Door lock motor assembly

Abstract

The invention relates to a door lock motor assembly, which includes: a frame including a linear guide groove; a motor installed on the frame, and the motor has an output shaft; a push rod with one end eccentrically and pivotably installed on the output wheel, and the middle position passes through The pin is mounted to the linear guide groove such that when the output wheel rotates about the output axis, the push rod translates along the linear guide groove relative to the frame while rotating about the pin axis; the hook includes a first part, a locking part and an arm connecting the first part and the locking part The first part is mounted to the linear guide groove through the same pin, so that the reciprocating motion of the pin along the linear guide groove also drives the hook to move relative to the frame, and the arm extends outward from the frame through the elongated opening slot defined by the frame; The elastic member biases the hook toward one end edge of the opening slot; wherein the push rod also includes a support member that overcomes the biasing force of the elastic member during the movement of the push rod and pushes the hook away from the one end edge, thereby Realize the locking and opening actions of the retractor.

Description

Technical field [0001] The present invention relates to a door lock motor assembly, in particular to a door lock motor assembly for an oven, and an oven adopting such a door lock motor assembly. Background technique [0002] The door lock motor assembly mainly includes a motor assembly used to lock the door after the oven door is closed. The working principle of the existing door lock motor is as disclosed in the patent document US7040674. The "opening" and "closing" of the door lock are realized by the cooperation of the two leading edges on the upper and lower sides of the hook with the corresponding upper and lower edges of the lock slot. [0003] In practice, this solution has the following shortcomings: the opening and closing action of the retractor is controlled by the cooperation of the two guiding edges of the retractor and the edge of the lock groove, and its movement accuracy is low, and the cooperation produces line friction and noise, which makes the material easy Wea...

Problems solved by technology

[0003] In practice, this solution has the following disadvantages: the opening and closing action of the draw hook is controlled by the cooperation between the two guide edges of the draw hook and the edge of the lock groove, the movement precision is low, and the cooperation produces line friction and noise, making the material easy to Wear and tear, resulting in higher costs; the travel path of the hook requires a lot of movement space
