Description

Technical Field

[0001] This invention relates to a fan light, belonging to the field of fan lights. Background Technology

[0002] Currently, the fan blades in fan lights are mainly mounted on the fan light body via bearings. The bearings require multiple structures, which increases the cost. Additionally, dust can easily enter the bearings through the gaps in the fan blades, leading to excessive friction between the fan blades and the fan light body, which can generate friction noise. Furthermore, additional lubricating oil is required.

[0003] In view of this, it is indeed necessary to propose a fan light to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a fan light that can reduce the friction of the fan blades.

[0005] To achieve the above objectives, the present invention provides a fan light, including a housing and fan blades connected to the housing. The housing is driven by a motor and drives the fan blades to rotate synchronously. The housing is provided with a mounting base, and the mounting base has a receiving cavity facing away from the opening of the fan blades. The receiving cavity houses a bearing. The fan blades are provided with a fixing part, and the fixing part is pivotally connected to the mounting base through the bearing. The fixing part is also provided with a torsion spring, and the two ends of the torsion spring are respectively fixed to the housing and the fan blades.

[0006] As a further improvement of the present invention, the fixing part includes a first annular wall and a second annular wall extending toward the housing, the torsion spring is received between the first annular wall and the second annular wall, the first annular wall is arranged around the outside of the second annular wall, a groove is formed on the second annular wall, the first end of the torsion spring is engaged in the groove, and a reinforcing rib is also provided on the outside of the first annular wall, the reinforcing rib being used to connect the fan blade and the fixing part.

[0007] As a further improvement of the present invention, the fixing part is installed from above the mounting part, the mounting base is provided with a sliding groove, and an extension part extending away from the fixing part is provided outside the sliding groove. A through hole is formed in the extension part, and the second end of the torsion spring passes through the sliding groove and is engaged in the through hole.

[0008] As a further improvement of the present invention, the outer ring of the bearing is fixedly connected to the mounting base, and a fastener is provided in the inner ring of the bearing. The fastener passes through the fixing part to fix the fixing part to the inner ring of the bearing, so that the fan blade can rotate freely around the mounting base.

[0009] As a further improvement of the present invention, the top of the receiving cavity has a mounting hole through which the fastener passes, and the opening of the receiving cavity is also provided with a nut for fastening with the fastener, and a washer is also provided between the nut and the bearing.

[0010] As a further improvement of the present invention, the mounting base is also provided with a first limiting part, which extends vertically upward, and the outer side of the first annular wall is provided with an outwardly protruding part. When the fan blade rotates relative to the housing, the protruding part abuts against the first limiting part to limit the maximum rotation angle of the fan blade.

[0011] As a further improvement of the present invention, the mounting base is further provided with a second limiting part, which extends vertically upward. When the housing is in a non-rotating state, the torsion spring is configured to generate a force that causes the protrusion to abut against the second limiting part.

[0012] As a further improvement of the present invention, the fan blades are provided in three parts, and when the protrusion abuts against the second limiting part, the orthographic projection of the fan blades on the horizontal plane completely overlaps with the orthographic projection of the housing on the horizontal plane.

[0013] As a further improvement of the present invention, the motor is disposed at the center of the housing, the motor includes a motor shaft, and the motor is capable of driving the housing to rotate around the motor shaft.

[0014] As a further improvement of the present invention, the fan light also includes a light source module for illumination.

[0015] The beneficial effects of this invention are: by placing the bearing at the bottom of the mounting base, dust can be prevented from entering the bearing, thereby reducing the friction between the fan blade and the housing, simplifying the structure and reducing costs. In addition, no additional lubricating oil is required, which improves assembly efficiency and reliability. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0026] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] like Figures 1 to 8 As shown, this invention discloses a fan light 100, which is a combination of a fan and a light fixture. The fan light 100 includes a main body and a mounting bracket, with the main body disposed below the mounting bracket, which is fixed to a mounting surface such as a ceiling. For clarity, the following description will use the fan light 100 as an example for detailed explanation.

[0028] Combination Figure 2 and Figure 3As shown, the main body of the fan light 100 includes a housing 10, a motor 20, and fan blades 30. The housing 10 is disc-shaped, and the motor 20 includes a casing 21, a motor shaft 22, a rotor, and a stator. The casing 21 and the motor 20 are located at the center of the housing 10, and the casing 21 is integrally formed with the housing 10. The motor shaft 22 extends axially along the central axis of the housing 10 and is fixedly connected to the mounting bracket. The rotor is fixedly connected to the motor shaft 22, and the stator is fixed to the inner wall of the casing 21. When the motor 20 is powered on, the rotor can rotate relative to the stator. Since the mounting bracket is fixedly set, the motor shaft 22 is relatively fixed, and the rotor is also fixedly set with the motor shaft 22. Therefore, the motor 20 is equivalent to an external rotor motor 20, and the stator is equivalent to rotating around the rotor, thereby driving the housing 10 to rotate around the motor shaft 22.

[0029] Three fan blades 30 are provided above the housing 10, and the three fan blades 30 are evenly arranged around the housing 10 at 120° intervals. The fan blades 30 are rotatably connected to the housing 10, and the fan blades 30 can be stored above the housing 10. When the housing 10 rotates, the fan blades 30 rotate synchronously with the housing 10 and unfold outward under the action of centrifugal force, generating a vertically downward airflow when rotating. Of course, in other embodiments of the present invention, the number of fan blades 30 is not limited and can be set as needed.

[0030] like Figure 4 As shown, specifically, the end of the fan blade 30 is provided with a fixing part 31, and the fan blade 30 is pivotally connected to the housing 10 through the fixing part 31. The fixing part 31 is columnar and includes a first annular wall 311 and a second annular wall 312 extending toward the housing 10. The first annular wall 311 and the second annular wall 312 are nested together, and the first annular wall 311 is arranged around the outside of the second annular wall 312.

[0031] Combination Figure 3 and Figure 5 As shown, an annular channel is formed between the first annular wall 311 and the second annular wall 312. A torsion spring 40 capable of elastic deformation is provided in the annular channel. The first end of the torsion spring 40 is connected to the fan blade 30, and the second end is connected to the housing 10. The torsion spring 40 is configured to generate a force that causes the fan blade 30 to be housed above the housing 10.

[0032] In addition, a reinforcing rib 32 is provided on the outer side of the first annular wall 311, and the reinforcing rib 32 is used to connect the fan blade 30 and the fixing part 31.

[0033] It is understandable that when the housing 10 rotates under the drive of the motor 20, the fan blade 30 is subjected to centrifugal force and overcomes the elastic force of the torsion spring 40, thus unfolding outward. When the housing 10 stops rotating, the centrifugal force disappears, and under the action of the torsion spring 40, the fan blade 30 retracts back to above the housing 10.

[0034] Furthermore, a groove 313 is formed on the second annular wall 312, and the first end of the torsion spring 40 extends radially along the second annular wall 312 and is engaged in the groove 313. When the fan blade 30 rotates, the groove 313 in the second annular wall 312 abuts against the first end of the torsion spring 40, thereby causing the torsion spring 40 to undergo elastic deformation.

[0035] Combination Figure 7 and Figure 8 As shown, the housing 10 is provided with a mounting base 11 for mounting the fixing part 31. The fixing part 31 is mounted from above the mounting base 11. The mounting base 11 has a sliding groove 111, and an extension 112 extending away from the fixing part 31 is also provided outside the sliding groove 111. A through hole 113 is formed in the extension 112. The second end of the torsion spring 40 passes through the sliding groove 111 and is engaged in the through hole 113. When the fan blade 30 rotates relative to the housing 10, the first end and the second end of the torsion spring 40 rotate relative to each other, thereby generating elastic deformation.

[0036] It should be noted that the mounting base 11 does not abut against the fixing part 31. A receiving cavity 101 is formed in the mounting base 11. The opening direction of the receiving cavity 101 is vertically downward. The top of the receiving cavity 101 has a mounting hole for the fastener 60 to pass through. A bearing 50 is provided in the receiving cavity 101. The outer ring of the bearing 50 is fixedly connected to the inner wall of the receiving cavity 101. That is, the outer ring of the bearing 50 is fixedly connected to the housing 10.

[0037] The fan blade 30 and the mounting base 11 are fixedly connected by a fastener 60. The fastener 60 passes sequentially from top to bottom through the fixing part 31, the mounting hole, and the inner ring of the bearing 50, and is fixedly connected to the inner ring of the bearing 50, allowing the fan blade 30 to rotate freely around the mounting base 11 via the bearing 50. The lower end of the fastener 60 is also threaded, and a nut 61 that mates with the fastener 60 is provided outside the thread. The nut 61 abuts against and fixes the inner ring of the bearing 50, thus fixing the fan blade 30 and the inner ring of the bearing 50 in the vertical direction. Furthermore, a washer 62 is provided between the nut 61 and the bearing 50.

[0038] like Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the mounting base 11 is further provided with a first limiting portion 114 and a second limiting portion 115 for limiting the rotation angle of the fan blade 30, both of which extend vertically upward. It should be noted that the extension portion 112, the first limiting portion 114, and the second limiting portion 115 are all part of the housing 10 and are formed by bending a portion of the housing 10, thereby reducing material and weight.

[0039] On the outer side of the fixing part 31, that is, outside the first annular wall 311, there is an outwardly protruding part 33. An arc-shaped track is formed between the first limiting part 114 and the second limiting part 115 for the protruding part 33 to reciprocate. The first limiting part 114 and the second limiting part 115 can limit the movement of the protruding part 33 on both sides, thereby limiting the rotation angle of the fan blade 30.

[0040] The first limiting part 114 is used to limit the maximum rotation angle of the fan blade 30. That is, when the housing 10 rotates, the fan blade 30 unfolds relative to the housing 10, the protrusion 33 abuts against the first limiting part 114, and the fan blade 30 rotates to the maximum rotation angle.

[0041] The second limiting part 115 is used to limit the angle of inward rotation of the fan blade 30. When the housing 10 is in a non-rotating state, the torsion spring 40 is configured to generate a force that causes the protrusion 33 to abut against the second limiting part 115, so as to prevent the fan blade 30 from interfering with other fan blades 30 or colliding with other parts of the fan light 100.

[0042] Specifically, when the protrusion 33 abuts against the second limiting part 115, the orthographic projection of the fan blade 30 on the horizontal plane completely overlaps with the orthographic projection of the housing 10 on the horizontal plane.

[0043] Furthermore, the fan light 100 also includes a light source module for illumination. The light source module is not limited to being disposed above or below the housing 10, as long as it can be used for illumination. The light source module can rotate synchronously with the housing 10, or it can be disposed independently. The housing 10 does not affect the light source module when it rotates, so that they do not interfere with each other.

[0044] In summary, by placing the bearing 50 at the bottom of the mounting base 11, the present invention can prevent dust from entering the bearing 50, thereby reducing the friction between the fan blade 30 and the housing 10, simplifying the structure and reducing costs. In addition, no additional lubricating oil is required, which improves assembly efficiency and reliability.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
