After definition helmet is close to the side of user's head, before the side far from user's head is.
By Fig. 1 to Fig. 4 it is found that the VR display module includes guide rod 11, is mounted on guide rod 11 and can distinguish
The barrel assembly 12a that slides along guide rod 11 and barrel assembly 12b and it is separately positioned on barrel assembly 12a, barrel assembly
Display component 13a, display component 13b on front side of 12b, between barrel assembly 12a and display component 13a, barrel assembly 12b with
Simple eye focal length setting mechanism is respectively equipped between display component 13b;The simple eye focal length setting mechanism includes being connected to barrel assembly
At least two threaded rods 21 for extending between display component and along the longitudinal direction are mounted on threaded rod 21 and are located at barrel assembly
Driving wheel 22 on the end of side and the drive mechanism being arranged between at least two driving wheels 22, every threaded rod 21
It is separately mounted on barrel assembly and can relatively rotate with barrel assembly and be sequentially connected with display component.
Since barrel assembly 12a and barrel assembly 12b, display component 13a and display component 13b are independently arranged, and
And at least two screw threads are respectively equipped between barrel assembly 12a and display component 13a, barrel assembly 12b and display component 13b
Bar 21 is equipped with drive mechanism between the driving wheel 22 at least two threaded rods 21, can be tied by driving wheel 22 and transmission
Structure adjusts the distance between ipsilateral barrel assembly 12a and display component 13a, barrel assembly 12b and display component 13b
Section, the purpose focused is realized with this, solves the problems, such as that the focal length of helmet can only be adjusted simultaneously, can be according to user
Two eyesight degree are adjusted respectively, and use is very convenient.
In the present embodiment, the threaded rod 21 of each simple eye focal length setting mechanism is respectively arranged with three, three threaded rods
21 are separately positioned at the top, lower part and outside portion of barrel assembly;Driving wheel 22 is gear, drive mechanism is tooth belt
23, it is driven it is of course also possible to be equipped with multiple intermediate gears between adjacent two gear.
Since three gears are separately positioned at the top, lower part and outside portion of barrel assembly, it is therefore desirable on top
It is respectively equipped with belt steering structure between gear and the gear of outside portion, between the gear of lower part and the gear of outside portion, the skin
It include the outside tumbler 14 being arranged on barrel assembly, inside tumbler 15, the outer side band of tooth belt 23 with steering structure
Body is on tumbler 14 on the outside, inner band body is wound on the tumbler 15 of inside, and specifically, outside tumbler 14 is arc
Plate, inside tumbler 15 are cylindrical body.
In general, distinguishing between the gear of outer side and the gear on top, between the gear of outside portion and the gear of lower part
Equipped with tooth belt 23;The gear of outside portion be stepped gear wheel, two tooth belts 23 be looped around its it is small through wheel on, certainly, top
Gear, lower part gear the form of stepped gear wheel also can be set into.
In the present embodiment, barrel assembly 12a, barrel assembly 12b respectively include cylinder 121, are arranged in 121 big end of cylinder
Mounting plate 122 at mouthful outer side edges and the eyeglass being mounted at 121 portlet of cylinder, correspond to every spiral shell on mounting plate 122
