[0003] [Technical Field]

[0004] This invention relates to the field of smart wearable device technology, and more particularly to a near-eye display device.

[0005] [Background Technology]

[0006] Smart wearable devices can achieve functions such as health monitoring, motion tracking, information reminders, voice assistants, navigation, and playback control. With the development of technologies such as AR (Augmented Reality), VR (Virtual Reality), and MR (Mixed Reality), wearable devices such as head-mounted displays can bring users a more immersive digital experience.

[0007] Related technologies often involve the connection structure between the frame and the temples. During the rotation of the temples relative to the frame, the internal electrical wires are often exposed relative to the connection structure. Over a long period of time, such as when the user rotates the temples to put them on or take them off, the internal electrical wires are easily damaged.

[0008] [Summary of the Invention]

[0009] This application provides a near-eye display device to solve the problems of exposed wires at the junction of existing near-eye display devices, which are easily damaged.

[0010] To solve the above-mentioned technical problems, one technical solution adopted in this application is: to provide a near-eye display device, comprising:

[0011] The frame includes a first cavity; a near-eye display module is disposed within the frame; a first limiting part is connected to the frame and has a first through hole, which communicates with the first cavity; a first temple has a second cavity; a first electrical device is disposed within the second cavity; a second limiting part is connected to the first temple and has a second through hole, which is rotatably connected to the first limiting part; the second through hole and the second cavity communicate with each other, and the first through hole and the first cavity are interconnected; a first wire passes through the first through hole and the second through hole and is electrically connected to the near-eye display module and the first electrical device; a second temple has a third cavity and is rotatably connected to the frame; a second electrical device is disposed within the third cavity; and a second wire extends laterally along the frame, passing through the first through hole and the second through hole and being electrically connected to the second electrical device and the first electrical device.

[0012] The beneficial effects of this application are as follows: The near-eye display device provided in this application has the near-eye display module set in the frame, the first electrical device set in the first temple, and the second electrical device set in the second temple. This can effectively balance the weight of the entire device without the need for additional counterweights. In addition, the first wire electrically connects the near-eye display module and the first electrical device, and the second wire extends laterally and electrically connects the near-eye display module and the second electrical device. Both the first and second wires pass through the first and second through holes, which can effectively reduce the exposure of the two wires and effectively reduce the wear on the wires during use. The second electrical device is set separately in the second temple 260, and the second electrical device and the first electrical device are electrically connected by the laterally extending second wire. This can make full use of the space in the temple, allowing for the placement of a larger capacity battery and effectively improving the overall battery life.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] Referring to Figures 1-17, this application proposes a near-eye display module 100a, applied to a frame 10. The frame 10 can be part of eyeglasses, a near-eye display device 200a, a helmet, or a similar head-mounted device. The frame 10 and the near-eye display module 100a can be assembled as a whole or as two independent components onto the aforementioned devices or equipment. The frame 10 and the near-eye display module 100a can be movably connected. The first housing 20 can be fixed to the frame 10 in a detachable or releasable manner. The near-eye display module 100a includes a first housing 20, a microdisplay assembly 30, a first sliding part 50, and a damping rotation mechanism 60. The first housing 20 can be made of plastic or metal and has a first receiving cavity 21. The microdisplay assembly 30 is disposed in the first receiving cavity 21 and is used to generate light. An optical element 40 is disposed in the first housing 20 and located on the light-emitting side of the microdisplay assembly 30. The optical element 40 can be made of materials such as PMMA (polymethyl methacrylate), PC (polycarbonate) plastic, glass, or resin. Light from the microdisplay assembly 30 enters through the first end of the optical element 40 and exits through the second end, which are opposite ends of the optical element 40, as illustrated in Figures 1-3. The light from the microdisplay assembly 30 can exit along the optical axis O of the optical element 40. The light from the microdisplay assembly 30 can undergo multiple reflections within the optical element 40 before exiting. In other embodiments, the light from the microdisplay assembly 30 can undergo refraction and reflection within the optical element 40 before exiting. Once the light from the optical element 40 exits, digital content can be displayed to the human eye.

[0053] The first sliding portion 50 is located on one side of the first housing 20 and is configured to connect with the second sliding portion 12 of the frame 10. The first sliding portion 50 can be located beside or on the bottom of the first housing 20. The location of the first sliding portion 50 on one side of the first housing 20 can be understood as the positional relationship of the first sliding portion 50 relative to the first housing 20. The connection relationship can be that the first sliding portion 50 is directly connected to the first housing 20 or indirectly connected to the first housing 20. One of the first sliding portion 50 and the second sliding portion 12 may include a protrusion, and the other may include a groove. The two cooperate to allow the first sliding portion 50 and the second sliding portion 12 to slide or move relative to each other. In some embodiments, the first sliding portion 50 and the second sliding portion 12 may include a length extending in a predetermined direction. In some embodiments, the first sliding portion 50 and the second sliding portion 12 may also include, for example, rolling between cooperating balls or rolling between meshing gears.

[0054] The damping rotation mechanism 60 is located between the first housing 20 and the first sliding part 50. The damping rotation mechanism 60 is rotatably connected to the first housing 20. The first housing 20 is configured to allow damped rotation relative to the frame 10 via the damping rotation mechanism 60 and to maintain the optical element 40 at a predetermined fixed angle relative to the frame 10 for light emission. Taking the frame 10 on the near-eye display device 200a as an example, the predetermined fixed angle of light emission can be the vertical direction of the near-eye display device 200a corresponding to the user's eyes. It can be understood that the damping rotation mechanism 60 can be tightly connected to the first housing 20 and allows mutual rotation. For example, mutual rotation can be achieved by external force, such as the user's hand or a tool, to rotate the first housing 20 relative to the damping rotation mechanism 60. The damping rotation mechanism 60 and the first housing 20 are tightly fitted with a pre-tightening force. When the first housing 20 rotates relative to the frame 10 to the angle expected by the user, the microdisplay assembly 30 and the optical element 40 are located on the first housing 20 and rotate synchronously. At the same time, the microdisplay assembly 30 and the optical element 40 follow the first housing 20 and remain fixed at the expected rotation angle, thereby enabling the optical element 40 to emit light at the angle expected by the user, achieving the adjustment of the light emission angle that meets the user's expectations.

[0055] The first sliding part 50 is configured to allow movement relative to the second sliding part 12, and to drive the damping rotation mechanism 60 and the first housing 20 to move synchronously relative to the frame 10, thereby maintaining the optical element 40 in a predetermined fixed lateral position relative to the frame 10. This lateral position can be the extension direction of either the first sliding part 50 or the second sliding part 12. For example, the lateral position of the frame 10 on the near-eye display device 200a can be the direction corresponding to the left or right eyes of the user wearing the device. It is understandable that mutual movement or sliding can be achieved through external force. For example, the user's hand or a tool can be used to move the first housing 20 laterally. The first sliding part 50 moves relative to the second sliding part 12 of the frame 10, which drives the damping rotation mechanism 60 connected to the first housing 20 to move synchronously relative to the frame 10. At this time, the microdisplay assembly 30 and the optical element 40 are located on the first housing 20 and move synchronously. The first sliding part 50 and the second sliding part 12 can maintain a tight fit. At the same time, the microdisplay assembly 30 and the optical element 40 follow the first housing 20 and remain fixed in the expected lateral position. The lateral position can be the rotation center A of the rotating shaft of the damping rotation mechanism 60, or the extension direction of the first sliding part 50. This enables the optical element 40 to emit light at the lateral position expected by the user, achieving the lateral light emission position adjustment that meets the user's expectations.

[0056] The above method enables the near-eye display module 100a to be assembled into the frame 10 of the near-eye display device 200a, or to be worn by a person, so that the horizontal field of view of the optical element 40 can be adjusted through the first sliding part and the second sliding part, and the vertical field of view of the optical element 40 can be adjusted through the damping rotation mechanism 60. This allows different users to have clear viewing within their respective fields of vision. At the same time, the movement of the first sliding part 50 drives the damping rotation mechanism 60, the first housing 20, the microdisplay assembly 30 and the optical element 40 to move synchronously relative to the frame 10, which effectively improves the stability of the overall components during movement. It also ensures that the damping rotation mechanism 60 can rotate at various lateral positions during movement, effectively improving the accuracy of the field of view adjustment.

[0057] In some embodiments, referring to Figures 1 and 4, the rotation center A of the damping rotation mechanism 60 is parallel to the plane containing the microdisplay assembly 30. This means that the entire microdisplay assembly 30 or its main body can be flat; for example, the microdisplay 31 of the microdisplay assembly 30 can be flat or plate-shaped, and its own plane or the plane it is located on can be used as a reference. The direction of the rotation center A can also be described as transverse in some embodiments. The parallelism between the rotation center A of the damping rotation mechanism 60 and the plane containing the microdisplay assembly 30 ensures that the entire microdisplay assembly 30 or its main body (i.e., the microdisplay 31) remains relatively fixed during rotation, reducing the risk of positional deviation of the microdisplay assembly 30 during rotation. The first sliding portion 50 is located on the side of the first housing 20 away from the optical element 40, effectively reducing the width impact caused by the first sliding portion 50 being located beside the first housing 20. Therefore, when the near-eye display module 100a is assembled into the frame 10, for example, into the frame 10 of the near-eye display device 200a, the width of the frame 10 can be effectively reduced, which is beneficial for the concealed design of the near-eye display module 100a. The first sliding portion 50 extends along the rotation center A of the rotation axis of the damping rotation mechanism 60. The extension length of the first sliding portion 50 is less than the length of the microdisplay assembly 30, effectively reducing the material and weight of the first sliding portion 50, further effectively reducing the weight of the near-eye display module 100a, which is beneficial for the lightweight design of the near-eye display module 100a after assembly into the frame 10.

[0058] In some embodiments, referring to Figures 1-4, the first housing 20 is provided with a first hole 22, and the damping rotation mechanism 60 includes a locking member 61 and a bushing 62. The central axis connecting the locking member 61 and the first hole 22 is the direction of the rotation center A. The rotation shaft of the damping rotation mechanism 60 can be located on the locking member 61. The locking member 61 passes through the bushing 62 and is fixed to the first hole 22. The locking member 61 can be a screw, bolt, or bolt. The locking member 61 can be provided with external threads, and the inner wall of the first hole 22 can be provided with internal threads. The two are threadedly connected to each other. In other embodiments, the locking member 61 and the first hole 22 can also be connected by an interference fit. For example, the shaft of the locking member 61 is inserted into the first hole 22 to produce elastic deformation to achieve a damping connection. In other embodiments, the locking member 61 can be a pin structure inserted into the first hole 22, and damping materials such as rubber rings or damping coatings are provided on its mating surface to achieve damping rotation. In other embodiments, the locking member 61 and the first hole 22 are connected by a key or glue to achieve damping rotation. The first sliding part 50 is connected to the outer periphery of the bushing 62. The first sliding part 50 extends away from the locking member 61. It can be understood that by connecting the first sliding part 50 and the locking member 61 together, the first sliding part 50 can drive the entire damping rotation mechanism 60 to move along the direction (or laterally) of the rotation center A. At the same time, when the first sliding part 50 and the second sliding part 12 are connected, the first sliding part 50 is circumferentially fixed and supported, thereby allowing the first housing 20 to rotate relative to the frame 10 through the damping rotation mechanism 60. For example, the user can operate the first housing 20 by hand or external clamps to achieve the rotation of the first housing 20, thereby driving the synchronous rotation of the optical element 40 to achieve the desired fixed angle light output adjustment.

[0059] In some embodiments, referring further to Figures 1-4, the damping rotation mechanism 60 may also include a first washer 63 and a second washer 64. The locking member 61 passes through the bushing 62, the first washer 63 and the second washer 64 and is fixed in the first hole 22. The first washer 63 and the second washer 64 may be made of rubber, plastic, metal or composite materials, etc. The two washer can ensure that the locking member 61 and the first hole 22 are more firmly fixed, effectively improving the damping effect during rotation, reducing the possibility that the damping rotation mechanism 60 is too loose during rotation and causing the first housing 20 to fail to maintain the expected fixed rotation position. That is, when the user rotates the first housing 20 to the expected angle, the first housing 20 can still maintain the position at the angle by relying on this damping force, ultimately ensuring that the optical element 40 emits light at the expected stable angle.

[0060] In some embodiments, as shown in FIG4, the first washer 63 and the second washer 64 are respectively located on both sides of the shaft 62, that is, the bushing 62 is clamped by the first washer 63 and the second washer 64. The locking member 61 may have a threaded shaft part 611 and a head 612 such as a slotted or cross-shaped head. The first washer 63, the second washer 64 and the bushing 62 may be sleeved on the shaft part 611. The shaft part 611 is fixed into the first hole 22 by rotating the head 612. One washer may be located between the head 612 of the locking member 61 and the bushing 62, and the other washer may be located between the bushing 62 and the first housing 20.

[0061] In other embodiments, the first gasket 63 and the second gasket 64 are both located on the same side of the bushing 62. The first gasket 63, the second gasket 64 and the bushing 62 are sleeved on the shaft portion 611. The first gasket 63 and the second gasket 64 are both located between the head 612 and the bushing 62, or the first gasket 63 and the second gasket 64 are both located between the first housing 20 and the bushing 62.

[0062] In some embodiments, the first housing 20 may further be provided with a protrusion 24, which may protrude relative to the side of the first housing 20. The protrusion 24 may be cylindrical and has a threaded first hole 22. The bushing 62 is at least partially fitted onto the protrusion 24. It is understood that the protrusion 24 can effectively reduce the length of the shaft portion 611 of the locking member 61. The bushing 62 can be fitted onto the protrusion 24 and pressed and fixed in the first hole 22 by the head 612 of the locking member 61. In some embodiments, the bushing 62 may be partially fitted onto the protrusion 24 and partially fitted onto the shaft portion 611 and fixed in the first hole 22. In other embodiments, regarding the first gasket 63 and the second gasket 64, the first gasket 63, the second gasket 64, and the bushing 62 may all be fitted onto the protrusion 24, or a portion of the first gasket 63, the second gasket 64, and the bushing 62 may be fitted onto the protrusion 24 and another portion onto the shaft portion 611. The extension length of the first sliding portion 50 is less than the radial dimension of the optical element 40, thereby effectively reducing the length of the first sliding portion 50 and lowering the overall weight.

[0063] In some embodiments, referring to FIG4, the microdisplay assembly 30 includes a microdisplay 31, a third wire 32, and a first electrical interface 33 electrically connected to each other. The microdisplay 31 and the optical element 40 are aligned. The microdisplay 31 may include, but is not limited to, Micro-LED (Micro Light-Emitting Diode), Micro-oled (Micro Organic Light-Emitting Diode), LCoS (Liquid Crystal On Silicon), LCD (Liquid Crystal Display), DMD (Digital Micromirror Device) / DLP (Digital Light Processing) or LBS (Laser Beam Scanning), or any combination of these technologies. The third wire 32 connects the microdisplay 31 and the first electrical interface 33. The third wire 32 can be a flexible electrical plate. The damping rotation mechanism 60 and the first sliding part 50 are both located on the side of the first housing 20 closer to the microdisplay 31 and farther from the first electrical interface 33, avoiding positional interference between the first sliding part 50 and the first electrical interface 33 during movement and rotation. This facilitates the assembly of the near-eye display module 100a into the frame 10 and makes it convenient to rotate and move the near-eye display module 100a. Referring to Figures 4 and 7, the microdisplay 31 and the third wire 32 are electrically connected to the second electrical interface 2510 through the first electrical interface 33. The second electrical interface 2510 can be located inside the first cavity 101 of the frame 10. The second electrical interface 2510 can be further electrically connected to the first electrical device 230 (e.g., processor 2301) located on the first temple 220a through the first wire 250. In some embodiments, a reinforcing plate or a buffer core 34 may also be provided on the back of the first electrical interface 33.The microdisplay 31, the third wire 32, and the first electrical interface 33 are sealed to the first housing 20, as shown in Figure 4. The first housing 20 may also be provided with a cover plate 26, which is sealed to the first housing 20 to seal the microdisplay 31 and the third wire 32 within the first accommodating cavity 21. Alternatively, an opening may be provided on the cover plate 26 at the position corresponding to the first electrical interface 33 to allow the first electrical interface 33 and the second electrical interface 2510 to be electrically connected. In other embodiments, the cover plate 26 may not be provided. After the first electrical interface 33 and the second electrical interface 2510 are electrically connected, the microdisplay 31, the third wire 32, the first electrical interface 33, and the second electrical interface 2510 are sealed with glue by potting. By sealing the microdisplay 31, the third wire 32, and the first electrical interface 33 to the first housing 20, the waterproof effect of the near-eye display module 100a can be effectively improved, reducing the risk of sweat or rainwater seepage during wear. In some embodiments, the extension length of the first sliding portion 50 may be less than the length of the microdisplay 31, thereby reducing the size of the first sliding portion 50 and lowering the overall weight.

[0064] Referring to Figure 9, the bushing 62 may include an annular body 621a and a second hole 623 located in the annular body 621a, with the shaft portion 611 passing through the second hole 623. The first sliding portion 50 may include a connecting portion 52 and an outer edge portion 54, wherein the connecting portion 52 is connected to the outer periphery of the annular body 621a, for example, it may be tangent to the annular body 621a, and the outer edge portion 54 is connected to the connecting portion 52. The width of the outer edge portion 54 is greater than the width of the connecting portion 52 in the direction away from the annular body 621a. The second sliding portion 12 may include a groove adapted to the shape of the first sliding portion 50, and the connecting portion 52 and the outer edge portion 54 may be tightly fitted and engaged in the groove, thereby achieving position fixation during the sliding process.

[0065] In some embodiments, referring to Figures 2, 3, and 8, the near-eye display module 100a further includes a rotation center A passing through the rotation axis of the damping rotation mechanism 60 and passing through a first central surface S1 of the frame 10. For example, the frame 10 of the first housing 20 has a bottom plane, and the first central surface S1 is perpendicular to this plane. Alternatively, the first central surface S1 may be a symmetrical central surface of the frame 10. For example, the second sliding part 12 may include grooves on both sides, which are symmetrical with respect to the first central surface S1. The optical element 40 includes a second central surface S2, and the overall structure of the optical element 40 may be symmetrical with respect to the second central surface S2. In some embodiments, the second central surface S2 may also be the center of the first housing 20, or it may be a surface passing through the optical axis O. It is understood that the above-mentioned central surface is only for the convenience of describing the relative rotational relationship between the optical element 40 and the frame 10. In other embodiments, if other reference frames (such as reference planes or reference centers) are used to directly or indirectly describe the relative rotational relationship between the optical element 40 and the frame 10, they should still fall within the protection scope of the rotation angle of this application. The rotation angle C of the second center plane S2 relative to the first center plane S1 is 0-25°, such as 0°, 5°, 10°, 13°, 15°, 20°, 25°, etc. Of course, the actual rotation angle is not limited to the above values, and users can change it according to actual needs. Figure 2 is an example diagram of the first housing 20 driving the optical element 40 to rotate to the first position. The rotation angle C of the second center plane S2 relative to the first center plane S1 can be 0°. At this time, the two center planes coincide. When the frame 10 and the first housing 20 are both flat, the frame 10 and the first housing 20 are parallel to each other, or the optical element 40 is parallel to the frame 10. Figure 8 is an example diagram of the first housing 20 driving the optical element 40 to rotate to the second position. The rotation angle C of the second center plane S2 relative to the first center plane S1 is not 0°.

[0066] In some embodiments, referring to Figures 2-3, the moving distance of the first housing 20 relative to the frame 10 is 0-1cm, such as 0, 0.1cm, 0.2cm, 0.4cm, 0.5cm, 0.7cm, 0.8cm, 0.9cm, 1cm, etc. Of course, the actual moving distance is not limited to the above values, and users can change it according to actual needs. Since the microdisplay 31 and the optical element 40 are set on the first housing 20, the first housing 20 drives the microdisplay 31 and the optical element 40 to move synchronously, realizing lateral light emission at different positions. As shown in Figure 2, this position can be understood as the initial position, at which time the moving distance is 0cm. Figure 3 is an example diagram of the first housing 20 moving a distance greater than 0cm relative to the frame 10. Figure 3 also illustrates that the first housing 20 drives the optical element 40 of the frame 10 to rotate an angle greater than 0°. It is understood that the near-eye display module 100a of this application can be moved and rotated separately, and can also be rotated during movement or moved during rotation. In the lateral position, the damping rotation mechanism 60 can be moved as a whole, which effectively improves the flexibility and accuracy of the light output angle of the near-eye display module 100a, while effectively reducing interference and damage to the device during movement and operation.

[0067] In some embodiments, referring to FIG10, the optical element 40 further includes a light-incident surface 42, a first reflective surface 43, a second reflective surface 44, and a light-emitting surface 45; the light-incident surface 42 is located at a first end; the first reflective surface 43 is located at a second end opposite to the first end; the second reflective surface 44 is located at the first end and surrounds the light-incident surface 42. The light-emitting surface 45 is located at the second end and surrounds the first reflective surface 43. The microdisplay assembly 30 faces the light-incident surface 42, and the second optical element 60a faces the light-emitting surface 45. The optical element 40 may be a solid substrate structure made of transparent or light-transmitting material, with the light-incident surface 42 and the second reflective surface 44 located at the first end of the solid substrate, and the first reflective surface 43 and the light-emitting surface 45 located at the second end of the solid substrate. In some embodiments, the optical element 40 may be a hollow structure, for example, a hollow structure between the first end and the second end. It is understood that the first reflective surface 43 and the second reflective surface 44 are coated with a reflective film, such as a metal or metal alloy reflective film made of silver, aluminum, etc. The microdisplay 30 faces the light-inlet surface 42, and the second optical element 60a faces the light-outlet surface 45. The light generated by the microdisplay 31 enters through the light-inlet surface 42 and is projected onto the first reflecting surface 43, then reflected by the first reflecting surface 43 to the second reflecting surface 44, and finally emitted from the light-outlet surface 45. The first reflecting surface 43 and the second reflecting surface 44 may include one or a combination of inclined plane, arc surface, spherical surface, aspherical surface or freeform surface. The incident surface and the exit surface 46 may be one or a combination of plane, arc surface, spherical surface, aspherical surface or freeform surface.

[0068] In some embodiments, the first reflecting surface 43 and the light-emitting surface 45 can be continuous surfaces, and the light-entering surface 42 and the second reflecting surface 44 can be continuous surfaces. Continuous surfaces can be understood as being constructed by the same function, for example, both being freeform surfaces constructed using the same Zernike polynomial function. In some embodiments, the surfaces formed by the first reflecting surface 43 and the light-emitting surface 45, and the surfaces formed by the light-entering surface 42 and the second reflecting surface 44 are constructed by the same function and can be parallel to each other. In some embodiments, the surfaces formed by the first reflecting surface 43 and the light-emitting surface 45, and the surfaces formed by the light-entering surface 42 and the second reflecting surface 44 are all freeform surfaces.

[0069] In some embodiments, the light-incoming surface 42 and the first reflective surface 43 can both be circular, elliptical, or polygonal, etc., and the shapes of the second reflective surface 44 and the light-emitting surface 45 can be polygonal, circular, elliptical, or closed shapes formed by arcs and straight edges, etc. In some embodiments, the light-incoming surface 42 and the first reflective surface 43 are the same or similar. In some embodiments, the area of ​​the first reflective surface 43 is greater than or equal to that of the light-incoming surface 42, and the area of ​​the light-incoming surface 42 is greater than or equal to the area of ​​the region of the microdisplay 30 used to generate light, thereby ensuring that the light from the microdisplay 30 can completely enter and be fully reflected before being emitted by the light-emitting surface 45.

[0070] In some applications, the optical element 40 can be cylindrical, such as a cylinder or an elliptical cylinder. During product assembly, it is often difficult to distinguish the accurate orientation of the optical element 40, leading to assembly errors. Therefore, referring to Figure 10, this application provides a chamfer 421a on the outer periphery of the light-receiving surface 42. The chamfer 421a can be a right-sided shape, a rhombus, a triangle, or a polygon. It can be understood that H1 and H2 constitute the total lateral dimension of the optical element 40. The intersection of H3 and H4 is the center of the first reflecting surface 43, and the intersection of H3 and H5 is the center R2 of the second reflecting surface 44. The light-receiving surface 42 is eccentrically positioned relative to the second reflecting surface 44. The center of gravity R1 of the light-receiving surface 42 is eccentrically positioned at a preset distance relative to the center R2 of the second reflecting surface 44. This eccentricity distance can be 0.1mm, 0.15mm, 0.2mm, etc. The straight edge chamfer 421a and / or eccentric setting are beneficial for identifying the orientation and direction of the optical element 40, that is, identifying the orientation of the orthographic projection surface of the optical element 40, for example, identifying the first end or the second end of the optical element 40; or it can be identified that the optical element 40 is rotated, for example, the positioning or orientation detection and identification of the optical element 40 is performed by machine vision during the assembly process, which is beneficial for the positioning and installation of the optical module 330 relative to the microdisplay 31, making the overall assembly more accurate.

[0071] In some embodiments, the light-incoming surface 42, the first reflecting surface 43, the second reflecting surface 44, and the light-emitting surface 45 comprise freeform surfaces generated by the same continuous function, meaning they can share a mold or mask material, effectively reducing the manufacturing cost of the optical element 40. The outer contour of the projected area of ​​the optical element 40 relative to the microdisplay assembly 30 includes a circle or an ellipse. It is understood that in some embodiments, the light-incoming surface 42 and the first reflecting surface 43 may be elliptical; alternatively, the light-emitting surface 45 may also be elliptical, wherein the longer side of the ellipse corresponds to the lateral field of view of the human eye, and the shorter side corresponds to the vertical field of view of the human eye. Considering that the lateral field of view of the human eye is greater than the vertical field of view, an elliptical outer contour design is more likely to meet the viewing requirements of the human eye.

[0072] Other designs or constructions of the optical element 40 can be found in the descriptions of the relevant embodiments in prior Chinese applications numbered 2023111912240, 2024205421010, 2023115809662 or 2023115822046.

[0073] In some embodiments, referring to Figures 4 and 7, the near-eye display module 100a may further include a sleeve 46a, a flange 22a on the first housing 20, and an optical element 40 located within the sleeve 46a. The sleeve 46a is configured to allow movable connection to the flange 22a and adjustment of the distance between the optical element 40 and the microdisplay assembly 30. It is understood that the sleeve 46a may have an internal thread 462, and the flange 22a may have an external thread; the threaded connection between the two enables adjustment of the distance between the optical element 40 and the microdisplay 31. In other embodiments, the sleeve 46a is configured to be releasably connected to the flange 22a; releasability may be provided by one or more mechanisms of various kinds to secure the components to each other. For example, mechanisms such as locks, latches, snaps, sliders, channels, screws, buckles, threads, magnets, pins, interference (e.g., friction) fits, rolling mills, snap pins, fused materials, fabrics, knitted fabrics, braided fabrics, hook and loop fasteners, and / or combinations thereof may be included to couple sleeve 46a and / or secure the first housing 20 together. Sleeve 46a and the first housing 20 may remain secured to each other until an optional release mechanism is actuated, such as an active operation by a user, such as squeezing, pressing, rotating, fitting, snapping, or fastening. In some embodiments, the first housing 20 and sleeve 46a have a closed connection state, such as the examples in Figures 1 and 3. Different positions of the optical element 40 relative to the microdisplay 31 can display digital content with different resolutions, allowing for adjustment of the distance of the optical element 40 according to the visual impairment of different visually impaired individuals.

[0074] In some embodiments, as shown in Figure 7, a second optical element 60a may also be provided on the sleeve 46a. The second optical element can be fixed to the sleeve 46a by means of snap-fit, adhesive, or threaded connection. The second optical element is located on the light-emitting side of the optical element 40 and is configured to provide the desired vision correction. The correction of the second optical element can be spherical, aspherical, toroidal, cylindrical, monocular, multifocal, progressive, and / or adjustable, for example, for correction of specific eyes or visual impairments such as myopia, hyperopia, and color blindness. Various correction combinations of the second optical element can be provided with different lenses or lens elements. For example, each of any given lens or lens element can have a known type of correction parameter based on the design identifier. Corresponding identifiers, such as those based on product inventory, can be assigned for reference and to facilitate selection for different vision users. In some embodiments, the second optical element may include concave lenses, convex lenses, convex cylindrical lenses, or other lenses with different refractive powers. The second optical element can correct the vision of light projected from the optical element 40 so that a user with visual impairment can clearly see the image content from the microdisplay 30. In other embodiments, the first housing 20 and the sleeve 46a can be separately separated, wherein the second optical element 60a can be fixed to the sleeve 46a, thereby allowing the sleeve 46a containing different vision-correcting second optical elements to be replaced according to the user's different vision.

[0075] In some embodiments, the second optical element 60a can provide the desired optical effect or optical crosstalk. For example, the second optical element may include one or more attenuators, diffusers, filters, polarizers, prisms, beam splitters, diffraction gratings, mirrors, and / or windows. In some embodiments, for users without visual impairments, correction may not be required, and the second optical element may be a plano lens or a zero-power lens, providing only protection for the optical element 40 and reducing wear on the optical element 40.

[0076] The projection area of ​​the second optical element in the first direction is greater than or equal to the projection area of ​​the first optical element 40 in the first direction, ensuring that the light from the microdisplay 30 can be fully corrected. The sleeve 46a is configured to be releasably connected to the first housing 20, allowing different users to replace different second optical elements 60a according to their own vision needs, so that users with visual impairments can still see the full and clear digital content from the microdisplay 30.

[0077] In some embodiments, the projected area of ​​the second optical element 60a in the first direction A can be 15 mm²-45 mm² (square millimeters), for example 15 mm². 2 17 mm 2 19 mm 2 20 mm2 36 mm 2 40 mm 2 45mm 2 The projected area of ​​the first optical element 40 in the first direction A is 10 mm. 2 -20mm 2 For example, 10 mm 2 12 mm 2 14 mm 2 17 mm 2 19 mm 2 20 mm 2 It is understandable that the projected area of ​​the second optical element needs to always be greater than or equal to the projected area of ​​the first optical element 40.

[0078] In some embodiments, the projected areas of the first housing 20 and the sleeve 46a in the first direction A are each no greater than 60 mm2. It is understood that, for example, the projected areas of the first housing 20 and the sleeve 46a can be 50 mm2, 54 mm2, 55 mm2, 60 mm2, etc. In some embodiments, such as those shown in Figures 1-3, the projected area of ​​the sleeve 46a in the first direction A is greater than the projected area of ​​the first housing 20. In other embodiments, such as those shown in Figures 6-9, the projected area of ​​the sleeve 46a in the first direction A is greater than the projected area of ​​the first optical element 40 but smaller than the projected area of ​​the first housing 20. The first housing 20 and sleeve 46a have a smaller projected area, thus having a smaller volume and weight, making it easier to integrate with the near-eye display device 200a. Compared with existing near-eye devices such as AR or VR, the module and device of this application are lighter in overall volume and weight, which is beneficial for users to wear for a long time. Moreover, it can be cleverly integrated with existing myopia glasses, farsighted glasses, sunglasses, protective glasses or smart glasses, without causing excessive weight and size, and is not too obtrusive in appearance, nor will it affect the user's normal field of vision.

[0079] The first housing 20, sleeve 46a, first optical element 40, and second optical element 60a can be circular, elliptical, or other various shapes. In some embodiments, the materials of the first housing 20 and sleeve 46a are at least partially different; for example, the hardness (rigidity) of the first housing 20 is greater than that of the sleeve 46a. The first housing 20 can be made of metal, plastic, etc., while the sleeve 46a can be made of an elastic or flexible material, such as silicone, rubber, or elastic plastic. The first housing 20 and sleeve 46a are configured to be elastically connected. In other embodiments, a portion of the first housing 20 may have a hardness greater than a portion of the sleeve 46a; this portion may be the part in contact with the first housing 20. The first housing 20 and the sleeve 46a can be elastically connected; in other embodiments, the first housing 20 and the sleeve 46a can also be elastically snapped together, that is, the sleeve 46a snaps onto the first housing 20, causing at least partial deformation or elastic deformation of the first housing 20 or the sleeve 46a; or when the two are threadedly connected, the first housing 20 or the sleeve 46a deforms or elastically. In other embodiments, for example, an elastic ring (or silicone ring, etc.) may be located in the gap of the snap-fit ​​or threaded connection, or the end of the sleeve 46a may abut against a flexible plate (or an elastic plate or a silicone plate). Therefore, different users can use different lenses or lenses as needed for the second optical element, and / or not use the second optical element 60a containing lenses or lenses.

[0080] In some embodiments, referring to Figures 5-17, this application also provides a near-eye display device 200a, which includes a frame 10, a first temple 220a, a second temple 260, and a near-eye display module 100a as described in the above embodiments. The near-eye display module 100a is disposed in the frame 10. The first temple 220a and the second temple 260 are rotatably connected relative to the frame 10, respectively. A first electrical device 230 and a second electrical device 232 are disposed in the first temple 220a and the second temple 260. The near-eye display module 100a is electrically connected to the first electrical device 230 and the second electrical device 232. The near-eye display device of this application can be a smart device such as smart glasses, AR (Augmented Reality), VR (Virtual Reality), or MR (Mixed Reality). The frame 10 has a first cavity 101, as shown in Figure 7. The near-eye display device 200a may also include a fixing block 16, which is fixed to the first cavity 101. The fixing block 16 has a second sliding part 12. It can be understood that the second sliding part 12 can be formed by directly cutting a groove in the frame 10, or by adding a fixing block 16 and setting the second sliding part 12 on the fixing block 16. Both can be understood as the second sliding part 12 being provided inside the frame 10. The near-eye display device 200a also includes a lens 105 disposed in the frame 10. The first housing 20 facing the human eye side 102 is also provided with scale markings. When the user operates the near-eye display module 100a to move relative to the frame 10, the user can clearly see the moving position, which can more accurately meet the user's adjustment needs.

[0081] Referring to Figures 1 and 7, the frame 10 may further include an upper frame 13 and a lower frame 14. A lens 105 can be installed between the upper frame 13 and the lower frame 14. The upper frame 13 can be located away from the lens 105. The rotation range of the first housing 20 toward the lens 105 is greater than its rotation range toward the upper frame 13. It can be understood that the first housing 20 is allowed to rotate at a greater angle toward the lens 105 or the lower frame 14 than it is toward the upper frame 13. Referring to the example in Figure 8, after the near-eye display module 100a is assembled into the frame 10, with reference to S1, the angle of rotation of the near-eye display module 100a toward the S2 direction (right side) is greater than the angle of rotation away from the S2 direction (left side). This facilitates efficient adjustment to a suitable vertical viewing angle for the user.

[0082] Referring to Figures 5-17, the near-eye display module 100a can be at least partially housed within the first cavity 101, with a portion protruding relative to the first cavity 101. The near-eye display module 100a can be configured to allow movement relative to the frame 10, such as sliding or rotating. In other embodiments, the near-eye display module 100a can also be fixed to the frame 10. The frame 10 may include a near-eye side (human eye side) 102 and a world side (environment side) 103 relative to the near-eye side 102. The near-eye display module 100a is used to generate light that is projected onto the near-eye side 102, and can project digital content onto the user's eye on the near-eye side 102. In some embodiments, the near-eye display module 100a can employ binocular parallax, integrated imaging, holographic technology, or retinal imaging technology, etc., to project digital content onto the human eye.

[0083] In some embodiments, the lens 105 can be detachably connected to the frame 10, allowing the user to change lenses for different vision corrections. Alternatively, the lens 105 can be fixedly connected to the frame 10 and not allowed to be detached by the user. The near-eye display module 100a can be a single unit, or two or more units. In some embodiments, the lens 105 can be a plano lens, sunglasses lens, or protective lens. In other embodiments, the lens 105 can be a vision-correcting lens, such as a lens for correcting specific eye conditions or visual impairments like myopia, hyperopia, or color blindness. The lens 105 can be spherical, aspherical, toroidal, cylindrical, single-vision, multifocal, progressive, and / or adjustable. In some embodiments, the projected area of ​​the near-eye display module 100a does not overlap with the lens 105 in the direction from the near-eye side 102 to the far-eye side 103, thereby reducing interference from the near-eye display module 100a with the normal visual field of the lens 105. In other embodiments, the projected area of ​​the near-eye display module 100a partially overlaps with that of the lens 105 in the direction from the near-eye side 102 to the far-eye side 103, or the near-eye display module 100a may be configured to move to the area of ​​the lens 105, that is, allow the near-eye display module 100a to be adjusted at a predetermined or arbitrary position of the lens 105.

[0084] The first limiting part 210a is connected to the frame 10. The first limiting part 210a can be connected to the frame 10 by means of adhesive, snap-fit, hinge, fastener fixation, etc. The materials of the first limiting part 210a and the frame 10 can be the same or different. The first limiting part 210a is provided with a first through hole 201, which communicates with the first cavity 101. The first temple 220a is provided with a second cavity 221. The first electrical device 230 is provided in the second cavity 221. The first electrical device 230 may include a circuit board. Referring to the system block diagram, the circuit board can be rigid or flexible. The circuit board can be a single piece or multiple pieces electrically connected to each other. The circuit board may include peripheral devices such as processor 2301, memory 2302, external capacitors / resistors / inductors and other peripheral devices 2308, operation units such as switches / control buttons and other operation units 2307, etc. In some embodiments, electrical devices such as microphone 2304 or vital signs / ambient light / brightness sensor 2306 may also be disposed in the second cavity 221.

[0085] The second limiting part 240 is connected to the first temple 220a. The second limiting part 240 can be connected to the first temple 220a by means of bonding, snap-fitting, hinge, fastener fixing, etc. The second limiting part 240 is provided with a second through hole 241, which can be understood as a groove, recess, through groove, or mounting groove, allowing components to be placed or passed through it. The second limiting part 240 and the first limiting part 210a are rotatably connected. The second limiting part 240 and the first limiting part 210a can be connected by hinge, rotary joint, spring hinge, etc., that is, the first temple 220a is rotatably connected to the frame 10 through the second limiting part 240 and the first limiting part 210a. The second through hole 241 and the second cavity 221 are connected, and the first through hole 201 and the first cavity 101 are connected. The first conductor 250 passes through the first through hole 201 and the second through hole 241 and is electrically connected to the near-eye display module 100a and the first electrical device 230.

[0086] The second temple 260 has a third cavity 261, and the second temple 260 is rotatably connected to the frame 10. The first temple 220a can be rotatably connected to the frame 10; in other embodiments, the first temple 220a can also be fixedly connected to the frame 10. A second electrical device 232 is disposed in the third cavity 261. The second electrical device 232 can be a power module, such as a rechargeable or replaceable battery via a charging interface 2322. A second wire 252 extends laterally along the frame 10. Lateral extension can be understood as crossing the direction of the left and right lenses 105, that is, the direction of the left and right glasses corresponding to the human eye after the near-eye display device 200a is worn. The second wire 252 passes through the first through hole 201 and the second through hole 241 and is electrically connected to the second electrical device 232 and the first electrical device 230. The first conductor 250 and the second conductor 252 can be flexible electrical conductors, which can be bent, folded, or bent. In another embodiment, the first conductor 250 can be a flexible conductor, and the second conductor 252 can be a non-flexible conductor. Electrical conductive lines can be printed on the first conductor 250 and the second conductor 252. The first conductor 250 and the second conductor 252 can be long and flat, or in some embodiments, they can be long cylindrical, or they can be multiple small long cylindrical strips arranged side by side. The overlapping portions of the projections of the first conductor 250 and the second conductor 252 on the frame 10 can be insulated from each other. The interior of the first conductor 250 and the second conductor 252 can be printed with metal (e.g., copper) conductive lines, and the surfaces of the two conductors can be coated with insulating material, so that contact between them will not cause an electrical short circuit. The frame 10 and the temple shell can be made of plastic, while the first limiting part 210a and the second limiting part 240 can be made of metal.

[0087] Related technologies often involve the connection structure between the frame and temples. During the rotation of the temples relative to the frame, the internal electrical wires are often exposed relative to the connection structure. Over time, this can easily damage the internal electrical wires during the user's rotation, wearing, and removal of the glasses. By placing the near-eye display module 100a in the frame 10, the first electrical device 230 in the first temple 220a, and the second electrical device 232 in the second temple 260, the weight of the entire near-eye display device 200a can be effectively balanced, eliminating the need for additional counterweights. Furthermore, the first wire 250 electrically connects the near-eye display module 100a and the first electrical device 230, and the second wire 252 extends laterally and electrically connects the near-eye display module 100a and the second electrical device 232. Both the first wire 250 and the second wire 252 pass through the first... The through-hole 201 and the second through-hole 241 can effectively reduce the exposure of the two wires and reduce the wear on the wires during use. The battery and other components are set separately as the second electrical device 232 in the second temple 260. The second electrical device 232 and the first electrical device 230 are electrically connected by the laterally extended second wire 252. The space of each temple can be fully utilized. For example, the second temple 260 can accommodate a larger capacity battery and is electrically connected to the near-eye display module 100a through the extended second wire 252, which effectively improves the battery life of the device.

[0088] In some embodiments, referring to Figures 11-14, the length of the first guide wire 250 is less than the length of the second guide wire 252. The near-eye display module 100a is configured to allow movement on the frame 10. A user can move the near-eye display module 100a by touching it with their finger or a tool. The first guide wire 250 moves at least partially within the first cavity 101 as the near-eye display module 100a moves relative to the frame 10. The movement of the first guide wire 250 can be understood as the first guide wire 250 being bent, folded, stretched, or unfolded. In some embodiments, the near-eye display module 100a is configured to bend the first guide wire 250 by moving towards the first temple 220a, and the near-eye display module 100a is also configured to unfold the first guide wire 250 by moving away from the first temple 220a. When the user slides the near-eye display module 100a towards the first temple 220a, the first wire 250 can be bent or folded, causing it to be retracted or rolled up and located in the first cavity 101. When the user slides the near-eye display module 100a away from the first temple 220a and towards the second temple 260, the first wire 250 is stretched, unfolded, or tends to be stretched and located in the first cavity 101. The second wire 252 is located in the frame 10 and remains fixed. The second wire 252 can be fixed in the frame 10 by means of potting, bonding, snap-fitting, or fastener connection. During the movement of the near-eye display module 100a, only a portion of the first wire 250 is rolled up or stretched, while the second wire 252 is not affected, effectively ensuring the stability of their respective electrical connections. The overlapping portions of the first wire 250 and the second wire 252 in the extension direction are electrically insulated. It is understood that, at the locations of the first cavity 101, the first through hole 201, and the second through hole 241, viewed from the projection direction from the near-eye side 102 to the environmental side 103, the first conductor 250 and the second conductor 252 at least partially overlap each other. For example, both the first conductor 250 and the second conductor 252 are made of flat flexible circuit boards. The first conductor 250 and the second conductor 252 can be made of polyester, polyethylene naphthalate, polyimide, or liquid crystal polymer, etc. In some embodiments, the first conductor 250 and the second conductor 252 have a metal conductive layer printed inside them. The surfaces of the two conductors can also be coated with insulating materials respectively. The surfaces of the first conductor 250 and the second conductor 252 are electrically insulated from each other, and they will not conduct electricity when in direct contact. This helps to ensure the independence of their respective electrical circuits and reduce the risk of short circuits.

[0089] In some embodiments, referring to Figures 11-17, the first conductor 250 may have a first snap-fit ​​hole 2501, and the second conductor 252 may have a second snap-fit ​​hole 2521. The first snap-fit ​​hole 2501 and the second snap-fit ​​hole 2521 may be the same size and shape, and the electrically conductive layers on the first conductor 250 and the second conductor 252 may respectively avoid the first snap-fit ​​hole 2501 and the second snap-fit ​​hole 2521. Since the second conductor 252 extends laterally along the frame 10, the second snap-fit ​​hole 2521 may include at least two and be spaced apart from each other, for example, there may be two or three second snap-fit ​​holes 2521 along the lateral direction of the frame 10. The frame 10 is provided with at least two snap-fit ​​posts 112, and the first snap-fit ​​hole 2501 and the second snap-fit ​​hole 2521 are respectively connected to the snap-fit ​​posts 112. For ease of understanding, only the snap-fit ​​post 112 located in the first cavity 101 is shown as an example. In reality, similar snap-fit ​​posts 112 can also be provided laterally on the frame 10 (not shown in the figure). For example, the second snap-fit ​​hole 2521 can be located in the middle of the frame 10 or near the bridge of the nose when the nose pad is worn, with the position of the snap-fit ​​post 112 corresponding to the second snap-fit ​​hole 2521. It can be understood that the snap-fit ​​post 112 can also be formed by the glue passing through the snap-fit ​​hole 2521 during the potting process and then curing. In some embodiments, the snap-fit ​​post 112 can be shared; for example, the snap-fit ​​post 112 can also be connected to the sealing plate 115. The first wire 250 and the second wire 252 are fixed to the locking post 112 through the first locking hole 2501 and the second locking hole 2521 respectively, thereby fixing the first wire 250 and the second wire 252, which facilitates the efficient assembly of the near eye display device 200a. In addition, when the near eye display module 100a moves relative to the frame 10, the first wire 250 is fixed by the locking post 112 located between the first temple 220a and the near eye display module 100a. Therefore, the first wire 250 is allowed to move between the first sliding part 50 and the locking post 112, effectively reducing excessive movement of the first wire 250 and reducing the risk of damage to the first wire 250.

[0090] In existing technologies, the temple-to-frame rotation structure often has a large opening at the hinge, especially from the time the temple is extended to when it is retracted. The larger the angle range from large to small, the larger the opening at the hinge needs to be. Therefore, the rotation process easily exposes the wires. Furthermore, the pivot of such hinge structures does not rotate; during rotation, the wires are forcibly bent at the opening, which can easily damage the wires over long-term use. In some embodiments, referring to Figures 11-16, the near-eye display device 200a may also include a rotating shaft 270, which is rotatably connected to the second limiting part 240 and / or the first limiting part 210a. That is, the rotating shaft 270 can rotate relative to the second limiting part 240, the first limiting part 210a, or simultaneously relative to both the first limiting part 210a and the second limiting part 240. The rotating shaft 270 is provided with a third through hole 271. The first through hole 201, the second through hole 241, and the third through hole 271 of this application can also be understood as a groove, through slot, or recess structure, which can be understood as a component being located in or passing through them. The first cavity 101, the first through hole 201, the third through hole 271, and the second cavity 221 are connected. The first wire 250 and the second wire 252 pass through the third through hole 271. The rotating shaft 270 is configured to drive the first wire 250 and the second wire 252 to rotate synchronously. The rotating shaft 270 can be mounted on the second limiting part 240 and located in the second through hole 241. The rotation of the pivot 270 allows the first wire 250 and the second wire 252 to rotate together as a whole. That is, the first wire 250 and the second wire 252 will rotate synchronously with the rotation of the pivot 270. For example, when the first temple 220a rotates relative to the frame 10, it can drive the pivot 270 to rotate relative to it. At this time, the first wire 250 and the second wire 252 are allowed to rotate synchronously, rather than simply bending. When the first temple 220a rotates relative to the frame 10, the third through hole 271 can always be connected to the first temple 220a and is not easily exposed to the user. This can effectively prevent the first wire 250 and the second wire 252 from being exposed during rotation, reducing the risk of water or other foreign objects entering and damaging the wires. When the rotation angle is the same or greater (relative to the prior art), this application can reduce the opening size of the third through hole 271 during the rotation of the temple relative to the frame, saving materials, and at the same time reducing the wear of bending or twisting of the first wire 250 and the second wire 252, effectively improving the protection of the first wire 250 and the second wire 252 during the rotation process.

[0091] In some embodiments, referring to Figures 11-14, the near-eye display device 200a may further include a fastener 280, which may be a screw or bolt, etc. The first limiting portion 210a may include a first connecting section 212, which has a fourth through hole 213. The second limiting portion 240 includes a second connecting section 242, which has a fifth through hole 243. The rotating shaft 270 has a fixing hole 272. The fixing hole 272, the fourth through hole 213, and the fifth through hole 243 may be coaxially arranged. The first connecting section 212 and the second connecting section 242 may be arc-shaped or annular protrusions. The fastener 280 passes through the fourth through hole 213 and the fifth through hole 243 and is connected to the fixing hole 272. For example, a single fastener 280 may completely pass through the fourth through hole 213 and the fifth through hole 243 and be connected to the fixing hole 272. In some embodiments, the second connecting segment 242 may be located inside the first connecting segment 212, and the rotating shaft 270 may be located inside the second connecting segment 242; in other embodiments, the second connecting segment 242 may be located outside the first connecting segment 212, and the rotating shaft 270 may be located inside the first connecting segment 212.

[0092] In some embodiments, continuing to refer to FIG15, the first connecting segment 212 includes two oppositely arranged segments, the second connecting segment 242 includes two oppositely arranged segments, and the fastener 280 includes two oppositely arranged segments. The second connecting segment 242 is located between the two first connecting segments 212. The first connecting segments 212 and the second connecting segment 242 can be U-shaped or semi-I-shaped, respectively. The rotating shaft 270 is located between the two second connecting segments 242. Each fastener 280 connects each second connecting segment 242 and each first connecting segment 212. The first wire 250 and the second wire 252 are located between the two fasteners 280. The length of the fastener 280 does not pass through the third through hole 271. The first wire 250 and the second wire 252 are spaced apart from the fasteners 280. By setting two fasteners 280 to fix the first connecting segment 212 and the second connecting segment 242 respectively, the contact between the first wire 250 and the second wire 252 and the fastener 280 can be effectively reduced, thus reducing wear on the wires.

[0093] In some embodiments, referring to FIG16, the rotating shaft 270 may include a first rotating shaft segment 2701 and a second rotating shaft segment 2702. The first rotating shaft segment 2701 and the second rotating shaft segment 2702 may have the same structure. The first rotating shaft segment 2701 and the second rotating shaft segment 2702 respectively include an annular segment 273, an extension segment 274 and a fixing segment 275. The annular segment 273 is provided with a fixing hole 272. The extension segment 274 and the fixing segment 275 extend away from the annular segment 273 and are spaced apart circumferentially along the fixing hole 272. The extension section 274 is provided with a connecting hole 276. The size of the extension section 274 can be larger than that of the fixed section 275. The fixed section 275 can be a columnar protrusion structure. The fixed section 275 of the first rotating shaft section 2701 is connected to the connecting hole 276 of the extension section 274 of the second rotating shaft section 2702. The connecting hole 276 of the extension section 274 of the first rotating shaft section 2701 is connected to the fixed section 275 of the second rotating shaft section 2702. The fixed section 275 and the connecting hole 276 can be snap-fitted, plugged in, or glued, etc. It can be understood that the first rotating shaft section 2701 and the second rotating shaft section 2702 are spliced ​​from the same structure and can be directly formed by the same mold, which can effectively reduce the mold opening cost. The first rotating shaft section 2701 and the second rotating shaft section 2702 can be made of plastic or the like. The material of the rotating shaft 270 can be different from that of the first limiting part 210a and the second limiting part 240, which can effectively reduce material and processing costs. Of course, in other embodiments, the materials of the pivot 270, the first limiting part 210a and the second limiting part 240 can also be the same, which can improve the overall robustness.

[0094] In some embodiments, referring to Figures 11-15, the frame 10 is provided with two oppositely arranged connecting grooves 111. The first limiting part 210a also includes a first limiting body 214 and a first protrusion 215. The first protrusion 215 and the first connecting segment 212 are respectively located at both ends of the first limiting body 214. The first protrusion 215 extends toward the side away from the first connecting segment 212. The first protrusion 215 includes two spaced-apart parts. The two first protrusions 215 are respectively fixedly connected to the two connecting grooves 111, such as by snap-fitting, tight fitting or bonding. In some embodiments, the inner wall of the connecting groove 111 may also be provided with a corresponding guide groove (not shown in the figure), which is beneficial for the first protrusion 215 to be accurately snapped into the connecting groove 111. The two first protrusions 215 can be parallel to each other, and the two first connecting segments 212 can be parallel to each other. The first protrusions 215 and the first connecting segments 212 can be parallel to each other. The first through hole 201 penetrates the first limiting body 214. The first protrusions 215 and the first connecting segments 212 are located on both sides of the first through hole 201. The frame 10 may also include a transition groove 114, which can communicate with the first cavity 101. The first wire 250 and the second wire 252 can pass through the transition groove 114 from the first cavity 101, then enter the third through hole 271, and finally enter the second cavity 221 to be electrically connected to the first electrical device 230 therein. One of the two connecting grooves 111 is above the transition groove 114, and the other connecting groove 111 is below the transition groove 114. The above method allows the frame 10 and the first limiting part 210a to be made of different materials, and the first protrusion 215 can be stably connected to the connecting groove 111, which is conducive to the concealed installation of the first wire 250 and the second wire 252 without exposure.

[0095] In some embodiments, referring to Figures 11-15, the first protrusion 215 may include periodically arranged protrusions away from the first limiting body 214. These protrusions may be, for example, wavy, sinusoidal, or spaced-apart. Such periodically arranged protrusions facilitate the formation of a larger contact area, allowing adhesives to fully bond the first protrusion 215 to the connecting groove 111. The periodically arranged protrusions 215 also help guide the first protrusion 215 into the connecting groove 111. In some embodiments, the first protrusion 215 has at least one through-hole 216 for accommodating adhesives, allowing for more adhesive to be contained, resulting in a more secure and stable connection between the first protrusion 215 and the connecting groove 111. This contributes to a more stable connection between the first protrusion 215 and the connecting groove 111. Furthermore, the through-hole 216 effectively reduces the overall weight of the first limiting part 210a, further reducing the weight of the near-eye display device 200a. The through hole 216 also facilitates the elastic deformation of the first protrusion 215, making it easier for the first protrusion 215 and the connecting groove 111 to engage.

[0096] Referring to Figures 4-7, the microdisplay assembly 30 may include a microdisplay 31, a third wire 32, and a first electrical interface 33 that are electrically connected to each other. The microdisplay 31 and the optical element 40 are aligned. The third wire 32 connects the microdisplay 31 and the first electrical interface 33. The first wire 250 is provided with a second electrical interface 2510, which is electrically plugged into the first electrical interface 33. The near-eye display device 200a also includes a sealing plate 115, which is connected to the frame 10 and seals the first cavity 101. The frame 10 may be provided with a positioning post 113. The sealing plate 115 can be fixedly connected to the positioning post 113 first, and then the sealing plate 115 and the frame 10 are sealed with sealant, thereby effectively preventing the first wire 250 from being exposed.

[0097] Referring to Figures 11-16, the rotational connection structure between the second temple 260 and the frame 10 can be exactly the same as the rotational connection structure between the first temple 220a and the frame 10. That is, the first limiting part 210a, the second limiting part 240 and the rotating shaft 270 described in the above embodiments are also applicable to the second temple 260 and the frame 10, and will not be repeated here.

[0098] It is understood that the first electrical device 230 may include a main control circuit board, on which a processor 2301, a memory 2302, a transceiver 2303, and peripheral devices 2308 such as capacitors / resistors / inductors may be mounted. The first temple 220a may also contain a microphone 2304, a right speaker 2305, an inertial sensor 2306a, and an interactive operation unit 2307 such as a switch button / touch / physical switch. These related devices can be electrically connected to the first electrical device 230, and all or part of them can be located on the main control board of the first electrical device 230, or they can be spaced apart from the main control circuit board. The second electrical device 232 may include a rechargeable battery. The second temple may also contain a left speaker 2321, a charging interface 2322, and a brightness or vital signs sensor 2323, thereby effectively balancing the weight of the left and right temples without the need for additional counterweights, ensuring a lighter overall weight for the near-eye display device 200a. The microphone 2304 can collect ambient or wearer sound sources, and the number of microphones 2304 can be one or more. The charging port 2322 can support wired or wireless charging. The left speaker 2321 and right speaker 2305 can play sound. The brightness sensor 2306 can detect the ambient light and adaptively adjust the display brightness of the microdisplay 1101. The inertia sensor 2306a can detect the wearer's posture. The operation unit 2307 allows the wearer to directly perform operations to achieve interaction, such as powering on / off, page turning, volume adjustment, play / pause, quick wake-up, or quickly calling the local AI assistant, etc.

[0099] In some embodiments, referring to Figures 13, 17, 31-33, the operation unit 2307 may further include an interactive control component 2307a for receiving interactive operation signals input by the user and converting them into a first electrical signal. The interactive control component 2307a may be electrically connected to the circuit board and may be located on the first temple 220a away from the eye side 102. The interactive control component 2307a may be located near the frame side, and the surface of this area may also have a micro-recessed or frosted texture to assist the user in accurately locating the operation (e.g., sliding) area without observation. The near-eye display device 200a may further include a wear detection component 2307b, which may be electrically connected to the circuit board. The wear detection component 2307b is located on the first temple 220a and facing the eye side 102, for sensing the user's wearing status and generating a second electrical signal. The processor 2301 collects the second electrical signal of the inner wear detection component 2307b in real time. When the difference value reaches a preset threshold, the device is determined to be in a "worn" state; otherwise, it is in a "not worn" state. It can be understood that the first electrical signal (interactive control) and the second electrical signal (wear detection) are transmitted directly or indirectly to the processor 2301 through a signal transmission channel inside the temple (such as a flexible circuit board or bonding wire). The processor 2301 can monitor the second electrical signal. When the difference value of the second electrical signal exceeds the preset wear threshold, the processor outputs an internal logic state of "wear valid". In the "wear valid" state, the processor 2301 begins to analyze the first electrical signal from the external interactive control component. The processor 2301 can identify "forward sliding" or "backward sliding" based on the level fluctuation characteristics of the first electrical signal, such as the direction of charge center of gravity movement, and then internally convert it into system control commands, such as volume control or application control commands, etc.

[0100] In some embodiments, the interaction control component 2307a may be disposed on the inner wall of the outer side of the temple, while the wear detection component 2307b may be disposed on the inner wall of the inner side of the temple. Due to the limited space in the thickness direction of the temple body, the orthographic projection of the interaction control component 2307a on the inner side has at least a partial overlap with the wear detection component 2307b in space. An insulating layer with a specific dielectric constant (such as the support portion of the temple body or a dedicated shielding sheet) may be disposed between the interaction control component 2307a and the wear detection component 2307b, and the physical distance between them in the thickness direction is controlled between 1.2 mm and 2.5 mm.

[0101] In some embodiments, as shown in FIG31, the wear detection component 2307b may include a first conductive sheet 224 and a second conductive sheet 226 extending along the length direction of the first temple 220a. The two conductive sheets may be made of metal (such as stainless steel or gold-plated copper), and may be mutually insulated, both being within the range that the user can touch or perceive at close range when wearing the glasses. Optionally, the first conductive sheet 224 and the second conductive sheet 226 may be arranged parallel to each other along the length direction of the temple. Optionally, the extension length of the first conductive sheet 224 and the second conductive sheet 226 may each account for more than 1 / 3 of the total length of the temple. The first conductive sheet 224 and the second conductive sheet 226 may be injection-molded surfaces on the inner side of the temple, and may be manufactured by laser direct forming (LDS) or by bonding metal foil. The first conductive sheet 224 is used to sense skin contact (either directly or indirectly through the temple shell), and the second conductive sheet 226 may be positioned near the upper or lower edge of the temple to minimize direct skin contact. It is used to collect ambient noise levels as a reference.

[0102] Optionally, the exposed area or effective sensing area of ​​the first conductive sheet 224 is significantly larger than that of the second conductive sheet 226. The exposed area of ​​the first conductive sheet 224 can be approximately 3 to 5 times that of the second conductive sheet 226. The surface area of ​​the first conductive sheet 224 is larger or significantly larger than that of the second conductive sheet 226. This asymmetric design of "large detection position + small reference position" can fully utilize the differential measurement principle. When the user wears the glasses, the skin mainly contacts the first conductive sheet 224, and the processor chip can effectively eliminate common-mode interference caused by sweat, environmental humidity, or temperature drift by comparing the signal difference between the two sheets. In some embodiments, the first conductive sheet 224, the second conductive sheet 226, and the interactive control component 2307a are all completely enclosed inside the outer shell of the temple body. The outer surfaces of the inner and outer sides of the temples are continuous and closed insulating material surfaces (such as plastic, resin, or ceramic), with no metal contacts or sensing holes on the surface. The wearing detection component 2307b identifies the wearing status by sensing the change in the edge electric field generated when human tissue approaches. The induced electric field penetrates the thickness of the temple shell (e.g., 0.5mm to 1.0mm) and acts on the user's skin. Because the conductive pad does not directly contact the skin, the electrochemical corrosion of the metal electrodes by sweat and oil during wear is reduced, allowing the system to easily achieve IP67 or higher water resistance. No openings or conductive metal inlays are needed on the temple surface, maintaining a consistent appearance. When operating, sliding, or wearing the glasses, the user comes into contact with a smoother, more tactile shell material, avoiding the risk of metal allergies.

[0103] In some embodiments, the interactive control component 2307a may include a capacitive sensing plate disposed on the outer side of the temple, used to identify click, double-click, long press, or sliding operation along the temple axis by detecting the capacitance change generated when a human finger approaches or touches the temple. Optionally, the interactive control component 2307a may include a mechanical button, dial, or microswitch, generating an on / off signal through physical displacement. The mechanical button can serve as a hard reset switch or a high-frequency confirmation operation item for the system. Optionally, the interactive control component 2307a may include an induction coil, using the principle of inductive induction to identify minute deformations of the metal shell. This method is particularly suitable for temples with a fully sealed, waterproof design, where the user can trigger interactive commands by pressing the metal shell of the temple. Optionally, the interactive control component 2307a may include a piezoelectric sensor, thin-film pressure gauge, or strain gauge, used to sense the force of the user pressing the temple. By setting different pressure thresholds, the system can distinguish between "light touch" and "hard press," thereby achieving multi-level functional expansion in the same physical location. Optionally, the interactive control component 2307a may include an infrared photodiode, an ambient light sensor, or a miniature laser rangefinder module to recognize finger hovering or hand gestures near the temples by detecting changes in light intensity through occlusion or reflection. Optionally, the interactive control component 2307a may include a MEMS inertial measurement unit such as an accelerometer or gyroscope. Users can interactively control the glasses by tapping the temples (generating specific vibration characteristics) or by shaking their heads at a specific frequency.

[0104] In some embodiments, referring to FIG33, the near-eye display device 200a may further include a sensing control chip 2309, which is electrically connected to the processor 2301, for example, via a standard I2C communication interface. The interaction control component 2307a and the wear detection component 2307b are both electrically connected to the sensing control chip 2309. It is understood that the inner first conductive sheet 224 and the second conductive sheet 226 are electrically connected to the differential sensing pins of the sensing control chip 2309, and the electrical signal generated by the outer interaction control component 2307a is transmitted to the touch input pin. The sensing control chip 2309 utilizes its built-in sensing engine to perform digital conversion, noise filtering, and automatic calibration processing on the raw signal. Internally, the chip performs gesture algorithm calculations on the touch signal (such as determining the sliding direction and displacement) and makes logical determinations regarding the wearing status. It is understood that the system can provide multiple power consumption modes: dynamic mode, monitoring mode, and deep sleep mode. When the wear detection component senses that the user is not wearing glasses, the sensor control chip 2309 notifies the processor 2301 to put the system into an ultra-low power mode. Once wearing behavior is detected, the system quickly switches to dynamic mode, monitoring the sliding events of the outer interactive control component 2307a in real time. The processor 2301 reads the event register (e.g., address 0x11) of the sensor control chip 2309. Only when the wearing status is determined to be "wearing" will the processor 2301 respond to the sliding control command generated by the outer interactive control component 2307a, thereby avoiding accidental touches when the user removes the glasses or holds the temples. By managing both internal and external sensors simultaneously through the sensor control chip 2309, the PCB size is reduced, making it suitable for the compact space of the glasses temples. The aforementioned three-tier architecture of "sensing end - preprocessing end - system main control end" realizes "link integration" of signals. The processor 2301 does not need to directly process the cumbersome raw capacitor signals, but only needs to receive digital instructions output by the sensing control chip 2309 (such as "wearing successful" or "slide 10 units"), which greatly saves the main control's computing resources and I / O port occupation, and ensures the accuracy of control instructions in complex environments.

[0105] In some embodiments, the interactive control component 2307a may also perform preliminary signal acquisition and noise reduction processing via a dedicated low-power touch chip (not shown) before transmitting the data to the sensing control chip 2309. The touch chip supports self-interoperability detection and can provide a higher signal-to-noise ratio.

[0106] In some embodiments, memory 2302 may include high-speed random access memory or non-volatile memory, such as one or more disk storage devices, one or more optical storage devices, or flash memory. It stores N instruction sets for processing basic system services and performing hardware-related tasks; these instruction sets may be instruction sets used to facilitate processing of related sensors or interfaces. Memory 2302 may also store an operating system, such as Darwin, RTXC (Real-Time Multiprocessor Execution System), LINUX, UNIX, Android, iOS, WINDOWS, or other embedded operating systems. Memory 2302 stores one or more programs configured to be executed by the one or more processors 2301, the one or more programs including instruction sets for operation.

[0107] In some embodiments, transceiver 2303 may include wireless communication, including radio frequency receivers and transmitters and / or optical (e.g., infrared) receivers and transmitters, designed to operate through a global system targeting one or a combination of mobile communication (GSM) networks, GPRS networks, enhanced data GSM environment (EDGE) networks, IEEE 802.xx communication networks (e.g., WiFi, WiMax, ZigBee™), 3G, 4G, 4G LTE, 5G, code division multiple access (CDMA) networks, near field communication (NFC), WiFi Direct, infrared, and Bluetooth networks. The wireless communication unit may include managed protocols to enable the device to be configured as a base station for other wireless devices. For example, the communication subsystem may allow the device to synchronize with the host device using one or more protocols or communication technologies, such as TCP / IP (Transmission Control Protocol / Internet Protocol), HTTP (Hypertext Transfer Protocol), UDP (User Datagram Protocol), ICMP, POP (Post Office Protocol), FTP (File Transfer Protocol), and DCOM (Distributed Component Object Model) or any other known communication protocol or technology.

[0108] Figure 17 illustrates a network environment application example of the near-eye display device 200a. It includes the near-eye display device 200a, an external terminal device 300a, and an external or local cloud computing platform or server 400a. The near-eye display device 200a can first communicate with the terminal device 300a via a wireless network such as a transceiver 2303. The terminal device 300a then communicates with the external or local cloud computing platform or server 400a, thereby enabling the near-eye display device 200a to communicate with the external or local cloud computing platform or server 400a. The near-eye display device 200a, the (external) terminal device 300a, and the server 400a can each be used to store and process content data received or uploaded by the near-eye display device 200a; in some embodiments, the near-eye display device 200a can directly communicate with the server 400a via a wireless or wired network. The near-eye display device 200a can be a portable, mobile, lightweight device, such as smart glasses or augmented reality devices. It may include a near-eye display module 100a. The terminal device 300a can be a smartphone, laptop, tablet, or desktop computer. In some embodiments, the near-eye display devices 200a can also communicate with each other. In other embodiments, the near-eye display devices 200a can also communicate with wearable interactive devices such as smart rings, bracelets, or controllers. Interactive operations on the near-eye display devices 200a can be achieved through such interactive devices, such as page turning, page swiping, selection, or confirmation.

[0109] The following description, in conjunction with Figures 18-30, describes a near-eye display device of this application, including a device body 100, a near-eye display mechanism 300, a locking mechanism 500, and a camera module 700. The device body 100 has a near-eye side C and an ambient side D. It should be noted that, in this embodiment, the first direction of the device body 100 is the direction from the near-eye side C to the ambient side D, which can be understood as the longitudinal direction of the device body 100 in the front-back direction; the second direction of the device body 100 can be a direction perpendicular to the first direction, which can be understood as the lateral direction of the device body 100 in the left-right direction.

[0110] Referring to Figures 18 to 22, in this embodiment, the device body 100 is provided with a first connecting structure 200, the near-eye display mechanism 300 is configured to generate light and project it onto the human eye, the near-eye display mechanism 300 is provided with a second connecting structure 400, the first connecting structure 200 and the second connecting structure 400 are movably connected, the locking mechanism 500 is movably connected to the second connecting structure 400, the locking mechanism 500 moves relative to the second connecting structure 400, and has at least a first position and a second position; wherein, when the locking mechanism 500 is in the first position, the locking mechanism 500 acts on the second connecting structure 400 to lock the relative position of the first connecting structure 200 and the second connecting structure 400; when the locking mechanism 500 is in the second position, the locking mechanism 500 releases its action on the second connecting structure 400, the first connecting structure 200 and the second connecting structure 400 move relative to each other, and allow adjustment of the angle between the near-eye display mechanism 300 and the device body 100. By providing a first connecting structure 200 to the main body 100 of the device and a second connecting structure 400 to the near-eye display mechanism 300, the first connecting structure 200 and the second connecting structure 400 are movably connected and fixedly engaged with the locking mechanism 500 and the second connecting structure 400. Users can fix or adjust the angle between the near-eye display mechanism 300 and the main body 100 of the device by operating the locking mechanism 500, thereby achieving different angle adjustments to meet the user's viewing needs.

[0111] It is understood that, referring to Figures 18 to 20 and Figure 23, in this embodiment of the application, the main body 100 of the device includes a frame 130 and two temples 140. The frame 130 is used to mount the lens 150, and the two temples 140 are respectively connected to both sides of the frame 130. A cavity 110 is provided inside the frame 130. The locking mechanism 500 and the first connecting structure 200 are both located inside the cavity 110. A part of the second connecting structure 400 and the near-eye display mechanism 300 are located outside the cavity 110, and another part of the second connecting structure 400 extends into the cavity 110. It is understood that the frame 130 can be located on the environmental side D. The frame 130 can be provided with through holes at the positions corresponding to the first connecting structure 200, the second connecting structure 400, or the locking mechanism 500, so that the user can adjust the locking mechanism 500 with tools or hands to achieve the movable connection between the first connecting structure 200 and the second connecting structure 400. In other embodiments, the locking mechanism 500 can also be adjusted from the side C closest to the human eye.

[0112] With the above structure, the existence of chamber 110 provides suitable space for each component, allowing each connecting structure and component to be embedded therein. The distribution of components inside and outside chamber 110 is reasonable, which not only ensures the overall compactness of the structure, but also allows key components to be properly protected and isolated, thus ensuring the functionality and stability of the equipment.

[0113] It should be noted that in this embodiment, an operating recess or through hole communicating with the chamber 110 is provided on the front side of the frame 130 in the first direction, and a cover is detachably provided in the operating recess. In the normal state where no adjustment is required, the cover covers the recess or through hole at the position of the frame corresponding to the first connecting structure 200, the second connecting structure 400, or the locking mechanism 500. The operating recess or through hole is correspondingly set with the locking mechanism 500. By removing the cover from the frame 130, the locking mechanism 500 in the chamber 110 can be operated. After the operation is completed, the cover can be snapped into the operating recess of the frame 130. The structure is simple, the disassembly and assembly are convenient, and it is convenient for users to operate the locking mechanism 500 to adjust the near eye display mechanism 300.

[0114] Specifically, referring to Figures 18 to 22, in this embodiment, the first connecting structure 200 and the second connecting structure 400 are inserted and rotated together. The device body 100 has a near-eye side C and an environmental side D. The locking mechanism 500 is located on the side of the frame 130 of the device body 100 away from the near-eye side C. When the locking mechanism 500 moves to the first position, it acts on the second connecting structure 400, and the first connecting structure 200 and the second connecting structure 400 are pressed together and fixed. When the locking mechanism 500 moves to the second position, it releases its action on the second connecting structure 400, and there is a gap between the first connecting structure 200 and the second connecting structure 400, allowing relative rotation to adjust the angle of the near-eye display mechanism 300 relative to the frame 130 of the device body 100.

[0115] With the above structure, when the locking mechanism 500 moves to the first position, it applies force to the second connecting structure 400, thereby securing the first connecting structure 200 and the second connecting structure 400 together. This securing action ensures a stable connection between the two connecting structures and prevents unnecessary movement between them. When the locking mechanism 500 moves to the second position, it releases the securing action on the second connecting structure 400, allowing a gap between the first connecting structure 200 and the second connecting structure 400. This gap allows the user to adjust the angle of the near-eye display mechanism 300 relative to the frame 130 of the device body 100 by adjusting the relative position of the first connecting structure 200 and the second connecting structure 400. Structurally, this achieves both fixing and angle adjustment functions. Through the locking and unlocking mechanism, users can easily adjust the angle of the near-eye display mechanism 300 relative to the device body 100 to achieve a better visual experience and user comfort.

[0116] Specifically, referring to Figures 18 to 22, in this embodiment of the application, the first connecting structure 200 and the second connecting structure 400 are slidably engaged; when the locking mechanism 500 is in the first position, the locking mechanism 500 acts on the second connecting structure 400, restricting the relative sliding of the second connecting structure 400 and the first connecting structure 200; when the locking mechanism 500 is in the second position, the locking mechanism 500 releases its action on the second connecting structure 400, and the second connecting structure 400 and the first connecting structure 200 slide relative to each other.

[0117] With the above structure, the first connecting structure 200 and the second connecting structure 400 can not only rotate relative to each other, but also slide relative to each other. Similarly, through the locking and unlocking mechanism, the user can easily adjust the position of the near-eye display mechanism 300 relative to the frame 130 of the device body 100 to achieve a better visual experience and user comfort.

[0118] Of course, in some embodiments, the first connecting structure 200 and the second connecting structure 400 can only be rotated relative to each other and cannot be slidably connected, which is not limited here.

[0119] It is understood that, referring to Figures 19 to 22, in the embodiments of this application, the first connecting structure 200 includes an abutment wall 210, one end of which is connected to the inner wall of the chamber 110 of the device body 100, and the abutment wall 210 forms a mounting position 220; the second connecting structure 400 includes a base 410 and an expansion portion 420, the base 410 is connected to the near-eye display mechanism 300, the expansion portion 420 is connected to the side of the base 410 away from the near-eye display mechanism 300, a mounting groove 430 is formed between the expansion portion 420 and the base 410, the expansion portion 420 is inserted into the mounting position 220, and the expansion portion 420 corresponds to and cooperates with the abutment wall 210; the locking mechanism 500 is movably connected to the base 410, the locking mechanism 500 is located in the mounting groove 430, and the locking mechanism 500 is configured to allow the expansion portion 420 to expand relative to the base 410 and abut against the abutment wall 210.

[0120] With the above configuration, the expansion part 420 is inserted into the mounting position 220 of the abutment wall 210, and the expansion part 420 and the abutment wall 210 cooperate accordingly to ensure a stable connection between the first connecting structure 200 and the second connecting structure 400. The movement of the locking mechanism 500 can control the movement of the expansion part 420, allowing the user to adjust the angle and position of the near-eye display mechanism 300 relative to the main body 100 of the device. The above design provides flexibility, allowing users to adjust the angle of the device according to their personal needs and comfort, thus improving the user experience. It takes into account both the needs of fixation and adjustability. Through the action of the locking mechanism 500, the connecting structure can be fixed when needed to maintain stability; and when the angle needs to be adjusted, the locking mechanism 500 can be released to achieve flexible angle adjustment. Users can control and adjust the expansion part 420 through simple operations, such as driving the locking mechanism 500, without complicated tools or operating procedures.

[0121] Specifically, referring to Figures 19 to 22, in this embodiment of the application, the locking mechanism 500 includes a connecting portion 510 and a driving portion 520 connected to the connecting portion 510. The connecting portion 510 is movably connected to the base 410. The driving portion 520 is configured to follow the connecting portion 510 to move into the mounting groove 430 and expand the expansion portion 420 to abut against the abutment wall 210. The driving portion 520 is also configured to follow the connecting portion 510 to move out of the mounting groove 430 and space the expansion portion 420 from the abutment wall 210.

[0122] The above settings enable the release and adjustment functions, making locking and releasing operations more convenient. Users can control the drive unit 520 through simple operations to move the connecting unit 510 and switch functions without complicated steps or tools, providing flexibility and allowing users to select the locking or releasing state as needed, thereby achieving fixation or adjustment between the first connecting structure 200 and the second connecting structure 400.

[0123] It should be noted that in this embodiment, the locking mechanism 500 is a locking bolt, that is, the connecting part 510 is the threaded shank of the locking bolt and bolts into the base 410, and the driving part 520 is the head of the locking bolt. Of course, in some embodiments, the locking mechanism 500 can also be other structures, such as a snap-fit ​​component that engages with the base 410, etc., which is not limited here.

[0124] Specifically, referring to Figures 19 to 22, in this embodiment of the application, the inner side of the abutment wall 210 is provided with a first arc-shaped surface 211, and the side of the expansion portion 420 opposite to the mounting groove 430 is provided with a second arc-shaped surface 421. The first arc-shaped surface 211 and the second arc-shaped surface 421 are in one-to-one correspondence and fit together, and the width of the driving portion 520 is greater than the minimum spacing of the mounting groove 430.

[0125] With the above structure, the first arc-shaped surface 211 and the second arc-shaped surface 421 are set to match, ensuring the stability and correct positioning of the connection, so that the first connecting joint and the second connecting structure 400 rotate or slide relatively smoothly and stably. Since the driving part 520 has a large width, when the driving part 520 moves with the connecting part 510, it can squeeze into the mounting groove 430 with the minimum spacing and push the expansion part 420 to abut and press against the abutment wall 210, or move away from the mounting groove 430 to restore the state of the expansion part 420. The setting of the width of the upper driving part 520 and the corresponding spacing of the mounting groove 430 can firmly control the position of the expansion part 420, providing better positioning and operational stability, and ensuring the accuracy and stability of the connection.

[0126] Specifically, referring to Figures 19 to 22, in this embodiment, there are two expansion portions 420, each facing away from the near-eye side C and extending along a second direction. The mounting position 220 is located between the near-eye side C and the environmental side D. There are also two abutment walls 210, which together form the mounting position 220, located between the near-eye side C and the environmental side D, extending along the second direction. Each expansion portion 420 corresponds to one of the two abutment walls 210, and the expansion portion 420 is slidably connected to the mounting position 220 along the second direction. This structure further improves the installation stability of both the first connecting structure 200 and the second connecting structure 400.

[0127] Of course, in some embodiments, the expansion portion 420 and the abutment wall 210 may be one or three, etc., and this is not limited here.

[0128] As can be understood, referring to Figures 23 to 25, in this embodiment, the near-eye display device includes a control circuit board 610 and a first conductive line 620. The control circuit board 610 is disposed on the temple 140, and the near-eye display mechanism 300 is electrically connected to the control circuit board 610 through the first conductive line 620. A positioning structure 120 is provided in the cavity 110, and the first conductive line 620 is located in the cavity 110. The first conductive line 620 and the positioning structure 120 are wound around and cooperate with each other. The near-eye display mechanism 300 is configured to move close to the positioning structure 120, and the first conductive line 620 is allowed to bend to form a stacked segment 621. The stacked segment 621 is located between the positioning structure 120 and the near-eye display mechanism 300. With the above structure, since the first conductive wire can bend around the positioning structure 120 to form a stacked end after bypassing the positioning structure 120, the first conductive wire has a certain redundant length. Therefore, the first conductive wire 620 is allowed to slide in the second direction, i.e., laterally, avoiding damage when the first conductive wire 620 needs to slide laterally, thus improving durability.

[0129] Specifically, referring to Figures 23 to 25, in this embodiment of the application, the near-eye display device further includes a first battery 630 and a second conductive line 640; a control circuit board 610 is disposed in one of the temples 140, the first battery 630 is disposed in the other temple 140, the second conductive line 640 is located in the cavity 110, one end of the second conductive line 640 is electrically connected to the control circuit board 610, and the other end of the second conductive line 640 is electrically connected to the first battery 630.

[0130] With the above structure, it can be understood that the cavity 110 spans the left and right visual field of the frame 130, and the second conductive line 640 is arranged in the cavity 110 and electrically connected to the control circuit board 610 and the first battery 630 respectively. This makes full use of the internal space of the frame 130, so that the second conductive line 640 can be arranged in an orderly manner inside the cavity 110, avoiding the second conductive line 640 being messy and exposed, thus providing effective protection, reducing the interference of the external environment on the second conductive line 640, improving the reliability and durability of the overall structure, and ensuring the stability and reliability of signal transmission.

[0131] Specifically, referring to Figures 19 to 24, in this embodiment, the near-eye display mechanism 300 includes a mounting assembly 310, a display module 320, and an optical module 330 disposed on one side of the display module 320. Both the display module 320 and the optical module 330 are mounted on the mounting assembly 310. The display module 320 generates light, and the optical module 330 is configured to receive the light from the display module 320 and project it onto the human eye. A second connecting structure 400 is disposed on the side of the mounting assembly 310 opposite to the optical module 330. The display module 320 is electrically connected to the control circuit board 610 via a first conductive line 620. With this configuration, when the display module 320 moves toward the positioning structure 120, the first conductive line 620 is flattened and folded by the positioning structure 120, forming a stacked segment 621. This prevents excessive bending and tangling of the first conductive line 620, thus ensuring that damage to the first conductive line 620 is avoided during lateral sliding.

[0132] It should be noted that, referring to Figures 23 and 24, in this embodiment, the positioning structure 120 includes a first positioning post 121 and a second positioning post 122. The first positioning post 121 is located below the second positioning post 122. One end of the second positioning post 122 is provided with a transition block, which is sleeved on the first positioning post. There is a wire passage gap between the second positioning post 122 and the inner wall of the cavity 110. Therefore, the first conductive wire 620 can pass through the wire passage gap and overlap around the second positioning post 122 to form a stacked section 621. The stacked section 621 is located on the other side of the second positioning post 122 away from the wire passage gap, and the upper side of the transition block can support the bottom of the first conductive wire 620. Of course, in some embodiments, the positioning structure 120 may only include the second positioning post 122. The second positioning post 122 may be formed by extending downward from the upper wall of the cavity 110 of the frame 130. Therefore, it is not necessary to provide a transition block and the first positioning post 121.

[0133] Specifically, referring to Figures 23 and 24, in this embodiment of the application, the mounting component 310 includes a base 311 and a cover plate 312, the cover plate 312 is connected to the base 311, the optical module 330 is disposed on the base 311, and the second connection structure 400 is disposed on the cover plate 312; the display module 320 includes a microdisplay 321, a driving board 322 and a third conductive line 323, the microdisplay 321 is disposed between the base 311 and the cover plate 312, the driving board 322 and the microdisplay 321 are electrically connected through the third conductive line 323, and the driving board 322 and the control circuit board 610 are electrically connected through the first conductive line 620.

[0134] The above structure allows the optical module 330 and the second connection structure 400 to be located on different components, facilitating maintenance and replacement. The microdisplay 321 is placed between the base 311 and the cover plate 312, and the modules are electrically connected through conductive lines. The reasonable module layout and stable and reliable connection provide effective guarantees for the functionality and reliability of the device.

[0135] It is understood that, referring to Figures 26 to 29, in this embodiment of the application, the frame 130 of the device body 100 is provided with a first mounting area 160 and a second mounting area 170, which are spaced apart. The second mounting area 170 is used to mount the lens 150. The near-eye display mechanism 300 is disposed in the second mounting area 170 and is configured to generate light and project it onto the near-eye side C. The camera module 700 is configured to be detachably connected to the first mounting area 160 of the device body 100. When the camera module 700 is located in the first mounting area 160, the camera module 700 faces the environment side D away from the near-eye side C to acquire the image of the environment side D. The camera module 700 does not overlap with the lens 150 in the first direction.

[0136] This application provides a near-eye display device, which clearly divides the device body 100 into a first mounting area 160 and a second mounting area 170, thereby achieving a clear division of the mounting areas for different components. The first mounting area 160 is specifically used to mount the camera module 700, while the second mounting area 170 is used to mount the lens 150 and the near-eye display mechanism 300. By detachably mounting the camera module 700 to the first mounting area 160 of the device body 100, it can be easily installed or removed, facilitating maintenance, replacement, or upgrades. The aforementioned detachable connection design provides flexibility and convenience, and helps to avoid visually obtrusive issues.

[0137] Specifically, referring to Figures 26 to 29, in this embodiment, the near-eye display mechanism 300 does not overlap with the lens 150 in the first direction, and the near-eye display mechanism 300 is located between the near-eye side C and the environment side D; there are two second mounting areas 170, which are located on both sides of the first mounting area 160 respectively, and the height of the first mounting area 160 is lower than that of the second mounting area 170. At least one second mounting area 170 is provided with the near-eye display mechanism 300; wherein, the frame 130 of the device body 100 is provided with a mounting cover 133 corresponding to the second mounting area 170, and a mounting cavity is provided between the housing 730 and the second mounting area 170. The display module 320 of the near-eye display mechanism 300 is located in the mounting cavity, and the end of the optical module 330 extends to the end face of the mounting cover 133. The first mounting area 160 forms a recess extending in the second direction, and the camera module 700 forms a protrusion that matches the shape of the recess. The above structure not only provides some protection for the near-eye display mechanism 300, preventing it from being exposed, but also achieves a visually balanced and symmetrical design aesthetic through the recess of the first mounting area 160 and the protrusion of the camera module 700, which helps to avoid the problem of being too abrupt and achieves a hidden effect.

[0138] Specifically, referring to Figures 26 to 29, in this embodiment, the first mounting area 160 is located in the middle of the frame 130 of the device body 100; a magnetic attraction structure is provided between the device body 100 and the camera module 700, the magnetic attraction structure includes a first magnetic attraction part 180 and a second magnetic attraction part 710, the first magnetic attraction part 180 is located in the frame 130 of the device body 100 and is located in the first mounting area 160, the second magnetic attraction part 710 is located in the camera module 700, the first magnetic attraction part 180 and the second magnetic attraction part 710 are correspondingly arranged and mutually attracted.

[0139] With the above configuration, the first magnetic part 180 and the second magnetic part 710 attract each other to provide a secure connection. This design makes installation and removal more convenient and quick, while ensuring the stability and reliability of the connection, providing users with a better user experience.

[0140] Specifically, referring to Figures 26 to 29, in this embodiment, the first magnetic attraction part 180 and the second magnetic attraction part 710 are magnets with opposite magnetic properties; or, one of the first magnetic attraction part 180 and the second magnetic attraction part 710 is a magnet, and the other of the first magnetic attraction part 180 and the second magnetic attraction part 710 is an iron part; wherein, there are two first magnetic attraction parts 180 and two magnetic attraction parts 710, the two first magnetic attraction parts 180 are spaced apart along the second direction in the first mounting area 160, and the two second magnetic attraction parts 710 are spaced apart on opposite sides of the camera module 700. By using magnets with different magnetic properties or a combination of magnets and iron parts, the connection structure is more flexible and reliable. The connection between the frame 130 of the main body 100 and the camera module 700 can be completed quickly, and it is easy to disassemble and maintain while maintaining stability. There are two of each of the first magnetic attraction part 180 and the second magnetic attraction part 710, which are respectively arranged at intervals along a specified direction on the frame 130 of the main body 100 and the camera module 700. The above arrangement helps to ensure the stability and balance of the connection and reduces deviation and instability during the connection process.

[0141] Of course, in some embodiments, the first magnetic attraction part 180 and the second magnetic attraction part 710 may be one, three, etc., without limitation.

[0142] Specifically, referring to Figures 26 to 29, in this embodiment, a fixing structure is provided between the camera module 700 and the device body 100. The fixing structure includes a first fixing part 190 and a second fixing part 720. The first fixing part 190 is disposed on the device body 100 and is located at the first mounting area 160. The second fixing part 720 is disposed on the camera module 700. The first fixing part 190 and the second fixing part 720 are correspondingly disposed and inserted into each other. One of the first fixing part 190 and the second fixing part 720 is a fixing groove, and the other of the first fixing part 190 and the second fixing part 720 is a fixing protrusion. The fixing protrusion is inserted into the fixing groove.

[0143] The above structure, through the combination of fixed groove and fixed protrusion, not only has a simple structure and is easy to manufacture, but also achieves a stable connection. This makes the installation between the frame 130 of the main body 100 and the camera module 700 more secure and reliable, providing better stability and reliability for the use of the equipment.

[0144] Referring to Figure 29, the frame 130 may also include a first connector 810 and a second connector 820, which cooperate to detachably connect the upper frame 131 and the lower frame 132.

[0145] It is understood that, referring to FIG30, in the embodiment of this application, the camera module 700 includes a housing 730, an image sensing unit 740 and a second battery 750, wherein the second battery 750 is electrically connected to the image sensing unit 740; wherein, the second battery 750 is not electrically connected to the control circuit board 610 and the first battery 630, so that the camera module 700 can work independently.

[0146] In other embodiments, the camera module 700 includes a housing 730, an image sensing unit 740, and a first electrical interface; the first mounting area 160 is also provided with a second electrical interface. When the camera module 700 is configured to be located in the first mounting area 160, the first electrical interface and the second electrical interface are electrically connected to connect the image sensing unit 740 to the control circuit board 610 and the first battery 630, so that the camera module 700 can be detachably and electrically connected to other electrical components of the cavity 110 of the frame 130, so that the various modules are interconnected.

[0147] Specifically, referring to Figures 27 and 28, in this embodiment, the eyeglass frame 130 includes an upper frame 131 and a lower frame 132 connected to the upper frame 131. The upper frame 131 and the lower frame 132 cooperate to form two second mounting areas 170, and a first mounting area 160 is located in the middle of the upper frame 131. A portion of the lower frame 132 is rotatably connected to the upper frame 131, and another portion is detachably connected to the upper frame 131. The lower frame 132 includes two lower frame members 1321, one end of which is rotatably connected to the upper frame 131, and the other end of which is detachably connected to the upper frame 131. Each lower frame member 1321 and a portion of the upper frame 131 surround and mounts a lens 150. With this configuration, the upper frame 131 and the lower frame 132 form a semi-open structure, facilitating easy lens replacement for the user.

[0148] It should be noted that, in this embodiment, the front frame and the rear frame of the mirror frame 130 constitute the upper frame 131, and the rotational connection and opening method of the upper frame 131 and the lower frame 132 can be interchanged left and right.
