It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Fig. 1 schematically shows a side view of a head-mounted device 1 according to a first embodiment of the present application. As shown in fig. 1, the headset 1 includes a frame 100 and an augmented reality optical engine module 200. The frame 100 is used to carry lenses, such as near vision lenses, far vision lenses, plano-optic lenses, although any lenses may be omitted.

In addition, the augmented reality optical machine module 200 may not be limited to the above-described structure.

The first connecting piece 102 is disposed on the augmented reality optical machine module 200, and the first connecting piece 102 is fixed on a side surface of the augmented reality optical machine module 200. The augmented reality optical machine module 200 realizes the dismouting type connection to the mirror holder 100 through the first connecting piece 102, specifically, the first connecting piece 102 can be the clamping piece of articulating in the side of the augmented reality optical machine module 200, this clamping piece passes through to flip the centre gripping from top to bottom on the mirror holder 100, realize the connection of the augmented reality optical machine module 200 and the mirror holder 100, or the first connecting piece 102 is for setting up in the magnet 103 of the side of the augmented reality optical machine module 200, but and the mirror holder 100 whole adopts the magnetism to inhale metallic material preparation, such as iron and alloy etc. to adsorb this magnetic metallic material through magnet 103, realize that the magnetism of the augmented reality optical machine module 200 to the mirror holder 100 is inhaled fixedly.

It should be noted that, because the first connector 102 is disposed on the augmented reality optical machine module 200, the augmented reality optical machine module 200 can be used alone, for example, the first connector 102 is in a structure of a glasses leg or a binding band, so that the augmented reality optical machine module 200 can be worn on the head of a human body alone to be used; meanwhile, the augmented reality optical machine module 200 can also be fixed on an external device for use, where the external device includes, but is not limited to, a frame 100, for example, the external device is a camera, a projector, and other image capturing devices, and the first connector 102 is a connection structure matched with the image capturing devices, so that the augmented reality optical machine module 200 can be connected to the image capturing devices through the first connector 102 for use, or the external device is a visual helmet, and the first connector 102 is a connection structure matched with the visual helmet, so that the augmented reality optical machine module 200 can be connected to the visual helmet through the first connector 102 for use.

As shown in fig. 1, a hook 201 is disposed at an edge of the augmented reality optical machine module 200, the hook 201 may be generally L-shaped or U-shaped, a flange is disposed on the frame 100, and the augmented reality optical machine module 200 is fastened and fixed on the frame 100 by fastening the hook 201 to the flange. Like this, realize through couple 201 that the joint of augmented reality ray apparatus module 200 to mirror holder 100 is fixed, cooperate first connecting piece 102 to use, can make the fixed effect of augmented reality ray apparatus module 200 to mirror holder 100 more firm.

Meanwhile, as a more specific implementation manner, the hook 201 may be disposed at the upper edge of the augmented reality optical machine module 200, and the flange is disposed at the upper edge of the frame 100, so that the connection between the augmented reality optical machine module 200 and the frame 100 is more stable in a layout manner, so as to resist the change of the relative positions of the augmented reality optical machine module 200 and the frame 100 caused by gravity when the device is worn. In another embodiment, the first connector 102 and the hook 201 may also be disposed on the frame 100, so that the frame 100 can be detachably connected with the augmented reality optical machine module 200 through the first connector 102 and can also be clamped with the augmented reality optical machine module 200 through the hook 201.

One preferred detachable connection scheme in the application is to set up the first connecting piece 102 and the second connecting piece 101 on the augmented reality optical machine module 200, so that the first connecting piece 102 and the second connecting piece 101 are mutually matched, and the detachable connection between the augmented reality optical machine module 200 and the frame 100 is realized. For example, the first connecting piece 102 may be a clip hinged to a side of the augmented reality optical machine module 200, and the second connecting piece 101 may be a magnet 103 disposed on a side of the augmented reality optical machine module 200, and the detachable connection between the augmented reality optical machine module 200 and the frame 100 is realized by clamping the frame 100 by the clip and magnetic attraction of the magnet 103 to the frame 100. For example, the first connecting piece 102 is disposed on an elastic buckle of the augmented reality optical machine module 200, and the second connecting piece 101 is a clip hinged to a side surface of the augmented reality optical machine module 200, and is clamped to the frame 100 through the elastic buckle and clamped to the frame 100, so as to realize detachable connection between the augmented reality optical machine module 200 and the frame 100. Of course, the first connecting piece 102 and the second connecting piece 101 may be disposed on the frame 100, and the augmented reality optical machine module 200 and the frame 100 can be detachably connected.

Another preferred detachable connection scheme in the present application is to provide the second connector 101 on the frame 100, and provide the first connector 102 on the augmented reality optical machine module 200 to match with the second connector 101, so as to realize the detachable connection between the frame 100 and the augmented reality optical machine module 200. For example, the first connecting piece 102 is an elastic buckle, the second connecting piece 101 is a clamping hole arranged on the frame 100 and matched with the first connecting piece 102, and the detachable connection between the augmented reality optical machine module 200 and the frame 100 is realized through elastic clamping; or the first connecting piece 102 is specifically a magnet 103, the second connecting piece 101 is a magnetic metal block which is convexly arranged or embedded in the glasses frame 100 and matched with the magnet 103, such as iron, alloy thereof and the like, and the dismounting connection between the augmented reality optical machine module 200 and the glasses frame 100 is realized through magnetic attraction, so that the connection of the augmented reality optical machine module 200 to the glasses frame 100 is realized. It should be noted that, of course, the positions of the first connector 102 and the second connector 101 are exchanged, that is, the first connector 102 is disposed on the frame 100, and the second connector 101 is disposed on the augmented reality optical module 200, so that the frame 100 and the augmented reality optical module 200 can be detachably connected.

More preferably, the second connecting piece 101 and the first connecting piece 102 are mutually matched magnets 103 shown in fig. 3, and the installation of the augmented reality optical machine module 200 on the frame 100 can be conveniently realized through the mutual magnetic attraction matching of the second connecting piece 101 and the first connecting piece 102. In addition, the magnets 103 are respectively embedded on the frame 100 and/or the augmented reality optical machine module 200 to ensure firmness and reliability. For example, grooves are provided in the frame 100 and/or the augmented reality optical engine module 200, respectively, and then magnets are embedded in the grooves. Preferably, the grooves are filled with an adhesive to more stably engage the magnets on the frame 100 and/or the augmented reality optical engine module 200. The magnets 103 may also be directly bonded to the frame 100 and/or the augmented reality optical module 200 by an adhesive.

In addition, in the case where the hook 201 is used in combination with the magnet 103, the augmented reality optical machine module 200 can be more stably held with respect to the frame 100, because the augmented reality optical machine module 200 may be deflected or moved down with respect to the frame 100 due to external force factors or the like in the case of only the magnet 103. After the hook 201 is provided, the deflection or downward movement of the augmented reality optical machine module 200 relative to the frame 100 can be avoided mechanically, and the augmented reality optical machine module 200 can be conveniently detached from the frame 100, which further improves the use feeling of the user.

Fig. 3-5 schematically show the arrangement of the magnets 103. Specifically, the frame 100 includes two lens frames 104, 105 and a connecting frame 106 that connects the two lens frames 104, 105. In this way, the number of magnets 103 may be plural and may be disposed on the lens frames 104, 105 and/or the connecting frame 106. For example, as shown in fig. 3, one magnet 103 is arranged outside each of the lens frames 104, 105, and the magnet 103 is not provided on the connection frame 106; as shown in fig. 4, one magnet 103 is arranged on each of the outer sides of the lens frames 104, 105 and the connection frame 106; as shown in fig. 5, one magnet 103 is disposed outside each of the lens frames 104 and 105, and two magnets 103 are disposed on the connection frame 106. The number of the magnets 103 on the augmented reality optical machine module 200 is also plural, and the magnets 103 on the augmented reality optical machine module 200 are arranged corresponding to the magnets 103 on the frame 100, that is, the first connecting piece 102 and the second connecting piece 101 are mutually matched. The applicant has found that the multi-point arrangement of the magnets 103 prevents the augmented reality optical engine module 200 from rotating or rocking relative to the frame 100 so that a user can see a stable image, improving the feel of the headset 1 in use. It should be noted that the arrangement of magnets described herein is illustrative only, and that there may be more or fewer magnets and the placement positions may vary depending on the actual situation.

The pattern formed by connecting the plurality of magnets 103 on the lens frames 104, 105 is a straight line. In other embodiments, the plurality of magnets 103 on the lens frames 104, 105 are not wired in a straight line, such as the plurality of magnets 103 wired on the lens frames 104, 105 forming a polygon. In another embodiment, the magnet 103 on the lens frame 104, 105 is not in line with the magnet 103 on the connecting frame 106, e.g., the magnet 103 is in line with the lens frame 104, 105 and the connecting frame 106 to form a polygon, which may include a triangle or a quadrilateral. In the case where the line connecting the plurality of magnets 103 is polygonal, the magnets 103 may define a plane. The connection between the frame 100 and the augmented reality optical machine module 200 can be more stable by connecting the plurality of magnets 103 in a polygon than in the case where the plurality of magnets 103 are connected in a straight line, because the augmented reality optical machine module 200 is easily turned over by a moment and then falls down when an external force is applied to the case where the plurality of magnets 103 are connected in a straight line.

To sum up, when wearing the head-mounted device 1 of the present application, the augmented reality optical module 200 may be mounted on the frame 100 or the augmented reality optical module 200 may be detached from the frame 100 as needed. For example, a myopic person may wear the headset 1 with the augmented reality optical engine module 200 removed for ordinary activities; when needed, the augmented reality optical machine module 200 can be installed on the frame 100 only through the detachable connection of the first connecting piece 102 to the frame 100 or the detachable connection of the second connecting piece 101 to the first connecting piece 102, so that the experience of the head-mounted device can be experienced. In the whole process, the glasses do not need to be replaced, which greatly facilitates the use of users.

Further, the augmented reality optical engine module 200 is used for projecting virtual world information, and may include, for example, a circuit board, a computing unit integrated on the circuit board, an optical module, a sensor, and the like. The sensor may include a slam camera, a world camera, a light sensor, a distance sensor, an IMU sensor, a geomagnetic sensor, etc. The sensor may also be integrated onto the circuit board or may be electrically connected to the circuit board via signal lines. To enable signal transfer between the augmented reality optical engine module 200 and the signal source, the augmented reality optical engine module 200 may further include a wireless module to wirelessly communicate with the signal source; in addition, a signal wire, a cable socket and a plug for connecting with a signal source can be arranged on the glasses frame 100, and a corresponding plug and a corresponding socket are arranged on the augmented reality optical machine module 200 to be connected with the signal wire on the glasses frame 100, so that wired communication between the augmented reality optical machine module 200 and the signal source is realized. These communication modes are merely illustrative and will not be described in detail herein.

In order to mount the augmented reality optical engine module 200 on the frame 100 more stably, the head mounted device 1 further comprises a stand 300. When the bracket 300 is connected to the frame 100, the edge of the other end of the bracket 300 is in close contact with the edge of the augmented reality optical module 200, for example, a first edge 301 of the bracket 300 along the length direction thereof is detachably connected to the lower edges of the lens frames 104 and 105, and a second edge 302 parallel to and opposite to the first edge 301 is in close contact with the lower edge of the augmented reality optical module 200. Thus, the second edge 302 can support the lower edge of the augmented reality optical machine module 200, so that the bracket 300 can bear part of the weight of the augmented reality optical machine module 200, and the load of the magnet 103 is reduced, so that the augmented reality optical machine module 200 is more stably mounted on the frame 100.

The first edge 301 of the bracket 300 is configured with a snap-in groove 303 to interference snap-in with the lower edges of the lens frames 104, 105. Preferably, friction patterns are configured in the clamping grooves 303 to further improve the clamping stability of the bracket 300 and the lens frames 104 and 105.

The stand 300 may be an opaque strip-shaped plate, such as an opaque plastic plate. In this way, the bracket 300 not only can improve the installation stability of the augmented reality optical machine module 200, but also can shield the interference light incident from the lower side of the augmented reality optical machine module 200, which helps to further improve the experience of the user in viewing the virtual image displayed by the augmented reality optical machine module 200.

In another embodiment, the support 300 may be an opaque strip, i.e. the light transmittance of the support 300 is 0, so that the light cannot penetrate and the light can be blocked. When the support 300 does not need to shade light, the support 300 can be constructed as a transparent or semi-reflective semi-transparent unit, for example, the light transmittance of the support 300 is set to be between 10% and 80%, at this time, the support 300 can be a polaroid, a transparent lens coated with a shading layer, a sunglasses or the like, the light transmittance of the support 300 can be adjusted through corresponding material selection and process parameter control, the entering amount of ambient light relative to human eyes is further controlled, and the human eyes are not damaged while good visual effect is ensured. Meanwhile, the light transmittance can be adjusted by the angle of the light transmission axis of the polarizing film disposed at both sides of the transflective unit, which is well known to those skilled in the art, and will not be described herein.

In addition, the stand 300 may be constructed in a strip shape or a frame shape. The cradle 300 of this shape is light in weight, contributing to weight reduction of the head-mounted device 1, thereby further improving the wearing feeling of the head-mounted device 1.

In further embodiments, a resilient unit 304 is provided on the first edge 301 and/or the second edge 302 of the stand 300 to support the augmented reality optical machine module 200. In one embodiment, the elastic unit 304 may be a sponge layer or a flexible rubber layer. The elastic unit 304 may be compressed or compressed, which may compensate for deviations in the fixed positions of the magnets 103 on the augmented reality optical bench module 200 and/or the frame 100, so that the corresponding magnets 103 are aligned as much as possible, and thus the suction force of the magnets 103 is ensured.

The frame 100 of the headset 1 may also include temples 120 to facilitate wear by the user.

The augmented reality ray apparatus module 200 is seen below.

Fig. 7 schematically shows an augmented reality opto-mechanical module 200. The augmented reality optical bench module 200 comprises two optical modules 2021, 2022, a module connecting device connected between the two optical modules 2021, 2022, the module connecting device can be a nose bridge structure similar to a conventional frame, the distance between the two optical modules 2021, 2022 is not adjusted in the subsequent use process, the module connecting device can also be an adjusting mechanism 210 with an adjusting function, and the augmented reality optical bench module 200 is further provided with a sleeve 220, the protection of the adjusting mechanism 210 is realized by arranging at least part of the adjusting mechanism 210 in the sleeve 220, in which case, the first connecting piece 102 is arranged on the sleeve 220 or the optical modules 2021, 2022, and the hook 201 can be arranged on the sleeve 220 or one place on each of the optical modules 2021, 2022.

The optical modules 2021, 2022 are used to project virtual images thereon. The adjustment mechanism 210 is used to adjust the distance between the two optical modules 2021, 2022 so that it corresponds to the lenses or frames 104, 105 on the frame 100, so that the user sees a clearer virtual image, which can further improve the wearing feeling of the head-mounted device 1. For example, after the user installs the augmented reality optical module 200 on the frame 100, the distance between the two optical modules 2021, 2022 can be adjusted by the adjusting mechanism 210 according to the user's own experience, so as to achieve the best use experience of the head-mounted device 1.

Specifically, the adjustment mechanism 210 includes a first adjustment frame 211 disposed on the first optical module 2021, the first adjustment frame 211 includes a first rack 213 extending toward the second optical module 2022, a second adjustment frame 212 disposed on the second optical module 2022, the second adjustment frame 212 includes a second rack 214 extending toward the first optical module 2021, and a gear 215, and a gear shaft 216 of the gear 215 is rotatably disposed on the sleeve 220. The first rack 213 and the second rack 214 are disposed opposite to each other, and the gear 215 is disposed between the two optical modules 2021, 2022 and is engaged with the first rack 213 and the second rack 214. Thus, when the gear 215 is rotated, the two optical modules 2021, 2022 move synchronously. For example, when the gear 215 is rotated clockwise, the two optical modules 2021, 2022 are moved towards each other synchronously, and when the gear 215 is rotated counter-clockwise, the two optical modules 2021, 2022 are moved away from each other synchronously, thus enabling adjustment of the distance between the two optical modules 2021, 2022. Meanwhile, it should be noted that the inner wall of the sleeve 220 is adapted to the first adjusting frame 211 and the second adjusting frame 212, specifically, the two opposite ports of the sleeve 220 are respectively sleeved with the first adjusting frame 211 and the second adjusting frame 212, so that the first adjusting frame 211 and the second adjusting frame 212 can perform telescopic movement relative to the sleeve 220, that is, the guiding function of the sleeve 220 on the first adjusting frame 211 and the second adjusting frame 212 is achieved, so that the track of the two optical modules 2021 and 2022 is controlled not to deviate when moving.

Preferably, the gear 215 is a helical gear, and the first rack 213 and the second rack 214 are adapted to the helical gear. Compared with a straight gear, the helical gear can have a meshing-in and meshing-out state at all times, has no meshing blind area, and can run more stably to play a role in stepless speed regulation.

In another embodiment, a friction layer is provided on the inner wall of the sleeve 220, and the first rack 213 and the second rack 214 are in close contact with the friction layer. When the adjusting mechanism 210 starts to move, the first rack 213 and the second rack 214 generate friction force with the friction layer respectively due to the relative movement, so that the friction layer provides damping and self-locking capability for the adjusting mechanism 210, and further after the two optical modules 2021 and 2022 are adjusted to a proper distance, the two optical modules 2021 and 2022 can be stably kept in the current position without shaking or deviating from the position along with the movement of the user, thereby ensuring that the user sees a clear virtual image and further improving the wearing feeling of the head-mounted device 1. More preferably, the friction layer may be, for example, a rubber layer or a roughened surface disposed on the inner wall of the sleeve 220, which will not be described herein.

In further embodiments, a rubber layer is provided on the engagement surface of the gear 215 with the first rack 213 and the second rack 214. This also helps to improve the self-locking ability of the adjustment mechanism 210, helping to further keep the two optical modules 2021, 2022 in their proper position, so that a clear virtual image can be ensured to be seen by the user, further improving the wearing feel of the head-mounted device 1.

To further facilitate rotation of the gear 215, the adjustment mechanism 210 also includes an adjustment wheel 217. Both ends of the gear shaft 216 are fixedly connected with the adjusting wheel 217 and the gear 215, respectively, and at least part of the adjusting wheel 217 radially protrudes out of the sleeve 220. In this way, the adjustment wheel 217 can be turned outside the sleeve 220 to turn the gear 215 and thereby achieve adjustment of the distance between the two optical modules 2021, 2022. In this way, after the user installs the augmented reality optical machine module 200 on the frame 100, the user can conveniently rotate the adjusting wheel 217 according to his own feeling to adjust the distance between the two optical modules 2021, 2022, so as to achieve the best use feeling of the head-mounted device 1.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art.
