电动汽车是指以车载电源为动力，用电机驱动车轮行驶，符合道路交通、安全法规各项要求的车辆。由于对环境影响相对传统汽车较小，其前景被广泛看好。
充电弓是一种电动汽车的充电装置，充电弓设置在电动汽车的上方，在电动汽车需要充电时，充电汽车行驶至充电弓的下方，充电弓朝向充电汽车的顶部移动，直至充电弓的电极与电动汽车的电极接触，从而为电动汽车充电。在充电时，充电弓需要保持恒定的下降压力，以使充电弓的电极与电动汽车的电极抵接，从而保证充电效果。
现有技术中的充电弓，采用压力传感器或行程传感器来检测电极的下降压力，并依据传感器来控制充电弓的上升和下降的动力元件，达到控制下降压力恒定的目的。但是压力传感器或行程传感器在室外工作寿命不长，并且电子噪声会带来系统抖动，这将导致响应时间不快，在传感器损坏时，甚至会导致下降压力失控，还会带来安全隐患。

本申请提供了一种压力传导机构及其应用的充电弓，下面给出多个实施例对本申请提供的压力传导机构及其应用的充电弓进行详细描述。
请一并参阅图1至图4，本实施例提供的压力传导机构，包括支架1、摇杆组件2、弹性组件3、伸缩件4和施力件5。摇杆组件2包括第一摇杆21和第二摇杆22，第一摇杆21和第二摇杆22分别与所述支架1铰接。施力件5用于向第二摇杆22施加恒定的力。弹性组件3包括第一弹性件31和第二弹性件32，第一弹性件31的两端分别与第一摇杆21和支架1铰接，第二弹性件32的两端分别与第二摇杆22和支架1铰接。伸缩件4的两端分别与第一摇杆21 和第二摇杆22铰接，伸缩件4能够带动第二摇杆22移动，且在伸缩件4带动第二摇杆22下落至第五预设位置时，即第二摇杆22所能下落至的极限位置，第二摇杆22受到的合力向下且恒定。
其中，伸缩件4可以为液压缸，可以为气动缸，也可以为推杆电机等任意适合的形式，只要能够带动第一支杆221和第二支杆222移动即可。
施力件5可以为重物，向第二摇杆22施加竖直向下的力，施力件5也可以为推杆，向第二摇杆22施加水平方向的力等任意适合的形式。
支架1可以沿竖直方向设置，也可以沿水平设置等任意适合的方向设置。在支架1竖直设置时，第二摇杆22能够提供恒定的竖直向下的下降压力。在支架1水平设置时，第二摇杆22也能够提供恒定的竖直向下的下降压力。
在支架1竖直设置时，施力件5可以为重物向第二摇杆22施加竖直向下的力，第一摇杆21和第二摇杆22可以上下摆动。在支架1水平设置时，施力件5可以为推杆向第二摇杆22施加水平方向的力，第一摇杆21和第二摇杆22可以左右摆动。
本实施例中，第一弹性件31为第二摇杆22提供下降压力，第二弹性件32为第二摇杆22提供上升力，施力件5为第二摇杆22提供下降力。
使用时，将支架1竖直设置，第一摇杆21和第二摇杆22分别位于支架1的一侧，伸缩件4分别与第一摇杆21和第二摇杆22铰接，伸缩件4能够伸缩，在伸缩件4伸缩时能够带动第一摇杆21和第二摇杆22上升或下落，第二摇杆22用于带动充电弓的电极上升和下落，在第二摇杆22下落至第五预设位置，充电弓的电极与待充电装置的电极抵接，并且由于第二摇杆22下落至第五预设位 置时，第二摇杆22受到的合力向下且恒定，能够使充电弓的下降压力恒定，该压力传导机构采用机械结构保持下降压力恒定，无需使用压力传感器和行程传感器等感应设备，大大提高了压力传导机构的稳定性、可靠性和使用寿命，防止充电弓下降压力失控，提高充电弓的安全性能。
需要说明的是，本实施例中的各个部件的铰接位置、伸缩量以及各种其他的尺寸可以根据力学原理中的杠杆原理进行计算得出，此处不再赘述。
此外，本实施例中，在伸缩件4带动第二摇杆22上升至极限位置时，第二摇杆22受到的合力向上且恒定。以使第二摇杆22能够上升至适合的位置，从而使充电弓的电极与待充电装置分离。第二摇杆22包括第一支杆221和第二支杆222，第二支杆222固定在第一支杆221上，且第一支杆221与第二支杆222之间呈角度设置，第二弹性件32与第二支杆222远离第一支杆221的一端铰接，施力件5与第一支杆221远离支架1的一端连接。具体地，第二支杆222的一端与第一支杆221固定，并且第一支杆221与第二支杆222之间存在一夹角α，需要说明的是，此夹角α不包括第一支杆221与第二支杆222平行的情况。第二支杆222的长度以及与第一支杆221的角度可以通过可以根据力学原理中的杠杆原理进行计算得出，此处不再赘述。
第一弹性件31可以为弹簧或空气弹簧等任意适合的形式，第二弹性件32可以为弹簧或空气弹簧等任意适合的形式。作为一种实施方式，第一弹性件31和第二弹性件32均为弹簧。具体地，支架1竖直设置，施力件5为重物，第一摇杆21设置在第二摇杆21的上方，第二支杆222设置在第一支杆221的下方。第一弹性件31的一端与支架铰接，且铰接点位于第一摇杆21与第二摇杆22之间， 第一弹性件31的另一端与第一摇杆21铰接。第二弹性件32的一端与支架铰接，且铰接点位于第一摇杆21与第二摇杆22之间，第二弹性件32的另一端与第二支杆222远离第一支杆221的一端铰接。在伸缩件4伸长至第一预设位置时，第一弹性件31拉伸至第三预设位置，伸缩件4竖直设置，所述第一预设位置为伸缩件4伸长至最大长度所达到的位置，所述第三预设位置为所述第一弹性件31拉伸至最大长度所达到的位置。在伸缩件4缩短至第二预设位置时，第一弹性件31缩短至第四预设位置，伸缩件4竖直设置，所述第二预设位置为伸缩件4缩短至最小长度所达到的位置，所述第四预设位置为第一弹性件31缩短至最小长度所达到的位置。
更具体地，例如本实施例中，当伸缩件4伸长至第一预设位置时，整个第一支杆221产生恒定的例如10KG下降压力，当伸缩件4缩短至第二预设位置时，整个第一支杆221产生例如50KG上升力。
其中，当伸缩件4伸长至第一预设位置时，整个第一支杆221产生恒定的下降压力的原理为：第二弹性件32为第一支杆221提供上升拉力，通过第二支杆222将上升拉力传导于第一支杆221上。第一弹性件31为第一支杆221提供下降拉力，通过伸缩件4将下降拉力传导于第一支杆221上。本实施例中，当伸缩件4伸长到最大长度时，第二弹性件32传导在第一支杆221的上升力例如为120KG。施力件5例如重70KG，则整个压力传导机构传导在第一支杆221上的上升力例如为50KG。当伸缩件4伸长到最大长度时，第一弹性件31也被拉长至最大长度，使得第一弹性件31传导在第一支杆221上的下降力增大到例如60KG。第一弹性件31对第一支杆221施加的例如60KG力，加上施力件5的例如70KG的力，则下降的总重力例如为130KG，第二弹性件32对第一支杆221施加例如120KG的上升力，综合结果是，整个机构传导在第一支杆221恒定 下降压力例如为10KG。
其中，当伸缩件4缩短至第二预设位置时，整个第一支杆221产生例如50KG上升力的原理为：当伸缩件4缩短到最小长度时，第一弹性件31也缩短到最小长度，第一弹性件31此时变成支撑杆，失去下降拉力。第二弹性件32传导在第一支杆221的上升力仍为例如120KG。施力件5例如重70KG，综合结果是，整个压力传导机构传导在第一支杆221上的上升力例如为50KG。
整个压力传导机构的稳定性，耐久性原理：伸缩件4作用是释放和收回第一弹性件31的例如60KG拉力，可根据力臂的原理安放在合适的位置，能够使用小力量控制第一弹性件31的大力量，使得伸缩件4的负载小，寿命长。第一弹性件31和第二弹性件32为机械性弹性元件，会一起疲劳老化，长期使用会使得拉力减弱，但由于推挽互补的特性，当第二弹性件32的向上拉力传导于第一支杆221退化例如10KG时，第一弹性件31的下降拉力传导于第一支杆221也会同时退化例如10KG，则整个系统的上升力会损失例如10KG。但下降压力仍然恒定不变，提高了整个系统的耐久性。
请参阅图3，作为另一种实施方式，第一弹性件31和第二弹性件32均为空气弹簧。具体地，支架竖直设置，施力件5为重物，第一摇杆21设置在第一摇杆21的上方，第二支杆222设置在第一支杆221下方。第一弹性件31的一端与支架1铰接，且铰接点位于第一摇杆21上方，第一弹性件31的另一端与第一摇杆21铰接。第二弹性件32的一端与支架1铰接，且铰接点位于第二摇杆22下方，第二弹性件32的另一端与第二支杆222远离第一支杆221的一端铰接。在伸缩件4伸长至第一预设位置时，第一弹性件31缩短至第四预设位置，伸缩件4竖直设置。在伸缩件4缩短至第二预设位置时，第一弹性件31伸长至第三预设位置，伸缩件4竖直设 置。其中，在伸缩件4伸长至第一预设位置时，第一弹性件31和第二弹性件32均被压缩，此时，第一弹性件31为第二摇杆22提供下降压力，第二弹性件32为第二摇杆22提供上升力，施力件5为第二摇杆22提供下降力。其他原理与上述第一弹性件31和第二弹性件32均为弹簧的实施方式一致，此处不再赘述。
本实施例提供的压力传导机构，包括支架1、摇杆组件2、弹性组件3、伸缩件4和施力件5。摇杆组件2包括第一摇杆21和第二摇杆22，第一摇杆21和第二摇杆22分别与所述支架1铰接。施力件5设置在第二摇杆22上。弹性组件3包括第一弹性件31和第二弹性件32，第一弹性件31的两端分别与第一摇杆21和支架1铰接，第二弹性件32的两端分别与第二摇杆22和支架1铰接。伸缩件4的两端分别与第一摇杆21和第二摇杆22铰接，伸缩件4能够带动第二摇杆22移动，且在伸缩件4带动第二摇杆22下落至第五预设位置时，第二摇杆22受到的合力向下且恒定。使用时，将支架1竖直设置，第一摇杆21和第二摇杆22分别位于支架1的一侧，伸缩件4分别与第一摇杆21和第二摇杆22铰接，伸缩件4能够伸缩，在伸缩件4伸缩时能够带动第一摇杆21和第二摇杆22上升或下落，第二摇杆22用于带动充电弓的电极10上升和下落，在第二摇杆22下落至第五预设位置，即第二摇杆22所能下落的极限位置时，充电弓的电极10与待充电装置的电极抵接，并且由于第二摇杆22下落至第五预设位置时，第二摇杆22受到的合力向下且恒定，能够使充电弓的下降压力恒定，该压力传导机构采用机械结构保持下降压力恒定，无需使用压力传感器和行程传感器等感应设备，大大提高了压力传导机构的稳定性、可靠性和使用寿命，防止充电弓下降压力失控，提高充电弓的安全性能。
