Fig. 2 is a partial enlarged view at a in fig. 1. Specifically, the air deflection assembly 500 is installed at the air outlet 410 of the housing 400, so as to adjust the air output and/or the air output direction of the air outlet 410 by rotating the air deflection assembly 500 relative to the housing 400.

Referring to fig. 3-8, in some alternative embodiments of the present application, an air deflection assembly 500 includes a connecting shaft 100, an air deflection 200, and a lock sleeve 300. Illustratively, the air deflector 200 may be rotatably connected to the housing 400 via the connection shaft 100, so that the air deflector 200 may rotate relative to the housing 400, thereby adjusting the air output and the air output direction of the air outlet 410.

Referring to fig. 6 and 13, in some alternative embodiments, one of the air deflector 200 and the connecting shaft 100 has a first connecting portion 210, and the other has a second connecting portion 110, and the second connecting portion 110 is in rotation-limited fit with the first connecting portion 210, so that the connecting shaft 100 can drive the air deflector 200 to rotate, thereby adjusting the air output and the air output direction of the air outlet 410.

In an alternative embodiment, as shown in fig. 6 to 13, the wind deflector 200 has a first connection portion 210, and the connection shaft 100 has a second connection portion 110. This embodiment is advantageous in that the size of one end of the connection shaft 100 connected to the wind deflector 200 is reduced, and thus, the connection shaft 100 is advantageously connected to the housing of the air outlet.

In another alternative embodiment, the wind deflector 200 has a second connection portion 110, and the connection shaft 100 has a first connection portion 210.

Referring to fig. 3 to 10, the first end of the lock sleeve 300 is sleeved on the first connection portion 210 and is rotatably engaged with the first connection portion 210, so that the lock sleeve 300 can rotate relative to the first connection portion 210. Further, the sleeve 300 is configured to rotate between a first position and a second position relative to the first connector 210.

Illustratively, the sleeve 300 has a mounting hole that extends through the sleeve 300 from a first end of the sleeve 300 to a second end of the sleeve 300. At least a portion of the first connecting portion 210 is located in the mounting hole, so that a revolute pair is formed between the first connecting portion 210 and an inner side wall of the mounting hole, and the lock sleeve 300 can rotate relative to the first connecting portion 210.

In some alternative embodiments, one of the sleeve 300 and the first connector 210 has a sleeve stop slot 214 and the other has a stop tab 350, the stop tab 350 being at least partially positioned within the sleeve stop slot 214 to define the angle of rotation of the sleeve 300 relative to the first connector 210 via the sleeve stop slot 214 and the stop tab 350. Optionally, the lock sleeve limit groove 214 corresponds to a central angle of 90 °.

In some alternative embodiments, as shown in fig. 19 and 20, when the lock sleeve 300 is in the first position relative to the first connecting portion 210, the limiting protrusion 350 abuts against the first end of the lock sleeve limiting groove 214, and the lock sleeve 300 is fastened to the second connecting portion 110. In the case that the lock sleeve 300 is at the second position with respect to the first connecting portion 210, the limiting protrusion 350 is stopped at the second end of the lock sleeve limiting groove 214, and the lock sleeve 300 is separated from the second connecting portion 110.

The air deflection assembly 500 provided in the above embodiments can be connected to or disconnected from the connection shaft 100 by simply rotating the lock sleeve 300 during the process of disassembly or assembly. Specifically, during the process of installing the air deflector 200, the lock sleeve 300 is rotated to the first position, so that the lock sleeve 300 is fastened to the second connection portion 110, and the air deflector 200 is connected to the connection shaft 100. In the process of disassembling the air deflector 200, the lock sleeve 300 is rotated to the second position, so that the lock sleeve 300 is detached from the second connecting portion 110, thereby detaching the first connecting portion 210 from the second connecting portion 110, and detaching the air deflector 200 from the connecting shaft 100. Therefore, no other tools are needed in the process of installing or detaching the air deflector 200, so that the difficulty in assembling and detaching the air deflector 200 and the connecting shaft 100 is improved, and the convenience in detaching the air deflector 200 is improved.

In addition, during the installation of the air deflector 200, the limiting protrusion 350 may be stopped against the first end of the lock sleeve limiting groove 214, so as to avoid the lock sleeve 300 from being excessively buckled with the second connecting portion 110 due to excessively large or excessively small rotation angle of the lock sleeve 300. Therefore, this embodiment is beneficial to determine the connection state between the lock sleeve 300 and the second connection portion 110, and ensure that the lock sleeve 300 and the second connection portion 110 can be completely fastened during the installation process, so as to avoid the lock sleeve 300 from being insufficiently fastened to the second connection portion 110 and loosening, and thus is beneficial to prevent the air deflector 200 and the connection shaft 100 from loosening.

It should be noted that, during the installation of the air deflector 200, the lock sleeve 300 rotates relative to the first connection portion 210, and when the limiting protrusion 350 is stopped at the first end of the lock sleeve limiting groove 214, the lock sleeve 300 will feel a pause, so that it is beneficial for an operator to sense whether the first fastening portion 310 and the second fastening portion 111 are completely fastened. Specifically, in the case where the lock sleeve 300 cannot rotate relative to the first connecting portion 210 due to the abrupt feeling, the first fastening portion 310 and the second fastening portion 111 are completely fastened. In the case that no abrupt feeling occurs, the first fastening portion 310 and the second fastening portion 111 are not completely fastened.

During the installation of the air deflector 200, the lock sleeve 300 rotates relative to the first connecting portion 210, and when the limiting protrusion 350 is stopped at the second end of the lock sleeve limiting groove 214, the lock sleeve 300 can generate a frustration feeling, so that an operator can sense whether the first fastening portion 310 is completely separated from the second fastening portion 111. Specifically, in the case where a jerk is occurred and the lock sleeve 300 cannot rotate relative to the first connecting portion 210, the first fastening portion 310 is completely separated from the second fastening portion 111. In the case where no abrupt feeling occurs, the first fastening portion 310 is not completely separated from the second fastening portion 111.

In some alternative embodiments of the air deflection assemblies 500 of the present application, the jacket spacing slots 214 are arcuate spacing slots. Further alternatively, the sleeve retainer groove 214 may be a circular arc groove. Illustratively, the center of the circular arc-shaped groove is located on the axis of rotation of the lock sleeve 300 relative to the first connecting portion 210. Alternatively, the lock sleeve 300 rotates about a first axis relative to the first connection portion 210, and the sleeve-retaining groove 214 is disposed about the first axis.

This solution is beneficial to ensure that the width of the sleeve limiting groove 214 in the radial direction of the first connecting portion 210 is consistent, and reduce the processing difficulty of the sleeve limiting groove 214. In addition, the depth of the limiting protrusion 350 embedded into the lock sleeve limiting groove 214 is kept unchanged, and the smoothness of the limiting protrusion 350 sliding along the lock sleeve limiting groove 214 is improved while the two ends of the lock sleeve limiting groove 214 can be limited by the limiting protrusion 350.

In the related art, the air conditioner air deflector is mainly connected and fixed with the rotating shaft through screws, and the air conditioner air deflector and the rotating shaft are mainly made of plastic materials, and the screws are made of metal materials, so that the problem of wire removal easily occurs in the process of repeated disassembly and assembly of the air conditioner air deflector in the related art. In addition, in the process of installing the screw, only the operator senses the tightness of the screw assembly, so that the screw is easily installed too tightly or too loosely due to the difference of operators and the difference of proficiency of operators, and further, the screw is easily loosened or loosened.

Compared with the related art, the air deflector assembly 500 disclosed in the above embodiment does not need to be provided with screws, and the air deflector assembly 500 is fastened to the connecting shaft 100 through the lock sleeve 300 between the air deflector 200 and the connecting shaft 100, so that the problem that the thread is easily removed due to multiple dismounting in threaded connection can be avoided, and an operator can perceive whether the lock sleeve 300 is completely fastened to or completely detached from the second connecting portion 110, so that the tightness of the assembly of the lock sleeve 300 and the second connecting portion 110 is ensured in the process of assembling the air deflector assembly 500. In the process of disassembling the air deflector 200, the forced disassembly caused by incomplete separation of the lock sleeve 300 and the second connecting part 110 is avoided, and the purpose of protecting the lock sleeve 300 and the second connecting part 110 in the buckling structure is achieved.

In some alternative embodiments, the sleeve 300 may be rotatably coupled to the first coupling portion 210. Therefore, in the case that the lock sleeve 300 is at the second position relative to the first connection portion 210, the lock sleeve 300 is prevented from being separated from the first connection portion 210, thereby being beneficial to preventing the lock sleeve 300 from being lost after the air guide plate 200 is detached from the connection shaft 100, and eliminating the need for disassembling and secondarily installing the lock sleeve 300 and the air guide plate 200. Therefore, this embodiment is advantageous in further improving the convenience of assembling and disassembling the air guide plate 200.

The notch of the sleeve stopper 214 is oriented in the same direction as the extending direction of the first axis, that is, the stopper protrusion 350 may be inserted into the sleeve stopper 214 along the extending direction of the first axis. Therefore, the above embodiment can ensure that the relative movement direction of the limit protrusion 350 inserted into the sleeve limit groove 214 is consistent with the relative movement direction of the first connecting portion 210 inserted into the sleeve 300, thereby being beneficial to reducing the difficulty of assembling the sleeve 300 and the first connecting portion 210.
