DETAILED DESCRIPTION

[0036] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0038] Reference Figures 1 to 8 As shown, an embodiment of the utility model provides a fan lamp, comprising: a fan blade disc 1, a driving member 6 and a plurality of fan blade assemblies.

[0039] Among them, the fan disk 1 has a first side surface and a second side surface that are relatively arranged; a plurality of fan blade assemblies are arranged on the fan disk 1 at intervals along the circumference of the fan disk 1, and the plurality of fan blade assemblies are arranged independently of each other and are respectively connected to the fan disk 1; the driving member is connected to the fan disk 1 and is configured to drive the fan disk 1 to rotate.

[0040] Specifically, each fan blade assembly includes a fan blade 2, a mounting seat 3 and an elastic reset member 4; the fan blade 2 is arranged on the first side surface of the fan blade disk 1 and is rotatably connected to the fan blade disk 1, and is configured to unfold relative to the fan blade disk 1 under the drive of the fan blade disk 1; the mounting seat 3 is arranged on the second side surface of the fan blade disk 1, and is correspondingly arranged and fixedly connected to the fan blade 2; the elastic reset member 4 is connected between the mounting seat 3 and the fan blade disk 1, and is configured to drive the corresponding mounting seat 3 and the fan blade 2 to rotate and reset relative to the fan blade disk 1, so that the fan blade 2 is closed relative to the fan blade disk 1.

[0041] In other words, a fan lamp provided by an embodiment of the utility model includes: a fan disk 1, having a first side surface and a second side surface arranged opposite to each other; a plurality of blades 2, arranged on the first side surface of the fan disk 1 at intervals along the circumference of the fan disk 1, and respectively connected to the fan disk 1 for rotation; a driving member 6, connected to the fan disk 1, configured to drive the fan disk 1 to rotate, and drive the blades 2 to unfold relative to the fan disk 1, and the plurality of blades 2 are independently arranged; a plurality of mounting seats 3, arranged on the second side surface of the fan disk 1 at intervals along the circumference of the fan disk 1, and corresponding to and fixed to the plurality of blades 2 one by one, and the plurality of mounting seats 3 are independently arranged; wherein, an elastic reset member 4 is connected between each mounting seat 3 and the fan disk 1, and the elastic reset member 4 is configured to drive the corresponding mounting seat 3 to rotate and reset relative to the fan disk 1, so as to drive the blades 2 to rotate and reset relative to the fan disk 1, so as to close the blades 2.

[0042] When the fan function is needed, the driving member 6 drives the fan disc 1 to rotate. The fan disc 1 will generate centrifugal force during the rotation, and the fan blades 2 will rotate relative to the fan disc 1 under the action of the centrifugal force. Specifically, the fan blades 2 can be thrown out in a direction away from the center of the fan disc 1 under the action of the centrifugal force to unfold the fan blades 2; after the fan blades 2 are unfolded relative to the fan disc 1, during the continuous rotation of the fan disc 1, the fan blades 2 will remain in the unfolded state due to the action of the centrifugal force, and rotate synchronously with the fan disc 1; and, during the process of the driving member 6 driving the fan disc 1 to rotate, the fan blades 2 are rotated and unfolded relative to the fan disc 1 due to the action of the centrifugal force, causing the elastic reset member 4 connected between the mounting seat 3 and the fan disc 1 to deform and store elastic potential energy.

[0043] When the fan function is not needed, the driving member 6 stops driving, that is, after the driving member 6 stops providing the rotation function to the fan disc 1, the fan disc 1 will gradually slow down and stop rotating, and the centrifugal force generated by the rotation of the fan disc 1 will slowly decrease and disappear, and the elastic reset member 4 releases the elastic potential energy and restores the state before deformation, so that the fan blades 2 rotate in the opposite direction and reset relative to the fan disc 1 under the elastic force of the elastic reset member 4, so that the fan blades 2 rotate relative to the fan disc 1 to a closed state.

[0044] Specifically, the fan blade disk 1 is a circular disk, and the surfaces on both sides of the axial direction of the fan blade disk 1 are divided into a first side surface and a second side surface; the fan blade disk 1 can be optionally provided with a through hole, and the through hole penetrates the fan blade disk 1 along the axial direction, so that the fan blade 2 is arranged on the first side surface and is fixedly connected with the mounting seat 3 on the second side surface through the through hole, so that when the fan blade 2 rotates, the mounting seat 3 rotates with the fan blade 2; of course, the fan blade 2 can also be selected to be rotatably connected to the first side surface of the fan blade disk 1, and a bracket is connected to the fan blade 2, and the bracket extends from the outer side of the edge of the fan blade disk 1 to the second side surface, and the mounting seat 3 is rotatably connected to the second side surface, and the bracket is connected to the edge of the mounting seat 3, so that the rotation of the fan blade 2 drives the mounting seat 3 to rotate.

[0045] The driving member 6 can be a motor or a rotating cylinder or other mechanism. The driving member 6 can be connected to the center of the impeller disk 1 so that the driving member 6 can drive the impeller disk 1 to rotate around its own central axis after being started.

[0046] A through hole can be optionally set at one end of the above-mentioned fan blade 2, and a through hole is set on the fan blade disk 1, one end of the bolt is fixedly connected to the fan blade 2, and the other end is rotatably connected to the through hole of the fan blade disk 1, so that the fan blade 2 is rotatably connected to the fan blade disk 1. Of course, it is also possible to choose to set a column along the axial direction of the fan blade disk 1 on the fan blade disk 1, set a through hole on the fan blade 2, and the column on the fan blade disk 1 is rotatably connected to the through hole on the fan blade 2, so that the fan blade 2 is rotatably connected to the fan blade disk 1.

[0047] The elastic reset member 4 can be selected as a long strip-shaped tension spring, which is arranged along the circumference of the blade disk 1, one end of the tension spring is connected to the second side surface, and the other end is connected to the mounting seat 3, and the tension spring applies an elastic force to the blade 2 to drive the blade 2 to rotate toward the center of the blade disk 1 during the process of the blade 2 being expanded and closed. Of course, the mounting seat 3 and the blade disk 1 can also be fixedly connected by bolts, and the mounting seat 3 and the blade disk 1 are spaced apart, and the elastic reset member 4 is a torsion spring, which is arranged between the mounting seat 3 and the blade disk 1, and the torsion spring is sleeved on the outside of the bolt, and the two ends of the torsion spring are respectively connected to the mounting seat 3 and the second side surface of the blade disk 1, so that when the blade 2 rotates relative to the blade disk 1, the torsion spring deforms and can drive the blade 2 to rotate toward the center of the blade disk 1.

[0048] When the above-mentioned fan disc 1 is stationary, the elastic reset part 4 causes the fan blades 2 to rotate toward the center of the fan disc 1, and the axial projection of the fan blades 2 on the fan disc 1 is completely located inside the fan disc 1. The fan blades 2 are closed on the fan disc 1. At this time, the position of the fan blades 2 is the closed position; when the fan disc 1 rotates, the centrifugal force of the rotation of the fan disc 1 causes the fan blades 2 to rotate in the direction away from the center of the fan disc 1, causing the fan blades 2 to rotate from the closed position to a position extending out of the fan disc 1 in the radial direction of the fan disc 1. At this time, the fan blades 2 are in the expanded position and the fan blades 2 are in the expanded state.

[0049] When the fan blades 2 are in the expanded position, the elastic return member 4 is in a deformed state and stores elastic potential energy. When the driving member 6 stops driving, that is, after the driving member 6 stops providing the rotation function to the fan blade disk 1, the fan blade disk 1 will gradually slow down to stop rotating, and the elastic return member 4 releases the elastic potential energy and restores the state before deformation, so that the elastic return member 4 drives the fan blades 2 back to the closed position to complete the reset, so that the fan blades 2 rotate to the closed state relative to the fan blade disk 1; in the process of the rotation speed of the fan blade disk 1 gradually decreasing until it stops, the elastic return member 4 causes the fan blades 2 to gradually rotate toward the closed position and rotate to the closed position.

[0050] When the fan lamp provided by the embodiment of the utility model is used, the fan blades 2 are rotatably connected to the fan blade disk 1, the mounting seat 3 is arranged on the second side surface and fixedly connected to the fan blades 2, one end of the elastic reset member 4 is connected to the second side surface of the fan blade disk 1, and the other end is connected to the mounting seat 3; the elastic force of the multiple elastic reset members 4 drives the multiple fan blades 2 to close, and when the fan blade disk 1 is stationary, the elastic reset member 4 causes the fan blades 2 to rotate toward the center of the fan blade disk 1, so that the multiple fan blades 2 are closed; when the fan blades 2 need to be unfolded, the fan blade disk 1 is driven to rotate by the driving member 6, and the centrifugal force generated by the rotation of the fan blade disk 1 overcomes the elastic force of the elastic reset member 4 and causes the fan blades 2 to rotate in a direction away from the center of the fan blade disk 1, so that the fan blades 2 are unfolded on the fan blade disk 1; when the fan blades 2 need to be closed, the driving member 6 stops working and the fan blade disk 1 gradually stops from rotating, and the elastic reset member 4 drives the fan blades 2 to rotate toward the center of the fan blade disk 1, so that the fan blades 2 gradually rotate toward the closed position, and return to the closed position to complete the reset, so that the fan blades 2 are closed.

[0051] The fan lamp provided by the embodiment of the utility model is provided with a fan blade assembly including a fan blade 2, a mounting seat 3 and an elastic reset member 4. The fan blade 2 is rotatably arranged on the first side surface of the fan blade disk 1, the mounting seat 3 is arranged on the second side surface and fixedly connected to the fan blade 2, and the elastic reset member 4 is connected between the mounting seat 3 and the fan blade disk 1. When the fan blade needs to be unfolded, the driving member 6 is used to drive the fan blade disk 1 to rotate and drive the fan blade to unfold relative to the fan blade disk to unfold the fan blade. When the fan blade 2 needs to be closed, the elastic reset member 4 is used to drive the mounting seat 3 to rotate. The mounting seat 3 rotates and drives the fan blade 2 to rotate and reset relative to the fan blade disk 1 to close the fan blade 2, thereby ensuring the realization of the opening and closing function of the fan blade assembly, and multiple fan blade assemblies are respectively installed on the fan blade disk 1 and are arranged at intervals along the circumference of the fan blade disk 1, and the multiple fan blade assemblies are independent of each other. With such an arrangement, multiple fan blade assemblies can be independently unfolded and closed, which facilitates the individual disassembly and installation of the fan blade assemblies for inspection and replacement, simplifies the inspection and replacement of the fan blade assemblies on the fan blade disk 1, and improves the convenience of repairing and replacing the fan blade assemblies on the fan lamp.

[0052] Reference Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a limit block 23 is provided on the fan blade 2 or the mounting seat 3, and a limit assembly corresponding to the limit block 23 is provided on the fan disc 1, and the limit assembly includes a first baffle 131 and a second baffle 132 arranged at intervals, and the limit block 23 is limited between the first baffle 131 and the second baffle 132; when the fan blade 2 is unfolded, the limit block 23 abuts against the first baffle 131, and when the fan blade 2 is closed, the limit block 23 abuts against the second baffle 132 to limit the rotation angle of the fan blade 2 relative to the fan disc 1. In this way, the first baffle 131 and the second baffle 132 jointly limit the movement range of the limit block 23, so that the cooperation between the limit block 23 and the limit assembly is realized to limit the rotation angle of the fan blade 2 relative to the fan disc 1, and the first baffle 131 and the second baffle 132 can determine the position of the fan blade 2 when it is closed and unfolded, and improve the accuracy of the position of the fan blade 2 when it rotates on the fan disc 1.

[0053] Specifically, the limit block 23 can be selectively set on the side of the fan blade 2 facing the fan blade disk 1, the limit block 23 protrudes from the surface of the fan blade 2, and a limit assembly is set on the first side surface of the fan blade disk 1, so that the limit block 23 is located between the first baffle 131 and the second baffle 132 of the limit assembly to limit the movement range of the limit block 23, thereby achieving the limitation of the rotation angle of the fan blade 2 relative to the fan blade disk 1; of course, the limit block 23 can also be selected to be set on the edge of the mounting seat 3, and the limit assembly is set on the second side surface of the fan blade disk 1, the limit block 23 is located between the first baffle 131 and the second baffle 132 of the limit assembly, limiting the movement range of the limit block 23, so that the rotation angle of the mounting seat 3 is limited, and the mounting seat 3 is fixedly connected to the fan blade 2 and rotates together, thereby achieving the effect of limiting the rotation of the fan blade 2 relative to the fan blade disk 1.

[0054] The above-mentioned first baffle 131 and second baffle 132 can be selectively arranged around the rotational connection point between the fan blade 2 and the fan blade disk 1, and the position when the fan blade 2 is closed can be selected as the closed position, and the position when the fan blade 2 is unfolded can be selected as the unfolded position. In the direction from the closed position to the unfolded position, the first baffle 131 is arranged on one side of the second baffle 132 in the direction from the closed position to the unfolded position.

[0055] Specifically, when the fan function needs to be turned off, the driving member 6 stops driving, the fan disc 1 gradually slows down to stop rotating, the centrifugal force slowly decreases to disappear, and the elastic force of the elastic reset member 4 overcomes the centrifugal force to reset the fan blades 2. The fan blades 2 are subjected to the elastic force applied by the elastic reset member 4 in the direction close to the center of the fan disc 1, so that the fan blades 2 overcome the centrifugal force and rotate in the direction close to the center of the fan disc 1 until the limit block 23 abuts against the first baffle 131, so that the fan blades 2 cannot continue to rotate in the direction close to the fan disc 1, and the relative position between the fan blades 2 and the fan disc 1 remains stable, and the fan blades 2 remain in a closed state.

[0056] When the fan function is needed, the driving member 6 drives the fan disc 1 to rotate, and the rotating fan disc 1 applies a centrifugal force to the fan blades 2 in the direction away from the center of the fan disc 1, so that the fan blades 2 rotate and unfold relative to the fan disc 1 until the limit block 23 on the fan blades 2 abuts against the second baffle 132, so that the fan blades 2 cannot continue to rotate in the direction away from the center of the fan disc 1, and the relative position between the fan blades 2 and the fan disc 1 remains stable, and the fan blades 2 remain in the unfolded state.

[0057] When the driving member 6 drives the fan disk 1 to rotate from a stationary state, the fan blades 2 rotate in the direction away from the center of the fan disk 1 and unfold; when the driving member 6 stops and the rotation speed of the fan disk 1 gradually decreases until it stops rotating, the fan blades 2 are subjected to the elastic force applied by the elastic reset member 4 in the direction close to the center of the fan disk 1, causing the fan blades 2 to rotate in the opposite direction relative to the fan disk 1 and reset. At this time, the limit block 23 on the fan blade 2 abuts against the first baffle 131, and the fan blade 2 remains in a closed state.

[0058] Reference Figures 3 to 5 As shown, in some embodiments, the limit block 23 is arranged on the fan blade 2, and the limit assembly is arranged on the first side surface of the fan blade disk 1; or, the limit block 23 is arranged on the mounting seat 3, and the limit assembly is arranged on the second side surface of the fan blade disk 1. In this way, the limit block 23 is arranged on the fan blade 2 or the mounting seat 3, and the limit assembly is correspondingly arranged on the first side surface and the second side surface, so that the limit block 23 and the limit assembly can cooperate with each other.

[0059] Specifically, a limit block 23 can be optionally provided on the side surface of the fan blade 2 facing the fan blade disk 1. Of course, the fan blade 2 can also include a fan blade body 21 and a mounting column 22 connected to one end of the fan blade body 21, and the mounting column 22 is rotatably connected to the fan blade disk 1. The limit block 23 is arranged on the side of the mounting column 22, and the first baffle 131 and the second baffle 132 are arranged around the mounting column 22.

[0060] Of course, the above-mentioned limit block 23 can also be protruded from the edge of the mounting seat 3, and the first blocking piece 131 and the second blocking piece 132 are arranged around the mounting seat 3, so that the limit block 23 can be located between the first blocking piece 131 and the second blocking piece 132.

[0061] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, in some embodiments, the fan blade 2 includes a fan blade body 21 and a mounting post 22 connected to one end of the fan blade body 21; the fan blade disc 1 is provided with a plurality of rotating holes 11 corresponding to the plurality of mounting posts 22, and a fastener 5 is passed through the rotating hole 11, and the fastener 5 is rotatably connected to the rotating hole 11, and one end of the fastener 5 is connected to the mounting post 22, and the other end is connected to the mounting seat 3. In this way, the mounting post 22 is used as a structure rotatably connected to the fan blade disc 1, which facilitates the connection between the fan blade body 21 and the fan blade disc 1.

[0062] Specifically, a mounting post 22 can be selected to be set at one end of the blade body 21, and the mounting post 22 extends in a direction perpendicular to the extension direction of the blade body 21 toward a direction away from the blade body 21. A screw hole can be selected to be set on the side surface of the mounting post 22 facing the blade disk 1, and a through hole is set on the blade disk 1 as a rotating hole 11, and the rotating hole 11 passes through the blade disk 1 along the axial direction of the blade disk 1; a bolt or a screw can be selected as the fastener 5, and the bolt or screw is inserted into the rotating hole 11 on the blade disk 1, and the bolt or screw is spaced from the inner wall of the rotating hole 11, one end of the bolt or screw is threadedly connected to the screw hole on the mounting post 22, and the other end is fixedly connected to the mounting seat 3; of course, a bearing can also be selected to be set in the rotating hole 11, and the fastener 5 is connected to the inner side of the bearing, so that the bolt is rotatably set in the rotating hole 11 through the bearing.

[0063] The above-mentioned limit block 23 can be selectively set on the outer surface of the mounting column 22, and of course, it can also be selected to be set on the outer surface of the mounting seat 3, as long as the limit block 23 can cooperate with the limit assembly to achieve the effect of limiting the rotation of the fan blade 2 relative to the fan blade disk 1.

[0064] Reference Figure 1 and Figure 3 As shown, in some embodiments, a ball 24 is provided on the side of the mounting post 22 facing the blade disk 1, and the ball 24 is in contact with the blade disk 1. With such a configuration, when the mounting post 22 rotates relative to the blade disk 1, the ball 24 rolls in the groove, reducing the friction between the mounting post 22 and the blade disk 1 when the mounting post 22 rotates.

[0065] Specifically, the side of the installation column 22 facing the fan disk 1 can be selected to be concave to form a groove, and the ball 24 is arranged in the groove. The ball 24 and the inner wall of the groove are spaced apart so that the ball 24 can roll in the groove, and part of the ball 24 is exposed at the notch of the groove, so that the ball 24 exposed on the outside of the groove abuts against the fan disk 1. When the installation column 22 rotates relative to the fan disk 1, the ball 24 rolls in the groove.

In this way, the mounting annular grooves 12 are arranged around the connection point between the mounting column 22 and the blade disk 1, so that the ball 24 can always remain in the mounting annular grooves 12 when the mounting column 22 rotates, so that the mounting annular grooves 12 limit the rolling trajectory of the ball 24, and improve the stability of the ball 24 when the mounting column 22 rotates.

[0067] Specifically, a ring-shaped groove is recessed on the first side surface of the impeller disk 1 as the mounting ring groove 12, and the connection point between the impeller disk 1 and the mounting column 22 is located on the inner side of the mounting ring groove 12, so that after the mounting column 22 is connected to the impeller disk 1, the ball 24 on the mounting column 22 can be arranged relative to the mounting ring groove 12 in the axial direction of the impeller disk 1, so that the ball 24 can be inserted into the mounting ring groove 12, and the rotation of the mounting column 22 can drive the ball 24 to roll in the mounting ring groove 12.

[0068] Reference Figure 1 , Figure 3 and Figure 7 As shown, in some embodiments, there are multiple balls 24, and the multiple balls 24 are arranged at intervals around the fastener 5, and the multiple balls 24 are all in contact with the fan blade disk 1. In this way, when the mounting column 22 rotates, the multiple balls 24 roll on the mounting column 22 to reduce the friction of the mounting column 22, and the multiple balls 24 are arranged at intervals on the mounting column 22. When the multiple balls 24 are in contact with the fan blade disk 1, the position of the mounting column 22 can be balanced, so that a stable angle is maintained between the mounting column 22 and the fan blade disk.

[0069] Specifically, the number of balls 24 can be selected to be four, and the four balls 24 are arranged at intervals. The four balls 24 are all in contact with the fan blade disk 1, so that when the mounting column 22 rotates, the four balls 24 roll on the mounting column 22. Of course, other numbers of balls 24 can also be selected. As long as multiple balls 24 roll on the mounting column 22 when the mounting column 22 rotates, the effect of reducing the friction when the mounting column 22 rotates can be achieved.

[0070] Reference Figure 1 , Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments, the elastic reset member 4 includes a torsion spring, which is sleeved on the outside of the fastener 5 and connected between the mounting seat 3 and the fan blade disc 1. In this way, the torsion spring has a simple structure and occupies less space in the direction parallel to the fan blade disc 1, which can improve the space utilization of the second side surface of the fan blade disc 1, and the mounting post 22 rotates around the fastener 5 when the mounting post 22 rotates. The torsion spring is sleeved on the outside of the fastener 5, which facilitates the deformation of the torsion spring with the rotation of the mounting post 22 to apply elastic force to the mounting post 22 through the mounting seat 3.

[0071] Specifically, the torsion spring is a cylindrical spring formed by bending and coiling. The torsion spring is arranged along the axial direction of the fan blade disk 1, and the torsion spring is sleeved on the outside of the fastener 5. The two ends of the torsion spring are respectively connected to the second side surface and the mounting seat 3, so that during the expansion and closing process of the fan blades 2, the torsion spring is in a deformed state and exerts an elastic force on the fan blades 2 to drive the fan blades 2 to rotate toward the center of the fan blade disk 1.

[0072] Reference Figure 1 , Figure 3 , Figure 6 and Figure 8 As shown, in some embodiments, the mounting seat 3 is recessed on one side facing the blade disc 1 to form a mounting groove 31, a connecting groove 311 is formed on the groove wall of the mounting groove 31, a torsion spring is arranged in the mounting groove 31, one end of the torsion spring is plug-connected with the connecting groove 311, and the other end is connected with the blade disc 1. In this way, when one end of the torsion spring is inserted into the connecting groove 311, the torsion spring can be deformed by the rotation of the mounting seat 3 when the mounting column 22 rotates relative to the blade disc 1, so that the torsion spring can be conveniently installed between the mounting seat 3 and the blade disc 1.

[0073] Specifically, the mounting post 22 is recessed on one side facing the fan blade disc 1 to form a mounting groove 31 with a circular groove bottom, the groove wall of the mounting groove 31 is an annular plate body, and the torsion spring is arranged inside the mounting groove 31. The groove wall of the mounting groove 31 can be selected to face the inner space of the mounting groove 31 as the inner side surface, and the inner side surface of the groove wall of the mounting groove 31 can be selected to be recessed in a direction away from the inner space of the mounting groove 31 to form a groove as the connecting groove 311. Of course, two plate structures can also be selected to be arranged on the groove wall of the mounting groove 31, and the two plate structures are arranged at intervals along the circumference of the mounting post 22, and the space between the two plate structures forms the mounting groove 31.

[0074] One end of the torsion spring can be selected to be inserted into the connecting groove 311, and the other end is connected to the second side surface. The torsion spring can be selected to be connected to the second side surface by a bolt. Of course, a through hole can also be selected to be set on the second side surface, and one end of the torsion spring is plugged into the through hole. Therefore, when the mounting base 3 rotates, the end of the torsion spring plugged into the connecting groove 311 of the mounting base 3 rotates relative to the end of the torsion spring connected to the second side surface, so that the torsion spring is elastically deformed and applies elastic force to the mounting base 3.

[0075] Reference Figure 1 , Figure 3 , Figure 6 and Figure 8As shown, in some embodiments, the driving member 6 includes a motor, which is connected to the center of the fan disc 1 to drive the fan disc 1 to rotate. In this way, the motor can control the rotation and stop of the fan disc 1. When the fan lamp needs to blow air, the motor drives the fan disc 1 to rotate to unfold the fan blades 2, and the fan blades 2 drive the air flow, which is convenient for users to control the independent opening and closing of the fan function of the fan lamp.

[0076] Specifically, a motor can be provided on the first side surface of the fan disk 1, and the motor can be installed at the center of the fan disk 1, so that after the motor is started, it can drive the fan disk 1 to rotate around its own axis. The motor can be connected to the fan disk 1 using bolts, and of course, it can also be connected to the fan disk 1 by riveting.

[0077] When the fan lamp provided by the embodiment of the utility model is used, the mounting column 22 is rotatably connected to the rotating hole 11 on the fan blade disk 1 through the fastener 5, the part of the fastener 5 located on the second side surface is connected to the mounting seat 3, and the elastic reset member 4 is arranged in the mounting groove 31 of the mounting seat 3, one end of the elastic reset member 4 is plugged and connected to the connecting groove 311 on the groove wall of the mounting groove 31, and the other end is connected to the second side surface, so that the elastic force of the elastic reset member 4 drives the fan blades 2 to close.

[0078] When the fan disk 1 is stationary, the elastic reset member 4 causes the fan blades 2 to rotate toward the center of the fan disk 1, and the limit block 23 abuts against the first baffle 131, so that the fan blades 2 are kept in the closed position to close the fan blades 2; when the fan blades 2 need to be unfolded, the drive member 6 is used to drive the fan disk 1 to rotate, and the centrifugal force of the rotation of the fan disk 1 overcomes the elastic force of the elastic reset member 4 to cause the fan blades 2 to rotate in the direction away from the center of the fan disk 1, so that the limit block 23 abuts against the second baffle 132, thereby rotating the fan blades 2 to the unfolded position, so that the fan blades 2 are unfolded on the fan disk 1.

[0079] When the fan blades 2 need to be closed, the driving member 6 stops working and the fan disc 1 gradually stops rotating. The elastic reset member 4 drives the fan blades 2 to rotate toward the center of the fan disc 1 to complete the reset, so that the fan blades 2 return to the closed position, so that the fan blades 2 are closed.
