Referring to fig. 2, 3 and 4, the carrier 101 includes a carrier housing 1011 and a cross beam 1013. The carrier housing 1011 is used to support a meter, such as a speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charge gauge, and the like.

The opening 1017 is used to expose the optical display 103 received in the receiving cavity 1015. Thus, the optical display 103 can be accommodated in the spare space of the carrier 101, and the space utilization of the carrier 101 can be improved.

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

In other embodiments of the present application, the opening 1017 of the bearing shell 1011 may not be disposed on the curved surface structure, the bearing shell 1011 may not include the curved surface structure, and the structure and shape of the bearing shell 1011 are not limited.

The optical display 103 includes a first support frame 10, a second support frame 20, a display main body 30, a control part 40, a main movement mechanism 50, and a slide cover assembly 60. The first support frame 10 and the second support frame 20 are fixedly contained in the containing cavity 1015, the first support frame 10 is fixedly connected with the cross beam 1013, the second support frame 20 is fixedly connected with the cross beam 1013, and the first support frame 10 and the second support frame 20 are used for supporting the display main body 30 and other components. The display main body 30 is supported by the first support frame 10 and the second support frame 20 and can be accommodated in the accommodating cavity 1015. 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 so as to adjust the posture of the display main body 30 for the user to watch. The sliding cover assembly 60 is connected to the first supporting frame 10 and the second supporting frame 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 component 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 movement mechanism 50 is connected between the display main 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 main body 30.

In some embodiments of the present application, optical display assembly 1003 includes an open state (as shown in fig. 2), a closed state (as shown in fig. 3), and a semi-open state (as shown in fig. 1). When the optical display assembly 1003 is in the open state, the opening 1017 is not covered (blocked) by the slide cover assembly 60, and the display main body 30 can extend out of the bearing member 101 from the opening 1017 or retract into the accommodating cavity 1015 from the opening 1017 under the driving of the main movement mechanism 50.

The semi-open state of the optical display assembly 1003 is between an open state and a closed state. When the optical display assembly 1003 is in the half-open state, the opening 1017 is partially blocked by the slide cover assembly 60, and the optical display 103 is accommodated in the carrier 101.

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 secured to the housing 31 for transmitting and/or reflecting imaging 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 through the screen 35, and the imaging light reflected by the curved mirror 37 is transmitted to the outside of the housing 31 through the screen 35. Among them, the light source unit 33 may be referred to as an image source. The screen 35 may reflect the imaging light emitted from the light source unit 33 to the curved mirror 37, and transmit the imaging 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 fixed frames and then assembled to a housing, so that the number of the optical display elements is large. Assembly tolerances exist in assembly between components, and if the number of components is larger, the assembly difficulty of the system or the device is larger, and the assembly accuracy may be lower.

In this 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 connectors (such as 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 further, the precision of the optical path system of the optical display 103 is advantageously improved, and the output quality of the imaging light of the optical display 103 is improved.

Referring to fig. 5b and 5c in combination, the housing 31 includes a first mounting portion 312 and a second mounting portion 314 aligned along a first direction (e.g., an X direction shown in fig. 5a, 5b, and 5 c). The first mounting portion 312 is for mounting the light source unit 33. The first mounting portion 312 is provided with a fitting port 3122 (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 port 3122.

The length of the first mounting portion 312 in the second direction (Y direction as shown in fig. 5b and 5 c) is smaller 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 together 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 part 40. From a perspective in a third direction (Z direction as shown in fig. 5 b), the shape of the housing 31 is substantially 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 interior cavity of the second mounting portion 314 communicates with the interior cavity of the first mounting portion 312. The second mounting portion 314 is provided with a mounting port 3142 communicating 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 (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 cover 39 is detachably provided on the first mounting portion 312, facilitating assembly and disassembly of the light source unit 33.

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.

Referring to fig. 6 and 7, the main movement 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, so as 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 to the main movement mechanism 50 to support the display main body 30 and the like.

The primary motion mechanism 50 includes a pitch enclosure 51, a drive 52, a pitch drive assembly 54, and a pitch link assembly 56. The pitch package 51 is fixed to one end of the supporting portion 12 of the first support frame 10, and is configured to receive the pitch transmission assembly 54 to protect the pitch transmission assembly 54. 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.

In other embodiments of the present application, the pitch enclosure 51 may be omitted, with the pitch drive 52 being directly secured to the carrier 101.

The pitch drive assembly 54 includes a first drive structure and a second drive structure that are connected. The second transmission structure is connected with the casing 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 is capable of rotating about the second rotation axis, and the second transmission structure may drive the display main body 30 to rotate about the first rotation axis. By converting the rotational movement of the first transmission structure about the second rotational axis into the rotational movement of the second transmission structure and the display body 30 about the first rotational axis, the occupation space of the main movement mechanism 50 is reduced.

In some embodiments of the present application, the first transmission structure includes a worm 542, the worm 542 being fixedly connected to the pitch drive 52. The second transmission structure includes a worm gear 544, the worm gear 544 being coupled to the housing 42. The worm 542 meshes with a worm wheel 544. The pitching 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 also includes a shaft 546, a bearing 548 and a mount 549. The rotating shaft 546 is fixedly arranged through the worm wheel 544. 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. By spline fitting, the relative rotation of the rotating shaft 546 and the worm wheel 544 in the circumferential direction of the rotating shaft 546 and the relative rotation of the rotating shaft 546 and the housing 42 in the circumferential direction of the rotating shaft 546 can be restricted, and the accuracy of the pitching motion of the display main body 30 can be improved.

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

The cooperation between worm wheel 544 and worm 542 possesses the self-locking function, can realize that display main body 30 can hover at any angle in the every single move rotation scope, has improved display main body 30's position stability, even under the condition that display main body 30 is constantly vibrated (for example vehicle 1000 is traveling under the road conditions of jolting), still can keep display main body 30's position stability relative to first support frame 10, and does not rock and produce abnormal sound, has improved the reliability of use of optical display 103.

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

In other embodiments of the present application, the pitch connection 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 assembly 54 is not limited in structure, and for example, the pitch drive assembly 54 includes a screw and a connecting member screwed with the screw, and the connecting member is in anti-rotation connection with the display main body 30 and/or the control part 40. The driving member 52 drives the screw rod to perform linear motion, and further drives the connecting member to rotate along the first rotation axis. For another example, the pitch drive assembly 54 may further include gears, a belt (e.g., a belt), etc., where the pitch drive assembly 54 may move the display body 30 relative to the carrier 101.

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

In other embodiments of the present application, the driving member 52 may be omitted from the main movement mechanism 50, and the pitch transmission assembly 54 may be connected to the display main body 30, so that a user may manually operate the display main body 30 or the control member 40, etc. 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, so that the control component 40 and the main motion mechanism 50 are disposed in different accommodating spaces respectively, so as 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 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 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 main body 30 is in the first state, the display main 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, a portion of the display main body 30 is accommodated in the accommodating cavity 1015, a portion of the display main body 30 protrudes out of the bearing member 101, the screen 35 is at least partially located outside the bearing member 101, the control member 40 and the main movement mechanism 50 are not exposed outside the bearing member 101, and the optical display 103 can present the maximum screen occupation ratio to the user, so that the viewing experience of the user is improved. As shown in fig. 8d, the main movement mechanism 50 drives the display main body 30 to move, so as to adjust the pitch angle of the display main body 30, thereby adjusting the posture of the display main body 30, so that the screen 35 is suitable for different positions of eye boxes (eyeboxes) 2000, and is convenient 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, directly connecting the display main body 30 with the carrier 101.

Referring to fig. 9 and 10, the support portion 12 is concavely provided with a recess 122 (as shown in fig. 10) for accommodating a portion of the slide assembly 60, so as to reduce the possibility of interference of the first support frame 10 on the movement of the slide assembly 60. 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 moving mechanism 62 is connected to the mounting portion 14 of the first support frame 10 and the mounting portion 14 of the second support frame 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 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. Since the space occupied by the tilting movement of the display main body 30 is small, the external space of the bearing member 101 occupied by the optical display 103 during working use is reduced, and the possibility that the optical display 103 obstructs the vision of the user is reduced.

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 cover-slip package 622 can have dustproof, noise-reducing, vibration-resisting, shock-resisting effects, etc. The sliding cover driving piece 624 is fixed on the sliding cover package 622 and located outside the sliding cover package 622, and is used for driving the sliding cover 64 to rotate relative to the first support frame 10. The slider driver 624 may be communicatively coupled to the controller 44 to drive movement of the slider 64 under the control of the controller 44. The slider driving assembly 626 is accommodated in the slider package 622. The sliding cover transmission assembly 626 is connected between the sliding cover 64 and the first supporting frame 10, and is used for transmitting the power of the sliding cover driving piece 624 to the display main body 30, so as to realize the rotation of the display main body 30 relative to the first supporting frame 10. The sliding cover connecting assembly 628 is connected between the second support frame 20 and the sliding cover 64, so as to realize the rotational connection between the second support frame 20 and the sliding cover 64.

In some embodiments of the present application, the slider drive assembly 626 includes a worm 6262, a worm gear 6264, a connecting shaft 6266, and a securing member 6268. The worm 6262 is engaged with the 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 as to realize the rotational connection between the connecting shaft 6266 and the mounting portion 14 of the first support frame 10. 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. By spline fit, the relative rotation of the connecting shaft 6266 and the worm wheel 6264 in the circumferential direction of the connecting shaft 6266 and the relative rotation of the connecting shaft 6266 and the sliding cover 64 in the circumferential direction of the rotating shaft 546 can be restricted, and the accuracy of the movement of the sliding cover assembly 60 can be improved.

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

The cooperation between the worm wheel 6264 and the worm 6262 has a self-locking function, so that the sliding cover 64 can hover at any angle within the rotation range, the position stability of the sliding cover 64 is improved, the position stability of the sliding cover 64 relative to the first support frame 10 can be maintained even if the sliding cover 64 is continuously vibrated (for example, the vehicle 1000 runs under a bumpy road condition), abnormal noise 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 supporting frame 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 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 lever portion 6422 can abut against the support portion 12 to limit movement of the first lever portion 6422 toward the first support frame 10. 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. The connection portion 6426 is partially accommodated in the escape 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 relief groove 122. The mounting portion 14 of the first support frame 10 is located between the connecting portion 6426 and the worm gear 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 slide cover 64 is at the first position, the slide cover assembly 60 is at the maximum openable state relative to the first support frame 10, and the optical display assembly 1003 is at the opened state. When the sliding cover 64 is at the second position, the sliding cover 64 is covered on the opening 1017, and the optical display assembly 1003 is in a closed state. The intermediate position is any position where the slide cover 64 rotates between the first position and the second position.

In some embodiments of the present application, referring to fig. 2, 11a and 11b, the sliding cover 64 is located at the first position, the first rod portion 6422 is propped 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, i.e. the opening 1017 is not blocked and closed, and the imaging light emitted from the screen 35 can be emitted out of the bearing member 101. 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 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 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.

In some embodiments of the present application, referring to fig. 3, fig. 13a and fig. 13b, the sliding cover 64 is located at the second position, the second rod portion 6424 is abutted 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, and the sliding cover 644 completely covers the opening 1017 to block the opening 1017, i.e. the optical display 103 is received and hidden in the bearing 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 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 is 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. The first sensor 91 is communicatively connected to the control member, the first sensor 91 being adapted to sense whether the slide cover 64 has reached the first position. 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 generates a second signal that is fed back to the control unit. The control means determines from the second signal that the slider 64 has reached the second position.
