[0098] When the main front shell 11 and the main rear shell 12 are buckled, the mounting plate 122 is connected to the top plate 111 through the buckle structure 1223 and the buckle structure 1116; the first part 112 and the bottom plate 121 are connected through the buckle structure 1124 and the buckle structure 1214. The buckle structure 1223 and the buckle structure 1116 and the buckle structure 1124 and the buckle structure 1214 are connected to each other, so that the product can be disassembled for later maintenance, and the weight of the product can be increased by using too many screws for assembly. In addition, in order to strengthen the connection between the main front shell 11 and the main rear shell 12, the top plate 111 and the bottom plate 121 can also be fixed by screws, bolts, etc.

[0099] The buckle structure 1116 and the buckle structure 1223 may constitute a first connection mechanism disposed between the top plate 111 and the mounting plate 122, and the buckle structure 1124 and the buckle structure 1214 may constitute a second connection mechanism disposed between the bottom plate 121 and the first side plate, and the first connection mechanism and the second connection mechanism enable the main front shell 11 and the main rear shell 12 to cooperate to form a receiving chamber 17 for receiving a host of the head mounted device 100. In other embodiments, the first connection mechanism may be a threaded connection structure or a bonding structure, and the second connection mechanism may be a threaded connection structure or a bonding structure.

[0100] It should be noted that when the first shell assembly 10 is described alone (that is, when described without combining with the second shell assembly 30 ), its main front shell 11 may also be referred to as the first shell, and its main rear shell 12 may also be referred to as the second shell.

[0101] The mask 13 of the first housing component 10

[0102] See also Fig.10 and Fig.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 left-right symmetrical first mask portion 1311, a second mask portion 1312 and a connecting portion 1313 located between the first mask portion 1311 and the second mask portion 1312.

[0103] The first mask portion 1311 and the second mask portion 1312 have optical properties of light transmittance, and at least the two through holes 1132 corresponding to the second part 113 of the main front shell 11 meet the light transmittance performance, so as to achieve the following performance: external light can pass through the first mask portion 1311 and the second mask portion 1312, and the human eye cannot see the object inside the mask 13 from the outside. For example, by processing the mask 13 to reduce its light transmittance, a semi-transparent effect is achieved, so that the human eye cannot see the structure inside the mask 13, but the camera assembly 70 can receive external light from the inside of the mask 13, so as to be able to image the external objects, etc. The material of the mask 13 may include plastic or hardware, etc.

[0104] The connecting portion 1313 is provided with a through hole 1314 at the through hole 1131 corresponding to the second portion 113. The mounting portion 132 extends backward from the edge of the mask portion 131, that is, extends toward the main front shell 11. One or more snap structures 1321, such as hooks or bosses, may be provided at the edge of the mounting portion 132 away from the mask portion 131. One or more guide structures 1322, such as horizontally extending bosses or steps, may be provided on the inner surfaces of both sides of the mounting portion 132. These snap structures 1321 and guide structures 1322 are respectively used to cooperate with the snap structures 1141 and guide structures 1142 of the connecting portion 114 of the main front shell 11, so as to install the mask 13 on the main front shell 11, for example, to make the first mounting portion 132 fit the connecting portion 114 of the first side plate. When observed from the front of the mask 13, the coverage area of ​​the mask 13 is larger than the coverage area of ​​the main front shell 11. Thus, when the mask 13 is mounted on the main front shell 11, only the upper portion of the mask 13 is closely connected to the first side plate of the main front shell 11 and covers the first side plate (for example, the upper portion of the mask portion 131 is covered on the second portion 113 of the first side plate), while the lower portion of the mask 13 is lower than the main front shell 11, that is, extends downward beyond the main front shell 11 (see Figure 4 ), and correspondingly exceeds the bottom plate 121. A protective space is formed between the rear cover 14 and the lower portion of the mask 13 to protect the waveguide sheet 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.

[0105] The buckle structure 1321 of the mask 13 and the buckle structure 1141 of the connecting portion 114 may constitute a connecting structure between the edge of the first mounting portion 132 away from the mask portion 131 and the connecting portion 114, and the buckle structure 1321 is engaged with the buckle structure 1141. The guide structure 1322 of the mask 13 and the guide structure 1142 of the connecting portion 114 may constitute a guiding structure between the surface of the first mounting portion 132 facing the connecting portion 114 and the connecting portion 114, and the guide structure 1322 is slidably matched with the guide structure 1142.

[0106] The lens assembly 133 may 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 arranged, and the second through hole 1335 and the third through hole 1336 are located on 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 through hole 1335 and the third through hole 1336, respectively, and a through hole 1339 located between the two lens portions. The second lens 1333 may be combined on the front surface of the lens holder 1331 by a bonding member 134. An annular flange 1337 surrounding the first through hole 1334, the second through hole 1335 and the third through hole 1336 may be further provided on the front surface of the lens holder 1331. The protruding length of the annular flange 1337 may be equal to the thickness of the second lens 1333, so that the second lens 1333 may be accommodated in the space surrounded by the annular flange 1337. The lens holder 1331 may be combined with the rear surface of the connecting portion 1313 by means of an adhesive member 135, and the annular flange 1337 may be inserted into the through hole 1314. The adhesive members 134 and 135 may be double-sided adhesives or the like.

[0107] 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 ; and the two lens portions 1338 are opposite to the second through hole 1335 and the third through hole 1336 , respectively.

[0108] The rear cover 14 of the first housing assembly 10

[0109] See also Fig.12 , the back cover 14 may be transparent, and may include a light-transmitting portion 141 and a mounting portion 142. The light-transmitting portion 141 is optically configured to have light-transmitting properties, so that the light emitted by the optical-mechanical assembly 60 can pass through the light-transmitting portion 141 and enter the user's eyes. The light-transmitting portion 141 may be arranged approximately parallel to the mask portion 131 of the mask 13. The mounting portion 142 extends backward from the edges of the light-transmitting portion 141 except the upper edge, that is, extends in a direction away from the mask 13, and a flange 1421 is formed outwardly from the edge of the mounting portion 142 away from the light-transmitting portion 141. Please also refer to Figure 5 , the rear cover 14 can be assembled with the lower part of the mask 13 and is correspondingly located below the bottom plate 121; wherein, the rear cover 14 can be moved toward the mask 13 so that the light-transmitting portion 141 and the mounting portion 142 are inserted into the lower part of the mask 13 until the flange 1421 abuts against the end surface of the mounting portion 132 of the mask 13 (see also Fig. 20The back cover 14 may also be coated with adhesive at the portion in contact with the mask 13 and the main back shell 12 to strengthen the connection. Fig.14 ) usually contains glass material, which is relatively fragile. Therefore, the waveguide sheet 63 is protected from both the outside and the inside by the mask 13 and the back cover 14, so that safety is high and the user's eyes are not injured by accidentally breaking the glass material. In addition, the back cover 14 can be fully transparent, and its light transmittance is higher than that of ordinary transparent materials, so that the user can clearly see the image displayed by the waveguide sheet 63 after wearing the head mounted device 100.

[0110] The main housing decoration member 15 of the first housing assembly 10

[0111] See also Fig.13 The main shell decoration 15 can be crescent-shaped as a whole, and its top surface 151 can be streamlined or smooth, etc., to increase the aesthetics of the product appearance. The main shell decoration 15 can be set on the top plate 111 to cover the top plate 111, that is, to cover the top of the main front shell 11, so the main shell decoration 15 can also be called a cover plate; and 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. Combined with Figure 5 , one or more button holes 152 may be provided on both sides of the main shell decoration 15, and the number of the button holes 152 is the same as the number of the side buttons 16; for example, two button holes 152 are provided at the left front position of the main shell decoration 15, and two button holes 152 are provided at the right front position of the main shell decoration 15. These button holes 152 are provided correspondingly to the receiving portion 1113 on the top plate 111 of the main front shell 11. The four side buttons 16 are respectively provided above the receiving portion 1113 of the top plate 111, and partially protrude from the main shell decoration 15 through the button holes 152 of the main shell decoration 15, so that the user can press the side buttons 16 to adjust various parameters of the head mounted device 100. Since the four side buttons 16 are approximately located at the left front and right front positions of the first shell assembly 10, it is convenient for the user to operate and use them. A groove 154 is further formed in the center of the inner side surface 153 of the main shell decoration 15. The lower surface 155 of the main shell decoration piece 15 is provided with one or more protruding columns 156 protruding downwards, and these protruding columns 156 may have threaded holes. As mentioned above, the main shell decoration piece 15 is used to be placed in the space defined by the top plate 111 of the main front shell 11 and the ridge portion 1125; wherein, the protruding columns 156 of the main shell decoration piece 15 may pass through the through holes 1114 on the top plate 111 to be fixed to the top plate 111 of the main front shell 11.

[0112] Return to reference Figure 4 and Figure 5As shown, when the first housing assembly 10 is assembled, the main front housing 11 and the main rear housing 12 are assembled together by engaging the buckle structures 1124, 1116, 1214, and 1223 thereon. The mask 13 can be covered in front of the main front housing 11 by engaging the buckle structures 1321 and 1141. The rear cover 14 can approach the mask 13 and be inserted into the lower part of the mask 13. The main housing decoration 15 is then installed and covered on the top of the main front housing 11.

[0113] Optical mechanical components 60

The optical-mechanical assembly 60 may include an optical-mechanical bracket 61, an optical machine 62, and a waveguide sheet 63.

[0115] The optical 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 .

[0116] The top plate 611 can be arranged horizontally. It should be noted that the top plate 611 does not have to be arranged in a continuous and flat plate shape. It can have a recessed portion at one or more locations to reduce the structural weight while meeting the support strength. One or more through holes 6111 can be provided on the top plate 611 for installation with other components. These through holes 6111 may have threads or no threads. One or more long strip through holes 6112 can also be provided at the front position of the top plate 611 for the FPC to pass through. The side plate 612 extends downward from the front edge of the top plate 611, and the two legs 613 are respectively located on the left and right sides of the top plate 611 and extend downward. The side plate 612 has a through hole 6121 and a through hole 6122 at the middle position, and a through hole 6125 and a through hole 6126 are respectively formed on both sides of the middle position of the side plate 612. These through holes 6121, 6122, 6125 and 6126 can be used to insert the camera assembly 70. The through hole 6121 and the through hole 6122 are arranged adjacent to each other, and the distance from the through hole 6121 to the through hole 6126 can be equal to the distance from the through hole 6122 to the through hole 6125. The through holes 6121 and the through holes 6122 correspond to the central through hole 1131 formed on the second part 113 of the main front shell 11 as a whole, and the through holes 6125 and the through holes 6126 correspond to the two through holes 1132 formed on the second part 113 of the main front shell 11 respectively. These through holes 1131 and 1132 are used for external light to be received by the camera assembly to pass through. A through hole 6131 may be defined at the lower end of each supporting leg 613 .

[0117] The number of the optical engines 62 is two, and the number of the waveguide plates 63 is also two. The two optical engines 62 and the two waveguide plates 63 can be arranged on a connector 64, that is, the optical engines 62 and the waveguide plates 63 are fixed by the connector 64. One or more through holes 641 can be provided on the connector 64. These through holes 641 can have threads or no threads. The two optical engines 62 can be symmetrically arranged in the accommodating chamber 17.

[0118] A gasket 65 may be provided below the connector 64. The gasket 65 may be sleeved on the waveguide sheet 63 and abut against the lower surface of the connector 64. The gasket 65 is used to be sandwiched between the connector 64 and the bottom plate 121 of the main rear housing 12 during assembly to prevent the connector 64 from having a hard contact with the main rear housing 12, thereby playing a protective role. The gasket 65 may be made of compressible or elastic materials such as flexible rubber and foam.

[0119] Each optical engine 62 may also be connected to a heat sink 621 in the accommodating chamber 17 to conduct heat conduction connection and heat dissipation to one or more heat sources 622 of the optical engine 62, such as LED lamps. In one embodiment, the heat sink 621 may include a first heat dissipation portion 6211, a second heat dissipation portion 6212, and a third heat dissipation portion 6213.

For example, the third heat dissipation portion 6213 may extend vertically from the connection between the first heat dissipation portion 6211 and the second heat dissipation portion 6212. The second heat dissipation portion 6212 may be connected to one heat source 622 for heat dissipation; the third heat dissipation portion 6213 may be connected to another heat source 622 for heat dissipation. The first heat dissipation portion 6211, the second heat dissipation portion 6212 and the third heat dissipation portion 6213 of the heat sink 621 can be arranged separately from each other, or can be arranged as an integrated structure to facilitate assembly; in addition, the heat sink 621 can also extend into the internal space of the optical-mechanical assembly 60 and / or the first housing assembly 10, and can also dissipate heat to more heat-generating components at the same time by contacting other heat-generating components. For example, the first heat dissipation portion 6211 of the heat sink 621 can extend backward to contact the power FPC 213 of the strap assembly 20 (see Fig.28 ) or the second heat sink 225 is thermally connected (see Fig.33 ). At least one of the heat sink 621 and the second heat sink 225 may include a graphite sheet.

[0120] Each optical engine 62 may be a projector. The optical engine 62 provides light to the waveguide 63, which includes information and / or images for enhancing the user's observation of the material world. The light from the optical engine 62 may be coupled into the waveguide 63, the light undergoes total internal reflection in the waveguide 63, and then the light is coupled out of the waveguide 63 so that the light can be seen by the user.

[0121] During assembly, screws can be passed through the through holes 6111 of the top plate 611 and the through holes 641 of the connector 64, thereby fixing the optical machine bracket 61, the optical machine 62 and the waveguide plate 63 together. It should be noted that in the assembled optical machine assembly 60, a receiving space is defined between the connector 64 and the side plate 612 of the optical machine bracket 61, which is used to receive a part of the camera assembly 70.

[0122] Please refer again Fig.15 , which shows Fig.14 Another perspective view of the optical machine support 61 of the optical machine assembly 60. Fig.15 As shown, on the rear side of the side plate 612, and on both sides of the middle position where the through holes 6121 and 6122 are defined, a slot 6123 and a contact portion 6124 are respectively provided, and the position of the slot 6123 can be higher than the position of the contact portion 6124. The contact portion 6124 can have a flat surface and can be provided with a threaded hole. On the rear side of the side plate 612, and on one side of the position where the through hole 6125 is defined, a slot 6127 is provided, and on the other side of the position, a slot 6128 and a contact portion 6129 are provided. The slot 6128 and the contact portion 6129 can be directly adjacent. The top of the slot 6127 is flush with the top 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 contact portion 6129 can have a flat surface and can be provided with a threaded hole. The position of the slot 6128 may be higher than the position of the abutment portion 6129. On the rear side of the side plate 612, at the position where the through hole 6126 is defined, there are slots and abutment portions that are the same or similar to the slots 6127, 6128 and abutment portion 6129, which will not be described in detail herein.

[0123] Camera assembly 70

[0124] Please refer to Fig.16 , which shows the camera assembly 70 of the head mounted device 100 in the embodiment of the present application. The camera assembly 70 is mounted on the optomechanical bracket 61 of the optomechanical assembly 60 and may include a TOF (Time of flight, TOF for short) camera 71, an RGB camera 72, two fisheye cameras 73, a first camera bracket 74 for fixing the TOF camera 71 and the RGB camera 72, and two second camera brackets 75 for fixing the two fisheye cameras 73 respectively.

[0125] 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 both connected to the FPC 713. The light emitting module 711 has a front end portion, which can also serve as the front end portion of the TOF camera 71. The heat sink 714 is connected to the FPC 713, for example, it is attached to the rear surface of the FPC 713 to dissipate heat. The heat sink 714 has a rear side surface, which can also serve as the rear side surface of the TOF camera 71. When the TOF camera 71 is working, the light emitting module 711 is used to emit a modulated light beam, which is received by the light receiving module 712 after being reflected by the target object. The light receiving module 712 can obtain the flight time of the light beam in space by demodulation, and then calculate the distance of the corresponding target object. Therefore, through the TOF camera 71, when the user wears the head-mounted device 100 and walks around in an environment such as a room, the shape and model of the room can be modeled; that is, by measuring the distance from each point to the head-mounted device 100 worn by the user, the shape and model of the room where the user is located can be determined, thereby constructing a scene.

[0126] The RGB camera 72 can be used to collect two-dimensional color images, capture the color difference of the image, etc. It is connected to the TOF camera 71 and can be fixed by the first camera bracket 74. The RGB camera 72 may include a camera body 721 and an FPC 722. The camera body 721 has a front end, which can also serve as the front end of the RGB camera 72. The camera body 721 is connected to the FPC 722. The FPC 722 and the FPC 713 can be connected together at the upper end. The heat sink 714 can also be connected to the FPC 722, for example, by being attached to the rear surface of the FPC 722 to dissipate heat. The rear side of the heat sink 714 can also serve as the rear side of the RGB camera 72.

[0127] The front end of the TOF camera 71 and the RGB camera 72 may also be provided 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 optical machine bracket 61 during assembly to prevent the TOF camera 71 and the RGB camera 72 from making hard contact with the optical machine bracket 61, thereby playing a protective role. The gasket 76 may be made of compressible or elastic materials such as flexible rubber and foam.

[0128] 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 front end portion, which can also serve as the front end 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 mounting plate 732 also has a rear side surface; the FPC 733 or the camera mounting plate 732 can be arranged close to the second camera bracket 75, and in this case, the corresponding rear side surface thereof can serve as the rear side surface of the fisheye camera 73. The camera mounting plate 732 may include a main body portion 7321, a first plug-in portion 7322 and a second plug-in portion 7323. The main body portion 7321 is used to carry the camera body 731. For example, the camera body 731 can be fixed to the main body portion 7321 by a glue dispensing process or screws. The first plug-in portion 7322 and the second plug-in portion 7323 are respectively located on both sides of the main body portion 7321. In the up-down direction, the first plug-in portion 7322 and the second plug-in portion 7323 may be located at the middle and upper position of the main body 7321, that is, the connection position between the first plug-in portion 7322 and the second plug-in portion 7323 and the main body 7321 is close to the top of the main body 7321. The side of the first plug-in portion 7322 may include a semi-cylindrical portion, and the side of the second plug-in portion 7323 may also include a semi-cylindrical portion.

[0129] In one embodiment, the TOF camera 71 and the RGB camera 72 are arranged 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 can be mainly used for imaging. Of course, the position arrangement of these cameras is not limited to this, and it 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.

[0130] Different cameras and different arrangement positions can make the imaging principles and effects different. For example, the four cameras, TOF camera 71, RGB camera 72 and two fisheye cameras 73, can complement each other; among them, the fisheye camera 73 has a larger shooting angle and can be a wide-angle camera, but its resolution can be relatively low. The resolution of the RGB camera 72 can be relatively high, but its shooting angle can be relatively small. By combining the RGB camera 72 and the fisheye camera 73, a relatively clear image with a larger shooting angle can be formed.

[0131] The first camera bracket 74 is located behind the TOF camera 71 and the RGB camera 72 to mount the two TOF cameras 71 and the RGB camera 72 on the optical-mechanical bracket 61 of the optical-mechanical assembly 60. The first camera bracket 74 may include a middle portion 741, a plug-in portion 742, and a fixing portion 743. The middle portion 741 has a pressing surface facing the TOF camera 71 and the RGB camera 72, and the pressing surface may include two flat surfaces, namely a first flat surface 7411 and a second flat surface 7412. The plug-in portion 742 and the fixing portion 743 are respectively located on both sides of the middle portion 741; wherein, in the up-down direction, the plug-in 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 position of the plug-in portion 742 may be higher than the position of the fixing portion 743. The side of the plug-in portion 742 may include a semi-cylindrical portion to facilitate rotation in the card slot 6123. The fixing portion 743 has a through hole 744.

[0132] The two second camera brackets 75 are symmetrically arranged and are respectively located behind the two fisheye cameras 73. Each second camera bracket 75 may include a middle portion 751, a plug-in portion 752 and a fixing portion 753. The middle portion 751 is connected between the plug-in portion 752 and the fixing portion 753, and is arranged away from the fisheye camera 73 from the plug-in portion 752 and the fixing portion 753. The plug-in portion 752 and the fixing portion 753 are respectively located on both sides of the middle portion 751. In the up-down direction, the plug-in portion 752 and the fixing portion 753 may be located at the same or different height positions on both sides of the middle portion 751; for example, the plug-in portion 752 may be located in the middle or lower middle position of one side of the middle portion 751, that is, the connection position of the plug-in portion 752 and the middle portion 751 is located between the top and the bottom of the middle portion 751 or close to the bottom of the middle portion 751; the fixing portion 753 may be located in the middle position of the other side of the middle portion 751.

Subsequently, the plug-in portion 752 of the second camera bracket 75 can be inserted into the slot 6127 of the optical machine bracket 61, and a screw is passed through the through hole 754 of the fixing portion 753 and then screwed into the threaded hole of the abutment portion 6129 of the optical machine bracket 61, so that the fisheye camera 73 can be installed on the optical machine bracket 61, and the middle portion 751 is pressed against the rear side of the fisheye camera 73. The plug-in portion 752 of the second camera bracket 75 and the first plug-in portion 7322 of the camera mounting plate 732 are in contact with each other in the slot 6127.

[0135] By fixing the TOF camera 71, the RGB camera 72 and the fisheye camera 73 through the above structure, some fixing screws can be omitted, thereby improving the assembly efficiency.

[0136] Since the TOF camera 71 , the RGB camera 72 and the fisheye camera 73 are all mounted on the optical machine bracket 61 , the optical machine bracket 61 can also be called a mounting base.

[0137] When the camera assembly 70 and the optical-mechanical assembly 60 are assembled in the first shell assembly 10, the front end portion of one fisheye camera 73 is inserted into the through hole 6125 of the optical-mechanical bracket 61, and corresponds to a through hole 1132 of the second part 113 of the main front shell 11, so as to receive external light; the front end portion of the other fisheye camera 73 is inserted into the through hole 6126 of the optical-mechanical bracket 61, and corresponds to another through hole 1132 of the second part 113 of the main front shell 11, so as to receive external light.

[0140] Please refer to Fig.18 and Fig.19, which shows a stereoscopic exploded view of the main board 80, the speaker assembly 91 and the microphone assembly 92 of the head mounted device 100 in an embodiment of the present application.

[0141] The main board 80 is mounted on the optomechanical assembly 60 , and may include a PCB (Printed Circuit Board, collectively referred to herein as PCB) 81 and one or more chips 82 , one or more protective covers 83 , and one or more heat sinks 84 disposed on the PCB 81 .

[0142] The PCB 81 may be a substrate with printed circuits, which can be used as a carrier for electrical connection of electronic components. The chips 82 may be mounted on the PCB 81, and some of the chips 82 may be covered by one or more protective covers 83 for protection. A heat sink 84 may be provided on the outer surface of the protective cover 83 for heat dissipation. The heat sink 84 may be a graphite heat sink.

[0143] Two key FPCs 162 may be connected to the left and right sides of the PCB 81, respectively. Each key FPC 162 may include a connecting section 1621, a key section 1622, and a bending section 1623 disposed between the connecting section 1621 and the key section 1622.

[0146] In one embodiment, the accommodating chamber 17 defined by the first housing assembly 10 may include a first chamber for accommodating the mainboard 80 and a second chamber and a third chamber located at two opposite sides of the first chamber. The first speaker 911 may be located in the second chamber and contact and connect with one end of the mainboard 80, and the second speaker 913 may be located in the third chamber and contact and connect with the other end of the mainboard 80.

[0147] The second speaker 913 may include a sound cavity box 9131 and a speaker body 9132 placed in the sound cavity box 9131. The sound cavity box 9131 is used to provide a certain sound cavity so that the sound emitted by the speaker body 9132 can revolve inside the sound cavity box 9131, thereby providing a good sound effect for the user to hear. The first speaker 911 may have the same structure as the second speaker 913, that is, the first speaker 911 may include a sound cavity box 9111 and a speaker body 9112 placed in the sound cavity box 9111 (see Fig.19 ). The first speaker 911 can be installed at the left rear end of the mainboard 80, and can be connected to the mainboard 80 through a wire or FPC (not shown). Similarly, the second speaker 913 can be installed at the right rear end of the mainboard 80, and can be connected to the mainboard 80 through a wire or FPC (not shown). It is worth noting that when the mainboard 80 and the speaker assembly 91 are assembled in the first shell assembly 10, the first speaker 911 and the second speaker 913 are respectively located at two corners of the first shell assembly 10; the first speaker 911 and the second speaker 913 correspond to the speaker sound outlet 1215 opened on the bottom plate 121 of the first shell assembly 10, which is used to output the sound emitted by the first speaker 911 and the second speaker 913. The first speaker 911 and the second speaker 913 can also be located below the corresponding side button 16, for example, the first speaker 911 corresponds to at least one side button 16 in the direction perpendicular to the top plate 111, and the second speaker 913 corresponds to at least one side button 16 in the direction perpendicular to the top plate 111. Since the spaces at the two corners of the first housing assembly 10 are utilized, the structure is compact and the sound effect can be improved.

[0148] In one embodiment, the microphone assembly 92 may include a first microphone 921 , a second microphone 923 , a third microphone 925 and a fourth microphone 927 , all of which are disposed in the accommodating chamber 17 .

[0149] The first microphone 921 can be connected to the power supply FPC 213 (see Fig.28) is connected to the PCB 81, and the second microphone 923 can be connected to the PCB 81 through an FPC 924. In one embodiment, the first microphone 921 can be connected to the PCB 81 through a wire or a separate FPC. The first microphone 921 and the second microphone 923 can be respectively arranged on both sides of the PCB 81; for example, when the mainboard 80 is installed in the first housing assembly 10, the first microphone 921 corresponds to an outlet 1162 of a channel 1160 at the left front position of the first part 112 of the main front shell 11 to receive external sounds through the channel 1160, and the second microphone 923 corresponds to an outlet 1162 of a channel 1160 at the right front position of the first part 112 of the main front shell 11 to receive external sounds through the channel 1160. The first microphone 921 can also be supported by the first speaker 911 or fixed on the first speaker 911. The second microphone 923 can also be supported by the second speaker 913 or fixed on the second speaker 913.

[0150] The third microphone 925 and the fourth microphone 927 may be disposed at a lower position of the middle portion of the PCB 81, and respectively correspond to the outlets 1242 of the two channels 1240 on the bottom plate 121 of the main rear housing 12, so as to receive external sounds through the two channels 1240 respectively. Since the third microphone 925 and the fourth microphone 927 may be disposed below the PCB 81, a support member 929 may be disposed 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 the support member 929, and the support member 929 may be fixed to the PCB 81. The third microphone 925 may be connected to the PCB 81 via an FPC 926, and the fourth microphone 927 may be connected to the PCB 81 via an FPC 928. In one embodiment, the FPC 926 and the FPC 928 may be connected to the PCB 81 after being joined with the FPC 713 of the camera assembly 70. In other embodiments, the FPC 926 and the FPC 928 may be connected to the PCB 81 separately, or the FPC 926 and the FPC 928 may be combined and then connected to the PCB 81 .

[0151] By arranging the microphone assemblies 92 in this way, they interfere with each other less and their directivities differ more.

[0246] See also Fig.34 and Fig.40 The connector 33 may include a connector body 331 and a side wall 332 extending from an edge of the connector body 331 .

[0247] like Fig.34 and Fig.40As shown, the connector body 331 is generally rectangular, with rounded corners; and it and four side walls 332 form a receiving cavity 333. The connector body 331 is provided with a through hole 3310 for the lacing assembly 20 to pass through. The connector body 331 is provided with a buckle 3313 in the receiving cavity 333, and the buckle 3313 is buckled with the third buckle 3113 of the first channel shell 311 and the third buckle 3213 of the second channel shell 321 respectively. Specifically, the fastener 3313 includes a slot 3315 that snaps into engagement with the protrusion 3114 of the third fastener 3113, a slot 3315 that snaps into engagement with the protrusion 3214 of the third fastener 3213, a snap-fitting piece 3314 that matches the protrusion 3115 of the third fastener 3113, and a snap-fitting piece 3314 that matches the protrusion 3215 of the third fastener 3213.

[0248] After the bottom front shell 31 and the bottom rear shell 32 are buckled together, the main body 3110 of the first channel shell 311 and the main body 3210 of the second channel shell 321 form a channel for the strap assembly 20 to extend into; after the first power shell 312 and the second power shell 322 are matched, the space above the partition plate 3222 can be defined as a first receiving chamber, and the space below the partition plate 3222 can be defined as a second receiving chamber; the first receiving chamber is connected to the channel, and the two can be jointly defined as a first channel; in addition to accommodating the first headband 21 and the second headband 22 that can overlap with each other, the first receiving chamber can also accommodate the tension adjustment mechanism 40 to adjust the length of the overlapping part of the first headband 21 and the second headband 22. Therefore, the entity part constituting the channel and the first receiving chamber can also be defined as a headband and tension adjustment mechanism shell (can also be defined as a first shell); the second receiving chamber is used to accommodate a power source, such as a battery 35, and can be defined as a power shell (can also be defined as a second shell).

[0249] It can be understood that after the bottom front shell 31 and the bottom rear shell 32 are buckled together, the main body 3110 of the first power shell 312, the second power shell 322 and the first channel shell 311 can be defined as a first shell; and the first channel shell 311 and the second channel shell 321 located on both sides of the first shell can be defined as a second shell.

[0250] The above-mentioned various names, such as: channel, receiving chamber, first receiving chamber, second receiving chamber, first shell, second shell, headband and tension adjustment mechanism shell, power supply shell, can be adjusted according to actual conditions. The present application is not limited to the above-mentioned names. The names of similar structures can be interchanged according to actual conditions. For example, the channel can also be called the first receiving chamber. At this time, the original first receiving chamber can be called the second receiving chamber, and the original second receiving chamber can be called the third receiving chamber. The names of the first shell and the second shell can also be interchanged.

The first shell 41 and the second shell are buckled to form a box body, and the main part of the ratchet pawl mechanism 42 can be accommodated in the box body. The two headbands of the strap assembly 20 (i.e., the first headband 21 and the second headband 22) can extend into the box body and overlap and connect to the ratchet pawl mechanism 42, and the length of the first and second headbands 21 and 22 overlapping each other is adjusted by the ratchet pawl mechanism 42; here, the second shell is not a necessary component, and the tension adjustment mechanism 40 can also be formed by only relying on the ratchet pawl mechanism 42 to be installed on the first shell 41.

[0253] The first housing 41 of the tension adjustment mechanism 40

[0254] Please see attached Fig.42 , which discloses three-dimensional views of the first shell 41 at different angles. The first shell 41 may include a shell bottom plate 410. The shell bottom plate 410 may be a rectangular plate with uniform thickness, and a center hole 4100 is disposed at the center thereof.

[0255] The two opposite long sides of the shell bottom plate 410 are formed with side plates 412 facing the second shell (i.e., the bottom rear shell 32), and the height of each side plate 412 gradually decreases from the middle to the sides so that the surface of the side plate 412 facing the second shell is in an arc shape, so as to be in close contact with the second shell. One of the two ends of one side plate 412 is provided with a first columnar mounting portion 413 facing the second shell, and an internal thread can be provided in the first mounting portion 413 so that the first shell 41 is fixed to the bottom rear shell 32 by passing a bolt through the first mounting portion 413. A first buckling structure 4120 is formed in the middle of the side plate 412 provided with the first mounting portion 413. In one embodiment, the first buckling structure 4120 is a groove and a protrusion formed above the groove, so that when the first shell 41 is fixed to the bottom rear shell 32, the protrusion is placed on the bearing rib 3228b to support the first shell 41. A second snap-fitting structure 4122 is formed on the other side plate 412 where the first mounting portion 413 is not formed. In one embodiment, the second snap-fitting structure 4122 is composed of three grooves arranged at intervals and a protrusion formed above a middle groove so that the second snap-fitting structure 4122 can be fastened to the hook 3217 on the bottom rear shell 32 through the groove, thereby completing the fixation of the first shell 41 and the bottom rear shell 32.

[0256] The housing bottom plate 410 is provided with a circular ratchet 414 , reinforcing ribs 415 arranged around the ratchet 414 , and a second mounting portion 416 distributed around the outer periphery of the ratchet 414 on the surface of the housing bottom plate 410 facing the second housing (ie, the bottom rear shell 32 ).

[0258] The reinforcing ribs 415 may include a plurality of parallel first reinforcing ribs 4150 extending from the outer peripheral wall of the ratchet 414 and a plurality of mutually parallel second reinforcing ribs 4152 intersecting the first reinforcing ribs 4150. The first reinforcing ribs 4150 extend from the outer peripheral wall of the ratchet 414 to the edges of the two relatively short sides of the bottom plate 410 of the housing. The height of the first reinforcing ribs 4150 gradually decreases from the outer peripheral wall of the ratchet 414 to the shorter edge of the bottom plate 410 of the housing so that the top surface of the first reinforcing ribs 4150 facing the second housing is in an arc shape as a whole, so as to be buckled with the bottom rear shell 32, so that the first and second headbands 21, 22 extending into the box body are in contact with the first reinforcing ribs 4150, so that the first and second headbands 21, 22 will not be bent at corners. The second reinforcing ribs 4152 are perpendicular to the first reinforcing ribs 4150, that is, they are arranged along the two long sides perpendicular to the bottom plate 410 of the housing.

[0260] See also Fig.41 The ratchet pawl mechanism 42 may include a ratchet 414 formed on the first shell 41, a pawl assembly 420 that cooperates with the ratchet 414 and is accommodated therein, and a knob assembly 430 that is mounted and fixed on the pawl assembly 420 and drives the pawl assembly 420 to rotate and is slidably connected to the center hole 4100.

[0261] See also Fig.43 The pawl assembly 420 includes a first baffle plate 421, a second baffle plate 422 fixedly connected to the first baffle plate 421, a rotating plate 423 located between the first baffle plate 421 and the second baffle plate 422, a first pawl 424, a second pawl 425, a first spring 426 and a second spring 427 assembled on the second baffle plate 422, and a gear 428 fixedly installed on the side of the second baffle plate 422 away from the first baffle plate 421.

[0262] The first baffle plate 421 may be a circular sheet structure, with a central hole 4210 in the middle, the central hole 4210 is aligned with the central hole 4100 in the ratchet 414, and the central axes of the two are the same. The first baffle plate 421 is provided with a first connecting portion 4212 and a second connecting portion 4214 on a side facing the second baffle plate 422, wherein the second connecting portion 4214 is prismatic, and the first connecting portion 4212 is cylindrical, and the outer peripheral walls of the first and second connecting portions 4212 and 4214 are both provided with convex strips, so as to be tightly matched with the corresponding structure on the second baffle plate 422 to fix the first baffle plate 421 and the second baffle plate 422.

[0263] See also Fig.44 The second baffle plate 422 has the same shape and size as the first baffle plate 421, and a center hole 4220 is provided in the middle, and the center hole 4220 is aligned with the center hole 4210 of the first baffle plate 421. The second baffle plate 422 is provided with a first clamping portion 4222 and a second clamping portion 4224 on a side facing the first baffle plate 421. The second clamping portion 4224 has the same shape as the second connecting portion 4214 of the first baffle plate 421, but has a different size, so that the second connecting portion 4214 of the first baffle plate 421 can be inserted into the second clamping portion 4224. The second clamping portion 4224 includes a first clamping wall 4220a and a second clamping wall 4220b provided at a certain angle to the first clamping wall 4220a, that is, the distance between the first clamping wall 4220a and the second clamping wall 4220b gradually increases in the direction outward from the center hole 4220. The first clamping portion 4222 has the same shape as the first connecting portion 4212 of the first baffle 421, but has a different size, so that the first connecting portion 4212 of the first baffle 421 can be inserted into the first clamping portion 4222. A first mounting shaft 4225 for mounting the first pawl 424, a second mounting shaft 4226 for mounting the second pawl 425, a first mounting frame 4227 for mounting the first spring 426, and a second mounting frame 4228 for mounting the second spring 427 are further provided on one side of the second baffle 422 facing the first baffle 421.

[0264] The first baffle 421 and the second baffle 422 can also be used as a mounting part, the second clamping portion 4224 and the second connecting portion 4214 can be used as a limiting portion to cooperate with the rotating plate 423, and can also be used as a fixing portion to fix the first baffle 421 and the second baffle 422 together; the first clamping portion 4222 and the first connecting portion 4212 are used as fixing portions to fix the first baffle 421 and the second baffle 422 together.

[0265] The mounting member is not limited to the assembly of the first baffle plate 421 and the second baffle plate 422, and other forms can be used to make the first pawl 424 and the second pawl 425 contact and cooperate with the ratchet 414; that is, the mounting member has a notch or a structure similar to a notch so that the first pawl 424 and the second pawl 425 can extend out of the space formed by the mounting member and contact and cooperate with the ratchet 414; so the mounting member can also be a box body with a notch or a structure similar to a notch;

[0266] Of course, the mounting member may also be only the first baffle plate 421 or the second baffle plate 422 . For example, the mounting member is the second baffle plate 422 , and the second clamping portion 4224 and the second connecting portion 4214 are formed on the first baffle plate 421 or the second baffle plate 422 as limiting portions.

[0267] The first installation axis 4225 and the second installation axis 4226 are respectively located at two sides of the first clamping portion 4222 , and are symmetrically arranged relative to the first clamping portion 4222 .

[0268] The first installation frame 4227 and the second installation frame 4228 are symmetrically arranged relative to the first clamping portion 4222 , and the shapes, sizes and structures of the two are completely the same.

[0269] See also Fig.44 and Fig.45 The first installation frame 4227 includes a first retaining wall 4227a, a second retaining wall 4227b arranged at a certain angle to the first retaining wall 4227a, and a connecting wall 4227c connecting one end of the first retaining wall 4227a and the second retaining wall 4227b. The first retaining wall 4227a, the second retaining wall 4227b, and the connecting wall 4227c form a receiving space 4227d for receiving the first spring 426. The first retaining wall 4227a is extended from the outer peripheral wall of the first clamping portion 4222, and a clamping shaft 4227e is arranged on the connecting wall 4227c toward the receiving space 4227d, and the first spring 426 is sleeved on the clamping shaft 4227e.

[0270] Since the second installation frame 4228 has the same structure as the first installation frame 4227, it will not be described in detail here, and only its components are listed. The second installation frame 4228 includes a first retaining wall 4228a, a second retaining wall 4228b, a connecting wall 4228c, a receiving space 4228d, and a clamping shaft 4228e. The first retaining wall 4227a of the first installation frame 4227 is connected to the first retaining wall 4228a of the second installation frame 4228, and one end of the connecting wall 4227c is also connected to one end of the connecting wall 4228c.

[0271] It should be pointed out that the first spring 426 and the second spring 427 can also be other elastic parts, such as tension springs, compression springs, objects that provide telescopic force, etc., so that the first pawl 424, the second pawl 425 and the ratchet 414 cooperate to complete the conversion between the engaged and unengaged states; and the corresponding first mounting frame 4227 and the second mounting frame 4228 will also be changed into other structures that can fix the elastic parts according to the different elastic parts.

[0272] The rotating plate 423 is an eccentric wheel structure, which has a through hole 4230. Of course, the rotating plate 423 and the knob assembly 430 can also be integrated at the through hole 4230; the through hole 4230 is aligned with the center hole 4220 of the second baffle 422 and has the same axis. In one embodiment, the inner surface of the through hole 4230 is polygonal, such as a hexagon. The rotating plate 423 has a notch 4232 at one end away from the through hole 4230. The shape of the notch 4232 is the same as that of the first clamping portion 4222 of the second baffle 422, but the size is different. The size of the notch 4232 is larger than the size of the first clamping portion 4222 so as to accommodate the first clamping portion 4222. Here, the second clamping portion 4224 and the second connecting portion 4214 serve as limiting portions to cooperate with the notch 4232; the notch 4232 has two opposite inner walls, namely, a first inner wall 4232a and a second inner wall 4232b arranged opposite to the first inner wall 4232a; the peripheral surface of the rotating plate 423 includes an outer wall surface 4234. When the rotating plate 423 rotates around the axis of the through hole 4230, the rotating plate 423 and the second clamping portion 4224 have only three states: a state in which only the first inner wall 4232a contacts the first clamping wall 4220a, a state in which the rotating plate 423 and the second clamping portion 4224 do not contact each other, and a state in which only the second inner wall 4232b contacts the second clamping wall 4220b; that is, the limiting portion is configured to be in contact with and not in contact with the inner wall surface of the notch 4232 so that the rotating plate 423 rotates around its rotation axis (the axis of the through hole 4230) by a certain angle.

[0273] Please also see Figure 44 to Figure 46 The first pawl 424 is pivotally mounted on the first mounting shaft 4225 of the second baffle plate 422 and can rotate around the first mounting shaft 4225. A pivot hole 4240 is provided at the middle position of the first pawl 424 for pivoting to the first mounting shaft 4225. The first pawl 424 has two opposite ends, namely: a first end 4242 connected to the first spring 426 and a second end 4244 abutting against the outer wall 4234 of the rotating plate 423. A mounting shaft 4242a is provided on the side of the first end 4242 facing the accommodating space 4227d of the first mounting frame 4227 so that the first spring 426 can be sleeved and installed thereon, and an edge 4242b is provided on the side of the first end 4242 facing away from the first mounting frame 4227, and the edge 4242b is used to engage with the inner teeth 4140 of the ratchet 414 (please refer to Fig.47 The second end 4244 has a contact surface 4244a on one side facing the rotating plate 423. In one embodiment, the contact surface 4244a is an arc surface so as to be in linear contact with the outer wall surface 4234 of the rotating plate 423 to reduce the pressure therebetween.

[0274] The second pawl 425 and the first pawl 424 are symmetrically arranged relative to the first clamping portion 4222 of the second baffle 422, and the two have exactly the same shape and structure, which will not be described in detail here, and only the components are listed. The second pawl 425 has a pivot hole 4250, a first end 4252, a second end 4254, a mounting shaft 4252a, an edge 4252b, and a contact surface 4254a.

[0275] When the first spring 426 is installed, one end is sleeved on the clamping shaft 4227e in the first installation frame 4227, and the other end is sleeved on the installation shaft 4242a of the first pawl 424. In this way, the first spring 426 is installed in the first installation frame 4227, and the first pawl 424 can rotate around the first installation shaft 4225. When the first pawl 424 rotates, it drives the first end 4242 of the first pawl 424 to move, thereby pushing the first spring 426 to be compressed to different degrees in the first installation frame 4227.

[0276] The structure and function of the second spring 427 are exactly the same as those of the first spring 426 . The second spring 427 is installed in the second installation frame 4228 , and will not be described in detail herein.

[0277] The outer wall surface 4234 of the rotating plate 423 is a curved surface, and the outer wall surface 4234 is configured such that when the rotating plate 423 rotates around its rotation axis, the outer wall surface 4234 pushes the first and second pawls 424 and 425 to rotate respectively, so that the first and second pawls 424 and 425 and the ratchet 414 complete the conversion between the engaged and unengaged states. Fig.45 , when there is no external force applied to force the rotating plate 423 or the mounting member (the combination of the first baffle plate 421 and the second baffle plate 422) to rotate; due to the action of the first spring 426 and the second spring 427, the rotating plate 423 and the outer surface of the limiting portion (i.e., the outer surface of the second clamping portion 4224) are in a non-contact state, and the pawl assembly 420 and the ratchet 414 are in a clamping state; when the rotating plate 423 is forced to rotate around the axis of the through hole 4230 under the intervention of external force, two states occur:

[0278] (1) It changes from a non-contact state to a state in which only the first inner wall 4232a is in contact with the first clamping wall 4220a. At this time, in the direction in which the rotating plate 423 rotates around the through hole 4230, the distance from the contact position between the first pawl 424 and the outer wall surface 4234 to the through hole 4230 gradually increases, so that the first end 4242 of the first pawl 424 moves and disengages from the inner tooth 4140 on the inner wall of the ratchet 414; while the distance from the contact position between the second pawl 425 and the outer wall surface 4234 to the through hole 4230 gradually decreases, but the ratchet 414 squeezes the second spring 427 of the second pawl 425, so that the second pawl 425 and the inner tooth 4140 on the inner wall of the ratchet 414 are also in a disengaged state; finally, the pawl assembly 420 and the ratchet 414 are disengaged.

[0279] (2) It changes from a non-contact state to a state in which only the second inner wall 4232b is in contact with the second locking wall 4220b. At this time, in the direction in which the rotating plate 423 rotates around the through hole 4230, the distance from the contact position between the second pawl 425 and the outer wall surface 4234 to the through hole 4230 gradually increases, so that the second end 4254 of the second pawl 425 moves and disengages from the inner tooth 4140 on the inner wall of the ratchet 414; the distance from the contact position between the first pawl 424 and the outer wall surface 4234 to the through hole 4230 gradually decreases, but the ratchet 414 squeezes the first spring 426 of the first pawl 424, so that the first pawl 424 and the inner tooth 4140 on the inner wall of the ratchet 414 are also in a disengaged locking state; finally, the pawl assembly 420 and the ratchet 414 are disengaged.

[0280] See also Fig.43 The gear 428 has a central hole 4280, and the central hole 4280 is aligned with the central hole 4220 of the second baffle plate 422 and has the same central axis. The gear 428 is fixedly disposed on a side of the second baffle plate 422 away from the first baffle plate 421.

[0281] See also Fig.48 When the strap assembly 20 is connected to the tension adjustment mechanism 40, one end of the first headband 21 with the length adjustment hole 2103 is stacked with one end of the second headband 22 with the length adjustment hole 2203. At this time, the first saw tooth 2104 and the second saw tooth 2204 are respectively located on the opposite sides of the two stacked length adjustment holes 2103 and 2203, and the gear 428 is placed in the two stacked length adjustment holes 2103 and 2203 and meshes with the first saw tooth 2104 and the second saw tooth 2204.

[0282] See also Fig.49 and Fig.50The knob assembly 430 may include a rotating disk 431 , a first transmission shaft 432 extending from the inner surface of the rotating disk 431 , and a second transmission shaft 433 mounted on the first transmission shaft 432 .

[0283] The side surface of the rotating disk 431 may be a rough structure. In one embodiment, a plurality of grooves arranged in parallel are disposed on the outer surface of the rotating disk 431 to form a convex rib between two adjacent grooves.

[0284] The first transmission shaft 432 and the second baffle 422 have the same central axis, and the first rotating shaft 432 is sequentially formed with a first connecting shaft 4321, a second connecting shaft 4322, and a third connecting shaft 4323 which are coaxially arranged along the central axis direction of the second baffle 422. The first connecting shaft 4321 and the second connecting shaft 4322 are both circular shafts, that is, the outer circumference is circular and the outer diameter of the first connecting shaft 4321 is larger than the outer diameter of the second connecting shaft 4322. The outer circumference of the third connecting shaft 4323 is a polygon, and in one embodiment is a hexagon, and the distance between the center of the hexagon and any side of the hexagon is less than the radius of the second connecting shaft 4322, and a center hole 4324 is provided at the center of the third connecting shaft 4323, and the center hole 4324 has an internal thread.

[0285] The second transmission shaft 433 has the same central axis as the first transmission shaft 432, and is sequentially formed with a coaxially arranged disc 4330, a first connecting shaft 4331 connected to the disc 4330, a second connecting shaft 4332 connected to the first connecting shaft 4331, and a third connecting shaft 4333 connected to the second connecting shaft 4332 along the axial direction away from the rotating disk 431.

[0286] The outer diameter of the disk 4330 is larger than the outer diameter of the first connecting shaft 4331 and the outer diameter of the gear 428. A recess 4330a is provided at the bottom thereof, and a through hole 4330b is provided at the middle position of the recess 4330a. The inner wall of the recess 4330a is polygonal, and in one embodiment is hexagonal, so as to cooperate with the third connecting shaft 4323 of the first transmission shaft 432. When the gear 428 is placed in the two length adjustment holes 2103 and 2203 of the stacked first and second headbands 21 and 22, the disk 4330 cooperates with the gear 428 and the second baffle 422 to limit the first and second headbands 21 and 22, so as to prevent the first and second headbands 21 and 22 from being out of meshing with the gear 428.

[0287] The first connecting shaft 4331 and the third connecting shaft 4333 are both circular shafts, that is, the outer circumference is circular and the outer diameter of the first connecting shaft 4331 is larger than the outer diameter of the third connecting shaft 4333.
