Description

Technical Field

[0001] The utility model relates to the technical field of electronic locks, and in particular to an electronic lock for a charging socket. Background Art

[0002] Electronic locks are advanced security devices that precisely control mechanical switches by inputting a password to control the operation of a circuit or chip, unlocking or locking the door. These locks are widely used in residential areas such as hotels, guesthouses, apartments, and villas, and offer significant security advantages, such as anti-theft alarms, effectively overcoming the limitations of traditional mechanical combination locks, such as their limited number of passwords and low security.

[0003] With technological advancements and expanding application scenarios, the use of electronic locks has expanded to new energy vehicle charging facilities. To enhance the safety of new energy vehicles during AC charging, all charging sockets with AC charging currents greater than 16A must be equipped with electronic locks. These specialized charging socket electronic locks not only feature electrically driven locking and opening functions, but also signal feedback and an emergency mechanical release feature, ensuring safe and convenient use in a variety of situations.

[0004] However, the common manual unlocking mechanism on the market mainly uses a pull cord to drive the lock pin to achieve unlocking. This design is particularly inconvenient to operate on a charging socket with a small space. When the operator needs to hold the pull cord and pull it backward in a direction perpendicular to the movement of the lock rod, the operation is often very difficult due to the limitation of the installation position. If the operator tries to pull the cord from the plug-in direction parallel to the lock rod, the pull cord is likely to bend inside the shell. Since there is usually a sealing structure between the pull cord and the shell, the friction is relatively large, which not only makes the pulling action more difficult, but may also cause the pull cord to wear or even break, which undoubtedly increases the complexity of the operation and safety hazards.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Summary of the Invention

[0006] In response to the problems in the related art, the present invention proposes an electronic lock for a charging socket to overcome the above technical problems existing in the existing related art.

[0009] Furthermore, to provide a certain degree of protection for the decelerated DC motor, a matching protective shell is provided on the outside of the decelerated DC motor, and the protective shell is connected to the housing via bolts. To facilitate the reset effect of the unlocking rack, a spring is sheathed on the outside of one end of the unlocking rack, and the other end of the spring is connected to the inner wall of the housing.

[0010] Furthermore, to facilitate the user's ability to pull the pull cord in any direction, better adapt to the installation of the socket electronic lock in a confined space, and meet the installation requirements of the socket electronic lock, the steering mechanism includes a mounting base, with a connecting tube interspersed in the middle of the mounting base. A sphere is provided at one end of the connecting tube, the interior of the sphere is provided with a cavity, and pulleys are provided on one side of the inner top and bottom of the cavity. A sliding block is provided on one side of the sphere, and one end of the pull cord passes through the connecting tube, two sets of pulleys, and the sliding block in sequence and extends to the outside of the housing.

[0011] The beneficial effects of the utility model are:

[0012] 1) By providing components such as a reduction DC motor, a gear transmission structure, and a mechanical unlocking structure, not only can the electric drive opening and closing function be realized under the action of the reduction DC motor and the gear transmission structure, but also the emergency unlocking function can be realized under the action of the mechanical unlocking structure.
