot be folded, so that the folded frame is still large in size, although it also shows that the push rod can be retracted or folded. Yes, a simple bending structure is also given, but even after the push rod is bent, the frame volume is still large

Embodiment approach
[0101] The above-mentioned push-up lever locking mechanism can adopt the structure that has been used in the folding cart in the prior art, and the present invention adopts a preferred implementation mode, which is described as follows:
[0102] like Figure 12 , Figure 13 As shown, the upper push handle locking mechanism includes an upper push handle telescopic switch 6111, an upper push handle lock pin 613, a shrapnel 614 and a shrapnel cover 612, the shrapnel 614 is fixed on the insertion part where the upper push handle rod 61 is inserted into the middle push handle rod 62, and the shrapnel 614 The outer warping end fixes the locking pin 613 of the upper push handle, and the upper push handle lock pin 613 extends out of the upper push handle 61 and cooperates with the locking pin hole on the middle push handle 62. The shrapnel sleeve 612 is set outside the shrapnel 614 and controls the shrapnel by sliding. The outer warped end of 614 is brought in or warped out, and the ...

The invention discloses a baby carriage, a carriage furling mechanism and a carriage furling and folding method. The carriage furling mechanism comprises two side frames and a horizontal lever, wherein each of the side frames comprises a front foot lever, a rear foot lever and a push lever; a front supporting lever and a rear supporting lever are connected between each front foot lever and the corresponding push lever, and a foldable first four-connecting-lever mechanism is formed; a first connecting lever and a second connecting lever are sequentially connected between each front foot lever and the corresponding rear foot lever, and a second four-connecting-lever mechanism is formed; one end of each of the first connecting levers and the lower end of the corresponding front supporting lever are fixedly connected or integrally formed; each first four-connecting-lever mechanism in a folding state is overlaid on the upper side of the corresponding front foot lever, and each rear foot lever is overlaid on the lower side of the corresponding front foot lever; and the upper end of each rear supporting lever and the middle part of the corresponding push lever are locked and fixedly connected, or released, furled and folded through a carriage furling and locking mechanism. The technical scheme of the baby carriage disclosed by the invention is more reasonable in structure; the size of the folded baby carriage is low; and the operation of the baby carriage is convenient and effortless.
Description
technical field [0001] The invention relates to the technical field of children's trolleys, in particular to a foldable children's trolley, its retracting mechanism, and its folding method. Background technique [0002] Stroller is a tool cart designed for the convenience of baby's outdoor activities. It is the baby's favorite means of transportation for walking, and it is also a must-have for mothers when they take their baby to the street for shopping. With the progress of production and life, there are more and more usage scenarios of baby carriages. [0003] The Chinese patent document with publication number CN101544242 discloses a foldable stroller, which belongs to the technical field of folding mechanism structure. A foldable stroller, comprising a push rod and a front wheel bracket and a rear wheel bracket with wheels at the bottom, characterized in that the front wheel bracket and the rear wheel bracket are movably connected to the upper push rod through a center ...
