Abstract
Description
Technical Field
[0001] This application relates to the field of AR glasses technology, and more particularly to an AR glasses structure adapted for cable routing. Background Technology
[0002] Augmented reality (AR) glasses, as a next-generation computing platform, aim to seamlessly overlay virtual information onto the real world, providing users with an immersive experience. To achieve this goal, AR glasses typically integrate a miniature display optical engine and waveguide lenses. The display optical engine is responsible for generating images, while the waveguide lenses transmit the images emitted by the optical engine to the user's eye.
[0003] To achieve various complex functions, such as data acquisition, data transmission, power supply, and signal control, a large number of flexible cables need to be laid inside the frame and between the temples of AR glasses. These cables are responsible for connecting electronic components distributed inside the two temples, such as microdisplay driver circuits, sensor controllers, and battery management units, and / or connecting electronic components inside the temples with electronic components inside the frame (such as cameras and sensors), ensuring that the various functional modules work together.
[0004] However, existing AR glasses structures face a significant technical challenge in practical use. Due to user habits and wearing requirements, the temples of AR glasses frequently need to be bent, such as during storage, adjustment, or accidental stress. In existing technologies, the cables running at the connection between the frame and temples are highly susceptible to fatigue, breakage, or poor internal contact during frequent or significant bending. This damage not only directly leads to the malfunction of the AR glasses and shortens the product's lifespan but also significantly increases repair costs and user inconvenience, severely impacting the user experience.
[0005] Therefore, current AR glasses designs urgently need a technical solution that can effectively address the issue of cable damage caused by temple bending, in order to improve product reliability and durability. Utility Model Content
[0006] This application provides an AR glasses structure adapted for cable routing, which, while being closer in shape to traditional glasses, provides ample space for cable routing, thus solving the technical problem of cable damage due to bending.
[0007] To achieve the above objectives, this application provides an AR glasses structure adapted for cable routing, comprising a frame, a waveguide lens disposed within the frame, and a temple on each of the left and right sides of the frame, with the side of the temple relative to the frame considered the rear side, and the extension plane of the waveguide lens considered a vertical plane perpendicular to the front-rear direction. The front ends of both temples are connected to the frame via connecting components.
[0008] The connecting assembly includes temple sleeves and a light shield. The light shield is a C-shaped sleeve with an opening on one side. The axial direction of the light shield extends approximately in the front-to-back direction, and its opening is located on the side furthest from the outer edge of the frame on its left and right sides. The front end of the light shield is fixedly connected to the frame.
[0009] The temple sleeve includes a sleeve body for fixing the front end of the temple. The front end of the temple passes through the sleeve body. The front end of the sleeve body near the opening of the sunshade has two legs extending forward along the axial direction of the sleeve body. The two legs are vertically positioned on the upper and lower sides of the sleeve body. The upper leg is hinged to the upper side wall of the sunshade via a first hinge axis, and the lower leg is hinged to the lower side wall of the sunshade via a second hinge axis. The two legs form a gap for cables to pass through.
[0010] The frame has a first groove for accommodating cables, and the inner wall of the sleeve body has a second groove for cables to pass through. The frame also has a through hole that runs through the frame in the front-to-back direction and connects to the first groove.
[0011] The cable placed in the first groove passes through the wire hole, the gap between the two legs, and into the second groove.
[0012] Furthermore, an image display element is provided at the front of both the left and right temples. The image display element emits image light forward along the extension direction of the temple. The lens is a waveguide lens, which is used to guide the image light emitted by the image display element and the external ambient light into the human eye. The area of the waveguide lens used to receive the image light emitted by the image display element is the coupling area.
[0013] As is easily understood, the first hinge axis and the second hinge axis are coaxially arranged and extend in a vertical direction, and the temple sleeve rotates relative to the sunshade around the first hinge axis and the second hinge axis.
[0014] Optionally, the frame is provided with a light-transmitting hole at the coupling area of the waveguide lens to expose the coupling area, and the light-transmitting hole is located in the area surrounded by the light-shielding shield.
[0015] Optionally, the second groove extends along a direction parallel to the axis of the sleeve body and penetrates the sleeve body. After the cable passes through the second groove, it enters the interior of the temple.
[0016] The cable is used to connect electronic components inside the two temples, and / or to connect electronic components inside the temples to electronic components inside the frame.
[0017] The second groove and the wire hole are both located between the two legs, meaning that the second groove is located directly behind the gap formed between the two legs, and the wire hole is located directly in front of the gap formed between the two legs.
[0018] Preferably, both legs of the sleeve body are located on the side of the left and right sides of the sleeve that are closer to the opening of the light-shielding cover. The upper leg is hinged to the upper side wall of the opening of the light-shielding cover via a first hinge shaft, and the lower leg is hinged to the lower side wall of the opening of the light-shielding cover via a second hinge shaft.
[0019] Specifically, during the process of the temple opening from the retracted state to the open state, the sleeve body rotates in the positive direction around the first hinge axis and the second hinge axis with the temple until the axial extension direction of the sleeve body is perpendicular to the extension plane of the waveguide lens on its front side. At this time, the temple reaches the open state, and the light beam emitted from the image display element inside the light shield temple enters the coupling area through the light transmission hole.
[0020] During the process of the temple rotating in the opposite direction from the open state to the closed state, the sleeve body rotates in the opposite direction around the first hinge axis and the second hinge axis along with the temple until the temple reaches the closed state.
[0021] Preferably, a stop block is provided on the side of the frame near the opening of the sunshade. When the temple is in the retracted state, the sleeve body contacts the stop block, and the stop block restricts the continued rotation of the sleeve body.
[0022] In some preferred embodiments, when the temples are in the open state, the front end face of the temples is located within the light-transmitting aperture, thereby bringing the image display element of the temples closer to the waveguide lens. This requires the aperture diameter to be larger than the outer diameter of the temple front end so that the rotation of the temples about the hinge axis is not interfered with. Similarly, the axial length of the portion of the temple front end extending beyond the sleeve body is determined to not interfere with the rotation of the temples about the hinge axis, including but not limited to not affecting the temples reaching the retracted state.
[0023] In some preferred embodiments, the threading hole is located on one side of the light-transmitting hole and communicates with the light-transmitting hole.
[0024] One or more technical solutions in this application have at least the following technical effects or advantages:
[0025] This application creates a spatial channel for accommodating cables by setting a threading hole and the gap between the two legs. During the opening or closing of the temples, this spatial channel can provide a certain amount of space for the cables, allowing the cables to bend at large angles without being completely flush with the temples. This effectively avoids problems such as fatigue, breakage, or poor internal contact caused by frequent bending, thereby improving the reliability and durability of the product and enhancing the user experience.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0033] like Figure 1 As shown, this application provides an AR glasses structure adapted for cable routing, which includes a frame 100, a waveguide lens 200 disposed within the frame 100, and a temple 300 disposed on each of the left and right sides of the frame 100. The side of the temple 300 relative to the frame 100 is considered the rear side, and the extension plane of the waveguide lens 200 is considered a vertical plane perpendicular to the front-rear direction. The front ends of both temples 300 are connected to the frame 100 via connecting components. An image display element is disposed at the front of both the left and right temples 300. The image display element emits image light forward along the extension direction of the temple 300. The lens 200 is a waveguide lens 200, which is used to guide the image light emitted by the image display element and the external ambient light into the human eye. The area of the waveguide lens 200 used to receive the image light emitted by the image display element is the coupling area.
[0034] Combination Figure 1 , Figure 2 As shown, the connecting assembly includes a temple sleeve 401 and a light shield 402. The light shield 402 is a C-shaped sleeve with an opening on one side, meaning that any cross-section of the light shield 402 cut by a plane perpendicular to its axis is a C-shaped cross-section.
[0035] The sunshade 402 extends approximately along the front-to-back direction, with its opening located on the side furthest from the outer edge of the frame 100 on its left and right sides. The front end of the sunshade 402 is fixedly connected to the frame 100.
[0036] like Figure 3 As shown, the temple sleeve 401 includes a sleeve body 4011 for fixing the front end of the temple 300, and the front end of the temple 300 passes through the sleeve body 4011.
[0037] The front end of the sleeve body 4011 near the opening of the light-shielding cover 402 has two legs 4012 extending forward along the axial direction of the sleeve body 4011.
[0038] Two support legs 4012 are vertically positioned on the upper and lower sides of the sleeve body 4011. The upper support leg 4012 is hinged to the upper side wall of the light-shielding cover 402 via a first hinge shaft 403, and the lower support leg 4012 is hinged to the lower side wall of the light-shielding cover 402 via a second hinge shaft 404.
[0039] The first hinge shaft 403 and the second hinge shaft 404 are coaxially arranged and extend in the vertical direction. The temple sleeve 401 rotates relative to the light shield 402 around the first hinge shaft 403 and the second hinge shaft 404.
[0040] The two 4012 legs form a gap for the cable to pass through.
[0041] The frame 100 is provided with a light-transmitting hole 101 at the coupling area of the waveguide lens 200 for exposing the coupling area. The light-transmitting hole 101 is located in the area surrounded by the light-shielding cover 402.
[0042] Combination Figure 2 , Figure 3 , Figure 4 As shown, the frame 100 has a first groove 102 for accommodating cables, and the inner wall of the sleeve body 4011 has a second groove 4013 for cables to pass through. The second groove 4013 extends parallel to the axis of the sleeve body 4011 and penetrates the sleeve body 4011. The frame 100 also has a threading hole 103 that extends through the frame 100 in the front-to-back direction and connects to the first groove 102. Both the second groove 4013 and the threading hole 103 are located between the two legs 4012. Figure 5 As shown, the cable placed in the first groove 102 passes through the wire hole 103, the gap between the two legs 4012, and through the second groove 4013 before entering the interior of the temple 300.
[0043] The cable is used to connect the electronic components inside the two temples 300, and / or to connect the electronic components inside the temples 300 with the electronic components inside the frame 100.
[0044] The second groove 4013 and the wire hole 103 are both located between the two legs 4012, meaning that the second groove 4013 is located directly behind the gap formed between the two legs 4012, and the wire hole 103 is located directly in front of the gap formed between the two legs 4012.
[0045] Preferably, the two legs 4012 of the sleeve body 4011 are located on the left and right sides of the sleeve, closer to the opening of the light-shielding cover 402. The upper leg 4012 is hinged to the upper side wall of the opening of the light-shielding cover 402 through the first hinge shaft 403, and the lower leg 4012 is hinged to the lower side wall of the opening of the light-shielding cover 402 through the second hinge shaft 404.
[0046] Combination Figure 1 , Figure 6 As shown, specifically, during the process of the temple 300 opening from the retracted state to the open state, the sleeve body 4011 rotates forward with the temple 300 around the first hinge axis 403 and the second hinge axis 404 until the axial extension direction of the sleeve body 4011 is perpendicular to the extension plane of the waveguide lens 200 on its front side. At this time, the temple 300 reaches the open state, and the light beam emitted from the image display element inside the temple 300 of the light shield 402 enters the coupling area through the light transmission hole 101. Optionally, when the temple 300 reaches the open state, the temple shell fits against the frame for positioning. Alternatively, when the temple 300 reaches the open state, the outer wall of the sleeve body 4011 fits against the inner wall of the light shield 402 for positioning.
[0047] During the process of the temple 300 rotating in the opposite direction from the open state to the closed state, the sleeve body 4011 rotates in the opposite direction with the temple 300 around the first hinge axis 403 and the second hinge axis 404 until the temple 300 reaches the closed state.
[0048] Preferably, a stop block is provided on the side of the frame 100 near the opening of the sunshade 402. When the temple 300 is in the retracted state, the sleeve body 4011 contacts the stop block, and the stop block restricts the continued rotation of the sleeve body 4011.
[0049] In some preferred embodiments, when the temple 300 is in the open state, the front end face of the temple 300 is located within the light-transmitting aperture 101, thereby bringing the image display element of the temple 300 closer to the waveguide lens 200. This requires the aperture of the light-transmitting aperture 101 to be larger than the outer diameter of the front end of the temple 300 so that the rotation of the temple 300 around the hinge axis is not interfered with. Similarly, the axial length of the portion of the front end of the temple 300 extending beyond the sleeve body 4011 is determined to not interfere with the rotation of the temple 300 around the hinge axis, including but not limited to not affecting the temple 300 reaching the retracted state.
[0050] In some preferred embodiments, the thread hole 103 is disposed on one side of the light-transmitting hole 101 and communicates with the light-transmitting hole 101.
[0051] The advantage of this application is that by setting the wire hole 103, the interval between the two legs 4012 and the second groove 4013, a spatial channel for accommodating the cable is formed. During the opening or closing of the temple 300, this spatial channel can provide a certain amount of space for the cable, allowing the cable to bend at a large angle without being completely flush with the temple 300. This effectively avoids problems such as fatigue, breakage or poor internal contact caused by frequent bending, improves the reliability and durability of the product, and enhances the user experience.
