Technical Field

[0001] The utility model belongs to the technical field of child seats, in particular to a head and neck protection structure of a vehicle-mounted child safety seat. Background Art

[0002] A car child safety seat is a seat fixed on a car seat for protecting children. Depending on the different protection ranges for the body, it can provide head and neck protection, trunk protection, and limb protection. The head and neck protection structure of an existing car child safety seat, such as the head and neck protection structure of a car child safety seat disclosed in application number CN202322248304.7, can facilitate the installation and disassembly of the protective jacket and the installation support pad through the arranged installation connection blocks, installation slide holes, locking installation grooves, concave installation grooves, and fixing nuts, so as to facilitate replacement and increase the stability of the protection for the child's head and neck. At the same time, it can also effectively increase the convenience and stability of the installation of the protective jacket and the installation support pad.

[0003] However, in actual use, the head and neck protection structure of the existing vehicle-mounted child safety seat is fixed, and the angle of the protection structure on both sides of the neck cannot be adjusted according to the actual needs of the child, so that the inner wall cannot fit the neck skin, resulting in low protection. When encountering danger, the neck is easily injured by shaking, and the overall structure is fixed. It is difficult to play an effective buffering role in collisions by relying solely on protective jackets. For this reason, we propose a head and neck protection structure for a vehicle-mounted child safety seat to solve the above problems. Utility Model Content
