Description

Technical Field

[0001] This application belongs to the field of eyewear technology, and in particular relates to an eyewear hinge structure and smart glasses. Background Technology

[0002] In existing technologies, the temples and frames of smart glasses use flexible circuit boards for power supply and signal transmission. When the flexible circuit board passes through the hinge structure, it is usually exposed to the outside without any protective structure. Long-term repeated bending and friction can easily cause the insulation layer on the surface of the flexible circuit board to wear down or even break the circuit, which seriously affects the service life and reliability of the product. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems by providing a glasses hinge structure and smart glasses that can solve the above-mentioned technical issues.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A glasses hinge structure includes a base, a first arm that slides relative to the base, and a second arm that is hinged to one end of the first arm. The first arm has a wire channel that extends along the sliding direction of the first arm and passes through the end of the first arm near the base and the end that is hinged to the second arm. A flexible circuit board can pass through the wire channel from inside the second arm and be led out from the base.

[0005] Furthermore, the threading channel is provided with a guide hole at the end near the second support arm, and the diameter of the guide hole is larger than the inner diameter of the remaining part of the threading channel.

[0006] Furthermore, at least a portion of the first arm is inserted into the guide groove of the base.

[0007] Furthermore, the second arm has a redundant space, and the guide hole is placed in the redundant space. The flexible circuit board enters the wiring channel from the redundant space through the guide hole.

[0008] Furthermore, the second arm includes a first abutment surface and a second abutment surface that are in contact with the base. The first abutment surface and the second abutment surface are connected by a transition profile. The first abutment surface and the second abutment surface are set at an angle. The second arm rotates about the hinge point so that the first abutment surface or the second abutment surface comes into contact with the base.

[0009] Furthermore, the eyeglass hinge structure also includes an elastic component at least partially fitted onto the base, the remaining portion of which is connected to the first arm.

[0010] Furthermore, the elastic component includes a spring and an adapter, and a support extending along the sliding direction of the first support arm is also provided on the base. The spring is sleeved on the support, and the adapter is connected to the first support arm through an elastic adjustment member.

[0011] Furthermore, the adapter is also provided with a guide hole, through which the adapter is sleeved onto the support column.

[0012] Furthermore, the elastic adjustment component is threaded or connected to the adapter component via a convex-concave fit. By screwing or moving the elastic adjustment component, the axial position of the adapter component on the support can be changed, thereby adjusting the preload of the spring.

[0013] As an application, this application also provides a smart glasses, including a frame and temples each having a receiving space, and an electronic functional module disposed in the frame and temples. The frame is rotatably connected to the temples via a glasses hinge structure. Either the base or the second arm is fixedly placed in the receiving space of the frame, and the other is fixedly placed in the receiving space of the temple.

[0014] Compared with existing technologies, the advantages of this application are as follows: by setting a through-type wiring channel inside the first arm, a protected and optimized wiring space is provided for the flexible circuit board. This fundamentally solves the reliability problems of flexible circuit boards in existing technologies, such as easy wear, corrosion, and pinching, greatly extending the service life of smart glasses. At the same time, while ensuring structural strength, the weight of the hinge mechanism is reduced, making the entire hinge mechanism lighter. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0018] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0021] Example 1

[0022] like Figures 6-9 As shown, a glasses hinge structure includes a base 1 supporting various components, and a first arm 2 sliding relative to the base 1. At least a portion of the first arm 2 is inserted into a guide groove 11 of the base 1. A second arm 3 is hinged to the end of the first arm 2 away from the base 1. In the prior art, the temples and frames of smart glasses use flexible circuit boards for power supply and signal transmission. When the flexible circuit board passes through the hinge structure, it is usually directly exposed to the outside without a protective structure, or additional components are needed to protect the flexible circuit board. Such designs increase the number of components, thereby increasing the processing steps and the overall weight of the glasses. In this embodiment, as... Figure 3 As shown, by providing a wire-passing channel 21 in the first arm 2, the flexible circuit board is protected by the wire-passing channel 21 and will not be directly exposed to the outside. At the same time, the first arm 2 with the wire-passing channel 21 not only simplifies the number of components, but also reduces the weight of the hinge mechanism while ensuring structural strength, making the entire hinge mechanism lighter.

[0023] Specifically, the wire channel 21 extends along the sliding direction of the first arm 2 and passes through the end of the first arm 2 near the base 1 and the end hinged to the second arm 3. The flexible circuit board can pass through the wire channel 21 from inside the second arm 3 and be led out from the base 1. Through this through-channel design, the flexible circuit board is always wrapped and guided by the structure of the first arm 2 during the opening and closing of the temple, which avoids direct friction with moving parts and prevents fatigue breakage of the circuit due to repeated bending.

[0024] Furthermore, the cross-sectional shape of the wiring channel 21 matches the width of the flexible circuit board, and a smooth-transition rounded corner structure is provided on the inner wall to effectively reduce the resistance of the flexible circuit board's micro-movements. When the second arm 3 rotates relative to the first arm 2, the flexible circuit board can avoid excessive bending within the wiring channel 21.

[0025] The above solution not only eliminates redundant parts such as independent cable protection covers and fixing clips, but also achieves cable protection, guidance and space optimization functions while maintaining the original size of the hinge through the integrated design of structure and function.

[0026] In addition, such as Figure 4 and Figure 9As shown, the wiring channel 21 has a guide hole 211 at the end near the second arm 3. The guide hole 211 provides a loose transition area for the flexible circuit board to bend at the hinge point between the second arm 3 and the first arm 2. The diameter of the guide hole 211 is larger than the inner diameter of the remaining part of the wiring channel 21. A redundant space 33 is provided in the second arm 3, and the guide hole 211 is placed within the redundant space 33. The flexible circuit board enters the wiring channel 21 from the redundant space 33 through the guide hole 211. The redundant space 33 provides a necessary "hysteresis" area for the flexible circuit board near the hinge point. During the repeated opening and closing of the temple, the required length of the flexible circuit board will change slightly. This redundant space 33 allows the flexible circuit board to be partially stacked internally, thereby absorbing this length difference and fundamentally eliminating the pulling phenomenon caused by insufficient length margin, ensuring the long-term stability of power and signal transmission.

[0027] like Figure 1 As shown, regarding the second arm 3, in this embodiment, the second arm 3 is at least partially in contact with the base 1. Specifically, the second arm 3 includes a first abutment surface 31 and a second abutment surface 32 that are in contact with and connected to the base 1. The first abutment surface 31 and the second abutment surface 32 are connected by a transition contour. The first abutment surface 31 and the second abutment surface 32 are set at an angle. The second arm 3 rotates around the hinge point so that the first abutment surface 31 or the second abutment surface 32 contacts and abuts against the base 1, thereby defining the open and closed states of the temple respectively. The key point is that the transition contour is not a simple connecting surface, but a calculated curved surface. The interaction between this contour and the base 1 can guide the second arm 3 during the process of the temple folding inward to close, thereby forming a "semi-automatic" effect that assists the temple to close automatically after passing the dead point.

[0028] like Figure 2 As shown, to achieve the above-mentioned functional effects, in this embodiment, as... Figure 6 As shown, a glasses hinge structure also includes an elastic component 4 at least partially fitted onto the base 1. The remaining portion of the elastic component 4 is connected to the first arm 2. Specifically, the elastic component 4 includes a spring 41 and a connector 42. A support column 12 extending along the sliding direction of the first arm 2 is also provided on the base 1. The spring 41 is fitted onto the support column 12. The connector 42 is connected to the first arm 2 via a spring adjustment component 5. The connector 42 also has a guide hole 421, through which it is fitted onto the support column 12. The spring adjustment component 5 is the core drive and damping source for realizing the semi-automatic opening and closing and hovering function of the temples. The spring 41 fitted onto the support column 12 is always in a compressed state, and its released elastic force is continuously transmitted to the first arm 2 through the connector 42, and then to the second arm 3 hinged to the first arm 2. This constant force ensures that a stable and controllable frictional force can be generated between the first abutment surface 31, the second abutment surface 32, and the transition profile of the second arm 3 and the base 1.

[0029] Furthermore, the elastic adjustment component 5 is threaded or mattely connected to the adapter 42. By turning or moving the elastic adjustment component 5, the axial position of the adapter 42 on the support column 12 can be changed, thereby adjusting the preload of the spring 41. During the assembly stage, the operator can precisely fine-tune the preload of the spring 41 by turning the elastic adjustment component 5, thereby compensating for the manufacturing tolerances of the parts and the cumulative assembly errors, ensuring that each hinge can obtain consistent damping and suspension force. If the hinge wears down after long-term use, resulting in a decrease in preload, it is not necessary to replace the entire hinge. It can be restored to the standard pressure value simply by using this adjustment mechanism, which greatly improves the maintainability and service life of the product.
