The first rotating shaft 11 has a first mounting end 111 and a second mounting end 112; the first fan wheel 12 is fixedly disposed at the first mounting end 111 of the first rotating shaft 11, and is used to mount the fan blades 60, and the outer periphery of the first fan wheel 12 also has a first belt groove 121; the transmission wheel 13 is fixedly disposed at the second mounting end 112 of the first rotating shaft 11, and is used to connect with the driving device 70.

[0048] The transmission wheel 13 of the first ceiling fan assembly 10 is fixedly arranged at the second mounting end 112 of the first rotating shaft 11, and is used to be connected with the driving device 70. The driving device 70 drives the transmission wheel 13 to rotate, so that the first rotating shaft 11 can drive the first fan wheel 12 to rotate. The driving device 70 can be a driving motor, and the transmission connection between the driving device 70 and the transmission wheel 13 can be connected by a gear transmission connection or a transmission belt 80 transmission connection, but it is not limited to this. In the embodiment of the present application, the connection between the driving device 70 and the transmission wheel 13 is described as a transmission belt 80 connection.

The pulley is sleeved on the second mounting end 112 of the first rotating shaft 11, one side of the pulley is against the shaft ring 113, and the other side is flush with the end surface of the second mounting end 112 of the first rotating shaft 11, and the pulley and the first rotating shaft 11 can be connected by a key, but it is not limited to this. Of course, a fixing hole can also be set on the end surface of the second mounting end 112, an end cover can be set on the end surface of the second mounting end 112, and then fasteners can be used to cooperate with the fixing hole to further ensure the stability of the fixed connection between the transmission wheel 13 and the second mounting end 112 of the first rotating shaft 11.

[0049] The first fan wheel 12 is fixedly disposed on the first mounting end 111 of the first rotating shaft 11, and is used to mount the fan blades 60, and the outer periphery of the first fan wheel 12 has a first belt groove 121. By providing the first belt groove 121 on the outer periphery of the first fan wheel 12, the first fan wheel 12 can be used as a driving wheel to drive other ceiling fans to rotate through the belt drive belt 80. The fan blades 60 of the first ceiling fan assembly 10 are mounted on the first fan wheel 12, and threaded holes are provided on one end surface of the first fan wheel 12 for mounting the fan blades 60, so that the size and distribution of the threaded holes can be consistent with the installation requirements of the traditional ceiling fan blades 60, so that the original ceiling fan blades 60 can be used to save resources.

[0050] It should be noted that the embodiment of the present application does not limit the specific number of the first belt grooves 121 on the periphery of the first fan wheel 12 . For example, the first belt grooves 121 can be arranged in one circle, two circles or more circles on the periphery of the first fan wheel 12 .

[0051] See also Figure 2 In some embodiments, the ceiling fan assembly further includes a second ceiling fan assembly 20.

The second fan wheel 22 is fixedly disposed at one end of the second rotating shaft 21 and is used to mount the fan blades 60. The outer periphery of the second fan wheel 22 has at least two circles of second belt grooves 221.

[0052] The second fan wheel 22 is provided with threaded holes on one side section for mounting the blades 60. The size and distribution of the threaded holes can also be made consistent with the installation requirements of the blades 60 of the conventional ceiling fan, so that the blades 60 of the original ceiling fan can be used, that is, the size and distribution of the threaded holes for mounting the blades 60 on the first fan wheel 12 and the second fan wheel 22 are the same. By providing at least two circles of second belt grooves 221 on the periphery of the second fan wheel 22, after the second ceiling fan assembly 20 is connected to the first ceiling fan assembly 10 through the transmission belt 80, the second ceiling fan assembly 20 can also be connected to another second ceiling fan assembly 20 through the transmission belt 80, and every two adjacent second ceiling fan assemblies 20 in the ceiling fan assembly can be connected through the transmission belt 80.

[0053] In order to unify the parts in the first ceiling fan assembly 10 and the second ceiling fan assembly 20 as much as possible and reduce the types of molds in the production of ceiling fan assemblies, the structure of the first fan wheel 12 can be made the same as the structure of the second fan wheel 22. For example, in some embodiments, the first fan wheel 12 has two circles of first belt grooves 121, and the second fan wheel 22 has two circles of second belt grooves 221.

[0054] like Figure 1 and Figure 2As shown, in some embodiments, the first fan wheel 12 and the second fan wheel 22 both have a mounting surface 31 and a fixing sleeve 32. The mounting surface 31 is used to mount the fan blades 60, and the fixing sleeve 32 has a mounting hole 33.

After the first fan wheel 12 is sleeved on the outer periphery of the first mounting end 111 of the first rotating shaft 11, since the fixing sleeve 32 of the first fan wheel 12 is formed on the side of the first fan wheel 12 facing away from the mounting surface 31, after the first fan wheel 12 is sleeved on the first rotating shaft 11, the fixing sleeve 32 is located on the side of the first fan wheel 12 facing the second mounting end 112. The first through hole 114 of the first rotating shaft 11 is matched with the mounting hole 33 of the fixing sleeve 32, that is, the first through hole 114 corresponds to the mounting hole 33, and then the fastener passes through the mounting hole 33 and the first through hole 114, so that the first fan wheel 12 is fixed to the first rotating shaft 11.

[0057] In the second fan wheel 22 , the fixing sleeve 32 is formed on the side of the second fan wheel 22 facing away from the mounting surface 31 and is sleeved on the outer periphery of the second rotating shaft 21 .

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, to ensure the stability of the fixed connection between the first fan wheel 12 and the first rotating shaft 11 and between the second fan wheel 22 and the second rotating shaft 21 , the first fan wheel 12 and the second fan wheel 22 both have nested through holes 34 .

[0060] In the first ceiling fan assembly 10, the first rotating shaft 11 is embedded in the nesting through hole 34 of the first fan wheel 12. The first ceiling fan assembly 10 also includes a first end cover 15, which is located on the mounting surface 31 of the first fan wheel 12 and is fixedly connected to the end surface of the first mounting end 111 of the first rotating shaft 11.

The second ceiling fan assembly 20 also includes a second end cover 24, which is located on the mounting surface 31 of the second fan wheel 22 and fixedly connected to the end surface of the second rotating shaft 21.

[0063] The nesting hole of the second fan wheel 22 is set through the second fan wheel 22, and the second rotating shaft 21 is embedded in the nesting through hole 34 of the second fan wheel 22, that is, the second fan wheel 22 is sleeved on the outer periphery of the second rotating shaft 21. After the second rotating shaft 21 is embedded in the nesting through hole 34 of the second fan wheel 22, the end surface of the second rotating shaft 21 and the second fan wheel 22 are flush with the mounting surface 31 of the second fan wheel 22. The end surface of the second rotating shaft 21 and the second fan wheel 22 can also be provided with a fixing hole, and the second end cover 24 is fixedly connected to the end surface of the second rotating shaft 21 by making the fasteners match the fixing holes.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments, in order to achieve fixed installation of the first ceiling fan assembly 10 in the ceiling fan assembly, the first ceiling fan assembly 10 also includes a first mounting portion 14, and the first rotating shaft 11 is rotatably matched with the first mounting portion 14. In the axial direction along the first rotating shaft 11, the first mounting portion 14 is located between the first fan wheel 12 and the transmission wheel 13.

[0065] In the first ceiling fan assembly 10, the second mounting end 112 of the first rotating shaft 11 is formed with a shaft ring 113, and one side of the transmission wheel 13 is abutted against the shaft ring 113, so that the first mounting portion 14 can be abutted against the side of the shaft ring 113 facing away from the transmission wheel 13, and then a first spacer ring 16 is arranged between the first mounting portion 14 and the first fan wheel 12.

[0066] Correspondingly, the second ceiling fan assembly 20 further includes a second mounting portion 23, and the second shaft 21 is rotatably matched with the second mounting portion 23. The second mounting portion 23 can be disposed at an end of the second shaft 21 away from the second fan wheel 22, and a second spacing ring 25 can also be disposed between the second mounting portion 23 and the second fan wheel 22.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the structures of the first mounting portion 14 and the second mounting portion 23 can be made the same, and the first mounting portion 14 and the second mounting portion 23 can both include a mounting seat 41 and a bearing group 42. The bearing group 42 includes an upper bearing 421 and a lower bearing 422.

[0068] Taking the installation position of the first ceiling fan assembly 10 and the second ceiling fan assembly 20 in normal use as an example, it can be understood that the first rotating shaft 11 and the second rotating shaft 21 are placed vertically, the upper bearing 421 in the bearing group 42 is arranged above the mounting seat 41, and the lower bearing 422 is arranged below the mounting seat 41. It can be understood that the mounting seat 41 is a bearing seat, for example, the mounting seat 41 can be a double-bearing vertical bearing seat.

[0069] In some embodiments, the upper bearing 421 may be an angular contact ball bearing, and the lower bearing 422 may be a deep groove ball bearing. Since the angular contact ball bearing can withstand a large axial force, it is beneficial to support the entire fan assembly. The deep groove ball bearing has a certain degree of self-alignment.

The first ceiling fan assembly 10 and the second ceiling fan assembly 20, as well as the two adjacent second ceiling fan assemblies 20, are connected by a transmission belt 80.

[0071] It can be understood that the ceiling fan device can also include a driving device 70, which is connected to the transmission wheel 13 of the first ceiling fan assembly 10, so that the first ceiling fan assembly 10 and several second ceiling fan assemblies 20 in the ceiling fan device can be driven to work by one driving device 70.

[0072] Please also read Figure 4In some embodiments, a plurality of waist-shaped holes 51 are provided on the mounting frame 50, and the first ceiling fan assembly 10 and the plurality of second ceiling fan assemblies 20 are provided on the mounting frame 50 by fasteners passing through the waist-shaped holes 51. It can be understood that fasteners are provided on the first mounting portion 14 and the second mounting portion 23, and the first ceiling fan assembly 10 is installed on the mounting frame 50 by passing the fasteners on the first mounting portion 14 through the waist-shaped holes 51, and the second ceiling fan assembly 20 is installed on the mounting frame 50 by passing the fasteners on the second mounting portion 23 through the waist-shaped holes 51.

[0073] Correspondingly, a plurality of tensioning parts 52 are also provided on the mounting frame 50. The tensioning parts 52 are used to push the first ceiling fan assembly 10 and the second ceiling fan assembly 20 to move along their corresponding waist-shaped holes 51 to tension the transmission belt 80.

[0074] It can be understood that at least one tensioning portion 52 is correspondingly provided for each second ceiling fan assembly 20 on the mounting frame 50, and of course, a tensioning portion 52 can also be correspondingly provided for the first ceiling fan assembly 10. The tensioning portion 52 can include an adjustment base 521 and an adjustment screw 522, and the adjustment base 521 is provided with a threaded hole that cooperates with the adjustment screw 522. Taking the second ceiling fan assembly 20 as an example for explanation, the tensioning portion 52 is located on one side of the second mounting portion 23 in the second ceiling fan assembly 20.
