[0002] Fan lights, as a household appliance that integrates lighting and ventilation functions, are widely used in modern homes. Traditional fan light suspension systems typically employ a split design, requiring an additional suspension head component to connect the motor and the mounting plate. This design has significant technical drawbacks. During installation, operators need to perform extra steps to install the suspension head component, making the installation process cumbersome. Furthermore, current suspension systems require high precision in their components, necessitating multiple alignment adjustments during assembly. Adding extra steps further increases the difficulty of assembly, potentially leading to assembly errors and reduced connection stability.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0033] In existing technologies, fan lights, as electrical appliances that combine lighting and ventilation functions, generally adopt a split-structure design for their suspension systems. Traditional solutions require a separate suspension head component to connect the motor and the mounting plate, resulting in a large number of parts and complex assembly steps.

[0034] Please refer to Figure 1 and Figure 2 This utility model proposes a suspension structure 100 and a fan light. The suspension structure 100 includes a fixed plate 1 and a motor 2. The fixed plate 1 includes a base 11 and a connecting part 12 connected to the bottom of the base 11. The connecting part 12 forms a through hole 121, which is opened at the bottom end of the connecting part 12. The motor 2 has a connecting shaft 21, which extends into the through hole 121 and is fixed to the through hole 121.

[0035] The fixed plate can be made of metal casting or injection molded from engineering plastics. The connecting part 12 refers to the columnar structure extending from the bottom of the base 11, which can be designed as a cylinder or prism, to accommodate the connecting shaft 21 of the motor 2. The through hole 121 refers to a channel penetrating along the axial direction of the connecting part 12, which can be machined as a through hole or a blind hole. The base 11 and the connecting part 12 form an integral structure, with its inner diameter matching the outer diameter of the connecting shaft 21. The connecting shaft 21 of the motor 2 refers to the rotating shaft that drives the fan.

[0036] Specifically, the base 11 and the connecting part 12 form an integrated structure, eliminating the assembly steps of traditional lifting head components. The motor 2 connecting shaft 21 is directly inserted into the through hole 121 at the bottom of the connecting part 12 and fixed thereto. The fixing method can be screw fixing, thread fixing, or nut fixing, etc. This simplifies the installation steps of the motor and the mounting plate and improves connection stability.

[0037] Based on the above embodiments, the connecting portion also has a connecting hole 122, which is located on the side wall of the connecting portion 12 and communicates with the through hole 121. The suspension structure also includes a first connector 3, which passes through the connecting hole 122 and fixes the connecting shaft 21 and the connecting portion 12. In this embodiment, the first connector 3 refers to a fastening element that realizes a mechanical connection, specifically a bolt, pin, or rivet, used to laterally lock the connecting shaft 21 and the connecting portion 12. The connecting hole 122 laterally penetrates the side wall of the connecting portion 12 and communicates with the through hole 121, and the first connector 3 passes through the connecting hole 122 and abuts against the outer wall of the connecting shaft 21. The tight fit between the through hole 121 and the connecting shaft 21 ensures vertical installation accuracy, and the lateral force applied by the first connector 3 forms a three-point fixing effect. This combined fixing method simplifies the assembly process and enhances the torsional resistance of the connecting portion 12.

[0038] In one embodiment, please refer to Figure 3 The through hole 121 vertically penetrates the connecting part 12 and the base 11. The top end of the connecting shaft 21 is exposed through the through hole 121. The suspension structure 100 also includes a second connecting member 6, which is sleeved on the top end of the connecting shaft 21 and abuts against the base 11. In this embodiment, the through hole 121 can vertically penetrate the connecting part 12 and the base 11 so that the connecting shaft 21 extends into the through hole 121 from the bottom and the top end of the connecting shaft 21 can extend out of the through hole 121. The second connecting member 6 can be a fastening nut. By sleeved and fixed on the top end of the connecting shaft 21, the second connecting member 6 abuts against the base 11, thereby fixing the connecting shaft 21 to the fixed plate 1.

[0039] Compared to existing technologies, traditional split-type lifting heads require separate machining of the lifting head components and assembly onto the fixed plate 1. This solution integrates the connecting part 12 with the base 11, reducing the number of independent parts. In existing technologies, the motor 2 shaft needs to be installed onto the lifting head before connecting to the fixed plate 1. This solution directly positions the connecting shaft 21 via the through hole 121, eliminating intermediate assembly steps. Traditional structures rely on a single bolt for locking; this solution uses the through hole 121 for positioning and locking with the first connecting piece 3, forming a double constraint and improving connection stability.

[0040] Through the above technical solutions, this application reduces the number of parts in the suspension structure 100, thereby lowering processing and assembly costs. The mating positioning of the connecting shaft 21 and the through hole 121 simplifies the assembly process and avoids multiple alignment adjustments. The synergistic effect of the transverse first connecting piece 3 and the axial through hole 121 enhances the connection rigidity, effectively preventing loosening during long-term use. The overall structural design significantly improves assembly efficiency and product stability while ensuring reliability.

[0041] In one embodiment, the groove 123 formed by the inward recess of the sidewall refers to a recessed structure formed on the sidewall of the connecting part 12 by stamping or cutting, specifically by mold forming or machining. The bottom wall thickness of this recessed structure is less than the original sidewall thickness of the connecting part 12, so that the position of the connecting hole 122 is naturally defined by the bottom wall of the groove 123. The connecting hole 122 formed by the bottom wall of the groove 123 refers to a hole penetrating the bottom wall of the groove 123, specifically by drilling or milling. The axis of this hole forms a perpendicular or inclined angle with the axis of the connecting part 12, for accommodating the first connecting member 3 to pass through for fixation.

[0042] Specifically, when the groove 123 is machined on the side wall of the connecting part 12, the flatness of the bottom wall of the groove 123 is directly controlled by the mold forming, without the need for separate positioning of the connecting hole 122. When the first connecting member 3 passes through the connecting hole 122 on the bottom wall of the groove 123, the two side walls of the groove 123 form a wrapping structure for the first connecting member 3, restricting the displacement of the first connecting member 3 in the radial direction. At the same time, the groove 123 structure also shortens the effective thickness of the side wall of the connecting part 12, so that the first connecting member 3 only needs to pass through the bottom wall of the groove 123 to be fixed, significantly shortening the axial length of the first connecting member 3.

[0043] Through the above technical solutions, this application reduces the machining accuracy requirements of the connecting hole 122 and eliminates the impact of the flatness error of the bottom wall of the groove 123 on assembly. The contact area between the first connecting member 3 and the side wall of the groove 123 is increased, and the vibration energy generated when the motor 2 is running is absorbed by the structure of the groove 123, avoiding relative displacement between the connecting shaft 21 and the connecting part 12. The axial length of the first connecting member 3 is shortened, reducing material costs and reducing the risk of interference caused by the excessive length of the first connecting member 3 during assembly.

[0044] In one embodiment, there are two grooves 123, which are symmetrically arranged on both sides of the connecting part 12. Symmetrical arrangement means that the two grooves 123 are mirror images of each other with respect to the central axis of the connecting part 12. This can be achieved by using a positioning fixture to ensure machining positional accuracy. This symmetrical structure allows the first connecting member 3 to form balanced force support on both sides, eliminating the eccentric torque caused by fixing on one side.

[0045] Specifically, when the connecting shaft 21 extends into the through hole 121, the two first connecting pieces 3 are inserted into the connecting holes 122 opened in the bottom walls of the side grooves 123, respectively, to fix the connecting shaft 21 and the connecting part 12 in both directions. The symmetrical fixing method on both sides creates a double constraint on the connecting shaft 21 in the circumferential direction, avoiding axial displacement caused by single-point fixing. The first connecting pieces 3 can be screws or bolts. When using screws, they are directly driven into the connecting shaft 21; when using bolts, a threaded structure is provided in the connecting hole 122 to achieve fastening.

[0046] In one embodiment, please refer to Figure 4 and Figure 5 An internal thread is formed within the through hole 121, and an external thread matching the internal thread is formed on the outer wall of the top end of the connecting shaft 21. The connecting shaft 21 extends into the through hole 121 and is threadedly connected to it. The internal thread refers to a helical groove machined on the inner wall of the through hole 121, and its pitch and direction of rotation must strictly correspond to the external thread. The external thread is formed on the outer wall of the connecting shaft 21, specifically through turning or rolling processes at the shaft end, and its geometric parameters form a clearance fit with the internal thread. A threaded connection is a mechanical connection method that generates axial preload through the engagement of internal and external threads; its helix angle design must meet self-locking conditions.

[0047] Specifically, when the external thread of the connecting shaft 21 is screwed into the internal thread of the through hole 121, the inclined contact of the threaded pair generates an axial component force, pressing the connecting shaft 21 and the connecting part 12 together to form a rigid connection. The continuous meshing of the thread profiles ensures that the load is evenly distributed along the helix, avoiding stress concentration. During assembly, only rotating the connecting shaft 21 is needed to complete axial positioning and circumferential fixing, without the need for auxiliary positioning fixtures. The self-locking characteristic of the threaded pair prevents the connection from loosening under vibration, and the frictional torque generated by the preload can resist lateral loads.

[0048] Through the above technical solution, this application achieves a rigid connection between the connecting shaft 21 and the fixed disk 1, eliminating the stress concentration phenomenon caused by discontinuous contact surfaces in traditional structures. The assembly process eliminates the need for repeated alignment adjustments, effectively reducing operational complexity. The preload and self-locking effect of the threaded pair maintain connection stability over a long period, preventing loosening or displacement during use, thereby improving the safety and reliability of the fan light during operation.

[0049] In one embodiment, the connecting shaft 21 includes a first connecting segment 211 and a second connecting segment 212 that are connected to each other. The first connecting segment 211 connects the second connecting segment 212 and the motor 2. The first connecting segment 211 has a through hole 213, and the outer wall of the second connecting segment 212 has an external thread. The through hole 213 is used for external tools to be inserted.

[0050] Please refer to Figure 1 and Figure 6Specifically, the through hole 213 refers to the axial channel penetrating the first connecting section 211. It can be circular or hexagonal. External tools such as screwdrivers or wrenches can pass through the through hole 213. During assembly, the external tool passes through the through hole 213 of the first connecting section 211. Rotating the external tool drives the second connecting section 212 to rotate along the thread direction. When torque is applied by the tool, the external thread of the second connecting section 212 and the internal thread of the connecting hole 122 generate a helical pushing action until they reach the preset tightening depth. In this process, the first connecting section 211 not only transmits the load of the motor 2 but also provides the necessary axial channel for tool operation.

[0051] In other embodiments, please refer to Figure 2 The through hole 213 can also serve as the insertion hole for the first connector 3. Specifically, the first connector 3 passes through the connecting hole 122 and the through hole 213 in sequence and fixes the connecting shaft 21 and the connecting part 12. After the connecting shaft 21 is vertically inserted into the through hole 121, the operator can insert the connector laterally into the connecting hole 122 and the through hole 213, thereby simultaneously constraining axial displacement and radial rotation. The connection design between the connecting hole 122 and the through hole 121 allows the connector to be directly inserted from the side, forming a three-point contact fixing method.

[0052] Through the above technical solution, this application achieves high-precision thread assembly within a limited space, solving the problem of loose thread fit caused by insufficient operating space in traditional assembly methods. External tools can be directly applied to the end face of the second connecting section 212 through the through hole 213, ensuring that the threaded connection reaches the predetermined torque value, while avoiding thread stripping or insufficient preload caused by manual operation.

[0053] In one embodiment, this application further proposes that the length of the second connecting segment 212 matches the depth of the through hole 121. Specifically, when the second connecting segment 212 is fully screwed into the through hole 121, the engagement length of the external thread and the internal thread reaches its maximum value. At this time, the thread contact surface is evenly distributed along the axial direction, avoiding thread deformation or stripping caused by local stress concentration. During assembly, the operator only needs to screw the second connecting segment 212 into the bottom of the through hole 121 to automatically achieve precise control of the thread engagement length without the need for depth measurement or repeated adjustments.

[0054] Through the above technical solution, this application achieves precise control of the axial dimension of the threaded connection, effectively preventing the connection loosening problem caused by insufficient meshing length, while simplifying the assembly operation process and improving the reliability of the connection structure.

[0055] In one embodiment, a transition fillet 4 is formed at the connection between the two side walls of the groove 123 and the outer wall of the connecting part 12. The transition fillet 4 refers to the arc-shaped structure formed at the connection between the side walls of the groove 123 and the outer wall of the connecting part 12. Specifically, when machining the groove 123 on the side wall of the connecting part 12, the right-angle connection between the two side walls of the groove 123 and the outer wall of the connecting part 12 is changed to an arc transition, transforming the geometry of this area from sharp angles to a continuous curved surface. This arc structure allows stress to be evenly distributed along the curved surface at the connection, reducing stress concentration caused by abrupt right-angle changes. Simultaneously, the arc transition also reduces the risk of rigid collisions or scratches between the edges of the groove 123 and other components during assembly, thereby improving structural reliability. Through the above technical solution, this application effectively eliminates the stress concentration problem at the connection between the groove 123 and the outer wall of the connecting part 12, enhancing the overall mechanical strength of the suspension structure 100. The arc transition design avoids localized material fatigue caused by right-angle connections, extends the service life of components, and reduces the risk of component damage caused by sharp angles during assembly, improving product assembly efficiency and reliability.

[0056] In one embodiment, the connecting portion 12 is columnar, and a stepped surface 5 is formed at the connection between the connecting portion 12 and the base 11. The columnar connecting portion 12 refers to a component with a cylindrical or prismatic geometric shape, which can be achieved through metal casting or injection molding. Its axial extension direction is consistent with the installation direction of the connecting shaft 21 of the motor 2. The columnar structure can improve the bending strength of the connecting portion 12 in the vertical direction. The stepped surface 5 refers to an annular planar structure formed at the junction of the base 11 and the connecting portion 12. It can be achieved through a stepped processing method. The radial dimension of the stepped surface 5 is larger than the outer diameter of the connecting portion 12, thus limiting the contact area between the connecting portion 12 and the base 11 and achieving axial positioning. Specifically, the columnar connecting portion 12 bears the load of the motor 2 and the fan lamp through its uniformly distributed cross-sectional shape, avoiding the risk of deformation caused by local stress concentration. The stepped surface 5 serves as a reference surface during assembly, ensuring that the central axis of the connecting part 12 and the base 11 is aligned, thus guaranteeing the coaxiality of the connecting hole 122 and the through hole 211 and reducing the fitting error caused by axis offset during installation.

[0057] In one embodiment, the base 11 and the connecting part 12 are integrally formed. Specifically, when the base 11 and the connecting part 12 are manufactured using an integral forming process, their geometry and relative positions are directly controlled by the mold. Since it is not necessary to process the base 11 and the connecting part 12 separately before assembly, the cumulative dimensional errors caused by separate manufacturing in a split structure are avoided. During the forming process, the connection between the base 11 and the connecting part 12 forms a seamless structure through continuous material distribution, thereby ensuring that the positional accuracy of key features such as the through hole 121 and the connecting hole 122 is guaranteed by the mold in one step. Therefore, the motor 2 connecting shaft 21 can directly and precisely fit with the through hole 121 during installation, without the need for repeated adjustments to compensate for assembly deviations between the base 11 and the connecting part 12.

[0058] This utility model also proposes a fan light, which utilizes the aforementioned suspension structure 100. Since this fan light employs all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.
