Description

Technical Field

[0001] This utility model relates to the field of eyeglasses technology, and in particular to a rotating component and eyeglasses. Background Technology

[0002] In traditional eyewear designs, the rotating connection between the frame and temples is typically simple, its function limited to allowing the temples to fold inwards for easy storage in a case. Existing technologies generally employ a simple pivot hinge, allowing the temples to rotate in one direction on a fixed axis. This traditional structure has limitations: its function is singular, the temples can only fold inwards, and it cannot adjust the outward angle according to the user's head size or wearing comfort, resulting in insufficient adaptability. Furthermore, because the hinge's rotation center is fixed, the trajectory of the temple's end during folding occupies a large envelope space, preventing the temples from folding more compactly and hindering further reduction in case size, thus limiting portability. Utility Model Content

[0003] Based on this, it is necessary to provide a rotating assembly and eyeglasses, wherein the sliding member enables the rotating seat to move away from the fixed seat and to rotate relative to the fixed seat; and the elastic member enables the connection between the fixed seat and the rotating seat to be maintained and prevent the two from completely separating, so that the rotating seat can rotate relative to the fixed seat after being separated from it by a certain distance, thereby achieving outward bending.

[0004] An embodiment of this utility model provides a rotating assembly, including a fixed base, a rotating base, and an adjusting member. The adjusting member includes a sliding member and an elastic member connected to each other. One end of the sliding member is rotatably connected to the fixed base, and the other end is slidably and rotatably connected to the rotating base. One end of the elastic member is connected to the sliding member, and the other end is connected to the rotating base.

[0005] In one embodiment, the sliding member includes a first mounting portion and a second mounting portion connected to each other. The first mounting portion is rotatably connected to the fixed seat, and the second mounting portion is slidably connected to the rotating seat. One end of the elastic member is connected to the second mounting portion.

[0006] In one embodiment, the second mounting part is provided with a first fixing rod, the rotating seat is provided with a second fixing rod, the first fixing rod and the second fixing rod are parallel to each other, one end of the elastic member is rotatably connected to the first fixing rod, and the other end is rotatably connected to the second fixing rod.

[0007] In one embodiment, the elastic element includes a first connecting part, a compression part, and a second connecting part connected in sequence. Both the first connecting part and the second connecting part have a hook structure. The first connecting part is hung on the first fixed rod through the hook structure, and the second connecting part is hung on the second fixed rod through the hook structure.

[0008] In one embodiment, the second mounting part is provided with a slide rod, the rotating seat is provided with a slide groove, and the slide rod is slidably connected in the slide groove.

[0009] In one embodiment, the first mounting part and the second mounting part are arranged along a first direction, and the rotating seat is provided with two first mounting walls spaced apart and opposite each other along a second direction.

The second mounting part is located between the two first mounting walls. The second mounting part is provided with sliding rods on opposite sides along the second direction, and the sliding rods are slidably disposed in the sliding grooves one by one.

[0011] In one embodiment, the slide has a bent structure and extends to the edge of the rotating seat to form an opening through which the slide rod can be inserted into the slide.

[0013] A pair of eyeglasses includes a frame, temples, and the aforementioned rotating assembly, wherein one of the fixed base and the rotating base is fixedly connected to the frame, and the other is fixedly connected to the temples.

[0014] The rotating assembly and eyeglasses provided in this application have a sliding member with one end rotatably connected to a fixed base, allowing the entire sliding member to rotate freely around the fixed base. The other end is slidably connected to a rotating base, giving the rotating base two degrees of freedom of movement. It can be driven by an external force to move away from or towards the fixed base along the sliding direction, achieving linear movement. While moving or after reaching a certain position, the rotating base can further rotate relative to the fixed base. The elastic member maintains the connection between the fixed base and the rotating base, preventing them from completely separating. This allows the rotating base to rotate relative to the fixed base after separating it a certain distance, thereby achieving outward bending. Attached Figure Description

[0017] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0021] In traditional eyewear designs, the rotating connection between the frame and temples is typically simple and straightforward. The core design goal is simply to allow the temples to fold inwards for easy storage in a case. Existing technologies generally employ a simple pivot hinge, allowing the temples to rotate in one direction on a fixed axis. Therefore, this traditional structure has limitations: its function is singular; the temples can only fold inwards and cannot be adjusted outwards according to the user's head size or wearing comfort (i.e., they cannot "puff out"), resulting in insufficient adaptability. Furthermore, because the hinge's rotation center is fixed, the trajectory of the temple's end during folding occupies a large envelope space, preventing the temples from folding more compactly and hindering further reduction in case size, thus limiting portability.

[0022] Reference Figures 1-5 In an embodiment of this utility model, a rotating assembly 10 is provided, including a fixed base 100, a rotating base 200, and an adjusting member 300. The adjusting member 300 includes a sliding member 310 and an elastic member 320 connected to each other. One end of the sliding member 310 is rotatably connected to the fixed base 100, and the other end is slidably and rotatably connected to the rotating base 200. One end of the elastic member 320 is connected to the sliding member 310, and the other end is connected to the rotating base 200.

[0023] Specifically, to solve the above problems, in this embodiment, the rotating assembly 10 includes a fixed base 100, a rotating base 200, and an adjusting member 300. The fixed base 100 is the stationary part of the rotating assembly 10. For example, when the rotating assembly 10 is applied to eyeglasses, the fixed base 100 is firmly installed on the main structure of the eyeglasses, such as the frame 400 or the temple 500, to provide a stable foundation for the entire rotation process. The rotating base 200 is the movable part of the rotating assembly 10, and the rotating part is connected to the component that needs to be driven. For example, the rotating base 200 is located on the temple 500. The rotating base 200 can rotate at a certain angle based on the fixed base 100, thereby realizing the functions of opening and closing or angle adjustment. The adjusting member 300 is composed of a sliding member 310 and an elastic member 320. One end of the slider 310 forms a reliable rotatable connection with the fixed base 100, allowing it to swing. The other end of the slider 310 is connected to the rotating base 200 via a sliding mechanism, allowing the rotating base 200 to generate relative linear displacement with the slider 310 during movement. Furthermore, an elastic element 320 is connected between the slider 310 and the rotating base 200. The elastic element 320 provides a continuous elastic restoring force. When the rotating base 200 is subjected to an external force and begins to rotate, it stretches or compresses the elastic element 320. The energy stored in the elastic element 320 tends to cause the rotating base 200 to return to its original or a certain equilibrium position. This arrangement of the rotating assembly 10 not only makes the rotation process smoother and more controllable but also effectively buffers impacts and provides a clear feel when rotating to a specific position, improving the user experience. The rotating assembly 10 provided in this application has a sliding member 310 that allows the rotating seat 200 to move away from the fixed seat 100 and to rotate relative to the fixed seat 100; while the elastic member 320 can maintain the connection between the fixed seat 100 and the rotating seat 200 and prevent the two from completely separating. In this way, the rotating seat 200 can rotate relative to the fixed seat 100 after being separated from it by a certain distance, thereby achieving outward bending.

[0024] Furthermore, the slider 310 includes a first mounting portion 311 and a second mounting portion 312 connected to each other. The first mounting portion 311 is located at one end of the slider 310 and is rotatably connected to the fixed seat 100 via a pivot or hinge structure, allowing the slider 310 to rotate around the fixed seat 100, providing a basic rotational capability for the rotating assembly 10. The second mounting portion 312 is located at the other end of the slider 310 and is connected to the rotating seat 200 via a sliding mechanism. This connection allows the rotating seat 200 to slide linearly along a specific direction on the second mounting portion 312, thereby adjusting the distance between the two components. This not only ensures the freedom of movement but also ensures the stability of the structure during sliding. One end of the elastic member 320 is connected to the second mounting portion 312, enabling the elastic member 320 to directly sense and respond to the relative movement between the slider 310 and the rotating seat 200. When the rotating seat 200 slides, it will pull or compress the elastic element 320, causing it to produce corresponding elastic deformation, thereby providing the necessary buffering force, restoring force or damping effect to ensure the smoothness of the movement process.

[0025] Specifically, in this embodiment, a first fixing rod 312a is provided on the second mounting part 312, and correspondingly, a second fixing rod 220 is provided on the rotating seat 200. The first fixing rod 312a and the second fixing rod 220 are kept parallel to each other in space, and the parallel relationship between the first fixing rod 312a and the second fixing rod 220 can ensure the accuracy of the movement trajectory of the subsequent connected components. The elastic element 320 provides elastic restoring force, and both ends of the elastic element 320 form a rotatable connection relationship with the first fixing rod 312a and the second fixing rod 220, respectively. Specifically, one end of the elastic element 320 is rotatably fitted or hung on the first fixing rod 312a of the second mounting part 312, and the other end is rotatably connected to the second fixing rod 220 of the rotating seat 200. The rotatable connection provides the elastic element 320 with a degree of freedom during the movement of the component. When the rotating seat 200 moves or rotates relative to the fixed seat 100, it will drive the second fixing rod 220 to move together, thereby pulling one end of the elastic element 320 to move. At this point, since both ends of the elastic element 320 are rotatably connected, it can not only undergo tensile or compressive deformation, but also adaptively adjust its angle, effectively avoiding motion interference or jamming. Throughout the process, the elastomer consistently applies elastic force to the component, ensuring smooth movement and providing a stable reset function.

[0026] In one embodiment, the elastic element 320 includes a first connecting portion 321, a compression portion 322, and a second connecting portion 323 connected in sequence. The first connecting portion 321 is located at one end of the elastic element 320, and its end has a specific hook structure. This hook structure allows the first connecting portion 321 to be securely and flexibly connected to the first fixing rod 312a of the second mounting portion 312 in a suspended manner, simplifying the installation process. Simultaneously, the suspended manner allows the elastic element 320 to rotate slightly around the fixing rod when subjected to force, thereby adapting to angular changes during movement and avoiding unnecessary stress concentration. The compression portion 322 is the middle part of the elastic element 320 and can be made of a material capable of elastic deformation. When the component moves, the compression portion 322 can be stretched or compressed, storing and releasing elastic potential energy, thereby providing the necessary buffering force, damping sensation, and automatic return-to-center reset function for the entire rotating connection, ensuring smooth operation. The second connecting part 323 is located at the other end of the elastic member 320, corresponding to the first connecting part 321. The end of the second connecting part 323 is also provided with a hook structure. The hook is directly suspended on the second fixed rod 220 of the rotating seat 200, forming a rotatable connection point at the other end. The above symmetrical structure ensures that the elastic member 320 is subjected to uniform force at both ends, so that it can remain stable during operation.

[0027] Furthermore, a slide rod 312b is provided on the second mounting portion 312, and correspondingly, a groove 211 is provided on the rotating seat 200 to cooperate with it. The slide rod 312b and the groove 211 together constitute a sliding connection mechanism, enabling relative linear movement between the rotating seat 200 and the second mounting portion 312. The slide rod 312b can be a precision-machined cylindrical or a protruding structure with a specific guide shape, and is fixedly installed at a specific position on the second mounting portion 312. The slide rod 312b acts as a guide shaft, determining the sliding path and direction. The groove 211 on the rotating seat 200 has a shape that matches the cross-sectional shape of the slide rod 312b, providing a precise moving track for the slide rod 312b. In one embodiment, the interior of the groove 211 is smooth and flat to ensure that the slide rod 312b can slide smoothly back and forth within it with extremely low frictional resistance. During operation, the slide rod 312b is nested within the groove 211. When an external force is applied to the rotating seat 200, the rotating seat 200 will transmit the force to the slide rod 312b through the slide groove 211, and drive it to move smoothly in a straight line relative to the second mounting part 312 along the trajectory defined by the slide groove 211.

[0028] Furthermore, the first mounting portion 311 and the second mounting portion 312 are arranged along the first direction, and a pair of first mounting walls 210 are provided on the rotating seat 200, spaced apart and arranged opposite each other along the second direction. The second direction is perpendicular to the arrangement direction of the first mounting portion 311 and the second mounting portion 312. The perpendicularity between them allows the two first mounting walls 210 to effectively surround and support the second mounting portion 312 from both sides. A groove 211 is machined on the first mounting wall 210, and the positions of the grooves 211 correspond to each other, forming a double track system. The main structure of the second mounting portion 312 is located between the two opposing first mounting walls 210. In order to cooperate with the structure of the groove 211 on the rotating seat 200, outwardly protruding slide rods 312b are machined on the two opposite outer surfaces of the second mounting portion 312 along the second direction. Each slide bar 312b is nested and slidably installed in its corresponding slide groove 211. The structure of simultaneous sliding on both sides improves the stability of the movement and can effectively prevent the second mounting part 312 from tilting, jamming or derailing during the sliding process, ensuring a smooth sliding process and thus extending the service life of the rotating assembly 10.

[0029] Furthermore, in this embodiment, the second mounting portion 312 is provided with two second mounting walls 312c spaced apart and opposite each other along the second direction. The two second mounting walls 312c are parallel and opposite, forming a symmetrical support structure, which can effectively improve the torsional and bending resistance under stress. Each second mounting wall 312c is provided with a slide rod 312b. The axes of the slide rods 312b are parallel to each other, ensuring the balance of forces on both sides and the consistency of movement during subsequent sliding. In one embodiment, the slide rod 312b has a cylindrical structure, with a straight generatrix and a circular cross-section, ensuring that when the slide rod 312b is engaged with the slide groove 211, its contact surface with the inner wall of the slide groove 211 and the stress condition remain uniform and consistent, regardless of its position in the sliding stroke. Specifically, the elastic element 320 is located in the space between the two second mounting walls 312c. The mounting walls on both sides provide effective lateral protection for the elastic element 320, preventing it from falling off or deforming due to external interference or accidental collisions. At the same time, the symmetrical arrangement allows the elastic element 320 to be in a more symmetrical deformation state when subjected to force, thereby providing a more stable and elastic restoring force.

[0030] In some embodiments, the slide 211 has a bent structure, extending to the edge of the rotating seat 200 to form an opening 211a. The slide rod 312b can be inserted into the slide 211 through the opening 211a, so that the path of the slide 211 can be planned according to actual motion requirements, possibly including angle changes or curved transitions, thereby guiding the slide rod 312b to move along a predetermined trajectory during sliding. One end of the slide 211 extends and penetrates to the edge region of the rotating seat 200, forming an opening 211a. The opening 211a is the channel for the slide rod 312b to enter the interior of the slide 211. Specifically, during assembly, the user can precisely align the slide rod 312b with the opening 211a and then apply appropriate force to make the slide rod 312b embed into the internal track of the slide 211 through this opening 211a. Once the slide rod 312b is fully inserted into the slide 211, a complete sliding connection is formed between the rotating seat 200 and the second mounting part 312. During normal use, due to the bending structure or closed end design of the slide groove 211, the slide rod 312b will not accidentally come out of the opening 211a, thus ensuring the safety and reliability of the connection.

[0031] The eyeglasses of the second aspect of this utility model include a frame 400, temples 500, and a rotating assembly 10 as described in the first aspect. One of the fixed base 100 and the rotating base 200 is fixedly connected to the frame 400, and the other is fixedly connected to the temple 500. Since this embodiment adopts all the technical features of the rotating assembly 10 of the first aspect embodiment, this embodiment possesses all the beneficial effects brought by the first aspect embodiment, which will not be repeated here.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
