Description

Technical Field

[0001] The present invention relates to the technical field of glasses, and in particular to a glasses leg and a preparation method thereof, a glasses frame and glasses. Background Art

[0002] Since the 21st century, with the rise of electronic products and the influence of various factors, the myopia rate in my country has shown a clear upward trend. Myopia has become the primary problem of eye health for Chinese people, especially young people. At present, myopia surgery still has certain disadvantages, and most people with myopia still choose to wear glasses. Due to the long-term wearing of glasses, the comfort and durability of the glasses legs are particularly important.

[0003] The materials of glasses legs mainly include metal, plate, ordinary plastic, composite, wood, TR90, carbon fiber, etc. Metal glasses legs are impact-resistant, wear-resistant, tough, low in friction coefficient, easy to replace, but easy to cause skin allergies. Plate is a new type of plastic. Plate glasses legs are strong, firm, of good quality, and durable, but the surface is easily corroded by sweat, and the plate will age and turn white. Ordinary plastic glasses legs are cheap, fast in production, and have a variety of styles and colors, but the structure is poor in resistance, and they are prone to aging and breaking over time. Composite glasses legs are stable and reliable, but they are complex to make, difficult to process, and costly. Wooden glasses legs are light in weight and have beautiful patterns, but they are not comfortable to wear. The wood has poor flexibility and is prone to wear, corrosion, and breaking. TR90 glasses legs have the characteristics of light weight, super toughness, impact-resistant, wear-resistant, bright colors, and low friction coefficient. They can effectively prevent the glasses legs from breaking, but the surface is spray-painted, which is not environmentally friendly, the paint layer is not durable and easy to peel off, and the glasses legs cannot be adjusted. Carbon fiber glasses legs have more advantages than glasses legs made of other materials. They are light, corrosion-resistant, and not easy to deform. They have the two major characteristics of carbon fiber's strong tensile strength and fiber softness and processability. They are sturdy, durable, and have a strong color. However, one disadvantage of carbon fiber material is that it is relatively brittle, so carbon fiber glasses legs will break after being bent to a certain degree. They are not as tough as metal glasses legs. Carbon fiber materials are expensive and the processing procedures are relatively complicated. Once carbon fiber glasses legs are damaged, they are difficult to repair. Summary of the invention

[0049] Carbon fiber glasses legs have more advantages than glasses legs made of other materials. They are light, corrosion-resistant, and not easy to deform. They have the two major characteristics of carbon fiber's strong tensile strength and fiber softness and processability. They are sturdy, durable, and have a strong color. However, one disadvantage of carbon fiber material is that it is relatively brittle, so carbon fiber glasses legs will break after being bent to a certain degree. They are not as tough as metal glasses legs. Carbon fiber materials are expensive and the processing procedures are relatively complicated. Once carbon fiber glasses legs are damaged, they are difficult to repair.

[0050] In view of this, in order to improve the toughness of carbon fiber glasses legs, the present invention proposes a thermosetting resin hybrid fiber composite glasses leg, which is optimized and innovated on the basis of ordinary composite materials glasses legs and carbon fiber glasses legs, and effectively improves the rigidity, toughness, friction resistance and corrosion resistance of the glasses legs through a multi-layer structure design combination. Figures 1 to 4 FIG. 1 is an embodiment of the eyeglass leg provided by the present invention. Figure 1 and Figure 3 As shown, in this embodiment, the temple includes a skeleton layer 1, a support layer 2 and a strength layer 3 which are arranged in sequence from the inside to the outside (the "from the inside to the outside" refers to the direction from the inner center of the temple to the outer surface). The material of the skeleton layer 1 includes high-toughness organic fiber, the material of the support layer 2 includes high-modulus carbon fiber and a first thermosetting resin, and the material of the strength layer 3 includes high-strength carbon fiber and a second thermosetting resin.

[0051] In the technical solution provided by the present invention, through the three-layer structural design combination of the skeleton layer 1, the support layer 2 and the strength layer 3, and the coordination of the high-strength carbon fiber and the high-modulus carbon fiber, the rigidity, toughness, friction resistance and corrosion resistance of the temples are effectively improved, thereby effectively improving the use stability and service life of the temples.

[0052] In some embodiments of the present invention, the high-tenacity organic fiber includes but is not limited to any one of nylon fiber, aramid fiber, and ultra-high molecular weight polyethylene fiber. The material has good tenacity, a wide range of sources, and relatively low cost.

[0053] In some embodiments of the present invention, the skeleton layer 1 is composed of a mesh structure woven from the high-toughness organic fibers. The strength and toughness of the skeleton layer 1 can be improved by setting the mesh structure, thereby further improving the strength and toughness of the temples.

[0054] Furthermore, in some embodiments of the present invention, the mesh diameter of the mesh structure is 0.5-2 mm. In this way, the strength and toughness of the skeleton layer 1 are optimized.

[0055] In some embodiments of the present invention, the high modulus carbon fiber includes any one of carbon fibers of models M40, M55, and M60, and the strength of the carbon fiber is relatively high.

[0056] In some embodiments of the present invention, the first thermosetting resin includes but is not limited to any one of epoxy resin, phenolic resin, unsaturated polyester resin, and urea-formaldehyde resin. The resin has good compatibility with the high modulus carbon fiber, good mechanical properties, wide sources, and relatively low cost.

[0057] Furthermore, in some embodiments of the present invention, the content of the resin in the support layer 2 is 40-60%, that is, the first thermosetting resin accounts for 40-60% of the total mass of the high modulus carbon fiber and the first thermosetting resin. By controlling the content of the resin in the support layer 2, the strength and toughness of the support layer 2 can be effectively ensured to be good.

[0058] Preferably, in some embodiments of the present invention, the support layer 2 is composed of the high modulus carbon fiber in the form of a two-dimensional planar woven structure and the first thermosetting resin. In this way, by arranging the high modulus carbon fiber to be composited with the first thermosetting resin in a two-dimensional planar woven structure, the toughness of the support layer 2 can be further improved.

[0059] Furthermore, in the support layer 2, the two-dimensional planar woven structure includes any one of a plain woven structure, a twill woven structure, and a satin woven structure. That is, the high modulus carbon fiber raw material can directly select carbon fiber having the above two-dimensional planar woven structure, so that the source of the high modulus carbon fiber is wide and the cost is relatively low.

[0060] In some embodiments of the present invention, the high-strength carbon fiber includes any one of carbon fiber models T300, T700, T800, and T1000, and the strength of the carbon fiber is relatively high. Further, the specification of the high-strength carbon fiber includes any one of 3K, 6K, 12K, 24K, and 36K.

[0061] In some embodiments of the present invention, the second thermosetting resin includes but is not limited to any one of epoxy resin, phenolic resin, unsaturated polyester resin and urea-formaldehyde resin, and has good compatibility with the high-strength carbon fiber, good mechanical properties, wide sources and relatively low cost. It should be noted that in the present invention, the specific materials of the first thermosetting resin and the second thermosetting resin can be the same or different, as long as both are selected within the material selection range provided above, and both belong to the protection scope of the present invention.

[0062] Furthermore, in some embodiments of the present invention, the content of the resin in the strength layer 3 is 40-60%, that is, the second thermosetting resin accounts for 40-60% of the total mass of the high modulus carbon fiber and the second thermosetting resin. By controlling the content of the resin in the strength layer 3, the strength and toughness of the strength layer 3 can be effectively ensured to be good.

[0063] Preferably, in some embodiments of the present invention, the strength layer 3 is composed of the high-strength carbon fiber in the form of a two-dimensional planar woven structure and the second thermosetting resin. In this way, by arranging the high-strength carbon fiber to be composited with the second thermosetting resin in a two-dimensional planar woven structure, the strength and toughness of the strength layer 3 can be further improved.

[0064] Furthermore, in the strength layer 3, the two-dimensional plane woven structure includes any one of a plain woven structure, a twill woven structure, and a satin woven structure. That is, the high-strength carbon fiber raw material can directly select carbon fiber with the above-mentioned two-dimensional plane woven structure, so that the source of the high-strength carbon fiber is wide and the cost is relatively low. It should be noted that the two-dimensional plane woven structure of the carbon fiber in the support layer 2 and the strength layer 3 can be the same or different, as long as both are selected within the woven structure provided above, they all belong to the protection scope of the present invention.

[0065] Furthermore, in some embodiments of the present invention, the total content of the resin in the temple is preferably 40-60%, that is, the total mass fraction of the resin in the material constituting the temple is controlled to be 40-60%. In this way, the strength and toughness of the temple can be well balanced, and the weight of the temple can be reduced as much as possible to achieve lightweight.

[0066] In some embodiments of the present invention, the thickness of the skeleton layer 1 is 0.5-1 mm. In addition, the thickness of the support layer 2 is 0.2-0.6 mm. In addition, the thickness of the strength layer 3 is 0.2-0.5 mm. In this way, the strength, toughness and appearance of the temples can be taken into consideration.

[0067] Preferably, in some embodiments of the present invention, refer to Figure 2 As shown, the temple has a first side facing the human face and a second side opposite to the first side, and the second side is provided with a groove extending along the length direction of the temple. By providing a groove on the second side of the temple, it is possible to reduce the material usage of the temple, reduce the weight of the temple, and achieve lightweighting of the temple while ensuring the performance of the temple. Specifically, in the present invention, the extension length of the groove can be equal to or less than the length of the temple, or multiple grooves can be provided along the length direction of the temple, and weight reduction can be achieved. The best weight reduction effect can be achieved when the extension length of the groove is equal to the length of the temple. However, in actual applications, it may be necessary to consider the performance requirements such as the overall strength and structural stability of the temple, and reasonably arrange the specific position and related dimensions of the groove. In addition, when the extension length of the groove is smaller than the length of the temple, or when a plurality of the grooves are provided along the length direction of the temple, it is preferred that the grooves are distributed at one end of the temple for connecting to the frame, which is more conducive to ensuring the wearing comfort of the end of the temple for contacting the human body (ear).

[0068] In some embodiments of the present invention, a plurality of grooves are provided at intervals along the length direction of the glasses leg, so as to ensure the strength and other properties of the glasses leg while minimizing the weight. The side view of the glasses leg provided with the grooves is as follows: Figure 2 As shown. Further, in the present invention, it is preferably set that the overall thickness of the temple is 0.5-2 mm. The minimum thickness within this range refers to the thickness of the temple where the groove is opened. Here, part of the composite layer in the temple is removed and hollowed out, but it is necessary to ensure that the removed thickness is not less than the thickness of the skeleton layer 1, so that at least the skeleton layer 1 is retained to ensure the structural strength of the temple; and the maximum value within this range refers to the maximum thickness at the position where the groove is not opened and the skeleton layer 1, the support layer 2 and the strength layer 3 are retained. Within the above thickness range, the weight reduction effect of the temple is better, and the overall strength and structural stability can also be guaranteed.

[0069] In some embodiments of the present invention, a support structure may be provided between the bottom wall and the side wall of the groove to further improve the structural stability and strength of the temple and make it more beautiful. The support structure may be integrally formed with the temple, for example, when the temple is injection molded, the bottom wall and the side wall of the groove are directly injection molded to form an arc transition, or the support structure may be provided separately on the basis of the temple structure. Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the support structure is arranged in such a manner that two support bars 4 are provided on two opposite inner sides of the groove, each of the support bars 4 is connected to the inner side wall and the bottom wall of the groove, and the support bar 4 extends along the length direction of the groove (that is, extends along the length direction of the temple). In this way, the support bar 4 can play a role similar to that of a reinforcing rib, thereby improving the structural stability and strength of the temple. The extension length of the support bar 4 can be the same as the length of the groove, or it can be less than the length of the groove. In the embodiment of the present invention, it is preferably the same as the length of the groove, and the supporting effect is better.

[0070] In some embodiments of the present invention, the material of the support strip 4 includes a thermoplastic resin and high-strength short-connected carbon fibers, which are combined by hot pressing, and the hot pressing temperature can be flexibly adjusted, and the thermoplastic resin accounts for 20-40% of the total mass of the thermoplastic resin and the high-strength short-connected carbon fibers. In this way, the mixing dispersion of the thermoplastic resin and the high-strength short-connected carbon fibers is good, and the mechanical properties of the support strip 4 are better, which can better play a supporting role.

[0071] Furthermore, the thickness of the support strip 4 is 0.5-1 mm. Preferably, in some embodiments of the present invention, the support strip 4 is as follows: Figure 4 The crescent-shaped arrangement shown in FIG. 1 is used. In this case, the thickness of the support bar 4 refers to the maximum thickness of the support bar 4 (i.e. Figure 4 In this way, by arranging the support bar 4 in a crescent shape, the support bar 4 is better fitted with the groove, which is conducive to strengthening the temple of the glasses.

[0072] In some embodiments of the present invention, the high-strength short-circuited carbon fiber includes any one of carbon fibers of model T300, T700, T800, and T1000. Furthermore, the specifications of the high-strength carbon fiber include any one of 3K, 6K, 12K, 24K, and 36K. In this way, the strength of the carbon fiber is relatively high. It should be noted that in the present invention, the specific materials of the high-strength carbon fiber and the high-strength short-circuited carbon fiber can be the same or different, as long as both are selected within the material selection range provided above, and both belong to the protection scope of the present invention.

[0073] In some embodiments of the present invention, the thermoplastic resin includes but is not limited to any one of polyethylene, polypropylene, polyvinyl chloride, and polystyrene. In this way, the thermoplastic resin has good compatibility with the high-strength short-link carbon fiber, and the resin has a wide source, relatively low cost, and high mechanical strength.

[0074] In some embodiments of the present invention, the leg length of the glasses leg (the "leg length" refers to the projection length of the glasses leg in the vertical direction, which can be specifically referred to in Figure 1 The length A shown in the figure is 135 to 145 mm. In addition, the front end of the eyeglass leg (the "front end" refers to the end of the eyeglass leg connected to the frame) and the width (the "width" refers to the size of the eyeglass leg in the horizontal direction, which can be specifically referred to in Figure 2 The dimension B shown in FIG. 1 is 0.5 to 1.5 cm. In addition, the height of the temple (the “height” refers to the dimension of the temple in the vertical direction, which can be specifically referred to in FIG. Figure 3 The size C) is 0.2-0.6 cm. In this way, the overall structure of the glasses leg is more suitable for human body wearing. In addition, the overall configuration of the glasses leg adopts a streamlined design, conforms to the ergonomic design, is smooth and close to the ear, and helps to relieve ear pressure.

[0075] Based on the above-mentioned glasses leg provided by the present invention, the present invention also provides a method for preparing the glasses leg, which is prepared by compression molding, and specifically comprises the following steps:

[0076] The various layers of structures used to form the temples of the glasses are stacked and laid, and then placed in a molding machine for hot pressing and curing to obtain the temples of the glasses.

[0077] In the preparation method of the present invention, for the structural layer made of a mixture of carbon fiber and resin, a prepreg in which the carbon fiber and resin are premixed in proportion can be directly selected and injected into a specific metal mold, and then processed by heating and heat curing molding. Specifically, the fiber raw material or prepreg used to prepare the structure of each layer of the glasses leg is cut according to the product size to obtain a molding material; the mold is cleaned and coated with a release agent, and then the molding material is placed in the mold in the order of the skeleton layer 1, the support layer 2, and the strength layer 3, and the mold is closed. When screwing, lubricating oil can be applied to the screws to ensure smooth subsequent mold opening. Next, the mold with the molding material placed inside is placed on a preheated molding machine, and 3 to 4 depressings are performed with an interval of 10 to 20 seconds, and then hot pressing curing molding is performed. After curing, the molding material is cooled and demolded to obtain the glasses leg.

[0078] The glasses legs prepared by the specific metal pair molding usually include two pairs of glasses legs, one for the left glasses leg and the other for the right glasses leg. In addition, for the embodiment in which the glasses legs also include a support bar 4, after the molded material is placed into the mold in the order of the skeleton layer 1, the support layer 2, and the strength layer 3, the step of placing two support bars 4 at the connection between the bottom wall and the side wall of the groove is also included, and then the mold closing process is performed.

[0079] In some embodiments of the present invention, the parameters of the hot pressing curing molding are set as follows: hot pressing temperature is 130-180°C, pressure is 0.5-2MPa, pressing time is 20-60min, and pressing is maintained for 40-60min after stopping heating.

[0080] Furthermore, the present invention also provides a glasses frame, the glasses frame comprising two glasses legs and a frame, the two glasses legs are respectively a left glasses leg and a right glasses leg, and can be formed by a specific metal mold, and the structure and constituent materials of the glasses legs or their preparation process refer to the above embodiments. It can be understood that, since the glasses frame provided by the present invention adopts all the technical solutions of the above-mentioned glasses legs and the preparation method of the present invention, it at least has all the beneficial effects brought by the above embodiments, which will not be repeated here one by one.

[0081] Furthermore, the present invention also provides a pair of glasses, the glasses comprising a glasses frame and glasses lenses installed in the glasses frame, the glasses frame comprising two glasses legs and a glasses frame, the two glasses legs being a left glasses leg and a right glasses leg respectively, which can be formed by a specific metal mold, and the structure and constituent materials of the glasses legs or the preparation method thereof refer to the above embodiments. It can be understood that, since the glasses frame provided by the present invention adopts all the technical solutions of the above glasses legs and the preparation method thereof of the present invention, it at least has all the beneficial effects brought by the above embodiments, which will not be described one by one here.
