Abstract
A wheeled automotive child safety seat comprises a safety seat body, left and right armrests of the safety seat body, a wheeled support and an ISOFIX (international standards organization FIX) interface support. A front transverse beam and a rear transverse beam are arranged at the front and rear ends of the wheeled support respectively. A main beam body in an arc shape is arranged between the front beam and the rear beam. Two arc grooved slides are arranged in the left and right armrests of the seat body respectively. The main beam body of the wheeled support is disposed in the arc grooved slides and capable of sliding back and forth. A front groove is arranged on the seat body at the front end of each grooved slide, and a rear groove is arranged at the rear end of the seat body. An armrest rear gap space is arranged at the tail end of each armrest. A bottom groove for containing the ISOFIX interface support is arranged at the bottom of the seat body. The ISOFIX interface support is in a telescopic structure. The arc main beam of the wheeled support moves forward along the arc grooved slides to enable the seat to move with four wheels touching the ground, and the arc main beam of the wheeled support moves back to enable the seat to be fixed so that the arc main beam of the wheeled support can be disposed at a preset ISOFIX interface of the automotive seat through the ISOFIX interface support. Practicality and cost performance of the original wheeled automotive child safety seat are expanded, and new technological applications of automotive child safety seats are created.
