The components of the application described and shown in the drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the application provided in the drawings is not intended to limit the scope of the claimed application, but only represents selected embodiments of the application.

[0019] With the continuous development of mixed reality (MR) technology, MR head-mounted devices are widely used in education and training, medical simulation, industrial design, game entertainment and other fields. The existing MR head-mounted devices usually include optical display components, sensing interaction systems and support structures for wearing, to realize immersive interactive experience of superimposing virtual images on real scenes. Most of the MR head-mounted devices on the market adopt a head-mounted fixing structure, which stably fixes the device on the user's head through a hard or elastic headband. However, there are the following problems in terms of portability, adaptability and multi-scene wearing: large volume, inconvenient to carry, fixed and non-deformable traditional MR head-mounted structure, unable to realize compact storage, users need to carry another storage bag or handheld, affecting convenience. Some products use detachable or folding structures to achieve portability, although the volume can be compressed, but there are many fragile parts, the operation steps are complex, affecting the service life and user experience.

[0020] The utility model aims at providing a portable MR head-mounted holographic device, which aims at solving the problem of single storage mode and poor portability of the existing MR head-mounted device.

[0021] The embodiment discloses a portable MR head-mounted holographic device, which comprises a head-mounted body, an imaging device arranged in the front end of the device for displaying images, a fit pad arranged near the user side, a back pad arranged on the side away from the head-mounted body, a buckle arranged on the back pad, a shaft fixedly arranged on both sides of the head-mounted body, and a pull belt arranged on the left and right sides of the head-mounted body, respectively. The inner end of each pull belt is fixedly connected to the corresponding end of the back pad, the outer end of the pull belt is wound around the shaft arranged on both sides of the head-mounted body, and the pull belt is provided with a buckle hole corresponding to the buckle.

[0022] It can be understood that the head-mounted body refers to the body structure located at the front end of the device, which is internally integrated with an imaging device, such as a miniature display screen, an optical waveguide, or a magnifying lens group, for generating virtual images. The close-fitting pad arranged near the user's side is a flexible pad or foam, which is designed to fit the user's face, and serves to buffer and block light, making the wearing more comfortable.

[0023] The rear pad refers to a structure arranged on the side away from the head-mounted body, which is used to fit the user's back of the head in the head-mounted mode or to fit the user's arm in the arm-mounted mode. The buckle arranged thereon is a protruding or tongue-shaped structure, which is used to be inserted into the buckle hole on the drawstring to realize the positioning of the length of the drawstring.

[0024] The winding shaft refers to a cylindrical shaft or a pulley structure fixedly installed on the left and right sides of the head-mounted body, through which the drawstring is wound, so that the drawstring can be smoothly adjusted in length and changed in direction. The arrangement of the winding shaft can reduce the friction between the drawstring and the body and ensure uniform distribution of the tension of the drawstring.

[0025] The drawstring refers to two long strip-shaped members respectively arranged on the left and right sides, the inner ends of which are fixed to the two ends of the rear pad, and the outer ends of which extend forward after passing through the winding shaft. The drawstring is provided with a plurality of buckle holes along the length direction, and the positions of these holes correspond to the buckles on the rear pad. The length adjustment is realized by inserting the buckles into different hole positions.

[0026] Specifically, in the head-mounted mode, the user wears the head-mounted body in front of the eyes, and the rear pad fits the back of the head. The drawstring extends from the rear pad, changes direction through the winding shaft, and then fits the sides of the head, and is inserted into the buckles on the rear pad, so that the length of the drawstring is adjusted through different hole positions, so that the device is stably fitted to different head circumferences. When it is necessary to carry the device, the user can shorten the drawstring or wind it around the winding shaft to form a ring, and wear it on the arm together with the sleeve in the subsequent claims to realize the arm-mounted mode. This structure realizes the quick switching of the two wearing modes by using simple drawstrings and winding shafts, without the need for complex folding or disassembly mechanisms, which reduces the overall size of the device and enhances the portability and service life.

[0027] In some embodiments, the close-fitting pad on the head-mounted body is a close-fitting curved surface, and the rear pad forms a rear close-fitting curved surface opposite to it, both of which have a concave curve profile in the cross section in the width direction of the device.

[0028] It can be understood that the close-fitting curved surface refers to the arc-shaped design of the close-fitting pad on the head-mounted body, which fits the user's face, and the rear close-fitting curved surface refers to the arc-shaped outer surface of the rear pad, both of which have a concave curve profile in the cross section in the width direction of the device. Such a design forms a hollow arc-shaped area between the close-fitting pad and the rear pad, which can accommodate the user's head and also conform to the curved shape of the arm in the arm-mounted mode. The concave curve profile makes it better to cover the head or arm when worn, improving the close-fitting degree.

[0029] Specifically, the design of the inwardly concave surfaces on the front and back sides makes the head-mounted device conform to the natural curvature of the user's face and back of the head in the head-wearing mode, reducing the sense of oppression and improving the wearing comfort; in the arm-wearing mode, the arc-shaped space between the fitting pad and the back pad can accommodate the arm after the pull strap is tightened, forming an arc-shaped cavity similar to a bracelet, enhancing the arm-wearing fitting degree and effectively preventing sliding. The use of the ergonomic curved profile is suitable for both wearing scenarios, and the portability and comfort are ensured from the structure.

[0030] In some embodiments, the outer ends of the two pull straps are respectively provided with different structures, wherein the outer end of one of the pull straps is provided with a hook surface layer of a magic tape, and the outer end of the other pull strap is provided with a fuzzy surface layer matched with the hook surface layer.

[0031] It can be understood that the hook surface layer and the fuzzy surface layer of the magic tape: the magic tape is a common detachable adhesive structure composed of a hook surface layer and a fuzzy surface layer. When the hook surface layer is pressed against the fuzzy surface layer, it can be temporarily adhered and easily detached. In the device, the outer ends of the two pull straps are respectively provided with different magic tape layers: the outer end of one pull strap is provided with a hook surface layer, and the outer end of the other pull strap is provided with a fuzzy surface layer matched therewith.

[0032] Specifically, when the device needs to be converted into an arm-wearing mode, the user releases a certain length of the left and right pull straps from the shaft and overlaps them with each other, so that the hook surface layer and the fuzzy surface layer are adhered, and stable connection is achieved through friction and buckle engagement. At the same time, by using the adjustability of the magic tape, the user can freely adjust the overlapping length of the two pull straps, thereby adapting to different arm thicknesses and enhancing the firmness and comfort of wearing.

[0033] In some embodiments, a lock buckle is arranged on the pull strap, and the lock buckle is arranged on the side segment of the pull strap, and the insertion direction of the lock buckle is downward along the radial direction of the device.

[0034] It can be understood that the lock buckle refers to a fixing structure arranged on the side of the pull strap, which has a protrusion or a plug for cooperating with the lock buckle seat on the sleeve.

[0035] The side segment refers to the part of the pull strap close to the main body of the head-mounted device, which is usually located below when worn by the user.

[0036] The insertion direction is downward along the radial direction of the device, which means that the direction of the lock buckle inserted into the lock buckle seat of the sleeve is perpendicular to the surface of the pull strap and points downward along the radial direction of the device. Such a direction is beneficial to naturally aligning the lock buckle with the lock buckle seat of the sleeve in the arm-wearing state.

[0037] Specifically, when the user converts the head-mounted display into an arm-wearing mode, the pull strap is tightened, and the lock piece is located on the inner side of the pull strap and close to one end of the main body. At this time, the user wears the sleeve on the arm and inserts the lock piece into the sleeve lock seat. Through the plug-in fixation, the head-mounted display main body and the sleeve form an integral whole, preventing it from slipping off the arm due to movement or vibration. The plug-in direction of the lock piece is selected to be downward along the radial direction, which can enhance the reliability of the clamping by using gravity, and is easy to disassemble.

[0038] In some embodiments, a plurality of buckles are provided on the rear pad, and are arranged equidistantly along the outer edge of the rear pad.

[0039] It can be understood that there is more than one buckle on the rear pad, and usually a plurality of buckles are uniformly spaced along the outer edge of the rear pad. The distance between adjacent buckles is substantially equal, so that it can correspond to the buckle holes on the pull strap.

[0040] Specifically, due to the different head circumferences or arm sizes of different users, the length of the pull strap needs to be adjusted for adaptation. A plurality of equidistantly arranged buckles can be combined with the buckle holes on the pull strap to form multiple adjustment gears. The user can select the appropriate buckle and hole matching position to achieve the tightening or loosening of the pull strap, thereby achieving personalized adaptation. This structure enhances the practicality and comfort of the device and improves the versatility in head-wearing and arm-wearing modes.

[0041] In some embodiments, the buckle hole is provided at the tail end of the pull strap, and the spacing of the buckle hole is consistent with the arrangement distance of the buckle.

[0042] It can be understood that the buckle hole provided at the tail end of the pull strap means that a plurality of through holes or long holes are processed at the distal end of the pull strap for accommodating the buckles on the rear pad. The consistent spacing means that the center distance between the buckle holes is equal to the distance between the buckles on the rear pad, so that any pair of buckles and buckle holes can be accurately buckled.

[0043] Specifically, by providing the buckle hole at the tail end of the pull strap and making the spacing consistent with the buckle position, it is ensured that any pair of buckles and buckle holes can be smoothly plugged in. The user can select different hole positions to adjust the length of the pull strap as needed, so that in the head-wearing mode, it can adapt to different head circumferences; in the arm-wearing mode, it can cooperate with the sleeve to achieve tightening of different arm circumferences. The structure is simple and has a large adjustment range, improving the adaptability.

[0044] In some embodiments, a sleeve for the MR head-mounted display device is also provided, which comprises: a sleeve body, both ends of the sleeve body are provided with fixing pieces; a lock seat is fixedly arranged on the outer surface of the sleeve body, the plug-in direction corresponds to the plug-in direction of the lock piece, and is used for disassembly cooperation with the lock piece.

[0045] It can be understood that the sleeve body is a ring or belt structure, usually made of flexible material, so as to be wrapped around the user's forearm or wrist. The fixing member at both ends of the sleeve body can adopt existing fixing methods such as elastic band, elastic band, buckle, clasp, button or magic tape, etc. Its function is to tighten and fix the sleeve body on the arm in the arm-wearing mode, preventing it from falling off. Different forms of fixing members can be adapted to different arm circumferences, facilitating quick adjustment.

[0046] The lock seat is a female part matched with the lock member on the head-mounted device, and is installed on the outer surface of the sleeve body. The lock seat can be firmly connected to the sleeve body by sewing, hot pressing, gluing or riveting, or can be integrally formed with the sleeve body. The insertion direction of the lock seat corresponds to the insertion direction of the lock member on the side of the pull belt, so that the lock member can be inserted in the correct direction and engaged with it. In use, the sleeve body is wrapped around the user's arm and fixed by the fixing member, and then the lock member of the head-mounted device is aligned with the lock seat and inserted in the predetermined direction to form a reliable mechanical connection. When disassembling, push it out in the opposite direction to release the fixation.

[0047] This structure sets adjustable fixing members at both ends of the sleeve and fixes the lock seat on the outer surface, so that the sleeve can not only firmly fit the user's arm, but also form a firm and easy-to-disassemble connection with the lock member of the head-mounted device, thereby realizing the portable arm-wearing function of the head-mounted device.

[0048] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
