Description

Technical Field

[0001] This invention relates to the field of magnetic eyeglasses technology, and more particularly to a magnetic eyeglasses system in which the secondary lens is less likely to fall off. Background Technology

[0002] Magnetic eyeglasses typically consist of a main frame and a secondary lens. The main frame has first magnets mounted on posts on both sides, and the secondary lenses have second magnets on both sides corresponding to the first magnets. These magnets hold the secondary lens in place on the front of the main frame, allowing for light filtering depending on the application. However, existing magnetic structures are simple. If one side of the secondary lens is bumped, causing the second magnet to separate from the main frame, the magnet on the other side may be affected by the flipped secondary lens. The edge of the secondary lens on that side can act as a lever, prying the magnet off the main frame, causing the secondary lens to detach completely and potentially damage the lens upon impact. Therefore, designing a magnetic eyeglasses system that prevents the secondary lens from falling off when one magnet separates, thus avoiding the secondary lens affecting the other magnet, is a pressing technical challenge. Summary of the Invention

[0003] To solve the above problems, the present invention provides a magnetic combination eyeglass with a secondary lens that is less likely to fall off.

[0004] The present invention provides a magnetic combination eyeglass with a secondary lens that is not easily dislodged. The eyeglass includes a main frame and a secondary lens. The main frame has posts on both sides for connecting the temples. A first magnet is located on the front of each post. The secondary lens has a second magnet that attracts the first magnet. Each post has a slot for accommodating the first magnet. An elastic hinge is located within the slot. The elastic hinge includes a spring core and a hinge seat. One end of the spring core is connected to the bottom of the slot, and the other end has a hinge joint. The hinge joint is connected to the hinge seat via a pin. The hinge seat is fixed to the back of the first magnet and hinged to the inner wall of the slot. The rotation direction of the hinge seat corresponds to the position of the post on the main frame.

[0005] With the above structure, the first magnet on the front of the lens head attracts the corresponding second magnet on the secondary lens, fixing the secondary lens to the front of the main frame. When one side of the secondary lens is bumped, causing the second magnet to separate forward from the main frame, the second magnet on the other side flips with the secondary lens, pulling the attracted first magnet to flip as well. The first magnet then causes the hinge seat fixed on the back to flip out of the placement slot. The hinge seat is hinged to the inner wall of the placement slot, and the flipping direction corresponds to the position of the lens head on the main frame. The hinge seat on the right side of the lens head flips to the right, and the one on the other side flips to the left, matching the flipping direction of the first magnet. To prevent the secondary lens from separating from the second magnet and keep the magnets on that side attracted to each other, thus preventing complete separation of the secondary lens; by removing the secondary lens and separating the second magnet completely from the first magnet, the hinge joint of the spring core is connected to the hinge seat through a pin. The hinge seat, which has flipped, is pulled by the elastic force of the spring core and flips back to the placement slot for reset; thus, the main frame has a placement slot at the top, and the placement slot is connected to the first magnet at the slot opening by an elastic hinge. When the second magnet on one side of the secondary lens separates from the main frame, the other side can pull the attracted first magnet to flip synchronously, preventing the secondary lens from completely separating from the main frame and avoiding damage upon falling.

[0006] As a further improvement of this utility model, the hinge seat is provided with a pair of hinge pieces, the hinge joint extends between the hinge pieces and leaves a gap, and the pin passes through the hinge piece and is axially connected to the hinge joint.

[0007] With the above structure, the hinge plate is connected to the hinge joint by a pin, which reduces the friction between the hinge seat and the spring core when the elastic hinge is pulled by the first magnet. This makes the glasses rotate smoothly, reduces wear, and extends service life.

[0008] As a further improvement of this utility model, a protective pad is fixed to the inner wall of the placement groove, the protective pad extends to the back of the first magnet, and the protective pad is made of elastic material.

[0009] With the above structure, the hinge seat is pulled back to the placement slot by the spring core to reset, the back of the first magnet abuts against the protective pad to prevent the first magnet from continuing to rotate inward, and the elasticity of the protective pad provides cushioning to prevent the first magnet from breaking.

[0010] As a further improvement of this utility model, the hinge joint has a rounded corner on the side facing the hinge seat.

[0011] With the above structure, the hinge joint has a rounded corner on the side facing the hinge seat. When the elastic hinge rotates, the hinge joint and the hinge seat will not collide, which increases the smoothness of the contact surface between the two and has a good anti-sway effect.

[0012] As a further improvement of this utility model, the front area of ​​the first magnet is larger than the back area of ​​the second magnet.

[0013] With the above structure, since the area of ​​the first magnet is larger than that of the second magnet, even if the magnet on one side of the secondary lens separates, causing the magnet on the other side to slide slightly, it is not easy to separate from the front of the first magnet, and the two remain magnetically attracted to each other.

[0018] like Figures 1-3 The present invention discloses a magnetic combination eyeglasses with a secondary lens that is not easily dislodged, comprising a main frame 1 and a secondary lens 2. The main frame 1 has post 3 for connecting the temples on the left and right sides. The front of the post 3 is provided with a first magnet 4. The secondary lens 2 is provided with a second magnet 5 that is attracted to the first magnet 4. The post 3 is provided with a placement groove 6 for accommodating the first magnet 4. An elastic hinge is provided in the placement groove 6. The elastic hinge includes a spring core 7 and a hinge seat 8. One end of the spring core 7 is connected to the bottom of the placement groove 6, and the other end is provided with a hinge joint 9. The hinge joint 9 is connected to the hinge seat 8 through a pin 10. The hinge seat 8 is fixed to the back of the first magnet 4 and hinged to the inner wall of the placement groove 6. The flipping direction of the hinge seat 8 corresponds to the position of the post 3 on the main frame 1.

[0019] The first magnet 4 on the front of the peg head 3 attracts the corresponding second magnet 5 on the secondary lens 2, fixing the secondary lens 2 to the front of the main frame 1. When one side of the secondary lens 2 is bumped, causing the second magnet 5 to separate forward from the main frame 1, the second magnet 5 on the other side flips with the secondary lens 2, pulling the attracted first magnet 4 to flip as well. The first magnet 4 causes the hinge seat 8 fixed on the back to flip out of the placement groove 6. The hinge seat 8 is hinged to the inner wall of the placement groove 6, and the flipping direction corresponds to the position of the peg head 3 on the main frame 1. The hinge seat 8 on the right side of the peg head 3 flips to the right, and the one on the other side flips to the left, matching the flipping direction of the first magnet 4, to prevent it from interfering with the main frame 1. The second magnet 5 separates, keeping the magnets on that side attracted to each other, preventing the secondary lens 2 from completely separating. After the secondary lens 2 is removed and the second magnet 5 is completely separated from the first magnet 4, the hinge joint 9 of the spring core 7 is connected to the hinge seat 8 through the pin 10. The hinge seat 8, which has flipped, is pulled by the elastic force of the spring core 7 and flips back to the placement slot 6 for reset. This achieves the goal of the main frame 1 having a placement slot 6 on the pile head 3. The placement slot 6 is connected to the first magnet 4 at the slot opening by an elastic hinge. When the second magnet 5 on one side of the secondary lens 2 separates from the main frame 1, the other side can pull the attracted first magnet 4 to flip synchronously, preventing the secondary lens 2 from completely separating from the main frame 1 and avoiding damage from falling to the ground.

[0020] The hinge seat 8 is provided with a pair of hinge pieces 11, the hinge joint 9 extends between the hinge pieces 11 and leaves a gap, and the pin 10 passes through the hinge pieces 11 and is axially connected to the hinge joint 9.

[0021] By connecting the hinge plate 11 and the hinge joint 9 through the pin 10, the friction between the hinge seat 8 and the spring core 7 is reduced when the elastic hinge is pulled by the first magnet 4, so that the glasses can rotate smoothly, with less wear and a longer service life.

[0022] A protective pad 12 is fixed to the inner wall of the placement groove 6. The protective pad 12 extends to the back of the first magnet 4 and is made of elastic material.

[0023] The hinge seat 8 is pulled back to the placement slot 6 by the spring core 7 to reset. The back of the first magnet 4 abuts against the protective pad 12, preventing the first magnet 4 from continuing to rotate inward. The elasticity of the protective pad 12 provides cushioning to prevent the first magnet 4 from breaking.

[0024] The hinge joint 9 has a rounded corner on the side facing the hinge seat 8.

[0025] With the hinge joint 9 having a rounded corner on the side facing the hinge seat 8, the hinge joint 9 and the hinge seat 8 will not collide when the elastic hinge rotates, increasing the smoothness of the contact surface between the two and providing good anti-sway effect.

[0026] The front area of ​​the first magnet 4 is larger than the back area of ​​the second magnet 5.

[0027] Since the area of ​​the first magnet 4 is larger than that of the second magnet 5, even if the magnet on one side of the secondary lens 2 separates, causing the magnet on the other side to slide slightly, it is not easy to separate from the front of the first magnet 4, thus maintaining their mutual magnetic attraction.
