Further, in one embodiment, the rotating gear set is connected to the refractive structure of the optical path structure, and the rotating gear set drives the refractive structure to adjust the optical path of the polarized light so as to make the polarized light incident into the polarization structure. The design is suitable for a specific structure that the liquid crystal display structure is not moved and the direction of the polarized light emitted by the liquid crystal display structure is not changed, and the light path of the polarized light can be adjusted only through the refraction change of the light path structure so as to enable the polarized light to be incident into the polarized structure; the liquid crystal display structure is fixed, so that the installation stability and the use stability of the liquid crystal display structure are ensured; on the other hand, the driving connection of the light path structure has long service life, and basically can run through the whole life cycle of the liquid crystal display structure in normal test, so that the whole manufacturing and use are facilitated; on the other hand, when the mobile terminal is used, the light path of the polarized light is adjusted through the light path structure, the head-up display effect is achieved, a user does not need to look up the display content of the mobile terminal in a head-down mode, and potential safety hazards which may be generated during driving are avoided.

In each embodiment, the factory setting of the preset range can be flexibly set according to the use requirement and the use environment, and can also be adjusted by the user. Further, in one embodiment, the preset range includes a specific angle, for example, a cone angle of less than 80 degrees is formed by taking a center of a display surface of the liquid crystal display structure as a center, and taking a straight line which is perpendicular to the display surface and passes through the center as an axis; the included angle between two generatrices of the axial section of the cone taking the center of the display surface of the liquid crystal display structure as a vertex is less than 80 degrees; the specific angle is a cone angle of less than 80 degrees. Alternatively, the specific angle is a taper angle of less than 60 degrees; alternatively, the specific angle is a taper angle of less than 50 degrees. In one embodiment, the preset range comprises a specific length, the specific length is a straight line which is perpendicular to and passes through the center of the display surface of the liquid crystal display structure, and one point of the straight line is away from the center; in one embodiment, the specific length is less than 150 centimeters; in one embodiment, the specific length is less than 120 centimeters; in one embodiment, the specific length is less than 100 centimeters.

Further, in one embodiment, the reset structure is respectively connected to the detection unit and the driving unit, and respectively transmitted to the reset structure and the driving unit or the controller thereof, the reset structure preferentially determines whether the position of the polarization structure exceeds a preset range, and sends a reset signal to the detection structure or the detection unit thereof in a state that the position of the polarization structure exceeds the preset range, and the detection structure or the driving unit thereof controls the light path structure to reset; and under the condition that the position of the polarization structure does not exceed a preset range, the position of the light path structure is controlled by the detection structure or the driving unit thereof or the controller thereof. The design is beneficial to avoiding that the position of the polarization structure exceeds a preset range when a user carries the polarization structure away, the user usually carries a helmet or glasses and is in a motion state in the use process, sometimes the user possibly leaves the detection range of the detection structure, if the light path structure is driven all the time, the normal service life of the light path structure is possibly influenced and damaged, and therefore the position of the light path structure is required to be stopped being adjusted when the user exceeds the preset range; and controlling the resetting of the optical path structure is also beneficial to adopting an automatic program, so that the optical path structure is known where to start to be controlled and the effective position control is realized.
In order to protect the optical path structure and the liquid crystal display structure, in one embodiment, the augmented reality head-up display device further includes a transparent plate disposed between the optical path structure and the polarization structure; in practical application, the transparent plate can be realized by adopting a plastic plate such as an organic glass plate and the like and is used for protecting a light path structure, a liquid crystal display structure and other structures; for example, the transparent plate is covered on the instrument panel.
