Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to an intelligent battery recycling device. Background Technology

[0002] Batteries, as portable energy supply devices, have become deeply integrated into all aspects of modern daily life. From small household appliances such as remote controls and electronic clocks to entertainment and outdoor products such as toy cars and radios, all rely on batteries for power. Their convenience makes them an indispensable core component of various portable electronic devices, widely covering diverse scenarios such as home, entertainment, communication, and outdoor activities.

[0003] However, in the daily use and disposal of batteries, users often cannot effectively distinguish between completely depleted batteries and those with residual power due to multiple batteries that look similar. They often mistakenly discard batteries that still have value as waste batteries based on subjective judgments (such as appearance and usage time). For batteries that cannot power high-power devices (such as toy cars) due to insufficient power, users often directly replace them with new batteries, ignoring the fact that their residual power can still meet the needs of low-power devices such as remote controls and electronic clocks, resulting in a large amount of residual power not being effectively utilized.

[0004] In addition, traditional battery disposal methods lack a dedicated mechanism for recovering residual power, which not only causes unnecessary loss of electrical energy resources, but also increases the frequency of battery replacement and usage costs, while exacerbating the pressure of disposing of used batteries and making it difficult to recover and reuse residual power.

[0005] Therefore, this application provides a smart battery recycling device to meet the demand. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an intelligent battery recycling device that can recycle and reuse the electricity of waste batteries, thereby avoiding energy waste.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A smart battery recycling device includes a housing, inside which a first mounting plate and a second mounting plate are installed, and a power recycling mechanism is disposed between the first mounting plate and the second mounting plate.

[0009] The power recovery mechanism includes a lower PCB board mounted on top of a second mounting plate, an upper PCB board mounted above the lower PCB board, and the upper and lower PCB boards electrically connected by wires to form a power recovery circuit. Both the upper and lower PCB boards integrate power detection chips and cooperate to recover residual battery power. The upper PCB board has multiple conductive pillars arranged in a circular array, with pressure rods slidably connected inside each conductive pillar. A pressure plate is fixed to the bottom end of each pressure rod. A battery storage tray is rotatably connected to the top of the lower PCB board. A stepper motor is mounted at the bottom of the second mounting plate, and the output end of the stepper motor passes through the second mounting plate and the lower PCB board and connects to the battery storage tray. A drive unit for driving the upper PCB board to move up and down is mounted on the side of the first mounting plate.

[0010] The top of the box is provided with a battery placement slot, and a battery guide post is installed at the bottom of the battery placement slot. The battery guide post is fixed inside the box by a connecting block, and the bottom end of the battery guide post is perpendicular to the battery storage tray.

[0011] The top of the housing is equipped with a discharge port and a control switch. The discharge port is electrically connected to the power recovery circuit of the power recovery mechanism and is used to output the recovered residual battery power.

[0012] Optionally, the driving unit is a telescopic electromagnet, which is mounted on the side of the first mounting plate via a bracket, and the output end of the telescopic electromagnet is connected to the upper PCB board to drive the upper PCB board to move in a direction perpendicular to the lower PCB board, so that the power recovery circuit formed by the PCB board and the lower PCB board, together with the power detection chip, realizes power detection and residual power recovery.

[0013] When a battery is inserted, the telescopic electromagnet is energized, its output end extends, driving the upper PCB board to move downwards. This brings the pressure plate on the conductive post into contact with the battery electrodes, initiating power detection and retrieval. After retrieval is complete, the electromagnet is de-energized, and the output end retracts, resetting the upper PCB board. Utilizing a telescopic electromagnet to move the upper PCB board vertically ensures stable and timely contact between the battery electrodes and the conductive post, guaranteeing smooth power detection and retrieval. Furthermore, the design is simple, responsive, and easy to control.

[0014] Optionally, the battery storage tray includes a rotating disk connected to the output end of a stepper motor. Multiple connecting plates are fixed in a circular array on the outer side of the rotating disk. Battery storage columns are fixed to the ends of the multiple connecting plates. The pressure plate of the pressure rod is located directly above the battery storage column. The pressure plate is used to press the battery tightly inside the battery storage column to ensure stable contact between the battery electrodes, so as to connect to the power recovery circuit of the upper PCB board and the lower PCB board to complete the recovery of residual power.

[0015] As the upper PCB moves downward, the pressure plate presses the battery firmly into the battery storage column, ensuring that the positive and negative terminals of the battery contact the contacts on the upper and lower PCBs respectively, thus connecting to the energy recovery circuit. The battery storage column positions the battery, and the pressure plate's action ensures stable contact between the battery electrodes and the circuit contacts, providing a reliable circuit connection for energy recovery. Furthermore, the design with multiple battery storage columns allows for continuous processing of multiple batteries, improving recovery efficiency.

[0016] Optionally, a discharge port is provided on the lower PCB board. The position of the discharge port is adapted to the movement trajectory of the battery storage column. A discharge plate is rotatably connected inside the discharge port. A servo motor is installed at the bottom of the lower PCB board. The output end of the servo motor is connected to the discharge plate through a transmission shaft to drive the discharge plate to rotate around the discharge port, thereby opening or closing the discharge port. This is used to classify and discharge batteries according to the residual battery power recovery status detected by the power detection chip.

[0017] Once battery recycling is complete, a stepper motor rotates the battery storage tray to align the target battery storage column with the discharge port. A servo motor then drives the discharge plate to open, allowing the batteries to fall to the bottom of the container under gravity. The discharge plate then closes. This system achieves automatic sorting and discharge of recycled batteries, processing them based on their remaining charge level. This facilitates subsequent sorting, collection, and processing, demonstrating a high degree of automation, reducing manual operation, and improving the device's practicality.

[0018] Optionally, a bracket is fixed to the bottom of the battery guide post, and an infrared sensor is installed on the bracket. The detection direction of the infrared sensor is towards the inside of the battery storage post, which is used to identify whether there is a battery inside the battery storage post, so as to trigger the power recovery circuit of the upper PCB board and the lower PCB board to start the residual power recovery process.

[0019] An infrared sensor is mounted on a bracket at the bottom of the battery guide post, with its detection probe pointing towards the inside of the battery storage post. When a battery falls into the storage post, it blocks the infrared light, and the sensor outputs a signal to the main control board, triggering a stepper motor to rotate and the upper PCB board to move downward, initiating the power recovery process. This achieves automatic detection and process initiation after battery placement, requiring no manual intervention, improving the automation and intelligence level of the device, and ensuring the timely start of the recovery process.

[0020] Optionally, a solar panel is also installed on the top of the enclosure. The enclosure contains a smoke sensor, a main control board, a relay, a power display module, and a display. The solar panel is electrically connected to the energy storage component inside the enclosure to power the device and the power recovery circuits of the upper and lower PCB boards. The infrared sensor, smoke sensor, stepper motor, telescopic electromagnet, servo motor, power display module, display, control switch, and power detection chip are all electrically connected to the main control board. The main control board receives the detection data from the power detection chip and the recovery information from the power recovery circuit and controls the actions of each actuator. The main control board is connected to each actuator via relays.

[0021] The solar panels are connected to the energy storage components inside the enclosure via a charge / discharge management module, providing power to the device. Components inside the enclosure, such as smoke sensors, the main control board, and relays, are connected to the main control board. The main control board receives signals from each component and controls the actions of these components via relays, achieving coordinated operation of the entire device. Utilizing solar power saves traditional energy and is more environmentally friendly; the collaborative work of all components through the main control board enables intelligent control and safety monitoring of the device, improving its reliability and safety.

[0022] Optionally, a limiting plate is fixed to the top of the pressure rod, the diameter of which is larger than the inner diameter of the conductive column, to limit the sliding stroke of the pressure rod within the conductive column.

[0023] The limiting plate at the top of the pressure rod has a diameter larger than the inner diameter of the conductive post. When the upper PCB board moves downward, the pressure rod moves downward accordingly. After the pressure plate contacts the battery, the pressure rod slides upward relative to the conductive post. When the upper PCB board moves upward, the limiting plate contacts the top of the conductive post, stopping the pressure rod from moving. This effectively limits the sliding stroke of the pressure rod, avoiding battery damage caused by excessive pressure, and ensures synchronous reset of the pressure rod when the upper PCB board resets, ensuring the accuracy of subsequent battery processing.

[0024] Optionally, a water storage basin is also provided on the top of the housing. A water pump is installed inside the water storage basin, and a drain outlet is provided on the water storage basin. The drain outlet is connected to the housing through a pipe and is used to extinguish the fire when the smoke sensor detects an abnormality, and to protect the power recovery circuit and other circuit components of the upper PCB board and lower PCB board.

[0025] The water pump inside the water storage basin is connected to the interior of the enclosure via a hose. When the smoke sensor detects that the smoke concentration exceeds the threshold, the main control board cuts off the power and starts the water pump, spraying water into the enclosure. In case of fire or other abnormal situations, it can extinguish the fire in time, protecting the PCB circuitry and other electronic components, thus improving safety and service life.

[0026] Optionally, the display is electrically connected to the main control board and is used to receive user input instructions for setting power recovery parameters, and to display the battery recovery status, the power data detected by the power detection chip, and the residual power recovery information of the power recovery circuits on the upper and lower PCB boards.

[0027] The display connects to the main control board, allowing users to set parameters via a touch interface. The display shows real-time data such as recovery progress, battery voltage, recovered power, and any abnormal information. This visualizes the operation, enabling users to intuitively understand the equipment's operating status, facilitating parameter setting and troubleshooting, and improving the user experience and ease of use of the device.

[0028] Optionally, a limiting rod is also installed inside the housing, and the limiting rod is located below the upper PCB board to limit the movement of the upper PCB board during its downward movement, preventing the upper PCB board from moving too far downward and damaging the battery or affecting the accuracy of power detection.

[0029] The limiting rod inside the housing is located below the upper PCB board. When the upper PCB board moves downward, its bottom contacts the top of the limiting rod first, thus stopping its movement. This limits the downward movement distance of the upper PCB board, ensuring that the contact pressure between the conductive post and the battery electrode is moderate. This avoids damage to the battery or affect the accuracy of power detection caused by excessive downward movement, thus guaranteeing the stability of the device operation and the accuracy of detection.

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] The upper and lower PCB boards are connected by wires to form a power recovery circuit, and both integrate power detection chips to collaboratively detect battery power and recover residual power. Conductive posts, pressure rods, and pressure plates work together to contact the battery electrodes. The battery storage tray rotates under the drive of a stepper motor to transfer the batteries. The drive unit moves the upper PCB board up and down, controlling contact and separation. The battery enters the battery storage tray through the battery insertion slot and battery guide posts. The recovered power is output through the discharge port, constructing a complete intelligent battery recycling system. This system achieves automatic battery insertion, power detection, residual power recovery, and output, solving the problem of difficult utilization of residual power in traditional battery use and improving battery energy utilization efficiency.

[0052] This embodiment discloses an intelligent battery recycling device, which aims to solve the problem of difficulty in identifying and recycling residual battery power in the prior art, and to achieve efficient recycling and classification of residual battery power.

[0053] Embodiments of the present invention provide a smart battery recycling device, such as... Figure 1 As shown, the housing 1 has a first mounting plate 2 and a second mounting plate 3 mounted inside it with angle irons and bolts, which are parallel to each other and spaced 15-20cm apart. A power recovery mechanism 4 is located in the space between the first mounting plate 2 and the second mounting plate 3. Figure 1 and Figure 3 As shown, the power recovery mechanism 4 includes an upper PCB board 41 and a lower PCB board 42. The lower PCB board 42 is mounted on top of the second mounting plate 3. The surface of the lower PCB board 42 is printed with conductive lines and integrates a power detection chip (model INA219) for detecting battery voltage and current. The upper PCB board 41 is arranged parallel above the lower PCB board 42. The two are electrically connected by wires to form a closed power recovery loop. The upper PCB board 41 also integrates an auxiliary power detection chip, which works in conjunction with the chip on the lower PCB board 42. Five conductive pillars 411 are arranged in a circular array on the upper PCB board 41. Each of the five conductive pillars 411 is interconnected with the circuitry on the upper PCB board 41. A pressure rod 43 is slidably fitted inside each of the five conductive pillars 411. A pressure plate 432 is fixed to the bottom of each pressure rod 43. A battery storage tray 44 for storing batteries is rotatably connected to the top of the lower PCB board 42. The battery storage tray 44 can rotate around the central axis of the lower PCB board 42. A stepper motor 45 is mounted on the bottom of the second mounting plate 3. The output shaft of the stepper motor 45 passes through the second mounting plate and the lower PCB board and connects to the battery storage tray 44. A drive unit is fixed to the inner side of the second mounting plate 3 via a bracket. The drive end of the drive unit is connected to the center of the top of the upper PCB board 41, used to drive the upper PCB board 41 to move up and down. Figure 2As shown, a cone-shaped battery placement slot 6 is installed on the top of the housing 1. A hollow plastic battery guide post 61 is installed at the bottom of the battery placement slot 6. The battery guide post 61 is connected to the inner wall of the housing 1 through a connecting block 62. An opening is provided on the upper PCB board 41. The battery guide post 61 passes through the opening on the upper PCB board 41 and is vertically aligned with the battery storage tray 44. The top of the housing 1 is provided with a discharge port 8 (USB) and a control switch 9. The discharge port 8 is electrically connected to the power recovery circuit.

[0054] The mounting frame of the power recovery mechanism 4 is realized by setting a first mounting plate 2 and a second mounting plate 3 inside the housing 1. The upper PCB board 41 and the lower PCB board 42 are connected by wires to form a power recovery circuit, and both integrate power detection chips, which can work together to detect the battery power and recover residual power. The conductive post 411, the pressure rod 43 and the pressure plate 432 cooperate to contact the battery electrodes. The battery storage tray 44 can rotate under the drive of the stepper motor 45 to realize the transfer of batteries. The drive unit drives the upper PCB board 41 to move up and down, controlling the contact and separation. The battery enters the battery storage tray 44 through the battery placement slot 6 and the battery guide post 61. The recovered power is output through the discharge port 8, thus constructing a complete intelligent battery recycling system, realizing automatic battery placement, power detection, residual power recovery and output, solving the problem of the difficulty in utilizing residual power in traditional battery use, and improving the utilization rate of battery energy.

[0055] like Figure 1 and Figure 3 As shown, the driving unit is a telescopic electromagnet 46. The telescopic electromagnet 46 is installed on the inner side of the first mounting plate 2 via a bracket. The output end of the telescopic electromagnet 46 is connected to the top center of the upper PCB board 41. When the battery is inserted, the output end of the telescopic electromagnet 46 is energized and extends 5-10mm, driving the upper PCB board 41 to move downward in the vertical direction, so that the pressure plate 432 at the bottom of the pressure rod 43 inside the conductive post 411 contacts the top electrode of the battery. At this time, the power detection chip starts to detect and recover the power through the circuit. After the recovery is completed, the electromagnet is de-energized, and the output end of the telescopic electromagnet 46 retracts, driving the upper PCB board to reset.

[0056] The drive unit uses a telescopic electromagnet 46, with its output end connected to the upper PCB board 41. When a battery is inserted, the telescopic electromagnet 46 is energized, and its output end extends to drive the upper PCB board 41 to move downwards, causing the pressure plate 432 on the conductive post 411 to contact the battery electrode, thus initiating power detection and recovery. After recovery is complete, the electromagnet is de-energized, and its output end retracts, causing the upper PCB board 41 to reset. Utilizing the telescopic electromagnet 46 to move the upper PCB board 41 vertically ensures the stability and timeliness of contact between the battery electrode and the conductive post 411, guaranteeing the smooth operation of the power detection and recovery process. Furthermore, the structure is simple, the response is rapid, and the control is convenient.

[0057] like Figure 3 and Figure 4 As shown, the battery storage tray 44 includes a rotating disk 441. The center of the rotating disk 441 is connected to the output end of the stepper motor 45. Five connecting plates 442 are fixed in a circular array on the outer side of the rotating disk 441. Each of the five connecting plates 442 has a battery storage column 443 with a through bottom. The pressure plate 432 at the bottom of the pressure rod 43 is located above the battery storage column 443 and is used to press the battery into the battery storage column 443. When the upper PCB board 41 moves down, the pressure plate 432 at the bottom of the pressure rod 43 presses on the top of the battery in the battery storage column 443, pressing the battery to ensure that the positive and negative terminals of the battery are in contact with the contact point of the pressure plate 432 at the bottom of the pressure rod 43 in the conductive column 411 of the upper PCB board and the contact point of the lower PCB board, respectively, thereby connecting to the power recovery circuit.

[0058] The battery storage tray 44 consists of a rotating disk 441, a connecting plate 442, and battery storage columns 443. The rotating disk 441 is connected to the output terminal of the stepper motor 45. When the upper PCB board 41 moves downward, the pressure plate 432 presses the battery firmly into the battery storage column 443, so that the positive and negative terminals of the battery contact the contacts of the upper and lower PCB boards 42 respectively, connecting to the power recovery circuit. The battery storage column 443 positions the battery, and with the pressing action of the pressure plate 432, it ensures stable contact between the battery electrodes and the circuit contacts, providing a reliable circuit connection for power recovery. At the same time, the design of multiple battery storage columns 443 can realize the continuous processing of multiple batteries, improving the recovery efficiency.

[0059] like Figure 3 As shown, a discharge port is provided on the lower PCB board 42. The discharge port is located at the tangent position of the rotation trajectory of the battery storage column 443. A discharge plate 421 (with dimensions matching the discharge port) is connected to the discharge port through a pin. A servo motor 422 is mounted on the bottom of the lower PCB board 42 through a bracket. The output shaft of the servo motor 422 is connected to the discharge plate 421 through a transmission shaft. When the battery is recovered, the stepper motor 45 drives the battery storage tray 44 to rotate, so that the target battery storage column 443 is aligned with the discharge port. The main control board controls the servo motor 422 to rotate, and the discharge plate 421 flips down to open the discharge port. The battery falls into the bottom of the box 1 under the action of gravity. After discharge, the servo motor 422 rotates in the opposite direction to reset, and the discharge plate 421 closes the discharge port.

[0060] The discharge port on the lower PCB board 42 is adapted to the rotation trajectory of the battery storage column 443, and the discharge plate 421 is connected to the servo motor 422 via a drive shaft. After the battery is recycled, the stepper motor 45 drives the battery storage tray 44 to rotate so that the target battery storage column 443 is aligned with the discharge port. The servo motor 422 drives the discharge plate 421 to open, and the battery falls into the bottom of the box 1 under the action of gravity. Then the discharge plate 421 closes. This achieves automatic sorting and discharge of recycled batteries, processing them according to the residual charge recovery status, which facilitates subsequent sorting, collection and processing. It has a high degree of intelligence, reduces manual operation, and improves the practicality of the device.

[0061] like Figure 4 As shown, a bracket 611 is fixed to the bottom of the battery guide post 61. An E18-D80NK infrared sensor is fixed to the bracket 611 by bolts. The detection probe of the infrared sensor points towards the inside of the battery storage post 443 below. When the battery falls from the guide post 61 into the battery storage post 443, the infrared light emitted by the infrared sensor is blocked by the battery. The reflected signal triggers the sensor to output a high level to the main control board. After receiving the signal, the main control board starts the stepper motor 45 to drive the battery storage tray 44 to rotate, and triggers the upper PCB board 41 to move down to start the power recovery process, realizing unattended automated detection and start-up.

[0062] An infrared sensor is mounted on a bracket at the bottom of the battery guide post, with its detection probe pointing towards the inside of the battery storage post. When a battery falls into the storage post, it blocks the infrared light, and the sensor outputs a signal to the main control board, triggering a stepper motor to rotate and the upper PCB board to move downward, initiating the power recovery process. This achieves automatic detection and process initiation after battery placement, requiring no manual intervention, improving the automation and intelligence level of the device, and ensuring the timely start of the recovery process.

[0063] An infrared sensor is installed on the bracket 611 at the bottom of the battery guide post 61, with its detection probe pointing towards the inside of the battery storage post 443. When a battery falls into the battery storage post 443, it blocks the infrared light, and the sensor outputs a signal to the main control board, triggering the stepper motor 45 to rotate and the upper PCB board 41 to move downward, thus initiating the power recovery process. This achieves automatic detection and process initiation after battery insertion, requiring no manual intervention, improving the automation and intelligence level of the device, and ensuring the timely initiation of the recovery process.

[0064] like Figures 1-3 and Figures 7-11 As shown, a solar panel 10 is embedded in the top of the housing 1. The solar panel 10 is connected to the lithium battery (energy storage component) inside the housing through a charge and discharge management module to power the device.

[0065] The box also contains:

[0066] The MQ-2 smoke sensor is installed in the top corner of the enclosure.

[0067] The main control board and relays are installed at the top of the enclosure 1. The relays are connected to the main control board and control the power supply of each actuator.

[0068] Power display module 11, which consists of a 4-digit LED digital tube, is installed on the front of the box;

[0069] Display 12 is mounted on the side of power display module 11.

[0070] The connections between the components and the main control board are as follows: the infrared sensor, smoke sensor, voice playback module, stepper motor 45, telescopic electromagnet 46, servo motor 422, power display module 11, display 12, control switch 9, and power detection chip are all connected to the main control board's I / O port via wires. After receiving data from the power detection chip, the main control board controls the actions of the actuators via relays. The solar panel 10 provides clean energy for the entire system.

[0071] The solar panel 10 is connected to the energy storage component inside the housing 1 via a charge / discharge management module to power the device. Components inside the housing 1, such as the smoke sensor, main control board, and relays, are connected to the main control board. The main control board receives signals from each component and controls the actions of the components via relays, achieving coordinated operation of the entire device. Utilizing solar power saves traditional energy and is more environmentally friendly; the collaborative work of all components through the main control board enables intelligent control and safety monitoring of the device, improving its reliability and safety.

[0072] like Figure 3 As shown, a circular limiting plate 431 is welded to the top of the pressure rod 43. The diameter of the limiting plate 431 is larger than the inner diameter of the conductive post 411. When the upper PCB board 41 moves down, the pressure rod 43 moves down accordingly. After the pressure plate 432 contacts the battery, the pressure rod 43 slides upward relative to the conductive post 411. When the upper PCB board 41 moves up, the limiting plate 431 contacts the top of the conductive post 411, at which point the pressure rod 43 stops moving.

[0073] The diameter of the limiting plate 431 at the top of the pressure rod 43 is larger than the inner diameter of the conductive post 411. When the upper PCB board 41 moves downward, the pressure rod 43 moves downward accordingly. After the pressure plate 432 contacts the battery, the pressure rod 43 slides upward relative to the conductive post 411. When the upper PCB board 41 moves upward, the limiting plate 431 contacts the top of the conductive post 411, stopping the pressure rod 43 from moving. This effectively limits the sliding stroke of the pressure rod 43, avoiding battery damage caused by excessive pressure on the battery. At the same time, it ensures the synchronous reset of the pressure rod 43 when the upper PCB board 41 resets, ensuring the accuracy of subsequent battery processing.

[0074] like Figure 1 and Figure 2As shown, a plastic water reservoir 7 is located on the top left side of the enclosure 1. A DC3-6V miniature water pump 71 is installed inside the water reservoir 7. The drain outlet at the bottom of the water reservoir 7 is connected to the inside of the enclosure 1 via a flexible hose, with the hose opening facing the PCB board area. When the smoke sensor detects that the smoke concentration inside the enclosure exceeds 0.1 mg / m³... 3 In case of fire, the main control board immediately cuts off the power supply to the device and starts the water pump 71. The water in the water storage basin 7 is sprayed into the box through the hose to suppress the fire and protect the PCB circuit and electronic components.

[0075] The water pump 71 inside the water storage basin 7 is connected to the inside of the housing 1 via a hose. When the smoke sensor detects that the smoke concentration exceeds the threshold, the main control board cuts off the power and starts the water pump 71 to spray water into the housing 1. In case of fire or other abnormal situations, it can extinguish the fire in time, protect the PCB circuit and other electronic components, and improve safety and service life.

[0076] like Figure 1 and Figure 11 As shown, the display 12 is connected to the main control board via an interface, and its functions include:

[0077] Users can set the power recovery threshold (e.g., start recovery at 1.2V) through the touch interface;

[0078] Displays the current recycling progress in real time (e.g., "Recycling the 3rd battery");

[0079] The battery voltage (e.g., "1.35V") and reclaimed capacity (e.g., "85mAh") read by the power detection chip are displayed.

[0080] When the device malfunctions, it displays information such as "sensor failure";

[0081] The display 12 makes the operation visual, allowing users to intuitively grasp the operating status of the device.

[0082] The display 12 is connected to the main control board, allowing users to set parameters via a touch interface. The display 12 shows real-time data such as recovery progress, battery voltage, recovered power, and any abnormal information. This visualizes the operation, enabling users to intuitively understand the equipment's operating status, facilitating parameter setting and troubleshooting, and improving user experience and ease of use.

[0083] like Figure 1 and Figure 3 As shown, a rigid limiting rod 5 is fixed inside the housing 1, with the top of the limiting rod 5 3mm away from the initial position of the upper PCB board 41. When the upper PCB board 41 moves downward under the drive of the telescopic electromagnet 46, the bottom of the upper PCB board 41 contacts the top of the limiting rod 5 first, at which point the upper PCB board 41 stops moving, ensuring that the contact pressure between the conductive post 411 and the battery electrode is appropriate.

[0084] The limiting rod 5 inside the housing 1 is located below the upper PCB board 41. When the upper PCB board 41 moves downward, its bottom first contacts the top of the limiting rod 5, thus stopping its movement. This limits the downward movement distance of the upper PCB board 41, ensuring that the contact pressure between the conductive post 411 and the battery electrode is moderate. This avoids damage to the battery or affect the accuracy of power detection caused by excessive downward movement, thus ensuring the stability of the device operation and the accuracy of detection.

[0085] Working principle

[0086] like Figures 1-11 As shown, when the user places the battery into the cone-shaped battery slot 6 at the top of the housing 1, the battery falls along the hollow plastic battery guide post 61, passes through the opening on the upper PCB board 41, and finally falls into the battery storage post 443 of the battery storage tray 44. At this time, the infrared sensor installed on the bracket 611 at the bottom of the battery guide post 61 detects the battery. The infrared light emitted by the battery is blocked, and the reflected signal triggers the sensor to output a high level to the main control board.

[0087] After receiving the signal, the main control board starts the stepper motor 45 at the bottom of the second mounting plate 3. The output shaft of the stepper motor 45 drives the battery storage tray 44 to rotate, so that the battery storage column 443 containing the battery moves to the position corresponding to the conductive column 411 on the upper PCB board 41. At the same time, the next empty battery storage column 443 is aligned with the battery guide column 61 to receive the next battery.

[0088] Subsequently, the main control board energizes the telescopic electromagnet 46 inside the first mounting plate 2, causing its output end to extend 5-10mm, driving the upper PCB board 41 to move downwards vertically. When the upper PCB board 41 moves down to the bottom and contacts the limiting rod 5 inside the housing 1, it stops moving. At this time, the pressure plate 432 at the bottom of the pressure rod 43 inside the conductive post 411 contacts the top electrode of the battery, pressing the battery firmly inside the battery storage post 443. This ensures that the positive and negative terminals of the battery are in contact with the pressure plate 432 at the bottom of the pressure rod 43 inside the conductive post 411 in the upper PCB board 41 and the contact point of the lower PCB board 42, respectively, thus forming a closed power recovery circuit formed by the upper PCB board 41 and the lower PCB board 42 connected by wires.

[0089] The power detection chips integrated on the upper PCB board 41 and the lower PCB board 42 work together to detect the battery voltage and current. The detected power data is transmitted to the main control board. If the battery's remaining power reaches a set threshold (which can be set by the user through the touch interface of the display 12, such as 1.2V), the power recovery circuit is activated to recover the remaining power of the battery. The recovered power is stored in the lithium battery (energy storage component) inside the housing 1 or directly output through the discharge port 8. Information such as the recovery progress, battery voltage, and recovered power is displayed on the display 12 in real time.

[0090] During the power recovery process, when the upper PCB board 41 moves down, the pressure rod 43 moves down accordingly. After the pressure plate 432 contacts the battery, the pressure rod 43 slides upward relative to the conductive post 411. When the upper PCB board 41 moves up, the limiting plate 431 contacts the top of the conductive post 411, causing the pressure rod 43 to stop moving and preventing the pressure rod 43 from sliding excessively and affecting subsequent operations.

[0091] Once the residual battery power has been recovered, the main control board de-energizes the telescopic electromagnet 46, causing its output to retract and resetting the upper PCB board 41. Simultaneously, the main control board restarts the stepper motor 45, rotating the battery storage tray 44 so that the battery storage column 443 containing the recovered batteries aligns with the discharge port on the lower PCB board 42.

[0092] Next, the main control board controls the rotation of the servo motor 422 at the bottom of the PCB board 42. The output shaft of the servo motor 422 drives the discharge plate 421 to flip downwards via the transmission shaft, opening the discharge outlet. The battery falls into the bottom of the housing 1 under the action of gravity. After discharge is completed, the servo motor 422 rotates in the opposite direction to reset, and the discharge plate 421 closes the discharge outlet.

[0093] In addition, the solar panels embedded in the top of housing 1 power the entire device, including the main control board, various sensors, and actuators, through a charge / discharge management module. A smoke sensor inside housing 1 monitors the internal conditions in real time; when the smoke concentration exceeds 0.1 mg / m³, the sensor will detect the smoke. 3 In case of fire, the main control board immediately cuts off the power to the device and starts the water pump 71 in the water storage basin 7, spraying water into the box 1 through the hose to suppress the fire and protect the PCB circuit and other electronic components. The power display module 11 and the display 12 are used to display data such as the recovered power and equipment operating status information, so that users can intuitively understand the status of the device.
