Description

Technical Field

[0001] This utility model relates to the field of eyeglass temple hinges, and particularly to a leaf spring structure for eyeglass temple hinges. Background Technology

[0002] Smart glasses are wearable devices integrating multiple technologies, featuring an independent operating system, interactive functions, and wireless network access capabilities. They can be controlled via voice or gestures to display information, monitor health, and perform augmented reality (AR) applications. Their core positioning lies between traditional glasses and smart terminals, encompassing sub-types such as XR (VR / AR / MR) and AI glasses, aiming to enhance the user experience through virtual-real fusion.

[0003] In existing smart glasses, the rotation and connection of the frame and temples are generally controlled by a spring-loaded connection mechanism. However, the existing spring-loaded mechanism requires a large installation space during design and installation to accommodate the length of the spring, which occupies a lot of space and may also affect the installation of other components, making it very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a leaf spring structure for the temple pivot of eyeglasses. The structure is ingenious and can greatly save the installation space between the temple and the frame, making it convenient and practical.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a first connecting body that can be installed and connected to the temple of a mirror and a second connecting body that can be installed and connected to the frame of a mirror; a connecting structure is provided between the first connecting body and the second connecting body, the connecting structure including a lifting body rotatably connected to the first connecting body and a mounting plate installed on the second connecting body, the first connecting body having a first mounting groove with openings on its bottom and side surfaces, the two ends of the lifting body being rotatably connected to the first mounting groove, the second connecting body having a second mounting groove, two parallel lifting rods fixedly provided at the bottom of the lifting body, the mounting plate having through holes through which each lifting rod can pass, and the mounting plate being installed on the second connecting body. On the mounting groove, a U-shaped leaf spring is provided between the bottom of the mounting plate and the second mounting groove. Each lifting rod corresponds to a leaf spring. Each lifting rod has a flat groove that is arranged opposite each other. The flat grooves on each lifting rod are all parallel. The upper end of the leaf spring acts on the bottom of the mounting plate. The lower end of each leaf spring has a slot corresponding to each lifting rod. The lower end of each leaf spring acts on the lifting rod through the insertion and cooperation of the flat groove on the corresponding lifting rod through the slot. During the rotation of the first connecting body and the second connecting body, the lifting body is lifted. After the first connecting body is rotated and unfolded or rotated and folded, the continuous force of each leaf spring drives each lifting rod and the lifting body on the lifting rod to return to its original position.

[0006] Furthermore, the bottom of the aforementioned mounting plate is provided with a mounting frame integrally formed with the mounting plate, and the bottom of the mounting plate is provided with a protrusion integrally formed with the mounting plate. The protrusion is provided with through holes corresponding to each lifting rod, and the through holes in the protrusion are arranged in parallel. The protrusion and the mounting frame form a groove into which the upper end of the leaf spring can be inserted. The groove is set with the same width as the upper end of the leaf spring. Multiple positioning pins are provided in the groove. The upper end of each leaf spring is provided with positioning holes corresponding to each positioning pin. The upper end of the leaf spring is positioned and set in the groove by the insertion and cooperation of each positioning pin with the positioning hole.

[0007] Furthermore, the upper end of the aforementioned leaf spring is provided with a lateral positioning plate integrally formed with the leaf spring. The extension direction of each lateral positioning plate is parallel to the leaf spring, and each lateral positioning plate is arranged parallel to the protrusion. Each lateral positioning plate is pressed against the side of the protrusion.

[0008] Furthermore, each leaf spring is provided with a reinforcing rib, which is integrally formed with the corresponding leaf spring and extends along the contour of the leaf spring.

[0009] Furthermore, both sides of the aforementioned lifting body are provided with rotating holes, and each rotating hole is equipped with a connecting shaft corresponding to that rotating hole. One end of each connecting shaft extending out of the rotating hole is provided with a connecting block integrally formed with the connecting shaft. The inner wall of the first mounting groove is provided with a connecting groove corresponding to each connecting block. The connecting block is fixed to the inner wall of the first mounting groove by inserting and engaging with the connecting groove. The lifting body is rotatably connected to the first mounting groove through the engagement of each connecting shaft and rotating hole.

[0010] This utility model has positive effects: (1) By setting a connection structure between the first connecting body and the second connecting body, the first connecting body is rotatably connected to the lifting body, and during the rotation of the first connecting body, the lifting body is lifted, and the lifting body is reset by the leaf spring set in the second mounting slot, which effectively ensures the stability of the first connecting body pressing against the second connecting body before and after rotation. At the same time, by setting the leaf spring, the leaf spring ensures the continuous action of the leaf spring on the mounting plate and the lifting rod by pressing against the mounting plate ground and by the cooperation of each slot and each flat slot. By replacing the compression spring mechanism in the traditional technology with the leaf spring, the internal space of the second mounting slot is effectively saved. The structure is ingenious, convenient and practical.

[0011] (2) This utility model provides a mounting frame at the bottom of the mounting plate and a protrusion at the bottom of the mounting plate. The positioning pin formed by the protrusion and the mounting frame can limit the leaf spring. The positioning pin can also be used to position one end of the leaf spring through the cooperation of the positioning pin and the positioning hole, thus ensuring the stability of the leaf spring during the force application process. It is convenient and practical.

[0012] (3) By setting a lateral positioning plate on the side of the leaf spring, the stability of the leaf spring during use is further ensured by pressing the protrusion with the lateral positioning plate, and the leaf spring is prevented from shifting laterally during use, which is safe and practical.

[0013] (4) By setting reinforcing ribs on the leaf spring, the service life and strength of the leaf spring can be increased, making it stable and practical.

[0014] (5) This utility model provides rotating holes on both sides of the lifting body, connects the rotating shaft to the rotating holes for rotational cooperation, and connects the connecting block to the inner wall of the first mounting groove for insertion cooperation, which ensures the stability of the connecting block and the connecting shaft during use, making it efficient and convenient.

A U-shaped leaf spring 33 is provided between the bottoms, and each lifting rod 34 corresponds to each leaf spring 33. Each lifting rod 34 has a flat groove 341 arranged opposite to each other. The flat grooves 341 on each lifting rod 34 are all arranged in parallel. The upper end of the leaf spring 33 acts on the bottom of the mounting plate 32, and the lower end of each leaf spring 33 has a slot 331 corresponding to each lifting rod 34. The lower end of each leaf spring 33 acts on the lifting rod 34 through the insertion and cooperation of the slot 331 with the flat groove 341 on the corresponding lifting rod 34. During the rotation of the first connecting body 1 and the second connecting body 2, the lifting body 31 is lifted. After the first connecting body 1 is rotated and unfolded or rotated and folded, the continuous force of each leaf spring 33 drives each lifting rod 34 and the lifting body 31 on the lifting rod 34 to return to the original position.

[0025] The bottom of the mounting plate 32 is provided with a mounting frame 321 integrally formed with the mounting plate 32. The bottom of the mounting plate 32 is provided with a protrusion 322 integrally formed with the mounting plate 32. The protrusion 322 is provided with through holes 325 corresponding to each lifting rod 34. The through holes 325 in the protrusion 322 are arranged in parallel. The protrusion 322 and the mounting frame 321 form a groove 323 into which the upper end of the leaf spring 33 can be inserted. The groove 323 is set with the same width as the upper end of the leaf spring 33. The groove 323 is provided with a plurality of positioning pins 324. The upper end of each leaf spring 33 is provided with a positioning hole 332 corresponding to each positioning pin 324. The upper end of the leaf spring 33 is positioned in the groove 323 by the insertion and cooperation of each positioning pin 324 with the positioning hole 332.

[0026] The upper end of the leaf spring 33 is provided with a lateral positioning plate 333 integrally formed with the leaf spring 33. The extension direction of each lateral positioning plate 333 is the same as that of the leaf spring 33.

[0029] The working principle of this utility model is as follows: During use, the first connecting body 1 is installed and connected to the temple A, and the second connecting body 2 is installed and connected to the frame B. When the temple A is in a folded state, the side of the first connecting body 1 presses against the mounting plate 32, and the first connecting body 1 and the second connecting body 2 are in a perpendicular state. During the rotation and unfolding of the temple A, the temple A rotates from a state parallel to the frame B to a state perpendicular to the frame B. During the rotation of the temple A, the first connecting body 1 pushes against the mounting plate 32, and during the pushing process, the first connecting body 1 drives the lifting body 31 to rise. At the same time, the lifting body 31 drives each lifting rod 34 to rise. When the first connecting body 1 rotates to be collinear with the second connecting body 2, each leaf spring 33 drives each lifting rod 34 to return to its original position by continuously applying force to each lifting rod 34. The setting of the leaf spring 33 effectively solves the problem of the large space occupied by the installation structure of the compression spring in the prior art. By replacing the compression spring structure with the leaf spring 33 structure, the internal installation space is greatly saved. The structure is ingenious, convenient and practical.
