It should be noted that the front end and the rear end of the lens barrel outer frame 28 can be distinguished by the direction of the wearer's line of sight, that is, the rear end is close to the wearer's eyes, and the front end is far away from the wearer's eyes. In other words, the The front end of the lens barrel outer frame 28 is far away from the eye, and the rear end of the outer frame is close to the eye.

In this implementation, the method adopted is that the front shell 29 is arranged at the front end of the lens barrel outer frame 28 , and the rear shell 29 a is arranged at the rear end of the lens barrel outer frame 28 .

It can be understood that the front shell 29 and the rear shell 29a can be set according to actual usage requirements.

In this implementation, in order to ensure the comfort of the arc-shaped structure 281 of the lens barrel outer frame 28 and the wearer's eyes, and to avoid the pressure on the eye skin caused by long-term wearing, the A protective tape is provided on the arc structure 281 of the lens barrel outer frame 28 , or the protective band is arranged on the rear case 29 a matching the arc structure 281 of the lens barrel outer frame 28 .

Wherein, setting the protective band 281a on the arc structure 281 of the lens barrel outer frame 28 is based on omitting the rear case 29a.

In this implementation, the provided protective belt 281a can also ensure that the lens barrel mechanism 20 fits closely with the wearing position of the wearer, avoiding light leakage and affecting the use effect.

The above is a detailed description of the lens barrel mechanism 20 in the present utility model. It can be understood that, for the various components of the lens barrel mechanism 20, the installation and fixing method can be in the form of buckles or bolts. The form of fixing, etc., for some components, can be fixed by utilizing the fixed relationship between two components, for example: display screen and so on.

As shown in Figure 2, the head-mounted frame 10 in the head-mounted virtual reality display device provided by the present invention includes:

Head circumference fixing belt 11, the two ends of described head circumference fixing belt 11 are respectively connected to the both sides of described lens barrel outer frame 28, form the space that accommodates wearer's head along the wearer's head circumference direction, and described head The circumference fixing belt 11 can be stretched and adjusted according to the size of the wearer's head circumference.

The two ends of the head circumference fixing band 11 can pass through the provided through holes, which are matched with the holes provided on both sides of the lens barrel outer frame 28, and the bolts are screwed in to realize the connection and fixation of the two, and can The circumference size of the head circumference fixing belt 11 is adjusted by unscrewing the bolts.

It can be understood that the circumference size of the head circumference fixing belt 11 can not only be adjusted by its two ends and the two sides of the lens barrel outer frame 28, but also can be adjusted by setting a predetermined telescopic adjustment amount on the head circumference fixing belt 11. Realize, for example: reserve a part of the adjustment belt, and realize the adjustment through the groove of the protrusion of the reserved part of the adjustment belt and the matching of the head circumference fixing belt 11 or through the groove of the reserved part of the adjustment belt and the The matching protrusions of the head circumference fixing belt 11 can be adjusted. In fact, there are many adjustment methods. The above content is only an example to illustrate that the head circumference fixing belt 11 can be sized according to the head circumference of different wearers. adjustment.

The adjustment method can also be realized by setting the head circumference fixing belt 11 in the form of a hook and loop.

In order to ensure the safety and comfort of the wearer, a protective pad 12 corresponding to the position behind the wearer's head is provided on the head fixing belt, so as to reduce the wearing of the head circumference fixing belt 11. pressure on the patient's head.

In order to improve the stability of wearing, the head-mounted frame 10 also includes:

Head fixing belt 13, one end of the head fixing belt 13 is connected with the head circumference fixing belt 11 positioned at the rear of the wearer's head, and the other end of the head fixing belt 13 is connected with the lens barrel outer frame 28 upper connection.

The crown fixing belt 13 and the head circumference fixing belt 11 are integrally formed to accommodate the space of the wearer's head, thereby preventing the lens barrel mechanism 20 from slipping during use.

Similarly, in order to further improve the stability of wearing, an upper shell 131 and a lower shell 132 are arranged on the top of the top of the head fixing belt 13, and the upper shell 131 and the lower shell 132 are matched, and the top of the head is fixed. A portion of the belt 13 is clamped between the two.

In order to improve the comfort of the head fixing belt 13 and the wearing position, a head protection layer 1321 is provided on the side of the lower shell 132 facing the head.

In this implementation, the protective belt 281a, the protective liner 12 and the protective layer 1321 can be made of foam, and the total weight of the device is about 480g, thereby reducing the pressure on the wearing part and reducing the pressure on the wearing part. In case of external force, improve cushioning.

In this implementation, the left display screen 25 and the right display screen 26 respectively select display screens with a refresh rate of 90 Hz and/or a resolution of 1080x1200, preferably AMOLED display screen technology, to improve viewing comfort and reduce dizziness the emergence of.

The AMOLED is an abbreviation of English Active Matrix/Organic Light Emitting Diode, which means: Active Matrix Organic Light Emitting Diode panel. Compared with traditional LCD panels, AMOLED has the characteristics of faster response, higher contrast, and wider viewing angle.

In this implementation, the left lens 21 and the right lens 22 respectively select lenses with viewing angles in the range of 120 degrees, which not only improves the clarity but also reduces the distortion angle.

Although the utility model is disclosed as above with preferred embodiments, it is not used to limit the utility model, and any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model should be defined by the claims of the utility model.
