Description

Technical Field

[0001] This invention relates to the field of automotive air vent technology, specifically to a three-channel air vent switching mechanism. Background Technology

[0002] With the development of automotive technology, car air vents have more and more functions. For example, multiple air ducts can be designed in one air vent, and these air ducts can have different air outlet directions and blow out different types of air, thereby meeting the personalized needs of users.

[0003] Chinese invention patent application CN 115257282 A discloses an air vent structure for an air conditioner and a car. The structure mainly includes a housing, which is divided into a first air guide channel, a second air guide channel, and a third air guide channel. A baffle control motor and a deflector control motor are located on one side of the housing, respectively used to internally control the baffle and deflector. Under the control of the baffle control motor, the baffle controls the airflow from the first and third air guide channels by swinging. Under the control of the deflector control motor, the deflector controls the airflow from the second air guide channel by swinging. Thus, two motors control three air ducts. However, the installation space for air vents inside a car is limited. Installing two motors on the outside of the housing, along with their corresponding control systems, results in a large space occupation and high overall cost. Summary of the Invention

[0004] The problem to be solved by the present invention is to provide a three-channel air outlet switching mechanism that occupies less space, has lower cost, and can realize multiple air outlet modes.

[0005] The technical solution adopted by the present invention to solve the above problems is: a three-channel air outlet switching mechanism, including a protective shell fixedly connected to one side of the air outlet housing, an actuator fixedly connected inside the protective shell, a first blade and a second blade disposed on one side of the protective shell and located inside the air outlet housing, and a transmission structure.

[0006] The first blade includes an upper first blade and a lower first blade arranged vertically; the upper first blade and the lower first blade control the airflow of a duct by opening and closing in opposite directions; the second blade includes an upper second blade and a lower second blade; the upper second blade is rotatably connected to the upper first blade, and the lower second blade is rotatably connected to the lower first blade; the upper second blade controls the airflow of a duct by rotating; the lower second blade controls the airflow of a duct by rotating.

[0054] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0055] Please see Figure 1-16 A three-channel air outlet switching mechanism includes a protective shell 1 fixedly connected to one side of the air outlet housing, an actuator 2 fixedly connected inside the protective shell 1, a first blade 3 and a second blade 4 disposed on one side of the protective shell 1 and located inside the air outlet housing, and a transmission structure 5.

[0056] The first blade 3 includes an upper first blade 3a and a lower first blade 3b arranged vertically; the upper first blade 3a and the lower first blade 3b control the air outlet of a duct by opening and closing in opposite directions; the second blade 4 includes an upper second blade 4a and a lower second blade 4b; the upper second blade 4a is rotatably connected to the upper first blade 3a, and the lower second blade 4b is rotatably connected to the lower first blade 3b; the upper second blade 4a controls the air outlet of a duct by rotating; the lower second blade 4b controls the air outlet of a duct by rotating.

[0057] The transmission structure 5 includes a drive disk 51 rotatably connected inside the protective shell 1 and driven by the actuator 2, and a first transmission part 52 and a second transmission part 53 disposed outside the protective shell 1 and driven by the drive disk 51; the first transmission part 52 is used to drive the upper first blade 3a and the lower first blade 3b to open and close in opposite directions; the second transmission part 53 is used to drive the upper second blade 4a and the lower second blade 4b to rotate respectively.

[0058] In practical use, the present invention includes a protective shell 1, which can be fixed to one side of the outer shell of the air outlet, providing a carrier for the actuator 2, the first blade 3, the second blade 4, and the transmission structure 5; the transmission structure 5 includes a drive disk 51 driven by the actuator 2, a first transmission part 52, and a second transmission part 53. The first blade 3 includes an upper first blade 3a and a lower first blade 3b, and the second blade 4 includes an upper second blade 4a and a lower second blade 4b. When the drive disk 51 rotates, it can synchronously drive the first transmission part 52 and the second transmission part 53. The first transmission part 52 is used to drive the upper first blade 3a and the lower first blade 4b. The blade 3b generates a synchronized opposing opening and closing action to control the air outlet of one air duct. The second transmission unit 53 is used to drive the upper second blade 4a and the lower second blade 4b respectively. The upper second blade 4a controls the air outlet of one air duct by rotating independently, and the lower second blade 4b controls the air outlet of one air duct by rotating independently. This realizes the control of four blades by one actuator 2, and thus controls the air outlet of three air ducts, realizing multiple air outlet modes. Compared with the design of using two motors, a set of motors and their control system is omitted, thereby saving space and the cost of motors and their control systems.

[0059] like Figure 3 As shown, in some embodiments, the protective shell 1 includes a shell near the first blade 3 and the second blade 4, and a cover detachably connected to the shell, wherein the drive disk 51 is rotatably connected to the shell, and the actuator 2 is fixedly connected to the cover.

[0060] Please continue reading. Figure 3The drive disk 51 includes a drive shaft 511 connected to the actuator 2, and a track groove X512, track groove Y513, and track groove Z514 that are disposed through the drive shaft 511. The track groove X512 is used to drive the first transmission part 52, and the track groove Y513 and track groove Z514 are used to drive the second transmission part 53.

[0061] In use, a drive shaft 511 is provided on a drive disk 51 and connected to the actuator 2 so that the actuator 2 drives the entire drive disk 51 to rotate through the drive shaft 511; a track groove X512, a track groove Y513, and a track groove Z514 are provided on a drive disk 51, and the track groove X512 drives the first transmission part 52, and the track groove Y513 and the track groove Z514 drive the second transmission part 53, thereby driving the first blade 3 and the second blade 4.

[0062] Please continue reading. Figure 4 The first transmission unit 52 includes a first gear 521 for driving the upper first blade 3a to open and close, and a second gear 522 that meshes with the first gear 521 and drives the lower first blade 3b to open and close. The first gear 521 includes a first drive rod 5211, which cooperates with the track groove X512 so that the track groove X512 drives the upper first blade 3a and the lower first blade 3b to open and close in opposite directions.

[0063] In use, the first drive rod 5211 cooperates with the track groove X512. When the drive disk 51 is driven to rotate by the actuator 2, the track groove X512 will drive the first drive rod 5211 to rotate, which in turn drives the first gear 521 to rotate. While rotating, the first gear 521 can drive the upper first blade 3a to rotate, and can also drive the second gear 522 to rotate synchronously in the opposite direction through meshing. The second gear 522 can drive the lower first blade 3b to rotate synchronously, thereby realizing the opposite opening and closing action of the upper first blade 3a and the lower first blade 3b controlled by the first transmission unit 52.

[0064] Please continue reading. Figure 5 The second transmission unit 53 includes an upper second transmission unit 53a and a lower second transmission unit 53b, which are slidably connected to the protective shell 1 in an upper and lower position. The second transmission unit 53 includes a second drive rod 531. The upper second transmission unit 53a cooperates with the track groove Y513 through the second drive rod 531, so that the track groove Y513 drives the upper second blade 4a to rotate. The lower second transmission unit 53b cooperates with the track groove Z514 through the second drive rod 531, so that the track groove Z514 drives the lower second transmission unit 53b.

[0065] In use, since the upper second blade 4a and the lower second blade 4b each need to control the airflow of one duct, the second transmission unit 53 includes an upper second transmission unit 53a and a lower second transmission unit 53b. The second drive rod 531 of the upper second transmission unit 53a cooperates with the track groove Y513, and the second drive rod 531 of the lower second transmission unit 53b cooperates with the track groove Z514. When the drive disk 51 is driven to rotate by the actuator 2, the track groove Y513 will drive the upper second transmission unit 53a to move through the second drive rod 531, and drive the upper second blade 4a to rotate. The track groove Z514 will drive the lower second transmission unit 53b to move through the second drive rod 531, and drive the lower second blade 4b to rotate. This achieves the goal of driving one drive disk 51 through one actuator 2, which can drive the upper first blade 3a and the lower first blade 3b to open and close in opposite directions, while also driving the upper second blade 4a and the lower second blade 4b to perform the required rotational actions, thereby reducing the space occupied and the overall cost.

[0066] Please refer to further information. Figure 4 The first blade 3 includes a first driving block 31 disposed at one end and a plurality of fan-shaped protrusions 32 disposed around the outer wall of the first driving block 31; the first gear 521 includes a through hole 5212 and a first fan-shaped groove 5213 disposed around the outer wall of the first through hole 5212; the second gear 522 includes a through hole 5221 and a second fan-shaped groove 5222 disposed around the outer wall of the second through hole 5221; the first driving block 31 of the upper first blade 3a cooperates with the first through hole 5212, and the fan-shaped protrusion 32 cooperates with the first fan-shaped groove 5213; the first driving block 31 of the lower first blade 3b cooperates with the second through hole 5221, and the fan-shaped protrusion 32 cooperates with the second fan-shaped groove 5222; the protective shell 1 includes an arc groove 11, the first driving rod 5211 passes through the arc groove 11 and cooperates with the track groove X512 under the constraint of the arc groove 11.

[0067] In use, the first drive block 31 of the upper first blade 3a is installed in the first through hole 5212. At the same time, multiple fan-shaped protrusions 32 are engaged in multiple first fan-shaped grooves 5213. This design ensures a stable connection between the upper first blade 3a and the first gear 521, and also facilitates the first gear 521 to stably drive the upper first blade 3a to rotate synchronously. The first drive block 31 of the lower first blade 3b is installed in the second through hole 5221. At the same time, multiple fan-shaped protrusions 32 are engaged in multiple second fan-shaped grooves 5222. This design ensures a stable connection between the lower first blade 3b and the second gear 522, and also facilitates the second gear 522 to stably drive the lower first blade 3b to rotate synchronously. In addition, the arc groove 11 on the protective shell 1 has a limiting function. When the track groove X512 drives the first drive rod 5211, the first drive rod 5211 slides in the arc groove 11, making the movement of the first drive rod 5211 more stable and the movement control of the upper first blade 3a and the lower first blade 3b more precise.

[0068] Please refer to further information. Figure 5 ,in,

[0069] The second transmission part 53 includes two slide grooves 532 disposed on both sides along the width direction, and a drive groove 533 disposed through the thickness direction;

[0071] The second drive rod 531 of the upper second transmission part 53a passes through the straight groove 12 and is driven to move up and down by the track groove Y513 under the constraint of the straight groove 12; the second drive rod 531 of the lower second transmission part 53b passes through the straight groove 12 and is driven to move up and down by the track groove Z514 under the constraint of the straight groove 12.

[0072] The second blade 4 includes a drive arm 41 disposed at one end. One end of the drive arm 41 is provided with a drive guide post 411. The drive guide post 411 is inserted into the drive groove 533 so that the second transmission part 53 drives the second blade 4 to rotate when it moves up and down.

[0073] In use, the two slide grooves 532 respectively cooperate with the two slide rails 13 on the protective shell 1. When the drive disk 51 rotates, the track grooves Y513 and Z514 respectively drive the upper second transmission part 53a and the lower second transmission part 53b to move up and down along the two slide rails 13. The second blade 4 includes a drive swing arm 41, one end of which is provided with a drive guide post 411. The drive guide post 411 is inserted into the drive groove 533, thereby converting the up and down movement of the upper second transmission part 53a and the lower second transmission part 53b into the rotational movement of the upper second blade 4a and the lower second blade 4b respectively. In addition, the protective shell 1 includes a straight groove 12, which has a limiting effect on the second drive rod 531. When the upper second transmission part 53a and the lower second transmission part 53b move up and down along the two slide rails 13, the second drive rod 531 can cooperate with it, making the up and down movement more stable and the movement control of the upper second blade 4a and the lower second blade 4b more precise.

[0086] When the drive disc 51 continues to rotate through angle A6, the first drive lever 5211 is at the fully open point Xg, one of the second drive levers 531 is at the closed point Yg, and the other second drive lever 531 is at the closed point Zg; at this time, the first air duct 61 and the third air duct 63 are closed, and the second air duct 62 blows out strong wind.

[0087] Please continue reading. Figure 7 , where A1=A2=A3=A4=A5>A6.

[0088] In some embodiments, A1 = A2 = A3 = A4 = A5 = 30°, A6 = 19.2°.

[0089] It is worth mentioning that, as shown in 8-20, there is an installation space between the first air duct 61 and the third air duct 63, and the outlet of the second air duct 62 is located in the installation space. Therefore, in some embodiments, a diversion air duct 7 can be set in the installation space to guide the air outlet of the second air duct 62, which cooperates with the first blade 3 to enable the second air duct 62 to have the wind direction, wind speed and wind type required by the user.

[0090] Specifically, the air duct 7 includes an outer shell 71, a guide cavity 72 disposed within the outer shell 71, and a soft air plate 73 disposed at the outlet of the guide cavity 72. The cross-sectional shape of the guide cavity 72 in the first direction is trapezoidal, and the area of ​​the guide cavity 72 gradually increases in the second direction, so that the air gradually disperses from the middle to both sides as it moves from the inlet to the outlet of the guide cavity 72. When the air does not pass through the air duct 7, it disperses to both sides along the two sides of the trapezoid. As the area of ​​the guide cavity 72 gradually increases in the second direction, the dispersion effect is further improved, thereby reducing the impact of pressure drop and ensuring the temperature environment inside the vehicle under constant power, thus meeting the user's needs. Furthermore, the soft air plate 73 can make the air duct 7 blow out a windless breeze, thereby meeting the user's needs for the type of airflow.

[0091] Furthermore, the air guide cavity 72 includes a central flow channel 721 and multiple side flow channels 722 symmetrically arranged on both sides of the central flow channel 721; the central axis of the side flow channel 722 and the central axis of the central flow channel 721 form an angle, and the angle increases with the increase of the distance between the side flow channel 722 and the central flow channel 721.

[0092] Furthermore, the soft air plate 73 includes a first soft air plate body 731 and a second soft air plate body 732 formed by bending; the first soft air plate body 731 and the second soft air plate body 732 are set at an obtuse angle; the first soft air plate body 731 and the second soft air plate body 732 are provided with a plurality of through holes 733, the through holes 733 are distributed from the air outlet of the middle flow channel 721 to the air outlets of the side flow channels 722 on both sides, and the size of the through holes 733 decreases as the distance from the air outlet of the middle flow channel 721 increases.

[0093] In use, by bending the soft wind plate 73 into a first soft wind plate body 731 and a second soft wind plate body 732 with obtuse angles, the wind, upon reaching the soft wind plate 73, disperses in different directions after passing through the first soft wind plate body 731 and the second soft wind plate body 732, further improving the dispersion effect and reducing the impact of pressure drop. The first soft wind plate body 731 and the second soft wind plate body 732 are provided with multiple through holes 733, which makes the wind softer when it blows out through the through holes 733, reducing the discomfort caused by the wind blowing directly on the human body. In addition, in this embodiment, the size of the through holes 733 decreases as the distance from the air outlet of the middle flow channel 721 increases, which is beneficial for matching the side flow channel 722 with a gradually increasing angle.

The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
