技术领域 technical field
本实用新型涉及一种后视镜,特别是涉及一种具有显示单元的后视镜。The utility model relates to a rearview mirror, in particular to a rearview mirror with a display unit.
背景技术 Background technique
中国TW公告编号第484532号案「电子式后视镜结构改良」,揭示了将后视镜原有反射后方影像的机能,再搭配一个倒车影像摄影显示的机能于后视镜上,借此让后方显示上更无死角,以提升驾驶上的安全性。China TW Bulletin No. 484532 Case "Structure Improvement of Electronic Rearview Mirror" reveals that the rearview mirror's original function of reflecting rear images is combined with a reversing image photography display function on the rearview mirror, thereby allowing There are no dead spots on the rear display to improve driving safety.
然而,因为倒车影像用的显示器安装在后视镜的镜片组后方,就需要考量穿透与反射上的需求,且又需要考量整体镜片组反射后方影像的原始目的是否会被影响,所以最终于镜片组上往往会有二个不同穿透与反射率的第一区间及第二区间,第一区间为了符合显示器显影所特别制作,而第二区间则为了一般反射后方影像所制作。However, because the display for the reversing image is installed behind the lens group of the rearview mirror, it is necessary to consider the requirements for penetration and reflection, and it is also necessary to consider whether the original purpose of the overall lens group to reflect the rear image will be affected, so in the end. There are usually two first and second zones with different transmittance and reflectivity on the lens group. The first zone is specially made to meet the display development, while the second zone is made for the general reflection of the rear image.
参阅图1,中国TW发明专利第I270483号案,后视镜的玻璃镜片,还进一步的揭露镜片镀膜及穿透、反射率的应用,主要结构组成在于,于后视镜装设一个显示器(图未示),该后视镜上的镜片11就相对该显示器设计成型为穿透率较佳的窗框12,而其它未对应显示器的镜面部位13则镀膜时取得较佳的反射率,相对就会有较低的穿透率,就此可以使显示器得到较佳的效果,而达到辅助显示的功效。Referring to Fig. 1, China TW Invention Patent No. I270483, the glass lens of the rearview mirror further discloses the application of lens coating, penetration and reflectivity. The main structural composition is that a display is installed on the rearview mirror (Fig. not shown), the
但是,后视镜上加装倒车影像显示器显示摄影状况,虽然能辅助驾驶观视的死角问题,不过却也因为窗框12与镜面部位13两者的穿透率与反射率上的差异,导致于正常反射显示后方影像下,窗框12的部位特别阴暗,且若窗框12与镜面部位13若差异过大,甚至反而让驾驶者感到不利观测后方动态,造成视觉混淆。However, installing a reversing image display on the rearview mirror to display the shooting situation, although it can assist the driver to view the blind spot problem, is also caused by the difference in the transmittance and reflectivity between the

具体实施方式 Detailed ways
下面结合附图及实施例对本实用新型进行详细说明:Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:
参阅图2及图3,本实用新型具有显示单元的后视镜第一个较佳实施例,包括有一个壳体2、一装设于该壳体2的镜片组3,及一个设置在该壳体2内的显示单元4。Referring to Fig. 2 and Fig. 3, the first preferred embodiment of the utility model has the rearview mirror of display unit, comprises a
该壳体2具有一个开口部21。The
该镜片组3装设在该开口部21,且该壳体2与该镜片组3间产生有一个安装区间5,该显示单元4装设于该安装区间5内,且发光面是对应于该镜片组3。The
该镜片组3整体成型为10~40%穿透率且40%以上反射率的均匀镜体。该镜片组3具有一个对应于该显示单元4发光面的第一显示区域31,及一个有别于该第一显示区域31的第二显示区域32,且该第一显示区域31与该第二显示区域32具有相同的穿透率与反射率。The
该显示单元4的亮度需配合该镜片组3穿透率的需求控制,较佳的是让穿透过该镜片组3后的亮度在100CD/M2以上,即以穿透率40%的镜片组3而言,该显示单元4最低的亮度输出需在250CD/M2以上,借此,该显示单元4用于显示倒车影像、字幕字符或图案等拨放,才足以让驾驶者便于观视。The brightness of the
此外,该镜片组3整体达成10~40%穿透率及40%以上反射率的方式颇多,较佳的方式有金属膜或金属氧化物膜成型法、光触媒反应膜、物理气相沉积法,或化学气相沉积法等。其中最常见的是金属膜或金属氧化物膜成型法,如透过氧化还原镀膜、金属溅镀、蒸着镀膜、真空电镀等方式达成。In addition, there are many methods for the
参阅图4,本较佳实施例的一种镜片组3组成,该镜片组3具有一个玻璃基板33,及至少一个膜层34。该膜层34可以镀着于该玻璃基板33一侧或二侧,包括一个多层型态金属镀层341,并直接产生预定的穿透率与反射率。Referring to FIG. 4 , a lens set 3 of this preferred embodiment is composed. The
参阅图5,本实用新型第二个较佳实施例,该镜片组3还具有一个有效控制可见光的滤光层342,并同该金属膜层341使镜片组3达到预定的穿透率与反射率。Referring to Fig. 5, the second preferred embodiment of the utility model, the
参阅图6,本实用新型第三个较佳实施例,该镜片组3还具有一个以贴着方式贴覆其上的增亮膜343,例如采用3M公司所产制的Vikuiti光学增亮膜,借以提高该显示单元4穿透后的亮度,且该增亮膜343并同该金属膜层341使镜片组3达到预定的穿透率与反射率。Referring to Fig. 6, the third preferred embodiment of the utility model, the
参阅图7,本实用新型第四个较佳实施例,该镜片组3的增亮膜343并同该金属膜层341、该滤光层342,使镜片组3达到预定的穿透率与反射率。Referring to Fig. 7, the fourth preferred embodiment of the utility model, the
参阅图8,本实用新型的第五个较佳实施例,该镜片组3是透过光触媒反应成型,该镜片组3具有一个玻璃基板33,及至少一个膜层35。该膜层35包括一个氧化物多层膜351,涂布该玻璃基板33的一侧或二侧,且通常选自于二氧化硅(SiO2)或二氧化钛(TiO2)作为主原料,并直接产生预定的穿透率与反射率。此外,该膜层35除了以氧化物多层膜351达成穿透率与反射率外,还可配合如图5、6、7揭示的该滤光层342、该增亮膜343等方式并合达成。Referring to FIG. 8 , the fifth preferred embodiment of the present invention, the
参阅图9,本实用新型的第六个较佳实施例,该镜片组3具有至少二个玻璃基板33,及至少二个分别对应镀着于所述玻璃基板33上的膜层36、37,该膜层36、37得以镀着于所述玻璃基板33一侧或二侧,该膜层36、37可以为如同前述的金属镀层34或氧化物多层膜35,且所述膜层36、37配合二个玻璃基板33用以产生预定的穿透率与反射率。此外,还可配合前述的该滤光层342、该增亮膜343等方式并合达成预定的穿透率与反射率。Referring to Fig. 9, the sixth preferred embodiment of the present utility model, the
值得一提的是,透过各种镀膜技术或薄膜成型技术大凡都得以取得预定的穿透率与反射率,无论使用物理方式或化学方式的基板着膜,若膜厚越厚相对于穿透率就会较低而反射率就越高,相反的,膜厚越薄穿透率就会较高而反射率就越低,其次,控制穿透率及反射率除了膜厚关系外,尚有主原料的粒子较具影响性,例如镀铬、镀银相同的膜厚就会有不同的反射率与穿透率产生,而举凡镀膜技术种类因非属本实用新型所诉求重点,就不再详细说明,且上述的镀膜成型只是较常见的做法,举凡相关的薄膜成型方式皆仍属本实用新型专利涵盖的范围内。It is worth mentioning that the predetermined transmittance and reflectance can generally be obtained through various coating technologies or thin film forming technologies. Regardless of the use of physical or chemical substrate coating, the thicker the film thickness relative to the transmittance It will be lower and the reflectance will be higher. Conversely, the thinner the film thickness will be, the higher the transmittance will be and the lower the reflectance will be. Secondly, besides the relationship between film thickness, there are still main factors to control the transmittance and reflectance. The particles of raw materials are more influential. For example, the same film thickness of chrome plating and silver plating will have different reflectivity and transmittance. However, the types of coating techniques are not the focus of this utility model, so they will not be described in detail. , and the above-mentioned coating forming is only a relatively common method, and all related film forming methods are still within the scope covered by the utility model patent.
再者,上述诸较佳实施例都是以镀膜技术直接达成,但是于目前实务上,还可利用电致变色的原理,以导电方式改变镜片组的穿透率与反射率而达到预定目的。即该镜片组上以二玻璃基板镀上对应的膜层,但是穿透率与反射率并没有在指定的区间,若于玻璃基板上增加一个正负极的导电层,于该导电层通电下将使整个镜片组穿透率与反射率改变,而符合所需的穿透率与反射率。目前现有技术已存在二个玻璃基板间镀上金属层配合数金属氧化物层,然后于其上填充固态或液态的正负极导电元素,将导电元素通电后,将可使整体产生电致反应而达成需求。由于电致变色的技术手段并非本实用新型诉求的重点,相关技术在此不再详细加说明。Furthermore, the above-mentioned preferred embodiments are directly achieved by coating technology, but in current practice, the principle of electrochromism can also be used to change the transmittance and reflectance of the lens group in a conductive manner to achieve the predetermined purpose. That is to say, the corresponding film layer is coated on the two glass substrates on the lens group, but the transmittance and reflectivity are not in the specified range. If a positive and negative conductive layer is added to the glass substrate, the conductive layer will The transmittance and reflectance of the entire lens group will be changed to meet the required transmittance and reflectance. At present, in the existing technology, a metal layer is coated with a number of metal oxide layers between two glass substrates, and then solid or liquid positive and negative conductive elements are filled on it. After the conductive elements are energized, the whole will generate electro- respond to needs. Since the technical means of electrochromism is not the focus of the utility model, the relevant technologies will not be described in detail here.
使用时,参阅图2、图3,当该显示单元4作动下,得以穿透第一显示区域31显示出,当该显示单元4不作动时,第一显示区域31及第二显示区域32可以完整的反射后视状况。When in use, referring to Fig. 2 and Fig. 3, when the
借此,可以避免传统镜片组3上因为需要高穿透率而产生的窗框,使得该显示单元4显示与整体后视镜镜片组3的反射显示,都能让驾驶者观测下不产生视觉混淆。综上所述,本实用新型具有显示单元的后视镜确实能达成预其的使用目的。In this way, it is possible to avoid the window frame on the traditional lens set 3 due to the need for high transmittance, so that the display of the
