The elastic pressing component 4 is positioned on one side of the image generation unit 3 far away from the adjusting component 2, and the elastic pressing component 4 can elastically press the image generation unit 3 on the mounting shell 1 along the first direction.
When the image generation unit installation position adjusting mechanism provided by the embodiment is used, the elastic pressing component 4 is firstly adopted to pre-press the image generation unit 3 on the installation shell 1, the adjusting piece 21 on the installation shell 1 is screwed, so that the adjusting piece 21 moves back and forth along the first direction, so that the adjusting piece 21 approaches or moves away from the image generating unit 3 and adjusts the position of the image generating unit 3 in the first direction, since the elastic pressing member 4 elastically presses the image generating unit 3 against the mounting case 1, the image generating unit 3 is always clamped between the elastic pressing member 4 and the adjusting member 21, and after the position of the image generating unit 3 is adjusted, the adjusting member 21 is kept still, and the image generating unit 3 is locked on the mounting case 1 by the locking member 22, at this time, the mounting position of the image generating unit 3 is adjusted in place, and the elastic pressing member 4 is removed.
That is, in the present embodiment, since the adjuster 21 is movable in the first direction to abut against the image generating unit 3, the elastic pressing member 4 can elastically press the image generating unit 3 against the mounting case 1 in the first direction, and the arrangement is such that the image generating unit 3 has an adjustment gap between the adjuster 21 and the elastic pressing member 4 at the initial stage of mounting, thereby making it possible to adjust the mounting position of the image generating unit 3. After the mounting position of the image generating unit 3 is adjusted in place, the image generating unit 3 may be locked to the mounting case 1 by using the locking member 22.
Specifically, in the present embodiment, the mounting case 1, the adjustment assembly 2, and the image generation unit 3 all belong to a part of the HUD. The flat mirror 10, the large mirror, the small mirror, and other optical elements of the HUD are mounted on the mounting case 1.
Specifically, the elastic pressing assembly 4 includes a power source 41 and an elastic pressing head 42.

Specifically, an external force application tool may be employed to apply a force in the radial direction of the connecting shaft 221 to the image generating unit 3 and keep the force at all times, thereby ensuring the positional stability of the image generating unit 3. Alternatively, the external force application tool may be an externally applied pneumatic, hydraulic or mechanical tool. For example, the external force application tool may be an air cylinder, and an output rod of the air cylinder can extend and contract along the radial direction of the connecting shaft 221, so as to apply an acting force along the radial direction of the connecting shaft 221 to the image generation unit 3 and keep the acting force until the abutting cap 222 abuts against the side of the mounting case 1 away from the image generation unit 3. Or, a manual force along the radial direction of the connecting shaft 221 may be applied to the image generating unit 3, and after the position of the image generating unit 3 is adjusted to the proper position, the abutting cap 222 abuts against the side of the mounting case 1 away from the image generating unit 3.
