Double-gear drive mechanism and double-gear drive device

Abstract

The invention provides a double-gear drive mechanism and a double-gear drive device, which relate to the field of air conditioner equipment. The double-gear drive mechanism comprises a drive motor, afirst gear, a second gear, a first connecting rod, a second connecting rod, a slip limiting piece and a blocking piece. The drive motor is connected with the first gear; the first gear is connected with the second gear through the slip limiting piece; the blocking piece and the second connecting rod are arranged at an interval; the blocking piece is used for selectively pressing against the secondconnecting rod; and the first gear is used for rotating relative to the second gear when the blocking piece presses against the second connecting rod. Compared with the prior art, according to the double-gear drive mechanism provided by the invention, the first gear meshed with a first rack part and the second gear meshed with a second rack are adopted, so that the drive motor can simultaneouslydrives the first connecting rod and the second connecting rod to form different movement loci, the first connecting rod and the second connecting rod accomplish specific mechanical driving, and the double-gear drive mechanism is reliable to move, less in parts, practical and high-efficient.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a double-gear drive mechanism and a double-gear drive device. Background technique [0002] Split wall-mounted air conditioners are usually equipped with a wind deflector structure, which can rotate around a certain axis to guide the direction of the wind. In the cooling mode, the air deflector rotates to an angle parallel to the ground to guide the cold air to the upper part of the room; while in the heating mode, the air deflector rotates to the vertical direction as much as possible to guide the hot air to the ground , to improve the comfort of the air conditioner. [0003] However, some of the existing air deflector mechanisms have a fixed axis of the air deflector, and the range of the air deflector angle is limited, which cannot meet the requirements of air deflector during cooling or heating at the same time; The rotation axis of the plate is movable, which can meet the a...

[0003] However, some of the existing air deflector mechanisms have a fixed axis of the air deflector, and the range of the air deflector angle is limited, which cannot meet the requirements of air deflector during cooling or heating at the same time; The rotation axis of the plate is movable, which can meet the air guide requirements of cooling or heating at the same time, but its structure is complex, and generally requires at least 3 motors to drive; and if these two problems are to be solved at the same time, higher production costs and complex manufacturing process
