The gear body 310 is connected to the strap part 200 and can be rotated to adjust the length of the strap part 200 . That is, the gear body 310 is a gear operation unit 312 that rotates according to the operation of the strap connection unit 311 and the motor or gear handle 340 connected to the strap unit 200 from the outside of the noise prevention mechanism 320. can be distinguished. Here, the strap connection unit 311 is connected to the strap unit 200 in a rack and pinion method as shown in FIG. 3 to adjust the length of the strap. In addition, the gear operating unit 312 may be a portion covered by the anti-noise mechanism 320, as shown in FIG.

The anti-noise mechanism 320 has a cylindrical shape, a wedge 321 is formed on the inner surface of the cylinder, and may cover the gear body 310. As shown in FIG. 6, the anti-noise mechanism 320 covers the gear operating part 312 of the gear body 310 so that the “tick-tack” sound generated when the gear operates is not transmitted loudly to the outside. .

More specifically, as shown in FIGS. 7 and 8 , a plurality of wedges 321 may be formed on the inner surface of the cylinder of the anti-noise mechanism 320 . In particular, the wedge 321 may be formed at a position engaged with the gear arm 330 .

Here, the anti-noise mechanism 320 is coated with SF urethane on the inner surface to prevent noise. More specifically, the material of the anti-noise mechanism 320 is PC with excellent impact resistance to prevent wear of the wedge 321, but SF urethane coating serves to prevent noise, and the gear arm 330 Noise generated when contacting the wedge 321 can be minimized.

Gear arm 330, one end is connected to the gear body 310, the other end may be a shape engaged face-to-face with the wedge 321 formed on the inner surface of the anti-noise mechanism 320. More specifically, as shown in FIG. 8 , the gear arm 330 has a rectangular cross section in the longitudinal direction, and can minimize noise generated when passing over the wedge 321 .

9 is a view showing a cross section of a conventional gear. Comparing the cross-section of the gear of the present invention in FIG. 8 with the cross-section of the conventional gear in FIG. 9, the low-noise gear unit 300 of the head-mounted display device 10 equipped with the low-noise gear for strap adjustment according to an embodiment of the present invention Since the shape of the gear arm 330 is configured in a rectangular shape, and the amount of bouncing while returning to the original position over the wedge 321 is different from the conventional one, noise is reduced compared to the gear of the structure shown in FIG. can be minimized.

The length of the strap part 200 may be adjusted by controlling the motor.

The distance measuring unit 500 may include a distance measuring sensor 510 located on the back of the wearer's head when worn by the wearer and measuring a distance from the wearer's head. For example, as shown in FIG. 2 , the distance measurement unit 500 is located inside the low-noise gear unit 300 and can measure the distance to the back of the wearer's head.

More specifically, the distance measurement unit 500 may include a distance measuring sensor 510 that measures the distance to the wearer's head by irradiating laser light and a proximity sensor 520 that recognizes whether or not the wearer is wearing it. . Here, the distance sensor 510 is a sensor that measures the distance by irradiating light such as a laser and measuring the return time, and the proximity sensor 520 measures the location when an object approaches. It is a sensor that detects

The control unit 400 may control the low-noise gear unit 300 according to the distance measured by the distance measurement unit 500 so that the strap unit 200 is adjusted to fit the wearer's head. That is, the control unit 400 drives the ultra-precision motor that operates the low-noise gear unit 300 based on the sensing data of the distance measuring sensor 510 and the proximity sensor 520 constituting the distance measuring unit 500 to drive the strap unit. The length of (200) can be adjusted.

More specifically, the control unit 400 calculates the rotation direction and number of rotations of the ultra-precision motor so that the distance measurement unit 500 approaches the wearer's head as much as the distance measured by the distance measurement unit 500, and the calculated rotation direction And it is possible to control the low-noise gear unit 300 according to the number of revolutions.

Meanwhile, when recognizing the wearing of the wearer using the measurement data of the proximity sensor 520, the controller 400 transmits a distance measurement command to the distance measurement sensor 510, and according to the distance measured by the distance measurement sensor 510. The low-noise gear unit 300 may be controlled. In addition, the control unit 400 may control the low-noise gear unit 300 to an initial state before the wearer wears it when recognizing that the wearer takes off the head-mounted display device 10 using measurement data of the proximity sensor 520. there is. That is, it is possible to determine whether the wearer is wearing the head-mounted display device 10 through the proximity sensor 520, and the control unit 400 controls the length of the strap unit 200 to be extended or shortened according to the determination result. can do.
