[0049] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0050] The present application describes 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 also be other devices that need to be worn on the user's head, such as glasses, or devices that have other functions such as lighting and can be worn on the user's head, which will not be described in detail. The following is a detailed description using augmented reality or virtual reality glasses as an example.

[0051] In the example of augmented reality or virtual reality glasses, the head-mounted device can be configured to pass data to and receive data from an external processing device via a signal connection, and the signal connection can be a wired connection, a wireless connection, or a combination thereof. However, in other cases, the head-mounted device can be used as a standalone device, that is, data processing is performed on the head-mounted device itself. The signal connection can 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 can be, for example, a game console, a personal computer, a tablet computer, a smart phone, or other type of processing device. The signal connection can 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), a wide area network (WAN), an intranet, a metropolitan area network (MAN), the global Internet, or a combination thereof.

[0052] The head mounted device may be equipped with a display assembly, optical devices, sensors, processors, etc. In the example of augmented reality or virtual reality glasses, the display assembly is designed to, for example, implement the functions of virtual reality glasses by projecting light into the user's eyes, for example, by projecting light into the user's eyes and overlaying images on the user's view of their real world environment to implement the functions of augmented reality glasses. The head mounted device may also include sensors such as ambient light sensors, Hall sensors, etc., and may also include electronic circuit systems to control at least some of the above components and perform associated data processing functions. The electronic circuit system may include, for example, one or more processors and one or more memories.

It is understandable that the frame structure 10 may not be limited to the wearing body 40 and the support portion 50, and it may also include other structures, which will not be elaborated.

[0058] See also Figure 3 and Figure 4 , Figure 4 For this application Figure 3 A schematic diagram of the structure of the wearing body 40 in the illustrated embodiment. The wearing body 40 may include a first shell 41 connected to a support portion 50 on one side, a shielding member 42 disposed on the first shell 41 away from the support portion 50, a first connecting member 43 mounted on the first shell 41, an assembly frame 44 disposed on the first shell 41 away from the support portion 50, and a nose pad 45 mounted on the assembly frame 44. Among them, the first shell 41 can cooperate with the assembly frame 44 to install and fix the first functional lens module 20. The first shell 41 can be connected and fixed to the assembly frame 44 through the first connecting member 43. The first shell 41 can be used to cooperate with the first circuit system 30. The shielding member 42 can be used to shield the first circuit system 30 disposed on the first shell 41 to enhance the appearance of the wearing body 40. The nose pad 45 can be used to support the wearing body 40 when the wearing body 40 is worn on the bridge of the user's nose.

[0059] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 , Figure 5 For this application Figure 4 The schematic structural diagram of the first housing 41 from one perspective in the embodiment shown, Figure 6 For this application Figure 4 A schematic structural diagram of the first housing 41 from another perspective in the embodiment shown, Figure 7 For this application Figure 4A schematic diagram of the structure of the first housing 41 from another perspective in the illustrated embodiment. The material of the first housing 41 may be a hard material. The first housing 41 may include a channel housing 411 for cooperating with the first circuit system 30, a mounting frame 412 provided on one side of the channel housing 411 and snap-connected with the assembly frame 44, and a connecting arm 413 connected to the channel housing 411 and respectively provided on both sides of the channel housing 411 and both sides of the mounting frame 412. Wherein, the channel housing 411 and the mounting frame 412 may both be located on the same side of the assembly frame 44. The mounting frame 412 cooperates with the assembly frame 44 to clamp and fix the first functional lens module 20. The connecting arm 413 is used to connect with the support portion 50 to achieve the connection between the first housing 41 and the support portion 50.

[0060] The channel shell 411 can be generally in the form of a strip plate structure. A shielding member 42 and an assembly frame 44 can be sequentially covered on the side of the channel shell 411 away from the support portion 50. The channel shell 411 can include a strip-shaped body 4111 and a first flange 4112 and a second flange 4113 bent from two long edges in the extension direction of the body 4111 toward one side of the shielding member 42. The body 4111, the first flange 4112 and the second flange 4113 are arranged to form a wiring channel 41a to arrange the first circuit system 30. The shielding member 42 is used to shield the first circuit system 30 arranged in the wiring channel 41a. The first flange 4112 is located on the side of the body 4111 away from the installation frame 412, and the second flange 4113 is located on the side of the body 4111 close to the installation frame 412. The first convex edge 4112 and the second convex edge 4113 extend in the direction extending from the long side edge of the body 4111 and extend to the position where the first convex edge 4112 and the second convex edge 4113 are connected. It can be understood that the first convex edge 4112 and the second convex edge 4113 can also be connected together through the convex edge of the short side edge of the body 4111. In other embodiments, the first convex edge 4112 and the second convex edge 4113 can also be part of or all of the convex edge extending to one side from the edge of the body 4111.

[0061] It is understandable that the names of "first convex edge", "second convex edge" and "convex edge" can be interchanged in some embodiments. For example, in one embodiment, the "first convex edge" in other embodiments is called the "second convex edge", and correspondingly, the "second convex edge" in other embodiments is called the "first convex edge".

[0062] The middle part of the main body 4111 can be recessed toward one side of the shielding member 42 to form a clearance portion, such as a first clearance portion 41b, to make room for the user's nose bridge. In one embodiment, the first clearance portion 41b can be omitted.

[0063] The main body 4111 may have two ends in the extension direction with connecting holes 41c to cooperate with the first circuit system 30. In one embodiment, the main body 4111 may have a connecting hole 41c only at one end of the main body 4111 in the extension direction.

[0064] The first flange 4112 may extend from the edge of the body 4111 to one side of the assembly frame 44. In one embodiment, the first flange 4112 is provided with first mounting portions 4114 on both sides of the first clearance portion 41b for mounting the first connector 43. In one embodiment, the first mounting portion 4114 may be a groove. The groove may be recessed inwardly from the surface of the first flange 4112 near the second flange 4113.

[0065] In some embodiments, the first mounting portion 4114 may be disposed only on one side of the first clearance portion 41b. In some embodiments, the position of the first flange 4112 corresponding to the first clearance portion 41b may be flush with the surface of the body 4111. In some embodiments, the first flange 4112 may be flush with the surface of the body 4111 at one side of the first clearance portion 41b and at a position where the first mounting portion 4114 is not disposed.

[0066] The second protrusion 4113 extends from the edge of the body 4111 toward one side of the assembly frame 44 .

[0067] The second convex edge 4113 may include a first sub-convex edge 4113a opposite to the first conceding portion 41b and second sub-convex edges 4113b located on both sides of the first sub-convex edge 4113a, wherein the first sub-convex edge 4113a is connected to the second sub-convex edge 4113b.

[0068] It is understandable that the names of "first sub-ridge", "second sub-ridge" and "sub-ridge" can be interchanged in some embodiments. For example, in one embodiment, the "first sub-ridge" in other embodiments is called the "second sub-ridge", and correspondingly, the "second sub-ridge" in other embodiments is called the "first sub-ridge".

[0069] In one embodiment, the extension length of the first sub-convex edge 4113a extending from the edge of the body 4111 to the side of the assembly frame 44 is the same as the extension length of the first convex edge 4112 extending from the edge of the body 4111 to the side of the assembly frame 44, so as to improve the appearance. In some embodiments, when the position corresponding to the first convex edge 4112 and the first yielding portion 41b can be flush with the surface of the body 4111, the first sub-convex edge 4113a is flush with the surface of the body 4111.

[0070] In one embodiment, the extension length of the second sub-convex edge 4113b extending from the edge of the body 4111 to the side of the assembly frame 44 is shorter than the extension length of the first convex edge 4112 extending from the edge of the body 4111 to the side of the assembly frame 44, so as to make way for the assembly frame 44. It can be understood that the extension length of the second sub-convex edge 4113b extending from the edge of the body 4111 to the side of the assembly frame 44 can also be the same as the extension length of the first convex edge 4112 extending from the edge of the body 4111 to the side of the assembly frame 44. In some embodiments, when the first convex edge 4112 is flush with the surface of the body 4111 at one side of the first making way portion 41b and at a location where the first mounting portion 4114 is not provided, the second sub-convex edge 4113b opposite to the first convex edge 4112 at one side of the first making way portion 41b and at a location where the first mounting portion 4114 is not provided can be flush with the surface of the body 4111.

[0071] The second sub-convex edge 4113b is provided with a second mounting portion 4115 to cooperate with the first functional lens module 20. In one embodiment, the second mounting portion 4115 may be a groove. The groove may be recessed inwardly from the surface of the second sub-convex edge 4113b close to the first convex edge 4112.

[0072] See also Figure 5 , Figure 6 and Figure 7 , the number of the mounting frames 412 may include two, namely, a first mounting frame 412a and a second mounting frame 412b. The first mounting frame 412a and the second mounting frame 412b are symmetrical and spaced apart. The gap between the first mounting frame 412a and the second mounting frame 412b can make way for a human body, such as a nose bridge, so that the nose pad 45 can be installed between the first mounting frame 412a and the second mounting frame 412b. In one embodiment, one of the first mounting frame 412a and the second mounting frame 412b can be omitted.

[0073] The mounting frame 412, such as the first mounting frame 412a and the second mounting frame 412b, may include a mounting frame body 4121 extending from the second sub-convex edge 4113b to a side away from the first convex edge 4112. It can be understood that the second sub-convex edge 4113b can be omitted, and the mounting frame body 4121 can be extended from the position where the body 4111 is opposite to the second sub-convex edge 4113b to a side away from the first convex edge 4112.

[0074] A light-transmitting hole 4122 is provided in the middle of the mounting frame body 4121, so that the mounting frame body 4121 is annular in structure, and the light-transmitting hole 4122 is used to cooperate with the first functional lens module 20. In one embodiment, the light-transmitting hole 4122 can be extended to the edge of the mounting frame body 4121, so that the mounting frame body 4121 is a semi-annular in structure.

[0075] The edge of the mounting frame body 4121 is provided with a third protrusion 4123 to cooperate with the first connector 43 and / or the first functional lens module 20. The third protrusion 4123 is bent from the edge of the mounting frame body 4121 to one side of the assembly frame 44.

[0076] One of the two ends of the third flange 4123 formed by the disconnection of the edge where the mounting frame body 4121 is connected to the second sub-flange 4113b can be connected to one end of the first flange 4112, and the other end can be connected to one end of the first sub-flange 4113a. In one embodiment, the surface of the third flange 4123 away from the mounting frame body 4121 can be flush with the surface of the third flange 4123 away from the body 4111. In one embodiment, the surface of the third flange 4123 away from the mounting frame body 4121 can be flush with the surface of the first sub-flange 4113a away from the body 4111. In one embodiment, one end of the third flange 4123 can be simultaneously connected to one end of the first sub-flange 4113a and one end of the second sub-flange 4113b connected to the first sub-flange 4113a.

[0077] The third flange 4123 is provided with a first mounting portion 4124, and the first mounting portion 4124 cooperates with the first mounting portion 4114 on the first flange 4112 to mount the first connector 43. In one embodiment, the first mounting portion 4124 may be a groove. The groove may be recessed inward from the surface of the third flange 4123 near the light-transmitting hole 4122. In one embodiment, one of the first mounting frame 412a and the second mounting frame 412b may not be provided with the first mounting portion 4124.

[0078] See also Figure 7 The first mounting frame 412a is provided with a connecting portion 412c on one side close to the second mounting frame 412b and the second mounting frame 412b is provided with a connecting portion 412c on one side close to the first mounting frame 412a for mounting the nose pad 45. In one embodiment, the connecting portion 412c may be a groove. The groove may be recessed inward from the surface of the third convex edge 4123 away from the light transmission hole 4122. In one embodiment, one of the first mounting frame 412a and the second mounting frame 412b may not be provided with the connecting portion 412c.

[0079] The number of the connecting arms 413 may include two, namely, the first connecting arm 413a and the second connecting arm 413b. The first connecting arm 413a and the second connecting arm 413b may be respectively located at the two end portions of the channel shell 411, such as the body 4111, in the extension direction. The first connecting arm 413a and the second connecting arm 413b may be located on the same side of the channel shell 411, such as the body 4111, close to the support portion 50. In some embodiments, the installation position of the first connecting arm 413a and the second connecting arm 413b may also be installed on the installation frame body 4121. Of course, the installation position of the first connecting arm 413a and the second connecting arm 413b may also be other, as long as the first connecting arm 413a and the second connecting arm 413b are symmetrically arranged and can be used to connect with the support portion 50. In some embodiments, the first connecting arm 413a and the second connecting arm 413b may be omitted. The channel shell 411 or the installation frame 412 is directly connected to the support portion 50.

[0080] The connecting arm 413, such as the first connecting arm 413a and the second connecting arm 413b, may include a fixing space 41d ( Figure 6 The connecting arm body 4131 (shown in FIG. 4 ) and the first and second mounting plates 4132 and 4133 disposed at one end of the connecting arm body 4131 away from the channel shell 411, such as the body 4111. The first and second mounting plates 4132 and 4133 are used to connect with the support portion 50.

The isolation cover 5522 may have an opening on the side away from the leg body 53, that is, on the side close to the first decorative sheet 553, so that the magnet 5521 is exposed toward the side of the first decorative sheet 553 and is connected to the external device 400 by magnetic force. The isolation cover 5522 is used to isolate or weaken the magnetic force of the first magnet member 552 on the side of the leg body 53, so that the magnetic interference of the first magnet member 552 on the first circuit system 30 is weakened or eliminated, thereby protecting the first circuit system 30. In one embodiment, the isolation cover 5522 may be omitted.

[0138] The first decorative sheet 553 can be made of a hard material or a flexible material. The first decorative sheet 553 can be used to shield the first magnet 552 to improve the appearance. In one embodiment, the first decorative sheet 553 is provided with a fourth mounting hole 5531 corresponding to the position of the third mounting hole 5512 to cooperate with the first circuit system 30.

[0139] It can be understood that the first mounting component 55 may not be connected to the external device 400 through the first magnet component 552, and the connection and fixation can be achieved through a plug-in structure, a snap-on structure, a screw structure, etc., which will not be elaborated.

[0140] In addition, the names of "first mounting hole", "second mounting hole", "third mounting hole", "fourth mounting hole" and "mounting hole" can be interchanged in some embodiments. For example, in one embodiment, the "first mounting hole" in other embodiments is called the "second mounting hole", and correspondingly, the "second mounting hole" in other embodiments is called the "first mounting hole".

[0141] See also Fig.10 The leg side cover 54 can be made of a hard material or a flexible material. Of course, the same material as the leg body 53 can also be used. The leg side cover 54 can be buckled on the side of the leg body 53 facing the second leg 52. The leg side cover 54 can include a side cover body 541 covering the leg body 53 and an abutting side wall 542 extending from the side cover body 541 to one side of the assembly part 533 and abutting or buckling with the assembly part body 534. Among them, the first circuit system 30 can be arranged between the abutting side wall 542 and the assembly part body 534 for cooperation.

[0142] In one embodiment, the side cover body 541 is provided with a clearance notch 5411 for the recessed portion 53b of the bent portion 531. In one embodiment, the side cover body 541 cooperates with the bent portion 531 to fasten the first and second clamping portions 5321 and 5322 of the decorative element 532.

[0143] The second leg 52 is symmetrically arranged with the first leg 51 so that the second leg 52 cooperates with the first leg 51 to realize that the wearable device 200 is worn on the user's head. The second leg 52 can be arranged in the manner of the first leg 51 described above. For example, in some embodiments, the second leg 52 can be connected to the second connecting arm 413b in the manner of the first leg 51 being connected to the first connecting arm 413a. When the first leg 51 rotates relative to the first connecting arm 413a, the end of the first leg 51 away from the first connecting arm 413a moves toward the side of the second leg 52, thereby realizing the folding and storage of the wearable device 200, thereby reducing the occupied space of the wearable device 200. When the second leg 52 rotates relative to the second connecting arm 413b, the end of the second leg 52 away from the second connecting arm 413b moves toward the side away from the first leg 51, thereby unfolding the wearable device 200. For example, in some embodiments, the second leg 52 may be arranged in the same manner as the leg body 53 and the leg side cover 54 in the first leg 51. The arrangement and function of the second leg 52 may refer to the arrangement and function of the first leg 51 in the above embodiment, and will not be described in detail. Of course, the second leg 52 may also be arranged in other ways instead of the arrangement of the first leg 51, and will not be described in detail.

[0144] In one embodiment, the first leg 51 and the second leg 52 can be integrated with the first shell 41 .

[0145] In some embodiments, the first leg 51 is rotatably connected to the first connecting arm 413a of the first housing 41, such as the first mounting plate 4132 and the second mounting plate 4133, through the assembly part 533, such as the shaft assembly 535, and the second leg 52 is rotatably connected to the second connecting arm 413b of the first housing 41, such as the first mounting plate 4132 and the second mounting plate 4133, through the assembly part 533, such as the shaft assembly 535. The force between the support part 50 and the user's head cannot be adjusted. In order to improve the wearing comfort of the user, the assembly part 533 is adjusted so that the force between the support part 50 and the user's head can be adjusted.

In the assembly part 533, the assembly part body 534 is provided with mounting grooves 5342 on the surfaces facing the first mounting plate 4132 and the second mounting plate 4133, respectively, to cooperate with the shaft assembly 535. The assembly part body 534 is provided with a through hole 5343 penetrating the assembly part body 534, so as to communicate with the two mounting grooves 5342 provided on both sides of the assembly part body 534, and then cooperate with the shaft assembly 535.

[0147] In one embodiment, the assembly body 534 is provided with a travel portion 5344 on the inner wall of the mounting groove 5342 to cooperate with the rotating shaft assembly 535. In one embodiment, the travel portion 5344 may be a travel groove. The travel portion 5344, for example, is provided with two abutting surfaces, for example, a first abutting surface 5344a and a second abutting surface 5344b, in the travel groove to cooperate with the rotating shaft assembly 535. In some embodiments, in order to better cooperate with the rotating shaft assembly 535, the travel portion 5344, for example, is provided with a third abutting surface 5344c in the travel groove to cooperate with the rotating shaft assembly 535. The third abutting surface 5344c is located between the first abutting surface 5344a and the second abutting surface 5344b.

[0148] In one embodiment, the travel portion 5344 may be three protrusions disposed in the mounting groove 5342. For example, one of the three protrusions is provided with a first abutting surface 5344a, another is provided with a second abutting surface 5344b, and the last is provided with a third abutting surface 5344c to cooperate with the rotating shaft assembly 535. Of course, the three protrusions may be an integral structure. In one embodiment, the mounting groove 5342 may be omitted. The travel portion 5344 may be provided on the surfaces of the assembly portion body 534 facing the first mounting plate 4132 and the second mounting plate 4133, respectively. For example, the travel portion 5344 may be three protrusions.

[0149] It is understandable that the travel portion 5344 is not limited to the listed matching relationship of the travel groove and the three protrusions, and can also be other matching relationships. For example, the travel portion 5344 is arranged inside the assembly portion body 534. In addition, the third abutting surface 5344c can be omitted.

[0150] In one embodiment, the shaft assembly 535 may include a shaft 536 disposed in the through hole 5343 and connected and fixed to the first mounting plate 4132 and the second mounting plate 4133, and an elastic member 537 connected to the shaft 536 and engaged with the assembly body 534. The shaft 536 may be provided with a fixing portion 5361 to be fixedly connected or engaged with one end of the elastic member 537, for example, the first end 5371.

[0151] In one embodiment, the fixing portion 5361 may be a through hole or a groove penetrating the rotating shaft 536, so that one end of the elastic member 537, such as the first end 5371, extends into the through hole or the groove and engages with the rotating shaft 536. In one embodiment, the fixing portion 5361, such as the through hole, may be a strip-shaped through hole. The extending direction of the strip-shaped through hole may be consistent with the axial direction of the rotating shaft 536, so that one end of the elastic member 537, such as the first end 5371, extends into the through hole and engages with the rotating shaft 536 in the radial direction of the rotating shaft 536. In some embodiments, the extending direction of the strip-shaped through hole may also be inconsistent with the axial direction of the rotating shaft 536, so that under the cooperation of the assembly portion body 534, one end of the elastic member 537, such as the first end 5371, extends into the through hole and engages with the rotating shaft 536 in the radial direction of the rotating shaft 536.

[0152] See also Fig.15 and Fig.16 , Fig.15 This is an exploded view of the rotating shaft 536 and the connecting arm body 4131 from one perspective in one embodiment of the present application. Fig.16 For this application Fig.15 The exploded view of the rotating shaft 536 and the connecting arm body 4131 from another perspective in the illustrated embodiment. The rotating shaft 536 may include a rotating shaft screw 5362 having a fixing portion 5361 such as a through hole arranged in the axial direction and a rotating shaft screw 5363 screwed to the end of the rotating shaft screw 5362.

[0153] The rotating shaft screw 5362 may include a screw rod 5364 having one end screwed with the rotating shaft screw 5363 and arranged with a fixing portion 5361, such as a through hole, in the axial direction, and a screw head 5365 disposed at the other end of the screw rod 5364. The fixing portion 5361, such as the through hole, is extended toward one end of the screw rod 5364 screwed with the screw screw 5363 to extend to the edge of the screw rod 5364 so that the elastic member 537 slides from the edge of the rotating shaft screw 5362 into the fixing portion 5361, such as the through hole. The screw head 5365 is disposed opposite to the rotating shaft screw 5363 to be mounted on the connecting arm body 4131, such as the first mounting plate 4132 and the second mounting plate 4133, to prevent the elastic member 537 from sliding out of the fixing portion 5361, such as the through hole.

[0154] In some embodiments, in order to realize the connection and fixation between the rotating shaft 536 and the connecting arm body 4131, for example, the first mounting plate 4132 and the second mounting plate 4133. The first mounting plate 4132 is provided with a through hole 4132a, and a first fixing portion 4132b is provided around the through hole 4132a to fix with the rotating shaft 536 to prevent the rotating shaft 536 and the connecting arm body 4131 from rotating relative to each other. In one embodiment, the first fixing portion 4132b can be a groove. The second mounting plate 4132 is provided with a through hole 4133a to be arranged opposite to the through hole 4132a on the first mounting plate 4132, so that the rotating shaft 536, for example, the rotating shaft screw 5362, passes through the through hole 4132a and the through hole 4133a in sequence. The screw head 5365 is provided with a second fixing portion 5365a on the side facing the rotating shaft screw 5363 to fix with the first fixing portion 4132b. In one embodiment, the second fixing portion 5365a may be a bump to be placed in the first fixing portion 4132b, for example, in a groove, to achieve the fixing of the first fixing portion 4132b and the second fixing portion 5365a. Of course, the first fixing portion 4132b and the second fixing portion 5365a are not limited to the configuration relationship of the bump and the groove.

[0155] See also Fig.13 , Fig.14 , Fig.15 and Fig.16 , the elastic member 537 may be a torsion spring. In one embodiment, the elastic member 537 may also be other types of elastic members 537 such as elastic ropes, springs, reeds, etc. In one embodiment, the elastic member 537 may be a planar spiral spring, which surrounds the periphery of the rotating shaft 536. In one embodiment, there may be two elastic members 537, which correspond to the two mounting grooves 5342 one by one, and one elastic member 537 is installed in one mounting groove 5342. Of course, in some embodiments, the number of elastic members 537 may be one, and of course it may also be 3, 4, etc., and the number of elastic members 537 may not be limited.

[0156] One end of the elastic member 537, such as the first end 5371, is connected to or clamped with the fixing portion 5361 of the rotating shaft 536. In some embodiments, one end of the elastic member 537, such as the first end 5371, can slide from the edge of the screw rod 5364 into the fixing portion 5361, such as the through hole.

[0157] The other end of the elastic member 537, such as the second end 5372, slides in the travel portion 5344, such as the travel groove, and can slide to a state where the other end of the elastic member 537, such as the second end 5372, abuts against the abutting surface of the travel portion 5344, such as the first abutting surface 5344a and the second abutting surface 5344b, so that the other end of the elastic member 537, such as the second end 5372, is limited. Of course, in some embodiments, when the other end of the elastic member 537, such as the second end 5372, slides from the first abutting surface 5344a to the second abutting surface 5344b in the travel portion 5344, such as the travel groove, it can slide through the third abutting surface 5344c. When the other end of the elastic member 537, such as the second end 5372, abuts against the third abutting surface 5344c, the elastic member 537 can be elastically deformed, so that the elastic member 537 can slide relative to the third abutting surface 5344c.

[0158] It can be understood that in some embodiments, the second end 5372 of the elastic member 537 may abut against the two abutting surfaces of the travel portion 5344, such as the first abutting surface 5344a and the second abutting surface 5344b, respectively, when the two abutting surfaces of the travel portion 5344, such as the first abutting surface 5344a and the second abutting surface 5344b, are close to each other, and cannot slide on the travel portion 5334.

[0159] When realizing the rotation shaft assembly 535 and the assembly part body 534, the first mounting plate 4132, and the second mounting plate installation 4133, the elastic member 537 can be placed in the installation groove 5342, so that the second end 5372 of the elastic member 537 is placed in the travel part 5344, such as the travel groove, and the assembly part 534 is placed between the first mounting plate 4132 and the second mounting plate installation 4133, so that the through hole 5343, the through hole 4132a and the through hole 4133 are connected, and the rotation shaft screw 5362 is passed through the through hole 4132a, the through hole 5343 and the through hole 4133 in sequence, so that the elastic member 537 slides into the fixing part 5361, such as the through hole, the first clamping part 4132b is clamped with the second clamping part 5365a, the rotation shaft screw 5363 is screwed with the rotation shaft screw 5362, and then the rotation shaft 536 is installed in the first mounting plate 4132 and the second mounting plate 4133.

[0160] When the leg body 53 rotates around the rotating shaft 536, for example, when it rotates in the first direction, the elastic member 537 rotates relative to the leg body 53 along with the rotating shaft 636, so that the second end 5372 of the elastic member 537 slides in the travel portion 5344, such as the travel groove, and can slide to a state of abutting with the abutment surface, such as the second abutment surface 5344a. The leg body 53 continues to rotate around the rotating shaft 536, for example, in the first direction, which can cause the elastic member 537 to undergo elastic deformation. The elastic deformation generates a force that restores the elastic member 537 to its original state, thereby applying a force to the leg body 53 to rotate the leg body 53 in the second direction, thereby adjusting the force of the leg body 53 on the user's head, making the user more comfortable to wear. It can be understood that during the rotation of the leg body 53 around the rotating shaft 536, it can slide through the third abutment surface 5344c, so that the elastic member 537 abuts against the third abutment surface 5344c and undergoes elastic deformation, thereby increasing the difficulty of rotating the leg body 53 and allowing the user to experience the folding and unfolding of the leg body 53.

[0161] In one embodiment, when the other end of the elastic member 537, for example, the second end 5372, abuts against the first abutting surface 5344a in the travel portion 5344, for example, the travel groove, and slides to abut against the second abutting surface 5344b in the travel portion 5344, for example, the travel groove, the leg body 53 can be rotated 0-90° around the rotation axis 536. Of course, the design style of the travel portion 5344 is different, and the rotation angle of the leg body 53 around the rotation axis 536 can be adjusted.

[0162] In one embodiment, when the other end of the elastic member 537, for example, the second end 5372, abuts against the first abutting surface 5344a in the travel portion 5344, for example, the travel groove, and slides to abut against the third abutting surface 5344c in the travel portion 5344, for example, the travel groove, the leg body 53 can be rotated 0-70° around the rotation axis 536. Of course, the design style of the travel portion 5344 is different, and the rotation angle of the leg body 53 around the rotation axis 536 can be adjusted, for example, 45°.

[0163] It can be understood that the elastic member 537 can be only disposed on one side of the assembly body 534 facing the first mounting plate 4132 or the second mounting plate 4133. In some embodiments, the elastic member 537 can also be disposed inside the assembly body 534, and the travel portion 5344 is also disposed inside the assembly body 534.

[0164] In addition, the rotating shaft 536 can also be fixed on the assembly body 534 , and structures such as the mounting groove 5342 and the travel portion 5344 can be set on at least one of the first mounting plate 4132 and the second mounting plate 4133 .

[0165] It is understood that in some embodiments, Fig.13 and Fig.14 The matching relationship between the second evacuation portion 5341 of the leg body 53 and the connecting arm body 4131, such as the abutment plate 4134, is as follows: Fig.10 and Fig.11 The matching relationship between the second evacuation portion 5341 of the leg body 53 and the connecting arm body 4131, such as the abutment plate 4134, is different. Fig.13 and Fig.14 The cooperation between the second yielding portion 5341 of the leg body 53 and the connecting arm body 4131, such as the abutment plate 4134, enables the leg body 53 to rotate at a larger angle relative to the connecting arm body 4131, that is, the unfolding angle is larger when unfolded. Fig.10 and Fig.11 The cooperation between the second yielding portion 5341 of the leg body 53 and the connecting arm body 4131, such as the abutment plate 4134, makes the rotation angle of the leg body 53 relative to the connecting arm body 4131 smaller, that is, the unfolding angle when unfolded is smaller. The unfolding angle difference between the two can be 0-12°. That is, Fig.13 and Fig.14 The middle leg body 53 has a larger folding angle relative to the connecting arm body 4131.

[0166] in, Fig.13 and Fig.14 As shown, a rotating shaft assembly 535 is provided between the supporting leg body 53 and the connecting arm body 4131, so that when the unfolding angle is large, the rotating shaft assembly 535 can be used to adjust the force of the supporting leg body 53 on the user's head.

[0167] For example, when the leg body 53 rotates around the rotation axis 536, for example, in the first direction, the elastic member 537 rotates relative to the leg body 53 along with the rotation axis 636, so that the second end 5372 of the elastic member 537 slides in the stroke portion 5344, for example, in the stroke groove, and can slide to a state of abutting against the abutting surface, for example, the second abutting surface 5344a. The leg body 53 continues to rotate around the rotation axis 536, for example, in the first direction, so that the elastic member 537 is elastically deformed. A force is generated to restore the elastic member 537 to its original state, and then a force is applied to the leg body 53 to rotate the leg body 53 in the second direction, i.e., a rebound force, thereby adjusting the force of the leg body 53 on the user's head, making the user more comfortable to wear. When the leg body 53 continues to rotate around the rotating shaft 536, for example, rotates in the first direction, it can be rotated until the abutment plate 4134 of the connecting arm body 4131 is located at the second yielding portion 5341 of the leg body 53 to limit the leg body 53.

[0168] See also Figure 3, the first functional lens module 20 may include a first functional lens 21 and a second functional lens 22 mounted on the first housing 41. The first functional lens 21 and the second functional lens 22 are symmetrically arranged.

In some embodiments, functional lenses such as the first functional lens 21 and the second functional lens 22 may include only one lens. In one embodiment, the function of the first functional lens 21 and the function of the second functional lens 22 may be different. Of course, in some embodiments, the function of the first functional lens 21 and the function of the second functional lens 22 may be the same.

[0170] The lens can be made of one or more transparent or translucent materials such as glass, plastic, etc. The lens can also be made of one or more transparent materials, translucent materials, opaque materials, etc. for a certain light transmission effect.

[0171] In one embodiment, the lens may be a vision correction lens made of one or more lenses such as convex lenses and concave lenses. Of course, other types of lenses or functional lenses (such as flat lenses, anti-glare lenses, colored lenses, etc.) or functional films (such as anti-reflection films, polarization films, filter films, electrochromic films, photochromic films, etc.) may also be provided in the vision correction lens. In one embodiment, the lens may be a myopia lens.

[0172] In other embodiments, the lens may also be a lens with other functions such as a flat lens, an anti-glare lens, a colored lens, etc.

[0173] In one embodiment, the lens may also be a photochromic device (e.g., a photochromic film). For example, the photochromic device may be made of a photochromic material, so that the photochromic device can change color after being excited by light of a certain wavelength. The photochromic material may be made using existing technical solutions in the prior art within the scope of understanding of those skilled in the art, and will not be described in detail.

[0174] In one embodiment, the lens may also be an electrochromic device (e.g., an electrochromic film). For example, the electrochromic device may be made of an electrochromic material. The electrochromic material may be one of an inorganic electrochromic material and an organic electrochromic material. The inorganic electrochromic material may be tungsten trioxide. The organic electrochromic material may be one of polythiophenes and their derivatives, viologens, tetrathiafulvalene, metal phthalocyanine compounds, etc. Of course, the electrochromic material may be made using existing technical solutions in the prior art within the scope of understanding of those skilled in the art, and no further description is given.

[0175] The electrochromic device can be electrically connected to the electronic circuit system inside the head-mounted device 100 to achieve control of the electrochromic device.

[0176] In one embodiment, the lens may be an optical waveguide, specifically a planar grating waveguide such as a diffraction grating waveguide. The head mounted device 100 may present a virtual reality / augmented reality environment through the lens.

[0177] It can be understood that the lens can also be a structure formed by combining the lenses in any of the above embodiments, which will not be described in detail.

[0178] In one embodiment, the number of lenses may be two, for example, a first lens 23 and a second lens 24. The first lens 23 and the second lens 24 are stacked. In one embodiment, the first lens 23 and the second lens 24 may be of different types. For example, the first lens 23 is an optical waveguide, and the second lens 24 is a flat lens. In one embodiment, one of the first lens 23 and the second lens 24 may be omitted. In some embodiments, the first functional lens module 20 may be omitted.

[0179] The first lens 23 may be disposed between the mounting frame body 4121 and the assembly frame body 4411. The first lens 23 is fixed by clamping the mounting frame body 4121 and the assembly frame body 4411. In one embodiment, the first lens 23 may cover a side of the shielding member 42 away from the body 4111. In one embodiment, the first lens 23 may abut against a side of the shielding member 42 away from the first convex edge 4112, and abut against a surface of the second sub-convex edge 4113b away from the body 4111.

[0180] Taking the first lens 23 as an optical waveguide as an example, the first lens 23 may be provided with an optical coupling light inlet portion at a position opposite to the light through hole 4222, and may be provided with an optical coupling light outlet portion at a position opposite to the light transmission hole 4122. The optical coupling light inlet portion and the optical coupling light outlet portion are connected together to form an optical path, and light is coupled into the lens from the optical coupling light inlet portion, transmitted in the optical path, and finally the light is coupled out of the lens at the optical coupling light outlet portion, and is emitted into the wearer's eyes and formed on the retina.

[0181] In one embodiment, the first lens 23 may include a lens body 231 provided with a light coupling light inlet portion and a light coupling light outlet portion, and an electrochromic film 232 provided on a side of the lens body 231 facing the mounting frame body 4121 or the assembly frame body 4411. The provision of the electrochromic film 232 solves the problem of the single color of the first lens 23.

[0182] In one embodiment, the lens body 231 may be provided with an electrochromic film 232 on both the side facing the mounting frame body 4121 and the side facing the assembly frame body 4411 .

[0183] In one embodiment, the electrochromic film 232 may be omitted. In one embodiment, the lens body 231 may be a flat lens or a myopia lens, etc., without a light coupling-in portion and a light coupling-out portion.

[0184] See also Figure 3 Fig.17 , Fig.17 For this application Figure 3 Schematic diagram of the structure of the first functional lens 21 in the illustrated embodiment. The lens body 231 is provided with an extension portion 2311, and the extension portion 2311 can extend to a position overlapping with the fixed cover.

[0185] It can be understood that the lens body 231 in the first lens 23 may have different functions from the lens body 231 in the second lens 24. For example, the lens body 231 in the first lens 23 may be an optical waveguide, and the lens body 231 in the second lens 24 may be a flat lens or a myopia lens.

[0186] Take the second lens 24 as a myopia lens as an example. The second lens 24 can be located on the side of the first lens 23 facing the mounting frame body 4121. A second connector 241 is provided on the side of the second lens 24 facing the channel shell 411 so as to be connected and fixed with the first connector 43, such as the second sub-connector 432. The second connector 241 can be a metal that can generate a magnetic force or a composite material containing a metal with a magnetic force, so as to be connected to the second sub-connector 432 by magnetic force. Of course, the matching relationship between the second connector 241 and the second sub-connector 432 is not limited to the magnetic force connection, and it can also be a matching relationship such as a plug-in connection, a snap connection, an adhesive connection, a screw connection, etc.

[0187] It is understandable that the number of lenses in the first functional lens 21 may be different from the number of lenses in the second functional lens 22. For example, the first functional lens 21 is provided with a first lens 23 and a second lens 24, and the second functional lens 22 is provided with a first lens 23.

The first circuit system 30 can be used to realize at least one of the functions of the first functional lens module 20, such as augmented reality, virtual reality, and color change. Of course, in some embodiments, the first circuit system 30 can also be used to realize the function of the external device 400.

[0189] The first circuit system 30 may include a mainboard module 31, an optical-mechanical assembly 32, a battery module 33, and a speaker module 34 electrically connected together through a flexible circuit board 35. The battery module 33 may provide power for the normal operation of the mainboard module 31, the optical-mechanical assembly 32, and the speaker module 34. The mainboard module 31 may be used to control the normal operation of the optical-mechanical assembly 32 and the speaker module 34.

In one embodiment, the first mainboard 311 may also be disposed in the clamping space 41d of the first connecting arm 413a. In one embodiment, the first mainboard 311 may also be disposed in the clamping space 41d of the second connecting arm 413b. In one embodiment, the first mainboard 311 may also be disposed in the accommodation space 530 of the second leg 52.

[0191] In one embodiment, the second main board 312 may also be disposed in the clamping space 41d of the first connecting arm 413a.

In one embodiment, the second main board 312 may also be disposed in the accommodation space 530 of the second leg 52.

[0192] In one embodiment, the functional devices integrated on the first main board 311 and the functional devices integrated on the second main board 312 may be integrated on one main board, that is, one of the first main board 311 and the second main board 312 may be omitted.

[0193] The optical-mechanical assembly 32 can be used as a display assembly, and the optical-mechanical assembly 32 can be arranged in the clamping space 41d of the first connecting arm 413a. The optical-mechanical assembly 32 is electrically connected to the mainboard module 31, such as the first mainboard 311, through the first flexible circuit board 351. The first flexible circuit board 351 can be extended from the accommodating space 530 of the first leg 51 to one side of the first connecting arm 413a, and extend to between the abutting side wall 542 and the main body 534 of the assembly part, and extend from between the abutting side wall 542 and the main body 534 of the assembly part into the clamping space 41d of the first connecting arm 413a to be electrically connected to the optical-mechanical assembly 32. The optical-mechanical assembly 32 can include at least an optical machine. The optical machine can emit light with image information (also referred to as an "optical signal"). The light can pass through the connecting hole 41c and the light-through hole 4222 from the optical coupling-in optical part of the first lens 23 to couple into the first lens 23, so that the light is coupled out from the optical coupling-out optical part of the first lens 23. Of course, in some embodiments, the optical-mechanical assembly 32 may be disposed in the clamping space 41d of the second connecting arm 413b. It is understandable that there may be two optical-mechanical assemblies 32, one of which is disposed in the clamping space 41d of the first connecting arm 413a, and the other may be disposed in the clamping space 41d of the second connecting arm 413b.

[0194] The optical-mechanical assembly 32 can be electrically connected to the mainboard module 31, such as the second mainboard 312, through the second flexible circuit board 352. The second flexible circuit board 352 can be arranged in the wiring channel 41a, that is, the second flexible circuit board 352 is arranged in the channel shell 411. It is sandwiched between the body 4111 and the shielding member 42 to be shielded by the shielding member 42 to prevent the second flexible circuit board 352 from being exposed.

[0195] In one embodiment, an electrical connection end, such as a second electrical connection end 3521, is disposed at one end of the second flexible circuit board 352 corresponding to the position of the first mounting hole 4223 of the first fixing cover 422 to be electrically connected to the first electrical connection end 2321 of the first lens 23 of the first functional lens 21.

[0196] In one embodiment, when the second main board 312 is omitted, another optical-mechanical assembly 32 can be installed in the location where the second main board 312 is installed, that is, in the clamping space 41d of the second connecting arm 413b. The other optical-mechanical assembly 32 can be installed and arranged according to the installation method of the optical-mechanical assembly 32 in the first connecting arm 413a, so that the other optical-mechanical assembly 32 can cooperate with the first lens 23 in the second functional lens 22.

[0197] The battery module 33 may be disposed in the accommodation space 530 of the second leg 52. It may be electrically connected to the second flexible circuit board 352 and / or the second main board 312 through the third flexible circuit board 353. The third flexible circuit board 353 may be extended from the accommodation space 530 of the second leg 52 to one side of the first connecting arm 413a, and extend to between the abutting side wall 542 and the assembly part body 534, and extend from between the abutting side wall 542 and the assembly part body 534 into the clamping space 41d of the second connecting arm 413b to be electrically connected to the second flexible circuit board 352 and / or the second main board 312.

[0198] It is understandable that the battery module 33 may also be disposed in the accommodating space 530 of the first leg 51. In some embodiments, the battery module 33 may also be disposed in the fastening space 41d of the first connecting arm 413a, or in the fastening space 41d of the second connecting arm 413b.

[0199] The speaker module 34 may include a first speaker 341 disposed in the accommodation space 530 of the first leg 51 and a second speaker 342 disposed in the accommodation space 530 of the second leg 52. The first speaker 341 is disposed in the accommodation space 530 of the first leg 51 corresponding to the second mounting hole 53a of the leg body 53 so that the sound is transmitted to the outside through the second mounting hole 53a. The second speaker 342 is disposed in the accommodation space 530 of the second leg 52 corresponding to the second mounting hole 53a of the leg body 53 so that the sound is transmitted to the outside through the second mounting hole 53a. In one embodiment, at least one of the first speaker 341 and the second speaker 342 may be omitted.

[0200] In one embodiment, the first circuit system 30 may further include a first external connector electrically connected to the mainboard module 31 and / or the battery module 33. The first external connector may be arranged corresponding to the first mounting assembly 55, such as the mounting seat 551, for example, extending from the second mounting hole 53a of the leg body 53 into the third mounting hole 5512 and the fourth mounting hole 5531, so that when the first mounting assembly 55 is connected to an external device, such as an external power supply or an external device 400, data transmission between the external device and the external device is realized, or power is provided to the external device, or the external device provides power to the first circuit system 30. In one embodiment, the first external connector may be a pogo pin or a contact matched with a pogo pin. In one embodiment, the first external connector may be a part of the first mounting assembly 55. In one embodiment, the first external connector may be arranged inside the mounting seat 551, for example, the first external connector is directly fixed in the third mounting hole 5512.

[0201] In one embodiment, the first circuit system 30 may not be limited to the mainboard module 31, the optical machine component 32, the battery module 33, and the speaker module 34 listed in the above embodiment, and it may also include electronic components, such as microphones, such as Hall sensors. The Hall sensor can be used to sense the changes in the magnetic field around the first mounting component 55, so that the mainboard module 31 controls the normal operation of the first circuit system 30 according to the results sensed by the Hall sensor. For example, the installation and removal of the external device 400 can be sensed by the change in the magnetic field, and the task management of the head-mounted device 100 can be further realized, and the switching of the sleep mode, working mode, etc. of the head-mounted device 100 system can be realized to optimize power consumption. In one embodiment, the Hall sensor can be installed on the first mounting component 55, and of course it can also be installed in other locations, which will not be described here.

[0202] It can be understood that in the first circuit system 30, the portion of the first circuit system 30 located in the first leg 51 can be called the "first part", the portion of the first circuit system 30 located in the second leg 52 can be called the "second part", the portion of the first circuit system 30 located in the first connecting arm 413a can be called the "third part", and the portion of the first circuit system 30 located in the second connecting arm 413b can be called the "third part", and the first part and the third part are electrically connected through the first flexible circuit board 351, the third part and the fourth part are electrically connected through the second flexible circuit board 352, and the second part and the fourth part are electrically connected through the third flexible circuit board 353.

[0203] In some embodiments, the names of "first part", "second part", "third part", "fourth part" and "part" can be interchanged. For example, in one embodiment, the "first part" in other embodiments is called "second part", and correspondingly, the "second part" in other embodiments is called "first part".

[0204] In some embodiments, since the assembly process of the wearable device 200 is relatively complicated, and the arrangement of the flexible circuit boards 35, such as the first flexible circuit board 351 and the third flexible circuit board 353, needs to pass through the assembly portion 533 set on the leg body 53, which makes the design of the assembly portion body 534 too complicated. In addition, the first flexible circuit board 351 and the third flexible circuit board 353 will be bent back and forth during use, causing the first flexible circuit board 351 and the third flexible circuit board 353 to have bending damage, thereby reducing the life of the flexible circuit boards 35, such as the first flexible circuit board 351 and the third flexible circuit board 353, so the flexible circuit boards 35, such as the first flexible circuit board 351 and the third flexible circuit board 353, need to be redesigned.

[0205] In some embodiments, the names of "first flexible circuit board", "second flexible circuit board", "third flexible circuit board" and "flexible circuit board" can be interchanged. For example, in one embodiment, the "first flexible circuit board" in other embodiments is called the "second flexible circuit board", and correspondingly, the "second flexible circuit board" in other embodiments is called the "first flexible circuit board".

When the connecting arm body 4131 rotates around the rotating shaft assembly 535, the abutment plate 4134 can be located at the second yielding portion 5341, that is, when the first leg 51 is in the unfolded state, the first electrical interface 3513 and the second electrical interface 3514 are abutted to achieve electrical connection. When the connecting arm body 4131 rotates around the rotating shaft assembly 535, the abutment plate 4134 can be away from the second yielding portion 5341, that is, when the first leg 51 is in the folded state, the first electrical interface 3513 and the second electrical interface 3514 are not abutted, and thus the circuit cannot be conducted. It can be understood that the first electrical interface 3513 can also be set at other positions of the second yielding portion 5341, as long as the first electrical interface 3513 can be electrically connected to the second electrical interface 3514 when the abutting plate 4134 is located at the second yielding portion 5341. In addition, the first electrical interface 3513 and the second electrical interface 3514 are not limited to being set at the end surfaces of the abutting plate 4134 and the connecting arm body 4131 at the second yielding portion 5341. The first electrical interface 3513 can also be set at other positions on the assembly portion 533, and the second electrical interface 3514 can also be set at other positions of the first connecting arm 413a.

[0208] In one embodiment, one of the first electrical interface 3513 and the second electrical interface 3514 is a pogo pin, and the other is a contact that matches the pogo pin.

[0209] By setting the electrical connection component, the first electrical interface 3513 and the second electrical interface 3514 can be electrically connected or disconnected when the connecting arm body 4131 rotates around the rotating shaft component 535. In addition, the normal operation of the head mounted device 100 can be controlled. The electrical connection component functions as a switch. In addition, the first flexible circuit board 351 is protected. It can be understood that the third flexible circuit board 353 can have a similar structure to the first flexible circuit board 351. For example, the third flexible circuit board 353 can also include a first sub-flexible circuit board 3511, a second sub-flexible circuit board 3512, a first electrical interface 3513, and a second electrical interface 3514. For the use of the third flexible circuit board 53 in the first circuit system 30, refer to the first flexible circuit board, and no further description is given.

Among them, the general structure of the second mounting assembly 86 is the same as the general structure of the first mounting assembly 86, except that the second mounting assembly 86 does not have a mounting base for carrying the second magnet member 861, the second decorative sheet 862 and the second external connector 863. For the arrangement and matching relationship between the second magnet member 861 and the fixing groove 8441 and the second decorative sheet 862, reference can be made to the arrangement and matching relationship between the first magnet member 552, the mounting base 551, the accommodating groove 5511 and the first decorative sheet 553 in the above-mentioned embodiment, and no further elaboration is given.

[0236] In some embodiments, the third housing 84 serves as a mounting base for carrying the second magnet 861, the second decorative sheet 862, and the second external connector 863, wherein the fixing groove 8441 can be omitted, the second magnet 861 can be directly fixed to the bottom surface of the assembly groove 844, the second decorative sheet 862 is arranged on the side of the second magnet 861 facing the first mounting assembly 55, and the second decorative sheet 8411 abuts against the side wall of the assembly groove 844 to divide the assembly groove 844 into two parts. In some embodiments, the part of the assembly groove 844 used to install the second magnet 861 can also be called a "fixing groove".

[0237] In addition, the second external connector 863 can be used to electrically connect to an external device such as an external power supply, a wearable device 200 such as a first external connector, to achieve data transmission between the external device, or to provide power to the external device, or the external device provides power to the second circuit system 90, or the first circuit system 30 provides power to the second circuit system 90. In one embodiment, the second external connector 863 may be a pogo pin or a contact paired with a pogo pin. It can be understood that the electrical connection relationship between the first external connector and the second external connector 863 may not be limited to the matching relationship between the pogo pin or the contact paired with the pogo pin, and other matching relationships may also be other interfaces such as USB interfaces, etc., which will not be elaborated. It can be understood that a Hall sensor electrically connected to the first external connector is provided on the first mounting component 55 for detecting the magnetic field strength of the second electromagnetic component 861, and a Hall sensor electrically connected to the second circuit system 90 is provided on the second mounting component 863 for detecting the magnetic field strength of the first electromagnetic component 552. When the first external connector and the second external connector 863 are electrically connected, both Hall sensors can be electrically connected to the second circuit system 90, and then the external device 400 can be controlled according to the system preset control method.

[0238] It is understandable that the names of "first magnet member", "second magnet member" and "magnet member" can be interchanged in some embodiments. For example, in one embodiment, the "first magnet member" in other embodiments is called the "second magnet member", and correspondingly, the "second magnet member" in other embodiments is called the "first magnet member".

[0239] In some embodiments, the names of "first decorative sheet", "second decorative sheet" and "decorative sheet" can be interchanged. For example, in one embodiment, the "first decorative sheet" in other embodiments is called "second decorative sheet", and correspondingly, the "second decorative sheet" in other embodiments is called "first decorative sheet".

[0240] See also Fig.11 , Fig.12 , Fig.25 and Fig. 27 , Fig. 27 This is a schematic diagram of the structure of the first mounting component 55 and the second mounting component 86 in one embodiment of the present application. When the wearable device 200 mounts the external device 400, the first mounting component 55 can be extended into the assembly groove 844, so that the first decorative sheet 553 and the second decorative sheet 862 are arranged opposite to each other. In one embodiment, the first decorative sheet 553 and the second decorative sheet 862 can be arranged at intervals or abutted. The first magnet member 552 and the second magnet member 861 are attracted by the magnetic force between each other, so that the first mounting component 55 and the second mounting component 86 are connected.

[0241] It can be understood that since the first mounting component 55 needs to extend into the assembly slot 844 to complete the mounting of the external device 400 on the wearable device 200, the structure and shape of the assembly slot 844 and the structure and shape of the first mounting component 55, such as the mounting seat 551, can achieve the positioning function. For example, the cross section of the assembly slot 844 perpendicular to the direction of depression toward the shell body 841 can be one of elliptical, rectangular, polygonal, etc., and of course can also be a special shape. Correspondingly, the mounting seat 551 can be perpendicular to the direction extending from the leg body 53 to the side away from the leg side cover 54. The cross section can be adapted to the cross section of the assembly slot 844 perpendicular to the direction of depression toward the shell body 841, so that the mounting seat 551 can extend into the assembly slot 844 to strengthen the connection strength between the first mounting component 55 and the second mounting component 86.

[0242] In addition, the first mounting assembly 55 can form an external assembly with the second mounting assembly 86. Of course, the external assembly may not be limited to the first mounting assembly 55 and the second mounting assembly 86. The external assembly may also include other, such as the third housing 84 can be replaced with an assembly seat, and the assembly seat is used as a part of the external assembly, wherein structures such as the assembly groove 844, the fixing groove 8441 and the hole 8442 that cooperate with the second mounting assembly 86 on the third housing 84 may be arranged on the assembly seat. When using the external assembly, the assembly seat may be fixed on an object, and the mounting seat 551 may be fixed on another object, so as to realize the detachable connection of two objects. For example, the assembly seat may be fixed on the third housing 84, and the mounting seat 551 may be fixed on the first leg 51, so as to realize the detachable connection of the third housing 84 and the first leg 51.

[0243] In one embodiment, the mounting base may be a part of the first mounting assembly 55 .

[0244] See also Fig. 27 , two first magnet members 552 may be provided in the first mounting assembly 55, wherein the two first magnet members 552 have different magnetic poles (also referred to as "opposite magnetic poles"). Fig. 27The magnetic pole of the first magnet component 552 on the left side of the first mounting component 55 facing the second mounting component 86 is the south pole (i.e., the S pole), and the magnetic pole of the first magnet component 552 on the right side facing the second mounting component 86 is the north pole (i.e., the N pole). The second mounting component 86 can be provided with two second magnet components 861 corresponding to the two first magnet components 552 in the first mounting component 55, wherein the two second magnet components 861 have different magnetic poles. Fig. 27 The magnetic pole of the second magnet component 861 on the left side of the second mounting component 86 facing the first mounting component 55 is the N pole, while the magnetic pole of the second magnet component 861 on the right side facing the first mounting component 55 is the S pole.

[0245] When the first mounting assembly 55 is connected to the second mounting assembly 86 by magnetic force, Fig. 27 In the embodiment, the first magnet 552 on the left side of the first mounting assembly 55 and the second magnet 861 on the left side of the second mounting assembly 86 have different magnetic poles, thereby generating a magnetic force. The first magnet 552 on the right side of the first mounting assembly 55 and the second magnet 861 on the right side of the second mounting assembly 86 have different magnetic poles, thereby generating a magnetic force to attract each other.

[0246] See also Fig.28 , Fig.28 This is a schematic diagram of the structure of the first mounting assembly 55 and the second mounting assembly 86 in another embodiment of the present application. Fig.28 In the embodiment, after the first mounting assembly 55 is vertically mirrored (i.e., reversed left and right), the first magnet component 552 on the left side of the first mounting assembly 55 and the second magnet component 861 on the left side of the second mounting assembly 86 have the same magnetic poles, and thus generate a magnetic force of repulsion. The first magnet component 552 on the right side of the first mounting assembly 55 and the second magnet component 861 on the right side of the second mounting assembly 86 have the same magnetic poles, and thus generate a magnetic force of repulsion. As a result, the first mounting assembly 55 and the second mounting assembly 86 cannot be connected by magnetic force.

[0247] It can be seen that in Fig. 27 In the embodiment, the first mounting assembly 55 has a plurality of first magnets 552 centrally distributed and when two first magnets 552 are centrally symmetrical about a symmetric point, the magnetic poles are different. The second mounting assembly 86 has a plurality of second magnets 861 centrally distributed and when two second magnets 861 are centrally symmetrical about a symmetric point, the magnetic poles are different. Fig. 27 Install as shown, they can be installed together correctly. Fig. 27 The first mounting assembly 55 in the embodiment is reversed left and right. Fig.28As shown, the first mounting component 55 and the second mounting component 86 will repel each other due to the change in the magnetic pole arrangement, thereby preventing the wearable device 200 and the external device 400 from being installed together when the first mounting component 55 is turned upside down. The user can sense the position misalignment according to the change in the magnetic force of opposite poles attracting each other or like poles repelling each other, and can adjust the relative position of the first mounting component 55 and the second mounting component 86 accordingly, until the change in the magnetic force is used to guide the user to put the external device 400 into a reasonable position set by the wearable device 200. When the wearable device 200 and the external device 400 are blindly disassembled and installed, the first mounting component 55 and the second mounting component 86 can be disassembled and conveniently assembled by sensing the magnetic force between the first magnet component 552 and the second magnet component 861. In addition, the relative position between the first mounting component 55 and the second mounting component 86 can be adjusted according to the magnetic force guidance between the first magnet component 552 and the second magnet component 861.

[0266] See also Fig.31 and Fig.32 , Fig.32 For this application Fig.31A schematic diagram of the structure of the driving device 832 in the illustrated embodiment. The driving device 832 is disposed between the support seat 831 and the third shell 84, and can be used to adjust the distance between the support seat 831 and the third shell 84, and further adjust the distance between the support seat 831 and the shell side cover 82, so that the touch key 834 can be extended from the connecting hole 8211 to the outside of the storage space 840, or retracted from the outside of the storage space 840 to the inside of the storage space 840.

Among them, one end of the telescopic screw 8323 is connected to the support seat 831, so as to adjust the distance between the support seat 831 and the third shell 84 under the push of the telescopic screw 8323. The telescopic screw 8323 is rotatably connected to the driving member 8322 so as to adjust the distance between the support seat 831 and the base 8321 of the telescopic screw 8323 under the drive of the driving member 8322.

In this case, controlling the touch portion 8342 does not allow the user to better confirm the position of the touch portion 8342. Under the control of the driving device 832, the touch key 834 can be extended out of the storage space 840, so that the touch key 834, such as the touch portion 8342, protrudes from the surface of the side cover body 821. In this case, controlling the touch portion 8342 can allow the user to better confirm the position of the touch portion 8342.

Among them, the Hall sensor can be used to sense the change of the magnetic field around the second mounting component 86, so that the mainboard module 91 controls the normal operation of the second circuit system 30 according to the result of the Hall sensor sensing. For example, the installation and removal of the external device 400 can be sensed by the change of the magnetic field, and the task management of the head-mounted device 100 can be further realized, and the switching of the sleep mode, working mode, etc. of the head-mounted device 100 system can be realized, and the power consumption can be optimized. In one embodiment, the Hall sensor can be installed on the second mounting component 86, and of course it can also be installed in other positions such as the assembly slot 844, which will not be described in detail here.

The second heat sink 962 is used to dissipate heat from the battery module 93. The first heat sink 961 abuts against the second heat sink 962. In one embodiment, the first heat sink 961 and the second heat sink 962 may be one of a copper foil, a copper sheet, a nano-carbon heat sink, an aluminum foil heat sink, and the like.

[0277] In some embodiments, the second circuit system 90 may not be limited to the mainboard module 91, the optical-mechanical component 92, the battery module 93, the speaker 94, the antenna component 95 and the capacitive flexible circuit board 833, but may also include a microphone, various types of sensors, etc., which will not be repeated here.

[0278] It can be understood that the first circuit system 30 can be electrically connected to the second circuit system 90 to form an electronic circuit system.

As for the arrangement of the electronic circuit system in the wearable device 200 and the external device 400, please refer to the description in the above embodiment, which will not be repeated here.

[0279] In addition, the touch key assembly 83, such as the capacitive flexible circuit board 833, can be used as a common part of the housing assembly 80 and the second circuit system 90, so in some embodiments, the touch key assembly 83 can be a part of the second circuit system 90, rather than a part of the housing assembly 80. When the first circuit system 30 can be electrically connected with the second circuit system 90 to form an electronic circuit system, the electronic circuit system can be both provided in the wearable device 200, and accordingly, the touch key assembly 83 can also be provided in the accommodation space 530 of the leg (for example, one of the first leg 51 and the second leg 52) in the wearable device 200. The matching relationship between the touch key assembly 83 and the leg side cover 54 can be set according to the matching relationship between the touch key assembly 83 and the main housing 81. The matching relationship between the touch key assembly 83 and the housing side cover 82 can be set according to the matching relationship between the touch key assembly 83 and the leg body 53.

[0280] Next, a control method is described. The method can be used for the head mounted device 100 in the above embodiment to control the head mounted device 100. Fig.34 , Fig.34 This is a flow chart of a control method in an embodiment of the present application, the method comprising:

[0281] Step S3201: Detect the first magnetic field strength at the position of the second mounting component.

[0282] In the above embodiment, the second mounting component 86 is provided on the external device 400, and the second mounting component 86 can be connected to the first mounting component 55 through the magnetic force between the first magnet component 552 and the second magnet component 861. Then, when the first magnet component 552 and the second magnet component 861 are close to each other, the first magnetic field strength around the second magnet component 861 can be disturbed by the first magnet component 552 and change, so that the change of the first magnetic field strength can indirectly represent the distance between the first magnet component 552 and the second magnet component 861. Therefore, the first magnetic field strength can be used as a measure of whether the external device 400 is mounted on the wearable device 200. In one embodiment, it can be measured by a Hall sensor provided in the second mounting component 86. It can be understood that in the scenario where the second magnet component 861 is provided on the second mounting component 86, the second magnetic field strength around the first magnet component 552 can also be used as a measure of whether the external device 400 is mounted on the wearable device 200.

[0283] Step S3202: if it is detected that the first magnetic field strength is greater than the first preset threshold, granting the touch key component the authority to control the first circuit system.

[0284] Here, the first preset threshold is determined according to the magnetic field strength of the first magnet 552, the magnetic field strength of the second magnet 861, and the distance between the first magnet 552 and the second magnet 861. The magnetic field strength when the first magnet 552 and the second magnet 861 realize the external device 400 being mounted on the wearable device 200 is taken as the maximum magnetic field strength, and the first preset threshold may be slightly less than the maximum magnetic field strength. Of course, the first preset threshold may also be adjusted. It is understandable that when the first magnetic field strength is greater than the first preset threshold, the first magnet 552 and the second magnet 861 may be brought closer to each other due to the magnetic field force, so that the first magnetic field strength increases from the first preset threshold to the maximum magnetic field strength, and the external device 400 is mounted on the wearable device 200. It is understandable that when the second magnetic field strength is used as a measure of whether the external device 400 is mounted on the wearable device 200, the second preset threshold is involved, and the difference between the magnetic field strength of the first magnet 552 and the magnetic field strength of the second magnet 861 may determine whether the first preset threshold is the same as the second preset threshold. When the magnetic field strength of the first magnet 552 is the same as the magnetic field strength of the second magnet 861 , the first preset threshold is the same as the second preset threshold.

[0285] When the external device 400 is mounted on the wearable device 200, the external device 400 can be controlled by the touch key component 83. It can be understood that when the external device 400 is not mounted on the wearable device 200, in order to protect the external device 400 and to better experience the external device 400, the function of the touch key component 83 to control the external device 400 can be canceled.

[0286] Step S3203: A message indicating that the external device has been successfully mounted on the framework structure is displayed.

[0287] When the first magnetic field strength is greater than the first preset threshold, the first magnet 552 and the second magnet 861 can be brought closer to each other due to the magnetic field force, so that the first magnetic field strength increases from the first preset threshold to the maximum magnetic field strength, and the external device 400 is mounted on the wearable device 200. Therefore, when the external device 400 is mounted on the wearable device 200, the first circuit system 30, such as a speaker, can be used to prompt that the external device 400 is successfully mounted on the frame structure, or the third functional lens 62 can be used in conjunction with the optical machine to display the information that the external device 400 is successfully mounted on the frame structure, or the indicator light can be used to prompt that the external device 400 is successfully mounted on the frame structure. Of course, other methods can also be used to prompt, which will not be repeated.

[0288] See also Fig.35 , Fig.35 This is a flow chart of a control method in another embodiment of the present application. After step S3203, the method further includes:

[0289] Step S3304: If a touch operation on the touch key component is detected, the external device is controlled through the first circuit system.

[0290] When the external device 400 is mounted on the wearable device 200, the first circuit system 30 will give the touch key component 83 the ability to control the external device 400, and then through the touch operations of the touch key component such as double-click, single-click, long press, short press, etc., the external device 400 can be turned on, off, selected, canceled, deleted, played, forward, backward, page turning and other functions, thereby completing the control of the external device 400.

[0291] Step S3305: If it is detected that the first magnetic field strength is less than the first preset threshold, the permission of the touch key component to control the first circuit system is cancelled, and the external device is controlled to enter a low power standby state.

[0292] When the first magnetic field strength is less than the first preset threshold, it means that the external device 400 is not mounted on the wearable device 200. Therefore, at this time, the external device 400 is not used. Therefore, the external device 400 can enter a low-power standby state, that is, a sleep state, which can ensure the standby time of the external device 400 and improve the user experience.

[0293] Step S3306: If it is detected that the first magnetic field strength is less than the first preset threshold, the external device 400 is controlled to shut down.

[0294] Referring to step S3305, controlling the external device 400 to shut down can ensure the standby time of the external device 400 and improve the user experience.

[0295] Step S3307: If it is detected that the first magnetic field strength is less than the first preset threshold, a message indicating that the external device 400 is not successfully mounted on the frame structure is displayed.

[0296] Referring to steps S3304 and S3305, when the external device 400 is not mounted on the wearable device 200, the user can be reminded in time to improve the user experience. In addition, problems such as misoperation can be avoided.

[0297] It can be understood that steps S3304, S3305, S3306, and S3307 can be performed in any order.

[0298] Please refer to Fig.36 , Fig.36 This is a flow chart of a control method in another embodiment of the present application. The method may include:

[0299] Step S3401: Detect the first magnetic field strength at the position of the second mounting component.

[0300] Please refer to step S3201 and no further details will be given.

[0301] Step S3201: Detect the second magnetic field strength at the position of the second mounting component.

[0302] Please refer to step S3201 and no further details will be given.

[0303] Step S3201: If the first magnetic field strength is detected to be greater than the first preset threshold and the second magnetic field strength is detected to be greater than the second preset threshold, the touch key component is granted authority to control the first circuit system, and the first mounting component is provided with a second magnet component that generates a magnetic field to change the second magnetic field strength when the first mounting component is close to the second mounting component.

[0304] Please refer to steps S3201 and S3202, which will not be described in detail. It can be understood that the combined use of the first magnetic field strength and the second magnetic field strength can improve the probability of determining whether the external device 400 is mounted on the wearable device 200 and avoid misoperation.

[0305] Step S3203: A message indicating that the external device has been successfully mounted on the framework structure is displayed.
