[0005] Since the window body and the connector of the window member are an integrated structure, there is no gap at the connection between the window body and the connector, so there is no step difference on the front of the window member, which can improve the aesthetics of the optical display. In addition, by connecting the connector to the shell, the constraints of the connection between the window member and the shell can be reduced, and the reliability of the connection between the window member and the shell can be improved. Among them, the front of the window member refers to the surface of the window member facing away from the shell.

[0045] Figure 1 is a cross-sectional schematic diagram of an optical display in the related art, Figure 2 for Figure 1 The partially enlarged schematic diagram in the dashed box is shown in FIG. Figure 1 As shown, the optical display 51 includes a housing 52, a window unit 53, an image generating unit 54 and a curved mirror 55. The window unit 53 is connected to the housing 52 and encloses a cavity for accommodating the image generating unit 54 and the curved mirror 55. The image generating unit 54 is used to emit imaging light. The curved mirror 55 is used to reflect the imaging light from the window unit 53 to the window unit 53. The window unit 53 is used to reflect the imaging light from the image generating unit 54 to the curved mirror 55, and the window unit 53 is also used to transmit the imaging light reflected by the curved mirror 55 to the outside of the optical display 51.

[0046] However, if Figure 2 As shown, the window unit 53 is connected to the housing 52 by gluing, so that a gap for accommodating glue 56 is formed between the window unit 53 and the housing 52, so that a gap appears on the front of the optical display 51 (such as Figure 2 In addition, in order to meet the appearance requirements of the optical display 51, the gap between the housing 52 and the window unit 53 cannot be too large, so that the tolerance of the glue 56 is weak, resulting in a relatively small amount of glue 56, so that the firmness of the bonding between the housing 52 and the window unit 53 is low, and the reliability of the connection between the window unit 53 and the housing 52 is poor. In addition, the glue 56 is easy to overflow to the front of the optical display 51, further reducing the aesthetics of the optical display 51.

[0047] In view of this, the embodiment of the present application provides an optical display 100, a display device and a vehicle 200, wherein the window member 30 of the optical display 100 is formed by a window body 31 and a connector 32 of an integral structure, so that the front of the window member 30 has no step difference, and thus the front of the optical display 100 has no step difference, thereby improving the aesthetics of the optical display 100. In addition, the window member 30 is connected to the housing 40 through the connector 32, which can improve the reliability of the connection between the window member 30 and the housing 40.

[0048] The vehicle 200 provided in the embodiment of the present application may include but is not limited to known vehicles 200 such as cars, airplanes, ships, trains, etc. In addition, the vehicle 200 provided in the embodiment of the present application may also be a new vehicle 200 that will appear in the future.

[0050] Figure 3 A schematic diagram of the structure of a vehicle 2 provided in an embodiment of the present application.

[0051] The vehicle 200 provided in the embodiment of the present application includes a vehicle body and an optical display 100. The optical display 100 is installed on the vehicle body. The vehicle body includes a seat 300, a dashboard 400 and a headlight 500. The seat 300 includes a seat body 310 and a headrest 320. The headrest 320 is connected to the seat body 310.

[0052] The seat 300 may include a front row seat and a rear row seat, and the rear row seat is arranged on one side of the back of the front row seat, that is, the rear row seat is located behind the front row seat. In some implementations, the front row seat is generally arranged as a main driving seat and a co-pilot seat. In other implementations, both the front row seat and the rear row seat can be arranged as the seat 300 other than the main driving seat and the co-pilot seat.

[0053] The seat 300, the instrument panel 400, or the headlight 500 in the vehicle body may be installed with the optical display 100. Exemplarily, at least one of the seat 300 and the instrument panel 400 is installed with the optical display 100.

[0054] In some implementations, the seat 300 may be installed with an optical display 100. For example, by installing the optical display 100 on the front seat, the passengers sitting on the rear seat can see the picture displayed on the optical display 100. In other implementations, the optical display 100 may be installed on the instrument panel 400 so that the passengers sitting on the main driver's seat or the co-driver's seat can see the picture on the optical display 100. In other implementations, the optical display 100 may also be installed on both the instrument panel 400 and the seat 300.

[0055] In some possible implementations, when the optical display 100 is installed on the seat 300, at least one of the seat body 310 and the headrest 320 may be installed with the optical display 100. In some implementations, the optical display 100 may be installed on the seat body 310. In other implementations, the optical display 100 may also be installed on the headrest 320. In still other implementations, the optical display 100 may also be installed on both the seat body 310 and the headrest 320.

[0056] It should be noted that the optical display 100 provided in the embodiment of the present application can be applied to other devices in addition to being applied to the vehicle 200. In some implementations, the optical display 100 can also be applied to display devices such as head-up display (HUD), projector, television, near eye display (NED) device, etc.

[0057] 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.

[0058] Among them, the types of HUD include but are not limited to windshield (W)-HUD, augmented reality head-up display (AR-HUD), etc.

[0059] In some other implementations, the optical display 100 may also be used in medical equipment, office entertainment equipment, industrial control equipment, and the like, without specific limitation herein.

[0060] The implementation method of the optical display 100 provided in the embodiment of the present application is described below.

[0061] Figure 4 A cross-sectional schematic diagram of a first optical display provided in an embodiment of the present application, Figure 5 for Figure 4 A partial enlarged schematic diagram of point b in the middle.

[0062] See also Figure 4 As shown, the optical display 100 of the embodiment of the present application includes a housing 40, a window member 30, an image generating unit 10 and an image magnifying unit 20. The housing 40 is used to fix the optical display 100, and is also used to carry the window member 30, the image generating unit 10 and the image magnifying unit 20. The image generating unit 10 is used to emit imaging light L to the window member 30, and the imaging light L is used to generate an image. The window member 30 is used to reflect the imaging light L from the image generating unit 10 to the image magnifying unit 20, and is also used to project the imaging light L from the image magnifying unit 20 to the outside of the optical display 100. The image magnifying unit 20 is used to reflect the imaging light L from the window member 30 to the window member 30.

[0063] See also Figure 4 As shown, during the operation of the optical display 100, the image generating unit 10 emits imaging light L (such as Figure 4 The inner surface 301 of the window member 30 reflects the imaging light L to the surface of the image magnifying unit 20, and the image magnifying unit 20 reflects the imaging light L to the inner surface 301 of the window member 30. The imaging light L reflected by the image magnifying unit 20 passes through the inner surface 301 of the window member 30 and is emitted from the outer surface 302 of the window member 30 to the outside of the optical display 100. After the imaging light L enters the outside of the optical display 100, it enters the eye 50, and the eye 50 can see the magnified virtual image.

[0064] The virtual image can be viewed by the eye 50 without being received by the light curtain. Figure 4 As shown, the image generating unit 10 emits imaging light L with a certain divergence angle, which enters the eye 50 after being reflected by the window member 30 and the image magnifying unit 20. The brain will trace the light in reverse based on the experience that "light travels in a straight line", and considers the intersection of the imaging light L with the reverse extension as the object point, that is, the virtual image point. Among them, the position of the eye 50 can be called the eyebox position. The imaging light L includes imaging light L1 and imaging light L2, and the two imaging lights L define the divergence angle of the light emitted by the image generating unit 10.

[0065] In some implementations, the imaging light transmitted by the window member 30 to the outside of the optical display 100 may also be emitted onto a light curtain (not shown in the figure) located outside the optical display 100. 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.

[0066] In some implementations, the image generation unit 10 may use liquid crystal display (LCD) imaging technology. In other implementations, the image generation unit 10 may also use digital light processing (DLP) technology, laser scanning projection, etc.

[0067] There is no limitation on the specific structure of the image generating unit 10. In some implementations, the image generating unit 10 may include an imager and a light source (not shown in the figure), the light source is used to output a light beam to the imager, and the imager is used to generate imaging light containing image information according to the light beam.

[0068] 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.

[0069] The specific structure of the image magnifying unit 20 is not limited here. For example, Figure 4 As shown, the image magnifying unit 20 may include a curved mirror 21 , and a concave surface of the curved mirror 21 is used to reflect the image light from the window member 30 to the window member 30 .

[0070] The curved mirror 21 may be a free-form surface reflector, a spherical reflector, an aspherical reflector or other reflectors, and no specific limitation is given here.

[0071] In some implementations, the housing 40 may be an integrally formed housing (eg Figure 4 As shown), in other words, the multiple parts constituting the housing 40 are an integrated structure. In other implementations, the housing 40 may also be composed of at least two parts, in other words, the housing 40 is a split structure.

[0072] In some possible implementations, such as Figure 4As shown, the housing 40 and the window member 30 enclose a cavity 60, and the image generating unit 10 and the image magnifying unit 20 are disposed inside the cavity 60. In this way, the number of parts of the optical display 100 can be reduced, the number of assembly times of the optical display 100 can be reduced, and the production efficiency of the optical display 100 can be improved. In addition, dust can be reduced from entering the cavity 60, avoiding the image generating unit 10 and the image magnifying unit 20 from being affected.

[0073] In the embodiments of the present application, Figure 5 As shown, the window member 30 includes a window body 31 and a connecting body 32 of an integrated structure. The connecting body 32 is fixedly connected to the housing 40 , and the window body 31 is used to transmit the imaging light in the optical display 100 to the outside of the optical display 100 .

[0074] Wherein, at least a portion of the connector 32 is disposed between the window body 31 and the housing 40. In some implementations, such as Figure 4 As shown, the connector 32 is disposed between the window body 31 and the housing 40. In other implementations, a portion of the connector 32 may be disposed between the window body 31 and the housing 40, and another portion may be disposed outside the gap between the window body 31 and the housing 40.

[0075] like Figure 4 As shown, during the operation of the optical display 100, the image generating unit 10 emits imaging light L to the inner surface 301 of the window body 31, the inner surface 301 of the window body 31 reflects the imaging light L to the surface of the image magnifying unit 20, the image magnifying unit 20 then reflects the imaging light L to the inner surface 301 of the window body 31, the imaging light L reflected by the image magnifying unit 20 passes through the inner surface 301 of the window body 31 and is emitted from the outer surface 302 of the window body 31 to the outside of the optical display 100. After the imaging light L enters the outside of the optical display 100, it enters the eye 50, and the eye 50 can see the magnified virtual image.

[0076] The window body 31 can be integrally formed with the connector 32 by two-color integral injection molding, so that the window body 31 and the connector 32 are an integral structure. Of course, the method of integrally forming the window body 31 and the connector 32 is not limited to two-color integral injection molding.

[0077] In the embodiment of the present application, since the window body 31 and the connecting body 32 of the window member 30 are in an integrated structure, there is no gap at the connection between the window body 31 and the connecting body 32, so that there is no step on the front of the window member 30, thereby improving the aesthetics of the optical display 100. In addition, by connecting the connecting body 32 to the housing 40, the constraints of the connection between the window member 30 and the housing 40 can be reduced, and the reliability of the connection between the window member 30 and the housing 40 can be improved.

[0078] There is no limitation on the specific material of the window body 31. For example, the window body 31 may be glass that can reflect and transmit imaging light.

[0079] There is no limitation on the specific material of the connector 32. For example, the connector 32 may be made of plastic.

[0080] like Figure 5 As shown, the connector 32 is arranged on the side of the window body 31 facing the outer shell 40, so that the connection between the connector 32 and the window body 31 is located on the side of the window body 31 facing the outer shell 40, so that there is no joint seam on the surface of the window piece 30 facing away from the outer shell 40, so that the front of the window piece 30 is a full screen, which can further improve the aesthetics of the optical display 100.

[0081] It can be understood that along the thickness direction of the window body 31 (eg Figure 5 The direction perpendicular to the X direction (such as Figure 5 The projection of the viewing body 31 does not overlap with the projection of the connecting body 32. Figure 5 In the X direction), the top surface of the connecting body 32 is flush with the bottom surface of the window body 31, and the top surface of the connecting body 32 is arranged between the top surface of the window body 31 and the bottom surface of the connecting body 32.

[0082] like Figure 5 As shown, along the thickness direction of the window body 31 (such as Figure 5 The projection of the window body 31 partially overlaps with the projection of the connector 32 , thereby ensuring that the window body 31 can transmit the imaging light to the outside of the optical display 100 .

[0083] Combination Figure 4 and Figure 5 It can be seen that the connector 32 includes a main body 321 of an annular structure, which is disposed on a side of the window body 31 facing the housing 40 and located at an edge of the window body 31 . The connector 32 is connected to the window body 31 via the main body 321 .

[0084] Combination Figure 4 and Figure 5 It can be known that the connector 32 may be an annular structure, which is disposed at the edge of the window body 31 to ensure that the connector 32 does not affect the projection and reflection of imaging light by the window body 31. In some implementations, the connector 32 may not be an annular structure, in which case the connector 32 may also include a plurality of connecting portions (not shown in the figure), which are disposed at intervals along the circumference of the window body 31.

[0085] In some possible implementations, in order to achieve a fixed connection between the connector 32 and the housing 40, one of the connector 32 and the housing 40 is provided with a second receiving portion 41, and the other includes a fixing portion 322 for inserting into the second receiving portion 41, and the connector 32 is fixedly connected to the housing 40 via the fixing portion 322. In some implementations, such as Figure 5 As shown, the fixing portion 322 may be disposed on the connecting body 32 and the second receiving portion 41 may be disposed on the housing 40. In other implementations, the fixing portion 322 may also be disposed on the housing 40 and the second receiving portion 41 may also be disposed on the connecting body 32.

[0086] The fixing portion 322 can be fixedly connected to the connecting body 32 or the housing 40 by bonding, threading, etc., so as to achieve a fixed connection between the connecting body 32 and the housing 40. Figure 5 As shown, the connector 32 may be provided with a fixing portion 322, and the housing 40 may be provided with a second receiving portion 41. The fixing portion 322 is provided on one side of the housing 40 of the main body 321 and is integrally structured with the main body 321, and the fixing portion 322 is provided inside the second receiving portion 41 and bonded to the inner wall of the second receiving portion 41.

[0087] In the embodiment of the present application, the fixing portion 322 can be fixedly connected to the housing 40 by bonding, which can also reduce the difficulty and cost of connecting the fixing portion 322 to the housing 40. In addition, the second receiving portion 41 has a strong glue tolerance, which can increase the amount of glue dispensed for bonding the fixing portion 322 to the inner wall of the second receiving portion 41, and can improve the reliability of the internal connection between the fixing portion 322 and the second receiving portion 41.

[0088] It can be understood that since the second accommodating portion 41 is arranged in the outer shell 40, the volume of the second accommodating portion 41 can be enlarged, so that it can accommodate more glue 70, and then the bonding area between the second accommodating portion 41 and the fixing portion 322 can be increased, thereby achieving the purpose of improving the reliability of the connection between the connecting body 32 and the outer shell 40.

[0089] like Figure 5 As shown, the inner wall of the second receiving portion 41 can be bonded to the fixing portion 322 by glue 70 . Of course, the fixing portion 322 can also be bonded to the inner wall of the second receiving portion 41 by using other materials with bonding properties.

[0090] Combination Figure 4 and Figure 5 It can be known that the fixing portion 322 can be an annular structure. In some implementations, the fixing portion 322 can also include a plurality of fixing segments (not shown in the figure) arranged at intervals along the circumference of the window body 31.

[0091] like Figure 5As shown, the cross section of the fixing portion 322 may be rectangular. In some implementations, the cross section of the fixing portion 322 may also be triangular, semicircular, etc. The cross section of the fixing portion 322 is perpendicular to the window body 31 and parallel to the thickness direction of the window body 31.

[0092] like Figure 5 As shown, the second receiving portion 41 may be a receiving groove disposed on the housing 40, and the notch of the receiving groove faces the window member 30. In addition, the fixing portion 322 is an annular structure, and the receiving groove may be an annular groove to receive the fixing portion 322.

[0093] like Figure 5 As shown, the fixing portion 322 does not contact the bottom wall of the second receiving portion 41 facing the window member 30, and there is a gap between the fixing portion 322 and the bottom wall of the second receiving portion 41 facing the window member 30. In this way, the bonding area between the fixing portion 322 and the inner wall of the second receiving portion 41 can be increased, which helps to further improve the firmness of the connection between the fixing portion 322 and the second receiving portion 41. Figure 5 X direction) vertical.

[0094] like Figure 5 As shown, along the thickness direction of the window body 31 (such as Figure 5 The direction perpendicular to the X direction (such as Figure 5 In the middle Z direction), the size of the second receiving portion 41 is larger than that of the fixing portion 322, which can ensure that the fixing portion 322 is inserted into the second receiving portion 41 and improve the glue tolerance capacity of the second receiving portion 41, thereby achieving the purpose of increasing the glue dispensing amount.

[0095] In some possible implementations, such as Figure 5 As shown, the connector 32 may further include a shielding portion 323, and the shielding portion 323 is used to shield the fixing portion 322 and the second receiving portion 41. In this way, the aesthetics of the optical display 100 can be improved by shielding the fixing portion 322 and the second receiving portion 41 with the shielding portion 323. In addition, foreign matter such as dust can be prevented from entering the interior of the optical display 100, further improving the dustproof performance.

[0096] like Figure 5 As shown, the shielding portion 323 is connected to the main body 321 and forms an integral structure with the main body 321. In some implementations, the shielding portion 323 may also be connected to the fixing portion 322.

[0097] Combination Figure 4It can be seen that the shielding portion 323 is a hollow structure, and one end of the shielding portion 323 is connected to the main body portion 321, so that the fixing portion 322 and the second accommodating portion 41 are arranged inside the shielding portion 323, so that the shielding portion 323 can shield the fixing portion 322 and the second accommodating portion 41, thereby preventing the fixing portion 322 and the second accommodating portion 41 from being exposed.

[0098] In some possible implementations, such as Figure 5 As shown, the housing 40 may also be provided with an escape portion 42, and the escape portion 42 is used to escape the shielding portion 323. In this way, it is possible to avoid the shielding portion 323 from interfering with the housing 40. In addition, the escape portion 42 may be used to accommodate the shielding portion 323, which may improve the compactness of the optical display 100 and contribute to miniaturization of the optical display 100.

[0099] The specific structure of the avoidance portion 42 is not shown here. In some implementations, the avoidance portion 42 can be a avoidance groove. In other implementations, the avoidance portion 42 can also be a avoidance notch (such as Figure 5 shown).

[0100] In the above content, the connecting body 32 is arranged on the side of the window body 31 facing the housing 40. However, a part of the connecting body 32 can also be arranged on the side of the window body 31 facing the housing 40, and another part can also be arranged in parallel with the window body 31, such as Figure 6 shown.

[0101] Figure 6 A cross-sectional schematic diagram of a second optical display provided in an embodiment of the present application, Figure 7 for Figure 6 A local enlarged schematic diagram of point c in the middle.

[0102] Figure 6 and Figure 4 The difference is that the structure of the connector 32 is different. Specifically, Figure 7 As shown, the connecting body 32 is provided with a first accommodating portion 324, the window body 31 is arranged inside the first accommodating portion 324, and the surface of the window body 31 facing away from the housing 40 is flush with the surface of the connecting body 32 facing away from the housing 40. In this way, on the basis of achieving no step difference on the front of the window member 30, the connecting body 32 can also surround the side wall of the window body 31 to protect the window body 31, reduce the possibility of the window body 31 being scratched and damaged, and thus extend the service life of the window body 31. In addition, the possibility of users being scratched or cut by the edge of the window body 31 can also be reduced, thereby improving the safety and reliability of the optical display 100.

[0103] like Figure 7As shown, the connecting body 32 includes a main body 321, a fixing part 322 and a shielding part 323. The fixing part 322 is connected to a first end of the main body 321, and the shielding part 323 is connected to a second end of the fixing part 322. The main body 321 is connected to the window body 31, and the main body 321 is provided with a first accommodating part 324. A part of the main body 321 is arranged on a side of the window body 31 facing the housing 40, and another part is arranged in parallel with the window body 31 in a direction perpendicular to the thickness direction of the window body 31. In this way, the connection area between the window body 31 and the connecting body 32 can be further increased, and the reliability of the connection between the window body 31 and the connecting body 32 can be further improved.

[0104] like Figure 7 As shown, the main body 321 includes a first main body 3211 and a second main body 3212 of an integral structure. The first main body 3211 is disposed on the side of the window body 31 facing the housing 40 and connected to the window body 31. The first end and the second end of the first main body 3211 are connected to the fixing portion 322 and the shielding portion 323 respectively. Figure 7 The direction perpendicular to the X direction (such as Figure 7 The second body 3212 is arranged in parallel with the window body 31 and connected to the window body 31. Along the thickness direction of the window body 31, the surface of the second body 3212 facing away from the housing 40 is flush with the surface of the window body 31. The second body 3212 and the first body 3211 form a first accommodating portion 324 for accommodating the window body 31.

[0105] Combination Figure 6 and Figure 7 It can be seen that the first body 3211 can be a ring-shaped plate structure, which can ensure that the window body 31 reflects and transmits the imaging light.

[0106] Combination Figure 6 and Figure 7 It can be seen that the second body 3212 is an annular structure surrounding the window body 31, which can not only increase the connection area between the connector 32 and the window body 31, but also surround the side wall of the window body 31 to protect the window body 31 and the user.

[0107] like Figure 7 As shown, the cross section of the second body 3212 may be a right-angled trapezoid. In some implementations, the cross section of the second body 3212 may also be other shapes, such as a rectangle. The cross section of the second body 3212 is perpendicular to the window body 31 and parallel to the thickness direction of the window body 31 (e.g., Figure 7 X direction).
