Referring to fig. 1, fig. 1 is a schematic structural diagram of a charging device according to an embodiment. As shown in fig. 1, in one embodiment, there is provided a charging apparatus including a first signal receiving device 110, a first charging brush plate 120, a moving mechanism 130, and a charging device 140, wherein:
the first signal receiving device 110 is used for sensing a signal emitted by the unmanned vehicle; the first charging brush plate 120 is provided with a first charging interface 121, and the first charging interface 121 is used for being connected with a second charging interface of the unmanned vehicle; the moving mechanism 130 is fixedly connected to the first charging brush plate 120, and is configured to drive the first charging brush plate 120 to move from a first position to a second position, and to drive the first charging brush plate 120 to return from the second position to the first position, where the first charging interface 121 is connected to the second charging interface; the charging device 140 is electrically connected to the first charging brush plate 120, and is configured to charge the unmanned vehicle through the first charging interface 121.
The unmanned vehicle is a vehicle which does not need to be driven by a person. Vehicles, which are collectively called "vehicles," are machines or equipment used for transporting materials, persons, and the like. The unmanned vehicle of the present embodiment may be an unmanned forklift or the like. The first signal receiving device 110 is used for sensing a signal emitted by the unmanned vehicle, so as to determine the position of the unmanned vehicle. Specifically, when the unmanned vehicle reaches the preset charging position, the first signal receiving device 110 may receive a signal transmitted by the unmanned vehicle. The first charging interface 121 is used for being connected with a second charging interface of the unmanned vehicle, so that the charging device can charge the unmanned vehicle through the first charging interface 121. Specifically, the first charging interface 121 includes a positive electrode and a negative electrode, and similarly, the second charging interface also includes a positive electrode and a negative electrode, and then the first charging interface 121 and the second charging interface can form a path for charging after being connected. The first position may be an initial position before charging. Specifically, when the charging device does not need to charge the unmanned vehicle, the first charging brush plate 120 is located at the first position, and when the unmanned vehicle needs to be charged, the moving mechanism 130 drives the first charging brush plate 120 from the first position to the second position, so that the first charging interface 121 is connected to the second charging interface.
Specifically, when the first signal receiving device 110 senses a signal, it indicates that the unmanned vehicle has reached the preset charging position, and at this time, the moving mechanism 130 moves the first charging brush plate 120 from the first position to the second position, so that the first charging interface 121 can be connected with the second charging interface, and the charging device 140 can charge the unmanned vehicle through the first charging interface 121. After the charging is finished, the moving mechanism 130 drives the first charging brush plate 120 to return from the second position to the first position.
In this embodiment, the first signal receiving device 110 may sense a signal transmitted by the unmanned vehicle, so as to determine the position information of the unmanned vehicle, if the unmanned vehicle reaches a preset charging position, the first signal receiving device 110 may sense a signal reflected by the unmanned vehicle, and the motion mechanism 130 may drive the first charging brush plate 120 to move from the first position to the second position, so as to connect the first charging interface 121 of the charging device with the second charging interface, and the motion mechanism 130 may also drive the first charging brush plate 120 to recover from the second position to the first position after the charging of the unmanned vehicle is completed. In addition, the first charging brush plate 120 is driven to move by the moving mechanism 130, so that the convenience of charging is improved.
In this embodiment, the first charging brush plate 120 may be in a normally charged state, or may be in a charged state only when charging is required, and is not limited herein.
It is understood that the moving mechanism 130 of the present embodiment only needs to realize the function of driving the first charging brush plate 120 to move, and the specific composition of the moving mechanism 130 is not limited in the present embodiment.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a movement mechanism 130 according to an embodiment. In one embodiment, as shown in fig. 2, there is provided a motion mechanism 130 comprising a stroke push rod 131, a micro switch 132 and a stroke switch 133, wherein:
one end of the stroke push rod 131 is fixedly connected to the first charging brush plate 120, and is configured to push the first charging brush plate 120 from the first position to the second position, and to drive the first charging brush plate 120 to retract from the second position to the first position; a micro switch 132 installed on a surface of the first charging brush plate 120 for detecting a pushed position of the first charging brush plate 120; a stroke switch 133 is provided at the other end away from the first charging brush plate 120 for detecting the retracted position of the first charging brush plate 120.
Wherein, the stroke push rod 131 drives the first charging brush plate 120 to reciprocate along the linear direction. Optionally, the stroke pushing rod 131 of the present embodiment is an electric pushing rod. The electric push rod works on the principle that the rotary motion of the motor is converted into the linear reciprocating motion of the push rod.
The microswitch 132 is a switch having a minute contact interval and a snap action mechanism, which performs a switching action with a predetermined stroke and a predetermined force, covered with a case, and having a driving lever outside, and is called a sensitive switch 132 because the contact pitch of the switch is relatively small. The operating principle of the microswitch 132 is as follows: the external mechanical force acts on the action reed through a transmission element (a press pin, a button, a lever, a roller and the like), and when the action reed is displaced to a critical point, instantaneous action is generated, so that a movable contact at the tail end of the action reed is quickly connected with or disconnected from a fixed contact. When the acting force on the transmission element is removed, the action reed generates reverse action force, and when the reverse stroke of the transmission element reaches the action critical point of the reed, the reverse action is instantly finished. The micro switch 132 has small contact distance, short action stroke, small pressing power and quick on-off. The moving speed of the moving contact is independent of the moving speed of the transmission element. The microswitch 132 of the present embodiment is used to detect the advanced position of the first charging brush plate 120.
The travel switch 133 is a commonly used low current master control. The contact of the mechanical motion part is operated by the collision to realize the connection or disconnection of the control circuit, thereby achieving a certain control purpose. Generally, such switches are used to limit the position or stroke of the movement of the machine, so that the moving machine can automatically stop, move in reverse, shift or automatically move back and forth according to a certain position or stroke. The stroke switch 133 of the present embodiment is used to detect the retracted position of the first charging brush plate 120.
Specifically, if the first charging brush plate 120 is pushed to the second position, the micro switch 132 is triggered, and it can be detected whether the first charging brush plate 120 is pushed to the second position through the micro switch 132. If the first charging brush plate 120 is restored to the first position, the travel switch 133 is triggered, and it can be detected whether the first charging brush plate 120 is retracted to the first position through the travel switch 133.
The present embodiment can detect the advanced position of the first charging brush plate 120 through the micro switch 132, and can detect the retracted position of the first charging brush plate 120 through the stroke switch 133, and can accurately determine whether the first charging brush plate 120 reaches the first position or the second position.
In one embodiment, the optional charging device further comprises a controller 150, wherein:
the input end of the controller 150 is connected to the first signal receiving device 110, the micro switch 132 and the travel switch 133, the control end of the controller 150 is connected to the travel push rod 131, and the controller 150 is configured to control the travel push rod 131 to advance when the first signal receiving device 110 senses a signal, control the travel push rod 131 to stop moving when the first brush plate 120 advances to the second position, and control the travel push rod 131 to stop moving when the first brush plate 120 retracts to the first position.
The controller 150 of this embodiment may be a programmable logic controller such as a PLC or a single chip.
Specifically, when the first signal receiving device 110 senses a signal, it indicates that the unmanned vehicle reaches a preset charging position, the controller 150 controls the stroke pushing rod 131 to advance, when the first charging brush plate 120 advances to a second position, the micro switch 132 is triggered, the first charging interface 121 is connected with the second charging interface, the controller 150 controls the stroke pushing rod 131 to stop moving, and at this time, the charging device 140 can charge the unmanned vehicle through the first charging interface 121. After the charging of the unmanned vehicle is finished, the controller 150 controls the stroke push rod 131 to drive the first charging brush plate 120 to retract to the first position, and when the first charging brush plate 120 retracts to the first position, the stroke switch 133 is triggered, and then the controller 150 controls the stroke push rod 131 to stop moving.
Referring to fig. 3, fig. 3 is a schematic structural diagram of another charging device according to an embodiment. In one embodiment, as shown in fig. 3, the charging apparatus further includes a first signal transmitting device 160, wherein:
the first signal transmitting device 160 is connected to the microswitch 132 and configured to transmit an electrified indicating signal to the unmanned vehicle, where the electrified indicating signal is used to indicate that the unmanned vehicle controls the second charging brush plate to be electrified, so that the electrified second charging interface is electrically connected to the electrified first charging interface 121.
Specifically, when the micro switch 132 is triggered, an electrical signal is sent to the first signal transmitting device 160, at this time, the first signal transmitting device 160 transmits an electrified indicating signal to the unmanned vehicle, and when the unmanned vehicle receives the electrified indicating signal, the second charging interface is controlled, so that the electrified second charging interface is electrically connected with the electrified first charging interface 121, and a charging path is formed.
In the embodiment, when the first charging interface 121 and the second charging interface are connected, the first signal transmitting device 160 transmits the charging indication signal to the unmanned vehicle, so that the unmanned vehicle controls the second charging brush plate to be charged, and the second charging brush plate is not in a charged state at ordinary times, so that the second charging brush plate is prevented from being charged when not charged, and the safety of the unmanned vehicle can be improved.
It should be noted that although the first signal transmitting device 160 and the first signal receiving device 110 are disposed at the same height in fig. 3, the first signal transmitting device 160 and the first signal receiving device 110 may be disposed at different heights, as long as the first signal transmitting device 160 can transmit signals to the unmanned vehicle and the first signal receiving device 110 can receive signals transmitted by the unmanned vehicle.
In one embodiment, optionally, the first signal receiving device 110 includes a first optical-to-electrical receiving switch, and the first signal transmitting device 160 includes a first optical-to-electrical transmitting switch. In this embodiment, the photoemission switch is a device that converts an electrical signal into an optical signal for emission. The photoelectric receiving switch is a device for receiving optical signals and converting the optical signals into electric signals. Specifically, the signal transmitted by the photoelectric transmitting switch is an optical signal, and the signal received or sensed by the photoelectric receiving switch is an optical signal.
In one embodiment, optionally, the charging apparatus further comprises at least one anchor bolt 170, wherein:
an anchor bolt 170 is installed at the bottom of the charging apparatus for adjusting the height of the first charging brush plate 120.

The charging equipment can test the charging function of the unmanned vehicle before the unmanned vehicle leaves a factory.
Referring to fig. 4, fig. 4 is a schematic structural diagram of an unmanned vehicle according to an embodiment. In one embodiment, as shown in fig. 4, the unmanned vehicle includes a battery 210, a second charging brush block 220, and a second signal transmitting device 230. Wherein:
the second charging brush block 220 is provided with a second charging interface 221, the second charging interface 221 is connected with the battery 210, and the second charging interface 221 is used for charging the battery 210 in an electrified state;
the second signal transmitting device 230 is used for transmitting signals to the first signal receiving device 110.
In the charged state, the second charging interface 221 is electrically connected to the charged first charging interface 121, so that the battery 210 is charged by the charging device 140. Specifically, the second charging interface 221 includes a negative electrode matched with the positive electrode of the first charging interface 121, and a positive electrode matched with the negative electrode of the first charging interface 121. The triggering condition for the second transmitting device to transmit the signal to the first signal receiving device 110 is as follows: the unmanned vehicle reaches a preset charging position. Specifically, when the unmanned vehicle reaches the preset charging position, the second signal transmitting device 230 is opposite to the first signal receiving device 110, and the first signal receiving device 110 can sense the signal transmitted by the second signal transmitting device 230.
In one embodiment, the unmanned vehicle further comprises a second signal receiving device 240, and the second signal receiving device 240 is used for sensing the signal transmitted by the first signal transmitting device 160 of the charging apparatus.
Specifically, the first signal transmitting device 160 transmits the charging indication signal when the first charging interface 121 and the second charging interface 221 are connected, at this time, since the first signal transmitting device 160 is opposite to the second signal receiving device 240, the second signal receiving device 240 can sense the signal transmitted by the first signal transmitting device 160, and the unmanned vehicle controls the second charging brush plate 220 to be charged.
It is to be understood that, in the embodiment, the second signal receiving apparatus 240 may refer to the description of the first signal receiving apparatus 110, and the second signal transmitting apparatus 230 may refer to the description of the first signal transmitting apparatus 160, which is not described in detail in this embodiment. In one embodiment, optionally, the second signal transmitting device 230 includes a second signal transmitting switch, and the second signal receiving device 240 includes a second signal receiving switch.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a charging system according to an embodiment. In one embodiment, as shown in fig. 5, a charging system includes a charging apparatus and an unmanned vehicle. In this embodiment, the charging device may refer to the description of any one of the above embodiments, which is not described in detail in this embodiment. Similarly, the unmanned vehicle may refer to the description of any of the above embodiments, which is not repeated herein.
The following describes one of the operation processes of the charging system by taking the cooperation between the charging device and the unmanned vehicle as an example:
after the unmanned vehicle automatically runs to the preset charging position, the time is delayed for 1-3S, and the unmanned vehicle automatically turns on the second signal emitting device 230 to send out a signal (the second signal emitting device 230 of the unmanned vehicle is always kept in an on state).
After the first signal receiving device 110 of the charging apparatus receives the signal transmitted by the second signal transmitting device 230 of the unmanned vehicle, the controller 150 of the charging apparatus controls the moving mechanism 130 to extend out of the stroke push rod 131.
When the micro switch 132 is triggered, indicating that the stroke push rod 131 extends to the right position, sending a push rod pushing stopping signal to the controller 150 of the charging equipment, and simultaneously starting to send a signal by the first signal sending device 160 of the charging equipment (the first sending device signal of the charging equipment is kept all the time), after the second signal receiving device 240 of the unmanned vehicle receives the signal sent by the first signal sending device 160 of the charging equipment (the unmanned vehicle continues to receive the signal for 3S and then acts), the unmanned vehicle controls the second charging interface 221 of the battery 210 to be powered on, and then the second charging brush plate of the unmanned vehicle is powered on.
When the charging device detects the voltage of the battery 210 of the unmanned vehicle, the charging device 140 is triggered to start to operate (at this time, the first charging brush plate 120 is charged), the charging of the unmanned vehicle is started, and when a set charging time is over (for example, set for 30 minutes) or when the charging device detects that the battery 210 is fully charged, the charging device 140 stops charging (power transmission of the first charging brush plate 120 is stopped, and the positive electrode and the negative electrode on the first charging brush plate 120 are not charged), and sends a charging stop signal to the charging device.
After the controller 150 of the charging device receives the charging stop signal sent by the charging device 140, the stroke push rod 131 of the charging device still keeps in the extending state and the first signal emitting device 160 of the charging device continues to emit signals, when the unmanned vehicle detects that the electric quantity of the battery 210 is full of electricity, the unmanned vehicle firstly disconnects the signals emitted by the second signal emitting device 230, and after 5S, the charging signal is disconnected (the second charging brush plate is not electrified); when the first signal receiving device 110 of the charging apparatus does not receive the signal of the second signal transmitting device 230 of the unmanned vehicle for 5S continuously, the stroke push rod 131 starts to retract. When the travel push rod 131 retracts to trigger the travel switch 133, the travel push rod 131 retracts to the right position, and the retraction is stopped.
After the stroke push rod 131 retracts to the right position, the signal emitting device of the charging device stops emitting signals. When the second signal receiving device 240 of the unmanned vehicle does not receive the signal transmitted by the first signal transmitting device 160 of the charging equipment, the unmanned vehicle drives away from the preset charging position with a delay of 2S.
After a certain time of charging, if the unmanned vehicle needs to leave halfway after receiving the task in the charging process, the unmanned vehicle first disconnects the signal transmitted by the second signal transmitting device 230, and then disconnects the charging signal after 5S (the second charging brush plate is not charged), when the first signal receiving device 110 of the charging apparatus does not receive the signal of the second signal transmitting device 230 of the unmanned vehicle, the charging device 140 immediately stops charging (the electrode of the first charging brush plate 120 is not charged), and the stroke push rod 131 starts to retract when the first signal receiving device 110 of the charging apparatus continuously receives the signal of the second signal transmitting device 230 of the unmanned vehicle for 5S. When the travel push rod 131 retracts to trigger the travel switch 133, the travel push rod 131 retracts to the right position, and the retraction is stopped. After the stroke pushing rod 131 is retracted to the proper position, the first signal emitting device 160 of the charging apparatus stops emitting the signal. When the second signal receiving device 240 of the unmanned vehicle does not receive the signal of the first signal transmitting device 160 of the charging equipment, the unmanned vehicle drives away from the charging position with a delay of 2S.
