Abstract

This invention discloses an electrically operated hood lock, characterized by comprising: a housing assembly including a housing and a mounting plate fixed to each other; a lock block assembly including a ratchet and a pawl rotatably mounted on the housing assembly, and an elastic element providing a restoring force for the ratchet and pawl; a latching and opening mechanism including a slider reciprocally slidably mounted on the housing assembly, and a cam mounted on the slider; and a drive assembly including a latching cable and an opening cable electrically connected to a door lock controller; wherein both the latching cable and the opening cable are connected to the slider, and the bidirectional sliding of the slider on the housing assembly drives the ratchet or pawl to move, thereby realizing the electrically latching and opening functions of the hood. This design integrates the two core functions of electrically latching and opening through the bidirectional movement of a single slider, resulting in a highly simplified structure.
