Description

Technical Field

[0001] This utility model relates to the field of smart glasses technology, and more specifically to a rotating shaft device for glasses and smart glasses thereof. Background Technology

[0002] With the continuous improvement of chip computing power, the constant refinement of optical forms and parameters, and the ongoing advancements in technologies such as photography and transmission, the smart glasses industry as a whole has undergone a significant upgrade. Currently, the market offers a wide variety of AI smart glasses, some genuine and some not, using diverse optical modules. However, most smart glasses suffer from poor ergonomics in terms of fit and clamping force, resulting in a subpar user experience and reduced usage frequency. Furthermore, most smart glasses are not easily folded, making them inconvenient to carry and store. This is because current smart glasses frames are typically connected to the main body via welding or metal springs. This design has several drawbacks. First, the main body and frame cannot be separated, making them unsuitable for nearsighted individuals. Even with prescription lenses, these lenses are only suitable for those with corresponding vision, causing inconvenience for people with different vision levels and making it difficult to replace lenses of varying degrees. Therefore, the applicability of smart glasses is somewhat limited. Secondly, the metal spring connection is prone to loosening due to spring deformation, resulting in poor reliability. Secondly, glasses are typically worn by hooking the temples on both sides of the frame over the ears. As society develops, the number of people wearing glasses is gradually increasing. However, the hinge connecting the frame and temples in existing glasses is quite restrictive, limiting the temples to a rotation angle of only 90 degrees. Since everyone's head circumference and wearing habits are different, when the length of the frame is fixed and the wearer's head circumference is large, the temples tend to bend outwards. Although the glasses can still be worn, long-term use in this manner will result in two problems: first, the temples will deform significantly, gradually reducing the clamping force on the head; second, the wearer's comfort will be low, making it difficult to meet everyone's wearing needs.

[0003] Therefore, in view of the existing problems, how to provide a swivel device for eyeglasses and its smart glasses, so as to ensure that not only the temples can have good clamping force for wearers with different head sizes, but also that the smart glasses can be adapted to people with myopia and facilitate the replacement of myopia glasses, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] Therefore, this utility model provides a swivel device for eyeglasses and its smart glasses, which ensures that not only the temples can have good clamping force for wearers with different head circumferences, but also ensures that the smart glasses can be adapted to people with myopia and facilitate the replacement of myopia glasses.

[0041] Example 2:

[0042] See appendix Figure 3 This utility model discloses a smart glasses, including: the glasses hinge device, myopia frame 8, and multi-functional module as described in Embodiment 1; two temples 2; two glasses hinge devices; first connecting members 3 perpendicular to the glasses body 1 and fixed at both ends of the glasses body 1; and second connecting members 4 correspondingly fixed to the temples 2; the myopia frame 8 is detachably connected to the inner side of the glasses body 1; the multi-functional module includes a power module, a control module, and a display module; the power module and the control module are respectively fixed in the inner cavities of the two temples, and the control module is electrically connected to the power module; the display module is fixed to the glasses body 1.

[0044] To further optimize the above technical solution, a nose pad 9 is also included, which can be magnetically attached to the middle of the frame of the glasses body 1.

[0045] The method of use and working principle of this utility model are as follows:

[0046] The rotating mechanism has four working states: folded state, clamped state with an angle of less than 90 degrees between the temple and the lens frame, state with an angle of 90 degrees between the temple and the lens frame, and clamped state with an angle of greater than 90 degrees between the temple and the lens frame.

[0047] When the temples are folded, the second abutting surface of the first connector 1 abuts against the third abutting surface of the second connector 2, and the first connector 1 and the second connector 2 can maintain this state due to the elastic force of the spring 6.

[0048] When the temples are extended, the first contact surface of the first connector 1 abuts against the third contact surface of the second connector 2, and the first connector 1 and the second connector 2 can maintain this state due to the elastic force of the spring 6.

[0049] When the wearer's head circumference is smaller than the length of the lens frame, the pivot device is in a clamped state where the angle between the temple and the lens frame is less than 90 degrees. The abutting surface three in the second connector 2 abuts against the intersecting edge of the abutting surface one and the abutting surface two in the first connector 1. Due to the elastic force of the spring 6, the abutting surface three is forced to have an elastic tendency to abut against the abutting surface two again. This elastic tendency allows the temple fixed on the second connector 2 to clamp the wearer's head, ensuring the wearing effect.

[0050] When the wearer's head circumference is greater than the length of the lens frame, the pivot device is in a clamped state with an angle greater than 90 degrees between the temple and the lens frame. The abutment surface three in the second connector 2 disengages from the abutment surface one in the first connector 1, causing the temple to expand outward. The connecting plate three 44 can abut against the curved surface. Due to the elastic force of the spring 6, the abutment surface three is forced to have an elastic tendency to abut against the abutment surface one again. This elastic tendency allows the temple fixed on the second connector 2 to clamp the wearer's head, ensuring the wearing effect.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
