如图1-图6所示，本申请提供一种空气供给单元，包括承载座1、干燥机构2、储气机构3、供气机构4以及控制阀组件；供气机构4与承载座1的一端相连接，承载座1的另一端的内部形成有气道101，控制阀组件设置于承载座1形成气道101的一端，且与气道101相连通；干燥机构2设置于承载座1内，储气机构3套设于承载座1设有供气机构4的一端，且供气机构4位于储气机构3的内部。
相对于相关技术，本申请提供的空气供给单元具有以下优势：
本申请提供的空气供给单元，通过将储气机构3、供气机构4、干燥机构2以及控制阀组件均集成在承载座1上，从而能够极大的提高空气供给单元的集成度，并使承载座1的空间得到充分的利用。
并且，由于本申请中储气机构3与承载座1的一端相连接，供气机构4设置在储气机构3内，因此，通过储气机构3能够在一定程度上对供气机构4进行保护，并能够在一定程度上阻隔供气机构4在作业时产生的震动和噪声。
而通过将控制阀组件与承载座1相连接，并通过在承载座1内对应开设的气道101，从而能够通过控制阀组件对气道101的开启和阻断，实现供气机构4的进气以及向空气弹簧供气的功能。
由于本申请中承载座1内还集成有干燥机构2，因此，通过干燥机构2还能够对供应入空气弹簧内的空气进行干燥，从而能够在一定程度上避免湿度较大的空气进入空气弹簧内，造成空气弹簧内产生冷凝水沉积影响使用的问题。
并且，由于本申请中承载座1上连接有储气机构3，因此，除相关技术中可通过将外部空气吸入对空气弹簧进行供气的方式外，也能够通过储气机构3直接向供气机构4提供稳定的清洁气源，实现为空气弹簧供气的功能，增加了供气方式，使空气弹簧的使用更加灵活稳定。
基于上述结构，如图2结合图3所示，本申请中的干燥机构2的数量可以为多个，且优选地，本申请中的干燥机构2包括第一干燥机构201和第二干燥机构202，承载座1内开设有第一容纳腔和第二容纳腔，第一干燥机构201设置于第一容纳腔内，第二干燥机构202设置于第二容纳腔内，第一容纳腔与第二容纳腔相连通。
通过使第一容纳腔与第二容纳腔相连通，能够使安装在第一容纳腔内的第一干燥机构201与安装在第二容纳腔内的第二干燥机构202相连通，从而能够增加整体空气供给单元对空气的干燥能力和干燥效率。
此处需要补充说明的是，如图3所示，本申请中第一干燥机构201和第二干燥机构202均包括干燥器主体，且本申请中的干燥器主体包括呈镂空设置的容纳壳2011以及在容纳壳2011内填充的干燥剂，采用镂空的容纳壳2011既能够减轻干燥器主体的重量，也能够提高干燥器主体的透气性。本申请中的干燥剂呈颗粒状，相应地，为保证干燥剂能够稳定存留在容纳壳2011内，因此，本申请中容纳壳2011的外部套设有尼龙网，网孔尺寸小于干燥剂的直径，从而能够在一定程度上避免干燥器四处窜动的问题。
此处需要进一步补充说明的是，在承载座1内开设两个容纳腔并设置两个干燥机构2仅为其中一种实施方式，如图2所示，本申请中的干燥机构2的数量也可为一个，且在承载座1内空间条件满足，并有对应需求的前提下，干燥机构2的数量可根据需求进行适当增加。
优选地，如图2结合图3所示，本申请中第一干燥机构201和第二干燥机构202均包括干燥器主体；承载座1内形成有容纳腔，干燥器主体和泄压阀203均设置于容纳腔内，干燥器主体与泄压阀203之间形成有连通气道2035，泄压阀203能够开启或关闭连通气道2035。
本申请通过将泄压阀203与干燥器主体相连接，一方面能够提高整体结构的空间利用率，另一方面，能够提高干燥器主体作业时的稳定性。当干燥器主体内承载的气压过大时，泄压阀203能够开启连通气道2035，从而能够将干燥器主体内的一部分空气排出，进而能够在一定程度上保证干燥器主体内部的气压稳定。
可以理解的是，由于本申请中第一容纳腔和第二容纳腔之间相互连通，因此，本申请中泄压阀203可与任一个干燥机构2集成连接，且也可以采用第一干燥机构201和第二干 燥机构202分别连接一个泄压阀203的方式实现泄压保护功能。
优选地，如图3所示，本申请提供的泄压阀203包括阀体2031、盖体2034以及阀芯2032组件；阀体2031与干燥器主体相连接，盖体2034封盖于阀体2031背离干燥器主体的一侧，且与阀体2031构成承载腔，连通气道2035与承载腔相连通；阀芯2032组件包括阀芯2032和弹性件2033，弹性件2033的一端与盖体2034相抵接，另一端与阀芯2032相连接，以使阀芯2032能够开启或封闭连通气道2035。
为保证阀体2031与干燥器主体连接的更加紧密，本申请中干燥器主体对应阀体2031的一端形成有呈阶梯状的插接部，阀体2031对应插接部的位置形成有插接槽，从而通过插接部与插接槽的对接，实现干燥器主体与阀体2031之间的紧密连接。
上述的连通气道2035形成于阀体2031上，阀体2031与盖体2034形成承载腔，连通气道2035的一端与承载腔相连通，另一端与容纳腔相连通。由于本申请中的阀芯2032组件包括阀芯2032和弹性件2033，因此，当干燥机构2内的气压过大时，气体由连通气道2035进入承载腔并推动阀体2031向远离连通气道2035的方向移动，压缩弹性件2033，从而能够开启连通气道2035。本申请中阀体2031与盖体2034之间还形成有泄压通道2036，气体由连通气道2035进入承载腔，并由泄压通道2036排出，从而能够保持干燥机构2内部气压的稳定。
而当泄压完成后，阀芯2032失去气体的推力，被压缩的弹性件2033回复至初始状态，从而推动阀芯2032向接近连通气道2035的方向移动，直至将连通气道2035封闭，从而完成一次泄压作业。
此处需要补充说明的是，本申请中承载座1内还设有第三容纳腔，第三容纳腔内设有空滤器104，且优选地，本申请中的空滤器104与第一干燥机构201和第二干燥机构202相平行设置。当干燥器机构内的气压过高通过泄压阀203进行泄压时，经过泄压通道2036排出的气体经由空滤器104排向大气。
此处需要进一步补充说明的是，为保证干燥器主体和泄压阀203与承载座1之间的密封程度，如图3所示，本申请中容纳壳2011的外壁面、阀体2031的外壁面以及盖体2034的外壁面均套设有密封圈，从而能够在一定程度上保证干燥机构2与承载座1之间的密封效果。
可选地，如图1结合图4所示，本申请中的储气机构3包括储气舱301和连接构件302，连接构件302的一端与承载座1的一端相连接，连接构件302的另一端与储气舱301的敞口端相连接。
本申请中的储气舱301用于储存空气，且通过连接构件302与承载座1相连接，从而 能够为空气弹簧提供稳定且清洁的气源。由于外部环境因素会使进入储气舱301内的空气湿度不同，当空气湿度较大时，则容易在储气舱301内产生冷凝积水，从而影响储气舱301的容量，并会影响为空气弹簧输送空气的能力。并且，当空气供给单元与空气弹簧结合后，空气供给单元沿竖直方向延伸，因此，本申请在储气舱301远离承载座1的一端开设排水口3011，即空气供给单元在实际安装状态下的底端开设排水口3011，当储气舱301内产生积水时，则可直接通过排水口3011将积水排出，从而能够在一定程度上保证空气弹簧作业的稳定。
并且，由于本申请中的供气机构4位于储气舱301内，因此，通过储气舱301既能够对供气机构4进行保护，避免灰尘等杂质进入供气机构4内，也能够在一定程度上阻隔供气机构4在作业时产生的振动和噪声。
优选地，本申请中的储气舱301由金属材料制成，从而通过储气舱301还能够在一定程度上提高供气机构4的散热效率，保证整体机构运行的稳定。
进一步优选地，如图4所示，本申请中连接构件302包括对接件3021和箍紧件3022；对接件3021的一端与储气舱301相连接，另一端与承载座1相连接，箍紧件3022套设于对接件3021的外部，用于箍紧对接件3021，使对接件3021与承载座1固定连接。
安装时，先将储气舱301与对接件3021的一端进行焊接，之后将箍紧件3022套设在对接件3021的外部，并将对接件3021的另一端与承载座1的端部相对接。最后，将箍紧件3022收拢，从而能够将对接件3021与承载座1之间箍紧，实现储气舱301与承载座1之间的稳定连接。
优选地，如图4所示，本申请中承载座1的外壁面，且沿承载座1的周向形成有环形凸部103，对接件3021的内壁面，且沿对接件3021的周向形成有环形槽3023，环形凸部103能够卡入环形槽3023内，以使对接件3021与承载座1相连接。
通过承载座1的外壁面形成的环形凸部103以及对接件3021内壁面形成的环形槽3023，能够在对接件3021与承载座1初步连接的过程中起到定位和连接作用，即当环形凸部103卡入环形槽3023后，能够对承载座1和对接件3021起到轴向上的定位，使对接件3021和承载座1之间能够稳定连接，从而能够方便操作箍紧件3022收拢。
其中，如图5所示，本申请中的供气机构4包括气泵401和活塞构件402；气泵401与承载座1相连接，活塞构件402设置于承载座1内，且气泵401的一端设置于承载座1内与活塞构件402相连接，另一端露出于承载座1设置。
本申请通过将供气机构4集成在承载座1上能够提高整体单元的集成度和空间利用率，作业时，气体进入气泵401内，并通过活塞构件402将空气压缩成高压空气进入气道101， 并由供气口102进入空气弹簧。
本申请中的活塞构件402的数量至少为一个，且如图5所示，优选地，本申请中的活塞构件402的数量为两个，且两个活塞构件402的轴线共线，从而能够在有限的空间内最大化的提高压缩空气的效率。
具体地，如图5结合图6所示，本申请中的控制阀组件包括控制阀5、控制板7构件以及压力检测件8；控制阀5的一端设置于承载座1内，且与气道101相连通，控制阀5的另一端露出承载座1设置，且与控制板7构件相连接；承载座1内形成有连通腔，气道101与连通腔相连通，压力检测件8与承载座1相连接，且压力检测件8的一端位于承载座1内，并位于连通腔内。
本申请中的控制板7构件包括PCB6和控制板7，控制阀5的机械段501设置于承载座1内，并与气道101相连通，电气段502露出于承载座1，并与PCB6相连接。而本申请中的PCB6用于控制板7和控制阀5之间的电路连接，而控制板7能够驱动控制阀5封堵或开启气道101。
优选地，本申请中的控制阀5的轴线与气泵401的轴线互相垂直，即气泵401与控制阀5呈90°设置，从而能够充分的利用承载座1的空间，使空间分布更加合理。
进一步优选地，本申请中承载座1内形成有连通腔，供气机构4的出气口和进气口均与连通腔相连通，且用于为空气弹簧输送空气的供气道也与连通腔相连通，即本申请中的连通腔为气道101的中间站，进入承载座1内的气体均需要进入连通腔内，再流向对应的气道101实现不同功能。因此，本申请在承载座1内进一步的集成了压力检测件8，通过压力检测件8能够对连通腔内的压力进行检测，从而能够根据具体压力情况做出调整，保证整体装置的作业安全性和稳定性。
优选地，本申请中的控制阀5的数量为多个，且多个控制阀5包括多个供气控制阀、多个进气控制阀以及至少一个排气阀；承载座1内对应供气控制阀的位置形成有供气道，对应进气控制阀的位置形成有进气道，对应排气阀的位置形成有排气道；供气道分别与供气机构4的出气口和连通腔相连通，并贯通承载座1形成供气口102；进气道分别与供气机构4的进气口和连通腔相连通，排气道的一端与连通腔相连通，另一端贯通承载座1与大气相连通。
本申请中的控制阀5的数量为9个，且包括一个排气阀，四个供气控制阀以及四个进气控制阀，其中四个供气控制阀用于向空气弹簧供应空气，因此，本申请中承载座1内对应形成有四条供气道，且供气道的一端与供气控制阀相连通，一端与连通腔相连通，一端与供气口102相连通。并且，本申请中的供气道还与供气机构4的出气口相连通，从而在 向空气弹簧进行供气时，先通过供气控制阀将供气道开启，之后经过供气机构4压缩后的压缩空气流经供气道通过供气口102进入空气弹簧，完成对供气弹簧供气的作业。
相应地，本申请中的进气道的一端与供气机构4的进气口相连通，另一端经过连通腔后与进气控制阀相连通，从而能够通过进气控制阀控制不同进气道的通断，进而能够选择不同的供气方式。
可以理解的是，本申请中的排气道与连通腔相连通，从而当连通腔内气压过大时，则通过控制排气阀开启排气道，实现气体的排出，保证整体气道101内的压力稳定。
此处需要补充说明的是，本申请中控制阀5的数量仅为其中一种实施方式，也可采用其他数量的控制阀实现本申请提供的功能。
此处需要进一步补充说明的是，本申请提供的空气供给单元还包括保护罩9，且保护罩9罩设在承载座1远离储气舱301的一端，并能够与承载座1形成用于容纳多个控制阀5、PCB6、控制板7以及压力检测件8的保护腔，从而能够在一定程度上提高控制阀组件的使用寿命和使用稳定性。
相应地，如图1所示，本申请中的保护罩9对应承载座1的供气道的位置形成有供气口102，从而能够实现对空气弹簧的气体供应。
以上所述仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
