[0024] The working principle and beneficial effects of the present utility model are as follows:

[0025] In the present utility model, the smart glasses change the traditional fixed temple body structure and design it into a telescopic hinge structure to adjust some outward output function sockets on the temple part, such as audio playback sockets and other output sockets, which can realize the distance adjustment of the audio sound source position to the ear position, so that users can better experience the output of the sound source during use. At the same time, for the comfort of people with different head sizes wearing glasses, the telescopic hinge structure can meet the pursuit of comfort by more people.

[0026] The temple body with an output socket can be slidably arranged on the hinge body composed of fixed parts such as lenses and frames to complete the assembly of the entire smart glasses. For different needs, the temple body can be slid in advance to adjust the position of the output socket on it relative to the hinge body to ensure a more comfortable and better experience.

[0027] Specifically, the sliding form can be diverse. For example: a slide rail type sliding structure, where mutually cooperating slide rails and sliders are respectively provided on the temple body and the hinge body. The slider is installed on the temple body, and the slide rail is provided on the hinge body.

[0043] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will describe the specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can be obtained.

In addition, to make the drawings concise and easy to understand, in some drawings, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also means "more than one" situation, and "several" includes "two" and "more than two".

[0045] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0046] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0047] Referring to Figures 1 to 12 , for the first embodiment of the present invention, a telescopic hinge for smart glasses is proposed, including: a hinge body 1; a temple body 2, the temple body 2 is slidably arranged on the hinge body 1, the temple body 2 has an output port 301, and after the temple body 2 slides, the output port 301 is close to or far from the hinge body 1.

[0048] In this embodiment, as Figures 1 - 4 shown, by changing the structure of the traditional fixed temple body 2, the smart glasses are designed as a telescopic hinge structure to adjust some outward output function sockets at the temple part 3, such as the output port 301 like the audio playback port, etc., which can realize the distance adjustment of the audio sound source position to the ear position, enabling the user to better experience the output of the sound source during use. At the same time, for the comfort of people with different head sizes when wearing glasses, the telescopic hinge structure can meet the pursuit of comfort by more people.

[0049] The temple body 2 with an output port 301 is slidably arranged on the hinge body 1 composed of fixed components such as lenses and frames to complete the assembly of the entire smart glasses. For different requirements, the temple body 2 can be slid in advance to adjust the position of the output port 301 thereon relative to the hinge body 1, ensuring a more comfortable and better experience.

[0050] Specifically, the sliding form can be various. For example: a slide rail type sliding structure, in which mutually cooperating slide rails and sliders are respectively arranged on the temple body 2 and the hinge body 1. The slider is installed on the temple body 2, and the slide rail is arranged on the hinge body 1. The slider can be made of wear-resistant plastic or metal materials to ensure smoothness during multiple sliding processes. The shape of the slide rail can be designed as a "T" shape or a "U" shape to better limit the moving direction of the slider and prevent the temple body 2 from detaching from the hinge body 1 during sliding. This structural form is simple and easy to implement, and multiple positioning grooves can be arranged on the slide rail. When the temple body 2 slides to a specific position, the slider can be snapped into the positioning groove to fix the temple body 2, meeting the needs of different users for the position of the output port 301; Another example: a ball type sliding structure, in which a row of balls is arranged between the temple body 2 and the hinge body 1. Grooves for installing balls can be respectively opened on the temple body 2 and the hinge body 1, and the balls are placed in the grooves, enabling the temple body 2 to slide on the hinge body 1 through the balls. High-precision steel balls can be selected for the balls to ensure smoothness and stability of sliding. To prevent the balls from falling off, retaining plates can be arranged at both ends of the groove. This sliding structural form has a small friction force and is easier to slide, providing a more comfortable adjustment experience for users. At the same time, a positioning bolt can be arranged on the temple body 2. After adjusting to the appropriate position, the positioning bolt is tightened to make it contact with the hinge body 1 to generate friction force, thereby fixing the position of the temple body 2; Another example: a gear and rack type sliding structure, in which a rack is installed on the temple body 2, and a gear meshing with the rack is installed on the hinge body 1. By rotating the gear, the temple body 2 can be driven to slide on the hinge body 1. The gear can be arranged on the outside of the hinge body 1 for convenient operation by users. To ensure the meshing accuracy of the gear and the rack, a high-precision processing technology can be adopted. This sliding structural form can achieve more precise position adjustment and has good stability. A dial can be arranged on the gear, and users can accurately adjust the position of the temple body 2 according to the indication on the dial to meet the highly personalized needs of different users for the position of the output port 301.

[0051] All in all, it is only necessary to ensure that the temple body 2 can stably slide on the hinge body 1 to adjust the overall length and the position of the output port 301 to meet more requirements.

[0052] Furthermore, the temple body 2 includes: a temple portion 3 and a connection limit portion 4, the connection limit portion 4 is detachably arranged on the temple portion 3, and the connection limit portion 4 is slidably arranged on the hinge body 1, the temple portion 3 has an output port 301, and after the connection limit portion 4 slides, the output port 301 is close to or away from the hinge body 1.

[0053] In this embodiment, Figures 2 - 5 As shown in Figure 10, the temple body 2 is further divided into the temple part 3 and the connection limit part 4. This is because the carrier of the smart glasses is too complicated, and a huge structure and control systems such as circuits need to be concentrated on one component to facilitate subsequent loading and unloading and maintenance. If the entire temple body 2 is the carrier structure, the entire layout will be relatively scattered, which does not meet actual needs and cannot meet refined needs. Therefore, the carrier structure is concentrated on the temple part 3, so that the output port 301 is located on the temple part 3. In order to ensure that the sliding function can be normally realized, the connection limit part 4 is detachably connected to the temple part 3. The temple part 3 slides on the hinge body 1 through the connection limit part 4. Due to the detachability and slidability of the connection limit part 4, the user can customize the temple according to his or her preferences and needs. The connection limit part 4 of different colors, materials or shapes can be selected to make the smart glasses more in line with personal style. By adjusting the position of the output port 301, the user can optimize the audio output effect according to his or her usage habits and preferences to achieve a truly personalized customization experience.

[0054] Furthermore, the hinge body 1 has a limit block 101, the connection limit part 4 is plate-shaped, and the connection limit part 4 has a plurality of limit grooves 401, and the plurality of limit grooves 401 are arranged along the sliding direction of the connection limit part 4. After the connection limit part 4 slides, the limit block 101 is used to be inserted into one of the limit grooves 401.

[0055] In this embodiment, Figure 4 , 5 As shown in Figure 11, in order to improve the position accuracy after adjustment and the overall stability, a slide rail sliding structure is adopted. Specifically, a limit block 101 in the form of a damping marble is adopted on the hinge body 1, and a plurality of limit grooves 401 are provided on the connection limit part 4 along its sliding direction. One limit groove 401 can be provided every 3 mm, and a total of 4 limit grooves are provided to meet most of the needs; when the limit block 101 is inserted into the limit groove 401, it can effectively prevent the connection limit part 4 from shaking or shifting during use, which is very important for the overall stability of the smart glasses, especially when the user is engaged in activities such as walking, exercising, etc., without affecting the wearing comfort and the quality of the audio output.

[0056] Furthermore, a protective groove 302 is formed at one end of the temple portion 3 close to the hinge body 1 , and the hinge body 1 and the limiting block 101 are both located in the protective groove 302 .

[0057] In this embodiment, as Figure 10 , 11 shown, on the basis of the split setting of the temple body 2, a protection groove 302 is provided at one end of the temple part 3 close to the hinge body 1. After installation, both the hinge body 1 and the limit block 101 can be located within the protection groove 302, playing a role in stable protection, wrapping some structural components, and also making the entire structure more aesthetically pleasing. It ensures that after long-term use, the limit block 101 in the form of a damping marble can also function normally within the protection groove 302, improving the service life.

[0058] Furthermore, the protection groove 302 has an opening 303, and the connecting limit part 4 is detachably arranged at the opening 303. The limit groove 401 communicates with the protection groove 302. One end of the connecting limit part 4 has an annular part 402, and the hinge body 1 passes through the annular part 402.

[0059] In this embodiment, as Figures 2 - 5 , 10, 11 shown, an opening 303 is provided in the protection groove 302 to facilitate the installation of the connecting limit part 4 therein, so as to adapt to the structural layout for the protection groove 302 to play its role. Further, an annular part 402 is prefabricated at one end of the connecting limit part 4 in advance, aiming to make the entire sliding adjustment process more stable and prevent detachment. Therefore, the hinge body 1 passes through the entire annular part 402.

[0060] Furthermore, the cross-sectional shape of the hinge body 1 is adapted to the inner shape of the annular part 402. The hinge body 1 also has a guiding surface 102. The top of the protection groove 302 also has an installation groove 304. The inner ring of the annular part 402 has an installation part 403, and the installation part 403 is located within the installation groove 304 and abuts against the guiding surface 102. After the connecting limit part 4 slides, it drives the installation part 403 to slide relative to the guiding surface 102.

[0061] In this embodiment, as Figures 2 - 5 , 10, 11 shown, the hinge body 1 passes through the entire annular part 402. To ensure that it will not shake randomly, the cross-sectional shape of the hinge body 1 is adapted to the inner shape of the annular part 402. Also, a guiding surface 102 is provided on the hinge. The installation part 403 of the inner ring of the annular part 402 always abuts against the guiding surface 102 during the entire adjustment and sliding process, realizing the limitation of two degrees of freedom. The adjustment of the entire temple body 2 is more stable. At the same time, an installation groove 304 needs to be provided in the protection groove 302 to make way for the position of the installation part 403.

[0062] Furthermore, the other end of the connecting limit part 4 also has an installation post 404, and the bottom of the protection groove 302 also has an installation hole 305. The installation post 404 is arranged at the installation hole 305 through a fastener.

[0063] In this embodiment, asFigures 2 - 5 As shown in FIGS. 10 and 11, in order to improve the installation stability of the connection limiting portion 4 installed at the opening 303 on one side of the protection groove 302 relative to the whole, an installation post 404 is prefabricated in advance at one end far from the annular portion 402. A lateral installation hole 305 is correspondingly provided in the mirror leg 3, specifically at the bottom of the protection groove 302 to ensure communication. After being successfully installed into the installation hole 305, the installation portion 403 is locked at the installation hole 305 through fasteners such as bolts, which has a fixed limiting effect on the connection limiting portion 4 from both ends.

[0064] Furthermore, it further includes: two blocking portions 5. The two blocking portions 5 are arranged at intervals on the connection limiting portion 4. A plurality of limiting grooves 401 are all located between the two blocking portions 5. One end of the hinge main body 1 extending into the protection groove 302 has a protruding portion 103. The hinge main body 1 is L-shaped. The protruding portion 103 has a limiting block 101. The limiting block 101 is a damping marble. After the connection limiting portion 4 slides, the protruding portion 103 abuts or cancels abutting against one of the blocking portions 5.

[0065] In this embodiment, as Figures 4 - 7 shown, the L-shaped hinge main body 1 can be stably restricted between the two sets of blocking portions 5 on the connection limiting portion 4. A limiting block 101 in the form of a damping marble is installed on the protruding portion 103 of the L-shape. The extreme positions of sliding are the blocking portions 5 at both ends, providing the function of a positioning retaining wall, and at the same time, it does not affect the function of the limiting grooves 401 between the two sets of blocking portions 5.

[0066] Furthermore, the hinge main body 1 further has a hollow cavity 104. It further includes: an installation main body 6 and a connecting rod 7. One end of the connecting rod 7 is hingedly arranged on the installation main body 6. The connecting rod 7 is located in the hollow cavity 104. The connecting rod 7 is used to connect the installation main body 6 and the hinge main body 1; a fixing ring 8. The fixing ring 8 is sleeved on the connecting rod 7 and is fixedly connected to the hinge main body 1; an elastic member 9 and a fixing piece 10. The elastic member 9 is sleeved on the connecting rod 7. One end is fixedly connected to the fixing ring 8, and the other end is fixedly connected to the fixing piece 10. The fixing ring 8, the elastic member 9 and the fixing piece 10 are all located in the hollow cavity 104. The elastic member 9 is used to tightly connect the installation main body 6 and the hinge main body 1.

[0067] Furthermore, one end of the hinge main body 1 far from the protruding portion 103 has an abutting surface 105. The installation main body 6 has a hinge point 601, a closing surface 602, a transition protruding surface 603 and an opening surface 604. The distances between the opening surface 604 and the closing surface 602 and the hinge point 601 are both smaller than the distance between the transition protruding surface 603 and the hinge point 601. After the connecting rod 7 swings, the abutting surface 105 abuts against the closing surface 602, the transition protruding surface 603 and the opening surface 604 in sequence, and the elastic member 9 is used to be compressed and stretched in sequence.

[0068] In this embodiment, as Figures 6 - 11As shown in the figure, the hinge body 1 composed of fixed components such as lenses and frames is further divided into the mounting body 6 composed of completely stationary lenses and frames, etc., and the articulated part - connecting rod 7 that swings relative to it. One end of the connecting rod 7 is articulated on the mounting body 6 to complete the installation connection between the mounting body 6 and the hinge body 1, and finally form the entire smart glasses.

[0069] Regarding the use of the connecting rod 7, the fixing ring 8, the elastic member 9, and the fixing piece 10, it is to achieve the overall holding force and opening angle effect. The holding force mainly refers to the force that the spring enables the temple to closely fit the head. The opening angle refers to the angle formed between the temple and the frame plane when the temple is opened. When the glasses are worn on the head, the spring is in a certain degree of stretched state. This stretched state makes the spring tend to return to its original state, thus generating an inward pressure on the head. This pressure enables the temple to tightly hold the head and prevent the glasses from slipping off easily. For example, when performing some activities with a large amplitude of head shaking, such as running and jumping, the holding force of the spring can ensure that the glasses are always stably worn in the correct position. Among them, the spring plays a role in controlling the opening angle during the opening process of the temple. When you open the temple to prepare for wearing, the spring will gradually stretch, restricting the opening angle of the temple so that it will not open excessively. At the same time, when taking off the glasses, the compression and stretching of the spring will also affect the closing and opening states of the temple, ensuring that the temple can be smoothly opened and closed without suddenly bouncing open or being difficult to close.

[0070] To ensure the normal realization of the above functions, overall aesthetics, and improve the service life, a hollow cavity 104 is opened on the hinge body 1, and each component is installed therein. During installation, the fixing ring 8, the elastic member 9, and the fixing piece 10 are successively sleeved on the connecting rod 7, and the fixing ring 8 is fixedly connected to the hinge body 1 by riveting to prevent the above components from falling off from the hollow cavity 104 and complete the overall connection.

[0071] Working principle: The temple part 3 of the smart glasses is in a closed state. At this time, the elastic member 9 is stretched, and the abutting surface 105 of the hinge body 1 stably abuts against the closing surface 602 of the mounting body 6. Due to the acting force of the elastic member 9, it makes the process smoother and more stable during the gradual opening. The abutting surface 105 gradually abuts against the transition convex surface 603, and the elastic member 9 is compressed because the opening surface 604 and the closing surface 602 are both smaller than the distance between the transition convex surface 603 and the hinge point 601 from the hinge point 601. Then the abutting surface 105 gradually stably abuts against the opening surface 604 again, and the elastic member 9 is stretched to complete the whole process. The elastic member 9 plays a role in making the glasses more stable, comfortable, and convenient during wearing.
