[0002] There are often certain shape differences in the head shapes of users. The same style of glasses from sports glasses manufacturers needs to face users with round skull shapes and long skull shapes at the same time. Therefore, glasses manufacturers currently need to develop different head circumference glasses sizes specifically to meet the wearing requirements of users, and the development cost and cycle are relatively large.

[0003] To avoid sports injuries caused by the loosening of sports glasses from the wearing position during use, the current solutions usually tend to achieve a firm wearing purpose by improving the clamping force of the temples through structural design.

[0004] The prior art discloses a bendable elastic glasses, whose authorized announcement number is CN204536672U, and the authorized announcement date is August 5, 2015. It includes: a glasses frame, a first temple, a second temple, a first elastic connecting member and a second elastic connecting member. The first temple is detachably connected to one end of the glasses frame through the first elastic connecting member, and the first temple is arranged inside the glasses frame. The second temple is detachably connected to the other end of the glasses frame through the second elastic connecting member, and the second temple is arranged inside the glasses frame. This solution has the functions of being easy to disassemble and bendable outward. From the content of this solution, it can be seen that it controls the firmness of wearing through the elasticity of the elastic connecting member.

[0005] Taking the above prior art as an example, the existing solutions have led to a reduction in wearing comfort and may cause damage to the wearing position. Products that achieve a firm wearing by increasing the clamping force of the temples will cause varying degrees of deformation of the product lenses, resulting in other adverse symptoms such as dizziness and blurring for users, affecting the use experience. Summary of the Invention

[0006] The purpose of the present invention is to provide an elastic temple structure composed of magnetic materials, which overcomes the problems of temple clamping force, wearing firmness, wearing comfort, and small application range existing in existing sports glasses products.

[0007] The purpose of the present invention is achieved in this way: an elastic temple structure composed of magnetic materials, including a lens connection part and a movable part rotatably connecting the lens connection part. The movable part contacts the head and is driven by the contact force to perform left and right deflection activities. At least one magnetic part is installed on both the lens connection part and the movable part. The magnetic parts on the lens connection part and the movable part are opposite in the same pole to form a repulsive force to control the movement stroke and / or movement torque of the movable part.

[0008] Further, the magnetic members of the lens connecting portion and the movable portion are a first magnetic block and a second magnetic block respectively.

[0009] Further, the first magnetic block and the second magnetic block are respectively fixedly inserted into the lens connecting portion and the movable portion.

[0010] Further, the installation position of the magnetic member is forward relative to the rotation fulcrum of the movable portion.

[0011] Further, the outer side surface of the lens connecting portion is set as a concave surface, and the concave surface has a slot for installing the magnetic member of the lens connecting portion.

[0012] Further, the movable portion has a front extension portion extending forward based on its fulcrum and facing the concave surface, and a magnetic member is fixedly installed on the front extension portion.

[0013] Further, a movable fulcrum plate is fixed to the rear end of the lens connecting portion, and the movable portion is rotatably connected to the movable fulcrum plate of the lens connecting portion.

[0014] Further, the movable fulcrum plate is located at the outer side of the rear end of the lens connecting portion and is set as the rotation fulcrum of the movable portion.

[0015] Further, the length of the movable portion is greater than the length of the lens connecting portion.

[0016] Further, the movable portion is set as a bent rod that bends inward, and a flexible contact member in contact with the skull is attached to the inner side or both the inner and outer sides thereof.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. By providing a movable portion containing a magnetic material and a lens connecting portion containing a magnetic material, using the repulsive force formed by the like poles of the magnetic member of the movable portion and the magnetic member of the lens connecting portion facing each other, during the wearing process, the movement stroke and / or movement torque of the movable portion can be controlled. While keeping the deformation of the product lens small, it can be compatible with users with round skulls and long skulls, and can be compatible with different head circumferences. After taking off the glasses, the temple can return to its original state;

[0019] 2. By providing a magnetic material, the movement range of the temple is larger, and it can meet different exercise scenarios of the crowd;

[0020] 3. Through the movable structure designed by the repulsive force of the magnetic material, when the temple is stressed, the movable portion performs a rotational movement, effectively preventing the deformation of the lens;

[0021] 4. By providing a movable structure composed of a magnetic material, the manufacturing and complex structure of the original telescopic elastic scheme can be greatly simplified;

[0022] 5. By using flexible contacts in combination, the probability of the glasses being displaced from the usage position due to intense movement can be reduced under the premise of a relatively light clamping force. Brief Description of the Drawings

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the attached Figures 1-4 drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] As Figures 1-3 shown, an elastic temple structure composed of magnetic materials is proposed, and the main concept is as follows:

[0030] It includes a lens connecting part 1 and a movable part 2 rotatably connected to the lens connecting part 1. The movable part 2 contacts the head and is driven by the contact force to deflect left and right. At least one magnetic member is installed on both the lens connecting part 1 and the movable part 2. The magnetic members of the lens connecting part 1 and the movable part 2 are opposite in the same pole and are directly opposite to each other in position to form a repulsive force to control the movement stroke and / or movement torque of the movable part 2.

[0031] When the temple structure is in use, the movable part 2 contacts the head of the user, causing the movable part 2 to rotate a certain angle around the hinge of the lens connecting part 1, and the movement stroke of the movable part 2 is controlled by the repulsive force of two magnetic materials with the same polarity facing each other.

[0032] As a preferred embodiment, there are various choices for the structural forms of the magnetic members of the lens connecting part 1 and the movable part 2. In this embodiment, they are the first magnet 3 and the second magnet 4 respectively, and also include the selection of electromagnets or other magnetic materials.

[0033] As an optional installation solution, the above-mentioned first magnetic block 3 and second magnetic block 4 are respectively fixedly inserted into the lens connecting part 1 and the movable part 2.

[0034] As Figure 1 , 4 shown, the installation position of the above-mentioned magnetic part is forward relative to the rotation fulcrum of the movable part 2. The outer side surface of the lens connecting part 1 is set as a concave surface 1b, and the concave surface 1b has a slot 5 for installing the magnetic part of the lens connecting part 1. The movable part 2 has a front extension part extending forward based on its fulcrum and facing the concave surface 1b, and a slot 5 is also provided on the inner side of the front extension part to fixedly install the magnetic part.

[0035] A movable fulcrum plate 1a is fixedly installed at the rear end of the above-mentioned lens connecting part 1, and the movable part 2 is rotationally connected to the movable fulcrum plate 1a of the lens connecting part 1. Moreover, the above-mentioned movable fulcrum plate 1a is located at the outer side of the rear end of the lens connecting part 1 and is set as the rotation fulcrum of the movable part 2.

[0036] As a preferred rotational connection solution for the movable part 2, a movable fitting hole 2a is provided at the position of the movable part 2 facing the movable fulcrum plate 1a. The movable fulcrum plate 1a is movably fitted with the movable fitting hole 2a, and the rotating shaft of the movable fulcrum plate 1a is arranged at the position of the movable fitting hole 2a.

[0037] Both the above-mentioned movable part 2 and the lens connecting part 1 are rod-shaped structures. The length of the movable part 2 is greater than the length of the lens connecting part 1. The movable part 2 is set as a bent rod that bends inward. A flexible contact part in contact with the skull is attached to the main stress area on the inner side or both the inner and outer sides of the movable part 2. The material of the flexible contact part can be unrestricted and can be set as a TPU / TPE / elastic material soft pad, which has a certain elasticity. During wearing, after the repulsive force between the first magnetic block 3 and the second magnetic block 4 forms a balance with the skull reaction force, a better fixed position within the range of the elastic material soft pad is obtained.

[0038] Moreover, the movable part 2 is detachably connected to the movable fulcrum plate 1a. By replacing the movable part 2, its resilience moment can be adjusted, and the better fixed position in the wearing state can be changed.

[0039] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings.
