technical field

The present application relates to the technical field of head-mounted devices, and in particular, to a hinge and glasses.

Background technique

When the user wears the glasses, in order to prevent the glasses from loosening, the glasses need to generate a certain clamping force on the user's head. At present, the clamping force is generally provided by the deformation of the temple and the frame. If the deformation of the frame is large, the position of the lens relative to the human eye may change, which will have a certain impact on the user's visual image.

Utility model content

One aspect of the present application provides a hinge, comprising:

the first connecting piece has a first limiting surface;

the second connector;

The third connecting piece is rotatably connected with the first connecting piece, and the axis of the rotation of the third connecting piece relative to the first connecting piece extends along the first direction, and the third connecting piece also has a second limit when the third connecting piece rotates relative to the first connecting piece by a preset angle from the initial position, the second limiting surface abuts against the first limiting surface;

an elastic piece, elastically supported between the second connecting piece and the third connecting piece, and elastically deforming along a second direction perpendicular to the first direction;

A sliding block is fixedly connected to one of the second connecting piece and the third connecting piece, and the other one of the second connecting piece and the third connecting piece is provided with a For the chute, the plane perpendicular to the first direction is used as the projection plane, and the center line of the chute or the tangent of any point on the center line of the chute is not perpendicular to the second direction.

temples;

a pile head, one end of the pile head is connected with the mirror frame; and

In the above hinge, one of the first connecting piece and the second connecting piece is connected with the temple, and the other is connected with the other end of the pile head.

In the hinge disclosed in the present application, since the elastic member is elastically supported between the second connecting member and the third connecting member, under the action of the elastic member, the second connecting member and the first connecting member tend to move in opposite directions. Under the action of the elastic piece, the sliding block is in close contact with the chute at the first extreme position of the chute, so that when the second connecting piece or the first connecting piece is rotated, the second connecting piece can remain opposite to the third connecting piece by means of frictional force It is stationary and rotates integrally relative to the first connecting piece.

After the third connecting piece is rotated by a preset angle relative to the first connecting piece, the second limiting surface of the third connecting piece abuts against the first limiting surface of the first connecting piece, and the first connecting piece restricts the third connecting piece from continuing to face each other. its turning. Since the second connecting piece and the third connecting piece are slidably connected to the chute through the slider, the center line of the chute or the tangent at any point on the center line of the chute is not perpendicular to the second direction of elastic deformation of the elastic piece , at this time, continue to apply rotational force to overcome the elastic force generated by the elastic piece, so that the second connecting piece and the third connecting piece can move relatively along the chute until they move to the second limit position opposite to the first limit position. At the same time, during the relative movement of the second connecting member and the third connecting member, the elastic member is continuously compressed.

As shown in FIGS. 1 to 3 , the present embodiment provides a pair of glasses 100 , including a frame 10 , temples 20 , a head 30 and a hinge 40 . The frame 10 is connected by the head 30 and one end of the hinge 40 , and the other end of the hinge 40 is connected. One end is connected with the temple 20 , so that the temple 20 can be rotated relative to the frame 10 to retract or unfold the temple 20 . It should be noted that the pile head 30 refers to the part of the glasses 100 where the mirror frame 10 and the temple 20 are connected. The pile head 30 and the mirror frame 10 may be independent structures, or may be integrated, which is not limited here.

4 and 5 together, the hinge 40 includes a first connecting member 41 , a second connecting member 42 , a third connecting member 43 , an elastic member 44 and a slider 45 . The mirror frame 10 is connected with the first connecting piece 41 through the pile head 30 , and the temple 20 is connected with the second connecting piece 42 . The third connecting member 43 is rotatably connected to the first connecting member 41 and can abut against the first connecting member 41 when it is rotated relative to the first connecting member 41 by a preset angle from the initial position, and the third connecting member 43 is relatively connected to the first connecting member 41 The axis of rotation of the member 41 extends along the first direction X. The elastic member 44 is elastically supported between the second connecting member 42 and the third connecting member 43 and elastically deforms along the second direction Y perpendicular to the first direction X. As shown in FIG. The sliding block 45 is fixedly connected with the second connecting member 42 , and the third connecting member 43 is provided with a sliding groove 431 which is matched with the sliding block 45 . Taking a plane perpendicular to the first direction X as a projection plane, the tangent at any point on the center line of the chute 431 is not perpendicular to the second direction Y.

Since the elastic member 44 is elastically supported between the second connecting member 42 and the third connecting member 43 , under the action of the elastic member 44 , the second connecting member 42 and the first connecting member 41 tend to move in opposite directions. As shown in FIG. 6 , FIG. 6 is a cross-sectional view of the temple 20 , the pile head 30 and the hinge 40 on the right side when the temple 20 is folded. , and the cross-sectional direction is the positive direction of the X-axis. In the figure, the third connecting member 43 is in the initial position relative to the first connecting member 41, that is, when the temple 20 is in the retracted state as shown in FIG. 1, under the action of the elastic member 44, the second connecting member 42 moves clockwise The third connecting piece 43 tends to move counterclockwise, so that the slider 45 is in close contact with the chute 431 at the first extreme position of the chute 431 . When the temple 20 drives the second connecting member 42 and the third connecting member 43 to rotate relative to the first connecting member 41 from the retracted state as shown in FIG. 1 , the second connecting member 42 can rely on frictional force to connect with the third connecting member 43 It remains relatively stationary, and rotates integrally relative to the first connecting piece 41 .

After the third connecting member 43 is rotated relative to the first connecting member 41 by a preset angle, the temple 20 is in the unfolded state as shown in FIG. 2 . At this time, as shown in FIG. 7 , the third connecting member 43 and the first connecting member 41 Abutting, the first connecting piece 41 restricts the third connecting piece 43 from continuing to rotate. It should be noted that the sectional plane of FIG. 7 is perpendicular to the X axis, and is the symmetry plane of the two opposite surfaces of the temple 20, and the sectional direction is the positive direction of the X axis, but the temple 20 and the pile on the left opposite to FIG. 6 Cross-sectional view of head 30 and hinge 40 .

Since the second connecting piece 42 and the third connecting piece 43 are slidably connected to the chute 431 through the slider 45 , and the tangent at any point on the center line of the chute 431 does not correspond to the second direction Y of the elastic deformation of the elastic piece 44 Vertical, at this time, continue to apply rotational force to overcome the elastic force generated by the elastic member 44, so that the second connecting member 42 and the third connecting member 43 can move relatively along the chute 431 until the first limit position in FIG. 7 is reached , move to the second limit position opposite to the first limit position in FIG. 8 . At this time, the temples 20 are in the outwardly folded state as shown in FIG. 3 . At the same time, during the relative movement of the second connecting member 42 and the third connecting member 43 , that is, during the movement of the temple 20 from the position shown in FIG. 2 to the position shown in FIG. 3 , the elastic member 44 is continuously compressed. When the rotation force is canceled, the elastic member 44 is reset and drives the temples 20 to move in the adducting direction to generate a clamping force on the user's head, without the need to provide the clamping force through the deformation of the temples 20 or the frame 10 .

The specific structure of the hinge 40 is further described below:

In this embodiment, referring mainly to FIG. 5 and FIG. 6 , the third connecting member 43 is provided with a chute 431 , and the second connecting member 42 has a first receiving space 421 , and a part of the structure of the third connecting member 43 is located in the first connecting member 43 . Inside the accommodating space 421 , and the second connecting member 42 is provided with a mounting groove 422 penetrating with the chute 431 along the first direction X. One end of the slider 45 is fixed in the mounting groove 422 , and the other end is slidably mounted in the chute 431 . That is, the slider 45 is fixedly connected to the second connecting member 42 . Moreover, since the structure of the third connecting piece 43 with the sliding groove 431 is located in the first receiving space 421 of the second connecting piece 42 , and the structure of the second connecting piece 42 with the mounting groove 422 is located on the outside relative to the third connecting piece 43 , The size of the mounting groove 422 is smaller than that of the sliding groove 431 , and it is located outside to facilitate assembly and positioning.

In this embodiment, the second connecting member 42 is provided with installation grooves 422 on both sides of the first receiving space 421 along the first direction X. Correspondingly, the third connecting member 43 is also provided with two sliding grooves 431 . In this way, the relative movement of the second connecting member 42 and the third connecting member 43 is more stable.

It can be understood that, in other embodiments, the sliding block 45 can also be integrally formed with the second connecting member 42 . Alternatively, in other embodiments, the sliding groove 431 may also be provided on the second connecting member 42 , and at this time, the sliding block 45 is fixed on the third connecting member 43 .

In addition, the third connecting member 43 has a second accommodating space 432 and a first mounting hole 433 communicating with the second accommodating space 432. Part of the structure of the first connecting member 41 is located in the second accommodating space 432 and has a second mounting hole 433. hole 411. The hinge 40 further includes a rotating shaft 46 , the rotating shaft 46 passes through the first mounting hole 433 and the second mounting hole 411 , and the third connecting member 43 is rotatably connected to the first connecting member 41 through the rotating shaft 46 . Part of the structure of the first connecting member 41 is accommodated in the third connecting member 43 , which can reduce the volume and weight of the hinge 40 . Moreover, the partial structure of the third connecting piece 43 is accommodated in the second connecting piece 42 , that is, the partial structures of the second connecting piece 42 , the third connecting piece 43 and the first connecting piece 41 are set in sequence, which can further reduce the size of the hinge 40 . volume and weight.

Moreover, in this embodiment, the hinge 40 includes two rotating shafts 46, and there are also two first mounting holes 433 and two second mounting holes 411 respectively. The inside of the first connecting member 41 is a hollow structure, which can further reduce the size of the first connection. The space inside the first connecting piece 41 can be communicated with the first receiving space 421 and the second receiving space 432 , so that components such as circuit boards can be arranged inside the temple 20 .

5 and 6, a third receiving space 401 is formed between the second connecting member 42 and the third connecting member 43, the elastic member 44 is located in the third receiving space 401, and one end of the elastic member 44 is connected to the first connecting member 41 abuts, and the other end abuts with the third connecting piece 43 . In this embodiment, the elastic member 44 is an elastic piece, the second connecting member 42 has the third receiving space 401 , and the third receiving space 401 is communicated with the first receiving space 421 . The third connector 43 has a flange 434 extending therefrom. When the partial structure of the third connecting member 43 is accommodated in the first accommodation space 421, and the slider 45 is installed in the mounting groove 422 and the sliding groove 431, and the sliding block 45 is located at the first limit position of the sliding groove 431, the flange 434 The third accommodating space 401 is closed, and the elastic pieces located in the third accommodating space 401 are compressed, so that the elastic pieces have a certain amount of preload, so that the slider 45 is in close contact with the chute 431 at the first limit position of the chute 431 .

In this embodiment, the elastic sheet is selected to make the installation structure simple, and the elastic sheet is not easily shaken in a plane perpendicular to the second direction Y when it is deformed along the second direction Y. In other embodiments, the elastic member 44 can also be a torsion spring. In this case, a mounting shaft needs to be arranged along the first direction X in the third accommodation space 401 to sleeve the torsion spring, so that one end of the torsion spring is connected to the third The connecting piece 43 is in contact with the other end of the connecting piece 42 . Compared with using a torsion spring as the elastic member 44 , using an elastic sheet as the elastic member 44 does not require a mounting shaft, which can simplify the structure of the hinge 40 . Alternatively, in other embodiments, the elastic member 44 may also be a compression spring.

Referring mainly to FIG. 6 , the first connecting member 41 has a first limiting surface 412 , the third connecting member 43 has a second limiting surface 435 , and both the first limiting surface 412 and the second limiting surface 435 are aligned with the first direction X parallel. When the third connecting member 43 is in the initial position shown in FIG. 6 relative to the first connecting member 41 , that is, when the temple 20 is in the state shown in FIG. 1 , the first limiting surface 412 is perpendicular to the second limiting surface 435 .

Referring to FIG. 7 together, when the third connecting member 43 is rotated relative to the first connecting member 41 by a predetermined angle, that is, when the temple 20 is in the state shown in FIG. 2 , the first limiting surface 412 and the second limiting surface 435 Abut. That is, when the third connecting member 43 rotates 90° relative to the first connecting member 41 from the initial position, the first connecting member 41 restricts the further rotation of the third connecting member 43 . At this time, if further force is applied to the second connecting member 42 through the temple 20 , the elastic force of the elastic member 44 can be overcome, so that the second connecting member 42 moves relative to the third connecting member 43 in the chute 431 .

In this embodiment, the first limiting surface 412 and the second limiting surface 435 are respectively one surface of the first connecting member 41 and the third connecting member 43 , which has a simple structure and makes the total weight of the hinge 40 smaller. In other embodiments, the limiting structure may also be provided separately. For example, the first limiting surface may be the surface of the columnar structure that is fixedly connected to the main body of the first connector and protrudes from the surface, and the first limiting surface may be Flat, or curved. Similarly, the second limit surface can also be the surface of the structure that is fixedly connected to the main body of the third connector, which can be a plane or a curved surface, which is not limited here, as long as the first limit surface and the second limit When the surfaces are in contact with each other, the third connecting piece can no longer continue to rotate relative to the first connecting piece.

When assembling the hinge 40 , the part of the first connecting member 41 with the second mounting hole 411 may be placed in the second receiving space 432 first, so that the second mounting hole 411 communicates with the first mounting hole 433 . Then, the two rotating shafts 46 are respectively passed through the first installation hole 433 and the second installation hole 411 in sequence, so that the first connecting member 41 and the third connecting member 43 are rotatably connected. Then, the part of the third connector 43 with the chute 431 is put into the first accommodation space 421 so that the chute 431 communicates with the installation slot 422 , and the elastic piece is placed into the third accommodation space 401 . Then, the two sliding blocks 45 are respectively installed in the installation grooves 422 so that part of the structure of the sliding blocks 45 is located in the sliding grooves 431 , and at the same time, the flange 434 of the third connecting member 43 closes the third receiving space 401 .

After the hinge 40 is installed, the first connecting piece 41 is fixed on the pile head 30 . Specifically, the first connecting member 41 is provided with a first through hole 413 , the pile head 30 is provided with a first threaded hole 31 , and the first connecting member 41 is fixedly connected to the pile head 30 by screws. Similar to the connection method of the first connecting member 41 , the second connecting member 42 is provided with a second through hole 423 , the temple 20 is provided with a second threaded hole, and the second connecting member 42 is fixedly connected to the temple 20 by screws.

After the glasses 100 are assembled and the temples 20 are unfolded to the state shown in FIG. 2 , the end of the temple 20 is opposite to the end of the pile head 30 . For the convenience of subsequent description, referring to FIGS. 6 and 7 , the end face of the temple 20 toward the head 30 is referred to as the first end 22 , and the end of the head 30 toward the temple 20 is called the second end 32 , and the temple 20 is referred to as the second end 32 . The surface facing the outer side of the temple 20 in the two directions Y is called the outer surface 23 , and the intersection line between the outer surface 23 and the first end surface 22 is called the temple edge 24 .

In this embodiment, the chute 431 is an arc-shaped chute 431, and when the second connecting piece 42 moves relative to the third connecting piece 43 along the chute 431, that is, around the rotation centerline of the chute 431 (the width of the chute 431) The line where the center of the inner wall of the arc is located) rotates. Moreover, referring to the auxiliary line F in FIG. 7 , the temple edge 24 coincides with the rotation center line of the chute 431 , that is, the center of the rotation center line of the chute 431 is on the temple edge 24 . During the process that the temple 20 drives the slider 45 to move in the sliding groove 431 through the second connecting member 42, the position of the edge line 24 of the temple remains unchanged. That is to say, the distance L between the temple edge 24 and the second end surface 32 in FIG. 7 is equal to the distance L between the temple edge 24 and the second end surface 32 in FIG. 8 , and the temple edge 24 and the second end surface are equal. The distance between the temples 32 does not decrease during the outward folding of the temples 20 .

However, if the temple 20 is rotated to the position shown in FIG. 2 and still rotates around the axis of the rotating shaft 46, the temple edge 24 will move along the arc of the dotted circle in FIG. 7, and the temple edge 24 and the second end face The distance between 32 will decrease. That is to say, if the rotation center of the temple 20 is always the axis of the rotating shaft 46, when the temple 20 is folded outwards, the gap between the edge 24 of the temple and the second end face 32 of the pile head 30 will be reduced. When designing, these factors need to be considered, so that the distance between the temple edge 24 and the second end face 32 needs to be designed to be larger when the temple 20 is in the state shown in FIG. 2, which will affect the appearance, and the larger gap is not conducive to The dustproof and waterproof performance of the inner structure of the temple 20 is improved.

In this embodiment, when the temple 20 is rotated to the state shown in FIG. 2 and FIG. 3 , the distance L between the side line 24 of the temple and the second end surface 32 is between 0.5 mm and 0.8 mm, so as to improve the overall quality of the glasses 100 . Compact and aesthetically pleasing.

In other embodiments, the temple edge 24 may not overlap with the rotation center line of the chute 431, but the distance between the temple edge 24 and the rotation center line of the chute 431 is smaller than the distance between the temple edge 24 and the axis of the rotating shaft 46. distance. In this way, relative to the rotation around the axis of the rotating shaft 46, the rotation around the rotation center line of the chute 431 can reduce the turning radius of the temple edge 24, thereby reducing the reserved gap between the temple edge 24 and the second end surface 32 . It can be understood that the center line of the arc-shaped chute 431 is an arc, and the center of the circle remains unchanged, so that the rotation center line of the chute 431 remains unchanged. However, in other embodiments, the center line of the chute 431 may also be a part of an elliptical arc or other types of curves.

In addition, if the gap between the temple edge 24' and the second end face is not considered, in other embodiments, as shown in FIG. 9, the sliding groove 431' can also be a linear groove. At this time, a plane perpendicular to the first direction X is used as a projection plane, and the center line of the chute 431 ′ is a line segment, which is not perpendicular to the second direction Y. When the second connecting piece moves relative to the third connecting piece along the sliding groove 431 ′ through the slider 45 ′, the temple edge 24 ′ translates in a direction parallel to the center line of the sliding groove 431 ′.

It should be noted that, in the above embodiment, the frame 10 is connected with the first connecting member 41 , the temple 20 is connected with the second connecting member 42 , and the hinge 40 receives external force through the second connecting member 42 . In other embodiments, the temple 20 can also be connected with the first connecting member 41 , and the frame 10 can be connected with the second connecting member 42 . At this time, when the temple 20 is in the initial position as shown in FIG. 1 , the temple 20 exerts a force on the first connecting piece 41 , and the third connecting piece 43 and the second connecting piece 42 are kept under the action of the elastic piece 44 . Relatively static, the temple 20 drives the first connecting member 41 to rotate relative to the third connecting member 43 and the second connecting member 42 . When the temple 20 is rotated to the unfolded state as shown in FIG. 2 , that is, when the first connecting member 41 is rotated relative to the third connecting member 43 and the second connecting member 42 by a preset angle, the first limit of the first connecting member 41 The surface 412 is in contact with the second limiting surface 435 of the third connecting piece 43 . At this time, if the temple 20 continues to be rotated, because the third connecting piece 43 and the second connecting piece 42 are connected by the slider 45 and the sliding groove 431 , the temple 20 will drive the third connecting piece 43 through the first connecting piece 41 . move together relative to the second link 42 . During the movement, the elastic member 44 between the third connecting member 43 and the second connecting member 42 is further compressed, so as to provide a restoring force when the external force applied to the temple 20 is cancelled, so that the temple 20 generates a clamping force.

It is worth mentioning that the glasses in this solution can be different types of glasses such as myopia glasses, sunglasses, augmented reality (AR) glasses or virtual reality (VR) glasses, especially for smart glasses such as AR glasses or VR glasses. Glasses generally have display and audio functions. The size of the frame 10 and the temple 20 are relatively large and are not easily deformed. The hinge 40 can not only realize the rotation function of the temple 20, but also provide a clamping force for the temple 20. The temples 20 and the frame 10 themselves will not be deformed. Moreover, compared with the hinge using the cam and spring structure, the hinge 40 of the present solution has a smaller structural size, and the overall weight can also be reduced, which can improve the comfort of the wearer. At the same time, the rotating shaft 46 of the smart glasses generally needs to pass the FPC line, and during the rotation of the temple 20, the FPC length on the outer circumference of the rotating shaft 46 will change. The length of the FPC is the FPC redundant length, and the larger the size of the rotating shaft 46 of the hinge 40 using the cam and the spring, a larger FPC redundant length needs to be reserved.

Of course, the hinge 40 in this solution can also be used for other structures that need to achieve relative rotation in addition to the glasses 100 , which is not limited here.
