Therefore, the features defined with "first" and "second" can explicitly or implicitly include at least one of the features.

[0066] The present application provides an optical display assembly and a smart head-mounted device, which are described in detail below. It should be noted that the description order of the following embodiments is not limited as the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment is focused on, and the parts not described in detail in a certain embodiment can be referred to the related description of other embodiments.

[0067] Please refer to Figure 1 The embodiment of the present application provides an optical display assembly 100. Here, in order to describe the positional relationship between the components, in the embodiments of the present application, a first direction X, a second direction Y and a third direction Z are defined. In the orientation state shown in the figure, the first direction X, the second direction Y and the third direction Z are perpendicular to each other, but it can be understood that in other embodiments, the positional relationship between the first direction X, the second direction Y and the third direction Z is not limited to being perpendicular to each other, and the present embodiment does not limit it. Figure 1 The embodiment of the present application provides an optical display assembly 100. Here, in order to describe the positional relationship between the components, in the embodiments of the present application, a first direction X, a second direction Y and a third direction Z are defined. In the orientation state shown in the figure, the first direction X, the second direction Y and the third direction Z are perpendicular to each other, but it can be understood that in other embodiments, the positional relationship between the first direction X, the second direction Y and the third direction Z is not limited to being perpendicular to each other, and the present embodiment does not limit it.

[0068] Generally, the optical display assembly 100 comprises a containing shell 110, in which a containing space is arranged for carrying and accommodating other components of the optical display assembly 100, and the containing shell 110 can form protection for the components arranged in the containing space. Of course, it can be understood that the embodiment is not limited to all components of the optical display assembly 100 being arranged in the containing space, and part of the components of the optical display assembly 100 can also be arranged outside the containing shell 110 or extended from the containing space to outside the containing shell 110, etc. At the same time, in other embodiments, the optical display assembly 100 can also not be provided with the containing shell 110, which is not limited by the embodiment.

[0069] Here, the containing shell 110 exemplarily comprises a first shell 111 and a second shell 112 arranged opposite along the first direction X, and the first shell 111 and the second shell 112 are covered with each other to form the aforementioned containing space. Of course, in other embodiments, the first shell 111 and the second shell 112 are not limited to being arranged opposite along the first direction X.

[0070] Here, the first shell 111 and the second shell 112 can be connected with each other by bolting or other detachable ways, so as to facilitate the installation, disassembly and replacement of the components in the containing shell 110, etc. However, it can be understood that in other embodiments, the containing shell 110 can also be an undetachable whole, for example, the first shell 111 and the second shell 112 are connected by welding, bonding or other ways which are not easy to disassemble, or the entire containing shell 110 can be obtained by integral molding, etc., which is not limited by the embodiment.

[0071] Please refer to Figure 2 , Figure 2 Exemplarily, a schematic view of the first shell 111 and the second shell 112 being separated is shown to show the components and structures in the containing space. Here, the main components of the optical display assembly 100 are shown, which comprise a camera 120, an optical engine module 130 and a control device 140, which will be described respectively below.

[0072] Here, the camera 120 is used for image acquisition to obtain relevant image information. Exemplarily, when the optical display assembly 100 of the embodiment is used to realize the AR (Augmented Reality) effect, the camera 120 is used to shoot the real scene image of the space where the user is located when using. Here, the camera 120 can be an RGB camera, a depth camera, etc., but the embodiment is not limited thereto. Moreover, the camera 120 is connected to the control device 140, so as to transmit the relevant image information acquired to the control device 140.

[0073] For example, please continue to refer to Figure 2 , the camera 120 includes a lens 121, which has an optical axis A. In this embodiment, the lens 121 is arranged along the first direction X, which is the axial direction of the optical axis A. Here, the length of the camera 120 in the first direction X is longer than the length of the optical engine module 130.

[0074] The optical engine module 130 is arranged on one side of the camera 120. For example, please refer to Figure 2 , the optical engine module 130 can be located on the side of the camera 120 in the third direction Z, which is perpendicular to the first direction X and the second direction Y. Here, the optical engine module 130 is connected to the control device 140 for outputting optical images and realizing the effects of VR (Virtual Reality), AR (Augmented Reality), MR (Mixed Reality), etc. For example, taking the AR technology as an example, the optical engine module 130 can be arranged based on curved surface reflection, waveguide, etc. The corresponding technical principles and basic structures are well known to those skilled in the art, and will not be described in detail in this embodiment.

[0075] For example, please refer to Figure 3 , Figure 3 The structure of the optical engine module 130 and its position in the accommodating shell 110 are shown in this embodiment. Here, the optical engine module 130 includes an image source 131, a lens group 132, and an imaging unit 133, which can be arranged in sequence along the second direction Y.

[0076] Here, the image source 131 can be an OLED (Organic Light-Emitting Diode), an LCD (Liquid Crystal Display), a QLED (Quantum Dot Light-Emitting Diode), etc., which is not limited in this embodiment.

[0077] The lens group 132 can be a convex mirror module or a prism module, etc., which is used to adjust the light path of the image source 131, so as to project the light emitted by the image source 131 to the imaging unit 133. In this embodiment, the lens group 132 specifically adopts a convex mirror module, which has a relatively thin thickness, which is helpful to realize miniaturization design.

[0078] The imaging unit 133 can be a waveguide sheet group or the like, which is configured to receive the light emitted by the image source 131 and present a corresponding optical image to the user. Here, the imaging unit 133 extends along the second direction Y, and correspondingly, a second opening 115 is provided on the accommodation shell 110 at a position corresponding to the imaging unit 133, and the second opening 115 is configured to allow the imaging unit 133 to extend out of the accommodation space formed in the accommodation shell 110.

[0079] Here, please refer to Figure 5 , in order to protect the part of the imaging unit 133 extending out of the accommodation space, a protective piece 190 can also be provided, which is arranged on the accommodation shell 110 and covers the part of the imaging unit 133 extending out of the accommodation space. Here, the protective piece can be connected to the accommodation shell 110 in a clamping, pasting, bolt connection or the like manner, or can be integrally formed with the accommodation shell 110, and the present embodiment does not limit it. At the same time, in order to prevent the protective piece from blocking the user's line of sight and affecting the user's observation of the optical image presented by the imaging unit 133, the protective piece also has a transparent part, which is at least located at a display side 191 of the imaging unit 133, which is the side for the user to observe during use, Figure 5 The direction E of the user's line of sight when observing the imaging unit 133 is exemplarily shown in FIG. 1B, and it can be seen that during use, the user observes the imaging unit 133 from the display side 191. Exemplarily, the part of the protective piece at the display side 191 of the imaging unit 133 is made of a transparent material so as not to affect the user's field of view, for example, the transparent material can be glass, transparent plastic or the like. Exemplarily, the protective piece can also be made of a transparent material as a whole. In addition, in some embodiments, a non-display side of the imaging unit 133 can also be provided with a light shielding piece or coated with a light shielding material, so as to avoid the influence of strong sunlight on the imaging of the imaging unit 133.

[0080] Here, please refer to Figure 3 , after adjustment by the lens group 132, the overall direction B of the light emitted by the image source 131 and projected to the imaging unit 133 is defined as the light emission direction, and in the present embodiment, the second direction Y is the light emission direction. Please refer to Figure 4 , Figure 4 which shows a side view of the optical display assembly 100, and in the state shown in Figure 4 , the light emission direction (i.e. the second direction Y) is specifically a downward direction. Here, the first direction X and the second direction Y are perpendicular to each other, and of course, in other embodiments, the included angle between the first direction X and the second direction Y can also be other angles, as long as the first direction X and the second direction Y are at an angle, i.e. they are not in the same direction.

[0081] Please refer toFigure 2 The control device 140 is connected to the camera 120 and the light machine module 130 for signal conversion and the like. For example, the camera 120 and the light machine module 130 can be connected to the control device 140 through a flexible printed circuit (FPC) data line. Of course, in other embodiments, the camera 120 and the light machine module 130 can be connected to the control device 140 through other data lines or in a wireless manner, and the present embodiment does not limit this.

[0082] For example, the control device 140 can include a data conversion module. Here, the data conversion module includes a first control circuit board 141 and a second control circuit board 142 connected to each other. The first control circuit board 141 is mainly used to convert electrical signals into a format recognizable by the light machine module 130. Here, please refer to Figure 7 The second control circuit board 142 is provided with a connection interface 1421, i.e., the second control circuit board 142 is mainly used to realize electrical connection with external structures. The connection interface 1421 can be a Type-C interface, a USB interface, or other interfaces, and the present embodiment does not limit this. Correspondingly, the accommodation shell 110 is provided with a first opening 114 on the side close to the second control circuit board, and the first opening 114 corresponds to the position of the connection interface 1421, so as to expose the connection interface 1421 and make the connection interface 1421 convenient to connect with devices outside the accommodation shell 110. In addition, please refer to Figure 3 The second control circuit board 142 is also provided with an indicator light 1422. Please refer to Figure 8 The accommodation shell 110 is provided with a window on the side opposite to the first direction X and corresponding to the indicator light 1422. The window is used to expose the indicator light 1422 to the outside of the accommodation shell 110, so that the user can observe the indicator light 1422. Here, the indicator light 1422 is used to present the working state of the optical display assembly 100. For example, when the optical display assembly 100 is in a working state, the display light 1422 is always on; when the optical display assembly 100 is in a shutdown state, the display light 1422 is off. For another example, the optical display assembly 100 has different working modes, and in different working modes, the display light 1422 presents different colors and / or display modes, including but not limited to always on, always off, flashing at a preset frequency, and the like.

[0083] Of course, in other embodiments, the data conversion module can be different from the above-mentioned embodiments. For example, the data conversion module can not be provided with the second control circuit board 142; the first control circuit board 141 can also have a connection interface; the second control circuit board 142 can also have a signal conversion function; the indicator light can be provided on the first control circuit board 141, and the like.

[0084] In addition, the control device 140 can be further provided with other various components. For example, the first control circuit board 141 and / or the second control circuit board 142 can be further provided with sensors such as a gyroscope and an accelerometer. For another example, the first control circuit board 141 and / or the second control circuit board 142 can be further provided with a processor to form a data processing module, which has a signal processing function and further has a function of processing signals according to a preset program or according to an instruction of a user. Of course, the types of the various components are not limited to the above examples, and a person skilled in the art can set and adjust according to actual needs. Here, the various components can be directly installed on the first control circuit board 141 and / or the second control circuit board 142 or other components of the control device 140, or can be connected to the first control circuit board 141 and / or the second control circuit board 142 or other components of the control device 140 through wiring or other means.

[0085] Here, the optical display assembly 100 has a receiving area 150, at least a part of the control device 140 is accommodated in the receiving area 150, which can be an internal space of the accommodating shell 110 or other space close to the camera device 120 and the light engine module 130, so as to accommodate at least part of the control device 140 and facilitate the connection between the control device 140 and the camera device 120 and the light engine module 130.

[0086] Here, please refer to Figure 3 , in Figure 3 , the first direction X is a direction from inside the paper to outside the paper, the lens 121 of the camera device 120 protrudes from the light engine module 130 along the first direction X, and thus a first receiving area 151 is formed on the side of the lens 121 close to the light engine module 130, and part or all of the receiving area 150 forms the first receiving area 151. Here, please refer to Figure 3 and Figure 5 , the light engine module 130 is arranged on one side of the lens 121 along the third direction Z, so the first receiving area 151 is located on one side of the lens 121 in the third direction Z.

[0087] Specifically, in the present embodiment, please refer to Figure 2The accommodating shell 110 is provided with a window portion 113 along the first direction X, which corresponds to the position of the lens 121. Here, the outer wall of the accommodating shell 110 extends along the outer edge of the window portion 113 in the first direction X, thereby shielding the lens 121 from the outside in the circumferential direction to protect the lens 121. In other embodiments, the outer wall of the accommodating shell 110 can not form circumferential protection for the outwardly convex lens 121, i.e., the lens 121 can protrude outwardly from the accommodating shell 110 through the window portion 113, which is not limited in the present embodiment.

[0088] Please refer to Figure 5 , Figure 5 It is shown that Figure 3 The lens 121 protrudes from the optical engine module 130 in the first direction X, and the inner wall of the accommodating shell 110 on the side close to the window portion 113 has a first gap in the first direction X with the optical engine module 130, which is configured as the aforementioned first accommodating area 151. The first control circuit board 141 of the control device 140 is arranged in the first accommodating area 151, which effectively utilizes the space formed due to the protrusion of the lens 121, thereby achieving a compact structure design and also not blocking the camera device 120 and the optical engine module 130. Moreover, the first control circuit board 141 is located on the side of the optical engine module 130 close to the lens 121, and in actual use, the optical engine module 130 is located on the side away from the user's eye, which does not affect the exit pupil distance between the optical engine module 130 and the eye, and helps the optical engine module 130 to achieve good imaging effect. Of course, in other embodiments, the first accommodating area 151 can also be used to accommodate other parts of the control device 140, such as being used to accommodate a second control circuit board 142 of the control device 140 or simultaneously accommodating the first control circuit board 141 and the second control circuit board 142, etc., which is not limited in the present embodiment.

[0089] It can be understood that in the present embodiment, the first accommodating area 151 is a substantially closed space enclosed by the accommodating shell 110, the camera device 120 and the optical engine module 130, and at least part of the control device 140 is arranged in the first accommodating area 151 and is not easily contacted and affected by the outside. However, the present embodiment does not specifically limit whether the first accommodating area 151 is enclosed to form a closed space by the accommodating shell 110 or other structures, and in other embodiments, for example, in embodiments without the accommodating shell 110, the first accommodating area 151 is the area located on the side of the lens 121 in the third direction Z and on the side of the optical engine module 130 in the first direction X. Here, the first accommodating area 151 can be a closed area or an open area, which is not limited in the present embodiment.

[0090] And it can be understood that the lens 121 of the camera 120 is generally convex along the first direction X, thus forming the aforementioned first accommodation area 151, but in other embodiments, other components of the camera 120 can be convex in a certain direction relative to the optical engine module 130, and further form the first accommodation area 151, which is not specifically limited in the present embodiment.

[0091] Meanwhile, please refer to Figure 6 In the present embodiment, the aforementioned accommodation area 150 includes not only the first accommodation area 151, but also a second accommodation area 152. The optical engine module 130 is convex along the second direction Y relative to the camera 120, and further forms the second accommodation area 152 on the side of the optical engine module 130 close to the camera 120. Here, the optical engine module 130 is disposed on one side of the camera 120 along the third direction Z, so the second accommodation area 152 is located on the side opposite to the camera 120 along the third direction Z.

[0092] Specifically, please refer to Figure 3 The optical engine module 130 includes a convex portion 134, which is convex along the second direction Y relative to the camera 120. Here, the convex portion 134 includes part of the lens group 132 and the imaging unit 133, but it can be understood that in other embodiments, the formation of the convex portion 134 is not limited to this, for example, the convex portion 134 can be entirely composed of the imaging unit 133, or the convex portion 134 includes part of the image source 131, the lens group 132 and the imaging unit 133. That is, the present embodiment does not limit the specific composition of the convex portion 134 of the optical engine module 130 which is convex along the second direction Y relative to the camera 120.

[0093] Here, in the second direction Y, the convex portion 134 has a second gap between the side close to the camera 120 and the inner wall of the accommodation shell 110, and the second gap is configured as the aforementioned second accommodation area 152. The second control circuit board 142 of the control device 140 is disposed in the second accommodation area 152, which effectively utilizes the space formed due to the convexity of the optical engine module 130, and further realizes a compact structure design, while also not causing occlusion to the camera 120 and the optical engine module 130. Of course, in other embodiments, other parts of the control device 140 can be disposed in the second accommodation area 152, for example, the first control circuit board 141 is disposed in the second accommodation area 152; or both the first control circuit board 141 and the second control circuit board 142 are disposed in the second accommodation area 152, which is not limited in the present embodiment.

[0094] It can be understood that, in the embodiment, the second accommodation area 152 is a substantially closed space enclosed by the contained shell 110, the camera 120 and the light machine module 130, and the at least partial control device 140 is arranged in the second accommodation area 152 and is not easily contacted and affected by the outside. However, the embodiment does not specifically limit whether the second accommodation area 152 is enclosed to form a closed space by the contained shell 110 or other structures. In other embodiments, for example, in an embodiment without the contained shell 110, the second accommodation area 152 is an area located on the side opposite to the third direction Z of the protruding part 134 and on the side of the camera 120 in the second direction. Here, the second accommodation area 152 can be a closed area or an open area, and the embodiment does not limit it.

[0095] It can be seen that, in the embodiment of the application, the space formed by the relatively protruding part between the camera 120 and the light machine module 130 is effectively utilized, and the space is used as an accommodation space for accommodating the at least partial control device 140. The arrangement realizes a compact structure design and does not cause occlusion to the optical path of the camera 120 and the light machine module 130. The optical display assembly 100 has the advantages of miniaturization and easy carrying while realizing the corresponding AR function or other functions.

[0096] In the above embodiment, the first accommodation area 151 and the second accommodation area 152 are simultaneously arranged as an example for illustration, but it can be understood that, in other embodiments, only the camera 120 can protrude outward relative to the light machine module 130 to form the accommodation area 150 near the light machine module 130, or only the light machine module 130 can protrude outward relative to the camera 120 to form the accommodation area 150 near the camera 120, and the embodiment does not limit it.

[0097] In some embodiments, in addition to the camera 120, the light machine module 130 and the control device 140 described above, referring to Figure 8 , the optical display assembly 100 can further include a connecting assembly 160 for connecting to a spectacle frame. Here, the spectacle frame can be a spectacle frame of single-frame glasses, a spectacle frame of multi-frame glasses, or a spectacle frame provided on any head-mounted device. In addition, the spectacle frame can be in the form of a full frame or in the form of a half frame, and the embodiment does not specifically limit it.

[0098] Here, in the prior art AR glasses and the like, the optical display device and the like used to achieve the AR effect are usually arranged on the temple of the AR glasses close to the frame, and the inventors of the present application have found that the optical display device arranged on the temple will affect the field of view of the user. For example, in the state of the user wearing the AR glasses, the optical display device arranged on the right temple is at about the same height as the right eye, and thus a large range of the field of view on the right side of the right eye will be blocked by the optical display device, and the user cannot effectively observe the environment on the right side in use, which not only affects the use experience but also easily causes safety hazards. Similarly, the optical display device arranged on the left temple will also affect the field of view on the left side of the left eye of the user, and this will not be described here again.

[0099] In the embodiments of the present application, the connecting assembly 160 is arranged on the side of the accommodating shell 110 away from the first direction X to be connected to the frame, and the connecting assembly 160 is used to be connected to the upper edge, the lower edge or the frame edge close to the side of the nose bridge of the frame.

[0100] When the connecting assembly 160 is used to be connected to the upper edge or the lower edge of the frame, in the use state, the main part of the optical display assembly 100 is basically not located at the same height as the eyes of the user, but is located on the upper side or the lower side of the eyes. For example, when the connecting assembly 160 is connected to the upper edge of the frame, the accommodating shell 110 and the components in the accommodating shell 110 of the optical display assembly 100 are basically located at a height higher than the eyes of the user, and the field of view on the left and right sides of the height of the eyes is less blocked, and the imaging unit 133 extending outward from the accommodating shell 110 is located on the front side of the eyes and will not cause the field of view on the left and right sides of the eyes to be blocked. Moreover, as described above, due to the structural design of the present application, the optical display assembly 100 provided by the embodiments of the present application has the advantages of compact structure and miniaturization, and thus when arranged on the frame, the optical display assembly 100 also has less blocking of the field of view on the left and right sides of the eyes of the user. Of course, when the connecting assembly 160 is connected to the upper edge of the frame, the optical display assembly 100 may block the field of view on the upper side of the eyes of the user, but compared with the left and right sides of the height, there are fewer obstacles in the environment on the upper side, and there are more obstacles on the left and right sides, and thus the demand for ensuring the clear field of view on the left and right sides is more important. When the connecting assembly 160 is connected to the lower edge of the frame, the situation is similar, which will reduce the blocking of the field of view on the left and right sides of the height, although it may affect the area on the lower side of the eyes, but there are more obstacles on the left and right sides, and thus the demand for ensuring the clear field of view on the left and right sides is more important.

[0101] In the case that the connecting assembly 160 is used to connect at the position of the frame close to the nose bridge, it also does not block the field of view of the left eye on the left side and / or the right eye on the right side. Although this kind of arrangement can block the field of view of the left eye close to the right side, this side field of view can be mainly realized through the right eye, and the blocking has little effect. Similarly, it can also block the field of view of the right eye close to the left side, but this side field of view can be mainly realized through the left eye, and the blocking has little effect.

[0102] It can be known that the optical display assembly 100 provided in the embodiment is used to be arranged on the frame, and compared with being arranged on the temple, the optical display assembly 100 has less effect on the field of view blocking of the user, which helps to improve the use experience of the user and reduce the safety hazard.

[0103] In addition, it can be understood that the connecting assembly 160 is arranged on the accommodating shell 110 in the embodiment, and in other embodiments, for example, when the optical display assembly 100 does not have the accommodating shell 110, the connecting assembly 160 can be arranged on other components of the optical display assembly 100, and the embodiment does not limit this.

[0104] Here, please continue to refer to Figure 8 The connecting assembly 160 includes a fixing member 161 used to be connected with the frame. The connection mode between the fixing member 161 and the frame is generally a connection mode facilitating disassembly and installation, so as to be installed on and disassembled from the frame. Of course, in other embodiments, the fixing member 161 can also be fixed on the frame in a disassembly-unfriendly manner. Exemplarily, the fixing member 161 extends along the second direction Y and forms a detachable connecting portion 1611. The detachable connecting portion 1611 has a connecting groove 1612 concave in the second direction Y. The fixing member 161 can be clamped and matched on the frame through the connecting groove 1612, for example, clamped and matched on the upper edge, lower edge or side edge of the frame. Please refer to Figure 12 which shows a schematic view of the connecting groove 1612 matched on a first frame 310. Of course, in other embodiments, the connecting groove 1612 can be hung on the upper edge of the frame only, and at this time, the connecting groove 1612 can not be clamped with the frame. Alternatively, the connecting groove 1612 can be used to be hung on the lower edge or side edge of the frame, but at this time, a connecting member needs to be additionally arranged to realize the fixation of the connecting groove 1612 and the frame. Of course, it can be understood that for any of the foregoing embodiments and other embodiments, a connecting member can also be additionally arranged, which can be used to ensure the stable connection between the connecting groove 1612 and the frame.

[0105] Here, the connecting piece can be a connecting pin, a connecting screw, etc., and the present embodiment does not make specific limitation thereto. Correspondingly, the frame and / or the detachable connecting part 1611 can be provided with a hole 1613 for matching the connecting piece. For example, the frame and the detachable connecting part 1611 are provided with corresponding holes 1613, and the connecting piece passes through the corresponding holes 1613 to fix the connecting groove 1612 to the frame. For another example, only the detachable connecting part 1611 is provided with a hole 1613, the hole 1613 is located on the side of the connecting groove 1612 in the first direction X or the reverse direction of the first direction X, and the hole 1613 is arranged along the first direction X. At this time, the connecting piece passes through the hole 1613 on the detachable connecting part 1611 and contacts the frame, and applies a force along the first direction X to the frame to make the frame abut against the inner wall of the connecting groove 1612 on the side of the first direction X of the frame, thereby fixing the connecting groove 1612 to the frame.

[0106] Of course, the structure of the detachable connecting part 1611 of the fixing part 161 is not limited to this, for example, the detachable connecting part 1611 can not have the connecting groove 1612, only the hole 1613 is provided on the detachable connecting part 1611, and then the frame is clamped between the screw and the gasket to realize the matching of the detachable connecting part 1611 and the frame. Moreover, in other embodiments, the detachable connecting part 1611 can also be connected with the frame by magnetic attraction, magic tape connection or clamping, etc., and the present embodiment does not make limitation thereto.

[0107] Further, please refer to Figure 8In some embodiments, the connecting assembly 160 further comprises a movable component 162 disposed on the accommodating shell 110 and configured to cooperate with the fixed component 161. Exemplarily, the fixed component 161 has a guide hole 1614, and the movable component 162 correspondingly has a guide shaft 1621, both of which extend along the third direction Z, the guide hole 1614 can or can not extend through the fixed component 161 along the third direction Z, and the guide shaft 1621 is fitted into the guide hole 1614. Here, the guide shaft 1621 can move left and right relative to the guide hole 1614 along the third direction Z, and thus the movable component 162 can move left and right relative to the fixed component 161 along the third direction Z. In actual use, the movable component 162 and the components such as the accommodating shell 110 and the optical engine module 130 fixed relative to the movable component 162 can move left and right along the third direction Z with the movable component 162, so as to move the center of the imaging unit 133 of the optical engine module 130 to a position corresponding to the center of the pupil of the human eye, thereby facilitating the user to observe the optical image presented by the imaging unit 133. Specifically, when the optical display module is applied to a binocular display scenario, the front side of the user's eyes is respectively provided with the optical display assembly 100 and the imaging unit 133, and the user can adjust the positions of the two optical display assemblies 100 and the imaging unit 133 according to the distance between the pupils of the user's eyes, and thus move the centers of the two imaging units 133 to positions corresponding to the centers of the pupils of the two eyes. When the optical display module is applied to a monocular display scenario, the front side of the user's eye is provided with only the optical display assembly 100 and the imaging unit 133, and it is only necessary to adjust the single imaging unit 133 to move to a position corresponding to the center of the pupil of the eye. At this position, the user can conveniently observe the overall appearance of the optical image presented by the imaging unit 133. Of course, in actual use, the user can adjust the position of the imaging unit 133 along the third direction Z according to the user's needs, and it is not limited to adjusting to a position corresponding to the center of the pupil of the eye.

[0108] It can be seen that, in the embodiments of the present application, the position of the imaging unit 133 of the optical engine module 130 can be adjusted left and right along the third direction Z according to the needs of the user. Compared with the optical display device having the imaging unit 133 fixedly arranged, the optical display assembly 100 in the embodiments of the present application can adjust the imaging unit 133 according to the position of the user's eye, which is helpful to adapt to the actual needs of the user, achieve better use effect and improve the use experience of the user.

[0109] Meanwhile, in the embodiment of the present application, the movable member 162 is fitted in the guide hole 1614 of the fixed member 161 through the guide shaft 1621, the guide shaft 1621 can not only move left and right along the third direction Z, but also rotate along the axial direction of the guide shaft 1621 relative to the guide hole 1614, i.e. the guide shaft 1621 can rotate relative to the guide hole 1614 with the straight line where the axis of the guide shaft 1621 lies as the rotation axis, and further the movable member 162 can rotate relative to the fixed member 161. Here, the optical display assembly 100 can switch between the first position and the second position. In the first position, the imaging unit 133 of the optical display assembly 100 is located in front of the eyes of the user; in the second position, the imaging unit 133 of the optical display assembly 100 is located on the upper side of the eyes of the user, and exemplarily, the imaging unit 133 reaches the second position after being rotated upward by 90° from the position in front of the glasses of the user. Of course, in other embodiments, the second position can also be a position reached after the imaging unit 133 is rotated upward by other angles, such as 10°, 20°, 30°, 45°, 60°, 70°, etc., and it can be understood that the present embodiment does not show all examples of the rotation angle.

[0110] It can be seen that when the optical display assembly 100 is not used or in other cases where it is necessary to adjust the position of the imaging unit 133, the movable member 162 can be rotated to drive the imaging unit 133 away from the position in front of the eyes of the user, so as to avoid the imaging unit 133 from blocking the field of view of the user.

[0111] In the above embodiment, the movable member 162 has the guide shaft 1621, and the fixed member 161 has the guide hole 1614, and further the movable member 162 and the fixed member 161 are fitted with each other and can move relative to each other along the third direction Z. However, in other embodiments, the movable member 162 can have a guide hole and the fixed member 161 can have a guide shaft. Alternatively, in other embodiments, the fitting connection between the movable member 162 and the fixed member 161 can also be realized through other ways, exemplarily one of the movable member 162 and the fixed member 161 has a sliding block and the other has a sliding groove, the sliding block can be fitted in the sliding groove and move along the third direction Z. It can be understood that the present embodiment does not limit the specific fitting way between the movable member 162 and the fixed member 161, as long as they can move relative to each other along the third direction Z.

[0112] In the above embodiment, the switching of the optical display assembly 100 between the first position and the second position is achieved by the guide shaft 1621 and the guide hole 1614, but it can be understood that in other embodiments, it can also be achieved by other means, and the present embodiment does not specifically limit it. For example, the connecting assembly 160 includes a hinge, the accommodating shell 110 is rotatably connected to the movable part 162 through the hinge, the movable part 162 is fitted on the fixed part 161, the fixed part 161 is connected to the frame, and the accommodating shell 110 can be rotated relative to the frame, which can also achieve the switching of the optical display assembly 100 between the first position and the second position.

[0113] Further, please continue to refer to Figure 8 , the connecting assembly 160 further includes a positioning part 163, which cooperates the movable part 162 and the fixed part 161. Here, the connecting assembly 160 has a first state and a second state, in the first state, the positioning part 163 relatively fixes the movable part 162 and the fixed part 161; in the second state, the movable part 162 and the fixed part 161 can relatively move and / or rotate.

[0114] For example, the positioning part 163 is a fixed screw, and screw holes are correspondingly provided on the fixed part 161 and the movable part 162, and the fixed screw can pass through the screw holes on the fixed part 161 and the movable part 162 to fixedly cooperate the movable part 162 and the fixed part 161. At this time, the connecting assembly 160 is in the first state. When the fixed screw is separated from the screw holes of the movable part 162 or the fixed part 161, the fixed cooperation between the fixed part 161 and the movable part 162 is released, and the movable part 162 can move and / or rotate relative to the fixed part 161.

[0115] Of course, it can be understood that in other embodiments, for example, in the case of Figure 8 the fixed part 161 has the guide hole 1614, the movable part 162 has the guide shaft 1621, or in the case of the fixed part 161 has the guide shaft 1621, the movable part 162 has the guide hole 1614, the screw holes can be provided on the guide shaft 1621 and the guide hole 1614 as in the above embodiment, or only one side of the guide hole 1614 can be provided with a screw hole, and the fixed screw can move along the radial direction of the guide hole 1614 to enter the screw hole and fix the guide shaft 1621, and can move along the radial direction of the guide hole 1614 to leave the screw hole and release the guide shaft 1621, and after the fixed screw enters the screw hole, it can apply a force to the guide shaft 1621 pointing to the other side of the guide hole 1614, so that the guide shaft 1621 is fixed in the guide hole 1614. In addition, the fixed screw in the above embodiment can be replaced by a bolt, and the corresponding screw hole can be replaced by a through hole.

[0116] And, in other embodiments, the positioning member 163 is not limited to a fixed screw, and can be a Velcro structure, a magnetic attraction structure, or a clamping structure, etc. In these cases, the positioning member 163 has a first sub-portion and a second sub-portion, which are respectively located on the movable member 162 and the fixed member 161, and can form a releasable mating connection. For example, one of the first sub-portion and the second sub-portion is a Velcro surface, and the other is a Velcro hook surface, which can be mated to each other to place the connection assembly 160 in the first state, and can be released to place the connection assembly 160 in the second state. For another example, one of the first sub-portion and the second sub-portion is an electromagnet, and the other is an iron sheet, which can be attracted to each other when the electromagnet is powered on to place the connection assembly 160 in the first state, and can be released when the electromagnet is powered off to place the connection assembly 160 in the second state.

[0117] Here, the state change of the connection assembly 160 in the application process of the optical display assembly 100 is exemplarily shown.

[0118] When starting to use, the user can switch the connection assembly 160 to the second state, at which time the movable member 162 and the fixed member 161 can be relatively moved, and the user adjusts the position of the movable member 162 to adjust the imaging unit 133 directly or indirectly connected to the movable member 162 to the front position of the user's eyes, i.e., to adjust the optical display assembly 100 to the first position. Thereafter, the user can switch the connection assembly 160 to the first state to keep the optical display assembly 100 in the first position.

[0119] After use, the user can switch the connection assembly 160 to the second state, at which time the movable member 162 and the fixed member 161 can be relatively rotated, i.e., the optical display assembly 100 can be rotated relative to the frame, and the user can rotate the optical display assembly 100 to the second position on the upper side of the eyes, and then adjust the connection assembly 160 to the first state to keep the optical display assembly 100 in the second position.

[0120] In some embodiments, referring to Figure 9 , the optical display assembly 100 further includes a handheld end 170, and the control device 140 further includes a data processing module in signal connection with the data conversion module. As described above, the data conversion module is used to convert the signal into a format readable and writable by the optical-mechanical module 130, and here, the data processing module is mainly used to process the image information and / or other information obtained by the camera device 120 to generate a signal supplied to the data conversion module. For example, the data processing module includes a processor and a readable and writable memory, and the readable and writable memory can be used to store a preset algorithm program.

[0121] Here, the data processing module and the data conversion module can be connected through wired or wireless mode, and the embodiment is not limited thereto. When connected through wired mode, the optical display assembly 100 further comprises a connecting line 180 connected between the accommodating shell 110 and the handheld end 170 for connecting the data processing module and the data conversion module, for example, the connecting interface 1421 of the aforementioned second control circuit can be used to connect the connecting line 180.

[0122] Here, exemplarily, please refer to Figure 11 The connecting line 180 is provided with a detachable fixing part 181 for detachably connecting to a temple, so that the connecting line 180 is easy to be arranged and not easy to move to the frame position when the user uses, so as to avoid affecting the user's field of view. Here, the detachable fixing part 181 can be adapted to the temple to realize magnetic attraction, magic tape cooperation, clamping cooperation, etc. Exemplarily, the detachable fixing part 181 is a magnet, and the temple is correspondingly provided with an iron sheet or a magnet, so that the detachable connection between the connecting line 180 and the temple can be realized through the magnetic attraction force of the magnet and the iron sheet or the magnet. Exemplarily, the detachable fixing part 181 is a magic tape hook surface, and the temple is correspondingly provided with a magic tape hair surface, and the magic tape hook surface can cooperate with the magic tape hair surface to realize the detachable connection between the connecting line 180 and the temple. Exemplarily, the detachable fixing part 181 is a clamping hook, and the temple is correspondingly provided with a clamping groove, and the clamping hook can be clamped with the clamping groove to realize the detachable connection between the connecting line 180 and the temple. Of course, the detachable fixing part 181 is not limited to the above-mentioned embodiments, and the specific structure of the detachable fixing part 181 is not limited in the embodiment.

[0123] Here, the data conversion module, the camera 120 and the optical mechanical module 130 are arranged at the accommodating shell 110, and the data processing module is arranged at the handheld end 170. It can be known that the data processing module and the data conversion module are arranged separately in the embodiment, the data processing module is located at the handheld end 170, and the data conversion module is located at the accommodating shell 110 worn by the user, so that the volume and weight of the accommodating shell 110 are reduced. At the same time, compared with arranging the data processing module and the data conversion module in the accommodating shell 110, only the data conversion module is arranged in the accommodating shell 110, and the heat generation is reduced accordingly. When the user wears the accommodating shell 110, the user experience is better.

[0124] Of course, it can be understood that in other embodiments, the data processing module and the data conversion module can also be arranged in the accommodating shell 110, but the user experience will not be as good as the aforementioned embodiment.

[0125] Further, please refer to Figure 9On the handheld end 170, various operation elements can be arranged, such as an operation knob 171, a touch panel 172, a mechanical key, and the like. As mentioned above, the data processing module of the control device 140 is located on the handheld end 170. Here, the operation elements are connected to the data processing module of the control device 140 located on the handheld end 170 to realize the control function. For example, the operation knob 171 is arranged on the handheld end 170 along the circumference, and the imaging size of the light engine module can be adjusted by rotating the operation knob 171. For another example, the touch panel 172 is arranged on the handheld end 170, and the user can realize the corresponding operation according to the preset algorithm program by operating the touch panel 172.

[0126] In addition, the handheld end 170 can also be provided with communication units, SD cards, players, microphones, and the like to realize corresponding functions. Those skilled in the art can select the arrangement of these specific components, and the present embodiment will not be described in detail. In addition, the handheld end 170 can also be provided with a back clip or the like so as to be connected to the user's neck or other positions.

[0127] The optical display assembly 100 shown in the foregoing embodiments can be applied to a smart head-mounted device 1000 to realize AR, VR, and the like. Therefore, correspondingly, please refer to Figure 10 to Figure 12 In the embodiments of the present application, a smart head-mounted device 1000 is also provided, which comprises the spectacle frame assembly 300 and the optical display assembly 100 described above.

[0128] In Figure 10 In the embodiment shown, the spectacle frame assembly 300 comprises a first spectacle frame 310 and a second spectacle frame 320 arranged in sequence along the third direction Z, and the first spectacle frame 310 and the second spectacle frame 320 are respectively provided with spectacle temples. The structure of the spectacle frame assembly 300 is the same as that of the conventional glasses commonly used. In the state that the user wears the spectacle frame assembly 300, the first spectacle frame 310 is the right spectacle frame and the second spectacle frame 320 is the left spectacle frame relative to the user. Here, the first spectacle frame 310 and the second spectacle frame 320 can be provided with lenses or can not be provided with lenses, which is not limited in the present embodiment.

[0129] Of course, it can be understood that the structure of the spectacle frame assembly 300 is not limited to this. In other embodiments, the spectacle frame assembly 300 can only comprise one spectacle frame, which corresponds to the user's any eye. In addition, the spectacle frame assembly 300 can also not be provided with the spectacle temples, for example, the spectacle frame assembly 300 forms the structure of a single spectacle. Alternatively, the spectacle frame assembly 300 can also be other head-mounted devices, such as a helmet, which only needs to comprise at least one spectacle frame.

[0130] In the present embodiment, please continue to refer toFigure 10 The optical display assembly 100 is arranged on the upper edge of the first frame 310, and the camera 120 of the optical display assembly 100 is away from the second frame 320 compared with the optical-mechanical module 130. That is, when the user wears the smart head-mounted device 1000, the camera 120 on the right frame is located on the right side compared with the optical-mechanical module 130 on the right frame. This arrangement helps to reduce the obstruction of the camera 120 to the user's field of view in front, that is, to expand the space range that the user's eyes can see.

[0131] In addition, the optical display assembly 100 can also be arranged on the second frame 320, and the camera 120 on the second frame 320 is away from the first frame 310 compared with the optical-mechanical module 130. That is, when the user wears the smart head-mounted device 1000, the camera 120 on the left frame is located on the left side compared with the optical-mechanical module 130 on the left frame. This arrangement helps to reduce the obstruction of the camera 120 to the user's field of view in front.

[0132] Of course, in other embodiments, the optical display assembly 100 can also be arranged on both the first frame 310 and the second frame 320, and the present embodiment is not limited thereto. In addition, the optical display assembly 100 is not limited to being arranged on the upper edge of the first frame 310 and / or the second frame 320, but can also be arranged on the lower edge or the edge of the first frame 310 and / or the second frame 320.

[0133] In some embodiments, the accommodation shell 110 of the optical display assembly 100 is rotationally connected to the frame assembly 300 through the aforementioned connecting assembly 160, so that the optical display assembly 100 can be switched between the first position and the second position. In the first position, the imaging unit 133 of the optical display assembly 100 is located in front of the user's eyes; in the second position, the imaging unit 133 of the optical display assembly 100 is located on the upper side of the user's eyes.
