Thus, the optical display 103 can be accommodated in the free space of the carrier 101, and the space utilization rate of the carrier 101 is improved.

In some embodiments of the present application, the bearing housing 1011 further includes a curved structure, and the opening 1017 is opened on the curved structure. The beam 1013 is fixedly received in the receiving cavity 1015 for supporting the optical display 103.

The control part 40 is fixed to the display main body 30 and is communicatively connected to the display main body 30. The main movement mechanism 50 is connected to the control part 40 for driving the display main body 30 to move to adjust the posture of the display main body 30 for the user's viewing. The sliding cover assembly 60 is connected to the first support 10 and the second support 20, and is used for covering the display main body 30 and closing the opening 1017, so as to hide the display main body 30 in the bearing member 101 when the display main body 30 is received in the receiving cavity 1015.

In other embodiments of the present application, the second support frame 20 may be omitted, the main moving mechanism 50 is connected between the display body 30 and the inner wall of the receiving cavity 1015, the sliding cover assembly 60 is connected with the inner wall of the receiving cavity 1015, and the sliding cover assembly 60 can move relative to the display body 30.

Referring to fig. 5a, the display main body 30 includes a housing 31, a light source unit 33, a screen 35, a curved mirror 37 and a cover 39. The light source unit 33, the screen 35, the curved mirror 37, and the cover 39 are provided on the housing 31.

The light source unit 33 is fixed to the housing 31 for emitting imaging light. A screen 35 is fixed to the housing 31 for transmitting and/or reflecting the image light. A curved mirror 37 is fixed to the housing 31 for reflecting the imaging light. A cover 39 is fixed to the housing 31 for closing the housing 31.

The imaging light emitted from the light source unit 33 is reflected to the curved mirror 37 via the screen 35, and the imaging light reflected by the curved mirror 37 is transmitted to the outside of the housing 31 via the screen 35. Among them, the light source unit 33 may be referred to as an image source. The screen 35 may reflect the image light emitted from the light source unit 33 to the curved mirror 37 and transmit the image light reflected by the curved mirror 37.

In a conventional optical display, optical elements such as a light source and a curved mirror are fixed to respective fixing frames and then assembled to a housing, so that the number of the optical display elements is large. Assembly tolerance exists in assembly between components, and if the number of components is larger, the assembly difficulty of the system or the equipment is larger, and the assembly precision can be lower.

In the present application, since the light source unit 33, the screen 35 and the curved mirror 37 are not directly fixed on the same housing 31 through other adapters (e.g., respective fixing frames), the number of components of the optical display 103 is reduced, the assembly difficulty of the optical display 103 is reduced, the assembly precision of the optical display 103 is improved, the structure of the optical display 103 is simplified, and thus, the improvement of the precision of the optical path system of the optical display 103 and the improvement of the output quality of the imaging light of the optical display 103 are facilitated.

Referring to fig. 5b and 5c, the housing 31 includes a first mounting portion 312 and a second mounting portion 314 arranged along a first direction (e.g., an X direction shown in fig. 5a, 5b and 5 c). The first mounting portion 312 is used to mount the light source unit 33. The first mounting portion 312 is provided with a fitting hole 3122 (as shown in fig. 5 c) communicating with the inner cavity of the first mounting portion 312, for facilitating the placement of the light source unit 33 into the inner cavity of the first mounting portion 312 through the fitting hole 3122.

The length of the first mounting portion 312 in the second direction (Y direction as shown in fig. 5b and 5 c) is less than the length of the second mounting portion 314 in the second direction. The second direction is different from the first direction. The outer wall of the first mounting portion 312 and the outer wall of the second mounting portion 314 jointly enclose a first accommodating space 317 and a second accommodating space 318. In the second direction, the first mounting portion 312 is located between the first accommodating space 317 and the second accommodating space 318. The first accommodating space 317 is used for accommodating the control component 40. The housing 31 is substantially T-shaped from a perspective along a third direction (the Z-direction as shown in fig. 5 b). 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 portion 314 communicates with the inner cavity of the first mounting portion 312. The second mounting portion 314 is provided with a mounting opening 3142 communicated with the inner cavity of the second mounting portion 314 for mounting the screen 35.

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 (LCD) imaging technology. The LCD imaging utilizes the photoelectric effect principle of liquid crystal, liquid crystal molecules change the arrangement state under the influence of an external electric field, and the liquid crystal molecules in different arrangement states can control the transmittance of light. For example, liquid crystal molecules are arranged between two polarizers with mutually perpendicular polarization directions, and when no electric field is applied, the liquid crystal molecules can rotate the polarization direction of linearly polarized light passing through the first polarizer by 90 degrees, and at the moment, light rays pass through the second polarizer at the maximum transmittance; when an electric field is applied, the arrangement state of the liquid crystal molecules is changed, the rotation angle of the polarized light is also changed, and the intensity of the light rays passing through the second polarizer is weakened. Each pixel point of the LCD display screen is composed of three primary colors, and the color image is displayed by controlling the intensity of the three primary colors. The light source unit 33 is not limited in the present application, and for example, the light source unit 33 may also adopt a Digital Light Processing (DLP) technology, a laser scanning projection, and the like.

The screen 35 is fixedly connected to the housing 31. The screen 35 covers the mounting opening 3142, thereby closing the second mounting portion 314. The screen 35 may be fixed to the housing 31 by glue 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 a portion of incident light incident on the screen 35 and/or reflecting a portion of the incident light, i.e., the screen 35 is a transflective optical element. For example, the screen 35 may transmit 50% of incident light, and the screen 35 may reflect 50% of 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 total incident light transmitted by the screen 35 can be selected as required. The screen 35 may be made of transparent and reflective glass.

In the present embodiment, the curved mirror 37 is a mirror that matches a free curved surface required for optical imaging.

The surface type of an 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 aberration, so that the optical structure is complex and the occupied space is large.

With the development of the optical industry, the design and manufacturing technology of aspheric surfaces with more complex surface types has been greatly improved, and aspheric surfaces generally refer to quadric surfaces such as paraboloids, ellipsoids, involute surfaces, hyperboloids and the like with rotating shafts, high-order curved surfaces, and non-rotating aspheric surfaces such as off-axis aspheric surfaces. 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 an optical structure with a more complex surface type, the curvature radiuses of all points on the surface of the free-form surface are different, and the degree of freedom of the surface type is very high. The free-form surface can not only replace a plurality of aspheric surfaces to correct aberration, but also improve the optical quality to the maximum extent and simplify the optical structure. The optical free-form surface has a complex structure and high degree of freedom, has no definite expression definition, and is generally considered as an optical free-form surface without global rotational symmetry, a uniform optical axis and a plurality of curvature radii on the whole surface.

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

The cover 39 is fixedly disposed on the fitting port 3122, and closes the first mounting portion 312. The cover 39 may be 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 cover 39 is detachably provided on the first mounting portion 312, facilitating assembly and disassembly of the light source unit 33.

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

Because the control component 40 is disposed in the first accommodating 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 inner space of the housing 31, which is beneficial to reducing the occupied space of the display main body 30, so that the control component 40 and the display main body 30 can be conveniently installed in different spaces as required, and the installation flexibility of the optical display 103 is improved.

The optical display 103 makes full use of the first accommodating space 317 outside the housing 31 to arrange the control component 40, so that the waste of space on the bearing component 101 is reduced, and the screen occupation ratio of the optical display 103 is improved.

The light source unit 33 and the curved mirror 37 are fixedly housed in an 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 unit 40 is located outside the optical cavity. In physical space, the light source unit 33 and the control component 40 form physical space isolation, and when the control component 40 needs to be replaced due to damage, the light source unit is convenient to be detached and replaced independently.

Furthermore, the control component 40 is disposed outside the housing 31, and a heat dissipation structure for dissipating heat of the control component 40 is not required to be disposed on the housing 31, so that the number of times of reflection of stray light in the optical path inside the housing 31 is reduced, which is beneficial to improving the output quality of the imaging light output by the display main body 30 and improving the display quality of the optical display 103.

In the conventional optical display, in order to ensure the display effect, the optical component and the control component are arranged in the same cavity, and the design requirements (such as sealing grade) of the optical component and the control component for the structure are different, which may lead to the structure of the optical display to be more complicated. In the embodiment of the present application, the control component 40 is disposed in the first accommodating space 317 outside the housing 31, so that the optical elements of the control component 40 and 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 connected 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 to reduce the ingress of dust into the controller 44. The controller 44 is fixedly housed within the housing 42. The controller 44 is electrically connected to the light source unit 33 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.

Referring to fig. 6 and 7, the main moving mechanism 50 is connected to a side of the housing 42 away from the first mounting portion 312, and further connected to the display main body 30 to drive the display main body 30 to rotate. The first support frame 10 and the second support frame 20 each include a support portion 12 and an installation portion 14 protruding from the support portion 12. The support portion 12 is connected with the main movement mechanism 50 to support the display main body 30 and the like.

The master motion mechanism 50 includes a pitch enclosure 51, a drive member 52, a pitch drive assembly 54, and a pitch connection assembly 56. The pitch package 51 is fixed to one end of the support portion 12 of the first support frame 10 for receiving the pitch drive assembly 54 to protect the pitch drive assembly 54. The pitching packaging shell 51 can play the roles of dust prevention, noise reduction, vibration resistance, shock resistance and the like. The driver 52 is fixed to the outside of the pitch enclosure 51. The drive member 52 is communicatively coupled to the controller 44 for actuation under the control of the controller 44. The pitch drive assembly 54 is connected between the driver 52 and the housing 42. The elevation 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 member 52, so that the position of the screen 35 of the optical display 103 can be adjusted according to the positions of the eyes of different users, and the users can watch the image conveniently. The pitch linkage assembly 56 is connected between the first mounting portion 312 and the second support bracket 20. Since one side of the display main body 30 is rotatably connected to the first support frame 10 through the pitch transmission assembly 54, and the other side of the display main body 30 is connected to the second support frame 20 through the pitch connection assembly 56, the stability of the display main body 30 is improved.

In other embodiments of the present application, the pitch enclosure 51 may be omitted and the pitch drive 52 is directly fixed to the carrier 101.

The pitch drive assembly 54 includes a first drive structure and a second drive structure connected together. The second transmission structure is connected to the housing 42, and the first transmission structure is used for driving the second transmission structure to move. In some embodiments of the present application, the first transmission structure can rotate around the second rotation axis, and the second transmission structure can drive the display main body 30 to rotate around the first rotation axis. The rotation motion of the first transmission structure around the second rotation axis is converted into the rotation motion of the second transmission structure and the display main body 30 around the first rotation axis, so that the occupied space of the main motion mechanism 50 is reduced.

In some embodiments of the present application, the first transmission structure includes a worm 542, and the worm 542 is fixedly connected to the pitch drive 52. The second gearing arrangement includes a worm gear 544, the worm gear 544 being connected to the housing 42. The worm 542 meshes with a worm gear 544. The pitch driving member 52 drives the worm 542 to rotate, and further drives the worm wheel 544 and the display main body 30 to rotate. Pitch drive assembly 54 further includes a shaft 546, a bearing 548, and a mount 549. The shaft 546 is fixedly inserted into the worm gear 544. The first end of the rotating shaft 546 is fixedly connected to the housing 42. The bearing 548 is fixed within the support portion 12. The rotating shaft 546 is rotatably disposed through the bearing 548, so that the rotating shaft 546 is rotatably connected to the first support 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 support frame 10 away from the housing 42. The fixing member 549 is fixed to one end of the rotation shaft 546 to prevent the rotation shaft 546 from being detached from the first support frame 10.

The worm 542 is a single-headed worm having a strong self-locking function, and the position of the optical display main body 30 is not easily changed by an external force under normal conditions. The rotating shaft 546 is a spline shaft, and the worm gear 544 and the housing 42 are both provided with spline holes. The splined portion of the shaft 546 and the splined bore of the worm gear 544 may be coupled by a spline fit to achieve a fixed connection between the shaft 546 and the worm gear 544. The splined portion of the shaft 546 and the splined bore of the housing 42 may be connected by a spline fit to achieve a fixed connection between the shaft 546 and the housing 42. By spline fitting, relative rotation of the rotating shaft 546 and the worm wheel 544 in the circumferential direction of the rotating shaft 546 can be restricted, and relative rotation of the rotating shaft 546 and the housing 42 in the circumferential direction of the rotating shaft 546 can be restricted, which improves the accuracy of the pitching motion of the display main body 30.

In other embodiments of the present application, the worm 542 may be a multi-thread screw, the rotating shaft 546 may be directly fixedly connected to the worm wheel 544 by a fastener, and the rotating shaft 546 may be fixedly connected to the housing 42 by a fastener.

The worm gear 544 and the worm 542 are matched to have a self-locking function, so that the display main body 30 can hover at any angle within the pitch rotation range, the position stability of the display main body 30 is improved, the position of the display main body 30 relative to the first support frame 10 can be kept stable even under the condition that the display main body 30 is vibrated continuously (for example, the vehicle 1000 runs under the bumpy road condition), the abnormal sound is not generated due to shaking, and the use reliability of the optical display 103 is improved.

Pitch connection assembly 56 includes a mounting member 565, a shaft 566, and a bearing 568. The mounting member 565 is fixed to the first mounting portion 312. One end of the shaft 566 is fixedly coupled to the mounting member 565. The bearing 568 is fixed to the second support frame 20. The end of the shaft 566 remote from the mounting member 565 is rotatably coupled to the bearing 568 to rotatably couple the display main body 30 to the second support bracket 20. The structure of the pitch connecting assembly 56 is not limited in this application, and the display main body 30 can be rotatably connected to the second support frame 20.

In other embodiments of the present application, the pitch linkage assembly 56 and the second support frame 20 may be omitted, and the display main body 30 may be supported by the first support frame 10.

In other embodiments of the present application, the pitch drive 54 is not limited in structure, for example, the pitch drive 54 includes a lead screw and a connecting member screwed with the lead screw, and the connecting member is connected to the display body 30 and/or the control member 40 in a rotation-stop manner. The driving member 52 drives the screw rod to move linearly, thereby driving the connecting member to rotate along the first rotation axis. For another example, the pitch driving component 54 may further include a gear, a driving belt (e.g., a belt), and the like, and the pitch driving component 54 may drive the display main body 30 to move relative to the bearing component 101.

In other embodiments of the present application, the pitch drive assembly 54 may be omitted from the primary motion mechanism 50, and the driving member 52 directly drives the display main body 30 to rotate.

In another embodiment of the present application, the driving member 52 may be omitted from the main movement mechanism 50, the pitch transmission unit 54 may be connected to the display main body 30, and the user may manually operate the display main body 30, the control unit 40, or other components connected to the display main body 30 to implement the pitch movement of the display main body 30.

In some possible embodiments of the present application, referring to fig. 8a, the control component 40 is disposed in the first accommodating space 317, and the main motion mechanism 50 may also be disposed in the second accommodating space 318, such that the control component 40 and the main motion mechanism 50 are disposed in different accommodating spaces, respectively, to physically separate the control component 40 and the main motion mechanism 50. In other embodiments of the present application, the control component 40 and the main movement mechanism 50 may also be disposed in the second accommodating space 318, or both the control component 40 and the main movement mechanism 50 may also 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 can 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 display main body 30 is driven by the main movement mechanism 50, and the display main body 30 can be switched between a first state and a second state. As shown in fig. 8b, when the display body 30 is in the first state, the display body 30 is completely accommodated in the accommodating cavity 1015, that is, the optical display 103 is completely accommodated in the accommodating cavity 1015. As shown in fig. 8c, when the display main body 30 is in the second state, the display main body 30 is partially received in the receiving cavity 1015, the display main body 30 partially protrudes out of the supporting component 101, the screen 35 is at least partially located outside the supporting component 101, the control component 40 and the main motion mechanism 50 are not exposed outside the supporting component 101, and the optical display 103 can present a maximum screen space ratio to a user, thereby improving the viewing experience of the user. As shown in fig. 8d, the main moving mechanism 50 drives the display main body 30 to move, and the tilt angle of the display main body 30 is adjusted, so as to adjust the posture of the display main body 30, so that the screen 35 is suitable for different positions of an eye box (eyebox) 2000 for viewing.

In other embodiments of the present application, the first support frame 10 may be omitted, and the cross member 1013 may be omitted, so as to directly connect the display main body 30 with the bearing member 101.

Referring to fig. 9 and 10, an avoiding groove 122 (as shown in fig. 10) is concavely disposed on the supporting portion 12 for accommodating a portion of the sliding cover assembly 60, so as to reduce the possibility of interference caused by the first supporting frame 10 to the movement of the sliding cover assembly 60. The mounting portion 14 is provided with a through hole 142 for connecting with the sliding cover assembly 60.

The sliding cover assembly 60 includes a sliding cover movement mechanism 62 and a sliding cover 64 connected to the sliding cover movement mechanism 62. The sliding cover moving mechanism 62 is connected to the mounting portion 14 of the first support 10 and the mounting portion 14 of the second support 20, and is used for driving the sliding cover 64 to cover the screen 35 or move away from the front of the screen 35. The sliding cover 64 can cover the front of the screen 35, so that the optical display 103 can be hidden inside the bearing part 101, thereby maintaining the appearance consistency of the bearing part 101. In addition, the sliding cover 64 covering the screen 35 can protect the display main body 30, for example, block light, reduce entry of dust, foreign substances, and moisture into the display main body 30, and buffer impact of external force (e.g., external force impact).

When the optical display 103 needs to output image 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 tilt, so that the screen 35 is adjusted to a position suitable for a user to watch, so as to facilitate the watching. Since the space occupied by the pitching motion of the display main body 30 is small, the external space of the bearing part 101 occupied by the optical display 103 in working use is reduced, and the possibility that the optical display 103 obstructs the sight of a user is reduced.

In some embodiments of the present application, the slide movement mechanism 62 includes a slide enclosure 622, a slide drive 624, a slide drive assembly 626, and a slide connection assembly 628. The sliding cover packaging case 622 is fixed on the support portion 12 of the first support frame 10 for supporting the sliding cover driving member 624 and accommodating the sliding cover transmission assembly 626. The sliding closure packaging shell 622 can play the roles of dust prevention, noise reduction, vibration resistance, shock resistance and the like. The sliding cover driving member 624 is fixed on the sliding cover enclosure 622 and located outside the sliding cover enclosure 622 for driving the sliding cover 64 to rotate relative to the first support frame 10. Slide cover drive 624 may be communicatively coupled to controller 44 to drive movement of slide cover 64 under the control of controller 44. The sliding cover transmission assembly 626 is accommodated in the sliding cover packaging shell 622. The sliding cover transmission assembly 626 is connected between the sliding cover 64 and the first support frame 10, and is used for transmitting the power of the sliding cover driving member 624 to the display main body 30, so as to enable the display main body 30 to rotate relative to the first support frame 10. The sliding cover connecting assembly 628 is connected between the second support frame 20 and the sliding cover 64, so as to rotatably connect the second support frame 20 and the sliding cover 64.

In some embodiments of the present application, the slide cover actuator assembly 626 includes a worm 6262, a worm gear 6264, a connecting shaft 6266, and a fastener 6268. The worm 6262 meshes with a worm wheel 6264. The worm gear 6264 is fixedly sleeved outside the connecting shaft 6266. The connecting shaft 6266 is fixedly connected to the slide cover 64. The connecting shaft 6266 is disposed through the through hole 142 and is in clearance fit with the inner wall of the through hole 142, so that the connecting shaft 6266 is rotatably connected with the mounting portion 14 of the first support frame 10. The fixing member 6268 is fixed to the connecting shaft 6266, and the sliding cover 64 is positioned between the worm gear 6264 and the fixing member 6268 to prevent the connecting shaft 6266 from being detached from the sliding 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 rotation of the worm 6262 about the third rotation axis is converted into the rotation of the worm wheel 6264 and the slide cover 64 about the fourth rotation axis, thereby reducing the space occupied by the slide cover movement 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-headed worm having a strong self-locking function, and the position of the optical sliding cover 64 is not easily changed by an external force in a normal case. The connecting shaft 6266 has an optical axis portion at its middle portion. Both ends of the connecting shaft 6266 are provided with splines. Splines at one end of the connecting shaft 6266 are in spline fit with the worm wheel 6264, so that the connecting shaft 6266 and the worm wheel 6264 are fixedly connected. The spline at the other end of the connecting shaft 6266 is in spline fit with the sliding cover 64, so that the connecting shaft 6266 and the worm wheel 6264 are fixedly connected. Through spline fit, relative rotation of the connecting shaft 6266 and the worm wheel 6264 in the circumferential direction of the connecting shaft 6266 and relative rotation of the connecting shaft 6266 and the sliding cover 64 in the circumferential direction of the rotating shaft 546 can be limited, and the precision of movement of the sliding cover assembly 60 is improved.

In other embodiments of the present application, the connecting shaft 6266 may be directly fixedly connected to the worm wheel 6264 by a fastener, and the connecting shaft 6266 may be fixedly connected to the sliding cover 64 by a fastener. The worm 6262 may be a multi-start screw.

The worm wheel 6264 and the worm 6262 are matched to have a self-locking function, so that the sliding cover 64 can hover at any angle within a rotation range, the position stability of the sliding cover 64 is improved, the position of the sliding cover 64 relative to the first support frame 10 can be kept stable even under the condition that the sliding cover 64 is vibrated continuously (for example, the vehicle 1000 runs under a bumpy road condition), abnormal sound is not generated due to shaking, and the use reliability of the optical display 103 is improved.

The sliding cover connecting assembly 628 includes a connecting shaft 6286 and a fixing member 6288. The connecting shaft 6286 is rotatably connected to the second support bracket 80. 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 is fixedly connected with the sliding cover 64. Through spline fit, relative rotation of the connecting shaft 6286 and the sliding cover 64 in the circumferential direction of the connecting shaft 6286 can be limited, and the movement accuracy of the sliding cover assembly 60 is 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 pivotally connected to the mounting portion 14 of the first support bracket 10. The other bracket 642 is pivotally connected to the mounting portion 14 of the second support bracket 20. The sliding cover 644 is used for covering the screen 35 and covering the opening 1017. In some embodiments of the present application, the shape of the sliding cover 644 matches the external shape of the carrier 101, so that when the sliding cover 644 covers the opening 1017, the sliding cover 644 fits the external surface of the carrier 101, and the external appearance of the carrier 101 is kept consistent.

Each bracket 642 includes a first rod portion 6422, a second rod portion 6424, and a connecting portion 6426. The first end of the first rod portion 6422 is fixedly connected to the sliding cover 644. The first rod portion 6422 can abut against the support portion 12 to limit the movement of the first rod portion 6422 toward the first support frame 10. The first end of the second rod portion 6424 is fixedly connected to the sliding cover 644. The second rod portion 6424 can abut against the support portion 12 to limit the movement of the second rod portion 6424 toward the first support frame 10. The first end of the second rod portion 6424 is spaced apart from the first end of the first rod portion 6422 on the slide 644.

Because the first end of the first rod portion 6422 and the first end of the second rod portion 6424 are fixedly connected to the sliding cover 644, and the second end of the first rod portion 6422 and the second end of the second rod portion 6424 are fixedly connected to the connecting portion 6426, the first rod portion 6422, the second rod portion 6424 and the sliding cover 644 form a stable triangular structure, and the stability and strength of the sliding cover 64 are improved.

Furthermore, since the first rod part 6422 can abut against the support part 12 and the second rod part 6424 can abut against the support part 12, the first rod part 6422 and the second rod part 6424 can limit the movement of the sliding cover 64 relative to the first support frame 10, thereby reducing the possibility of excessive movement of the sliding cover 64 relative to the first support frame 10 and limiting the rotation range of the sliding cover 64 relative to the first support 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. The connecting portion 6426 is partially received in the avoiding groove 122. In some embodiments of the present application, the connecting shaft 6266 is disposed through the mounting portion 14 and exposed out of the avoiding groove 122. The mounting portion 14 of the first support bracket 10 is located between the connecting portion 6426 and the worm wheel 6264.

The sliding cover 64 includes a first position (shown in fig. 2, 11a and 11 b), an intermediate position (shown in fig. 12) and a second position (shown in fig. 3, 13a and 13 b). When the sliding cover 64 is located at the first position, the sliding cover assembly 60 is in a maximum state that can be opened relative to the first support frame 10, and the optical display assembly 1003 is in an open state. When the sliding cover 64 is located at the second position, the sliding cover 64 covers the opening 1017, and the optical display assembly 1003 is in a closed state. The intermediate position is any position in which the slide cover 64 is rotated between the first position and the second position.

In some embodiments of the present application, please refer to fig. 2, 11a and 11b in combination, the sliding cover 64 is located at the first position, the first rod portion 6422 abuts against the supporting portion 12, the second rod portion 6424 is separated from the supporting portion 12, the sliding cover 644 does not cover the screen 35, the sliding cover 644 does not cover the opening 1017, that is, the opening 1017 is not blocked and closed, and the imaging light emitted from the screen 35 can be emitted to the outside of the bearing component 101. When the sliding cover 64 is located at the first position, an included angle between the first rod portion 6422 and the supporting portion 12 is a first angle. The main movement mechanism 50 can drive the display main body 30 to rotate, and the display main body 30 can 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 64 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 at an intermediate position, the first rod portion 6422 is separated from the supporting portion 12, the second rod portion 6424 is separated from the supporting portion 12, a portion of the sliding cover 644 covers a portion of the opening 1017, and the sliding cover 644 can also cover a portion of the screen 35.

In some embodiments of the present application, please refer to fig. 3, 13a and 13b in combination, the sliding cover 64 is located at the second position, the second rod portion 6424 abuts against the supporting portion 12, the first rod portion 6422 is separated from the supporting portion 12, the sliding cover 644 completely covers the screen 35, the sliding cover 644 completely covers the opening 1017 to block the opening 1017, that is, the optical display 103 is accommodated and hidden in the supporting member 101. 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 relative to the first support frame 10 by a difference between the first angle and the second angle.

Because the sliding cover 64 is located at the second position when the optical display 103 is accommodated 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 644 are spliced into a uniform appearance surface, and the appearance uniformity of the carrier 101 is maintained. Due to the shielding of the sliding cover 644, the user cannot see the optical display 103 hidden inside the carrying component 101.

In some embodiments of the present application, the sliding cover 64 can hover at the first position, the second position, and an intermediate position between the first position and the second position during rotation by the sliding cover movement mechanism 62.

Assuming that the initial position of the slide cover 64 is at the first position, 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 driven by the slide cover movement mechanism 62 to rotate relative to the first support frame 10 in a first direction (e.g., clockwise). When the sliding cover 64 moves to the second position, the second rod portion 6424 abuts against the supporting portion 12, due to the limiting function of the second rod portion 6424, the sliding cover 64 cannot rotate continuously along the first direction, the sliding cover 644 covers the screen 35 and covers the opening 1017, the opening 1017 is sealed and closed, and the optical display device 1003 is switched to the closed state (as shown in fig. 3).

Assuming that the initial position of the sliding cover 64 is located 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 the first state, that is, the display main body 30 is completely accommodated in the accommodating cavity (the screen 35 is located inside the accommodating cavity 1015), the sliding cover 644 does not cover the screen 35, and the opening 1017 is not blocked by the screen 35. The display body 30 can be driven by the main motion mechanism 50 to adjust the posture, for example, the display body 30 extends out of the outer portion of the bearing part 101 through the opening 1017 (as shown in fig. 2), or retracts into the receiving cavity 1015 of the bearing part 101 through the opening 1017.

As shown in fig. 2, the initial position of the sliding cover 64 is set to the first position, the optical display assembly 1003 is in the open state, the initial state of the display main body 30 is set to 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 can be driven by the main motion mechanism 50 to adjust the posture, for example, the display main body 30 rotates to a first state, that is, when the display main body 30 is completely received in the receiving cavity 1015 (the screen 35 is located inside the receiving cavity 1015). The slide cover 64 may be driven by the slide cover movement mechanism 62 to rotate relative to the first support frame 10 in a first direction (e.g., clockwise). When the second rod portion 6424 abuts against the support portion 12 (as shown in fig. 3, 13a and 13 b), due to the limit function of the second rod portion 6424, the sliding cover 64 cannot rotate continuously along the first rotation direction, the sliding cover 64 moves to the second position, the sliding cover 644 covers the screen 35 and covers the opening 1017, the opening 1017 is sealed and closed, and the optical display device 1003 is switched to the closed state (as shown in fig. 3).

The slide cover 64 is in the second position and the optical display assembly 1003 is in a closed state (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 received in the receiving cavity 1015 (the screen 35 is located in the receiving cavity 1015), and the sliding cover 644 covers the screen 35 and blocks the opening 1017. The slide cover 64 may be driven by the slide cover movement mechanism 62 to rotate relative to the first support frame 10 in a second rotational direction (e.g., counterclockwise). When the first rod portion 6422 abuts against the support portion 12 (as shown in fig. 2, 11a and 11 b), due to the limiting function of the first rod portion 6422, the sliding cover 64 cannot rotate continuously along the second rotation direction, the sliding cover 64 moves to the first position, and 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 motion mechanism 50 to move to adjust the posture, for example, the display body 30 extends out of the bearing part 101 through the opening 1017, or retracts into the receiving cavity 1015 of the bearing part 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 rod portion of the bracket 642 may be multiple to improve the stability of the sliding cover 64.

In one possible implementation manner, 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 slide cover 64 is driven by the slide movement mechanism, and the slide 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 that of the sliding cover 64 in the flat state, and the sliding cover 64 is in the flat state when covering the opening, so that the sliding cover 64 occupies a 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 another embodiment 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. The first sensor 91 is communicatively connected to the control unit, and the first sensor 91 is used for sensing whether the slide cover 64 reaches the first position. It is understood that the first sensor 91 may be provided on the first shaft portion 6422 and/or the first support bracket 10. When the first rod portion 6422 contacts the first support frame 10, the first sensor 91 generates a first signal and feeds the first signal back to the control component. The control component determines that the slide cover 64 reaches the first position based on the first signal. A second sensor 93 is in communication with the control unit, the second sensor 93 being adapted to sense whether the slide cover 64 has reached the second position. The second sensor 93 is provided on the first support frame 10. It is understood that the second sensor 93 may be disposed on the second shaft portion 6424 and/or the first support bracket 10. When the second rod portion 6424 is in contact with the first support frame 10, the second sensor generates a second signal that is fed back to the control component. The control component determines that the slide cover 64 reaches the second position based on the second signal. The first sensor 91 may be a sensing device such as a micro switch or an infrared detector, and the second sensor 93 may be a sensing device such as a micro switch or an infrared detector.
