空气动力装置和气动千斤顶
本申请基于申请号为201610068842.X、申请日为2016年02月02日和申请号为201610602514.3、申请日为2016年07月28日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本发明总体而言涉及空气动力的技术领域，具体而言，涉及一种使用空气动力驱动的千斤顶。
背景技术
现有随车的电动用品有很多，有电动充气泵、电动给排气泵、电动机械千斤顶、尾气千斤顶、气动千斤顶等等，这些装备功能单一，只能满足某种特定需求。
现有的气动千斤顶虽然带有自动充气功能，却没有自动排气功能，气囊充满气体伸长将车辆顶起，当工作完成之后需要将气囊收缩时，要靠汽车自身的重量将气囊下压，当汽车轮胎与地面接触后，又需要靠人员手动将气囊下压，以此来收缩气囊，操作费时费力。
另外，人们开车外出游玩时经常会携带充气床、充气垫等充气物品，给充气床、充气垫充气时要用到充气泵，充气床、充气垫在不使用时，需要把内部的气体放出，以便于折叠，减小占用空间，如果采用人工手动放气，既费时、又费力，放气效果还不好，可以采用排气泵进行放气，但这样人们外出游玩时除携带充气泵外，还得携带排气泵，增加了车内的占用空间。
目前市场上出现了充、排气泵装置，这种装置可以给充气床、充气垫等充气物品充气，但不能给汽车轮胎充气，这就导致当人们开车户外游玩时，随车需要带许多装备，且多种装备占用了很多空间。
发明内容
本发明的一个主要目的在于克服上述现有技术的至少一种缺陷，提供一种既能够自动充气也能够自动放气的空气动力装置和气动千 斤顶。
为实现上述发明目的，本发明采用如下技术方案：
根据本发明的一个方面，提供了一种空气动力装置，包括气囊和气泵，所述气泵包括两气口，所述两气口均能够通断地选择性气路连接所述气囊或气容物或大气，或者其中任一气口能够通断地选择性气路连接所述气囊或气容物或大气。
根据本发明的一实施方式，所述气泵为整体密封结构。
根据本发明的一实施方式，在所述气泵一气口连通所述气囊时，所述气泵与所述气囊之间通过换向阀通断其连接气路，使得所述气囊能够在进气、排气和保持三种状态之间切换。
根据本发明的一实施方式，所述气泵的另一气口连通所述气容物，所述气泵的一气口气路连接阀门，以通断所述气泵与所述气容物之间的气路。
根据本发明的一实施方式，所述空气动力装置还包括有控制结构，所述控制结构控制所述换向阀和所述阀门动作。
根据本发明的一实施方式，所述气容物为充气物。
根据本发明的一实施方式，所述气容物为充气源。
为实现上述发明目的，本发明还采用如下技术方案：
根据本发明的另一个方面，提供了一种气动千斤顶，包括如上所述的空气动力装置。
根据本发明的一实施方式，所述气动千斤顶还包括支撑结构，所述支撑结构连接设置于所述气囊的一端。
根据本发明的一实施方式，所述气泵密封夹设于所述支撑结构和所述气囊之间。
由上述技术方案可知，本发明的的优点和积极效果在于：
本发明中气泵的两个气口，可选择性地连通气囊和气容物，在需要给气囊和气容物充气时，采用充气源即可，在需要给气囊放气时，一样通过气泵自动排出，在需要给气容物例如游泳圈等排气时，利用气泵自动排出，实现快速排气功能，因此本发明可同时具有多种功能，满足人们日益多样化的需求，具有十分广阔的市场前景。

第一实施例
根据一示例性实施例示出的本发明的空气动力装置的结构如图1所示。该实施例中，空气动力装置包括气囊61和气泵62。其中，气囊61具有较大弹性，内部具有充气空间，在充气时膨胀、放气后收缩，形成可变体积。
该实施例中，气泵62包括一活塞623，活塞623在气腔624中移动，形成变化体积，从而实现抽压气体的功能。该实施例中，气泵62包括第一气口621和第二气口622，第一气口621可以是进气口也可以出气口，同样的，第二气口622也可以是进气口和出气口，第一气口621和第二气口622相反，一个是进气口，则另一个是出气口。
该实施例中，第一气口621能够通断地气路连接气囊61，其中该通断功能由换向阀64实现，使得气囊61能够在进气、排气和保持 三种状态之间切换。第二气口622能够通断地气路连接气容物63。该气容物63可以是充气源、充气物和大气中的任一种，在使用充气源时，可以对气囊61进行充气，在使用充气物时，可以对充气物和气囊61之间进行气体互换，从而实现两者的充放气，在直接连通大气时，可以对气囊61进行自主的动力放气。该实施例中，气泵62的第二气口622的气路上连接一阀门65，以通断气泵62与气容物63之间的气路。该实施例中，空气动力装置还可选择地包括有控制结构(图中未示出)，控制结构控制换向阀64和阀门65动作。
该实施例中，气泵62还采用了密封结构66，该密封结构66为整体密封结构，以使气泵62的另一气口仅能够连通气容物63。该密封结构66可以保证气流的方向性，也客观上确保压力对充放气的作用，从而不但可以实现单向充气，还可实现双向充气，或者对其中的气囊61或气容物63的充气和放气。
第二实施例
根据一示例性实施例示出的本发明的气动千斤顶的结构如图2和图3所示。该实施例中，气动千斤顶包括如第一实施例所述的空气动力装置。另外，该气动千斤顶还包括支撑结构，支撑结构连接设置于气囊的一端，气泵密封夹设于支撑结构和气囊之间。
以下为详细介绍一可选择地具体实施例，该实施例中，气动千斤顶包括气囊1、托盘2、电动气泵3、支撑盖板4、换向阀组5和顶盖6，气囊侧面和底面组成一个半封闭的橡胶整体，气囊可轴向伸缩，在气囊上端设有开口，开口设有两个密封层，内侧密封层11和外侧密封层12，气囊内设有托盘2，托盘底部设有气口21，托盘上部边缘和橡胶气囊内侧密封层21实现密封，托盘内放置有电动气泵3， 在气囊上端开口处设有支撑盖板4，支撑盖板4下边缘和气囊外部的密封层22形成密封，由支撑盖板、托盘和气囊上端开口的内侧壁之间形成密闭空间，且托盘与支撑盖板用螺丝连接，实现固定。在支撑盖板上设有气泵出气口通孔42、与托盘气口相对应的通孔41以及补给气口43，在支撑盖板上还设有压力表安装位45和电源接线端子44，接线端子下端与电动气泵电机线圈相连。在支撑盖板上方设有换向阀组5，气泵出口通过支撑盖板的出气口通孔42后连接有压力表并且与换向阀组5相连。装置的顶部设有顶盖6，顶盖内部中空，顶盖底部与支撑盖板接触，换向阀组设置于顶盖内部，顶盖侧面设有气管出口、电源线口和通气孔，顶板可与汽车底部接触，直接顶起车辆。
该实施例中，参照图4-图7所示。气动千斤顶还设有气管、电源线、电源开关和照明灯具等，也可设有放气阀、自动溢气阀或者电子控制系统等。气囊为能够轴向折叠的结构，并采用环状分段结构，每段气囊在充气后呈圆形鼓起状，气囊的段数为2～5段，图2所示的气囊的段数为3。该实施例中，在支撑盖板4上设有以下孔口：气泵出气口通孔42、通孔41以及补给气口43，其中通孔41在安装时与托盘底部的气口21相对应。
如图4所示，在本发明的车载空气动力装置中，形成有两个密闭空间，一个是由托盘下壁面和气囊内壁之间形成的密闭空间Ⅰ，另一个是由支撑盖板下壁面、托盘上壁面和气囊上端开口的内侧壁之间形成的密闭空间Ⅱ。换向阀组的D1阀口接气管V1，D2阀口接气管V2，D3阀口接气管V3，D4阀口接气管V4，其中气管V1穿过支撑盖板的补给气口43进入密闭空间Ⅱ，气管V2穿过支撑盖板的气泵出气口通孔42连接电动气泵，气管V3穿过支撑盖板的通孔41，再穿过托盘气口21后进入密闭空间Ⅰ，气管V4从顶盖侧面伸出，在气管 V4端口处接有气嘴。
该实施例的工作原理如下所述：
千斤顶使用时，外界空气进入换气阀组，气体经气管V1进入密闭空间Ⅱ给电动气泵补气，气泵工作，气体经气管V2、换向阀组、气管V3进入密闭空间Ⅰ，密闭空间Ⅰ充气后膨胀，气囊伸长，气囊顶部的顶盖将车辆顶起。
需要气囊收缩时，使气囊空气经气管V3通入换向阀组，气体经气管V1进入密闭空间Ⅱ给电动气泵补气，气泵工作，气体经气管V2、换向阀组后排入大气，气囊收缩。
当需要给轮胎、救生圈、充气垫、充气床等充气时，外界空气进入换气阀组，气体经气管V1进入密闭空间Ⅱ给电动气泵补气，气泵工作，气体经气管V2、换向阀组、气管V4后，通过气嘴给轮胎等充气物品充气。
当需要给救生圈、充气垫、充气床等充气物品排气时，由气嘴接入充气物品，气体经气管V4进入换气阀组，气体经气管V1进入密闭空间Ⅱ给电动气泵补气，气泵工作，气体经气管V2、换向阀组后排入大气，完成排气操作。
工业实用性
本发明中气泵的两个气口，可选择性地连通气囊和气容物，在需要给气囊和气容物充气时，采用充气源即可，在需要给气囊放气时，一样通过气泵自动排出，在需要给气容物例如游泳圈等排气时，利用气泵自动排出，实现快速排气功能，因此本发明可同时具有多种功能，满足人们日益多样化的需求，具有十分广阔的市场前景
