A color mixing demonstration device for a twelve-color ring

Abstract

The invention discloses a color mixing demonstration device of a twelve-color ring, which belongs to an optical science education instrument. The color mixing demonstration device of the twelve-color ring comprises a booth, a gear transmission mechanism, a synchronous belt transmission mechanism, a central turntable, a central ball, a left turntable, a right turntable and a motor drive mechanism. The positional relationship between the central turntable and the left turntable and the right turntable is controlled by a motor, so that the color on the central turntable interacts with the color of each area on the left and right turntables. Because the human eye has a visual complementary color function, when two colors are adjacent, when a light stimulation reaction occurs on the retina, an opposing reaction of the adjacent parts will be caused, and the complementary color feeling will be strengthened around the color. Visually, the original color on the central turntable will change. Through the color combination of the invention, all colors and mixing change processes on the standard twelve-color ring can be presented, which plays a good role in principle demonstration and teaching. The device increases interactivity and fun. Through personal interactive experience, the principle of complementary colors and color mixing can be intuitively and vividly understood, making up for the lack of such demonstration devices.

Description

Technical Field

[0001] The present invention relates to the technical field of complementary colors and color mixing applications, and in particular to a color mixing demonstration device of a twelve-color phase ring, which belongs to the category of optical science education instruments. Background Art

[0002] When a part of the retina reacts to light stimulation, it will cause an opposing reaction in the adjacent part. Therefore, the complementary color sensation will be strengthened around the color. In the part where two colors are adjacent, the contrast of complementary colors is most obvious. Human vision always requires a physiological balance for color, that is, when the human eye sees any color, it always requires its relative complementary color. If this complementary color does not appear objectively, the eye will automatically adjust and create this color compensation in vision.

[0003] Color mixing refers to the mixing of two or more colors to produce a new color. When we come into contact with color mixing, we mostly mechanically remember what color the two colors will form by mixing through text or pictures, and we cannot understand it vividly. The present invention uses two complementary colors to produce a strong contrast and visual impact, making a certain color more vivid. Then this color is superimposed on another color. Because of the complementary color effect of human color vision, when two colors are adjacent, when light stimulation occurs on the retina, it will cause an opposing reaction in the adjacent parts, and strengthen the complementary color feeling around the color, so that the color looks different from the original color. The present invention can achieve a visual mixing effect of multiple colors by adding, subtracting or changing the types of original colors, which well solves the current situation of the shortcomings of this type of demonstration device.

[0016] The paddles are provided in a group; the circular coatings at both ends are sprayed green.

[0017] The two groups of blades have circular coatings at both ends sprayed in purple.

[0018] There are three groups of blades; the circular coatings at both ends are sprayed in orange.

[0019] Among them, a bearing rod B, a spherical body, and a synchronous pulley B are arranged in the axial direction of the central ball.

[0020] The spherical body is evenly distributed with three circular coatings along the axis rotation direction, the sizes of which are equal to the central hole, and are respectively arranged as the first spherical surface, the second spherical surface, and the third spherical surface.

[0021] The first spherical surface is spray-painted green as a whole, and its RGB value is the same as the green RGB value of a group of blades.

[0022] The second spherical surface is sprayed in purple as a whole, and the RGB value is the same as the RGB value of the second group of purple blades.

[0023] The third spherical surface is spray-painted in orange as a whole, and its RGB value is the same as the RGB value of the three groups of orange of the blades.

[0024] The synchronous pulleys B are symmetrically arranged at both ends, and the circumferential ratio of the synchronous pulleys B to the synchronous pulley A is 1:2.

[0025] Wherein, the left turntable comprises a left disc, a left bearing rod, and a left synchronous pulley, which rotate around the same axis.

[0027] The surface of the left area is not sprayed.

[0028] The first layer of the second left area is sprayed with purple dots with equal spacing, and the second layer is sprayed entirely with yellow paint.

[0029] The first layer of the left three areas is sprayed with blue dots with equal spacing, and the second layer is sprayed entirely with orange.

[0030] The first layer of the left four areas is sprayed with red dots with equal spacing, and the second layer is sprayed with green dots.

[0031] Wherein, the right turntable includes a right disc, a right bearing rod, and a right synchronous pulley, which rotate around the same axis.

[0032] The right disc is a two-layer structure, the first layer is a transparent hard material, the second layer is a white hard material, there is a certain distance between the two layers, and the two layers are evenly divided into four sector-shaped areas clockwise, namely the first right area, the second right area, the third right area, and the fourth right area.

[0033] The right area has no spray coating on its surface and is mirror-symmetrical to the left area.

[0034] The first layer of the second right area is sprayed with yellow dots with equal spacing, and the second layer is sprayed entirely with purple.

[0037] A keyway hole B is provided at the center of the right synchronous pulley.

[0038] Wherein, the motor drive mechanism is composed of a first button, a second button, a first motor and a second motor, and outputs an electrical signal through a control circuit, so that the first button controls the rotation of the first motor and the second button controls the rotation of the second motor.

[0039] The first button is pressed once to control the first motor to rotate 60° clockwise.

[0041] The first motor is connected to the keyway hole A.

[0042] The second motor is connected to the keyway hole B.

[0043] Beneficial effects of the present invention: Taking the color of the painting of the present invention as an example, the first button is pressed once to control the first motor to rotate 60°, and the center turntable is driven to rotate 60° clockwise through the gear transmission mechanism. Because the circumference ratio of the synchronous pulley B to the synchronous pulley A is 1:2, the center ball rotates 120 degrees upward. Taking the first sphere as an example, when the first sphere is exposed through the center hole, the blade group of the center disk is in a horizontal position. When the first button is pressed again, the center turntable rotates 60° clockwise, the blade group 2 is in a horizontal position, the center ball rotates 120° upward, and the second sphere is exposed through the center hole; and so on, the color of the blade of the center turntable in a horizontal position through the gear transmission mechanism is always the same as the color of the sphere exposed by the center ball.

[0044] Press the second button once to control the second motor to rotate 90° clockwise. Because the right synchronous pulley and the left synchronous pulley are equal in size, the right turntable and the left turntable can rotate synchronously through the synchronous belt transmission mechanism.

[0045] Taking the first sphere and paddle group as an example, when the left area and the right area coincide with the paddle group, because they are transparent and have no coating, both of them are green and unchanged; when the left second area and the right second area coincide with the first paddle, the left second area has the first layer sprayed with purple dots with equal spacing, and the second layer is all sprayed with yellow; the right second area has the first layer sprayed with yellow dots with equal spacing, and the second layer is all sprayed with purple; because yellow and purple are complementary colors, the purple dots in the left second area and the yellow dots in the right second area will be brighter and more vivid, and the first paddle is in the middle of the two, and the green circular pattern coincides with the purple dots and the yellow dots respectively. When the two colors are adjacent, when the light stimulation reaction occurs on the retina, it will cause an opposing reaction in the adjacent part, and strengthen the complementary color feeling around the color. Because the human eye has a visual complementary color function, the original green and purple dots merge into "blue-green", the original green and yellow dots merge into "yellow-green", and the same three green circular patterns become three different "colors", and so on, which can achieve visual changes of multiple colors. Through the color combination of the present invention, all colors and mixed change processes on the standard twelve-color wheel can be presented, which plays a good role in principle demonstration and teaching, and makes up for the shortcomings of such demonstration devices.

[0076] The left turntable 6 comprises a left disc 61, a left bearing rod 62, and a left synchronous pulley 63, which rotate around the same axis.

[0077] The left disc 61 is a two-layer structure, the first layer is a transparent hard material, the second layer is a white hard material, there is a certain distance between the two layers, and the two layers are evenly divided into four sector-shaped areas counterclockwise, namely the first left area 611, the second left area 612, the third left area 613, and the fourth left area 614.

[0078] The surface of the left area 611 is not sprayed.

[0082] The right turntable 7 comprises a right disc 71, a right bearing rod 72, and a right synchronous pulley 73, which rotate around the same axis.

[0083] The right disc 71 is a two-layer structure, the first layer is a transparent hard material, the second layer is a white hard material, there is a certain distance between the two layers, and the two layers are evenly divided into four sector-shaped areas clockwise, namely the first right area 711, the second right area 712, the third right area 713, and the fourth right area 714.

[0084] The right area 711 has no spray coating on its surface and is mirror-symmetrical to the left area.

[0093] The second motor 84 is connected to the keyway hole B 731 .

[0094] Specific implementation case Taking the color selection of the present invention as an example, the first button 81 is pressed to control the first motor 83 to rotate 60° clockwise, the first motor bearing connection key slot hole A253 drives the rear gear 25 to rotate, the rear gear 25 is meshed with the upper gear 24, the upper gear 24 is meshed with the front gear 23, the center turntable 4 and the outer ring 211 of the turntable bearing 21 are fixedly connected with the front gear 23, and the inner ring 212 is fixedly connected with the front end of the bracket 22, so the front gear 23 drives the center turntable 4 and the rear gear 25 to rotate in the same axis in the opposite direction. The inner gear 252 is meshed with the horizontal gear 262, and drives the synchronous pulley A 263 to rotate downward through the bearing rod A 261, and the synchronous pulley A 263 is connected with the synchronous pulley B53. Because the circumference ratio of the synchronous pulley A and the synchronous pulley B is 2:1, the center turntable 4 rotates one circle clockwise, and the center ball 5 rolls up two circles.

[0095] Pressing the second button 82 controls the second motor 84 to rotate 90° clockwise, and the long synchronous belt 32 of the synchronous belt transmission mechanism 3 reversely connects the left synchronous belt pulley 63 and the right synchronous belt pulley 73 through four synchronous belt pulleys C to achieve synchronous reverse rotation.

[0096] Implementation case 1: When the blade group 42 is in a horizontal position, the first sphere 521 is exposed through the center hole 41, and the three colors on the horizontal line are all the same green. When the left area 611 and the right area 711 overlap with the blade group 42, because they are transparent and have no coating, the green color remains unchanged, so in the end the colors of the blade group 42 and the first sphere 521 remain green.

[0097] Implementation Case 2: When the blade group 42 is in a horizontal position, the first sphere 521 is exposed through the center hole 41, and the three colors on the horizontal line are all the same green. When the left second area 612 and the right second area 712 overlap with the blade group 42, the left second area 612 is painted with purple dots at equal intervals on the first layer, and the second layer is all painted with yellow; the right second area 712 is painted with yellow dots at equal intervals on the first layer, and the second layer is all painted with purple; because yellow and purple are complementary colors, the purple dots in the left second area 612 and the yellow dots in the right second area 712 will be brighter and more vivid, and the blade group 42 is in the middle of the two, and the green pattern overlaps with the purple dots and the yellow dots respectively. When the two colors are adjacent, when the light stimulation reaction occurs on the retina, it will cause an opposing reaction in the adjacent part, and strengthen the complementary color feeling around the color. Because the human eye has the function of complementary colors, the original green and purple dots merge into "blue-green", and the original green and yellow dots merge into "yellow-green". The same three green patterns become three different "colors".

[0098] Implementation case three: When the second blade group 43 is in a horizontal position, the second sphere 522 is exposed through the central hole 41, and the three colors on the horizontal line are all the same purple. When the left three areas 613 and the right three areas 713 overlap with the second blade group 43, the first layer of the left three areas 613 is sprayed with blue dots with equal spacing, and the second layer is all sprayed with orange; the first layer of the right three areas 713 is sprayed with orange dots with equal spacing, and the second layer is all sprayed with blue; because blue and orange are complementary colors, the blue dots of the left three areas 613 and the orange dots of the right three areas 713 will be set off brighter and more vivid. The second blade group 43 is in the middle of the two, and the purple pattern overlaps with the blue dots and the orange dots respectively. When the two colors are adjacent, when the light stimulation reaction occurs on the retina, it will cause an opposing reaction in the adjacent part, and strengthen the complementary color feeling around the color. Because the human eye has the visual complementary function, the original purple and blue dots merge into "blue-purple", the original green and yellow dots merge into "red-purple", and the same three purple patterns become three different "colors".

[0099] Implementation Case 4: When the three blade groups 44 are in a horizontal position, the third sphere 523 is exposed through the central hole 41, and the three colors on the horizontal line are all the same orange. When the left four areas 614 and the right three areas 714 overlap with the three blade groups 44, the first layer of the left four areas 614 is sprayed with red dots with equal spacing, and the second layer is all sprayed with green; the first layer of the right four areas 714 is sprayed with green dots with equal spacing, and the second layer is all sprayed with red; because red and green are complementary colors, the red dots of the left four areas 614 and the green dots of the right four areas 714 will be set off brighter and more vivid, and the three blade groups 43 are in the middle of the two. The orange pattern overlaps with the red dots and the green dots respectively. When the two colors are adjacent, when the light stimulation reaction occurs on the retina, it will cause an opposing reaction in the adjacent part, and strengthen the complementary color feeling around the color. Because the human eye has the visual complementary function, the original orange and red dots merge into "red-orange", and the original orange and green dots merge into "yellow-orange", and the same three orange patterns become three different "colors".

[0100] The above are only some combination cases. Through the cooperation of the center turntable, the left turntable and the right turntable, a variety of color visual changes can be achieved. All colors and mixed changes on the standard twelve-color wheel can be presented, which serves a good principle demonstration and teaching purpose. The colors can also be increased to achieve the visual change process of the standard twenty-four-color wheel or more colors.
