Technical Field

[0001] This invention relates to the field of eyewear technology, and in particular to an eyeglass and its tilt-forward adjustment mechanism, which can be used in smart glasses, AR glasses, VR glasses, functional goggles, or sports glasses, etc. Background Technology

[0002] The tilt angle of eyeglasses is a key parameter affecting wearing comfort and visual experience. Different face shapes, nose heights, and usage scenarios (such as reading, sports, and using head-mounted display devices) have different requirements for the tilt angle of eyeglasses.

[0003] Currently, many glasses have a fixed tilt angle, meaning they cannot be actively adjusted according to the user's needs. This leads to problems such as the frames slipping down, the fit being too tight or too loose, and the line of sight shifting for some users. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides eyeglasses and their tilt-forward adjustment mechanism, which can accurately and stably adjust the tilt-forward angle of the temples relative to the frame, thereby improving wearing comfort and optical adaptability.

[0005] To achieve the above objectives, the technical solution provided by the present invention is as follows: This invention provides a tilt-forward adjustment mechanism for eyeglasses, including a limiting member, a first rotating support member for connecting to the frame, a second rotating support member for connecting to the temple, and a rotating connector connecting the first and second rotating supports. The rotating connector has a rotating portion and a mounting portion connected to each other. The rotating portion is rotatably connected to the first rotating support member, and the mounting portion is rotatably mounted to the second rotating support member. The rotation trajectory of the rotating portion relative to the first rotating support member intersects the rotation trajectory of the mounting portion relative to the second rotating support member. The limiting member is used to restrict the mounting portion to the second rotating support member to lock the relative rotation angle between the mounting portion and the second rotating support member, thereby achieving active adjustment of the tilt-forward angle of the eyeglasses.

[0006] Furthermore, the second rotating support is a nut seat with an internally threaded post, the mounting part has a through mounting hole, and the mounting part is rotatably sleeved on the internally threaded post through the mounting hole; the limiting member is movably inserted through the mounting hole and threadedly connected to the internally threaded post, so that the limiting member, the mounting part and the nut seat are integrally connected.

[0007] Furthermore, the limiting component is a locking screw, and the locking screw is a CD-pattern Torx screw.

[0008] Furthermore, it also includes a hinge shaft; the first rotating support has two support arms arranged at a relative distance, both support arms are provided with a first hinge hole, and the rotating part is provided with a second hinge hole; the rotating part is rotatably inserted between the two support arms, and the hinge shaft passes through the first hinge hole and the second hinge hole, so that the rotating part is pivotally connected to the two support arms.

[0009] Furthermore, a pivot groove is provided between the two support arms; the rotating part is rotatably inserted into the pivot groove; the outer peripheral surface of the rotating part has an arc-shaped surface and a stop surface, and when the rotating part rotates in the pivot groove, only the stop surface can abut against the bottom of the pivot groove to limit the rotation range of the rotating part.

[0010] Furthermore, the rotation trajectory of the rotating part relative to the first rotating support member is perpendicular to the rotation trajectory of the mounting part relative to the second rotating support member.

[0011] The present invention provides eyeglasses, including lenses, frames, temples, and the aforementioned tilt adjustment mechanism; a first rotating support member of the tilt adjustment mechanism is connected to the frames; and a second rotating support member of the tilt adjustment mechanism is connected to the temples.

[0012] Furthermore, the first rotating support is detachably assembled to the frame; the second rotating support is integrally formed inside the temple; a clearance groove for exposing the second rotating support is provided on the side of the temple near the rotating connector of the tilt-forward adjustment mechanism, and the mounting part of the tilt-forward adjustment mechanism is movably inserted into the clearance groove.

[0013] Furthermore, the outer peripheral surface of the mounting part of the tilt-forward adjustment mechanism is provided with an outwardly protruding limiting tooth, and the side of the temple near the rotating connector is provided with a limiting groove communicating with the clearance groove; the limiting tooth is rotatably mounted in the limiting groove, and the limiting tooth is limited by the two opposite groove walls of the limiting groove to limit the tilt-forward adjustment range of the glasses; and / or, the end of the second rotating support opposite to the rotating connector is provided with an inverted buckle structure for reinforcing the connection of the temple.

[0014] Furthermore, the rotation angle range of the limiting tooth within the limiting groove is ±5 degrees.

[0015] The technical solution provided by this invention has the following beneficial effects: By rotatably assembling the mounting part of the rotating connector to the second rotating support, and the rotation trajectory of the rotating part of the rotating connector relative to the first rotating support intersects the rotation trajectory of the mounting part relative to the second rotating support, the relative rotation angle between the mounting part and the second rotating support can be adjusted first, and then locked by the cooperation of the limiting member, so as to achieve active, precise and stable adjustment of the tilt angle of the glasses, thereby improving wearing comfort and optical adaptability.

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 4 This embodiment provides a pair of glasses, including as follows: Figure 4 The lens 100, frame 200, temples 300 (made of plastic), and tilt adjustment mechanism (hereinafter referred to as tilt adjustment mechanism 400) shown herein, wherein, as Figure 1 and Figure 2 The tilt adjustment mechanism 400 shown includes a limiting member 4, a first rotating support member 1 connected to the frame 200, a second rotating support member 2 connected to the temple 300, and a rotating connector 3 connecting the first rotating support member 1 and the second rotating support member 2. The first rotation trajectory of the rotating connector 3 relative to the first rotating support member 1 is perpendicularly intersected by the second rotation trajectory of the rotating connector 3 relative to the second rotating support member 2. Of course, in other embodiments, the first rotation trajectory may also be obliquely intersected by the second rotation trajectory.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the first end of the first rotating support 1 is detachably assembled to the frame 200, and the second rotating support 2 is integrally injection molded into the temple 300. The temple 300 has a relief groove 6 on the side near the rotating connector 3 for exposing the second rotating support 2.

[0021] In this embodiment, the rotating connector 3 has a rotating part 31 and a mounting part 32 connected to each other. The rotating part 31 is rotatably connected to the second end of the first rotating support 1 away from the mirror frame 200. The mounting part 32 is movably inserted into the relief groove 6 and rotatably assembled to the second rotating support 2.

[0022] In practice, the limiting component 4 is a locking screw, and the second rotating support component 2 is a nut seat with an internally threaded post 21.

[0023] The mounting part 32 has mounting holes 321 penetrating its left and right surfaces. The mounting part 32 is rotatably sleeved on the internal threaded post 21 through the mounting holes 321. At this time, the side of the mounting part 32 facing the second rotating support 2 and the side of the second rotating support 2 facing the mounting part 32 are relatively rotatable mating surfaces.

[0024] Furthermore, the first rotating support 1 has two support arms 11 arranged at a relative distance, a pivot groove 12 is provided between the two support arms 11, and each of the two support arms 11 is provided with a first hinge hole 111. The center of the rotating part 31 is provided with a second hinge hole 311. The rotating part 31 is rotatably inserted into the pivot groove 12, and the second hinge hole 311 of the rotating part 31 and the first hinge holes 111 of the two support arms 11 are connected by a hinge shaft 5, that is, the hinge shaft 5 passes through the first hinge hole 111 and the second hinge hole 311, so that the rotating part 31 is pivotally connected to the two support arms 11.

[0025] When it is necessary to adjust the tilt angle of the glasses, first rotate the temple 300 in the upper and lower vertical planes, and simultaneously drive the second rotating support 2 to rotate relative to the rotating connector 3 in the same vertical plane until a suitable tilt angle is achieved. Then, the limiting member 4 is movably inserted into the mounting hole 321 and threadedly locked to the internal thread post 21, so that the limiting member 4, the mounting part 32 and the second rotating support 2 form an integral connection. That is, through the cooperation of the limiting member 4, the mounting part 32 is restricted on the second rotating support 2 to lock the relative rotation angle between the mounting part 32 and the second rotating support 2, thus realizing the active adjustment of the tilt angle of the glasses.

[0026] When it is necessary to fold or unfold the glasses, the temple 300 can be rotated in the left and right horizontal planes, and the temple 300 can be unfolded or folded through the pivot connection between the rotating part 31 and the two support arms 11 of the first rotating support member 1.

[0027] In summary, by rotatably assembling the mounting part 32 of the rotating connector 3 to the second rotating support 2, and with the rotating part 31 of the rotating connector 3 perpendicularly intersecting the first rotation trajectory of the first rotating support 1 with the second rotation trajectory of the mounting part 32 relative to the second rotating support 2, the relative rotation angle between the mounting part 32 and the second rotating support 2 can be adjusted first, and then locked by the cooperation of the limiting member 4, so as to achieve active, precise and stable adjustment of the tilt angle of the glasses, thereby improving wearing comfort and optical adaptability.

[0028] In addition, by fixing the second rotating support 2 inside the plastic temple 300 through integral injection molding, it can be ensured that the second rotating support 2 is accurately fixed in the temple 300 and is firmly connected, and can withstand repeated locking torque without loosening or falling out.

[0029] Of course, in other embodiments, the temple 300 can also be made of metal, and the second rotating support 2 can also be fixed to the temple 300 by welding or screwing. The first rotating support 1 can also be an integral structure with the frame 200 or be an integrally connected structure that cannot be detached.

[0030] Further preferred, such as Figure 2 and Figure 3 As shown, the outer peripheral surface of the mounting part 32 is provided with an outwardly protruding limiting tooth 322, and the temple 300 is provided with a limiting groove 61 that communicates with the relief groove 6 on the side near the rotating connector 3. The limiting tooth 322 is rotatably mounted in the limiting groove 61. The limiting tooth 322 is restricted by the two opposite groove walls of the limiting groove 61 to limit the adjustment range of the tilt angle of the glasses. The rotation angle range of the limiting tooth 322 in the limiting groove 61 is ±5 degrees, which is the adjustment range of the tilt angle. Therefore, the precise adjustment of the tilt angle can be further realized.

[0031] Further preferably, the limiting component 4 is a CD-patterned Torx screw, which can achieve high torque transmission, anti-slippage, and fit for precise fastening assembly.

[0032] Further preferred, such as Figure 2 and Figure 3As shown, the outer peripheral surface of the rotating part 31 has an arc-shaped surface 312 and a stop surface 313. When the rotating part 31 rotates within the pivot groove 12, only the stop surface 313 can abut against the bottom of the pivot groove 12 to limit the rotation range of the rotating part 31, and also limit the maximum unfolding range of the temple 300. Of course, the arc-shaped surface 312 is used to cooperate with its rotation within the pivot groove 12, and the arc-shaped surface 312 will not cause mechanical interference during the rotation process.

[0033] Further preferred, such as Figure 2 and Figure 3 As shown, the second rotating support 2 is provided with an undercut structure 22 at one end away from the internal threaded post 21. When the second rotating support 2 is integrally injection molded into the temple 300, the undercut structure 22 further achieves a firm connection between the second rotating support 2 and the temple 300, and can withstand repeated locking torque without loosening or falling out.

[0034] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
