The snap structure 1116 and the snap structure 1223 may constitute a first connection mechanism provided between the top plate 111 and the mounting plate 122, and the snap structure 1124 and the snap structure 1214 may constitute a second connection mechanism provided between the bottom plate 121 and the first side plate, the first connection mechanism and the second connection mechanism cooperating the main front case 11 and the main rear case 12 to form the accommodation chamber 17 for accommodating the main body of the head-mounted device 100. In other embodiments, the first connection mechanism may be a threaded connection or an adhesive structure, and the second connection mechanism may be a threaded connection or an adhesive structure.

It should be noted that when the first housing assembly 10 is described separately (i.e., when not described in conjunction with the second housing assembly 30), the main front housing 11 may also be referred to as a first housing, and the main rear housing 12 may also be referred to as a second housing.

Mask 13 of first housing assembly 10

Referring to fig. 10 and 11, the mask 13 may be translucent and may include a mask portion 131, a mounting portion 132, and a lens assembly 133. The mask portion 131 includes a first mask portion 1311, a second mask portion 1312, and a connecting portion 1313 positioned intermediate the first mask portion 1311 and the second mask portion 1312.

The first and second cover parts 1311 and 1312 have optical characteristics of light transmittance, and light transmittance is satisfied at least at two through holes 1132 corresponding to the second portion 113 of the main front case 11 to achieve the following properties: external light can pass through the first mask portion 1311 and the second mask portion 1312 without the human eye being able to see objects inside the mask 13 from the outside. For example, the translucent effect is achieved by processing the mask 13 to reduce its transmittance so that the human eye cannot see the structure inside the mask 13, but the image pickup assembly 70 can receive external light from the inside of the mask 13, thereby enabling imaging of an object or the like outside. The material of the mask 13 may include plastic or hardware, etc.

The connecting portion 1313 has a through hole 1314 formed therein corresponding to the through hole 1131 of the second portion 113. The mounting portion 132 extends rearward from the edge of the mask portion 131, i.e., toward the main front shell 11. The edge of the mounting portion 132 remote from the mask portion 131 may be provided with one or more snap features 1321, such as hooks or bosses. The inner surfaces of the two sides of the mounting portion 132 may be provided with one or more guide structures 1322, such as horizontally extending bosses or steps. These snap features 1321 and guide features 1322 are respectively configured to be cooperatively connected with the snap features 1141 and guide features 1142 of the connecting portion 114 of the front main housing 11, so as to mount the mask 13 to the front main housing 11, for example, to attach the first mounting portion 132 to the connecting portion 114 of the first side plate. The coverage area of the mask 13 is larger than the coverage area of the main front shell 11 when viewed from the right front of the mask 13. Thus, when the face mask 13 is mounted on the main front shell 11, only the upper portion of the face mask 13 is in conforming connection with and covers the first side plate of the main front shell 11 (e.g., the upper portion of the face mask portion 131 covers the second portion 113 of the first side plate), while the lower portion of the face mask 13 is lower than the main front shell 11, i.e., extends downwardly beyond the main front shell 11 (see fig. 4), and correspondingly beyond the bottom plate 121. The rear cover 14 and the lower portion of the face mask 13 serve to form a protective space therebetween to protect the waveguide piece 63 therebetween. The upper portion of the mask 13 may be the upper half of the mask 13 and the lower portion of the mask 13 may be the lower half of the mask 13.

The fastening structure 1321 of the mask 13 and the fastening structure 1141 of the connecting portion 114 may form a connection structure between an edge of the first mounting portion 132 away from the mask portion 131 and the connecting portion 114, and the fastening structure 1321 is in fastening connection with the fastening structure 1141. The guide structure 1322 of the mask 13 and the guide structure 1142 of the connecting portion 114 may constitute a guide structure between a surface of the first mounting portion 132 facing the connecting portion 114 and the connecting portion 114, the guide structure 1322 being in sliding engagement with the guide structure 1142.

The lens assembly 133 can be inserted into the through-hole 1314. The lens assembly 133 may include a lens holder 1331, and a first lens 1332 and a second lens 1333 mounted on the lens holder 1331. The lens holder 1331 may include a first through hole 1334, a second through hole 1335, and a third through hole 1336. The first through hole 1334 may be centrally disposed, and the second and third through holes 1335 and 1336 are located at both sides of the first through hole 1334. The first lens 1332 may be inserted and fixed in the first through hole 1334 from the rear. The second lens 1333 may include two lens portions 1338 corresponding to the second and third through holes 1335 and 1336, respectively, and a through hole 1339 located between the two lens portions. The second lens 1333 may be coupled to the front surface of the lens holder 1331 by an adhesive 134. The lens holder 1331 may also be provided on a front surface thereof with an annular flange 1337 surrounding the first, second and third through holes 1334, 1335 and 1336. The protruding length of the annular flange 1337 may be equal to the thickness of the second lens 1333, such that the second lens 1333 may be received within the space enclosed by the annular flange 1337. The lens holder 1331 may be coupled to the rear surface of the connection portion 1313 by an adhesive member 135, and the annular flange 1337 may be inserted into the through hole 1314. The adhesive 134 and the adhesive 135 may be double-sided tape, or the like.

In the assembled lens assembly 133, the first lens 1332 is inserted into the first through hole 1334 and is opposite to the through hole 1339; the two lens portions 1338 are opposite to the second through hole 1335 and the third through hole 1336, respectively.

Rear cover 14 of first housing assembly 10

Referring to fig. 12, the rear cover 14 may be transparent, and may include a light-transmitting portion 141 and a mounting portion 142. The light-transmitting portion 141 has a light-transmitting property by the optical characteristic arrangement, so that the light emitted from the opto-mechanical assembly 60 can be incident on the eyes of the user through the light-transmitting portion 141. The light-transmitting portion 141 may be disposed substantially parallel to the mask portion 131 of the mask 13. The mounting portion 142 extends rearward from the other edge of the light-transmitting portion 141 except the upper edge, i.e., in a direction away from the mask 13, and a flange 1421 is formed outwardly of the edge of the mounting portion 142 away from the light-transmitting portion 141. Referring to fig. 5, the rear cover 14 can be assembled with the lower portion of the mask 13 and correspondingly positioned below the bottom plate 121; wherein the rear cover 14 may be brought closer toward the mask 13 such that the light transmitting portion 141 and the mounting portion 142 are inserted into the lower portion of the mask 13 until the flange 1421 abuts against the end face of the mounting portion 132 of the mask 13 (see also fig. 20). The rear cover 14 may also be coated with an adhesive to strengthen the connection at the portion that contacts the face mask 13 and the main rear shell 12. Since the waveguide sheet 63 (see fig. 14) of the opto-mechanical assembly 60 generally comprises a glass material, which is fragile, the protection of the waveguide sheet 63 from both the outside and the inside by the face mask 13 and the rear cover 14 provides a high safety against damaging the eyes of the user by accidental crushing of the glass material. In addition, the rear cover 14 may be fully transparent, with a higher light transmittance than a normal transparent material, so that the user can clearly see the picture displayed by the waveguide 63 when wearing the head-mounted device 100.

Main housing trim 15 of first housing assembly 10

Referring to fig. 13, the main housing decoration 15 may be crescent-shaped as a whole, and the top surface 151 may be streamline-shaped or smooth, etc. to increase the aesthetic appearance of the product. The main housing decoration 15 may be disposed on the top plate 111 to cover the top plate 111, that is, the top of the main front housing 11, so that the main housing decoration 15 may be also referred to as a cover plate; further, the arcs of the two opposite sides of the cover plate 15 are also the same as the arcs of the inner side 1111 of the top plate 111 and the outer side 1112 of the top plate 111, respectively. Referring to fig. 5, one or more key holes 152 may be formed on both sides of the main housing decoration 15, and the number of key holes 152 is the same as the number of side keys 16; for example, two key holes 152 are provided in the left front position of the main housing trim 15, and two key holes 152 are provided in the right front position of the main housing trim 15. These key holes 152 are provided vertically corresponding to the housing portions 1113 on the top plate 111 of the main front case 11. The four side keys 16 are respectively disposed above the accommodating portion 1113 of the top plate 111, and partially protrude from the main housing decoration 15 through the key holes 152 of the main housing decoration 15, so that a user can press the side keys 16 to adjust various parameters of the head-mounted device 100. Since the four side keys 16 are located approximately at the left and right front positions of the first housing assembly 10, the operation and use by the user are facilitated. The inner side 153 of the main housing trim 15 further defines a recess 154 centrally therein. The lower surface 155 of the main housing trim 15 is provided with one or more downwardly projecting lugs 156, which lugs 156 may have threaded bores. As described above, the main housing trim 15 is for placement in the space defined by the top plate 111 and the ridge 1125 of the main front housing 11; wherein the boss 156 of the main housing trim 15 may pass through the through hole 1114 of the top plate 111 to be fixed to the top plate 111 of the main front housing 11.

Referring back to fig. 4 and 5, when the first housing assembly 10 is assembled, the main front housing 11 and the main rear housing 12 are assembled by the engagement of the snap structures 1124, 1116, 1214, 1223 thereon. The mask 13 can be engaged with the fastening structure 1141 by the fastening structure 1321 to cover the front of the main front housing 11. The rear cover 14 may be adjacent to the mask 13 and inserted into the lower portion of the mask 13. The main housing trim 15 is then mounted over the top of the main front housing 11.

Referring to fig. 14, a perspective view of the opto-mechanical assembly 60 of the headset 100 is shown in an embodiment of the present application. The opto-mechanical assembly 60 may include an opto-mechanical holder 61, an opto-mechanical 62 and a waveguide plate 63.

The light machine bracket 61 may include a top plate 611, a side plate 612 extending from one side of the top plate 611, and two legs 613 extending from the top plate 611 and located at both sides of the top plate 611 and the side plate 612.

The top plate 611 may be horizontally disposed. It should be noted that the top plate 611 is not necessarily provided in a continuous and flat plate shape, and may be provided with a recess at one or more positions to reduce the weight of the structure while satisfying the supporting strength. The top plate 611 may be provided with one or more through holes 6111 for mounting with other components. These through holes 6111 may or may not be threaded. The top plate 611 may also be provided at a front position thereof with one or more elongated through holes 6112 for the passage of the FPC. The side plate 612 extends downward from the front edge of the top plate 611, and the two legs 613 are respectively located at the left and right sides of the top plate 611 and extend downward. The middle position of the side plate 612 is provided with a through hole 6121 and a through hole 6122, and two sides of the middle position of the side plate 612 are respectively provided with a through hole, namely a through hole 6125 and a through hole 6126, and the through holes 6121, 6122, 6125 and 6126 can be used for inserting the camera component 70. The through-holes 6121 and 6122 are disposed adjacent, and the distance from the through-hole 6121 to the through-hole 6126 may be equal to the distance from the through-hole 6122 to the through-hole 6125. The through-holes 6121 and 6122 correspond to the central through-hole 1131 formed in the second portion 113 of the main front case 11 as a whole, and the through-holes 6125 and 6126 correspond to the two through-holes 1132 formed in the second portion 113 of the main front case 11, respectively, and these through-holes 1131 and 1132 are used for passing through external light to be received by the image pickup assembly. The lower end of each leg 613 may be provided with a through hole 6131.

The number of the optical machines 62 is two, and the number of the waveguide plates 63 is also two. The two light engines 62 and the two waveguide plates 63 may be arranged on a connector 64, i.e. the light engines 62 and the waveguide plates 63 are held by the connector 64. The connector 64 may have one or more through holes 641. These through holes 641 may be threaded or unthreaded. The two light engines 62 may be symmetrically arranged within the receiving chamber 17.

A spacer 65 may also be provided under the connector 64. The gasket 65 may be sleeved on the waveguide plate 63 and abuts against the lower surface of the connecting body 64. The gasket 65 is interposed between the connection body 64 and the bottom plate 121 of the main rear case 12 during assembly, and prevents the connection body 64 from being rigidly contacted with the main rear case 12, thereby protecting the same. The cushion 65 may be made of a compressible or resilient material such as flexible rubber, foam, or the like.

Each light engine 62 may also be connected to a heat sink 621 within the receiving chamber 17 for thermally conductive connection and dissipation of one or more heat sources 622, such as LED lamps, of the light engine 62. In one embodiment, the heat sink 621 can include a first heat sink portion 6211, a second heat sink portion 6212, and a third heat sink portion 6213.

For example, the third heat dissipation portion 6213 may extend perpendicularly from the junction of the first heat dissipation portion 6211 and the second heat dissipation portion 6212. Wherein, the second heat dissipation portion 6212 may be connected to a heat source 622 for dissipating heat; the third heat dissipating portion 6213 may be connected to another heat source 622 for dissipating heat. The first heat dissipation portion 6211, the second heat dissipation portion 6212 and the third heat dissipation portion 6213 of the heat dissipation sheet 621 may be provided separately from each other or may be provided as an integral structure to facilitate assembly; in addition, the heat sink 621 may also extend into the interior space of the opto-mechanical assembly 60 and/or the first housing assembly 10, and may also simultaneously dissipate heat from more heat-generating components by contacting other heat-generating components. For example, the first heat dissipating portion 6211 of the heat sink 621 may extend rearward to be thermally conductively connected to the power FPC 213 (see fig. 28) or the second heat sink 225 (see fig. 33) of the tie assembly 20. At least one of the heat sink 621 and the second heat sink 225 may comprise a graphite sheet.

Each light engine 62 may be a projector. The light engine 62 provides light to the waveguide plate 63, which light comprises information and/or images for providing enhanced user observation of the world of matter. Light from the light engine 62 may be coupled into the waveguide sheet 63, the light being totally internally reflected within the waveguide sheet 63, and the light being then coupled out of the waveguide sheet 63 so that the light may be seen by a user.

When assembled, screws can be used to pass through the through holes 6111 of the top plate 611 and the through holes 641 of the connecting body 64, so as to fix the optical machine bracket 61, the optical machine 62 and the waveguide sheet 63 together. In the assembled opto-mechanical assembly 60, an accommodating space is defined between the connector 64 and the side plate 612 of the opto-mechanical holder 61, for accommodating a part of the imaging assembly 70.

Referring to fig. 15, another perspective view of the opto-mechanical holder 61 of the opto-mechanical assembly 60 of fig. 14 is shown. As shown in fig. 15, on the rear side surface of the side plate 612, and on both sides of the middle position thereof where the through holes 6121 and 6122 are defined, a clamping groove 6123 and an abutment portion 6124 are respectively provided, and the position of the clamping groove 6123 may be higher than the position of the abutment portion 6124. The abutment 6124 may have a flat surface and may be provided with a threaded hole. On the rear side of the side plate 612, a clamping groove 6127 is provided on one side thereof at a position where the through hole 6125 is defined, and a clamping groove 6128 and an abutment portion 6129 are provided on the other side thereof. The clip groove 6128 and the abutment 6129 may be directly adjacent. The top end of the slot 6127 is flush with the top end of the slot 6128, but the length of the slot 6127 extending downward is greater than the length of the slot 6128 extending downward. The abutment 6129 may have a flat surface and may be provided with a threaded bore. The position of the clamping groove 6128 may be higher than the position of the abutment 6129. On the rear side surface of the side plate 612, a clamping groove and an abutting portion which are the same as or similar to the clamping groove 6127, the clamping groove 6128 and the abutting portion 6129 are provided at a position where the through hole 6126 is defined, and a description thereof will be omitted.

Image pickup assembly 70

Referring to fig. 16, a camera assembly 70 of a headset 100 in an embodiment of the application is shown. The camera assembly 70 is mounted on the camera support 61 of the optical-mechanical assembly 60 and may include a TOF (Time of flight, or TOF) camera 71, an RGB camera 72, two fisheye cameras 73, a first camera support 74 for fixing the TOF camera 71 and the RGB camera 72, and two second camera supports 75 for fixing the two fisheye cameras 73 respectively.

The TOF camera 71 may include a light emitting module 711, a light receiving module 712, an FPC 713, and a heat sink 714. The light emitting module 711 and the light receiving module 712 are connected to the FPC 713. The light emitting module 711 has a front end portion, which may also be the front end portion of the TOF camera 71. The heat sink 714 is connected to the FPC 713, for example, is attached to the rear surface of the FPC 713, and dissipates heat. The heat sink 714 has a rear side that may also be the rear side of the TOF camera 71. When the TOF camera 71 works, the light emitting module 711 is configured to emit a modulated light beam, where the light beam is reflected by the target object and received by the light receiving module 712, and the light receiving module 712 can obtain the time of flight of the light beam in space by demodulation, so as to calculate the distance of the corresponding target object. Thus, by means of the TOF camera 71, the shape and model of a room can be modeled as the user wears the headset 100 around an environment such as a room; that is, the shape and model of the room in which the user is located can be determined by measuring the distance from each point to the head mounted device 100 worn by the user, thereby constructing a scene.

The RGB camera 72 may be used to capture two-dimensional color images, color differences of captured images, etc., and is coupled to the TOF camera 71 and may be secured by a first camera mount 74. The RGB camera 72 may include a camera body 721 and an FPC 722. The camera body 721 has a front end portion, which may also be the front end portion of the RGB camera 72. The camera body 721 is connected to the FPC 722. The FPCs 722 and 713 may be connected together at an upper end. The heat sink 714 may also be attached to the FPC 722, for example, by bonding to the rear surface of the FPC 722, to dissipate heat. The rear side of the heat sink 714 may also be used as the rear side of the RGB camera 72.

The front ends of the TOF camera 71 and the RGB camera 72 may also be sleeved with a gasket 76. The gasket 76 is used to be sandwiched between the TOF camera 71 and the RGB camera 72 and the side plate 612 of the camera holder 61 during assembly, so as to prevent the TOF camera 71 and the RGB camera 72 from being in hard contact with the camera holder 61, thereby protecting the same. The gasket 76 may be made of a compressible or resilient material such as flexible rubber, foam, or the like.

Each fisheye camera 73 may include a camera body 731, a camera mounting plate 732, and an FPC 733. The camera body 731 has a tip portion, and the tip portion may be a tip portion of the fisheye camera 73. The camera body 731 is connected to the FPC 733 and mounted on the camera mounting plate 732. The FPC 733 has a rear side surface, and the camera mount plate 732 also has a rear side surface; the FPC 733 or the camera mounting plate 732 may be disposed close to the second camera mount 75, in which case its corresponding rear side may be the rear side of the fisheye camera 73. The camera mounting plate 732 may include a body portion 7321, a first mating portion 7322, and a second mating portion 7323. The body portion 7321 is for carrying the camera body 731. For example, the camera body 731 may be fixed to the body portion 7321 by a dispensing process or screws. The first and second insertion portions 7322 and 7323 are located on both sides of the main body portion 7321, respectively. In the up-down direction, the first and second insertion portions 7322 and 7323 may be located at a position above the middle of the main body portion 7321, that is, a connection position of the first and second insertion portions 7322 and 7323 with the main body portion 7321 is near the top of the main body portion 7321. The side of the first socket 7322 may include a semi-cylindrical portion and the side of the second socket 7323 may also include a semi-cylindrical portion.

In one embodiment, the TOF camera 71 and the RGB camera 72 are disposed adjacent to each other and receive external light through the first through hole 1131, and the two fisheye cameras 73 are located on both sides of the TOF camera 71 and the RGB camera 72. The two fisheye cameras 73 are mainly used for matched imaging. Of course, the arrangement of the positions of the cameras is not limited thereto, and can be adjusted according to actual needs. In addition, the types of cameras are not limited to this, and different types of cameras can be selected according to actual needs.

Different cameras and different arrangement positions are adopted, so that the imaging principle and the imaging effect are different. For example, the four cameras of the TOF camera 71, the RGB camera 72, and the two fisheye cameras 73 may complement each other; the fisheye camera 73 may be a wide-angle camera, but may have a relatively low resolution. The resolution of the RGB camera 72 may be relatively high, but the photographing angle thereof may be relatively small, and by combining the RGB camera 72 with the fish-eye camera 73, a relatively clear image with a relatively large photographing angle may be formed.

The first camera mount 74 is located behind the TOF camera 71 and RGB camera 72 to mount the two TOF cameras 71 and RGB cameras 72 on the camera mount 61 of the opto-mechanical assembly 60. The first camera mount 74 may include an intermediate portion 741, a plug portion 742, and a fixing portion 743. The middle portion 741 has a pressing surface toward the TOF camera 71 and the RGB camera 72, which may include two flat surfaces, i.e., a first flat surface 7411 and a second flat surface 7412. The insertion portion 742 and the fixing portion 743 are located on both sides of the middle portion 741, respectively; in the up-down direction, the insertion portion 742 and the fixing portion 743 may be located at different height positions on both sides of the middle portion 741, for example, the insertion portion 742 may be located higher than the fixing portion 743. The sides of the plug 742 may include semi-cylindrical portions to facilitate rotation within the catch 6123. The fixing portion 743 has a through hole 744.

The two second camera brackets 75 are symmetrically arranged and are respectively positioned behind the two fisheye cameras 73. Each second camera mount 75 may include an intermediate portion 751, a mating portion 752, and a securing portion 753. The intermediate portion 751 is connected between the insertion portion 752 and the fixing portion 753, and is provided away from the fisheye camera 73 from the insertion portion 752 and the fixing portion 753. The insertion portion 752 and the fixing portion 753 are located on both sides of the intermediate portion 751, respectively. In the up-down direction, the insertion portion 752 and the fixing portion 753 may be located at the same or different height positions on both sides of the intermediate portion 751; for example, the insertion portion 752 may be located at a middle or a middle lower position on the side of the middle portion 751, that is, a connection position of the insertion portion 752 and the middle portion 751 is located between the top and the bottom of the middle portion 751 or near the bottom of the middle portion 751; the fixing portion 753 may be located at an intermediate position on the other side of the intermediate portion 751. The sides of the socket 752 may include semi-cylindrical portions to facilitate rotation within the slot 6127. The fixing portion 753 has a through hole 754.

Referring to fig. 15, 16 and 17 together, when the TOF camera 71 and the RGB camera 72 are assembled to the optical unit 60, the TOF camera 71 and the RGB camera 72 are fixed to the optical unit 61 of the optical unit 60 by the first camera mount 74. Specifically, the TOF camera 71 and the RGB camera 72 may be inserted into the through hole 6121 and the through hole 6122 of the optical bench 61 from the rear, the insertion portion 742 may be inserted into the clamping groove 6123 of the optical bench 61, the fixing portion 743 may be pressed against the abutment portion 6124, the screw may be inserted through the through hole 744 of the fixing portion 743, and the TOF camera 71 and the RGB camera 72 may be screwed into the threaded hole of the abutment portion 6124 of the optical bench 61, so that the middle portion 741 may be pressed against the rear sides of the TOF camera 71 and the RGB camera 72. In an assembled state of the image pickup assembly 70 and the optical machine assembly 60 in the first housing assembly 10, the front end portion of the light receiving module 712 of the TOF camera 71 is inserted into the through hole 6121 of the optical machine bracket 61.

Since the third microphone 925 and the fourth microphone 927 may be located lower than the PCB 81, a support 929 may be provided between the PCB 81 and the third microphone 925 and the fourth microphone 927. That is, the third microphone 925 and the fourth microphone 927 may be supported by a support 929, and the support 929 may be fixed on the PCB 81. The third microphone 925 may be connected to the PCB 81 through an FPC 926, and the fourth microphone 927 may be connected to the PCB 81 through an FPC 928. In one embodiment, the FPCs 926 and 928 may be joined to the PCB 81 after being joined to the FPC 713 of the camera assembly 70. In other embodiments, the FPCs 926 and 928 may be connected to the PCB 81, respectively, or the FPCs 926 and 928 may be joined and then connected to the PCB 81.

By arranging the microphone assemblies 92 such that they are less interfering with each other, the directivity is more different.
