导向机构6包括导向杆61和导向块62,导向杆61沿预设路径方向延伸设置,导向块62与导向杆61相连接并能够伸缩相对移动,导向块62和导向杆61中的一个与第二连接装置1相连接,导向块62和导向杆61中的另一个固定设置。导向杆61和导向块62具有导向限定作用,在本实施例中,导向杆61与第二连接装置1相连接,导向块62固定设置在电连接装置内,通过导向杆61在导向块62上伸缩移动来保证第二连接装置1沿预设路径移动,结构简单,安装设置非常方便。
导向机构6的数量为两个,两个导向机构6对称设置于驱动机构2的两侧,且两个导向块62分别连接于驱动机构2的两侧。通过两个导向机构6对称设置,使得第二连接装置1的两端受力均匀,实现第二连接装置1移动更加稳定。
检测机构3包括压力传感器31,当压力传感器31检测到压力值等于预设值时,触发控制信号并用于控制驱动机构2停止伸缩。在本实施例中,压力传感器31设置于柔性壳 体21与第二连接装置1之间并用于检测柔性壳体21与第二连接装置1之间的作用力大小来判断第二连接装置1与第一连接装置之间电连接是否到位。当压力传感器31检测到柔性壳体21与第二连接装置1之间的作用力大于预设值时,检测机构3将发出控制信号并用于控制驱动机构2停止伸缩,即不在改变空腔内的气体体积,使得柔性壳体21的整体体积不再发生改变,同时不再驱动第二连接装置1移动,实现第二连接装置1停止移动。检测机构3通过压力传感器31来检测压力大小来控制,检测精度高,便于控制,且结构简单,成本低。

驱动机构2在使用时,驱动机构2将提供驱动力并能够实现伸缩部做伸缩移动,通过伸缩部的运动将会作用力在第二连接装置1上,从而带动第二连接装置1沿靠近第一连接装置的方向移动,以使第二连接装置1与第一连接装置实现电连接。在需要断开电连接时,通过伸缩部带动第二连接装置1沿远离第一连接装置的方向移动,以使第二连 接装置1与第一连接装置之间电连接相互断开。通过伸缩部来带动第二连接装置1的移动以实现电连接或者断开,具有控制精确、稳定性高的优点,有效避免电连接过程中产生偏移错位现象,大大提高了电连接装置的安全可靠性。其中,驱动机构2可以为气缸、油缸、电推杆等能够驱动第二连接装置1移动的结构。

伸缩部自固定板11的第二侧表面贯穿并螺纹连接于固定板11,第二侧表面与第一侧表面相背。浮动板12和驱动机构2分别设置于固定板11的两侧并分别与固定板11的第一侧表面和第二侧表面相连接,使得驱动机构2在驱动以及浮动板12在移动时相互之间不会接触发生干涉现象,大大提高了电连接装置的安全稳定性。同时,沿固定板11的厚度方向上设置,有效避免占用高度方向上的空间资源,结构更加紧凑,占用空间小,实现电连接装置内在高度方向上设置第二连接装置1的数量更多。
电连接装置还包括连接支架7,伸缩部的端部通过连接支架7与第二连接装置1的第二侧表面相连接,以使伸缩部避让开接线端。伸缩部的端部将作用力在连接支架7上而不直接作用力在第二连接装置1上,使得驱动机构2与穿过第二连接装置1的接线端相互避让开,大大提高了电连接装置的安全稳定性;同时,安装设置非常方便。
连接支架7包括连接板71和两个连接柱72,连接板71的第一侧面与伸缩部相连,两个连接柱72的一端分别对称连接于连接板71的第二侧面的两端,第一侧面与第二侧面相背设置,两个连接柱72的另一端均连接于固定板11的第二侧表面且分设于多个接线端的两侧。通过两个连接柱72用于传递作用力并分别作用力在固定板11的第二侧表面且分设于多个接线端的两侧,有效避让开接线端,且两个连接柱72对称设置,固定板11两侧受力均匀,移动更加稳定。
在本实施例中,压力传感器31设置于连接板71与伸缩部之间。当压力传感器31检测到伸缩部与连接支架7之间的作用力大于或等于预设值时,此时第二连接装置1移动 至预设位置,压力传感器31将触发控制信号用于控制伸缩部停止移动,同时不再驱动第二连接装置1移动,实现第二连接装置1停止移动。通过压力传感器31来检测压力大小的方式来控制驱动机构2,检测精度高,便于控制。

具有柔性驱动结构的电连接装置在使用时,将气体充入至空腔内,使得空腔内的气体体积变大,且柔性壳体21的容积也相应变大,通过柔性壳体21的变大并会沿靠近第一连接装置的方向移动,将会驱动第二连接装置1也沿靠近第一连接装置的方向移动,以使第二连接装置1与第一连接装置实现电连接。在需要断开电连接时,将空腔内的气体排出,使得空腔内的气体体积变小,且柔性壳体21的容积也相应变小,通过柔性壳体21的变小并会沿远离第一连接装置的方向移动,将会驱动第二连接装置1也沿远离第一连接装置的方向移动,以使第二连接装置1与第一连接装置之间电连接相互断开。通过控制空腔内气体体积,使得柔性壳体21来驱动第二连接装置1的移动以实现电连接,具有控制精确、柔性好稳定性高的优点,有效避免电连接过程中产生偏移错位现象,大大提高了具有柔性驱动结构的电连接装置的安全可靠性。而且具有柔性壳体21的驱动机构2,在未充气时占用空间较小,在整体空间不变的情况下,采用该驱动机构2的电连接装置的第二连接装置1具有更长的有效移动行程。
充电仓还包括检测机构3,检测机构3用于当第二连接装置1在充电仓内移动到预设位置时触发控制信号,控制信号用于控制第二连接装置1停止移动。当第二连接装置1沿靠近第一连接装置的方向移动并实现与第一连接装置电连接时,此时第二连接装置1在充电仓内移动到达了预设位置,检测机构3将检测到第二连接装置1到达了预设位置并触发控制信号,通过该控制信号用于控制第二连接装置1停止移动,有效避免了第二连接装置1与第一连接装置之间电连接时向前移动发生过分挤压现象,防止第二连接装 置1和第一连接装置的损坏,实现对第二连接装置1移动到位的精确控制,大大提高了充电仓的安全稳定性。
在本实施例中,检测机构3设置于柔性壳体21和第二连接装置1之间。柔性壳体21将会作用力在第二连接装置1上并用于带动第二连接装置1移动,通过将检测机构3设置于柔性壳体21和第二连接装置1之间,检测机构3安装设置非常方便,且通过检测机构3检测精确,便于控制。当然,在其他实施例中,检测机构3可以设置于柔性壳体21和充电仓之间。
检测机构3包括压力传感器31,当压力传感器31检测到压力值等于预设值时,触发控制信号并用于控制驱动机构2停止改变空腔内的气体体积。在本实施例中,压力传感器31设置于柔性壳体21与第二连接装置1之间并用于检测柔性壳体21与第二连接装置1之间的作用力大小来判断第二连接装置1与第一连接装置之间电连接是否到位。当压力传感器31检测到柔性壳体21与第二连接装置1之间的作用力大于预设值时,检测机构3将发出控制信号并用于控制驱动机构2停止改变空腔内的气体体积,使得柔性壳体21的容积不再发生改变,同时不再驱动第二连接装置1移动,实现第二连接装置1停止移动。检测机构3通过压力传感器31来检测压力大小来控制,检测精度高,便于控制,且结构简单,成本低。
检测机构3包括检测件33和触发件32,检测件33和触发件32中的其中一个设置在第二连接装置1上,另一个设置在第二连接装置1在充电仓内的移动路径上,通过检测件33与触发件32匹配触发控制信号。在本实施例中,触发件32设置在第二连接装置1上,检测件33设置在第二连接装置1在充电仓内的移动路径上。当柔性壳体21驱动第二连接装置1移动并实现与第一连接装置之间电连接时,检测件33与触发件32匹配触发控制信号,检测机构3发出的控制信号并用于控制驱动机构2停止改变空腔内的气体体积,使得柔性壳体21的容积不再发生改变,同时不再驱动第二连接装置1移动,实现第二连接装置1停止移动,有效避免了第二连接装置1与第一连接装置之间电连接时向前移动发生过分挤压现象,防止第二连接装置1和第一连接装置的损坏,实现对第二连接装置1移动到位的精确控制。同时,通过检测件33和触发件32来匹配触发控制信号,检测精度高,便于控制,大大提高了充电仓的安全稳定性。

充电仓内在针对不同型号的电池包进行充电时,第二连接装置1在移动时针对不同型号的电池包需要移动的距离也存在不相同,以保证第二连接装置1与第一连接装置之间实现电连接。通过第二连接装置1在充电仓内的移动路径上间隔设置多个检测件33,触发件32设置在第二连接装置1上,第二连接装置1在移动时将会带动触发件32移动,通过触发件32与多个检测件33的触发次数来精确控制第二连接装置1的移动距离。不同型号的电池包的移动距离存在不相同时,通过多个检测件33分别与不同型号的电池包的移动距离相对应,使得不同型号的电池包通过触发件32与检测件33的触发次数来最后触发信号到匹配对应的检测件33并触发控制信号,从而来控制第二连接装置1的移动距离,实现了具有柔性驱动结构的电连接装置在针对不同型号的电池包时都能够进行充电,实现了充电仓应用范围广泛。
可以通过触发件32根据与多个检测件33的触发次数来精确控制第二连接装置1的移动距离,也可以触发件32直接与匹配的检测件33来触发控制信号。检测机构3根据接收到的检测件33触发的触发信号的数量触发相对应的控制信号,以控制第二连接装置1停止移动。不同型号的电池包的移动间距不同分别与多个检测件33相匹配对应,针对不同型号的电池包在实现电连接时,柔性壳体21来驱动第二连接装置1移动,通过触发件32只有与电池包相匹配对应的检测件33之间才能触发控制信号,从而无需计算触发件32与检测件33之间的触发信号次数,使用更加方便,且精度高。
充电仓还包括控制单元,控制单元用于获取电池包型号信息,控制单元根据检测机构3接收到的与电池包型号信息对应的触发信号,生成控制信号,控制第二连接装置1停止移动。通过控制单元获取电池包型号信息,控制单元将根据检测机构3接收到的与电池包型号信息对应的触发信号,使得触发件32与多个检测件33中相匹配对应的检测件33之间才能触发生成控制信号,从而精确控制第二连接装置1停止移动,实现对不同型号的电池包的精确充电,大大提高了具有柔性驱动结构的电连接装置的安全可靠性。
在本实施例中,检测件33设置于第二连接装置1在充电仓内的移动路径上,触发件32设置于第二连接装置1上。检测件33会产生信号,需要接出信号线,通过将多个检测件33间隔设置在第二连接装置1的移动路径上,固定设置方便,且不易损坏信号线。优选地,检测机构3包括接近开关、机械开关、光电开关或磁性开关。
充电仓还包括电池传感器,电池传感器用于检测电池承载面4上是否有电池包;控制单元与电池传感器、驱动机构2信号连接。当电池包放置在电池承载面4上,电池传感器将检测到电池承载面4上有电池包并发出信号,控制单元接收到电池传感器发出的信号并用于控制驱动机构2打开,驱动机构2将气体充入至空腔内,使得空腔内的气体 体积变大,柔性壳体21的容积也相应变大,通过柔性壳体21的变大并会沿靠近第一连接装置的方向移动,将会驱动第二连接装置1也沿靠近第一连接装置的方向移动,以使第二连接装置1与第一连接装置实现电连接,从而实现了对电池包充电。在电池包充满电之后,控制单元将控制驱动机构2将空腔内的气体排出,使得空腔内的气体体积变小,且柔性壳体21的容积也相应变小,通过柔性壳体21的变小并会沿远离第一连接装置的方向移动,将会驱动第二连接装置1也沿远离第一连接装置的方向移动,以使第二连接装置1与第一连接装置之间电连接相互断开。实现精确控制,使用更加方便。
