BRIEF DESCRIPTION OF THE DRAWINGS
[0019] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required for use in the embodiments are briefly introduced below.
[0020] Figure 1The utility model provides a novel thermochromic cover structure.
[0021] Description of the drawings: 10, cover body; 20, first layer of ink; 30, second layer of ink; 40, third layer of ink; 50, character mark area; 60, alignment line; 70, ink groove; 80, fourth layer of ink. DETAILED DESCRIPTION
[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0023] A new type of thermochromic cover structure, referring to Figure 1 , including a cover body 10, the cover body 10 is rectangular, and the four sides of the cover body 10 are arranged with arc corners.
[0024] Reference Figure 1 The first layer of ink 20 is screen-printed on the cover body 10. The first layer of ink 20 is screen-printed on the lower surface of the cover body 10. The first layer of ink 20 is a thermochromic ink. The first layer of ink 20 is a thermochromic ink made of a thermochromic material. The thermochromic ink can change color repeatedly with the rise or fall of temperature. The thermochromic material is composed of microcapsules coated with invisible fuel, color former and temperature control agent. By selecting different temperature control factor materials, colorants that change color in different temperature ranges can be produced.
[0025] Reference Figure 1 In this embodiment, since the first layer of ink 20 uses thermochromic ink, the color change temperature of the first layer of ink 20 is 50 degrees Celsius. When the temperature of the cover body 10 is below 50 degrees Celsius, the cover body 10 appears green, and when the temperature of the cover body 10 is above 50 degrees Celsius, the cover body 10 appears yellow. The thermochromic ink used in the first layer of ink 20 is replaceable, and thermochromic inks of different colors can be replaced according to actual user needs. The thermochromic ink used in the first layer of ink 20 can improve the visual quality of the cover body 10, and at the same time, it is helpful to remind the user that the temperature of the cover body 10 and the display screen on its lower surface is too high, and it is necessary to stop using it or cool down the display screen.
[0026] Further, refer to Figure 1 , the thickness of the first layer of ink 20 is 7 μm.
[0027] Reference Figure 1 The lower surface of the first layer of ink 20 is screen-printed with a second layer of ink 30, and the second layer of ink 30 is screen-printed after the first layer of ink 20 is screen-printed on the cover body 10. The second layer of ink 30 is pure black ink, and the second layer of ink 30 makes the cover body 10 appear black.
[0028] Further, refer to Figure 1 , the thickness of the second ink layer 30 is 4 μm.
[0029] Reference Figure 1 The lower surface of the second ink layer 30 is screen-printed with a third ink layer 40, and the third ink layer 40 is screen-printed after the first ink layer 20 and the second ink layer 30 are screen-printed on the cover body 10. The third ink layer 40 is a matte black ink, and the third ink layer 40 makes the cover body 10 present a matte black effect, and does not reflect strong light under the irradiation of light.
[0030] Further, refer to Figure 1 , the thickness of the third layer of ink 40 is 4 μm.
[0031] Reference Figure 1 The cover body 10 is provided with a character mark area 50 and an alignment line 60, which are located in the same area on the cover body 10. The character mark area 50 displays the production date and model information of the cover body 10. The character mark area 50 and the alignment line 60 are identifiable, and the information on the character mark area 50 needs to be checked on the cover body 10. The character mark area 50 and the alignment line 60 are covered by setting the first layer of ink 20, the second layer of ink 30 and the third layer of ink 40 to improve the aesthetics of the cover body 10.
[0032] Reference Figure 1 The third layer of ink 40 is provided with an ink groove 70 at a position relative to the character mark area 50 and the alignment line 60. The ink groove 70 is arranged in a circle around the cover body 10. The depth of the ink groove 70 is adapted to the thickness of the third layer of ink 40. The third layer of ink 40 is not screen-printed at a position of the cover body 10 relative to the ink groove 70.
[0033] Reference Figure 1 , a fourth layer of ink 80 is screen-printed in the ink groove 70, and the fourth layer of ink 80 is a black high-reflection and high-transparency ink, which makes the position of the character mark area 50 and the alignment line 60 present a black high-reflection and high-transparency setting. When the cover body 10 is exposed to strong light, the position of the character mark area 50 and the alignment line 60 will reflect strong light, thereby forming a sharp contrast with the matte setting of the cover body 10 screen-printed with the third layer of ink 40, so that the information of the character mark area 50 and the alignment line 60 can be read.
[0034] Further, refer to Figure 1 , the thickness of the fourth layer of ink 80 is 4 μm.
[0035] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
