As shown in fig. 1 and 2, the present embodiment provides a head-mounted device, in this embodiment, a VR device, where the head-mounted device includes a main body casing 1, and the main body casing 1 is used to mount an XR host.

The head-mounted device of the present embodiment further includes two flexible headband 2 disposed opposite to each other, and one end of each flexible headband 2 is fixedly connected to one end of the main body housing 1, respectively. The flexible headband 2 is capable of applying pressure to the user's head so that the friction of the head-mounted device with the user's head balances the weight of the head-mounted device itself.
As shown in fig. 1, 2, 3 and 4, each flexible headband 2 includes a band-shaped backing plate 24 and an integrally formed airbag assembly. The band-shaped backing 24 is a flexible sheet and can be folded. When the user wears the head-mounted device, the band-shaped lining plate 24 can be attached to the head of the user, the band-shaped lining plate 24 has certain elasticity, the surface of the band-shaped lining plate is rough, and the friction force between the band-shaped lining plate and the head of the user is ensured under the condition that the wearing comfort of the user is ensured. The air bag module is made of elastic material and comprises a strip-shaped substrate 21, more than two partition plates 222, more than two air bags 22 and a miniature air pump 23. The tape substrate 21 is attached to the surface of the tape backing 24; two or more partition plates 222 are provided at intervals on the surface of the strip-shaped base plate 21 on the side away from the strip-shaped liner 24, each partition plate 222 is provided with at least one vent hole 223, and the vent holes 223 allow the interiors of two air bags 22 adjacent to each other to communicate with each other. The plurality of air bags 22 are sequentially arranged on the surface of the strip-shaped base plate 21, which is far away from the strip-shaped lining plate 24, the air bags 22 are in the shape of a cylinder, and the cross section of the cylinder is rectangular or trapezoidal. Each balloon 22 includes a pair of opposing flexible walls 221, and in any two adjacent balloons 22, one flexible wall 221 of one balloon 22 and one flexible wall 221 of the other balloon 22 are connected to the same spacer 222 with a gap 224 between the two flexible walls 221. When the air bags 22 are inflated, the air pressure inside each air bag 22 is equal due to the presence of the vent holes 223, the middle portion of the flexible wall 221 of each air bag 22 protrudes outward, and the flexible walls 221 of the adjacent two air bags 22 are tangent to each other. The length of the plurality of air bags 22 is changed, and the lengths of the band-shaped base plate 21 and the band-shaped lining plate 24 are not changed significantly while the plurality of air bags 22 are extended, so that the band-shaped base plate 21 and the band-shaped lining plate 24 are bent, and the two flexible headband 2 and the main body casing 1 can enclose a containing space.
The airbag module is divided into three regions along the extending direction of the strip-shaped substrate 21, namely a first region 211, a second region 212 and a third region 213 in this order. With the extending direction of the strip-shaped substrate 21 as the first direction, the width of the partial air bags 22 located in the same region in the first direction is the same, the width of the air bags 22 in the first region 211 in the first direction is larger than the width of the air bags 22 in the second region 212 in the first direction, and the width of the air bags 22 in the second region 212 in the first direction is larger than the width of the air bags 22 in the third region 213 in the first direction. With the extending direction perpendicular to the strip-shaped substrate 21 as the second direction, the thicknesses of the partial air bags 22 located in the same region in the second direction are the same, the thickness of the air bags 22 in the first region 211 in the second direction is larger than the thickness of the air bags 22 in the second region 212, and the thickness of the air bags 22 in the third region 213 in the second direction is larger than the thickness of the air bags 22 in the second region 212 in the second direction.
When the flexible headband 2 is bent, since the lengths of the band-shaped base plate 21 and the band-shaped backing plate 24 are not significantly changed, the degree of bending of the band-shaped base plate 21 and the band-shaped backing plate 24 is related to the sum of the elongations of the plurality of air bags 22 per unit length, and the sum of the elongations of the plurality of air bags 22 per unit length is related to the elongation of each air bag 22. Because the inside of each airbag 22 is communicated due to the presence of the vent holes 223, the air pressure inside each airbag 22 is the same after each airbag 22 is filled with air. The amount of elongation after inflation of each balloon 22 is related to the shape and area of flexible wall 221 when the air pressure is unchanged. In the present embodiment, the flexible walls 221 of all the balloons 22 are provided in a rectangular or trapezoidal shape, so that the amount of elongation after inflation of each balloon 22 is positively correlated with the area of the flexible wall 221.

The sum of the elongations of the plurality of air cells 22 per unit length of each zone is inversely related to the dimensional length of the air cells 22 in the zone in the direction along which the strip-shaped base plate 21 and the strip-shaped liner 24 extend.
