Ceiling Fan Light

Abstract

In the ceiling fan light provided by the present application, each fan blade is interconnected through a synchronization mechanism. The chute on the synchronization ring is "V"-shaped. This chute shape causes the synchronization ring to have different selection directions in the two chutes with different angles of the "V" shape when the fan blades are opened, which can avoid interference with the roots of the fan blades and achieve large-angle rotation of the fan blades, thereby generating a better air outlet effect.

Description

Technical Field

[0001] The present invention relates to the technical field of fan lights, and particularly to a fan light with an improved structure. Background Art

[0002] The blades of a hidden fan light can be retracted. Usually, when not in use, the blades are hidden above the light, and when in use, the blades are deployed. The hidden fan has multiple blades. To ensure the normal use of the product, the blades need to be synchronized when deploying and closing. Therefore, basically all related products on the market now have a synchronization structure. In the existing design, multiple blades are connected to each other through a synchronization ring, so that each blade rotates synchronously. The synchronization ring is usually a circular ring. When setting the synchronization ring, in order to prevent the synchronization ring from affecting the rotation of the blades, the size of the synchronization ring is restricted, and this restriction affects the deployment amplitude of the blades, thereby affecting the air volume.

[0003] Therefore, it is desired that there is a hidden fan that can overcome or at least mitigate the above-mentioned defects of the prior art and can obtain a larger deployment angle during synchronization control. Summary of the Invention

[0004] The object of the present invention is to solve the problems of small blade deployment angle and poor air outlet effect of the existing fan lights, and to provide a fan light with a novel synchronization structure.

[0005] To achieve the above object, the technical solution adopted by the present invention is to provide a fan light, including a mounting base, a suspension rod, a fan assembly, and a lamp assembly. The mounting base is fixedly installed on a mounting foundation, the suspension rod is connected to the mounting base, and the fan assembly and the lamp assembly are arranged on the suspension rod. It is characterized in that: the fan assembly includes a motor, multiple blades, and a carrier plate for carrying the blades. The carrier plate is connected to the motor, and the motor can drive the carrier plate to rotate. Each blade is rotatably installed on the carrier plate, and the blade unfolds as the carrier plate rotates. The fan assembly further includes a synchronization mechanism. The synchronization mechanism includes a synchronization ring that is coaxial with the carrier plate and can rotate relative to the carrier plate. The synchronization ring is provided with a chute equal in number to the blades; a slider provided on the blade and cooperating with the chute. When the slider slides in the chute, the synchronization ring rotates relative to the carrier plate.

[0006] The chute includes a first groove section and a second groove section. When the slider travels in the same direction in the chute, the rotation direction of the synchronization ring when the slider slides in the first groove section is opposite to the rotation direction of the synchronization ring when the slider slides in the second groove section.

[0007] Preferably, one end of the chute is a converging end. When the slider is located at the converging end, the fan blade coincides with the bearing plate in the vertical direction. The other end of the chute is a deploying end. When the slider is located at the deploying end, the fan blade is deployed to the maximum angle. The first groove section has a first end and a second end, and its first end is the converging end. The second groove section has a first end and a second end, and its first end is the deploying end.

[0008] Preferably, the second end of the first groove section and the second end of the second groove section are connected to each other.

[0009] Preferably, a transition groove section is further connected between the second end of the first groove section and the second end of the second groove section.

[0010] Preferably, the chute is in a "V" shape, and the opening of the "V" shape faces the outside of the synchronous ring.

[0011] Preferably, the first groove section and the second groove section are straight lines or curves.

When the fan blade is deployed, the free end extends out of the bearing plate, and the slider rotates following the connecting arm.

[0013] Preferably, when the slider is located in the first groove section, the rotation direction of the slider is the same as the rotation direction of the synchronous ring. When the slider is located in the second groove section, the rotation direction of the slider is opposite to the rotation direction of the synchronous ring.

[0014] Preferably, the distance from the outermost side of the synchronous ring to the suspension rod is greater than the distance from the mounting end of the fan blade to the suspension rod. The synchronous ring has an avoidance space at the "V" - shaped notch, and the mounting end of the fan blade is located in the avoidance space.

[0015] Preferably, the synchronization mechanism further includes a fixed disk. The main body of the fixed disk is in a hollow cylindrical shape. The inner cavity of the synchronous ring is circular and is coaxially arranged with the fixed disk. The synchronous ring is sleeved outside the fixed disk.

[0016] Preferably, the synchronous ring includes a stacked metal plate layer and a rubber - coated plastic layer.

[0026] The following further describes in detail the ceiling fan provided by the present invention with reference to the accompanying drawings and specific embodiments.

[0027] Figure 2 shows a ceiling fan light according to a preferred embodiment of the present application. Its exploded view is as Figure 1 shown. The ceiling fan light includes a mounting base 4, a suspension rod 3, a fan assembly 2, and a lamp assembly 1. The mounting base 4 is fixedly installed on a ceiling, roof beam, or other installation foundation. One end of the suspension rod 3 is connected to the mounting base 4, and the other end is connected to the lamp assembly 1 and the fan assembly 2. In this embodiment, the suspension rod 3 is threadedly connected to the fixed shaft of the motor 23 in the fan assembly 2, and the lamp assembly 1 is connected to the lower end of the fixed shaft. The fixed shaft is an extension of the suspension rod 3. In other preferred embodiments, the lamp assembly 1 and the fan assembly 2 can also be arranged at different positions on the suspension rod according to the styling requirements. For example, the lamp assembly 1 can be arranged above the fan assembly 4, or the lamp assembly 1 can be arranged around the fan assembly 4 through a bracket, etc. The present application does not limit this.

[0028] The fan assembly includes a motor 23, a plurality of fan blades 21, and a carrier plate 27 for carrying the fan blades 21. The carrier plate 27 is connected to the motor 23 and can be driven by the motor 23 to rotate. The specific structure of the fan blade 21 is as shown in Figure 5 which includes a mounting end 2101 and a free end 2102. The fan blade 21 is rotatably mounted on the carrier plate 27 through the mounting end 2101. In this embodiment, a through hole is provided at the mounting end 2102, and a screw passes through the through hole to mount the fan blade 21 onto the carrier plate 27. The free end 2102 can rotate from the closed position to the unfolded position with the screw as the rotation axis. In the non-working state, the fan blade 21 is in the closed position as shown in Figure 2 where all the fan blades 21 are hidden behind the lamp panel. When the fan starts to work, the motor 23 drives the carrier plate 27 to rotate, and the fan blades 21 provided on the carrier plate 27 rotate accordingly and unfold outward due to inertia. The state after unfolding is as shown in Figure 3 When the fan stops working, the fan blades 21 need to be folded back. Therefore, a reset structure is further included. The reset structure is provided at the connection between the fan blade 21 and the carrier plate 27. In this embodiment, the reset structure is a torsion spring 22, and the torsion spring 22 can keep the fan blade 21 in the folded state when the carrier plate 27 is stationary.

[0029] Generally, a fan has a plurality of fan blades. To ensure the normal use of the product, the fan blades 21 need to be synchronized when unfolding and folding. Therefore, the fan assembly 2 further includes a synchronization mechanism, which includes a fixed disk 26, a synchronization ring 24, and a connecting rod 25. The fixed disk 26 is fixedly connected to the carrier plate 27. In this embodiment, the fixed disk 26 and the carrier plate 27 are two separate components. In other preferred embodiments, the fixed disk 26 and the carrier plate 27 can also be integrally formed. The main body of the fixed disk 26 is in the shape of a hollow cylinder, and the inner cavity of the synchronization ring 24 is circular as shown in Figure 4 and is coaxially arranged with the fixed disk 26. The fixed disk 26 and the synchronization ring 24 can be connected by a buckle. The synchronization ring 24 is sleeved outside the main body of the fixed disk 26, and the buckle is used to prevent it from coming off. The synchronization ring 24 can rotate relative to the fixed disk 26 to form a rotational connection.

[0030] The function of the synchronization ring 24 is to synchronize the expansion angles of each blade 21, so it must be connected to each blade 21. The connecting arm 2103 on the blade 21 extends from the mounting end 2101 in a direction different from the extension direction of the blade body, and a slider 2104 is provided on the connecting arm 2103. When the blade 21 is expanded, the free end 2102 extends out of the carrier plate 27, and the slider 2104 rotates with the connecting arm 2103. In the present application, synchronization is achieved by providing a slide groove 2401 that cooperates with the slider 2104 on the synchronization ring 24, and each blade 21 corresponds to a slide groove 2401, so the number of slide grooves is the same as the number of blades 21. When the blade 21 is opened, the slider 2104 rotates, and the synchronization ring 24 is driven to rotate relative to the carrier plate 27 by its sliding in the slide groove 2401. The shapes and positions of the slide grooves 2401 are the same, which ensures that the opening angles of the blades 21 remain synchronized.

[0031] The synchronization ring 24 and the fan blades 21 are both arranged on the carrier plate 27. In the previous design, in order to prevent the synchronization ring 24 from interfering with the installation end 2101 of the fan blade 21, the outer side of the synchronization ring needs to be smaller than the distance from the center of the carrier plate 27 to the installation end 2101 of the fan blade 21, so as to prevent the synchronization ring 24 from hitting the fan blade 21 during rotation. However, in this design, the size of the synchronization ring 24 is limited, so that the length of the slide groove 2401 is also limited, and the fan blade 21 cannot be expanded to a sufficient angle, which affects the air volume. To solve this problem, the present application improves the form of the slide groove 2401, such as Figure 4 As shown, the slide groove 2401 is in a "V" shape, and its opening faces the outside of the synchronization ring. The two sides of the "V" shape are respectively the first groove section 2404 and the second groove section 2405, and the first groove section 2404 and the second groove section 2405 can be a straight line or a curve. The two endpoints of the "V"-shaped slide groove 2401 are respectively the folded end 2402 and the unfolded end 2403. When the slider 2104 is located at the folded end 2402, the fan blade 21 is in a folded state, and it overlaps with the carrier plate 27 in the vertical direction. When the slider 2104 is at the unfolded end 2403, the fan blade 21 is unfolded to the maximum angle. The first end of the first groove section 2404 is the folded end 2402, the first end of the second groove section 2405 is the unfolded end 2403, and the second ends of the first groove section 2404 and the second groove section 2405 are connected to each other. In other preferred embodiments, the second ends of the first groove section 2404 and the second groove section 2405 may not be directly connected, and a transition groove section may be provided between the two. The transition groove section may be an arc section, so that the sliding process of the slider 2104 can be smoother.

[0032] Using this "V" shaped slide, such as Figure 6aAs shown, the distance L2 from the outermost side of the synchronous ring 24 to the suspension rod 3 can be designed to be greater than the distance L1 from the mounting end 2101 of the fan blade 21 to the suspension rod 3. At the same time, the synchronous ring 24 has an avoidance space 2408 at the "V"-shaped notch, and the mounting end 2101 of the fan blade 21 is located in the avoidance space 2408. And during the unfolding process of the fan blade 21, although the synchronous ring 24 will rotate, the mounting end 2101 is always in the avoidance space 2408 and will not interfere with the mounting end 2101. The principle is that when the slider 2104 travels in the same direction in the chute 2401, the rotation direction of the synchronous ring 24 when the slider 2104 slides in the first chute section 2404 is opposite to the rotation direction of the synchronous ring 24 when the slider 2104 slides in the second chute section 2405.

[0033] Next, we will use Figures 6a - 6e to illustrate the problem of this rotation direction. For the convenience of seeing the synchronous ring 24 clearly, in the figure, we only take one fan blade 21 as an example schematically. In Figure 6a , the fan blade 21 is in the retracted state, the slider 2104 is at the retracted end 2402 of the chute 2401, and the fan blade 21 will rotate counterclockwise in the rotation direction A and enter Figure 6b state. In Figure 6b , the slider 2104 slides in the first chute section 2404, the fan blade 21 rotates counterclockwise in the rotation direction A, the synchronous disk 24 rotates counterclockwise in the rotation direction B, and the rotation direction of the slider 2104 is the same as the rotation direction of the synchronous ring 24 until it reaches Figure 6c position, the first chute section 2404 ends, and the second chute section 2405 is about to start. In Figure 6d , the slider 2104 continues to rotate with the fan blade 21 and slides in the second chute section 2405. The fan blade 21 rotates counterclockwise in the rotation direction A, the synchronous disk 24 rotates clockwise in the rotation direction C, and the rotation direction of the slider 2104 is opposite to the rotation direction of the synchronous ring 24. Finally, the slider 2104 travels to the unfolded end 2403 of the chute 2401. As shown in Figure 6e , the fan blade 21 is opened to the maximum angle. From Figures 6a through 6e of the entire unfolding process, the mounting end 2101 of the fan blade 21 is always in the avoidance space 2408 position of the "V"-shaped chute, and the fan blade 21 and the synchronous ring 24 do not interfere with each other.

[0034] Figure 1 The embodiment is a three-blade ceiling fan light, and the solution proposed in this application is also applicable to various other types of ceiling fan lights. Figures 7a - 7e shows a process diagram of the unfolding of the fan blade in another preferred embodiment of the ceiling fan light of this application. This embodiment is a four-blade ceiling fan, and its specific structure is similar to that of Figure 1 embodiment, so it will not be elaborated here. From Figures 7a - 7eIt can be seen that it adopts a "V"-shaped chute design, which also realizes the function of different rotation directions of the synchronous rings in the two chute segments, thereby enabling a larger unfolding amplitude of the fan blades and better wind effects.

[0035] The synchronous ring 24 can be made of materials such as metal or plastic. In the above preferred embodiment, the synchronous ring 24 includes a stacked metal plate layer and a plastic layer with rubber coating, and the in-mold injection process is used to improve the flatness and strength of the synchronous disk 24.

[0036] The above description of the preferred embodiments of the present application is for illustration and description purposes, and is not intended to exhaust or limit the present application to the specific forms disclosed. Obviously, many modifications and variations are possible, and these modifications and variations may be obvious to those skilled in the art and should be included within the scope of the present application defined by the appended claims.
