Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The technical solutions disclosed in the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 13, an embodiment of the present invention discloses a fan lamp, which includes a lamp panel 100, a lamp assembly 200, a fan assembly 300, a motor assembly 400, and a top mounting assembly 500.

The lamp assembly 200 is disposed on one side of the lamp panel 100, the fan assembly 300 is disposed on one side of the lamp panel 100 facing away from the lamp assembly 200, the motor assembly 400 includes a dc motor 410, and the fan assembly 300 is configured to rotate under the driving of the dc motor 410. The fan assembly 300 can perform a blowing function and the lamp assembly 200 can perform illumination, thereby making the fan lamp more functional.

This fan lamp utilizes direct current motor 410 drive fan assembly 300 to rotate, need not to use additional parts such as electric capacity, motor cover, simplifies motor assembly 400's structure, reduces motor assembly 400's volume to reduce the whole volume of fan lamp, make the structure of fan lamp cleaner and tidier, pleasing to the eye, improve user's use and experience.

In an alternative embodiment, the fan assembly 300 may include a rotating plate 330, a plurality of fan blades 310 and a synchronizing member 320, the fan blades 310 have a mounting end and a free end, the mounting end has a mounting portion 311 and a connecting portion 312 spaced from each other, the mounting portion 311 is mounted on the rotating plate 330 through a first rotating connecting portion 313, the fan blades 310 can rotate around a central axis M of the first rotating connecting portion 313, and the connecting portion 312 is mounted on the synchronizing member 320 through a second rotating connecting portion 314, such that the plurality of fan blades 310 can be synchronously switched between the storage position and the deployment position. Optionally, the number of the fan blades 310 may be four, and the four fan blades 310 may be uniformly arranged, and of course, the number of the fan blades 310 may also be other values, which is not limited in the embodiment of the present invention. When the fan blades 310 are in the storage position, the fan blades 310 retract relative to the rotating disc 330, and the rotating disc 330 and the fan blades 310 do not rotate; when the fan blades 310 are in the unfolded position, the fan blades 310 are extended relative to the rotating disc 330, and the fan blades 310 rotate along with the rotation of the rotating disc 330, so that the blowing is realized. Optionally, the synchronizing member 320 is provided with a plurality of sliding grooves, the second rotating connecting portions 314 are provided with protruding portions, and the protruding portions of the second rotating connecting portions 314 are in one-to-one sliding fit with the sliding grooves. When the rotating disc 330 rotates, the synchronous member 320 rotates therewith, and the fan blades 310 can be synchronously unfolded by the plurality of sliding grooves and the plurality of protrusions, and finally reach the unfolded position. The synchronous member 320 can more reliably realize synchronous rotation of the fan blades 310, thereby overcoming the influence of processing errors, assembly errors and other factors, so that the heat dissipation effect of the fan assembly 300 can more reliably approach the design value, and the blowing effect thereof can be improved. Simultaneously, this structure can also make the effort of fan lamp distribute more evenly, prevents that the fan lamp from appearing rocking because of the effort maldistribution.

In one embodiment, a direction parallel to the central axis M is defined as a first direction, and when the fan blade 310 is in the storage position, an orthogonal projection of the fan blade 310 along the first direction is located within an orthogonal projection of the lamp panel 100 along the first direction. That is, in this state, the edge of the fan blade 310 does not exceed the edge of the lamp panel 100, so that the space occupied by the fan blade 310 in this state is as small as possible, thereby optimizing the compactness of the fan lamp.

To better effect the return of the fan blade 310, the fan assembly 300 may further include a return spring 350, one end of the return spring 350 is connected to the turntable 330, and the other end of the return spring 350 is connected to the fan blade 310. When the fan blade 310 is unfolded, the return spring 350 is deformed by the acting force from the fan blade 310, when the fan assembly 300 finishes working, the centrifugal force applied to the fan blade 310 disappears, the acting force of the fan blade 310 on the return spring 350 disappears, and the return spring 350 can be deformed again, so that a reaction force is applied to the fan blade 310, and the fan blade 310 retracts relative to the rotating disc 330 until the fan blade 310 retracts to the right position. The return spring 350 may be a torsion spring, which may be installed at the installation part 311, and occupies a small space, thereby being more advantageous to implement a compact design of the fan lamp.

Alternatively, the dc motor 410 includes a motor main body 411 and a motor shaft 412, the motor main body 411 is fixedly mounted to the turntable 330, and the motor shaft 412 is fixed relative to the lamp panel 100. When the dc motor 410 is powered on, the motor shaft 412 is fixed, and the motor body 411 rotates relative to the motor shaft 412, so as to drive the turntable 330 to rotate, thereby unfolding the fan blades 310. This kind of scheme passes through motor main body 411 and drives the carousel 330 and rotate, and motor main body 411 is more stable when rotating, and its ability of bearing the effort is stronger, therefore this kind of direct current motor 410's transmission efficiency is higher, and its life is longer.

In one embodiment, the fan lamp includes a top mount assembly 500, and the top mount assembly 500 is used to enable connection between the fan lamp and a mounting base (e.g., a roof) to enable mounting of the fan lamp. The motor assembly 400 is disposed on a side of the turntable 330 facing away from the lamp panel 100, the top mounting assembly 500 is disposed on a side of the motor assembly 400 facing away from the turntable 330, the top mounting assembly 500 includes a hanging cup 530 and a hanging rod 520, one end of the hanging rod 520 is connected to the hanging cup 530, and the other end of the hanging rod 520 is fixed to the motor shaft 412. The length of the boom 520 can be flexibly set, and optionally, the boom 520 can adopt a multi-section structure, so that a user can adjust the length of the boom 520 according to the requirement of the user, and the installation height of the fan lamp can be changed. When the suspension rod 520 is directly and fixedly connected with the motor shaft 412, the whole fan lamp is simpler in structure and more compact in structure.

When the fan lamp includes the top mount assembly 500 and the top mount assembly 500 includes the hanger bar 520, the motor assembly 400 may include a connector 440 and a first decorative cover 420, the connector 440 connecting the hanger bar 520 and the motor shaft 412, the first decorative cover 420 covering the outside of the connector 440. Alternatively, one end of the connector 440 may be inserted into the hanger rod 520, and one end of the motor shaft 412 may be inserted into the connector 440, which is more convenient to operate, and the connector 440 may be detachable from the hanger rod 520, thereby facilitating maintenance of the fan lamp. The first decorative cover 420 may shield the connector 440 from the external environment, thereby improving the aesthetic appearance of the fan lamp, and at the same time, when the user needs to detach the hanger bar 520 and the connector 440, the first decorative cover 420 must be removed first, thereby reducing the risk of the hanger bar 520 and the connector 440 being detached by mistake. Alternatively, in order to simplify the attaching and detaching operation of the first trim cover 420, the first trim cover 420 may be fitted on the outside of the boom 520, may be flexibly moved with respect to the boom 520, and may cover the link 440 and the like under the self-gravity.

Further, the fan assembly 300 further includes a fixing ring 340, the fixing ring 340 is fixedly mounted on the turntable 330, the motor main body 411 is fixedly mounted on the fixing ring 340, the synchronizer 320 is in a ring shape, the synchronizer 320 is sleeved outside the fixing ring 340, and a limiting structure (not shown) is arranged between the synchronizer 320 and the fixing ring 340, the limiting structure includes an expansion limiting portion and a storage limiting portion, the expansion limiting portion can limit the fan blade 310 at the expansion position, and the storage limiting portion can limit the fan blade 310 at the storage position. The synchronizer 320 can rotate relative to the fixing ring 340, when the synchronizer 320 is matched with the expansion limiting part, the synchronizer 320 cannot rotate continuously, so that the fan blades 310 are kept at the expansion position; similarly, when the synchronization member 320 is engaged with the receiving position-limiting portion, the synchronization member 320 cannot rotate continuously, so that the fan blade 310 is kept at the receiving position. With the expansion limiting part and the accommodation limiting part, the fan blade 310 can be more reliably kept at the expansion position and the accommodation position, and the fan blade 310 is prevented from being mistakenly operated due to other external forces.

The expansion limiting part and the storage limiting part can be clamped to realize the relative positioning between the synchronizing member 320 and the fixing ring 340, and other manners can be adopted.

Alternatively, the fan lamp may further include a fixing plate 600, the fixing plate 600 is fixedly mounted to the motor shaft 412, and the lamp panel 100 is fixedly mounted to the fixing plate 600, that is, the motor shaft 412 may be connected to the lamp panel 100 through the fixing plate 600, and the fixing plate 600 is located between the fan assembly 300 and the lamp panel 100. Because the fan assembly 300 rotates during operation and the lamp panel 100 is fixed, the fan assembly 300 and the lamp panel 100 can be better separated by the fixing disc 600, and the fan assembly 300 can be prevented from driving the lamp panel 100 to rotate, thereby achieving the purpose of improving the reliability of the fan lamp during operation. Further, the fixing plate 600 may abut against the lamp panel 100, so as to better limit the shaking of the lamp panel 100, prevent the lamp panel 100 from slightly swinging due to the movement of the fixing plate 600, and thus improve the user experience when using the fan lamp.

Optionally, the fan lamp further includes a bushing 430 sleeved on the motor shaft 412, and the bushing 430 is located between the motor body 411 and the fixing plate 600. The sleeve 430 may better separate the motor body 411 from the fixing plate 600, thereby further improving the stability of the fan lamp during operation.

The above-mentioned dc motor 410 may be hidden relative to the fan assembly 300, and specifically, the dc motor 410 may be covered by a motor cover, but this structure may result in a large number of components of the fan lamp, which results in a high cost of the fan lamp, and the weight of the fan lamp may also increase accordingly. Based thereon, the dc motor 410 may be configured to be at least partially exposed with respect to the fan assembly 300. This direct current motor 410's security is higher, therefore even direct current motor 410 is at least partly for fan assembly 300 exposes, can not bring the potential safety hazard yet, and meanwhile, this embodiment cancels structures such as motor cover and establishes in direct current motor 410 outside to reduce the spare part that the fan lamp contains, thereby reduce the cost and the weight of fan lamp, can suitably reduce the height of fan lamp simultaneously, make the whole light and handy of fan lamp.

After the structure is adopted, when the fan lamp is observed along the height direction (namely the direction parallel to the central axis M), the edge of the lamp panel 100 does not exceed the edge of the lamp shade 210, and meanwhile, the edge of the lamp shade 210 does not exceed the edge of the lamp panel 100, so that the structure of the whole fan lamp is more compact and simpler, and the attractiveness of the fan lamp is higher.

Further, the lamp panel 100 may include a bottom plate 120 and a circumferential plate 130, the lamp cover 210 includes a lamp cover body 212 and an annular mounting portion 213, the lamp cover circumferential outer wall 211 is located at an outer periphery of the lamp cover body 212, the lamp panel circumferential outer wall 110 is located at an outer periphery of the circumferential plate 130, the annular mounting portion 213 is sleeved at an inner side of the circumferential plate 130, and the annular mounting portion 213 is fastened to the lamp panel 100. On one hand, when the annular mounting portion 213 is sleeved on the inner side of the circumferential plate 130, the annular mounting portion 213 and the circumferential plate 130 can generate a limiting effect in the radial direction (i.e., the direction perpendicular to the central axis M) of the annular mounting portion 213, so that the strength of the lamp panel 100 and the lamp cover 210 after connection is higher; on the other hand, the annular mounting portion 213 is connected to the lamp panel 100 in a snap-fit manner, so that the assembly and disassembly operations of the fan lamp can be simplified, and the maintenance of the fan lamp is facilitated.

The connection between the clamping member 230 and the lamp housing 210 can be realized by the matching between the clamping protrusion 214 and the clamping groove 235, so that the assembly of the lamp panel 100 and the lamp housing 210 is completed. In this embodiment, the screw mounting portion 236 can improve the connection strength between the clip 230 and the lamp panel 100, and meanwhile, the clip operation can be simplified by the cooperation of the clip protrusion 214 and the clip groove 235 to realize the clip, and the clip strength can be improved.

Further, at least one of the clamping protrusion 214 and the clamping member 230 may be provided with a guiding structure 260, and the guiding structure 260 may guide the clamping process of the clamping protrusion 214 and the clamping member 230, and also may enable the clamping protrusion 214 and the clamping member 230 to be clamped and matched more smoothly.

In an alternative embodiment, the guiding structure 260 includes a first guiding inclined surface 2141 disposed on the clamping protrusion 214 and a second guiding inclined surface 2341 disposed on the clamping member 230, wherein, along the circumferential direction of the annular mounting portion 213, the first guiding inclined surface 2141 is located on the end surface of the clamping protrusion 214, and the second guiding inclined surface 2341 is located on the side of the clamping member 230 close to the first guiding inclined surface 2141. Alternatively, the first guiding inclined surface 2141 and the second guiding inclined surface 2341 may be both obliquely arranged flat surfaces or smooth curved surfaces. In the process of clamping the clamping protrusion 214 and the clamping member 230, the first guiding inclined surface 2141 and the second guiding inclined surface 2341 are slidably engaged with each other, so as to achieve the guiding function, and the guiding structure 260 has the advantages of simple structure and good guiding effect.

221a and 221b are disposed at the edge of the substrate 221 such that the first and

second bonding portions

221a and 221b do not occupy too much space of the substrate 221, so as to dispose the LED light source 222 on the substrate 221.

Further, in order to simplify the assembling operation of the lamp assembly 200, the first and

second coupling portions

221a and 221b may be connected to the coupling member 223 by a screw connection.

In an alternative embodiment, a distance between an end of the lamp panel 100 facing away from the lamp housing 210 and an end of the lamp housing 210 facing away from the fan assembly 300 along a thickness direction of the lamp panel 100 is a first distance L1, and a maximum distance between two opposite ends of the lamp panel circumferential outer wall 110 along a length direction of the lamp panel 100 is a second distance L2, wherein a ratio of the first distance L1 to the second distance L2 is less than or equal to 0.165. So configured, the first distance L1 can be set as small as possible, so that the overall height of the fan lamp is smaller, thereby improving the decorativeness of the fan lamp.

In one embodiment, the fan lamp further includes a top mounting assembly 500 and a driver 540, and the driver 540 is mounted to the top mounting assembly 500, the fan assembly 300, or the lamp assembly 200, that is, the driver 540 may be mounted by using the structure of the top mounting assembly 500, the fan assembly 300, or the lamp assembly 200, so that the driver 540 occupies a smaller space, or even no space, so that the fan lamp is more compact. In an alternative embodiment, the driver 540 is electrically connected to at least one of the fan assembly 300 and the lamp assembly 200, thereby enabling driving of at least one of the fan assembly 300 and the lamp assembly 200. When the driver 540 is electrically connected to the lamp assembly 200, the lamp assembly 200 can be driven to emit light, thereby realizing the lighting function of the fan lamp. When the driver 540 is electrically connected to the fan assembly 300, the fan assembly 300 can be driven to unfold and store, and the unfolded fan assembly 300 can be driven to rotate, so as to achieve the blowing function of the fan lamp. When the driver 540 is electrically connected to the fan assembly 300 and the lamp assembly 200 at the same time, the fan assembly 300 can be driven to rotate and the lamp assembly 200 can emit light at the same time, so that the blowing function and the lighting function of the fan lamp can be realized at the same time.

Further, the driver 540 may be configured to be electrically connected to both the dc motor 410 and the lamp assembly 200. At this time, the drivers 540 may be integrated, and the same driver 540 may simultaneously supply power to the dc motor 410 and the lamp assembly 200, so that the number of drivers 540 required is naturally reduced. Alternatively, the driver 540 may be provided as one, and when the power consumption of the fan lamp is large, two or more drivers 540 may be provided, and each driver 540 is configured to be electrically connected to the dc motor 410 and the lamp assembly 200 at the same time. The structure enables the fan assembly 300 and the lamp assembly 200 to be driven by the same driver 540, and compared with a mode that the fan assembly 300 and the lamp assembly 200 are driven by respective drivers, the number of parts of the fan lamp disclosed by the embodiment of the invention is reduced, so that the space occupied by the fan lamp is smaller, and the fan lamp is convenient to transport.

In an alternative embodiment, the top mount assembly 500 may include a second trim cover 510, the second trim cover 510 having a mounting cavity in which the actuator 540 is mounted. At this time, the driver 540 is installed using the installation cavity in the second trim cover 510, and the driver 540 does not substantially occupy an additional space, thereby making the structure of the fan lamp more compact.

In another embodiment, the lamp assembly 200 has an optical cavity in which the driver 540 is mounted. The optical cavity here is larger in space and therefore more convenient for positioning the driver 540. Meanwhile, if the driver 540 needs to be detached, the driver 540 can be directly seen only by opening the lamp assembly 200 (specifically, the lamp cover 210 can be detached), so that the structure is more convenient for maintaining the driver 540.

As mentioned above, the fan assembly 300 may include a plurality of fan blades 310, and as shown in fig. 14 to 22, in an alternative embodiment, the number of the fan blades 310 is two, and relatively speaking, the weight of the two fan blades 310 is light, so that the weight of the whole fan lamp can be reduced appropriately, and the number of parts of the fan lamp can be reduced, which facilitates the assembly of the fan lamp.

The fan blade 310 may have an inner edge line 315 and an outer edge line 316, the inner edge line 315 being an edge line of a side of the fan blade 310 close to the dc motor 410, and the outer edge line 316 being an edge line of a side of the fan blade 310 away from the dc motor 410. Optionally, in order to improve the blowing effect of the fan assembly 300, along the extending direction of the fan blades 310, the vertical distance between the inner edge line 315 and the lamp panel 100 gradually increases and then gradually decreases. The vertical distance here refers to a dimension in a direction perpendicular to the lamp panel 100. The structure enables the area of the fan blade 310 to be gradually increased and then gradually decreased, so as to generate a larger disturbance effect on the air flow, thereby achieving the purpose of improving the blowing effect, and meanwhile, the area of the fan blade 310 is gradually decreased, so that the size of the fan blade 310 can be properly reduced, and the weight of the fan blade 310 is reduced.

In a further alternative embodiment, the inner edge line 315 may be higher than the outer edge line 316, so that the windward side of the fan blade 310 has a larger area, thereby achieving the purpose of improving the blowing effect.

It is understood that the inner edge line 315 has a highest point, and referring to fig. 17 and 21, a vertical distance h between the highest point and the outer edge line 316 is (0.15-0.3) × r, where r is a distance between the outer edge line 316 and a rotation center of the fan assembly 300 when the fan blade 310 is in the storage position, and the distance may be a maximum distance. That is to say, when the fan blades 310 are located at the storage position, and the distance between the outer edge line 316 and the rotation center of the fan assembly 300 is different, the position of the highest point of the inner edge line 315 may also be different, so as to flexibly adjust the area of the windward side of the fan blades 310 according to the size of the fan blades 310, thereby optimizing the blowing effect of the fan lamp.

As previously mentioned, fan blade 310 has a free end that is optionally provided with a counterweight structure 317 as shown in fig. 23 and 24. After the counterweight structure 317 is added, the weight of the free end of the fan blade 310 is increased, and the stability of the whole fan blade 310 is higher during the rotation of the fan blade 310. The position of the counterweight structure 317 may be on the side of the outer edge line 316, but considering that the side of the inner edge line 315 is more prone to vibrate, the counterweight structure 317 may be on the side of the inner edge line 315, so that the fan blade 310 rotates more stably.

The weight structure 317 may be a weight separately mounted on the fan blade 310, or may be integrally provided with the fan blade 310. To facilitate assembly of the fan lamp and to prolong the service life of the weight structure 317, the weight structure 317 may be integrated with the fan blade 310. At this time, the position of the weight structure 317 may be the position where the thickness of the fan blade 310 is the largest. That is, the local thickness of the free end of the fan blade 310 may be increased to form the weight structure 317.

As mentioned above, the fan blades 310 can rotate around the central axis M of the first rotating connection 313, when the number of the fan blades 310 is two, the central axis M of the first rotating connection 313 of one fan blade 310 is a first axis, the central axis M of the first rotating connection 313 of the other fan blade 310 is a second axis, and the first axis, the second axis and the rotating axis of the rotating disc 330 are coplanar. That is, the rotation centers of the two fan blades 310 are symmetrically distributed at both sides of the rotation center of the turntable 330, so that the entire fan lamp is more stable in structure and operates more stably.

The portion of the fan blades 310 extending from the mounting portion 311 to the free end may be defined as a fan body 318, and in order to further control the height of the fan lamp, in the accommodating position, the fan body 318 of one fan blade 310 and the fan body 318 of the other fan blade 310 are not overlapped with each other, so as to avoid the situation that the height of the fan lamp is increased after the two fan blades 310 are overlapped in a large area, and thus the fan lamp is more compact.

In the above embodiments of the present invention, the difference between the embodiments is mainly described, and different optimization features between the embodiments can be combined to form a better embodiment as long as they are not contradictory, and further description is omitted here in view of brevity of the text.

The above description is only an example of the present invention, and is not intended to limit the present invention. Various modifications and alterations to this invention will become apparent to those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
