[0045] This embodiment discloses a smart glasses, such as AR glasses. Referring to Figure 1 and Figure 2 , it includes a temple 100, a frame 200, a lens 300, a PCB board 500, a heat conducting member 400, etc.

[0046] The temple 100 is rotatably connected to the frame 200. The temple 100 is unfolded relative to the frame 200 for the user to wear, and the temple 100 is folded relative to the frame 200 for easy storage and carrying.

[0047] A first installation cavity 110 is formed inside the temple 100, and the PCB board 500 is disposed inside the first installation cavity 110.

[0048] The frame 200 encloses an installation opening for installing the lens 300, and the lens 300 is disposed inside the installation opening.

[0049] When the smart glasses work, the PCB board 500 generates heat, and it is necessary to cool the PCB board 500 in time to ensure the continuous and reliable operation of the smart glasses. At the same time, when the smart glasses are switched between two usage spaces with a large temperature difference, due to the existence of the temperature difference, fog is likely to form on the lens 300, affecting the visual quality of the smart glasses.

[0050] Based on this, this embodiment proposes a structure that uses the heat generated by the PCB board 500 to prevent fogging on the lens 300.

[0051] Specifically, a second installation cavity 210 is formed inside the frame 200. The second installation cavity 210 is located below the installation opening, that is, the second installation cavity 210 is located below the lens 300.

[0052] A plurality of cavities 310 arranged at intervals are provided inside the lens 300. Each cavity 310 extends along the vertical height direction of the lens 300, and a heat conducting medium is filled inside the cavity 310.

[0053] The heat-conducting member 400 extends and is disposed in the first installation cavity 110 and the second installation cavity 210. One end of the heat-conducting member 400 is connected to the PCB board 500, and the other end extends along the second installation cavity 210. The heat-conducting member 400 is used to conduct the heat of the PCB board 500 into the second installation cavity 210.

[0054] When the smart glasses are working, the PCB board 500 generates heat. The heat-conducting member 400 conducts this heat into the second installation cavity 210. Since the second installation cavity 210 is located on the lower side of the lens 300, it is equivalent to conducting the heat to the lower side of the lens 300, and there is no heat-conducting component on the upper side of the lens 300. In this way, the temperature of the lower side of the lens 300 is higher than the temperature of the upper side of the lens 300, a temperature difference is generated between the upper and lower sides of the lens 300, the lower side of the lens 300 is hot and the upper side is cold, and the temperature difference causes the heat-conducting medium to flow upward from the lower side to the upper side in the cavity 310. During the process of the heat-conducting medium flowing in the cavity 310, the lens 300 is heated, so as to achieve the purpose of preventing the lens 300 from fogging and quickly defogging the lens 300.

[0055] At the same time, the PCB board 500 can be timely cooled, so as to avoid the temperature of the PCB board 500 being too high and ensure the continuous and reliable operation of the smart glasses.

[0056] In some embodiments, one end of the heat-conducting member 400 is connected to the heat source component on the PCB board 500. The heat source component mainly refers to chips, etc. The chips generate a large amount of heat. By timely cooling the heat source component through the heat-conducting member 400, the heat dissipation and cooling of the PCB board 500 can be achieved.

[0057] In some embodiments, the inner diameter of the cavity 310 is at the micron level. The micron-level cavity 310 is processed and formed inside the lens 300 by using process technologies such as etching. Since the inner diameter of the cavity 310 is very small, it has no influence on the light transmission of the lens 300 and does not affect the visual effect of the lens 300.

[0058] Figure 2 In, the dotted line on the lens 300 represents the cavity 310, which is only a simple illustration and does not represent information such as the number and inner diameter of the cavity 310.

[0059] In some embodiments, the cavity 310 penetrates through the lens 300 up and down, and the heat-conducting medium filled in the cavity 310 is air.

[0060] The heat-conducting member 400 conducts the heat generated by the PCB board 500 into the second installation cavity 210. The temperature in the second installation cavity 210 increases, which makes the temperature of the frame 200 on the lower side of the lens 300 increase. The lower side of the lens 300 is hot and the upper side is cold, which makes the air in the cavity 310 flow upward along the cavity 310. The lens 300 is heated, so as to achieve the purpose of preventing the lens 300 from fogging or quickly defogging the lens 300.

[0061] On this basis, a hollow hole (not shown) is provided on the top wall of the second installation cavity 210 to connect the second installation cavity 210 with the installation port. The lower side of the lens 300 abuts against the top wall of the second installation cavity 210, and the cavity 310 is connected to the second installation cavity 210.

[0062] After the heat conducting member 400 conducts the heat of the PCB board 500 into the second installation cavity 210, the setting of the hollow hole enables the cavity 310 in the lens 300 to be connected to the second installation cavity 210, and the heat in the second installation cavity 210 can be quickly conducted into the cavity 310, thereby increasing the air temperature in the cavity 310, so as to achieve the purpose of quickly heating the lens 300.

[0063] In some other embodiments, both the upper and lower ends of the cavity 310 are blocked, and the heat conducting medium filled in the cavity 310 is a metal conductor. The metal conductor can be nano silver, indium tin oxide, etc.

[0064] After the heat conducting member 400 conducts the heat of the PCB board 500 into the second installation cavity 210, the temperature in the second installation cavity 210 increases, causing the temperature of the frame 200 on the lower side of the lens 300 to increase. The lower part of the lens 300 is hot and the upper part is cold. The heat is conducted from the lower side to the upper side of the lens 300 through the metal conductor, and the lens 300 is heated, so as to achieve the purpose of preventing the lens 300 from fogging or quickly defogging the lens 300.

[0065] In some embodiments, a plurality of cavities 310 are arranged at intervals along the transverse width direction of the lens 300, and the bottom of each cavity 310 faces the second installation cavity 210.

[0066] The bottom of each cavity 310 is set to face the second installation cavity 210 to ensure that the temperature of the bottom side of each cavity 310 is higher than that of its top side, making the temperature in the cavity 310 hot at the bottom and cold at the top. The heat conducting medium in the cavity 310 flows from bottom to top, so as to uniformly heat the lens 300.

[0067] On this basis, the heat conducting member 400 is arranged to extend along the second installation cavity 210, so that the bottom side of each cavity 310 faces the heat conducting member 400, and each cavity 310 can be heated reliably and uniformly, improving the heat conduction efficiency, and further improving the effect of preventing fogging and quickly defogging.

[0068] In some embodiments, two installation ports are provided on the frame 200. The nose pad setting position 220 is between the two installation ports. A temple mounting position 230 for connecting with the temple 100 is provided on the frame 200. One end of the temple 100 is rotatably connected to the temple mounting position 230, and the second installation cavity 210 extends between the nose pad setting position 220 and the temple mounting position 230.

[0069] An installation cavity is also provided inside the temple mounting position 230, denoted as the third installation cavity (not shown). The first installation cavity 110, the third installation cavity, and the second installation cavity 210 are connected, and the heat conducting member 400 extends and is disposed inside the first installation cavity 110, the third installation cavity, and the second installation cavity 210.

[0070] The third installation cavity is directly opposite and connected to the first installation cavity 110. After the heat conducting member 400 is led out from the first installation cavity 110, it directly extends into the third installation cavity and then extends into the second installation cavity 210 from the third installation cavity.

[0071] As can be seen from the figure, the nose pad setting position 220 and the temple mounting position 230 are at approximately the same horizontal height position. Based on the approximate elliptical shape of the lens 300, the second installation cavity 210 is extended to a position below the middle of the lens 300, which is beneficial to maximizing the number of the set cavities 310 and helps to improve the heating efficiency of the lens 300.

[0072] On this basis, the heat conducting member 400 includes a first section 410 of the heat conducting member and a second section 420 of the heat conducting member.

[0073] One end of the first section 410 of the heat conducting member is connected to the PCB board 500, the other end of the first section 410 of the heat conducting member is connected to the second section 420 of the heat conducting member, and the first section 410 of the heat conducting member extends and is disposed inside the first installation cavity 110 and the temple mounting position 230. The second section 420 of the heat conducting member extends and is disposed inside the second installation cavity 210.

[0074] Since the first installation cavity 110 inside the temple 100 and the third installation cavity inside the temple mounting position 230 are directly opposite and connected front and back, the first section 410 of the heat conducting member is provided to extend inside the first installation cavity 110 and the third installation cavity. The second installation cavity 210 extends along the lower arc contour of the lens 300, and the second section 420 of the heat conducting member is extended inside the second installation cavity 210. The two-section structure of the heat conducting member 400 facilitates the installation of the heat conducting member 400.

[0075] On this basis, a corrugated pipe section (not shown) is provided on the first section 410 of the heat conducting member, and the corrugated pipe section is located at the rotational connection position between the temple 100 and the temple mounting position 230.

[0076] The corrugated pipe section helps to improve the softness and anti-bending life of the first section 410 of the heat conducting member. The tensile stress received when the corrugated pipe section is bent is small, avoiding the tensile stress on the corrugated pipe section when the temple 100 is bent, thereby effectively prolonging the life of the heat conducting member 400.

[0077] In some embodiments, heat conducting silicone is provided on the contact surfaces of the heat conducting member 400 with the PCB board 500 and the second installation cavity 210 to improve the heat conduction efficiency, which helps to improve the heat dissipation and cooling effect of the PCB board 500 and the heating efficiency of the lens 300.

[0078] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0079] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this utility model should be included in the scope of protection of the present utility model.
