Abstract
Description
Technical Field
[0001] This utility model relates to the field of reflector technology, and in particular to a novel ceramic alloy plastic reflector. Background Technology
[0002] In modern optical systems, mirrors are key components, and their performance directly affects the imaging quality and efficiency of the entire system. Traditional mirrors struggle to achieve a perfect balance between optical performance, mechanical performance, and cost. Mirrors made of a single material, such as glass mirrors, while offering excellent optical performance, are fragile, difficult to manufacture, and expensive. Metal mirrors have high reflectivity in certain wavelengths but are prone to oxidation and have poor corrosion resistance. Plastic mirrors, while low-cost and easy to mold, are less effective in terms of optical stability and high-temperature resistance. With the continuous development of optical technology, such as in high-end projectors, lidar, and astronomical observation equipment, higher requirements are placed on the optical performance, thermal stability, mechanical strength, and other aspects of mirrors. Therefore, developing a mirror that can meet the needs of complex optical applications has become an urgent problem to be solved. Utility Model Content
[0003] The purpose of this invention is to provide a novel ceramic alloy plastic reflector that can meet the high-performance requirements of different optical systems for reflectors.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] This utility model proposes a novel ceramic alloy plastic reflector, comprising a ceramic alloy layer and a plastic layer disposed on the ceramic alloy layer. The ceramic alloy layer has a plurality of limiting holes, and the bottom of the plastic layer has a plurality of protrusions that cooperate with the limiting holes. A film layer is disposed on the side of the plastic layer away from the ceramic alloy layer.
[0006] Furthermore, the ceramic alloy layer is provided with functional rotating shafts on both the left and right sides for mounting in HUD bearing slots to achieve the angle adjustment of the reflector.
[0007] Furthermore, the thickness of the ceramic alloy layer is 2–4 mm.
[0008] Furthermore, the thickness of the plastic layer is 1.5 to 2.5 mm.
[0009] Furthermore, the diameter of the limiting hole is 3 to 6 mm.
[0010] The beneficial effects of this invention are as follows: the composite structure of ceramic alloy layer and plastic layer, and the film layer set on plastic layer, allow for precise control of the optical performance of the reflector. The ceramic alloy layer provides the reflector with good mechanical strength and thermal stability, enabling it to work stably in environments with high temperature, high humidity, and mechanical vibration, and preventing deformation and damage, thus improving the service life and reliability of the reflector. The plastic layer reduces the overall manufacturing cost of the reflector, which is conducive to its widespread application in the optical market. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] Please see Figures 1 to 5 This utility model provides an embodiment:
[0019] A novel ceramic alloy-plastic reflector includes a ceramic alloy layer 1 and a plastic layer 2 disposed on the ceramic alloy layer 1. The ceramic alloy layer 1 has several limiting holes 3, and the bottom of the plastic layer 2 has several protrusions 4 that mate with the limiting holes 3. A film layer 5 is disposed on the side of the plastic layer 2 away from the ceramic alloy layer 1. Through the composite structure of the plastic layer 2 and the ceramic alloy layer 1, and the coating on the surface of the plastic layer 2, the optical performance of the reflector can be precisely controlled, meeting the requirements of high-end optical systems for high reflectivity and narrow bandwidth reflection. Simultaneously, the use of the plastic layer 2 reduces the overall manufacturing cost of the reflector and improves production efficiency, which is conducive to the widespread application of this reflector in the optical market.
[0020] In the above embodiments, the ceramic alloy layer 1 is made of titanium carbide and a composite of cobalt or chromium, which has the characteristics of high hardness, high wear resistance, and high temperature resistance. This gives the reflector good mechanical strength and thermal stability, enabling it to work stably in harsh environments such as high temperature, high humidity, and mechanical vibration, and is not prone to deformation and damage, thus improving the service life and reliability of the reflector. The plastic layer 2 is made of PC or COC, which reduces the overall manufacturing cost of the reflector. At the same time, the injection molding process improves production efficiency, which is conducive to the widespread application of the reflector in the optical market. The film layer 5 is made of aluminum film. The reflectivity of aluminum film in the visible light region (wavelength about 400-700nm) can usually reach 80%-90%, and the reflectivity in the infrared band is also relatively high. The specific values vary depending on factors such as the film thickness.
[0021] In the above embodiments, the reflector has a certain curvature to ensure that the image is not distorted and to ensure the consistency of the optical path.
[0022] In the above embodiment, the left and right sides of the ceramic alloy layer 1 are provided with functional rotating shafts 6 for mounting in the HUD bearing slots to achieve the angle adjustment of the reflector.
[0023] In one embodiment of this utility model, the thickness of the ceramic alloy layer 1 is 2-4 mm.
[0024] In one embodiment of this utility model, the thickness of the plastic layer 2 is 1.5 to 2.5 mm, thereby achieving efficient reflection of light of a specific wavelength.
[0025] In one embodiment of this utility model, the diameter of the limiting hole 3 is 3-6 mm.
