Description

[0001] The present invention relates to the technical field of glasses, and in particular to a glasses frame design method for smart glasses, a glasses frame and smart glasses. Background Art

[0002] With the advancement of science and technology, glasses frames have more and more functions. In addition to supporting lenses, many smart glasses frames with Bluetooth, audio, and camera functions have also been derived. Since glasses frames with multiple smart functions are attached with more functional components, the weight of the glasses frames has increased a lot, usually more than twice that of ordinary glasses frames, and most of the above-mentioned functional components are integrated on the temples. Due to the unreasonable structural design of the glasses frames, the force on the bridge of the nose will increase when the user wears smart glasses. Since the pressure on the nose is the most uncomfortable when wearing glasses, the comfort of the user when wearing smart glasses is reduced. In addition, when the user moves, the smart glasses will slide forward with the range of movement, thereby affecting the focal position of the lenses, resulting in a decrease in the user's vision prevention and control effect.

[0045] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0046] See also Figure 1 , Figure 1 : is a flowchart of the steps of the glasses frame design method provided by an embodiment of the present invention. The glasses frame design method for smart glasses of the present invention comprises:

[0047] S1: extracting head curves of multiple users, and performing comparative analysis on the head curves of multiple users to obtain a head wearing curve;

[0048] S2: Design the temple curve according to the head wearing curve, and make the temple curve coincide with the head wearing curve;

[0049] S3: extracting nose curves of multiple users, and performing comparative analysis on the nose curves of multiple users to obtain nose wearing curves;

[0050] S4: Design the nose pad curve according to the nose wearing curve, and make the nose pad curve coincide with the nose wearing curve;

[0051] S5: Design the temples according to the temple curve, and design the nose pads according to the nose pad curve, so that the temples are constrained forward and the nose pads are constrained upward;

[0052] S6: Design the frame according to the position of the nose pads and temples;

[0053] S7: Generate a character model, and use the character model to wear the glasses frame to calculate the first reaction force of the character model on the glasses frame;

[0054] S8: Add functional components to the glasses frame to analyze the second reaction force of the character model on the smart glasses;

[0055] S9: Optimize the eyeglass frame by combining the first reaction force and the second reaction force.

[0056] When designing a glasses frame, a three-dimensional scanner is used to scan the heads of multiple users to obtain head models of the multiple users, and corresponding head curves and nose curves are extracted from the multiple head models, wherein the head curve is the curves on both sides of the head corresponding to when the user wears glasses, and the nose curve is the curve on both sides of the nose bridge. After obtaining the head curves of the multiple users, the average value is calculated from the difference parts of the head curves, and a mean curve is generated, and the overlapping curve is extracted from the overlapping parts of the head curves. Finally, the mean curve and the overlapping curve are connected to form a head wearing curve, and then the temple curve is designed according to the head wearing curve, and the temple curve is made to coincide with the head wearing curve, so that when the user wears the glasses, the temples can fit against both sides of the user's head to convert part of the gravity of the glasses frame on the user's ears into a clamping force on the head, thereby reducing the force on the ears. Similarly, after obtaining the nose curves of multiple users, the average value is calculated from the difference parts of the nose curves, and a mean curve is generated. The overlapping curve is extracted from the overlapping parts of the nose curves. Finally, the mean curve and the overlapping curve are connected to form a nose wearing curve. Subsequently, the nose pad curve is designed according to the nose wearing curve, and the nose pad curve is made to coincide with the nose wearing curve. When the user wears the glasses, the nose pad is constrained both upward and downward, and the temples are constrained forward to avoid the nose pads jumping up and down on the user's nose during exercise, which may cause the glasses frame to move backward under the action of gravity of the temples, affecting the focal length of the lenses and ultimately resulting in a decrease in the glasses' vision protection effect on the user.

[0057] See also Figure 2 , Figure 2 Schematic diagram of wearing the glasses frame provided by the embodiment of the present invention in different states. The human body is usually in a state of standing upright, bending over, exercising, etc. When wearing the glasses frame of the present invention, the gravity G of the glasses frame body is always kept vertically downward, and the glasses support reaction force on the human body in different states is different. Among them, the support reaction force includes the nose support reaction force and the ear support reaction force. When the human body is in an upright state, the directions of the nose support reaction force and the ear support reaction force are both vertically upward ( Figure 1 left position); when the human body is in a 90°bending state, the reaction force on the nose is not affected by the reaction force on the glasses, and the direction of the reaction force on the ear is vertically upward ( Figure 1 In this state, the glasses frame in the prior art will slide down along the direction of gravity due to the lack of temples to hold the user's head; when the human body is in a non-90° bending state, the direction of the nose support force forms an angle with the direction of gravity of the glasses, and the ears are subjected to support forces in two directions at the same time, one of which is vertically upward, and the other is in the opposite direction of the nose support force ( Figure 1In this state, the glasses frame in the prior art will slide off the ears due to the lack of temples to clamp the user's head. At the same time, due to the lack of restraint of the nose pads on the nose, the glasses frame will rotate and slide down along the direction of gravity.

[0058] Taking the right nose pad as an example, the coordinates of the reference center line in contact with the nose are shown in Table 1. When entering the coordinate points in the drawing software, the X, Y, and Z coordinates are positive values, the X axis is the front-to-back direction, the Y axis is the up-down direction, and the Z axis is the left-right direction. The origin of the coordinates is the lower contact point of the stipule. The spline curve is used for the connecting line, and this curve is used as the center structure line of the contact surface. The short axis is 0.4 times the length of this curve, and the height is 0.3 times the length of this curve. The ellipsoid is designed accordingly, and half of the height of the ellipsoid is used as the contact surface to form the contact surface between the nose pad and the nose.

[0059] The left side nose pad is obtained by mirror symmetry;

[0060]

[0061]

[0062] Table 1

[0063] After obtaining the temple curve and the nose pad curve, the temple is designed by thickening and filling the temple curve, and the nose pad is designed by thickening and filling the nose pad curve. Then, the frame is designed according to the position of the temple and the nose pad to form the glasses frame. In order to improve the comfort of the user when wearing the glasses frame, the gravity of the glasses frame also needs to be analyzed.

[0064] When designing the overall eyeglass frame, the position of the center of gravity directly affects the support reaction force of the contact point. When calculating the center of gravity, first take a certain spatial rectangular coordinate system O-xyz in space, and use the segmentation method to divide the eyeglass frame into i particles, each of which corresponds to its own coordinate (x i ,y i ,z i ) and mass m i , the overall weight of the frame is M 总 ;

[0065] Known M 总 =m1+m2+‥+mi, let the center of gravity of the eyeglass frame be G(X, Y, Z), then

[0066] X=(x1m1+x2m2+‥+ximi) / M 总

[0067] Y=(y1m1+y2m2+‥+yimi) / M 总

[0068] Z=(z1m1+z2m2+‥+zimi) / M 总

[0069] Because the overall structure of the glasses frame is axially symmetrical, the center of gravity of the glasses frame is in the plane where the axis of symmetry is located, and its center of gravity is located at a certain point on the axis of symmetry of the glasses frame. Since the direction of gravity of the glasses frame is always vertically downward, the direction of its force arm is always perpendicular to the direction of gravity, the vertical coordinates of the glasses frame can be simplified to the horizontal direction through trigonometric functions, which is convenient for calculation. Finally, the calculated gravity distribution of the glasses frame and the support and reaction forces of the nose bridge and the ears on the glasses frame can be used to calculate the forces on the nose and the ears, so as to judge the user's wearing comfort based on the forces on the ears and the nose.

[0070] In order to more quickly and conveniently analyze the pressure on the ears and nose caused by the glasses frame, the present invention uses RHINO5.0 software to model the glasses frame and analyze the center of gravity position. When performing the center of gravity analysis, the frame model is first generated by the software, and then the overall weight M of the model is calculated by the software. 总 and center of gravity position.

[0071] See also Figure 3 , Figure 3 This is a diagram of the center of gravity position when no functional components are added to the glasses frame design method provided in an embodiment of the present invention. The material of the glasses frame is selected as a polymer material TR90 with a density of 1.1g / cm3. After modeling and calculation by RHINO5.0 software, the overall weight of the glasses frame is 20.02g, the center of gravity position is 43.18mm away from the front edge of the glasses frame, the center of gravity position is 27.85mm away from the center point of contact with the nose pads, and the center of gravity is 78.13mm away from the ear contact point.

[0072] Since the center of gravity of the entire spectacle frame has been calculated, and the spectacle frame is only affected by gravity without bending moment, the spectacle frame can be regarded as a simply supported beam under concentrated load. The nose pad contact point and the ear contact point are the two fulcrums of the simply supported beam. The support reaction force at the fulcrum is the pressure at the point. The support reaction force is equal to the pressure at the point and has the opposite direction. A is the nasal support reaction force, R B is the ear support reaction force, L A is the distance from the center of gravity to the center of the nose pad, L B is the distance from the center of gravity to the ear contact point, M1 is the weight of the frame, and the reaction force formula of the simply supported beam under concentrated load is:

[0073] R A =(L B / (L A +L B ))*M1

[0074] R B =(L A / (LA +L B ))*M1

[0075] After substitution and calculation, we obtain: RA=14.76g, RB=5.26g.

[0076] See also Figure 4 , Figure 4 : is a diagram of the center of gravity position when the functional components are added in the glasses frame design method provided in an embodiment of the present invention. The material of the glasses frame is selected as a polymer material TR90 with a density of 1.1g / cm3. The overall weight of the functional components is 23.4g. After modeling and calculation by RHINO5.0 software, the overall weight of the glasses frame is 20.02g. After adding the functional components, the overall weight is 43.4g. At this time, the center of gravity position of the smart glasses is 97.22mm away from the front edge of the glasses frame, 81.90mm away from the center of gravity of the nose pad contact point, and 24.08mm away from the ear contact point. Substituting the data into the above-mentioned simply supported beam reaction formula, it is obtained: R A =9.86g, R B =33.54g.

[0077]

[0078] Table 2

[0079] By analyzing and comparing the above two sets of data, it is found that the overall weight of smart glasses is 2.17 times that of the glasses frame, and the force on the nose is reduced by 33%. Since the main uncomfortable part when wearing glasses is the nose pad, the decrease in nose pressure significantly improves the comfort. The tolerance of the ears is much greater than that of the nose. After wearing tests, the wearing comfort of smart glasses is significantly improved compared to traditional smart glasses.

[0080] In the above embodiment, when the overall weight of the frame increases, the pressure on the nose is reduced, and the pressure on the ears is increased. However, since the threshold that the ears can withstand is much greater than that of the nose, the increased pressure is not enough to affect the comfort of the ears. The frame design can be optimized according to the calculation method of the center of gravity and the support reaction force to improve the comfort of wearing the frame.

[0081] The glasses frame provided by the present invention can be used to install functional components on the glasses frame. The method provided by the present invention can move the center of gravity of the glasses frame backward, reduce the force on the nose of the user when wearing glasses, and improve the comfort of the user when wearing the glasses frame. Combined with the constraint design of the nose pads and temples in various directions of the present invention, the displacement of the glasses frame is reduced, the wearing is more stable, the stability of the optical path is improved, and the vision prevention and control effect is guaranteed.

[0082] In the above embodiment, the first reaction force includes a first nose reaction force and a first ear reaction force, and the second reaction force includes a second nose reaction force and a second ear reaction force. In order to further improve the wearing comfort of the user, after designing the glasses frame, it is necessary to optimize the glasses frame in combination with the first reaction force and the second reaction force, so that the second nose reaction force is smaller than the first nose reaction force. Since the pressure on the nose is reduced, the comfort of the nose is improved, while the pressure on the ear is increased. However, since the threshold that the ear can withstand is much greater than that of the nose, the increased pressure is not enough to affect the comfort of the ear, and the clamping force between the temples and the user's head relieves part of the pressure to reduce the pressure on the ear, thereby improving the comfort of the ear.

[0083] See also Figure 5 , Figure 5 is a flow chart of step S9 in the spectacle frame design method provided by an embodiment of the present invention, wherein the step of optimizing the spectacle frame further includes:

[0084] S91: Optimize the temple curve and generate a bending curve at the end of the temple curve;

[0085] S92: Adjust the angle of the bending curve so that the angle between the bending curve and the temple curve is 60 degrees;

[0086] S93: Design the bending part according to the bending curve;

[0087] S94: Adjust the position of the nose pad and make the coronal plane of the nose pad fit the nose curve of the character model.

[0088] Since the included angle of the existing frame behind the ear and the horizontal direction is usually 30 to 35 degrees, in the present invention, the included angle of the bending line and the temple is set to 60 degrees.

[0089] like Figure 6-Figure 7 As shown, Figure 6 is a side view of a head when simulating wearing of a spectacle frame in the spectacle frame design method provided by an embodiment of the present invention; Figure 7It is a rear view of the head when simulating the wearing of the glasses frame in the glasses frame design method provided by the embodiment of the present invention. The 60-degree bending curve can make the position of the bending part fit with the hairless area behind the ear to reduce the interference of hair on the stability of the temple. At the same time, the temple and the bending part can be used to increase the components in the functional component, and the center of gravity of the functional component can be moved backward, thereby reducing the pressure of the nose pad on the nose, and enhancing the comfort of the user wearing the glasses. At the same time, the temple can be constrained forward under the action of the bending part to avoid the glasses frame sliding in front of the user's eyes and causing the lens focus to shift, thereby affecting the user's vision prevention and control effect. In addition, the bending part and the temple are fitted together on both sides of the user's head, increasing the contact area between the glasses frame and the user, increasing the clamping force of the temple on the user's head, and reducing the discomfort caused by the temple clamping the user's head. In addition, the clamping of the temple on the user's head can also relieve the pressure on the ears, further reducing the pressure on the ears and improving the comfort of the ears.

[0090] See also Figure 8 , Figure 8 The figure is a diagram of the location of the nose pad coronal plane in the prior art. Most of the nose pad lines in the prior art are straight lines. When standing, the location of the nose pad coronal plane is as follows: Figure 8 As shown, there is no constraint in the upward direction. When bending over or exercising, the nose pads will be displaced due to the lack of upward constraint, which not only causes discomfort, but also changes the distance between the lens and the eye, changes the optical path, and further affects the position of the focal point of the lens optical path, weakening the vision prevention and control effect.

[0091] See also Fig. 9 , Fig. 9 This is a diagram of the landing point of the nose pad coronal surface in the eyeglass frame provided by the embodiment of the present invention. In the embodiment of the present invention, by designing the nose pad as a curve, the contact position and contact curve of the nose pad coronal surface are adjusted, so that when the user wears the eyeglass frame of the present invention, the nose pad coronal surface fits the user's nose curve, so that the nose pad is constrained upward and downward at the same time, avoiding the change of the position of the nose pad causing the change of the position of the eyeglass frame, and preventing the focal position of the lens from moving backward and affecting the user's vision prevention and control effect.

[0092] See also Fig.10 , Fig.10 The figure is a comparison of the nose pad coronal plane landing point position of the present invention and the nose pad coronal plane landing point position in the prior art. Compared with the nose pad landing point position in the prior art, the nose pad landing point contact position in the present invention moves 0.96mm backward and 3.23mm upward. Figure 5 As shown, the contact curve is designed based on the physiological curve of the contact position, and the upward constraint is designed. The constraint reference in each direction Figure 2 .

[0093] See also Figure 11-Figure 12 , Fig.11 It is a schematic diagram of the vertical depression angle of the temple in the prior art; Fig.12 Schematic diagram of the vertical and downward angles of the temples of the present invention. In an embodiment of the present invention, the vertical and downward angles of the temples are 60 degrees ( Fig.12 ), and has a certain physiological curvature, which is different from the 30-35 degree vertical angle requirement of ordinary frames ( Fig.11 ), so that the bending curve can be located in the hairless area behind the ear, and the bending portion is fitted with the hairless area behind the ear to reduce the interference of hair on the stability of the temples. At the same time, the temples and the bending portion can be used to increase the elements in the functional components, and the center of gravity of the functional components can be moved backward, thereby reducing the pressure of the nose pads on the nose and enhancing the comfort of the user wearing the glasses. At the same time, the temples can be constrained forward by the bending portion to avoid the glasses frame sliding in front of the eyes and causing the focus of the lens to shift, thereby affecting the user's vision prevention and control effect.

[0094] In the embodiment of the present invention, since the glasses frame is constrained in four directions, namely, front, back, up and down, the stability of the user when wearing the glasses frame can be improved, and the displacement of the glasses frame on the user's head causing the focus of the lenses to change can be avoided, thereby avoiding a decrease in the user's strength prevention and control effect.

[0095] In order to solve the problems in the prior art, the present invention also provides a glasses frame, which is obtained by adopting the above-mentioned glasses frame design method. The glasses frame includes a frame, temples and nose pads. One end of the temple is rotatably connected to the frame, and the other end is provided with a bending portion. The middle position of the frame is provided with a plug-in groove for the nose pad to be plugged in and connected. The nose pad is arc-shaped and the arc surface of the nose pad fits with the user's Jingming acupoint, the temples fit with both sides of the user's head, and the bending portion fits with both sides of the cranial face behind the user's ears.

[0096] By using the glasses frame provided by the present invention, functional components can be installed on the glasses frame to move the center of gravity of the glasses frame backwards, thereby reducing the force on the user's nose when wearing the glasses, thereby improving the comfort of the user when wearing the glasses frame, and after the user wears the glasses frame, the temples can be fitted with both sides of the user's head to convert part of the gravity of the glasses frame on the user's ears into a clamping force on the head, thereby reducing the force on the ears, and at the same time, the nose pads are constrained upward and downward at the same time to avoid the nose pads jumping up and down on the user's nose during exercise, thereby preventing the glasses frame from moving backwards under the action of the gravity of the temples, affecting the focal length of the lenses, and ultimately resulting in a decrease in the vision protection effect of the glasses on the user.

[0097] By providing a plug-in slot in the middle of the frame for the nose pads to be plugged into the frame, nose pads of different sizes can be replaced according to the nose sizes of different users, so that the nose pads can fit the user's nose more closely, and the glasses frame can be restrained from moving upward and downward by the nose pads, thereby affecting the user's vision prevention and control effect.

[0098] In an embodiment of the present invention, the angle between the bending portion and the temple is 60 degrees, so that the bending curve can be located in the hairless area behind the ear, and the bending portion is located in the hairless area behind the ear to reduce the interference of hair on the stability of the temple. At the same time, the temple and the bending portion can be used to increase the elements in the functional component and move the center of gravity of the functional component backward, thereby reducing the pressure of the nose pad on the nose and enhancing the comfort of the user wearing the glasses. At the same time, the temple can be constrained forward by the bending portion to prevent the glasses frame from sliding in front of the user's eyes and causing the focus of the lens to shift, thereby affecting the user's vision prevention and control effect.

[0099] like Figure 13-Figure 14 As shown, Fig.13 is a schematic diagram of the side structure of the smart glasses provided by an embodiment of the present invention; Fig.14 1 is a schematic diagram of a top view of the smart glasses provided by an embodiment of the present invention. In order to solve the problems in the prior art, the present invention further provides a smart glasses, the smart glasses comprising a functional component and the above-mentioned glasses frame, the functional component comprising a functional part 6, a battery and a connecting seat, the connecting seat is fixed to the temple 1, a component compartment is provided inside the bent portion, the battery is installed in the component compartment and is electrically connected to the connecting seat, and the functional part 6 is detachably connected to the connecting seat.
