Machine body assembly and fan

Abstract

The utility model 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.

Description

Technical Field

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

[0002] Circulating fans are becoming increasingly popular due to their advantages, such as more uniform air flow and energy conservation. Circulating fans typically consist of a body and a head. Some fans can fold the head relative to the body, and a locking mechanism is required to lock the head in the unfolded position.

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

[0018] A fan comprises the above-mentioned fuselage assembly.

[0019] The aforementioned body assembly is locked by blocking the bracket's rotation with a blocking member. During this process, the blocking member does not need to be elastically deformable.

[0042] In addition, if the term "and / or" appears, "and / or" is merely a way to describe the association relationship between associated objects, and indicates that three relationships may exist. For example, A and / or B can represent the association relationship between A and B: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that there is an "or" relationship between the associated objects before and after it. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, four, five, etc., unless otherwise clearly and specifically defined.

[0046] See also Figures 1 to 5 The fuselage assembly 100 provided in one 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 (such as Figure 1 、 2 shown) and the folded position (as Figure 3 (As shown). The bracket 30 switches between the deployed and folded positions by rotating relative to the body rod 10. A locking mechanism 50 is provided on the body rod 10 and includes a stopper 51. The stopper 51 is movably disposed and configured to prevent the bracket 30 from rotating toward the folded position when the bracket 30 is in the deployed position.

[0047] The fuselage assembly 100 is used for a fan 200. Specifically, the fan 200 can 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 by 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 via the first connection portion 31, and the second connection portion 33 is used to connect to the head 201 of the fan 200. The bracket 30 can rotate around a first rotation axis via the first connection portion 31, wherein the first rotation axis is configured to be aligned with the height direction of the fuselage assembly 100 (e.g., Figure 1 direction shown).

[0049] The locking mechanism 50 is capable of locking the stand 30 in the deployed position. Specifically, when locked, the stand 30 in the deployed position cannot rotate normally, and thus cannot be switched to the folded position. This lock can be released by manipulation. On the other hand, after being released, the stand 30 can rotate to the folded position by a user or under the force of gravity, and remain stable in the folded position under the force of gravity.

[0050] The aforementioned body assembly 100 locks the bracket 30 by blocking its rotation with the blocking member 51. During this process, the blocking member 51 does not need to be elastically deformable. Therefore, the blocking member 51 can be sufficiently strong to prevent the bracket 30 from rotating, and can operate stably for a longer period of time. Furthermore, unlocking the bracket 30 requires only that the user move the blocking member 51 in the opposite direction of the locking position.

[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 fuselage rod 10 .

[0052] When the bracket 30 is in the extended position, the head 201 of the fan 200 can be in the highest position, above the fuselage pole 10. When the bracket 30 is in the folded position, the head 201 of the fan 200 can be located to the side of the fuselage assembly 100. Specifically, the head 201 can be folded forward of the fuselage pole 10 by the bracket 30 and fit in place with the fuselage pole 10.

[0053] The head 201 of the fan 200 is rotatably connected to the second connection portion 33 about a second rotation axis. In other words, the head 201 of the fan 200 is rotatable relative to the bracket 30 via the second connection portion 33, and the second rotation axis of the fan 200 head 201 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 portion 33 is spaced apart from the first rotation axis. This means that the first connection portion 31 and the second connection portion 33 are not collinear in the first direction, and the line along which the first connection portion 31 and the second connection portion 33 lie intersects the first direction. Therefore, during the rotation of the bracket 30, the height of the second connection portion 33 relative to the body rod 10 can change accordingly, and accordingly, the height of the nose 201, which is rotatably connected to the second connection portion 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 also refer to Figures 6 to 10 In some embodiments, when the bracket 30 switches from the deployed position to the folded position, the first connection portion 31 rotates along a first direction, and when the bracket 30 switches from the folded position to the deployed position, the first connection portion 31 rotates along a second direction. The first connection portion 31 has a deployment locking surface 311, and the blocking member 51 is configured to move to a rotation path that blocks the deployment locking surface 311 from rotating along the first direction when the bracket 30 is in the deployed position.

[0057] It can be understood that the unfolding locking surface 311 is in different positions as the first connecting part 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 bracket 30 stably in the deployed position by abutting against the deployment locking surface 311 . The blocking member 51 can achieve effective blocking by reducing the displacement distance, and unlocking is also easier.

[0060] Please also refer to Figures 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 (such as Figure 13 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, the blocking member 51 can be rotated to the first connection portion 31 , that is, when the bracket 30 is in the deployed position, the blocking member 51 is automatically driven to move along the locking direction to lock the bracket 30 .

[0063] Please also refer to Figures 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 in the pressing channel 551 and is movable 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 move back and forth 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 manner, the locking mechanism 50 can be mounted on the body rod 10 via its housing 55, and the button 57 can reciprocate in the locking direction by moving along the pressing channel 551, 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 a movable 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 movable hole 553 and moves along the movable 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 positioned outside the housing 55 through the movable hole 553, thereby blocking the rotational path of the deployment locking surface 311. Simultaneously, the blocking member 51 can also move through the movable hole 553, enabling locking and unlocking by movement. The movable hole 553 limits the movement of the blocking member 51, allowing it to move along a designated path.

[0069] In this way, the blocking member 51 can normally realize its movement locking and unlocking functions, and at the same time, its movement path is more accurate under the limit of the movable hole 553. The movement clearance between the blocking member 51 and the sliding groove wall of the housing 55 is small, which helps to ensure that the blocking member 51 moves without stagnation and is accurately positioned without any empty space.

[0070] Furthermore, one end of the pressing channel 551 in the locking direction is an opening 5511 that communicates with the outside world. One end of the button 57 in the locking direction is located within the pressing channel 551, while the other end is exposed outside the housing 55 through the opening 5511 and forms a pressing end 571. One end of the elastic member 53 abuts the blocking member 51, while the other end abuts the bottom of the pressing channel 551 away from the opening 5511.

[0071] The button 57 can be partially located within the pressing channel 551, and the length of the button 57 within the pressing channel 551 can be changed during movement. The pressing end 571 of the button 57 is always exposed outside the housing 55, allowing the user to press it, thereby applying a force to drive the button 57 toward the bottom of the pressing channel 551. The elastic member 53 is able to exert 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. The elastic member 53 can be kept 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 move back and forth 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. The elastic member 53 is a spring and is sleeved on the mounting post 552. In this way, the elastic member 53 is accurately positioned and installed.

[0074] Please also refer to Figure 17 In some embodiments, the button 57 has a socket 572 , and the blocking member 51 is inserted into the socket 572 to form an interference fit.

[0075] Wherein, the blocking member 51 can be but is not limited to a columnar latch. In addition, the button 57 can 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 by subsequent plugging during the assembly process. 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 connecting portion 31 has a retaining rib 313, which forms an expansion locking surface 311. The retaining rib 313 also has a sliding surface 315. In the first direction of rotation, the sliding surface 315 is located upstream of the expansion locking surface 311 and is connected to the upstream end of the expansion locking surface 311 in the locking direction. The expansion locking surface 311 is parallel to the locking direction, while the sliding surface 315 intersects the locking direction.

[0078] It is understood that when the blocking member 51 moves in a direction opposite to the locking direction, it will be about to disengage from the deployment locking surface 311 when it moves to the upstream end of the deployment locking surface 311 in the locking direction. When the blocking member 51 officially disengages from the deployment locking surface 311, it can naturally move to the upstream sliding surface 315. Conversely, the blocking member 51 can slide from the sliding surface 315 to the deployment blocking locking surface 311 during the process of switching to the deployed position. In other words, when the bracket 30 switches between the deployed position and the folded position, the blocking member 51 can slide along the sliding surface 315. When switching to the deployed position, the blocking member 51 cuts into the deployment blocking locking surface 311 from the sliding surface 315. When the deployment position is unlocked, the blocking member 51 slides from the deployment locking surface 311 and then slides along the sliding surface 315.

[0079] The sliding surface 315 may be an arc surface, an inclined surface, or a combination thereof, as long as it allows the blocking member 51 to slide smoothly, and is not specifically limited here.

[0080] Thus, when the lock on the deployed position is released, the blocking member 51 is disengaged 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 in the locking direction and block the deployment locking surface 311.

[0081] In some embodiments, the fuselage rod 10 is configured to be telescopic 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 once, that is, it can be switched between two lengths through extension and retraction, and each length can be kept stable.

[0083] In this way, the fuselage assembly 100 can adjust the height of the entire 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 entire 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 is understood that the bracket 30 may further include a rotating portion that is rotatably disposed through the fuselage rod 10 and forms a first connecting portion 31. A first connecting arm 35 and a second connecting arm 37 are respectively connected to opposite ends of the rotating portion. The first connecting arm 35 and the second connecting arm 37 are spaced apart, and the nose 201 is mounted therebetween.

[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 base 13 . The rotating base 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 base 13 via a first connecting portion 31 .

[0088] As can be understood, the bracket 30 is rotatably connected to the rotating base 13 via the first connecting portion 31, thereby achieving a rotatable connection with the fuselage rod 10. Rotating the rotating base 13 about the height direction of the fuselage assembly 100 can drive the bracket 30 connected thereto to rotate, thereby driving the head 201 connected to the bracket 30 to rotate, realizing the oscillating function of the fan 200.

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

[0090] Please also refer to Figure 18 In some embodiments, the first connecting portion 31 has a first rotational mating surface 317 perpendicular to the first rotation axis, and the body rod 10 has a second rotational mating surface perpendicular to the first rotation axis. The first rotational mating surface 317 and the second rotational mating surface are disposed opposite each other. Specifically, the second rotational mating surface is located on the rotating seat 13.

[0091] The body assembly 100 further includes a damping plate 71 . The damping plate 71 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 is understood that the damping plate 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, it can provide a damping force for the tilting of the bracket 30 relative to the body rod 10. The damping plate 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 plate 71 can be stably installed between the first rotational fitting surface 317 and the second rotational fitting surface through the installation groove 319 .

[0096] Specifically, the first connecting portion 31 has two first rotational mating surfaces 317 spaced apart and arranged opposite each other. The rotating seat 13 forms two second rotational mating surfaces disposed opposite each other. The two second rotational mating surfaces are located between the two first rotational mating surfaces 317, and the first rotation axis passes through both the two first rotational mating surfaces 317 and the two second rotational mating surfaces. The two first rotational mating surfaces 317 correspond to the two second rotational mating surfaces in a one-to-one manner. Both first rotational mating surfaces 317 have mounting grooves 319 and are equipped with damping plates 71. That is, a damping plate 71 is located between each first rotational mating surface 317 and its corresponding second rotational mating surface.

[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 the rotating shaft of 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, further reducing its space occupation and improving its storage convenience.

[0100] The following briefly describes the assembly method of the aforementioned fuselage assembly 100: First, pre-install the rotating base 13 onto the rod body 11. The rotating base 13 has a support column 1311 and a screw hole. The housing 55 has a mating column 554, a mounting column 552, an opening 5511, and a pressing channel 551. The mating column 554 of the housing 55 is aligned with the support column 1311 on the rotating base 13 and inserted. An interference fit is performed so that the housing 55 is embedded in the rotating base 13. The screw hole on the first connecting portion 31 of the bracket 30 is aligned with the screw hole on the rotating base 13. Then, a bolt 72 is inserted through the screw hole on the bracket 30 and the screw hole on the rotating base 13. The bracket 30 and the rotating base 13 are then locked together using a nut 73.

[0101] Put the spring onto the mounting post 552 of the shell 55, 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 socket 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 socket 572 of the button 57 while making the blocking member 51 located in the pressing channel 551 of the shell 55, and the blocking member 51 passes through the shell 55.

[0102] When button 57 is pressed, blocking member 51 compresses the spring, causing blocking member 51 to slide along movable hole 553. At this point, blocking member 51 does not contact the deployment locking surface 311 of retaining rib 313 in bracket 30, allowing bracket 30 to move. To lock bracket 30, button 57 is released, and the spring acts in the opposite direction on blocking member 51, causing it to engage the deployment locking surface 311 of retaining rib 313. Blocking member 51 is located within the relatively enclosed portion of housing 55, providing sufficient support and locking strength to effectively lock the movement of rotating bracket 30 and accurately position handpiece 201.

[0103] The aforementioned fuselage assembly 100 has a stopper extending through the housing 55, which is relatively closed, providing strong support and locking strength, and high product reliability. The clearance between the stopper 51 and the movable hole 553 of the housing 55 is small, ensuring precise positioning without any jamming or deadlock. The spring force allows the stopper 51 to quickly reverse and block against the unfolded locking surface 311 of the bracket 30 when the button 57 is released. This structure is simple and compact, easy to operate, and enables effective locking and positioning. Thus, the locking and positioning structure of the stopper 51 can significantly improve the 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 various height variations. When the fuselage rod 10 is extended and the bracket 30 is in the deployed position, the fan 200 reaches its highest height, L1. Furthermore, by retracting the fuselage rod 10, the fan 200 can be lowered to L2. Furthermore, by folding the nose 201 through the bracket 30 until the bracket 30 is in the folded position, the fan 200 reaches a height of L3. Here, L1>L2>L3, where L1 can be 1100mm, L2 can be 750mm, and L3 can be 410mm.

[0106] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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 merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
