Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, and more particularly to a lithium battery for remote control unlocking. Background Technology

[0002] With the rapid development of lithium batteries, especially existing lithium battery technologies, there are already electronic lock products that can be remotely controlled via Bluetooth or Wi-Fi. Users can send commands via a mobile app, which are received by a wireless module and then driven by a control unit to complete the unlocking action, replacing traditional mechanical keys and improving convenience.

[0003] However, existing technologies have the following drawbacks or shortcomings:

[0004] 1. Limited communication coverage: Bluetooth and Wi-Fi have short communication distances, making them unsuitable for wide area network remote control and outdoor or long-distance scenarios.

[0005] 2. Lack of remote status monitoring: After the user sends the unlock command, it is impossible to know in real time whether the lock has actually unlocked or locked, and the operation result is not transparent.

[0006] 3. Lack of lithium battery management: The battery status cannot be remotely monitored, which can easily lead to lock failure due to battery depletion; at the same time, the lack of protection mechanisms means that long-term overcharging or over-discharging of lithium batteries will shorten their lifespan and pose safety hazards.

[0007] 4. Insufficient security: Some products lack command encryption and authentication mechanisms, posing a risk of being illegally remotely controlled.

[0008] 5. No anti-tamper alarm: When the lock is illegally removed, it cannot send an alarm to the user, and the safety of property cannot be guaranteed.

[0009] Therefore, existing technologies cannot meet the comprehensive needs for remote status monitoring, battery safety protection, and wide-area communication. Summary of the Invention

[0010] This invention provides a lithium battery for remotely controlling unlocking. It achieves wide-area remote communication via a 4G module, verifies specific instructions to ensure security, a motor drives an actuator to complete mechanical actions, a lock status and battery status detection unit collects data, the 4G module transmits data back for remote monitoring, and a photosensitive optocoupler provides physical tamper protection. These modules work collaboratively to solve the problems of insufficient remote monitoring, lack of battery management, and low security in existing technologies.

[0011] To address the aforementioned issues, this invention provides a lithium battery for remotely controlling unlocking, comprising a lithium battery, a 4G communication module, a power module, a PCB circuit board, and an electronic lock. The lithium battery is connected to the PCB circuit board, which includes a control unit (MCU), GPS, a photosensitive optocoupler anti-tamper unit, a battery status detection unit, and a power management unit. The electronic lock includes an electronic lock control board, a push-pull electric actuator, and a lock status detection unit.

[0012] The power module provides power to the system;

[0013] The 4G communication module: accesses the mobile network to achieve bidirectional data transmission with the mobile app and cloud server;

[0014] The control unit (MCU) receives instructions from the 4G communication module and performs decryption and verification of specific instruction codes.

[0015] The photosensitive optocoupler anti-tamper unit: When the lithium battery is illegally removed, causing light to enter, the state of the photosensitive optocoupler changes, triggering an anti-tamper signal to be sent to the control unit MCU;

[0016] The electronic lock control board is equipped with a motor drive circuit and receives the level signal output by the control unit MCU to drive the motor and the push-pull electric actuator to complete mechanical actions.

[0017] A further embodiment is that, driven by a motor, the push-pull electric actuator causes the push-pull rod of the electronic lock to perform a linear push-pull motion.

[0018] A further embodiment involves the push-pull rod acting directly on the bolt via a control signal line to achieve locking or unlocking.

[0019] A further embodiment is that the integrated control chip of the lock state detection unit is equipped with a Hall sensor to detect the position of the bolt in real time, generate an "unlocked" or "locked" state signal, and feed it back to the control unit MCU.

[0020] A further proposed solution is that the battery status detection unit collects the voltage, current, and temperature of the lithium battery in real time, determines the remaining power, and sends the data to the control unit MCU.

[0021] A further solution is that the power management unit uses a buck circuit to provide stable power to each module and supports a low-power sleep mode controlled by the control unit MCU.

[0022] A further embodiment is that the photosensitive photocoupler device of the photosensitive photocoupler block anti-tamper unit is installed in a key position inside the lithium battery casing. When the state of the photosensitive photocoupler on the PCB circuit board changes, an anti-tamper signal is triggered and sent to the MCU.

[0023] A further solution is that the lithium battery is equipped with a security authentication mechanism. When the App and the electronic lock use encrypted communication (such as AES), and the unlocking or locking command must contain a specific instruction code, the control unit MCU will only respond to the legitimate command to prevent illegal operation.

[0024] A further embodiment involves connecting the PCB circuit board to a charging / discharging interface.

[0025] The beneficial effects of this invention are as follows: It includes a lithium battery, a 4G communication module, a control unit (MCU), a GPS, a PCB circuit board, a photosensitive optocoupler anti-tamper unit, a push-pull electric actuator, a lock status detection unit, a battery status detection unit, and a power management unit. The 4G module enables wide-area remote communication; the MCU verifies specific instructions to ensure security; the motor drives the actuator to complete mechanical actions; the lock status and battery status detection units collect data; the 4G module transmits data back for remote monitoring; and the photosensitive optocoupler provides physical anti-tamper protection. These modules work collaboratively to solve the problems of insufficient remote monitoring, lack of battery management, and low security in existing technologies. Attached Figure Description

[0042] Furthermore, the push-pull rod 3 acts directly on the bolt 2 via the control signal line 4 to achieve unlocking or locking.

[0043] Furthermore, the integrated control chip of the lock status detection unit is equipped with a Hall sensor to detect the position of the bolt 2 in real time, generate an "unlocked" or "locked" status signal, and feed it back to the control unit MCU.

[0044] Furthermore, the battery status detection unit collects the voltage, current and temperature of the lithium battery 7 in real time, determines the remaining power, and sends the data to the control unit MCU.

[0045] Furthermore, the power management unit uses a buck circuit to provide stable power to each module and supports a low-power sleep mode controlled by the control unit MCU.

[0046] Furthermore, the photosensitive optocoupler 6 device of the photosensitive optocoupler 6 anti-tamper unit 10 is installed in a key position inside the casing of the lithium battery 7.

[0050] This invention provides a lithium battery 7 for 4G remote control unlocking, comprising:

[0051] 1. Lithium battery 7 power module: Provides operating power for the entire system.

When the lithium battery 7 is illegally removed, causing light to enter, the state of the photosensitive optocoupler 6 changes, triggering an anti-tamper signal to be sent to the MCU.

[0060] 10. Security authentication mechanism: The App and the lock use encrypted communication (such as AES), and the unlocking / locking commands must contain specific command codes. The MCU only responds to legal commands to prevent illegal operations.

[0061] The differences between this invention and the prior art are as follows:

[0068] 1. This invention enables remote real-time monitoring: managers can view the lock's open / closed status at any time via an app, and the operation results are transparent and controllable, greatly improving management efficiency.
