[0026] Example 1

[0027] This embodiment is used to solve the problem that it is inconvenient to determine the side of the child seat close to the door in the prior art.

[0028] A child safety seat is provided as shown in Figures 1-6 The child safety seat comprises a base group 1, a rotary disc group 5 and a seat group 2. The seat group 2 is installed on the top of the rotary disc group 5, the rotary disc group 5 is installed on the top of the base group 1, and at least one second sensor group 4 is arranged on each side of the base group 1.

[0029] A first sensor 3 is arranged in the seat group 2. The first sensor 3 can be a pressure sensor. The first sensor 3 is used to detect whether a child is placed in the seat.

[0030] The base group 1 is provided with a first gear 6, a second gear 7 and a worm 8, the second gear 7 is in meshing connection with the worm 8, the first gear 6 is in meshing connection with the second gear 7, and the first gear 6 is fixedly connected with the rotating disc group 5. The base group 1 is provided with a driving group 9, and the driving group 9 is connected with the worm 8. The base group 1 is provided with a FIX interface 10. The base group 1 is provided with an operation module 11. The base group 1 is provided with a control system 12, the FIX interface 10 and the operation module 11 are electrically connected with the control system 12, and the control system 12 is electrically connected with the second sensor group 4. The base group 1 is provided with a power input unit 13, and the driving group 9, the FIX interface 10, the operation module 11 and the control system 12 are electrically connected with the power input unit 13. The driving group 9 is selected from a motor, the motor drives the worm 8 to rotate, the worm 8 drives the second gear 7 to rotate, the second gear 7 drives the first gear 6 to rotate, and the first gear 6 drives the rotating disc group 5 to rotate.

[0032] The seat group 2 is detachably connected with the rotating disc group 5. Optionally, the seat group 2 and the rotating disc group 5 are detachably connected through buckles.

[0033] Working principle:

[0034] S1: The child safety seat is installed and the FIX interface 10 on both sides is locked correctly. The second sensor 4-1 near the door side is touched or pressed. The second sensor 4-1 sends an electrical signal to the control system 12. The control system 12 confirms that the side of the second sensor 4-1 sending the electrical signal is the side where the child seat is placed. The position confirmation is maintained until a new position confirmation is made. When the FIX interface 10 is unlocked, the position of the second sensor 4-1 needs to be re-determined.

[0035] S2: The second sensor 4-1 detects whether the door on the same side is open. If it is open, S3 is executed. The second sensor 4-1 determines whether the door on the same side is open or closed according to the distance to the door on the same side.

[0036] S3: If the first sensor 3 does not detect a pressure signal, it is determined that there is no child in the seat. The rotating disc group 5 drives the seat group 2 to rotate towards the door side. If a pressure signal is detected, it is determined that there is a child in the seat. Manual control of the rotation of the seat group 2 through the operation module 11 is required to prevent the seat group 2 from rotating automatically and injuring the child.

[0037] S4: After the child is installed in the child safety seat, the seat can be rotated to the appropriate position by inputting instructions through the operation module 11 on the base group 1, voice or APP.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for part or all of the technical features. These modifications or substitutions do not change the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
