Description

Technical Field

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

[0002] Traditional eyeglasses, with their hinge structure, only allow for freedom of movement in the temples, resulting in a relatively fixed position between the temples and the frame when worn. However, every wearer's facial contours differ; for example, the width between the temples and the height difference between the ears and the bridge of the nose can all affect the comfort of wearing glasses. Furthermore, changes in the wearer's physical condition, such as facial swelling due to staying up late, mean that glasses with a fixed wearing posture are not suitable for changes in the wearer's facial features.

[0003] Existing technology generally overcomes this by setting soft padding on the temples. The soft padding adapts to the deformation of the face and fits the face. However, this method can only adapt in the width direction of the face, and its deformation range is limited by the thickness of the padding, so it can only make small deformations.

[0004] The height difference between the bridge of the nose and the ears can only be adjusted by adjusting the nose pads on the frame. However, since the nose pads are fixed components, they need to be removed with tools each time they are adjusted, which is cumbersome and does not provide the convenience of adjusting them whenever needed.

[0005] Therefore, if the hinge structure of the glasses can be designed to have greater horizontal rotational freedom and rotational freedom in the direction of the height difference between the bridge of the nose and the ears, and apply a force that can keep them in close contact with the face, then the frame and temples can adapt to the wearer's facial contours and adjust their posture to maintain a close fit, without having to deliberately manipulate the glasses or deform them as they are worn. Utility Model Content

[0006] To address the shortcomings of the aforementioned technologies, this invention provides a hinge structure for eyeglasses.

[0007] The technical solution of this utility model is: a hinge structure for eyeglasses, including a frame, lenses, and temples, wherein a post is fixedly or attached to the frame, and the post has a first hinge groove in the horizontal direction.

[0008] The temple includes a hinge end and an ear end facing the frame. The hinge end is provided with a mounting cavity, and a drive mechanism is provided in the mounting cavity. The drive mechanism includes a telescopic housing, a hinge component, a hinge shaft component, a telescopic shaft component, and a return spring.

[0009] The telescopic housing is fixedly connected to the mounting cavity, including a first sliding groove with the opening facing the side of the frame and a travel cavity located at the bottom of the first sliding groove. A limit baffle is provided on the side of the first sliding groove opening relative to the opening and outward flip direction of the temple.

[0010] The hinge component includes a pile head end and a housing end. The pile head end and the housing end are respectively provided with a first hinge hole and a second hinge hole that are perpendicular to each other in the axial direction. The housing end is provided with a second hinge groove in the vertical direction. The pile head end is inserted into the first hinge groove and is connected to the hinge of the pile head component to perform horizontal opening and closing movement of the temple. The cross-sectional shape of the hinge component is adapted to the cross-sectional shape of the first sliding groove.

[0011] The telescopic shaft includes a hinge joint and a shaft. The hinge joint is inserted into the second hinge groove and is hinged to the hinge shaft. The shaft extends into the travel cavity, and a limit flange is provided at the end of the shaft.

[0012] The reset spring is sleeved on the shaft, with one end abutting against the limiting flange and the other end fixed to the stroke cavity. The reset spring drives the telescopic shaft and hinge to retract into the first sliding groove.

[0013] A further feature of this invention is that the telescopic housing has a pin hole that penetrates the travel cavity, and the drive mechanism also includes a pin that passes through the pin hole and intercepts the return spring between the hinge joint and the return spring, thereby restricting the movement of one end of the return spring.

[0014] A further feature of this invention is that the telescopic housing has a rivet indentation between the return spring and the hinge joint, which is embedded in the stroke cavity to restrict the movement of one end of the return spring.

[0015] A further feature of this invention is that the ear loop end is detachably provided with an accessory, which has a horizontal or vertical structure or an arc-shaped structure adapted to the ear contour, and the end face of the accessory that contacts the skin is provided with a soft pad or an elastic pad.

[0016] A further feature of this invention is that the pile head component has a groove at the corresponding limiting baffle, and the end of the groove facing the telescopic housing has a rounded corner.

[0017] The beneficial effects of this invention are as follows: With the driving mechanism between the temples and the headpiece, the frame and temples of the design can move freely in multiple degrees, achieving dynamic adjustment of the frame relative to the temples. When wearing the glasses, the wearer does not need additional adjustments. As the temples are fixed to the ears, the angle between the two temples can expand further according to the width of the face, and the frame can also tilt and flip relative to the height difference of the bridge of the nose to adapt to the facial features of different wearers.

[0018] The specific structure is shown in the attached instruction manual. Figure 2 As shown, in addition to the traditional opening and closing angle, with the cooperation of the limiting baffle and the telescopic shaft, the extension displacement of the telescopic shaft causes the temple to tilt relative to the limiting baffle, thereby allowing the temple to rotate outward at a larger angle to adapt to the wearer.

[0019] Meanwhile, thanks to the design of the hinge and limiting baffle, the hinge can also rotate vertically (i.e., in the direction of the height difference between the bridge of the nose and the ear) as the telescopic shaft moves out of the first sliding groove, as shown in the instruction manual. Figure 6 As shown, adjust the position of the frame between the temples to fit the wearer's face.

[0020] With the return spring design, the return spring compresses and stores force as the shaft and limiting flange displace, continuously driving the telescopic shaft and hinge to move towards the retracted first sliding groove. In this design, when worn, the face pulls the telescopic shaft and hinge out of the first sliding groove, forming a conforming posture. The force of the return spring restoring its deformation drives the telescopic shaft and hinge, which in turn moves the frame and temples back towards the face, maintaining a close fit. This gives the glasses an automatic posture adjustment function as they are worn.

[0021] The force of the return spring can be adjusted according to the wearer's needs. For example, if the wearer prefers a tighter fit to the face to prevent slippage during exercise, the spring tension can be increased. If a looser fit is preferred, the spring tension can be decreased. The glasses can be detachably secured using pins, or secured with riveted grooves to reduce the number of accessories required.

[0022] The soft or elastic padding at the ear loops further enhances the comfort of wearing the glasses. Attached Figure Description

It should be understood that the specific embodiments described herein are only some embodiments of this application, and are only used to explain this application, not to limit this application. It should be noted that, for ease of description, only the parts related to this application are shown in the accompanying drawings. Other related parts can be referred to the general design. In the absence of conflict, the embodiments and technical features in the embodiments of this application can be combined with each other to obtain new embodiments.

[0032] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-6 As shown,

[0033] A hinge structure for eyeglasses includes a frame 1, lenses, and temples 2. A head piece 11 is fixedly disposed or attached to the frame 1, and the head piece 11 is provided with a first hinge groove 12 in the horizontal direction.

[0034] The temple 2 includes a hinge end and an ear end facing the frame 1. The hinge end is provided with a mounting cavity 21. A driving mechanism is provided in the mounting cavity 21. The driving mechanism includes a telescopic housing 3, a hinge component 4, a hinge shaft component 5, a telescopic shaft component 6, and a return spring 7.

[0035] The telescopic housing 3 is fixedly connected to the mounting cavity 21, including a first sliding groove 31 with the groove opening facing the side of the frame 1 and a travel cavity 32 located at the bottom of the first sliding groove 31. A limit baffle 33 is provided on the side of the first sliding groove 31 relative to the opening and outward direction of the temple 2.

[0036] The hinge component 4 includes a pile head end 41 and a housing end. The pile head end 41 and the housing end are respectively provided with a first hinge hole 42 and a second hinge hole 43 that are perpendicular to each other in the axial direction. The housing end is provided with a second hinge groove 44 in the vertical direction. The pile head end 41 is inserted into the first hinge groove 12 and is connected to the pile head component 11 in a hinge connection that allows the temple 2 to open and close in the horizontal direction. The cross-sectional shape of the hinge component 4 is adapted to the cross-sectional shape of the first sliding groove 31.

[0037] The telescopic shaft 6 includes a hinge joint 61 and a shaft 62. The hinge joint 61 is inserted into the second hinge groove 44 and is hinged to the hinge shaft 5. The shaft 62 extends into the stroke cavity 32, and a limiting flange 63 is provided at the end of the shaft 62.

[0038] The reset spring 7 is sleeved on the shaft 62, with one end abutting against the limiting flange 63 and the other end fixed to the stroke cavity 32. The reset spring 7 drives the telescopic shaft 6 and the hinge 4 to retract into the first sliding groove 31.

[0039] The telescopic housing 3 is provided with a pin hole 34 that passes through the travel cavity 32. The drive mechanism also includes a pin that passes through the pin hole 34 and intercepts the return spring 7 between the hinge joint 61, thus restricting the movement of one end of the return spring 7.

[0040] The telescopic housing 3 has a rivet indentation between the return spring 7 and the hinge joint 61. The rivet indentation is embedded in the stroke cavity 32, which restricts the movement of one end of the return spring 7.

[0041] The ear loop end is detachably equipped with an accessory, which has a horizontal or arc-shaped structure that conforms to the contour of the ear. The end face of the accessory that contacts the skin is provided with a soft or elastic pad.

[0042] The pile head component 11 is provided with a groove 111 at the corresponding limiting baffle 33, and the end of the groove 111 facing the telescopic housing 3 is provided with a rounded corner.

[0043] With the driving mechanism between the temples 2 and the headpiece 11, the frame 1 designed in this application can move with multiple degrees of freedom relative to the temples 2, realizing dynamic adjustment of the frame 1 relative to the temples 2. When wearing glasses, the wearer does not need to make additional adjustments. As the temples 2 are fixed on the ears, the angle between the two temples 2 can expand further according to the width of the face, and the frame 1 can also tilt and flip relative to the height difference of the bridge of the nose to adapt to the facial features of different wearers.

[0044] The specific structure is shown in the attached instruction manual. Figure 2As shown, in addition to the traditional opening and closing angle, with the cooperation of the limiting baffle 33 and the telescopic shaft 6, the extension displacement of the telescopic shaft 6 allows the head piece 11 to tilt relative to the limiting baffle 33, thereby enabling the temple 2 to rotate outward at a larger angle to adapt to the wearer.

[0045] Meanwhile, with the design of the hinge component 4 and the limiting baffle 33, the hinge component 4 can also rotate vertically (i.e., in the direction of the height difference between the bridge of the nose and the ear) while the telescopic shaft component 6 moves out of the first sliding groove 31, as shown in the instruction manual. Figure 6 As shown, adjust the position of the frame 1 between the temples 2 to fit the wearer's face.

[0046] With the design of the return spring 7, the return spring 7 compresses and stores force as the shaft 62 and the limiting flange 63 move, continuously driving the telescopic shaft 6 and the hinge 4 to move towards the retracted first sliding groove 31. With this design, when worn, the face pulls the telescopic shaft 6 and the hinge 4 out of the first sliding groove 31, forming a conforming posture. The force of the return spring 7 restoring its deformation drives the telescopic shaft 6 and the hinge 4, which in turn drives the frame 1 and the temples 2 to retract towards the face, thus maintaining a close fit to the facial contours. In this way, the glasses automatically adjust their posture as worn.

[0047] The force of the return spring 7 can be adjusted according to the wearer's needs. For example, if the wearer prefers a tighter fit to the face to prevent slippage during exercise, the spring tension can be increased. If a looser fit is preferred, the spring tension can be decreased. The glasses can be detachably secured using a pin, or secured using riveted grooves to reduce the number of accessories required.

[0048] The soft or elastic padding at the ear loops further enhances the comfort of wearing the glasses.

[0049] The technical solution of this application has been described in conjunction with the preferred embodiments shown in the accompanying drawings. Those skilled in the art should understand that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
