AI Technical Summary
The traditional fan's rotating connection structure design results in a lack of robust sound, affecting consumers' judgment of the product's quality, and also leads to high production costs.
By designing structures such as an upper connecting mechanism, a lower connecting mechanism, an arc-shaped positioning component, a positioning protrusion, and a return spring, the sound output structure at the rotating connection is optimized, making the sound of the positioning protrusion striking the arc-shaped positioning component more resonant. The sound quality is enhanced through the sound outlet cavity of the through hole and the sound outlet groove of the rotating mechanism.
This resulted in a richer, more resonant sound from the fan, enhancing the product's acoustic experience while simultaneously reducing production costs.

[0023] It should be understood that the specific embodiments described herein are merely intended to explain the utility model, and are not used to limit the utility model.
[0024] Referring to Figures 1 to 5 , an embodiment of the connecting structure for the rotating sound of the fan is proposed:
[0025] A connecting structure for the rotating sound of the fan is more full-bodied and has a good quality feeling, which comprises an upper connecting mechanism 1 arranged at the bottom of a fan body, a lower connecting mechanism 2 arranged at the top of a supporting rod, a rotating elastic sheet, an arc-shaped positioning piece 3, a positioning protrusion 4, an outer connecting piece and a reset spring 5.
[0026] A connecting mechanism connecting groove 11 is respectively provided on both sides of the side of the upper connecting mechanism 11, and a connecting mechanism rotating column is provided in the connecting mechanism connecting groove 11. An upper rotating connecting hole 12 is provided through the connecting mechanism rotating column. A lower rotating connecting hole 21 is provided on the side of the lower connecting mechanism 2. The upper rotating connecting hole 11 and the lower rotating connecting hole 21 are connected by studs, so that the upper connecting mechanism 1 is rotatably connected to the top of the lower connecting mechanism 2.
[0027] A circle of connecting grooves 13 is provided on the inner bottom of one side of the connecting mechanism connecting groove 11, surrounding the connecting mechanism rotating column. A rotating spring is pressed against the connecting groove 13 and sandwiched between the upper connecting mechanism 1 and the lower connecting mechanism 2. The provision of the rotating spring ensures that the upper connecting mechanism 1 has a damping effect when rotating compared to the lower connecting mechanism 2. Multiple rotating mechanism sound emitting grooves 14 are provided on the side of the connecting mechanism connecting groove 11 without the connecting groove 13. These rotating mechanism sound emitting grooves 14 ensure that the sound produced by the upper connecting mechanism 1 is richer than that produced by the lower connecting mechanism 2 when rotating.
[0028] The bottom of the upper connecting mechanism 1 is provided with a connecting mechanism positioning groove 15, which has an arc-shaped opening at the bottom. The arc-shaped positioning member 3 is disposed within the connecting mechanism positioning groove 15, and the arc-shaped positioning member 3 is provided with a positioning member positioning hole 31. The top of the lower connecting mechanism 2 is provided with a lower connecting mechanism positioning hole 22, and the positioning protrusion 4 and the return spring 5 are retained in the lower connecting mechanism positioning hole 22. The bottom of the lower connecting mechanism positioning hole 22 is provided with an external connecting hole. One end of the external connecting member passes through the external connecting hole and connects to the bottom of the positioning protrusion 4, which is used to limit the positioning protrusion 4. The positioning protrusion 4 cooperates with the positioning member positioning hole 31 to determine the rotation angle of the upper connecting mechanism 1 relative to the lower connecting mechanism 2.
[0029] A wire hole 16 is also provided at the bottom of the upper connecting mechanism 1. The external line passes through the wire hole 16 from the lower connecting mechanism 2 into the upper connecting mechanism 1. The wire hole 16 is open on the side, and one side of the wire hole 16 extends toward the opening to form a surrounding edge 17, and a wire hole sound cavity 18 is formed through the surrounding edge 17. The wire hole sound cavity 18 can make the sound of the positioning protrusion 4 hitting the arc-shaped positioning member 3 thicker and more textured.
