Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to eyeglasses. Background Technology

[0002] Currently, eyeglass frames on the market generally consist of a frame and temples, connected by hinges. Traditional eyeglass hinge designs are rather rigid, which can cause pressure on the ears during prolonged wear. Spring hinges, on the other hand, are more ergonomic, offering elasticity and cushioning. They can be fine-tuned to fit the wearer's head and ear shape, reducing pressure and making them more comfortable. Spring hinges also allow the temples to deflect outwards at a greater angle.

[0003] Patent CN203133415U discloses a connection structure between an eyeglass temple and an eyeglass frame, including a post fixed to the eyeglass frame, with an eyeglass temple connecting hinge with a locking fitting at the end of the post; and a locking groove fixedly disposed on the inner side of the eyeglass temple and detachably and slidably engaging with the locking fitting. The eyeglass temple connecting hinge includes: a U-shaped rotating member, the open end of which is hinged to the end of the post; a spring return member, comprising a spring body and a top block fixedly disposed at one end of the spring body, one end of which abuts against the positioning surface of the guide block, and the other end pressing against the closed end of the U-shaped rotating member, wherein the surface of the top block in contact with the positioning surface is an inclined surface that allows the spring return member to be further compressed when the eyeglass temple is moved outwards from the eyeglass frame; and a hinge housing, which can fit the U-shaped rotating member and the spring return member into its receiving cavity, the hinge housing constituting the locking fitting.

[0004] The spring hinges in the above-mentioned structure can provide force cushioning to prevent damage when the temples are opened. However, for glasses that require lightweight design, such as Bluetooth glasses (which house Bluetooth communication modules, batteries, and speakers in the temples), plastic is usually used for the temples to avoid excessive weight affecting wearing comfort. When the temples are opened outward under force, the end face of the temples is pressed against its hinge point (post) on the frame. Long-term and frequent compression can easily cause the end face of the temples to crack, and may even cause the components mounted on the temples to lose their stable mounting position, affecting the structural reliability. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a pair of eyeglasses. The technical problem this utility model aims to solve is that the reliability of the existing eyeglass temple hinge structure is insufficient.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An eyeglass includes temples, a flexible hinge head, and a hinge portion located on the frame. The temples are made of plastic. The flexible hinge head includes a strip-shaped housing and a rod-shaped movable core that can move axially relative to the housing. The housing is made of metal. One end of the movable core extends out of the housing and is hinged to the hinge portion. The temple has a receiving groove at its end. One end of the housing is fixed in the receiving groove via a connector. The other end of the housing is integrally connected to a limiting protrusion. The limiting protrusion protrudes from the end face of the temple and is located outside the movable core. When the temple opens outward and moves the movable core outward from the housing, only the limiting protrusion abuts against the hinge portion.

[0008] By creating a receiving groove at the end of the plastic temple, the metal shell of the elastic hinge head is fixed within the receiving groove via a connector, achieving a stable connection between different materials. Simultaneously, a limiting protrusion is provided at the other end of the shell, located outside the movable core. When the temple opens and the movable core moves outward along the shell's axis, the limiting protrusion abuts against the hinge. This abutting position of the limiting protrusion and the hinge serves as a limiting fulcrum, allowing the stressed temple to swing outward and open. At this time, the movable core can be pulled outward and provides clamping force to ensure stable wearing. Because the pressing force is concentrated on the limiting protrusion of the shell, it prevents the end of the plastic temple from being directly subjected to rigid contact and resulting in crushing damage due to long-term large localized compressive force. This ensures that the installation state of the elastic hinge head installed at the temple end remains unaffected, improving the structural reliability.

[0009] In the aforementioned eyeglasses, the limiting protrusion is in the shape of a vertical plate, with one side of the limiting protrusion facing and abutting against the hinge portion. This increases the contact area between the limiting protrusion and the hinge portion, preventing excessive pressure at the contact point from causing deformation damage to the limiting protrusion or the hinge portion, thereby ensuring the structural reliability of the limiting structure and the hinge structure.

[0010] In the aforementioned eyeglasses, the edge of the limiting protrusion opposite the hinge is rounded. This allows the edge of the limiting protrusion to slide off the hinge surface with less frictional resistance when the temple moves, resulting in smoother and more fluid movement, preventing scratches and damage to the hinge, and ensuring structural reliability.

[0011] In the aforementioned eyeglasses, the receiving groove is formed on the end face of the temple, and the connector is a screw that is screwed through the circumferential side of the temple. The inner end of the connector is located within the receiving groove and abuts against or is fixed to the housing. This allows the screw to easily tighten or lock the housing within the receiving groove, preventing the housing from coming out and ensuring structural reliability. Even if the elastic hinge head needs maintenance or replacement due to damage to the limiting protrusion, disassembly can be easily achieved by loosening and removing the screw without affecting the temple structure, ensuring reliable subsequent use. Alternatively, the connector can be a rivet or fastening pin to fix the housing to the temple, ensuring stability.

[0012] In the aforementioned eyeglasses, the connector is vertically positioned and attached to the lower side of the temple. This conceals the screw in an area not easily noticed by the eye, ensuring an aesthetically pleasing appearance and preventing the screw from easily coming loose due to user touch.

[0013] In the aforementioned eyeglasses, the receiving groove is open towards the inside of the temple, and part of the housing extends inward from the receiving groove. This allows the housing to fully utilize the space inside the temple, reducing the requirements for the size and material of the temple.

[0014] In the aforementioned eyeglasses, the cross-sectional shape of the receiving groove is T-shaped, and the cross-sectional shape of the housing matches the cross-sectional shape of the receiving groove. This facilitates effective containment of the housing embedded in the receiving groove along the inner and outer directions of the temple, preventing the housing from coming out due to the opening of the receiving groove on the inner side of the temple, thus ensuring structural reliability.

[0015] In the aforementioned eyeglasses, the hinge is made of metal. This helps ensure the structural strength of the hinge, preventing it from being easily damaged or deformed under pressure, and ensuring structural reliability.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] This pair of glasses features a limiting protrusion on the elastic hinge head that abuts against the hinge when the temples are opened under pressure. This concentrates the pressing force onto the limiting protrusion on the housing, preventing the plastic temple end face from being subjected to localized pressure and causing cracking damage. As a result, the installation position of the elastic hinge head at the end of the temple is not affected, effectively ensuring the structural reliability of the glasses as Bluetooth glasses.

[0027] 4. Connectors. Detailed Implementation

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] like Figure 1-6As shown, the glasses include two temples 1, two elastic hinge heads 2, and two hinge portions 31 located at both ends of the metal frame 3. The temples 1 are made of plastic. The hinge portions 31 are L-shaped. The elastic hinge head 2 includes a strip-shaped housing 21 and a rod-shaped movable core 22. The elastic fit structure between the movable core 22 and the housing 21 is prior art. One end of the housing 21 is embedded and fixed to the end of the temple 1 through a connector 4. The temple 1 is made of plastic. The movable core 22 extends out of the other end of the housing 21 and is hinged to the hinge portion 31 by existing screws. The other end of the housing 21 has a limiting protrusion 211. The limiting protrusion 211 protrudes from the end face of the temple 1. The limiting protrusion 211 is located outside the movable core 22. When the temple 1 opens outward and drives the movable core 22 to move outward, the limiting protrusion 211 abuts against the hinge portion 31. Specifically, both the housing 21 and the hinge portion 31 are made of metal. The limiting protrusion 211 is vertically plate-shaped, with one side of the limiting protrusion 211 facing and abutting against the hinge portion 31. The edge of the side of the limiting protrusion 211 facing the hinge portion 31 is rounded. The end face of the temple 1 has a receiving groove 11. One end of the housing 21 is inserted into the receiving groove 11. The connector 4 is a screw that is screwed through the circumferential side of the temple 1. The inner end of the connector 4 is located in the receiving groove 11 and abuts or is fixed to the housing 21. Preferably, the connector 4 is vertically arranged and connected to the lower side of the temple 1. The receiving groove 11 is opened on the inner side of the temple 1 and extends to the end face of the temple 1. Part of the housing 21 extends inward into the receiving groove 11. The cross-sectional shape of the receiving groove 11 is T-shaped, and the cross-sectional shape of the housing 21 is adapted to the cross-sectional shape of the receiving groove 11.

[0030] When the temple 1 is in its naturally open state, the movable core 22 pulls the hinge 3 tight. At this time, the end face of the housing 21 and the limiting protrusion 211 are in contact with and abut against the hinge 3. When the temple 1 is subjected to force and opens further outward, the entire temple 1 swings around the side of the limiting protrusion 211 opposite to the hinge 3 as the fulcrum. At the same time, the movable core 22 is pulled and moves outward from the housing 21. Only the limiting protrusion 211, which is made of metal, is in contact with the hinge 3, thus preventing the plastic temple 1 from being directly compressed and cracked.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
