TECHNICAL FIELD
[0001] The present application relates to the technical field of eyewear accessories, in particular to an ear hook and eyewear. BACKGROUND
[0002] Eyewear can include corrective eyewear and smart eyewear, and smart eyewear is widely promoted and developed due to its rich functions. Smart eyewear can include a frame, a temple, a lens, and smart system components.
[0003] In order to prevent the eyewear from sliding down or falling off during wearing, an ear hook can be installed on the temple to prevent the temple from sliding off the ear, thereby improving the wearing stability of the eyewear.
[0004] However, the ear hook in the above related technology has poor anti-sliding and anti-falling effects on the eyewear, affecting the practicality of the ear hook. INNOVATION CONTENT
[0005] The present application provides an ear hook and eyewear, which can improve the fitting effect of the ear hook and the outer contour of the ear, improve the anti-sliding and anti-falling effects of the ear hook, and further improve the practicality of the ear hook.
[0006] The first aspect of the present application provides an ear hook, which comprises: an ear hook structure comprising a first edge portion and a second edge portion oppositely arranged along a first direction, the first edge portion being closer to the outer contour of the ear relative to the second edge portion.
[0007] An adjusting structure is arranged in the ear hook structure, and the adjusting structure is used to adjust the shape of the first edge portion through plastic deformation, so that the first edge portion fits the outer contour of the ear.
[0008] The present application provides an ear hook, which adjusts the shape of the outer contour of the ear hook structure through the adjusting structure arranged in the ear hook structure, so that at least the first edge portion of the ear hook structure can fit the outer contour of the ear. Thus, the contact area between the ear hook structure and the outer contour of the ear can be increased, the frictional resistance between the ear hook structure and the outer contour of the ear can be improved, the difficulty of sliding of the ear hook relative to the outer contour of the ear can be reduced, the anti-sliding and anti-falling effects of the ear hook on the eyewear can be improved, and the practicality and application range of the ear hook can be improved.
[0009] In addition, by adjusting the shape of the outer contour of the ear hook structure through the adjusting structure, at least the first edge portion can fit the outer contour of the ear, the stress area between the ear hook structure and the outer contour of the ear can be increased, the problem of excessive local pressure on the ear caused by excessive concentration of stress points on the outer contour of the ear can be avoided, and the wearing comfort of the ear hook can be improved.
[0010] On the basis of the above, the present application also makes the following improvements:
[0011] In a possible implementation, the ear hook structure extends along a second direction;
[0012] and the adjusting structure extends along the second direction, and the adjusting structure is arranged close to the first edge portion;
[0013] The second direction intersects the first direction.
[0014] In this way, when the adjusting structure is plastically deformed, the adjusting distance of the adjusting structure along the length direction of the ear hook structure can be increased, the ear hook structure can better fit the outer contour of the ear, the fitting area of the ear hook structure and the outer contour of the ear can be increased, and the frictional resistance can be increased, effectively preventing the glasses from sliding down or falling off.
[0015] By arranging the adjusting structure on the ear hook structure close to the first edge portion, the adjusting structure can more directly adjust the contact surface of the ear hook structure and the outer contour of the ear. The user can flexibly adjust the angle and curved shape of the first edge portion of the ear hook structure relative to the temple, so that the ear hook structure can more closely fit the outer contour of the ear.
[0016] In a possible implementation, the ear hook structure extends along a second direction;
[0017] The adjusting structure extends along the second direction, and the adjusting structure is arranged close to the second edge portion;
[0018] The second direction intersects the first direction.
[0019] In this way, by arranging the adjusting structure on the ear hook structure close to the second edge portion, the hardness of the first edge portion of the ear hook structure can be avoided to be too large when the adjusting structure is arranged close to the first edge portion, thereby affecting the wearing comfort of the ear hook.
[0020] In a possible implementation, the adjusting structure is arranged along the circumference of the contour of the ear hook structure.
[0021] In this way, by arranging the adjusting structure along the circumference of the contour of the ear hook structure, the adjusting range of the adjusting structure to the ear hook structure can be improved, the adjusting effect on the outer contour of the ear hook structure can be improved, and the fitting effect of the ear hook structure and the outer contour of the ear can be improved.
[0022] In a possible implementation, the ear hook structure includes a first end and a second end opposite to each other along the second direction;
[0023] The first end is used to be connected with the temple of the glasses;
[0024] The ear-hanging structure gradually decreases in size in the first direction from the first end to the second end.
[0025] In this way, by gradually decreasing the size of the ear-hanging structure in the first direction from the first end to the second end, the pressure applied to the outer contour of the ear can be reduced, and the wearing comfort of the ear hook can be improved, compared to the case where the size of the ear-hanging structure in the first direction does not change, while ensuring the stability of the connection between the ear-hanging structure and the temple at the first end.
[0026] In a possible implementation, the ear-hanging structure further comprises a weak part;
[0027] The weak part is located between the first edge part and the second edge part, and the weak part is arranged close to the first end.
[0028] In this way, by arranging the weak part close to the first end on the ear-hanging structure, the strength of the corresponding ear-hanging structure at the weak part is reduced relative to the case where the weak part is not arranged, so that the structural strength of the ear-hanging structure close to the first end can be reduced, so as to adjust the shape of the first edge part corresponding to the first end on the ear-hanging structure, for example, the shape of the area corresponding to the first end of the first edge part, so that the part of the first edge part close to the first end can better fit the outer contour of the ear, thereby improving the fitting effect of the entire ear-hanging structure with the outer contour of the ear.
[0029] In a possible implementation, in the thickness direction of the ear-hanging structure, the thickness of the weak part is less than the thickness of other positions on the ear-hanging structure.
[0030] In this way, by making the thickness of the weak part less than the thickness of other positions on the ear-hanging structure in the thickness direction of the ear-hanging structure, the structural strength of the weak part can be lower than the strength of other positions on the ear-hanging structure, so as to facilitate adjusting the shape of the first edge part corresponding to the weak part, so that the first edge part can better fit the outer contour of the ear.
[0031] In a possible implementation, the weak part is a through hole.
[0032] In the thickness direction of the ear-hanging structure, the through hole penetrates the ear-hanging structure.
[0033] In this way, by arranging the weak part as a through hole, the structural strength of the weak part can be lower than the strength of other positions on the ear-hanging structure, while also achieving heat dissipation at the weak part, so that the heat on the side of the ear-hanging structure that fits the skin of the user can be dissipated through the through hole, thereby improving the wearing comfort of the ear hook.
[0034] In one possible implementation, the ear hook further includes a mounting portion disposed at the first end, the mounting portion being used to connect to the temple of the eyeglasses.
[0035] In this way, by setting an installation part at the first end of the ear hook, it is easier to connect the ear hook structure to the temple of the glasses, improve the connection stability between the ear hook and the temple, and reduce the chance of the ear hook falling off the temple.
[0036] In one possible implementation, the stiffness of the adjustment structure is greater than the stiffness of the ear loop structure.
[0037] In this way, by making the stiffness of the adjustment structure greater than that of the ear hook structure, it is possible to adjust the shape of the ear hook structure while maintaining the deformed state of the ear hook structure.
[0038] In one possible implementation, the adjustment structure is a plastically deformable metal wire.
[0039] In this way, by setting the adjustment structure as a malleable metal wire, the metal wire has a large structural strength, which makes it easy to adjust the shape of the ear hook structure by adjusting the shape of the metal wire, so that at least the first side of the ear hook structure fits the outer contour of the ear.
[0040] In one possible implementation, the cross-sectional shape of the metal wire is circular, and the diameter of the circular metal wire is greater than or equal to 0.6 mm and less than or equal to 1.2 mm.
[0041] By ensuring the cross-sectional diameter of the circular metal wire is greater than or equal to 0.6 mm, the problem of low structural strength due to an excessively small wire diameter can be avoided, preventing the ear hook structure from being difficult to adjust due to low structural strength, and also preventing the wire from breaking easily due to a small diameter. Conversely, by ensuring the cross-sectional diameter of the circular metal wire is less than 1.2 mm, the problem of excessively high structural strength due to a large cross-sectional diameter can be avoided, preventing the wire from being difficult to bend and deform due to excessive structural strength. Therefore, by setting the cross-sectional diameter of the circular metal wire within the range of greater than or equal to 0.6 mm and less than or equal to 1.2 mm, the wire is guaranteed to be resistant to breakage and the shape of the ear hook structure can be adjusted, while avoiding the problem of an excessively large wire diameter that would hinder the user's ability to adjust the ear hook structure by bending the wire.
[0042] In one possible implementation, the metal wire is a titanium wire, a stainless steel wire, or a copper wire.
[0043] In this way, by setting the metal wire as a titanium metal wire, since the density of titanium metal is low, the weight of the metal wire can be reduced, facilitating the lightweight setting of the ear hook. Titanium metal has good corrosion resistance, so the probability of damage of the metal wire due to corrosion during use can be reduced, the service life of the metal wire is improved, and the service life of the ear hook can be improved.
[0044] By setting the metal wire as a stainless steel wire, the material cost of stainless steel is relatively low, so the manufacturing cost of the adjusting structure can be reduced on the basis of ensuring the shape of the ear hanging structure adjusted by the metal wire, and the manufacturing cost of the ear hook can be reduced.
[0045] In a possible implementation, the adjusting structure is embedded in the ear hanging structure.
[0046] In this way, by embedding the adjusting structure in the ear hanging structure, the adjusting structure can be prevented from directly contacting the skin of the user, and the comfort of the user when wearing the ear hook can be affected due to the direct contact between the adjusting structure and the user, thereby improving the practicality and wearing comfort of the ear hook.
[0047] In a possible implementation, the ear hanging structure can be a silica gel piece or a rubber piece.
[0048] In this way, by setting the ear hanging structure as a silica gel piece, since the silica gel piece is soft and elastic, the wearing comfort of the ear hook can be improved, facilitating the user to wear the ear hook for a long time. In addition, the silica gel piece has good skin-friendliness, which can prevent damage to the skin when worn for a long time, and improve the use safety of the ear hook. In addition, the silica gel piece has good anti-aging performance, which can improve the service life of the ear hook.
[0049] By setting the ear hanging structure as a rubber piece, for example, setting the ear hanging structure as thermoplastic polyurethane (TPU). TPU has good wear resistance and tear resistance, which can effectively resist wear and tear in daily use, and also has good anti-bending damage performance, which helps to prolong the service life of the ear hanging structure. In addition, TPU has good oil resistance, water resistance, and chemical corrosion resistance, which can prevent the ear hanging structure from being corroded by corrosive liquids such as human sweat during long-term use, further improving the service life of the ear hook.
[0050] And / or, the hardness of the ear hanging structure is greater than or equal to 30A and less than or equal to 60A.
[0051] In this way, by making the hardness of the ear hook structure greater than 30A, it can be avoided that the ear hook structure has too small structural strength due to too small hardness of the ear hook structure, so that it can be avoided that the ear hook structure cannot provide sufficient support to the glasses due to too small structural strength of the ear hook structure. By making the hardness of the ear hook structure less than 60A, it can be avoided that the ear hook structure has too large structural strength due to too large hardness of the ear hook structure, so that it can be avoided that the adjustment structure cannot adjust the shape of the ear hook structure due to too large strength of the ear hook structure. Therefore, by controlling the hardness of the ear hook structure in the range of greater than or equal to 30A and less than or equal to 60A, it can be ensured that the ear hook structure provides sufficient support to the glasses, and it is also convenient to adjust the shape of the ear hook structure by the adjustment structure.
[0052] A second aspect of the embodiment of the present application provides a pair of glasses, which comprises a frame, a temple, and an ear hook as described above.
[0053] The ear hook is connected to the temple.
[0054] The pair of glasses provided by the embodiment of the present application can improve the wearing stability of the glasses by arranging the ear hook on the temple, and the ear hook contacts the outer contour of the ear, and the ear hook can reduce the probability of sliding and falling of the temple by increasing the friction resistance between the ear hook and the outer contour of the ear.
[0055] The ear hook can have an ear hook structure and an adjustment structure, and the adjustment structure can adjust the outer contour of the ear hook structure, so that the ear hook structure better fits the outer contour of the ear, so as to increase the contact area between the ear hook and the outer contour of the ear, and further increase the friction resistance between the ear hook and the outer contour of the ear, reduce the difficulty of sliding of the ear hook relative to the outer contour of the ear, further reduce the probability of sliding and falling of the temple from the ear, and improve the wearing stability of the glasses.

[0067] The ear hook can be used for glasses to reduce the probability of glasses sliding down or falling off when being worn. The glasses can be glasses that have a frame and a temple and can be externally worn. For example, the glasses can be corrective glasses or smart glasses. The smart glasses can be audio smart glasses, shooting smart glasses, augmented reality glasses (AR glasses), virtual reality glasses (VR glasses), artificial intelligence glasses (AI glasses), etc.
[0068] Reference Figure 1 , Figure 1 A structural schematic diagram of glasses provided in the related art is shown.
[0069] The glasses can include a temple, a frame, a lens, and an ear hook. The ear hook is connected to the temple and can be used to hook the outer contour of the ear to prevent the glasses from falling off. However, the ear hook in the prior art has poor effects on preventing the glasses from sliding down and falling off, which affects the practicability of the ear hook.
[0070] The reason for this problem is that the ear hook generally relies on the outer contour of the ear. When the ear hook contacts the outer contour of the ear, frictional resistance is generated. The greater the frictional resistance, the less likely the glasses are to slide down or fall off, and the better the effects of the ear hook on preventing the glasses from sliding down and falling off. The contact area between the ear hook and the outer contour of the ear affects the size of the frictional resistance. The greater the contact area, the greater the frictional resistance. However, the outer contour shape of the ear hook in the prior art is relatively fixed. The outer contour shapes of different users' ears are different, which makes the ear hook unable to match and adapt to the outer contours of different ears, thereby affecting the fitting effect of the ear hook and the outer contour of the ear, further affecting the frictional resistance between the ear hook and the outer contour of the ear, affecting the effects of the ear hook on preventing the glasses from sliding down and falling off, and affecting the practicability of the ear hook.
[0071] In addition, if the glasses are smart glasses, the weight of the smart glasses is relatively large, which is more likely to cause the glasses as a whole to slide down or fall off.
[0072] In view of the above technical problems, the ear hook and the glasses are provided, the adjusting structure is arranged on the ear hanging structure, the adjusting structure can adjust the outer contour shape of the ear hanging structure through plastic deformation, so that the first edge portion of the ear hanging structure can be fitted to the outer contour of the ear, thereby increasing the contact area between the ear hanging structure and the outer contour of the ear, reducing the difficulty of sliding of the ear hook relative to the outer contour of the ear, improving the frictional resistance between the ear hanging structure and the outer contour of the ear, and further improving the anti-sliding and anti-falling effects of the ear hook on the glasses, and improving the practicability and application range of the ear hook.
[0073] In addition, by adjusting the shape of the outer contour of the ear hanging structure through the adjusting structure, the first edge portion is fitted to the outer contour of the ear, the stress area between the ear hanging structure and the outer contour of the ear is increased, the problem of excessive local pressure on the ear caused by excessive concentration of stress points on the outer contour of the ear is avoided, and the wearing comfort of the ear hook is improved.
[0074] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0075] Reference Figure 1 and Figure 2 The embodiments of the present application provide a pair of glasses 1, which can include a frame 12, a temple 11 and an ear hook 2. The temple 11 can include two temples 11, which are respectively arranged at two ends of the frame 12. The ear hook 2 can include two ear hooks 2, and each temple 11 can be provided with one ear hook 2. The glasses 1 can further include a lens 13, which is arranged on the frame 12.
[0076] The glasses 1 provided by the embodiments of the present application can increase the frictional resistance between the ear hook 2 and the outer contour of the ear 3 by arranging the ear hook 2 on the temple 11 and contacting the outer contour of the ear 3, thereby reducing the probability of sliding and falling of the temple 11 and improving the wearing stability of the glasses 1.
[0077] The ear hook 2 can have an ear hanging structure 100 and an adjusting structure 200. The adjusting structure 200 can adjust the outer contour of the ear hanging structure 100, so that the ear hanging structure 100 better fits the outer contour of the ear 3, thereby increasing the contact area between the ear hook 2 and the outer contour of the ear 3, and further increasing the frictional resistance between the ear hook 2 and the outer contour of the ear 3, reducing the difficulty of the ear hook 2 sliding relative to the outer contour of the ear 3, further reducing the probability of the temple leg 11 sliding or falling off the ear 3, and improving the wearing stability of the glasses 1.
[0078] Reference Figure 2 The ear hook 2 can have an ear hanging structure 100 and an adjusting structure 200. The ear hanging structure 100 can include a first edge portion 110 and a second edge portion 120 arranged opposite along a first direction (such as the X direction). The first edge portion 110 is closer to the outer contour of the ear 3 relative to the second edge portion 120. The first edge portion 110 of the ear hanging structure 100 is used to contact the outer contour of the ear 3. The outer contour of the ear 3 can be the area behind the ear. Figure 2
[0079] The adjusting structure 200 is arranged on the ear hanging structure 100. The adjusting structure 200 is used to adjust the shape of the first edge portion 110 through plastic deformation, so that the first edge portion 110 fits the outer contour of the ear 3.
[0080] The ear hook 2 can have an ear hanging structure 100 and an adjusting structure 200. The adjusting structure 200 is arranged on the ear hanging structure 100. The adjusting structure 200 is used to adjust the shape of the first edge portion 110 through plastic deformation, so that the first edge portion 110 fits the outer contour of the ear 3.
[0081] Further, by adjusting the shape of the outer contour of the ear hanging structure 100 through the adjusting structure 200, at least the first edge portion 110 fits the outer contour of the ear 3, which can also increase the stress area of the ear hanging structure 100 and the outer contour of the ear 3, avoiding the problem of excessive local pressure on the ear 3 due to the excessive concentration of stress points on the outer contour of the ear 3, and improving the wearing comfort of the ear hook 2.
[0082] In some embodiments, the adjustment structure 200 can be a plastically deformable structural component, allowing the adjustment structure 200 to deform the ear hook structure 100 by changing its shape or curvature, thereby ensuring that the first side 110 of the ear hook structure 100 conforms as closely as possible to the outer contour of the ear 3. The adjustment structure 200 can be used to adjust the shape of the outer contour of the ear hook structure 100. For example, the adjustment structure 200 can adjust the curvature of the first side 110 on the ear hook structure 100 to better conform to the outer contour of the ear 3. Alternatively, the adjustment structure 200 can also adjust the overall shape of the outer contour of the ear hook structure 100, ensuring that the first side 110 conforms to the outer contour of the ear 3.
[0083] In some embodiments, the stiffness of the adjustment structure 200 may be greater than the stiffness of the ear hook structure 100.
[0084] In this way, by making the stiffness of the adjustment structure 200 greater than that of the ear hook structure 100, the ear hook structure 100 can be kept in its deformed state while the adjustment structure 200 can easily adjust the shape of the ear hook structure 100.
[0085] refer to Figure 2 In some embodiments, the ear loop structure 100 is along a second direction (e.g., Figure 2 The second direction can extend along the Y-direction, and can intersect the first direction, for example, the second direction can be perpendicular to the first direction. The adjustment structure 200 can extend along the second direction (e.g., the Y-direction). Figure 2 Extending in the Y direction.
[0086] In this way, when the adjustment structure 200 undergoes plastic deformation, it can increase the adjustment distance of the adjustment structure 200 on the ear hook structure 100 in the length direction, so that the ear hook structure 100 can better fit the outer contour of the ear 3, increase the contact area between the ear hook structure 100 and the outer contour of the ear 3, and increase the frictional resistance, effectively preventing the glasses 1 from slipping down or falling off.
[0087] refer to Figure 2 In some embodiments, the adjustment structure 200 can be positioned close to the first side 110.
[0088] In this way, by positioning the adjustment structure 200 on the ear hook structure 100 near the first side 110, the adjustment structure 200 can more directly adjust the contact surface between the ear hook structure 100 and the outer contour of the ear 3. Users can flexibly adjust the angle and curvature of the first side 110 of the ear hook structure 100 relative to the temple 11 according to the shape of their own ear 3, so that it fits the outer contour of the ear 3 more closely.
[0089] refer to Figure 3In some embodiments, the adjusting structure 200 is capable of being arranged close to the second edge 120, while ensuring that the adjusting structure 200 is capable of changing the shape of the ear-hanging structure 100 and capable of making the first edge 110 fit the outer contour of the ear 3.
[0090] In this way, by arranging the adjusting structure 200 on the ear-hanging structure 100 close to the second edge 120, the adjusting structure 200 arranged close to the first edge 110 can be avoided, which can cause the hardness of the first edge 110 of the ear-hanging structure 100 to be too large and affect the wearing comfort of the earhook 2.
[0091] In other embodiments, the adjusting structure 200 is also capable of being arranged on the first edge 110 and the second edge 120 of the ear-hanging structure 100 at the same time, so as to improve the adjusting and fixing ability of the adjusting structure 200 to the ear-hanging structure 100 and avoid the ear-hanging structure 100 from affecting the fitting effect of the ear-hanging structure 100 to the outer contour of the ear 3 due to the occurrence of recovery deformation after the adjustment of the adjusting structure 200.
[0092] In a possible implementation manner, the adjusting structure 200 is capable of being arranged along the circumference of the contour of the ear-hanging structure 100. In this way, by arranging the adjusting structure 200 along the circumference of the contour of the ear-hanging structure 100, the adjusting range of the adjusting structure 200 to the ear-hanging structure 100 can be improved, the adjusting effect to the outer contour of the ear-hanging structure 100 can be improved, and the fitting effect of the ear-hanging structure 100 to the outer contour of the ear 3 can be improved.
[0093] Reference Figure 2 and Figure 3 In some embodiments, the ear-hanging structure 100 can include a first end 130 and a second end 140 opposite to each other in the second direction. The first end 130 is used to be connected with the temple 11 of the glasses 1. In the direction from the first end 130 to the second end 140, the size of the ear-hanging structure 100 in the first direction (such as the length L) gradually decreases. Figure 2
[0094] In this way, in the direction from the first end 130 to the second end 140, by gradually reducing the size of the ear-hanging structure 100 in the first direction, the pressure applied to the outer contour of the ear 3 can be reduced and the wearing comfort of the earhook 2 can be improved, compared with the case where the size of the ear-hanging structure 100 in the first direction does not change, while ensuring the stability of the connection between the first end 130 of the ear-hanging structure 100 and the temple 11.
[0095] Reference Figure 2 and Figure 3 In some embodiments, if the size of the ear-hanging structure 100 in the first direction (such as the length L) gradually decreases in the direction from the first end 130 to the second end 140, the pressure applied to the outer contour of the ear 3 can be reduced and the wearing comfort of the earhook 2 can be improved. Figure 2 In some embodiments, the ear-hanging structure 100 gradually decreases in thickness from the first end 130 to the second end 140. In some embodiments, the ear-hanging structure 100 gradually decreases in thickness from the first end 130 to the second end 140, and the ear-hanging structure 100 gradually decreases in thickness from the first end 130 to the second end 140 in the first direction. In some embodiments, the ear-hanging structure 100 gradually decreases in thickness from the first end 130 to the second end 140 in the first direction, and the ear-hanging structure 100 gradually decreases in thickness from the first end 130 to the second end 140 in the second direction.
[0096] In some embodiments, the ear-hanging structure 100 further comprises a weakened portion 150, the weakened portion 150 is located between the first edge portion 110 and the second edge portion 120, and the weakened portion 150 is located close to the first end 130.
[0097] In some embodiments, the ear-hanging structure 100 further comprises a weakened portion 150, the weakened portion 150 is located between the first edge portion 110 and the second edge portion 120, and the weakened portion 150 is located close to the first end 130.
[0098] In some embodiments, the ear-hanging structure 100 gradually decreases in thickness from the first end 130 to the second end 140 in the thickness direction of the ear-hanging structure 100. Figure 2 and Figure 3 In some embodiments, the thickness of the weakened portion 150 is less than the thickness of the ear-hanging structure 100 at other positions of the ear-hanging structure 100 in the thickness direction of the ear-hanging structure 100.
[0099] In some embodiments, the thickness of the weakened portion 150 is less than the thickness of the ear-hanging structure 100 at other positions of the ear-hanging structure 100 in the thickness direction of the ear-hanging structure 100.
[0100] In some embodiments, the first weakened portion 150 is a groove, and the thickness of the ear-hanging structure 100 at the groove is less than the thickness of the ear-hanging structure 100 at other positions of the ear-hanging structure 100.
[0101] In some embodiments, the first weakened portion 150 is a groove, and the thickness of the ear-hanging structure 100 at the groove is less than the thickness of the ear-hanging structure 100 at other positions of the ear-hanging structure 100. Figure 2 and Figure 3 In some embodiments, the weakened portion 150 is a through hole 151, and the through hole 151 penetrates the ear-hanging structure 100 in the thickness direction of the ear-hanging structure 100.
[0102] In this way, by setting the weak portion 150 as the through hole 151, the heat on the side of the ear hook structure 100 that is attached to the user's skin can be dissipated through the through hole 151, and the wearing comfort of the ear hook 2 is improved, on the premise that the structural strength of the weak portion 150 is lower than the strength of other positions on the ear hook structure 100.
[0103] Reference Figure 2 And Figure 3 In some embodiments, the ear hook 2 can further include a mounting portion 300, the mounting portion 300 being arranged on the first end 130, and the mounting portion 300 being used to connect with the temple 11 of the glasses 1.
[0104] In this way, by arranging the mounting portion 300 on the first end 130 of the ear hook 2, the connection between the ear hook structure 100 and the temple 11 of the glasses 1 is facilitated, the connection stability between the ear hook 2 and the temple 11 is improved, and the probability of the ear hook 2 falling off the temple 11 is reduced.
[0105] In some examples, the mounting portion 300 can be a sleeve connector, the sleeve connector having a mounting hole, and the temple 11 is arranged in the mounting hole to realize that the ear hook structure 100 is sleeved on the temple 11 through the mounting portion 300.
[0106] In this way, by setting the mounting portion 300 as a sleeve connector with a mounting hole, the structure of the mounting portion 300 is simplified, the manufacturing efficiency of the mounting portion 300 is improved, and the manufacturing cost of the mounting portion 300 is reduced, thereby the manufacturing efficiency of the ear hook 2 is improved, and the manufacturing cost of the ear hook 2 is reduced.
[0107] In some embodiments, the adjustment structure 200 can be a plastically deformable metal piece, such as a metal wire or a metal sheet. The metal piece has high durability, and the service life of the adjustment structure 200 is improved.
[0108] Reference Figure 2 And Figure 3 In some embodiments, the adjustment structure 200 can be a plastically deformable metal wire.
[0109] In this way, by setting the adjustment structure 200 as a plastically deformable metal wire, the structural strength of the metal wire is large, and the shape of the ear hook structure 100 is adjusted by adjusting the shape of the metal wire, so that at least the first side portion 110 of the ear hook structure 100 is attached to the outer contour of the ear 3.
[0110] Reference Figure 2 And Figure 3 In some embodiments, the cross-sectional shape of the metal wire is circular, for example, the metal wire can be a cylindrical metal wire.
[0111] In this way, by setting the cross section of the metal wire to be circular, the outer surface of the metal wire can be set to be a smooth curved surface, avoiding the metal wire from piercing the ear hanging structure 100 when embedded in the ear hanging structure 100 due to the edges of the outer surface. Alternatively, avoiding the edges of the outer surface of the metal wire from locally pressing against the skin of the user, affecting the comfort of the user when wearing.
[0112] In some embodiments, the cross section diameter of the circular metal wire is greater than or equal to 0.6mm and less than or equal to 1.2mm. For example, the cross section diameter of the circular metal wire can be one of 0.7mm, 0.8mm, 0.9mm, 1.0mm and 1.1mm. Alternatively, the cross section diameter of the circular metal wire can be any value within the range of greater than or equal to 0.6mm and less than or equal to 1.2mm.
[0113] In this way, by setting the cross section diameter of the circular metal wire to be greater than or equal to 0.6mm, the problem of the metal wire having a low structural strength due to the small diameter of the metal wire can be avoided, and the problem of the metal wire being unable to adjust the shape of the ear hanging structure 100 due to the low structural strength of the metal wire can be avoided, and the problem of the metal wire being easily broken due to the small diameter of the metal wire can be avoided. By setting the cross section diameter of the circular metal wire to be less than 1.2mm, the problem of the metal wire having a high structural strength due to the large cross section diameter of the metal wire can be avoided, and the problem of the metal wire not being easily deformed by bending due to the high structural strength of the metal wire can be avoided. Therefore, by setting the cross section diameter of the circular metal wire to be within the range of greater than or equal to 0.6mm and less than or equal to 1.2mm, the metal wire can be prevented from being too large in diameter to be adjusted by bending the metal wire to adjust the shape of the ear hanging structure 100, while ensuring that the metal wire is not easily broken and ensuring that the shape of the ear hanging structure 100 can be adjusted.
[0114] Reference Figure 2 and Figure 3 In some embodiments, the metal wire is a titanium metal wire, a stainless steel wire or a copper wire.
[0115] In this way, by setting the metal wire to be a titanium metal wire, the weight of the metal wire can be reduced due to the low density of titanium metal, facilitating the lightweight setting of the ear hook 2. Titanium metal has good corrosion resistance, so the probability of the metal wire being damaged due to corrosion during use can be reduced, the service life of the metal wire can be improved, and the service life of the ear hook 2 can be improved.
[0116] By setting the metal wire to be a stainless steel wire, the material cost of stainless steel is relatively low, so the manufacturing cost of the adjustment structure 200 can be reduced while ensuring that the shape of the ear hanging structure 100 can be adjusted by the metal wire, and the manufacturing cost of the ear hook 2 can be reduced.
[0117] Reference Figure 2 and Figure 3In some embodiments, the adjusting structure 200 is embedded in the ear hook structure 100.
[0118] In this way, by embedding the adjusting structure 200 in the ear hook structure 100, the adjusting structure 200 can be prevented from directly contacting the skin of the user, and the comfort of the user when wearing the ear hook 2 can be affected by the direct contact between the adjusting structure 200 and the user, thereby improving the practicability and wearing comfort of the ear hook 2.
[0119] In some embodiments, if the adjusting structure 200 is a metal wire, the metal wire can be embedded in the ear hook structure 100 to prevent the metal wire from scratching the skin of the user during the wearing of the ear hook 2, thereby improving the safety of the ear hook 2.
[0120] In some embodiments, if the adjusting structure 200 is embedded in the ear hook structure 100 and the adjusting structure 200 is a metal wire, at least one end of the metal wire in the extending direction is wrapped with a protective piece, for example, one end of the metal wire in the length direction is provided with a protective piece, or both ends of the metal wire in the length direction are provided with protective pieces.
[0121] In this way, by providing a protective piece at least at one end of the metal wire in the length direction, the metal wire can be prevented from damaging the ear hook structure 100, for example, by providing a protective piece to prevent the metal wire from piercing the ear hook structure 100, thereby improving the safety and service life of the ear hook structure 100.
[0122] Reference Figure 2 and Figure 3 In some embodiments, the ear hook structure 100 can be a silicone piece or a rubber piece.
[0123] In this way, by providing the ear hook structure 100 as a silicone piece, since the silicone piece is relatively soft and elastic, the wearing comfort of the ear hook 2 can be improved, and the user can wear the ear hook 2 for a long time. In addition, the silicone piece has good skin-friendliness, which can prevent damage to the skin when the user wears it for a long time, thereby improving the safety of the ear hook 2. In addition, the silicone piece has good anti-aging performance, which can improve the service life of the ear hook 2.
[0124] By setting the ear hook structure 100 as a rubber piece, for example, setting the ear hook structure 100 as a thermoplastic polyurethane (TPU) rubber. The TPU has good wear resistance and tear resistance, which can effectively resist wear and tear in daily use, and also has good bending damage resistance, which helps to prolong the service life of the ear hook structure 100. In addition, the TPU has good oil resistance, water resistance, and chemical corrosion resistance, which can avoid the ear hook structure 100 being corroded by corrosive liquids such as human sweat during long-term use, further improving the service life of the ear hook 2.
[0125] In some embodiments, the hardness of the ear hook structure 100 can be greater than or equal to 30A and less than or equal to 60A. For example, the hardness of the ear hook structure 100 can be one of 35A, 40A, 45A, 50A, and 55A. Alternatively, the hardness of the ear hook structure 100 can be any value within the range of greater than or equal to 30A and less than or equal to 60A.
[0126] In this way, by making the hardness of the ear hook structure 100 greater than 30A, the structural strength of the ear hook structure 100 can be avoided due to the hardness of the ear hook structure 100 being too small, so that the ear hook structure 100 cannot provide sufficient support to the glasses 1 due to the structural strength of the ear hook structure 100 being too small. By making the hardness of the ear hook structure 100 less than 60A, the structural strength of the ear hook structure 100 can be avoided due to the hardness of the ear hook structure 100 being too large, so that the adjustment structure 200 cannot adjust the shape of the ear hook structure 100 due to the strength of the ear hook structure 100 being too large. Therefore, by controlling the hardness of the ear hook structure 100 within the range of greater than or equal to 30A and less than or equal to 60A, the ear hook structure 100 can provide sufficient support to the glasses 1, and the shape of the ear hook structure 100 can be adjusted by the adjustment structure 200.
