Description

Technical Field

[0001] This application relates to the field of fan technology, and in particular to a positioning structure and a fan. Background Technology

[0002] Currently, most fan components are fixed to the second component via a knob. This knob is secured to the first component by axial pressure, offering no circumferential limiting effect and making assembly / disassembly complex. Different users apply different installation pressures; excessive pressure can cause the knob to strip, preventing a secure fixation between the first and second components. This leads to imbalance during rotation of the first component, causing the fan grille to vibrate, and the positioning structure exhibits poor structural stability. Summary of the Invention

[0039] Please refer to Figure 1 In one embodiment, the fan includes a positioning structure 300.

[0040] Specifically, the aforementioned fan also includes a body, a head, a first component 100, and a second component 200. The head is fixed to the top of the body, the first component 100 and the second component 200 are disposed on the head and used to drive airflow, and the positioning structure 300 is used to fix the first component 100 and the second component 200.

[0041] In the above embodiments, the first component 100 is a fan blade, and the second component 200 is a motor shaft. The first component 100 rotates by rotating the motor shaft. Specifically, the positioning structure includes a motor, which includes a body and a motor shaft connected to the body. The motor shaft is fixedly connected to the first component 100. The motor type can be a servo motor, a stepper motor, or other types; the type of motor is not specifically limited here. In other embodiments, the second component 200 can also be other types of rotatable drive shafts, and the first component 100 and the second component 200 can also be other components.

[0042] Please refer to Figures 1 to 3 In one embodiment, the positioning structure 300 is used to fix the second component 200 and the first component 100. The second component 200 has a limiting groove 201. The positioning structure 300 includes a first fixing member 310 and a second fixing member 320. The second fixing member 320 is fixedly connected to the first component 100. The first fixing member 310 is movably inserted into the second fixing member 320 along a first direction. The second component 200 passes through the first fixing member 310 and the second fixing member 320 along a second direction perpendicular to the first direction.

[0043] Among them, reference Figure 3 The first fixing member 310 has a locking part 311 and an anti-detachment part 312 that is locked to the second fixing member 320. When the second component 200 is inserted into the first fixing member 310, the second component 200 pushes against the anti-detachment part 312 and causes it to detach from the second fixing member 320. The first fixing member 310 moves along the first direction and causes the locking part 311 to be locked in place with the limiting groove 201.

[0044] It should be noted that the first direction is Figure 3 The X direction shown is the radial direction of the second component 200. The second direction is... Figure 3 The Y direction shown is the axial direction of the second component 200.

[0045] In the aforementioned positioning structure, the first fixing member 310 is movably inserted into the second fixing member 320 along the first direction, and the anti-detachment part 312 of the first fixing member 310 is engaged with the second fixing member 320, which can effectively prevent the first fixing member 310 and the second fixing member 320 from separating, and at the same time realize the circumferential self-positioning of the second component 200 and the first component 100; through the limiting part 311 and the limiting groove 201, the axial positioning of the second component 200 and the first component 100 is realized, thereby making the second component 200 and the first component 100 axially and circumferentially fastened, improving the structural stability of the positioning structure.

[0046] For specific implementation details, please refer to the following examples. Figure 3The first fixing member 310 is provided with a first shaft hole 313 for the second component 200 to pass through, the locking part 311 is provided on the inner wall of the first shaft hole 313, and the anti-detachment part 312 is provided outside the first shaft hole 313 and is opposite to the locking part 311.

[0047] With the above configuration, the locking part 311 and the anti-detachment part 312 will not interfere with each other, thereby improving the space utilization rate of the first fastener 310.

[0048] In this embodiment, the cross-section of the second component 200 is D-shaped, and correspondingly, the first shaft hole 313 is also D-shaped to fit the second component 200. In other embodiments, the cross-section of the second component 200 may also be square or other shapes, and correspondingly, the first shaft hole 313 may also be square or other shapes.

[0049] Please refer to some embodiments of this application. Figure 3 The second fixing member 320 is provided with a second shaft hole 321 for the second component 200 to pass through. The second shaft hole 321 overlaps at least partially with the first shaft hole 313 in the second direction. The anti-detachment part 312 is engaged in the second shaft hole 321 and is located on the side of the second component 200 away from the limiting groove 201.

[0050] Here, the second shaft hole 321 and the first shaft hole 313 at least partially overlap in the second direction. This can be understood as the second shaft hole 321 and the first shaft hole 313 being fully or partially connected in the second direction. This allows the second component 200 to smoothly pass through the second shaft hole 321 and the first shaft hole 313 along the second direction, preventing the second component 200 from being unable to be installed due to a lack of connection between the second shaft hole 321 and the first shaft hole 313.

[0051] In this embodiment, the cross-section of the second component 200 is D-shaped, and correspondingly, the second shaft hole 321 is also D-shaped to fit the second component 200. In other embodiments, the cross-section of the second component 200 may also be square or other shapes, and correspondingly, the second shaft hole 321 may also be square or other shapes.

[0052] In this embodiment, the inner diameters of the second shaft hole 321 and the first shaft hole 313 are both larger than the outer diameter of the second component 200, so that the second component 200 can pass through the second shaft hole 321 and the first shaft hole 313.

[0053] Please refer to some embodiments of this application. Figure 3 and Figure 6 The anti-detachment part 312 includes a vertically connected fixing plate 312a and a fastening plate 312b. The fixing plate 312a abuts against the second fixing member 320, and the fastening plate 312b passes through and is held in place by the inner wall of the second shaft hole 321.

[0054] With the above arrangement, the fastening plate 312b is inserted through and held in the inner wall of the second shaft hole 321, which can make the anti-detachment part 312 better held in the second shaft hole 321.

[0055] In this embodiment, the fixing plate 312a and the fastening plate 312b are integrally formed structures with fixed dimensions, exhibiting good integrity and high mechanical strength, and facilitating quick assembly and disassembly. In other embodiments, the fixing plate 312a can also be a telescopic structure to change its size, thereby adapting to different sizes of the second shaft hole 321.

[0056] Please refer to some embodiments of this application. Figure 3 The second component 200 has a driving surface 202 on the side opposite to the limiting groove 201. When the second component 200 passes through the first fixing member 310, the driving surface 202 can push against the anti-detachment part 312 to make the anti-detachment part 312 disengage from the second fixing member 320.

[0057] For example, refer to Figure 3 During initial installation, the second component 200 is in the first position, with its driving surface 202 located to the left of the first shaft hole 313; (See reference) Figure 4 The second component 200 is moved to the right in the second direction to the second position, and the driving surface 202 of the second component 200 abuts against the anti-detachment part 312; Reference Figure 5 The second component 200 continues to move to the right to the third position. At this time, the driving surface 202 pushes the anti-detachment part 312 and causes the anti-detachment part 312 to disengage from the second fixing member 320. The first fixing member 310 moves downward along the first direction and causes the limiting part 311 to be locked in the limiting groove 201.

[0058] For details, please refer to Figure 3 The driving surface 202 is either a stepped surface or an inclined surface that expands outwards in a direction away from the central axis of the second component 200. Here, the central axis of the second component 200 is also... Figure 3 The Y direction is shown. In this way, the second component 200 can pass smoothly through the first fixing member 310, and during the insertion process, it drives the first fixing member 310 to move by pushing against the driving surface 202.

[0059] In this embodiment, the driving surface 202 is a smooth plane. In other embodiments, the driving surface 202 may also be curved, or several protrusions may be provided on the driving surface 202 to increase the friction between the driving surface 202 and the second component 200 when the second component 200 abuts against the driving surface 202.

[0060] Please refer to Figure 3 The positioning structure 300 also includes an elastic element 330, which is disposed between the first fixing element 310 and the second fixing element 320 so that the first fixing element 310 can elastically extend and retract along the first direction.

[0061] With the above configuration, the second component 200 is provided with the first fixing member 310 and the second fixing member 320 along the second direction. The first fixing member 310 can elastically extend and retract along the first direction, thereby realizing the circumferential self-positioning of the second component 200 and the first component 100.

[0062] For example, refer to Figure 3 At the start of installation, the second component 200 is in the first position, and the driving surface 202 of the second component 200 is located to the left of the first shaft hole 313. At this time, the elastic element 330 is in a compressed state; see reference. Figure 4 The second component 200 moves to the right along the second direction to the second position, and the driving surface 202 of the second component 200 abuts against the anti-detachment part 312. At this time, the elastic member 330 is in a compressed state; Reference Figure 5 The second component 200 continues to move to the right to the third position. The driving surface 202 pushes the anti-detachment part 312 and causes the anti-detachment part 312 to disengage from the second fixing member 320. Since the elastic member 330 wants to return to its original state, the elastic member 330 will drive the first fixing member 310 to move downward along the radial direction of the second component 200, and cause the limiting part 311 to be locked in the limiting groove 201.

[0063] Optionally, the elastic element 330 is a spring or a sheet spring.

[0064] In this embodiment, the number of elastic elements 330 is one. In other embodiments, the number of elastic elements 330 may be at least two, with all elastic elements 330 arranged side by side along the first direction between the first fixing element 310 and the second fixing element.

[0065] Please refer to some embodiments of this application. Figures 7 to 9 The first fixing member 310 has a first limiting part 314 on the side facing the second fixing member 320, and the second fixing member 320 has a second limiting part 322 on the side facing the first fixing member 310. The two ends of the elastic member 330 elastically abut against the first limiting part 314 and the second limiting part 322 respectively.

[0066] With the above settings, the two ends of the elastic member 330 are respectively limited by the first limiting part 314 and the second limiting part 322, effectively preventing the elastic member 330 from shifting during the extension and retraction process.

[0067] Specifically, in this embodiment, one of the first limiting part 314 and the second limiting part 322 is a limiting post, and the other of the first limiting part 314 and the second limiting part 322 is a fixing groove. The fixing post is cylindrical, and the fixing groove is also a cylindrical groove.

[0068] In other embodiments, the fixing post may also be prismatic or other shapes, and the fixing groove may also be prismatic or other shapes.

[0069] In this embodiment, there is one elastic element 330, and correspondingly, there is one first limiting part 314 and one second limiting part 322. In other embodiments, there may be at least two elastic elements 330, and the number of first limiting parts 314 and second limiting parts 322 is arranged in a one-to-one correspondence with the number of elastic elements 330.

[0070] In this embodiment, one end of the elastic member 330 is detachably connected to the first limiting portion 314, and the other end of the elastic member 330 is detachably connected to the second limiting portion 322. For example, a protrusion is provided on the first limiting portion 314, and one end of the elastic member 330 is sleeved on the first limiting portion 314 and limited on the first limiting portion 314 by the protrusion; or, for another example, a fixing hole is provided on the first limiting portion 314, and a hook is provided on one end of the elastic member 330, so that the hook passes through the fixing hole. In other embodiments, one end of the elastic member 330 and the first limiting portion 314, and the other end of the elastic member 330 and the second limiting portion 322, can also be non-detachably connected. For example, one end of the elastic member 330 and the first limiting portion 314, and the other end of the elastic member 330 and the second limiting portion 322, are connected by welding or riveting.

[0071] Please refer to some embodiments of this application. Figure 9 The second fixing member 320 has a cavity 323 on its side along the first direction. The first fixing member 310 is at least partially inserted into the cavity 323. The first fixing member 310 has a first snap-fit ​​part 315 on its periphery. The cavity 323 has a second snap-fit ​​part 324 on its inner wall. The second snap-fit ​​part 324 and the first snap-fit ​​part 315 can snap into each other.

[0072] Here, the first fixing member 310 is at least partially inserted into the cavity 323. This can be understood as the first fixing member 310 being partially located within the cavity 323 and the other parts of the first fixing member 310 being located outside the cavity 323. With the above arrangement, the first fixing member 310 and the second fixing member 320 are inserted and engaged along the first direction, which can improve the space utilization of the first fixing member 310, making the positioning structure 300 more compact and easier to assemble and disassemble quickly.

[0073] For details, please refer to Figure 9 and Figure 7 The cavity 323 extends along the periphery of the second fixing member 320 in the first direction and has an opening. The first fixing member 310 is inserted into the cavity 323 through the opening to realize the insertion and engagement of the first fixing member 310 and the second fixing member 320.

[0074] In this embodiment, one of the first latching portion 315 and the second latching portion 324 is a buckle, and the other of the first latching portion 315 and the second latching portion 324 is a slot. The slot is rectangular. In other embodiments, the slot may be circular or other shapes.

[0075] For example, please refer to Figure 9 The first fixing member 310 has buckles on both sides, and the cavity wall of the cavity 323 has slots on both sides. When the first fixing member 310 is inserted into the cavity 323, the buckles are engaged in the slots. Since the first fixing member 310 can move relative to the second fixing member 320 in the first direction, the buckles can also move in the first direction in the slots.

[0076] In this embodiment, the number of the first latching portion 315 and the second latching portion 324 is not limited to one. That is, the number of the first latching portion 315 and the second latching portion 324 can both be at least two. All the first latching portions 315 and all the second latching portions 324 can be arranged side by side or in other arrangements.

[0077] Please refer to some embodiments of this application. Figure 10 and Figure 7 The positioning structure also includes a clamping member 400, which is fixed to the second fixing member 320 and has a third shaft hole 401 for the second component 200 to pass through.

[0078] It is understandable that the clamping member 400 is made of rubber, and the second part 200 passes through the third shaft hole 401 of the clamping member 400. Since the compression of the rubber part is fixed, the axial pressure generated by the clamping member 400 on the first part 100 is uniformly fixed, which can prevent the first part 100 from tilting.

[0079] Here, the third shaft hole 401, the second shaft hole 321, and the first shaft hole 313 overlap at least partially in the second direction.

[0080] Please refer to some embodiments of this application. Figure 10 The bottom side of the second fixing member 320 is provided with a first positioning part 325, and a positioning groove is set in the first positioning part 325, and the clamping member 400 is accommodated in the positioning groove.

[0081] In this embodiment, please refer to Figure 1 The second fixing member 320 has two first positioning portions 325 on its bottom side, and the clamping member 400 is accommodated in the two positioning grooves. The clamping member 400 is annular, and the first positioning portions 325 are elongated arc-shaped. In other embodiments, the first positioning portions 325 may also be dot-shaped or other shapes.

[0082] Please refer to some embodiments of this application. Figure 2The first component 100 has a hub in the middle, and a slot 101 is provided on the hub. The bottom side of the second fixing component 320 is provided with a second positioning part 326 that is inserted into the slot 101.

[0083] The above configuration allows the first component 100 to be detachably connected to the second fixing component 320, facilitating assembly and disassembly.

[0084] Here, the center of the hub is also provided with a mounting shaft hole 102 for the second component 200 to pass through.

[0085] In this embodiment, the second positioning part 326 is an elongated arc shape, and correspondingly, the slot 101 is also an arc-shaped hole to fit the second positioning part 326. In other embodiments, the second positioning part 326 may also be a dot shape, and correspondingly, the slot 101 may also be a circular hole.

[0086] In this embodiment, there are two second positioning parts 326, which are arranged opposite to each other. The number and position of the slots 101 and the second positioning parts 326 correspond one-to-one. All the second positioning parts 326 and all the first positioning parts 325 are distributed at intervals around the outer periphery of the second shaft hole 321. In other embodiments, the number of second positioning parts 326 may be at least three, and at least two second positioning parts 326 may be inserted into each slot 101.

[0087] In this embodiment, the second positioning part 326, the first positioning part 325 and the second fixing part 320 are integrally formed structures, which have good integrity and are easy to assemble quickly.

[0088] Please refer to some embodiments of this application. Figure 3 The first fixing member 310 has a first operating position 316 on the side opposite to the second fixing member 320, and the second fixing member 320 has a second operating position 327 on the side opposite to the first fixing member 310. The first operating position 316 and the second operating position 327 are both a number of protrusions evenly distributed along the second direction.

[0089] Specifically, place two fingers on the first operating position 316 and the second operating position 327 respectively, and apply force to the two fingers in opposite directions to compress the elastic member 330, thereby dislodging the limiting part 311 from the limiting groove 201 of the second component 200. Then, remove the positioning structure 300 to complete the disassembly of the positioning structure 300. After disassembly, the first component 100 is no longer fixed and can be removed from the second component 200.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
