Description

Technical Field

[0001] This utility model relates to the field of hinge structures, specifically a hinge structure for AR glasses. Background Technology

[0002] Augmented Reality (AR) is a technology that calculates the position and angle of camera images in real time and adds corresponding images. The goal of this technology is to overlay the virtual world onto the real world on a screen and allow for interaction. Existing AR glasses typically have a hinge between the frame and the support, allowing the glasses to be folded and stored. This is widely used in AR glasses; for example, the support frame and temples of the glasses are movably connected, usually using a hinge to open or close for user convenience.

[0003] The existing AR glasses hinge structure generally uses screw fixing method (such as threaded connection or bolt locking). This traditional solution has the following key drawbacks in practical applications: The traditional solution requires completing the steps of hole alignment → screw pre-installation → tool tightening → secondary calibration in sequence. The installation of a single hinge takes about 3-5 minutes. AR glasses usually need to install two hinges symmetrically, which further prolongs the assembly cycle and makes the installation inefficient. In addition, it must rely on equipment such as screwdrivers and power tools for installation, which makes the installation inconvenient. Furthermore, because the screws are small, they are easy to fall out when using a screwdriver, which makes it even more inconvenient to install the hinge onto the base of the AR glasses. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a hinge structure for AR glasses, which can effectively solve the technical problem that the existing hinges are installed by screws, resulting in inconvenient installation and low installation efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a rotating shaft structure for AR glasses, including a shaft core, a fixed base and a rotatable rotating base. A retaining spring is provided at the bottom of the rotating base, and a bushing is provided at one end of the rotating base. The bushing has a shaft hole that matches the shaft core inside. One end of the shaft core extends through the shaft hole to the outside of the rotating base. The rotating base and the shaft core are rotatably connected. One end of the shaft core extends outward to form a retaining post. The bottom of the retaining post is provided with several engaging parts. Adjacent engaging parts are evenly distributed and form a retaining groove between adjacent engaging parts.

[0006] Furthermore, one end of the rotating base extends outward to form a fixing plate, and one end of the fixing base extends outward to form a positioning plate. Both the fixing plate and the positioning plate have several screw holes on their surfaces.

[0007] Furthermore, the surface of the shaft core is recessed inward to form an annular groove, and the retaining spring is disposed in the annular groove and is rotatably connected to the annular groove.

[0008] Furthermore, one end of the shaft extends outward to form a connecting portion, and the surface of the fixing seat is provided with a connecting hole that matches the connecting portion. One end of the connecting portion extends through the connecting hole to the outside of the fixing seat.

[0009] Furthermore, the surface of the positioning plate is also provided with elliptical holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the rotating shaft structure of this utility model for AR glasses achieves rapid installation of the rotating shaft structure through the equidistant engaging parts at the bottom of the locking post and the slots formed by adjacent engaging parts. The rotating shaft structure can be installed on the base of AR glasses by directly pressing and engaging. Compared with the traditional screw installation method, it can achieve rapid installation, fast installation speed and high installation efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The following is combined with Figures 1-4 A detailed description of a hinge structure for AR glasses according to this utility model is provided below:

[0019] A hinge structure for AR glasses includes a shaft core 4, a fixed base 2, and a rotatable rotating base 1. A retaining spring 9 is provided at the bottom of the rotating base 1, and a bushing 13 is provided at one end of the rotating base 1. The bushing 13 has an internal shaft hole 14 that matches the shaft core 4. One end of the shaft core 4 extends through the shaft hole 14 to the outside of the rotating base 1. The rotating base 1 and the shaft core 4 are rotatably connected. One end of the shaft core 4 extends outward to form a retaining post 5. Several engaging portions 6 are provided at the bottom of the retaining post 5. Adjacent engaging portions 6 are evenly spaced, and grooves 7 are formed between adjacent engaging portions 6. One end of the rotating base 1 extends outward to form a fixing plate 12, and one end of the fixing base 2 extends outward to form a positioning plate 11. The surfaces of the fixing plate 12 and the positioning plate 11 are provided with a plurality of screw holes 15. The surface of the shaft core 4 is recessed inward to form an annular groove 8. The snap ring 9 is disposed in the annular groove 8 and is rotatably connected to the annular groove 8. One end of the shaft core 4 extends outward to form a connecting part 3. The surface of the fixing base 2 is provided with a connecting hole 10 that matches the connecting part 3. One end of the connecting part 3 extends through the connecting hole 10 to the outside of the fixing base 2. The surface of the positioning plate 11 is also provided with an elliptical hole 16.

[0020] The fitting design of bushing 13 and shaft hole 14 makes the structure between shaft core 4 and rotating seat 1 more compact. The snap ring 9 is set at the bottom of rotating seat 1 and cooperates with shaft core 4 to form a limit, preventing rotating seat 1 from accidentally disengaging during rotation and improving reliability. The screw hole 15 on fixing plate 12 and positioning plate 11 and the elliptical hole 16 on positioning plate 11 allow the shaft structure to be quickly fixed with bolts, which is convenient for disassembly and maintenance. At the same time, it is suitable for the installation requirements of different AR glasses frames. The extended design of fixing plate 12 and positioning plate 11 disperses the force on the shaft, reduces local stress concentration, and extends service life. The fitting design of connecting part 3 and connecting hole 10 makes shaft core 4 and fixing seat 2 form a rigid connection, preventing shaft core 4 from moving axially and ensuring the stability of the overall structure of the shaft.

[0021] This embodiment provides a hinge structure for AR glasses. Through the equidistant engaging parts 6 at the bottom of the locking post 5 and the slots 7 formed by adjacent engaging parts 6, the hinge structure can be quickly installed. It can be installed onto the base of the AR glasses by directly pressing. Compared with the traditional screw installation method, it can achieve rapid installation, fast installation speed, and high installation efficiency.
