Description

Technical Field

[0001] This utility model relates to the field of ceiling fan technology, and in particular to the blade mounting structure of a ceiling fan and the ceiling fan thereof. Background Technology

[0002] In the field of ceiling fan blade installation technology, traditional installation methods primarily rely on screws and other fasteners to secure the blades to the mounting body. Specifically, installers typically need to work at height, first lifting the blade and roughly aligning its mounting holes with the corresponding connection holes on the mounting body. During this process, the installer must support the blade with one hand to maintain its position and prevent accidental detachment, while simultaneously using the other hand to hold the screw and insert it into the blade's mounting hole. Further fine-tuning of the blade's position ensures the screw is precisely aligned with the threaded hole on the mounting body. Subsequently, a screwdriver or power tool is used to tighten the screw, completing the single-screw fixing. For blades with multiple mounting points, the above steps must be repeated until all connection points are reliably secured.

[0003] However, this traditional installation method has significant drawbacks. Because the blades must be supported with one hand for extended periods during installation, it not only increases the physical burden on operators but also poses a risk of the blades falling if not fully secured. Furthermore, the need for separate alignment and securing steps, coupled with manual fine-tuning, leads to low installation efficiency and prolonged overall operation time. In addition, if the screws are not aligned accurately on the first attempt, it can easily damage the threaded holes or strip the screws, further affecting installation quality and structural reliability.

[0004] Therefore, it is necessary to propose a new type of ceiling fan blade installation structure to overcome the problems of low operating efficiency and high operating difficulty in the existing technology. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a blade mounting structure for ceiling fans that can improve installation efficiency and reduce operational difficulty.

[0006] This utility model also proposes a ceiling fan having the above-mentioned blade mounting structure.

[0007] The blade mounting structure of the ceiling fan according to a first aspect embodiment of the present invention includes: The blades are equipped with snap-fit ​​holes; The main body of the suspension has an installation channel. The bottom wall of the installation channel is constructed as a deformable wall. The deformable wall has a snap-fit ​​protrusion on the side facing the installation channel. The deformable wall can produce elastic deformation to drive the snap-fit ​​protrusion to move. During the process of inserting the blade into the mounting channel, there are a first state and a second state. In the first state, the snap-fit ​​protrusion abuts against the top surface of the blade, causing the deformation wall to deform in a direction away from the blade. In the second state, the position of the snap-fit ​​protrusion is aligned with the position of the snap-fit ​​hole, the deformation wall is reset, and the snap-fit ​​protrusion is driven into the snap-fit ​​hole to prevent the blade from detaching from the mounting channel.

[0008] The blade mounting structure of the ceiling fan according to this utility model embodiment has at least the following beneficial effects: by constructing the entire bottom wall area of ​​the mounting channel as a deformable wall, and providing a snap-fit ​​protrusion on the side of the deformable wall facing the mounting channel, the deformable wall can elastically deform during the blade installation process, causing the snap-fit ​​protrusion to avoid the blade. After the blade is installed in place, the repositioning of the deformable wall causes the snap-fit ​​protrusion to engage with the snap-fit ​​hole, thus fixing the blade to the hanging body. The blade installation efficiency is greatly improved, and the installation difficulty is significantly reduced.

[0009] According to some embodiments of the present invention, the snap-fit ​​protrusion is integrally formed with the deformable wall.

[0010] According to some embodiments of the present invention, the snap-fit ​​protrusion includes a first inclined portion and a second inclined portion. The first inclined portion and the second inclined portion are arranged along the insertion direction perpendicular to the blade. The side of the first inclined portion away from the second inclined portion is fixedly connected to the deformation wall, and the other side is inclined toward the blade and connected to the second inclined portion. The side of the second inclined portion away from the first inclined portion is fixedly connected to the deformation wall, and the other side is inclined toward the blade.

[0011] According to some embodiments of the present invention, the first connecting line formed at the connection between the first inclined portion and the second inclined portion is inclined toward the blade along the insertion direction of the blade.

[0012] According to some embodiments of the present invention, the end of the blade is provided with a guide notch at the position corresponding to the snap-fit ​​protrusion, and the shape of the guide notch matches the outer contour shape of the snap-fit ​​protrusion.

[0013] According to some embodiments of the present invention, the deformable wall is provided with a pressing protrusion on the side facing the mounting channel. In the first state, the pressing protrusion is separated from the blade; in the second state, the pressing protrusion abuts against the top surface of the blade.

[0014] According to some embodiments of the present invention, the hanging body is provided with a limiting part. In the first state, the limiting part is separated from the blade; in the second state, the limiting part abuts against the side of the blade.

[0015] According to some embodiments of the present invention, the deformable wall is provided with a flange, and the flange is folded away from the blade.

[0016] According to some embodiments of the present invention, the blade mounting structure further includes a disassembly component. In the second state, the disassembly component is used to insert into the gap between the blade and the deformed wall and push the snap-fit ​​protrusion away from the snap-fit ​​hole, so that the blade can be pulled out of the mounting channel.

[0017] The ceiling fan according to a second aspect of the present invention includes the blade mounting structure of the ceiling fan according to the first aspect of the present invention.

[0018] The ceiling fan according to the embodiments of the present utility model has at least the following beneficial effects: by adopting the blade mounting structure of the ceiling fan of the first aspect embodiment of the present utility model, the installation efficiency can be improved and the operation difficulty can be reduced.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0025] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0026] In related technologies, several connection solutions for fixing ceiling fan blades have been proposed to replace traditional screw connections. For example, the first solution uses a spring combined with a locking pin or ball bearing. The spring's elastic force presses the locking pin or ball bearing into the corresponding groove at the blade end, achieving rapid blade positioning and fixing. The second solution involves directly stamping an elastic sheet onto the connector above the blade. One end of this elastic sheet is fixed and connected to the connector body, while the other end is free and can be snapped into the corresponding groove on the blade, thus achieving a snap-fit ​​fixation of the blade.

[0027] However, both of the above solutions have certain limitations. The first spring-locking pin / ball bearing structure requires a large number of parts, increasing the overall complexity and size of the structure, leading to more assembly steps and higher installation difficulty, which is detrimental to improving assembly efficiency and controlling costs. The second elastic plate snap-fit ​​solution, while effective under light loads or low speeds, is prone to plastic deformation or fatigue relaxation under high speeds and heavy-mass blade conditions, as the elastic plate continuously bears significant centrifugal force and vibration loads, resulting in loose blade connections and potential safety hazards. Furthermore, to ensure the connection strength at the fixed end of the elastic plate, the connector typically needs to be thicker, which not only increases material costs but also limits the lightweight and flexible nature of the structural design.

[0028] The following reference Figures 1 to 6 This invention describes the blade 100 mounting structure of the ceiling fan according to an embodiment of the present invention and how the ceiling fan solves the above-mentioned problems.

[0029] Reference Figure 1 The first aspect of this utility model describes a ceiling fan blade 100 mounting structure, which includes blades 100 and a hanging body 200. The blades 100 are provided with snap-fit ​​holes 110. (See reference...) Figure 3 and Figure 4The main body 200 is provided with an installation channel 220. The bottom wall of the installation channel 220 is constructed as a deformable wall 211. The deformable wall 211 has a snap-fit ​​protrusion 230 on the side facing the installation channel 220. The deformable wall 211 can generate elastic deformation to drive the snap-fit ​​protrusion 230 to move. For example, the main body 200 includes a blade holder plate 210, which is located below the blade 100. The blade holder plate 210 is made of metal or plastic. The portion of the blade holder plate 210 corresponding to the plane 120 of the blade 100 constitutes the deformable wall 211. The deformable wall 211 has a large area, and the material and thickness of the blade holder plate 210 ensure that the deformable wall 211 can generate elastic deformation in a direction perpendicular to the plane 120 of the blade 100. The extension direction of the deformable wall 211 is the same as the extension direction of the bottom wall of the mounting channel 220, and it does not extend into the mounting channel 220. However, the extension direction of the snap-fit ​​protrusion 230 is different from the extension direction of the bottom wall of the mounting channel 220, and the snap-fit ​​protrusion 230 extends into the mounting channel 220.

[0030] During the insertion of the blade 100 into the mounting channel 220, there are two states. In the first state, the locking protrusion 230 abuts against the top surface of the blade 100, causing the deformation wall 211 to deform away from the blade 100. In the second state, the position of the locking protrusion 230 is aligned with the position of the locking hole 110, the deformation wall 211 returns to its original position, and the locking protrusion 230 is engaged in the locking hole 110, thus preventing the blade 100 from disengaging from the mounting channel 220. That is, when the blade 100 is inserted into the mounting channel 220, but before the blade 100 contacts the locking protrusion 230, the locking protrusion 230 will interfere with the blade 100 along the movement path of the blade 100. When the blade 100 contacts the locking protrusion 230, the force between the blade 100 and the locking protrusion 230 is transmitted to the deformation wall 211, causing the deformation wall 211 to undergo elastic deformation. This causes the locking protrusion 230 to move away from the blade 100, allowing the locking protrusion 230 to avoid the blade 100. When the locking hole 110 moves directly above the locking protrusion 230, the force between the blade 100 and the locking protrusion 230 disappears, the deformation wall 211 resets, and the locking protrusion 230 moves toward the locking hole 110 and eventually enters the locking hole 110.

[0031] Understandably, along the insertion direction of the blade 100, one side of the locking protrusion 230 is designated as a guide surface, and the other side as a stop surface. The distance between the guide surface and the blade 100 gradually decreases along the insertion direction of the blade 100, and the guide surface is nearly perpendicular to the plane 120 of the blade 100. Thus, during the insertion of the blade 100 into the installation channel 220, the blade 100 first contacts the guide surface. As the blade 100 continues to penetrate deeper, the force between the blade 100 and the locking protrusion 230 has a component force that causes the deformation wall 211 to deform slowly. The deformation of the deformation wall 211 drives the locking protrusion 230 to move, allowing the blade 100 to smoothly enter the installation channel 220. When the snap-fit ​​protrusion 230 enters the snap-fit ​​hole 110 and the blade 100 tends to detach from the mounting channel 220, the hole wall of the snap-fit ​​hole 110 abuts against the stop surface. The force between the blade 100 and the snap-fit ​​protrusion 230 is parallel to the direction of movement of the blade 100, which will not cause the deformation wall 211 to deform, thereby effectively fixing the blade 100 in the mounting channel 220.

[0032] Understandably, since the deformable wall 211 needs to be able to produce elastic deformation, the plate thickness of the blade plate 210 forming the deformable wall 211 can be designed to be thinner, saving more materials, making the overall structure lighter, reducing motor load loss, and helping to improve the performance of the ceiling fan.

[0033] Understandably, the snap-fit ​​protrusion 230 can be designed as a rigid structure, meaning it is not easily deformed. During contact between the snap-fit ​​protrusion 230 and the blade 100, and during the operation of the ceiling fan, the snap-fit ​​protrusion 230 maintains its shape, thus ensuring the reliable connection of the blade 100 and preventing loosening. Under conditions of higher speed and greater blade mass, the blade 100 is less likely to detach, resulting in higher safety.

[0034] It is understandable that the snap-fit ​​protrusion 230 and the deformable wall 211 are integrally formed. For example, the blade holder 210 is a sheet metal part, and the snap-fit ​​protrusion 230 is formed by stamping on the sheet metal part. The processing is simple, there is no additional material cost, the overall structure is lightweight, the motor load loss is reduced, and it is beneficial to improve the performance of the ceiling fan.

[0035] Reference Figure 1 and Figure 2The snap-fit ​​protrusion 230 includes a first inclined portion 231 and a second inclined portion 232. The first inclined portion 231 and the second inclined portion 232 are arranged along the insertion direction perpendicular to the blade 100. Both the first inclined portion 231 and the second inclined portion 232 extend inclinedly from the deformable wall 211 toward the mounting channel 220 and intersect at the middle position of the snap-fit ​​protrusion 230. Specifically, the side of the first inclined portion 231 away from the second inclined portion 232 is fixedly connected to the deformable wall 211, and the other side is inclined toward the blade 100 and connected to the second inclined portion 232. The side of the second inclined portion 232 away from the first inclined portion 231 is fixedly connected to the deformable wall 211, and the other side is inclined toward the blade 100.

[0036] Reference Figure 1 and Figure 2 The first connecting line 233 formed at the junction of the first inclined portion 231 and the second inclined portion 232 is inclined towards the blade 100 along the insertion direction of the blade 100, so that the plane 120 of the first inclined portion 231 and the second inclined portion 232 on the side close to the blade 100 together constitutes a guide surface. Correspondingly, the end faces of the first inclined portion 231 and the second inclined portion 232 on the side away from the blade 100 constitute a stop surface. The junction of the first inclined portion 231 and the deformation wall 211 forms a second connecting line 234, and the junction of the second inclined portion 232 and the deformation wall 211 forms a third connecting line 235. The first connecting line 233, the second connecting line 234, and the third connecting line 235 intersect. That is, along the insertion direction of the blade 100, the width of the locking protrusion 230 gradually increases. The width of the locking protrusion 230 refers to the distance between the two sides of the locking protrusion 230 along the arrangement direction of the first inclined portion 231 and the second inclined portion 232. This increases the distance between the contact point between the stop surface and the blade 100, which helps improve the contact stability between the snap-fit ​​protrusion 230 and the blade 100.

[0037] Understandably, the connection area between the snap-fit ​​protrusion 230 and the deformation wall 211 forms a triangle, with the base of the triangle perpendicular to the direction of movement of the blade 100. As the blade 100 enters the mounting channel 220, it first passes through the angle corresponding to the base of the triangle, and finally passes through the base itself. The area of ​​the deformation wall 211 corresponding to the base of the triangle experiences less deformation than the area corresponding to the angle, thus better preventing the blade 100 from detaching from the mounting channel 220.

[0038] Reference Figure 1The blade 100 has a guide notch 140 at the end corresponding to the snap-fit ​​protrusion 230. The shape of the guide notch 140 matches the outer contour of the snap-fit ​​protrusion 230. The guide notch 140, in conjunction with the snap-fit ​​protrusion 230, guides the snap-fit ​​protrusion 230 to slide smoothly into the correct position during initial insertion, providing centering and guidance, making the snap-fit ​​process smoother and more accurate. In other words, through the guide notch 140 matching the contour of the snap-fit ​​protrusion 230, the snap-fit ​​protrusion 230 can be positioned during the initial insertion of the blade 100, preventing misalignment during insertion and ensuring that the snap-fit ​​hole 110 is precisely aligned with the snap-fit ​​protrusion 230. This reduces installation difficulty and is especially suitable for the rapid operation requirements in high-altitude work scenarios.

[0039] Reference Figures 1 to 4 The deformable wall 211 has a clamping protrusion 240 on the side facing the mounting channel 220. In the first state, the clamping protrusion 240 is separated from the blade 100; in the second state, the clamping protrusion 240 abuts against the top surface of the blade 100 to prevent the blade 100 from loosening. The blade holder disk 210 is a sheet metal part, and a recessed area is formed by stamping on the sheet metal part. The clamping protrusion 240 is formed on one side of the mounting channel 220 corresponding to the recessed area. When the blade 100 is inserted into the mounting channel 220, the locking protrusion 230 is pushed by the top surface of the blade 100, which drives the deformable wall 211 to deform upward. At this time, the clamping protrusion 240 moves upward synchronously with the deformable wall 211, keeping it separated from the top surface of the blade 100 to avoid obstructing the insertion of the blade 100. When the snap-fit ​​protrusion 230 snaps into the snap-fit ​​hole 110, the deformable wall 211 resets and sinks, and the clamping protrusion 240 moves down accordingly and tightly abuts against the top surface of the blade 100. Through continuous elastic pressure (the pre-tightening force after the deformable wall 211 resets), the clamping protrusion 240 presses the blade 100 into the installation channel 220, eliminating the gap between the blade 100 and the channel wall, preventing the blade 100 from loosening or making abnormal noise due to vibration or centrifugal force during operation of the ceiling fan, and compensating for the gap defects that may exist if the positioning is only achieved by the snap-fit ​​protrusion 230. The use of sheet metal stamping to form the recessed groove and the clamping protrusion 240 as a whole eliminates the need for additional parts and reduces assembly steps; at the same time, it avoids the problem of thickening the sheet metal to enhance the strength of the elastic sheet in Scheme 2, reducing material costs and processing complexity while ensuring structural strength, and is more conducive to mass production.

[0040] Reference Figure 3The suspension body 200 is provided with a limiting part 250. In a first state, the limiting part 250 is separated from the blade 100; in a second state, the limiting part 250 abuts against the side surface 130 of the blade 100. The limiting part 250 can be constructed as a folded edge provided at the end of the blade holder disk 210 away from the blade 100. The folded edge is integrally formed with the blade holder disk 210 and extends inward toward the mounting channel 220 to form a blocking surface corresponding to the side surface 130 of the blade 100, which can limit the offset of the blade 100 perpendicular to the insertion direction. When the blade 100 is inserted into the snap-fit ​​position, its side surface 130 abuts against the folded edge of the limiting part 250. The folded edge restricts the outward displacement of the blade 100 through its own structural strength. Combined with the radial pressing of the pressing protrusion 240 on the top surface of the blade 100 and the axial locking of the blade 100 by the snap-fit ​​protrusion 230, a triple fixing structure is formed, which limits the multi-directional freedom of the blade 100 within the installation channel 220. When the blade 100 rotates at high speed, it can reduce the abnormal noise caused by the loosening of the blade 100 and improve the comfort and quietness effect.

[0041] Reference Figures 1 to 4 The deformable wall 211 has a flange 260, which folds away from the blade 100. The flange 260 is integrally formed with the blade holder disk 210 at the end near the blade 100. The flange 260, folded outwards (away from the blade 100), at the end of the deformable wall 211 acts as a flared opening or guide ramp at the entrance of the mounting channel 220. This effectively increases the effective size at the entrance, allowing the blade 100 to slide into the correct mounting channel 220 even with slight positional deviations during insertion, preventing the blade 100 from blocking the entrance of the mounting channel 220 and being unable to be pushed in.

[0042] Reference Figure 5 The blade 100 mounting structure also includes a disassembly member 300. In the second state, the disassembly member 300 is used to insert into the gap between the blade 100 and the deformable wall 211, and push the locking protrusion 230 out of the locking hole 110, so that the blade 100 can be withdrawn from the mounting channel 220. When the blade 100 is in the locked second state, there is a small gap between the bottom surface of the blade 100 and the upper surface of the deformable wall 211. The disassembly member 300 is designed to be inserted into this gap. When the disassembly member 300 presses down on the deformable wall 211, it forces the deformable wall 211 to elastically deform again, thereby causing the locking protrusion 230 on it to move upward and exit from the locking hole 110 of the blade 100. Once the locking protrusion 230 is disengaged, the axial locking of the blade 100 is released, and the blade 100 can then be withdrawn from the mounting channel 220.

[0043] It should be noted that in some other embodiments, the snap-fit ​​protrusion 230, the pressing protrusion 240, and the limiting part 250 may also be separate parts, which are connected to the blade carrier disk 210 by welding or other means.

[0044] Reference Figure 6 The ceiling fan of the second aspect of this utility model includes the blade 100 mounting structure of the ceiling fan of the first aspect of this utility model. The ceiling fan also includes an annular outer shell 400, in which a mounting base 500 is provided. The mounting base 500 can be used to mount a motor. The mounting base 500 and the annular outer shell 400 form an annular groove 600. The blade holder 210 is installed in the annular groove 600. The blade holder 210 and the annular groove 600 together define a mounting channel 220. A clearance hole 401 is provided on the circumferential surface of the annular outer shell 400. The position of the clearance hole 401 corresponds to the position of the mounting channel 220. The blade 100 passes through the clearance hole 401 and is inserted into the mounting channel 220.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
