DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figure 1 As shown, an open augmented reality device of the present invention includes a frame 1 and support members 2 installed on both sides of the frame 1, the support member 2 includes a first support portion 21 and a second support portion 22, and a fixing assembly is provided on the first support portion 21, and the fixing assembly includes an upper plate 31 and a lower plate 32, and the upper plate 31 and the lower plate 32 are respectively provided at the upper and lower ends of the first support portion 21, and a rotating shaft is fixedly installed at one end of the lower plate 32, and the rotating shaft passes through the first support portion 21 and is fixedly connected to the upper plate 31. By providing the rotating shaft, the fixing assembly can rotate relative to the first support portion 21.

[0033] like Figure 2 and Figure 3 As shown, the upper plate 31 has a through hole at one end away from the rotating shaft, into which a limiting rod 4 is slidably inserted. The lower plate 32 has a limiting hole 321, into which the lower end of the limiting rod 4 is inserted. After the fixing assembly is rotated out of the first support portion 21, a fixed area is formed between the upper plate 31, the lower plate 32, the first support portion 21, and the limiting rod 4. During use, the two supporting legs 51 of the ordinary glasses 5 can be placed in the fixed area on both sides of the AR glasses and fixed, so that the AR glasses can be fixedly hung on the ordinary glasses 5, allowing the user to wear both the ordinary glasses 5 and the AR glasses at the same time. In this embodiment, the AR glasses are used as a replacement for the ordinary glasses 5, that is, the two AR glasses are fixed together.

[0034] A limiting through hole 211 is provided on the first support portion 21, and the limiting rod 4 passes through the limiting through hole 211 and is inserted into the limiting hole 321, so that the limiting rod 4 passes through the support member 2 and is inserted into the lower plate body 32; by setting the limiting through hole 211, when the fixing component is not in use, the limiting rod 4 can be inserted into the limiting through hole 211 to prevent the limiting rod 4 from moving at will. At the same time, the fixing component is stored to avoid affecting the use of AR glasses by the experiencer who is not wearing ordinary glasses 5.

[0035] like Figure 2 As shown, a limit plate 41 is provided at one end of the limit rod 4 near the lower plate 32. A first spring 42 is sleeved on the limit rod 4. One end of the first spring 42 is fixedly connected to the limit plate 41, and the other end is fixedly connected to the surface of the lower plate 32. By providing the limit plate 41 and the first spring 42, the first spring 42 is normally in a stretched state, preventing the limit rod 4 from falling off the lower plate 32. The lower plate 32 is provided with a sleeve 323 at the limit rod 4. The sleeve 323 covers the outside of the first spring 42 to prevent debris from getting stuck in the first spring 42 and affecting the service life of the first spring 42.

[0036] like Figure 4 As shown, a torsion spring is provided between the rotating shaft and the support member 2; when the fixing assembly is screwed out of the first support portion 21, the torsion spring is compressed, causing it to deform; after the support leg 51 of the ordinary glasses 5 is inserted into the fixing area, the torsion spring resets the fixing assembly until the limit rod 4 contacts the inner side of the support leg 51 of the ordinary glasses 5. The limit rods 4 on both sides respectively spread the support legs 51 to the sides, thereby pressing the support legs 51 toward the first support portion 21, preventing the support legs 51 from moving relative to the first support portion 21. In this embodiment, a friction sleeve is provided on the outer surface of the limit rod 4, preferably a rubber sleeve with strong friction properties, which increases the friction between the limit rod 4 and the support leg 51 of the ordinary glasses 5, preventing the ordinary glasses 5 from sliding freely.

[0037] like Figure 3As shown, elastic blocks 11 are provided at both ends of the inner side of the frame 1; by providing the elastic blocks 11, the ordinary glasses 5 are prevented from directly fitting with the AR glasses, thereby preventing the lenses from being scratched; at the same time, they can cooperate with the fixing components to clamp the ordinary glasses 5 to prevent the ordinary glasses 5 from loosening.

[0038] like Figure 2 As shown, an expansion assembly is provided between the support member 2 and the frame 1. The expansion assembly includes a connecting block 6. A mounting groove 12 is provided on both sides of the frame 1. One end of the connecting block 6 is rotatably connected to the mounting groove 12, allowing the connecting block 6 to rotate within the mounting groove 12. When in use, the connecting block 6 is extended outward so that the ordinary glasses 5 can be placed between the two support members 2 of the AR glasses. Limiting members 121 are installed at the upper and lower ends of the mounting groove 12 on one side of the connecting block 6. The limiting members 121 are connected to the side of the connecting block 6. By providing the limiting members 121, the connecting block 6 is limited to prevent the connecting block 6 from rotating freely. The limiting member 121 is a ball plunger. The bottom of the ball plunger is fixedly connected to the inner wall of the mounting groove 12. The upper and lower ends of the connecting block 6 are provided with an arc groove 61 at the bottom of the ball plunger. The end of the ball plunger is connected to the side of the connecting block 6. By providing the ball plunger, the connecting block 6 can be effectively prevented from rotating freely and the position of the connecting block 6 can be easily adjusted.

[0039] The first support part 21 is rotatably connected to the connecting block 6. A first limit block 212 is provided at the end of the first support part 21 near the connecting block 6. By providing the first limit block 212, the maximum rotation angle of the first support part 21 relative to the connecting block 6 is 90°, so that the user can wear it.

[0040] like Figure 2 and Figure 4 As shown, the second support portion 22 is rotatably connected to the free end of the first support portion 21, and a second limiting block 221 is provided on the second support portion 22 near the end of the first support portion 21. By providing the second limiting block 221, the angle of rotation of the second support portion 22 relative to the first support portion 21 is limited, so that the user can wear the support member 2 easily. A receiving groove 213 is provided at the bottom of the first support portion 21, and an adsorption block 222 is provided at the bottom of the free end of the second support portion 22. In this embodiment, the adsorption block 222 is an iron block, and a magnetic sheet is provided in the receiving groove 213. When the AR glasses need to be fixed on ordinary glasses 5, the second support portion 22 can be screwed into the receiving groove 213 of the first support portion, and the second support portion 22 can be fixed in the receiving groove 213 by adsorption of the magnetic sheet and the iron block to prevent the second support portion 22 from affecting the user's wearing.

[0041] The open augmented reality device of the present invention is used by an experiencer wearing ordinary glasses 5. First, the connecting blocks 6 on both sides of the frame 1 are rotated. After the connecting blocks 6 squeeze the ball plungers, the connecting blocks 6 and the frame 1 are rotated from a vertical state to a horizontal state. The ball plungers continue to limit the connecting blocks 6 again to prevent the connecting blocks 6 from rotating at will; then, the limiting rod 4 is pulled downward to withdraw the limiting rod 4 from the limiting through hole 211, and then the lower plate 32 is rotated toward the inside of the first support portion 21, so that a fixed area is formed between the upper plate 31, the lower plate 32, the first support portion 21 and the limiting rod 4, and the support legs 51 of the ordinary glasses 5 are clamped in After the fixing area, release the limit rod 4, and the first spring 42 causes the limit rod 4 to automatically move up and insert into the through hole of the upper plate body 31, thereby limiting the support leg 51 within the fixed area. Then release the upper plate body 31, and the torsion spring restores its deformation, so that the upper plate body 31 and the lower plate body 32 are reset until the limit rod 4 is in contact with the inner side surface of the support leg 51 of the ordinary glasses 5; the same operation is used to clamp the two support legs 51 of the ordinary glasses 5 into the fixed area and tighten them by the limit rod 4; finally, screw the second support part 22 into the accommodating groove 213 of the first support, and fix the second support part 22 in the accommodating groove 213 by adsorption of the magnetic sheet and the iron block.

[0042] Example 2:

[0043] like Figure 5-Figure 8 The present invention provides an open augmented reality device, further comprising a base 7, on which the AR glasses are placed. The base 7 is provided with a driving assembly for adjusting the fixing assembly. The driving assembly comprises a mounting block 71 and a driving block 72. The mounting block 71 is fixedly mounted on the surface of the base 7. A slide groove 711 is provided on the mounting block 71. The driving block 72 is slidably arranged in the slide groove 711. A driving groove 721 is provided on the driving block 72. A first driving member is provided at one end of the driving groove 721, and a second driving member is provided at the other end. The first driving member comprises two guide rods. The guide bars 81 are respectively arranged on both sides of the driving groove 721, and the two guide bars 81 are inclined downward from the end close to the limit rod 4 to the end away from the limit rod 4. A limit groove 411 is provided on the limit plate 41, and the two guide bars 81 are matched with the limit groove 411; when the driving block 72 is pushed to move, the guide bar 81 is stuck in the limit groove 411, and the driving block 72 is continuously pushed. The limit rod 4 can be gradually moved downward through the guide bar 81 until the limit rod 4 is disengaged from the limit through hole 211, so that the fixed component can be rotated.

[0044] The second driving member includes a rack 82, which is fixedly arranged on one side of the driving groove 721. A gear 322 is fixedly arranged on the lower plate 32, and the gear 322 is arranged at one end of the rotating shaft. The gear 322 is coaxial with the rotating shaft, and the rack 82 and the gear 322 are arranged in coordination; when the driving block 72 is pushed to move, the rack 82 engages with the gear 322, and continuously pushes the driving block 72, which will drive the gear 322 to rotate, thereby realizing the rotation of the fixed component.

[0045] A slot 722 is provided on one side of the driving slot 721 between the guide bar 81 and the rack 82, and an arc-shaped slide groove 712 is provided on the mounting block 71. When the slot 722 moves to the limiting rod 4, the limiting rod 4 disengages from the limiting through hole 211, continuously pushing the driving block 72, driving the gear 322 to rotate, so that the limiting rod 4 enters the arc-shaped slide groove 712 from the slot 722, so that the fixing component can rotate smoothly.

[0046] Limiting rings 713 are provided on both sides of the arcuate slot 712. These two limiting rings 713 cooperate with the limiting rod 4. By providing the limiting rings 713, when the limiting rod 4 slides in the arcuate slot 712, the surfaces of the limiting rings 713 contact the upper surface of the limiting plate 41, limiting the limiting plate 41 and preventing the first spring 42 from causing the limiting rod 4 to move upward. A notch is provided on the end of the limiting ring 713 away from the notch 722. By providing the notch, when the fixing assembly rotates to the notch, the limiting ring 713 disengages from the limiting plate 41, allowing the first spring 42 to cause the limiting rod 4 to move upward, and the top of the limiting rod 4 is inserted into the through hole of the upper plate 31.

[0047] A baffle 723 is provided at each end of the driving block 72. A sliding hole 714 is provided on the side of the mounting block 71 away from the frame 1. A sliding rod 724 is provided between the two baffles 723. The sliding rod 724 slides through the sliding hole 714. A second spring 725 is sleeved on the end of the sliding rod 724 near the rack 82. One end of the second spring 725 is fixedly connected to the baffle 723, and the other end is fixedly connected to the side of the mounting block 71. The provision of the sliding rod 724 and the second spring 725 allows the driving block 72 to be slidably installed in the sliding groove 711. When the driving block 72 is pressed, the second spring 725 can automatically rebound the driving block 72.

[0048] A support column 73 is provided on the end of the base 7 away from the mounting block 71. A slot 731 is defined at the upper end of the support column 73. The hinged ends of the first support portion 21 and the second support portion 22 are received within the slot 731. The support column 73 supports the support member 2, making it easier to remove and place it. The slot 731 also limits the position of the support member 2, preventing it from being pushed and moved when the drive block 72 moves.

[0049] The base 7 is provided with a support base 74, and the frame 1 is clamped on the support base 74, and the support base 74 is used to support the frame 1; a shielding block 75 is provided on the side of the support base 74 away from the frame 1, and the shielding block 75 is used to shield the lens in the frame 1 to prevent dust from being adsorbed on the lens.

[0050] In an open augmented reality device of the present invention, when the support legs 51 of ordinary glasses 5 need to be fixed, the ordinary glasses 5 are placed in the AR glasses, the support legs 51 are placed on the mounting blocks 71, and then the driving blocks 72 on both sides are pushed by both hands to move toward the mounting blocks 71, and the guide bars 81 are stuck in the limiting grooves 411, and the driving blocks 72 are continuously pushed. The guide bars 81 make the limiting rod 4 gradually move downward until the limiting rod 4 is disengaged from the limiting through-hole 211; when the notch 722 moves to the limiting rod 4, the driving block 72 is continued to be pushed, and after the rack 82 is engaged with the gear 322, the gear 322 is driven to rotate, so that the limiting rod 4 enters the arc from the notch 722. When the cam 72 is in the unlocked position, the locking cam 713 is in the unlocked position, and the locking cam 714 is in the unlocked position, and the locking cam 715 is locked, so that the cam 72 can slide freely in the unlocked position.
