DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

As shown inFIG.1throughFIG.7, the present invention discloses a motor and blade mounting structure100of a ceiling fan101. The ceiling fan101comprises a motor10, at least one bracket20, and at least one blade30.

The motor10has a housing11and a rotor12. The housing11includes an outer cover13. The rotor12is disposed in the housing11and the outer cover13.

The at least one bracket20has at least one mounting portion21. The rotor12of the motor10is fixedly connected to the at least one bracket20. The mounting portion21has a plurality of positioning holes22, a plurality of locking holes23, and a first hole24. The positioning holes22, the locking holes23and the first hole24pass through the at least one bracket20. Each positioning hole22communicates with a corresponding one of the locking holes23. The locking holes23are located at the outer sides of the positioning holes22, respectively. The first hole24is a screw hole. The at least one bracket20and the outer cover13form the housing11. The at least one bracket20is made of metal.

The mounting portion21of the at least one bracket20is configured for mounting the at least one blade30. The blade30includes a blade body31, a plurality of second screws32, a plurality of nuts33, a plurality of protruding posts321, a plurality of elastic washers34, a second hole311, two third holes312, a plate35, and a fixing member36. The second screws32are formed with the protruding posts321, respectively. One side of the blade body31is longitudinally formed with the protruding posts321, the second hole311and the third holes312. The plate35is located on one side of the blade body31, facing away from the at least one bracket20. The plate35has a fourth hole351corresponding to the first hole24, the second hole311and the fixing member36. One side of each protruding post321is fixedly connected to the plate35. The other side of each protruding post321passes through a corresponding one of the third holes312and extends toward the at least one bracket20to form a longitudinal post body322. One end of the post body322, adjacent to the at least one bracket20, extends laterally and outwardly to form a head portion323. The diameter of the head portion323is greater than the diameter of the post body322. The elastic washers34each have a body portion341. The body portions41of the elastic washers34are sleeved on the post bodies322of the protruding posts321, respectively. One side of the body portion341of each elastic washer34, adjacent to the head portion323of the corresponding protruding post321, extends laterally and outwardly to form an elastic spacer ring42. The head portions323of the protruding posts321and the elastic washers34correspond to the positioning holes22, respectively. The post bodies322of the protruding posts321and the body portions341of the elastic washers34correspond to the locking holes23, respectively. The diameter of each positioning hole22is greater than the diameter of the head portion323of each protruding post321and greater than the diameter of the elastic spacer ring342. The diameter of each locking hole23is less than the diameter of the head portion323of each protruding portion321and less than the diameter of the elastic spacer ring342. The plate35has a plurality of fifth holes352corresponding to the second screws32. The fifth holes352are configured for insertion of the second screws32. The plate35is made of metal. The second screws32pass through the fifth holes352and are locked by the nuts33on one side of the plate35, facing away from the at least one bracket20.

Referring toFIG.5, when the blade30is to be mounted, the head portions323of the protruding posts321and the elastic washers34pass through the respective locating holes22, and the post bodies322of the protruding posts321and the body portions341of the elastic washers34are displaced and locked in the respective locking holes23. As shown inFIG.6, when the protruding posts321are locked in the respective locking holes23, the body portions341of the elastic washers34are located between the respective protruding posts321and the at least one bracket20, and the elastic spacer rings342of the elastic washers34are located between the head portions323of the respective protruding posts321and the at least one bracket20, thereby reducing the wear of the at least one bracket20, the locking holes23and the protruding posts321greatly. The blade body31, the head portions323of the protruding posts321and the elastic spacer rings342of the elastic washers34are locked on both sides of the at least one bracket20. The plate35and the at least one bracket20are made of metal, which further increases safety, structural support and durability. Finally, the fixing member36is inserted from one side of the blade30, facing away from the at least one bracket20, to pass through the first hole24, the second hole311and the fourth hole351for fixing the blade body31and the plate35to the at least one bracket20. The fixing member36is a first screw361. The first screw361has a screw head362. When the first screw361is locked, the screw head362is located on one side of the plate35, facing away from the at least one bracket20, as shown inFIG.7, which also improves assembly convenience.

FIG.8is a schematic view of a second embodiment of the present invention when in use. The at least one bracket20includes two brackets20disposed the upper and lower sides of the motor10. The at least one mounting portion21is plural. The at least one blade30is plural. The mounting portions21are configured for mounting the blades30, respectively. This increases changes in the mounting position of the blades30and the air volume and direction of the airflow generated by the blades30.

Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
