DETAILED DESCRIPTION

[0030] 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.

[0031] like Figure 1 and Figure 2 As shown, in one embodiment, a fan oscillating assembly 10 is provided, including a bracket 11, a main motor 12, an oscillating motor 13, a circuit board 14 and an electrical assembly 15. Figure 3 As shown, the bracket 11 encloses an installation cavity 111 with an opening. The oscillating motor 13 and the electrical component 15 are both located in the installation cavity 111. The circuit board 14 is disposed at the position with the opening on the bracket 11. The main motor 12 is connected to the front of the bracket 11.

[0032] The above scheme provides a fan oscillating assembly 10, which uses the bracket 11 to carry the main motor 12, the oscillating motor 13, the circuit board 14 and the electrical component 15. Specifically, the oscillating motor 13 and the electrical component 15 are installed in the installation cavity 111, the circuit board 14 is arranged at the opening of the installation cavity 111, and the main motor 12 is connected to the front of the bracket 11. Thereby, the integration of the fan oscillating assembly 10 is improved, and the assembly efficiency is improved.

[0033] Specifically, Figure 1As shown, in one embodiment, the electrical component 15 and the oscillating motor 13 are sequentially arranged along the left-right direction in the installation cavity 111. The back of the main motor 12 away from the fan blades is connected to the bracket 11.

[0034] More specifically, if Figure 1 and Figure 3 As shown, the rear side wall 113 of the installation cavity 111 is provided with a plug hole 1131 , and the electrical component 15 is installed in the installation cavity 111 through the plug hole 1131 .

[0035] like Figure 1 , Figure 2 and Fig. 9 As shown, the electrical component 15 is provided with an auxiliary protrusion 151 protruding to the side. The auxiliary protrusion 151 is located behind the rear side wall 113, and the auxiliary protrusion 151 is in conflict with the rear side wall 113. The auxiliary protrusion 151 is provided with a second through hole 1511, and the bracket 11 is provided with a first limiting column passing through the second through hole 1511. The fan shaking assembly 10 also includes a fastener 16, which is detachably connected to the first limiting column and is used to limit the auxiliary protrusion 151 on the first limiting column.

[0036] Specifically, the first limiting column is provided with an external thread. The fastener 16 includes a knob, such as Figure 1 As shown, the knob is screwed on the first limiting column to limit the auxiliary protrusion 151 on the first limiting column.

[0037] During installation, the electrical component 15 is first inserted into the installation cavity 111 from the insertion hole 1131, and the first limiting column passes through the second through hole 1511. Then the knob is screwed onto the first limiting column to fix the electrical component 15 on the bracket 11.

[0038] Optionally, the fastener 16 may also be a snap-fit ​​piece, and the fastener 16 is detachably connected to the first limiting column by snapping.

[0039] Further, in one embodiment, if Figure 3 and Figure 4 As shown, the front side wall 112 of the installation cavity 111 is provided with a first through hole 1121. Figure 6 As shown, a fixing hole 121 is provided on the back of the main motor 12 away from the fan blades. The fan oscillating assembly 10 also includes a first connecting member, which passes through the first through hole 1121 and the fixing hole 121 in sequence to connect the bracket 11 and the main motor 12. Figure 1 As shown, the main motor 12 is suspended in front of the bracket 11 .

[0040] Further, in one embodiment, if Figure 1 As shown, the main shaft 122 of the main motor 12 is arranged in the front-to-back direction; the rotating shaft of the oscillating motor 13 is arranged in the longitudinal direction. The crank of the oscillating motor 13 is rotatably connected with the connecting rod rotatably arranged on the electric fan connector, so that when the oscillating motor 13 is running, the fan oscillating assembly 10 rotates relative to the connector, so that the fan blades on the main shaft 122 of the main motor 12 swing relative to the connector.

[0041] Further, in one embodiment, if Figures 1 to 3 As shown, the bracket 11 further includes a first blocking arm 115 extending in front of the front side wall 112 of the mounting cavity 111. The first blocking arm 115 is spaced apart from the outer circumference of the main motor 12 to form a first wiring gap. There are a plurality of first blocking arms 115, and the plurality of first blocking arms 115 are spaced apart along the circumference of the outer circumference of the main motor 12.

[0042] like Figure 3 As shown, the front side wall 112 of the installation cavity 111 refers to the side wall of the installation cavity 111 that is close to the main motor 12 and connected to the main motor 12. The front of the front side wall 112 refers to the direction of the front side wall 112 facing the main motor 12. The main motor 12, the oscillating motor 13, the circuit board 14 and the electrical components 15 need to be electrically connected to each other, so that Figure 1 and Figure 2 As shown, the fan oscillating assembly 10 needs to arrange multiple lines 20. Multiple lines 20 pass through each of the first wiring gaps and are arranged in order along the circumference of the main motor 12. The efficiency of arranging the lines 20 of the fan oscillating assembly 10 during assembly is further improved.

[0043] Further, in one embodiment, if Figure 3 and Figure 4 As shown, a wire-holding notch 1122 is provided on the front side wall 112 of the installation cavity 111 . The opening of the wire-holding notch 1122 is located on the outer circumferential surface of the front side wall 112 , and an elastic blocking arm 1123 is provided at the opening of the wire-holding notch 1122 to cover the opening.

[0044] like Figure 1As shown, multiple lines 20 are gathered under the bracket 11, and the line 20 that needs to be connected to the circuit board 14 and the main motor 12 moves forward along the first wiring gap, and finally squeezes the elastic blocking arm 1123 from the opening of the line clamping notch 1122, so that the line 20 is clamped in the line clamping notch 1122. After passing through the line clamping notch 1122, the line 20 is connected to the circuit board 14 or the main motor 12. The line clamping notch 1122 has a certain limiting effect on the line 20, so that the line 20 changes from the original direction arranged along the circumference of the main motor 12 to the direction arranged along the lateral direction, and then passes into the installation cavity 111.

[0045] Specifically, Figure 3 and Figure 4 As shown, in one embodiment, there are two wire-holding notches 1122 , and the two wire-holding notches 1122 are symmetrically distributed left and right with the longitudinal section passing through the axis of the main shaft 122 of the main motor 12 as a symmetry plane.

[0046] Further, in one embodiment, if Figure 3 As shown, the bracket 11 includes a baffle 116 that blocks the left and right sides of the circuit board 14. A support plate 117 suspended outside the baffle 116 is provided on the outer side of the baffle 116, and a second baffle arm 118 is provided on the support plate 117. The second baffle arm 118 is spaced apart from the baffle 116 to form a second wiring gap 1181. There are multiple second baffle arms 118, and the multiple second baffle arms 118 are sequentially spaced and arranged on the support plate 117 along the front-to-back direction.

[0047] like Figure 1 As shown, part of the circuit 20 that needs to be connected to the circuit board 14 passes through each of the second wiring gaps 1181 in the front-to-back direction. The plurality of second wiring gaps 1181 provide guidance for the forward movement of the circuit 20, thereby improving the convenience of arranging the circuit 20. This further improves the assembly efficiency and also makes the fan shaking assembly 10 more concise as a whole after assembly.

[0048] Further, in one embodiment, if Figure 4 As shown, a wiring hole 119 is provided in the side wall of the installation cavity 111 near the electrical component 15. Specifically, when the electrical component 15 and the oscillating motor 13 are arranged in sequence along the left and right directions in the installation cavity 111, the wiring hole 119 is provided on the side wall of the left and right side walls of the installation cavity 111 near the electrical component 15.

[0049] Since the oscillating motor 13 and the electrical component 15 are both arranged in the installation cavity 111, and the circuit board 14 shields the opening of the installation cavity 111, the line 20 that needs to pass through the installation cavity 111 and is connected to the oscillating motor 13 or the electrical component 15 enters from the wiring hole 119. Moreover, the oscillating motor 13 and the electrical component 15 are arranged in sequence in the left and right directions in the installation cavity 111, and the wiring hole 119 is arranged on the side wall of the left and right side walls of the installation cavity 111 close to the electrical component 15, so that the line 20 can be more easily connected to the electrical component 15.

[0050] More specifically, if Figure 3 As shown, in one embodiment, the opening on the bracket 11 is provided with a supporting rib 1111, and the supporting rib 1111 is multiple, and the multiple supporting ribs 1111 are arranged at intervals, and are used to support and limit the circuit board 14 on the bracket 11. The specific arrangement positions of the multiple supporting ribs 1111 can be set according to the shape of the circuit board 14.

[0051] Furthermore, in one embodiment, buttons are provided on the top surface of the circuit board 14 away from the mounting cavity 111. Therefore, during use, the buttons can be directly operated on the top of the electric fan head to adjust the electric fan.

[0052] Further, in one embodiment, if Figures 1 to 3 As shown, a plurality of the support ribs 1111 are arranged at the left and right edges of the circuit board 14. Figure 7 As shown, a third through hole 141 and a first limiting hole 142 are provided at the rear edge of the circuit board 14. Figure 3 As shown, a support column 1112 is provided at a position on the bracket 11 corresponding to the third through hole 141, and a threaded hole is provided in the support column 1112. The fan oscillating assembly 10 also includes a second connecting member, which passes through the third through hole 141 and is threadedly engaged with the support column 1112. Figure 3 As shown, a second limiting column 1113 is provided at a position on the bracket 11 corresponding to the first limiting hole 142 , and the second limiting column 1113 is inserted into the first limiting hole 142 , so that the circuit board 14 is finally fixed on the bracket 11 .

[0053] Further, in one embodiment, if Figure 8 As shown, the oscillating motor 13 is provided with a fourth through hole 131 and a second limiting hole 132. The fan oscillating assembly 10 further includes a third connecting member, which passes through the fourth through hole 131 and is connected to the bottom wall 114 of the installation cavity 111. Figure 5As shown, a third limiting column 1141 is provided on the bottom wall 114 of the installation cavity 111, and the third limiting column 1141 is inserted into the second limiting hole 132. Thus, the oscillating motor 13 is fixed in the installation cavity 111. When the oscillating motor 13 is in operation, the bracket 11 follows the oscillating motor 13 and swings relative to the connector. Then, the main motor 12, the circuit board 14 and the electrical components 15 connected to the bracket 11 all swing along.

[0054] Furthermore, if Figure 5 As shown, a clearance opening 1142 is provided on the bottom wall 114 of the installation cavity 111 at a position corresponding to the rotating shaft of the oscillating motor 13. The crank of the oscillating motor 13 extends out of the bracket 11 through the clearance opening 1142 and is rotatably connected with the connecting rod.

[0055] Furthermore, in another embodiment, an electric fan is provided, comprising the above-mentioned fan shaking head assembly 10.

[0056] The above scheme provides an electric fan, which integrates the main motor 12, the oscillating motor 13, the circuit board 14 and the electrical component 15 on the bracket 11 by adopting the fan oscillating assembly 10 described in any of the above embodiments, thereby improving the assembly efficiency.
