Description

Technical Field

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

[0002] To facilitate transportation and storage, fans are usually designed to be detachable. When connected, the fan's support rod and chassis occupy a large amount of space, making them inconvenient to store. Therefore, it is particularly important to be able to detach and assemble the two.

[0003] In the related art, the support rods of most fans are connected to the chassis through a joint, or the support rods pass through the chassis and are then fixedly connected to the knob, which requires many installation parts and is relatively complicated to assemble and disassemble. Summary of the Invention

[0007] The chassis includes a chassis body and a threaded connection structure. The threaded connection structure is integrally connected to the chassis body and is configured to be threadably matched 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 therein, and the chassis further includes a counterweight block, and the counterweight block is arranged in the assembly space.

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

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

[0021] The chassis assembly and fan utilize a threaded connection between the support rod and chassis. The chassis body and threaded connection structure are integrated into the chassis, eliminating the need for additional connectors or knobs for fastening. This reduces the number of parts in the chassis assembly, saving costs. The assembly between the chassis and support rod is also more efficient and easier to assemble and disassemble.

[0040] Referring to Figures 1 to 5 , a fuselage assembly 100 provided in one embodiment of the present application includes 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 is configured to threadably engage with the threaded connection end 11. The chassis 30 is threadedly connected to the support rod 10 via the threaded connection structure 32 and the threaded connection end 11.

[0041] The body 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. The support rod 10 has two ends in the longitudinal direction, namely a first end and a second end 13. 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 utilizes a threaded connection between the support rod 10 and the chassis 30. The chassis body 31 and the threaded connection structure 32 are integrated into one design, eliminating the need for additional joints or knobs for fastening, allowing the chassis 30 to be directly connected to the support rod 10. This reduces the number of parts, saving costs, and also improves assembly and disassembly efficiency between the chassis 30 and the support rod 10. Furthermore, since the chassis 30 and the support rod 10 do not require additional components for connection, the connection between them is more stable and less wobbly.

[0043] Please refer to FIG. 6 and FIG. 7 . In some embodiments, the chassis body 31 has an assembly space 311 therein. The chassis 30 further includes a counterweight 33 . The counterweight 33 is disposed in the assembly space 311 .

[0044] Thus, the counterweight 33 is assembled in the chassis body 31, which can move the center of gravity of the fuselage assembly 100 downward, thereby improving its stability. On the other hand, the counterweight 33 can also enhance the structural strength of the chassis body 31, making the overall strength of the chassis 30 higher.

[0045] In some embodiments, the threaded connection end 11 has external threads, and the threaded connection structure 32 has internal threads. The chassis 30 further includes support ribs 34 , which are disposed on the outer surface of the threaded connection structure 32 facing away from the internal threads and supported by the chassis body 31 .

[0046] It can be understood that the side of the threaded connection structure 32 where the internal threads are formed is the inner side, and the side opposite to the inner side is the outer side. The support rib 34 is connected to the outer surface of the threaded connection structure 32 on one side and to the chassis body 31 on the other side. In addition, the support rib 34 can be integrally connected to the threaded connection structure 32 and the chassis body 31.

[0047] In this way, the supporting ribs 34 can support the threaded connection structure 32 , which is beneficial to increase the strength of the threaded connection structure 32 , thereby improving 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 in 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 , through which the counterweight 33 is sleeved on the threaded connection structure 32 .

[0049] It can be understood that the support rod 10 is provided above the chassis 30, and the threaded opening is located on the bottom surface of the chassis body 31, and specifically can be located at the center of the chassis 30. Specifically, the chassis body 31 can be substantially circular, and the threaded connection structure 32 is provided at the center of the chassis body 31.

[0050] The threaded connection structure 32 is located within the chassis body 31, reducing the space required by the disassembled chassis 30 and facilitating storage. Furthermore, the chassis body 31 protects the threaded connection structure 32 within it. The counterweight 33 is centered around the threaded connection structure 32, mating with the threaded connection structure 32 via the assembly hole 331. The threaded connection structure 32 allows for positioning of the counterweight 33, which is then surrounded by the counterweight 33, providing enhanced protection for the threaded connection structure 32.

[0051] Furthermore, the chassis 30 includes a threaded post 35 and a threaded member 36. The threaded post 35 is provided around the threaded connection structure 32 and is connected to the threaded connection structure 32. The counterweight 33 has a through hole 333 that cooperates with the threaded post 35. The threaded member 36 cooperates with the threaded post 35 and fixes the counterweight 33 to the chassis body 31.

[0052] One end of the threaded column 35 can be connected to the chassis body 31, and the side surface is connected to the threaded connection structure 32, and the number of threaded columns 35 can be at least two. It can be understood that the through hole 333 is connected to the assembly hole 331 so that the structure connected to the threaded column 35 and the threaded connection structure 32 can pass through.

[0053] In this way, the threaded column 35 and the threaded member 36 cooperate to fix the counterweight 33 to the chassis body 31. At the same time, the main threaded 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 fit.

[0055] In this way, the counterweight 33 can effectively support the threaded connection structure 32 through its assembly hole 331, thereby enhancing the stability of the threaded connection structure 32 and preventing the entire device from shaking significantly.

[0056] It is understood that in other embodiments, the threaded connection end 11 has internal threads and the threaded connection structure 32 has external threads. Accordingly, the support rib 34 can be provided on the inner surface of the threaded connection structure 32 facing away from the external threads and supported by the chassis body 31. Accordingly, the threaded connection structure 32 can be located outside the assembly space 311 and protrude from the top surface of the chassis body 31, which is not specifically limited here.

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

[0058] It can be understood that the snap structure 313 engages with the counterweight 33 after the counterweight 33 is installed in the assembly space 311 to limit the counterweight 33 and prevent it from being separated from the chassis body 31 .

[0059] In this way, the buckle structure 313 can effectively fix the four sides of the counterweight 33 to prevent the chassis body 31 from deforming and separating from the counterweight 33, thereby affecting the appearance of the entire machine.

[0060] In some embodiments, the chassis body 31 also has an assembly boss 37, which is located at one end of the threaded connection structure 32 connected to the chassis body 31 and is arranged to protrude radially along the threaded connection structure 32. The counterweight block 33 has an assembly groove 335 that cooperates with the assembly boss 37.

[0061] In this way, the cooperation formed by the assembly boss 37 and the assembly groove 335 can effectively improve the assembly accuracy between the counterweight block 33 and the chassis body 31 and reduce the probability of mutual movement between the two.

[0062] Referring to 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 fuselage assembly 100 further includes a rotation stop 50 , which is configured to have a switchable locked state and an unlocked state. In the locked state, the rotation stop 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] It is understood that when the stopper 50 is in the locked state, the support rod 10 and the chassis 30 are limited by the stopper 50 and cannot rotate relative to each other, that is, the two cannot be threadedly separated. When the stopper 50 is in the unlocked state, the support rod 10 and the chassis 30 are not limited by the stopper 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, the anti-rotation member 50 can be used to lock the two, preventing them from rotating relative to each other, thereby reducing the possibility of loosening of the threaded connection due to factors such as high-frequency vibration and improving the stability of the threaded connection. When it is necessary to separate the support rod 10 and the chassis 30, the anti-rotation member 50 can be switched 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 member 50 includes an anti-rotation buckle 51 and a locking member 53 . The anti-rotation buckle 51 is connected to the support rod 10 to prevent rotation around the first axis, and the locking member 53 is movably provided on the support rod 10 .

[0066] The chassis 30 further comprises a slot 38, and the anti-rotation buckle 51 is configured to be inserted into and removed from the slot 38. At least one of the anti-rotation buckle 51 and the slot 38 comprises a guide surface, which is configured to guide the anti-rotation buckle 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 buckle 51 is restrained by the locking member 53 within the retaining groove 38. The retaining groove 38 limits the rotation of the anti-rotation buckle 51 about the first axis, and the anti-rotation member 50 is in a locked state. When the locking member 53 is in the unlocked position, the anti-rotation buckle 51 is not restrained by the locking member 53 within the retaining groove 38, and the anti-rotation member 50 is in an unlocked state.

[0068] The anti-rotation buckle 51 is connected to the support rod 10 to prevent rotation about the first axis. Therefore, when rotating about the first axis, the anti-rotation buckle 51 and the support rod 10 operate synchronously, rotating or preventing rotation together. The two can be connected by a rotation-proof mating structure, for example, the anti-rotation buckle 51 includes a rotation-proof protrusion extending along the first axis, and the support rod 10 includes a rotation-proof groove that cooperates with the rotation-proof protrusion. Alternatively, the anti-rotation buckle 51 can be fixedly connected to the support rod 10.

[0069] After the support rod 10 and the chassis 30 are threadedly connected, the position of the anti-rotation buckle 51 in the direction of the first axis corresponds to the position of the slot 38. The anti-rotation buckle 51 can be snapped into the slot 38 of the chassis 30. The snapping of the anti-rotation buckle 51 into the slot 38 means that the snap portion 517 snaps into the slot 38, forming an engagement relationship with the slot 38. Correspondingly, the snapping of the anti-rotation buckle 51 out of the slot 38 means that the snap portion 517 snaps out of the slot 38, releasing the engagement relationship with the slot 38.

[0070] When the locking member 53 is in the locked position, it is trapped in the slot 38 and cannot be disengaged from the slot 38. The slot 38 can limit the locking member 53 in rotation about the first axis, preventing it from rotating relative to the chassis 30. In other words, the anti-rotation buckle 51 is engaged in the slot 38 and cannot be disengaged, thereby preventing it from rotating about the first axis. Accordingly, the support rod 10, which is anti-rotationally connected to the anti-rotation buckle 51, is also unable to rotate relative to the chassis 30.

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

[0072] In this way, 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 buckle 51 can be engaged with the locking groove 38, and after the locking member 53 moves to the locked position, it can restrain the anti-rotation buckle 51 in the buckle groove 17, so that the anti-rotation member 50 limits the relative rotation of the support rod 10 and the chassis 30 about the first axis.

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

[0074] Specifically, the chassis 30 is formed with a plurality of continuously arranged inner teeth 39 at the outer edge of the pipe mouth. All the inner teeth 39 are arranged around the inner circumference of the entire chassis 30 , and slots 38 are formed between the inner 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 locked into the adjacent slot 38 and then locked by the locking member 53.

[0076] In some embodiments, the support rod 10 can be threadedly connected to the chassis 30 by rotating along a first direction relative to the chassis 30. The support rod 10 can also be threadedly separated from the chassis 30 by rotating along a second direction relative to the chassis 30. The anti-rotation buckle 51 is snapped into the card slot 38 along the snap-in direction. The anti-rotation buckle 51 has a first guide surface 511 and a second guide surface 513, and the first guide surface 511 and the second guide surface 513 both intersect with the snap-in direction. The first guide surface 511 is configured to generate a guide to guide the anti-rotation buckle 51 out of the card slot 38 when the support rod 10 is rotated along the first direction relative to the chassis 30, and the second guide surface 513 is configured to generate a guide to guide the anti-rotation buckle 51 out of the card slot 38 when the support rod 10 is rotated along the second direction relative to the chassis 30; and / Or, the slot 38 has a third guide surface 381 and a fourth guide surface 383, and the third guide surface 381 and the fourth guide surface 383 both intersect with the insertion direction. The third guide surface 381 is configured to guide the anti-rotation buckle 51 to disengage from the slot 38 when the support rod 10 rotates along the first direction relative to the chassis 30, and the fourth guide surface 383 is configured to guide the anti-rotation buckle 51 to disengage from the slot 38 when the support rod 10 rotates along the second direction relative to the chassis 30.

[0077] It can be understood that the third guide surface 381 and the fourth guide surface 383 serve as two wall surfaces of the slot 38 , that is, two tooth surfaces of the inner teeth 39 .

[0078] In this way, when the locking piece 53 is in the unlocked position, the user drives the support rod 10 and the chassis 30 to rotate relative to each other. After being inserted into the slot 38, the anti-rotation buckle 51 can be smoothly and continuously disengaged 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, and will not be stuck in the slot 38 to prevent the support rod 10 and the chassis 30 from rotating relative to each other, so that the user can disconnect the support rod 10 and the chassis 30.

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

[0080] It can be understood that when the locking member 53 is switched to the unlocked position, it leaves the back of the anti-rotation buckle 51. The locking 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 locking groove 38 is the radial direction extending outward from the first rotating shaft.

[0081] In this way, after the anti-rotation buckle 51 is inserted into the slot 38 along the insertion direction, the locking piece 53 can move to the back of the anti-rotation buckle 51 and press against the anti-rotation buckle 51 to prevent it from escaping from the slot 38, thereby achieving the effect of limiting it in the slot 38.

[0082] Furthermore, the support rod 10 has a locking groove 15, the extension direction of the locking groove 15 intersects with the horizontal direction, and extends to the back side of the stop buckle 51 in the locking direction. The locking piece 53 is arranged 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 slot 15 and corresponds to the locking position and the unlocking position respectively, wherein the lower end of the locking slot 15 in the gravity direction corresponds to the locking position, and the top end corresponds to the unlocking position.

[0084] Thus, the extension direction of the locking slot 15 intersects the horizontal direction. When the body assembly 100 is in normal use, with the support rod 10 at the top and the chassis 30 at the bottom, the locking member 53 can be stably locked in the locked position under the action of gravity, preventing the threads from loosening. To remove the chassis 30, the user simply inverts the body assembly 100, causing the locking member 53 to shift to the unlocked position under the action of gravity. This is convenient and secure.

[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 be able to undergo elastic deformation. The buckle portion 517 is provided on the connecting arm 515 and can be driven into the slot 38 when the connecting arm 515 is driven.

[0086] The locking direction of the anti-rotation buckle 51 is the moving direction of the buckle part 517 when it is locked into the slot 38. The anti-rotation buckle 51 enables the buckle part 517 to move between locking in and disengaging from the slot 38 through the deformation of the connecting arm 515, and the connecting arm 515 is configured to provide a driving force to drive the buckle part 517 to lock into the slot 38.

[0087] Specifically, when the locking member 53 is in the locked position, the buckle portion 517 is restricted in the slot 38. In the snap-in direction, the buckle portion 517 is located in 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] In this way, the buckle portion 517 can also be locked into the slot 38 under the drive of the connecting arm 515. At the same time, under the guidance of the guide surface, the buckle portion 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 about the first axis. The anti-rotation ring 55 has a movable opening 551, and 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] It can be understood that one end of the connecting arm 515 is a connecting end connected to the edge of the movable opening 551 of the stop ring 55 , and the other end is a free end, so that the connecting arm 515 can undergo elastic deformation in the movable opening 551 .

[0091] Specifically, a rotation-stopping protrusion is constructed on the rotation-stopping ring 55, and a rotation-stopping groove is constructed on the support rod 10. The two are connected to each other through the cooperation of the rotation-stopping protrusion and the rotation-stopping groove.

[0092] In this way, the locking portion 517 can move along with the movement of the connecting arm 515 in the movable opening 551 .

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

[0094] It can be understood that the buckle groove 17 is larger than the anti-rotation buckle 51, and the buckle groove 17 provides a clearance for the anti-rotation buckle 51. When the anti-rotation buckle 51 is released from the locking groove 38, it at least partially enters the buckle groove 17. At the same time, the locking groove 15 is connected to the buckle groove 17, so that the locking member 53 can move to abut against the back of the anti-rotation buckle 51.

[0095] In this way, the buckle groove 17 can provide a movable space for the anti-rotation buckle 51 so that it can move in the process of being inserted into and released from the buckle groove 38 .

[0096] In the aforementioned fuselage assembly 100, one end of the support rod 10 is designed as a threaded connection end 11, and the other end is used to connect to the machine head. The threaded connection end 11 cooperates with the threaded connection structure 32 located in the center of the chassis 30 to achieve a threaded connection. Ribs are provided on the back of the threaded connection structure 32 of the chassis 30, and the supporting ribs 34 help to increase the strength of the threaded connection structure 32. Screw columns are also provided around the threaded connection structure 32, and the number of screw columns can be one or more. The counterweight block 33 has an assembly hole 331 in the center for the threaded connection structure 32 to pass through, as well as a through hole 333 for the screw column to pass through.

[0097] After assembly, the screw column on the chassis body 31 passes through the through hole 333 of the counterweight block 33 and is fixed by the screw member 36. The chassis body 31 and the counterweight block 33 are fixed. The supporting rib 34 and the assembly hole 331 of the counterweight block 33 have an interference fit or a small clearance fit. After assembly, the counterweight block 33 can effectively support the threaded connection structure 32 through its assembly hole 331, strengthen the stability of the threaded connection structure 32, and prevent the whole machine from shaking too much. There are also multiple (3 or more) snap structures 313 around the chassis body 31, and the snap structures 313 cooperate with the counterweight block 33. After assembly, the snap structures 313 can effectively fix the counterweight block 33 on all sides, preventing the chassis body 31 from deforming and detaching from the counterweight block 33, which would affect the appearance of the whole machine.

[0098] Thus, the fuselage assembly 100 utilizes a threaded connection between the support rod 10 and the chassis 30, and the chassis body 31 and the threaded connection structure 32 are integrated into a single design. The counterweight 33 is directly fixed to the chassis body 31, eliminating the need for additional joints or knobs for fastening. This reduces the number of parts, saves costs, and improves assembly efficiency. The threaded connection structure 32 and the counterweight 33 closely mate, allowing the counterweight 33 to provide auxiliary support for the threaded connection structure 32, preventing the threaded connection structure 32 from being insufficiently strong, 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 positioned at the top and the chassis 30 positioned at the bottom. The locking member 53 abuts against the anti-rotation buckle 51, preventing it from deforming and becoming stuck in the slot 38. This prevents the support rod 10 from being threadedly separated from the chassis 30. In this state, the support rod 10 and chassis 30 are stably connected, less susceptible to external interference such as vibration. Similarly, to remove the chassis 30, simply invert the body assembly 100, move the locking member 53 away from the anti-rotation buckle 51, and twist firmly. The anti-rotation buckle 51, guided by the guide surface, will deform and move backward, allowing the support rod 10 and chassis 30 to be easily unscrewed.

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