Increasing the projection brightness of the optical engine module also increases its power consumption, leading to more noticeable heat generation. Furthermore, due to the stringent requirements for lightweight design in smart glasses, passive cooling methods that significantly increase weight, such as fans, cannot be used.

[0004] Therefore, a new technical solution is needed to improve the heat dissipation capability of smart glasses. Summary of the Invention

[0043] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0045] Reference Figures 1-9 As shown, according to one embodiment of this application, a smart head-mounted device 1 is provided. The smart head-mounted device 1 includes a light source 11, an optical engine module 12, and a housing 13. The optical engine module 12 is disposed within the housing 13. The smart head-mounted device 1 also includes a first support 14, a second support 15, and a first heat-conducting component 16. The first support 14 is disposed within the housing 13 and is used to mount optical elements. The light source 11 is disposed on the side of the first support 14 away from the optical engine module 12.

[0046] The second bracket 15 is disposed inside the housing 13. The second bracket 15 is made of heat dissipation material and is located on the side of the light source 11 away from the first bracket 14. A portion of the first heat-conducting element 16 is attached to the light source 11, and another portion of the first heat-conducting element 16 is attached to the second bracket 15. The heat emitted by the light source 11 is transferred to the second bracket 15 via the first heat-conducting element 16.

[0047] In the smart head-mounted device 1 provided in this application embodiment, firstly, the light source 11 serves as a light-emitting element and is also the largest heat source in the entire smart head-mounted device; the smart head-mounted device 1 provided in this application embodiment separates the light source 11 from the optomechanical module 12, and the light source 11 is located on the side of the first bracket 14 away from the optomechanical module 12; in this way, the heat emitted by the optomechanical module 12 and the heat emitted by the light source 11 are separated, avoiding the phenomenon of local overheating caused by heat concentration in the smart head-mounted device 1.

[0048] Furthermore, in the smart head-mounted device 1 provided in this application embodiment, a first heat-conducting element 16 for heat dissipation is provided. Specifically, a portion of the first heat-conducting element 16 is attached to the light source 11, and another portion of the first heat-conducting element 16 is attached to the second support 15. Thus, the first heat-conducting element 16 can transfer the heat emitted by the light source 11 to the second support 15. Since the second support 15 is made of a heat-dissipating material, the second support 15 can evenly disperse the heat transferred from the first heat-conducting element 16, avoiding heat concentration. Optionally, the second support 15 is made of Mg-Al alloy, which has strong heat dissipation capacity, thereby ensuring that the second support 15 can effectively disperse the heat emitted by the light source 11 to the entire second support 15 to avoid heat concentration.

[0049] Reference Figure 5 As shown, in one embodiment, the first heat-conducting element 16 includes a first heat-conducting sheet 161, a second heat-conducting sheet 162, and a connecting piece 163. The first heat-conducting sheet 161 and the second heat-conducting sheet 162 are opposite to each other and spaced apart. One end of the first heat-conducting sheet 161 and one end of the second heat-conducting sheet 162 are both connected to the connecting piece 163.

[0050] The side of the first heat-conducting sheet 161 facing away from the second heat-conducting sheet 162 is attached to the light source 11; the side of the second heat-conducting sheet 162 close to the first heat-conducting sheet 161 is attached to the second bracket 15.

[0051] In this specific example, the first heat-conducting component 16 can be a sheet-like structure as a whole. After bending, the sheet-like structure forms the first heat-conducting sheet 161, the second heat-conducting sheet 162, and the connecting sheet 163. That is, the first heat-conducting sheet 161, the second heat-conducting sheet 162, and the connecting sheet 163 are integrally formed, which makes the forming method of the first heat-conducting component 16 relatively simple.

[0052] When setting the first heat-conducting element 16, the side of the first heat-conducting sheet 161 facing away from the second heat-conducting sheet 162 is attached to the light source 11, and the side of the second heat-conducting sheet 162 close to the first heat-conducting sheet 161 is attached to the second bracket 15. In this way, the heat emitted by the light source 11 is transferred to the second heat-conducting sheet 162 through the first heat-conducting sheet 161 and the connecting piece 163, and then transferred to the second bracket 15 by the second heat-conducting sheet 162.

[0053] In one embodiment, the side of the first heat-conducting sheet 161 near the second heat-conducting sheet 162 is attached to the second bracket 15.

[0054] In this specific example, the thickness of the second support 15 matches the distance between the first heat-conducting sheet 161 and the second heat-conducting sheet 162; that is, the first heat-conducting sheet 161 and the second heat-conducting sheet 162 sandwich the second support 15 in the middle, and both the first heat-conducting sheet 161 and the second heat-conducting sheet 162 are fitted to the second support 15, which can improve the effect of the first heat-conducting element 16 in transferring heat to the second support 15.

[0055] In one embodiment, the first heat-conducting element 16 is made of graphite, aluminum foil, or copper foil.

[0056] In this specific example, the first heat-conducting element 16 can be made of graphite sheet, aluminum foil, or copper foil. Graphite sheet is lightweight, has high thermal conductivity, and is highly ductile; it can be easily bent according to actual usage needs, and provides good thermal conductivity without significantly increasing weight.

[0057] In one embodiment, the first bracket 14 is made of a heat-dissipating material.

[0058] In this specific example, the first bracket 14 is also made of Mg-Al alloy, which provides good support and fixation for optical elements while also having good heat dissipation function.

[0059] Reference Figure 6 As shown, in one embodiment, the first support 14 is an annular structure with a first hollow cavity 140, and a positioning groove 141 is provided on one side of the first support 14 around the first hollow cavity 140.

[0060] The optical element is an optical waveguide module 17. The edge of the optical waveguide module 17 is fixedly installed in the positioning groove 141, and the first bracket 14 has an avoidance through hole 1400 in the positioning groove 141.

[0061] The optical engine module 12 includes an optical engine body 121, which is connected to the side of the first bracket 14 away from the optical waveguide module 17, and the projection end of the optical engine body 121 is connected to the optical waveguide module 17 through the clearance through hole 1400.

[0062] Furthermore, referring to Figure 7 As shown, the second support 15 is an annular structure with a second hollow cavity 150, which is correspondingly arranged with the optical waveguide module 17.

[0063] In this specific example, the optical waveguide module 17 is a guiding structure for transmitting optical frequency electromagnetic waves, made of an optically transparent medium; it is a medium device that guides the propagation of light waves therein. The optical waveguide module 17 is configured to correspond to both the light source 11 and the optomechanical module 12.

[0064] Specifically, the optical engine body 121 is connected to the side of the first support 14 away from the optical waveguide module 17, and the projection end of the optical engine body 121 is connected to the optical waveguide module 17 through the clearance through-hole 1400; while the light source 11 is connected to the side of the first support 14 where the optical waveguide module 17 is located through the flexible circuit board 110, and the position of the light source 11 corresponds to the position of the clearance through-hole 1400. After the optical engine module 12 completes the imaging process, the optical waveguide module 17 couples the light emitted by the light source 11 into its own glass substrate, and transmits the light to the front of the wearer's eyes through the principle of "total internal reflection" before releasing it.

[0065] Since the first support 14 is also made of Mg-Al alloy, it can effectively disperse the heat emitted by the light source 11 throughout the entire first support 14 to avoid heat concentration. Furthermore, both the first support 14 and the second support 15 are annular structures, and both can disperse heat throughout their annular structures, thereby achieving a good heat dissipation effect.

[0066] Optionally, the optical waveguide module 17 can be connected to the first bracket 14 by adhesive bonding; wherein, the positioning groove 141 can facilitate the positioning and installation of the optical waveguide module 17 on the first bracket 14 and ensure the stability of the installation.

[0067] Optionally, the second bracket 15 is detachably connected to the first bracket 14; for example, the second bracket 15 and the first bracket 14 are detachably connected by fasteners such as bolts. In addition, the surface of the second bracket 15 facing the first bracket 14 is provided with a clearance groove 151 for avoiding the light source 11.

[0068] Reference Figure 8 As shown, in one embodiment, the optical engine module 12 further includes a display device 122 connected to the optical engine body 121;

[0069] The smart head-mounted device also includes a second heat-conducting component 18; a portion of the second heat-conducting component 18 is attached to the display device 122, and another portion of the second heat-conducting component 18 is connected to the first bracket 14.

[0070] In this specific example, since the display device 122 is also an important heat-generating element, a second heat-conducting element 18 is provided in the smart head-mounted device to transfer the heat emitted by the display device 122 to the first support 14 and then to the second support 15; both the first support 14 and the second support 15 can play the role of dispersing the heat emitted by the display device 122.

[0071] Optionally, the display device 122 can be, for example, an LCOS. The main function of the LCOS is to control the switching of light from the light source 11 to transform the light path and form an image through the switching of the liquid crystal layer. Of course, the display device 122 can also be other types of display devices.

[0073] In this specific example, the third heat-conducting sheet 181 may include a bent portion 1810; wherein, the structure of the third heat-conducting sheet 181 on one side of the bent portion 1810 is fitted and connected to the display device 122, and the structure of the third heat-conducting sheet 181 on the other side of the bent portion 1810 is fitted and connected to the optical engine body 121. Multiple fourth heat-conducting sheets 182 may be provided, for example, two; the side of the fourth heat-conducting sheet 182 is fitted and connected to the optical engine body 121, and the end of the fourth heat-conducting sheet 182 is connected to the first bracket 14.

[0074] Optionally, the third heat-conducting sheet 181 and the fourth heat-conducting sheet 182 are integrally formed.

[0075] In one embodiment, the second heat-conducting element 18 is made of graphite, aluminum foil, or copper foil.

[0076] In this specific example, the second heat-conducting element 18 can be made of graphite sheet, aluminum foil, or copper foil. Graphite sheet is lightweight, has high thermal conductivity, and is highly ductile; it can be easily bent according to actual usage needs, and provides good thermal conductivity without significantly increasing weight.

[0077] Reference Figure 1 , Figure 2 As shown, in one embodiment, the housing 13 includes a first housing 131 and a second housing 132 that are mated together.
