Description of the main elements
The following detailed description will further illustrate the present application in conjunction with the above-described figures.
Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
In the following, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature.
In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "connected," and "connected" are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; the specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
Virtual Reality (VR), augmented Reality (AR), and Mixed Reality (MR) technologies are emerging multimedia technologies in recent years. Virtual reality technology is a computer simulation system that can create and experience a virtual world. The augmented reality technology is a technology that can superimpose and interact virtual reality and a real world. The mixed reality technology is characterized in that virtual scene information is introduced into a real environment, and an interactive feedback information loop is constructed among the real world, the virtual world and a user so as to enhance the reality sense of user experience, and the mixed reality technology has the characteristics of reality, real-time interactivity, imagination and the like.
In VR, AR or MR scenarios, a user typically wears a Head Mounted Display (HMD) consisting of an integrated graphics system, optical system and gesture tracking system, which may provide an interactive immersive experience for the user of the device. The head-mounted display apparatus is in direct contact with the face and the head of a person when in use, and therefore it is necessary to provide a support structure at the contact position to improve wearing comfort.
Referring now to fig. 1A, 1B and 1C, the cushioning material used in the support structures 100a,200a of conventional headgear (e.g., mask 100, headgear 200) is typically a foam or strap that conforms to the contours of the user's head and face by deforming itself (e.g., see fig. 2). Although the foam or the strap can fit the outline of the head and face of the user in most cases, some disadvantages may still exist, for example, 1, in the wearing state, the contact position of the foam or the strap and the head and face is fixed, and the force-bearing position is easy to be uncomfortable when the user wears the head and face; 2. the supporting structure has larger volume and is not beneficial to the storage of products; 3. the air in the fitting area is not circulated, and the wearing comfort is poor for a long time.
Therefore, this application embodiment provides a head-mounted device, through set up multilayer gasbag mechanism on support piece, every layer gasbag mechanism corresponds the gasbag unit that different regions set up correspondences to the gassing of filling of control gasbag unit, so that gasbag unit and user's head facial profile laminating, and then effectively improve controllability and comfortable wearability.
Specifically, please refer to fig. 3, which illustrates a headset 300 according to an embodiment of the present disclosure. The head mounted device 300 may include a display unit (not shown). The display unit is used for displaying information. Wherein, when the head-mounted device 300 is worn on the head of the user, the user can see the image presented by the display unit of the head-mounted device 300. As such, the head mounted device 300 may constitute a head mounted display device (HMD), such as smart glasses, a smart mask, a smart helmet, or the like. Of course, it is understood that in other embodiments, the head-mounted device 300 may not be provided with a display unit. As such, the head mounted device 300 constitutes a head mounted device without a display function. In the following embodiments, the head mount device 300 is taken as an example of a head mount display device (HMD).
By way of example, the head-mounted device 300 may be an Augmented Reality (AR) device. This allows the virtual image to be displayed to the user while the user is viewing the real world scene. The user may also interact with the virtual image to achieve an augmented reality effect. It is understood that the embodiment of the present application describes the head-mounted device 300 as an Augmented Reality (AR) device, but the embodiment of the present application is not limited to the Augmented Reality (AR) device, and may also be other head-mounted display devices, for example, a device for implementing a Virtual Reality (VR) effect or a device for implementing a Mixed Reality (MR) effect.
It is understood that, as shown in fig. 3, the head-mounted device 300 includes at least a support member 31, an air bag mechanism 33, and a control unit 35 (see fig. 5). Of course, the head-mounted device 300 may also include other components, such as a power supply, a processor, an interface, etc., which are not described in detail herein.
In one embodiment, the head-mounted device 300 is a mask having a shape and contour corresponding to the face of the user. The support 31 may constitute a mask body. In the embodiment, the supporting member 31 is substantially annular, and an opening 310 is formed at a middle position thereof. When the head mounted device 300 includes a display unit, the display unit may be disposed corresponding to the opening 310 such that when the head mounted device 300 is worn on the head of the user, the user can see contents displayed by the display unit through the opening 310.
It is understood that in other embodiments, the headgear 300 is not limited to a mask, nor is the support 31 limited to a mask body. For example, the support 31 may also be a base (e.g., a smart helmet base), so that the head-mounted device 300 constitutes a wearable device such as a smart helmet. In the following embodiments, for convenience of description, the head-mounted device 300 is exemplified as the mask shown in fig. 3.
The support 31 includes a first surface 311 and a second surface 312. The first surface 311 is opposite to the second surface 312. In the present embodiment, the airbag mechanism 33 is integrally disposed on the first surface 311 of the support member 31. In the present embodiment, the airbag mechanism 33 includes a plurality of airbag units 331 (e.g., 7 as shown in fig. 3). The plurality of air bag units 331 are sequentially arranged on the periphery of the first surface 311 of the support member 31 and are enclosed into a ring shape, so that the middle part of the first surface 311 of the support member 31 is exposed. As such, when the head-mounted device 300 is worn on the head of the user, the plurality of airbag units 331 may be disposed around the eyes of the user and conform to the contours around the eyes of the user without the middle portion of the support 31 obstructing the vision of the user.
It is to be understood that, in the embodiment of the present application, the manner in which the airbag mechanism 33 is disposed on the first surface 311 is not limited. For example, the airbag mechanism 33 may be directly mounted to the first surface 311 of the support member 31 by means of an adhesive. Alternatively, the air bag mechanism 33 may be mounted to the first surface 311 of the support 31 by a snap-fit or the like connection.
It is understood that, in the embodiment of the present application, the shape, size, thickness, and the like of each of the plurality of airbag units 331 may be adapted to different attachment regions, and are not particularly limited herein. In one embodiment, a plurality of air bag units 331 may be configured to be symmetrically disposed. For example, a plurality of air bag units 331 may be disposed symmetrically about both sides of a human eye, and a smaller air bag unit 331 may be disposed at a position corresponding to the bridge of the nose in the middle, where the thickness of the air bag unit 331 is also smaller than that of the air bag units 331 at other positions. For example, the air bag unit 331 having a large area and a large thickness may be provided at positions corresponding to the upper and lower sides and the left and right sides of the human eyes, so that the user can fit the face of the user over a large area, thereby improving comfort.
It will be appreciated that referring again to fig. 3, in one embodiment, each air bag unit 331 includes two support air bags 3311. The two support bladders 3311 are disposed in a direction parallel to the first surface 311. Of course, in the embodiment of the present application, the number of the supporting airbags 3311 in each airbag unit 331 is not particularly limited, and may be adjusted according to the size corresponding to different attachment positions or regions. For example, the number of the supporting airbags 3311 in each airbag unit 331 may also be one, three, or more.
It is understood that, in other embodiments, the number and the position of the air bag units 331 are not limited to the above, and can be adjusted according to specific requirements. For example, in one embodiment, the bladder unit 331 may be configured to correspond to a critical support location of the headgear 300. While for non-critical support positions of the head-mounted device 300, the air cell 331 may be omitted or the number thereof may be adjusted accordingly.
It is to be understood that, in the present embodiment, the head mount 300 is provided with the multilayer airbag mechanism 33 in the thickness direction of the airbag unit 331. For example, referring to fig. 4A, the head-mounted device 300 is provided with three layers of airbag mechanisms 33 along a first direction (i.e., a thickness direction of the airbag unit 331), and the airbag units 331 in the three layers of airbag mechanisms 33 may be sequentially stacked along a direction away from the first surface 311. Wherein the first direction is perpendicular to the direction parallel to the first surface 311 (i.e., the second direction).
As another example, referring to fig. 4B, the head-mounted device 300 is provided with a three-layer airbag mechanism 33 along the first direction. The air bag units 331 in the three-layer air bag mechanism 33 may be alternately stacked (i.e., laminated) in order in a direction away from the first surface 311. Of course, in the embodiment of the present application, the arrangement manner of the multi-layer airbag mechanism 33 is not limited to the above two manners, and may be other manners, which are not specifically limited herein.
Referring to fig. 4A and 4B, in the embodiment of the present application, only the three-layer airbag mechanism 33 is shown in the thickness direction of the head-mounted apparatus 300. It should be understood that the number of layers of the multilayer airbag mechanism 33 is not particularly limited in the present embodiment, and may be, for example, one layer, two layers, or multiple layers. It is to be understood that, for the convenience of description, the following embodiments are described only by way of example of the head-mounted device 300 being provided with a layer of the airbag mechanism 33 (see, for example, fig. 3).
It is to be understood that when the head mount 300 is provided with the multiple layers of the airbag mechanisms 33, the number of the airbag units 331 in each layer and different layers of the airbag mechanisms 33 or the number of the supporting airbags 3311 in the airbag units 331 is not limited either. For example, the number of the airbag units 331 provided in the airbag mechanisms 33 of different layers may be the same or different. For another example, the number of supporting airbags 3311 in the airbag units 331 provided in the same layer may be the same or different.
Referring to fig. 5, in the embodiment of the present application, the control unit 35 includes a controller 351, an inflation/deflation mechanism 352 and a connecting member 353. Wherein the controller 351 is connected to one or more support bladders 3311 by a connection 353 and to the inflation and deflation mechanism 352 by the connection 353. In one embodiment, the connector 353 is an air tube.
Referring also to fig. 6, controller 351 includes an inflation controller 3511 and a deflation controller 3512. Wherein inflation controller 3511 and deflation controller 3512 are each connected to one or more support bladders 3311 (one shown) by connectors 353. The other end of the bleed controller 3512 is also connected to atmosphere.
In one embodiment, the inflation/deflation mechanism 352 comprises an air pump 3521 and an air storage balloon 3522. Wherein, the gas storage balloon 3522 may be connected to the gas pump 3521 through a connection member 353, and store a certain gas and maintain a certain pressure under the control of the gas pump 3521. The gas storage bladders 3522 may also be connected to the inflation controller 3511 through connectors 353 for inflation of the respective support bladders 3311 under the control of the inflation controller 3511.
It is to be understood that the inflation and deflation processes and principles of the support airbag 3311 are described in detail below.
First, the gas storage balloon 3522 stores corresponding gas and maintains a certain pressure by the gas pump 3521. The inflation controller 3511 is connected to the gas storage bladder 3522 and the corresponding support bladder 3311, respectively, by a connector 353, such as a gas tube. Next, the inflation controller 3511 turns on or off (e.g., by opening or closing an inflation valve) to connect or disconnect the corresponding support bladder 3311 (e.g., the support bladder 3311 to be inflated) to the gas storage bladder 3522. In the connected state, the gas in the gas storage bladder 3522 flows toward the support bladder 3311 to inflate the support bladder 3311, and the support bladder 3311 can provide a certain support function while maintaining a certain pressure. In the disconnected state, the gas inside the gas storage bladder 3522 cannot flow into the corresponding support bladder 3311.
It is understood that the other end of the support bag 3311 is connected to the atmosphere through the gas release controller 3512. In this manner, the bleed controller 3512 can communicate or disconnect the respective support bladder 3311 (e.g., the support bladder 3311 that needs to be deflated) from the atmosphere by switching (e.g., by opening or closing a bleed valve). Wherein, in the connected state, the gas in the support airbag 3311 that needs to be deflated flows out under the action of an external force or a pressure difference, thus no longer providing an effective support. In the off state, the supporting airbag 3311 stores a corresponding gas therein and has a certain pressure, thereby providing a certain supporting function.
It will be appreciated that in the present embodiment, each air bag unit 331 is connected to a separate controller 351, i.e., one or more (e.g., two) support air bags 3311 in one air bag unit 331 correspond to one controller 351. Therefore, each air bag unit 331 can be independently controlled, so as to realize the charging and discharging air-conditioning of the air bag unit 331 in different areas, so as to realize the wide-range adjustment of the shape of the head-mounted device 300, and the head-mounted device 300 can meet the requirements of different facial people.
It is understood that, when the head-mounted device 300 is provided with a plurality of layers of the airbag units 331 along the first direction, the supporting airbags 3311 in the airbag units 331 of the same layer may each correspond to one controller 351, and thus, one controller 351 may realize inflation and deflation control of the supporting airbags 3311 in the airbag units 331 of the same layer.
It is understood that, in the embodiment of the present application, when the head mount 300 is worn for a long time, by adjusting the internal pressure of the airbag unit 331 in different areas, the change in the position of the face support can be achieved, and discomfort caused by pressing the same position for a long time can be alleviated. Meanwhile, when the gas in the air bag unit 331 is released, the gas in the head-mounted device 300 can also flow, so that the use comfort of the head-mounted device 300 is improved.
Of course, it is understood that, in the embodiment of the present application, the number relationship between the controller 351 and the airbag unit 331 is not limited. For example, one controller 351 may correspond to a plurality of airbag units 331 at the same time, so as to realize the inflation and deflation control of the plurality of airbag units 331 by one controller 351. When one controller 351 corresponds to a plurality of airbag units 331, the number of switches in the controller 351 is not limited. For example, the controller 351 may be provided with one switch, and thus, it is possible to simultaneously control the plurality of airbag units 331 by one switch, at which time the plurality of airbag units 331 communicate with each other. For another example, the controller 351 may be provided with a plurality of switches, the number of the switches is the same as the number of the airbag units 331, that is, one switch corresponds to one airbag unit 331, and the plurality of switches may be used to independently control the plurality of airbag units 331. For another example, a plurality of switches may be disposed in the controller 351, and the number of the switches is smaller than the number of the airbag units 331, so that one part of the switches may correspond to one airbag unit 331, and the other part of the switches may correspond to one or more airbag units 331.
It is understood that, in the embodiment of the present application, the inflation and deflation mechanism 352 may further include an air pump controller 3523. The air pump controller 3523 is connected to the air pump 3521. The air pump controller 3523 is configured to monitor the air in the air storage balloon 3522, and then control the air pump 3521 to inflate the air storage balloon 3522 according to the monitoring result, so that the corresponding air is stored in the air storage balloon 3522. For example, when the air pump controller 3523 monitors that the air in the air storage balloon 3522 is insufficient, the air pump 3521 can be controlled to inflate the air storage balloon 3522 in time, so that sufficient air is always stored in the air storage balloon 3522.
It is understood that, in the embodiment of the present application, the specific inflation and deflation control manner of the air bag unit 331 is not limited, and can be selected according to specific requirements. For example, in a first scenario, the head-mounted device 300 may automatically control inflation and deflation of the support airbag 3311 in the airbag unit 331. For example, referring to fig. 7, the head-mounted device 300 further includes a pressure sensor 37. The pressure sensors 37 may be provided in the respective airbag units 331 and connected with the respective controllers 351. The pressure sensor 37 is used to detect the pressure in the air bag unit 331 in different areas to monitor the supporting position in real time, analyze the pressure distribution of different positions of the head-mounted device 300 during use, and transmit the analysis result to the controller 351. The controller 351 controls inflation and deflation of the support airbags 3311 in the respective airbag units 331 by the inflation and deflation mechanism 352 in accordance with the pressure detected by the pressure sensor 37. Thus, the pressure of the air bag unit 331 at different positions can be adjusted, and the change of the supporting position along with the time in the wearing process can be further realized.
It is understood that in the first scenario, one pressure sensor 37 may correspond to one airbag unit 331 and one controller 351. Thus, automatic adjustment of the airbag unit 331 of different areas can be achieved. When the air bag unit 331 includes two or more supporting air bags 3311, since the two or more supporting air bags 3311 can share one control unit 35, the inflation and deflation of the plurality of supporting air bags 3311 are simultaneously controlled by one control unit 35. Thus, in one embodiment, the two or more support bladders 3311 may also share a single pressure sensor 37. That is, the pressure sensor 37 may be provided in any one of the two or more supporting airbags 3311 to detect the gas pressure in the supporting airbag 3311 in the airbag unit 331.
It is understood that in further embodiments, when the air bag unit 331 includes a plurality of support air bags 3311, a respective pressure sensor 37 may also be disposed within each support air bag 3311 and connected to a respective controller 351. In yet another embodiment, when the head-mounted device 300 includes a multi-layer airbag mechanism 33, the airbag units 331 disposed at the same layer may share one pressure sensor 37 and the controller 351. In this case, the pressure sensor 37 may be provided at any one of the plurality of airbag units 331 disposed at the same level, and the plurality of airbag units 331 disposed at the same level are all connected to one controller 351. Thus, under the control of the controller 351, the air cell units 331 of the same layer can be controlled to be inflated and deflated automatically at the same time, thereby effectively saving the space and cost of the head-mounted device 300.
As another example, in the second scenario, the head-mounted device 300 may manually control inflation and deflation of the support airbag 3311 in the airbag unit 331. In particular, the head-mounted device 300 may also include a control interface (e.g., a user interface of a display unit). By adding the airbag inflation/deflation option to the control interface of the head-mounted device 300, inflation/deflation of the corresponding airbag unit 331 can be realized, and further, the support function for different positions can be realized. It is understood that the manual control mode may be determined visually by the interaction mode of the head-mounted device 300. For example, the manual control can be implemented by, but not limited to, a handle, a remote control, or a gesture.
For example, referring to fig. 8, in the second scenario, the head-mounted device 300 further includes a key module 39. The key module 39 is provided with a plurality of keys. Among them, in one embodiment, a plurality of keys are provided to control inflation and deflation of the airbag unit 331 in different regions, and the pressing time or the number of times of the plurality of keys is provided to control the thickness of the airbag unit 331 in different regions.
It is understood that in one embodiment, the key module 39 is a remote controller for controlling the head-mounted device 300. Thus, the settings and definitions can be made through the control interface on the headset 300. For example, one of the keys (for example, an up key) of the key module 39 may be configured to control inflation and deflation of one of the airbag units 331. Another key (e.g. a down key) of the key module 39 is configured to control inflation and deflation of another airbag unit 331. As another example, when one of the keys (for example, the up key) of the key module 39 is pressed for a preset number of times or a preset time, the inflation and deflation of one of the airbag units 331 and the thickness thereof (for example, the amount of inflation) may be controlled.
It is understood that, in the embodiments of the present application, the two manners may exist independently or simultaneously. For example, in one embodiment, the air inflation and deflation of the air bag unit 331 can be manually controlled only by the key module 39. In another embodiment, the automatic control of inflation and deflation of the air bag unit 331 may be achieved only by the pressure sensor 37. Alternatively, in another embodiment, the button module 39 and the pressure sensor 37 may be provided at the same time to manually and/or automatically control the inflation and deflation of the air bag unit 331.
Obviously, the embodiment of the present application provides a head-mounted device 300, by arranging the airbag unit 331 in different areas, so that the airbag unit 331 fits the contour of the head and face of the user. The head-mounted device 300 can achieve pressure adjustment of the gas inside the airbag unit 331 at different locations or areas, i.e., achieve area airbag pressure adjustment. Further, by providing the multilayer airbag mechanism 33 in the thickness direction thereof, the adjustment of the airbag mechanism 33 in the thickness direction, that is, the airbag thickness adjustment is realized by inflating and deflating the airbag mechanisms 33 of different layers with different pressures and volumes. Moreover, the head-mounted device 300 can automatically and/or manually implement dual adjustments of regional bladder pressure adjustment and bladder thickness adjustment to meet the needs of different facial people. Different positions and face contact can be realized through the regulation of different positions gasbag thickness, and alleviate the uncomfortable nature that oppresses for a long time that same position leads to, effectively promote the use travelling comfort of head-mounted device 100.
It should be understood that the embodiments of the present application may be arbitrarily combined, for example, may be used alone or may be used in combination with each other to achieve different technical effects, and the present application is not limited thereto.
The above description is only an embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions within the technical scope of the present disclosure should be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
