TECHNICAL FIELD

[0001] The utility model relates to glasses technical field, especially a kind of frame and intelligent glasses. BACKGROUND

[0002] The glasses on market are mainly composed of lens and frame, and the frame is mainly composed of leg and frame loaded lens. In the related art, the frame and the leg are connected by rotating shaft, and then the rotating shaft is respectively sleeved with the first damping member and the second damping member, the first damping member and the second damping member are respectively connected with the frame and the leg, the lower end surface of the first damping member and the upper end surface of the second damping member are abutted to provide damping force when the leg rotates relative to the frame. However, due to the small size of glasses, the volume of the first damping member and the second damping member is small, which leads to small contact area between the first damping member and the second damping member, so that the damping force generated between the first damping member and the second damping member is small, which is difficult to meet the use requirement.

[0007] In the frame of the application, the clamping portion of the rotating piece is clamped in the clamping groove of the second support, the rotating shaft is fixedly connected with the first support and rotatably connected with the second support, thus, when the first support rotates relative to the second support under the driving of external force, the first support can drive the rotating shaft to rotate relative to the second support, since the clamping portion of the rotating piece is clamped in the clamping groove of the second support, the rotating shaft will rotate relative to the damping portion, and the damping force that hinders the first support from continuously rotating relative to the second support is generated between the rotating shaft and the damping portion; when the first support rotates to a preset angle relative to the second support, the external force applied on the first support is removed, at this time, since the damping portion is in interference fit with the rotating shaft, the damping force between the rotating piece and the rotating shaft hinders the first support from rotating relative to the second support, so that the first support and the second support can be stably kept at the preset angle. It can be understood that, since the through hole is formed in the damping portion and the rotating shaft is arranged in the through hole, the rotating shaft can fully contact with the damping portion in the circumferential surface, under the premise that the size of the rotating shaft is constant, the contact area between the rotating shaft and the damping portion can be larger, so that the damping force between the rotating piece and the rotating shaft can be larger, so that the first support and the second support can be stably kept at the preset position, and thus, the frame of the application can more easily meet the use requirements of the user and improve the use experience of the user.

[0031] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, left, right, front, and back, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] The following is for reference. Figures 1 to 5 A glasses frame according to the first aspect of this utility model will be described in detail.

[0036] refer to Figures 1 to 4 According to an embodiment of the present invention, a glasses frame includes a first support 100, a second support 200, a rotating shaft 300, and a rotating plate 400; the second support 200 is provided with a slot 201; the rotating shaft 300 is fixedly connected to the first support 100 and rotatably connected to the second support 200; the rotating plate 400 includes a damping part 410 and a locking part 420 connected to each other, the damping part 410 has a through hole 411, the rotating shaft 300 passes through the through hole 411 and is interference-fitted with the damping part 410, and the locking part 420 passes through the slot 201.

[0037] In the eyeglass frame of this application, the locking portion 420 of the rotating plate 400 is engaged in the slot 201 of the second support 200, while the rotating shaft 300 is fixedly connected to the first support 100 and rotatably connected to the second support 200. Therefore, when the first support 100 rotates relative to the second support 200 under external force, the first support 100 can drive the rotating shaft 300 to rotate relative to the second support 200. Since the locking portion 420 of the rotating plate 400 is engaged in the slot 201 of the second support 200, the rotating shaft 300 will rotate relative to the damping portion 410. When the first support 100 rotates relative to the second support 200, a damping force is generated between the rotating shaft 300 and the damping part 410 to prevent the first support 100 from continuing to rotate relative to the second support 200. When the first support 100 rotates relative to the second support 200 to a preset angle, the external force applied to the first support 100 is removed. At this time, due to the interference fit between the damping part 410 and the rotating shaft 300, the damping force between the rotating plate 400 and the rotating shaft 300 will prevent the first support 100 from rotating relative to the second support 200, so that the first support 100 and the second support 200 can be stably maintained at the preset angle. It is understandable that, since the damping part 410 has a through hole 411 and the rotating shaft 300 passes through the through hole 411, the rotating shaft 300 can fully contact the damping part 410 on its circumferential surface. Under the premise that the size of the rotating shaft 300 is fixed, the contact area between the rotating shaft 300 and the damping part 410 can be set to be larger, thereby generating a larger damping force between the rotating plate 400 and the rotating shaft 300, so that the first bracket 100 and the second bracket 200 can be stably maintained in the preset position. As a result, the frame of this application is more likely to meet the user's usage needs and improve the user's experience.

[0038] refer to Figure 2 and Figure 3 In some embodiments of this utility model, the damping part 410 is provided with a first end 412 and a second end 413 along the circumference of the rotation axis 300. Under the action of external force, the first end 412 and the second end 413 can move closer or further away from each other to adjust the diameter of the through hole 411. Understandably, the user can increase the diameter of the through hole 411 by driving the first end 412 away from the second end 413, thereby reducing the pressure between the damping part 410 and the rotating shaft 300, and thus reducing the damping force between the rotating shaft 300 and the damping part 410. The user can also decrease the diameter of the through hole 411 by driving the first end 412 closer to the second end 413, thereby increasing the pressure between the damping part 410 and the rotating shaft 300, and thus increasing the damping force between the rotating shaft 300 and the damping part 410. Furthermore, by adjusting the relative distance between the first end 412 and the second end 413, the user can adjust the magnitude of the damping force between the rotating shaft 300 and the rotating plate 400, making the adjustment process of the damping force between the rotating shaft 300 and the rotating plate 400 simpler and more convenient.

[0039] like Figure 2 and Figure 3 As shown, in one embodiment, the damping part 410 and the snap-fit ​​part 420 are integrally formed, and the snap-fit ​​part 420 is connected to the first end 412. It can be understood that since the damping part 410 and the snap-fit ​​part 420 are integrally formed, and the snap-fit ​​part 420 is connected to the first end 412, the user only needs to surround the rotating piece 400 around the rotating shaft 300 and bend part of the rotating piece 400 to snap it into the slot 201 to achieve the setting of the rotating piece 400. The manufacturing of the rotating piece 400 is relatively simple and easy to implement.

[0040] refer to Figures 2 to 4 As shown, in some embodiments of this utility model, the first bracket 100 includes a first frame 110 and a first fixed seat 120, which are detachably connected. The second bracket 200 includes a second frame 210 and a second fixed seat 220, which are detachably connected. The second fixed seat 220 has a slot 201. The rotating shaft 300 is fixedly connected to the first fixed seat 120 and rotatably connected to the second fixed seat 220. It can be understood that by detachably connecting the first fixed seat 120 to the first frame 110, when the first fixed seat 120 or the first frame 110 is damaged, only the first fixed seat 120 or the first frame 110 needs to be replaced. Similarly, by detachably connecting the second fixed seat 220 to the second frame 210, when the second fixed seat 220 or the second frame 210 is damaged, only the second fixed seat 220 or the second frame 210 needs to be replaced, thereby reducing maintenance costs.

[0041] The following is for reference Figures 1 to 5 A smart glasses according to a second aspect embodiment of the present invention will be described in detail.

[0042] A smart glasses according to a second aspect of the present invention includes a frame according to a first aspect of the present invention.

[0043] refer to Figure 3 and Figure 5 In some embodiments of this utility model, the smart glasses further include a power-connecting structure 500. A receiving cavity 600 is defined between the position where the first bracket 100 is connected to the rotation shaft 300 and the position where the second bracket 200 is connected to the rotation shaft 300. One end of the power-connecting structure 500 is connected to an electrical structure within the first bracket 100, and the other end of the power-connecting structure 500 extends through the receiving cavity 600 into the second bracket 200 and connects to an electrical structure within the second bracket 200. It is understood that by placing the power-connecting structure 500 within the receiving cavity 600 formed by the first bracket 100 and the second bracket 200, the possibility of the power-connecting structure 500 being exposed can be reduced, thereby protecting the power-connecting structure 500 and further improving the aesthetics of the smart glasses.

[0044] Specifically, the power connection structure 500 is an FPC.

[0045] like Figure 3 and Figure 5 As shown, in some embodiments, both the rotating shaft 300 and the rotating plate 400 are housed within the receiving cavity 600, and the electrical connection structure 500 passes through the inner wall between the rotating plate 400 and the receiving cavity 600. It is understood that by placing the rotating shaft 300 and the rotating plate 400 within the receiving cavity 600, the contact between the rotating plate 400 and the rotating shaft 300 and the outside environment can be reduced, thereby protecting the rotating plate 400 and the rotating shaft 300.

[0046] In a further embodiment of this utility model, the portion of the power-connecting structure 500 located within the receiving cavity 600 is arc-shaped and arranged around the rotating plate 400. It is understood that this arrangement makes the relative distances between the various portions of the power-connecting structure 500 within the receiving cavity 600 and the rotating plate 400 more consistent, thereby reducing the probability of friction between the rotating plate 400 and the power-connecting structure 500 during the rotation of the first support 100 relative to the second support 200, and thus extending the service life of the power-connecting structure 500.

[0047] like Figure 2 , Figure 3 and Figure 5In some embodiments, the first bracket 100 includes a first fixing seat 120, which includes a first connecting portion 121 and a first limiting portion 122 connected together. The second bracket 200 includes a second fixing seat 220, which includes a second connecting portion 221 and a second limiting portion 222 connected together. The rotating shaft 300 is fixedly connected to the first connecting portion 121, and the other end of the rotating shaft 300 is rotatably connected to the second connecting portion 221. The first limiting portion 122 and the second limiting portion 222 are circumferentially distributed around the rotating shaft 300. The first connecting portion 121, the first limiting portion 122, the second connecting portion 221, and the second limiting portion 222 together define a receiving cavity 600.

[0048] It is understandable that by distributing the first limiting part 122 and the second limiting part 222 circumferentially around the rotation axis 300, the first limiting part 122 and the second limiting part 222 can be distributed on opposite sides of the power-connecting structure 500 in the thickness direction. Thus, the first limiting part 122 and the second limiting part 222 can protect the power-connecting structure 500 from the thickness direction. By providing the first connecting part 121 and the second connecting part 221 at both ends of the rotation axis 300, the first connecting part 121 and the second connecting part 221 can be distributed on opposite sides of the power-connecting structure 500 in the thickness direction. The power-connecting structure 500 is located on opposite sides in its width direction, so that the first connecting part 121 and the second connecting part 221 can protect the power-connecting structure 500 from the width direction of the power-connecting structure 500. Since the first limiting part 122, the second limiting part 222, the first connecting part 121 and the second connecting part 221 are not distributed in the extension direction of the power-connecting structure 500, the power-connecting structure 500 can be protected by the first fixing seat 120 and the second fixing seat 220 while reducing the interference experienced by the power-connecting structure 500 in its own extension direction.

[0049] In a specific embodiment of this utility model, the first connecting part 121 is provided with a first mounting hole 121a, and the second connecting part 221 is provided with a second mounting hole 221a. The first mounting hole 121a is an oblong hole, and the second mounting hole 221a is a circular hole. One end of the rotating shaft 300 is rotatably inserted into the second mounting hole 221a, and the other end of the rotating shaft 300 is inserted into the first mounting hole 121a and is interference-fitted with the first mounting hole 121a. Since the first mounting hole 121a is an oblong hole, it can restrict the relative rotation of the rotating shaft 300 relative to the first connecting part 121. Part of the structure of the first limiting part 122 is plugged and plugged into the first frame 110, and part of the structure of the second limiting part 222 is plugged and plugged into the second frame 210.

[0050] In a further embodiment of the present invention, the slot 201 extends along the axial direction of the rotation shaft 300, and along the axial direction of the rotation shaft 300, the end of the second limiting part 222 opposite to the second connecting part 221 is formed with an installation port 222a, which is connected to the slot 201.

[0051] Understandably, the mounting port 222a allows the snap-fit ​​part 420 to be installed in the slot 201 along the axis of the rotating shaft 300 via the mounting port 222a, or to be disassembled from the slot 201, making it easier to assemble and disassemble the rotating piece 400 and the second fixed seat 220.

[0052] refer to Figure 2 , Figure 4 and Figure 5 In some embodiments of this utility model, a first limiting structure is provided on the first bracket 100 and a second limiting structure is provided on the second bracket 200. When the first bracket 100 and the second bracket 200 rotate relative to each other to a preset angle, the first limiting structure and the second limiting structure abut against each other to restrict the rotation of the first bracket 100 and the second bracket 200. Understandably, when the user overcomes the damping force between the rotating plate 400 and the rotating shaft 300 and drives the first bracket 100 to rotate relative to the second bracket 200 to a preset angle, the first limiting structure on the first bracket 100 abuts against the second limiting structure on the second bracket 200, thereby preventing the first bracket 100 from rotating relative to the second bracket 200 and limiting the rotation angle between the first bracket 100 and the second bracket 200. When the first bracket 100 rotates relative to the second bracket 200, the power connection structure 500 itself will bend. By limiting the rotation angle of the first bracket 100 relative to the second bracket 200, the bending angle of the power connection structure 500 itself can be limited, thereby reducing the probability of damage to the power connection structure 500 due to excessive bending angle.

[0053] like Figure 2 , Figure 4 and Figure 5As shown, in some embodiments, one of the first limiting structure and the second limiting structure is an abutment protrusion 202, and the other is an arc groove 102. The abutment protrusion 202 is slidably disposed in the arc groove 102. When the first bracket 100 and the second bracket 200 rotate relative to each other to a preset angle, the two side walls of the arc groove 102 in the circumferential direction of the rotation axis 300 can abut against the abutment protrusion 202 to limit the rotation of the first bracket 100 and the second bracket 200. It is understandable that when the first support 100 rotates forward relative to the second support 200 to a preset angle, the abutting protrusion 202 of the second support 200 slides forward in the arc groove 102 until it abuts against one side of the arc groove 102 in the circumferential direction of the rotation axis 300; when the first support 100 rotates backward relative to the second support 200 to a preset angle, the abutting protrusion 202 of the second support 200 slides backward in the arc groove 102 until it abuts against the other side of the arc groove 102 in the circumferential direction of the rotation axis 300, thereby limiting the range of rotation angle between the first support 100 and the second support 200.

[0054] It is understandable that by providing an abutment protrusion 202 on one of the first bracket 100 and the second bracket 200, and providing an arc groove 102 on the other, and the abutment protrusion 202 being able to slide in the arc groove 102, the relative rotation of the first bracket 100 and the second bracket 200 is guided, making the rotation of the first bracket 100 and the second bracket 200 more stable.

[0055] Specifically, the first connecting part 121 of the first fixing seat 120 is provided with an arc-shaped groove 102, and the second limiting part 222 of the second fixing seat 220 is provided with an abutting protrusion 202.

[0056] In a further embodiment of the present invention, the first bracket 100 and the second bracket 200 are respectively provided with abutment protrusions 202, the first bracket 100 is provided with an arc-shaped groove 102 corresponding to the abutment protrusion 202 on the second bracket 200, and the second bracket 200 is provided with an arc-shaped groove 102 corresponding to the abutment protrusion 202 on the first bracket 100.

[0057] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.

The first connecting part (121), the first limiting part (122), the second connecting part (221), and the second limiting part (222) together define the receiving cavity (600).

9. A smart glasses according to any one of claims 5 to 7, characterized in that, The first bracket (100) is provided with a first limiting structure, and the second bracket (200) is provided with a second limiting structure. When the first bracket (100) and the second bracket (200) rotate relative to each other to a preset angle, the first limiting structure and the second limiting structure abut against each other to restrict the rotation of the first bracket (100) and the second bracket (200).

10. The smart glasses according to claim 9, characterized in that, One of the first limiting structure and the second limiting structure is an abutment protrusion (202), and the other is an arc-shaped groove (102). The abutment protrusion (202) is slidably disposed in the arc-shaped groove (102). When the first bracket (100) and the second bracket (200) rotate relative to each other to a preset angle, the two side walls of the arc-shaped groove (102) in the circumferential direction of the rotation axis (300) can abut against the abutment protrusion (202) to restrict the rotation of the first bracket (100) and the second bracket (200).
