BACKGROUND OF THE INVENTION

Field of the Invention

The present invention generally relates to a headband adjusting assembly, and more particularly to a headband adjusting assembly which is applied in a head-mounted display device.

Description of Related Art

In general, a head-mounted display device is able to be used in a virtual reality (VR), an augmented reality (AR), a mixed reality (MR), etc. The virtual reality constructs a highly realistic 3D (Three Dimensional) virtual world by use of a computer simulation way. The augmented reality projects virtual elements into a reality by used of a projection way or a camera combination way. A technology of the mixed reality combines both a VR technology and an AR technology. With the improvement of sciences and technologies, the head-mounted display devices are becoming more and more popular in applications of a medicine field, a military field, an entertainment field, an education field and other fields. In order to adapt to head sizes of different users, the head-mounted display devices are usually equipped with headband adjusting assemblies for adjusting lengths of headbands, so that the users may easily adjust the headbands by themselves to the appropriate lengths for enhancing wearing comfort levels of the users.

A conventional headband adjusting assembly includes a head frame and a headband. The head frame abuts against two opposite sides of a head and a forehead of a user. The headband is connected with two opposite ends of the head frame. The headband surrounds a rear of the head of the user, and the headband abuts against the rear of the head of the user. The two opposite ends of the head frame have two through holes penetrating through the two opposite ends of the head frame, respectively. Two opposite ends of the headband have two hook and loop fasteners, respectively. One ends of the two hook and loop fasteners are defined as two free ends of the two hook and loop fasteners. The one ends of the two hook and loop fasteners of the two opposite ends of the headband pass through the two through holes, respectively, and then the one ends of the two hook and loop fasteners of the two opposite ends of the headband are folded towards the other ends of the two hook and loop fasteners to make the one ends of the two hook and loop fasteners adhered to the other ends of the two hook and loop fasteners, so that a length of the headband is adjustable.

However, when the headband is pulled by an external force, the two hook and loop fasteners are easily torn from the headband on account of insufficient combining forces of the two hook and loop fasteners on the headband, the two hook and loop fasteners of the two opposite ends of the headband break away from the two through holes to affect a stability between the headband and the head frame, and then an inconvenience of the user is caused. Furthermore, after the conventional headband adjusting assembly is worn to the head of the user, the length of the headband is hardly adjusted by virtue of designs of the two hook and loop fasteners, in that case, if the user wants to adjust the length of the headband slightly, the user need take off the conventional headband adjusting assembly to adjust the length of the headband.

In view of the above-mentioned drawbacks, it is essential to provide an innovative headband adjusting assembly which is applied in a head-mounted display device. The headband adjusting assembly adjusts an overall length of a headband unit conveniently, and the headband adjusting assembly has an advantage of improving a wearing stability of the head-mounted display device.

The overall length of the headband unit 5 is adjusted by virtue of adjusting the length of the first headband 3 and the length of the second headband 4. The first elastic block 251 is buckled with or breaks away from one of the plurality of the first penetrating grooves 322 and the second penetrating grooves 422. The second elastic block 252 is buckled with or breaks away from another one of the plurality of the first penetrating grooves 322 and the second penetrating grooves 422.

Referring to FIG. 1 to FIG. 7, when the first adjusting portion 32 is pulled towards a rightward direction by the user, the first headband 3 moves rightward. The first elastic block 251 is guided by the guiding surface 253 of the first elastic block 251 to make the first elastic block 251 slide out of the plurality of the first penetrating grooves 322. The length of the first headband 3 is adjusted, the wearing space 101 becomes smaller, so the first headband 3 is attached to the head of the user more tightly. When the second adjusting portion 42 is pulled towards a leftward direction by the user, the second headband 4 moves leftward. The second clastic block 252 is guided by the guiding surface 253 of the second elastic block 252 to make the second clastic block 252 slide out of the plurality of the second penetrating grooves 422. The length of the second headband 4 is adjusted, the wearing space 101 becomes smaller, so the second headband 4 is attached to the head of the user more tightly. The first headband 3 and the second headband 4 adjust the overall length of the headband unit 5 to enlarge or reduce the wearing space 101 according to the size of the head circumference of the user.

When the user wants to take off the head-mounted display device 300, the finger of the user stirs the first operation portion 232 of the first elastic structure 23 by the first concave groove 233, so the first elastic structure 23 is elastically deformed to break away from the first headband 3. The first elastic block 251 breaks away from the first buckling portion 321 of the first headband 3, and the first clastic block 251 is separated from the plurality of the first penetrating grooves 322 by the guiding surface 253 of the first elastic block 251. At the moment, the first headband 3 of the headband unit 5 is released to be pulled outward, the length of the first headband 3 is adjusted, the wearing space 101 becomes bigger, so the first headband 3 is attached to the head of the user more loosely. The finger of the user stirs the second operation portion 242 of the second elastic structure 24 by the second concave groove 243, so the second elastic structure 24 is elastically deformed to break away from the second headband 4. The second clastic block 252 breaks away from the second buckling portion 421 of the second headband 4, and the second clastic block 252 is separated from the plurality of the second penetrating grooves 422 by the guiding surface 253 of the second elastic block 252. At the moment, the second headband 4 of the headband unit 5 is released to be pulled outward, the length of the second headband 4 is adjusted, the wearing space 101 becomes bigger, so the second headband 4 is attached to the head of the user more loosely. The user takes off the head-mounted display device 300 conveniently.

Then, when the user releases the first operation portion 232, the first elastic structure 23 is rebounded towards the first headband 3 of the headband unit 5 to be restored to an original position of the first elastic structure 23, so the first elastic structure 23 is close to the first headband 3. The first elastic block 251 is buckled with the first buckling portion 321, so the first clastic block 251 prevents the first headband 3 being completely separated from the main body 1. When the user releases the second operation portion 242, the second elastic structure 24 is rebounded towards the second headband 4 of the headband unit 5 to be restored to an original position of the second elastic structure 24, so the second elastic structure 24 is close to the second headband 4. The second clastic block 252 is buckled with the second buckling portion 421, so the second elastic block 252 prevents the second headband 4 being completely separated from the main body 1. In that case, when the user wears the head-mounted display device 300, the user pulls the headband unit 5 towards different directions to adjust the wearing space 101 so as to make the headband unit 5 attached to the head of the user more tightly or more loosely.
