Description

Technical Field

[0001] The utility model relates to the technical field of ceiling fans, in particular to a ceiling fan motor. Background Art

[0002] Traditional ceiling fan motors have two end caps, one at the top and one at the bottom. After the motor is installed, the light panel is installed on the thread of the lower shaft. Generally speaking, there are several problems:

[0003] 1. Generally, thread lock glue is needed to prevent loosening, but rework is difficult after adding glue.

[0004] 2. In order not to affect the installation of fan blades, the lamp panel is generally small and cannot play a role in heat dissipation

[0005] 3. The shaft thread is connected to the lamp panel thread. The verticality of the lamp panel end face and the shaft extension cannot be guaranteed, which may cause the lamp panel and the motor to be non-parallel, resulting in "large and small edges". Utility Model Content

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a ceiling fan motor to solve the problems in the background technology.

[0007] In view of this, the utility model provides a ceiling fan motor, comprising:

[0008] A motor having a housing on the outside of the motor, wherein the fan blades are mounted on the end surface of the housing;

[0009] A bottom plate, which serves as a lamp tray and is used to directly contact and fix the LED lamp panel, and is provided with a plurality of protruding mounting posts;

[0010] The stator core is punched with corresponding positioning and mounting holes, and the positioning and mounting holes are used to accommodate the mounting columns on the base plate, and the base plate is fixed to the stator core by screws.

[0011] Optionally, the diameter of the base plate is smaller than the diameter of the motor, and the diameter difference range is 1-10 mm, thereby providing a good heat dissipation effect.

[0012] Optionally, the number of the mounting posts is set to at least three and evenly distributed on the base plate to ensure stability and parallelism of the lamp panel installation.

[0013] Optionally, the base plate is made of aluminum alloy or magnesium alloy to further enhance heat dissipation performance.

[0014] Optionally, the positioning and mounting holes on the stator core match the shape of the mounting posts to ensure a tight fit between the two and improve the overall structural strength.

[0015] It can be seen from the above technical solutions that the embodiments of the present invention have the following advantages:

[0016] 1. The utility model provides a ceiling fan motor that directly connects the base plate to the stator core and secures it with screws, replacing the traditional threaded and glued method. This method not only simplifies the assembly process but also makes subsequent disassembly and rework more convenient and quick, reducing maintenance difficulty and cost. The base plate serves as a lamp panel, and its size is almost the same as the entire motor diameter, only 1-10 mm smaller, greatly increasing the heat dissipation area. At the same time, the base plate is made of high thermal conductivity materials such as aluminum alloy or magnesium alloy, which can quickly conduct and dissipate the heat generated during the operation of the generator, improving heat dissipation efficiency and extending the service life of the motor.

[0017] 2. This utility model features a ceiling fan motor with a flat stator core end face. The mounting posts on the baseplate match the positioning holes on the core, ensuring a close fit and parallelism between the two. This not only improves the overall structural strength and stability, but also eliminates the "large and small edges" phenomenon, enhancing product aesthetics and user satisfaction.

[0018] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0026] A ceiling fan motor according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0027] For easier understanding, see Figures 1 to 4 The present invention provides an embodiment of a ceiling fan motor 1, comprising:

[0028] A motor 1, wherein the motor 1 has a housing on the outside, wherein the fan blades are mounted on the end surface of the housing;

[0029] A bottom plate 11, which serves as a lamp tray and is used to directly contact and fix the LED lamp board 16, and the bottom plate 11 is provided with a plurality of protruding mounting posts 12;

[0030] The stator core 13 has corresponding positioning and mounting holes 14 punched out thereon. The positioning and mounting holes 14 are used to accommodate the mounting posts 12 on the base plate 11 , and the base plate 11 is fixed to the stator core 13 by screws 15 .

[0031] It should be noted that the direct connection between the bottom plate 11 and the stator core 13 not only simplifies the assembly process, but also enhances the heat dissipation performance and ensures good mechanical stability and parallelism.

[0032] The motor 1 in this embodiment adopts a double-bearing structure at one end, reducing the design of the traditional upper and lower end covers, and the middle part of the motor 1 is provided with a shaft 2. The outside of the motor 1 is wrapped with an outer shell to protect the internal components and fix the fan blades. The base plate 11 is used as a lamp panel, which directly contacts and fixes the LED light board 16. A plurality of protruding mounting columns 12 are provided on the base plate 11. These mounting columns 12 are used to cooperate with the positioning mounting holes 14 on the stator core 13 to achieve a stable connection between the base plate 11 and the core. Positioning mounting holes 14 that match the mounting columns 12 of the base plate 11 are punched out on the stator core 13. The base plate 11 is fixed to the stator core 13 by screws 15, avoiding the rework problem caused by the traditional use of thread locking glue.

[0033] In some embodiments, the diameter of the base plate 11 is smaller than the diameter of the motor 1 , and the diameter difference ranges from 1 to 10 mm.

[0034] It should be noted that the diameter of the base plate 11 is slightly smaller than the diameter of the motor 1, and the difference between the two is controlled between 1 and 10 mm. This structural setting can not only ensure sufficient space to accommodate the base plate 11, but also enable the base plate 11 to serve as an effective heat sink.

[0035] In some embodiments, the number of the mounting posts 12 is set to at least three and evenly distributed on the base plate 11 .

[0036] It should be noted that the number of the mounting posts 12 is no less than three and is evenly distributed around the base plate 11 to ensure stability and parallelism when the lamp panel is installed. Example

[0037] In some embodiments, the base plate 11 is made of aluminum alloy or magnesium alloy.

[0038] It should be noted that the bottom plate 11 is made of aluminum alloy or magnesium alloy. Both materials have good thermal conductivity and can effectively dissipate the heat generated during the operation of the generator 1.

[0039] In some embodiments, the positioning and mounting holes 14 on the stator core 13 match the shape of the mounting posts 12 to ensure a tight fit between the two.

[0040] It should be noted that the shapes of the mounting posts 12 and the positioning mounting holes 14 on the stator core 13 match each other to ensure a close fit and improve the overall structural strength.

[0041] Working principle: The base plate 11 serves as a lamp panel and also acts as a heat sink. It directly contacts and fixes the LED light panel 16, and because the base plate 11 is made of high thermal conductivity materials such as aluminum alloy or magnesium alloy, it can quickly transfer the heat generated during the operation of the motor 1 to the base plate 11. The size of the base plate 11 is close to the diameter of the entire motor 1, which increases the heat dissipation area and further improves the heat dissipation efficiency. In addition, the airflow driven by the operation of the motor 1 also helps to accelerate the heat dissipation on the surface of the base plate 11. The multiple mounting posts 12 on the base plate 11 are evenly distributed, and these mounting posts 12 match the shape of the positioning mounting holes 14 on the stator core 13. The base plate 11 is fixed to the stator core 13 by screws 15, forming a strong and stable connection. It not only ensures a close fit between the base plate 11 and the motor 1, but also avoids the loosening problem that may be caused by traditional threaded connections. There is no need to use thread fasteners, which simplifies assembly and subsequent maintenance. Because screws 15 secure the base plate 11 to the stator core 13, eliminating the need for thread-locking adhesive, greatly facilitates maintenance and rework. The base plate 11 and stator core 13 are secured with screws 15, eliminating the need for thread-locking adhesive. Therefore, when maintenance or component replacement is required, the base plate 11 can be easily removed, greatly facilitating rework. This is particularly important for repairs and upgrades throughout the product's lifecycle.

[0042] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
