All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

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 head-mounted device 1 includes a mirror holder 100 and an augmented reality optical mechanical module 200. The frame 100 is adapted to carry lenses, such as near vision lenses, far vision lenses, and piano lenses, although it is possible to dispense with any lenses.

In addition, the augmented reality optical-mechanical module 200 is not limited to the above structure.

The augmented reality optical-mechanical module 200 is provided with a first connecting piece 102, and the first connecting piece 102 is fixed on the side surface of the augmented reality optical-mechanical module 200. Augmented reality ray apparatus module 200 realizes being connected mirror holder 100's reassembling type through first connecting piece 102, and is concrete, first connecting piece 102 can be for articulating the clamping piece in augmented reality ray apparatus module 200 side, this clamping piece is through turning the centre gripping from top to bottom on mirror holder 100, realize being connected of augmented reality ray apparatus module 200 and mirror holder 100, perhaps first connecting piece 102 is for setting up in the magnet 103 of augmented reality ray apparatus module 200 side, but the mirror holder 100 whole body adopts magnetism to inhale the metallic material preparation, such as iron and alloy etc. to through the absorption of magnet 103 to this magnetism metallic material, it is fixed to the magnetism formula of mirror holder 100 to realize augmented reality ray apparatus module 200.

It should be noted that, because the augmented reality optical-mechanical module 200 is provided with the first connector 102, the augmented reality optical-mechanical module 200 can be used alone, for example, the first connector 102 is a temple or a strap structure, so that the augmented reality optical-mechanical module 200 can be worn on the head of a human body alone to be used; simultaneously augmented reality ray apparatus module 200 also can be fixed in external device and use, here external device includes but not limited to mirror holder 100, for example, external device is the camera, camera equipment such as projector, and first connecting piece 102 is the connection structure who matches with camera equipment, augmented reality ray apparatus module 200 just can connect on these camera equipment through first connecting piece 102 and use like this, again perhaps external device is visual helmet, and first connecting piece 102 is the connection structure who matches with this visual helmet, augmented reality ray apparatus module 200 just so can connect through first connecting piece 102 and use on this visual helmet.

As shown in fig. 1, a hook 201 is disposed at an edge of the augmented reality optical mechanical module 200, the hook 201 may be substantially L-shaped or U-shaped, a flange is disposed on the mirror bracket 100, and the flange is fixed by the hook 201 in a clamping manner, so that the augmented reality optical mechanical module 200 is fixed to the mirror bracket 100 in a clamping manner. Like this, realize that augmented reality optical-mechanical module 200 is fixed to mirror holder 100's joint through couple 201, cooperate first connecting piece 102 to use, can make augmented reality optical-mechanical module 200 more firm to mirror holder 100's fixed effect.

Meanwhile, as a more specific embodiment, the hook 201 can be arranged at the upper edge of the augmented reality optical-mechanical module 200, and the flange is arranged at the upper edge of the mirror bracket 100, so that the connection between the augmented reality optical-mechanical module 200 and the mirror bracket 100 can be more stable in the layout mode, and the change of the relative position between the augmented reality optical-mechanical module 200 and the mirror bracket 100 caused by gravity when the device is worn can be resisted. In another embodiment, the first connector 102 and the hook 201 may also be disposed on the mirror holder 100, so that the mirror holder 100 can be detachably connected to the augmented reality optical mechanical module 200 through the first connector 102, and can also be connected to the augmented reality optical mechanical module 200 through the hook 201 in a clamping manner.

An optimal detachable connection scheme in the application is to set the first connector 102 and the second connector 101 on the augmented reality optical mechanical module 200, so that the first connector 102 and the second connector 101 are mutually matched to realize detachable connection of the augmented reality optical mechanical module 200 and the mirror bracket 100. For example, the first connecting member 102 may be a clip hinged to the side of the augmented reality optical mechanical module 200, and the second connecting member 101 may be a magnet 103 disposed on the side of the augmented reality optical mechanical module 200, so that the clip clamps the mirror holder 100 and the magnet 103 adsorbs the magnetic force of the mirror holder 100, thereby realizing detachable connection of the augmented reality optical mechanical module 200 and the mirror holder 100. For example, the first connecting member 102 is disposed on an elastic buckle of the augmented reality optical mechanical module 200, and the second connecting member 101 is a clip hinged to the side of the augmented reality optical mechanical module 200, and is clamped to the mirror holder 100 by the elastic buckle and the clip is clamped to the mirror holder 100, so as to detachably connect the augmented reality optical mechanical module 200 to the mirror holder 100. Of course, the first connector 102 and the second connector 101 may also be disposed on the mirror bracket 100, and the detachable connection between the augmented reality optical mechanical module 200 and the mirror bracket 100 can also be realized.

Another preferred detachable connection scheme in the present application is to set the second connection part 101 on the mirror holder 100, and set the first connection part 102 on the augmented reality optical mechanical module 200 to match with the second connection part 101, so as to realize the detachable connection of the mirror holder 100 and the augmented reality optical mechanical module 200. For example, the first connector 102 is an elastic buckle, the second connector 101 is a clamping hole which is arranged on the mirror bracket 100 and matched with the first connector 102, and the augmented reality optical mechanical module 200 is detachably connected with the mirror bracket 100 through the elastic buckle; or the first connecting piece 102 is specifically the magnet 103, the second connecting piece 101 is a protruding or embedded in the mirror holder 100, and a magnetic metal block such as iron and its alloy, which is matched with the magnet 103, is attached by magnetic force to realize the detachable connection of the augmented reality optical mechanical module 200 and the mirror holder 100, so as to realize the connection of the augmented reality optical mechanical module 200 to the mirror holder 100. It should be noted that, of course, the positions of the first connecting piece 102 and the second connecting piece 101 are exchanged, that is, the first connecting piece 102 is disposed on the mirror bracket 100, and the second connecting piece 101 on the augmented reality optical mechanical module 200 can also realize the detachable connection between the mirror bracket 100 and the augmented reality optical mechanical module 200.

More preferably, the second connector 101 and the first connector 102 are magnets 103 that are matched with each other as shown in fig. 3, and the augmented reality optical mechanical module 200 can be conveniently mounted on the mirror holder 100 through the magnetic attraction matching between the second connector 101 and the first connector 102. In addition, the magnets 103 engage the frame 100 and/or the augmented reality optomechanical module 200, respectively, to ensure a secure and reliable connection. For example, a recess may be provided in the frame 100 and/or the augmented reality optomechanical module 200, respectively, and then a magnet may be inserted into the recess. Preferably, the recess is filled with an adhesive to more stably engage the magnet to the frame 100 and/or the augmented reality optomechanical module 200. The magnet 103 may also be bonded directly to the frame 100 and/or the augmented reality optomechanical module 200 by an adhesive.

In addition, in the case where the hook 201 is used in cooperation with the magnet 103, the augmented reality optomechanical module 200 can be more stably held with respect to the mirror holder 100, because in the case of only the magnet 103, the augmented reality optomechanical module 200 may be tilted or moved down with respect to the mirror holder 100 due to an external force factor, or the like. After the hook 201 is provided, the augmented reality optical-mechanical module 200 can be prevented from being inclined or moved down relative to the mirror bracket 100 from the mechanical structure, and the augmented reality optical-mechanical module 200 can still be conveniently disassembled and assembled on the mirror bracket 100, which further improves the use experience of the user.

Fig. 3-5 schematically illustrate the arrangement of the magnets 103. Specifically, frame 100 includes two

lens frames

104, 105 and a connecting frame 106 connecting the two

lens frames

104, 105. As such, the number of magnets 103 may be multiple and may be disposed on the lens frames 104, 105 and/or the attachment frame 106. For example, as shown in fig. 3, a magnet 103 is disposed on each of the outer sides of the lens frames 104, 105, and the connecting frame 106 is free of the magnet 103; as shown in fig. 4, a magnet 103 is disposed on the outer side of the lens frames 104 and 105 and the connecting 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 connecting frame 106. The number of the magnets 103 on the augmented reality optical-mechanical module 200 is also multiple, and the magnets 103 on the augmented reality optical-mechanical module 200 are arranged corresponding to the magnets 103 on the mirror bracket 100, that is, the first connecting piece 102 and the second connecting piece 101 are mutually matched. The applicant finds that the magnets 103 arranged in multiple points can prevent the augmented reality optical mechanical module 200 from rotating or shaking relative to the frame 100, so that a user can see a stable image, and the use experience of the head-mounted device 1 is improved. It should be noted that the arrangement of the magnets described herein is merely illustrative, and there may be more or less magnets, and the location of the arrangement may also vary, depending on the actual situation.

The plurality of magnets 103 on the lens frames 104 and 105 are connected to form a straight line. In other embodiments, the magnets 103 of the lens frames 104, 105 are not aligned, such as the magnets 103 are aligned to form a polygon on the lens frames 104, 105. In another embodiment, the magnets 103 of the lens frames 104, 105 are not aligned with the magnets 103 of the attachment frame 106, e.g., the magnets 103 are aligned to form a polygon on the lens frames 104, 105 and the attachment frame 106, which may include a triangle or a quadrilateral. In the case where the line connecting the plurality of magnets 103 is a polygon, the magnets 103 may define a plane. Compared with the case that the connection lines of the magnets 103 are straight lines, the connection between the spectacle frame 100 and the augmented reality optical mechanical module 200 can be more stable by making the connection lines of the magnets 103 be polygons, because for the case that the connection lines of the magnets 103 are straight lines, the augmented reality optical mechanical module 200 is easy to overturn under the action of moment and further fall off under the impact of external force.

In summary, when wearing the head-mounted device 1 of the present application, the augmented reality optical-mechanical module 200 can be installed on the mirror bracket 100 or the augmented reality optical-mechanical module 200 can be detached from the mirror bracket 100 as required. For example, a myopic person may wear the head mounted device 1 with the augmented reality optomechanical module 200 detached to perform a common activity; when needed, the augmented reality optical mechanical module 200 can be mounted on the mirror frame 100 only by the detachable connection of the first connecting piece 102 to the mirror frame 100 or the detachable connection of the second connecting piece 101 and 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 the user.

Further, the augmented reality optical-mechanical 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 sensors may include slam camera, world camera, light sensors, distance sensors, IMU sensors, geomagnetic sensors, and the like. The sensor may also be integrated into the circuit board or may be electrically connected to the circuit board via signal lines. In order to realize signal transmission between the augmented reality optical mechanical module 200 and the signal source, the augmented reality optical mechanical module 200 may further include a wireless module to wirelessly communicate with the signal source; in addition, a signal line and a cable jack and a plug for connecting with a signal source can be arranged on the mirror bracket 100, and a corresponding plug and a corresponding jack are arranged on the augmented reality optical mechanical module 200 to be connected with the signal line on the mirror bracket 100, so that wired communication between the augmented reality optical mechanical module 200 and the signal source is realized. These communication means are only schematic and will not be described herein.

In order to more stably mount the augmented reality opto-mechanical module 200 on the frame 100, the head-mounted device 1 further comprises a bracket 300. One end of the bracket 300 is detachably connected to the frame 100, and 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-mechanical 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-mechanical module 200. Second edge 302 just realizes the bearing to augmented reality optical-mechanical module 200 lower limb like this, and then makes support 300 can bear the partial weight of augmented reality optical-mechanical module 200, alleviates magnet 103's load to make augmented reality optical-mechanical module 200 install on mirror holder 100 more steadily.

The first edge 301 of the bracket 300 is configured with a snap groove 303 to interference snap together with the lower edge of the lens frames 104, 105. Preferably, a friction pattern is configured in the engaging groove 303 to further improve the engaging stability of the holder 300 and the lens frames 104 and 105.

The support 300 may be an opaque strip, such as an opaque plastic sheet. Thus, the support 300 not only can improve the installation stability of the augmented reality optical-mechanical module 200, but also can shield the interference light incident from the lower part of the augmented reality optical-mechanical module 200, which helps further improve the feeling of the user watching the virtual image displayed by the augmented reality optical-mechanical module 200.

In another embodiment, the support 300 may be an opaque strip, that is, the light transmittance of the support 300 is 0, so that light cannot penetrate through the support to block light. And support 300 need not to hide light, can construct transparent or half-reflection half-transparent unit, for example the luminousness that sets up support 300 is between 10% -80%, and support 300 can be for polaroid, the transparent lens or the sunglasses that coat with the light shield layer etc. this moment, through corresponding material selection and technological parameter control, just can make support 300 adjust the luminousness, and then the relative people's eye's of control ambient light volume of getting into, do not harm people's eye when guaranteeing good visual effect. 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 bracket 300 may also be configured in a strip plate or frame shape. The bracket 300 having such a shape is light in weight, and contributes to reducing the weight of the head-mounted device 1, thereby further improving the wearing feeling of the head-mounted device 1.

In other embodiments, a resilient unit 304 is disposed on the first edge 301 and/or the second edge 302 of the stand 300 to support the augmented reality optomechanical module 200. In one embodiment, the elastic unit 304 may be a sponge layer or a flexible rubber layer. The resilient elements 304 may be compressed or compressed, which may compensate for deviations in the position of the magnets 103 on the augmented reality optomechanical module 200 and/or the frame 100, such that the corresponding magnets 103 are aligned as much as possible, and thus ensure the attractive force of the magnets 103.

The frame 100 of the head mounted device 1 may also include temples 120 to facilitate wearing by the user.

See below the augmented reality optomechanical module 200.

Fig. 7 schematically shows an augmented reality opto-mechanical module 200. The augmented reality optical mechanical module 200 includes two

optical modules

2021, 2022, and a module connecting device connected between the two

optical modules

2021, 2022, the module connecting device may be a bridge structure similar to a conventional mirror frame, and the module connecting device using the bridge structure does not adjust the distance between the two

optical modules

2021, 2022 in the subsequent use process, and the module connecting device may also be an adjusting mechanism 210 having an adjusting function, and the augmented reality optical mechanical module 200 further has a sleeve 220, and at least a portion of the adjusting mechanism 210 is disposed in the sleeve 220 to protect the adjusting mechanism 210, in this case, the first connecting member 102 is disposed on the sleeve 220 or the

optical modules

2021, 2022, and the hook 201 may be disposed on the sleeve 220, or disposed on each of the

optical modules

2021, 2022.

The

optical modules

2021, 2022 are used to project a virtual image thereon. The adjusting mechanism 210 is used to adjust the distance between the two

optical modules

2021, 2022 so that it corresponds to the lenses or lens frames 104, 105 of the frame 100, so that the user can see a clearer virtual image, which can further improve the wearing experience of the head-mounted device 1. For example, after the user mounts the augmented reality optical mechanical module 200 to the mirror bracket 100, the distance between the two

optical modules

2021 and 2022 can be adjusted by the adjusting mechanism 210 according to the user's experience, so as to achieve the best experience of using the head-mounted apparatus 1.

Specifically, the adjustment mechanism 210 includes a first adjustment bracket 211 provided on the first optical block 2021, the first adjustment bracket 211 including a first rack gear 213 extending toward the second optical block 2022, a second adjustment bracket 212 provided on the second optical block 2022, the second adjustment bracket 212 including a second rack gear 214 extending toward the first optical block 2021, and a gear 215, a gear shaft 216 of the gear 215 being rotatably provided on the sleeve 220. The first rack 213 and the second rack 214 are disposed opposite to each other, and the gear 215 is interposed between the two

optical modules

2021, 2022 and meshes with the first rack 213 and the second rack 214. Thus, when the gear 215 is rotated, the two

optical modules

2021 and 2022 move synchronously. For example, when the gear wheel 215 is rotated clockwise, the two

optical modules

2021, 2022 will move synchronously towards each other, and when the gear wheel 215 is rotated counterclockwise, the two

optical modules

2021, 2022 will move synchronously away from each other, thus achieving 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, two oppositely disposed 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 track of the two

optical modules

2021 and 2022 during movement is controlled not to be deviated by the guiding effect of the sleeve 220 on the first adjusting frame 211 and the second adjusting frame 212.

Preferably, the gear 215 is a helical gear to which the first and

second racks

213 and 214 are fitted. The helical gear is compared with a straight gear, can have a meshing-in and meshing-out state at every moment, has no meshing blind area, and runs more stably so as 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 and

second racks

213 and 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 relative movement, so that the friction layer provides damping and self-locking capabilities for the adjusting mechanism 210, and further, after the two

optical modules

2021, 2022 are adjusted to a proper distance, the two

optical modules

2021, 2022 can be stably maintained 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 experience of the head-mounted device 1. More preferably, the friction layer may be, for example, a rubber layer or a rough surface disposed on the inner wall of the sleeve 220, which will not be described herein.

In another embodiment, a rubber layer is provided on the meshing surface of the gear 215 and the first and

second racks

213 and 214. This also helps to improve the self-locking capability of the adjustment mechanism 210, and helps to further keep the two

optical modules

2021, 2022 in their proper positions, thereby ensuring that the user sees a clear virtual image, further improving the wearing experience of the head-mounted device 1.

To further facilitate rotation of the gear 215, the adjustment mechanism 210 also includes an adjustment wheel 217. The two 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, it is possible to rotate the adjustment wheel 217 outside the sleeve 220 to rotate the gear wheel 215 and thereby achieve an adjustment of the distance between the two

optical modules
