Description

Hinge assembly and frame TECHNICAL FIELD

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

[0002] At present, in the structural design of the frame, in addition to being able to be folded inwardly relative to the post head for storage, the temple also has bending and recovery in other directions, so as to ensure that the temple can withstand loads in abnormal directions, maintain the integrity of the frame in unexpected accidental bending, and prolong the service life. For example, the temple can be bent upward, downward or inward relative to the post head by elongation and recovery of the hinge assembly.

[0003] In the existing hinge assembly between the temple and the post head, the spring is limited inside a semi-open shell and is penetrated by a sliding rod. During the bending of the temple relative to the post head, the sliding rod slides relative to the shell and the spring. During the sliding of the sliding rod, the spring is compressed. The existing problems of this kind of hinge assembly are as follows: 1. The machining difficulty is great. The hollow inside of the semi-open shell is provided with a hole at one end and a hole at the side. The hole at one end is for the sliding rod to penetrate, and the hole at the side is for the spring to be put in and taken out. The other faces are not provided with a hole. The machining process of this semi-open shell is complex and has high cost. 2. The assembly is complex. The spring needs to be penetrated by the sliding rod first, and then put into the shell from the hole at the side in the compressed state. The assembly of the sliding rod is difficult, so the length of the sliding rod is limited.

[0051] In order to illustrate the technical scheme described in the present application, the following will be described in detail in combination with specific drawings and examples.

[0052] Please refer to FIG. 1 and FIG. 2, the present application embodiment first provides a frame 200, which includes a frame 91, a post head 92, a hinge assembly 100 and a temple 93 connected in turn. Among them, please refer to FIG. 2 to FIG. 4, by means of the hinge assembly 100, the temple 93 can be relatively bent in at least two directions relative to the post head 92 and the frame 91.

[0053] For the convenience of description, three directions, up-down direction, left-right direction and front-rear direction are defined below, referring to FIG. 1, FIG. 3 and FIG. 4, which are based on the case that the user wears the frame 200 (or glasses containing the frame 200) normally and keeps looking straight.

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

[0055] Next, referring to FIG. 5 to FIG. 8, the hinge assembly 100 of the present application will be described in detail.

[0056] As shown in FIG. 6, FIG. 7 and FIG. 8, the hinge assembly 100 comprises a housing 3 and a reset member 6, the reset member 6 is arranged in the housing 3, one end of the housing 3 is used for connecting with the post head 92, and the other end is used for connecting with the temple 93, please refer to FIG. 2 and FIG. 5. When the temple 93 is bent relative to the post head 92, the length of the housing 3 changes, thereby driving the length of the reset member 6 to change.

[0057] Specifically, referring to FIG. 6 and FIG. 7, the housing 3 comprises a first frame 4 and a second frame 5 which can slide relative to each other along the first direction X. The first frame 4 comprises a first connecting part 41 used for connecting with the post head 92, a first limiting part 42 facing the temple 93, and a plurality of first rods 43; both ends of each first rod 43 are connected with the first connecting part 41 and the first limiting part 42 respectively, 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 surrounding the plurality of first rods 43, it can be understood that the surrounding here does not mean closed surrounding.

[0058] Referring to FIG. 6 and FIG. 7, the second frame 5 comprises a second connecting part 51 used for connecting with the temple 93, a second limiting part 52 facing the post head 92, and a plurality of second rods 53, both ends of each second rod 53 are connected with the second connecting part 51 and the second limiting part 52 respectively, 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 surrounding the plurality of second rods 53, it can be understood that the surrounding here does not mean closed surrounding.

[0059] Please refer to FIG. 7 and FIG. 9, the second limiting part 52 includes two limiting ends 521 spaced apart in the second direction Y, and a sliding groove 520 is formed between the limiting ends 521 and penetrates through in the second direction Y, that is, the sliding groove 520 is communicated with the second space 50 and the end face of the second limiting part 52 away from the first connecting part 41 in the second direction Y. In the embodiment, the width of the sliding groove 520 is configured to allow the first connecting part 41 of the first frame 4 to slide in the first direction X and the third direction Z in the sliding groove 520. Here, the width refers to the size in the second direction Y. The second direction Y and the third direction Z are 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 FIG. 5 and FIG. 6, the reset member 6 is arranged in the first space 40 and the second space 50, and the first end 61 is connected to the first limiting part 42 and the second end 62 is connected to the second limiting part 52. Here, the first end 61 and the second end 62 of the reset member 6 are limited by the first limiting part 42 and the second limiting part 52 respectively, and the first end 61 cannot pass the first limiting part 42 in a direction and the second end 62 cannot pass the second limiting part 52 in the first direction X.

[0061] Wherein, the first frame 4 slides in the sliding groove 520 in the first direction X, that is, the first frame 4 and the second frame 5 relatively slide in the first direction X, which can make the plurality of first rods 43 respectively located on the opposite sides of the second frame 5 and the plurality of second rods 53 respectively located on the two sides of the first frame 4, that is, the first space 40 and the second space 50 cross each other, please refer to FIG. 8; since the relative sliding of the first frame 4 and the second frame 5 in the first direction X is limited by the reset member 6, when the first frame 4 slides in the sliding groove 520 in the third direction Z, the first frame 4 and the second frame 5 can be separated and combined without avoiding the reset member 6.

[0062] When the temple 93 is bent relative to the post head 92, the second frame 5 slides relative to the first frame 4 in the first direction X, the second limiting part 52 approaches the first limiting part 42 in 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, with the frame 91 and the post head 92 as the reference datum. When the force bending the temple 93 is removed, the second frame 5 reversely slides relative to the first frame 4 in the first direction X under the action of the restoring force of the reset member 6, the second limiting part 52 moves away from the first limiting part 42 in the first direction X, and the reset member 6 is elongated until the temple 93 returns to be flush with the post head 92.

[0063] It should be noted that the first direction X described above can be parallel to the front-rear direction, or, according to the position arrangement between the temple 93 and the post head 92, the first direction X can have a certain angle with the front-rear direction. But generally, the first direction X is the compressed direction and the recovery direction of the reset member 6 when the temple 93 is bent relative to the post head 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] And when the first direction X is parallel to the front-rear direction, the second direction Y can be parallel to the left-right direction, or can be inclined to the left-right direction.

[0066] The hinge assembly 100 provided by the embodiments of the present application is composed of the first frame 4 and the second frame 5 which can slide relative to each other along the first direction X and the 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 more convenient, 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 FIG. 7 and FIG. 9, in an embodiment, the first frame 4 includes two first rods 43, and the two first rods 43 are arranged in the third direction Z; please refer to FIG. 7 and FIG. 10, the second frame 5 includes two second rods 53, and the two second rods 53 are arranged in the second direction Y. In this way, the first frame 4 and the second frame 5 are generally flat, which can further simplify the processing and manufacturing difficulty of the first frame 4 and the second frame 5.

[0068] The circumferential side of the reset member 6 is alternately arranged by the two first rods 43 and the two second rods 53, please refer to FIG. 6 and FIG. 8.

[0069] In other optional embodiments, on the basis of not affecting the relative sliding between the first frame 4 and the second frame 5 along the first direction X and the third direction Z, the first frame 4 can include more than two first rods 43, and / or the second frame 5 can include more than two second rods 53. Generally, the number of the first rods 43 and the second rods 53 should not be too much, so as to ensure the convenient processing of the first frame 4 and the second frame 5.

[0070] Please refer to FIG. 7, FIG. 8 and FIG. 9, the first connecting part 41 is provided with a first limiting column 411, the first limiting column 411 is located in the first space 40 and extends from the inner end face of the first connecting part 41 to the first limiting part 42; please refer to FIG. 7, the second end 62 of the reset member 6 is provided with a second accommodating groove 602 capable of accommodating the first limiting column 411.

[0071] The purpose of such arrangement is that, by inserting the first limiting post 411 into the reset member 6, the movement of the reset member 6 in other directions can be limited, so that the reset member 6 is compressed along the first direction X, and the bending of the reset member 6 during the compression along the first direction X is avoided, and the situation that the reset member 6 cannot be recovered smoothly is avoided.

[0072] The length of the first limiting post 411 should be less than the length of the first space 40, and hereinafter, the length refers to the dimension along the first direction X. Alternatively, the length of the first limiting post 411 should be less than half of the length of the first space 40, or there is other size relationship between the length of the first limiting post 411 and the length of the first space 40. This can be beneficial for the installation of the reset member 6 in the first space 40 and the cooperation between the reset member 6 and the first limiting post 411.

[0073] Please refer to FIG. 7 and FIG. 8, it is shown that the first limiting post 411 extends along the first direction X, and has two side surfaces in the second direction Y, which can be used as guiding surfaces 4111 for the sliding of the two limiting ends 521. 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 guiding surfaces 4111 of the first limiting post 411, so that the sliding direction of the second frame 5 can be further maintained.

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

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

[0076] In another embodiment, the reset member 6 is a columnar body with elasticity, and the second accommodating groove 602 is a through hole or a blind hole opened on the columnar body.

[0077] Please refer to FIG. 7 and FIG. 10, the second limiting part 52 further includes at least one second limiting post 522, which is connected to the limiting end 521, and is optionally connected to the inner side of the limiting end 521, i.e. the side close to each other, and extends towards the second connecting part 51 and is located in the second space 50. That is, the second limiting post 522 is located on at least one side of the first limiting post 411 along the second direction Y, and the second limiting post 522 is also located in the second accommodating groove 602 of the reset member 6.

[0078] In other words, the second limiting post 522 and the limiting end 521 form a hook-shaped structure, the second limiting post 522 is inserted into the reset member 6 to compress the reset member 6 in a manner of hooking the reset member 6, and the compression direction of the reset member 6 is further ensured.

[0079] In an optional embodiment, the two limiting ends 521 are connected with the second limiting posts 522 on the sides close to each other.

[0080] The length of the second limiting post 522 is less than the length of the first limiting post 411, so as to be inserted into the reset member 6 and to slide along the guide surface 4111 of the first limiting post 411.

[0081] In other optional embodiments, only the first limiting post 411 or only the second limiting post 522 can be arranged on the shell 3.

[0082] As shown in FIG. 7 and FIG. 9, in an embodiment, the side of the first limiting portion 42 away from the first space 40 is provided with a guide groove 420 recessed in the first direction X, and 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 an embodiment, as shown in FIG. 9, since the first limiting portion 42 is generally flat and perpendicular to the second frame 5, the guide groove 420 penetrates 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 post 411 has been blocked between the two limiting ends 521 in 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] As shown in FIG. 7 and FIG. 9, in an embodiment, the side of the first limiting portion 42 facing the first space 40 is provided with a third limiting post 421; as shown in FIG. 7, the first end 61 of the reset member 6 is provided with a first accommodating groove 601 capable of accommodating the third limiting post 421. The third limiting post 421 can limit the first end 61 of the reset member 6, avoiding the bending of the first end 61 of the reset member 6 in other directions.

[0086] Correspondingly, the first accommodating groove 601 can be a blind hole opened from the end face of the first end 61, or a through hole penetrating the first end 61 and the second end 62.

[0087] When the first accommodating groove 601 is a through hole penetrating the first end 61 and the second end 62 thereof, the second accommodating groove 602 is completely coincident with the first accommodating groove 601, that is, at this time, the through hole penetrating the first end 61 and the second end 62 of the reset 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 relatively small, for example, less than the length of the first limiting column 411. In this way, the difficulty of installing the reset member 6 in the first space 40 can be minimized, and the machining and manufacturing of the first frame 4 are also facilitated.

[0089] In an optional embodiment, as shown in FIG. 9, 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 on the basis of ensuring that the length of the guide groove 420 is sufficient, so as to reduce the overall length of the first frame 4 and the shell 3, and further reduce the space occupied between the frame 200 and the post head 92 of the hinge assembly 100.

[0090] Please refer to FIGS. 7, 8 and 9, in an embodiment, the first connecting portion 41 of the first frame 4 is provided with a first connecting hole 410; please refer to FIGS. 6 and 7, the hinge assembly 100 further includes a connecting hook portion 7, which includes a main body 71 and a hook 72, wherein, please refer to FIGS. 5, 6 and 7, the main body 71 is used to connect with the post head 92, and the hook 72 is used to cooperate with the first connecting hole 410.

[0091] Through the size and / or shape of the hook 72 and the first connecting hole 410, for example, the inner side surface of the hook 72 is designed as a curved surface, and the inner side surface of the first connecting hole 410 is designed as a curved surface, etc., the cooperation between the hook 72 and the connecting hole can be relatively movable in any direction except that the hook 72 cannot be separated from the first connecting hole 410 in the first direction X. 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 left-up, right-down, etc. In other words, the first frame 4 can be equivalent to the hook 72 to realize 360-degree bending. This further improves the bending flexibility of the hinge assembly 100 and improves the bearing capacity of the frame 200 to more accidental direction loads.

[0092] Since the hook 72 and the first frame 4 can realize 360-degree relative bending, the connection between the hook 72 and the main body 71 can be a fixed connection or a rotary connection about at least one rotary axis.

[0093] Likewise, the main body 71 of the connecting hook 7 can be fixedly connected with the post head 92, or rotatably connected with the post head 92 about at least one rotational axis of rotation.

[0094] Since the first frame 4 is a substantially planar structure along the third direction Z, the first connecting hole 410 can be a through hole along the second direction Y, as shown in FIG. 7 and FIG. 9. This facilitates the manufacture of the first connecting hole 410.

[0095] As shown in FIG. 5, FIG. 6 and FIG. 7, in an optional embodiment, the main body 71 is provided with a third connecting hole 710, and the first pin shaft 94 passes through the post head 92 and the third connecting hole 710 to connect the post head 92 with the connecting hook 7. At this time, the third connecting hole 710 can be a through hole along the third direction Z, which also facilitates the manufacture of the connecting hook 7.

[0096] The main body 71 can be fixedly connected with the post head 92, so that the main body 71 cannot rotate about the first pin shaft 94. Alternatively, the main body 71 can rotate about the first pin shaft 94, which can further provide flexibility of the hinge assembly 100.

[0097] In other embodiments, the first frame 4 can be rotatably connected with the post head 92 in other ways, for example, the first connecting portion 41 of the first frame 4 can rotate about one axis of rotation, or the first connecting portion 41 can rotate about multiple axes of rotation.

[0098] As shown in FIG. 5, in order to reduce the distance between the temple 93 and the post head 92, i.e., to hide the hinge assembly 100 as much as possible, in an embodiment, the side of the temple 93 facing the post head 92 is provided with a mounting groove 930, and at least part 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 post head 92, the hinge assembly 100 can be mostly or completely hidden in the first direction X, as shown in FIG. 1, FIG. 3 and FIG. 4.

[0099] As shown in FIG. 7, FIG. 8 and FIG. 10, the second connecting portion 51 is provided with a second connecting hole 510, and the second connecting hole 510 is connected with the temple 93 through a second pin shaft 95. Since the second frame 5 is at least partially accommodated in the mounting groove 930, the second frame 5 can be fixedly arranged in the mounting groove 930, i.e., the second frame 5 cannot rotate about the second pin shaft 95 relative to the temple 93. At this time, the size of the second frame 5 can be substantially equal to, as much as possible equal 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 piece or a plastic piece, according to the design requirement of the bonding strength. The second frame 5 can be a metal piece or a plastic piece, according to the design requirement of the bonding strength.

[0101] The first frame 4 can be an integrally formed piece, such as a metal integrally formed stamping piece, or a plastic integrally formed injection molding piece, etc. The second frame 5 can be an integrally formed piece, such as a metal integrally formed stamping piece, or a plastic integrally formed injection molding piece, etc.

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

[0103] Next, please refer to FIGS. 11-14, the hinge assembly 100 provided by the embodiments of the present application is assembled as follows:

[0104] Step one, please refer to FIG. 11, the reset member 6 is installed on the first frame 4 after being slightly compressed, the first limiting post 411 enters the second accommodating groove 602, and the third limiting post 421 enters the first accommodating groove 601; the reset member 6 is released, and the reset member 6 is elongated and naturally abuts against the side where the first connecting portion 41 and the second limiting portion 52 are close to each other.

[0105] 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 arrangement in the first space 40 do not bring obvious difficulty in operation.

[0106] Step two, please refer to FIG. 12, the second frame 5 is moved along the third direction Z, so that the two limiting ends 521 are respectively located on the two sides of the first connecting portion 41 of the first frame 4; at this time, the second rod 53 of the second frame 5 has not reached the two sides of the reset member 6.

[0107] Step three, please refer to FIG. 13, the second end 62 of the reset member 6 is slightly compressed along the first direction X, so that the second end 62 of the reset member 6 is spaced apart from the first connecting portion 41 by a certain distance, leaving space for the two second limiting posts 522.

[0108] In this step, the compression of the reset member 6 does not bring obvious difficulty in operation, because the length of the second limiting post 522 is small.

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

[0110] Step four, please refer to FIG. 14, the second end 62 of the reset member 6 is released, so that the second limiting column 522 enters the second containing groove 602. The reset member 6 naturally pushes the second frame 5 to move along the first direction X and towards the first connecting part 41, so that the second connecting part 51 slides into the guide groove 420.

[0111] In this way, the assembly of the shell 3 is completed. Then, the main body 71 of the connecting hook part 7 is connected with the pile head 92, the shell 3 is inserted into the installation groove 930, the second connecting part 51 is connected with the temple leg 93, and the bent hook 72 is connected with the first connecting part 41.

[0112] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
