Description

Technical Field

[0001] This utility model relates to the field of mobile devices, and more specifically, to a charging device. Background Technology

[0002] A homing pigeon tracker is a small yet powerful device primarily used to track the location and flight path of homing pigeons. Specifically, it is widely used in pigeon racing, training, and breeding. In racing, it helps competitors track their pigeons' locations in real time, improving fairness and entertainment value. In training and breeding, it helps pigeon fanciers better manage and care for their pigeons, improving their competitive performance and breeding efficiency. To ensure small size, light weight, and reusability, homing pigeon trackers typically use small, rechargeable polymer lithium batteries. The tracker needs to be charged before each use.

[0003] Pigeon racing involves tens of thousands of pigeons competing simultaneously. To ensure fairness, the pigeon trackers are charged before each race and then fitted to the pigeons. During this process, the pigeon's identifier (ID) and the tracker's ID must be bound one-to-one. This allows the server to locate the pigeon's position based on the information reported by the tracker, preventing confusion. Therefore, after a full charge, it's necessary to find the tracker with the specific ID among thousands of trackers. Current technology typically relies on manual searching, which is time-consuming and labor-intensive. Utility Model Content

[0045] A homing pigeon tracker is a small yet powerful device primarily used to track the location and flight path of homing pigeons. Specifically, it is widely used in pigeon racing, training, and breeding. In racing, it helps competitors track their pigeons' locations in real time, improving fairness and entertainment value. In training and breeding, it helps pigeon fanciers better manage and care for their pigeons, improving their competitive performance and breeding efficiency. To ensure small size, light weight, and reusability, homing pigeon trackers typically use small, rechargeable polymer lithium batteries. The tracker needs to be charged before each use.

[0046] Pigeon racing involves tens of thousands of pigeons competing simultaneously. To ensure fairness, the pigeon trackers are charged before each race and then fitted to the pigeons.

Therefore, after a full charge, it's necessary to find the tracker with the specific ID among thousands of trackers. Current technology typically relies on manual searching, which is time-consuming and labor-intensive.

[0047] This application proposes a charging device to address the aforementioned problems. By incorporating a control unit, a host computer interface, a power supply unit, a display unit, a switch unit, and multiple charging units, the control unit can receive device indication signals via each charging unit and the switch unit, and send these signals to the host computer via the host computer interface. It can also receive display commands from the host computer via the host computer interface and, based on these commands, control the display devices in the display unit corresponding to the charging units connected to the charging device to illuminate. This enables a pigeon tracker charging device with communication capabilities, facilitating communication between the host computer and the charging device, as well as between the charging device and the pigeon tracker. This allows the host computer to communicate with the pigeon tracker through the charging device to locate pigeon trackers with specific IDs, facilitating the identification of such trackers. Furthermore, due to the communication function of the charging device, after the pigeon tracker is fully charged, the host computer can also read the battery status of the pigeon tracker through the charging device for secondary confirmation of whether the tracker is fully charged. Furthermore, the host computer can also check the function of the pigeon tracker through the charging device to ensure that the pigeon tracker can be used in a fully charged and normal state, thus avoiding race accidents caused by insufficient power or equipment failure of the pigeon tracker.

[0048] The charging device provided in this application will be described in detail below with reference to several embodiments.

[0049] Figure 1 This is a schematic diagram of a charging device provided in an embodiment of this application, with reference to... Figure 1 As shown, this embodiment provides a charging device, which includes: a control unit, a host computer interface, a power supply unit, a display unit, a switch unit, and multiple charging units.

[0050] The first end of the control unit is connected to the host computer via the host computer interface, the second end of the control unit is connected to the first end of the display unit, the third end of the control unit is connected to the first end of the power supply unit, and the fourth end of the control unit is connected to the first end of the switch unit.

[0051] Optionally, the control unit can be a micro controller unit (MCU), the host computer can be a personal computer (PC), and the host computer interface can be a Type-C USB interface, so that the MCU can be connected to the USB interface of the host computer through the host computer interface, thereby enabling communication between the charging device and the software in the host computer.

[0052] The second terminal of the power supply unit is connected to the second terminal of the switch unit, the output terminal of the switch unit is connected to the first terminal of each charging unit, and the second terminal of each charging unit is connected to the device to be charged.

[0053] Optionally, the power supply unit is used to manage the power supply of the charging device provided in the embodiments of this application, and the switch unit is used to charge the devices to be charged plugged into each charging unit under the power supply of the power supply unit.

[0054] The display unit includes multiple display devices, and each display device is the same number as each charging unit, and they correspond one-to-one.

[0055] Optionally, the number of charging units can be adjusted according to the actual application. For example, the charging device provided in this application embodiment can be provided with ten charging units, that is, it can charge ten pigeon trackers at the same time. Correspondingly, the display unit is provided with ten display devices.

[0056] Optionally, each display device in the display unit corresponds one-to-one with each charging unit and each device to be charged, so that each display device can, under the control of the control unit, indicate the plugged-in device to be charged.

[0057] The control unit is used to receive device indication signals via each charging unit and switch unit, and to send device indication signals to the host computer via the host computer interface. The device indication signals are used to indicate the identification of the device to be charged plugged into the charging unit.

[0058] Optionally, after each device to be charged is plugged into the charging device, each charging unit can acquire the device identifier and power level of the device to be charged to generate a device indication signal for indicating the device to be charged plugged into the charging unit, and send the generated device indication signal to the control unit so that the control unit can identify the plugged-in device to be charged, and the control unit can send the device indication signal to the host computer through the host computer interface so that the host computer can identify the device identifier and power level of the device to be charged.

[0059] Optionally, the device to be charged is the aforementioned pigeon tracker, or any other mobile device that needs to communicate and locate, such as a cow collar with communication and location functions, or a sheep collar with communication and location functions.

[0060] Optionally, the control unit is also used to periodically control each charging unit to start or stop charging the device plugged into the charging unit via the switching unit.

[0061] Optionally, the control unit is also used to send a power query command for the device to be charged to each charging unit through the switching unit, so as to query the power of each device to be charged during the charging process, and send the obtained power query result to the host computer.

[0062] Optionally, the control unit is also used to send a status query command for the device to be charged to each charging unit through the switching unit, so as to query the operating status of each device to be charged, and send the obtained status query result to the host computer.

[0063] Optionally, the control unit is also used to transmit the received power of each device to be charged to the host computer through the host computer interface, so that the host computer can display the power of each device to be charged.

[0064] The control unit is also used to receive display commands sent by the host computer through the host computer interface, and control the display device in the display unit corresponding to the charging unit of the plugged-in charging device to light up according to the display commands.

[0065] Optionally, since the charging device can communicate with the host computer through the host computer interface, when the user needs to locate a pigeon tracker with a specific ID, the user can generate a display command by operating the host computer, and send the display command to the charging device through the host computer interface. This allows the control unit to receive the display command sent by the host computer through the host computer interface, parse and process the display command, and control the display device in the display unit corresponding to the charging unit plugged into the charging device to light up.

[0066] In other words, the charging device provided in this application embodiment can, after the device to be charged is plugged in, enable the control unit and the host computer to determine the identifier and power of the plugged-in device through the device indication signal, and determine the correspondence between the charging unit, the display device and the device to be charged. Thus, when searching for a pigeon tracker with a specific ID, the display device corresponding to the pigeon tracker with the specific ID can be lit up by the display command, thereby making it easier to find the pigeon tracker with the specific ID.

[0067] In this embodiment, by incorporating a control unit, a host computer interface, a power supply unit, a display unit, a switch unit, and multiple charging units within the charging device, the control unit can receive device indication signals via each charging unit and the switch unit, and send these signals to the host computer via the host computer interface. It can also receive display commands from the host computer via the host computer interface and, based on these commands, control the display devices in the display unit corresponding to the charging units connected to the charging device to illuminate. This enables a pigeon tracker charging device with communication capabilities, facilitating communication between the host computer and the charging device, as well as between the charging device and the pigeon tracker. This allows the host computer to communicate with the pigeon tracker through the charging device to locate pigeon trackers with specific IDs, making it easier to identify such trackers. Furthermore, due to the communication function of the charging device, after the pigeon tracker is fully charged, the host computer can also read the battery status of the pigeon tracker through the charging device to provide a secondary confirmation of whether the pigeon tracker is fully charged. Furthermore, the host computer can also check the function of the pigeon tracker through the charging device to ensure that the pigeon tracker can be used in a fully charged and normal state, thus avoiding race accidents caused by insufficient power or equipment failure of the pigeon tracker.

[0068] Figure 2 This is another schematic diagram of the charging device provided in the embodiments of this application.

[0069] In one possible implementation, refer to Figure 2 As shown, in Figure 1 Based on this, the charging device provided in the embodiments of this application further includes: a protection unit.

[0070] The first end of the protection unit is connected to the host computer interface, the output end of the protection unit is connected to the power supply unit, and the output end of the protection unit is also connected to each charging unit.

[0071] Optionally, the protection unit is used to protect the power input from the host computer interface to prevent the charging device from being burned out due to excessive power. In other words, the power supply from the host computer interface to the charging device can be protected by the protection unit before being output to the power supply unit and each charging unit, thereby achieving a stable power supply to the power supply unit and each charging unit, and thus improving the stability and safety performance of the charging device provided in this application embodiment.

[0072] Figure 3 This is another schematic diagram of the charging device provided in the embodiments of this application.

[0073] In one possible implementation, refer to Figure 3 As shown, in Figure 2 Based on this, the protection unit includes: an overvoltage protection chip.

[0074] The first pin of the overvoltage protection chip is connected to the host computer interface, the second pin of the overvoltage protection chip is connected to the power supply unit, and the other pins of the overvoltage protection chip are connected to each charging unit.

[0075] Optionally, the overvoltage protection chip is used to protect the power input to the host computer interface to prevent the charging device from being burned out due to excessive power.

[0076] Figure 4 This is a schematic diagram of a power supply unit in a charging device provided in an embodiment of this application.

[0077] In one possible implementation, refer to Figure 4 As shown, in Figure 2 Based on this, the power supply unit includes: a first power supply module, a level conversion chip, and a second power supply module.

[0078] The first terminal of the first power module is connected to the output terminal of the protection unit; the second terminal of the first power module is connected to the fifth terminal of the control unit and the second terminal of the display unit; the third terminal of the first power module is connected to the first terminal of the level conversion chip; the second terminal of the level conversion chip is connected to the third terminal of the control unit; the third terminal of the level conversion chip is connected to the second terminal of the switch unit; the fourth terminal of the level conversion chip is connected to the first terminal of the second power module; and the second terminal of the second power module is connected to the output terminal of the protection unit.

[0079] It's understandable that the polymer lithium batteries in pigeon trackers typically have a relatively small capacity, usually around 60-90mAh, and the maximum charging current is usually 30-45mA; the USB interface of the host computer can typically provide a maximum power supply current of 500mA-900mA; therefore, one charging device can usually charge 10 pigeon trackers simultaneously.

[0080] Optionally, when the charging device is charging the device to be charged, the USB interface of the host computer is inserted into the host computer interface to supply power to the charging device. The input power passes through the protection unit to prevent the charging device from burning out other circuits due to incorrect power supply. The power processed by the protection unit is then input to the first power module and the second power module for voltage conversion and regulation to obtain a suitable voltage.

[0081] For example, after voltage regulation by the first power module and the second power module, the first power module outputs a voltage of 3.3V, which can supply the control unit, the switching unit, the level conversion chip and the display module, and the second power module outputs a voltage of 1.8V, which can supply the level conversion chip.

[0082] In one possible implementation, the first power module includes a first low-dropout regulator, and the second power module includes a second low-dropout regulator.

[0083] The first terminal of the first low-dropout regulator is connected to the output terminal of the protection unit; the second terminal of the first low-dropout regulator is connected to the fifth terminal of the control unit and the second terminal of the display unit; the third terminal of the first low-dropout regulator is connected to the first terminal of the level conversion chip; the first terminal of the second low-dropout regulator is connected to the fourth terminal of the level conversion chip; and the second terminal of the second low-dropout regulator is connected to the output terminal of the protection unit.

[0084] By using the first low-dropout regulator and the second low-dropout regulator, the voltage of the power supply output by the host computer can be regulated, ensuring the stability of the output voltage. Even if the input voltage fluctuates, a constant output voltage can be maintained through the internal regulation mechanism, thereby protecting the charging device provided in this application embodiment from the influence of voltage instability.

[0085] Figure 5 This is a schematic diagram of a charging unit in a charging device provided in an embodiment of this application.

[0086] In one possible implementation, refer to Figure 5 As shown, in Figure 1 Based on this, the charging unit includes: a charging management chip, an indicator light, and a charging interface.

[0087] The first end of the charging management chip is connected to the first end of the charging interface, the second end of the charging management chip is connected to the indicator light, and the third end of the charging management chip is also connected to the host computer interface; the second end of the charging interface is connected to the output end of the switching unit, and the third end of the charging interface is connected to the device to be charged.

[0088] The charging management chip is used to control the indicator light to turn on and light up when a device to be charged is detected plugged into the charging interface.

[0089] Optionally, the charging management chip manages the charging process of the device to be charged. Specifically, after receiving power from the host computer, the charging management chip can supply power to the device to be charged through the charging interface. Resistors of different resistance values ​​can also be soldered onto the charging management chip to set the maximum charging current of the device to be charged.

[0090] Optionally, the charging management chip is also used to determine the state of the polymer lithium battery inside the device to be charged, so as to use different charging currents to charge it.

[0091] Optionally, the indicator light is used to display the charging status of the device to be charged. For example, when no pigeon tracker is charging, the indicator light flashes rapidly. When the pigeon tracker is plugged in for charging, the indicator light remains on. When the pigeon tracker's battery is fully charged, the indicator light turns off. The indicator light can be an LED.

[0092] The charging management chip manages the charging process of the device under charging and the indicator light shows the charging status of the device under charging. This ensures that the pigeon tracker can be used in a fully charged and normal state, avoiding race accidents caused by insufficient power or equipment failure.

[0093] Figure 6 This is a schematic diagram of a display unit in a charging device provided in an embodiment of this application.

[0094] In one possible implementation, refer to Figure 6 As shown, in Figure 5 Based on this, each display device in the display unit is connected to the control unit and the power supply unit; the indicator lights of each display device and the corresponding charging unit are located in the same area on the charging device.

[0095] Optionally, the second end of the control unit is connected to each display device to control the lighting of each display device. The display unit is also connected to the power supply unit so that the power supply unit can supply power to each display device.

[0096] Optionally, the indicator lights in each display device and its corresponding charging unit are located in the same area on the charging device to facilitate the identification of a device with a specific ID to be charged. The display device can be a light-emitting diode (LED).

[0097] In one possible implementation, the charging interface includes multiple spring probes.

[0098] Optionally, continue to refer to Figure 6 As shown, a charging interface is a charging slot for a device to be charged. Each charging interface can be equipped with 4 spring probes (pogopins), one of which is the positive terminal of the charging power supply, one of which is the negative terminal of the charging power supply, and the other two are the transmit pin (TX) and receive pin (RX) of the UART communication interface.

[0099] By setting a spring probe in the charging interface, the number of insertion and removal cycles of the charging device provided in this application embodiment can be increased, thereby improving the service life of the charging device provided in this application embodiment. At the same time, the spring probe can also withstand a large current, which can meet the high power requirements of charging multiple devices simultaneously.

[0100] Figure 7 This is a schematic diagram of a switching unit in a charging device provided in an embodiment of this application.

[0101] In one possible implementation, refer to Figure 7 As shown, the switching unit includes multiple dual-channel modular switches; each dual-channel modular switch is cascaded in sequence.

[0102] Optionally, refer to Figure 7 As shown, the switching unit may include multiple dual-channel module switches or other switches. Specifically, different combinations can be obtained depending on the number of devices to be charged. Figure 7 The following is an example using 10 devices waiting to be charged.

[0103] It is understandable that the switching unit is used to solve the problem of insufficient serial ports of the control unit. In the switching unit, time-sharing communication can be performed through the control unit, so that communication with multiple devices to be charged can be achieved using one serial port of the control unit.

[0104] Optionally, continue to refer to Figure 7 As shown, the dual-channel module switches are cascaded in sequence. The first-stage dual-channel module switch can be connected to the output terminal of the control unit, and the last-stage dual-channel module switch can be connected to the charging interface in the charging unit. This allows the control unit to control the conduction of each dual-channel module switch in the switching unit through the general purpose input / output (GPIO) interface on the control unit. This enables time-division switching of communication and connection for each device to be charged, ensuring that the pigeon tracker can be used in a fully charged and normal state, and avoiding racing accidents caused by insufficient power or equipment failure of the pigeon tracker.

[0105] In one possible implementation, the dual-channel module switches are connected to each other and to the charging unit via a UART serial port.

[0106] Optionally, the dual-channel module switches are connected to each other and to the charging interface of the charging unit via a UART serial port, which has many advantages such as simplicity, flexibility, wide support, long-distance communication capability, easy debugging, multi-machine communication capability and low cost.
