[0043] Referring to FIGS. 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 unfolded position and a folded position that can be switched 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 when the bracket 30 is in the unfolded position, the blocking member 51 can be moved to block the bracket 30 from rotating toward the folded position.

[0044] 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 can be turned relative to the fuselage rod 10 through the bracket 30. In addition, the fuselage assembly 100 may also include a chassis 90, etc., which will not be repeated 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 intersect with the height direction of the fuselage assembly 100 (the X direction as shown in FIG. 1 ).

[0046] The locking mechanism 50 can at least lock the bracket 30 in the unfolded position, that is, the bracket 30 in the unfolded position cannot rotate normally under the obstruction of the blocking member 51 of the locking mechanism 50, and cannot be switched to the folded position. On the other hand, the obstruction can be released by reverse movement, and after being 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.

[0047] The bracket 30 of the above-mentioned fuselage assembly 100 can be used to install the head 201, and the head 201 installed thereon can be turned over by the bracket 30. When the bracket 30 is in the unfolded position, the head 201 is in an unfolded state that can be used normally. When the bracket 30 is in the folded position, the head 201 is folded relative to the fuselage rod 10 to be in a folded state that is easy to store. At the same time, 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 the space occupied by folding the head 201 to achieve the purpose of storage, and there is no need to disassemble the fan 200 from top to bottom in sequence, which makes storage and practical use more convenient.

[0048] Furthermore, the second connection end 33 is used to rotatably connect 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 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.

[0050] The head 201 of the fan 200 can be rotated around the second axis to connect the second connection end 33. In other words, the head 201 of the fan 200 can be rotated relative to the bracket 30 through 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 connection end 33 is spaced apart from the first axis, that is, the first connection end 31 and the second connection end 33 are not collinear in the first direction, and the straight line where the first connection end 31 and the second connection end 33 are located intersects the first direction. Therefore, during the rotation of the bracket 30, the height of the second connection end 33 relative to the fuselage rod 10 can change accordingly, and accordingly, the height of the head 201 rotatably connected to the second connection 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 closely to the fuselage rod 10 after folding.

[0053] In some embodiments, the blocking member 51 is configured to move along the locking direction to block the bracket 30 from rotating toward the folded position. The locking mechanism 50 further includes an elastic member 53, which 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.

[0054] It can be 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 around the first axis.

[0055] After the blocking member 51 moves along the locking direction to block the bracket 30, it can at least prevent it from rotating toward the folded position. Accordingly, the blocking can be eliminated by overcoming the elastic force to drive the blocking member 51 to move in the direction opposite to the locking direction. 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 unfolded state under the action of the elastic member 53 .

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

[0058] Specifically, the blocking member 51 is a positioning bead, specifically a press-in positioning bead, and 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 can be understood that, in order to achieve its normal function, in the absence of other external forces, the elastic force provided by the elastic member 53 is sufficient to support the guide end surface 5111 of the blocking member 51 to block the bracket 30 from rotating toward the folded position. When the user needs to fold the machine head 201, he only needs to apply an external force to the machine head 201 or the bracket 30 to drive it to rotate toward the folded position, so as to generate a pressure on the guide end surface 5111 sufficient to overcome the elastic member 53, and press the blocking member 51 in the direction opposite to the locking direction until it can no longer block the bracket 30 from rotating in the direction around the first axis, so as to release the locking of the bracket 30.

[0060] Thus, when using the fan 200, the user only needs to unfold the bracket 30 naturally, and after the bracket 30 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 to press down the head 201 to automatically unlock and complete the folding.

[0061] In some embodiments, the bracket 30 is connected to the fuselage rod 10 by rotation around the first axis, and the bracket 30 has a positioning hole 3111, and the positioning hole 3111 is spaced apart from the first axis. When the bracket 30 is in the deployed position, the positioning hole 3111 is on the moving path of the blocking member 51 along the locking direction, and the blocking member 51 can move along the locking direction until the locking end 511 is partially inserted into the positioning hole 3111, and the guide end surface 5111 abuts against the edge of the positioning hole 3111.

[0062] It can be understood that the positioning hole 3111 is spaced apart from the first axis, that is, during the rotation of the bracket 30, the positioning hole 3111 also rotates around the first axis. When the bracket 30 rotates to the unfolded position, the positioning hole 3111 is on the moving path of the blocking member 51 along the locking direction, that is, the blocking member 51 can be driven by the elastic member 53 to move along the locking direction until the locking end 511 is partially inserted into the positioning hole 3111. After the blocking member 51 is inserted into the positioning hole 3111, the positioning hole 3111 is limited by the blocking member 51 and cannot rotate, and accordingly, the bracket 30 cannot rotate either.

[0063] In this way, the locking mechanism 50 can be inserted into the positioning hole 3111 through its locking end 511, and the bracket 30 can be stopped from rotating around the first axis, thereby completing the blocking of the bracket 30. When the head 201 is folded, the edge of the positioning hole 3111 can press against the guide end surface 5111, and force the blocking member 51 to retreat and disengage from the positioning hole 3111, so that it loses its blocking function.

[0064] Further, the guide end surface 5111 of the blocking member 51 is an arc-shaped surface convex outwardly 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 the opposite direction to the locking direction. No specific limitation is made here.

[0067] Please refer to Figures 7 to 9. In some embodiments, the bracket 30 has a locking matching 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 matching 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 unfolded position, the blocking member 51 can be inserted 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 matching structure 311 may also be perpendicular to the first axis, the positioning hole 3111 is located on the locking matching 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 matching structure 311 includes a base portion 3112 and an arc-shaped slider 3113. The surface of the base portion 3112 facing the first axis has a mounting groove 3114. The arc-shaped slider 3113 is disposed in the mounting groove 3114 to form a positioning hole 3111. When the bracket 30 switches between the unfolded position and the folded position, the blocking member 51 abuts against the arc-shaped slider 3113 along the locking direction and can slide along the arc-shaped slider 3113.

[0071] It can be understood that the locking fitting is located in the direction of the blocking member 51 in the locking direction, the arc-shaped slider can be an arc shape around the first axis, and the assembly groove 3114 formed by the collective part is contoured with the arc-shaped 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 effect of squeezing, and abuts against the area of ​​the arc-shaped slide except the positioning hole 3111, and the bracket 30 restores its rotation ability. During the process of the bracket 30 rotating, the arc-shaped slide and the blocking member 51 rotate relative to each other, and the blocking member 51 slides along the arc-shaped slider 3113 through its locking end 511.

[0073] When the bracket 30 rotates 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 snapped into the positioning hole 3111 under the action of the elastic member 53.

[0074] In this way, the arc-shaped slider 3113 can be installed in the assembly groove 3114 by simply selecting a relatively smooth material and drilling a hole 3111 thereon to form a positioning hole 3111, and then the arc-shaped slider can be positioned and matched with the blocking member 51 through the positioning hole 3111, and can be slidably matched with the blocking member 51 through the area outside the positioning hole 3111. In addition, the arc-shaped slider can be detachable and can be replaced.

[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 limited by the limiting ribs 3115 to achieve positioning installation.

[0076] Please refer to FIG. 10 , in some embodiments, the locking mechanism 50 further includes an assembly member 55, which is disposed on the body rod 10 and has an assembly hole 551 extending along the locking direction, and 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 can move along the assembly hole 551.

[0077] It can be understood that the blocking member 51 can move outward from the assembly hole 551 under the action of the elastic member 53 to be inserted into the positioning hole 3111 , and can also move into the assembly hole 551 under the pressure of the bracket 30 to be disengaged from the positioning hole 3111 .

[0078] In this way, the locking mechanism 50 is fixedly mounted on the fuselage rod 10 through the assembly part 55, and the assembly hole 551 thereon provides a moving space for the blocking member 51, and also limits the blocking member 51 to only move along the extension direction of the assembly hole 551, and will not rotate around the first axis, thereby improving the positioning effect. The movement gap between the blocking member 51 and the assembly part 55 is small, ensuring accurate positioning without jamming and without empty space.

[0079] Please refer to Figure 11. Further, 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 swing function of the fan 200 and reducing the influence of the fan 200 on the locking function of the locking mechanism 50.

[0082] Further, 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 that are spaced apart, 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 surface 5531 of the limiting matching portion 553 is abutted and matched with the top end surface 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 arranged 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 sheet 71 , which is disposed between the first rotational mating surface 313 and the second rotational mating surface 1335 , and can contact the first rotational mating surface 313 and the second rotational mating surface 1335 at the same time.

[0086] It can be understood that the damping sheet 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, 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.

[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 provided on the first rotational mating surface 313 and / or the second rotational mating surface 1335 , and the damping sheet 71 is installed in the mounting groove 315 .

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

[0090] Specifically, the base portion 3112 has two first rotational mating surfaces 313 that are spaced apart and disposed opposite to each other, and a first through hole 317 is formed on the two first rotational mating surfaces 313, and the assembly groove 3114 is located between the two first rotational mating surfaces 313. The surfaces opposite to each other of the two limiting portions 133 of the support 13 are each formed into a second rotational mating surface 1335, and 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 simultaneously passes through 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, and the first axis is also the hole axis of the first through hole 317 and the second through hole 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, a damping plate 71 is provided 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 enable the first connecting end 31 to be rotatably connected to the support 13, and the bolt 72 serves as a rotating axis for 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, and 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] With the outer contours of the assembly part 55 and the support 13, the lower end surface 5531 of the limiting matching part 553 is brought close to the top end surface 1331 of the limiting part 133, so that the support column 131 on the support 13 is inserted into the pillar 552 of the assembly part 55, and finally the assembly part 55 is connected to the support 13. Then, the spring as the elastic member 53 is installed in the assembly hole 551 of the assembly part 55, and then the blocking member 51 is installed in the spring.

[0096] Install the damping sheet 71 into the mounting groove 315 of the bracket 30, and align the third through hole 711 of the damping sheet 71 with the first through hole 317 of the bracket 30. Clamp one end of the arc-shaped slider 3113 into the inner side of the snap hook 3116 of the bracket 30, and clamp the limiting ribs 3115 onto the two sides of the arc-shaped slider 3113, so that the arc-shaped slider 3113 is fixed into the assembly groove 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, and 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 then tighten with the nut 73. At this time, the bracket 30 and the support 13 are fixed together.

[0098] In the above-mentioned fuselage assembly 100, when the nose 201 is turned down, the arc-shaped slider 3113 in the bracket 30 presses against the bumper, and the bumper squeezes the spring. At this time, the bumper is separated from the positioning hole 3111, and the bracket 30 can be moved, so that the nose 201 can be folded and attached to the fuselage. When the nose 201 needs to be erected, the bracket 30 is lifted up, and the bumper is stuck in the positioning hole 3111, which can effectively lock the bracket 30 and fix the nose 201.

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

[0100] 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.

[0101] 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.
