由上述技术方案可知，本发明提供的充电支架，伸出臂的长臂一端安装充电刷块，短臂一端安装弹性部件，因为长臂长度大于短臂长度，所以使得长臂端运动的距离大于短臂端，也就说AGV过来充电会使得长臂移动一段距离，但是短臂一端的弹性部件移动的距离就远远短于AGV移动的距离，这样使得弹性部件在很短的行程内，就能起到作用；另一方面添加了扭力弹簧，这样就大大减小了弹性部件的受力，同时使得充电刷块与充电板紧密接触，使得充电过程稳定且安全。It can be seen from the above technical solution that in the charging stand provided by the present invention, the charging brush block is installed at one end of the long arm of the extending arm, and the elastic member is installed at one end of the short arm. At the end of the short arm, that is to say, when the AGV comes to charge, the long arm will move a certain distance, but the moving distance of the elastic part at the end of the short arm is much shorter than the moving distance of the AGV, so that the elastic part is in a very short stroke. It can play a role; on the other hand, a torsion spring is added, which greatly reduces the force on the elastic parts, and at the same time makes the charging brush block closely contact with the charging plate, making the charging process stable and safe.
