Fig. 1 is a schematic structural diagram of an intelligent walking device system according to one embodiment of the present disclosure.
As shown in fig. 1, the intelligent walking device system of the present disclosure may include an intelligent walking device 200 and a charging station 100, wherein the intelligent walking device 200 may be a device such as a sweeping intelligent walking device 200, a service intelligent walking device 200, and an intelligent lawn mower.
The intelligent walking device 200 can be parked at the charging station 100, so that the intelligent walking device 200 can be charged through the charging station 100.
The following describes the structures of intelligent walking device 200 and charging station 100.
In one embodiment, as shown in fig. 1, the charging station 100 may include: power supply unit 110, charge detection unit 120, and charging unit 130.
The power supply part 110 is used for supplying power; for example, dc power of a preset voltage value is supplied. In one embodiment, the power supply 110 may be an AC/DC power supply module, so that the power supply 110 can be connected to the mains and output a direct current.
The charging detection unit 120 is configured to detect whether the intelligent walking device 200 is docked with the charging station 100; in one embodiment, as shown in fig. 2, the charge detection unit 120 may be a contact switch or a micro switch, and when the intelligent walking device 200 and the charging station 100 are stably docked, the intelligent walking device 200 can trigger the contact switch or the micro switch and close the contact switch or the micro switch; that is, in the present disclosure, whether the smart walking device 200 is docked with the charging station 100 is determined by detecting the open state and the closed state of the contact switch or the micro switch.
When the smart walking device 200 is not docked with the charging station 100, the charging unit 130 is not supplied with a charging current; specifically, when charging station 100 is idle, charging unit 130 cannot provide the charging function to the outside. Also, when the smart walking device 200 is being docked with the charging station 100, the charging part 130 is not supplied with the charging current, and thus cannot provide the charging function to the outside.
When the charging detection unit 120 of the charging station 100 detects that the smart walking device 200 is docked with the charging station 100, the charging unit 130 of the charging station 100 is provided with a charging current; when charge detection unit 120 of charging station 100 detects that smart walking device 200 is not docked with charging station 100, charging unit 130 is kept not supplied with a charging current.
Thus, when charging station 100 and smart traveling apparatus 200 are docked, charging station 100 and smart traveling apparatus 200 do not generate a large current, and thus no arc is generated between the charging unit of charging station 100 and power receiving unit 220 of smart traveling apparatus 200.
Fig. 2 is a circuit schematic diagram of a smart walker system according to one embodiment of the present disclosure.
As shown in fig. 2, the power supply unit 110 includes a positive electrode and a negative electrode, wherein a capacitor may be disposed between the positive electrode and the negative electrode of the power supply unit 110, and the capacitor may be an electrolytic capacitor, so that the direct current provided by the power supply unit 110 is cleaner. In one embodiment, the cathode of the power supply unit 110 may be grounded, and the anode of the power supply unit 110 is connected to a diode to output power.
The charging part 130 includes a positive charging terminal 131 and a negative charging terminal 132, wherein the positive charging terminal 131 is connectable to a positive electrode of the power supply part 110; the negative charging terminal 132 may be grounded or may be connected to the negative electrode of the power supply unit 110. Further, when the negative electrode charging terminal 132 and the negative electrode of the power supply unit 110 are both grounded, it is also considered that the negative electrode charging terminal 132 and the negative electrode of the power supply unit 110 are connected indirectly.
In a specific embodiment, the charging station 100 may further include: and a charging control unit 140, wherein the power supply unit 110 is connected to the charging unit 130 through the charging control unit 140. In the present disclosure, the charging control part 140 may receive a switching signal and open or close a connection circuit between the power supply part 110 and the charging part 130.
For example, the charging station 100 may include a charging controller 150, and the charging controller 150 may be configured to generate a switching signal according to the signal of the charging detection part 120, and control a connection circuit between the power supply part 110 and the charging part 130 according to the switching signal.
More specifically, whether the charge detection unit 120 is triggered is detected by the charge trigger detection unit 160 of the charging station 100, wherein the charge trigger detection unit 160 obtains a high level signal when the charge detection unit 120 is triggered (e.g., when the micro switch or the contact switch is closed), and the charge trigger detection unit 160 obtains a low level signal when the charge detection unit 120 is not triggered (e.g., when the micro switch or the contact switch is open).
In this disclosure, the low level signal may be a ground signal or a voltage signal having a voltage value less than or equal to a predetermined value; the high level signal is a concept corresponding to a low level signal, the high level signal is not a voltage value corresponding to a certain voltage value, and is a voltage signal higher than a certain preset value, for example, a voltage value such as +3.3V, +5V, and the voltage value corresponding to the high level signal is less than or equal to the preset voltage value.
Accordingly, the charging trigger detecting unit 160 can be connected to the charging controller 150, so as to transmit a signal indicating whether the charging detecting part 120 is triggered to the charging controller 150, and when the signal indicating that the charging detecting part 120 is triggered is transmitted to the charging controller 150, the charging controller 150 sends a switching signal to control the charging control part 140 to be turned on, so that the electric energy of the electric energy providing part 110 can be transmitted to the charging part 130 and output to the outside through the charging part 130, thereby implementing the charging of the smart walking device 200.
On the other hand, when a signal that the charge detection part 120 is not triggered is transmitted to the charge controller 150, the charge controller 150 sends a switching signal to control the charge control part 140 to be turned off, so that the power of the power supply part 110 cannot be transmitted to the charging part 130.
In one embodiment, the charging controller 150 may be implemented by a general controller such as a CPU, a DSP, or a single chip microcomputer; the charging trigger detecting unit 160 may be a voltage dividing circuit connected in series with the charging detecting unit 120, and may determine whether the charging detecting unit 120 is triggered by detecting a voltage division of the voltage dividing circuit.
In the present disclosure, the positive charging terminal 131 is provided with a voltage signal of a preset voltage value, which may be continuously present, and the charging detection part 120 is connected to the positive charging terminal 131; more preferably, the voltage signal of the preset voltage value is formed by a pull-up resistor connected in parallel with the current switch.
The charging control unit 140 includes a current switch, and the current switch is controlled to be turned on when the charging detection unit 120 of the charging station 100 detects that the intelligent walking device 200 is docked with the charging station 100; when charge detection unit 120 of charging station 100 detects that smart walking device 200 is not docked with charging station 100, the current switch is controlled to be turned off.
In the present disclosure, the current switch is formed as a field effect transistor, as shown in fig. 2. In other embodiments, the current switch may be a transistor, a relay, or the like. Switching circuits implemented by transistors or relays are common in the art and are not described in detail herein.
In this disclosure, the charging station 100 further includes: a charging process detection part 170, the charging process detection part 170 obtaining a charging state of the charging station 100 by detecting a voltage signal of the charging part 130, whereby the charging control part 140 can be shut off when the charging station 100 is in an overvoltage state or an overcurrent state.
That is, in the present disclosure, through the arrangement of the diode D1 and the arrangement of the resistor R2, the current on the positive charging terminal 131 is very small, and the voltage on the positive charging terminal 131 is only an electric signal, which is not enough to generate an electric spark between the charging station 100 and the intelligent walking device 200.
Referring again to fig. 1 and 2, also provided in the present disclosure is an intelligent walking device 200, which may include: a rechargeable battery 210, a power receiving unit 220, a power reception detection unit 230, and a power reception control unit 240.
The rechargeable battery 210 is used for receiving electric energy to charge the rechargeable battery 210; in the present disclosure, the rechargeable battery 210 may be a lead-acid battery or a lithium battery or other devices capable of storing electric energy.
The power receiving part 220 is connected to the rechargeable battery 210 to input electric energy to the rechargeable battery 210 through the power receiving part 220; in the present disclosure, the power receiving portion 220 includes a positive power receiving terminal 221 and a negative power receiving terminal 222; in an alternative embodiment, the positive charging terminal 131, the negative charging terminal 132, the positive power receiving terminal 221, and the negative power receiving terminal 222 may be formed in the form of a charging spring. The positive electrode power receiving terminal 221 may be connected to the rechargeable battery 210 through a magnetic bead and a power receiving control unit 240; the positive power receiving terminal 221 is also connected to the negative power receiving terminal 222 through a reverse schottky diode and a current limiting resistor.
Accordingly, when the charging station 100 and the smart walking device 200 are docked, the positive charging terminal 131 and the positive receiving terminal 221 form a stable connection therebetween; negative charging terminal 132 and negative power receiving terminal 222 form a stable connection therebetween, thereby achieving a charging connection between charging station 100 and smart walking device 200.
The power reception detection unit 230 is configured to detect a change in the voltage signal of the positive power reception terminal 221, and determine whether or not the smart walking device 200 is docked with the charging station 100 based on the change in the voltage signal of the positive power reception terminal 221.
Specifically, the power reception detection unit 230 may be formed as a voltage division circuit, and determine whether the smart walking device 200 is docked with the charging station 100 by detecting the voltage division of the voltage division circuit.
For example, when a circuit connection is formed between the positive charging terminal 131 and the positive power receiving terminal 221 and the charge detection unit 120 is not triggered, the voltage at the positive power receiving terminal 221 is a VCC voltage; further, when the charge detection unit 120 is triggered, the voltage at the positive power receiving terminal 221 is lowered by the triggering of the charge detection unit 120, and thus the smart walking device 200 can also obtain a signal indicating whether the charging station 100 is docked with the smart walking device.
