The light source unit 33 is fixed to the inner cavity of the first mounting portion 312. The light source unit 33 employs a liquid crystal display (liquid crystal display, LCD) imaging technique. The LCD imaging utilizes the photoelectric effect principle of liquid crystal, liquid crystal molecules are influenced by an external electric field to change the arrangement state, and the liquid crystal molecules in different arrangement states can control the transmittance of light. For example, a liquid crystal molecule is arranged between two polarizers with mutually perpendicular polarization directions, and when no electric field is applied, the liquid crystal molecule can rotate the polarization direction of linearly polarized light passing through the first polarizer by 90 degrees, and at the moment, the light passes through the second polarizer with the maximum transmittance; when an electric field is applied, the arrangement state of the liquid crystal molecules is changed, the rotation angle of polarized light is also changed, and the intensity of light transmitted through the second polaroid is weakened. Each pixel point of the LCD display screen is composed of three primary colors, and the display of a color image is realized by controlling the intensity of the three primary colors. The kind of light source of the light source unit 33 is not limited in the present application, and for example, the light source unit 33 may also employ digital light processing (digital light processing, DLP) technology, laser scanning projection, or the like.
The screen 35 is fixedly connected with the housing 31. The screen 35 covers the mounting opening 3142, thereby closing the second mounting portion 314. The screen 35 may be attached to the housing 31 by dispensing or double sided adhesive. 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, i.e. the screen 35 is a transflective optical element. For example, the screen 35 may transmit 50% of the incident light, and the screen 35 may reflect 50% of the incident light; alternatively, the screen 35 may transmit 30% of the incident light, and the screen 35 may reflect 70% of the incident light. The proportion of the incident light transmitted by the screen 35 to the whole incident light can be selected according to the requirement. The screen 35 may be made of transparent glass or the like.
In the present embodiment, the curved mirror 37 is a mirror that matches the free-form surface required for optical imaging.
The surface type of the optical element adopted in the traditional optical design is a standard spherical surface, and a plurality of spherical mirrors are generally required to be matched for correcting the aberration, so that the optical structure is complex, and the occupied space is large.
With the development of optical industry, design and manufacturing technology of an aspheric surface with a relatively complex surface shape are greatly improved, and the aspheric surface generally refers to a quadric surface such as a paraboloid, an ellipsoid, an involute surface, a hyperboloid and the like with a rotating shaft, a high-order curved surface, and an aspheric surface such as an off-axis aspheric surface. According to different use scenes, one aspheric surface can replace two or more spherical surfaces to correct aberration, so that the optical structure is simplified, and miniaturization and light weight of an optical path are realized.
Compared with an aspheric surface, the free-form surface is a more complex optical structure, the curvature radius of each point on the surface is different, and the freedom degree of the surface is very high. The free curved surface not only can replace a plurality of aspheric surfaces to correct aberration, but also can improve the optical quality to the maximum extent and simplify the optical structure. The optical free-form surface has a complex structure, high degree of freedom and no clear expression definition, and is considered to be an optical free-form surface which does not have global rotational symmetry and a non-uniform optical axis and has a plurality of curvature radiuses on the whole surface.
In other embodiments of the present application, the curved mirror 37 may be a spherical mirror or an aspherical mirror, which is not limited in this application.
The cover 39 is fixedly provided to the fitting port 3122, thereby closing the first installation portion 312. The cover 39 may be connected and fixed to the first mounting portion 312 and/or the second mounting portion 314 of the housing 31 by screws, snaps, or the like.
The control part 40 is at least partially accommodated in the first accommodating space 317 and is located outside the housing 31. The control part 40 is electrically connected to the light source unit 33.
Since the control part 40 is disposed in the first accommodating space 317 of the housing 31, that is, the control part 40 and the light source unit 33 disposed in the inner cavity of the housing 31 are not disposed in the same cavity, the control part 40 does not occupy the inner space of the housing 31, which is beneficial to reducing the occupied space of the display main body 30, thus facilitating the mounting of the control part 40 and the display main body 30 in different spaces as required, and improving the mounting flexibility of the optical display 103.
The optical display 103 fully utilizes the first accommodating space 317 outside the housing 31 to provide the control part 40, reduces space waste on the bearing part 101, and improves the screen ratio of the optical display 103.
The light source unit 33 and the curved mirror 37 are fixedly accommodated in the inner cavity of the housing 31, and the housing 31, the screen 35, and the cover 39 together form a sealed optical cavity. The light source unit 33 and the curved mirror 37 are placed inside the optical cavity, and the control part 40 is located outside the optical cavity. In the physical space, the light source unit 33 and the control part 40 form a physical space isolation, and when the control part 40 needs to be replaced due to damage, the control part is convenient to be detached and replaced independently.
In addition, the control component 40 is arranged outside the shell 31, and a heat dissipation structure for dissipating heat of the control component 40 is not required to be arranged on the shell 31, so that the number of times of reflection of stray light in an optical path inside the shell 31 is reduced, the output quality of imaging light output by the display main body 30 is improved, and the display quality of the optical display 103 is improved.
In conventional optical displays, to ensure the display effect, the optical component and the control component are disposed in the same cavity, and the optical component and the control component have different design requirements (such as sealing level) for the structure, which may lead to a relatively complex structure of the optical display. In the embodiment of the present application, the control member 40 is disposed in the first accommodating space 317 outside the housing 31, so that the control member 40 and the optical element in the inner cavity of the housing 31 are structurally independent from each other, which is beneficial to simplifying the structure of the optical display 103.
In some embodiments of the present application, as shown in fig. 5b and 5c, the control component 40 includes a housing 42 and a controller 44. The housing 42 is fixedly coupled to the first mounting portion 312. The housing 42 is accommodated in the first accommodating space 317. The housing 42 serves to protect the controller 44 and reduce dust from entering the controller 44. The controller 44 is fixedly accommodated in the housing 42. The controller 44 is electrically connected to the light source unit 33, and is used for controlling the light source unit 33. The housing 42 is provided with a plurality of heat dissipation holes 422 for dissipating heat generated by the controller 44.

The pitch package 51 can provide dustproof, noise reduction, vibration resistance, impact resistance, and the like. The driving piece 52 is fixed to the outside of the pitch enclosure 51. The driver 52 is communicatively coupled to the controller 44 for actuation under the control of the controller 44. A pitch drive assembly 54 is connected between the drive member 52 and the housing 42. The pitch transmission assembly 54 is used for driving the display main body 30 to rotate around the first rotation axis under the driving of the driving element 52, so that the position of the screen 35 of the optical display 103 can be adjusted according to the positions of eyes of different users, and the user can conveniently watch the display. The pitch connection assembly 56 is connected between the first mount 312 and the second support bracket 20. Because one side of the display main body 30 is rotatably connected with the first supporting frame 10 through the pitching transmission assembly 54, and the other side of the display main body 30 is connected with the second supporting frame 20 through the pitching connection assembly 56, the use stability of the display main body 30 is improved.

The first end of the spindle 546 is fixedly coupled to the housing 42. The bearing 548 is fixed within the support 12. The rotating shaft 546 is rotatably disposed through the bearing 548, so that the rotating shaft 546 is rotatably connected to the first supporting frame 10, and the display main body 30 can rotate relative to the bearing member 101. The second end of the rotating shaft 546 exposes a side of the supporting portion 12 of the first supporting frame 10 away from the housing 42. The fixing member 549 is fixed to one end of the rotating shaft 546 to prevent the rotating shaft 546 from being separated from the first supporting frame 10.
The worm 542 is a single-head worm, and the single-head worm has a strong self-locking function, and is generally not easy to change the position of the optical display main body 30 by an external force. The spindle 546 is a spline shaft, and the worm wheel 544 and the housing 42 are provided with spline holes. The splined portion of the spindle 546 may be coupled to the splined bore of the worm gear 544 by a spline fit to achieve a fixed connection between the spindle 546 and the worm gear 544. The splined portion of the spindle 546 may be in splined engagement with the splined bore of the housing 42 to provide a secure connection between the spindle 546 and the housing 42.

In other embodiments of the present application, the control component 40 and the main motion mechanism 50 may also be disposed in the second accommodating space 318, or the control component 40 and the main motion mechanism 50 may also both be disposed in the first accommodating space 317. It is understood that the positions of the first accommodating space 317 and the second accommodating space 318 may be interchanged, or the first accommodating space 317 and the second accommodating space 318 are disposed on the same side of the first mounting portion 312.
The display main body 30 further includes a first state and a second state.

The mounting portion 14 is provided with a through hole 142 for connecting with the slide cover assembly 60.
The slide assembly 60 includes a slide movement mechanism 62 and a slide 64 coupled to the slide movement mechanism 62.

The sliding cover 64 may cover the front of the screen 35 so that the optical display 103 can be hidden inside the bearing member 101, thereby maintaining the consistency of the appearance of the bearing member 101. In addition, the cover 64 covers the screen 35 to protect the display main body 30, for example, to block light, to reduce dust, foreign substances, moisture from entering the display main body 30, to buffer impact of external force (e.g., external impact), and the like.
When the optical display 103 needs to output imaging light, the sliding cover 64 is driven by the sliding cover moving mechanism 62 to move away from the front of the screen 35, and the main moving mechanism 50 can drive the display main body 30 to move in a pitching motion, so that the screen 35 is adjusted to a position suitable for a user to watch, thereby facilitating the watching.

In some embodiments of the present application, the slider movement mechanism 62 includes a slider package 622, a slider driver 624, a slider transmission assembly 626, and a slider connection assembly 628. The sliding cover package 622 is fixed on the supporting portion 12 of the first supporting frame 10, and is used for supporting the sliding cover driving piece 624 and accommodating the sliding cover transmission assembly 626.

The fixing member 6268 is fixed to the connection shaft 6266, and the slide cover 64 is positioned between the worm wheel 6264 and the fixing member 6268 to prevent the connection shaft 6266 from being separated from the slide cover 64.
The worm 6262 is rotatable about a third axis of rotation. The worm gear 6264 is rotatable about a fourth axis of rotation. The rotational movement of the worm 6262 about the third rotational axis is converted into rotational movement of the worm wheel 6264 and the slide cover 64 about the fourth rotational axis, reducing the space occupied by the slide cover moving mechanism 62. In some embodiments of the present application, the third axis of rotation is substantially parallel to the first axis of rotation, and the second axis of rotation is substantially parallel to the fourth axis of rotation.
The worm 6262 is a single-head worm, which has a strong self-locking function, and is usually not easy to change the position of the optical sliding cover 64 by an external force. The intermediate portion of the connecting shaft 6266 is an optical shaft portion. Both ends of the connecting shaft 6266 are provided with splines. The spline of one end of the connecting shaft 6266 is spline-fitted with the worm wheel 6264, realizing a fixed connection between the connecting shaft 6266 and the worm wheel 6264. The spline at the other end of the connecting shaft 6266 is in spline fit with the slide cover 64, so that the connecting shaft 6266 and the worm wheel 6264 are fixedly connected.

One end of the connecting shaft 6286 is provided with a spline. The spline of the connecting shaft 6286 is in spline fit with the sliding cover 64, so that the connecting shaft 6286 and the sliding cover 64 are fixedly connected. By spline fit, the relative rotation of the connecting shaft 6286 and the slide cover 64 in the circumferential direction of the connecting shaft 6286 can be restricted, and the accuracy of the movement of the slide cover assembly 60 can be improved.
The sliding cover 64 includes two brackets 642 and a sliding cover 644 fixed on the two brackets 642. Two brackets 642 are used to support a slider 644. A bracket 642 is rotatably coupled to the mounting portion 14 of the first support bracket 10. The other bracket 642 is rotatably connected to the mounting portion 14 of the second bracket 20. The sliding cover 644 is used for covering the screen 35 and the opening 1017. In some embodiments of the present application, the shape of the sliding cover 644 matches the external shape of the bearing member 101, so that when the sliding cover 644 covers the opening 1017, the sliding cover 644 is matched with the external surface of the bearing member 101, and the consistency of the external appearance of the bearing member 101 is maintained.
Each bracket 642 includes a first lever portion 6422, a second lever portion 6424, and a connecting portion 6426. The first end of the first rod 6422 is fixedly connected to the sliding cover 644.

The first end of the second rod 6424 is fixedly connected to the sliding cover 644. The second lever portion 6424 can abut against the supporting portion 12 to limit the movement of the second lever portion 6424 toward the first support frame 10. The first end of the second rod 6424 and the first end of the first rod 6422 are disposed at intervals on the sliding cover 644.
Because the first end of the first rod 6422 and the first end of the second rod 6424 are fixedly connected with the sliding cover 644, the second end of the first rod 6422 and the second end of the second rod 6424 are fixedly connected with the connecting portion 6426, so that the first rod 6422, the second rod 6424 and the sliding cover 644 form a stable triangle structure, and the stability and strength of the sliding cover 64 are improved.
Further, since the first rod 6422 can abut against the supporting portion 12 and the second rod 6424 can abut against the supporting portion 12, the first rod 6422 and the second rod 6424 can limit the movement of the sliding cover 64 relative to the first supporting frame 10, thereby reducing the possibility of excessive movement of the sliding cover 64 relative to the first supporting frame 10 and limiting the rotation range of the sliding cover 64 relative to the first supporting frame 10.
The connecting portion 6426 is fixedly connected to the second end of the first rod portion 6422, and the connecting portion 6426 is fixedly connected to the second end of the second rod portion 6424.

When the sliding cover 64 is located at the first position, the included angle between the first rod portion 6422 and the supporting portion 12 is a first angle. The main movement mechanism 50 may drive the display main body 30 to rotate, and the display main body 30 may at least partially protrude out of the opening 1017 to adjust the display main body 30 to a proper posture for the user to watch. In other words, when the slide cover assembly is in the maximum open state, the display main body 30 can be switched between the first state and the second state.
In some embodiments of the present application, as shown in fig. 12, the sliding cover 64 is suspended in an intermediate position, the first rod 6422 is separated from the supporting portion 12, the second rod 6424 is separated from the supporting portion 12, the sliding cover 644 partially covers the partial opening 1017, and the sliding cover 644 can also cover a portion of the screen 35.

When the sliding cover 64 is located at the second position, the included angle between the first rod portion 6422 and the supporting portion 12 is a second angle. The first angle is greater than the second angle. The sliding cover 64 can rotate in a range of a first angle and a second angle relative to the first supporting frame 10.
Since the sliding cover 64 is located at the second position when the optical display 103 is received in the carrier 101, the sliding cover 64 covers the opening 1017 to close (block) the opening 1017, so that the outer surface of the carrier 101 and the sliding cover object 644 are spliced to form a consistent appearance surface, and the consistency of the appearance of the carrier 101 is maintained. Due to the shielding of the slide 644, the user cannot see the optical display 103 hidden inside the carrier 101.
In some embodiments of the present application, the sliding cover 64 may hover at the first position, the second position, and intermediate positions between the first position and the second position during rotation by the sliding cover movement mechanism 62.
The initial position of the slide cover 64 is set at the first position, and the optical display assembly 1003 is in an open state. Assuming that the initial state of the display main body 30 is the first state, the display main body 30 is completely accommodated in the accommodating cavity 1015 (the screen 35 is located in the accommodating cavity 1015), the sliding cover 644 does not cover the screen 35, and the opening 1017 is not blocked by the sliding cover 644. The slide cover 64 may be rotated in a first direction (e.g., clockwise) relative to the first support frame 10 by the slide movement mechanism 62. When the sliding cover 64 moves to the second position, the second rod portion 6424 abuts against the supporting portion 12, and the sliding cover 64 cannot continue to rotate along the first direction due to the limiting effect of the second rod portion 6424, the sliding cover 644 shields the screen 35 and covers the opening 1017, the opening 1017 is blocked and closed, and the optical display assembly 1003 is switched to the closed state (as shown in fig. 3).
The initial position of the slide cover 64 is set at the first position, the optical display assembly 1003 is in the open state, and the initial state of the display main body 30 is set at the first state, that is, the display main body 30 is completely accommodated in the accommodating cavity (the screen 35 is positioned in the accommodating cavity 1015), the slide cover 644 does not cover the screen 35, and the opening 1017 is not blocked by the screen 35. The display main body 30 may be driven by the main movement mechanism 50 to adjust the posture, for example, the display main body 30 is protruded outside the bearing part 101 through the opening 1017 (as shown in fig. 2), or is retracted into the receiving cavity 1015 of the bearing part 101 through the opening 1017.
As shown in fig. 2, the initial position of the slide cover 64 is set at the first position, the optical display assembly 1003 is in the open state, the initial state of the display main body 30 is set at the second state, and the screen 35 of the display main body 30 is partially located outside the bearing member 101. The display main body 30 may be driven by the main movement mechanism 50 to adjust the posture, for example, the display main body 30 may be rotated to the first state, that is, when the display main body 30 is completely accommodated in the accommodating cavity 1015 (the screen 35 is located inside the accommodating cavity 1015). The slide cover 64 may be rotated in a first direction (e.g., clockwise) relative to the first support frame 10 by the slide movement mechanism 62. When the second rod portion 6424 abuts against the supporting portion 12 (as shown in fig. 3, 13a and 13 b), the sliding cover 64 cannot continue to rotate along the first direction due to the limiting effect of the second rod portion 6424, the sliding cover 64 moves to the second position, the sliding cover 644 covers the screen 35 and the opening 1017, the opening 1017 is blocked and closed, and the optical display assembly 1003 is switched to the closed state (as shown in fig. 3).
The slider 64 is in the second position and the optical display assembly 1003 is in a closed position (as shown in fig. 3). The initial state of the display main body 30 is the first state, that is, the display main body 30 is completely accommodated in the accommodating cavity 1015 (the screen 35 is located in the accommodating cavity 1015), and the sliding cover 644 covers the screen 35 and seals the opening 1017. The slide cover 64 may be rotated in a second direction (e.g., counterclockwise) relative to the first support frame 10 by the slide movement mechanism 62. When the first rod portion 6422 abuts against the supporting portion 12 (as shown in fig. 2, 11a and 11 b), the sliding cover 64 cannot continue to rotate along the second direction due to the limiting effect of the first rod portion 6422, the sliding cover 64 moves to the first position, and the sliding cover object 644 does not cover the screen 35 and does not block the opening 1017. The display main body 30 may be driven by the main movement mechanism 50 to move to adjust the posture, for example, the display main body 30 protrudes outside the bearing member 101 through the opening 1017 or is retracted into the receiving cavity 1015 of the bearing member 101 through the opening 1017.
In other embodiments of the present application, the number of the brackets 642 is not limited, and the structure of the brackets 642 is not limited, for example, the number of the rods of the brackets 642 may be plural to improve the stability of the slide cover 64.
In one possible implementation, referring to fig. 14, the sliding cover 64 is a foldable structure (e.g., a roller shutter structure, a flexible structure), and the sliding cover 64 includes a folded state and a flat state. The sliding cover 64 is driven by the sliding cover moving mechanism, and the sliding cover 64 can be changed between a folded state and a flat state. The volume of the sliding cover 64 in the folded state is smaller than the volume of the sliding cover 64 in the flat state, and the sliding cover 64 is in the flat state when being covered by the opening, so that the sliding cover 64 occupies smaller volume of the bearing part 101 when the optical display assembly is in the open state or does not cover the screen, which is beneficial to the application of the optical display in a narrow space.
In other embodiments of the present application, referring to fig. 15, the sliding cover assembly further includes a first sensor 91 and a second sensor 93. The first sensor 91 is provided on the first support frame 10.

It is understood that the first sensor 91 may be disposed on the first lever portion 6422 and/or the first support frame 10. When the first lever 6422 contacts the first support frame 10, the first sensor 91 generates a first signal and feeds the first signal back to the control unit. The control means determines from the first signal that the slider 64 has reached the first position. A second sensor 93 is communicatively coupled to the control member, the second sensor 93 being configured to sense whether the slider 64 has reached the second position. The second sensor 93 is provided on the first support frame 10. It is appreciated that the second sensor 93 may be provided on the second lever 6424 and/or the first support frame 10. When the second lever 6424 contacts the first support frame 10, the second sensor 93 generates a second signal that is fed back to the control unit.
