[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] In order to solve the problems in the related art caused by the inability to provide power to the automatic charging device when the mains power is cut off or abnormal, the embodiments of the present utility model propose a power-off reset device for the automatic charging device, which can continue to supply power to the automatic charging device robotic arm when the mains power is cut off or abnormal, thereby facilitating the reset of the robotic arm without manual work.

[0016] FIG1 is a structural block diagram of a power-off reset device for an automatic charging device according to an embodiment of the present invention.

[0017] As shown in Figure 1, the power-off reset device of the automatic charging equipment includes a switching unit 1, a driver 2 and a backup power module 3. The switching unit 1 is connected to the mains 4 and the backup power module 3 respectively. The first input end (power supply end) of the driver 2 is connected to the switching unit 1, the second input end (control end) of the driver 2 is connected to the backup power module 3, the output end of the driver 2 is connected to the automatic charging equipment robot 5, and the backup power module 3 is also connected to the mains 4.

[0018] Specifically, the present invention provides a backup power supply module 3, which includes an internal battery unit, and the battery unit is normally charged by the mains 4. During the process of automatic charging when the automatic charging device arm 5 is connected to the vehicle, the mains 4 supplies power to the automatic charging device arm 5 through the switching unit 1 and the driver 2. When the mains 4 is out of power or abnormal, it is immediately switched to the backup power supply module 3 through the switching unit 1, and the backup power supply module 3 is used to replace the mains 4, so that the backup power supply module 3 supplies power to the automatic charging device arm 5 through the switching unit 1 and the driver 2. The backup power supply module 3 is also connected to the driver 2, which can achieve: when the backup power supply module 3 supplies power to the robot arm, the backup power supply module 3 can control the driver 2 to drive the robot arm to forcibly detach from the vehicle end, forcibly resetting the robot arm, and ensuring that in the event of a mains power outage, the robot arm can automatically complete the detachment action without manual operation, and the vehicle can drive away smoothly.

[0019] Among them, the structures of the switching unit 1, the driver 2 and the backup power supply module 3 can be any existing ones. The switching unit 1 can be any existing switch with a switching function, such as a relay with a set of conversion contacts. The driver 2 can be the automatic charging device itself. The backup power supply module 3 can be any existing structure with power supply and control functions. Therefore, the embodiment of the present utility model does not limit the specific structure of each module.

[0020] Compared with the related art, when the mains power is cut off, the embodiment of the present invention does not require manual detachment of the robotic arm. Instead, the backup power module 3 is switched to power the robotic arm, and the driver 2 can be further controlled to drive the robotic arm to smoothly detach from the vehicle end and force a reset, thereby avoiding damage to the robotic arm, saving labor costs, reducing maintenance costs, and realizing the need for automatic charging equipment without personnel management.

[0021] Therefore, the power-off reset device of the automatic charging equipment in the embodiment of the utility model can switch to the backup power supply module to continue to power the automatic charging equipment robotic arm when the mains power is cut off during the automatic charging process, which is beneficial to avoid the phenomenon that the robotic arm cannot automatically separate from the vehicle end due to the mains power outage, and then the vehicle cannot leave normally or the robotic arm is damaged.

[0022] In one example of the present invention, as shown in Figure 2, the backup power supply module 3 includes a detection unit 31, a converter unit 32, a battery unit 33 and a first communication control board 34, wherein the detection unit 31 is respectively connected to the mains 4 and the first communication control board 34, the converter unit 32 is respectively connected to the mains 4, the switching unit 1, the first communication control board 34 and the battery unit 33, and the first communication control board 34 is also connected to the second input end of the driver 2.

[0023] The detection unit 31 can be any existing structure capable of monitoring the mains power supply and (directly or indirectly) issuing a power-off signal when the mains power supply is abnormal or outage-prone. When detecting the input voltage, a resistor divider or transformer step-down circuit can be used for detection and comparison to determine whether the mains power supply is abnormal or outage-prone. The converter unit 32 includes an AC-to-DC converter and a DC-to-AC converter (inverter), or alternatively, a bidirectional AC-to-DC converter. The specific circuit structure of each converter can be any feasible structure in the prior art. For example, the AC-to-DC converter can be a half-wave rectifier circuit, a full-wave rectifier circuit, or a bridge rectifier circuit.

[0024] Further, referring to Figure 2, the power-off reset device of the automatic charging equipment also includes a second communication control board 6 and an auxiliary power supply 7. The auxiliary power supply 7 is respectively connected to the switching unit 1 and the second communication control board 6. The second communication control board 6 is respectively connected to the first communication control board 34 and the second input end (control end) of the driver 2.

[0025] Specifically, as shown in FIG3 , during the charging process of the automatic charging device, the detection unit 31 can be used to monitor in real time whether the mains power is normal. When the detection unit 31 detects the input side voltage, it can use a resistor to divide the voltage or a transformer to reduce the voltage to detect and compare whether the mains power is normal. If it is normal, the mains power 4 can be converted from AC to DC by the converter unit 32 and then charged to the battery unit 33 until it is fully charged. When the detection unit 31 detects that the mains power is off or abnormal, the switching unit 1 immediately switches to the converter unit 32, and the detection unit 31 can send a power-off signal to the first communication control board 34. The first communication control board 34 controls the converter unit 32 to perform DC-to-AC conversion. The battery unit 33 discharges and, after the DC-to-AC conversion by the converter unit 32, provides AC power to the driver 2 through the switching unit 1, thereby powering the automatic charging device robot arm 5 through the battery unit 33. Furthermore, upon detecting a system power outage, the detection unit 31 sends a power-off signal to the first communication control board 34. The first communication control board 34 then issues a forced reset command based on the power-off signal and transmits it to the driver 2 via the second communication control board 7. Upon receiving the forced reset command, the driver 2 drives the robotic arm to detach from the vehicle, achieving a forced reset of the robotic arm. In other words, the battery unit 33 within the backup power module 3 provides energy to the robotic arm, enabling it to complete the detachment action and report a fault status. This prevents the robotic arm from being unable to detach from the vehicle due to a power outage, potentially preventing the vehicle from properly driving away or other safety hazards.

[0026] In summary, the power-off reset device of the embodiment of the present invention can detect a mains power interruption or abnormality through the detection unit and provide a forced reset command to forcibly disengage and reset the robotic arm of the automatic charging device; by providing a backup power supply, when the mains power is cut off, there is still sufficient power to unplug the automatic charging device, allowing the robotic arm to be smoothly separated from the vehicle, completing the automatic reset of the robotic arm.
