Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, specifically to an easy-to-process and space-saving optical reflection and scattering plastic sheet. Background Technology
[0002] Traditional car taillights are fixed to the vehicle body using hard plastic clips. The structure of hard plastic is complex, and damage is not easily detected. In rainy or snowy weather, water can easily enter and cause short circuits, resulting in failure and posing a safety hazard. In addition, due to manufacturing deviations of parts, taillights may flicker or fail due to poor contact, increasing the risk of collisions. Furthermore, because car taillights are made of hard plastic, their inspection, maintenance, repair, and replacement require a high level of expertise and cannot be replaced by oneself, resulting in high maintenance costs and being time-consuming and labor-intensive. Utility Model Content
[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an easy-to-process and space-saving optical reflection and scattering plastic sheet that can prevent rainwater from entering the car taillights, is easy to process, and allows car owners to check the car taillights themselves.
[0004] To achieve the above objectives, one technical solution adopted by this utility model is: an easy-to-process, space-saving optical reflection and scattering plastic sheet, comprising a lamp layer, an outer scattering plate disposed on the outer surface of the lamp layer, the outer scattering plate comprising an outer plastic sheet and a light scattering coating disposed sequentially from the outside to the inside; an inner reflector disposed on the inner surface of the lamp layer, the inner reflector comprising a reflective coating and an inner plastic sheet disposed sequentially from the outside to the inside; the outer plastic sheet and the inner plastic sheet are made of PC, PP, PVC or PET material; a sealant for sealing the lamp layer is disposed between the outer scattering plate and the inner reflector.
[0005] Preferably, the size of the lamp layer is smaller than the size of the outer diffuser plate and the inner reflector plate, the lamp layer is disposed in the middle between the outer diffuser plate and the inner reflector plate, and the sealant is disposed around the lamp layer.
[0006] Preferably, an external heat insulation layer is provided between the outer diffuser plate and the outer surface of the lamp layer to prevent the outer diffuser plate and the lamp bead layer of the lamp layer from directly contacting each other.
[0007] Preferably, an inner heat-insulating layer is provided between the inner reflector and the inner surface of the lamp layer to prevent direct contact between the inner reflector and the lamp bead layer of the lamp layer.
[0008] Preferably, a white oil layer is provided between the reflective coating and the inner plastic sheet. The white color increases the brightness and reflects the light that passes through the reflective coating back.
[0009] Preferably, the inner plastic sheet is black, which is also to prevent light leakage and provide a light-blocking effect.
[0010] Preferably, an ultraviolet isolation layer is provided between the outer plastic sheet and the light scattering coating.
[0011] The advantages of this easy-to-process, space-saving optical reflection and scattering plastic sheet are as follows: The outer and inner plastic sheets of this application are made of PC, PP, PVC, or PET materials, which have a certain degree of flexibility. Compared with hard plastics, it eliminates the high-temperature injection molding process, greatly reducing energy consumption; the processing requirements are low, no custom molds are needed, and only the cutting parameters need to be adjusted to adapt to the needs of different vehicle models; the assembly difficulty is low, with a user-friendly design, only requiring simple bonding of the outer scattering plate and the inner reflector, without the need for snap-fitting, facilitating quick on-site replacement or DIY installation; it has a wide range of applications, with excellent optical performance and durability, suitable for diverse applications such as automotive interior and exterior trim, advertising signs, and traffic facilities; the sealant further optimizes the sealing of the lamp layer, preventing external water from entering the lamp layer; the optical reflection and scattering plastic sheet uses a composite layer instead of hard plastic and LEDs, reducing the thickness of the taillight and saving space.

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0019] Example 1
[0020] See Figure 1As shown, this embodiment discloses an easy-to-process, space-saving optical reflection and scattering plastic sheet, including a lamp layer 1. Generally, the lamp layer 1 includes a PCB board 1a and LED beads 1b. The LED beads are soldered onto the PCB board and then encapsulated by a package 1c to form the lamp layer 1. An outer scattering plate 2 is provided on the outer surface of the lamp layer 1. The outer scattering plate 2 includes an outer plastic sheet 2a and a light scattering coating 2b arranged sequentially from the outside to the inside. An inner reflector 3 is provided on the inner surface of the lamp layer 1. The inner reflector 3 includes a reflective coating 3a and an inner plastic sheet 3b arranged sequentially from the outside to the inside. The outer plastic sheet 2a and the inner plastic sheet 3b are made of materials including but not limited to PC, PP, PVC, or PET. Compared with hard plastics, this material has a certain degree of flexibility. A sealant 4 is provided between the outer scattering plate 2 and the inner reflector 3 to seal the lamp layer 1 and prevent rainwater from entering the lamp layer 1.
[0021] like Figure 1 As shown, the size of the lamp layer 1 is smaller than that of the outer diffuser plate 2 and the inner reflector plate 3. The lamp layer 1 is located in the middle between the outer diffuser plate 2 and the inner reflector plate 3, and the sealant 4 is located around the lamp layer 1.
[0022] Example 2
[0023] See Figure 2 As shown, this embodiment discloses an easy-to-process and space-saving optical reflection and scattering plastic sheet. Unlike the first embodiment, an outer heat insulation layer 5 is provided between the outer scattering plate 2 and the outer surface of the lamp layer 1, which can prevent the outer scattering plate 2 and the lamp bead layer of the lamp layer 1 from directly contacting each other.
[0024] In addition, an inner heat insulation layer 6 can be provided between the inner reflector 3 and the inner surface of the lamp layer 1. Similarly, direct contact between the inner reflector 3 and the lamp bead layer of the lamp layer 1 can be avoided.
[0025] Example 3
[0026] See Figure 3 As shown, this embodiment discloses an easy-to-process and space-saving optical reflection and scattering plastic sheet. Unlike embodiment two, the inner reflector 3 includes a reflective coating 3a, an inner plastic sheet 3b, and a white oil layer 3c. The white oil layer 3c is disposed between the reflective coating 3a and the inner plastic sheet 3b, which can increase the brightness of the inner plastic sheet 3b and reflect the light that passes through the reflective coating 3a back.
[0027] Correspondingly, the inner plastic sheet 3b is black, which prevents light from leaking out and serves as a light-blocking function.
[0028] Example 4
[0029] See Figure 4As shown, this embodiment discloses an easy-to-process and space-saving optical reflection and scattering plastic sheet. Unlike embodiment three, in this embodiment, the outer scattering plate 2 includes an outer plastic sheet 2a, a light scattering coating 2b, and an ultraviolet isolation layer 2c (i.e., UV layer). The ultraviolet isolation layer 2c is disposed between the outer plastic sheet 2a and the light scattering coating 2b.
[0030] Since the outer plastic sheet 2a and inner plastic sheet 3b of Examples 1 to 4 are made of PC, PP, PVC or PET materials, they have a certain degree of flexibility. Compared with hard plastics, they eliminate the high-temperature injection molding process, greatly reducing energy consumption. The processing requirements are low, no custom molds are required, and only the cutting parameters need to be adjusted to adapt to the needs of different vehicle models. The assembly difficulty is low, and the user-friendly design only requires simple bonding of the outer diffuser plate 2 and the inner reflector plate 3. No snap-fit is required, which is convenient for quick on-site replacement or DIY installation.
[0031] The easy-to-process, space-saving optical reflection and scattering plastic sheets described in Examples 1 to 4 can be applied not only to automotive parts (such as automotive taillights), but also to a variety of other applications such as automotive interior and exterior trim, advertising signs, and traffic facilities.
[0032] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
