[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technical workers in the field without making creative work are within the scope of protection of this application.

[0036] The terms "first", "second" and "first" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first" and "second" can expressly or implicitly include at least one of the features. All directional indications (such as up, down, left, right, front, back ...) in the embodiments of the present application are only used to explain the relative position relationship, movement conditions, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices. The term "and / or" is used to describe the association relationship of associated objects, indicating that there can be three relationships; for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0037] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments. With respect to the description of the drawings, the same or similar parts may be marked by the same or similar reference numerals.

[0038] In some application scenarios, smart glasses such as optical waveguides often integrate batteries and circuit boards on the same temple. Then, in order to balance the weight of the left and right temples, it is often necessary to add additional weights to the other temple, which makes the entire glasses heavier and not conducive to long-term wear. On the other hand, during long-term use of existing smart glasses, the long-term rotation of the temples can easily cause electrical wires to be exposed or damaged.

[0039] Combined with reference Figure 1-16 The present application proposes a near-eye display device 200, which includes a frame 10, and the frame 10 is provided with a first cavity 101. The near-eye display device of the present application can be a smart device such as smart glasses, AR (Augmented Reality), VR (Virtual Reality) or MR (Mixed Reality).

[0040] The near-eye display module 100 is provided in the frame 10. The near-eye display module 100 may be at least partially contained in the first cavity 101 and partially leaked relative to the first cavity 101. The near-eye display module 100 may be configured to allow movement relative to the frame 10, such as sliding or rotating. In other embodiments, the near-eye display module 100 may 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 100 is used to generate light to be projected to the near-eye side 102, and digital content may be projected to the user's eyes at the near-eye side 102. The near-eye display module 100 may use binocular parallax, integrated imaging, holographic technology, or retinal imaging technology, etc. to realize the projection of digital content into the human eye.

[0041] In some embodiments, the near-eye display device 200 may further include a lens 105 disposed on the frame 10. In some embodiments, the frame 10 may further include an upper frame 13 and a lower frame 14, and the lens 105 may be installed between the upper frame 13 and the lower frame 14. The lens 105 may be detachably connected to the frame 10 to allow the user to replace lenses with different vision corrections. Of course, the lens 105 may also be fixedly connected to the frame 101 without being allowed to be disassembled by the user. The near-eye display module 10 may be set as a single or as two or more. In some embodiments, the lens 105 may be a plano lens, a sun lens or a protective lens. In other embodiments, the lens 105 may be a lens with vision correction, such as a lens for correcting specific eyes or people with vision defects such as myopia, hyperopia, color blindness, etc. The lens 105 may be spherical, aspherical, toroidal, cylindrical, single-vision, multifocal, progressive, and / or adjustable. In some embodiments, the projection area of ​​the near-eye display module 10 does not overlap with the lens 105 in the direction from the near-eye side 102 to the world side 103, thereby reducing the interference of the near-eye display module 10 on the normal field of view of the lens 105. In other embodiments, the projection area of ​​the near-eye display module 10 partially overlaps with the lens 105 in the direction from the near-eye side 102 to the world side 103, or the near-eye display module 10 can also be configured to move to the area of ​​the lens 105, that is, allowing the near-eye display module 10 to be adjusted at a predetermined or arbitrary position of the lens 105.

[0042] The first limiting part 210 is connected to the frame 10. The first limiting part 210 can be connected to the frame 10 by bonding, clamping, hinged, or fixedly connected with fasteners. The materials of the first limiting part 210 and the frame 10 can be the same or different. The first limiting part 210 is provided with a first through hole 201, and the first through hole 201 is connected to the first cavity 101. The first temple 220 is provided with a second cavity 221. The first electrical device 230 is provided in the second cavity 220. The first electrical device 230 can include a circuit board. Referring to the system block diagram, the circuit board can be hard or flexible. The circuit board can be one piece or multiple pieces electrically connected to each other. The circuit board 230 can include peripheral devices 2308 such as a processor 2301, a memory 2302, external capacitors / resistors / inductors, and the like, and an operating unit 2307 such as a switch / control button, and the like. In some embodiments, electrical devices such as a microphone 2304 or a vital sign / ambient light / brightness sensor 2306 may also be disposed in the second cavity 220 .

[0043] The second limiting portion 240 is connected to the first temple 220. The second limiting portion 240 can be connected to the first temple 220 by bonding, clamping, hinged, or fixedly connected with fasteners. The second limiting portion 240 is provided with a second through hole 241. The second through hole 241 can be understood as a groove or a groove or a through groove or a mounting groove, etc., which allows the placement or the passage of components therein. The second limiting portion 240 is rotatably connected to the first limiting portion 210. The second limiting portion 240 and the first limiting portion 210 can be hinged, swivel jointed, spring hinged, etc., that is, the first temple 220 is rotatably connected to the frame 10 through the second limiting portion 240 and the first limiting portion 210. 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 wire 250 passes through the first through hole 201 and the second through hole 241 and electrically connects the near-eye display module 100 and the first electrical device 230.

[0044] The second temple 260 is provided with a third cavity 261, and the second temple 260 is rotatably connected to the frame 10. Among them, the first temple 220 can be rotatably connected to the frame 10, and in other embodiments, the first temple 220 can also be fixedly connected to the frame 10. The second electrical device 232 is provided in the third cavity 260, and the second electrical device 232 can be a power module, for example, a rechargeable or replaceable battery through the charging interface 2322. The second wire 252 extends laterally along the frame 10, and the lateral extension can be understood as the direction across the left and right lenses 105, that is, the direction of the left and right glasses corresponding to the human eye after the device 200 is worn. The second wire 252 passes through the first through hole 201 and the second through hole 241 and electrically connects the second electrical device 232 and the first electrical device 230. The first wire 250 and the second wire 252 can be flexible electrical wires, which can be bent, curved or folded; in another embodiment, the first wire 250 can be a flexible wire, and the second wire 252 can be a non-flexible wire. The first wire 250 and the second wire 252 may be printed with an electrical conduction circuit. The first wire 250 and the second wire 252 may be long flat strips, or in some other embodiments may be long cylindrical strips, or may be multiple thin long cylindrical strips arranged side by side. The overlapping portions of the projections of the first wire 250 and the second wire 252 on the frame 10 may be insulated from each other. The insides of the first wire 250 and the second wire 252 may be printed with metal (such as copper, etc.) conductive circuits, and the surfaces of the two wires may be coated with insulating materials, that is, the two may contact each other without causing an electrical short circuit. The frame 10 and the temple shell may be made of plastic material, and the first limit portion 210 and the second limit portion 240 may be made of metal material as a whole.

[0045] By setting the near-eye display module 100 on the frame 10, setting the first electrical device 230 on the first temple 220, and setting the second electrical device 232 on the second temple 260, the weight of the entire device 200 can be effectively balanced without the need for additional counterweight devices. In addition, the first wire 250 electrically connects the near-eye display module 100 and the first electrical device 230, and the second wire 252 extends horizontally and electrically connects the near-eye display module 100 and the second electrical device 232. The first wire 250 and the second wire 252 are both passed through the first through hole 20 1 and the second through hole 241 can effectively reduce the exposure of the two wires, effectively reduce the wear of the wires during use, and set the battery or the like as the second electrical device 232 separately in the second temple 260, and use the second electrical device 232 and the first electrical device 230 to be electrically connected by the transversely extended second wire 252, so that the space of each temple can be fully utilized. For example, the second temple 260 can allow a battery with a larger capacity to be placed, and is electrically connected to the near-eye display module 100 through the extended second wire 252, thereby effectively improving the battery life of the device.

[0046] In some embodiments, see Figure 2-5 , the length of the first wire 250 is less than the length of the second wire 252, the near-eye display module 100 is configured to allow movement on the frame 10, and the user can touch the near-eye display module 100 with a finger or a tool to achieve movement. The first wire 250 moves at least partially in the first cavity 101 when the near-eye display module 100 moves relative to the frame 10, and the movement of the first wire 250 can be understood as the first wire 250 being bent, folded or stretched, and unfolded. When the user operates the near-eye display module 100 to slide in the direction close to the first temple 220, the first wire 250 can be bent or folded, causing the first wire 250 to be retracted or rolled up and located in the first cavity 101; when the user operates the near-eye display module 100 to slide in the direction away from the first temple 220 and close to 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 glue filling, bonding, clamping or connecting with a fixing member. During the movement of the near-eye display module 100, only a part of the first wire 250 is rolled up or stretched, while the second wire 252 is not affected by this, effectively ensuring the stability of their respective electrical connections. The first wire 250 and the second wire 252 are electrically insulated from each other in the overlapping part in the extension direction. It can be understood that at the position of the first cavity 101, the first through hole 201 and the second through hole 241, as viewed in the projection direction from the near-eye side 102 to the environmental side 103, the first wire 250 and the second wire 252 at least partially overlap with each other. For example, the first wire 250 and the second wire 252 both use a flat flexible circuit board. The first wire 250 and the second wire 252 can be made of polyester, polyethylene naphthalate, polyimide or liquid crystal polymer. In some embodiments, a metal conductive layer is printed inside the first wire 250 and the second wire 252, and the surfaces of the two wires can also be coated with insulating materials respectively. The surfaces of the first wire 250 and the second wire 252 are electrically insulated from each other, and the two wires will not conduct electricity even if they are in direct surface contact, which is conducive to ensuring the independence of their respective electrical circuits and reducing the risk of short circuits.

[0047] In some embodiments, in combination with Figure 2-5The first wire 250 may be provided with a first clamping hole 2501, and the second wire 252 may be provided with a second clamping hole 2521. The first clamping hole 2501 and the second clamping hole 2521 may be of the same size and shape, and the electrically conductive layers on the first wire 250 and the second wire 252 may avoid the first clamping hole 2501 and the second clamping hole 2521, respectively. Since the second wire 252 extends in the lateral direction of the frame 10, the second clamping holes 2521 may include at least two and spaced apart from each other, for example, there may be two or three second clamping holes 2521 in the lateral direction of the frame 10, etc. The frame 10 is provided with at least two clamping posts 112, and the first clamping hole 2501 and the second clamping hole 2521 are connected to the clamping posts 112, respectively. For ease of understanding, only the clamping column 112 located in the first cavity 101 is illustrated. In fact, similar clamping columns 112 (not shown) can also be provided in the horizontal direction of the frame 10. For example, the second clamping hole 2521 can be located in the middle of the frame 10 or close to the position corresponding to the bridge of the nose of the face after the nose pad is worn. The position of the clamping column 112 and the second clamping hole 2521 remain corresponding. It can be understood that the clamping column 112 can also be formed by the glue passing through the clamping hole 2521 during the glue filling process and then solidified. In some embodiments, the clamping column 112 can be shared, for example, the clamping column 112 can also be connected to the sealing plate 115. The first clamping hole 2501 and the second clamping hole 2521 are respectively fixed to the clamping column 112, so that the first wire 250 and the second wire 252 can be fixed, which facilitates the efficient assembly of the device 200. In addition, when the near-eye display module 100 moves relative to the frame 10, the first wire 250 is fixed by the clamping column 112 located between the first temple 220 and the near-eye display module 100. Therefore, the first wire 250 is allowed to move between the first sliding part 50 and the clamping column 112, which effectively reduces excessive movement of the first wire 250 and reduces the risk of damage to the first wire 250.

[0048] In the prior art, the structure of the temples rotating relative to the frame often opens a larger opening at the hinge, especially when the temples are unfolded or retracted. When the angle from a large angle to a small angle is larger, the opening at the hinge structure needs to be larger. Therefore, the wires are easily exposed during the rotation process. On the other hand, the pivot of such a hinge structure itself does not rotate. During the rotation process, the wires are forcibly bent at the opening, which is easy to cause damage to the wires during long-term use. In some embodiments, in combination with reference to Figure 2-7, the near-eye display device 200 may also include a rotating shaft 270, which is rotatably connected to the second limiting portion 240 and / or the first limiting portion 210, that is, the rotating shaft 270 can be allowed to rotate relative to the second limiting portion 240, the rotating shaft 270 can also be allowed to rotate relative to the first limiting portion 210, and the rotating shaft 270 can also be allowed to rotate relative to the first limiting portion 210 and the second limiting portion 240 at the same time. The rotating shaft 270 is provided with a third through hole 271, and the first through hole 201, the second through hole 241 and the third through hole 271 of the present application can also be understood as a slot or a through slot or a groove structure, which can be understood as a component that can be located or penetrated therein. 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 penetrate the third through hole 271, and 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 assembled on the second limiting portion 240 and located in the second through hole 241. The rotation of the rotating shaft 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 rotating shaft 270. For example, when the first temple 220 rotates relative to the frame 10, the rotating shaft 270 can be driven to rotate relatively. At this time, the first wire 250 and the second wire 252 are allowed to rotate synchronously themselves, rather than simply bending the first wire 250 and the second wire 252. When the first temple 220 rotates relative to the frame 10, the third through hole 271 can always be connected relative to the first temple 220 and is not easily exposed to be obviously observed by the user, which can effectively avoid the exposure of the first wire 250 and the second wire 252 during the rotation process, and reduce the risk of water or other foreign matter entering and damaging the wires. When the rotation angle is the same or larger (relative to the prior art), the present 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 can reduce the wear of the first wire 250 and the second wire 252 caused by bending or folding, effectively improving the protection of the first wire 250 and the second wire 252 during the rotation process.

[0049] In some embodiments, in combination with Figure 1-5, the near-eye display device 200 may further include a fastener 280, which may be a screw or a bolt. The first limiting portion 210 may include a first connecting section 212, which is provided with a fourth through hole 213, the second limiting portion 240 includes a second connecting section 242, which is provided with a fifth through hole 243, and the rotating shaft 270 is provided with a fixing hole 272. The fixing hole 272, the fourth through hole 213 and the fifth through hole 243 may be coaxially arranged, and the first connecting section 212 and the second connecting section 242 may be arc-shaped or annular protrusions. The fastener 280 penetrates the fourth through hole 213 and the fifth through hole 243 and is connected to the fixing hole 272. For example, one fastener 280 may be used to completely penetrate 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 242 .

[0050] In some embodiments, continue to refer to Figure 1-5 The first connection section 212 includes two oppositely arranged sections, the second connection section 242 includes two oppositely arranged sections, the fasteners 280 include two oppositely arranged sections, the second connection section 242 is located between the two first connection sections 212, the first connection section 212 and the second connection section 242 can be U-shaped or semi-I-shaped, the rotating shaft 270 is located between the two second connection sections 242, each fastener 280 is respectively connected to each second connection section 242 and each first connection section 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, and the first wire 250 and the second wire 252 are respectively spaced apart from the fasteners 280. By respectively arranging two fasteners 280 to respectively fix the first connection section 212 and the second connection section 242, the contact between the first wire 250 and the second wire 252 and the fasteners 280 can be effectively reduced, thereby reducing the wear on the wires.

[0051] In some embodiments, in combination with Figure 2-7The rotating shaft 270 may include a first rotating shaft section 2701 and a second rotating shaft section 2702. The first rotating shaft section 2701 and the second rotating shaft section 2702 may have the same structure. The first rotating shaft section 2701 and the second rotating shaft section 2702 respectively include an annular section 273, an extension section 274 and a fixing section 275.

The first rotating shaft section 2701 and the second rotating shaft section 2702 can be made of plastic, etc., and the material of the rotating shaft 270 can be different from the first limiting portion 210 and the second limiting portion 240, which can effectively reduce the material and processing costs. Of course, in other embodiments, the materials of the rotating shaft 270 , the first limiting portion 210 , and the second limiting portion 240 may also be the same, which can improve the overall firmness.

[0052] In some embodiments, in combination with Figure 2-6, the frame 10 is provided with two connecting grooves 111 arranged opposite to each other, the first position-limiting part 210 further includes a first position-limiting body 214 and a first convex part 215, the first convex part 215 and the first connecting section 212 are respectively located at the two ends of the first position-limiting body 214, the first convex part 215 extends toward the side away from the first connecting section 212, the first convex part 215 includes two interval arrangements, the two first convex parts 215 are respectively fixedly connected with the two connecting grooves 111, for example, by snapping, close fitting or bonding, etc. 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 conducive to the first convex part 215 being accurately snapped into the connecting groove 111. The two first convex parts 215 may be parallel to each other, the two first connecting sections 212 may be parallel to each other, the first convex part 215 may be parallel to the first connecting section 212, the first through hole 201 passes through the first position-limiting body 214, and the first convex part 215 and the first connecting section 212 are both located on both sides of the first through hole 201.

In some embodiments, at least one through hole 216 is provided on the first convex portion 215. The through hole 216 is used to accommodate the bonding glue, which is conducive to fully accommodating more glue, so that the first convex portion 215 is more firmly and stably connected to the connecting groove 111. It is conducive to a more stable connection between the first convex portion 215 and the connecting groove 111. In addition, the through hole 216 can also effectively reduce the overall weight of the first limiting portion 210, further reducing the weight of the device 200.

It includes a near-eye display device 200, an external terminal device 300, and an external or local cloud computing platform or server 400. The near-eye display device 200 can be firstly connected to the terminal device 300 through a wireless network such as a transceiver 2303, and the terminal device 300 is connected to the external or local cloud computing platform or server 400, thereby realizing that the near-eye display device 200 can be connected to the external or local cloud computing platform or server 400.

[0062] Combined with reference Figure 8-15 , the embodiment of the present application proposes a near-eye display module 100, which is applied to the near-eye display device 200 described in the above embodiment, and can also be applied to a part of a helmet or similar head-mounted device. The frame 10 can also be assembled to the above-mentioned device or equipment as a whole or two independent components with the near-eye display module 100. The frame 10 and the near-eye display module 100 can be movably connected, and the first shell 20 can be fixed to the frame 10 in a detachable or releasable manner. The near-eye display module 100 includes a first shell 20, a microdisplay assembly 30, a first sliding portion 50 and a damping rotation mechanism 60. The first shell 20, the first shell 20 can be made of plastic or metal, and the first shell 20 is provided with a first accommodating cavity 21. The microdisplay assembly 30 is arranged in the first accommodating cavity 21, and the microdisplay assembly 30 is used to generate light. The optical element 40 is disposed on the first housing 20 and located at the light emitting side of the micro display assembly 30. The optical element 40 can be made of materials such as PMMA (polymethylmethacrylate), PC (polycarbonate) plastic, glass, resin, etc. The light of the micro display assembly 30 enters from the first end of the optical element 40 and is emitted from the second end of the optical element 40. The first end and the second end are two opposite ends of the optical element 40. Figure 1-3 For example, the light of the microdisplay assembly 30 may be emitted from the optical axis O of the optical element 40. The light of the microdisplay assembly 30 may be emitted after being reflected multiple times in the optical element 40. In other embodiments, the light of the microdisplay assembly 30 may be emitted after being refracted and reflected in the optical element 40. After the light of the microdisplay assembly 30 is emitted from the optical element 40, digital content can be presented in the human eye.

[0063] The first sliding part 50 is located at one side of the first housing 20, and the first sliding part 50 is configured to be connected to the second sliding part 12 of the frame 10; wherein, the first sliding part 50 can be located at the side or bottom of the first housing 20, and the first sliding part 50 being located at one side of the first housing 20 can be understood as the positional relationship of the first sliding part 50 relative to the first housing 20, and the connection relationship can be that the first sliding part 50 is directly connected to the first housing 20, or the first sliding part 50 is indirectly connected to the first housing 20. One of the first sliding part 50 and the second sliding part 12 can include a protrusion, and the other can include a groove, and the two can cooperate with each other to allow the first sliding part 50 and the second sliding part 12 to slide or move relative to each other. In some embodiments, the first sliding part 50 and the second sliding part 12 can also include, for example, rolling between mutually cooperating balls or rolling between gears.

[0064] The damping rotation mechanism 60 is located between the first shell 20 and the first sliding portion 50, and the damping rotation mechanism 60 is rotatably connected to the first shell 20. The first shell 20 is configured to allow the damping rotation mechanism 60 to rotate relative to the frame 10 and maintain the optical element 40 relative to the frame 10 at an expected fixed angle to emit light; taking the frame 10 on the near-eye display device 200 as an example, the expected fixed angle of light emission can be the upper and lower directions of the eyes of the near-eye display device 200 corresponding to the wearer's eyes; it can be understood that the damping rotation mechanism 60 can be tightly connected to the first shell 20 and allow mutual rotation, and the damping rotation mechanism 60 and the first shell 20 are connected for example For example, mutual rotation can be achieved through external force, such as the user's hand or the user using a tool to operate the first shell 20 to rotate relative to the damping rotation mechanism 60. The damping rotation mechanism 60 and the first shell 20 are tightly matched with each other and have a pre-tightening force. When the first shell 20 is rotated to the angle expected by the user relative to the frame 10, the microdisplay assembly 30 and the optical element 40 are located on the first shell 20 and rotated synchronously. At the same time, the microdisplay assembly 30 and the optical element 40 follow the first shell 20 and are fixed at the expected rotation angle, so that the optical element 40 can emit light at the angle expected by the user, thereby achieving the light output angle adjustment that meets the user's expectations.

[0065] The first sliding portion 50 is configured to allow movement relative to the second sliding portion 12, and drives the damping rotation mechanism 60 and the first shell 20 to move synchronously relative to the frame 10, and keeps the optical element 40 at an expected fixed lateral position relative to the frame 10. The lateral position may be the extension direction of the first sliding portion 50 or the second sliding portion 12. Taking the frame 10 on the near-eye display device 200 as an example, the lateral position may be the direction of the left and right eyes of the near-eye display device 200 corresponding to the user wearing the device. It can be understood that mutual movement or sliding can be achieved through external force, for example, the user's hand or the user uses a tool to operate the first shell 20 to move horizontally, and the first sliding part 50 moves relative to the second sliding part 12 of the frame 10, thereby driving the damping rotation mechanism 60 connected to the first shell 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 shell 20 and moved synchronously, and the first sliding part 50 and the second sliding part 12 can maintain a close fit. At the same time, the microdisplay assembly 30 and the optical element 40 follow the first shell 20 and remain fixed in the expected lateral position. The lateral position can be the rotation center A of the shaft of the damping rotation mechanism 60, or it can be the extension direction of the first sliding part 50, so that the optical element 40 can emit light at the lateral position expected to move by the user, thereby achieving the lateral light emission position adjustment that meets the user's expectations.

[0066] The above method can achieve the lateral field of view angle adjustment of the optical element 40 through the first sliding part and the second sliding part, and the vertical field of view angle adjustment of the optical element 40 through the damping rotation mechanism 60 after the near-eye display module 100 is assembled to the frame 10 of the near-eye display device 200, or when the near-eye display module 100 is worn on the human eye, so as to meet the needs of different users to have clear viewing within their respective fields of view. At the same time, the movement of the first sliding part 50 drives the damping rotation mechanism 60, the first shell 20, the microdisplay assembly 30 and the optical element 40 to move synchronously relative to the frame 10, effectively improving the stability of the overall components during movement, and at the same time ensuring that the damping rotation mechanism 60 can rotate at each lateral position during movement, effectively improving the accuracy of the field of view angle adjustment.

[0067] In some embodiments, the first shell 20 is further provided with a scale mark on the side 102 facing the human eye. When the user operates the near-eye display module 100 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. Figure 1 and 9The frame 10 may further include an upper frame 13 and a lower frame 14, the lens 105 may be installed between the upper frame 13 and the lower frame 14, the upper frame 13 may be away from the lens 105, the rotation range of the first shell 20 toward the lens 105 is greater than the rotation range toward the upper frame 13, it can be understood that the angle at which the first shell 20 is allowed to rotate toward the lens 105 or the lower frame 14 is greater than the rotation angle toward the upper frame 13, combined with Fig.13 For example, after the near-eye display module 100 is assembled to the frame 10, with S1 as a reference, the angle of rotation of the near-eye display module 100 toward the S2 direction (right side) is greater than the angle of rotation toward the side away from the S2 direction (left side), thereby facilitating the user to efficiently adjust to a suitable vertical viewing angle.

[0068] In some embodiments, in conjunction with Fig. 9 and 14 , the rotation center A of the rotating shaft of the damping rotation mechanism 60 is parallel to the plane where the microdisplay assembly 30 is located. It can be understood that the entire microdisplay assembly 30 or the main part thereof can be in the shape of a plate. For example, the microdisplay 31 of the microdisplay assembly 30 can be in the shape of a plane or a plate. Then, the plane itself or the plane where it is located can be used as a reference. The direction of the rotation center A can also be described as horizontal in some embodiments. The rotation center A of the rotating shaft of the damping rotation mechanism 60 is parallel to the plane where the microdisplay assembly 30 is located, thereby ensuring that the entire microdisplay assembly 30 or the main part of the microdisplay assembly 30 (i.e., the microdisplay 31) remains relatively fixed during rotation, thereby reducing the risk of position 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, which effectively reduces the width effect caused by the first sliding portion 50 being located beside the first housing 20. Therefore, when the near-eye display module 100 is assembled to the frame 10, for example, after being assembled to the frame 10 on the near-eye display device 200, the width of the frame 10 can be effectively reduced, which is beneficial to the hidden design of the near-eye display module 100. The first sliding portion 50 extends along the direction of the rotation center A of the rotating shaft of the damping rotation mechanism 60, and the extension length of the first sliding portion 50 is less than the length of the micro display assembly 30, which effectively reduces the material and weight of the first sliding portion 50, and further effectively reduces the weight of the near-eye display module 100, which is beneficial to the lightweight of the near-eye display module 100 after being assembled to the frame 10.

[0069] In some embodiments, in conjunction with Figure 12-14, a first hole 22 is provided on the first shell 20, and the damping rotation mechanism 60 includes a locking member 61 and a sleeve 62. The central axial line connecting the locking member 61 and the first hole 22 is the direction of the rotation center A. The rotating shaft of the damping rotation mechanism 60 can be located on the locking member 61, and the locking member 61 is fixed to the first hole 22 through the sleeve 62. The locking member 61 can be a screw, a bolt or a bolt. The locking member 61 can be provided with an external thread, and the inner wall of the first hole 22 can be provided with an internal thread, and 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 interference fit, for example, the shaft of the locking member 61 is inserted into the first hole 22 to produce elastic deformation to achieve 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 arranged on its mating surface to achieve damping rotation. In other embodiments, the locking member 61 and the first hole 22 are connected by key connection or adhesive connection to achieve damping rotation. The first sliding portion 50 is connected to the outer periphery of the sleeve 62, and the first sliding portion 50 extends in a direction away from the locking member 61. It can be understood that by connecting the first sliding portion 50 and the locking member 61 together, the first sliding portion 50 can drive the entire damping rotation mechanism 60 to move in the direction (or transversely) of the rotation center A. At the same time, when the first sliding portion 50 and the second sliding portion 12 are connected, the first sliding portion 50 is circumferentially fixedly supported, thereby allowing the first shell 20 to rotate relative to the frame 10 through the damping rotation mechanism 60. For example, the user can operate the first shell 20 by hand or an external clamp to realize the rotation of the first shell 20, thereby driving the synchronous rotation of the optical element 40 to achieve the expected fixed angle light output adjustment.

[0070] In some embodiments, continue to refer to Fig.12 The damping rotation mechanism 60 may further include a first gasket 63 and a second gasket 64, the locking member 61 passes through the shaft sleeve 62, the first gasket 63 and the second gasket 64 and is fixed to the first hole 22; wherein the first gasket 63 and the second gasket 64 may be made of rubber, plastic, metal or composite materials, etc., the two gaskets can ensure that the locking member 61 and the first hole 22 are fixed more firmly, effectively improve the damping effect during the rotation process, and reduce the damping rotation mechanism 60 being too loose during rotation, causing the first shell 20 to be unable to maintain the expected fixed rotation position, that is, when the user rotates the first shell 20 to the expected angle, relying on this damping force, the first shell 20 can still maintain the position of the angle, and finally ensure that the optical element 40 emits light at the expected stable angle.

[0071] In some embodiments, Fig.12The first gasket 63 and the second gasket 64 are respectively located on both sides of the sleeve 62, that is, the sleeve 62 is clamped by the first gasket 63 and the second gasket 64, the locking member 61 can have a threaded shaft portion 611 and a head 612 such as a straight or cross, the first gasket 63, the second gasket 64 and the sleeve 62 can be sleeved on the shaft portion 611, and the shaft portion 611 is fixed to the first hole 22 by rotating the head 612, one of the gaskets can be located between the head 612 of the locking member 61 and the sleeve 62, and the other gasket can be located between the sleeve 62 and the first shell 20.

[0072] In other embodiments, the first gasket 63 and the second gasket 64 are both located on the same side of the sleeve 62, the first gasket 63, the second gasket 64 and the sleeve 62 are sleeved on the shaft portion 611, the first gasket 63 and the second gasket 64 are both located between the head portion 612 and the sleeve 62, or the first gasket 63 and the second gasket 64 are both located between the first shell 20 and the sleeve 62.

[0073] 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, and the protrusion 24 may be cylindrical, and the protrusion 24 is provided with a first hole 22 having a thread, and the sleeve 62 is at least partially sleeved on the protrusion 24. It can be understood that the protrusion 24 can effectively reduce the length of the shaft portion 611 of the locking member 61, and the sleeve 62 can be sleeved on the protrusion 24 and pressed and fixed to the first hole 2 by the head 612 of the locking member 61. 2; in other embodiments, the sleeve 62 may be partially sleeved on the protrusion 24 and partially sleeved on the shaft portion 611 to be fixed in the first hole 22. In other embodiments, for the first gasket 63 and the second gasket 64, the first gasket 63, the second gasket 64 and the sleeve 62 may all be sleeved on the protrusion 24, or part of the first gasket 63, the second gasket 64 and the sleeve 62 may be sleeved on the protrusion 24 and the other part may be sleeved on the shaft portion 611. The extension length of the first sliding portion 50 is less than the radial dimension of the optical element 40, so that the length of the first sliding portion 50 can be effectively reduced, thereby reducing the overall weight.

[0074] In some embodiments, in combination Figure 9-12The microdisplay assembly 30 includes a microdisplay 31, a first wire 32 and a first electrical interface 33 that are electrically connected to each other. The microdisplay 31 is aligned with the optical element 40, wherein 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), etc., or any combination of these technologies. The first wire 32 is connected between the micro display 31 and the first electrical interface 33, and the first wire 32 can be a flexible electrical board; the damping rotation mechanism 60 and the first sliding part 50 are both located on the side of the first shell 20 close to the micro display 31 and away from the first electrical interface 33, so as to avoid the position interference between the first sliding part 50 and the first electrical interface 33 during the movement and rotation process, which is conducive to the assembly of the near-eye display module 100 to the frame 10 and facilitates the rotation and movement of the display module 100. Fig. 9 and 12The micro display 31 and the first wire 32 are electrically connected to the second electrical interface 2510 through the first electrical interface 34, wherein the second electrical interface 2510 may be located in the first cavity 101 of the frame 10, and the second electrical interface 2510 may be further electrically connected to the first electrical device 230 (e.g., processor 2301) located on the first temple 220 through the first wire 250. In some embodiments, a reinforcing plate or a cache chip 34 may be further provided on the back of the first electrical interface 34. Among them, the microdisplay 31, the first wire 32 and the first electrical interface 34 can be sealed and connected to the first shell 20. For example, the first shell 20 can also be provided with a cover plate 26, and the cover plate 26 is sealed and connected to the first shell 20, so as to seal the microdisplay 31 and the first wire 32 in the first accommodating cavity 21. Of course, an opening can also be set at the position of the cover plate 26 corresponding to the first electrical interface 34, so as to allow the first electrical interface 34 and the second electrical interface 2510 to be electrically connected; in other embodiments, the cover plate 26 may also be not provided. After the first electrical interface 34 and the second electrical interface 2510 are electrically connected, the microdisplay 31, the first wire 32, the first electrical interface 34 and the second electrical interface 2510 are sealed with glue by means of glue filling and sealing. By sealing the microdisplay 31, the first wire 32 and the first electrical interface 34 to the first shell 20, the waterproof effect of the display module 20 can be effectively improved, and the risk of sweat or rainwater infiltration during wearing can be reduced. In some embodiments, the extension length of the first sliding portion 50 may be smaller than the length of the micro display 31 , thereby reducing the size of the first sliding portion 50 and lowering the overall weight.

[0075] Combined with reference Fig.14 The sleeve 60 may include an annular body 621 and a second hole 623 in the annular body 621, and the shaft portion 611 is provided with 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 621, for example, it may be tangent to the annular body 621, and the outer edge portion 54 is connected to the connecting portion 52, and 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 621, and the second sliding portion 12 may include a groove that matches 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, so as to achieve position fixation during the sliding process.

[0076] In some embodiments, in conjunction with Figure 10-13, the near-eye display module 100 also includes a first center plane S1 passing through the rotation center A of the rotating shaft of the damping rotation mechanism 60 and passing through the frame 10. For example, the frame 10 of the first shell 20 has a bottom plane, and the first center plane S1 is perpendicular to the plane, or the first center plane S1 can be a symmetrical center plane of the frame 10. For example, the second sliding portion 12 can include grooves on both sides, and the grooves on both sides are symmetrical relative to the first center plane S1. The optical element 40 includes a second center plane S2, and the overall structure of the optical element 40 can be symmetrical relative to the second center plane S2. In some embodiments, the second center plane S2 can also be the center of the first shell 20, and the second center plane S2 can also be a plane passing through the optical axis O. It can be understood that the introduction of the above center plane is only for the convenience of describing the relative rotation relationship between the optical element 40 and the frame 10. In other embodiments, if other reference systems (such as reference planes or reference centers) are cited to directly or indirectly describe the relative rotation relationship between the optical element 40 and the frame 10, it 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 the user can change it according to actual needs. Figure 2 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 plates, the frame 10 and the first housing 20 are parallel to each other, or the optical element 40 and the frame 10 are parallel. Figure 8 This is an exemplary diagram of the first housing 20 driving the optical element 40 to rotate to the second position, wherein the rotation angle C of the second center plane S2 relative to the first center plane S1 is not 0°.

[0077] In some embodiments, in combination with reference Figure 1-11 , the moving distance of the first shell 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 the user can change it according to actual needs. Since the micro display 31 and the optical element 40 are arranged on the first shell 20, the micro display 31 and the optical element 40 are driven by the first shell 20 to move synchronously, so as to realize the lateral light emission at different positions. Figure 2 As shown, this position can be understood as the initial position, and the moving distance is 0cm. Figure 3 is an example diagram showing that the moving distance of the first shell 20 relative to the frame 10 is greater than 0 cm, wherein Figure 3It is also illustrated that the first housing 20 drives the optical element 40 of the first housing 10 to rotate at an angle greater than 0°. It can be understood that the movement operation and the rotation operation of the near-eye display module 100 of the present application can be performed separately, and rotation during the movement process or movement during the rotation process can be allowed. The damping rotation mechanism 60 can be allowed to be moved as a whole in the lateral position, effectively improving the flexibility and accuracy of the light output angle of the near-eye display module 100, while effectively reducing interference and damage to the device during movement and operation.

[0078] In some embodiments, in conjunction with Fig.15 The optical element 40 further includes a light-incoming surface 42, a first reflecting surface 43, a second reflecting surface 44 and a light-emitting surface 45; the light-incoming surface 42 is located at the first end; the first reflecting surface 43 is located at the second end opposite to the first end; the second reflecting surface 44 is located at the first end, and the second reflecting surface 44 surrounds the light-incoming surface 42;

[0079] The light emitting surface 45 is located at the second end, the light emitting surface 45 surrounds the first reflecting surface 43, the micro display assembly 30 faces the light inlet surface 42, and the second optical element 60 faces the light emitting surface 45; wherein the optical element 40 can be a solid substrate structure made of a transparent or light-transmitting material, the light inlet surface 42 and the second reflecting surface 44 are located at the first end of the solid substrate, and the first reflecting surface 43 and the light emitting surface 45 are located at the second end of the solid substrate. In some embodiments, the optical element 40 can be a hollow structure, for example, there is a hollow structure between the first end and the second end. It can be understood that the first reflecting surface 43 and the second reflecting surface 44 are coated with a reflective film, such as a metal or metal alloy reflective film such as silver or aluminum. The microdisplay 30 faces the light incident surface 42, and the second optical element 60 faces the light emitting surface 45. The light generated by the microdisplay 31 enters from the light incident surface 42 and is projected onto the first reflective surface 43, then reflected from the first reflective surface 43 to the second reflective surface 44, and finally emitted from the light emitting surface 45, wherein the first reflective surface 43 and the second reflective surface 44 may include one or a combination of inclined planes, curved surfaces, spherical surfaces, aspherical surfaces or free-form surfaces, and the incident surface 43 and the exit surface 46 may be one or a combination of planes, curved surfaces, spherical surfaces, aspherical surfaces or free-form surfaces.

[0080] In some embodiments, the first reflection surface 43 and the light-emitting surface 45 can be continuous surfaces, and the light-incoming surface 42 and the second reflection surface 44 can be continuous surfaces. The continuous surfaces can be understood as being constructed by the same function, for example, they are all free-form surfaces constructed using the same Zernike polynomial function. In some embodiments, the surface formed by the first reflection surface 43 and the light-emitting surface 45, and the surface formed by the light-incoming surface 42 and the second reflection surface 44 are constructed by the same function, and the two can be parallel to each other. In some embodiments, the surface formed by the first reflection surface 43 and the light-emitting surface 45, and the surface formed by the light-incoming surface 42 and the second reflection surface 44 are all free-form surfaces.

[0081] In some embodiments, the light-incoming surface 42 and the first reflecting surface 43 may both be circular, elliptical, or polygonal, etc., and the shapes of the second reflecting surface 44 and the light-emitting surface 45 may be polygonal, circular, elliptical, a closed shape formed by arcs + straight edges, etc. In some embodiments, the light-incoming surface 42 and the first reflecting surface 43 are the same or similar. In some embodiments, the area of ​​the first reflecting surface 43 is greater than or equal to 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 fully enter and be fully reflected and then emitted from the light-emitting surface 45.

[0082] In some application scenarios, the optical element 40 may be cylindrical in shape, such as a cylinder or an elliptical cylinder. When assembling a product, it is often difficult to distinguish the exact orientation of the optical element 40, resulting in assembly errors. Fig.10 In the present application, a chamfer 421 is provided on the periphery of the light-incoming surface 42, and the chamfer 421 can be a straight edge, a prism, a triangle or a polygon, etc. 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, the intersection of H3 and H5 is the center R2 of the second reflecting surface 44, the light-incoming surface 42 is eccentrically arranged relative to the second reflecting surface 44, and the center of gravity R1 of the light-incoming surface 42 is eccentrically arranged with a preset distance relative to the center R2 of the second reflecting surface 44, and the eccentric distance can be 0.1 mm, 0.15 mm, 0.2 mm, etc. The straight-edge chamfer 421 and / or eccentric setting are helpful for identifying the position and orientation of the optical element 40, that is, identifying the orientation of the positive projection surface of the optical element 40, for example, the first end or the second end of the optical element 40 can be identified; or it can be identified that the optical element 40 is rotated, for example, the assembly process uses machine vision to locate the optical element 40 or detect and identify the orientation, etc., which is beneficial to the positioning and installation of the optical module 42 relative to the microdisplay 31, making the overall assembly more accurate.

[0083] In some embodiments, the light-inlet surface 42, the first reflective surface 43, the second reflective surface 44 and the light-emitting surface 45 include free-form surfaces and are generated by the same continuous function, that is, the mold or mask material can be shared, effectively reducing the production and manufacturing cost of the optical element 40. The outer contour of the projection area of ​​the optical element 40 relative to the micro-display assembly 30 includes a circle or an ellipse. It can be understood that in some embodiments, the light-inlet surface 42 and the first reflective surface 43 can be elliptical; or, the light-emitting surface 45 can also be elliptical, wherein the long side of the ellipse can correspond to the horizontal field of view of the human eye, and the short side can correspond to the vertical field of view of the human eye. Considering that the horizontal field of view of the human eye is greater than the vertical field of view, the outer contour is designed to be elliptical to more easily meet the viewing requirements of the field of view of the human eye.

[0084] For other designs or structures of the optical element 40 , reference may also be made to the descriptions of related embodiments in prior Chinese application numbers 2023111912240, 2024205421010, 2023115809662 or 2023115822046.

[0085] In some embodiments, in conjunction with Figure 9-12 , the near-eye display module 100 may also include a sleeve 46, the first housing 20 is further provided with a flange 22, the optical element 40 is located in the sleeve 46, and the sleeve 46 is configured to allow the relative flange 22 to be movably connected and adjust the distance of the optical element 40 relative to the microdisplay assembly 30. It is understood that the sleeve 46 may be provided with an internal thread 462, and the flange 22 may be provided with an external thread, and the two are mutually threadedly connected to achieve the distance adjustment of the optical element 40 relative to the microdisplay 31. In other embodiments, the sleeve 46 is configured to be releasably connected to the flange 22, and the releasability may be to provide one or more of various mechanisms to fix the components to each other. For example, a mechanism such as a lock, a latch, a snap, a slide, a channel, a screw, a buckle, a thread, a magnet, a pin, an interference (e.g., friction) fit, a roller, a bayonet, a fused material, a fabric, a knitted fabric, a braid, a hook-and-loop fastener, and / or a combination thereof may be included to couple the sleeve 46 and / or fix the first housing 20 together. The sleeve 46 and the first housing 20 can remain fixed to each other until an optional release mechanism is actuated, such as by a user's active operation such as squeezing, pressing, rotating, sleeved, snapping or buckling. In some embodiments, there is a space between the first housing 20 and the sleeve 46, such as Figure 1 , 3 The optical element 40 can present digital contents of different clarity at different positions relative to the micro display 31, and people with different vision can adjust the distance of the optical element 40 according to their own vision defects.

[0086] In some embodiments, Fig. 9, a second optical element 60 may also be provided on the sleeve 46, and the second optical element may be fixed to the sleeve 46 by means of snap-on, adhesive or threaded connection. The second optical element is located on the light-exiting side of the optical element 40, and the second optical element is configured to provide the desired vision correction, and the correction of the second optical element may be spherical, aspherical, toroidal, cylindrical, single-vision, multifocal, progressive, and / or adjustable, such as correction for specific eyes or vision-impaired people such as myopia, hyperopia, color blindness, etc. Various correction combinations of the second optical element may be provided with different lenses or eyeglasses. For example, each of any given lens or eyeglass may have a known correction parameter type based on the identification of the design. Corresponding identifiers such as those based on product inventory may be assigned for reference and facilitate selection for users with different vision. In some embodiments, the second optical element may include a concave lens, a convex lens, a convex cylindrical lens or a convex cylindrical lens with different refractive powers, and the second optical element may correct the vision of the light projected from the optical element 40 so that the user with visual impairment can clearly see the image content from the micro display 30. In other embodiments, the first housing 20 and the sleeve 46 may be separated separately, wherein the second optical element 60 may remain fixed on the sleeve 46, thereby the sleeve 46 containing different vision correction second optical elements may be replaced according to the users with different vision.

[0087] In some embodiments, the second optical element 60 can provide the expected optical effect or optical crosstalk, for example, the second optical element can include one or more attenuation plates, diffusers, filters, polarizers, prisms, beam splitters, diffraction gratings, reflectors and / or windows. In some embodiments, for users without visual impairment, no correction is required, and the second optical element can be a plano lens or a zero-degree lens without diopter, which only provides a protective function for the optical element 40 and reduces the wear and tear on the optical element 40.

[0088] 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 46 is configured to be releasably connected to the first shell 20, allowing different users to replace different second optical elements 60 according to their own vision needs, so that users with user defects can still see the digital content from the microdisplay 30 in full and clearly.

[0089] In some embodiments, the projection area of ​​the second optical element 60 in the first direction A may be 15 mm 2 -45 mm 2 (square millimeters), for example 15mm 2 、17mm 2 、19mm 2 , 20mm2 、36mm 2 , 40mm 2 , 45mm 2 The projection area of ​​the first optical element 40 in the first direction A is 10 mm 2 -20mm 2 , for example 10mm 2 , 12mm 2 , 14mm 2 、17mm 2 、19mm 2 , 20mm 2 It can be understood that the projection area of ​​the second optical element needs to always be greater than or equal to the projection area of ​​the first optical element 40.

[0090] In some embodiments, the projection area of ​​the first housing 20 and the sleeve 46 in the first direction A is not greater than 60 mm. 2 It can be understood that, for example, the projection area of ​​the first shell 20 and the sleeve 46 can be 50mm 2 、54mm 2 , 55mm 2 、60mm 2 In some embodiments, for example Figure 1-3 , the projection area of ​​the sleeve 46 in the first direction A is larger than the projection area of ​​the second shell 20; in other embodiments, for example Figure 6-9 As shown, the projection area of ​​the sleeve 46 in the first direction A is larger than the projection area of ​​the first optical element 40 but smaller than the projection area of ​​the first shell 20. The projection areas of the first shell 20 and the sleeve 46 are smaller, so they have smaller volume and weight, which is convenient for matching with the near-eye display device 100. Compared with existing near-eye devices such as AR or VR, the overall volume and weight of the module and device of the present application are lighter, which is conducive to users wearing for a long time, and can be cleverly integrated with existing myopia glasses, hyperopia glasses, sunglasses, protective glasses or smart glasses, which is not easy to cause excessive weight and size, and is not too abrupt in appearance, nor will it affect the user's normal field of vision.

[0091] Since the first shell 20, the sleeve 46, the first optical element 40 and the second optical element 60 can be circular, elliptical or other various shapes. In some embodiments, the material of the first shell 20 and the material of the sleeve 46 are at least partially different, for example, the hardness (rigidity) of the first shell 20 is greater than the hardness (rigidity) of the sleeve 46, the first shell 20 can be made of metal, plastic, etc., the sleeve 46 can be made of elastic or flexible material, such as silicone, rubber or elastic plastic, and the first shell 20 and the sleeve 46 are configured to be elastically connected. In other embodiments, the hardness of part of the first shell 20 can also be greater than the hardness of part of the sleeve 46, and the part can be a part of the structure where the two are in contact with each other. The first shell 20 and the sleeve 46 may be elastically sleeved; in other embodiments, the first shell 20 and the sleeve 46 may also be elastically clamped, that is, the sleeve 46 clamps the first shell 20, causing the first shell 20 or the sleeve 46 to at least partially deform or elastically deform; or when the two are threadedly connected, the first shell 20 or the sleeve 46 at least partially deforms or elastically deforms. In other embodiments, for example, an elastic ring (or a silicone ring, etc.) may be located in the gap of the clamping or threaded connection, or the end of the sleeve 46 may abut against a soft plate (or an elastic plate or a silicone plate). Therefore, different users may use different lenses or second optical elements according to their needs, and / or not use the second optical element 60 including a lens or a lens.

[0092] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
