7. A child safety seat rotation control method applied to a child safety seat according to any one of claims 1 to 3, comprising:

step S1: after the seat is installed, the second sensors (4) on the two sides of the seat detect the distance from the seat to the doors on the two sides, the seat is judged to be positioned on the side close to the doors, and the next step is executed;

step S2: the second sensor (4) and/or the third sensor (5) detects the opening of the same-side door, and if the opening of the same-side door is detected, the next step is executed;

step S3: the chair body (2) rotates towards the door opening side.

8. The child safety seat rotation control method according to claim 7, wherein: further included between the step S2 and the step S3 is: step S21: the first sensor (3) detects a child signal, and if the first sensor (3) does not detect the signal, the first sensor determines that no child is on the chair body (2), the next step is executed; if the first sensor (3) detects a signal, and the child is judged to be on the chair body (2), the manual control mode is entered.

9. The child safety seat rotation control method according to claim 8, wherein: the step S3 further includes: step S4: when the first sensor (3) detects a signal in a state that the chair body (2) faces the door opening side, and the chair body (2) does not rotate to return to the original position after the set time is exceeded, the loudspeaker prompts and gives an alarm.

10. The child safety seat rotation control method according to claim 7, wherein: in the step S2, the second sensor (4) and the third sensor (5) synchronously detect the opening of the same-side vehicle door, and if any one of the second sensor (4) and the third sensor (5) detects a signal, the next step is executed.

11. The child safety seat rotation control method according to claim 7, wherein: further included between the step S2 and the step S3 is: step S22: the second sensor (4) and/or the third sensor (5) detects an obstacle on the vehicle seat, and if no signal is detected, the next step is executed; if the signal is detected, it is determined that there is an obstacle, and the manual control mode is entered.

12. The child safety seat rotation control method according to claim 7, wherein: the step S1 further includes: step S0: the mobile phone APP is connected with the seat, and the installation position of the seat is set on the mobile phone APP; the step S1 and the step S2 further include: step S11: judging the seat position judged on the seat and the seat position in the mobile phone APP, and executing the next step if the seat position judged on the seat is consistent with the seat position in the mobile phone APP; if the two types of the seat positions are inconsistent, a manual control mode is entered, and a 'seat position setting error or a sensor error' is simultaneously prompted on the mobile phone APP.

13. The child safety seat rotation control method according to claim 7, wherein: the step S4 further includes: step S5: in a state that the chair body (2) faces to the door opening side, the second sensor (4) and/or the third sensor (5) detect the closing of the same-side door, and when the same-side door is closed, the chair body (2) rotates to return to the original position.

14. A method of controlling the wind-break of a child safety seat according to any one of claims 4 to 6, comprising:

step S6: the first sensor (3) detects a child signal, and if the first sensor (3) detects the signal, the first sensor determines that a child is on the chair body (2), the next step is executed;

step S7: the fourth sensor (8) detects the opening of the vehicle window, and if the fourth sensor (8) detects the opening of the vehicle window, the next step is executed;

step S8: the horn on the seat prompts the closing of the window or prompts the opening of the window.

15. The method for controlling the wind prevention of a child safety seat according to claim 14, wherein: the fourth sensor (8) in the step S7 detects the opening of the vehicle window, namely the opening time of the vehicle window glass exceeds 5-30 minutes.

16. The method for controlling the wind prevention of a child safety seat according to claim 14, wherein: the step S6 further includes: step S1: after the seat is installed, the second sensors (4) on the two sides of the seat detect the distance from the seat to the doors on the two sides, and the seat is judged to be positioned on the side close to the doors; the step S1 further includes: step S0: the mobile phone APP is connected with the seat, and the installation position of the seat is set on the mobile phone APP; the step S1 and the step S6 further include: step S11: judging the seat position judged on the seat and the seat position in the mobile phone APP, and executing the next step if the seat position judged on the seat is consistent with the seat position in the mobile phone APP; if the two types of the seat positions are inconsistent, a manual control mode is entered, and a 'seat position setting error or a sensor error' is simultaneously prompted on the mobile phone APP.
