Ceiling fan rotating shaft and ceiling fan having the rotating shaft

Abstract

This invention relates to a ceiling fan rotating shaft and a ceiling fan having the rotating shaft. The ceiling fan comprises at least one rotating shaft, which includes a semi-circular base and a hemispherical guide portion protruding from the base. The guide portion has a guide surface. The lower sealing ring of the ceiling fan has at least one protrusion, through which the guide portion passes, and the guide surface abuts against the protrusion. By machining the base of the rotating shaft into a semi-circular plate and the guide portion into a hemispherical shape, the guide surface and protrusion cooperate to achieve rotation when the rotating shaft rotates. Compared to existing rotating shaft components constructed with a complete sphere combined with a plate structure, this invention reduces the overall volume, achieving weight reduction, lower power consumption, lower processing costs, and easier installation.

Description

Technical Field

[0001] This invention relates to a ceiling fan and a rotating shaft, and more particularly to a ceiling fan with a rotating function and a ceiling fan rotating shaft. Background Technology

[0002] like Figure 7 As shown, in the prior art, ceiling fans, especially rotating ceiling fans, have a rotating shaft 90 and a sealing ring 91 in their main rotating structure. The rotating shaft 90 includes a plate 901 and a ball 902. The ball 902 protrudes from one side of the plate 901 and is a solid metal structure integrally formed. The two opposite sides of the ball 902 are respectively processed to form a long groove 903, and a through hole (not shown) passes through the ball 902 and the plate 901. The rotating shaft 90 is fixed to a drive motor (not shown) by the plate 901. The drive rod of the drive motor passes through the through hole and connects to the fan blades of the ceiling fan. The inner side of the sealing ring 91 has two protrusions 911, which are arranged opposite each other. The ball 902 of the rotating shaft 90 passes through the sealing ring 91 and the two protrusions 911 are located in the long groove 903, thereby enabling the rotating shaft 90 to rotate relative to the sealing ring 91, thereby driving the fan blades to rotate synchronously.

[0003] However, the aforementioned rotating shaft 90 is made entirely of metal, which has a certain weight and volume, and the long groove is difficult to process. When the rotating shaft 90 is installed in the ceiling fan, it will not only increase the volume of the overall structure, but also increase the weight. This will increase the load on the rotating motor, resulting in increased power consumption and reduced service life. It will also increase the handling cost during transportation. Therefore, the existing ceiling fan has the aforementioned problems and shortcomings in its overall structure, which need to be improved. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a ceiling fan that achieves the purpose of lightweighting and ease of manufacturing by changing the structure of the rotating shaft of the existing ceiling fan.

[0005] To achieve the above-mentioned objectives, the present invention further employs a technical means of designing a ceiling fan, which includes:

[0006] A fixed base includes a lifting member and a synchronous motor. One end of the lifting member is recessed to form an accommodating space, and the synchronous motor is disposed on the lifting member and located within the accommodating space.

[0007] A drive device, one end of which is connected to the synchronous motor and the other end of which is connected to a drive rod;

[0008] At least one ceiling fan rotating shaft, the ceiling fan rotating shaft having a base and a guide portion formed at opposite ends, the base being a semi-circular plate having multiple fixing holes, an inner surface and a recess, each fixing hole penetrating the base, the inner surface being located on one side of the base, the recess being recessed within the inner surface, the guide portion being a hemispherical body formed on one side of the base, the guide portion having a guide surface and a through groove, the guide surface being parallel to the inner surface, the through groove being recessed within the guide surface and communicating with the recess, the ceiling fan rotating shaft being secured to the drive device by multiple fasteners passing through each fixing hole, the drive rod passing through the through groove;

[0009] The lower cover has a recessed groove at one end to form a mounting groove. A shaft hole passes through the bottom of the mounting groove, and the lower cover is fixed to the fixing seat.

[0010] The lower sealing ring includes a ring frame and at least one protrusion. The protrusion protrudes from the inner side of the ring frame. The lower sealing ring is fixed in the mounting groove of the lower cover. The guide part of the ceiling fan rotating shaft passes through the lower sealing ring and the shaft hole, and the guide surface abuts against the protrusion.

[0011] A blade assembly is fixed to the drive rod.

[0012] Furthermore, in the aforementioned ceiling fan, there are two at least one fan rotating shafts and two at least one protrusion. The two fan rotating shafts are located on opposite sides of the two protrusions, and the guide surfaces of the two fan rotating shafts are arranged opposite each other.

[0013] Furthermore, the ceiling fan further includes a retaining ring, which is a C-shaped ring, and the retaining ring covers the lower sealing ring and is fixed to the lower cover.

[0014] The advantage of this invention is that by processing the base of the ceiling fan's rotating shaft into a semi-circular plate and the guide part into a hemispherical shape, the guide surface and the protrusion can cooperate to achieve the rotation action when the ceiling fan's rotating shaft rotates. Compared with the existing technology of rotating shaft components composed of a complete sphere combined with a plate structure, this invention has the advantages of reduced overall volume, lighter weight, reduced power consumption, lower processing costs, and easier installation.

[0022] The following, in conjunction with the accompanying drawings and preferred embodiments of the present invention, further illustrates the technical means employed by the present invention to achieve its intended purpose.

[0023] Please see Figure 1 and Figure 2 As shown, the ceiling fan of the present invention includes at least one ceiling fan rotating shaft 10, a fixed base 20, a drive device 30, a lower cover 40, a lower sealing ring 50, a fixing ring 60, and a blade assembly 70.

[0024] Please see Figures 2 to 5 As shown, the ceiling fan rotating shaft 10 includes a base 11 and a guide part 12. The guide part 12 and the base 11 are integrally formed by stamping. The base 11 is a semi-circular sheet with multiple fixing holes 111, an inner side surface 112 and a recess 113. Each fixing hole 111 passes through the base 11 at intervals. The inner side surface 112 is located on one side of the base 11, specifically the diameter side of the semi-circular base 11. The recess 113 is recessed into the inner side surface 112. In this embodiment, the recess 113 is an arc-shaped opening, but it is not limited to this. The shape of the recess 113 can be changed according to the user's needs.

[0025] The guide part 12 is hemispherical and is formed on one side of the base 11 and adjacent to the inner side 112. The guide part 12 has a guide surface 121 and a through groove 122. The guide surface 121 is parallel to the inner side 112. The through groove 122 is recessed in the guide surface 121 and communicates with the notch 113. In this embodiment, the through groove 122 is an arc-shaped groove, but it is not limited thereto. The shape of the through groove 122 can be changed according to the user's needs.

[0026] Please see Figures 1 to 3 As shown, the mounting base 20 includes a hanging member 21, a synchronous motor 22 and a connecting rod 23. One end of the hanging member 21 is recessed to form an accommodating space. The synchronous motor 22 is disposed on the hanging member 21 and located in the accommodating space. One end of the connecting rod 23 is connected to the synchronous motor 22. In this embodiment, the synchronous motor 22 is a motor, but it is not limited thereto. The other end of the hanging member 21 is used to fix it to the ceiling.

[0027] One end of the drive device 30 is connected to the other end of the connecting rod 23, and the other end of the drive device 30 is connected to a drive rod 31. In this embodiment, the drive device 30 is a motor, but it is not limited thereto. The drive device 30 can be tilted at an angle and rotates around the position where the connecting rod 23 is connected to the synchronous motor 22. The ceiling fan rotating shaft 10 is secured to the drive device 30 by multiple fasteners passing through each fixing hole 111. The drive rod 31 passes through the through slot 122. In this embodiment, there are two ceiling fan rotating shafts 10, which are arranged opposite each other at intervals with each guide surface 121, but it is not limited thereto, and there may also be only one.

[0028] One end of the lower cover 40 is recessed to form a mounting groove, and a shaft hole 41 passes through the bottom of the mounting groove. The lower cover 40 is fixed to the fixing seat 20 and covers the drive device 30 and the ceiling fan rotating shaft 10 therein.

[0029] The lower sealing ring 50 includes a ring frame 51 and two protrusions 52. The two protrusions 52 are respectively protruding on the inner side of the ring frame 51. The lower sealing ring 50 is fixed in the mounting groove of the lower cover 40. The guide part 12 of each ceiling fan rotating shaft 10 passes through the lower sealing ring 50 and the shaft hole 41. Each guide surface 121 abuts against the two protrusions 52, but this is not a limitation. The number of protrusions 52 may also be only one.

[0030] The fixing ring 60 is a C-shaped ring, and the fixing ring 60 covers the lower sealing ring 50 and is fixed to the lower cover 40.

[0031] The blade assembly 70 is fixed to the drive rod 31. The blade assembly 70 is a blade-related component of the existing ceiling fan, and its detailed structure will not be described in detail.

[0032] When using this invention, please refer to [link / reference]. Figure 2 , Figure 5 and Figure 6 As shown, the user fixes the ceiling fan to the ceiling with the hanging bracket 21. When the ceiling fan is started, the synchronous motor 22 drives the connecting rod 23 to rotate, so that the drive device 30 rotates around the point where the connecting rod 23 is connected to the synchronous motor 22. During the rotation of the drive device 30, each ceiling fan rotating shaft 10 rotates synchronously with each guide surface 121 abutting against the two protrusions 52, thereby stabilizing the blade assembly 70 and the drive device 30 to rotate. By processing the base 11 of the ceiling fan rotating shaft 10 into a semi-circular plate and the guide part 12 into a hemispherical shape, when the ceiling fan rotating shaft 10 rotates, the guide surface 121 and the two protrusions 52 can cooperate to achieve the rotation action. Compared with the existing technology of rotating shaft components composed of a complete sphere combined with a plate structure, the overall volume is reduced, which can achieve the effects of weight reduction, power consumption reduction, processing cost reduction and easy installation.
