In the related art, the optical display includes a window piece, an image source screen, a curved mirror and a shell. The shell has a first opening and a second opening. The window piece covers the first opening and is connected to the shell. The image source screen covers the second opening and is connected to the shell.

However, the window area in the window piece for transmitting the imaging beam to the outside of the optical cavity is small, which reduces the display area of ​​the optical display. Utility Model Content

[0003] The embodiments of the present application provide an optical display, a display device, and a vehicle, which can reduce the shielding area, thereby increasing the area of ​​the window area, and further increasing the display area of ​​the optical display.

[0004] In a first aspect, the present application provides an optical display, comprising a window component, an image source component, a middle shell and a metal support component. The image source component is connected to the first end of the middle shell, the metal support component is bonded to the edge of the window component and connected to the second end of the middle shell, and the middle shell, the image source component, the window component and the metal support component together form an optical cavity for accommodating an imaging light beam emitted by the image source component. The window component has a window area and a shielding area, the shielding area surrounds the window area, the window area is used to transmit the imaging light beam inside the optical cavity to the outside, along the first direction, the projection of the window area does not overlap with the metal support component, and the projection of the shielding area covers the area of ​​the metal support component opposite to the window component in the first direction. The first direction is defined as the thickness direction of the window component.

[0005] By supporting the window part through the metal bracket, the width of the area where the metal bracket and the window part are opposite can be reduced on the basis of meeting the safety of airbag explosion. At the same time, the metal bracket is connected to the window part by bonding, and on the basis of ensuring the reliability of the connection between the window part and the metal bracket, the bonding area between the metal bracket and the window part can be reduced, so that the shielding area is reduced. Therefore, the window part is connected to the middle shell through the metal bracket and connected to the metal bracket by bonding, which can reduce the area where the window part and the metal bracket are opposite, thereby reducing the width of the shielding area and increasing the area of ​​the window area, thereby realizing an extremely narrow black border design and increasing the display area of ​​the optical display. In addition, the metal bracket has high strength, and during the airbag explosion process, the metal bracket is not easy to deform, so that the bonding between the metal bracket and the window part is not easy to fail, thereby avoiding the separation of the window part and the metal bracket and preventing secondary damage to the user.

[0007] In this way, the bonding area between the metal bracket component and the window component can be increased, which helps to further improve the connection strength between the window component and the metal bracket component.

[0008] In a possible implementation, along the second direction, the projection of the annular frame portion covers the window member, wherein the first direction is perpendicular to the second direction.

[0011] In this way, by covering the side wall of the window member with the front shell, the window member can be prevented from being damaged, and the appearance refinement of the optical display can be improved. In addition, the material of the front shell can be plastic or plastic, which is easy to shape and can more easily meet the modeling requirements. In addition, when the front shell is made of non-metallic materials, the weight of the optical display can be reduced.

[0012] In a possible implementation, the projection of the front shell in the first direction covers the annular frame portion, and the projection of the front shell in the second direction covers the metal bracket member.

[0013] In this way, the metal bracket can be covered to prevent the metal bracket from leaking out, which can improve the appearance refinement of the optical display. At the same time, using the front shell to cover the metal bracket can expand the application range of the front shell and reduce the number of parts of the optical display.

[0014] In a possible implementation, the window piece includes a window element and an annular shielding layer, the shielding layer is disposed between the window element and the metal support element, the shielding layer is fixedly connected to the window element and bonded to the metal support element, and the shielding layer is used to form a shielding area.

[0015] In this way, the shielding layer can divide the window part into a window area and a shielding area, and can cover the connection between the window part and the metal bracket part to prevent users from seeing it, thereby improving the refinement of the appearance.

[0016] In a possible implementation, the optical display further includes an adhesive component, the window component is fixedly connected to the metal bracket component via the adhesive component, and the projection of the shielding area in the first direction covers the adhesive component.

[0017] In this way, the window member and the metal bracket member can be firmly connected while the width of the metal bracket member is reduced.

[0018] In a possible implementation manner, the window member and the metal bracket member form a receiving portion, and the receiving portion is used to receive glue for bonding the window member and the metal bracket member.

[0062] Figure 1 is a front schematic diagram of an optical display in the related art, Figure 2 for Figure 1 A schematic cross-sectional view of an optical display shown in FIG. Figure 3 for Figure 1 Schematic diagram of the optical display cooperating with the airbag.

[0063] In the related art, see Figure 1 and Figure 2 As shown, the optical display 101 includes a window member 102, an image source screen 103, a curved mirror 104 and a housing 105. The housing 105 has a first opening and a second opening, the window member 102 covers the first opening and is connected to the housing 105, the image source screen 103 covers the second opening and is connected to the housing 105, the housing 105, the window member 102 and the image source screen 103 together form an optical cavity 106, and the curved mirror 104 is disposed inside the optical cavity 106. The image source screen 103 is used to emit an imaging light beam toward the window member 102, the window member 102 is used to reflect the imaging light beam to the curved mirror 104 and to transmit the imaging light beam reflected by the curved mirror 104 to the outside of the optical cavity 106, and the curved mirror 104 is used to reflect the imaging light beam from the window member 102. The window piece 102 includes a black border area 1022 and a window area 1021. The black border area 1022 is annular and surrounds the window area 1021. The window area 1021 is used to transmit the imaging light beam reflected by the curved mirror 104 to the outside of the optical cavity 106. The black border area 1022 is used to cover the area where the edge of the window piece 102 is opposite to the housing 105 to improve the appearance refinement of the optical display 101.

[0064] When the optical display 101 is installed near the airbag 107, for example, the optical display 101 is installed on the dashboard of the car facing the passenger seat, after the airbag 107 explodes, Figure 3 As shown, the airbag 107 will impact the optical display 101. In order to achieve the safety of the explosion of the airbag 107 and to prevent the window member 102 from causing secondary damage to the user, in one embodiment, the housing 105 and the window member 102 are in the thickness direction of the window member 102 (such as Figure 2 The overlapping area in the Y direction (shown in FIG. 1 ) is larger, so that the width of the portion of the housing 105 that faces the window member 102 is larger, ensuring that the housing 105 has sufficient strength.

[0065] However, the overlapping area between the housing 105 and the window member 102 is relatively large, so that the width of the black border area 1022 covering the area opposite to the window member 102 and the housing 105 is relatively large, resulting in a smaller window area 1021, which reduces the display area of ​​the optical display 101. Therefore, how to increase the display area of ​​the optical display 101 becomes a problem to be solved urgently.

[0066] In view of this, the embodiment of the present application provides an optical display 300, a display device and a vehicle 100, wherein the window member 10 in the optical display 300 is connected to the metal bracket member 50 by bonding, and the metal bracket member 50 resists the impact force generated by the airbag, so that the airbag explosion safety can be achieved. At the same time, by bonding to ensure the connection strength between the window member 10 and the metal bracket member 50, the width of the shielding area 12 can be reduced, thereby increasing the area of ​​the window area 11, and further increasing the display area of ​​the optical display 300.

[0067] The vehicle 100 provided in the embodiment of the present application may include but is not limited to known vehicles 100 such as cars, airplanes, ships, trains, etc. In addition, the vehicle 100 provided in the embodiment of the present application may also be a new vehicle 100 that will appear in the future.

[0068] The car may be an electric car, a fuel car or a hybrid car, such as a pure electric car, an extended-range electric car, a new energy car, a fuel cell car, a hybrid electric car, etc. For example, in the embodiment of the present application, the car is taken as the above-mentioned transportation tool 100 for explanation.

[0069] Figure 4 A schematic diagram of the structure of a vehicle provided in an embodiment of the present application.

[0070] See also Figure 4 As shown, the vehicle 100 includes a vehicle body 200 and an optical display 300. The optical display 300 is installed on the vehicle body 200. The vehicle body 200 includes seats, a dashboard and vehicle lights.

[0071] Exemplarily, the optical display 300 is installed in the instrument panel, and the optical display 300 is located in front of the co-pilot position. Of course, the optical display 300 can also be installed in other positions, such as a seat.

[0072] It should be noted that the optical display 300 provided in the embodiment of the present application can be applied to other devices in addition to being applied to the vehicle 100. In some implementations, the optical display 300 can also be applied to display devices such as head-up display (HUD), projector, television, near eye display (NED) device, etc.

[0073] The specific type of the NED device is not limited here, for example, it may be an AR device or a VR device, the AR device may include but is not limited to AR glasses or an AR helmet, and the VR device may include but is not limited to VR glasses or a VR helmet.

[0074] Among them, the types of HUD include but are not limited to windshield (W)-HUD, augmented reality head-up display (AR-HUD), etc.

[0075] In some other implementations, the optical display 300 may also be used in medical equipment, office entertainment equipment, industrial control equipment, and the like, without specific limitation herein.

[0076] The implementation method of the optical display 300 provided in the embodiment of the present application is described below.

[0077] Figure 5 A cross-sectional schematic diagram of a first optical display provided in an embodiment of the present application, Figure 6 for Figure 5 Enlarged schematic diagram of point H in the middle.

[0078] See also Figure 5 As shown, the optical display 300 includes a window member 10, an image source member 20, a housing assembly 40 and a curved mirror 30. The image source member 20 is connected to a first end of the housing assembly 40, the window member 10 is connected to a second end of the housing assembly 40, the window member 10, the housing assembly 40 and the image source member 20 together form an optical cavity A, and the curved mirror 30 is disposed inside the housing assembly 40 and fixedly connected to the housing assembly 40. The image source member 20 is used to emit an imaging light beam (such as Figure 5 The imaging light beam is used to generate an image. The window member 10 is used to reflect the imaging light from the image source member 20 to the curved mirror 30, and to transmit the imaging light beam from the curved mirror 30 to the outside of the optical cavity A. The curved mirror 30 is used to reflect the imaging light beam from the window member 10 to the window member 10.

[0079] See also Figure 5 As shown, during the operation of the optical display 300, the image source element 20 emits an imaging light beam (such as Figure 5The inner surface of the window member 10 reflects the imaging light beam to the surface of the curved mirror 30, and the curved mirror 30 reflects the imaging light beam to the inner surface of the window member 10. The imaging light beam reflected by the curved mirror 30 passes through the inner surface of the window member 10 and is emitted from the outer surface of the window member 10 to the outside of the optical cavity A. The imaging light beam outside the optical cavity A will enter the eye, and the eye can see a magnified virtual image.

[0080] The virtual image can be viewed by the eye without being received by a light screen. Figure 5 As shown, the image source 20 emits an imaging light beam with a certain divergence angle, which enters the eye after being reflected by the window 10 and the curved mirror 30. The brain will trace the light beam in reverse based on the experience that "light travels in a straight line" and consider the intersection of the imaging light beam with the reverse extension as the object point, that is, the virtual image point. The position of the eye can be called the eyebox position. Figure 5 As shown, the imaging light beam includes an imaging light beam L1 and an imaging light beam L2 , and the two imaging light beams limit the divergence angle of the light emitted by the image source device 20 .

[0081] It should be noted that Figure 5 The optical path shown is a schematic diagram, and other optical path schemes are also possible to achieve virtual image display, which are not described here one by one.

[0082] In some implementations, the imaging light beam transmitted by the window member 10 to the outside of the optical display 300 may also be emitted onto a light curtain (not shown in the figure) located outside the optical display 300. The light curtain may be a wall, a projection screen, a template, etc., and the specific form of the light curtain is not limited here.

[0083] In the embodiment of the present application, the specific structure of the curved mirror 30 is not shown here. The curved mirror 30 can be a free-form reflector, a spherical reflector, or an aspherical reflector.

[0084] See also Figure 5 and Figure 6 As shown, the housing assembly 40 includes a middle shell 60 and a metal bracket 50. The first end of the middle shell 60 is connected to the image source component 20, the second end of the middle shell 60 is connected to the metal bracket 50, the metal bracket 50 is bonded to the edge of the window component 10, and the window component 10 is connected to the second end of the middle shell 60 through the metal bracket 50. The middle shell 60, the image source component 20, the window component 10 and the metal bracket 50 together form an optical cavity A for accommodating the imaging light beam emitted by the image source component 20.

[0085] Continue to see Figure 5As shown, the middle shell 60 has a first opening 61 and a second opening 62. The image source component 20 is disposed at the first opening 61 and covers the first opening 61, and the image source component 20 emits an imaging light beam to the window component 10 through the first opening 61. The window component 10 and the metal bracket component 50 are both disposed at the second opening 62, and the window component 10 can reflect or transmit the imaging light beam through the second opening 62.

[0086] In some implementations, see Figure 5 As shown, the image source component 20 is disposed outside the middle shell 60. In other implementations, the image source component 20 may also be disposed inside the middle shell 60.

[0087] The image source component 20 can be arranged inside or outside the middle shell 60 to emit an imaging light beam to the window component 10 to form an image. However, arranging the image source component 20 outside the middle shell 60 helps to reduce the difficulty of assembling the image source component 20 and the middle shell 60, and can improve the production efficiency of the optical display 300.

[0088] Figure 7 for Figure 1 A front view schematic diagram of a metal bracket member in the optical display shown, Figure 8 for Figure 7 Schematic diagram of the cross section along the AA direction.

[0089] See also Figure 7 and Figure 8 As shown, the metal support member 50 is annular in structure, and the interior of the metal support member 50 is used for the imaging light beam to pass through, so as to ensure that the window member 10 reflects the imaging light beam from the image source member 20 and transmits the imaging light beam from the curved mirror 30.

[0090] In the embodiment of the present application, the first direction X is perpendicular to the second direction Y, and the first direction X is defined as the thickness direction of the window member 10 .

[0091] Fig. 9 for Figure 1 A schematic front view of a window member in the optical display shown, Fig.10 for Fig. 9 Schematic diagram of the cross section along the BB direction.

[0092] See also Figure 5 , Fig. 9 and Fig.10As shown, the window member 10 has a window area 11 and a shielding area 12. The shielding area 12 is annular and surrounds the window area 11. Along the first direction X, the projection of the window area 11 does not overlap with the metal bracket 50, and the projection of the shielding area 12 covers the area of ​​the metal bracket 50 opposite to the window member 10 in the first direction X. The window area 11 is used to transmit the imaging light beam inside the optical cavity A to the outside, and to reflect the imaging light beam to the curved mirror 30. The shielding area 12 is used to cover the area opposite to the metal bracket 50 and the window member 10 and the bonding structure between the metal bracket 50 and the window member 10, so as to prevent the user from seeing the metal bracket 50 and the bonding structure through the window member 10, thereby improving the appearance refinement of the optical display 300.

[0093] See also Figure 5 As shown, during the operation of the optical display 300, the image source element 20 emits an imaging light beam to the inner surface of the window area 11, the inner surface of the window area 11 reflects the imaging light beam to the surface of the curved mirror 30, the curved mirror 30 then reflects the imaging light beam to the inner surface of the window area 11, the imaging light beam from the curved mirror 30 passes through the inner surface of the window area 11 and is emitted from the outer surface of the window area 11 to the outside of the optical cavity A, and the imaging light beam finally enters the eye, and the eye can see the magnified virtual image.

[0094] When the optical display 300 is installed near the airbag, during the explosion of the airbag, the metal bracket 50 can resist the impact force brought by the airbag, and the airbag can be ensured to be in a corresponding position to ensure the safety of the user and meet the airbag test requirements.

[0095] In addition, due to the high strength of the metal bracket 50, the metal bracket 50 is not easy to deform, which can prevent the window part 10 from undergoing large deformation, so that the adhesion between the metal bracket 50 and the window part 10 is not easy to fail, thereby preventing the window part 10 from separating from the metal bracket 50 and causing secondary damage to the user.

[0096] Since the metal bracket 50 is connected to the window member 10 by bonding, the connection area between the window member 10 and the metal bracket 50 can be reduced as much as possible while ensuring the reliability of the connection between the window member 10 and the metal bracket 50, so that the shielding area 12 can be made narrower, and then the window area 11 can be made larger, which can increase the display area of ​​the optical display 300. In other words, the width of the portion of the metal bracket 50 opposite to the window member 10 in the first direction X can also be made narrower, so that the area of ​​the metal bracket 50 that needs to be covered by the shielding area 12 becomes smaller, and then the width of the shielding area 12 can be reduced.

[0097] In summary, by supporting the window member 10 with the metal bracket member 50 and bonding the metal bracket member 50 and the window member 10, the airbag explosion safety can be achieved on the one hand, and the shielding area 12 can be reduced on the other hand, thereby increasing the area of ​​the window area 11 and further increasing the display area of ​​the optical display 300.

[0098] It should be noted that the overall strength of the metal bracket 50 should meet the requirements of the airbag explosion test to ensure the safety of the airbag explosion and that the deformation of the metal bracket 50 is within a reasonable range when the airbag explodes.

[0099] In some implementations, the metal bracket 50 may be made of a high-strength material, such as an aluminum alloy. Of course, the metal bracket 50 may also be made of other materials. The high strength is defined as a strength greater than or equal to that of an aluminum alloy.

[0100] In other implementations, the metal bracket 50 may also be made of a low-strength material. In this case, by properly designing the structure of the metal bracket 50, the deformation of the metal bracket 50 is ensured to be within a reasonable range when resisting the impact force of the airbag. For example, the overall strength of the metal bracket 50 may be made to meet the requirements by increasing the thickness of the portion of the metal bracket 50 that is opposite to the window member 10 in the first direction X. Here, low strength is defined as less than the strength of aluminum alloy.

[0101] Continue to see Figures 6 to 8 As shown, the metal bracket 50 includes an annular main body 51 and an annular frame 52. The annular frame 52 is connected to the edge of the annular main body 51, and the annular main body 51 is bonded to the edge of the window member 10 and fixedly connected to the middle shell 60. The window member 10 is arranged inside the annular frame 52, and the projection of the window member 10 in the first direction X does not overlap with the projection of the annular frame 52.

[0102] Understandably, see Figure 7 and Figure 8 As shown, the annular main body portion 51 and the annular frame portion 52 form a groove for accommodating the window member 10, and a through hole penetrating the annular main body portion 51 is provided at the bottom of the groove, the axial direction of the through hole is parallel to the first direction X and is used for the imaging light beam to pass through, ensuring that the window area 11 reflects the imaging light beam to the curved mirror 30 and transmits the imaging light beam to the outside of the optical cavity A.

[0103] See also Figure 6 As shown, along the first direction X, the projection of the window area 11 does not overlap with the annular main body 51, and the projection of the shielding area 12 covers the annular main body 51 and does not overlap with the annular frame 52. On the one hand, the connection between the annular main body 51 and the window member 10 can be covered, and on the other hand, it can ensure that the window area 11 reflects or transmits the imaging light beam.

[0104] See also Figure 7 and Figure 8 As shown, the annular main body 51 is annular in structure and is bonded to the edge of the window member 10 , which can increase the bonding area between the window member 10 and the metal bracket member 50 , and helps to further improve the connection strength between the window member 10 and the metal bracket member 50 .

[0105] Since the bonding area between the annular main body 51 and the window member 10 is relatively large, when the width of the annular main body 51 is reduced, the bonding area between the annular main body 51 and the window member 10 can be ensured to be within a reasonable range, ensuring that the connection strength between the window member 10 and the metal bracket member 50 meets the requirements. Therefore, by bonding the annular main body 51 to the window member 10, it is also possible to provide a basis for reducing the area where the metal bracket member 50 and the window member 10 are opposite, thereby reducing the width of the shielding area 12.

[0106] Exemplarily, the annular frame portion 52 and the annular main body portion 51 are an integral structure. On the one hand, the annular frame portion 52 and the annular main body portion 51 can be manufactured in an integral molding manner to improve the manufacturing efficiency of the metal bracket 50. On the other hand, the connection strength between the annular frame portion 52 and the annular main body portion 51 can be improved, which helps to further improve the overall strength of the metal bracket 50. However, in some implementations, the annular main body portion 51 and the annular frame portion 52 can also be fixedly connected by welding, threaded connection, etc.

[0107] In some possible implementations, see Figure 6 As shown, along the second direction Y, the projection of the annular frame portion 52 covers the window member 10. In this way, the annular frame portion 52 can cover the side wall of the window member 10, thereby preventing the window member 10 from being damaged and improving the appearance refinement of the optical display 300.

[0108] It is understandable that the projection of the annular frame portion 52 in the second direction Y covers the window member 10, so that the metal bracket member 50 can also serve as an appearance member while supporting the window member 10. Specifically, the annular frame portion 52 serves as the appearance portion of the metal bracket member 50, and the annular main body portion 51 serves as the bearing portion of the metal bracket member 50 that supports the window member 10.

[0109] For example, Figure 6 As shown, the surface of the annular frame portion 52 facing away from the annular main body portion 51 along the first direction X is flush with the surface of the window member 10 facing away from the annular main body portion 51 along the first direction X, which can make the surface of the optical display 300 smoother and help improve the appearance refinement.

[0110] In some other implementations, the projection of the annular frame portion 52 in the second direction covers the window member 10, and the surface of the annular frame portion 52 along the first direction X facing away from the annular main body portion 51 may also be higher than the surface of the window member 10 along the first direction X facing away from the annular main body portion 51, thereby further improving the protective effect of the annular frame portion 52 on the window member 10.

[0111] Fig.11 A cross-sectional schematic diagram of a second optical display provided in an embodiment of the present application, Fig.12 for Fig.11 Enlarged schematic diagram of point N in the middle.

[0112] Fig.11 and Figure 5 The difference is that the projection of the annular frame portion 52 in the second direction Y does not overlap at least a portion of the window member 10, and the optical display 300 further includes a front shell 70. Specifically, see Fig.11 and Fig.12 As shown, at least parts of the window member 10 and the metal bracket member 50 are arranged inside the front shell 70, the projection of the front shell 70 in the first direction X does not overlap with the window member 10 and overlaps with the annular frame portion 52, and the projection of the front shell 70 in the second direction Y overlaps with the window member 10.

[0113] In this way, the front shell 70 can be used as an appearance part, and the front shell 70 can cover the side wall of the window part 10 to prevent the window part 10 from being damaged, and can improve the appearance refinement. In addition, the material of the front shell 70 can be plastic or plastic, which is easy to shape and can more easily meet the modeling requirements. In addition, when the front shell 70 is made of non-metallic materials, it is low in weight, which helps to reduce the weight of the optical display 300.

[0114] The front shell 70 is an annular structure, ensuring that the front shell 70 can surround at least part of the window member 10 and the metal bracket member 50, so as to prevent the side of the window member 10 and at least part of the metal bracket member 50 from being exposed. In addition, the projection of the front shell 70 in the first direction X does not overlap with the window member 10, which can prevent the front shell 70 from affecting the surface of the window member 10 facing away from the annular main body 51 along the first direction, which helps to further improve the appearance refinement of the optical display 300.

[0115] For example, Fig.12 As shown, the projection of the annular frame portion 52 in the second direction Y does not overlap with a portion of the window member 10. In other words, the projection of the annular frame portion 52 in the second direction Y overlaps with a portion of the window member 10. At this time, the projection of the front shell 70 in the second direction Y covers another portion of the window member 10. In other implementations, the projection of the annular frame portion 52 in the second direction Y may not overlap with the projection of the window member 10. At this time, the projection of the front shell 70 in the second direction Y covers the window member 10.

[0116] For example, Fig.12 As shown, the surface of the front shell 70 facing away from the annular main body 51 along the first direction X is flush with the surface of the window member 10 facing away from the annular main body 51 along the first direction X, which can make the surface of the optical display 300 smoother and help improve the exquisite appearance. In other implementations, the surface of the front shell 70 facing away from the annular main body 51 along the first direction X can also be higher than the surface of the window member 10 facing away from the annular main body 51 along the first direction X, which can further improve the protection effect of the front shell 70 on the window member 10.

[0117] In some possible implementations, such as Fig.12 As shown, the projection of the front shell 70 in the first direction X covers the annular frame portion 52, and the projection of the front shell 70 in the second direction Y covers the metal bracket 50. In this way, the metal bracket 50 can be covered to prevent the metal bracket 50 from leaking out, which can improve the appearance refinement of the optical display 300. At the same time, using the front shell 70 to cover the metal bracket 50 can expand the application range of the front shell 70 and reduce the number of parts of the optical display 300.

[0118] In some possible implementations, the front shell 70 can be fixedly connected to the metal bracket 50. During the assembly process of the optical display 300, the front shell 70 and the metal bracket 50 can be pre-assembled into a whole, which can reduce the number of assemblies of the optical display 300 and help improve the production efficiency of the optical display 300.

[0119] There is no specific limitation on how the front housing 70 is fixedly connected to the metal bracket 50. Fig.12 As shown, the front shell 70 is provided with a first hole 201 , the metal bracket 50 is provided with a second hole 202 , a fixing screw 203 passes through the second hole 202 and is inserted into the first hole 201 , and the fixing screw 203 is threadedly connected with the front shell 70 .

[0120] In some possible implementations, such as Figure 6 As shown, the window member 10 and the metal bracket member 50 form a receiving portion 91, and the receiving portion 91 is used to receive glue 92 for bonding the window member 10 and the metal bracket member 50. In this way, the window member 10 and the metal bracket member 50 can be firmly connected on the basis of reducing the width of the metal bracket member 50.

[0121] Specifically, the metal bracket member 50 is annular in structure, and thus the accommodating portion 91 is an annular groove, so that the bonding area between the metal bracket member 50 and the window member 10 is annular, thereby increasing the bonding area between the metal bracket member 50 and the window member 10 .

[0122] In some possible implementations, such as Figure 6 As shown, an annular protrusion 94 is provided at the bottom of the annular groove, and the annular protrusion 94 and the interior of the annular groove can form two glue overflow grooves separated by the annular protrusion 94. The excess glue 92 can be accommodated by the glue overflow grooves, thereby improving the appearance refinement of the optical display 300.

[0123] Fig.13 A cross-sectional schematic diagram of a third optical display provided in an embodiment of the present application, Fig.14 for Fig.13 Enlarged schematic diagram of point L in the middle.

[0124] In some other possible implementations, see Fig.13 and Fig.14 As shown, the optical display 300 may further include an adhesive member 93, through which the window member 10 is fixedly connected to the metal bracket member 50, and the projection of the shielding area 12 in the first direction X covers the adhesive member 93. In this way, on the basis of reducing the width of the metal bracket member 50, it can be ensured that the window member 10 and the metal bracket member 50 are firmly connected.

[0125] Specifically, the adhesive member 93 is an annular structure, and the adhesive member 93 is located between the annular main body 51 and the window member 10 and is respectively bonded to the adhesive member 93 to achieve bonding of the window member 10 and the metal bracket member 50 .

[0126] There is no limitation on the specific structure of the adhesive member 93. For example, the adhesive member 93 may be an adhesive-backed member.

[0127] In some possible implementations, one of the metal support member 50 and the middle shell 60 is provided with an annular groove portion 821, and the other is provided with an annular protrusion portion 822, and the annular protrusion portion 822 is inserted into the annular groove portion 821 and forms a labyrinth structure 82 for sealing the connection between the metal support member 50 and the middle shell 60 with the annular groove portion 821. In this way, the connection between the middle shell 60 and the metal support member 50 can also be sealed to prevent water, dust, etc. from entering the optical cavity A, thereby achieving dustproof and waterproof.

[0128] For example, Figure 6 As shown, the middle shell 60 is provided with an annular groove portion 821, and the metal bracket 50 is provided with an annular protrusion portion 822. The annular protrusion portion 822 is inserted into the inside of the annular groove portion 821, and the side wall of the annular protrusion portion 822 abuts against the groove side wall of the annular groove portion 821, which can form a labyrinth structure 82 at the connection between the sealed metal bracket 50 and the middle shell 60.

[0129] In some implementations, the annular groove portion 821 may also be disposed on the metal bracket 50 , and correspondingly, the annular protrusion portion 822 may be disposed on the middle shell 60 .

[0130] Fig.15 A schematic cross-sectional view of a fourth optical display provided in an embodiment of the present application, Fig.16 for Fig.15 Enlarged schematic diagram of point G in the middle.

[0131] For other possible implementations, see Fig.15 and Fig.16 As shown, the optical display 300 may further include a seal 81, which is disposed between the metal support member 50 and the middle shell 60 and abuts against the metal support member 50 and the middle shell 60 respectively. The seal 81 is used to seal the connection between the metal support member 50 and the middle shell 60 to prevent water, dust, etc. from entering the optical cavity A, thereby achieving dustproof and waterproof properties.

[0132] Specifically, the seal 81 is an annular structure, which is disposed between the annular body 51 and the middle shell 60 and abuts against the annular body 51 and the middle shell 60 respectively to seal the connection between the annular body 51 and the middle shell 60 .

[0133] There is no limitation on the specific structure of the sealing member 81. For example, the sealing member 81 may be a sealing rubber strip.

[0134] In some possible implementations, see Fig. 9 and Fig.10 As shown, the window member 10 includes a window element 13 and an annular shielding layer 14, the shielding layer 14 is disposed between the window element 13 and the metal bracket member 50, the shielding layer 14 is fixedly connected to the window element 13 and bonded to the metal bracket member 50, the shielding layer 14 is used to form a shielding area 12, and the shielding layer 14 can cover the area of ​​the window element 13 opposite to the metal bracket member 50 in the first direction X. In this way, the shielding layer 14 can divide the window member 10 into a window area 11 and a shielding area 12, and can cover the connection between the window member 10 and the metal bracket member 50 to prevent the user from seeing it.

[0135] Exemplarily, the material of the window element 13 may be glass. Of course, the material of the window element 13 may also be other materials.

[0136] Exemplarily, the shielding layer 14 may be an ink layer. Of course, the shielding layer 14 may also be made of other materials.

[0137] In some implementations, the image source device 20 may use liquid crystal display (LCD) imaging technology. In other implementations, the image source device 20 may also use digital light processing (DLP) technology, laser scanning projection, etc.

[0138] There is no limitation on the specific structure of the image source 20. In some implementations, the image source 20 may include an imager and a light source (not shown), the light source is used to output a light beam to the imager, and the imager is used to generate an imaging light beam containing image information according to the light beam.

[0139] The imager may be a liquid crystal on silicon (LCOS) display, an organic light-emitting diode (OLED) display, a liquid crystal display (LCD), a digital light processing (DLP) display or a micro-electro-mechanical systems (MEMS) display.
