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 simplifies the structure.

[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 fan blades have a fixing part, which is pivotally connected to the housing via a bearing. The fixing part has an upward-facing receiving cavity for accommodating the bearing. The opening of the receiving cavity is provided with a fixing cover that cooperates with and is fixed to the fixing part. The orthographic projection of the fixing cover on the horizontal plane partially overlaps with the orthographic projection of the bearing on the horizontal plane.

[0006] As a further improvement of the present invention, the fixing part includes a base plate for connecting the fan blade, the base plate is horizontally arranged, and the base plate is provided with a first annular wall extending away from the housing, the receiving cavity is surrounded by the first annular wall, and the outer ring of the bearing is fixed to the first annular wall, the inner ring of the bearing is provided with a fastener, and the fastener is used to connect the fixing part and the housing in the vertical direction.

[0007] As a further improvement of the present invention, the substrate is further provided with at least one snap-fit ​​portion located outside the first annular wall, and the fixing cover is formed with a mounting groove corresponding to the snap-fit ​​portion. The snap-fit ​​portion includes a first wall extending vertically upward and a second wall connected to the first wall and extending horizontally. A portion of the mounting groove is provided with an abutment wall. After the snap-fit ​​portion passes through the mounting groove, the first wall and the second wall abut against the abutment wall simultaneously by rotating the fixing cover.

[0008] As a further improvement of the present invention, the substrate is further provided with at least one positioning part located outside the first annular wall, and the fixing cover is formed with an elastic part corresponding to the positioning part. The positioning part is provided with a first inclined surface facing the elastic part and a first abutting surface facing away from the mounting groove. The elastic part is provided with a second inclined surface facing the positioning part and a second abutting surface facing the mounting groove. When the fixing cover is rotated, the first inclined surface moves relative to the second inclined surface, causing the elastic part to undergo elastic deformation, thereby causing the first abutting surface and the second abutting surface to abut against each other.

[0009] As a further improvement of the present invention, the fixing part further includes a second annular wall and a third annular wall extending toward the housing, and a torsion spring sleeved outside the third annular wall is accommodated between the second annular wall and the third annular wall, and the two ends of the torsion spring are respectively fixed to the housing and the fan blade.

[0010] As a further improvement of the present invention, the second annular wall is arranged around the outside of the third annular wall, and a fixing hole is formed on the third annular wall. The first end of the torsion spring is engaged in the fixing hole. A reinforcing rib is also provided on the outside of the second annular wall, and the reinforcing rib is used to connect the fan blade and the fixing part.

[0011] As a further improvement of the present invention, the housing is provided with a mounting seat for mounting the fixing part, the fixing part is mounted from above the mounting seat, the mounting seat is provided with a sliding groove, and the second end of the torsion spring passes through the sliding groove and abuts against the sliding groove.

[0012] As a further improvement of the present invention, the mounting base is further provided with a support member sleeved outside the fastener. The support member is disposed inside the third annular wall and is used to abut against the bearing and the housing respectively. The fastener passes through the bearing, the support member, the base plate and the housing in sequence. A nut for fastening the fastener is also provided below the housing.

[0013] 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 second 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.

[0014] 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.

[0015] The beneficial effects of the present invention are as follows: by setting the bearing at the upper end of the fixed part and preventing the bearing from falling out by using a fixed cover, and by setting a torsion spring in the fixed part, the present invention can simplify the structure and reduce costs. In addition, no additional lubricating oil is required, which improves assembly efficiency and reliability. Attached Figure Description

[0028] 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.

[0029] 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.

[0030] 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.

[0031] like Figures 1 to 12 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.

[0032] Combination Figure 2 and Figure 3 As 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, a motor shaft, a rotor, and a stator. The casing and the motor 20 are located at the center of the housing 10, and the casing is integrally formed with the housing 10. The motor shaft 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, and the stator is fixed to the inner wall of the casing. 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 is relatively fixed, and the rotor is also fixedly set with the motor shaft. 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.

[0033] 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.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, specifically, the end of the fan blade 30 is provided with a fixing part 31. 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 base plate 301 for connecting the fan blade 30. The base plate 301 is horizontally arranged and parallel to the housing 10. The base plate 301 is provided with a first annular wall 311 extending away from the housing 10. That is, with the ceiling as a reference frame, the first annular wall 311 extends upward. The first annular wall 311 surrounds and forms a receiving cavity 3111. A bearing 40 is provided in the receiving cavity 3111. A fastener 50 is provided in the bearing 40, which passes through the bearing 40 and the base plate 301 in sequence. The other end of the fastener 50 is fixed to the housing 10. The outer ring of the bearing 40 is fixed to the first annular wall 311, and the inner ring of the bearing 40 is fixed to the fastener 50, so that the fixing part 31 can rotate around the fastener 50.

[0035] Preferably, the upper end of the substrate 301 is further provided with a fixing cover 60 for fixing the bearing 40. The orthographic projection of the fixing cover 60 on the horizontal plane partially overlaps with the orthographic projection of the bearing 40 on the horizontal plane, so as to limit the bearing 40 in the vertical direction to prevent the bearing 40 from coming out.

[0036] like Figure 6 As shown, the substrate 301 is also provided with at least one snap-fit ​​portion 302 located outside the first annular wall 311. The fixing cover 60 is formed with a mounting groove 61 corresponding to the snap-fit ​​portion 302. The number of mounting grooves 61 is the same as the number of snap-fit ​​portions 302, and preferably, there are two snap-fit ​​portions 302 and two mounting grooves 61. The snap-fit ​​portion 302 includes a first wall 3021 extending vertically upward and a second wall 3022 connected to the first wall 3021 and extending horizontally. A portion of the mounting groove 61 is provided with an abutment wall 611. After the snap-fit ​​portion 302 passes through the mounting groove 61, that is, after the second wall 3022 passes through the mounting groove 61 vertically, the fixing cover 60 is rotated in a first direction so that the first wall 3021 and the second wall 3022 simultaneously abut against the abutment wall 611. The first wall 3021 abuts against the abutment wall 611 from the side, and the abutment wall 611 is used to support the second wall 3022 in the vertical direction. The fixing cover 60 and the base plate 301 are fixed in the first direction.

[0037] like Figure 7 and Figure 8As shown, the substrate 301 is further provided with at least one positioning part 303 located outside the first annular wall 311. The fixing cover 60 is formed with an elastic part 62 corresponding to the positioning part 303. The number of elastic parts 62 is the same as the number of positioning parts 303. Preferably, there are two elastic parts 62 and two positioning parts 303. The positioning part 303 and the snap-fit ​​part 302 are spaced apart on the substrate 301, and the elastic part 62 and the mounting groove 61 are spaced apart on the fixing cover 60.

[0038] Combination Figure 11 and Figure 12 As shown, the positioning part 303 has a first inclined surface 3031 facing the elastic part 62 and a first abutting surface 3032 facing away from the mounting groove 61. The elastic part 62 has a second inclined surface 621 facing the positioning part 303 and a second abutting surface 622 facing the mounting groove 61. When the fixed cover 60 rotates in the second direction, the first inclined surface 3031 moves relative to the second inclined surface 621, causing the elastic part 62 to undergo elastic deformation, thereby causing the first abutting surface 3032 and the second abutting surface 622 to abut against each other.

[0039] like Figure 9 and Figure 10 As shown, the fixing part 31 also includes a second annular wall 312 and a third annular wall 313 extending toward the housing 10. The second annular wall 312 and the third annular wall 313 are nested together, and the second annular wall 312 is arranged around the outside of the third annular wall 313.

[0040] An annular channel is formed between the second annular wall 312 and the third annular wall 313. A torsion spring 70 capable of elastic deformation is provided in the annular channel. The first end of the torsion spring 70 is connected to the fan blade 30, and the second end is connected to the housing 10. The torsion spring 70 is configured to generate a force that causes the fan blade 30 to be housed above the housing 10.

[0041] In addition, a reinforcing rib is provided on the outer side of the second annular wall 312, which is used to connect the fan blade 30 and the fixing part 31.

[0042] 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 70, and then unfolds outward. When the housing 10 stops rotating, the centrifugal force disappears, and under the action of the torsion spring 70, the fan blade 30 retracts back to above the housing 10.

[0043] Furthermore, a fixing hole (not shown) is formed on the third annular wall 313. The first end of the torsion spring 70 extends radially along the third annular wall 313 and is engaged in the fixing hole. When the fan blade 30 rotates, the fixing hole in the third annular wall 313 abuts against the first end of the torsion spring 70, thereby causing the torsion spring 70 to undergo elastic deformation.

[0044] Combination Figure 2 and Figure 3 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 is provided with a sliding groove 111. The second end of the torsion spring 70 passes through the sliding groove 111 and abuts against the sliding groove 111. When the fan blade 30 rotates relative to the housing 10, the first end and the second end of the torsion spring 70 rotate relative to each other, thereby generating elastic deformation.

[0045] Combination Figure 3 and Figure 4 As shown, the mounting base 11 also includes a support member 112 sleeved around the fastener 50. The support member 112 is disposed within the third annular wall 313 and serves to abut against the bearing 40 and the housing 10 respectively. The fastener 50 passes through the bearing 40, the support member 112, the base plate 301, and the housing 10 sequentially from top to bottom. The lower end of the fastener 50 is threaded, and a nut 113 is provided outside the thread to mate with the fastener 50, allowing the fan blade 30 to rotate freely around the mounting base 11 via the bearing 40. Furthermore, a washer is provided between the nut 113 and the bearing 40.

[0046] Combination Figure 1 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 the first limiting portion 114 and the second limiting portion 115 extend vertically upward. It should be noted that both the first limiting portion 114 and the second limiting portion 115 are part of the housing 10 and are formed by bending a portion of the housing 10, thereby reducing material and weight.

[0047] On the outer side of the fixing part 31, i.e. the outer side of the second annular wall 312, there is an outwardly protruding part 32. An arc-shaped track is formed between the first limiting part 114 and the second limiting part 115 for the reciprocating movement of the protruding part 32. The first limiting part 114 and the second limiting part 115 can limit the movement of the protruding part 32 on both sides, thereby limiting the rotation angle of the fan blade 30.

[0048] 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 32 abuts against the first limiting part 114, and the fan blade 30 rotates to the maximum rotation angle.

[0049] 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 70 is configured to generate a force that causes the protrusion 32 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.

[0050] Specifically, when the protrusion 32 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.

[0051] 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.

[0052] In summary, by placing the bearing 40 on the upper end of the fixing part 31 and preventing the bearing 40 from falling out by the fixing cover 60, and by providing a torsion spring 70 inside the fixing part 31, the present invention simplifies the structure and reduces costs. In addition, no additional lubricating oil is required, which improves assembly efficiency and reliability.

[0053] 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.
