[0026] The present application will be further described below in conjunction with the drawings:

[0027] As shown in FIGS. 1-5, the present application provides a lightweight rotating structure, which comprises a base 1 and a rotating assembly 2, the base 1 is adapted to be connected with the structure inside the vehicle, the rotating assembly 2 is adapted to mount a seat thereon, the rotating assembly 2 is rotatably arranged on the base 1, the rotating assembly 2 is provided with at least one first limiting portion 2221, the base 1 is provided with at least one second limiting portion 11, the first limiting portion 2221 is adapted to pass through the second limiting portion 11 in the circumferential direction of the rotating assembly 2, and the first limiting portion 2221 is adapted to abut against the second limiting portion 11 to limit the rotating assembly 2 from moving away from the base 1.

[0028] During the rotation of the rotating assembly 2 relative to the base 1, the first limiting portion 2221 can rotate with the rotating assembly 2, and in this state, the first limiting portion 2221 can smoothly pass through the second limiting portion 11. When the rotating assembly 2 stops and the first limiting portion 2221 is located at the first limiting portion 2221, the first limiting portion 2221 and the second limiting portion 11 can abut against each other according to the state change between the rotating assembly 2 and the base 1. In the present application, when the rotating assembly 2 moves away from the base 1 under the action of an external force, the first limiting portion 2221 and the second limiting portion 11 can abut against each other, thereby helping to reinforce the connection between the rotating assembly 2 and the base 1, limiting the force acting on the connection structure between the rotating assembly 2 and the base 1 within a bearing range, strengthening the connection between the rotating assembly 2 and the base 1, protecting the connection structure between the rotating assembly 2 and the base 1, and reducing the probability of the rotating assembly 2 separating from the base 1.

[0029] In some embodiments, the rotating assembly 2 is provided with a plurality of first limiting portions 2221 in the circumferential direction, so that the rotating assembly 2 can be reinforced by the first limiting portion 2221 and the second limiting portion 11 when it is rotated to different positions relative to the base 1.

[0030] In some embodiments, the base 1 is provided with a plurality of second limiting portions 11 in the circumferential direction of the rotating assembly 2, so that the rotating assembly 2 can be reinforced by the first limiting portion 2221 and the second limiting portion 11 when it is rotated to different positions relative to the base 1.

[0031] In some embodiments, the base 1 is provided with a plurality of second limiting portions 11 in the circumferential direction of the rotating assembly 2, at least one second limiting portion 11 is located on the front side of the base 1, at least one second limiting portion 11 is located on the rear side of the base 1, the rotating assembly 2 is provided with a plurality of first limiting portions 2221, at least one first limiting portion 2221 is adapted to cooperate with the second limiting portion 11 located on the front side of the base 1, and at least one second limiting portion 11 is adapted to cooperate with the second limiting portion 11 located on the rear side of the base 1.

[0032] It can be understood that the base 1 of the application is generally arranged on the seat, the front side of the base 1 corresponds to the front side of the seat, and the rear side of the base 1 corresponds to the rear side of the seat. When the rotating assembly 2 is rotated to the front and rear sides of the seat installed on the rotating assembly 2 correspond to or are opposite to the front and rear sides of the seat, the first limiting portions 2221 on the rotating assembly 2 can all cooperate with the second limiting portions 11 at the corresponding positions, thereby improving the connection strength and stability between the rotating assembly 2 and the base 1. In this way, the acting force during acceleration and braking of the automobile can also be overcome in a targeted manner, and the probability of damage to the connection structure between the rotating assembly 2 and the base 1 is reduced.

[0033] In some embodiments, the first limiting portions 2221 extend circumferentially along the rotating assembly 2, so that the first limiting portions 2221 have sufficient length and area to facilitate contact and cooperation with the second limiting portions 11, thereby reducing the probability of mutual slippage of the first limiting portions 2221 and the second limiting portions 11.

[0034] In some embodiments, the first limiting portions 2221 and the second limiting portions 11 are adapted to engage and abut circumferentially along the rotating assembly 2, which can further improve the cooperation stability between the first limiting portions 2221 and the second limiting portions 11 and reduce the probability of mutual slippage of the first limiting portions 2221 and the second limiting portions 11.

[0035] In some embodiments, at least part of the second limiting portions 11 is adapted to engage the first limiting portions 2221 from above. In the application, the connection form of the rotating disc 21 and the base 1 is up-down rotary connection, and the second limiting portions 11 engage the first limiting portions 2221 from above, which can effectively improve the connection strength of the second limiting portions 11 and the first limiting portions 2221. Before the first limiting portions 2221 or the second limiting portions 11 are deformed to a large extent until they are completely separated from each other, the first limiting portions 2221 or the second limiting portions 11 can maintain the structural reinforcement between the rotating disc 21 and the base 1.

[0036] As shown in the embodiment of FIG. 2, the second limiting portions 11 located at the rear side of the base 1 extend circumferentially along the rotating assembly 2 and are adapted to make line contact or surface contact with the first limiting portions 2221, so that the first limiting portions 2221 and the second limiting portions 11 can have sufficient contact area, which can effectively improve the connection strength.

[0037] In some embodiments, the second limiting portions 11 can be a hook structure, which can make point contact, line contact or surface contact with the first limiting portions 2221, and is simpler to process and install.

[0038] In the embodiment shown in FIG. 2, when the plurality of second limiting portions 11 are arranged on the base 1, different types of second limiting portions 11 can be arranged to facilitate the structural design and space optimization between the base 1 and the rotating assembly 2, reduce structural interference, and reduce assembly difficulty.

[0039] In some embodiments, the contact distance between the first limiting portion 2221 and the second limiting portion 11 is not greater than the maximum relative movement amount between the rotating assembly 2 and the base 1, which ensures that the first limiting portion 2221 and the second limiting portion 11 can engage and abut before the connecting structure between the rotating assembly 2 and the base 1 reaches the load limit and is damaged, thereby dispersing and bearing the force transmitted from the rotating assembly 2 to the base 1, and protecting the connecting structure between the rotating assembly 2 and the base 1 from being damaged.

[0040] In the embodiments shown in FIGS. 1 and 2, the rotating assembly 2 includes a rotating disc 21 and at least one slide rail fixing plate 22, the rotating disc 21 is rotationally arranged on the base 1, and the slide rail fixing plate 22 is fixedly arranged on the rotating disc 21. According to actual needs, the number of slide rail fixing plates 22 in the present application is two, the two slide rail fixing plates 22 are symmetrically arranged on both sides of the rotation center of the rotating disc 21, and a seat can be installed between the two slide rail fixing plates 22.

[0041] In some embodiments, the first limiting portion 2221 is formed by bending part of the edge of the slide rail fixing plate 22, and the first limiting portion 2221 is formed by processing part of the edge of the slide rail fixing plate 22 into an arc-shaped flange.

[0042] In the embodiments shown in FIGS. 2 and 3, the slide rail fixing plate 22 includes a connecting plate 221 and a bottom plate 222, the connecting plate 221 is connected with the seat, the bottom plate 222 is connected with the rotating disc 21, both ends of the bottom plate 222 are arranged close to the edge of the rotating disc 21, both ends of the bottom plate 222 are bent to form the first limiting portion 2221, and in the present application, both ends of the bottom plate 222 are located in the sliding adjustment direction of the seat. In actual application, the sliding adjustment direction of the seat is the forward and backward position adjustment of the passenger, and therefore, when the rotating disc 21 stops and the forward and backward direction of the seat is aligned to be parallel to the forward and backward direction of the base 1, the first limiting portion 2221 at both ends of the bottom plate 222 can be respectively aligned and matched with the second limiting portion 11 on both sides of the base 1, so as to specifically overcome the force applied to the connecting structure between the rotating disc 21 and the base 1 due to the inertia of the seat when the vehicle accelerates or brakes.

[0043] In the embodiment shown in FIGS. 3-5, the reinforcing plate 3 is arranged on the slide rail fixing plate 22 and located on the side of the slide rail fixing plate 22 away from the first limiting portion 2221. The reinforcing plate 3 is adapted to limit the deformation of the slide rail fixing plate 22 at the first limiting portion 2221 to the side of the reinforcing plate 3. In this application, the cross section of the first limiting portion 2221 is in the shape of L. When the first limiting portion 2221 is subjected to external force, the connection between the first limiting portion 2221 and the slide rail fixing plate 22 usually bends first before the first limiting portion 2221 itself bends. The reinforcing plate 3 can reduce the occurrence of this phenomenon, thereby avoiding the probability of the reinforcing effect being invalid due to the deformation of the first limiting portion 2221.

[0044] In some embodiments, at least one side of the reinforcing plate 3 is bent to form a reinforcing side 31 away from the slide rail fixing plate 22. The reinforcing side 31 can improve the structural strength of the reinforcing plate 3, so that the reinforcing plate 3 can have higher structural strength to assist the slide rail fixing plate 22 at the first limiting portion 2221, thereby reducing or even eliminating the deformation.

[0045] In the embodiment shown in FIG. 2, the reinforcing plate 3 is provided with reinforcing sides 31 on both sides near the first limiting portion 2221, which can effectively improve the structural strength of the reinforcing plate 3 and improve the supporting performance of the reinforcing plate 3 on the slide rail fixing plate 22.

[0046] The application also provides a safety seat comprising the lightweight rotating structure of any of the above embodiments.

Those skilled in the art should understand that the application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the application. Without departing from the spirit and scope of the application, various changes and improvements can be made to the application, and these changes and improvements all fall within the scope of the claimed application.
