 本发明的实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本实用新型保护的范围。
图1是本实用新型植绒式缓冲泡沫结构示意图。如图1所示，一种植绒式缓冲泡沫，包括缓冲层，所述缓冲层包括依次叠置设置的缓冲泡沫层1，胶结层2，植绒功能层3，所述胶结层2用于胶结所述缓冲泡沫层1和植绒功能层3。具体实施时，缓冲泡沫层包括聚苯乙烯泡沫、聚丙烯泡沫、醋酸乙烯类泡沫中的的任意一种或者多种混合。所述植绒功能层3包括纤维材料，其厚度可以根据需要设置为300～900μm ,例如可以设为900μm、500μm、300μm等。所述纤维材料包括聚酯纤维、尼龙纤维、锦纶纤维中的的任意一种或者多种混合。为了提升胶结层2其粘贴性，胶结层厚度可以根据需要设为100～500微米。为了提升缓冲泡沫层1的缓冲舒适度，可以根据需要将缓冲泡沫层1厚度设为12～30毫米。为了防止植绒式缓冲泡沫内部受潮，可以根据需要在植绒功能层3上粘连防潮层4。
可以通过以下方法对该缓冲泡沫进行制作：
（1）采用白电油等将缓冲泡沫洗净，去除脱模剂；
（2）采用水性胶黏剂，用喷涂方式均匀附着在缓冲泡沫上；
（3）利用静电吸附原理，将所需不同功能、尺寸的短纤维吸附在胶黏剂上；
（4）加热处理使其固化；
（5）利用压缩空气将未粘附上的纤维吹净，从而获得粘结牢固的植绒式泡沫。
以下具体来说明本实用新型植绒式缓冲泡沫的制备过程：
实施例1
（1）用干净的聚酯布吸附白电油将聚苯乙烯泡沫洗净，去除脱模剂；
（2）采用水性聚丙烯酸胶黏剂，用喷涂方式均匀附着在缓冲泡沫上，喷涂厚度在900μm；
（3）利用静电吸附原理，将0.7mm长度的带有抗菌剂的微纳米孔洞的聚酯纤维通过风道吸附在水性聚丙烯酸胶黏剂上；
（4）放置在烘箱中，调温至80℃，烘烤10小时，使其固化；
（5）利用压缩空气将未粘附上的纤维吹净，从而获得粘结牢固的抗菌、阻燃植绒式泡沫。
实施例2
（1）用干净的聚酯布吸附白电油将聚丙烯泡沫洗净，去除脱模剂；
（2）采用水性聚氨酯胶黏剂，用喷涂方式均匀附着在缓冲泡沫上，喷涂厚度在500μm；
（3）利用静电吸附原理，将0.9mm长度的混有石蜡基相变材料的锦纶纤维通过风道吸附在水性聚氨酯胶黏剂上；
（4）放置在烘箱中，调温至60℃，烘烤12小时，使其固化；
（5）利用压缩空气将未粘附上的纤维吹净，从而获得粘结牢固的可储热的植绒式泡沫。
实施例3
（1）用干净的聚酯布吸附白电油将聚苯乙烯泡沫洗净，去除脱模剂；
（2）采用水性聚丙烯酸胶黏剂，用喷涂方式均匀附着在缓冲泡沫上，喷涂厚度在300μm；
（3）利用静电吸附原理，将0.5mm长度的具有微纳米孔洞的中空聚酯纤维通过风道吸附在水性聚丙烯酸胶黏剂上；
（4）放置在烘箱中，调温至80℃，烘烤6小时，使其固化；
（5）利用压缩空气将未粘附上的纤维吹净，从而获得粘结牢固的易吸汗的植绒式泡沫。
植绒是利用电荷同性相斥异性相吸的物理特性，使绒毛带上负电荷，把需要植绒的物体放在零电位或接地条件下，绒毛受到异电位被植物体的吸引，呈垂直状加速飞升到需要植绒的物体表面上，由于被植物体涂有胶粘剂，绒毛就被垂直粘在被植物体上，从而使产品展现强烈的立体感、颜色鲜艳、手感柔和、豪华高贵等特征。由此可见，本实用新型植绒式缓冲泡沫将原本没有采用植绒工艺的泡沫赋予了良好外观的特性，使之更为美观，且保护了泡沫不易受外界损坏；
本实用新型植绒式缓冲泡沫通过将不同功能的短纤维进行附着，使原本只有防冲击功能的泡沫具有了其他特性，增加了产品的附加值。
本实用新型一实施例还提供了一种头盔，包括上述实施例的植绒式缓冲泡沫。
由上述说明可知，使用根据本实用新型的植绒式缓冲泡沫及头盔，一方面可以增加头戴式设备整体的美观程度；另一方面通过增加缓冲层的功能性，如储热、吸汗、抗菌、阻燃等，来提升头戴式设备的舒适程度，更加提升了用户的使用满意度，可广泛适用于头戴式设备中。
 工业实用性
以上对本实用新型实施例进行了详细介绍，本文中应用了具体个例对本实用新型的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本实用新型的方法及其核心思想；同时，对于本领域的一般技术人员，依据本实用新型的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本实用新型的限制。
