Sliding or rotating mechanism of mechanical locking device
In the design of DC charging piles and electric vehicle (EV) charging interfaces, the sliding or rotating mechanism is a key component to ensure the stability, convenience and safety of charging connections. These mechanisms involve the physical interaction between the charging gun and the electric vehicle interface, enabling efficient connection and disconnection.
Main component
concept
Sliding mechanism: Linear sliding operation is adopted between the charging gun and the electric vehicle interface, making the insertion and removal process smoother. This design is usually used in scenarios where the connector type is relatively simple.
Rotation mechanism: The charging gun and the interface are connected by rotation, and the connection is closed or opened by rotation, which increases the firmness and stability of the connection.
Working Principle
Sliding mechanism
Insertion process: When the user inserts the charging gun into the charging port of the electric vehicle, the conductive slider (or conductive contact) between the gun body and the interface is physically connected by sliding in a straight line.
Release process: The user directly pulls the charging gun, and the conductive parts slide relative to each other to realize the disconnection without damage to the physical connection.
Rotating mechanism
Insertion process: After the user inserts the charging gun into the charging port of the electric vehicle, the pin or clasp inside the connector is stuck into the fixed position of the interface by rotating the handle of the charging gun or a specific rotating device, so as to realize the effective connection between the charging gun and the interface.
Release process: Apply a rotating force in the opposite direction to loosen the internal mechanism of the connector, so that the charging gun can be safely pulled out.
Design considerations
Mechanical strength
Whether it is a sliding or rotating mechanism, it needs to be designed to withstand mechanical stresses such as tension and torsion during charging to prevent loose connections or component damage.
Material selection
The right material selection is crucial for sliding or rotating mechanisms. Often stainless steel, reinforced plastics and other wear-resistant materials are used to ensure the durability and long-term stability of the joints.
Ease of operation
The design needs to consider the user experience and ensure that the plugging and unplugging process is simple and convenient, perhaps adding an indicator light or sound feedback to confirm that the connection is successful.
Summary
The sliding or rotating mechanism plays an important function and safety role in the design of DC charging pile. With the continuous development of electric vehicle technology, the innovation and improvement of these connection mechanisms will directly affect the charging efficiency and user experience. In future designs and improvements, manufacturers need to balance safety, user friendliness and cost to drive advances in EV charging infrastructure.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
