Ceiling fan structure

A ceiling fan structure includes a mounting bracket, a hanging plate, a coupling, and a motor. The mounting bracket is fixed to a ceiling. The hanging plate has a top fixed to the mounting bracket. The top is formed with a recessed accommodating groove for accommodating a first electronic component. The coupling is connected to a bottom of the accommodating groove and extends downward. The coupling is connected with a support plate extending horizontally. The support plate is configured to support a second electronic component. The internal space of the ceiling fan structure is properly planned so that the components of the ceiling fan structure can be reasonably configured, so as to improve the efficiency of assembly.

FIELD OF THE INVENTION

The present invention relates to a fan, and more particularly to a ceiling fan structure.

BACKGROUND OF THE INVENTION

As shown inFIG.4, a conventional ceiling fan structure includes a mounting bracket81fixed to a ceiling. A rod82is coupled under the mounting bracket81for hanging a motor and fan blades. The rod82is further fixed to a support plate83. The support plate83is configured to support various electronic components used for controlling the motor, such as a forward/reverse rotation controller91, a receiver92, a capacitor93, a circuit board, and so on. However, the above-mentioned various electronic components need to be connected to each other by wires. Due to the large number of components, the wiring work is very complicated and error-prone. In addition, since the above-mentioned various electronic components are arranged on the support plate, the space is not enough to cause the components and their wires to crowd each other, which has the disadvantage of affecting heat dissipation.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a ceiling fan structure. The internal space of the ceiling fan structure is properly planned so that the components of the ceiling fan structure can be reasonably configured, so as to improve the efficiency of assembly.

In order to achieve the foregoing object, the present invention provides a ceiling fan structure, comprising:

a mounting bracket fixed to a ceiling;

a hanging plate, having a top fixed to the mounting bracket, the top being formed with a recessed accommodating groove for accommodating a first electronic component;

a coupling, connected to a bottom of the accommodating groove and extending downward, the coupling being connected with a support plate extending horizontally, the support plate being configured to support a second electronic component;

a motor, connected to the coupling.

Preferably, the first electronic component is a receiver, the second electronic component is a motor forward/reverse rotation module, and the motor forward/reverse rotation module is provided with an integrated output flat cable connector.

Preferably, the accommodating groove is surrounded by four connected side walls connected to the top and a bottom wall connected to the four side walls, and the first electronic component is a receiver.

Preferably, one of the side walls is formed with a wire hole through which a wire passes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring toFIG.1throughFIG.3, the present invention discloses a ceiling fan structure, comprising a mounting bracket1, a hanging plate2, a coupling3, a motor4, and a housing5. The mounting bracket1is fixed to a ceiling. The hanging plate2has a top21. The top21is formed with a plurality of gourd-shaped holes211. The mounting bracket1is provided with a plurality of screws11. The hanging plate2is rotatably coupled to the mounting bracket1through the cooperation of the gourd-shaped holes211and the screws11.

The middle portion of the top21of the hanging plate2is recessed downward to form four connected side walls22connected to the top21and a bottom wall23connected to the four side walls22. A rectangular accommodating groove24is defined between the four side walls22and the bottom wall23to provide a first accommodating space25for accommodating a receiver6. Furthermore, one of the side walls22is formed with a wire hole221for the wire of the receiver6to extend out of the accommodating groove24.

The top end of the coupling3is locked to the bottom wall23, and the bottom end of the coupling3extends downward and is connected to the motor4, thereby hanging and positioning the motor4on the ceiling. The coupling3is connected with a support plate31extending horizontally. A second accommodating space32is defined above the support plate31to support a motor forward/reverse rotation module7. The motor forward/reverse rotation module7is a component that integrates a controller used for controlling the forward/reverse rotation of the motor4and a capacitor used for controlling the speed of the motor4, and that integrates its wire connectors into an output flat cable connector (not shown in the figure). Accordingly, only the output flat cable connector needs to be wired in the assembly process, instead of wiring each electronic component one by one, so as to simplify the assembly and save time.

The mounting bracket1is formed with a plurality of gourd-shaped holes12. The housing5is provided with a plurality of screws51. The housing5is rotatably coupled to the mounting bracket1through the cooperation of the gourd-shaped holes12and the screws51, and covers various components of the ceiling fan, including the hanging plate2, the coupling3and the motor4.

With the above structure, the present invention properly plans the space inside the ceiling fan for the hanging plate2to form the accommodating groove24, and the receiver6is arranged in the accommodating groove24, without installing on the support plate31. In addition, the present invention may be a ceiling fan without a receiver in the original specifications. The accommodating groove of the hanging plate is provided for the user to install the receiver thereafter to facilitate the assembly. Accordingly, since the receiver6and the motor forward/reverse rotation module7are respectively located in the accommodating groove24and on the support plate31, they will not crowd each other. Thus, other components can have a reasonable configuration, so that the internal components of the ceiling fan are kept at an appropriate distance to facilitate ventilation and heat dissipation.
