【专利文献1】特开2012－244614号公报
【发明内容】
【本发明要解决的技术问题】
就安装在车辆上的行车记录仪而言，由于其相机组件直接安装在车辆上，因此容易因运行时的振动或冲击产生抖动，很可能出现图像不清晰的情况。

【具体实施方式】
下文将参照图纸，说明本发明的实施方式。而且，以下实施方式以本发明的两轴倾斜装置、照相装置以及电子设备为例进行说明，本发明并非意图限定于以下实施方式。
如图1所示，作为本实施方式的电子设备的行车记录仪10具有照相装置和安装部件500。照相装置具有作为被倾斜部件的相机组件100，以及通过两轴使相机组件100倾斜的两轴倾斜装置。相机组件100上连接着电源线400。两轴倾斜装置具有在相机组件100的周围将其包围的框架体200、连接相机组件100和框架体200的4个悬架弹簧300、分别为悬架弹簧300供应电流的电流供应控制组件(未进行图示)。
相机组件100形成长方体形状的箱体。相机组件100具有在X-Y平面方向扩展的大体为正方形的前面110、相对于前面110平行的底面120，以及4个侧面130A～130D(未特别区分的时候，统称为“侧面130”)。前面110与底面120大体形状相同，尺寸相同。前面110、底面120也可采用长方形或圆形。4个侧面130A～130D大体是尺寸相同的长方形，分别在Z轴方向具有规定的高度，在Y轴方向或者X轴方向具有规定的长度。侧面130A、130B在Y-Z平面方向扩展，侧面130C、130D在X－Z平面方向扩展。
相机组件100的前面110上配置着以Z轴方向为光轴的透镜140。而且，在相机组件100的内部，相对于透镜140平行地配置着通过该透镜140接收来自被摄体的光的摄像元件(未进行图示)。而且，在相机组件100的内部，设计了分别为悬架弹簧300提供电流的电流供应控制组件。进而，也可设计存放SD卡等存储媒介的存储媒介存放部(未进行图示)，或者处理摄像元件拍摄的图像存储在存储媒介的图像控制组件(未进行图示)。
框架体200包括背面侧框架体210、框架体侧板220。背面侧框架体210包括在X-Y平面方向扩展的矩形的背面板211，以及从背面板211的周围沿着Z轴方向延伸的4个背面侧板212A～212D。背面板211的尺寸比所述相机组件100的底面120大。换言之，背面板211的X轴方向长度、Y轴方向长度比底面120的X轴方向长度、Y轴方向长度大。
框架体侧板220在相机组件100的周围将其包围，Z轴方向两侧是敞开的中空方柱部，包括4个框架体侧板220A～220D。框架体侧板220A～220B的Y轴方向长度、框架体侧板220C、220D的X轴方向长度分别等于背面侧板212A、212B的Y轴方向长度、背面侧板VC、212D的X轴方向长度，而且比相机组件100的侧面130A、130B的Y轴方向长度、侧面130C、130D的X轴方向长度大。因此，当相机组件100配置在框架体200内时，各侧面130A～130D分别相对于各框架体侧板220A～220D隔开一定空间无接触地相向而对。
4个悬架弹簧300配置在相机组件100的底面120与框架体200的背面板211之间，将两者连接起来。4个悬架弹簧300在底面120的中心轴周围等间隔(90度间隔)地循环配置。在本实施方式中，在X轴方向配置2个(悬架弹簧300A、300B)、在Y轴方向配置2个(悬架弹簧300C、300D)。悬架弹簧300A配置在底面120的接近侧面130A部位的Y轴方向中央，悬架弹簧300B配置在底面120的接近侧面130B部位的Y轴方向中央。悬架弹簧300C配置在底面120的接近侧面130C部位的X轴方向中央，悬架弹簧300D配置在底面120的接近侧面130D部位的X轴方向中央。
也可将4个悬架弹簧300配置在相机组件100的底面120的四角附近。而且，本发明不限定于配置4个悬架弹簧300，只要在底面120的中心轴周围，等间隔地排列、循环配置至少3个悬架弹簧300即可。
如图3所示，对于各个悬架弹簧300，从整体来看，其具有背面板侧端部301、相机组件侧端部302，在背面板侧端部301和相机组件侧端部302之间形成弹簧本体部303。各个悬架弹簧300通过在正中间将形状记忆合金制的金属丝310翻折缠绕成螺旋状而制成。该金属丝310的中央部分311在整个悬架弹簧300的一端侧(即背面板侧端部301)通过翻折形成翻折部312。换言之，弹簧本体部303的形成螺旋状的第1弹簧本体部303A与第2弹簧本体部303B在同一轴上组合。翻折部312相对于背面板211平行延伸为直线状，联结第1弹簧本体部303A与第2弹簧本体部303B。金属丝310的两端部313位于整个悬架弹簧300的另一端侧(即相机组件侧端部302)。分别将第1弹簧本体部303A的端部与第2弹簧本体部303B的端部向Z方向翻折形成两端部313。两端部313最好设置在将螺旋的中心夹在中间的两相反侧。
金属丝310的两端部313固定在相机组件100的底面120上，与相机组件100内部的电流供应控制组件(未进行图示)电气连接。另一方面，翻折部312固定在背板面211上。因此，悬架弹簧300仅从电流供应控制组件供应控制电流，无需从背面侧框架体210侧供应电流。就金属丝310而言，除了两端部312外，其最好均被绝缘材料覆盖。
如图2所示，相机组件100的底面120连接着电源线400。电源线400为存放在相机组件100的电流供应控制组件、存储媒介存放部、图像控制组件供应电源。背面侧板212B和背面板211形成切口部230。该切口部230是用于拉出电源线400的导出口。
如图1、图2所示，安装部件500具有棒材510、固定部件520。棒材510的一端510A固定在框架体200上，比如固定在框架体侧板220D上。棒材510的另一端510B上形成球体510C。固定部件520具有固定板521和圆筒部522，前者具有粘贴在车辆前玻璃上的粘贴面，后者在该粘贴面的相反侧凸出。圆柱部522和球体510C构成所谓的球联结器，由圆柱部522支撑着，将球体510C包进去，棒材510获得支撑后，能够以一定的自由度相对于固定部件520调整方向和角度。
下文将对上述本实施方式的行车记录仪10的组装例进行说明。将电源线400以及悬架弹簧300的相机组件侧端部302连接在相机组件100的底面120。在此种情况下，在X轴方向排列配置的悬架弹簧300A、300B的翻折部312沿着X轴方向延伸配置。同样，在Y轴方向排列配置的悬架弹簧300C、300D的翻折部312沿着Y轴方向延伸配置。随后，将悬架弹簧300的背面板侧端部301连接背面板211。由此，相机组件100处于通过悬架弹簧300被框架体200悬架着的状态。
随后，将相机组件100插入框架体侧板220内。而且相对于背面侧框架体210安装框架体侧板220。具体地，将框架体侧板220A～220D的Z轴方向的后端与背面侧框架体210的背面侧板212A～212D的Z轴方向的前端对接\固定。在此种情况下，电源线400通过背面侧框架体210的切口部230被拉出框架体200的外部。由此，相机组件100处于可在框架体200的内部倾斜的状态。
进而，将安装部件500的棒材510的一端510A固定连接在框架体200的框架体侧板220之一上(图1、图2中为框架体侧板220D)，将另一端510B的球体510C插入固定部件520的圆柱部件522内。
接着将对本实施方式的行车记录仪10的动作进行说明。例如，事先分别从电流供应控制组件向4个悬架弹簧300供应规定的电流。增加流向在X轴方向排列的悬架弹簧300A的电流，减少流向悬架弹簧300B的电流。于是，悬架弹簧300A沿着Z轴方向收缩，相机组件100被拉近框架体200的背面板211侧。而且，另一个悬架弹簧300B沿着Z轴方向延伸，相机组件100离开框架体200的背面板211侧。结果在相机组件100上产生绕着Y轴周围的旋转(在图2中为逆时针旋转)。
如将电流方向反过来，使悬架弹簧300A延长，使悬架弹簧300B收缩，则在相机组件100上产生绕着Y轴周围的顺时针旋转。
同样，如给在Y轴方向排列的2个悬架弹簧300C、300D施加同样的电流控制，则可在相机组件100上产生绕着X轴周围的旋转。由此可实现在相机组件100上绕着X轴周围、Y轴周围旋转。
而且，也可以不事先供应规定的电流，而是向使其收缩的悬架弹簧300提供必要的电流使其收缩，从而在相机组件100上产生旋转。
相机组件100的电流供应控制组件具有角速度检测元件(未进行图示)。车辆运行期间的振动或冲击传递至相机组件100，通过角速度检测元件检测出每个X轴周围成分、Y轴周围成分。电流供应控制组件根据检测出的X轴以及/或者Y轴周围成分的角速度的大小和方向，分别向悬架弹簧300A～300D提供电流，使其伸长/收缩、或者收缩。由此，使相机组件100在X轴周围以及/或者Y轴周围倾斜，返回原来的方向。由此，相机组件100与车里的摇晃阻断。
而且，悬架弹簧300也可配置金属丝310的两端部313作为背面板侧端部301，配置翻折部312作为相机组件侧端部302。而且，也可将金属丝310的一侧端部313作为背面板侧端部301固定在背面板211上，将另一侧端部313作为相机组件侧端部302固定在相机组件100的底面120上。在此种情况下，弹簧本体部303仅形成1个螺旋形状。所述实施方式对将本发明适用于行车记录仪的例子进行了说明，但是本发明的适用对象并不限于行车记录仪，还可适用于搭载在自行车或无人机上的照相装置等。
