Description

Technical Field

[0001] The utility model relates to the technical field of VR display equipment, and in particular to a head-mounted VR display equipment. Background Art

[0002] VR (Virtual Reality) technology uses computer simulation to create a three-dimensional virtual world, providing users with simulation of senses such as vision, making users feel as if they are in the scene and can observe things in the three-dimensional space instantly and without restrictions. VR head-mounted display devices are also called VR headsets, VR helmets, VR glasses, etc.

[0003] The existing head-mounted display device includes two optical modules, which correspond to the left eye and right eye of the user respectively. Each optical module includes a lens module and a display module. The light emitted by the display module will be refracted through the lens module to form an enlarged virtual image that falls within the visible range of the user's eyes. However, since many users are myopic and the degree of myopia varies greatly, each optical module is usually equipped with a function of adjusting the diopter, that is, adjusting the distance between the lens module and the display module until the user's eyes can clearly see the presented virtual image.

[0004] In the prior art, the display module in the optical module is usually designed to be fixed as a whole with the base, and the lens module is designed to be movable. When adjusting the diopter, the lens module is rotated to achieve the lens module being close to or away from the display module. The lens module of this structure has the problem of being large in size, so that the optical module has the disadvantages of being large in size and heavy in weight, which does not meet the user's demand for a small size and light weight of the head-mounted display device. Moreover, when adjusting the diopter, due to the large size of the optical module of this structure, the two optical modules cannot be brought close to a smaller distance, so that the adjustment range of the pupil distance of the two optical modules is greatly limited.

[0035] Among them: the helmet body 10 is worn on the human head through the suspension structure 11, the helmet body 10 is a light Kevlar helmet, the suspension structure 11 includes a first webbing and a second webbing, the ends of the first webbing and the second webbing opposite to each other are both connected to the helmet body 10, the opposite ends of the first webbing and the second webbing are connected by a buckle structure, that is, the end of the first webbing away from the helmet body 10 is movably connected to the end of the second webbing away from the helmet body 10 through the buckle structure, and the buckle structure is a prior art, so it is not described here. At the same time, the cooperation of the suspension structure 11 and the buckle structure is used to realize the standard Kevlar helmet wearing method of the helmet body 10.

The VR display component, the displacement component and the adjustment component are all connected to the mounting base 51. It should be noted that the mounting shell is connected to the helmet body 10 through a dual-axis structure 60. Through the dual-axis structure 60, the VR glasses 50 can be adjusted in angle relative to the vertical plane to accommodate more people.

[0037] In this embodiment, the VR display component includes a lens structure 21 and a display module 22. The lens structure 21 is connected to the display module 22. The display module 22 is used to display images. The lens structure 21 is used to refract the light emitted by the display module 22 to form a virtual image. The adjustment component is connected to the display module 22 to drive the display module 22 to approach or move away from the lens structure 21 through the adjustment component to achieve the refractive power of the VR display component. At the same time, the displacement component is connected to the VR display component, and the displacement component is used to drive the lens structure 21 and the display module 22 to move synchronously to adjust the position of the lens structure 21 to achieve the adjustment of the pupil distance of the VR display component.

[0038] In this embodiment, the displacement assembly includes a card joint, a limit plate 42 and a driving member. The card joint is connected to the lens structure 21, and the limit plate 42 is connected to the helmet body 10 through the mounting shell. Specifically, the limit plate 42 is connected to the top of the mounting shell, and a plurality of limit grooves 421 are provided on the limit plate 42. The limit plate 42 is located above the lens structure 21. The limit plate 42 and the mounting base 51 are respectively located on the opposite sides of the lens structure 21.

The driving member is used to drive the mounting base 51, the lens structure 21, the card joint and the display module 22 to move along the length direction of the limit plate 42, so that the card joint is correspondingly engaged with different limit grooves 421, wherein the limit plate 42, the card joint, the lens structure 21, the mounting base 51 and the driving member are arranged in sequence from top to bottom.

[0039] It can be understood that the mounting base 51 , the lens structure 21 and the display module 22 are driven by the driving member to move synchronously, so as to ensure that the real-time positions of the lens structure 21 and the display module 22 correspond.

[0040] It should be noted that a through slot is formed on the mounting shell, and one end of the driving member away from the mounting base 51 passes through the through slot and extends to the outside of the mounting shell.

It should be noted that in order to smoothly connect the snap joint with different limit grooves 421, the end of the snap joint 411 away from the elastic part 413 is designed to be an arc surface, and the side wall of the snap joint 411 is fitted with the inner wall of the receiving groove. When the driving member drives the lens structure 21 and the snap joint to move synchronously, under the influence of external force and the limitation of the inner wall of the receiving groove, the elastic part 413 is compressed, so that during the movement, the snap joint 411 withdraws from the current limit groove 421 and then connects with other limit grooves 421.

[0042] In this embodiment, the receiving portion 412 is a block-shaped structure, the clamping portion 411 is a semi-cylindrical structure, and the elastic portion 413 is a telescopic spring.

[0043] In this embodiment, the driving member is a toggle block 431 and a limiting structure. One end of the toggle block 431 in the driving member is connected to the side wall of the mounting base 51 away from the lens structure 21. The limiting structure is connected to the toggle block 431. The limiting structure is located in the through groove. There are two limiting structures. The two limiting structures are respectively located on the opposite sides of the toggle block 431. The opposite sides of the toggle block 431 are respectively connected to the two opposite groove walls of the through groove through the two limiting structures. It can be understood that the limiting structure is used to limit the toggle block 431.

[0044] It should be noted that the limiting structure includes a limiting block 432 and a limiting spring 433. A receiving groove is opened on the groove wall of the through groove. The limiting spring 433 and part of the limiting block 432 are both located in the receiving groove. One end of the limiting spring 433 is connected to the bottom of the receiving groove, and the other end of the limiting spring 433 is connected to the limiting block 432. The end of the limiting block 432 away from the limiting spring 433 is connected to the toggle block 431.

[0045] In this embodiment, the adjustment component includes a compression spring 31, a traction rope 32 and a winding wheel 33. A mounting groove is opened on the mounting base 51. The compression spring 31 is located in the mounting groove. One end of the compression spring 31 is connected to the inner wall of the mounting groove. The other end of the compression spring 31 is connected to the display module 22 through the sliding block 34. Specifically, the top of the sliding block 34 is connected to the bottom of the display module 22, the side wall of the sliding block 34 is connected to the compression spring 31, the sliding block 34 is located in the mounting groove, one end of the traction rope 32 passes through the compression spring 31 and is connected to the center of the sliding block 34, the other end of the traction rope 32 is connected to the winding wheel 33, and the winding wheel 33 is installed on the end of the toggle block 431 away from the mounting base 51.

[0046] It can be understood that by rotating the winding wheel 33 to tighten the traction rope 32, the compression spring 31 is compressed under the pulling of the traction rope 32, and the display module 22 is driven close to the lens structure 21 through the sliding block 34. By rotating the winding wheel 33 in the opposite direction and loosening the traction rope 32, the display module 22 can be driven away from the lens structure 21, thereby realizing the diopter adjustment operation.

[0047] It should be noted that the winding wheel 33 is rotatably connected to the end of the toggle block 431 away from the lens structure 21 , the toggle block 431 is provided with a through hole, and the end of the traction rope 32 away from the sliding block 34 is connected to the winding wheel 33 through the through hole.

[0048] In this embodiment, in order to limit the rotation of the winding wheel 33, an obstruction block 434 is provided on the toggle block 431, and the obstruction block 434 is movably connected to the toggle block 431 through a torsion spring. A blind hole 35 is provided on the winding wheel 33, and one end of the obstruction block 434 is inserted into the blind hole 35 to prevent the rotation of the winding wheel 33. It should be noted that the obstruction block 434 is an L-shaped structure, and a pull ring 435 is connected to the end of the obstruction block 434 away from the torsion spring. It can be understood that when the winding wheel 33 needs to be rotated, the pull ring 435 is used to pull the obstruction block 434 away from the end of the torsion spring, so that the obstruction block 434 is tilted away from the end of the torsion spring and exits the blind hole 35.

[0049] In this embodiment, a speaker assembly is disposed in the helmet body 10, and the speaker assembly includes two speaker structures 70 and a connecting bracket. The two speaker structures 70 are respectively connected to the two ends of the connecting bracket. Both speaker structures 70 are connected to the helmet body 10 through the connecting bracket, that is, the connecting bracket is connected to the helmet body 10, and the two speaker structures 70 are respectively close to the left ear and the right ear of the human head.

[0050] In a specific implementation, the limiting plate 42 is connected to the lens structure 21, a limiting groove 421 is opened on the limiting plate 42, and the driving member is used to drive the lens structure 21 to move along the length direction of the limiting plate 42, so that the clamping joint drives the different limiting grooves 421 on the limiting plate 42 to be clamped accordingly to adjust the position of the lens structure 21 and adjust the pupil distance of the VR display component. Then, the adjusting component is connected to the display module 22, and the adjusting component is used to drive the display module 22 to be close to or away from the lens structure 21 to adjust the refractive power of the VR display component. This is not only beneficial to reducing the volume of the lens structure 21 in the VR display component, but also beneficial to expanding the range of pupil distance adjustment of the VR display component.

[0051] It should be noted that the above implementation process is only for illustrating the feasibility of the present application, but this does not mean that the head-mounted VR display device of the present application has only the above-mentioned implementation process. On the contrary, as long as the head-mounted VR display device of the present application can be implemented, it can be included in the feasible implementation plan of the present application.
