[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention.

[0058] A snow goggles, comprising:

[0059] external mirror body,

[0060] An inner mirror body, arranged opposite to the outer mirror body;

[0061] A dimming film is arranged between the outer mirror body and the inner mirror body;

[0062] Wherein, a first gap is formed between the dimming film and the inner mirror body.

[0063] In the above structure, a gap is set between the dimming film and the inner mirror body to separate the dimming film and the inner mirror body, so as to prevent the inner mirror body in direct contact with the human body from transmitting temperature to the dimming film, resulting in a large temperature difference between the side of the dimming film close to the outer mirror body and the side of the dimming film close to the inner mirror body, thereby balancing the temperature difference of the dimming film and improving the control accuracy of the dimming film.

[0064] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0065] Please refer to Figure 1-Figure 8 An embodiment of the present invention provides a snow goggle 100, comprising: an outer lens body 10, an inner lens body 20, a dimming film 30 and a gap.

[0066] Specifically, in order to balance the temperature difference of the working environment of the dimming film 30 , the dimming film 30 is arranged between the outer body 10 and the inner body 20 by arranging the inner body 20 opposite to the outer body 10 , and a first gap 40 is formed between the dimming film 30 and the inner body 20 . Among them, one side of the dimming film 30 is connected to the outer mirror body 10, and the other side is spaced apart from the inner mirror body 20 by a first gap 40. Since the dimming film 30 is connected to the outer mirror body 10 through a solid, the dimming film 30 and the inner mirror body 20 are equivalent to being connected through air. In a closed state, the thermal conductivity of air is 0.023W / m·k, and the thermal conductivity of most entities is much greater than that of air. In this embodiment, the part where the outer mirror body 10 and the dimming film 30 meet is made of glass material, and the thermal conductivity of glass is 1.03W / m·k, so that the overall temperature of the dimming film 30 is close to the overall temperature of the outer mirror body 10, thereby preventing the inner mirror body 20 in direct contact with the human body from conducting the temperature to the dimming film 30, resulting in a large temperature difference between the side of the dimming film 30 close to the outer mirror body 10 and the side of the dimming film 30 close to the inner mirror body 20, thereby balancing the temperature difference of the dimming film 30 and improving the control accuracy of the dimming film 30.

[0067] In one embodiment, the dimming film 30 includes a liquid crystal layer 31 , a first conductive layer 32 , and a second conductive layer 33 .

[0068] Specifically, the first conductive layer 32 is formed at one end of the liquid crystal layer 31 close to the outer mirror body 10 and connected to the heat conductive film 50; the second conductive layer 33 is formed at one end of the liquid crystal layer 31 away from the outer mirror body 10, and the first gap 40 is located between the second conductive layer 33 and the inner mirror body 20. The snow goggles 100 also include: a first glass layer 71 disposed at one end of the heat conductive film 50 close to the outer mirror body 10, and a second glass layer 72 disposed at one end of the second conductive layer 33 away from the outer mirror body 10.

[0069] Specifically, the liquid crystal layer 31 can be made of TN liquid crystal material or a liquid crystal material of a dichroic dye. In this embodiment, the liquid crystal layer 31 is made of a liquid crystal material of a dichroic dye. The dichroic dye has different absorption rates for polarized light in the directions perpendicular to and parallel to the molecular axis. It only absorbs polarized light in a certain direction, while polarized light in a direction perpendicular to this direction will pass through. When no voltage is applied to both ends of the first conductive layer 32 and the second conductive layer 33, the liquid crystal molecules of the dichroic dye and the liquid crystal material are perpendicular to the first glass layer 71 and the second glass layer 72, and the directions of natural light and dye absorption of light are perpendicular, so that light can pass freely without being absorbed. When the external ambient light is strong, the user needs the snow goggles 100 to adjust the transmittance and reduce the transmittance of light. At this time, by applying a voltage to both ends of the first conductive layer 32 and the second conductive layer 33, the dichroic dye is parallel to the direction of the first glass layer 71 and the second glass layer 72. At this time, when the light outside the car is irradiated, most of the light is absorbed by the dichroic dye, so that the car window appears dark, thereby reducing the light transmittance.

[0070] Specifically, the first conductive layer 32 and the second conductive layer 33 are made of one or a combination of indium tin oxide or nano silver materials. By using one of indium tin oxide or nano silver materials, since liquid crystal is a fluid, indium tin oxide and nano silver can be prepared into an extremely thin conductive layer, so that the dimming film 30 has a flexible material property and can be flexibly applied to different structures of the snow goggles 100.

[0071] In one embodiment, in order to further improve the thermal conductivity between the outer mirror body 10 and the dimming film 30 so that the temperature of the dimming film 30 is further close to the temperature of the outer mirror body 10, a thermally conductive film 50 is further arranged between the dimming film 30 and the outer mirror body 10. The thermally conductive film 50 is respectively connected to the outer mirror body 10 and the first conductive layer 32. In this embodiment, the thermally conductive film 50 is a silicone sheet made of a transparent material.

[0072] In one embodiment, other functional layers such as a heat-insulating film, a filter film, and an anti-glare film may be further disposed between the dimming film 30 and the first glass layer 71 and the second glass layer 72. For example, a heat-insulating film may be disposed between the dimming film 30 and the second glass layer 72 to further thermally isolate the dimming film 30 from the inner mirror body 20 to balance the temperature difference at both ends of the dimming film 30; or an anti-glare film may be disposed between the dimming film 30 and the first glass layer 71 and the second glass layer 72 to avoid glare to the user during skiing.

[0073] In one embodiment, since one end of the inner lens body 20 is in contact with the human body surface, the user's body temperature inevitably rises during skiing, producing sweat, and the water vapor evaporated from the sweat enters between the outer lens body 10 and the inner lens body 20. Since the temperature difference between the outer lens body 10 and the inner lens body 20 is large, the water vapor is easily cooled and liquefied on the surface of the outer lens body 10. In this embodiment, in order to prevent the water vapor from being cooled and liquefied on the surface of the dimming film 30, resulting in blurred field of view of the ski goggles 100, the outer lens body 10 includes: a first main body 11, a first cavity 12, and a second cavity 13.

[0074] Specifically, the first main body 11 is connected to the endoscope body 20 and the heat-conductive film 50 respectively; the first cavity 12 is formed at one end of the first main body 11 and is connected to the first gap 40; the second cavity 13 is formed at the other end of the first main body 11 and is connected to the first gap 40, so that the air in the first gap 40 is connected to the first cavity 12 and the second cavity 13, and a through hole connected to the outside can be further set in the first cavity 12 or the second cavity 13 to allow convection between the air and the outside.

[0075] In one embodiment, in order to further prevent the water vapor from liquefying when cooled on the dimming film 30 and causing blurred vision of the snow goggles 100, the snow goggles 100 further include: a second gap 61, a first through hole 62, and a heating wire 63.

[0076] Specifically, in order to allow the air around the dimming film 30 to convect with the air in the first cavity 12, the second gap 61 is formed between the dimming film 30 and the first cavity 12, and is respectively connected to the first gap 40 and the first cavity 12; the first through hole 62 is formed on the first main body 11, and is connected to the second gap 61 and the first cavity 12. In order to further balance the temperature difference between the dimming film 30 and the temperature of the air in the first gap 40, and to prevent the water vapor in the first gap 40 from being liquefied when it is cooled on the surface of the dimming film 30, the heating wire 63 is arranged in the first cavity 12 to heat the first main body 11 forming the first cavity 12, thereby increasing the temperature of the dimming film 30 connected to the first main body 11. At the same time, the heating wire 63 also heats the air in the first cavity 12. Due to convection between the air in the first cavity 12 and the air in the first gap 40, the air in the second gap 61 is also heated by the heating wire 63, thereby eliminating the water mist on the side of the dimming film 30 close to the inner mirror body 20 and restoring the clear field of vision of the snow goggles 100.

[0077] More preferably, in order to further prevent the water vapor from liquefying when it encounters cold on the dimming film 30 and causing a blurred field of view of the snow goggles 100 , the snow goggles 100 further include: a third gap 64 , a second through hole 65 , and a third through hole 66 .

[0078] Specifically, the third gap 64 is formed in the dimming film 30 and the second cavity 13, and is respectively connected with the second gap 61 and the second cavity 13; the second through hole 65 is formed on the first main body 11, and connects the third gap 64 with the second cavity 13; the third through hole 66 is formed on the first main body 11, and connects the second cavity 13 with the outside, so that the water vapor in the first gap 40 can convect to the outside of the snow goggles 100 through the second cavity 13.

[0079] In one embodiment, the first main body 11 includes a mirror body 111 and a connecting portion 112 , wherein the connecting portion 112 includes a first connecting portion 1121 , a second connecting portion 1122 , a third connecting portion 1123 , and a fourth connecting portion 1124 .

[0080] Specifically, the mirror body 111 is made of a light-transmitting material, and the heat-conducting film 50 is arranged between the mirror body 111 and the dimming film 30; the connecting portion 112 is formed by extending from the mirror body 111 toward the inner mirror body 20; the connecting portion 112 includes: a first connecting portion 1121 formed at one end of the mirror body 111, a first cavity 12 formed in the first connecting portion 1121, a first through hole 62 formed at one end of the first connecting portion 1121 close to the dimming film 30, and a first through hole 62 formed at one end of the first connecting portion 1121 close to the dimming film 30. A connecting portion 1121 is connected to the inner mirror body 20; a second connecting portion 1122 is formed on the other end of the mirror body 111 opposite to the first connecting portion 1121, a second cavity 13 is formed in the second connecting portion 1122, a second through hole 65 is formed at one end of the second connecting portion 1122 close to the dimming film 30, a third through hole 66 is formed at one end of the second connecting portion 1122 away from the dimming film 30, and the second connecting portion 1122 is connected to the inner mirror body 20. The connecting portion 112 also includes: a third connecting portion 1123, which is formed between the first connecting portion 1121 and the second connecting portion 1122 and is connected to the endoscope body 20; a fourth connecting portion 1124, which is formed between the first connecting portion 1121 and the second connecting portion 1122 and is arranged opposite to the third connecting portion 1123, and the fourth connecting portion 1124 is connected to the endoscope body 20, and the first connecting portion 1121, the second connecting portion 1122, the third connecting portion 1123 and the fourth connecting portion 1124 are integrally formed.

[0081] Specifically, the snow goggles 100 include a first control box 67 and a second control box 68 .

[0082] Specifically, the first control box 67 is arranged on the third connecting portion 1123 and is provided with a control component 73. The control component 73 is electrically connected to the heating wire 63. The control component 73 is used to control the operation of the heating wire 63. When the snow goggles 100 have blurred vision due to water mist, the air temperature in the outer mirror body 10 and the first gap 40 is heated by the heating wire 63, so as to eliminate the water mist attached to the dimming film 30 in the first gap 40; the second control box 68 is arranged on the fourth connecting portion 1124 and is connected to the second cavity 13. A fan 74 is arranged in the second control box 68. The fan 74 is electrically connected to the control component 73. The control component 73 is also used to control the operation of the fan 74. By connecting the second control box 68 with the second cavity 13, the control box is connected to the first gap 40, so that the air flow rate between the first gap 40, the first cavity 12, the second cavity 13 and the second control box 68 is increased by the fan 74, so as to further eliminate the water mist in the snow goggles 100 and improve the clarity of the field of vision.

[0083] In this embodiment, the snow goggles 100 further include: an elastic band 69 and a battery 610. The elastic band 69 is connected to the third connection part 1123 and the fourth connection part 1124 respectively, so that the user can wear the snow goggles 100. The battery 610 is used to control the control element 73, the heating wire 63 and the fan 74. The battery 610 is arranged in the first control box 67 or the second control box 68 and is electrically connected to the control element 73. In this embodiment, two batteries 610 are arranged in the first control box 67 and the second control box 68 respectively to enhance the capacity of the heating wire 63 and the fan 74.

[0084] Thus, a gap is provided between the dimming film 30 and the inner mirror body 20 to separate the dimming film 30 from the inner mirror body 20, so as to prevent the inner mirror body 20 in direct contact with the human body from transmitting the temperature to the dimming film 30, resulting in a large temperature difference between the side of the dimming film 30 close to the outer mirror body 10 and the side of the dimming film 30 close to the inner mirror body 20, thereby balancing the temperature difference of the dimming film 30 and improving the control accuracy of the dimming film 30.
