Child safety seat and electric angle adjustment device thereof

A child safety seat, comprising:

• a base;
• a seat body slidably assembled on the base along a front-rear direction of the base, the seat body is angularly adjusted with respect to the base during a sliding process;
• an electric angle adjustment device disposed between a seat body and the base, the electric angle adjustment device comprising:
• a motor,
• a rotating member,
• a sliding member, and
• an intermediate transmission assembly, wherein:
• the rotating member extends along a sliding direction of the seat body, the motor is disposed on one of the seat body and the base, and an output shaft of the motor extends along a left-right direction or an up-down direction of the base, such that the output shaft of the motor is arranged intersecting with the rotating member,
• the sliding member is assembled on the other one of the seat body and the base, the sliding member is also slidably arranged on the rotating member,
• the intermediate transmission assembly is assembled on both the output shaft of the motor and the rotating member;
• the motor is configured to drive the rotating member to rotate through the intermediate transmission assembly, and
• the sliding member is configured to slide on the rotating member upon rotation of the rotating member, thereby electrically adjusting an angle of the seat body with respect to the base;
• and
• a transverse rod arranged on and protruding from the sliding member along a left-right direction of the seat body, the transverse rod configured to slide with the sliding member, wherein the seat body or the base where the motor is located is correspondingly provided with an arc guide passage, the transverse rod is placed in the arc guide passage in a clearance fit and is configured to perform a curve sliding along the arc guide passage, and the seat body or the base where the sliding member is located is connected to the transverse rod.
