In existing technology, each damper blade of the vent is connected to a corresponding motor, which drives a connecting rod mechanism to control the left and right oscillation of each blade. This approach, using multiple motors to drive each damper blade, is costly and has low control efficiency. Utility Model Content

[0003] This application provides a damper blade control device to solve the technical problems of high driving cost and low control efficiency of existing damper blades, thereby reducing the driving cost of damper blades and improving the control efficiency of damper blades.

[0010] In an optional embodiment of this application, the first drive groove is an arc-shaped groove and its axis is parallel to the axis of the drive disk. The second drive groove includes a drive section and a clearance section connected sequentially along the first rotation direction. The clearance section is arc-shaped and its axis coincides with the axis of the drive disk. The drive section extends radially along the drive disk and is used to push the second blade to move along the second guide groove.

[0011] In an optional embodiment of this application, the air supply duct includes a first air duct and a second air duct arranged in parallel, with the air outlet of the first air duct inclined in a first direction and the air outlet of the second air duct inclined in a second direction.

Figures 2b-3b - Figures 4b-5b The process of change is illustrated, showing the rotation of the first blade 12 and the second blade 13 within the air duct 2 during the clockwise rotation of the drive disk 7. Reversibly, Figures 5b-4b - Figures 3b-2b The process of change shows the rotation of the first blade 12 and the second blade 13 within the air supply duct 2 during the counterclockwise rotation of the drive disk 7.

[0025] According to one aspect of this application, a damper blade control device is provided for controlling the airflow direction of an automotive air conditioner. Figure 1a As shown, the control device includes a housing 1, at least one damper blade 4, and a drive disc 7. The housing 1 has an air supply duct 2 inside and a guide groove 3. The damper blade 4 is disposed within the air supply duct 2 and can rotate about a rotation axis 5. A limiting post 6 is provided on the damper blade 4. The drive disc 7 covers the guide groove 3 and can rotate about its own axis. A drive groove 8 is provided on the drive disc 7. The limiting post 6 passes through the guide groove 3 and is inserted into the drive groove 8. When the drive disc 7 rotates, the drive groove 8 can drive the limiting post 6 to move within the guide groove 3, thereby driving the damper blade 4 to rotate.

[0026] By adopting the above technical solution, the limiting post 6 on the damper blade 4 is inserted into the guide groove 3 on the housing 1, so that the limiting post 6 can drive the damper blade 4 to rotate when moving along the guide groove 3, thereby closing and opening the air duct. By setting a drive disk 7 with a drive groove 8 outside the housing 1 and inserting the limiting post 6 into the drive groove 8, the operator can drive the damper blade 4 to rotate by rotating the drive disk 7. In this application, the number of damper blades 4 can be multiple. It is only necessary to set the limiting post 6 on each damper blade 4, set the guide groove 3 corresponding to each damper blade 4 on the housing 1, and set the drive groove 8 corresponding to each damper blade 4 on the drive disk 7, so that the same drive disk 7 can drive multiple damper blades 4 to rotate. This reduces the number of drive motors used, reduces the driving cost of the damper blades 4, and improves the control efficiency of the damper blades 4.

[0027] In the above scheme, the number of damper blades 4 is preferably multiple, and the housing 1 is provided with an air supply duct 2 that runs through it along its length direction X (e.g., Figure 1a As shown), the air supply duct 2 has multiple guide grooves 3 on one side wall that penetrate the housing 1 along its width direction Y (as shown). Figure 1b (As shown). Each damper blade 4 is located within the air supply duct 2, and each damper blade 4 has a rotation axis 5 extending along the width direction Y and is capable of rotating around its respective rotation axis 5 (e.g., Figure 1a (As shown). Specifically, the damper blade 4 includes a rotating shaft extending along the width direction Y, and the rotation axis 5 is the axis of the rotating shaft. Each damper blade 4 corresponds to a guide groove 3, and each damper blade 4 is provided with a limiting post 6 extending along the width direction Y (as shown). Figure 1b (As shown). Reference Figure 6 The axis of each limiting post 6 (located at the center of the circular end face of the limiting post 6 and perpendicular to the plane of the paper) is parallel to its corresponding rotation axis 5 (located at the center of the circular cross-section of the rotation axis and perpendicular to the plane of the paper). The limiting post 6 passes through the guide groove 3 and protrudes outside the housing 1. The drive disk 7 is located on the outside of the side wall where the guide groove 3 is located and can rotate around its own axis under the drive of the motor. The drive disk 7 has multiple drive grooves 8, and each drive groove 8 corresponds to a guide groove 3. The end of the limiting post 6 away from the housing 1 is inserted into the drive groove 8. When the drive disk 7 rotates, the drive groove 8 can drive the limiting post 6 to move within the guide groove 3, thereby driving the damper blade 4 to rotate.

[0028] Furthermore, such as Figure 2b , Figure 3b , Figure 4b and Figure 5b As shown, the air supply duct 2 has a partition 9 at its midpoint along its height direction Z, dividing the air supply duct 2 into a first air duct 10 and a second air duct 11. The air outlet of the first air duct 10 is inclined in a first direction (the downward direction in Figures 2 to 5), and the air outlet of the second air duct 11 is inclined in a second direction (the upward direction in Figures 2 to 5). (Reference) Figure 2b When the second air duct 11 is closed and the first air duct 10 is open, airflow a flows out from the first air duct 10 and is directed downwards by the air outlet of the first air duct 10. (Reference) Figure 3bWhen the first air duct 10 and the second air duct 11 are simultaneously open, airflow b1 flows out of the first air duct 10 and is directed downwards by the outlet of the first air duct 10. Airflow b2 flows out of the second air duct 11 and is directed upwards by the outlet of the second air duct 11. Airflows b1 and b2 interact at the outlet to form a composite airflow b3. The direction of the composite airflow b3 is determined by the magnitudes of airflows b1 and b2 and the structure of the first air duct 10 and the second air duct 11. The following description uses the example of mirror-symmetric structures of the first air duct 10 and the second air duct 11. When the velocity of airflow b1 is greater than the velocity of airflow b2, the composite airflow b3 is directed downwards, and the greater the velocity difference between airflows b1 and b2, the greater the degree of inclination of the composite airflow b3. Similarly, when the velocity of airflow b2 is greater than the velocity of airflow b1, the composite airflow b3 is directed upwards. The flow velocities of airflows b1 and b2 are related to the degree of closure of the first air duct 10 and the second air duct 11. For example, the flow velocity of airflow b1 is maximum when the first air duct 10 is completely open, and zero when the first air duct 10 is completely closed. (Reference) Figure 4b When the first air duct 10 is completely closed, the airflow c flows out from the second air duct 11. Under the guidance of the air outlet of the second air duct 11, the airflow c is tilted upward and sent out.

[0029] Furthermore, the damper blades 4 are two in number: a first blade 12 and a second blade 13. The rotation axes 5 of the first blade 12 and the second blade 13 coincide and are located between the first air duct 10 and the second air duct 11. The first blade 12 and the second blade 13 cooperate to adjust the airflow direction at the outlet of the air supply duct 2. The first blade 12 is used to close or open the first air duct 10 and the second air duct 11, and to adjust the proportion of airflow entering the first air duct 10 and the second air duct 11. The second blade 13 is used to close or open the second air duct 11. (Reference) Figure 2b When the first blade 12 rotates to its lowest position and contacts the bottom surface of the air supply duct 2, it can close the second air supply duct 11, allowing the airflow entering the air supply duct 2 to completely enter the first air supply duct 10. (Reference) Figure 4b When the first blade 12 rotates to its uppermost position and contacts the top surface of the air supply duct 2, it can close the first air duct 10. When the second blade 13 rotates to its uppermost position and contacts the top surface of the second air duct 11, it can completely open the second air duct 11. (Reference) Figure 5b When the first blade 12 rotates to the top and contacts the top surface of the air duct 2, it can close the first air duct 10. When the second blade 13 rotates to the top and contacts the top surface of the second air duct 11, it can fully open the second air duct 11, so that the rear air vent of the car stops supplying air.

[0030] Furthermore, the guide groove 3 is arc-shaped and its axis coincides with the rotation axis 5, while the axis of the limiting post 6 is parallel to the rotation axis 5. The axis of the drive disc 7 is parallel to the rotation axis 5, and when the drive disc 7 rotates, the inner wall of the drive groove 8 can push the limiting post 6 to move within the guide groove 3. Specifically, as shown... Figure 2b , Figure 3b , Figure 4b and Figure 5b As shown, the limiting post 6 includes a first limiting post 14 disposed on the first blade 12 and a second limiting post 15 disposed on the second blade 13. The guide groove 3 includes a first guide groove 16 and a second guide groove 17. The first limiting post 14 is inserted into the first guide groove 16, and the second limiting post 15 is inserted into the second guide groove 17. Both the first guide groove 16 and the second guide groove 17 are arc-shaped grooves, and their arc axes coincide with the rotation axis 5. The first limiting post 14 is inserted into the first guide groove 16, and the second limiting post 15 is inserted into the second guide groove 17. When the first blade 12 rotates around the rotation axis 5, the first limiting post 14 moves along the first guide groove 16; when the second blade 13 rotates around the rotation axis, the second limiting post 15 moves along the second guide groove 17, thereby improving the stability of the rotation of the first blade 12 and the second blade 13. Figure 2b , Figure 3b , Figure 4b and Figure 5b As shown, the drive groove 8 includes a first drive groove 18 and a second drive groove 19. The end of the first limiting post 14 passes through the first guide groove 16 and is inserted into the first drive groove 18; the end of the second limiting post 15 passes through the second guide groove 17 and is inserted into the second drive groove 19. When the drive disk 7 rotates, the side wall of the first drive groove 18 can press against the first limiting post 14, causing the first limiting post 14 to move within the first guide groove 16. The side wall of the second drive groove 19 can press against the second limiting post 15, causing the second limiting post 15 to move along the second guide groove 17. Specifically, a connecting shaft 23 is provided on the side of the drive disk 7 away from the housing 1. The axis of the connecting shaft 23 coincides with the axis of the drive disk 7 (located at the center of the drive disk 7 and perpendicular to the plane of the paper). The connecting shaft 23 is connected to the drive end of the drive motor. The drive motor is used to drive the drive disk 7 to rotate, and through the drive disk 7, it drives the first blade 12 and the second blade 13 to rotate. In this example, a single drive motor is used to rotate two damper blades 4, avoiding the need for a separate drive motor for each damper blade 4 in existing technologies. This saves on drive costs and improves control efficiency.

[0031] Furthermore, such as Figure 2b , Figure 3b , Figure 4b and Figure 5bAs shown, the first drive groove 18 is an arc-shaped groove with its axis parallel to the axis of the drive disk 7. The axis of the drive disk 7 is parallel to the rotation axis 5. The first drive groove 18 intersects with the first guide groove 16. The first drive groove 18 gradually moves away from the axis of the drive disk 7 along the radial direction of the drive disk 7, so as to cooperate with the first guide groove 16 to drive the first limiting post 14 to move within the first guide groove 16. (Reference) Figure 2a and Figure 5a The two ends of the first drive groove 18 correspond to the two ends of the first guide groove 16. Preferably, the first drive groove 18 is an arc-shaped groove and its arc axis is parallel to the axis of the drive disk 7. Making the first drive groove 18 arc-shaped allows the movement direction of the first limiting post 14 to be approximately perpendicular to the side wall of the first drive groove 18, improving the stability of the force applied by the first drive groove 18 to the first limiting post 14. The drive segment 191 gradually moves away from the axis of the drive disk 7 in a counterclockwise direction. Preferably, the drive segment 191 extends radially along the drive disk 7.

[0032] Furthermore, such as Figure 2b , Figure 3b , Figure 4b and Figure 5b As shown, the second drive groove 19 intersects with the second guide groove 17. The second drive groove 19 includes a drive section 191 and a clearance section 192 connected sequentially in a clockwise direction. The clearance section 192 is an arc-shaped groove, and its arc axis coincides with the axis of the drive disk 7. (Reference) Figures 2b-3b - Figure 4b The change process ensures that when segment 192 passes the second limiting post 15, no force is applied to the second limiting post 15, keeping the second blade 13 on the top surface of the second air duct 11, thus fully opening the second air duct 11. (Reference) Figures 4b-5b During the change process, the drive section 191 extends radially along the drive disk 7. When the drive section 191 passes the second limiting post 15, it applies a thrust to the second limiting post 15, causing the second limiting post 15 to move within the second guide groove 17.

[0033] Furthermore, such as Figure 2a , Figure 3a , Figure 4a and Figure 5a As shown, a stop block 20 is provided on the outer peripheral surface of the drive disk 7, and a first limiting block 21 and a second limiting block 22 are provided on the housing 1 in a clockwise direction. The stop block 20 is located between the first limiting block 21 and the second limiting block 22. The first limiting block 21 and the second limiting block 22 are used to block the stop block 20 to limit the rotation range of the drive disk 7. Preferably, as Figure 2a , Figure 3a , Figure 4a and Figure 5a As shown, a first position and a second position are arranged sequentially in a clockwise direction between the first limiting block 21 and the second limiting block 22 (the first position is...). Figure 3a The stop block 20 is located at the second position. Figure 4a The location of the stop block 20). When the stop block 20 contacts the first limit block 21 ( Figure 2a ), the first blade 12 seals the second air duct 11 ( Figure 2b When the stop block 20 moves to the first position, the first blade 12 is parallel to the length direction X, and both the first air duct 10 and the second air duct 11 are open. When the stop block 20 moves to the second position, the first blade 12 closes the first air duct 10. When the stop block 20 contacts the second limiting block 22, the first blade 12 remains closed to the first air duct 10, and the second blade 13 closes the second air duct 11. It should be emphasized that the drive disc 7 rotates continuously, and the position of the stop block 20 is not limited to... Figure 2a , Figure 3a , Figure 4a and Figure 5a The location shown in the figure Figure 2a , Figure 3a , Figure 4a and Figure 5a The position of the stop block 20 only corresponds to Figure 2b , Figure 3b , Figure 4b and Figure 5b The first blade 12 and the second blade 13 are in special positions. When the stop block 20 moves to other positions, it can adjust the opening degree of the first air duct 10 and the second air duct 11 opened by the first blade 12 and the second blade 13, so as to adjust the speed of the airflow in the first air duct 10 and the second air duct 11, thereby changing the direction of the airflow output from the air outlet.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
