Description

Technical Field

[0001] The present application relates to the technical field of glasses, and in particular to a hinge assembly and a glasses frame. Background Art

[0002] At present, in the structural design of the frame, in addition to being able to fold and store inward relative to the head, the temples also have the ability to bend and recover in other directions, so as to ensure that the temples can withstand loads in abnormal directions, maintain the integrity of the frame in unexpected bending, and extend its service life. For example, the temples can bend upward, downward, or inward relative to the head by extending and recovering the hinge assembly.

[0003] In the existing hinge assembly between the temple and the pile head, the spring is confined inside a semi-open shell and is passed through by a slide rod. In the process of bending the temple relative to the pile head, the slide rod slides relative to the shell and the spring, and the slide rod compresses the spring during the sliding process. The problems with this hinge assembly are: first, it is difficult to process. The interior of the semi-open shell is hollow, and holes are respectively opened at one end and the side. The hole at one end is for the slide rod to pass through, and the hole on the side is for the spring to be placed in and taken out. The other surfaces are not opened. The processing technology of the semi-open shell is complicated and the cost is high; second, the assembly is complicated. The spring needs to be passed through by the slide rod first, and then placed in the shell from the hole on the side in a compressed state. The assembly of the slide rod is relatively difficult, so the length of the slide rod is limited. In addition, in the frame, the overall volume of the hinge assembly itself is limited, which further increases the difficulty of processing and assembling the hinge assembly. Utility Model Content

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0050] It should be noted that when a component is referred to as being "fixed to" or "disposed on" another component, it may be directly or indirectly fixed or disposed on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings and is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation of this patent. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0051] In order to illustrate the technical solution described in this application, a detailed description is given below in conjunction with specific drawings and embodiments.

[0052] See also Figure 1 and Figure 2 As shown, the embodiment of the present application first provides a frame 200, which includes a frame 91, a stud 92, a hinge assembly 100 and a temple 93 connected in sequence. Figures 2 to 4 As shown, by means of the hinge assembly 100 , the temple 93 can be bent relative to the stump 92 and the frame 91 in at least two directions.

[0053] For ease of description, three directions are defined below: up and down, left and right, and front and back. Figure 1 , Figure 3 and Figure 4 As shown, the three directions are based on the user wearing the frame 200 (or glasses including the frame 200) normally and keeping his eyes level.

[0054] like Figure 3 As shown in , the right side temple 93 is bent upward relative to the frame 91; Figure 4 As shown in FIG, the right side temple 93 is bent outward relative to the mirror frame 91, that is, bent to the right.

[0055] Next, see Figures 5 to 8 As shown, the hinge assembly 100 of the present application will be described in detail.

[0056] like Figure 6 , Figure 7 and Figure 8 As shown, the hinge assembly 100 includes a housing 3 and a reset member 6. The reset member 6 is disposed in the housing 3. One end of the housing 3 is used to connect with the stud 92, and the other end is used to connect with the temple 93. Figure 2 and Figure 5 When the temple 93 is bent relative to the stump 92, the length of the housing 3 changes, thereby causing the length of the reset member 6 to change.

[0057] Specifically, see Figure 6 and Figure 7 As shown, the housing 3 includes a first frame 4 and a second frame 5 that can slide relatively along a first direction X. The first frame 4 includes a first connecting portion 41 for connecting with the stump 92, a first stopper 42 facing the temple 93, and a plurality of first rods 43; the two ends of each first rod 43 are respectively connected to the first connecting portion 41 and the first stopper 42, and the plurality of first rods 43 are arranged at intervals. In this way, a first space 40 is formed between the plurality of first rods 43, or the first space 40 is formed by enclosing the plurality of first rods 43. It can be understood that the enclosing here does not mean a closed enclosing.

[0058] See also Figure 6 and Figure 7 As shown, the second frame 5 includes a second connection portion 51 for connecting with the temple 93, a second stop portion 52 facing the stump 92, and a plurality of second rods 53, both ends of each second rod 53 are respectively connected to the second connection portion 51 and the second stop portion 52, and the plurality of second rods 53 are arranged at intervals. In this way, a second space 50 is formed between the plurality of second rods 53, or the second space 50 is formed by the plurality of second rods 53. It can also be understood that the enclosure here does not mean a closed enclosure.

[0059] Also, please refer to Figure 7 and Fig. 9As shown, the second limiting portion 52 includes two limiting ends 521 spaced apart in the second direction Y, and a slide groove 520 is formed between the limiting ends 521 and passes through along the second direction Y, that is, the slide groove 520 is connected to the second space 50 and the end face of the second limiting portion 52 away from the first connecting portion 41 along the second direction Y. In the embodiment of the present application, the width of the slide groove 520 is configured to allow at least the first connecting portion 41 of the first frame 4 to slide in the slide groove 520 along the first direction X and the third direction Z. Here, the width refers to the dimension in the second direction Y. The second direction Y and the third direction Z are respectively perpendicular to the first direction X, and the second direction Y and the third direction Z are inclined to each other.

[0060] Please refer to Figure 5 and Figure 6 As shown, the reset member 6 is disposed in the first space 40 and the second space 50, and its first end 61 is connected to the first limit portion 42, and the second end 62 is connected to the second limit portion 52. Here, the first end 61 and the second end 62 of the reset member 6 are respectively limited by the first limit portion 42 and the second limit portion 52, and the first end 61 cannot pass over the first limit portion 42 in one direction, and the second end 62 cannot pass over the second limit portion 52 in the first direction X.

[0061] The first frame 4 slides in the slide groove 520 along the first direction X, that is, the first frame 4 and the second frame 5 slide relative to each other in the first direction X, so that the plurality of first rods 43 are respectively located on the opposite sides of the second frame 5, and the plurality of second rods 53 are respectively located on the two sides of the first frame 4, that is, the first space 40 and the second space 50 intersect each other. Figure 8 As shown; since the relative sliding of the first frame 4 and the second frame 5 in the first direction X will be restricted by the reset member 6, when the first frame 4 slides along the third direction Z in the slide groove 520, the first frame 4 and the second frame 5 can be separated and combined while avoiding the reset member 6.

[0062] When the temple 93 is bent relative to the stud 92, with the mirror frame 91 and the stud 92 as reference, the second frame 5 slides relative to the first frame 4 along the first direction X, the second limit portion 52 approaches the first limit portion 42 along the first direction X, and the two ends of the reset member 6 approach each other, that is, the reset member 6 can be compressed. In this way, when the force that bends the temple 93 is canceled, under the action of the restoring force of the reset member 6, the second frame 5 slides in the opposite direction relative to the first frame 4 along the first direction X, the second limit portion 52 moves away from the first limit portion 42 along the first direction X, and the reset member 6 stretches until the temple 93 is restored to be flush with the stud 92.

[0063] It should be noted that the first direction X may be parallel to the front-rear direction, or, depending on the positional arrangement between the temple 93 and the stud 92, the first direction X may have a certain angle with the front-rear direction. However, in general, the first direction X is the compression direction and the restoring direction of the reset member 6 when the temple 93 is bent relative to the stud 92.

[0064] In an optional embodiment, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0065] Furthermore, when the first direction X is parallel to the front-rear direction, the second direction Y may be parallel to the left-right direction or may be inclined to the left-right direction.

[0066] The hinge assembly 100 provided in the embodiment of the present application has a housing 3 composed of a first frame 4 and a second frame 5 that can slide relatively along a first direction X and a third direction Z. The sliding of the first frame 4 and the second frame 5 along the first direction X realizes the compression of the reset member 6, and the sliding of the first frame 4 and the second frame 5 along the third direction Z realizes the combination and disassembly of the two. The processing and manufacturing of the first frame 4 and the second frame 5 can be simpler, and the assembly method can be simpler, which is conducive to reducing the cost and operation difficulty of the hinge assembly 100 and improving the operation efficiency.

[0067] Please refer to Figure 7 and Fig. 9 As shown, in one embodiment, the first frame 4 includes two first rods 43, and the two first rods 43 are spaced apart in the third direction Z; Figure 7 and Fig.10 As shown, the second frame 5 includes two second rods 53 , and the two second rods 53 are spaced apart in the second direction Y. Thus, the first frame 4 and the second frame 5 are substantially flat, which can further simplify the processing and manufacturing of the first frame 4 and the second frame 5 .

[0068] The surrounding side of the reset member 6 is provided with two first rods 43 and two second rods 53 arranged alternately, see Figure 6 and Figure 8 shown.

[0069] In other optional embodiments, the first frame 4 may include more than two first rods 43, and / or the second frame 5 may include more than two second rods 53, without affecting the relative sliding between the first frame 4 and the second frame 5 along the first direction X and the third direction Z. In general, the number of the first rods 43 and the second rods 53 should not be too large to ensure that the first frame 4 and the second frame 5 are easy to process.

[0070] Please refer to Figure 7 , Figure 8 and Fig. 9As shown, a first limiting column 411 is disposed on the first connection portion 41. The first limiting column 411 is located in the first space 40 and extends from the inner end surface of the first connection portion 41 toward the first limiting portion 42; see Figure 7 As shown, the second end 62 of the reset member 6 is provided with a second receiving groove 602 capable of receiving the first limiting column 411 .

[0071] The purpose of such a configuration is that, by inserting the first limiting column 411 into the reset member 6, the movement of the reset member 6 in other directions can be restricted, so that the reset member 6 is compressed along the first direction X, thereby preventing the reset member 6 from bending during the compression along the first direction X, thereby preventing the reset member 6 from failing to return smoothly.

[0072] The length of the first limiting column 411 should be less than the length of the first space 40, and here and in the following description, the length refers to the dimension along the first direction X. Optionally, the length of the first limiting column 411 should be less than half the length of the first space 40, or there is another size relationship between the length of the first limiting column 411 and the length of the first space 40. This can facilitate the installation of the reset member 6 in the first space 40 and the cooperation with the first limiting column 411.

[0073] See also Figure 7 and Figure 8 As shown, the first limiting column 411 extends along the first direction X, and has two side surfaces in the second direction Y, which can serve as guide surfaces 4111 for the two limiting ends 521 to slide. That is, when the second frame 5 moves away from the first frame 4 along the first direction X, the end surfaces of the two limiting ends 521 that are close to each other slide along the guide surfaces 4111 of the first limiting column 411, so that the sliding direction of the second frame 5 can be further maintained.

[0074] The second receiving groove 602 on the restoring member 6 may be a blind hole opened from the end surface of the second end 62 thereof, or may be a through hole penetrating the first end 61 and the second end 62 thereof.

[0075] In one embodiment, the reset member 6 is a spring, and the through space inside the spring can be used as the second accommodating groove 602 .

[0076] In another embodiment, the reset member 6 is an elastic column, and the second receiving groove 602 is a through hole or a blind hole opened on the column.

[0077] Please participate Figure 7 and Fig.10As shown, the second limiting portion 52 further includes at least one second limiting column 522, the second limiting column 522 is connected to the limiting end 521, and can be the inner side of the limiting end 521, the side close to each other, the second limiting column 522 is located in the second space 50, and extends toward the second connecting portion 51. In other words, the second limiting column 522 is located on at least one side of the first limiting column 411 along the second direction Y, and the second limiting column 522 is also located in the second accommodating groove 602 of the reset member 6.

[0078] This is equivalent to that a second limiting column 522 and a limiting end 521 form a hook-shaped structure, and the second limiting column 522 is inserted into the reset member 6 to compress the reset member 6 in a manner of hooking the reset member 6, which can further ensure the compression direction of the reset member 6.

[0079] In an optional embodiment, the second limiting pillar 522 is connected to the sides of the two limiting ends 521 that are close to each other.

[0080] The length of the second limiting column 522 is smaller than that of the first limiting column 411 , so as to facilitate its insertion into the reset member 6 and also facilitate the second limiting column 522 to slide along the guide surface 4111 of the first limiting column 411 .

[0081] In other optional embodiments, only the first limiting column 411 or only the second limiting column 522 may be provided on the housing 3 .

[0082] See also Figure 7 and Fig. 9 As shown, in one embodiment, a guide groove 420 is provided on one side of the first limiting portion 42 away from the first space 40 and is recessed along the first direction X. The height of the guide groove 420 is configured to allow the second connecting portion 51 to slide in. Here, the height refers to the dimension in the third direction Z.

[0083] In addition to guiding the sliding of the second frame 5 , the guide groove 420 can also limit the movement of the second frame 5 in other directions, for example, limit the movement of the second frame 5 in the third direction Z.

[0084] In one embodiment, see Fig. 9 As shown, since the first limiting portion 42 is generally in the shape of a plate and is perpendicular to the second frame 5, the guide groove 420 passes through the first limiting portion 42 in the second direction Y. This can simplify the processing and manufacturing of the guide groove 420 on the first limiting portion 42. In this way, the guide groove 420 cannot limit the movement of the second frame 5 in the second direction Y. However, since the aforementioned first limiting column 411 has been blocked between the two limiting ends 521 along the second direction Y, the movement of the second frame 5 relative to the first frame 4 in the second direction Y can be limited.

[0085] Please continue reading Figure 7and Fig. 9 As shown, in one embodiment, a third limiting column 421 is provided on one side of the first limiting portion 42 facing the first space 40; see Figure 7 As shown, the first end 61 of the reset member 6 is provided with a first accommodating groove 601 capable of accommodating the third limiting column 421. The third limiting column 421 can limit the first end 61 of the reset member 6 to prevent the first end 61 of the reset member 6 from bending in other directions.

[0086] Correspondingly, the first receiving groove 601 may be a blind hole opened from the end surface of the first end 61 thereof, or may be a through hole penetrating the first end 61 and the second end 62 thereof.

[0087] When the first accommodating groove 601 is a through hole passing through the first end 61 and the second end 62 thereof, it completely overlaps with the second accommodating groove 602. That is to say, at this time, the through hole passing through the first end 61 and the second end 62 of the resetting member 6 includes both the first accommodating groove 601 and the second accommodating groove 602.

[0088] The length of the third limiting column 421 can be set to be smaller, for example, smaller than the length of the first limiting column 411. This can reduce the difficulty of installing the reset member 6 in the first space 40 as much as possible, and is also conducive to the processing and manufacturing of the first frame 4.

[0089] In an optional embodiment, if Fig. 9 As shown, the length of the guide groove 420 is greater than the length of the first limiting portion 42, so that the guide groove 420 is partially formed on the third limiting column 421. The purpose of this arrangement is to reduce the length of the first limiting portion 42 while ensuring that the length of the guide groove 420 is sufficient, thereby reducing the overall length of the first frame 4 and the housing 3, and further reducing the space occupied by the hinge assembly 100 between the frame 200 and the stump 92.

[0090] See also Figure 7 , Figure 8 and Fig. 9 As shown, in one embodiment, the first connecting portion 41 of the first frame 4 is provided with a first connecting hole 410; see Figure 6 and Figure 7 As shown, the hinge assembly 100 further includes a connecting hook portion 7, which includes a connecting body 71 and a hook 72. Figure 5 , Figure 6 and Figure 7 The main body 71 is used to connect with the pile head 92 , and the hook 72 is used to cooperate with the first connecting hole 410 .

[0091] By setting the size and / or shape of the hook 72 and the first connection hole 410, for example, by designing the inner side surface of the hook 72 as a curved surface, and designing the inner side surface of the first connection hole 410 as a curved surface, etc., the hook 72 can be made to not be separated from the first connection hole 410 in the first direction X, and the cooperation between the hook 72 and the connection hole will not form a rotation in a specific direction, but can move relatively in any direction. That is, at this time, the first frame 4 can not only bend upward, downward, leftward and rightward relative to the hook 72, but also bend in other directions, such as upper left and lower right, etc. It can be said that the first frame 4 can be equivalent to the hook 72 to achieve 360-degree bending. This further improves the bending flexibility of the hinge assembly 100 and improves the ability of the frame 200 to withstand loads in more unexpected directions.

[0092] Since the hook 72 and the first frame 4 can be bent 360 degrees relative to each other, the hook 72 and the main body 71 can be fixedly connected or rotatably connected about at least one rotation axis.

[0093] Likewise, the main body 71 of the connecting hook 7 and the pile head 92 may be fixedly connected or rotatably connected about at least one rotation axis.

[0094] Since the first frame 4 is a flat plate structure substantially along the third direction Z, the first connecting hole 410 thereof may be a through hole arranged along the second direction Y. Figure 7 and Fig. 9 This facilitates the processing and manufacturing of the first connecting hole 410.

[0095] like Figure 5 , Figure 6 and Figure 7 As shown, in an optional embodiment, the main body 71 is provided with a third connecting hole 710, and the first pin 94 passes through the pile head 92 and the third connecting hole 710 to connect the pile head 92 with the connecting hook 7. At this time, the third connecting hole 710 can be selected as a through hole along the third direction Z, which is also convenient for the processing and manufacturing of the connecting hook 7.

[0096] The main body 71 and the pile head 92 may be fixedly connected, and the main body 71 cannot rotate around the first pin 94. Alternatively, the main body 71 may rotate around the first pin 94, which may further provide the hinge assembly 100 with flexibility.

[0097] In other embodiments, the first frame 4 can achieve rotational connection with the pile head 92 in other ways. For example, the first connection portion 41 of the first frame 4 can rotate around one rotation axis, or the first connection portion 41 can rotate around multiple rotation axes.

[0098] See also Figure 5As shown, in order to reduce the distance between the temple 93 and the stud 92, that is, to hide the hinge assembly 100 as much as possible, in one embodiment, a mounting groove 930 is provided on the side of the temple 93 facing the stud 92, and at least a portion of the first frame 4 and the second frame 5 is located in the mounting groove 930, so that when the temple 93 is flush with the stud 92, the hinge assembly 100 can be mostly or completely hidden in the first direction X, for example Figure 1 , Figure 3 and Figure 4 shown.

[0099] Please refer to Figure 7 , Figure 8 and Fig.10 As shown, the second connecting portion 51 is provided with a second connecting hole 510, and the second connecting hole 510 is connected to the temple 93 through the second pin 95. Since at least most of the second frame 5 is accommodated in the mounting groove 930, the second frame 5 can be optionally configured to be fixed in the mounting groove 930, that is, the second frame 5 cannot rotate relative to the temple 93 around the second pin 95. At this time, the size of the second frame 5 can be set to be substantially equal to, as equal as possible to, or even equal to the size of the mounting groove 930, so that the mounting groove 930 does not need to occupy too much space on the temple 93.

[0100] In one embodiment, the first frame 4 can be a metal part or a plastic part, depending on the design requirements of the bonding strength. The second frame 5 can be a metal part or a plastic part, depending on the design requirements of the bonding strength.

[0101] The first frame 4 can be an integrally formed part, such as a metal integrally stamped part, or a plastic integrally injection-molded part, etc. The second frame 5 can be an integrally formed part, such as a metal integrally stamped part, or a plastic integrally injection-molded part, etc.

[0102] The mirror frame 91 can be a metal part or a plastic part. The pile head 92 can be a metal part or a plastic part.

[0103] See below. Figures 11 to 14 As shown, the hinge assembly 100 provided in the embodiment of the present application is assembled according to the following steps:

[0104] Step 1, see Fig.11 As shown, the reset member 6 is slightly compressed and installed on the first frame 4, the first limiting column 411 enters the second accommodating groove 602, and the third limiting column 421 enters the first accommodating groove 601; the reset member 6 is released, and the reset member 6 extends and naturally rests on the side where the first connecting portion 41 and the second limiting portion 52 are close to each other.

[0105] Since in this step, only the first rod 43 of the first frame 4 surrounds the reset member 6 , at this time, the compression of the reset member 6 and the placement in the first space 40 will not cause obvious difficulties in operation.

[0106] Step 2, see Fig.12 As shown, the second frame 5 is moved along the third direction Z so that the two limit ends 521 are respectively located on both sides of the first connecting portion 41 on the first frame 4; at this time, the second rod 53 of the second frame 5 has not yet reached both sides of the reset member 6.

[0107] Step 3, see Fig.13 As shown, the second end 62 of the reset member 6 is slightly compressed along the first direction X, so that a certain distance is spaced between the second end 62 of the reset member 6 and the first connecting portion 41 , leaving space for the two second limiting columns 522 .

[0108] Since the length of the second limiting column 522 is relatively short, in this step, the compression of the restoring member 6 will not cause any obvious difficulty in operation.

[0109] Continue to move the second frame 5 along the third direction Z until the two second limiting posts 522 are respectively located on both sides of the first limiting post 411;

[0110] Step 4, see Fig.14 As shown, the second end 62 of the reset member 6 is released, so that the second limiting column 522 enters the second receiving groove 602. The reset member 6 naturally pushes the second frame 5 to move along the first direction X and toward the first connecting portion 41, so that the second connecting portion 51 slides into the guide groove 420.

[0111] Thus, the assembly of the housing 3 is completed. Then, the main body 71 of the connecting hook 7 is connected to the stump 92, the housing 3 is inserted into the mounting groove 930, the second connecting portion 51 is connected to the temple 93, and the hook 72 is connected to the first connecting portion 41.

[0112] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
