[0042] ​​​​​The terms used in the implementation part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0043] In the related art, after the head-mounted display device is worn on the head of the user, an optical signal can be sent to the eyes of the user to achieve a virtual reality (VR), augmented reality (AR), mixed reality (MR), and the like display effect.

Therefore, how to detect the health status of the user during the use of the head-mounted display device becomes a problem to be solved.

[0044] Therefore, the embodiments of the present application provide a headband assembly 100, a mask assembly 200, and a head-mounted display device. A flexible sensor is arranged in a flexible part of the headband assembly 100 and / or the mask assembly 200 in contact with the head, the pressure between the flexible part and the head or the physiological signal of the head is detected by the flexible sensor, for example, the pressure between the headband assembly 100 and the back of the head, the pressure between the mask assembly 200 and the face, and the physiological signals such as the blood pressure signal, the heart rate signal, the sweat signal, and the temperature signal of the face are detected, the detected data is processed and analyzed, and a health detection report can be output, so that the head-mounted display device has a health detection function. In addition, the flexible sensor can be adapted to the shape of the head in a bending manner, the flexible sensor is in soft cooperation with the head, the flexible sensor can be designed in a large area, the detection area is increased, and the detection accuracy is improved. In addition, the flexible sensor is arranged in the flexible part of the headband assembly 100 and / or the mask assembly 200, the position of the flexible sensor relative to the head can remain unchanged, the stability is increased, and the timeliness and accuracy of the detection are improved.

[0045] The embodiments of the present application provide a head-mounted display device, which can include but is not limited to a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device, and the like.

[0046] Figure 1 A schematic diagram of a head-mounted display device provided by the embodiments of the present application is shown.

[0047] As Figure 1As shown, the head-mounted display device comprises a display device 300, a mask assembly 200 and a headband assembly 100. The headband assembly 100 and the mask assembly 200 are connected to the display device 300 respectively. When the head-mounted display device is worn on the head of a user, the headband assembly 100 is in close contact with the back of the head of the user, and the headband assembly 100 exerts a pressing force on the mask assembly 200 through the display device 300, so that the mask assembly 200 is pressed against the face of the user, and the mask assembly 200 is in close contact with the face of the user. Through the cooperation of the head-mounted assembly and the mask assembly 200, the display device 300 can be more stably worn on the head of the user.

[0048] When the head-mounted display device is worn on the head of the user, the display device 300 is used to send optical signals to the eyes of the user to display images in front of the eyes of the user.

[0049] Exemplarily, referring to Figure 1 As shown, the display device 300 comprises a main body 310 and two temples 320. The first ends of the two temples 320 are connected to the opposite ends of the main body 310, and at this time, the display device 300 formed by the two temples 320 and the main body 310 has a shape similar to a U shape. The second ends of the two temples 320 are detachably connected to the two ends of the headband assembly 100, and at this time, the main body 310, the two temples 320 and the headband assembly 100 can form a closed enclosed structure, so that the head-mounted display device can be wrapped around the head of the user. After the head-mounted display device is worn on the head of the user, the main body 310 is located in front of the eyes of the user, and the main body 310 is used to send optical signals to the eyes of the user.

[0050] The mask assembly 200 has a light shielding function, and the mask assembly 200 is used to form a light shielding space. The optical signals sent by the display device 300 enter the eyes of the user through the light shielding space, which can enhance the immersion of the user.

[0051] Exemplarily, as shown in Figure 1 As shown, the mask assembly 200 is fixedly connected to the main body 310 of the display device 300 and located between the two temples 320, and the mask assembly 200 is used to contact the face of the user to support the main body 310. Specifically, when the user wears the head-mounted display device, the mask assembly 200 contacts the face of the user, and the face of the user supports the main body 310 through the mask assembly 200, so as to more stably fix the main body 310 in front of the eyes of the user.

[0052] Figure 2 For Figure 1 the schematic view of the headband assembly in Figure 3 the cross-sectional schematic view of the headband assembly as shown in Figure 2 Figure 4 the cross-sectional schematic view of the headband assembly as shown in Figure 2 ​A schematic diagram showing the cooperation of the first flexible sensor, the first electrical connector, and the first connecting member. Figure 5 for Figure 2 A schematic diagram of point A in the middle.

[0053] In some possible implementations, the headband assembly 100 includes a flexible strap 110, a first electrical connector 130, and at least one first flexible sensor 120. The opposite ends of the flexible strap 110 are used for detachable connection to the display device 300, specifically, in conjunction with... Figure 1 and Figure 2 It can be seen that the two opposite ends of the flexible strap 110 are detachably connected to the second ends of the two temples 320 of the display device 300, and the flexible strap 110 and the display device 300 are used to form a closed ring structure. When the head-mounted display device is worn on the user's head, the flexible strap 110 contacts the back of the user's head. The first flexible sensor 120 is disposed inside the flexible strap 110 (e.g., Figure 3 As shown, the first flexible sensor 120 is fixedly connected to the flexible band 110, and at least one first flexible sensor 120 is used to detect the pressure between the flexible band 110 and the back of the head. The first electrical connector 130 is used to electrically connect at least one first flexible sensor 120 to the display device 300.

[0054] When the head-mounted display device is worn on the user's head, the display device 300 supplies power to the first flexible sensor 120 via the first electrical connector 130 to ensure the normal operation of the first flexible sensor 120. Simultaneously, the first electrical connector 130 can also transmit data collected by the first flexible sensor 120 to the display device 300. When the first flexible sensor 120 detects pressure between the flexible band 110 and the back of the head, the display device 300 processes and analyzes the detected pressure data, enabling functions such as fatigue detection and comfort adjustment. When the first flexible sensor 120 detects physiological signals such as temperature and sweat on the back of the head, it enables functions such as fatigue detection, health monitoring, and comfort adjustment.

[0055] For example, while the first flexible sensor 120 detects the pressure between the flexible band 110 and the back of the head in real time, the user adjusts the tightness of the flexible band 110 based on the feeling of pressure on the back of the head, ensuring that the effect of the flexible band 110 on the back of the head is within a suitable range, thus achieving comfortable wearing adjustment. Alternatively, the duration of the pressure between the flexible band 110 and the back of the head detected by the first flexible sensor 120 can be used to obtain the total wearing time of the head-mounted display device, achieving wear fatigue detection. Alternatively, the first flexible sensor 120 can be used to detect the temperature of the flexible band 110 or the temperature of the back of the head; the duration of the detected temperature can also be used to obtain the total wearing time of the head-mounted display device, achieving wear fatigue detection.

[0056] Therefore, by detecting the information such as the pressure between the flexible band member 110 and the back of the head, the physiological signals of the back of the head, and the like by the first flexible sensor 120, analyzing and processing the detected information, a health report can be output in real time, and the head-mounted display device is provided with a health detection function. In addition, the first flexible sensor 120 can be adapted to the shape of the back of the head in a bent manner, and thus the first flexible sensor 120 can be designed in a large area, the detection area is increased, and the detection accuracy can be improved, thereby improving the accuracy of detection. Furthermore, by arranging the first flexible sensor 120 on the flexible band member 110 in contact with the back of the head, the position of the first flexible sensor 120 relative to the back of the head can be kept unchanged, the stability of the first flexible sensor 120 is increased, and the timeliness and accuracy of detection are improved. Finally, by arranging the first flexible sensor 120 inside the flexible band member 110, the first flexible sensor 120 is protected, direct contact between the back of the head and the first flexible sensor 120 can be avoided, and the first flexible sensor 120 can be prevented from being worn or falling off.

[0057] Exemplarily, as shown in FIG. 1, the number of the first flexible sensor 120 is one, and at this time, the first flexible sensor 120 is used to detect the pressure between the flexible band member 110 and the back of the head. Figure 4

[0058] Of course, the number of the first flexible sensor 120 can also be more than two, for example, the number of the first flexible sensor 120 can also be two or three.

[0059] When the number of the first flexible sensor 120 is more than one, in one embodiment, any one of the first flexible sensor 120 is used to detect the pressure between the flexible band member 110 and the back of the head. In another embodiment, part of the plurality of first flexible sensors 120 is used to detect the pressure between the flexible band member 110 and the back of the head, and another part of the plurality of first flexible sensors 120 is used to detect the temperature, humidity, and the like of the back of the head. In yet another embodiment, part of the plurality of first flexible sensors 120 is used to detect the pressure between the flexible band member 110 and the back of the head, and another part of the plurality of first flexible sensors 120 is used to detect the temperature or humidity of the flexible band member 110. In still another embodiment, a first part of the plurality of first flexible sensors 120 is used to detect the pressure between the flexible band member 110 and the back of the head, a second part of the plurality of first flexible sensors 120 is used to detect the temperature or humidity of the flexible band member 110, and a third part of the plurality of first flexible sensors 120 is used to detect the temperature, humidity, and the like of the back of the head.

[0060] The first flexible sensor 120 can be a thin film sensor, a sheet sensor, or a fabric sensor, and the like. ​

[0061] When the number of the first flexible sensors 120 is multiple, in an embodiment, the types of all the first flexible sensors 120 can be the same, for example, all the first flexible sensors 120 can be thin film sensors. In another embodiment, the types of all the first flexible sensors 120 can also be different, for example, the number of the first flexible sensors 120 is three, and the types of the three first flexible sensors 120 are thin film sensors, sheet sensors or fabric sensors respectively. In yet another embodiment, the types of a part of all the first flexible sensors 120 can be different, and the types of another part of all the first flexible sensors 120 can be the same, for example, the number of the first flexible sensors 120 is three, and one of the first flexible sensors 120 can be a thin film sensor, and the remaining two of the first flexible sensors 120 can be sheet sensors.

[0062] The flexible band member 110 is made of a flexible material, for example, the flexible band member 110 can be supported by cloth, so that the flexible band member 110 has high flexibility, good air permeability and moisture absorption, thereby improving the wearing comfort.

[0063] In some embodiments, the flexible band member 110 can be made of a flexible wire harness through a 3D weaving process, at this time, the flexible band member 110 is a flexible woven band, so that the flexible band member 110 has good air permeability.

[0064] In other embodiments, the flexible band member 110 can also be formed by splicing two flexible sheets.

[0065] In some possible implementations, the headband assembly 100 further includes a flexible plate member (not shown in the figure) located inside the flexible band member 110. The first flexible sensor 120 is fixedly connected to the flexible plate member, and at least one first flexible sensor 120 is arranged between the flexible plate member and the back of the head and detects the pressure between the back of the head and the flexible plate member. In this way, the first flexible sensor 120 is carried by the flexible plate member, which can further avoid the movement of the first flexible sensor 120 relative to the back of the head, and improve the timeliness and accuracy of detection.

[0066] The flexible plate member is made of a flexible material, for example, the flexible plate member is a silica gel plate or a foam plate.

[0067] In an embodiment, the first flexible sensor 120 can be connected to the flexible plate member by adhesion, for example, the first flexible sensor 120 can be connected to the flexible plate member by glue.

[0068] In another embodiment, the first flexible sensor 120 can also be integrally formed with the flexible plate member. Specifically, the first flexible sensor 120 and the flexible plate member can be integrally formed in a mold by in-mold injection, thereby forming an integrated soft support detection assembly.

[0069] When the number of the first flexible sensors 120 is plural, in an embodiment, any one of the first flexible sensors 120 is located between the flexible plate member and the back of the head, that is, any one of the first flexible sensors 120 is arranged on the surface of the flexible plate member close to the back of the head. In another embodiment, part of the first flexible sensors 120 are located between the flexible plate member and the back of the head.

[0070] In some possible implementations, the headgear assembly 100 further comprises a first posture sensor (not shown in the figure), which is arranged on the flexible band member 110, and the first electrical connector 130 is further used for electrically connecting the first posture sensor and the display device 300.

[0071] When the head-mounted display device is worn on the head of the user, the position and posture of the head of the user are detected by the first posture sensor, the first electrical connector 130 sends the posture signal output by the first posture sensor to the display device 300, and the processor inside the display device 300 processes and analyzes the received posture signal, so as to feed back the cervical posture of the user when wearing the head-mounted display device in real time, and also provide a sitting posture suggestion, thereby realizing cervical health detection.

[0072] In an embodiment, the first posture sensor can be a flexible posture sensor. In another embodiment, the first posture sensor can also be a rigid posture sensor.

[0073] The specific structure of the first posture sensor is not limited here, for example, the first posture sensor can be an inertial sensor.

[0074] In some possible implementations, the first posture sensor is located inside the flexible band member 110, and the flexible band member 110 can protect the first posture sensor, so as to avoid direct contact between the back of the head and the first posture sensor, thereby preventing the first posture sensor from being worn or falling off.

[0075] Of course, in addition to being arranged inside the flexible band member 110, in some embodiments, the first posture sensor can also be arranged outside the flexible band member 110.

[0076] In some possible implementations, as shown in FIG. 6, the first posture sensor 120 is arranged on the surface of the flexible band member 110 close to the back of the head. Figure 4As shown, the first electrical connector 130 includes a first flexible conductive element 131 and a first electrical connector 132. A first end of the first flexible conductive element 131 is used for electrical connection with a first flexible sensor 120 or a first posture sensor. The first electrical connector 132 is electrically connected to a second end of the first flexible conductive element 131 and is used for electrical connection with the display device 300. In this way, the first flexible conductive element 131 can be bent to adapt to the shape of the flexible strip 110, avoiding affecting the use of the flexible strip 110.

[0077] like Figure 4 As shown, the number of first flexible conductive elements 131 is one. Of course, the number of first flexible conductive elements 131 can also be multiple.

[0078] When there are multiple first flexible sensors 120, the first flexible sensors 120 can share a single first flexible conductive element 131. Alternatively, when there are multiple first flexible conductive elements 131, any one of the first flexible conductive elements 131 can be electrically connected to at least one first flexible sensor 120. Furthermore, when both a first flexible sensor 120 and a first attitude sensor are present, the first attitude sensor and the first flexible sensor 120 can be electrically connected to different first flexible conductive elements 131, or the first attitude sensor and at least one first flexible sensor 120 can share the same first flexible conductive element 131.

[0079] The first flexible conductive element 131 can be a flexible cable or a flexible printed circuit (FPC). When there are multiple first flexible conductive elements 131, the structures of the multiple first flexible conductive elements 131 can be the same or different, or some of the multiple first flexible conductive elements 131 can have the same structure and other parts can have different structures.

[0080] In some embodiments, such as Figure 5 As shown, the first electrical connector 132 can be a magnetic PIN or the like. The first electrical connector 132 is used to make electrical contact with the circuit on the temple 320, so as to realize the electrical connection between the first electrical connector 132 and the display device 300.

[0081] In some possible implementations, such as Figure 2 As shown, the headband assembly 100 also includes two first connectors 140. Each end of the flexible band 110 is fixedly connected to a first connector 140. The first connectors 140 are used for detachable connection with the display device 300.

[0082] In some embodiments, the first connector 140 can be a locking assembly, which enables the locking and unlocking of the flexible strap 110 and the temple 320, providing a reliable and easy-to-operate connection and improving the convenience of using the headband assembly 100.

[0083] For example, the locking assembly includes a housing, a resilient snap (not shown in the figure), and an unlocking element, wherein a portion of the housing is provided with a second groove 141 (e.g., Figure 5 As shown, the second groove 141 is used for inserting a portion of the temple 320 and forming a plug-in engagement with the temple 320. A portion of the elastic buckle passes through the housing and extends into the second groove 141, engaging with the portion of the temple 320 that extends into the second groove 141, thereby locking the flexible strap 110 and the temple 320 together. An unlocking member is connected to the elastic buckle, a portion of which extends out of the housing. The unlocking member causes the elastic buckle to retract into the housing, thereby unlocking the flexible strap 110 and the temple 320.

[0084] In some possible implementations, at least one first connector 140 is provided with a first electrical connector 132. For example, one of two first connectors 140 may be provided with a first electrical connector 132. Of course, either first connector 140 may be provided with a first electrical connector 132. In this way, by providing the first electrical connector 132 on the first connector 140, an electrical connection can be achieved between the first electrical connector 132 and the display device 300 when the display device 300 is connected to the headband assembly 100, thereby improving the efficiency of the connection between the display device 300 and the headband assembly 100.

[0085] Understandably, the first electrical connector 132 can be integrated with the first connector 140 as a single unit, which improves both overall compactness and ease of operation. For example... Figure 5 As shown, a portion of the first electrical connector 132 is disposed inside the first connector 140. The contact end of the first electrical connector 132 is located inside the second groove 141 and exposed. When the first connector 140 and the temple 320 are locked together, the circuit on the first electrical connector 132 is connected to the temple 320.

[0086] Figure 6 for Figure 1 A schematic diagram of the face mask components. Figure 7 for Figure 6 The diagram shown is an exploded view of the mask assembly. Figure 8 for Figure 6 The diagram shows a cross-sectional view of the mask assembly.

[0087] In some possible implementations, such as Figure 7As shown, the mask assembly 200 includes a mask 210, a second electrical connector 230, and at least one second flexible sensor 220. The mask 210 includes a flexible contact 211 fixedly connected to the host 310, and the flexible contact 211 is configured to contact the user's face. The second flexible sensor 220 is arranged on the flexible contact 211, and any one of the second flexible sensors 220 is configured to measure the physiological signals of the face or detect the pressure between the mask 210 and the face. The second electrical connector 230 is configured to electrically connect the at least one second flexible sensor 220 to the display device 300.

[0088] When the head-mounted display device is worn on the user's head, the display device 300 supplies power to the second flexible sensor 220 through the second electrical connector 230 to ensure normal use of the second flexible sensor 220. At the same time, the second electrical connector 230 can also transmit the data collected by the second flexible sensor 220 to the display device 300. When the second flexible sensor 220 detects the pressure between the mask 210 and the face, the display device 300 processes and analyzes the detected pressure data to achieve functions such as wearing fatigue detection and wearing comfort adjustment. When the second flexible sensor detects the physiological signals such as the temperature, sweat, heart rate, and blood pressure of the face, the functions such as wearing fatigue detection, health detection, and wearing comfort adjustment can be achieved.

[0089] For example, while the second flexible sensor 220 detects the pressure between the mask 210 and the face in real time, the user adjusts the mask 210 according to the feeling of the mask 210 pressing the face to achieve wearing comfort adjustment. Alternatively, the total duration of the user wearing the head-mounted display device can be obtained by the duration of the pressure detected by the second flexible sensor 220 to achieve wearing fatigue detection. Alternatively, the second flexible sensor 220 is configured to detect the temperature of the face, and the total duration of the user wearing the head-mounted display device can also be obtained by the duration of the detected temperature to achieve wearing fatigue detection. Alternatively, the second flexible sensor 220 is configured to detect the pulse wave signal of the face to achieve heart rate detection and / or blood pressure monitoring.

[0090] Therefore, by detecting the information such as the pressure between the mask 210 and the face, the physiological signals of the face, and the like through the second flexible sensor 220, analyzing and processing the detected information, a health report can be output in real time, so that the head-mounted display device has a health detection function. In addition, the second flexible sensor 220 can adapt to the shape of the face through bending, so that the second flexible sensor 220 can be designed in a large area, increase the detection area, and improve the detection accuracy, thereby improving the accuracy of detection. In addition, by arranging the second flexible sensor 220 on the flexible contact 211 in contact with the face, the position of the second flexible sensor 220 relative to the face can be kept unchanged, the stability of the second flexible sensor 220 is increased, and the timeliness and accuracy of detection are improved.

[0091] Exemplarily, as shown in Figure 7 The number of the second flexible sensor 220 can be one. Of course, the number of the second flexible sensor 220 can also be more than two, for example, the number of the second flexible sensor 220 can also be two or three.

[0092] When the number of the second flexible sensor 220 is multiple, in one embodiment, any one of the second flexible sensor 220 is used to detect the pressure between the mask 210 and the face. In another embodiment, any one of the second flexible sensor 220 is used to measure the physiological signals of the face. In yet another embodiment, part of the multiple second flexible sensors 220 is used to measure the physiological signals of the face, and the other part is used to measure the pressure between the mask 210 and the face.

[0093] In some embodiments, when the number of the second flexible sensor 220 is multiple, at least two of the second flexible sensors 220 are used to detect different to-be-detected signals, which can be blood pressure signals, heart rate signals, pressure signals, sweat signals, and the like, and a variety of health detection can be achieved, such as blood pressure detection, heart rate detection, comfort detection, and sweat detection.

[0094] The second flexible sensor 220 can be a thin film sensor, a sheet sensor, or a fabric sensor, and the like.

[0095] When the number of the second flexible sensors 220 is plural, in an embodiment, the types of all the second flexible sensors 220 can be the same, for example, all the second flexible sensors 220 can be thin film sensors. In another embodiment, the types of all the second flexible sensors 220 can also be different, for example, the number of the second flexible sensors 220 is three, and the types of the three second flexible sensors 220 are thin film sensor, sheet sensor or fabric sensor respectively. In yet another embodiment, the types of a part of all the second flexible sensors 220 can be different, and the types of another part of all the second flexible sensors 220 can be the same, for example, the number of the second flexible sensors 220 is three, and one of the second flexible sensors 220 can be a thin film sensor, and the remaining two of the second flexible sensors 220 can be sheet sensors.

[0096] In an embodiment, the flexible contact 211 can be made of flexible material, for example, made of flexible silica gel or made of foam.

[0097] In some possible implementations, as shown in Figure 7 The mask 210 further includes a bracket 212 for fixed connection with the display device 300, the flexible contact 211 is fixedly connected to the bracket 212, and the at least one second flexible sensor 220 is arranged between the flexible contact 211 and the bracket 212. In this way, arranging the second flexible sensor 220 between the flexible contact 211 and the bracket 212 can protect the second flexible sensor 220, and can avoid direct contact between the face and the second flexible sensor 220, preventing the second flexible sensor 220 from being worn or falling off.

[0098] In an embodiment, in combination with Figure 7 and Figure 8 It can be known that any one of the second flexible sensors 220 is located between the flexible contact 211 and the bracket 212. In another embodiment, a part of the plurality of second flexible sensors 220 is located between the flexible contact 211 and the bracket 212, and another part of the plurality of second flexible sensors 220 is located outside the gap formed by the flexible contact 211 and the bracket 212.

[0099] It should be noted that in addition to being arranged outside the flexible contact 211, in some scenarios, at least one of the second flexible sensors 220 can also be arranged inside the flexible contact 211.

[0100] In some possible implementations, the mask assembly 200 further includes a second pose sensor (not shown in the figure), the second pose sensor is fixedly connected to the mask 210, and the second electrical connector 230 is further used for electrically connecting the second pose sensor and the display device 300.

[0101] When the head-mounted display device is worn on the head of the user, the position and posture of the head of the user are detected by the second posture sensor, the second electrical connecting member 230 sends the posture signal output by the second posture sensor to the display device 300, and the processor inside the display device 300 processes and analyzes the received posture signal, so as to feed back the cervical posture of the user when wearing the head-mounted display device in real time, and also provide a sitting posture suggestion, thereby realizing cervical health detection.

[0102] In an embodiment, the second posture sensor can be a flexible posture sensor. In another embodiment, the second posture sensor can also be a rigid posture sensor.

[0103] The specific structure of the second posture sensor is not limited here. For example, the second posture sensor can be an inertial sensor.

[0104] The specific position of the second posture sensor on the mask 210 is not limited here. For example, the second posture sensor can be arranged on the surface of the flexible contact member 211, or the second posture sensor can be arranged inside the support member 212 of the mask 210.

[0105] In some possible implementations, as shown in Figure 7 The second electrical connecting member 230 includes a second flexible conductive member 231 and a second electrical connector 232. The first end of the second flexible conductive member 231 is used to be electrically connected with the second flexible sensor 220 or the second posture sensor. The second electrical connector 232 is electrically connected with the second end of the second flexible conductive member 231, and the second electrical connector 232 is used to be electrically connected with the display device 300.

[0106] In this way, the second electrical connecting member 230 can adapt to the structure of the mask 210, and ensure that the data detected by the second flexible sensor 220 and the second posture sensor is sent to the display device 300 for processing. In addition, the second flexible conductive member 231 is flexible, which can reduce the difficulty of arranging the second electrical connecting member 230.

[0107] As shown in Figure 7 The number of the second flexible conductive member 231 is one. Of course, the number of the second flexible conductive member 231 can also be multiple.

[0108] When the number of the second flexible sensors 220 is plural, the second flexible sensors 220 can share one second flexible conductive member 231, or the number of the second flexible conductive members 231 is plural, and any one second flexible conductive member 231 can be electrically connected with at least one second flexible sensor 220. In addition, when the second flexible sensor 220 and the second pose sensor exist simultaneously, the second pose sensor and the second flexible sensor 220 can be electrically connected with different second flexible conductive members 231 respectively, or the second pose sensor and at least one second flexible sensor 220 can share the same second flexible conductive member 231.

[0109] The second flexible conductive member 231 can be a flexible cable or a flexible printed circuit (FPC). When the number of the second flexible conductive members 231 is plural, the structures of the plural second flexible conductive members 231 can be the same or different, or the structures of a part of the plural second flexible conductive members 231 are the same and the structures of another part are different.

[0110] In some embodiments, the second electrical connector 232 can adopt a magnetic PIN or the like, and the second electrical connector 232 is used to electrically contact with the circuit on the host 310, so as to realize the electrical connection between the second electrical connector 232 and the display device 300.

[0111] In some possible implementations, the mask 210 further comprises at least two second connecting members 213, for example Figure 7 As shown, the number of the second connecting members 213 is four, and of course, the number of the second connecting members 213 can be less than or more than four. The second connecting member 213 is fixedly connected with the bracket member 212, and the second connecting member 213 is used to be inserted into the first groove of the display device 300 and fixedly connected with the display device 300. Specifically, the second connecting member 213 is inserted into the first groove of the host 310, and the first connecting member 140 is connected with the host 310, so that the connection is reliable and easy to operate, and the convenience of using the mask assembly 200 is improved.

[0112] In some possible implementations, at least one second connecting member 213 is provided with a second electrical connector 232, for example Figure 6 or Figure 8 As shown, one of the plural second connecting members 213 is provided with the second electrical connector 232. In this way, by arranging the second electrical connector 232 on the second connecting member 213, the electrical connection between the first electrical connector 132 and the display device 300 can be realized when the display device 300 is connected with the second connecting member 213, and the efficiency of connecting the display device 300 with the mask assembly 200 is improved.

[0113] It can be understood that the second electrical connector 232 can be arranged in one body with the second connecting piece 213, so as to improve the overall compactness and the operation convenience. For example, part of the second electrical connector 232 is arranged inside the second connecting piece 213, and the contact end of the second electrical connector 232 is located outside the second connecting piece 213 and is used to extend into the inside of the first recess. When the second connecting piece 213 is locked with the host 310, the second electrical connector 232 is in communication with the circuit on the host 310.

[0114] It should be noted that the first flexible sensor 120 and the second flexible sensor 220 can be arranged in the head-mounted display device at the same time, or one of the first flexible sensor 120 and the second flexible sensor 220 is arranged in the head-mounted display device. In addition, the first pose sensor and the second pose sensor can be arranged in the head-mounted display device at the same time, or one of the first pose sensor and the second pose sensor is arranged in the head-mounted display device.
