Description

Technical Field

[0001] This invention relates to the field of eyeglasses technology, and more particularly to a temple connection structure and eyeglasses. Background Technology

[0002] Currently, eyeglass temples are typically connected to the frame using hinges. When the temples are pulled outwards under stress, they can deform and break, and the size is difficult to adjust, significantly impacting user comfort and durability. While changing the material of the frame or temples to use more flexible materials can accommodate users with different face widths, this increases the cost of the glasses. Furthermore, typical eyeglasses suffer from problems such as difficulty in removing and installing temples, the inability to replace temples individually, or the need for tools for disassembly and installation, making temple replacement and repair inconvenient.

[0003] Therefore, it is necessary to provide a new temple connection structure and eyeglasses to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a temple connection structure and eyeglasses, which enables quick installation and removal of the temples while ensuring comfort and stability during use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] As a further improved technical solution of the present invention, the third end also includes a first limiting part, and the round head is adapted to the first limiting part.

[0012] As a further improvement of the present invention, the mating part further includes a third limiting part, which is located on the side of the snap-fit ​​groove away from the first fixing part, and the height of the third limiting part is lower than the height of the first fixing part and lower than the height of the second limiting part.

[0013] As a further improved technical solution of the present invention, the snap-fit ​​groove has a first surface, a second surface and a third surface, and the fourth end also includes a first connection portion and a second connection portion;

[0014] The first connecting part is connected to the first surface, the second connecting part is connected to the second surface, and the second limiting part is connected to the third surface.

[0015] As a further improvement of the present invention, a sliding part is further included between the main body and the first end, and the sliding part is adapted to the slide rail.

[0016] As a further improvement of the present invention, the sliding part has a first sliding surface and a second sliding surface, the first sliding surface being adapted to the circular shaft part, and the second sliding surface being adapted to the groove surface of the arc-shaped groove.

[0017] As a further improved technical solution of the present invention, a first transition portion is provided between the first fixing portion and the arc-shaped groove, and a second transition portion is provided between the second fixing portion and the third end portion.

[0024] Compared to existing technologies, the beneficial effects of the temple connection structure and eyeglasses of this invention are as follows: By setting an mounting part on the temple and a fitting part on the frame, and setting a spring piece inside the fitting part to connect the mounting part and the fitting part, a simple structure is used to achieve a movable connection between the temple and the frame. When eyeglasses using this temple connection structure are in an outward-expanding state, applying an outward force to the temple will cause it to detach from the frame, enabling quick installation and removal of the temple, thus facilitating style changes and repairs. When worn by users with narrow faces, the spring piece applies a certain force to keep the temple close to the face; when worn by users with wide faces, the spring piece deforms under force and also rebounds, allowing the temple to both expand outwards and remain close to the face at all times, thus adapting to users with different face widths while ensuring user comfort and stability.

[0051] Please see Figures 3 to 5As shown, the mating part 10 includes an arc-shaped groove 11, a snap-fit ​​groove 12, a first fixing part 13, and a third limiting part 14. The first fixing part 13 is located between the arc-shaped groove 11 and the snap-fit ​​groove 12 along the L direction and protrudes relative to the arc-shaped groove 11 and the snap-fit ​​groove 12. The first fixing part 13 is provided with at least one first fixing hole 131. Specifically, in this embodiment, the first fixing part 13 is provided with two first fixing holes 131 along the W direction. Moreover, the first fixing part 13 is formed as an inclined surface in the L direction, and its height decreases from one end near the arc-shaped groove 11 to the other end. The third limiting part 14 is located on the side of the snap-fit ​​groove 12 away from the first fixing part 13, that is, the third limiting part 14 is located on the side of the snap-fit ​​groove 12 in the L direction relative to the first fixing part. On the other side of 13, further, in the H direction, the height of the third limiting part 14 is lower than the height of the first fixing part 13; in the L direction, one end of the snap-fit ​​groove 12 is slotted from the middle of the first fixing part 13, and the other end extends to the third limiting part 14.

The space formed by this distance is connected to the snap-fit ​​groove 12.

[0052] In other embodiments, the protruding portions of the snap-fit ​​groove 12 along both sides in the W direction are connected to the third limiting portion 14, so that the snap-fit ​​groove 12 is completely enveloped in the L and W directions; or, the first fixing portion 13 is square, and in the L direction, the snap-fit ​​groove 12 extends from the side of the first fixing portion 13 away from the arc-shaped groove 11 to the third limiting portion 14, and the first fixing portion 13 is not connected to the third limiting portion 14, and the space between the first fixing portion 13 and the third limiting portion 14 forms an elongated groove, which can be partially or entirely used as the snap-fit ​​groove 12.

[0053] Furthermore, the snap-fit ​​groove 12 has a first surface 121, a second surface 122 and a third surface 123, wherein the first surface 121 is formed by the side of the first fixing part 13 that protrudes relative to the snap-fit ​​groove 12, the third surface 123 is formed by the side of the third limiting part 14 that protrudes relative to the snap-fit ​​groove 12, and the second surface 122 connects the lowest point of the first surface 121 and the third surface 123.

[0054] Furthermore, the mating part 10 also has an arc-shaped segment 16, from Figure 4 and Figure 5 As can be seen, the arc groove 11, the snap-fit ​​groove 12, the first fixing part 13 and the third limiting part 14 are all located inside the groove of the mating part 10 as a whole, while the arc segment 16 is located outside the groove, and the arc segment 16 is located on the side of the third limiting part 14 away from the arc groove 11 in the L direction.

[0055] Please see Figures 6 to 8As shown, the mounting part 20 has a first wall surface 201 and a second wall surface 202. The mounting part 20 includes a main body 21 and a first end 22 and a second end 23 located at both ends of the main body 21 in the L direction. The first end 22 and the second end 23 are both formed toward the first wall surface 201. The second wall surface 202 is formed as a flat surface. A sliding part 24 is also included between the main body 21 and the first end 22. The sliding part 24 has a first sliding surface 241 and a second sliding surface 242, wherein the first sliding surface 241 is in contact with the first wall surface 201 and the second sliding surface 242 is in contact with the second wall surface 202; the first end part 22 includes a round head 221 and a first recess 222, the first recess 222 is in contact with the second sliding surface 242, and the first recess 222 is recessed inward relative to the round head 211 and the second sliding surface 242; in the L direction, the main body part 21 is provided with a second recess 211, the second recess 211 is in contact with the second end part 23, and the second recess 211 is recessed inward relative to the main body part 211 and the second end part 23; the second end part 23 is inclined, and its height in the H direction increases from the side closer to the main body part 21 to the other side.

[0056] In other embodiments, the first end portion 22 may not have the first recess 222, and the round head 221 and the second smooth surface 242 form a complete arc surface; the second end portion 23 may also have other shapes, and the height of each position in the H direction may be equal or decrease from one side closer to the main body portion 21 to the other side.

[0057] Please see Figures 9 to 11 As shown, the spring piece 30 includes a second fixing part 31 and a third end 32 and a fourth end 33 disposed at both ends of the second fixing part 31 in the L direction. The second fixing part 31 is straight and has at least one second fixing hole 311. Specifically, in this embodiment, the second fixing part 31 has two second fixing holes 311. The third end 32 includes a round shaft part 321 and a first limiting part 322. The round shaft part 321 is approximately a complete circle, and the first limiting part 322 connects the round shaft part 321 and the second fixing part 31. The fourth end 33 includes a second limiting part 331, a first connecting part 332 and a second connecting part 333. The second limiting part 331, the second connecting part 333, the first connecting part 332, and the second fixing part 31 are all connected together. Specifically, the first connection 332 extends downward in the H direction from the middle of the second fixing part 31. Further, the first connection 332 extends downward between the two second fixing holes 311. The second connection 333 extends in the L direction away from the end of the first connection 332 away from the second fixing part 31, and the second limiting part 331 extends upward in the H direction from the end of the second connection 333 away from the first connection 332. In this embodiment, the second fixing part 31 is concave, and the concave middle part forms the fourth end 33.

[0058] In other embodiments, the second fixing portion 31 is square, and in the L direction, the first connecting portion 332 extends from the side of the second fixing portion 31 away from the third end portion 32. The width of the fourth end portion 33 in the W direction is less than or equal to the width of the second fixing portion 31. Specifically, the widths of the second limiting portion 331, the first connecting portion 332, and the second connecting portion 333 may be equal or unequal. For example, the widths of the second limiting portion 331, the first connecting portion 332, and the second connecting portion 333 may be equal and less than the width of the second fixing portion 31, or the widths of the second limiting portion 331, the first connecting portion 332, and the second connecting portion 333 may be equal and equal to the width of the second fixing portion 31, or the width of the second limiting portion 331 may be less than the widths of the first connecting portion 332, the second connecting portion 333, and the second fixing portion 31. This is not limited to the cases listed above, and other unlisted cases within the scope of this embodiment are also applicable.

[0059] Please see Figure 12 As shown, the temple connection structure also includes a fixing member 40. In this embodiment, the fixing member 40 is a screw. The fixing member 40 includes a column head 41 and a column body 42. The column body 42 is provided with external threads. The column head 41 is fixed to one end of the column body 42, and the side of the column head 41 away from the column body 42 is provided with a groove 411. Specifically, the groove 411 is cross-shaped and is used to allow a screwdriver to rotate the fixing member 40. Further, the connection between the column head 41 and the column body 42 is a uniformly transitioning cone shape, and the diameter of the column head 41 increases from the end connected to the column body 42 to the other end.

[0060] Please see Figure 13 As shown, the spring piece 30 is fixedly installed in the mating part 10, the second fixing part 31 is attached to the first fixing part 13 and the fourth end 33 is locked in the snap-fit ​​groove 12, the fixing member 40 is inserted into the second fixing hole 311 and the first fixing hole 131 in sequence and tightened, and the third end 32 is suspended in the arc groove 11; the first connecting part 332 is connected to the first surface 121, the second connecting part 333 is connected to the second surface 333, and the second limiting part 331 is connected to the third surface 123. Further, the first connecting part 332 is attached to the first surface 121, the second connecting part 333 is attached to the second surface 122, and the second limiting part 331 is attached to the third surface 123 in a natural state, that is, in a state without being squeezed. Specifically, in the W direction, the width of the third end 32 is less than or equal to the width of the second fixing part 31, the width of the second fixing part 31 is less than or equal to the width of the first fixing part 13, and in this embodiment, the width of the second fixing part 31 is slightly less than the width of the first fixing part 13, and the width of the third end 32 is less than the width of the second fixing part 31.

[0061] Please see Figure 14 and Figure 15As shown, after the spring piece 30 is installed in the mating part 10, the third end 32 extends into the arc-shaped groove 11 and cooperates with the arc-shaped groove 11 to form a slide 101. The first end 22 is slidably installed in the slide 101, and the size of the round head 221 is equivalent to that of the slide 101. A first transition part 15 is also provided between the first fixing part 13 and the arc-shaped groove 11, and a second transition part 34 is also provided between the second fixing part 31 and the third end 32. The first transition part 15 and the second transition part 34 are adapted to each other and are elastically connected. In a natural state, i.e., without compression, the second transition part 34 is partially connected to the first transition part 15. The mounting part 20 is detachably installed in the mating part 10.

[0062] Based on the above embodiment, the height of the third limiting part 14 is lower than the height of the second limiting part 331, and the second end 23 can elastically abut against the second limiting part 331, so that the second limiting part 331 can be compressed and generate a rebound. The sliding part 24 is adapted to the slide rail 101. Specifically, the first sliding surface 241 is adapted to the round shaft part 321, and the second sliding surface 242 is adapted to the groove surface of the arc groove 11, so that the sliding part 24 can rotate in coordination with the entire mounting part 20.

[0063] Considering the overall fit, ease of processing, cost, and aesthetics of the temple connection structure, in the mounting part 20, the width of the first end 22 in the W direction is smaller than the width of the main body 21 in the W direction. In the spring piece 30, the width of the third end 32 in the W direction is smaller than the width of the second fixing part 31 in the W direction. The width of the first end 22 is equivalent to the width of the third end 32, and when they are installed in the mating part 10, they are located on the same side in the W direction.

[0064] Please see Figure 16 and Figure 17As shown, in the first state, the temple 2 and the head 5 are connected in a straight line. When the mounting part 20 is installed on the mating part 10, the round head 221 is squeezed into the slide 101. During the process of the round head entering, the third end 32 is squeezed downward. The third end 32 retracts downward and drives the second transition part 34 to move toward the first transition part 15, thereby increasing the contact area between the second transition part 34 and the first transition part 15, thus providing space for the entry of the first end 22. After assembly, the third end 32 and the second transition part 34 spring back to cooperate with the mounting part 20. At this time, the second recessed part 211 and the second fixing part 31 are in corresponding positions and the space between them is large. The first sliding surface 241 is slidably connected to the round shaft part 321, and the second sliding surface 242 is slidably connected to the groove surface of the arc groove 11. All parts of the first sliding surface 241 are in contact with the round shaft part 321, and the second sliding surface 242 is only partially in contact with the groove surface of the arc groove 11. The end of the second end 23 near the first end 22 abuts against the second limiting part 331. The second limiting part 331 generates a certain rebound force on the second end 23, causing the mounting part 20 to drive the temple 2 to retract inward as a whole. When worn by users with smaller face widths, the temple 2 can fit snugly against the face, providing good comfort and stability.

[0065] Please see Figure 18 and Figure 19 As shown, in the second state, the temple 2 is in a retracted state. During the process of changing from the used state to the retracted state, the mounting part 20 and the temple 2 as a whole rotate around the circular shaft part 321. The round head 221 slides in the slide rail 101. The first sliding surface 241 slides along the outer surface of the circular shaft part 321, and the second sliding surface 242 slides along the groove surface of the arc-shaped groove 11. All parts of the first sliding surface 241 are connected to the circular shaft part 321, and all parts of the second sliding surface 242 are connected to the groove surface of the arc-shaped groove 11. The second end 23 begins to move away from the second limiting part 331, and the second limiting part 331 is attached to the third surface 123. When the round head 221 abuts against the first limiting part 322, the rotation stops. At this time, the first end 22 exerts a certain upward squeezing force on the third end 32, and drives the second transition part 34 to move upward, so that the contact area between the second transition part 34 and the first transition part 15 is reduced. The third end 32 and the second transition part 34 rebound downward to prevent the temple 2 from being over-retracted.

[0066] Please see Figure 20 and Figure 21As shown, in the third state, the temple 2 is in an outward-expanding state. The second end 23 presses downward against the second limiting part 331, causing the second limiting part 331 to deform under force. The end of the second limiting part 331 connected to the second connecting part 333 is fixed, and the end of the second limiting part 331 in contact with the second end 23 causes the whole to tilt towards the second connecting part 333. The space between the second recess 211 and the second fixing part 31 is reduced, the contact area between the second sliding surface 242 and the groove surface of the arc groove 11 is reduced, and the round head 221 exerts upward pressure on the third end 32 and the second transition part 34. The contact area between the second transition part 34 and the first transition part 15 is reduced. At this time, the second limiting part 331 generates a rebound force on the second end 23, and the third end 32 and the second transition part 34 generate a downward rebound force, thereby causing the mounting part 20 to drive the temple 2 to retract inward. When worn by users with wider faces, the temple 2 can fit snugly against the face, providing good comfort and stability. When the end of the second end 23 away from the second recess 211 abuts against the third limiting part 14, it is in the most outwardly expanded state. In this state, when the temple 2 is pressed outward with force, the end face of the temple 2 with the mounting part 20 contacts the arc segment 16. The arc segment 16 provides it with outward expansion space, and the third end 32 of the spring piece 30 retracts downward, so that the mounting part 20 slides out of the mating part 10 as a whole, and the temple 2 can be removed.

[0067] In some embodiments, the spring 30 is made of a metal material with good elasticity, which is simple to manufacture and has low cost. The mounting part 20 is made of a smooth material with a low coefficient of friction, which makes it easy to slide in the slide rail 101.

[0068] In some embodiments, the connection of the diameters of the various parts of the mounting part 20, the connection between the various parts of the mating part 10, and the connection between the various parts of the spring piece 30 are all made with a gentler rounded corner transition to prevent the formation of sharp corners between the various parts from causing damage to the various parts or to the user.

[0069] Furthermore, the second limiting portion 331 is also provided with a bent portion 3311 at one end near the second end portion 23. The bent portion 3311 extends toward the first connecting portion 332, and the connection between the bent portion 3311 and the second limiting portion 331 is rounded to prevent the second limiting portion 331 from damaging the second end portion 23 when the second end portion 23 squeezes the second limiting portion 331. In other embodiments, the end of the second limiting portion 331 near the second end portion 23 can also be provided as a gentle curved surface or other shapes to protect the second end portion 23.

[0070] In summary, compared with the prior art, the temple connection structure and eyeglasses of the present invention have the following advantages: By providing an mounting part 20 on the temple 2 and a fitting part 10 on the frame 1, and by providing a spring piece 30 within the fitting part 10 to connect the mounting part 20 and the fitting part 10, a simple structure is used to achieve a movable connection between the temple 2 and the frame 1. When eyeglasses using this temple connection structure are in an outward-expanding state, applying an outward force to the temple 2 will cause the temple 2 to detach from the frame 1, enabling quick installation and removal of the temple 2, thus facilitating style changes and repairs. When worn by users with narrow faces, the spring piece 30 applies a certain force to keep the temple 2 close to the face; when worn by users with wide faces, the spring piece 30 deforms under force and also produces a certain amount of rebound, allowing the temple 2 to both expand outward and remain close to the face at all times, thus adapting to users with different face widths while ensuring user comfort and stability.
