Detailed Description
Hereinafter, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement them. Also, for the sake of clarity, parts not relevant to the description of the exemplary embodiments are omitted in the drawings.
Fig. 1 shows a schematic view of a charging system according to an embodiment of the present disclosure.
As shown in fig. 1, the charging system includes a charging apparatus 100 and an electronic apparatus 200.
The charging apparatus 100 may include an external power supply device capable of charging the electronic apparatus. The charging apparatus 100 may be a portable charger or a charging post installed at a fixed place. The power supply of the charging device 100 may be, for example, a nickel-cadmium battery, a lithium ion battery, a nickel-hydrogen battery, or the like, or may be a direct current or alternating current power supply transmitted through a power transmission line.
The electronic device 200 may include a device capable of operating using power of a charging device, and the electronic device 200 may be, for example, a household robot such as a window cleaning robot, a floor cleaning robot, or the like, or may be an electric vehicle such as a hybrid vehicle, an electric vehicle, or the like, or may be other electric devices.
Fig. 2 shows a block diagram of a charging device according to an embodiment of the present disclosure.
As shown in fig. 2, the charging apparatus 100 includes: a charging circuit 110, a charging electrode 120, and a limit switch 130. The charging electrode 120 is connected to the charging circuit 110, and the limit switch 130 is connected to the charging circuit 110.
The charging electrode 120 is movable relative to the limit switch 130, and the limit switch 130 activates the charging circuit 110 when the charging electrode 120 is moved to a first position relative to the limit switch 130.
According to the embodiment of the present disclosure, the limit switch 130 is configured to convert the mechanical displacement into an electrical signal, so as to disconnect or connect the charging circuit 110 to a charging power source (located inside the charging device 100 and not shown in the figure), thereby playing a role in controlling the charging device 100 to supply power to the electronic device 200.
Fig. 3 shows a block diagram of an electronic device according to an embodiment of the present disclosure.
As shown in fig. 3, the electronic apparatus 200 includes: device electrodes 210, device charging circuitry 220, and a battery 230. Device charging circuitry 220 is connected to device electrode 210 and battery 230 is connected to device charging circuitry 220. When the electronic device 200 is charged, the device electrode 210 comes into contact with the charging electrode 120 of the charging device 100, receives power from the charging electrode 120, and charges the battery 230 through the device charging circuit 220.
Fig. 4 shows a schematic diagram of an operating principle of a charging device according to an embodiment of the present disclosure.
As shown in fig. 4, the work flow of the charging apparatus 100 is as follows: when not charging, as shown in fig. 4 a, the charging electrode 120 does not contact the limit switch 130, and there is a certain safety distance between the two. When the electronic device 200 needs to be charged, the device electrode 210 moves to contact with the charging electrode 120, and then the charging electrode 120 is continuously pushed to move forward, and after the device electrode 210 moves to contact with the charging electrode 120, for example, when the device electrode 210 pushes the charging electrode 120 to move to the first position relative to the limit switch 130, the limit switch 130 starts the charging circuit 110 to charge the electronic device 200.
According to the embodiment of the present disclosure, the limit switch 130 is disposed in the middle of the moving range of the end T of the charging electrode 120 near the limit switch 130. The range of movement of the tip T may be, for example, the entire stroke of the tip T from starting to moving as the device electrode 210 pushes the charging electrode 120 to stopping moving as the device electrode 210 is inserted into position. Thus, when the device electrode 210 just contacts the charging electrode 120, the limit switch 130 is not activated just before the stroke starts, and when the stroke advances to the middle, the charging electrode 120 is sufficiently contacted with the device electrode 210, and the limit switch 130 is activated and activates the charging circuit 110. Thus, it is possible to avoid potential safety hazards due to arc discharge at the contact portion caused by the voltage output from the charging electrode 120 starting when the device electrode 210 is not sufficiently contacted with the charging electrode 120. According to the embodiment of the present disclosure, in consideration of the difference of safety parameters such as voltage and current in an actual scene, the position of the limit switch 130 may be set accordingly, so as to ensure that the limit switch 130 starts the charging circuit 110 after the charging electrode 120 is in sufficient contact with the device electrode 210, so that the charging electrode 120 is in a power suppliable state.
According to the embodiment of the present disclosure, the limit switch 130 turns off the charging circuit 110 when the charging electrode 120 moves to the second position relative to the limit switch 130. According to the embodiment of the present disclosure, the limit switch 130 is disposed in the middle of the moving range of the end T of the charging electrode 120 on the side close to the limit switch 130, and the moving range of the end T may be, for example, the entire stroke of the end T from the start of moving due to the device electrode 210 pushing the charging electrode 120 to the stop of moving due to the device electrode 210 being inserted into position. Thus, when the reverse stroke of the charging electrode 120 begins, the limit switch 130 is not triggered to turn off the charging circuit 110, so that the situation that the limit switch 130 is triggered to turn off the charging circuit 110 due to small-amplitude displacement of the charging electrode 120 caused by slight looseness of the device electrode 210 can be avoided, and the stability of the charging process is ensured. When the charging electrode 120 moves to the middle of the reverse stroke along with the pulling-out of the device electrode 210, the limit switch 130 is triggered to turn off the charging circuit 110, and at this time, the charging electrode 120 and the device electrode 210 still keep sufficient contact. When charging electrode 120 is separated from device electrode 210, charging circuit 110 has been turned off. This effectively avoids the potential for arcing when the charging electrode 120 is separated from the device electrode 210 due to the voltage still present on the electrodes.
It is understood that although fig. 4 illustrates a contact limit switch as an example, the disclosure may also use a non-contact limit switch, such as an electro-optical limit switch, an inductive limit switch, etc.
Fig. 5 shows a block diagram of a charging device according to another embodiment of the present disclosure. As shown in fig. 5, the charging apparatus 100 includes: charging circuit 110, charging electrode 120, limit switch 130, and wireless communication circuit 140. The charging electrode 120 is connected to the charging circuit 110, and the limit switch 130 is connected to the charging circuit 110. The charging circuit 110 includes a control circuit 111, and the wireless communication circuit 140 is connected to the control circuit 111.
The limit switch 130 is connected to the control circuit 111, and when the charging electrode 120 moves to a first position relative to the limit switch 130, the limit switch 130 triggers the control circuit 111 to activate the charging circuit 110. When the charging electrode 120 moves to a second position relative to the limit switch 130, the limit switch 130 triggers the control circuit 111 to turn off the charging circuit 110.
When the charging electrode 120 moves to a first position relative to the limit switch 130, the limit switch 130 triggers the control circuit 111 to control the wireless communication circuit 140 to transmit a charging signal. When the charging electrode 120 moves to a second position relative to the limit switch 130, the limit switch 130 triggers the control circuit 111 to control the wireless communication circuit 140 to transmit the power-off signal.
According to the embodiment of the present disclosure, when the charging electrode 120 moves to the first position with respect to the limit switch 130, the wireless communication circuit 140 transmits a charging signal to the electronic device 200 being charged, and the electronic device 200 enters a charging state in response to the charging signal. At this time, the charging electrode 120 is sufficiently in contact with the device electrode 210 and the charging circuit 110 is started, the charging process can be safely and smoothly performed without the arc problem. Moreover, when the charging electrode 120 is just in contact with the device electrode 210, the electronic device 200 is not in a charging state, and the electronic device 200 may be prevented from being damaged by residual charges possibly existing on the charging electrode 120 and/or the device electrode 210.
According to the embodiment of the present disclosure, when the charging electrode 120 moves to the second position relative to the limit switch 130, the wireless communication circuit 140 transmits a power-off signal to the charged electronic device 200, and the electronic device 200 enters the power-off state in response to the power-off signal. At this time, the charging electrode 120 is in sufficient contact with the device electrode 210 and the charging circuit 110 is turned off, so that the charging process can be safely and smoothly ended without the arc problem. When the charging electrode 120 is separated from the device electrode 210, the electronic device 200 is not in the charging state, and the electronic device 200 may be prevented from being damaged by residual charges possibly existing on the charging electrode 120 and/or the device electrode 210.
According to the embodiment of the present disclosure, the control circuit 111 controls the wireless communication circuit 140 to transmit the hold signal during the charging process, and when the charging electrode 120 moves to the second position relative to the limit switch 130, the limit switch 130 triggers the control circuit 111 to control the wireless communication circuit 140 to stop transmitting the hold signal. The hold signal may be used to indicate that the charging process is in progress and that the charging electrode 120 is in sufficient contact with the device electrode 210. When the charging process ends, the transmission of the hold signal is stopped, and the electronic device 200 may stop charging accordingly. At this time, the charging electrode 120 is in sufficient contact with the device electrode 210 and the charging circuit 110 is turned off, so that the charging process can be safely and smoothly ended without the arc problem. When the charging electrode 120 is separated from the device electrode 210, the electronic device 200 is not in the charging state, and the electronic device 200 may be prevented from being damaged by residual charges possibly existing on the charging electrode 120 and/or the device electrode 210.
Fig. 6 shows a block diagram of an electronic device according to another embodiment of the present disclosure. As shown in fig. 6, the electronic apparatus 200 includes: device electrodes 210, device charging circuitry 220, battery 230, and device wireless communication circuitry 240. Device charging circuitry 220 is coupled to device electrode 210, battery 230 is coupled to device charging circuitry 220, and device wireless communication circuitry 240 is coupled to device charging circuitry 220.
When the device electrode 210 moves the charging electrode 120 of the charging device 100 to a first position relative to the limit switch 130 of the charging device 100, the device wireless communication circuitry 240 receives the charging signal and accordingly triggers the device charging circuitry 220 to begin charging the battery 230.
According to an embodiment of the present disclosure, during charging, the device wireless communication circuit 240 may receive a hold signal from the charging device 100, which may be, for example, a wireless heartbeat signal or the like. During the charging process, the wireless communication circuit 140 sends a holding signal to indicate that the charging apparatus 100 is in a normal power supply state, and the device wireless communication circuit 240 can perform a normal charging process when receiving the holding signal.
In accordance with an embodiment of the present disclosure, when the device electrode 210 moves the charging electrode 120 of the charging device 100 to a second position relative to the limit switch 130 of the charging device 100, the device wireless circuitry 240 receives the power down signal or no longer receives the hold signal and accordingly triggers the device charging circuitry 220 to stop charging the battery 230.
Considering that the remaining power may exist on the device electrode 210 when the electronic device 200 needs to be charged, if the device electrode 210 is in a connected state with the device charging circuit 220, an arc or other safety hazards are likely to be generated when the device electrode 210 is in contact with the charging electrode 120. Thus, when device electrode 210 is not in sufficient contact with charging electrode 120, device charging circuit 220 may not be in a charging state, e.g., device electrode 210 and device charging circuit 220 may not be in a connected state, but rather resume charging the battery when device wireless communication circuit 240 receives a charging signal transmitted by wireless communication circuit 140 of charging device 100. When the device wireless communication circuitry 240 receives the power-down signal or no longer receives the hold signal, the electronic device 200 may stop charging accordingly. At this time, the charging electrode 120 is in sufficient contact with the device electrode 210 and the charging circuit 110 is turned off, so that the charging process can be safely and smoothly ended without the arc problem. When the charging electrode 120 is separated from the device electrode 210, the electronic device 200 is not in the charging state, and the electronic device 200 may be prevented from being damaged by residual charges possibly existing on the charging electrode 120 and/or the device electrode 210.
Fig. 7 shows a schematic structural diagram of a reset mechanism according to an embodiment of the present disclosure.
According to an embodiment of the present disclosure, the charging device 100 further comprises an electrode chamber 150 and a reset mechanism 160. The charging electrode 120 is at least partially disposed in the electrode chamber 150, and the reset mechanism 160 drives the charging electrode 120 to move to maintain contact with the device electrode 210 of the charged electronic device during movement of the charging electrode 120 to follow the device electrode 210 of the charged electronic device toward the exterior of the electrode chamber 150. For example, the return mechanism 160 may be a spring or other resilient mechanism.
