Description

Technical Field

[0001] This application relates to the field of near-eye displays, and more particularly to headbands and head-mounted display devices. Background Technology

[0002] In recent years, head-mounted display devices have become increasingly popular, and their wearing comfort and stability have become key factors affecting user experience. Traditional headbands typically use rigid connections or simple strap designs, which can easily cause pressure or loosening after prolonged wear, affecting the user experience.

[0003] Therefore, it is necessary to provide a headband and head-mounted display device to solve the problem of poor comfort in existing head-mounted display devices. Utility Model Content

[0004] This application provides a headband and a head-mounted display device to solve the problem of poor comfort in existing head-mounted display devices.

[0007] The first headband assembly is rotatably connected to the connecting arm and is used to contact the back of the user's head; the second headband assembly is rotatably connected to the connecting arm and is used to contact the forehead of the user.

[0008] The rotation axis of the first headband assembly is closer to the second end of the connecting arm than the rotation axis of the second headband assembly.

[0009] By adopting the above technical solution, the headband is used to fix the display device body to the user's head. The headband includes a connecting arm, a first headband assembly, and a second headband assembly. The connecting arm adopts a front-to-back offset pivot design.

[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] As described in the background section, in the field of head-mounted display devices, including Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR), the headband is a core component for ensuring stable wear of the head-mounted display device. It primarily serves to balance the weight of the device and adapt to the user's head shape. The headband typically consists of connecting arms, a top-mounted fixation component, and a back-mounted fixation component. Among these, the connecting arms, as a key component for force transmission, directly affect the wearing comfort of the head-mounted display device.

[0053] Traditional headbands often use coaxial rotation for their front and rear fixation components, resulting in uneven force distribution. Specifically, the rotation axes of the top and back fixation components coincide or are too close, failing to create effective force couple balance. Consequently, the weight of the head-mounted display device relies primarily on the pressure from the face.

[0054] Therefore, there is an urgent need for a headband that can optimize force distribution and improve comfort. To solve the technical problems of uneven force distribution and poor comfort in traditional headbands, this application provides a headband for fixing a display device to a user's head. The headband includes a connecting arm, a first headband assembly, and a second headband assembly. The connecting arm adopts a front-to-back offset pivot design. When wearing a head-mounted display device with a headband, the first headband assembly contacts the user's forehead area, and the second headband assembly contacts the user's back of the head area. The first headband assembly and the second headband assembly can form a spatially complementary constraint relationship.

[0055] In practice, the rotation axis of the first headband assembly is located behind the rotation axis of the second headband assembly, ensuring a reasonable lever arm ratio between the restraint force of the first headband assembly on the back of the head and the restraint force of the second headband assembly on the forehead. This staggered arrangement allows the weight of the head-mounted display device to be transferred to the forehead via the connecting arm and the second headband assembly, and to the back of the head via the connecting arm and the first headband assembly, forming a stable three-point support system and reducing the pressure of the display device on the user's face.

[0056] Understandably, compared to existing headband solutions that use coaxial connections or simple straps, the headband in this embodiment, through its staggered pivot design, optimizes the weight distribution of the head-mounted display device while maintaining a simple structure. This avoids the problem of excessive facial pressure in traditional solutions, ensures wearing stability, and significantly improves comfort during extended use.

[0063] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0064] See Figures 1 to 11 This application provides a headband, which may include a connecting arm 200, a first headband assembly 300, and a second headband assembly 400.

[0065] The first end of the connecting arm 200 can be used to connect to the display device body 100, realizing the effective transfer and distribution of the weight of the head-mounted display device. The second end of the connecting arm 200 can extend backward, reasonably guiding the load generated by the display device body 100 to the front forehead area and the back of the head area, forming a force transmission path between the front display device body 100 and the headband assembly.

[0066] There are several ways to connect the connecting arm 200 to the display device body 100. For example, the connecting arm 200 can be connected to the display device body 100 via a pivot structure, allowing the connecting arm 200 to rotate relative to the display device body 100 within a certain angle range, thus improving wearability. In another embodiment, the connecting arm 200 can be fixedly connected to the display device body 100, adapting to different head shapes through its own elastic deformation.

[0067] In one possible implementation, the first headband assembly 300 can be rotatably connected to the connecting arm 200. This rotatable connection allows for adaptive adjustment of the contact angle and pressure distribution between the first headband assembly 300 and the user's head area, enabling the first headband assembly 300 to automatically adjust its posture according to the user's head shape, thus improving wearing comfort while ensuring support stability.

[0068] The first headband assembly 300 and the connecting arm 200 can be rotatably connected by a variety of mechanical structures such as hinges, ball joints or elastic shafts, which can ensure rotational freedom while providing appropriate damping to maintain a stable posture.

[0069] The first headband assembly 300 can be used to contact the back of the user's head, converting the weight of the head-mounted display device into a uniformly distributed pressure on the back of the head, dispersing the force exerted by the head-mounted display device on the back of the head, and working together with the second headband assembly 400 to form a stable three-point support system.

[0070] The first headband assembly 300 can be configured in several ways. For example, the first headband assembly 300 can adopt an arc-shaped band structure with a radius of curvature matching the contour of the back of the human head, and a flexible contact pad can be provided in the middle to increase the contact area. In another embodiment, the first headband assembly 300 can adopt a split design, consisting of multiple independently adjustable support units, which can better adapt to the differences in head shapes among different users.

[0071] In one possible implementation, the second headband assembly 400 can be rotatably connected to the connecting arm 200. This rotatable connection allows for automatic adjustment of the contact angle based on the curvature of the user's forehead, achieving a dynamic balance between fit and support.

[0072] The second headband assembly 400 and the connecting arm 200 can be rotatably connected by a variety of mechanical structures such as hinges, ball joints or elastic shafts, which can ensure rotational freedom while providing appropriate damping to maintain a stable posture.

[0073] The second headband assembly 400 can be used to contact the user's forehead area, balance the forward tilting torque of the head-mounted display device, and form a cooperative force-bearing system with the first headband assembly 300 at the back of the head.

[0074] The second headband assembly 400 can be configured in various ways. For example, the second headband assembly 400 can adopt an arc-shaped band structure with a radius of curvature matching the contour of the forehead region, and a flexible contact pad can be provided in the middle to increase the contact area. In another embodiment, the second headband assembly 400 can adopt a split design, consisting of multiple independently adjustable support units, which can better adapt to the differences in head shapes among different users.

[0075] Furthermore, in the selection of materials for the first headband assembly 300 and the second headband assembly 400, composite materials with gradient hardness characteristics can be used. Specifically, a softer material can be used in the central contact area to improve comfort, while a harder material can be used in the edge area to ensure structural strength.

[0076] Furthermore, the first headband assembly 300 and the second headband assembly 400 can integrate a length adjustment device. Specifically, a sliding rail, Velcro, or elastic telescopic structure can be used to accommodate different user head circumference sizes.

[0077] In addition, ventilation holes or heat dissipation channels may be provided on the surfaces of the first headband assembly 300 and the second headband assembly 400 to improve breathability during prolonged wear. The parts of the first headband assembly 300 and the second headband assembly 400 that come into contact with the head may also be designed as detachable structures for easy cleaning and replacement.

[0078] When wearing the headband, the user first positions the display device 100 in front of their eyes. At this time, the connecting arm 200 naturally extends backward. Its specific extension angle and length design can ensure that the first headband assembly 300 and the second headband assembly 400 can accurately correspond to the target contact areas of the back of the head and the forehead.

[0079] The first headband assembly 300, through its rotatable connection characteristics, automatically conforms to the contours of the back of the user's head during wear. When pressure is applied to the head, the first headband assembly 300 adaptively adjusts its angle around the rotation axis of the connecting arm 200, ensuring that its central area makes surface contact with the occipital bone. This dynamic conformation mechanism ensures that the force is evenly distributed in the back of the head. At the same time, the extensions on both sides of the first headband assembly 300 naturally wrap around the sides of the head, forming a stable embracing effect.

[0080] The second headband assembly 400 acts synchronously on the forehead area, and its rotatable connection design allows the second headband assembly 400 to automatically adjust its posture according to the curvature of the forehead area. When worn, the second headband assembly 400 contacts the upper part of the forehead area with appropriate pressure, and the pressure is evenly transmitted to the area above the brow bone through the middle.

[0081] The second headband assembly 400 and the first headband assembly 300 form a front-to-back constraint relationship, jointly constructing a stable three-point support system. The contact pressure in the forehead area and the constraint force in the back of the head area are balanced by the connecting arm 200, effectively counteracting the forward tilting torque of the head-mounted display.

[0082] Once worn, the weight of the display device 100 is distributed to the first headband assembly 300 and the second headband assembly 400 via the connecting arm 200, significantly reducing facial pressure. The adaptive adjustment of the first headband assembly 300 and the second headband assembly 400 ensures even pressure distribution, avoiding localized discomfort. The rotational connection mechanism provides the freedom to adapt the first headband assembly 300 and the second headband assembly 400 to different head shapes, maintaining a stable fit. The entire system maintains a stable wearing state during dynamic use; when the user's head moves, each component automatically fine-tunes its position through the rotational connection, continuously maintaining optimal force distribution.

[0083] In one possible implementation, the rotation axis at the connection between the first headband assembly 300 and the connecting arm 200 and the rotation axis at the connection between the second headband assembly 400 and the connecting arm 200 can be located at different positions and arranged differently along the length of the connecting arm 200.

[0084] Specifically, the rotation axis of the first headband assembly 300 can be close to the second end of the connecting arm relative to the rotation axis of the second headband assembly 400.

[0085] The rotation axis of the second headband assembly 400 on the front side mainly bears the weight transmission of the front part of the display device body 100, while the rotation axis of the first headband assembly 300 on the rear side is responsible for balancing the restraint force in the back area of ​​the head. The axial distance between the two rotation axes can form an effective lever arm length, enabling the first headband assembly 300 and the second headband assembly 400 to work together to build a stable torque balance system, so that the weight of the display device body 100 can be more reasonably distributed.

[0086] Differentiated arrangement of the rotation axis can improve the wearing effect in several ways: First, it can increase the distance between the front and rear restraint forces, forming a more stable support base; second, it can allow the first headband assembly 300 and the second headband assembly 400 to independently adapt to different head curvatures, improving the fit; third, by optimizing the lever arm length ratio, the pressure distribution in the front and rear areas can be precisely controlled; and fourth, it can avoid the size increase caused by the intersection of the first headband assembly 300 and the second headband assembly 400, reducing pressure on the user's ear area.

[0087] During dynamic use, this staggered rotating shaft design allows the front and rear components to adjust themselves according to the head's movement, avoiding mutual interference and maintaining a continuous and stable fit.

[0088] In some embodiments, the connecting arm 200 may include a preauricular portion 230 and a postauricular portion 240 connected to each other. The preauricular portion 230, as the front section of the connecting arm 200, can connect the display device body 100 and the second headband assembly 400, and its extension path passes in front of the auricle, forming support for the front of the head-mounted display. The postauricular portion 240 can serve as the rear extension of the connecting arm 200, transitioning to the rear of the auricle, providing a stable mounting base for the first headband assembly 300.

[0089] Specifically, according to Section 5.2.3 of IEEE Std 2806.1-2022 "Standard for Augmented Reality Learning Experience Models" (hereinafter referred to as the Standard), the anatomical boundary in front of the ear can be defined as follows: with the tragus as the posterior boundary reference, extending anteriorly to the surface projection area of ​​the zygomatic arch, with the upper boundary being the lower edge of the temporal line, and the lower boundary reaching the horizontal plane of the lobuleattachment.

[0090] The structural boundaries behind the ear are defined according to Section 5.2.4 of the standard, and can be specifically defined as follows: the anterior boundary is the projection point of the posterior cruciate of the helix on the body surface, extending posteriorly to the posterior edge of the mastoid area, the upper boundary reaches the superior nuchal line, and the lower boundary reaches the lower edge of the retroauricular sulcus.

[0091] See Figure 3 When wearing a head-mounted display device, the part of the connecting arm 200 that fits in front of the ear can be called the preauricular part 230, and the part of the connecting arm 200 that fits behind the ear can be called the postauricular part 240. Due to individual differences, the position of the human ear is not completely uniform, and the division between the preauricular and postauricular parts is relative in practical applications. The front and rear parts of the connecting arm 200 can roughly correspond to the preauricular and postauricular areas.

[0092] By dividing the front part 230 and the back part 240 of the ear in the above manner, the entire auricle structure can be left empty as an independent unit, forming a natural clearance space, eliminating the risk of pressure on the ear tissue, and can be highly consistent with the position of the main weight-bearing areas of the head (zygomatic arch and occipital region), so that the weight of the head-mounted display device can be optimally distributed to the bone parts suitable for weight-bearing.

[0093] Alternatively, the division between the anterior part 230 and the posterior part 240 can be based on the apex of the auricle, with the area in front of the apex of the auricle defined as the anterior part 230 and the area behind the apex of the auricle defined as the posterior part 240.

[0094] By dividing the front ear portion 230 and the back ear portion 240 in the aforementioned manner, a more compact layout for the head-mounted display device can be achieved. By incorporating part of the auricle area into the support structure, the force transmission path is shortened, and the overall rigidity is enhanced. The front ear portion 230 can fully utilize the natural curvature of the front side of the auricle as a support reference, improving the stability of the forehead area constraint; the back ear portion 240, on the other hand, utilizes the morphological characteristics of the back side of the auricle to create a more closely fitting coverage effect for the back of the head. At the same time, because the support surface is closer to the center of gravity of the head, it helps to reduce the inertial torque when the head-mounted display device is worn.

[0095] Dividing the connecting arm 200 into a pre-ear portion 230 and a post-ear portion 240 enables a reasonable distribution of the weight of the display device body 100, allowing the load generated by the display device body 100 to be transferred to different areas of the head. The pre-ear portion 230, as the front support structure of the connecting arm 200, can bear the weight transfer of the front of the display device body 100, while the post-ear portion 240, as the rear extension structure of the connecting arm 200, can provide rearward constraint.

[0096] In one possible implementation, the rotation axis of the first headband assembly 300 can be located behind the ear 240, and the rotation axis of the second headband assembly 400 can be located in front of the ear 230. By differentiating the positions of the rotation axes along the length of the connecting arm 200, a front-to-back partition constraint system can be formed, allowing the weight of the head-mounted display device to be more rationally distributed to different areas of the head.

[0097] The rotation axis of the first headband assembly 300 is located behind the ear 240, which allows the restraining force to be mainly applied to areas with strong load-bearing capacity, such as the occipital protuberance. The rotation axis of the second headband assembly 400 is located in front of the ear 230, which can optimize the pressure distribution of the contact surface with the forehead area and avoid excessive pressure on sensitive areas such as the temples.

[0098] In one possible implementation, the rotation axis of the first headband assembly 300 can be located at the rear end of the connecting arm 200. Positioning the rotation axis of the first headband assembly 300 at the end region of the connecting arm 200 allows the first headband assembly 300 to be adjusted within a wide range of angles to accommodate different user head circumferences.

[0099] Meanwhile, the rotation axis of the second headband assembly 400 can be located in the front region of the connecting arm 200, and the two rotation axes maintain a specific spacing ratio along the extension direction of the connecting arm 200.

[0100] Preferably, in the extending direction of the connecting arm 200, the ratio of the distance between the rotation axis of the first headband assembly 300 and the rotation axis of the second headband assembly 400 to the length of the connecting arm 200 can be greater than or equal to 0.5 and less than or equal to 0.9.

[0101] When the ratio of the distance between the rotation axis of the first headband assembly 300 and the rotation axis of the second headband assembly 400 to the total length of the connecting arm 200 is within the range of 0.5 to 0.9, an optimal lever arm balance can be established between the front and rear constraint forces. A lower limit of 0.5 ensures sufficient lever arm length, allowing the front and rear constraint forces to form an effective torque to balance the overturning moment of the display device body 100; an upper limit of 0.9 ensures structural compactness and prevents the connecting arm 200 from being too long, thus affecting the overall coordination of the head-mounted display device. While ensuring that the support force in the forehead area and the constraint force in the back of the head can form an effective torque balance, it avoids both insufficient torque due to a too small ratio and structural redundancy due to a too large ratio.

[0102] Of course, in specific implementation, this ratio can be optimized according to the weight distribution and size specifications of different head-mounted displays. For example, the ratio of the distance between the rotation axis of the first headband assembly 300 and the rotation axis of the second headband assembly 400 to the length of the connecting arm 200 can be set in any range of 0.5-0.6, 0.6-0.7, 0.7-0.8 and 0.8-0.9.

[0103] In one possible implementation, at the connection between the first headband assembly 300 and the connecting arm 200 (i.e., the rotation axis of the first headband assembly 300), the first headband assembly 300 can be located outside the connecting arm 200. At this connection, the connection point of the first headband assembly 300 can be configured to be located in the outer region of the cross-section of the connecting arm 200, forming an outwardly eccentric connection structure. This locally outer arrangement can optimize the torque transmission characteristics of the connection point while maintaining a compact overall structure.

[0104] The end of the connecting arm 200 may be provided with an outwardly extending support structure. The rotation axis of the first headband assembly 300 can be mounted on this support structure, causing its rotation center to be offset relative to the main axis of the connecting arm 200 by a predetermined amount, which depends on the size of the support structure. This connection method allows the first headband assembly 300 to obtain an additional lever arm length at the connection point, enhancing its coverage of the posterior head region.

[0105] Alternatively, at the connection point between the second headband assembly 400 and the connecting arm 200 (i.e., the rotation axis of the second headband assembly 400), the second headband assembly 400 can be located inside the connecting arm 200. At this connection point, the connection of the second headband assembly 400 can be configured to be located in the inner region of the cross-section of the connecting arm 200, forming an inwardly eccentric connection structure. This locally inner arrangement optimizes the direction of the support force on the forehead region while ensuring structural integrity.

[0106] The front section of the connecting arm 200 may be provided with an inwardly recessed mounting groove, in which the rotation axis of the second headband assembly 400 can be accommodated, causing its rotation center to shift inward relative to the main axis of the connecting arm 200. This connection method allows the second headband assembly 400 to obtain a fulcrum position closer to the midline of the face at the connection point, which is beneficial for forming a more uniform pressure distribution in the forehead area.

[0107] Alternatively, at the connection between the first headband assembly 300 and the connecting arm 200, the first headband assembly 300 may be located outside the connecting arm 200, and at the connection between the second headband assembly 400 and the connecting arm 200, the second headband assembly 400 may be located inside the connecting arm 200.

[0108] The connection points of the first headband assembly 300 and the second headband assembly 400 with the connecting arm 200 employ differentiated orientations to form an optimized force transmission network. The outer connection of the first headband assembly 300 is achieved through an extended support structure at the rear end of the connecting arm 200, with its rotation axis offset outward relative to the main axis of the connecting arm 200. This arrangement enhances the leverage effect of the restraint force in the posterior head region. Simultaneously, the inner connection of the second headband assembly 400 is achieved through a recessed mounting groove at the front end of the connecting arm 200, with its rotation axis offset inward relative to the main axis of the connecting arm 200. This design optimizes the direction of the support force in the forehead region. The differentiated arrangement of the two connection points creates a complementary relationship in space, ensuring optimal realization of their respective functions while avoiding structural interference.

[0109] In one possible implementation, at the connection between the first headband assembly 300 and the connecting arm 200, the first headband assembly 300 may be located inside the connecting arm 200, or extend through the inner and outer sides of the connecting arm 200.

[0110] At the connection between the second headband assembly 400 and the connecting arm 200, the second headband assembly 400 may be located on the outside of the connecting arm 200, or extend through the inside and outside of the connecting arm 200.

[0111] In one possible implementation, the first headband assembly 300 may include a first headband 310 and a first contact pad 320. The first headband 310 may be the main support component of the first headband assembly 300, and may be a strip structure with a certain rigidity. Its two ends are connected to rotating structures, and a mounting opening for the first contact pad 320 may be provided in the middle for fixing the first contact pad 320.

[0112] The first contact pad 320 can be located in the middle of the first headband 310, so that it can accurately correspond to the main contact area of ​​the back of the user's head and fit against the back of the user's head.

[0113] The first contact pad 320 can be detachably or securely installed in the middle of the first headband 310 using methods such as snaps, magnetic attachment, or adhesive. Its contact surface can be designed as an arc-shaped surface that conforms to the physiological curvature of the back of the head. The combination design of the first contact pad 320 and the first headband 310 allows for adaptation and adjustment to different user head shapes, such as optimizing the fit by replacing the first contact pad 320 with different curvatures or hardness.

[0114] In a preferred embodiment, the longitudinal dimension of the first contact pad 320 can be configured to cover the main weight-bearing area from the external occipital protuberance to the base of the skull.

[0115] In one possible implementation, the second headband assembly 400 may include a second headband 410 and a second contact pad 420. The second headband 410 may be the main support component of the second headband assembly 400, and may be a strip structure with a certain rigidity, with rotating structures connected at both ends, and a mounting opening for the second contact pad 420 provided in the middle for fixing the second contact pad 420.

[0116] The second contact pad 420 can be located in the middle of the second headband 410, so that it can accurately correspond to the appropriate weight-bearing part above the user's brow bone.

[0117] The second contact pad 420 can be detachably or securely installed in the middle of the second headband 410 using methods such as snaps, magnetic attachment, or adhesive. Its contact surface can be designed as an arc-shaped surface that conforms to the physiological curvature of the forehead area. The combination design of the second contact pad 420 and the second headband 410 allows for adaptation and adjustment to different user head shapes, such as optimizing the fit by replacing the second contact pad 420 with different curvatures or hardness.

[0118] In one possible implementation, the lengths of the first headband 310 and the second headband 410 are adjustable. The lengths of the first headband 310 and the second headband 410 can be adjusted via a length adjustment mechanism, which can be integrated into the first headband assembly 300 and the second headband assembly 400, allowing the user to adjust according to individual head circumference, ensuring that the restraint forces in the posterior head region and the frontal head region are always maintained at their optimal levels.

[0119] The length adjustment mechanism can be implemented in various ways. For example, a combination of slide rail and ratchet mechanism can be used, with adjustable sections that can slide relative to each other at both ends of the first head belt 310 and the second head belt 410, and discrete length adjustment can be achieved by ratchet positioning; another implementation can utilize an elastic telescopic structure, such as a continuous adjustment mechanism with built-in springs or elastic bands, to achieve stepless length change; a segmented connection design can also be used, and length adjustment can be achieved by changing the position of the connection point.

[0120] The length adjustment mechanism can be located in the middle or at the end of the first headband 310 and the second headband 410, and is preferably equipped with a visual scale mark or tactile feedback device to facilitate the user to accurately grasp the adjustment amount.

[0121] In one possible implementation, the hardness of the first contact pad 320 and the hardness of the second contact pad 420 can be different. Based on the different anatomical characteristics and load-bearing requirements of the front and rear head regions, the first contact pad 320 and the second contact pad 420 can adopt differentiated hardness configurations.

[0122] Specifically, the first contact pad 320 can be made of a medium-firm cushioning material to ensure stable support for the occipital region. The second contact pad 420 can be made of a relatively soft elastic material to accommodate the thinner and more sensitive skin in the forehead area.

[0123] Differences in hardness can be achieved through material selection, such as using high-density memory foam or rigid silicone for the first contact pad 320, and low-resilience foam or gel material for the second contact pad 420; or through structural design, such as setting a thicker support base layer for the first contact pad 320, and adopting a porous pressure-reducing structure for the second contact pad 420.

[0124] In one possible implementation, the first contact pad 320 may include multiple first buffer sections, with at least two of the first buffer sections having different hardness. The first contact pad 320 may be divided into multiple first buffer sections along its length. The first buffer section in the middle corresponds to the main weight-bearing area of ​​the forehead and may use a low-hardness material to improve comfort. The hardness of the first buffer sections extending to both sides may gradually increase to enhance edge support. The hardness transition between the various first buffer sections may be achieved through material gradients or structural transitions.

[0125] Alternatively, the second contact pad 420 may include multiple second buffer sections, with at least two second buffer sections having different hardness. The second contact pad 420 may be divided into multiple second buffer sections along its length. The second buffer section in the middle corresponds to the main weight-bearing area at the back of the head and may use a low-hardness material to improve comfort. The hardness of the second buffer sections extending to both sides may gradually increase to enhance edge support. The hardness transition between the various second buffer sections can be achieved through material gradients or structural transitions.

[0126] Alternatively, the first contact pad 320 may include multiple first cushioning portions, at least two of which have different hardness, and the second contact pad 420 may include multiple second cushioning portions, at least two of which have different hardness. The first contact pad 320 may be divided into multiple first cushioning portions along its length. The central first cushioning portion corresponds to the main weight-bearing area of ​​the forehead and may use a low-hardness material to improve comfort; the hardness of the first cushioning portions extending to both sides may gradually increase to enhance edge support. The second contact pad 420 may be divided into multiple second cushioning portions along its length. The central second cushioning portion corresponds to the main weight-bearing area at the back of the head and may use a low-hardness material to improve comfort; the hardness of the second cushioning portions extending to both sides may gradually increase to enhance edge support.

[0127] In one possible implementation, the first contact pad 320 may include multiple first buffer layers, with at least two first buffer layers having different hardness. The first contact pad 320 can be divided into multiple first buffer layers from the outer connecting surface to the inner contact surface, with the material hardness decreasing from the outside to the inside. The outer first buffer layer can be made of a high-hardness material to ensure structural stability, while the inner first buffer layer can be made of a low-hardness material to directly contact the forehead, improving comfort. The layered gradient hardness design allows pressure to gradually transition from the rigid connecting structure to the soft contact surface, ensuring support strength while reducing local pressure.

[0128] Alternatively, the second contact pad 420 may include multiple second buffer layers, with at least two second buffer layers having different hardness. The second contact pad 420 can be divided into multiple second buffer layers from the outer connecting surface to the inner contact surface, with the material hardness decreasing from the outside to the inside. The outer second buffer layer can be made of a high-hardness material to ensure structural stability, while the inner second buffer layer can be made of a low-hardness material that directly contacts the back of the head to improve comfort. The layered gradient hardness design allows pressure to gradually transition from the rigid connection structure to the soft contact surface, ensuring support strength while reducing localized pressure.

[0129] Alternatively, the first contact pad 320 may include multiple first buffer layers, at least two of which have different hardness, and the second contact pad 420 may include multiple second buffer layers, at least two of which have different hardness. The first contact pad 320 can be divided into multiple first buffer layers from the outer connecting surface to the inner contact surface, with the material hardness decreasing from the outside to the inside. The outer first buffer layer can be made of a high-hardness material to ensure structural stability, while the inner first buffer layer can be made of a low-hardness material to directly contact the forehead, improving comfort. The second contact pad 420 can be divided into multiple second buffer layers from the outer connecting surface to the inner contact surface, with the material hardness decreasing from the outside to the inside. The outer second buffer layer can be made of a high-hardness material to ensure structural stability, while the inner second buffer layer can be made of a low-hardness material to directly contact the back of the head, improving comfort.

[0130] This application provides a head-mounted display device, including a display device body 100 and a headband as described above.

[0131] The display device body 100 can serve as the core functional carrier, mainly undertaking functions such as image display and data processing. The display device body 100 can be connected to a connecting arm 200, and the display device body 100 is mechanically connected to the headband through the connecting arm 200.

[0132] The number of connecting arms 200 can be two. The two connecting arms 200 can include a first connecting arm 210 and a second connecting arm 220, which can be two independent and mirror-symmetrical support structures. The dual connecting arm configuration can form the main support frame of the head-mounted display device, primarily used to establish a stable force transmission path between the display device body 100 and the head, while simultaneously achieving a balanced weight distribution on both sides of the head-mounted display device.

[0133] The display device body 100 may be provided with a first cable 110 and a second cable 120. The first end of the first cable 110 may be connected to the display device body 100, and the second end of the first cable 110 may be routed through the first connecting arm 210 to the rear side of the first connecting arm 210.

[0134] The first end of the second cable 120 can be connected to the display device body 100, and the second end of the second cable 120 can be routed through the second connecting arm 220 to the rear side of the second connecting arm 220.

[0135] The first cable 110 and the second cable 120 can be symmetrically positioned at the outlet position on the rear side of the connecting arm 200, with sufficient spacing between them to avoid interference.

[0136] The first cable 110 and the second cable 120 can be configured with standardized interface modules at the end positions on the rear side of the connecting arm 200 to facilitate connection with external devices.

[0137] In this way, the split cable arrangement can solve the problems of wire tangling and space occupation caused by traditional centralized cabling. At the same time, the symmetrical arrangement can balance the weight distribution on both sides, avoiding discomfort caused by uneven load. Furthermore, the rear cable exit design can reduce the interference of cables with the user's line of sight.

[0138] Specifically, the cable routing path can employ various protective structures. For example, a dedicated cable channel can be set inside the first connecting arm 210 and the second connecting arm 220 to form a closed wiring environment, or guide grooves can be opened on the surfaces of the first connecting arm 210 and the second connecting arm 220 to achieve open management in conjunction with the cable bundling device.

[0139] like Figure 6 As shown, in one possible implementation, the first connecting arm 210 may include a first support portion 211 and a first contact portion 212 located inside the first support portion 211. At least a portion of the first cable 110 may be located between the first support portion 211 and the first contact portion 212.

[0140] The first support portion 211 can serve as the outer skeleton of the connecting arm 200, and its cross-sectional shape can be set to U-shaped or C-shaped to form a natural cable accommodating space. The first contact portion 212 can serve as an inner component, and is fixed to the inside of the support portion by means of snap-fit, bonding, or integral molding, forming a continuous cable channel between the two. The first cable 110 can be arranged in this interlayer space, and its direction can be arranged in a straight line along the extension direction of the connecting arm 200.

[0141] The first contact portion 212, serving as a functional interface that directly contacts the user's head, can be constructed using a composite material with gradient properties. The outer layer of the contact surface is preferably made of a low-hardness elastomer material, whose elastic modulus matches that of human soft tissue, ensuring initial contact comfort. The middle layer can be fitted with a cushioning material with energy-absorbing properties to disperse impact forces during dynamic use. The base layer uses an adhesive layer compatible with the material of the first connecting arm 210, ensuring structural integrity. This layered design allows the first contact portion 212 to adapt to the microscopic changes in the curvature of the head while maintaining macroscopic shape stability.

[0142] In one possible implementation, the second connecting arm 220 may include a second support portion 221 and a second contact portion 222 located inside the second support portion 221. At least a portion of the second cable 120 may be located between the second support portion 221 and the second contact portion 222.

[0143] The second support portion 221 can serve as the outer skeleton of the connecting arm 200, and its cross-sectional shape can be set to U-shaped or C-shaped to form a natural cable accommodating space. The second contact portion 222 can serve as an inner component, and is fixed to the inside of the support portion by means of snap-fit, bonding, or integral molding, forming a continuous cable channel between the two. The second cable 120 can be arranged in this interlayer space, and its direction can be arranged in a straight line along the extension direction of the connecting arm 200.

[0144] The second contact portion 222, serving as a functional interface that directly contacts the user's head, can be constructed using a composite material with gradient properties. The outer layer of the contact surface is preferably made of a low-hardness elastomer material with an elastic modulus matching that of human soft tissue, ensuring initial contact comfort. The middle layer can be fitted with a cushioning material with energy-absorbing properties to disperse impact forces during dynamic use. The base layer uses an adhesive layer compatible with the material of the second connecting arm 220, ensuring structural integrity. This layered design allows the second contact portion 222 to adapt to the microscopic changes in the curvature of the head while maintaining macroscopic shape stability.

[0145] In one possible implementation, the first connecting arm 210 may be provided with a first cable management structure 213, which can fix the first cable 110.

[0146] The first cable management structure 213 can be integrated into the interior or surface of the first connecting arm 210 in various forms. For example, the first cable management structure 213 can be cable fixing points spaced apart along the extension direction of the first connecting arm 210, and each cable fixing point can include a limiting buckle or an elastic clamping device to prevent unintended movement of the cable while maintaining the necessary allowance for movement.

[0147] The arrangement density of the first cable management structure 213 can be optimized according to the rigidity and expected range of motion of the first cable 110. The first cable management structure 213 and the first connecting arm 210 can be manufactured using an integral molding process, or they can be installed as independent components in a preset position by screws or clips.

[0148] In one possible implementation, the second connecting arm 220 may be provided with a second cable management structure 223, which can fix the second cable 120.

[0149] The second cable management structure 223 can be integrated into the interior or surface of the second connecting arm 220 in various forms. For example, the second cable management structure 223 can be cable fixing points spaced apart along the extension direction of the second connecting arm 220. Each cable fixing point can include a limiting buckle or an elastic clamping device to prevent unintended movement of the cable while maintaining the necessary allowance for movement.

[0150] The arrangement density of the second cable management structure 223 can be optimized according to the rigidity and expected range of motion of the second cable 120. The second cable management structure 223 and the second connecting arm 220 can be manufactured using an integral molding process, or they can be installed as independent components in a preset position by screws or clips.

[0151] Precise cable positioning is achieved through the first cable management structure 213 and the second cable management structure 223, which can reduce wear caused by friction and extend the service life of the cable; the orderly cabling method can reduce the risk of electromagnetic interference and improve the signal transmission quality; the modular fixing structure facilitates the installation and maintenance of the cable; it can also keep the appearance of the head-mounted display device clean and avoid the interference to the user's vision caused by exposed cables.

[0152] In one possible implementation, the first cable management structure 213 may be a first receiving groove 214. The first receiving groove 214 is located on the surface of the first support portion 211 facing the second contact portion 222. The first receiving groove 214 may accommodate a portion of the first cable 110.

[0153] The first receiving groove 214 can be arranged along the extension direction of the first support 211, and its cross-sectional profile can be set as an arc-shaped groove adapted to the diameter of the first cable 110 to ensure that the first cable 110 has appropriate room for movement after being inserted.

[0154] The first receiving groove 214 and the first contact part 212 can form a coordinated cable management system. When the first contact part 212 is installed, its inner surface fits tightly with the opening edge of the first receiving groove 214, turning the originally open cable groove into a fully enclosed protective channel, while keeping the contact surface flat and not affecting wearing comfort.

[0155] In one possible implementation, the second cable management structure 223 may be a second receiving groove 224. The second receiving groove 224 is located on the surface of the second support portion 221 facing the first contact portion 212. The second receiving groove 224 may accommodate a portion of the second cable 120.

[0156] The second receiving groove 224 can be arranged along the extension direction of the second support 221, and its cross-sectional profile can be set as an arc-shaped groove adapted to the diameter of the second cable 120 to ensure that the second cable 120 has appropriate room for movement after being inserted.

[0157] The second receiving groove 224 and the second contact part 222 can form a cooperative cable management system. When the second contact part 222 is installed, its inner surface fits tightly with the opening edge of the second receiving groove 224, turning the originally open cable groove into a fully enclosed protective channel, while keeping the contact surface flat and not affecting wearing comfort.

[0158] like Figure 7 , Figure 8 As shown, in one possible implementation, the first connecting arm 210 may be provided with a first limiting member 215. The first limiting member 215 is slidably disposed on the first connecting arm 210. The first limiting member 215 can guide the arrangement of the first cable inside the first connecting arm 210.

[0159] The first limiting member 215 can slide along the extension direction of the first connecting arm 210 to constrain the first cable on the inner surface of the first connecting arm 210 and guide it to the first headband area, ensuring the regularity of the cable routing path.

[0160] The second connecting arm 220 may be provided with a second limiting member 225. The second limiting member 225 is slidably disposed on the second connecting arm 220. The second limiting member 225 can be used to guide the arrangement of the second cable inside the second connecting arm 220.

[0161] The second limiting member 225 can slide along the extension direction of the second connecting arm 220 to constrain the second cable on the inner surface of the second connecting arm 220 and guide it to the second headband area, ensuring the regularity of the cable routing path.

[0162] like Figure 9 As shown, in one possible implementation, the first connecting arm 210 may be provided with a first cable guide 216. The first cable guide 216 may be provided on the upper side, lower side, left side or right side of the first connecting arm 210, and guides the first cable from the front end of the first connecting arm 210 to the rear end of the first connecting arm 210 through an open structure.

[0163] The second connecting arm 220 may be provided with a second cable guide 226. The second cable guide 226 may be located on the upper side, lower side, left side or right side of the second connecting arm 220, and guides the second cable from the front end of the second connecting arm 220 to the rear end of the second connecting arm 220 through an open structure.

[0164] like Figure 10 , Figure 11 As shown, in one possible implementation, the first connecting arm 210 may be provided with a first cable channel 217. The first cable channel 217 extends longitudinally along the first connecting arm 210, passing through from the front end of the first connecting arm 210 to the rear end of the first connecting arm 210, forming a completely closed cable transmission path. The first cable is disposed within the first cable channel 217 and can be adapted to fit the diameter of the first cable channel 217. The sheath of the first cable is removed, leaving only the necessary insulation layer, to ensure that the bare wire bundle can pass through the first cable channel 217.

[0165] The second connecting arm 220 may be provided with a second cable channel 227. The second cable channel 227 extends longitudinally along the second connecting arm 220, passing through from the front end of the second connecting arm 220 to the rear end of the second connecting arm 220, forming a completely closed cable transmission path. The second cable is disposed within the second cable channel 227 and can be adapted to fit the diameter of the second cable channel 227. The sheath of the second cable is removed, leaving only the necessary insulation layer, to ensure that the bare wire bundle can pass through the second cable channel 227. In one possible embodiment, a mask 130 may be provided on the rear light-emitting side of the display device body 100.

[0166] In the overall structure of the head-mounted display device, the display device body 100 is provided with a dedicated optical output interface. The rear light-emitting side of this interface can refer to the optical surface of the display device body 100 facing the user's face, which is used to project the display content into the user's visual range.

[0167] A mask 130 is provided on the rear light-emitting side of the display device body 100, which can optimize the optical transmission path and provide necessary human-machine interface adaptation. The inner surface of the mask 130 can be constructed as a curved surface that conforms to the user's facial contours, ensuring that the display device body 100 and the eyes maintain the optimal relative position.

[0168] In one possible implementation, the face mask 130 can be detachably connected to the display device body 100. A detachable face mask 130 facilitates cleaning and maintenance by the user, and allows for flexible switching between immersive and non-immersive usage modes of the head-mounted display device. Specifically, the detachable connection method can include magnetic, snap-on, or sliding rail types.

[0169] The detachable connection of the face mask 130 enables flexible switching between immersive and non-immersive usage modes for the head-mounted display device. When the face mask 130 is installed, it forms a complete optical closed system with the rear light-emitting side of the display device body 100, providing a fully immersive visual experience. When the face mask 130 is removed, the display device body 100 can be stably maintained in a suspended wearing state in front of the user's face through the triangular support system formed by the first headband assembly 300 and the second headband assembly 400. This suspended wearing state achieves precise spatial positioning through the synergistic effect of the first headband assembly 300 and the second headband assembly 400, while preserving the visual field channel in the edge area of ​​the head-mounted display. This allows for environmental perception while maintaining the stability of the displayed content, enabling the user to observe the surrounding real environment and forming a visual experience that combines the virtual and real worlds.

[0170] The state transition mechanism of the mask 130 provides users with configurable visual mode selection: in scenarios requiring complete immersion, installing the mask 130 can achieve complete optical isolation; in applications requiring environmental awareness, removing the mask 130 can enable mixed reality vision functionality.
