First embodiment
The side walls of the reflector 100 require complex features that result in slight shrinkage of the perimeter of the reflective surface. Although these slight shrinkage deformations may not be seen by naked eyes, when the reflective surface of the reflector 100 is subjected to optical coating, the defects are also amplified by the slight shrinkage deformations, so that diffuse reflection or even stray light occurs on the reflective surface of the reflector 100 during reflection, which affects the quality of the reflected image projected by the reflector 100 and finally causes adverse problems such as distortion of the vehicle-mounted HUD imaging projection.
Therefore, referring to fig. 1, the present embodiment provides a reflector 100, which includes a reflector body 10, and a light shielding layer 20 disposed on a periphery of the reflector body 10.
First, since the periphery of the reflector body 10 is slightly deformed due to shrinkage, the light shielding layer 20 is additionally disposed on the periphery of the reflector body 10, that is, the periphery of the reflector body 10, which is slightly deformed due to shrinkage, is covered by the light shielding layer 20, and the light irradiated to the surface of the light shielding layer 20 is absorbed by the light shielding layer 20, so that the periphery of the reflector body 10, which is slightly deformed due to shrinkage, is not reflected, so that the reflector 100 can avoid diffuse reflection and even stray light during reflection, and meanwhile, compared with the prior art in which a light shielding shell is additionally disposed on the reflector 100 of the vehicle-mounted HUD, the reflector 100 can avoid increasing the volume thereof, thereby avoiding increasing the volume of the vehicle-mounted HUD.
Secondly, it should be understood by those skilled in the art that the coverage of the light shielding layer 20 needs to be determined according to the peripheral edge range of the mirror body 10 where slight shrinkage deformation occurs, and therefore, the coverage of the light shielding layer 20 is not particularly limited as long as the light shielding layer 20 can cover the peripheral edge of the mirror body 10 where slight shrinkage deformation occurs and absorb light incident on the surface of the light shielding layer 20.
As described above, the reflector 100 includes the reflector body 10, and the light shielding layer 20 is provided on the periphery of the reflector body 10. Because the periphery of the reflector body 10 can generate slight shrinkage deformation, the light shielding layer 20 is additionally arranged on the periphery of the reflector body 10 which can generate slight shrinkage deformation, namely, the periphery of the reflector body 10 which can generate slight shrinkage deformation is covered by the light shielding layer 20, and the light irradiated to the surface of the light shielding layer 20 is absorbed by the light shielding layer 20, so that the periphery of the reflector body 10 which can generate slight shrinkage deformation can not be reflected, and therefore, the reflector 100 can avoid diffuse reflection and even stray light in the reflection process, and meanwhile, compared with the mode that a light shielding shell is additionally arranged on the reflector 100 of the vehicle-mounted HUD in the prior art, the reflector 100 can also avoid the increase of the volume of the reflector 100, and further avoid the increase of the volume of the vehicle-mounted HUD.
Optionally, the gloss of the light-shielding layer 20 is in a range of 0 to 1.5. Illustratively, the light-shielding layer 20 has a gloss of 0, 0.5, 1, 1.5, or the like.
The gloss is a physical quantity for evaluating the ability of the surface of a material to reflect light under a set of geometrically specified conditions. The gloss degree range of the light-shielding layer 20 is selected to be 0 to 1.5 so as to prevent the surface of the light-shielding layer 20 from reflecting light as much as possible and to absorb light which is irradiated to the surface of the light-shielding layer 20 through the light-shielding layer 20 as much as possible.
In general, the width of the peripheral edge of the mirror 100 where minute shrinkage occurs is in the range of 4mm to 5mm, and the light shielding layer 20 may be selected to have a width in the range of 6mm to 10mm in order to completely cover the peripheral edge of the mirror 100 where minute shrinkage occurs and to prevent the effective area of the reflecting surface of the mirror 100 from being affected as much as possible. Illustratively, the light-shielding layer 20 has a width of 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, or the like.
Although the width of the peripheral edge of the mirror 100 where slight shrinkage occurs does not have a linear correlation with the original area of the reflecting surface of the mirror 100, the width of the light shielding layer 20 may be suitably larger when the original area of the reflecting surface of the mirror 100 is larger, and the width of the light shielding layer 20 should be suitably smaller when the original area of the reflecting surface of the mirror 100 is smaller. Those skilled in the art should be able to select and design properly according to practical situations, and the width of the light shielding layer 20 is not limited specifically, as long as the light shielding layer 20 can completely cover the periphery of the reflector 100 where slight shrinkage deformation occurs and does not affect the effective area of the reflective surface of the reflector 100.
Optionally, the light-shielding layer 20 is formed by a flocking process, a spraying process or a pattern-drying process.
It should be noted that, firstly, the light shielding layer 20 may be adsorbed on the reflection surface by static electricity using light absorbing fluff, or the light shielding layer 20 may be fixed on the reflection surface by a tool (may be adhered by 3M glue) using light absorbing flocking cloth, that is, the light shielding layer 20 may be made by a flocking process, and the manufactured light shielding layer 20 has the advantages of soft hand feeling, no toxicity, no odor, moisture resistance, no delinting, friction resistance, flatness, no gap and the like.
The flocking process is characterized by that it utilizes the physical characteristics of that the like charges repel each other and the opposite charges attract each other to make the pile possess negative charge, and the object to be flocked (i.e. the plant body to be flocked) is placed under the condition of zero potential or grounding condition, and the pile is attracted by plant body by means of different potential, and is vertically accelerated to raise to the surface of the plant body to be flocked, and the surface of the plant body to be flocked is coated with adhesive, so that the pile can be vertically stuck on the plant body to be flocked.
Second, the light shielding layer 20 may be sprayed on the reflective surface by using light absorbing ink, i.e., the light shielding layer 20 may be manufactured by a spraying process. The principle of the spraying process is that compressed air is sprayed out from the center of an air nozzle of a spray gun, a negative pressure area is formed at the front end of an ink nozzle, so that coating in an ink container is sprayed out from an oil nozzle and quickly enters high-speed compressed air flow, liquid-gas phase is rapidly diffused, ink is micronized, the ink flies to the surface of a product in a paint mist shape and is attached to the surface of the product, and the ink mist particles are quickly gathered into a continuous oil film.
Thirdly, the light-shielding layer 20 can also perform light-absorbing pattern-drying treatment on the mold of the reflecting surface to realize light absorption at the periphery of the reflecting surface of the reflector body 10, that is, the light-shielding layer 20 can be manufactured by adopting a pattern-drying process, and the pattern-drying process has the advantages of low cost, rich effect, high speed and the like.
The pattern-sunning process is also called as pattern sunning, pattern biting, pattern etching and pattern etching. The principle of the line-drying process is that chemical liquid medicine (such as sulfuric acid, nitric acid and the like) is adopted to generate chemical reaction with die steel, and the reaction process is controlled to obtain various effects. The process of the line-drying process comprises the following steps: preparation of a mould, film drying, film sticking, exposure, corrosion, cleaning and post-treatment.
Optionally, the mirror body 10 comprises a plane mirror, a spherical mirror or an aspherical mirror. No matter the speculum body 10 is plane reflector, spherical reflector or aspheric surface speculum, all have the lateral wall and need do many complicated structural feature, lead to the periphery can produce slight shrink and deform's problem, consequently, add light shield layer 20 through the periphery at speculum body 10 and can solve above-mentioned problem to avoid speculum 100 to appear diffuse reflection or stray light even in reflection process, simultaneously, can also avoid increasing the volume of speculum 100 and on-vehicle HUD.
In the present embodiment, the projection shape of the mirror body 10 may be a common shape such as a rectangle or a circle. Of course, in other embodiments, the projection shape of the reflector body 10 may also be triangular, trapezoidal, elliptical, and other shapes. It should be noted that no matter what the projection shape of the reflector body 10 is, only the shape of the light shielding layer 20 is changed, and the beneficial effect of adding the light shielding layer 20 at the periphery of the reflector body 10 is not affected.
