The invention discloses a child safety seat and a side collision protection mechanism thereof, and the side collision protection mechanism is arranged at a backrest of the child safety seat and comprises a side collision protection block and a self-locking structure. The side collision protection block is movably assembled on the backrest and is provided with a folding position capable of being folded inwards to the backrest and an unfolding position capable of being unfolded outwards from the backrest. The self-locking structure automatically moves to a position where the side collision protection block at the exhibition position is prevented from being switched to the folding position when the side collision protection block is switched to the exhibition position from the folding position, the self-locking structure is assembled on the side collision protection block or the backrest, and the backrest and/or the side collision protection block shield the self-locking structure to prevent an operator from unlocking the self-locking structure; therefore, the side collision protection block cannot be folded inwards on the backrest after being used for the first time, and the situation that the side collision protection block cannot provide the side collision effect due to accidental folding in the side collision process is effectively prevented.

    本发明公开了一种儿童安全座椅及其侧撞保护机构,该侧撞保护机构设于儿童安全座椅的背靠处,包括侧撞保护块及自锁结构。侧撞保护块活动地装配于背靠并具有可向内收合于背靠的收合位置和向外展出背靠的展出位置;自锁结构在侧撞保护块由收合位置切换至展出位置时自动活动至阻挡展出位置的侧撞保护块往收合位置切换的位置,自锁结构装配于侧撞保护块或背靠,且背靠和/侧撞保护块遮挡自锁结构以阻挡操作人员对自锁结构的释锁操作;以在侧撞保护块首次使用后不可再向内收合于背靠,有效地防止侧撞保护块在侧撞过程中因意外收合而无法提供侧撞作用。
