Abstract
Description
Technical Field
[0001] This invention relates to the field of sports eyewear technology, specifically, to a type of sports eyewear based on a magnetic connection method. Background Technology
[0002] Currently, most rimless sports glasses use lens cutting and structural clips to fix the lenses to the temples, which cannot meet users' needs for quick and convenient lens replacement outdoors. The clip-on design of most rimless sports glasses also leaves users unsure whether they can replace the lenses themselves. PC material lenses are relatively soft and prone to scratches, causing users to hesitate when replacing them.
[0003] Moreover, most frameless sports glasses currently use a buckle design, which may cause the glasses to come out of the correct position after a high-speed cycling accident, resulting in the lenses cutting the face.
[0004] With the increasing demand for personalization in the market, personalized consumption is gradually becoming the mainstream. The ability to easily replace personalized accessories will become an important direction for product design. Therefore, it is necessary to meet the demand for quick and easy replacement of lens components and temple components, and to ensure that the above-mentioned parts can meet the product usage requirements and provide a better wearing experience. Moreover, for safety reasons, it is also necessary to prevent the glasses from falling out of the correct position and the lenses from cutting the face after a high-speed cycling accident. Summary of the Invention
[0005] The purpose of this invention is to provide a magnetic connection structure and sports glasses that, while ensuring normal wear, prevents the lenses from cutting the face when the glasses fall out of their correct position during a high-speed cycling accident. It also allows for quick and convenient replacement of lens and temple components, and ensures that these components meet product usage requirements and provide a better wearing experience.
[0006] The object of this invention is achieved as follows: a magnetic connection structure for detachably connecting a lens to a temple, comprising:
[0007] An inner seat connected to the temple, wherein the inner seat is positioned and engaged with the inner side of the lens;
[0008] Outer seat, which is positioned and engaged with the outer side of the lens;
[0009] The inner and outer seats are respectively fixed with an inner magnet and an outer magnet. When the outer magnet and the inner magnet are attracted together, the outer magnet inserts a lens and directly contacts the inner magnet. The outer and inner seats clamp the lens together and can be separated.
[0010] Furthermore, the structure also includes a fitting hole in the lens, through which the outer magnet passes and forms surface contact with the inner magnet.
[0011] Furthermore, the inner seat is provided with at least two forward-protruding, breakable positioning protrusions that can break apart in the event of a violent impact to the eyeglasses. The breakable positioning protrusions are positioned and engaged with the side of the lens and the outer seat.
[0012] Furthermore, the outer seat has at least two outer positioning grooves that correspond one-to-one with the breakable positioning protrusions, and the lens side has a mirror side positioning groove that is the same number as the outer positioning grooves and corresponds one-to-one with them. The breakable positioning protrusions are inserted into the corresponding mirror side positioning grooves and the corresponding outer positioning grooves.
[0013] Furthermore, the breakable positioning protrusion is generally L-shaped, with one part of the breakable positioning protrusion fitting into the lens-side positioning groove, and the other part fitting into the outer positioning groove and abutting against the outer side of the lens.
[0014] Furthermore, the surface of the outer seat that contacts the outer side of the lens is a curved surface that matches the outer surface of the lens, and the surface of the inner seat that contacts the inner side of the lens is a curved surface that matches the inner surface of the lens.
[0015] Furthermore, the outer seat has at least two outer locking pins integrally provided on the surface that fits against the outer side of the lens, and the inner seat has at least two pin positioning holes on the surface that fits against the inner side of the lens. The outer locking pins pass through the lens positioning holes of the lens and are inserted into the pin positioning holes one by one.
[0016] Furthermore, the inner magnet and the outer magnet are respectively detachably fixed to the mounting groove of the inner seat and the mounting groove of the outer seat.
[0017] As another aspect of the present invention, a sports glasses is proposed, which includes a lens and two temples, and further includes two magnetic connection structures, which are respectively connected to the two temples and also respectively connected to the left and right sides of the lens.
[0018] Furthermore, at least one of the temples is detachably fitted with a contact pad that contacts the head. The contact pad is made of a thermoplastic elastic material, and the contact surface of the contact pad has a plurality of inner contact protrusions.
[0019] The beneficial effects of this invention are as follows:
[0020] It can meet the need for quick and convenient replacement of lens components and temple components, and enable the above parts to meet the product usage requirements and provide a better wearing experience;
[0021] This ensures that, assuming the glasses can be worn properly, they can prevent the lenses from cutting the face if the glasses fall out of the correct position after a high-speed cycling accident.
[0022] Each magnetic connection structure can be separated under force, allowing it to be in a detached state when the user replaces it. This enables quick and non-destructive replacement of different personalized lenses or compatibility with different temple shapes, reducing the difficulty of installing personalized accessories. It can also be quickly separated in the event of a violent impact (such as in the case of a high-speed cycling crash). The inner and outer mounts can be quickly separated from the lens to prevent the lens from cutting the face.
[0023] Because the inner and outer magnets are detachable, different grades of magnetic components can be replaced to meet different collision breaking torques and thus meet the safety requirements of different movements.
[0024] The present invention has a simple structure and is firmly installed, which can reduce the difficulty of applying this structure in different product models. Attached Figure Description

Detailed Implementation
[0032] The following will refer to the appendices in the embodiments of the present invention. Figure 1-6 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0033] like Figure 1-2As shown, a frameless sports glasses is proposed, which includes a lens 7 and two temples 4, and also includes two magnetic connection structures, which are respectively connected to the two temples 4 and to the left and right sides of the lens 7.
[0034] Each magnetic connection structure includes:
[0035] The inner seat 1 is connected to the temple 4, and the inner seat 1 is positioned and engaged with the inner side of the lens 7.
[0036] Outer seat 5, the outer seat 5 is positioned and fitted with the outer side of lens 7.
[0037] The inner seat 1 and the outer seat 5 are respectively fixedly installed with an inner magnet 3 and an outer magnet 6. Correspondingly, the inner seat 1 and the outer seat 5 can be provided with corresponding mounting grooves to position their respective magnets. When the outer magnet 6 and the inner magnet 3 are attracted to each other, the outer magnet 6 can be inserted into the lens 7 and directly contact the inner magnet 3. The relative positions of the outer seat 5 and the inner seat 1 can be fixed at the same time, thereby clamping the lens 7 from the inside and outside. The outer seat 5 and the inner seat 1 can be separated, making it very convenient to assemble and replace parts.
[0038] The sports glasses of this embodiment can meet the need for quick and convenient replacement of lens components and temple components, and enable the above-mentioned parts to meet the product usage requirements and provide a better wearing experience.
[0039] Each magnetic connection structure can be separated under force, and can be in a separated state when the user replaces it; it can also be separated quickly when subjected to a violent impact (such as in the case of a high-speed cycling crash). The inner magnet 3 and the outer magnet 6 can be separated quickly, and the inner seat 1, the outer seat 5 and the lens 7 can be quickly disassembled to prevent the lens 7 from cutting the face.
[0040] As a preferred embodiment, such as Figure 3 , 4 As shown, the lens 7 is provided with corresponding insertion holes, and the outer magnet 6 passes through the insertion holes and forms surface contact with the inner magnet 3, so that the two magnets have sufficient locking force, so that the outer seat 5 and the inner seat 1 can more reliably clamp the lens 7 from the inside and outside.
[0041] To achieve better limiting effect and better structural constraint, the following structural optimization scheme is proposed: the outer magnet 6 is a trapezoidal structure, and the inner magnet 3 is a rectangular or trapezoidal structure. The contact surface between the outer magnet 6 and the inner magnet 3 is a rectangular surface. The outer magnet 6 is movably inserted into the insertion hole of the lens 7. Through the positioning and cooperation of the two short sides of the outer magnet 6 with the insertion hole of the lens 7, the outer magnet 6 is limited to the cooperation position, which also limits the position of the inner magnet 3.
[0042] In addition, such as Figure 4As shown, the outer magnet 6 protrudes backward from the inner side of the lens 7, and can be movably inserted into the mounting groove of the inner seat 1 and attract the inner magnet 3, forming a better limiting effect.
[0043] As a preferred embodiment, such as Figure 2 , 3 As shown, the inner seat 1 is provided with two forward-protruding, breakable positioning protrusions 2 that can break in the event of a violent impact to the glasses. The two breakable positioning protrusions 2 are distributed vertically and are positioned and engaged with the side of the lens 7 and the outer seat 5.
[0044] As a preferred positioning solution, such as Figure 3 , 4 As shown, the outer seat 5 has two outer positioning grooves 5a that correspond one-to-one with the breakable positioning protrusion 2. The groove openings of the outer positioning grooves 5a are arranged facing rearward. The lens 7 has mirror side positioning grooves 7b that are the same number as the outer positioning grooves 5a and correspond one-to-one. The breakable positioning protrusion 2 can be detachably inserted into the corresponding mirror side positioning groove 7b and can be detachably inserted into the corresponding outer positioning groove 5a.
[0045] As one of the structural optimization schemes, the above-mentioned breakable positioning protrusion 2 is designed as an L-shape. One part of the breakable positioning protrusion 2 is separably inserted into the lens side positioning groove 7b, and the other part of the breakable positioning protrusion 2 is separably inserted into the outer positioning groove 5a and abuts against the outer side of the lens 7, thereby constraining / limiting the breakable positioning protrusion 2.
[0046] The breakable positioning protrusion 2 is a key technical feature in the magnetic connection structure, and has the following functions: The breakable positioning protrusion 2 is inserted into the outer positioning groove 5a and abuts against the lens side positioning groove 7b. The breakable positioning protrusion 2 hooks the lens 7 and abuts against the outer side of the lens 7. The inner seat 1 abuts against the inner side of the lens 7. The breakable positioning protrusion 2 mechanically locks the relative position of the lens 7 and the temple 4. When the user is subjected to a strong impact due to an accident, the breakable positioning protrusion 2 breaks under the impact force. The impact force drives the outer magnet 6 to separate from the inner magnet 3, which can instantly separate the inner seat 1 from the outer seat 5, preventing the lens 7 from scratching the user.
[0047] To ensure the inner and outer clamping functions of the inner seat 1 and the outer seat 5, such as Figure 1 As shown, the surface of the outer seat 5 that is in contact with the outer side of the lens 7 is a curved surface that matches the outer surface of the lens 7, and the surface of the inner seat 1 that is in contact with the inner side of the lens 7 is a curved surface that matches the inner surface of the lens 7. In short, both the inner seat 1 and the outer seat 5 form surface contact with the lens 7; the lens 7 is preferably a spherical mirror, and the clamping surfaces of the inner seat 1 and the outer seat 5 are also spherical, matching / matching the surface of the lens 7.
[0048] like Figure 3As shown, the outer seat 5 has two outer locking pins 5b integrally provided on the surface that fits against the outer side of the lens 7, and the inner seat 1 has two pin positioning holes 1a on the surface that fits against the inner side of the lens 7. The outer locking pins 5b pass through the lens positioning holes 7a of the lens 7 and are inserted into the pin positioning holes 1a one by one, thereby further ensuring the relative positional accuracy between the inner seat 1, the outer seat 5 and the lens 7.
[0049] like Figure 5 , 6 As shown, in a preferred type of temple 4, at least one portion of the temple 4 is detachably fitted with a contact pad 8 that contacts the head. The contact pad 8 is made of thermoplastic elastic material, and its contact surface has several inner contact protrusions 8a, forming multi-point contact, reducing pressure on the contact area, and combining wearing comfort with a secure fit. The contact pad 8 can be located at at least one point on the temple 4, providing a wraparound feel when worn and preventing it from falling off.
[0050] Because the contact pad 8 is detachable, a contact pad 8 of the appropriate size can be replaced to accommodate different head circumferences.
