Description

Technical Field

[0001] This utility model relates to the field of eyeglasses outward-turning buffer hinge technology, and in particular to an eyeglasses outward-turning buffer hinge. Background Technology

[0002] As a common accessory for correcting vision, protecting the eyes, or enhancing facial aesthetics, eyeglasses' structural stability and durability directly impact the user experience. Among these components, the hinge, a crucial mechanical part connecting the temples to the frame, is essential for the flexible opening and closing of the temples. It must ensure the glasses are stably secured to the user's head while also facilitating folding and storage when not in use, making it a vital element determining the overall performance of the eyeglasses.

[0003] Currently, the hinges widely used in the market still generally adopt the traditional rigid connection structure. Although this design is simple, when faced with external impacts, excessive use, or improper operation, stress concentration can easily occur in the hinge area, leading to excessive wear, deformation, or breakage of the hinge components. It may even cause damage to the overall structure of the frame and temples. This not only affects the normal use of the glasses and increases the product failure rate, but also seriously affects consumer satisfaction. Utility Model Content

[0004] Based on this, the present invention provides an outward-folding buffer hinge for eyeglasses, which has a simple structure and is easy to use. The temple is slidably connected to the movable support via a sliding key. When the movable support rotates with interference, the temple can fold outward at a certain angle, forming an elastic buffer structure. This avoids the situation where the traditional rigid connection structure directly deforms or breaks under external force, effectively reducing the risk of damage to the eyeglasses hinge, extending the service life of the eyeglasses, and greatly improving the user's wearing experience and satisfaction.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] Please see Figures 1 to 7 The above is an embodiment of the eyeglasses outward-turning buffer hinge, which includes a folding component 10 and a buffer component 20 slidably connected to one end of the folding component 10.

[0018] The folding assembly 10 includes a fixed bracket 11 and a movable bracket 12 that is hinged to the fixed bracket 11. Wherein, as... Figure 1As shown, the fixed bracket 11 is used to connect the frame 30, the movable bracket 12 is used to connect the buffer assembly 20, and the buffer assembly 20 is used to connect the temple 40, thereby realizing that the temple 40 can be folded to connect to the frame 30.

[0019] The movable bracket 12 has protrusions 13 on opposite sides of its outer surface away from the fixed bracket 11. Each protrusion 13 has a groove 14 on its inner surface and a limiting piece 15 is connected to the inner side of each protrusion 13 corresponding to the groove 14.

[0020] The buffer assembly 20 includes a sliding key 21 that is slidably connected to the movable support 12, a baffle 22 that is fixedly connected to one end of the sliding key 21, and an elastic element 23 installed inside the sliding key 21.

[0021] Specifically, the sliding key 21 includes a base 211, an inner side plate 212 connected to the inside of the base 211, an outer side plate 213 connected to the outside of the base plate 211, and slide rail portions 214 extending outward from opposite sides of the outer side plate 213; a baffle 22 is mounted on the end of the outer side plate 213 away from the base 211. The slide rail portion 214 is fitted into the interior of the slide groove 14 to achieve a sliding connection between the sliding key 21 and the movable support 12.

[0022] Specifically, in this embodiment, the inner side plate 212 and the outer side plate 213 are spaced apart, and the space between the inner side plate 212 and the outer side plate 213 is used to accommodate the installation of the elastic member 23; two limiting pieces 15 are engaged between the inner side plate 212 and the outer side plate 213, and the limiting pieces 15 are used to abut against the end of the elastic member 23 away from the base 211.

[0023] In this embodiment, the elastic element 23 is a spring sheet arranged in a "Z" shape.

[0024] In this embodiment, the width of the base 211 is greater than the width of the outer plate 213, and the two opposite ends of the base 211 protrude beyond the outer surface of the slide rail 214, so that the limiting piece 15 is located between the base 211 and the baffle 22, thereby effectively limiting the relative sliding stroke of the sliding key 21 and the movable bracket 12.

[0025] Furthermore, in this embodiment, the end of the base 211 facing away from the baffle 22 is also provided with an internal threaded hole 215. By the cooperation of the screw 216 with the internal threaded hole 215, the buffer assembly 20 can be installed on the temple 40.

[0026] Specifically, such as Figure 2 and Figure 3As shown, the temple 40 includes a temple outer shell 41 and a temple inner shell 42 that matches and connects to the temple outer shell 41. The temple outer shell 41 has a positioning cavity 43 on its inner side, and a through hole 44 at one end of the temple outer shell 41 corresponding to the positioning cavity 43. The through hole 44 corresponds one-to-one with the internal threaded hole 215. During assembly, the buffer assembly 20 is placed inside the positioning cavity 43, and a screw 216 is used to pass through the through hole 44 and connect to the internal threaded hole 215 to achieve a fixed connection between the sliding key 21 and the temple outer shell 41. This securely installs the buffer assembly 20 inside the temple outer shell 41. Finally, the temple inner shell 42 is matched and connected to the temple outer shell 41, thus completing the assembly of the eyeglasses' outward-facing buffer hinge and the temple 40.

[0027] like Figure 1 The figure shown is a three-dimensional schematic diagram of the eyeglasses outward-folding buffer hinge of this utility model in the normal open state of the temple, wherein the end face of the temple 40 is matched and fixed to the bracket 11.

[0028] like Figure 7 The diagram shows a three-dimensional view of the eyeglasses outward-folding buffer hinge of this invention in the outward-folding state of the temple. Under the outward-folding force, the outer side of the end face of the temple 40 abuts against the fixed bracket 11. The temple 40 rotates outward at a certain angle along this abutment position, forming a gap between the temple 40 and the fixed bracket 11. At this time, since the sliding key 21 is fixed to the temple shell 41, the movable bracket 12 continues to rotate with interference and move closer to the fixed bracket 11. During this process, the movable bracket 12 and the sliding key 21 slide relative to each other, that is, the temple 40 slides away from the frame 30 to prevent rigid damage. At this time, the elastic element 23 is in a compressed state. When the external force is removed, the elastic element 23 returns to its original state, causing the temple 40 to automatically return to its original position. Figure 1 The position of the temple in its normal open state is shown, that is, the end face of the temple 40 is matched and fixed to the bracket 11.

[0029] The aforementioned eyeglasses outward-folding buffer hinge has a simple structure and is easy to use. The temple 40 is slidably connected to the movable support 12 via the sliding key 21. When the movable support 12 rotates with interference, the temple 40 can fold outward at a certain angle, forming an elastic buffer structure. This avoids the situation where the traditional rigid connection structure directly deforms or breaks under external force, effectively reducing the risk of damage to the eyeglasses hinge, extending the service life of the eyeglasses, and greatly improving the user's wearing experience and satisfaction.

[0030] 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.

[0031] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, 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.
