Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

In describing the present invention, it should be understood that the terms "center", "transverse", "longitudinal", "front", "rear", "left", "right", "upper", "lower", " The orientations or positional relationships indicated by "vertical", "horizontal", "top", "bottom", "inner" and "outer" are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and Simplified descriptions, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and thus should not be construed as limiting the scope of the present invention.

As shown in Figures 1 and 2, in a schematic embodiment of the ISOFIX connection device for a child safety seat provided by the present invention, the ISOFIX connection device includes a pair of ISOFIX joints 10, respectively connected to the base 100 of the child safety seat connected and can be folded towards each other for storage.

Optionally, one of the pair of ISOFIX joints 10 is connected to the left side of the base 100 , and the other of the pair of ISOFIX joints 10 is connected to the right side of the base 100 . The two ISOFIX joints 10 can be folded inward relative to each other for storage. When folded, the two ISOFIX joints 10 and the base 100 are always in the same plane.

In the above exemplary embodiment, a pair of ISOFIX joints 10 can be folded toward each other, so that when not in use, the storage of the ISOFIX joints 10 can be realized by folding, which is convenient for transportation; and the folding method of a pair of ISOFIX joints 10 is toward They are folded in opposite directions, which is not only more convenient and labor-saving to operate, but also has good safety.

Specifically, in related technologies, the ISOFIX joint and the connecting rod connected to the ISOFIX joint are turned backwards by 180° as a whole, so as to turn the whole of the ISOFIX joint and the connecting rod under the base of the child safety seat, although this can also achieve The storage of ISOFIX joints, but this method needs to completely lift up the entire child safety seat when turning over, leaving enough turning space for the ISOFIX joints and connecting rods as a whole, which is time-consuming and laborious; and in the embodiment of the present invention, the ISOFIX The storage can be realized by folding the joint inward, and the operation mode is more in line with human operating habits, and it is not necessary to lift the entire child safety seat completely, saving time and effort. In addition, when the child safety seat is collided in the forward direction, the child occupant is bound by the restraint system and will drive the seat back to flip forward. At this time, all the force that restricts the seat flip falls on the connecting rod connected to the IOSFIX joint. In fact, if the storage method in the above-mentioned related art is used, the connecting rod can be rotated in the direction of the force, which will increase the risk of the seat turning over, so the safety of this storage method is relatively poor; and in the present invention In the embodiment, even if the force that restricts the flipping of the seat falls on the connecting rod connected to the IOSFIX joint, it will not increase the risk of the flipping of the seat, and the connecting rod can be rigidly connected in the forward flipping direction of the seat , good security.
