Head-mounted display and diopter adjusting device thereof

Abstract

The invention relates to a head-mounted display and a diopter adjusting device thereof. The head-mounted display is provided with a key, and a motor can be started to adjust diopter by lightly pressing the key, so that the operation is convenient; the motor adopts a stepping motor, the adjustment precision is high, the diopter adjustment can be accurate to + / -0.5 degrees, so that a user can more accurately adjust the diopter required by the user, and the user can wear the head-mounted display more comfortably; and by arranging a shading blade and a sensor, when the shading blade enters the sensor, the relative position of the rear seat frame assembly can be known through the feedback of a circuit signal, so that when the head-mounted display is turned on and off, the rear seat frame assembly can return to the pre-shutdown position quickly and realizes the reset of the turning on and turning off state, the initial adjustment time is reduced, and by arranging the diopter adjusting deviceof the left eye and the right eye on the main body part respectively, the single eye independent adjustment can correct the visual difference of the left eye and the right eye.

Description

technical field [0001] The invention relates to the technical field of intelligent hardware structure, and more specifically, relates to a head-mounted display and a diopter adjustment device thereof. Background technique [0002] In the design process of smart glasses products, the difference in vision of each eye is taken into account when users are inconvenient to wear glasses to watch, so they all have diopter adjustment lenses. [0003] Existing smart glasses products usually use manual monocular diopter adjustment or manual binocular diopter adjustment at the same time, which is prone to the problem that the left and right eye vision difference cannot be corrected; secondly, the existing diopter adjustment mainly has the following methods: (1 )Adopt built-in cams, threads, and external manual roller adjustment; (2) Adjust by sliding the front of the external toggle key; (3) Realize binocular simultaneous adjustment through the gear train, and external manual roller adj...

Problems solved by technology

[0003] Existing smart glasses products usually use manual monocular diopter adjustment or manual binocular diopter adjustment at the same time, which is prone to the problem that the left and right eye vision difference cannot be corrected; secondly, the existing diopter adjustment mainly has the following methods: (1 ) using built-in cam, screw thread, external manual roller adjustment; (2) front sliding adjustment through external toggle key; (3) simultaneous binocular adjustment through gear train, external manual roller adjustment

These adjustment methods not only have the problems of inconvenient operation and poor driving accuracy, but also can not be reset after the product is turned on and off, and the diopter needs to be adjusted again
