Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the utility model provides a ceiling fan that flabellum double-end is fixed, as shown in fig. 1-4, it includes motor 1 and flabellum 2, and motor 1 includes stator module 11 and rotor subassembly 12, and the relative stator module 11 of rotor subassembly 12 rotates, and stator and rotor all belong to the common structure of motor, do not give consideration to its inner structure here and give unnecessary details. The rotor assembly 12 has an upper end surface and a lower end surface, both defined in the height direction, and when the ceiling fan is mounted and fixed, the top end surface is defined as the upper end surface and the bottom end surface is defined as the lower end surface. One end of the fan blade 2 close to the motor 1 is provided with a first connecting piece 21 and a second connecting piece 22, the first connecting piece 21 is fixed on the upper end face of the rotor assembly 12, the second connecting piece 22 is fixed on the lower end face of the rotor assembly 12, and when the rotor assembly 12 rotates, the first connecting piece 21 and the second connecting piece 22 drive the fan blade 2 to rotate. The fixing mode forms multi-point fixing, and the upper and lower double-point fixing can keep the coordination of the fan blades, thereby enhancing the stability of fan blade fixing. As shown in the drawings, the first connecting member 21 and the second connecting member 22 may be fixedly connected to the rotor assembly 12 by screws, but may also be fixedly connected by other fixing methods such as welding.

In one embodiment, as shown in fig. 1 and 2, the first connecting member 21 and the second connecting member 22 are fixedly connected through an intermediate connecting plate 23, the intermediate connecting plate 23 is located outside the motor 1, the fan blade 2 is fixed on the outer side surface of the intermediate connecting plate 23, and the first connecting member 21, the second connecting member 22, the intermediate connecting plate 23 and the fan blade 2 can be integrally connected, so that the overall structural strength of the fan blade 2 is effectively enhanced.

The first connecting member 21 is a first connecting plate, the second connecting member 22 is a second connecting plate, both of which are plate-shaped structures, and the first connecting plate and the second connecting plate are parallel to each other and extend toward the axis of the motor 1. The upper end face and the lower end face of the rotor assembly 12 are generally flat, and the plate-shaped structures of the first connecting piece 21 and the second connecting piece 22 are respectively attached to the upper end face and the lower end face, which is equivalent to increase the fixing area and is helpful to enhance the fixing effect.

As shown, the middle connecting plate 23 is in the shape of a circular arc protruding toward the outside of the motor 1, where the outside of the motor is away from the motor 1. The arc-shaped structure can prevent the intermediate connecting plate 23 from contacting with the motor 1, and can play a certain role in reducing wind resistance.

In one embodiment, the structure of the motor 1 will be specifically described. As shown in fig. 3 and 4, the main body of the rotor assembly 12 has a ring structure, the main body of the stator assembly 11 has a cylindrical shape, and the rotor assembly 12 is located on the outer circumferential surface of the stator assembly 11 and is disposed around the stator assembly 11.
