Detailed ways

The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

The AR head-mounted display device is a wearable device that can be worn on the human head for display. It can superimpose virtual information to the real world through computer technology, so that the real environment and virtual objects can be superimposed on the same screen in real time. , realize the mutual complementation of the two kinds of information, carry out visual, auditory and other information interaction, and display the screen in front of the user's eyes through equipment such as helmets and glasses to enhance the user's sense of reality.

In the related art, AR head-mounted display devices generally take the form of glasses. Specifically, as shown in Figures 1-3, the AR glasses include a display module 1 and a frame 3, wherein the frame 3 includes temples 32, and the display module 1 can be arranged on the temple 32, that is, the display module 1 is placed on the side, and further, a lens 4 is also installed on the frame 3, and the lens 4 has no light hood. The image of Group 1 is reflected into the pupils of the human body, allowing the user to see the image.

When the existing AR glasses are used as a visual interaction carrier and the display module 1 is placed on the side, due to technical limitations, the AR glasses are small in structure, and the display module 1 is placed on the side and fixed on the temple 32, so that the display module 1 is placed on the side. Group 1 cannot adjust its own spatial position. Therefore, when people with different head circumferences and different interpupillary distances wear and use it, the image clarity effect is different.

In order to improve the versatility of AR glasses and meet the image presentation effect of people with different head circumferences and interpupillary distances when wearing them, as shown in FIG. 1 and FIG. 2 , this embodiment provides the AR glasses, the AR glasses include: The above-mentioned display module 1 and the mirror frame 3 also include an adjustment mechanism 2, wherein the adjustment mechanism 2 is arranged on the mirror frame 3, and the adjustment mechanism 2 is arranged to be able to adjust the image displayed by the display module 1 to the set field of view within the range.

With this structural design, the image position of the display module 1 in space is adjusted by the adjustment mechanism 2, so that the image of the display module 1 can completely enter the wearer's field of vision, thereby satisfying the requirements of different head circumferences and different pupils. The use of the distance from the wearer improves the versatility and functionality of AR glasses, and increases the scope and scene of the device.

Among them, there are many ways for the adjustment mechanism 2 to adjust the image to the set field of view. For example, the position of the display module 1 in the space can be moved, and then the position of the display module 1 relative to the pupil can be changed, so that the image can be completely into view.

As shown in FIG. 1 and FIG. 3 , this embodiment provides a design method. Specifically, the adjustment mechanism 2 includes a first adjustment assembly 21 , the first adjustment assembly 21 is connected to the mirror frame 3 , and the first adjustment assembly 21 is set to The image position of the image is adjusted in the direction X of the interpupillary distance, and the spatial position of the image of the display module 1 can be changed by using the first adjustment component 21, thereby ensuring that the image can enter the wearer's field of vision.

Adjusting the position of the image in the direction X of the interpupillary distance can be achieved by controlling the two lenses 4 to approach or move away from each other, so as to ensure that the image is reflected into the pupil of the human body, thereby ensuring that the user can see the image. Alternatively, a reflector can also be added to the transmission path of the image of the display module 1 to change the incident angle between the image and the lens 4, so that the user can see the image or the like.

As shown in FIG. 3 and FIG. 4 , in this embodiment, the display module 1 is movably connected to the temple 32 through the first adjustment component 21 . In this structural design, the first adjustment component 21 is arranged on the temple 32 . , it is convenient for the wearer to touch, and the wearer can adjust the position of the image through the first adjustment component 21 without taking off the AR glasses, so as to ensure that the image can completely enter the wearer's field of vision, which is convenient for wearing adjustment of the person.

The display module 1 can be movably connected to the temple 32 through the first adjusting component 21 in various ways, such as sliding. As shown in FIG. 3 and FIG. 4 , in this embodiment, the first adjustment component 21 includes a fixing frame 211 . Specifically, the fixing frame 211 is rotatably connected to the temple 32 , and the display module 1 is installed on the fixing frame 211 . By rotatably connecting the fixing frame 211 to the temple 32, the image position can be finely adjusted, and the image position can be better adjusted to the optimal viewing area to ensure comfort during wearing. In addition, by using the rotation method, only the display module 1 needs to be moved by a small stroke, that is, a large displacement of the image in the interpupillary distance direction X can be realized, and the adjustment range of the image in the interpupillary distance direction X can be improved. to meet the wearing needs of different groups of people.

At the same time, the display module 1 is arranged on the fixing frame 211 , while the display module 1 is assembled, the display module 1 can also be protected, and the structural strength of the display module 1 can be improved. The display module 1 is assembled on the temple 32, which also simplifies the structural design of the AR glasses, and completes the assembly of the display module 1 without many accessories.

The optical path of the image of group 1 (shown by the arrows in Fig. 5 and Fig. 6 ) will follow the movement in the interpupillary distance direction X, that is, the incident angle between the image of the display module 1 and the lens 4 changes, so as to realize the interpupillary distance direction. Adjust the image position of the image on the lens 4 on the X to ensure that it completely enters the wearer's field of vision, so as to meet the needs of people with different head circumferences and different interpupillary distances.

As shown in FIG. 4 , further, in this embodiment, the temple 32 is provided with a first assembly groove 321 , and the fixing frame 211 is rotatably connected to the first assembly groove 321 . By setting the first assembly groove 321 , in the realization of While assembling the fixing frame 211, at least part of the fixing frame 211 can be hidden in the temple 32, which simplifies the structural design of the AR glasses and does not need to occupy too much space on the temple 32, so that the temple 32 can be arranged with other components, making the overall structure of the AR glasses simpler and improving the aesthetics. The display module 1 may include a display element 11 . In order to ensure normal transmission of images, a portion of the display element 11 can protrude from the first assembly groove 321 to prevent the first assembly groove 321 from blocking the image.

Wherein, the display module 1 can be connected to the fixing frame 211 by various methods such as bonding and screw connection. In order to facilitate the assembly of the display module 1 and the fixing frame 211 , as shown in FIGS. 7 and 8 , in this embodiment, the fixing frame 211 may include a fixing body 2111 , and the fixing body 2111 is provided with a cavity 2111 a . , the display module 1 can be directly embedded into the cavity 2111a, and the assembly process is fast and simple.
