Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-5, the utility model provides a baby carriage capable of reversing by seat rotation, which comprises a seat base 4, a seat 3 disposed above the seat base 4 and capable of rotating in the transverse plane direction relative to the seat base 4, a push rod 1 and a backrest 2 assembled on the seat 3 and capable of rotating in the longitudinal plane direction, a multi-link sliding mechanism disposed below the seat base 4 for realizing the folding of the baby carriage in the non-use state;

the multi-connecting-rod sliding mechanism further comprises a front wheel assembly 6 and a rear wheel assembly 11 which are arranged at the bottom of the multi-connecting-rod sliding mechanism; for example, the front wheel assembly 6 can be universal wheels, and the rear wheel assembly does not need to be used, so that the direction control in the pushing process is facilitated.

In this embodiment, the multi-link sliding mechanism includes a front bracket 5, a front link 7, a sliding sleeve 8, a rear link 9 and a rear bracket 10, one end of the rear bracket 10 is hinged to the seat base 4, the other end of the rear bracket is connected to the rear wheel assembly 11, and the sliding sleeve 8 is sleeved on the rear bracket 10 and can slide along the length direction of the rear bracket 10.

In this embodiment, as shown in fig. 1, the front bracket 5 is hinged to the rear bracket 10 at one end and is connected to the front wheel assembly 6 at the other end. One end of the rear connecting rod 9 is hinged with the seat base 4, the other end of the rear connecting rod is hinged with the sliding sleeve 8, one end of the front connecting rod 7 is hinged with the front support 5, and the other end of the front connecting rod is hinged with the rear connecting rod 9.

It should be noted that, in some embodiments (not shown in the drawings), of course, one end of the front bracket 5 may be hinged to the seat base 4.

It can be further understood that the other end of the front connecting rod 7 can also be hinged to the sliding sleeve 8, and when the front connecting rod 7 is hinged to the sliding sleeve 8, the other end of the rear connecting rod 9 can be hinged to the sliding sleeve 8, or hinged to the front connecting rod 7.

Similarly, when the other end of the rear connecting rod 9 is hinged to the sliding sleeve 8, the front connecting rod 7 can be hinged to the rear connecting rod 9 or hinged to the sliding sleeve 8.

For better understanding of the rotation of the seat plate 3 relative to the seat plate base 4, as shown in fig. 2:

the bottom of the seat plate 3 is provided with a convex disc 31, the top of the seat plate base 4 is provided with a concave disc 41 matched with the convex disc 31, and the convex disc 31 can rotate in the concave disc 41.

In order to prevent the convex disc 31 and the concave disc 41 from being separated from each other, for example (but not limited to this way, it can also be magnetic attraction, etc.), a snap ring structure is disposed on the outer wall of the convex disc, and a concave ring structure is disposed on the inner wall of the concave disc 41, and the snap ring structure is rotatably engaged in the concave ring structure. Thus, the seat plate 3 and the relative seat plate base 4 can rotate, and the seat plate 3 and the relative seat plate base 4 can not be separated.

The push rod 1 adopts a foldable structure or a telescopic structure, and the size after folding can be further reduced by the design of the structure.

The distance between the low point on the seat plate 3 and the hinge point between the rear support 10 and the seat plate base 4 is less than 20 cm.

The distance between the low point on the seat plate 3 and the hinge point between the front bracket 5 and the seat plate base 4 or the hinge point between the front bracket 5 and the rear bracket 10 is less than 20 cm.

It is understood that, when folding is performed, it is preferable to perform the folding operation when the seat board is rotated to the reverse direction, but it is not limited to performing the folding operation when the seat board is rotated to the reverse direction.

When the folding chair is folded, the push rod 1 and the backrest 2 are hinged with the seat plate 3, so that the backrest 2 and the push rod 1 are firstly rotated relative to the seat plate 3, and the seat plate 3, the backrest 2 and the push rod 1 are mutually folded.

Then, the multi-link sliding mechanism is used for further folding, and the sliding sleeve 8 can slide on the rear bracket 10. When the seat base 4 rotates around the hinge point of the rear support 10 and the seat base 4 relative to the rear support 10, the seat base 4 can drive the rear connecting rod 9 to move, the rear connecting rod 9 can drive the sliding sleeve 8 to slide on the rear support 10, meanwhile, the rear connecting rod 9 can drive the front connecting rod 7 to move, and the front connecting rod 7 drives the front support assembly 5 to move. The folded state refers to fig. 5.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
