[0054] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0055] Here, it should be noted that, in order to avoid the present application being obscured by unnecessary details, only structures and / or processing steps closely related to the solution of the present application are shown in the accompanying drawings, and other details not closely related to the present application are omitted.

[0056] In addition, it should also be noted that the term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0057] The technical solutions disclosed in the various embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0058] As shown in Figures 1-11 The embodiment of the present application discloses a driving motor 100 applied to a fan lamp to provide power for the fan lamp. The driving motor 100 drives the fan blade 400 to rotate, and the fan blade 400 drives the air flow, thereby realizing the heat dissipation performance of the fan lamp.

[0059] The driving motor 100 comprises a first shell 110, a second shell 120 and a motor shaft 130, the motor shaft 130 penetrates the first shell 110 and the second shell 120 along the height direction, and the first shell 110 and the second shell 120 can rotate around the motor shaft 130. The first shell 110 and the second shell 120 constitute the shell of the driving motor 100. The first shell 110 comprises a central region 111 combined with the second shell 120 and a fan mounting disc region 112 extending from the edge of the central region 111 to the direction away from the motor shaft 130 and beyond the covering area of the second shell 120, and the fan blades 400 of the fan lamp are assembled on the fan mounting disc region 112 and located on the side of the first shell 110 away from the second shell 120. The second shell 120 rotates under the action of the rotor assembly 140 of the driving motor 100, drives the first shell 110 to rotate, and further drives the fan blades 400 to rotate. By directly assembling the fan blades 400 on the first shell 110 of the driving motor 100, the first shell 110 can not only constitute the shell of the driving motor 100 with the second shell 120, but also drive the fan blades 400 to rotate, so that the fan lamp does not need to separately set the shell of the driving motor 100 and the rotating disc of the fan blades 400, and the shell of the motor and the rotating disc of the traditional fan lamp are combined, which correspondingly reduces the parts of the fan lamp, saves materials to a certain extent, reduces the complexity of the assembly of the parts, reduces the assembly difficulty of the fan lamp, and can also avoid the assembly error generated when the motor and the rotating disc are assembled. At the same time, by integrating the first shell 110 of the driving motor 100 and the rotating disc, the fan lamp can also have a more neat and integrated appearance.

[0060] In addition, since the fan mounting disc region 112 exceeds the covering area of the second shell 120, the fan blades 400 are far away from the second shell 120 when installed, so that the fan blades 400 and the second shell 120 are not easy to interfere with each other when installed.

[0061] Further, the first shell 110 is provided with a first sleeve part 116, the second shell 120 is provided with a second sleeve part 122 corresponding to the position of the first sleeve part 116, and the first shell 110 and the second shell 120 are matched and connected through the first sleeve part 116 and the second sleeve part 122. By setting the first sleeve part 116 and the second sleeve part 122, the first shell 110 and the second shell 120 of the driving motor 100 can be accurately positioned and connected to avoid the assembly gap error caused by screwing.

[0062] In a preferred embodiment, the central region 111 of the first shell 110 is provided with a protrusion extending towards the second shell 120, and the second shell 120 is provided with a through hole corresponding to the protrusion, the through hole is sleeved on the protrusion, and the first shell 110 and the second shell 120 are fixedly connected by a self-riveting process. At the same time, the first sleeve part 116 and the second sleeve part 122 are wrapped in the recessed structure of the first shell 110, so as to improve the appearance of the fan lamp. In other embodiments, the protrusion can also be provided on the side of the second shell 120 close to the first shell 110, and the first shell 110 is provided with a through hole corresponding thereto, and the first shell 110 and the second shell 120 are fixedly connected by a self-riveting process. The present application is not limited in this regard.

[0063] The second shell 120 and the first shell 110 can rotate around the motor shaft 130. In a specific operation process, the second shell 120 rotates relative to the motor shaft 130, the second shell 120 drives the first shell 110 to rotate, and the first shell 110 drives the fan blade 400 to rotate. Alternatively, the driving motor 100 can be an external rotor motor, of course, the driving motor 100 can also be an internal rotor motor. This is not limited in this regard.

[0064] In a preferred embodiment, the driving motor 100 is an external rotor motor, and the driving motor 100 includes a first shell 110, a second shell 120, a motor shaft 130, and a rotor assembly 140. The rotor assembly 140 is accommodated in the accommodation space 160 formed between the central region 111 of the first shell 110 and the second shell 120, and the rotor assembly 140 is sleeved on the motor shaft 130. The rotor assembly 140 includes a motor rotor 141 and a winding group 142, and the motor rotor 141 is arranged around the side of the winding group 142 away from the motor shaft 130. By accommodating the rotor assembly 140 in the accommodation space 160, the rotor assembly 140 can be protected, and dust can be prevented from entering the rotor assembly 140 to affect the performance of the rotor assembly 140.

[0065] The driving motor 100 further includes a first bearing 151 and a second bearing 152, both of which are accommodated in the accommodation space 160 and sleeved on the motor shaft 130. The central region 111 is recessed on the side away from the second shell 120 along the height direction to form a first accommodating groove 115, and the first bearing 151 is located in the first accommodating groove 115. The second shell 120 is recessed on the side away from the central region 111 along the height direction to form a second accommodating groove 121, and the second bearing 152 is located in the second accommodating groove 121. In this way, the first bearing 151 and the second bearing 152 can be hidden in the accommodating grooves, so that the bearings can be protected, and the bearings can be prevented from colliding with other parts inside the driving motor 100 to damage the bearings.

[0066] In a preferred embodiment, the first bearing 151 is located on a side of the winding group 142 close to the first housing 110, and the second bearing 152 is located on a side of the winding group 142 close to the second housing 120. The winding group 142 is provided with a receiving portion 1421 facing the first bearing 151 and the second bearing 152, and the first bearing 151 and the second bearing 152 are at least partially received in the receiving portion 1421. In other embodiments, the winding group is provided with a receiving portion 1421 facing the first bearing 151 or the second bearing 152, and the first bearing 151 or the second bearing 152 is at least partially received in the receiving portion 1421. In this way, the receiving space 160 of the driving motor 100 can be effectively utilized, and the receiving capacity of the receiving space 160 can be effectively increased without changing the height of the first housing 110 and the second housing 120 of the driving motor 100.

[0067] The motor shaft 130 penetrates the central region 111 of the first housing 110 and the second housing 120 along the height direction, which is the height direction of the fan lamp and the hoisting direction of the fan lamp. The first housing 110 further includes a fan blade mounting disc region 112 extending outward from the edge of the central region 111 and beyond the coverage area of the second housing 120, and the fan blades 400 are assembled on the fan blade mounting disc region 112. The plane where the highest point of the central region 111 is located and the plane where the highest point of the fan blade mounting disc region 112 is located have a first drop along the height direction. The first drop refers to the height of the plane where the highest point of the central region 111 is located protruding relative to the plane where the highest point of the fan blade mounting disc region 112 is located.

[0068] In addition, the central region 111 and the fan blade mounting disc region 112 have a first drop along the height direction, and the fan blade mounting disc region 112 is located on the same side of the central region 111 of the first housing 110. That is, the central region 111 protrudes from the fan blade mounting disc region 112 on the side away from the second housing 120, and at this time, the central region 111 and the second housing 120 can form a larger space, so that the internal space of the housing of the driving motor 100 can be increased without changing the height of the housing.

[0069] In an alternative embodiment, the fan blade mounting disc region 112 can have a connecting side 1121 connected to the central region 111 and an edge side 1122 away from the central region 111, and the fan blade 400 can be assembled to the edge side 1122. The edge side 1122 and the connecting side 1121 have a second height difference in the height direction. The second height difference refers to the height difference between the connecting side 1121 and the edge side 1122. In this scheme, the edge side 1122 is lower than the connecting side 1121, so that the fan blade mounting disc region 112 forms a recess structure, and at least part of the second shell 120 can be located in the recess structure, thereby being able to protect the second shell 120 and prevent the second shell 120 from colliding with other components of the fan lamp during rotation.

[0070] In an alternative embodiment, the central region 111 is recessed away from the second shell 120 in the height direction and on the side away from the second shell 120, forming a first receiving groove 115, and the second shell 120 is recessed away from the central region 111 in the height direction and on the side away from the first shell 110, forming a second receiving groove 121. In other embodiments, only the central region 111 of the first shell 110 can be recessed away from the second shell 120 in the height direction and on the side away from the second shell 120, forming a first receiving groove 115, or only the second shell 120 can be recessed away from the central region 111 in the height direction and on the side away from the first shell 110, forming a second receiving groove 121. In this way, the accommodation space 160 of the drive motor 100 can be further expanded, so that the height of the outer shell is small while the accommodation space 160 in the outer shell has a large internal space.

[0071] In an alternative embodiment, the second shell 120 can be located between the first shell 110 and the light source assembly 200, and the fan blade 400 is located on the side of the fan blade mounting disc region 112 away from the second shell 120. In this scheme, the second shell 120 can be located below the first shell 110, that is, the second shell 120 is the lower outer shell of the drive motor 100. Since the first shell 110 can cover the second shell 120, and the second shell 120 is located below the first shell 110, the connection between the second shell 120 and the first shell 110 is not easily exposed, so dust is not easily accumulated at the connection between the second shell 120 and the first shell 110, thereby improving the dustproof performance of the drive motor 100.

[0072] In addition, since the second shell 120 and the fan blade 400 are dispersed on both sides of the first shell 110, interference between the fan blade 400 and the second shell 120 is further avoided, and the assembly reliability of the fan lamp is improved.

[0073] In another alternative embodiment, the surface of the fan blade mounting disc area 112 can be provided with a plurality of reinforcing ribs 113, which can be spaced apart along the circumference of the fan blade mounting disc area 112. In this scheme, the reinforcing ribs 113 can reinforce the strength of the fan blade mounting disc area 112, thereby improving the strength of the fan blade mounting disc area 112.

[0074] In another alternative embodiment, the fan blade mounting disc area 112 can be provided with a fan blade fixing portion 114, and the fan blade 400 is rotatably connected to the fan blade fixing portion 114. Preferably, the fan blade 400 is a foldable fan blade, which is unfolded and extended beyond the fan blade mounting disc area 112 of the first housing 110 when the fan blade 400 is in operation. When the fan blade 400 is not in operation, it is retracted and does not extend beyond the fan blade mounting disc area 112 of the first housing 110. The fan blade fixing portion 114 is used to fix the fan blade 400, so that the fan blade 400 does not easily damage the fan blade mounting disc area 112 when it is replaced or repaired.

[0075] In order to facilitate the wiring of the fan lamp, in another alternative embodiment, the motor shaft 130 can be provided with a threading passage 136 along its axial direction, and the side wall of the portion of the motor shaft 130 inside the housing of the driving motor 100 is provided with a threading hole 137, which is in communication with the threading passage 136. In this scheme, the motor shaft 130 is a non-rotating part, and the threading hole 137 and the threading passage 136 are used to thread the wiring out, which avoids the wiring from being wound on the rotating parts of the driving motor 100, thereby improving the safety of the driving motor 100.

[0076] Please refer to Figures 12-22 shown, and in combination with Figure 3 shown, is a fan lamp according to a preferred embodiment of the present application. The fan lamp comprises a hanging assembly 500, a fan blade 400, a light source assembly 200, and a driving motor 100. The hanging assembly 500 is connected to a mounting base, and the driving motor 100 comprises a first housing 110, a second housing 120, and a motor shaft 130 penetrating through the first housing 110 and the second housing 120. One end of the motor shaft 130 is detachably connected to the hanging assembly 500, and the other end is fixedly connected to the light source assembly 200. The fan blade 400 is mounted on the first housing 110 and located on the side of the first housing 110 facing away from the light source assembly 200, and the second housing 120 is clamped between the first housing 110 and the light source assembly 200.

[0077] The hanging assembly 500 is used to be connected with a mounting base. The mounting base is used to hang the fan lamp. For example, the mounting base can be a ceiling of a house or the like. The hanging assembly 500 comprises a ceiling suction assembly and a hanger rod 510 assembly. The ceiling suction assembly is detachably connected with the hanger rod 510 assembly. The ceiling suction assembly comprises a ceiling suction box 550 and a support body 530 located inside the ceiling suction box 550. The support body 530 is connected with the mounting base. The support body 530 and the mounting base can be connected by bolts or the like. The support body 530 has a containing space for containing a hanger ball 520 of the hanger rod 510 assembly, a driver of the fan lamp and the like.

[0078] The containing space is provided with a fixing buckle 540 for fixing a traction rope. One end of the traction rope is connected with the fixing buckle 540, and the other end of the traction rope is connected with the light source assembly 200. At this time, the light source assembly 200 is pulled by the traction rope, so as to ensure the firmness of the installation of the light source assembly 200 and effectively reduce the risk of accidental falling of the light source assembly 200.

[0079] In the above embodiment, the containing space is provided with the fixing buckle 540, that is, the fixing buckle 540 is arranged on the support body 530. Compared with arranging the fixing buckle 540 on the mounting base, when the fan lamp is disassembled, the traction rope connected with the fixing buckle 540 needs to be first untied, and then the support body 530 is disassembled. At this time, the risk of falling of the light source assembly 200 in the process of disassembling the support body 530 is easily caused. In the present application, the fixing buckle 540 is arranged on the support body 530. When the fan lamp is disassembled, the traction rope does not need to be disassembled, so as to avoid the risk of falling of the light source assembly 200.

[0080] In addition, the fixing buckle 540 is arranged on the support body 530. Therefore, the fan lamp can be assembled as a whole and then installed on the mounting base, so as to reduce the assembly difficulty of the fan lamp.

[0081] In addition, the fixing buckle 540 is arranged in the containing space. Compared with arranging the fixing buckle 540 on the top of the support body 530, the support body 530 needs to reserve a space for containing the fixing buckle 540 between the support body 530 and the mounting base. Therefore, the size of the support body 530 in the height direction is large, and the appearance performance of the fan lamp is poor. In the present application, the fixing buckle 540 is arranged in the containing space. The support body 530 and the mounting base do not need to reserve a space for containing the fixing buckle 540. The size of the support body 530 in the height direction is reduced, so as to improve the appearance performance of the fan lamp.

[0082] In another alternative embodiment, as shown in FIG. 6, the traction rope is connected with the fixing buckle 540 through a connecting rod 560. Figure 15 and Figure 16As shown, the support body 530 can include a first connecting plate 531, a second connecting plate 532, a third connecting plate 533, a fourth connecting plate 534 and a fifth connecting plate 535 connected in sequence, the first connecting plate 531, the second connecting plate 532, the third connecting plate 533, the fourth connecting plate 534 and the fifth connecting plate 535 enclose a containing space, the first connecting plate 531 and the fifth connecting plate 535 can be oppositely arranged and located in the same plane. The second connecting plate 532 and the fourth connecting plate 534 can be located on opposite sides of the third connecting plate 533, the second connecting plate 532 can be located between the first connecting plate 531 and the third connecting plate 533, and the second connecting plate 532 can be connected to one side of the fifth connecting plate 535 close to the first connecting plate 531, the fourth connecting plate 534 can be located between the fifth connecting plate 535 and the third connecting plate 533, and the fourth connecting plate 534 can be connected to one side of the fifth connecting plate 535 close to the first connecting plate 531.

[0083] The fixing buckle 540 can be located on the second connecting plate 532 and / or the fourth connecting plate 534, and the first connecting plate 531 and the fifth connecting plate 535 can be connected to the mounting base respectively.

[0084] In this scheme, the first connecting plate 531 and the fifth connecting plate 535 are connected to the mounting base, so the first connecting plate 531 and the fifth connecting plate 535 are the top plates of the support body 530, the third connecting plate 533 is the bottom plate of the support body 530, and the second connecting plate 532 and the fourth connecting plate 534 are the side plates of the support body 530. Since the top plate of the support body 530 is used to connect with the mounting base, the bottom plate of the support body 530 is used to connect other components of the fan lamp, and the side plate is only used to connect the top plate and the bottom plate, so the side plate is not easy to interfere with other components of the fan lamp, so the fixing buckle 540 is arranged on the position of the side plate.

[0085] In order to improve the connection strength of the fixing buckle 540 and the support body 530, in another alternative embodiment, the fixing buckle 540 and the second connecting plate 532 or the fourth connecting plate 534 can be an integrated stamping structure. At this time, the fixing buckle 540 on the second connecting plate 532 or the fourth connecting plate 534 can be formed by stamping process, this scheme enhances the connection strength of the fixing buckle 540 and the support body 530, and avoids the connection fracture of the fixing buckle 540 and the support body 530.

[0086] In another alternative embodiment, the first connecting plate 531 can extend with a first protrusion 5311 towards one side of the fifth connecting plate 535, the fifth connecting plate 535 can extend with a second protrusion 5351 towards one side of the first connecting plate 531, and the first protrusion 5311 and the second protrusion 5351 can be in sliding connection. In this scheme, the connection of the first protrusion 5311 and the second protrusion 5351 can improve the strength of the support body 530. In addition, the first protrusion 5311 and the second protrusion 5351 can slide, at which time the distance between the first connecting plate 531 and the fifth connecting plate 535 can be adjusted, thereby facilitating the installation of the support body 530.

[0087] In another alternative embodiment, the third connecting plate 533 is provided with a mounting hole 5331, and the mounting hole 5331 can be in communication with the accommodating space. The hanging assembly 500 further comprises a hanging ball 520 and a hanging rod 510, and the hanging rod 510 has a second end 132 extending towards the outside, and the second end 132 is connected with the hanging ball 520. Part of the hanging ball 520 is located in the accommodating space, and the hanging ball 520 is arranged opposite to the mounting hole 5331. In this scheme, the hanging ball 520 can be clamped in the mounting hole 5331, and the hanging rod 510 can be connected with the part of the hanging ball 520 extending out of the accommodating space, so as to facilitate the hanging of the fan lamp.

[0088] In another alternative embodiment, the mounting hole 5331 penetrates towards the side adjacent to the first connecting plate 531. That is, the first connecting plate 531 is provided with an opening, the opening is in communication with the mounting hole 5331, when the hanging rod 510 and the support body 530 are disassembled, the hanging rod 510 is lifted, and the hanging rod 510 is moved out of the support body 530 from the penetrated side. When the hanging rod 510 and the support body 530 are installed, the hanging rod 510 is lifted, the hanging rod 510 is moved into the support body 530 from the penetrated side, and then the hanging rod 510 is dropped, and the hanging ball 520 is clamped in the mounting hole 5331.

[0089] In the above embodiment, during the disassembly of the hanging rod 510 assembly and the support body 530, the connection between the hanging ball 520 and the hanging rod 510 does not need to be disassembled, the hanging rod 510 and the hanging ball 520 can be directly moved out of the support body 530 at the same time, so as to facilitate the assembly and disassembly of the fan lamp.

[0090] The motor shaft 130 of the driving motor 100 comprises a first end 131 extending towards the hanging assembly 500 and a second end 132 extending towards the light source assembly 200, the hanging assembly 500 is fixedly connected with the first end 131, the second end 132 is fixedly connected with the light source assembly 200, and the fan blade 400 is installed on the first housing 110 of the driving motor 100.

[0091] Specifically, the boom 510 has a third end 511 extending downward, one of the third end 511 and the first end 131 is provided with the first threaded hole 1341, and the outer side wall of the other is provided with the first threaded surface 5111, and the boom 510 is threadedly connected with the motor shaft 130 through the first threaded hole 1341 and the first threaded surface 5111, as shown in Figure 20 and Figure 21 .

[0092] Compared with the fixing mode of welding, riveting or multiple bolts between the boom 510 and the motor shaft 130, the part of the boom 510 and the motor shaft 130 is a threaded structure, so that the boom 510 and the motor shaft 130 do not need to be fixed by external structures, thereby simplifying the installation steps of the fan lamp, reducing the complexity of the assembly of parts, and facilitating the assembly of the fan lamp.

[0093] In addition, when the driving motor 100 works, the motor shaft 130 and the boom 510 are subjected to a certain torsional force, and since the area of the matching surface of the first threaded hole 1341 and the first threaded surface 5111 is large, the torsional force between the motor shaft 130 and the boom 510 is evenly distributed on the matching surface of the first threaded hole 1341 and the first threaded surface 5111, so that the connection between the motor shaft 130 and the boom 510 is balanced, and the phenomenon of local excessive force and fracture is not easy to occur.

[0094] In addition, when the boom 510 and the motor shaft 130 are connected by welding, riveting or the like, the installer needs to first position the boom 510 and the motor shaft 130 before connecting, and the assembly process is complicated. The first threaded hole 1341 and the first threaded surface 5111 can complete positioning during screwing assembly, and positioning and connection are simultaneously performed, so that the assembly difficulty of the fan lamp is further simplified, and the assembly of the fan lamp is more convenient.

[0095] In the above embodiment, the first threaded hole 1341 can be provided on the end face of the motor shaft 130 or the boom 510, and the axis of the first threaded hole 1341 is parallel to or coincides with the axis of the motor shaft 130 and the axis of the boom 510.

[0096] Further, the motor shaft 130 can be provided with a first connecting hole 133 penetrating in the radial direction thereof, the boom 510 is provided with a second connecting hole 513 penetrating in the radial direction thereof, the first connecting hole 133 and the second connecting hole 513 can be oppositely arranged, and the first connecting piece 610 can penetrate the first connecting hole 133 and the second connecting hole 513, and the first connecting piece 610 penetrates the first threaded hole 1341 and the first threaded surface 5111.

[0097] In the scheme, when the boom 510 and the motor shaft 130 are threadedly connected, the first connecting piece 610 is inserted into the first connecting hole 133 and the second connecting hole 513, so as to effectively prevent the threads between the motor shaft 130 and the boom 510 from loosening, thereby ensuring the stability and firmness of the connection between the two.

[0098] Optionally, the first connecting piece 610 can be a bolt, and the first connecting hole 133 and the second connecting hole 513 can be threaded holes.

[0099] In another alternative embodiment, the motor shaft 130 can include a first shaft segment 134 and a second shaft segment 135 connected together, and the first shaft segment 134 can be provided with a first threaded hole 1341, and the diameter of the first shaft segment 134 can be greater than the diameter of the second shaft segment 135.

[0100] In the scheme, the first shaft segment 134 is provided with the first threaded hole 1341, so that the first shaft segment 134 is connected with the boom 510, and at this time, the part of the motor shaft 130 close to the boom 510 has a larger diameter, so that the first threaded hole 1341 is easy to process, and meanwhile, the strength of the motor shaft 130 is not affected.

[0101] In another alternative embodiment, the boom 510 further has a fourth end 512 extending upward, and the fourth end 512 is threadedly connected with the hanging ball 520. In the scheme, the boom 510 and the hanging ball 520 are threadedly connected, so that the boom 510 and the hanging ball 520 are easy to install and disassemble, and the fan lamp is easy to maintain.

[0102] Further, the hanging ball 520 can be provided with a second threaded hole 521, the outer side wall of the fourth end 512 can be provided with a second threaded surface 514, and the hanging ball 520 and the boom 510 can be threadedly connected through the second threaded hole 521 and the second threaded surface 514.

[0103] In the scheme, when the driving motor 100 works, the boom 510 and the hanging ball 520 are subjected to a certain torsional force, and since the area of the mating surface of the second threaded hole 521 and the second threaded surface 514 is large, the torsional force between the boom 510 and the hanging ball 520 is evenly distributed on the mating surface of the first threaded hole 1341 and the second threaded surface 514, so that the connection between the boom 510 and the hanging ball 520 is subjected to a relatively balanced force, and is not easy to break due to local excessive force.

[0104] Further, the hanging ball 520 is provided with a third connecting hole 522 communicated with the second threaded hole 521, an axis of the third connecting hole 522 intersects with an axis of the second threaded hole 521, the hanging rod 510 is provided with a fourth connecting hole 515 penetrating along a radial direction of the hanging rod 510, the third connecting hole 522 and the fourth connecting hole 515 can be oppositely arranged, and the second connecting member 620 can penetrate the third connecting hole 522 and the fourth connecting hole 515.

[0105] In this scheme, after the hanging rod 510 and the hanging ball 520 are threadedly connected, the second connecting member 620 penetrates the third connecting hole 522 and the fourth connecting hole 515, so as to effectively prevent the threads matched with each other between the hanging rod 510 and the hanging ball 520 from loosening, and further ensure the temperature resistance and firmness of the connection between the hanging rod 510 and the hanging ball 520.

[0106] Optionally, the second connecting member 620 can be a bolt, and the third connecting hole 522 and the fourth connecting hole 515 can be threaded holes.

[0107] The motor shaft 130 is provided with a second end 132 extending downward, the second end 132 is located at a side of the first shell 110 away from the fan blade 400, and the second end 132 is fixedly connected with the light source assembly 200. Optionally, the light source assembly 200 can be of various types, for example, an LED light source assembly 200 or a gas discharge light source assembly 200, and the embodiments of the present application are not limited.

[0108] In order to facilitate the installation of the light source assembly 200, in another optional embodiment, the fan lamp can further include a clamping assembly 300, the clamping assembly 300 can include a first clamping part 310 and a second clamping part 320, the first clamping part 310 and the second clamping part 320 can be sleeved on the first end 131 of the motor shaft 130, the first clamping part 310 can be located between the second clamping part 320 and the second shell 120, the first clamping part 310 can be fixedly connected with the motor shaft 130, for example, the first clamping part 310 and the motor shaft 130 can be connected in a welding manner. The second clamping part 320 is threadedly connected with the motor shaft 130, and part of the light source assembly 200 can be located between the first clamping part 310 and the second clamping part 320, specifically, the light source assembly 200 is at least partially located between the first clamping part 310 and the second clamping part 320.

[0109] In the specific operation process, when the light source assembly 200 is connected with the motor shaft 130, the second clamping portion 320 is screwed to gradually approach the first clamping portion 310, and finally the second clamping portion 320 and the first clamping portion 310 both touch the light source assembly 200. When the second clamping portion 320 cannot be screwed any more, the light source assembly 200 is assembled with the motor shaft 130. When the light source assembly 200 is disassembled with the motor shaft 130, the second clamping portion 320 is screwed to gradually move away from the first clamping portion 310, so that the second clamping portion 320 removes the force applied to the light source assembly 200, thereby achieving the disassembly of the motor shaft 130 and the light source assembly 200.

[0110] In this scheme, the second clamping portion 320 is screwed to achieve the installation and disassembly of the light source assembly 200 and the motor shaft 130, so that the motor shaft 130 and the light source assembly 200 are simple and convenient to assemble, thereby improving the assembly efficiency of the fan lamp.

[0111] Further, the second shell 120 of the driving motor 100 is located between the first shell 110 and the light source assembly 200, and the fan blade 400 is installed on the side of the first shell 110 away from the second shell 120. In this way, the second shell 120 can separate the light source assembly 200 from the first shell 110 by a distance, so that the fan blade 400 located on the first shell 110 is not easy to collide with the light source assembly 200 in the process of rotation, thereby improving the safety of the fan lamp.

[0112] The fan blade 400 of the fan lamp in the present application can adopt an open leaf type installation mode. Of course, the fan blade 400 can also adopt a hidden fan blade 400 structure.

[0113] In another alternative embodiment, the fan blade 400 can be unfolded or folded relative to the fan blade mounting disc area 112, that is, when the first shell 110 rotates, the fan blade 400 is driven by the centrifugal force to extend part of the fan blade 400 outside the fan blade mounting disc area 112 to drive air flow. When the first shell 110 stops rotating, the centrifugal force of the fan blade 400 decreases, and the fan blade 400 is retracted and hidden in the back of the fan lamp, thereby achieving the folding of the fan blade 400. That is, the fan blade 400 is a foldable fan blade, which is unfolded and extended beyond the fan blade mounting disc area 112 of the first shell 110 when the fan blade 400 is working. When the fan blade 400 is not working, it is folded and does not exceed the fan blade mounting disc area 112 of the first shell 110.

[0114] Optionally, the contraction of the fan blades 400 can be achieved by elastic stretchers, and the fan blades 400 can be elastically connected to the fan blade mounting disc area 112 through the elastic stretchers. When the first shell 110 rotates, the centrifugal force acting on the fan blades 400 is greater than the force of the elastic stretchers, so that the fan blades 400 are unfolded; when the first shell 110 stops rotating, the centrifugal force acting on the fan blades 400 is less than the force of the elastic stretchers, so that the fan blades 400 are contracted.

[0115] The fan blades 400 can include an inner edge 410 and an outer edge 420. In the unfolded state of the fan blades 400, the inner edge 410 gradually extends in a first direction from one end close to the central axis P of the central area 111 to the other end away from the central axis P, and the outer edge 420 gradually extends in the first direction from one end close to the central axis P to the other end away from the central axis P. An arc surface 430 is connected between the inner edge 410 and the outer edge 420, and the arc surface 430 extends from the inner edge 410 to the outer edge 420 in a direction opposite to the first direction. The first direction is a direction upward in the height direction.

[0116] In the contracted state of the fan blades 400, a gap M is provided between two adjacent fan blades 400.

[0117] In this scheme, the two ends of the inner edge 410 are not on the same horizontal plane. Specifically, in the unfolded state of the fan blades 400, the end of the inner edge 410 close to the central axis P of the central area 111 is lower than the end away from the central axis, so that the inner edge 410 gradually rises from the inner side to the outer side of the fan lamp. Similarly, the two ends of the outer edge 420 are not on the same horizontal plane. Specifically, in the unfolded state of the fan blades 400, the end of the outer edge 420 close to the central axis P of the central area 111 is lower than the end away from the central axis, so that the outer edge 420 gradually rises from the inner side to the outer side of the fan lamp. Based on this, the entire fan blade 400 is lower in the middle area of the fan lamp than in the edge area, that is, the inner end of the fan blade 400 is lower than the outer end. In this way, during the contraction of the fan blades 400, the outer end of the next fan blade 400 can pass above the inner end of the previous fan blade 400, and finally the fan blades 400 are contracted. When the fan blades 400 are contracted, a gap M is provided between two adjacent fan blades 400. Due to the existence of the gap M, the two adjacent fan blades 400 will not contact during the unfolding or contraction of the fan blades 400, thereby effectively alleviating the problem of damage to the fan blades 400 caused by abrasion and collision between the two adjacent fan blades 400.

[0118] And, the inner edge 410 and the outer edge 420 are connected through the arc surface 430, the arc surface 430 is curved from top to bottom from the inner edge 410 to the outer edge 420, so that the inner edge 410 is higher than the outer edge 420 as a whole. Because the inner edge 410 is in front and the outer edge 420 is in back during the operation of the fan lamp, the arc surface 430 can be used to blow air when the fan blade 400 moves, and the air is pushed through the arc surface 430 curved from top to bottom, so as to push more air flow, and thus achieve a better effect of stirring air, thereby improving the wind power of the fan lamp.

[0119] In summary, the driving motor 100 and the fan lamp having the same have simple structure, the fan blade 400 is directly assembled on the first shell 110 of the driving motor 100, so that the first shell 110 can be used as part of the shell of the driving motor 100, and the first shell 110 rotates with the second shell 120, thereby driving the rotation of the fan blade 400, so that the fan lamp does not need to separately set the shell of the driving motor 100 and the rotating disc of the fan blade 400, and the parts of the fan lamp are correspondingly reduced, the material is saved to a certain extent, the complexity of the assembly of the parts is reduced, and the assembly difficulty and the assembly error of the fan lamp are reduced.

[0120] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the present application.
