Description

Technical Field

[0001] This utility model relates to the field of smart glasses technology, and in particular to the temple assembly, frame, and smart glasses of smart glasses. Background Technology

[0002] Smart glasses include head-mounted devices such as AR (Augmented Reality) glasses, VR (Virtual Reality) glasses, and MR (Mixed Reality) glasses. These glasses have been applied in various fields, greatly facilitating people's lives and work, and enhancing their experience of how technology changes the world.

[0003] In related technologies, taking AR glasses as an example, the optomechanical components used typically need to be precisely aligned with and bonded to the optical waveguide to allow the signal light emitted by the optomechanism to be incident on the waveguide area. Such optomechanical components occupy a significant amount of space outside the waveguide lenses, requiring a specific area to be allocated for them within the entire AR glasses, hindering miniaturization. To achieve a specific angle between the incident light and the waveguide lenses, the optomechanical components are usually secured with sleeves, further increasing the space required and the weight of the AR glasses. Furthermore, because the sleeves of the optomechanical components are bonded to the waveguide lenses, the connecting wires within the components need to be bent and threaded into the temples to electrically connect to the control circuit board. This wiring is complex and prone to dust accumulation. To prevent excessive changes in the position of the connecting wires, the optomechanical components need to maintain relative stability with the temples. The temples are inconvenient to bend relative to the frame, and disassembly between the temples and frame is difficult, limiting the personalization options available for AR glasses and making replacements costly. Utility Model Content

[0004] In view of this, the present invention proposes a temple assembly, frame and smart glasses for smart glasses, aiming to solve at least one of the aforementioned technical problems, and to integrate multiple components in the temple assembly, save layout space, and help to miniaturize the structure, so that the temple assembly and frame can be purchased, replaced and assembled by users as separate modules.

[0005] The first aspect of this utility model discloses a temple assembly for smart glasses, comprising: a temple portion for connecting to a frame; the temple portion includes a temple body, the temple body having an opening at one end facing the frame, a receiving cavity communicating with the opening formed in the temple body, the temple body having a first direction parallel to the surface of the opening, and a second direction forming an acute angle or a right angle with the surface of the opening; an optical engine portion disposed in the receiving cavity, the optical engine portion including a lens portion and an optical engine body, the lens portion and the optical engine body being spaced apart along the first direction in the temple body, the signal light emitted by the optical engine body being adjusted by the lens portion to be emitted outward through the opening; the optical engine body having a first cross-section with the largest cross-sectional size, the optical engine body being fixed to the temple body and the extension direction of the first cross-section being consistent with the second direction.

[0006] As can be seen from the above technical solutions, the temple assembly of the smart glasses proposed in the first aspect of this utility model integrates the optical engine unit into the temple to form an integrated module. This eliminates the need for the optical engine unit to occupy additional space for bonding with the waveguide lens, which is beneficial for the miniaturization, weight reduction, and aesthetics of the smart glasses. Since the largest cross-sectional dimension of the optical engine body is set along the second direction of the temple body, this arrangement eliminates the need to enlarge the cross-section of the temple due to the placement of the optical engine body. This helps to reduce the dimension of the temple along the first direction, allowing for a thinner design of the entire temple assembly, further promoting the miniaturization and weight reduction of the entire smart glasses. This application can adjust the emission angle of the signal light emitted by the optical engine body towards the port and emit it outward through the lens, thus providing the necessary structural basis for the emission of the signal light towards the waveguide lens. The temple assembly of this application is easy to connect to the frame, eliminating the need to directly connect the optical engine unit to the waveguide lens. The temple assembly can be purchased and replaced as a separate module, or it can be retained when the appearance of the smart glasses needs to be changed, saving assembly costs and enhancing personalization options.

[0007] The second aspect of this utility model provides a frame for smart glasses, the frame being used to connect with the temple assembly, the temple assembly being the temple assembly of the smart glasses described in the foregoing embodiment.

[0008] As can be seen from the above technical solution, the frame of the smart glasses proposed in the second aspect of this utility model is easy to connect with the temple assembly. The frame can also be purchased as a separate module by the user, which makes it convenient for the user to change the overall appearance of the smart glasses and form a personalized combination.

[0009] The smart glasses proposed in the third aspect of this utility model include: a frame of the aforementioned embodiments; an optical waveguide lens connected to the frame, the optical waveguide lens including a coupling region; and a temple assembly of the smart glasses of the aforementioned embodiments, the temple assembly being connected to the frame, wherein signal light emitted by the optical engine body is adjusted to the emission angle by the lens section and emitted outward to the coupling region through the port.

[0010] As can be seen from the above technical solutions, the smart glasses proposed in the third aspect of this utility model can realize the transmission of signal light emitted by the optomechanical body to the coupling region, and after propagation in the optical waveguide lens, it is coupled out to the human eye. Because it has the temple assembly and frame of the aforementioned embodiments, it also has the beneficial effects of temples and frames, and can also easily change the appearance. The temple assembly and the frame with the optical waveguide lens can be selected and purchased separately as independent modules, thereby realizing personalized combination and customization, saving users' replacement costs and improving the user experience. The entire smart glasses structure is lightweight and aesthetically pleasing.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0032] Smart glasses include AR glasses, VR glasses, and MR glasses. All three types of glasses include temples, frames, and lenses, and all three types of glasses need to transmit the signal light emitted by the optical engine to the lenses before coupling it into the human eye.

[0033] In related technologies, taking AR glasses as an example, the MicroLED optical engine used in AR glasses typically employs a traditional imaging lens. The lens needs precise alignment with the optical chip, and the lens and optical chip need to be glued together in a sleeve to form an optical engine assembly. The sleeve is then aligned and glued to the waveguide lens to form the front frame optical system of the AR glasses. Since the sleeve needs to be glued to the waveguide lens, sufficient space needs to be left at the "pillar" position of the AR glasses to accommodate the optical engine assembly. In this application, the "pillar" position refers to the areas at both ends of the frame 20 of the AR glasses, which are used to connect the temple assembly 10 and the frame 20. Furthermore, the control circuit board in the temple must maintain a circuit connection with the optical engine assembly. The frame and temples of the AR glasses cannot be disassembled or replaced, resulting in high purchase costs for users who need AR glasses with various appearances, and preventing personalized customization.

[0034] Currently, the image position in AR glasses is determined by the relative angle between the signal light emitted by the optomechanical component and the waveguide lens. A specific angle is typically required, and using a sleeve allows the light emitted by the optical chip to enter the waveguide lens at a specific angle after passing through the lens. When AR glasses combine images from both eyes, a certain amount of structural space is usually required, resulting in a larger "pillar" design. A larger pillar significantly impacts the aesthetics of the glasses, increases their weight, and affects the user's wearing experience.

[0035] AR glasses in related technologies have an optical chip that can emit signal light. The optical chip can convert electrical signals into optical signals. The optical chip is connected to the control circuit board in the temple through an FPC (Flexible Printed Circuit) and a connector. Since the optical engine assembly is connected to the pin, the FPC connector usually needs to be bent to the back of the optical chip. Bending the connector will affect the heat dissipation of the optical chip and increase the height of the optical engine assembly, further increasing the space occupied by the optical engine assembly.

[0036] In view of this, the present invention proposes a temple assembly 10, a frame 20, and a smart glasses 100 to promote the miniaturization, lightweighting, and personalized customization of the smart glasses 100.

[0037] Where there is no conflict, the following embodiments and features can be combined with each other.

[0038] Combination Figures 1 to 5 As shown, an embodiment of the present invention provides a temple assembly 10 for a smart glasses 100, comprising: a temple portion 11 and an optical mechanism portion 12.

[0039] Among them, combined Figure 3 , Figure 4 and Figure 5As shown, the temple 11 is used to connect with the frame 20. The connection methods and structures of the two are diverse and can be selected according to needs.

[0040] like Figure 1 and Figure 2 As shown, the temple portion 11 includes a temple body 111, which is combined with... Figure 4 and Figure 5 As shown, the temple body 111 has an opening 112 at one end facing the frame 20. This opening 112 can connect to the external environment or to the internal accommodating cavity 113. Figure 1 and Figure 4 As shown, a receiving cavity 113 communicating with the opening 112 is formed in the temple body 111. The temple body 111 has a first direction parallel to the surface where the opening 112 is located, that is, the first direction is... Figure 1 The horizontal direction of the temple body 111 shown in the figure; combined with Figure 1 , Figure 2 and Figure 4 As shown, the temple body 111 has a second direction, such as Figure 1 and Figure 3 As shown, the second direction is perpendicular to the plane containing the opening 112. At this point, the second direction is... Figure 1 The longitudinal direction of the temple body 111 shown in the figure; as Figure 2 As shown, the second direction forms an acute angle with the surface containing the opening 112. At this point, the second direction is... Figure 2 The oblique aspect of the temple body 111 shown in the figure, whether the size of the temple body 111 along the longitudinal edge contour or along the oblique edge contour, is greater than the size of the temple body 111 along the transverse edge contour.

[0041] like Figure 1 and Figure 2 As shown, the optical engine unit 12 is disposed in the receiving cavity 113. The optical engine unit 12 includes a lens unit 121 and an optical engine body 122. The lens unit 121 and the optical engine body 122 are spaced apart in the temple body 111 along a first direction. The signal light emitted by the optical engine body 122 is adjusted to the emission angle by the lens unit 121. Figure 4 The port 112 shown emits outwards. The lens 121 and the optical engine body 122 are arranged in a first direction, and the signal light emitted by the optical engine body 122 is able to be emitted outwards from the port 112. By adjusting the relative positions of the optical engine body 122 and the lens 121, the signal light emitted by the optical engine body 122 toward the lens 121 can be emitted outwards from the port 112 at a desired angle, for example, at a specific angle toward the optical waveguide lens 30.

[0042] Furthermore, the optical engine body 122 has a first cross-section with the largest cross-sectional size. The optical engine body 122 is fixed to the temple body 111, and the extension direction of the first cross-section is consistent with the second direction. It should be noted that the cross-section of the optical engine body 122 should be considered as a cross-section perpendicular to its own thickness direction. For example, the bottom surface of the optical engine body 122 is also a cross-section. When the first cross-section with the largest cross-sectional size extends along the second direction, the portion of the optical engine body 122 with the first cross-section is mainly arranged along the larger part of the temple body 111. In this application, by arranging the optical engine part 122 in the aforementioned manner, it is not necessary to design a larger transverse cross-sectional size of the temple body 111 to accommodate the arrangement of the optical engine body 122.

[0043] As can be seen from the above, the temple assembly 10 of the smart glasses 100 proposed in this utility model integrates the optical engine unit 12 into the temple 11 to form an integrated module. This eliminates the need for the optical engine unit 12 to occupy additional space outside the temple 11 and directly connect to the waveguide lens 30, thus eliminating the need for a mounting point. This is beneficial for the miniaturization and weight reduction of the smart glasses 100. Since the optical engine unit 12 is entirely hidden in the temple 11, the temple assembly 10 achieves good integration and a more aesthetically pleasing overall appearance while still ensuring that the optical engine unit 12 can normally emit signal light outwards.

[0044] Since the side with the largest cross-sectional dimension of the optical engine body 122 is arranged along the second direction of the temple body 111, this arrangement eliminates the need to enlarge the cross-section of the temple portion 11 due to the arrangement of the optical engine body 122. This helps to reduce the dimension of the temple portion 11 along the first direction, allowing the entire temple assembly 10 to be designed to be thinner, thereby further promoting the miniaturization and weight reduction of the entire smart glasses 100. In other words, in this application, the placement of the optical engine body 122 is optimized, which helps to reduce the overall arrangement space of the temple assembly 10, thus contributing to the miniaturization of the smart glasses 100.

[0045] This application can adjust the emission angle of the signal light emitted by the optical engine body 122 through the lens section 121 and emit it outward toward the port 112, thereby providing the necessary structural basis for the emission of signal light toward the optical waveguide lens 30, which is conducive to clear imaging after binocular imaging and realizing the ideal image display position.

[0046] The temple assembly 10 of this application is conveniently connected to the frame 20. It eliminates the need to glue the optical engine 12 to the waveguide lens 30. Instead, after assembly between the temple assembly 10 and the frame 20, the optical engine 12 in the temple assembly 10 can be aligned with the waveguide lens 30 to emit signal light. This application allows the temple assembly 10 to be purchased and replaced as a separate module. Alternatively, the temple assembly 10 can be retained when the appearance of the smart glasses 100 needs to be changed, saving assembly costs and enhancing personalization options.

[0047] In some embodiments, such as Figure 1 and Figure 3 As shown, the second direction of the temple body 111 is perpendicular to the plane containing the opening 112, and the second direction is perpendicular to the first direction. The lens part 121 and the optical engine body 122 are respectively connected to the cavity wall of the receiving cavity 113. In these embodiments, the optical engine body 122 is mainly arranged along the longitudinal direction of the temple body 111, and the angle of the reflecting surface of the lens part 121 relative to the optical engine body 122 can be adjusted to change the propagation angle of the signal light in the optical engine body 122 and emit it outward from the opening 112. In a specific embodiment, the cavity wall of the temple body 111 can be provided with a slot or a limiting groove, so that the optical engine body 122 can be fixed in the slot (not shown) or the limiting groove (not shown); similarly, the cavity wall of the temple body 111 can also be provided with a slot (not shown) and a limiting groove (not shown) for fixing the lens part 121, so that the relative position between the optical engine body 122 and the lens part 121 is fixed. In other embodiments, the cavity wall of the temple body 111 and the optical engine body 122 can also be fixed by setting a snap-fit ​​structure or a plug-in structure; similarly, the cavity wall of the temple body 111 and the lens part 121 can also be fixed by setting a snap-fit ​​structure or a plug-in structure.

[0048] In other embodiments, such as Figure 3 As shown, the temple assembly 10 also includes a cylindrical member 13, which is coaxially arranged with the temple body 111 and is fixedly connected to the temple body 111. The optical engine unit 12 is connected to the cylindrical member 13, and the lens unit 121 and the optical engine unit 122 are arranged radially spaced along the cylindrical member 13. That is, the optical engine unit 12 is first adjusted to a relative position within the cylindrical member 13, and then the cylindrical member 13 is placed into the temple body 111 for positioning, so that the position of the optical engine unit 12 relative to the opening 112 is at a preset position, and the signal light emitted by the optical engine unit 122 in the optical engine unit 12 can be emitted outward from the opening 112 after being reflected and transmitted by the lens unit 121, and can be incident on the optical waveguide lens 30 at a certain angle. In a specific embodiment, the cylindrical member 13 can be press-fitted with the cavity wall of the temple body 111 to achieve assembly. A snap-fit ​​or plug-in structure can also be provided between the cylindrical part 13 and the temple body 111 to achieve quick assembly; no restrictions are imposed here.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the area of ​​the cross-section of the temple body 111 along the first direction is smaller than the area of ​​the first cross-section of the optical engine body 122. In other words, the structure of the temple body 111 along the first direction is thinner, and there is no need to expand the cross-sectional size due to the arrangement of the larger optical engine body 122. This also helps to make the overall transverse cross-section of the temple assembly 10 smaller, more compact and lighter.

[0050] In some embodiments, the lens unit 121 is a periscope lens. By setting a periscope lens, the signal light emitted by the optical engine body 122 can be modulated and emitted outward from the port 112 after changing a certain angle. Alternatively, the optical engine unit 12 can be arranged in the receiving cavity 113 and hidden in the temple 11. By adjusting the angle of the periscope lens relative to the optical engine body 122, the angle at which light enters the waveguide lens 30 can be directly adjusted, thereby changing the position of the image. The optical engine unit 12 does not need to occupy external space but is directly set in the temple 11, which helps to reduce the size of the smart glasses 100 and improve its appearance.

[0051] In one embodiment, the lens portion 121 includes Figure 1 and Figure 2 The reflective prism 1211 or mirror (not shown) is arranged with its reflective surface facing the emitting end of the optomechanical body 122, so that the light emitted from the emitting end is adjusted to the emission angle and emitted through the port 112. The tilt angle of the reflective surface of the reflective prism 1211 or mirror relative to the first direction, and the tilt angle of the reflective surface relative to the light emitted from the emitting end, can be specifically designed and structurally adjusted according to actual needs, and are not limited here.

[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the lens section 121 also includes a collimating lens 1212, which is disposed between the reflecting prism 1211 and the optomechanical body 122 to collimate the light emitted from the transmitting end and project it onto the reflecting prism 1211; or, the collimating lens 1212 is disposed between the reflecting mirror and the optomechanical body 122 to collimate the light emitted from the transmitting end and project it onto the reflecting mirror. In this application, by providing the collimating lens 1212, the point light source emitted from the transmitting end can be formed into a parallel beam and transmitted to the reflecting prism 1211 or the reflecting surface of the reflecting mirror, thereby forming a beam of light that is emitted outward from the port 112, which is beneficial to improving the propagation efficiency of the signal light from the transmitting end and realizing the directional transmission and efficient utilization of the signal light.

[0053] In some embodiments of this application, such as Figures 1 to 3As shown, the temple assembly 10 also includes a control circuit board 14, which is located on the side of the accommodating cavity 113 away from the opening 112. The optical engine section 12 also includes a wire 123, with its two ends connected to the optical engine body 122 and the control circuit board 14, respectively. In this application, both the optical engine body 122 and the control circuit board 14 are located in the temple assembly 11, which facilitates wiring and makes wiring convenient. The wiring does not require multiple bends, which is beneficial for heat dissipation of the optical engine section 12 and can also extend the service life of the wire 123, thereby improving the working performance of the optical engine section 12.

[0054] In some specific embodiments, the line 123 is an FPC printed circuit with high wiring density, which is conducive to the rapid transmission of signals between the control circuit board 14 and the optical engine body 122. The FPC does not need to be bent and is directly connected to the control circuit board 14 in the temple 11. The FPC printed circuit can also be flexibly arranged and has a stable structure, which can reduce wiring complexity and improve the heat dissipation performance of the optical engine body 122.

[0055] In one embodiment, the optomechanical unit 12 further includes a connector 124, which can form a stable connection between the wire 123 and the control circuit board 14, prevent the wire 123 from detaching from the control circuit board 14, and enable the signal to be reliably and stably transmitted between the control circuit board 14 and the optomechanical unit 122.

[0056] In some embodiments of this application, such as Figure 4 As shown, the temple assembly 10 also includes a transparent protective sheet 15, which is connected to the opening 112. This allows the opening 112 to be sealed, effectively preventing dust and water damage, preventing short circuits in the internal components of the temple 11, and improving the service life and reliability of the optical engine unit 12 and the control circuit board 14 after they are installed in the temple 11.

[0057] In some embodiments of this application, such as Figures 1 to 4 As shown, the temple portion 11 also includes a mounting portion 114, one end of which is connected to the temple body 111, and the other end of which is used to engage with... Figure 5 The frame 20 shown is detachably connected. This effectively improves the installation efficiency of the temple assembly 10 and the frame 20, allowing the two independent components to be quickly assembled into a whole. In a specific embodiment, the mounting part 114 is a mounting ear, and the frame 20 is provided with a mating groove. The mounting ear and the mating groove are connected by screws. By adjusting the tightness of the screws (a type of fastener), a certain hinged fit can be formed between the mounting part 114 and the frame 20. In other embodiments, the mounting part 114 can also form a plug-in fit structure or a snap-fit ​​fit structure with the frame 20, or at least two of the following forms of connection: plug-in fit structure, snap-fit ​​fit structure, and detachable fit structure achieved by fasteners. No limitation is imposed here.

[0058] In some embodiments of this application, such as Figure 5 As shown, the temple portion 11 also includes an ear loop portion 115. The ear loop portion 115 is designed with a certain arc. One end of the ear loop portion 115 is connected to the temple body 111, and the other end of the ear loop portion 115 is formed as a free end. The ear loop portion 115 is convenient to wear on the user's ears.

[0059] The frame 20 of this application will now be described.

[0060] like Figure 5 As shown, this utility model proposes a frame 20 for a smart glasses 100. The frame 20 is used to connect with the temple assembly 10, which is the temple assembly 10 of the smart glasses 100 described in the foregoing embodiments.

[0061] As can be seen from the above, the frame 20 of the smart glasses 100 proposed in this utility model is easily connected to the temple assembly 10. The frame 20 can also be purchased as a separate module, allowing users to easily change the overall appearance of the smart glasses 100 and create a personalized combination. Specifically, the frame 20 can be connected to the waveguide lens 30 and sold together with it to the user, thereby changing the appearance of the smart glasses 100. Users can select the desired appearance of the frame 20 and the waveguide lens 30 and assemble them with the previously purchased temple assembly 10 to achieve personalized combination needs. In other words, the frame 20 and the waveguide lens 30 of this application, when assembled, form a front frame assembly, the appearance of which can be changed, creating a product that meets the user's needs for purchase.

[0062] In some embodiments, the frame 20 and temple assembly 10 of this application are connected by a detachable structure. This detachable structure can be a snap-fit ​​structure, a plug-in structure, or a fastener connection structure, allowing users to easily replace the frame 20 with different waveguide lenses 30, thus improving the user experience. This enhances the customizability and replaceability of the frame 20. In a specific embodiment, the frame 20 is detachably connected to the mounting portion 114 of the aforementioned temple assembly 10.

[0063] The smart glasses 100 of this application will now be described.

[0064] like Figure 5 As shown, this utility model proposes a smart glasses 100, including: the frame 20, the waveguide lens 30 of the aforementioned embodiment, and the temple assembly 10 of the smart glasses 100 of the aforementioned embodiment.

[0065] The optical waveguide lens 30 is connected to the frame 20, and the optical waveguide lens 30 includes a coupling region; the temple assembly 10 is connected to the frame 20, and the signal light emitted by the optical engine body 122 is adjusted at the emission angle by the lens section 121 and emitted outward to the coupling region through the port 112. It can be understood that the coupling region can couple the signal light into the optical waveguide lens 30 for total internal reflection propagation, and the optical waveguide lens 30 may also include a coupling region, which couples the light propagating in the optical waveguide lens 30 out to the human eye.

[0066] As can be seen from the above, the smart glasses 100 proposed in this utility model can realize the transmission of signal light emitted by the optical engine body 122 to the coupling area, and after propagation in the optical waveguide lens 30, it is coupled out to the human eye. Because it has the temple assembly 10 and the frame 20 of the aforementioned embodiments, it also has the beneficial effects of the temple assembly 10 and the frame 20, and can also easily change the appearance. The temple assembly 10 and the frame 20 with the optical waveguide lens 30 can be selected and purchased separately as independent modules, improving the customizability and replaceability of the frame 20 and the optical waveguide lens 30, thereby realizing personalized combination and customization, saving users' replacement costs and improving the user experience. The entire smart glasses 100 has a lightweight structure and an aesthetically pleasing appearance.

[0067] The optical waveguide lens 30 of this application has high light transmission efficiency, clear and stable imaging, and can be designed to be relatively thin, which can further realize the lightweight design of the smart glasses 100.

[0068] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
