[0031] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.
[0032] like Figures 1 to 4 As shown, this embodiment provides a pair of glasses 100, which is a smart pair of glasses such as AR glasses, and the glasses 100 is equipped with an eye-tracking component 40. The eye-tracking component 40 includes a light-emitting element 41 and a camera element 42. The light-emitting element 41 is an infrared light emitter or other component that emits infrared detection light towards the eyeball 50. The infrared detection light is reflected by the eyeball 50 and then directed towards the camera element 42. The camera element 42 is a camera or other component that can receive the infrared detection light reflected by the eyeball 50, thereby locating the position of the eyeball 50. The specific principle of eyeball 50 positioning is commonly used in the eye-tracking component 40 of AR glasses 100 in the prior art, and will not be specifically described in this application.
[0033] For ease of reading, this application introduces a first direction X, a second direction Z, and a third direction Y to describe the embodiments of this application. The first direction X, the second direction Z, and the third direction Y can be three non-parallel straight lines in space; further, the first direction X, the second direction Z, and the third direction Y can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction X is described as the X-axis direction of the three-dimensional coordinate system, the second direction Z is the Z-axis direction of the three-dimensional coordinate system, and the third direction Y is the Y-axis direction of the three-dimensional coordinate system.
[0034] The glasses 100 includes a frame 10, two nose pads 20, and two mounting parts 30. The two nose pads 20 are connected to the frame 10 and respectively abut against opposite sides of the nose of the person wearing the glasses 100, thereby ensuring the stability of the glasses 100 when worn. Each nose pad 20 has a first receiving cavity 21 for accommodating a photographic element 42. Each nose pad 20 has a first opening 22 that connects to the first receiving cavity 21 and faces the eyeball 50, allowing the detection light reflected from the eyeball 50 to be directed towards the photographic element 42. The two mounting parts 30 are connected to the frame 10 and are spaced apart along a first direction X, with the two nose pads located between the two mounting parts 30. The mounting part 30 is provided with a second receiving cavity 31 for receiving the light-emitting element 41. The mounting part 30 is provided with a second opening 32, which is connected to the second receiving cavity 31 and is positioned towards the eyeball 50 so that the detection light emitted by the light-emitting element 41 can be directed toward the eyeball 50.
[0035] Thus, the glasses 100 of this application, by creating a first receiving cavity 21 within the nose pad 20, can directly utilize the internal space of the nose pad 20 to install the imaging component 42, eliminating the need for additional shell structures on the frame 10 to install the imaging component 42, thereby ensuring the aesthetic appearance of the entire glasses 100. Furthermore, since the imaging component 42 is installed within the first receiving cavity 21 and receives external light through the first opening 22, while the light-emitting component 41 is installed within the second receiving cavity 31 and emits light to the outside through the second opening 32, this avoids the imaging component 42 and the light-emitting component 41 being exposed and affecting the aesthetics of the glasses 100.
[0036] Please combine Figures 1 to 4 In one embodiment, the frame 10 includes two lens rings 11, which are generally annular in shape and configured to mount lenses 60. The two lens rings 11 are spaced apart along a first direction X and are connected by a connecting portion 12, which is integrally formed with the two lens rings 11.
[0037] The frame 10 also includes two temples 13, which are rotatably connected to opposite ends of the two lens rings 11 along the first direction X, so as to fold or unfold the two temples 13.
[0038] Two nose pads 20 are respectively connected to two lens rings 11, and both nose pads 20 and two temples 13 are located on the side of the lens ring 11 closer to the eyeball 50. In addition, along the first direction X, the two nose pads 20 are respectively connected to the edges of the two lens rings 11 on the adjacent sides, so that the two nose pads 20 are spaced apart along the first direction X, and the two nose pads 20 are respectively provided with the aforementioned first opening 22 on the opposite sides, and the two first openings 22 are respectively positioned facing the two eyeballs 50.
[0039] Specifically, along the first direction X, the surfaces of the two nose pads 20 on opposite sides are curved, and the curved surfaces are oriented toward the eyeball 50 corresponding to the nose pad 20, so that the first opening 22 opened on the curved surface is oriented toward the eyeball 50.
[0040] It is understood that in other embodiments, the two nose pads 20 are inclined relative to each other, and the tops of the two nose pads 20 are connected to each other, so that the two nose pads 20 are a single unit, which facilitates the installation of the nose pads 20. The tops of the two nose pads 20 can be connected by integral molding.
[0041] In this embodiment, there are two mounting portions 30, each connected to one of the two lens rings 11. The mounting portions 30 can be integrally formed into the lens rings 11 to improve assembly efficiency. Each mounting portion 30 contains a light-emitting element 41, which, together with the corresponding shooting element 42, forms two sets of eye-tracking components 40. These two sets of eye-tracking components 40 track the positions of the wearer's two eyeballs 50, thereby improving the accuracy of eyeball tracking. The mounting portions 30 and the nose pads 20 are located on the same side of the lens rings 11, meaning the mounting portions 30 are connected to the side of the lens rings 11 closest to the eyeballs 50. Furthermore, the mounting portions 30 are located at the lower edge of the lens rings 11, and along the second direction Z, they are spaced apart near the ground side of the nose pads 20.
[0042] Specifically, along the third direction Y, the surface of the mounting part 30 away from the lens ring 11 is an inclined surface, which is set toward the eyeball 50 corresponding to the nose pad 20, so that the second opening 32 opened on the inclined surface is set toward the eyeball 50.
[0043] It is understood that in other embodiments, along the second direction Z, the mounting part 30 is provided on the near-ground side of the nose pad 20, and the mounting part 30 is integrally formed with the nose pad 20, that is, the mounting part 30 is part of the structure of the nose pad 20, so that both the imaging element 42 and the light-emitting element 41 can be installed in the nose pad 20.
[0044] Please combine Figures 1 to 4 In one embodiment, along the third direction Y, the distance between the imaging element 42 located in the first receiving cavity 21 and the eyeball 50 is set as the first distance H1, and the distance between the light-emitting element 41 located in the second receiving cavity 31 and the eyeball 50 is set as the second distance H2, wherein the first distance H1 is less than the second distance H2.
[0045] Along the third direction Y, the curved surface of the nose pad 20 on the side away from the lens ring 11 is closer to the eyeball 50 than the inclined surface of the mounting part 30 on the side away from the lens ring 11, so that the first opening 22 is closer to the eyeball 50 than the second opening 32, thereby making the imaging element 42 closer to the eyeball 50 than the light-emitting element 41.
[0046] In one embodiment, taking a standard head shape commonly used in the prior art as an example, the range of both the first distance H1 and the second distance H2 is 20-35mm. At this time, the positions of the imaging element 42 and the light-emitting element 41 can ensure that the eye-tracking effect of the eyeball 50 is excellent.
[0047] Furthermore, the eyeball 50 has a defined central axis M, the direction of which is parallel to the third direction Y. Along the third direction Y, the eyeball 50 has a vertex D on the side near the frame 10, the vertex D is approximately located at the center of the surface of the eyeball 50, and the vertex D is located on the central axis M.
[0048] The line connecting the center point of the first opening 22 and the vertex D is designated as the first line L1. The first line L1 and the central axis M form a first angle R1, with an angle of 49° to 55°. The line connecting the center point of the second opening 32 and the vertex D is designated as the second line L2. The second line L2 and the central axis M form a second angle R2, with an angle of 39° to 45°.
[0049] Thus, by limiting the specific numerical range of the angle between the shooting element 42 and the light-emitting element 41 and the eyeball 50, the position of the shooting element 42 and the light-emitting element 41 based on the non-standard head shape can be limited, ensuring the tracking effect of the eyeball 50.
[0050] Please combine Figures 5 to 7 In one embodiment, the glasses 100 further includes a conductive element 70. A mounting cavity 16 is provided within the frame 10, and the conductive element 70 is located within the mounting cavity 16. The mounting cavity 16 communicates with a first receiving cavity 21, allowing the conductive element 70 to partially extend into the first receiving cavity 21. The imaging element 42 is electrically coupled to the conductive element 70 extending into the first receiving cavity 21. The mounting cavity 16 communicates with a second receiving cavity 31, allowing the conductive element 70 to partially extend into the second receiving cavity 31. The light-emitting element 41 is electrically coupled to the conductive element 70 extending into the second receiving cavity 31.
[0051] Specifically, the frame 10 includes a first frame portion 14 and a second frame portion 15. Along a third direction Y, the second frame portion 15 is detachably connected to one side of the first frame portion 14, and a mounting cavity 16 is formed between the first frame portion 14 and the second frame portion 15. Both temples 13 are rotatably connected to the second frame portion 15. The first frame portion 14 and the second frame portion 15 have substantially the same shape, and both have the areas corresponding to the two lens rings 11 mentioned above. The nose pad 20 and the mounting portion 30 are both connected to the side of the second frame portion 15 away from the first frame portion 14.
[0052] The mounting cavity 16 includes two sub-cavities 161 and an intermediate cavity 162. The two sub-cavities 161 correspond to two lens rings 11 respectively, and are arranged around the lens 60 mounted on their respective lens rings 11. The intermediate cavity 162 is located between the two sub-cavities 161 and corresponds to the connecting part 12. The two sub-cavities 161 are connected through the intermediate cavity 162.
[0053] The number of conductive elements 70 is set to two, and the two conductive elements 70 are located in the two sub-cavities 161 respectively. The two conductive elements 70 are correspondingly arranged with the two sets of eye-tracking components 40 mentioned above, so as to electrically couple with the imaging component 42 and the light-emitting component 41 in the same eye-tracking component 40 through the conductive elements 70.
[0054] The conductive component 70 is provided with a first conductive protrusion 71 and a second conductive protrusion 72. Both the first conductive protrusion 71 and the second conductive protrusion 72 are integrally formed with the conductive component 70 and are made of the same material, namely a conductive material such as metal. The first conductive protrusion 71 extends into the first receiving cavity 21 and is electrically coupled to the imaging component 42. The second conductive protrusion 72 extends into the second receiving cavity 31 through the connecting port 150 provided on the second frame portion 15 and is electrically coupled to the light-emitting component 41. Furthermore, the connecting port 150 facilitates the insertion of the light-emitting component 41 into the second receiving cavity 31.
[0055] Along the first direction X, the nose pad 20 has an installation opening 23 on the side near the other nose pad 20. The frame 10 also includes a nose pad 24, which is connected to the nose pad 20 and closes the installation opening 23. The nose pad 24 may be made of an elastic material such as rubber so as not to cause discomfort to the user when the nose pad 24 contacts the nose.
[0056] The nose pad 24 has a protruding mounting base 240. The portion of the first conductive protrusion 71 that extends into the first receiving cavity 21 is held in place by the mounting base 240 to ensure the stability of the first conductive protrusion 71 and prevent it from shaking and affecting the normal operation of the imaging piece 42.
[0057] Furthermore, the glasses 100 also includes a circuit assembly 80. The circuit assembly 80 is located within the intermediate cavity 162 and consists of components such as a circuit board, control elements, and a battery. The conductive element 70 is electrically connected to the circuit assembly 80 to enable signal exchange and other operations between the conductive element 70 and the components on the circuit assembly 80.
[0058] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the scope of this application. All such changes and substitutions fall within the scope defined by this application.
