Description
Technical Field
[0001] The utility model relates to an AR glasses, in particular to an AR glasses shaft device with excessive bending protection. Background Art
[0002] As AR glasses have evolved from theoretical technology to the research and development of real products, the demand for AR glasses is becoming more and more widespread, and the types and uses of AR glasses are increasing. The application potential of AR augmented reality is quite huge. It can be widely used in many fields such as medicine, manufacturing and maintenance, and entertainment.
[0003] Most AR glasses in the prior art are large in size and heavy in weight, which affects the wearing comfort, convenience and flexibility of the user; at the same time, the temples of AR glasses in the prior art cannot be folded back, which takes up a large space when stored and is easy to be damaged. Since the temples of AR glasses in the prior art are fixedly installed and the distance between the two temples is fixed, users with larger or smaller head circumferences cannot match the glasses, which further affects the wearing comfort and user experience of AR glasses. Summary of the invention
[0004] The purpose of the utility model is to provide an AR glasses hinge device with excessive bending protection, which can enable the temples of the AR glasses to rotate flexibly, facilitate the storage and carrying of the AR glasses, and at the same time provide a comfortable wearing and using experience for users with different head circumferences.
[0005] The utility model is achieved in this way:
[0006] A pivot device for AR glasses with excessive bending protection comprises a pivot forearm, a rotating member, a pivot middle arm, a pivot rear arm and a fixing member; a fixing plate is formed at the front of the pivot forearm, so that the pivot forearm is fixedly mounted on the AR glasses body through the fixing plate; a first slot is formed at the rear of the pivot forearm, and the front of the pivot middle arm is correspondingly inserted into the first slot, and rotating holes are formed on the rear of the pivot forearm and the front of the pivot middle arm, so that the pivot forearm is rotatably connected to the pivot middle arm through the rotating member and the rotating hole; a second slot is formed in the pivot rear arm, and the rear of the pivot middle arm is inserted into the second slot from front to back, and one end of the fixing member is inserted into the second slot from back to front and fixedly connected to the rear of the pivot middle arm; a temple mounting portion is formed at the rear of the pivot rear arm, and the temple is fixedly connected to the temple mounting portion.
[0007] A first limiting surface is formed at the rear end of the front arm of the rotating shaft, and a second limiting surface is formed at the front end of the rear arm of the rotating shaft; the first limiting surface is a convex arc surface structure, and the arc surface structure circumferentially surrounds the outside of the rotating hole, and the second limiting surface is a concave L-shaped surface structure, so that the first limiting surface can be rotatably embedded in the second limiting surface.
[0008] A first limiting protrusion is formed at the outer end of the first limiting surface, and a second limiting protrusion is formed at the outer end of the second limiting surface. When the first limiting surface is embedded in the second limiting surface, a gap is left between the second limiting protrusion and the first limiting protrusion, so that the rear arm of the rotating shaft can be flipped outward relative to the front arm of the rotating shaft through the rotating part until the second limiting protrusion abuts against the first limiting protrusion.
[0009] The fixing member is sleeved with a compression spring, and the two ends of the compression spring are respectively abutted between the other end of the fixing member and the rear end surface of the rear arm of the rotating shaft, so that the rear arm of the rotating shaft can be pressed against the front arm of the rotating shaft.
[0010] There are two rotating members, and two plug-in boards are formed at the front part of the middle arm of the rotating shaft, so that the two plug-in boards are rotatably plugged into the top and bottom of the first slot through the two rotating members respectively.
[0011] There are two fixing members, two plug-in screw barrels are formed on the rear part of the middle arm of the rotating shaft, and two mounting blocks with second slots are formed on the rear arm of the rotating shaft. The two plug-in screw barrels are respectively inserted into the second slots of the two mounting blocks, and the two fixing members are respectively inserted into the second slots of the two mounting blocks, so that the plug-in screw barrels are screwed and fixed to the fixing members.
[0012] The fixing plates are provided with two pieces, and the two fixing plates are staggered and vertically arranged.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The utility model is provided with a rotating shaft forearm, a rotating shaft middle arm and a rotating shaft rear arm. The rotating shaft rear arm rotates relative to the rotating shaft forearm through the rotating shaft middle arm via a rotating member, so that the temples can be folded inwardly relative to the AR glasses body, thereby reducing the volume of the AR glasses. The temples can be opened and closed flexibly and smoothly, which is convenient for carrying and storage, thereby improving the practicality of the AR glasses.
[0015] 2. In the present invention, since the first limiting surface and the second limiting surface are provided, the first limiting surface of the arc surface structure can rotate relative to the second limiting surface of the L-shaped surface structure through the rotating member, thereby ensuring the flexible rotation of the rear arm of the rotating shaft relative to the front arm of the rotating shaft and realizing the opening and closing function of the temples; at the same time, the first limiting protrusion and the second limiting protrusion at the outer end limit the amplitude of the outward reverse flipping of the rear arm of the rotating shaft, thereby avoiding excessive outward bending and flipping of the temples, and protecting the safety of the temples and the rotating member.
[0016] 3. Since the utility model is provided with a compression spring, the compression degree of the compression spring can be adjusted by screwing in and out the fixing piece and the plug-in screw barrel, so that the reaction force of the compression spring is used to press the rear arm of the rotating shaft onto the front arm of the rotating shaft, so that the first limiting surface and the second limiting surface are pressed and fitted, and the front arm of the rotating shaft and the rear arm of the rotating shaft form a stable fit, which neither affects the rotation of the temple driven by the rear arm of the rotating shaft nor ensures that the temple can be stably clamped on the user's head and the temple can be stably folded inward for storage.

DETAILED DESCRIPTION
[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Please see attached Figure 1 To Attachment Figure 5, an AR glasses hinge device with excessive bending protection, comprising a hinge forearm 1, a rotating member 2, a hinge middle arm 3, a hinge rear arm 4 and a fixing member 6; a fixing plate 11 is formed at the front of the hinge forearm 1, so that the hinge forearm 1 is fixedly mounted on the AR glasses body 7 through the fixing plate 11 by screws; a first slot 12 is formed at the rear of the hinge forearm 1, and the front of the hinge middle arm 3 is correspondingly inserted into the first slot 12, and a rotating hole 8 is formed on the rear of the hinge forearm 1 and the front of the hinge middle arm 3, so that the hinge forearm 1 is rotatably connected to the hinge middle arm 3 through the rotating member 2 through the rotating hole 8; a second slot (not shown in the figure) is formed in the hinge rear arm 4, and the rear of the hinge middle arm 3 is inserted into the second slot from front to back, and one end of the fixing member 6 is inserted into the second slot from back to front and fixedly connected to the rear of the hinge middle arm 3; a temple mounting portion 41 is formed at the rear of the hinge rear arm 4, and the temple 9 is fixedly connected to the temple mounting portion 41 by screws. The rear arm 4 and the middle arm 3 of the rotating shaft can be rotated relative to the front arm 1 of the rotating shaft through the rotating member 2, so as to realize the folding of the temple 9 relative to the AR glasses body 7, which is convenient for reducing the volume of the AR glasses and making them easy to store and carry. Preferably, the rotating member 2 can be a rotating shaft, and a limiting flange should be appropriately provided at the end of the rotating shaft to prevent the rotating shaft from falling out; the fixing member 6 can be a screw.
[0025] The rear end of the rotating shaft front arm 1 is formed with a first limiting surface 13, and the front end of the rotating shaft rear arm 4 is formed with a second limiting surface 42; the first limiting surface 13 is a convex arc surface structure, and the arc surface structure circumferentially surrounds the outer side of the rotating hole 8, and the second limiting surface 42 is a concave L-shaped surface structure, so that the first limiting surface 13 can be rotatably embedded in the second limiting surface 42. The first limiting surface 13 of the arc surface structure can rotate relative to the second limiting surface 42 through the rotating member 2, which can ensure the flexible rotation of the rotating shaft rear arm 4 relative to the rotating shaft front arm 1, thereby ensuring that the temple 9 can be folded inward by 90°, which is convenient for inward folding and storage.
[0026] The first limiting surface 13 is formed with a first limiting protrusion 14 at the outer end (the end close to the user's face is the inner end, and the end away from the user's face is the outer end), and the second limiting protrusion 43 is formed at the outer end of the second limiting surface 42. When the first limiting surface 13 is embedded in the second limiting surface 42, a gap is left between the second limiting protrusion 43 and the first limiting protrusion 14, so that the rear arm 4 of the rotating shaft can be turned outward relative to the front arm 1 of the rotating shaft through the rotating member 2 until the second limiting protrusion 43 abuts against the first limiting protrusion 1. When the AR glasses are worn on the head of a user with a large head circumference, the two temples 9 will be turned outward. Since there is a gap between the second limiting protrusion 43 and the first limiting protrusion 14, a certain space is left for the eversion of the temple 9 to prevent the temple 9 from being damaged by hard folding. The width of the gap between the second limiting protrusion 43 and the first limiting protrusion 14 can be adjusted according to the eversion angle range of the temple 9, preferably, the temple 9 can be turned outward by about 17°.
[0027] The fixing member 6 is sleeved with a compression spring 5, and the two ends of the compression spring 5 are respectively abutted between the other end of the fixing member 6 and the rear end surface of the rotating shaft rear arm 4, so that the rotating shaft rear arm 4 can be pressed against the rotating shaft front arm 1. The fixing member 6 and the rotating shaft rear arm 4 put the compression spring 5 in a compressed state, so that the rotating shaft rear arm 4 is pressed against the rotating shaft front arm 1 by the reaction force of the compression spring 5, so that the first limiting surface 13 and the second limiting surface 42 are pressed and fitted, and the rotating shaft front arm 1 and the rotating shaft rear arm 4 form a stable fit, which is convenient for locking the flip angle of the temple 9, preventing the temple 9 from loosening and causing the AR glasses to fall off, and also preventing the inwardly folded temple 9 from accidentally opening.
[0028] There are two rotating members 2, and two plug-in plates 31 are formed at the front of the rotating shaft middle arm 3, so that the two plug-in plates 31 are rotatably plugged into the top and bottom of the first slot 12 through the two rotating members 2. The symmetrical arrangement of the two rotating members 2 and the two plug-in plates 31 can improve the rotation stability between the rotating middle arm 3 and the rotating forearm 1, thereby ensuring the stable flipping of the temple 9.
[0029] The fixing members 6 are provided with two, and two plug-in screw barrels 32 are formed at the rear of the middle arm 3 of the rotating shaft, and two mounting blocks 44 with second slots are formed on the rear arm 4 of the rotating shaft. The two plug-in screw barrels 32 are respectively inserted into the second slots of the two mounting blocks 44, and the two fixing members 6 are respectively inserted into the second slots of the two mounting blocks 44, so that the plug-in screw barrels 32 and the fixing members 6 are screwed and fixed. The symmetrical arrangement of the two fixing members 6, the two mounting blocks 44 and the two plug-in screw barrels 32 can improve the connection stability between the rotating middle arm 3 and the rotating rear arm 4, thereby ensuring the stable installation and clamping of the temple 9. Preferably, a cavity can be reserved at one end of the temple 9 connected to the rear arm 4 of the rotating shaft, so as to facilitate the insertion of the hidden fixing member 6 and the compression spring 5, thereby improving the aesthetics of the AR glasses.
[0030] The fixing plates 11 are provided with two pieces, and the two fixing plates 11 are staggered and vertically arranged. The two fixing plates 11 can be fixed on the outer shell of the AR glasses body 7 by screws. The two vertically arranged fixing plates 11 can improve the connection reliability between the temples 9 and the AR glasses body 7.
[0031] Please see attached Figure 1 To Attachment Figure 5 , the working principle of the utility model is:
[0032] When the two temples 9 are opened, the user can wear the AR glasses body 7 on the head through the two temples 9.
[0033] If the user's head circumference is small, the fixing part 6 can be rotated further into the plug-in screw barrel 32 to further compress the clamping spring 5, ensuring that the second limiting surface 42 of the rear arm 4 of the rotating shaft abuts the first limiting surface 13 of the front arm 1 of the rotating shaft, so that the two temples 9 can be rotated inwardly and closer to each other, and are clamped on the user's head under the abutment of the second limiting surface 42 and the first limiting surface 13.
[0034] If the user has a large head circumference, the two temples 9 are turned outward when wearing the glasses, so that the second limiting protrusion 43 rotates to abut against the first limiting protrusion 14, thereby protecting the rotating member 2 and the temples 9 and preventing the temples 9 from over-turning. At the same time, under the action of the pressing spring 5, the rear arm 4 of the rotating shaft is pressed against the front arm 1 of the rotating shaft, the rotation is stable, the temples 9 will not move, and the temples 9 are stably clamped on the head.
[0035] When not in use, the two temples 9 are flipped inward and closed, and the rear arm 4 of the rotating shaft rotates relative to the front arm 1 of the rotating shaft through the rotating member 2. Under the compression action of the compression spring 5, the closing stability of the two temples 9 is ensured and they will not open accidentally.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
