Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a turntable ball bearing structure. Background Technology

[0002] A car seat turntable is a turntable installed under the seat cushion in a car seat. The turntable is used to adjust and rotate the seat, allowing the seat to rotate 360°. Car seats with turntables are increasingly in demand in today's luxury cars or commercial vehicles. The ability to rotate and adjust the seat serves two purposes: firstly, it allows the seat to face guests, and secondly, it allows front-seat passengers to rotate to the rear seats for easier communication with rear passengers.

[0003] However, traditional car seat turntable structures usually use a direct contact method, meaning the turntable and the base are in direct contact. This structure is prone to severe wear and tear after prolonged use, which greatly affects the lifespan and smoothness of the turntable. Utility Model Content

[0004] The purpose of this invention is to provide a turntable ball bearing structure that solves the problem that the existing traditional car seat turntable structure usually adopts a direct contact method, that is, the turntable and the base are in direct contact. This structure is prone to severe wear after long-term use, which greatly affects the service life and smoothness of the turntable.

[0005] To achieve the above objectives, this utility model employs a turntable ball bearing structure, comprising a base shell, a turntable, an inner ring shell, an outer ring shell, a connecting disc, fasteners, a driving component, a driving gear, two driven gears, a gear ring, a first ball ring, a second ball ring, a third ball ring, and a fourth ball ring. The turntable is located above the base shell and has two turntable ball grooves. The first and third ball rings are both disposed within the base shell, while the second and fourth ball rings are respectively disposed within their corresponding turntable ball grooves. The inner ring shell and the outer ring shell... Each component is fixedly connected to the bottom shell and movably connected to the corresponding ball groove of the turntable. The connecting plate is located above the turntable. The fasteners are connected to the turntable and the connecting plate respectively. The gear ring is fixedly connected to the connecting plate and located below the connecting plate. The driving component is fixedly connected to the bottom shell and located below the bottom shell. The driving gear is connected to the driving component and located inside the gear ring, and the driving gear meshes with the gear ring. Both driven gears are rotatably mounted on the bottom shell and mesh with the gear ring.

[0006] The driving component includes a bracket and a drive motor. The bracket is fixedly connected to the bottom shell and located below the bottom shell. The drive motor is fixedly connected to the bracket and located below the bracket. The output end of the drive motor is connected to the drive gear.

[0007] The fastener includes multiple connecting bolts and multiple fixing nuts. The multiple connecting bolts are all fixedly connected to the turntable and are all located on the turntable. The multiple connecting bolts all movably pass through the connecting disc. Each fixing nut is respectively sleeved on the outside of the corresponding connecting bolt and respectively engages with the thread of the connecting bolt.

[0008] The turntable ball bearing structure also includes a protective shell, which is fixedly connected to the connecting disc and sleeved on the outside of the drive gear.

[0009] The turntable ball bearing structure also includes multiple positioning pins, all of which are fixedly connected to the turntable and are located above the turntable.

[0010] This utility model discloses a turntable ball bearing structure. The two ball bearing grooves of the turntable are movably connected to the outer ring housing and the inner ring housing, respectively. A ball ring is provided in the gap between the outer ring housing, the ball bearing grooves, and the bottom housing. Similarly, a ball ring is provided in the gap between the inner ring housing, the ball bearing grooves, and the bottom housing. In use, the drive unit below the bottom housing is activated. The drive unit controls the rotation of the drive gear. Since the drive gear meshes with the gear ring, the gear ring is driven to rotate. The ring is fixed on the connecting plate. Then, the connecting plate rotates and drives the turntable to rotate above the bottom shell. At the same time, the two ball grooves of the turntable slide against the inner ring shell and the outer ring shell respectively through the ball ring, realizing the rolling connection between the turntable and the bottom shell. In the above method, the ball ring includes a mounting ring and balls. By adopting the ball connection method, point and surface contact is made, reducing the contact area, reducing wear, making the turntable rotate more smoothly, and greatly affecting the service life and rotation smoothness of the turntable.
