[0006] Chinese Patent 202321683158.4 discloses a soundbar and an automobile. The soundbar includes a fixed shell, a grille, a speaker assembly, and a flip adjustment mechanism. A receiving cavity is formed inside the fixed shell, the grille is assembled inside the receiving cavity, the speaker assembly is disposed inside the grille, and the grille has sound transmission holes corresponding to the speaker assembly. The flip adjustment mechanism is fixed to the fixed shell and connected to the grille for driving the grille to rotate.

[0007] The disadvantages of the above technical solution are that the rotating component has a solid pivot (hinge), and when the rotating lifting mechanism rotates, the rear end of the rotating component will change with the gap of the moving surface, resulting in poor consistency of the rear end gap before and after lifting. In addition, internal parts are easily damaged when pressed by external force.

[0008] Therefore, providing a shaftless flipping device with good consistency in the rear end clearance before and after lifting is a problem that needs to be solved. Summary of the Invention

[0009] To address the shortcomings of existing technologies, the main objective of this invention is to provide a shaftless flipping device with good consistency in the rear end gap before and after lifting, and automatic unloading when pressed by external force to protect internal parts.

[0010] To achieve the above-mentioned main objectives, this utility model provides a shaftless flipping device, which includes:

[0011] A drive motor, which includes a drive shaft;

[0012] The transmission mechanism includes an input gear and an output gear; the input gear and the drive shaft form a worm gear mechanism.

[0013] The flipping component has an arc-shaped part with gear teeth on its outer arc surface to form a toothed arc surface; the toothed arc surface meshes with the output gear; the left and / or right sides of the flipping component have arc-shaped guide plates.

[0014] The inner housing serves as the housing for the flipping component; the drive motor and transmission mechanism are both mounted on the inner housing; the main body of the flipping component is located inside the inner housing, and the top of the inner housing is open; the side of the inner housing is provided with an arc-shaped guide groove, and the arc-shaped guide plate is located inside the arc-shaped guide groove.

[0015] The shaftless flipping device of this invention can be applied to rotating decorative or functional parts in the automotive interior and home appliance industries. For example, the flipping component can be used for speakers in vehicles.

[0016] In this invention, the toothed arc surface is concentric with the flipping center.

[0017] In this invention, a drive motor drives a toothed arc surface through a transmission mechanism, thereby causing the arc-shaped guide plate of the flipping component to move along the arc-shaped guide groove, thus achieving flipping or rotation. Position switches are set at the start and end positions. When the arc-shaped component reaches the set position, the position switch is activated, sending a position signal to the drive motor, causing the drive motor to stop at the set position.

[0018] According to a specific embodiment of this utility model, the transmission mechanism includes a first gear shaft and a second gear shaft; both the first gear shaft and the second gear shaft are mounted on a mounting plate; an input gear and a first transmission wheel are sleeved on the first gear shaft; a second transmission wheel and an output gear are sleeved on the second gear shaft; the first transmission wheel and the second transmission wheel mesh. The overall transmission path of the device is: drive motor – drive shaft – input gear – first gear shaft – first transmission wheel – second transmission wheel – output gear – arc-shaped component.

[0019] According to a specific embodiment of this utility model, the first gear shaft is a splined shaft. The input gear, the first gear shaft, and the first transmission wheel are driven by a spline.

[0020] According to one specific embodiment of this utility model, the second gear shaft is an optical shaft. The second transmission wheel and the output gear are driven by friction.

[0021] According to a specific embodiment of this utility model, an adjusting nut is provided on the outer side of the output gear on the second gear shaft. This adjusting nut is used to adjust the friction between the second transmission wheel and the output gear. When the flipping component is subjected to a large impact force sufficient to overcome the friction force, the output gear rotates, while the second transmission wheel is not driven to rotate. This protects the transmission mechanism and drive motor from damage caused by external impacts or pressure.

[0022] According to a specific embodiment of the present invention, the arc-shaped component is located at the bottom of the flipping component, and the drive motor, transmission mechanism, and arc-shaped component are located inside the inner shell.

[0023] According to a specific embodiment of the present invention, the arc-shaped component is mounted on the arc-shaped guide plate, and the drive motor, transmission mechanism, and arc-shaped component are located outside the inner shell; an mounting plate is provided on the outer side of the inner shell, and the drive motor and transmission mechanism are both mounted on the mounting plate.

[0024] According to a specific embodiment of the present invention, the left and right sides of the flipping component are provided with arc-shaped guide plates, arc-shaped parts, and arc-shaped guide grooves; one side is the driven side and the other side is the undriven side.

[0025] According to a specific embodiment of the present invention, a support wheel is provided on the non-drive side. The support wheel is the same as the output gear, is located on the opposite side of the output gear, and meshes with the toothed arc surface of the non-drive side.

[0026] According to one specific embodiment of this utility model, the flipping component is a vehicle speaker.

[0027] This utility model has the following beneficial effects:

Flipping has no impact on the rear end clearance, and the rear end clearance remains consistent before and after flipping. The second gear shaft is a smooth shaft, and the second transmission wheel and output gear are driven by friction. This protects the transmission mechanism and drive motor from damage caused by external impacts or pressure.
