Robot shutdown charging pile structure

Abstract

The invention discloses a robot shutdown charging pile structure. The structure comprises a robot, a charging pile and a charging pile elastic plate, wherein a first chassis charging pole plate and asecond chassis charging pole plate are installed at a tail end of a chassis of the robot. In the recharging process, when a magnet is detected through a Hall sensor, the robot decelerates to stop, thestroke of a magnet induced by the Hall sensor is long, a charging pile is not squeezed by the robot, moreover, mechanical triggering of a microswitch is avoided, a phenomenon of mechanical trigger failure after long-time use is avoided, so long-time reliable use can be realized, a robot electrode plate and a charging pile electrode plate are in good contact, then a wireless signal is emitted to inform the charging pile to turn on a power supply, the first chassis charging electrode plate and the second chassis charging electrode plate of the robot are in contact with a charging pile electrodeplate firstly and then are electrified, so sparks are not generated, and charging safety is improved.

Description

technical field [0001] The invention relates to the technical field of robot charging piles, in particular to a structure of a charging pile when a robot stops. Background technique [0002] The existing robot charging pile is controlled by a micro switch, but the stroke of the micro switch is short. When the micro switch of the robot chassis touches the slope of the charging pile and reaches the trigger stroke of the micro switch, the robot starts to stop, but due to Inertia, the robot is still moving backwards, resulting in a dangerous situation of squeezing the charging pile. At the same time, after long-term use, the mechanical device of the micro switch on the chassis is easily damaged. When the robot retreats again, the micro switch fails and the robot cannot stop, because the robot retreats horizontally and the charging pile electrode moves up and down. During the contact process between the two, the electrode sheet of the charging pile will cause greater resistance ...

Problems solved by technology

[0002] The existing robot charging pile is controlled by a micro switch, but the stroke of the micro switch is short. When the micro switch of the robot chassis touches the slope of the charging pile and reaches the trigger stroke of the micro switch, the robot starts to stop, but due to Inertia, the robot is still moving backwards, resulting in a dangerous situation of squeezing the charging pile

At the same time, after long-term use, the mechanical device of the micro switch on the chassis is easily damaged. When the robot retreats again, the micro switch fails and the robot cannot stop, because the robot retreats horizontally and the charging pile electrode moves up and down. During the contact process between the two, the electrode sheet of the charging pile will cause greater resistance to the robot chassis, because the robot retreats at a low speed, which will cause the robot to be unable to climb the charging pile. At the same time, the electrode sheet of the charging pile is a A cylinder with a circular arc on the upper end. When the robot is recharging, when the electrode sheet of the charging pile slides into the bottom of the robot and contacts the electrode sheet of the chassis, due to the surface contact, there will be friction during the interaction process. The resistance is large and only suitable for small ones such as sweepers. For robots with charging current, for service robots that require high current for charging, because of the high current, it will cause sparks, resulting in blackening of the pole piece after a long time, decreased conductivity, and low surface contact charging efficiency
