Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0039] Example 1

[0040] This embodiment provides an electric rotating mechanism for a car seat, such as... Figure 1-2 As shown, it includes:

[0041] Rotate the lower plate 1 to connect to the car body;

[0042] The upper rotating plate 2 is rotatably connected to the lower rotating plate 1 and is used to connect to the car seat body 7, which can drive the car seat body 7 to rotate.

[0043] The electric drive component 3 is used to drive the rotating upper plate 2 to rotate, and can be electrically adjusted and locked at any position.

[0044] In this embodiment, the lower rotating plate 1 is fixedly connected to the vehicle body by bolts, forming the fixed part of the rotating structure. The upper rotating plate 2 is connected to the mounting base of the vehicle seat body 7 by bolts, forming the rotating part of the rotating structure. The rotation is driven by the electric drive component 3, realizing the electric adjustment of the vehicle seat rotation, replacing the mechanical rotating structure that requires manual adjustment. This not only saves effort but also provides more rotation locking angles. Furthermore, the electrification of the electric drive component 3 can be combined with a smart cockpit to realize various intelligent functions, such as the vehicle seat automatically rotating to welcome the occupants when the door is opened.

A first gap is formed between the rotating upper plate 2 and the fixed cover 4, and a second gap is formed between the rotating upper plate 2 and the rotating lower plate 1.

[0047] Multiple upper row ball bearings 5 ​​are arranged in a ring in the first gap, with the upper part rollingly connected to the fixed cover 4 and the lower part rollingly connected to the rotating upper plate 2.

[0048] Multiple lower row balls 6 are arranged in a ring in the second gap, with the upper part connected to the upper rotating plate 2 and the lower part connected to the lower rotating plate 1 in a rolling connection.

[0049] In this embodiment, the fixed cover 4 is bolted to the rotating lower plate 1, clamping the upper row of ball bearings 5, the lower row of ball bearings 6, and the rotating upper plate 2, thus realizing the rotational connection of the rotating upper plate 2. The fixed cover 4 also provides installation space for the electric drive component 3.

[0050] Optionally, multiple lower row balls 6 are arranged in double rows on the inner and outer rings of the second gap.
