DETAILED DESCRIPTION

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] See also Figure 1-15 As shown: A natural wind outlet, comprising: The air outlet housing 1 is provided with an air duct 1.1 and a first air outlet channel 1.11 and a second air outlet channel 1.12 communicating with the air duct; The second air outlet channel 1.12 is spaced apart from the first air outlet channel 1.11 in the vertical direction. The first air outlet channel 1.11 outputs a first airflow, and the second air outlet channel 1.12 outputs a second airflow intersecting with the first airflow; A plurality of second blades 3 are arranged in the second air outlet channel 1.12. The plurality of second blades 3 swing back and forth to output a second airflow that swings left and right. Along the left and right directions of the outlet area of ​​the first airflow, the second airflow circulation changes and intersects with the first airflow, the air volume in the intersecting area increases and is greater than the air volume in the non-intersecting area, and then the airflow is output with the air volume ratio of natural wind.

[0033] The device has a natural wind outlet mode. In the natural wind outlet mode: the first air outlet channel 1.11 outputs a relatively stable (no left and right swing) first airflow, and the outlet area of ​​the first airflow is relatively fixed; At this time, a plurality of second blades 3 swing back and forth to output a second airflow that swings back and forth. In the movement trajectory of the second airflow, there is an intersection area and a non-intersection area between the air outlet area of ​​the first airflow, wherein the air volume in the intersection area is increased by the second airflow and is greater than the air volume in the non-intersection area, and the intersection area changes repeatedly with the left and right swing of the second airflow, so that when using it, the user can experience the wind feeling of natural wind that is locally strong and locally weak (that is, the airflow has local strong and weak changes), so that the airflow output from the air outlet is similar to the air volume ratio of natural wind; Compared with the direct blowing air outlet mode, the wind feeling is better, which improves the user comfort. In addition, the device also has the characteristics of simple structure and stable and reliable operation.

[0034] See also Figure 5 As shown, a plurality of first blades 2 are arranged in the left-right direction in the first air outlet channel 1.11. The plurality of first blades 2 can swing left-right and can swing to a position inclined to the left and right sides, so that the first air outlet channel 1.11 outputs a first airflow that diffuses to the left and right sides.

[0035] After the above improvements, several first blades 2 can be swung to a position inclined to the left and right sides, so that the first air outlet channel 1.11 outputs the first airflow that diffuses to the left and right sides. At this time, the first airflow that diffuses can expand the air outlet area. When the second airflow swings left and right, the intersection area with the first airflow increases, thereby increasing the air outlet range of the natural wind.

[0036] See also Figure 3 As shown, the plurality of second blades 3 and the plurality of first blades 2 are independently arranged up and down correspondingly, and the plurality of first blades 2 and the plurality of second blades 3 can swing left and right together to make the first air outlet channel 1.11 and the second air outlet channel 1.12 output airflow in the same direction.

[0037] The device also has a parallel (straight blowing) air outlet mode. In the parallel air outlet mode, a plurality of first blades 2 swing left and right to adjust the left and right air outlet angles of the first airflow, and a plurality of second blades 3 swing left and right to adjust the left and right air outlet angles of the second airflow. The left and right swinging angles of the first blades 2 and the second blades 3 are consistent, so that the left and right air outlet angles of the first airflow are consistent with the left and right air outlet angles of the second airflow, and the two airflows converge to output airflows in the same direction.

[0038] The first blade 2 and the second blade 3 are independently arranged relative to each other up and down. When the left and right swing angles of the first blade 2 and the second blade 3 are consistent, the guiding angles of the airflow are the same. When the two airflows meet, the airflows meet in an orderly and stable manner, thereby making the output airflow feel better.

[0039] See also Figure 2 , Figure 4 , Figure 5 ,as well as Figure 8 As shown, a bracket 4 is provided on the air outlet housing 1 between the first air outlet channel 1.11 and the second air outlet channel 1.12, and a first sliding block 5 which can move forward and backward is provided below the bracket 4; The first slider 5 is provided with a first transmission slot structure extending forward and backward, and the first transmission slot structure is transmission-connected with a plurality of first blades, and the first transmission slot structure includes, from front to back, a first left-right swing track section 5.1, a diffuser outlet angle adjustment track section 5.2, and a first angle locking track section 5.3 which are sequentially connected; The first slider 5 moves forward and backward, and drives the first blades to have parallel left-right swinging motion trajectories, independent left-right swinging motion trajectories, and left-right swinging stop positions in sequence through the first transmission slot structure. The first blade 2 includes a first blade a2.1, a first blade b2.2, a first blade c2.3, a first blade d2.4, a first blade e2.5, a first blade f2.6, and a first blade g2.7 which are arranged transversely in the first air outlet channel 1.11, wherein the first blade f2.6 and the first blade g2.7 are linked to each other via a connecting rod; The first transmission groove structure includes a first track groove 11, a second track groove 12, a third track groove 13, a fourth track groove 14, a fifth track groove 15, and a sixth track groove 16 which are arranged transversely on the first slider 5; Among them, the first track groove 11 is combined with the transmission pin of the first blade a2.1, the second track groove 12 is combined with the transmission pin of the first blade b2.2, the third track groove 13 is combined with the transmission pin of the first blade c2.3, the fourth track groove 14 is combined with the transmission pin of the first blade d2.4, the fifth track groove 15 is combined with the transmission pin of the first blade e2.5, and the sixth track groove 16 is combined with the transmission pin of the first blade f2.6; When the transmission pin of each first blade is at the head end of the first left-right swing track section 5.1 of the combined track groove, each first blade is at a position where it swings to the left to the limit. When the first slider 5 moves backward, the first left-right swinging track section 5.1 drives each first blade to gradually swing rightward. When entering the rear end of the first left-right swinging track section 5.1, each first blade is at a position where it swings rightward to the limit. If the first air outlet channel 1.11 is required to output the first airflow diffused to the left and right sides: each first blade is required to swing to the left and right sides, and the first blade a2.1 is in a position where it swings to the right to the limit at this time. The first blade a2.1 does not need to swing to the left much. Therefore, the diffuse air outlet angle adjustment trajectory segment 5.2 of the first trajectory groove 11 can be set shorter and with a smaller inclination angle. The rear end of the first left and right swinging trajectory segment 5.1 of the first trajectory groove 11 is directly connected to the first angle locking trajectory segment 5.3, and the transmission pins of the remaining first blades enter the diffuse air outlet angle adjustment trajectory segment 5.2 and gradually rotate to the left until the first blade d2.4 is vertical, and the multiple first blades on the left side of the first blade d2.4 are in a position tilted to the left, and the multiple first blades on the right side of the first blade d2.4 are in a position tilted to the right. At this time, the first air outlet channel 1.11 outputs the first airflow diffused to the left and right sides.

[0040] See also Figure 4 , Figure 5 , Figure 6 , Fig. 9 , Fig.10 As shown, a second slider 6 that can move forward and backward is arranged above the bracket 4, and the second slider 6 is provided with a seventh track groove 6.1 extending forward and backward, and the seventh track groove 6.1 includes a second left-right swing track segment a6.11, a second angle locking track segment 6.12, and a second left-right swing track segment b6.13 that are connected in sequence from front to back; The second slider 6 moves forward and backward, and drives the plurality of second blades 3 to have a motion trajectory of parallel left-right swinging, a position where the left-right swinging stops, and a motion trajectory of parallel left-right swinging in sequence through the seventh track groove 6.1.

[0041] A plurality of second blades 3 are linked to each other through a linkage rod, that is, they swing left and right in parallel; The transmission pin of one of the second blades 3 is engaged with the seventh transmission groove 6.1. When the transmission pin of the second blade 3 reaches the beginning of the second left-right swing track section a6.11 of the seventh track groove 6.1, at this time, each second blade 3 is in a position where it swings to the left to the limit, When the second slider 6 moves backward, the second left-right swinging track section a6.11 drives each second blade 3 to gradually swing to the right. When entering the rear end of the second left-right swinging track section a6.11, each second blade 3 is at a position where it swings to the right to the limit. When the second slider 6 continues to move backward, the transmission pin of the second blade 3 enters the second angle locking track section 6.12, and the second angle locking track section 6.12 cannot drive each second blade 3 to swing left and right; When the second sliding block 6 continues to move backward, the transmission pin of the second blade 3 enters the second left-right swinging track section b6.13, and the second left-right swinging track section b6.13 drives the second blade 3 to gradually swing to the left; When the second slider 6 moves back and forth, the transmission pin of the second blade 3 moves back and forth in the second left and right swinging trajectory section b6.13, driving the second blade 3 to swing back and forth in a circular manner, so that the second air outlet channel 1.12 outputs a second airflow that swings left and right. At this time, combined with the first airflow that diffuses to the left and right sides, an airflow similar to natural wind can be formed.

[0042] See also Figure 4 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 ,as well as Fig.11 As shown, the bracket 4 is also provided with a rocker arm 7, and the rocker arm 7 is provided with a transmission rod 7.1, one end of the transmission rod 7.1 is connected to the first slider 5, and the other end is connected to the second slider 6, and the rocker arm 7 is provided with a gear ring 7.2. The bracket 4 is also provided with a first actuator 8, and the output end of the first actuator 8 is provided with a gear 8.1, and the driving gear 8.1 is meshed with the ring gear 7.2; The first actuator 8 drives the gear 8.1 to rotate, and the gear 8.1 rotates through the gear ring 7.2 to drive the rocker arm 7 to rotate, and the rocker arm 7 rotates through the transmission rod 7.1 to drive the first slider 5 and the second slider 6 to move forward or backward synchronously; Among them, the first left and right swinging trajectory segment 5.1 matches the second left and right swinging trajectory segment a6.11 in stroke, the diffuse air outlet angle adjustment trajectory segment 5.2 matches the second angle locking trajectory segment 6.12 in stroke, and the first angle locking trajectory segment 5.3 matches the second left and right swinging trajectory segment b6.13 in stroke.

[0043] The rear end of the rocker arm 7 is rotatably connected to the bracket 4 and can rotate forward and backward. The ring gear 7.2 is arranged at the rear end of the rocker arm 7 and meshes with the gear 8.1 at the output end of the first actuator 8; The rocker arm 7 is provided with a slot which passes through from top to bottom, and a transmission rod 7.1 is vertically passed through the slot. The lower end of the transmission rod 7.1 is hinged to the first slider 5, and the upper end is hinged to the second slider 6. The rocker arm 7 is driven to rotate by the first actuator 8, and the rocker arm 7 causes the first slider 5 and the second slider 6 to move forward or backward synchronously through the transmission rod 7.1.

[0044] When the transmission pin of each first blade is in the first left-right swinging trajectory section 5.1, the transmission pin of the second blade 3 is in the second left-right swinging trajectory section, the left-right swinging angles of the first blade and the second blade 3 are the same, so that the left-right outlet angles of the first airflow and the second airflow are the same, realizing a direct blowing air outlet mode.

[0045] When each first blade enters the first angle locking section, each first blade has been adjusted from the diffuser outlet angle adjustment track section 5.2 to the diffuser outlet position state, and the transmission pin of the second blade 3 is in the second left-right swing track section. At this time, the first actuator 8 drives the rocker arm 7 to reciprocate within a certain angle range, and the transmission pins of each first blade are kept in the first angle locking track section 5.3, and the transmission pins of the second blade 3 are in the second left and right swinging track section. When the first slider 5 moves forward and backward, the first blades do not swing left and right. When the second slider 6 moves forward and backward, the second blades 3 can be driven to swing left and right, thereby realizing a natural wind outlet mode.

[0046] See also Figure 4 , Figure 6 , Figure 8 , Fig. 9 , Fig.10 ,as well as Fig.11 As shown, first slide grooves 4.1 are respectively arranged on both sides of the first slider 5 below the bracket 4, and the first slide groove 4.1 includes a first horizontal section 4.11, a first inclined section a4.12 arranged at the front end of the first horizontal section 4.11, and a first inclined section b4.13 arranged at the rear end of the first horizontal section 4.11. After the first inclined section a4.12 and the first inclined section b4.13 are connected to the first horizontal section 4.11, they are respectively extended in an inclined direction upward; The first slider 5 includes a slider a5.4 and a slider aa5.5, wherein the slider aa5.5 is hinged at the rear end of the slider a5.4, and the left and right ends of the slider a5.4 and the slider aa5.5 are respectively provided with pins extending into the first slide groove 4.1; A second slide groove 4.2 is respectively arranged on the left and right sides of the bracket 4 corresponding to the second slide block 6. The second slide groove 4.2 includes a second horizontal section, a second inclined section a4.22 arranged at the front end of the second horizontal section, and a second inclined section b4.23 arranged at the rear end of the second horizontal section. After the second inclined section a4.22 and the second inclined section b4.23 are connected to the second horizontal section, they are respectively arranged to extend downward in an inclined manner. The second slider 6 comprises a slider b6.4 and a slider bb6.5, wherein the slider bb6.5 is hinged at the rear end of the slider b6.4, and the left and right ends of the slider b6.4 and the slider bb6.5 are respectively provided with pins extending into the first slide groove 4.1.

[0047] After the above improvement, when the first slider 5 slides in the first slide groove 4.1, when the slider a5.4 enters the first inclined section a4.12, the slider aa5.5 is in the first horizontal section 4.11, and the inclined structure of the first inclined section a4.12 makes the slider a5.4 fold relative to the slider aa5.5. When the slider aa5.5 enters the first inclined section b4.13, the slider a5.4 is in the first horizontal section 4.11. The inclined structure of the first inclined section b4.13 allows the slider aa5.5 to be folded relative to the slider a5.4. When the second slider 6 slides in the second slide groove 4.2, when the slider b6.4 enters the second inclined section a4.22, the slider bb6.5 is in the second horizontal section. The inclined structure of the second inclined section a4.22 causes the slider b6.4 to fold relative to the slider bb6.5. When the slider bb6.5 enters the second inclined section b4.23, the slider b6.4 is in the second horizontal section, and the inclined structure of the second inclined section b4.23 causes the slider bb6.5 to fold relative to the slider b6.4; After the above improvements, the compactness of the structure is further improved and the space occupied is reduced.

[0048] See also Figure 1 , Figure 2 , Fig.12 , Fig.13 , Fig.14 ,as well as Fig.15 As shown, the air duct 1.1 is also provided with an air volume blade 9, which is arranged between the entrance of the first air outlet channel 1.11 and the entrance of the second air outlet channel 1.12. The air volume blade 9 rotates up and down to adjust the entrance opening of the first air outlet channel 1.11 or the entrance opening of the second air outlet channel 1.12.

[0049] The direction of the first airflow outputted from the first air outlet channel 1.11 can be configured as an upward direction, and the direction of the second airflow outputted from the second air outlet channel 1.12 can be configured as a downward direction. The air volume blade 9 may be a fan-shaped cylindrical structure, with the side with a larger area being arranged close to the entrance of the air outlet channel. The rotating shaft 9.1 of the air volume blade 9 extends to the outside of the air outlet housing 1 and is transmission-connected to the output end of the second actuator 17 on the outside of the air outlet housing 1. When the second actuator 17 drives the rotating shaft 9.1 to rotate to drive the air volume blade 9 to rotate up and down, the inlet opening of the first air outlet channel 1.11 or the inlet opening of the second air outlet channel 1.12 can be adjusted to control the incoming air volume (the opening increases, the air flow increases, and the opening decreases, the air flow decreases). If the opening of one of the inlets is smaller than the opening of the other inlet, at this time, after the first airflow and the second airflow meet, they tend to be output in the direction of the airflow output of the air outlet channel with a larger opening.

[0050] After the above improvements, the angle of the output airflow can also be adjusted in the up and down directions, further increasing the functionality of the device and improving the user experience.

One gear 10.1 is provided with a coaxial transmission member 10.11, and the transmission member 10.11 is provided with a cam groove 10.111. The shaft 9.1 is extended with an extension portion 9.11, and the extension portion 9.11 is provided with a protrusion 9.111. When the shaft 9.1 rotates to a certain angle, the protrusion 9.111 can enter the cam groove to form a transmission connection. At this time, the continued rotation of the shaft 9.1 can rotate the gear 101 through the transmission connection between the protrusion 9.111 and the cam groove 10.111, so that the damper 10 has a position of closing the air duct 1.1. When the rotating shaft 9.1 rotates to move the projection 9.111 out of the cam groove 10.111, the gear 10.1 can be rotated in the reverse direction, so that the damper 10 has a position to open the air duct 1.1.

After the protrusion 9.111 enters the cam groove 10.111, the guide surface 9.2 and the guide groove 10.112 are disengaged. After the protrusion 9.111 moves out of the cam groove 10.111, the guide surface 9.2 is re-fitted with the guide groove 10.112, and the rotation of the shaft 9.1 can drive the air volume blade 9 to rotate up and down to adjust the inlet opening of the first air outlet channel 1.11 or the inlet opening of the second air outlet channel 1.12; This device also has the advantages of: 1. Compared with other air outlet devices on the market, this device has multiple functions (with parallel air outlet mode and natural wind outlet mode), better integration, better user experience, and occupies relatively less space, making it suitable for installation in cramped cars.

[0055] 2. The area between the first air outlet channel 1.11 and the second air outlet channel 1.12 of the air outlet housing 1 is recessed backward to form an assembly space 1.2. The bracket 4 and the drive mechanism installed therein are both arranged in the assembly space 1.2, which is conducive to reducing space occupancy and making the device more compact, suitable for assembly in a car with limited space.

[0056] 3. The structural design of the driving mechanism ensures that the trajectory of the first slider 5 and the second slider 6 during movement has no empty travel and no risk of jamming between the blades; 4. If the space in one direction is reduced or the two channels are not parallel, a reduced version of this mechanism plus an auxiliary rack + connecting rod will be used to achieve the functions of the above-mentioned parallel air outlet mode and the natural wind outlet mode.
