Wherein the guard gear 22 is used to prevent damage to the motor 30 and/or damage to the teeth of the rack 41 and the power gear 21. When a panel of a typical air conditioner is subjected to a large resistance during movement, such as human resistance, sundries resistance, etc., the panel is blocked from movement by an external force, and the rack 41 connected to the panel is also blocked from the force, at this time, if the motor 30 is still outputting (rotating), and the gear portion 20 and the rack 41 are in a stress concentration state, the teeth of the gear portion 20 and the rack 41 may be damaged, causing wear of the teeth, and possibly causing damage to the motor 30. Therefore, by providing the guard gear 22, it is possible to protect the motor 30, and/or the teeth of the rack 41 and the power gear 21, when the rack 41 is subjected to resistance.
Referring to fig. 5-6, fig. 5 is an exploded view of the shield gear of the present invention, and fig. 6 is a cross-sectional view of the shield gear of the present invention. Specifically, in the present embodiment, the protection gear 22 includes a connection shaft 221, a stopper 222, a driving gear 223, a driven gear 224, and a spring 225. Two ends of the connecting shaft 221 are respectively provided with a limit portion 2211 and a limit groove 2212, the connecting shaft 221 sequentially penetrates through the driven gear 224 and the driving gear 223, and the limit portion 2211 is abutted to the lower side of the driven gear; the limiting member 222 is clamped into the limiting groove 2212 and is abutted against the upper side of the driving gear 223, the limiting portion 2211 and the limiting member 222 achieve a limiting effect, the driven gear 224 and the driving gear 223 are limited between the limiting portion 2211 and the limiting groove 2212 of the connecting shaft 221, the limiting portion 2211 can be an annular protrusion protruding outwards from the lower end edge of the connecting shaft 221, the limiting groove 2212 can be an annular groove, and the limiting gasket can be a clamp spring clamped in the annular groove. The connecting shaft 221 has a hollow structure so that the protection gear 22 is installed in the mounting box 10 through the rotating shaft.

In this embodiment, the spring 225 is held in a 30% -40% compressed state. The driving gear 223 is engaged with the power gear 21, and the driven gear 224 is engaged with the rack 41.
Since the spring 225 is compressed, the spring 225 generates a spring force, and both ends of the spring 225 generate a pressure N against the driving gear 223 and the driven gear 224, and according to a friction formula, a friction force F ═ μ N exists between the end surface of the spring 225 and the gear end surface, between the driving gear 223 and the stopper 222, and between the driven gear 224 and the stopper portion 2211. Under normal conditions, when the power gear 21 rotates, the driving gear 223 is driven to rotate, the driving gear 223 drives the driven gear 224 to rotate through friction, and the driven gear 224 drives the rack 41 to move. When the force applied to the rack 41 is greater than F, the force applied to the driven gear 224 is also greater than F, and the power gear 21 rotates to drive the driving gear 223 to rotate, because the resistance applied to the driven gear 224 is greater than F, the driving gear 223 cannot continue to drive the driven gear 224 to rotate through friction, and a slip occurs between the driving gear 223 and the spring 225 as well as between the driving gear 223 and the limiting member 222. It can be understood that, with this arrangement, when the rack 41 is subjected to a large resistance, a slip phenomenon occurs in the protection gear 22, and both the motor 30 and the teeth of the rack 41 and the power gear 21 can be protected.
