Description

Technical Field

[0001] This utility model belongs to the field of smart glasses technology, specifically relating to a magnetic lens structure for smart glasses. Background Technology

[0002] To address the issue of smart glasses for people with myopia or hyperopia, most smart glasses products come with additional refractive corrective lenses, which are typically installed directly onto the glasses themselves.

[0003] A magnetic myopia glasses, such as the one described in announcement number CN221841282U, includes a smart glasses main body and a myopia support assembly connected to the smart glasses main body. The myopia support assembly includes a myopia lens and a lens frame that matches the shape of the myopia lens for fixing the lens. A lens body connecting part for connecting to the smart glasses main body is integrally formed in the middle of the lens frame. A body connecting part that matches the lens body connecting part is provided on the smart glasses main body. A first magnet is provided in the lens body connecting part, and a second magnet is provided in the body connecting part corresponding to the first magnet. The myopia support assembly is fixed to the smart glasses main body by the magnetic attraction of the first magnet and the second magnet. In practical applications, the magnetic attraction structure makes it easier and faster to assemble and disassemble the myopia support assembly.

[0004] However, currently, the nose pad component 12 of smart glasses in the industry is generally adjustable forward and backward, such as... Figures 1-2 As shown, by adjusting the nose pad assembly 12 forward and backward, the distance between the smart glasses body 11 and the human eye can be adjusted on the one hand, and the comfort problem of different people wearing them can also be solved on the other hand. Therefore, if the refractive lens is installed directly between the smart glasses body 11, the refractive lens will also move with the smart glasses body 11 when the nose pad assembly 12 is adjusted. The forward and backward movement of the refractive lens will directly change the lens-to-eye distance, thereby affecting the light focusing position and visual clarity, causing discomfort to the wearer.

[0005] In view of this, the present invention provides a magnetic lens structure for smart glasses to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smart glasses magnetic lens structure, including a glasses body and an adjustable nose pad assembly connected to the glasses body, wherein a refractive corrective lens assembly is detachably connected to the nose pad assembly so that the refractive corrective lens assembly can move synchronously with the adjustment of the nose pad assembly.

[0007] Preferably, the refractive lens assembly includes a connecting block and lenses connected to both sides of the connecting block. The connecting block has a second magnetic block embedded in its surface relative to the nose pad assembly, and the nose pad assembly has a first magnetic block embedded in its surface relative to the connecting block, which can magnetically attract and fix the second magnetic block.

[0008] Preferably, the nose pad assembly includes an elastic clip for forming an elastic engagement with the eyeglass body, a connecting rod connected to both sides of the elastic clip, and a pad leaf connected to the extended end of the connecting rod.

[0009] Preferably, the elastic card is U-shaped, with one end connected to a bent piece disposed relative to the connecting block, and the magnetic block is embedded in the surface of the bent piece.

[0010] Preferably, the connecting block is further provided with buckles on both sides relative to the connecting rod. When the magnetic block one and the magnetic block two are magnetically attracted, the connecting rod is clamped between the buckles and the side of the connecting block.

[0011] Preferably, the buckle includes a connecting portion connected at one end to the side of the connecting block, and an elastically bent portion connected at the other end of the connecting portion. A gap smaller than the width of the connecting rod is formed between the bent portion and the connecting block, so that the bent portion forms a clamping force on the outside of the connecting rod.

[0012] Preferably, the other end of the bent portion away from the connecting portion is further provided with a limiting portion for restricting the movement of the connecting rod within the gap.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention installs the refractive lens assembly directly between the nose pad assembly and the nose pad assembly, so that when the nose pad assembly is adjusted, the refractive lens assembly moves with the nose pad assembly and does not move with the main body of the smart glasses, thus not changing the interpupillary distance of the refractive lens and improving wearing comfort.

[0015] This utility model allows for easy assembly and disassembly of the refractive lens assembly and the nose pad assembly through the magnetic connection between magnetic block one and magnetic block two, so that they can be adjusted and used according to the actual wearer's situation.

[0016] This invention, through its snap-fit ​​design, makes the installation of the refractive lens assembly and the nose pad assembly more secure, preventing the refractive lens assembly from shifting due to external forces. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] This utility model relates to a magnetic lens structure for smart glasses, such as... Figures 1-6 As shown, the glasses include a main body 11, an adjustable nose pad assembly 12 connected to the main body 11, and a refractive lens assembly 2 detachably connected to the nose pad assembly 12, so that when the nose pad assembly 12 is adjusted, the refractive lens assembly 2 can move synchronously with the nose pad assembly 12 to maintain the lens-to-eye distance between the refractive lens assembly 2 and the human eye.

[0031] Among them, such as Figure 7 As shown, the nose pad assembly 12 includes an elastic clip 121 for forming an elastic engagement with the eyeglass body 11, a connecting rod 123 connected to both sides of the elastic clip 121, and a nose pad leaf 124 connected to the extended end of the connecting rod 123. The elastic clip 121 is generally U-shaped and has a spring (marked in the figure). One end of the elastic clip 121 can be inserted into a corresponding groove (marked in the figure) opened on the eyeglass body 11 for installation. Several arc-shaped protrusions (marked in the figure) are provided in the groove. When the elastic clip 121 is inserted, it is engaged in the gap between the arc-shaped protrusions by the spring, so as to realize the movable adjustment between the nose pad assembly 12 and the eyeglass body 11.

[0032] Furthermore, the other end of the elastic card 121 is connected to a bent piece 122 disposed relative to the connecting block 21, and a magnetic block 125 is embedded on the surface of the bent piece 122.

[0033] Among them, such as Figure 8 As shown, the refractive lens assembly 2 includes a square connecting block 21 and lenses 22 for refractive correction, such as myopia or hyperopia lenses, connected to both sides of the connecting block 21. A second magnetic block 23, capable of forming a magnetic connection with the first magnetic block 125, is embedded in the surface of the connecting block 21 relative to the curved plate 122. In this embodiment, the overall width of the connecting block 21 is the same as the minimum spacing between the connecting rods 123. In use, the surface of the connecting block 21 with the embedded magnetic block 23 is inserted between the connecting rods 123 of the nose pad assembly 12. The magnetic connection between the first magnetic block 125 and the second magnetic block 23 achieves magnetic fixation between the refractive lens assembly 2 and the nose pad assembly 12. Simultaneously, the magnetic connection also facilitates the disassembly of the refractive lens assembly 2 to meet the needs of different users.

[0034] Example 2:

[0035] Figures 4-6 , Figures 8-9The second embodiment of the present invention differs from the first embodiment in that: the connecting block 21 is further provided with buckles 24 on both sides relative to the connecting rod 123. When the magnetic block 125 and the magnetic block 23 are magnetically attracted, the connecting rod 123 is clamped between the buckles 24 and the side of the connecting block 21 to further fix the refractive correction lens assembly 2.

[0036] like Figure 9 As shown, the buckle 24 is generally L-shaped, including a connecting part 241 connected to the side of the connecting block 21 at one end, and a flexible bending part 242 connected to the other end of the connecting part 241. The bending part 242 can be made of elastic plastic or elastic metal. A gap smaller than the width of the connecting rod 123 is formed between the bending part 242 and the connecting block 21, so that the bending part 242 forms a clamping force on the outside of the connecting rod 123.

[0037] In use, when the connecting block 21 is inserted between the connecting rods 123 of the nose pad assembly 12, the connecting rods 123 can be inserted into the gap through the opening between the buckle 24 and the connecting block 21. Through the elastic deformation of the bending part 242, the bending part 242 provides an inward component force perpendicular to the insertion direction of the connecting block 21, so that the bending part 242 clamps the outside of the connecting rod 123, thereby further cooperating with the magnetic connection between the magnetic block one 125 and the magnetic block two 23, making the installation between the refractive lens assembly 2 and the nose pad assembly 12 more secure and less prone to displacement due to external forces or human activity. In addition to cooperating with the magnetic attraction between the magnetic block one 125 and the magnetic block two 23, the buckle 24 can also replace the magnetic connection between the magnetic block one 125 and the magnetic block two 23, so that the refractive lens assembly 2 can also be detachably connected to the nose pad assembly 12 directly through the design of the buckle 24.

[0038] Furthermore, a limiting part 243 for restricting the movement of the connecting rod 123 within the gap is also provided at the other end of the bent portion 242 away from the connecting portion 241. In this embodiment, the limiting part 243 is a semi-circular protrusion, integrally connected to the inner side of the bent portion 242. In use, since the bent portion 242 can continuously conform to the outer side of the connecting rod 123 to form a clamping action due to its own elasticity, the limiting part 243 provided on the inner side of the bent portion 242 can restrict the movement of the connecting rod 123 to a certain extent, that is, to form an obstacle on the movement path of the connecting rod 123 as it enters the gap, so as to effectively prevent the connecting rod 123 from coming out of the gap on its own.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
