Abstract: An assembling structure of a ceiling fan has a motor shaft and a driving assembly mounted on the motor shaft. The motor shaft is mounted through the driving assembly. The driving assembly has an upper cover, a lower cover, a chamber, a circuit board, and a positioning mechanism. The lower cover has a covering board and a mounting cylinder mounted in a center of the covering board, and is mounted on the motor shaft via the mounting cylinder. The chamber is formed between the upper cover and the lower cover. The circuit board is mounted in the chamber. The upper cover, the lower cover, and the circuit board are sequentially arranged from top to bottom. The positioning mechanism is mounted in the chamber and limits a mounting position of the circuit board. The present invention solves the noise issue.

Abstract: The present invention provides a modular system having a first connection structure, a fan unit, and a circuit board unit. The circuit board unit includes a control and communication circuit board respectively electrically connected to a power module circuit board and a driver module circuit board. The driver module circuit board is electrically connected to a fan unit load of the fan unit. The power module circuit board, the control and communication circuit board, and the driver module circuit board are respectively mounted in a first protection shell of the first connection structure or in a fan protection shell of the fan unit. The modular system allows implementations of different circuit board structures for a ceiling fan with or without a pendant light. The modular system allows a control circuit board to more conveniently fit into the ceiling fan with or without the pendant light.

Abstract: A fan light has a fan assembly, a connecting assembly, and a lighting disc assembly. The fan assembly has a motor case, a main shaft, and multiple fan blades. The connecting assembly has a connecting unit main body having a main shaft connecting screw hole and multiple lighting disc fixing holes, a screw fixing hole formed on an inner surface of the main shaft connecting screw hole, and a fixing unit. The main shaft is mounted in the main shaft connecting screw hole. The fixing unit is mounted in the screw fixing hole to fix the main shaft. The lighting disc assembly has a lighting disc fixing shell having multiple lighting disc mounting holes. The lighting disc fixing shell is fixed on the top surface of the connecting unit main body via the lighting disc mounting holes and the lighting disc fixing holes.

Abstract: A mounting base of a ceiling fan has a mounting disc, a fitting sleeve, and a positioning unit. The mounting disc has a through hole. The fitting sleeve is mounted in the through hole and has a hanging block located on an end of the fitting sleeve. The fitting sleeve is hung on the mounting disc via the hanging block. An accommodating space is formed through the fitting sleeve and is adapted to accommodate a hanging rod. The positioning unit is mounted in the accommodating space and is capable of engaging with the hanging rod. The positioning unit has a bending edge. The positioning unit is hung on the fitting sleeve via the bending edge. The mounting base has a simplified assembling process and a great stability in mounting structure.

Abstract: A hanging head connecting mechanism of a ceiling fan has a connecting seat, a hanging rod, and a motor shaft. The connecting seat has a connecting plate, a first bushing, a second bushing, and multiple connecting pieces. The second bushing is located around the first bushing. The hanging rod is mounted in the connecting seat and disposed between the first bushing and the second bushing. The motor shaft is mounted in the connecting seat and disposed inside the first bushing. The connecting pieces are serially mounted through the second bushing, the hanging rod, and the motor shaft. Two of the connecting pieces are each mounted on a respective one of two opposite sides of the second bushing, and a wire-routing gap is formed between the first connecting piece and the second connecting piece.

Abstract: A ceiling fan has a motor and multiple fan blades. The motor has a stator assembly and a rotor assembly. The stator frame has a frame, a stator core, and multiple coils. The frame has multiple branch containers and multiple protrusions on the branch containers. The stator core is securely mounted in the frame. The coils are wound on the branch containers and protrusions. Therefore, the coils may be an ellipse and thus the magnetic flux therein is larger, which converts electric energy torques to drive the rotor assembly in higher efficiency. Besides, the rotor has multiple magnetic components and each magnetic component has a magnetic pole. An amount of the magnetic poles is larger than that of the branch containers. The motor can provide a higher torque even at a lower rotating speed.

Abstract: An assembling structure for a ceiling fan has a hanging rod, a hanging ball, and a hanging bracket. A top end of the hanging rod forms a bending edge. The hanging ball has a first hole and a supporting wall. The hanging rod is mounted through the first hole. The supporting wall has a supporting platform abutting a bottom surface of the bending edge. The hanging bracket has a ball mounting segment and a ceiling mounting segment adapted to be mounted to a ceiling. The ball mounting segment has a hanging hole. A diameter of the hanging hole is smaller than a diameter of the hanging ball. The hanging ball abuts downward a periphery of the hanging hole. The hanging rod is mounted through the hanging hole. With a large contact area between the hanging rod and the hanging ball, the structural strength is high.

Abstract: A light cover assembling structure has a light housing, a mounting sleeve, a light-emitting element, a transparent light cover, and a supporting cover. The mounting sleeve has an inner end mounted in the light housing and an outer end extending out of the light housing. An inner surface of the light housing and an outer surface of the mounting sleeve form an assembling space. The transparent light cover is mounted on the outer end of the mounting sleeve. The supporting cover is mounted on the outer end of the mounting sleeve, and has a first supporting side wall formed circumferentially and abutting the transparent light cover. The first supporting side wall of the supporting cover supports the transparent light cover such that the transparent light cover is firmly mounted on the mounting sleeve.

Abstract: A ceiling fan, including: a rotary shaft, a stator, and a rotor. The rotor includes an inner annular chamber, a magnetic-shoe fixation portion, a connection portion, and a bearing installation portion. The stator is housed in the inner annular chamber of the rotor. The bearing installation portion is disposed at one side of the magnetic-shoe fixation portion. One end of the connection portion is fixed on the magnetic-shoe fixation portion, and the other end of connection portion is fixed on the bearing installation portion. The magnetic-shoe fixation portion, the bearing installation portion are integrated with the connection portion. The geometric centers of the rotary shaft, the stator, the magnetic-shoe fixation portion, and the bearing installation portion are located in a straight line.
