Description

Technical Field

[0001] This utility model relates to the field of smart wearable technology, and in particular to an AR glasses. Background Technology

[0002] AR (Augmented Reality) glasses can provide users with virtual text, images, and videos, as well as allow them to view real-world scenes. The virtual content and real-world scenes can be integrated and interacted with to meet users' needs in various fields such as entertainment, consumption, education, social interaction, and industrial production.

[0003] For individuals with visual impairments, such as myopia, hyperopia, and astigmatism, using AR glasses can easily lead to blurred vision and dizziness due to refractive errors. To address these issues, some manufacturers currently install refractive lenses into AR glasses, but this method is complex and makes lens replacement inconvenient. Utility Model Content

[0004] This invention provides AR glasses that allow for easy replacement of refractive lenses and have a simple structure.

[0005] This utility model provides an AR glasses, including: a frame with a receiving groove, the inner side wall of which is provided with a first groove; a refractive lens, which is detachably disposed in the receiving groove, and an elastic element is provided on the outer peripheral side of the refractive lens, the elastic element being used to snap into the first groove so that the refractive lens is fixed in the receiving groove.

[0006] In one possible implementation, the shape of the receiving groove is adapted to the shape of the refractive lens to position the refractive lens within the receiving groove.

[0007] In one possible implementation, the elastic element is fixedly connected to the outer periphery of the refractive lens.

[0008] In one possible implementation, the elastic element is a sealing ring.

[0009] In one possible implementation, a second groove is provided on the outer periphery of the refractive lens, with part of the sealing ring located in the second groove and the other part used to engage with the first groove.

[0010] In one possible implementation, the elastic element is an elastic protrusion disposed on the outer periphery of the refractive lens, and at least three elastic protrusions are disposed along the circumference of the refractive lens.

[0011] In one possible implementation, a handle is provided on the outer periphery of the refractive lens.

[0012] In one possible implementation, the handle has a clearance portion for avoiding the elastic element, which abuts against the frame when the refractive lens is fixed in the receiving groove.

[0013] In one possible implementation, the refractive lens is molded as a single piece with the handle.

[0014] In one possible implementation, the refractive lens includes at least one of myopia lenses, hyperopia lenses, and astigmatism lenses.

[0015] The AR glasses provided by this utility model have a receiving groove on the frame for accommodating a refractive lens. The refractive lens is engaged with a first groove in the receiving groove by an elastic member on its outer periphery, thus realizing the installation of the refractive lens. After the elastic member is engaged into the first groove, it forms a positioning with the receiving groove. Under the action of the elastic member, friction is generated between the elastic member and the receiving groove, which can ensure the stability of the refractive lens installation. When it is necessary to remove the refractive lens, it is only necessary to overcome the elastic force of the elastic member to pull the refractive lens out of the receiving groove, which facilitates the replacement of the refractive lens and has a simple structure.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The following is combined Figures 1-7 This invention describes an AR glasses embodiment, comprising a frame 1 and a refractive lens 2, wherein:

[0030] The frame 1 has a receiving groove 11, and a first groove 12 is provided on the inner side wall of the receiving groove 11.

[0031] The refractive lens 2 is detachably installed in the receiving groove 11. An elastic element 3 is provided on the outer periphery of the refractive lens 2. The elastic element 3 is used to snap into the first groove 12 so that the refractive lens 2 is fixed in the receiving groove 11.

[0032] Specifically, the frame 1 includes two temples and two receiving slots 11, each for mounting two refractive lenses 2. An AR lens is also mounted on the frame 1 to enable the glasses' AR function; details will not be elaborated here. The AR lens is fixedly mounted on the frame 1. After the refractive lenses 2 are installed in the receiving slots 11, they are spaced apart from the AR lens; specifically, the refractive lenses 2 are located between the AR lens and the eye.

[0033] In this invention, a receiving groove 11 for accommodating a refractive lens 2 is provided on the frame 1. The refractive lens 2 is installed by engaging with the first groove 12 in the receiving groove 11 through the elastic member 3 on the outer periphery. The elastic member 3 is positioned with the receiving groove 11 after being engaged with the first groove 12 by its own elasticity. Under the action of the elastic member 3, friction is generated between it and the receiving groove 11, which can ensure the stability of the installation of the refractive lens 2. When it is necessary to remove the refractive lens 2, it is only necessary to overcome the elastic force of the elastic member 3 to pull the refractive lens 2 out of the receiving groove 11, which makes it convenient to replace the refractive lens 2 and the structure is simple.

[0034] Specifically, by setting a first groove 12 on the inner wall of the receiving groove 11 and setting an elastic element 3 on the outer periphery of the refractive lens 2, the technical problem of replacing the refractive lens 2 of AR glasses is cleverly solved. In practical application scenarios, such as when AR glasses are used for teaching in educational institutions, different students may have different degrees of vision problems. Traditional AR glasses require each person to be equipped with a pair, which is costly. However, with this solution, only one pair of AR glasses and multiple refractive lenses 2 of different degrees are needed. When replacement is required, the elastic deformation characteristics of the elastic element 3 allow the lens to be quickly inserted or removed. The entire process requires no tools and is simple and intuitive to operate. The elastic element 3 can be made of various materials such as silicone and rubber. The choice of different materials will affect the service life and assembly feel. In some optional embodiments, the elastic element 3 can also be made of other forms such as metal spring sheets. Although this solution has a slightly higher manufacturing cost, it can provide a more durable elastic effect.

[0035] In some embodiments, the shape of the receiving groove 11 is adapted to the shape of the refractive lens 2 for positioning the refractive lens 2 within the receiving groove 11.

[0036] In this invention, the problem of accurate lens installation is solved by adapting the shape of the receiving groove 11 to the refractive lens 2. In practical applications, such as when using AR glasses to assist surgery in medical procedures, the requirements for image clarity and accuracy are extremely high; even slight deviations in the lens can affect the surgical outcome. The shape-adaptive design, like assembling... Figure 1 Thus, the lens can only be inserted into the receiving slot 11 in the correct orientation, avoiding the possibility of misalignment. This design can be further optimized, for example, by designing an asymmetrical positioning structure on the receiving slot 11 and the edge of the lens to ensure that the lens can only be installed in one correct orientation, further improving the reliability and convenience of assembly.

[0037] In some embodiments, the elastic element 3 is fixedly connected to the outer periphery of the refractive lens 2.

[0038] This embodiment of the invention clarifies the fixed connection method between the elastic element 3 and the refractive lens 2, solving the potential problem of the elastic element 3 detaching during long-term use. In practical application scenarios, such as when using AR glasses for equipment maintenance in industrial settings, the environment may present adverse factors such as vibration and impact. The fixed connection between the elastic element 3 and the lens ensures reliable use in harsh environments. The fixed connection can be achieved in various ways, such as hot pressing and adhesive bonding, each with its own characteristics. For example, hot pressing is simple but requires good material compatibility, while adhesive bonding has a wide range of applications but requires the selection of a suitable adhesive.

[0039] like Figure 5 , 6 As shown, in some embodiments, the elastic element 3 is a sealing ring 31.

[0040] In this invention, the elastic element 3 is specifically embodied as a sealing ring 31, which not only achieves the function of fixing the lens but also provides a dustproof and waterproof sealing effect. When using AR glasses in outdoor sports and other scenarios, they may encounter rain, dust, and other factors. The design of the sealing ring 31 ensures both lens fixation and protection. The sealing ring 31 can be made of different materials, such as fluororubber, which has excellent weather resistance and chemical stability and is suitable for use in harsh environments; and silicone rubber, which has good biocompatibility and is suitable for use in situations where it is in close contact with the skin for extended periods.

[0041] In some embodiments, a second groove 21 is provided on the outer periphery of the refractive lens 2, and a portion of the sealing ring 31 is located in the second groove 21, while the other portion is used to be inserted into the first groove 12.

[0042] In this invention, a second groove 21 is provided on the outer periphery of the refractive lens 2, which engages with the sealing ring 31 in a snap-fit ​​manner, providing a more reliable fixation effect. In practical applications, such as VR gaming environments, where users may experience vigorous head movements, this double-snap design ensures that the lens will not fall off under any circumstances. The depth, width, and other parameters of the groove can be adjusted according to actual needs to balance assembly difficulty and fixation strength. For example, increasing the groove depth can improve fixation strength, but it will also increase assembly difficulty.

[0043] Specifically, a portion of the sealing ring 31 is located inside the second groove 21 and is fixedly connected to the second groove 21, while the other portion is located outside the second groove 21 and is used to be inserted into the first groove 12. The radial width of the sealing ring 31 inserted into the first groove 12 is between 0.5mm and 1.0mm, which ensures a safe gap between the refractive lens 2 and the inner wall of the receiving groove 11, and also provides sufficient friction to prevent the sealing ring 31 from being squeezed and deformed and unable to enter the first groove 12.

[0044] like Figure 7As shown, in some embodiments, the elastic element 3 is an elastic protrusion 32 disposed on the outer periphery of the refractive lens 2, and at least three elastic protrusions 32 are disposed along the circumference of the refractive lens 2.

[0045] This embodiment of the invention provides another implementation of the elastic element 3—elastic protrusions 32, with at least three points providing stable support. This design has unique advantages in some special applications, such as reducing the impact of thermal deformation when used in high-temperature environments. The number, position, and size of the elastic protrusions 32 can be adjusted according to requirements; for example, increasing the number of protrusions can improve support stability, but it also increases manufacturing difficulty.

[0046] Specifically, the elastic protrusion 32 can adopt a strip structure, a semi-circular structure, etc., so that the elastic protrusion 32 can be partially inserted into the first groove 12, ensuring the contact area between the elastic protrusion 32 and the first groove 12, and ensuring the friction between the elastic protrusion 32 and the first groove 12.

[0047] In some embodiments, a handle 22 is provided protruding from the outer periphery of the refractive lens 2.

[0048] In this invention, the handle 22, located around the outer periphery of the refractive lens 2, significantly improves ease of operation. In practical use, such as when elderly people use AR glasses, they may experience insufficient finger dexterity; the handle 22 design allows them to easily change lenses. The shape and size of the handle 22 can be optimized according to ergonomic principles, for example, by designing anti-slip textures to improve grip, or by adopting an arc design that conforms to the shape of the fingers.

[0049] In some embodiments, the handle 22 has a clearance portion 23 for avoiding the elastic member 3, which abuts against the frame 1 when the refractive lens 2 is fixed in the receiving groove 11.

[0050] In this invention, by providing a clearance portion 23 on the handle 22, both aesthetics are ensured and tactile feedback indicating proper installation is provided. In actual use, the user can sense that the lens has been installed correctly through the contact between the clearance portion 23 and the frame 1. This tactile feedback is particularly suitable for visually impaired users.

[0051] Furthermore, the design of the avoidance section 23 can also include a guide ramp to make the installation process smoother.

[0052] In some embodiments, the refractive lens 2 is integrally formed with the handle 22.

[0053] In this invention, the integrated design of the handle 22 and the refractive lens 2 improves structural strength and reduces production costs. In mass production scenarios, this design simplifies production processes and improves production efficiency. The integrated molding can be achieved using various processes such as injection molding and 3D printing; different processes are suitable for different production scales and material selections.

[0054] In some embodiments, the refractive lens 2 includes at least one of myopia lens, hyperopia lens, and astigmatism lens.

[0055] This utility model embodiment clarifies the specific type of refractive lens 2, expanding the product's applicability. In practical applications, the appropriate lens type can be selected based on the user's vision condition. For example, farsighted lenses may be more commonly used in educational settings for the elderly, while nearsighted lenses may be more commonly used among teenagers. Different types of lenses can employ different optical designs and coating processes to optimize visual effects.

[0056] In some embodiments, a limiting boss is also provided in the receiving groove 11. The limiting boss limits the refractive lens 2 installed in the receiving groove 11, thereby positioning the refractive lens 2 and ensuring that the refractive lens 2 can be installed in place. This ensures that the elastic element 3 can be fully engaged in the first groove 12, guaranteeing the stability and reliability of the refractive lens 2 installation. Furthermore, the reliability of the refractive lens 2 installation can be ensured by checking whether the handle 22 is in contact with the frame.

[0057] In this embodiment of the invention, reliable fixing is achieved through the sealing ring 31, while convenient operation and positioning feedback are achieved through the handle 22 and the clearance part 23. This combination not only ensures the realization of basic functions but also provides an excellent user experience. Through the synergistic effect of shape adaptation, fixed connection, and sealing ring 31, installation accuracy is ensured while also providing protective functions. The combined effect exceeds the sum of the effects of each claim when used individually.

[0058] The AR glasses feature a receiving groove 11 on the frame 1 for accommodating a refractive lens 2. The refractive lens 2 is engaged with a first groove 12 within the receiving groove 11 via an outer elastic element 3. The elastic element 3, after being engaged into the first groove 12, forms a positioning with the receiving groove 11. Furthermore, friction is generated between the elastic element 3 and the receiving groove 11, ensuring the stability of the refractive lens 2 installation. When the refractive lens 2 needs to be removed, it is only necessary to overcome the elastic force of the elastic element 3 to pull the refractive lens 2 out of the receiving groove 11, making it convenient to replace the refractive lens 2. The structure is also simple.
