Description

Technical Field

[0001] The present invention relates to the technical field of VR glasses, and in particular to a pair of VR glasses that are convenient for adjusting pupil distance. Background Art

[0002] VR glasses provide users with a full range of highly immersive virtual reality experience. VR glasses are widely used in games, movies and other entertainment fields, bringing users a new interactive experience. What affects the visual experience of VR glasses is the adjustment of the center distance between the lenses inside the VR glasses. This distance is referred to as the pupil distance in the human body, that is, the distance between the centers of the pupils of the human eye. The pupil distance of a normal adult ranges from 58-64mm.

[0003] The existing VR glasses generally include fully automatic adjustment of interpupillary distance and manual adjustment of interpupillary distance. Although the fully automatic adjustment has the function of automatic adjustment, it is easily interfered by external factors during the adjustment of interpupillary distance, resulting in adjustment errors. For example, when the VR glasses with fully automatic adjustment of interpupillary distance adjust the interpupillary distance, if the user's head shakes and moves, it will cause the infrared sensor of the internal detection position to misjudge, resulting in that after automatic adjustment, the center distance of the lens cannot adapt well to the user's interpupillary distance. Therefore, the current market generally adopts the method of manual adjustment of interpupillary distance. Compared with automatic adjustment, manual adjustment is more controllable and user-friendly for users, especially by adjusting the interpupillary distance by themselves, users can better adapt to their own interpupillary distance, thereby obtaining a better VR experience.

[0004] At present, the manually adjustable interpupillary distance of VR glasses is generally adjusted by rotating an adjustment dial arranged on the outer shell of the VR glasses in cooperation with a precise screw and nut inside the VR glasses, to adjust the center distance of the two lenses. However, the adjustment dial in the prior art generally has a large adjustment range. The VR glasses generally have an initial lens center distance set after leaving the factory, and the user needs to start adjusting from the initial center distance before using the VR glasses. In this way, there is a large range of adjustment space between the initial center distance and the interpupillary distance that the user needs to adjust, which will cause the user to perform multiple trials and errors during the adjustment process, increasing the time and complexity of adjusting the interpupillary distance, and failing to meet the user's needs for convenient interpupillary distance adjustment.

[0005] Therefore, the present invention proposes a VR glasses that is convenient for adjusting the pupil distance to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0006] In view of the defects existing in the prior art, the present invention provides a VR glasses that are easy to adjust the pupil distance, which can effectively solve the technical problem that the VR glasses in the prior art that manually adjust the pupil distance still have the inconvenience of adjusting the pupil distance multiple times.

The wedge-shaped displacement block has an inclined surface on its top, and the bottom end of the wedge block sleeve spring rod is pressed and matched with the inclined surface on the top of the wedge-shaped displacement block. The bottom of the wedge-shaped displacement block is slidably connected to the upper surface of the VR glasses body through a spring frame, and the spring frame is fixedly connected to the upper surface of the VR glasses body. A spring 2 is connected between the side wall of the wedge-shaped displacement block and the inner wall of the spring frame.

A lock column is fixedly connected to the lock hole plate on one side of the torsion spring cover close to the linkage curved rod, and the lock column is plug-fitted with the lock hole plate.

[0015] Preferably, the end of the lock column close to the linkage bent rod is a smooth hemispherical surface, and the outer wall of the lock hole plate is a smooth surface.

[0016] Preferably, the damping limit mechanism also includes an abutment component, which includes a magnetic sheet one, and the magnetic sheet one is fixedly connected to the side surface of the torsion spring cover close to the strap, and the upper surface of the VR glasses body close to the strap is symmetrically provided with a spring mirror groove, and the inner wall of the spring mirror groove is slidably connected with a damping protrusion plate through a spring three sliding connection, and the center of the damping protrusion plate is fixedly connected with a magnetic sheet two, and the magnetic sheet two and the magnetic sheet one are both magnetic, and the magnetism of the magnetic sheet two is opposite to that of the magnetic sheet one, and the surface of the damping protrusion plate close to the adjusting dial is evenly fixedly connected with rod-shaped protrusions, and the surface of the adjusting dial close to the rod-shaped protrusions is evenly provided with circular holes with the same number as the rod-shaped protrusions.

[0017] Preferably, a protective auxiliary mechanism is further provided on the side of the VR glasses body close to the strap, and the protective auxiliary mechanism includes a rotating rod, which is threadedly connected to the upper surface of the VR glasses body close to the strap, and the lower end of the rotating rod passes through the upper surface of the VR glasses body and then extends to the side of the built-in partition close to the strap, and the lower end of the rotating rod close to the built-in partition is fixedly connected with a magnetic ball 1, and a positioning support plate fixedly connected to the outer wall of the built-in partition is provided directly below the magnetic ball 1, and the bottom of the built-in partition close to the side of the strap is fixedly connected with a slotted bottom plate, and the two ends of the slotted bottom plate are symmetrically slidably connected with magnetic sliders, and the magnetic sliders The upper surface of the slider is fixedly connected with a guard plate, which is made of a light plastic material that is translucent, and the surface of the guard plate is eye-protection green. The outer ring surface of the guard plate is fixedly connected with a magnetic ball 2, which is on the same horizontal plane as the positioning support plate. The magnetism of the magnetic ball 2 is opposite to that of the magnetic ball 1. When the magnetic ball moves down and contacts the upper surface of the positioning support plate, it is on the same horizontal line as the magnetic ball 2. That is, after the magnetic ball moves down, the magnetic ball 2 can be driven to move toward the side close to the magnetic ball 1 by utilizing the magnetic attraction effect of the opposite magnetism to the magnetic ball 2, so that the guard plate horizontally blocks the side of the VR lens close to the strap.

[0018] Preferably, the surfaces of the magnetic sliders on the side close to each other are magnetic and have the same magnetism. The repulsive force between the magnetic sliders is smaller than the magnetic attraction between magnetic ball two and magnetic ball one. When the magnetic ball moves down to the same horizontal line with magnetic ball two, the magnetic ball two can be forced to approach each other and remain relatively still. When the user manually rotates the rotating rod to force magnetic ball one to move up and reset, no magnetic attraction is generated between magnetic ball two and magnetic ball one. Therefore, under the action of the same magnetic repulsive force between the magnetic sliders, the guard plate can slide in the opposite direction and reset.

[0019] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0020] The VR glasses are provided with four distance adjustment slots, and three of the four distance adjustment slots correspond to three gears that can adjust the center distance between VR lenses. Therefore, when adjusting the pupil distance, the user can independently select one of the three gears according to his own needs, so that the center distance between the VR lenses can be quickly and conveniently adjusted within the set distance range. Compared with the prior art, when adjusting the pupil distance, the user needs to start from the initial center distance of the VR lenses and continuously rotate the adjustment dial within a large adjustment distance range to adjust the center distance between the VR lenses. When adjusting the VR glasses in this solution, the large range of pupil distance adjustment is divided into three gears that can be quickly adjusted. In this way, when adjusting the pupil distance, the user can quickly and conveniently lock the pupil distance that suits him, thereby improving the convenience of the pupil distance adjustment of the VR glasses and reducing the time spent by the user on adjusting the pupil distance, so that the user has a better VR experience.

[0021] By arranging a torsion spring cover that can be opened automatically just above the adjustment dial, the torsion spring cover automatically opens before the user adjusts the gear position, which is convenient for the user to perform subsequent fine-tuning of the interpupillary distance. When the VR glasses are not in use, that is, when the interpupillary distance adjustment is not required, the torsion spring cover is always in a locked state under the cooperation of the lock column and the lock hole plate, thereby reducing the situation in which the adjustment dial is worn and inconvenient to adjust due to external dust or impurities falling on the transmission part of the adjustment dial when the VR glasses are in use. In this way, the adjustment dial is effectively shielded and protected to ensure the adjustment effectiveness of the adjustment dial.

[0022] When the user uses the adjustment dial to adjust the interpupillary distance in a small range, at this time, because the rod-shaped protrusion on the surface of the damping protrusion plate is inserted into the circular hole on the surface of the adjustment dial, and the end of the rod-shaped protrusion is a hemispherical surface, when the user turns the adjustment dial, the rod-shaped protrusion inserted in the circular hole on the surface of the adjustment dial will play a role of limiting damping on the rotation of the adjustment dial, thereby preventing the user from turning the adjustment dial too much when adjusting the interpupillary distance, or too fast to cause damage to the adjustment dial, thereby avoiding the user's interpupillary distance adjustment failure. At the same time, by utilizing the hemispherical surface of the rod-shaped protrusion, when the user turns the adjustment dial, the hemispherical surface of the rod-shaped protrusion will continue to contact and squeeze with the inner wall of the circular hole, thereby providing real-time motion feedback when the user turns the adjustment dial, thereby facilitating the user to fine-tune the interpupillary distance;

[0023] After the user finishes using the VR glasses, without removing them, the user can relieve eye fatigue after watching the VR glasses by looking at the green guard plate, which is a color that is beneficial to eye recovery, and avoid eye discomfort after using the VR glasses. Thus, by looking at the green guard plate, damage to the user's eyes after using the VR glasses can be reduced;

[0024] At the same time, due to the horizontal displacement of the two magnetic balls, the guard plate horizontally blocks the side of the VR lens close to the strap. Therefore, after the user finishes using the VR glasses, the VR lens is immediately shielded and protected, thereby preventing external dust or impurities from falling on the surface of the VR lens, and preventing the user from accidentally scratching the surface of the VR lens, thereby reducing damage to the VR lens and ensuring clarity when the user uses the VR glasses subsequently.

[0050] Specifically, the adjusting screw 14 is a bidirectional screw with oppositely-directed threads on the outer walls at both ends, and the adjusting nut 15 and the adjusting screw 14 form a ball screw structure. As the adjusting screw 14 rotates, the adjusting nut 15 is driven to move closer to or farther from the outer wall of the adjusting screw 14. The adjusting nut 15 is slidably connected to the limiting concave plate 16. Specifically, a rod body is provided at the bottom of each adjusting nut 15, and a long hole is provided on the limiting concave plate 16.

That is, after the first magnetic ball 42 moves downward, the magnetic attraction with the opposite magnetism to the second magnetic ball 46 can drive the second magnetic ball 46 to move to the side close to the first magnetic ball 42, so that the guard plate 45 horizontally blocks the side of the VR lens 17 close to the strap 11;

[0069] Specifically, the surfaces of the magnetic sliders 44 that are close to each other are magnetic and have the same magnetism. The repulsive force between the magnetic sliders 44 is smaller than the magnetic attraction between the magnetic ball 46 and the magnetic ball 1 42. When the magnetic ball 1 42 moves down to the same horizontal line with the magnetic ball 2 46, the magnetic ball 2 46 can be forced to approach each other and remain in a relatively static state. When the user manually rotates the rotating rod 41 to force the magnetic ball 1 42 to move up and reset, no magnetic attraction is generated between the magnetic ball 2 46 and the magnetic ball 1 42. Therefore, under the repulsive force of the same magnetism between the magnetic sliders 44, the guard plate 45 slides in the opposite direction and resets.

[0070] The complete working principle and steps of the above embodiment are as follows:

[0071] Initial state limitation:

[0072] like Fig.13 As shown, initially, the distance block 29 is inserted into the distance adjustment slot 26 farthest from the adjustment dial 13. At this time, the center distance between the VR lenses 17 is 55 mm. The center distance is defined as the initial pupil distance of the VR lenses 17, and the distance adjustment slot 26 is used as a reference. The remaining three distance adjustment slots 26 correspond to the first, second, and third gears respectively.

[0073] like Fig.12 As shown, initially, the abutment head 32 is attached to the bottom of the inclined surface of the wedge block sleeve spring rod 3201, the lower end of the wedge block sleeve spring rod 3201 is attached to the top of the inclined surface of the wedge-shaped displacement block 34, the torsion spring cover 37 is closed, and the torsion spring at the rotation connection part between the torsion spring cover 37 and the VR glasses body 1 is in a stress-deformed state, the magnetic sheet 1 38 and the magnetic sheet 2 311 are attracted to each other, and the rebound force of the torsion spring at the rotation connection part between the torsion spring cover 37 and the VR glasses body 1 is greater than the magnetic attraction between the magnetic sheet 1 38 and the magnetic sheet 2 311, and the spring 3 in the spring mirror groove 39 is in a stretched state;

[0074] When using the step adjustment mechanism, refer to Figures 1 to 5 , Fig.11 , Fig.13 As shown:

[0075] When the user has finished wearing the VR glasses, the user manually moves the protective cover 21 in a direction away from the adjusting dial 13, and slides along the trajectory of the parallel grooves provided on the VR glasses body 1 to the end of the parallel grooves away from the adjusting dial 13, so that the shift dial 24 is completely exposed. Then, the user places a finger on the upper surface of the shift dial 24 and applies a force away from the adjusting dial 13, thereby causing the shift dial 24 to slide along the trajectory of the distance adjustment horizontal hole 22 away from the adjusting dial 13. The sliding displacement of the shift dial 24 will also synchronously drive the displacement slide shaft 23 to move synchronously. Since the displacement slide shaft 23 is fixedly connected to the adjusting nut 15 corresponding to its lower end, the adjusting nut 15 will also be synchronously driven to move.

[0076] Since the bottom of the adjusting nut 15 is slidably connected to the inner wall of the limiting concave plate 16 through the rod body, the adjusting nut 15 will be horizontally displaced along the trajectory of the limiting concave plate 16 under the limiting action of the limiting concave plate 16. Since the adjusting screw rod 14 is a bidirectional screw rod with opposite threads on the outer walls at both ends, and the adjusting nut 15 and the adjusting screw rod 14 form a ball screw structure, as the adjusting nut 15 fixedly connected to the lower end of the displacement sliding shaft 23 slides and displaces on the outer wall of the adjusting screw rod 14, it will drive the adjusting screw rod 14 to rotate. After the adjusting screw rod 14 rotates, the other adjusting nut 15 that is not fixedly connected to the displacement sliding shaft 23 will also be displaced. Fig.11 As shown, at this time, the adjusting dial 13 connected to the adjusting screw 14 will also be in a rotating state. In this state, the user does not need to use the adjusting dial 13 for adjustment. Note: The part where the adjusting screw 14 is connected to the adjusting dial 13 can be driven by two mutually meshing bevel gears. Specifically, one of the bevel gears is fixedly connected to the adjusting screw 14, and the other bevel gear is fixedly connected to the adjusting dial 13.

[0077] At the same time, when the user applies external force to cause the shift knob 24 to move away from the adjustment dial 13, at this time, Figure 5As shown, the distance block 29 is inserted into the distance adjusting slot 26 farthest from the adjusting dial 13 among the four distance adjusting slots 26, and the center distance between the VR lenses 17 is 55 mm. As the shift dial 24 drives the extension plate 25 to gradually move, the side wall of the distance adjusting slot 26 will be pressed and conflicted with the inclined surface of the distance block 29, so that the distance block 29 drives the center sleeve spring shaft 28 to slide horizontally in the receiving hole in the center of the positioning block 27 in the direction away from the distance adjusting slot 26. In this process, the control spring 2901 will be compressed. When the distance block 29 is completely separated from the distance adjusting slot 26, as the shift dial 24 continues to move, when the distance block 29 moves to the distance adjusting slot 26 position corresponding to the first gear, At this time, under the action of the rebound force of the reset spring, the center sleeve spring shaft 28 is forced to move in the reverse direction and reset, thereby causing the distance block 29 to be inserted into the distance adjustment slot 26 corresponding to the first gear. At this time, based on the initial center spacing of the VR lenses 17 being 55 mm, the shift knob 24 drives the extension plate 25 and the adjustment nut 15 fixedly connected to the displacement slide shaft 23 to move 2.5 mm in the direction away from the adjustment dial 13, while the other adjustment nut 15 not fixedly connected to the displacement slide shaft 23 moves 2.5 mm in the direction away from the adjustment dial 13. In this way, the initial center spacing of the VR lenses 17 being 55 mm is increased by 5 mm, and the center spacing between the VR lenses 17 is now 60 mm.

[0078] Based on the above situation, further explanation: Take the user's pupil distance of 62 mm as an example, at this time, the user can quickly determine the pupil distance that suits him / herself by turning the adjustment dial 13 and adjusting the distance of 2 mm again by the adjustment screw 14 to drive the adjustment nut 15. If the user perceives that his / her pupil distance is not suitable for 55 mm through eye observation during use, that is, the user's pupil distance is less than 55 mm, then after the user slides open the protective cover 21, there is no need to push the shift dial 24 to move. As the protective cover 21 is opened, the torsion spring cover 37 will automatically flip upward and open under the rebound force of the torsion spring. Note: The opening principle of the torsion spring cover 37 will be described in detail later, and then the pupil distance can be adjusted directly by turning the adjustment dial 13. If the user's interpupillary distance exceeds 65 mm, and the interpupillary distance is 68 mm, the user can push the shift dial 24 twice in succession after sliding open the protective cover 21, so that the shift dial 24 is inserted into the distance adjustment slot 26 corresponding to the second gear. At this time, the center distance of the VR lens 17 is 65 mm. Then the user can adjust the interpupillary distance by 3 mm by turning the adjustment dial 13 again. By analogy, the interpupillary distance corresponding to the distance adjustment slot 26 of the third gear is greater than 70 mm.

[0079] In the above process, when the user needs to make fine adjustments, the user can hold the center sleeve spring shaft 28 and pull it horizontally in the direction away from the extension plate 25. During this process, the reset spring is in a compressed state, and the horizontal movement of the center sleeve spring shaft 28 will cause the distance block 29 to move synchronously, causing the distance block 29 to move away from the inside of the distance adjustment groove 26 and gradually move into the accommodation hole opened in the positioning block 27. At this time, the distance block 29 no longer restricts the horizontal displacement of the shift knob 24 and the extension plate 25. That is, when the user turns the adjustment dial 13, the adjustment nut 15 can be driven to move horizontally on the outer wall of the adjustment screw 14 to achieve fine-tuning of the pupil distance.

[0080] The first effect of this embodiment being different from the prior art is that the VR glasses are provided with four distance adjustment slots 26, and three of the four distance adjustment slots 26 correspond to the three gears for adjusting the center distance between the VR lenses 17, so when the user adjusts the pupil distance, he can select one of the three gears according to his own needs, so that the center distance between the VR lenses 17 can be adjusted quickly and conveniently within the set distance range. Compared with the prior art, when the user adjusts the pupil distance, he needs to start from the initial center distance of the VR lenses 17, and continuously rotate the adjustment dial 13 within a larger distance range to adjust the center distance between the VR lenses 17, which is faster and more convenient. When adjusting the VR glasses in this solution, the large range of pupil distance adjustment is equally divided into three gears that can be quickly adjusted. In this way, when adjusting the pupil distance, the user can quickly and conveniently lock the pupil distance that suits him, thereby improving the convenience of the pupil distance adjustment of the VR glasses, reducing the time spent by the user to adjust the pupil distance, so that the user has a better VR experience.

[0081] When used in a limit damping mechanism, refer to Figure 1 , Figures 6 to 8 As shown:

[0082] Unlock the protection component:

[0083] As mentioned in the above process, when the user uses the three gears to adjust the pupil distance, it is also necessary to rotate the adjustment dial 13 to perform fine-tuning within a small range. Before the user adjusts the gear, the user manually moves the protective cover 21 in the direction away from the adjustment dial 13, and slides along the trajectory of the parallel groove to the end of the parallel groove away from the adjustment dial 13. In synchronization with this process, the outer wall of the protective cover 21 on the side away from the strap 11 is fixedly connected to the linkage bent rod 31, and the end of the linkage bent rod 31 is fixedly connected to the wedge block. The contact head 32 of the inclined surface of the sleeve spring rod 3201, and the contact head 32 is in the initial state fitted with the lowermost end of the inclined surface of the wedge sleeve spring rod 3201. Therefore, as the protective cover 21 drives the linkage bent rod 31 and the contact head 32 to move in the direction away from the adjusting dial 13, the contact head 32 will contact and squeeze the inclined surface at the upper end of the wedge sleeve spring rod 3201, thereby driving the wedge sleeve spring rod 3201 to vertically displace downward along the part slidingly connected to the limiting perforated plate 3202. In this process, the spring sleeve of the outer wall of the wedge sleeve spring rod 3201 will be compressed. The wedge block 3201 is compressed, and as the wedge block spring rod 3201 moves downward, the lower end of the wedge block spring rod 3201 is in contact with and squeezes the inclined surface of the wedge block 34, thereby causing the wedge block 34 to slide horizontally along the trajectory of the spring frame 33 in the direction away from the linkage bent rod 31. During this process, the spring 2 in the spring frame 33 will be compressed, and the horizontal displacement of the wedge displacement block 34 will also synchronously drive the lock column 35 to slide horizontally. , driving the lock column 35 to disengage from the inside of the lock hole plate 36. As the lock column 35 disengages from the inside of the lock hole plate 36, the torsion spring cover 37 will automatically flip upward and open under the action of the rebound force of the torsion spring, and the lock hole plate 36 will follow the torsion spring cover 37 to make an arc movement. In this way, when the user adjusts the pupil distance before using the VR glasses, the torsion spring cover 37 can be opened synchronously by sliding open the protective cover 21, so that the user can quickly adjust the gear to narrow the range of pupil distance adjustment, and then fine-tune it by turning the adjustment dial 13;

[0084] When the protective cover 21 continues to slide away from the adjusting dial 13, the contact head 32 is completely away from the upper inclined surface of the wedge sleeve spring rod 3201. At this time, the wedge sleeve spring rod 3201 will move up and reset under the rebound force of the spring 1. As the wedge sleeve spring rod 3201 moves up and resets, its lower end is no longer pressed against the inclined surface of the wedge displacement block 34. Therefore, the wedge displacement block 34 and the lock column 35 will slide back and reset under the rebound force of the spring 2.

[0085] When the user has finished experiencing the VR glasses, the user can hold the torsion spring cover 37 and turn it downward. During the downward turning of the torsion spring cover 37, the outer wall of the lock hole plate 36 will first contact and squeeze the hemispherical surface of the lock column 35. At this time, as the two squeeze and cooperate, under the guidance of the hemispherical surface of the lock column 35, the lock column 35 and the wedge-shaped displacement block 34 are caused to slide away from the linkage curved rod 31. In this process, the second spring is compressed again. When the lock hole plate 36 rotates downward with the torsion spring cover 37 to be flush with the lock column 35, the lock column 35 and the wedge-shaped displacement block 34 will be reset in the opposite direction under the rebound force of the second spring, thereby automatically completing the locking of the torsion spring cover 37.

[0086] Abutment components:

[0087] At the same time, in the process of the torsion spring cover 37 being flipped upward and opened, since the torsion spring cover 37 is fixedly connected with the magnetic piece 1 38 on the side surface close to the strap 11, and the inner wall of the spring mirror groove 39 is slidably connected with the damping protrusion plate 310 through the spring three, and the center of the damping protrusion plate 310 is fixedly connected with the magnetic piece 2 311, and the magnetic piece 2 311 and the magnetic piece 1 38 are both magnetic, and the magnetism of the two is opposite, and the surface of the damping protrusion plate 310 close to the adjusting dial 13 is evenly fixedly connected with a rod-shaped protrusion, the rod-shaped protrusion is made of rubber, and the end of the rod-shaped protrusion close to the adjusting dial 13 is a hemispherical surface, and the side surface of the adjusting dial 13 close to the rod-shaped protrusion is evenly opened with the same number of circular holes as the rod-shaped protrusion, so as the torsion spring cover 37 is flipped upward and opened, the magnetic piece 1 38 is driven to gradually move away from the magnetic piece 2 311, and at this time the two are no longer adsorbed, so that the damping protrusion plate 31 0 will drive the damping protrusion plate 310 to move horizontally along the track of the spring mirror groove 39 in the direction close to the adjusting dial 13 under the action of the contraction elastic force of the spring three, so that as the damping protrusion plate 310 moves in the direction close to the adjusting dial 13, the evenly arranged hemispherical surface of the rod-shaped protrusion will be inserted into the evenly opened circular hole on the surface of the adjusting dial 13. Since the end of the rod-shaped protrusion close to the adjusting dial 13 is made of rubber and has a hemispherical surface, when the user rotates the adjusting dial 13, the circular hole and the rubber part of the rod-shaped protrusion will be squeezed, thereby causing the part to deform. During the rotation of the adjusting dial 13, the rod-shaped protrusion is replaced and inserted into the circular hole opened in the adjusting dial 13, so as not to hinder the rotation of the adjusting dial 13, but only to play a damping role, thereby avoiding the excessive rotation of the adjusting dial 13, which leads to inaccurate fine-tuning of the interpupillary distance.

[0088] When the user finishes using the VR glasses and flips the torsion spring cover 37 downward to close it, during this process, the torsion spring cover 37 drives the magnetic sheet 1 38 to gradually approach the magnetic sheet 2 311, so that under the magnetic attraction of the opposite magnetism of the two, the damping protrusion plate 310 is driven to slide in the opposite direction along the track of the spring mirror groove 39 to reset, thereby causing the rod-shaped protrusion to leave the round hole. During this process, the spring 3 is in a stretched state;

[0089] This embodiment has the following effects compared to the prior art:

[0090] The VR glasses are provided with an automatically opened torsion spring cover 37 just above the adjustment dial 13. When the user adjusts the gear position, the torsion spring cover 37 is automatically opened, which is convenient for the user to perform subsequent fine-tuning of the pupil distance. When the VR glasses are not in use and the pupil distance does not need to be adjusted, the torsion spring cover 37 is always in a locked state under the cooperation of the lock column 35 and the lock hole plate 36, thereby reducing the situation in which external dust or impurities fall on the transmission part of the adjustment dial 13 when the VR glasses are in use, resulting in increased friction and inconvenience in adjustment of the adjustment dial 13 in subsequent use, thereby effectively shielding and protecting the adjustment dial 13 to ensure the adjustment effectiveness of the adjustment dial 13;

[0091] When the user of the VR glasses uses the adjustment dial 13 to adjust the pupil distance in a small range, the rod-shaped protrusion on the surface of the damping protrusion plate 310 is inserted into the circular hole on the surface of the adjustment dial 13, and the end of the rod-shaped protrusion is a hemispherical surface. Therefore, when the user rotates the adjustment dial 13, the rod-shaped protrusion inserted into the circular hole on the surface of the adjustment dial 13 will play a role of limiting damping on the rotation of the adjustment dial 13, thereby preventing the user from turning the adjustment dial 13 too much when adjusting the pupil distance, or causing damage to the adjustment dial 13 too quickly, thereby avoiding the user's pupil distance adjustment failure. At the same time, by utilizing the hemispherical surface of the rod-shaped protrusion, when the user turns the adjustment dial 13, the hemispherical surface of the rod-shaped protrusion will continue to contact and squeeze with the inner wall of the circular hole, thereby providing real-time motion feedback when the user turns the adjustment dial 13, thereby facilitating the user to fine-tune the pupil distance.

[0092] When using auxiliary protective devices, refer to Figure 1 and Figures 9 and 10 As shown:

[0093] When the user has finished experiencing the VR glasses, the user does not need to take off the VR glasses immediately. Since the upper surface of the VR glasses body 1 near the strap 11 is threadedly connected with a rotating rod 41, the lower end of the rotating rod 41 extends through and extends to the upper side of the built-in partition 12 near the strap 11, and the lower end of the rotating rod 41 near the built-in partition 12 is fixedly connected with a magnetic ball 42, the user can rotate the rotating rod 41 to cause the magnetic ball 42 to move downward until it contacts the positioning support plate 4201. At this time, due to the protective plate 45 A magnetic ball 46 is fixedly connected, and the magnetism of the magnetic ball 46 is opposite to that of the magnetic ball 1 42. When the magnetic ball 42 moves downward to contact the upper surface of the positioning support plate 4201, it is on the same horizontal line with the magnetic ball 46. Therefore, after the magnetic ball 42 moves downward, the magnetic ball 46 can be driven to move horizontally toward each other by the magnetic attraction of the opposite magnetism to the magnetic ball 46, so that the protective plate 45 with the surface of eye protection green horizontally blocks the side of the VR lens 17 close to the strap 11;

[0094] Before the user needs to use the VR glasses next time, the user can first rotate the rotating rod 41 in the opposite direction to cause the magnetic ball 1 42 to move up. As the magnetic ball 1 42 moves up, the surfaces of the magnetic sliders 44 that are close to each other are magnetic and have the same magnetism. The repulsive force between the magnetic sliders 44 with the same magnetism is smaller than the magnetic attraction force of the opposite magnetism between the magnetic ball 2 46 and the magnetic ball 1 42. Therefore, when the magnetic ball 1 42 moves down and is on the same horizontal line with the magnetic ball 2 46, the magnetic ball 2 46 and the guard plate 45 can be moved towards each other, and the guard plate 45 remains relatively still. When the user manually rotates the rotating rod 41 to cause the magnetic ball 1 42 to move up and reset, no magnetic attraction is generated between the magnetic ball 2 46 and the magnetic ball 1 42. Therefore, under the repulsive force of the same magnetism between the magnetic sliders 44, the guard plate 45 can slide in the opposite direction and reset, so that the user can continue to use the VR glasses next time.

[0095] This embodiment has the following effects compared to the prior art:

[0096] After the user finishes using the VR glasses, without removing the glasses, the user can relieve eye fatigue after watching the VR glasses and avoid eye discomfort after using the VR glasses. By watching the green protective plate 45, the user's eye damage after using the VR glasses can be reduced.

[0097] At the same time, due to the horizontal displacement of the second magnetic ball 46 towards each other, the guard plate 45 horizontally blocks the side of the VR lens 17 close to the strap 11, so that after the user finishes using the VR glasses, the VR lens 17 is immediately shielded and protected, thereby preventing external dust or impurities from falling on the surface of the VR lens 17, and preventing the user from accidentally scratching the surface of the VR lens 17, thereby reducing the damage of the VR lens 17 and ensuring the clarity of the VR glasses when the user uses them later.

[0098] Finally, after the user takes off the VR glasses, the user can manually slide the protective cover 21 in the opposite direction to reset it to the initial state to protect the shift dial button 24 and avoid the original pupil distance being changed due to the user accidentally touching the shift dial button 24 when the VR glasses are not in use.

[0099] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
