Description

Technical Field

[0001] This utility model belongs to the field of ceiling fan light technology, specifically, it relates to a rotating structure of a ceiling fan. Background Technology

[0002] Existing ceiling fans generally consist of a hanging rod, with a drive assembly mounted at the bottom of the rod. The drive assembly includes a motor body, a rotating housing mounted outside the motor body, and fan blades mounted on the housing. While this conventional structure is relatively simple, in practical use, the rotating parts are relatively large, resulting in slow start-up, high energy consumption, and significant noise. On the other hand, ceiling fans combined with lighting fixtures, such as ceiling fan lights, have also appeared on the market. These lights are installed below the rotating housing of the ceiling fan, fulfilling both airflow and lighting functions.

[0003] Chinese utility model patent CN221921396U discloses a rotating structure for a ceiling fan light, including a base frame, a hanging rod fixedly installed on the base frame, and a rotating disk body rotatably installed between the base frame and the hanging rod. This reduces the proportion of rotating parts in the overall ceiling fan structure. The base frame rod on the base frame is equipped with a stator winding, and an annular outer rotor magnet is set in the first housing of the rotating disk body. The rotating disk body and the base frame are rotatably mounted through a bearing assembly. The stator winding and the outer rotor magnet form a motor structure. During operation, the rotational gap formed between the rotating disk body and the base frame greatly reduces the friction coefficient of the rotating parts of the ceiling fan light, resulting in faster start-up, more stable rotation, and reduced noise.

[0004] While the aforementioned existing technology can significantly reduce the friction coefficient of the rotating parts of the ceiling fan light by using the rotational force generated by the external rotor magnet and the stator winding, resulting in faster start-up, more stable rotation, and reduced noise, it requires removing the entire ceiling fan light from the ceiling for inspection or replacement when the external rotor magnet and the stator winding are damaged. This makes the inspection and replacement of the ceiling fan light very troublesome. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when the outer rotor magnet and stator winding are damaged, the entire ceiling fan light needs to be removed from the ceiling for inspection or replacement, which makes the inspection and replacement of the ceiling fan light very troublesome, this utility model adopts the following technical solution.

[0007] A rotating structure for a ceiling fan includes a connecting rod, a connecting plate fixedly connected to the bottom of the connecting rod, a rotating ring rotatably connected to the bottom of the connecting plate, a connecting ring rotatably connected to the bottom of the rotating ring, a lighting body detachably connected to the bottom of the connecting ring, multiple rotating fan blades fixedly connected to the outer wall of the rotating ring, a disassembly assembly installed on the lighting body, and a rotating assembly installed at the upper end of the lighting body, the rotating assembly driving the rotating ring and the rotating fan blades to rotate.

[0008] Preferably, the rotating assembly includes a drive motor, a drive gear, and an internal gear ring. The internal gear ring is fixedly connected to the inner wall of the rotating ring. A mounting ring is detachably connected to the upper end of the lighting body, which is located inside the rotating ring.

The rotating end of the drive motor is detachably connected to the drive gear, which meshes with the internal gear ring.

[0009] Preferably, the disassembly and assembly assembly includes a sliding groove, a sliding plate, a connecting protrusion, a fixing bolt, a return spring, a plug-in post, and a fixing protrusion. Sliding grooves are provided on both sides of the upper end of the lighting body. A sliding plate is slidably connected inside the sliding grooves. A connecting protrusion is fixedly connected to the upper end of the sliding plate near the outside of the lighting body. A fixing bolt is threadedly connected to the upper end of the connecting protrusion. The threaded end of the fixing bolt is detachably connected to the upper end of the lighting body. A fixing protrusion is fixedly connected to the end of the sliding plate near the center. Holes are provided on both sides of the inner wall of the connecting ring. A plug-in post, inserted into the hole in the inner wall of the connecting ring, is fixedly connected to the opposite side of the two fixing protrusions. A return spring is fixedly connected to the outer wall of the opposite side of the two fixing protrusions.

[0010] Preferably, a connecting conduit is fixedly connected to the upper center of the lighting body, and a plug-in cylinder communicating with the connecting rod is fixedly connected to the bottom of the connecting plate.

[0012] Preferably, the positioning component includes a limiting groove and a limiting protrusion, the inner wall of the insertion cylinder is provided with a limiting groove, and the outer wall of the connecting tube is fixedly connected with a limiting protrusion.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The drive motor in the rotating assembly rotates, driving the drive gear to mesh with the internal gear ring, thus causing the rotating ring to rotate. This causes multiple rotating fan blades to rotate, generating downward airflow. During maintenance and replacement, the lighting unit can be disassembled, and the drive motor and lighting unit can be disassembled together for maintenance or replacement. During installation, the lighting unit is connected to the bottom of the connecting ring, and then the drive gear meshes with the internal gear ring.

[0015] 2. By loosening the fixing bolts on both sides of the disassembly assembly and simultaneously pushing the sliding plate inward, the plug can be dislodged from the inner wall of the connecting ring, allowing the lighting fixture to be removed. During installation, push the sliding plates inward simultaneously to insert the fixing protrusions on both sides into the inner wall of the connecting ring. Loosen the sliding plates on both sides, and the return force of the return springs on both sides will allow the plug to be inserted into the inner wall of the connecting ring, thus completing the installation. This makes installation and disassembly more convenient.

[0016] 3. By inserting the limiting protrusion and limiting groove in the positioning component, the insertion post can be aligned with the hole on the inner wall of the connecting ring, and the power cord can be stored inside the connecting tube and the limiting groove.

In this embodiment, the rotation of the rotating ring 102 and the rotating fan blades 103 generates downward wind force, and the lighting lamp body 200 generates a light source to achieve the lighting effect.

[0028] like Figure 2As shown, this is a schematic diagram of the rotating component structure in this embodiment. An internal gear ring 106 is fixedly connected to the inner wall of the rotating ring 102. A mounting ring 204 is detachably connected to the upper end of the lighting body 200, located inside the rotating ring 102.
