Technical Field

[0001] The utility model relates to the technical field of wearable devices, and in particular to an intelligent head-mounted device. Background Art

[0002] At present, in order to meet the needs of myopic people, many smart head-mounted devices have a diopter adjustment function.

[0003] There are two main ways to adjust the diopter of smart head-mounted devices in the prior art. One is to adjust the position of some lenses in a multi-lens system to change the focal length of the optical system, thereby achieving diopter adjustment; the other is to adjust the distance from the screen to the last lens in a single-chip system or a lens system without space adjustment, thereby achieving diopter adjustment.

[0004] Both of the above two diopter adjustment methods are achieved by adjusting the relative positions of components. However, in the above two diopter adjustment processes, the individual focusing of the left and right optical lenses can only make the images on the left and right screens correctly focused. If the images on the screens are not adjusted accordingly, it is very easy to cause the image sizes seen by the user's two eyes to be inconsistent, resulting in a more obvious ghosting problem for the user, which seriously reduces the user experience. Utility Model Content

[0008] Among them, a focusing outer ring is rotatably sleeved outside the lens barrel, and a focusing inner ring linked to the focusing outer ring is axially movably sleeved inside the lens barrel. The focusing outer ring and the focusing inner ring are both coaxially arranged with the lens barrel, the focusing lens is arranged on the focusing inner ring, and the displacement sensor is arranged between the focusing inner ring and the lens barrel.

[0009] Among them, the inner focusing ring is provided with a radially extending driving column, the lens barrel is provided with an avoidance groove for avoiding the driving column, the outer focusing ring is provided with a spiral guide groove, the driving column passes through the avoidance groove and is inserted in the spiral guide groove, and the displacement sensor detects the position change of the focusing lens by detecting the position change of the driving column.

[0010] Wherein, the displacement sensor is a resistive, capacitive, electromagnetic, optical signal or laser displacement sensor.

[0011] Wherein, a linear guide structure is arranged between the lens barrel and the inner focusing ring.

[0012] Wherein, the linear guide structure comprises a linear guide groove and a linear guide block which cooperate with each other, the linear guide groove is arranged on the inner wall of the lens barrel, and the linear guide block is arranged on the outer wall of the inner focusing ring.

[0013] Wherein, a rotation guide structure is arranged between the focusing outer ring and the lens barrel.

[0014] Wherein, the rotation guide structure comprises a rotation guide groove and a rotation guide block which cooperate with each other, the rotation guide groove is arranged on the inner wall of the focusing outer ring, and the rotation guide block is arranged on the outer wall of the lens barrel.
