As shown in fig. 3, the embodiment of the present invention is an improvement based on the existing combination of the blade 10 and the connecting rod 8. The blades 10 are typically comprised of several and are spaced apart along the length of the tie bar 8. The rotating shaft of each blade 10 is fixed, the blades 10 rotate around the rotating shaft of each blade, the rotating shaft of each blade 10 is perpendicular to the length direction of the connecting rod 8 and deviates from the connecting rod 8 in the front-back direction, and the connecting rod 8 drives the blades 10 to swing left and right. The rotation shaft of the blade 10 is fixed to the link 8 by a link 11. One end of the connecting rod 11 is fixed with the connecting rod 8, and the other end of the connecting rod is fixed with the end part of the rotating shaft of the blade 10.
To realize the rotation of the blade 10 around its own rotation axis, the connecting rod 11 is driven by the connecting rod 8 and further drives the blade 10 to rotate. Since the position of the rotating shaft of the blade 10 is not changed, the connecting rod 8 and the connecting rod 11 rotate relative to the rotating shaft of the blade 10.
Need realize above-mentioned effect, the utility model discloses a specific embodiment has proposed following structure:
the base 2 is provided with a motor 1 and a driving rotating shaft 3, and of course, the base also comprises a connecting rod connecting piece 4, a connecting rod 8 and a blade 10.
The motor 1 is fixed relative to the base 2, and an output shaft 5 of the motor 1 is meshed with the driving rotating shaft 3.
The connecting rod connecting sheet 4 is provided with a driving groove 7, and the driving rotating shaft 3 is sleeved in the driving groove 7.
The blade 10 is arranged on the connecting rod 8, the rotating shaft of the blade 10 is axially fixed relative to the base 2, and the rotating shaft of the blade 10 is parallel to the output shaft 5 of the motor 1.
As shown in fig. 4, the connecting rod 8 is attached to the connecting rod web 4 by means of a fixing point 9. Or the connecting rod 8 and the connecting rod connecting piece 4 are designed into an integral structure.
Above-mentioned structure, in case motor 1 starts, motor 1's output shaft 5 drives drive pivot 3 and rotates around motor 1's output shaft 5, and drive pivot 3 overlaps again and establish in the drive groove 7 of connecting rod connection piece 4, consequently, drive pivot 3 drives connecting rod connection piece 4 and takes place the arc motion, finally makes blade 10 rotate around self pivot. If the left-right swinging of the blade 10 is to be realized, only the rotating direction of the motor 1 needs to be controlled.
In some preferred embodiments, the connecting rods 8 are symmetrically arranged on both sides of the connecting rod connecting piece 4, and the output shaft 5 of the motor 1 is arranged on the symmetrical plane. Thus, one motor 1 can synchronously control the blades 10 on two sides at the same time, and the efficiency is high.
As shown in fig. 4, the connecting rod connecting piece 4 according to the embodiment of the present invention is preferably a left-right symmetrical structure.
The driving groove 7 has various forms, and the transmission of the motion is not influenced in the motion angle range of the blade 10. The inventors therefore present a design method for the drive socket 7 that meets the above requirements as follows: an intersection line between the symmetry plane and the connecting rod connecting piece 4 is defined as a symmetry axis, and the driving grooves 7 are at least arranged along the direction of the symmetry axis. The length of the directional arrangement needs to be designed comprehensively according to the rotation angle, the size of parts and the like.
As shown in fig. 4, the driving slot 7 is a long strip arranged according to the above requirement, and the arrangement direction of the long strip is along the direction of the symmetry axis.
As shown in fig. 5, the driving slot 7 is U-shaped and arranged according to the above requirement, and the arrangement direction of the U-shape is along the direction of the symmetry axis, i.e. the central axis of the U-shape is located in the direction of the symmetry axis.
In consideration of the bilateral symmetry of the blade 10, the driving slot 7 is preferably arranged with the axis of symmetry in the arrangement direction being bilateral symmetry so that the movement of the driving shaft 3 in the driving slot 7 is left-right coincident.
In order to further reduce the transmission noise between the driving rotating shaft 3 and the driving groove 7 of the motor 1, the driving rotating shaft 3 is coated with foam 6. The driving slot 7 is required to ensure that the driving shaft 3 and the foam 6 are contained in a clearance so as not to generate motion blockage.
The principle of the present invention will be described below by taking the driving groove 7 as a long strip as an example. FIG. 6, O1C is a straight line formed by the center of the output shaft 5 of the motor 1 in a direction parallel to the axis of symmetry, and the straight line is always in a constant position since the output shaft 5 of the motor 1 rotates only. Defining the starting position of the driving shaft 3 as the center O of the driving shaft 32Is connected with the output shaft 5 center O of the motor 11Is a connecting line O1O2And O1The C directions are overlapped. When the motor 1 rotates a certain angle, the driving shaft 3 moves to the position shown in fig. 6, O2Deviation of O1C, offset distance is O2C。
FIG. 7, in which O is1'C' is a straight line formed by the center of the rotation axis of the blade 10 in a direction parallel to the symmetry axis, and the straight line is always in a constant position since the rotation axis of the blade 10 only rotates. The starting position of the connecting rod 11 is defined as the direction of the connecting rod 11 being at O1At 'C'. When the output shaft 5 of the motor 1 rotates by a certain angle as shown in fig. 6, the connecting rod 11 moves to the position shown in fig. 7, and the connecting point between the connecting rod 11 and the connecting rod 8 is O2', offset distance is O2’C’。
Due to O1O2And O1’O2' all are of fixed length and from the structural relationship, O is known2C and O2The 'C's are simultaneously equal, and therefore, there is O2C＝O1O2sinw1t＝O2’C’＝O1’O2’sinw2t, wherein w1Is the angular velocity, w, at which the output shaft 5 of the motor rotates2Is the angular velocity at which the blade 10 rotates. Therefore, by setting the angular velocity of the left and right rotations of the motor 1, the angular velocity of all the blades 10 can be calculated.
When the drive channel 7 is U-shaped, it is within the ability of the person skilled in the art to make appropriate designs based on basic mechanical design principles, e.g. selecting a suitable O1O2U-groove size and O1’O2' the movement of the blade 10 by the motor 1 can still be realized, and will not be described in detail herein.
The automobile with the electric air outlet is simple and efficient in air outlet design, is not prone to noise generation, and can replace the traditional complex air outlet design.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention. The present invention is intended to cover by those skilled in the art various modifications and adaptations of the invention without departing from the spirit and scope of the invention. Therefore, the protection scope of the present invention is subject to the claims.
