Referring to fig. 1-3, the present invention provides VR glasses for conveniently adjusting an object distance and a pupil distance, and the VR glasses include a housing 100, where the housing 100 includes a front shell 101 and a bottom shell 102. The face shell 101 and the bottom shell 102 are buckled to form a mounting cavity 103.

The mounting cavity 103 is internally provided with a mounting frame 10, a pupil distance adjusting mechanism 20 and an object distance adjusting mechanism 30.

A left ocular 11 and a right ocular 12 are arranged in the mounting rack 10. Pupil distance adjustment mechanism 20 locates on the mounting bracket 10 for adjust left eyepiece 11 with interval between the right eyepiece 12 to satisfy different consumers will according to self demand left eyepiece 11 with right eyepiece 12 is adjusted to suitable wearing position.

The interpupillary distance adjusting mechanism 20 includes a first gear 21, a first rack 22, and a second rack 23. Wherein, the first rack 22 is connected with the left ocular lens 11, and the second rack 23 is connected with the right ocular lens 12.

The first and

second racks

22 and 23 are respectively engaged with the first gear 21 and located at opposite sides of the first gear 21, so that the first and

second racks

22 and 23 are relatively interlocked.

Specifically, the first gear 21 is a concentric gear and is disposed in the vertical direction such that the tooth surfaces of the first rack 22 and the second rack 23 are engaged on opposite sides of the first gear 21 in the vertical direction.

The first gear 21 includes a first wheel 211 and a second wheel 212, and the axes of the first wheel 211 and the second wheel 212 coincide with each other. Wherein opposite sides of the first wheel 211 are engaged with the first and

second racks

22 and 23, respectively, and the diameter of the first wheel 211 is smaller than the diameter of the second wheel 212.

The object distance adjusting mechanism 30 comprises an object distance adjusting wheel 31 and a screw rod 32, one end of the screw rod 32 is connected to the mounting frame 10, and the other end of the screw rod 32 penetrates through the object distance adjusting wheel 31 and is in threaded connection with the object distance adjusting wheel 31.

The object distance adjusting wheel 31 is circular and partially protrudes out of the housing 100, so that a consumer can adjust the object distance of the VR glasses outside the housing 100. The screw rod 32 is driven by rotating the object distance adjusting wheel 31 to drive the mounting frame 10 to move along the axial direction of the screw rod 32. Therefore, the object distance of the left ocular 11 and the right ocular 12 can be adjusted, and the object distance adjusting requirement of a consumer can be met.

Still be provided with fixed plate 104 in the casing 100, object distance adjusting wheel 31 keeps away from one side of mounting bracket 10 has fixed part 311, the rotatable restriction of fixed part 311 is in on the fixed plate 104, makes object distance adjusting wheel 31 be in can pivot under the restriction of fixed plate 104, makes to rotate when rotating object distance adjusting wheel 31, screw 32 drives mounting bracket 10 is close to or keeps away from object distance adjusting wheel 31.

The interpupillary distance adjusting mechanism 20 further includes a bar-shaped second gear 24 engaged with the first gear 21. The second gear 24 is engaged with the second gear 212, and the second gear 24 is arranged parallel to the axial direction of the screw 32, and the second gear 24 is axially slidably connected with the mounting bracket 10. Wherein the axial length of the second gear 24 is not less than the length of the screw 32.

The second gear 24 further has an adjusting portion 241, the adjusting portion 241 is circular and partially extends out of the housing 100, and rotating the adjusting portion 241 makes the second gear 24 rotate to drive the first gear 21 to rotate, so that the left eyepiece 11 and the right eyepiece 12 move relatively.

The face shell 101 is located on a side of the consumer that is close to the consumer's face when wearing the VR glasses. Two through holes 105 are formed in the face shell 101, and the two through holes 105 are respectively opposite to the left ocular lens 11 and the right ocular lens 12.

Parallel to the axial direction of the screw 32, the inner surface of the face shell 101 is further provided with a guide rod 106, and the mounting frame 10 is provided with a guide hole 13. The guide rods 106 pass through the guide holes 13 and are connected to the fixing plate 104. When the object distance adjusting mechanism 30 is adjusted, the mounting frame 10 will slide along the axial direction of the guide rod 106, so as to avoid the mounting frame 10 from shifting during movement, which results in the shifting of the left eyepiece 11 and the right eyepiece 12.

The use method is as follows: will VR glasses are worn at the head to it is just right to guarantee both eyes through-hole 105, through rotating regulating part 241 drives first gear 21 rotates, makes first rack 22 with the motion of second rack 23, in order to adjust left eyepiece 11 with distance between right eyepiece 12, through rotating object distance regulating wheel 31 drives screw rod 32 rotates, makes mounting bracket 10 is towards keeping away from or being close to object distance regulating wheel 31's direction removes, in order to adjust left eyepiece 11 with distance between right eyepiece 12 and the consumer's both eyes.
