Description

Head-mounted display device and image display system Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a head-mounted display device and an image display system. Background Art

[0002] At present, head-mounted display devices such as FPV flight goggles (First Person View, FPV), virtual reality glasses (Virtual Reality, VR), and augmented reality glasses (Augmented Reality, AR) can enhance people's enjoyment of watching videos and have become increasingly popular technological products in people's lives, studies, and entertainment.

[0003] In the prior art, the glasses of head-mounted display devices are typically mounted on the user's head via a headband, making it easier for the user to watch videos. However, due to factors such as the miniaturization of the glasses, some modules that provide specific functions for the head-mounted display device, such as the battery, are often designed separately from the glasses, leaving the battery exposed outside the glasses. For such head-mounted display devices, the battery is difficult to store with the glasses, making the head-mounted display device inconvenient to carry.

[0081] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the following further describes this application in detail with reference to the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain this application and do not limit the scope of protection of this application.

[0082] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0083] The head-mounted display device provided in the embodiments of the present disclosure may be VR glasses, AR glasses, MR glasses, or FPV flight goggles, etc. The head-mounted display device can send optical signals to the wearer's eyes through a head-mounted display to achieve different perception effects such as virtual reality (VR), augmented reality (AR), mixed reality (MR), and first-person view (FPV).

[0084] As shown in Figures 1 and 2, in some embodiments of the present disclosure, the head-mounted display device 100 includes a pair of glasses 110, a headband 120, and a load 130. The load 130 is connected to the pair of glasses 110 through the headband 120. The head-mounted display device 100 includes a use state and a storage state. When in the use state, the pair of glasses 110 and the load 130 form a wearing space through the headband 120 and are thus worn by the user. When the head-mounted display device 100 is in the storage state, the load 130 can be fixed to the pair of glasses 110. The distance between the pair of glasses 110 and the load 130 is reduced and is smaller than the distance between the two in the storage state, thereby making the overall volume of the head-mounted display device 100 smaller, which is conducive to storage and convenient to carry.

[0085] Figure 1 shows a schematic diagram of the structure of a head-mounted display device in use, as shown in one embodiment. When the head-mounted display device 100 is in use, the load 130 is separated from the eyeglass body 110, increasing the distance between the load 130 and the eyeglass body 110. The headband 120 is connected to the load 130 and the eyeglass body 110, respectively, to form a wearing space that fits over the user's head, making it easier for the user to wear the glasses.

[0086] Figures 2 and 3 illustrate a schematic diagram of the structure of a head-mounted display device in a stowed state, as shown in one embodiment. When the head-mounted display device 100 is in the stowed state, the load 130 can be secured to the eyeglass body 110. This ensures a more stable positional relationship between the load 130 and the eyeglass body 110 than when in use, reducing the overall size of the head-mounted display device. This facilitates storage and portability.

[0087] It should be noted that there can be many specific implementation methods for "when the head-mounted display device 100 is in the storage state, the load 130 can be fixed to the eyeglass body 110", for example, the load 130 and the eyeglass body 110 are fixed together through the action of the headband 120, for example, the two are fixed together through the interaction between the load 130 and the eyeglass body 110.

[0088] In some embodiments, the number of headbands 120 can be one, two, or three or more, as long as the load and the eyeglass body are connected together to form a wearing space.

[0089] It should be noted that the headband 120 can be implemented in various forms, such as cloth straps, silicone straps, plastic straps, chain straps, etc. These headbands 120 usually have a certain degree of flexibility and elasticity. On the one hand, it is conducive to flexible setting of the headband according to actual conditions, such as the shape of the headband, etc. On the other hand, it can also provide users with better wearing comfort.

[0090] As shown in FIG1 , in some embodiments, the load 130 is positioned opposite the eyeglass body 110. When in use, the eyeglass body 110 is positioned on the user's face, and the load 130 is positioned behind the user's head, preventing the load 130 from exerting pressure on the user's face or ears, thereby improving wearing comfort.

[0091] In some embodiments, the load includes at least one of a battery module, a headband length adjustment module, a communication module, a storage module, and a data processing module. Separating these load modules, which provide specific functions for the head-mounted display device, from the eyewear body reduces the number of modules installed within the eyewear body, facilitating miniaturization and lightweighting of the eyewear body, thereby improving the wearing comfort and aesthetics of the head-mounted display device.

[0092] As shown in Figure 1, in some embodiments, the load 130 is a battery module 135, which can power the eyeglasses. It will be readily understood that the battery module 135 can serve as a working power source, providing power to the eyeglasses 110 during operation. Alternatively, the battery module 135 can serve as a backup power source, providing power when the working power source within the eyeglasses 110 is insufficient. Positioning the battery module 135 outside the eyeglasses 110 also facilitates a larger battery module and increased battery capacity.

[0093] As shown in Figure 1, in some embodiments, the load 130 can also be a headband length adjustment module 134 in addition to the battery module 135. The headband length adjustment module 134 is connected to the headband 120. The length of the headband 120 between the load 130 and the eyeglass body 110 is adjusted through the headband length adjustment module 134 to adapt to different head sizes and improve user wearing comfort.

[0094] It should be noted that there are many specific implementation methods for the headband length adjustment module 134, including a gear rack telescopic adjustment component, a ratchet adjustment mechanism, a headband tightening mechanism, and any other technical implementation that can meet the requirements, which will not be repeated here.

[0095] In some embodiments, the load may be a communication module, which may communicate with the glasses body, such as when a user sends a control command to the glasses body through the load, and the communication module transmits the control command to the glasses body. Of course, the communication module may also communicate with other devices other than the head-mounted display device, such as for receiving control instructions sent by the user from other devices to the head-mounted display device. Of course, the communication module may also be an image transmission module, which transmits image transmission information such as audio and video data between the head-mounted display device and other devices. Using the communication module as a load, on the one hand, can avoid setting a control mechanism on the glasses body in order to control the glasses body, reduce the complexity of the glasses body structure, and contribute to the lightweight and compactness of the glasses body. On the other hand, the communication module is separated from the glasses body to avoid possible interference with the communication module caused by components in the glasses body, reduce communication interference such as electromagnetic interference between the glasses body and the communication module, and facilitate the stable transmission of communication signals, resulting in a better user experience.

[0096] In some embodiments, the load can be a storage module used to store audio and video data that needs to be played by the glasses body. Setting the storage module to be separated from the glasses body is conducive to making the storage module larger so as to facilitate the storage of more audio and video data, thereby avoiding an increase in the weight of the glasses body due to an overly large storage module, and avoiding damage to the storage module due to excessive heat of the glasses body.

[0097] In some embodiments, the load may be a data processing module that processes audio and video data to suit the glasses for playback, such as adjusting image clarity, video frame rate, and other parameters. Separating the data processing module from the glasses prevents it from being affected by excessive heat generated by the glasses during playback.

[0098] It is easy to understand that the load 130 can be composed of two or more different modules, which can be fixed together in different ways such as stacking or juxtaposition. As shown in Figure 1, the load 130 includes a battery module 135 and a headband length adjustment module 134. In this way, different functions can be achieved through a single load 130, which helps to reduce the overall volume of the load 130.

[0099] As shown in FIG1 , in some embodiments, the headband 120 is provided with a transmission cable 122, which connects the battery module 135 to the eyeglass body 110 via the transmission cable 122. The transmission cable 122 is used to transmit power and / or communicate between the battery module and the eyeglass body. In this way, the protective effect of the headband 120 reduces the possibility of damage to the transmission cable 122 during use or storage of the head-mounted display device, and helps improve the aesthetics of the head-mounted display device.

[0100] It should be noted that the specific implementation of the headband 120 being provided with the transmission line 122 includes at least a portion of the external transmission line 122 and / or at least a portion of the internal transmission line 122 .

[0101] Based on the above embodiments, as shown in FIG1 , in some embodiments, a headband 120 is provided with an expandable portion 121, into which a portion of a transmission cable 122 is embedded. The length of the transmission cable embedded in the expandable portion 121 is adjustable. In this way, when the headband 120 expands and contracts to change length, the provision of the transmission cable 122 does not affect the change in length of the headband 120.

[0102] It should be noted that there are many specific implementation methods for the telescopic portion 121, including elastic telescopic, mechanical telescopic, etc., and the transmission line in the telescopic portion 121 can be set to be spring-shaped, etc.

[0103] In addition, "spring-shaped" should be understood in a broad sense, including three-dimensional spring-shaped and two-dimensional spring-shaped forms, so that the transmission line can adapt to the length change of the telescopic part.

[0104] Optionally, part of the transmission line is spring-shaped and includes at least two arc-shaped segments connected in sequence along the telescopic direction of the telescopic portion.

[0105] In some embodiments, the telescopic portion 121 includes an elastic structure or a coaxial sleeve structure to enable the length of the headband 120 to be variable.

[0106] Based on any of the above embodiments, referring back to Figures 1 and 2, in some embodiments, the eyeglass body 110 includes a fitting portion 111 for fitting to the user's face, and the fitting portion 111 is provided with a storage space 112. If the fitting portion 111 is a face mask, the face mask allows the head-mounted display device to fit more closely to the user's face, reducing light entry and improving wearing comfort. When the head-mounted display device 100 is in the stowed state, at least a portion of the load 130 can be located within the storage space 112. In this way, the fitting portion 111 can better fit the user's face, improving both wearing comfort and the user's viewing experience. Furthermore, when stowed, at least a portion of the load 130 can be located within the storage space 112, ensuring a tighter fit between the load 130 and the eyeglass body 110, thereby making the head-mounted display device 100 smaller in the stowed state and more convenient to carry.

[0107] As shown in Figures 1 and 2, the load 130 includes a first side 131 and a second side 132. The first side 131 is the side of the load 130 facing the user's head when the head-mounted display device 100 is worn, and the second side 132 is the side of the load 130 facing away from the user's head when the head-mounted display device 100 is worn.

[0108] In some embodiments, the first side 131 includes a concave surface because the first side 131 has a certain curvature, thereby facilitating a fit with the user's head. In addition, in some cases, the load 130 is generally curved, such as a "C" shape, to fit the user's head. Therefore, when stored, the second side 132 can be directed toward the eyeglass body 110, and the first side 131 can be placed against the eyeglass body, so that the load 130 and the eyeglass body 110 fit more tightly, thereby making the head-mounted display device 100 smaller in the stored state and more convenient to carry.

[0109] It is understandable that the first side 131 may be provided with a headrest 133 that fits the user's head, so as to facilitate fit with the user's head and improve the wearing comfort of the head-mounted display device 100.

[0110] It should be noted that the headrest 133 can be implemented in various forms, including but not limited to at least one of a foam pad, a foam pad, a plastic pad, etc.

[0111] Furthermore, in some embodiments, the second side is not a flat surface. For example, if the load 130 is generally curved, such as in a "C" shape, the second side may be a curved surface. Alternatively, the second side may be provided with an operating member protruding from its surface, resulting in a convex surface on the second side. Therefore, when stored, the second side 132 can be oriented toward the eyeglass body 110, and the space within the eyeglass body 110, such as the storage space 112 of the fitting portion 111, can be utilized to accommodate the second side within the storage space 112. This fully utilizes the shape of the load 130 and reduces the storage volume.

[0112] In some embodiments, in order to facilitate the user to operate the head-mounted display device, operating elements can be set on the load. These operating elements can be used to control the headband, the load or the glasses body. In addition, in order to facilitate the user to operate these operating elements when wearing, operating elements are set on the second side, and these operating elements can protrude from the surface of the second side. Therefore, when storing, the second side 132 can be turned toward the glasses body 110, and the protective effect of the glasses body 110 can be used to avoid accidental touching of these operating elements by the outside world during storage, thereby avoiding damage to the head-mounted display device. If the operating element is a power button, it can prevent the power button from being accidentally touched, causing the head-mounted display device to always be turned on, thereby consuming the battery module and reducing its life.

[0113] As shown in Figures 1 to 3, in some embodiments, a headband length adjustment module 134 is provided on the second side 132, and the length adjustment module is in a convex shape. As shown in Figures 4 and 6, in some embodiments, a limiting mechanism 140 such as a locking assembly 141 is provided on the load, and the locking assembly 141 at least partially protrudes from the surface of the second side. Therefore, when stored, the second side 132 can be oriented toward the eyeglass body 110 to fit the eyeglass body, that is, the protruding portion of the second side 132 can be at least partially accommodated in the space formed by the eyeglass body 110, so that the load 130 and the eyeglass body 110 fit more tightly, thereby making the head-mounted display device 100 smaller in size in the stored state and more convenient to carry.

[0114] Based on any of the above embodiments, as shown in FIG4 and FIG5 , in some embodiments, when the head-mounted display device 100 is in the stored state, the headband 120 is wrapped around at least one of the load 130 and the eyeglass body 110. This facilitates the use of the load 130 and / or the eyeglass body 110 to wrap the headband 120 for storage. By storing the headband 120 together with the load 130 and / or the eyeglass body 110, the structure of the head-mounted display device 100 in the stored state becomes more compact and convenient to carry.

[0115] The following describes an example of a specific implementation method in which the load can be fixed to the glasses body when the head-mounted display device is in the storage state.

[0116] In some embodiments, the load 130 is detachably connected to the head-mounted display device 100. The load 130 can be removed from the head-mounted display device 100 and then fixed to the eyeglass body 110. In this way, when the head-mounted display device 100 needs to be stored, the load 130 is separated from the head-mounted display device 100, making it easier to fix the load 130 to the eyeglass body 110 and achieve storage of the head-mounted display device 100. In other words, the load 130 and the eyeglass body 110 switch from a state of being connected via the headband 120 to a state of being stored.

[0117] It should be noted that there are many specific implementations of “the load 130 is detachably connected to the head-mounted display device 100 ”.

[0118] In some embodiments, the load 130 is detachably connected to the headband 120 . After the load 130 is separated from the headband 120 , the load 130 can be fixed to the eyeglass body 110 .

[0119] In some embodiments, the load 130 and the headband 120 are detachably connected to the eyeglass body 110 as a whole, and the load 130 and the headband 120 are separated from the eyeglass body 110 as a whole. The separated load 130 and the headband 120 are used to be fixed to the eyeglass body 110 as a whole.

[0120] In some embodiments, the load 130 and the headband 120, as well as the headband 120 and the eyeglass body 110, can be detachably connected, that is, the three become independent entities after separation. The separated load 130 can be fixed to the eyeglass body 110, and the headband 120 can be stored separately. Of course, the headband 120 can also be fixed together with the load 130 and the eyeglass body 110, such as by bundling the load 130 and the eyeglass body 110 together through the winding action of the headband.

[0121] In some embodiments, the headband 120 itself is detachably connected, for example, the headband 120 includes at least two detachably connected straps, and the load 130 is connected to the detachable straps. After the connection state of the detachably connected straps is disconnected, the load 130 and the detachable straps are separated from the eyeglass body 110 as a whole, and the separated part of the whole is used to be fixed to the eyeglass body 110.

[0122] In the above embodiment, since the load 130 can be detached from the head mounted display device 100 and then fixed to the glasses body 110 , the storage method is flexible and can be selected according to actual needs.

[0123] It should be noted that the above-mentioned detachable connection includes a purely mechanical detachable connection and a detachable connection with an electrical connector.

[0124] For example, the headband 120 is provided with a transmission line 122 to realize electrical connection between the load 130 and the eyeglass body 110. The transmission line 122 can be detachably electrically connected to the load 130 and / or the eyeglass body 110 through an electrical connector, and at the same time, the connection between the headband 120 and the load 130 and / or the eyeglass body 110 is realized by using detachable structures such as snaps, magnets, screws, and adhesives.

[0125] In some embodiments, based on any of the above embodiments, the head-mounted display device is provided with a limiting mechanism, which is located on at least one of the eyeglass body and the load. When the head-mounted display device is in the stowed state, the limiting mechanism secures the load to the eyeglass body. When the limiting mechanism is released, the eyeglass body and the load can be separated for wear by the user.

[0126] It should be noted that the specific implementation of the limiting mechanism can be various, including but not limited to locking, snapping, sleeve connection, magnetic attraction, bonding, and other mechanisms, as long as they can produce a limiting effect to fix the load 130 to the eyeglass body 110. For example, the eyeglass body 110 can be sleeved onto the load 130 to achieve fixation between the two, or the eyeglass body 110 and the load 130 can be snapped and locked together.

[0127] In conjunction with the above embodiments, as shown in Figures 4 to 6, in some embodiments, the limiting mechanism 140 includes a locking assembly, which includes a locking member 141 and a locking member 142 that locks with the locking member 141. One of the locking member 141 and the locking member 142 is disposed on the eyeglass body 110, and the other is disposed on the load 130. In this manner, when the head-mounted display device 100 is in the stowed state, the locking member 142 and the locking member 141 lock together to secure the load 130 to the eyeglass body 110. When the head-mounted display device 100 is to be worn, the locking member 142 and the locking member 141 are unlocked and engaged, thereby separating the load 130 from the eyeglass body 110 and facilitating engagement with the headband 120 to form a wearing space.

[0128] In some embodiments, the load 130 is provided with a locking member 142 having a lock hole. Correspondingly, the eyeglass body 110 is provided with a locking member 141, which is a lock tongue. Thus, the lock tongue and the lock hole cooperate to lock the load 130 to the eyeglass body 110, and the lock tongue and the lock hole separate to separate the load 130 from the eyeglass body 110.

[0129] In some embodiments, one of the locking member 141 and the locking member 142 is a magnetic member (not shown), and the other is a magnetic conductive member (not shown) that magnetically cooperates with the magnetic member. In this way, the load 130 is locked to the eyeglass body 110 by magnetically fixing the magnetic member and the magnetic conductive member, and the load 130 is separated from the eyeglass body 110 by separating the magnetic member and the magnetic conductive member, thereby facilitating assembly and disassembly.

[0130] In addition, the magnetic element and the magnetic conductive element are easy to be built-in and will not affect the appearance of the load 130 and the eyeglass body 110.

[0131] In some embodiments, the locking member 141 is a clamping portion (not shown), and the locking member 142 is a buckle portion (not shown). Thus, the load 130 is locked to the eyeglass body 110 by the engagement of the clamping portion and the buckle portion, and the load 130 is separated from the eyeglass body 110 by the separation of the clamping portion and the buckle portion.

[0132] In some embodiments, the locking member 141 is a male Velcro (not shown), and the locking member 142 is a female Velcro (not shown). Thus, the male Velcro and the female Velcro are bonded together to lock the load 130 to the eyeglass body 110, and the male Velcro and the female Velcro are separated to separate the load 130 from the eyeglass body 110.

[0133] Based on any of the above embodiments of the limiting mechanism 140, in some embodiments, when the head-mounted display device 100 is in the storage state, the limiting mechanism 140 is used to lock at least a portion of the load 130 within the storage space 112. In this way, the limiting mechanism 140 facilitates the positional fixation of the load 130 on the eyeglass body 110, and at least a portion of the load 130 is confined within the storage space 112. After the limiting mechanism 140 is unlocked, the eyeglass body 110 and the load 130 can be separated for wear by the user.

[0134] Based on any of the above embodiments of the locking assembly, in some embodiments, one of the locking member 141 and the locking member 142 is disposed on the fitting portion 111, and the other is disposed on the payload 130. In this way, a portion of the payload 130 can be better stored and fixed in the storage space 112.

[0135] In combination with any of the above embodiments, in some embodiments, when the head-mounted display device 100 is in the storage state, the load 130 is fixed to the eyeglass body 110 through the headband 120 .

[0136] As shown in Figures 7 to 13 , in some embodiments, after the headband 120 is disconnected from the load 130 and the eyeglass body 110, the headband 120 wraps the load 130 and the eyeglass body 110 together to secure them. By directly securing the load 130 to the eyeglass body 110 via the headband 120, the number of retaining mechanisms required for securing the load 130 can be reduced, facilitating miniaturization of the load 130 and the eyeglass body 110.

[0137] Of course, in some embodiments, the headband 120 can be combined with the limiting mechanism 140 to secure the load 130 to the eyeglass body 110. As shown in FIG5 , in some embodiments, when the head-mounted display device 100 is in the stowed state, the load 130 is secured to the eyeglass body 110 by the limiting mechanism 140, and the headband 120 also secures the load 130 to the eyeglass body 110.

[0138] Referring back to Figures 1 to 3, in some embodiments, the headband 120 includes a first band 123 and a second band 124, wherein both ends of the first band 123 are respectively connected to the load 130 and the eyeglass body 110, and both ends of the second band 124 are respectively connected to the load 130 and the eyeglass body 110.

[0139] It should be noted that the present invention uses the load 130 and the eyeglass body 110 as the boundary, and defines the headband 120 located between the two as the first band 123 and the second band 124 respectively, regardless of whether the first band 123 and the second band 124 are two independent bands or a whole band.

[0140] When the head-mounted display device 100 is in use, the ends of the first strap 123 are connected to the load 130 and the eyeglass body 110, respectively. The ends of the second strap 124 are connected to the load 130 and the eyeglass body 110, respectively, to form a wearing space for the user to wear. When the head-mounted display device 100 is in the stored state, at least a portion of the second strap 124 is wrapped around at least one of the load 130 and the eyeglass body 110 to secure the load 130 to the eyeglass body 110.

[0141] Optionally, in some embodiments, the second strap 124 is detachably connected to at least one of the load 130 and the eyeglass body 110. Thus, when the head-mounted display device 100 needs to be stored, the second strap 124 is separated from the load 130, the eyeglass body 110, or both. The load 130 and the eyeglass body 110 are then adjusted to a storage position (e.g., so that they fit snugly together), and the second strap 124 is then used to secure the load 130 and the eyeglass body 110 together, thereby achieving storage of the head-mounted display device 100.

[0142] In the stowed state where the load 130 and the eyeglass body 110 are fixed together by the second strap, the first strap 123 can be in the stowed state in different ways.

[0143] As shown in FIG7 , in some embodiments, when the head-mounted display device 100 is in the stowed state, the first strap 123 is wrapped around the surface of the load 130. Thus, when the head-mounted display device 100 needs to be stowed, the second strap is detached, and the first strap 123 is wrapped around the surface of the load 130 to stow the first strap 123. The first strap 123 is then secured to the eyeglass body 110 along with the load 130, completing the stowage of the head-mounted display device 100.

[0144] As shown in FIG8 , in some embodiments, the first strap 123 is folded and stored within the load 130 or the eyeglass body 110. Thus, when the head-mounted display device 100 needs to be stored, the second strap 124 is separated, and the first strap 123 is folded and stored within the load 130 or the eyeglass body 110 to achieve storage of the first strap 123. The load 130 is then secured to the eyeglass body 110 via the second strap 124, completing storage of the head-mounted display device 100.

[0145] It should be noted that the first belt 123 is folded and stored in the load, including the first belt 123 is folded and stored in the surface of the load, or at least part of the first belt 123 is folded and stored in the storage space formed by the load surface, such as the recess of the load.

[0146] It should be noted that the first band 123 is folded and stored in the glasses body, including the first band 123 being folded and stored in the surface of the glasses body, or at least part of the first band 123 being folded and stored in the storage space formed on the surface of the glasses body, such as the recess of the glasses body.

[0147] Alternatively, in conjunction with the fitting portion 111 described in the aforementioned embodiment, the first strap 123 is folded and stored within the storage space 112 of the eyeglass body 110. The payload 130 is then placed over the storage space 112 to store the first strap 123. The payload 130 is then secured to the eyeglass body 110 via the second strap 124, allowing the head-mounted display device 100 to be stored. During this process, the first strap 123 is folded and stored within the storage space 112 of the eyeglass body 110. This allows the head strap 120 to be stored in the eyeglass body 110, enhancing the aesthetic appearance of the stored head-mounted display device 100.

[0148] Based on any of the above embodiments of the headband 120, as shown in FIG9 , in some embodiments, the first strap 123 is wound and stored within at least one of the load 130 and the eyeglass body 110. This allows the second strap 124 to be detached when the head-mounted display device 100 needs to be stored. The first strap 123 is wound and stored within at least one of the load 130 and the eyeglass body 110, thereby storing the first strap 123. The load 130 is then secured to the eyeglass body 110 via the second strap 124, allowing the head-mounted display device 100 to be stored.

[0149] It should be noted that "the winding and storage of the first strap 123" can be performed by the winding mechanism 160, or the first strap 123 can be wound up into a whole and then placed inside the load 130, the eyeglass body 110, or both. Any winding and storage is sufficient, and no further limitations are imposed here.

[0150] Based on any of the above embodiments, in some embodiments, the second strap 124 secures the load to the eyeglass body via a first mating portion, and the first mating portion is provided on at least one of the load, the eyeglass body, the first strap 123, and the second strap 124. Thus, by providing the first mating portion on at least one of the eyeglass body, the first strap 123, and the second strap 124, and then utilizing the second strap 124 to engage with the first mating portion, the load is secured to the eyeglass body, which is easily achieved.

[0151] As shown in Figures 7 to 9, the first matching portion 101 is disposed on the load 130. The load 130 is tightly attached to the eyeglass body 110, and the second strap 124 is connected to the first matching portion 101 to bind the load 130 and the eyeglass body 110 together.

[0152] As shown in FIG10 , the first fitting portion 101 is disposed on the eyeglass body 110 . After the load 130 is tightly attached to the eyeglass body 110 , the second strap 124 is connected to the first fitting portion 101 to bind the load 130 and the eyeglass body 110 together.

[0153] As shown in Figures 11 and 12, the first mating portion 101 is provided with a second strap 124. Thus, after the load 130 is tightly attached to the eyeglass body 110, the second strap 124 is connected through the first mating portion to form a binding loop to bind the load 130 and the eyeglass body 110 together.

[0154] As shown in Figures 2, 3 and 13, the first matching portion 101 is provided with a first strap 123. Thus, after the load 130 is tightly attached to the eyeglass body 110, the second strap 124 is connected to the first strap 123 through the first matching portion 101, thereby binding the load 130 and the eyeglass body 110 together.

[0155] As shown in Figures 1 to 3 , when the load 130 and the eyeglass body 110 are switched from the in-use state to the stored state, the second strap 124 separates from the eyeglass body 110, and the second side 132 of the load 130 flips over, driving the first strap 123 to surround the first side 131. After the second side 132 of the load 130 is in close contact with the contact portion 111 of the eyeglass body 110, the first mating portion 101 on the first strap 123 is positioned outside the first side 131, and the second strap 124 is connected to the first mating portion 101, thereby connecting the second strap 124 to the first strap 123 and binding the load 130 and the eyeglass body 110 together.

[0156] Based on any of the above embodiments, the second strap 124 includes a first connecting portion (not shown) that is detachably connected to one of the load 130 and the eyeglass body 110. When the head-mounted display device 100 is in the stowed state, the connection between the first connecting portion and the load 130 or the eyeglass body 110 is disconnected, allowing the first connecting portion to engage with the first mating portion 101 to secure the load 130 to the eyeglass body 110. Thus, when the head-mounted display device 100 needs to be stowed, the first connecting portion can be detached from one of the load 130 and the eyeglass body 110, placing the second strap 124 in a detached state. After the load 130 and the eyeglass body 110 are adjusted to the stowed position (e.g., so that they fit snugly), the first connecting portion can engage with the first mating portion 101, allowing the second strap 124 to secure the load 130 and the eyeglass body 110 together, thereby achieving stowage of the head-mounted display device 100.

[0157] Based on any of the above-mentioned embodiments of the first connecting portion 102, as shown in FIG12 , in some embodiments, the first mating portion 101 is disposed at one end of the second strap 124, and the first mating portion 101 is detachably connected to the other of the load 130 and the eyeglass body 110. In the stowed state, the first mating portion 101 is disconnected from the other of the load 130 and the eyeglass body 110, allowing the first connecting portion 102 to mate with the first mating portion 101. Thus, the first connecting portion 102 and the first mating portion 101 are separately disposed on the second strap 124. In use, one end of the second strap 124 is connected to the load 130, and the other end is connected to the eyeglass body 110. In the stowed state, one end of the second strap 124 is connected to the other end of the second strap 124, securing the load 130 and the eyeglass body 110 together.

[0158] As shown in FIG14 , in one exemplary embodiment, the head-mounted display device 100 further includes a third strap 150. One end of the third strap 150 is fixedly connected to one of the load 130 and the eyeglass body 110. One end of the second strap 124 is fixedly connected to the other of the load 130 and the eyeglass body 110. The other end of the third strap 150 is detachably connected to the other end of the second strap 124 via the first connecting portion 102. Thus, when the head-mounted display device 100 needs to be stored, the first connecting portion 102 can be detached from one of the load 130 and the eyeglass body 110, leaving the second strap 124 in a detached state. After the load 130 and the eyeglass body 110 are adjusted to a stored position (e.g., so that they fit snugly), the first connecting portion 102 can engage with the first engaging portion 101, allowing the second strap 124 to secure the load 130 and the eyeglass body 110 together, thereby achieving storage of the head-mounted display device 100. When the head-mounted display device 100 is in use, by setting the third strap 150, while satisfying the binding and fixing effect of the second strap 124, it is convenient to flexibly adjust the length of the third strap 150 or the matching position of the third strap 150 and the second strap 124 to adapt to the wearing space required by different sizes of loads 130 and different sizes of glasses bodies 110.

[0159] In addition, in combination with the aforementioned embodiment of the headband length adjustment module 134 , the third strap 150 is connected to the headband length adjustment module 134 , and the wearing length of the third strap 150 and the second strap 124 can be easily adjusted by adjusting the extension length of the third strap 150 .

[0160] Of course, in other embodiments, when the third strap 150 is not provided, the second strap 124 and the headband length adjustment module 134 can be detachably connected. In this manner, after the second strap 124 is connected to the headband length adjustment module 134, the wearing length can be adjusted by adjusting the extension length of the second strap 124. Furthermore, after the second strap 124 is detached from the headband length adjustment module 134, the second strap 124 can be used to directly or indirectly secure the payload 130 and the eyeglass body 110.

[0161] Furthermore, as shown in Figures 14 and 15 , in one exemplary embodiment, the first mating portion 101 is provided on the first strap 123, and the third strap 150 also has a first mating portion 101. Thus, when the head-mounted display device 100 is in use, the first mating portion 101 of the third strap 150 is connected to the first connecting portion 102, thereby connecting the second strap 124 to the third strap 150. When the head-mounted display device 100 needs to be stored, the first mating portion 101 of the third strap 150 is separated from the first connecting portion 102, separating the second strap 124 from the third strap 150. After the load 130 is firmly attached to the eyeglass body 110, the second strap 124 is connected to the first mating portion 101 of the first strap 123 via the first connecting portion 102. This facilitates the mating of the second strap 124 with the first strap 123 to secure the load 130 to the eyeglass body 110, thus enabling storage of the head-mounted display device 100.

[0162] Based on any of the above embodiments, as shown in Figures 16a and 16b, the first connecting portion 102 and the load 130 are detachably connected. When the head-mounted display device 100 is in the stowed state, the second strap 124 surrounds at least a portion of the load 130. In this way, when the head-mounted display device 100 needs to be stowed, the first connecting portion 102 and the load 130 are detachably separated, so that the second strap 124 is in a detached state. Then, by adjusting the load 130 and the eyeglass body 110 to the stowed position (for example, so that the two fit tightly together), after the second strap 124 surrounds at least a portion of the load 130, it is convenient to use the second strap 124 to secure the load 130 and the eyeglass body 110 together, thereby achieving the stowage of the head-mounted display device 100.

[0163] Optionally, as shown in FIG. 17 a and FIG. 17 b , after the second belt 124 is wrapped around the load 130 , it is engaged with the first engaging portion 101 provided on the eyeglass body 110 to fix the load 130 and the eyeglass body 110 together.

[0164] Based on any of the above embodiments, as shown in Figures 17a and 17b, in some embodiments, the first connecting portion 102 is detachably connected to the eyeglass body 110. When the head-mounted display device 100 is in the storage state, the second strap 124 surrounds at least a portion of the eyeglass body 110. In this way, when the head-mounted display device 100 needs to be stored, the first connecting portion 102 and the eyeglass body 110 are detachably separated, so that the second strap 124 is in a detached state. Then, by adjusting the load 130 and the eyeglass body 110 to the storage position (for example, so that the two are tightly fitted), after the second strap 124 surrounds at least a portion of the eyeglass body 110, the load 130 and the eyeglass body 110 can be conveniently secured together using the second strap 124, thereby achieving storage of the head-mounted display device 100.

[0165] Optionally, after the second strap 124 is wrapped around the eyeglass body 110 , it is engaged with the first engaging portion 101 to fix the load 130 and the eyeglass body 110 together.

[0166] It should be noted that the first strap 123 can be stored by at least one of wrapping, folding, and rolling. The second strap 124 can be wrapped clockwise or counterclockwise to secure the load 130 to the eyeglass body 110. During this process, the second strap 124 is also stored while enclosing the load 130, the eyeglass body 110, or both.

[0167] Based on any of the above embodiments, in some embodiments, the first connecting portion and the first matching portion are snap-fitted, so that the snap-fitting can easily realize the detachable connection between the first connecting portion and the first matching portion, and the implementation cost is low.

[0168] Alternatively, as shown in Figures 2 and 3 and Figures 14 and 15 , in some embodiments, one of the first connecting portion 102 and the first mating portion 101 is a hook, and the other is a buckle that snaps into engagement with the hook. In this manner, the connection between the hook and the buckle ensures a secure connection between the first connecting portion 102 and the first mating portion 101. The first connecting portion 102 can be separated from the second mating portion by simply pulling the hook from the buckle, making the operation convenient and simple.

[0169] Furthermore, in one exemplary embodiment, the buckle and the first strap 123 are formed by a flexible strap. In this way, the buckle is integrated into the first strap 123 to facilitate forming the first mating portion 101 on the first strap 123, so as to achieve the connection between the second strap 124 and the first strap 123 to secure the payload 130 and the eyeglass body 110 together.

[0170] Based on any of the above embodiments of the buckle, in some embodiments, the buckle and the second strap are formed by a flexible strap, and the other end of the second strap is provided with a hook. Thus, one end of the second strap is connected to the hook on one of the load and the eyeglass body via the buckle, while the hook on the other end of the second strap is connected to the buckle on the other of the load and the eyeglass body, thereby forming a strap between the load and the eyeglass body. The buckle can be separated from the hook on one of the load and the eyeglass body, and the hook on the other end of the second strap can be separated from the buckle on the other of the load and the eyeglass body, and then connected to the hook via the buckle on the second strap to form a lashing loop, thereby securing the load and the eyeglass body together.

[0171] In some embodiments, the first connecting portion and the first detachable mating portion are bonded together, so that the detachable connection between the first connecting portion and the first mating portion can be achieved by detachable bonding technology.

[0172] For example, one of the first connecting portion 102 and the first mating portion 101 is a male Velcro strip, and the other is a female Velcro strip. The adhesive engagement of the male and female Velcro strips connects the second strap 124 to the load 130 and the eyeglass body 110, facilitating the formation of a connecting strap. In some embodiments, the first connecting portion 102 and the first mating portion 101 mate magnetically. This magnetic engagement allows for a detachable connection between the first connecting portion 102 and the first mating portion 101, facilitating assembly and disassembly.

[0173] Based on any of the above-mentioned embodiments of the second strap 124, referring back to FIG. 1 , in some embodiments, the first strap 123 is connected to the load 130 and the eyeglass body 110, respectively. The first strap 123 is provided with a transmission line 122, and the load 130 is electrically connected to the eyeglass body 110 via the transmission line 122. Thus, by providing the transmission line 122 on the first strap 123 and connecting the first strap 123 to the load 130 and the eyeglass body 110, respectively, the load 130 is electrically connected to the eyeglass body 110 via the transmission line 122, thereby reducing the wearing operation of the head-mounted display device 100 and making it easier for the user to wear and use the head-mounted display device 100.

[0174] As can be understood, the first strap 123 is securely connected to the load 130 and the eyeglass body 110, ensuring a reliable electrical connection between the load 130 and the eyeglass body 110 via the transmission line 122. During use, the user does not need to reinstall the first strap 123. To store the load 130 and the eyeglass body 110, the user simply detaches the second strap 124 from the load 130 and the eyeglass body 110, and then secures the load 130 and the eyeglass body 110 together using the second strap 124. This is a simple operation.

[0175] In addition to any of the above embodiments, as shown in FIG18a and FIG18b , in some embodiments, the head-mounted display device 100 further includes a reeling mechanism 160 disposed on at least one of the load 130 and the eyeglass body 110. Under the action of the reeling mechanism 160, the length of the headband 120 located between the load 130 and the eyeglass body 110 is reduced, thereby bringing the load 130 closer to the eyeglass body 110. When the head-mounted display device 100 is in the stowed state, the reeling mechanism 160 can continuously generate a reeling force to secure the load 130 to the eyeglass body 110. Thus, when the head-mounted display device 100 needs to be stowed, the reeling mechanism 160 reels the headband 120, reducing the length of the headband 120 and bringing the load 130 closer to the eyeglass body 110. Furthermore, the reeling mechanism 160 can continuously generate a reeling force to secure the load 130 to the eyeglass body 110, thereby achieving stowage of the head-mounted display device 100. The headband 120 is wound and stored inside at least one of the load 130 and the eyeglass body 110 , so as to facilitate storage of the headband 120 .

[0176] In addition, the headband 120 is stored inside at least one of the load 130 and the glasses body 110, so that the headband 120 is hidden. The head-mounted display device 100 is more beautiful and technological in the stored state.

[0177] It should be noted that there are many specific implementation methods for the "winding mechanism 160", as long as it can wind up and store the headband 120, and no further restrictions are made here.

[0178] As shown in Figures 18a and 18b, in some embodiments, the winding mechanism 160 includes a coil spring 161, and the winding mechanism 160 elastically winds the headband 120 via the coil spring 161. Thus, utilizing the coil spring 161 facilitates elastic winding of the headband 120 and easily increases the winding force to secure the load 130 to the eyeglass body 110.

[0179] Based on the above-mentioned embodiment of the reeling mechanism 160, as shown in FIG18a and FIG18b, in some embodiments, the reeling mechanism 160 includes a motor 162, and the reeling mechanism 160 electrically reels the headband 120 via the motor 162. In this way, the motor 162 is used to electrically rewind the headband 120, thereby facilitating automatic rewinding of the headband 120 and improving the degree of automation of rewinding.

[0180] It should be noted that although Figures 18a and 18b simultaneously show a winding mechanism with a coil spring 161 and a winding mechanism with a motor 162, it is easy to understand that in some embodiments, the winding mechanism 160 is a winding mechanism with a coil spring 161, and in other embodiments, the winding mechanism 160 is a winding mechanism with a motor 162.

[0181] Based on the above-mentioned embodiment of the reeling mechanism 160, as shown in Figures 18a and 18b, in some embodiments, the reeling mechanism 160 further includes a locking assembly 170 for locking the headband 120 to the load 130 or the eyeglass body 110. Thus, by using the locking assembly 170 to lock the headband 120, the length of the headband 120 cannot be adjusted at will, making it easier to wear or store. When the locking assembly 170 releases the headband 120, the headband 120 can move with the load 130 relative to the eyeglass body 110 to adjust the length of the headband 120, thereby adjusting the size of the wearing space.

[0182] It should be noted that the "first connecting portion 102" can be "a part of the second belt 124", that is, the "first connecting portion 102" and the "other parts of the second belt 124, such as the belt body" are manufactured as one piece; it can also be an independent component that can be separated from the "other parts of the second belt 124, such as the second connecting body", that is, the "first connecting portion 102" can be manufactured independently and then combined with the "other parts of the second belt 124, such as the belt body" into a whole.

[0183] As shown in FIG19 , some embodiments further provide an image display system 10, comprising a movable platform 200 and the head-mounted display device 100 of any of the above embodiments. The movable platform 200 is equipped with a camera 210. Images captured by the camera 210 are transmitted to the head-mounted display device 100 and displayed on the eyeglass body 110.

[0184] When the image display system 10 is in use, the load 130 can be separated from the eyeglass body 110, increasing the distance between them and making it easier for the user to wear the glasses. Simultaneously, the head-mounted display device 100 can be communicatively connected to the movable platform 200, allowing images captured by the camera 210 to be transmitted to the head-mounted display device 100 for display on the eyeglass body 110. When the head-mounted display device 100 is in the stowed state, the load 130 can be secured to the eyeglass body 110, making it easier for the user to carry the glasses and improving the portability of the image display system 10.

[0185] It can be understood that the user watches the video captured during the movement of the movable platform 200 by wearing the head-mounted display device 100, which not only makes it easier for the user to control the movable platform 200, but also improves the user's viewing experience of watching the captured images.

[0186] In some embodiments, a pan-tilt platform 220 is provided on the movable platform 200, and the photographing device 210 is mounted on the pan-tilt platform 220. In this way, the pan-tilt platform 220 can be used to achieve stabilized photography and improve the photography quality of the photographing device 210.

[0187] In some embodiments, the movable platform 200 includes an aircraft, a ship, a car, or a mobile robot, such as an unmanned aircraft, an unmanned ship, an unmanned car, a mobile robot, and the like.

[0188] Optionally, the movable platform 200 is an unmanned aerial vehicle. The head mounted display device 100 is easy to store, which improves the convenience of the user carrying the unmanned aerial vehicle and the head mounted display device 100, thereby improving the user experience.
