Description

Technical Field

[0001] The invention belongs to the field of mobile phone blue light protection, and in particular relates to a mobile phone blue light protection device with adjustable angle. Background Art

[0002] In recent years, with the rapid development of the electronics industry, mobile phones have far surpassed their original communication functions in today's high-speed technological development. Mobile phones have gradually acquired the functions of computers, MP3s, navigation systems, game consoles, and cameras. Mobile phones have become an indispensable communication and entertainment tool in people's lives, and have had a profound impact on people's daily cultural life.

[0003] The visible light emitted by existing mobile phone displays contains a large amount of irregular short-wave blue light, which is very harmful to human eyes. Therefore, people generally feel eye fatigue after watching the display for a long time, especially those who have night vision habits. As mobile phones have more and more functions and are used more and more frequently, the issue of eye health has attracted great attention.

[0004] The existing solution is to stick a layer of anti-blue light mobile phone film on the mobile phone screen. When using a mobile phone with a mobile phone film, watching the screen for a long time will not only easily cause problems such as dry eyes, blurred vision, etc., but the mobile phone film is easy to reflect light, which will also affect the light transmittance and feel of the mobile phone screen. It is also easy to cause peeling, warping, poor fit with the mobile phone screen, etc., which makes most people who have high requirements for mobile phone use unwilling to stick an anti-blue light mobile phone film. Therefore, the present invention proposes an angle-adjustable mobile phone anti-blue light device, which can prevent the blue light from the screen from damaging the eyes without sticking a mobile phone film.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. In the present invention, light is generated by LED lamps and passes through the light curtain window to form a light curtain above the mobile phone screen. When the light emitted by the mobile phone screen passes through the light curtain, the light curtain will block and reflect the blue light in the mobile phone screen light, thereby protecting the user's eyes. There is no need to post a blue light protection mobile phone film, which is more convenient to use;

[0028] 2. In the present invention, a transparent cylinder with a plurality of transparent films of different colors is sleeved on the outside of the LED tube, so that after the light generated by the LED tube passes through the transparent film, the transparent film only allows light of the same color to pass through, thereby changing the color of the emitted light. Due to the different absorption, blocking or reflectivity of blue light by different colors, the light intensity of the mobile phone screen light passing through the light curtain is also different, resulting in changes in the brightness of the light, so that users can adjust according to different usage environments;

[0029] 3. In the present invention, by setting a light curtain adjustment mechanism, the height, angle and thickness of the light curtain can be adjusted through different adjustment wheels, so that users can customize the light curtain according to their own usage habits, thereby improving the user's usage experience;

[0030] 4. In the present invention, by connecting an elastic dark film between the top of the lifting light blocking block and the top of the shell, the light emitted by the LED lamp can be prevented from bypassing the lifting light blocking block and directly emitting from the light curtain window, thereby improving the stability of the light of the light curtain;

[0031] 5. In the present invention, an anti-diffusion plate is arranged on the side of one end of the two light-blocking plates. When the gap between the light-blocking plates is changed, the gap between the two anti-diffusion plates will also change. The edge of the anti-diffusion plate will block some light with a large incident angle from entering the gap between the two anti-diffusion plates. When the light propagates between the two anti-diffusion plates, the light will experience multiple reflections, and the propagation path of the light will be extended. As the light propagates, the intensity of the light will be further reduced, which will cause the light to be darker after being emitted from the light-blocking plates, so that the thickness of the light curtain appears to be more uniform, and the light curtain is more stable, thereby avoiding affecting the user's perception;

[0032] 6. In the present invention, when adjusting the angle of the light curtain, first press the limit block, and the limit block drives the limit inner gear ring to move through the second rotating cylinder, and the limit inner gear ring disengages from the engagement with the limit gear, so that the rotating shaft and the adjusting bevel gear can rotate freely, avoiding affecting the swing of the driven bevel gear, and avoiding the lifting and lowering light blocking block driving the first rotating cylinder and the driven bevel gear to rotate around the adjusting bevel gear through the double-headed screw, thereby changing the gap between the two light blocking plates, so that multiple adjustment mechanisms can be adjusted relatively independently, which is more convenient to use.

[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0047] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0048] like Figure 1-Figure 5As shown, an angle-adjustable mobile phone anti-blue light device provided by the present invention comprises a housing 1, a circuit board 10 is arranged inside the housing 1, a battery 11 is also installed inside the housing 1, the battery 11 is electrically connected to the circuit board 10, a charging socket 9 is electrically connected to the circuit board 10, one end of the charging socket 9 extends out of the housing 1, the charging socket 9 is used to charge the battery 11, a mobile phone interface 3 is electrically connected to the circuit board 10, one end of the mobile phone interface 3 extends out of the housing 1, the mobile phone interface 3 is used to connect to the mobile phone charging port, and the mobile phone interface 3 can be used to charge the mobile phone. The housing 1 is provided with a power switch 5, which is electrically connected to the circuit board 10. A dark tube 12 is fixedly installed inside the housing 1, and an LED tube 18 is installed inside the dark tube 12, which is electrically connected to the circuit board 10. A light-transmitting port 19 for light emission is provided on the side of the dark tube 12 close to the mobile phone interface 3. A light curtain window 2 is provided on the side of the housing 1 close to the mobile phone interface 3. Light passing through the light curtain window 2 can form a light curtain above the mobile phone, which can block part of the blue light emitted by the mobile phone to protect people's eyesight. The housing 1 also includes:

[0049] A brightness adjustment mechanism 8 is rotatably mounted on the housing 1 , and an output end of the brightness adjustment mechanism 8 is sleeved on a dark tube 12 . The brightness adjustment mechanism 8 is used to change the color of the light curtain emitted from the light curtain window 2 .

[0050] like Figure 2-Figure 5 As shown, an angle-adjustable mobile phone anti-blue light device is provided by the present invention. In this embodiment, the brightness adjustment mechanism 8 includes a transparent cylinder 81 rotatably mounted on the shell 1, and the transparent cylinder 81 is sleeved on the concealed tube 12. The outer surface of the transparent cylinder 81 is provided with a plurality of transparent films 82, and the plurality of transparent films 82 form a complete cylinder on the transparent cylinder 81. Each of the transparent films 82 has a different color, and one end of the transparent cylinder 81 extending out of the shell 1 is fixedly connected to a brightness adjustment wheel 83.

[0051] The present invention provides an angle-adjustable blue light protection device for a mobile phone. In this embodiment, there are five transparent films 82 , and the colors of the five transparent films 82 are yellow, green, red, blue and transparent, respectively.

[0052] When the light emitted by the LED lamp tube 18 penetrates the blue transparent film 82, it will form a blue light curtain. When the blue light shines on the blue light curtain, due to the similar colors, the light curtain may reflect part of the blue light, making the light curtain look brighter. At the same time, the blue light curtain will also absorb part of the blue light, but compared with light curtains of other colors, its absorption degree may be lower, which is suitable for environments with higher light intensity, such as daytime under the sun.

[0053] The blue transparent film 82 is provided because: although blue light may cause damage to the eyes, a moderate amount of blue light is beneficial to the human body, and short-term use will not cause damage to the eyes, and it can be used in special environments.

[0054] When the light emitted by the LED lamp tube 18 penetrates the yellow or green transparent film 82, it will form a yellow or green light curtain. When blue light shines on the yellow or green light curtain, due to the complementary relationship of colors, the light curtain may absorb more blue light. At the same time, the light curtain may reflect less blue light, causing the light curtain to look darker, which is suitable for environments with lower light intensity, such as cloudy days, evenings, etc.

[0055] When the light emitted by the LED lamp tube 18 penetrates the red transparent film 82, it will form a red light curtain. When blue light shines on the red light curtain, the light curtain will absorb most of the blue light due to the large color difference. At the same time, the light curtain reflects very little blue light, and the light curtain will look very dark, which is suitable for environments without external lights, such as at night.

[0056] When the light emitted by the LED lamp tube 18 penetrates the transparent color-transmitting film 82, it will not change the color of the light, and thus a white light curtain will be formed. When blue light is irradiated onto the white light curtain, since white is a mixture of all colors, the light curtain will reflect part of the blue light. At the same time, the white light curtain will also absorb part of the blue light, but compared with light curtains of other colors, the amount of blue light reflected and absorbed may be more balanced, which is suitable for using mobile phones in normal environments, such as inside a house during the day.

[0057] like Figure 4-Figure 5 As shown, an angle-adjustable mobile phone anti-blue light device is provided by the present invention. After adjusting the brightness of the light curtain, in order to prevent the brightness adjustment wheel 83 from rotating at will, in this embodiment, the brightness adjustment mechanism 8 also includes a positioning component, and the positioning component includes a mounting groove opened on the side of the shell 1 near the brightness adjustment wheel 83, and a positioning column 86 is slidably connected inside the mounting groove. A second compression spring 85 is connected between the positioning column 86 and the mounting groove, and a plurality of positioning grooves 84 are opened on the side of the brightness adjustment wheel 83 near the positioning column 86. The number and position of the positioning grooves 84 are compatible with a plurality of transparent films 82, and one end of the positioning column 86 can be plugged into the positioning groove 84.

[0058] When adjusting the brightness of the light curtain, it is only necessary to rotate the brightness adjustment wheel 83, the positioning groove 84 will squeeze the positioning column 86, and squeeze the positioning column 86 out of the positioning groove 84. After the transparent film 82 is adjusted into place, under the action of the second compression spring 85, the positioning column 86 is inserted into the positioning groove 84 again, thereby fixing the brightness adjustment wheel 83 to prevent the brightness adjustment wheel 83 from rotating at will.

[0059] like Figure 1-Figure 3 and Figure 6-Figure 12 As shown, an angle-adjustable mobile phone anti-blue light device is provided by the present invention. In this embodiment, a light curtain adjustment mechanism is also installed inside the shell 1, and the output end of the light curtain adjustment mechanism is located between the light-transmitting port 19 and the light curtain window 2. The light emitted by the LED lamp tube 18 passes through the output end of the light curtain adjustment mechanism and is emitted from the light curtain window 2. The light curtain adjustment mechanism is used to control the height, angle and thickness of the light curtain emitted from the light curtain window 2, so that the user can adjust it according to his own usage habits.

[0060] like Figure 1-Figure 3 and Figure 6-Figure 12 As shown, an angle-adjustable mobile phone blue light protection device provided by the present invention, in this embodiment, the light curtain adjustment mechanism includes a mounting plate 17 fixedly mounted in the housing 1, a rotating seat 16 is rotatably connected to the mounting plate 17, one end of the rotating seat 16 is slidably connected to a lifting light blocking block 14, and a light-transmitting hole 15 for light to pass through is opened on the lifting light blocking block 14;

[0061] In order to prevent the light emitted by the LED lamp tube 18 from bypassing the lifting light blocking block 14 and emitting from the light curtain window 2, an elastic dark film 13 is connected between the top of the lifting light blocking block 14 and the top of the housing 1, and the elastic dark film 13 can block the propagation of light;

[0062] The light curtain adjustment mechanism also includes a height adjustment mechanism 6, which is mounted on a rotating seat 16. The output end of the height adjustment mechanism 6 is connected to the lifting light blocking block 14. The height adjustment mechanism 6 is used to drive the lifting light blocking block 14 to move up and down, thereby adjusting the height of the light transmission hole 15, and further adjusting the height of the light curtain formed by the light transmission hole 15.

[0063] The light curtain adjustment mechanism further includes an angle adjustment mechanism 4, which is mounted on a mounting plate 17, and an output end of the angle adjustment mechanism 4 is connected to a rotating seat 16, and the angle adjustment mechanism 4 is used to drive the rotating seat 16 to rotate, and the rotating seat 16 drives the light-transmitting hole 15 to rotate, so that the angle between the light-transmitting hole 15 and the horizontal plane can be adjusted, and then the angle of the light curtain formed by the light-transmitting hole 15 can be adjusted;

[0064] In order to allow the light curtain to be emitted from the light curtain window 2, the width of the light curtain window 2 is made greater than twice the width of the light transmission hole 15, thereby increasing the angle range of the light curtain;

[0065] The light curtain adjustment mechanism also includes a thickness adjustment mechanism 7, which is installed on a rotating seat 16, one end of the thickness adjustment mechanism 7 extends out of the shell 1, the other end of the thickness adjustment mechanism 7 is installed on the lifting light blocking block 14, and the output end of the thickness adjustment mechanism 7 extends to the inside of the light-transmitting hole 15. The thickness adjustment mechanism 7 is used to adjust the thickness of the light curtain formed by light passing through the light-transmitting hole 15.

[0066] like Figure 10-12 As shown, an angle-adjustable mobile phone anti-blue light device is provided by the present invention. In this embodiment, the height adjustment mechanism 6 includes a first screw 63 rotatably connected to the inside of the rotating seat 16, one end of the first screw 63 is threadedly connected to the lifting light blocking block 14, and a height adjustment rod 61 is rotatably connected to the rotating seat 16, a second transmission pair 62 is connected between one end of the height adjustment rod 61 and the first screw 63, and one end of the height adjustment rod 61 extending out of the shell 1 is fixedly connected to a height adjustment wheel 64.

[0067] In this embodiment, the second transmission pair 62 is a bevel gear pair.

[0068] like Fig.10 and Fig.12 As shown, an angle-adjustable mobile phone anti-blue light device is provided by the present invention. In this embodiment, the angle adjustment mechanism 4 includes an angle adjustment rod 42 rotatably connected to the mounting plate 17, and a first transmission pair 43 is connected between one end of the angle adjustment rod 42 and one end of the rotating seat 16, and one end of the angle adjustment rod 42 extending out of the shell 1 is fixedly connected to an angle adjustment wheel 41.

[0069] In this embodiment, the first transmission pair 43 is a sprocket pair.

[0070] like Figure 6-Figure 9 As shown, an angle-adjustable mobile phone blue light protection device provided by the present invention is provided. In this embodiment, the thickness adjustment mechanism 7 includes two light baffles 72, and the two light baffles 72 are slidably connected to the inside of the lifting light baffle block 14, and the two light baffles 72 are symmetrically distributed about the center line of the light transmission hole 15, and one end of the two light baffles 72 extends to the inside of the light transmission hole 15. The lifting light baffle block 14 is also rotatably connected to two double-headed screws 73, and one end of the two light baffles 72 on the same side is respectively threadedly connected to the two ends of the double-headed screw 73, and a third transmission pair 71 is connected between the two double-headed screws 73;

[0071] When the thickness of the light blocking plate 72 is small, the light entering the light transmission hole 15 will be reflected from the edge of the light blocking plate 72, which will cause the light of the light curtain to look very messy, affecting the user's perception. Therefore, in the present embodiment, the two light blocking plates 72 are fixedly connected to the side surfaces of one end of the light blocking plates 72 located inside the light transmission hole 15 with an anti-diffusion plate 716. When the gap between the light blocking plates 72 is changed, the gap between the two anti-diffusion plates 716 will also change. The edge of the anti-diffusion plate 716 will block some light with a larger incident angle from entering the gap between the two anti-diffusion plates 716. When the light propagates between the two anti-diffusion plates 716, the light will experience multiple reflections, and the propagation path of the light will be extended. As the light propagates, the intensity of the light will be further reduced, which will cause the light to be darker after being emitted from the light blocking plate 72, making the light curtain look more uniform in thickness and more stable, thereby avoiding affecting the user's perception.

[0072] The thickness adjustment mechanism 7 also includes an adjustment component, which is installed on the rotating seat 16. One end of the adjustment component is connected to a double-headed screw 73, and the other end of the adjustment component is installed on the shell 1. The adjustment component is used to drive the double-headed screw 73 to rotate, and the double-headed screw 73 drives the two light baffles 72 to move toward or away from each other, so that the size of the gap between the two light baffles 72 can be adjusted, and then the thickness of the light passing through the gap between the two light baffles 72 can be adjusted.

[0073] like Figure 6-Figure 9 As shown, an angle-adjustable mobile phone anti-blue light device is provided by the present invention. In this embodiment, the adjustment component includes a first rotating cylinder 76 rotatably mounted on the rotating seat 16 and a third rotating cylinder 715 rotatably mounted on the shell 1. One end of the first rotating cylinder 76 is slidably connected to one end of a double-headed screw 73 to avoid affecting the lifting and lowering of the lifting and lowering light blocking block 14. The other end of the first rotating cylinder 76 is fixedly connected to a driven bevel gear 77. A rotating shaft 75 is installed at one end of the third rotating cylinder 715 extending into the interior of the shell 1. One end of the rotating shaft 75 is fixedly connected to an adjusting bevel gear 74. The rotating shaft 75 and the adjusting bevel gear 74 are meshingly connected. The end of the third rotating cylinder 715 extending out of the shell 1 is fixedly connected to a thickness adjusting wheel 78.

[0074] like Figure 6-Figure 9As shown, an angle-adjustable mobile phone anti-blue light device provided by the present invention is provided. When adjusting the angle of the light curtain, in order to prevent the lifting light blocking block 14 from driving the first rotating cylinder 76 and the driven bevel gear 77 to rotate around the adjusting bevel gear 74 through the double-headed screw 73, thereby causing the gap between the two light blocking plates 72 to be changed, in this embodiment, the rotating shaft 75 is rotatably mounted on one end of the third rotating cylinder 715. When the lifting light blocking block 14 drives the first rotating cylinder 76 and the driven bevel gear 77 to swing, the driven bevel gear 77 will drive the adjusting bevel gear 74 to rotate around the third rotating cylinder 715, thereby preventing the driven bevel gear 77 from driving the first rotating cylinder 76 and the double-headed screw 73 to rotate;

[0075] In order to drive the adjustment bevel gear 74 to rotate, a second rotating cylinder 712 is slidably installed inside the third rotating cylinder 715, and one end of the second rotating cylinder 712 close to the rotating shaft 75 is fixedly connected to a limiting internal gear ring 714, and one end of the rotating shaft 75 is fixedly connected to a limiting gear 713, and the limiting gear 713 can mesh with the limiting internal gear ring 714, and the side surface of one end of the second rotating cylinder 712 extending out of the thickness adjustment wheel 78 is fixedly connected to a limiting block 711, and a limiting groove 710 adapted to the limiting block 711 is opened on the side of the thickness adjustment wheel 78, and the limiting block 711 is slidably connected to the inside of the limiting groove 710, and a first compression spring 79 is connected between the limiting block 711 and the thickness adjustment wheel 78. Initially, the limiting gear 713 is meshed with the limiting internal gear ring 714, and the thickness of the limiting internal gear ring 714 is less than the distance between the left side of the limiting block 711 and the side wall of the limiting groove 710.

[0076] When adjusting the angle of the light curtain, first press the limit block 711, and the limit block 711 drives the limit inner gear ring 714 to move through the second rotating cylinder 712, and the limit inner gear ring 714 is disengaged from the limit gear 713, so that the rotating shaft 75 and the adjusting bevel gear 74 can rotate freely to avoid affecting the swing of the driven bevel gear 77; after the angle adjustment is completed, release the limit block 711, and under the action of the first compression spring 79, the limit block 711 drives the limit inner gear ring 714 The limit gear 713 is meshed with the limit inner gear ring 714 again, and when the teeth of the limit inner gear ring 714 are blocked by the teeth of the limit gear 713, the thickness adjustment wheel 78 can be slowly turned, and the thickness adjustment wheel 78 drives the limit inner gear ring 714 to rotate through the limit block 711. When the teeth of the limit inner gear ring 714 and the teeth of the limit gear 713 are misaligned, the first compression spring 79 will push the limit block 711 to move, and the limit block 711 drives the limit inner gear ring 714 to mesh with the limit gear 713 again.

[0077] Working principle:

[0078] Insert the mobile phone interface 3 into the charging port of the mobile phone, and the mobile phone can be charged through the battery 11. Press the power switch 5 to turn on the power of the LED lamp tube 18. The LED lamp tube 18 generates light, and the light is irradiated onto the transparent cylinder 81 from the light-transmitting port 19, and penetrates the transparent cylinder 81 and the transparent film 82 in turn. The light penetrating the transparent film 82 passes through the gap between the two anti-diffusion plates 716 and is emitted from the light curtain window 2 to form a light curtain. When the light from the mobile phone passes through the light curtain, the light curtain will block and reflect it, filter out part of the blue light, and prevent the blue light from causing damage to the user's eyes.

[0079] The color of the light curtain can also be adjusted according to different usage environments. When adjusting, the brightness adjustment wheel 83 is rotated, and the brightness adjustment wheel 83 drives the transparent cylinder 81 and the color-transmitting film 82 to rotate, so that the different color-transmitting films 82 are rotated to one side of the light-transmitting port 19. When the light generated by the LED lamp tube 18 passes through the color-transmitting film 82, the light will only leave the color corresponding to the color-transmitting film 82, so that the color of the different light curtains can be adjusted. When the light from the mobile phone penetrates the light curtains of different colors, the light from the mobile phone blocked or reflected by the light curtain is different according to the different colors of the light curtain, so that different brightness can be formed for use in different external environments;

[0080] The height, angle and thickness of the light curtain can also be adjusted according to personal habits;

[0081] When adjusting the height of the light curtain, the height adjustment wheel 64 is rotated, and the height adjustment wheel 64 drives the height adjustment rod 61 to rotate, and the height adjustment rod 61 drives the first screw 63 to rotate through the second transmission pair 62, and the first screw 63 drives the lifting light blocking block 14 to rise and fall in the rotating seat 16, thereby adjusting the height of the light transmission hole 15 on the lifting light blocking block 14, so that light passes through the light transmission holes 15 at different heights, and the height of the light curtain from the mobile phone screen can be adjusted;

[0082] When adjusting the angle of the light curtain, the limit block 711 is pressed, and then the angle adjustment wheel 41 is rotated, the angle adjustment wheel 41 drives the angle adjustment rod 42 to rotate, the angle adjustment rod 42 drives the rotating seat 16 to rotate through the first transmission pair 43, and the rotating seat 16 drives the lifting light blocking block 14 to rotate, so that the angle between the light transmission hole 15 on the lifting light blocking block 14 and the horizontal plane can be adjusted, so that the light passes through the light transmission hole 15 at different emission angles, so that the angle between the light curtain and the mobile phone screen can be adjusted;

[0083] When adjusting the thickness of the light curtain, rotate the thickness adjusting wheel 78, and the thickness adjusting wheel 78 drives the second rotating cylinder 712 and the limiting inner gear ring 714 to rotate through the limit block 711, and the limiting inner gear ring 714 drives the limiting gear 713 and the rotating shaft 75 to rotate, and the rotating shaft 75 drives the driven bevel gear 77 to rotate through the adjusting bevel gear 74, and the driven bevel gear 77 drives the double-headed screw 73 to rotate through the first rotating cylinder 76, and the double-headed screw 73 drives the two light blocking plates 72 to move closer to or away from each other, so that the size of the gap between the two light blocking plates 72 can be adjusted, thereby affecting the thickness of the light curtain passing through the light-transmitting hole 15.
