[0044] like Figure 1 and Figure 2 As shown, this embodiment provides a glasses frame, including a frame 1, temples 2, and a hinge assembly 3. The temples 2 are connected to the frame 1 via the hinge assembly 3. The frame 1 has a first mounting groove 10; the temples 2 have a second mounting groove 20; the hinge assembly 3 includes an elastic member 31 and a pivot connector 32. One end of the elastic member 31 extends into the first mounting groove 10 and is detachably connected to the frame 1. The other end of the elastic member 31 extends into the second mounting groove 20, and the other end of the elastic member 31 is bent to form a through hole 3121. The pivot connector 32 passes through the through hole 3121 and is detachably connected to the temples 2.
[0045] The temples 2 of the frame are detachably connected to the frame 1 and temples 2 via hinge assembly 3. The hinge assembly 3 has a simple structure and the frame is easy to disassemble. When the temples 2 are spread at a large angle, the elastic element 31 resists the temples 2 and undergoes elastic deformation, which can provide a certain clamping force for the temples 2 to clamp the user's head, so as to ensure the stability of the frame 1 during wearing. It also makes the frame suitable for users with different head sizes, thus increasing the range of people the frame can be used with.
[0046] Specifically, the frame 1 includes a lens frame 11 and two temples 12. The lens frame 11 is used to mount the lens, and the two temples 12 are arranged opposite to each other and fixedly connected to both ends of the lens frame 11 along its length. Two temples 2 are provided, and the two temples 2 are respectively connected to the two temples 12 through corresponding hinge assemblies 3.
[0047] Optionally, the temple 12 includes opposing inner and outer sidewalls. The inner sidewall of the temple 12 faces the user's face. A first mounting groove 10 is provided at the end of the temple 12 connected to the temple 2. The first mounting groove 10 is a recessed structure formed in the inner sidewall of the temple 12. The temple 2 also includes opposing inner and outer sidewalls. The inner sidewall of the temple 2 faces the user's face. A second mounting groove 20 is provided at the end of the temple 2 connected to the temple 12. The second mounting groove 20 is a recessed structure formed in the inner sidewall of the temple 2. One end of the elastic member 31 extends into the first mounting groove 10, and the other end extends into the second mounting groove 20. The first mounting groove 10 and the second mounting groove 20 can accommodate the elastic member 31, making the structure more compact and aesthetically pleasing.
[0048] like Figure 3 As shown, the temple 2 is provided with a mounting hole 21, which is connected to the second mounting groove 20. The pivot connector 32 can be installed in the mounting hole 21 and is interference-fitted with the mounting hole 21. That is, the pivot connector 32 and the temple 2 are interference-fitted, realizing the detachable connection between the pivot connector 32 and the temple 2. This not only has a simple structure, but also makes it easy to assemble and disassemble the pivot connector 32.
[0049] Specifically, the mounting hole 21 includes a limiting groove 211 and a limiting hole 212. The limiting groove 211 is disposed on the bottom surface of the temple 2. The limiting hole 212 is disposed at the bottom of the limiting groove 211. The limiting hole 212 extends from the bottom of the limiting groove 211 toward the top surface of the temple 2 and communicates with the second mounting groove 20. The limiting hole 212 may or may not penetrate the top surface of the temple 2. In this embodiment, the limiting hole 212 penetrates the top surface of the temple 2.
[0050] like Figure 2 and Figure 4As shown, the rotating shaft connector 32 includes a limiting part 321 and a rotating shaft 322. The limiting part 321 is disposed at one end of the rotating shaft 322 and can be accommodated in the limiting groove 211. The rotating shaft 322 passes through the through hole 3121 and the limiting hole 212, and can rotate relative to the through hole 3121. The limiting part 321 is interference-fitted with the limiting groove 211 and / or the rotating shaft 322 is interference-fitted with the limiting hole 212, thereby realizing the installation of the rotating shaft connector 32 and the interference fit between it and the mounting hole 21. That is, the limiting part 321 is interference-fitted with the limiting groove 211, or the rotating shaft 322 is interference-fitted with the limiting hole 212, or the limiting part 321 is interference-fitted with the limiting groove 211 and the rotating shaft 322 is interference-fitted with the limiting hole 212. All three methods can achieve the interference fit between the rotating shaft connector 32 and the mounting hole 21.
[0051] Optionally, the limiting part 321 is flush with the opening of the limiting groove 211, or is recessed in the limiting groove 211, to prevent the limiting part 321 from protruding from the opening of the limiting groove 211, so that the frame has a more aesthetically pleasing appearance.
[0052] Optionally, the end of the rotating shaft 322 that is not connected to the limiting part 321 passes through the limiting hole 212 and extends out of the limiting hole 212, so as to facilitate the disassembly of the rotating shaft connector 32 through the part of the rotating shaft 322 that extends out of the limiting hole 212.
[0053] Optionally, the rotating shaft 322 is a cylindrical structure with a circular or elliptical cross-section. This structure facilitates relative rotation with the through hole 3121, allowing the temple 2 to open and close smoothly. In this case, the through hole 3121 can be a circular hole. In this embodiment, the cross-section of the cylindrical structure is circular, meaning the rotating shaft 322 is a cylindrical structure and the through hole 3121 is a circular hole.
[0054] like Figure 4 As shown, the rotating shaft 322 includes a first shaft segment 3223, a second shaft segment 3224, and a third shaft segment 3225 connected in sequence. The outer diameter of the second shaft segment 3224 is smaller than the outer diameters of the first shaft segment 3223 and the third shaft segment 3225. A bent portion 312 is fitted onto the second shaft segment 3224, and the height of the bent portion 312 is the same as the height of the second shaft segment 3224. The first shaft segment 3223 and the third shaft segment 3225 limit the bent portion 312 to prevent it from moving arbitrarily along the axial direction of the rotating shaft 322.
[0055] In other embodiments, the circumferential surface of the rotating shaft 322 includes at least one first arcuate surface 3221 and at least one first positioning surface 3222, the first positioning surface 3222 being a plane; the inner surface of the through hole 3121 includes a second positioning surface 3122 and a second arcuate surface 3123, the second positioning surface 3122 being a plane. When the rotating shaft 322 rotates relative to the through hole 3121, the second positioning surface 3122 can be parallel to and opposite to the first positioning surface 3222. When the second positioning surface 3122 is parallel to and opposite to the first positioning surface 3222, it can limit the rotation of the rotating shaft 322, thereby stopping and limiting the temple 2. Figure 5 As shown, the circumferential surface of the second shaft segment 3224 of the rotating shaft 322 includes a first arc-shaped surface 3221 and a first positioning surface 3222. The inner surface of the through hole 3121 includes a second positioning surface 3122 and a second arc-shaped surface 3123. That is, the shape of the through hole 3121 is adapted to the shape of the second shaft segment 3224 of the rotating shaft 322. When the second positioning surface 3122 is parallel to and opposite to the first positioning surface 3222, it can limit the rotation of the rotating shaft 322 to stop and limit the temple 2. When the second arc-shaped surface 3123 is opposite to the first positioning surface 3222, it will not limit the rotation of the rotating shaft 322.
[0056] Optionally, the circumferential surface of the second shaft segment 3224 of the rotating shaft 322 includes a plurality of first arcuate surfaces 3221 and a plurality of first positioning surfaces 3222. The first arcuate surfaces 3221 and the first positioning surfaces 3222 are alternately arranged along the circumference of the rotating shaft 322, and the second positioning surface 3122 can be arranged parallel to and opposite to any of the first positioning surfaces 3222. Figure 6 As shown, the circumferential surface of the second shaft segment 3224 of the rotating shaft 322 includes four first arcuate surfaces 3221 and four first positioning surfaces 3222. The inner surface of the through hole 3121 includes a second positioning surface 3122 and a second arcuate surface 3123. The second arcuate surface 3123 can be parallel to and opposite to any of the first positioning surfaces 3222. When the rotating shaft 322 rotates relative to the through hole 3121, it can play a multiple limiting role, so that the temple 2 stops at multiple angles to meet the different needs of the user. In other embodiments, the number of first arcuate surfaces 3221 and first positioning surfaces 3222 included in the circumferential surface of the second shaft segment 3224 of the rotating shaft 322 is not limited to the above four, but can also be three, five or more.
[0057] Optionally, the limiting part 321 can be a cylindrical structure or a cuboid structure, as long as the lateral dimension of the limiting part 321 is larger than the diameter of the limiting hole 212, so as to play a limiting role.
[0058] Optionally, the elastic element 31 is elastic and capable of elastic deformation. One end of the elastic element 31 is detachably connected to the frame 1 via a fixing member 4. Specifically, one end of the elastic element 31 is provided with at least one fixing hole 3111, and the fixing member 4 passes through the fixing hole 3111 and is connected to the frame 1. In this embodiment, the elastic element 31 has a sheet-like structure, and one end of the elastic element 31 is provided with two fixing holes 3111. The two fixing members 4 pass through the corresponding fixing holes 3111 and are connected to the frame 1 to enhance the connection strength between the elastic element 31 and the frame 1. This connection method is not only firm but also easy to disassemble. The fixing member 4 can be a screw. In other embodiments, the number of fixing holes 3111 is not limited to two, but can also be one, three or more. The elastic element 31 is not limited to a sheet-like structure. It can also be twisted to form a spiral elastic element. The spiral elastic element can have a certain deformation capacity in both the left and right and up and down directions, thereby coping with the uncontrollable deformation of the temple 2 that occurs during daily use, such as when taking off or putting on glasses.
[0059] Optionally, the elastic element 31 can be made of elastic steel or titanium alloy, which has high strength and good elasticity.
[0060] like Figure 2 As shown, the elastic element 31 includes an elastic body 311 and a bent portion 312 connected to the elastic body 311. A through hole 3121 is provided on the bent portion 312. The bent portion 312 is formed by bending the other end of the elastic element 31. This structure is simple and easy to manufacture. In this embodiment, the elastic body 311 and the bent portion 312 are an integral structure.
[0061] Optionally, the second mounting groove 20 includes a first groove 201 and a second groove 202 that are connected. The first groove 201 is located on the side of the second groove 202 near the frame 1. A portion of the elastic body 311 is accommodated in the first groove 201, and the bent portion 312 is accommodated in the second groove 202. The first groove 201 accommodates a portion of the elastic body 311, and the second groove 202 accommodates the bent portion 312, so that the other end of the elastic member 31 can be mounted on the temple 2. Figure 2 As shown, the first groove 201 is a rectangular groove structure that matches the structure of the elastic body 311, and the groove wall of the second groove 202 is an arc-shaped structure that matches the shape of the rotating shaft 322.
[0062] The hinge assembly 3 of this frame has the advantages of good stability, small space occupation and light weight. It not only reduces the width of the temples 2 and makes the appearance more beautiful, but also makes the overall frame lighter and improves the user's wearing comfort.
[0063] This embodiment also provides a smart glasses, including lenses and the aforementioned frame, with the lenses fixed to the frame 1 of the frame. The smart glasses, through the frame 1, can provide a certain clamping force to the user's head, ensuring the stability of the smart glasses during wear.
[0064] It should be noted that the other structures of smart glasses are existing technologies and will not be described in detail here.
[0065] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
