DETAILED DESCRIPTION

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

In one embodiment of the present invention, the oscillating mechanism 10 includes a support frame 100, a mounting seat 200 and a rolling column 400. The support frame 100 is used to install the fan body; the support frame 100 is arranged on the mounting seat 200, and the rolling column 400 is arranged between the support frame 100 and the mounting seat 200.

[0041] See also Figure 2 and Figure 3 Specifically, the support frame 100 can swing around the rotation axis a relative to the mounting seat 200; and the mounting seat 200 is provided with a first support portion 210 on one side of the support frame 100, and the support frame 100 is provided with a second support portion 110 on one side of the mounting seat 200. The rolling cylinder 400 is provided between the first support portion 210 and the second support portion 110, so that the first support portion 210 and the second support portion 110 are respectively in contact with the non-edge of the rolling cylinder 400, and the rolling cylinder 400 can roll between the first support portion 210 and the second support portion 110.

[0042] When in use, the fan body is set on the support frame 100, and the support frame 100 is set on the mounting seat 200, and the support frame 100 is driven to swing around the rotation axis a relative to the mounting seat 200, thereby realizing the swing of the fan body set on the support frame 100 relative to the mounting seat 200 around the rotation axis a, and realizing the adjustment of the fan body air outlet angle. Since the rolling column 400 is set between the first support part 210 and the second support part 110, so that the first support part 210 and the second support part 110 are respectively abutted against the non-edge of the rolling column 400. Since during the processing, burrs and other defects are prone to appear at the edges of the rolling column 400, if the first support part 210 or the second support part 110 is in direct contact with the edges of the rolling column 400, burrs and other defects will affect the stability of the swing of the support frame 100 relative to the mounting seat 200 through the rolling column 400. By the first support part 210 and the second support part 110 respectively abutting against the non-edge of the rolling column 400, the first support part 210 and the second support part 110 can be effectively prevented from abutting against the edge, thereby ensuring stability during the swinging of the head.

[0043] In one embodiment, the mounting seat 200 is further provided with a first avoidance space 220 on one side facing the support frame 100, and the first avoidance space 220 and the first support portion 210 are arranged in a direction toward the rotation axis a, and the support frame 100 is further provided with a second avoidance space 120 that is relatively connected to the first avoidance space 220 in the direction of the rotation axis a on one side facing the mounting seat 200. The outer cylindrical surface of the rolling cylinder 400 is formed as a rolling surface 402, and the side edge of the rolling surface 402 is formed as an edge, the first support portion 210 and the second support portion 110 are respectively abutted on the rolling surface 402, and the edge of the rolling cylinder 400 is located in a space formed after the first avoidance space 220 and the second avoidance space 120 are connected. The first avoidance space 220 and the first support portion 210 are arranged along the radial direction of the mounting seat 200. Specifically, the first support portion 210 and the second support portion 110 are relatively arranged in the direction of the rotation axis a. By forming the connection between the first avoidance space 220 and the second avoidance space 120 , it is possible to effectively avoid the first support portion 210 and the second support portion 110 from abutting against the edges of the rolling surface 402 , thereby ensuring stability during the swinging of the head.

[0044] In this embodiment, the rolling cylinder 400 is disposed between the first supporting portion 210 and the second supporting portion 110 and can roll around the axis of the rolling cylinder 400 , and the axis of the rolling cylinder 400 intersects with the rotation axis a.

[0045] In one embodiment, one side of the rolling surface 402 is formed as an edge, the first support portion 210 is formed with the first avoidance space 220 on the side facing the rotation axis a, the second support portion 110 is formed with the second avoidance space 120 on the side facing the rotation axis a, the second avoidance space 120 is connected with the first avoidance space 220 correspondingly, and the two edges of the rolling cylinder 400 are located in the space formed after the first avoidance space 220 is connected with the second avoidance space 120.

[0046] In another embodiment, one side edge of the rolling surface 402 is formed as an edge, the first support portion 210 is formed with the first avoidance space 220 on the side facing away from the rotation axis a, the second support portion 110 is formed with the second avoidance space 120 on the side facing away from the rotation axis a, the second avoidance space 120 is connected with the first avoidance space 220 correspondingly, and the two edges of the rolling cylinder 400 are located in the space formed after the first avoidance space 220 is connected with the second avoidance space 120.

[0047] In this embodiment, the opposite side edges of the rolling surface 402 are respectively formed as edges, the first support portion 210 is respectively formed with the first avoidance space 220 on the side facing and facing away from the rotation axis a, and the second support portion 110 is respectively formed with the second avoidance space 120 on the side facing and facing away from the rotation axis a, each of the second avoidance spaces 120 can be connected with a corresponding first avoidance space 220, and the opposite edges of the rolling column 400 are respectively located in the space formed after the first avoidance space 220 is connected with the second avoidance space 120.

[0048] Specifically, the mounting seat 200 is provided with a first support member 230 on one side facing the support frame 100, and the first support member 230 is provided with a first avoidance groove on one side facing the support frame 100, and the first support portion 210 is provided in the first avoidance groove, and the first support portion 210 and the first avoidance groove have intervals between the two opposite inner side walls to form the first avoidance space 220. Since the first support portion 210 directly abuts against the rolling column 400, wear is generated between the first support portion 210 and the rolling column 400. By providing the first support member 230, it is not only convenient to form the first avoidance space 220, but also convenient to arrange the first support portion 210 on the first support member 230, so as to avoid wear on the mounting seat 200, and it is convenient to make the first support member 230 and the first support portion 210 made of wear-resistant materials.

[0049] See also Figure 4Further, the first support member 230 is an annular structure, the first avoidance groove is an annular groove, and the central axis of the annular groove is coaxially arranged with the rotation axis a, and the first support portion 210 is an annular protrusion arranged in the first avoidance groove. Since the first support portion 210 can abut against the rolling column 400, by setting the first support member 230 as an annular protrusion, the first support portion 210 is prevented from affecting the rolling of the rolling column 400.

[0050] In this embodiment, a placement groove 240 is provided on one side of the mounting seat 200 facing the support frame 100, and the first support member 230 is disposed in the placement groove 240. The placement groove 240 can provide an installation space for the first support member 230 to be disposed on the mounting seat 200. Optionally, the placement groove 240 is an annular groove.

[0051] See also Figure 2 and Figure 3 In one embodiment, a second support member is provided on one side of the support frame 100 facing the mounting seat 200, a second avoidance groove is provided on one side of the second support member facing the mounting seat 200, the second support portion 110 is provided in the second avoidance groove, and a gap is provided between the second support portion 110 and the two inner side walls of the second avoidance groove to form the second avoidance space 120. Since the second support portion 110 directly abuts against the rolling column 400, wear is caused between the second support portion 110 and the rolling column 400. By providing the second support member, it is not only convenient to form the second avoidance space 120, but also convenient to arrange the second support portion 110 on the second support member to avoid wear on the support frame 100, and it is convenient to make the second support member and the second support portion 110 of wear-resistant material.

[0052] Further, the second support member is an annular structure, the second avoidance groove is an annular groove, and the central axis of the annular groove is coaxially arranged with the rotation axis a, and the second support portion 110 is an annular protrusion arranged in the second avoidance groove. Since the second support portion 110 can abut against the rolling column 400, by setting the second support member as an annular protrusion, the second support portion 110 is prevented from affecting the rolling of the rolling column 400.

[0053] See also Figure 3 , Figure 5 and Figure 6In one embodiment, one of the rolling column 400 and the mounting seat 200 is provided with a positioning groove 250, and the other is provided with a roller 410, the axis direction of the roller 410 is toward the rotation axis a, the roller 410 is inserted into the positioning groove 250, and the roller 410 can rotate around the axis of the roller 410 in the positioning groove 250, and the positioning groove 250 is used to limit the displacement of the roller 410 around the rotation axis a. Since the positioning groove 250 can limit the displacement of the roller 410 around the rotation axis a, the rolling column 400 can be ensured to roll at a fixed position, avoiding the displacement of the rolling column 400 around the rotation axis a, and can further improve the stability of the swing of the support frame 100 relative to the mounting seat 200 through the rolling column 400.

[0054] In one embodiment, the mounting seat 200 is provided with a placement groove 240 on one side facing the support member, the first support portion 210 is provided on the bottom wall of the placement groove 240, and the positioning grooves 250 are respectively provided on the two opposite inner side walls of the placement groove 240. The rolling column 400 includes a rolling sleeve 420, the rolling sleeve 420 is sleeved on the roller 410, and the opposite ends of the roller 410 are respectively inserted into the two positioning grooves 250, and the outer surface of the rolling sleeve 420 forms the rolling surface 402. The provision of the rolling sleeve 420 facilitates the insertion of the roller 410, and further facilitates the limitation of the roller 410 in the direction around the rotation axis a.

[0055] In this embodiment, the outer surface of the rolling sleeve 420 is a cylindrical surface, and the surface of the first support portion 210 facing the rolling sleeve 420 and the surface of the second support portion 110 facing the rolling sleeve 420 both match the outer surface of the rolling sleeve 420, so as to improve the rolling stability of the rolling sleeve 420 between the first support portion 210 and the second support portion 110.

[0056] See also Figure 3 and Figure 5In one embodiment, the rolling column 400 further includes a limiting sleeve 430, the limiting sleeve 430 is sleeved on the roller 410, the rolling sleeve 420 is sleeved on the outer wall of the limiting sleeve 430, and the length of the limiting sleeve 430 along the axis direction of the roller 410 is greater than the length of the rolling sleeve 420 along the axis direction of the roller 410; the connection between the rolling sleeve 420 and the limiting sleeve 430 is located in the space formed after the first avoidance space 220 and the second avoidance space 120 are connected. When the roller 410 is inserted into the positioning groove 250, the limiting sleeve 430 can be limited in the placement groove 240. By setting the limiting sleeve 430, the displacement of the rolling column 400 in the direction close to or away from the rotation axis a can be limited. In other embodiments, the limiting sleeve 430 can also be omitted.

[0057] Optionally, the limiting sleeve 430 is clearance-fitted with the roller 410, and the limiting sleeve 430 is rotatable relative to the roller 410. Optionally, the limiting sleeve 430 can also be interference-fitted with the roller 410, and the limiting sleeve 430 is non-rotatable relative to the roller 410.

[0058] Specifically, at least two abutting protrusions 440 are arranged on the inner wall of the limiting sleeve 430, and different abutting protrusions 440 are arranged at intervals around the axis of the roller 410, and the abutting protrusions 440 can abut on the roller 410. Since the abutting protrusions 440 directly abut on the roller 410, the processing accuracy of the inner wall of the limiting sleeve 430 can be reduced, and it is only necessary to make the abutting protrusions 440 abut on the roller 410. In this embodiment, there are four abutting protrusions 440, and the four abutting protrusions 440 are evenly arranged around the roller 410. In other embodiments, the number of the abutting protrusions 440 can also be other numbers.

[0059] In other embodiments, the roller 410 is disposed on the inner wall of the placement groove 240 , and the inner annular surface of the rolling sleeve 420 surrounds the locking groove 250 , and the roller 410 can be inserted into the locking groove 250 .

[0060] Alternatively, in another embodiment, one of the rolling column 400 and the support frame 100 may be provided with a positioning groove 250, and the other may be provided with a roller 410, and the roller 410 may pass through the positioning groove 250. This allows the rolling column 400 to be limited on the support frame 100, and when the support frame 100 swings relative to the mounting seat 200, it can drive the rolling column 400 to swing synchronously relative to the mounting seat 200, thereby improving the flexibility of the swing of the support frame 100 relative to the mounting seat 200.

[0061] See also Figure 1 and Figure 2In one embodiment, the rolling cylinder 400 is multiple, and different rolling cylinders 400 are arranged between the mounting seat 200 and the support frame 100 at intervals around the rotation axis a. By providing multiple rolling cylinders 400, the swing stability of the support frame 100 relative to the mounting seat 200 can be further improved.

[0062] In one embodiment, the rolling cylinder 400 is an injection molded part, which facilitates the formation of the shape of the rolling cylinder 400. In other embodiments, the rolling cylinder 400 can also be other types of structural parts. In this embodiment, the rolling sleeve 420 is integrally formed on the limiting sleeve 430, that is, the rolling cylinder 400 is an integrally formed structure. In other embodiments, the rolling sleeve 420 and the limiting sleeve 430 can also be a split structure, and the rolling sleeve 420 is sleeved on the limiting sleeve 430.

[0063] See also Figure 2 , Figure 6 and Figure 7 In one embodiment, the support frame 100 is provided with a first rotating structure on one side facing the mounting seat 200, and the mounting seat 200 is provided with a second rotating structure on one side facing the support frame 100. The second rotating structure is rotationally matched with the first rotating structure, and the rotation axis a is the rotation axis a of the first rotating structure relative to the second rotating structure. By providing the rotational matching of the first rotating structure and the second rotating structure, the swing stability of the support frame 100 relative to the mounting seat 200 can be further improved.

[0064] For example, the first rotating structure is the rotating shaft 130, the second rotating structure is the rotating hole 260, the rotating shaft 130 is inserted into the rotating hole 260, and can rotate in the rotating hole 260. The axis of the rotating hole 260 is the rotating axis a of the support frame 100 swinging relative to the mounting seat 200. Alternatively, the first rotating structure is the rotating hole 260, and the second rotating structure is the rotating shaft 130.

[0065] See also Figure 6 , Figure 7 and Fig. 9 In one embodiment, the oscillating mechanism 10 further includes a sleeve 500, which is disposed in the rotating hole 260, and the rotating shaft 130 is passed through the sleeve 500. Since the rotating shaft 130 rotates in the rotating hole 260, the sleeve 500 is provided to prevent the rotating shaft 130 from directly contacting the inner wall of the rotating hole 260, thereby preventing the wear of the inner wall of the rotating hole 260. In this embodiment, the sleeve 500 can be made of a wear-resistant material.

[0066] Specifically, a limiting protrusion 510 is disposed on one of the outer wall of the sleeve 500 and an inner wall of the rotating hole 260, and a limiting groove is disposed on the other, the sleeve 500 is disposed in the rotating hole 260, so that the limiting protrusion 510 is disposed in the limiting groove, and the rotating shaft 130 is passed through the sleeve 500.
