A digital door lock assembly is provided to automatically open or close a sliding cover after the sliding cover is slid to a predetermined spot by elastic return force of a compression coil spring installed in a toggle spring mechanism. In a digital door lock assembly(10), a toggle spring mechanism(30) applies elastic force to a sliding cover(17) oppositely to the sliding direction until the sliding cover reaches a predetermined spot and applies the elastic force in the sliding direction from the position over the predetermined spot. The toggle spring mechanism is composed of a compression coil spring(31) of which one end is supported to a body(15) and the other end is supported to the sliding cover to maximize compressive deformation degree when the sliding cover is positioned at the predetermined spot; a support member(32) of which one end is rotatably combined to the sliding cover; and a rotating body(33) formed with an insertion hole into which the other end of the support member is slidably fitted, and rotatably combined to the body. The compression coil spring is fitted to the support member.
