Description

Technical Field

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

[0002] Optical waveguide technology, with its unique advantage of integrating complex optical systems into thin lenses, has become the mainstream technological path for achieving lightweight and stylish designs in consumer-grade AR glasses. By performing total internal reflection of the virtual image light generated by a microdisplay within the waveguide lens and coupling it out to the human eye, optical waveguide technology makes AR glasses resemble ordinary glasses in form, laying the foundation for everyday wear. However, in its path to large-scale commercial application, especially in outdoor mobile scenarios, this technology has revealed a core technological bottleneck that has long remained unresolved: under strong ambient light conditions outdoors, the visibility and clarity of virtual images drop sharply.

[0003] To address these issues, some manufacturers have pursued costly and problematic approaches to increasing hardware brightness. The industry has primarily focused on enhancing light source brightness through more advanced microdisplays. However, achieving ultra-high brightness levels of several thousand nits means an exponential increase in chip power consumption and heat generation. This poses a significant challenge to the limited battery capacity and miniaturized heat dissipation design of AR glasses, often resulting in drastically reduced battery life and increased size and weight, contradicting the consumer product's need for portability and long battery life.

[0004] Therefore, those skilled in the art have long sought a solution that can efficiently and cost-effectively improve the display performance of waveguide AR glasses in strong light, without significantly increasing device power consumption, weight, and size, and without affecting the user's natural observation of the real environment when needed. Existing technologies have failed to provide a mature solution that strikes a good balance between convenience and cost-effectiveness. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a support structure for AR glasses that is convenient to use and low in cost.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An AR glasses support structure includes a clamp and a sunglasses lens, the sunglasses lens being fitted onto the clamp and mounted on the bridge of the AR glasses via the clamp; The clamp has a clamping groove on one side, the width of which is adapted to the thickness of the sunglasses lens, and the sunglasses lens is tightly fitted in the clamping groove; the clamp has a slot on the other side, and the clamp is fastened to the bridge of the AR glasses through the slot.

[0007] The clamp includes a body, an upper clamping block, a lower clamping block, and a clamping piece. The clamping piece is connected to one side of the body and cooperates with the body to form the clamping groove. The upper clamping block and the lower clamping block are connected to the other side of the body and cooperate with the body to form the clamping groove.

[0008] Both the upper and lower locking blocks have a protruding edge on the side away from the main body.

[0009] The upper block is provided with an avoidance hole.

[0010] The lower locking block has an arc-shaped structure.

[0011] By adopting the above solution, this invention uses a clamp to attach a sunglasses lens to the outside of the AR glasses. Through innovative structural design, it effectively solves the industry pain point of poor virtual image visibility in outdoor strong light environments for waveguide AR glasses. This invention not only achieves a qualitative leap in display performance but also demonstrates significant advantages in user experience, versatility, and economy, providing strong support for the promotion and application of consumer-grade and industrial-grade AR technology in a wider range of outdoor scenarios.

Detailed Implementation

[0014] like Figure 1-3As shown, this utility model discloses a support structure for AR glasses, which includes a clamp 30 and a sunglasses lens 20. The sunglasses lens 20 is mounted on the clamp 30 and installed on the bridge 11 of the AR glasses 10 via the clamp 30. Specifically, one side of the clamp 30 has a clamping groove 36, the width of which is adapted to the thickness of the sunglasses lens 20, and the sunglasses lens 20 is tightly fitted in the clamping groove 36. The other side of the clamp 30 has a slot 34, through which the clamp 30 is engaged with the bridge 11 of the AR glasses 10.

[0015] like Figure 4 and Figure 5 As shown, in this embodiment, the clamp 30 includes a body 31, an upper clamping block 32, a lower clamping block 33, and a clamping piece 35. The clamping piece 35 is connected to one side of the body 31, and the electrode and the body 31 cooperate to form a clamping groove 36. In use, the width of the clamping groove 36 is equal to or slightly less than the thickness of the sunglasses lens 20, so when the sunglasses lens 20 is inserted into the clamping groove 36, the clamping piece 35 and the body 31 will tightly clamp the sunglasses lens 20. The upper clamping block 32 and the lower clamping block 33 are connected to the other side of the body 31, and the upper clamping block 32, the lower clamping block 33 and the body 31 cooperate to form a clamping groove 34. The upper clamping block 32 and the lower clamping block 33 each have a protruding edge on the side away from the body 31. The protruding edge on the upper clamping block 32 is the upper protruding edge 321, and the protruding edge on the lower clamping block 33 is the lower protruding edge 331. When the slot 34 engages the nose bridge 11 of the AR glasses 10, the upper protruding edge 321 and the lower protruding edge 331 are in close contact with the inner side of the nose bridge 11, ensuring the stability of the connection between the clamp 30 and the AR. When the AR glasses 10 is without a nose pad, its nose bridge 11 is in direct contact with the nose. Therefore, the lower locking block 33 has an arc-shaped structure to ensure that the AR glasses 10 can be well supported on the nose.

[0016] AR glasses 10 typically have sensors. Therefore, to ensure the normal sensing function of the sensors, the upper locking block 32 is provided with a clearance hole 322. In this embodiment, the clearance hole 322 extends through both the upper and lower ends of the upper locking block 32.

[0017] This utility model uses a clamp 30 to mount a sunglass lens 20 on the outside of the AR glasses 10. Through this innovative structural design, it effectively solves the industry pain point of poor virtual image visibility in outdoor strong light environments for the waveguide AR glasses 10. Specifically, it includes: I. Significantly improves outdoor display performance, enabling AR glasses to achieve clear visibility.

[0018] By effectively attenuating strong ambient light entering the eyes through the sunglass lens 20, the intensity of background light is significantly reduced, making the eyes more comfortable. This allows previously "submerged" virtual images to stand out from the background, significantly improving the contrast between virtual information and the real environment. Users can clearly see navigation, information prompts, and other content displayed in the glasses in bright outdoor conditions without relying on ultra-high brightness, expensive, and power-consuming optical waveguide display modules. In addition, some diffractive waveguide schemes can produce distracting rainbow patterns at certain angles. The sunglass lens 20, as a physical filter layer, can filter and weaken these stray lights to a certain extent, thereby reducing the visual interference of rainbow patterns and providing a cleaner display image.

[0019] Second, it possesses excellent versatility and economy, enabling wide compatibility. Plug and play, convenient and efficient: Featuring a snap-on design, users can quickly install or remove the glasses depending on lighting conditions. When entering indoor or dimly lit environments, the sunglasses lens 20 can be easily removed to restore the AR glasses 10 to its original light-transmitting state, achieving seamless switching between different scenarios and greatly improving the convenience and flexibility of use.

[0020] Wide compatibility: This invention does not rely on the internal principles of specific optical waveguide technologies (such as arrayed optical waveguides or diffractive optical waveguides) and can be used as a universal add-on solution, compatible with various AR glasses 10 platforms that use optical waveguide technology.

[0021] Low cost and high efficiency: This utility model effectively solves the outdoor visibility problem that high-end AR glasses can only partially solve with low additional costs, thus lowering the threshold for a high-quality AR experience.

[0022] In summary, this invention successfully overcomes a key bottleneck in the outdoor application of waveguide AR glasses 10 through an ingenious external solution. It not only achieves a qualitative leap in display performance but also demonstrates significant advantages in user experience, versatility, and cost-effectiveness, providing strong support for the promotion and application of consumer-grade and industrial-grade AR technology in a wider range of outdoor scenarios.

[0023] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
