Description

Technical Field

[0001] This utility model relates to the field of instrument cover technology, specifically an anti-glare instrument cover with a microprism array. Background Technology

[0002] With continuous economic development and the improvement of people's living standards, daily travel has become increasingly convenient. As a very common means of transportation in daily life, automobiles play a vital role in freight transport and daily travel. Automobiles contain various sophisticated instruments. During the use of these instruments, reflections of external light (such as direct sunlight or ambient light) can cause glare in the instrument display area. To ensure the accuracy and timeliness of data reading for operators, instrument covers are usually installed inside the car.

[0003] Traditional instrument covers are mostly made of ordinary transparent plastic or glass. They only reduce glare by frosting the surface or adding an anti-reflective film, which has limited effect. Moreover, the frosting process reduces the light transmittance to some extent, resulting in insufficient brightness of the instrument display.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an anti-glare instrument cover with a microprism array. Utility Model Content

[0005] The purpose of this invention is to provide an anti-glare instrument cover with a microprism array to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-glare instrument cover with a microprism array, comprising a housing and a positioning component. A groove is formed at the edge of the housing, and a sealing gasket is placed inside the groove. An anti-glare component is provided on the side of the sealing gasket away from the housing. The anti-glare component includes an anti-reflective layer, a base layer, a microprism array layer, and a scratch-resistant layer. A base layer is provided on the outside of the anti-reflective layer, and a microprism array layer is provided on the outside of the base layer. A scratch-resistant layer is provided on the outside of the microprism array layer. A first positioning groove is also formed at the edge of the housing, and second positioning grooves are provided on both sides of the first positioning groove. The positioning component is located at the edge of the anti-glare component near the housing.

[0007] Furthermore, the sealing gasket is disposed between the housing and the anti-reflective layer, and the thickness of the anti-reflective layer is 100-150 nm.

[0008] Furthermore, the thickness of the base layer is 1.5-2 mm, and the thickness of the anti-scratch layer is 5-10 μm.

[0009] Furthermore, the ratio of the number of the first positioning slot to the number of the second positioning slot is 1:2, and the number of the first positioning slot and the number of positioning components are the same.

[0010] Furthermore, the positioning component includes a positioning cylinder, a fixing pin, and an elastic clamping piece, wherein the fixing pin is fixed inside the positioning cylinder, and the elastic clamping piece is provided outside the fixing pin.

[0011] Furthermore, the positioning component also includes sliding pins and sliding grooves, and sliding pins are provided on both sides of the elastic clamping piece, while sliding grooves are provided on both sides of the positioning cylinder.

[0012] Furthermore, the sliding pin extends laterally through the groove, and the diameter of the first positioning groove matches the diameter of the positioning cylinder.

[0013] This utility model provides an anti-glare instrument cover with a microprism array, which has the following beneficial effects:

[0014] 1. In this utility model, the side of the anti-glare component with the positioning component faces the housing, and the positioning cylinder corresponds one-to-one with the first positioning groove. Then, the positioning cylinder is inserted into the first positioning groove. As the sliding pin aligns with the second positioning groove, the sliding pin is embedded in the second positioning groove under the elastic force of the elastic clip. This allows the housing and the anti-glare component to be installed through axial and radial double fixation, effectively preventing loosening.

[0015] 2. The microprism array layer of this utility model is composed of arrayed microprisms. The arrangement direction of the microprism array is parallel to the long side of the instrument display area. Through optical design, the incident strong light is refracted and scattered on the surface of the microprisms, dispersing the originally concentrated reflected light into weak light in multiple directions, thereby avoiding the formation of dazzling glare. This allows operators to clearly read the data without obstruction. Combined with the setting of the base layer and the anti-reflection layer, the overall light transmittance of the instrument cover is greatly improved, effectively solving the problem of dim display caused by traditional frosted treatment.

Detailed Implementation

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figures 1 to 3 As shown, an anti-glare instrument cover with a microprism array includes a housing 1 and a positioning component 7. A first positioning groove 5 is provided at the edge of the housing 1, and a second positioning groove 6 is provided on both sides of the first positioning groove 5. The positioning component 7 is located on the edge of the anti-glare component 4 near the housing 1. The ratio of the number of the first positioning groove 5 and the second positioning groove 6 is 1:2, and the number of the first positioning groove 5 and the positioning component 7 are the same. The positioning component 7 includes a positioning cylinder 701, a fixing pin 702, and an elastic clip 703. The fixing pin 702 is fixed inside the positioning cylinder 701, and the elastic clip 703 is provided outside the fixing pin 702. The positioning component 7 also includes a sliding pin 704 and a sliding groove 705. The sliding pin 704 is provided on both sides of the elastic clip 703, and the sliding groove 705 is provided on both sides of the positioning cylinder 701. The sliding pin 704 passes through the sliding groove 705 laterally. The diameter of the first positioning groove 5 matches the diameter of the positioning cylinder 701.

[0022] The specific operation is as follows: the side of the anti-glare component 4 with the positioning component 7 faces the housing 1, and the positioning cylinder 701 corresponds one-to-one with the first positioning groove 5. Then, the positioning cylinder 701 is inserted into the first positioning groove 5. As the sliding pin 704 aligns with the second positioning groove 6, the sliding pin 704 is embedded in the second positioning groove 6 under the elastic force of the elastic clip 703. This allows the housing 1 and the anti-glare component 4 to be installed through axial and radial double fixation, effectively preventing loosening.

[0023] like Figure 1 and Figure 2As shown, a groove 2 is provided at the edge of the shell 1, and a sealing gasket 3 is placed inside the groove 2. An anti-glare component 4 is provided on the side of the sealing gasket 3 away from the shell 1. The anti-glare component 4 includes an anti-reflection layer 401, a base layer 402, a microprism array layer 403, and an anti-scratch layer 404. The base layer 402 is provided on the outside of the anti-reflection layer 401, and the microprism array layer 403 is provided on the outside of the base layer 402. The anti-scratch layer 404 is provided on the outside of the microprism array layer 403. The sealing gasket 3 is disposed between the shell 1 and the anti-reflection layer 401. The thickness of the anti-reflection layer 401 is 100-150nm, the thickness of the base layer 402 is 1.5-2mm, and the thickness of the anti-scratch layer 404 is 5-10μm.

[0024] The specific operation is as follows: the microprism array layer 403 is composed of microprisms distributed in an array. The arrangement direction of the microprism array is parallel to the long side of the instrument display area. Through optical design, the incident strong light is refracted and scattered on the surface of the microprism, dispersing the originally concentrated reflected light into weak light in multiple directions, thereby avoiding the formation of dazzling glare. This allows operators to clearly read the data without obstruction. Combined with the setting of the base layer 402 and the anti-reflection layer 401, the overall light transmittance of the instrument cover is greatly improved, effectively solving the problem of dim display caused by traditional frosted treatment.

[0025] In summary, when using this anti-glare instrument cover with microprism array, firstly, the sealing gasket 3 is embedded into the groove 2 on the edge of the housing 1. Then, the anti-reflective layer 401 is oriented with one side facing the housing 1, so that the positioning component 7 on the edge corresponds one-to-one with the first positioning groove 5 on the edge of the housing 1. By holding the edge of the anti-glare component 4, the positioning cylinder 701 is inserted into the first positioning groove 5. As the positioning cylinder 701 goes deeper, the elastic clip 703 outside the fixing pin 702 is deformed by pressure. When the positioning cylinder 701 is inserted to the preset depth, the sliding pin 704 is aligned with the second positioning groove 6 on both sides of the first positioning groove 5. At this time, the expansion force of the elastic clip 703 drives the sliding pin 704 to slide outward along the sliding groove 705 on both sides of the positioning cylinder 701 until the sliding pin 704 is embedded in the second positioning groove 6, forming a double fixation of axial positioning of the positioning cylinder 701 and radial locking of the sliding pin 704.

[0026] After positioning, the anti-reflective layer 401 fits tightly against the edge of the groove 2 of the housing 1. The sealing gasket 3 made of nitrile rubber fills all the mating gaps under the pressure of the two, thereby effectively blocking dust and liquid from entering and ensuring that the internal components of the housing 1 are not corroded.

[0027] The base layer 402 is made of polycarbonate (PC), which has good impact resistance and light transmittance. It is integrated with the microprism array layer 403 through injection molding. When external light shines on the anti-glare component 4, the isosceles triangular prisms of the microprism array layer 403 will disperse the strong light with an incident angle of 30°-80° into diffuse reflection light, avoiding the formation of glare. The anti-scratch layer 404 covers the outside of the microprism array layer 403 and adopts a transparent polyurethane coating, which can effectively resist daily wiping and wear. The anti-reflection layer 401 is located on the side of the base layer 402 that contacts the instrument display surface. It adopts a magnesium fluoride (MgF2) film, which can improve the transmittance of the instrument display light and ensure that the display content is clearly visible.

[0028] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
