However, since there are often many accessories in the head-mounted display device, and the fixing accessories of the head-mounted display device are all arranged in the front area and the rear area of the user's head, when the user wears the head-mounted display device, the front area and the rear area of the head will bear more pressure.

[0049] It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0050] Refer to Figure 1 , Figure 1 It is a schematic structural diagram of a head-mounted display device for the hardware operating environment involved in the embodiment solution of this application.

[0051] It should be noted that the head-mounted display device in the embodiment of this application includes, but is not limited to, Mixed Reality (MR) devices (such as MR glasses or MR helmets), Augmented Reality (AR) devices (such as AR glasses or AR helmets), Virtual Reality (VR) devices (such as VR glasses or VR helmets), Extended Reality (XR) devices or some combination thereof, and so on.

[0052] Such as Figure 1As shown in the figure, the head-mounted display device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard. Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a Wireless-Fidelity (WI-FI) interface). The memory 1005 may be a high-speed Random Access Memory (RAM) or a stable non-volatile memory (NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art can understand that Figure 1 the structure shown in the figure does not constitute a limitation on the head-mounted display device, and it may include more or fewer components than shown in the figure, or combine some components, or have a different component layout.

[0054] As Figure 1 shown, the memory 1005, as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a computer program.

[0055] In Figure 1 the head-mounted display device shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with users; the processor 1001 and the memory 1005 in the head-mounted display device of the present application may be disposed in the head-mounted display device. The head-mounted display device calls the computer program stored in the memory 1005 through the processor 1001 and executes the following embodiments.

[0056] Based on the above head-mounted display device, the overall concept of the airbag control method of the present application is provided.

[0057] Users need to wear a head-mounted display device to experience the virtual reality space constructed based on VR / AR technology. However, the head-mounted display devices used in related technologies have a relatively high weight due to their numerous components, which will bring a heavy burden to the users wearing the head-mounted display device. At the same time, as Figure 2As shown, the rear fixing fitting 15 and the front fixing fitting 16 of the VR head-mounted device adopted in the related art are both arranged in the front area and the rear area of the user's head. In this way, when the user wears the head-mounted display device, the front area and the rear area of the head will bear more pressure, and the stability of the user when wearing the head-mounted display device is also often poor.

[0058] In view of the above phenomenon, the present application proposes a head-mounted display device including: a head-mounted display main body; a frame connected to the head-mounted display main body, the frame being used to assist the wearer in wearing the head-mounted display main body on the head; a micro airbag connected to the inner side wall of the frame; an air charging and discharging unit connected to the micro airbag; and a controller electrically connected to the air charging and discharging unit for controlling the air charging and discharging unit to perform an air charging operation or an air discharging operation according to the head wearing state of the wearer.

[0059] That is, the present application detects the wearer wearing the head-mounted display device through the control inside the head-mounted display device. Thus, when it is detected that the head wearing state of the wearer is in a preset standard wearing state and the micro airbag connected to the inner side wall of the frame is normally connected to the air charging and discharging unit, the air charging and discharging unit is controlled to perform an air charging operation to open the micro airbag, so that the micro airbag connected to the inner side wall of the frame can effectively support the side of the wearer's head, thereby solving the technical problem in the related art that when the user wears the head-mounted display device, the head-mounted display device will generate more pressure on the front area and the rear area of the user's head, and further achieving the effect of reducing the pressure on the head of the user when wearing the head-mounted display device to improve the stability of the user when wearing the head-mounted display device.

[0060] Based on the overall concept of the head-mounted display device of the present application, various embodiments of the head-mounted display device of the present application are further proposed.

[0061] Please refer to Figure 2 , Figure 2 , which is a detailed structural schematic diagram of an embodiment of the head-mounted display device of the present application. In this embodiment, the head-mounted display device includes:

[0062] A head-mounted display main body;

[0063] A frame connected to the head-mounted display main body, the frame being used to assist the wearer in wearing the head-mounted display main body on the head;

[0064] A micro airbag connected to the inner side wall of the frame;

[0065] An air charging and discharging unit connected to the micro airbag;

[0066] A controller electrically connected to the air charging and discharging unit for controlling the air charging and discharging unit to perform an air charging operation or an air discharging operation according to the head wearing state of the wearer.

[0067] Specifically, as shown in Figure 2 , the head-mounted display device includes: a head-mounted display main body 1, a frame 2, a micro airbag 3, an air charging and discharging unit 4, and a controller (not shown in the figure). A display device 5 is configured on the head-mounted display main body 1. The frame 2 is connected to the head-mounted display main body 1. The frame 2 is used to assist the wearer in fixing the head-mounted display main body 1 on the head and enabling the wearer to adjust the position of the display device 5 in the head-mounted display main body 1 through the frame. The micro airbag 3 is disposed on the inner sidewall of the frame 2 for supporting the side area of the wearer's head. The air charging and discharging unit 4 is connected to the micro airbag 3 for inflating or deflating the micro airbag 3. The controller is electrically connected to the air charging and discharging unit 4 for controlling the air charging and discharging unit 4 to perform an air inflation operation or an air deflation operation on the micro airbag 3 according to the head wearing state of the wearer.

[0068] It should be noted that, please refer to Figure 4 , Figure 4 , which is a schematic structural diagram of the micro airbag involved in an embodiment of the head-mounted display device of the present application. As shown in Figure 4 , the micro airbag 3 includes: an airbag body (not labeled in the figure), an airbag inflation port 6, and a first metal pin point 7. Similarly, please refer to Figure 5 , Figure 5 , which is a schematic structural diagram of the air charging and discharging unit involved in an embodiment of the head-mounted display device of the present application. As shown in Figure 5 , the air charging and discharging unit 4 includes: a PCB board 17. An air charging and discharging device 8 (which can be a micro piston) and a second metal pin point 9 are disposed on the PCB board 17. By connecting the airbag inflation port 6 of the micro airbag 3 to the air charging and discharging device 8 and connecting the first metal pin point 7 in the micro airbag 3 to the second metal pin point 9 in the air charging and discharging unit 4, the micro airbag 3 is connected to the air charging and discharging unit 4 and data transmission is achieved;

[0069] In addition, in this embodiment and another embodiment, an airbag locking button 10 is further configured on the frame 2. When the micro airbag 3 is connected to the air charging and discharging unit 4, the micro airbag 3 can be fixed to the air charging and discharging unit 4 through the airbag locking button 10, so as to ensure that the micro airbag 3 will not be separated from the air charging and discharging unit during the inflation process.

[0070] Furthermore, in a feasible embodiment, an airbag fixing buckle is provided on the inner sidewall of the frame, and a mating hole is provided on the micro airbag, and the mating hole is in snap-fit with the airbag fixing buckle.

[0071] Specifically, as shown in Figure 2As shown in the figure, an airbag fixing buckle 11 is provided on the inner side wall of the frame 2. An airbag fixing buckle mating hole 12 is provided inside the micro airbag 3. The micro airbag 3 can be snap-fitted with the airbag fixing buckle 11 through the airbag fixing buckle mating hole 12, so as to fix the micro airbag 3 on the inner side wall of the frame 2.

[0072] In addition, in this embodiment and another embodiment, a fixing hole 13 is further provided on the inner side wall of the frame 2, and a side fixing protrusion 14 is further provided inside the micro airbag 3. The micro airbag 3 can be snap-fitted with the fixing hole 13 through the side fixing protrusion 14, so as to fix the micro airbag 3 on the inner side wall of the frame 2.

[0073] In this way, in this application, the wearer wearing the head-mounted display device is detected through the control inside the head-mounted display device. Thus, when it is detected that the head wearing state of the wearer is in a preset standard wearing state and the micro airbag connected to the inner side wall of the frame is normally connected to the air charging and discharging unit, the air charging and discharging unit is controlled to perform an inflation operation to open the micro airbag, so that the micro airbag connected to the inner side wall of the frame can effectively support the side of the wearer's head. Thereby, the technical problem in the related art that when the user wears the head-mounted display device, the head-mounted display device generates more pressure on the front area and the rear area of the user's head is solved. Furthermore, the pressure on the head of the user when wearing the head-mounted display device is reduced, so as to improve the stability of the user when wearing the head-mounted display device.

[0074] Based on the above head-mounted display device and the overall concept of the head-mounted display device of this application, various embodiments of the airbag control method of this application are further proposed.

[0075] Please refer to Figure 3 , Figure 3 which is a schematic flowchart of the first embodiment of the airbag control method of this application.

[0076] It should be understood that although the logical order is shown in the flowchart, in some cases, the airbag control method of this application can of course be executed in a different order from the steps shown or described here.

[0077] In this embodiment, the airbag control method of this application is applied to the above head-mounted display device. As Figure 3 shown, the airbag control method of this application may include the steps:

[0078] Step S10: Detect the head wearing state of the wearer wearing the head-mounted display device;

[0079] Step S20: If the head wearing state is in a preset standard wearing state, then detect the working state corresponding to the air charging and discharging unit;

[0080] Step S30: When the working state is the connected state, control the air charging and discharging unit to perform an air charging operation until the real-time airbag pressure value of the micro airbag reaches the first target pressure value;

[0081] It should be noted that the head wearing state refers to the state of the wearer's own head when wearing the head-mounted display device, that is, this wearing state can indicate whether the wearer wears the head-mounted display device in a standard posture. It can be understood that this head wearing state is specifically divided into a standard wearing state (that is, the distance between the wearer's eyes and the display screen of the head-mounted display device is a preset target value) and a non-standard wearing state (that is, the distance between the wearer's eyes and the display screen of the head-mounted display device is not the target value) based on whether the wearer wears the head-mounted display device in a standard posture;

[0082] In addition, this working state indicates whether the communication connection state between the air charging and discharging unit and the micro airbag is normal, that is, this working state can be specifically divided into a connected state and a disconnected state based on whether the air charging and discharging unit can receive the data information sent by the micro airbag;

[0083] In this embodiment, when the wearer wears the head-mounted display device, the head-mounted display device first detects the wearer and generates a first detection result. Then, the head-mounted display device determines whether the corresponding head wearing state of the wearer is the preset standard wearing state or the non-standard wearing state based on this first detection result. After that, when the head-mounted display device determines that this wearing state is the preset standard wearing state, it further detects the air charging and discharging unit configured in itself and generates a second detection result. The head-mounted display device determines whether the working state between the air charging and discharging unit and the micro airbag is the connected state based on this second detection result. Finally, when the head-mounted display device determines that the state between the air charging and discharging unit and the micro airbag is the connected state, it controls the air charging and discharging unit to make the air charging and discharging device configured in the air charging and discharging unit perform an air charging operation, so as to inflate the airbag body in the micro airbag, so that the real-time airbag pressure value in the micro airbag reaches the first target pressure value.

[0084] Exemplarily, for example, when the wearer wears the head-mounted display device, the head-mounted display device first detects the wearer through the eye-tracking device configured therein to generate a first detection result, and uploads the first detection result to the head-mounted display device. Then, the head-mounted display device determines whether the wearing state corresponding to the wearer is the preset standard wearing state or the non-standard wearing state based on the preset eye-tracking algorithm and the first detection result. After that, when the head-mounted display device determines that the wearing state is the preset standard wearing state, it further detects the air charging and discharging unit configured therein and connected to the micro airbag to generate a second detection result, and then determines whether the air charging and discharging unit can communicate with the micro airbag based on the second detection result, and further determines whether the working state between the air charging and discharging unit and the micro airbag is the connected state. Finally, when the head-mounted display device determines that the working state is the connected state, it determines that the air charging and discharging unit and the micro airbag can perform normal communication and data transmission. Then, the head-mounted display device controls the operation of the micro piston configured in the air charging and discharging unit, so that the micro piston conveys air to the airbag body through the airbag inflation port in the micro airbag, and further makes the airbag body expand, so that the real-time airbag pressure value contained in the airbag body reaches the preset first target pressure value.

[0085] It can be understood that the first target pressure value is the pressure value generated by the air contained in the airbag body when the micro airbag supports the side of the wearer's head to make the wearer in the best comfort state. The first target pressure value can be obtained by technicians through experiments on the head model in the laboratory environment;

[0086] In addition, in this embodiment and another embodiment, technicians can also store multiple pressure values in the storage device of the head-mounted display device, so that the wearer can select the pressure value that makes himself feel comfortable from the multiple pressure values as the first target pressure value based on the size of his own head;

[0087] In addition, in this embodiment and another embodiment, before the wearer wears the head-mounted display device, the head-mounted display device can also obtain the real-time head size corresponding to the wearer. At the same time, the head-mounted display device reads its own storage device to obtain a pressure value database containing multiple standard head sizes and the standard pressure values corresponding to the multiple standard head sizes respectively. After that, the head-mounted display device filters the pressure value database based on the real-time head size, compares the real-time head size with the multiple standard head sizes respectively, and thus determines the first target pressure value corresponding to the wearer from the multiple standard pressure values.

[0088] Thus, the present application solves the technical problem in the related art that when a user wears a virtual display device, the virtual display device generates relatively more pressure on the front area and the rear area of the user's head. That is, when it is detected that the user correctly wears the head-mounted display device and the micro airbag provided on the side of the head-mounted display device is normally connected to the air charging and discharging unit, the air charging and discharging unit is controlled to inflate the micro airbag to deploy the micro airbag, so that when the user wears the head-mounted display device, the head-mounted display device can automatically turn on the micro airbag provided on the side, thereby reducing the pressure borne by the front and rear of the user's head and improving the stability when the user wears the head-mounted display device.

[0089] Further, in a feasible embodiment, the above step S10 may specifically include:

[0090] Step S101: Detect the pose information of the wearer's head in the head cavity of the head-mounted display device;

[0091] Step S102: If the pose information is a preset standard pose, determine that the head wearing state is in a preset standard wearing state;

[0092] Step S103: If the pose information is not a preset standard pose, determine that the head wearing state is not in a preset standard wearing state;

[0093] In this embodiment, when the wearer wears the head-mounted display device, the head-mounted display device calls the image acquisition device configured by itself to identify the wearer to capture a target image including the wearer, and the image acquisition device then identifies the target image to determine the pose information of the wearer's head in the head cavity of the head-mounted display device through the target image. After that, if the head-mounted display device determines that the pose information is a preset standard pose, it determines that the head wearing state corresponding to the wearer is a preset standard wearing state, and if the head-mounted display device determines that the pose information is not a preset standard pose, it determines that the head wearing state corresponding to the wearer is not in a preset standard wearing state. Thus, when the user wears the head-mounted display device, the head-mounted display device can identify the user's wearing posture and determine whether the user's wearing posture is correct, and further ensure that when the user does not wear the head-mounted display device in the correct posture, the inflation of the micro airbag is stopped to avoid causing an additional burden on other areas of the wearer's head by the micro airbag.

[0094] Further, in a feasible embodiment, the above step S101 may specifically include:

[0095] Step S1011: Detect the real-time distance value between the wearer's head in the head cavity and a preset calibration component;

[0096] Step S1012: Determine the pose information of the wearer's head based on the real-time distance value;

[0097] In this embodiment, when the wearer wears the head-mounted display device, the head-mounted display device calls the image acquisition device configured therein to identify the wearer, so as to capture a target image including the wearer. The image acquisition device then identifies the target image to determine the real-time distance value between the wearer's head and the display device in the head cavity through the target image. After that, the head-mounted display device reads the storage device configured therein to obtain the distance threshold preset by the technician, and compares the real-time distance value with the distance threshold to obtain a first comparison result. Then, when the head-mounted display device determines that the first comparison result is that the real-time distance value is less than or equal to the distance threshold, it determines that the pose information of the wearer's head is in the preset standard pose. If the head-mounted display device determines that the first comparison result is that the real-time distance value is greater than the distance threshold, it determines that the pose information of the wearer's head is not in the preset standard pose.

[0098] Exemplarily, for example, when the wearer wears the head-mounted display device, the head-mounted display device calls the camera configured therein to identify the wearer, so as to capture a target image including the wearer. The head-mounted display device then extracts the image features of the target image and determines the real-time distance value between the wearer's eyes and the display device 5 configured in the head-mounted display device itself based on the image features. After that, the head-mounted display device reads the storage device to obtain the distance threshold corresponding to the head-mounted display device preset by the technician, and compares the real-time distance value with the distance threshold to obtain a first comparison result. Then, if the head-mounted display device determines that the first comparison result is that the real-time distance value is less than or equal to the distance threshold, it determines that the user wears the head-mounted display device in the correct posture and determines that the pose information corresponding to the wearer's head is the preset standard pose. If the head-mounted display device determines that the first comparison result is that the real-time distance value is greater than the distance threshold, it determines that the user does not wear the head-mounted display device in the correct posture and determines that the pose information corresponding to the wearer's head is not the preset standard pose.

[0099] It should be noted that the distance threshold is the distance value between the display device in the head-mounted display device and the user's eyes when the user wears the head-mounted display device in the correct posture. It can be understood that the distance threshold can be obtained by the technician through experiments on the head model in the laboratory. The present application does not limit the specific value of the distance threshold. In addition, the preset calibration component can be any other component in the head-mounted display device in addition to the display device 5. The present application does not limit this.

[0100] In addition, in this embodiment and another embodiment, an infrared sensor may also be configured on the frame of the head-mounted display device. When the user wears the head-mounted display device, the head-mounted display device then calls the infrared sensor to detect the user to generate a third detection result, and determines the real-time distance value between the user's eyes and the display device based on the third detection result. The head-mounted display device then determines the pose information of the user's head in the head cavity based on the real-time distance value. Similarly, in addition to detecting through the infrared sensor, a cap sensor may also be configured on the frame of the head-mounted display device. Since when the user wears the head-mounted display device in the correct posture, their skin will inevitably come into contact with the cap sensor, causing the cap sensor to generate specific current information. Therefore, when the user wears the head-mounted display device, the head-mounted display device can also call the cap sensor to detect the user, and determine the pose information of the user's head in the head cavity based on whether the cap sensor generates specific current. Specifically, when the user wears the head-mounted display device, the head-mounted display device detects the cap sensor to obtain a fourth detection result. After that, if the head-mounted display device determines that the fourth detection result is that the current generated by the cap sensor is consistent with the preset target current, it determines that the pose information of the user's head in the head cavity is the preset standard pose. In this way, when the user wears the head-mounted display device, the head-mounted display device can further improve the accuracy of detecting the user, so as to better control the timing of activating the micro airbag.

[0101] Further, in a feasible embodiment, the step of "detecting the working state corresponding to the air charging and discharging unit" in step S20 may specifically include:

[0102] Step S201: Detect the information receiving state corresponding to the air charging and discharging unit;

[0103] Step S202: If the information receiving state is the target receiving state, determine that the working state corresponding to the air charging and discharging unit is the connected state;

[0104] It should be noted that the information receiving state may specifically include a target receiving state and an abnormal receiving state. Among them, the target receiving state indicates that the air charging and discharging unit can normally receive the data signal sent by the micro airbag through the metal pin points configured on itself. Similarly, the abnormal receiving state means that the air charging and discharging unit cannot receive the data information sent by the micro airbag through the metal pin points configured on itself.

[0105] In this embodiment, after the head-mounted display device determines that the head-wearing state corresponding to the wearer is the preset standard wearing state, it continues to detect its configured air charging and discharging unit and generates a second detection result. Based on this second detection result, the head-mounted display device determines whether the information receiving state corresponding to the air charging and discharging unit is the target receiving state or the abnormal receiving state. Then, the head-mounted display device determines whether the working state between the air charging and discharging unit and the micro airbag is the connected state or the disconnected state based on the information receiving state corresponding to the air charging and discharging unit.

[0106] Exemplarily, for example, after the head-mounted display device determines that the head-wearing state corresponding to the wearer is the preset standard wearing state, it continues to detect the second metal pin point in its configured air charging and discharging unit. Then, based on whether the second metal pin point can receive the data signal sent by the micro airbag through its first metal pin point, it determines whether the information receiving state corresponding to the air charging and discharging unit is the target receiving state or the abnormal receiving state. After that, the head-mounted display device determines whether normal data signal transmission can be performed between the air charging and discharging unit and the micro airbag based on the information receiving state corresponding to the air charging and discharging unit, and further determines whether the overall working state between the air charging and discharging unit and the micro airbag is the connected state or the disconnected state. In this way, the head-mounted display device can accurately detect the connection state between the air charging and discharging unit and the micro airbag, and then determine whether to inflate the micro airbag based on this connection state.

[0107] Further, a first information transmission component is configured in the micro airbag, and a second information transmission component is configured in the air charging and discharging unit;

[0108] In a feasible embodiment, the above step S201 may specifically include:

[0109] Step S2011: Detect whether the second information transmission component can receive the data signal transmitted by the first information transmission component;

[0110] Step S2012: If the second information transmission component can receive the data signal, determine that the information receiving state corresponding to the air charging and discharging unit is the target receiving state;

[0111] It should be noted that the first information transmission component is the first metal pin point configured in the micro airbag. Similarly, the second information transmission component is the second metal pin point configured in the air charging and discharging unit. It can be understood that only when the first metal pin point of the micro airbag contacts the second metal pin point of the air charging and discharging unit and the airbag inflation port is connected to the air charging and discharging device, the air charging and discharging unit and the micro airbag are in the connected state.

[0112] In this embodiment, when the head-mounted display device detects the inflation / deflation unit, it first detects the second information transmission component in the inflation / deflation unit to determine whether the second information transmission component can receive the data signal sent by the micro airbag through the first information transmission component. Then, if the head-mounted display device determines that the second information transmission component can receive the data signal sent through the first information transmission component, it determines that the communication connection between the micro airbag and the inflation / deflation unit is normal, and the head-mounted display device further determines that the information reception state corresponding to the inflation / deflation unit is the target reception state.

[0113] Exemplarily, for example, the micro airbag can regularly send a specific data signal to the inflation / deflation unit through the first metal pin point configured on itself. The specific data signal can enter the inflation / deflation unit through the second metal pin point connected to the first metal pin point. When the head-mounted display device detects the inflation / deflation unit, it can directly detect the second metal pin point to determine whether the second metal pin point can receive the specific data signal sent by the micro airbag. Then, if the head-mounted display device determines that the second metal pin point can receive the specific data signal, it determines that the communication connection between the inflation / deflation unit and the micro airbag is normal, and the head-mounted display device further determines that the information reception state corresponding to the inflation / deflation unit is the target reception state. In this way, the head-mounted display device can accurately detect the communication connection state between the inflation / deflation unit and the micro airbag, and then determine whether to control the inflation / deflation unit to inflate the micro airbag based on the communication connection state.

[0114] Based on the first embodiment of the airbag control method of the present application above, a second embodiment of the airbag control method of the present application is proposed here.

[0115] Further, in a feasible embodiment, after the above step S103, the airbag control method of the present application may further include the following steps:

[0116] Step A10: Detect the real-time airbag pressure value of the micro airbag, and compare the real-time airbag pressure value with the airbag pressure threshold to obtain a comparison result;

[0117] Step A20: When the comparison result is that the real-time airbag pressure value is greater than or equal to the airbag pressure threshold, control the inflation / deflation unit to perform a deflation operation until the real-time airbag pressure value reaches a second target pressure value, where the second target pressure value is less than the first target pressure value;

[0118] It should be noted that the airbag pressure threshold is a pressure threshold preset by those skilled in the art for determining whether to deflate the micro airbag. It can be understood that the specific value of the airbag pressure threshold can be set by those skilled in the art based on factors such as the material of the airbag body, and the present application does not limit this.

[0119] In addition, the second target pressure value is the pressure value generated by the air contained in the airbag body when the micro airbag is fully contracted. It can be understood that the second target pressure value should be less than the above-mentioned first target pressure value, and the specific value of the second target pressure value is not limited in this application.

[0120] In this embodiment, when the head-mounted display device determines that the head wearing state of the wearer is not in the preset standard wearing state, it calls the detection device configured in itself to detect the air charging and discharging unit, so as to determine the real-time airbag pressure value corresponding to the air contained in the micro airbag through the air charging and discharging unit. At the same time, the head-mounted display device reads the above-mentioned storage device to obtain the airbag pressure threshold preset by the technician, and compares the real-time airbag pressure value with the airbag pressure threshold to obtain a second comparison result. Finally, if the head-mounted display device determines that the second comparison result is that the real-time airbag pressure value is greater than or equal to the airbag pressure threshold, it controls the air charging and discharging device in the air charging and discharging unit to make the air charging and discharging unit perform a deflation operation to discharge the air in the micro airbag, so that the real-time airbag pressure value in the micro airbag reaches the second target pressure value.

[0121] Exemplarily, for example, when the head-mounted display device determines that the head wearing state of the wearer is not in the preset standard wearing state, it calls a pressure sensor to detect the micro piston in the air charging and discharging unit, so as to determine the pressure received by the micro piston from the airbag inflation port, and determines the pressure received by the micro piston from the airbag inflation port as the real-time airbag pressure value corresponding to the air in the airbag body. At the same time, the head-mounted display device reads the storage device to obtain the pressure threshold preset by the technician, and compares the real-time airbag pressure value with the pressure threshold to obtain a second comparison result. Finally, when the head-mounted display device determines that the second comparison result is that the gas pressure value is greater than or equal to the pressure threshold, the head-mounted display device controls the micro piston to discharge the air contained in the airbag body through the micro piston, so that the real-time airbag pressure value in the micro airbag reaches the second target pressure value, so as to make the micro airbag complete contraction. In this way, the head-mounted display device can timely close the micro airbag when the user does not wear the head-mounted display device, thereby avoiding the micro airbag being in a high-pressure working state for a long time and further improving the service life of the micro airbag.

[0122] Based on the first embodiment and / or the second embodiment of the airbag control method of this application, a third embodiment of the airbag control method of this application is proposed here.

[0123] Further, in a feasible embodiment, after the above step S2011, the airbag control method of this application may further include the following steps:

[0124] Step B10: If the second information transmission component fails to receive the data signal, determine that the information reception status corresponding to the air charging and discharging unit is an abnormal reception status;

[0125] Step B20: Generate a prompt message indicating an abnormal connection of the micro airbag based on the abnormal reception status, and output the prompt message;

[0126] In this embodiment, when the head-mounted display device detects the air charging and discharging unit, if it is determined that the second information transmission component in the air charging and discharging unit fails to receive the data signal sent by the micro airbag through the first information transmission component, it is determined that the information reception status corresponding to the air charging and discharging unit is an abnormal reception status. Then, the head-mounted display device generates a prompt message based on this abnormal reception status and outputs the prompt message to the display module configured in itself, so as to externally display the prompt message to the user through the display module, so that the wearer can fix the micro airbag based on the prompt message.

[0127] Exemplarily, for example, during the process of the head-mounted display device detecting the air charging and discharging unit, if it is determined that the second metal pin point in the air charging and discharging unit fails to receive the specific data signal sent by the micro airbag through the first metal pin point, the head-mounted display device determines that the communication connection between the air charging and discharging unit and the micro airbag is abnormal, that is, the connection between the air charging and discharging unit and the micro airbag may be loose. The head-mounted display device further determines that the information reception status corresponding to the air charging and discharging unit is an abnormal reception status. Then, the head-mounted display device generates a prompt message "Please fix the micro airbag on the side of the device", and generates a visual prompt interface based on this prompt message, and then inputs the prompt interface into the display device configured in itself, so as to externally display the prompt interface to the user through the display device, so that the wearer can manually fix the connection point between the micro airbag and the air charging and discharging unit based on the prompt interface. In this way, when the air charging and discharging unit cannot inflate the micro airbag due to loose connection, the head-mounted display device can timely generate a reminder message to enable the user to fix the micro airbag, so as to ensure the normal activation of the micro airbag.

[0128] Further, based on the above embodiments of the airbag activation method of the head-mounted display device of the present application, a preferred embodiment of the airbag control method of the present application is proposed here.

[0129] Further, please refer to Figure 6 , Figure 6 which is a schematic flowchart of a preferred embodiment of the airbag control method of the present application, Figure 6As shown, in this embodiment, when the wearer turns on the head-mounted display device and wears it, the head-mounted display device calls the infrared sensor, or the capping sensor, or the eye tracking device configured therein to detect the wearer to generate a first detection result. Then, the head-mounted display device determines whether the head wearing state of the wearer is a preset standard wearing state or a non-standard wearing state based on the first detection result. After that, when the head-mounted display device determines that the head wearing state of the wearer is the preset standard wearing state, it further detects the charging and discharging unit configured therein to generate a second detection result, and determines whether the working state of the micro airbag configured therein is a connected state based on the second detection result. Finally, when the head-mounted display device determines that the working state of the micro airbag is the connected state, it controls the charging and discharging unit to perform an inflation operation so that the real-time airbag pressure value in the micro airbag reaches a preset first target pressure value, thereby fully deploying the micro airbag;

[0130] In addition, after the head-mounted display device generates the first detection result, if the head-mounted display device determines that the head wearing state of the wearer is a non-standard wearing state based on the first detection result, it further detects the charging and discharging unit to determine the real-time airbag pressure value corresponding to the micro airbag. Then, the head-mounted display device determines whether the real-time airbag pressure value reaches a preset pressure threshold, and when it determines that the real-time airbag pressure value reaches the pressure threshold, it controls the charging and discharging unit to perform a deflation operation so that the real-time airbag pressure value in the micro airbag reaches a preset second target pressure value that is less than the first target pressure value, thereby fully closing the micro airbag.
