[0058] Referring to Figure 5 Figure 5 Figure 7 Figure 5 In one embodiment of the present application, the connecting shaft 50 comprises a bearing structure 51 and a shaft body 53, the shaft body 53 penetrates the mounting base 11 and the support web plate, and the bearing structure 51 is connected to the mounting base 11 and / or the support web plate and is sleeved on the outer periphery of the shaft body 53.

[0059] It can be understood that the connecting shaft 50 can include a shaft body 53 penetrating the mounting seat 11 and the support web 31, and a bearing structure 51 sleeved on the outer periphery of the shaft body 53. Under the action of the bearing structure 51, the shaft body 53 can rotate more smoothly, reducing the friction when the shaft body 53 rotates. Further, a through hole can be provided on the side wall of the mounting seat 11, and the bearing structure 51 is installed and fixed in the through hole, so that the shaft body 53 can pass through the bearing structure 51 on the mounting seat 11 to connect the support web 31. At this time, the end of the connecting shaft 50 can be connected by a check ring and abut against the side wall of the support web 31 facing away from the mounting seat 11, achieving stable installation of the connecting shaft 50. Alternatively, a through hole can be provided on the side wall of the support web 31, and the bearing structure 51 is installed and fixed in the through hole, and the mounting seat 11 is provided with a corresponding bearing hole, so that the shaft body 53 can pass through the bearing structure 51 and the bearing hole to connect the mounting seat 11 and the support web 31.

[0060] In addition, when the mounting seat 11 or the support web 31 is provided in a sheet metal plate structure, the bearing structure 51 can further include a bearing seat and a bearing body. The bearing seat can be clamped and installed on the mounting seat 11 or the support web 31, and the bearing body is installed and fixed in the bearing seat, so that the bearing structure 51 can be more stably and reliably connected and installed on the mounting seat 11 or the support web 31, avoiding the possibility that the bearing cannot be well installed due to the too small thickness of the mounting seat 11 or the support web 31, without the need for the mounting seat 11 and the support web 31 to adopt a more complex structure design to increase production costs, further improving the practicality and structural reliability of the swing assembly 100.

[0061] In an embodiment of the present application, the first mounting member 10 comprises a first connecting column, a second connecting column and a turning mechanism, the second connecting column is stacked with the first connecting column, and the end of the second connecting column facing away from the first connecting column is provided with the mounting seat 11; the turning mechanism connects the first connecting column and the second connecting column, and drives the second connecting column to rotate relative to the first connecting column.

[0062] In the embodiment, the first mounting member 10 can be formed by a first connecting column and a second connecting column which are stacked with each other and can be sleeve structures with cavities, so that the steering mechanism can be mounted in the inner cavities of the first connecting column and the second connecting column and connect the first connecting column and the second connecting column, by connecting and fixing the first connecting column with the support 500, the steering mechanism can be driven to operate by electricity, so that the second connecting column is driven to rotate horizontally relative to the first connecting column, that is, the second connecting column can be rotated in the left-right direction. Further, by arranging the mounting seat 11 on the end of the second connecting column which is away from the first connecting column, the second mounting member 30 can be driven to rotate together with the second connecting column when the second connecting column rotates, the horizontal swing function of the swing assembly 100 is realized, so that the fan 1000 can realize a larger blowing effect, and the practicability and reliability of the swing assembly 100 are further improved. By arranging the steering mechanism in the first mounting member 10 to drive the second connecting column to rotate, and driving the second mounting member 30 to rotate horizontally by the second connecting column, the swing assembly 100 can integrate the up-down swinging function and the horizontal swinging function, and further can realize the swinging action of multiple degrees of freedom, effectively improve the blowing range of the fan 1000, so that the fan 1000 can better meet the use demand of the user, and the practicability and reliability of the swing assembly 100 are further improved. By integrating the horizontal head driving part on the first mounting member 10 of the swing assembly 100, and arranging the driving member 70 between the first mounting member 10 and the second mounting member 30 to realize the up-down head function, the swing assembly 100 can more compactly arrange multiple driving parts in a smaller volume setting, which is beneficial to better realize the miniaturization design of the swing assembly 100, and further can better reduce the overall volume of the fan 1000, and further improve the practicability of the swing assembly 100.

[0063] In an embodiment of the utility model, the mounting seat 11 is equipped with first limit structure, the support web 31 is equipped with second limit structure, first limit structure with second limit structure can cooperate abut, in order to limit the rotation angle of support web 31 relative mounting seat 11.

[0064] In the embodiment, the mounting seat 11 can be provided with a first limiting structure on the side facing the support web plate 31, and a second limiting structure on the side of the support web plate 31 facing the mounting seat 11. The first limiting structure and the second limiting structure can be a boss structure, or can be a structure of a protrusion and a groove matched with each other. Of course, the first limiting structure and the second limiting structure can also adopt other structures matched with each other, and the application does not limit the structure form of the first limiting structure and the second limiting structure, as long as the first limiting structure and the second limiting structure can be matched and abutted when the support web plate 31 rotates relative to the mounting seat 11 by a certain angle. When the support web plate 31 rotates relative to the mounting seat 11 by a certain angle around the connecting shaft 50, the first limiting structure and the second limiting structure can abut against each other, thereby limiting the rotation angle of the support web plate 31, effectively preventing the second mounting part 30 from rotating by too large an angle relative to the first mounting part 10, which has a certain probability of causing the components in the swing assembly 100 to collide with each other. For example, the transmission gear 71 of the driving part 70 can be prevented from colliding with the end of the transmission rack 313, or the first mounting part 10 and the second mounting part 30 can be prevented from colliding with each other, so that the swing assembly 100 can operate more stably and reliably.

[0065] In order to achieve a better swing angle of the fan 1000, the first limiting structure and the second limiting structure can abut against each other when the support web plate 31 rotates to drive the head assembly 300 to blow horizontally, and can abut against each other when the support web plate 31 rotates to drive the head assembly 300 to blow vertically upward, so that the fan 1000 can cover a larger blowing range. Of course, under the condition of meeting the mutual avoidance of the components of the fan 1000, the swing assembly 100 can make the first limiting structure and the second limiting structure abut against each other when the support web plate 31 rotates by a larger angle, so that the fan 1000 can better meet the use requirements. The application does not limit the rotation range of the support web plate 31 limited by the first limiting structure and the second limiting structure.

[0066] The utility model also proposes a fan 1000, this fan 1000 includes head assembly 300 and swing assembly 100, the specific structure of this swing assembly 100 refers to the above -mentioned embodiment, because the fan 1000 of this adopts all the technical schemes of the above -mentioned embodiment, therefore at least has all the beneficial effects brought by the technical scheme of the above -mentioned embodiment, here will not repeat again.
