Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.
Example 1
As shown in fig. 1, 2 and 3, a connecting shaft sleeve can be fixedly connected to an air deflector, an adjusting groove 1 allowing a driving motor shaft to extend in is formed in the connecting shaft sleeve, a flat groove 2 matched with the shape of the driving motor shaft is formed in the bottom of the adjusting groove 1, and a driving inclined surface is formed in the side wall of the adjusting groove 1. In the process of assembling the air deflector on the driving motor, the driving motor shaft stretches into the adjusting groove 1, when the driving motor shaft stretches into the adjusting groove 1, the connecting shaft sleeve can drive the driving motor shaft to rotate through the driving inclined plane so as to adjust the rotation angle of the driving motor shaft to enable the driving motor shaft to correspond to the flat groove 2, so that the driving motor shaft is assembled in the flat groove 2, and at the moment, the axis of the driving motor shaft can coincide with the axis of the flat groove 2. Therefore, the rotating angle of the motor shaft can be adjusted, assembly dead angles are eliminated, and the working efficiency is improved.
Specifically, as shown in fig. 3, the depth of the flat groove 2 may be 6 to 8mm. The effective groove depth of the connecting shaft sleeve and the motor is not smaller than 6mm, so that the reliability of the motor and the air deflector in normal operation is ensured.
As an embodiment, as shown in fig. 1, 2, 3, the adjustment groove 1 includes a first groove 11, the driving slope includes a first driving slope 111, the shape of the first groove 11 is a sector shape on a section perpendicular to the axial direction of the flat groove 2, and both side planes of the first groove 11 are the first driving slope 111, that is, both side planes of the first groove 11 are two straight sides on a section perpendicular to the axial direction of the flat groove 2. Thus, when the drive motor shaft extends into the first groove 11, the connecting shaft sleeve can drive the drive motor shaft to rotate through the first drive inclined surface 111, and the rotation angle of the drive motor shaft is adjusted.
Preferably, the center of the fan-shaped cross section of the first groove 11 extends along the axial direction of the flat groove 2 to form a central axis of the first groove 11, and the central axis coincides with the axial line of the flat groove 2. More preferably, the angle between the two first drive inclined surfaces 111 of the first groove 11 is 60 °, i.e. the cross section of the first groove 11 is a sector with a central angle of 60 ° in the direction perpendicular to the direction in which the drive motor shaft extends.
Specifically, the depth of the first groove 11 is 3 to 5mm in the axial direction of the flat groove 2. Thus, when the driving motor shaft stretches into the first groove 11, the first driving inclined plane 111 can effectively drive the driving motor shaft to rotate, and meanwhile, the excessive depth of the first groove 11 can be avoided, so that the overall size of the connecting groove is increased.
Further, the adjusting groove 1 includes a second groove 12 penetrating the first groove 11, the driving inclined surface includes a second driving inclined surface 121, the shape of the second groove 12 is a sector shape on a section perpendicular to the axial direction of the flat groove 2, and both side planes of the second groove 12 are the second driving inclined surface 121, that is, both side planes of the second groove 12 are two straight sides on a section perpendicular to the axial direction of the flat groove 2. Thus, when the drive motor shaft extends into the second groove 12, the connecting sleeve can drive the drive motor shaft to rotate through the second driving inclined surface 121 so as to adjust the rotation angle of the drive motor shaft.
As an embodiment, the first groove 11 and the second groove 12 are symmetrical about the axis of the flat groove 2. Thus, when the cross section of the first groove 11 is a sector having a center angle of 60 °, the cross section of the second groove 12 is also a sector having a center angle of 60 ° and the depth is the same as that of the first groove 11. In the process of assembling the air deflector on the driving motor, when the angle of the driving motor shaft is out of the normal rotation angle range (150-180 DEG) of the air deflector, the flat shaft of the driving motor is positioned at an assembling dead angle, and the flat groove of the connecting shaft sleeve cannot be directly rotated to the same angle as the flat shaft of the motor. The sections of the first groove 11 and the second groove 12 are fan-shaped with the central angle of 60 degrees, so that the assembling angle of the air deflector can be increased by 60 degrees, the whole assembling angle reaches 210 degrees from 150 degrees, and the assembling requirement of the driving motor shaft is larger than 180 degrees.
Example two
As shown in fig. 4, a driving structure of an air deflector comprises an air deflector body 3, a driving motor 5 and a connecting shaft sleeve 4, wherein the connecting shaft sleeve 4 is fixedly connected to the air deflector body 3, and the driving motor 5 is connected to the connecting shaft sleeve 4. The connecting sleeve 4 has the same technical features as the connecting sleeve described in the first embodiment, and therefore, the specific technical features of the connecting sleeve 4 will not be described herein.
Specifically, the air deflector body 3 and the connecting shaft sleeve 4 are integrally formed, but the invention is not limited thereto, and any mode that can realize the fixed connection of the air deflector body 3 and the connecting shaft sleeve 4 may be adopted.
In order to achieve the object, another aspect of the present invention provides an air conditioner, including the driving structure of the air deflector described in the second embodiment.
The embodiment of the invention has the advantages that the rotation angle of the motor shaft can be adjusted, so that the assembly dead angle is eliminated, and the working efficiency is improved.
The above description is only an example of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
