Supporting leg assembly of child safety seat

Abstract

The invention discloses a supporting leg assembly of a child safety seat. A middle square pipe is sleeved with a supporting base which is supported by a vehicle bottom plate. An elastic locking mechanism is arranged on the supporting base and comprises hinge pins which are matched with a first locking hole and a second locking hole, a first inclined plane is arranged on the inner side of the supporting base, and a second inclined plane is arranged on the outer side of a locking block. When the first inclined plane of the supporting base presses the second inclined plane of the locking block, the front end of the locking block retracts into the inner wall of the middle square pipe. The supporting leg assembly has the advantages that a user can adjust the height of the supporting leg assembly only by pushing upwards or pulling downwards the supporting base with one hand, operation is convenient to conduct, the adjusting range of the height of supporting legs can be extended to 260 mm, and therefore the adaptability requirement of supporting legs of all vehicles with ISOFIX connectors on current domestic and foreign markets can be met.

Description

technical field [0001] The invention relates to a child safety seat, in particular to a supporting leg assembly of the child safety seat. Background technique [0002] In the field of child safety seats, ISOFIX child safety seats are well known, and the supporting legs are one of the most common anti-rolling devices of ISOFIX child safety seats. The birth of car child safety seats is much later than the development of the automobile industry. , so the height between the seat plane of the car seat and the car floor is not the same, even the difference between high-end models and compact models is very large, in order to meet the installation requirements of different models as much as possible and consider the support In terms of strength, the supporting leg structure equipped on the general child safety seat is designed as a height-adjustable two-stage structure. However, due to structural limitations, the height adjustment range of the general supporting leg can only be des...

[0002] In the field of child safety seats, ISOFIX child safety seats are well known, and the supporting legs are one of the most common anti-rolling devices of ISOFIX child safety seats. The birth of car child safety seats is much later than the development of the automobile industry. , so the height between the seat plane of the car seat and the car floor is not the same, even the difference between high-end models and compact models is very large, in order to meet the installation requirements of different models as much as possible and consider the support In terms of strength, the supporting leg structure equipped on the general child safety seat is designed as a height-adjustable two-stage structure. However, due to structural limitations, the height adjustment range of the general supporting leg can only be designed to a maximum of about 200mm, or even lower. Cannot meet the ISOFIX child safety seat used in all cars with ISOFIX interface, in order to solve the adaptability between the supporting legs of the ISOFIX child safety seat and the car seat, the designer will consider designing more than three sections of support Leg assembly, but at the same time it will cause the problem of inconvenient operation
