Description

This disclosure relates to a non-retractable transmission device for motor output gears and an electronic lock for a vehicle charging socket. The electronic lock is a crucial component of the AC charging socket for electric vehicles. The electronic lock locks the charging gun while it is plugged in for vehicle charging and provides feedback to the vehicle that the charging gun is locked. The internal transmission structure of currently available electronic locks consists of a motor output gear that transmits power to an intermediate gear set, which in turn drives the intermediate gear set. The intermediate gear set transmits the motor's power to the locking rod rack, which in turn allows the locking rod rack to perform locking or unlocking actions. These three gear sets mesh with each other and drive the electronic lock to operate. However, in current electronic locks, the motor output gear rotates slightly in the reverse direction at the moment of power cut-off when extending or retracting the locking rod. This slight reverse rotation of the motor output gear drives the associated gears to rotate in the reverse direction, causing the locking rod to retract. This is a side view of a non-retractable transmission device connected to a motor output gear, according to one embodiment of the present disclosure.This is a cross-sectional view showing the connection of a non-retractable transmission device to a motor output gear in a cross-section along the rotational centerline, according to one embodiment of the present disclosure.This is a cross-sectional view showing the connection of a non-retractable transmission device to a motor output gear in a section perpendicular to the rotational centerline, according to the present disclosure.This is a side view showing the configuration of connecting a non-retractable transmission device to other components according to one embodiment of the present disclosure. While this disclosure is fully described with reference to the accompanying drawings, including preferred embodiments thereof, it will be understood prior to this description that those skilled in the art can modify the disclosure as described herein while still realizing the technical benefits of this disclosure. Therefore, it will be understood that the above description is intended to be a broad disclosure to those skilled in the art and is not intended to limit this disclosure to the exemplary embodiments described herein. The following detailed description includes numerous specific details to facilitate explanation and provide a complete understanding of the embodiments disclosed herein. However, it will become clear that one or more embodiments can be carried out without these specific details. In other examples, well-known structures and devices are shown schematically for the sake of simplifying the drawings. According to the general concept of this disclosure, a non-retractable transmission device for a motor output gear is provided, comprising a body and a support frame. The body comprises a motor engaging gear, which is configured to engage with the motor output gear to transmit power from the motor output gear, and after the teeth of the motor engaging gear engage with the teeth of the motor output gear, a buffer space configured for a preset stroke exists between the teeth of the motor engaging gear and the teeth of the motor output gear. The advantage of this disclosure is that the anti-retraction transmission device of this disclosure is coupled between the motor output gear and the transmission gear, and there is an engagement gap or backlash between the engaged teeth of the motor output gear and the anti-retraction transmission device to buffer slight reverse rotation of the motor output gear. Therefore, even if the motor gear reverses at the moment the power to the electronic lock is cut off, the locking rod of the electronic lock will not be retracted.
