[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0035] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0036] This embodiment provides a fan, which may refer to a ceiling fan; of course, in other embodiments, the fan may also refer to a ceiling fan that integrates a light fixture.

[0037] The fan includes a fan body and a suspension structure 010. The fan body is mounted to a ceiling or other installation location via the suspension structure 010. Please refer to [reference needed]. Figure 1 The suspension structure 010 includes a hanger 100, a ball 200, and a rod assembly 300. The hanger 100 is used to mount the fan to a ceiling or other installation location. The ball 200 is mounted on the hanger 100. The rod assembly 300 is connected to the ball 200, and the fan body is connected to the rod 310. In this way, the fan body can be mounted to a ceiling or other installation location via the rod 310, the ball 200, and the hanger 100.

[0038] Furthermore, the hanger 100 is provided with a plug-in portion; the ball 200 includes a ball body 210 and a protrusion 220 connected to the ball body 210, and the protrusion 220 protrudes relative to the outer side wall of the ball body 210, both the ball body 210 and the protrusion 220 are plugged into the plug-in portion; the rod assembly 300 is assembled on the ball body 210, and the ball body 210 and the rod assembly 300 are locked by a first fastener 400, specifically, the first fastener 400... The first fastener 400 is connected to the ball body 210 and cooperates with the rod assembly 300 to prevent the rod assembly 300 from separating from the ball body 210. The first fastener 400 includes, but is not limited to, bolts and screws. The ball body 210 is provided with a wiring groove 211 for accommodating the grounding wire 600. The wiring groove 211 and the protrusion 220 at least partially overlap in the circumferential direction of the ball body 210. The first fastener 400 and the wiring groove 211 are distributed opposite to each other. This arrangement ensures that the first fastener 400, the wiring groove 211, and the protrusion 220 are roughly distributed along a single axis, making the overall structural design of the hanging ball 200 more reasonable and regular. This helps to improve the problem of the increased overall size of the hanging ball 200 caused by the messy distribution of the wiring groove 211, protrusion 220, and other structures on the hanging ball 200. In other words, it helps to reduce the overall volume occupied by the hanging ball 200 and achieve a compact structural design. At the same time, the position of the first fastener 400 mating with the hanging ball body 210 and the wiring groove 211 are relatively distributed, and the distance between them on the hanging ball body 210 is large. This will not have an adverse effect on the structural strength of the hanging ball body 210 itself. That is, the structural strength around the wiring groove 211 and the position of the first fastener 400 mating with the hanging ball body 210 will not be reduced because the wiring groove 211 and the position of the first fastener 400 mating with the hanging ball body 210 are too close.

[0039] Of course, in other embodiments, the first fastener 400 may be connected to the boom assembly 300 and cooperate with the ball body 210 to prevent the boom assembly 300 from separating from the ball body 210; or, in other embodiments, one of the ball body 210 and the protrusion 220 may be plugged into the insertion part.

[0040] The connection between the hanging ball body 210 and the protrusion 220 can be integrally formed. Of course, in other embodiments, the connection between the hanging ball body 210 and the protrusion 220 can also be by bonding, etc., which is not specifically limited here.

[0041] In this embodiment, please refer to Figure 2 and Figure 3 The ball bearing body 210 is provided with a plug-in cavity 212, into which the rod assembly 300 is plugged; the wiring groove 211 communicates with the plug-in cavity 212. This arrangement improves the ease of assembly of the rod assembly 300 and the ball bearing body 210, and ensures that the grounding wire 600 connected to the rod assembly 300 can be reliably housed in the wiring groove 211 communicating with the plug-in cavity 212, thereby improving the reliability of the connection between the grounding wire 600 and the rod assembly 300, and thus ensuring the safety of the fan in use.

[0042] Furthermore, the suspension structure 010 also includes a second fastener 500, which is connected to the boom assembly 300. A portion of the second fastener 500 is housed within the wiring groove 211. The second fastener 500 is used to connect the grounding wire 600 to the boom assembly 300. The second fastener 500 improves the reliability of the connection between the grounding wire 600 and the boom assembly 300. Furthermore, by housing both a portion of the second fastener 500 and the grounding wire 600 within the wiring groove 211, the problem of the second fastener 500 being accidentally loosened is mitigated, thereby ensuring that the wiring wire is reliably connected to the boom assembly 300 via the second fastener 500. The second fastener 500 includes, but is not limited to, bolts and screws.

[0043] Alternatively, please refer to Figure 4The wiring groove 211 has a first slot 2111 and a second slot 2112. The first slot 2111 communicates with the insertion cavity 212 and is distributed opposite to the rod assembly 300. The orientation of the first slot 2111 and the orientation of the second slot 2112 are distributed at an angle. The second slot 2112 is used to allow the grounding wire 600 to extend into the wiring groove 211. The insertion cavity 212 has a first opening and a second opening that are distributed opposite to each other. The rod assembly 300 is inserted into the insertion cavity 212 from the first opening, and one end of the rod assembly 300 extends out of the insertion cavity 212 from the second opening, while the other end is flush with the first opening or recessed into the insertion cavity 212 relative to the first opening. The orientation of the second slot of the wiring groove 211 is the same as the orientation of the first opening. This configuration allows the grounding wire 600 and the second fastener 500 connected to the boom assembly 300 to be accommodated in the wiring groove 211 from the second slot 2112 of the wiring groove 211. For example, after the grounding wire 600 is connected to the boom assembly 300 through the second fastener 500, when the boom assembly 300 is inserted into the boom body 210, the second fastener 500 and the grounding wire 600 can enter the wiring groove 211 together from the second slot 2112.

[0044] Alternatively, please refer to Figure 2 and Figure 3 The boom assembly 300 includes a boom 310 and a bushing 320 sleeved on the boom 310. The bushing 320 and the boom 310 are inserted together into the insertion cavity 212. A first fastener 400 is connected to the ball body 210 and cooperates with the bushing 320 to prevent the boom 310 and the bushing 320 from separating from the ball body 210. Specifically, the first fastener 400 has a connecting part and an abutting part connected to the connecting part. The connecting part is connected to the ball body 210, and the abutting part abuts against the bushing 320 to prevent the bushing 320 and the boom 310 from leaving the insertion cavity 212 from the first opening of the insertion cavity 212. The first fastener 400 and the wiring groove 211 are distributed opposite to each other on both sides of the insertion cavity 212.

[0045] Furthermore, the boom 310 is made of metal, such as stainless steel; the bushing 320 can be made of insulating material, such as rubber; to ensure that the metal boom 310 is reliably connected to the grounding wire 600, please refer to... Figure 3 The bushing 320 is provided with a clearance opening 321, which is connected to the wiring groove 211 and is used to avoid the second fastener 500 and the grounding wire 600, so as to ensure that the grounding wire 600 reliably contacts the metal rod 310, thereby improving the safety of the fan.

[0046] Optionally, the bushing 320 and the hanger rod 310 may be interference-fitted or bonded, etc., which are not specifically limited here; please refer to Figure 3The boom assembly 300 also includes a pin 330, which is simultaneously inserted into the bushing 320 and the boom 310. Both ends of the pin 330 protrude relative to the bushing 320, and both ends of the pin 330 overlap with the boom body 210, so as to prevent the boom 310 and the bushing 320 from sliding out of the second opening of the insertion cavity 212.

[0047] Furthermore, the ball bearing body 210 is provided with two slots 213, which are connected to the insertion cavity 212. The two ends of the pin 330 are respectively inserted into the two slots 213 in a one-to-one correspondence. In this way, the stability of the rod assembly 300 assembled on the ball bearing body 210 is ensured, as well as the ease of operation of the rod assembly 300 assembled on the ball bearing body 210. It is only necessary to insert one end of the rod 310 into the insertion cavity 212 from the first opening of the insertion cavity 212, and let the other end of the rod 310 protrude from the second opening of the insertion cavity 212. The bushing 320 and the other end of the rod 310 are inserted into the insertion cavity 212 together, and the pin 330 is inserted into the slot 213.

[0048] The structure of the 100mm hanger can be customized as needed; please refer to [reference needed]. Figure 5 In this embodiment, the hanger 100 includes a support plate 110 and a surrounding rib 120. The surrounding rib 120 is connected to the support plate 110 and protrudes relative to the surface of the support plate 110. The insertion part includes an opening 111 provided in the support plate 110 and an insertion interface 121 formed by the surrounding rib 120. The insertion interface 121 penetrates the support plate 110 and communicates with the opening 111. The protrusion 220 is inserted into the opening 111, and the hanging ball body 210 is inserted into the insertion interface 121. In this way, the surrounding rib 120 can be used to support the hanging ball body 210, thereby improving the stability of the hanging ball 200 assembled in the hanger 100.

[0049] Optionally, the hanger 100 also includes a lifting component 130, which is connected to the support plate 110 and used for connection to an installation location such as a ceiling. The specific structure of the lifting component 130 is similar to related technologies and will not be described in detail here.

[0050] The connection methods of the support plate 110 and the surrounding reinforcement 120, as well as the connection methods of the support plate 110 and the lifting component 130, include, but are not limited to, integral molding and welding.

[0051] In this embodiment, please refer to Figure 1Along the axial direction of the hanger assembly 300, the width of the protrusion 220 gradually increases from the end near the insertion part to the end away from the insertion part (a structure that is wider at the top and narrower at the bottom). This arrangement ensures that the protrusion 220 can be reliably inserted into the opening 111 of the support plate 110, and forms an interference fit between the protrusion 220 and the opening 111 of the support plate 110. This helps to reduce the gap between the two ends of the circumferential rib 120 that communicate with the opening 111 and the hanging ball body 210, thereby increasing the friction between the hanging ball body 210 and the rib 120. By increasing the friction, the stability of the fan body during operation is improved by assembling the hanger 310 and the hanging ball 200 onto the hanger 100, thus reducing the vibration phenomenon that occurs when the fan body is running.

[0052] It should be noted that when assembling the suspension structure 010 with the ceiling and other installation positions, various installation positions may have a certain tilt angle, that is, the ceiling and other installation positions may not be horizontal. Therefore, during installation, it is necessary to rotate the hanging ball 200 relative to the hanger 100 around a set axis to adjust the position of the hanging rod 310 connected to the hanging ball 200 relative to the horizontal plane. That is, by adjusting the relative position of the hanging ball 200 and the hanger 100, the hanging rod 310 is set vertically, wherein the set axis extends in the horizontal direction. The protrusion 220 is set as a structure that is wider at the top and narrower at the bottom. When the hanging ball 200 is rotated relative to the hanger 100 along the set axis, it can prevent the hanging ball body 210 from rotating too much and causing the protrusion 220 to disengage from the opening 111 of the support plate 110, and prevent the hanging ball body 210 from disengaging from the insertion interface 121, thereby ensuring the stability of the hanging ball body 210 and the protrusion 220 assembled with the hanger 100.

[0053] It should also be noted that designing the convex hull 220 as a structure that is wider at the top and narrower at the bottom, compared to designing the convex hull 220 as having a uniform width, can reduce the requirements for manufacturing precision, increase the production error tolerance, and help improve the product qualification rate.

[0054] In this embodiment, the suspended ball body 210 is projected onto a set plane in an elliptical shape, and has a vertically distributed major axis and minor axis; the set plane is angled to the axis of the suspension rod assembly 300. This arrangement allows for a more rational distribution of external forces on the suspended ball 200. Specifically, the elliptical projection of the suspended ball body 210 distributes the force on both sides of the axial direction of the shorter axis, which has greater structural strength. This improves the structural strength of the suspended ball 200 and allows for a larger contact area between the short axis and the surrounding rib 120, enhancing the stability of the fan body assembled on the hanger 100 via the suspension rod 310 and the suspended ball 200, and improving fan safety, thus mitigating the problem of the fan body falling due to damage to the suspended ball 200. Furthermore, the elliptical shape of the suspended ball body 210 facilitates rotation around its major axis, ensuring the flexibility of adjusting the relative position of the suspended ball 200 relative to the hanger 100.

[0055] It should be noted that in this embodiment, the plane is set to be perpendicular to the axis of the boom assembly 300; of course, in other embodiments, the angle between the plane and the axis of the boom assembly 300 can also be 89°, 88°, etc., and is not specifically limited here. The axis of the boom assembly 300 is the same as the axis of the boom 310.

[0056] Alternatively, please refer to Figure 3 The ball body 210 includes a first enclosure 214 and a second enclosure 215 connected to each other, and the second enclosure 215 is distributed inside the first enclosure 214. The second enclosure 215 and the first enclosure 214 are also connected by a reinforcing rib 216. The second enclosure 215 is provided with a wiring groove 211, a plug cavity 212 and a slot 213. The first enclosure 214 is elliptical when projected onto a set plane. The side of the first enclosure 214 away from the second enclosure 215 cooperates with the enclosure rib 120.

[0057] Furthermore, at least a portion of the side of the first enclosure 214 facing away from the second enclosure 215 is an arc-shaped convex surface, and the rib 120 is adapted to the side of the first enclosure 214 facing away from the second enclosure 215 to increase the contact area between the rib 120 and the first enclosure 214 and improve the stability of the hanging ball 200 assembled on the hanger 100.

[0058] It should be noted that by setting the hanging ball body 210 to an elliptical shape, that is, by setting the appearance of the first enclosure plate 214 to an elliptical shape, the curvature of the different mating surfaces between the first enclosure plate 214 and the enclosure rib 120 can be used to increase the vertical component of the hanging ball body 210, thereby increasing the friction between the hanging ball body 210 and the hanger 100, and improving the stability of the fan body light operation.

[0059] Optionally, the first enclosure 214 and the second enclosure 215 are connected by a plurality of reinforcing ribs 216, one of which is distributed opposite to the wiring groove 211 along the axial direction of the long axis of the first enclosure 214, and the first fastener 400 is connected to the reinforcing rib 216; the protrusion 220 is connected to the first enclosure 214 in an integral form and is located at the end of the axial direction of the long axis of the first enclosure rib 120, the protrusion 220 and the wiring groove 211 are distributed at one end of the axial direction of the long axis of the ball body 210, and the first fastener 400 is distributed at the other end of the axial direction of the long axis of the ball body 210.

[0060] Of course, in other embodiments, the projected ball body 210 onto a set plane is circular.

[0061] The assembly process of the suspension structure 010 in this embodiment includes: inserting the pin 330 into the rod assembly 300, inserting the rod assembly 300 into the insertion cavity 212, and embedding the grounding wire 600 and the second fastener 500 connected to the rod assembly 300 into the wiring groove 211; connecting the first fastener 400 to the ball body 210, and making the first fastener 400 abut against the rod assembly 300; and inserting the ball 200 into the insertion part of the hanger 100.

[0062] In summary, the suspension structure 010 of this utility model can be used for fans (i.e. ceiling fans), and the structural design of the hanging ball 200 of the suspension structure 010 is more reasonable, which helps to reduce the overall volume occupied by the hanging ball 200, achieve a compact structural design, and does not affect the structural strength of the hanging ball 200 itself.

[0063] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
