The curved mirror 37 is fixed on the housing 31 for reflecting imaging light. The cover 39 is fixed on the housing 31 and used to close the housing 31 .

Among them, the light source unit 33 may be called an image source. The screen 35 can reflect the imaging light emitted by the light source unit 33 to the curved mirror 37 and transmit the imaging light reflected by the curved mirror 37 .

In conventional optical displays, optical components such as light sources and curved mirrors are first fixed to their respective fixed frames and then assembled into the housing. As a result, the optical display has a large number of components. There are assembly tolerances in the assembly between components. The greater the number of components, the more difficult it is to assemble the system or equipment and the lower the assembly accuracy may be.

In this application, since the light source unit 33, the screen 35 and the curved mirror 37 are directly fixed on the same housing 31 without using other adapters (such as respective fixed frames), the number of components of the optical display 103 is reduced. The assembly difficulty of the optical display 103 is reduced, the assembly accuracy of the optical display 103 is improved, and the structure of the optical display 103 is simplified, which is beneficial to improving the accuracy of the optical path system of the optical display 103 and improving the output quality of the imaging light of the optical display 103 .

Please refer to FIG. 5 b and FIG. 5 c in conjunction. The housing 31 includes a first mounting part 312 and a second mounting part 314 arranged along a first direction (the X direction shown in FIG. 5 a, 5 b and 5 c). The first mounting part 312 is used to mount the light source unit 33 . The first mounting part 312 is provided with an assembly port 3122 (as shown in FIG. 5c ) that is connected to the inner cavity of the first mounting part 312 to facilitate placing the light source unit 33 into the first mounting part 312 through the assembly port 3122 . lumen.

The length of the first mounting part 312 along the second direction (the Y direction shown in FIG. 5b and FIG. 5c ) is smaller than the length of the second mounting part 314 along the second direction. The second direction is different from the first direction. The outer wall of the first mounting part 312 and the outer wall of the second mounting part 314 together form a first accommodating space 317 and a second accommodating space 318 . Along the second direction, the first mounting portion 312 is located between the first accommodating space 317 and the second accommodating space 318 . The first accommodation space 317 is used to accommodate the control component 40 . Viewed along the third direction (Z direction as shown in Figure 5b), the shape of the housing 31 is generally T-shaped. The third direction is different from the first direction, and the third direction is different from the second direction. In some embodiments of the present application, the first direction is perpendicular to the second direction, the second direction is perpendicular to the third direction, and the third direction is perpendicular to the first direction.

The inner cavity of the second mounting part 314 is connected with the inner cavity of the first mounting part 312 . The second mounting part 314 is provided with a mounting opening 3142 connected with the inner cavity of the second mounting part 314 for mounting the screen 35 .

The light source unit 33 is fixed in the inner cavity of the first mounting part 312 . The light source unit 33 adopts liquid crystal display (LCD) imaging technology. LCD imaging utilizes the principle of the photoelectric effect of liquid crystal. Liquid crystal molecules change their arrangement state under the influence of an external electric field. Liquid crystal molecules in different arrangements can control the light transmittance. For example, there are liquid crystal molecules in the middle of two polarizers whose polarization directions are perpendicular to each other. When no electric field is applied, the liquid crystal molecules can rotate the polarization direction of the linearly polarized light passing through the first polarizer by 90°. At this time, the light transmits at its maximum rate through the second polarizer; when an electric field is applied, the arrangement state of the liquid crystal molecules changes, the rotation angle of the polarized light also changes, and the intensity of the light passing through the second polarizer weakens. Each pixel of the LCD display is composed of three primary colors, and the display of color images is achieved by controlling the intensity of the three primary colors. This application does not limit the type of light source of the light source unit 33. For example, the light source unit 33 may also adopt digital light processing (DLP) technology, laser scanning projection, etc.

The screen 35 is fixedly connected to the housing 31 . The screen 35 covers the installation opening 3142, thereby closing the second installation part 314. The screen 35 can be connected and fixed with the housing 31 through glue dispensing or double-sided tape. In some embodiments of the present application, the normal direction of the screen 35 is parallel to the third direction. The screen 35 is an optical element capable of transmitting part of the incident light incident on the screen 35 and/or reflecting part of the incident light, that is, the screen 35 is a transflective optical element. For example, screen 35 may transmit 50% of incident light, and screen 35 may reflect 50% of incident light; or, screen 35 may transmit 30% of incident light, and screen 35 may reflect 70% of incident light. The proportion of incident light transmitted by the screen 35 to the total incident light can be selected according to needs. The material of the screen 35 can be transflective glass or the like.

In this embodiment, the curved mirror 37 is a free-curved mirror that matches the requirements of optical imaging.

The surface shape of optical elements used in traditional optical design is a standard spherical surface, which generally requires multiple spherical mirrors to correct aberrations, resulting in a relatively complex optical structure and a large space occupied.

With the development of the optical industry, the design and manufacturing technology of aspherical surfaces with relatively complex surface shapes has been greatly improved. Aspherical surfaces generally refer to quadratic surfaces such as paraboloids, ellipsoids, involutes, and hyperboloids with an axis of rotation. As well as higher-order surfaces, there are also non-rotational aspherical surfaces, such as off-axis aspherical surfaces. Depending on the usage scenario, one aspherical surface can usually replace two or more spherical surfaces to correct aberrations, thereby simplifying the optical structure and achieving miniaturization and lightweighting of the optical path.

Compared with aspheric surfaces, free-form surfaces are optical structures with a more complex surface shape. The curvature radii of each point on the surface are different, and the surface shape has a very high degree of freedom. The free-form surface can not only replace multiple aspherical surfaces to correct aberrations, but also maximize the optical quality and streamline the optical structure. The optical free-form surface has a complex structure, high degree of freedom, and no clear expression definition. It is generally considered that an optical surface that does not have global rotational symmetry, has no unified optical axis, and has multiple curvature radii on the entire surface is an optical free-form surface.

In other embodiments of the present application, the curved mirror 37 may also be a spherical reflector or an aspherical reflector, which is not limited in the present application.

The control component 40 is at least partially received in the first accommodation space 317 and located outside the housing 31 . The control component 40 is electrically connected to the light source unit 33 .

Since the control component 40 is disposed in the first accommodation space 317 of the housing 31, that is, the control component 40 and the light source unit 33 located in the inner cavity of the housing 31 are not disposed in the same cavity, the control component 40 does not occupy the internal space of the housing 31.

For example, the display body 30 can be rotated to the first state, that is, when the display body 30 is completely received in the receiving cavity 1015 (the screen 35 is located inside the receiving cavity 1015). The sliding cover 64 can be driven by the sliding cover movement mechanism 62 to rotate relative to the first support frame 10 along a first direction (for example, clockwise). When the second rod part 6424 resists the support part 12 (as shown in Figure 3, Figure 13a and Figure 13b), due to the limiting effect of the second rod part 6424, the sliding cover 64 cannot continue to rotate along the first direction, and the sliding cover 64 Moving to the second position, the sliding cover 644 blocks the screen 35 and covers the opening 1017.

The sliding cover 64 can be driven by the sliding cover movement mechanism 62 to rotate in a second direction (for example, counterclockwise) relative to the first support frame 10 . When the first rod part 6422 resists the support part 12 (as shown in Figure 2, Figure 11a and Figure 11b), due to the limiting effect of the first rod part 6422, the sliding cover 64 cannot continue to rotate along the second direction, and the sliding cover 64 Moving to the first position, the sliding cover 644 does not block the screen 35 and does not block the opening 1017 . The display body 30 can be driven by the main movement mechanism 50 to adjust its posture. For example, the display body 30 extends out of the bearing component 101 through the opening 1017 , or retracts into the receiving cavity 1015 of the bearing component 101 through the opening 1017 .

It can be understood that the first sensor 91 can be provided on the first rod portion 6422 and/or the first support frame 10 . When the first rod portion 6422 contacts the first support frame 10, the first sensor 91 generates a first signal and feeds it back to the control component. The control component determines that the sliding cover 64 reaches the first position according to the first signal. The second sensor 93 is communicatively connected with the control component, and the second sensor 93 is used to sense whether the sliding cover 64 reaches the second position. The second sensor 93 is provided on the first support frame 10 . It can be understood that the second sensor 93 can be provided on the second rod portion 6424 and/or the first support frame 10 . When the second rod portion 6424 comes into contact with the first support frame 10, the second sensor 93 generates a second signal and feeds it back to the control component. The control component determines that the sliding cover 64 reaches the second position according to the second signal. The first sensor 91 may be a micro switch or an infrared detector or other sensing device, and the second sensor 93 may be a micro switch or an infrared detector or other sensing device. The first sensor 91 automatically detects that the sliding cover 64 reaches the first position, and the second sensor 93 automatically detects that the sliding cover 64 reaches the second position, thereby improving the automation and intelligence of the optical display assembly.
