[0029] Example 1

[0030] The embodiment provides a glasses frame with impact resistance function, including mirror frame 1 and the mirror leg 2 of hinged in mirror frame 1 both sides, still including:

[0031] Front flexible impact resistance layer 3 is located in the side of mirror frame 1 and face contact, front flexible impact resistance layer 3 is equipped with the front hole structure 4 for reducing glasses frame front impact, and the front hole structure 4 is along longitudinal and evenly arranged along the length direction of mirror frame 1.

[0033] Front flexible impact resistance layer 3 is located in the side of mirror frame 1 and face contact, for buffering frontal impact, reduces the oppression of mirror frame 1 to nasal arch and zygomatic bone etc. parts, improves the safety and comfort of wearing. Front flexible impact resistance layer 3 is usually a flexible structure layer, and can be made of thermoplastic rubber and other rubber materials, which has good elasticity and buffering performance. The shape of front flexible impact resistance layer 3 matches the side of mirror frame 1 and face contact. Front flexible impact resistance layer 3 can be fixedly connected with mirror frame 1 by pasting, injection molding and other ways.

[0034] The front hole structure 4 further enhances the ability of the front flexible impact-resistant layer 3 to reduce the impact on the front of the glasses frame, while also reducing weight, increasing air permeability, etc. The front hole structure 4 is composed of multiple holes arranged uniformly along the length of the frame 1 and longitudinally. The front hole structure 4 is an integral structure with the front flexible impact-resistant layer 3.

[0037] Embodiment 2:

[0038] The embodiment provides a glasses frame with impact resistance, which has the following technical features in addition to the technical solutions of the above embodiments.

[0039] The front hole structure 4 includes:

[0040] The inner side hole 40 is near the middle of the frame 1, and the inner side hole 40 penetrates in the up-down direction.

[0041] The outer side hole 41 is near the hinge of the frame 1 and the temple 2, and the outer side hole 41 is opened from top to bottom with a bottom hole.

[0042] The inner side hole 40 is used to allow air to circulate in the front-back direction when the glasses are subjected to a frontal impact, avoiding discomfort due to excessive local pressure, while also dispersing the impact force to a wider area, reducing the concentrated pressure on the nasal bridge. The inner side hole 40 is a hole that penetrates the front flexible impact-resistant layer 3 in the up-down direction, which allows air to circulate freely and forms a permeable structure in mechanics, which helps to disperse stress. The inner side hole 40 is near the middle of the frame 1. This position corresponds to the area above the nasal bridge, which is a key part when the glasses are subjected to frontal impact, and the inner side hole 40 can be specifically buffered and ventilated in this area.

[0043] The outer side hole 41 is used to absorb part of the impact force when the glasses are subjected to a frontal impact, especially the torsional and tensile forces that may occur near the hinge of the temple 2. The outer side hole 41 can play a certain buffering role to prevent the hinge part from being deformed due to excessive force, thereby ensuring the overall structural stability of the glasses frame. The outer side hole 41 is provided from top to bottom with a bottom hole and is a non-through hole. This structure design absorbs impact force by deforming the internal space of the hole under the premise of ensuring structural strength. The existence of the bottom hole avoids the weakening of the structural strength that may be caused by the through hole, and at the same time, the space of the hole can be used for buffering. The outer side hole 41 is integrally formed with the front flexible impact layer 3.

[0044] Embodiment 3:

[0045] The embodiment provides a glasses frame with an impact resistance function. In addition to the technical solutions of the above embodiments, the glasses frame has the following technical features.

[0046] The inner side hole 40 and the outer side hole 41 are in gradient density distribution, and the distribution density of the inner side hole 40 is higher than that of the outer side hole 41.

[0047] In terms of mechanical distribution, the middle part of the frame 1 is a part that is subjected to a larger force when subjected to a frontal impact, and the concentrated inner side hole 40 can more effectively disperse the impact force to protect the nose bridge and the malar bone and other parts. The hinge part of the frame 1 and the temple 2 needs to maintain a certain structural strength to resist hinge deformation, and the lower density of the outer side hole 41 can better retain the structural strength of this part while reducing the weight, so that the overall mechanical properties of the glasses frame are optimized, and different degrees of buffering and support are achieved in different parts.

[0048] In terms of buffering effect, the inner side hole 40 has a high distribution density, which means that there are more holes in the middle part of the frame 1 to absorb and disperse the frontal impact force. When the glasses are subjected to a frontal impact, these dense holes can convert the impact force into other forms of energy through deformation of the hole wall, compression of air, etc., thereby better buffering the impact and reducing the damage to the face.

[0049] In terms of overall stability, the gradient density distribution design takes into account the high requirements of the middle part of the frame 1 for buffering impact, and also considers the structural stability of the outer side of the frame 1. By reasonably adjusting the density of the inner side hole 40 and the outer side hole 41, the glasses frame can effectively buffer the impact force when subjected to impact, and can maintain the overall shape and structural stability, avoid deformation or damage of the glasses frame due to the local structure being too weak, and prolong the service life of the glasses frame.

[0050] Embodiment 4:

[0051] The embodiment provides a spectacle frame with an anti-impact function.

[0052] The inner hole 40 and the outer hole 41 are both pentagonal in shape.

[0053] In terms of stress dispersion, the edge corners of the pentagonal shape can effectively disperse stress. When the spectacle frame is impacted by external force, the impact force is conducted and dispersed along the edges and corners of the pentagonal shape, avoiding stress concentration in a certain point or place, thereby reducing the possibility of rupture or damage of the spectacle frame due to excessive local stress.

[0054] In terms of tear resistance, compared with a circular hole, the tear resistance of the pentagonal hole is significantly improved. This is because the corners of the pentagonal shape increase the connection points and support structures of the material, so that the materials around the hole can better support and restrain each other when subjected to stretching or tearing force, and are not easy to be torn. In actual use, the spectacle frame may be subjected to forces in various directions, and the high tear resistance of the pentagonal hole can ensure that the structure of the spectacle frame remains intact even if subjected to a certain degree of external pulling force during long-term use, thereby prolonging the service life.

[0055] Embodiment 5:

[0056] The embodiment provides a spectacle frame with an anti-impact function, which comprises the technical solutions of the above-mentioned embodiments and the following technical features.

[0057] The side hole structure 6 is a side through hole 60 penetrating the side flexible anti-impact layer 5 in the up-down direction.

[0058] The side through hole 60 absorbs energy by deformation when subjected to lateral impact; reduces the weight of the temple 2, improves the wearing comfort; the through design enables water flow or air to pass through smoothly during cleaning, carrying away dirt. The side through hole 60 is a hole structure completely penetrating the side flexible anti-impact layer 5, which is integrally formed with the side flexible anti-impact layer 5.

[0059] Embodiment 6:

[0060] The embodiment provides a spectacle frame with an anti-impact function, which comprises the technical solutions of the above-mentioned embodiments and the following technical features.

[0061] The side through hole 60 is uniformly arranged in the position close to the temple and the skin behind the ear along the length direction of the temple 2.

[0062] In terms of pressure distribution and comfort, the uniform arrangement of the holes along the length of the temple 2 makes the pressure distribution on the temple 2 to the temple and the skin behind the ear more uniform. Compared with the temple 2 without these holes or with unevenly distributed holes, it can reduce the local excessive pressure, thereby reducing the compression of these parts caused by long-term wearing of glasses, making the wearer feel more comfortable.

[0063] In terms of ventilation and heat dissipation, since the side through holes 60 are close to the temple and the skin behind the ear, which are areas prone to sweating, the uniform arrangement of the through holes can better circulate air to the parts of the temple 2 in contact with the skin, accelerate heat dissipation, reduce the stuffy feeling and sweating caused by long-term wearing of glasses, and improve the comfort of wearing.

[0064] Embodiment 7:

[0065] The embodiment provides an eyeglass frame with impact resistance, which comprises the technical solutions of the above-mentioned embodiments and has the following technical features.

[0066] The hole shape of the side through hole 60 is X-shaped.

[0067] When the glasses are subjected to a lateral impact, the unique geometry of the X-shaped structure can effectively absorb and disperse the impact force. The intersection and four edges of the X-shaped structure will elastically deform when subjected to force, and the impact force will be converted into elastic potential energy of the structure through this deformation, thereby consuming a large amount of impact energy. Compared with simple shapes such as circular or square holes, the X-shaped structure can disperse the impact force in more directions, avoiding the concentration of impact force in a certain place, which can cause damage to the temple 2 or cause injury to the side of the wearer's head. For example, when accidentally hit from the side during exercise, the X-shaped side through hole 60 can significantly reduce the impact force transmitted to the temple and the back of the ear by the temple 2, protecting the wearer from injury while maintaining the structural integrity of the eyeglass frame and reducing the risk of damage to the glasses.

[0068] At the same time, the X-shaped structure forms a reinforcing rib effect inside the temple 2. This reinforcing rib structure greatly improves the bending strength of the temple 2, making it better able to maintain its shape when subjected to lateral forces and not easily bend or break. Studies have shown that compared with the temple 2 without special shaped holes or with other simple shaped holes, the temple 2 designed with X-shaped side through holes 60 can improve the bending strength. This means that when subjected to a larger impact, the X-shaped design can provide stronger structural support to the eyeglass frame, effectively resist the impact, and ensure the safety of the wearer.

[0069] Embodiment 8:

[0070] The embodiment provides an eyeglass frame with impact resistance, which comprises the technical solutions of the above-mentioned embodiments and has the following technical features.

[0071] The end of the temple 2 is provided with a flexible anti-off sleeve 7, which comprises:

[0072] A sleeve body 70 is sleeved at the end of the two temples 2 respectively;

[0073] An anti-off arm 71 is connected to the top of the sleeve body 70 at one end and extends to the bottom of the side through hole 60 at the other end, which is matched with the shape of the side through hole 60.

[0074] The flexible anti-off sleeve 7 is used to prevent the temple 2 from sliding off the head during wearing, enhance the stability of wearing glasses, and improve the comfort of wearing.

[0075] The sleeve body 70 closely fits the end of the temple 2, increases the friction between the temple 2 and the side of the head, and makes the glasses more stable during wearing. Meanwhile, the soft material can buffer the pressure of the temple 2 on the ear and reduce the discomfort during wearing. The sleeve body 70 is usually a sleeve structure with an internal space matched with the end of the temple 2, which can be tightly sleeved on the end of the temple 2 by its elasticity without additional connecting parts, and is kept in place on the temple 2 by the friction and elasticity of the material.

[0076] The anti-off arm 71 is used to cooperate with the side through hole 60 to form a mechanical anchor, further enhance the ability of the flexible anti-off sleeve 7 to prevent the temple 2 from sliding off, and ensure the stability of the glasses during wearing. The end connected to the sleeve body 70 of the anti-off arm 71 is usually an elongated strip structure, and the end inserted into the bottom of the side through hole 60 is a columnar structure matched with the shape of the side through hole 60, so as to be smoothly inserted and reach the bottom of the hole. The anti-off arm 71 can be made of materials such as silica gel with certain flexibility and strength, which can ensure that it will not be easily broken during insertion and use, and can work with the sleeve body 70 to provide stable anti-off function. The anti-off arm 71 and the sleeve body 70 can be integrally connected; and the side through hole 60 is connected by insertion and cooperation, which forms a stable mechanical connection by the cooperation of the shape and the side through hole 60.
