Embodiment 1

[0051]

[0052]

[0055] In the HUD system, the first drive motor 203 and the second drive motor 302 can be driven during operation

[0056] When the second drive motor 302 is locked, the first drive motor 203 rotates, thereby driving the second link 202 and the first

[0057] The first drive motor 203 and the second drive motor 302 move in combination with each other, so that the height adjustment of the HUD,

[0066] The adjustment amount is output to the first drive motor 203 and the second drive motor 302.

Abstract

The present invention relates to the technical field of head-up display devices, in particular to a head-up display device with adjustable viewing distance of a virtual image and a control method thereof. It includes the main body of the head-up display device and an external support, and also includes a driving link assembly and a driven link assembly. The driving link assembly and the driven link assembly are symmetrically distributed on both sides of the head-up display body, and It is rotatably connected with the upper part of the head-up display device body. The drive link assembly on the active side includes a first drive link assembly and a second drive link assembly. The first drive link assembly includes a first link and a second link. The first link One end of the rod is connected to one end of the second connecting rod and the angle at the connection is adjustable, the other end of the first connecting rod is connected to the upper part of the head-up display device in rotation, the other end of the second connecting rod is connected to the external support in rotation, and the second driving The upper end of the connecting rod assembly is transmission-connected to the upper end of the head-up display device body, and the lower end is rotationally connected to the external support member.

Description

Head-up display device with adjustable virtual image viewing distance and control method thereof technical field The present invention relates to the technical field of head-up display device, be specifically related to a kind of head-up display device with adjustable virtual image viewing distance settings and how to control them. Background technique Due to the difference in the body shape of different drivers, the visual range of the driver is quite different, and the imaging range that can be satisfied by the HUD [1]. The range is limited, so the imaging range needs to be adjusted to meet different driver's field of vision requirements. The adjustable spherical mirror is used inside the HUD Now the adjustment of the projection light path of the head-up display, by rotating the adjustable spherical mirror, adjusts the imaging angle range of the virtual image, so as to realize The height of the virtual image can be adjusted to meet the requirements of different dr...
