[0034] The applicant has noticed that the charging pile, as an important component of the autonomous charging function of the robotic dog, plays a crucial role. With the popularization of intelligent robots such as robotic dogs, their charging requirements have also become one of the important issues. Taking the charging pile placed on the ground as an example, the positive and negative metal electrodes protrude so that the battery electrodes at the charging part can be electrically connected to the charging electrodes of the charging pile when the robotic dog lies down. The current charging pile solution is to place it on the ground and protrude the positive and negative metal electrodes. When the robotic dog needs to be charged, it only needs to lie down and let the battery electrodes on its abdomen contact the electrodes of the charging pile to start charging. However, there are some problems with the current solution. The most prominent problem is that the charging electrodes are always in a conductive state, which means that when the abdominal electrodes of the robotic dog contact the electrodes of the charging pile, instantaneous discharge and sparks may occur, which may cause damage to components and affect the service life.
[0035] Instantaneous discharge and sparks may damage the charging part of the robotic dog (e.g., abdomen, tail, etc.), which will affect the normal operation of the robotic dog. The charging electrodes being in a conductive state also means that they are still conducting electricity when not in contact with the robotic dog, which means there is a risk of short circuit. This problem may cause damage to the charging equipment and even lead to a fire.
[0036] Based on the above situation, in order to avoid the occurrence of instantaneous discharge and sparks when charging the robotic dog using the charging pile, an automatic switch control device is provided. The automatic switch control device includes a pole detection circuit and a power supply soft start switch circuit, and the pole detection circuit is connected to the power supply soft start switch circuit. The pole detection circuit is arranged near the metal electrodes of the charging pile, and the metal electrodes can be in contact connection with the pole detection circuit. For example, the pole detection circuit is arranged below the metal electrodes of the charging pile, that is, a pole detection circuit is respectively arranged below the positive and negative metal electrodes.
[0037] The pole detection circuit includes a first circuit board and at least one set of detection components, and the detection components are arranged on the first circuit board. And the pole detection circuit includes a positive pole detection circuit and a negative pole detection circuit, and the circuit structures of the positive pole detection circuit and the negative pole detection circuit are the same.
[0038] In the above automatic switch control device, by setting a pole detection circuit and a power supply soft start switch circuit in the charging pile, connecting the power supply soft start switch circuit to the pole detection circuit, and controlling the state switching of the power supply component of the charging pile based on the connection situation between multiple sets of detection components in the pole detection circuit and the metal electrodes. At the same time, the power supply soft start switch circuit gradually conducts when there is a connection between the detection component and the metal electrode in the pole detection circuit, so that the power supply component slowly supplies power to the output end of the charging pile, avoiding the long-term conduction of the internal charging electrodes (i.e., metal electrodes) of the charging pile, and realizing the slow conduction of the charging circuit to avoid the generation of instantaneous discharge sparks.
[0039] In an exemplary embodiment, the first circuit board is provided with a first signal connection terminal S1 and a second signal connection terminal S2, and each group of detection components includes a first detection unit and a second detection unit. The first detection unit of each group of detection components is connected to the first signal connection terminal S1, and the second detection unit of each group of detection components is connected to the second signal connection terminal S2.
[0040] When there is no device to be charged in contact with the charging pile, the first signal connection terminal S1 and the second signal connection terminal S2 are in a disconnected state.
[0041] When the charging pile is in contact with the device to be charged, the device to be charged presses down the metal pole piece of the charging pile. When the metal pole piece of the charging pile is pressed down, the metal pole piece will contact at least one group of the multiple groups of detection components, and then the first signal connection terminal S1 and the second signal connection terminal S2 are in a conducting state.
[0042] At this time, the power slow start switch circuit conducts slowly, so that the power supply component supplies power outward slowly through the positive and negative metal pole pieces to avoid the occurrence of sparks caused by instantaneous arcing.
[0043] In an exemplary embodiment, the first circuit board is an L-shaped board, a strip board or a circular board. In one embodiment, a group of detection components is arranged on the first circuit board. When there is a device to be charged in contact with the charging pile, the device to be charged presses down the metal pole piece of the charging pile. When the metal pole piece of the charging pile is pressed down, the first signal connection terminal S1 and the second signal connection terminal S2 are in a conducting state when the metal pole piece contacts this group of detection components. In one embodiment, the first circuit board adopts an L-shaped structure and the detection components are arranged in three groups, and the length of the first side of the first circuit board is the same as the length of the second side. One group of detection components is arranged at the end of the first side of the first circuit board, another group of detection components is arranged at the end of the second side of the first circuit board, and the remaining group of detection components is arranged at the connection of the first side and the second side. Among them, the detection components can adopt metal elastic pieces, and in some other ways, a tactile switch can also be adopted. Of course, both can be used at the same time. Further, other structures that can realize the detection of the position of the pole piece are also possible, as long as the triggering of the detection components can be realized when the device to be charged is pressed down.
[0044] Refer to Figure 1 , Figure 1 shows the circuit diagram of the pole piece detection circuit provided by an embodiment of the present application. The pole piece detection circuit provided by an embodiment of the present application includes three groups of detection components, a first signal connection terminal S1 and a second signal connection terminal S2. Among them, in this embodiment, the detection components adopt metal elastic pieces.
[0045] The first metal elastic piece J1, the second metal elastic piece J2, and the third metal elastic piece J3 are all connected to the first signal connection terminal S1, and the fourth metal elastic piece J4, the fifth metal elastic piece J5, and the sixth metal elastic piece J6 are all connected to the second signal connection terminal S2. The first metal elastic piece J1 and the fourth metal elastic piece J4 form the first group of detection components, the second metal elastic piece J2 and the fifth metal elastic piece J5 form the second group of detection components, and the third metal elastic piece J3 and the sixth metal elastic piece J6 form the third group of detection components. The three groups of detection components are arranged in a triangle on the first circuit board.
[0046] In the natural state, that is, when there is no device to be charged in contact with the charging pile, the first signal connection terminal S1 and the second signal connection terminal S2 are in a disconnected state.
[0047] When the device to be charged is in contact with the charging pile, that is, when the metal pole piece of the charging pile is pressed down, at least one of the three groups of detection components is in contact with the metal pole piece, then the first signal connection terminal S1 and the second signal connection terminal S2 are in a conducting state, and the power supply soft-start switch circuit is slowly conducted, so that the power supply component supplies power outward slowly through the positive and negative metal pole pieces. Among them, the device to be charged includes, but is not limited to, movable electrical devices such as robot dogs, floor sweepers, and electric vehicles.
[0048] In this embodiment, multiple groups of detection components are arranged on the first circuit board. When the device to be charged is in contact with the charging pile, as long as one group of detection components is in contact with the metal pole piece, the charging circuit can be in a conducting state, and the conducting state of the charging circuit changes slowly, avoiding the long-term conduction of the charging pole piece inside the charging pile, that is, the metal pole piece, and also avoiding the situation of instantaneous discharge sparks when the metal pole piece is in a conducting state and making contact.
[0049] In an exemplary embodiment, the power supply soft-start switch circuit includes a on-off control component, and the on-off control component realizes the actual function of the power supply soft-start switch circuit, that is, controls the on and off of the power supply soft-start switch circuit. In some embodiments, the power supply soft-start switch circuit further includes at least one of a surge protection component, a voltage stabilizing component, and a discharging component. In one embodiment, refer to Figure 2 , Figure 2 shows the structural schematic diagram of the power supply soft-start switch circuit in an embodiment of the present application. The power supply soft-start switch circuit includes a surge protection component, a voltage stabilizing component, an on-off control component, and a discharging component. The surge protection component is connected to the output end of the power supply component, the input end of the voltage stabilizing component is connected to the surge protection component, the on-off control component is connected to the voltage stabilizing component, the discharging component is connected to the on-off control component, the discharging component is grounded, and the on-off control component is connected to the positive metal pole piece of the charging pile.
[0050] Refer to Figure 3 , Figure 3 shows Figure 2Circuit diagram of the power supply soft-start switch circuit. The on-off control component includes an electrical connector CN1, a first resistor R1, a second resistor R2, a third resistor R3, a first capacitor C1, a second capacitor C2, and a field-effect transistor Q1. Some pins of the electrical connector CN1 are connected to the pole piece detection circuit. The first pin and the second pin of the electrical connector CN1 are respectively connected to the first signal connection end S1 and the second signal connection end S2 of a pole piece detection circuit. The third pin and the fourth pin of the electrical connector CN1 are respectively connected to the first signal connection end S1 and the second signal connection end S2 of another pole piece detection circuit. In some embodiments, the third resistor R3 and the first capacitor C1 may not be provided, and the actual function of the on-off control component can still be achieved. Of course, any solution that realizes the power supply soft-start switch circuit is within the protection scope.
[0051] Continue to refer to Figure 3 , the first pin of the electrical connector CN1 is grounded, and the fourth pin of the electrical connector CN1 is also connected to the first end of the second resistor R2. The second end of the second resistor R2 is connected to the gate of the field-effect transistor Q1. The gate of the field-effect transistor Q1 is also connected to the first end of the third resistor R3, the first end of the first resistor R1, and the second end of the second capacitor C2. The drain of the field-effect transistor Q1 is connected to the first end of the first capacitor C1, and the drain of the field-effect transistor Q1 is also connected to the positive pole piece of the charging pile, that is, the drain of the field-effect transistor Q1 serves as the output terminal OUT+ of the power supply soft-start switch circuit. The source of the field-effect transistor Q1 is connected to the first end of the first resistor R1 and the second end of the second capacitor C2, and the source of the field-effect transistor Q1 is also connected to the voltage stabilization component.
[0052] In this embodiment, the field-effect transistor Q1 is a P-channel MOS transistor. The conduction condition of the P-channel MOS transistor requires that the gate voltage is less than the source voltage. Therefore, the source is directly connected to the positive output terminal IN+ of the power supply component.
[0053] When the device to be charged contacts the charging pile, that is, the metal pole piece of the charging pile is pressed down, at least one of the three groups of detection components contacts the metal pole piece, and the first signal connection end S1 and the second signal connection end S2 are in a conducting state. The first pin and the second pin of the electrical connector CN1 are conducting, and the third pin and the fourth pin of the electrical connector are conducting, then the first end of the second resistor R2 is grounded. Therefore, a voltage difference is generated between the gate and the source of the field-effect transistor Q1, and the field-effect transistor Q1 slowly turns on, thereby promoting the conduction between the power supply component and the positive pole piece of the charging pile to supply power outward.
[0054] Continue to refer to Figure 3, the voltage stabilizing component includes a voltage stabilizing diode ZD1. The first end (i.e., the negative electrode of the voltage stabilizing diode ZD1) of the voltage stabilizing diode ZD1 is connected to the surge protection component, and the first end of the voltage stabilizing diode ZD1 is also connected to the source electrode of the field effect transistor Q1, and the second end of the voltage stabilizing diode ZD1 is connected to the gate electrode of the field effect transistor Q1.
[0055] Continue to refer to Figure 3 , the surge protection component includes a transient voltage suppression diode D1. The first end of the transient voltage suppression diode D1 is connected to the positive output terminal IN+ of the power supply component, the second end of the transient voltage suppression diode D1 is grounded and the second end of the transient voltage suppression diode D1 is connected to the negative output terminal IN- of the power supply component, and the first end of the transient voltage suppression diode D1 is also respectively connected to the source electrode of the field effect transistor Q1 and the first end of the first resistor R1.
[0056] The working principle of the transient voltage suppression diode D1 is to maintain a relatively high resistance within the operating voltage range of the device. When the voltage exceeds the set value, it will conduct quickly, leading the overvoltage to ground instantaneously to protect other components from damage. When a transient high-voltage signal appears in the circuit, the TVS diode will conduct quickly, forming a low-impedance path to short-circuit the overvoltage to ground.
[0057] Continue to refer to Figure 3 , the discharging component includes a fourth resistor R4. The first end of the fourth resistor R4 is connected to the first end of the first capacitor C1, and the second end of the fourth resistor R4 is grounded.
[0058] When the fourth resistor R4 serves as the discharging component, it discharges the residual voltage on the first capacitor C1 when there is no charging device, keeping the charging pile electrode at a low potential.
[0059] Refer to Figures 1 to 3 , when there is no device to be charged in contact with the charging pile, the first signal connection end S1 and the second signal connection end S2 are in a disconnected state, then the electrical connector CN1 is in a non-conductive state and the first end of the second resistor R2 is in a floating state. Therefore, the voltage difference between the gate and source electrodes of the field effect transistor Q1 is zero, then the field effect transistor Q1 is turned off, and the power supply component and the positive electrode of the charging pile are in an open circuit state, and the metal electrode of the charging pile is non-conductive.
[0060] When the device to be charged is in contact with the charging pile, but the device to be charged is not aligned with the metal electrode, that is, only the first signal connection end S1 and the second signal connection end S2 of one pole detection circuit are conductive, then the electrical connector CN1 is in a non-conductive state and the first end of the second resistor R2 is in a floating state. Therefore, the voltage difference between the gate and source electrodes of the field effect transistor Q1 is zero, then the field effect transistor Q1 is turned off, and the power supply component and the positive electrode of the charging pile are in an open circuit state, and the metal electrode of the charging pile is non-conductive.
[0061] When the device to be charged contacts the charging pile and both the positive and negative metal electrodes are aligned and pressed down, the first signal connection terminal S1 and the second signal connection terminal S2 of the two electrode detection circuits are both conducted, the electrical connector CN1 is in a conductive state, and the first end of the second resistor R2 is grounded. Therefore, the voltage difference between the gate and the source of the field effect transistor Q1 is negative, and the field effect transistor Q1 slowly turns on. As the field effect transistor Q1 slowly turns on, it further promotes the conduction between the power supply component and the positive electrode plate of the charging pile to supply power outward.
[0062] In one embodiment, the present application further provides a charging pile, which includes the automatic switch control device described in any of the above embodiments.
[0063] In one embodiment, the present application further provides a robot system, which includes the charging pile and the robot described in the above embodiments.

Specifically, in this embodiment, a robot dog is taken as an example.
