Description

Technical Field

[0001] This utility model belongs to the field of HUD technology, specifically relating to an adaptive zoom ARHUD structure. Background Technology

[0002] Most existing AR-HUDs only display information such as vehicle speed and navigation using a single image plane with a fixed focal length or a dual image plane with a fixed focal length. Because there is only a single focal plane at a fixed distance, prolonged use can cause eye fatigue and dizziness. At the same time, the image displayed by a single focal plane lacks realistic visuals. Dual image planes often place information according to categories and comfort levels on different screens. Although this does not make the screen cluttered, it is difficult for the driver to find information. Since the current single and dual focal planes are both fixed focal lengths, they cannot automatically adjust the virtual image according to different road conditions. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an adaptive zoom ARHUD structure, which aims to solve the problem that existing technologies, where both single and dual focal planes have fixed focal lengths, cannot automatically adjust the virtual image according to different road conditions.

[0005] (2) Technical solution

[0006] To address the aforementioned technical problems, this utility model provides an adaptive zoom ARHUD structure, comprising a housing; a lens slidably mounted on the housing; a zoom assembly for driving the lens to a designated position for operation; and an LCD module fixedly mounted on the housing.

[0008] Furthermore, the lens is fixedly mounted on the mounting housing, and a connecting block is fixedly mounted on one side of the mounting housing, the connecting block being fixedly connected to the rack.

[0009] Furthermore, one side of the mounting housing is slidably mounted on the guide rail.

[0013] Beneficial effects

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the lens is moved to the working position by the zoom component to transform the bifocal virtual image into a trifocal virtual image (the principle of transforming a monofocal image into a bifocal image is the same). This allows the invention to adjust the lens position by moving the lens through the zoom component according to different road conditions and after receiving information from the vehicle's infotainment system. In other words, the invention can automatically adjust the virtual image to monofocal / bifocal / trifocal according to different road conditions. Attached Figure Description

[0020] This specific implementation is an adaptive zoom ARHUD structure, and its structural diagram is shown below. Figures 1-3 As shown, it includes a housing 1, a lens 2, a zoom assembly 3, and an LCD module 4. The lens 2 is slidably mounted on the housing 1. The zoom assembly 3 is used to drive the lens 2 to a designated position for operation. The LCD module 4 is fixedly mounted on the housing 1.

[0021] In this invention, the zoom component 3 drives the lens 2 to move to the working position to transform the bifocal virtual image into a trifocal virtual image (the principle of monofocal to bifocal conversion is the same). This allows the invention to adjust the position of the lens 2 by moving it through the zoom component 3 according to different road conditions and after receiving information from the vehicle's infotainment system. Therefore, this invention can automatically adjust the virtual image to monofocal / bifocal / trifocal according to different road conditions.

[0022] In this embodiment, the zoom assembly 3 includes a drive motor 301 fixedly installed inside the housing 1, a worm gear 302 fixedly installed at the output end of the drive motor 301, and a rack 303 meshing with the worm gear 302.

[0023] The lens 2 is fixedly mounted on the mounting housing 5. A connecting block 6 is fixedly mounted on one side of the mounting housing 5, and the connecting block 6 is fixedly connected to the rack 303.

[0024] The specific process of zoom assembly 3 driving lens 2 to move is as follows:

[0025] The worm gear 302 is driven to rotate forward by the drive motor 301. During the rotation, the worm gear 302 can drive the rack 303 to move closer to the drive motor 301. During the movement, the rack 303 can drive the connecting block 6 to move synchronously closer to the drive motor 301. During the movement, the connecting block 6 can drive the mounting shell 5 and the lens 2 to move synchronously closer to the drive motor 301.

[0026] Similarly, the worm gear 302 is reversed by the drive motor 301, and the lens 2 moves away from the drive motor 301.

[0027] The drive motor 301 drives the rack 303 through the worm gear 302, causing the lens 2 to move in a straight line, thereby allowing the lens 2 to reach the designated position to work. The movement of the lens 2 can realize the transformation of the bifocal virtual image into a trifocal virtual image (the principle of transforming a monofocal image into a bifocal image is the same).

[0028] In this embodiment, one side of the mounting shell 5 is slidably mounted on the guide rail 7. Specifically, one side of the mounting shell 5 has a through hole. The cross-section of the through hole is greater than or equal to the cross-section of the guide rail 7 to enable the movement of the mounting shell 5. When the cross-section of the through hole is greater than the cross-section of the guide rail 7, the movement of the mounting shell 5 can be satisfied. When the cross-section of the through hole matches the cross-section of the guide rail 7, the mounting shell 5 can move linearly along the guide rail 7 under the action of the through hole and the guide rail 7, and the movement of the mounting shell 5 is smooth and will not deviate.

[0029] In this embodiment, the connecting block 6 is slidably mounted on the guide rail 7. Specifically, the connecting block 6 has a guide rail hole that cooperates with the guide rail 7. Under the action of the guide rail hole, the connecting block 6 can stably move in a straight line along the guide rail 7.

[0030] The guide rail 7 is fixedly installed on the housing 1, and the housing 1 provides support and fixation for the guide rail 7.

[0031] In this embodiment, a guide sleeve 8 is fixedly installed on the other side of the mounting shell 5, and a guide rail 2 9 that cooperates with the guide sleeve 8 is fixedly installed on the outer shell 1. The guide sleeve 8 is slidably installed on the guide rail 2 9. The inner diameter of the guide sleeve 8 is equal to the outer diameter of the guide rail 2 9. With the cooperation of the guide sleeve 8 and the guide rail 2 9, the mounting shell 5 moves linearly along the guide rail 2 9, which can guide the movement of the mounting shell 5, so that the movement of the mounting shell 5 is smooth and there is no deviation.

[0032] When the drive motor 301 drives the worm gear 302 to rotate forward, the worm gear 302 can drive the rack 303 to move along the guide rail 7 and the guide rail 9 towards the drive motor 301 during the rotation. During the movement, the rack 303 can drive the connecting block 6 to move synchronously along the guide rail 7 and the guide rail 9 towards the drive motor 301. During the movement, the connecting block 6 can drive the mounting shell 5 and the lens 2 to move synchronously along the guide rail 7 and the guide rail 9 towards the drive motor 301.

[0033] It also includes a decorative cover 10, which is fixedly installed on the housing 1. Under the action of the decorative cover 10, the zoom component 3 can be covered and protected.

[0034] In summary, in this invention, the zoom component 3 drives the lens 2 to move to the working position to transform the bifocal virtual image into a trifocal virtual image (the principle of transforming a monofocal image into a bifocal image is the same). This allows the invention to adjust the position of the lens 2 by moving it through the zoom component 3 according to different road conditions and after receiving information from the vehicle's infotainment system. In other words, the invention can automatically adjust the virtual image to monofocal / bifocal / trifocal according to different road conditions.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
