[0064] It can be understood that names such as "first lens", "second lens" and "lens" can be converted with each other in some embodiments. For example, in one embodiment, the "first lens" in other embodiments is called the "second lens", and correspondingly, the "second lens" in other embodiments is called the "first lens".

[0065] Taking the first functional lens 20 as an example of an optical waveguide, lenses (such as the first lens 21 and the second lens 22) can be provided with a light coupling inlet and a light coupling outlet. The light coupling inlet and the light coupling outlet are connected together to form an optical path. Light is coupled into the lens from the light coupling inlet, transmitted within the optical path, and finally the light will be coupled out of the lens at the light coupling outlet, entering the wearer's eye and imaging on the retina.

[0066] Understandably, in one embodiment, at least one of the first lens 21 and the second lens 22 can be omitted. In some embodiments, the first functional lens 20 can be omitted.

[0067] Please refer to Figure 3 , the wearing body 30 can be used to be worn on the user's head. The wearing body 30 is located in front of the user's eyes.

The second mounting frame 32 can be a ring structure such as a rectangular ring structure, an irregular ring structure, a circular ring structure, an oval ring structure, etc. Of course, the second mounting frame 32 can also be a semi-ring structure or other structures, which will not be elaborated. The second mounting frame 32 can be formed at the edge of the first functional lens 20, such as the second lens 22, to be connected and fixed to the first functional lens 20, such as the second lens 22. In one embodiment, the second mounting frame 32 surrounds the edge of the first functional lens 20, such as the second lens 22.

[0071] The second mounting frame 32 can form a second mounting portion 321 at one end away from the first mounting frame 31 for mounting the support portion 40. The second mounting portion 321 and the first mounting portion 311 are located on the same side of the wearing body 30. In one embodiment, the second mounting portion 321 can be a rotating shaft.

[0072] It can be understood that names such as "first mounting portion", "second mounting portion" and "mounting portion" can be converted into each other in some embodiments. For example, in one embodiment, the "first mounting portion" in other embodiments is referred to as the "second mounting portion", and correspondingly, the "second mounting portion" in other embodiments is referred to as the "first mounting portion".

[0073] The connecting member 33 can be made of the same material as the first mounting frame 31 or the second mounting frame 32, and of course, it can also be made of other rigid materials. The connecting member 33 is located between the first mounting frame 31 and the second mounting frame 32 and is used to connect the first mounting frame 31 and the second mounting frame 32 so that the first mounting frame 31 and the second mounting frame 32 become an integral body, so that the first mounting frame 31 and the second mounting frame 32 are spaced apart, and a nose pad portion 34 is formed between the first mounting frame 31 and the second mounting frame 32, so that the wearing body 30 can be mounted on the user's nose bridge.

[0077] Please refer toFigure 3 The supporting part 40 is for wearing on the user's head and can be connected and fixed to the wearing main body 30 to form a frame structure 10. The supporting part 40 may include a first leg 41 connected to the first mounting frame 31, such as the first mounting portion 311, and a second leg 42 connected to the second mounting frame 32, such as the second mounting portion 321 and symmetrically mounted with the first leg 41. Among them, the first leg 41 can be placed on the right ear, and the second leg 42 can be placed on the left ear to realize the wearing of the supporting part 40. Of course, the supporting part 40 can also be arranged in other forms such as a ring structure, a semi-ring structure, etc.

[0078] It can be understood that names such as "first leg", "second leg" and "leg" can be converted with each other in some embodiments. For example, in one embodiment, the "first leg" in other embodiments is referred to as the "second leg", and correspondingly, the "second leg" in other embodiments is referred to as the "first leg".

[0079] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 respectively disclose an exploded view of a perspective of the first leg 41 in the embodiment shown in the present application Figure 3 The first leg 41 may include a leg main body 411 connected to the first mounting frame 31, such as the first mounting portion 311, a leg side cover 412 buckled with the leg main body 411 to form an accommodation space 4110, a first battery module 413 installed inside the accommodation space 4110, and a first connection component 414 arranged in the accommodation space 4110 and used for installing an external component 400.

[0080] The leg main body 411 is made of a rigid material such as metal, rubber, plastic, etc. Of course, it can also be made of the same material as the wearing main body 30. The leg main body 411 can be in an overall strip-shaped shell structure. One end of the leg main body 411 connected to the first mounting frame 31, such as the first mounting portion 311, is provided with an assembly portion 4111. In one embodiment, the assembly portion 4111 can be a hole for pivotally connecting with the first mounting portion 311, such as a rotating shaft, so that the leg main body 411 is rotatably connected to the first mounting frame 31. When the leg main body 411 rotates relative to the first mounting frame 31, the end of the leg main body 411 far from the first mounting portion 311 moves towards the second leg 42 side, and thus the folding and storage of the wearing component 200 can be realized, thereby reducing the occupied space of the wearing component 200. When the leg main body 411 rotates relative to the first mounting frame 31, the end of the leg main body 411 far from the first mounting portion 311 moves towards the side away from the second leg 42, and thus the wearing component 200 is unfolded. Of course, the assembly portion 4111 and the first mounting portion 311 can also be connected and fixed in other ways such as bonding, plugging, welding, clamping, etc., which will not be elaborated.

[0081] An accommodation space 4110 is provided inside the leg main body 411 to accommodate the first battery module 413 and the first connection component 414. Of course, when the host for implementing augmented reality, virtual reality functions, and / or other functions in the head-mounted device 100 is provided on the leg main body 411, the host can be placed in the accommodation space 4110.

[0082] In one embodiment, a partition plate 4112 can be provided in the accommodation space 4110 of the leg main body 411 to divide the accommodation space 4110 into multiple sub-spaces, such as a first installation space 411a in the middle and second installation spaces 411b and 411c on both sides of the first installation space 411a. The partition plate 4112 can also be used to strengthen the strength of the leg main body 411. Of course, in some embodiments, the partition plate 4112 can be omitted.

[0083] It can be understood that names such as "first installation space", "second installation space", and "installation space" can be converted into each other in some embodiments. For example, in one embodiment, the "first installation space" in other embodiments is referred to as the "second installation space", and correspondingly, the "second installation space" in other embodiments is referred to as the "first installation space".

[0084] The leg main body 411 opens an opening 41a on the side away from the second leg 42 to communicate with the accommodation space 4110, so that a leg side cover 412 can be covered at the opening 41a. Of course, the opening 41a can also be opened on the side of the leg main body 411 close to the second leg 42. Correspondingly, the leg side cover 412 is installed on the side of the leg main body 411 facing the second leg 42.

[0085] The leg side cover 412 can be made of a hard material such as metal, rubber, plastic, etc., or can be made of the same material as the leg main body 411. The leg side cover 412 can be a plate-like structure, and its size and shape can be similar to the opening 41a, so that the opening 41a can be covered on the leg main body 411. In one embodiment, when the leg side cover 412 is covered on the leg main body 411, the accommodation space 4110 is a closed space.

[0086] In one embodiment, please refer to Figure 4 and Figure 6 , Figure 6 This application is disclosed Figure 4Schematic diagram of the connection structure between the leg main body 411 and the leg side cover 412 in the illustrated embodiment. The leg side cover 412 covers the portion corresponding to the opening 41a and the first installation space 411a, so that the leg side cover 412 and the leg main body 411 form an installation opening 41b at the portion corresponding to the second installation space 411b, and form an installation opening 41c at the portion corresponding to the second installation space 411c. The installation openings 41b and 41c are used to cooperate with the first connection component 414 and the external hanging component 400. Of course, the installation openings 41b and 41c can also be provided on the leg side cover 412 when the leg side cover 412 completely blocks the opening 41a.

[0087] The leg side cover 412 is provided with an installation hole 412a, and the installation hole 412a communicates with the accommodation space 4110, such as the first installation space 411a, to cooperate with the first battery module 413.

[0088] In one embodiment, the leg side cover 412 can be replaced by a display component and / or a button component. The display component and / or the button component can be electrically connected to the host inside the head-mounted device 100 to input control instructions into the head-mounted device 100 to realize the control of the head-mounted device 100. Of course, when the leg side cover 412 is replaced by the display component, it can be used as an output device to output messages such as the working state of the head-mounted device 100 to the user.

[0089] In one embodiment, the leg side cover 412 and the leg main body 411 can be of an integral structure.

[0090] It can be understood that when the leg side cover 412 is installed on the side of the leg main body 411 close to the second leg 42, the installation openings 41b and 41c and the installation hole 412a can be correspondingly provided on the leg main body 411, and the display component and / or the button component can also be correspondingly provided on the leg main body 411.

[0091] The second leg 42 is symmetrically arranged with the first leg 41 so that the second leg 42 and the first leg 41 cooperate to realize wearing the wearing component 200 on the user's head. The second leg 42 can be arranged in the same way as the first leg 41 described above. For example, in some embodiments, the second leg 42 can be connected to the second mounting frame 32 in the same way as the first leg 41 is connected to the first mounting frame 31. When the first leg 41 rotates relative to the first mounting frame 31, the end of the first leg 41 away from the first mounting frame 31 moves towards the side of the second leg 42, thereby realizing the folding and storage of the wearing component 200, and thus reducing the occupied space of the wearing component 200. When the second leg 42 rotates relative to the second mounting frame 32, the end of the second leg 42 away from the second mounting frame 32 moves towards the side away from the first leg 41, thereby unfolding the wearing component 200. For example, in some embodiments, the second leg 42 can be arranged with the structure and connection relationship of the leg main body 411 and the leg side cover 412 in the first leg 41. For the arrangement and function of the second leg 42, reference can be specifically made to the arrangement and function of the first leg 41 in the above embodiments, which will not be elaborated here. Of course, the second leg 42 may not be arranged in the same way as the first leg 41, but may be arranged in other ways, which will not be elaborated here.

[0092] Please refer to Figure 4 and Figure 7 , Figure 7 which discloses Figure 4 the installation structure diagram of the leg main body 411 and the first battery module 413 in the illustrated embodiment. The first battery module 413 is used to store electric energy to provide electric energy for the operation of the head-mounted device 100. The first battery module 413 can be provided with a wireless charging device, for example, wireless charging is carried out by using an electromagnetic induction coil. Of course, the first battery module 413 can also be provided with a wired interface for charging.

[0093] Specifically, the first battery module 413 can be located in the accommodation space 4110 of the first leg 41, such as the first installation space 411a. The first battery module 413 is provided with a first external interface 413a at the installation hole 412a corresponding to the leg side cover 412, so as to facilitate setting the first external interface 413a in the installation hole 412a to realize electrical connection with external devices such as external power supplies, external components 400, and external hosts, and thus can supply power to the external devices. Of course, the external devices can also charge the first battery module 413.

[0094] It can be understood that the second leg 42 can also cooperate with the first battery module 413 according to the cooperation relationship between the first battery module 413 and the first leg 41. Specifically, reference can be made to the first leg 41. Of course, the second leg 42 may not be provided with the first battery module 413.

[0095] Please refer to Figure 4 andFigure 5 The first connection component 414 can be installed on the first leg 41 to be fixedly connected to the external component 400. Specifically, the first connection component 414 can be located within the accommodation space 4110 of the first leg 41. The first connection component 414 can be installed on at least one of the first leg 41 and the second leg 42 to be fixedly connected to the external component 400. Specifically, the first connection component 414 can be installed within the accommodation space 4110. The first connection component 414 can include a first shielding component 415 installed in the second installation space 411b, a second shielding component 416 installed in the second installation space 411c, and a first magnetic member 417 installed in the first installation space 411a. Among them, the first shielding component 415 is used to shield the installation opening 41b, and the second shielding component 416 is used to shield the installation opening 41c. The first magnetic member 417 is used to be fixedly connected to the external component 400.

[0096] It can be understood that names such as "first shielding component", "second shielding component", and "shielding component" can be converted with each other in some embodiments. For example, in one embodiment, the "first shielding component" in other embodiments is referred to as the "second shielding component", and correspondingly, the "second shielding component" in other embodiments is referred to as the "first shielding component".

[0097] The first shielding component 415 can include a contact plate 4151 placed within the second installation space 411b and used to shield the installation opening 41b, and an elastic member 4152 disposed between the installation opening 41b and the leg body 41. Among them, the contact plate 4151 and the elastic member 4152 cooperate to achieve yielding for the external component 400, so that the external component 400 can be installed on the first leg 41, and can also shield the installation opening 41b to improve the appearance expressiveness of the support part 40, such as the first leg 41, when the external component 400 is not installed on the first leg 41.

[0098] The contact plate 4151 can be made of a rigid material, and of course, it can also be made of the same material as the leg body 411 or the leg side cover 412. The contact plate 4151 can be in a plate-like structure, and the contact plate 4151 can slide within the accommodation space 4110, such as the second installation space 411b. The contact plate 4151 can be flush with the outer surfaces of the leg body 411 and the leg side cover 412 at the installation opening 41b to improve the appearance expressiveness of the support part 40, such as the first leg 41. The surface of the contact plate 4151 on one side of the installation opening 41b can be in contact with the leg body 411 and the leg side cover 412 respectively to prevent the contact plate 4151 from sliding out of the accommodation space 4110, such as the second installation space 411b.

[0099] The elastic member 4152 can be a spring. One end of the elastic member 4152 abuts against the abutting plate 4151, and the other end abuts against the leg body 411, so that the abutting plate 4151 abuts against the leg body 411 and the leg side cover 412 under the elastic action of the elastic member 4152, so that the abutting plate 4151 can slide into the accommodation space 4110, such as the second installation space 411b, to expose the installation opening 41b when an external force overcomes the elastic force of the elastic member 4152.

[0100] The second shielding component 416 and the first shielding component 415 can be respectively arranged on both sides of the first magnetic member 417. The second shielding component 416 can shield the installation opening 41c in the same way as the first shielding component 415 to improve the appearance expressiveness of the support part 40, such as the first leg 41, so as to cooperate with the external component 400. For example, in some embodiments, the second shielding component 416 can cooperate with the leg body 411 and the leg side cover 412 in the same way as the first shielding component 415 cooperates with the leg body 411 and the leg side cover 412. For example, in some embodiments, the second shielding component 416 can be arranged in the same structure and connection manner as the abutting plate 4151 and the elastic member 4152 in the first shielding component 415. For the specific arrangement method and function of the second shielding component 416, reference can be made to the arrangement method and function of the first shielding component 415 in the above embodiments, and details will not be repeated. Of course, the second shielding component 416 can also be arranged in a way other than that of the first shielding component 415, and details will not be described.

[0101] It can be understood that at least one of the first shielding component 415 and the second shielding component 416 can be omitted.

[0102] The first magnetic member 417 can generate a magnetic force to connect the external component 400 and realize the installation of the external component 400 on the wearing component 200. The first magnetic member 417 can be a permanent magnet or an electromagnet. When the first magnetic member 417 is an electromagnet, it can be electrically connected to the main body in the head-mounted device 100 to realize the control of the electromagnet.

[0103] The first magnetic member 417 can be installed in the accommodation space 4110, such as the first installation space 411a. In one embodiment, the first magnetic member 417 is specifically located between the leg side cover 412 and the first battery module 413. In one embodiment, the first magnetic member 417 can be arranged on the leg side cover 412.

[0104] It can be understood that the second leg 42 can also be arranged in the same way as the first leg 41 arranges the first connection component 414 to install the external component 400. For the specific arrangement method of the first leg 41 arranging the first connection component 414, reference can be made and details will not be repeated.

Among them, the first and second installation plates 3112, 3113 are opposite and spaced apart to install the first leg 41 between the first and second installation plates 3112, 3113, so that the first installation portion 311 is rotatably connected to the first leg 41, such as the assembly portion 4111. The arrangement direction of the first and second installation plates 3112, 3113 is perpendicular to the arrangement direction of the first and second installation portions 311, 321, so that the first leg 41 rotates relative to the first installation frame 31 to realize the folding storage or unfolding use of the wearing component 200.

[0107] The installation main body 3111 may be hollow inside. In one embodiment, it may facilitate the routing of relevant circuits for the cooperation between the first functional lens 20 and the host. In one embodiment, it may facilitate the optical path arrangement for the cooperation between the first functional lens 20 and the host. In one embodiment, it may facilitate the arrangement of the host for controlling the first functional lens 20.

[0108] Slides 3114 are provided on both the side of the first installation plate 3112 close to the second installation plate 3113 and the side of the second installation plate 3113 close to the first installation plate 3112 to facilitate the cooperation with the tightening adjustment component 50. The slides 3114 of the first installation plate 3112 and the slides 3114 of the second installation plate 3113 both extend to the side away from the second installation portion 321 and extend to the edges of the first and second installation plates 3112, 3113. In one embodiment, the slides 3114 may be omitted.

[0109] Understandably, names such as "first mounting plate", "second mounting plate", and "mounting plate" can be interchanged in some embodiments. For example, in one embodiment, the "first mounting plate" in other embodiments is referred to as the "second mounting plate", and correspondingly, the "second mounting plate" in other embodiments is referred to as the "first mounting plate".

[0110] Limiting grooves 3115 that are recessed inward are provided in the slideways 3114 of the first mounting plate 3112 and the slideways 3114 of the second mounting plate 3113 to cooperate with the first leg 41, such as the fitting portion 4111, so that the fitting portion 4111 slides within the first limiting groove 3115. The extending direction of the limiting groove 3115 can be consistent with the extending direction of the slideway 3114.

[0111] The second mounting portion 321 can be arranged with the second mounting frame 32 in the same way as the first mounting portion 311 and the first mounting frame 31. The second mounting portion 321 can be arranged in the same way as the first mounting portion 311 by providing the mounting body 3111 and the first and second mounting plates 3112, 3113. The second mounting portion 321 can cooperate with the second leg 42 in the same way as the first mounting portion 311 and the first leg 41, so that the first leg 41 rotates relative to the second mounting frame 32 to realize the folding storage or unfolding use of the wearing assembly 200. For the specific arrangement and functions of the second mounting portion 321, reference can be made to the arrangement and functions of the first mounting portion 311 in the above embodiments, and details will not be elaborated here.

[0112] Please refer to together Figure 9 and Figure 12 、 Figure 13 、 Figure 14 。 Figure 12 Disclosed is Figure 9 a schematic structural diagram of the first leg 41 in the embodiment shown in the present application, Figure 13 Disclosed is Figure 12 a partial structural exploded view of the first leg 41 from one perspective in the embodiment shown in the present application, Figure 14 Disclosed is Figure 12 a partial structural exploded view of the first leg 41 from another perspective in the embodiment shown in the present application. Among them, the leg side cover 412 is installed on the side of the leg main body 411 facing the second leg 42. The mounting openings 41b, 41c and the mounting holes 412a can be provided on the leg main body 411.

[0113] The assembly portion 4111 includes a first shaft portion 4113 and a second shaft portion 4114 arranged on the same axis. The axis on which the first shaft portion 4113 and the second shaft portion 4114 are located is the axis on which the first leg 41 rotates relative to the first mounting frame 31. The first shaft portion 4113 can be placed in the limiting groove 3115 of the first mounting plate 3112 and slide in the extending direction of the limiting groove 3115. The second shaft portion 4114 can be placed in the limiting groove 3115 of the second mounting plate 3113 and slide in the extending direction of the limiting groove 3115. At the same time, the assembly portion 4111 can rotate around the first and second shaft portions, and the rotation axis can be the first rotating shaft.

[0114] It is understandable that the names of "first shaft portion", "second shaft portion" and "shaft portion" can be interchanged in some embodiments. For example, in one embodiment, the "first shaft portion" in other embodiments is called the "second shaft portion", and correspondingly, the "second shaft portion" in other embodiments is called the "first shaft portion".

[0115] The assembly portion 4111 further includes a first clamping side wall 4115 extending from the end of the leg body 411 to one side of the first mounting frame 31. The first clamping side wall 4115, the first shaft portion 4113 and the second shaft portion 4114 are surrounded to form an accommodating space 4116 communicating with the accommodating space 4110, and an embedding opening 4115a communicating with the opening 41a is formed to cooperate with the leg side cover 412.

[0116] The first clamping side wall 4115 is provided with a limiting protrusion 4115b on the surface outside the accommodating space 4116 to cooperate with the tension adjustment assembly 50. In one embodiment, the limiting protrusion 4115b can be made of a material with elastic deformation.

[0117] The first clamping side wall 4115 is connected to the leg body 411 to form a clearance portion 4115c to make way for the tension adjustment component 50, so as to enhance the appearance of the wearing body 30. The clearance portion 4115c is stepped.

[0118] The leg side cover 412 may include a side cover main body 4121 covering the opening 41a and a second clamping side wall 4122 extending from the side cover main body 4121 toward the assembly part 4111. The second clamping side wall 4122 covers the embedding opening 4115a and is connected to the first shaft part 4113 and the second shaft part 4114. The end of the second clamping side wall 4122 away from the leg main body 411 may be connected to the end of the first clamping side wall 4115 away from the side cover main body 4121. In an embodiment, the end of the second clamping side wall 4122 away from the leg main body 411 may be spaced from the end of the first clamping side wall 4115 away from the side cover main body 4121, so that the circuit wiring extends from the accommodation space 4116 into the first installation part 311, such as the installation main body 3111. In some embodiments, the optical path may pass through the accommodation space 4116 and enter the first installation part 311 to cooperate with the first functional lens 20, such as the first lens 21.

[0119] It can be understood that, for names such as "the first clamping side wall", "the second clamping side wall", and "the clamping side wall", they can be interchanged in some embodiments. For example, in an embodiment, the "first clamping side wall" in other embodiments is referred to as the "second clamping side wall", and correspondingly, the "second clamping side wall" in other embodiments is referred to as the "first clamping side wall".

[0120] The second leg 42 may be arranged in the same way as the first leg 41, for example, arranging the first shaft part 4113, the second shaft part 4114, the first clamping side wall 4115, the second clamping side wall 4122, the relief part 4115c, the limiting protrusion 4115b, the relief part 4115c, etc. The second leg 42 may cooperate with the second installation frame 32 in the same cooperation relationship as the first leg 41 and the first installation frame 31. The second leg 42 may cooperate with the external hanging component 400 in the same cooperation relationship as the first leg 41 and the external hanging component 400. The second leg 42 may cooperate with the first functional lens 20, such as the second lens 22, in the same cooperation relationship as the first leg 41 and the first functional lens 20. For the specific arrangement and functions of the components in the second leg 42, reference may be made to the arrangement and functions of the first leg 41, which will not be elaborated here.

[0121] Please refer to Figure 9 、 Figure 15 、 Figure 16 、 Figure 17 and Figure 18 , Figure 15 which discloses Figure 9 a schematic structural diagram of the tension adjustment assembly 50 in the embodiment shown in the present application, Figure 16 which discloses Figure 9 a schematic structural diagram of a perspective view when the wearing main body 30 is connected to the tension adjustment assembly 50 in the embodiment shown in the present application, Figure 17 which discloses Figure 9A schematic structural view from another perspective when the wearing body 30 is connected to the tension adjustment assembly 50 in the illustrated embodiment. Figure 18 The present application is disclosed Figure 9 A schematic structural view of the first leg connected to the first adjusting member 51 in the illustrated embodiment. The tension adjustment assembly 50 may include a first adjusting member 51 installed in the first mounting frame 31 and connected to the first leg 41, such as the fitting portion 4111, and a second adjusting member 52 installed on the second mounting frame 32 and connected to the second leg 42, such as the fitting portion 4111. Among them, the first adjusting member 51 is used to adjust the force between the first leg 41 and the user's head, and the second adjusting member 52 is used to adjust the force between the second leg 42 and the user's head.

[0122] It can be understood that names such as "first adjusting member", "second adjusting member", and "adjusting member" can be interchanged in some embodiments. For example, in one embodiment, the "first adjusting member" in other embodiments is referred to as the "second adjusting member", and correspondingly, the "second adjusting member" in other embodiments is referred to as the "first adjusting member".

[0123] The first adjusting member 51 is made of a material with elastic deformation. The first adjusting member 51 may include a connecting portion 511 provided on opposite sides of the first mounting portion 311 and the first mounting frame 31 respectively, and a bending portion 512 connected and fixed to the connecting portion 511. Among them, the bending portion 512 is provided at a position corresponding to the first mounting portion 311 of the connecting portion 511. The bending portion 512 extends from the edge of the connecting portion 511 and bends toward the first mounting portion 311. The bending portion 512 may be provided on a side of the first mounting portion 311 away from the second mounting portion 321. In one embodiment, the bending portion 512 may abut against a side of the first mounting portion 311 away from the second mounting portion 321.

[0124] The shape of the connecting portion 511 may be the same as the shape of the first mounting frame 31, for example, it may be in a ring structure, of course, it may also be in a semi-ring structure, or it may be in other shaped structures, such as a shape with texture or pattern on the surface. The connecting portion 511 may surround the first lens 21. In one embodiment, the edge portion of the connecting portion 511 at the first lens 21 may be provided on a side of the first lens 21 away from the first mounting frame 31 so as to sandwich the first lens 21 between the edge portion and the first mounting frame 31.

[0125] It can be understood that the connecting portion 511 can realize the connection between the bending portion 512 and the first mounting frame 31, so the connecting portion 511 can be omitted, and the end of the bending portion 512 can be fixed on the first mounting frame 31. In one embodiment, the end of the bending portion 512 can be fixed on the first mounting portion 311.

[0126] The bending portion 512 is provided with a first pivoting portion 5122 and a second pivoting portion 5123 which are arranged opposite to each other at a position opposite to the slideway 3114. The first pivoting portion 5122 can be placed in the slideway 3114 of the first mounting plate 3112 and slide in the extension direction of the slideway 3114. The first pivoting portion 5122 can be rotatably connected to the first shaft portion 4113. The second pivoting portion 5123 can be placed in the slideway 3114 of the second mounting plate 3113 and slide in the extension direction of the slideway 3114. The second pivoting portion 5123 can be rotatably connected to the second shaft portion 4114.

[0127] It is understandable that the names of "first pivoting portion", "second pivoting portion" and "pivoting portion" can be interchanged in some embodiments. For example, in one embodiment, the "first pivoting portion" in other embodiments is called the "second pivoting portion", and correspondingly, the "second pivoting portion" in other embodiments is called the "first pivoting portion".

[0128] When the first leg 41 rotates, the bending portion 512 can be located at the yielding portion 4115c, and when the bending portion 512 abuts against the first leg 41, such as the leg body 411 and the first clamping side wall 4115, the bending portion 512 and the first leg 41 are relatively stationary. In one embodiment, when the bending portion 512 abuts against the first leg 41, such as the leg body 411 and the first clamping side wall 4115, the bending portion 512 can be flush with the outer surface of the first leg 41, such as the leg body 411, so as to improve the appearance of the wearing assembly 200.

[0129] In one embodiment, when the first leg 41 rotates relative to the bending portion 512, it can rotate to a position where the limiting protrusion 4115b abuts against the bending portion 512, and the limiting protrusion 4115b is squeezed and deformed to increase the damping when the first leg 41 rotates relative to the bending portion 512, thereby improving the user's folding, storage, and unfolding feel. For example, when the first leg 41 rotates relative to the bending portion 512 to achieve the folding of the wearing component 200, the limiting protrusion 4115b abuts against the bending portion 512, so that the folding process needs to overcome the friction between the limiting protrusion 4115b and the bending portion 512. For example, when the first leg 41 rotates relative to the bending portion 512 to achieve the unfolding of the wearing component 200, the limiting protrusion 4115b abuts against the bending portion 512, so that the unfolding process needs to overcome the friction between the limiting protrusion 4115b and the bending portion 512. Of course, the number and position of the limiting protrusions 4115b can increase the damping effect when the first leg 41 rotates relative to the bending portion 512 and rotates to a certain position or a certain section of the rotation stroke.

[0130] Of course, when the limiting protrusion 4115b is not elastic, it can have a limiting effect when it abuts against the bending portion 512, so that the first leg 41 is stationary relative to the bending portion 512.

[0131] The second adjusting member 52 can be arranged in the same manner as the first adjusting member 51. The second adjusting member 52 can be arranged in the same manner as the first adjusting member 51, the first mounting frame 31, the first lens 21 and the first leg 41, and in the second mounting frame 32, the second lens 22 and the second leg 42. The structure, connection method and function of each component in the second adjusting member 52 can refer to the first adjusting member 51, and will not be described in detail.

[0132] The process of adjusting the support portion 40 by the tension adjustment assembly 50 is as follows:

[0133] The first leg 41 and the second leg 42 rotate relative to the wearing body 30 for unfolding and use. The first leg 41 rotates relative to the first pivoting portion 5122 and rotates toward the side away from the second leg 42. The second leg 42 rotates relative to the second pivoting portion 5123 and rotates toward the side away from the first leg 41. When the bending portion 512 is rotated to be located at the yielding portion 4115c and abuts against the leg body 411 and the first clamping side wall 4115, the first leg 41 and the second leg 42 can still be unfolded, but the first leg 41 is stationary relative to the first pivoting portion 5122, and the second leg 42 is stationary relative to the second pivoting portion 5123, so that the first shaft portion 4113 in the first leg 41 and the second leg 42 slides in the limiting groove 3115 of the first mounting plate 3112, and the second shaft portion 4114 slides in the limiting groove 3115 of the second mounting plate 3113. 122 slides in the slideway 3114 of the first mounting plate 3112, and the second pivoting portion 5123 slides in the slideway 3114 of the second mounting plate 3113, so that the first leg 41 and the first pivoting portion 5122 rotate together around a second rotation axis, and the second leg 42 and the second pivoting portion 5123 rotate together around another second rotation axis. At the same time, the bending portion 512 bends to the side away from the first and second mounting portions 311 and 321, so that the bending portion 512 undergoes elastic deformation, so that the bending portion 512 has a force to restore the original state under the action of elastic deformation. That is, the first leg 41 has a force to move toward the second leg 42 side, and the second leg 42 has a force to move toward the first leg 41 side. When wearing, the size of the head mounted device 100 can be easily adjusted to make it easy to wear. Under the force of the bending portion 512 to restore the original state, the forces of the first leg 41 and the second leg 42 on the user's head are adjustable, so that it is comfortable to wear.

[0134] The first leg 41 and the second leg 42 rotate relative to the wearing body 30 for folding and storage. The acting force for the bent portion 512 to return to its original state causes the first leg 41 to move towards the second leg 42, and the second leg 42 to move towards the first leg 41. This causes the first leg 41 and the first pivoting portion 5122 to rotate together about a second rotation axis, and the second leg 42 and the second pivoting portion 5123 to rotate together about another second rotation axis. As a result, the first shaft portion 4113 in the first leg 41 and the second leg 42 slides within the limit slot 3115 of the first mounting plate 3112, and the second shaft portion 4114 slides within the limit slot 3115 of the second mounting plate 3113.

[0160] Please refer to Figure 19 , the structure and setting method of the second functional lens 60 can be designed according to the structure and setting method of the first functional lens 20. Of course, the function of the second functional lens 60 can be different from or the same as that of the first functional lens 20. For the structure, setting method, and function of the second functional lens 60, please specifically refer to the first functional lens 20 in the above embodiments.

[0161] In one embodiment, the second functional lens 60 can be an optical waveguide, specifically a planar grating waveguide such as a diffraction grating waveguide. The head-mounted device 100 can present a virtual reality / augmented reality environment through the second functional lens 60.

[0162] Taking the second functional lens 60 as an optical waveguide as an example, the second functional lens 60 will be introduced below.

[0163] The second functional lens 60 can be provided with an optical coupling inlet and an optical coupling outlet. The optical coupling inlet and the optical coupling outlet are connected together to form an optical path. Light is coupled into the lens from the optical coupling inlet, transmitted within the optical path, and finally the light will be coupled out of the lens at the optical coupling outlet, and then enter the wearer's eyes and form an image on the retina.

[0164] In one embodiment, please refer to Figure 21 and Figure 22 、 Figure 23 , Figure 21 discloses another structural schematic diagram of the connection between the second functional lens 60 and the third mounting frame 83 in the embodiment shown in Figure 19 of the present application, Figure 22 discloses an exploded view of the connection between the second functional lens 60 and the third mounting frame 83 in the embodiment shown in Figure 21 of the present application, Figure 23 discloses a cross-sectional view of the connection between the second functional lens 60 and the third mounting frame 83 along line XXI-XXI in the embodiment shown in Figure 21 of the present application. The second functional lens 60 can include a first protective lens 61 with a protective space 610 provided inside, an optical waveguide lens 62 disposed in the protective space 610, and a second protective lens 63 that is snap-fitted with the first protective lens 61 to form the protective space 610.

[0165] It is understandable that the names of "first protective lens", "second protective lens" and "protective lens" can be interchanged in some embodiments. For example, in one embodiment, the "first protective lens" in other embodiments is called "second protective lens", and correspondingly, the "second protective lens" in other embodiments is called "first protective lens".

[0166] The first protective lens 61 can be made of a material with high pressure resistance and impact resistance such as plastic. The first protective lens 61 can include a lens body 611 stacked with the optical waveguide lens 62 and a side wall 612 formed at the edge of the lens body 611 and surrounding the optical waveguide lens 62. Among them, the lens body 611 is a plate-like structure. The side wall 612 extends to one side of the second protective lens 63 so that the lens body 611 and the side wall 612 are surrounded to form a protective space 610. A first plug-in structure 613 can be provided at one end of the side wall 612 close to the second protective lens 63 to cooperate with the second protective lens 63. In one embodiment, the first plug-in structure 613 can be a plug-in slot.

[0167] In one embodiment, the side wall 612 is provided with a stepped support platform 614 in the protection space 610 to cooperate with the optical waveguide lens 62 so that the optical waveguide lens 62 and the first protection lens 61 , such as the lens body 611 , are spaced apart.

[0168] The optical waveguide lens 62 may be a planar grating waveguide such as a diffraction grating waveguide. The optical waveguide lens 62 may be provided with an optical coupling inlet portion and an optical coupling outlet portion. The optical coupling inlet portion and the optical coupling outlet portion are connected together to form an optical path, and light is coupled into the lens from the optical coupling inlet portion, transmitted in the optical path, and finally the light is coupled out of the lens at the optical coupling outlet portion, emitted into the wearer's eyes and imaged on the retina.

[0169] The optical waveguide lens 62 may be disposed on the support platform 614 so that the optical waveguide lens 62 is spaced apart from the lens body 611. That is, the optical waveguide lens 62 may be engaged with the first protective lens 61 to form the first sub-protection space 610a.

[0170] In one embodiment, the optical waveguide lens 62 can be fixed on the support platform 614 by a fixing member 621. In one embodiment, the fixing member 621 can be a plastic frame to surround the edge of the optical waveguide lens 62. In one embodiment, the plastic frame is foam glue. Of course, the fixing member 621 can also be other structures such as plug-in, buckle and other structures.

[0171] Of course, when the fixing member 621 can make the optical waveguide lens 62 and the support platform 614 spaced apart, the support platform 614 can be omitted, so that the optical waveguide lens 62 is directly fixed on the lens body 611 through the fixing member 621, thereby making the optical waveguide lens 62 and the lens body 611 spaced apart.

[0172] In one embodiment, when the optical waveguide lens 62 is fixed on the support platform 614 or other positions, it may not be in direct contact with the first protective lens 61, such as the side wall 612, so as to avoid the extrusion of the optical waveguide lens 62 caused by the force on the side wall 612.

[0173] The second protective lens 63 can be made of the same material as the first protective lens 61. A second plugging structure 631 can be provided at the edge of the second protective lens 63 so as to be plugged and fixed with the first plugging structure 613, realizing the snap connection between the first protective lens 61 and the second protective lens 63. In one embodiment, the second plugging structure 631 can be a protrusion. Of course, in one embodiment, the second protective lens 63 and the first protective lens 61 can also be fixed by means such as bonding. In one embodiment, glue can also be applied in the first plugging structure 613, such as the plugging groove, and then the second plugging structure 631 is plugged with the first plugging structure 613 to realize the snap connection between the first protective lens 61 and the second protective lens 63, and the glue can be further bonded and fixed to enhance the connection strength between the first protective lens 61 and the second protective lens 63. In addition, the first protective lens 61 and the second protective lens 63 can form a closed protective space 610 to achieve the effects of waterproofing and dustproofing and improve the compressive capacity of the optical waveguide lens 62.

[0174] In one embodiment, the optical waveguide lens 62 and the second protective lens 63 are arranged at intervals, that is, the arrangement of the optical waveguide lens 62 divides the protective space 610 into two sub-spaces, namely the first sub-protective space 610a and the second sub-protective space 610b located on the side of the optical waveguide lens 62 close to the second protective lens 63, so as to avoid the extrusion of the optical waveguide lens 62 caused by the force on the side wall 612.

[0175] In one embodiment, the optical waveguide lens 62 abuts against the second protective lens 63.

[0176] In one embodiment, please refer to Figure 23 , the first lens holder 811 of the third mounting frame 83 can be omitted. The second lens holder 821 is directly connected and fixed to the second functional lens 60. The second lens holder 821 can be provided with a glue application groove 8211 on the side that fits with the second protective lens 63, such as the second protective lens 63, so as to apply glue in the glue application groove 8211 to realize the bonding and fixing between the second protective lens 63 and the second lens holder 821. Of course, the second lens holder 821 and the second protective lens 63 can also be fixed by other means, which will not be elaborated.

[0177] In one embodiment, the second lens holder 821 is provided with a light passing hole 8212 on the side close to the wearing component 200 and at a position corresponding to the optical waveguide lens 62, such as the optical coupling inlet part, so as to cooperate with the host 90 to form an optical path for light to be coupled into the optical waveguide lens 62.

[0178] Understandably, the optical waveguide lens 62 is sandwiched between the first protective lens 61 and the second protective lens 63, forming a 360° all-round enclosure for the optical waveguide lens 62, which can protect the optical waveguide lens 62. In addition, the setting of the protection space 610 increases the redundant space for the first protective lens 61 and the second protective lens 63 to deform under force, ensuring that when the second functional lens 60 is stressed, the deformation of the optical waveguide lens 62 is reduced. In addition, combined with the fixing member 621 such as foam adhesive, etc., a flexible connection between the optical waveguide lens 62 and the first protective lens 61 is achieved, which can further reduce the deformation of the optical waveguide lens 62 under force, achieving the purpose of protecting the optical waveguide lens 62 and making the overall compressive strength of the second functional lens 60 better.

[0179] The second functional lens 60 provides compressive, impact-resistant and dust-proof protection for the optical waveguide lens 62 through its unique structure, is lighter in weight and thinner in thickness than the existing solutions. The second functional lens 60 can be made to have a size similar to that of a common lens, and its shape can be diversified, which is of great help to improving the expressiveness and reliability of the head-mounted device 100 using the second functional lens 60. The structure of this solution is simple to assemble, has a low cost, and is suitable for mass production.

[0180] Understandably, the second functional lens 60 and the first functional lens 20 also play various light-transmitting special effects. Therefore, the first lens 21 and the second lens 22 in the first functional lens 20 can both be arranged in the design manner of the second functional lens 60. Similarly, the first mounting frame 31 and the second mounting frame 32 can also both be arranged in the design manner of the third mounting frame 83. Details are not elaborated here.

For example, when the host 90 is entirely disposed within the support portion 40, the second functional lens 60 may not cooperate with the host 90. For example, a part of the host 90 is within the first leg 41 and another part is disposed within the second leg 42. For example, a part of the host 90 is within the support portion 40 and another part is disposed within the housing body 84.

[0201] Understandably, the second leg 42 may also cooperate with the first battery module 413 in accordance with the cooperation relationship between the first battery module 413 and the first leg 41. For details, reference may be made to the first leg 41. Of course, the first battery module 413 may not be installed on the second leg 42.

[0202] Furthermore, when the various electronic components in the host 90 are distributed between the wearing component 200 and the external attachment component 400, the electrical connection and communication of the various electronic components within the host 90 may be achieved under the control of the main board 92 through the first external interface 413a and the second external interface 9413, that is, the first external interface 413a and the second external interface 9413 do not merely have the function of powering the head-mounted device 100 by the battery module.

[0203] Please refer again to Figure 19 , the second connection component 71 is disposed on the housing body 84 and is used to cooperate with the first connection component 414. The second connection component 71 may include a second magnetic member 711 disposed in the storage space 812a and a clamping member 712 disposed on the housing body 84, such as the second sub-housing 822. The second magnetic member 711 can generate a magnetic force to connect the support portion 40, such as the first leg 41, to achieve the installation of the external attachment component 400 on the wearing component 200. The second magnetic member 711 may be a permanent magnet or an electromagnet. When the second magnetic member 711 is an electromagnet, it may be electrically connected to the host 90 within the head-mounted device 100 to achieve the control of the electromagnet. In one embodiment, the second magnetic member 711 may be located between the host 90 and the second sub-housing 822. In one embodiment, the second magnetic member 711 may be disposed on the second sub-housing 822.

[0204] Understandably, names such as "first magnetic member", "second magnetic member", and "magnetic member" can be converted into each other in some embodiments. For example, in one embodiment, the "first magnetic member" in other embodiments is referred to as the "second magnetic member", and correspondingly, the "second magnetic member" in other embodiments is referred to as the "first magnetic member".

[0205] The second magnetic member 711 can generate a magnetic attraction force with the first electromagnetic member 414 to realize the installation of the external component 400 on the wearing component 200.

[0206] The clamping member 712 is arranged on the side of the second sub-shell 822 away from the first sub-shell 812 and is located on opposite sides of the second magnetic member 711. Specifically, the clamping member 712 is arranged relative to the mounting openings 41b, 41c so that the clamping member 712 can be inserted into the mounting openings 41b, 41c to realize the positioning of the external component 400 and the wearing component 200. In one embodiment, when the clamping member 712 is inserted into the mounting openings 41b, 41c, it can be clamped or plugged with the first leg 41, which will not be elaborated here.

[0207] Please refer to Figure 28 , Figure 28 which discloses a schematic structural diagram of the head-mounted device 100 in another embodiment of the present application. Two external components 400 can be arranged in the head-mounted device 100, one of which is arranged on the first leg 41 and the other is arranged on the second leg 42. Understandably, only one external component 400 can also be arranged in the head-mounted device 100. The external component 400 can be installed on the first leg 41 through the connection of the first connection component 414 and the second connection component 71, or the external component 400 can be rotated 180° and installed on the second leg 42 through the connection of the first connection component 414 and the second connection component 71.

[0208] The present application adopts the design method of the external component 400 to solve the problem of heaviness when wearing smart glasses. The present application ensures both the virtual reality / augmented reality experience function and the sunglasses function brought by the electrochromic / photochromic device through the external component 400. At the same time, the first battery module can be used as a backup power source to provide part of the electric energy for the external component 400, increasing the battery life of the virtual reality / augmented reality experience and providing an extreme experience for consumers.

[0209] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structural or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
