Description

Technical Field

[0001] The present disclosure relates to the field of wearable technology, and in particular to a pair of glasses and a hinge assembly. Background Art

[0002] The clamping force of the temples of glasses is usually provided by elastic components. Due to the limited internal space size of the glasses, the compression space of the elastic components is small. If you want to obtain a larger clamping force in the end, you need to use elastic components with a larger elastic coefficient. As a result, during the outward expansion of the temples, there is a large gap between the initial clamping force and the final clamping force. That is, users with small head circumference will feel insufficient clamping force, while users with large head circumference will feel a very obvious clamping force. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Figure 1The glasses 100 provided by some embodiments of the present disclosure are shown, including a frame 3 and temples 2, wherein the frame 3 is used to support optical elements, and the temples 2 are connected to the frame 3. The temples 2 can move relative to the frame 3 to adjust the angle of the temples relative to the frame. When a user wears the glasses 100, the temples 2 apply a clamping force to the user's head so that the glasses 100 can be worn stably.

[0029] In some optional embodiments of the present disclosure, the clamping force applied by the temple 2 can be provided by the temple 2 itself. For example, the temple 2 includes a portion made of a flexible material, so that the temple 2 has a deformation capability. When the temple 2 is extended, the temple 2 is elastically deformed to apply a clamping force to the user's head.

[0030] In some optional embodiments of the present disclosure, the clamping force applied by the temple 2 can also be provided by an elastic component 13 disposed between the temple 2 and the frame 3. When the temple 2 is opened, the elastic component 13 is deformed. The deformation recovery force generated by the elastic component 13 causes the temple 2 to generate a clamping force.

[0031] Figure 2 A schematic diagram showing the temples of the glasses provided by the embodiment of the present disclosure are in a first position, Figure 3 A schematic diagram of the temple of the glasses provided by the embodiment of the present disclosure when in the second position is shown. In some embodiments of the present disclosure, the temple 2 has a first position and a second position relative to the frame 3, and the temple 2 can move between the first position and the second position relative to the frame, wherein when the temple 2 just leaves the first position, a first clamping force is provided at the clamping portion of the temple 2; when the temple 2 reaches the second position, a second clamping force is provided at the clamping portion; and the ratio of the second clamping force to the first clamping force is greater than 1 and less than or equal to 1.3.

[0032] In some embodiments of the present disclosure, the first position may be the position where the temple 2 is in a naturally opened state; the second position may be the position where the temple 2 is at a maximum opening angle relative to the frame 3.

[0033] In some embodiments of the present disclosure, the first position may be the position where the temple 2 provides the minimum clamping force, and the second position may be the position where the temple 2 provides the maximum clamping force.

[0034] When the first position is the position where the temple 2 is in a naturally open state, the clamping force applied by the temple 2 is zero, that is, the temple 2 does not apply a clamping force. When the temple 2 leaves the first position, the user wearing the glasses 100 can immediately feel the clamping force applied by the temple 2.

[0035] The clamping force applied to the user's head by the temples 2 of the glasses 100 provided in the embodiment of the present disclosure does not increase significantly during the outward extension process, and the clamping force felt by users with small head circumference and users with large head circumference when wearing the glasses 100 is not much different, so that users with different head circumferences can all have a good comfort experience when wearing the glasses 100 provided by the present disclosure.

[0036] In some embodiments of the present disclosure, when the temple 2 is in the first position, the frame and the temple 2 have a first angle; when the temple 2 is in the second position, the frame and the temple 2 have a second angle, and the difference between the first angle and the second angle is greater than or equal to 15 degrees and less than or equal to 25 degrees.

[0037] When the temple 2 is opened from 15 degrees to 25 degrees, the clamping force applied by the temple 2 to the user's head does not increase significantly, and the clamping force felt by the user does not change significantly, so that users with different head circumferences can have a comfortable wearing experience. In the disclosed embodiment, when the temple 2 is opened from 15 degrees to 25 degrees, the clamping space between the two temples 2 has a large variation range, which can meet the wearing needs of most users, so that most users can have a good wearing experience.

[0038] In some embodiments of the present disclosure, the first clamping force is greater than or equal to 0.23 kgf·cm and less than or equal to 0.27 kgf·cm, where kgf is kilogram force and cm is centimeter.

[0039] Generally, most of the weight of the glasses 100 is distributed on the frame 3. When the user wears the glasses 100, the bridge of the user's nose bears most of the weight of the glasses 100, and the ears bear a small part of the weight of the glasses 100. The first clamping force greater than or equal to 0.23kgf·cm and less than or equal to 0.27kgf·cm is applied by the temple 2 at the clamping part, which can effectively reduce the pressure of the glasses 100 on the bridge of the user's nose, conform to the ergonomic design, and prevent the glasses 100 from sliding down or falling off, and the user has a good wearing experience.

[0040] In some embodiments of the present disclosure, the distance between the clamping part and the connection between the temple 2 and the frame is 7.5 cm to 8.5 cm. The clamping part is the part on the temple 2 that contacts the user's head, and the clamping part directly applies a clamping force to both sides of the user's head. A large number of experiments have shown that after most users wear the glasses 100, the distance between the part on the temple 2 that contacts the user's head and the frame 3 is 7.5 cm to 8.5 cm. This part is the clamping part, and the clamping force applied by the clamping part can enable most users to enjoy a comfortable wearing experience.

[0041] Optionally, when the temple 2 is fixed to the frame 3 by a fastener, the clamping portion is a portion on the temple 2 that is 7.5 cm to 8.5 cm away from the connection with the frame; when the temple 2 is hinged to the frame 3, the clamping portion is a portion on the temple 2 that is 7.5 cm to 8.5 cm away from the rotation center of the temple 2.

[0042] In some embodiments of the present disclosure, when the temple 2 is in the first position, the angle between the temple 2 and the frame 3 is greater than or equal to 83 degrees and less than or equal to 87 degrees. The first position may be a position where the temple 2 is in a naturally opened state or a position close to the naturally opened state. When the temple 2 is in the first position, the temple 2 does not exert a clamping force; when the temple 2 opens outward and leaves the first position, the user will immediately feel the clamping force.

[0043] In some embodiments of the present disclosure, the weight of the glasses 100 is greater than or equal to 50 grams and less than or equal to 100 grams. By limiting the weight of the glasses 100 to between 50 grams and 100 grams, the pressure of the glasses on the user's head (such as the bridge of the nose and ears) can be reduced, the discomfort symptoms that may occur after long-term wearing can be alleviated, and the wearing comfort can be improved.

[0044] In some embodiments of the present disclosure, when the weight of the glasses 100 is greater than or equal to 50 grams and less than or equal to 100 grams, a first clamping force greater than or equal to 0.23 kgf·cm and less than or equal to 0.27 kgf·cm is applied at the clamping portion by the temple 2. This can effectively reduce the pressure of the glasses 100 of this weight on the user's nose bridge, conform to ergonomic design, and prevent the glasses 100 from slipping or falling off, providing a good wearing experience for the user.

[0045] Figure 4 FIG. 2 shows an exploded view of a partial structure of glasses using the first hinge assembly provided by an embodiment of the present disclosure. Figure 4 As shown, the glasses 100 provided in some embodiments of the present disclosure include: a frame 3, temples 2 and an elastic component 13. The elastic component 13 is arranged between the frame 3 and the temples 2. The elastic component 13 prevents the temples 2 from rotating from the first position to the second position.

[0046] The elastic component 13 is used to provide a damping force for the temples 2 to expand outward relative to the frame 3. When the glasses 100 are worn on the user's head, the two temples 2 of the glasses 100 expand outward. The damping force provided by the elastic component 13 can enable the two temples 2 to clamp the user's head, so that the temples 2 can share the pressure of the nose pads of the glasses 100, and enable the glasses 100 to be stably worn on the user's head. In the process of the temples 2 opening relative to the frame 3, the elastic deformation of the elastic component 13 will increase, and the elastic component 13 will apply a damping force to the temples 2, so that the temples 2 apply a clamping force to the user's head in the opposite direction to the damping force. The elastic component 13 includes, but is not limited to, a torsion spring, a spring, a tension spring, a compression spring and a damping shaft.

[0047] Figure 5 FIG. 1 is a schematic diagram showing the structure of a hinge assembly of glasses using a torsion spring provided in some embodiments of the present disclosure. Figure 5 As shown, when the elastic component 13 of the glasses 100 adopts a torsion spring, in the first position, the torsion spring is limited between the temple 2 and the frame 3 at a preset torsion angle; in the process of the temple 2 opening to the second position, the torsion angle of the torsion spring increases, and the torsion spring will provide a damping force to the temple 2 to hinder its rotation, so that the temple 2 applies a clamping force to the user's head in the opposite direction of the damping force.

[0048] In some embodiments of the present disclosure, the elastic component 13 of the glasses 100 may also be a spring. Optionally, the spring has two straight pieces, and in a natural state, the two straight pieces are at a certain angle. In the first position, the spring is limited between the temple 2 and the frame 3 at a preset angle; when the temple 2 is opened, the angle between the two straight pieces changes, thereby providing a damping force to the temple 2 to hinder its rotation, so that the temple 2 applies a clamping force to the user's head in the opposite direction to the damping force.

[0049] In some embodiments of the present disclosure, the elastic component 13 of the glasses 100 may be a tension spring. In the first position, the tension spring is limited between the temple 2 and the frame 3 with a preset stretched length; when the temple 2 is opened to the second position, the stretched length of the tension spring continues to increase, thereby providing a damping force to the temple 2 to hinder its rotation, so that the temple 2 applies a clamping force to the user's head in the opposite direction to the damping force.

[0050] In some embodiments of the present disclosure, the elastic component 13 of the glasses 100 may be a compression spring. In the first position, the compression spring is limited between the temple 2 and the frame 3 with a preset compression length; when the temple 2 is opened to the second position, the compression length of the tension spring continues to decrease, thereby providing a damping force to the temple 2 to hinder its rotation, so that the temple 2 applies a clamping force on the user's head in the opposite direction to the damping force.

[0051] In some embodiments of the present disclosure, the elastic component 13 of the glasses 100 may be a damping shaft. When the temple leaves the first position, the damping shaft immediately provides a damping force; when the temple 2 is opened to the second position, the damping shaft may provide an increased damping force, thereby providing a damping force to the temple 2 to hinder its rotation, so that the temple 2 applies a clamping force on the user's head in the opposite direction to the damping force. Optionally, the damping shaft may also provide a constant damping force, or a variable damping force.

[0052] In some embodiments of the present disclosure, the glasses 100 also include a hinge assembly 1, which is disposed between the temple 2 and the frame, the temple 2 is rotatably connected to the frame via the hinge assembly 1, the temple 2 and the frame 3 are connected via the hinge assembly 1, the hinge assembly 1 can realize relative rotation between the frame 3 and the temple 2 to adjust the angle of the temple 2 relative to the frame 3, and the elastic component 13 is disposed on the hinge assembly 1.

[0053] The following provides a hinge assembly that can be used for the glasses provided in the embodiments of the present disclosure.

[0054] Figure 5 It is shown that some embodiments of the present disclosure provide a first hinge assembly 1. Figure 5 As shown, the hinge assembly 1 may include: a first component 11 and a second component 12, the first component 11 and the second component 12 are rotatably connected, and the two can rotate relative to each other within a certain angle range. The first component 11 can be used to connect the temple 2, and the second component 12 is used to connect the frame 3, so as to achieve the connection between the temple 2 and the frame 3. When the first component 11 and the second component 12 rotate relative to each other, the temple 2 and the frame 3 rotate relative to each other, and the angle between the temple 2 and the frame 3 can be adjusted.

[0055] Combination Figure 4 and Figure 5 As shown, the first component 11 includes a first extension portion 111 and a second extension portion 114, and the first extension portion 111 and the second extension portion 114 are connected. Optionally, the first extension portion 111 and the second extension portion 114 may extend in different directions, that is, there may be an angle between the first extension portion 111 and the second extension portion 114. Alternatively, the first extension portion 111 and the second extension portion 114 may extend along a curve, for example, the first extension portion 111 and the second extension portion 114 extend along an arc. Figure 2As shown, the second component 12 includes a limiting portion 121 that is relatively arranged. The limiting portion 121 that is relatively arranged can accommodate the second extension portion 114 and can provide space for the second extension portion 114 to move. Optionally, there are two limiting portions 121, and the two limiting portions 121 are spaced apart and relatively arranged. The first component 11 and the second component 12 are rotatably connected, and the second extension portion 114 of the first component 11 is located between the limiting portions 121 that are relatively arranged, and the second extension portion 114 can rotate around the first axial direction, so that the temple 2 can rotate around the first axial direction relative to the frame 3. The limiting portion 121 of the second component 12 limits the extreme position of the relative rotation of the second extension portion 114, that is, it limits the range of relative rotation of the second extension portion 114. Thereby, the relative rotation range of the temple 2 and the frame 3 can be limited.

[0056] In some embodiments of the present disclosure, Figure 5 As shown, an elastic component 13 is disposed inside the hinge assembly 1. The elastic force of the elastic component 13 can be used as a reset force for the first component 11 to move relative to the second component 12, that is, a damping force for the temple 2 to open outward relative to the frame 3.

[0057] like Figure 5 As shown, the elastic component 13 is located between the first component 11 and the second component 12, and is used to provide a restoring force for the first extension portion 111 to rotate closer to the second component 12. Under the action of external force, when the temple 2 is opened relative to the frame 3, the elastic component 13 located between the first component 11 and the second component 12 is deformed by the force. After the external force is removed, the elastic component 13 recovers the deformation, so that the temple 2 is retracted inwardly relative to the frame 3. The setting of the elastic component 13 provides a damping force for the temple 2 to expand outward relative to the frame 3, so that the temple 2 can share the pressure of the nose pad of the glasses 100, and the glasses 100 worn on the human body are not easy to fall off, thereby improving the wearing comfort.

[0058] In some embodiments of the present disclosure, the second component 12 may include two limiting portions 121 disposed on the inner side and the outer side. Optionally, when the temple 2 is extended, the second extension portion 114 may be used to compress the elastic component 13 so that the elastic component 13 provides a reverse restoring force, which may be achieved by arranging the elastic component 13 between the second extension portion 114 and the inner limiting portion 121. Alternatively, when the temple 2 is extended, the second extension portion 114 may be used to stretch the elastic component 13 so that the elastic component 13 provides a reverse restoring force, which may be achieved by arranging the elastic component 13 between the second extension portion 114 and the outer limiting portion 121. In some embodiments of the present disclosure, the elastic component 13 is located between the second extension portion 114 and any limiting portion 121 of the second component 12, so that when the first extension portion 111 rotates away from the second component 12, the second extension portion 114 acts on the elastic component 13 to deform the elastic component 13. For example, the second extension portion 114 can compress or stretch the elastic component 13 to deform the elastic component 13 or increase the deformation of the elastic component 13. Thus, the elastic component 13 provides a restoring force for the first extension portion 111 to rotate toward the second component 12.

[0059] It is understandable that the "inner limit portion 121" mentioned above can be understood as the limit portion 121 close to the face when the glasses 100 are worn. The "outer limit portion 121" can be understood as the limit portion 121 away from the face when the glasses 100 are worn.

[0060] In some embodiments of the present disclosure, the second component 12 includes two connecting arms 122 , and the two connecting arms 122 and the limiting portion 121 form an accommodating space, and the second extending portion 114 is accommodated in the accommodating space.

[0061] In an optional embodiment, each connecting arm 122 is respectively connected to two limiting portions 121. Optionally, the plane where the connecting arm 122 is located is substantially perpendicular to the limiting portion 121. The two connecting arms 122 can be used to limit the position of the second extension portion 114, and the distance between the two connecting arms 122 is slightly larger than the width of the second extension portion 114, so that the second extension portion 114 can be limited to swing only within the accommodation space in cooperation with the two limiting portions 121.

[0062] In some embodiments of the present disclosure, the first component 11 further includes a first rotating connection portion 113, which is connected to at least one of the two connecting arms 122. The connecting arm 122 also provides a physical structure for installing the first rotating connection portion 113, which facilitates the connection between the second component 12 and the first component 11.

[0063] In some optional embodiments, combined with Figure 4As shown, the first rotating connection portion 113 may include a connecting shaft 1132, and the connecting shaft 1132 is used to connect the first component 11 and the second component 12, so that the temple 2 can rotate relative to the frame 3 around the connecting shaft, and the axial direction of the connecting shaft 1132 is the first axial direction. Optionally, the connecting shaft 1132 and the first component 11 can be detachable separate parts; or, the connecting shaft 1132 and the first component 11 can also be integrally formed.

[0064] In some optional embodiments, such as Figure 5 and Figure 6 As shown, the first rotating connection part 113 may include a connecting column 1131, which is arranged at the corner between the first extension part 111 and the second extension part 114, and the connecting column 1131 has a column hole 1131a. The connecting shaft 1132 may be fixedly or rotatably connected to the column hole 1131a. The first connecting hole 1221 may be arranged on the connecting arm 122 of the second component 12, and the connecting shaft 1132 is plugged into the column hole 1131a and the first connecting hole 1221. In this way, the second component 12 can be rotatably connected to the connecting shaft.

[0065] Optionally, the connecting shaft 1132 may include a column and a cap body disposed at one end of the column, and the end of the column away from the cap body passes through the first connecting hole 1221 on the upper connecting arm 122 and the column hole 1131a of the connecting column 1131 in sequence, and then is connected to the first connecting hole 1221 on the lower connecting arm 122. Among them, at least one of the first connecting hole 1221 and the column hole 1131a may be provided with an internal thread, and the connecting shaft 1132 may be provided with an external thread, and the column is at least threadedly connected with one of the first connecting hole 1221 and the column hole 1131a. The cap body is limited to the connecting arm 122 on the upper side. The connecting column 1131 is arranged at the angle between the first extension portion 111 and the second extension portion 114, and occupies less space of the first extension portion 111 and the second extension portion 114, does not affect the connection between the first extension portion 111 and the temple 2, and does not affect the cooperation between the second extension portion 114 and the second component 12.

[0066] In some embodiments of the present disclosure, the first component 11 may include a mounting plate connected to the first extension portion 111 and the second extension portion 114, and the mounting plate extends from the first extension portion 111 to the second extension portion 114. The connecting column 1131 may be provided on the mounting plate. The column hole 1131a passes through the connecting column 1131 and the mounting plate at the same time, so that the connecting axis of the first rotating connecting portion 113 passes through the connecting column 1131 and the mounting plate. Optionally, the plane where the mounting plate is located is substantially perpendicular to at least one of the plane where the first extension portion 111 is located and the plane where the second extension portion 114 is located, and the mounting plate is connected to the ends of the first extension portion 111 and the second extension portion 114 on the same side.

[0067] In some embodiments of the present disclosure, the elastic component 13 located between the first component 11 and the second component 12 may include a bent spring sheet, and the bent portion of the spring sheet is sleeved on the connecting column 1131. Exemplarily, the bent spring sheet may be roughly U-shaped, with an outer convex arc sheet and two straight sheets located on both sides of the outer convex arc sheet. The connecting column 1131 may be located in the inner groove of the outer convex arc sheet, and the two straight sheets are respectively pressed against the limiting portion 121 and the second extension portion 114.

[0068] In some embodiments of the present disclosure, the elastic component 13 located between the first component 11 and the second component 12 may include a torsion spring. Figure 4 , Figure 5 and Figure 6 The structure schematic diagram of the hinge assembly 1 or glasses using a torsion spring provided in some embodiments of the present disclosure is shown. The elastic component 13 may include a torsion spring, which is sleeved on the connecting column 1131. The torsion spring has a spiral barrel section and torsion arms located at both ends of the spiral barrel section. The spiral barrel section is sleeved on the connecting column 1131, and the two torsion arms are located in the accommodating space and respectively abut against the second extension portion 114 and the limiting portion 121.

[0069] In the model of the first hinge assembly 1, the force arm of the temple 2 and the force arm of the elastic component 13 have an angle. Figure 7 The force diagram of the first hinge assembly 1 using a torsion spring is shown. The clamping force provided by the temple 2 is F', and the force arm of the clamping force F' is L'; the elastic force of the torsion spring, that is, the damping force F provided by the torsion spring to prevent the second component from rotating relative to the first component, and the force arm of the damping force F is L.

[0070] It is understandable that in some cases, the damping force provided by the torsion spring may not be perpendicular to the lever arm, and the damping force can be divided into: a damping force perpendicular to the lever arm, and a damping force along the lever arm direction. Among them, the damping force F perpendicular to the lever arm is an effective damping force that can prevent the second component from rotating relative to the first component. The damping forces mentioned in the present disclosure that prevent the second component from rotating relative to the first component are all effective damping forces.

[0071] Figure 8 It is shown that some embodiments of the present disclosure provide a structure of a second hinge assembly 1 . Fig. 9A force diagram of the second hinge assembly provided by an embodiment of the present disclosure is shown. The second hinge assembly 1 includes a first component 11 and a second component 12, wherein the first component 11 is connected to the temple 2, and the second component 12 is connected to the frame 3. The first component 11 can be regarded as a part of the temple 2; the second component 12 can be regarded as a part of the frame 3. Optionally, the second component 12 can be arranged at the end of the frame 3; or, the second component 12 can also be a pile head arranged at the end of the frame 3. The first component 11 and the second component 12 are hingedly connected, and compression spring positioning columns are arranged on the first component 11 and the second component 12. The elastic component 13 can be a compression spring, and the two ends of the compression spring are respectively mounted on the compression spring positioning columns on the first component 11 and the second component 12. The clamping force provided by the temple 2 is F', and the force arm of the clamping force F' is d'; the elastic force of the compression spring, that is, the damping force F provided by the compression spring to hinder the rotation of the second component relative to the first component, and the force arm of the damping force F is d. As Fig. 9 As shown, the arm d of the elastic component 13 is located on the extension line of the arm d' of the temple 2; the arm d of the elastic component 13 is located on the frame. The arm d' of the temple 2 and the arm d of the frame 3 are located on both sides of the rotation center of the temple 2 respectively.

[0072] Fig.10 FIG. 1 shows a partial structural schematic diagram of glasses using a third hinge assembly provided by an embodiment of the present disclosure. Fig.11 A partial cross-sectional view of glasses using a third hinge assembly provided by an embodiment of the present disclosure is shown. Fig.12 The third hinge assembly provided by the embodiment of the present disclosure is shown in the structural schematic diagram. In a possible implementation, the frame 3 has a frame shell and a first connection seat 33 connected to the frame shell. The temple 2 has a temple shell and a second connection seat 22 connected to the temple shell. The first connection seat 33 and the second connection seat 22 are connected by a hinge.

[0073] The frame 3 and each temple 2 are connected by two hinges. Two second connection seats 22 are arranged on the temple 2 along the width direction, two first connection seats 33 are arranged at the end of the frame 3, and a hinge assembly 1 is connected between each first connection seat 33 and each second connection seat 22. The hinge assembly 1 includes a first rod 14, a second rod 15 and an elastic component, which may be a tension spring 17. The second rod 15 is connected to the first rod 14, and a rotating shaft hole 141 is arranged on the first rod 14. The second rod 15 is sleeved with a sliding ring 16 and a tension spring 17. A blocking piece is provided at one end of the second rod 15 away from the first rod 14. The tension spring 17 is located between the sliding ring 16 and the blocking piece. A limiting groove 161 is provided on the sliding ring 16. The second connecting seat 22 has a through hole 23 and a threaded hole 24 connected to the through hole 23. The hinge second rod 15 is inserted into the through hole 23. The limiting screw 18 passes through the threaded hole 24 on the second connecting seat 22 and abuts against the limiting groove 161 of the sliding ring 16 to limit the position of the sliding ring 16. The first connecting seat 33 can be fixed to the main body of the frame 3 by a rotating shaft seat screw 35. The rotating shaft screw 34 passes through the first connecting seat 33 and penetrates the rotating shaft hole 141 on the first rod 14, so as to realize the assembly of the hinge assembly. During the process of folding or opening the temple 2, the relative positions of the temple 2 and the ends of the frame 3 will change, and the sliding sleeve can slide on the second rod body 15 to satisfy the above-mentioned position change relationship. The setting of the tension spring 17 on the hinge ensures that the relative position of the temple 2 and the frame 3 is relatively stable when the temple 2 is opened or folded. When the temple 2 is opened, the tension spring 17 on the hinge assembly 1 produces elastic deformation and is applied to the temple 2, so that the temple 2 produces a clamping force.

[0074] The clamping force provided by the temple 2 is F', and the force arm of the clamping force F' is d'; the elastic force of the tension spring 17 is the damping force F provided by the tension spring to prevent the second component from rotating relative to the first component, and the force arm of the damping force F is d. Fig. 9 As shown, the arm d of the elastic component 13 of the third hinge assembly 1 is collinear with the arm d' of the temple 2, and the arm d of the elastic component 13 is located on the temple 2. The arm of the temple 2 and the arm of the elastic component 13 are located on the same side of the rotation center and on the same straight line.

[0075] It should be noted that the force arms of the elastic components 13 mentioned above are all equivalent force arms.

[0076] The following is an exemplary parameter table corresponding to the torsion spring solution adopted by the elastic component 13 in some embodiments of the present disclosure.

[0077] First Position Second Position Temple 2 angle <![CDATA[φ1=85°(±2°)]]> <![CDATA[φ2=105°(±2°)]]> Temple 2 clamping force <![CDATA[F1’=0.25(±0.02)kgf]]> <![CDATA[F2’=0.3(±0.02)kgf]]> Torque <![CDATA[T1=2.0(±0.2)kgf·cm]]> <![CDATA[T2=2.5(±0.2)kgf·cm]]> Torsion angle of torsion spring <![CDATA[θ1=66.7°~92.6°]]> <![CDATA[θ2=θ1+20°]]> Torsion spring torque <![CDATA[F1=T1 / L]]> <![CDATA[F2=T2 / L]]>

[0078] In some embodiments of the present disclosure, at the clamping position of the temple 2 at a distance of 8 cm (±0.5) from the rotation axis, the clamping force (F') is set to vary in the range of 0.25 (±0.02) kgf (corresponding to the temple 85°) to 0.3 (±0.02) kgf (corresponding to the temple 105°), the corresponding torque range is 1.72 kgf.cm to 2.72 kgf·cm, and the torsion spring torque T range is selected to be 2.0 (±0.2) kgf·cm to 2.5 (±0.2) kgf·cm;

[0079] The relevant calculation formula for torsion spring is as follows:

[0080] Stretch:

[0081] Torque: T (kgf cm) = F * L;

[0082] Where: k-elastic coefficient,

[0083] Torsion arm length, according to the structural space, the optional torsion arm length L is 0.5cm to 0.7cm, for example, 0.6cm can be selected. The value range of k is 0.036kgf / degree to 0.05kgf / degree. θ-torsion angle, according to the formula F=T1 / L=k*θ, F1=2.0 / 0.6=k*θ1, the torsion angle θ1 in the first position ranges from 66.7° to 92.6°. When the elastic component 13 adopts a torsion spring, when the temple 2 is in the first position, the torsion spring has a first torsion angle compared to the natural state, and the value range of the first torsion angle is 66.7° to 92.6°. As a result, when the temple 2 leaves the first position, the damping force of the torsion spring can be immediately converted into the clamping force of the clamping part of the temple 2, so that users with smaller head circumference can also feel sufficient clamping force, thereby reducing the pressure of the glasses on the user's nose bridge.

[0084] In some optional embodiments of the present disclosure, Figure 5 As shown, the two torsion arms of the torsion spring respectively abut against the second extension portion 114 and the limiting portion 121. When the second extension portion 114 abuts against the outer limiting portion 121 (i.e., when the temple is in the first position), the torsion spring has a first torsion angle in the range of 66.7° to 92.6°.

[0085] When the temple 2 is in the first position, the elastic component 13 applies a first damping force to the temple 2 to hinder its rotation. When the temple 2 reaches the second position, the elastic component 13 applies a second damping force to the temple 2 to restore it to the first position. The elastic component 13 includes a torsion spring, and the ratio of the first clamping force to the first damping force is greater than 10 and less than or equal to 17.

[0086] In some optional embodiments of the present disclosure, Figure 5As shown, when the temple 2 is in the first position, the second extension portion 114 abuts against the outer limiting portion 121, and the temple 2 is in a natural state at this time, and the clamping force provided is zero; when the temple 2 leaves the first position due to an external force, the second extension portion 114 leaves the outer limiting portion 121, and the torsion spring immediately applies a first damping force to the temple 2 to hinder its rotation, so that the temple 2 provides a first clamping force at its clamping position; when the temple 2 reaches the second position, the second extension portion 114 abuts against the inner limiting portion 121, and the torsion spring applies a second damping force to the temple 2 to reset it to the first position, and the ratio of the first clamping force to the first damping force is greater than 10 and less than or equal to 17.

[0087] When the elastic component 13 is a torsion spring, when the temple 2 is in the first position, the frame and the temple 2 have a first angle; when the temple 2 is in the second position, the frame and the temple 2 have a second angle; the elastic coefficient of the torsion spring is the ratio of the difference between the second damping force and the first damping force to the difference between the second angle and the first angle, and the value of the elastic coefficient is greater than or equal to 0.036kgf / degree and less than or equal to 0.05kgf / degree.

[0088] When the elastic component 13 is a torsion spring, the wire diameter of the torsion spring is greater than or equal to 0.8 and less than or equal to 1.0 mm. In the embodiment of the present disclosure, the wire diameter of the torsion spring can be selected as 0.85 mm. The effective number of turns of the torsion spring is greater than or equal to 2 turns and less than or equal to 4 turns. In the embodiment of the present disclosure, the effective number of turns can be selected as 3 turns. The middle diameter of the torsion spring is greater than or equal to 2 mm. Due to the limitations of the torsion spring forming process, the inner diameter of the torsion spring with a wire diameter of more than 0.85 mm should be greater than 2 mm. The inner diameter of the torsion spring with a wire diameter of 2.5 mm or more should be selected in the embodiment of the present disclosure, that is, the middle diameter is 3.35 mm. The material of the torsion spring is stainless steel, and the rigidity modulus can be 19400.

[0089] Fig.14 The figure shows the relationship curve between the clamping force and the outward angle of the temple provided by the embodiment of the elastic component 13 of the present disclosure using the torsion spring and the embodiment of the prior art obtained by simulation, wherein the vertical axis represents the clamping force of the temple and the horizontal axis represents the angle between the temple and the frame. Fig.14 As shown, when the angle between the temple and the frame is 85°, the temple is in a natural state (i.e., the first position, at which the clamping force is zero), and when the angle between the temple and the frame is 105°, the temple has a maximum rotation angle relative to the frame (i.e., the second position, at which the clamping force is maximum). Among them, the elastic component 13 of the prior art embodiment uses three compression springs, whose wire diameter is 0.5mm, length is 7mm, and outer diameter is 2mm. It can be seen from the above curve that the difference between the initial clamping force and the final clamping force of the embodiment of the present disclosure is small, while the difference between the initial clamping force and the final clamping force of the existing ordinary hinge is large.

[0090] By selecting a suitable torsion spring, the damping force of the torsion spring can be converted into the clamping force of the temples within a limited space, reducing the pressure of the temples on the bridge of the nose, and ensuring that the clamping force of the two temples does not increase significantly within a sufficient clamping space, so that users with different head circumferences can have a comfortable experience.

[0091] The elastic coefficient of the torsion spring can be calculated according to the following torsion spring parameter formula:

[0092] The k value obtained is 0.046kgf / degree, which meets the above requirements.

[0093] Among them, θ-torsion angle, according to the formula F=T / L=k*θ, F1=2.0 / 0.6=0.046*θ, the first torsion angle is 73° (i.e., θ1=73°), corresponding to the angle between the temple 2 and the horizontal being 85°. After the torsion spring is stretched 20°, the second torsion angle is 93° (i.e., θ2=93°), corresponding to the angle between the temple 2 and the horizontal being 105°, F2=k*θ2=4.28kgf, T2=F2*L=4.28*0.6=2.57kgf·cm, which meets 2.5(±0.2)kgf·cm, F1'=T1 / d'=2.0 / 8=0.25kgf, F2'=T2 / d'=2.57 / 8=0.32kgf, which meets the clamping force standard of 0.25(±0.02)kgf to 0.3(±0.02)kgf.

[0094] See also Figure 5 As shown, some embodiments of the present disclosure provide a structural schematic diagram of a hinge assembly 1. The hinge assembly 1 is used for hingedly connecting the frame and the temple 2 of the glasses 100, and the hinge assembly 1 includes: a first component 11, a second component 12 and an elastic component 13. The first component 11 is connected to the frame, or the first component 11 is a part of the frame. The second component 12 is connected to the temple 2, or the second component 12 is a part of the temple 2. The first component 11 and the second component 12 are rotatably connected, and the second component 12 has a first position and a second position relative to the first component 11, and the second component 12 can rotate relative to the first component 11 between the first position and the second position. The elastic component 13 is arranged between the first component 11 and the second component 12, and is used to provide a first torque to keep the second component 12 in the first position, and a second torque to rotate the second structural member from the second position to the first position; wherein the ratio of the second torque to the first torque is greater than 1 and less than or equal to 1.3.

[0095] In some embodiments of the present disclosure, the first position may be a position where the second component 12 is in a naturally opened state. The second position may be a position where the second component 12 is at a maximum opening angle.

[0096] In some embodiments of the present disclosure, the first position may be a position where the elastic component 13 provides a minimum rotational torque, and the second position may be a position where the elastic component 13 provides a maximum rotational torque.

[0097] In some embodiments of the present disclosure, when the second component 12 is located at the first position, the first component 11 and the second component 12 have a first angle; when the second component 12 is located at the second position, the first component 11 and the second component 12 have a second angle; the first angle and the second angle differ by 15° to 25°.

[0098] When the second part 12 is opened from 15 to 25 degrees, the clamping force applied by the temples 2 on the user's head does not increase significantly, and the clamping force felt by the user does not change significantly, so that users with different head circumferences can have a comfortable wearing experience. In the disclosed embodiment, when the second part 12 is opened from 15 to 25 degrees, the clamping space between the two temples 2 has a large variation range, which can meet the wearing needs of most users, so that most users can have a good wearing experience.

[0099] In some embodiments of the present disclosure, the first moment is greater than or equal to 1.7 kgf·cm and less than or equal to 2.3 gf·cm. Thus, the pressure of the glasses on the user's nose bridge can be effectively reduced, which conforms to the ergonomic design and prevents the glasses from sliding down or falling off, providing a good wearing experience for the user.

[0100] In some embodiments of the present disclosure, the elastic component 13 includes a torsion spring, and when the second component 2 is in the first position, the torsion spring has a first torsion angle compared to the natural state, and the first torsion angle is greater than or equal to 66.7 degrees and less than or equal to 92.6 degrees. Thus, when the second component 2 just leaves the first position, the damping force of the torsion spring can be immediately converted into the clamping force of the clamping part of the temple 2, so that users with smaller head circumferences can also feel sufficient clamping force, thereby reducing the pressure of the glasses on the user's nose bridge.

[0101] In some embodiments of the present disclosure, the elastic component 13 includes a torsion spring; the elastic coefficient of the torsion spring is the ratio of the difference between the second damping force and the first damping force to the difference between the second angle and the first angle, and the value of the elastic coefficient is greater than or equal to 0.036kgf / degree and less than or equal to 0.05kgf / degree.

[0102] In some embodiments of the present disclosure, the elastic component 13 is a torsion spring, the wire diameter of the torsion spring is greater than or equal to 0.8 and less than or equal to 1.0 mm, the effective number of turns is greater than or equal to 2 turns and less than or equal to 4 turns, the middle diameter is greater than or equal to 2 mm, and the material of the torsion spring is stainless steel.

[0103] By selecting a suitable torsion spring, the damping force of the torsion spring can be converted into the clamping force of the temples within a limited space, reducing the pressure of the temples on the bridge of the nose, and ensuring that the clamping force of the two temples does not increase significantly within a sufficient clamping space, so that users with different head circumferences can have a comfortable experience.
