DETAILED DESCRIPTION

[0045] 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.

[0046] 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.

[0047] Reference Figures 1 to 10 As shown, some embodiments of the present invention provide a fan lamp, including a fan blade disc 1, fan blades 2, a driving member 6, a limiting member 3 and an elastic reset member 7.

[0048] The blades 2 are arranged on the blade disc 1 and are rotationally connected to the blade disc 1; the driving member 6 is connected to the blade disc 1, and the driving member 6 is configured to drive the blade disc 1 to rotate and drive the blades 2 to unfold relative to the blade disc 1. Specifically, the driving member 6 drives the blade disc 1 to rotate, and centrifugal force is generated. The blades 2 rotate relative to the blade disc 1 under the action of the centrifugal force, that is, the blades 2 are thrown away from the center of the blade disc 1 under the action of the centrifugal force to unfold the blades 2; after the blades 2 are unfolded relative to the blade disc 1, during the continuous rotation of the blade disc 1, the blades 2 are kept in the unfolded state under the action of the centrifugal force and rotate synchronously with the blade disc 1.

[0049] The limit member 3 and the fan blade 2 are arranged on the same side surface of the fan blade disk 1 and are connected to the fan blade 2 in transmission. A rotation limit portion is arranged on the limit member 3, and a limit matching portion is arranged on the fan blade disk 1. The rotation limit portion cooperates with the limit matching portion to limit the rotation angle of the fan blade 2 on the fan blade disk 1; the elastic reset member 7 is connected between the limit member 3 and the fan blade disk 1, and is configured to drive the limit member 3 to rotate, so as to drive the fan blade 2 to close relative to the fan blade disk 1 through the transmission cooperation between the limit member 3 and the fan blade 2, so as to close the fan blade 2.

[0050] It should be noted that in order to enable the fan blades 2 and the limit member 3 to rotate relative to the fan disk 1, a first mounting hole 12 and a second mounting hole 13 may be opened on the fan disk 1, the fan blades 2 are connected by a first fastener passed through the first mounting hole 12, and the limit member 3 is connected by a second fastener passed through the second mounting hole 13, so that the fan blades 2 and the limit member 3 can rotate relative to the fan disk 1 with the first fastener and the second fastener as the rotating axis respectively.

[0051] Furthermore, in order to realize that the blades 2 can be unfolded under the action of centrifugal force when the driving member 6 drives the impeller disk 1 to rotate, the blades 2 can be arranged at a position away from the center of the impeller disk 1, for example, the blades 2 are arranged at the edge of the impeller disk 1; the number of blades 2 can be multiple, for example, three, four, etc., and the multiple blades 2 are arranged at intervals along the circumference of the impeller disk 1 at the edge of the impeller disk 1. Exemplarily, the driving member 6 can be a driving mechanism such as a motor, and the driving member 6 can be connected to the center of the impeller disk 1, and the impeller disk 1 is driven to rotate by the driving mechanism such as a motor.

[0052] In specific implementation, the elastic reset member 7 is connected between the limit member 3 and the fan disk 1. In the process of the driving member 6 driving the fan disk 1 to rotate, the fan blades 2 are rotated relative to the fan disk 1 under the action of the centrifugal force, and drive the limit member 3 to rotate synchronously, so that the elastic reset member 7 connected between the limit member 3 and the fan disk 1 is deformed and stores elastic potential energy; in this way, when the driving member 6 stops driving, that is, after the driving member 6 stops providing the rotation function to the fan disk 1, the fan disk 1 will gradually slow down to stop rotating, and the centrifugal force generated by the rotation of the fan disk 1 will slowly decrease to disappear, and the elastic reset member 7 releases the elastic potential energy and restores the state before deformation, so that the limit member 3 rotates in the opposite direction relative to the fan disk 1 under the elastic force of the elastic reset member 7 and drives the fan blades 2 to close, thereby realizing the function of using the elastic reset member 7 to drive the fan blades 2 to reset, so that the fan blades 2 rotate relative to the fan disk 1 to the closed state.

[0053] By arranging a limit piece 3 on the fan disc 1, the limit piece 3 and the blades 2 are located on the same side surface of the fan disc 1, and the limit piece 3 is connected to the blades 2 in a transmission manner. During the process of the driving member 6 driving the fan disc 1 to rotate, a centrifugal force will be generated on the fan disc 1, thereby driving the blades 2 to unfold relative to the fan disc 1, so that the blades 2 can be unfolded when the fan function needs to be used, and the limit piece 3 is driven by the blades 2 to rotate synchronously with the blades 2; at the same time, a rotation limit portion is provided on the limit piece 3 for limiting the rotation angle of the blades 2 on the fan disc 1, and the rotation limit portion and the limit matching portion on the fan disc 1 cooperate with each other to limit the position of the blades 2 in the unfolded position and the closed position. Furthermore, the elastic reset member 7 is connected between the limit member 3 and the fan disc 1, and is configured to drive the fan blades 2 to close relative to the fan disc 1 through the limit member 3, so as to close the fan blades 2 when the fan function is not needed. The limit member 3 can provide an installation point or connection point for the elastic reset member 7. At the same time, the rotation limit portion is also arranged on the limit member 3. Such a setting can simplify the structure of the fan blades 2, thereby reducing the difficulty of assembling the fan blades 2.

[0054] In some embodiments, reference Figures 1 to 4 As shown, the fan blade 2 includes a fan blade body 23 and a mounting column 24 connected to one end of the fan blade body 23. The mounting column 24 is rotatably connected to the fan blade disk 1. Specifically, the mounting column 24 is connected by a first fastener passing through the first mounting hole 12 so that it can rotate relative to the fan blade disk 1, thereby driving the fan blade body 23 to rotate to expand or close the fan blade 2.

[0055] In specific implementation, a first meshing tooth 21 is provided on the outer circumference of the mounting column 24, and a second meshing tooth 31 is provided on the outer circumference of the limiting member 3. The first meshing tooth 21 and the second meshing tooth 31 are meshed for transmission, which has a buffering effect, so that the limiting member 3 and the fan blade 2 can smoothly transmit rotation and reduce abnormal noise when the limiting member 3 and the fan blade 2 rotate.

[0056] Reference Figure 7 and Figure 8 As shown, the second meshing tooth 31 is extended along the circumferential direction of the limit member 3, and the rotation limiting portion includes a limiting gap 32 arranged on the outer circumferential surface of the limit member 3 and the side facing away from the second meshing tooth 31. The limiting gap 32 is formed between the two end portions of the second meshing tooth 31. The two ends of the second meshing tooth 31 respectively correspond to the limit positions of the fan blades 2 when they are expanded and closed, so as to ensure that the fan blades 2 can move between the expanded position and the closed position. The rotation limiting portion is directly formed on the second meshing tooth 31, and there is no need to set an additional limiting structure. The limit member 3 has a simple structure, which can reduce the difficulty of assembling the limit member 3.

[0057] The limiting mating portion includes a limiting protrusion 11 arranged on the fan blade disk 1, and the limiting protrusion 11 is located in the limiting gap 32. When the fan blade 2 is unfolded, the limiting protrusion 11 abuts against the side of one end of the second meshing tooth 31 for limiting. When the fan blade 2 is closed, the limiting protrusion 11 abuts against the side of the other end of the second meshing tooth 31 for limiting. That is to say, the limiting protrusion 11 moves between the two ends of the second meshing tooth 31, and can abut against the two ends of the second meshing tooth 31 respectively during movement, thereby achieving limiting.

[0058] It should be noted that the rotation limiting portion and the limiting matching portion may also be other structures, and the present invention does not limit this, as long as they can limit the position of the fan blade 2 when it is unfolded and closed.

[0059] In some embodiments, reference Figure 7 As shown, a mounting groove 33 is provided on one side surface of the limit member 3 facing the fan disk 1, and the elastic reset member 7 is arranged in the mounting groove 33, that is, the mounting groove 33 for installing the elastic reset member 7 is provided by the limit member 3, so that the limit member 3 and the fan blade 2 are driven to close by the elastic reset member 7, and there is no need to set up any redundant structure on the fan blade 2. One end of the elastic reset member 7 is connected to the inner groove wall of the mounting groove 33, and the other end is connected to the fan disk 1, so as to drive the limit member 3 to move relative to the fan disk 1.

[0060] In specific implementation, the elastic reset member 7 is a reset torsion spring. When the fan blade 2 is expanded by the centrifugal force, the limit member 3 rotates synchronously with the fan blade 2 to drive the reset torsion spring to undergo elastic deformation, and the fan blade 2 can maintain a certain angle of rotation to deliver air. When the driving member 6 stops driving, the fan disc 1 gradually slows down to stop rotating, and the centrifugal force on the fan blade 2 gradually decreases and disappears. The reset torsion spring recovers its deformation and drives the limit member 3 to move. The fan blade 2 gradually closes with the rotation of the limit member 3, and then the fan blade 2 is hidden in the fan disc 1. That is, when the fan function of the fan lamp of the utility model is not in use, the fan blade 2 can be automatically recovered, and the fan lamp is more beautiful as a whole.

[0061] Reference Figure 8 As shown, two adjacent and spaced limiting ribs 331 are provided on the inner groove wall of the installation groove 33, and an insertion gap is formed between the two limiting ribs 331. One end of the reset torsion spring is limited in the insertion gap. A raised limiting rib 14 is formed on the surface of the blade disc 1 facing the blade 2. A limiting socket is formed between the limiting rib 14 and the blade disc 1, and the other end of the reset torsion spring is limited in the limiting socket. When the blade 2 is unfolded, one end of the reset torsion spring is limited in the limiting socket, and the limiting rib 331 can apply a torsion force to the other end of the reset torsion spring, thereby causing the reset torsion spring to deform and store elastic potential energy. When the blade 2 is closed, the reset torsion spring releases the elastic potential energy, and the other end of the reset torsion spring returns to the state before deformation, and drives the limiting rib 331 and the limiting member 3 to rotate.

[0062] In some embodiments, reference Fig.10 As shown, a first convex point structure 22 is provided on the surface of the blade 2 facing the blade disk 1, and the first convex point structure 22 contacts the surface of the blade disk 1; Figure 7 As shown, the second convex point structure 34 is provided on the surface of the side of the stopper 3 facing the blade disk 1, and the second convex point structure 34 contacts the surface of the blade disk 1. It can be understood that the contact area between the first convex point structure 22 and the second convex point structure 34 and the blade disk 1 is relatively reduced, and the blades 2 and the stopper 3 can slide smoothly on the blade disk 1, thereby reducing the resistance and noise when the blades 2 are unfolded and closed, and improving the user experience.

[0063] Specifically, the first protrusion structure 22 and the second protrusion structure 34 can be three, four or more, so that a first rotation plane is jointly determined by multiple first protrusion structures 22, so that the fan blade 2 can rotate smoothly, and a second rotation plane is jointly determined by multiple second protrusion structures 34, so that the limit member 3 can rotate smoothly.

[0064] In some embodiments, reference Figure 2 and Figure 4 As shown, the fan lamp of the utility model also includes a first auxiliary member 4 and a second auxiliary member 5; the first auxiliary member 4 is arranged on the side of the fan disc 1 away from the fan blade 2, the first auxiliary member 4 is connected to the fan blade 2 and rotates synchronously to reduce the friction force when the fan blade 2 rotates; the second auxiliary member 5 is arranged on the side of the fan disc 1 away from the limit member 3, the second auxiliary member 5 is connected to the limit member 3 and rotates synchronously to reduce the friction force when the limit member 3 rotates.

[0065] It can be understood that the fan blades 2 and the limiting member 3 are arranged on one side surface of the fan blade disc 1, and the first auxiliary member 4 and the second auxiliary member 5 are arranged on the other side surface of the fan blade disc 1, that is, the fan blades 2 and the limiting member 3 are arranged on different sides of the fan blade disc 1. This can avoid the first auxiliary member 4 and the second auxiliary member 5 from interfering with the movement of the fan blades 2 and the limiting member 3, thereby ensuring that the fan blades 2 can be stably unfolded and closed.

[0066] Reference Fig. 9 As shown, the first auxiliary member 4 is provided with a third convex point structure 41 on one side of the surface facing the blade disk 1, and the third convex point structure 41 contacts the surface of the blade disk 1; and / or the second auxiliary member 5 is provided with a fourth convex point structure 51 on one side of the surface facing the blade disk 1, and the fourth convex point structure 51 contacts the surface of the blade disk 1. It can be understood that the contact area between the third convex point structure 41 and the fourth convex point structure 51 and the blade disk 1 is relatively reduced, and the first auxiliary member 4 and the second auxiliary member 5 can slide smoothly on the blade disk 1, thereby reducing the resistance and noise when the blades 2 are unfolded and closed, and improving the user experience.

[0067] Specifically, the third protrusion structure 41 and the fourth protrusion structure 51 can be three, four or more, so that a third rotation plane is jointly determined by multiple third protrusion structures 41, so that the first auxiliary member 4 can rotate smoothly, and a fourth rotation plane is jointly determined by multiple fourth protrusion structures 51, so that the second auxiliary member 5 can rotate smoothly.

[0068] In specific implementation, the first convex point structure 22, the second convex point structure 34, the third convex point structure 41 and the fourth convex point structure 51 can be integrally formed convex points or ball bearing structures, and the present disclosure does not limit this, as long as the contact area with the blade disk 1 can be reduced to reduce the resistance and noise when the blades 2 are unfolded and closed. Further, the surfaces of the first convex point structure 22, the second convex point structure 34, the third convex point structure 41 and the fourth convex point structure 51 are formed as spherical surfaces to form point contact with the surface of the blade disk 1, so as to further reduce the contact area with the blade disk 1, increase the smoothness of the rotation of the blades 2, and avoid noise.

[0069] In some embodiments, reference Figure 5 and Figure 6 As shown, a first mounting hole 12 is opened on the fan disc 1, and the fan blade 2 and the first auxiliary member 4 are connected by a first fastener penetrating through the first mounting hole 12, so that the fan blade 2 and the first auxiliary member 4 can rotate relative to the fan disc 1 with the first fastener as the rotating axis. In other words, the fan blade 2 and the first auxiliary member 4 can be connected by a first fastener such as a screw or bolt, so that the fan blade 2 and the first auxiliary member 4 can rotate synchronously.

[0070] Furthermore, a second mounting hole 13 is opened on the impeller disc 1, and the limit member 3 and the second auxiliary member 5 are connected by a second fastener passing through the second mounting hole 13, so that the limit member 3 and the second auxiliary member 5 can rotate relative to the impeller disc 1 with the second fastener as the rotating axis. That is to say, the limit member 3 and the second auxiliary member 5 can be connected by a second fastener such as a screw or bolt, so that the limit member 3 and the second auxiliary member 5 can rotate synchronously.

[0071] In some embodiments, reference Figure 1 and Figure 3 As shown, there are multiple blades 2, and multiple blades 2 are arranged at intervals along the circumference of the blade disk 1; there are multiple limiters 3, and multiple limiters 3 are arranged one-to-one with multiple blades 2, and multiple limiters 3 are respectively connected to the corresponding blades 2 in a transmission manner; there are multiple elastic reset members 7, and an elastic reset member 7 is connected between each limiter 3 and the blade disk 1. In other words, each blade 2 can be individually arranged corresponding to the corresponding limiter 3 and the elastic reset member 7 to realize the expansion or closure separately, which is convenient for operation during assembly and later maintenance, and the blades 2, the limiters 3 and the elastic reset member 7 can be replaced or cleaned separately.

[0072] Reference Figure 1 and Figure 3 As shown, a driving member 6 is connected to the blade disc 1, and the driving member 6 is used to drive the blade disc 1 to rotate. When the blades 2 are closed, an installation space for installing the driving member 6 is formed on the inner side of the blades 2 to avoid motion interference between the driving member 6 and the blades 2. Specifically, the driving member 6 can be fixed to the blade disc 1 by fasteners such as screws and bolts to drive the blade disc 1 to rotate and generate centrifugal force to drive the blades 2 to unfold. Specifically, the driving member 6 is a motor. When the fan function needs to be used, the motor drives the blade disc 1 to rotate so that the blades 2 are thrown out in a direction away from the center of the blade disc 1 under the action of centrifugal force to achieve air supply; when the fan function needs to be turned off, the motor stops driving, that is, the motor stops providing rotational kinetic energy to the blade disc 1, the blade disc 1 gradually slows down to stop rotating, the centrifugal force slowly decreases to disappear, and the elastic reset member 7 overcomes the centrifugal force to reset the blades 2 to close the blades 2.
