Description

Technical Field

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

[0002] To facilitate transportation and storage, fans typically employ a detachable structure. However, the fan's support rod and chassis occupy a significant amount of space when connected, making storage inconvenient. Therefore, enabling the disassembly and assembly of both is crucial.

[0003] In related technologies, most fans have their support rods connected to the chassis via connectors, or the support rods pass through the chassis and are then fixedly connected to the knobs. This involves many installation parts and is quite complex to install and disassemble. Utility Model Content

[0004] Therefore, it is necessary to provide a chassis component and fan that are easy to disassemble and assemble to address the above-mentioned problems.

[0005] A fuselage component, comprising:

[0006] The support rod has a threaded connection at one end along its longitudinal direction; and

[0007] The chassis includes a chassis body and a threaded connection structure. The threaded connection structure is integrally connected to the chassis body and configured to thread with the threaded connection end. The chassis is threadedly connected to the support rod through the threaded connection structure and the threaded connection end.

[0008] In one embodiment, the chassis body has an assembly space, and the chassis also includes a counterweight block disposed within the assembly space.

[0009] In one embodiment, the threaded connection end has an external thread, and the threaded connection structure has an internal thread; the chassis further includes a support rib, which is disposed on the outer surface of the threaded connection structure opposite to the internal thread and supports the chassis body.

[0010] In one embodiment, the threaded connection structure is disposed within the assembly space, and its threaded opening is located on the surface of the chassis body; the counterweight has an assembly hole, and the counterweight is sleeved on the threaded connection structure through the assembly hole.

[0011] In one embodiment, the chassis further includes a threaded post and a threaded component. The threaded post is disposed on the periphery of the threaded connection structure and connects to the threaded connection structure. The counterweight has a through hole that mates with the threaded post. The threaded component mates with the threaded post and fixes the counterweight to the chassis body.

[0012] And / or, the counterweight block is interference-fitted with the supporting rib.

[0013] In one embodiment, the chassis body has at least two snap-fit ​​structures, all of which are used to engage with the counterweight.

[0014] In one embodiment, the support rod and the chassis are configured to rotate relative to each other about a first axis to form a threaded connection;

[0015] The fuselage assembly also includes an anti-rotation member configured to have a switchable locked state and an unlocked state. In the locked state, the anti-rotation member limits the relative rotation of the support rod and the chassis about the first axis. In the unlocked state, the relative rotation of the support rod and the chassis about the first axis is not limited.

[0016] In one embodiment, the anti-rotation member includes an anti-rotation buckle and a locking member, wherein the anti-rotation buckle is anti-rotatingly connected to the support rod on the rotation about the first axis, and the locking member is movably disposed on the support rod;

[0017] The chassis also has a slot, and the anti-rotation buckle is configured to engage and disengage from the slot; at least one of the anti-rotation buckle and the slot has a guide surface, and the guide surface is configured to guide the anti-rotation buckle to disengage from the slot when the support rod and the chassis rotate relative to each other about the first axis.

[0018] The locking member has a locked position and an unlocked position that can be switched by movement. When the locking member is in the locked position, the anti-rotation latch is confined in the slot by the locking member, and the slot limits the anti-rotation latch in its rotation around the first axis. The anti-rotation member is in the locked state. When the locking member is in the unlocked position, the anti-rotation latch is not confined in the slot by the locking member. The anti-rotation member is in the unlocked state.

[0019] In one embodiment, the support rod has a locking groove extending in a direction intersecting the horizontal direction and extending to the side facing the anti-rotation buckle in the snap-in direction. The locking member is disposed in the locking groove and is slidable along the locking groove.

[0020] A fan comprising the aforementioned housing components.

[0021] The aforementioned chassis components and fan utilize a screw-connected support rod to the chassis, with the chassis body and screw connection structure integrated into a single design. This eliminates the need for additional connectors or knobs for securing the chassis, allowing direct connection between the chassis and support rod. This reduces the number of parts in the chassis components, saving costs, and also improves assembly efficiency and ease of disassembly and assembly between the chassis and support rod.

[0040] Please see Figures 1 to 5An embodiment of this application provides a fuselage assembly 100, including a support rod 10 and a chassis 30. One end of the support rod 10 in the longitudinal direction is a threaded connection end 11. The chassis 30 includes a chassis body 31 and a threaded connection structure 32. The threaded connection structure 32 is integrally connected to the chassis body 31 and configured to thread-mate with the threaded connection end 11. The chassis 30 is threadedly connected to the support rod 10 through the threaded connection structure 32 and the threaded connection end 11.

[0041] The housing assembly 100 can be used for a fan, which can be, but is not limited to, a circulating fan. To achieve its normal function, the fan also includes a head assembly, with the support rod 10 having a first end and a second end 13 at its two ends in the longitudinal direction, wherein the first end is a threaded connection end 11 and the second end 13 is used to connect to the head assembly.

[0042] The aforementioned fuselage assembly 100 employs a threaded connection between the support rod 10 and the chassis 30. Furthermore, the chassis body 31 and the threaded connection structure 32 are integrated, eliminating the need for additional connectors or knobs for fixation, allowing the chassis 30 to connect directly to the support rod 10. This reduces the number of parts in the fuselage assembly 100, saving costs, and also improves assembly efficiency and ease of disassembly between the chassis 30 and the support rod 10. In addition, the chassis 30 and the support rod 10 do not require connection through other accessories, resulting in a more stable connection and less wobbling.

[0043] Please refer to the following: Figure 6 and Figure 7 In some embodiments, the chassis body 31 has an assembly space 311, and the chassis 30 also includes a counterweight 33, which is disposed in the assembly space 311.

[0044] Thus, the counterweight 33, installed inside the chassis body 31, lowers the center of gravity of the fuselage component 100, helping to improve its stability. On the other hand, the counterweight 33 also enhances the structural strength of the chassis body 31, making the chassis 30 as a whole stronger.

[0045] In some embodiments, the threaded connection end 11 has an external thread, and the threaded connection structure 32 has an internal thread. The chassis 30 also includes a support rib 34, which is disposed on the outer surface of the threaded connection structure 32 facing away from the internal thread and supports the chassis body 31.

[0046] Understandably, the side of the threaded connection structure 32 with the internal thread is the inner side, and the side opposite to this side is the outer side. One side of the support rib 34 is connected to the outer surface of the threaded connection structure 32, and the other side is connected to the chassis body 31. In addition, the support rib 34 can be integrally connected to the threaded connection structure 32 and the chassis body 31.

[0047] Thus, the support rib 34 can support the threaded connection structure 32, which helps to increase the strength of the threaded connection structure 32 and thereby improve the stability of the connection between the chassis 30 and the support rod 10.

[0048] In some embodiments, the threaded connection structure 32 is disposed within the assembly space 311, and its threaded opening is located on the surface of the chassis body 31. The counterweight 33 has an assembly hole 331, and the counterweight 33 is sleeved on the threaded connection structure 32 through the assembly hole 331.

[0049] Understandably, the support rod 10 is located above the chassis 30, and the threaded opening is located on the bottom surface of the chassis body 31, specifically at the center of the chassis 30. In particular, the chassis body 31 can be generally circular, and the threaded connection structure 32 is located at the center of the chassis body 31.

[0050] Thus, the threaded connection structure 32 is located inside the chassis body 31, which helps reduce the space required for the chassis 30 after disassembly and facilitates storage. At the same time, the chassis body 31 can also protect the threaded connection structure 32 located inside it. The counterweight 33 can be set around the threaded connection structure 32. It cooperates with the threaded connection structure 32 through the mounting hole 331. The threaded connection structure 32 can be used to position the counterweight 33, and the counterweight 33 surrounds the periphery of the threaded connection structure 32 to strengthen the protection of the threaded connection structure 32.

[0051] Furthermore, the chassis 30 also includes a threaded post 35 and a threaded component 36. The threaded post 35 is located on the periphery of the threaded connection structure 32 and connects to the threaded connection structure 32. The counterweight 33 has a through hole 333 that mates with the threaded post 35. The threaded component 36 mates with the threaded post 35 and fixes the counterweight 33 to the chassis body 31.

[0052] One end of the threaded post 35 can be connected to the chassis body 31, and the side is connected to the threaded connection structure 32. The number of threaded posts 35 can be at least two. Understandably, the through hole 333 communicates with the assembly hole 331 so that the structure connecting the threaded post 35 and the threaded connection structure 32 can pass through.

[0053] Thus, the threaded column 35 and the threaded component 36 cooperate to fix the counterweight 33 to the chassis body 31. At the same time, the threaded main connection threaded connection structure 32 can support it and improve its structural strength.

[0054] Furthermore, the counterweight 33 and the supporting rib 34 are interference-fitted.

[0055] In this way, the counterweight 33 can effectively support the threaded connection structure 32 through its mounting hole 331, enhance the stability of the threaded connection structure 32, and avoid large shaking of the whole machine.

[0056] Understandably, in some other embodiments, the threaded connection end 11 has an internal thread, and the threaded connection structure 32 has an external thread. Accordingly, the support rib 34 may be provided on the inner surface of the threaded connection structure 32 facing away from the external thread and supported on the chassis body 31. Accordingly, the threaded connection structure 32 may be located outside the assembly space 311 and protrude from the top surface of the chassis body 31, without specific limitations.

[0057] In some embodiments, the chassis body 31 has at least two snap-fit ​​structures 313, all of which are used to engage with the counterweight 33.

[0058] Understandably, the snap-fit ​​structure 313 engages with the counterweight 33 after it is installed into the assembly space 311, thereby limiting its movement to prevent it from detaching from the chassis body 31.

[0059] In this way, the buckle structure 313 can effectively fix the counterweight 33 around its perimeter, preventing the chassis body 31 from deforming and detaching from the counterweight 33, thus affecting the overall appearance of the machine.

[0060] In some embodiments, the chassis body 31 further has a mounting boss 37, which is located at one end of the threaded connection structure 32 that connects to the chassis body 31 and protrudes radially along the threaded connection structure 32. The counterweight 33 has a mounting groove 335 that mates with the mounting boss 37.

[0061] Thus, the fit between the mounting boss 37 and the mounting groove 335 can effectively improve the accuracy of the assembly between the counterweight 33 and the chassis body 31, and reduce the probability of them moving around each other.

[0062] Please refer to the following: Figures 8 to 10 In some embodiments, the support rod 10 and the chassis 30 are configured to rotate relative to each other about a first axis to form a threaded connection. The body assembly 100 also includes an anti-rotation member 50, which is configured to have a switchable locked state and an unlocked state. In the locked state, the anti-rotation member 50 limits the relative rotation of the support rod 10 and the chassis 30 about the first axis. In the unlocked state, the relative rotation of the support rod 10 and the chassis 30 about the first axis is not limited.

[0063] Understandably, when the anti-rotation element 50 is in the locked state, the support rod 10 and the chassis 30 are limited by the anti-rotation element 50 and cannot rotate relative to each other, that is, the two cannot be threadedly separated. When the anti-rotation element 50 is in the unlocked state, the support rod 10 and the chassis 30 are not limited by the anti-rotation element 50, that is, the two can rotate relative to each other and be threadedly separated.

[0064] Thus, after the support rod 10 and the chassis 30 are assembled, they can be locked together by the anti-rotation component 50, preventing them from rotating relative to each other. This reduces the probability of loosening of the threaded connection due to factors such as high-frequency vibration, and improves the stability of the threaded connection. When it is necessary to separate the support rod 10 and the chassis 30, simply switch the anti-rotation component 50 to the unlocked state, and the user can rotate the support rod 10 and the chassis 30 normally to separate them.

[0065] Furthermore, the anti-rotation component 50 includes an anti-rotation buckle 51 and a locking component 53. The anti-rotation buckle 51 is connected to the support rod 10 to prevent rotation on the rotation around the first axis, and the locking component 53 is movably disposed on the support rod 10.

[0066] The chassis 30 also has a slot 38, and the anti-rotation latch 51 is configured to engage and disengage from the slot 38. At least one of the anti-rotation latch 51 and the slot 38 has a guide surface, which is configured to guide the anti-rotation latch 51 out of the slot 38 when the support rod 10 and the chassis 30 rotate relative to each other about the first axis.

[0067] The locking member 53 has a locked position and an unlocked position that can be switched by movement. When the locking member 53 is in the locked position, the anti-rotation latch 51 is confined within the slot 38 by the locking member 53, and the slot 38 limits the rotation of the anti-rotation latch 51 around the first axis, so the anti-rotation member 50 is in the locked state. When the locking member 53 is in the unlocked position, the anti-rotation latch 51 is not confined within the slot 38 by the locking member 53, so the anti-rotation member 50 is in the unlocked state.

[0068] The anti-rotation latch 51 prevents the support rod 10 from rotating during rotation around the first axis. Therefore, during rotation around the first axis, the anti-rotation latch 51 and the support rod 10 operate synchronously, either rotating together or both stopping their rotation. They can form an anti-rotation connection through an anti-rotation fitting structure, such as the anti-rotation latch 51 having an anti-rotation protrusion extending along the direction of the first axis, and the support rod 10 having an anti-rotation groove that mates with the anti-rotation protrusion. Alternatively, the anti-rotation latch 51 can also be fixedly connected to the support rod 10.

[0069] After the support rod 10 and the chassis 30 are connected by threads, the position of the anti-rotation latch 51 in the direction of the first axis corresponds to the position of the slot 38. The anti-rotation latch 51 can engage with the slot 38 of the chassis 30. The engagement of the anti-rotation latch 51 with the slot 38 means that the latching part 517 engages with the slot 38, forming an engaging relationship with the slot 38. Correspondingly, the disengagement of the anti-rotation latch 51 from the slot 38 means that the latching part 517 disengages from the slot 38, releasing the engaging relationship with the slot 38.

[0070] When the locking member 53 is in the locked position, it confines the locking member 53 within the slot 38 and prevents it from disengaging from the slot 38. The slot 38 provides a directional limit on the locking member 53 around the first axis, preventing it from rotating relative to the chassis 30. In other words, the anti-rotation latch 51 is engaged within the slot 38 and cannot disengage, thus preventing it from rotating around the first axis. Correspondingly, the support rod 10, which is anti-rotatingly connected to the anti-rotation latch 51, is also unable to rotate relative to the chassis 30.

[0071] When the locking member 53 is in the unlocked position, when the drive support rod 10 and the chassis 30 rotate relative to each other around the first axis, the anti-rotation buckle 51 can disengage from the slot 38 under the guidance of the guide surface, and therefore will not limit the relative rotation of the support rod 10 and the chassis 30 around the first axis.

[0072] Thus, the locking member 53 can be driven to move between the locked position and the unlocked position, switching the state of the anti-rotation member 50. The anti-rotation latch 51 can be engaged in the latch groove 38, and after the locking member 53 moves to the locked position, it can limit the anti-rotation latch 51 in the latch groove 17, so that the anti-rotation member 50 limits the relative rotation of the support rod 10 and the chassis 30 around the first axis.

[0073] In some embodiments, the chassis 30 has a plurality of slots 38, all of which are continuously arranged around a first axis.

[0074] Specifically, the chassis 30 has a series of internal teeth 39 arranged continuously at the outer edge of the pipe opening. All the internal teeth 39 are arranged around the inner circumference of the entire chassis 30, and a groove 38 is formed between the internal teeth 39.

[0075] In this way, the support rod 10 and the chassis 30 can rotate continuously, and when stopped at any position, the anti-rotation buckle 51 can be engaged into the adjacent slot 38, and then locked by the locking member 53.

[0076] In some embodiments, the support rod 10 is rotatable relative to the chassis 30 in a first direction and is threadedly connected to the chassis 30. The support rod 10 is also rotatable relative to the chassis 30 in a second direction and is threadedly disengaged from the chassis 30. An anti-rotation latch 51 engages with a slot 38 in an engaging direction. The anti-rotation latch 51 has a first guide surface 511 and a second guide surface 513, both intersecting the engaging direction. The first guide surface 511 is configured to guide the anti-rotation latch 51 out of the slot 38 when the support rod 10 rotates relative to the chassis 30 in the first direction, and the second guide surface 513 is configured to guide the anti-rotation latch 51 out of the slot 38 when the support rod 10 rotates relative to the chassis 30 in the second direction. Alternatively, the slot 38 has a third guide surface 381 and a fourth guide surface 383, both of which intersect the insertion direction. The third guide surface 381 is configured to guide the anti-rotation latch 51 out of the slot 38 when the support rod 10 rotates relative to the chassis 30 in a first direction. The fourth guide surface 383 is configured to guide the anti-rotation latch 51 out of the slot 38 when the support rod 10 rotates relative to the chassis 30 in a second direction.

[0077] Understandably, the third guide surface 381 and the fourth guide surface 383 serve as the two walls of the slot 38, which are also the two tooth surfaces of the internal tooth 39.

[0078] Thus, when the locking element 53 is in the unlocked position, the user drives the support rod 10 to rotate relative to the chassis 30. After the anti-rotation buckle 51 is inserted into the slot 38, it can smoothly and continuously disengage from the slot 38 under the guidance of the first guide surface 511 and the second guide surface 513 and / or the third guide surface 381 and the fourth guide surface 383, without getting stuck in the slot 38 and preventing the support rod 10 from rotating relative to the chassis 30, so that the user can connect and disconnect the support rod 10 from the chassis 30.

[0079] Furthermore, when the locking member 53 is in the locked position, it abuts against the back side of the anti-rotation latch 51 in the insertion direction.

[0080] Understandably, when the locking member 53 is switched to the unlocked position, it leaves the back of the anti-rotation latch 51. The engaging direction can be, but is not limited to, a radial direction extending outward from the first rotating shaft, and the groove depth direction of the slot 38 is the radial direction extending outward from the first rotating shaft.

[0081] Thus, after the anti-rotation latch 51 is engaged in the slot 38 in the engagement direction, the locking member 53 can move to the back of the anti-rotation latch 51 and abut against the anti-rotation latch 51 to prevent it from disengaging from the slot 38, thereby achieving the effect of confining it within the slot 38.

[0082] Furthermore, the support rod 10 has a locking groove 15, the extension direction of which intersects with the horizontal direction and extends to the back of the anti-rotation buckle 51 facing upward in the insertion direction. The locking member 53 is disposed in the locking groove 15 and can slide in the locking groove along the extension direction of the locking groove 15 to switch between the locked position and the unlocked position.

[0083] Specifically, the locking member 53 moves to the two ends of the locking slide 15, which are respectively in the locked position and the unlocked position. The lower end of the locking slide 15 in the direction of gravity corresponds to the locked position, and the top end corresponds to the unlocked position.

[0084] Thus, the extension direction of the locking groove 15 intersects the horizontal direction. In the normal operating state of the body assembly 100, the support rod 10 is positioned above and the chassis 30 below. The locking element 53 can be stably locked under gravity, preventing the threads from loosening. When the user needs to disassemble the chassis 30, simply invert the body assembly 100, allowing the locking element 53 to move to the unlocked position under gravity. The operation is convenient and the locking is reliable.

[0085] In some embodiments, the anti-rotation buckle 51 includes a connected connecting arm 515 and a buckle portion 517. The connecting arm 515 is configured to undergo elastic deformation, and the buckle portion 517 is disposed on the connecting arm 515 and can be driven into the buckle slot 38 by the connecting arm 515.

[0086] The snapping direction of the anti-rotation buckle 51 is the moving direction of the buckle part 517 when it snaps into the slot 38. The anti-rotation buckle 51 enables the buckle part 517 to move between snapping into and disengaging from the slot 38 through the deformation of the connecting arm 515, and the connecting arm 515 is configured to provide the driving force for the buckle part 517 to snap into the slot 38.

[0087] Specifically, when the locking member 53 is in the locked position, it confines the latching part 517 within the latching groove 38. In the latching direction, the latching part 517 is located at the front of the connecting arm 515, and when the locking member 53 is in the locked position, it abuts against the back of the connecting arm 515.

[0088] Thus, the latching part 517 can also be latched into the slot 38 under the drive of the connecting arm 515. At the same time, under the guidance of the guide surface, the latching part 517 can overcome the driving force of the connecting arm 515 by squeezing it, causing it to deform and disengage from the slot 38.

[0089] In some embodiments, the anti-rotation member 50 further includes an anti-rotation ring 55, which is sleeved on the support rod 10 and engages with the support rod 10 to prevent rotation in the direction of rotation about the first axis. The anti-rotation ring 55 has a movable opening 551, one end of the connecting arm 515 is connected to the edge of the movable opening 551, and the other end is movably located within the movable opening 551.

[0090] Understandably, one end of the connecting arm 515 is the connecting end, which is connected to the edge of the movable opening 551 of the anti-rotation ring 55, and the other end is the free end, so that the connecting arm 515 can undergo elastic deformation within the movable opening 551.

[0091] Specifically, the anti-rotation ring 55 has an anti-rotation protrusion, and the support rod 10 has an anti-rotation groove. The two are connected to prevent rotation by the cooperation of the anti-rotation protrusion and the anti-rotation groove.

[0092] Thus, the latching part 517 can move along with the connecting arm 515 within the movable opening 551.

[0093] In some embodiments, the support rod 10 further has a latching groove 17, which is located on the back side of the anti-rotation latch 51 in the snapping direction.

[0094] Understandably, the size of the latching groove 17 is larger than that of the anti-rotation latch 51. The latching groove 17 provides clearance for the anti-rotation latch 51, so that when the anti-rotation latch 51 disengages from the latching groove 38, it at least partially enters the latching groove 17. At the same time, the locking slide 15 is connected to the latching groove 17 so that the locking member 53 can move to abut against the back of the anti-rotation latch 51.

[0095] Thus, the latching slot 17 provides room for the anti-rotation latch 51 to move during the process of engaging and disengaging from the latching slot 38.

[0096] The aforementioned fuselage assembly 100 has a support rod 10 with one end designed as a threaded connection end 11, and the other end for connection to the machine head. The threaded connection end 11 mates with a threaded connection structure 32 located at the center of the chassis 30 to achieve a threaded connection. Ribs 34 are provided on the back of the threaded connection structure 32 of the chassis 30, which help increase the strength of the threaded connection structure 32. Screw posts are also provided around the threaded connection structure 32; one or more screw posts can be designed. The counterweight block 33 has an assembly hole 331 through which the threaded connection structure 32 passes, and also a through hole 333 through which the screw posts pass.

[0097] After assembly, the screw posts on the chassis body 31 pass through the through holes 333 of the counterweight block 33 and are fixed by the threaded parts 36, thus fixing the chassis body 31 and the counterweight block 33. The supporting ribs 34 and the mounting holes 331 of the counterweight block 33 are either interference-fitted or have a small clearance fit. After assembly, the counterweight block 33 can effectively support the threaded connection structure 32 through its mounting holes 331, enhancing the stability of the threaded connection structure 32 and preventing excessive shaking of the entire machine. The chassis body 31 also has multiple (three or more) snap-fit ​​structures 313 around its perimeter, which cooperate with the counterweight block 33. After assembly, the snap-fit ​​structures 313 can effectively fix the counterweight block 33 around its perimeter, preventing the chassis body 31 from deforming and detaching from the counterweight block 33, thus affecting the overall appearance of the machine.

[0098] Thus, the body assembly 100 adopts a scheme where the support rod 10 is threadedly connected to the chassis 30, and the chassis body 31 and the threaded connection structure 32 are integrated into one design. The counterweight 33 is directly fixed to the chassis body 31, eliminating the need for additional joints or knobs for fixation, reducing the number of parts, saving costs, and improving assembly efficiency. The threaded connection structure 32 and the counterweight 33 fit tightly together, so that the counterweight 33 can provide auxiliary support for the threaded connection structure 32, preventing insufficient strength of the threaded connection structure 32, improving the stability of the threaded connection structure 32, and reducing the shaking of the entire machine.

[0099] Furthermore, during normal use, the body assembly 100 is upright, with the support rod 10 on top and the chassis 30 on the bottom. The locking member 53 abuts against the anti-rotation latch 51, preventing it from deforming and locking it in the slot 38. The support rod 10 and chassis 30 cannot be threaded apart. At this time, the support rod 10 and chassis 30 are stably connected and less affected by external factors such as vibration. Similarly, when it is necessary to remove the chassis 30, simply invert the body assembly 100, allowing the locking member 53 to move away from behind the anti-rotation latch 51. By twisting it forcefully, the anti-rotation latch 51 will deform and retract under the guidance of the guide surface, making it easy to unscrew the support rod 10 and chassis 30.

[0100] This application also provides a fan, including the connection structure described above, and the fan can be, but is not limited to, a circulation fan.
