Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a fan light. Background Art

[0002] A fan light is a device that combines lighting and fan functions. For aesthetics and to reduce dust accumulation on the fan blades, the fan blades of the fan light are configured to be rotatable relative to the fan blade disc. When the fan function is needed, the fan blades rotate relative to the fan blade disc under the action of centrifugal force and extend out of the fan blade disc. When the fan function is not needed, the fan blades rotate relative to the fan blade disc in the opposite direction under the action of the elastic resetting member and fold back onto the fan blade disc.

[0003] To ensure the realization of the opening and closing function of the fan blades, installation points for installing the elastic resetting member are usually provided on the fan blade disc. At the same time, to ensure that the fan blades do not interfere with other components of the fan light when rotating on the fan blade disc, a limiting structure for limiting the rotation angle of the fan blades needs to be provided on the fan blade disc, resulting in a relatively large number of structures on the fan blade disc. It is easy for these structures to interfere with each other and difficult to layout, increasing the processing difficulty and cost of the fan light. Summary of the Utility Model

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the utility model provides a fan light.

[0005] The utility model provides a fan light, comprising:

[0006] A fan blade disc;

[0008] A driving member, connected to the fan blade disc and configured to drive the fan blade disc to rotate and drive the fan blades to unfold relative to the fan blade disc;

[0009] A limiting protrusion is formed on the surface of the fan blade disc facing the fan blades, and a limiting notch is formed on the end face of the installation post facing the fan blade disc.

[0011] The fan light provided by the utility model forms a mounting post at one end of the fan blade. The mounting post is rotatably connected to the fan blade disc. A limiting notch is provided on the mounting post. The limiting protrusion and the limiting notch are in limiting cooperation to limit the rotation angle of the mounting post relative to the fan blade disc, thereby restricting the rotation angle of the fan blade relative to the fan blade disc.

When the fan blade needs to be unfolded, the driving member is used to drive the fan blade disc to rotate, and the fan blade is driven to unfold relative to the fan blade disc. When the fan blade needs to be folded, the elastic reset member is used to drive the fan blade to rotate relative to the fan blade disc and reset to fold the fan blade, thus ensuring the realization of the opening and closing function of the fan blade. With such a setting, the limiting protrusion can not only be used to connect the elastic reset member but also be used to cooperate with the limiting notch on the mounting post to limit the rotation angle of the fan blade relative to the fan blade disc. Without additionally setting a limiting structure on the fan blade disc, the fan blade can rotate relative to the fan blade disc within a certain range, and the fan blade automatically resets under the drive of the elastic reset member, simplifying the structure on the fan blade disc, reducing the difficulty of setting a limiting structure between the fan blade and the fan blade disc, and reducing the manufacturing cost of the fan light.

[0014] In some embodiments, a receiving groove is formed by the surface of the mounting post facing the fan blade disc being recessed, and the limiting notch is formed on the side of the groove wall of the receiving groove facing the fan blade disc.

[0015] The elastic reset member is a reset torsion spring. The reset torsion spring is located in the receiving groove, and one end of the reset torsion spring is connected to the inner wall of the receiving groove.

One end of the reset torsion spring is inserted and connected to the connecting groove.

[0017] In some embodiments, an installation gap is formed between the side of the mounting post facing the fan blade disc and the fan blade disc.

[0018] The reset torsion spring includes a torsion spring body arranged in a spiral shape and two torsion feet connected to both end portions of the torsion spring body.

Detailed implementation manners

[0037] In order to more clearly understand the above objects, features and advantages of the present invention, the following will further describe the solution of the present invention. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0039] Referring to Figures 1 to 8 As shown, an embodiment of the present utility model provides a fan lamp, which includes a fan blade disc 1, fan blades 21, a driving member 5, and an elastic reset member 3.

[0040] Among them, the fan blades 21 are arranged on the fan blade disc 1. One end of the fan blade 21 is formed with a mounting post 22, and the mounting post 22 is rotatably connected to the fan blade disc 1. The driving member 5 is connected to the fan blade disc 1 and is configured to drive the fan blade disc 1 to rotate and drive the fan blades 21 to unfold relative to the fan blade disc 1 so as to unfold the fan blades 21. Specifically, the driving member 5 drives the fan blade disc 1 to rotate. During the rotation of the fan blade disc 1, a centrifugal force is generated. The fan blades 21 will rotate relative to the fan blade disc 1 under the action of the centrifugal force, that is, the fan blades 21 will be thrown out in a direction away from the center of the fan blade disc 1 under the action of the centrifugal force to unfold the fan blades 21. After the fan blades 21 unfold relative to the fan blade disc 1, during the continuous rotation of the fan blade disc 1, the fan blades 21 will remain in the unfolded state under the action of the centrifugal force and rotate synchronously with the fan blade disc 1.

[0041] A limiting protrusion 11 is formed on one side surface of the fan blade disc 1 facing the fan blades 21, and a limiting notch 23 is formed on one end surface of the mounting post 22 facing the fan blade disc 1. The limiting protrusion 11 is limited within the limiting notch 23 to limit the rotation angle of the fan blades 21 relative to the fan blade disc 1.

[0042] The elastic reset member 3 is connected between the mounting post 22 and the limiting protrusion 11 and is configured to drive the fan blades 21 to close relative to the fan blade disc 1 so as to close the fan blades 21. Specifically, during the rotation of the fan blade disc 1, the fan blades 21 rotate and unfold relative to the fan blade disc 1 under the action of the centrifugal force, causing the elastic reset member 3 connected between the fan blades 21 and the fan blade disc 1 to deform and store elastic potential energy. In this way, when the driving member 5 stops driving, that is, after the driving member 5 stops providing the rotation function to the fan blade disc 1, the fan blade disc 1 will gradually decelerate to a stop. The centrifugal force generated by the rotation of the fan blade disc 1 will gradually decrease to disappear. The elastic reset member 3 releases the elastic potential energy and returns to the state before deformation, so that the fan blades 21 rotate reversely relative to the fan blade disc 1 and reset under the elastic force of the elastic reset member 3, thereby realizing the function of driving the fan blades 21 to reset by using the elastic reset member 3, and making the fan blades 21 rotate relative to the fan blade disc 1 to the closed state.

[0043] Specifically, the fan blade disc 1 is of a disc structure, and the fan blade 21 is rotatably connected to the edge of the fan blade disc 1, so that the centrifugal force generated when the fan blade disc 1 rotates can act on the fan blade 21. One end of the fan blade 21 can be selected to be provided with a mounting post 22, and the mounting post 22 extends away from the fan blade 21 along a direction perpendicular to the extension direction of the fan blade 21. A threaded hole can be provided on the side surface of the mounting post 22 facing the fan blade disc 1, and a through hole is provided on the fan blade disc 1. A bolt is used to rotatably connect with the through hole on the fan blade disc 1, and the bolt is threadedly connected to the threaded hole on the mounting post 22, so that the mounting post 22 is rotatably connected to the fan blade disc 1 through the bolt. Of course, it can also be selected to provide a bearing on the side surface of the fan blade disc 1 facing the fan blade 21, and the mounting post 22 is connected to the bearing, so that the mounting post 22 is rotatably connected to the fan blade disc 1.

[0044] The above-mentioned driving member 5 can be selected as a motor or a rotating cylinder and other mechanisms. The driving member 5 can be selected to be connected to the center of the fan blade disc 1, so that the fan blade disc 1 is driven to rotate around its own central axis after the driving member 5 is started.

[0045] The above-mentioned limiting notch 23 can be selected as a groove formed by the depression of the side surface of the mounting post 22 facing the fan blade disc 1. The groove is an arc-shaped groove extending along the circumferential direction of the mounting post 22, so that the groove forms the limiting notch 23, and the limiting protrusion 11 moves between the two ends of the groove, thereby restricting the moving range of the limiting protrusion 11 relative to the limiting notch 23, so as to achieve the effect of restricting the rotation angle of the fan blade 21 relative to the fan blade disc 1.

[0046] Of course, it can be selected that the edge of the side surface of the mounting post 22 facing the fan blade disc 1 is recessed to form a groove, and the two ends of the groove along the circumferential direction of the mounting post 22 have inner walls that can abut against the limiting protrusion 11, so that the limiting protrusion 11 moves in the groove to limit the rotation angle of the fan blade 21 relative to the fan blade disc 1.

[0047] The above-mentioned elastic resetting member 3 can be selected as a long strip-shaped tension spring. The tension spring is arranged along the circumferential direction of the fan blade disc 1. One end of the tension spring is connected to the fan blade disc 1, and the other end is connected to the side surface of the mounting post 22. And the tension spring applies an elastic force that drives the fan blade 21 to rotate towards the direction close to the center of the fan blade disc 1 to the fan blade 21 during the unfolding and folding processes of the fan blade 21. Of course, the elastic resetting member 3 can also be selected as a torsion spring. The two ends of the torsion spring are respectively connected to the second side surface and the limiting protrusion 11. During the unfolding and folding processes of the fan blade 21, the torsion spring applies an elastic force that drives the fan blade 21 to rotate towards the direction close to the center of the fan blade disc 1 to the fan blade 21.

[0048] When the above-mentioned impeller disc 1 is stationary, the elastic reset member 3 causes the impeller 21 to rotate towards the center of the impeller disc 1, so that the impeller 21 closes on the impeller disc 1. At this time, the position where the impeller 21 is located is the closed position; when the impeller disc 1 rotates, the centrifugal force generated by the rotation of the impeller disc 1 causes the impeller 21 to rotate away from the center of the impeller disc 1, so that the impeller 21 rotates from the closed position to a position where it extends radially out of the impeller disc 1 on the impeller disc 1. At this time, the impeller 21 is in the unfolded position and unfolds on the impeller disc 1.

[0049] When the impeller 21 is in the unfolded position, the elastic reset member 3 is in a deformed state and stores elastic potential energy. When the driving member 5 stops driving, that is, after the driving member 5 stops providing the rotation function to the impeller disc 1, the impeller disc 1 will gradually decelerate to a stop. The elastic reset member 3 releases the elastic potential energy and returns to the state before deformation, so that the elastic reset member 3 drives the impeller 21 back to the closed position to complete the reset, so that the impeller 21 rotates relative to the impeller disc 1 to the closed state.

[0050] When the fan lamp provided by the embodiment of the present utility model is specifically used, the mounting column 22 is rotatably connected to the impeller disc 1. One end of the elastic reset member 3 is connected to the limiting protrusion 11, and the other end is connected to the mounting column 22. The limiting protrusion 11 is inserted into the limiting notch 23; the elastic force of the elastic reset member 3 drives the impeller 21 to close. When the impeller disc 1 is stationary, the elastic reset member 3 causes the impeller 21 to rotate towards the center of the impeller disc 1, so that the impeller 21 is kept in the closed position to make the impeller 21 close; when it is necessary to unfold the impeller 21, the driving member 5 is used to drive the impeller disc 1 to rotate. The centrifugal force generated by the rotation of the impeller disc 1 overcomes the elastic force of the elastic reset member 3, and causes the impeller 21 to rotate away from the center of the impeller disc 1, so that the impeller 21 unfolds on the impeller disc 1; when it is necessary to close the impeller 21, the driving member 5 stops working and the impeller disc 1 gradually stops from the rotation. The elastic reset member 3 drives the impeller 21 to rotate towards the center of the impeller disc 1, so that the impeller 21 gradually rotates towards the closed position, and finally the impeller 21 rotates to the closed position to complete the reset, so that the impeller 21 closes.

[0051] The ceiling fan light provided by the embodiment of the present utility model forms a mounting post 22 at one end of the fan blade 21 by arranging a limiting protrusion 11 on the fan blade disc 1. The mounting post 22 is rotatably connected to the fan blade disc 1, and a limiting notch 23 is arranged on the mounting post 22. The limiting protrusion 11 is in limiting cooperation with the limiting notch 23, so that the rotation angle of the mounting post 22 relative to the fan blade disc 1 is limited, and thus the rotation angle of the fan blade 21 relative to the fan blade disc 1 is limited. At the same time, an elastic resetting member 3 is connected between the mounting post 22 and the limiting protrusion 11. When the fan blade needs to be unfolded, the driving member 5 is used to drive the fan blade disc 1 to rotate, and drive the fan blade 21 to unfold relative to the fan blade disc 1 to unfold the fan blade 21. When the fan blade 21 needs to be folded, the elastic resetting member 3 is used to drive the fan blade 21 to rotate relative to the fan blade disc 1 and reset to fold the fan blade 21, so as to ensure the realization of the opening and closing function of the fan blade 21. With such a setting, the limiting protrusion 11 can not only be used to connect the elastic resetting member 3, but also be used to cooperate with the limiting notch 23 on the mounting post 22 to limit the rotation angle of the fan blade 21 relative to the fan blade disc 1. Without additionally arranging a limiting structure on the fan blade disc 1, the fan blade 21 can rotate relative to the fan blade disc 1 within a certain range, and the fan blade 21 automatically resets under the drive of the elastic resetting member 3, simplifying the structure on the fan blade disc 1, reducing the difficulty of arranging a limiting structure between the fan blade 21 and the fan blade disc 1, and reducing the manufacturing cost of the ceiling fan light.

[0052] Referring to Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown in, in some embodiments, the limiting notch 23 extends circumferentially along the mounting post 22, and the limiting notch has a first abutting surface 231 and a second abutting surface 232 that are opposite to each other along the circumferential direction of the mounting post 22. When the fan blade 21 is folded, the limiting protrusion 11 abuts against the first abutting surface 231. When the fan blade 21 is unfolded, the limiting protrusion 11 abuts against the second abutting surface 232. With such a setting, the first abutting surface 231 and the second abutting surface 232 jointly define the range of movement of the limiting protrusion 11 relative to the mounting post 22, thereby limiting the rotation angle of the mounting post 22 relative to the fan blade disc 1, and the first abutting surface 231 and the second abutting surface 232 can determine the positions of the fan blade 21 when it is folded and unfolded, improving the accuracy of the positions of the fan blade 21 when it is unfolded and folded on the fan blade disc 1.

[0053] Specifically, the limiting notch 23 can be selected as an arc-shaped groove arranged on the mounting post 22. The first abutting surface 231 and the second abutting surface 232 are the inner walls at opposite ends of the arc-shaped groove. The position when the fan blade 21 is folded is the folding position, and the position when the fan blade 21 is unfolded is the unfolding position. The first abutting surface 231 is arranged on one side of the second abutting surface 232 in the direction from the folding position to the unfolding position.

[0054] Specifically, when the fan function needs to be turned off, the driving member 5 stops driving, the fan blade disc 1 gradually decelerates until it stops rotating, the centrifugal force slowly decreases until it disappears, and the fan blade 21 is subjected to an elastic force applied by the elastic reset member 3 in the direction towards the center of the fan blade disc 1, so that the fan blade 21 overcomes the centrifugal force and rotates towards the center of the fan blade disc 1 until the limiting protrusion 11 abuts against the first abutting surface 231, preventing the fan blade 21 from continuing to rotate towards the fan blade disc 1, maintaining the relative position stability between the fan blade 21 and the fan blade disc 1, and keeping the fan blade 21 in a closed state.

[0055] When the fan function needs to be used, the driving member 5 drives the fan blade disc 1 to rotate. The rotating fan blade disc 1 applies a centrifugal force in the direction away from the center of the fan blade disc 1 to the fan blade 21, causing the fan blade 21 to rotate and unfold relative to the fan blade disc 1 until the limiting protrusion 11 abuts against the second abutting surface 232, preventing the fan blade 21 from continuing to rotate in the direction away from the center of the fan blade disc 1, maintaining the relative position stability between the fan blade 21 and the fan blade disc 1, and keeping the fan blade 21 in an unfolded state.

[0056] When the driving member 5 drives the fan blade disc 1 to start rotating from a stationary state, the fan blade 21 rotates and unfolds in the direction away from the center of the fan blade disc 1; when the driving member 5 stops and the rotational speed of the fan blade disc 1 gradually decreases until it stops rotating, the fan blade 21 is subjected to an elastic force applied by the elastic reset member 3 in the direction towards the center of the fan blade disc 1, causing the fan blade 21 to rotate in the opposite direction relative to the fan blade disc 1 and reset. At this time, the limiting protrusion 11 on the fan blade 21 abuts against the first abutting surface 231, and the fan blade 21 remains in a closed state.

[0057] Refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 As shown in

[0058] In some embodiments, a receiving groove 24 is formed by recessing one surface of the mounting post 22 facing the fan blade disc 1, and a limiting notch 23 is formed on one side of the groove wall of the receiving groove 24 facing the fan blade disc 1; the elastic reset member 3 is a reset torsion spring, and the reset torsion spring is located in the receiving groove 24, and one end of the reset torsion spring is connected to the inner wall of the receiving groove 24. With such a setting, the reset torsion spring can provide an elastic force to drive the mounting post 22 to rotate. The reset torsion spring occupies a small space, can save the space required for installing the elastic reset member 3 on the fan blade disc 1, and the reset torsion spring can be protected by the receiving groove 24 in the receiving groove 24.

[0059] When the above-mentioned mounting post 22 is rotatably connected to the fan blade disc 1 by bolts, the surface of the groove wall of the accommodating groove 24 facing the fan blade disc 1 can be spaced from the fan blade disc 1, or it can also be in contact with the fan blade disc 1. The return torsion spring is arranged in the accommodating groove 24, and the return torsion spring is sleeved outside the bolt. The two ends of the return torsion spring are respectively connected to the fan blade disc 1 and the inner wall of the accommodating groove 24, so that the elastic force of the return torsion spring can drive the mounting post 22 to rotate relative to the fan blade disc 1.

[0060] Referring to Figure 1 、 Figure 7 and Figure 8 As shown in, in some embodiments, two adjacent and spaced limiting ribs are provided on the inner side surface of the groove wall of the accommodating groove 24, and a connecting groove 241 is formed between the two limiting ribs. One end of the return torsion spring is inserted and connected to the connecting groove 241. With such a setting, when one end of the return torsion spring is inserted into the connecting groove 241, the mounting post 22 can drive the return torsion spring to deform when rotating relative to the fan blade disc 1, which is convenient for the connection between the return torsion spring and the groove wall of the accommodating groove 24.

[0061] Specifically, the side surface of the groove wall of the accommodating groove 24 facing the internal space of the accommodating groove 24 can be selected as the inner side surface. The inner side surface of the groove wall of the accommodating groove 24 can be recessed towards the direction away from the internal space of the accommodating groove 24 to form a groove. In the direction around the center of the bottom of the accommodating groove 24, the opposite inner walls of the groove are the two limiting ribs; of course, two plate structures can also be provided on the groove wall of the accommodating groove 24 as the limiting ribs, and the two limiting ribs are spaced along the circumferential direction of the mounting post 22, and the space between the two limiting ribs is the connecting groove 241; the end of the return torsion spring is inserted into the connecting groove 241, so that when the mounting post 22 rotates relative to the fan blade disc 1, the return torsion spring can be driven to deform through the connecting groove 241.

[0062] Referring to Figures 1 to 4 As shown in, in some embodiments, an installation gap is formed between the side of the mounting post 22 facing the fan blade disc 1 and the fan blade disc 1; the return torsion spring includes a torsion spring body arranged in a spiral shape and two torsion feet connected to the two ends of the torsion spring body. The height of the torsion spring body in the axial direction of the fan blade disc 1 is greater than the height of the limiting protrusion 11 in the axial direction of the fan blade disc 1. The two side parts of the torsion spring body along the axial direction of the fan blade disc 1 are respectively in contact with the fan blade disc 1 and the bottom of the accommodating groove 24, and the two torsion feet are respectively connected to the mounting post 22 and the fan blade disc 1.

[0063] With such a setting, the installation gap can prevent the mounting post 22 from rubbing against the fan blade disc 1 when rotating and generating noise. The torsion feet protrude from the torsion spring cylinder, which is convenient for the connection between the torsion feet and the groove wall of the accommodating groove 24 and the fan blade disc 1. The contact between the torsion spring body and the bottom of the accommodating groove 24 and the fan blade disc 1 can limit the position of the torsion spring body in the accommodating groove 24 and improve the position stability of the return torsion spring in the accommodating groove 24.

[0064] Specifically, the mounting post 22 is rotatably connected to the fan blade disc 1 by bolts or a cylinder provided on the fan blade disc 1, so that a mounting gap can be formed by spacing between the mounting post 22 and the fan blade disc 1; the torsion spring body is a cylindrical structure, and the two torsion feet are respectively located at both ends of the cylindrical structure, so that the torsion foot close to the bottom of the receiving groove 24 is connected to the groove wall of the receiving groove 24, and the torsion foot close to the fan blade disc 1 is connected to the fan blade disc 1; the cylindrical torsion spring body is axially arranged in the receiving groove 24 along the fan blade disc 1, and the height of the torsion spring body is greater than the height of the limiting protrusion 11 in the axial direction of the fan blade disc 1, so that after the torsion spring body abuts against the bottom of the receiving groove 24 and the fan blade disc 1 in the receiving groove 24, the position stability of the return torsion spring in the receiving groove 24 can be improved.

[0065] Refer to Figure 1 、 Figure 3 and Figure 5 As shown in

[0068] Refer to Figure 1 、 Figure 3 and Figure 5 As shown in In some embodiments, the mounting protrusion 12 is provided with a mounting hole 13 for the fastener 4 to pass through, and the fastener 4 is rotatably connected to the mounting hole 13 and rotatably connected to the mounting post 22. With such a setting, the rotational connection between the fastener 4 and the mounting hole 13 and the connection with the mounting post 22 are simple and convenient, facilitating the rotational connection operation between the mounting post 22 and the fan blade disc 1, and the cost of the fastener 4 is low, which can reduce the cost of the fan light.

[0069] Specifically, the mounting hole 13 can be selected as a through hole, and the fastener 4 can be selected as a bolt or a screw. The bolt or screw is inserted into the mounting hole 13 to rotatably connect the fastener 4 with the mounting hole 13. The mounting post 22 is connected to the fastener 4 exposed in the mounting hole 13, so that when the fastener 4 rotates in the mounting hole 13, the mounting post 22 can rotate relative to the fan blade disc 1, realizing the rotational connection between the mounting post 22 and the fan blade disc 1 through the fastener 4. Of course, it is also possible to select a bearing provided in the mounting hole 13, a threaded hole provided on the mounting post 22, and the fastener 4 is a screw rod. One end of the screw rod is inserted into the mounting hole 13 and connected to the bearing in the mounting hole 13, and the other end is exposed outside the mounting hole 13 to be threadedly connected to the threaded hole of the mounting post 22, realizing the connection between the mounting post 22 and the fan blade disc 1 through the fastener 4.

[0070] Refer to Figure 1 、 Figure 3 and Figure 5 As shown in

[0071] Specifically, it can be selected that a through hole is provided as the connection hole on the side surface of the limiting protrusion 11 facing the mounting protrusion 12. One end of the elastic resetting member 3 is inserted into the connection hole, and the end of the elastic resetting member 3 in the connection hole keeps its position with the limiting protrusion 11, so that when the mounting post 22 rotates, the elastic resetting member 3 can elastically deform and apply an elastic force to the mounting post 22.

[0072] Refer to Figures 1 to 6 As shown in

[0073] With such a setting, multiple limiting protrusions 11 are respectively limited in multiple limiting notches 23, so that the rotation angles of multiple fan blades 21 are all limited. Multiple elastic resetting members 3 can respectively apply elastic forces to multiple mounting posts 22. When the fan blade disc 1 is stationary, multiple fan blades 21 are closed under the drive of the elastic resetting members 3. When the fan blade disc 1 rotates, the centrifugal force generated by the rotation of the fan blade disc 1 causes multiple fan blades 21 to overcome the elastic forces of the corresponding elastic resetting members 3 and unfold. Thus, the unfolded multiple fan blades 21 drive the air to flow simultaneously to realize the fan function of the fan lamp. The multiple fan blades 21 improve the efficiency of the fan lamp when blowing air, and the multiple fan blades 21 can rotate independently of each other, which is convenient for cleaning and replacing a single fan blade 21 on the fan blade disc 1.

[0074] Specifically, the number of the fan blades 21 and the elastic resetting members 3 can be selected as three. The three fan blades 21 are arranged at intervals along the circumferential direction of the fan blade disc 1. Three limiting protrusions 11 are provided on the fan blade disc 1. The three limiting protrusions 11 are respectively arranged corresponding to the three fan blades 21, so that an elastic resetting member 3 is connected between the mounting post 22 of each fan blade 21 and a corresponding limiting protrusion 11. The three limiting protrusions 11 are respectively inserted into the limiting notches 23 of the three mounting posts 22. Of course, the number of the fan blades 21, the elastic resetting members 3 and the limiting protrusions 11 can also be selected as other numbers, and the number of the fan blades 21, the elastic resetting members 3 and the limiting protrusions 11 is equal. A limiting protrusion 11 is provided at the corresponding position of each mounted fan blade 21 on the fan blade disc 1, so that the multiple limiting protrusions 11 are correspondingly inserted and connected with the limiting notches 23 on the multiple mounting posts 22. An elastic resetting member 3 is connected between the mounting post 22 of each fan blade 21 and a corresponding limiting protrusion 11, so that the multiple elastic resetting members 3 can respectively apply elastic forces to the multiple mounting posts 22, so as to drive the multiple fan blades 21 to close by the multiple elastic resetting members 3.

[0075] Referring to Figures 1 to 4 As shown, in some embodiments, the driving member 5 includes a motor, and the motor is connected to the center of the fan blade disc 1 to drive the fan blade disc 1 to rotate through the motor. With such a setting, the motor can control the rotation and stop of the fan blade disc 1. When the fan lamp needs to blow air, the motor drives the fan blade disc 1 to rotate, so that the fan blades 21 unfold, and the fan blades 21 drive the air to flow, which is convenient for the user to independently turn on and off the fan function of the fan lamp.

[0076] Specifically, a motor can be provided on one side of the fan blade disc 1 where the limiting protrusions 11 are provided, and the motor is installed at the center of the fan blade disc 1, so that the motor can drive the fan blade disc 1 to rotate around its own axis after starting. The motor can be connected to the fan blade disc 1 by bolts, and of course, it can also be connected to the fan blade disc 1 by riveting.

[0077] In the specific assembly of the ceiling fan lamp provided by the embodiment of the present utility model, during assembly, the mounting post 22 is rotatably connected to the mounting protrusion 12 on the fan blade disc 1 through the fastener 4, the limiting protrusion 11 is inserted into the limiting notch 23, one end of the elastic reset member 3 is connected to the limiting protrusion 11, and the other end is connected to the mounting post 22. The elastic force of the elastic reset member 3 drives the fan blades 21 to close; when the fan blade disc 1 is stationary, the elastic reset member 3 causes the fan blades 21 to rotate towards the center of the fan blade disc 1, and the limiting protrusion 11 abuts against the first abutting surface 231, so that the fan blades 21 are kept in the closed position, so as to close the fan blades 21; when it is necessary to expand the fan blades 21, the driving member 5 is used to drive the fan blade disc 1 to rotate. The centrifugal force generated by the rotation of the fan blade disc 1 overcomes the elastic force of the elastic reset member 3, causing the fan blades 21 to rotate away from the center of the fan blade disc 1, so that the fan blades 21 rotate to the expanded position, and the limiting protrusion 11 abuts against the second abutting surface 232, so that the fan blades 21 are kept in the expanded position, so as to expand the fan blades 21 on the fan blade disc 1; when it is necessary to close the fan blades 21, the driving member 5 stops working, causing the fan blade disc 1 to gradually stop rotating, and the elastic reset member 3 drives the fan blades 21 to rotate towards the center of the fan blade disc 1 to complete the reset, so that the fan blades 21 rotate to the closed position, so as to close the fan blades 21.
