[0095] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the protection scope of this disclosure.

[0096] It should be noted that, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be enlarged in the accompanying drawings. Therefore, the dimensions and relative dimensions of the individual components are not necessarily limited to those shown in the drawings. In the specification and accompanying drawings, the same or similar reference numerals indicate the same or similar parts.

[0097] When an element is described as being "on" another element, "connected to" another element, or "attached to" another element, the element may be directly on, directly connected to, or directly attached to the other element, or there may be intermediate elements. However, when an element is described as being "directly on" another element, "directly connected to" another element, or "directly attached to" another element, there are no intermediate elements. Other terms and / or expressions used to describe relationships between elements should be interpreted in a similar manner, such as "between" versus "directly between," "adjacent" versus "directly adjacent," or "on" versus "directly on," etc. Furthermore, the term "connection" can refer to a physical connection, an electrical connection, a communication connection, and / or a fluid connection. Moreover, the X-axis, Y-axis, and Z-axis are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the X-axis, Y-axis, and Z-axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purposes of this disclosure, “at least one of X, Y, and Z” and “at least one selected from the group consisting of X, Y, and Z” can be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z such as XYZ, XY, YZ, and XZ. As used herein, the term “and / or” includes any and all combinations of one or more of the listed related items.

[0098] It should be noted that although the terms "first," "second," etc., may be used herein to describe various components, members, elements, regions, layers, and / or parts, these components, members, elements, regions, layers, and / or parts should not be limited by these terms. Rather, these terms are used to distinguish one component, member, element, region, layer, and / or part from another. Thus, for example, the first component, first member, first element, first region, first layer, and / or first part discussed below may be referred to as a second component, second member, second element, second region, second layer, and / or second part without departing from the teachings of this disclosure.

[0099] For ease of description, spatial relation terms, such as “above,” “below,” “left,” “right,” etc., may be used herein to describe the relationship between one element or feature and another element or feature as shown in the figure. It should be understood that spatial relation terms are intended to cover other orientations of the device in use or operation besides those described in the figure. For example, if the device in the figure were inverted, an element described as “below” or “under” other elements or features would be oriented “above” or “on top” other elements or features.

[0100] In this document, the terms “substantially,” “approximately,” “approximately,” “roughly,” and other similar terms are used as terms of approximation rather than as terms of degree, and they are intended to account for inherent deviations in measured or calculated values ​​that would be recognized by one of ordinary skill in the art. Taking into account factors such as process variations, measurement problems, and errors associated with the measurement of a particular quantity (i.e., limitations of the measurement system), “approximately” as used herein includes stated values ​​and indicates that a particular value is within an acceptable range of deviation for one of ordinary skill in the art. For example, “approximately” may mean within one or more standard deviations, or within ±30%, ±20%, ±10%, ±5% of the stated value.

[0114] According to some exemplary embodiments, referring to Figures 4, 8-11, the temple connector 52 includes a clamping member 521, which is configured to apply an inward rebound force relative to the main housing 10 to the temple assembly 51 after it is folded outward relative to the main housing 10. The rebound force applied by the clamping member 521 can effectively prevent the glasses from moving or falling off the user's face during wear, ensuring the stability of the glasses.

[0115] Figure 12 schematically shows an exploded view of a clamping member in eyeglasses according to some embodiments of the present disclosure. Figure 13 schematically shows a perspective view of a clamping member in eyeglasses according to some embodiments of the present disclosure. Figure 14 schematically shows a schematic diagram of the limiting principle of a clamping member in eyeglasses according to some embodiments of the present disclosure.

[0116] According to some exemplary embodiments, referring to Figures 12 and 13, the clamping member 521 includes a first rotating shaft 5211, a torsion spring portion 5212, a first clamping portion 5213, a second clamping portion 5214, a bushing 5215, and a retaining ring 5216. The first clamping portion 5213 and the second clamping portion 5214 can be sheet metal parts. The first clamping portion 5213 includes a third sub-part 5213b and two first sub-parts 5213a. The two first sub-parts 5213a are spaced apart along the axial direction of the first rotating shaft 5211. The third sub-part 5213b is connected between the two first sub-parts 5213a. The two first sub-parts 5213a are respectively provided with a first rotating hole 52131. The second clamping part 5214 includes a fourth sub-part 5214b and two second sub-parts 5214a. The two second sub-parts 5214a are spaced apart along the axial direction of the first rotating shaft 5211. The fourth sub-part 5214b is connected between the two second sub-parts 5214a. Each of the two second sub-parts 5214a has a second rotating hole 52141. The torsion spring part 5212 includes a torsion spring body 52121 and a first torsion foot 52122 and a second torsion foot 52123 connected to both ends of the torsion spring body 52121.

[0117] The torsion spring portion 5212 is located between the two first sub-parts 5213a of the first clamping portion 5213. The hole of the torsion spring body 52121 is aligned and assembled with the first rotating hole 52131 in the first sub-part 5213a. The second rotating hole 52141 on the second sub-part 5214a of the second clamping portion 5214 is aligned and assembled with the first rotating hole 52131. The first torsion foot 52122 of the torsion spring portion 5212 is fixed on the third sub-part 5213b, and the second torsion foot 52123 of the torsion spring portion 5212 is fixed on the fourth sub-part 5214b. The bushing 5215 passes through the first rotating hole 52131, the second rotating hole 52141, and the hole of the torsion spring body 52121, and the first rotating shaft 5211 passes through the bushing 5215. The first rotating shaft 5211 has a groove 52111 on one side, and the snap ring 5216 is fixed in the groove 52111 to fix the entire clamping member 521.

[0118] According to some exemplary embodiments, referring to Figures 8, 9, 10, and 13, the first clamping portion 5213 further includes a fifth sub-portion 5213c and a sixth sub-portion 5213d, which are respectively connected to two first sub-portions 5213a. The fifth sub-portion 5213c and the connected first sub-portion 5213a are perpendicularly connected, and the sixth sub-portion 5213d and the connected first sub-portion 5213a are also perpendicularly connected. The holes in the fifth sub-portion 5213c and the sixth sub-portion 5213d are respectively installed on the positioning posts of the second housing 12 for positioning, and then tightened with screws to fix the first clamping portion 5213 to the main housing 10.

[0119] The temple connector 52 also includes a rotating member 522. Holes in the fourth sub-part 5214b are respectively installed on the positioning posts of the rotating member 522 for positioning, and then tightened with screws to fix the second clamping part 5214 to the rotating member 522. A rotating hole is provided on the side of the rotating member 522 away from the clamping part 521, and a rotating hole is provided on the side of the temple inner shell 511 near the rotating member 522. The second rotating shaft 5221 passes through the rotating holes of the temple connector 52 and the temple inner shell 511, and is then locked with a hot-melt copper nut built into the rotating hole on the top side of the temple inner shell 511, so that the rotating member 522 is rotatably connected to the temple inner shell 511. To enhance aesthetics, two CD-patterned decorative metal pieces 5222 can be used to block the two rotating holes on the top and bottom sides of the temple inner shell 511. The completed structure is shown in Figure 11.

[0120] After the temple assembly 51 is folded outward relative to the main housing 10, the rotating member 522 drives the second clamping part 5214 to also rotate outward to a certain extent relative to the main housing 10. The second clamping part 5214 further drives the torsion spring part 5212 to undergo torsional deformation. The torque generated by the torsion spring part 5212 can apply an inward rebound force to the temple assembly 51 relative to the main housing 10.

[0121] According to some exemplary embodiments, referring to Figures 12, 13 and 14, a first sub-part 5213a of the first clamping part 5213 and a second sub-part 5214a of the second clamping part 5214 are arranged adjacent to each other along the axial direction of the first rotation axis 5211, and another first sub-part 5213a of the first clamping part 5213 and another second sub-part 5214a of the second clamping part 5214 are arranged adjacent to each other along the axial direction of the first rotation axis 5211. Along the axial direction of the first rotation axis 5211, a set of adjacent first sub-parts 5213a and second sub-parts 5214a and another set of adjacent first sub-parts 5213a and second sub-parts 5214a are respectively located on both sides of the torsion spring portion 5212. In at least one set of first sub-parts 5213a and second sub-parts 5214a, one of the first sub-parts 5213a and second sub-parts 5214a is provided with a limiting groove 521a, and the other of the first sub-parts 5213a and second sub-parts 5214a is provided with a limiting protrusion 521b, for example... The first sub-part 5213a is provided with a limiting groove 521a, and the second sub-part 5214a is provided with a limiting protrusion 521b. The limiting protrusion 521b is located in the limiting groove 521a. The limiting protrusion 521b and the limiting groove 521a are spaced apart on at least one side along the rotation direction of the first rotating axis 5211. Through the limiting cooperation between the limiting groove 521a and the limiting protrusion 521b, the temple assembly can continue to rotate outward by a predetermined angle α to the maximum opening state when it is in the naturally open state. For example, the predetermined angle can be 15°.

[0122] For example, each of the two first sub-parts 5213a has a limiting groove 521a, and each of the two second sub-parts 5214a has a limiting protrusion 521b. Along the extending direction of the first rotation axis 5211, the two first sub-parts 5213a are located outside the two second sub-parts 5214a. In any one of the second sub-parts 5214a, the limiting protrusion 521b of the second sub-part 5214a protrudes away from the other second sub-part 5214a, thereby being located within the limiting groove 521a of the adjacent first sub-part 5213a.

[0123] Referring to Figures 13 and 14, in the naturally open state of the temples, the sidewalls of the limiting protrusion 521b and the limiting groove 521a located on the outer side of the limiting protrusion 521b (the side away from the optical engine) are spaced apart (i.e., the state shown in Figure 13). During the wearing process, the user can continue to flip the temple assembly outward as needed. After further flipping by a predetermined angle α, the sidewalls of the limiting protrusion 521b and the limiting groove 521a located on the outer side of the limiting protrusion 521b abut against each other, thereby restricting the second clamping part 5214 from continuing to rotate relative to the first clamping part 5213, thereby limiting the maximum open state of the temple assembly.

[0124] According to some exemplary embodiments, referring to Figures 3 and 5, the temple assembly 51 further includes a temple housing 512 and a temple decorative element 515. The temple decorative element 515 is engaged and fixed with the rotating element 522 by a snap fastener, and the temple housing 512 is engaged and fixed with the temple inner housing 511 by a snap fastener.

[0125] According to some exemplary embodiments, referring to Figures 8 and 11, the temple assembly 51 also includes a foam pad 514, which is attached to a groove in the inner shell 511 of the temple by double-sided adhesive.

[0126] According to some exemplary embodiments, referring to Figures 8 and 9, the glasses also include a proximity sensor 61, which is disposed between two first mounting holes corresponding to the user's forehead position, and is used to detect the user's forehead position. The proximity sensor 61 is fixed to the third mounting hole 123 of the second housing 12 by screws, and the glass cover 123a is attached to the third mounting hole 123.

[0127] Figure 15 schematically shows an exploded cross-sectional view of the optical mechanism in eyeglasses according to some embodiments of the present disclosure. Figure 16 schematically shows an exploded perspective view of the optical mechanism in eyeglasses according to some embodiments of the present disclosure.

[0128] According to some exemplary embodiments, referring to Figures 15 and 16, the optical engine 20 includes an upper lens barrel assembly 21, a lower lens barrel assembly 22, a display module 23, and a module back plate 24. The upper lens barrel assembly 21, the lower lens barrel assembly 22, the display module 23, and the module back plate 24 are assembled sequentially along the first direction D1 to obtain the optical engine 20.

[0129] The upper lens barrel assembly 21 includes an upper lens barrel housing 211 and at least one lens disposed within the upper lens barrel housing 211. For example, it includes a first lens 212, a second lens 213, and a third lens 214 arranged sequentially along a first direction D1. The first lens 212 and the third lens 214 are convex lenses, and the second lens 213 is a concave lens. The lens skirts of the first lens 212, the second lens 213, and the third lens 214 are pre-fixed to the bosses inside the upper lens barrel housing 211, and then fixed with adhesive along the gap between the lens and the inner wall of the upper lens barrel housing 211.

[0130] The lower lens barrel assembly 22 includes a lower lens barrel housing 221 and at least one lens disposed within the lower lens barrel housing 221, such as a fourth lens 222 and a fifth lens 223 sequentially disposed along a first direction D1, wherein the fourth lens 222 is a convex lens and the fifth lens 223 is a concave lens. The lens skirts of the fourth lens 222 and the fifth lens 223 are pre-fixed to a boss within the lower lens barrel housing 221, and then fixed with adhesive along the gap between the lens and the inner wall of the lower lens barrel housing 221. The lower lens barrel housing 221 and the upper lens barrel housing 211 are fastened together with screws.

[0131] A mounting groove is provided on the side of the lower lens barrel housing 221 away from the upper lens barrel assembly 21, and the display module 23 is placed in the mounting groove. The module back plate 24 is located on the side of the display module 23 away from the lower lens barrel assembly 22, and the module back plate 24 is locked to the lower lens barrel housing 221 by screws.

[0132] Referring to Figures 3, 5, 15, and 16, the side of the optical engine 20 with the display module 23 is mounted close to the first housing 11, while the side with the upper lens barrel assembly 21 is mounted away from the first housing 11 and at least partially exposed outside the main housing 10. The display module 23 in the optical engine 20 is used to generate images, which are the virtual content seen by the user during wear. Multiple lenses in the optical engine 20 project images into the user's field of vision through its complex optical system, ensuring clear and accurately focused images so that the user can see a clear virtual image at close range.

[0133] Figure 17 schematically shows an exploded view of the assembly of a support plate in eyeglasses according to some embodiments of the present disclosure. Figure 18 schematically shows an assembly structural diagram of the support plate in eyeglasses according to some embodiments of the present disclosure.

[0134] According to some exemplary embodiments, referring to Figures 3, 17, and 18, the eyeglasses also include a support plate 40, which is disposed within the receiving cavity of the main housing 10. The four corners of the support plate 40 can be locked and fixed to the first housing 11 by screws. Two optical engines 20 are mounted on the support plate 40 through two first mounting holes 121.

[0135] According to some exemplary embodiments, at least one of the two optomechanisms 20 is slidably connected to the support plate 40, and at least one of the two optomechanisms 20 is capable of sliding relative to the support plate 40 along a second direction D2. For example, the two optomechanisms 20 are respectively slidably connected to the support plate 40 along the second direction D2, thereby realizing interpupillary distance adjustment. In addition, the material of the support plate 40 may include metal, and the support plate 40 has high rigidity, which can effectively prevent deflection deformation when the optomechanisms 20 slide.

[0136] According to some exemplary embodiments, referring to Figures 17 and 18, the eyeglasses also include a guide shaft 461. A first guide hole 2211 is provided on the lower lens housing 221 of the optical engine 20, and a second guide hole 462 is provided on the support plate 40 (see Figure 28C for details of the second guide hole 462). The guide shaft 461 passes through the first guide hole 2211 and the second guide hole 462, and extends along a second direction D2, so that the optical engine 20 can slide along the second direction D2 under the guidance of the guide shaft 461. One end of the guide shaft 461 is also provided with a relief groove 4611, on which a hook 4612 is engaged. The hook 4612 protrudes from the surface of the guide shaft 461 to limit the travel of the optical engine 20 along the second direction D2.

[0137] According to some exemplary embodiments, referring to Figures 17 and 18, the head-mounted device A1 further includes a stepper motor 62, the housing of which is fixed to the support plate 40 by screws. The stepper motor 62 includes a slider movable along a second direction D2, the slider being fixed to the optomechanical system 20 by screws. Thus, by controlling the slider to move along the second direction D2, the optomechanical system 20 can be moved along the second direction D2, thereby enabling automatic interpupillary distance adjustment.

[0138] For example, the travel of one stepper motor 62 along the second direction D2 is 8.5mm, and the total travel of two stepper motors 62 along the second direction D2 is 17mm, so the interpupillary distance adjustment range is 0-17mm. The interpupillary distance range of a typical adult is 55-70mm. The minimum distance between the visual axes of the two optical engines 20 along the second direction D2 can be set to 55mm. By moving the stepper motors 62, the maximum distance between the visual axes of the two optical engines 20 along the second direction D2 can be set to 72mm, completely covering the interpupillary distance range of the vast majority of adults.

[0139] According to some exemplary embodiments, referring to Figures 15, 17, and 18, a strip-shaped buckle 2212 is further provided on the side of the lower lens barrel housing 221 of the optical engine 20 near the support plate 40. The strip-shaped buckle 2212 extends along the second direction D2. The strip-shaped buckle 2212 and the first guide hole 2211 are respectively provided on both sides of the optical engine 20 along a third direction D3. The third direction D3 intersects the first direction D1 and the second direction D2. For example, the third direction D3 is perpendicular to the first direction D1 and perpendicular to the second direction D2.

[0140] A strip-shaped slot 47 is provided on the side of the support plate 40 near the optical engine 20. The strip-shaped slot 47 extends along the second direction D2. A strip-shaped buckle 2212 is disposed within the strip-shaped slot 47. The dimension of the strip-shaped buckle 2212 along the second direction D2 is smaller than the dimension of the strip-shaped slot 47 along the second direction D2, allowing the strip-shaped buckle 2212 to move within the strip-shaped slot 47 along the second direction D2. Through the cooperation of the strip-shaped buckle 2212 and the strip-shaped slot 47, the optical engine 20 can be guided to move along the second direction D2, while the optical engine 20 is fixed to prevent it from rotating around the guide shaft 461.

[0141] According to some exemplary embodiments, referring to Figures 15, 16, 17, and 18, the head-mounted device A1 further includes an infrared camera 631 and an infrared fill light 632, both of which are mounted on the optical engine 20. The infrared fill light 632 emits infrared light, and the infrared camera 631 detects the infrared light reflected from the user's eyes to obtain the user's eye position. The stepper motor 62 then drives the optical engine 20 to move to the corresponding position based on the eye position obtained by the infrared camera 631, thereby achieving automatic adjustment of the interpupillary distance.

[0142] The lower lens barrel housing 221 of the optical engine 20 has a first mounting groove 2213 in the area between the two first guide holes 2211. The infrared camera 631 is installed in the first mounting groove 2213 and fixed to the lower lens barrel housing 221 by adhesive. The upper lens barrel housing 211 of the optical engine 20 has a limit post on the side away from the lower lens barrel assembly 22. The infrared fill light 632 can be attached to the limit post by double-sided adhesive.

[0143] According to some exemplary embodiments, referring to Figures 15, 16, and 17, the head-mounted device further includes a Hall sensor 641 and a Hall magnetic stripe 642. One of the Hall sensor 641 and the Hall magnetic stripe 642 is disposed on the optomechanical system 20, and the other is disposed on the support plate 40. The Hall sensor 641 is used to track and identify the position of the Hall magnetic stripe 642. By disposing one of the Hall sensor 641 and the Hall magnetic stripe 642 on the optomechanical system 20 and the other on the support plate 40, the position of the optomechanical system 20 can be identified, thereby assisting the stepper motor 62 in accurately driving the optomechanical system 20 to move to the corresponding position.

[0144] According to some exemplary embodiments, referring to Figures 3, 15, 16, and 17, the lower lens housing 221 of the optical engine 20 has a second mounting groove 2214 on the side near the support plate 40, and the Hall magnetic strip 642 is disposed in the second mounting groove 2214. The support plate 40 includes a first protruding plate 44 protruding towards the optical engine 20, and a second mounting hole 441 is provided on the first protruding plate 44. The Hall sensor 641 is disposed in the second mounting hole 441 and is attached and fixed to the first protruding plate 44 by double-sided adhesive. By providing the first protruding plate 44, the distance between the Hall sensor 641 and the Hall magnetic strip 642 along the first direction D1 can be reduced, thereby improving detection accuracy.

[0145] The Hall magnetic strip 642 is an elongated strip extending along the second direction D2. Through simulation calculation, the size of the Hall magnetic strip 642 along the second direction D2 can be set to 12mm, and the distance between the Hall sensor 641 and the Hall magnetic strip 642 along the first direction D1 can be set to 1mm. Under this size and distance, the relationship curve between the Gaussian value and the displacement approaches a linear relationship, thereby improving the accuracy of position tracking.

[0146] Figure 19 schematically illustrates the structure of the optical mechanism and support plate in one state in eyeglasses according to some embodiments of the present disclosure. Figure 20 schematically illustrates the structure of the optical mechanism and support plate in another state in eyeglasses according to some embodiments of the present disclosure.

[0147] According to some exemplary embodiments, referring to FIG19, based on ergonomics, the distance between the first rotation axes 5211 of the two clamping members 521 located on both sides of the second direction D2 along the second direction D2 can be set to 140mm. When the two optical engines 20 are closest, the distance between their visual axes along the second direction D2 is 55mm. Referring to FIG20, when the two optical engines 20 are farthest apart, the distance between their visual axes along the second direction D2 is 72mm. This achieves interpupillary distance adjustment within the range of 55mm-72mm.

[0148] According to some exemplary embodiments, referring to FIG3, the glasses also include a mainboard 30, which is disposed within the receiving cavity of the main housing 10. The mainboard 30 is electrically connected to the optomechanical system 20, thereby providing electrical signals to the display module 23 in the optomechanical system 20. The mainboard 30 is also electrically connected to other electronic components in the glasses A11, such as Hall sensors and infrared cameras. To satisfy the relevant functions, the mainboard 30 needs to have a relatively large area for arranging components, for example, greater than 3000 mm². 2 Based on this specification, the structure of the motherboard 30 needs to be designed to arrange the hardware reasonably while ensuring functionality, and to compress space as much as possible to ensure the thinness and lightness of the glasses.

[0149] Figures 21A-21B schematically illustrate plan views of a mainboard in eyeglasses according to some embodiments of the present disclosure, wherein Figure 21A shows a plan view of the surface of the mainboard facing the second housing side, and Figure 21B shows a plan view of the surface of the mainboard facing the first housing side.

[0150] Figure 22 schematically illustrates a structural diagram of the optical engine, support plate, and main board assembly in eyeglasses according to some embodiments of the present disclosure. Figure 23 schematically illustrates a structural diagram of the optical engine, support plate, main board, and first housing assembly in eyeglasses according to some embodiments of the present disclosure.

[0151] According to some exemplary embodiments, referring to Figures 21A, 22, and 23, the motherboard 30 is generally rectangular in shape, with a notch on one side. The motherboard 30 has a dimension of 102 mm along the second direction D2 and a dimension of 34 mm along the third direction D3. The motherboard 30 is disposed on the side of the support plate 40 near the first housing 11. The plane on which the motherboard 30 is located is perpendicular to the first direction D1. A portion of the orthographic projection of the motherboard 30 on the support plate 40 lies between the orthographic projections of the two optical engines 20 on the support plate 40. A certain distance needs to be reserved between the motherboard 30 and the support plate 40 to allow space for structures such as the connection lines between the display module and the motherboard 30. For example, the distance along the first direction D1 between the side of the motherboard 30 near the support plate 40 and the side of the support plate 40 near the motherboard 30 can be 4 mm.

[0152] The surface of the first housing 11 near the support plate 40 is arc-shaped. The middle portion of the first housing 11 along the second direction D2 protrudes away from the support plate 40 compared to the two ends of the first housing 11 located in the second direction D2. In order to avoid components of the motherboard 30 near the first housing 11, a safety distance of at least 1 mm should be reserved between the components and the first housing 11. Thus, the distance between the most convex part of the surface of the first housing 11 and the support plate 40 along the first direction D1 is approximately 10.1 mm.

[0153] According to some exemplary embodiments, referring to Figures 21A, 21B, and 23, components are disposed on both sides of the motherboard 30 in the first direction D1. For example, a magnetic wire connector 30a, two infrared camera connectors 30d, and two display module connectors 30e are disposed on the surface of the motherboard 30 near the first housing 11. Another magnetic wire connector 30a, two stepper motor connectors 30b, and two Hall sensor connectors 30c are disposed on the surface of the motherboard 30 near the second housing 12. The two magnetic wire connectors 30a are used for electrical connection with magnetic wires, the two infrared camera connectors 30d are used for electrical connection with two infrared cameras respectively, the two display module connectors 30e are used for electrical connection with two display modules respectively, the two Hall sensor connectors 30c are used for electrical connection with two Hall sensors respectively, and the two stepper motor connectors 30b are used for electrical connection with two stepper motors respectively.

[0154] Figure 24A schematically shows a plan view of the mainboard in eyeglasses according to some embodiments of the present disclosure, wherein Figure 24A shows a plan view of the mainboard near the first housing. Figure 24B schematically shows a top view of the mainboard in eyeglasses according to some embodiments of the present disclosure. Figure 25 schematically shows a structural diagram of the assembly of the optical engine, support plate, mainboard and first housing in eyeglasses according to some embodiments of the present disclosure.

[0155] According to some exemplary embodiments, referring to Figures 24A, 24B, and 25, the main board 30 includes a first sub-board 311, a second sub-board 312, and a flexible connecting plate 32. The first sub-board 311 and the second sub-board 312 are arranged at intervals along a second direction D2 and are electrically connected by the flexible connecting plate 32. The first sub-board 311, the second sub-board 312, and the flexible connecting plate 32 are all located on the side of the support plate 40 near the first housing 11. The plane of the first sub-board 311 is not coplanar with the plane of the second sub-board 312. Both the first sub-board 311 and the second sub-board 312 are inclined relative to the support plate 40, and the inclination directions of the first sub-board 311 and the second sub-board 312 are opposite. The distance between the side of the first sub-plate 311 closest to the second sub-plate 312 and the support plate 40 along the first direction D1 is greater than the distance between the side of the first sub-plate 311 furthest from the second sub-plate 312 and the support plate 40 along the first direction D1. The distance between the side of the second sub-plate 312 closest to the first sub-plate 311 and the support plate 40 along the first direction D1 is greater than the distance between the side of the second sub-plate 312 furthest from the first sub-plate 311 and the support plate 40 along the first direction D1.

[0156] The surface of the first housing 11 near the support plate 40 is arc-shaped. The middle portion of the first housing 11 along the second direction D2 protrudes away from the support plate 40 compared to the two ends of the first housing 11 located in the second direction D2. To reduce the installation space of the main board 30 along the first direction D1, the main board 30 is divided into a first sub-board 311 and a second sub-board 312. The installation orientation of the first sub-board 311 and the second sub-board 312 is adjusted according to the arc shape of the surface of the first housing 11. Both the first sub-board 311 and the second sub-board 312 are inclined relative to the support plate 40, and the inclination directions are opposite. In the inclined first sub-board 311, the distance between one end of the first sub-board 311 along the second direction D2 and the surface of the first housing near the support plate 40 along the first direction D1 can be equal to the distance between the other end of the first sub-board 311 along the second direction D2 and the surface of the first housing near the support plate 40 along the first direction D1. Similarly, in the second sub-plate 312 which is inclined, the distance between one end of the second sub-plate 312 along the second direction D2 and the surface of the first housing near the support plate 40 along the first direction D1 can be equal to the distance between the other end of the second sub-plate 312 along the second direction D2 and the surface of the first housing near the support plate 40 along the first direction D1.

[0157] In this way, the stacking thickness along the first direction D1 can be reduced. For example, the distance between the most convex part of the surface of the first housing 11 and the support plate 40 along the first direction D1 can be reduced to 9.1 mm.

[0158] According to some exemplary embodiments, referring to FIG25, a portion of the orthographic projection of the first sub-board 311 on the support plate 40 is located between the orthographic projections of the two optical engines 20 on the support plate 40, and a portion of the orthographic projection of the second sub-board 312 on the support plate 40 is located between the orthographic projections of the two optical engines 20 on the support plate 40.

[0159] According to some exemplary embodiments, referring to Figures 24A, 24B, and 25, a display module connector 30e, a stepper motor connector 30b, and an infrared camera connector 30d are disposed on the surface of the first sub-board 311 near the first housing 11. A Hall sensor connector 30c and a magnetic wire connector 30a are disposed on the surface of the first sub-board 311 near the second housing 12. The connectors disposed on both sides of the second sub-board 312 can be consistent with those of the first sub-board 311.

[0160] Figures 26A and 26B schematically show plan views of a motherboard in eyeglasses according to some embodiments of the present disclosure, wherein Figure 26A schematically shows a plan view of the surface of the motherboard near the second housing, and Figure 26B schematically shows a plan view of the surface of the motherboard near the first housing.

[0161] Figure 26C schematically shows a top view of a mainboard in eyeglasses according to some embodiments of the present disclosure.

[0162] Figure 27 schematically illustrates a structural diagram of the optical engine, support plate, main board, and first housing assembly in eyeglasses according to some embodiments of the present disclosure.

[0163] According to some exemplary embodiments, referring to Figures 26A to 26C and Figure 27, the motherboard 30 includes a first portion 30M located on the side of the support plate 40 near the first housing 11 and a second portion 30N located on the side of the support plate 40 away from the first housing 11. At least a portion of the orthographic projection of the first portion 30M onto the support plate 40 lies between the orthographic projections of the two optical engines 20 onto the support plate 40, and at least a portion of the second portion 30N lies between the two optical engines 20. The portion of the first housing 11 located between the two optical engines 20 is the most protruding, and the space between this portion and the support plate 40 is relatively large, which can be used to house the first portion 30M of the motherboard 30 without increasing the stacking thickness along the first direction D1. At the same time, the area between the two optical engines on the side of the support plate 40 away from the first housing 11 can be used to house the second portion 30N of the motherboard 30, thus allowing the components to be arranged more compactly within the main housing 10.

[0164] According to some exemplary embodiments, referring to Figures 26C and 27, the first portion 30M may include a first sub-plate 311, and the second portion 30N may include a second sub-plate 312 and a third sub-plate 313, with the third sub-plate 313 located on the side of the second sub-plate 312 away from the support plate 40. The orthographic projection of the second sub-plate 312 onto the support plate 40 at least partially overlaps with the orthographic projection of the first sub-plate 311 onto the support plate 40, and the orthographic projection of the second sub-plate 312 onto the support plate 40 at least partially overlaps with the orthographic projection of the third sub-plate 313 onto the support plate 40. With this configuration, the distance between the most convex part of the surface of the first housing 11 and the support plate 40 along the first direction D1 can be reduced to 6.3 mm.

[0165] According to some exemplary embodiments, referring to Figures 26C and 27, the second sub-board 312 and the third sub-board 313 are located between the two stepper motors 62.

[0166] According to some exemplary embodiments, referring to FIG27, at least a portion of the orthographic projection of the first sub-board 311 on the support plate 40 is located between the orthographic projections of the two optical engines 20 on the support plate 40. At least a portion of the orthographic projection of the optical engine 20 on the support plate 40 does not overlap with the orthographic projection of the first sub-board 311 on the support plate 40. That is, at least a portion of the space between the side of the support plate 40 away from the optical engine 20 and the first housing 11 is not provided with the motherboard 30. In this way, sufficient space can be provided for the connection cable connecting the display module in the optical engine 20 to the motherboard 30. In addition, it also makes the heat generated by the display module during operation transfer to the support plate 40 and then conduct to the outside faster, effectively avoiding the problem of overheating caused by the display module being wrapped by the motherboard 30, which is beneficial to the passive heat dissipation of the whole machine.

[0167] For example, the two ends of the first sub-board 311 along the second direction D2 are located between the visual axis Z1 of one optical engine 20 and the visual axis Z2 of the other optical engine 20. The positions of the visual axes Z1 and Z2 of the optical engines 20 described here should be understood as the positions of the visual axes Z1 and Z2 in the minimum interpupillary distance state. This is beneficial for heat dissipation of the display module in the optical engine 20. On the other hand, restricting the position of the first sub-board 311 along the second direction D2 to between the visual axes Z1 and Z2 of the two optical engines 20 allows for better matching with the arcuate shape of the first housing 11, thereby helping to further reduce the stacking thickness in the first direction D1.

[0168] According to some exemplary embodiments, referring to FIG27, the area of ​​the orthographic projection of the first sub-plate 311 on the support plate 40 is larger than the area of ​​the orthographic projection of the second sub-plate 312 on the support plate 40, and the dimension of the first sub-plate 311 along the second direction D2 is larger than the dimension of the second sub-plate 312; and / or, the area of ​​the orthographic projection of the first sub-plate 311 on the support plate 40 is larger than the area of ​​the orthographic projection of the third sub-plate 313 on the support plate 40, and the dimension of the first sub-plate 311 along the second direction D2 is larger than the dimension of the third sub-plate 313. Since the second sub-plate 312 and the third sub-plate 313 located between the two optical engines 20 need to avoid the space occupied by the movement of the optical engine 20 during interpupillary distance adjustment, the area of ​​the second sub-plate 312 and the third sub-plate 313 needs to be set slightly smaller, while the third sub-plate 313 is located on the side of the support plate 40 closer to the first housing 11, and this problem does not exist, so it can be set larger.

[0169] According to some exemplary embodiments, referring to FIG27, the orthographic projection of the first sub-board 311 on the support plate 40 overlaps with the orthographic projection of the two optical engines 20 on the support plate 40, and the orthographic projection of the first sub-board 311 on the support plate 40 overlaps with the orthographic projection of the two stepper motors 62 on the support plate 40.

[0170] According to some exemplary embodiments, referring to Figures 26C and 27, the main board 30 further includes a fourth sub-board 314, a fifth sub-board 315, a third flexible connecting plate 323, and a fourth flexible connecting plate 324. The fourth sub-board 314 and the fifth sub-board 315 are respectively located on the side of the two optical engines 20 away from the first sub-board 311. The fourth sub-board 314 is electrically connected to the first sub-board 311 through the third flexible connecting plate 323, and the fifth sub-board 315 is electrically connected to the first sub-board 311 through the fourth flexible connecting plate 324. By utilizing the space on both sides of the two optical engines 20 along the second direction D2 to arrange a portion of the main board 30, the space utilization rate within the main housing of the glasses is further improved.

[0171] Figures 28A-28C schematically illustrate the installation process of the main board and support plate in eyeglasses according to some embodiments of the present disclosure.

[0172] Referring to Figure 28A, before installation, the first sub-board 311, second sub-board 312, third sub-board 313, fourth sub-board 314, and fifth sub-board 315 in the main board 30 are all located on one side of the first surface 40X of the support plate 40.

The four corners of the first sub-board 311 are fixed to the support plate 40 with screws. The third flexible connecting plate 323 and the fourth flexible connecting plate 324 are attached to the first surface 40X of the support plate 40 using double-sided tape, and then the fourth sub-board 314 and the fifth sub-board 315 are fixed to the support plate 40 with screws.

[0173] Referring to Figures 28A and 28B, the second sub-plate 312 is flipped to the side of the support plate 40 away from the first sub-plate 311 and fixed to the support plate 40 with screws.

[0174] Referring to Figures 28B and 28C, the third sub-board 313 is flipped to the side of the second sub-board 312 away from the support plate 40, and fixed to the support plate 40 with screws. At this point, the main board 30 and the support plate 40 are assembled.

[0176] Based on the arc-shaped structure of the surface of the first housing 11, the second sub-support plate 42 and the third sub-support plate 43, located on both sides of the second direction D2, are moved a certain distance relative to the first sub-support plate 41 towards the side closer to the second housing 12. This increases the distance between the second sub-support plate 42 and the third sub-support plate 43 and the first housing 11, which is sufficient to accommodate the fourth sub-plate 314, the fifth sub-plate 315, and the components mounted on the fourth sub-plate 314 and the fifth sub-plate 315. As can be seen from Figure 27, the fourth sub-plate 314 and the fifth sub-plate 315 are located closer to the second housing than the first sub-plate 311. The fourth sub-plate 314 is located on the side of the same optical mechanism 20 away from the other optical mechanism 20 along the second direction D2, and the fifth sub-plate 315 is located on the side of the same optical mechanism 20 away from the other optical mechanism 20 along the second direction D2.

[0177] It should be noted that in Figure 27, only the first sub-support plate 41 is schematically shown, while the second sub-support plate 42 and the third sub-support plate 43 are omitted.

[0178] According to some exemplary embodiments, referring to FIG27, the glasses also include at least two perspective cameras 65.
