[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] Embodiment 1

[0038] like Figure 1-Figure 10 As shown, the present embodiment is a detachable AR glasses rotation self-locking device, including a fixed box 1, a card slot 11 is opened inside the fixed box 1, a self-locking component is arranged inside the fixed box 1, and the self-locking component includes a rotating shaft 21 rotatably connected to one end of the fixed box 1, a rotating ring 2 is fixedly connected to the circumferential surface of the rotating shaft 21, two auxiliary rods 57 are slidably connected to the circumferential surface of the rotating shaft 21, a compression spring is fixed between the two auxiliary rods 57, and a third compression spring 58 is sleeved on the circumferential surface of the rotating shaft 21, and unlocking components are arranged at both ends of the rotating shaft 21, and the unlocking components are used to control the card block 12.

[0039] Specifically, in the process of using the existing head-mounted AR glasses, because the head-mounted AR glasses are relatively heavy, inconvenient to carry and store, and cannot be disassembled, the head-mounted AR glasses will take up a large space when stored when used outdoors, and because the lenses of the head-mounted AR glasses are relatively large, the head-mounted AR glasses can only be placed horizontally. If placed vertically, the head-mounted AR glasses are easily tipped over, and the head-mounted AR glasses will be broken, resulting in the problem that the lenses of the head-mounted AR glasses are difficult to protect when used outdoors;

[0040] Therefore, the present invention fixes the head-mounted AR glasses by setting a certain structure, and can adjust them at the same time; first, the AR glasses lens needs to be installed in the fixing box 1, and the unlocking component is pressed to push the two auxiliary rods 57 through the unlocking component, and the two auxiliary rods 57 move toward each other, and then the two auxiliary rods 57 will push the two card blocks 12 on the side close to each other to slide toward each other along the rotating shaft 21, and the two sliding card blocks 12 will squeeze the third compression spring 58, and then the two card blocks 12 will be separated from the card slot 11 of the fixing box 1, and then the fixing box 1 is inserted into the AR glasses frame, and then the push on the auxiliary rod 57 is released, and the two card blocks 12 are engaged with the AR glasses frame from the inside, so as to achieve the connection with the AR glasses lens, and then the fixing box 1 is engaged with the head ring, and the AR glasses lens can be flipped for use, which is more convenient. After use, by pressing the unlocking component in the same way, the AR glasses frame is disassembled, so that the AR glasses lens can be protected separately, and there is no need to solve the problem that the AR glasses lens cannot be effectively protected because the head-mounted AR glasses device is too large;

[0041] The problem that the head-mounted AR glasses can only be placed horizontally due to their large lenses is solved. If they are placed vertically, the head-mounted AR glasses are likely to topple over and break, resulting in the problem that the lenses of the head-mounted AR glasses are difficult to protect when used outdoors is solved.

[0042] like Figure 4 As shown, the unlocking assembly of this embodiment includes connecting blocks 3 rotatably arranged at both ends of the rotating shaft 21, and a through groove is opened on one side of each connecting block 3. A push rod 54 is slidably connected in the through groove, and the push rod 54 is fixedly connected to the auxiliary rod 57. The end of the push rod 54 away from the auxiliary rod 57 is rotatably connected to the positioning rod 51, and one end of the positioning rod 51 is fixedly connected to the positioning plate 5.

[0043] Specifically, when the unlocking component is used, the unlocking component is arranged on two connecting blocks 3 at both ends of the rotating shaft 21, and the connecting blocks 3 can be clamped on the head ring, and then when clamping the AR glasses frame, the positioning plate 5 is pushed, and the positioning plate 5 pushes the positioning rod 51, and then the positioning rod 51 will push the push rod 54, thereby pushing the auxiliary rod 57, and then the auxiliary rod 57 will push the clamping block 12 to slide inward, and then the fixing box 1 is inserted into the AR glasses frame and the positioning plate 5 is released. The clamping block 12 is rebounded by the third compression spring 58, thereby clamping the AR glasses frame, and realizing the fixing of the AR glasses lens, and then clamping with the AR glasses head ring through the connecting block 3, the AR glasses lens and the head ring can be assembled, achieving the effect of convenient disassembly, and facilitating the disassembly and protection of the AR glasses lens.

[0044] like Figure 5 As shown, one end of the push rod 54 of this embodiment is fixedly connected to a fixed tube 53, and the end of the positioning rod 51 corresponding to the push rod 54 is fixedly connected to two connecting rods 52. The connecting rod 52 and the fixed tube 53 are penetrated by the same plug shaft 55, and the circumferential surface of the plug shaft 55 is sleeved with a torsion spring 56. The unlocking component also includes a clamping piece arranged on one side of the connecting block 3, and the clamping piece is used to clamp the positioning rod 51.

[0045] Specifically, the auxiliary rod 57 is pushed to drive the card block 12 so that the fixing box 1 is inserted into the frame of the AR glasses. Then, in order to prevent the positioning rod 51 and the positioning plate 5 from affecting the user's operating rod during use, the insertion shaft 55 between the positioning rod 51 and the auxiliary rod 57 is rotated, and then the positioning rod 51 can be rotated and connected into the card connector, thereby achieving a storage effect and preventing the positioning rod 51 from interfering with the user's line of sight.

[0046] like Figure 6 As shown, the clamping member of this embodiment includes a fixed frame 4 fixedly connected to one side of each connecting block 3, and a limiting member is arranged on the side of the fixed frame 4 close to the connecting block 3. The limiting member includes a first groove body 41 opened in the fixed frame 4, and two limiting plates 43 are elastically arranged in the first groove body 41. The same end of the two limiting plates 43 is fixed with a hook plate 45, and the hook plate 45 is used to limit the positioning rod 51.

[0047] Specifically, after the positioning rod 51 is rotated, the positioning rod 51 can be inserted into the two limit plates 43 for clamping. The two limit plates 43 are elastically arranged in the first groove 41 of the fixed frame 4. At the same time, a hook plate 45 is fixedly connected to the same end of the two limit plates 43. The positioning rod 51 clamped into the limit plate 43 is limited by the hook plate 45. Figure 3 As shown, the longer positioning rod 51 can be folded and stored, achieving the effect of convenient use.

[0048] like Figure 6As shown, the limiting member of this embodiment further includes first compression springs 44 fixedly connected to the upper and lower inner walls of the first slot body 41 , and one end of each first compression spring 44 away from the inner wall of the first slot body 41 is fixedly connected to the limiting plate 43 .

[0049] Specifically, first compression springs 44 are fixedly connected to the upper and lower inner walls of the first groove body 41, and then one end of each first compression spring 44 away from the inner wall of the first groove body 41 is fixedly connected to the limiting plate 43, so that when the positioning rod 51 squeezes the hook plate 45 to enter the limiting plate 43, the first compression spring 44 can perform elastic expansion and contraction, and then the positioning rod 51 is hooked and clamped by the hook plate 45, thereby achieving the folding and storage effect of the positioning rod 51.

[0050] like Figure 6 As shown, a telescopic rod 42 is provided in the middle of the first compression spring 44 of this embodiment, the top end of the telescopic rod 42 is fixedly connected to the top wall of the first slot body 41 , and the bottom end of the telescopic rod 42 is fixedly connected to the limiting plate 43 .

[0051] Specifically, by providing a telescopic rod 42 in the middle of the first compression spring 44 , the first compression spring 44 can be limited, thereby preventing the first compression spring 44 from being deformed laterally.

[0052] like Figure 6 and Figure 7 As shown, in this embodiment, a second slot body 46 is opened on the side of the fixed frame 4 away from the first slot body 41, a second compression spring 49 is fixedly connected to one side of the second slot body 46, and a push plate 48 is fixedly connected to the end of the second compression spring 49 away from the fixed frame 4. The cross-section of the push plate 48 is convex, and a fixing rod 47 is fixedly connected to one side of the push plate 48.

[0053] Specifically, a second slot 46 is provided on one side of the fixing frame 4. After the positioning rod 51 is inserted into the two limiting plates 43, the fixing rod 47 in the second slot 46 is pushed by pressing. After the fixing rod 47 is pushed, it slides along the second slot 46, and then the second compression spring 49 is compressed. After the second compression spring 49 is compressed, the push plate 48 can be inserted between the two limiting plates 43. Figure 6 and Figure 7 As shown, the effect of propping up the two limit plates 43 is achieved. After the two limit plates 43 are propped up, the positioning rod 51 can be released, and the positioning rod 51 will be reset under the action of the torsion spring 56, achieving a better use effect of the positioning rod 51, which is more convenient and quick.

[0054] The working method of the detachable AR glasses rotation self-locking device is as follows:

[0055] Combination: The AR glasses’ lenses and headband are fixed by rotating the self-locking structure of the AR glasses;

[0056] Release the unlocking assembly: by pressing the fixing rod 47, the push plate 48 is pushed to slide along the second groove 46, and the push plate 48 is inserted between the two limit plates 43. Since the cross section of the push plate 48 is convex, the two limit plates 43 that slide elastically up and down can be pushed open, and then the positioning rod 51 returns to a coaxial state with the push rod 54 under the action of the torsion spring 56;

[0057] Unlock the self-locking component: By pushing the positioning plates 5 on both sides of the fixing box 1, the two positioning plates 5 will drive their respective rotationally connected push rods 54, and then the two push rods 54 will push the auxiliary rods 57 on both sides, and the two auxiliary rods 57 will squeeze the third compression spring 58 inward, so that the card block 12 is disengaged from the card slot 11 of the fixing box 1, and the fixing box of the fixing box 1 and the AR glasses can be unlocked, so that the lenses of the AR glasses can be removed.

[0058] Embodiment 2

[0059] like Figures 2 to 10 As shown, compared with Example 1, another implementation of the present invention is: a storage box 6 is fixedly connected to the upper surface of the fixed box 1, a first cavity 61 is opened in the storage box 6, and the first cavity 61 stores lubricating oil, two limit blocks 66 are fixedly connected to one side of each auxiliary rod 57, and a limit shaft 67 is fixedly connected between the two limit blocks 66, a buckle plate 62 is rotatably connected to the circumferential surface of one limit shaft 67, and a buckle groove plate 64 is rotatably connected to the circumferential surface of the other limit shaft 67, and the buckle groove plate 64 can be inserted into the buckle plate 62, the bottom wall of the storage box 6 and the upper surface of the fixed box 1 are opened with fixing holes 63, and the upper surfaces of the buckle plate 62 and the buckle groove plate 64 are also opened with fixing holes 63, and the position of the inner wall of the fixed box 1 corresponding to the fixing hole 63 is fixed with an auxiliary block 65, and the auxiliary block 65 is used to disperse the lubricating oil.

[0060] Specifically, after the AR glasses' rotating self-locking structure has been used for a long time, the internal rotating shaft 21 may be stuck due to corrosion. At this time, the entire fixing box 1 is turned over so that the storage box 6 faces upward, as shown in the attached figure. Figure 2 As shown, the positioning rods 51 on both sides are pushed, and the positioning rods 51 will push the auxiliary rods 57 on both sides to move toward each other. The movement of the auxiliary rods 57 toward each other can drive and rotate the buckle plate 62 set on one of the auxiliary plates, and then the buckle groove plate 64 on one side of the other auxiliary plate will be inserted into the buckle plate 62. Figure 8As shown, when the card block 12 is disengaged from the card slot 11, the center of the circle of the fixing hole 63 on the buckle plate 62 and the buckle slot plate 64 is aligned, and at the same time, the fixing hole 63 on the bottom wall of the fixed box 1 and the storage box 6 is also aligned with the center of the circle of the fixing frame 4 on the buckle plate 62 and the buckle slot plate 64, so that the lubricating oil in the storage box 6 will flow into the auxiliary block 65, and then the auxiliary block 65 disperses the lubricating oil flowing into the auxiliary block 65 and drips it onto the rotating shaft 21, which has a lubricating effect. However, in the process of using the AR glasses' rotating self-locking structure, since the storage box 6 is inverted, the lubricating oil cannot flow out, and the only way is to invert the AR glasses' rotating self-locking structure and drip the lubricating oil separately, thereby achieving convenient maintenance of the AR glasses' rotating self-locking structure and improving the use effect.

[0061] like Fig. 9 As shown, in this embodiment, a positioning groove 610 is formed on the inner wall of the auxiliary block 65 , a cone block 68 is fixedly connected in the positioning groove 610 , and a plurality of positioning holes 69 are formed on the cone surface of the cone block 68 .

[0062] Specifically, a cone block 68 is fixedly connected to the auxiliary block 65, as shown in the attached Fig. 9 As shown, with the setting of the cone block 68, when the lubricating oil flows into the auxiliary block 65, the lubricating oil will slide down along the inclined surface of the cone block 68. During the sliding process, it will flow into each positioning hole 69, and then flow onto the rotating shaft 21, thereby achieving better dripping of the lubricating oil on the rotating shaft 21 and improving the maintenance quality.

[0063] Working principle: first, the AR glasses lens needs to be installed in the fixing box 1, and the positioning plate 5 is pushed by pressing the unlocking component, and the positioning plate 5 is pushed by the positioning plate 5. Then the positioning rod 51 will push the push rod 54, thereby pushing the auxiliary rod 57, and then the auxiliary rod 57 will push the clamping block 12 to slide inward, and then the fixing box 1 is inserted into the AR glasses frame and the positioning plate 5 is released. The clamping block 12 is rebounded by the third compression spring 58, thereby clamping the AR glasses frame to achieve the fixed connection of the AR glasses lens, and then the AR glasses head ring is clamped by the connecting block 3 to realize the assembly of the AR glasses lens and the head ring, achieving the effect of convenient disassembly, which is convenient for the disassembly and protection of the AR glasses lens, and then the fixing box 1 is clamped on the head ring, and the AR glasses lens can be turned over for use, which is more convenient. After use, by pressing the unlocking component in the same way, the AR glasses frame is disassembled, which is convenient for the AR glasses lens to be protected separately, and there is no need to solve the problem that the AR glasses lens cannot be effectively protected because the head-mounted AR glasses device is too large;

[0064] Then, in order to prevent the positioning rod 51 and the positioning plate 5 from affecting the user's operating rod during use, the insertion shaft 55 between the positioning rod 51 and the auxiliary rod 57 is rotated. After the positioning rod 51 is rotated, the positioning rod 51 can be inserted into the two limit plates 43 for clamping. The two limit plates 43 are elastically arranged in the first groove body 41 of the fixed frame 4. At the same time, a hook plate 45 is fixedly connected to the same end of the two limit plates 43. The positioning rod 51 clamped in the limit plate 43 is limited by the hook plate 45. Figure 3 As shown, the longer positioning rod 51 can be folded and stored, achieving the effect of convenient use and preventing the positioning rod 51 from interfering with the user's sight;

[0065] In addition, a second groove 46 is provided on one side of the fixing frame 4. After the positioning rod 51 is inserted into the two limiting plates 43, the fixing rod 47 in the second groove 46 is pushed by pressing. After the fixing rod 47 is pushed, it slides along the second groove 46, and then the second compression spring 49 is compressed. After the second compression spring 49 is compressed, the push plate 48 can be inserted between the two limiting plates 43. Figure 6 and Figure 7 As shown, the effect of propping up the two limit plates 43 is achieved. After the two limit plates 43 are propped up, the positioning rod 51 can be released, and the positioning rod 51 will be reset under the action of the torsion spring 56, achieving a better use effect of the positioning rod 51, which is more convenient and quick;

[0066] Finally, after the AR glasses' rotating self-locking structure has been used for a long time, the internal rotating shaft 21 may be stuck due to corrosion. At this time, the entire fixing box 1 is turned over so that the storage box 6 faces upward, as shown in the attached figure. Figure 2 As shown, the positioning rods 51 on both sides are pushed, and the positioning rods 51 will push the auxiliary rods 57 on both sides to move toward each other. The movement of the auxiliary rods 57 toward each other can drive and rotate the buckle plate 62 set on one of the auxiliary plates, and then the buckle groove plate 64 on one side of the other auxiliary plate will be inserted into the buckle plate 62. Figure 8 As shown, when the block 12 is separated from the slot 11, the fixing holes 63 on the buckle plate 62 and the buckle slot plate 64 are aligned with the center of the circle, and the fixing holes 63 on the bottom wall of the fixed box 1 and the storage box 6 are also aligned with the center of the circle of the fixed frame 4 on the buckle plate 62 and the buckle slot plate 64, so that the lubricating oil in the storage box 6 will flow into the auxiliary block 65, and the cone block 68 is fixed in the auxiliary block 65, as shown in the attached figure. Fig. 9As shown, with the arrangement of the cone block 68, after the lubricating oil flows into the auxiliary block 65, the lubricating oil will slide down along the inclined surface of the cone block 68, and in the process of sliding down, it will flow into each positioning hole 69, and then flow to the rotating shaft 21, so as to achieve better dripping of the lubricating oil on the rotating shaft 21, improve the maintenance quality, and achieve the lubrication effect. However, in the process of using the AR glasses' rotating self-locking structure, since the storage box 6 is inverted, the lubricating oil cannot flow out, and the lubricating oil can only be dripped separately by inverting the AR glasses' rotating self-locking structure, thereby achieving convenient maintenance of the AR glasses' rotating self-locking structure and improving the use effect.
