[0044] See also Figure 1 , Figure 2 and Figure 3 An embodiment of the present application provides an oscillating mechanism, which includes a head bracket 100, a rotating shaft 200, a fixing seat 400 and a driving member 300.

[0045] The rotating shaft 200 is fixed to the head bracket 100. The fixing seat 400 is detachably connected to the rotating shaft 200, and the driving member 300 is arranged on the fixing seat 400. The driving end of the driving member 300 is connected to the rotating shaft 200 to drive the rotating shaft 200 to rotate relative to the fixing seat 400.

[0046] It should be noted that, in the present application, the head bracket 100 can be understood as a structure in the fan for fixing and supporting the fan head assembly, and its specific structure and shape are not limited. The fixing seat 400 can be understood as a structure in the fan for fixing and supporting the body assembly of the fan. The shape and structure of the rotating shaft 200 are not limited, and are preferably a regular rotating body structure, such as a cylinder.

[0047] See also Figure 2 , along the direction from top to bottom, the head bracket 100 , the rotating shaft 200 and the fixing seat 400 are distributed in sequence, that is, the rotating shaft 200 is located between the head bracket 100 and the fixing seat 400 .

[0048] The rotating shaft 200 can be fixedly connected to the head bracket 100 by fasteners such as screws and bolts. The detachable connection method between the rotating shaft 200 and the fixing seat 400 can be but not limited to plug-in and snap-in, so that the rotating shaft 200 can rotate relative to the fixing seat 400 under the driving action of the driving member 300. At the same time, the fixing seat 400 can also form axial and radial limits on the rotating shaft 200, thereby reducing the probability of radial and axial deviation of the rotating shaft 200, so that the rotating shaft 200 only has rotational freedom, thereby improving the movement stability of the rotating shaft 200 and the head bracket 100.

[0049] An installation cavity for accommodating the driving member 300 may be provided in the fixing seat 400 to reduce the installation space of the driving member 300 and improve the overall space utilization of the shaking mechanism.

[0050] In the present application, the driving member 300 may be, but is not limited to, a rotating driving member such as an electric motor or the like, and no specific limitation is made.

[0051] It is easy to understand that when the shaking head mechanism of the present application performs shaking head movement, the fixed seat 400 provides installation support for the driving member 300, and the driving end of the driving member 300 drives the rotating shaft 200 to rotate relative to the fixed seat 400. During this process, the fixed seat 400 remains stationary, and the rotating shaft 200 drives the head bracket 100 thereon to rotate synchronously, thereby realizing the shaking head function.

[0052] It is not difficult to understand that the shaking head mechanism of the present application, by setting the driving member 300 on the fixed seat 400, provides a stable installation support structure for the driving member 300 through the fixed seat 400; by connecting the driving end of the driving member 300 to the rotating shaft 200, and fixing the rotating shaft 200 on the head bracket 100, so that the driving end of the driving member 300 is connected to the head bracket 100 through the rotating shaft 200, when the driving member 300 drives the rotating shaft 200 to rotate relative to the fixed seat 400, the rotating shaft 200 can drive the head bracket 100 to rotate synchronously, thereby realizing the shaking head function.

[0053] The shaking head mechanism of the present application effectively simplifies the structural components and driving structure of the shaking head mechanism through the coordinated arrangement of the head bracket 100, the rotating shaft 200, the fixing seat 400 and the driving member 300, effectively reduces the probability of the shaking head being unsmooth or stuck due to the wear between the various structural components on the shaking head mechanism, improves the smoothness and stability of the shaking head movement of the shaking head mechanism, and also reduces the overall production cost of the shaking head mechanism.

[0054] In some embodiments of the present application, see Figure 3 , Figure 4 and Figure 5 The driving member 300 has a driving shaft 310 , and the rotating shaft 200 is provided with a first plug interface 210 , and the driving shaft 310 is plugged and matched with the first plug interface 210 .

[0055] Specifically, the driving member 300 is a driving motor, and the driving shaft 310 is the rotating shaft of the driving motor. The driving shaft 310 can be but is not limited to a circular shaft, a square shaft, or a diagonal shaft. Correspondingly, the first plug interface 210 can be but is not limited to a circular hole, a square hole, a polygonal hole, etc., so that the driving shaft 310 and the first plug interface 210 form a stable plug-in fit.

[0056] Of course, in order to further improve the stability of the plug-in fit between the drive shaft 310 and the first plug-in port 210 , the drive shaft 310 and the first plug-in port 210 are preferably in an interference fit.

[0057] It is not difficult to understand that the shaking mechanism of the present application can improve the convenience of connecting the driving member 300 with the rotating shaft 200 by making the driving shaft 310 of the driving member 300 plug and match with the first plug interface 210.

[0058] In some embodiments of the present application, see Figure 2 , Figure 5 and Figure 6 The rotating shaft 200 is provided with a second plug-in port 220 , and the fixing seat 400 is provided with a positioning portion 410 , and the positioning portion 410 is plugged and matched with the second plug-in port 220 .

[0059] Specifically, the fixing seat 400 is an annular structure, and the positioning portion 410 is a hollow column arranged at the center of the fixing seat 400, that is, the positioning portion 410 coincides with the axis of the fixing seat 400. Correspondingly, the rotating shaft 200 has an annular cavity, and the axis of the annular cavity coincides with the axis of the positioning portion 410.

[0060] Such arrangement enables the positioning portion 410 on the fixed seat 400 to form a coaxial plug-in fit with the second plug interface 220 on the rotating shaft 200, which facilitates the disassembly and assembly of the fixed seat 400 and the rotating shaft 200, while effectively ensuring that the rotating shaft 200 rotates relative to the fixed seat 400 under the action of the driving member 300, and enables the fixed seat 400 to form a good limit in the axial and radial directions of the rotating shaft 200, thereby improving the stability of the rotational motion of the rotating shaft 200 and the head bracket 100, thereby improving the stability and smoothness of the overall shaking function of the shaking mechanism.

[0061] In some embodiments of the present application, see 3. Figure 5 and Figure 6 The rotating shaft 200 is provided with a locking portion 230 , and the fixing seat 400 is provided with a locking groove 420 . The locking portion 230 is engaged with the locking groove 420 and can rotate along the locking groove 420 .

[0062] Specifically, the locking portion 230 is a buckle provided on the outer wall of the rotating shaft 200, and the engaging groove 420 is an annular groove provided on the outer wall of the fixing seat 400, and the axis of the annular groove coincides with the axis of the rotating shaft 200. The locking portion 230 is slidably engaged in the engaging groove 420. In this way, when the rotating shaft 200 rotates under the driving action of the driving member 300, the locking portion 230 on the rotating shaft 200 slides along the circumferential track of the engaging groove 420 synchronously.

[0063] It is not difficult to understand that, through the snap-fitting cooperation between the locking portion 230 on the rotating shaft 200 and the locking groove 420 on the fixing seat 400, on the one hand, the locking groove 420 on the fixing seat 400 forms an axial stop limit for the locking portion 230 on the rotating shaft 200, thereby preventing the rotating shaft 200 from deviating or detaching from the fixing seat 400 during rotation, thereby causing the head bracket 100 and the fan head assembly thereon to be dislocated, and further, it can prevent the rotating shaft 200 from driving the fixing seat 400 to rotate, thereby improving the accuracy of the rotating shaft 200's rotational movement and making the head bracket 100 and the fan head assembly thereon have a more accurate shaking angle.

[0064] In addition, it should be noted that there can be multiple locking parts 230, and the multiple locking parts 230 are distributed in the annular locking groove 420 at intervals along the circumference. In this way, the stability of the movement of the rotating shaft 200 is further improved, and the stability and smoothness of the overall shaking function of the shaking mechanism are further improved.

[0065] In some embodiments of the present application, see 3. Figure 5 and Figure 6At least two stop parts 430 are circumferentially provided on the fixing seat 400, and the outer wall of the rotating shaft 200 is provided with a limiting part 240 that can cooperate with the stopping part 430, and the limiting part 240 is located between the two stopping parts 430 so as to limit the rotation angle by the two stopping parts 430.

[0066] Specifically, the fixing seat 400 has an annular limiting groove, the stopper 430 is a convex block arranged on the annular limiting groove, and at least two convex blocks are spaced apart and distributed in the annular limiting groove. Correspondingly, the limiting portion 240 is a boss arranged on the outer wall of the rotating shaft 200 .

[0067] It should be understood that when the rotating shaft 200 rotates under the drive of the driving member 300 to drive the head bracket 100 and the fan head assembly thereon to swing, the limiting portion 240 on the rotating shaft 200 rotates synchronously along the annular limiting groove on the fixing seat 400. When the limiting portion 240 on the rotating shaft 200 rotates to abut against the stopper 430 on the annular limiting groove and is stopped and limited by the stopper 430, at this time, the rotating shaft 200 rotates to a limit angle, that is, the head bracket 100 and the fan head assembly thereon swing to a limit position, at this time, the driving member 300 stops driving the rotating shaft 200 to rotate, or the driving member 300 drives the rotating shaft 200 to rotate in a direction opposite to the initial rotation direction.

[0068] Similarly, when the limiting portion 240 on the rotating shaft 200 rotates to abut against another stop portion 430 on the annular limiting groove and is stopped and limited by the stop portion 430, it indicates that the rotating shaft 200 has rotated to another extreme angle, that is, the head bracket 100 and the fan head assembly thereon have swung to another extreme position. At this time, the driving member 300 stops driving the rotating shaft 200 to rotate, or the driving member 300 drives the rotating shaft 200 to rotate in a direction opposite to the initial rotation direction.

[0069] It is not difficult to understand that the coordinated arrangement of the multiple stop portions 430 on the fixed base 400 and the limiting portions 240 on the rotating shaft 200 can effectively limit the maximum rotation angle of the rotating shaft 200, thereby preventing the rotating shaft 200 from driving the head bracket 100 and the fan head assembly thereon to rotate at an angle exceeding the maximum limited angle and causing structural damage, thereby further improving the stability and smoothness of the overall shaking function of the shaking mechanism.

[0070] In some embodiments of the present application, see Figure 2 , Figure 4 and Figure 7 The driving member 300 is provided with a plurality of first connecting parts 320 , and the fixing seat 400 is provided with a second connecting part 440 aligned with the first connecting part 320 . The first connecting part 320 is detachably connected to the second connecting part 440 via a first fastener 330 .

[0071] Specifically, the first connecting portion 320 on the driving member 300 is constructed as a threaded connecting hole, the second connecting portion 440 on the fixing seat 400 is constructed as a screw column hole, and the first fastener 330 is constructed as a screw column. The screw column threadably connects the threaded connecting hole on the driving member 300 with the screw column hole on the fixing seat 400 from bottom to top, thereby removably fixing the driving member 300 on the fixing seat 400, making it convenient for disassembly, maintenance and replacement of the driving member 300.

[0072] In some embodiments of the present application, see Figure 2 and Figure 5 The rotating shaft 200 is provided with a plurality of third connecting parts 250 , the head bracket 100 is provided with a fourth connecting part 110 aligned with the third connecting part 250 , and the third connecting part 250 is detachably connected to the fourth connecting part 110 via a second fastener 260 .

[0073] Specifically, the third connecting part 250 is constructed as a threaded connection hole, the fourth connecting part 110 is constructed as a screw column hole, and the second fastener 260 is also constructed as a screw column. The screw column threadably connects the threaded connection hole on the rotating shaft 200 with the screw column hole on the head bracket 100 from bottom to top, thereby removably fixing the rotating shaft 200 on the head bracket 100. In this way, it is convenient to disassemble, repair and replace the rotating shaft 200, and it is also convenient to assemble and fix the head bracket 100 and the rotating shaft 200.

[0074] In addition, see Figure 1 and Figure 7 The embodiment of the present application further provides a fan, which includes the shaking mechanism described in any of the above embodiments, a fan head assembly (not shown in the figure) and a body assembly 500. The fan head assembly is installed on the head bracket 100, and the body assembly 500 is detachably connected to the fixing seat 400.

[0075] It should be noted that the fan of the present application may be, but is not limited to, a circulation fan, a floor fan or other fan structures.

[0076] The fan head assembly of the fan can be installed on the head bracket 100 in an interference fit manner to facilitate subsequent disassembly and replacement of the fan head assembly. The body assembly 500 refers to a structure that provides load bearing and support for the rest of the fan structure, and has a certain structural strength and hardness.

[0077] It is not difficult to understand that the fan of the present application, since it is equipped with the above-mentioned shaking head mechanism, also has the same technical effect brought by the shaking head mechanism, that is, through the coordinated arrangement of the head bracket 100, the rotating shaft 200, the fixing seat 400 and the driving member 300, the structural components and driving structure of the shaking head mechanism are effectively simplified, and the probability of smooth shaking or jamming caused by wear between the various structural components on the shaking head mechanism is effectively reduced, the smoothness and stability of the shaking head movement of the shaking head mechanism are improved, and the production cost of the shaking head mechanism and the fan as a whole is reduced.

[0078] In some embodiments of the present application, see Figure 7 and Figure 8 The fixing seat 400 is provided with a plurality of fifth connecting parts 450 , the fuselage assembly 500 is provided with a sixth connecting part 510 aligned with the fifth connecting part 450 , and the fifth connecting part 450 is detachably connected to the sixth connecting part 510 via a third fastener 460 .

[0079] Specifically, the fifth connection part 450 on the fixing base 400 is a threaded connection hole, the sixth connection part 510 on the body assembly 500 is a screw column hole, and the third fastener 460 is a screw column, which threadedly connects the threaded connection hole on the fixing base 400 with the screw column hole on the body assembly 500 from top to bottom, so that the fixing base 400 can be detachably installed on the body assembly 500 of the fan, thereby improving the convenience of disassembly and assembly of each component structure on the entire fan and improving the production efficiency of the fan.

[0080] Further, see Figure 8 The fuselage assembly 500 includes a fuselage seat 520 and a fuselage 530 , and the fuselage seat 520 is threadedly connected to the fuselage 530 .

[0081] Specifically, the fuselage 530 is constructed as a columnar structure, and an internal threaded hole is opened along the extension direction of the fuselage 530. The fuselage seat 520 has an external thread that matches the internal threaded hole. In this way, the fuselage seat 520 and the fuselage 530 form a threaded connection, which facilitates the assembly of the fuselage seat 520 and the fuselage 530 of the fan, and further improves the convenience of disassembly and assembly of the various component structures on the entire fan.

[0082] 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.

[0083] 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.
