Technical Field

[0001] The present application relates to the technical field of safety seats, and in particular to a lightweight rotating structure and a safety seat. Background Art

[0002] A car safety seat is a seat that is fastened to the seat of a car. It is an automobile accessory device that has a restraining and protective function. The commonly referred to safety seats, child safety seats, child car safety seats and car protection seats, etc., all refer to this safety seat, which is only for children to sit in and can restrain children to ensure their safety in the event of a car accident.

[0003] However, existing safety seats have the following defects: in order to ensure the strength of the rotating structure, safety seats on the market usually adopt a more complex design or a design with more materials, but this can easily lead to increased assembly difficulty, reduced assembly efficiency, and an increase in the overall weight of the safety seat. Summary of the invention

[0004] One object of the present application is to provide a lightweight rotating structure and a safety seat with light weight and high structural strength.

[0005] To achieve the above objectives, the technical solution adopted in the present application is: a lightweight rotating structure, comprising a base and a rotating component, the rotating component being rotatably arranged on the base, the rotating component being provided with at least one first limiting portion, and the base being provided with at least one second limiting portion, the first limiting portion being suitable for passing through the second limiting portion along the circumference of the rotating component, and the first limiting portion being suitable for cooperating and abutting with the second limiting portion to limit the rotating component from being away from the base.

[0006] In some embodiments, the rotating component is provided with a plurality of the first limiting portions along the circumference, and / or the base is provided with a plurality of the second limiting portions along the circumference of the rotating component.

[0007] In some embodiments, when the number of the first limiting portions and the number of the second limiting portions are both plural, at least one of the second limiting portions is located on the front side of the base, at least one of the second limiting portions is located on the rear side of the base, at least one of the first limiting portions is suitable for cooperating with the second limiting portion located on the front side of the base, and at least one of the second limiting portions is suitable for cooperating with the second limiting portion located on the rear side of the base.

[0008] In some embodiments, the second limiting portion is bent and extended along the circumference of the rotating component, and is suitable for line contact or surface contact with the first limiting portion.

[0009] In some embodiments, a contact distance between the first limiting portion and the second limiting portion is not greater than a relative maximum movable amount between the rotating assembly and the base.

[0010] In some embodiments, the first limiting portion is bent and extended along the circumference of the rotating component; the first limiting portion and the second limiting portion are suitable for biting and abutting along the circumference of the rotating component; and the second limiting portion is suitable for biting and abutting with the first limiting portion from above the first limiting portion.

[0011] In some embodiments, the rotating assembly includes a rotating disk and a slide rail fixing plate, the slide rail fixing plate is fixedly disposed on the rotating disk, and the first limiting portion is formed by bending a portion of an edge of the slide rail fixing plate.

[0012] In some embodiments, a reinforcing plate is provided on the slide rail fixing plate, and the reinforcing plate is located on the side of the slide rail fixing plate away from the first limiting portion, and the reinforcing plate is suitable for limiting the slide rail fixing plate at the first limiting portion from deforming toward the reinforcing plate.

[0013] In some embodiments, at least one side of the reinforcing plate is bent away from the slide rail fixing plate to form a reinforcing side.

[0014] A safety seat comprises any of the above-mentioned lightweight rotating structures.

[0015] Compared with the prior art, the beneficial effects of the present application are as follows: the lightweight rotating structure and the safety seat of the present application can assist in improving the connection stability between the rotating assembly and the base without affecting the rotation of the rotating assembly by setting a first limit portion on the rotating assembly and a second limit portion on the base. When the rotating assembly rotates relative to the base to a preset matching position of the first limit portion and the second limit portion, the first limit portion and the second limit portion can reinforce the connection strength between the rotating assembly and the base through contact matching, thereby reducing the probability of the rotating assembly being separated from the base. Since only the first limit portion and the second limit portion need to be arranged, compared with the rotating structure of a traditional safety seat, the rotating structure of the present application is less complex, which can effectively reduce the difficulty of product production and processing and assembly difficulty and reduce the overall weight.

[0026] The present application is further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 5As shown, the present application provides a lightweight rotating structure, including a base 1 and a rotating assembly 2, the base 1 is suitable for being connected to an interior structure of a vehicle, the rotating assembly 2 is suitable for installing a seat, the rotating assembly 2 is rotatably arranged on the base 1, at least one first limiting portion 2221 is arranged on the rotating assembly 2, and at least one second limiting portion 11 is arranged on the base 1, the first limiting portion 2221 is suitable for passing through the second limiting portion 11 in a circumferential direction of the rotating assembly 2, and the first limiting portion 2221 is suitable for cooperating and abutting with the second limiting portion 11 to limit the rotating assembly 2 from being away from the base 1.

[0028] During the rotation of the rotating component 2 relative to the base 1, the first limit portion 2221 can rotate with the rotating component 2. In this state, the first limit portion 2221 can smoothly pass through the second limit portion 11. When the rotating component 2 stops and the first limit portion 2221 is located at the first limit portion 2221, the first limit portion 2221 and the second limit portion 11 can cooperate and abut according to the state change between the rotating component 2 and the base 1. In the present application, when the rotating component 2 moves away from the base 1 under the action of external force, the first limit portion 2221 and the second limit portion 11 can cooperate and abut, thereby helping the connection structure between the rotating component 2 and the base 1 to limit the force it is subjected to within the load-bearing range, strengthen the connection between the rotating component 2 and the base 1, protect the connection structure between the rotating component 2 and the base 1, and reduce the probability of the rotating component 2 detaching from the base 1.

[0029] In some embodiments, the rotating assembly 2 is provided with a plurality of first limiting portions 2221 along the circumferential direction, so that the rotating assembly 2 can be reinforced by the cooperation of the first limiting portions 2221 and the second limiting portions 11 when it rotates 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 along the circumference of the rotating component 2, so that the rotating component 2 can be reinforced by the cooperation of the first limiting portion 2221 and the second limiting portion 11 when it rotates 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 along the circumference of the rotating component 2, at least one second limiting portion 11 is located on the front side of the base 1, and at least one second limiting portion 11 is located on the rear side of the base 1, and a plurality of first limiting portions 2221 are provided on the rotating component 2, at least one first limiting portion 2221 is suitable for cooperating with the second limiting portion 11 located on the front side of the base 1, and at least one second limiting portion 11 is suitable for cooperating 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 present application is usually arranged on the vehicle seat, the front side of the base 1 corresponds to the front side of the vehicle seat, and the rear side of the base 1 corresponds to the rear side of the vehicle seat. When the rotating component 2 is rotated to the point where the front and rear sides of the seat installed on the rotating component 2 correspond to or are opposite to the front and rear sides of the vehicle seat, the first limiting portion 2221 on the rotating component 2 can cooperate with the second limiting portion 11 at the corresponding position, thereby improving the connection strength and connection stability between the rotating component 2 and the base 1. In this way, the forces acting during the acceleration and braking of the vehicle can be overcome in a targeted manner, reducing the probability of damage to the connection structure between the rotating component 2 and the base 1.

[0033] In some embodiments, the first limit portion 2221 is bent and extended along the circumference of the rotating component 2, so that the first limit portion 2221 has sufficient length and area to facilitate contact and cooperation with the second limit portion 11, thereby reducing the probability of the first limit portion 2221 and the second limit portion 11 slipping off each other.

[0034] In some embodiments, the first limit portion 2221 and the second limit portion 11 are suitable for circumferential engagement and abutment along the rotating component 2, which can further enhance the matching stability between the first limit portion 2221 and the second limit portion 11 and reduce the probability of the first limit portion 2221 and the second limit portion 11 slipping off each other.

[0035] In some embodiments, at least a portion of the second limiting portion 11 is suitable for engaging with the first limiting portion 2221 from above. In the present application, the connection between the rotating disk 21 and the base 1 is an up and down rotating connection, and the second limiting portion 11 is a connection in which the first limiting portion 2221 is snapped on from above, which can effectively improve the connection strength between the second limiting portion 11 and the first limiting portion 2221. Before the first limiting portion 2221 or the second limiting portion 11 undergoes a significant deformation until they are completely separated from each other, the first limiting portion 2221 or the second limiting portion 11 can maintain the structural reinforcement between the rotating disk 21 and the base 1.

[0036] like Figure 2 In the illustrated embodiment, the second limiting portion 11 located on the rear side of the base 1 extends circumferentially along the rotating component 2 and is suitable for line contact or surface contact with the first limiting portion 2221, so that the first limiting portion 2221 and the second limiting portion 11 have sufficient contact area, which can effectively improve the connection strength.

[0037] In some embodiments, the second limiting portion 11 may be a hook structure, which can make point contact, line contact, or surface contact with the first limiting portion 2221, making processing and installation simpler.

[0038] like Figure 2In the illustrated embodiment, when a plurality of second limiting portions 11 are provided on the base 1, second limiting portions 11 of different structural types can be selected to facilitate 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 limit portion 2221 and the second limit portion 11 is no greater than the relative maximum activity between the rotating component 2 and the base 1, ensuring that the first limit portion 2221 and the second limit portion 11 can engage and abut before the connection structure between the rotating component 2 and the base 1 reaches the load limit and is damaged, thereby dispersing and bearing the force transmitted from the rotating component 2 to the base 1, and protecting the connection structure between the rotating component 2 and the base 1 from damage.

[0040] like Figures 1 to 2 In the illustrated embodiment, the rotating assembly 2 includes a rotating disk 21 and at least one slide rail fixing plate 22. The rotating disk 21 is rotatably disposed on the base 1, and the slide rail fixing plate 22 is fixedly disposed on the rotating disk 21. The slide rail fixing plates 22 of the present application are set to two in number according to actual needs. The two slide rail fixing plates 22 are symmetrically disposed on both sides of the rotation center of the rotating disk 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 a portion of the edge of the slide rail fixing plate 22 , and the first limiting portion 2221 is formed by processing a portion of the edge of the slide rail fixing plate 22 into an arc-shaped flange.

[0042] like Figure 2 and 3 In the illustrated embodiment, the slide rail fixing plate 22 includes a connecting plate 221 and a bottom plate 222. The connecting plate 221 is connected to the seat, and the bottom plate 222 is connected to the rotating disk 21. The two ends of the bottom plate 222 are arranged near the edge of the rotating disk 21, and the two ends of the bottom plate 222 are bent to form a first limiting portion 2221. In the present application, the two 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 front and rear position adjustment of the passenger. Therefore, when the rotating disk 21 stops and the front and rear direction of the seat is corrected to be parallel to the front and rear direction of the base 1, the first limiting portions 2221 at both ends of the bottom plate 222 can be respectively matched with the second limiting portions 11 on the front and rear sides of the base 1 to specifically overcome the force exerted on the rotating disk 21 and the base 1 due to the inertia of the seat when the car accelerates and brakes.

[0043] like Figures 3 to 5In the shown embodiment, a reinforcing plate 3 is provided on the slide rail fixing plate 22, and the reinforcing plate 3 is located on the side of the slide rail fixing plate 22 away from the first limiting portion 2221. The reinforcing plate 3 is suitable for limiting the deformation of the slide rail fixing plate 22 at the first limiting portion 2221 toward the reinforcing plate 3. In the present application, the cross-section of the first limiting portion 2221 is an L-shaped structure. When the first limiting portion 2221 is subjected to an external force, the connection between the first limiting portion 2221 and the slide rail fixing plate 22 usually bends and deforms before the first limiting portion 2221 itself. The reinforcing plate 3 can reduce the occurrence of this phenomenon, thereby avoiding the probability of failure of the reinforcement effect 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 toward the side away from the slide rail fixing plate 22 to form a reinforcing edge 31. The reinforcing edge 31 can enhance the structural strength of the reinforcing plate 3, so that the reinforcing plate 3 can have a higher structural strength to assist the slide rail fixing plate 22 at the first limiting portion 2221 to reduce or even prevent deformation.

[0045] like Figure 2 In the illustrated embodiment, reinforcing edges 31 are provided on both sides of the reinforcing plate 3 close to the first limiting portion 2221 , which can effectively improve the structural strength of the reinforcing plate 3 and the supporting performance of the reinforcing plate 3 on the slide rail fixing plate 22 .

[0046] The present 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 present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
