[0043] See also Figures 1 to 5 A 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 is used to mount the head 201 of the fan 200. The bracket 30 has an extended position and a folded position that can be switched by rotating relative to the fuselage rod 10. The locking mechanism 50 is provided on the fuselage rod 10 and includes a blocking member 51. The blocking member 51 is movably provided, and when the bracket 30 is in the extended position, the blocking member 51 can move to prevent the bracket 30 from rotating toward the folded position.

[0044] The fuselage assembly 100 is used to house a fan 200. Specifically, the fan 200 may be, but is not limited to, a circulating fan. The bracket 30 of the fuselage assembly 100 is used to connect the head 201 of the fan 200. It is understood that the head 201 of the fan 200 is connected to the bracket 30 and can be rotated relative to the fuselage rod 10 via the bracket 30. Furthermore, the fuselage assembly 100 may also include a chassis 90, etc., which will not be detailed here.

[0045] The bracket 30 has a first connection end 31 and a second connection end 33, and is rotatably connected to the fuselage rod 10 via the first connection end 31. The second connection end 33 is used to connect to the head 201 of the fan 200. The bracket 30 can rotate relative to the fuselage rod 10 around a first axis via the first connection end 31. The first axis is configured to be aligned with the height direction of the fuselage assembly 100 (e.g., Figure 1 The X direction shown) intersects.

[0046] The locking mechanism 50 is capable of locking the stand 30 in the deployed position. That is, the stand 30 cannot rotate normally in the deployed position due to the obstruction of the blocking member 51 of the locking mechanism 50, and thus cannot be switched to the folded position. Alternatively, the blocking member 51 can be released by reverse movement. After release, the stand 30 can be rotated to the folded position by a user or under the action of gravity, and can remain stable in the folded position under the action of gravity.

[0047] The bracket 30 of the aforementioned body assembly 100 can be used to mount the head 201, and the head 201 mounted thereon can be flipped over via the bracket 30. When the bracket 30 is in the unfolded position, the head 201 is in an unfolded state suitable for normal use. When the bracket 30 is in the folded position, the head 201 is folded relative to the body rod 10 to be in a folded state convenient for storage. Simultaneously, the blocking member 51 of the locking mechanism 50 can lock the rotation of the bracket 30 to improve the stability of the head 201 when unfolded. In this way, the fan 200 can quickly reduce space usage by folding the head 201, achieving the purpose of storage. There is no need to disassemble the fan 200 from top to bottom, making storage and practical use more convenient.

[0048] Furthermore, the second connection end 33 is used to rotatably connect to the head 201 of the fan 200 , and in the folded position, the second connection end 33 is located on the peripheral side of the fuselage rod 10 .

[0049] 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.

[0050] The head 201 of the fan 200 is rotatable about a second axis and connected to the second connection end 33. In other words, the head 201 of the fan 200 is rotatable relative to the bracket 30 via the second connection end 33, and the second axis of rotation of the head 201 of the fan 200 relative to the bracket 30 is parallel to the first axis of rotation of the bracket 30 relative to the body rod 10.

[0051] The second connecting end 33 is spaced apart from the first axis. That is, the first connecting end 31 and the second connecting end 33 are not collinear in the first direction, and the line along which the first connecting end 31 and the second connecting end 33 lie intersects the first direction. Therefore, during the rotation of the bracket 30, the height of the second connecting end 33 relative to the fuselage rod 10 can change accordingly, and accordingly, the height of the nose 201, which is rotatably connected to the second connecting end 33, also changes accordingly.

[0052] In this way, during the rotation of the bracket 30, since the head 201 is rotatably connected to the bracket 30, 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 and fit tightly against the fuselage rod 10 after folding.

[0053] In some embodiments, the blocking member 51 is configured to move in the locking direction to block the bracket 30 from rotating toward the folded position. The locking mechanism 50 further includes an elastic member 53 that abuts against the blocking member 51 and is configured to provide a driving force to drive the blocking member 51 to move in the locking direction.

[0054] It is understood that when the bracket 30 is in the deployed state, the elastic force provided by the elastic member 53 can drive and maintain the blocking member 51 to block the bracket 30. The blocking member 51 can move in the locking direction or in the direction opposite to the locking direction, and is fixed in rotation about the first axis.

[0055] After the blocking member 51 moves in the locking direction to block the bracket 30, it can at least prevent the bracket from rotating toward the folded position. Accordingly, overcoming the elastic force to drive the blocking member 51 in a direction opposite to the locking direction can eliminate the obstruction. Specifically, the elastic member 53 can be, but is not limited to, a spring.

[0056] In this way, the blocking member 51 can automatically lock the bracket 30 when the bracket 30 is in the expanded state under the action of the elastic member 53 .

[0057] Please also refer to Figure 6 Furthermore, the blocking member 51 has a locking end 511, and the end face of the locking end 511 is a guide end face 5111. The blocking member 51 blocks the bracket 30 from rotating toward the folded position through the guide end face 5111, and the guide end face 5111 intersects with the locking direction.

[0058] Specifically, the blocking member 51 is a positioning bead, specifically a press-in positioning bead. When its locking end 511 blocks the bracket 30, the bracket 30 can generate pressure perpendicular to the guide end surface 5111, and the pressure has a component force opposite to the locking direction.

[0059] It is understood that to achieve normal function, in the absence of any other external force, the elastic force provided by the elastic member 53 is sufficient to support the guide end surface 5111 of the blocking member 51 to prevent the bracket 30 from rotating toward the folded position. When the user needs to fold the handpiece 201, they only need to apply an external force to the handpiece 201 or the bracket 30 to drive it toward the folded position, thereby generating a pressure on the guide end surface 5111 sufficient to overcome the elastic member 53, pressing the blocking member 51 in a direction opposite to the locking direction until it can no longer block the bracket 30 from rotating about the first axis, thereby releasing the lock on the bracket 30.

[0060] Thus, when using the fan 200, the user only needs to naturally unfold the bracket 30. After it is fully unfolded, the blocking member 51 can automatically lock the bracket 30 under the action of the elastic member 53. When the fan 200 needs to be folded, the user only needs to apply external force and press down the head 201 to automatically unlock it and complete the folding.

[0061] In some embodiments, the bracket 30 is rotatably connected to the fuselage rod 10 about a first axis. The bracket 30 has a positioning hole 3111 spaced apart from the first axis. When the bracket 30 is in the deployed position, the positioning hole 3111 is located in the movement path of the blocking member 51 in the locking direction. The blocking member 51 can move in the locking direction until the locking end 511 partially engages the positioning hole 3111, and the guide end surface 5111 abuts the edge of the positioning hole 3111.

[0062] It is understood that the positioning hole 3111 is spaced apart from the first axis, meaning that as the bracket 30 rotates, the positioning hole 3111 also rotates about the first axis. When the bracket 30 rotates to the deployed position, the positioning hole 3111 is located in the path of the blocking member 51 in the locking direction. Driven by the elastic member 53, the blocking member 51 can move in the locking direction until the locking end 511 partially engages with the positioning hole 3111. Once the blocking member 51 engages with the positioning hole 3111, the positioning hole 3111 is restrained by the blocking member 51 and cannot rotate. Accordingly, the bracket 30 cannot rotate either.

[0063] In this way, the locking mechanism 50 can engage the positioning hole 3111 with its locking end 511, thereby preventing the bracket 30 from rotating about the first axis, thereby blocking the bracket 30 from rotating. When the handpiece 201 is folded, the edge of the positioning hole 3111 can press against the guide end surface 5111, forcing the blocking member 51 to retract and disengage from the positioning hole 3111, thereby losing its blocking function.

[0064] Furthermore, the guide end surface 5111 of the blocking member 51 is an arc-shaped surface convex along the locking direction. Specifically, the guide end surface 5111 can be a spherical surface.

[0065] In this way, when the pressure generated by the bracket 30 is sufficient to overcome the elastic force of the elastic member 53 , the bracket 30 can push the blocking member 51 to move along the locking direction under the guidance of the arc-shaped guide end surface 5111 .

[0066] It can be understood that in some other embodiments, the guide end surface 5111 can also be a slope, a cone, etc., which intersects with the locking direction so that the force perpendicular to the surface can generate a force in a direction opposite to the locking direction. No specific limitation is made here.

[0067] Please also refer to Figures 7 to 9 In some embodiments, the bracket 30 has a locking fitting structure 311, which is located on the circumferential side of the first axis and spaced apart from the first axis. The positioning hole 3111 is located in the locking fitting structure 311, and the locking direction is perpendicular to the first axis.

[0068] In this way, the positioning hole 3111 can rotate around the first axis, and when the bracket 30 is in the expanded position, the blocking member 51 can be locked into the positioning hole 3111 along a locking direction perpendicular to the first axis, thereby generating a blocking effect.

[0069] In some other embodiments, the locking mating structure 311 may also be perpendicular to the first axis, the positioning hole 3111 is located on the locking mating structure 311, its axis is parallel to and spaced from the first axis, the locking direction is parallel to the first axis, etc. It is only necessary to enable the blocking member 51 to be able to fit into the positioning hole 3111 and block the rotation of the bracket 30 around the first axis when the bracket 30 is in the expanded position, and no specific limitation is made here.

[0070] Furthermore, the locking engagement structure 311 includes a base portion 3112 and a curved slider 3113. The base portion 3112 has a mounting groove 3114 on its surface facing the first axis. The curved slider 3113 is disposed within the mounting groove 3114, forming a positioning hole 3111. When the bracket 30 switches between the deployed and folded positions, the blocking member 51 abuts against the curved slider 3113 in the locking direction and is able to slide along the curved slider 3113.

[0071] It can be understood that the locking fitting is located in the locking direction of the blocking member 51, the arcuate slider can be an arc shape around the first axis, and the assembly groove 3114 formed by the collective part is contoured with the arcuate slider.

[0072] During the process of the bracket 30 rotating from the unfolded position to the folded position, the locking end 511 of the blocking member 51 first disengages from the positioning hole 3111 under the action of squeezing, and abuts against the area of ​​the arc-shaped slider other than the positioning hole 3111, and the bracket 30 recovers its rotation ability. During the process of the bracket 30 rotating, the arc-shaped slider rotates relative to the blocking member 51, and the blocking member 51 slides along the arc-shaped slider 3113 through its locking end 511.

[0073] During the process of the bracket 30 rotating from the folded position to the unfolded position, the locking end 511 of the blocking member 51 slides along the arc-shaped slider 3113 until the bracket 30 rotates to the unfolded position, and the locking end 511 of the blocking member 51 slides to the positioning hole 3111 accordingly, and is locked into the positioning hole 3111 under the action of the elastic member 53.

[0074] Thus, the arc-shaped slider 3113 can be made of a relatively smooth material and formed with a positioning hole 3111. The slider can then be installed in the assembly groove 3114. The positioning hole 3111 allows the slider to be positioned and engaged with the blocking member 51, while the area outside the positioning hole 3111 allows the slider to slide and engage with the blocking member 51. Furthermore, the arc-shaped slider can be detachable and replaceable.

[0075] Specifically, the assembly groove 3114 has a spring buckle 3116 and two spaced-apart limiting ribs 3115. During installation, the arc-shaped slider is located between the two limiting ribs 3115, with one end inserted into the spring buckle 3116, and both sides are limited by the limiting ribs 3115 to achieve positioning installation.

[0076] Please also refer to Figure 10 In some embodiments, the locking mechanism 50 further includes an assembly member 55 disposed on the body rod 10 and having an assembly hole 551 extending along the locking direction. The elastic member 53 is disposed in the assembly hole 551. The blocking member 51 is at least partially located in the assembly hole 551 and is movable along the assembly hole 551.

[0077] It is understandable that the blocking member 51 can move outward from the assembly hole 551 under the action of the elastic member 53 to engage with the positioning hole 3111 , and can also move into the assembly hole 551 under the pressure of the bracket 30 to disengage from the positioning hole 3111 .

[0078] Thus, the locking mechanism 50 is fixedly mounted on the fuselage rod 10 via the assembly member 55. The assembly hole 551 therein provides space for the blocking member 51 to move, restricting the blocking member 51 to movement along the extension direction of the assembly hole 551 and preventing rotation about the first axis, thereby improving the positioning effect. The clearance between the blocking member 51 and the assembly member 55 is small, ensuring accurate positioning without any jamming or gaps.

[0079] Please also refer to Figure 11 Furthermore, the fuselage rod 10 includes a rod body 11 and a support 13. The support 13 can be movably arranged on the rod body 11 around a third axis. The bracket 30 is rotatably connected to the support 13 around a first axis. The first axis intersects with the third axis. The assembly part 55 is arranged on the support 13.

[0080] Specifically, the third axis is parallel to the height direction of the fuselage assembly 100, and the support 13 can rotate around the third axis to drive the bracket 30 connected thereto to rotate. In addition, the rod body 11 is configured to be able to extend and retract to change its own length.

[0081] In this way, the bracket 30 and the locking mechanism 50 can rotate together with the support 13 , thereby realizing the oscillating function of the fan 200 while reducing its influence on the locking function of the locking mechanism 50 .

[0082] Furthermore, the support 13 has a support column 131, and the assembly part 55 has a pillar 552 that cooperates with the support column 131; and / or, the support 13 has two limiting portions 133 arranged at intervals, the assembly part 55 is arranged between the two limiting portions 133, and the assembly part 55 has a limiting matching portion 553, and the lower end face 5531 of the limiting matching portion 553 abuts and cooperates with the top end face 1331 of the limiting portion 133.

[0083] In this way, the support 13 can achieve positioning cooperation with the assembly part 55, thereby improving the position stability of the assembly part 55 and the blocking member 51 provided thereon.

[0084] In some embodiments, the bracket 30 has a first rotational mating surface 313 perpendicular to the first axis; the body rod 10 has a second rotational mating surface 1335 perpendicular to the first axis, and the first rotational mating surface 313 and the second rotational mating surface 1335 are arranged opposite to each other.

[0085] The body assembly 100 further includes a damping plate 71 . The damping plate 71 is disposed between the first rotational mating surface 313 and the second rotational mating surface 1335 and is capable of contacting both the first rotational mating surface 313 and the second rotational mating surface 1335 at the same time.

[0086] It is understood that the damping plate 71 can provide a damping force for the relative rotation between the first rotational mating surface 313 and the second rotational mating surface 1335, 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.

[0087] 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.

[0088] Specifically, a mounting groove 315 is defined on the first rotational mating surface 313 and / or the second rotational mating surface 1335 , and the damping plate 71 is installed in the mounting groove 315 .

[0089] In this way, the damping plate 71 can be stably installed between the first rotational fitting surface 313 and the second rotational fitting surface 1335 through the installation groove 315 .

[0090] Specifically, the base portion 3112 has two first rotational mating surfaces 313 spaced apart and facing each other, with a first through-hole 317 formed on each of the two first rotational mating surfaces 313. The mounting groove 3114 is located between the two first rotational mating surfaces 313. The two opposing surfaces of the two retaining portions 133 of the support 13 each form a second rotational mating surface 1335. The two second rotational mating surfaces 1335 are located between the two first rotational mating surfaces 313 and have a second through-hole 1333. The first axis passes through both the first through-holes 317 of the two first rotational mating surfaces 313 and the second through-holes 1333 of the two second rotational mating surfaces 1335. The first axis also serves as the axis of the first through-holes 317 and the second through-holes 1333. The two first rotating mating surfaces 313 and the two second rotating mating surfaces 1335 correspond one to one, and both first rotating mating surfaces 313 have mounting grooves 315 and are provided with damping plates 71, that is, there is a damping plate 71 between each first rotating mating surface 313 and its corresponding second rotating mating surface 1335, and the damping plate 71 has a third through hole 711 aligned with the first through hole 317 and the second through hole 1333.

[0091] More specifically, the fuselage assembly 100 also has a bolt 72, which passes through the first through hole 317 on the two first rotating mating surfaces 313, the second through hole 1333 on the two second rotating mating surfaces 1335, and the third through hole 711 on the damping plate 71, and is fixed by a nut 73 to rotate the first connecting end 31 and the support 13, and the bolt 72 serves as the rotating axis of the two.

[0092] 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 end 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 end 31 are respectively formed as second connecting ends 33, and an installation space is formed between the second connecting end 33 of the first connecting arm 35 and the second connecting end 33 of the second connecting arm 37, and the installation space is used to install the head 201.

[0093] 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.

[0094] The following is a brief description of the assembly method of the fuselage assembly 100: First, the support 13 is fixed to the rod body 11. The support 13 has a support column 131 and a through hole. The assembly part 55 has a support column 552 and an assembly hole 551.

[0095] Following the contours of the assembly member 55 and the support 13, the lower end surface 5531 of the position-limiting mating portion 553 is brought into contact with the top surface 1331 of the position-limiting portion 133, and the support column 131 on the support 13 is inserted into the pillar 552 of the assembly member 55, ultimately connecting the assembly member 55 to the support 13. Next, the spring, serving as the elastic member 53, is installed into the assembly hole 551 of the assembly member 55, and the blocking member 51 is then installed into the spring.

[0096] Install the damping plate 71 into the mounting slot 315 of the bracket 30, aligning the third through-hole 711 of the damping plate 71 with the first through-hole 317 of the bracket 30. Engage one end of the curved slider 3113 inside the spring catch 3116 of the bracket 30, while securing the retaining ribs 3115 against both sides of the curved slider 3113 to secure it to the assembly slot 3114 of the bracket 30.

[0097] Align the first through hole 317 of the bracket 30 with the second through hole 1333 of the support 13, then pass the bolt 72 through the second through hole 1333, the first through hole 317, and the third through hole 711 of the bracket 30, and tighten with the nut 73. At this point, the bracket 30 and the support 13 are fixed together.

[0098] When the nose 201 of the aforementioned body assembly 100 is tilted downward, the curved slider 3113 in the bracket 30 presses against the bumper, which compresses the spring. The bumper then disengages from the positioning hole 3111, allowing the bracket 30 to move, allowing the nose 201 to be folded and attached to the body. When the nose 201 needs to be raised, the bracket 30 is lifted upward, and the bumper engages the positioning hole 3111, effectively locking the bracket 30 and securing the nose 201.

[0099] The present application further provides a fan 200, comprising the above-mentioned body assembly 100. Specifically, the fan 200 may be, but is not limited to, a circulation fan, a table fan, or the like.

[0100] 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.

[0101] 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.
