The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

As shown in fig. 1-4, a foldable stroller comprises a first rod 1, a second rod 2, a third rod 3, a fourth rod 4, an upper cross bar 5, a lower cross bar 6, a slidable push rod 9, front wheels 11, and rear wheels 12, wherein the first rod 1 is connected with the second rod 2 through two first shafts 71 to form a main frame; a fourth sliding sleeve 84, a third sliding sleeve 83 and a third shaft 73 are arranged on the first rod member 1; the first rod 1 is connected with one end of a third rod 3 through a third shaft 73, the other end of the third rod 3 is connected to the second shaft 72, and the third rod 3 is connected with a first sliding sleeve 81 in a sliding manner; the second shaft body 72 is sleeved on the top end of the fourth rod 4, the fourth rod 4 is connected with a second sliding sleeve 82 in a sliding manner, a short rod is connected between the second sliding sleeve 82 and the fifth sliding sleeve 85, and the second rod 2 is connected with the fifth sliding sleeve 85 in a sliding manner.

Wheel 11 before 2 bottoms of second member pieces are installed, rear wheel 12 is installed to 4 bottoms of fourth member pieces, preceding wheel, rear wheel are the wheel that adopts the EVA material. The front wheels 11 are universal wheels, the rear wheels 12 are fixed wheels, the lower cross rod 6 of the rear wheels is provided with a portable braking device 13, and the portable braking device is used for treading downwards to drive gears in the rear wheels so as to stop the left rear wheel and the right rear wheel to rotate and brake the left rear wheel and the right rear wheel, so that good braking performance can be provided, and the safety and the reliability are higher.

A slidable push rod 9 is arranged between the two fourth sliding sleeves 84, and is used for adjusting the proper height when being fixed on the back of the baby carriage seat. An upper cross bar 5 is fixedly connected between the second rod piece 2 and the fourth rod pieces 4, and a lower cross bar 6 is connected between the tail ends of the two fourth rod pieces for fixation and bidirectional connection; the top of third member 3 is connected with dinner plate 10 through third axis body 73, dinner plate 10 lower extreme is equipped with the support frame, support frame and the swing joint of the first axis body 71, the dinner plate adopts aluminum alloy material to make as major structure, the support frame then adopts stainless steel construction, strengthens its rigidity that supports the dinner plate, and two points of use of aluminum alloy dinner plate have strengthened the portability, and the colour can be diversified, and is pleasing to the eye and durable, and suitable decoration can be carried out to available plastic products, and wherein the colour of aluminum alloy and plastics can be diversified. The rod and the shaft are connected by small bolts. The overall volume of the folded baby carriage can be more flattened than that of the existing baby carriage.

The shopping cloth bag easy to fold is arranged between the lower portion of the second rod piece and the cross rod, and made of canvas, can be used for placing daily necessities of infants and other articles, does not influence the folding of the whole body of the baby carriage, and can be conveniently detached when not needed. Mounting bracket holes are formed in the second rod piece and the fourth rod piece, and the easily-folded shopping cloth bag is placed on the mounting bracket.

First member 1, second member 2, third member 3, fourth member 4, entablature 5, sheer pole 6, slidable push rod 9 all adopt the aluminum alloy ex-trusions to make, first axle body 71, second axle body 72, third axis body 73 all adopt the high-strength aluminum alloy ex-trusions to make, first sliding sleeve 81, second sliding sleeve 82, third sliding sleeve 83, fourth sliding sleeve 84, fifth sliding sleeve 85 all adopt the high-strength aluminum alloy ex-trusions to make, and above-mentioned member, axis body and sliding sleeve all adopt the high-strength 6061 aluminum alloy material to make.

When the baby carriage is used, the first rod piece 1 is pressed backwards in a folding mode, so that the first rod piece 1 and the second rod piece 2 rotate relative to the first shaft body.

Secondly, because the third rod 3 is linked with the first rod 1 to generate linkage, the third rod 3 rotates relatively between the second shaft 72 and the first rod 1, the second rod 2 slides relatively on the fifth sliding sleeve 85 and slides relatively on the first sliding sleeve 81, the fourth rod 4 is driven by rotation to slide relatively along the second sliding sleeve 82, so that the rear wheel is lifted to a certain height and gradually approaches to the upper part of the front wheel, and the basket is arranged to be folded flatly.

Finally, the dish 10 slides relatively in the connection between the first rod 1 and the third runner 83, rotates on the third shaft 83 and advances forward on the first rod, wherein the third runner pushes the fourth runner, so that the slidable push rod returns to the original position until the support, dish and first rod are parallel, at which time the first rod is close to the rear wheel, completing the flat folding. The folding mechanism realizes cooperative linkage.

When the third rod 3 is connected with the first rod 1 to generate linkage when folded, the third sliding sleeve 83 will push backwards to drive the third rod 3 to move, the third rod 3 rotates relatively between the second shaft 72 and the third shaft 73 and slides relatively on the first sliding sleeve 81, and drives the fourth rod 4 to slide relatively along the second sliding sleeve 82 when rotating, so that the first rod drives some components in the middle to move, and the second rod moves upwards under the first shaft which rotates and folds downwards and then is pulled, so that the second rod slides relatively on the fifth sliding sleeve, except for sliding when folded, the fifth sliding sleeve is connected with the second sliding sleeve to play a role of fixing the relative positions of the rods when folded to different positions.

The volume can be reduced after this novel folding, effectively reduces and places occupation space. This perambulator can realize the easy folding effect of light and convenient to reduce automobile body weight and take up an area of the space, conveniently realize going out of every family and play, shopping and go out folding on the driving and place in the door. The main material adopts high-strength aluminum alloy section bars, and has good bearing performance while being light. The production cost can be reduced during batch manufacturing production, and the packaging cost, the transportation cost and the human resources are reduced.

The embodiments described above are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
