[0002] Currently, virtual reality technology is maturing, and the application scenarios of head-mounted devices are constantly expanding to a wider range, such as movies, games, and social networking.

[0003] However, different users have different head circumferences, and there are differences between men and women, children and the elderly, as well as different ethnic groups. In order to improve the user experience, users can choose whether to use the top strap of the head-mounted device according to their own usage situation. This requires that the top strap can be quickly installed and removed according to the actual situation.

[0004] Therefore, designing a mechanism that enables quick assembly and disassembly of the top strap without affecting the aesthetics of the device has become a pressing issue for head-mounted devices. Summary of the Invention

[0005] This application provides a strap assembly and a headband device that enables quick assembly and disassembly of the top strap without affecting the device's aesthetics, reducing user operating costs and improving assembly and disassembly efficiency.

[0006] This application provides a strap-fitting assembly, including:

[0007] A first fitting component is provided with a main body and a bent portion. A pull ring is provided at one end of the main body away from the bent portion. The pull ring is used to detachably connect to the top strap of the head-mounted device.

[0008] The second mating component includes a mating cavity, a first magnet, and a second magnet. The first magnet is provided at the top of the mating cavity, and the second magnet is provided at the bottom of the mating cavity. A mating hole is also provided at the top. The main body is inserted through the mating hole, and the bent part is movably disposed between the first magnet and the second magnet.

[0009] When the bent portion attracts the first magnet, the main body extends out of the mating hole so that the pull ring is exposed outside the second mating member;

[0010] When the bent portion attracts the second magnet, the main body is located within the mating cavity so that the pull ring is hidden within the second mating member.

[0011] In some embodiments, the main body is further provided with a pull rod, which is disposed adjacent to the pull ring;

[0012] When the bent portion attracts the second magnet, the pull rod covers the mating hole.

[0013] In some embodiments, the upper end of the pull rod is arc-shaped, and the lateral length of the lower end of the pull rod is greater than the lateral length of the mating hole.

[0014] In some embodiments, foam is provided around the mating hole, and when the pull rod covers the mating hole, the pull rod is hidden in the foam.

[0015] In some embodiments, a cover is provided on the mating hole, the cover being used to cover the mating hole when the bent portion is attracted to the second magnet.

[0016] In some embodiments, the strap mating assembly further includes a strap receiving groove, which is disposed adjacent to the second mating member and is used to receive the top strap.

[0017] In some embodiments, the main body and the bent portion are made of a single piece of metal material.

[0018] In some embodiments, the main body is made of a non-metallic material, and the bent portion is made of a metallic material.

[0019] In some embodiments, the bending angle between the main body and the bent portion is less than or equal to 90 degrees.

[0020] This application also provides a head-mounted device, including a device body, a battery compartment assembly, a top strap, side straps, and a strap-fitting assembly as described in any of the above embodiments;

[0021] The device body and the battery compartment assembly are arranged opposite to each other. The side straps are symmetrically installed on both sides of the device body and both sides of the battery compartment assembly. The strap mating assembly is installed on the battery compartment assembly. The first end of the top strap is detachably connected to the top of the device body, and the second end of the top strap is detachably connected to the pull ring on the first mating member of the strap mating assembly.

[0022] This application provides a strap fitting assembly and a head-mounted device. The strap fitting assembly is applied to a head-mounted device and includes a first fitting member and a second fitting member. The first fitting member has a main body and a bent portion. A pull ring is provided at the end of the main body away from the bent portion for detachable connection with the top strap of the head-mounted device. The second fitting member includes a fitting cavity, a first magnet, and a second magnet. The first magnet is provided at the top end of the fitting cavity, and the second magnet is provided at the bottom end of the fitting cavity. A fitting hole is also provided at the top end, and the main body is inserted into the fitting hole. The bent portion is movably disposed between the first magnet and the second magnet. When the bent portion and the first magnet attract each other, the main body extends out of the fitting hole so that the pull ring is exposed outside the second fitting member. When the bent portion and the second magnet attract each other, the main body is located inside the fitting cavity so that the pull ring is hidden inside the second fitting member. This embodiment of the application utilizes the interaction between the bent portion in the first mating component and the magnet in the second mating component to achieve quick assembly and disassembly of the top strap of the head-mounted device. When the top strap is needed, the pull ring is exposed due to the attraction between the bent portion and the first magnet, allowing the user to easily thread the top strap onto the pull ring. When the top strap is not needed, the user can remove the top strap from the pull ring, and the pull ring can be hidden by the attraction between the bent portion and the second magnet, without affecting the aesthetics of the head-mounted device. This allows for quick assembly and disassembly of the top strap without compromising the device's appearance, reducing user operating costs and improving assembly and disassembly efficiency.

[0037] The embodiments of this application can be applied to various application scenarios such as Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), and games.

[0038] First, some of the nouns or terms that appear in the description of the embodiments of this application are explained as follows:

[0039] Virtual Reality (VR) is a technology for creating and experiencing virtual worlds. It computationally generates a virtual environment, which is a multi-source information (virtual reality mentioned in this article includes at least visual perception, and may also include auditory perception, tactile perception, motion perception, and even taste perception, olfactory perception, etc.) that realizes the fusion of virtual environment, interactive three-dimensional dynamic visual scenes and simulation of physical behavior, allowing users to immerse themselves in the simulated virtual reality environment, and enabling applications in various virtual environments such as maps, games, videos, education, medical care, simulation, collaborative training, sales, assisted manufacturing, maintenance and repair.

[0040] Augmented Reality (AR) is a technology that calculates the camera's pose parameters in the real world (or 3D world, the real world) in real time during image capture, and adds virtual elements to the captured images based on these parameters. Virtual elements include, but are not limited to, images, videos, and 3D models. The goal of AR technology is to overlay the virtual world onto the real world on a screen for interactive experiences.

[0041] Mixed Reality (MR) is a simulated scene that integrates computer-created sensory input (e.g., virtual objects) with sensory input or its representation from a physical setting. In some MR scenes, the computer-created sensory input can adapt to changes in sensory input from the physical setting. Additionally, some electronic systems used to present MR scenes can monitor orientation and / or position relative to the physical setting, enabling virtual objects to interact with real objects (i.e., physical elements from the physical setting or their representations). For example, the system can monitor motion so that virtual plants appear stationary relative to physical buildings.

[0042] For details, please refer to Figures 1 to 4 This application provides a strap-fitting assembly. This strap-fitting assembly 10 can be applied to, for example... Figures 5 to 7 The head-mounted device 100 is shown. The strap fitting assembly 10 includes a first fitting member 11 and a second fitting member 12.

[0043] The first mating part 11 is provided with a main body 111 and a bending part 112. A pull ring 1111 is provided at one end of the main body 111 away from the bending part 112. The pull ring 1111 is used to detachably connect with the top strap 40 of the head-mounted device 100.

[0044] The second mating component 12 includes a mating cavity 121, a first magnet 122, and a second magnet 123. The first magnet 122 is provided at the top end 121a of the mating cavity 121, and the second magnet 123 is provided at the bottom end 121b of the mating cavity 121. A mating hole 1211 is also provided at the top end 121a. The main body 111 is inserted into the mating hole 1211, and the bent part 112 is movably disposed between the first magnet 122 and the second magnet 123.

[0045] Among them, such as Figure 1 As shown, when the bent portion 112 and the first magnet 122 are attracted to each other, the main body portion 111 extends out of the mating hole 1211 so that the pull ring 1111 is exposed outside the second mating member 12. Wherein, Figure 1 The dotted line indicates that the dotted structure of the pull ring 1111 is covered within the top strap 40.

[0046] Among them, such as Figure 2 As shown, when the bent portion 112 and the second magnet 123 are attracted to each other, the main body 111 is located within the mating cavity 121 so that the pull ring 1111 is hidden within the second mating member 12. Figure 1 The dotted line indicates that the dotted structure of the pull ring 1111 is hidden within the second mating part 12.

[0047] For example, the first magnet 122 and the second magnet 123 can be glued together in the mating cavity 121. Alternatively, the first magnet 122 and the second magnet 123 can be snapped together or embedded in the mating cavity 121.

[0048] In this embodiment, the use of the bent portion 112 in the first mating member 11 and the magnet in the second mating member 12 can achieve the following: Figure 5 The headband 40 of the head-mounted device 100 shown is quick to attach and detach. For example, when the top strap 40 is not in use, the pull ring 1111 on the first mating member 11 is generally hidden in the mating hole 1211 of the second mating member 12. When the user needs to use the top strap 40, he / she can manually pull out the pull ring 1111. At this time, the bent portion 112 at the end away from the pull ring 1111 is attracted to the first magnet 122 (e.g., Figure 1 As shown), the pull ring 1111 is exposed due to the attraction between the bent portion 112 and the first magnet 122, making it convenient for the user to thread the top strap 40 onto the pull ring 1111. After threading the top strap 40 onto the pull ring 1111, the top strap can be used normally. When the user no longer needs to use the top strap 40, after removing the top strap 40 from the pull ring 1111, the user presses down on the pull ring 1111. At this time, the bent portion 112 at the end away from the pull ring 1111 is attracted to the second magnet 123 (as shown). Figure 2 As shown, the pull ring 1111 is almost completely hidden in the first mating part 12. Only because part of the edge of the pull ring 1111 protrudes outside the first mating part 12, the pull ring 1111 can be hidden by the attraction between the bent part 112 and the second magnet 123. This does not affect the aesthetics of the head-mounted device 100, and allows for quick assembly and disassembly of the top strap 40. The structure is simple and highly reliable. At the same time, it does not affect the aesthetics of the device after disassembly, reducing user operating costs and improving assembly and disassembly efficiency.

[0049] In some embodiments, the main body 111 may also be provided with a pull rod 1112, which is disposed adjacent to the pull ring 1111. When the bent portion 112 and the second magnet 123 are attracted to each other, the pull rod 1112 covers the mating hole 1211, and the pull rod 1112 is used by the user to pull the pull ring 1111 out of the second mating member 12 by pulling the pull rod 1112. By providing the pull rod 1112 at the upper edge of the pull ring 1111, the pull rod 1112 can cover the mating hole 1211 when the user does not need to use the top strap 40, so as to prevent dust, water and moisture. When the user needs to pull out the pull ring 1111, the pull rod 1112 can be pulled out to pull out the pull ring 1111, which is convenient for the user.

[0050] In some embodiments, the upper end of the pull rod 1112 can be arc-shaped, and the lateral length of the lower end of the pull rod 1112 is greater than the lateral length of the mating hole 1211. The lower end of the pull rod 1112 can limit the downward movement of the pull rod 1112, preventing excessive compression of the second magnet 123 by the bent part 112 when the user presses it hard. The arc-shaped design of the upper end of the pull rod 1112 not only provides a position for the user to pull, but also has better visual aesthetics and better anti-scratch effect.

[0051] In some embodiments, foam (not shown) may be provided around the mating hole 1211. When the pull rod 1112 covers the mating hole 1211, the pull rod 1112 is hidden in the foam. By providing foam around the mating hole 1211, the pull rod 1112 of the first mating member 11 can be completely hidden. When the strap pull ring 1111 assembly is applied to the head-mounted device 100, the pull rod 1112 is not visible from the outside, making the overall appearance of the head-mounted device 100 more aesthetically pleasing.

[0052] In some embodiments, a cover (not shown) may be provided on the mating hole 1211. The cover is used to cover the mating hole 1211 when the bent portion 112 and the second magnet 123 are attracted to each other. For example, the cover may have an outwardly protruding groove that can completely cover the edge of the pull ring 1111 protruding from the first mating member 12 when the bent portion 112 and the second magnet 123 are attracted to each other, or the groove can completely cover the pull rod 1112 protruding from the first mating member 12. By providing the cover, the first mating member 11 can be completely hidden, preventing the first mating member 11 from scratching other items, and also providing dustproof, waterproof, and moisture-proof functions.

[0053] In some embodiments, the strap mating assembly 10 further includes a strap receiving slot (not shown), which is disposed adjacent to the second mating member 12 and is used to receive the top strap 40. By providing the strap receiving slot, the top strap can be received when it is not in use, thus preventing the top strap from being lost.

[0054] In some embodiments, the main body 111 and the bent portion 112 are made of a single piece of metal. The main body 111 and the bent portion 112, made of a single piece of metal, are integrally molded parts, resulting in a simpler manufacturing process and a more robust structure.

[0055] In some embodiments, the main body 111 is made of a non-metallic material, and the bent portion 112 is made of a metallic material. Using a metallic material for the main body 111 can reduce production costs and weight, while using a metallic material for the bent portion 112 is to ensure that the bent portion 112 can be attracted to a magnet.

[0056] In some embodiments, the bending angle θ between the main body portion 111 and the bending portion 112 is less than or equal to 90 degrees.

[0057] Figure 4 In Figure 4 a and Figure 4 c can be Figure 1 Cross-sectional view of the tie-on assembly 10. Figure 4 In Figure 4 b and Figure 4 d can be Figure 2 Cross-sectional view of the middle strap fitting component 10, in Figure 4 In the view, it is not visible Figure 1 The pull ring shown is 1111.

[0058] like Figure 4 In Figure 4 a and Figure 4 b illustrates a structure where the bending angle θ between the main body 111 and the bent portion 112 is 90 degrees. A bending angle θ of 90 degrees simplifies the manufacturing process and reduces the defect rate during production. For example... Figure 4 As shown in diagram a, when the bent portion 112 and the first magnet 122 are attracted to each other, the main body portion 111 extends out of the mating hole 1211 so that the pull ring 1111 on the main body portion 111 protrudes from the second mating member 12; as shown in diagram a. Figure 4 As shown in b, when the bent portion 112 and the second magnet 123 are attracted to each other, the main body portion 111 is located in the mating cavity 121 so that the pull ring 1111 on the main body portion 111 is hidden inside the second mating member 12.

[0059] like Figure 4 In Figure 4 c and Figure 4d shows a structure where the bending angle θ between the main body 111 and the bent portion 112 is less than 90 degrees. If the bending angle θ is set to less than 90 degrees, the thickness of the mating cavity 121 can be reduced compared to... Figure 4 a and Figure 4 The mating cavity 121 shown in b is thinner, facilitating the design of thinner components. For example... Figure 4 As shown in c, when the bent portion 112 and the first magnet 122 are attracted to each other, the main body portion 111 extends out of the mating hole 1211 so that the pull ring 1111 on the main body portion 111 is exposed outside the second mating member 12; as Figure 4 As shown in d, when the bent portion 112 and the second magnet 123 are attracted to each other, the main body portion 111 is located in the mating cavity 121 so that the pull ring 1111 on the main body portion 111 is hidden inside the second mating member 12.

[0060] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0061] This application provides a strap fitting assembly 10 and a head-mounted device 100. The strap fitting assembly 10 is applied to the head-mounted device 100. The strap fitting assembly 10 includes a first fitting member 11 and a second fitting member 12. The first fitting member 11 has a main body portion 111 and a bent portion 112. A pull ring 1111 is provided at one end of the main body portion 111 away from the bent portion 112. The pull ring 1111 is used for detachable connection with the top strap 40 of the head-mounted device 100. The second fitting member 12 includes a fitting cavity 121, a first magnet 122 and a second magnet 123. The first magnet is provided at the top of the fitting cavity 121. 122, a second magnet 123 is provided at the bottom of the mating cavity 121, and a mating hole 1211 is provided at the top. The main body 111 is inserted into the mating hole 1211, and the bent part 112 is movably disposed between the first magnet 122 and the second magnet 123. When the bent part 112 and the first magnet 122 are attracted to each other, the main body 111 extends out of the mating hole 1211 so that the pull ring 1111 is exposed outside the second mating member 12. When the bent part 112 and the second magnet 123 are attracted to each other, the main body 111 is located in the mating cavity 121 so that the pull ring 1111 is hidden inside the second mating member 12. In this embodiment, the use of the bending portion 112 in the first mating part 11 and the magnet in the second mating part 12 enables the quick assembly and disassembly of the top strap 40 of the head-mounted device 100. When the top strap 40 is needed, the pull ring 1111 is exposed due to the attraction between the bending portion 112 and the first magnet 122, making it convenient for the user to thread the top strap 40 onto the pull ring 1111. When the top strap 40 is not needed, the user removes the top strap 40 from the pull ring 1111, and the pull ring 1111 is hidden due to the attraction between the bending portion 112 and the second magnet 123, without affecting the aesthetics of the head-mounted device 100. This allows for quick assembly and disassembly of the top strap 40 without affecting the appearance of the device, reducing user operating costs and improving assembly and disassembly efficiency.

[0062] For details, please refer to Figures 5 to 8 This application also provides a head-mounted device. The head-mounted device 100 includes a strap-fitting assembly 10, a device body 20, a battery compartment assembly 30, a top strap 40, and side straps 50. For the specific structure of the strap-fitting assembly 10, please refer to... Figures 1 to 4 .

[0063] The device body 20 and the battery compartment assembly 30 are arranged opposite to each other. The side straps 50 are symmetrically installed on both sides of the device body 20 and the battery compartment assembly 30. The strap fitting assembly 10 is installed on the battery compartment assembly 30. The first end of the top strap 40 is detachably connected to the top of the device body 20, and the second end of the top strap 40 is detachably connected to the pull ring 1111 on the first fitting part 11 in the strap fitting assembly 10.

[0064] like Figure 1 , Figure 5 , Figure 7 and Figure 8 As shown, when the user needs to use the top strap 40, they can manually pull out the pull ring 1111. At this time, the bent portion 112 at the end away from the pull ring 1111 is attracted to the first magnet 122 (as shown). Figure 1 As shown), the pull ring 1111 is exposed due to the attraction between the bent portion 112 and the first magnet 122 (as shown). Figure 5 , Figure 7 and Figure 8 As shown, this allows the user to easily thread the top strap 40 onto the pull ring 1111. After threading the top strap 40 onto the pull ring 1111, the user can use the top strap normally.

[0065] like Figure 2 and Figure 6 As shown, when the user does not need to use the top strap 40, after removing the top strap 40 from the pull ring 1111, the user presses down on the pull ring 1111. At this time, the bent portion 112 at the end away from the pull ring 1111 is attracted to the second magnet 123 (as shown). Figure 2 As shown), the pull ring 1111 is almost completely hidden in the first mating part 12. Only because part of the edge of the pull ring 1111 protrudes beyond the first mating part 12, the pull ring 1111 can be hidden by the attraction between the bent part 112 and the second magnet 123 (as shown). Figure 6 As shown, it does not affect the aesthetics of the head-mounted device 100, allows for quick assembly and disassembly of the top strap 40, and has a simple and highly reliable structure. At the same time, it does not affect the aesthetics of the device after disassembly, reducing user operating costs and improving assembly and disassembly efficiency.

[0066] For example, the main body 20 of the device may include two lens barrels, integrated circuits, memory, processor, display, electronic circuits, sensors, input units, output units, heat sinks, etc.

[0067] For example, the main body 20 of the device also includes an interpupillary distance adjuster for adjusting the interpupillary distance between the two lens barrels. The main body 20 also includes an interpupillary distance detector electrically connected to the interpupillary distance adjuster, which detects the interpupillary distance of the human eye. Based on the interpupillary distance detected by the interpupillary distance detector, the interpupillary distance adjuster controls a drive unit within it to move the two lens barrels in the same or opposite directions to adjust the interpupillary distance between the two lens barrels to match the interpupillary distance of the human eye. The interpupillary distance detector may include a camera and a processing unit. The camera is mounted on the two lens barrels or on the housing of the main body 20. The camera is used to acquire eye images, and the processing unit is used to perform image processing on the eye images according to a visual algorithm to detect the interpupillary distance of the human eye. The main body 20 also includes a Hall sensor electrically connected to the interpupillary distance adjuster. The Hall sensor is located within the housing of the main body 20. At least one of the two lens barrels has a magnetic element, and the Hall sensor detects the interpupillary distance between the two lens barrels by sensing the strength of the magnetic field of the magnetic element.

[0068] For example, the main body 20 of the device also has a cover that covers the outer walls of the two lens barrels, and a nose pad is formed on the cover. When worn, the edge of the cover can conform to the user's face, and the nose pad can be used to place the main body 20 of the device on the user's nose. For example, the cover may also have a gasket to prevent the cover from causing friction from hard contact with the user's face. For example, the nose pad may also have a nose cushion to prevent friction from hard contact between the main body 20 of the device and the user's nose. For example, the gasket and nose cushion may be made of soft materials such as sponge or silicone.

[0069] For example, the battery compartment assembly 30 contains at least one set of batteries and is electrically connected to the device body 20 to supply power to the device body 20. In the wearing state, the battery compartment assembly 30 is located behind the user's head, and the device body 20 is located in front of the user's head. The battery compartment assembly 30 and the device body 20 are secured to the user's head by side straps 50. Additionally, a strap fitting assembly 10 is mounted on the battery compartment assembly 30. The first end of the top strap 40 is detachably connected to the top of the device body 20, and the second end of the top strap 40 is detachably connected to a pull ring 1111 on the first fitting member 11 in the strap fitting assembly 10.

[0070] For example, a heat dissipation component, such as a cooling fan or heat sink, can be installed inside the main body 20 and / or the battery compartment assembly 30.

[0071] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0072] This application provides a head-mounted device 100, which includes a strap assembly 10, a device body 20, a battery compartment assembly 30, a top strap 40, and side straps 50. The strap assembly 10 includes a first fitting member 11 and a second fitting member 12. The first fitting member 11 has a main body portion 111 and a bent portion 112. A pull ring 1111 is provided at one end of the main body portion 111 away from the bent portion 112, and the pull ring 1111 is used for detachable connection with the top strap 40 of the head-mounted device 100. The second fitting member 12 includes a fitting cavity 121, a first magnet 122, and a second magnet 123. The top end is provided with a first magnet 122, the bottom end of the mating cavity 121 is provided with a second magnet 123, and the top end is also provided with a mating hole 1211. The main body 111 is inserted into the mating hole 1211, and the bent part 112 is movably disposed between the first magnet 122 and the second magnet 123. When the bent part 112 and the first magnet 122 attract each other, the main body 111 extends out of the mating hole 1211 so that the pull ring 1111 is exposed outside the second mating member 12. When the bent part 112 and the second magnet 123 attract each other, the main body 111 is located inside the mating cavity 121 so that the pull ring 1111 is hidden inside the second mating member 12. The device body 20 and the battery compartment assembly 30 are arranged opposite to each other. The side straps 50 are symmetrically installed on both sides of the device body 20 and the battery compartment assembly 30. The strap fitting assembly 10 is installed on the battery compartment assembly 30. The first end of the top strap 40 is detachably connected to the top of the device body 20, and the second end of the top strap 40 is detachably connected to the pull ring 1111 on the first fitting part 11 in the strap fitting assembly 10. In this embodiment, the use of the bending portion 112 in the first mating part 11 and the magnet in the second mating part 12 enables the quick assembly and disassembly of the top strap 40 of the head-mounted device 100. When the top strap 40 is needed, the pull ring 1111 is exposed due to the attraction between the bending portion 112 and the first magnet 122, making it convenient for the user to thread the top strap 40 onto the pull ring 1111. When the top strap 40 is not needed, the user removes the top strap 40 from the pull ring 1111, and the pull ring 1111 is hidden due to the attraction between the bending portion 112 and the second magnet 123, without affecting the aesthetics of the head-mounted device 100. This allows for quick assembly and disassembly of the top strap 40 without affecting the appearance of the device, reducing user operating costs and improving assembly and disassembly efficiency.
