[0025] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0026] The terms "first", "second", and the like in the description and in the claims of the present application and above drawings are used for distinguishing between similar objects talking about the application and not necessarily for describing a specific sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and embodiments of the application. Moreover, the terms "comprise", "comprising", "include", "including", and the like are to be construed in an inclusive manner, that is as "including but not limited to". Furthermore, the terms "a", "an", and the like are not intended to be construed in a limiting sense. For example, the use of the terms "a" and "an" to refer to a plurality of elements is intended to be construed as "at least one" and "one or more", respectively.

[0027] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all directed to the same embodiments, or alternative or alternative embodiments.

[0028] The electronic device related to the embodiments of the present application can include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to wireless modems with wireless communication functions, and various forms of user equipment (UE), mobile stations (MS), terminal devices, etc.

[0029] First, the system to which the embodiments of the present application are applied is described. Please refer to Figure 1 , Figure 1 A charging and discharging system provided by the embodiments of the present application, such as Figure 1As shown, the system includes a first device 101, a second device 102 and a connector 103, wherein the first device 101 can work when the connector 103 is connected with the second device 102. That is, the use of the first device 101 depends on the connection with the second device 102, and the connection between the first device 101 and the second device 102 is realized through the connector 103. When the first device 101 is connected with the connector, the connector 103 can supplement the power for the first device 101, and when the connector 103 is connected with the second device 102, the connector 103 can supplement the power through the second device 102. The connector 103 can be connected with the first device 101 or the second device 102 alone, or can be connected with the first device 101 and the second device 102 at the same time. The connection between the connector and the first device and the second device can be wired connection or wireless connection. For example, the connector includes two connection lines on both sides, which can be connected with the first device and the second device respectively. Or the connector is connected with the first device by wire and connected with the second device wirelessly. Or the connector is connected with the second device by wire and connected with the first device wirelessly. The first device can be a laser pointer, and the second device can be a computer. The connector is connected with the computer through the USB interface, and then the computer transmits and receives signals between the connector and the laser pointer. Or the first device can be a car key accessory, and the second device can be a car machine, for example, a power supply device on a vehicle. The connector can be a wired or wireless connection device between the car key accessory and the car machine. In the case that the car machine is connected with the connector, the car key can be charged. Or the first device can also be an induction board, which is connected with a computer through a connector. The content projected on the screen by the computer can be removed by the induction board. Or the first device can also be a wearable device, and the second device can be a game console. Since the first device and the second device are wirelessly connected through the connector, the first device cannot be used while charging in general, and in fact, using the device while charging will also have adverse effects on the performance of the battery. In this case, the charging of the first device needs to be prompted, and different degrees of charging are performed according to different situations.

[0030] It should be noted that the present application mainly discusses the charging and discharging of the first device and the second device, and therefore does not emphasize that the "connection" for "communication connection" refers to a connection that can charge or discharge, and does not discuss whether communication connection is performed at the same time.

[0031] Please refer to Figure 2A , Figure 2A The embodiment of the present application provides a method flow chart for charging and discharging of a charging and discharging system, which comprises the following steps:

[0032] S201, the first device is connected with the connector to supplement the power through the connector;

[0033] S202, the second device, establishes a connection with the connector, and supplements the power of the connector;

[0034] S203, the connector, determines the supplement power and / or the discharge power according to the connection state with the first device and / or the second device, and the state parameters of the connector, the first device and / or the second device.

[0035] In the embodiments of the present application, the first device is a laser pointer, the second device is a computer, the first device is a car key, and the second device is a charging device in a vehicle.

[0036] When the laser pointer is connected with the connector, the power of the laser pointer can be supplemented through the connector. When the connector is connected with the computer, the power of the connector can be supplemented through the computer. That is to say, both the laser pointer and the connector contain batteries, and the voltage of the battery in the laser pointer is less than the voltage of the battery in the connector, and the voltage of the USB interface of the computer is the highest. The batteries in the laser pointer and the connector can be lithium batteries or lead-acid storage batteries, etc. When the connector is connected with the laser pointer, how to charge the laser pointer is determined by the connector according to the state parameters of the connector and / or the state parameters of the laser pointer. When the connector is connected with the USB interface of the computer, how to charge the connector is determined by the connector according to the state parameters of the connector and / or the state parameters of the computer. The state parameters include the amount of contained power, the connection time, the distance, the working time, etc., which are determined according to different situations.

[0037] Similarly, the power supply device in the vehicle and the car key can be wirelessly charged or connected through the connector. The connector itself contains a storage battery and can be charged and discharged. When the car key is within the range of the vehicle, the power of the power supply device can be obtained through the connector. When the car key is outside the range of the vehicle, the connector can also be taken out of the vehicle at the same time and carried together with the car key, and the car key can be charged. Avoid sudden power failure during use of the car key.

[0038] As can be seen, in the embodiments of the present application, the supplement power and / or the discharge power are determined by the connector according to the connection state with the first device and / or the second device, and the state parameters of the connector, the first device and / or the second device, which improves the intelligence of the power supplement of the charging and discharging system, and further improves the working efficiency of the charging and discharging system.

[0039] Optionally, when the connector is connected to both the first and second devices simultaneously, the status parameter acquired by the connector is the connection duration. The connector is used to: discharge power to the first device when the duration of connection between the connector and the first device alone is less than a first preset duration; replenish power from the second device when the duration of connection between the connector and the second device alone is less than a second preset duration; and stop discharging power to the first device and stopping replenishing power from the second device when the duration of connection between the connector and both devices simultaneously is greater than a third preset duration. The third preset duration is less than or equal to the minimum of the first and second preset durations.

[0040] Please see Figure 2B , Figure 2B This is a schematic diagram of a discharge / reception system connection provided in an embodiment of this application, as shown below. Figure 2B As shown, the first device is a laser pointer, and the second device is a computer. The connector connects to the computer via a USB interface and uses technologies such as Bluetooth for signal transmission. Through digital radio frequency technology, it achieves short-range communication with the laser pointer with sufficient bandwidth. The connector can connect to both the first and second devices simultaneously, including wired or wireless connections. For example, the connector may include connecting cables on both sides, allowing simultaneous connection to both the computer and the laser pointer. Alternatively, the connector can be wired to the computer and wirelessly connected to the laser pointer. It is also possible for the connector to be wired to the laser pointer and wirelessly connected to the computer.

[0041] Or, see Figure 2C , Figure 2C This is another schematic diagram of the discharge / reception system connection provided in an embodiment of this application, as shown below. Figure 2C As shown, the first device is a car key, the second device is a power supply device in the vehicle, and the connector is a wireless charging device. The connector can be configured to wirelessly charge the power supply device within a preset distance, such as within the vehicle's interior space. When the connector is inside the vehicle, it can be charged via the power supply device; when the connector is connected to the car key, it can charge the car key.

[0042] The connector connects to both the first and second devices simultaneously, but the timing of the connection establishment with both devices can be the same or different. Please refer to [link / reference] for details. Figure 2D , Figure 2D This application provides a schematic diagram illustrating the simultaneous connection of a connector with a first device and a second device, as shown in the embodiments of this application. Figure 2DAs shown, the first device is connected with the connector at t1, the second device is connected with the connector at t2, and t1 is later than t2. Because the connector is connected with the first device and the second device at the same time, that is, the connector is charging and discharging at the same time, in some cases, the connector has been connected with one of the first device or the second device for a period of time, and the charging or discharging may be almost completed, but due to the device connected later, the charging or discharging cannot be completed completely. If the charging and discharging are performed without time limit, unnecessary damage to the connector may be caused. Therefore, when it is determined that the connector is connected with the first device and the second device at the same time, the time T0 that the first device is connected with the connector alone is obtained, as shown in the following formula: Figure 2C T0 = T1-t1, and the time T0' that the second device is connected with the connector alone is obtained, as shown in the following formula:

[0043] In some cases, the time when the connector is connected with the first device and the second device may be relatively close, so that the actual power of the connector is kept in a balanced state, but the first device may have completed charging, and the second device may have insufficient power to release. Based on this, the time when the connector is connected with the first device and the second device at the same time can be limited. As shown in the following formula: Figure 2D The time when the connector is connected with the first device and the second device at the same time is the time when the device connected later is connected with the connector, that is, the time T0" when the first device and the second device are connected at the same time = T1-t1. If T0" is greater than a third preset time, the connector stops discharging power to the laser pointer and stops supplementing power from the computer. In order to release the work of the connector in time. The third preset time is less than or equal to the minimum value of the first preset time and the second preset time, because in the case that the time when the first device and the second device are connected with the connector is relatively close, it is difficult to achieve that the time when the connector is connected with one of the devices alone is greater than the first preset time or the second preset time, so when the time when the first device and the second device are connected with the connector at the same time is greater than the third preset time, the charging and discharging process of the connector is also cut off. Further reduce unnecessary damage to the connector.

[0044] Optionally, when the connector is connected with the first device alone, the state parameter includes a power parameter, and the connector is configured to: when the power parameter of the first device is less than a first preset power, the connector supplements power for the first device; and when the power parameter of the first device is greater than or equal to the first preset power, the connector stops supplementing power for the first device.

[0045] The first device is a chargeable device, and the power parameter of the battery of the first device can be acquired by the connector when the connector is in communication with the first device. Then the connector determines whether to charge the laser pointer according to the power parameter. If the power of the first device is less than a first preset power, the connector continues to charge the first device. Otherwise, the connector stops charging the first device. The first preset power can be, for example, 99% power, 90% power, etc. In this way, when the user stops charging the first device, there is enough power in the first device. At the same time, the battery in the first device is not continuously charged, which can cause damage to the battery.

[0046] Optionally, the state parameter further comprises a connection time interval of the connector and the first device. The connector is configured to: when the connection time interval of the connector and the first device is less than a first preset interval, adjust the first preset power to a second preset power, the second preset power being greater than the first preset power; and when the power parameter of the first device is greater than or equal to the second preset power, the connector stops charging the first device.

[0047] The connection time interval of the first device is the time when the connector is last disconnected from the first device to the time when the connector is next connected to the first device. If the connection time interval of the connector and the first device is short, it means that the user is frequently charging the first device. Then the first preset power is adjusted to the second preset power, and the second preset power is greater than the first preset power, which means that the laser pointer needs to be charged all the time, and the charging is stopped when the power reaches a higher preset value than before. For example, the first preset power is originally 90%, that is, the power of the laser pointer reaches 90% and the charging is stopped. But the second preset power is increased to 95%, which means that the charging is stopped when the power of the laser pointer reaches 95%. In this way, enough power can be provided for the first device that is frequently used.

[0048] Optionally, when the connector is only connected to the second device, the state parameter comprises the power parameter. The connector is configured to: when the power parameter of the connector is less than a third preset power, the connector charges from the second device; and when the power parameter of the connector is greater than a fourth preset power, the connector stops charging from the second device, the fourth preset power being greater than the third preset power.

[0049] When the connector is only connected with the second device and not connected with the first device, that is, the connector only charges and does not discharge. When the power parameter of the connector is less than a third preset power, the computer needs to supplement the power of the connector, and when the power parameter of the connector is greater than a fourth preset power, the connector stops charging. For example, the third preset power is 80%, and the fourth preset power is 90%. If the power of the connector is less than 80% when the connector is connected with the second device, charging is performed. If the power of the connector is greater than 90% when the connector is connected with the second device, charging is not performed. If the power of the connector is charged from 70% to 80% when the connector is connected with the second device, since the power is not 90%, charging is not stopped, and the connector can be charged to 90%. If the power of the connector is between 80% and 90% when the connector is connected with the second device, since the power is not less than 80%, charging is not performed. That is, when the power of the connector is greater than or equal to the third preset power and less than the fourth preset power, the connector can be charged or can not be charged. This is related to whether the connector is charged from low power to high power or directly connected with the second device at high power. The power range is the buffer stage of the connector. In this way, the connector can be prevented from frequently switching between charging and non-charging when the power is at a critical value, and unnecessary consumption of the connector is reduced.

[0050] Optionally, when the connector is disconnected from the first device and the second device, the connector is further configured to: determine distances between the connector and the first device and the second device; and when the distance between the connector and the first device is greater than a first preset distance and the distance between the connector and the second device is greater than a second preset distance, the connector sends first prompt information for prompting connection of the connector and the second device.

[0051] The connector is disconnected from the first device and the second device, but the first device can still need to be charged. In this case, charging prompting needs to be performed. In the embodiment of the present application, when the distance between the connector and the first device is greater than a first preset distance and the distance between the connector and the second device is less than a second preset distance, the first preset distance is a charging distance between the connector and the first device, and greater than the first preset distance indicates that the first device is in a non-charging state and can be in a handheld working state. The second preset distance is a charging distance between the connector and the second device, and greater than the second preset distance indicates that the connector is also in a non-charging state. If the first device is in a non-charging state (or a working state), the first device can need to be charged in the next time, and the connector does not timely charge, which can cause the connector to not provide enough power for the first device in the future. Therefore, the connector needs to send first prompt information for prompting connection of the connector and the second device to supplement the power.

[0052] Optionally, the first prompt information is silent prompt information, such as light flickering, or vibration, etc. Because the laser pointer is usually used in a serious occasion such as a classroom or a meeting, the sound prompt may cause bad influence on the application occasion. Or the car key is usually placed in a dark bag, and the prompt is performed through the light flickering lamp, so that the user can quickly find the car key and check it. The silent prompt information can play a prompt effect while giving a better use experience.

[0053] When the first device is a laser pointer and the second device is a computer, the connection of the computer and the connector includes two kinds of connections, one is a communication connection, and the other is a charging connection. In the case of the communication connection of the computer and the connector, the communication connection of the computer and the laser pointer can be realized. Therefore, when the laser pointer is in a use state, the computer and the connector are always in a communication connection state, but the computer and the connector are not necessarily in a charging connection state. Based on this consideration, when the computer and the connector are in communication connection, the connection of the computer and the connector can be opened to the charging connection state at any time. Therefore, the method can further include: obtaining the power-off speed of the first device, the power-off speed including a first power-off speed, a second power-off speed and a third power-off speed, wherein the first power-off speed corresponds to the open but idle state of the first device, the second power-off speed corresponds to the indirect key state of the first device, and the third power-off speed corresponds to the long key state of the first device; matching the power-off speed of the first device with the power-off speed-charge speed mapping table to determine the charge speed corresponding to the power-off speed of the first device; determining whether the charging connection state of the connector should be opened according to the charge speed, and controlling the charge speed of the connector.

[0054] After the charging connection state of the connector and the computer is opened, the corresponding charge speed of the connector can include waiting for charging, constant-speed charging and fast charging. If it is the charge speed corresponding to the first power-off speed in the mapping table, the charge speed of the connector can be waiting for charging, that is, not formally charging, entering a charging waiting state, and being switched into a normal charging state at any time; if it is the charge speed corresponding to the second power-off speed in the mapping table, the charge speed of the connector can be constant-speed charging, that is, the indirect key state of the laser pointer, the demand for charging is generally strong, and the connector can also be charged at a constant speed to prepare the power for the laser pointer. If it is the charge speed corresponding to the third power-off speed in the mapping table, the charge speed of the connector can be fast charging, that is, the long key state of the laser pointer, the demand for charging is very strong, and the connector fast charges to prepare power for the laser pointer, so that there is enough power for the laser pointer when the laser pointer and the connector are connected.

[0055] In the embodiment of the present application, by determining the different charging speed requirements of the first device through the different power-off speeds of the first device, and then determining the different power supply speeds of the connector, the charger can supply power at a reasonable speed, on the one hand, sufficient power can be prepared for the first device, and on the other hand, the connector will not be damaged too much due to excessive power supply, thereby prolonging the service life of the connector.

[0056] Please refer to Figure 3 , Figure 3 is another method flowchart for charging and discharging provided by the embodiment of the present application, as shown in Figure 3 , the method comprises the following steps:

[0057] S301, the first device establishes a connection with the connector, and supplements power through the connector;

[0058] S302, the second device establishes a connection with the connector, and supplements power to the connector;

[0059] S303, the connector is connected with the first device and the second device at the same time, when the time length of the connection between the connector and the first device alone is less than the first preset time length, the connector discharges power to the first device;

[0060] S304, when the time length of the connection between the connector and the second device alone is less than the second preset time length, the connector supplements power from the second device;

[0061] S305, when the time length of the connection between the connector and the first device and the second device at the same time is greater than the third preset time length, the connector stops discharging power to the first device and stops supplementing power from the second device, and the third preset time length is less than or equal to the minimum value of the first preset time length and the second preset time length.

[0062] The implementation of the above steps can refer to the corresponding description of Figures 2A-2C , which will not be described here.

[0063] As can be seen, in the embodiment of the present application, a charging and discharging method of a charging and discharging system is provided, which comprises: the connector is connected with the first device and the second device at the same time, when the time length of the connection between the connector and the first device alone is less than the first preset time length, the connector discharges power to the first device; when the time length of the connection between the connector and the second device alone is less than the second preset time length, the connector supplements power from the second device; and when the time length of the connection between the connector and the first device and the second device at the same time is greater than the third preset time length, the connector stops discharging power to the first device and stops supplementing power from the second device. In this process, whether to disconnect the charging connection is determined according to the time length of the separate connection between the connector and the first device and the second device, which can ensure that the duration of the simultaneous charging and discharging process of the connector will not be infinitely prolonged, thereby reducing unnecessary damage to the connector.

[0064] Please refer to Figure 4 , Figure 4 is another charging and discharging method flow chart of a charging and discharging system provided by the embodiment of the application, as shown in the figure, the method comprises the following steps: Figure 4

[0065] S401, the first device establishes a connection with the connector, and supplements the power through the connector;

[0066] S402, the second device establishes a connection with the connector, and supplements the power to the connector;

[0067] S403, when the connector is disconnected with the first device and the second device, the connector determines the distance between the connector and the first device and the second device;

[0068] S404, when the distance between the connector and the first device is greater than the first preset distance, and the distance between the connector and the second device is greater than the second preset distance, the connector sends a first prompt information for prompting to connect the connector with the second device.

[0069] The implementation of the above steps can refer to the corresponding description of Figures 2A-2C , which will not be repeated here.

[0070] It can be seen that in the embodiment of the application, a charging and discharging method of a charging and discharging system is provided, which comprises: when the connector is disconnected with the first device and the second device, the connector determines the distance between the connector and the first device and the second device; when the distance between the connector and the first device is greater than the first preset distance, and the distance between the connector and the second device is greater than the second preset distance, the connector sends a first prompt information for prompting to connect the connector with the second device. The process is used to timely prompt the connector to supplement the power, and reduce the probability that the connector cannot provide enough power for the laser pen due to not timely charging.
