Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the implementation of this invention,

[0038] like Figure 1 A schematic diagram of the electric air outlet structure in an embodiment of the present invention is shown. Figure 2 The diagram shows another angle view of the electric air vent structure in an embodiment of the present invention. The present invention provides an electric air vent structure for an automotive dashboard, including an air vent housing 60.

[0039] The upper blade mechanism 10, the lower blade structure 20, the blade 30, and the drive mechanism 40 are all installed inside the air outlet housing 60;

[0040] The air vent housing 60 is a through housing, with one end of the air vent housing 60 being an air outlet and the other end being an air inlet;

[0041] An upper blade mechanism 10 is installed inside the air outlet housing 60. The upper blade mechanism 10 is located at one end of the air outlet of the air outlet housing 60. The upper blade mechanism 10 is used to adjust the vertical angle of the air outlet.

[0042] A lower blade structure 20 is installed inside the air outlet housing 60, and the lower blade structure 20 is located at one end of the air inlet of the air outlet housing 60; a blade 30 is rotatably installed on the lower blade structure 20, there are at least two blades 30, and multiple blades 30 are arranged in a linear array; the blades 30 are controlled by the lower blade structure 20 to adjust the left and right angle of the air outlet.

[0043] A drive mechanism 40 is provided on the outside of the air outlet housing 60. The drive mechanism 40 drives the upper blade mechanism 10 and the lower blade structure 20 to adjust the air outlet angle.

[0044] In the above embodiment, another optional implementation is that there are two drive mechanisms 40, which are used to drive the upper blade mechanism 10 and the lower blade structure 20 respectively; the drive mechanism 40 is used to drive the upper blade mechanism 10 and the lower blade structure 20 to work, thereby realizing automatic adjustment of the air outlet angle.

[0045] One drive mechanism 40 is located on the side of the upper blade mechanism 10. The drive mechanism 40 is directly connected to the upper blade mechanism 10 and provides power to rotate the upper blade mechanism 10, thereby adjusting the vertical angle of the air outlet. The other drive mechanism 40 is located below or above the lower blade structure 20 and is directly connected to the lower blade structure 20. The drive mechanism 40 provides power to rotate the blades 30 installed on the lower blade structure 20, thereby adjusting the horizontal angle of the air outlet.

[0046] In this invention, the upper blade mechanism 10 includes an upper blade body 11 and an upper blade mounting block 13;

[0047] There are two upper blade mounting blocks 13, which are located on both sides of the upper blade body 11 and are fixedly connected to the air outlet housing 60.

[0048] The upper blade body 11 is rotatably mounted on two upper blade mounting blocks 13 via transmission pins 15 at both ends.

[0049] The upper blade body 11 rotates around the transmission pin 15 as an axis.

[0050] In this invention, the ventilation cavity of the upper blade body 11 is provided with a partition plate 113, and there is at least one partition plate 113; the partition plate 113 divides the ventilation cavity of the upper blade body 11 into multiple ventilation holes; the partition plate 113 is used to reinforce the upper blade body 11.

[0051] In the above embodiments, another optional implementation is that when there is only one partition plate 113, it is located in the middle of the upper blade body 11. The partition plate 113 divides the upper blade body 11 into two ventilation holes. An upper blade trim 12 is provided on the side of the partition plate 113 away from the lower blade structure 20. The upper blade trim 12 serves a decorative and aesthetic purpose.

[0052] In the above embodiments, another optional implementation is that when there is only one horizontal partition plate 113 and one vertical partition plate 113, it is located in the middle of the upper blade body 11. The horizontal partition plate 113 and the vertical partition plate 113 form a cross shape, dividing the upper blade body 11 into four ventilation holes. The horizontal partition plate 113 and the vertical partition plate 113 are provided with an upper blade trim 12 on the side away from the lower blade structure 20. The upper blade trim 12 serves a decorative and aesthetic purpose.

[0053] In this invention, an upper blade trim 12 is provided on the outer end of the partition plate 113, and the upper blade trim 12 is located at the air outlet end of the air outlet housing 60.

[0054] The upper leaf trim 12 serves a decorative purpose, making the partition 113 more aesthetically pleasing.

[0055] The upper blade trim 12 can be connected to the spacer plate 113 by screws.

[0056] The partition 113 is provided with a slot 111 and a limiting hole 112. The upper leaf trim 12 is provided with a buckle 121 and a limiting post 122. In use, by aligning the buckle 121 with the slot 111 and the limiting hole 112 with the limiting post 122, the upper leaf trim 12 is pressed onto the partition 113, and the buckle 121 is engaged with the slot 111, thereby achieving connection and improving connection efficiency. At the same time, since there are no screws, the aesthetics of the upper leaf trim 12 are maintained. Since no glue is used, environmental protection in the vehicle interior is achieved.

[0057] In this invention, dampers 16 and upper blade drive shafts 14 are respectively installed at both ends of the upper blade body 11.

[0058] The outer end of the damper 16 is slidably installed in the arc-shaped groove on the upper blade mounting block 13 on the side away from the upper blade rotation shaft 17; the damper 16 plays a role in deceleration and prevents the upper blade body 11 from rotating too fast and causing injury to the user.

[0059] The outer end of the upper blade drive shaft 14 is slidably mounted in an arc-shaped groove on the upper blade mounting block 13 near the upper blade rotation shaft 17. The blade drive shaft 14 is used to drive the upper blade body 11 to rotate.

[0060] In this embodiment of the invention, the upper blade mechanism 10 further includes an upper blade rotating shaft 17. One end of the upper blade rotating shaft 17 is connected to the drive mechanism 40, and the other end of the upper blade rotating shaft 17 is provided with a groove, in which the upper blade drive shaft 14 is installed. The groove at the other end of the upper blade rotating shaft 17 is a rectangular groove. Since the upper blade body 11 rotates around the transmission pin 15, the upper blade drive shaft 14 rotates around the transmission pin 15. The movement trajectory of the upper blade drive shaft 14 is an arc. The upper blade rotating shaft 17 rotates around the motor axis of the motor 41, but the axis of the motor 41 and the transmission pin 15 are not on the same straight line. Therefore, the groove at the other end of the upper blade rotating shaft 17 is a rectangular groove.

[0061] Specifically, the drive mechanism 40 drives the upper blade rotating shaft 17 to rotate, which in turn drives the upper blade drive shaft 14 to move eccentrically. The upper blade drive shaft 14 is then limited by the arc groove of the upper blade mounting block 13, which in turn drives the upper blade body 11 to rotate around the transmission pin 15, thereby completing the adjustment of the upper and lower angles of the air outlet.

[0062] In this invention, the lower blade structure 20 includes a lower blade connecting rod 21, which is rotatably connected to the blade 30. The lower blade connecting rod 21 is installed inside the air inlet housing 60 and is located at the air inlet end of the air inlet housing 60.
