Description

Shaft assembly and glasses

[0001] This disclosure claims priority to the Chinese patent application filed with the State Intellectual Property Office on October 20, 2023, with application number CN202311370165.3 and invention name “Hinge Assembly and Glasses,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0002] The present disclosure relates to the technical field of wearable devices, and in particular to a hinge assembly and glasses. Background Art

[0003] A rotating shaft assembly is typically used to connect two relatively movable structural members. To increase the relative motion damping force between the two structures, an elastic component is typically installed on the rotating shaft of the rotating shaft assembly. This elastic component provides a damping force against the relative outward expansion of the two structural members. However, the space at the rotating shaft is typically small. Installing the elastic component there complicates the structure and is not conducive to the layout of the elastic component, resulting in limited damping force.

[0004] For example, the hinge assembly used to connect the frame and temples in glasses has a small space at the hinge. Furthermore, elastic components are usually integrated into the hinge, which complicates the structure and is not conducive to the layout of the elastic components, resulting in limited clamping force provided by the hinge assembly.

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the 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.

[0025] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0027] In some optional embodiments, a rotating shaft assembly can connect the first structural member and the second structural member, and can coordinate the relative rotation of the first structural member and the second structural member.

[0028] Optionally, the first and second structural members may be temples and frames, respectively, i.e., the frame and temples are connected via the aforementioned shaft assembly. The shaft assembly can coordinate relative rotation between the frame and temples. For example, the shaft assembly can provide a certain damping force when the temples are extended and retracted.

[0029] In some optional embodiments, taking the first and second structural members as temples and frames as an example, as shown in FIG1 , a shaft assembly 1 is disposed between the frame 3 and the temples 2, and the shaft assembly 1 is connected to the frame 3 and the temples 2, respectively, so that the temples 2 can rotate relative to the frame 3 to adjust the angle of the temples 2. FIG1 shows a schematic structural diagram of eyeglasses 100 provided in some embodiments of the present disclosure. It is understood that the first structural member is not limited to the temples 2, and the second structural member is not limited to the frame 3, that is, the shaft assembly 1 is not limited to connecting the frame 3 and the temples 2.

[0030] Figure 1 shows a schematic diagram of the structure of eyeglasses 100 provided in some embodiments of the present disclosure; Figure 2 shows an exploded view of a portion of the structure of eyeglasses 100 provided in some embodiments of the present disclosure; and Figure 8 shows a schematic diagram of the structure of the hinge body 11 of eyeglasses 100 provided in some embodiments of the present disclosure. The hinge assembly 1 may include a hinge body 11, which includes a first extension 111 and a second extension 112. The first extension 111 and the second extension 112 are connected and form an angle between them. The second extension 112 has a connecting portion that can be used to connect to a first structural member. For example, the first structural member may be a temple, and the connecting portion of the second extension 112 can be connected to the temple 2, as shown in Figure 2. One of the first extension 111 and the second extension 112 is provided with a rotational connection portion 11211 for connecting to the second structural member. The elastic member 12 may be located between the first extension 111 and the second structural member. For example, the first structural member may be a temple, and the connecting portion of the second extension 112 can be connected to the temple, as shown in Figure 2. In the solution provided in the embodiment of the present application, the first structural member and the second structure can achieve angle adjustment.

[0031] In some optional embodiments, the elastic component 12 and the rotating connection portion can be spaced apart. This eliminates the need for the elastic component 12 to be sleeved onto the rotating shaft. Furthermore, the spacing between the elastic component 12 and the rotating shaft facilitates the layout of the various components in the rotating shaft assembly 1. Furthermore, in the solutions provided in the embodiments of the present application, the placement of the elastic component 12 is not interfered with by the rotating shaft, making it easy to deploy larger, more numerous, or differently shaped elastic components 12, thereby increasing the elastic force and improving product performance.

[0032] In some optional embodiments, the shaft assembly 1 may include a shaft body 11, the shaft body 11 includes a first extension portion 111 and a second extension portion 112 connected to each other, and an angle is formed between the first extension portion and the second extension portion; the second extension portion is connected to the first structural member; the shaft assembly 1 also includes a rotating connection portion, and the shaft body and the second structural member are rotatably connected through the rotating connection portion; the shaft assembly 1 also includes an elastic component, which is located between the oppositely arranged surfaces in the first extension portion and the second structural member, and the oppositely arranged surfaces can be perpendicular to the rotating surface of the rotating connection portion.

[0033] In some optional embodiments, the shaft assembly 1 may include a shaft body, an elastic component, and a rotating connection portion; the shaft body 11 includes a first extension portion 111 and a second extension portion 112 connected to each other, and an angle is formed between the first extension portion and the second extension portion; the second extension portion 112 is connected to the first structural member, and the shaft body is rotationally connected to the second structural member via the rotating connection portion; when the first structural member drives the second extension portion 112 to rotate around the rotation axis of the rotating connection portion via the first extension portion, the distance between the surfaces of the first extension portion that are opposite to the second structural member changes, thereby compressing or releasing the elastic component. The two oppositely disposed surfaces may be surfaces of the first extension portion and the second structural member that can contact the elastic component.

[0034] In some optional embodiments, FIG2 shows a structural diagram of the coupling between the shaft assembly 1, the frame 3, and the temple 2, respectively, in the glasses 100 provided in some embodiments of the present disclosure, and FIG8 shows a schematic structural diagram of the shaft body 11 provided in some embodiments of the present disclosure. An abutment portion 111a is provided at one end of the first extension portion 111 of the shaft body 11 facing away from the second extension portion 112, and a rotational connection portion 11211 is located between the abutment portion 111a and the connection portion (the connection portion includes a fixing hole 1122). When the shaft body 11 is connected to the second structural member, the elastic member 12 is located between the abutment portion 111a and the second structural member.

[0035] Optionally, the first extension portion 111, the second extension portion 112, and the abutment portion 111a may extend in three different directions in space. For example, the first extension portion 111 may extend in the longitudinal direction of the second structural member connected to the shaft assembly, the second extension portion 112 may extend in the longitudinal direction of the first structural member connected to the shaft assembly, and the abutment portion 111a may extend in the transverse direction of the second structural member connected to the shaft assembly.

[0036] It should be understood that the term "rotating connection portion 11211 is located between the abutment portion 111a and the connecting portion" does not mean that the rotating connection portion 11211 is located within the line segment connecting the abutment portion 111a and the connecting portion. Rather, it should be understood that the abutment portion 111a, the rotating connection portion 11211, and the connecting portion are sequentially spaced apart along the direction in which the physical structure of the shaft body 11 extends. Along the direction in which the physical structure of the shaft body 11 extends, the rotating connection portion 11211 is spaced apart from both the abutment portion 111a and the connecting portion.

[0037] As shown in Figures 1 and 8, the rotating connection portion 11211 can be located at the corner formed by the first extension portion 111 and the second extension portion 112, while the abutting portion 111a is located at the end of the first extension portion 111 away from the rotating connection portion 11211. That is, the rotating connection portion 11211 and the abutting portion 111a are respectively arranged at the two ends of the first extension portion 111. The distance between the rotating connection portion 11211 and the abutting portion 111a is large, so that the rotating shaft assembly 1 occupies a larger space, which is conducive to the dispersed arrangement of the various components in the rotating shaft assembly 1 and facilitates the layout of the rotating shaft assembly 1. In addition, the solution disclosed in the present application facilitates the arrangement of the elastic component 12. The elastic component 12 and the abutting portion 111a cooperate to make the distance between the elastic component 12 and the rotating connection portion 11211 larger, and the rotating connection portion 11211 will not interfere with the arrangement of the elastic component 12, simplifying the structure at the rotating connection portion 11211 and reducing the difficulty of assembling the rotating shaft assembly 1.

[0038] In some optional embodiments, the elastic component 12 is limited by at least one of the abutting portion 111 a and the second structural component, and the shaft body 11 can rotate around the rotating connection portion 11211 so that the abutting portion 111 a compresses or releases the elastic component 12 .

[0039] It should be noted that the elastic component 12 can only cooperate with the top portion 111a. Alternatively, the elastic component 12 can also only cooperate with the second structural member. Alternatively, the elastic component can also cooperate with both the top portion 111a and the second structural member. Regarding the definition of "limiting", it can be understood that the elastic component 12 elastically presses against at least one of the top portion 111a and the second structural member to achieve fixed limiting by elastic force. It can also be understood that a specific limiting matching structure is provided in the top portion 111a and the second structure, and the elastic component 12 can be connected to the limiting matching structure. The limiting matching part limits the elastic component 12 to prevent the elastic component 12 from falling off. The limiting matching structure can be any one of a protrusion (such as a limiting column) and a groove. Of course, the limiting matching structure can also be other structures, and there is no unique limitation here.

[0040] In some optional embodiments, as shown in Figures 2 and 8, the rotating connection portion 11211 may include a connecting shaft 11211b, and after the connecting shaft 11211b is fixedly connected to the rotating shaft body 11, the connecting shaft 11211b may be connected to the second structural member. The second structural member can rotate around the connecting shaft 11211b. For example, the connecting shaft 11211b and the rotating shaft body 11 can be integrally formed, and the second structural member can be provided with a hole that is sleeved on the connecting shaft 11211b so that the second structure can be rotatably connected to the connecting shaft 11211b. For another example, the connecting shaft 11211b and the rotating shaft body 11 can also be detachable separate parts, and the rotating connection portion 11211 may include a connecting hole provided on the rotating shaft body 11, and the end of the connecting shaft 11211b can be fixedly or rotatably connected to the connecting hole. For another example, the end of the connecting shaft 11211b can be connected to the rotating shaft body 11 by riveting, and the connecting shaft 11211b can also be locked to the rotating shaft body 11 by adding screws to the bottom.

[0041] In some optional embodiments, Figure 7 illustrates the mating structure of the rotating shaft assembly and the second structural member. The second structural member in Figure 7 may be a spectacles frame. As shown in Figures 2 and 7 , two connecting arms 1121 may be provided at the end of the second extension 112 remote from the first structural member. The two connecting arms 1121 may be spaced apart along the width of the second extension 112, or arranged perpendicularly to the length of the second extension. A storage space for the second structural member may be formed between the two connecting arms 1121, which may be used to accommodate the second structural member. As shown in Figures 2 and 7 , one end of the spectacles frame 3 may be positioned in the storage space formed by the two connecting arms 1121. At least one of the two connecting arms 1121 is provided with a second connecting hole 11211a of the rotating connection 11211, to which the connecting shaft 11211b of the rotating connection 11211 is connected. The first extension 111 is connected to at least one of the connecting arms 1121.

[0042] Two connecting arms 1121 may be provided at one end of the second extension 112 away from the first structural member (e.g., the temple). The two connecting arms 1121 are spaced apart, forming a storage space between the two connecting arms 1121 to accommodate a portion of the second structural member. Each of the two connecting arms 1121 may be formed with, for example, a spherical protrusion as a rotational connection portion 11211. The second structural member may be provided with a recess that cooperates with the spherical protrusion on the connecting arm 1121 to enable the second structural member to rotate about the rotational connection portion 11211. Alternatively, only one of the two connecting arms 1121 may be provided with the rotational connection portion 11211. For example, one of the two connecting arms 1121 may be provided with a second connecting hole 11211a, which may be fixed to a connecting shaft 11211b to form the rotational connection portion 11211. Alternatively, both connecting arms 1121 may form the rotational connection portion 11211. When the two connecting arms 1121 jointly form a rotating connecting part 11211, the rotating connecting part 11211 may include a connecting shaft 11211b and second connecting holes 11211a respectively arranged on the two connecting arms 1121, the connecting shaft 11211b passes through the second structural member and its two ends are respectively fixedly connected to the second connecting holes 11211a of the corresponding connecting arms 1121.

[0043] In some optional embodiments, as shown in FIG8 , the first extension portion 111 can be connected to one of the two connecting arms 1121. The angle between the first extension portion 111 and the second extension portion 112 can be set according to the size of the angle to be formed between the first structural member and the second structural member. For example, the first extension portion 111 and the second extension portion 112 can be approximately perpendicular, and the first extension portion 111 is connected to one of the two connecting arms 1121 of the second extension portion 112. The connecting arm 1121 can be a sheet, and the first extension portion 111 can also be a sheet. The first extension portion 111 and the connecting arm 1121 are connected, and the two can be located in the same plane. Optionally, a hollow groove can be provided on the first extension portion 111, which is beneficial for reducing the weight of the shaft assembly 1. The hollow groove on the first extension portion 111 can be triangular, which reduces the impact on the structural strength of the first extension portion 111.

[0044] In some optional embodiments, as shown in conjunction with FIG2 and FIG8 , the abutment portion 111a includes an end portion of the first extension portion 111 extending in a first direction to form a baffle. The first direction is parallel to the connecting axis 11211b of the rotating connection portion 11211. The first direction is the direction indicated by arrow N in FIG8 .

[0045] Figure 6 shows a diagram of the matching structure of the rotating shaft assembly and the second structural member. In Figure 6, the elastic component is in a released state. Figure 7 shows a diagram of the matching structure of the rotating shaft assembly and the second structural member. In Figure 7, the elastic component is in a compressed state. The first extension portion 111 may include a main body portion, which may be sheet-shaped. The main body portion and the connecting arm 1121 are located in the same plane, and the baffle may be perpendicular to the main body portion. The elastic component 12 may be located between the baffle and the second structural member. During the rotation of the rotating shaft assembly 1 around the central axis of the rotating connection portion 11211, the baffle will be driven to move, squeezing or releasing the elastic component 12 through the baffle. The central axis of the rotating connection portion 11211 can be understood as the center line of the connecting shaft 11211b of the rotating connection portion 11211.

[0046] In some optional embodiments, as shown in FIG6 , the baffle can be located at the edge of the main body away from the second extension portion 112, thereby allowing the main body to retain a relatively large continuous planar structure, which can conveniently support the elastic member 12. One end of the elastic member 12 along the deformation direction can be supported on the main body and can also abut against the baffle, thereby stabilizing the end of the elastic member 12 and improving the stability and reliability of the shaft assembly.

[0047] The elastic component 12 is supported on the surface of the main body so that it will not rotate and fall off. At the same time, the main body also serves to connect the top portion 111a to the second extension portion 112. Therefore, when the elastic component 12 is compressed, the main body is the concentrated force area. The sheet structure of the main body can improve the structural strength and reduce the deformation of the shaft body 11 when the elastic part 12 is compressed.

[0048] In some optional embodiments, as shown in Figures 2, 6, 7, and 8, a stopper 111b may be provided on the top portion 111a for interlocking with the elastic member 12. The elastic member 12 and the stopper 111b interlock and cooperate with each other, preventing them from falling off easily, thereby improving stability and reliability.

[0049] In some optional embodiments, when the abutting top portion 111a is a baffle, the limiting portion 111b can be a convex column protruding from the surface of the baffle, and one end of the elastic component 12 can be limited on the convex column. As shown in the structure of Figure 9, when the elastic component 12 is a coil spring, one end of the elastic component 12 can be sleeved on the convex column. As shown in Figure 2, when the elastic component 12 is an elastic sheet, a limiting hole can be provided on the elastic sheet, and the convex column can be provided through the limiting hole. The limiting portion 111b can also be a groove provided on the surface of the baffle, and one end of the elastic component 12 can be limited in the groove. Here, there is no unique limitation on the specific form of the limiting portion 111b.

[0050] In some optional embodiments, the first extending portion 111 , the second extending portion 112 , the abutting portion 111 a and the limiting portion 111 b in the rotating shaft assembly 1 may be an integrally formed structure.

[0051] Three possible implementation schemes of the elastic member 12 are provided below:

[0052] Solution 1: As shown in Figures 2 and 5, the elastic component 12 can be a metal spring. The metal spring can include two springs 121, and one end of the two springs 121 is connected, and the other ends of the two springs 121 are separated. The two springs 121 of the elastic component 12 can be integrally formed, and the elastic component 12 is roughly V-shaped, U-shaped or R-shaped. The separated end of the above-mentioned metal spring is away from the rotating connection part (reference mark). When the top part 11a squeezes the separated end of the two springs 121 so that the two springs 121 are close to each other, the elastic component 12 can apply a reverse elastic force to the external structure. At least one of the two springs 121 is limited at the separated end. For example, a limiting hole can be provided at one end of the spring 121 that cooperates with the baffle, and the spring 121 can be mounted on the boss on the baffle through the limiting hole.

[0053] Solution 2: Figure 9 shows a schematic diagram of the mating structure of the rotating shaft assembly 1 and the second structural member. The elastic member 12 is a coil spring, with at least one of its ends in the direction of elastic compression being limited. For example, a protruding shaft can be provided on the baffle, one end of the coil spring can be sleeved onto the protruding shaft, and the other end of the coil spring can directly abut against the second structural member.

[0054] Solution 3: Figure 10 shows a schematic diagram of the mating structure of the shaft assembly 1 and the second structural member. The elastic component 12 can also be a torsion spring, with at least one of the two torsion arms of the torsion spring being limited. The opening direction of the torsion spring can also be away from the rotating connection portion (reference numeral). The two torsion arms of the torsion spring can respectively abut the baffle and the second structural member. During the rotation of the shaft assembly 1 relative to the second structural member, the two torsion arms move closer or farther away to adjust the elastic force.

[0055] In some optional embodiments, when the aforementioned hinge assembly 1 is applied to a pair of glasses 100, the first structural member may be the temple 2 of the glasses 100, and the second structural member may be the frame 3 of the glasses 100, as shown in FIG1 . The hinge body 11 in the hinge assembly 1 is rotatably connected to the frame 3 via a rotating connection 11211, and the second extension 112 of the hinge body 11 is connected to the temple 2. The elastic member 12 may be located between the frame 3 and the abutment portion 111a, so that the temple 2 can drive the hinge body 11 to rotate about the rotating connection 11211, thereby causing the abutment portion 111a to compress or release the elastic member 12. In the disclosed embodiment, the hinge assembly 1 connects the temple 2 and the frame 3. While ensuring that the hinge assembly 1 can provide a clamping force when the user wears the glasses, it is sufficient to simply rotatably connect the frame 3 to the rotating connection 11211. There is no need to provide studs at either end of the frame 3, nor is there a need to use studs to secure the elastic member 12, thereby simplifying the structure of the frame 3.

[0056] In some optional embodiments, as shown in Figures 1 and 2, the extension direction of the second extension portion 112 is substantially parallel to the length direction of the temple 2, and the stop portion of the first extension portion 111 is movable in the thickness direction of the frame 3 to compress or release the elastic component 12. The first extension portion 111 and the second extension portion 112 are substantially perpendicular to each other, and the first extension portion 111 and the second extension portion 112 may also form an obtuse angle slightly greater than 90 degrees. The angle of the first extension portion 111 and the second extension portion 112 may be adapted to the angle required between the frame 3 and the temple 2 when the temple 2 is in the open state. When the temple 2 drives the second extension portion 112 to rotate, the first extension portion 111 swings along the thickness direction of the frame 3 to squeeze or release the elastic component 12, and the reaction force of the elastic component 12 provides a clamping force for the temple 2. It should be noted that, in the embodiment of the present application, the thickness direction of the frame 3 can be referred to the direction indicated by the arrow T in FIG1 , the height direction of the frame can be referred to the direction indicated by the arrow H in FIG1 , and the width direction of the frame can be referred to the direction indicated by the arrow W in FIG1 .

[0057] In some optional embodiments, as shown in conjunction with Figures 2 and 4 , two connecting arms 1121 are provided at one end of the second extension 112 away from the temple 2. The two connecting arms 1121 are spaced apart along the height direction of the frame 3, and a receiving space is formed between the two connecting arms 1121 to accommodate the upper edge of the frame 3. The frame 3 can be positioned between the two connecting arms 1121, and at least one of the two connecting arms 1121 is provided with a rotating connection portion 11211, connecting the frame 3 to the rotating shaft body 11 via the rotating connection portion 11211. The first extension 111 is connected to at least one of the two connecting arms 1121.

[0058] As shown in conjunction with Figures 2, 6, and 8, the two connecting arms 1121 can each be provided with a rotational connection portion 11211, the rotational connection portion 11211 can be formed on only one of the two connecting arms 1121, or the two connecting arms 1121 can jointly form the rotational connection portion 11211. Optionally, when the two connecting arms 1121 jointly form the rotational connection portion 11211, the rotational connection portion 11211 can include a connecting shaft 11211b and connecting holes respectively provided on the two connecting arms 1121. Axial holes along the height direction of the frame 3 can be provided at both ends in the length direction of the frame 3, the connecting shaft 11211b passes through the axis holes at both ends of the frame 3, and the two ends of the connecting shaft 11211b are respectively fixed to the connecting holes of the two connecting arms 1121, so that the frame 3 can rotate around the connecting shaft 11211b of the rotational connection portion (reference numeral). It is understood that the axial holes in the frame 3 can be directly provided at both ends of the frame 3, or external structures can be provided at both ends of the frame 3, and the axial holes are then provided on the external structures. Here, there is no specific limitation on the specific arrangement of the axial holes at both ends of the frame 3 through which the connecting shaft 11211b passes.

[0059] In some optional embodiments, FIG3 shows a top view of glasses provided by an embodiment of the present disclosure. The frame 3 may include a hole 311, and the elastic component 12 is located within the hole 311. The hole 311 extends vertically through the frame 3. The abutting portion 111a may extend into the hole 311, and the elastic component 12 abuts against the abutting portion 111a and the inner wall of the hole 311, respectively.

[0060] The hole 311 provided in the frame 3 provides space for accommodating the elastic component 12, while the elastic component 12 does not occupy the structural space around the frame 3, thereby not affecting the overall structural layout of the frame 3. The cross-section of the hole 311 can be roughly triangular, which reduces the weight of the glasses while minimizing the impact on the structural strength of the frame 3.

[0061] As shown in Figures 2, 3, and 6, the hole 311 may include a first wall 3111 and a second wall 3112. It can also be understood that the first wall 3111 and the second wall 3112 may define the hole 311. When the glasses 100 are in the stowed state, the first wall 3111 is close to the temple 2, the second wall 3112 is away from the temple 2, and the elastic component 12 is located between the abutment portion 111a and the first wall 3111. The first wall 3111 and the second wall 3112 may serve as sidewalls of the hole 311. As shown in Figures 4 and 7, during the opening of the temple 2, the abutment portion 111a gradually moves toward the first wall 3111 to compress the elastic component 12. The elastic component 12 is engaged with one of the abutment portion 111a and the first wall 3111 to ensure that the elastic component 12 does not easily fall off. For example, a limiting portion 111b may be provided on the first wall surface 3111, and one end of the elastic member 12 is engaged with the limiting portion 111b, so that the elastic member 12 can be compressed when the abutting portion 111a moves toward the first wall surface 3111. The limiting portion 111b may also be provided on the abutting portion 111a. For example, when the abutting portion 111a serves as a baffle, the limiting portion 111b may be provided on the baffle and protrude from the baffle.

[0062] In some optional embodiments, the elastic component 12 may be a metal spring. The elastic component 12 may include two springs 121, one end of the two springs 121 is connected, and the other ends of the two springs 121 are separated. The two springs 121 of the elastic component 12 can be integrally formed, and the elastic component 12 is roughly V-shaped, U-shaped or R-shaped. The separated ends of the two springs 121 of the elastic component 12 respectively press against the baffle and the first wall 3111. A limiting hole can be provided on the spring 121 that contacts the baffle, and the spring 121 is sleeved on the limiting portion 111b on the baffle through the limiting hole. The limiting portion 111b on the baffle can clamp the limiting hole in the center of the spring 121, and the wall spring 121 is displaced. The thickness of the limiting portion 111b can be greater than that of the spring piece 121. The limiting portion 111b can be used to limit the maximum opening angle of the temple 2. When the temple 2 is opened to the maximum angle, the limiting portion 111b will abut against the other spring piece 121, thereby stopping the rotation of the temple 2. The disclosed embodiment does not require a stud on the frame 3 to fix the spring piece 121, nor does it require a stud to limit the maximum opening and closing angle of the temple 2.

[0063] The baffle can contact one side of the free end of the spring 121. When the temple 2 rotates, the baffle compresses the free end of the corresponding spring 121, bringing the two springs 121 closer together and reducing the angle between them. The elastic component 12 can exert a reverse elastic force on the baffle, thereby increasing the clamping force of the temple 2. Of course, the rebound force generated by the metal spring can also ensure that the temple 111b hovers at a certain angle when opened, even if the limit portion 111b does not reach the other spring 121. This allows the glasses disclosed in this application to adapt to users with different head dimensions.

[0064] As shown in Figure 7 , the baffle serves as a mounting surface for the elastic member 12 and also limits the minimum opening and closing angle of the temple 2. When elastic force is not required to maintain temple opening, the baffle can be parallel to and in contact with the second wall 3112. When the temple 2 is extended to a certain angle, the baffle contacts the second wall 3112, preventing further rotation of the temple 2, as shown in Figure 5 .

[0065] In some optional embodiments, the above-mentioned mirror frame 3 may include a front frame 32 and a crossbeam portion 31. The crossbeam portion 31 may be located at the upper edge of the front frame 32 and extend along the width direction of the front frame 32, and the width direction of the crossbeam portion 31 is the same as the thickness direction of the front frame 32. The thickness direction of the crossbeam portion 31 is the same as the height direction of the front frame 32. The hole portion 311 may be provided at the end of the crossbeam portion 31, and the hole portion 311 may pass through the crossbeam along the thickness direction of the crossbeam. The main body of the first extension portion 111 may be located on either side of the crossbeam along the thickness direction, and the baffle is perpendicular to the main body and extends into the hole portion 311.

[0066] In some optional embodiments, as shown in Figures 2, 6, and 8, the two connecting arms 1121 are located on the upper and lower sides of the crossbeam 31, respectively, with the first extension 111 proximate the lower side. The upper and lower sides of the crossbeam 31 are the surfaces of the crossbeam 31 arranged sequentially along the height direction of the mirror frame 3. As shown in Figures 2 and 8, the two connecting arms 1121 of the second extension 112 are located on either side of the crossbeam along its thickness direction. The crossbeam may be provided with a first connecting hole 312, through which the connecting shaft 11211b of the rotary connection 11211 passes, with both ends of the connecting shaft 11211b of the rotary connection 11211 connected to the connecting holes on the two connecting arms 1121. The main body of the first extension 111 is located on the lower side of the crossbeam, proximate the lower side of the crossbeam. The baffle is perpendicular to the lower surface of the crossbeam and extends into the hole 311.

[0067] In a possible embodiment, as shown in FIG4 , the first wall 3111 and the second wall 3112 are close to each other at one end of the beam portion 31 , and are separated at one end of the first wall 3111 and the second wall 3112 away from the end of the beam portion 31 .

[0068] In this embodiment, the width of the beam portion 31 gradually decreases from the middle to the two ends, forming a structure with narrowed ends. In order to adapt to the structural characteristics of the beam portion, the hole portion 311 is also set to a structure with a gradually narrowed width from the middle of the beam portion to the ends of the beam portion. The elastic component 12 is preferably a metal spring 121 with a V-shaped or R-shaped structure, and the opening of the elastic component 12 is facing the middle of the beam portion. The shape of the elastic component 12 matches the shape of the hole portion 311, making full use of the existing space in the beam portion. It can be seen that the hole portion 311 provided in the beam portion 31 not only plays a role in reducing weight, but the hole portion 311 can also cooperate with the shaft body 11 and the elastic component 12 of the shaft assembly to realize the shaft function, making full use of the existing space in the beam portion.

[0069] The force exerted on the temples 2 to expand laterally is converted into a longitudinal, backward force (when the temples 2 are extended, the springs 121 are compressed substantially along the width of the frame 3 in Figure 3 ). The force is applied to the center of the first wall 3111. Compared to applying force laterally to the beam 31, the hinge assembly of this embodiment redirects the force, is less likely to cause deformation of the beam, and eliminates the need for lateral position limiting. As the temples 2 continue to expand and the springs 121 continue to compress, the hinge assembly 1 can transition from the state shown in Figure 5 to the state shown in Figure 4 .

[0070] In one possible embodiment, a first connection hole 312 is provided on the crossbeam portion 31, and the hole portion 311 is located on the side of the first connection hole 312 that is away from the end of the crossbeam, as shown in FIG2 . The rotating connection portion 11211 includes a connecting shaft 11211b and a second connection hole 11211a provided on the connecting arm 1121. The connecting shaft 11211b passes through the second connection hole 11211a and the first connection hole 312 to connect the crossbeam portion 31 and the connecting arm 1121. The connecting shaft 11211b can be fixedly connected to the second connection hole 11211a and rotatably connected to the first connection hole 312. Therefore, the frame 3 can rotate about the connecting shaft 11211b, so that the first extension portion 11 of the rotating shaft body can drive the abutment portion 111a to move within the hole portion 311.

[0071] The hole portion 311 is arranged at the end position of the beam portion 31 along the length direction, so that the connecting arm 1121 of the second extension portion 112 is connected to the first connecting hole 312 through the connecting shaft 11211b. At the same time, the first extension portion 111 can extend toward the middle side of the beam and smoothly extend to the position of the hole portion 311.

[0072] In a possible embodiment, as shown in FIG2 , the second extension 112 is rotatably connected to the temple 2 via a connecting portion so as to swing in the height direction of the frame 3. The temple 2 is provided with a first tooth portion, and the protruding teeth of the first tooth portion are sequentially arranged along the width direction of the temple 2. The second extension portion is provided with a second tooth portion 1123 adapted to the first tooth portion. When the temple 2 rotates relative to the second extension 112, the first tooth portion can be driven to move relative to the second tooth portion 1123, changing the position of engagement with the second tooth portion 1123. In the disclosed embodiment, the temple 2 can be moved in two different directions, that is, the two temples 2 of the glasses 100 can be stretched outward (bent outward) to adapt to the head circumference of different wearers, thereby improving adaptability. In addition, the two temples 2 of the glasses 100 can also swing up and down to achieve up and down adjustment to adapt to the height of the ears of different wearers, thereby improving the usability of the glasses 100. Both the first and second tooth sections 1123 include multiple protruding teeth. By adjusting the temple 2 up or down, the first and second tooth sections 1123 can be engaged at different positions, adjusting the vertical swinging position of the temple 2. The connecting portion may include a fastener b, a disc spring a, a friction plate c, and a fixing hole 1122 provided on the second extension arm. One end of the fastener b can be passed through the disc spring a, the friction plate c, and the fixing hole 1122 provided on the second extension arm 112, and then connected to the temple 2. The disc spring a and friction plate c provide damping for the vertical swinging of the temple 2.
