[0028] The present utility model provides a rotating high - pitched horn.
[0029] In the embodiments of the present utility model, as Figures 1 to 4As shown in the figure, the rotating tweeter includes a driving device 1, a rotating component 2, a decorative component 3, and a tweeter 4. Among them, the driving device 1 includes a stepper motor 11, a pinion 12, and a rotating large gear 13. The stepper motor 11 drives the rotating large gear 13 to rotate through the pinion 12, and the pinion 12 meshes with the external teeth of the rotating large gear 13;
[0030] The rotating component 2 includes a rotating main body bracket 21, a rotating main body lower cover plate 22, and a rotating rising fixed bracket 23. The rotating main body lower cover plate 22 is fixedly installed on the rotating main body bracket 21;
[0031] The decorative component 3 is connected to the rotating large gear 13;
[0032] The tweeter 4 is arranged on the rotating main body lower cover plate 22;
[0033] Among them, a rotating track 131 is provided on the inner wall of the rotating large gear 13, and a convex block 232a that cooperates with the rotating track 131 is provided on the outer wall of the rotating rising fixed upper bracket 232. When the stepper motor 11 drives the rotating large gear 13 to rotate through the pinion 12, the rotating large gear 13 moves up and down and drives the decorative component 3 to move up and down at the same time, as Figure 4 shown. A slot 5 is formed between the rotating large gear 13 and the rotating main body bracket 21, and damping grease is filled in the slot 5. In a preferred embodiment, the slot 5 will be filled with damping grease.
[0034] Specifically, the stepper motor 11 has a forward rotation movement or a reverse rotation movement. Forward rotation can drive the decorative component 3 to move upward, and reverse rotation can drive the decorative component 3 to move downward.
[0035] Specifically, the rotating large gear 13 includes a gear portion 132 provided in the lower section and a connecting portion 133 provided in the upper section. Among them, the gear portion 132 meshes with the pinion 12, and the connecting portion 133 is connected to the decorative component 3.
[0036] Specifically, an activity chamber is provided inside the rotating main body bracket 21, and the rotating large gear 13 can move up and down inside the activity chamber.
[0037] Specifically, an installation seat 211 for the stepper motor 11 is provided on the side of the rotating main body bracket 21, and the stepper motor 11 is installed on the installation seat 211.
[0038] Specifically, the decorative component 3 includes a metal mesh 31, an electroplated decorative surface 32, and a metal mesh / electroplated decorative surface fixed bracket 33. Both the metal mesh 31 and the electroplated decorative surface 32 are installed on the metal mesh / electroplated decorative surface fixed bracket 33.
[0039] Specifically, the decorative component 3 is detachably arranged so that different-shaped decorative components 3 can be replaced as needed.
[0040] Preferably, as Figure 2 shown, when the large rotating gear 13 moves up and down, it drives the decoration component 3 to move up and down. The state is that after rotating and rising from the initial position to the predetermined position, it stops rising and can keep rotating slowly at the existing speed. The height difference between the initial position and the predetermined position is 8 mm (millimeters).
[0041] Of course, according to actual needs, the height difference of the predetermined position can be greater than or less than 8 mm (millimeters), and it can be achieved only by adjusting the relevant structural height as required.
[0042] Specifically, the rotating and rising fixing bracket 23 includes a rotating and rising fixing lower bracket 231 and a rotating and rising fixing upper bracket 232, and the rotating and rising fixing lower bracket 231 is connected to the rotating and rising fixing upper bracket 232.
[0043] Specifically, the rotating and rising fixing lower bracket 231 is provided with a limiting block 231a, and the width of the limiting block 231a is basically equal to the width of the slot 5.
[0044] During operation, when the stepping motor 11 drives the large rotating gear 13 to rotate through the small gear 12, the large rotating gear 13 moves up and down while driving the decoration component 3 to move up and down. A slot 5 is formed between the large rotating gear 13 and the rotating main body bracket 21. Damping grease is poured into the slot 5, and then the rotating main body lower cover plate 22 is combined and fixed to complete the sealing of the damping grease, so that it forms a sealed body, thereby enabling a structural action of first rotating and rising, and then keeping rotating slowly at the existing speed after rotating and rising to the predetermined position.
[0045] Specifically, during the process of rotating and rising or falling, a part is the fixed component, and the other part is the movable component that rises or falls. Among them, the large rotating gear 13 and the decoration component 3 are movable components and can move up and down; while the rotating component 2 and the tweeter 4 are fixed components and cannot move up and down.
[0046] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
