[0020] In order to make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] As Figures 1 to 4 shown, an electric rotating mechanism for vehicle-mounted holographic projection of the present utility model includes a holographic projection assembly 1, a main board 2, a rotating bracket 3, a motor 4, a worm 5, a helical gear assembly 6, and a base 7. The holographic projection assembly 1, the main board 2, the motor 4, and the worm 5 are all connected to the rotating bracket 3 to form a rotating part, and the helical gear assembly 6 is fixedly connected to the base 7 to form a fixed part. The worm 5 is docked with the helical gear assembly 6, and the motor 4 drives the worm 5 to make the rotating part rotate relative to the fixed part.

[0022] The entire mechanism is divided into a rotating part and a fixed part. The rotating part includes: a holographic projection assembly 1, a main board 2, a motor 4, and a worm 5, which are respectively installed on the upper and lower sides of the rotating bracket 3 and become rotating devices that rotate around the central axis. The fixed part includes: a helical gear assembly 6 and a base 7, which are fixed by screws. Different from common designs, in this design, the helical gear assembly 6 is fixed and immovable. After being powered on, since the helical gear assembly 6 is a fixed and immovable component, the motor 4 and the worm 5 drive the rotating part to rotate self, and at the same time revolve around the central axis of the helical gear assembly 6.

[0023] The main board 2, the holographic projection assembly 1, and the motor 4 are installed on the same rotating bracket 3 and rotate synchronously, which can ensure that the two ends of the connectors of the holographic projection assembly 1, the motor 4, and the main board 2 are stationary, avoiding the pulling and jamming of wires.

[0024] A motor bracket 31 is fixedly connected to the bottom of the rotating bracket 3. The worm 5 is movably connected inside the motor bracket 31. The motor 4 is fixed on the motor bracket 31, and the output end of the motor 4 is connected to one end of the worm 5. Through the motor bracket 31, the motor 4 and the worm 5 can be fixed on the rotating bracket 3 and move synchronously with the rotating bracket 3. At the same time, the rotation driven by the motor 4 is transmitted to the rotating bracket 3, driving the main board 2 and the holographic projection assembly 1 to rotate together.

[0025] The helical gear assembly 6 includes a helical gear bracket 61 and an arc-shaped helical gear bar 62. The rotating bracket 3 is slidably connected to the helical gear bracket 61. The helical gear bar 62 is connected to the side of the helical gear bracket 61. The helical gear bar 62 meshes with the worm 5, and the rotating bracket 3 revolves around the central axis of the helical gear bracket 61. The arc-shaped structure design of the helical gear bar 62 can ensure that the worm 5 is always meshed with the helical gear bar 62 when the rotating bracket 3 rotates relative to the helical gear bracket 61, ensuring continuous power transmission. At the same time, it can make the rotating bracket 3 revolve around the central axis of the helical gear bar 62 to drive the rotating part of the entire mechanism to rotate. The rotating part can rotate forward and backward by 35°.

[0026] A circular chute 63 is provided at the top of the helical gear support 61, and a protruding slider 32 is provided at the bottom of the rotating support 3. The slider 32 is slidably connected within the chute 63. The slider 32 can preferably be arranged on the inner wall of the inner ring between rotations. Through the cooperative connection of the slider 32 and the chute 63, the rotating support 3 can rotate smoothly relative to the helical gear support 61 and is not easily detached.

[0027] An avoidance position 64 is provided at the upper edge of the chute 63, and the slider 32 is inserted into the chute 63 through the avoidance position 64. The width of the avoidance hole can be slightly larger than the width of the slider 32, which facilitates the docking, disassembly, and assembly of the slider 32 and the avoidance hole.

[0028] The helical gear support 61 is provided with a mounting position 65, and the mounting position 65 of the helical gear support 61 is fixed to the base 7 by screws. The method of fixing by screws can facilitate the assembly of the helical gear support 61 and the base 7, and after assembly, the helical gear support 61 and the base 7 can form a fixed whole, serving as the fixed part of the entire mechanism, enabling the rotating part of the mechanism to rotate relative to this fixed part.

[0029] The holographic projection component 1 is fixedly connected to the top of the rotating support 3. The holographic projection component 1 is composed of a lens and a mirror inside, and is used to project the picture holographically to the outside for users to view. The holographic projection component 1 is fixed to the top of the rotating support 3, which can make the holographic projection component 1 higher than the base 7, avoiding other components from blocking the projection light, and the holographic projection component 1 can rotate synchronously with the rotating support 3.

[0030] The main board 2 is connected inside the holographic projection component 1. The rotating support 3 is provided with a wire harness hole 33, and the wire harness 21 at the bottom of the main board 2 passes through the wire harness hole 33 and enters the base 7. The main board 2 is used to control the holographic projection component 1 and the motor 4. A voice control component, etc. can be added to the main board 2, and the projection of the holographic projection component 1 and the rotation of the motor 4 can be controlled by voice control. The main board 2 being connected inside the holographic projection component 1 can avoid the exposure of the main board 2 and also facilitate the connection of the internal wiring. The wire harness 21 of the main board 2 passes through the wire harness hole 33 and enters the base 7 and is used for external power supply.

[0031] Compared with the prior art, the present utility model realizes the rotation action of the holographic projection product. The wiring of the holographic projection component 1 and the wire harness of the motor 4 can both remain stationary relative to both ends of the connector; effectively avoiding the risks of the wire being pulled and stuck during the rotation of the rotating device, resulting in durability failure and action jamming. At the same time, the overall volume can be extremely reduced, improving the competitiveness of the product.

[0032] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present utility model.
