Description

Smart glasses Technical Field

[0001] This application belongs to the field of smart glasses technology, and specifically relates to a smart pair of glasses. Background Technology

[0002] In related technologies, smart glasses typically use air cooling to dissipate heat from the screen components. However, due to the small size and high resolution of the screen components, they generate a lot of heat. Furthermore, due to the size limitations of smart glasses, large fans cannot be used, resulting in poor heat dissipation of the screen components and accelerating the degradation of their lifespan. Summary of the Invention

[0003] The purpose of this application is to provide a smart glasses solution that effectively addresses the technical problem of poor heat dissipation in the screen components of smart glasses.

[0004] This application provides a smart glasses embodiment, including:

[0005] Screen components;

[0006] The heat dissipation component is in contact with the screen component;

[0007] The heat dissipation components include:

[0008] The body has a cavity and a first mounting hole, and the first mounting hole is connected to the cavity.

[0009] A flexible membrane is mounted on the body and located at the first mounting hole;

[0010] The heat-conducting component is mounted on the flexible film and comes into contact with the screen assembly.

[0011] In this embodiment of the application, the smart glasses include a screen assembly and a heat dissipation assembly. The heat dissipation assembly is in contact with the screen assembly, so that the heat from the screen assembly can be transferred to the heat dissipation assembly for heat dissipation.

[0012] The heat dissipation component includes a body, a flexible film, and a heat-conducting component. The body has a cavity and a first mounting hole, which are connected to the cavity. The flexible film is disposed at the first mounting hole, and the heat-conducting component is disposed on the flexible film. Thus, the flexible film and the heat-conducting component can block the first mounting hole, thereby sealing the cavity. Furthermore, the heat-conducting component is in contact with the screen assembly.

[0013] The cavity can be filled with a working fluid, so that the heat of the screen component can be transferred to the working fluid through the heat conduction component, and then the working fluid dissipates the heat through the heat dissipation component. In addition, the working fluid can also absorb heat through phase change, thereby improving the heat dissipation effect of the screen component and reducing the lifespan reduction of the screen component caused by high temperature.

[0014] Furthermore, since there is a flexible membrane between the heat-conducting component and the body, it can adapt to the interpupil distance (IPD) adjustment of smart glasses to a certain extent, reducing the possibility of working fluid leakage in the heat dissipation component and improving the service life of the heat dissipation component.

[0041] The smart glasses 100 according to an embodiment of this application is described below with reference to Figures 1 to 19.

[0042] As shown in Figures 1 to 10, this application embodiment provides a smart glasses 100, including: a screen assembly 110; a heat dissipation assembly 120 in contact with the screen assembly 110; wherein, the heat dissipation assembly 120 includes: a body 122, the body 122 having a cavity 1222 and a first mounting hole 1224, the first mounting hole 1224 and the cavity 1222 being connected; a flexible film 124 disposed on the body 122 and located at the first mounting hole 1224; and a heat-conducting element 126 disposed on the flexible film 124 and in contact with the screen assembly 110.

[0043] In this embodiment of the application, the smart glasses 100 includes a screen assembly 110 and a heat dissipation assembly 120. The heat dissipation assembly 120 is in contact with the screen assembly 110, so that the heat of the screen assembly 110 can be transferred to the heat dissipation assembly 120 for heat dissipation.

[0044] As shown in Figures 2, 5, 6, 7 and 12, the heat dissipation assembly 120 includes a body 122, a flexible film 124 and a heat conductor 126. The body 122 has a cavity 1222 and a first mounting hole 1224, which is connected to the cavity 1222. The flexible film 124 is disposed at the first mounting hole 1224, and the heat conductor 126 is disposed on the flexible film 124. Thus, the flexible film 124 and the heat conductor 126 can block the first mounting hole 1224, so that the cavity 1222 can be sealed. Furthermore, the heat conductor 126 is in contact with the screen assembly 110.

[0045] The cavity 1222 can be filled with a working fluid 160, so that the heat of the screen assembly 110 can be transferred to the working fluid 160 through the heat conductor 126, and the heat can be dissipated through the body 122 of the heat dissipation assembly 120 by the working fluid 160. In addition, the working fluid 160 can also absorb heat through phase change, thereby improving the heat dissipation effect of the screen assembly 110 and reducing the lifespan degradation of the screen assembly 110 caused by high temperature.

[0046] Furthermore, since there is a flexible membrane 124 between the heat-conducting component 126 and the body 122, it can adapt to the interpupillary distance adjustment of the smart glasses 100 to a certain extent, reduce the possibility of leakage of the working fluid 160 in the heat dissipation component 120, and improve the service life of the heat dissipation component 120.

[0047] This application provides a smart glasses 100, whose heat dissipation component 120 has a sealed cavity 1222. The cavity 1222 is filled with a working fluid 160. When heated, the working fluid 160 generates natural convection to enhance the heat dissipation effect, thereby strengthening the heat dissipation of the screen component 110. The heat dissipation component 120 includes a flexible film 124. When the screen component 110 is adjusted for interpupillary distance or moved to other positions, the flexible film 124 can adaptively deform, reducing the possibility of leakage of the working fluid 160 in the heat dissipation component 120. Furthermore, a heat conductor 126 is provided on the flexible film 124. One side of the heat conductor 126 is connected to the screen component 110, and the other side is connected to the flexible film 124. The heat generated by the screen component 110 is conducted to the cavity 1222 through the heat conductor 126, and the working fluid 160 is injected into the cavity 1222.

[0048] Optionally, the size of the first mounting hole 1224 can be determined based on the area of ​​the screen assembly 110 and the travel distance of the screen assembly 110 for interpupillary distance adjustment, as long as it meets the movement requirements of the screen assembly 110.

[0049] The flexible membrane 124 typically possesses low modulus, high ductility, high tear strength, and good airtightness. It is used to connect the body 122 and the heat-conducting component 126, enabling the movement of the heat-conducting component 126, adaptive deformation, and leak prevention. The flexible membrane 124 can be made of rubber (nitrile rubber or neoprene rubber, etc.), silicone, or latex. In other embodiments of this application, the flexible membrane 124 can also be made of other materials, as long as it possesses a certain degree of elasticity and heat resistance. The bonding process between the flexible membrane 124 and the body 122 and the heat-conducting component 126 is only required to achieve a tight fit, preventing the flexible membrane 124 from detaching, cracking, or leaking during the movement of the heat-conducting component 126.

[0050] The heat-conducting component 126 is used to connect the screen assembly 110 and the flexible film 124, and is the core pathway for heat transfer from the screen assembly 110 to the working fluid 160.

[0051] The working fluid 160 typically has a large specific heat capacity, high latent heat, and high thermal conductivity. It can be water, alcohol-based solutions (such as ethanol), acetone, or fluorocarbons, or it can be the above working fluid 160 filled with a certain mass percentage of micro or nano-scale thermally conductive particles. Nano-scale thermally conductive particles include, but are not limited to: aluminum nitride (AlN), silicon nitride (Si3N4), silicon carbide (SiC), and polycrystalline diamond (PCD).

[0052] As one possible implementation, the periphery and the middle portion of the flexible film 124 are connected to the inner surface of the body 122 and the bottom surface of the heat-conducting component 126 by processes such as adhesive bonding and / or hot pressing. This achieves the connection between the flexible film 124 and the body 122 and the heat-conducting component 126, reducing the possibility of leakage of the working fluid 160 during the movement of the heat-conducting component 126. On the other hand, it enables natural dynamic heat dissipation during the positional change of the screen assembly 110 during the interpupillary distance adjustment process.

[0053] The screen assembly 110 can be a liquid crystal on silicon (LCOS) assembly, a liquid crystal display (LCD) assembly, a digital micromirror device (DMD) assembly, a digital light processing (DLP) assembly, an organic light-emitting diode (OLED) assembly, or a micro light-emitting diode (Micro LED) assembly, etc. Optionally, the screen assembly 110 can be an organic light-emitting diode (OLED) assembly.

[0054] As shown in Figures 1, 3 and 10, in one possible implementation, the smart glasses 100 further includes: a frame 130; a slider assembly 140 disposed on the frame 130, the main body 122 and the slider assembly 140 being connected, and a heat dissipation assembly 120 being movable relative to the frame 130.

[0055] Specifically, the smart glasses 100 also includes a frame 130 and a slider assembly 140. The screen assembly 110 can be disposed on the frame 130, the slider assembly 140 is disposed on the frame 130, and the heat dissipation assembly 120 is connected to the slider assembly 140, thereby allowing the heat dissipation assembly 120 to move relative to the frame 130, so that the heat dissipation assembly 120 can better adapt to the interpupillary distance adjustment of the smart glasses 100 and reduce the possibility of damage to the heat dissipation assembly 120.

[0056] As shown in Figures 3, 4 and 6, the main body 122 also includes a support leg 1232, which is connected to the slide rod assembly 140. The support leg 1232 can be an independent structural component or it can be designed as an integral part of the main body 122. The main body 122 can be fixed to the slide rod assembly 140 by welding, screw fastening, gluing or other methods to ensure that the screen assembly 110 and the heat dissipation assembly 120 remain relatively stationary during the movement of the screen assembly 110.

[0057] The body 122 and the legs 1232 typically have high strength and can be made of metals (stainless steel, copper alloys, or titanium alloys, etc.), ceramics, plastics, metal-plastic composites, or metal-ceramic composites. Ceramic materials include, but are not limited to: aluminum nitride (AlN), silicon nitride (Si3N4), silicon carbide (SiC), and polycrystalline diamond (PCD).

[0058] As shown in Figures 3 and 10, in one possible implementation, the slide rod assembly 140 includes a slide rod bracket 144 and a slide rod 142. The slide rod bracket 144 is connected to the frame 130, and the slide rod 142 is disposed on the slide rod bracket 144. The slide rod bracket 144 and the frame 130 can be an integral structure.

[0059] The slide rod 142 and the slide rod bracket 144 can be slidably connected, and the slide rod 142 and the body 122 can be fixedly connected; or, the slide rod 142 and the body 122 can be slidably connected, and the slide rod 142 and the slide rod bracket 144 can be fixedly connected.

[0060] The slider 142 can also be connected to the lens assembly 150, the screen 114 and the protective component 112, so that the screen assembly 110, the lens assembly 150 and the heat dissipation assembly 120 can move synchronously.

[0061] As shown in Figures 3 and 10, in one possible implementation, the slide rod assembly 140 includes at least two slide rods 142, which are disposed on the frame 130 and located on opposite sides of the heat dissipation assembly 120, and the heat dissipation assembly 120 is connected to the at least two slide rods 142.

[0062] Specifically, the slider assembly 140 includes at least two sliders 142, all of which are disposed on the frame 130. The at least two sliders 142 are located on opposite sides of the heat dissipation assembly 120. The heat dissipation assembly 120 is connected to all the sliders 142, meaning that the sliders 142 provide support for the heat dissipation assembly 120 in multiple directions, thereby making the movement of the heat dissipation assembly 120 more stable and ensuring the reliability of the contact between the heat dissipation assembly 120 and the screen assembly 110.

[0063] As shown in Figures 5, 6 and 11, in one possible implementation, the screen assembly 110 includes: a protective member 112, which is in contact with the heat dissipation assembly 120; and a screen 114 disposed on the protective member 112.

[0064] Specifically, the screen assembly 110 includes a protective member 112 and a screen 114. The screen assembly 110 is disposed on the protective member 112, which can protect the screen assembly 110 and reduce the possibility of damage to the screen assembly 110. The protective member 112 is in contact with the heat dissipation assembly 120, thereby transferring the heat emitted by the screen 114 to the heat dissipation assembly 120.

[0065] As one possible implementation, as shown in FIG8, the edge of the protective member 112 has a first mounting portion 1122, and as shown in FIG6 and FIG7, the edge of the heat-conducting member 126 has a second mounting portion 1262. The first mounting portion 1122 and the second mounting portion 1262 are fixedly connected by screws.

[0066] Specifically, the edge of the protective component 112 has a first mounting portion 1122, and the edge of the heat-conducting component 126 has a second mounting portion 1262. Screws pass through the first mounting portion 1122 and the second mounting portion 1262 to fix the protective component 112 and the heat-conducting component 126, thereby improving the reliability of the contact between the protective component 112 and the heat-conducting component 126 and ensuring the heat dissipation effect of the screen assembly 110.

[0067] That is, the connection between the heat-conducting component 126 and the protective component 112 can be made by screws.

[0068] As one possible implementation, as shown in FIG14, a magnetic element 1124 is provided on the protective element 112; the heat-conducting element 126 is made of ferromagnetic material, and the magnetic element 1124 and the heat-conducting element 126 are attracted to each other; or as shown in FIG15, a magnetic attracting element 1264 is provided on the heat-conducting element 126, and the magnetic element 1124 and the magnetic attracting element 1264 are attracted to each other.

[0069] Specifically, the protective component 112 is provided with a magnetic component 1124, and the heat-conducting component 126 is made of ferromagnetic material. The magnetic component 1124 and the heat-conducting component 126 attract each other, thereby realizing the magnetic fixation of the protective component 112 and the heat-conducting component 126, improving the reliability of the contact between the protective component 112 and the heat-conducting component 126, and ensuring the heat dissipation effect of the screen assembly 110.

[0070] Alternatively, a magnetic component 1124 may be provided on the protective component 112, and a magnetic suction component 1264 may be provided on the heat-conducting component 126. The magnetic component 1124 and the magnetic suction component 1264 are attracted to each other, thereby achieving magnetic fixation of the protective component 112 and the heat-conducting component 126, improving the reliability of the contact between the protective component 112 and the heat-conducting component 126, and ensuring the heat dissipation effect on the screen assembly 110.

[0071] That is, magnetic elements 1124 are provided around the protective element 112, and the magnetic field is used to achieve the attraction between the heat-conducting element 126 and the protective element 112.

[0072] The magnetic component 1124 can be a ring-shaped structure located around the periphery of the protective component 112, or the magnetic component 1124 can be multiple block-shaped structures located at different positions on the protective component 112. Similarly, the magnetic attracting component 1264 can be a ring-shaped structure located around the periphery of the heat-conducting component 126, or the magnetic attracting component 1264 can be multiple block-shaped structures located at different positions on the heat-conducting component 126.

[0073] The heat-conducting component 126 typically possesses high strength and thermal conductivity. Its material can be a ferromagnetic metal (iron, nickel, or cobalt) or a composite material of ferromagnetic metal and ceramic. Alternatively, parts of the heat-conducting component 126 may be made of non-ferromagnetic metals (titanium alloys, copper alloys, or aluminum alloys, etc.), ceramic, or a composite material of metal and ceramic. A magnetic absorbing component 1264 may be locally provided in the heat-conducting component 126. The magnetic absorbing component 1264 can be made of a ferromagnetic metal (iron, nickel, or cobalt) or ferromagnetic oxide. Ceramic materials include, but are not limited to: aluminum nitride (AlN), silicon nitride (Si3N4), silicon carbide (SiC), and polycrystalline diamond (PCD).

[0074] As shown in Figures 7 and 13, in one possible implementation, the flexible membrane 124 has a second mounting hole 1242, and the heat-conducting element 126 is located in the second mounting hole 1242.

[0075] Specifically, the flexible film 124 has a second mounting hole 1242, and the heat-conducting element 126 is located at the second mounting hole 1242, so that the heat-conducting element 126 directly contacts the working fluid 160 in the cavity 1222, thereby improving the heat conduction effect between the heat-conducting element 126 and the working fluid 160 and improving the heat dissipation effect of the screen assembly 110.

[0076] That is, part of the heat-conducting element 126 is in contact with the flexible membrane 124, and part of the heat-conducting element 126 is in direct contact with the working fluid 160.

[0077] As shown in Figures 16, 17, 18 and 19, in one possible implementation, the heat-conducting element 126 has a protruding structure 1266 on the side facing the cavity 1222.

[0078] Specifically, the heat-conducting component 126 has a protruding structure 1266 on the side facing the cavity 1222. The protruding structure 1266 can increase the contact area between the heat-conducting component 126 and the working fluid 160 in the cavity 1222, and can promote the phase change of the working fluid 160, thereby improving the heat dissipation effect on the screen assembly 110.

[0079] The protrusion structure 1266 on the heat-conducting component 126 can be a boss, a powder layer, or a mesh structure, which can stimulate the heat exchange mode of the working fluid 160 near the protrusion structure 1266 to evolve from natural convection to nucleation boiling phase, thereby improving the heat dissipation effect.

[0080] That is, the heat exchange effect between the heat-conducting component 126 and the working fluid 160 is increased by the protruding structure 1266. The contact surface between the heat-conducting component 126 and the working fluid 160 can be microstructured to form the protruding structure 1266. The protruding structure 1266 can be small protrusions arranged in an array according to a certain pattern, as shown in Figure 16. The cross-section of the protrusion can be triangular, as shown in Figure 17. The cross-section of the protrusion can be circular. Of course, the cross-section of the protrusion can also be other shapes. In addition, as shown in Figure 18, the protruding structure 1266 can also be a mesh structure of a certain thickness, as shown in Figure 19. The protruding structure 1266 can also be sintered powder of a certain thickness. Of course, the protrusion can also be other structures.

[0081] The raised structure 1266 can be made of metal (stainless steel, copper alloy, aluminum alloy or titanium alloy, etc.), ceramic or metal-ceramic composite material, etc. Ceramic includes, but is not limited to: aluminum nitride (AlN), silicon nitride (Si3N4), silicon carbide (SiC), and polycrystalline diamond (PCD).

[0082] As shown in Figures 3, 5 and 11, in one possible implementation, there are two screen assemblies 110, two first mounting holes 1224, two flexible films 124 and two heat-conducting elements 126, one cavity 1222, and one heat-conducting element 126 in contact with one screen assembly 110.

[0083] Specifically, there are two screen components 110, corresponding to the human eye. There are two first mounting holes 1224, two flexible films 124, and two heat conductors 126. One first mounting hole 1224, one flexible film 124, and one heat conductor 126 correspond to one screen component 110. There is one cavity 1222, which increases the volume of the cavity 1222 and the amount of working fluid 160 in the cavity 1222. Furthermore, this arrangement connects the heat transfer channels of the two screen components 110, improves the heat dissipation environment of a single screen component 110, and enhances the heat dissipation effect of the screen component 110.

[0084] The working fluid 160 inside the heat dissipation component 120 connects the heat transfer channels of the two screen components 110. On the one hand, it uses the principle of heat conduction to increase the contact area between the screen component 110 and the heat conductor 126, thereby improving the heat dissipation effect of the screen component 110. On the other hand, it uses the phase change or natural convection caused by the heating of the working fluid 160 to further enhance the heat dissipation effect of the screen component 110. That is, the heat generated by the screen 114 is conducted to the working fluid 160 through the protective component 112 and the heat conductor 126. By utilizing the large filling volume and local phase change of the working fluid 160, rapid heat dissipation of a single screen 114 can be achieved.

[0085] As shown in Figures 2, 4, 5, 7, 11 and 13, in one possible implementation, the body 122 includes: a first body 1226; a second body 1228 connected to the first body 1226 to form a cavity 1222, and a first mounting hole 1224 located in the second body 1228; wherein, one of the first body 1226 and the second body 1228 has a working fluid injection port 1230.

[0086] Specifically, the body 122 also includes a first body 1226 and a second body 1228, which are connected to form a cavity 1222, thereby reducing the manufacturing difficulty of the body 122. A first mounting hole 1224 is located in the second body 1228. One of the first body 1226 and the second body 1228 has a working fluid injection port 1230, which is used to inject working fluid 160.

[0087] That is, the heat dissipation component 120 includes a body 122, a flexible membrane 124, and a heat-conducting component 126. The body 122 includes a first body 1226 and a second body. The first body 1226 or the second body 1228 has a working fluid injection port 1230. The first body 1226 and the second body 1228 can be sealed together by welding or other means. The working fluid injection port 1230 is provided on the periphery of the first body 1226 or the second body 1228 for filling the cavity 1222 with working fluid 160 or for evacuating the cavity 1222. In this way, a specific low vacuum degree can be achieved in the cavity 1222 with the help of a vacuuming device, so that the working fluid 160 can undergo a phase change at room temperature, thereby enhancing the heat dissipation effect.

[0088] To enhance the heat dissipation effect inside the cavity 1222, its first body 1226 can be fixed to the frame 130 with adhesive 170.

[0089] Furthermore, a first mounting hole 1224 is provided on the second body 1228 at a position corresponding to the screen assembly 110 and its travel. That is, the first mounting hole 1224 corresponds to the orthographic projection of the screen assembly 110 and its travel onto the second body 1228, and a flexible film 124 is provided at the first mounting hole 1224. The first mounting hole 1224 corresponds to the maximum range of movement of the screen assembly 110 in its direction of movement.

[0090] The first body 1226 and the second body 1228 are made of materials with high strength and thermal conductivity, such as metals (stainless steel, copper alloys, aluminum alloys, or titanium alloys), ceramics, metal-plastic composites, or metal-ceramic composites. This prevents deformation during assembly or drops, which could weaken the heat dissipation characteristics of the cavity 1222. Furthermore, the high thermal conductivity helps reduce the temperature difference of the working fluid 160, enhancing its heat exchange effect and aiding in the heat dissipation of the cavity 1222. In other embodiments of this application, the first body 1226 and the second body 1228 can also be made of other materials, as long as they meet the purpose of enhanced heat dissipation and the process only requires a combined sealing principle. Ceramic materials include, but are not limited to, aluminum nitride (AlN), silicon nitride (Si3N4), silicon carbide (SiC), and polycrystalline diamond (PCD).

[0091] As shown in Figures 2, 6 and 12, the working fluid injection port 1230 can be part of the first body 1226 and / or the second body 1228, or it can be an independent structural component that is connected to the first body 1226 and / or the second body 1228 by welding or other processes. The material of the working fluid injection port 1230 can be the same as or different from that of the first body 1226 and / or the second body 1228.

[0092] In one possible implementation, the frame 130 includes a frame and a decorative element, with the screen assembly 110 and the heat dissipation assembly 120 disposed on the frame, and the decorative element disposed on the frame and covering the heat dissipation assembly 120.

[0093] As shown in Figures 1, 5 and 9, in one possible implementation, the smart glasses 100 also includes a lens group 150, with the lens group 150 and the screen assembly 110 correspondingly arranged.

[0094] In this application, the heat dissipation component 120 has a sealed cavity 1222. Utilizing the adaptive deformation characteristics of the flexible membrane 124 under stress, the heat conductor 126 and the main body 122 are sealed and dynamically and naturally dissipated during the interpupillary distance adjustment process. The connection between the heat conductor 126 and the screen assembly 110 is achieved through the fixing structure of the heat conductor 126 and the screen assembly 110. Utilizing the special protrusion structure 1266 on the contact surface between the heat conductor 126 and the working fluid 160, the working fluid 160 near the protrusion structure 1266 is stimulated to undergo a phase change, thereby enhancing the heat dissipation effect and further strengthening the heat dissipation effect on the screen assembly 110. Utilizing the working fluid 160, the heat transfer path of the two screen assemblies 110 is connected, increasing the heat transfer area of ​​a single screen assembly 110 while assisting the local working fluid 160 of the heat conductor 126 to undergo a phase change, thereby achieving large-area and efficient heat dissipation within the cavity 1222.
