[0002] For car seats, in the existing design, except for the braking mechanism which is modular, all other parts need to be developed separately for each car model. Therefore, how to make the design as modular as possible, except for the part connected to the car body, and improve the problems of high mold costs and long development cycles has become a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] A universal assembly for a seat turntable includes, from top to bottom, a moving plate assembly, a slide rail, and a fixed plate assembly, and further includes a braking mechanism connected to the moving plate assembly and the fixed plate assembly; The slide is a circular slide consisting of slide tubes and steel ball assemblies arranged and connected alternately, and is placed on the fixed plate assembly; It also includes a pretensioning assembly consisting of a follower plate, a pretensioning bar, and a pressure plate; and the pretensioning bar, follower plate, and pressure plate all form mutually compatible ring structures; The follower disk, which is fixedly connected to the moving disk assembly, is slidably connected to the slide rail; The inner edge of the pressure plate and the outer edge of the follower plate are fixedly connected to the fixed plate assembly, and a pre-tightening strip is provided at the connection point; the pre-tightening strip and the steel ball are located on the same vertical axis; The moving plate assembly and the fixed plate assembly are connected by clamp connectors.

[0005] Preferably, the pretensioning strip is a ring structure composed of multiple pretensioning strips with gaps.

[0006] Preferably, the pretensioning strip has a plurality of radial grooves arranged sequentially from top to bottom along the direction from the outer ring to the inner ring; The top radial groove has a horizontal structure; the inner edge of the pressure plate is inserted into the top radial groove. The remaining radial grooves are either enlarged from the inside out or horizontal.

[0007] Preferably, the follower disk has a hat-shaped structure with a convex center and flat edges, and a through hole for placing the braking mechanism is provided in the center.

[0008] Preferably, the follower disk is composed of a raised disk and a first horizontal disk fixedly connected together; Among them, the inner side of the pretension bar and the side of the raised disc are connected by a gap; The pretension bar is placed on the first horizontal plate.

[0009] Preferably, the pressure plate has a disc-shaped structure with a concave center and flat edges, and a through hole for placing the braking mechanism is provided in the center.

[0010] Preferably, the moving plate assembly includes a moving plate and a moving plate support connected to the moving plate; The moving disc support has a disc-shaped structure with a concave center and flat edges; The bottom surface of the moving plate support is fixedly connected to the following plate; the gap between the moving plate support and the pressure plate is set.

Detailed Implementation

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Example 1 To facilitate understanding of the technical solution in this embodiment, the purpose of this embodiment is to improve the existing system where turntables need to be specially customized for different cars. Although the principles of different turntables are similar, they still lack universality and are difficult to modularize.

[0020] Therefore, this embodiment proposes a universal component suitable for seat turntables, such as... Figure 1-4 As shown, the assembly includes, from top to bottom, the following components connected in sequence: a moving disc assembly 1, a slide rail 5, and a fixed disc assembly 2. It also includes a braking mechanism 4 connected to the moving disc assembly 1 and the fixed disc assembly 2. The output end of the braking mechanism 4 is connected to the moving disc assembly 1 via a transmission connection. The main body of the braking mechanism 4 is fixedly connected to the fixed disc assembly 2. The fixed disc assembly 2 is fixed to the vehicle body and rotates the moving disc 11 via the rotation of the braking mechanism 4. A motor is connected to the braking mechanism 4 via a toothed connection, and when the motor rotates, it can drive the output end of the brake to rotate. In this embodiment, the slide 5 is a circular slide 5 composed of slide tube 53 and steel ball assembly arranged alternately and connected, and is placed on the fixed plate assembly 2; It also includes a pretensioning assembly 3 consisting of a follower plate 33, a pretensioning bar 32, and a pressure plate 31; and the pretensioning bar 32, the follower plate 33, and the pressure plate 31 all form mutually compatible ring structures; in actual assembly, the pretensioning bar 32 needs to be pre-pressed before it is laid out. The follower disk 33, which is fixedly connected to the moving disk assembly 1, is slidably connected to the slide rail 5; The inner edge of the pressure plate 31, which is fixedly connected to the fixed plate assembly 2, and the outer edge of the follower plate 33 are engaged, and a pre-tightening strip 32 is provided at the engagement point; the pre-tightening strip 32 and the steel ball 51 are located on the same vertical axis; the moving plate assembly 1 and the fixed plate assembly 2 are connected by a clamp connector.

[0021] It should also be noted that in actual application, the outer edge of the follower plate 33 and the pretensioning strip 32 slide relative to each other when the turntable is working. Compared with the traditional setting of placing the elastic element at the bottom of the traditional fixed plate assembly 2, at the top of the moving plate 11, or between the moving plate 11 and the fixed plate assembly 2, and configured for both seat unloaded and loaded positions, the function of the pretensioning strip 32 is better. In this embodiment, the pretensioning strip 32 is always pressed by the pressure plate 31 during the rotation of the follower plate 33, which can continuously and evenly compensate for axial clearance. At the same time, there is relative sliding between the pretensioning strip 32 and the follower plate 33. This layout effectively solves the problem of axial movement without affecting the normal rotation of the moving plate assembly 1. Furthermore, in this embodiment, the structure is set independently: the pressure plate 31 and the pretensioning strip 32 form a self-contained system and do not interfere with other functions of the moving plate 11, such as transmission and locking, and the arrangement is flexible. Easy maintenance: After the pretensioner 32 wears out, only the pressure plate 31 needs to be disassembled, without disassembling the moving plate 11. Controllable friction: Friction only occurs between the follower plate 33 and the slide 5. The area is small and predictable, making it easy to control the resistance through material selection.

[0022] Specifically: Regarding slide 5: The ball assembly includes a ball 51 and a shaped retainer 52; The steel ball 51 is connected to the irregularly shaped retainer 52 and the slide tube 53. Specifically, the two ends of the irregularly shaped retainer 52 are fixedly connected to the adjacent slide tube 53. The steel ball 51 cuts into the irregularly shaped retainer 52 and rolls inside the irregularly shaped retainer 52. The irregularly shaped retainer 52 and the fixed plate assembly 2 have no direct contact. During assembly, the steel ball 51 and the irregularly shaped retainer 52 are placed separately on the slide 5, followed by the follower plate 33, and finally the pressure plate 31. In this embodiment, the slide 5 is set on the fixed plate assembly 2 and the irregularly shaped retainer 52 is used, which greatly reduces the vibration and abnormal noise caused by the close distance between the slide 5 and the fixed plate assembly 2.

[0023] Regarding pretensioner strip 32: The pretension bar 32 is a ring structure composed of multiple pretension bars 32 with gaps; the optimal setting is a total of 4 pretension bars 32; the gap between adjacent pretension bars 32 is a virtual quadrangular prism structure that matches the pressure plate 31; by using a multi-segment pretension bar 32 and a slide 5 with steel balls 51, the problem of loose steel balls 51 and abnormal noise caused by changes in the fit dimensions due to metal fatigue after the assembly is under stress is solved.

[0024] The pretensioning bar 32 has several radial grooves arranged sequentially from top to bottom along the direction from the outer ring to the inner ring. The top radial groove has a horizontal structure; the inner edge of the pressure plate 31 is inserted into the top radial groove. The remaining radial grooves are either enlarged from the inside out or horizontal.

[0025] Furthermore, it should be noted that the top surface width of the pretensioner strip 32 is selected according to the actual material, and the top surface width of the pretensioner strip 32 is smaller than the bottom surface width of the pretensioner strip 32.

[0026] For follower disk 33: The follower disk 33 has a hat-shaped structure with a convex center and flat edges, and a through hole for placing the braking mechanism 4 is provided in the center.

[0027] The follower disk 33 is composed of a raised disk and a first horizontal disk fixedly connected together; Among them, the inner side of the pretension bar 32 and the side of the raised disc are connected by a gap; Pretension bar 32 is placed on the first horizontal plate.

[0028] For pressure plate 31: The pressure plate 31 has a disc-shaped structure with a concave center and flat edges, and a through hole for placing the braking mechanism 4 is provided in the center. The inner edge of the pressure plate 31 has a radial arc-shaped protrusion, which serves as an isolation and limiting member for the sub-pretensioning bar 32; and there is a notch at the connection between the arc-shaped protrusion and the inner edge of the pressure plate 31; in practice, the optimal setting is that the sub-pretensioning bar 32 needs to cover the notch when it is assembled to ensure the optimal realization of the function of the pretensioning bar 32.

[0029] The moving disk assembly 1 includes a moving disk 11 and a moving disk support 12 connected to the moving disk 11; The moving disc support 12 has a disc-shaped structure with a concave center and flat edges; The bottom surface of the moving plate support 12 is fixedly connected to the following plate 33; the gap between the moving plate support 12 and the pressure plate 31 is set.

[0030] The surface of the plate assembly 2 is provided with an annular groove, the slide 5 is placed in the annular groove, and the steel ball 51 rolls in the annular groove. The gap between the slide tube 53 and the annular groove is set.

[0031] It should be noted that in practical applications, this embodiment can be set for adjusting the direction of the car seat and the operation of the braking mechanism 4 can be set to achieve adjustment and locking at any angle. It can be set to a 90° welcome function and a 180° rear turn function, and can rotate freely within the range of 0~360° to provide space for in-vehicle leisure and entertainment. Seat adjustment: When the motor rotates, the output end of the driving brake mechanism 4 rotates, which drives the moving plate 11 to rotate. The seat on the moving plate 11 moves accordingly. At the same time, the steel ball 51 rotates in the annular groove to form a sliding support, which can ensure smooth rotation and realize the seat direction adjustment function. The seat can be rotated clockwise or counterclockwise by the motor driving forward or in reverse.

[0032] In summary, this embodiment adopts a modular design to reduce high mold costs and development cycles. By quickly replacing the moving plate support 12, it can be adapted to seats of different heights. By quickly replacing the quick-change connecting plate and reinforcing crossbeam used for connecting the fixed plate assembly 2 and the vehicle, it can achieve the connection of different vehicle chassis or slide rails without the need to customize other parts, as long as the turntable model and size are suitable.

[0033] In this embodiment, the slide rail 5 is arranged on the fixed plate assembly 2. Because the fixed plate assembly 2 has a large sheet metal thickness and a reinforced crossbeam welded around it, it can ensure that the dimensions of the slide rail 5 and the annular groove have minimal deformation after being subjected to force, ensuring that the key dimension chain of the assembly does not change, thus greatly reducing the strength requirements of other sheet metal. This embodiment can reduce weight by 20% compared to conventional structures on the market. Moreover, compared to traditional equipment, 70% of the molds do not need to be redeveloped for different vehicle models during production. While reducing product cost and weight, it also improves product performance reliability and application range.

[0034] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
