Abstract
Description
Technical Field
[0001] This invention relates to an automotive air vent, specifically an automotive air vent with a self-driving air sweeping function. Background Technology
[0002] Car air vents are used for exhausting air from inside the vehicle. When in use, outside air or cool air from the air conditioner is exhausted through the vents, and the airflow is guided in one direction by a deflector. Currently, most car air vents are manually adjustable, and the airflow direction is fixed, only able to blow in a specific direction, unable to achieve large-area airflow. Furthermore, manual adjustment is becoming increasingly outdated. Therefore, developing automatic airflow control for car air vents is particularly necessary. Some automatic airflow control devices have already adopted motor-driven systems; however, these devices are prone to failure due to motor malfunctions, requiring maintenance and incurring high costs. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automotive air vent with a self-driving air sweeping function to solve the problems mentioned in the background art.
[0004] A car air vent with self-driven air sweeping function includes a base, an end cap, and a louver assembly. The end cap is fixedly connected to the right end of the base, and the louver assembly is installed inside the end cap. The vent also includes:
[0005] A rotating shaft assembly, wherein there are two sets of rotating shaft assemblies and they are respectively fixed at the front and rear ends of the end cover;
[0006] A sweeping hood is located outside the right side of the end cover and moves through the rotating shaft assembly. The sweeping hood is rotatably connected to the end cover via the rotating shaft assembly. The sweeping hood consists of a horizontal section and an inclined section. The inclined section is integrally connected at the right end of the horizontal section. The opening diameter on the left side of the inclined section is equal to the opening diameter on the right side of the horizontal section, and the opening diameter on the right side of the inclined section is smaller than the opening diameter on the right side of the horizontal section.
[0007] Specifically, the rotating shaft assembly includes a spherical end and a rod end. The rod end is fixed to an end cap, and the spherical end is fixed to the other end of the rod end. The front and rear end faces of the air sweeper are provided with circular holes, and the spherical end passes through the circular holes and is movably connected to them.
[0008] Specifically, the diameter of the spherical end of the rotating shaft is equal to the diameter of the center of the circular hole, and the diameter of the spherical end of the rotating shaft is larger than the diameter of the openings on both sides of the circular hole.
[0009] Specifically, the inner wall of the circular hole is provided with a ring-shaped channel, and the outer wall of the spherical end of the rotating shaft is provided with a plurality of spring grooves evenly distributed in a ring shape. A ball seat is slidably connected inside the spring groove. An inner spring is connected between the inner end of the ball seat and the bottom of the spring groove. A rolling groove is provided at the outer end of the ball seat. A ball is slidably connected inside the rolling groove. The ball is slidably connected to the ring channel.

Detailed Implementation
[0024] Please see Figures 1-8 A car air vent with self-driving air sweeping function includes a base 1, an end cap 2 and a louver assembly 9. The end cap 2 is fixedly connected to the right end of the base 1, and the louver assembly 9 is installed inside the end cap 2. The base 1 and the end cap 2 are used for installation with the car, while the louver assembly 9 can guide the airflow inside the end cap 2.
[0025] A car air vent with self-driven air sweeping function also includes:
[0026] The rotating shaft assembly has two sets and is fixed at the front and rear ends of the end cover 2 respectively. The rotating shaft assembly includes a rotating shaft ball end 4 and a rotating shaft rod end 8. The rotating shaft rod end 8 is fixed to the end cover 2, and the rotating shaft ball end 4 is fixed to the other end of the rotating shaft rod end 8.
[0027] The air sweeping hood 3 is located on the right outside of the end cover 2 and is movably connected to the rotating shaft assembly. The air sweeping hood 3 is rotatably connected to the end cover 2 through the rotating shaft assembly. The air sweeping hood 3 consists of a horizontal section 14 and an inclined section 15. The inclined section 15 is integrally connected at the right end of the horizontal section 14. Circular holes 5 are opened on the left and right end faces of the air sweeping hood. The spherical end 4 of the rotating shaft passes through the circular hole 5 and is movably connected to the circular hole 5. The diameter of the spherical end 4 of the rotating shaft is equal to the diameter of the middle opening of the circular hole 5. The diameter of the spherical end 4 of the rotating shaft is larger than the diameter of the openings on both sides of the circular hole 5. Because the spherical end 4 of the rotating shaft can move inside the circular hole 5 of the horizontal section 14 of the air sweeping hood, the air sweeping hood 3 can rotate through the rotating shaft assembly and the end cover 2. However, the range of motion of the air sweeping hood 3 is 40°.
[0028] The inner wall of the circular hole 5 is provided with a ring-shaped channel 10. The outer wall of the spherical end 4 of the rotating shaft is provided with a plurality of spring grooves 11 evenly arranged in a ring shape. A ball seat 12 is slidably connected inside the spring groove 11. An inner spring 13 is connected between the inner end of the ball seat 12 and the bottom of the spring groove 11. A rolling groove is provided at the outer end of the ball seat 12. A ball 7 is slidably connected inside the rolling groove. The ball 7 is slidably connected to the ring-shaped channel 10. When the spherical end 4 of the rotating shaft moves inside the circular hole 5 of the horizontal section 14 of the sweeping hood, the ball 7 in the ball seat 12 can roll with the ring-shaped channel 10. The inner spring 13 gives the ball seat 12 an elastic force, so that the ball 7 and the ring-shaped channel 10 fit tightly together. This can reduce the friction when the sweeping hood 3 rotates, thus making it more conducive to the sweeping hood 3 being blown by the wind and rotating.
[0029] The opening diameter on the left side of the inclined section 15 of the sweeping hood is equal to the opening diameter on the right side of the horizontal section 14 of the sweeping hood, and the opening diameter on the right side of the inclined section 15 of the sweeping hood is smaller than the opening diameter on the right side of the horizontal section 14 of the sweeping hood. The included angle between the inclined section 15 and the horizontal section 14 of the sweeping hood is 160°-170°. Figure 8 As shown, when the lower end of the air outlet is horizontal, the air at the upper end of the air outlet is guided by the inclined section 15 of the sweeping hood and then directed downwards at a 40° angle to the horizontal. This creates a counterclockwise torque on the sweeping hood 3, causing it to rotate counterclockwise. Figure 7 Status, such as Figure 7 As shown, when the upper airflow direction of the air outlet is horizontal, the lower airflow, guided by the inclined section 15 of the sweeping hood, is directed upwards at a 40° angle to the horizontal. This creates a clockwise torque on the sweeping hood 3, causing it to rotate clockwise. Figure 8 This device features automatic air sweeping, which offers a wider coverage area and faster temperature regulation compared to manual sweeping. It is also cost-effective, utilizing wind power to achieve automatic sweeping without any drive source, significantly reducing costs. This device improves the quality of life for drivers and passengers, allowing them to more easily enjoy the convenience and comfort of a car. Both the upper and lower ends of the end cover 2 are fixed with a row of outer springs 6. The ends of the outer springs 6 contact the inner end of the horizontal section 14 of the air sweeping cover. When the air sweeping cover 3 rotates due to wind, the inner side of the horizontal section 14 of the air sweeping cover 3 continuously contacts the upper and lower outer springs 6. The outer springs 6 prevent the air sweeping cover 3 from hitting the upper and lower ends of the end cover 2, thus preventing noise and deformation from frequent hard impacts, thereby extending the service life of the air sweeping cover 3.
