Description

Technical Field

[0001] The utility model relates to the technical field of household electric fans, in particular to a rotating structure of a ceiling fan with a lamp. Background Art

[0002] Existing ceiling fan lights generally include a suspension rod, a driving device installed under the suspension rod, the driving device uses a motor, the rotating body of the fan is set on the outer rotor of the motor, and the rotating body is then installed with fan blades. Some ceiling fans also have lamps installed under the rotating body, which have both lighting and aesthetic effects. However, the rotating connection structure of the rotating body of ceiling fans currently on the market is not stable enough, such as Figure 6 As shown, the rotating body is only connected by a single bearing, and the force is not uniform, resulting in that the ceiling fan of this structure can only be made relatively small. It will also become loose and make abnormal noises after long-term use. In addition, it is not convenient to fix and install lamps under the rotating body. After the lamps are installed, the stability and durability of the structure are difficult to guarantee. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a rotating structure of a ceiling fan with a light, which has the characteristics of stable structure and low rotation noise.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A rotating structure of a ceiling fan with a light comprises a hanger, a bottom frame fixedly connected to the bottom of the hanger, and a rotating body rotatably arranged between the hanger and the bottom frame;

[0006] The base frame includes a connecting pin connected between the base frame and the hanger, and the upper and lower ends of the connecting pin are respectively tightly sleeved with a first bearing and a second bearing. The upper end of the rotating body cooperates with the outer ring of the first bearing, and the lower end of the rotating body cooperates with the outer ring of the second bearing, so that the rotating body forms a rotational relationship relative to the hanger and the base frame.

[0007] A stator assembly is installed outside the connecting pin, an outer rotor assembly rotatably matched with the stator assembly is installed inside the rotating body, and the outer rotor assembly and the stator assembly form a motor structure to drive the rotating body to rotate.

[0008] The rotating body includes an inner shell and a bottom shell fixedly installed below the inner shell. The outer rotor assembly is installed on the annular inner wall of the inner shell. The upper end of the inner shell is formed with a first annular step for abutting against the outer ring of the first bearing, and the lower end of the bottom shell is formed with a second annular step for abutting against the outer ring of the second bearing.

[0009] The base frame also includes a mounting chassis, the lower end of the connecting pin passes through the middle of the mounting chassis and is fixed, and a connecting thread for mounting the lamp assembly is formed on the cylindrical surface of the lower end of the connecting pin.

[0010] The upper surface of the middle part of the mounting chassis is formed with an annular convex edge for abutting against the lower surface of the second bearing inner ring, so that a rotation gap is formed between the lower surface of the bottom shell and the upper surface of the mounting chassis.

[0011] The rotating body also includes an outer shell arranged on the inner shell, and a mounting groove for mounting a fan blade is arranged at the edge between the outer shell and the inner shell.

[0012] A lampshade is arranged below the mounting chassis.

[0013] A quick-release connector with a screw thread is arranged above the hanger.

[0014] The beneficial effects of the utility model are:

[0015] 1. This ceiling fan with light is mainly composed of a hanger for installation on the ceiling wall, a base frame for installing the lamp assembly, and a rotating body for driving the fan blades and located between the hanger and the base frame. The connecting pin is fixed on the base frame to connect the hanger and the base frame. The rotating body forms a rotating assembly relationship with the connecting pin through the first bearing and the second bearing. The stator assembly on the connecting pin and the outer rotor assembly in the rotating body form a motor structure to drive the rotating body to rotate. Compared with the rotating structure of the traditional ceiling fan, the design of this rotating body adopts a double bearing design distributed up and down. On the one hand, there are mating ends at both ends of the rotating body, and the force is more evenly applied, making the rotation process of the rotating body more stable and smooth; on the other hand, the design of the upper and lower double bearings makes it less likely for the rotation axis of the outer rotor assembly to deviate relative to the central axis of the stator assembly when the outer rotor assembly rotates relative to the stator assembly for a long time, reducing the generation of noise and abnormal sound and increasing the service life.

[0016] 2. The upper end of the inner shell is formed with a first annular step for abutting against the upper surface of the first bearing outer ring, and the lower end of the bottom shell is formed with a second annular step for abutting against the lower surface of the second bearing outer ring. This design is used to reduce the up and down bouncing of the rotating body in the axial direction, further increase stability and reduce noise during operation.

[0017] 3. The annular convex edge in the middle of the mounting chassis forms a rotation gap between the lower surface of the bottom shell and the upper surface of the mounting chassis. On the one hand, it ensures that the rotating body will not interfere with the base frame during rotation. On the other hand, it separates the rotating body from the lamp assembly under the mounting chassis, thereby improving the overall heat dissipation efficiency.

[0018] 4. A connecting thread for installing the lamp assembly is formed on the cylindrical surface at the lower end of the connecting pin. This design facilitates the installation of the lamp and simplifies the structure.

[0019] 5. The quick-release connector installed above the hanger can match the screw thread of household lamps, which is simple and convenient to install and has good applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Reference Figure 2 , Figure 3 The base frame 3 includes a connecting pin 31 connected between the base frame 3 and the hanger 1. The upper and lower ends of the connecting pin 31 are respectively tightly sleeved with a first bearing 61 and a second bearing 62. The upper end of the rotating body 2 cooperates with the outer ring of the first bearing 61, and the lower end of the rotating body 2 cooperates with the outer ring of the second bearing 62, so that the rotating body 2 forms a rotation relationship relative to the hanger 1 and the base frame 3.

[0029] Reference Figure 3 , Figure 4 A stator assembly 32 is installed outside the connecting pin 31, and an outer rotor assembly 20 rotatably matched with the stator assembly 32 is installed inside the rotating body 2. The outer rotor assembly 20 and the stator assembly 32 form a motor structure to drive the rotating body 2 to rotate.

[0030] Furthermore, the ceiling fan with light is mainly divided into a hanger 1 for installation on the ceiling wall, a base frame 3 for installing the lamp assembly, and a rotating body 2 for driving the fan blades 4 and located between the hanger 1 and the base frame 3. The connecting pin 31 is fixed on the base frame 3 to connect the hanger 1 and the base frame 3. The rotating body 2 forms a rotational assembly relationship with the connecting pin 31 through the first bearing 61 and the second bearing 62. The stator assembly 32 on the connecting pin 31 and the outer rotor assembly 20 in the rotating body 2 form a motor structure to drive the rotating body 2 to rotate.

[0031] Compared to Figure 6 Compared with the rotating structure of the traditional ceiling fan, the design of the rotating body 2 adopts a double bearing design distributed up and down. On the one hand, there are matching ends at the upper and lower ends of the rotating body 2, and the force is more evenly applied, making the rotation process of the rotating body 2 more stable and smooth; on the other hand, the design of the upper and lower double bearings makes it less likely for the rotating axis of the outer rotor assembly 20 to deviate relative to the central axis of the stator assembly when the outer rotor assembly 20 rotates relative to the stator assembly 32 for a long time, thereby reducing the generation of noise and abnormal sound and increasing the service life.

[0032] Reference Figure 4 The rotating body 2 includes an inner shell 22 and a bottom shell 23 fixedly installed under the inner shell 22. The outer rotor assembly 20 is installed on the annular inner wall of the inner shell 22.

This design is used to reduce the up and down jumping of the rotating body 2 in the axial direction, further increase stability and reduce noise during operation.

[0034] Reference Figure 5 The base frame 1 also includes a mounting chassis 30, the lower end of the connecting pin 31 passes through the middle of the mounting chassis 30 and is fixed, and the cylindrical surface of the lower end of the connecting pin 31 is formed with a connecting thread 310 for installing the lamp assembly. This design facilitates the installation of the lamp assembly and simplifies the structure.

[0035] Reference Figure 4The upper surface of the middle part of the mounting chassis 30 is formed with an annular convex edge 300 for abutting against the lower surface of the inner ring of the second bearing 62, so that the lower surface of the bottom shell 230 and the upper surface of the mounting chassis 30 form a rotation gap 301. Further, the annular convex edge 300 in the middle part of the mounting chassis 30 forms a rotation gap 301 between the lower surface of the bottom shell 230 and the upper surface of the mounting chassis 30, which, on the one hand, ensures that the rotating body 2 will not interfere with the base frame 3 during the rotation process, and on the other hand, separates the rotating body 2 from the lamp assembly under the mounting chassis 30, thereby improving the overall heat dissipation efficiency.
