Detailed Implementation

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0031] This utility model relates to a rotating connection assembly, including a base 100, a rotating motor 200, a first connecting member 300, and a second connecting member 400. This rotating connection assembly is mainly used in fans or fan lights. The following embodiments illustrate the application of the rotating connection assembly in a fan light.

[0032] like Figure 1 and Figure 2As shown, the first connector 300 is mounted on the base 100, and the first connector 300 is fixedly mounted relative to the base 100. The two can be fixed relative to each other by means of, but not limited to, gluing, welding, fastening, or screw locking. The first connector 300 has a first ball joint surface 310, which can be hemispherical or a smaller-than-a-sphere shape. The second connector 400 is coaxially mounted on the rotating shaft 210 of the rotating motor 200, and the rotating shaft 210 passes through the second connector 400. The second connector 400 and the rotating shaft 210 can rotate relative to each other. The second connector 400 has a second ball joint surface 410, which can be hemispherical or a smaller-than-a-sphere shape. The shapes of the first ball joint surface 310 and the second ball joint surface 410 are compatible, and they can fit together to form a spherical sliding connection. It is understood that the inner diameter of the first ball joint surface 310 can be set to be larger than the inner diameter of the second ball joint surface 410, and when the two are fitted together, the first ball joint surface 310 is located outside the second ball joint surface 410. In this embodiment, as shown... Figure 6 and Figure 7 As shown, the inner diameter of the second ball joint surface 410 is set to be larger than the inner diameter of the first ball joint surface 310, and when the two are fitted together, the second ball joint surface 410 is located outside the first ball joint surface 310. The rotating shaft 210 passes through the first connecting member 300, and the base 100 avoids the rotating shaft 210. The rotating shaft 210 can swing relative to the first connecting member 300 in a direction deviating from the central axis of the first connecting member 300. Figure 1 As shown, the second connecting member 400 can swing relative to the first connecting member 300 in a 360° directional swing around the central axis of the first connecting member 300. In actual use, a swing motor 700 is also installed on the base 100 of the fan light. The swing motor 700 is connected to the rotating motor 200, and the fan blades are installed on the rotating shaft 210 of the rotating motor 200. During operation, the rotating motor 200 drives the fan blades to rotate through the rotating shaft 210. When the rotating shaft 210 rotates, it rotates relative to the second connecting member 400, that is, the second connecting member 400 does not rotate around the axial direction with the rotating shaft 210. The swing motor 700 drives the rotating motor 200 to swing, which in turn drives the fan blades to swing through the rotating shaft 210, thereby changing the direction of airflow. At the same time, the second connecting member 400 swings relative to the first connecting member 300 with the rotating shaft 210, and the second ball joint surface 410 slides relative to the first ball joint surface 310. When the rotating motor 200 swings, the first connecting piece 300 serves as a support, limiting the second connecting piece 400 and the rotating shaft 210 from wobbling in the radial direction, thereby ensuring the stability of the fan blades during the swinging process. The overall structure is simple and easy to install.

[0033] In some embodiments of this utility model, such as Figure 3 , Figure 6 and Figure 7As shown, one of the first ball joint surface 310 and the second ball joint surface 410 has multiple grooves 500 arranged sequentially along the circumference. The grooves 500 reduce the contact area between the first ball joint surface 310 and the second ball joint surface 410, thereby reducing friction and making the relative sliding between them smoother, preventing noise caused by excessive friction. Furthermore, during assembly, a lubricant such as petroleum jelly is applied between the first ball joint surface 310 and the second ball joint surface 410 to further reduce friction. Each groove 500 can store a certain amount of lubricant, which replenishes the contact surface when the first ball joint surface 310 and the second ball joint surface 410 slide relative to each other. The grooves 500 effectively increase the filling amount between the first ball joint surface 310 and the second ball joint surface 410, reducing wear and extending the service life of the first connector 300 and the second connector 400.

[0034] Based on the above embodiments, in this embodiment, each groove 500 is formed on the first ball joint surface 310. The first connector 300 has a first end 320 and a second end 330. The first end 320 faces the second connector 400. In the illustrated direction, the rotating shaft 210 passes through the first connector 300 from top to bottom. The second connector 400 is located above the first connector 300. The first end 320 of the first connector 300 faces upward, and the second end 330 faces downward. The second end 330 is fixedly connected to the base 100. The groove 500 extends vertically up and down on the outer wall of the first connector 300. The upper end of the groove 500 extends upward to the first end 320, and the upper end of the groove 500 is open to form an open end 510. The lower end of the groove 500 extends downward towards the second end 330, but the lower end of the groove 500 does not penetrate to the second end 330, so that the lower end of the groove 500 forms a closed end 520. The second ball joint surface 410 closes or partially closes the groove 500 on one side of the first ball joint surface 310. When lubricating oil is filled between the first ball joint surface 310 and the second ball joint surface 410, the lubricating oil can flow into the groove 500 through the open end 510 and then stop at the closed end 520 of the groove 500. The groove 500 can be configured as a long strip-shaped groove structure with equal width everywhere. In this embodiment, the width of the groove 500 gradually decreases from the open end 510 to the closed end 520, forming a dovetail groove shape. The open end 510 of the groove 500 extends into the range of the second ball joint surface 410 along with the first end 320. The larger the open end 510 of the groove 500, the smaller the contact area between the first ball joint surface 310 and the second ball joint surface 410. The smaller the closed end of the groove 500, the longer the lubricating oil can be stored in the groove 500 and slowly released between the contact surfaces of the first ball joint surface 310 and the second ball joint surface 410.

[0035] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, a first through hole 340 is provided on the first connector 300. In the direction shown, the first through hole 340 extends through the upper and lower sides of the first connector 300. A second through hole 110 is provided on the base 100. After the first connector 300 is fixed to the base 100, the first through hole 340 and the second through hole 110 are coaxial and interconnected. A rotating shaft 210 passes through the first through hole 340 and the second through hole 110 in sequence. The rotating shaft 210 will not contact the first through hole 340 or the second through hole 110 during rotation and oscillation. A first ball joint surface 310 is provided on the circumferential outer wall of the first connector 300, and the first ball joint surface 310 is coaxially arranged with the first through hole 340. At this time, the second ball joint surface 410 is located outside the first ball joint surface 310.

[0036] In some embodiments of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, a bearing 600 is provided between the rotating shaft 210 and the second connecting member 400. The bearing 600 reduces the rotational friction between the second connecting member 400 and the rotating shaft 210. Specifically, a third through hole 420 and a fourth through hole 430 are coaxially formed on the second connecting member 400. The third through hole 420 and the fourth through hole 430 are distributed in a stepped hole pattern. A second ball joint surface 410 is provided on the inner wall of the third through hole 420. The minimum inner diameter of the third through hole 420 is smaller than the diameter of the fourth through hole 430. The bearing 600 is installed in the fourth through hole 430, and there can be an interference fit between the fourth through hole 430 and the bearing 600. The first ball joint surface 310 extends into the third through hole 420 and abuts against the second ball joint surface 410 to achieve a spherical sliding connection. The second ball joint surface 410 is spherical crown-shaped. This spherical crown shape is preferably smaller than a hemisphere. The inner diameter of the end of the third through hole 420 closest to the fourth through hole 430 is smaller than the inner diameter of the end of the third through hole 420 furthest from the fourth through hole 430. That is, the inner diameter of the upper end of the third through hole 420 is smaller than its lower end. The rotating shaft 210 passes through the third through hole 420 and the fourth through hole 430. With the cooperation of the bearing 600, the axial direction and the second connecting member 400 are relatively stationary in the radial and axial directions.
