These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0024] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this disclosure pertains.

[0026] In the description of this disclosure, it should be understood that some directional terms are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. In the embodiments of this disclosure, terms such as "upper," "lower," and "side" are generally used to indicate orientation. Figure 2 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0027] To make the technical solutions and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0028] In related technologies, the motor of a fan light is typically pre-manufactured as a separate component and then fixed to the light panel using connectors such as screws. For example, Figure 1 As shown, Figure 1 This is a structural diagram of a fan light in related technologies, where A represents the motor and B represents the lamp panel. The motor A is mounted on the lamp panel B. Because the motor needs to be manufactured separately as an independent part, it not only increases the material and manufacturing costs of the motor itself but also requires an additional secondary assembly process between the motor and the lamp panel, resulting in higher overall material and labor costs for the fan light. Furthermore, the secondary connection between the motor and the lamp panel generates accumulated assembly tolerances, causing concentricity deviations and leading to poor dynamic balance during fan operation. This results in uneven speed, overall vibration, and other problems, affecting the user experience and shortening the product's lifespan, thus resulting in poor overall performance of the fan light.

[0029] In addition, the independent motor itself has a certain axial thickness, and the assembly gap between the motor and the lamp panel will result in the overall axial thickness of the fan light being too large, which does not conform to the current development trend of home decoration appliances being thinner and more invisible, and affects the aesthetics of the product.

[0030] In order to solve the technical problems existing in the related technologies, the present disclosure provides a fan light with low overall manufacturing cost.

[0031] See Figures 2-5 ,in Figure 2 This is a schematic diagram of the structure of a fan light provided in an embodiment of this disclosure. Figure 3 This is an exploded view of a fan light provided in an embodiment of this disclosure. Figure 4 This is a cross-sectional view of a fan light provided in an embodiment of the present disclosure. Figure 5 for Figure 4 The enlarged view of the portion circled in the dashed circle shows that this embodiment of the present disclosure provides a fan light, including: a shaft 1, a stator assembly 2, a rotor assembly 3, a lighting assembly 4, and a fan blade assembly 5.

[0032] See Figure 2 , Figure 3 and Figure 4 Shaft 1 serves as a fixed support member, with one end fixedly connected to a ceiling (not shown in the figure) and the other end extending axially. Fan blade assembly 5 is sleeved on shaft 1, and lighting assembly 4 is fixedly connected to shaft 1. The lighting assembly 4 and fan blade assembly 5 are arranged at intervals along the axial direction of shaft 1, so that the lighting assembly 4 and fan blade assembly 5 do not affect each other when they are working.

[0033] See Figure 4The stator assembly 2 is fixedly connected to the side of the lighting assembly 4 facing the fan blade assembly 5, and the rotor assembly 3 is fixedly connected to the side of the shaft 1 and / or the fan blade assembly 5 facing the lighting assembly 4, so that the stator assembly 2 is directly connected to the lighting assembly 4 and the rotor assembly 3 is directly connected to the fan blade assembly 5.

[0034] See Figure 5 The stator assembly 2 and the rotor assembly 3 are arranged axially on the shaft 1, and an axial air gap 00 is formed between the stator assembly 2 and the rotor assembly 3 to form a heat dissipation channel inside the fan lamp. The airflow generated by the rotation of the fan blade assembly 5 is used to dissipate heat from the stator assembly 2, which achieves good heat dissipation, helps to extend the service life of the electric fan, and improves the overall performance of the electric fan.

[0035] When the user needs to use the fan function of the fan light, the stator assembly 2 is energized and generates an axial rotating magnetic field. The rotor assembly 3 is subjected to the force of this rotating magnetic field and generates electromagnetic torque, which drives the fan blade assembly 5 to rotate around the shaft 1, thus realizing the rotating air supply function of the fan light.

[0036] The fan light provided in this embodiment of the present disclosure replaces the motor of the fan light in the related art by fixing the stator assembly 2 to the lighting assembly 4 and the rotor assembly 3 to the shaft 1 and / or the fan blade assembly 5. This eliminates the need for manufacturing and assembling an independent motor, reduces material and labor costs, and thus lowers the overall manufacturing cost of the entire fan light.

[0037] Furthermore, due to this structural design, the motor of the fan light is no longer a separate component, but is integrated into the fan light structure, making the fan light axially compact and effectively reducing the overall thickness of the fan light to meet the requirements of thin design.

[0038] The structure of the fan light provided in the embodiments of this disclosure will be described in detail below: Shaft 1 serves as the suspension connection component for the entire fan light and can be made of metal materials, such as stainless steel or aluminum alloy, to ensure sufficient strength and rigidity.

[0039] For example, see Figure 2 , Figure 3 and Figure 4 The upper end of shaft 1 is connected to a mounting base and is connected to a ceiling, etc., through the mounting base. The lower end supports the fan blade assembly 5 and the lighting assembly 4 in sequence along the axial direction. The fan blade assembly 5 can rotate around shaft 1, and the lighting assembly 4 is fixedly connected to shaft 1.

[0040] The stator assembly 2, as the core component of the motor drive, is fixedly connected to the side of the lighting assembly 4 facing the fan blade assembly 5 and is coaxially arranged with the shaft 1. It is used to cooperate with the rotor assembly 3 to form a disc motor to drive the fan blade assembly 5 to rotate.

[0041] See Figure 6 ,in Figure 6 This is a schematic diagram of the stator assembly and rotor assembly in a fan lamp provided in an embodiment of the present disclosure. In this embodiment, the stator assembly 2 includes a coil 21 and a stator core 22.

[0042] The coil 21 is wound around the stator core 22. When the coil 21 is energized, the stator core 22 generates a rotating magnetic field, which interacts with the rotor assembly 3 and drives the fan blade assembly 5 to rotate.

[0043] See also Figure 6 The stator core 22 has an axial surface 221 on the side facing the rotor assembly 3, which extends radially along the shaft 1. Since the axial surface 221 of the stator core 22 is a flat radially extending surface, it forms a uniform axial air gap 00 with the magnetic component 31 of the rotor assembly 3, making the magnetic field distribution more uniform and improving the motor efficiency and running stability.

[0044] Exemplarily, the number of coils 21 is multiple, and the multiple coils 21 constitute multiple coil groups, each coil group including at least one coil. Exemplarily, as... Figure 6 As shown, the stator core 22 is annular and includes multiple spaced fixing parts, each fixing part corresponds to a coil group, and each coil group includes multiple coils.

[0045] The rotor assembly 3, as the core component of the motor drive, is fixedly connected to the side of the fan blade assembly 5 facing the lighting assembly 4 and is coaxially arranged with the shaft 1. It is used to cooperate with the stator assembly 2 to form a disc motor to drive the fan blade assembly 5 to rotate.

[0046] See Figure 4 and Figure 6 In this embodiment of the disclosure, the rotor assembly 3 includes a magnetic element 31, which is used to generate a magnetic field and rotate under force.

[0047] The magnetic component 31 is fixedly connected to the side of the fan blade assembly 5 facing the lighting component 4, meaning that the magnetic component 31 is directly fixed to the fan blade assembly 5. This makes the magnetic component 31 and the fan blade assembly 5 form an integral structure, avoiding the cumulative tolerances caused by assembly in related technologies. This better ensures the concentricity of the magnetic component 31 and the shaft 1, reduces eccentric vibration during rotation, and makes the fan light run more smoothly and with lower noise. At the same time, since the magnetic component 31 can directly drive the fan blade assembly 5 to rotate, there is no need for intermediate transmission mechanisms such as gears, resulting in higher transmission efficiency.

[0048] Furthermore, an axial air gap 00 is formed between the magnetic component 31 and the stator assembly 2, constituting a disc motor structure, which greatly reduces the overall thickness of the motor, achieving an ultra-thin fan light and facilitating diverse shapes.

[0049] In some embodiments, see Figure 6 and Figure 7 ,in Figure 7 This is a partial structural diagram of a fan light provided in an embodiment of the present disclosure. The magnetic component 31 can be a ring-shaped magnet 311. By setting the magnetic component 31 as a ring structure, the mass and magnetic pole distribution of the rotor in the circumferential direction can be ensured to be uniform, which helps to reduce the dynamic imbalance of the rotor caused by the eccentricity or uneven distribution of the magnets.

[0050] In this embodiment, the annular magnet 311 is bonded and fixed to the side of the fan blade assembly 5 facing the lighting assembly 4, and is coaxial with the shaft 1, which makes the installation of the annular magnet 311 simple, and reduces manufacturing costs and assembly tolerances while ensuring positioning accuracy.

[0051] For example, the annular magnet 311 can be a one-piece annular permanent magnet. By making the annular magnet 311 a one-piece structure, not only is the manufacturing process simple and assembly convenient, but the magnet itself also has high strength and is not prone to local deformation or detachment under the action of high-speed rotating centrifugal force, resulting in high reliability. Alternatively, the annular magnet 311 can be a ring structure formed by splicing multiple magnet blocks along the circumference. By splicing multiple magnet blocks to form a ring structure, the use of permanent magnet material can be saved, which helps to reduce the manufacturing cost of the annular magnet 311. In particular, when individual magnet blocks are damaged, it is not necessary to replace the entire annular magnet; only the damaged magnet block needs to be replaced, which not only facilitates maintenance but also reduces maintenance costs.

[0052] The lighting component 4 serves as the lighting function execution component of the fan light, and is used to realize the lighting function of the fan light.

[0053] See Figure 3 and Figure 4 In this embodiment of the present disclosure, the lighting component 4 includes a lamp panel 41 and a lamp strip 42.

[0054] The lamp panel 41 is a disc-shaped structure, fixedly connected to the shaft 1, and remains stationary together with the shaft 1. The lamp strip 42 is fixedly connected to the side of the lamp panel 41 away from the fan blade assembly 5, and is used to emit light after being powered on.

[0055] Since the lamp panel 41 has a disc-shaped structure and a large area, by fixing the lamp strip 42 to the side of the lamp panel 41 away from the fan blade assembly 5, the heat generated by the lamp strip 42 can be directly transferred to the lamp panel 41 for heat dissipation. In particular, when the fan blade assembly 5 rotates, the negative pressure it generates can promote airflow on the side of the lamp panel 41 close to the fan blade assembly 5, which helps the lamp panel 41 dissipate heat.

[0056] Combination Figure 4 and Figure 5By placing the light strip 42 and the disc motor composed of the stator assembly 2 and the rotor assembly 3 on opposite sides of the light panel 41, the lighting function and motor drive function of the fan light are physically isolated through the light panel 41. When the fan light requires maintenance, the stator assembly 2 or the rotor assembly 3 can be directly repaired by removing the light panel 41 without disassembling the fan blade assembly 5, making maintenance convenient and efficient.

[0057] See Figure 4 or Figure 5 The stator assembly 2 is installed on the side of the lamp panel 41 facing the fan blade assembly 5 and is coaxial with the shaft 1 to ensure that the stator assembly 2 is coaxial with the shaft 1.

[0058] See Figure 5 The stator core 22 is fixedly connected to the lamp panel 41 by at least two fasteners 7, which are arranged at intervals along the circumference of the stator assembly 2.

[0059] In this way, the stator core 22 is fixedly connected to the lamp panel 41 by at least two fasteners 7, which prevents the stator assembly 2 from shifting or deviating during operation and ensures the long-term stability of the stator assembly 2. Furthermore, arranging at least two fasteners 7 at intervals along the circumference of the stator assembly 2 avoids stress concentration or fatigue failure caused by relying on a single fastener, which is beneficial to the reliability of the connection and the service life of the structure.

[0060] For example, see Figure 5 The fastener 7 can be a screw. By passing the screw through the mounting hole of the lamp panel 41 and screwing it into the mounting hole of the stator core 22, the lamp panel 41 and the stator core 22 can be quickly and accurately positioned, ensuring that the stator core 22 is coaxial with the shaft 1.

[0061] In addition, when the fastener 7 is a screw, the lamp panel 41 and the stator core 22 are detachably connected. When the stator assembly 2 needs to be repaired, for example when the coil is short-circuited, the stator core 22 can be separated from the lamp panel 41 simply by turning the screw, which reduces the maintenance cost.

[0062] See Figure 5 In this embodiment of the present disclosure, a positioning structure 411 is provided on the side of the lamp panel 41 facing the fan blade assembly 5, and the stator assembly 2 is positioned and connected to the lamp panel 41 through the positioning structure 411.

[0063] By setting the positioning structure 411, a radial reference is provided for the stator assembly 2 when it is assembled onto the lamp panel 41, ensuring that the stator assembly 2 remains coaxial with the shaft 1 and the fan blade assembly 5. That is, during the assembly or maintenance of the fan lamp, whether by manual or adaptive positioning, the positioning structure 411 can be used to position the stator assembly 2, which is not only convenient to operate but also meets the accuracy requirements for the assembly of the stator assembly 2.

[0064] For example, see Figure 8 ,in Figure 8 This is a partial structural diagram of a fan light provided in an embodiment of the present disclosure. The positioning structure 411 can be an annular protrusion, and the outer wall of the stator core 22 abuts against the inner wall of the annular protrusion. On the one hand, this annular protrusion structure allows for a larger contact area between the positioning structure 411 and the stator core 22, thereby effectively resisting the radial electromagnetic force, rotational inertia force, and external impacts experienced by the stator assembly 2 during operation, preventing radial movement or displacement of the stator assembly 2 during long-term use, and significantly enhancing the fixing rigidity of the stator assembly 2. On the other hand, the annular protrusion structure can also ensure that the stator core 22 and the fan blade assembly 5 are coaxial, thereby reducing vibration and noise caused by coaxiality deviation, and further improving the stability and reliability of the fan light operation.

[0065] It should be noted that the positioning structure 411 can also be other structural forms, such as multiple positioning protrusions or annular step structures arranged at intervals along the circumference, which are not specifically limited in the embodiments disclosed herein.

[0066] See Figure 8 The lamp panel 41, facing the fan blade assembly 5, includes an annular boss 412 and multiple radial ribs 413. The radial ribs 413 are evenly distributed radially along the circumference of the annular boss 412. The positioning structure 411 is located on the surface of the annular boss 412 facing the fan blade assembly 5. Thus, the positioning structure 411 is further utilized using the annular boss 412, while the strength of the annular boss 412 is enhanced by the multiple radial ribs 413, achieving better heat dissipation.

[0067] Further, see Figure 8 One end of each radial rib 413 is fixedly connected to the annular boss 412, and the other end extends to the inner or outer edge of the lamp disk 41, so that the radial rib 413 helps to enhance the radial support stiffness of the stator assembly 2, so as to ensure that the stator core 22 and the fan blade assembly 5 rotate coaxially.

[0068] The fan blade assembly 5 serves as the air supply function actuator of the fan light, and is used to drive airflow to achieve the fan function.

[0069] In this disclosure embodiment, see Figure 2 The fan blade assembly 5 includes a fan blade disk 51 and a plurality of fan blades 52.

[0070] The fan blade disk 51 is a disc-shaped structure with a mounting hole in the middle. The fan blade disk 51 is sleeved on the shaft 1 through the mounting hole and can rotate around the shaft 1 under the drive of the annular magnet 311.

[0071] See also Figure 2Multiple fan blades 52 are arranged on the side of the fan blade disk 51 away from the lighting component 4 and are spaced apart along the circumference of the fan blade disk 51 to ensure dynamic balance and airflow uniformity, and reduce noise and vibration.

[0072] As the fan blades 52 rotate with the fan blade disk 51, they unfold under the action of centrifugal force and push air to achieve the air delivery function. At the same time, since the multiple fan blades 52 are located on the side of the fan blade disk 51 away from the lighting component 4, the fan blades 52 do not interfere with the lighting component 4 in the axial direction, and the multiple fan blades 52 do not block the lighting component 4, thus ensuring the lighting effect of the lighting component 4.

[0073] The annular magnet 311 is fixedly connected to the side of the fan blade disk 51 facing the lighting component 4, and is axially spaced relative to the stator component 2 fixed on the lamp disk 41 to form a disc motor.

[0074] In addition to the above structure, to improve the rotational stability of the fan blade assembly 5 relative to the shaft 1 and make the fan light operate more stably, see [link to relevant documentation]. Figure 4 and Figure 5 The fan light provided in this embodiment also includes a bearing 6.

[0075] The bearing 6 is ring-shaped and is fixedly sleeved on the shaft 1. The outer wall of the bearing 6 is fixedly connected to the fan blade disk 51. In this way, the fan blade disk 51 can rotate smoothly around the shaft 1 through the bearing 6, which helps to reduce friction and vibration.

[0076] For example, the bearing 6 can be a rolling bearing or an oil-impregnated bearing, and the bearing 6 includes an inner ring and an outer ring. The inner ring of the bearing 6 is sleeved on the shaft 1, and the outer ring is interference-fitted with the mounting hole of the fan blade disk 51.

[0077] See also Figure 4 and Figure 5 The fan light provided in this embodiment also includes a controller 8, which is used to control the power supply to and from the stator assembly 2 and the lamp strip.

[0078] The controller 8 can be in the form of a circuit board, which is equipped with electronic components such as a driver chip, rectifier bridge, and capacitors. It is used for current-voltage conversion and receiving control signals to realize control functions such as dimming and speed adjustment of the fan light.

[0079] See Figure 4 The controller 8 is fixedly connected to the side of the lamp panel 41 away from the fan blade assembly 5, and the lamp strip 42 is arranged around the outer periphery of the controller 8, so that the controller 8 and the lamp strip 42 are located on the same side of the lamp panel 41, which facilitates the electrical connection between the controller 8 and the lamp strip 42.

[0080] See Figure 8The lamp panel 41 has a wiring hole 414 through which the controller 8 is electrically connected to the stator assembly 2 and the lamp strip 42. Exemplarily, the lead wire of the controller 8 can pass through the wiring hole 414 from the back of the lamp panel 41 to the front of the lamp panel 41, and then be soldered or plugged into the lead wire of the coil 21 of the stator assembly 2; simultaneously, the lighting output terminal of the controller 8 is directly connected to the power input terminal of the lamp strip 42. This simplifies the wiring inside the fan light, avoids exposed cables, and improves the reliability and aesthetics of the fan light.

[0081] In one possible implementation, the fan light provided in this embodiment can simultaneously achieve lighting and air supply functions, or it can achieve lighting and air supply functions separately. The specific implementation principle is as follows: The controller 8 energizes the coil 21 of the stator assembly 2, generating an axial rotating magnetic field on the axial surface 221 of the stator core 22. The annular magnet 311 of the rotor assembly 3 is subjected to electromagnetic torque in the rotating magnetic field, which drives the fan blade disk 51 to rotate around the shaft 1. Multiple fan blades 52 promote air flow and realize the air supply function. The controller 8 supplies power to the light strip 42 through the outlet hole 414, and the light strip 42 emits light to achieve the lighting function.
