Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

The present application sets forth a head mounted device. The head-mounted device may be an augmented reality or virtual reality device, such as augmented reality or virtual reality glasses. Of course, the head-mounted device may be other devices that need to be worn on the head, such as glasses, for example, devices that have other functions such as illumination and can be worn on the head, which will not be described again. The following describes in detail an example of augmented reality or virtual reality glasses.

In examples of augmented reality or virtual reality glasses, the head mounted device may be configured to communicate data to and receive data from the external processing device through a signal connection, which may be a wired connection, a wireless connection, or a combination thereof. However, in other cases, the head-mounted device may be used as a stand-alone device, i.e., the data processing is performed at the head-mounted device itself. The signal connection may be configured to carry any kind of data, such as image data (e.g., still images and/or full motion video, including 2D and 3D images), audio, multimedia, voice, and/or any other type of data. The external processing device may be, for example, a game console, personal computer, tablet computer, smart phone, or other type of processing device.

The signal connection may be, for example, a Universal Serial Bus (USB) connection, a Wi-Fi connection, a bluetooth or Bluetooth Low Energy (BLE) connection, an ethernet connection, a cable connection, a DSL connection, a cellular connection (e.g., 3G, LTE/4G or 5G), etc., or a combination thereof. Additionally, the external processing device may communicate with one or more other external processing devices via a network, which may be or include, for example, a Local Area Network (LAN), wide Area Network (WAN), intranet, metropolitan Area Network (MAN), global internet, or a combination thereof.

The head-mounted device may have mounted therein display components, optics, sensors, processors, and the like. In the example of augmented reality or virtual reality glasses, the display component is designed to implement the functionality of the virtual reality glasses, for example by projecting light into the user's eyes, for example by overlaying an image on the user's view of his real world environment. The head-mounted device may also include an ambient light sensor, and may also include a control system to control at least some of the above components and perform associated data processing functions. The control system may include, for example, one or more processors and one or more memories.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a headset device according to an embodiment of the present application, and fig. 2 is an exploded view of the headset device according to the embodiment shown in fig. 1. The head-mounted device 100 may include a frame 10, a wear mechanism 20 coupled to the frame 10, and a lens module 30 mounted on the frame 10. The frame 10 is connected to the wearing mechanism 20 to form a frame structure for wearing together on the head of a user. The frame 10 may be placed in front of the eyes of a user when the headset 100 is worn on the head of the user. The lens module 30 is mounted on the lens frame 10, so that the lens module 30 is worn, and when the user wears the head-mounted device 100, the lens module is placed in front of eyes of the user, and an augmented reality or virtual reality function is realized in front of eyes of the user, and other functions can be realized without repeated description.

The frame 10 may be made of a rigid material such as metal, rubber, plastic, etc. The frame 10 may be a frame structure or a shell structure.

The frame 10 may include a first sub-frame 11 and a second sub-frame 12 connected together. The first sub-frame 11 and the second sub-frame 12 can be matched with each other to mount the lens module 30. The first sub-frame 11 and the second sub-frame 12 may be symmetrically disposed. The lens frame 10 can be arranged on the nose bridge of a user between the first sub-lens frame 11 and the second sub-lens frame 12 so as to support the lens frame 10. Of course, in some embodiments, the frame 10 may not need to be mounted on the bridge of the nose of the user and worn on the head of the user with the fit of the wear mechanism 20.

It should be noted that the terms "first," "second," and the like herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more of the described features.

The first sub-frame 11 and the second sub-frame 12 may be ring-shaped structures such as rectangular ring-shaped structures, irregular ring-shaped structures, circular ring-shaped structures, elliptical ring-shaped structures, etc. Of course, the first sub-frame 11 may also have a semi-annular structure or other structures, which will not be described in detail.

The first sub-frame 11 may be set corresponding to the left eye of the user. The second sub-frame 12 may be set corresponding to the user's right eye.

It will be appreciated that one of the first sub-frame 11 and the second sub-frame 12 may be omitted. In some embodiments, camera modules, sensors, etc. may also be mounted to the frame 10.

The wearing mechanism 20 is used for wearing on the head of a user, and can be connected and fixed with the glasses frame 10 to form the frame structure 10. The wearing mechanism 20 may include a first temple 21 fixedly connected to the frame 10, for example, the first sub-frame 11, and a second temple 22 fixedly connected to the frame 10, for example, the second sub-frame 12, and symmetrically mounted to the first temple 21. The first temple 21 may be mounted on the left ear, and the second temple 22 may be mounted on the right ear, so as to implement wearing of the wearing mechanism 20.

The first temple 21 and the second temple 22 may be made of a rigid material such as metal, rubber, plastic, etc., and of course, may be made of the same material as the frame 10.

In some embodiments, the first temple 21 and the second temple 22 may each be rotatably connected to the frame 10. Further, the fixed end of the first temple 21 is rotatably connected to the lens frame 10, and when the first temple 21 rotates relative to the lens frame 10, the free end of the first temple 21 moves toward the side closer to or away from the second temple 22. And the fixed end of the second glasses leg 22 is rotatably connected with the glasses frame 10, and when the second glasses leg 22 rotates relative to the glasses frame 10, the free end of the second glasses leg 22 moves towards one side close to or far from the first glasses leg 21.

It will be appreciated that the wearing mechanism 20 may be provided in other configurations, such as a ring-like configuration, a half-ring-like configuration, etc. In some scenarios, the wearing mechanism 20 may be a structure such as a lace, a semi-annular structure, a ring structure, etc. that may be worn directly on the head of the user, and the frame 10 may be mounted on the wearing mechanism 20 to enable wearing of the frame 10 and the lens module 30, so that the frame 10 may not contact the nose bridge of the user. In some scenarios, wearing mechanism 20 may also be a hat-like structure, as if a hat were fitted directly over the user's head.

In addition, in some embodiments, the first temple 21 and the second temple 22 may be cooperatively configured with a battery, a processor, an optical machine, a sensor, and the like. Of course, in some scenarios, the lens frame 10 may also be used to mount a light machine, so that the light machine cooperates with the lens module 30 to realize the transmission and display of the image light beam.

The lens module 30 may be made of one or more transparent or translucent materials such as glass, plastic, etc. The lens module 30 may also be made of one or more of transparent material, translucent material, opaque material, etc. for a specific light transmission effect.

The lens module 30 may include 2. Specifically, one is a lens module 31, and the other is a lens module 32. The lens module 31 is mounted on a frame 10, such as the first sub-frame 11. The lens module 32 is mounted on the frame 10, e.g., the second sub-frame 12. The lens module 31 and the lens module 32 may be symmetrically arranged such that the lens module 31 may be arranged corresponding to the left eye of the user and the lens module 32 may be arranged corresponding to the right eye of the user. In some embodiments, when the first sub-frame 11 is omitted, the lens module 31 may be omitted as well. Of course, when the second sub-frame 12 is omitted, the lens module 32 may be omitted as well.

The lens module 31 and the lens module 32 may each include at least one functional lens.

In one embodiment, the functional lens may be a vision correction lens made of one or more of convex lens and concave lens. In one embodiment, the functional lens may be a near vision lens.

Of course, other types of lenses or functional lenses (e.g., flat mirrors, antiglare mirrors, colored mirrors, etc.) or functional films (e.g., antireflection films, polarizing films, filter films, etc.) may also be provided in the vision correcting lenses. That is, other types of lenses or functional lenses (e.g., flat mirrors, antiglare mirrors, colored mirrors, etc.) or functional films (e.g., antireflection films, polarizing films, filter films, etc.) may also be used as functional lenses.

In an embodiment, the functional lens may be an optical waveguide, in particular a planar grating waveguide such as a diffraction grating waveguide. The headset 100 may present virtual reality/augmented reality through a functional lens.

It should be understood that the lens module 31 and the lens module 32 may be a lens laminated structure formed by combining the functional lenses in any of the above embodiments, and will not be described herein.

In addition, the laminated structure of the lens module 31 and the laminated structure of the lens module 32 may be different from each other or the same in the illustrated embodiment.

Referring to fig. 3, fig. 3 is a cross-sectional view taken along line iii-iii of the embodiment of fig. 2 where the frame 10 and the lens module 30 are mated. The lens module 31 may be a hybrid laminate of a myopic lens and an optical waveguide. The lens module 31 may include a first myopia lens 33, an optical waveguide assembly 34, and a second myopia lens 35 sequentially stacked on an optical axis y. The ambient light propagating on the optical axis y can sequentially pass through the first myopia lens 33, the optical waveguide assembly 34 and the second myopia lens 35. That is, in some cases, the optical axis y may be considered as the lamination direction of the first myopia lens 33, the optical waveguide assembly 34, and the second myopia lens 35.

The optical waveguide assembly 34 may include at least one of the functional lenses of the above embodiments, with one of the functional lenses being an optical waveguide.

The optical waveguide assembly 34 and the second near vision lens 35 may be secured to the frame 10, e.g., the first sub-frame 11, by adhesive, snap-fit, screw-fit, welding, or the like. In some embodiments, the optical waveguide assembly 34 and the second near vision lens 35 may be secured together by bonding, clamping, screwing, welding, etc. such that the optical waveguide assembly 34 or the second near vision lens 35 is secured to the frame 10, e.g., the first sub-frame 11, by bonding, clamping, screwing, welding, etc.

The ambient light is superimposed with the image beam from the light engine through the light guide assembly 34 to achieve augmented reality.

It will be appreciated that the order of lamination of the first myopic lens 33, the optical waveguide assembly 34 and the second myopic lens 35 may be adjusted in some embodiments. For example, the second myopia lens 35 may be located between the first myopia lens 33 and the optical waveguide assembly 34. For example, the first myopia lens 33 can be located between the second myopia lens 35 and the optical waveguide assembly 34. For example, the first myopia lens 33 is closest to the user's eye than the second myopia lens 35 when the user wears the headset 100. For example, the first myopia lens 33 is furthest from the user's eyes than the second myopia lens 35 when the user wears the headset 100.

Optical waveguide assembly 34 may be provided with an optical coupling-in portion and an optical coupling-out portion. The light coupling-in and light coupling-out portions are connected together to form an optical path from which an image beam of the optical engine is coupled into the optical waveguide assembly 34 for transmission within the optical path, and finally the image beam is coupled out of the optical waveguide assembly 34 at the light coupling-out portion for injection into the eye of the wearer and imaging onto the retina. In some embodiments, ambient light may propagate on the optical axis y through the optical waveguide assembly 34 to overlap with the image beam coupled out by the light coupling-out light section, enter the wearer's eye and image on the retina, enabling augmented reality.

Referring to fig. 3, the first myopia lens 33 may have a first surface 331 far from the optical waveguide assembly 34, a second surface 332 near the optical waveguide assembly 34, and a side surface 333 connecting the first surface 331 and the second surface 332.

The first myopia lens 33 and the second myopia lens 35 cooperate to correct the vision of the user so that the user can clearly see objects. However, in some situations, the first myopia lens 33 and the second myopia lens 35 are fixed relatively, so that the total myopia degree of the lens module 31 is not variable, and cannot be fit for most people.

Referring to fig. 3, the head-mounted device 100 may further include an adjustment mechanism 40 disposed between the lens module 31, e.g., the first near vision lens 33, and the frame 10, e.g., the first sub-frame 11. The adjustment mechanism 40 has a locked state in which the first myopia lens 33 and the frame 10, for example, the first sub-frame 11 are fixed relative to each other, and an unlocked state in which the first myopia lens 33 is slidable relative to the frame 10, for example, the first sub-frame 11.

It can be understood that the adjusting mechanism 40 drives the first myopia lens 33 to slide, and simultaneously completes the continuous adjustment of the distance between the first myopia lens 33 and the second myopia lens 35, so as to adjust the comprehensive myopic degree of the lens module 31 by changing the distance between the first myopia lens 33 and the second myopia lens 35.

In one embodiment, the overall myopia degree of the lens module 31 is:

D＝100N＝100(N1+N2-d*N1*N2)；

wherein:

d: the integrated near vision power of the lens module 31;

n1: diopter of the first near vision lens 33;

n2: diopter of the second near vision lens 35;

n: the overall diopter of the lens module 30;

d: the distance between the optical center of the first myopia lens 33 and the optical center of the second myopia lens 35 (the distance between the first myopia lens 33 and the second myopia lens 35 on the optical axis y) is in m.

Therefore, the comprehensive myopia degree D is positively correlated with the distance D, and the distance D can be adjusted to adjust the comprehensive myopia degree D. For example, by increasing the distance D, the overall myopic degree D will become greater. For example, by adjusting the distance D, the overall myopic degree D will be smaller.

Referring to fig. 3, 4 and 5, fig. 4 is a schematic view of the embodiment shown in fig. 3 in an unlocked state when the lens frame 10, for example, the first sub-lens frame 11, and the lens module 31 are assembled, and fig. 5 is a schematic view of the embodiment shown in fig. 3 in a locked state when the lens frame 10, for example, the first sub-lens frame 11, and the lens module 31 are assembled. The adjustment mechanism 40 can continuously adjust the distance D when the first myopia lens 33 slides relative to the lens frame 10, such as the first sub-lens frame 11, so that the integrated myopia degree D can be continuously adjusted, and the head-mounted device 100 can be worn by a plurality of people without being limited by the myopia degree of eyes of the user.

Referring to fig. 3, 4 and 5, the adjustment mechanism 40 may include a locking assembly 41 and a displacement assembly 42 disposed between the lens module 31, e.g., the first near vision lens 33, and the frame 10, e.g., the first sub-frame 11. The locking assembly 41 is used to secure the first near vision lens 33 to the frame 10, e.g., the first sub-frame 11, when the adjustment mechanism 40 is switched from the unlocked state to the locked state. The displacement assembly 42 is used to generate a magnetic force. When the adjustment mechanism 40 is in the unlocked state, the displacement assembly 42 drives the first near vision lens 33 to slide toward a side closer to or farther from the second near vision lens 35 relative to the frame 10, e.g., the first sub-frame 11, by generating a magnetic force.

The locking component 41 is used for clamping the first myopia lens 33 on the lateral peripheral surface 333 of the first myopia lens 33, so that the adjusting mechanism 40 is in a locked state. The locking assembly 41 may also be unlocked. The locking assembly 41 may include a first biasing member 411 for biasing the first near vision lens 33, e.g., the side peripheral surface 333, a locking member 412 provided on the frame 10, e.g., the first sub-frame 11, for contact clamping with the first near vision lens 33, e.g., the side peripheral surface 333, and a first electromagnetic assembly 413 for generating a magnetic force. Under the action of the first urging member 411, the locking member 412 may be engaged with the first myopia lens 33, for example, the side surface 333, so as to lock the adjustment mechanism 40. The first electromagnetic assembly 413 generates a magnetic force and overcomes the force of the first force application member 411 to place the adjustment mechanism 40 in the unlocked state. Of course, when the first urging member 411 does not apply the urging force to the first myopia lens 33, for example, the side peripheral surface 333, the adjustment mechanism 40 may be also put in the unlocked state.

The first force application member 411 may be an elastic member such as a spring, a spring plate, a structure with elasticity, or a structure with an elastic member such as a telescopic rod. The first force application member 411 may apply a force to the first myopia lens 33 under the elastic force of the elastic member.

The first urging member 411 may be fixed to the frame 10, for example, the first sub-frame 11, by means of contact, fastening, adhesion, screwing, fastening, or the like, and may be in contact with the first myopia lens 33, for example, the side peripheral surface 333. Of course, the first urging member 411 may be fixed to the first myopia lens 33, for example, the side peripheral surface 333 by means of contact, fastening, adhesion, screwing, fastening, or the like, and may be abutted against the lens frame 10, for example, the first sub-lens frame 11.

The first force application member 411 may be provided in plural to be disposed around the first myopia lens 33, and apply force to the first myopia lens 33.

In another embodiment, the first urging member 411 may also include two magnets disposed in opposite directions, one of which is disposed on the frame 10, for example, the first sub-frame 11, and the other of which is disposed on the first near vision lens 33, for example, the side surface 333.

In some embodiments, the first force application member 411 may apply a force to the first near vision lens 33 in the x-direction. In some scenarios, the x-direction may be disposed perpendicular to the optical axis y.

The locking member 412 may be fixed to the frame 10, for example, the first sub-frame 11, by abutment, clamping, adhesive, screwing, clamping, or the like. In one embodiment, the latch 412 may be part of the frame 10, such as the first sub-frame 11.

The locking member 412 is used for contacting with the first near-sighted lens 33, for example, the side surface 333, so as to limit and fix the first near-sighted lens 33 on the optical axis y, so that the adjusting mechanism 40 is in a locked state, and the first near-sighted lens 33 is prevented from sliding on the optical axis y.

In one embodiment, the locking member 412 has a friction surface 4121 to contact the first near vision lens 33, e.g., the lateral surface 333. The first myopia lens 33 is pressed against the friction surface 4121 of the lock member 412 by the force of the first urging member 411. Further, static friction is generated on the friction surface 4121, so that the first myopia lens 33 is prevented from sliding on the optical axis y by the static friction, and the friction surface 4121 is contacted and clamped with the first myopia lens 33, for example, the side peripheral surface 333.

In some embodiments, referring to fig. 6, fig. 6 is a schematic structural diagram of the first myopia lens 33 of fig. 3 mated with the locking member 412. For better retention of the first myopia lens 33 on the optical axis y, a retaining structure may be provided on the locking member 412 to retain with a retaining structure provided on the side peripheral surface 333. In some embodiments, the clamping structure may be a latch.

The first electromagnetic assembly 413 is used to effect the switching of the adjustment mechanism 40 from the locked state to the unlocked state. The first electromagnetic assembly 413 may include a first magnetic member 4131 disposed on the side peripheral surface 333 and a first electromagnetic member 4132 disposed on the frame 10, e.g., the first sub-frame 11, and disposed opposite the first magnetic member 4131.

The first magnetic member 4131 may be a permanent magnet, or the first magnetic member 4131 may be an electromagnet, or may be energized to generate a magnetic field. The first magnetic member 4131 may be fixed to the side circumferential surface 333 by abutment, clamping, adhesion, screwing, clamping, or the like.

The first electromagnetic member 4132 may be energized to generate a magnetic field so as to generate a magnetic force with the first magnetic member 4131, so as to apply a magnetic force on the first myopia lens 33, for example, the side peripheral surface 333, so that when the first myopia lens 33 overcomes the force of the first force application member 411, the first myopia lens 33 has a tendency to move to a side far away from the locking member 412, static friction on the friction surface 4121 is reduced, even the locking member 412 is not in contact with the first myopia lens 33, for example, the side peripheral surface 333, or the locking structure on the locking member 412 is separated from the locking structure on the side peripheral surface 333, so that the adjusting mechanism 40 is in the unlocking state.

The first electromagnetic member 4132 may be fixed to the frame 10, for example, the first sub-frame 11, by abutment, clamping, adhesion, screwing, clamping, or the like.

Referring to fig. 3, 4 and 5, the displacement assembly 42 may include a second force applying member 421 disposed between the first near vision lens 33, e.g., the first surface 331, and the frame 10, e.g., the first sub-frame 11, for applying a force to the first surface 331, and a second electromagnetic assembly 422 disposed between the first near vision lens 33, e.g., the second surface 332, and the frame 10, e.g., the first sub-frame 11, for applying a magnetic force to the second surface 332. When the adjusting mechanism 40 is in the unlocked state, the resultant force of the acting force of the second force application member 421 and the magnetic acting force of the second electromagnetic assembly 422 drives the first myopia lens 33 to slide towards the side close to or far from the second myopia lens 35, so that the adjustment of the distance d is realized. Of course, in some embodiments, when overcoming the static friction between the locking component 41, such as the side circumferential surface 333 and the friction surface 4121, the resultant force of the acting force of the second force application member 421 and the magnetic acting force of the second electromagnetic component 422 drives the first myopia lens 33 to slide towards the side close to or far from the second myopia lens 35, so as to achieve the adjustment of the distance d.

The second force application member 421 may be an elastic member such as a spring, a spring plate, a structure with elasticity, or a structure with an elastic member such as a telescopic rod. The second force application member 421 can apply a force to the first myopia lens 33 under the elastic force of the elastic member.

The second force application member 421 may be fixed to the frame 10, for example, the first sub-frame 11, by means of abutment, fastening, adhesion, screwing, fastening, or the like, and may abut against the first near vision lens 33, for example, the first surface 331. Of course, the second force application member 421 may be fixed to the first myopia lens 33, for example, the first surface 331, by means of contact, fastening, adhesion, screwing, fastening, or the like, and may abut against the lens frame 10, for example, the first sub-lens frame 11.

In another embodiment, the second force applying member 421 may include two magnets disposed in opposite directions, one disposed on the frame 10, such as the first sub-frame 11, and the other disposed on the first near vision lens 33, such as the first surface 331.

The second electromagnetic assembly 422 may include a second magnetic member 4221 disposed on the first near vision lens 33, e.g., the second surface 332, and a second electromagnetic member 4222 disposed on the frame 10, e.g., the first sub-frame 11, opposite the second magnetic member 4221.

The second magnetic member 4221 may be a permanent magnet, or the second magnetic member 4221 may be an electromagnet, or may be energized to generate a magnetic field. The second magnetic member 4221 may be fixed to the second surface 332 by means of abutment, clamping, adhesion, screwing, clamping, etc.

The second electromagnetic member 4222 may be energized to generate a magnetic field to generate a magnetic force with the second magnetic member 4221. Further, when the adjusting mechanism 40 is in the unlocked state, the second electromagnetic member 4222 cooperates with the second magnetic member 4221 to generate a magnetic force, and the resultant force of the magnetic force and the force of the second force application member 421 drives the first myopia lens 33 to slide toward a side close to or far from the second myopia lens 35, so as to adjust the distance d. In some embodiments, the second electromagnetic member 4222 cooperates with the second magnetic member 4221 to generate a magnetic force, and the magnetic force is combined with the force of the second force application member 421 to drive the first myopia lens 33 to slide towards the side close to or far from the second myopia lens 35 when overcoming the static friction between the side peripheral surface 333 and the friction surface 4121, so as to achieve the adjustment of the distance d.

The second electromagnetic member 4222 may be fixed to the frame 10, for example, the first sub-frame 11, by means of abutment, fastening, adhesive, screwing, fastening, or the like.

In an embodiment, referring to fig. 7, fig. 7 is a schematic view of the embodiment of fig. 3 in a locked state when the lens frame 10, for example, the first sub-frame 11 and the lens module 31 are assembled. The first surface 331 is a surface facing the optical waveguide assembly 34. Second surface 332 is the surface on the side remote from optical waveguide assembly 34. That is, the surface facing the side of the optical waveguide assembly 34 may be referred to as a first surface, and correspondingly, the surface facing away from the side of the optical waveguide assembly 34 may be referred to as a second surface. Alternatively, the surface facing the side of the optical waveguide assembly 34 may be referred to as a second surface, and correspondingly, the surface facing away from the side of the optical waveguide assembly 34 may be referred to as a first surface. Further, the second urging member 421 is provided between the first myopia lens 33, for example, the first surface and the frame 10, for example, the first sub-frame 11. The second electromagnetic assembly 422 is disposed between the first near vision lens 33, e.g., the second surface, and the frame 10, e.g., the first sub-frame 11.

It can be understood that the resultant force of the magnetic force generated by the second electromagnetic assembly 422 and the force of the second force application member 421 can keep the first myopia lens 33 sliding on the optical axis y when the adjusting mechanism 40 is in the unlocked state, and certainly when the resultant force of the magnetic force generated by the second electromagnetic assembly 422 and the force of the second force application member 421 is larger than the maximum friction force between the side circumferential surface 333 and the friction surface 4121, the sliding of the first myopia lens 33 on the optical axis y can also keep the side circumferential surface 333 and the friction surface 4121 in the unlocked state, that is, the pressure between the side circumferential surface 333 and the friction surface 4121 of the force of the first force application member 411 can be adjusted only by the magnetic force of the first electromagnetic assembly 413.

In addition, in the above embodiment, when the specific structure of the adjusting mechanism 40 is provided on the surface of the first myopia lens 33, for example, the first surface 331, the second surface 332, and the side peripheral surface 333, it may be indicated that the adjusting mechanism 40 is provided only on the surface of the first myopia lens 33, or that a groove is provided through the surface of the first myopia lens 33 to provide the specific structure of the adjusting mechanism 40 in the groove.

Furthermore, the lens module 32 may be configured in a laminated structure like the lens module 31. The lens module 32 and the frame, such as the second sub-frame 12, may also be provided with an adjustment mechanism 40. Specifically, the matching relationship and the arrangement relationship between the lens module 32, the lens frame such as the second sub-lens frame 12, and the adjusting mechanism 40 can be referred to the matching relationship and the position relationship between the lens module 31, the lens frame 10 such as the first sub-lens frame 11, and the adjusting mechanism 40 in the embodiments, and will not be described in detail.

Referring to fig. 8, fig. 8 is an exploded view of the first myopia lens 33, the second magnetic member 4221, the second electromagnetic member 4222, and the second force application member 421 according to the embodiment shown in fig. 3. The second force application member 421 may be a spring, and has a larger radius, and further may contact with the edge of the first surface 331 of the first near-sighted lens 33, so as to ensure that the first near-sighted lens 33 is uniformly stressed and can translate on the optical axis y when the first near-sighted lens 33 slides. The second magnetic member 4221 and the second electromagnetic member 4222 are both in a ring-shaped structure and are disposed opposite to each other. The second magnetic member 4221 may contact the edge of the first myopia lens 33 on the second surface 332, so that the first myopia lens 33 is uniformly stressed to ensure that the first myopia lens 33 translates on the optical axis y when sliding.

It will be appreciated that other arrangements may be employed to achieve stable translation of the first myopic lens 33.

For example, referring to fig. 9, fig. 9 is an exploded view of the first myopia lens 33, the second magnetic member 4221, the second electromagnetic member 4222, and the second force application member 421 in the embodiment shown in fig. 3. The second force application member 421 has a structure including an elastic member. The second force applying member 421 may include an elastic member 4211 disposed between the first near vision lens 33, e.g., the first surface 331, and the frame 10, e.g., the first sub-frame 11, and a telescopic rod 4212 having one end fixed to the frame 10, e.g., the first sub-frame 11. Wherein one end of the telescoping rod 4212 is connected to a first near vision lens 33, such as a first surface 331. The telescopic rod 4212 is used for telescopic on the optical axis y, so that the telescopic rod 4212 is guided on the optical axis y, and the first myopia lens 33 is stably translated.

In some embodiments, one end of the telescoping rod 4212 slides with the first near vision lens 33 in the x-direction to avoid spatial interference of the locking assembly 41 with the displacement assembly 42. In some embodiments, the first near vision lens 33 is provided with a sliding rail 334 on the first surface 331 such that the telescoping rod 4212 slides on the sliding rail 334 to effect sliding in the x-direction.

In some embodiments, the resilient member 4211 is disposed on the telescoping rod 4212.

For example, referring to fig. 10, fig. 10 is a schematic structural diagram of the embodiment shown in fig. 3 when the first myopia lens 33 is combined with the second magnetic member 4221, the second electromagnetic member 4222 and the second force application member 421. The second force applying member 421 may include an elastic member 4211 disposed between the first near vision lens 33, e.g., the first surface 331, and the frame 10, e.g., the first sub-frame 11, and a guide member 4213 fixed to the frame 10, e.g., the first sub-frame 11, and slidably coupled to the first near vision lens 33. The guide 4213 is extended on the optical axis y so that the first myopia lens 33 translates on the optical axis y.

It can be appreciated that, due to the guide member 4213, the first near vision lens 33 cannot move in the x direction, and thus, in some situations, it may occur that the adjustment mechanism 40 cannot be switched between the unlocked state and the locked state, for example, the locking structure on the locking member 412 and the locking structure on the side peripheral surface 333 cannot be separated from each other. Thus, a fit adjustment of the locking assembly 41 is required in some embodiments.

Referring to fig. 10, the locking assembly 41 may include a locking member 412 for contacting and fastening with the first near vision lens 33, such as the side surface 333, a first urging member 411 disposed between the locking member 412 and the lens frame 10, such as the first sub-lens frame 11, and a first electromagnetic assembly 413 disposed between the locking member 412 and the lens frame 10, such as the first sub-lens frame 11. The first urging member 411 applies an urging force to the locking member 412, and thereby the locking member 412 is brought into contact with and locked with the first myopia lens 33, for example, the side peripheral surface 333, so that the adjustment mechanism 40 is in a locked state. The first electromagnetic assembly 413 applies a magnetic force to the lock member 412 that overcomes the force of the first force application member 411 to place the adjustment mechanism 40 in the unlocked state.

The first electromagnetic assembly 413 may include a first magnetic member 4131 disposed on the latch 412 and a first electromagnetic member 4132 disposed on the frame 10, e.g., the first sub-frame 11, opposite the first magnetic member 4131.

It should be understood that, for the partial structures of the first urging member 411, the locking member 412 and the first electromagnetic assembly 413, the first urging member 411, the locking member 412 and the first electromagnetic assembly 413 are not changed due to the adjustment of the locking assembly 41, so the description of the first urging member 411, the locking member 412 and the first electromagnetic assembly 413 in the above embodiment is omitted here.
