By adopting the connecting rod assembly provided by the embodiment of the disclosure, the connecting rod component 10 is connected with the air deflector through the pushing part 101 so as to drive the air deflector to extend or retract; the rotating assembly 20 is arranged on the pushing part 101 to drive the air deflector to turn over; and the first gear 201 and the second gear 202 which are meshed with each other through the rotating component 20 enable the overturning angle of the air deflector to be more accurate in the overturning motion process of opening or closing the air outlet, and stability of the air deflector in the overturning motion process is also improved. The moving mechanism is simple in structure and is not prone to failure in the moving process of the air deflector.

The air deflector rotates relative to the pushing portion 101 under the driving of the rotating assembly 20, so as to perform an overturning motion, so as to open or close the air outlet of the air conditioner.

In the embodiment of the present application, the state of the air outlet of the air conditioner closed by the air deflector is set to be an initial state, and when the air outlet is opened by the air deflector, the air deflector is driven by the connecting rod member 10 to firstly perform an extending action, and then driven by the rotating assembly 20 to perform a turning action, so as to achieve the purpose of air outlet at the air outlet. When the air guiding plate extends for a set distance, the air guiding plate can extend and turn over under the action of the connecting rod member 10 and the rotating assembly 20. Therefore, on one hand, the time can be saved, and on the other hand, the air deflector is prevented from interfering with the shell of the air conditioner when being overturned.

Under the condition that the air deflector is to close the air outlet, the air deflector moves in three modes, namely, in the first mode, the air deflector can be driven by the connecting rod component 10 to retract, and then is driven by the rotating component 20 to turn over, so that the aim of closing the air outlet is fulfilled. In the second way, the air deflector can be driven by the rotating component 20 to perform a turning action, and then driven by the connecting rod component 10 to perform a retracting action to close the air outlet. In a third mode, the air deflector can rotate and retract simultaneously. Thus, the time from receiving the instruction to completely closing the air outlet can be saved.

In the embodiment of the present application, the driving assembly can drive the connecting rod member 10 to perform a linear motion, so that the connecting rod member 10 drives the air deflector to perform a linear motion, thereby achieving the purpose of opening or closing the air outlet by the air deflector. Wherein, in case of the link member 10 moving linearly, the air deflection plate and the rotation assembly 20 move in synchronization with the link member 10.

Through the meshing of first gear 201 and second gear 202, the number of teeth of second gear 202 is greater than the number of teeth of first gear 201, can carry out the speed reduction to the rotational speed of motor output to prevent that the aviation baffle rotates too fast.

Optionally, the thickness of the first gear 201 is the same as the thickness of the second gear 202. In this way, the first gear 201 and the second gear 202 can be better meshed.

Optionally, the output shaft 203 of the second gear 202 comprises: a body 204 configured with at least one planar structure; an adjusting part 205 formed by extending from the end of the body 204 along the axial direction, one end of the adjusting part 205 is connected with the body 204, and the other end is configured with a convex clamping part 206; the engaging portion 206 and the body 204 define an adjustable space 207, so that the engaging portion 206 can move to engage with the air guiding plate.

Wherein the mounting seat is configured with a through opening, and the shape of the through opening is matched with the shape of the second gear 202 shaft. That is, the inner sidewall of the through-opening is configured with a planar configuration that matches the body 204. Thus, under the condition that the output shaft 203 rotates, the output shaft 203 drives the mounting seat to synchronously rotate, and therefore the overturning motion of the air deflector is achieved.

In practice, the body 204 may be configured in a plurality of planar configurations. Therefore, under the condition that the output shaft 203 drives the air deflector to perform overturning motion, the stability of connection between the output shaft 203 and the mounting seat can be improved, and the phenomenon of slipping is prevented.

The output shaft 203 of the second gear 202 is clamped with the mounting seat of the air deflector through the adjusting part 205. In the process of assembling output shaft 203 and mount pad, the through-hole of mount pad is aimed at to output shaft 203, and the planar structure of body 204 is corresponding with the position of the planar structure who runs through the hole, output shaft 203 removes, joint portion 206 receives the extrusion of running through the mouthful lateral wall, be close to body 204, adjustable space 207 diminishes, joint portion 206 is through running through the hole after, joint portion 206 resets, adjustable space 207 grow, joint portion 206 and the joint that runs through the hole opposite side, thereby it is fixed with the joint of the mount pad of aviation baffle to realize output shaft 203 of second gear 202.

The rotating assembly 20 is disposed in the accommodating cavity 102 of the pushing portion 101 and moves synchronously with the pushing portion 101. In the moving process of the air deflector, the pushing portion 101 drives the rotating assembly 20 and the air deflector to extend or retract along a straight line. Wherein, the state that the air deflector is in a closed air outlet is defined as an initial state; under the condition that pushing part 101 drives runner assembly 20 and aviation baffle and stretch out along the rectilinear direction, pushing part 101 stretches out to predetermineeing the distance, and runner assembly 20 drive aviation baffle is rotatory, and the aviation baffle rotates relatively to pushing part 101 to realize the regulation of air supply direction, realize the multi-angle air supply. Under the condition that the pushing portion 101 is about to drive the rotating assembly 20 and the air deflector to retract along the linear direction, the rotating assembly 20 drives the air deflector to rotate to the initial state, then, the pushing portion 101 drives the rotating assembly 20 and the air deflector to retract along the linear direction, and the air deflector closes the air outlet.

In addition, in the embodiment of the present application, when the pushing portion 101 moves, the rotating assembly 20 can move along with the pushing portion 101 according to actual conditions to drive the air deflector to rotate. For example, in the movement process that the pushing part 101 drives the air deflector to extend out of the indoor unit, one side of the rotating assembly 20 extends out synchronously, and the other side drives the air deflector to rotate. Therefore, the air deflector can be turned to a preset angle under the condition that the air deflector extends to a preset position, so that the movement time of the air deflector from an initial state to a preset state is shortened. Similarly, during the movement process that the pushing part 101 drives the air deflector to retract into the indoor unit, one side of the rotating assembly 20 retracts synchronously, and the other side drives the air deflector to rotate.

Alternatively, the pushing part 101 is a plate-shaped structure. Alternatively, the protruding end of the pushing part 101 forms a receiving cavity 102 along an expanded configuration perpendicular to the plate surface of the pushing part 101 so as to dispose the rotating assembly 20.

The wiring grooves 104 are arranged along the linear motion direction of the pushing portion 101, and the wiring grooves 104 are formed by being recessed inward from the surface of the pushing portion 101 and are communicated with the accommodating cavity 102. Thus, after the motor of the rotating assembly 20 is arranged in the accommodating cavity 102, the power line of the motor can be arranged towards the wiring groove 104 along the accommodating cavity 102, and the power line is accommodated in the wiring groove 104, so that the power line is prevented from interfering with the movement of the pushing part 101. Secondly, the opening direction of the wiring groove 104 is the same as the opening direction of the accommodating cavity 102, so that direct operation and observation of the condition of the motor and the power line can be facilitated.

Optionally, the depth of wire groove 104 is less than or equal to the depth of receiving cavity 102. Alternatively, one end of wire groove 104 communicates with receiving cavity 102, and the other end is open. Thus, the power line of the motor is conveniently connected with an external lead. In the embodiment of the application, the power line of the motor not only has a conductive function, but also has a data transmission function. For example, the controller of the indoor unit transmits an instruction through a power line to control the motor to work.

Optionally, the connecting rod assembly further comprises: wire pressing cover plate 40 is detachably connected to pushing portion 101, and wire pressing cover plate 40 covers wiring groove 104 to prevent the power cord from being exposed.
