In this embodiment, the two VR barrels 20 are respectively disposed on two side edges of the supporting frame 10, and the two VR barrels 20 are respectively inserted into two horizontal sliding slots on the two side edges through the two hanging lugs 21, the supporting frame 10 can support the two VR barrels 20, meanwhile, the two VR barrels 20 slide in the two horizontal sliding slots to achieve the purpose of sliding in the two horizontal sliding slots in the opposite directions, and the two VR barrels 20 make the distance between the two VR barrels 20 match the interpupillary distance between two eyes of a user through sliding in the opposite directions.
As shown in fig. 4 and 5, in order to achieve the effects of synchronous sliding and stepless pitch adjustment between two VR barrels 20, the embodiment of the present invention proposes a sliding plate 30 capable of synchronously driving two VR barrels 20. Specifically, the sliding plate 30 is provided with two inclined sliding grooves, the suspension lug 21 of each VR barrel 20 is provided with a pin shaft (including a first pin shaft 24 and a second pin shaft 25) extending to one inclined sliding groove, in the process that the sliding plate 30 slides vertically, the inclined sliding groove on the sliding plate 30 also slides vertically, the movement track of the inclined sliding groove can be divided into vertical movement and horizontal movement, and each VR barrel 20 can only slide horizontally under the constraint of the horizontal sliding groove on the suspension lug 21 and the support frame 10, so that in the process that the sliding plate 30 and the inclined sliding groove both slide vertically, the VR barrel 20 and the suspension lug 21 can only slide horizontally under the driving of the inclined sliding groove in order to maintain the same height.
It should be noted that, the embodiment of the present invention mainly solves the technical problem that the existing hierarchical speed regulation VR interpupillary distance regulation mechanism 100 has poor experience, and therefore, the embodiment of the present invention proposes that the sliding plate 30 drives the two VR lens barrels 20 to slide in the transverse direction or in the reverse direction, so as to achieve the purpose of stepless speed regulation, the sliding plate 30 may be set to be manually regulated, or may be set to be automatically driven by the driving device 40, and both the sliding plate 30 may be driven by the manual regulation sliding plate 30 and the driving device 40, so as to achieve the purpose of stepless speed regulation, and the structure of the sliding plate 30 and the driving method of the sliding plate 30 are described in detail below.

Specifically, the oblique acting force applied by the oblique sliding groove to the pin shaft and the hanging lug 21 can be divided into a vertical acting force and a transverse acting force, because the transverse sliding grooves have a vertical limiting function on the hanging lugs 21, and the vertical acting force exerted on the hanging lugs 21 by the transverse sliding grooves is opposite to the vertical acting force exerted on the hanging lugs by the inclined sliding grooves, namely, the resultant force exerted on the hanging lugs 21 by the inclined sliding grooves and the transverse sliding grooves is the transverse acting resultant force, the hanger 21 and the VR lens cone 20 are driven to slide along the transverse direction through the transverse acting resultant force applied to the hanger 21 by the inclined sliding chute and the transverse sliding chute, because the two inclined angles of the two inclined chutes on the sliding plate 30 are complementary, the two transverse forces applied to the two hanging lugs 21 by the two inclined chutes are opposite in direction, therefore, the purpose of driving the two VR lens barrels 20 to slide in the transverse direction or the reverse direction through the two inclined chutes on the sliding plate 30 is achieved.
It should be noted that the above embodiments do not limit the specific structure of the supporting frame 10 and the specific distribution of the two lateral sliding chutes and the two inclined sliding chutes, because the specific structure of the supporting frame 10 and the specific distribution of the two lateral sliding chutes and the two inclined sliding chutes include the following different embodiments: because two lateral sliding grooves need to be arranged on two sides of the support frame 10, the support frame 10 can be of a hollow square tube structure and can also be of a hollow channel steel structure; the two transverse sliding chutes can be arranged at the same height of the two side edges of the support frame 10, and can also be arranged at different heights of the two side edges of the support frame 10, when the two transverse sliding chutes are positioned at the same height, the two inclined sliding chutes are also positioned at the same height, and when the two transverse sliding chutes are positioned at different heights, the two inclined sliding chutes are also positioned at different heights; in addition, each lateral sliding groove may be formed to penetrate only one side of one sliding plate 30, or may be formed to penetrate both sides of the sliding plate 30.
