The drawings are intended to provide a further understanding of the present disclosure, and constitute part of the description. The drawings are intended to interpret the present disclosure along with the embodiments of the present disclosure, and do not function to limit the present disclosure. In the drawings:
In order to make the objects, the technical solutions and the advantages of the present disclosure clearer, the present disclosure will be described below in conjunction with the drawings.
Referring to
In some embodiments, two sets of the head-mounted portion length adjustment mechanisms are symmetrically connected to two ends of the body of the head-mounted portion 1, respectively, so as to achieve the adjustment of the length of the head-mounted portion 1. Referring to
In some embodiments, the display leg 21 is provided with a leg length adjustment mechanism. Referring to
During the adjustment, a person may push or pull the extendable rod 212 to continuously compress or stretch the spring 5 to change the length. The upper surface or the lower surface of the extendable rod 212 is provided with plastic elastic protuberances, so that a person can easily overcome the resistance of the extendable rod 212 to adjust the length. When the length is changed to reach an appropriate position, the person releases his hand, and the extendable rod 212 is correspondingly clamped outside the elongated slot by the external plastic elastic protuberances to realize the positioning, thereby meeting people's requirement on wearing comfort.
Referring to
In order to make the ear cup bracket rotation portion 312 and the ear cup bracket fixing portion 311 rotate around the same vertical axis, a first blind hole is opened in the ear cup bracket fixing portion 311, a second blind hole is opened in the ear cup bracket rotation portion 312, and a rotation shaft is inserted into the first blind hole and the second blind hole, so as to realize the rotatable connection between the ear cup bracket rotation portion 312 and the ear cup bracket fixing portion 311. Thus, the ear cup 32 and the sound generator therein can rotate around the axis in the vertical direction to realize the rotation in a plane. When a user wants to store the adjustable head-mounted display, he may rotate the ear cup 32 to an appropriate position according to his demands for a deposition. For example, in the existing adjustable head-mounted display, the ear cup 32 and the sound generator therein are mostly fixed rather than rotatable. During travel, it is difficult for people to put the head-mounted display into a suitcase and a large space will be occupied. However, if the head-mounted display of the embodiment is used, the two ear cups 32 can be rotated by 360 degrees around the vertical axis, and when an appropriate position is reached, the head-mounted display is put into the suitcase, which is convenient, efficient and space saving.
In some embodiments, the head-mounted portion 1 is entirely made of a cambered bent strip, which matches with the cambered head of the human body, thereby facilitating the wearing on the human body, and improving the wearing comfort.
In order to realize the refractive accommodation function when the adjustable head-mounted display is worn, a front-back adjusting assembly is provided in the display portion 2 to drive the display to move forward and backward. The refractive accommodation is mainly made by adjusting the distance between the lens module and the display. The lens module is generally fixed on the bracket, and thus the above distance is changed by adjusting the longitudinal separation of the display, so as to complete the refractive accommodation. The forward and backward movement of the display is mainly realized by the front-back adjusting assembly. In the embodiment, the front-back adjusting assembly mainly comprises a threaded rod and a threaded knob, wherein the threaded rod is fixedly connected to the display, and the threaded knob is in threaded connection with the threaded rod to drive the threaded rod to move forward and backward by the rotation of the threaded knob, thereby driving the display to move forward or backward to realize the refractive accommodation. In order to perform refractive accommodations for the two eyes corresponding to the two ends of the display, respectively, threaded knobs are symmetrically provided at the two sides of the bottom of the display to rotatably drive the display to move.
In some embodiments, the display portion 2 comprises a display frame, a lens module and a supporting platform, wherein an adjustment slot is opened in the display frame, the supporting platform is fixedly connected to the lens module, an adjustment block is provided below the supporting platform, the adjustment block slides back and forth along the adjustment slot, the adjustment block is connected to the supporting platform, and the lens module is fixed with the supporting platform, wherein when the adjustment block slides back and forth along the adjustment slot opened in the display frame, the lens module is driven to move, and the pupil distance between the two eyes can be adjusted by adjusting the adjustment blocks symmetrically provided at the two ends of the display portion 2 by sliding.
