Description

Technical Field

[0001] The present disclosure relates to the field of wearable technologies, and more particularly to a pair of glasses and a hinge assembly. Background Art

[0002] The clamping force of the temple of a pair of glasses is usually provided by an elastic member. Due to the limited internal space size of the glasses, the compression space of the elastic member is small. If a relatively large clamping force is to be finally obtained, an elastic member with a relatively large elastic coefficient needs to be selected. Therefore, during the outward movement of the temple, the difference between the initial clamping force and the final clamping force is large. That is, users with a small head circumference will feel insufficient clamping force, while users with a large head circumference will feel a very obvious clamping force. Summary of the Invention

[0003] Embodiments of the present disclosure provide a pair of glasses and a hinge assembly.

[0004] On the one hand, the present disclosure provides a pair of glasses, including: a frame and temples. The frame is used to support optical elements, and the temples are connected to the frame. Wherein, the temples have a first position and a second position relative to the frame, and the temples can rotate relative to the frame between the first position and the second position. When the temples leave the first position, a first clamping force is provided at the clamping portion of the temples; when the temples reach the second position, a second clamping force is provided at the clamping portion; the ratio of the second clamping force to the first clamping force is greater than 1 and less than or equal to 1.3.

[0005] On the other hand, the present disclosure further provides a hinge assembly for hingedly connecting the frame and the temples of a pair of glasses. The hinge assembly includes a temple, a frame, and an elastic member. The first member is connected to the frame or the first member is a part of the frame. The frame is connected to the temple or the frame is a part of the temple. The temple and the frame are rotatably connected. The frame has a first position and a second position relative to the temple. The second member can rotate relative to the first member between the first position and the second position. The elastic member is disposed between the temple and the frame and is used to provide a first moment for keeping the frame in the first position and a second moment for rotating the second structural member from the second position towards the first position; wherein, the ratio of the second moment to the first moment is greater than 1 and less than or equal to 1.3.

Detailed implementation manners

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0026] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] In the description of the present invention, it should be noted that unless otherwise clearly defined 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 directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

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

[0029] In some alternative 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, such that the temple 2 has the ability to deform. When the temple 2 is splayed outwards, the temple 2 undergoes elastic deformation to apply a clamping force to the user's head.

[0030] In some alternative embodiments of the present disclosure, the clamping force applied by the temple 2 can also be provided by the elastic member 13 disposed between the temple 2 and the spectacle frame 3. During the process of the temple 2 opening, the elastic member 13 deforms. The deformation restoring force generated by the elastic member 13 causes the temple 2 to generate a clamping force.

[0031] Figure 2 A schematic diagram showing the spectacle temple provided by the embodiment of the present disclosure in the first position is shown. Figure 3 A schematic diagram showing the spectacle temple provided by the embodiment of the present disclosure 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 spectacle frame 3, and the temple 2 is capable of moving between the first position and the second position relative to the spectacle frame. Among them, 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; 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 natural open state; the second position may be the position where the temple 2 is at the maximum opening angle relative to the spectacle 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 natural 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] During the process of the temple 2 of the glasses 100 provided by the embodiment of the present disclosure splaying outwards, the clamping force applied to the user's head does not increase significantly, and the difference in the clamping force felt by the user with a small head circumference and the user with a large head circumference when wearing the glasses 100 is not large, so that users with different head circumferences have a good comfortable 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, there is a first included angle between the frame and the temple 2; when the temple 2 is in the second position, there is a second included angle between the frame and the temple 2, and the difference between the first included angle and the second included angle is greater than or equal to 15 degrees and less than or equal to 25 degrees.

[0037] During the process of the temple 2 moving from being opened by 15 degrees to being opened by 25 degrees, the clamping force exerted by the temple 2 on the user's head does not increase significantly, and the clamping force felt by the user does not change significantly either, so that users with different head circumferences can all have a comfortable wearing experience. In the embodiments of the present disclosure, when the temple 2 is opened by 15 degrees to 25 degrees, the clamping space between the two temples 2 has a large change 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. Here, 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 user's nose bridge bears most of the weight of the glasses 100, and the two ears bear a small part of the weight of the glasses 100. By applying a first clamping force greater than or equal to 0.23 kgf·cm and less than or equal to 0.27 kgf·cm at the clamping part by the temple 2, the pressure of the glasses 100 on the user's nose bridge can be effectively reduced, which conforms to the ergonomic design and at the same time prevents the glasses 100 from slipping 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 of the temple 2 and the frame is 7.5 cm to 8.5 cm. The clamping part is the part of 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. It is proved in a large number of experiments that for most users after wearing the glasses 100, the distance between the part of the temple 2 that contacts the user's head and the frame 3 is 7.5 cm to 8.5 cm, and this part is the clamping part. The clamping force applied through this clamping part can enable most users to enjoy a comfortable wearing experience.

[0041] Optionally, when the temple 2 is fixed to the frame 3 through a fastener, the clamping part is the part of the temple 2 with a distance of 7.5 cm to 8.5 cm from the connection with the frame; when the temple 2 is hinged to the frame 3, the clamping part is the part of the temple 2 with a distance of 7.5 cm to 8.5 cm 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 can be the position where the temple 2 is in the natural open state or a position close to the natural open state. When the temple 2 is in the first position, the temple 2 does not exert a clamping force; when the temple 2 is opened 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 be between 50 grams and 100 grams, the pressure of the glasses on the user's head (such as the bridge of the nose and both ears) can be reduced, the discomfort symptoms that may occur during long-term wearing can be alleviated, and the wearing comfort is 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, by applying a first clamping force greater than or equal to 0.23 kgf·cm and less than or equal to 0.27 kgf·cm at the clamping part of the temple 2, the pressure of the glasses 100 of this weight on the user's bridge of the nose can be effectively reduced, which conforms to the ergonomic design, and at the same time, the glasses 100 can be prevented from slipping or falling off, and the user has a good wearing experience.

[0045] Figure 4 An exploded view of the partial structure of the glasses using the first hinge assembly provided by the embodiments of the present disclosure is shown. As Figure 4 shown, the glasses 100 provided by some embodiments of the present disclosure include: a frame 3, temples 2, and an elastic member 13. The elastic member 13 is disposed between the frame 3 and the temples 2, and the elastic member 13 hinders the rotation of the temples 2 from the first position to the second position.

[0046] The elastic member 13 is used to provide a damping force for the outward expansion of the temples 2 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 member 13 can clamp the user's head with the two temples 2, so that the temples 2 can share the pressure of the nose pad of the glasses 100 and enable the glasses 100 to be stably worn on the user's head. During the process of the temples 2 opening relative to the frame 3, the elastic deformation amount of the elastic member 13 will increase, and the elastic member 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 direction opposite to the damping force. The elastic member 13 includes but is not limited to a torsion spring, a spring sheet, a tension spring, a compression spring, and a damping shaft.

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

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

[0049] In some embodiments of the present disclosure, the elastic member 13 of the glasses 100 may be a tension spring. At the first position, the tension spring is limited between the temple 2 and the frame 3 at a preset stretching length; during the process of the temple 2 opening to the second position, the stretching length of the tension spring continuously increases, thereby providing a damping force to hinder the rotation of the temple 2, so that the temple 2 applies a clamping force to the user's head in the direction opposite to the damping force.

[0050] In some embodiments of the present disclosure, the elastic member 13 of the glasses 100 may be a compression spring. At the first position, the compression spring is limited between the temple 2 and the frame 3 at a preset compression length; during the process of the temple 2 opening to the second position, the compression length of the tension spring continuously decreases, thereby providing a damping force to hinder the rotation of the temple 2, so that the temple 2 applies a clamping force to the user's head in the direction opposite to the damping force.

[0051] In some embodiments of the present disclosure, the elastic member 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; during the process of the temple 2 opening to the second position, the damping shaft can provide an increasing damping force, thereby providing a damping force to hinder the rotation of the temple 2, so that the temple 2 applies a clamping force to the user's head in the direction opposite to the damping force. Optionally, the damping shaft can also provide a constant damping force or a variable damping force.

[0052] In some embodiments of the present disclosure, the glasses 100 further include a hinge assembly 1, the hinge assembly 1 is provided between the temple 2 and the frame, the temple 2 is rotationally connected to the frame through the hinge assembly 1, the temple 2 and the frame 3 are connected through the hinge assembly 1, the hinge assembly 1 can realize the 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 member 13 is provided 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 Some embodiments of the present disclosure provide a first hinge assembly 1 as shown. As Figure 5 shown, the hinge assembly 1 may include: a first member 11 and a second member 12, and the first member 11 and the second member 12 are rotatably connected and can rotate relative to each other within a certain angle range. The first member 11 can be used to connect the temple 2, and the second member 12 is used to connect the frame 3, thereby realizing the connection between the temple 2 and the frame 3. When the first member 11 and the second member 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] Combined with Figure 4 and Figure 5 shown, the first member 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 included 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 also extend along a curve. For example, the first extension portion 111 and the second extension portion 114 extend along an arc. As Figure 2 shown, the second member 12 includes limiting portions 121 arranged oppositely. The oppositely arranged limiting portions 121 can accommodate the second extension portion 114 and can provide a space for the movement of the second extension portion 114. Optionally, there are two limiting portions 121, and the two limiting portions 121 are spaced apart and arranged oppositely. The first member 11 and the second member 12 are rotatably connected, and the second extension portion 114 of the first member 11 is located between the oppositely arranged limiting portions 121. The second extension portion 114 can rotate around the first axis, so that the temple 2 can rotate relative to the frame 3 around the first axis. The limiting portions 121 of the second member 12 limit the extreme positions of the relative rotation of the second extension portion 114, that is, limit the range of the relative rotation of the second extension portion 114. Thus, the relative rotation range between the temple 2 and the frame 3 can be limited.

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

[0057] As Figure 5As shown, the elastic member 13 is located between the first member 11 and the second member 12 and is used to provide a restoring force for the first extension 111 to rotate closer to the second member 12. Under the action of an external force, during the process of the temple 2 opening relative to the frame 3, the elastic member 13 located between the first member 11 and the second member 12 is deformed by the force. After the external force is removed, the elastic member 13 recovers its deformation, causing the temple 2 to close inward relative to the frame 3. The setting of the elastic member 13 provides a damping force for the outward expansion of the temple 2 relative to the frame 3, enabling the temple 2 to share the pressure on the nose pad of the glasses 100 and making the glasses 100 worn on the human body not easily fall off, thereby improving the wearing comfort.

[0058] In some embodiments of the present disclosure, the second member 12 may include two limiting portions 121 provided on the inner side and the outer side. Optionally, when expanding the temple 2, the elastic member 13 can be compressed by the second extension 114 so that the elastic member 13 provides a reverse restoring force, which can be achieved by arranging the elastic member 13 between the second extension 114 and the inner limiting portion 121. Alternatively, when expanding the temple 2, the elastic member 13 can be stretched by the second extension 114 so that the elastic member 13 provides a reverse restoring force, which can be achieved by arranging the elastic member 13 between the second extension 114 and the outer limiting portion 121. In some embodiments of the present disclosure, the elastic member 13 is located between the second extension 114 and any one of the limiting portions 121 of the second member 12. When the first extension 111 rotates away from the second member 12, the second extension 114 acts on the elastic member 13 to cause the elastic member 13 to deform. For example, the second extension 114 can compress or stretch the elastic member 13, causing the elastic member 13 to deform or increasing the amount of deformation of the elastic member 13. Thus, a restoring force for the first extension 111 to rotate in the direction closer to the second member 12 is provided by the elastic member 13.

[0059] It can be understood that the "inner limiting portion 121" in the above text can be understood as the limiting portion 121 close to the human face when the glasses 100 are in a worn state. The "outer limiting portion 121" can be understood as the limiting portion 121 away from the human face when the glasses 100 are in a worn state.

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

[0061] In an alternative 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 define the position of the second extension portion 114. The distance between the two connecting arms 122 is slightly greater than the width of the second extension portion 114, so as to cooperate with the two limiting portions 121 to limit that the second extension portion 114 can only swing within the accommodating space.

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

[0063] In some alternative embodiments, as Figure 4 shown, the first rotational connection portion 113 may include a connection shaft 1132. The connection 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 connection shaft. The axial direction of the connection shaft 1132 is the first axial direction. Optionally, the connection shaft 1132 and the first component 11 may be detachable split parts; or, the connection shaft 1132 and the first component 11 may also be integrally formed.

[0064] In some alternative embodiments, as Figure 5 and Figure 6 shown, the first rotational connection portion 113 may include a connection post 1131. The connection post 1131 is disposed at the corner between the first extension portion 111 and the second extension portion 114. The connection post 1131 has a post hole 1131a. The connection shaft 1132 may be fixedly or rotatably connected to the post hole 1131a. A first connection hole 1221 may be provided on the connecting arm 122 of the second component 12. The connection shaft 1132 is inserted into the post hole 1131a and the first connection hole 1221. Thus, the second component 12 can be rotatably connected to the connection 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: There is an angle between the lever arm of the temple 2 and the lever arm of the elastic member 13. As Figure 7 shown in the force diagram of the first hinge assembly 1 using a torsion spring. The clamping force provided by the temple 2 is F', and the lever 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 lever arm of the damping force F is L.

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

[0071] Figure 8 shows the structure of the second hinge assembly 1 provided in some embodiments of the present disclosure. Figure 9 shows the force diagram of the second hinge assembly provided in the embodiments of the present disclosure. The second hinge assembly 1 includes a first component 11 and a second component 12. 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 stud provided at the end of the frame 3. The first component 11 and the second component 12 are hingedly connected, and compression spring positioning posts are provided on both the first component 11 and the second component 12. The elastic member 13 can be a compression spring, and both ends of the compression spring are respectively sleeved on the compression spring positioning posts on the first component 11 and the second component 12. The clamping force provided by the temple 2 is F', and the lever 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 prevent the second component from rotating relative to the first component, and the lever arm of the damping force F is d. As Figure 9 shown, the lever arm d of the elastic member 13 is located on the extension line of the lever arm d' of the temple 2; the lever arm d of the elastic member 13 is located on the frame. The lever arm d' of the temple 2 and the lever arm d of the frame 3 are respectively located on both sides of the rotation center of the temple 2.

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

[0073] The spectacle frame 3 and each temple 2 are connected by two hinges. Two second connection seats 22 are arranged on the temple 2 in the width direction, two first connection seats 33 are arranged at the end of the spectacle 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 body 14, a second rod body 15 and an elastic member. The elastic member can be a tension spring 17. The second rod body 15 is connected to the first rod body 14, and a rotating shaft hole 141 is arranged on the first rod body 14. A sliding ring 16 and a tension spring 17 are sleeved on the second rod body 15. A plugging and blocking piece is arranged at one end of the second rod body 15 away from the first rod body 14. The tension spring 17 is located between the sliding ring 16 and the plugging and blocking piece. A limiting groove 161 is arranged on the sliding ring 16. The second connection seat 22 has a through hole 23 and a threaded hole 24 communicating with the through hole 23. The second rod body 15 of the hinge is inserted into the through hole 23, and a limiting screw 18 passes through the threaded hole 24 on the second connection 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 connection seat 33 can be fixed to the main body of the spectacle frame 3 through a rotating shaft seat screw 35. A rotating shaft screw 34 passes through the first connection seat 33 and penetrates through the rotating shaft hole 141 on the first rod body 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 end of the spectacle frame 3 change. The sliding sleeve can slide on the second rod body 15 to meet the above position change relationship. The arrangement of the tension spring 17 on the hinge ensures that when the temple 2 is opened or folded, the relative positions of the temple 2 and the spectacle frame 3 are relatively stable. When the temple 2 is opened, the tension spring 17 on the hinge assembly 1 generates elastic deformation and applies it to the temple 2, so that the temple 2 generates 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, that is, the damping force F provided by the tension spring to prevent the relative rotation of the second component with respect to the first component, and the force arm of the damping force F is d. As Figure 9 shown, the force arm d of the elastic member 13 of the structure of the third hinge assembly 1 is collinear with the force arm d' of the temple 2, and the force arm d of the elastic member 13 is located on the temple 2. The force arm of the temple 2 and the force arm of the elastic member 13 are 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 member 13 mentioned above are all equivalent force arms.

[0076] The following exemplarily provides a parameter table corresponding to the case where the elastic member 13 adopts a torsion spring scheme 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 spring torsion angle <![CDATA[θ1 = 66.7° to 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 portion of the temple 2 at a distance of 8 cm (±0.5) from the rotation axis, the variation range of the clamping force (F') is set to be 0.25 (±0.02) kgf (corresponding to the temple at 85°) to 0.3 (±0.02) kgf (corresponding to the temple at 105°), and the corresponding torque range is 1.72 kgf·cm to 2.72 kgf·cm. The torque T range of the torsion spring selected is 2.0 (±0.2) kgf·cm to 2.5 (±0.2) kgf·cm;

[0079] The relevant calculation formulas of the torsion spring are as follows:

[0080] Elastic force:

[0081] Torque: T (kgf·cm) = F * L;

[0082] Where: k - elastic coefficient, (kgf / cm degree);

[0083] The length of the torsion arm. According to the structural space, the optional length of the torsion arm L is 0.5 cm to 0.7 cm. For example, 0.6 cm can be selected. The value range of k is 0.036 kgf / degree to 0.05 kgf / degree. θ - the angle of torsion. According to the formula F = T1 / L = k * θ, F1 = 2.0 / 0.6 = k * θ1, and the value range of the angle of torsion θ1 at the first position is 66.7° to 92.6°. When the elastic member 13 uses a torsion spring, when the temple 2 is in the first position, the torsion spring has a first angle of torsion compared with the natural state, and the value range of the first angle of torsion is 66.7° to 92.6°. Thus, when the temple 2 leaves the first position, the damping force of the torsion spring can be immediately converted into the clamping force at the clamping portion of the temple 2, so that users with a 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 alternative embodiments of the present disclosure, as Figure 5 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 angle of torsion within the range of 66.7° to 92.6°.

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

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

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

[0088] When the elastic member 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 embodiments 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 embodiments of the present disclosure, the effective number of turns can be selected as 3 turns. The mean diameter of the torsion spring is greater than or equal to 2 mm. Limited by the forming process of the torsion spring, for a torsion spring with a wire diameter of more than 0.85 mm, the inner diameter should be greater than 2 mm. In this disclosure example, an inner diameter of 2.5 mm is selected, that is, the mean diameter is 3.35 mm. The material of the torsion spring is stainless steel, and the modulus of rigidity can be 19400.

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

[0090] By selecting a suitable torsion spring, the damping force of the torsion spring can be converted into the clamping force of the temple in a limited space, reducing the pressure of the temple on the nose bridge, and making the clamping force of the two temples 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 value of k is obtained as 0.046 kgf / degree, meeting the above requirements.

[0093] Among them, θ - the torsion angle. According to the formula F = T / L = k*θ, F1 = 2.0 / 0.6 = 0.046*θ, the first torsion angle can be obtained as 73° (i.e., θ1 = 73°), corresponding to the angle of 85° between the temple 2 and the horizontal. The second torsion angle of the torsion spring after outward expansion of 20° is 93° (i.e., θ2 = 93°), corresponding to the angle of 105° between the temple 2 and the horizontal. F2 = k*θ2 = 4.28 kgf, T2 = F2*L = 4.28*0.6 = 2.57 kgf·cm, meeting 2.5(±0.2) kgf·cm. F1’ = T1 / d’ = 2.0 / 8 = 0.25 kgf, F2’ = T2 / d’ = 2.57 / 8 = 0.32 kgf, meeting the clamping force standard of 0.25(±0.02) kgf to 0.3(±0.02) kgf.

[0094] See Figure 5As shown, some embodiments of the present disclosure provide a schematic structural view of a hinge assembly 1. The hinge assembly 1 is used for hingedly connecting the frame and the temple 2 of the glasses 100. 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. Among them, the first component 11 and the second component 12 are rotatably connected. 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 disposed between the first component 11 and the second component 12, and is used to provide a first moment for keeping the second component 12 in the first position, and a second moment for rotating the second structural member from the second position towards the first position; wherein, the ratio of the second moment to the first moment 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 the position where the second component 12 is in a natural open state. The second position may be the position where the second component 12 is at the maximum opening angle.

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

[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 included angle; when the second component 12 is located at the second position, the first component 11 and the second component 12 have a second included angle; the difference between the first included angle and the second included angle is 15°-25°.

[0098] During the process of the second component 12 opening from 15 degrees to 25 degrees, the clamping force exerted by the temple 2 on the user's head does not increase significantly, and the clamping force felt by the user also does not change significantly, so that users with different head circumferences can all have a comfortable wearing experience. In the embodiments of the present disclosure, when the second component 12 opens 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.

[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, it can effectively reduce the pressure of the glasses on the user's nose bridge, conform to the ergonomic design, and at the same time prevent the glasses from slipping or falling off, and the user has a good wearing experience.

[0100] In some embodiments of the present disclosure, the elastic member 13 includes a torsion spring. When the second member 2 is in the first position, the torsion spring has a first torsional angle compared to its natural state, and the first torsional angle is greater than or equal to 66.7 degrees and less than or equal to 92.6 degrees. Thus, when the second member 2 just leaves the first position, the damping force of the torsion spring can be immediately converted into the clamping force of the clamping portion of the temple 2, so that users with a smaller head circumference 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 member 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 included angle and the first included angle, and the value of the elastic coefficient is greater than or equal to 0.036 kgf / degree and less than or equal to 0.05 kgf / degree.

[0102] In some embodiments of the present disclosure, the elastic member 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 mean 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 temple within a limited space, reducing the pressure of the temple on the nose bridge, and the clamping force of the two temples does not increase significantly within a sufficient clamping space, providing a comfortable experience for users with different head circumferences.

[0104] The above description has been given for purposes of illustration and description. In addition, this description is not intended to limit the embodiments of the present disclosure to the forms disclosed herein. Although multiple example aspects and embodiments have been discussed above, those skilled in the art will recognize certain variations, modifications, changes, additions, and sub-combinations thereof.
