DETAILED DESCRIPTION

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0053] At present, in order to reduce the power consumption of the cleaning device, when the cleaning device is not in use, the cleaning device is controlled to enter a low power consumption mode. When the cleaning device is in use, the cleaning device is controlled to switch from the low power consumption mode to the working mode. For example, the battery management circuit in the cleaning device is controlled to charge or discharge the battery, so as to adjust the operating mode of the cleaning device. However, in the process of controlling the cleaning device to switch from the low power consumption mode to the working mode, there is a problem of high power consumption.

[0054] In the related art, a charge and discharge activation circuit is disclosed, including a charge activation circuit, a discharge activation circuit, a gating circuit and a battery management system (BMS). The charge activation circuit and the discharge activation circuit are coupled to the gating circuit, and the gating circuit is coupled to the battery management system to realize the battery management system's charge and discharge management of the battery. For example, the gating circuit is triggered by the charge activation circuit and the discharge activation circuit to generate continuous high and low level signals, and the battery management system implements charge and discharge management based on the continuous high and low level signals, and adjusts the operation mode of the cleaning equipment. Since the high level signal is continuous, it will cause a large loss when the charge and discharge activation circuit activates the battery management system. In addition, the structure of the gating circuit is also relatively complex, and it is easy to generate interference signals. In addition, there will be delays when the high and low level signals pass through the gating circuit, resulting in a slow response speed of the battery management system.

[0055] Based on this, the present disclosure provides a battery activation circuit, which activates the battery management circuit through an activation pulse signal. Since the activation pulse signal is an electrical signal with a high level and a short duration, it will be converted to a low level once the activation pulse signal is transmitted. Compared with a continuous high level signal, it can effectively reduce the power consumption generated by activating the battery management circuit. At the same time, since the activation pulse signal has a fast response speed and does not need to pass through a gating circuit, the waiting time during the battery activation process is reduced, and the user experience is improved.

[0056] An exemplary embodiment of the present disclosure provides a battery activation circuit, such as Figure 1 As shown, the battery activation circuit includes a pulse generating circuit 10 and a battery management circuit 20. The pulse generating circuit 10 is used to generate an activation pulse signal. The battery management circuit 20 is coupled to the pulse generating circuit 10, and the battery management circuit 20 is used to couple to a battery 30. The activation pulse signal is used to activate the battery management circuit 20.

[0057] In this embodiment, the battery activation circuit includes a pulse generating circuit and a battery management circuit. The battery management circuit is coupled to the pulse generating circuit, and the battery management circuit is used to couple to the battery. The battery management circuit can be activated under the activation pulse signal output by the pulse generating circuit to control the battery to charge and discharge, so that the cleaning device is converted from a low power consumption mode to an operating mode. Since the activation pulse signal is an electrical signal with a high level and a short duration, it will be converted to a low level once the activation pulse signal is transmitted, so it can effectively reduce the power consumption generated by activating the battery management circuit. At the same time, due to the fast response speed of the activation pulse signal, the waiting time during the battery activation process is reduced, and the user experience is improved.

[0058] Exemplarily, the battery 30 is formed by connecting a plurality of cells in series, and the battery 30 formed by connecting the cells in series has a positive electrode and a negative electrode. The battery management circuit 20 is connected to the plurality of cells and can detect the state of each cell to protect the battery 30.

[0059] In one embodiment, if Figure 2 As shown, the pulse generating circuit 10 includes a first pulse generating circuit 11 and an activation circuit 12. The first end of the first pulse generating circuit 11 is used to couple with the first end of the first switch 40, and the first pulse generating circuit 11 is used to generate a first pulse signal when the first switch 40 is closed. The first end of the activation circuit 12 is coupled with the second end of the first pulse generating circuit 11, and the second end of the activation circuit 12 is coupled with the first end of the battery management circuit 20, and the activation circuit 12 is used to convert the first pulse signal into an activation pulse signal. The second end of the first switch 40 is used to couple with the positive electrode of the battery 30.

[0060] In this embodiment, the first switch generates a first pulse signal when it is closed, and the first pulse signal is converted into an activation pulse signal through the activation circuit, and the activation pulse signal activates the battery management circuit. By generating the first pulse signal when the first switch is closed, and converting the first pulse signal into an activation pulse signal, it is possible to avoid continuously generating the activation pulse signal after the first switch is closed. In this way, when the cleaning device is in storage or transportation, the first switch is accidentally closed due to external reasons, and the battery management circuit will be activated to convert the cleaning device from a low power mode to an operating mode. When the cleaning device is not running, the battery management circuit will convert the cleaning device to a low power mode again after a delay time to reduce the power consumption of the cleaning device. Among them, the delay time can be achieved by a timing module in the cleaning device. For example, the delay time is set to 15s, so when the first switch is closed for 15s, if the cleaning device is not running, it will enter a low power mode.

[0061] Exemplarily, the first switch 40 may be a key switch, a touch switch, a voice wake-up switch, or the like.

[0062] In one embodiment, if Figure 3 As shown, the first pulse generating circuit 11 includes a first resistor 111 and a first capacitor 112. The first end of the first resistor 111 is used to couple with the first switch 40, and the second end of the first resistor 111 is coupled with the first end of the activation circuit 12. The first capacitor 112 is coupled with the first resistor 111 in parallel.

[0063] In this embodiment, since the first capacitor has a high response capability to the rate of change of the voltage, at the moment of charging the first capacitor, the voltage of the first capacitor will be instantaneously higher than the input voltage. Therefore, when the first switch is closed, the voltage of the first capacitor begins to rise. Since the first capacitor is coupled in parallel with the first resistor, the voltage of the first capacitor will instantaneously rise and be higher than the voltage of the positive electrode of the battery to generate a first pulse signal. The first pulse signal is converted into an activation pulse signal by the activation circuit, and the battery management circuit is activated after receiving the activation pulse signal. As the voltage of the first capacitor reaches a peak value, the voltage of the first capacitor gradually decreases to the voltage of the positive electrode of the battery. Since there is no activation pulse signal in the battery activation circuit at this time, the battery management circuit will not be activated. The whole process shows that the first pulse signal is a signal that rises first and then falls, so the activation pulse signal transmitted to the battery management circuit will be converted from a high level to a low level. This can effectively reduce the power consumption generated by the battery activation circuit activating the battery management circuit.

[0064] For example, if the battery management circuit 20 is to be activated again after the first switch 40 is closed, the battery management circuit 20 can only be activated again by closing the first switch 40 again to generate a new first pulse signal.

[0065] In one embodiment, if Figure 3 As shown, the first pulse generating circuit 11 further includes a first buck circuit 113. A first end of the first buck circuit 113 is used to couple with a first end of the first switch 40, a second end of the first buck circuit 113 is coupled with a first end of the first resistor 111, and the first buck circuit 113 is used to reduce the voltage of the positive electrode of the battery 30.

[0066] In this embodiment, the first step-down circuit can reduce the voltage of the positive electrode of the battery to a safe voltage range that the battery management circuit can withstand. On the one hand, it can protect the battery management circuit from damage, and on the other hand, it can also reduce the loss in the battery activation circuit.

[0067] In one embodiment, if Figure 3 As shown, the first voltage-reducing circuit 113 includes a first voltage-stabilizing tube 114 . The cathode of the first voltage-stabilizing tube 114 is used to couple with the first switch 40 , and the anode of the first voltage-stabilizing tube 114 is coupled with the first end of the first resistor 111 .

[0068] In this embodiment, the first voltage regulator is connected in series between the first switch and the first resistor, so as to reduce the output voltage of the battery to a safe voltage range that the battery management circuit can withstand, thereby playing a voltage reduction function. Moreover, since the voltage at both ends of the first voltage regulator is stable when the first voltage regulator is reversely broken down, the first pulse circuit can be kept stable, thereby improving the reliability of the battery activation circuit.

[0069] Exemplarily, the first step-down circuit 113 may include, in addition to the first voltage regulator tube 114 , a plurality of first diodes coupled in series.

[0070] In one embodiment, if Figure 3 As shown, the first pulse generating circuit 11 further includes a second resistor 115 , a first end of the second resistor 115 is coupled to the anode of the first voltage regulator tube 114 , and a second end of the second resistor 115 is coupled to the first end of the first resistor 111 .

[0071] In this embodiment, the first voltage regulator can maintain a stable voltage output to the battery management circuit within the normal working range, but excessive current may cause the battery management circuit to malfunction. The second resistor is connected in series with the first voltage regulator to limit the current output to the battery management circuit, preventing the battery management circuit from being burned out by excessive current. At the same time, it also avoids the problem of excessive current flowing into the battery management circuit, which causes increased loss in the battery activation circuit.

[0072] In one embodiment, if Figure 4 As shown, the pulse generating circuit 10 further includes a second pulse generating circuit 13. A first end of the second pulse generating circuit 13 is used to couple with the charging power source 50, and a second end of the second pulse generating circuit 13 is coupled with a first end of the activation circuit 12, and the second pulse generating circuit 13 is used to generate a second pulse signal when the charging power source 50 is connected. The activation circuit 12 is also used to convert the second pulse signal into an activation pulse signal.

[0073] In this embodiment, when the second pulse generating circuit is connected to the charging power source, a second pulse signal is generated, and the second pulse signal is converted into an activation pulse signal by the activation circuit, and the activation pulse signal activates the battery management circuit. By generating the second pulse signal when the charging power source is connected, and converting the second pulse signal into an activation pulse signal, it is possible to avoid continuously generating the activation pulse signal after the charging power source is connected, thereby reducing the power consumption of the battery activation circuit.

[0074] Exemplarily, the charging power source 50 may be provided by a charging device external to the cleaning device.

[0075] In one embodiment, if Figure 5 As shown, the second pulse generating circuit 13 includes a third resistor 131 and a second capacitor 132. The first end of the third resistor 131 is used to couple with the charging power source 50, and the second end of the third resistor 131 is coupled with the first end of the activation circuit 12. The second capacitor 132 is coupled with the third resistor 131 in parallel.

[0076] In this embodiment, since the second capacitor has a high response capability to the rate of change of voltage, the voltage of the second capacitor will be instantaneously higher than the input voltage at the moment of charging the second capacitor. Therefore, when the first charging power supply is connected, the voltage of the second capacitor begins to rise. Since the second capacitor is coupled in parallel with the third resistor, the voltage of the second capacitor will rise instantaneously and be higher than the voltage of the charging power supply to generate a second pulse signal. The second pulse signal is converted into an activation pulse signal by the activation circuit, and the battery management circuit is activated after receiving the activation pulse signal. As the voltage of the second capacitor reaches a peak value, the voltage of the second capacitor gradually decreases to the voltage of the charging power supply. Since there is no activation pulse signal in the battery activation circuit at this time, the battery management circuit will not be activated. The whole process shows that the second pulse signal is a signal that rises first and then falls, so the activation pulse signal transmitted to the battery management circuit will be converted from a high level to a low level. This can effectively reduce the power consumption generated by the battery activation circuit activating the battery management circuit.

[0077] For example, if the battery management circuit 20 is to be activated again after the charging power source 50 is connected, the battery management circuit 20 can only be activated again by connecting the charging power source 50 again to generate a new second pulse signal.

[0078] In one embodiment, if Figure 5 As shown, the second pulse generating circuit 13 further includes a second step-down circuit 133. A first end of the second step-down circuit 133 is used to couple with the charging power source 50, a second end of the second step-down circuit 133 is coupled with a first end of the third resistor 131, and the second step-down circuit 133 is used to reduce the voltage of the charging power source 50.

[0079] In this embodiment, the second step-down circuit can reduce the voltage of the charging power supply to a safe voltage range acceptable to the battery management circuit, which can protect the battery management circuit from damage on the one hand and reduce the power loss in the battery activation circuit on the other hand.

[0080] In one embodiment, if Figure 5 As shown, the second voltage-reducing circuit 133 includes a second voltage-stabilizing tube 134 . The cathode of the second voltage-stabilizing tube 134 is used to couple with the charging power source 50 , and the anode of the second voltage-stabilizing tube 134 is coupled with the first end of the third resistor 131 .

[0081] In this embodiment, the second voltage regulator is connected in series between the charging power source and the third resistor, so as to reduce the output voltage of the charging power source to a safe voltage range acceptable to the battery management circuit, thereby playing a voltage reduction function. Moreover, since the voltage at both ends of the second voltage regulator is stable when the second voltage regulator is reversely broken down, the second pulse circuit can be kept stable, thereby improving the reliability of the battery activation circuit.

[0082] Exemplarily, the second step-down circuit 133 may include, in addition to the second voltage regulator tube 134 , a plurality of second diodes coupled in series.

[0083] In one embodiment, if Figure 5 As shown, the second pulse generating circuit 13 further includes a fourth resistor 135 . A first end of the fourth resistor 135 is coupled to the anode of the second voltage regulator tube 134 , and a second end of the fourth resistor 135 is coupled to the first end of the third resistor 131 .

[0084] In this embodiment, the second voltage regulator can maintain a stable voltage output to the battery management circuit within the normal working range, but excessive current may cause the battery management circuit to malfunction. The fourth resistor is connected in series with the second voltage regulator to limit the output to the battery management circuit, preventing the battery management circuit from being burned out by excessive current. At the same time, it also avoids the problem of excessive current flowing into the battery management circuit, which causes increased loss in the battery activation circuit.

[0085] In one embodiment, if Figure 3 , Figure 5 , Figure 6 As shown, the activation circuit 12 includes a voltage divider circuit 121 and a filter circuit 122. The first end of the voltage divider circuit 121 is coupled to the second end of the pulse generating circuit 10, the second end of the voltage divider circuit 121 is used to couple to the ground terminal 60, and the third end of the voltage divider circuit 121 is coupled to the first end of the battery management circuit 20. The filter circuit 122 is coupled in parallel between the first end and the second end of the voltage divider circuit 121.

[0086] In this embodiment, the voltage divider circuit can reduce the voltage input to the battery management circuit to a suitable operating range to protect the battery management circuit from being damaged by excessive input voltage, and the filter circuit can perform a filtering function to prevent the battery management circuit from being activated by mistake.

[0087] Exemplarily, the voltage divider circuit 121 may include a fifth resistor 1211 and a sixth resistor 1212. The first end of the fifth resistor 1211 is coupled to the second end of the pulse generating circuit 10, the second end of the fifth resistor 1211 is coupled to the first end of the sixth resistor 1212, the second end of the fifth resistor 1211 is coupled to the first end of the battery management circuit 20, and the second end of the sixth resistor 1212 is used to couple to the ground terminal 60. The filter circuit 122 may include a third capacitor 1221. The first end of the third capacitor 1221 is coupled to the first end of the fifth resistor 1211, and the second end of the third capacitor 1221 is coupled to the second end of the sixth resistor 1212. When the pulse generating circuit 10 does not generate an activation pulse signal, the ground terminal 60 pulls down the voltage of the first end of the battery management circuit 20 to a low level.

[0088] Exemplarily, the first resistor 111 is greater than the sixth resistor 1212 , and the third resistor 131 is greater than the sixth resistor 1212 .

[0089] In one embodiment, if Figure 6 As shown, the battery activation circuit further includes a charging transistor 70 and a discharging transistor 80. The first terminal of the charging transistor 70 is used to couple with the positive electrode of the battery 30, the second terminal of the charging transistor 70 is used to couple with the charging power source 50, and the control terminal of the charging transistor 70 is coupled with the second terminal of the battery management circuit 20. The first terminal of the discharging transistor 80 is used to couple with the ground terminal 60, the second terminal of the discharging transistor 80 is used to couple with the load 90, and the control terminal of the discharging transistor 80 is coupled with the third terminal of the battery management circuit 20.

[0090] In this embodiment, when the battery needs to be charged, the battery management circuit controls the charging transistor to work, and the charging transistor controls the current to flow from the charging power source to the battery. When the battery needs to be discharged, the battery management circuit controls the discharge transistor to work, and the current flows from the battery to the load. By controlling the charging transistor and the discharge transistor through the battery management circuit, the operation mode of the cleaning device can be adjusted, thereby reducing the power consumption of the cleaning device.

[0091] Exemplarily, the first terminal of the battery management circuit 20 may be a wake-up terminal, the second terminal may be a first input-output terminal, and the third terminal may be a second input-output terminal.

[0092] Exemplarily, the cleaning device further includes a second switch. The second switch is coupled to the load 90 and is used to control the load 90 to run or stop running. When the first switch 40 is closed, if the load is not controlled to run by the second switch within the delay time, the battery management circuit 20 controls the discharge transistor 80 to be disconnected so that the cleaning device runs in a low power consumption mode.

[0093] Exemplarily, when the pulse generating circuit 10 does not generate an activation pulse signal, the first end of the battery management circuit 20 is a low-level signal provided by the ground terminal 60, and the battery management circuit 20 is in an inactive state. When the pulse generating circuit 10 generates an activation pulse signal, the first end of the battery management circuit 20 receives a short high-level signal, and the battery management circuit 20 is activated. During the delay time, if the second switch is activated, the battery management circuit 20 enters the working state. Alternatively, if the activation pulse signal is generated by the charging power supply 50, the battery management circuit 20 is activated when the charging power supply 50 is in the connected state. When the battery 30 needs to be charged, the battery management circuit 20 controls the charging transistor 70 to work, and the charging transistor 70 controls the current to flow from the charging power supply to the battery 30; when the battery 30 needs to be discharged, the battery management circuit 20 controls the discharge transistor 80 to work, and the discharge transistor 80 controls the current to flow from the battery 30 to the load 90. When the charging and discharging processes of the battery 30 are completed, if the battery management circuit 20 cannot detect the charging current and the discharging current within a certain period of time, the battery management circuit 20 will control the charging transistor 70 and the discharging transistor 80 to be disconnected to enable the cleaning device to enter a low power consumption mode.

[0094] Combination Figures 1 to 6 , the working principle of the battery activation circuit is described in detail:

[0095] When the first switch 40 is closed, the voltage at the positive electrode of the battery 30 is connected to the battery activation circuit. Since the voltage at the positive electrode of the battery 30 is higher than the reverse breakdown voltage critical value of the first voltage regulator tube 114, the first voltage regulator tube 114 will reduce the voltage of the battery 30 to a safe voltage range. The voltage signal of the first voltage reduction will be converted into an instantaneous high-level signal after passing through the first resistor 111 and the first capacitor 112. The instantaneous high-level signal will be converted into an activation pulse signal after being divided by the activation circuit 12, and the battery management circuit 20 will be activated after receiving the activation pulse signal at a high level.

[0096] When the second pulse generating circuit 13 is coupled to the charging power supply 50, the voltage of the charging power supply 50 is connected to the battery activation circuit. Since the voltage of the charging power supply 50 is higher than the reverse breakdown voltage critical value of the second voltage regulator tube 134, the second voltage regulator tube 134 will reduce the voltage of the charging power supply 50 to a safe voltage range. The voltage signal of the first voltage reduction will be converted into an instantaneous high-level signal after passing through the third resistor 131 and the second capacitor 132. The instantaneous high-level signal will be converted into an activation pulse signal after being divided by the activation circuit 12, and the battery management circuit 20 will be activated after receiving the activation pulse signal.
