Description

一种汽车座椅加热垫
技术领域
本发明涉及汽车座椅技术领域,更具体地说,涉及一种汽车座椅加热垫。
背景技术
近年来,随着汽车领域的快速发展和普及,人们对于车内环境,特别是新车内部的气味影响的关注也越来越重视。新车内部的气味主要来源于车身内饰件的诸如甲醛、苯等挥发性有机化合物 VOC ( volatile organic compounds )的影响,诸如车内塑料构件、座椅发泡体、内饰布料及导体线束等构件。由此气味方面的问题引起的纠纷已经多有发生,尤其在炎热的夏季,由于车内气味高温挥发引起的投诉尤为突出。
改善车内由挥发性有机化合物 VOC 引起的不良气味的方法,更多的是在要求各个零部件厂商在相关部件的挥发性有机化合物 VOC 验证上尽可能符合相关要求,以求整车内部的气味性降低到客户满意。此方式虽然降低了新车内部的气味,然而,相关零部件中各种材质的有机助剂使用无法避免,由此却无助于在现有情况下的进一步的气味改善。
现有技术中的一个解决方案是在座椅的透气面套内部设置具有活性炭材料的 VOC 吸附材料的消滤结构体。采用具有活性炭材料的 VOC 吸附材料结构可以有效地吸附座椅及车辆内部由挥发性有机化合物 VOC 引起的不良气味,改善车内空气环境。
然而在物理学上,由于多孔隙的活性炭材料具有对外部细微粒子的吸附饱和特性,使得当具有活性炭材料的 VOC 吸附材料的消滤结构体经过一定的时间后,内部的活性炭会趋近于吸附饱和状态,进而逐步失去对车内挥发性有机化合物 VOC 的消滤功能。
因此,如何实现对吸附饱和活性炭的脱附再生,恢复消滤结构体的 VOC 吸附功能,是本领域技术人员目前需要解决的技术问题。
发明内容
有鉴于此,本发明提供了一种汽车座椅加热垫,以实现对吸附饱和活性炭的脱附再生,恢复消滤结构体的 VOC 吸附功能。
