Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses, specifically relating to a dual-axis rotation mechanism; it also relates to eyeglasses using the dual-axis rotation mechanism. Background Technology

[0002] Currently, existing eyeglasses generally include a frame, temples, a hinge connecting the frame and temples, and lenses mounted on the frame. The temples are opened or folded relative to the frame by rotating the hinge.

[0003] Then, in actual use, existing glasses, in order to adapt to users with different face shapes, mainly use hinges consisting of a single axis and elastic elements. During the temple flipping process, the elastic element deforms to form an elastic clamping force, which is prone to the following defects:

[0004] 1. During the process of unfolding the temples, it is necessary to overcome the reverse elastic force generated by the deformation of the elastic element, which not only easily causes the temples to deform and affects their service life, but also results in poor handling.

[0005] 2. In order to meet the rotation space requirements of the hinge, a large space needs to be reserved between the temple and the frame, which results in a loose structure, poor stability, and easy user error that causes the temple to unfold beyond the reasonable angle, increasing the probability of damage to the glasses. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved dual-axis rotation mechanism.

[0007] In addition, this utility model also provides a pair of eyeglasses.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A dual-axis rotation mechanism includes a base and a flipping seat. The flipping seat includes a first seat body rotatably connected to the base via a first pivot and a second seat body rotatably connected to the first seat body via a second pivot. The first and second pivots are arranged side by side and spaced apart. The first seat body has a first state in which it can freely rotate relative to the base and a second state in which it abuts against the base. The dual-axis rotation mechanism also includes an elastic element connected between the first seat body and the second seat body. When the first seat body is in the first state, the first seat body and the second seat body rotate synchronously around the first pivot. When the first seat body is in the second state, the second seat body rotates around the second pivot and drives the elastic element to deform to form gradually increasing or decreasing damping.

[0010] According to a specific embodiment and preferred aspect of this utility model, a first abutment and a second abutment are correspondingly formed on a first base and a second base, wherein the first abutment and the second abutment are circumferentially spaced around a second pivot, and an elastic member abuts between the first abutment and the second abutment. When the first base is in a second state, the first abutment abuts against the base. Here, when the first base is in the second state, the first and second abutment are precisely aligned and cooperate in the circumferential direction of the second pivot to drive the elastic member to form damping.

[0011] Preferably, the first and second contact portions are respectively formed into a first column and a second column from opposite sides. The elastic element is a spring, which is respectively sleeved on the first and second columns from both ends. When the first seat is in the first state, the center lines of the first and second columns coincide. Here, the radial deformation of the spring is reduced during the flipping movement of the first seat, extending its service life. At the same time, the structure is simple and easy to install and implement.

[0012] Specifically, the first column, the second column, and the elastic element constitute a damping group, and there are at least two damping groups distributed at axial intervals along the second pivot. Here, uniform damping distribution is ensured to improve the user experience.

[0013] According to another specific embodiment and preferred aspect of this utility model, the first seat body also has an outwardly protruding limiting portion, and the second seat body has a movable portion. When the first seat body is in the first state, the second seat body abuts against the limiting portion from the movable portion based on the elastic force formed by the elastic member. Here, the stability of the second seat body is ensured during the flipping movement of the first seat body.

[0014] Preferably, an arc-shaped guide surface is formed on the first seat body, which is located between the limiting part and the first contact part and extends circumferentially around the second pivot. When the first seat body is in the second state, the movable part fits against the guide surface and moves around the center line of the second pivot.

[0015] According to another specific embodiment and preferred aspect of the present invention, the first base has a first connecting end and a second connecting end that are rotatably connected to the first and second pivots, and the second base has a third connecting end that is rotatably connected to the second pivot, wherein at least one insertion groove is formed on the second connecting end, and the third connecting end is inserted into the insertion groove.

[0016] Preferably, the base includes a base body and a connecting module fixedly mounted on the base body. A plurality of insertion slots are formed on the first connecting end, spaced apart along the first pivot axis. A plurality of connecting ears are formed on the connecting module, corresponding to each insertion slot. This enhances the connection stability between the base and the first and second base bodies, prevents axial displacement along the pivot axis, and improves the rotational feel.

[0017] Another technical solution of this utility model is a pair of eyeglasses, which includes a base, temples and lenses. The eyeglasses also include the above-mentioned dual-axis rotation mechanism, wherein the base is fixedly connected to the base and the temples are fixedly connected to the second base body.

[0018] In addition, the temple has an unfolded state and a folded state, wherein when the temple switches between the folded state and the unfolded state, the first seat body rotates around the first pivot between the first state and the second state, and the rotation angle is 0 to 90°; and / or, based on the first seat body being in the second state, the temple and the second seat body rotate outward around the second pivot angle of 0 to 10°.

[0019] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] Existing eyeglasses require overcoming the reverse elastic force generated by the deformation of elastic components during the unfolding of the temples. This not only easily causes deformation of the temples, affecting their lifespan, but also results in poor handling. At the same time, in order to meet the rotation space requirements of the hinges, a large space needs to be reserved between the temples and the frame, resulting in a loose structure, poor stability, and easy user error that causes the temples to unfold beyond the reasonable angle, increasing the probability of damage to the eyeglasses. This application presents an overall design for the dual-axis rotation mechanism, cleverly addressing the shortcomings and defects of existing technologies. By adopting this dual-axis rotation mechanism, the frame of the glasses is fixedly connected to the base, and the temples are fixedly connected to the second base. The first base is in a first state and can freely rotate relative to the base, while the second base rotates synchronously around the first pivot, thus enabling the temples to unfold or fold without damping relative to the frame. Then, the first base rests against the base in a second state, limiting the rotation angle. The second base then rotates around the second pivot, causing the elastic element to deform and gradually increase or decrease damping, allowing for adaptive adjustment of the temples' damping to accommodate different face widths. Therefore, compared with the prior art, this utility model has two advantages. First, it is based on a dual-axis layout, which effectively saves the space required for flipping and has a compact structure, which is conducive to improving the connection stability between the temple and the base. Second, based on the cooperation of the first and second bases, the temple can be freely flipped open or folded. Furthermore, the damping magnitude can be adjusted by the movement of the second base under the limit of the first base, which effectively reduces the probability of temple deformation and damage and extends the service life.

[0034] like Figures 1 to 6 As shown, the eyeglasses in this embodiment include a base ①, temples ②, lenses, and a dual-axis rotation mechanism ③.

[0035] In this embodiment, there are two dual-axis rotation mechanisms ③, which are respectively connected between the opposite sides of the lens base ① and the corresponding temple ②. The following description focuses on one side of the dual-axis rotation mechanism ③, while the other structure is also clear.

[0036] The dual-axis rotation mechanism ③ includes a base 1, a flip seat 2, and an elastic element 3, wherein the base 1 is fixedly connected to the mirror base ①; the flip seat 2 includes a first seat body 21 rotatably connected to the base 1 via a first pivot s 1, and a second seat body 22 rotatably connected to the first seat body 21 via a second pivot s 2, wherein the first pivot s 1 and the second pivot s 2 are arranged side by side and spaced apart, and the temple ② is fixedly connected to the second seat body 22.

[0037] In this example, the base 1 includes a base body 10 and a connecting module 11 fixedly mounted on the base body 10. A first pivot s 1 is mounted on the connecting module 11. The first base body 21 has a first connecting end d1 and a second connecting end d2 that are rotatably connected to the first pivot s 1 and the second pivot s 2, respectively. The second base body 22 has a third connecting end d3 that is rotatably connected to the second pivot s 2 and a fourth connecting end d4 that is fixedly connected to the temple ②.

[0038] For ease of implementation, two insertion slots c are formed on the first connecting end d1, spaced apart along the axial direction of the first pivot s1. Two connecting ears 110 are formed on the connecting module 11, corresponding to each insertion slot c. The first pivot s1 passes through the two insertion slots c and the connecting ears 110. Simultaneously, at least one insertion slot c is formed on the second connecting end d2, and the third connecting end d3 is inserted into one of the insertion slots c. The second pivot s2 passes through the third connecting end d3 and the insertion slot c. This enhances the connection stability between the base and the first and second base bodies, prevents axial displacement along the pivot, and improves the rotational feel.

[0039] In this example, the elastic element 3 is connected between the first seat 21 and the second seat 22. That is, the first seat 21 of this application has a first state in which it can freely rotate relative to the base 1, and a second state in which it abuts against the base 1. When the first seat 21 is in the first state, the first seat 21 and the second seat 22 rotate synchronously around the first pivot s1. When the first seat 21 is in the second state, the second seat 22 rotates around the second pivot s2 and drives the elastic element 3 to deform to form gradually increasing or decreasing damping. At the same time, when the temple ② switches between the folded state and the unfolded state, the first seat 21 rotates around the first pivot s1 between the first state and the second state, and the rotation angle is 0 to 90°. Based on the first seat 21 being in the second state, the temple ② and the second seat 22 rotate outward around the second pivot s2 by an angle of 0 to 10°.

[0040] In some specific embodiments, a first abutment portion 210 and a second abutment portion 220 are correspondingly formed on the first seat 21 and the second seat 22, located on the second connecting end d2 and the third connecting end d3, respectively. The first abutment portion 210 and the second abutment portion 220 are circumferentially spaced around the second pivot s2. The elastic member 3 abuts between the first abutment portion 210 and the second abutment portion 220. When the first seat 21 is in the second state, the first abutment portion 210 abuts against the base 1. Here, when the first seat 21 is in the second state, the first and second abutment portions are precisely aligned and cooperate in the circumferential direction of the second pivot s2 to drive the elastic member 3 to form damping.

[0041] To further facilitate implementation, the first contact portion 210 and the second contact portion 220 are respectively formed from opposite side surfaces to form a first column z1 and a second column z2. The elastic element 3 is a spring and is respectively sleeved on the first column z1 and the second column z2 from both ends. When the first seat 21 is in the first state, the center lines of the first column z1 and the second column z2 remain coincident. Here, the deformation of the spring in the radial direction is reduced during the flipping movement of the first seat, extending its service life. At the same time, the structure is simple and easy to install and implement.

[0042] Specifically, the first column z1, the second column z2, and the elastic element 3 constitute a damping group, and there are at least two damping groups distributed at intervals along the axial direction of the second pivot s2. This ensures uniform damping distribution and improves the user experience. In some other embodiments, the elastic element 3 may also be a spring sheet.

[0043] Meanwhile, outwardly protruding limiting portions 211 are formed on opposite sides of the second connecting end d2 on the first seat 21, and movable portions 221 are formed on opposite sides of the fourth connecting end d4 on the second seat 22. The limiting portions 211 are located on the rotation path of the movable portions 221 around the second pivot s2, and when the first seat 21 is in the first state, the second seat 22 abuts against the limiting portions 211 from the movable portions 221 based on the elastic force formed by the elastic member 3. Here, the stability of the second seat is ensured during the flipping movement of the first seat.

[0044] Furthermore, the first seat 21 has an arcuate guide surface m formed at the edge of the second connecting end d2, which is located between the limiting part 211 and the first contact part 210 and extends circumferentially around the second pivot s2. When the first seat 21 is in the second state, the movable part 221 fits against the guide surface m and moves around the center line of the second pivot s2.

[0045] In summary, by adopting this dual-axis rotation mechanism, the frame of the glasses is fixedly connected to the base, and the temples are fixedly connected to the second base. The first base is in a first state and can rotate freely relative to the base, while the second base rotates synchronously around the first pivot, thereby realizing the undamped unfolding or folding movement of the temples relative to the frame. Then, the first base rests against the base and is in a second state, which limits the rotation angle. The second base rotates around the second pivot and drives the elastic element to deform, thereby creating gradually increasing or decreasing damping, achieving adaptive adjustment of the temples' clamping damping for users with different face widths. Therefore, compared with the prior art, this utility model has the following advantages: First, based on the dual-axis layout, it effectively saves the space required for flipping, has a compact structure, and is conducive to improving the connection stability between the temple and the base. Second, based on the cooperation of the first and second bases, it enables the temple to be freely flipped open or folded, and the damping magnitude can be adjusted by the movement of the second base under the restraint of the first base, effectively reducing the probability of temple deformation and damage and extending service life. Third, when the first base is in the second state, the first and second contact parts are precisely aligned and cooperated in the circumferential direction of the second pivot to drive the elastic element to form damping. Fourth, it enhances the connection stability between the base and the first and second bases, avoids offset in the pivot axis, and improves the rotational feel.

[0046] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
