Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to an eyeglass. Background Technology

[0002] In ordinary eyeglasses, the lens and frame are typically made of rigid PC (polycarbonate). During assembly, the lens deforms to engage with the frame, securing it in a groove. This locking mechanism ensures the lens won't easily detach even after impact or drop. However, because this deformation is necessary, the lens may not fully recover from the deformation, leaving internal stress unrelieved and increasing the risk of lens dislodgement upon impact. For smart glasses, the lenses are even more delicate. For example, waveguide lenses rely on total internal reflection for imaging. Deformation altering the lens's shape and refractive index can cause light transmission deviation or even prevent imaging. Therefore, in smart glasses, lens assembly must be deformation-free. Utility Model Content

[0003] Given the risks of lens deformation and easy detachment after assembly in existing eyeglasses, it is necessary to provide a new type of eyeglasses.

[0004] The eyeglasses provided in this application include:

[0005] A picture frame having a mounting hole and a mounting groove recessed from the inner sidewall of the mounting hole, the mounting groove having a groove bottom, an outer frame surface extending forward from the groove bottom, and an inner frame surface extending rearward from the groove bottom;

[0006] The temples are mounted at the rear of the frame;

[0007] A lens, mounted in the mounting hole, includes a light-transmitting portion and a structural portion located at the edge of the light-transmitting portion and engaging with the mounting groove. The structural portion has an outer mating surface facing the outer frame surface and an inner mating surface facing the inner frame surface.

[0008] A flexible component is embedded between the lens and the frame. The flexible component has an outer filling section located between the outer frame surface and the outer mating surface, and an inner filling section located between the inner frame surface and the inner mating surface. The thickness of the inner filling section is greater than the thickness of the outer filling section.

[0009] With this configuration, during assembly, the flexible component can wrap around the lens structure and be inserted into the mounting groove of the frame. By embedding the flexible component between the frame and the lens, the flexible component deforms under pressure after assembly, thus fixing the lens to the frame. This achieves assembly while preventing significant lens deformation, ensuring the lens's optical performance. Furthermore, by setting the thickness of the inner filling section of the flexible component to be greater than the thickness of the outer filling section, during assembly, the thinner outer filling section of the flexible component can be selected to enter the mounting groove first. After the lens is assembled, the thicker inner filling section of the flexible component is squeezed into the mounting groove and applies a forward pushing force to the lens structure, ensuring the reliability of the connection between the lens, the flexible component, and the frame after assembly.

[0010] In one embodiment of this application, the angle between the outer frame surface and the front-to-back direction of the mirror frame is greater than the angle between the inner frame surface and the front-to-back direction of the mirror frame.

[0011] With this configuration, the mounting slot faces further back, allowing the outer frame to provide sufficient stopping force during assembly, ensuring that the lens, which is wrapped by the flexible component, can be stably inserted into the mounting slot.

[0012] In one embodiment of this application, the thickness of the end of the outer filling section away from the bottom of the tank is greater than the thickness of the end of the outer filling section near the bottom of the tank; the thickness of the end of the inner filling section away from the bottom of the tank is greater than the thickness of the end of the inner filling section near the bottom of the tank.

[0013] With this design, the thickness of the flexible section is designed so that, after assembly, the pressure exerted on the two ends of the flexible component by the lens, frame, and flexible parts is greater than that at the center of the flexible component due to the thickness difference. This strengthens the clamping effect of the mounting groove on the lens, which helps to reduce lens movement when the glasses are hit and ensures the reliability of the assembly between the lens, flexible parts, and frame.

[0014] In one embodiment of this application, the outer filling section extends gradually from the bottom of the groove toward the front side of the frame, and the inner filling section extends gradually from the bottom of the groove toward the rear side of the frame.

[0015] With this design, the outer and inner filling sections fit tightly to the lens and frame, and the flexible components fully fill the space between the lens and frame, which helps to reduce the risk of misalignment between the lens and frame after an impact.

[0016] In one embodiment of this application, the eyeglasses further include a spring pin fixed to the inner frame surface, the spring pin being located behind the structural portion.

[0017] With this design, when the outer frame is tilted too much and the lens is prone to falling off the outer frame, a spring pin can be further installed on the inner frame facing the lens to prevent the lens from falling off.

[0018] In one embodiment of this application, the frame further has a positioning groove located on the outer frame surface and / or the inner frame surface, and the flexible member further has a positioning protrusion protruding from the outer filling section and / or the inner filling section, the positioning protrusion engaging with the positioning groove.

[0019] With this setup, during assembly, the protrusions can be aligned with the grooves first, and the lens portion corresponding to the protrusions can be inserted into the frame. The positioning and cooperation between the protrusions and grooves assists in the installation, which helps to accurately install the lens into the mounting hole.

[0020] In one embodiment of this application, the flexible component is integrally formed on the structural portion of the lens, and both the flexible component and the lens are injection molded parts.

[0021] This design ensures that the flexible components and the lens will not shift or misalign during assembly, thus guaranteeing the accuracy of the lens installation position after assembly.

[0022] In one embodiment of this application, the flexible element is bonded to the structural portion of the lens.

[0023] With this setup, the flexible component can be fitted onto the lens structure before assembly, and then adhesive bonding can be used to further increase the reliability of the connection between the flexible component and the lens, avoiding misalignment between the flexible component and the lens during assembly.

[0024] In one embodiment of this application, the picture frame includes a front frame providing the outer frame surface and a rear frame providing the inner frame surface, wherein the front frame is glued to the rear frame.

[0025] This design, through modular assembly, simplifies frame production and facilitates demolding.

[0026] In one embodiment of this application, the rear frame has a snap-fit ​​groove, and the front frame has a snap-fit ​​block that engages with the snap-fit ​​groove.

[0027] This design, through the snap-fit ​​of the slots and blocks, facilitates the quick positioning of the front and rear frames, thereby improving assembly efficiency. Attached Figure Description

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0039] In ordinary eyeglasses, the lenses and frames are typically made of rigid PC (polycarbonate). During assembly, the lens deforms to engage with the frame, securing it in a groove. This locking mechanism ensures the lens won't easily detach even after impact or drop. However, because the lens relies on deformation to engage, this deformation can be irreversible. The internal stress within the lens cannot be released, leaving a high risk of lens detachment upon impact.

[0040] For smart glasses, the lenses are more precise. Taking waveguide lenses as an example, optical waveguide imaging relies on total internal reflection of the lens surface. Changes in lens shape and refractive index caused by lens deformation can easily lead to light transmission deviation in the optical waveguide or even failure to form an image. Therefore, in smart glasses, lens assembly requires that the lens cannot be deformed. Moreover, from the perspective of imaging function, smart glasses have higher requirements for the accuracy of the relative position between the lens and the frame.

[0041] Therefore, it is necessary to provide eyeglasses in which the lens is securely attached to the frame and the lens is not easily deformed during assembly.

[0042] Please see Figures 1 to 3 In one embodiment provided in this application, the eyeglasses include a frame 10, temples (not shown), lenses 20, and a flexible member 30; wherein, the frame 10 has a mounting hole 101 and a mounting groove 102 recessed from the inner sidewall of the mounting hole 101, the mounting groove 102 has a groove bottom 1021, an outer frame surface 1022 extending forward from the groove bottom 1021, and an inner frame surface 1023 extending rearward from the groove bottom 1021; the temples are mounted at the rear of the frame 10; the lenses 20 are mounted in the mounting hole 101, including a light-transmitting portion 21 and... The structural part 22 is located at the edge of the light-transmitting part 21 and engages with the mounting groove 102. The structural part 22 has an outer mating surface 201 facing the outer frame surface 1022 and an inner mating surface 202 facing the inner frame surface 1023. The flexible member 30 is embedded between the lens 20 and the frame 10. The flexible member 30 has an outer filling section 31 located between the outer frame surface 1022 and the outer mating surface 201 and an inner filling section 32 located between the inner frame surface 1023 and the inner mating surface 202. The thickness of the inner filling section 32 is greater than the thickness of the outer filling section 31. This application provides eyeglasses with a flexible member 30 between the lens 20 and the frame 10. During assembly, the flexible member 30 can wrap around the structural portion 22 of the lens 20 and insert it into the mounting groove 102 of the frame 10, protecting the structural portion 22 of the lens 20 and preventing significant deformation of the lens 20 during assembly. By embedding the flexible member 30 between the frame 10 and the lens 20, the flexible member 30 deforms under pressure after assembly, thereby fixing the lens 20 to the frame 10. During and after assembly, the lens 20 does not deform significantly. The large deformation ensures the optical performance of the lens 20. By setting the thickness of the inner filling section 32 of the flexible member 30 to be greater than the thickness of the outer filling section 31, during assembly, the thinner outer filling section 31 of the flexible member 30 can be selected to enter the mounting groove 102 first. After the lens 20 is assembled, the thicker inner filling section 32 of the flexible member 30 is squeezed into the mounting groove 102 and applies a forward pushing force to the structural part 22 of the lens 20, ensuring the reliability of the connection between the lens 20, the flexible member 30 and the frame 10 after assembly.

[0043] Optionally, considering that the lens 20, which is wrapped by the flexible member 30, needs to be inserted into the mounting hole 101 from the rear to the front during assembly, in order to avoid the lens 20 passing through the mounting hole 101 during installation, in one embodiment of this application, the tilt angle α between the outer frame surface 1022 and the front-rear direction of the frame 10 is greater than the tilt angle β between the inner frame surface 1023 and the front-rear direction of the frame 10. That is, the groove opening of the mounting groove 102 is more rearward. During assembly, the outer frame surface 1022 can provide sufficient stopping force to ensure that the lens 20 wrapped by the flexible member 30 can be stably inserted into the mounting groove 102.

[0044] Optionally, in one embodiment provided in this application, the thickness of the end of the outer filling section 31 away from the bottom of the groove 1021 is greater than the thickness of the end of the outer filling section 31 near the bottom of the groove 1021; the thickness of the end of the inner filling section 32 away from the bottom of the groove 1021 is greater than the thickness of the end of the inner filling section 32 near the bottom of the groove 1021. In this way, by designing the thickness of the flexible section, after assembly, due to the existence of the thickness difference, the compressive force at both ends of the flexible member 30 is greater than the compressive force at the center of the flexible member 30, thereby strengthening the clamping effect of the mounting groove 102 on the lens 20, which helps to reduce the shaking of the lens 20 when the glasses are hit, and ensures the reliability of the assembly between the lens 20, the flexible member 30 and the frame 10.

[0045] Optionally, to improve the stability of the relative position between the lens 20 and the frame 10, in one embodiment provided in this application, the outer filling section 31 extends gradually from the bottom of the groove 1021 toward the front side of the frame 10, and the inner filling section 32 extends gradually from the bottom of the groove 1021 toward the rear side of the frame 10. After assembly, the outer filling section 31 and the inner filling section 32 fit tightly with the lens 20 and the frame 10, and the flexible member 30 fully fills the space between the lens 20 and the frame 10, which helps to reduce the risk of misalignment between the lens 20 and the frame 10 after impact.

[0046] Optionally, when the tilt of the outer frame 1022 is so large that the lens 20 is easily detached from the outer frame 10, in one embodiment provided in this application, the eyeglasses also include a spring pin fixed to the inner frame 1023, the spring pin being located behind the structural part 22 to prevent the lens 20 from accidentally detaching.

[0047] Optionally, to increase the accuracy of positioning between the flexible member 30 and the frame 10, in one embodiment provided in this application, the frame 10 further has positioning grooves located on the outer frame surface 1022 and / or the inner frame surface 1023, and the flexible member 30 further has positioning protrusions protruding from the outer filling section 31 and / or the inner filling section 32, the positioning protrusions engaging with the positioning grooves. During assembly, the protrusions can be aligned with the grooves first, and the corresponding portion of the lens 20 is then inserted into the frame 10. The positioning and engagement of the protrusions and grooves assists in the installation, facilitating the accurate installation of the lens 20 in the mounting hole 101.

[0048] Optionally, in one embodiment provided in this application, the flexible component 30 is integrally formed on the structural portion 22 of the lens 20, and both the flexible component 30 and the lens 20 are injection molded parts. Specifically, the flexible component 30 and the lens 20 can be integrally formed using a two-color injection molding process. During actual assembly, the flexible component 30 and the lens 20 will not shift or misalign, which helps to ensure the accuracy of the lens 20's installation position after assembly.

[0049] Optionally, in one embodiment provided in this application, the flexible member 30 is glued to the structural portion 22 of the lens 20. Before assembly, the flexible member 30 can be fitted onto the structural portion 22 of the lens 20, and then glued to further increase the reliability of the connection between the flexible member 30 and the lens 20, avoiding misalignment between the flexible member 30 and the lens 20 during assembly.

[0050] like Figure 2 and Figure 3 As shown, optionally, in one embodiment provided in this application, the eyeglass frame 10 includes a front frame 11 providing an outer frame surface 1022 and a rear frame 12 providing an inner frame surface 1023, with the front frame 11 glued to the rear frame 12. This modular assembly method simplifies the production of the eyeglass frame 10 and facilitates demolding. It is understood that in other embodiments, the front frame 11 can also be assembled with the rear frame 12 to form the eyeglass frame 10 by means of snap-fit ​​connection or bolt connection.

[0051] Furthermore, in one embodiment provided in this application, the rear frame 12 has a snap-fit ​​groove 121, and the front frame 11 has a snap-fit ​​block 111 that engages with the snap-fit ​​groove 121. The snap-fit ​​between the snap-fit ​​groove 121 and the snap-fit ​​block 111 facilitates quick positioning of the front frame 11 and the rear frame 12, thereby improving assembly efficiency. Specifically, the snap-fit ​​groove 121 and the snap-fit ​​block 111 are shaped to improve the assembly accuracy of the frame 10. The mounting groove 102 has a defined shape after the front frame 11 and the rear frame 12 are assembled and will not deform, ensuring assembly accuracy during subsequent installation of the lens 20.

[0052] Optionally, in one embodiment provided in this application, the flexible member 30 is made of silicone.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
