Description

用于防护服的快速充抽气装置和包括该装置的智能多用途防护服 技术领域
本发明涉及一种用于防护服的充抽气装置以及包括智能控制该充抽气装置的防护服，该防护服在具有普通服装的保温御寒、通风散热特性下，快速调整服装内气压。
背景技术
滑雪、驾驶摩托车、赛车以及高空作业等由于其速度和高度而具有固有的危险性。为了防止或至少减轻高速碰撞或者高空跌落对人员造成的损伤，提出了可快速调整服饰内气压的防护服。
该防护服可以根据御寒、工作方便需要调整服装内的气压膨胀状况，危险情况下可智能快速充气加压，由此，为人员提供缓冲保护。但是，目前的防护服存在一些问题，例如，充气装置通常由爆炸装置或者压缩气体装置构成，由此，在发生危险时，快速释放大量气体，使得防护服被充满气体而膨胀，从而产生缓冲屏障。但是，这些充气装置通常是一次性的，即，在充气膨胀之后充气装置无法恢复，使得防护服无法恢复到原来的状态，只能被抛弃。这对于经常需要穿戴防护服的人员来说，构成很大的成本。
另外，也提出了一些设置气泵来充气的防护服，但是，这些防护服通常依靠抽气阀来释放被充入的气体，因此，抽气过程很慢，并且很难将充入的气体完全排出。这就给防护服的收藏带来麻烦。
另外，在目前的防护服设计中，由于气囊无序地排布在防护服内，使得防护服比较臃肿，使得即使在气囊未充气的情况下，穿着防护服的人员的动作笨拙。
发明内容
因此，本发明的目的是提供一种用于防护服的充抽气装置。利用根据本发明的充抽气装置，可以快速对防护服进行充气和抽气，并且可以多次重复使用，另外，可以将防护服内的气体完全排出，使得防护服可以多次使用， 并且也便于防护服的收藏和穿戴。
另外，提供了一种包括上述充抽气装置的防护服，该防护服在充气状态下可以保护穿着者的安全，并且在抽气释压状态下，防护服可以如同普通衣服一样，不会妨碍穿着者的运动，同时抽真空状态下便于收藏。
另外，由于本发明具有真空排气功能，故可自由地在各气室内填充如羽绒类的蓬松隔热保温材料，在气压的调整下，可避免使用者过分臃肿、动作笨拙，又能实现最小体积的收藏。
根据本发明的一个方面，提供了一种充抽气装置，其包括外筒，在所述外筒上设置有第一孔；内筒，所述内筒设置在所述外筒内并设置有第二孔且能够在第一位置和第二位置之间滑动，在所述第一位置，所述第二孔与所述第一孔对准，而在所述第二位置，所述第二孔与第一孔偏离开并且被所述外筒的内壁所封闭；设置在所述内筒中的叶片和驱动叶片的电机；将所述内筒朝向所述第一位置偏压的偏压装置；其中，所述内筒还包括第三开口，并且所述第三开口上设置有单向阀，以仅允许加压气体从内筒经过第三开口向外侧流动，而阻止加压气体相反方向的流动。
根据本发明的另一方面，提供了一种包括上述充抽气装置的防护服。
利用本发明的防护服，可以快速充气以达到防护目的，并且在使用结束后可以快速抽气，以将防护服恢复到平整状态，便于收藏。这种可多次使用的防护服，降低了使用者的成本。
根据本发明的第二实施例，由于本发明的核心-快速充抽气装置可以实现大风量快速充气、抽气，且体积小，可以在服装的重要部位预先设置多个，同时，相应的获得更大的气压，另外，通过增加叶片增压级数量，可以获得更高的气压。
优选地是，本发明还包括传感器，如图像传感器或距离传感器，以感测防护服的使用者距障碍物的距离，并与上述充抽气装置结合，实现对使用者的主动保护。该图像传感器或距离传感器，例如，类似于汽车自动驾驶中采用的传感器，可以实现快速接近障碍物的预警反应，从而触发充抽气装置，并通过多级叶片的快速高压充气，实现高级别的安全防护，以抵御可能的风险。

下面参照附图，详细描述根据本发明的优选实施方式的充抽气装置以及包括该充抽气装置的防护服。要指出的是，该描述仅仅出于举例说明的目的而非限制，并且，本领域技术人员将明白本发明可以以多种方式来实施，而不应局限于在此描述的优选实施方式。
另外要指出的是，在下面的描述中以及在所附的权利要求中，“上游或上游方向”是指在充抽气装置处于充气的工作状态下气体源自的方向，而“下游或下游方向”是指在充抽气装置处于充气的工作状态下，气体所流向的方向。
首先参照图1，图1是示出根据本发明的优选实施例的充抽气装置的分解透视图。如图1所示，该充抽气装置100包括外筒1以及可滑动地安装在外筒1内的内筒2，内筒2分成两个部分，即，叶片容纳部分21和电机容纳部分22，并且在内筒的叶片容纳部分21的下游端部上设置有阀23。在所述内筒的叶片容纳部分21内可旋转地设置有叶片3，该叶片3优选地为多级叶片，以便将进气加压到较高的压力，在所述电机容纳部分22内，设置有电机4，该电机4优选地为可双向旋转的可逆电机。所述外筒1的上游端部还设置有端盖6，端盖例如螺纹连接到外筒1上，并且端盖6上设置有孔，以允许电机4的电线穿过，并允许空气被吸入并阻挡较大的异物。在内筒2，具体地说，内筒2的电机容纳部分22的上游端部和端盖6之间，设置有偏压弹簧5，该偏压弹簧5将内筒2朝向下游方向上偏压。
其中，外筒1在其下游端部处开放，并且内筒2在其上游端部的端面中可以开设有多个孔24，以允许气体通过。外筒1在其圆周上设置有多个孔11，该孔11例如为方形孔。与外筒1的开孔11相对应，内筒1在其圆周上也设置多个孔25，所述孔25的形状例如与外筒1上的孔11的形状相同，且所述孔11和25以相同的间隔设置，优选地是，开孔11和开孔25都围绕圆周方向等间隔设置。
在内筒2的下游端部处，设置了阀23，如图1所示，该阀23为膜片状，包括阀主体232和从阀主体232的圆周位置延伸的腿部231，并且阀23利用该腿部231固定到内筒2的下游端部的端面上。优选地，沿圆周方向设置有多个腿部(图中示出3个)。
如图1所示，在外筒1的大致中间位置处，设置有导引狭槽12，该导引狭槽12优选地设置有多于一个，例如，两个、三个或更多个，并沿圆周方向均匀间隔开。在内筒2的相对应位置处设置有相应的销孔26，以接收导引销(未示出)。
在装配时，内筒2插入到外筒1内，并且导引销穿过导引狭槽12插入到销孔26内并固定于内筒2上。由此，内筒2可以在导引狭槽12的引导下在外筒1内滑动。
如图1所示，该导引狭槽12优选地设置成与外筒1的纵向轴线倾斜，并可以具有一定的曲率，由此，在内筒2沿着导引狭槽12滑动过程中，内筒2不仅进行沿着外筒1的纵向轴线的平移运动，而且进行围绕纵向轴线的转动运动。
导引狭槽12的两端构成内筒2的两个止挡位置。具体地说，当导引销处于导引狭槽12的下游端部时，内筒2处于下游位置，其圆周方向上的孔25与外筒1的圆周方向的孔11相互对准的位置，而当导引销处于导引狭槽12的上游端部时，内筒2处于上游位置，内筒2的孔25与外筒1的孔11不对准并且内筒2的孔25被外筒1的筒壁封闭。
在内筒2的上游端部和外筒1的上游端部处的端盖6之间设置有弹簧5，该弹簧将内筒2朝向下游方向偏压，即朝向下游位置偏压。
如图1至5所示，叶片3采用三级叶片，即，沿着从上游到下游的方向，包括第一直径叶片31、第二直径叶片32和第三直径叶片33，第一直径大于 第二直径，且第二直径大于第三直径，由此，可以将气体逐渐增压。另外，上述三级叶片仅是示例性的，也可以根据不同的需要设置更多或更少的叶片，以提供所需的更高的气压。
如图2至5所示，内筒2的叶片容纳部分21包括变直径的内腔，所述叶片3的第二直径叶片32和第三直径叶片33容纳在该内腔中，并且内腔的尺寸基本上对应于第二直径和第三直径叶片的尺寸，使得内腔包裹这两级叶片。这有利于将气体加压到更高的压力。
在内筒2的电机容纳部分22内，设置有驱动叶片的电机4，该电机4是可逆电机，并且，其导线从端盖6引出，以连接到控制电路(未示出)。孔25形成在电机容纳部分22的圆周上并在大致对应于第一直径叶片31的纵向位置。
下面，参照图2至5，简要描述根据本发明的优选实施方式的充抽气装置的工作方式。下面的描述以该充抽气装置处于防护服中的情况下加以介绍，但是要理解的是，该充抽气装置可以用于各种需要充抽气的目标中，本发明并不局限于此。
如图2至5所示，在弹簧4的作用下，内筒2被偏压到下游位置，内筒2的孔25与外筒1的孔12对准，此时，风机4被供能，由此空气被从端盖6吸入，并且经三级叶片3增压而充入目标内。具体地说，被第一直径叶片31加压的空气中的一部分通过对准的孔25和12注入到目标，例如防护服的内腔中，另一部分加压空气被第二直径叶片32和第三直径叶片33继续加压，并推开阀23，从内筒2的下游端部充入防护内。随着防护服内的空气的压力增大，该空气的作用力相应地增大，从而将阀23的阀主体232向内筒2的下游端部的端面上压，并同时克服弹簧5的偏压力而将内筒2朝向上游方向移动。由此，内筒2在导引狭槽12的引导下移动并转动，直到导引销抵靠导引狭槽12的上游端部为止，此时，内筒2的孔25被外筒1的筒壁所遮挡，空气无法通过孔25和孔11提供到目标内。此时，空气进一步通过第二直径叶片32和第三直径叶片33增压，并在空气的压力大于防护服内的压力时，顶开阀23，通过内筒2的下游端部继续向防护服充气，如图3所示。
随着防护服内的空气的压力增大，当防护服内的空气压力与通过叶片3增压的空气压力达到平衡时，阀23的阀主体232被压在内筒2的下游端部 的端面上，此时，进入保压状态。优选地是，设置有传感器(未示出)，例如，压力传感器，以在达到该状态时，断开电机4的供电。
优选地是，在导引狭槽12的上游端部处，设置有沿圆周方向延伸的止停段121，当内筒2由于防护服内的空气压力被朝向上游方向推动到上游位置时，由于内筒2沿着倾斜的导引狭槽12的转动的惯性，导引销落入该止停段121内。
在需要抽气的情况下，风机3在与充气时的方向相反的方向上旋转，在叶片3开始转动的瞬时转矩带动下，内筒2也随着叶片3一同转动，由此使得导引销从止停段121中转出，并且在叶片3的抽气作用下以及在弹簧5的弹性作用下，内筒2向下游方向移动，同时，导引销沿着导引狭槽12滑动，开孔12和25逐渐重合，最终到达如图5所示的抽气位置，在该位置，开孔12和25完全重合，由此，从防护服中快速抽出全部气体。
优选地是，还设置有另一传感器，以在气体被抽出之后自动停止电机4的操作。或者，可以人工操作，以手动关闭电机4。
由于采用了三级叶片3，可以将空气增压到较高的压力，并且在抽气时可以将空气快速释放、抽出。
从上面的描述可以看出，在本发明中，通过采用简单的结构，实现了快速的充抽气操作，并且充抽气操作可以自动进行，需要很少的人工干预。
下面，参照图6A和图6B描述采用上面实施例中的充抽气装置的防护服200。
如图6A所示，防护服200由不透气材料制成，并包括外层和内层，并且在外层和内层之间形成封闭的腔体，空气可以充入到该腔体中，以使得防护服处于充气膨胀状态。在防护服200的肩部形成有气室230，充抽气装置100可以设置在该气室230内，尽管图中示出在防护服的左右肩部形成两个气室230并且每个气室230都容纳一个充抽气装置100，但是本发明并不局限于此，可以仅设置一个气室230和一个充抽气装置100，或者也可以设置多个气室和充抽气装置。
所述气室230与多个气管210连接，所述多个气管210延伸到所述防护服的腔体内，并且在气管的壁上形成多个气孔240，在充抽气装置100充气时，被加压的气体可以从气室230沿着气管210排出到防护服的腔体内，由 此该腔体充气，特别是，在抽气情况下，同样通过气管210的多个气孔240将气体从防护服中顺利抽出。
在防护服的若干位置处，设置有透气结构，例如，空气铆钉220，该空心铆钉220穿过防护服的外层和内层设置，由此在保证防护服不漏气的情况下，提供防护服的透气，以避免穿着防护服的人感受到不适。
在防护服的腔体内，可以另外充入鸭绒等保暖材料，在这种情况下，空心铆钉220的设置有利于防止该保暖材料在腔体内移位。另外，控制充抽气装置100的控制器和/或开关可以设置在例如袖口等位置，以便于人操纵。
尽管上面示出了作为上衣的防护服，但是，也可以采用裤子样式的防护服，在这种情况下，充抽气装置100可以设置在裤腿等位置。
根据本发明的防护服可以设置有感测机构，该感测机构例如可以包括加速度传感器、接近传感器、陀螺仪、图像传感器等，以便感测防护服的穿着者的速度、加速度以及距最接近障碍物的距离或感测快速接近防护服穿戴者的外来物体或人员等，并且可以在速度、加速度和距离中的至少一个或多个达到预定阈值时，该阈值可以根据穿着者与障碍物碰撞的可能性设定，并在达到该阈值时，触发充抽气装置，以给防护服快速充气，保护穿着者的人身安全。在危险情况过去之后，可以人工给防护服抽气，使得防护服可以如同普通衣物一样穿着，避免对穿着者的行动带来妨碍。
另外，在从事危险工作之前，防护服的穿着者可以主动给防护服充气或部分充气，以提前对危险做出防护。
在脱下防护服之后，由于防护服可以方便地充气和抽气，因此，防护服可以如同普通衣物一样折叠并存放，提高了存放的便利性。并且，根据本发明的防护服可以反复多次使用，降低了使用成本。
虽然已经参照示例性实施方式描述了本公开，本领域技术人员应理解的是在不背离本公开的精髓和范围的前提下可以做出各种变化和修改。因此，应该理解的是上述实施方式不是限制，而是说明性的。
