具体实施方式
为使本公开技术方案和优点更加清楚，下面将结合附图及具体实施例进行 详细描述。
本公开具体实施例所述安全座椅，包括底座和椅背，其中所述椅背包括形状可调节的骨架和包覆于所述骨架外部的由柔性材料制成的包覆件，当骨架的形状改变时，包覆与骨架外部的包覆件的形状也相应的改变；所述包覆件表面设置有多个传感器，用于感应获得所乘坐人员的背部位置信息；
所述安全座椅还包括：
数据处理装置，用于接收每一所述传感器所获得的背部位置信息，确定所乘坐人员的背部表面形状，发出包覆件调整信号；
驱动结构，用于根据所述包覆件调整信号调整所述骨架的形状，使得通过所述骨架形状的改变，改变所述包覆件的表面形状，与所乘坐人员的背部表面形状相适配。
本公开实施例所述安全座椅，通过包覆件表面设置的传感器，可以探测获得所乘坐人员的背部位置信息，以进一步确定背部表面形状，自动调节包覆件的形状形成与所乘坐人员的背部表面形状相适应的形状，满足所乘坐人员的舒适度要求。
图1为本公开具体实施例所述安全座椅的结构侧视示意图。如图1所示，安全座椅包括底座10和椅背20，椅背20包括形状可调节的骨架21和包覆于骨架21外部的由柔性材料制成的包覆件22；其中包覆件22表面设置有多个传感器，用于感应获得所乘坐人员的背部位置信息。
其中，本公开实施例中，如图1所示，能够实现椅背20形状可调节的骨架21由多个支撑杆211拼接构成，且相邻支撑杆之间转动连接。另外，各个支撑杆211均与一驱动结构连接，通过调整相邻支撑杆之间所呈角度，调整骨架的形状。
具体地，如图2所示，骨架21由多个水平排列的第一支撑杆组和多个竖直排列的第二支撑杆组构成，其中每一第一支撑杆组包括多个水平设置的支撑杆211，每一第二支撑杆组包括多个竖直设置的支撑杆211，各个水平设置的 支撑杆211和各个竖直设置的支撑杆211之间交错排列为网状，且任意相邻的支撑杆211之间转动连接。通过这种设置方式，当需要调整包覆件22的表面形状时，只需要改变各个支撑杆211之间所呈角度即可。
具体地，所述驱动结构可以包括一驱动电机，各个支撑杆211可以分别通过一连接支杆与驱动电机连接，驱动电机通过驱动连接支杆移动，使连接支杆带动相应的支撑杆211移动，进而改变所述移动的支撑杆211与其所连接支撑杆211之间所呈角度。在本公开一实施例的安全座椅中，如图8所示的安全座椅椅背的俯视图中，所述驱动结构包括多个成阵列排布的驱动电机322，所述椅背设置有成阵列排布的出传感器321，每一个传感器321对应于一个相邻支撑杆的连接点且对应于一个驱动电机322，每一个相邻支撑杆的连接点通过一对应的连接支杆323与对应的驱动电机322连接，所述驱动结构驱动一个或多个驱动电机322，通过对应的连接支杆322带动对应的相邻支撑杆的连接点移动，以改变相邻支撑杆之间的角度。
当然，上述能够实现包覆件22的表面形状改变的骨架结构，仅为本公开的一种实施例，具体并不仅限于该种结构形式。
本公开实施例所述安全座椅中，设置于包覆件22表面的多个传感器可以为压力传感器，包覆件22表面的平面图如图3所示，包覆件22表面均匀分设有多个压力传感器221，用于感应安全座椅上所乘坐人员的背部在包覆件22上的压力以获得对应的压力信号，也即各个压力传感器221所获得的背部位置信息包括对应于所乘坐人员的背部在包覆件上的压力的压力信号。
设置于安全座椅上的数据处理装置，用于接收每一压力传感器221所获得的背部位置信息，也即压力信号，确定所乘坐人员的背部表面形状，进而发出包覆件调整信号。
本公开实施例中所述数据处理装置具体包括：
第一信号接收器，用于采集每一压力传感器221发出的压力信号；
第一分析器，用于根据每一压力传感器221发出的压力信号的压力值，确 定所乘坐人员的背部表面形状。
上述的第一分析器，将各个压力传感器221所发出压力信号的压力值进行比较，当其中一压力信号的压力值较大时，则确定发出该压力信号的压力传感器221相对应的背部位置处较为突出，因此在包覆件22上的压力较大；当其中一压力信号的压力值较小时，则确定发出该压力信号的压力传感器221相对应的背部位置较为凹陷，因此在包覆件上的压力较小。基于该原理，第一分析器根据每一压力传感器221所发出压力信号的压力值，能够确定所乘坐人员的背部表面形状。
进一步地，该数据处理装置还可以包括：
第二分析器，用于根据所述第一分析器所确定的乘坐人员的背部表面形状，确定所乘坐人员在包覆件22上的背部轮廓区域；
第三分析器，用于在驱动结构根据包覆件调整信号调整骨架21的形状之后，再次接收位于包覆件22上背部轮廓区域内的每一压力传感器221检测获得的压力信号，判断每一压力传感器221发出压力信号的压力值与预定压力值的差值是否在预设范围内；
第一信号发送器，用于当第三分析器的判断出所述包覆件22上所述背部轮廓区域内每一压力传感器221发出的压力信号的压力值与所述预定压力值的差值都在预设范围内时，向驱动结构发出调整停止信号；当第三分析器判断出所述包覆件22上所述背部轮廓区域内至少有一个压力传感器221发出的压力信号的压力值与所述预定压力值的差值没有在所述预设范围内时，向驱动结构发出调整继续信号。
本公开实施例中，数据处理装置利用上述的第二分析器分析确定乘坐人员在包覆件22上的背部轮廓区域，也即在包覆件22上的抵靠范围；利用第三分析器在驱动结构根据包覆件调整信号进行骨架21的形状调整之后，对背部轮廓区域内的每一压力传感器221检测获得的压力信号进行判断，与预定压力值进行比较，若每一压力传感器221发出的压力信号的压力值与所述预定压力值 的差值在所述预设范围之内，则说明乘坐人员背部的每一位置在包覆件上的压力相当，每一位置都均匀压设在包覆件上，包覆件22的表面形状与背部的表面形状相适配，此时可以向驱动结构发出调整停止信号；若背部轮廓区域内的至少一个压力传感器221所发出压力信号的压力值与所述预定压力值的差值没有在所述预设范围之内，则说明乘坐人员背部的至少一个位置在包覆件上的压力不同于所述乘坐人员背部的其他位置在包覆件上的压力，即所述乘坐人员的背部并非所有位置都均匀压设在包覆件上，包覆件22的表面形状与背部的表面形状不相适配，需要向驱动结构发出调整继续信号，直至包覆件22上背部轮廓区域内每一压力传感器221上所采集压力信号的压力值与所述预定压力值的差值都在所述预设范围之内，包覆件22的表面形状与背部的表面形状相适配。
基于上述的结构和原理，当包覆件22的表面设置压力传感器时，能够通过数据处理装置确定所乘坐人员的背部表面形状，发出包覆件调整信号。
包括上述第一信号接收器、第一分析器、第二分析器和第三分析器的数据处理装置，可以集成设置于椅背20上，也可以集成设置于底座10上，或者形成为多部件的结构形式，一部分部件设置于椅背20上，一部分部件设置于底座10上。具体地，无论设置于椅背20上，还是设置于底座10上，或是部分设置于椅背20上部分设置于底座10上，数据处理装置的设置以不影响乘坐和保证美观性为重要考虑要素。
如图4，当本公开实施例所述安全座椅的椅背20上设置压力传感器时，根据所乘坐人员的背部表面形状自动调节背靠形状的流程包括：
第一信号接收器采集每一压力传感器221发出的压力信号；
第一分析器根据每一压力传感器221发出的压力信号的压力值，确定所乘坐人员的背部表面形状并发出包覆件调整信号；
第二分析器根据所乘坐人员的背部表面形状，确定所述乘坐人员在包覆件22上的背部轮廓区域；
驱动结构根据所述包覆件调整信号调整骨架21的形状；
第三分析器在驱动结构根据包覆件调整信号调整骨架21的形状之后，再次接收位于包覆件22上背部轮廓区域内的每一压力传感器221检测获得的压力信号，判断每一压力传感器221发出的压力信号的压力值与预定压力值的差值是否在预设范围内；
当第三分析器判断出所述包覆件22上所述背部轮廓区域内每一压力传感器221发出压力信号的压力值与所述预定压力值的差值都在预设范围内时，第一信号发送器向驱动结构发出调整停止信号；当第三分析器判断出所述包覆件22上所述背部轮廓区域内至少有一个压力传感器221发出的压力信号的压力值与所述预定压力值的差值没有在所述预设范围内时，第一信号发送器向驱动结构发出调整继续信号。
本公开另一实施例的安全座椅中，设置于包覆件22表面上的传感器也可以为位置传感器。包覆件22的平面图可以参阅图5所示，包覆件22表面均匀设有多个位置传感器222，用于感应安全座椅上所乘坐人员的背部相对于包覆件22表面垂直距离而获得对应的距离信号，也即各个位置传感器222所获得的背部位置信息包括对应于所乘坐人员的背部表面相对于包覆件22表面垂直距离的距离信号。
具体地，位置传感器222可以为电磁波或红外光线式，通过发送电磁波或红外光线测量包覆件22的表面上位置传感器222的安装点到所乘坐人员背部的垂直距离，数据处理装置根据每一位置传感器222上所获得的距离信号，确定所乘坐人员的背部表面形状，发出包覆件调整信号。
较佳地，结合图5和图1，数据处理装置具体包括：
第二信号接收器，用于采集每一所述位置传感器获得的距离信号；
第四分析器，用于根据每一所述位置传感器获得的距离信号的距离值，确定所乘坐人员的背部表面形状；
第五分析器，用于根据所乘坐人员的背部表面形状，确定所述乘坐人员在 包覆件22上的背部轮廓区域；
第六分析器，用于在驱动结构根据包覆件调整信号调整骨架21的形状之后，接收位于包覆件22上背部轮廓区域内的每一位置传感器222检测获得的距离信号，判断位于包覆件22上背部轮廓区域内每一位置传感器222所获得距离信号的距离值与预定距离值的差值是否在预设范围内；
第二信号发送器，用于当第六分析器判断出位于包覆件22上背部轮廓区域内每一位置传感器222所获得距离信号的距离值与所述预定距离值的差值都在所述预设范围内时，向驱动结构发出调整停止信号；当第六分析器判断出包覆件22上背部轮廓区域内至少有一个位置传感器222所获得距离信号的距离值与所述预定距离值的差值不在所述预设范围内时，向驱动结构发出调整继续信号。
上述实施例所述安全座椅的数据处理装置，利用上述的第五分析器分析确定乘坐人员在包覆件22上的背部轮廓区域，也即在包覆件22上的抵靠范围；利用第六分析器在驱动结构根据包覆件调整信号进行骨架21的形状调整之后，对背部轮廓区域内的每一位置传感器222检测获得的距离信号进行判断，与所述预定距离值进行比较，若每一位置传感器222上的距离信号的距离值与所述预定距离值的差值在所述预设范围内，如每一位置传感器222获得的距离信号的距离值均为零，或每一位置传感器222获得的距离信号的距离值与预定距离值零的差值都在所述预设范围内，则说明乘坐人员背部的每一位置与包覆件22表面的距离相等，包覆件22的表面形状与背部的表面形状相适配，此时可以向驱动结构发出调整停止信号；若包覆件22上背部轮廓区域内至少有一个位置传感器222获得的距离信号的距离值与所述预定距离值的差值不在所述预设范围内，则说明包覆件22的表面形状与背部的表面形状不相适配，需要向驱动结构发出调整继续信号，直至包覆件22上背部轮廓区域内每一位置传感器222所获得的距离信号的距离值与所述预定距离值的差值都在所述预设范围内，此时包覆件22的表面形状与背部的表面形状相适配。
基于上述的结构和原理，当包覆件22的表面设置位置传感器时，能够通过数据处理装置确定所乘坐人员的背部表面形状，发出包覆件调整信号。
如图6，当本公开实施例所述安全座椅的椅背20上设置位置传感器时，根据所乘坐人员的背部表面形状自动调节背靠形状的流程包括：

当第六分析器判断出位于包覆件22上背部轮廓区域内每一位置传感器222所获得距离信号的距离值与所述预定距离值的差值都在所述预设范围内时，第二信号发送器向驱动结构发出调整停止信号；当第六分析器判断出包覆件22上背部轮廓区域内至少有一个位置传感器222所获得距离信号的距离值与所述预定距离值的差值不在所述预设范围内时，第二信号发送器向驱动结构发出调整继续信号。
