具体实施方式
下面结合附图和实施例对本发明作进一步描述。
如图所示，本实施例偏转式车辆受电装置，其包括偏摆杆1、设置在偏摆杆前部的受电器2、以及驱动偏摆杆水平偏摆的驱动机构3。所述偏摆杆1包括刚性杆102和与刚性杆连接的弹性杆101，所述受电器2连接在弹性杆的前部上。弹性杆在具体实施中可以采用橡胶棒、弹簧等。
如图1所示，本实施例中所述的驱动机构包括用于与车体连接的底座301和设置在底座上的电机302，所述偏摆杆的端部连接在电机的转轴上。
当然在不同实施例中，所述驱动机构还可为其它形式，如图2所述，所述驱动机构包括用于与车体连接的底座301、设置在底座上并与偏摆杆的后部连接的轴303、以及缸体铰接在底座上的驱动缸304，所述驱动缸的伸缩杆与偏摆杆铰接。驱动缸在具体实施中可以采用气缸、油缸、电动缸等。
本发明偏转式车辆受电装置，在组装于车顶上后，在未充电状态下，偏摆杆与车身长度方向平行，受电器朝向车尾。当车辆需要在行驶中充电时，通过驱动机构驱动偏摆杆水平偏摆，以将受电器转至与沿道路分界线或分隔线布置的供电器接触。
由于受电器是连接在弹性杆上，弹性杆的弹性变形能力使得受电器能自适应供电装置上的限位结构的位置。
并且弹性杆能缓冲车辆在行驶过程中的震动，从而保证在充电过程中受电器与供电器始终处于正确的接触位置，同时弹性杆的弹力还能使受电器与 供电装置保持一定的接触压力，使两者紧密接触。
作为对以上实施例的改进，所述受电器2包括绝缘座201、设置在绝缘座上的正极轴202、与正极轴转动配合的正极滚轮203、设置在绝缘座上的负极轴204、与负极轴转动配合的负极滚轮205、与正极轴连接的正极导线206、以及与负极轴连接的负极导线207。本改进使得受电器的正极滚轮和负极滚轮在充电过程与供电器的正极导体4和负极导体5接触时始终处于滚动状态，使得受电器与供电器接触时的摩擦阻力小，受电器不易磨损损坏，使用寿命长。
作为对以上实施例的改进，所述绝缘座上还设置有在充电时对受电器位置进行限定的限位滚轮208，充电过程中受电器上的限位滚轮处于滚动状态，使得受电器与供电器的接触摩擦阻力小，受电器不易磨损损坏。
如图3充电装置上的限位板6对受电器的上下位置进行限定，在具体实施中，限位板6的设置位置略高于受电器，受电器利用弹性杆的自适应弹性变形使其上的限位滚轮压靠在限位板6上。
又如图4所示，充电装置上的限位板6对受电器的上下位置进行限定，在具体实施中，限位板6的设置位置略低于受电器，受电器利用弹性杆的自适应弹性变形使其上的限位滚轮压靠在限位板6上。
又如图5所示，充电装置上的限位板6对受电器的在水平方向进行限定，在具体实施中，驱动机构驱动偏摆杆转动的角度略大于让限位滚轮刚好接触限位板6时的角度，受电器利用弹性杆的自适应弹性变形使其上的限位滚轮压靠在限位板6上。同时充电装置上的正极导体4和负极导体5对受电器的上下位置进行限定，在具体实施中，正极导体4和负极导体5的设置位置略高于受电器，受电器利用弹性杆的自适应弹性变形使其上的正极滚轮和负极滚轮压靠在正极导体4和负极导体5上。
又如图6所示，充电装置上的正极导体4对受电器的在水平方向进行限定，正极滚轮203同时具有了限位滚轮208的作用，在具体实施中，驱动机构驱动偏摆杆转动的角度略大于让正极导体刚好接正极滚轮203时的角度，受电器利用弹性杆的自适应弹性变形使其上的正极滚轮203压靠在正极导体 4上。同时充电装置上的负极导体5和对受电器的上下位置进行限定，在具体实施中，负极导体5的设置位置略高于受电器，受电器利用弹性杆的自适应弹性变形使其上的负极滚轮压靠在负极导体5上。
所述刚性杆102包括拉簧1021和两节相互铰接的杆段1022，且拉簧的两端分别连接在两节杆段上；在刚性杆不受外力作用时，两节杆段在拉簧作用下保持直伸状态；在充电状态，刚性杆受力会克服拉簧的拉力而产生偏转，拉簧拉的拉力可进一步增大受电器与供电装置的接触力。并且刚性杆在大接触力下还可发生偏转，可防止在车辆过于接近供电装置时避免受电器损坏。
作为对以上实施例的改进，所述弹性杆的部分杆段内设置有可在水平面内弯曲的链条103，链条可以让弹簧杆在水平方向上弯曲，但可限制弹簧杆在竖直方向上的变形。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
