Detailed Description

The utility model will be further explained with reference to the drawings.

As shown in fig. 2 to 5, according to a first aspect of the present invention, there is provided a headband 1 having greater size adjustability. Specifically, the headband 1 includes a first side headband 20a, a second side headband 20b, and a rear headband 40, a first end of the first side headband 20a and a first end of the second side headband 20b being for connection with a user interface device, respectively; the rear headband 40 has both sides connected to the second ends of the first and

second side headband

20a and 20b, respectively, and when the headband is worn by a user, the first and

second side headband

20a and 20b extend in the direction from the left cheek to the upper left ear region and from the right cheek to the upper right ear region of the user, respectively, and the rear headband 40 surrounds the back of the brain of the user when worn.

The extending directions of the first side headband 20a and the second side headband 20b are respectively on the same straight line with the extending direction of the corresponding side of the rear headband 40. Thus enabling a greater range of adjustability of the headband 1. Specifically, a first end of the first side headband 20a is provided with a first adjustment structure 21, and a first end of the second side headband 20b is provided with a second adjustment structure 22; the first and

second adjustment structures

21 and 22 are used to adjust the in-use length of the first and

second side headgear

20a and 20b, respectively, to adjust the tightening force of the user interface device.

Taking the first adjusting structure 21 and the second adjusting structure 22 as magic tapes as an example, as shown in fig. 3 and 4, the first adjusting structure 21 and the second adjusting structure 22 respectively pass through the corresponding connecting holes 60 on the main body 100 and then are folded and attached to the outer side surfaces of the first side head band 20a and the second side head band 20b in opposite directions, so that the first side head band 20a forms a first opposite folding part 25, and the second side head band 20b forms a second opposite folding part 26. Since the adjustment of the first and second

side head straps

20a and 20b plays a major role in wearing the user interface device, the length of the first and second

side head straps

20a and 20b used can be adjusted by folding them back, thereby adjusting the binding force of the user interface device.

As described above, since the extending directions of the first and

second side headband

20a and 20b are substantially in line with the extending directions of both sides of the rear headband 40, respectively, the first and

second side headband

20a and 20b have a greater adjustment range D1 than the conventional easy-to-use headband, i.e., the adjustment range of the first and

second side headband

20a and 20b is D1+ D2 (as shown in FIGS. 2 and 4). In other words, the rear headband 40 also becomes part of the adjustment. Thus, the adjustment capability of the headband 1 is much better than that of the conventional Y-type headband.

Furthermore, the value range of D1 is 70mm-150mm, preferably 85mm-120 mm. It will be appreciated that the adjustment range D1 is the distance from the first side headband 20a to the connection between the top headband 30 and the rear headband 40 described below, or the distance from the second side headband 20b to the connection between the top headband 30 and the rear headband 40 described below. In other words, the distance is measured in the extending direction of the first side headband 20a or the second side headband 20 b.

It will be appreciated that the first and

second adjustment structures

21 and 22 may also be other connecting structures such as snaps, magnets, snaps, and clasps.

Wherein, the width W of the first side head band 20a is 12mm-16 mm; the width W of the second side headband 20b is 12mm-16 mm. Note that the "width" is a dimension in a direction perpendicular to the extending direction of the first side headband 20a or the second side headband 20b, as shown in fig. 2. Too wide or too narrow a width may cause discomfort to the wearer, for example too narrow a width may cause local strangulation to the face and head of the user, while too wide a width may cover too much skin of the user. The first and

second side headbands

20a, 20b within the above-described width range can therefore improve the wearing comfort of the user while ensuring that the user interface device is tightly secured to the user's face.

Optionally, a third adjustment structure is provided on the rear headband 40 for adjusting its length of use. The third adjustment structure may be similar to the first adjustment structure 21 and the second adjustment structure 22, such as a hook and loop fastener, a buckle, a magnetic device, a snap fastener, or other connecting structures, so as to further adjust the length of the headband 1.

Wherein, the length of the rear head band 40 is 200mm-260mm, and the rear head band 40 within the length range can meet the head circumference size requirement of most people.

The headband 1 of the present invention further comprises a top headband 30, both ends of the top headband 30 are respectively connected with both sides of a rear headband 40; as shown in FIG. 2, the included angle α between the headband 30 and the rear headband 40 is 30 ° -150 °; preferably 75-85 deg., so that the rear headband 40 and the top headband 30 can be securely coupled to the user's head.

Since the top head strap 30 can also serve as an auxiliary adjustment, a fourth adjustment structure 34 is provided to adjust its length of use.

The fourth adjustment structure 34 includes a connecting member provided on one of the first end strap 32 and the second end strap 33 and a mating member provided on the other of the first end strap and the second end strap, the mating member being in mating connection with the connecting member.

For example, the connecting member and the mating member may be a hook and loop fastener, a snap, a magnet, a snap, a buckle, or other connecting structures.

In one embodiment, the connecting member is a headband buckle 31 disposed on the first end band 32, the mating member is a magic tape disposed on the second end band 33, the magic tape passes through the headband buckle 31 and is reversely folded and attached on the outer side surface of the second end band 33, and the actual tightening force of the top headband 30 can be adjusted by reversely folding the length. The fourth adjustment structure 34 is the same as the above adjustment structure, and can adjust the length of the headband 30, thereby being suitable for users with different head circumference sizes.

Further, in the embodiment where the fourth adjustment structure 34 is provided, the length of the headband 30 is 190mm to 310mm, preferably 230mm to 270 mm. Wherein, the length of the top belt 30 is: the hook and loop fastener of the second end strap 33 is passed through the headband button 31, and is adhered after being folded back closest to the root to connect the first end strap 32 and the second end strap 33, at which the both ends of the top headband 30 and the rear headband 40 are unfolded in length (or can be understood as an arc length between the both ends of the top headband 30). In an alternative embodiment, as shown in fig. 5, no adjustment structure is provided on the top head belt 30, which can reduce the cost.

Further, in this embodiment without the adjustment structure, the length of the headband 30 is 190mm to 310mm, preferably 230mm to 270 mm. It will be appreciated that in this embodiment, the length of the top head strap 30 is the extended length from the intersection of its two ends with the rear head strap 40 (or may be understood as the arc length between the two ends of the top head strap 30).

Further, in the above preferred or alternative embodiment, the length of the first end band 32 and the length of the second end band 33 may be set to be unequal for ease of adjustment. As shown in fig. 3, the length of the first end strap 32 provided with the hook and loop fastener may be greater than the length of the second end strap 33.
