[0031] Reference Figure 5 This utility model proposes a ceiling fan that improves assembly efficiency by simplifying the structure. The ceiling fan includes a housing assembly 100, a motor assembly 200, multiple fan blades 300, and a pressure plate 400.

[0032] The ceiling fan's housing assembly 100 serves as the mounting base. The housing consists of an upper half-shell 101 and a lower half-shell 102, which are tightly joined by a detachable connection method (such as screws, clips, or magnetic attraction), forming an internal mounting cavity. This cavity houses the electronic control board 500 and the battery assembly 600. The upper half-shell 101 can be disassembled to inspect or replace the internal electronic components. The lower half-shell 102 serves as the main assembly platform, with a support portion 103 at its center. This support portion 103 extends downwards, forming an mounting channel to accommodate a bushing 110. The bushing 110 serves as the support structure for the rotor 220's shaft 221, with its bottom wall tightly abutting against the inner wall of the support portion 103 to prevent displacement and facilitate stable rotation of the shaft 221. The material selection for the bushing 110 must consider wear resistance and lubricity to reduce frictional loss and noise during rotation; a copper alloy is a suitable material.

[0033] The motor assembly 200 is the power source of the ceiling fan, which comprises a stator 210 and a rotor 220, the stator 210 is fixed on the outer wall of the support part 103, such as interference fit, bolt or other fasteners, and the rotor 220 is located outside the stator 210, the center of the rotor 220 is provided with a rotating shaft 221, the upper end of the rotating shaft 221 penetrates through the shaft sleeve 110 and is limited by a snap spring. The outer shell of the rotor 220 is designed as a rotating seat 230, the lower end surface of the rotating seat 230 is uniformly distributed with a plurality of mounting parts 231, which provide necessary connecting points for the assembly of the fan blades 300. The assembly of each mounting part 231 and the assembly part 310 of the fan blade 300 is connected by the way of bolt and hole, which ensures the relative fixation of the fan blade 300 in the circumferential direction, effectively prevents the loosening of the fan blade 300 during rotation, and ensures the safe operation of the ceiling fan. The pressure plate 400 is an important part of the fixing structure of the fan blade 300, which is fixedly connected to the lower end surface of the rotating seat 230, and is realized by bolt, riveting or other reliable connection mode. The design of the pressure plate 400 makes the lower end surface of all the assembly parts 310 of the fan blades 300 be uniformly and firmly pressed, effectively preventing the risk of falling of the fan blades 300 during high-speed rotation.

[0034] The ceiling fan with the above structure has obvious technical effects and application advantages. First, the detachable design of the shell assembly 100 greatly simplifies the assembly process, second, the integrated design of the motor assembly 200 and the lower half shell 102 of the shell makes the assembly process of the whole ceiling fan more efficient, reduces the number of parts and improves the production efficiency. Thirdly, the design of the rotor 220 shell as the rotating seat 230 not only reduces the weight, but also makes the ceiling fan more convenient to pack and store by simplifying the assembly structure, thereby reducing the logistics cost. In addition, the connection mode of the bolt and the hole makes the assembly of the fan blade 300 simple and easy to operate, without the need for complex tools or professional skills, greatly shortening the installation time.

[0035] In some embodiments of the utility model, the lower half shell 102 is made by injection molding process, the lower half shell 102 is integrally injection molded with the support part 103, the support part 103 is a key structure of the ceiling fan, which plays an important role in supporting and fixing the motor assembly 200. By integrally injection molding, the support part 103 is closely combined with the lower half shell 102, avoiding additional assembly steps and improving the stability of the overall structure. The shaft sleeve 110 and the support part 103 are fixed by interference fit, which is a close fit method, the outer diameter of the shaft sleeve 110 is slightly larger than the inner diameter of the support part 103, and the close combination is realized by pressing or thermal expansion and cold contraction during installation, effectively preventing the loosening of the shaft sleeve 110 during operation, improving the operation stability and safety of the ceiling fan.

[0036] Similarly, the stator 210 is also in interference fit with the support part 103, and the stator 210 is a key part of the ceiling fan motor, and its stable installation is crucial for the normal operation of the ceiling fan. Through the interference fit, the stator 210 is firmly fixed on the support part 103, ensuring the efficient and stable operation of the ceiling fan.
