Machine body assembly and fan

Abstract

The invention relates to a machine body assembly and a fan. The machine body assembly comprises a machine body rod, a support and a locking mechanism. The support is rotationally connected with the fuselage rod and has an unfolding position and a folding position. The support rotates relative to the fuselage rod and is switched between the unfolding position and the folding position. The locking mechanism is arranged on the machine body rod and comprises a blocking piece. The blocking piece is movably arranged and is configured to move to block the support from rotating towards the folding position when the support is located at the unfolding position. According to the machine body assembly, the machine body assembly is locked in the mode that rotation of the support is blocked through the blocking piece. In the process, the blocking piece does not need to have the elastic deformation capacity. Therefore, the blocking piece can have enough strength to prevent the support from rotating, and the blocking piece can stably work for a longer time. And meanwhile, the locking can be unlocked only by driving the blocking piece to move along the reverse direction of the locking by a user.

[0002] Circulation fans are increasingly being used because of their advantages of more uniform air flow, energy saving and power saving, etc. Circulation fans are usually composed of a body and a head. Some circulation fans can fold the head relative to the body, and the head needs to be locked in the unfolded state through a locking mechanism.

[0003] In the related art, the internal locking structure of most foldable fans usually adopts a buckle method. Since these traditional locking methods require the buckle to be able to undergo elastic deformation, they often have the problem of insufficient fixing strength, and the buckle is prone to breakage or permanent deformation during the frequent disassembly and installation process.

[0046] Referring to FIGS. 1 to 5 , a fuselage assembly 100 provided in an embodiment of the present application includes a fuselage rod 10, a bracket 30, and a locking mechanism 50. The bracket 30 is rotatably connected to the fuselage rod 10, and has an unfolded position (as shown in FIGS. 1 and 2 ) and a folded position (as shown in FIG. 3 ). The bracket 30 switches between the unfolded position and the folded position by rotating relative to the fuselage rod 10. The locking mechanism 50 is disposed on the fuselage rod 10, and includes a blocking member 51. The blocking member 51 is movably disposed and is configured to be able to move to block the bracket 30 from rotating toward the folded position when the bracket 30 is in the unfolded position.

[0047] The fuselage assembly 100 is used for the fan 200. Specifically, the fan 200 may be, but is not limited to, a circulation fan. The bracket 30 of the fuselage assembly 100 is used to connect the head 201 of the fan 200. It can be understood that the head 201 of the fan 200 is connected to the bracket 30 and is flipped relative to the fuselage rod 10 through the bracket 30.

[0048] The bracket 30 has a first connection portion 31 and a second connection portion 33, and is rotatably connected to the fuselage rod 10 through the first connection portion 31, and the second connection portion 33 is used to connect the head 201 of the fan 200. The bracket 30 can rotate around a first rotation axis through the first connection portion 31, wherein the first rotation axis is configured to intersect with the height direction of the fuselage assembly 100 (the X direction as shown in FIG. 1).

[0049] The locking mechanism 50 can at least lock the bracket 30 in the unfolded position, that is, when the locking mechanism 50 is locked, the bracket 30 in the unfolded position cannot rotate normally, and cannot be switched to the folded position, and the lock can be released by operation. On the other hand, after the lock is released, the bracket 30 can be rotated to the folded position under the operation of the user or the action of gravity, and can be stably in the folded position under the action of gravity.

[0050] The above-mentioned body assembly 100 is locked by blocking the rotation of the bracket 30 by the blocking member 51. In this process, the blocking member 51 does not need to have the ability to elastically deform. Therefore, the blocking member 51 can have sufficient strength to prevent the bracket 30 from rotating, and the blocking member 51 can work stably for a longer time. At the same time, to unlock, the user only needs to drive the blocking member 51 to move in the opposite direction of the locking.

[0051] In some embodiments, the second connection portion 33 is used to rotatably connect the head 201 of the fan 200 , and in the folded position, the second connection portion 33 is located on the peripheral side of the body rod 10 .

[0052] When the bracket 30 is in the unfolded position, the head 201 of the fan 200 can be in the highest position, and the head 201 can be above the fuselage rod 10. When the bracket 30 is in the folded position, the head 201 of the fan 200 can be located at one side of the fuselage assembly 100. Specifically, the head 201 can be folded to the front of the fuselage rod 10 through the bracket 30 and fit with the fuselage rod 10.

[0053] The head 201 of the fan 200 can be rotatably connected to the second connection part 33 around the second rotation axis. In other words, the head 201 of the fan 200 can be rotated relative to the bracket 30 through the second connection part 33, and the second rotation axis of the head 201 of the fan 200 relative to the bracket 30 is parallel to the first rotation axis of the bracket 30 relative to the body rod 10.

[0054] The second connection part 33 is spaced apart from the first rotation axis, that is, the first connection part 31 and the second connection part 33 are not collinear in the first direction, and the straight line where the first connection part 31 and the second connection part 33 are located intersects with the first direction. Therefore, during the rotation of the bracket 30, the height of the second connection part 33 relative to the fuselage rod 10 can change accordingly, and accordingly, the height of the head 201 rotatably connected to the second connection part 33 also changes accordingly.

[0055] In this way, during the rotation of the bracket 30, since the head 201 and the bracket 30 are rotatably connected, the head 201 can maintain its angle stable by rotating relative to the bracket 30, that is, no matter to which angle the bracket 30 is rotated, the head 201 can maintain a vertical angle. On the one hand, it can work normally as needed, and on the other hand, it can reduce space occupancy.

[0056] Please refer to Figures 6 to 10 together. In some embodiments, when the bracket 30 is switched from the unfolded position to the folded position, the first connection portion 31 rotates along the first direction, and when the bracket 30 is switched from the folded position to the unfolded position, the first connection portion 31 rotates along the second direction. The first connection portion 31 has an unfolding locking surface 311, and the blocking member 51 is configured to move to a rotation path that blocks the unfolding locking surface 311 from rotating along the first direction when the bracket 30 is in the unfolded position.

[0057] It can be understood that the unfolding locking surface 311 is in different positions as the first connecting portion 31 rotates. When the bracket 30 is in the unfolded position, the unfolding locking surface 311 rotates to the vicinity of the blocking member 51, and the blocking member 51 can move to the rotation path of the unfolding locking surface 311 to prevent the bracket 30 from rotating back to the folded position.

[0058] The external force driving the blocking member 51 to move may be, but is not limited to, an elastic force provided by a spring, gravity, or an external force applied by a user.

[0059] In this way, the blocking member 51 can hold the unfolding locking surface 311 to keep the bracket 30 stably in the unfolded position. The blocking member 51 can achieve effective blocking by reducing the displacement distance, and unlocking is also easier.

[0060] Please refer to FIGS. 11 to 13 , in some embodiments, the locking mechanism 50 further includes an elastic member 53, and the blocking member 51 is configured to be able to move along the locking direction (the Y direction as shown in FIG. 13 ) to block the rotation path of the unfolded locking surface 311 along the first turning direction. The elastic member 53 abuts against the blocking member 51 and is configured to provide a driving force to drive the blocking member 51 to move along the locking direction.

[0061] It can be understood that the elastic member 53 can be a spring and be pre-compressed to provide a driving force for driving the blocking member 51 to move along the locking direction.

[0062] In this way, when the blocking member 51 is rotated to the right position at the first connecting portion 31 , that is, when the bracket 30 is in the unfolded position, the blocking member 51 is automatically driven to move along the locking direction to lock the bracket 30 .

[0063] Please refer to FIGS. 14 to 16 , in some embodiments, the locking mechanism 50 further includes a housing 55 and a button 57. The housing 55 is disposed on the body rod 10 and has a pressing channel 551 extending along the locking direction. The button 57 is disposed on the pressing channel 551 and can move along the pressing channel 551. The blocking member 51 is disposed on the button 57.

[0064] It can be understood that the button 57 can reciprocate along the pressing channel 551 . When it moves toward the pressing channel 551 , it can drive the blocking member 51 thereon to move in a direction opposite to the locking direction to release its blocking of the unfolding locking surface 311 .

[0065] In this way, the locking mechanism 50 can be installed on the body rod 10 through its housing 55, and the button 57 can move along the pressing channel 551 to achieve a reciprocating motion in the locking direction, thereby driving the blocking member 51 to reciprocate in the locking direction. The user can overcome the elastic force by pressing the button 57, and the blocking member 51 of the driving group is unlocked.

[0066] In addition, the housing 55 is relatively closed and has a strong supporting strength, and can provide high-strength locking through the blocking member 51 , thereby improving the reliability of the locking mechanism 50 .

[0067] Furthermore, the housing 55 has an active hole 553 connected to the pressing channel 551 and extending in the locking direction. The blocking member 51 extends to the outside of the housing 55 through the active hole 553 and moves along the active hole 553 with the button 57 when the button 57 moves along the pressing channel 551.

[0068] In other words, the blocking member 51 can be partially outside the housing 55 through the movable hole 553, so as to block the rotation path of the unfolding locking surface 311. At the same time, the blocking member 51 can also move through the movable hole 553 to achieve the process of locking and unlocking by movement. The movable hole 553 can limit the movement of the blocking member 51, so that it moves along a specified path.

[0069] In this way, the blocking member 51 can normally realize its function of moving locking and unlocking, and at the same time, its moving path is more accurate under the limit of the movable hole 553. The movement gap between the blocking member 51 and the sliding groove wall of the housing 55 is small, which helps to ensure that the movement of the blocking member 51 is not stuck and is accurately positioned without empty position.

[0070] Furthermore, one end of the pressing channel 551 in the locking direction is an opening 5511 connected to the outside; one end of the button 57 in the locking direction is located in the pressing channel 551, and the other end is exposed from the opening 5511 to the outside of the housing 55 and forms a pressing end 571. One end of the elastic member 53 abuts against the blocking member 51, and the other end abuts against the bottom of the pressing channel 551 away from the opening 5511.

[0071] The button 57 may be partially located in the pressing channel 551, and the length of the button 57 located in the pressing channel 551 may be changed when the button 57 is moved. The pressing end 571 of the button 57 is always exposed outside the housing 55, so that the user can press the button 57 to provide a force to drive the button 57 toward the bottom of the pressing channel 551. The elastic member 53 can provide a force between the blocking member 51 and the bottom of the pressing channel 551 to drive the blocking member 51 away from the bottom of the pressing channel 551, and the elastic member 53 can be in a compressed state at all times during normal use.

[0072] In this way, the user and the elastic member 53 can respectively provide a pair of opposite forces to the button 57 so that it can reciprocate normally to achieve unlocking and locking respectively.

[0073] Specifically, the housing 55 may further include a mounting post 552, which is located at the bottom of the pressing channel 551 away from the opening 5511, and the elastic member 53 is a spring, which is sleeved on the mounting post 552. In this way, the elastic member 53 is accurately positioned and installed.

[0074] Please refer to FIG. 17 . In some embodiments, the button 57 has an insertion hole 572 . The blocking member 51 is inserted into the insertion hole 572 to form an interference fit.

[0075] The blocking member 51 may be, but is not limited to, a columnar latch. In addition, the button 57 may also have a limiting hole 573, and the limiting hole 573 is used to install a spring.

[0076] In this way, the blocking member 51 can be matched with the button 57 in the assembly process by subsequent plugging. Specifically, the button 57 can be first assembled into the pressing hole of the housing 55, and the insertion hole 572 is aligned with the movable hole 553, and then the blocking member 51 is inserted into the insertion hole 572 through the movable hole 553.

[0077] In some embodiments, the first connection portion 31 has a retaining rib 313, the retaining rib 313 forms an unfolding locking surface 311, and the retaining rib 313 also has a sliding surface 315. In the first direction, the sliding surface 315 is located upstream of the unfolding locking surface 311, and the sliding surface 315 is connected to an end of the unfolding locking surface 311 located upstream in the locking direction; wherein the unfolding locking surface 311 is parallel to the locking direction, and the sliding surface 315 intersects with the locking direction.

[0078] It can be understood that when the blocking member 51 moves in the direction opposite to the locking direction, when it moves to the upstream end of the deployment locking surface 311 in the locking direction, the blocking member 51 is about to be separated from the deployment locking surface 311. When the blocking member 51 is officially separated from the deployment locking surface 311, the blocking member 51 can naturally move to the sliding surface 315 located upstream. On the contrary, the blocking member 51 can slide from the sliding surface 315 to the blocking deployment locking surface 311 during the process of switching to the deployment position. In other words, during the process of the bracket 30 switching between the deployment position and the folded position, the blocking member 51 can slide along the sliding surface 315. When switching to the deployment position, the blocking member 51 cuts into the blocking deployment locking surface 311 from the sliding surface 315. When the lock of the deployment position is released, the blocking member 51 slides from the deployment locking surface 311 and enters the sliding surface 315.

[0079] The sliding surface 315 may be an arc surface, an inclined surface, or a combination of the two, and it only needs to allow the blocking member 51 to slide smoothly, and is not specifically limited here.

[0080] Thus, when the lock of the deployed position is released, the blocking member 51 is operated to disengage from the deployment locking surface 311 and can automatically slide along the sliding surface 315 as the bracket 30 rotates. When the bracket 30 rotates to the deployed position, the blocking member 51 can disengage from the sliding surface 315 and, under the action of the elastic member 53, quickly move along the locking direction and block the deployment locking surface 311.

[0081] In some embodiments, the fuselage rod 10 is configured to be retractable to change its length in the height direction of the fuselage assembly 100. It can be understood that the height direction of the fuselage assembly 100 is the height direction of the entire fan 200.

[0082] It can be understood that the fuselage rod 10 can be extended and retracted at least to a certain extent, that is, it can be switched between two lengths through extension and retraction, and each length can be stably maintained.

[0083] In this way, the fuselage assembly 100 can adjust the height of the whole fan 200 by extending and retracting the fuselage rod 10, and can also fold or unfold the head 201 by rotating the bracket 30, which can also adjust the height of the whole fan 200.

[0084] In some embodiments, the bracket 30 includes a first connecting arm 35 and a second connecting arm 37, the first connecting arm 35 and the second connecting arm 37 are both connected to the first connecting part 31, and are respectively arranged on opposite sides of the fuselage rod 10; the ends of the first connecting arm 35 and the second connecting arm 37 away from the first connecting part 31 are respectively formed as second connecting parts 33, and an installation space is formed between the second connecting part 33 of the first connecting arm 35 and the second connecting part 33 of the second connecting arm 37, and the installation space is used to install the head 201.

[0085] It can be understood that the bracket 30 may also include a rotating part, which is rotatably arranged on the fuselage rod 10 and formed as a first connecting part 31, and the first connecting arm 35 and the second connecting arm 37 are respectively connected to the opposite ends of the rotating part. The first connecting arm 35 and the second connecting arm 37 are arranged at intervals, and the head 201 is installed between the two.

[0086] In this way, when the nose 201 is unfolded for use, the installation space can accommodate the nose 201. When the nose 201 is folded to the front of the fuselage assembly 100, the installation space can also serve as an avoidance space for the fuselage rod 10, so that the nose 201 can be fully folded to prevent the bracket 30 and the fuselage rod 10 from interfering with each other during the folding process.

[0087] In some embodiments, the body rod 10 includes a rod body 11 and a rotating seat 13 . The rotating seat 13 is rotatably disposed on the rod body 11 around the height direction of the body assembly 100 . The bracket 30 is rotatably connected to the rotating seat 13 via a first connecting portion 31 .

[0088] It can be understood that the bracket 30 is rotatably connected to the rotating seat 13 through the first connecting portion 31 to realize the rotatable connection with the fuselage rod 10. The rotating seat 13 rotates around the height direction of the fuselage assembly 100 to drive the bracket 30 connected thereto to rotate, and then drives the head 201 connected to the bracket 30 to rotate, realizing the shaking function of the fan 200.

[0089] Specifically, the locking mechanism 50 is also assembled to the rotating seat 13 through its housing 55. A support column 1311 is formed on the rotating seat 13, and the housing 55 has a matching column 554 that matches the support group.

[0090] Please refer to FIG. 18 , in some embodiments, the first connection portion 31 has a first rotational mating surface 317 perpendicular to the first rotation axis, the body rod 10 has a second rotational mating surface perpendicular to the first rotation axis, and the first rotational mating surface 317 and the second rotational mating surface are arranged opposite to each other. Specifically, the second rotational mating surface is located on the rotation seat 13 .

[0091] The body assembly 100 further includes a damping sheet 71 , which is disposed between the first rotational mating surface 317 and the second rotational mating surface, and can contact the first rotational mating surface 317 and the second rotational mating surface at the same time.

[0092] It can be understood that the damping sheet 71 can provide a damping force for the relative rotation between the first rotational mating surface 317 and the second rotational mating surface, that is, provide a damping force for the flipping of the bracket 30 relative to the fuselage rod 10. The damping sheet 71 can provide either linear damping adjustment or instantaneous damping adjustment, which is not specifically limited here.

[0093] In this way, the damping sheet 71 can provide a damping force for the folding of the head 201 of the fan 200, thereby reducing the probability of damage due to over-rapid folding.

[0094] Specifically, a mounting groove 319 is formed on the first rotational mating surface 317 and / or the second rotational mating surface, and the damping plate 71 is installed in the mounting groove 319 .

[0095] In this way, the damping sheet 71 can be stably installed between the first rotational matching surface 317 and the second rotational matching surface through the installation groove 319 .

[0096] Specifically, the first connecting portion 31 has two first rotating mating surfaces 317 spaced apart and arranged opposite to each other, and the rotating seat 13 forms two second rotating mating surfaces arranged opposite to each other, and the two second rotating mating surfaces are located between the two first rotating mating surfaces 317, and the first rotating axis passes through the two first rotating mating surfaces 317 and the two second rotating mating surfaces at the same time. The two first rotating mating surfaces 317 correspond to the two second rotating mating surfaces one by one, and both of the two first rotating mating surfaces 317 have mounting grooves 319 and are provided with damping plates 71, that is, between each first rotating mating surface 317 and its corresponding second rotating mating surface, there is a damping plate 71.

[0097] More specifically, the fuselage assembly 100 also has a bolt 72, which passes through the two first rotating mating surfaces 317 and the two second rotating mating surfaces, connects the first connecting portion 31 and the rotating seat 13 and is fixed by a nut 73. The bolt 72 also serves as a rotating shaft for the two.

[0098] In some embodiments, the fuselage assembly 100 further includes a chassis 90 detachably connected to the fuselage pole 10 .

[0099] In this way, when the fan 200 needs to be stored, the chassis 90 of the body assembly 100 can be removed, thereby further reducing its space occupancy and improving its storage convenience.

[0100] The assembly method of the fuselage assembly 100 is briefly described below: first, the rotating seat 13 is pre-installed on the rod body 11, and the rotating seat 13 has a support column 1311 and a screw through hole. The shell 55 has a matching column 554, a mounting column 552, an opening 5511 and a pressing channel 551. The matching column 554 of the shell 55 is aligned with the support column 1311 on the rotating seat 13 and inserted, and the shell 55 is inserted into the rotating seat 13 through interference fitting, and the screw hole on the first connecting part 31 of the bracket 30 is aligned with the screw through hole of the rotating seat 13, and then the bolt 72 is passed through the screw hole on the bracket 30 and the screw through hole on the rotating seat 13, and then the bracket 30 and the rotating seat 13 are locked and connected together with the nut 73.

[0101] Put the spring onto the mounting post 552 of the shell 55, and then insert the button 57 into the pressing channel 551 of the shell 55 through the opening 5511, with a moderate interference fit so that the insertion hole 572 of the button 57 is aligned with the movable hole 553 of the shell 55. At this time, the button 57 is embedded in the shell 55, and then insert the blocking member 51 horizontally into the insertion hole 572 of the button 57 so that the blocking member 51 is located in the pressing channel 551 of the shell 55, and the blocking member 51 passes through the shell 55.

[0102] When the button 57 is pressed, the blocking member 51 presses the spring, and the blocking member 51 slides along the movable hole 553. At this time, the blocking member 51 does not collide with the expansion locking surface 311 of the retaining rib 313 in the bracket 30, and the bracket 30 can move. When the bracket 30 needs to be locked, the button 57 is released, and the spring acts in the opposite direction on the blocking member 51, so that the blocking member 51 is stuck at the expansion locking surface 311 of the retaining rib 313. The blocking member 51 is located in a relatively closed part of the housing 55, and has sufficient support and locking strength, which can effectively lock the movement of the rotating bracket 30 and accurately position the head 201.

[0103] The above-mentioned fuselage assembly 100 has a blocking member that passes through the shell 55. The shell 55 is relatively closed, has a large supporting strength, sufficient locking strength, and high product reliability. The blocking member 51 and the movable hole 553 of the shell 55 have a small movement gap, ensuring accurate positioning without jamming and without empty positions. By utilizing the elastic force of the spring, the blocking member 51 can quickly reverse and block at the unfolding locking surface 311 of the bracket 30 when the button 57 is released. The structure is simple and compact, the operation is convenient, and effective locking and positioning can be achieved. In this way, the blocking member 51 type locking and positioning structure can significantly improve the use efficiency of mechanical equipment.

[0104] The present application also provides a fan 200 , comprising the above-mentioned body assembly 100 .

[0105] The fan 200 can have a variety of height variations. When the fuselage rod 10 is in the extended state and the bracket 30 is in the unfolded position, the height of the fan 200 is the highest, which can reach L1. On this basis, the fuselage rod 10 is switched to the retracted state, and the height of the fan 200 can be reduced to L2. Further, the head 201 is folded through the bracket 30 until the bracket 30 is in the folded position, and the height of the fan 200 is L3. Among them, L1>L2>L3, L1 can be 1100mm, L2 can be 750mm, and L3 can be 410mm.

[0106] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0107] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
