That is to say, the side impact protection mechanisms 100 and the limiting members 130 are disposed on both sides of the seat body 110, after a child sits on the seat, the side impact protection blocks 10 on both sides of the seat body 110 can automatically spring open and automatically return to the working state from the retracted state, and in the using process of the child safety seat 200, if an accident occurs and a side impact occurs, the side impact protection blocks 10 firstly collide with the vehicle body to buffer the impact force, thereby playing a better protection role. Meanwhile, the limiting member 130 on the seat body 110 can be used to lock the side impact protection block 10 on one side of the two sides of the seat body 110, so that the side impact protection block 10 is positioned in the folded state, and after a child sits on the seat, the side impact protection block 10 cannot automatically bounce, thereby reducing the occupied space and increasing the convenience of use.

The operation principle and process of the child safety seat according to the present embodiment will be described with reference to fig. 1 to 15.

When the child safety seat 200 needs to be used, the child safety seat 200 is installed in the vehicle, and the side impact protection block 10 at the side far away from the vehicle door does not need to be used, so that the limiting member 130 at the same side as the side impact protection block 10 is operated to rotate around the rotating shaft, so that the limiting convex portion 1311 is located at the positioning convex portion 1113, that is, the limiting member 130 can lock the side impact protection block 10 to limit the side impact protection block 10 from automatically moving from the folded state to the working state; the side impact protection block 10 near one side of the vehicle door is needed, therefore, the limiting member 130 at the side is operated to rotate around the rotating shaft, so that the limiting protrusion 1311 is located in the positioning groove 1111, i.e. the limiting member 130 releases the side impact protection block 10, so that the side impact protection block 10 can automatically move from the folded state to the working state.

When a user sits on the child safety seat 200, the pivotal member 51 is pressed to drive the pulling member 60, so that the pulling member 73 is driven by the pulling member 60 to move on the inner cover 83 by a certain distance, such as the direction K in the figure, so that the elastic first protrusion 733 drives the second protrusion 715, the rotating rod 71 rotates on the inner cover 83, the mounting end 711 moves in the groove 833, the magnetic force adsorbing portion 21 and the magnetic force adsorbing and matching portion 23 are detached from adsorption, and under the action of the elastic portion 30, the side impact protection block 10 not locked by the limiting member 130 returns to the working state from the folded state, so that the child safety seat 200 can be protected from the impact of the lateral movement of the child seat, and the side impact protection block 1011 locked by the limiting member 130 is still in the folded state.

Compared with the prior art, since the child safety seat 200 of the present invention includes the seat body 110, the side impact protection mechanism 100 and the limiting member 130, the side impact protection block 10 can automatically return to the working state from the retracted state after the child sits on the seat. One end of the limiting member 130 is movably mounted on the side wing 111, when the limiting member 130 is operated to move, the other end of the limiting member 130 can extend to the side impact protection block 10 to limit the side impact protection block 10 from moving from the folded state to the working state, and the other end of the limiting member 130 can be operated to convert the side impact protection block 10 from the locking state to the unlocking state, so that the side impact protection block 10 can move from the folded state to the working state. When the child safety seat 200 is installed on an automobile, the side impact protection block 10 at a side away from the door does not need to be used, so that the side impact protection block 10 can be locked by using the limiting member 130, the side impact protection block 10 is positioned in a folded state, and after a child sits on the seat, the side impact protection block 10 cannot automatically bounce, so that the occupied space is reduced, and the convenience in use is improved.

The present invention has been described in connection with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, and is intended to cover various modifications, equivalent combinations, which are made in accordance with the spirit of the present invention.
