The invention provides a head-mounted adjusting device.

In an embodiment of the present invention, as shown in fig. 1, 4 and 5, the head mount adjustment device includes:

anair bag bandage 100, which is internally provided with an inflationinner cavity 101; and

theair pump 300 is communicated with the inflationinner cavity 101, and theair pump 300 is used for executing air inlet action and air outlet action;

when theair pump 300 performs the air intake action, theair pump 300 inflates the inflationinner cavity 101; when theair pump 300 performs the air discharging action, theair pump 300 draws air from theinflation cavity 101.

In the present invention, theair pump 300 can control the air content in theinflation cavity 101 by supplying or discharging air, so as to change the degree of expansion of theairbag band 100, thereby adjusting the tightness of the head-mounted display device. Specifically, when theair pump 300 performs the air intake action, theair pump 300 will intake air from the external environment to inflate theinflation cavity 101, so that during the air intake of theair pump 300, the air content of theinflation cavity 101 increases, the air pressure increases, and theairbag band 100 will also swell, i.e. the head-mounted display device can be tightened; when theair pump 300 performs the air exhausting action, theair pump 300 will draw air from theinflation cavity 101 and exhaust the air to the external environment, so that during the air exhausting process of theair pump 300, the air content in theinflation cavity 101 decreases, the air pressure decreases, and theairbag band 100 will contract and deflate, i.e. the head-mounted display device can be loosened. Therefore, the head-wearing adjusting device can conveniently adjust the tightness of the head-wearing display equipment, theair bag strap 100 of the head-wearing adjusting device does not have too strong constraint feeling on the head of a human body, the wearing comfort of a user can be improved, and the use experience of the user can be greatly improved.

Further, in this embodiment, the head-mounted adjusting device further includes anair pressure sensor 200, and theair pressure sensor 200 is configured to detect the air pressure of theinflation cavity 101. In this embodiment, wear adjusting device and still addbaroceptor 200,baroceptor 200 can detect the atmospheric pressure of aerifinginner chamber 101 to provide more accurate regulation foundation for the user, thereby realize wearing the quantization of display device's elasticity and adjust. It is understood that the magnitude of the air pressure can reflect the degree of expansion of theairbag band 100, which is directly related to the tightness of the head-mounted display device. Thus, when the tightness of the head-mounted display device is adjusted, the head-mounted adjusting device can capture the adaptive air pressure corresponding to the adaptive tightness through theair pressure sensor 200, and the deviation between the finally obtained tightness and the adaptive tightness can be reduced or even eliminated only by controlling the air pressure of the inflatableinner cavity 101 to reach the adaptive air pressure. Therefore, the adjustment precision of the head-mounted adjusting device is improved, the tightness of the head-mounted display equipment can be more adaptive, and the use experience of a user is improved.

Further, in the present embodiment, as shown in fig. 5, theair pump 300 has abalance chamber 310 communicated with theinflation lumen 101, and at least the sensing probe of theair pressure sensor 200 is located in thebalance chamber 310. It is understood that the gas has a certain flow rate during the intake process or the exhaust process of thegas pump 300, and the flow rate of the gas affects the gas pressure detection result. In the embodiment, thebalance chamber 310 is additionally disposed in theair pump 300, and thebalance chamber 310 is communicated with theinflation cavity 101, that is, the air pressure in thebalance chamber 310 can reflect the air pressure of theinflation cavity 101, therefore, theair pressure sensor 200 can indirectly obtain the air pressure of theinflation cavity 101 by detecting the air pressure of thebalance chamber 310, the detection result of theair pressure sensor 200 is not affected by the air intake or exhaust of theair pump 300, the detection accuracy of theair pressure sensor 200 is improved, and a more accurate control basis can be provided for a user. Of course, in other embodiments, theairbag strap 100 may have a balance chamber communicated with theinflation cavity 101, and the sensing probe of theair pressure sensor 200 may extend into the balance chamber to detect the air pressure of theinflation cavity 101 more accurately.

Further, in this embodiment, the head-mounted adjusting device is further provided with a voice module, the voice module is used for recognizing a voice command, and theair pump 300 acts according to the voice command. The actions of theair pump 300 include opening, closing, air intake, air exhaust, etc., and the user can make theair pump 300 act as required by voice control. Thus, even when the user wears the head-mounted display device, the tightness of theairbag band 100 can be continuously adjusted through voice control, and the convenience of adjustment is greatly improved. It can be understood that the head-mounted display device is further provided with a speaker for playing sound externally, and further, in this embodiment, the voice module can also output voice through the speaker to confirm a voice instruction or feed back a control result to a user, so as to improve the interactivity of the voice control function. Of course, in other embodiments, the head-mounted adjusting device may not be provided with a voice module, but the devicemain body 20 is provided with a voice module, so that voice control can be realized; or, theair pump 300 may be operated differently by different touch commands like a bluetooth headset, and thus, the tightness may be continuously adjusted without removing the head-mounted display device.

Further, in this embodiment, when the air pressure fed back by theair pressure sensor 200 is equal to the protection air pressure, theair pump 300 does not perform the air intake operation any more, so as to protect the personal safety of the user. The protection air pressure is set by considering the maximum air pressure which can be borne by the airbag binding band 100 so as to avoid explosion of the airbag binding band 100 caused by overlarge air pressure in the inflationinner cavity 101; the maximum tolerance tightness of the human body is also considered, so that the head of the user is prevented from being tightened excessively, and discomfort is brought to the user.

Further, in this embodiment, when theairbag strap 100 is adjusted in place, the head adjustment device records the air pressure value detected by theair pressure sensor 200 and stores it for recall by the user. Optionally, the head-mounted adjusting device further stores tolerance air pressure values of people with different head circumferences, and when the user wears the head-mounted display for the first time, the tolerance air pressure values can be adjusted to gradually control theair pump 300 to inflate, so that the air pressure of theinflation cavity 101 reaches different tolerance air pressure values one by one, and the user is asked one by one whether to continue to inflate until an air pressure value suitable for the user is found. If the adaptation air pressure of the user is not met in the tolerance air pressure value stored by the head-mounted adjusting device, a closer tolerance air pressure value can be found firstly, the tightness of the head-mounted display device is made to be close to the adaptation tightness, then the head-mounted display device is finely adjusted to the adaptation air pressure so as to adjust the head-mounted display device to the adaptation tightness, meanwhile, the air pressure value at the moment is recorded and stored by the head-mounted display device, so that the air pressure value can be directly called when the user wears the head-mounted display device subsequently, and the air pressure value does not need to be adjusted step by step.

Further, in the present embodiment, theair pump 300 performs different actions according to the air pressure fed back by theair pressure sensor 200 to realize negative feedback adjustment. When the air pressure fed back by theair pressure sensor 200 reaches the target air pressure, theair pump 300 stops the air intake or the air exhaust, so that theair pump 300 can respond quickly, thereby ensuring the adjustment accuracy of the head-mounted adjustment device. Of course, in other embodiments, the air pressure fed back by theair pressure sensor 200 may be only used for displaying, and the user may view the displayed air pressure value and control theair pump 300 to perform different actions by means of manual control.

Further, in the present embodiment, as shown in fig. 2 and 3, theairbag strap 100 includes anairbag 110 and a first outer covering 120 covering theairbag 110, and theairbag 110 has theinflation cavity 101. The firstouter wrapper 120 may function to protect theairbag 110 to prevent theairbag 110 from being damaged and deflated. The firstouter covering cloth 120 may be made of cloth, leather, rubber, or the like.

Further, in the present embodiment, a buffer layer is provided between the firstouter cover 120 and theairbag 110. The cushioning layer may further protect theair bag 110, and may also improve the softness of theair bag strap 100, so that the wearing comfort and user experience of the user may be further improved. Optionally, the buffer layer may be a sponge filled between the firstouter wrapping cloth 120 and theairbag 110, and at this time, theairbag 110 is further wrapped with a mylar sheet to protect theairbag 110 sufficiently; alternatively, the foam of the cushion layer may be produced by EPP foaming or EPE foaming, in which case, theairbag 110 is filled in the foam of the cushion layer, and the firstouter cover 120 is wrapped outside the foam of the cushion layer.

Further, in the present embodiment, as shown in fig. 2 and 4, theairbag band 100 includes afirst communication pipe 130 and a plurality ofairbags 110 connected in series, and twoadjacent airbags 110 are communicated through thefirst communication pipe 130.

Further, in this embodiment, as shown in fig. 4 and 5, the head-mounted adjustment device further includes asecond communication pipe 140, one end of thesecond communication pipe 140 is communicated with theair pump 300, and the other end thereof penetrates through the middle portion of theairbag band 100 and is communicated with theinflation cavity 101. Thus, theair pump 300 inflates or evacuates air to both sides of theinflation cavity 101 at the middle position of theinflation cavity 101, and the inflation or evacuation efficiency can be effectively improved. Without loss of generality, in this embodiment,battery compartment 400 is located in the middle ofairbag bandage 100, so that when a user wears the head-mounted display device,battery compartment 400 is located at the rear side, anddevice body 20 is located at the front side, so that the overall weight distribution is uniform, and the wearing comfort of the user can be improved. Thus, the length of thesecond communication pipe 140 can be shortened to reduce the distance from theair pump 300 to theinflation cavity 101, thereby further improving the inflation or air extraction efficiency of theair pump 300.
