具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不用来限制本发明的范围。
如图1和图3所示，本发明实施例的一种多功能车载充电器，其包括壳体1、设于壳体1前端的第一电极2、设于壳体1内部PCB板（Printed circuit board，中文名称：印刷电路板）3、设于壳体1周壁的第二电极4和设于壳体1后端的电源输出端口5，该电源输出端口5可为USB接口或为电源接头等，第一电极2和第二电极4分别代表正负极，优选地，第一电极2为正极，第二电极4为负极。其中，本实施例的充电器还包括安全锤6，第一电极2可伸缩地插设于壳体的前端，安全锤6的外部套设有弹簧7，该弹簧7的一端固定在壳体1内，其另一端抵在第一电极2的内侧；安全锤6的后端固定在壳体1内，其前端的锤头6a伸出壳体1的前端，如图2所示，第一电极2缩回时可使安全锤6的锤头6a暴露在壳体1的外部。本实施例的安全锤的锤头6a的硬度优选为HRC58-62，即可以确保可将车窗玻璃击碎，又确保安全锤的锤头不易被硬物击碎。
为了提高安全锤的击打能力，本实施例的安全锤6的锤头6a为尖头锤头，可使应力集中于尖端，便于击打夹碎玻璃等需要击打的物体。此外，在安全锤6的后端还设置了硬质金属块17。本实施例的壳体1由左、右两个半壳体1a构成，如图3所示，可方便加工和拆装。其中，第一电极2和第二电极4优选为采用电极帽的结构，使其安装方便。第二电极4为对称设置的两个，其安装在左、右两个半壳体对接的位置。
本发明将安全锤集成到充电器中，减少了车用配件，进而减少车用配件的占用空间，在该充电器插入汽车点烟器的车充母座时，电极帽在弹簧的作用下回弹，可防止充电器在汽车颠簸时脱离车充母座，同时在电极帽内设置安全锤，可在紧急状况下使用，当需要使用安全锤时，只需要将充电器从车充母座上拨出，手握壳体的后部，用力将第一电极击打车窗玻璃或其他位置，第一电极在捶打时向后缩回，使得安全锤的锤头露出以击碎车窗玻璃，由于将安全锤置于容易拿到的位置，发生突发事件时，方便取出，提高了驾驶员或乘客使用的便捷性，只需将充电器从车充母座上拔出，用力击碎车窗，破窗而出，保证车内人员顺利脱险，提高了乘车的安全性。
为了方便充电器的拆装，本实施例的充电器还包括前盖8，该前盖8与壳体1的前端螺纹连接，并在前盖8的前端开设有通孔，第一电极2穿过前盖8的通孔与壳体1的前端可伸缩连接。且第一电极2的后端还设有限位台阶，该限位台阶的直径大于前盖8的通孔的孔径，第一电极2的限位台阶与前盖的通孔相配合形成防掉落结构，可防止第一电极2从前盖中脱离出来。
本实施例的安全锤6与壳体1的内侧卡接，具体地，安全锤6的后端周向设有环形卡槽，壳体1的内侧设有与该环形卡槽相匹配的环形卡环，安全锤的环形卡槽卡接在壳体的环形卡环内，由此可使安全锤牢固安装在壳体内。
参照图2和图3，本实施例的壳体1上设有缺口1b，特别是设置一个U形缺口。该缺口1b内设有刀片9，该刀片9嵌入缺口内1b，用于在紧急状况下隔断安全带等绳状物体，以便于逃生。优选地，壳体1设置缺口1b的部位为突出部1c，缺口1b设于该突出部1c内且其开口朝向第一电极2，由此使得刀片9在不使用的时候刀锋朝向车体，且缺口不裸露在壳体1上手持的部位，可防止刀片误伤到其他人或物品。
本实施例壳体的后端设有功能板10，电源输出端口5设于该功能板10上。此外，在功能板10上还设有照明设备12，照明设备12与PCB板3电连接，同时壳体1上还设有开关13，开关13与照明设备12电连接，开关13优选为按钮开关，通过开关13可以控制照明设备12的开启和关闭。开关13内设有两个控制电路，分别设为第一控制电路和第二控制电路，其中第一控制电路控制照明设备发出白光，第二控制电路控制照明设备发出闪烁的警示灯。通过长按开关，可以触发第一控制电路，控制照明设备发出白光，此时该照明设备可用作手电筒；通过短按开关，可以触发第二控制电路，控制照明设备发出闪烁的警示灯，此时可以在停车时将该充电器置于车顶或其它位置以警示其它正在行进的车辆，避免发生碰撞。本实施例的照明设备12可以采用草帽式的灯珠，也可以采用贴片式LED灯，优选为贴片式LED灯，其亮度更亮，且更加省电，可节约资源。本实施例在壳体的后端还设置了透明后盖16，并在照明设备12和透明后盖16之间依次设置了透镜14和铝圈15。
本实施例还提供了移动电源的功能，在壳体内还设有充电电池11，该充电电池设于PCB板与功能板之间，并与PCB板电连接，在充电器插入车充母座时，可以对充电电池充电，充电电池可以使充电器在不插入车充母座时也可以对电子设备进行充电和供照明设备使用，以备突发、紧急状况下使用。
本发明实施例的车载充电器，结合了充电器、安全锤、切割刀具、移动电源、手电筒的功能，多功能集于一体，使用方便，在突发事件时，可方便驾驶员或乘客使用，提高了安全防护性能，并减少了多个配件，进而减少了车用配件的占用空间。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和替换，这些改进和替换也应视为本发明的保护范围。
