[0024] The utility model provides a head-mounted device, which is used to display the environmental image blocked by the support module on the display component by arranging a display component on the inner side of the support module and arranging an image acquisition component on the outer side of the support module, thereby reducing the occlusion of the user's side field of view by the support module and improving the field of view provided by the head-mounted device.

[0025] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the utility model described here, for example, can be implemented in an order other than those illustrated or described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] like Figure 1 As shown, the embodiment of the utility model provides a head mounted device, specifically comprising:

[0027] Support module 10, support module 10 is used to provide wearing support;

[0028] An image display module 20, which is mounted on the support module and is used to display target image information in the user's field of view;

[0029] The environment compensation module 30 includes an environment display component 31 disposed inside the support module and an environment acquisition component 32 disposed outside the support module. The environment display component 31 is used to display the environment image acquired by the environment acquisition component 32 .

[0030] In the present invention, an environment display component 31 is arranged on the inner side of the support module 10, and an environment acquisition component 32 is arranged on the outer side of the support module 10, so that the environment image blocked by the support module 10 is displayed on the environment display component 32, thereby reducing the blockage of the user's side vision by the support module 10 and improving the field of view provided by the head-mounted device.

[0031] It can be understood that the environmental image collected by the environment acquisition component 32 is processed by the image processing module to ensure that the image is clear and stable, and the clear and stable image processed by the image processing module is transmitted to the environment display component 31 in real time, so that when the user wears the head-mounted device, he can still observe the environment on the side of the head-mounted device, compensating for the loss of vision caused by the occlusion of the support module 10.

[0032] For example, the head-mounted device may be an AR glasses. In this case, the support module 10 may be a frame, which mainly includes a frame and two temples located on opposite sides of the frame. The frame is mainly used to install and fix the lenses, and the two temples are mainly used to provide support for wearing the AR glasses. The image display module may include a lens, the environment display component 31 may be a display screen, and the environment acquisition component 32 may be a camera. Figure 1 As shown, the environmental image on the side of the AR glasses is collected by a camera arranged on the outside of the AR glasses, and is processed by an image processing module to ensure that the image is clear and stable. The processed image is displayed in real time on the display screen inside the AR glasses.

[0033] It should be noted that the current mainstream head-mounted device can be an AR glasses, which can superimpose the real-world environment image and the computer-generated virtual content image (i.e., the target image information mentioned above), and then be observed by the human eye. Therefore, when the temples of the AR glasses are thicker, they will block the side vision of the human eye, resulting in the human eye being unable to observe the side environment image. The AR glasses in the embodiment of the present application can display the surrounding environment image in real time through the camera and display screen set on the temples (close to the frame), thereby improving the wearer of the AR glasses' ability to perceive the environment and improving the safety of the AR glasses.

[0034] In a possible implementation, Figure 1 As shown, the support module 10 includes a first support assembly 11 and a second support assembly 12. The first support assembly 11 is provided with a first connection portion 111, and the second support assembly 12 is provided with a second connection portion 121. The first connection portion 111 is connected to the second connection portion 121, and the environment display assembly 31 and the environment collection assembly 32 are respectively installed on the first connection portion 111.

[0035] It should be noted that the support module 10 includes two components, namely a first support component 11 and a second support component 12. When the head-mounted device is AR glasses, the main body of the first support component 11 is the frame, and the second support component 12 is the temples. Therefore, there are two temples, and the frame and the two temples are movably connected. For example, the frame and the two temples are connected by hinges so that the two temples can be folded up for easy storage. That is, the support module 10 may specifically include two second support components 12, and the two second support components 12 are both provided with a second connecting portion 121. Two opposite sides of the first support component 12 are respectively provided with a first connecting portion 111, and each first connecting portion 111 is respectively connected to a corresponding second connecting portion 121.

[0036] It is understandable that the two temples of the AR glasses are connected to the frame respectively. When the second support assembly 12 of the AR glasses cannot be folded, for example, it can be connected by a snap-on connection. Then, the first connection portion 111 and the second connection portion 121 are fixedly connected. When the first connection portion 111 and the second connection portion 121 are movably connected, for example, hinged, the two second support assemblies 12 can be folded when not in use for easy storage.

[0037] In a possible implementation, Figure 1 As shown, the environment display component 31 is a flexible screen, which is laid on the inner surface of the first connecting part 111.

[0038] It should be noted that, when the head-mounted device is an AR glasses, the inner surface of the first connecting portion 111 specifically refers to a side surface that contacts the user's head or faces the user's head when the user wears it. When the inner surface of the first connecting portion 111 has a certain curvature or angle, in order to ensure that the environmental display component 31 has a sufficiently large display area, it is necessary to increase the coverage area of ​​the environmental display component 31 on the first connecting portion 111. Therefore, a flexible screen can be used as a display screen to better fit the inner surface of the first connecting portion 111 of different shapes. In addition, the environmental display component 31 can also use other forms of display screens, for example, an environmental display component 31 composed of matrixed display units, as long as the environmental display component 31 can cover the inner surface of the first connecting portion 111 of different shapes or angles.

[0039] The utility model displays the image captured by the image acquisition component 32 arranged on the outside of the first connecting part 111 through the environment display component 31 arranged on the inner side of the first connecting part 111, that is, compensates for the environmental image on the side of the wearer's eye, provides the wearer with a side field of view, reduces the occlusion of the user's side field of view by the support module, and improves the field of view provided by the head-mounted device.

[0040] In a possible implementation, Figure 1 As shown, the environment collection component 32 is a camera, and the camera is installed on the outer surface of the first connecting portion 111.

[0041] It should be noted that, when the head-mounted device is an AR glasses, the outer surface of the first connecting portion 111 specifically refers to the side surface that does not contact the user's head or faces away from the user's head when the user wears it. When the environment acquisition component 32 is a camera, it is arranged at the connection between the temple and the frame of the AR glasses, and is arranged on the outside away from the wearer's head (i.e., the outer surface of the first connecting portion 111), so as to facilitate the acquisition of environmental images on the left and right sides of the AR glasses and display them on the environment display component 31.

[0042] In addition, the camera can be a fixed-focus camera to ensure that the captured image can cover the wearer's visual field area blocked by the temple. According to the specifications of the camera, the camera can also be set at other positions of the temple, as long as the camera can capture images of the area blocked by the temple. For example, when a panoramic camera is used, the position of the camera can be moved from the outer surface of the first connecting portion 111 in the first support component 11 to other positions, for example, set at a position close to the second connecting portion 121 on the second support component 12. The specific details are not limited here, and it only needs to be located on the outer side of the second support component 12.

[0043] The utility model displays the image captured by the image acquisition component 32 arranged on the outside of the first connecting part 111 through the environment display component 31 arranged on the inner side of the first connecting part 111, that is, compensates for the environmental image on the side of the wearer's eye, provides the wearer with a side field of view, reduces the occlusion of the user's side field of view by the support module, and improves the field of view provided by the head-mounted device.

[0044] In a possible implementation, Figure 1 As shown, the first supporting assembly 11 is also provided with a mounting portion 111, which is fixed at one end of the first connecting portion 111 away from the second connecting portion 121, and the mounting portion 111 and the first connecting portion 112 are arranged at a preset angle, and the image display module 20 is partially installed on the mounting portion 111.

[0045] It should be noted that when the head-mounted device is an AR glasses, the mounting portion 112 of the first support assembly 11 is a frame. To facilitate the partial installation of the image display module 20, a corresponding mounting groove may be provided on the mounting portion 112. The mounting groove may be in various forms, such as a supporting mounting groove or an embedded mounting groove. When the mounting groove is an external mounting groove, the mounting groove may be provided on the inner side of the mounting portion 112, and the mounting groove and the lower edge of the frame form a supporting mounting groove. Part of the structure of the image display module 20 (such as a waveguide) may be installed in the supporting mounting groove along the direction of gravity, and the supporting mounting groove fixes the image display module 20 on the mounting portion 112 (i.e., the frame).

[0046] When the mounting groove is an embedded mounting groove, the mounting groove can be set in the middle of the mounting portion 112 (i.e., the mirror frame), and the mounting groove is an embedded mounting groove set along the inner side of the through hole on the mounting portion 112 (i.e., the mirror frame). Part of the structure of the image display module 20 (such as the waveguide plate) can be installed in the embedded mounting groove, and the embedded mounting groove fixes the image display module 20 on the mounting portion 112 (i.e., the mirror frame).

[0047] It is understandable that part of the structure of the image display module 20 can also be fixedly connected to the mounting portion 112 by bonding or snap connection. The preset angle mentioned in the above example is preferably 90 degrees, so that the mounting portion 111 and the first connecting portion 112 are arranged at a right angle.

[0048] In a possible implementation, Figure 1 As shown, the image display module 20 includes an image generation component (not shown) for generating target image information and an image display component 21 for displaying the target image information in the user's field of view. The first connecting portion 111 is provided with an inner cavity (not shown), the image generation component is installed in the inner cavity, and the image display component 21 is installed in the mounting portion. Further, the inner surface of the mounting portion 112 is provided with an inner cavity hole (not shown) connected to the inner cavity, and the image generation component projects the generated target image information to the image display component on the mounting portion through the inner cavity hole.

[0049] It should be noted that, when the head-mounted device is an AR glasses, the image generating component of the AR glasses is arranged at the connection between the frame and the temples, and a first mounting portion 111 is provided at both ends of the frame. The interior of the first mounting portion 111 is a hollow cavity, and an inner cavity hole is formed with the frame. The image generating component (specifically, it may be an optical machine) is arranged in the inner cavity, and the light emitting direction of the image generating component (specifically, it may be an optical machine) is opposite to the inner cavity hole, that is, the light emitted by the image generating component (specifically, it may be an optical machine) passes through the inner cavity hole and is projected onto the image display component 21 (specifically, it may include a waveguide plate), thereby completing the display of the virtual content image in the AR glasses.

[0050] It can be understood that an adjustment component can also be provided on the inner cavity hole for adjusting the light emission direction of the image generating component (specifically, it can be an optical machine), so that the direction of the light emitted through the inner cavity hole can be adjusted according to the transformation of the adjustment component, thereby meeting the usage needs of people with different head circumferences or pupil distances, so that each wearer can clearly project the light emitted by the image generating component onto the image display component 21 (specifically, it can include a waveguide), thereby ensuring that the image displayed on the AR glasses is clear and stable, and improving the wearer's usage experience.

[0051] In a feasible implementation, the head mounted device further includes a main control circuit board (not shown), which is mounted on the support module 10 and is electrically connected to the image display module 20 and the environment compensation module 30 respectively.

[0052] It can be understood that the main control circuit board can be specifically built into the inner cavity of one of the first connecting parts 111, so that it can be electrically connected to the image display module 20 and the environmental compensation module 30 respectively. The electrical connection between the main control circuit board and the image display module 20 mainly refers to the electrical connection between the main control circuit board and the image generation component. Since the head-mounted device also needs to be equipped with an image processing module for processing the environmental image collected by the environmental acquisition component 32 and transmitting it to the environmental display component 31, the electrical connection between the main control circuit board and the environmental compensation module 30 mainly refers to the electrical connection between the main control circuit board and the image processing module, the environmental display component 31, and the environmental acquisition component 32 respectively.

[0053] In addition, it should be noted that the image processing module can be specifically arranged in a cavity of a temple. The image processing module can also be integrated with other control circuits, for example, the image processing module is integrated into a main control circuit board, and the environment image display is completed through the main control circuit board.

[0054] In a feasible implementation manner, the head mounted device further includes a power module (not shown), which is mounted on the support module 10 and is used to provide working power to the image display module 20 and the environment compensation module 30 .

[0055] It should be noted that the power module is arranged in the cavity of the support module 10. When the head-mounted device is AR glasses, the power module is generally arranged in the cavity of the temples.

[0056] It is understandable that, in addition to the battery, the power module also needs to be equipped with a battery control circuit board for charging and discharging the battery, and the battery control circuit board is set in the cavity of one temple, and the battery is set in the cavity of the other temple. Among them, the battery control circuit board can also be integrated, that is, the corresponding functions are integrated on the main control circuit board, and the battery charging and discharging management is completed through the main control circuit board.

[0057] Finally, it should be noted that the above embodiments are only specific implementation methods of the utility model, which are used to illustrate the technical solution of the utility model, rather than to limit it. The protection scope of the utility model is not limited thereto. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art should understand that any technician familiar with the technical field can still modify the technical solution recorded in the above embodiments within the technical scope disclosed by the utility model, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solution deviate from the spirit and scope of the technical solution of the embodiment of the utility model, and should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
