Description

Technical Field

[0001] This application relates to the field of wearable device technology, and in particular to an ear hook mechanism and its MR-based display device. Background Technology

[0002] The ear hook mechanism and its MR-based display device are devices that seamlessly integrate virtual content with the real world by combining virtual reality (VR) and augmented reality (AR) technologies. MR technology not only allows users to see virtual objects, but also allows these virtual objects to interact with the real environment. MR display devices use advanced sensors, cameras and display technologies to overlay digital content onto the real world, enabling users to see and operate virtual objects in a real environment.

[0003] Currently, a Chinese utility model patent application, published on July 25, 2025, with publication number CN 223155313 U, provides a smart glasses design. This smart glasses includes a front frame and temples. The temples consist of a first segment, a second segment, and a third segment. The front end of the first segment is connected to the front frame, the rear end of the first segment is connected to the front end of the second segment, and the rear end of the second segment is connected to one end of the third segment. The second and third segments form an ear-hook structure, with the second segment contacting the upper side of the user's ear. The ear-hook structure has an ear-hook shape. When the ear-hook structure is in this shape, the end of the third segment furthest from the second segment is located below the end of the third segment that connects to the second segment, and the end of the third segment furthest from the second segment is located in front of the end of the third segment that connects to the second segment. The third segment is used to contact the back of the user's ear. This design prevents the smart glasses from slipping off the user's head.

[0004] In related technologies, smart glasses feature a fixed, one-piece ear hook design. While this design offers simplicity and consistency in manufacturing and assembly, its biggest drawback is the lack of flexibility. Because the ear hook shape is fixed, it cannot be adjusted to suit the shape and size of different users' ears. Each person's ear shape is unique, including the size of the auricle, the shape of the earlobe, and the angle of the ear root, all of which affect wearing comfort. Furthermore, the ear hook structure connects to a Bluetooth headset, which has no power supply to the overall smart glasses, making it inconvenient to use.

[0005] Therefore, it is necessary to propose an ear hook mechanism and its MR-based display device to solve the above problems. Utility Model Content

[0006] This application provides an ear hook mechanism and a display device based on MR technology to improve the technical problems existing in related technologies, such as the fixed shape of the ear hook, lack of flexibility, inability to be adjusted according to the shape and size of different users' ears, affecting wearing comfort, and lack of power supply for the headphones.

[0007] This application provides an ear hook mechanism and a display device based on MR technology. The ear hook mechanism includes a connecting leg, on which an ear hook is provided. The ear hook includes a first segment, a second segment, and a third segment. The front end of the first segment is connected to the connecting leg for contacting the upper side of the user's ear. The front end of the second segment is connected to the rear end of the first segment for contacting the back side of the user's ear. The front end of the third segment is connected to the rear end of the second segment for contacting the front side of the user's ear. The first segment, the second segment, and the third segment are all deformable. An earphone component is provided on the end of the third segment away from the second segment. The ear hook is electrically connected to the connecting leg to facilitate power supply to the earphone component.

[0008] The technical solution described above in this application embodiment has at least the following technical effects: by dividing the ear hook into a first segment, a second segment, and a third segment, which respectively contact the upper, back, and front sides of the user's ear, it can better adapt to different users' ear shapes. Each segment can deform, which means that the ear hook can automatically adjust according to the user's ear shape. At the same time, the earphone components are directly integrated into the ear hook, and the glasses directly power the earphones, avoiding the hassle of additional cables or separate earphones.

[0009] In this embodiment, a first electrical connection terminal group is provided on one end of the connecting leg near the first segment, and a second electrical connection terminal group is provided on one end of the first segment near the connecting leg. The first electrical connection terminal group and the second electrical connection terminal group are in electrical contact, and the earphone component is electrically connected to the second electrical connection terminal group through the first electrical connection terminal group.

[0010] This technical solution achieves a modular connection between the headphone component and the main body of the device through the electrical contact connection of the first electrical connection terminal group and the second electrical connection terminal group. This design allows the headphone component to be easily disassembled and replaced, improving the maintainability of the device. The electrical contact connection of the electrical connection terminal group eliminates the traditional cable connection between the headphone component and the main body of the device, reduces the use of internal cables, lowers the risk of cable tangling, breakage or poor contact, and improves the reliability of the device.

[0011] In this embodiment, the first segment, the second segment, and the third segment are all made of snake tubes.

[0012] This technical solution uses a snake tube structure composed of multiple flexible joints, which can bend and twist freely in multiple directions. This allows the ear hook to be precisely adjusted according to the ear shape of different users, ensuring comfort and stability when wearing it. The flexibility of the snake tube structure allows it to distribute the wearing pressure evenly, avoiding the problem of traditional fixed-shape ear hooks applying excessive pressure to a specific area.

[0013] In this embodiment, a limiting component is provided on one end of the connecting leg near the ear bracket, and the limiting component is used to limit the displacement between the connecting leg and the second electrical connection terminal group.

[0014] This technical solution effectively prevents relative displacement between the connecting leg and the second electrical connection terminal group, ensuring that the electrical connection between the two remains stable.

[0015] In this embodiment, the limiting component includes an extension bar, a connecting bar, and a locking block. The extension bar is disposed on the connecting leg, the connecting bar is disposed on the end of the extension bar away from the connecting leg, and the locking block is disposed on the end of the connecting bar away from the extension bar. A limiting groove is formed on the second connecting terminal group.

[0016] With this technical solution, the extension strip is used to create a gap between the connecting strip and the connecting leg. The connecting strip drives the locking block to limit the position in the limiting groove. The cooperative design of the locking block and the limiting groove can achieve a precise limiting function, ensuring that the relative position between the connecting leg and the second electrical connection terminal group remains fixed.

[0017] In this embodiment, the width of the limiting groove is greater than the width of the connecting strip, and a pressing block is provided on the middle part of the connecting strip.

[0018] With this technical solution, the width of the limiting groove is greater than the width of the connecting strip, which means that the connecting strip has a certain tolerance space when inserted into the limiting groove. This makes the insertion process easier. Because the limiting groove is wider, the connecting strip will not get stuck in the limiting groove due to being too tight, avoiding difficulties during disassembly. Because the limiting groove is wider and the pressing block in the middle of the connecting strip is easy to press, users can easily insert and disassemble with one hand.

[0019] In this embodiment, the outer wall of the snake tube is covered with a skin-friendly rubber layer.

[0020] This technical solution provides a soft, skin-friendly rubber layer that offers a more comfortable feel and reduces skin irritation and friction.

[0021] In this embodiment, the ear hook can be replaced with a regular eyeglass temple by means of a limiting component and a first point connecting terminal group.

[0022] With this technical solution, users can replace the ear hooks with ordinary eyeglass temples and use the smart glasses as ordinary glasses when the smart functions are not needed.

[0023] This application provides a display device based on MR technology, including MR glasses and an ear hook mechanism as described above, wherein the ear hook mechanism is disposed on the MR glasses via the connecting leg.

[0024] The technical solution described above in this application combines MR glasses with an ear hook mechanism. Through replaceable ear hooks and ordinary eyeglass temples, precise positioning of limiting components, stability of multi-point contact, multi-functional integration, and the application of high-strength materials, this combined design not only improves wearing comfort and enhances device stability, but also improves user experience, device durability, and multi-functional application capabilities.

[0033] In related technologies, smart glasses feature a single, integrated ear hook design, meaning the shape of the ear hook is fixed. While this design offers simplicity and consistency in manufacturing and assembly, its biggest drawback is the lack of flexibility. Because the ear hook shape is fixed, it cannot be adjusted to suit the shape and size of different users' ears. Each person's ear shape is unique, including the size of the auricle, the shape of the earlobe, and the angle of the ear root, all of which affect wearing comfort.

[0034] Based on this, in order to improve the technical problems existing in the related technology, such as the fixed shape of the ear hook, lack of flexibility, inability to be adjusted according to the shape and size of different users' ears, affecting the wearing comfort, and lack of power supply for the headphones, the embodiments of this application provide the following solutions.

[0035] Please refer to the following: Figures 1 to 6 This application provides an ear hook mechanism and a display device based on MR technology. The ear hook mechanism includes a connecting leg 1, on which an ear hook 2 is provided. The ear hook 2 includes a first segment 21, a second segment 22, and a third segment 23. The front end of the first segment 21 is connected to the connecting leg 1 for contacting the upper side of the user's ear. The front end of the second segment 22 is connected to the rear end of the first segment 21 for contacting the back side of the user's ear. The front end of the third segment 23 is connected to the rear end of the second segment 22 for contacting the front side of the user's ear. The first segment 21, the second segment 22, and the third segment 23 can all be deformable. An earphone component 3 is provided on the end of the third segment 23 away from the second segment 22. The ear hook 2 is electrically connected to the connecting leg 1 to facilitate power supply to the earphone component 3.

[0036] This application embodiment provides an ear hook mechanism. The ear frame is divided into a first segment 21, a second segment 22, and a third segment 23, which respectively contact the upper, back, and front sides of the user's ear, allowing for better adaptation to different ear shapes. Each segment is deformable, meaning the ear hook 2 can automatically adjust according to the user's ear shape. The first segment 21 (contacting the upper side of the ear) can be adjusted according to the height and curvature of the auricle to ensure that excessive pressure is not applied to the auricle during wearing. The second segment 22 (contacting the back side of the ear) can be adjusted according to the angle and thickness of the ear root to ensure proper ear hooking. The stability of the frame 2 is enhanced by the third segment 23 (which contacts the front of the ear) which can be adjusted according to the shape and size of the earlobe to ensure comfort during wear. The earphone component 3 is directly integrated into the ear hook 2, away from the end of the connecting leg 1, avoiding the hassle of additional cables or separate earphones. This integrated design makes the entire device more compact, reduces space occupation, and improves portability. The earphone component 3 is located at the end of the ear hook 2 away from the connecting leg 1, which helps to balance the weight distribution of the device and avoids discomfort caused by the weight being concentrated on one side. The connecting leg also supplies power to the earphone.

[0037] In this embodiment, a first electrical connection terminal group 31 is provided on one end of the connecting leg 1 near the first segment 21, and a second electrical connection terminal group 32 is provided on one end of the first segment 21 near the connecting leg 1. The first electrical connection terminal group 31 and the second electrical connection terminal group 32 are in electrical contact, and the earphone component 3 is electrically connected to the second electrical connection terminal group 32 through the first electrical connection terminal group 31.

[0038] With this configuration, the headphone component 3 and the device body are modularly connected through the electrical contact connection of the first electrical connection terminal group 31 and the second electrical connection terminal group 32. This design allows the headphone component 3 to be easily disassembled and replaced, improving the maintainability of the device. The electrical contact connection of the electrical connection terminal group eliminates the traditional cable connection between the headphone component 3 and the device body, reducing the use of internal cables and lowering the risk of cable tangling, breakage, or poor contact, thus improving the reliability of the device. It also avoids the situation where the glasses body cannot power the headphones because it is a Bluetooth headset. Users can easily connect or disconnect the headphone component 3 from the device body, improving the ease of use of the device.

[0039] In this embodiment, the first segment 21, the second segment 22, and the third segment 23 are all made of serpentine tubes.

[0040] With this design, the snake tube structure consists of multiple flexible joints, which can bend and twist freely in multiple directions. This allows the ear hook 2 to be precisely adjusted according to the ear shape of different users, ensuring comfort and stability when wearing it. The flexibility of the snake tube structure allows it to distribute the wearing pressure evenly, avoiding the problem of traditional fixed-shape ear hooks applying excessive pressure to a specific part. The snake tube is usually made of high-strength metal or composite material, which has good durability and tensile strength.

[0041] In this embodiment, a limiting component 4 is provided on one end of the connecting leg 1 near the ear bracket 2. The limiting component 4 is used to limit the displacement between the connecting leg 1 and the second electrical connection terminal group 32.

[0042] With this configuration, the limiting component 4 can effectively prevent relative displacement between the connecting leg 1 and the second electrical connection terminal group 32, ensuring that the electrical connection between the two remains stable. By limiting displacement, the limiting component 4 ensures that the contact points between the electrical connection terminal groups will not experience poor contact due to loosening, thereby ensuring the continuity and stability of audio signal and power transmission.

[0043] In this embodiment, the limiting component 4 includes an extension bar 41, a connecting bar 42, and a locking block 43. The extension bar 41 is disposed on the connecting leg 1, the connecting bar 42 is disposed on the end of the extension bar 41 away from the connecting leg 1, and the locking block 43 is disposed on the end of the connecting bar 42 away from the extension bar 41. A limiting groove 44 is formed on the second connecting terminal group.

[0044] With this configuration, the extension bar 41 is used to create a gap between the connecting bar 42 and the connecting leg 1. The connecting bar 42 drives the locking block 43 to limit the movement within the limiting groove 44. The cooperative design of the locking block 43 and the limiting groove 44 enables precise limiting, ensuring that the relative position between the connecting leg 1 and the second electrical connection terminal group 32 remains fixed. The limiting component 4 can reduce mechanical wear between the connecting leg 1 and the electrical connection terminal group, extending the service life of the equipment.

[0045] In this embodiment, the width of the limiting groove 44 is greater than the width of the connecting strip 42, and a pressing block 45 is provided on the middle part of the connecting strip 42.

[0046] With this design, the width of the limiting groove 44 is greater than the width of the connecting strip 42, which means that the connecting strip 42 has a certain tolerance space when inserted into the limiting groove 44. This makes the insertion process easier. Because the limiting groove 44 is wider, the connecting strip 42 will not get stuck in the limiting groove 44 due to being too tight, avoiding difficulties during disassembly. Because the limiting groove 44 is wider and the pressing block 45 in the middle of the connecting strip 42 is easy to press, users can easily insert and disassemble with one hand.

[0047] In this embodiment, the outer wall of the snake tube is covered with a skin-friendly rubber layer 5.

[0048] With this design, the skin-friendly rubber layer 5 has a soft texture, providing a more comfortable feel and reducing skin irritation and friction.

[0049] In this embodiment, the ear hook 2 can be replaced with a regular eyeglass temple 6 by using the limiting component 4 and the first point connection terminal group.

[0050] With this setup, when the smart features are not needed, users can replace the ear hooks 2 with regular eyeglass temples 6 and use the smart glasses as regular glasses. Users can choose to use either the ear hooks 2 or the regular eyeglass temples 6 according to their wearing habits and comfort.

[0051] This application provides a display device based on MR technology, including MR glasses 7 and any of the above-mentioned ear-hook mechanisms, wherein the ear-hook mechanism is mounted on the MR glasses 7 via a connecting leg 1.

[0052] The technical solution described above in this application combines MR glasses 7 with an ear hook mechanism. Through the replacement ear hooks 2 and ordinary eyeglass temples 6, the precise positioning of the limiting component 4, the stability of multi-point contact, multi-functional integration, and the application of high-strength materials, this combined design not only improves wearing comfort and enhances device stability, but also improves user experience, device durability, and multi-functional application capabilities. At the same time, the MR glasses can be any smart glasses on the market, such as the smart glasses with publication number TH2101001169A. It is an imaging device that can capture the real-world view within the operator's field of vision and a display device that displays a virtual image superimposed on the operator's head, making it convenient for users to use.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
