Description

Technical Field

[0001] The present invention relates to the technical field of smart door locks, and in particular to a battery charging method, device, equipment, medium, program product and a smart lock. Background Art

[0002] In daily life, when the smart lock installed on the entrance door or safe is low on power, it will sound an alarm, but the user may forget to replace the battery or forget to charge it because of other things, so the next time the door is opened, the smart lock cannot be opened due to low power. Take the smart lock installed on the entrance door as an example. If the user is in a hurry to go out when the smart lock is low on power, it is possible that the battery power will no longer be able to support the lock to open the door and the door cannot be opened electronically when the user returns home next time. At this time, an external mobile power supply is required, and charging outside the door can pass the electronic verification to open the door. If the user does not bring an external mobile power supply, the mechanical key is required to manually open the door. After opening the door, remove the battery to charge it, or replace the battery. And after removing the battery and charging it, you may forget to put the battery back into the smart lock, which will cause the door to be unable to be powered on when it is opened again. An external mobile power supply or manual mechanical door opening is still required, which greatly reduces the user's experience of the smart lock. Summary of the invention

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] The embodiment of the present invention is applicable to the scenario of charging the battery in the smart lock installed in the device such as the entrance door or the safe. The embodiment of the present invention provides a battery charging method, which achieves the effect of automatically charging and disconnecting the battery according to the battery power by deploying a charger in the smart lock.

[0040] According to an embodiment of the present invention, a battery charging method embodiment is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0041] In this embodiment, a battery charging method is provided, which can be used for the above-mentioned smart lock. Figure 1 is a flow chart of a battery charging method according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0042] Step S101, when a door closing signal is received, a first battery power level is obtained.

[0043] Specifically, in the embodiment of the present invention, taking the smart lock installed at the entrance door as an example, the smart lock selected by the user is pre-installed with a battery and a charger, and the charger is connected to an external power source. The charger and the battery can be wirelessly charged through a coil, or wired charged through a USB port or other electronic terminals, etc., which are not limited here. Moreover, the battery is still set to be detachable, so that the user can remove the battery according to their own needs.

[0044] In some optional implementations, after the smart lock is installed and powered on for initialization, the battery provides power to the smart lock, and combines sensor technology and lock working identification technology to detect and identify the standby state of the smart lock in real time. When it is detected that the user is opening or closing the door, the control module controls the lock tongue and other components to open or close the door, thereby realizing the conversion of the smart lock to the standby state. In order to accurately grasp the current power of the battery and avoid the inability to open the door due to the battery being too low, after receiving the door closing signal, the charger or other special power detection device detects the current power of the battery in the smart lock to obtain the first power. In addition, the charger or other special power detection device can also calculate the current health of the battery based on the detection situation. The specific calculation method is a conventional technical means in this field and will not be repeated here.

[0045] Step S102, judging whether charging is required according to the first power level and a preset minimum power level threshold, and if charging is required, controlling the charger to charge the battery.

[0046] Specifically, in an embodiment of the present invention, a preset minimum power threshold is pre-stored in the smart lock. By comparing the first power level with the minimum power threshold, it can be determined whether the battery needs to be charged at this time. That is, after determining that the first power level is lower than the minimum power threshold, it means that the battery is in a low power state at this time. If it is not charged in time, the smart lock may be shut down due to low power, and the user cannot enter the door without a mechanical key and an external mobile power supply. Therefore, when the embodiment of the present invention determines that the first power level is lower than the minimum power threshold when the door is closed, it determines that the smart lock needs to be charged at this time, and triggers the charging program, and controls the charger to charge the battery in the closed state, thereby ensuring that the smart lock is always in a standby state.

[0047] Step S103, during the charging process, obtaining a second power level of the battery.

[0048] Specifically, in the embodiment of the present invention, in order to avoid battery overcharge, during the charging process, the charger or other special power detection device detects the current power of the battery in the smart lock to obtain the second power. At this time, as the charging time increases, the second power will gradually increase.

[0049] Step S104, judging whether charging needs to be terminated according to the second power level and the preset maximum power level threshold, and if charging needs to be terminated, controlling the charger to cut off power to the battery.

[0050] Specifically, in an embodiment of the present invention, a preset maximum power threshold is pre-stored in the smart lock. By comparing the second power with the maximum power threshold, it can be determined whether the battery needs to end charging at this time. That is, after determining that the second power is higher than the maximum power threshold, it means that the battery is in a high power state at this time. If charging is not terminated in time, it may cause battery overcharge, thereby affecting the health and service life of the battery. Therefore, when the embodiment of the present invention determines that the second power is higher than the maximum power threshold during charging, it determines that the smart lock needs to end charging at this time, and controls the charger to cut off the power to the battery when the door is closed, thereby ensuring that the smart lock is always in the best power state.

[0051] The battery charging method provided by the present invention determines whether charging is required according to the first power level of the battery and the preset minimum power level threshold after receiving the door closing signal, and controls the charger in the smart lock to charge the battery if necessary, and determines whether charging needs to be terminated according to the second power level of the battery and the preset maximum power level threshold during the charging process, and controls the charger to cut off the power to the battery if necessary. The present invention can automatically charge according to the power level of the battery by controlling the charger to charge and cut off the power of the battery, without the need to manually plug and unplug the battery or connect an external mobile power supply, thereby avoiding the user being unable to enter the door due to the battery being too low, and also avoiding overcharging or over-discharging of the battery, thereby improving the health of the battery, extending the service life of the battery, and improving the user experience and satisfaction.

[0052] In this embodiment, a battery charging method is provided, which can be used for the above-mentioned smart lock. Figure 2 is a flow chart of a battery charging method according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0053] Step S201, obtaining a preset charging mode, which includes an automatic charging mode and an active charging mode, and determining whether the charging mode is an automatic charging mode; if it is an automatic charging mode, obtaining a preset minimum power threshold and a preset maximum power threshold.

[0054] Specifically, in the embodiment of the present invention, the smart lock is pre-set with automatic charging mode and active charging mode. The user can select the mode through the display interface of the smart lock or the corresponding APP. Before each power detection, the smart lock will obtain the charging mode currently set by the user, such as Figure 3 shown.

[0055] In some optional implementations, the automatic charging mode is that the smart lock automatically detects the battery power and automatically determines whether charging and power off are required. In this mode, the system is pre-set with a default minimum power threshold and a maximum power threshold during development. During the use of the smart lock, the user can also set the minimum power threshold or the maximum power threshold through the display interface of the smart lock or the corresponding APP, so that on the basis of automatic charging according to the battery power, the user can be provided with the choice of personalized function settings, and the user can set the power threshold according to personal habits to improve the user experience.

[0056] In some optional embodiments, such as Figure 3 As shown, if the charging mode set by the user is the active charging mode, the smart lock will not actively charge or power off the battery. At this time, the user needs to operate on the display interface of the smart lock or the corresponding APP to select charging or power off. The smart door lock obtains the corresponding charging signal or power-off signal, and controls the charger to charge the battery according to the charging signal, or controls the charger to power off the battery according to the power-off signal. In this mode, the charger or other power detection device can still detect the battery power to display the power on the display interface of the smart lock or the corresponding APP, thereby prompting the user whether charging or power off is needed. By setting the active charging mode, the present invention can provide users with more autonomous personalized function setting options. Users can directly control charging or power off according to personal needs, further improving the user experience.

[0057] Step S202: After receiving the door closing signal, obtain the first battery power. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0058] Step S203, judging whether charging is required according to the first power level and a preset minimum power level threshold, and if charging is required, controlling the charger to charge the battery.

[0059] Specifically, the above step S203 includes:

[0060] Step S2031: if the first power level is lower than or equal to the first minimum power level threshold or the second minimum power level threshold, it is determined that charging is required.

[0061] Step S2032: if the first power level is higher than the first minimum power level threshold or the second minimum power level threshold, it is determined that charging is not required.

[0062] Specifically, in the embodiment of the present invention, if the smart lock detects that the user has not set the minimum power threshold and the maximum power threshold, the system default minimum power threshold is used as a benchmark, for example, 5%, and the first power detected when the door is closed is compared with the system default minimum power threshold, such as 5%. Figure 3As shown, if the first power level is lower than or equal to the system default minimum power level threshold, it is determined that charging is required; if the first power level is higher than the system default minimum power level threshold, it is determined that charging is not required.

[0063] In some optional implementations, if it is detected that the user has set a minimum power threshold and a maximum power threshold, the minimum power threshold set by the user is used as a reference, for example, 10%, and the first power detected when the door is closed is compared with the minimum power threshold set by the user. Figure 3 As shown, if the first power level is lower than or equal to the minimum power level threshold set by the user, it is determined that charging is required; if the first power level is higher than the minimum power level threshold set by the user, it is determined that charging is not required.

[0064] Step S204: During the charging process, obtain the second power of the battery. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0065] Step S205, judging whether charging needs to be terminated according to the second power level and the preset maximum power level threshold, and if charging needs to be terminated, controlling the charger to cut off power to the battery.

[0066] Specifically, the above step S205 includes:

[0067] Step S2051: if the second power level is lower than the first maximum power level threshold or the second maximum power level threshold, it is determined that charging does not need to be terminated.

[0068] Step S2052: If the second power level is higher than or equal to the first maximum power level threshold or the second maximum power level threshold, it is determined that charging needs to be terminated.

[0069] Specifically, in the embodiment of the present invention, the minimum power threshold and the maximum power threshold are corresponding, and are both system default thresholds or user-set thresholds. Therefore, if the user does not set the minimum power threshold and the maximum power threshold, the system default maximum power threshold is used as a reference, for example, 80%, and the second power detected during the charging process is compared with the system default maximum power threshold, such as Figure 3 As shown, if the second power level is lower than the system default maximum power level threshold, it is determined that charging does not need to be terminated; if it is higher than or equal to the system default maximum power level threshold, it is determined that charging needs to be terminated.

[0070] In some optional implementations, if the user sets a minimum power threshold and a maximum power threshold, the second power detected during the charging process is compared with the system default maximum power threshold, for example, 85%, based on the maximum power threshold set by the user. Figure 3As shown, if the second power level is lower than the maximum power level threshold set by the user, it is determined that charging does not need to be terminated; if the second power level is higher than or equal to the maximum power level threshold set by the user, it is determined that charging needs to be terminated.

[0071] The battery charging method provided by the present invention determines whether charging is required according to the first power level of the battery and the preset minimum power level threshold after receiving the door closing signal, and controls the charger in the smart lock to charge the battery if necessary, and determines whether charging needs to be terminated according to the second power level of the battery and the preset maximum power level threshold during the charging process, and controls the charger to cut off the power to the battery if necessary. The present invention can automatically charge according to the power level of the battery by controlling the charger to charge and cut off the power of the battery, without the need to manually plug and unplug the battery or connect an external mobile power supply, thereby avoiding the user being unable to enter the door due to the battery being too low, and also avoiding overcharging or over-discharging of the battery, thereby improving the health of the battery, extending the service life of the battery, and improving the user experience and satisfaction.

[0072] In this embodiment, a battery charging method is provided, which can be used for the above-mentioned smart lock. Figure 3 is a flow chart of a battery charging method according to an embodiment of the present invention. Figure 4 As shown, the process includes the following steps:

[0073] Step S401, after receiving the door closing signal, obtain the first battery power. Figure 2 Step S202 of the illustrated embodiment will not be described in detail here.

[0074] Step S402: Determine whether charging is required based on the first power level and the preset minimum power level threshold. If charging is required, control the charger to charge the battery. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0075] Step S403: during the charging process, obtaining a second power level of the battery.

[0076] Specifically, the above step S403 includes:

[0077] Step S4031, detecting whether a door opening signal is received, and if a door opening signal is received, controlling the charger to cut off power to the battery.

[0078] Specifically, in the embodiment of the present invention, in order to avoid charging the battery during power supply, thereby affecting the health and service life of the battery, the standby state of the smart lock is detected in real time during the charging process to see if it changes. Figure 3As shown, when a door opening signal is received in the door closing state, the smart lock needs to control the internal components to perform the corresponding door opening action. The execution of the door opening action requires battery power, so the charger needs to be controlled to stop charging the battery.

[0079] Step S4032, detecting whether a door closing signal is received within a preset time interval, if a door closing signal is received within the preset time interval, returning to the step of controlling the charger to charge the battery.

[0080] Specifically, in the embodiment of the present invention, if the user enters the door normally, the door will be opened and closed in a short time. Figure 3 As shown, if the door closing signal is received again within the preset time interval, the charger is controlled to continue charging the battery, and the battery power is continuously detected during the charging process until the battery power reaches the maximum power threshold and then the charging is terminated. The preset time interval is set according to the user's door opening and closing habits, such as 10s, which is only an example and is not limited thereto.

[0081] Step S4033: if no door closing signal is received within a preset time interval, a prompt message is generated.

[0082] Specifically, in the embodiment of the present invention, if the user forgets to close the door after entering, or does not close the door tightly, such as Figure 3 As shown, the smart lock recognizes that the door is not closed because it does not receive a door closing signal within a preset time interval. At this time, a prompt message is generated to prompt the user through voice playback or APP message of the smart lock. It can be set to prompt the user to close the door, or to prompt the user to remove the battery for charging, which is not limited here.

[0083] Step S404: determine whether charging needs to be terminated based on the second power level and the preset maximum power level threshold. If charging needs to be terminated, control the charger to cut off power to the battery. Figure 2 Step S205 of the illustrated embodiment will not be described in detail here.

[0084] The battery charging method provided by the present invention determines whether charging is required according to the first power level of the battery and the preset minimum power level threshold after receiving the door closing signal, and controls the charger in the smart lock to charge the battery if necessary, and determines whether charging needs to be terminated according to the second power level of the battery and the preset maximum power level threshold during the charging process, and controls the charger to cut off the power to the battery if necessary. The present invention can automatically charge according to the power level of the battery by controlling the charger to charge and cut off the power of the battery, without the need to manually plug and unplug the battery or connect an external mobile power supply, thereby avoiding the user being unable to enter the door due to the battery being too low, and also avoiding overcharging or over-discharging of the battery, thereby improving the health of the battery, extending the service life of the battery, and improving the user experience and satisfaction.
