Abstract

A ceiling fan, a hanger assembly of the ceiling fan, and a mounting bracket of the hanger assembly are designed with a lower failure rate. The hanger assembly of the ceiling fan includes a coupling rod and a fan rod. The mounting bracket has two lateral walls opposing to each other. Each of the two lateral walls includes a mounting end, a hanger end and a receiving portion. The coupling rod has two ends respectively received in the receiving portions of the two lateral walls. The fan rod has a first end coupled with the coupling rod, as well as a second end coupled with a stator of a motor of the ceiling fan.

First claim

What is claimed is:

1. A hanger assembly of a ceiling fan, comprising:
a mounting bracket having two lateral walls opposite to each other in a first direction, wherein each of the two lateral walls comprises a mounting end, a hanger end and a receiving portion, wherein the mounting end and the hanger end are spaced from each other in an axial direction perpendicular to the first direction, wherein the receiving portion is spaced from the hanger end in the axial direction, wherein the receiving portions of the two lateral walls are aligned with each other in the first direction, and wherein the receiving portion is in a form of a blind holes;
a coupling rod having two ends respectively received in the receiving portions of the two lateral walls; and
a fan rod having a first end coupled with the coupling rod, as well as a second end coupled with a stator of a motor of the ceiling fan.

2. The hanger assembly of the ceiling fan as claimed in claim 1 , wherein the first and second ends of the fan rod are spaced from each other in the axial direction.

3. A ceiling fan comprising:
the hanger assembly as claimed in claim 1 ;
a stator of a motor; and
a rotor of the motor coupled with a plurality of blades and rotatably coupled with the stator, wherein the stator is coupled with the second end of the fan rod and is configured to drive the rotor to rotate.

4. A hanger assembly of a ceiling fan, comprising:
a mounting bracket having two lateral walls opposite to each other in a first direction, wherein each of the two lateral walls comprises a mounting end, a hanger end and a receiving portion, wherein the mounting end and the hanger end are spaced from each other in an axial direction perpendicular to the first direction, wherein the receiving portion is spaced from the hanger end in the axial direction, wherein the receiving portions of the two lateral walls are aligned with each other in the first direction, wherein the receiving portion comprises a shrinking section having a larger end relatively adjacent to the mounting end, as well as a smaller end relatively adjacent to the hanger end, wherein the shrinking section has a maximal diameter in a second direction, as well as a minimal diameter in the second direction, wherein the maximal diameter is located at the larger end, wherein the minimal diameter is located at the smaller end, and wherein the shrinking section has a diameter that gradually reduces from the position of the maximal diameter to the position of the minimal diameter;
a coupling rod having two ends respectively received in the receiving portions of the two lateral walls, wherein the maximal diameter of the shrinking section is larger than an outer diameter of each of the two ends of the coupling rod, and wherein the minimal diameter of the shrinking section is smaller than or equal to the outer diameter of each of the two ends of the coupling rod; and
a fan rod having a first end coupled with the coupling rod, as well as a second end coupled with a stator of a motor of the ceiling fan.

5. The hanger assembly of the ceiling fan as claimed in claim 4 , wherein the receiving portion is in a form of an opening extending through the lateral wall in the first direction.

6. The hanger assembly of the ceiling fan as claimed in claim 4 , wherein the shrinking section comprises two lateral edges spaced from each other in the second direction, and wherein each of the two lateral edges is in a linear form on a plane perpendicular to the first direction.

7. The hanger assembly of the ceiling fan as claimed in claim 4 , wherein the minimal diameter of the shrinking section is equal to the outer diameter of each of the two ends of the coupling rod, wherein the shrinking section comprises two lateral edges spaced from each other in the second direction, wherein the receiving portion further comprises a connection section connected between the two lateral edges of the shrinking section at the smaller end of the shrinking section, and wherein the connection section is in an arched form.

8. The hanger assembly of the ceiling fan as claimed in claim 4 , wherein the minimal diameter of the shrinking section is smaller than the outer diameter of each of the two ends of the coupling rod, wherein the shrinking section comprises two lateral edges spaced from each other in the second direction, wherein the receiving portion further comprises a connection section connected between the two lateral edges of the shrinking section at the smaller end of the shrinking section, and wherein a spacing is formed between an outer periphery of each of the two ends of the coupling rod and an inner periphery of the connection section of the receiving portion of a respective one of the two lateral walls.

9. A hanger assembly of a ceiling fan, comprising:
a mounting bracket having two lateral walls opposite to each other in a first direction, wherein each of the two lateral walls comprises a mounting end, a hanger end and a receiving portion, wherein the mounting end and the hanger end are spaced from each other in an axial direction perpendicular to the first direction, wherein the receiving portion is spaced from the hanger end in the axial direction, and wherein the receiving portions of the two lateral walls are aligned with each other in the first direction;
A coupling rod having two ends respectively received in the receiving portions of the two lateral walls; and
a fan rod having a first end of coupled with the coupling rod via a connection member, as well as a second end coupled with a stator of a motor of the ceiling fan, wherein the connection member comprises a retaining portion and a coupling portion, wherein the retaining portion is fixed to the first end of the fan rod, wherein the coupling portion is pivotally coupled with the coupling rod, and wherein the coupling portion is capable of pivoting about an axle parallel to a second direction perpendicular to the axial direction and the first direction.

10. The hanger assembly of the ceiling fan as claimed in claim 9 , wherein the coupling portion is in a form of a though-hole and coupled with a shaft, and wherein the shaft is parallel to the second direction.

11. The hanger assembly of the ceiling fan as claimed in claim 10 , wherein the coupling rod comprises a hole through which the shaft extends.

12. The hanger assembly of the ceiling fan as claimed in claim 11 , wherein the coupling portion comprises a reducing portion, wherein the reducing portion comprises a larger end relatively adjacent to the first end of the fan rod, as well as a smaller end relatively distant to the first end of the fan rod, wherein the reducing portion has an inner diameter that gradually reduces from the larger end to the smaller end, wherein the reducing portion has a maximal inner diameter in the first direction, as well as a minimal inner diameter in the first direction, wherein the maximal inner diameter is located at the larger end, wherein the minimal inner diameter is located at the smaller end, wherein the shaft has an outer diameter at each of two ends thereof, wherein the reducing portion has an inner diameter that gradually reduces from the position of the maximal inner diameter to the position of the minimal inner diameter, wherein the maximal inner diameter is larger than the outer diameter, and wherein the minimal inner diameter is smaller than or equal to the outer diameter.
