[0002] A fan light is a device that has both lighting and fan functions. For the sake of aesthetics and to reduce dust on the blades, the blades of the fan light are configured to rotate relative to the fan disk. When the fan function is needed, the blades rotate relative to the fan disk under the action of centrifugal force and extend out from the fan disk. When the fan function is not needed, the blades rotate in the opposite direction relative to the fan disk and are retracted on the fan disk under the action of an elastic reset member (such as a reset spring).

[0003] In order to ensure the realization of the fan blade opening and closing function, a mounting seat or a rotating seat or other structures are usually set between the fan blade and the fan blade disk, or a mounting seat or a rotating seat or other structures are set on the surface of the fan blade disk facing away from the fan blade, so as to provide an installation or connection point for the elastic reset member (such as a reset spring) and set a limit point for limiting the rotation angle of the fan blade. However, the setting of the mounting seat or the rotating seat increases the complexity of the fan blade installation structure and affects the assembly efficiency of the fan lamp.

DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] Reference Figures 1 to 7 As shown, an embodiment of the utility model provides a fan lamp, comprising: a fan blade disc 1, fan blades 2, a driving member 5 and a reset spring 3.

[0035] The impeller disk 1 has a first side surface and a second side surface that are arranged opposite to each other; the blades 2 are arranged on the first side surface of the impeller disk 1 and are rotationally connected to the impeller disk 1. The driving member 5 is connected to the impeller disk 1 and is configured to drive the impeller disk 1 to rotate and drive the blades 2 to unfold relative to the impeller disk 1 to unfold the blades 2. Specifically, the driving member 5 drives the impeller disk 1 to rotate, and the impeller disk 1 generates centrifugal force during the rotation process. The blades 2 rotate relative to the impeller disk 1 under the action of the centrifugal force. Specifically, the blades 2 can be thrown away from the center of the impeller disk 1 under the action of the centrifugal force to unfold the blades 2; after the blades 2 are unfolded relative to the impeller disk 1, during the continuous rotation of the impeller disk 1, the blades 2 are kept in the unfolded state under the action of the centrifugal force and rotate synchronously with the impeller disk 1.

[0036] Among them, the fan blade 2 is provided with a limiting portion 23 which protrudes and extends toward the second side surface of the fan blade disk 1, and the fan blade disk 1 is provided with a limiting groove 11 which passes through the first side surface and the second side surface of the fan blade disk 1. The limiting portion 23 is passed through the limiting groove 11 to limit the rotation angle of the fan blade 2 relative to the fan blade disk 1; the reset spring 3 is arranged on the second side surface of the fan blade disk 1, one end of the reset spring 3 is connected to the fan blade disk 1, and the other end is connected to the limiting portion 23, and is configured to drive the fan blade 2 to close relative to the fan blade disk 1 so as to close the fan blade 2.

[0037] Specifically, during the process of the driving member 5 driving the blade disc 1 to rotate, the blade 2 is subjected to the centrifugal force and rotates and unfolds relative to the blade disc 1, so that the reset spring 3 connected between the blade 2 and the blade disc 1 is deformed and stores 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 blade disc 1, the blade disc 1 will gradually slow down to stop rotating, and the centrifugal force generated by the rotation of the blade disc 1 will slowly decrease to disappear, and the reset spring 3 releases the elastic potential energy and restores the state before deformation, so that the blade 2 rotates in the opposite direction and resets relative to the blade disc 1 under the elastic force of the reset spring 3, thereby realizing the function of using the reset spring 3 to drive the blade 2 to reset, so that the blade 2 rotates relative to the blade disc 1 to the closed state. In this way, the blade 2 rotates relative to the blade disc 1 to realize the expansion or closing of the blade 2 relative to the blade disc 1, that is, the opening and closing function of the blade 2 is realized.

[0038] Specifically, the impeller disk 1 is a circular disk, and the surfaces on both sides of the impeller disk 1 in the axial direction are divided into a first side surface and a second side surface; the limiting groove 11 is a through groove that penetrates the impeller disk 1 along the axial direction of the impeller disk 1, so that the limiting portion 23 can extend from the first side surface through the limiting groove 11 to the second side surface. The driving member 5 can be selected as a mechanism such as a motor or a rotating cylinder, and the driving member 5 can be selected to be connected to the center of the impeller disk 1, so that the driving member 5 drives the impeller disk 1 to rotate around its own central axis after being started.

[0039] A through hole can be optionally set at one end of the above-mentioned fan blade 2, and a through hole can be 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.

[0040] The above-mentioned reset tension spring 3 can be selected as a long strip tension spring, which is arranged along the circumference of the fan blade disk 1, one end of the tension spring is connected to the second side surface, and the other end is connected to the limiting portion 23, and the tension spring applies an elastic force to the fan blade 2 to drive the fan blade 2 to rotate toward the center of the fan blade disk 1 during the process of expanding and closing the fan blade 2.

[0041] When the above-mentioned fan disc 1 is stationary, the reset spring 3 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, so that 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, thereby 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 expanded on the fan disc 1.

[0042] When the fan blades 2 are in the expanded position, the reset spring 3 is in a deformed state and stores elastic potential energy. When the driving member 5 stops driving, that is, when the driving member 5 stops providing the rotation function to the fan blade disk 1, the fan blade disk 1 will gradually slow down and stop rotating. The centrifugal force generated by the rotation of the fan blade disk 1 will slowly decrease until it disappears. The reset spring 3 overcomes the centrifugal force and releases the elastic potential energy, and restores the state before deformation, so that the reset spring 3 drives the fan blades 2 to gradually rotate toward the closed position and return to the closed position to complete the reset, thereby closing the fan blades 2.

[0043] When the fan lamp provided by the embodiment of the utility model is used, the fan blade 2 is rotatably connected to the fan blade disk 1, and the limiting portion 23 is inserted into the limiting groove 11, so that the limiting portion 23 is inserted into the limiting groove 11, and one end of the reset spring 3 is connected to the second side surface of the fan blade disk 1, and the other end is connected to the limiting portion 23; the elastic force of the reset spring 3 drives the fan blade 2 to close, and when the fan blade disk 1 is stationary, the reset spring 3 causes the fan blade 2 to rotate toward the center of the fan blade disk 1, so that the fan blade 2 is closed; when the fan blade 2 needs to be unfolded, The driving member 5 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 reset spring 3 to rotate the fan blades 2 in the direction away from the center of the fan disk 1, so that the fan blades 2 are unfolded on the fan disk 1; when the fan blades 2 need to be closed, the driving member 5 stops working and the fan disk 1 gradually stops rotating, and the reset spring 3 drives the fan blades 2 to rotate toward the center of the fan 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.

[0044] The fan lamp provided by the embodiment of the utility model is provided with a limiting portion 23 on the fan blade 2, and a limiting groove 11 passing through the fan blade disc 1 is provided on the fan blade disc 1. When the fan blade 2 is installed on the first side surface of the fan blade disc 1, the limiting portion 23 can pass through the limiting groove 11 to make a part of the limiting portion 23 appear on the second side surface; at the same time, the limiting portion 23 passes through the limiting groove 11 and is connected to the reset spring 3 on the second side surface of the fan blade disc 1. When it is necessary to unfold the fan blade 2, the driving member 5 is used to drive the fan blade disc 1 to rotate and drive the fan blade 2 to unfold relative to the fan blade disc 1 to unfold the fan blade 2. When it is necessary to close the fan blade 2, the reset spring 3 is used to drive the fan blade 2 to rotate relative to the fan blade disc 1 and reset to close the fan blade 2, thereby ensuring the realization of the opening and closing function of the fan blade 2. With such a configuration, the cooperation between the limiting portion 23 and the limiting groove 11 can limit the rotation angle of the fan blade 2 relative to the fan disc 1, and the connection between the limiting portion 23 and the reset spring 3 can enable the elastic force of the reset spring 3 to be applied to the fan blade 2 to drive the fan blade 2 to reset; there is no need to set a mounting seat or a rotating seat or other structures between the fan blade 2 and the fan disc 1, so that the fan blade 2 can rotate relative to the fan disc 1 within a certain range, and the fan blade 2 is automatically reset under the drive of the reset spring 3, which simplifies the installation structure between the fan blade 2 and the fan disc 1 and improves the assembly efficiency of the fan lamp.

[0045] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the fan blade 2 includes a fan blade body 21 and a mounting post 22 connected to the fan blade body 21, the mounting post 22 is arranged on one side of the fan blade body 21, one end of the mounting post 22 away from the fan blade body 21 is rotatably connected to the fan blade disk 1, and the limiting portion 23 is arranged on the side of the mounting post 22. In this way, the mounting post 22 is used as a structure rotatably connected to the fan blade disk 1, and the connection position of the fan blade 2 and the fan blade disk 1 can be clearly defined. The limiting portion 23 can extend toward the limiting groove 11 on the side of the mounting post 22, so that the limiting portion 23 is conveniently inserted into the limiting groove 11.

[0046] Specifically, a mounting column 22 can be selected to be set at one end of the fan blade body 21, and the mounting column 22 extends in a direction perpendicular to the extension direction of the fan blade body 21 toward a direction away from the fan blade body 21. A screw hole can be selected to be provided on the side surface of the mounting column 22 facing the fan blade disk 1, and a through hole is provided on the fan blade disk 1. Bolts are used to pass through the through hole on the fan blade disk 1 and are threadedly connected to the screw hole on the mounting column 22, so that the mounting column 22 is rotatably connected to the fan blade disk 1 through the bolts; of course, a bearing can also be selected to be provided on the first side surface of the fan blade disk 1, and the mounting column 22 is connected to the bearing, so that the mounting column 22 is rotatably connected to the fan blade disk 1.

[0047] The above-mentioned mounting column 22 is provided with a limiting portion 23 on the side surface parallel to the direction of the impeller disc 1, and the limiting groove 11 is arranged on one side of the connection point between the mounting column 22 and the impeller disc 1, so that the limiting portion 23 and the limiting groove 11 are arranged relative to each other in the axial direction of the impeller disc 1, so that the limiting portion 23 can be inserted into the limiting groove 11, and the limiting portion 23 can move in the limiting groove 11.

[0048] Reference Figure 1 , Figure 3 and Figure 6 As shown, in some embodiments, the limiting portion 23 includes a connecting block 231 and a limiting block 232 connected to the connecting block 231; the connecting block 231 is arranged on the side of the mounting column 22, and the limiting block 232 is arranged on the side of the connecting block 231 facing the limiting groove 11 in the axial direction of the impeller disk 1, the limiting block 232 is penetrated into the limiting groove 11, and the reset spring 3 is connected to one end of the limiting block 232 exposed on the second side surface.

[0049] With such an arrangement, after the mounting column 22 is rotationally connected to the impeller disc 1, the connecting block 231 extends in a direction parallel to the impeller disc 1 toward the direction of the limiting groove 11, so that the limiting block 232 on the connecting block 231 can be arranged relative to the limiting groove 11 in the axial direction of the impeller disc 1, so as to facilitate the insertion of the limiting block 232 into the limiting groove 11 and simplify the plug-in connection operation between the limiting portion 23 and the limiting groove 11.

[0050] Specifically, the connecting block 231 can be selected to be set on a side surface of the mounting column 22 parallel to the direction of the fan disk 1, the connecting block 231 extends in the direction away from the mounting column 22, and the limit block 232 is set at one end of the connecting block 231 away from the mounting column 22. The limit block 232 extends toward the fan disk 1 along the axial direction of the fan disk 1 on the connecting block 231, so that the limit block 232 can be inserted into the limit groove 11, so that the limit groove 11 limits the rotation angle of the mounting column 22 by limiting the moving distance of the limit block 232.

[0051] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, a ball 24 is provided on the side of the mounting post 22 facing the blade disc 1, and the ball 24 abuts against the blade disc 1. In this way, when the mounting post 22 rotates relative to the blade disc 1, the ball 24 rolls in the groove, reducing the friction between the mounting post 22 and the blade disc 1 when the mounting post 22 rotates.

[0052] 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.

[0053] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the blade disk 1 is provided with a mounting annular groove 13, which is arranged around the connection point between the mounting column 22 and the blade disk 1, and the ball 24 is rollingly connected in the mounting annular groove 13. In this way, the mounting annular groove 13 is 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 groove 13 when the mounting column 22 rotates, so that the mounting annular groove 13 limits the rolling trajectory of the ball 24, and improves the stability of the ball 24 when the mounting column 22 rotates.

[0054] Specifically, a circular groove is formed on one side surface of the impeller disk 1 facing the mounting column 22 as the mounting ring groove 13, 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 13, 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 13 in the axial direction of the impeller disk 1, so that the ball 24 can be inserted into the mounting ring groove 13, and the rotation of the mounting column 22 can drive the ball 24 to roll in the mounting ring groove 13.

[0055] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the number of balls 24 is multiple, and the multiple balls 24 are arranged at intervals along the direction around the connection point between the mounting column 22 and the fan blade disk 1, 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 force of the mounting column 22 rotating, 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.

[0056] 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.

[0057] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the fan blades 2 are rotatably connected to the fan blade disk 1 via a rotating shaft, the limiting groove 11 is an arc-shaped groove extending along the circumference of the rotating shaft, and the two ends of the limiting groove 11 along the circumference of the rotating shaft are respectively formed as a first groove wall 111 and a second groove wall 112, when the fan blades 2 are closed, the limiting portion 23 abuts against the first groove wall 111 for limiting, and when the fan blades 2 are unfolded, the limiting portion 23 abuts against the second groove wall 112 for limiting.

[0058] In this arrangement, the first groove wall 111 and the second groove wall 112 jointly limit the moving range of the limit portion 23, thereby achieving the effect of the limit groove 11 limiting the rotation angle of the fan blade 2, and the first groove wall 111 and the second groove wall 112 can determine the position of the fan blade 2 when it is closed and unfolded, thereby improving the accuracy of the position of the fan blade 2 when it rotates on the fan blade disk 1.

[0059] Specifically, a through hole can be set on the fan disk 1, and the mounting column 22 can be inserted into the through hole, so that the mounting column 22 is rotatably connected to the fan disk 1 as a rotating shaft. Of course, it is also possible to set a mounting hole 12 on the fan disk 1 for the fastener 4 to pass through, one end of the fastener 4 is connected to the fan blade 2, and the other end is rotatably connected to the mounting hole 12, so that the fastener 4 serves as a rotating shaft.

[0060] The above-mentioned limiting groove 11 is an arc-shaped groove, and the position when the fan blades 2 are closed can be selected as the closed position, and the position when the fan blades 2 are unfolded can be selected as the unfolded position. In the direction from the closed position to the unfolded position, the first groove wall 111 is arranged on one side of the second groove wall 112 in the direction from the closed position to the unfolded position.

[0061] Specifically, when the fan function needs to be turned off, the driving member 5 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 reset spring 3 overcomes the centrifugal force to reset the fan blades 2. The fan blades 2 are subjected to the elastic force applied by the reset spring 3 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 limiting portion 23 on the fan blades 2 abuts against the first groove wall 111 of the limiting groove 11, 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.

[0062] When the fan function is needed, the driving member 5 drives the fan disc 1 to rotate, and the rotating fan disc 1 applies 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 limiting portion 23 on the fan blades 2 abuts against the second groove wall 112 of the limiting groove 11, 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.

[0063] When the driving member 5 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 5 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 reset spring 3 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 limiting portion 23 on the fan blade 2 abuts against the first groove wall 111, and the fan blade 2 remains in a closed state.

[0065] With such arrangement, the plurality of limit grooves 11 can form limits on the limit parts 23 on the plurality of fan blades 2, and the plurality of reset springs 3 can respectively apply elastic force to the plurality of fan blades 2, so that when the fan disc 1 is stationary, the plurality of fan blades 2 are closed under the drive of the reset springs 3, and when the fan disc 1 rotates, the centrifugal force of the rotation of the fan disc 1 causes the plurality of fan blades 2 to overcome the elastic force of the corresponding reset springs 3 and unfold, so that the unfolded plurality of fan blades 2 simultaneously drive the air flow to realize the fan function of the fan lamp, and the plurality of fan blades 2 improves the efficiency of the fan lamp when blowing air, and the plurality of fan blades 2 can rotate independently of each other, which is convenient for cleaning and replacing a single fan blade 2 on the fan disc 1.

[0066] Specifically, the number of fan blades 2 and reset springs 3 can be selected to be three, and the three fan blades 2 are arranged at intervals along the circumference of the fan blade disk 1. The fan blade disk 1 is provided with three limit grooves 11, and the three reset springs 3 are respectively connected to the limit parts 23 of the three fan blades 2 through the three limit grooves 11; of course, the fan blades 2, reset springs 3 and limit grooves 11 can also be selected to be other numbers, and the number of fan blades 2, reset springs 3 and limit grooves 11 are equal. A limit groove 11 is provided around each position where the fan blades 2 are installed on the fan blade disk 1, so that the limit parts 23 on the multiple fan blades 2 can be inserted into the multiple limit grooves 11 one by one, and the multiple reset springs 3 are arranged one by one with the multiple fan blades 2, and each reset spring 3 can be connected to the limit part 23 of a fan blade 2 through a limit groove 11, so that the multiple reset springs 3 can apply elastic force to the multiple fan blades 2 respectively, so that the multiple reset springs 3 drive the multiple fan blades 2 to close.

In this way, the tension spring has a simple structure and low cost, and the fixing portion 14 can determine the connection position between the tension spring and the blade disc 1. The two ends of the tension spring are connected to the fixing portion 14 and the limiting portion 23 to apply elastic force to the blades 2 in the circumference of the blade disc 1, so that the tension spring drives the blades 2 to close.

[0068] Specifically, the fixing portion 14 can be selected to be a raised structure arranged on the fan disc 1, a through hole is arranged on the raised structure, hooks are arranged at both ends of the tension spring, and a through hole is arranged at one end of the limiting portion 23 located on the second side surface, the hooks at both ends of the tension spring are respectively connected with the through hole of the raised structure and the hook of the limiting portion 23, and the fixing portion 14 is on one side of the limiting groove 11 along the circumference of the fan disc 1, so that the tension spring is arranged along the circumference of the fan disc 1, so that when the fan blades 2 rotate, the tension spring can stretch and contract with the movement of the limiting portion 23, wherein when the fan blades 2 are closed, the tension spring is in a stretched state, and when the fan blades 2 are unfolded, the tension spring is further stretched, so that the tension spring always applies an elastic force to the fan blades 2 to drive the fan blades 2 to close.

[0069] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the driving member 5 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 starts to drive the fan disc 1 to rotate so that the fan blades 2 are unfolded, 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.

[0070] 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.

When the fan blades 2 need to be closed, the driving member 5 stops working and the fan disc 1 gradually stops rotating. The reset spring 3 drives the fan blades 2 to rotate toward the center of the fan disc 1, causing the fan blades 2 to gradually rotate toward the closed position and return to the closed position to complete the reset, thereby closing the fan blades 2.
