Thus, the main body device 100 of the present embodiment may refer to a device for providing an optical component, a display device, a functional device (such as a camera, a speaker, or a microphone), and a control component (such as a circuit board) in a head-mounted apparatus. The body device 100 is engageable with a wearing part to thereby enable wearing of the body device 100 on a head of a human body.

It will be appreciated that the duct 11 formed between the first housing 1 and the main unit 2 may be formed by:

in the first alternative embodiment, when the main unit 2 is provided in the first casing 1, a gap is provided between the outer periphery of the main unit 2 and the inner wall surface of the first casing 1, and the gap can be formed as the air duct 11.

In a second alternative embodiment, a gap is provided between the main unit 2 itself, for example, a gap may be formed between components included in the main unit 2 itself, and the air duct 11 may be formed by communicating with the air outlet 10 through the gap.

In a third alternative embodiment, a gap may be provided between the inner wall surface of the first housing 1 and the outer periphery of the main unit 2, and the main unit 2 itself is also provided with a gap, so that these gaps together form the air duct 11.

In some embodiments, the first casing 1 is provided with air outlets 10 at both ends in the length direction thereof, and the air outlets 10 may include a first air outlet 10a at one end of the first casing 1 and a second air outlet 10b at the other end of the first casing 1. The first air outlet 10a and the second air outlet 10b are respectively disposed at two ends of the first housing 1 in the length direction, and the air duct 11 can disperse heat to the first air outlet 10a and the second air outlet 10b to respectively discharge air, so that heat dissipation can be accelerated, and the heat dissipation effect of the main body device 100 is improved.

Alternatively, the air outlet 10 may be an entire air outlet 10 or may be an air outlet 10 formed by a plurality of air outlet holes. For example, a plurality of strip-shaped air outlet holes may be provided in the first casing 1, and the plurality of strip-shaped air outlet holes form the air outlet 10.

In some embodiments, in order to quickly transfer heat to the air outlet 10 and improve the heat dissipation effect, the first housing 1 may further be provided with an air inlet 12, the air inlet 12 may be located between two ends of the first housing 1, and the air duct 11 may be in communication with the air inlet 12 and located between the air inlet 12 and the air outlet 10. Specifically, the air inlet 12 may be disposed in a middle position of the first housing 1, so that the air outlet 10 and the air inlet 12 are spaced farther apart, and thus the area through which the air duct 11 passes may be longer, and the heat source area through which the air duct passes is larger, which is beneficial to taking more heat away from the air outlet 10. In addition, the air inlet 12 is disposed at the middle position of the first casing 1, when the first air outlet 10a and the second air outlet 10b are disposed at two ends of the first casing 1, the air (or air) entering from the air inlet 12 can be divided into two paths, and the air is discharged to the first air outlet 10a and the second air outlet 10b along the channel with heat, so that the condition that the heat dissipation effect is affected due to the fact that the hot air discharged from the first air outlet 10a and the second air outlet 10b enters again through the air inlet 12 can be avoided. It will be appreciated that in other embodiments, the air inlet 12 may be disposed at a non-central position of the first housing 1, for example, the air inlet 12 may be disposed closer to the first air outlet 10a or the second air outlet 10b.

Alternatively, the air inlet 12 may be formed by providing a plurality of air inlet holes on the first housing 1 or the whole air inlet 12, and illustratively, a plurality of air inlet holes may be provided on the first housing 1, and the plurality of air inlet holes may be strip-shaped holes, circular holes or partially strip-shaped holes, and partially circular holes. The air inlet holes can be arranged at intervals and are arranged along the length direction of the first shell 1, so that the communication part with the channel can be increased, and the air inlet quantity is increased to improve the heat dissipation effect.

Referring to fig. 4 to fig. 6, in some embodiments, the main body device 100 further includes a lens 3, the first housing 1 includes a first frame portion 13 and a cover portion 14, the first frame portion 13 is used for mounting the lens 3, one end of the cover portion 14 is connected to the first frame portion 13, the cover portion 14 is used for enclosing with the first frame portion 13 to form an accommodating space 13a for accommodating the host 2, and the air inlet 12 and the air outlet 10 may be disposed on the cover portion 14. In particular, the covering portion 14 may be in the form of an elongated shell which may enclose the side of the first frame portion 13 facing away from the lens 3 for mounting, so as to avoid blocking the lens 3 mounted on the first frame portion 13.

Further, the first housing 1 further includes a lens frame portion 15, one end of the lens frame portion 15 is connected to an end of the cover portion 14 away from the first frame portion 13, the other end of the lens frame portion 15 is mounted corresponding to the first frame portion 13, and the lens frame portion 15 is configured to hold at least a portion of the host 2. In this way, the frame portion 15, the cover portion 14, and the first frame portion 13 collectively enclose the accommodating space 13a, and the host computer 2 can be accommodated in the accommodating space 13 a.

Specifically, the frame portion 15 and the cover portion 14 may be of unitary construction and constitute the rear case 1a of the first casing 1. In other words, the frame portion 15 and the cover portion 14 may be integrally formed so that the frame portion 15 and the cover portion 14 serve as the rear case 1a of the first case 1. Molding the frame portion 15 and the cover portion 14 as one piece can simplify assembly of the components of the body device 100. It will be appreciated that in other embodiments, the frame portion 15 and the cover portion 14 may be separate structures, and they may be assembled together by bonding, screwing, fastening, or welding to form the rear case 1a of the first case 1.

Referring to fig. 5 to 7, in some embodiments, the first housing 1 further includes an adapter portion 16, one end of the adapter portion 16 is connected to the first frame portion 13, and the other end of the adapter portion 16 is used to connect to a wearing portion that can wear the main body device 100 on the head of the user. Specifically, the adapter portion 16 is connected to one end of the first frame portion 13 in its own length direction, thereby facilitating connection of the adapter portion 16 with the wearing portion. Considering that the wearing part is to be worn on the head of the user, the number of the switching parts 16 may be two, and the two switching parts 16 are respectively connected to both ends of the first frame part 13.

Alternatively, the adapter portion 16 and the first frame portion 13 may be integrally formed and constitute the front case 1b of the first case 1. Providing the adapter portion 16 and the first frame portion 13 as a unitary structure may simplify assembly of the components of the body apparatus 100. It will be appreciated that in other embodiments, the adaptor portion 16 and the first frame portion 13 may be a separate structure, and they may be assembled together by bonding, screwing, buckling, welding, or the like to form the front case 1b of the first case 1.

In some embodiments, the junction between the adapter portion 16 and the first frame portion 13 encloses the vent opening 13b, and the air outlet of the air outlet 10 can be discharged through the vent opening 13 b. Specifically, the adapter 16 comprises a first portion 161 and a second portion 162 connected to each other, the first portion 161 being adapted to connect to the first frame part 13 and the second portion 162 being adapted to be rotatably connected to the wearing part. The connection between the first portion 161 and the first frame part 13 may enclose the ventilation opening 13b, and the second portion 162 and the wearing part may be rotatably connected to facilitate storage of the wearing part.

Alternatively, the adapting portion 16 may be a shell structure with a hollow portion, two ends of the hollow portion of the adapting portion 16 may be connected to the first frame portion 13, so that the ventilation opening 13b can be formed between the first frame portion 13 and the adapting portion 16, the ventilation opening 13b is an opening of the hollow portion, so that heat discharged from the air outlet 10 on the covering portion 14 can be further discharged through the ventilation opening 13b between the first frame portion 13 and the adapting portion 16, so that heat is prevented from being accumulated on the adapting portion 16, and a heat dissipation effect is improved.

In some embodiments, the first housing 1 further includes an extension end 17, one end of the extension end 17 may be connected to the covering portion 14, and the other end of the extension end 17 is used to be fixed with the second portion 162 of the adapting portion 16, so as to implement connection between the covering portion 14 and the adapting portion 16, and the first frame portion 13. Specifically, the two ends of the covering portion 14 in the length direction are respectively connected with an extension end 17, and the extension ends 17 can extend into the vent opening 13b where the first frame portion 13 and the adapting portion 16 are connected, so that the connection position of the covering portion 14 and the adapting portion 16 can be hidden, and the appearance decoration effect of the main body device 100 is improved.

Optionally, the extension end 17 extends into the vent hole 13b where the first frame part 13 and the adapting part 16 are connected and is connected with the adapting part 16 by a screw connection manner, so that the screw connected with the adapting part 16 can be hidden, and the appearance decoration effect of the main body device 100 is improved.

Further, as can be seen from the foregoing, the air outlets 10 are disposed at two ends of the covering portion 14, when the extending end 17 extends into the air vent 13b at the connection position of the first frame portion 13 and the adapting portion 16, the air outlets 10 can be disposed towards the adapting portion 16, so that the position of the air outlets 10 can be hidden by the adapting portion 16, on one hand, the user is not easy to see the user's vision, and is difficult to touch the air outlets 10, so that the user cannot feel the high-temperature hot air exhausted from the air outlets 10 at relevant positions (such as the head, the hand, etc.), and the isolation of the hot air of the air outlets 10 is realized. On the other hand, the hiding of the air outlet 10 can be realized, which is very beneficial to the integrity and the aesthetic property of the whole appearance model of the head-mounted equipment.

In some embodiments, at least a portion of the surface 163 of the adapter 16 is opposite the air outlet 10, and the at least a portion of the surface 163 may be used to direct the air out of the air outlet 10. Specifically, the at least part of the surface 163 may be a surface of the adapting portion 16 facing the first frame portion 13, which may be opposite to the air outlet 10, so that a hot air flow (such as heat or hot air) exiting from the air outlet 10 may form a swirling turbulent air mass through the surface of the adapting portion 16, thereby reducing the discharge speed of the hot air flow therein and avoiding the heat from being greatly accumulated at the hollow opening of the adapting portion 16.

Further, at least a portion of the surface 163 of the adapter 16 encloses a recess recessed toward a side away from the air outlet 10, and the recess is used for guiding the air outlet of the air outlet 10. Specifically, the recess may have at least a portion of the surface 163 described above. By adopting the mode that at least part of the surface of the switching part 16 is surrounded to form the concave part which is concave towards the direction far away from the air outlet 10, the hot air flow discharged through the air outlet 10 can form a whirling turbulent air mass, so that the discharge speed of the hot air flow can be greatly reduced.

In some embodiments, the first housing 1 further includes a protective cover 18, where the protective cover 18 is covered on the periphery of the first frame portion 13 and the adapting portion 16, and the protective cover 18 is further covered on at least a portion of the covering portion 14 connected to the first frame portion 13. Specifically, the protection cover 18 may serve as a decorative protection cover, which may perform a decorative function on the main body device 100, on the one hand, and on the other hand, the protection cover 18 may cover the connection position of the first frame portion 13 and the adapter portion 16, conceal the rotation shaft or the screw or the like to which the two are connected, and conceal the electrical connectors (such as a flexible circuit board, an electric wire or the like for connecting to the wearing portion) on the first frame portion 13 and the adapter portion 16.

Further, the protection cover 18 may be made of a heat conductive material, such as a metal material, so that the protection cover 18 may also assist in dissipating heat generated by the host 2 to the outside. For example, the protection cover 18 may be made of aluminum alloy, etc. to provide good appearance decoration effect and also effectively assist heat dissipation.

Referring again to fig. 3 to 6, in some embodiments, the cover portion 14 may include a cover portion 14a connected to the first frame portion 13 and side plate portions 14b connected to two ends of the cover portion 14a, the air outlet 10 may be disposed on the side plate portion 14b, and the air inlet 12 may be disposed on the cover portion 14a. Specifically, the side plate portions 14b at the two ends of the cover plate portion 14a may extend obliquely downward from the two end portions of the cover plate portion 14a, and the extending ends 17 may extend outward from the connection between the cover plate portion 14a and the side plate portion 14b, so that when the extending ends 17 extend into the connection between the adapter portion 16 and the first frame portion 13, the extending ends 17 may cover the side plate portion 14b, so that the air outlet 10 provided on the side plate portion 14b is formed as the hidden air outlet 10.

Further, the cover plate portion 14a may include a first cover plate portion 141 connected to the first frame portion 13 and a second cover plate portion 142 connected to the first cover plate portion 141, and the first cover plate portion 141 and the second cover plate portion 142 may be connected at an angle to form an approximately L-shaped cover plate portion 14a. The first cover plate portion 141 may be disposed substantially horizontally, the second cover plate portion 142 may be substantially perpendicular to the first cover plate portion 141, and the air duct 11 may include a first air duct 11a (as indicated by a dotted arrow in fig. 4, which also indicates the direction of air flow in the first air duct 11 a) between the main unit 2 and the first cover plate portion 141, and a second air duct 11b (as indicated by a dotted arrow in fig. 4, which also indicates the direction of air flow in the second air duct 11 b) between the main unit 2 and the second cover plate portion 142. Thus, by arranging the air channels 11, and the air channels 11 are respectively positioned at different positions, heat at different positions can be transmitted to the air outlet 10 to be discharged through the air channels 11, so that the heat dissipation effect can be improved.

In order to precisely control the cooling effect caused by the air flow through the first air duct 11a and the second air duct 11b, the first air duct 11a and the second air duct 11b may be sealed, respectively, such that the first air duct 11a and the second air duct 11b are at least partially not communicated. The sealing manner of the first air duct 11a may be approximately as follows:

in an alternative embodiment, the host 2 abuts against the first cover plate portion 141 to seal the first air duct 11a, so that the cold air entering the first air duct 11a through the first air inlet 12 and the hot air flow in the first air duct 11a can be prevented from being dispersed between the host 2 and the second cover plate portion 142.

In another alternative embodiment, a first sealing member (not shown) may be disposed between the main unit 2 and the first cover portion 141 to seal the first air duct 11 a. The first sealing member may include one or more of foam, silicone, or gum, so that sealing of the first air duct 11a is achieved with the first sealing member.

In yet another alternative embodiment, the host 2 may abut against the first cover portion 141, and a first sealing member may be further disposed between the host 2 and the first cover portion 141 to seal the first air duct 11 a.

The second air duct 11b may be sealed in the following manner:

In an alternative embodiment, the host 2 abuts against the end of the second cover plate 142 away from the first cover plate 141 to seal the second air duct 11b, so that the cold air entering from the second air inlet 12 and the air flow in the second air duct 11b can be prevented from being transmitted between the first cover plate 141 and the host 2, and thus heat is prevented from being dispersed between the host 2 and the first cover plate 141.

In another alternative embodiment, a first seal may be provided between the host 2 and an end of the second cover portion 142 remote from the first cover portion 141 to seal the second air duct 11 b. The first seal may comprise one or more of foam, silicone, or gum, such that sealing of the second air duct 11b is achieved with the first seal.

In yet another alternative embodiment, the host 2 may abut against the second cover portion 142, and a first seal may be further disposed between the host 2 and the second cover portion 142 to seal the second air duct 11 b.

By sealing the first air duct 11a and the second air duct 11b respectively, the first air duct 11a and the second air duct 11b are at least partially independent, so that different positions of the first air duct 11a and the second air duct 11b can be utilized, and the heat source on the host 2 can be arranged corresponding to different positions of the air ducts 11 according to the arrangement, so that the cooling effect generated when the air flow passes through different air ducts 11 can be accurately controlled.

In some embodiments, the first and second air ducts 11a, 11b may have a blend zone 111 (see fig. 3), and the wind (or air flow (mixture of wind and heat)) of the first and second air ducts 11a, 11b may blend at the blend zone 111. In other words, the first air duct 11a and the second air duct 11b are partially independent and then are fused at the fusion area 111, so that the form and the size of each air duct 11 can be independently designed according to different heat sources, and further, the cooling effect generated by different airflows passing through different air ducts 11 can be controlled.

In an alternative embodiment, the fusion zone 111 may be disposed adjacent to the air inlet 12, such that the first air duct 11a and the second air duct 11b may share the air inlet 12, and the air inlet of the air inlet 12 may flow to the first air duct 11a and the second air duct 11b, respectively, via the fusion zone 111. In other words, the first air duct 11a and the second air duct 11b are integrated at the front section of the air intake and are independent at the rear section, so that the form and the size of each air duct 11 can be designed conveniently and independently, and the wind resistance, the wind pressure, the ventilation quantity and the like of each area can be changed, so that the cooling degree of each area in the first shell 1 and each heat source of the host 2 can be controlled accurately.

In another alternative embodiment, the fusion zone 111 may be disposed adjacent to the air outlet 10, such that the first air duct 11a and the second air duct 11b may share the air outlet 10, and the air outlet (or air flow) of the first air duct 11a and the second air duct 11b may flow to the air outlet 10 through the fusion zone 111. In this way, the front sections of the air inlet of the first air channel 11a and the second air channel 11b are mutually independent, and the rear sections are fused near the air outlet position, so that the form and the size of each air channel 11 can be conveniently and independently designed, and the wind resistance, the wind pressure, the ventilation quantity and the like of each area can be effectively changed.

It will be appreciated that in other embodiments, two or more of the individual air channels 11 may be combined in advance and then combined with the other air channels 11 again. For example, at least one of the first duct 11a and the second duct 11b may include a first sub-duct corresponding to the air inlet 12 and a second sub-duct 11 corresponding to the air outlet 10, and the fusion zone 111 may be located between the first sub-duct and the second sub-duct. In this way, independent design of the individual channels may be facilitated.

It can be understood that the sequence and the position of the fusion of two or more sub-channels in each independent air duct 11 can be adjusted according to practical situations, for example, the arrangement situation of the heat source position of the host 2 in the first housing 1, which is not limited in this embodiment.

In addition, in other embodiments, the individual air channels 11 may be fused first, for example, near the air inlet 12, and then the air channels 11 may be separated again according to the arrangement of the heat source position of the host 2 in the first housing 1, so as to conduct heat to other areas, thereby averaging the overall temperature of the main body device 100.

Of course, in other embodiments, the independent air ducts 11 may be integrated first, then the air ducts 11 are separated again according to the arrangement of the heat source positions of the main unit 2 in the first housing 1, the air quantity of one of the air inlets 12 is split into a plurality of air flow channels, and the re-divided air flows pass through the heat source area requiring cooling and then are integrated at the air outlet 10.

In practical applications, the first air inlet 121 may be disposed at a middle position of the first cover portion 141, the second air inlet 122 may be disposed at a middle position of the second cover portion 142, and one or more of the first air inlet 121 and the second air inlet 122 may be disposed.

In this arrangement, the external air can enter the plurality of independent air channels 11 through the plurality of air inlets 12, then the plurality of air channels 11 are fused according to the arrangement of the heat source positions of the host 2 in the first housing 1, then the air channels are separated into the independent air channels 11, and finally the independent air channels 11 are discharged out of the host 2 through the plurality of air outlets 10.

Specifically, the lens group 204 may include two or more lenses, the lens group 204 may be disposed in the opening of the sidewall structure 203, and the lens group 204 is close to the opening of the upper surface 203a of the sidewall structure 203, and the lens group 204 is used for receiving the light emitted by the optical light source and transmitting the light onto the first optical unit 205. The first optical unit 205 may be disposed at the lower opening of the sidewall structure 203 and cover the lower opening of the sidewall structure 203, and the first optical unit 205 may be a beam splitter, which may be disposed obliquely with respect to the optical axis of the lens assembly 204, so as to reflect light onto the second optical unit 206.

Alternatively, the extension 207 may be entirely provided as a light shielding material.

In some embodiments, to fix the optical bench support 20c in the first housing 1, the optical bench support 20c further includes two locking ends 208, where the two locking ends 208 may be located at two ends of the optical bench support 20c, and each locking end 208 is connected to a corresponding extension 207, and the locking ends 208 may be used for locking with the first housing 1, so that the optical bench support 20c may be fixed in the first housing 1. Specifically, the locking end 208 may be disposed protruding from an outer surface of the extension 207 near the end of the optical bench 20c, and a locking screw hole may be disposed on the locking end 208, through which a fastener (for example, a screw or a bolt) may be fixed to the first housing 1. It will be appreciated that in other embodiments, the locking end 208 may be fixed to the first housing 1 by an adhesive, and the optical bench support 20c may be fixed to the first housing 1.

In some embodiments, the optical bench support 20c further includes a fixing support 209, the fixing support 209 may be connected to at least one of the supporting portion 201 or the connecting portion 202, the host 2 may further include a camera assembly 24, and the camera assembly 24 may be fixed on the fixing support 209. Specifically, the fixing bracket 209 may be disposed on the connecting portion 202, specifically, may be disposed on one side edge of the connecting portion 202, and the image capturing assembly 24 may be disposed on the fixing bracket 209, so that the image capturing assembly 24 is disposed in a region near the middle of the optical machine bracket 20c, and the optical machine assembly 20 is disposed in a region near both ends of the optical machine bracket 20c, and the image capturing assembly 24 may also be used as a heat source of the host 2 because the image capturing assembly 24 generates heat during operation. The camera assembly 24 is disposed on the fixing support 209 of the connection portion 202, and the optical mechanical assembly 20 is disposed at two ends of the optical mechanical support 20c, so that the heat source of the host 2 can be distributed at different positions of the whole machine, and the problem of operation failure of the host 2 caused by too concentrated heat is avoided.

It will be appreciated that, in order to be able to timely dissipate the heat generated by the camera assembly 24 and the opto-mechanical assembly 20, the channel should at least partially pass through the area where the camera assembly 24 and the opto-mechanical assembly 20 are located.

Further, the camera assembly 24 may include one or more.

In an alternative embodiment, the fixing bracket 209 may include a first fixing bracket 209a connected to the connection portion 202 and located between the two support portions 201, and the camera assembly 24 may include a first camera assembly 241, and the first camera assembly 241 may be mounted on the first fixing bracket 209 a. Alternatively, the first camera assembly 241 may include one or more cameras that may provide the same or different functionality. For example, taking the first camera assembly 241 as an example, two cameras, where both cameras may provide the same functionality, e.g., both may implement modeling functionality, or may provide different functionality, e.g., one camera provides modeling functionality and the other provides shooting functionality.

In another alternative embodiment, the camera assembly 24 may further include a second camera assembly 242, and the fixing bracket 209 further includes a second fixing bracket 209b disposed at a side of the support portion 201 remote from the connection portion 202, that is, the second fixing bracket 209b is disposed at a position of the support portion 201 near an end thereof, and the second camera assembly 242 may be mounted on the second fixing bracket 209 b. The second camera assembly 242 may also include one or more, for example, two second camera assemblies 242 may be provided, and then two second fixing brackets 209b may be provided, where two second fixing brackets 209b are respectively disposed on a side of the two supporting portions 201 away from the connecting portion 202, and two second camera assemblies 242 are respectively mounted on the two second fixing brackets 209 b. The second camera assembly 242 can also include one or more cameras, and the plurality of cameras of the second camera assembly 242 can provide the same or different functionality. For example, the second camera assembly 242 may include two cameras, which may be fish-eye lenses, and since the second camera assembly 242 is disposed near the end of the supporting portion 201, it may acquire environmental information near the end of the first housing 1 for processing.

In yet another alternative embodiment, the camera assembly 24 may include both a first camera assembly 241 and a second camera assembly 242, and the fixing bracket 209 may include a first fixing bracket 209a disposed on the connection portion 202 and a second fixing bracket 209b disposed on a side of the support portion 201 remote from the connection portion 202, and the first camera assembly 241 may be mounted on the first fixing bracket 209a and the second camera assembly 242 may be mounted on the second fixing bracket 209 b. The manner in which the camera assembly 24 includes both the first camera assembly 241 and the second camera assembly 242 can implement different functions, and improve the functional diversity of the main body apparatus 100. In addition, the first camera component 241 is disposed at the middle position of the optical machine support 20c, and the second camera component 242 is disposed at the end position of the optical machine support 20c, so that the camera components 24 can be separately disposed, and the situation that the heat is too concentrated to possibly affect the operation when the first camera component 241 and the second camera component 242 are disposed together and simultaneously operate is avoided. In addition, since the air outlet 10 is disposed at the end position of the first casing 1, the second camera assembly 242 is disposed at the end position, so that heat can be quickly conducted out through the air outlet 10, and the heat dissipation effect is improved.

In some embodiments, as shown in fig. 13 to 14, in order to timely guide the wind of the wind channel 11 out to the wind outlet 10 for discharging, and simultaneously concentrate the heat generated by the host 2 to the wind outlet 10, the host 2 may further include a heat dissipation fan 26, where the heat dissipation fan 26 may be located in the wind channel 11. Specifically, as can be seen from the foregoing, since the two light sources 20a are respectively disposed at two ends of the light machine support 20c, the air outlet 10 includes two air outlets respectively disposed at two ends of the cover 14, and thus the number of the heat dissipation fans 26 can be two, and the two heat dissipation fans 26 can be respectively mounted at two ends of the light machine support 20 c. The two heat dissipation fans 26 are arranged, so that the air flow in the air duct 11 can be guided to the air outlet 10 for being discharged, and the heat dissipation efficiency is improved.

Further, the cooling fan 26 may be disposed adjacent to the air outlet 10, so that the wind of the air duct 11 may be guided to the air outlet 10 to be discharged. Specifically, the cooling fan 26 may be a suction fan, which may form a negative pressure at the air outlet 10, so as to draw the air flow in the air duct 11 and the heat generated by the host 2 to the cooling fan 26, so as to concentrate at the air outlet 10 for discharging. In other words, since the cooling fan 26 of the present embodiment is a suction fan, when the external air enters the first housing 1 from the air inlet 12, the external air is sucked by the negative pressure of the cooling fan 26, passes through the components (such as the opto-mechanical component 20 and the control component 22) of the host 2 along the air duct 11, and transfers the heat generated by the operation of the opto-mechanical component 20 and the control component 22 to the cooling fan 26, so as to be discharged through the air outlet 10.

In some embodiments, the side of the supporting portion 201 facing away from the connecting portion 202 and the first housing 1 enclose a circulation space 201a, and the air duct 11 may include the circulation space 201a, so that the heat dissipation fan 26 may be located in the circulation space 201a or disposed adjacent to the circulation space 201a. Specifically, the supporting portion 201 may further include a connecting plate 201b connected to a side of the sidewall structure 203 away from the connecting portion 202, and the connecting plate 201b, an outer surface of the sidewall structure 203, and the first housing 1 enclose the circulation space 201a. Thus, by arranging the connection plate 201b such that the circulation space 201a is formed at the connection plate 201b, the air flows of the channels can be converged thereto, thereby being sucked by the heat dissipation fan 26 and guided to the air outlet 10 to be discharged, and improving the heat dissipation effect.

In actual installation, the cooling fan 26 may be disposed on a side of the supporting portion 201 away from the connecting portion 202, the air outlet side 26b of the cooling fan 26 is opposite to the air outlet 10, and the air inlet side 26a of the cooling fan 26 may be disposed toward the supporting portion 201. Specifically, the heat dissipation fan 26 may be disposed at a side of the sidewall structure 203 away from the connection portion 202, and the heat dissipation fan 26 is disposed vertically. In this case, the air intake side 26a of the heat radiation fan 26 may be opposite to the connection plate 201 b. In this way, the space at the end of the optical bench support 20c can be used to provide the cooling fan 26, so that the overall structure of the host 2 is more compact. It will be appreciated that in other embodiments, the cooling fan 26 may be disposed laterally, i.e., the cooling fan 26 may be disposed on a side of the connection plate 201b away from the sidewall structure 203, and the air inlet side 26a of the cooling fan 26 may be opposite to the sidewall structure 203.

In some embodiments, in order to fix the cooling fan 26 on the optical engine support 20c, a protruding portion 201c is disposed on a side of the supporting portion 201 facing away from the connecting portion 202, and a step structure is formed between the protruding portion 201c and the supporting portion 201, so that the cooling fan 26 can be at least partially disposed on and supported by the step structure, and the air outlet 10 is located on a side of the cooling fan 26 facing away from the protruding portion 201 c. Specifically, the protruding portion 201c may be disposed at a side of the connection plate 201b away from the sidewall structure 203, and the protruding portion 201c may specifically form a stepped structure with a side of the connection plate 201b, so that at least a portion of the heat dissipation fan 26 may be supported.

In some embodiments, to further fix the heat dissipating fan 26, the host 2 may further include an auxiliary bracket 28, where the auxiliary bracket 28 is disposed on the supporting portion 201 and is located in the circulation space 201a, and the heat dissipating bracket is located on a side of the auxiliary bracket 28 and the supporting portion 201 away from the connecting portion 202. Specifically, the auxiliary bracket 28 may be disposed on the connection plate 201b, so that the auxiliary bracket 28 and the protruding portion 201c together form a supporting structure for supporting the heat dissipation fan 26, and fixing the heat dissipation fan 26 on the bare engine bracket 20c is achieved.

Alternatively, the auxiliary bracket 28 may be disposed on the connecting plate 201b by screwing or by bonding, clamping, welding, or the like. For ease of installation, the auxiliary bracket 28 may be fixed to the connection plate 201b by screws.

It will be appreciated that in other embodiments, the auxiliary bracket 28 may be formed as a unitary structure with the connection plate 201b, so that the auxiliary bracket 28 and the projection 201c may also be formed as a unitary structure, which may reduce the assembly process of the components.

Further, the auxiliary bracket 28 includes a ventilation portion 28a and a guiding portion 28b connected to the ventilation portion 28a, the ventilation portion 28a may be located between the guiding portion 28b and the supporting portion 201, the ventilation portion 28a may have an air inlet hole 281, the guiding portion 28b may have an air outlet hole 282, and the air entering the ventilation space 201a may sequentially enter the cooling fan 26 through the air inlet hole 281, the space between the guiding portion 28b and the supporting portion 201, and the air outlet hole 282, and then be guided to the air outlet 10 through the cooling fan 26. In other words, at the circulation portion 28a and the guide portion 28b of the auxiliary bracket 28, through the air inlet hole 281, the space between the guide portion 28b and the support portion 201, and the air outlet hole 282, a circulation passage of the air flow can be formed, so that the air flow in the passage can be conveniently and rapidly circulated thereto and sucked into the heat dissipation fan 26, thereby guiding the air outlet 10 by the heat dissipation fan 26.

In some embodiments, since the cooling fan 26 is a suction fan, in order to enable negative pressure to be formed at the cooling fan 26 to quickly draw the air flow in the channel to the fan hot air fan, each connection between the cooling fan 26 and the supporting portion 201 needs to be sealed to form negative pressure.

In an alternative embodiment, at least one of the side of the cooling fan 26 facing away from its own air inlet side 26a and the side of the cooling fan 26 facing away from its own air outlet side 26b may be provided with a second seal (not shown) for sealing of the air duct 11. Specifically, the second sealing member may be disposed on the side of the cooling fan 26 facing away from the air inlet side 26a thereof, and on the side of the cooling fan 26 facing away from the air outlet side 26b, so as to prevent the air flow in the air duct 11 from being emitted from these positions, and affect the air guiding of the cooling fan 26. The second seal may include one or more of a backing, foam, and silicone, for example.

In another alternative embodiment, a third seal 283 may be further provided on the surface of the guide portion 28b remote from the cooling fan 26 for sealing the air passage 11. The third seal 283 may also be one or more of a gum, foam, or silicone, for example.

In yet another alternative embodiment, a fourth seal 284 is also provided between the side of the guide portion 28b remote from the connection portion 202 and the first housing 1 for sealing of the air duct 11. The fourth seal 284 may also be one or more of a backing, foam, or silicone, for example.

In still another alternative embodiment, a third sealing member may be provided on a surface of the guide portion 28b remote from the cooling fan 26, and a fourth sealing member may be provided between a side of the guide portion 28b remote from the connection portion 202 and the first housing 1 for sealing the air duct 11.

In summary, in either of the above modes, the purpose is to achieve sealing of the air duct 11, and to avoid the situation that the air flow of the air duct 11 is already dispersed to other positions when not sucked into the heat dissipating fan 26, and the heat dissipating effect is affected.

The distribution of the channels and how the cooling fan 26 directs the air flow of the air duct 11 to the air outlet 10 will be briefly described below in connection with the above-described components.

As can be seen from the foregoing, the air duct 11 includes the first air duct 11a and the second air duct 11b, the first air duct 11a is located between the host 2 and the first cover plate portion 141, the second air duct 11b is located between the host 2 and the second cover plate portion 142, specifically, the first air duct 11a may pass through the main circuit board 22a, the side of the light source 20a facing the first frame portion 13, and the second air duct 11b may pass through the main circuit board 22a, the auxiliary circuit board 22b, and the side of the light source 20a facing the cover portion 14, and then, during heat dissipation, air enters the first housing 1 through the first air inlet and the second air inlet, is transferred into the above-mentioned fusion area 111 (or the circulation space 201 a) through the first air duct 11a and the second air duct 11b, respectively, and then is blown toward the air outlet 10 through the heat dissipation fan 26. Therefore, mutual independence (i.e., sealing) between the first air channel 11a and the second air channel 11b is a key to ensure efficient operation of the two air channels 11.

Therefore, in this embodiment, the first sealing member is disposed between the first cover plate portion 141 and the host 2, and the first sealing member is disposed between the host 2 and the second cover plate portion 142, so that the first air duct 11a and the second air duct 11b can be kept independent from each other at the air inlet position, so that heat interference is avoided, and meanwhile, the sealing of the connection position between the cooling fan 26 and the channel (i.e. the periphery of the cooling fan 26) is the last seal of the air duct 11, so that the second sealing member is disposed on the side, facing away from the air inlet side 26a, of the cooling fan 26 and the side facing away from the air outlet side 26b, and then the third sealing member 283 is disposed on the surface, facing away from the cooling fan 26, of the guide portion 28b, facing away from the connection portion 202, and the fourth sealing member 284 are further disposed between the first casing 1, and the sealing of the first air duct and the second air duct is fully realized through the arrangement of the second sealing member, the third sealing member 283 and the fourth sealing member 284, so that the sealing performance of the air duct 11 of the suction cooling fan 26 is ensured, and the air duct efficiency is further ensured.

In some embodiments, to limit the fixing of the heat dissipation bracket on the optical bench bracket 20c to avoid the detachment of the heat dissipation bracket from the optical bench bracket 20c, the host 2 may further include a limiting member 29, at least one end of the limiting member 29 may be fixed on the auxiliary bracket 28, and the limiting member 29 is connected to an end of the heat dissipation bracket away from the protruding portion 201c to limit the heat dissipation fan 26. Specifically, the limiting member 29 may be a limiting strip similar to a concave shape, and the limiting member 29 may enclose with the auxiliary bracket 28 to form a limiting space, so as to limit the position of the end of the cooling fan 26 away from the protruding portion 201c, and prevent the cooling fan from being separated from the protruding portion 201c and the auxiliary bracket 28.

As shown in connection with fig. 15, in some embodiments, the control assembly 22 may be at least partially disposed on the connection 202. To facilitate the positioning of the control assembly 22, the connecting portion 202 may be provided with a boss 202a having a hollow opening, and the control assembly 22 may be at least partially disposed in the hollow portion of the boss 202 a. Specifically, the control assembly 22 may include a main circuit board 22a, where the main circuit board 22a may be disposed on the boss 202a of the connection portion 202, that is, the main circuit board 22a is located on a side of the light source 20a away from the light source 20, so that the main circuit board 22a and the light source 20 are disposed in a reasonable layout, and are distributed in several directions of the whole machine, at least a portion of the air duct 11 may pass through an area where the main circuit board 22a is located, and may also pass through an area where the light source 20 is located, so that the air duct 11 may discharge heat generated by the main circuit board 22a and heat generated by the light source 20a to the air outlet 10. On the other hand, the main circuit board 22a is disposed on the side of the light source 20a away from the light source 20, which can also avoid the main circuit board 22a from shielding the light emitted by the light source 20 a.

It will be appreciated that the main circuit board 22a refers to a motherboard of the head-mounted device, which is mainly used to control the operation and processing of each functional device in the head-mounted device, and thus, a plurality of main chips for controlling the operation and processing of each functional device in the head-mounted device may be disposed on the main circuit board 22 a.

In view of the high number of functional devices in the main body apparatus 100, the control assembly 22 further includes a secondary circuit board 22b electrically connected to the primary circuit board 22a, and the secondary circuit board 22b may be located between the two optomechanical light sources 20a in order to be able to meet the wiring requirements of the devices of the host 2. Specifically, the secondary circuit board 22b and the main circuit board 22a may be connected by the flexible circuit board 22c, and the secondary circuit board 22b and the main circuit board 22a may be formed in a bent structure when connected by the flexible circuit board 22c, that is, the overall area (e.g., length, width) of the main circuit board 22a may be larger than the overall area (e.g., length, width) of the secondary circuit board 22b, the secondary circuit board 22b may be connected to the middle portion of the main circuit board 22a by the flexible circuit board 22c, and a space may be formed between the secondary circuit board 22b and the main circuit board 22a, that is, the secondary circuit board 22b may be located under the main circuit board 22a, and a plurality of secondary chips may be disposed on the secondary circuit board 22 b. In the wiring process, the secondary circuit board 22b is disposed in the hollow portion of the boss 202a of the connection portion 202, and is disposed close to the first camera module 241, so that the first camera module 241 can be electrically connected to the secondary circuit board 22b, and the electrical connection manner can be achieved through a wire, a flexible circuit board, a connector or the like. Since the main circuit board 22a is longer than the sub circuit board 22b, both ends of the main circuit board 22a may be extended to a position near the two light sources 20a, and thus the two light sources 20a may be electrically connected to the main circuit board 22a, and at the same time, the two second image pickup assemblies 242 disposed at both ends of the supporting portion 201 may be electrically connected to the main circuit board 22 a.

In order to avoid heat accumulation between the above components, one or more of the sub-circuit board 22b and the first image pickup assembly 241, the main circuit board 22a and the light source 20a, and the light source 20a and the second image pickup assembly 242 may be provided with heat sinks, so that heat may be conducted by the heat sinks to avoid heat accumulation.

In some embodiments, to support and secure the secondary circuit board 22b, the control assembly 22 may further include a secondary board support 22d, which secondary board support 22d may be located between the connection 202 and the secondary circuit board 22b and used to support the secondary circuit board 22b. Specifically, the sub-plate holder 22d may be provided in the hollow portion of the boss 202a on the connection portion 202. The sub-board support 22d is disposed in the hollow portion of the boss 202a on the connection portion 202, so that the space in the height direction of the optical machine support 20c can be utilized, thereby making the arrangement of the optical machine support 20c and the sub-board support 22d in the first housing 1 more compact and reducing the occupation of the space of the first housing 1.

As shown in connection with fig. 16 to 17, in some embodiments, the main body device 100 further includes a heat dissipation module 4, and the heat dissipation module 4 may include a heat dissipation base 41, and the heat dissipation base 41 may be located between the main circuit board 22a and the sub circuit board 22b, for dissipating heat from the main circuit board 22a and the sub circuit board 22b. Specifically, the heat dissipation base 41 may be an elongated plate, which may be disposed on the optical bench 20c, and the length direction of the heat dissipation base 41 may be along the length direction of the optical bench 20 c. The heat dissipation base plate 41 may extend to the positions of the two supporting portions 201 of the optical machine support 20c, and the heat dissipation base plate 41 may include an upper surface 410 and a lower surface 411 opposite to each other, so that the main circuit board 22a may be attached to the upper surface 410 of the heat dissipation base plate 41, and the sub circuit board 22b may be attached to the lower surface 411 of the heat dissipation base plate 41, so that heat generated by the main chip and the negative chip on the main circuit board 22a and the sub circuit board 22b may be conducted by using the heat dissipation base plate 41, thereby realizing effective heat dissipation of the main circuit board 22a and the sub circuit board 22b.

Further, the heat dissipation module 4 may further include two heat dissipation fin structures 42, the two heat dissipation fin structures 42 are respectively disposed on two ends of the heat dissipation base plate 41, the two heat dissipation fin structures 42 and the heat dissipation base plate 41 may enclose a receiving area 412, and the main circuit board 22a may be located in the receiving area 412. In this way, the heat generated by the main chip and the sub chip on the main circuit board 22a and the sub circuit board 22b is conducted to the heat dissipation fin structure 42 by the heat dissipation bottom plate 41, thereby further improving the heat dissipation effect.

Alternatively, the two fin structures 42 may be attached to the heat dissipating base plate 41 by an adhesive. It will be appreciated that in other embodiments, the two fin structures 42 may be attached to the heat sink base 41 by screws or other fastening means (e.g., snap fit).

In addition, in order to improve the efficiency of the heat radiating base plate 41 in conducting heat to the heat radiating fin structure 42, a heat conducting sheet (for example, a graphite sheet) may be further disposed between the heat radiating fin structure 42 and the heat radiating base plate 41 to improve the heat conducting efficiency.

Alternatively, the two heat dissipation fin structures 42 may be disposed corresponding to the two light sources 20a, so that the two heat dissipation fin structures 42 can timely dissipate the heat generated by the two light sources 20 a. In actual setting, since the heat dissipation base plate 41 is disposed on the light engine support 20c, and may be disposed on the connecting portion 202 and the supporting portion 201, when the two heat dissipation fin structures 42 are disposed on two ends of the heat dissipation base plate 41, the two heat dissipation fins may be located above the two light engine light sources 20a (i.e. the backlight ends of the light engine light sources 20 a).

Specifically, the heat dissipation fin structure 42 includes a plurality of fins 420 disposed at intervals, a heat dissipation channel 421 is formed between two adjacent fins 420, the heat dissipation channel 421 may be in communication with the air duct 11, or may be a part of the air duct 11, in other words, the heat dissipation channel 421 may be in communication with the air inlet 12, so that heat of the main circuit board 22a and the auxiliary circuit board 22b is transferred to the heat dissipation fin 420 structure 42 through the heat dissipation bottom board 41, and is concentrated to the heat dissipation channel 421, and heat generated by the light source 20a of the optical engine is directly transferred to the heat dissipation channel 421 through the heat dissipation fin 420 structure 42, and then enters the air duct 11 through the heat dissipation channel 421, and is finally sucked to the air outlet 10 by the heat dissipation fan 26 for being discharged.

Specifically, in the present embodiment, since the heat dissipation fin structure is disposed on the optical machine support 20c, that is, the heat dissipation fin structure is closer to the first cover plate portion 141 of the first housing 1, the heat dissipation channel 421 between two fins adjacent to each heat dissipation fin structure is actually formed as a part of the air duct 11, so that the external air enters the first housing 1 through the air inlet 12, and the heat generated by the optical machine light source 20a, the main circuit board 22a, and the sub circuit board 22b is pushed along the heat dissipation channel 421 to move toward the heat dissipation fan 26, so that the heat can be attracted by the heat dissipation fan 26 and discharged from the air outlet.

It can be seen that, in addition to the design of the air duct 11, the heat transmission paths of the optical engine light source 20a, the main circuit board 22a and the secondary circuit board 22b are also designed correspondingly, and are mainly implemented by the heat dissipation base plate 41 and the heat dissipation fin structure 42, and the channels pass through the heat dissipation base plate 41 and the heat dissipation fin structure 42, so that the channels can be successfully merged with the heat dissipation channels 421 of the heat dissipation fin structure 42.

In addition, in the present embodiment, the main circuit board 22a, the sub circuit board 22b and the light source 20a are arranged in the vicinity of the heat dissipation base plate 41 and the heat dissipation fin structure 42 in a concentrated manner, so that heat can be conveniently and rapidly conducted out, and heat dissipation efficiency is effectively improved.

In some embodiments, the heat dissipation bottom plate 41 and the heat dissipation fin structure 42 may be made of aluminum alloy, magnesium lithium alloy, or the like, so as to have good heat conduction and heat dissipation properties. In addition, the heat dissipation bottom plate 41 and the heat dissipation fin structure 42 made of aluminum alloy, magnesium aluminum alloy and magnesium lithium alloy are light and thin in overall and light in weight, so that the overall weight of the main body device 100 can be reduced, and the main body device 100 is lighter in overall.

It can be appreciated that in other embodiments, in addition to the above-mentioned combination of the heat dissipation base plate 41 and the two heat dissipation fin structures 42, the heat dissipation module 4 of the present application may further add a VC (Vapor Chamber) vapor chamber on the heat dissipation base plate 41 or add a water cooling system (for example, a water cooling system is disposed on the heat dissipation base plate 41), which can also achieve an effective heat dissipation effect.

In some embodiments, as shown in fig. 18 to 19, to facilitate the installation of the heat dissipating module 4, the heat dissipating base 41 and the light engine support 20c may be locked together by a first fastener 413, and the heat dissipating base 41 and the main circuit board 22a may be locked together by a second fastener 414, so as to connect the heat dissipating module 4 and the light engine support 20c and the main circuit board 22a together. Specifically, in order to enhance the locking effect, the first fastening member 413 may be locked together with the two supporting portions 201 of the optical bench support 20c through two ends of the heat dissipation base plate 41, while the second fastening member 414 may be locked together through the main circuit board 22a and the heat dissipation base plate 41, and in order not to affect the connection between the sub circuit board 22b and the heat dissipation base plate 41, the second fastening member 414 may also be locked together with two ends of the heat dissipation base plate 41 through two ends of the main circuit board 22 a. It will be appreciated that in other embodiments, the heat dissipation plate 41 may be attached to the opto-mechanical bracket 20c and the main circuit board 22a by bonding or snap-fitting.

Wherein, the first fastener 413 and the second fastener 414 can be screws or bolts.

In order to further lock the heat dissipation module 4 and the main circuit board 22a, the heat dissipation module 4 further includes a platen bracket 43, where the platen bracket 43 includes a first platen portion 430 and a second platen portion 431 that are connected to each other, the first platen portion 430 and the main circuit board 22a are locked to the heat dissipation base plate 41 by the third fastener 430a, and the second platen portion 431 and the main circuit board 22a are locked to the heat dissipation base plate 41 by the fourth fastener 431 a. Specifically, the first pressing plate 430 and the second pressing plate 431 are substantially elongated and connected to form an approximately L-shaped structure, the first pressing plate 430 presses the main circuit board 22a against the heat dissipation base plate 41 through the third fastening member 430a, and the second pressing plate 431 presses the main circuit board 22a against the heat dissipation base plate 41 through the fourth fastening member 431a, so that connection stability between the main circuit board 22a and the heat dissipation base plate 41 is effectively ensured.

More specifically, an end cover of the first pressing plate 430 is disposed on a side of the main circuit board 22a away from the optomechanical assembly and is locked with the main circuit board 22a by the third fastener 430a, and the first pressing plate 430 is further bent and pressed against and covered on one side of the main circuit board 22a, the optomechanical assembly and the heat dissipation module 4. One end of the second pressing plate 431 is connected to the other end of the first pressing plate 430, and abuts against and covers the surface of the main circuit board 22a far away from the optical mechanical assembly, and the other end of the second pressing plate 431 is further locked with the middle portion of the heat dissipation bottom plate 41 through a fourth fastener 431 a.

Alternatively, the third fastener 430a and the fourth fastener 431a may be screws or bolts.

It is understood that the number of the platen supports 43 may be one or more, for example, two platen supports 43 may be provided, and two platen supports 43 may be respectively pressed and disposed at both ends of the heat dissipation base plate 41. Of course, the platen support 43 may also be three, four or more.

In a specific arrangement, the main circuit board 22a, the heat dissipation base 41 and the optomechanical support 20c are generally mounted as follows:

the heat dissipation base plate 41 is fixed to the optical machine support 20c through the first fastening member 413 and the second fastening member 414, then the main circuit board 22a is placed on the heat dissipation base plate 41, and then the first pressing plate portion 430 and the second pressing plate portion 431 press the main circuit board 22a on the heat dissipation base plate 41 through the third fastening member 430a and the fourth fastening member 431a, respectively, so that connection between the main circuit board 22a and the heat dissipation base plate 41, and connection between the heat dissipation base plate 41 and the optical machine support 20c are completed.

As shown in fig. 20, the main body device 100 further includes a nose pad assembly 5, and the nose pad assembly 5 includes a supporting blade 51, a nose pad bracket 52 connected to the supporting blade 51, and a mounting portion 53 connected to an end of the nose pad bracket 52 remote from the supporting blade 51, wherein the mounting portion 53 is mounted to the first housing 1 or the mounting portion 53 can extend into the first housing 1 to be mounted to the host 2. Specifically, the mounting portion 53 may include a clamping block, and the first housing 1 or the host 2 includes a clamping groove, where the clamping block is detachably clamped with the clamping groove.

In an alternative embodiment, the mounting portion 53 may be mounted to the first housing 1 by forming a slot in the first housing 1 into which the mounting portion 53 extends, so that the mounting portion 53 is mounted to the first housing 1.

In an alternative embodiment, the mounting portion 53 may be bonded to the first housing 1.

In yet another alternative embodiment, the mounting portion 53 may extend into the first housing 1 for mounting connection with the host 2. Specifically, a clamping groove into which the mounting portion 53 extends is provided on the first housing 1, and the clamping groove can be communicated to the optical machine support 20c of the host 2, so that the mounting portion 53 can be fixed with the optical machine support 20c, the mounting stability of the mounting portion 53 and the first housing 1 is improved, and the mounting portion 53 is prevented from falling out of the first housing 1.

In this embodiment, considering that the sub-board support 22d is provided on the optical bench support 20c, in order to further improve the installation stability of the installation portion 53, the clamping groove on the first housing 1 may also extend to the sub-board support 22d, so that the installation portion 53 extends from the first housing 1 to connect with the optical bench support 20c and the sub-board support 22 d.

The following describes the channel and heat source conditions of the main body device 100 of the first embodiment as follows:

the two ends of the cover portion 14 are respectively provided with a first air outlet 10a and a second air outlet 10b, the first air outlet 10a and the second air outlet 10b are respectively provided with a heat dissipation fan 26, the first cover plate portion 141 and the second cover plate portion 142 are respectively provided with a first air inlet 121 and a second air inlet 122, the first air duct is located between the first cover plate portion 141 and the host 2, and sequentially passes through one side of the main circuit board 22a facing the first frame portion 13, the heat dissipation bottom plate 41, the heat dissipation fin structure 42, the light engine light source 20a and the second image capturing assembly 242, and the second air duct is located between the second cover plate portion 142 and the host 2, sequentially passes through one side of the main circuit board 22a facing the cover portion 14, the heat dissipation bottom plate 41, the first image capturing assembly 241, the heat dissipation fin structure 42, the light engine light source 20a and the second image capturing assembly 242, so that heat of the main circuit board 22a, the light engine light source 20a and the second image capturing assembly 242 is attracted to the fusion area 111 through the first air duct 11a by the heat dissipation fan 26, and simultaneously passes through the first air duct 11a, the heat dissipation bottom plate 20a, the first light source 20a and the second air duct 11b is attracted to the fusion area 111, and the second air duct 11b is further attracted to the fusion area 11 through the heat dissipation bottom plate 41, and the second air duct 20 b sequentially passes through the side of the main circuit board 22a facing the heat towards the cover portion 14.

With the main body device 100 of the first embodiment, the heat dissipating fan 26 is disposed at the position of the air outlet 10, and the air outlet 10 is located at the end of the first housing 1, so that the main circuit board 22a and the auxiliary circuit board 22b can be disposed at the middle position of the optical machine support 20c, i.e. corresponding to the middle position of the first housing 1, and thus, the main circuit board 22a and the optical machine light source 20a can be communicated into a whole by using one heat dissipating module 4, so that the maximum heat dissipating effect can be achieved by using the minimum number of air channels 11. Meanwhile, the length of the air duct 11 can be increased, so that flowing air contacts with a heat source as much as possible, and the heat dissipation efficiency is improved. In addition, the active air suction mode adopted by the cooling fan 26 is utilized, so that heated air of each heat source is not mixed together, and therefore, the heat sources with different temperatures can be cooled respectively and are not interfered with each other.

Further, the cooling fans 26 are disposed at two ends of the optical engine support 20c, so that a middle space region of the optical engine support 20c can be reserved for the first camera module 241, thereby being beneficial to the coordination of the appearance design of the main body device 100.

Further, the heat sources (i.e. the main circuit board 22a, the secondary circuit board 22b, the first camera module 241, the light source 20a of the light engine, and the second camera module 242) are reasonably distributed on the heat dissipation base plate 41 and the heat dissipation fin structure 42, specifically, the main circuit board 22a and the secondary circuit board 22b are respectively arranged on the upper surface and the lower surface of the heat dissipation base plate 41, so that heat can be directly conducted through the heat dissipation base plate 41, then the light source 20a of the light engine is connected through the heat dissipation base plate 41, and then the heat is conducted to the heat dissipation fin structure 42 above the light source 20a of the light engine, thereby achieving the purpose of rapid heat dissipation and temperature reduction in a small volume.

Further, since the first air duct 11a and the second air duct 11b are sealed independently before the fusion area 111, the air volume and the air pressure of each air duct 11 can be flexibly controlled by changing the shape, the wind resistance, the size of the air duct 11 and the like of the first air duct 11a and the second air duct 11b, and the temperature of each area requiring cooling, through which the air duct 11 passes, can be accurately controlled.

Fig. 24 is a schematic structural diagram of another head mounted device 1000, shown according to an example embodiment. The integrated circuit module 1004 in the headset 1000 shown in fig. 24 includes a plurality of interface modules, for example, the plurality of interface modules may be an I2C interface module 10040, an SPI interface module 10041, an I2S interface module 10042, a SLIMBus interface module 10043, and an MIPI interface module 10044, respectively.

The I2C interface module 10040 communicates with the connected modules using an I2C bus, which is a simple, bi-directional two-wire synchronous serial bus. It requires only two wires to transfer information between devices connected to the bus. The master is used to initiate bus transfer of data and generate a clock to open the transferred devices, any addressed device being considered a slave. The relationship of master and slave, transmit and receive on the bus is not constant but depends on the direction of data transfer at this time. If the master device is to send data to the slave device, the master device first addresses the slave device, then actively sends the data to the slave device, and finally the master device terminates the data transfer; if the master device is to receive data from the slave device, the slave device is addressed by the master device first, then the master device receives data sent from the slave device, and finally the master device terminates the receiving process. In this case, the master is responsible for generating the timing clock and terminating the data transfer. Typically I2C is the control interface for transmitting control signaling.

SPI interface module 10041 communicates with the connected modules using an SPI bus. The SPI bus is a high-speed full duplex synchronous communication bus. The SPI communication principle is simple and works in a master-slave mode, which typically has a master device and one or more slave devices, requiring 4 wires for the master device data input, master device data output, clock signal transmission, and enable signal transmission of the master device output, respectively. Typically the SPI interface is also a control interface for transmitting control signaling.

The I2S bus is a bus standard established for audio data transmission between digital audio devices (e.g., CD players, digital audio processors, digital television sound systems). The design of independent wires for transmitting clock and data signals is adopted, and by separating the data and clock signals, distortion induced by time difference is avoided, so that the cost for purchasing professional equipment for resisting audio jitter is saved for users, and the method is widely applied to various multimedia systems. The standard I2S bus cable consists of 3 serial conductors: 1 is a Time Division Multiplexed (TDM) data line; 1 is a word select line; 1 is a clock line.

The SLIMBus interface module 10043 communicates with the connected modules using a SLIMBus bus. The SLIMBus bus is an audio interface designated by the MIPI alliance for interfacing a baseband/application processor and an audio chip, and is typically used for transmitting audio data. The SLIMBus bus is composed of an interface device and one to a plurality of functional devices, the interface device and the functional devices are connected by one to a plurality of ports, and the ports can be input-only, output-only or bidirectional. The SLIMBus bus supports dynamic stopping and restarting, and supports all sampling frequencies.
