在下文描述中，探讨了大量细节，以提供对本申请实施例的更透彻的解释，然而，对本领域技术人员来说，可以在没有这些具体细节的情况下实施本申请的实施例。在下文实施例中，以方框图的形式示出公知的结构和设备，以避免使本申请的实施例难以理解。
传统座椅无法提供个性化的脊柱矫正支持，进而导致驾驶场景中，驾驶员和乘客在长时间乘坐过程中，容易产生不正确的坐姿，进而对脊柱造成伤害。在办公场景中，长时间坐在办公座椅上的工作人员也容易产生不正确的坐姿，进而对脊柱造成伤害。本申请用于解决传统座椅无法提供个性化的脊柱矫正支持，导致人们在长时间乘坐过程中容易产生不正确的坐姿，进而对脊柱造成伤害的技术问题。下面以车载脊柱矫正座椅为例来描述本申请的实施例。
请参阅图1，本申请提供的车载脊柱矫正座椅，包括：座椅本体1，座椅本体1包括坐垫11、靠背12、头枕13和腰托14，坐垫11、靠背12、头枕13和腰托14之间可调节安装；以及红外扫描装置2，红外扫描装置2包括若干组红外扫描点21，红外扫描点21安装在靠背12上且位于与乘客背部相对应的靠背12的侧面，以对乘客的脊柱进行扫描；以及数据处理装置3，数据处理装置3分别与红外扫描装置2、坐垫11、靠背12、头枕13和腰托14电连接，以根据扫描得到的脊柱的形态对坐垫11、靠背12、头枕13和腰托14进行相应的坐姿调整。红外扫描装置2可以是红外扫描仪，数据处理装置3可以是一个或者多个处理器。
通过上述内容不难发现，座椅本体1可以为驾驶位驾驶员座椅也可以为副驾或后排座椅。乘客在乘坐车辆座椅的过程中，乘客的背部会对应于靠背12上的红外扫描装置2。通过红外扫描装置2布置在靠背12上的多个红外扫描点21扫描乘客背部中间区域的脊柱。再通过利用仿真技术，以精准捕捉人体后背的三维图像，自动识别出脊柱所处的形态。针对脊柱所处的形态，在脊柱形态超出标准形态时，通过数据处理装置3控制靠背12、头枕13和腰托14，并进行对应的调节。从而在通过分别对靠背12、头枕13和腰托14的调节后，可以实现人体脊柱形态能够保持在标准形态范围内，从而矫正坐姿。其中，红外扫描点21位于乘客倚靠的靠背12的侧面，以方便乘客落座后对其背部进行脊椎的扫描。在靠背12、头枕13和腰托14进行调节时，各部分的调节方式与脊椎形态的矫正方式相对应。例如，在对靠背12进行调节时，为了实现对脊柱侧弯角的矫正，靠背12会朝向纠正脊柱侧弯角的方向进行调整，例如脊柱侧弯角为朝向座椅本体1左侧或右侧形成侧弯角时，则会对靠背12向右或向左调整，脊柱侧弯角为朝向座椅本体1后侧形成侧弯角时，则会对靠背12向前调整。在对头枕13进行调节时，当检测出胸曲角超出标准形态时，则会控制对头枕13的前后调节。在腰托14进行调节时，可根据腰曲角的弯曲角度、骨盆旋转角的旋转角度和骨盆倾斜角的倾斜角度，对腰托14进行与弯曲角度、旋转角度、倾斜角度相反方向的矫正调节。通过上述利用座椅对脊柱进行矫正，以实现通过无辐射的扫描乘客的脊柱，准确测出脊柱所处形态，从而根据脊柱所处形态对座椅的靠背12、头枕13和腰托14进行分别调节，以保证乘客乘坐座椅时的脊柱形态保持在标准形态范围内，使乘客无损伤乘坐座椅。
如图1所示，座椅还包括：安装在座椅本体1上的开关按钮4，开关按钮4与红外扫描装置2电连接，以控制红外扫描装置2开启或关闭。
在本申请一实施例中，该开关按钮4可以安装在靠背12上，或者也可以安装在座椅的其他方便手部触摸的区域，以通过按下开关按钮4启动红外扫描装置2工作，通过红外扫描点21对人体背部的脊柱进行扫描。
同样的，也还可以通过遥控器或车机等将控制信号发送给红外扫描装置2，以实现对红外扫描装置2的开启控制。
红外扫描点21沿乘客背部的脊柱的长度方向布置有若干组，且每组中的红外扫描点21分布于乘客背部的脊柱的两侧。
在本申请一实施例中，在对乘客脊柱进行扫描时，为了保证对人体脊柱沿其长度方向进行扫描，红外扫描点21沿着脊柱长度方向布置。并且为了更好的测出脊柱左右两侧的形态，红外扫描点21分布在脊柱的左右两侧。例如，红外扫描点21由4个组成，其中，沿脊柱长度方向上分布有两行红外扫描点21，且每行红外扫描点21为两个。每行的红外扫描点21形成扇形的扫描区间并对应于脊柱的长度方向，由对应列的扇形的扫描区间构成对脊柱左右两侧的扫描。
作为本发明的一种可选实施例，驾驶员或是乘客上车后，长按开关按钮3秒启动，然后红外扫描点21开始工作，会进行20秒的扫描。然后数据处理装置3在得道扫描数据后即刻生成三维图像并分析脊柱形态，接着会在30秒内根据乘客情况，自动调节头枕13、腰托14和靠背12的角度等。
如图2所示，本申请实施例提供的数据处理装置3包括：脊柱扫描单元5，被配置为控制红外扫描装置2采集脊柱的扫描数据，例如脊柱扫描单元5可以控制红外扫描装置2的开启和关闭，或者配置红外扫描装置2的工作周期；数据计算单元6，被配置为根据扫描数据，确定出脊柱各区域的弯曲程度；以及座椅调节单元7，与数据计算单元6通信连接，被配置为判断脊柱各区域的弯曲程度是否满足各区域相应的预定要求，若不满足预定要求时，则控制对头枕13、腰托14和靠背12进行相应调整，以矫正脊柱。
在本申请一实施例中，在对脊柱进行扫描、弯曲程度测定和座椅调节时，通过脊柱扫描单元5可以利用红外扫描点21扫描背部，采集到扫描数据，并将扫描数据传输给数据计算单元6。数据计算单元6在获取到扫描数据后，可以对脊柱对应的各个区域进行弯曲程度的计算。在计算得到脊柱各个区域弯曲程度后，数据计算单元6可以将脊柱各个区域弯曲程度传输给座椅调节单元7。通过座椅调节单元7判断确定各区域的弯曲程度是否超出各区域对应设置的预定要求，若超出预定要求，则说明背部脊柱需要进行矫正，则根据弯曲程度超出预设要求的程度，来实现对座椅的控制调整。从而可以通过座椅的调整来实现对乘客的脊柱形态的矫正，从而保证了乘客的乘坐姿势，并减少脊柱损伤。
如图3所示，数据计算单元6包括存储库61以及比对分析模块62。架构存储库61将标准脊柱的形态存储在人体数据库架构。比对分析模块62将扫描数据对应的脊柱形态与人体数据库架构中的标准脊柱的形态进行比对，确定当前的脊柱相对应标准脊柱的弯曲程度。
在本发明一实施例中，数据计算单元6在确定脊柱的弯曲程度时，通过利用架构存储库61可以实现对由标准脊柱组成的人体数据库架构进行存储。并且在扫描脊柱得到脊柱的扫描数据时，通过比对分析模块62可以实现自动的将脊柱的扫描数据与标准脊柱进行对比分析，确定出扫描数据对应的脊柱与标准脊柱之间的区别，并确定出扫描数据对应的脊柱相对于标准脊柱的弯曲程度。
进一步的，比对分析模块62包括分区对比模块621以及弯曲程度测算模块622。分区对比模块621将扫描数据对应的脊柱各区域的三维图像与标准脊柱各对应区域的三维图像进行分别的形态比对。弯曲程度测算模块622测算出脊柱各区域相对于标准脊柱各对应区域的弯曲角度。
在本申请一实施例中，在确定扫描数据对应的脊柱相对于标准脊柱的弯曲程度时，根据脊柱各个区域的不同，产生变形对应的座椅调节方式也不同。因此，在进行对比分析时，需要进行脊柱各区域的分别比对分析。具体的，通过分区对比模块621可以实现在扫描脊柱得到脊柱各区域的三维图像后，将扫描数据对应的脊柱各区域的三维图像与标准脊柱各对应区域的三维图像进行分别的形态比对。再通过弯曲程度测算模块622可以实现扫描数据对应脊柱各区域相对于标准脊柱的弯曲角度计算。也就是说，该脊柱各区域相对于标准脊柱各对应区域的弯曲角度为扫描数据对应脊柱的弯曲角超出标准脊柱的标准弯曲角的角度范围的部分。
值得注意的是，扫描得到的脊柱为通过红外扫描点21初步扫描得到的脊柱部分区域的三维图像，并在数据计算单元6将扫描数据与标准脊柱的形态比对计算，进而得到此扫描脊柱对应的标准化下且包括脊柱所有区域在内的脊柱的三维图像。再将该包括脊柱所有区域在内的脊柱的三维图像与标准脊柱的弯曲程度进行比较。
弯曲角度包括脊柱侧弯角度、胸曲角度、腰曲角度、骨盆旋转角度和骨盆倾斜角度。
在本申请一实施例中，脊柱侧弯角度为整体形态的侧弯角度，即脊柱原本为笔直形态，在落座时会形成向左或向右的侧弯。胸曲、腰曲和骨盆沿脊柱高度方向至上而下依次布置。从而以实现根据脊柱侧弯角度情况对靠背12进行调节，根据胸曲角度情况对头枕13进行调整。根据腰曲角度、骨盆旋转角度和骨盆倾斜角度情况对腰托14进行高度、角度和位置的调整。
如图4所示，座椅调节单元7包括数据输出模块71以及调节控制模块72。数据输出模块71输出判断脊柱各区域的弯曲程度不满足各区域相应的预定要求时的判断信号。调节控制模块72基于判断信号，控制对相应区域的座椅进行减弱弯曲程度的负向调节。
在本申请一实施例中，在根据脊柱的弯曲程度对座椅进行调节时，数据输出模块71可以在脊柱各区域的弯曲程度不满足各区域相应的预设要求时，向调节控制模块72输出该不满足条件下的判断信号。根据该判断信号，调节控制模块72对座椅产生该判断信号所在的区域进行减弱该弯曲程度的调节控制，以实现对脊柱的对应区域的矫正。
进一步的，调节控制模块72包括：靠背调节模块721、头枕调节模块722以及腰托调节模块723。靠背调节模块721基于脊柱侧弯角度与标准脊柱侧弯角度之间的第一角度差和弯曲方向，对靠背12进行相反方向、与第一角度差相同角度的调节。头枕调节模块722基于胸曲角度与标准胸曲角度之间的第二角度差和弯曲方向，对头枕13进行相反方向、与第二角度差相同角度的调节。腰托调节模块723被配置为分别基于腰曲角度与标准腰曲角度之间的第三角度差和弯曲方向、骨盆旋转角度与标准骨盆旋转角度之间的第四角度差和弯曲方向、骨盆倾斜角度与标准骨盆倾斜角度之间的第五角度差和弯曲方向，对所述腰托14分别进行相反方向、与所述第三角度差、第四角度差和第五角度差相同角度的调节。所述相反方向为减弱或者增大弯曲的方向。例如，当扫描的弯曲角度大于标准脊柱的角度，则相反方向为减弱弯曲的方向；当扫描的弯曲角度小于标准脊柱的角度，则相反方向为增大弯曲的方向。
在本申请一实施例中，在对座椅进行控制调节时，靠背调节模块721可以在脊柱侧弯角度与标准脊柱侧弯角的第一角度差超出预定要求时，控制靠背12朝向弯曲的相反方向进行调节，从而可以矫正脊柱侧弯角，使脊柱侧弯角保持在标准形态的脊柱侧弯角范围内。头枕调节模块722可以在胸曲角度与标准胸曲角度的第二角度差超出预定要求时，控制头枕13朝着减弱该胸曲角的相反方向进行调节，以矫正胸曲角并使胸曲角保持在标准形态对应的胸曲角范围内。腰托调节模块723在腰曲角度、骨盆旋转角度和骨盆倾斜角度分别超出预定要求的第三角度差、第四角度差和第五角度差时，则控制腰托14朝向减弱腰曲角、骨盆旋转角和骨盆倾斜角的相反方向进行调节，以矫正腰曲角、骨盆旋转角和骨盆倾斜角，并使腰曲角、骨盆旋转角和骨盆倾斜角保持在标准形态对应的腰曲角、骨盆旋转角和骨盆倾斜角范围内。
其中，第一角度差为扫描得到的脊柱的脊柱侧弯角与标准脊柱的脊柱侧弯角的差值。第二角度差为扫描得到的脊柱的胸曲角与标准脊柱的胸曲角的差值。第三角度差为扫描得到的脊柱在腰曲角超出标准脊柱的腰曲角的差值。第四角度差为骨盆旋转角超出标准脊柱的骨盆旋转角。第五角度差为骨盆倾斜角超出标准脊柱的骨盆倾斜角时的角度差值。
具体的，在脊柱侧弯角进行矫正时，对应调整靠背12的角度。例如，当脊柱检测出左侧弯大于标准脊柱的脊柱侧弯角5度，靠背调节模块721控制靠背12的背角向右调整5度；在脊柱向后侧弯大于标准脊柱的脊柱侧弯角3度，靠背调节模块721控制对靠背12背角向前调整3度。在对胸曲角进行矫正时，对应调整头枕13的角度。例如，当脊柱检测出胸曲角大于标准脊柱的胸曲角2度时，头枕调节模块722控制头枕13向后调整2度。在对腰曲角、骨盆旋转角和骨盆倾斜角进行矫正时，对应调整腰托14的角度。例如，检测出腰曲角、骨盆旋转角度和骨盆倾斜角度的第三角度差、第四角度差和第五角度差，根据第三角度差、第四角度差和第五角度差，腰托调节模块723则控制等值调整腰托14高度、角度和位置。
请参阅图5，人体的脊柱由颈曲、胸曲、腰曲和骶曲组成，并且胸曲对应着胸曲角，腰曲对应着腰曲角，骶曲对应着骨盆旋转角和骨盆倾斜角。整个脊柱则对应着脊柱侧弯角。其中，在进行座椅调节时，通过靠背调节模块721以实现对脊柱侧弯角进行矫正，通过头枕调节模块722对胸曲角进行矫正，通过腰托调节模块723对腰曲角、骨盆旋转角和骨盆倾斜角进行调整。
请参阅图6，图6示出了盆骨顶部的三组分别为“正常”、“后倾”和“前倾”的侧面视角。在盆骨为“正常”形态下，盆骨顶部的圆弧状位于中间位置，而在盆骨“后倾”时，盆骨顶部的圆弧状则向左侧偏移，在盆骨“前倾”时，则盆骨顶部的圆弧状向右侧偏移。骨盆倾斜角为骨盆前倾或者后倾的倾斜角度。图6还示出了盆骨底部的四组为盆骨左右高度不一和盆骨向左/右旋转的正面视角。其中，盆骨左右高度不一的情况下，会出现左低右高或左高右低。在盆骨向左/右旋转的情况下，会出现盆骨的顺时针偏转和盆骨的逆时针偏转。骨盆旋转角为盆骨左右旋转的角度。
通过腰托调节模块723对腰曲角、骨盆旋转角和骨盆倾斜角进行调整具体为，当腰曲角度大于标准脊柱的腰曲角度3度时，调节腰托14整体向后移动至腰曲角度等于标准脊柱的腰曲角度；当骨盆倾斜角大于标准脊柱的骨盆倾斜角，例如前倾5度时，调节腰托14向后旋转5度；当骨盆旋转角度为左低右高，例如向左旋转3度时，调节腰托14向右旋转3度。
请参阅图7为脊柱发生侧弯时对应的形态，即对应于脊柱侧弯角。其中，最左侧图片示出脊柱侧弯时脊柱形成的“C”形状，中间图片示出脊柱侧弯时脊柱形成的“S”形状，最右侧图片示出正常形态下的脊柱形状，对应于标准脊柱的形态。
如图8所示，本申请进一步提供了车载脊柱矫正方法，包括如下步骤：
S1：利用红外扫描装置采集对脊柱的扫描数据；
S2：根据扫描数据，确定出脊柱各区域的弯曲程度；以及
S3：判断脊柱各区域的弯曲程度是否满足各区域相应的预定要求，若不满足预定要求时，则控制对座椅进行调整，以矫正脊柱。
在本申请一实施例中，在对脊柱通过座椅调节进行矫正时，根据红外扫描点21对人体脊柱的扫描，以获取到脊柱的扫描数据。并且通过该扫描数据，对脊柱各区域，即包括脊柱侧弯角、胸曲角、腰曲角、盆骨旋转角和盆骨倾斜角进行弯曲程度的测算。并且通过判断该弯曲程度是否超出标准脊柱对应于的各区域的预定要求。以实现在不满足预定要求时，对脊柱各区域对应的座椅的靠背12、头枕13和腰托14分别进行调节，以使脊柱各区域矫正至标准形态下，以实现在乘坐汽车座椅时对人体脊柱的保护。
综上所述，本申请通过红外扫描装置2和其包括的红外扫描点21在靠背12上的布置，可以实现通过红外技术对乘客的脊柱进行无辐射的扫描，并准确的测量出脊柱的弯曲程度。并且在测量脊柱的弯曲程度时，通过测算扫描得到的脊柱相对于标准形态下的脊柱的弯曲程度是否超出标准脊柱对应的预定要求，可以确定是否对脊柱通过座椅调节进行矫正。并且在进行座椅调节时，通过对脊柱对应的各区域，如脊柱侧弯角、胸曲角、腰曲角、盆骨旋转角和盆骨倾斜角的测算，可以实现对座椅本体1的坐垫11、靠背12、头枕13和腰托14进行分区域的调节，从而使调整后的靠背12角度、头枕13角度和腰托14角度，能够提供适合乘客脊柱的乘坐姿势，降低了乘坐汽车座椅时对脊柱造成的伤害，进而可以提供符合人体工程学且无损伤矫正坐姿的乘坐体验。所以，本申请有效克服了一些座椅中的种种缺点而具高度产业利用价值。
上述实施例仅例示性说明本申请的原理及其功效，而非用于限制本申请。任何熟悉此技术的人士皆可在不违背本申请的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本申请所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本申请的权利要求所涵盖。

  13. 根据权利要求12所述的脊柱矫正方法，其中，基于所述判断信号，控制对相应所述区域的所述座椅进行减弱所述弯曲程度的负向调节，包括：
    基于脊柱侧弯角度与标准脊柱侧弯角度之间的第一角度差和弯曲方向，对靠背(12)进行相反方向、与所述第一角度差相同角度的调节；
    基于胸曲角度与标准胸曲角度之间的第二角度差和弯曲方向，对头枕(13)进行相反方向、与所述第二角度差相同角度的调节；以及
    分别基于腰曲角度与标准腰曲角度之间的第三角度差和弯曲方向、骨盆旋转角度与标准骨盆旋转角度之间的第四角度差和弯曲方向、骨盆倾斜角度与标准骨盆倾斜角度之间的第五角度差和弯曲方向，对所述腰托(14)分别进行相反方向、与所述第三角度差、第四角度差和第五角度差相同角度的调节。
  14. 一种数据处理装置，应用于座椅，包括：
    脊柱扫描单元(5)，被配置为控制所述红外扫描装置(2)采集所述脊柱的扫描数据；
    数据计算单元(6)，被配置为根据所述扫描数据，确定出所述脊柱各区域的弯曲程度；以及
    座椅调节单元(7)，被配置为判断所述脊柱各区域的所述弯曲程度是否满足各区域相应的预定要求，若不满足所述预定要求时，则控制对所述座椅进行调整，以矫正所述脊柱。
