Description

一种人体压力传感器、汽车座椅、汽车及人体压力传感器的加工方法
相关申请的交叉引用
本申请要求于2017年05月18日提交中国专利局的申请号为2017103504649、名称为“一种人体压力传感器及汽车座椅”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及汽车座椅技术领域，更具体地说，涉及一种人体压力传感器、汽车座椅、汽车及人体压力传感器的加工方法。
背景技术
随着车辆交通领域的科技发展，座椅使用者监测作为乘员安全带提醒领域的应用要求，越来越得到市场的重视。
一种设置在座椅坐垫下方的人体压力传感器，采用压力开关元件通过座椅坐垫，对来自椅面的人体压力的存在进行检测，可以有效地感知座椅使用者的存在，实现使用者存在探测的功能。上述人体压力传感器是压力开关产品的一个简单应用，就是将一个压力开关元件及配合结构，布置于车辆座椅内部坐垫发泡垫下方的承载骨架上。当人体臀部压力作用到座椅海绵承载垫的椅面时，人体重量施压在此人体压力开关上，进而触发相应箔式压力开关元件的传感触点，使之产生通断特性的电路输出特征。该人体压力传感器通常由传感器单元、线束、以及连接器等部件构成。
现有技术中，具备上述人体压力传感器的汽车座椅结构包括采用由钢丝拉筋构成的弹簧骨架结构、与海绵垫体为基材的坐垫，以及相关附件构成的座部总成。上述人体压力传感器设置在该座部总成中，其位于弹簧骨架结构与坐垫二者的结合区域。
在以往的工程设计过程中，人体压力传感器中的开关电路通常采用类似薄膜开关的特征设置。即，开关电路由上下两层的导电薄膜构成的压力传感单元，作为乘员人体承压开关探测单元。然而这种设计结构，往往需要采用较为复杂的薄膜开关与外部导电线的塑胶连接方式，其空间占用大、开关灵敏性不好，还有抗折损性差和成本高的缺点。
同时，当前应用在汽车座椅的人体压力传感器常常需要在压力开关回路中，设置串并联电阻、二极管、电容、TVS抗浪涌保护元器件等外围电子元器件。在现有技术中，通常采用以聚酯薄膜为基材的柔性薄膜开关电路，这样柔性薄膜开关电路很难以简单经济地布置和制造上述外围电子元器件。

图1为本发明实施例提供的第一种人体压力传感器的结构示意图；图2为本发明实施例提供的第二种人体压力传感器的结构示意图；图3为本发明实施例提供的第三种人体压力传感器的结构示意图；图4为本发明实施例提供的第四种人体压力传感器的结构示意图；图5为本发明实施例提供的人体压力传感器受力时的结构示意图(图中示出了图2中的人体压力传感器受力时的示意图)；图6为本发明实施例的硬式印刷电路板的结构示意图。
请参阅图1-图4、图6。从图中可以看出，本发明实施例提供的人体压力传感器包括硬式印刷电路板102、柔性聚酯薄膜104、承载底板101和压触顶盖106。其中，硬式印刷电路板102上设置有并行排布的两个裸露金属膜触点103(如图6所示)及导电回路。
柔性聚酯薄膜104上设置有箔式导电层1041，且其和硬式印刷电路板102之间设置有 弹性间隔层105,于裸露金属膜触点103处，弹性间隔层105开设有供箔式导电层1041在触压作用下与裸露金属膜触点103接触的贯通孔洞，以接通并行排布的两个裸露金属膜触点103。
进一步的，该并行排布的两个裸露金属膜触点103处，为弹性间隔层105的贯通孔洞。与该弹性间隔层105的贯通孔洞相对应，设置在柔性聚酯薄膜104上的箔式导电层1041。即弹性间隔层105在压力传感点的位置设置有贯通孔洞，贯通孔洞的一侧是硬式印刷电路板102的裸露金属膜触点103；贯通孔洞的另一侧是柔性聚酯薄膜104的箔式导电层1041。
硬式印刷电路板102设置于承载底板101上。箔式导电层1041、弹性间隔层105和硬式印刷电路板102设置于由压触顶盖106和承载底板101组成的包容体内。可选地，，压触顶盖106上设置有向裸露金属膜触点103方向凸出的凸出结构1061(如图1所示)，以保证人体压力传感器的灵敏性。
硬式印刷电路板102通过导电金属连接物与外部的电连接器构成电气关联；该导电金属连接物为金属插针(如图1所示)、导电卡子或导线焊接体(如图2-4所示)。进一步的，硬式印刷电路板102具有与裸露金属膜触点103电连接的金属针状接线端子107(金属针状接线端子107与裸露金属膜触点103连接形成了焊接点1031),金属针状接线端子107用于与外部的电连接器构成电气关联。
承载底板101在金属针状接线端子107穿出的区域，设置有与承载底板101为同一结构体的遮护套108(如图1所示)。金属针状接线端子107和遮护套108构成电连接器，如此有利于方便地与外部导线束的对接电连接器相汇接。
本发明提供的人体压力传感器，当座椅受到乘员人体乘坐时，承接来自海绵承载垫一侧的乘员压力，使得柔性聚酯薄膜104上的箔式导电层1041向硬式印刷电路板102的裸露金属膜触点103趋近，直至相互接触，构成电气接触回路，达到提醒乘客的作用。本发明将硬式印刷电路板102上的裸露金属膜触点103替代传统的导电薄膜，相较于现有的薄膜开关与外部导电线的连接方式，这样的人体压力传感器的硬式印刷电路板102与外部导电线的连接方式更加方便，且具有空间占用小、开关灵敏性好、抗折损性好和成本低的优点。另一方面，这样的人体压力传感器的硬式印刷电路板102更容易设置串并联电阻、二极管、电容、TVS抗浪涌保护元器件等外围电子元器件。即硬式印刷电路板102可以设置外围电子元器件，外围电子元器件为电阻110(图6中示出)、电容、电感和/或TVS抗浪涌保护元器件。
在本发明一具体实施例中，箔式导电层1041为贴附在柔性聚酯薄膜104上的金属箔层，或者为印刷在柔性聚酯薄膜104上的导电油墨层。当带有箔式导电层1041的柔性聚酯薄膜104,受到来自于上部的压力时，柔性聚酯薄膜104向下凹陷。并透过弹性间隔层105的贯 通孔洞，接触到硬式基材的具有承压特征的硬式印刷电路板102。此时，柔性聚酯薄膜104的箔式导电层1041，触碰到硬式印刷电路板102上设置的并行的电路排布的裸露金属膜触点103,构成电气接触回路。
在本发明一具体实施例中，金属针状接线端子107为由硬式印刷电路板102穿越承载底板101向下的直式金属插针(如图1所示)，或者为穿越承载底板101横向引出的直角金属弯针；金属针状接线端子107与硬式印刷电路板102的连接，为焊接方式或插接方式。
在本发明一具体实施例中，弹性间隔层105为具有双面胶黏特征的聚酯薄膜间隔体，或者具有厚膜印刷图案粘合特征的绝缘间隔油墨层，或者为弹性橡塑薄层。弹性间隔层105具有设定厚度的尺寸特征，使得间隔硬式印刷电路板102的裸露金属膜触点103与柔性聚酯薄膜104的箔式导电层1041保持预设的距离。
在本发明一具体实施例中，硬式印刷电路板102的硬式基材为酚醛基材、玻纤环氧基材或棉质环氧基材；可选地，硬式印刷电路板102可以为单层电路板，也可为多层电路板。
在本发明一具体实施例中，承载底板101为平板状结构或者为向上围起的盒体式容留结构；压触顶盖106为平板状结构或者为向下围起的盒体式容留结构。这里需要说明的是，图1中示出了压触顶盖106为平板状结构；图2-图4示出了压触顶盖106为向下围起的盒体式容留结构，而承载底板101为平板状结构的情形。
在本发明一具体实施例中，压触顶盖106与柔性聚酯薄膜104之间设置有弹性垫层111(图1-图4均示出)。
硬式印刷电路板102经过粘贴、卡接、穿孔熔焊或者扣盖限位的方式固定在承载底板101上。
这里需要说明的是，图6还示出了连接裸露金属膜触点103的导电线路112。
图7为本发明实施例提供的人体压力传感器所处位置的俯视图；图8为本发明实施例提供的人体压力传感器所处位置的正视图。
本发明实施例还公开了一种汽车座椅，包括海绵承载垫和支撑骨架，其中，还包括如上实施例公开的人体压力传感器100，人体压力传感器100设置于海绵承载垫和支撑骨架之间。承载底板101可经过卡接或挂接的方式，设置在支撑骨架上。
请参阅图7和图8,在本发明一具体实施例中，人体压力传感器100的至少一个传感触点位于预设区域内，该预设区域位于海绵承载垫前端面起与靠背骨架转轴200之间，居于海绵承载垫前方的三分之一至二分之一的距离区域范围内，且沿海绵承载垫的中轴线对称布置(如图8所示)。
且该预设区域的宽度W0为海绵承载垫宽度W的四分之一，即预设区域一侧距离海绵承载垫的中轴线的距离W1，与预设区域另一侧距离海绵承载垫的中轴线的距离W2相等，且均为W0的一半(如图8所示)。
需要说明的是，人体压力传感器100设置的区域不限于上述的位置，这里仅仅是一个示例。
图9为本实施例提供的汽车座椅300的结构图示意图，图10为图9另一个视角的结构示意图。请参照图9和图10，从图中可以看出，汽车座椅300包括相互连接的坐垫310和靠背320，以及设置在坐垫310中的人体压力传感器100。
人体压力传感器100设置在坐垫310宽度方向轴线的两侧的任一位置；人体压力传感器100位于坐垫310长度方向的中轴线，且远离靠背320方向的三分之一至二分之一的距离区域范围内。
需要说明的是，图9和图10均示出了人体压力传感器100设置在坐垫310宽度方向轴线的两侧的两种设置方式，在使用时，汽车座椅300的坐垫310中设置一个人体压力传感器100即可。
进一步地，从图中还可以看出，坐垫310包括包裹层、钢丝拉筋311和托挂结构体312。钢丝拉筋311设置在托挂结构体312以提供弹性支撑。包裹层(如上述的海绵承载垫)包裹钢丝拉筋311和托挂结构体312以为用户提供柔软的支撑面，同时还起到保护用户的身体与坐垫310内部结构的缓冲部。人体压力传感器100设置在托挂结构体312中的钢丝拉筋311的间隙之间，且人体压力传感器100被包裹层包围。如此，人体压力传感器100设置方便，不占用坐垫310的额外空间，经济效益显著。
本发明实施例还公开了一种汽车，其包括上述任一项的汽车座椅。
本发明实施例还公开了一种人体压力传感器的加工方法，该人体压力传感器的加工方法用于加工上述的人体压力传感器100；加工方法包括以下步骤：

柔性聚酯薄膜104上设置箔式导电层1041，使箔式导电层1041位于裸露金属膜触点103上方；在箔式导电层1041位于裸露金属膜触点103之间设置弹性间隔层105；在弹性间隔层(105上开设有供箔式导电层1041在触压作用下与裸露金属膜触点(103接触的贯通孔洞，以接通并行排布的两个裸露金属膜触点103。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
