[0030] Figure 20 This is an application scenario diagram of the wearable device provided in the embodiments of this application. Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] This application provides a wearable device, which typically includes electronic components such as batteries, projection components, and sensors. The wearable device can perform preset functions based on user operation. These preset functions can be displayed via the projection component, or sound emitted via a speaker. The wearable device may include a display device and a preset object. The display device is detachably connected to the preset object, which may be glasses, a helmet, a headband, or other objects wearable on the human body. The following description uses glasses as the preset object.

[0033] For example, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a first structure of a wearable device provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows an exploded view of the wearable device. The wearable device 20 may include an eyeglass structure and a display device. The eyeglass structure may include a frame 200, and the display device may include a functional component 400 and an optical component 600.

[0034] The frame 200 serves as the main frame of the wearable device 20, supporting the functional components 400, optical components 600, and other components. The frame 200 may include a frame body 220 and first temples 240 and second temples 260 respectively connected to opposite sides of the frame body 220. The user can use the first temples 240 and second temples 260 to wear the wearable device 20 on their head.

[0035] For example, the frame body 220 may have a first side 222 and a second side 224 disposed opposite to each other. The first temple 240 is rotatably connected to the first side 222 via a rotating member, allowing the first temple 240 to switch between an open and folded state. The second temple 260 is driveably connected to the second side 224 via a rotating member, allowing the second temple 260 to switch between an open and folded state. When the user needs to use the wearable device 20, the first temple 240 and the second temple 260 of the wearable device 20 can be manually or electrically driven to rotate outwards towards the wearable device 20, so that both the first temple 240 and the second temple 260 are in the open state. Figure 1 As shown. When the user does not need to use the wearable device 20, the inside of the wearable device 20 can be rotated manually or electrically so that both the first temple 240 and the second temple 260 are in a folded state, making it convenient for the user to store the wearable device 20.

[0036] The frame body 220 also has mounting holes 226, into which the optical component 600 can be detachably mounted. For example, the wall of the mounting hole 226 can be provided with a slot, into which the optical component 600 can be snapped. In this embodiment, the frame body 220 may have two mounting holes 226, such as a first mounting hole and a second mounting hole, with the first mounting hole adjacent to the first temple 240 and the second mounting hole adjacent to the second temple 260. The functional component 400 is detachably connected to the first temple 240 or the second temple 260, and the optical component 600 is detachably mounted to the first mounting hole or the second mounting hole.

[0037] In this embodiment, the functional component 400 may include multiple functional modules to achieve various functions. For example, the functional component 400 may include a display module 420, which may include a display and a matching lens assembly. The display can emit effective light signals. The display can emit light, wherein the light signal that generates the virtual image is the effective light signal. The effective light signal can be emitted to the optical component 600, and the optical component 600 can transmit the effective light signal to the user's retina to form a virtual image on the retina, thereby enabling the user to view the virtual image. Of course, the functional component 400 may also include a camera, a speaker, a battery, or other functional modules.

[0038] The display can be a microdisplay, such as an Organic Light-Emitting Diode (OLED) display or a Liquid Crystal Display (LCD). Under operating power conditions, the brightness of a Micro-OLED is less than 5000 nits, and the brightness of an LCD is less than 15000 nits. The display in this embodiment can also be a Micro Light-Emitting Diode (Micro-LED) display, such as a green Micro-LED, or other monochrome Micro-LEDs or white polychromatic Micro-LEDs. Compared to Micro-OLED and LCD, the brightness of Micro-LED can reach 2,000,000 nits, far exceeding that of Micro-OLED and LCD. Furthermore, since Micro-LED is a self-emissive light source, projection systems using Micro-LED have better contrast and lower display latency.

[0039] The functional component 400 is detachably connected to either the first temple 240 or the second temple 260. For example, there can be one functional component 400, which the user can install on either the first temple 240 or the second temple 260 as needed. Alternatively, there can be two functional components 400, in which case the user can install one functional component 400 on the first temple 240 and the other functional component 400 on the second temple 260. Or, there can be three, four, or other numbers of functional components 400, in which case the user can install some of the functional components 400 on the first temple 240 and others on the second temple 260.

[0040] Understandably, when the user does not need to use the functional component 400 and / or the optical component 600, the functional component 400 and / or the optical component 600 can be removed, allowing the frame 200 to be separated from the functional component 400 and / or the optical component 600. In this case, the wearable device 20 can be used as a regular frame, and the wearable device 20 with the functional component 400 and / or the optical component 600 removed is lighter and more convenient for daily wear. When the user needs to use the functional component 400 and / or the optical component 600, the functional component 400 and the optical component 600 can be reinstalled on the frame 200, and the functional component 400 and the optical component 600 can be used to achieve the functions the user wants, such as viewing virtual images, taking photos or videos, or listening to music.

[0041] For example, the functional component 400 can be magnetically attached to the first temple 240 or the second temple 260. Exemplarily, the first temple 240 is magnetic (e.g., part or all of the first temple 240 can be made of magnetic material, or the first temple 240 can be provided with a magnet, or the first temple 240 can be an electromagnet), the functional component 400 can be magnetic, and the magnetism of the functional component 400 is opposite to that of the first temple 240, so the functional component 400 can be magnetically attached to the first temple 240.

[0042] The second temple 260 may also be magnetic (e.g., part or all of the second temple 260 may be made of magnetic material, or the second temple 260 may be provided with a magnet, or the second temple 260 may be an electromagnet). The magnetism of the second temple 260 is opposite to that of the functional component 400, and the functional component 400 may be magnetically attracted to the second temple 260.

[0043] In some other embodiments, the first temple 240 or the second temple 260 may be magnetic, and the functional component 400 may be magnetically attached to the first temple 240 or the second temple 260.

[0044] For example, the first temple 240 is magnetic (e.g., part or all of the first temple 240 may be made of magnetic material, or the first temple 240 may be provided with a magnet, or the first temple 240 may be an electromagnet), and the functional component 400 may have a first metal part (e.g., part of the functional component 400 may be made of metal material, or all of the functional component 400 may be made of metal material), and the first metal part may be attracted to the first temple 240.

[0045] The second temple 260 may also be magnetic (e.g., part or all of the second temple 260 may be made of magnetic material, or the second temple 260 may be provided with a magnet, or the second temple 260 may be an electromagnet), and the first metal part of the functional component 400 may also be attracted to the second temple 260.

[0046] In some other embodiments, the functional component 400 may be magnetic, and a functional component 400 may be magnetically attached to the first temple 240 or the second temple 260.

[0047] For example, the first temple 240 may have a second metal portion (such as a portion of the first temple 240 may be made of a metal material, or the entire first temple 240 may be made of a metal material), the functional component 400 may be magnetic (such as a portion or all of the functional component 400 may be made of a magnetic material, or the functional component 400 may be provided with a magnet, or the functional component 400 may be an electromagnet), the second metal portion may be attracted to the functional component 400, or in other words, the functional component 400 may be fixed to the first temple 240 by the second metal portion.

[0048] The second temple 260 may have a second metal part (such as a part of the second temple 260 may be made of metal material, or the entire second temple 260 may be made of metal material), the functional component 400 is magnetic (such as a part or all of the functional component 400 may be made of magnetic material, or the functional component 400 may be provided with a magnet, or the functional component 400 may be an electromagnet), the second metal part may be attracted to the functional component 400, or in other words, the functional component 400 may be fixed to the second temple 260 by the second metal part.

[0049] In some other embodiments, one of the first temple 240 and the second temple 260 may have a second metal portion, which may be adsorbed onto the functional component 400.

[0050] It should be noted that in some other embodiments, the functional component 400 can also be connected to the first temple 240 or the second temple 260 in other ways. For example, the functional component 400 may be provided with a snap-fit ​​portion or a clamping portion, allowing it to be snapped onto the first temple 240 or the second temple 260 via the snap-fit ​​portion, or clamped onto the first temple 240 or the second temple 260 via the clamping portion. Alternatively, the functional component 400 may be provided with a strap, allowing it to be secured to the first temple 240 or the second temple 260 via the strap. Yet another example is that the functional component 400 may be provided with an elastic collar, allowing it to be fitted onto the first temple 240 or the second temple 260 via the elastic collar. It is understood that the above are examples of how the functional component 400 and the frame 200 can be detachably connected, and should not be construed as limiting the implementation of how the functional component 400 and the frame 200 can be detachably connected. Any implementation that can achieve the detachable connection of the functional component 400 and the frame 200 in the art can be applied to the embodiments of this application, and the embodiments of this application do not limit this.

[0051] The optical component 600 can transmit and / or modulate light. The optical component 600 may include an optical waveguide 620, which is correspondingly positioned with the display module 420 to receive and transmit valid light signals to form a virtual image. It is understood that the optical waveguide 620 can transmit valid light signals emitted by the display module 420 to the user's retina to form a virtual image on the retina, thereby allowing the user to view the virtual image.

[0052] In this embodiment, by detachably connecting the frame 200 and the functional component 400, the user can install the functional component 400 on the frame 200 or remove it from the frame 200 as needed, thereby improving the assembly flexibility of the wearable device 20.

[0053] Among them, the optical waveguide 620 can be a diffraction waveguide, a one-dimensional geometric waveguide, a two-dimensional geometric waveguide, a micro-mirror array waveguide, or other types of optical waveguides.

[0054] For example, such as Figure 3 As shown, Figure 3 for Figure 1 The diagram shows a first structural schematic of the optical waveguide sheet in the wearable device. The optical waveguide sheet 620 includes a substrate 622 and a grating structure 624. The grating structure 624 couples optical signals (such as effective optical signals emitted by the display module 420) into the substrate 622, and the substrate 622 reflects the optical signals onto the retina of the human eye to form a virtual image on the retina. The substrate 622 can serve as a substrate, and the grating structure 624 can be formed on the surface of the substrate 622.

[0055] like Figure 3 As shown, the grating structure 624 may include a first sub-grating structure 6242, a second sub-grating structure 6244, and a third sub-grating structure 6246. The dimensions of the first sub-grating structure 6242, the second sub-grating structure 6244, and the third sub-grating structure 6246 increase sequentially. The first sub-grating structure 6242 can be circular, the second sub-grating structure 6244 can be trapezoidal, and the third sub-grating structure 6246 can be rectangular. Of course, the shapes of the first sub-grating structure 6242, the second sub-grating structure 6244, and the third sub-grating structure 6246 are not limited to these shapes. Figure 3 The shape shown can be designed according to actual needs, and the embodiments of this application are not limited in this respect.

[0056] The second sub-grating structure 6244 is located between the first sub-grating structure 6242 and the third sub-grating structure 6246. The first sub-grating structure 6242 is used to receive the effective light signal emitted by the display module 420 and transmit the received effective light signal to the second sub-grating structure 6244. The second sub-grating structure 6244 is used to receive the effective light signal transmitted by the first sub-grating structure 6242 and transmit the received effective light signal to the third sub-grating structure 6246. The third sub-grating structure 6246 is used to receive the effective light signal transmitted by the second sub-grating structure 6244 and reflect the received effective light signal to the retina of the human eye.

[0057] In this embodiment, by setting three sub-grating structures of different sizes, the area of ​​the grating structure 624 can be reduced, thereby saving costs, compared to directly designing the size of the grating structure to be the same as that of the substrate 622.

[0058] like Figure 4 As shown, Figure 4 for Figure 1 The diagram shows a second structural representation of the optical waveguide sheet in the wearable device. The optical waveguide sheet 620 may include multiple planar dielectric layers 626, which may be stacked sequentially along a first direction. The multiple planar dielectric layers 626 can refract and reflect the received effective light signal to the retina of the human eye.

[0059] It should be noted that the configuration of multiple flat dielectric layers 626 is not limited to one method; for example, such as... Figure 5 As shown, Figure 5 for Figure 1The diagram shows a third structural representation of the optical waveguide sheet in the wearable device. A portion of the multiple planar dielectric layers 626 can be stacked sequentially along a first direction, and another portion of the multiple planar dielectric layers 626 can be stacked sequentially along a second direction. The first and second directions are two different directions; for example, the first and second directions can be mutually perpendicular.

[0060] like Figure 6 As shown, Figure 6 for Figure 1 The diagram shows a fourth structural representation of the optical waveguide in the wearable device. The optical waveguide 620 may include a micromirror array 628, which can transmit and modulate the received effective optical signal and reflect the modulated effective optical signal to the retina of the human eye.

[0061] Combination Figure 1 , 2 and Figure 7 As shown, Figure 7 for Figure 1 The diagram shows a first structural schematic of the first lens assembly in the wearable device. The optical assembly 600 may further include a refractive correction lens 640 and a refractive compensation lens 660. An optical waveguide 620 is sandwiched between the refractive correction lens 640 and the refractive compensation lens 660. The refractive correction lens 640 can modulate the effective light signal and the external light signal to modulate the refractive power of the virtual image and the real image, enhancing the display effect of the virtual image and meeting the clear experience requirements of users with myopia or hyperopia. The refractive compensation lens 660 can compensate for the refractive power of the refractive correction lens 640, improving the refractive power modulation effect of the refractive correction lens 640. Both the refractive compensation lens 660 and the refractive correction lens 640 can be injection-molded lenses or glass lenses. The refractive compensation lens 660 and the refractive correction lens 640 can be fixed on the optical waveguide sheet 620 by means of secondary injection molding or 3D printing, or they can be molded by injection molding or cold processing and then glued onto the optical waveguide sheet 620.

[0062] The waveguide sheet 620 has a first surface and a second surface arranged opposite to each other. The first surface is the side closer to the user's eye, and the second surface is the side away from the user's eye. A refractive correction lens 640 is disposed on the first surface, i.e., the refractive correction lens 640 is close to the user's eye. Furthermore, the side of the refractive correction lens 640 that is in contact with the first surface is flat, and the side away from the first surface is concave. A refractive compensation lens 660 is disposed on the second surface, i.e., the refractive compensation lens 660 is away from the user's eye. Furthermore, the side of the refractive compensation lens 660 that is in contact with the second surface is flat, and the side away from the second surface is convex.

[0063] It should be noted that the face shape of the 640 refractive correction lens and the 660 refractive compensation lens can be adjusted according to needs. Figure 7 This is for illustrative purposes only and should not be construed as limiting the face shape of the refractive correction lens 640 and the refractive compensation lens 660.

[0064] In some other embodiments, the optical component 600 may include only a diopter-correcting lens 640 or a diopter-compensating lens 660.

[0065] In the above embodiments, since both the diopter correction lens 640 and the diopter compensation lens 660 are fixed on the waveguide sheet 620, each diopter correction lens 640 has only one diopter correction value and each diopter compensation lens 660 has only one diopter compensation value, and they cannot be adjusted according to the user's actual vision.

[0066] Based on this, this application embodiment, starting from practical application, improves the refractive correction lens 640 and / or refractive compensation lens 660 by making them detachably mounted in the mounting hole 226. For example, the refractive correction lens 640 is detachably mounted in the mounting hole 226 and covers the first surface of the optical waveguide sheet 620; the refractive compensation lens 660 is detachably mounted in the mounting hole 226 and covers the second surface of the optical waveguide sheet 620. Compared with the above application embodiment, the refractive correction lens 640 and the refractive compensation lens 660 of this application embodiment are detachable from the frame body 220. Users can replace lenses with different refractive correction or different refractive compensation as needed, allowing users to choose different lenses according to their own needs, and also making the wearable device 20 suitable for people with different vision, improving the versatility and adaptability of the wearable device 20. Of course, it is also possible for only the refractive correction lens 640 or the refractive compensation lens 660 to be detachable.

[0067] The structure of the optical component 600 in this embodiment is not limited thereto; for example, as shown below. Figure 8 and Figure 9 As shown, Figure 8 for Figure 1 The diagram shows a second structural representation of the first lens assembly in the wearable device. Figure 9 for Figure 8 The diagram shows an exploded view of the first type of lens assembly. The optical assembly 600 may include the optical waveguide 620 as described in any of the above embodiments and at least one functional lens. The at least one functional lens is detachably mounted in the mounting hole 226, and when the at least one functional lens is mounted in the mounting hole 226, the at least one functional lens is spaced apart from the optical waveguide 620.

[0068] For example, the optical component 600 may include two functional lenses, namely a first functional lens 682 and a second functional lens 684. The functions that the first functional lens 682 can perform and the functions that the second functional lens 684 can perform may be the same or different. The edge of the optical waveguide 620 is provided with a first connecting portion 627 and a second connecting portion 629. The first functional lens 682 may have a third connecting portion 681 and a fourth connecting portion 683. The third connecting portion 681 can be detachably connected to the first connecting portion 627, and the fourth connecting portion 683 can be detachably connected to the second connecting portion 629. For example, both the upper and lower surfaces of the first connecting portion 627 and the second connecting portion 629 may have slots. The third connecting portion 681 can be engaged in the slot on the first connecting portion 627, and the fourth connecting portion 683 can be engaged in the slot on the second connecting portion 629 to realize the connection between the first functional lens 682 and the optical waveguide 620. Of course, the first connecting part 627 and the third connecting part 681, and the second connecting part 629 and the fourth connecting part 683 can also be detachably connected by other means such as screw fastening, clamping, or magnetic adsorption. The first functional lens 682 is also provided with a first electrical connection structure 685, which can be electrically connected to the functional component 400 so that the functional component 400 can control the first functional lens 682 and trigger the first functional lens 682 to perform its function.

[0069] The second connecting portion 629 and the second functional lens 684 may have a fifth connecting portion 686 and a sixth connecting portion 687. The fifth connecting portion 686 can be detachably connected to the first connecting portion 627, and the sixth connecting portion 687 can be detachably connected to the second connecting portion 629. For example, the fifth connecting portion 686 can be engaged in a slot under the first connecting portion 627, and the sixth connecting portion 687 can be engaged in a slot under the second connecting portion 629, thereby connecting the second functional lens 684 to the optical waveguide sheet 620. Of course, the second connecting portion 629, the fifth connecting portion 686, and the sixth connecting portion 687 can also be detachably connected by other methods such as screw fastening, clamping, or magnetic adsorption. The second functional lens 684 is also provided with a second electrical connection structure 688, which can be electrically connected to the functional component 400, so that the functional component 400 can control the second functional lens 684 and trigger the second functional lens 684 to perform its function.

[0070] For example, the first functional lens 682 can be an electrochromic lens, and the second functional lens 684 can be a liquid crystal lens assembly. The electrochromic lens is located on the side of the optical waveguide sheet away from the human eye, and can be attached using convenient methods such as magnetic attraction. During the attachment process, there is always an air gap between the electrochromic lens and the optical waveguide sheet 620. The electrochromic lens has corresponding leads and control interfaces (i.e., the first electrical connection structure 685), which can be electrically connected to the detachable functional component 400 assembled on the first temple 240 or the second temple 260 through methods such as electro-optical attraction, to realize the active or automatic modulation function of the transmittance of external light signals and effective light signals. The liquid crystal lens assembly is located on the side of the optical waveguide sheet 620 closer to the human eye, and can be attached using convenient methods such as magnetic attraction, which can simultaneously realize the refractive power modulation or correction of virtual images and real images. During the attachment process, there is always an air gap between the liquid crystal lens assembly and the optical waveguide sheet 620. The liquid crystal lens group has corresponding leads and control interfaces (i.e., the second electrical connection structure 688), which can be electrically connected to the detachable functional component 400 assembled on the first temple 240 or the second temple 260 through electromagnetism or other means, so as to realize the active or automatic diopter modulation function.

[0071] Of course, the first functional lens 682 and the second functional lens 684 can also be other types of lenses, such as sunglasses lenses, anti-blue light lenses, anti-radiation lenses, or sports lenses.

[0072] It should be noted that the optical component 600 in this embodiment may also include only one functional lens, such as only the first functional lens 682, or only the second functional lens 684.

[0073] It is understood that in the optical component 600 of this application embodiment, the optical waveguide 620 can exist independently to achieve the thinnest and lightest size and weight. The first functional lens 682 and the second functional lens 684 can be used individually or simultaneously on the optical waveguide 620 as needed.

[0074] In other embodiments, the wearable device 20 may include only one lens, rather than a first lens assembly formed by combining multiple separate lenses as described in the above-described embodiments. For example, as... Figures 10 to 13 As shown, Figure 10 This is a schematic diagram of a second structure of a wearable device provided in an embodiment of this application. Figure 11 for Figure 10 The diagram shows the exploded structure of the wearable device. Figure 12 for Figure 10 The diagram shows a first structural design of the lens in the wearable device. Figure 13 for Figure 10The diagram shows a second possible structure of a lens in a wearable device. The wearable device 20 may include a lens 800, which can be a prism-shaped spectacle lens based on an aspherical surface, a freeform surface, or its corresponding Fresnel surface. The lens 800 may include a lens body 820 and a conductive structure 840. The conductive structure 840 is disposed on the lens body 820. The lens body 820 receives the effective light signal emitted by the display module 420 and transmits the received effective light signal to the conductive structure 840. The conductive structure 840 reflects the received effective light signal to a preset position. Figure 13 As shown, an effective light signal can enter from near the first temple 240 or the second temple 260 and be reflected within the lens body 820 by the freeform surface within the lens body 820. It then undergoes total internal reflection within the lens body 820, is reflected again through the conduction structure 840, and finally couples out to enter the user's retina. The conduction structure 840 can be a Fresnel reflector. External light signals can enter the user's retina through the conduction structure 840.

[0075] In this embodiment, the frame body 220 may have two mounting holes 226, the number of functional components 400 may be two, and the number of optical components 600 may also be two. One functional component 400 is correspondingly paired with one optical component 600, enabling the wearable device 20 to achieve binocular display. For an example, please refer to... Figure 1 , Figure 2 , Figure 10 and Figure 11 One functional component 400 is detachably mounted on the first temple 240. An optical component 600 is mounted in a mounting hole 226. This optical component 600 can receive effective light signals emitted by the display module 420 in its corresponding functional component 400 and transmit the received effective light signals to one of the user's eyes, such as the left eye. Another functional component 400 is detachably mounted on the second temple 260. Another optical component 600 is mounted in another mounting hole 226. This optical component 600 can receive effective light signals emitted by the display module 420 in its corresponding functional component 400 and transmit the received effective light signals to the user's other eye, such as the right eye, so that both of the user's eyes can view the virtual image, thereby realizing binocular display of the wearable device 20.

[0076] The two functional components 400 can be communicatively connected, enabling them to work collaboratively. For example, please refer to... Figures 14 to 16 , Figure 14 This is a schematic diagram of a third structure of the wearable device provided in the embodiments of this application. Figure 15 for Figure 14The diagram shows the exploded structure of the wearable device. Figure 16 for Figure 14 The diagram shows the structure of the frame and the first glasses assembly in the wearable device. The frame 200 has a connecting portion 280, the first temple 240 has a first connector 242, and the second temple 260 has a second connector 262. The connecting portion 280 connects to the first connector 242 and the second connector 262 respectively. When one functional component 400 is mounted on the first temple 240, it can connect to the first connector 242; when the other functional component 400 is mounted on the second temple 260, it can connect to the second connector 262. This allows the two functional components 400 to establish a communication connection through the connecting portion 280, enabling them to work collaboratively. For example, the two functional components 400 can emit different effective light signals, allowing the two optical components 600 to display different images, such as the left side displaying current road conditions and the right side displaying current vehicle driving information.

[0077] In this configuration, both the first connector 242 and the second connector 262 can be connection contact points, and each of the two functional components 400 is provided with a spring pin, which can contact the connection contact points to achieve electrical connection. Alternatively, both the first connector 242 and the second connector 262 can be spring pins, and each of the two functional components 400 is provided with a connection contact point; or one of the first connector 242 and the second connector 262 can be a connection contact point and the other can be a spring pin, and one of the two functional components 400 can be a spring pin and the other can be a connection contact point.

[0078] Of course, the first connector 242 and the second connector 262 can also be implemented in other ways, such as the first connector 242 and the second connector 262 being electrical connectors, and the two functional components 400 may also be provided with pins, which can be inserted into the electrical connectors and electrically connected to the electrical connectors.

[0079] In other embodiments, the communication connection between the two functional components 400 can also be achieved wirelessly, such as through Bluetooth, Wi-Fi, or near-field communication.

[0080] In this embodiment, both functional components 400 include at least one preset functional module, wherein at least some of the preset functional modules included in one functional component are of a different type than the type of at least one preset functional module included in the other functional component. The at least one preset functional module is one or a combination of several of the following: a battery module, a health monitoring module, a speaker module, and a camera module.

[0081] For example, please refer to Figure 17 , Figure 17 This diagram illustrates an application scenario of the wearable device provided in this embodiment. One functional component 400 may further include a health monitoring module 440, which can monitor real-time health information such as body temperature, pulse, respiratory rate, blood pressure, and blood oxygen. The other functional component 400 may also include a camera module 450, which can perform convenient shooting and spatial awareness functions. Both functional components 400 may also include a battery module, a speaker module, or other functional modules. It is understood that as long as the types of preset functional modules included in the two functional components 400 are not completely identical, for example, one, two, three, or all of the preset functional modules included in one functional component 400 may be different from those in the other functional component 400. In this way, different preset functional modules can be integrated into different functional components 400 according to actual needs, giving the two functional components 400 differentiated functions. Compared to two functional components 400 having the same preset functional modules stacked on top of each other, this embodiment allows functional components 400 to stack more types of functions within a limited space, thereby enabling the wearable device 20 to achieve more functions.

[0082] In some other embodiments, there may be one functional component 400 and two optical components 600, which the user can selectively mount on the first temple 240 or the second temple 260 to view the virtual image with either the left or right eye. Alternatively, there may be two functional components 400, one mounted on the first temple 240 and the other on the second temple 260, and one optical component 600, which can be detachably mounted on either the first or second mounting hole and cooperate with its corresponding functional component 400 to form a virtual image.

[0083] It is understood that embodiments of this application may include two functional components 400 and at least one optical component 600. One functional component 400 is detachably connected to the first temple 240, and the other functional component 400 is detachably connected to the second temple 260. At least one optical component 600 is detachably mounted in the first mounting hole and / or the second mounting hole to transmit the effective light signal emitted by the display module 420 of one functional component 400 and / or the effective light signal emitted by the display module 420 of the other functional component 400.

[0084] It should be noted that in some other embodiments, the types of preset functional modules included in one functional component 400 may be the same as the types of preset functional modules included in another functional component 400. For example, both functional components 400 may include a health monitoring module 440 or both may include a camera module 450.

[0085] In some other embodiments, the number of functional components 400 can be one, the number of optical components 600 can also be one, and the other mounting hole 226 can be used to mount a conventional lens or other types of lenses. For example, Figure 18 As shown, Figure 18 This is a fourth structural schematic diagram of a wearable device provided in an embodiment of this application. The wearable device 20 may further include a lens assembly 900, which does not include the waveguide sheet 620, meaning the lens assembly 900 does not have augmented reality functionality. For example, the lens assembly 900 can be one or a combination of several types of lenses, such as a plano lens, a myopia lens, a hyperopia lens, a sunglasses lens, a blue light blocking lens, an anti-radiation lens, or other types of lenses. The optical component 600 is mounted in one mounting hole 226 to transmit the effective light signal emitted by the display module 420 of a functional component 400, and the lens assembly 900 is mounted in another mounting hole 226. It is understood that in this embodiment of the application, the optical component 600 with augmented reality functionality can be used on a monocular lens, while the other eye lens uses a matching injection-molded lens or glass lens without augmented reality functionality.

[0086] This application also provides a wearable device, such as... Figure 19 As shown, Figure 19 This is a schematic diagram of the structure of a wearable device provided in an embodiment of this application. The wearable device 40 may include glasses 42 and at least three functional components 44.

[0087] The eyeglasses 42 may include a frame 42a and an optical component 42b. The frame 42a may include a frame body and a first temple and a second temple connected to both sides of the frame body. The frame body has mounting holes. The optical component 42b includes an optical waveguide sheet, which is mounted in the mounting holes. The structures of the frame 42a and the optical component 42b can be found in the descriptions of the frame 200 and the optical component 600 in the above-mentioned embodiments, and will not be repeated here.

[0088] The different functional components 44 in the at least three functional components 44 may include different functional modules, and the at least three functional module components are all detachably connected to the first temple or the second temple, and the at least three functional component modules are used to be selectively installed on the first temple and / or the second temple according to user needs.

[0089] For example, the wearable device 40 may include four functional components 44. One functional component 44 may include a battery module 44a, a health monitoring module 44b, a camera module 44c, and a display module 44d. The user can select one or two functional components 44 to install on the frame 42 according to their needs. For example, the user can select the functional component 44 including the health monitoring module 44b to be installed in the first temple and select the functional component 44 including the projection module 44d to be installed in the second temple. Figure 20 As shown, Figure 20 This is an application scenario diagram of the wearable device provided in the embodiments of this application. In this case, the functional component 44 installed on the first temple can monitor the user's current health information through the health monitoring module 44b, and synchronize the health signal to the functional component 44 installed on the second temple. The functional component 44 installed on the second temple can form a virtual image of the user's current health information on the user's retina through the display module 44d, so that the user can see the current health information on the optical component 42b.
