[0023] Reference Figure 1An electromagnetic battery swapping lock mechanism includes an electromagnetic lock body, a latch, a control system, and sensors. All parts work together to provide a reliable guarantee for efficient battery swapping of new energy vehicles.

[0024] I. Electromagnetic lock body

[0025] The electromagnetic lock body is installed on the battery swapping equipment and is a key component for achieving battery swapping locking and unlocking.

[0026] Electromagnetic coil:

[0027] The electromagnetic coil is meticulously wound from high-quality conductive material, with its number of turns and wire diameter precisely calculated and optimized. The selection of the number of turns ensures the generation of a sufficiently strong magnetic field to meet the attraction requirements of the latch under different operating conditions. The determination of the wire diameter takes into account both current carrying capacity and heat dissipation performance, ensuring that the electromagnetic coil will not be damaged by overheating during operation.

[0028] The electromagnetic coil winding process employs advanced automated equipment to ensure the coil's uniformity and stability. Each turn of wire is tightly packed, reducing gaps and magnetic leakage, thereby improving the efficiency and strength of the magnetic field.

[0029] Iron core:

[0030] The core is made of a highly magnetically permeable material, such as high-quality silicon steel sheets. Silicon steel sheets have the characteristics of low hysteresis loss and high magnetic permeability, which can effectively enhance the magnetic field strength and improve the performance of the electromagnetic lock.

[0031] The shape of the iron core is carefully designed to optimize the distribution of the magnetic field. Common iron core shapes include "E" and "U" shapes, with different shapes suitable for different application scenarios. In this invention, the most suitable iron core shape was selected according to the specific requirements of the battery swapping equipment to ensure that the magnetic field can be concentrated in the locking area, thereby improving the reliability of locking.

[0032] The surface of the iron core undergoes special treatment, such as coating with insulating varnish, to prevent short circuits and eddy current losses between the cores. This treatment also improves the corrosion resistance and wear resistance of the iron core, extending its service life.

[0033] Power module:

[0034] The power module provides a stable and reliable power supply to the electromagnetic coil. It can be a DC or AC power supply, depending on the design requirements and application scenario of the electromagnetic lock.

[0035] The DC power supply module employs advanced voltage regulation technology to ensure output voltage stability. It also features overcurrent protection, overvoltage protection, and short-circuit protection to prevent damage to the electromagnetic lock body due to power supply failure.

[0036] The AC power module employs a high-efficiency transformer and rectifier circuit to convert AC power into DC power suitable for the operation of the electromagnetic coil. Simultaneously, it uses filters and other components to purify the power supply, reducing electromagnetic interference and improving system stability.

[0037] Control circuit:

[0038] The control circuit is the core part of the electromagnetic lock. It is responsible for controlling the current and switching time of the electromagnetic coil, thereby adjusting the magnetic field strength and locking time.

[0039] The control circuit employs advanced microprocessor and digital signal processing technology, enabling precise control of current magnitude and on / off time. Based on a preset program and sensor feedback, the microprocessor adjusts control parameters in real time to meet diverse battery swapping requirements.

[0040] To adjust the current magnitude, control circuits can employ various methods, such as variable resistors and PWM modulation. Variable resistors allow for manual or automatic adjustment of the resistance value, thereby changing the current magnitude. PWM modulation, on the other hand, controls the average current value by altering the pulse width; this method is highly efficient and precise, making it suitable for applications requiring strict current control.

[0041] In terms of controlling the on / off time, the control circuit can use timers, counters, etc. Timers can be set with different time parameters and automatically control the on / off state of the electromagnetic coil according to the preset time. Counters, on the other hand, can count the number of times the electromagnetic coil is switched on and off based on signals from sensors or other triggering conditions, thereby achieving precise control of the locking time.

[0042] II. Lock

[0043] The latch is installed on the battery compartment of new energy vehicles and works closely with the electromagnetic lock body to ensure safety and reliability during the battery swapping process.

[0044] Material selection:

[0045] The latch is made of high-strength materials, such as alloy steel and stainless steel. These materials are characterized by high hardness, high wear resistance, and high corrosion resistance, enabling them to withstand long-term use and harsh environmental conditions.

[0046] The surface of the latch undergoes special treatments, such as chrome plating or zinc plating, to improve its corrosion resistance and aesthetics. Additionally, an anti-slip design can be incorporated to increase friction between the latch and the electromagnetic lock body, enhancing locking reliability.

[0047] Structural design:

[0048] The latch's structural design has been carefully optimized to ensure a tight fit with the electromagnetic lock body. The latch's shape and size match the keyhole of the electromagnetic lock body, enabling precise locking and unlocking.

[0049] The latch's internal structure employs a special design, such as spring loading and ball locking, to increase the stability and reliability of the lock. Spring loading maintains a certain pressure on the latch in the locked state, preventing it from loosening due to vibration or external force. Ball locking provides additional resistance when locked, preventing the latch from being accidentally opened.

[0050] III. Control System

[0051] The control system is the brain of the electromagnetic lock mechanism. It is responsible for receiving signals, controlling the movement of the electromagnetic lock body, and monitoring the status of the electromagnetic lock body.

[0052] Signal reception:

[0053] The control system can receive signals from sensors, intelligent control systems, and other external devices. These signals include docking signals between the battery swapping equipment and the new energy vehicle, locking and unlocking commands, fault alarm signals, etc.

[0054] The control system employs advanced signal processing technology, capable of filtering, amplifying, and digitizing received signals to improve signal quality and reliability. Simultaneously, software algorithms can analyze and judge the signals to determine whether corresponding operations need to be performed.

[0055] Motion control:

[0056] The control system controls the movement of the electromagnetic lock body based on the received signals. When a locking command is received, the control system sends a locking signal to the electromagnetic lock body, energizing the electromagnetic coil to generate a magnetic field that attracts the latch and locks the lock. When an unlocking command is received, the control system cuts off the power to the electromagnetic coil, releasing the magnetic field and unlocking the latch.

[0057] The control system can also automatically perform locking and unlocking operations based on preset programs and information from sensor feedback. For example, after the battery swapping equipment is docked with the battery compartment of a new energy vehicle, the control system automatically detects the docking status. If the locking conditions are met, it automatically sends a locking signal to lock the device. When unlocking is required, the control system can automatically send an unlocking signal based on preset time, instructions, or other conditions to unlock the device.

[0058] Status monitoring:

[0059] The control system monitors the status of the electromagnetic lock body in real time through sensors, including locked, unlocked, and faulty states. The sensors transmit the detected information to the control system, which analyzes and processes this information to determine the current status of the electromagnetic lock body.

[0060] The control system can also monitor the operating parameters of the electromagnetic lock body, such as current, voltage, and magnetic field strength. These parameters reflect the working status and performance of the electromagnetic lock body. By monitoring and analyzing these parameters, potential problems can be identified in a timely manner, and corresponding measures can be taken to address them.

[0061] IV. Sensors

[0062] Sensors are used to detect the status of the lock mechanism and transmit the information to the control system, providing data support for the intelligent control of the electromagnetic battery-swapping lock mechanism.

[0063] Type selection:

[0064] The type of sensor is selected based on the specific detection requirements. Common sensors include position sensors, pressure sensors, current sensors, and voltage sensors.

[0065] Position sensors detect the relative position between the latch and the electromagnetic lock body, determining the locked and unlocked states. Pressure sensors detect the contact pressure between the latch and the electromagnetic lock body, ensuring reliable locking. Current and voltage sensors detect the operating current and voltage of the electromagnetic coil, providing feedback to the control system and enabling adjustments to the magnetic field strength and locking time.

[0066] Installation location:

[0067] The sensor mounting locations are carefully designed to ensure accurate detection of the locking mechanism's status. For example, position sensors can be installed at the contact points between the latch and the electromagnetic lock body, while pressure sensors can be installed inside the latch or around the keyhole of the electromagnetic lock body.

[0068] The installation method of the sensor should ensure its stability and reliability, avoiding factors such as vibration and impact that could affect the detection accuracy. At the same time, protective measures should also be considered to prevent damage to the sensor from external environmental influences.

[0069] V. Intelligent Control System

[0070] The intelligent control system is connected to the control system, providing the electromagnetic battery swapping lock mechanism with a higher level of intelligence and convenience.

[0071] CPU:

[0072] The central processing unit (CPU) is the core of an intelligent control system, responsible for processing various data and instructions. It employs a high-performance microprocessor, possessing rapid data processing capabilities and stable operating performance.

[0073] The central processing unit (CPU) can run complex algorithms and programs to achieve intelligent control of the electromagnetic battery swapping lock mechanism. For example, based on information from sensor feedback, it can automatically adjust the magnetic field strength and locking time to adapt to different battery swapping needs. It can also perform remote control and fault diagnosis functions.

[0074] Communication module:

[0075] The communication module is used to communicate with the electromagnetic lock body, sensors, and other systems in the battery swapping equipment. Wireless communication technologies such as Bluetooth, Wi-Fi, and ZigBee are employed to ensure stable and reliable data transmission.

[0076] The communication module enables connectivity with mobile apps and remote control devices, allowing users to send lock and unlock commands and monitor the lock mechanism's status in real time. Simultaneously, the communication module can also integrate with other systems within the battery swapping equipment to achieve collaborative operation, improving both the efficiency and security of the swapping process.

[0077] Display module:

[0078] The display module uses a screen to show the user the status information of the locking mechanism, such as locked, unlocked, or faulty status. The screen can be an LCD or OLED display, offering high definition and good visibility.

[0079] The display module can also show other relevant information, such as battery level and battery swapping progress, providing users with more comprehensive information services. Simultaneously, the display module can intuitively display the status of the lock mechanism through a graphical interface and indicator lights, facilitating user operation and use.

[0080] Storage module:

[0081] The storage module stores system settings, historical data, and other information. It uses flash memory and other storage media to ensure data security and reliability.

[0082] The storage module can store user-defined settings, such as lock time and magnetic field strength, allowing users to quickly access them in different usage scenarios. It can also store historical data, such as battery swap counts and fault records, providing data support for equipment maintenance and management.

[0083] VI. Working Principle and Process

[0084] After the battery swapping equipment is connected to the battery compartment of the new energy vehicle, the sensor detects the connection signal and transmits it to the intelligent control system.

[0085] The central processing unit of the intelligent control system determines whether the locking conditions are met according to a preset program. If they are met, a locking command is sent to the control system.

[0086] After receiving the locking command, the control system sends a locking signal to the electromagnetic lock body, which energizes the electromagnetic coil to generate a magnetic field, attracting the latch to achieve locking.

[0087] During the locking process, sensors monitor the status of the locking mechanism in real time and transmit the information to the control system and intelligent control system. Based on the sensor feedback, the control system adjusts the current and switching time of the electromagnetic coil to ensure reliable locking. The intelligent control system then displays the locking status and other relevant information to the user through a display module.

[0088] When unlocking is required, users can send unlock commands via a mobile app or other remote control devices. The remote control devices connect to the intelligent control system's communication module via a network, transmitting the commands to the central processing unit.

[0089] After receiving the unlock command, the central processing unit sends an unlock command to the control system. The control system then cuts off the power to the electromagnetic coil, releasing the magnetic field and unlocking the latch.

[0090] During the unlocking process, sensors monitor the lock mechanism's status in real time and transmit the information to the control system and intelligent control system. The control system ensures smooth unlocking based on the sensor feedback. The intelligent control system then displays the unlocking status and other relevant information to the user via a display module.

[0091] In summary, the electromagnetic battery swapping lock mechanism of the present invention has the advantages of reasonable structural design, stable and reliable performance, and high level of intelligence. It can effectively solve the problems existing in the current battery swapping lock mechanism, improve the efficiency and safety of battery swapping, and has broad market prospects and application value.
