[0002] Planar bearings are a common mechanical component used for support and friction reduction. Hinges, on the other hand, are used to connect two objects and allow them to rotate relative to each other. The teardrop-shaped, easy-to-weld hinge may have the following design features: Teardrop design: This design may use one or more teardrop-shaped curves to replace the traditional straight line shape, making the hinge more beautiful and unique; Easy weldability: The hinge design may use easy-to-weld materials and structures to make the welding process easier to implement during the manufacturing process; Planar bearing structure: The hinge may integrate a plane bearing to reduce friction and wear during rotation and increase service life; Strength and stability: The design may take into account the forces and pressures that the hinge needs to withstand during use to ensure that it has sufficient strength and stability.

[0003] For example, the announcement number CN220890756U is a side support plate structure and a water drop hinge for a water drop hinge. The existing device side support plate structure includes: a side support plate, a columnar shaft arranged on one side of the side support plate, and a first pull plate structure and a top plate structure arranged on the other side of the side support plate. The upper surface of the side support plate is a plane for supporting the flexible screen; the columnar shaft is used to be clamped on the rotating frame; the first pull plate structure is used to cooperate with the second pull plate structure arranged on the middle frame to pull the side support plate toward the rotating frame when the rotating frame rotates relative to the middle frame; the top plate structure is used to contact the lower surface of the middle support plate when the rotating frame is flat with the middle frame.

At the same time, multiple welding positions are provided, so that the welding can be made more stable, and the two water drop half rings are not easy to separate from the upper ring and the lower ring.

[0024] Specifically, the two welding holes 12 are staggered with the two positioning holes 11. The above design can improve the connection strength: the staggered distribution can increase the contact area of ​​the connection point, thereby enhancing the strength and stability of the welding, which can provide a better connection effect under stress loading and reduce material fatigue; improve accuracy and repeatability: by realizing the staggered distribution, the accuracy of the welding position and relative position can be better controlled, which helps to reduce the deviation and error in the welding process and improve the consistency and repeatability of welding; reduce stress concentration: through the staggered distribution, the welding stress can be more evenly distributed in the area around the connection point, reducing the generation of stress concentration, which helps to reduce the stress concentration problem in the welding process and improve the life and reliability of welding; improve product quality: the staggered distribution can reduce the residual stress and deformation in the welding process, avoid causing quality defects such as cracks and deformation, which helps to improve the surface quality and overall performance of the product.

[0025] Specifically, the bearing assembly includes a mounting groove 2 opened inside the lower ring 1, a plurality of evenly distributed limit rods 3 are fixedly connected inside the mounting groove 2, a plurality of evenly distributed rollers 4 are arranged inside the mounting groove 2, and the plurality of rollers 4 are all in contact with the limit rods 3, a fixing ring 5 is fixedly connected to the outer side of the lower ring 1, a limit ring 6 is rotatably connected to the outer side of the lower ring 1, a ring groove 7 is opened inside the limit ring 6, and an upper ring 8 is fixedly connected to the inner side of the limit ring 6.
