[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0035] In existing technologies, to increase the versatility of head-mounted display devices, the nose bridge portion that contacts the user's nose is typically set to the maximum size. Then, by adding nose pads of different sizes and heights or using deformable nose pad wires, it can accommodate users with different nose bridge heights. However, using detachable nose pads requires preparing different sizes in advance, and storage and replacement are inconvenient; while using nose pad wires makes it difficult to ensure the consistency of the deformation of two nose pad wires, affecting the image display effect of the head-mounted display device.

[0036] To address the aforementioned problems, this embodiment provides a head-mounted display device, see reference. Figures 1-3It includes the lens body 10, temples, optical module, connectors and nose pads.

[0037] Furthermore, the lens body 10 includes a left lens box 101 and a right lens box 102. The left lens box 101 and the right lens box 102 each have a receiving space inside. A micro display panel and an optical module corresponding to the micro display panel are arranged in the receiving space. The optical module can project the display image of the corresponding micro display panel to the user's viewing side. The micro display panel and optical module in the left lens box 101 are used for left eye imaging, and the micro display panel and optical module in the right lens box 102 are used for right eye imaging.

[0038] It should be noted that the optical module may include optical elements such as convex lenses, curved mirrors, and semi-transparent mirrors, depending on its type. In one embodiment, this invention uses a birdbath-type optical module, including a convex lens positioned below the microdisplay panel, a curved mirror positioned away from the user's viewing side, and a semi-transparent mirror positioned between the user's viewing side and the curved mirror. Light from the microdisplay panel passes through the convex lens and is reflected by the semi-transparent mirror to the curved mirror, which then reflects the light again, allowing it to pass through the semi-transparent mirror to reach the user's viewing side. External light can also enter the user's eye through the curved mirror and the semi-transparent mirror, creating a superimposed display effect of the displayed image and the surrounding environment. Of course, the optical module can also be other types of optical modules besides the birdbath type, and this invention does not limit this.

[0039] It should be noted that the shapes of the left lens case 101 and the right lens case 102 can be set as ellipsoids, cubes, non-uniform spheres, etc., and there is no limitation here. Furthermore, a connecting rod 12 can be provided between the left lens case 101 and the right lens case 102 to connect the left lens case 101 and the right lens case 102 and form a nose bridge.

[0040] Furthermore, the temples include a left temple 21 and a right temple 22. The left temple 21 is rotatably connected to the outside of the left lens case 101, and the right temple 22 is rotatably connected to the outside of the right lens case 102. When the head-mounted display device is not in use, the left temple 21 and the right temple 22 are folded inward for storage, and when the head-mounted display device is to be used, the left temple 21 and the right temple 22 are unfolded outward.

[0041] Furthermore, the connectors include a left connector 31 and a right connector 32, which are respectively disposed on the inner sides of the left mirror housing 101 and the right mirror housing 102. The left connector 31 and the right connector 32 are symmetrically arranged, and each of the left connector 31 and the right connector 32 has multiple adjustment holes 321 extending through it. Specifically, the left connector 31 and the right connector 32 are made of non-elastic metals, such as titanium alloy, stainless steel, chromium, etc., to prevent the left connector 31 or the right connector 32 from easily deforming during user use, affecting the position of the displayed image, and thus affecting the user comfort and display effect of the head-mounted display device.

[0042] Furthermore, the nose pads include a left nose pad 41 and a right nose pad 42. The left nose pad 41 is correspondingly disposed with the left connector 31, and the right nose pad 42 is correspondingly disposed with the right connector 32. The left nose pad 41 can be fixed to any adjustment hole 321 on the left connector 31, and the right nose pad 42 can be fixed to any adjustment hole 321 on the right connector 32 to adjust the distance between the left nose pad 41 and the right nose pad 42, thereby adjusting the height of the display screen on the user's viewing side relative to the user's eyes.

[0043] Specifically, the display screen formed by the micro-display panel and optical module has an optimal viewing angle. For example, if the user has a high or narrow nose bridge, the distance between the left nose pad 41 and the right nose pad 42 can be adjusted to decrease, allowing the left and right nose pads 41 and 42 to rest against the narrower part of the user's nose bridge, thus raising the contact position and adapting the user's eye height to the optimal viewing angle. If the user has a low or wide nose bridge, the distance between the left and right nose pads 41 and 42 can be adjusted to increase, allowing the left and right nose pads 41 and 42 to rest against the wider part of the nose bridge, thus lowering the contact position and adapting the user's eye height to the optimal viewing angle. Thus, by adjusting the height of the display screen relative to the user's eyes according to different users, the comfort of the head-mounted display device for different groups of people is increased, and the image display effect of the head-mounted display device is improved.

[0044] See Figure 4 The image shows a comparison between users with high / narrow nose bridges and users with low / wide nose bridges. When users with high / narrow nose bridges wear the head-mounted display device, the distance between the left nose pad 41 and the right nose pad 42 needs to be adjusted to be closer together. Conversely, when users with low / wide nose bridges wear the head-mounted display device, the distance between the left nose pad 41 and the right nose pad 42 needs to be adjusted to be wider together. It should be noted that the terms "high nose bridge" and "low nose bridge" mentioned in this embodiment are general terms; the specific adjustment scheme needs to be adjusted according to the actual situation of wearing the head-mounted display device.

[0045] Further, refer to Figure 1The left connector 31 and the right connector 32 each include a first end and a second end, and a plurality of adjustment holes 321 are arranged in the direction from the first end to the second end. In the left connector 31, its first end is connected to the left lens box 101, and its second end extends in a direction away from the left lens box 101. In the right connector 32, its first end is connected to the right lens box 102, and its second end extends in a direction away from the right lens box 102. Specifically, the first ends of the left connector 31 and the right connector 32 can be symmetrically fixed to the lower part of the lens body 10 near the connecting rod 12. The distance between the left connector 31 and the right connector 32 gradually increases in the direction from their respective first ends to their respective second ends, and the plurality of adjustment holes 321 on the left connector 31 and the plurality of adjustment holes 321 on the right connector 32 are symmetrically arranged.

[0046] Specifically, the left connector 31 and the right connector 32 each include a first connecting portion 301 and a second connecting portion 302. The first connecting portion 301 and the second connecting portion 302 can be integrally formed, mechanically connected, or bonded. The first end is located at the end of the first connecting portion 301, and the second end is located at the end of the second connecting portion 302. An adjustment hole 321 is provided in the second connecting portion 302. During the adjustment of the position of the left nose pad 41 or the right nose pad 42, the space around the first connecting portion 301 can provide movement space for the left nose pad 41 and the right nose pad 42, avoiding positional interference with the lens body 10 that could lead to adjustment failure.

[0047] Specifically, to facilitate alignment with the bridge of the nose, the second connecting portions 302 of the left connector 31 and the right connector 32 are respectively set to be parallel to the direction of the user's nasal wings; the first connecting portion 301 is set as a rectangular metal strip, and the end of the first connecting portion 301, i.e. the first end, is perpendicularly connected to the corresponding lens case (left lens case 101 or right lens case 102). The first connecting portion 301 is gradually twisted from its end so that it is located on the same plane as the second connecting portion 302, forming a smooth arc strip.

[0048] In this embodiment, two adjustment holes 321 are provided, including a first position adjustment hole 3211 and a second position adjustment hole 3212. The first position adjustment hole 3211 is close to the first end of the left connector 31 / right connector 32, and the second position adjustment hole 3212 is close to the second end of the left connector 31 / right connector 32. The distance between the two first position adjustment holes 3211 on the left connector 31 and the right connector 32 is relatively small, and the distance between the two second position adjustment holes 3212 is relatively large. For example, refer to... Figure 1 and Figure 2 When the user's nose bridge is high / thin, using the first wearing position of the head-mounted display device, the left nose pad 41 and right nose pad 42 are moved to the first position adjustment holes 3211 of the left connector 31 and right connector 32 respectively, to reduce the distance between the left nose pad 41 and right nose pad 42; Reference Figure 1 and Figure 3 When the user's nose bridge is low / wide, the second wearing position of the head-mounted display device is used to move the left nose pad 41 and right nose pad 42 to the second position adjustment hole 3212 respectively, thereby increasing the distance between the left nose pad 41 and right nose pad 42. In other embodiments, more than two adjustment holes 321 may be provided, which is not limited here.

[0049] Furthermore, a connecting portion 3213 is provided between two adjacent adjustment holes 321, and the inner diameter of the connecting portion 3213 is smaller than the inner diameter of the adjustment hole 321. Specifically, the connecting portion 3213 between the two adjustment holes 321 consists of two concave arc-shaped segments, and the width between the two arc-shaped segments is smaller than the width between the two side walls of the adjustment hole 321. The connecting portion 3213 restricts the relative position of the left nose pad 41 or the right nose pad 42 to the first position adjustment hole 3211 and the second position adjustment hole 3212, ensuring that the left nose pad 41 or the right nose pad 42 will not slide arbitrarily and change its relative position with the first position adjustment hole 3211 and the second position adjustment hole 3212, thereby increasing the reliability of the movement position of the left nose pad 41 or the right nose pad 42.

[0050] Furthermore, the left nose pad 41 and the right nose pad 42 each include an abutment portion 401 and a locking portion 402. The abutment portion 401 abuts against the user's nasal wing, and the locking portion 402 is connected to the abutment portion 401 and can be locked onto the inner wall of the adjustment hole 321. In this embodiment, the left nose pad 41 and the right nose pad 42 each also include a limiting portion 403. The limiting portion 403 is disposed on the side of the locking portion 402 opposite to the abutment portion 401, and the outer diameter of the limiting portion 403 is larger than the inner diameter of the adjustment hole 321. The limiting portion 403 can prevent the left nose pad 41 from detaching from the left connector 31 or the right nose pad 42 from detaching from the right connector 32. The abutment portion 401, the locking portion 402, and the limiting portion 403 are integrally formed. Optionally, the left nose pad 41 and right nose pad 42 are capable of elastic deformation. The contact portion 401 is made of an elastic material to increase user comfort; the snap-fit ​​portion 402 is made of an elastic material to facilitate movement through the connecting portion 3213, between the first position adjustment hole 3211 and the second position adjustment hole 3212 after elastic deformation; the limiting portion 403 is made of an elastic material to facilitate passing through the adjustment hole 321 after deformation, thereby limiting and fixing the left nose pad 41 or right nose pad 42 to the adjustment hole 321. Specifically, the left nose pad 41 and right nose pad 42 are made of silicone or rubber.

[0051] In other embodiments, the limiting part 403 may be omitted, and the abutting part 401 and the snap-fit ​​part 402 may be integrally formed. The snap-fit ​​part 402 may be able to undergo elastic deformation, and by snapping the snap-fit ​​part 402 against the side wall of the adjustment hole 321, the left nose pad 41 or the right nose pad 42 may be fixed to the corresponding adjustment hole 321. In other embodiments, an annular groove may be provided around the snap-fit ​​part 402, and the side wall of the adjustment hole 321 may be embedded in the groove, thereby fixing the left nose pad 41 or the right nose pad 42 to the corresponding adjustment hole 321.

[0052] Furthermore, the adjustment hole 321 is configured as a square hole, and the cross-section of the latching part 402 is square. By configuring the latching part 402 as a square rod, rotation of the latching part 402 within the adjustment hole 321 is prevented, improving the convenience of wearing the head-mounted display device. In other embodiments, the cross-section of the latching part 402 can be configured as elliptical or polygonal, and the shape of the adjustment hole 321 corresponds to the cross-sectional shape of the latching part 402.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
